Embryonic Stem Cells No Longer Needed?

first_imgTwo announcements this week may make harvesting embryonic stem cells obsolete.  First, it’s not necessary to kill an embryo to get a stem cell, reported Associated Press (see Fox News) and Live Science.  While this does not solve all the ethical problems, a White House spokeswoman called it “encouraging to see scientists at least making serious efforts to move away from research that involves the destruction of embryos.”  Robert P. George later claimed in National Review that the hype was a lie.  The technique did involve the destruction of embryos.  He argued, though, that the push for alternative techniques shows that the researchers recognize the need to find ways to address the ethical issues surrounding stem cell technology; this, he said, is a “welcome development.”    Second, and more significant, Japanese scientists found that adult stem cells can be made pluripotent, like embryonic stem cells, by the addition of a few factors.  A press release on EurekAlert expresses the benefit of this procedure:“Human embryonic stem cells might be used to treat a host of diseases, such as Parkinson’s disease, spinal cord injury, and diabetes,” said Shinya Yamanaka of Kyoto University in Japan.  “However, there are ethical difficulties regarding the use of human embryos, as well as the problem of tissue rejection following transplantation into patients.”    Those problems could be circumvented if pluripotent cells could be obtained directly from the patients’ own cells.Obviously these announcements are too early to know the impact.  “While the findings could have wide applications, stem cell experts caution that the study of embryonic stem cells has much further to go,” the press release said.The first method still presents ethical problems.  The technique could cause unknown damage to the embryo, and the cell that is taken out, if it could still grow into a human being, does not circumvent the ethical issues.  In fact, pro-life groups are already speaking out against it according to the AP article.  The second technique looks much more promising and is the one to watch.  If adult stem cells can have all the advantages of ES cells, including the holy grail of pluripotency, it pulls out the rug from under all arguments for needing to destroy embryos to get at their pluripotent stem cells.  If scientists continue to push for ES cells then, their true motives will be unmasked.    An important lesson from these two stories is that pressure from ethicists and concerned citizens is essential for reining in the otherwise out-of-control ambitions of scientists about ES cells.  Science is not ethically neutral.  It cannot operate outside of a social context.  The citizens who fund research and expect to reap the benefits need to monitor the direction science is going and voice their concerns when researchers look like they are about to cross the line.  For instance, read this EurekAlert press release, “Brave new world in life sciences,” about threats to public health and safety from new kinds of research.(Visited 12 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

How Well Do We Know What Stuff Is Made Of?

first_imgWhen we think of the “hard sciences,” physics usually tops the list.  A closer look at what physicists think the universe is made of, though, hardly makes the science look hard.  Look at this headline on PhysOrg, for instance: “Study finds there may be multiple ‘God particles’”.  The title refers, of course, to the famed Higgs Boson, not to some supernatural entity.  The Large Hadron Collider was hoping to find evidence of this particle that Nobel laureate Leon Lederman called the “God particle” because, he said, its discovery could help unify our understanding of the universe and “know the mind of God.”  But now, according to Fermilab scientists, there might be five versions of the Higgs boson (which hasn’t been discovered yet).    Frank Close wrote a book review in Nature this week on this subject.1  The book is Massive: The Hunt for the God Particle by Ian Sample.  He points out that particle physicists hate the label “god particle” that the media continue to give it, and notes that “many argue that it should not be called the Higgs boson because the concept has a longer history.”  It turns out there is as much sociology, theory and nomenclature at work as physics in the conception of what lies at the foundations of matter.  A sample:Whereas the W and Z bosons that carry the weak force make use of this mechanism, the photon that carries the electromagnetic force does not; it remains massless.  Why this happens remains unanswered….    Behind all this theory lies the work of another British physicist, Jeffrey Goldstone.  In his investigation of spontaneous symmetry breaking in 1961, Goldstone identified two bosons that played a part: one was massive, the other massless.  Both differed from the photon or W boson in that they lacked the intrinsic quantum property of spin.  Empirical evidence indicated that the massless Goldstone boson does not exist, flagging up a theoretical quandary that received much attention at the time from those who hoped to use the theory as a basis for uniting the weak and electromagnetic interactions.  The mechanism discovered by the three groups of physicists in 1964 explained how Goldstone’s massless boson could disappear, in the process giving a mass to the W boson that transmits the weak force.  It thus solved two problems for the price of one, and paved the way for the modern theory of the ‘electroweak’ force.    Sample recognizes this work but overlooks its massive counterpart, which is where the excitement lies today.  The irony is that it also went largely ignored in 1964.  Brout and Englert made no mention of it in their paper, although they were aware of its manifestation in condensed-matter physics.  Guralnik, Hagen and Kibble suppressed it in their analysis, which was simplified to focus on the removal of its massless companion.  Higgs alone pursued it.  What is being called Higgs’s boson is, in effect, Goldstone’s massive boson.  Although at least six physicists can lay claim to this particular mechanism for generating mass, only Higgs realized the importance of the massive boson in testing the theory.An understanding of the terms is not as important as a perception that various competing teams appeared to be playing with shadows in the dark, and making up concepts as they went along.  Can a particle really be a carrier of a force?  Can mechanisms generate mass just because a theory needs it?  Where is the mass coming from?  As useful as the terms and nomenclature become to theory, does nature owe any obligation to conform to human conceptions?  Did nature suddenly change properties this year when one Higgs boson became five?    The intuitive answer to such questions is that of course nature didn’t change: we did.  Our scientific understanding of nature changed.  But then can we assume it is improving?  Is it evolving?  Is our understanding continuously changing, and if so, is there any point at which we can say we understand something with a sufficient degree of certainty?  At what point do we jettison things textbooks have been teaching for decades?  Can we assume we have the story right now?  What unforeseen discoveries in the next few years will have us regretting that what we are learning in 2010 is all wrong?    These are serious questions, underscored by another example in New Scientist this week, “Anti-neutrino’s odd behaviour points to new physics,” as if all we need right now is a new physics (the hard science).  Reporter Anil Ananthaswamy wrote, “The astounding ability of these subatomic particles to morph from one type to another may have created another crack in our understanding of nature.”  This crack, he said, “cannot be explained by standard model physics.”  Granted, neutrino physics experiments are difficult, but a Fermilab test of theory produced unexpected results.  Jenny Thomas of University College London put a happy face on it: “If the effect is real, then there is some physics that is not expected.  Then there is something new that we don’t understand, and that’s fantastic.”1.  Frank Close, “How the boson got Higgs’s name,” Nature 465, pp. 873�874, 17 June 2010, doi:10.1038/465873a.Rejoicing in one’s ignorance may be an exuberant form of humility, but it is not the kind of progress one expects from multi-million-dollar investments in science.  Remember this next time you watch some TV program boasting about how scientists are on the verge of coming up with a “theory of everything.”  For an excellent background on the Standard Model and what it does and does not explain, read David Berlinski’s penetrating essay, “The State of the Matter” (The Deniable Darwin and Other Essays, Discovery Institute, 2009.)  Also recommended are the lectures on scientific reduction (23-24) in Jeffrey Kasser’s Teaching Company series on Philosophy of Science, which ask what value is being added to explanation when things get reduced to fundamental physics.  In another Teaching Company series, Steven L. Goldman (Lehigh U) in Science in the 20th Century –: A Social-Intellectual Survey provides a colorful look at the personalities and milestones involved in quantum mechanics, quantum electrodynamics and quantum chromodynamics and how our views of “reality” changed dramatically over the last 100 years.  In another Teaching Company series, Science Wars, he asked what we mean by ‘reality,” whether science can approach it, and what confidence we can have that our concepts of reality will remain intact a century from now given that they have changed drastically and repeatedly over the past few centuries.    The reader should note that whether theories work is a separate question from whether they are true.  The Egyptians built the pyramids with remarkable precision while believing astrology.  We build cell phones and use GPS and lasers and a host of wondrous devices using quantum theory without a clue why nature behaves in the bizarre ways described by quantum mechanics.  How can something be a wave and a particle?  How can a photon pass through two slits at once?  How can two particles seem to interact instantaneously at a distance?  How can an observer play a role in the outcome of a quantum event?  We have no idea.  One mark of a good scientist is humility.(Visited 12 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Help for an Ailing Water Heater

first_imgPat Beurskens has been happy with his heat-pump water heater, but he fears the time is coming when it won’t be able to keep up with demand. He foresees the day when his young daughter will be using more hot water, and Beurskens is finishing out the basement of his Seattle home to be used as a rental. That, too, will increase hot water use. Against this backdrop, Beurskens’s GE Geospring, a model that has been discontinued, is showing signs of fatigue. “Lately,” he writes in a post at the Q&A forum, “the water heater has been maxing out after two showers. I’ll be retrofitting a 1.5 [gallon per minute] adapter, which will help, but I’m still nervous about having a tenant and running out of hot water.”RELATED ARTICLESBradford White Buys GeoSpring Rights and EquipmentDrainwater Heat Recovery Can Lower Your HERS ScoreAll About Water HeatersGet Ready for Heat-Pump Water HeatersDrainwater Heat Recovery Comes of Age In order to squeeze more capacity out of his system, Beurskens is considering a solar water heater and an electric tankless water heater. He’d prefer using the heat-pump water heater most of the time because of its high efficiency. He doesn’t want to replace it with a larger model because of the expense and because he’s not eligible for another rebate. He asks, “My main question is: Would it work to put the tankless electric heater in a series in front of the heat pump tank so that the tankless kicks on only when the tank starts dropping in temp?” That’s the question for this Q&A Spotlight. Avoid electric tankless heaters The best option would be to avoid an electric tankless water heater altogether, argues Dana Dorsett. “An electric tankless isn’t as sensitive to incoming water temps as fossil burners,” he writes, “but they are really abusive to the grid infrastructure, and one of the least green options there is.” Dorsett explains it this way: Assuming the incoming water is 52°F,  filling a tub with 110°F water at a a rate of 4 gallons per minute, would take 28,000 watts of electricity — a ginormous load, six times that of a standard electric water heater. That’s enough power, he adds, “to make the wires jump and the transformer serving your house heat up.” Even though the load is intermittent, and overall doesn’t add up to a lot of energy use, the grid infrastructure capable of delivering that amount of power has to be built and maintained. So, for those few minutes a week that the water heater might actually be needed, the fixed portion of everyone’s power bill goes up. Walter Ahlgrim adds that adding an electric tankless water heater as a retrofit in an existing house is “almost never a viable option.” The reason is that any unit that’s large enough to serve the whole house will draw more electricity than the existing panel can provide. “When you add the tankless water heater to the new electrical panel, with new meter base and heaver wires all the way to the pole, the number is more than most people will go for,” he says. Norman Bunn writes that he once had a tankless electric that required an additional 120 amps to operate. “Going this route may require you to not just upgrade the panel but get a larger feed from the pole,” he says. “That can be pricey.” Try a second standard water heater instead A better plan would be to install a second standard (tank-style) electric water heater in series with the heat-pump model, Dorsett suggests. The system would be designed so that the output of the heat-pump unit would feed the cold water inlet of the standard tank. Although the system would still suffer the standby losses common to all tank-style heaters, the auxiliary heater won’t be using much electricity until both tanks are nearly depleted. Consider drain-water heat recovery An even more attractive option would be install a drainwater heat recovery system — the “tallest and fattest” that will fit in the available space. These passive heat exchangers take the place of a section of standard drain line on a shower. Hot water going down the drain heats up incoming cold water, saving energy in the drainwater that is normally wasted. A 4-inch-diameter by 48-inch-long heat exchanger can save more than 50% of the heat that’s exiting the drain, Dorsett says. If the drainwater is 105°F, the 52°F incoming water is instantly heated to between 75°F and 80°F, depending on how quickly the water is moving. “That has two effects,” Dorsett says. “Less hot water is needed to mix with ~78°F water to get 105°F at the shower head, so less hot water is being drawn, and the water entering the water heater only has to be raised 27 F° rather than 53 F° by the water heater, which means a slower depletion time and a shorter recovery time.” That has the effect of increasing the effective capacity of the heat-pump water heater from 50 gallons to somewhere between 65 gallons and 75 gallons when someone is showering. (It won’t help when someone is drawing a tub.) Keep the new system simple Beurskens has heard enough to drop plans for an electric tankless and opt instead for a second tank-style heater, possibly with a recirculation pump. You don’t need a pump, GBA editor Martin Holladay tells him. Just install the new water heater downstream from the existing heat-pump water heater (HPWH) and set the new water heater’s aquastat 10 F° lower than the aquastat on the main water heater. A recirculation system would only increase the standby loss for a very small improvement in capacity, Dorsett adds. “Insulate all of the hot water distribution plumbing with R-3 foamy pipe insulation, including the 10 feet of cold feed nearest the HPWH, and the nearest 10 feet of temperature and pressure overflow plumbing,” Dorsett says. What about a new mixing valve? Beurskens suggests one other option. “Speaking of simplicity, and assuming the new hot water needs can be limited with flow restriction,” he says, “what are your thoughts on a Tank Booster mixing valve? Basically turning up the thermostat on the HPWH to increase load capacity. This would negate the need for any new tank.” A mixing valve could be used for those times when extra hot water will be needed, Bunn replies, but it wouldn’t be a good idea when the heat-pump water heater was capable of meeting the demand because that would mean more power consumption. Thermostatic mixing or tempering valves between water heaters and sinks and tubs are required by code in most locations, Dorsett says, although some pre-plumbed units can reduce flow significantly. “Turning up the storage temperature to 150°F or higher, and then mixing it down to 115°F with a thermostatic mixing valve can provide greater apparent capacity,” he says. “The down side to that is that a substantially higher storage temperature increases standby losses (not by more than adding a second tank, though), and lowers the heat pump’s raw efficiency.” The bottom line, Dorsett says, is that turning up the thermostat on the existing HPWH and using a mixing valve will be cheaper in terms of total energy consumption than adding a second tank. That’s because standby losses will be lower, and because the HPWH is more efficient than a standard electric tank even when set a higher temperature. Our expert’s opinion Here’s what GBA Technical Director Peter Yost has to add: Pat Beurskens has clearly done a lot of work and research to get the best domestic hot water he can configure for his situation. Here are some additional thoughts, particularly an extended one on drain water heat recovery. When a heat-pump water heater is in the basement, particularly in low-load homes, keep an eye on the temperature and relative humidity in your basement during the winter. The HPWH is removing BTUs from your basement air to heat water. Beurskens has a clever setup for his recirculating pump such that he decides when it runs. He has has set it up to manage energy and water efficiency for his most problematic draw, the most-used bath sink that shares a line with the shower. I sometimes worry that we are repeating the low-flow toilet debacle with showerheads. That is, reducing flow without making sure that performance is maintained. EPA WaterSense has added performance tests to its shower head spec (see EPA WaterSense Specifications Appendix A and B). But I still hear from plenty of consumers who feel that WaterSense-approved showerheads are not delivering enough water. In my own home, I resorted to purchasing a series of low-flow showerheads until my teenage daughter finally signed off. Long, thick hair seems to be the issue. It baffles me that given the difference in temperature between the tank water temperature and the air surrounding any tank water heater (let’s assume a 120°F tank temperature and 65°F air temperature in the basement — meaning a delta-T of 55 F°), that we don’t better insulate these tanks. See this ACEEE report indicating that an external insulation blanket can save approximately 28%. More on drain water heat recovery Mechanical engineer Dan Cautley, my close friend and colleague at SeventhWave in Madison, Wisconsin, who was my mentor in my first year at the NAHB Research Center in 1993, has done at least two research projects over the years on drainwater heat recovery, and he gave me this extended perspective on the topic: “A vertical pipe drain water heat recovery unit is a remarkably simple way to capture waste heat, and the ‘effectiveness’ (effectiveness is the fraction of available energy that’s captured through a heat exchanger) can be surprisingly high (50% and higher). But this doesn’t mean it’s necessarily cost-effective. “Horizontal pipe (sloped to drain) drain water heat recovery units may work fine, but are outside my experience. “Overall system heat recovery effectiveness will always be lower than rated heat exchanger effectiveness, mostly due to heat loss from the drain upstream of the heat exchanger. In my detailed study of three units in commercial buildings, measured overall system heat recovery effectiveness was generally 5 to 10 percentage points lower than the nominal effectiveness rating of the heat exchanger. Effectiveness also depends on flow rate – an issue that is probably beyond the scope of a short blog. “Dynamics (thermal mass) play a role. In general, thermal mass will reduce performance — think of taking a shower using 12 gallons of water, where it takes 3 gallons of flow to heat up the drain line and heat exchanger before reaching steady-state performance. (I found that it took about 6 gallons of flow to reach steady state in one system, and that wasn’t an extreme case.) This effect generally works against you – you don’t get full heat recovery instantly when the shower starts, plus you leave warm water in the heat exchanger when the shower ends, which is likely to cool back to room temperature. (And any cold water flowing down the drain will take this heat with it.) Thus the best application of a drain water heat recovery unit is where there are long episodes of hot water usage with simultaneous drain flow – a bank of showers in a fitness center would be ideal, while a residential shower is less so. “But that’s not the whole story. Dynamics can work to help heat recovery where there are short flows of warm drain water and cold supply water offset in time. We found surprisingly good performance in a restaurant in which a dishwasher filled, ran, and then drained, with little simultaneous flow of supply water and drain water. The thermal mass of the heat exchanger absorbed enough heat when the dishwasher drained to significantly heat the supply water passing through it a few minutes later. The water use in each dishwasher cycle was low — a gallon or so — which was an important factor. “Based on a 36-home study I did at the NAHB Research Center in the 1990s, my estimate of typical overall water heating energy savings in a residence is around 20%, but this will of course vary greatly with the specifics. “All this said, a drain water heat recovery unit will certainly increase the effective capacity of any storage tank water heater, i.e. allow longer showers, for the reasons that Dorsett mentions. The Dorsett claim does seem somewhat optimistic in terms of the size of this effect. “The bottom line: I love this simple, elegant technology, but it’s going to be really attractive only in limited applications. Here is a link to my report from the three-site study of commercial applications that I did 5 years ago. Take a look at page 34 of the report (page 38 of the PDF) for a list of criteria for selecting good applications. It’s written for commercial use, but the principles apply to residential use.”last_img read more

How Liverpool Built A Potential Champion

Seasons with Klopp 2015-16 only includes games when Klopp was manager.Source: Opta Sports In the round of 16, Liverpool got to face Porto and avoid a match against Real Madrid or Juventus. This increased the Reds’ chance of winning the Champions League from about three percent to about five percent. For the quarterfinals, Liverpool got a tough matchup in Manchester City, but most of the other remaining teams were also extremely strong, so the draw caused only marginal movement in Liverpool’s chances of winning the Champions League. Then the semifinal draw brought the greatest bounty, as the Reds avoided Bayern Munich and Real Madrid to face Roma instead. This increased Liverpool’s chance of winning the league from about 20 percent6The exact number was not available, so I extrapolated from the last number available before that draw. to 29 percent.The table to the left shows the net total improvement, in percentage points, of the chance SPI gave each team of winning the Champions League before and after the draw for each round. Among the teams that reached the quarterfinals, none benefited more than Liverpool. (And this calculation doesn’t even include Liverpool’s luck in the group draw, when the Reds were given the weakest of the eight groups.)Liverpool can winAs the table of team luck shows, Real Madrid has reached the Champions League final by facing a true gantlet. They got Paris Saint-Germain in the round of 16, Juventus in the quarters and Bayern Munich in the semifinals. However, the draw is not the only method by which good fortune may affect the outcome. Real would not have made the finals if Bayern Munich had not been extremely profligate with its chances. Bayern scored only three goals, but based on the chances the team got, we would expect them to have gotten 6.9 goals.But the way Bayern got all those chances bodes well for Liverpool. They pressed high and created turnovers. If Liverpool can execute its pressing game as effectively as Bayern did, the Reds should also be able to make trouble for Real Madrid. In this game, Liverpool’s defensive flexibility probably will be less help — sitting back and allowing Cristiano Ronaldo time to find space in the penalty area does not seem like the best option. With heavy metal soccer, Klopp may finally win a Champions League and bring a trophy back to Liverpool.CORRECTION (May 24, 2018, 6:15 p.m.): A previous version of this article incorrectly described Real Madrid’s path to the Champions League finals this year.

Firmino and Mane both similarly showed their potential before their Liverpool signings: Firmino’s production for Hoffenheim in 2014-15 and Mane’s for Southampton in 2015-16 were among the best player seasons in the sample I examined, which included non-striker attacking players in the five biggest leagues over the previous three seasons.3Minimum 2,500 minutes played combined between the player’s domestic league and the Champions League and European League. Liverpool used data to identify players who weren’t just on a hot streak but who demonstrated repeatable skills, and those purchases have paid off in goals.Liverpool adjusted to improve its defenseJurgen Klopp has called his style of play “heavy metal” soccer. His teams focus on creating and exploiting transition opportunities, the moments when neither team has established possession or set its defensive structure. His teams press high up the pitch, closing down opponents even when they have the ball well into their defensive half. In Klopp’s first season with Liverpool in 2015-16, his team led the league with a roughly 52 percent success rate in breaking up new opposition possessions. This metric calculates how often and how successfully a team closes down its opposition early in the opponent’s possession, which reflects the degree to which they implement a pressing defensive style.4Pressing rate is calculated by identifying when a new possession begins, and then tracking if the team in possession either completes three consecutive successful passes or completes an attack (by taking a shot, playing a pass into the penalty area, or winning a corner). If the possession is stopped, whether by a turnover, a foul or the ball going out of play for a throw-in, that counts as a “press.” The next season, with a year of training under their belt, Klopp’s players stepped up their pressure, breaking up nearly 54 percent of opposition possessions early. Once again, this rate led the league. However, there were some drawbacks to this style: In both those first two seasons, Liverpool was relatively vulnerable to direct attacks. If the first line of press failed, the Reds often found themselves chasing back to stop a counterattack headed for their goal. This is measured by direct attacks into the final third of the pitch, which shows when an opposition team can break forward into dangerous areas.5Direct attacks are calculated as attacking moves in which at least 50 percent of the movement is directly toward the goal, meaning that if you draw a straight line from where the attack started to where it ended and then measure the total distance the ball covered over all the passes and runs in the move, the ratio between those two distances must be at least 0.5.This season, Klopp has drilled his team to drop the pressing intensity in matches where it’s not needed. While they still can press high, Liverpool can also sit back and absorb pressure, as they did to great effect in the Champions League quarterfinal against Manchester City. This improved tactical flexibility has yielded results — reducing opponents’ goals, chances and successful fast attacking moves by a significant margin. The Champions League final seems immune to upsets. Real Madrid won three of the last five finals, with Bayern Munich and Barcelona taking the other two. And now Madrid is one win away from its fourth title in six years and third in a row. But this list of winners should not obscure that smaller clubs have come close. Atletico Madrid has taken Real Madrid to extra time twice in the last five finals, and Borussia Dortmund lost a nail-biter of a final 2-1 to Bayern. This year, it is Liverpool that has a real shot at upending a traditional power structure in the Champions League. And according to FiveThirtyEight’s Soccer Power Index, a Liverpool victory would not even be that much of an upset: SPI gives the team a 47 percent chance of lifting the trophy on Saturday.How did Liverpool become a true Champions League contender? To a certain degree, this is unsurprising. For starters, Liverpool is no upstart, at least historically. The club has five European Cups and its revenues are among the highest in European soccer.1Ninth highest last season, according to Deloitte. But the Reds have played in the Champions League only four times in the last decade, and this season is the first time they have even reached the knockout stages since 2009. It took an extensive and highly successful rebuilding effort to get Liverpool to the cusp of a European trophy. The three key components of this effort were smart analytics, innovative tactics and the usual helping of good luck.Liverpool struck gold in the transfer marketThe engine of this Liverpool team is its front line. Manager Jurgen Klopp prefers a 4-3-3 formation with four defenders, three central midfielders, and a forward line with a central striker flanked by two wide attackers. Center forward Roberto Firmino and left forward Sadio Mane combined for 44 goals and 22 assists between the Premier League and the Champions League, while Mohamed Salah matched that production almost by himself with 42 goals and 14 assists.Every one of these players was acquired in the transfer market: Firmino in 2015, Mane in 2016 and Salah last summer. Hitting on star attackers in three consecutive transfers is a major accomplishment no matter what your budget, but it’s especially impressive for Liverpool, which cannot afford to pay as much as the world’s richest clubs — as was made evident when Philippe Coutinho forced his way out of Liverpool for Barcelona in January. To build one of the world’s most dangerous front lines, Liverpool had to look for relative bargains, which more or less ruled out peak-age players at the height of their powers. Further, with Klopp’s pressing style, the team had to avoid the typical lumbering center forward and look for players versatile enough to press high and interchange in the attack. They needed attackers who could play anywhere in the front line. To find these key pieces, the team turned to analytics.One of the simplest ways to identify undervalued attackers is with expected goals (xG) and expected assists (xA) — two metrics that estimate the quality of scoring chances, built from information collected by sports-data company Opta.2The model for calculating expected goals seeks to give a single estimate for the likelihood of scoring a given shot, and the estimates for each shot are then added up over a season to give an expected goals total. You can find further methodological details in previous writeups. The ability to get on the end of good scoring chances, or to create them with a telling pass, is more stable across seasons than the ability to finish off such a chance. Over the last three years, very few young players have put up big numbers in xG and xA per 90 minutes while playing on smaller clubs and getting the majority of their minutes from outside the center forward role. Liverpool found three of them.

Liverpool, by using its resources smartly and developing more flexible tactics, put itself in position to take advantage of good fortune when it arrived.

Credit: Magee Sprague | For The LanternThe Ohio State men’s volleyball team (20-5, 11-3 MIVA) begins MIVA tournament play on Saturday against the Quincy Hawks (12-18, 0-14 MIVA) at St. John Arena. As an eight seed in the tournament, the Hawks were defeated handedly by the Buckeyes twice in the regular season, losing 3-0 in both matches. Though Quincy finished with 12 wins during the regular season, none of them came in conference play.Despite having many new players on the roster, head coach Pete Hanson said he was proud his team finishing first in the conference and clinching home-court advantage for both the quarterfinal and semifinal games.“We put ourselves in the position to host the playoffs here in Columbus as long as we keep winning,” Hanson said. “All the new faces that we put on the floor this year and having them come together and accomplish that is a pretty big thing.”Saturday night’s match will kick off tournament week, something senior outside hitter Maxime Hervoir said he’s looking forward to, even with all the outside stress of the Spring Semester winding down. “It’s the hardest part,” he said. “You have all the school stuff that is going on and at the same time the finals, the final papers, all that stuff, and you have to really handle everything at the same time—but that’s what makes it the best because it’s the most intense thing.”Hervoir said it’s important for the team to go back to what it has done all season.“It’s important to remember that if we are here it’s cause we deserve it and that we can actually win and remember our potential,” Hervoir said. “We are a good team, we’re a really good team—and also remember to play together because that’s how we’re going to win.”If the Buckeyes beat Quincy, they will play the winner of the Lewis and Fort Wayne quarterfinal matchup. Ball State, McKendree, Lindenwood and Loyola will be competing for a spot in the final on the other side of the bracket. Ohio State will take on Quincy in the MIVA quarterfinal at St. John Arena at 7 p.m. Saturday. read more
