(2019, January 16) retrieved 17 July 2019 from https://phys.org/news/2019-01-future-renault-ghosn-scandal.html Explore further Chief Operating Officer Thierry Bollore has temporarily taken over the top job at Renault, and would be a natural choice to replace Carlos Ghosn permanently © 2019 AFP Senard’s posting at the top of the tyre-making giant is coming to an end in May and he is well-liked by the French government, which with a 15 percent stake is Renault’s biggest shareholder. One plausible scenario would see him become chairman of the board, while Bollore would remain on as chief operating officer. PSA chief Carlos Tavares, whom Ghosn ousted from Renault in 2013 for daring to hint that he wanted to run the firm, is also being discussed as a possible successor.Several senior French officials have been dispatched to Tokyo for talks with Nissan chief Hiroto Saikawa, which could speed up the naming of Ghosn’s replacement. A change in leadership structure?Until his arrest Ghosn was simultaneously CEO of Renault and the alliance, as well as board chairman at Nissan and Mitsubishi.Several sources say his replacement at Renault will not necessary also lead the Renault-Nissan-Mitsubishi Alliance, which is based in the Netherlands. Renault board maintains Ghosn as CEO, says pay was legal Carlos Ghosn is widely viewed as having been the glue that kept the alliance together Tensions are also running high between Renault and its Japanese partners following the sensational allegations of financial misconduct against Ghosn.What lies ahead for Renault, a company which Ghosn grew into an industrial behemoth as part of the powerful alliance with Nissan and Mitsubishi?Who could replace Ghosn?Ghosn is still Renault’s CEO—but he needs to be replaced, with even his own lawyers acknowledging he could remain in jail awaiting trial for months. “It’s a foregone conclusion,” a source close to the matter told AFP.A former senior executive said Renault was “in the process of recruiting Ghosn’s replacement”, while a third source said: “There will be a replacement, we just need to be a little patient.”Thierry Bollore, Renault’s chief operating officer, has temporarily taken the reins and would be Ghosn’s natural heir.Choosing Bollore, a Frenchman with plenty of experience in Asia, would allow for some continuity in a company that has been badly rocked by the Ghosn affair.But several other names are also circulating, including Didier Leroy, executive vice president at Toyota, and Michelin CEO Jean-Dominique Senard. Behind bars in Japan, Carlos Ghosn has already been stripped of his leadership roles at Nissan and Mitsubishi—leaving questions for Renault, the third carmaker in their alliance, over who should steer the French company now. Can the alliance survive?Ghosn, accused of with breach of trust and under-declaring his income, had been seen as the glue binding together the complex three-way structure that makes up the world’s top-selling auto company. Nissan says the alleged financial misconduct came to light through a company whistleblower—a source of angst at Renault, which has denounced what it called a “deliberately orchestrated destabilisation campaign”.The documents passed to investigators have targeted figures close to Ghosn including Mouna Sepehri, Renault’s head of legal affairs and communications.Resentment has long been brewing in Japan over the structure of the alliance, which some say gives Renault an undue share of Nissan’s profits.Some within French company suspect Nissan of seeking to tip the balance of power within the alliance to the detriment of Renault, which currently holds 43 percent of its Japanese partner after saving it from collapse in the early 2000s.Nissan CEO Hiroto Saikawa dismissed this as “absurd”, saying: “Look at the evidence. It’s serious.”He insisted he was committed to the alliance and had no immediate plans to seek to change its structure.One Paris source suggested changes would be necessary in the top ranks of Nissan for the Franco-Japanese partnership, forged in 1999, to continue.Another source said it was inevitable that there would be “battles for influence” and “score-settling”, but insisted the alliance would live on to see another day. Renault is starting to consider replacing Carlos Ghosn, who remains in custody in Japan over allegations of financial misconduct Renault’s CEO job could even be split up between an executive general manager and board chairman, a structure used by other French companies partly owned by the state.One industry insider said it was “normal” for the recruitment process to take time, adding “the streets are not overflowing” with potential leaders of firms this large.French Finance Minister Bruno Le Maire stressed that “there is a pilot in the plane” in Ghosn’s absence in the form of Renault’s temporary leadership.

New algorithm for estimating body mass of extinct quadrupedal mammals

first_img Ever since humans discovered that there were creatures roaming the earth that had gone extinct, efforts have been made to try to imagine what they must have looked like. Skeletons have been reassembled and then estimates on body shape and mass were made based on how modern animals are put together—but such efforts have been deemed too open to interpretation, which likely meant that researchers were simply guessing. In an attempt to improve the accuracy, other researchers developed 3D computer models and simulations, but have had to acknowledge that there was still a lot of guesswork involved. Now, in an attempt to remove some of that guesswork, Brassey and Gardiner have developed a computer algorithm that takes advantage of the best aspects of both prior methods. Their algorithm allows for the creation of what they call “alpha-shapes” where objects meant to mimic actual body parts, are “shrink-wrapped” around a reconstructed virtual skeleton created from the actual bones of a real specimen. The algorithm also allows for fine-tuning the shrink wrapping process from very fine, to quite coarse—on an individual specimen. Once the rendering is done, the algorithm calculates the original body mass of the creature by using an average of the body mass of 14 modern animals.Brassey and Gardiner have tested their algorithm on the remains of a found wooly mammoth and a giant sloth—the first was calculated to be 3.6 metric tons, the second 3.7. They note that the reconstruction of the skeleton has a big impact on the final result, which means that in order to get an accurate body mass estimate, researchers must first put the skeleton together in the way that nature intended. More information: An advanced shape-fitting algorithm applied to quadrupedal mammals: improving volumetric mass estimates, Published 19 August 2015.DOI: 10.1098/rsos.150302AbstractBody mass is a fundamental physical property of an individual and has enormous bearing upon ecology and physiology. Generating reliable estimates for body mass is therefore a necessary step in many palaeontological studies. Whilst early reconstructions of mass in extinct species relied upon isolated skeletal elements, volumetric techniques are increasingly applied to fossils when skeletal completeness allows. We apply a new ‘alpha shapes’ (α-shapes) algorithm to volumetric mass estimation in quadrupedal mammals. α-shapes are defined by: (i) the underlying skeletal structure to which they are fitted; and (ii) the value α, determining the refinement of fit. For a given skeleton, a range of α-shapes may be fitted around the individual, spanning from very coarse to very fine. We fit α-shapes to three-dimensional models of extant mammals and calculate volumes, which are regressed against mass to generate predictive equations. Our optimal model is characterized by a high correlation coefficient and mean square error (r2=0.975, m.s.e.=0.025). When applied to the woolly mammoth (Mammuthus primigenius) and giant ground sloth (Megatherium americanum), we reconstruct masses of 3635 and 3706 kg, respectively. We consider α-shapes an improvement upon previous techniques as resulting volumes are less sensitive to uncertainties in skeletal reconstructions, and do not require manual separation of body segments from skeletons.

Derrick Rose steals the show LeBron Cavs take the game

The Cleveland Cavaliers and Chicago Bulls meet for an NBA preseason game Oct. 20 at the Schottenstein Center. Cleveland won, 107-98. Credit: Mark Batke / Photo editorEven though it wasn’t a regular season game, NBA action at the Schottenstein Center was in full swing as the Cleveland Cavaliers defeated the Chicago Bulls on Monday night, 107-98.The player many people undoubtedly came to see — Cavs forward LeBron James — did not disappoint as the Akron native totaled 18 points on 6-of-11 shooting to go along with seven rebounds and six assists in 32 minutes of play.James said playing in front of the Central Ohio crowd was special.“It was great, it was great to be here. It is great to have these fans and for us to put on a show for them,” James said.Cavaliers coach David Blatt said even though it was an exhibition game, he thought the matchup was played at a high level.“It’s no big thing, obviously this is just an exhibition game, but certainly a good level game for fans to see,” Blatt said. “We had a full crowd here in Columbus, and the people got their money’s worth and both teams played hard and played pretty well.”Get their money’s worth they did, as the Cavs weren’t the only ones putting on a show for the sellout crowd of 19,049.Bulls guard Derrick Rose, who has missed nearly two full seasons because of multiple knee injuries, exploded for 16 points in the second quarter, bringing the crowd at the Schottenstein to its feet multiple times. He totaled 30 points on 12-18 shooting for the game despite only playing 24 minutes.James said although Rose dissected the Cavs defense for most of the night, he was happy and unsurprised to see the former Memphis Tiger playing to his ability again.“I watched him all summer. Watched him in their practices when they were in Vegas, and I payed attention to him over the preseason,” James said. “As a league, as a fan, it is great to have him back and him playing at a high level.”Blatt said he agreed with his star forward and commented on how tough it is to stop Rose.“Do you have any ideas? I dont know what to do with that guy,” Blatt said following the game. “He is pretty good. As a basketball person, and as a lover of this sport, it was great to see him back.”Rose’s point-guard counterpart — the Cavaliers’ Kyrie Irving — also impressed, as the Duke product finished with a team-high 28 points on 10-of-19 shooting to go along with seven assists in 39 minutes of play.Cleveland newcomer and former Minnesota Timberwolves’ player Kevin Love struggled with his shot against the Bulls as he finished 2-for-10 from the field and was the only Cavaliers starter who didn’t score in double figures with just nine points to finish.Despite Love’s struggles, James said it was good to get extended minutes with Love and Irving for the first time during the preseason.“We have limited time on the floor, but I think tonight was a good example of what we can do,” James said. “That was the closest to 48 minutes we have played in the preseason. Kyrie played a great game, Kev’s shot was off a little bit, but I think he had a great game with 13 rebounds.”Cavaliers center Anderson Varejao picked up the slack as he came out firing on all cylinders in the first half. He scored 16 points on 8-of-10 shooting to help boost Cleveland to a 51-49 halftime lead. He finished with 22 points on the night.Blatt said following the game that he was pleased with how his team performed as a whole.“What I really liked obviously about tonight was that we had Kevin, Kyrie, LeBron on the floor at the same time,” Blatt said. “We got a fair view of that tonight, and I thought that went pretty well. Overall, I think the Cavaliers are taking strides in the correct direction.”The Cavaliers are set to play their preseason finale Wednesday against the Memphis Grizzlies at the FedExForum in Memphis before they are scheduled to begin their regular season at home Oct. 30 against the New York Knicks.
