一 | KINGSLAND, Ga. -- A man who spent more than 16 years in prison in Florida on a wrongful conviction was shot and killed Monday by a sheriff's deputy in Georgia during a traffic stop, authorities and representatives said.Leonard Allen Cure, 53, was identified by the Georgia Bureau of Investigation, which is reviewing the shooting.His death was confirmed by Seth Miller, executive director of the Innocence Project of Florida, which represented Cure in his exoneration case.Miller said he was devastated by the news, which he heard from Cure's family.“I can only imagine what it’s like to know your son is innocent and watch him be sentenced to life in prison, to be exonerated and ... then be told that once he’s been freed, he’s been shot dead," Miller said. "I can’t imagine as a parent what that feels like.”The Georgia Bureau of Investigation said a Camden County deputy pulled over a driver along Interstate 95 near the Georgia-Florida line and the driver got out of the car at the deputy’s request. He cooperated at first but became violent after he was told he was being arrested, a GBI news release said.The agency said preliminary information shows the deputy shocked the driver with a stun gun when he failed to obey commands, and the driver then began assaulting the deputy. The GBI said the deputy again tried using the stun gun and a baton to subdue him, then drew his gun and shot the driver when he continued to resist.The agency didn't say what prompted the deputy to pull over Cure's vehicle.Miller couldn't comment specifically on Cure's death but said he has represented dozens of people convicted of crimes who were later exonerated.“Even when they’re free, they always struggled with the concern, the fear that they’ll be convicted and incarcerated again for something they didn’t do,” he said.It is customary for Georgia law enforcement agencies to ask the GBI to investigate shootings involving officers. The agency said it will submit its findings to the district attorney for the coastal Brunswick Judicial Circuit, which includes Camden County.Cure was convicted of the 2003 armed robbery of a drug store in Florida's Dania Beach and sentenced to life in prison because he had previous convictions for robbery and other crimes.But the case had issues from the start and his conviction came from a second jury after the first one deadlocked. In 2020, the Broward State Attorney’s Office new Conviction Review Unit asked a judge to release Cure from prison. Broward’s conviction review team said it found “troubling” revelations that Cure had solid alibis that were previously disregarded and no physical evidence or solid witnesses to put him at the scene. An independent review panel of five local lawyers concurred with the findings.Cure was released that April after his sentenced was modified. That December, a judge vacated his conviction and sentence.“I’m looking forward to putting this situation behind me and moving on with my life,” Cure told the South Florida Sun Sentinel at the time. In June, Florida Gov. Ron DeSantis signed a claims bill granting Cure $817,000 in compensation for his conviction and imprisonment along with educational benefits.Miller said Cure, who lived in a suburb of Atlanta, received the money in August.“The Leonard we knew was a smart, funny and kind person,” Broward State Attorney Harold F. Pryor said in a statement to the Sun Sentinel Monday evening. “After he was freed and exonerated by our office, he visited prosecutors at our office and participated in training to help our staff do their jobs in the fairest and most thorough way possible. He would frequently call to check in on Assistant State Attorney Arielle Demby Berger, the head of the Conviction Review Unit, and offer our team encouragement to continue to do the important work of justice.”。北京时间1月16日，据外媒报道，每个人都知道达芬奇名画《蒙娜丽莎》中的女子似乎在回望观众的眼睛，无论观众在哪里看这幅画，蒙娜丽莎的眼睛似乎都在跟着自己。

二 | 但事实并非如此。蒙娜丽莎的眼睛实际上并不跟随周围的观察者。

三 | 一项新的研究发现，蒙娜丽莎的目光实际上落在观察者的右侧15.4度，远远超出了通常让你觉得有人在盯着我的角度。德国bilefield大学的知觉心理学家、该研究的作者Gernot Horstmann说：“她没有在看你。”不真实的“蒙娜丽莎效应”有点讽刺，因为肖像或照片中的人似乎跟随观察者的运动的现象被准确地称为“蒙娜丽莎效应”。霍斯曼说这种效应确实存在。

四 | 如果肖像或照片中的人直视前方，即使有人站在某个角度看照片，他或她也会感到肖像或照片中的人正盯着自己。只要观察者偏离不超过5度的角度，蒙娜丽莎效应就会发生。这对观众与屏幕人物的互动具有重要意义。如果你想让坐在房间右侧的观众感觉屏幕上的角色在看自己，不要让角色朝那个方向看，否则观众会觉得角色没有在看房间里的任何人。

五 | 为了达到这个效果，人们应该直视前方。Horstmann与合作作者Sebastian Loth一起研究了这种效应在创造人工智能“替代物”中的应用。在这个过程中，霍斯曼长时间地看着蒙娜丽莎，终于意识到了一个问题。”我意识到：“等一下，她没有盯着我看。为了确保这不是为了他们自己，研究人员让24名受试者在电脑屏幕上观看蒙娜丽莎的照片。他们在观看者和屏幕之间放置了一把尺子，让受试者指出尺子和蒙娜丽莎眼睛交叉处的数字。

六 | 为了测试照片中的其他元素是否影响观众对蒙娜丽莎眼睛的感知，研究人员放大了镜头。有时观众可以看到蒙娜丽莎的整个脸，有时只能看到眼睛和鼻子。另外，为了计算蒙娜丽莎眼睛的角度，研究人员在实验中途改变了尺子和屏幕之间的距离。这样就可以得到两个交点，从而计算出角度。《蒙娜丽莎》的研究结果表明，所有受试者都认为《蒙娜丽莎》中的人物并不是直接看自己，而是稍微看自己的右边。
