It was April 1968 and Baltimore was ablaze. Revered civil rights leader the Rev. Dr. Martin Luther King Jr. was dead, killed by an assassin’s bullet on April 4, and the city’s Black residents released their anger in a flood of looting, vandalism and fire.Into that maelstrom, an unlikely hero stepped up to stem the tide of unrest—notorious drug kingpin Melvin Williams.“Little Melvin (as he was best known) had talked to some of the guys to come together,” Clarence Mitchell recalled in an April 2008 AFRO article. “The hustlers of the day came from East Baltimore, they came from South Baltimore and they came from West Baltimore and they made appeals to the communities that they came from to stop the riots. The next day the riots had stopped.”The incident would become another highpoint in the urban legend of Little Melvin, a saga that ended Dec. 3, when he died at the age of 73 at the University of Maryland Medical Center. Friends said he suffered from cancer, The Baltimore Sun reported.Williams was known as the heroin king of Baltimore, who amassed a fortune while building a drug enterprise that stretched across West Baltimore in the 1960s. His rise to infamy inspired HBO’s “The Wire” and was chronicled in documentaries such as the BET series “American Gangster.”“Melvin Williams is a Baltimore 20th century legend,” said the Rev. Frank Reid III, pastor of Bethel AME Church in Baltimore, on “American Gangster.”Born in Baltimore’s City Hospital on Dec. 14, 1941, Williams was raised by his parents, a cab driver and nurse’s aide, on Madison Avenue. He attended Garnet Elementary School but dropped out of high school in the 11th grade.By that time, the boy with a genius I.Q. had already proven to be a prodigy in the gambling dens that littered Pennsylvania Avenue during its hey-day, winning thousands from gang members and crime bosses by the time he was 12, according to several documentaries. He then transitioned to a full life of crime under the auspices of Jewish gangster Julius Salisbury.By the time Williams was 15, he was already a millionaire, according to “Life in the Game,” a documentary on his life. In a 2012 video posted on YouTube, Williams claimed he had sold more than $1 billion worth of narcotics in his lifetime. And, at one time, his criminal organization was responsible for more than 25 percent of all murders in Baltimore, according to a 1987 newspaper series by David Simon, the creator of “The Wire.”Williams was known for running a sophisticated enterprise. He himself cast a dapper figure. For example, for his 11th court appearance in his much delayed trial for drug and weapons charges stemming from a March 8, 1967 incident, the AFRO described Williams as wearing a “smartly tailored black summer suit and a rose-colored shirt and pink, beige, black and blue striped tie.”Despite his smarts, however, he was not able to elude the law.“I consider you a big fish in the nefarious traffic of slow death,” Criminal Court Judge Anselm Sodaro told Williams in a July 1968 court appearance, before sentencing him to 12 years in prison for possession of narcotics, selling heroin and possession of a firearm in the March 1967 incident.At the time, Williams told the AFRO he was framed by a narcotics detective known for previously perjuring himself.Baltimore police officer Edward Burns—who would later become a writer for “The Wire,”—was able to conduct a successful investigation against, Williams, however. According to a Dec. 1, 1984 AFRO article, Williams was arrested when federal and state law enforcement conducted a raid of his Park Avenue “fortress” and seized guns, $54,000 Bugatti car, $250,000 worth of diamonds, furs and other jewelry and almost $300,000 in cash. The drug kingpin spent several years in prison, and was released in 2003.Williams emerged a different man after “finding God,” in prison, according to The Sun. “Sometime in my fifties I became aware that there was a God in charge, and not a Melvin,” he was cited as saying in a 2003 court appearance before U.S. District Judge Marvin J. Garbis.Several persons, including Rev. Reid whose church Williams attended, said the reformed criminal spent his later years counselling gang members and other young people about staying away from drugs and violence and otherwise tried to uplift his community.Williams is survived by his wife, Mary Williams; and two daughters.‘Little Melvin’ Hires High-Powered Team of Lawyers While in The Pen’ (May 20, 1968)“‘Little Melvin’ Machine Gun Case Set for Sept. 9” (August 10, 1968)Feds Get ‘Lil’ Melvin’s $54,000 car, $250,000 Worth of Diamonds and Furs’ (December 1, 1984)He Could Get Put Away for 38 Years (January 1, 1985)
Citation: Making Quantum Behavior Observable Using Optical Levitation (2010, January 26) retrieved 18 August 2019 from https://phys.org/news/2010-01-quantum-behavior-optical-levitation.html Physicists propose quantum entanglement for motion of microscopic objects In the new study, Chang and his coauthors have proposed a novel approach in which one isolates the system from the environment to such a degree that re-heating becomes a very inefficient process, even when the environment sits at room temperature. In this scheme, isolation is achieved by optically levitating an entire nano-mechanical system inside an optical cavity, which removes direct contact of the system with any other material. An optical cavity consists of an arrangement of mirrors that confines light inside of it by repeatedly reflecting the light waves off the mirrors. The force from the light is powerful enough to counteract the force of gravity, creating an optical trap that can suspend small, light-weight objects inside the cavity.The researchers calculated that an optically levitated silica nanosphere can be optically self-cooled to its ground state starting from room temperature. In this scenario, the nanosphere would interact with two optical modes of the cavity. One mode would provide an optical trap for the sphere, while a second, weaker mode would provide a radiation pressure cooling force. The scientists explain that this system is an extreme example of environmental isolation in which the nanosphere is mechanically isolated as well as thermally decoupled from its surroundings. In fact, the isolation is so good that quantum mechanical effects should be able to persist for times much longer than in conventional nano-mechanical systems, even those in cryogenic environments. While ground-state cooling should also be achievable in the near future with other systems, the scientists believe that the levitated system is an elegant example of how quantum effects can emerge and be robust even at room temperature. For example, the scientists predict that quantum entanglement initially shared between two light modes could be transferred onto the motion of two nanospheres trapped in separate cavities, which could then be observed. Other potential applications include exploring fundamental material limits, investigating nanoscale properties, and realizing novel quantum hybrid architectures.“There are a number of potential applications for quantum opto-mechanical systems,” Chang said. “One can imagine coupling such systems to other quantum systems to enable tasks such as quantum information transfer or quantum state manipulation. For example, work along these lines has been done by Dan Rugar at IBM, who has pioneered techniques to detect single electron spins in solid-state environments using opto-mechanics. It is also possible that opto-mechanical systems can be used as a novel platform for realizing nonlinear optical processes, by suitable manipulation of the interaction between light and mechanical motion.” Explore further The researchers, Darrick E. Chang, et al., from institutions in the US and Austria, are publishing their study in an upcoming issue of the Proceedings of the National Academy of Sciences. A similar proposal has simultaneously been put forth by researchers at the Max Planck Institute in Garching, Germany.“Over the next several years, there will be a concerted effort by a number of groups worldwide to observe and manipulate quantum behavior in progressively larger and more complex mechanical systems,” Chang, from the California Institute of Technology, told PhysOrg.com. “A major obstacle is the interaction between these systems and their environments, which tends to ‘leak away’ the quantum nature of these systems and return them to classical states. We’ve proposed a technique that can allow these interactions to be dramatically suppressed, by using optical forces to levitate such systems and remove them from any direct contact with material surroundings. We have shown in detail that this enables quantum behavior to emerge in the case of a levitated nanosphere, but we anticipate that these ideas can also be applied to a wide class of other systems and over a large range of system size scales.”As the scientists explain, in order to make a system’s quantum behavior observable, the system must be actively cooled to temperatures much colder than the surrounding environment. A key challenge to this cooling is overcoming the tendency of the environment to re-heat the system back to the ambient temperature. One possible solution is to work in cryogenic environments where the ambient temperature itself is reduced, an approach that is being taken by a number of groups worldwide. “Using cryogenic setups is certainly a viable approach to reduce the effects of the environment,” Chang said. “As one attempts to observe more exotic quantum effects and use larger systems, however, it is likely that moving to cryogenic environments alone will not be sufficient. This motivates the search for other techniques to suppress environmental interactions, which can be applied as an alternative or in conjunction with cryogenics.” This document is subject to copyright.

Chang, et al. (PhysOrg.com) — Perhaps one of the biggest challenges of modern physics is figuring out how to realize and take advantage of strange quantum behaviors in progressively larger and more complex systems. Progress along this front is expected to shed insight into the nature of quantum mechanics and lead to many novel applications. With this goal in mind, scientists have recently proposed a unique approach that involves optically levitating a nano-mechanical system in order to cool it to its quantum ground state, where the amount of motion of the system reaches the fundamental minimum set by intrinsic quantum fluctuations.
Register Now » While medical injections are unpleasant and inconvenient, they’re also necessary for people with illnesses like diabetes. But that might not be true for too much longer.Carl Schoellhammer, 28, has created a pill that would render syringes unnecessary. A graduate student at MIT, he recently won $15,000 at the Lemelson-MIT National Collegiate Student Prize in the health-care category. “When I received the phone call [telling me I’d won], I made them tell me three times to make sure I wasn’t dreaming,” he says.His prize-winning innovation is the Microneedle Pill (mPill), an ingestible capsule covered in microneedles — that is, needles so small that they’re measured in microns. The pill allows drugs that are typically injected to be delivered directly into the gastrointestinal tract.Image credit: Lemelson-MIT Program.Related: Google’s Next Goal: Trying to Improve Robot-Assisted Surgery“The GI tract is a dense network of blood capillaries,” Schoellhammer explains. “The outer layer is a bit of a barrier so the needles are a nice way to introduce a drug into the tissue and then it diffuses and you get systemic delivery.” In layman’s terms: the drug gets into your system faster than it would if administered via injection.Although an image of the pill that was used in testing might remind people of a cactus or a porcupine, the plan is for the pill to be smaller and coated when it hits the market. The coating will dissolve in stomach acid, freeing the needles to introduce the medicine. Once the drugs are delivered, the capsule can pass through the body safely. In the future, though, Schoellhammer hopes he can create the needles out of crystallized sugar.The mPill took an estimated three years to go from concept to prototype, and it’ll be approximately another three to five years before the product is on the market. In the meantime, the innovation has garnered attention. Schoellhammer says that he’s in talks with with a few pharmaceutical companies about the mPill, and he hopes to market it as a diagnostic technology that can be used for a wide range of injections such as insulin and growth hormones. As it turns out, pharmaceutical giant Novartis announced this week that it’s testing similar technology through a collaboration with a startup called Rani Therapeutics.Related: The 10 Most Influential Leaders in Tech Right NowNeedle-covered pills aren’t the only thing up Schoellhammer’s sleeve. He’s working on the Ultrasound Probe (uProbe), a handheld device inserted suppository-style that uses ultrasound waves to push medicine into the tissues of the GI tract. This allows the body to absorb the medicine faster. Image credit: Lemelson-MIT Program.Schoellhammer sees this being helpful for the 1 million people in the United States who have irritable bowel syndrome (IBS) as well as other conditions. While he wants to advance the uProbe further and conduct more animal testing, he estimates the product can be on the market in five years.This is a lot of information to digest, but don’t worry — this brilliant scientist is probably already working on a way to make it easier.Related: Meet Amelia, the AI Platform That Could Change the Future of IT 3 min read June 1, 2015 Free Webinar | Sept 5: Tips and Tools for Making Progress Toward Important Goals Attend this free webinar and learn how you can maximize efficiency while getting the most critical things done right.
