In these studies, 'whole-brain' refers to gray matter regions only, which is the only tissue traditionally studied with fMRI. However, recent reports have also demonstrated reliable detection and analyses of BOLD signals in white matter which have been largely ignored in previous reports. Here, using model-free analysis and simple tasks, we investigate BOLD signal changes in both white and gray matters. We aimed to evaluate whether white matter also displays time-locked BOLD signals across all structural pathways in response to a stimulus. We find that both white and gray matter show time-locked activations across the whole-brain, with a majority of both tissue types showing statistically significant signal changes for all task stimuli investigated. We observed a wide range of signal responses to tasks, with different regions showing very different BOLD signal changes to the same task. Moreover, we find that each region may display different BOLD responses to different stimuli. Overall, we present compelling evidence that the whole brain, including both white and gray matter, show time-locked activation to multiple stimuli, not only challenging the idea of sparse functional localization, but also the prevailing wisdom of treating white matter BOLD signals as artefacts to be removed.</div><div></div><div></div><div></div><div></div><div></div><div>A Matter of Time hd full movie download</div><div></div><div>Download File:

The big breakthrough, he argues, is less that these particular crystals repeat in time than that they are the first of a large class of new materials that are intrinsically out of equilibrium, unable to settle down to the motionless equilibrium of, for example, a diamond or ruby.</div><div></div><div></div><div>While Yao is hard put to imagine a use for a time crystal, other proposed phases of non-equilibrium matter theoretically hold promise as nearly perfect memories and may be useful in quantum computers.</div><div></div><div></div><div>An ytterbium chain</div><div></div><div></div><div></div><div>The time crystal created by Chris Monroe and his colleagues at the University of Maryland employs a conga line of 10 ytterbium ions whose electron spins interact, similar to the qubit systems being tested as quantum computers. To keep the ions out of equilibrium, the researchers alternately hit them with one laser to create an effective magnetic field and a second laser to partially flip the spins of the atoms, repeating the sequence many times. Because the spins interacted, the atoms settled into a stable, repetitive pattern of spin flipping that defines a crystal.</div><div></div><div></div><div>From the perspective of quantum mechanics, electrons can form crystals that do not match the underlying spatial translation symmetry of the orderly, three-dimensional array of atoms, Yao said. This breaks the symmetry of the material and leads to unique and stable properties we define as a crystal.</div><div></div><div></div><div>A time crystal breaks time symmetry. In this particular case, the magnetic field and laser periodically driving the ytterbium atoms produce a repetition in the system at twice the period of the drivers, something that would not occur in a normal system.</div><div></div><div></div><div>Yao worked closely with Monroe as his Maryland team made the new material, helping them focus on the important properties to measure to confirm that the material was in fact a stable or rigid time crystal. Yao also described how the time crystal would change phase, like an ice cube melting, under different magnetic fields and laser pulsing.</div><div></div><div></div><div></div><div></div><div></div><div></div><div>A Matter of Time is a 1976 American-Italian semi-musical fantasy film starring Liza Minnelli and Ingrid Bergman, directed by Vincente Minnelli. The screenplay, by John Gay, is based on the novel The Film of Memory (La Volupt d'tre) by Maurice Druon. The fictional story is based loosely on the real life exploits of the infamous Italian eccentric, the Marchesa Casati, whom Druon knew during her declining years in London while he was stationed there during World War II. The film marked the first screen appearance for Isabella Rossellini, the last for Charles Boyer, and it proved to be Vincente Minnelli's final project.[3]</div><div></div><div></div><div>At a mid-1950s press conference, scenes are shown for an upcoming film starring Nina, a popular screen celebrity. While on her way to the conference, Nina looks at herself in an ornate mirror, which triggers a flashback to her arrival in Rome, when she was 19 years old. Her cousin, Valentina, has arranged for her to work as a chambermaid in a dilapidated hotel.</div><div></div><div></div><div>In the course of her duties, Nina meets an ailing Signora Contessa Sanziani, who was once the toast of Europe. The Contessa receives a visit from her husband, Count Sanziani, from whom she has been estranged for 40 years. Old quarrels are revived and Sanziani leaves the hotel, telling the manager that he does not wish to be informed if anything should happen to his wife.</div><div></div><div></div><div>After having a discussion with Nina, the Contessa decides to take her under her wing and turn her into a sophisticated woman. One evening, the Contessa summons Nina to her room and shows her a sari an Indian ambassador had once given her.</div><div></div><div></div><div>She insists that Nina undress and places the sari on her. The Contessa then gives Nina a haircut and puts makeup on her. Now looking nothing like a maid, Nina imagines herself living out the Contessa's existence while listening to her stories. This triggers a series of fantasy sequences, all taking place in elaborate settings such as casinos and Venetian palazzos.</div><div></div><div></div><div>On a rare day off from work, Nina explores Rome and begins to sense the bright future that may lie in store for her. That evening, while she is performing a task for the Contessa, the latter suffers a mental breakdown. The hotel's manager, angered by the Contessa's wailing, insists that she must leave the hotel within a few days.</div><div></div><div></div><div>The next morning, Nina seeks help from Mario, a frustrated screenwriter who lives in the hotel. She has brought with her some of the Contessa's old stock certificates, hoping that Mario can determine their worth. Mario says they are worthless, but feels no pity for the Contessa. Angered, Nina leaves his room.</div><div></div><div></div><div>She uses part of this money to help pay the Contessa's hotel expenses. That same day, Nina goes to a restaurant to pick up the Contessa's dinner. A screen director, Antonio Vicari, sees Nina there and uses Mario, who is writing a screenplay for him, to meet her. Eventually, arrangements are made for Nina to have a screen test.</div><div></div><div></div><div>Before she leaves for the studio, she finds that the Contessa has checked out of the hotel to find an old flame, Gabriele d'Orazio. No longer thinking clearly, the Contessa hurries into the street and is hit by a car. She is taken, unconscious, to a Catholic charity hospital.</div><div></div><div></div><div>Meanwhile, Nina has difficulties with her screen test, until Mario gets her to talk about the Contessa. Her subsequent show of passion impresses Vicari, who decides he wants Nina to star in his next picture.</div><div></div><div></div><div>Nina hurries off the set, and after a search, she and Mario locate the hospital where the Contessa is under the care of Sister Pia. Nina is taken to the Contessa's bedside, who has just died. Saddened, Nina takes the Contessa's ornate mirror as a remembrance and leaves the hospital.</div><div></div><div></div><div>Back at the present time, Nina has become a motion picture star. She arrives at the press conference. As she steps out of her limousine, a girl hurries up and says she wants to be just like Nina when she grows up.</div><div></div><div></div><div>The novel had been adapted for the stage by Paul Osborne as La Contessa in 1965 and starred Vivien Leigh in the title role. Minnelli read the book in 1966, but only obtained the film rights in 1973. He raised the funds via Jack H. Skirball, a sometime producer. Eventually American International Pictures agreed to co-finance with Italian producer Giulio Sbarigia.[4]</div><div></div><div></div><div>Cost-conscious American International Pictures executives, dismayed by filming delays and rising expenses, wrested control of the film from Vincente Minnelli.[5] Liza Minnelli's then husband Jack Haley Jr. re-cut the film to 97 minutes. Vincente Minnelli later disowned it, and fellow director Martin Scorsese took out ads in the trade papers chastizing AIP for its treatment of the screen legend.[4]</div><div></div><div></div><div>John Kander and Fred Ebb wrote "The Me I Haven't Met Yet" and the title tune. "Do It Again" by George Gershwin and Buddy G. DeSylva also was heard in the film, performed by Nina (Liza Minnelli) in the ballroom of a Venetian palazzo.</div><div></div><div></div><div>In his review in The New York Times, Vincent Canby wrote "It is full of glittery costumes and spectacular props. It is performed by talented, sophisticated people who adopt the faux-naif gestures of an earlier show-biz tradition, and though it is expensive, it sounds peculiarly tacky...the film has the air of an operetta from which the music has been removed. It's even acted that way...Because A Matter of Time has moments of real visual beauty, and because what the characters say to each other is mostly dumb, it may be a film to attend while wearing your earplugs."[6]</div><div></div><div></div><div>In Time, Jay Cocks wrote "It makes for an awkward occasion: a group of gifted people working so far below their best talents that everything takes on the giddy air of a runaway charade...the movie could have worked with hard effort and a little magic, but something has gone terribly wrong. Director Minnelli's once wondrous alchemy turns everything to lead. The movie is disjointed, sappy, hysterical; and the actors, perhaps sensing trouble, press on with painful, overbearing desperation...A Matter of Time does not look at all like a Minnelli movie. The fastidious craftsmanship that he has through the years expended even on the lowliest undertaking is nowhere in evidence."[8]</div><div></div><div> 795a8134c1</div>
