Many recent works have designed accelerators for Convolutional Neural Networks (CNNs). While digital accelerators have relied on near data processing, analog accelerators have further reduced data movement by performing in-situ computation. Recent works take advantage of highly parallel analog in-situ computation in memristor crossbars to accelerate the many vector-matrix multiplication operati...

Causality on the gravity side of the AdS/CFT correspondence restricts motion on the moduli space of the N = 4 super Yang Mills theory by imposing a speed limit on how fast the scalar field may roll. This effect can be traced to higher derivative operators arising from integrating out light degrees of freedom near the origin. In the strong coupling limit of the theory, the dynamics is well appro...

During the acceleration of anomalous cosmic rays (ACRs) some singly-charged ions are stripped of additional electrons. The resulting multiply-charged ions are accelerated more efficiently, and most ACRs with ≥30 MeV/nuc are multiply-charged. This paper considers some implications of multiply-charged ACRs, including limits that they place on the time scales for ACR acceleration and transport, an...

The limits imposed on diffusive shock acceleration by upstream ion-neutral Alfvén wave damping, and by ionisa-tion and Coulomb losses of low energy particles, are calculated. Analytic solutions are given for the steady upstream wave ex-citation problem with ion-neutral damping and the resulting escaping upstream flux calculated. The time dependent problem is discussed and numerical solutions pr...

Psychophysical studies have demonstrated that humans are less sensitive to image acceleration than to image speed (e.g., Gottsdanker, 1956; Werkhoven, Snippe, & Toet, 1992). Because there is evidence that a common motion-processing stage subserves perception and pursuit (e.g., Watamaniuk & Heinen, 1999), either pursuit should be similarly impaired in discriminating acceleration or it must recei...

Lifetime prediction of polymers requires accelerated ageing based on an increase in UV light intensity and temperature. However, the representativeness artificial is still issue. The relevance highly UV-induced weathering raises question reciprocity failure depending polymer. influences irradiance temperature photooxidation kinetics polyethylene were studied to determine extent which increasing...

Based on MAGIC observations from June and July 2007, we present upper limits to the E > 140 GeV emission from the globular cluster M13. Those limits allow us to constrain the population of millisecond pulsars within M13 and to test models for acceleration of leptons inside their magnetospheres and/or surrounding. We conclude that in M13 either millisecond pulsars are fewer than expected or they...

The brain's ability to synchronize movements with external cues is used daily, yet neuroscience is far from a full understanding of the brain mechanisms that facilitate and set behavioral limits on these sequential performances. This functional magnetic resonance imaging (fMRI) study was designed to help understand the neural basis of behavioral performance differences on a synchronizing moveme...
