Savannah River Tritium Enterprise has used LaNi4.25Al0.75 (LANA75) hydride beds to store hydrogen isotopes for over two decades. A benefit of using LANA75 is that the 3He generated from tritium dec...

introduction: spinal cord injury (sci) is one of the most serious clinical diseases, which not only affects the patient's physical and mental status, but its effects will be spread to family and community. after severe spinal cord injury, astrocytes of the central nervous system (cns) become reactive astrocytes, and play the main role of glial scar formation. the scar is a major obstacle t...

The goal of sparse recovery is to recover the (approximately) best k-sparse approximation x̂ of an n-dimensional vector x from linear measurements Ax of x. We consider a variant of the problem which takes into account partial knowledge about the signal. In particular, we focus on the scenario where, after the measurements are taken, we are given a set S of size s that is supposed to contain most...

Partial packet recovery protocols attempt to repair corrupted packets instead of retransmitting them in their entirety. Recent approaches have used physical layer confidence estimates or additional error detection codes embedded in each transmission to identify corrupt bits, or have applied forward error correction to repair without such explicit knowledge. In contrast to these approaches, our ...

Nielsen’s theorem indicates that a bipartite entangled pure state can be exactly converted into another pure one by local quantum operations and classical communication if and only if the Schmidt coefficient vector of the former is majorized by that of the latter [Phys. Rev. Lett. 83, 436 (1999)]. As a consequence of Nielsen’s majorization criterion, the quantity of entanglement is decreased du...

In this paper an error recovery mechanism for SRAM based FPGA systems is presented. Previous recovery methods employ processor cores as a reconfiguration controller consuming notable amount of device resources and introducing additional error detection and recovery latency. The described mechanism is controlled by a finite state machine architecture providing small hardware overhead and short r...

Six experiments used magazine approach in rat subjects to explore changes with time in responding for stimuli brought to a common moderate level of performance through acquisition or extinction. They found no evidence for increases with time in behavior during stimuli given simple acquisition. However, stimuli brought to that same level by reversal learning, repeated reversal, or partial reinfo...

The problem of community detection from noisy observations of interactions between individuals has important applications to diverse areas such as biology, sociology, and computer science. This problem is particularly interesting when the number of interactions is on the order of the size of the populations, that is the graph where two interacting individuals are connected by an edge is sparse....
