Using nonvolatile memories in memory hierarchy has been investigated to reduce its energy consumption because consume zero leakage power cells. One of the difficulties is, however, that endurance most technologies is much shorter than conventional SRAM and DRAM technology. This limited usage only low levels a hierarchy, e.g., disks, far from CPU.
Phase-change may enable continued scaling of main memories, but PCM has higher access latencies, incurs power costs, and wears out more quickly than DRAM. This article discusses how to mitigate these limitations through buffer sizing, row caching, write reduction, wear leveling, make a viable dream alternative for scalable memories.
The emerging Spin Torque Transfer memory (STT-RAM) is a promising candidate for future on-chip caches due to STT-RAM's high density, low leakage, long endurance and access speed. However, one of the major challenges STT-RAM its write current, which disadvantageous when used as an cache since dynamic power generated too high.
Psychological resilience may reduce the impact of psychological distress to some extent.

Enantiomerically pure sulfinimines (thiooxime S-oxides 10), important building blocks in the asymmetric synthesis of amine derivatives, are prepared good to excellent yields one step from aromatic, heteroaromatic, and aliphatic aldehydes. This protocol involves treating commercially available (R)- or (S)-menthyl p-toluenesufinate (Andersen reagent 4) with LiHMDS, followed by aldehyde, affording (E)-10 exclusively. The 10 formed via a Peterson-type olefination reaction silylsulfinamide anion...

Abstract Inspirited by the wide range of applications graphene and similarity between boron carbon, 2D sheets have gained extensive research interest. In this work, using first‐principles combined with a nonequilibrium Green's function method, thermal conductance fully hydrogenated borophene, named borophane, is studied. Interestingly in contrast to widely perceived sense, at 300 K, it found that borophane armchair direction remarkably larger than graphene. More interesting, dimensionality...
Strongly correlated systems exhibit intriguing properties caused by intertwined microscopic in- teractions that are hard to disentangle in equilibrium. Employing non-equilibrium time-resolved photoemission spectroscopy on the quasi-two-dimensional transition-metal dichalcogenide 1T-TaS$_2$, we identify a spectroscopic signature of double occupied sites (doublons) reflects fundamental Mott physics. Doublon-hole recombination is estimated occur time scales one electronic hopping cycle...
Supramolecular electronics provide an opportunity to introduce molecular assemblies into electronic devices through a combination of noncovalent interactions such as [π···π] and hydrogen-bonding interactions. The fidelity dynamics hold considerable promise when it comes building with controllable reproducible switching functions. Here, we demonstrate strategy for electronically robust switches by harnessing two different between couple pyridine derivatives. single-supermolecule switch is...
As memory-intensive applications continue to drive the need for advanced architectural solutions, Compute Express Link (CXL) has risen as a promising interconnect technology that enables seamless high-speed, low-latency communication between host processors and various peripheral devices. In this study, we explore application performance of ASIC CXL memory in data-center scenarios. We then further multiple potential impacts (e.g., throughput, latency, cost reduction) employing via carefully...
High-precision molecular manipulation techniques are used to control the distance between radical molecules on superconductors. Our results show that can host single electrons with a spin 1/2. By changing tip and sample, quantum phase transition from singlet doublet ground state be induced. Due local screening charge redistribution, we observe either charged or neutral molecules, which couple in sophisticated way, showing behavior deviates classical spins. Dimers at different separations...

Introduction In China, the severity of medical disputes has greatly increased during past two decades, which caused various adverse outcomes for health professionals. Previous research on violence in healthcare settings primarily examined occurrence patient-initiated and its effects physicians, but few studies have focused impact extent physicians' exposure to violence. This study different frequency levels specific types their relationships psychological wellbeing, including emotional...
Abstract Heat energy in solids is carried by phonons and electrons. However, most two-dimensional (2D) materials, the contribution from electrons to total thermal conduction much lower than that for phonons. In this work, through first-principles calculations combined with non-equilibrium Green’s function theory, we studied electron phonon conductance recently synthesized 2D hydrogen boride. The hexagonal boron network bridging atoms suggested exhibit comparable lattice (4.07 nWK −1 nm −2 )...

Heck reaction catalyzed by cobalt hollow nanospheres has been developed; the coupling of alkenes with aryl iodide or bromide in presence potassium carbonate provides corresponding products moderate to good yields, which reveals obvious advantages such as low-cost catalyst, ligand-free condition, recyclability catalyst and simple experimental operation.
Investigating how electrons propagate through a single molecule is one of the missions molecular electronics. Electrons, however, are also efficient catalysts for conducting radical reactions, property that often overlooked by chemists. Special attention should be paid to electron catalysis when interpreting single-molecule conductance results simple reason an unexpected reaction mediated or triggered might take place in junction. Here, we describe counterintuitive structure–property...
