Unlocking Strength‐Toughness Dilemma in High‐Entropy Borides by Intragranular Microstructural Reconstruction

Advanced Science, EarlyView.
An extreme non‐equilibrium process combining heavy direct current sintering and TiSi2 addition is used to construct intragranular energy dissipation units within high‐entropy boride ceramics to overcome the strength‐toughness trade‐off. The resulting ceramic demonstrates attractive mechanical properties with a flexural strength of 887 MPa and a ...

Fault Tolerance in Multicore Clusters. Techniques to Balance Performance andDependability

Journal of Computer Science and Technology, 2016
In High Performance Computing (HPC) the demand for more performance is satisfied by increasing the number of components. With the growing scale of HPC applications has came an increase in the number of interruptions as a consequence of hardware failures.

Nanopore‐Based Protein Deceleration and Sensing Using Graphene/Si3N4 Dual Membrane Cavity

Advanced Science, EarlyView.
A graphene/Si3N4 dual membrane cavity system achieves multi‐stage protein deceleration through spatial geometry. Multi‐level current traces provide high‐resolution spatial localization and early warning signals. ABSTRACT Sequencing of protein with nanopores has emerged as a powerful tool offering rapid readout, high accuracy, low cost, and portability.

Parallel Application Signature for Performance Prediction

Journal of Computer Science and Technology, 2010
In order to measure the performance of a parallel machine, a set of application kernels as benchmarks have often been used. However, it is not always possible to characterize the performance using only benchmarks, given the fact that each one usually ...

HLA‐DR+ Schwann Cells Generate the Protumor Cancer‐Neuron‐Immune Niche in Head and Neck Squamous Cell Carcinoma

Advanced Science, EarlyView.
Hijacked and educated by HNSCC cells, HLA‐DR+ Schwann cells lost their normal neural‐related functions but acquired immunoregulatory phenotypes to promote CD4+ T cells transform into Tregs. HLA‐DR+ Schwann cells induced a macrophage subpopulation, Il1β.

On the Nature of Cao Cao’s Appointments of the Provincial Officials

Vestnik NSU. Series: History and Philology, 2019
Later Han 後漢 termination in the 220 AD was a result of multiple crises, one aspect of which had been the political bankruptcy of the emperor and his loyalists. A turbulent and war-torn period, which started from the rebellion of the Yellow Turbans in 184 AD, has been a topic of discussion for many years ever since the Jin 晉empire.

Study on the Reaction Mechanism of RuOx and Its Enhanced Hydrogen Evolution Reaction Activity

Advanced Science, EarlyView.
In situ Raman spectroscopy and DFT calculations reveal that, prior to the onset of HER, the surface of RuOx undergoes reversible reduction and structural reconstruction. The resulting Ru(II)O/Ru(IV)O2 configuration is identified as the true catalytically active species.

An exciting Approach to Theoretical Spectroscopy

Advanced Science, EarlyView.
ABSTRACT Theoretical spectroscopy, and more generally, electronic‐structure theory, are powerful concepts for describing the complex many‐body interactions in materials. They cover methods from ground‐state properties to lattice excitations and light‐matter interaction, including time‐resolved variants.

High‐Performance Multi‐Walled Carbon Nanotubes‐Organic Passivated Si Solar Cells Enabled by Spatially Selective Harvesting of High‐Quality Sponges

Advanced Science, EarlyView.
Our work achieves an efficiency breakthrough in MWCNTs/Si solar cells by screening high‐quality pristine MWCNTs without any separation or purification processes. This breakthrough is mainly attributed to the excellent dispersibility of Nafion and the excellent hole transport property of MWCNTs:Nafion film containing charge transfer doping, passivation,
