While significant progress has been made separately on analytics systems for scalable stochastic gradient descent (SGD) and private SGD, none of the major frameworks have incorporated differentially SGD. There are two inter-related issues this disconnect between research practice: (1) low model accuracy due to added noise guarantee privacy, (2) high development runtime overhead algorithms. This paper takes a first step remedy proposes SGD algorithm address both in an integrated manner. In...
Stress can affect people’s judgment and make them take risky decisions. Abnormal decision-making behavior is a core symptom of psychiatric disorders, such as anxiety, depression, substance abuse. However, the neuronal mechanisms underlying impairments are largely unknown. The anterior insular cortex (AIC) crucial structure to integrate sensory information with emotional motivational states. These properties suggest that AIC influence subjective prediction in decision-making. In this study,...
Data compression is a popular technique for improving the efficiency of data processing workloads such as SQL queries and more recently, machine learning (ML) with classical batch gradient methods. But efficacy ideas mini-batch stochastic descent (MGD), arguably workhorse algorithm modern ML, an open question. MGD's unique access pattern renders prior art, including those designed methods, less effective. We fill this crucial research gap by proposing new lossless scheme we call...
In this paper, we present a metasurface composed of complementary units that can realize orthogonal linear and linear-to-circular polarization conversion in multi-band. Linear has seven high-conversion frequency bands: 9.1–9.7 GHz, 15.6–17.6 19.4–19.7 21.2–23.1 23.5–23.8 26.2 27.9 GHz. Linear-to-circular also bands with axial ratios (ARs) less than 3 dB: 8.9–9.0 9.9–14.7 19.1–19.3 23.2–23.35 23.4 24.1–25.4 27.2–27.8 the generation multiple extended by combination units. Then, utilize...
To explore the effect of added graphene sheets (GNs) and perylene-3,4,9,10-tetracarboxylic dianhydride (PTCDA) on tribological mechanical performances polyimide (PI) matrix, GNs PTCDA reinforced PI-based composites were synthesized via blending method. The properties GNs/PTCDA/PI (GAPI) with different weight ratios under dry sliding, deionized water lubrication, kerosene lubrication comparatively investigated. A synergism was found between PTCDA; this endowed filled PI a lower friction...

There are two inter-related issues this disconnect between research practice: (1) low model accuracy due to added noise guarantee privacy, (2) high development runtime overhead algorithms. This paper takes a first step remedy proposes SGD algorithm address \emph{both} in an integrated...
Three units consisting of five, nine, and one square patches are used to construct a phase gradient metasurface with 2π distribution within 18.0-28.0 GHz. The three arranged in one-dimensional (1D) two-dimensional (2D) directions can precisely control the reflection beam direction plane gradient. Rotating 1D 2D convert single reflected wave into multi-angle low-energy beams, forming radar cross section (RCS) reduction metasurface. Using 16×16 periodic units, 10 dB RCS 18.0-25.5 GHz is achieved.
Stroke Therapy In article number 2203431, Xiaoling Gao, He Wang, Jun Chen, and co-workers engineer mesenchymal stem cells (MSCs) with near-infrared (NIR) magnetic resonance (MR) dual-modal tracking nanoparticles via a bioorthogonal method. An antioxidant layer covered on the MSCs' surface enhances their vitality in harsh stroke microenvironment. The vitality-enhanced MSCs remigrate from penumbra to infarct core act just like firemen struggling fire save lives.
