Abstract

Super-resolution microscopy, or nanoscopy, enables the use of fluorescent-based molecular localization tools to study molecular structure at the nanoscale level in the intact cell, bridging the mesoscale gap to classical structural biology methodologies. Analysis of super-resolution data by artificial intelligence (AI), such as machine learning, offers tremendous potential for discovery of new biology, that, by definition, is not known and lacks ground truth. Herein, we describe the application of weakly supervised paradigms to super-resolution microscopy and its potential to enable the accelerated exploration of the nanoscale architecture of subcellular macromolecules and organelles., Comment: 26 pages, 4 figures

13. The energy method for high-order invariants in shallow water wave equations

Abstract

Third order dispersive evolution equations are widely adopted to model one-dimensional long waves and have extensive applications in fluid mechanics, plasma physics and nonlinear optics. Among them are the KdV equation, the Camassa--Holm equation and the Degasperis--Procesi equation. They share many common features such as complete integrability, Lax pairs and bi-Hamiltonian structure. In this paper we revisit high-order invariants for these three types of shallow water wave equations by the energy method in combination of a skew-adjoint operator $(1-\partial_{xx})^{-1}$. Several applications to seek high-order invariants of the Benjamin-Bona-Mahony equation, the regularized long wave equation and the Rosenau equation are also presented.

Abstract

For seeking the cause of the increase in dough water absorption rate after cold plasma treatment, this study adopted low-pressure, radiofrequency 120 W helium cold plasma (CP) to treat wheat flours from 0 s to 180 s. Results showed that water absorption rate, conductivity, values of water and sucrose solvent retention capacity (SRC), and paste breakdown value in wheat flours increased significantly with increasing CP treatment time. To further explore the change causes in these physiochemical indexes, we developed a seven- parameter polynomial , (M was equilibrium moisture (%), ERH was equilibrium relative humidity (decimal), t was temperature (℃), and A~G were parameters. This polynomial could fit moisture sorption isotherms (20-35 ℃ and ERH 10%-90%) of helium CP treated flours, and the goodness-of-fit indexes were superior to those of modified Chung-Pfost (commonly used) and four-parameter polynomial (without temperature term) equations. The seven-parameter polynomial equation clearly showed the hysteresis loops between moisture adsorption and desorption isotherms of flour samples, which shifted downward with increasing temperature. The hysteresis degree showed a parabolic shape curve with increasing ERH, and the vertex of the parabola was at the range of 40-50% ERH. CP treatment shifted the monolayer adsorption sites to multi-molecular adsorption sites ahead of schedule, from ERH 50% to 40%. Further analysis using Dent model showed that the helium CP treatment was able to reduce the mono-layer moisture content and spreading pressure in wheat flour, and increase the elasticity of a capillary wall. The ability of water molecules was increased to form hydrogen bonds with the chemical components, which promoted the uniform distribution and permeation of water molecules into flour particles. Infrared spectral scanning showed that the degree of short-range order at the surface of starch granules and the interaction between protein and starch tended to increase with increasing CP time. Helium cold plasma technology has potential application in improving flour processing quality.

Abstract

Commercial autonomous machines is a thriving sector, one that is likely the next ubiquitous computing platform, after Personal Computers (PC), cloud computing, and mobile computing. Nevertheless, a suitable computing substrate for autonomous machines is missing, and many companies are forced to develop ad hoc computing solutions that are neither principled nor extensible. By analyzing the demands of autonomous machine computing, this article proposes Dataflow Accelerator Architecture (DAA), a modern instantiation of the classic dataflow principle, that matches the characteristics of autonomous machine software., Comment: Please note that this may be a special case in that Professor Gao sadly passed away on September 12th, just as we had put the finishing touches on this submission
