Ballistic performances of the hourglass lattice sandwich structures under high-velocity fragments

open access: yesDefence Technology
In this paper, the numerical simulation method is used to study the ballistic performances of hourglass lattice sandwich structures with the same mass under the vertical incidence of fragments. Attention is paid to elucidating the influences of rod cross-

Analytical model of nanowire FETs in a partially ballistic or dissipative transport regime

open access: yes, 2009
The intermediate transport regime in nanoscale transistors between the fully ballistic case and the quasi equilibrium case described by the drift-diffusion model is still an open modeling issue.

Hybrid Convolutional Neural Network‐Analytical Model for Prediction of Line Edge Roughness‐Induced Performance Variations in Fin‐Shaped Field‐Effect Transistor Devices and SRAM

open access: yesAdvanced Intelligent Systems, EarlyView.
This work presents a hybrid model for predicting the electrical characteristics of fin‐shaped field‐effect transistor devices and SRAM with line edge roughness. The model consists of a convolutional neural network (CNN) and an analytical model that simulates the electrical characteristics of transistors using the outputs of CNN, enabling fast and ...

Dirac fermion reflector by ballistic graphene sawtooth-shaped npn junctions

open access: yes, 2017
We have realized a Dirac fermion reflector in graphene by controlling the ballistic carrier trajectory in a sawtooth-shaped npn junction. When the carrier density in the inner p-region is much larger than that in the outer n-regions, the first straight ...

Phasentrennung von Nukleinsäuren: Mechanismen, Eigenschaften und Anwendungen

open access: yesAngewandte Chemie, EarlyView.
Jüngste Entdeckungen zeigen, dass einzelsträngige langkettige Nukleinsäuren temperaturinduziert phasentrennen und dabei mikrometergroße Kondensate bilden. Dieser Minireview fasst das aktuelle mechanistische Verständnis dieses Phänomens zusammen, beschreibt Strategien zur gezielten Kontrolle der physikalischen und chemischen Eigenschaften der Kondensate

Inhomogeneous Cooling of the Rough Granular Gas in Two Dimensions

open access: yes, 2014
We study the inhomogeneous clustered regime of a freely cooling granular gas of rough particles in two dimensions using large-scale event driven simulations and scaling arguments. During collisions, rough particles dissipate energy in both the normal and

Phase Separation of Nucleic Acids: Mechanisms, Properties, and Applications

open access: yesAngewandte Chemie International Edition, EarlyView.
Recent discoveries have shown that single‐stranded long‐chain nucleic acids can undergo temperature‐induced phase separation, enabling formation of micrometer‐sized condensates. This Minireview discusses the current mechanistic understanding of this phenomenon, highlights strategies for controlling the physical and chemical properties of these ...

Implementation of MPMM ballistic model for calculation of differential coefficients for TFTs according to NATO STANAG 4119 1

open access: yesStrategos, 2021
MPMM ballistic model (modified point mass model) is used to calculate all necessary ballistic trajectory elements (range, time of flight, angle of fall, maximum ordinate, differential coefficients, etc.) for classical spin-stabilized artillery projectiles.
