Dynamic mechanical response and failure behaviour of AlMgB14-based ceramic: experimental observation, constitutive modelling and ballistic performance evaluation

Journal of Materials Research and Technology
AlMgB14-based ceramics have emerged as promising materials for ballistic protection due to their ultra-hardness and low density. However, their dynamic mechanical behaviour and ballistic performance remain underexplored.

Stochastic ratcheting of two dimensional colloids : Directed current and dynamical transitions

, 2015
We present results of molecular dynamics simulations for two-dimensional repulsively interacting colloids driven by a one dimensional asymmetric and commensurate ratchet potential, switching on and off stochastically. This drives a time-averaged directed

Erosion of dust aggregates [PDF]

, 2013
Aims: The aim of this work is to gain a deeper insight into how much different aggregate types are affected by erosion. Especially, it is important to study the influence of the velocity of the impacting projectiles.

Multimodal Locomotion of Soft Robots

Advanced Intelligent Systems, EarlyView.
This review comprehensively surveys recent advances in multimodal locomotion within soft robotics. Typical locomotion modes are summarized and categorized. Furthermore, the underlying mechanisms enabling multimodal locomotion are discussed and classified into three primary categories: active control‐based, reconfiguration‐based, and environment ...

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

Advanced 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 ...

Quantum behavior of graphene transistors near the scaling limit

, 2012
The superior intrinsic properties of graphene have been a key research focus for the past few years. However, external components, such as metallic contacts, serve not only as essential probing elements, but also give rise to an effective electron cavity,

Inverse scaling trends for charge-trapping-induced degradation of FinFETs performance [PDF]

, 2014
In this paper, we investigate the impact of a single discrete charge trapped at the top oxide interface on the performance of scaled nMOS FinFET transistors.

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

Angewandte 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 ...

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, EarlyView.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Markovian embedding of non-Markovian superdiffusion

, 2010
We consider different Markovian embedding schemes of non-Markovian stochastic processes that are described by generalized Langevin equations (GLE) and obey thermal detailed balance under equilibrium conditions.
