Authentication using pulse-response biometrics [PDF]

Communications of the ACM, 2017
We propose a new biometric based on the human body's response to an electric square pulse signal, called pulse-response. We explore how this biometric can be used to enhance security in the context of two example applications: (1) an additional authentication mechanism in PIN entry systems, and (2) a means of ...

Analysis of security protocols using finite-state machines [PDF]

, 2015
This paper demonstrates a comprehensive analysis method using formal methods such as finite-state machine. First, we describe the modified version of our new protocol and briefly explain the encrypt-then-authenticate mechanism, which is regarded as more ...

Ion‐Gating Reservoir Computing for Preprocessing‐Free Speech Recognition from Throat Vibrations

Advanced Electronic Materials, EarlyView.
This work presents a throat‐mounted mechanoelectric sensor integrated with an ion‐gel/graphene reservoir device for on‐device speech recognition. The system converts raw biomechanical vibrations into rich nonlinear current dynamics, enabling efficient classification through a simple linear readout. The approach highlights a compact and tunable physical‐

An ultra‐processed food‐based cafeteria diet induces obesity, metabolic dysfunction, and tissue‐specific gene dysregulation in C57BL/6 mice

Animal Models and Experimental Medicine, EarlyView.
This schematic figure illustrates the experimental design and key findings of the study. Forty male C57BL/6 mice were assigned to either a standard diet control group or a cafeteria diet (CAFD) group for 16 weeks. CAFD induces obesity, insulin resistance (HOMA‐IR), hepatic steatosis, and dysregulation of a number of genes in visceral and subcutaneous ...

Synergistic Microstructure and Dielectric Engineering of Recyclable Single‐Electrode Triboelectric Nanogenerators for Sustainable Smart Homes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A recyclable triboelectric nanogenerator integrating a pseudo‐honeycomb microstructure with liquid metal doping achieves 120% higher output (122 mW m−2) and >90% retention over seven cycles, enabling self‐powered smart home functions. The performance of single‐electrode triboelectric nanogenerators (SE‐TENGs) is governed by the effective contact area ...
