Single‐Shot Auto‐Exposure and High Dynamic Range Imaging Based on Asynchronous Operation of Pixel Array Circuitry

International Journal of Circuit Theory and Applications, EarlyView.
Method for automated asynchronous adaptation to high dynamic range lighting conditions during image acquisition. ABSTRACT This paper introduces an image formation technique that realizes automatic adaptation to the illumination conditions during image capture.

Resonance‐induced restoration of rock permeability degraded by heavy components of crude oil

Deep Underground Science and Engineering, EarlyView.
Resonance‐induced changes occur in filtration properties of sedimentary rocks in crude paraffin oil flow under acoustic vibrations. Experimental data on (a) pressure drop; (b) permeability; (c) pressure at the rock inlet; and (d) pressure at the rock outlet are presented.

Dielectrophoresis Tutorial: Inspired by Hatfield's 1924 Patent and Boltzmann's Theory and Experiments of 1874

ELECTROPHORESIS, EarlyView.
ABSTRACT The first patent to describe dielectrophoresis (DEP) as a means and process to separate particles from a mixture was granted by the US Patent Office to Henry Stafford Hatfield in 1924. The novel methods of sample preparation and designs of electrode geometry covered by the patent's disclosures and claims describe the basis for most present‐day

eCherry: A Modelica Library for Modular Dynamic Modelling of Electrochemical Reactors

Electrochemical Science Advances, EarlyView.
ABSTRACT Electrochemical reactors offer promising pathways for defossilizing the chemical industry. To understand the operation as well as to evaluate and optimise their performance and efficiency, modelling presents a crucial tool. Currently, no comprehensive open‐source library for dynamic modelling of electrochemical reactors exists, and instead ...

Design and Optimization of a Robust Wide‐Area Damping Controller for Mitigating Inter‐Area Oscillations in Wind‐Integrated Power Systems

Energy Science &Engineering, EarlyView.
ABSTRACT In power networks, low‐frequency oscillations—particularly inter‐area oscillations—pose a serious threat to system stability because of disruptions like short‐circuit faults and the increasing use of renewable energy sources like wind farms. To lessen the negative impacts of time delays when sending distant signals, this study presents a novel

CO2 Storage Site Selection: A Comprehensive Review of Current Approaches

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Global warming, driven by increasing anthropogenic greenhouse gas emissions, has emerged as a critical environmental concern. Carbon capture and storage (CCS) technology offers a promising solution for reducing CO2 emissions, but its effectiveness depends on identifying suitable candidates that can ensure safe, long‐term storage of CO2.

Comparison of two infiltration equations with three‐terms expansions consistent with the approach of Philip theory

Irrigation and Drainage, EarlyView.
Abstract In this study, the approximate three‐term (3 T) one‐dimensional (1D) vertical infiltration equation by Valiantzas (3 T‐V) and the 3 T approximate infiltration equation of the quasi‐exact implicit (QEI) Haverkamp equation (3T‐R) by Rahmati et al. for both direct and inverse modelling of water infiltration into soils were evaluated.

On totally umbilical and minimal surfaces of the Lorentzian Heisenberg groups

Mathematische Nachrichten, EarlyView.
Abstract This paper has manifold purposes. We first introduce a description of the Gauss map for submanifolds (both spacelike and timelike) of a Lorentzian ambient space and relate the conformality of the Gauss map of a surface to total umbilicity and minimality.

The 2‐divisibility of divisors on K3 surfaces in characteristic 2

Mathematische Nachrichten, EarlyView.
Abstract We show that K3 surfaces in characteristic 2 can admit sets of n$n$ disjoint smooth rational curves whose sum is divisible by 2 in the Picard group, for each n=8,12,16,20$n=8,12,16,20$. More precisely, all values occur on supersingular K3 surfaces, with exceptions only at Artin invariants 1 and 10, while on K3 surfaces of finite height, only n=

Stability and Hopf Bifurcations Analysis in a Three‐Phase Dengue Diffusion Model With Time Delay in Fractional Derivative and Laplace–Adomian Decomposition Numerical Approach

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This study examines the complex dynamics of dengue transmission by incorporating time delay into a comprehensive model. The model is designed to capture several essential components, including steady‐state events, immune waning, recuperation from infection, and partial shielding in human populations.
