A Novel Crawling Robot Based on the Hexagonal Mesh Structure and Enhanced PID Control Strategy

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT The locomotion of crawling robots is similar to that of caterpillars, relying on foot adhesion and body contraction to ensure flexible movement without compromising stability. However, most existing pneumatic soft crawling robots are incapable of simultaneously achieving forward, backward, turning, and climbing capabilities.

Shaping expectations, losing flexibility: A study of CEO promises as strategic communication tools

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary CEO promises are powerful but understudied communication tools. We develop a dual‐mechanism framework theorizing that while CEO promises elevate stakeholder expectations, they simultaneously constrain strategic flexibility. We argue that CEO promise‐making is shaped by two competing pressures: making more promises when the ...

Modeling small‐angle scattering data of porous and/or bicontinuous structures in n dimensions

open access: yesJournal of Applied Crystallography, EarlyView.
A small‐angle scattering fitting function is derived for porous materials with arbitrary fractal dimension. It includes a correlation peak and a power law at higher q.Fractal structures are often observed in small‐angle scattering experiments where a simple power law q−α describes the scattering intensity over many orders of magnitude.

On the optimization of the geometric pattern for structured illumination based X‐ray phase contrast and dark‐field imaging: a simulation study and its experimental validation

open access: yesJournal of Synchrotron Radiation, EarlyView.
Single‐mask phase contrast and dark‐field imaging methods offer the great advantage of being simple to implement, translating most of the complexity to the numerical side. In this work, we study the impact of the modulation topology on the image quality retrieved both on numerical simulation and experiments.Phase contrast and dark‐field imaging are ...

How Tether Depegging Affects Cryptocurrency Returns

open access: yesAccounting &Finance, EarlyView.
ABSTRACT This paper examines the relationship between Tether depegging events and the returns of ten major cryptocurrencies from November 2017 to November 2024. We distinguish between upward and downward deviations from the Tether peg, identifying these events as threshold exceedances based on historical prices, using both constant parameter and ...

Genetic risk factors in Finnish patients with Fuchs endothelial corneal dystrophy

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose To study the genetic risk factors of Fuchs endothelial corneal dystrophy (FECD) in the Finnish population using hospital‐based and large biobank cohorts. Methods We genotyped a cohort of 107 Finnish patients with FECD for the primary associated genetic risk factor, the TCF4 (CTG)>50 expansion, and studied their clinical phenotype.
