Self‐Rhythmic Soft Pneumatic Pressure Regulation System Based on Self‐Excited Oscillation of Jet Hose

Advanced Intelligent Systems, EarlyView.
This study presents a soft pneumatic pressure regulation system that uses self‐excited hose oscillations to convert constant pressure (90–150 kPa) into rhythmic output. Simulations and experiments demonstrate tunable oscillation frequencies (5.9–11.1 Hz) through adjustments in pressure, hose length, and jet hole diameter.

Dynamic Single‐Input Control of Multistate Multitransition Soft Robotic Actuator

Advanced Intelligent Systems, EarlyView.
A concept for reducing the number of control inputs to one in a system with N degrees of freedom, is presented. Incorporating structural instabilities, cleverly, enables choosing any desired trajectory out of (N!)2 with only one input. The concept is demonstrated experimentally, along with analytical insights and numerical simulations.

Functional models from limited data: A parametric and multimodal approach to anatomy and 3D kinematics of feeding in basking sharks (Cetorhinus maximus)

The Anatomical Record, EarlyView.
Abstract Basking sharks, Cetorhinus maximus (Gunnerus, Brugden [Squalus maximus], Det Kongelige Norske Videnskabers Selskabs Skrifter, 1765, vol. 3, pp. 33–49), feed by gaping their mouths and gill slits, greatly reorienting their cranial skeletons to filter food from water.

Virtual Estimator for Piecewise Linear Systems Based on Observability Analysis

Sensors, 2013
This article proposes a virtual sensor for piecewise linear systems based on observability analysis that is in function of a commutation law related with the system’s outpu. This virtual sensor is also known as a state estimator.

Time‐Dependent Effect of Prophylactic Trimethoprim‐Sulfamethoxazole on the Incidence of Serious Infections in Antineutrophil Cytoplasmic Antibody–Associated Vasculitis: A Target Trial Emulation Study

Arthritis &Rheumatology, EarlyView.
Objective The objective of this study was to investigate the effect of prophylactic trimethoprim‐sulfamethoxazole (TMP‐SMX) on the incidence of serious infections in patients with antineutrophil cytoplasmic antibody–associated vasculitis (AAV). Methods This multicenter cohort study was designed to emulate a target trial that studied 296 patients with ...

On the Age Distribution of Classical Cepheids in the Galaxy

Astronomische Nachrichten, EarlyView.
ABSTRACT We revisit the problem of the positive correlation between age and Galactocentric distance seen in Galactic Classical Cepheids, which at first sight may seem counter‐intuitive in the context of inside‐out galaxy formation. To explain it, we use the Besançon Galaxy Model and a simulation of star particles in the Galactic disc coupled with ...

Using infeasible path cuts to solve Electric Vehicle Routing Problems with realistic charging functions exactly within a branch-and-cut framework

EURO Journal on Transportation and Logistics
The paper investigates the Electric Vehicle Routing Problem with a non-linear concave and strictly monotonic increasing charging function. In the literature, the non-linear charging function is typically approximated by a piecewise linear charging ...

A Comprehensive Model for Separating Systematic Bias and Noise in Metabolomic Timecourse Data—A Nonlinear B‐Spline Mixed‐Effects Approach

Biotechnology and Bioengineering, EarlyView.
A nonlinear B‐spline mixed effects model for the simultaneous detection and correction of systematic error in timecourse metabolomics data. Systematic errors–such as those from dilution or incomplete extraction–affect all metabolites similarly and can be corrected by fitting all metabolites together in a single model.
