A novel method for the rapid separation and determination of five polar 5‐nitroimidazoles in water from different sources by pressurized capillary electrochromatography has been developed. Compared with the gradient elution mode and the packed nonpolar columns which were usually utilized for the separation of 5‐nitroimidazoles, a simple isocratic ...

Abstract Sedentary behavior (SB) poses significant health risks. Still, older adults frequently engage in SB, presumably driven by habit. As stable contexts and rewarding experiences reinforce habits, understanding these mechanisms is essential for designing effective interventions. This study used sensor‐triggered ecological momentary assessments (EMA)

Abstract A number of dielectric materials have been employed for on‐chip frequency comb generation. Silicon based dielectrics such as silicon dioxide (SiO2) and silicon nitride (SiN) are particularly attractive comb materials due to their low optical loss and maturity in nanofabrication.

Organic and Metallacages for Chemical Sensing: Progress in Water‐Compatible Systems
Supramolecular cages function as three‐dimensional receptors for selective molecular recognition and sensing, and this review outlines design principles for water‐stable architectures, key analyte‐ and medium‐dependent challenges, recent water‐compatible examples (including polymer‐integrated systems), and future opportunities for cage‐based ...

Kinematics and Dynamics of a Tensegrity‐Based Water Wave Energy Harvester
A tensegrity‐based water wave energy harvester is proposed. The direct and inverse kinematic problems are investigated by using a geometric method. Afterwards, the singularities and workspaces are discussed. Then, the Lagrangian method was used to develop the dynamic model considering the interaction between the harvester and water waves.

Abstract Kirberg et al. described in 2016 a one‐step gastrostomy tube placement, the ‘pull‐introducer’ technique, designed for small‐for‐gestational‐age neonates, combining two endoscopic techniques. Nine infants (weight 3.4–8.1 kg) in our centre required a gastrostomy placement (two infants) or a combined gastrostomy placement and Nissen ...

Enhancing Weak‐Signal Carrier Phase Tracking in GNSS Receivers
Examining the performance of the GNSS PLL, this paper presents novel results describing the statistical properties of four popular phase estimators under both strong‐ and weak‐signal conditions when subject to thermal noise, deterministic dynamics, and typical pedestrian motion.

Encouraging politicians to act on climate: A field experiment with local officials in six countries
Abstract Local governments play an important role in addressing the climate crisis. However, despite public support for climate action, local policy responses have been limited. We argue that (1) biased beliefs about voter preferences, (2) the time horizon for credit claiming, and (3) source credibility are barriers for legislators to learn and adopt ...
