FABP4 as a Mediator of Lipid Metabolism and Pregnant Uterine Dysfunction in Obesity
Advanced Science, EarlyView.Obesity during late pregnancy contributes to uterine smooth muscle dysfunction, but the underlying mechanisms are unclear. This study identifies fatty acid binding protein 4 (FABP4) as a key player in the process, mediating excessive fatty acid uptake, lipid accumulation, and mitochondrial dysfunction in myometrial cells. FABP4 could be a novel uterine

Tailored 3D Lattice Microstructures for Enhanced Functionality in Blood‐Gas Exchange
Advanced Science, EarlyView.Common hollow fiber structures are associated with inhomogeneous flow, leading to many complications in the medical application of extracorporeal membrane oxygenation. Using locally adapted lattice structures, the overall flow distribution can be manipulated.

Arithmetic and pseudo-arithmetic billiards
, 2015 The arithmetic triangular billiards are classically chaotic but have Poissonian energy level statistics, in ostensible violation of the BGS conjecture. We show that the length spectra of their periodic orbits divides into subspectra differing by the parity of the number of reflections from the triangle sides; in the quantum treatment that parity ...

Mathematische Nachrichten, 2014 An integer $n$ is said to be \textit{arithmetic} if the arithmetic mean of its divisors is an integer. In this paper, using properties of the factorization of values of cyclotomic polynomials, we characterize arithmetic numbers. As an application, in Section 2, we give an interesting characterization of Mersenne numbers.

Modulating Dynamic Photoresponse Behavior of Organic Phototransistors Through Morphology Control
Advanced Electronic Materials, EarlyView.An effective and facile strategy is investigated to regulate the photoresponse behavior from photomemory to photoswitching through controlling the crystalline and transporting properties of photosensitive layer. Highly ordered, high‐mobility films typically shows photomemory behavior whereas films with poor crystallinity and low charge mobility tend to

Primitive geodesic lengths and (almost) arithmetic progressions [PDF]
Publ. Mat. 63 (2019), 183--218, 2014 In this article, we investigate when the set of primitive geodesic lengths on a Riemannian manifold have arbitrarily long arithmetic progressions. We prove that in the space of negatively curved metrics, a metric having such arithmetic progressions is quite rare.

Encapsulated Organohydrogel Couplants for Wearable Ultrasounds
Advanced Electronic Materials, EarlyView.Hydrogels are ideal for wearable ultrasonic devices but suffer from water loss during long‐term monitoring. Adding excessive glycerol increases attenuation, while elastomer encapsulation causes uneven interfaces due to shrinkage and scattering acoustic waves.
