The phonon inverse Faraday effect describes the emergence of a dc magnetization due to circularly polarized phonons. In this work we present a microscopic formalism for the phonon inverse Faraday effect. The formalism is based on time-dependent second order perturbation theory and electron phonon coupling.

Purpose: To investigate whether in diabetic cataract (DC), FoxO1 regulates high glucose (HG)-induced activation of NLRC4/IL-6 inflammatory mediators in human lens epithelial cells (SRA01/04) via the JAK1/STAT1 pathway, leading to cataract formation.
Methods: Expression levels of FoxO1, inflammatory factor IL-6 and inflammatory vesicle NLRC4 were examined in SRA01/04 under high glucose (HG) stress at 25-150 mM. Rat lenses were also cultured using HG medium with or without the addition of the FoxO1 inhibitor AS1842856 and the JAK1 agonist RO8191.

Background: Hepatitis B is a liver infection caused by HBV. Infected individuals who fail to control the viral infection develop chronic hepatitis B and are at risk of developing life-threatening liver diseases, such as cirrhosis or liver cancer. Dendritic cells (DCs) play important roles in the immune response against HBV but are functionally impaired in patients with chronic hepatitis B.

Women face unique and multifaceted challenges throughout their lifespans, shaped by biological, societal, and health care-related factors. These challenges have led to gender disparities in disease burden, access to care, and representation in medical research, underscoring the need to increase targeted investments in women's health. Historically, research on diseases that disproportionately affect women has been underfunded, hindering progress in closing gender health gaps.

Devices with a highly nonlinear resistance-voltage relationship are candidates for neuromorphic computing, which can be achieved by highly temperature dependent processes like ion migration. To explore the thermal properties of such devices, Scanning Thermal Microscopy (SThM) can be employed. However, due to the nonlinearity, the high resolution and quantitative method of AC-modulated SThM cannot readily be used.

Background: Geographic stent-ostium mismatch is an important predictor of target lesion failure after percutaneous coronary intervention of an aorto-ostial right coronary artery lesion. Optimal visualization of the aorto-ostial plane is crucial for precise stent implantation at the level of the ostium. This study investigates whether preprocedural 3-dimensional computed tomography (3DCT), with determination of the optimal viewing angle, would allow for more precise stent implantation and reduce procedure time, contrast, and radiation dose.

Background: This study aimed to compare the economic value of intermittent-scanning continuous glucose monitoring (isCGM) with self-monitoring of blood glucose (SMBG) in adults with type 1 diabetes (T1D).
Methods: Participants were placed on either an isCGM or SMBG arm for 84 days, in a randomized, crossover setup with a 28-day washout period. Clinically relevant hypoglycemia (<54 mg/dL) and severe hypoglycemia (SH) risks were calculated by analyzing the data from isCGM.

The methane seeps on the Pacific margin of Costa Rica support extensive animal diversity and offer insights into deep-sea biogeography. During five expeditions between 2009 and 2019, we conducted intensive faunal sampling via 63 submersible dives to 11 localities at depths of 300-3600 m. Based on these expeditions and published literature, we compiled voucher specimens, images, and 274 newly published DNA sequences to present a taxonomic inventory of macrofaunal and megafaunal diversity with a focus on invertebrates.

Retrospective datasets offer essential context for conservation by revealing species' ecological roles before industrial-era human impacts. We analysed isotopic compositions of pre-industrial and modern sea otters () to reconstruct pre-extirpation ecology and offer insights for management. Our study focuses on southeast Alaska (SEAK), where sea otters are recolonizing, and northern Oregon, where translocations are being considered.

The next step in the evolution of static 3-dimensionally (3D) printed models may be the creation of "smart" models, where subcomponents can be seamlessly interacted with through a feedback mechanism, with potential applications in trainee education and patient counseling. Considering the complexity of the ventricular and cisternal systems, they were chosen for segmentation, using Materialize InPrint with outward hollowing using 2.5-mm wall thickness.

Objective: This study evaluated the performance of a deep learning-based vertebral compression fracture (VCF) detection tool in patients with incidental VCF. The purpose of this study was to validate this tool across multiple sites and multiple vendors.
Methods: This was a retrospective, multicenter, multinational blinded study using anonymized chest and abdominal CT scans performed for indications other than VCF in patients ≥50 years old.
We present a wideband rectifying metasurface (RMS) with enhanced system efficiency for wireless power transmission and energy harvesting. The RMS consists of periodic arrays with integrated diodes, with a high input impedance matched with the diodes, thus eliminating the matching network between metasurface (MS) and rectifier. Besides, a unique harmonic feedback network is embedded in each unit cell, rectifying the high-order harmonic generated by the diode repeatedly, improving the total efficiency over a wide bandwidth.

One promising approach is the implementation of radio-over-fiber (RoF)-based distributed antenna systems (DAS), which can efficiently transmit radio frequency signals over optical fiber, especially in dense indoor environments. However, analog RoF systems face challenges, including noise, nonlinearities, and power fading caused by chromatic dispersion.

The RMS unit adopts a rotationally symmetric structure consisting of double rings and cross-shaped elements, with two diodes placed in the gap of the cross-shaped to achieve polarization insensitivity. Simultaneously, by adjusting the dimensions of the "double ring and cross" structure, its output impedance is varied to achieve conjugate matching with the diode input impedance, thereby eliminating the impedance matching network.
