Integrative multi-omics and big data analysis of global nutrition and radiotherapy trends.

Background: Radiotherapy serves as a crucial modality in cancer treatment, frequently synergizing with other therapies to enhance patient outcomes. Unfortunately, radiotherapy is often accompanied by nutritional impairments, including dysphagia and malnutrition, which hinder patient recovery and treatment efficacy. Moreover, nutritional abnormalities accompanied by metabolic reprogramming may lead to alterations across multiple omics domains.

Patients with Extensive-Stage Small Cell Lung Cancer Harboring Less Than 4 Metastatic Sites May Benefit from Immune Checkpoint Inhibitor Rechallenge by Reshaping Tumor Microenvironment.

Background: Immune checkpoint inhibitors (ICIs) has prolonged survival in patients with extensive-stage small cell lung cancer (ES-SCLC) as first-line treatment. However, whether ICI rechallenge could bring survival benefit to patients with ES-SCLC following its failure as first-line treatment remains unknown. Therefore, we aim to address the issue and identify the cohort of patients that may derive such benefit.

Instability, changes, and internal structure of children's attitudes toward mathematics in primary school: A four-wave investigation.

The longitudinal person-oriented study aimed to explore profiles, stability, gender differences, and compositional relations of math attitudes by tracking Chinese third graders (N = 1013, M = 8.92 ± 0.46, N = 404) in four waves with 1-year intervals.

Math attitudes and math anxiety predict students' perception of teacher support in primary school, but not vice versa.

Background: Both teacher support and math attitudes have been identified as associated with math anxiety in primary school children. However, little is known about how they are interrelated longitudinally.

Aims: The study was designed to examine the associations among perceived teacher support, math attitudes, and math anxiety in Chinese primary school students.

The Consistence of Dynamic Contrast-Enhanced MRI and Filter-Exchange Imaging in Measuring Water Exchange Across the Blood-Brain Barrier in High-Grade Glioma.

Background: Water exchange across blood-brain barrier (BBB) (WEX ) is an emerging biomarker of BBB dysfunction with potential applications in many brain diseases. Several MRI methods have been proposed to measure WEX , but evidence remains scarce whether different methods can produce comparable WEX .

Purpose: To explore whether dynamic contrast-enhanced (DCE)-MRI and vascular water exchange imaging (VEXI) could produce comparable WEX in high-grade glioma (HGG) patients.

3D Simulations of Freezing Characteristics of Double-Droplet Impact on Cold Surfaces with Different Wettability.

In this work, the freezing characteristics of double-droplet impact on three typical wettability surfaces were investigated by coupling the solidification and melting VOF models. Different temperature conditions were adopted to study the influence of icing speed on droplet behavior. Simulation results show that the motion of the double-droplet impact is consistent with that of a single droplet in the early spreading stage but behaves differently in the retraction stage.

Research on a tunable monochromatic X-rays source in (5∼40) keV.

The monochromatic X-rays produced by Bragg diffraction has the advantage of continuously adjustable energy, which is the preferred scheme to realize the monochromatic X-rays. In order to establish a (5-40) keV monochromatic X-rays facility, the Bragg diffraction of crystal monochromator is studied. The position of the emitted X-rays beam is required to remain unchanged when the Bragg angle is adjusted to accurately calibrate the detection efficiency.

Physical Simulation Model of WO Electrochromic Films Based on Continuous Electron-Transfer Kinetics and Experimental Verification.

Tungsten oxide (WO) electrochromic devices have attracted a lot of interest in the energy conservation field and have shown a preliminary application potential in the market. However, it is difficult to quantitatively direct experiments with the existing electrochromic theoretical models, which can restrict the further development of electrochromism. Here, an electrochromic physical simulation model of WO films was built to solve the above problem.

Effect of the Ammonium Tungsten Precursor Solution with the Modification of Glycerol on Wide Band Gap WO Thin Film and Its Electrochromic Properties.

Tungsten trioxide (WO) is a wide band gap semiconductor material, which is commonly not only used, but also investigated as a significant electrochromic layer in electrochromic devices. WO films have been prepared by inorganic and sol-gel free ammonium tungstate ((NH)WO), with the modification of glycerol using the spin coating technique. The surface tension, the contact angle and the dynamic viscosity of the precursor solutions demonstrated that the sample solution with a 25% volume fraction of glycerol was optimal, which was equipped to facilitate the growth of WO films.
