Published: December 2023

Abstract
The offshore crude oil spill has caused serious environmental damage and affected the balance of the ecosystem. Due to the high viscosity and poor fluidity of crude oil, conventional adsorbents cannot effectively remove it. The heat converted from solar energy can reduce the viscosity of the crude oil, improved its fluidity, allowing it to be adsorbed by a porous material and then recycle, it is considered an effective approach. Herein, we have designed a melamine composite sponge decorated with Fe3O4 and modified by PDMS (MS@Fe3O4-PDMS) with good photothermal conversion performance, which can recover viscous crude oil with the assistance of solar energy. The surface temperature of MS@Fe3O4-PDMS can reach around 88.0 ℃ under the light intensity of 1 kW m− 2, effectively heating crude oil and accelerating its absorption. In the continuous crude oil recovery experiment, the absorption rate of MS@Fe3O4-PDMS reached 52.46 kg·m− 2·h− 1. In addition, the composite sponge has good processability, facile preparation method, and practical application potential.

Abstract
In 1998, the Hefei National Synchrotron Radiation Laboratory completed the 6T superconducting Wiggler magnets system. The consumption of liquid helium increases year by year during long operations. In order to upgrade the cryogenic system and realize zero volatilization of liquid helium, the GM cryocoolers are introduced as the cooling source. The liquid nitrogen and radiation-proof cold screen of the original cryogenic system were cancelled, and the original copper current lead was upgraded and replaced with the high-temperature superconducting current lead component. The cryogenic system's required cooling capacity is 2.33 W at 4.2 K and 108 W at 60 K. The system then selects three GM cryocoolers as the cryogenic source, which can provide 3.75 W at 4.2 K and 210 W at 60 K. In the absence of an external precooling source, the final cryogenic system successfully cooled and produced liquid helium at a liquefaction rate of 12 L/day at 1.1 bar (inflationary pressure) and had an excess cooling capacity of more than 1.05 W at 4.1 K.

Abstract

In this paper, we study skew constacyclic codes over a class of non-chain rings $\mathcal{T}=\mathbb{F}_q[u_1,u_2,\ldots, u_r]/ \langle f_i(u_i), u_iu_j-u_ju_i\rangle_{i,j=1}^r$, where $q=p^m$, $p$ is some odd prime, $m$ is a positive integer and $f_i(u_i)$ are non-constant polynomials which split into distinct linear factors. We discuss the structural properties of skew constacyclic codes over $\mathcal{T}$ and their dual. We characterize (Euclidean and Hermitian) dual-containing skew constacyclic codes. These characterizations serve as a foundational framework for the development of techniques to construct quantum codes. Consequently, we derive plenty of new quantum codes including many Maximum Distance Separable (MDS) quantum codes, and many quantum codes with better parameters than existing ones. Our work further extends to the characterization of skew constacyclic Euclidean and Hermitian Linear Complementary Dual (LCD) codes over $\mathcal{T}$, and we establish that their Gray images also preserve the LCD property. From this analysis, we derive numerous Maximum Distance Separable (MDS) codes and Best-Known Linear Codes (BKLC) over $\mathbb{F}_q$.

Published: December 2023

Abstract
Objective
This study aims to assess a machine learning (ML) algorithm using multimodal imaging to accurately identify risk factors for uveal melanoma (UM) and aid in the diagnosis of melanocytic choroidal tumors.
Subjects and Methods
This study included 223 eyes from 221 patients with melanocytic choroidal lesions seen at the eye clinic of the University of Illinois at Chicago between 01/2010 and 07/2022. An ML algorithm was developed and trained on ultra-widefield fundus imaging and B-scan ultrasonography to detect risk factors of malignant transformation of choroidal lesions into UM. The risk factors were verified using all multimodal imaging available from the time of diagnosis. We also explore classification of lesions into UM and choroidal nevi using the ML algorithm.
Results
The ML algorithm assessed features of ultra-widefield fundus imaging and B-scan ultrasonography to determine the presence of the following risk factors for malignant transformation: lesion thickness, subretinal fluid, orange pigment, proximity to optic nerve, ultrasound hollowness, and drusen. The algorithm also provided classification of lesions into UM and choroidal nevi. A total of 115 patients with choroidal nevi and 108 patients with UM were included. The mean lesion thickness for choroidal nevi was 1.6 mm and for UM was 5.9 mm. Eleven ML models were implemented and achieved high accuracy, with an area under the curve of 0.982 for thickness prediction and 0.964 for subretinal fluid prediction. Sensitivity/specificity values ranged from 0.900/0.818 to 1.000/0.727 for different features. The ML algorithm demonstrated high accuracy in identifying risk factors and differentiating lesions based on the analyzed imaging data.
Conclusions
This study provides proof of concept that ML can accurately identify risk factors for malignant transformation in melanocytic choroidal tumors based on a single ultra-widefield fundus image or B-scan ultrasound at the time of initial presentation. By leveraging the efficiency and availability of ML, this study has the potential to provide a non-invasive tool that helps to prevent unnecessary treatment, improve our ability to predict malignant transformation, reduce the risk of metastasis, and potentially save patient lives.

Abstract

The microgravity environment aboard the International Space Station (ISS) provides a unique stressor that can help understand underlying cellular and molecular drivers of pathological changes observed in astronauts with the ultimate goals of developing strategies to enable long-term spaceflight and better treatment of diseases on Earth. We used this unique environment to evaluate the effects of microgravity on kidney proximal tubule epithelial cell (PTEC) response to serum exposure and vitamin D biotransformation capacity. To test if microgravity alters the pathologic response of the proximal tubule to serum exposure, we treated PTECs cultured in a microphysiological system (PT-MPS) with human serum and measured biomarkers of toxicity and inflammation (KIM-1 and IL-6) and conducted global transcriptomics via RNAseq on cells undergoing flight (microgravity) and respective controls (ground). We also treated 3D cultured PTECs with 25(OH)D3 (vitamin D) and monitored vitamin D metabolite formation, conducted global transcriptomics via RNAseq, and evaluated transcript expression of CYP27B1, CYP24A1, or CYP3A5 in PTECs undergoing flight (microgravity) and respective ground controls. We demonstrated that microgravity neither altered PTEC metabolism of vitamin D nor did it induce a unique response of PTECs to human serum, suggesting that these fundamental biochemical pathways in the kidney proximal tubule are not significantly altered by short-term exposure to microgravity. Given the prospect of extended spaceflight, more study is needed to determine if these responses are consistent with extended (> 6 month) exposure to microgravity.

Abstract

Increasing active sites in catalysts is of utmost importance for catalytic processes, frequently fascinating global scientists. In recent years, using graphitic carbon nitrides (g-C3N4) for the piezo-photocatalytic generation of fine chemicals, such as hydrogen peroxide (H2O2) from oxygen (O2) and water (H2O), is of current interest due to its flexibility in molecular structures to boost catalytic properties. However, due to its intrinsic nature, bulk g-C3N4 suffers from low catalytic outcomes. To enhance catalytic performances, we, in this research, engineered g-C3N4 by atomically dispersing aluminum (Al) or indium (In) sites to provide catalytic active centers via one-step thermal shock polymerization. The empirical analyses show that In atoms would occupy the near positions of carbon vacancies (VC) to form N-VC@In-O bonds. This replacement would produce the highest formation energy based on the theoretical calculations, improving the stability of atom-dispersive materials. In addition, under catalytic conditions, the formation of oxygenic radicals would strongly be associated with the enhanced formation of H2O2. Unhappily, hydroxyl radicals would induce catalytic deactivation due to the attacks of these highly oxidative radicals on the active centers, thus changing the catalysts' structures and reducing the catalytic outcomes.
Vitamin D deficiency and its association with Depression in under 18s: A mysterious relationship of sunlight with darkness
Authors: Khan Hayat 
Published: December 2023

Abstract
Vitamin D receptors are present in areas of the brain involved in mood regulation, such as the hippocampus and prefrontal cortex. It is suggested that Vitamin D may modulate the synthesis and release of neurotransmitters, including serotonin, dopamine, and norepinephrine, which play crucial roles in mood regulation and are implicated in depression. Vitamin D also has anti-inflammatory properties and can influence immune system functioning. Chronic inflammation has been linked to the development of depression. Vitamin D may help regulate the immune response, reducing inflammation and potentially mitigating depressive symptoms. The deficiency of this vitamin has been previously thought to be not as common as recognized now. This review looked at several studies to explore the association of Vitamin D deficiency and clinical depression in children and adolescents. Many studies based on adult population have found plausible link between Vitamin D deficiency and depression but the research in under 18s have been limited. Based on the available research, mental health clinicians need to maintain a high clinical suspicion, to make early diagnosis and treatment of vitamin D deficiency.
