We report a broadband metal-dielectric dispersive mirror (MDDM) based on Al/SiO/HfO thin films operating in the near-ultraviolet (UV) region. Demonstrating the combined benefits of both the wide reflective bandwidth of aluminum in the UV region and the flexible dispersion control capability of HfO/SiO multilayer films, the MDDM has a wide bandwidth, low total thickness, and precise dispersion compensation ability. We propose an initial design based on a shortwave reflection enhancement structure (SWRES) to prevent shortwave light from obtaining a second time-dispersion compensation in the deep metal layer.

The multi-layer compressive light field (CLF) three-dimensional (3D) display suffers from image artifacts due to layer misalignment. In this paper, we propose to reduce the image artifacts by improving the intensity distribution uniformity of the layer images. To achieve this, a global optimization algorithm based on gradient descent (GD) is proposed.

Structured illumination-based super-resolution Förster resonance energy transfer microscopy (SISR-FRETM) has facilitated better observation of molecular behavior in living cells. However, SIM tends to produce artifacts in reconstruction, especially when the raw SIM inputs are of low signal-to-noise ratio (SNR) or out-of-focus, leading to erroneous signals in subsequent FRET. Current SIM quality evaluation metrics fail to utilize both SNR and out-of-focus features, making it challenging to classify unqualified raw data for FRET.

A point cloud filtering method is presented for atmospheric layer detection from lidar data. The method involves rising edge event recognition based on a wavelet transform function. Density-based clustering was then utilized to separate the real boundary from the original noisy point clouds based on continuous distribution characteristics of cloud and aerosol layer.

Dual-comb ranging (DCR), with its superior overall performance compared to traditional ranging technologies, has recently attracted widespread interest in the research community. Nevertheless, the ranging distance or the material of the targets is limited by the detection sensitivity of optical asynchronous linear sampling. This limitation restricts the application of DCR in several highly significant scenarios.

Article Synopsis
  • Single-photon LIDAR technology struggles with 3D reconstruction due to high noise, low accuracy, and slow processing times, making traditional statistical methods insufficient.
  • While CNNs show some improvement over traditional approaches, they fail to effectively capture long-range and global data features necessary for accurate reconstruction.
  • To overcome these challenges, the paper presents a new model using vision transformers and generative adversarial networks, which enhances feature extraction and overall reconstruction quality, demonstrating significant improvements in noisy real-world scenarios.

  • Aquatic environments contain antibiotic-resistant bacteria, but the specific presence of polymyxin-resistant Yersinia enterocolitica, which causes yersiniosis, is not well-studied until now.
  • Researchers isolated polymyxin-resistant strains from natural water, showing resistance to multiple antibiotics and a high capability to cause disease in the model organism Galleria mellonella, leading to a 90% mortality rate within 48 hours.
  • Whole genome sequencing revealed 26 antibiotic resistance genes and a close genetic relationship to strains from humans and swine, indicating that polymyxin-resistant Y. enterocolitica could be a significant health threat to humans.

Purpose: Terminal nucleotidyltransferase 5A (TENT5A), recently predicted as a non-canonical poly(A) polymerase, is critically involved in several human disorders including retinitis pigmentosa, cancer and obesity. However, the exact biological role of TENT5A in hepatocellular carcinoma (HCC) has not been elucidated.

Methods: The transcription level of TENT5A and clinical correlation were analyzed using the LIRI-JP cohort, the TCGA-LIHC cohort, and clinical tissue samples of HCC patients in our laboratory.

Aim: Gestational Diabetes Mellitus (GDM) is among the most common complications during pregnancy, posing serious risks to both the patient's and offspring's health and well-being. Alterations in the maternal microbiome are closely associated with the pathogenesis of GDM, with Extracellular Vesicles (EVs) facilitating communication between microbiota and the host. However, little is known about the relationship between the microbial composition within EVs and the pathogenesis of GDM.

Background: Transarterial microembolization (TAME) is a minimally invasive treatment for chronic musculoskeletal disorders. Identifying angiogenesis and the supplying vessels of the target joint is important but challenging. Although magnetic resonance imaging (MRI) is commonly used to diagnose musculoskeletal diseases, it typically excludes vascular imaging.

Controversies regarding the benefits of statin treatment on clinical outcomes in coronary artery spasm (CAS) without obstructive coronary artery disease (CAD) persist due to limited data. In this retrospective nationwide population-based cohort study from the Taiwan National Health Insurance Research Database during the period 2000-2012, the matched cohorts consisted of 12,000 patients with CAS. After propensity score matching with 1:1 ratio, 2216 patients were eligible for outcome analysis in either statin or nonstatin group, with the mean follow-up duration of 4.

The tumour suppressor gene p53 is one of the most frequently mutated genes in lung cancer and these defects are associated with poor prognosis, albeit some debate exists in the lung cancer field. Despite extensive research, the exact mechanisms by which mutant p53 proteins promote the development and sustained expansion of cancer remain unclear. This review will discuss the cellular responses controlled by p53 that contribute to tumour suppression, p53 mutant lung cancer mouse models and characterisation of p53 mutant lung cancer.

Jaywalking, as a hazardous crossing behavior, leaves little time for drivers to anticipate and respond promptly, resulting in high crossing risks. The prevalence of Autonomous Vehicle (AV) technologies has offered new solutions for mitigating jaywalking risks. In this study, we propose a risk-aware deep reinforcement learning (DRL) approach for AVs to make decisions safely and efficiently in jaywalker-vehicle interactions.

Persistent pain frequently precipitates the development of anxiety disorders, yet the underlying mechanisms are not fully understood. In this study, we employed a mouse model that simulates trigeminal neuralgia and observed a marked reduction in the activity of GABAergic neurons in the lateral habenula (LHb), a critical region for modulating pain and anxiety. We utilized precise optogenetic and chemogenetic techniques to modulate these neurons, which significantly alleviated behaviors associated with pain and anxiety.

Article Synopsis
  • - The human constitutive androstane receptor (hCAR) is important for regulating how the body breaks down foreign substances, but a method for studying its binding with various compounds was needed.
  • - Researchers identified the compound SNS-032 and its derivative THAL-SNS-032 as candidates that bind to hCAR, leading to the development of a fluorescent probe called BODIPY FL SNS-032 that can effectively measure these interactions.
  • - BODIPY FL SNS-032 not only binds strongly to hCAR (with a binding affinity of around 300 nM) but also has significant binding affinities to various kinases, making it a useful tool for studying both hCAR and kinase function.
