The application of single-medium fluids is relatively ineffective due to their limited functionality in heavy oil reservoirs. To compensate for the limitations of single-medium fluid injection, multimedium collaborative technologies have been proposed and have become a primary focus of research. In this paper, a series of experiments were designed and conducted on multimedium-assisted steam flooding in horizontal wells based on the heavy oil samples from the W block in Xinjiang Oil fields, China.

Introdcution: Parkinson's Disease (PD) is a progressive neurodegenerative disorder that primarily impacts motor function and is prevalent among older adults worldwide. Gait performance (such as speed, stride, step, and so on) has been shown to play a significant role in diagnosis, treatment, and rehabilitation. Fortunately, advancements in computer science have provided serial ways to calculate gait-related parameters, offering a more accurate alternative to the complex and often imprecise assessments traditionally relied upon by trained professionals.

Introduction: Digital technologies have significantly advanced the detection of emotional disorders (EmD) in clinical settings. However, their adoption for long-term monitoring remains limited due to reliance on fixed testing formats and active user participation. This study introduces a novel approach utilizing common ball game videos-table tennis-to implicitly capture eye movement trajectories and identify EmD through natural viewing behavior.

Precursor-derived silicon carbide (SiC) ceramics have been widely used as absorbing materials, but the residual carbon sink produced by ceramicization limits their application under high-temperature and oxygen-containing conditions, such as the nozzle or jet vane of high-speed aircraft. In this paper, a novel molybdenum carbide/silicon carbide (MoC/SiC) microwave-absorbing ceramic with a two-dimensional sheet structure was obtained through the pyrolysis of polycarbosilane-coated molybdenum sulfide (PCS@MoS). The results indicate that addition of an appropriate amount of MoS can react with the free carbon generated during the pyrolysis of PCS, thereby reducing the material's carbon content and forming MoC.

Human epidermal growth factor receptor 2 (HER2) is an anti-cancer drug target for colon cancer. Among patients with colorectal malignancy (colorectal cancer, CRC), those with HER2 mutations have a poor overall prognosis and a significantly increased drug resistance. In recent years, anti-HER2 therapeutic drugs have developed rapidly.

This paper presents an automated method for solving the initial structure of compact, high-zoom-ratio mid-wave infrared (MWIR) zoom lenses. Using differential analysis, the focal length variation process of zoom lenses under paraxial conditions is investigated, and a model for the focal power distribution and relative motion of three movable lens groups is established. The particle swarm optimization (PSO) algorithm is introduced into the zooming process analysis, and a program is developed in MATLAB to solve for the initial structure.

The aim of dynamic prediction is to provide individualized risk predictions over time, which are updated as new data become available. In pursuit of constructing a dynamic prediction model for a progressive eye disorder, age-related macular degeneration (AMD), we propose a time-dependent Cox survival neural network (tdCoxSNN) to predict its progression using longitudinal fundus images. tdCoxSNN builds upon the time-dependent Cox model by utilizing a neural network to capture the nonlinear effect of time-dependent covariates on the survival outcome.

Polymer gels have been widely used in flexible electronics, soft machines and impact protection materials. Conventional gels usually suffer from the inherent conflict between stiffness and toughness, severely hampering their applications. This work proposes a facile yet versatile strategy to break through this trade-off via the synergistic effect of crystal-domain cross-linking and chelation cross-linking, without the need for specific structure design or adding other reinforcements.

Optical zoom systems have found widespread applications in fields such as security and mobile phone lenses. The theory of zoom lens design has also developed from the first order to the third order. To address the demands for large aperture, wide field, and aspheric surfaces, a zoom system design method based on high-order structural aberration coefficients is introduced.

As optical systems continue to advance, non-uniform rational B-spline (NURBS) surfaces increasingly being considered in asymmetric optical systems due to their localized control characteristics. However, the representation of NURBS surfaces has complicated the analysis of these systems, leading to a significant computational burden. To address this challenge, we propose an optimizing algorithm for imaging optical systems based on high-precision ray tracing of NURBS surfaces.

Introduction: Oculomotor and gait dysfunctions are closely associated with cognition. However, oculo-gait patterns and their correlation with cognition in cerebral small vessel disease (CSVD) remain unclear.

Methods: Patients with CSVD from a hospital-based cohort (n = 194) and individuals with presumed early CSVD from a community-based cohort (n = 319) were included.

Article Synopsis
  • Esophageal cancer (EC) is a serious health issue, and cancer-associated fibroblasts (CAFs) are potential targets for new therapies, particularly regarding how they interact with the tumor microenvironment.
  • The study identified and characterized MMP14 CAFs and their role in promoting cancer cell migration and reducing the effectiveness of CD8 T cells, which are crucial for tumor killing, especially in the context of PD-1 immunotherapy.
  • Exosomal tsRNA from MMP14 CAFs was found to inhibit CD8 T cell activity, specifically with tsRNA-10522, suggesting that these CAFs could serve as markers for predicting responses to PD-1 immunotherapy in esophageal cancer.

Article Synopsis
  • A novel combination of neoadjuvant immunotherapy and chemotherapy (neoICT) has shown promise in improving outcomes for esophageal squamous-cell carcinoma (ESCC) patients, but issues like low response rates and therapy resistance remain.
  • *Using advanced techniques like single-cell RNA sequencing and multiplexed immunofluorescence, the study examined the tumor microenvironment (TME) to understand why some patients respond better to treatment than others.
  • *The research highlighted specific cancer-associated fibroblast (CAF) populations, particularly IL6+ CCL2+ and CD248+ CAFs, that contribute to therapy resistance by blocking T cell infiltration and inducing unfavorable immune responses, suggesting new targets for improving treatment effectiveness.

Introduction: Esophageal cancer is increasingly recognized as a significant global malignancy. The main pathological subtype of this cancer is esophageal squamous cell carcinoma (ESCC), which displays a higher degree of malignancy and a poorer prognosis. Reactive oxygen species (ROS) play a critical role in modulating the immune response to tumors, and understanding the regulation of ROS in ESCC could lead to novel and improved therapeutic strategies for ESCC patients.

Background: The efficacy of neoadjuvant chemo-immunotherapy (NAT) in esophageal squamous cell carcinoma (ESCC) is challenged by the intricate interplay within the tumor microenvironment (TME). Unveiling the immune landscape of ESCC in the context of NAT could shed light on heterogeneity and optimize therapeutic strategies for patients.

Methods: We analyzed single cells from 22 baseline and 24 post-NAT treatment samples of stage II/III ESCC patients to explore the association between the immune landscape and pathological response to neoadjuvant anti-PD-1 combination therapy, including pathological complete response (pCR), major pathological response (MPR), and incomplete pathological response (IPR).
