  • Per1 gene polymorphisms influence the relationship between brain white matter microstructure and depression risk Mon, 28 Nov 2022 06:00:00 -0500
    CONCLUSION: Our findings suggested that the PER1 genotypes and emotion-related WM microstructure may provide more effective measures of depression risk at an early phase.
  • Predictive machine learning model for microvascular invasion identification in hepatocellular carcinoma based on the LI-RADS system Mon, 28 Nov 2022 06:00:00 -0500
    CONCLUSION: A combination of LI-RADS features and non-LI-RADS features and serum alpha-fetoprotein value could be applied as a preoperative biomarker for predicting MVI by the machine learning approach. Furthermore, its good performance in the subgroup by LI-RADS category may help optimize the management of HCC patients.
  • The impact of the COVID-19 pandemic on the provision of instrumental help by older people across Europe Mon, 28 Nov 2022 06:00:00 -0500
    The outbreak of the COVID-19 pandemic in early 2020 introduced new challenges to social cohesion across Europe. Epidemiological control measures instituted in almost all European countries have impacted the possibility to provide help to others. In addition, individual characteristics contributed to whether individuals were able and willing to provide help to or receive help from others. Against this background, we focus on how private support networks of individuals aged 50 years and older...
  • Impact of COVID-19 on postgraduate medical education: Cross sectional survey from an Indian Medical College Mon, 28 Nov 2022 06:00:00 -0500
    CONCLUSION: COVID-19 pandemic and its effects on medical education are long lasting. A comprehensive approach is required to rebuild the medical education curriculum, inculcating both traditional and newer virtual methods of education. A consistent support in academics and overall growth needs to be provided to medical postgraduate residents who have been the first line fighters in face of the massive disaster compromising their basic needs and education.
  • Brain microstructural changes and fatigue after COVID-19 Mon, 28 Nov 2022 06:00:00 -0500
    CONCLUSIONS: Quantitative d-MRI detected changes in the WM microstructure of patients recovering from COVID-19. This study suggests a possible brain substrate underlying the symptoms caused by SARS-CoV-2 during medium- to long-term recovery.
  • A survey of health status of healthcare providers in a square cabin hospital during the new corona omicron outbreak: A cross-sectional study Mon, 28 Nov 2022 06:00:00 -0500
    CONCLUSION: In the case of an unexpected pandemic, the mental health of healthcare providers is not optimistic. This situation still exists more than 2 years after the global outbreak of the COVID-19 pandemic. Therefore, the physical and mental health of long-term healthcare providers working in a square cabin hospital still needs monitoring.
  • Research on the influence of indoor thermal environment and activity levels on thermal comfort in protective clothing Mon, 28 Nov 2022 06:00:00 -0500
    With the outbreak of infectious diseases such as Corona Virus Disease 2019, medical staff work intensively in isolated plots, medical disposable protective clothing (MDPC) has poor air condition and humidity permeability, which seriously reduces the thermal comfort of medical staff. In this paper, the effect of indoor thermal environment and activity levels on thermal comfort inside MDPC was studied by experiment. Five parts of the body were measured inside MDPC and the appropriate movements...
  • Lesion Location Predicts Early Neurological Deterioration in Single Subcortical Infarction Mon, 28 Nov 2022 06:00:00 -0500
    Background- A certain number of patients with single subcortical small infarction (SSSI) in the lenticulostriate artery (LSA) territory present with early neurological deterioration (END). Objective-We sought to identify more specific predicting imaging marker for END in lenticulostriate SSSI patients. Methods-We screened patients in a prospective hospital-based registry of stroke in the first Affiliated Hospital of Zhengzhou University from January 2015 to December 2020. Lesion locations were...
  • Predicting protein function and orientation on a gold nanoparticle surface using a residue-based affinity scale Sun, 27 Nov 2022 06:00:00 -0500
    The orientation adopted by proteins on nanoparticle surfaces determines the nanoparticle's bioactivity and its interactions with living systems. Here, we present a residue-based affinity scale for predicting protein orientation on citrate-gold nanoparticles (AuNPs). Competitive binding between protein variants accounts for thermodynamic and kinetic aspects of adsorption in this scale. For hydrophobic residues, the steric considerations dominate, whereas electrostatic interactions are critical...
  • A data-driven model-free adaptive controller with application to wind turbines Sun, 27 Nov 2022 06:00:00 -0500
    A data-driven controller is presented in this paper, which stems from the well known model-free adaptive control approach based on an equivalent linearized dynamical model of the plant. Inspired by the recent paper (Liu and Yang, 2019), the output tracking problem is here solved by a data-driven adaptive sliding-mode controller simultaneously ensuring prescribed performance constraints. To allow a rigorous stability analysis, the sliding variable, and the consequently derived controller, have...
