Influence of Diaphragm Dynamics on Shock Wave Propagation in Double-Diaphragm Shock Tubes [PDF]

open access: yesarXiv
Shock tubes have become indispensable tools for advancing research across diverse fields such as aerodynamics, astrophysics, chemical kinetics, and industrial applications. The present study examines shock velocity variations in double-diaphragm shock tubes and their impact on flow dynamics at the end of the shock tube. Experiments were conducted using

Diagnosis of necrotic and non‐necrotic small bowel strangulation: The importance of intestinal congestion

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
CT of 141 patients with small bowel strangulation (SBS) was reviewed. Mesenteric edema and abnormal bowel wall thickening are prevalent in both non‐necrotic and necrotic SBS, indicating the primary pathology of SBS. While bowel hypo‐enhancement was detected in 76% of patients with necrotic SBS, it appeared in only 51% of those with non‐necrotic SBS ...

Design And Fabrication of Condenser Microphone Using Wafer Transfer And Micro-electroplating Technique [PDF]

open access: yesDans Symposium on Design, Test, Integration and Packaging of MEMS/MOEMS - DTIP 2008, Nice : France (2008), 2008
A novel fabrication process, which uses wafer transfer and micro-electroplating technique, has been proposed and tested. In this paper, the effects of the diaphragm thickness and stress, the air-gap thickness, and the area ratio of acoustic holes to backplate on the sensitivity of the condenser microphone have been demonstrated since the performance of

Interactive Haptic System with Multimodal Tactile Sensing and Hydraulic Feedback for Realistic Human–Machine Interaction

open access: yesAdvanced Intelligent Systems, EarlyView.
An interactive haptic system combining a robotic hand with a wearable tactile feedback device is presented. Driven by vision recognition, the robotic hand captures force and temperature data using multiple sensors and transmits the feedback to the user via hydraulic actuation.

Multiomics identifies the link between intratumor steatosis and the exhausted tumor immune microenvironment in hepatocellular carcinoma

open access: yesHepatology, EarlyView., 2022
Steatotic HCC can be diagnosed by MRI and forms a pro‐tumor immune microenvironment with high expression of PD‐L1, M2 polarization of macrophages and activation of CAFs, which may be a good target for combined immunotherapy. Abstract Background and Aims Immunotherapy has become the standard‐of‐care treatment for hepatocellular carcinoma (HCC), but its ...

Refining the adriamycin‐induced focal segmental glomerulosclerosis mouse model to improve reproducibility and animal welfare

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This study suggested the instability of Adriamycin (ADR) in aqueous solution as the main contributor to large ADR dose variations in literature of the ADR‐induced mouse model of focal segmental glomerulosclerosis (FSGS). We confirmed that freshly prepared ADR solution dosed at 10.5 mg/kg to be optimal in reliably producing FSGS pathology in BALB/c mice

Synthesis and Characterization of Fe‐Phthalocyanine‐Based Metal–Organic Framework

open access: yesAdvanced Physics Research, EarlyView.
A 2D layered material FePc‐MOF with Fe‐phthalocyanine backbone as a building unit is synthesized, which is a promising candidate for Lieb lattice. Lieb lattice is a type of Dirac materials that has been theoretically predicted to have a unique electronic structure for a long time, but it has never been synthesized as a real material.
