Abstract:
Angioimmunoblastic T-cell lymphoma (AITL) is a T-cell lymphoma of follicular helper T-cell origin. Histologically, neoplastic T-cells proliferate to form clusters adjacent to or between arborizing high endothelial venules (HEVs). HEVs in normal lymph nodes express sulfated glycans called peripheral lymph node addressin (PNAd); however, it remains unclear whether PNAd is also expressed on HEVs in AITL. Furthermore, although it is widely accepted that HEVs are conspicuous in AITL due to their proliferation, quantitative histological support for this concept is lacking. To investigate these issue

Abstract Chemokine receptor signaling is critical for lymphocyte trafficking across high endothelial venules (HEVs), but the exact mode of action of individual chemokines expressed in the HEVs is unclear.

Abstract:
HELVIS (Hybrid Electric Vehicle In Low Scale) is a mini-HEV platform used on the research of HEVs (Hybrid Electric Vehicles), through which students of all degrees have the opportunity to be introduced to the universe that surrounds HEVs in many aspects. In this work the HELVIS-Sim is presented. HELVIS-Sim is a full dynamic & kinematic vehicular simulator for the HELVIS platform, consisting of a Simulink™ environment through which the states of a large number of variables related to the vehicle can be observed and analyzed. Specially in this paper, the focus is in the control of HELVIS EDS

<title>ABSTRACT</title> <p>Most hybrid electric vehicle (HEV) applications require the utilization of electric motors that have high torque/power density, high efficiency, a wide speed range and reliability. Interior permanent magnet (IPM) synchronous motors comprised of rare-earth magnet material is the most common electric motor class used for HEVs. However, recent fluctuations in the rare-earth magnet pricing and availability demands the search for zero rare-earth motor topologies as an alternative to IPM for use in HEVs. Switched reluctance machines (SRMs) are rare-earth

Abstract:
The Kingdom of Saudi Arabia (KSA) is committed to transitioning towards a diversified, low-carbon economy, necessitating the decarbonization of its road freight sector, which is a significant source of domestic energy consumption and greenhouse gas (GHG) emissions. This study addresses the critical need to evaluate and compare the life cycle climate impacts of current and alternative truck powertrain technologies within KSA. We conducted a comparative life cycle assessment (LCA) of various truck powertrains, including internal combustion engine vehicles (ICEVs), hybrid electric vehicles (HEVs)

Abstract:
Analyzing the environmental performance of alternative vehicle technologies in the current energy landscape of the Kingdom of Saudi Arabia (KSA) is very important given their expected role in future transportation systems. This study presents a comprehensive life cycle assessment (LCA) of sedans and sport utility vehicles (SUVs) powered by different propulsion systems to analyze their environmental performance in the KSA context. The LCA examines multiple impact categories, with a particular focus on global warming potential (GWP). The results reveal that hybrid electric vehicles (HEVs), fuel

Abstract:
Electric vehicle (EV) transmission technology—crucial for battery electric vehicles (BEVs) and hybrid electric vehicles (HEVs)—is developing quickly and customers want good performance at a low cost. Single-speed gearboxes are popular in electric drive systems due to their simple and cost-effective configuration. However, multispeed gearboxes are being taken to market due to their higher low-speed torque, dynamic performance, and energy efficiency. Unsettled Technology Areas in Electric Propulsion Systems reviews the economic drivers, existing techniques, and current challenges of EV transmiss
