Updating the orbital ephemeris of the dipping source XB 1254-690 and the distance to the source [PDF]

, 2017
XB 1254-690 is a dipping low mass X-ray binary system hosting a neutron star and showing type I X-ray bursts. We aim at obtaining more accurate orbital ephemeris and at constraining the orbital period derivative of the system for the first time.

β‐Adrenergic Signaling Promotes Anti‐Tumor Immunity in TP53‐mutant Oral Squamous Cell Carcinoma

Advanced Science, EarlyView.
β‐adrenergic stimulation enhances anti‐tumor immunity in TP53‐deficient oral squamous cell carcinoma by inducing tumor‐derived secretion of CXCL10, which attracts and activates cytotoxic CD8+ T cells. The findings demonstrate that β‐adrenergic signaling alters tumor–immune interactions via CXCL10‐mediated paracrine activation, revealing a neuro‐immune ...

Minimum Distance Warning and Braking System for Vehicles

International Journal for Research in Applied Science and Engineering Technology, 2021
A vehicle distance measuring safety warning and braking system is disclosed having one or more distance measurement sensors measuring the distance from the driver's vehicle to a second vehicle immediately in front, the minimum distance between the vehicle and any object depends on the speed of the vehicle and here the speed of the vehicle is measured ...

Analysis of Train Signaling System Safety Distance

Chengshi guidao jiaotong yanjiu
[Objective] The current calculation of safety distance in the moving block signaling system does not consider adverse working conditions such as faults and low adhesion coefficients, resulting in poor authenticity and low precision in safety distance ...

Braking the Gas in the beta Pictoris Disk

, 2006
(Abridged) The main sequence star beta Pictoris hosts the best studied circumstellar disk to date. Nonetheless, a long-standing puzzle has been around since the detection of metallic gas in the disk: radiation pressure from the star should blow the gas ...

Onboard Model-based Prediction of Tram Braking Distance

IFAC-PapersOnLine, 2020
In this paper, we document design and a prototype implementation of a computational method for an onboard prediction of a breaking distance for a city rail vehicle|a tram. The method is based on an onboard simulation of tram braking dynamics. Inputs to this simulation are the data from a digital map and the estimated (current) position and speed, which

Cellular Identity Crisis: RD3 Loss Fuels Plasticity and Immune Silence in Progressive Neuroblastoma

Advanced Science, EarlyView.
Researchers discovered that therapy‐induced loss of RD3 protein in neuroblastoma triggers a dangerous shift: cancer cells become more stem‐like, invasive, and resistant to treatment while evading immune detection. RD3 loss suppresses antigen presentation and boosts immune checkpoints, creating an immune‐silent environment.

Velocity Optimization for Braking Energy Management of In-Wheel Motor Electric Vehicles

IEEE Access, 2019
This paper presents two braking regenerative energy optimization controllers for in-wheel motor electric vehicles. The first one is a velocity-tracking controller based on a model predictive control (MPC) method to recover the braking energy.
