Novel Path Planning Algorithm for the Mobile Robot in Power Transformer Substation

International Transactions on Electrical Energy Systems
In response to the issue of low search efficiency caused by the large number of expanded nodes when mobile robots use traditional A∗ algorithm for path planning in complex environments, an improved A∗ algorithm based on four-way search has been proposed.

Estimation of Critical Resistive Leakage Current of polymer housed ZnO surge arrester by electro-thermal modelling

Journal of Electrical Systems and Information Technology, 2018
In this study, a MATLAB/Simulink software based electro-thermal model of the polymer housed, gapless, 60 kV ZnO surge arrester is used for estimating the ‘ Critical Resistive Leakage Current (CRLC)’.

Preferences of Pediatric Patients and Their Caregivers for Chemotherapy‐Induced Nausea and Vomiting Control Endpoints: A Mixed Methods Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Although not always achieved, complete chemotherapy‐induced nausea and vomiting (CINV) control is the conventional goal of CINV prophylaxis. In this two‐center, mixed‐methods study, we sought to understand the preferences of adolescent patients and family caregivers for CINV control endpoints.

Voltage sensors

Molecular Pharmacology
Widely distributed in all kingdoms of life, voltage sensors in the membrane serve important functions via their movements driven by changes in voltage across the membrane (membrane potential). A voltage sensor domain contains 4 transmembrane segments (S1-S4).

Intravitreal GD2‐Specific Chimeric Antigen Receptor T‐Cell Therapy for Refractory Retinoblastoma

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Effective treatments for advanced, treatment‐resistant retinoblastoma (RB) remain limited. GD2‐specific chimeric antigen receptor (CAR) T cells show potent antitumor activity with minimal toxicity but have not previously been evaluated in RB.

Bistable non-volatile elastic membrane memcapacitor exhibiting chaotic behavior

, 2011
We suggest a realization of a bistable non-volatile memory capacitor (memcapacitor). Its design utilizes a strained elastic membrane as a plate of a parallel-plate capacitor.

Outcomes of Live Virus Vaccination in Patients With Vascular Anomalies Being Treated With Sirolimus

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Live vaccination in patients with vascular anomalies (VA) receiving sirolimus remains controversial due to immunosuppressive effects and theoretical risks. Procedure This single‐center retrospective study included patients with VA less than 4 years old at the start of sirolimus therapy who were incompletely vaccinated.
