Problem of the reference height of the projectile trajectory as a reduced meteo-ballistic weighting factor

open access: yesDefence Technology, 2014
This paper deals with the issue of preparation of the aiming angles with the use of tabular firing tables and needed determination of the ballistic elements μB (ballistic wind wB, wxB, wZB, ballistic (virtual) temperature τB, ballistic density ρB) from ...

Orientation‐Engineered PtTe2 Schottky FETs: Quantum Transport Insights for Dopant‐Free Advanced Technology Nodes

open access: yesAdvanced Electronic Materials, EarlyView.
Monolayer PtTe2 enables dopant‐free Schottky FETs through its thickness‐dependent electronic transition. Quantum transport simulations show that crystallographic orientation strongly influences device performance, with Γ–M transport delivering higher drive current, lower leakage, and improved switching behavior.

Smart Denture with Embedded Thin‐Film Temperature Sensors Patterned by Femtosecond Laser Pulse for Elderly Healthcare

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
We demonstrate the direct‐laser patterning of a gold thin film on polymethyl methacrylate to fabricate a temperature sensor for dentures. The temperature sensor‐embedded smart dentures are evaluated in an oral environment, enabling in‐situ monitoring for elderly healthcare.
