Time-Varying Fine-Structure Constant Requires Cosmological Constant [PDF]
Modern Physics Letters A, 1999 Webb et al. presented preliminary evidence for a time-varying fine-structure constant. We show Teller's formula for this variation to be ruled out within the Einstein-de Sitter universe, however, it is compatible with cosmologies which require a large ...

Research on Time Constant Test of Thermocouples Based on QNN-PID Controller [PDF]
SensorsThe aim of this study is to solve the problem of it being difficult to obtain quantitative step signals when testing the time constant of thermocouples using the laser excitation method, thereby restricting the accuracy and repeatability of the test of ...

Time-constant absolute effect measures for time-to-event outcomes [PDF]
BMC Medical Research MethodologyBackground Reporting treatment effects from clinical trials on both relative and absolute scales is crucial. While absolute measures like the Number Needed to Treat (NNT) are well-established for binary outcomes, their calculation for time-to-event ...

CTIDH: faster constant-time CSIDH
Transactions on Cryptographic Hardware and Embedded Systems, 2021 This paper introduces a new key space for CSIDH and a new algorithm for constant-time evaluation of the CSIDH group action. The key space is not useful with previous algorithms, and the algorithm is not useful with previous key spaces, but combining the ...

Oxygen uptake and heart rate kinetics of body mass-based squat exercise in children and adults
Journal of Physical Fitness and Sports Medicine, 2021 This study aims to clarify oxygen uptake (VO2) and heart rate (HR) kinetics of body mass-based squat exercise (SQBM) with relation to age. Fourteen healthy adults and 19 healthy children performed SQBM 200 times as well as an incremental loaded bicycle ...

Journal of Microwaves, Optoelectronics and Electromagnetic Applications, 2021 This paper addresses the influence of the primary and secondary resistances on the behavior of minor hysteresis loops when the electromagnetic device is fed by three-level PWM (pulse width modulation) voltage. To study the device transferring energy to a
