Geometric Random Inner Products: A New Family of Tests for Random Number Generators [PDF]

, 2002
We present a new computational scheme, GRIP (Geometric Random Inner Products), for testing the quality of random number generators. The GRIP formalism utilizes geometric probability techniques to calculate the average scalar products of random vectors ...

On the Contribution of Unresolved Galactic Stars to the Diffuse Soft X-ray Background [PDF]

, 2001
Using stellar luminosity functions derived from ROSAT data, the contributions of Galactic stars to the diffuse X-ray background are calculated for ROSAT PSPC energy bands. The model follows that of Guillout et al. (1996), but uses ROSAT rather than {\it Einstein} data to determine the intrinsic luminosity distributions.

The Frequency‐Domain Lattice Boltzmann Method (FreqD‐LBM): A Versatile Tool to Predict the QCM Response Induced by Structured Samples

Advanced Theory and Simulations, EarlyView.
FreqD‐LBM simulates the oscillatory flow at the surface of a QCM‐D resonator in the presence of structured adsorbates. It derives shifts of frequency and bandwidth (equivalent to dissipation) on different overtones. Applications include rough surfaces, adsorbed rigid particles, adsorbed viscoelastic particles, spheres floating freely above the surface,

Understanding the Sampling Algorithm for Watt Spectrum [PDF]

Transactions of American Nuclear Society, Vol 130 (2024) 1005-1007
We provide details in understanding the Watt spectrum sampling method. The algorithm is given in "R12" from "3rd Monte Carlo Sampler" without detailed derivation. We rederive the algorithm by optimizating the sampling efficiency of the rejection method.

Artificial Intelligent‐Enhanced Metabolite Profiling for Intraoperative IDH1 Genotyping in Glioma Using an Orthogonally Responsive SERS Probe

Advanced Science, EarlyView.
This study presents a novel approach for intraoperative identification of the IDH1 genotype in glioma patients using a surface‐enhanced Raman scattering (SERS) probe to measure glutathione and hydrogen peroxide. By integrating AI‐driven deep learning algorithms, the method achieves rapid and accurate genotype differentiation, offering the potential to ...

Hyperfine Populations Prior to Muon Capture

, 1992
It is shown that the 1S level hyperfine populations prior to muon capture will be statistical when either target or beam are unpolarised independent of the atomic level at which the hyperfine interaction becomes appreciable.

Construction of accurate Kohn-Sham potentials for the lowest states of the helium atom: Accurate test of the ionization-potential theorem [PDF]

, 2004
Accurate local Kohn-Sham potentials have been constructed for the ground $1s^2 ^1S$ state and, in particular, for the lowest triplet $1s2s ^{3}S$ state of the helium atom, using electron densities from many-body calculations and the procedure of van Leeuwen and Baerends (Phys. Rev. A{\bf49}, 2138 (1994)).

Investigation of Opto‐magnetic Memory Effects in Antiferromagnetic CuMnAs Using Ultrafast Heat Dynamics and Quench Switching

Advanced Electronic Materials, EarlyView.
Using a pair of excitation laser pulses, this work examines functionalities of an antiferromagnet memory favorable for information processing, readily incorporating transient heat dynamics at sub‐nanosecond times, reminiscing the short‐term memory, and long‐term magnetic memory.

Impact of Fiber Morphology and Content on the Thermal Stability, and Mechanical Performance of Maple Wood Fiber‐Polypropylene Composites

Journal of Applied Polymer Science, EarlyView.
ABSTRACT In recent years, natural‐fiber‐reinforced polymers have gained significant attention due to their sustainability and enhanced properties. This study used Canadian maple wood fiber as reinforcement in a polypropylene (PP). Fiber length and fiber content are known as key factors affecting the properties of the composites.
