On log canonical divisors that are log quasi-numerically positive
, 2003 Let $(X, \Delta)$ be a four-dimensional log variety that is projective over the field of complex numbers. Assume that $(X, \Delta)$ is not Kawamata log terminal (klt) but divisorial log terminal (dlt).

Precise Real‐Time Measurement of Liquid Viscosity Using Digital Video Data
Advanced Intelligent Systems, Volume 7, Issue 12, December 2025.Frame‐by‐frame image similarity analysis is employed to obtain the viscosity of moving liquids in real time. The method allows for online implementation even in harsh environments, replacing complex and invasive experiments. Quantitative knowledge of liquid viscosity is of fundamental importance in many areas of materials synthesis and processing ...

The interacting effects of climate and land‐cover change on bird communities in the United States
Ecography, Volume 2025, Issue 12, December 2025.Human activities exert numerous, simultaneous pressures on biodiversity. In particular, land cover and climate change are major contributors to biodiversity change, and these pressures can vary spatiotemporally and interact in complex ways. Adding to this complexity is the necessity to evaluate a suite of biodiversity metrics in concert, given that ...

On the Coupling of Gravitons to Matter
, 1999 Using relationships between open and closed strings, we present a construction of tree-level scattering amplitudes for gravitons minimally coupled to matter in terms of gauge theory partial amplitudes.

Continuous‐Wave (CW) Photo‐CIDNP NMR Spectroscopy: A Tutorial
Magnetic Resonance in Chemistry, Volume 63, Issue 12, Page 1020-1034, December 2025.ABSTRACT Photo‐chemically induced dynamic nuclear polarisation (photo‐CIDNP) is a nuclear spin‐selective magnetic resonance phenomenon that has traditionally been used to mechanistically study chemical reactions involving the (transient) formation of radical molecular species, extract EPR observables of short‐lived radicals, probe biomolecular ...

EURASIP Journal on Advances in Signal Processing, 2003 Limiting the decrease in performance due to acoustic environment changes remains a major challenge for continuous speech recognition (CSR) systems. We propose a novel approach which combines the Karhunen-Loève transform (KLT) in the mel-frequency ...
