Comparative Studies on the Structure and Biological Activities of Two New Polysaccharides From Tricholoma flavovirens (TF‐P) and Trametes versicolor (TV‐P)

Food Frontiers, EarlyView.
Two water‐soluble polysaccharides were isolated and purified from Tricholoma flavovirens (TF‐P) and Trametes versicolor (TV‐P), respectively. The structures of the two polysaccharides were identified by combining GPC, FT‐IR, HPLC, GC–MS, and NMR, and the structure–activity relationship has also been studied using immune cells and tumor cells. TV‐P with

Measuring the Default Risk of Small Business Loans: Improved Credit Risk Prediction Using Deep Learning

Journal of Forecasting, EarlyView.
ABSTRACT This paper proposes a multilayer artificial neural network (ANN) method to predict the probability of default (PD) within a survival analysis framework. The ANN method captures hidden interconnections among covariates that influence PD, potentially leading to improved predictive performance compared to both logit and skewed logit models.

Autoencoding Raman Spectra to Predict Analyte Concentrations

Journal of Raman Spectroscopy, EarlyView.
An autoencoder‐based machine learning regression model was developed using datasets from nuclear and biopharmaceutical industries, utilising spatial heterodyne spectrometers under spontaneous and resonance conditions. This study focuses on the impact of small data volumes on data augmentation and architecture designs.

LIGHT ABERRATION IN OPTICAL ANISOTROPIC SINGLE-AXIS MEDIUM

East European Journal of Physics, 2017
The entrainment of the light flux by a uniaxial anisotropic medium and its influence on the measurement of stellar aberration are analyzed. The influence of the entrainment of the light flux by an isotropic medium on the measurement of stellar aberration

Occurrence of natural tree cavities suitable for nesting wood ducks across South Carolina forest types

The Journal of Wildlife Management, EarlyView.
Although evidence suggests >90% of the North American wood duck population nests in natural tree cavities, few studies have investigated the occurrence of these cavities across their southern breeding range. We aimed to determine forest and tree characteristics associated with the presence of cavities and cavities suitable for wood duck nesting and our
