Modeling Factors Associated With Diarrhea Caused by Cryptosporidium Species Using Machine Learning Methods

open access: yesJournal of Clinical Laboratory Analysis, EarlyView.
This study applies machine learning methods, specifically Random Forest and Bagged CART, to classify Cryptosporidium spp. infections among children and identify key risk factors. The Bagged CART model demonstrated superior sensitivity and predictive performance, highlighting household crowding and water source as the most influential determinants of ...

Raman Signature of the Wings of the Globe Skimmer Dragonfly: Pantala flavescens

open access: yesJournal of Raman Spectroscopy, EarlyView.
Raman spectroscopy is used to confirm the presence of aliphatic and aromatic hydrocarbons and related derivatives including aldehydes, halides, alcohols, acids, esters, and phenols on the wings of Pantala flavescens. The analysis indicates that wing‐surface lipid composition is largely consistent across the three main ecological zones in Ghana. Notably,

Manual of tropical bryology [PDF]

open access: yes, 2003
Bryophytes belong to the oldest land plants. They existed already in the Palaeozoic 300 mio years ago in forms which were hardly different from the extant species. They remained relatively unchanged with relatively low evolution rates (and are thus often

A review of the postharvest biochemical, biophysical and biological properties of 61 cultivars of North American pawpaw (Asimina triloba) fruit

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract Fruit from the North American pawpaw (Asimina triloba) is unfamiliar to many as a food crop and botanically unusual because it is the northernmost genus and only temperate member of the tropical Annonaceae family. It is the largest edible fruit native to North America.

Enhancing Soil Aggregation and Water Retention by Applying Kaolinite Clay to Post‐Tin‐Mined Land on Belitung Island, Indonesia

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Post‐mining sandy soils have low water retention, which causes soil particle separation and persistent soil erosion. Although organic matter is commonly used for soil restoration, it is lightweight, washes away during heavy rain, and decomposes under strong sunlight.
