Determination of the Physical and Chemical Properties and Volatile Aroma Components Distribution of Geographically Indicated Besni Grape Raisin

Food Science &Nutrition, Volume 14, Issue 8, August 2026.
This study characterized the physical, chemical, and volatile aroma profiles of geographically indicated yellow and black Besni grapes harvested from the Besni and Gölbaşı districts of Adıyaman, Türkiye. The effects of on‐branch dehydration versus traditional direct sun drying were comprehensively evaluated.

Degradation of Seasonally Frozen Ground in the Three–River Source Region and Its Correlation Impact Within Precipitation–Runoff Process

International Journal of Climatology, Volume 46, Issue 10, August 2026.
This study reveals how climate change alters the water cycle in the Three Rivers Source region by degrading its important ‘solid groundwater’ (seasonally frozen ground). We found that runoff response varies by watershed and the role of permafrost decreases sharply, making water supply more dependent on rainfall and becoming increasingly vulnerable ...

Prediction of Soil Texture Distributions by using PLSR and Reflectance Spectroscopy

International Journal of Recent Technology and Engineering (IJRTE), 2019
The texture of soil i.e. Sand, Silt and Clay are the most important physical properties of soil for agricultural management. In the agricultural practices to increase the productivity of soil, moisture-holding capacity, aeration and to support the agronomic decisions the knowledge of soil texture is an essential task.

Managing Spectral Intensity Variations With In‐Line Fiber‐Optic High‐Volume Noncontact Raman Probes: A Strategy Exploration

Journal of Raman Spectroscopy, Volume 57, Issue 8, Page 1325-1338, August 2026.
Robust quantification in noncontact Raman sensing requires dedicated correction of working distance dependent background effects, while laser power variations are readily stabilized using internal reference signals. Chemically relevant Raman intensity can be preserved for bulk composition measurements, under variable laser power and working distance ...

Deep Soil Drying Increases Dryland Apple Tree's Eco‐Physiological Sensitivity to Atmospheric Drought

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract Dryland tree survival critically depends on deep soil water (DSW), particularly during dry spells. However, DSW is often limited and can be exhausted during periods of active tree growth, as recharge from precipitation is minimal. The eco‐physiological responses of trees to compound droughts (i.e., combined deep soil and atmospheric droughts ...

Robust estimation of key leaf traits from reflectance spectroscopy of herbarium specimens

Methods in Ecology and Evolution, Volume 17, Issue 8, Page 2364-2378, August 2026.
Abstract Community‐wide efforts to digitize herbarium specimens have facilitated novel uses of specimen data across scales. However, the need for destructive sampling has prevented large‐scale examination of foliar functional traits. We demonstrate that nondestructive reflectance spectra are an effective tool for estimating leaf traits from herbarium ...

A Novel Hybrid Approach to Deal with DVL Malfunctions for Underwater Integrated Navigation Systems

Applied Sciences, 2017
As a common device for underwater integrated navigation systems, Doppler velocity log (DVL) has the risk of malfunction. To improve the reliability of navigation systems, a hybrid approach is presented to forecast the measurements of the DVL while it ...

Climate change and crop resilience: harnessing metabolomics for predicting stress tolerance

New Phytologist, Volume 251, Issue 3, Page 975-995, August 2026.
Summarised methodology for metabolite biomarker discovery and genomic targets selection for those metabolites to predict high‐throughput phenotypic and agronomic traits of interest for direct uptake in breeding programmes. Summary Global warming is driving climate change to levels not experienced since the advent of agriculture, primarily due to ...
