Thinking Outside the Rocks: Subsurface Water Storage, Topography, and Land Cover Are Key Modulators of Large‐Scale Riverine Dissolved Silicon Dynamics

Geophysical Research Letters
Riverine dissolved silicon (DSi) dynamics reflect integrated geologic, hydrologic, climatic, and ecological controls. We compiled annual DSi data for 337 rivers across four continents and trained interpretable machine‐learning models to predict ...

A machine learning approach on the investigation of the scale dependent relation of CAPE and precipitation

Meteorologische Zeitschrift, 2023
The temporal and spatial scale dependent relation of Convective Available Potential Energy (CAPE) and precipitation is investigated. Using the COSMO-REA6 data set, we ask which of the standard machine learning algorithms: perceptron, support vector ...

Psychometric properties of the Depressive Symptom Index-Suicidality Subscale (DSI-SS) in an adult psychiatric sample.

Psychological Assessment, 2021
The Depressive Symptom Index-Suicidality Subscale (DSI-SS) is a four-item self-report measure of suicidal ideation severity widely used across research and clinical contexts. However, the psychometric properties of the English-language version of the DSI-

Tidal variation modulates the dissolved silicate behavior and exchange flux across the semi-enclosed bay‐coastal water continuum, China

Frontiers in Marine Science, 2023
Coastal water is the key transition zone for the circulation and transport of nutrients. Their role in transporting nutrients is important to understanding global dissolved silicate (DSi) cycles and sources of nutrients supporting the biological pump and

Global drought monitoring with drought severity index (DSI) using Google Earth Engine

Theoretical and Applied Climatology, 2021
Unlike most disasters, drought does not appear abruptly. It slowly builds over time due to the changes in different environmental and climatological factors.

استفاده از نگار DSI به منظور تعیین ناهمسان‌گردی مخزن و جهت بیشینه تنش درجا [PDF]

Pizhūhish-i Naft, 2015
ناهمسان‌گردی نشان دهنده تغییر یک یا چند خاصیت از ماده بر حسب جهت است. تعیین دقیق ناهمسان‌گردی در مطالعات ژئوفیزیک اکتشافی، ژئوفیزیک مخزن، شناسایی مسیر مناسب برای حفاری چاه و جلوگیری از بروز مشکلاتی نظیر مشکل تولید ماسه بسیار مهم است. ابزار DSI کندی امواج

AIEgens assisted label free DNA supersandwich immunoassay for ultrasensitive α-fetoprotein detection

Giant, 2022
The traditional enzyme-linked immunosorbent assay has been widely applied in the field of protein detection. Nevertheless, the detecting performance suffers from high background. Herein, we choose label free molecules of aggregation-induced emission (AIE)

Role of Marginal Seas in Deep Ocean Regeneration of Dissolved Silica: A Case Study in the Marginal Seas of the Western Pacific

Frontiers in Marine Science, 2022
Deep ocean regeneration of dissolved silica (DSi) is an essential part of the ocean silica cycle and is driven by a complex series of biogeochemical processes. Here we compare the distributions of DSi and other environmental parameters in several western

Sand Dunes Spectral Index Determination Using Machine Learning Model: Case study of Baiji Sand Dunes Field Northern Iraq

Iraqi Geological Journal, 2022
Monitoring the propagation of dunes is essential for natural hazard management. Accurate dunes mapping is critical in this situation. Landscape elements such as vegetation, water, dunes, and built-up are commonly separated using spectral indices.

Practical consequences of digital sequence information (DSI) definitions and access and benefit‐sharing scenarios from a plant genebank’s perspective

Plants, People, Planet, 2021
It is currently discussed whether the use of digital sequence information (DSI) on genetic resources would need to be subject to access and benefit‐sharing obligations, like the use of genetic resources.
