Mapping hydrothermally altered rocks in the Northern Grapevine Mountains, Nevada and California with the airborne imaging spectrometer [PDF]

open access: yes
Seven flightlines of Airborne Imaging Spectrometer (AIS) data were analyzed for an area of hydrothermally altered rocks. The data were reduced to reflectance relative to an average spectrum, and an automated procedure was used to produce a color coded ...

The Use of AIS Data for Identifying and Mapping Calcareous Soils in Western Nebraska [PDF]

open access: yes, 1985
The identification of calcareous soils, through unique spectral responses of the vegetation to the chemical nature of calcareous soils, can improve the accuracy of delineating the boundaries of soil mapping units over conventional field techniques.

AI and Healthcare Data

open access: yes
The availability of data is a condition for the development of AI. This is no different in the context of healthcare-related AI applications. Healthcare data are required in the research, development, and follow-up phases of AI. In fact, data collection is also necessary to establish evidence of compliance with legislation.

Small Strokes, Big Impact: Excessive Mortality After Acute Ischemic Stroke in Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Background Acute ischemic stroke (AIS) in those with Parkinson's disease (PD) is a growing healthcare burden but mortality studies are significantly lacking. Objective To map short‐ and long‐term survival, stratified by relevant comorbidities and stroke characteristics.

Preliminary Analysis of AIS Spectral Data Acquired from Semi-arid Shrub Communities in the Owens Valley, California [PDF]

open access: yes, 1985
Spectral characteristics of semic-arid plant communities using 128 channel airborne imaging spectrometer (AIS) data acquired on October 30, 1984. Both field and AIS spectra of vegetation were relatively featureless and differed from substrate spectra ...

Predicting Destinations by Nearest Neighbor Search on Training Vessel Routes

open access: yes, 2018
The DEBS Grand Challenge 2018 is set in the context of maritime route prediction. Vessel routes are modeled as streams of Automatic Identification System (AIS) data points selected from real-world tracking data.

What Role Does the Central Nervous System Play in Refractory LUTS, and What Are the Therapeutic Implications? ICI‐RS 2025

open access: yesNeurourology and Urodynamics, EarlyView.
ABSTRACT Aims While many patients with lower urinary tract symptoms (LUTS) improve by treating peripheral causes, a substantial proportion continue to experience symptoms despite apparently successful interventions. Central nervous system (CNS) mechanisms could potentially contribute to persisting symptoms after the initial peripheral cause has been ...
