The limits of AI for authoritarian control

American Journal of Political Science, EarlyView.
Abstract An emerging literature suggests that artificial intelligence (AI) can greatly enhance autocrats' repressive capabilities. This paper argues that while AI presents a powerful new tool for authoritarian control, its effectiveness is constrained by the very repressive institutions it is designed to serve.

Assessing the Vulnerability of an Inuit Archaeological Site in a Changing Periglacial Environment: A Novel Multimethod Geophysical Approach in Arctic Geoarchaeology

Archaeometry, EarlyView.
ABSTRACT With northern regions warming at twice the global rate, assessing the state of archaeological sites in these areas is critically important. In this study, we used a multimethod geophysical approach (ERT, GPR, and EMI) to characterize the current geocryological conditions of an Inuit archaeological site on South Aulatsivik Island (Labrador ...

Exploring a Subpopulation of MASLD Associated With New Onset of CKD Using Supervised Clustering Techniques

Hepatology Research, EarlyView.
The supervised clustering of metabolic dysfunction‐associated steatotic liver disease (MASLD) using a SHapley Additive exPlanations (SHAP)‐converted matrix reveals distinct subpopulations that improved risk stratification for new onset of chronic kidney disease (CKD).

Evaluation of low noise and robust amplifier topologies using GaN technology for X-band radar or telecom applications

In order to increase telecommunication data rates and enhance the precision and range of modern radar systems, improving the noise factor of a communication link has become crucial. As demonstrated by the FRIIS formula, the noise factor of a reception architecture is mainly determined by the noise factor of the first stage.

Dementia‐Friendly Hospital—The Perspective of Professional Dementia Experts

Journal of Clinical Nursing, EarlyView.
ABSTRACT Aim To investigate the professional dementia experts' understanding of a dementia‐friendly hospital to identify its characteristics. Design We used a qualitative design embedded in a case study. A total of 16 semi‐structured expert interviews were conducted with 17 professional dementia experts. Using inductive content analysis, the interviews
