Experimental and theoretical evaluation of TCC connections with inclined self-tapping screws

, 2017
Timber-concrete composite (TCC) structures have become a wide-spread technique to realize new composite floors or improve existing ones. The key-point to guarantee adequate mechanical performance to these composite structures is the use of connectors ...

How Bots Threaten Democracy by Misrepresenting Actors and Ideas: The Case of the 2022 Swedish Election

Scandinavian Political Studies, Volume 49, Issue 4, November 2026.
ABSTRACT Online democratic discourse faces threats from diverse forms of information manipulation, including disinformation campaigns and foreign influence operations. Among these, political bots represent a covert and scalable threat, infiltrating online debates, amplifying select viewpoints, and distorting perceptions of public opinion.

Evaluating Harm Reduction Advice From Large Language Models

Drug and Alcohol Review, Volume 45, Issue 7, November 2026.
ABSTRACT Introduction Large language models (LLM) and generative Artificial Intelligence are increasingly providing health information. We have applied a novel method to evaluate the harm reduction information generated by popular LLMs. We focused on the filtration of oral medications for injection and the availability of local harm reduction services.

Direct Growth of 2D Bilayers on Au(111) for Low‐Coercive Sliding Ferroelectricity

Advanced Materials, Volume 38, Issue 56, 8 October 2026.
Controlled CVD growth of stacking‐defined bilayer ReS2 on Au(111) enables parallel‐stacked bilayers with intrinsic sliding ferroelectricity, a strong piezoelectric response, and an ultralow coercive voltage. Atomic‐resolution imaging and in situ measurements further reveal the decisive role of clean interfaces in achieving low‐barrier ferroelectric ...
