Large Anomalous Hall Effect at Room Temperature in a Fermi-Level-Tuned Kagome Antiferromagnet
The recent discoveries of surperisingly large anomalous Hall effect in chiral antiderromagnets have triggered extensive research efforts in various fields, ranging from topological condensed-matter physics to antiferromagnetic spintronics, and energy harvesting technology. However, such AHE-hosting antiferromagnetic materials are rare in nature. Herein, we demonstrate that Mn2.4Ga, a Fermi-level-tuned kagome antiferromagnet, has a large anomalous Hall conductivity of about 150 Ω-1cm-1 at room …

Visual Hallucination: Definition, Quantification, and Prescriptive Remediations
The troubling rise of hallucination presents perhaps the most significant impediment to the advancement of responsible AI. In recent times, considerable research has focused on detecting and mitigating hallucination in Large Language Models (LLMs). However, it's worth noting that hallucination is also quite prevalent in Vision-Language models (VLMs). In this paper, we offer a fine-grained discourse on profiling VLM hallucination based on two tasks: i) image captioning, and ii) Visual Question A…

Ympäristövaarallinen lentoliikenne on näemmä aika hyvin saatu vähenemään, kun Tampereen Härmälän lentoasemakin näyttää ihan autiolta.
Näinä aikoina tarvitaan turvallisuuden tunnetta antavaa nostalgiaa, joten kuva on otettu kameraohjelmani EGA-moodissa (16 väriä, 320 x 200 resoluutio)

Lossless Spin-Orbit Torque in Antiferromagnetic Topological Insulator MnBi$_2$Te$_4$
We formulate and quantify the spin-orbit torque (SOT) in intrinsic antiferromagnetic topological insulator $\rm MnBi_2Te_4$ of a few septuple-layer thick, which exhibits conspicuous layer-resolved characteristics. Contrary to known current-induced torques, the SOT in insulating $\rm MnBi_2Te_4$ is driven by an electric field (or voltage). We further study the SOT-induced magnetic resonances, where in the tri-septuple-layer case we identify a peculiar exchange mode that is blind to microwaves bu…

As the world prepares for future and ongoing global health threats from RNA viruses such as the SARS-CoV-2 pandemic,
breakthrough advances in antiviral development are becoming a critical weapon in the fight against these infectious diseases.
At the heart of this innovation is the exploration of CRISPR/Cas13 systems,
which are known for their programmable capabilities to manipulate RNAs and have become indispensable tools for various RNA targeting applications.
Howeve…

Cas13d-NCS: A game-changer in RNA virus defense
The rise of RNA viruses like SARS-CoV-2 highlights the need for new ways to fight them. RNA-targeting tools like CRISPR/Cas13 are powerful but inefficient in the cytoplasm of cells, where many RNA viruses replicate.

Der #express lohnt. Die "Zeitung für sozialistische Betriebs- und Gewerkschaftsarbeit", hier die Nr. 02/2024, bietet u.a. eine Kritik des #Antifeminismus und Ausschnitte aus der Graphic Novel von #BarbaraYelin

express 2/2024 erschienen! - express
Geneigte Leserinnen und Leser, traditionell ist die Februar-Ausgabe des express geprägt von feministischen und queeren Posi­tionierungen und Beiträgen. Mit der Tradition ist das so eine Sache: Man könnte sie für reine Makulatur halten, denn wir machen das natürlich, weil die Februar-Ausgabe die am 8. März aktuelle ist. Und uns ist sehr bewusst, dass eine Betonung des Feminismus am oder zum 8. März nur ein welkes Feigenblättchen wäre.

Observation of unconventional van der Waals multiferroics near room temperature
The search for two-dimensional (2D) van der Waals (vdW) multiferroics is an exciting yet challenging endeavor. Room-temperature 2D vdW few-layer multiferroic is a much bigger insurmountable obstacle. Here we report the discovery of an unconventional 2D vdW multiferroic with out-of-plane ferroelectric polarization and long-range magnetic orders in trilayer NiI2 device from 10 K to 295 K. The evolutions of magnetic domains with magnetic field, and the evolutions between ferroelectric and antiferr…
