Securing AI Systems: A Guide to Known Attacks and Impacts
Embedded into information systems, artificial intelligence (AI) faces security threats that exploit AI-specific vulnerabilities. This paper provides an accessible overview of adversarial attacks unique to predictive and generative AI systems. We identify eleven major attack types and explicitly link attack techniques to their impacts -- including information leakage, system compromise, and resource exhaustion -- mapped to the confidentiality, integrity, and availability (CIA) security triad. We…

Applications of Faà di Bruno's formula to partition traces
We revisit several partition-theoretic generating functions, including the theta quotients from Ramanujan's lost notebook, MacMahon's partition functions, and reciprocal sums of parts in partitions, through the lens of the classical Faà di Bruno formula. This approach offers a unified and natural reinterpretation of known results and provides a systematic framework for deriving new identities of a similar type.

ICE Is Using a New Facial Recognition App to Identify People, Leaked Emails Show
The new tool, called Mobile Fortify, uses the CBP system which ordinarily takes photos of people when they enter or exit the U.S., according to internal ICE emails viewed by 404 Media. Now ICE is using it in the field.

Remarks on the intersection of two quadrics
The article takes the formula for the integrable system defined by Beauville et al on the cotangent bundle of the intersection of two quadrics X, and interprets it in terms of rank 2 quasi parabolic Higgs bundles on the projective line. We then discuss aspects related to the geometric Langlands programme in this simple concrete context. We conclude with a description of the link with the recent paper of Benedetti et al identifying X and its integrable system in terms of invariant Spin(2g) bundl…

Spannender #Faktenfinder über "hochverarbeitete Lebensmittel":
"Durch die Kriterien der NOVA-Klassifikation kommt es zudem zu fragwürdigen Einteilungen, so die Experten. Beispielsweise werde unverpacktes Brot der Kategorie 3 zugeordnet, verpacktes Brot der Kategorie 4 - selbst bei identischen Zutaten. Denn zur Klassifizierung werden unter anderem auch die Art der Verpackung…

Warum hochverarbeitete Lebensmittel nicht automatisch ungesund sind
Je natürlicher, desto gesünder: Dieser Ernährungsmythos hält sich hartnäckig. Vor allem hochverarbeitete Lebensmittel stehen daher unter Generalverdacht. Dabei ist das aus wissenschaftlicher Sicht kaum haltbar.

Development and validation of an electron temperature-dependent interaction potential for silicon and copper for the use in atomistic simulations of laser ablation

Development and validation of an electron temperature-dependent interaction potential for silicon and copper for the use in atomistic simulations of laser ablation
Laser pulses with a duration of the order of femtoseconds lead to a strong excitation, heating and potentially to ablation of the irradiated material. During the time of strong excitation, the interaction of the atoms and thus the material dynamics can be strongly altered. To take this effect into account, an ip was developed for copper that takes the excitation of the electrons into account up to an electron temperature of 1.2 eV. Furthermore, several ways to identify non-thermal effects in De…

There are undoubtedly morally justified uses of facial recognition technology, but improving and refining these technologies directly enables racist policies.

Robust Inference with High-Dimensional Instruments
We propose a weak-identification-robust test for linear instrumental variable (IV) regressions with high-dimensional instruments, whose number is allowed to exceed the sample size. In addition, our test is robust to general error dependence, such as network dependence and spatial dependence. The test statistic takes a self-normalized form and the asymptotic validity of the test is established by using random matrix theory. Simulation studies are conducted to assess the numerical performance of …

Design and FPGA Implementation of WOMBAT: A Deep Neural Network Level-1 Trigger System for Jet Substructure Identification and Boosted $H\rightarrow b\bar{b}$ Tagging at the CMS Experiment
This thesis investigates the physics performance, trigger efficiency, and Field Programmable Gate Array (FPGA) implementation of machine learning (ML)-based algorithms for Lorentz-boosted $H\rightarrow b\bar{b}$ tagging within the CMS Level-1 Trigger (L1T) under Phase-1 conditions. The proposed algorithm, WOMBAT (Wide Object ML Boosted Algorithm Trigger), comprises a high-performance Master Model (W-MM) and a quantized, FPGA-synthesizable Apprentice Model (W-AM), benchmarked against the standar…
