description: The group embeddings used in orbifolding the AdS/CFT correspondence to arrive at quiver gauge field theories are studied for both supersymmetric and non-supersymmetric cases. For an orbifold AdS5 × S5/Γ the conditions for embeddings of the finite group Γ in the SU(4) ~ O(6) isotropy of S5 are stated in the form of consistency rules, both for Abelian and Non-Abelian Γ.
PIXHELL Attack: Leaking Sensitive Information from Air-Gap Computers via `Singing Pixels'
Creators: name: Guri, Mordechai
Publisher: name: arXiv
Year: 2024
Subjects: subject: Cryptography and Security (cs.CR)
subject: FOS: Computer and information sciences

description: Air-gapped systems are disconnected from the Internet and other networks because they contain or process sensitive data. However, it is known that attackers can use computer speakers to leak data via sound to circumvent the air-gap defense. To cope with this threat, when highly sensitive data is involved, the prohibition of loudspeakers or audio hardware might be enforced. This measure is known as an `audio gap'.
 In this paper, we present PIXHELL, a new type of covert channel attack allowing hackers to leak information via noise generated by the pixels on the screen. No audio hardware or loudspeakers is required. Malware in the air-gap and audio-gap computers generates crafted pixel patterns that produce noise in the frequency range of 0 - 22 kHz. The malicious code exploits the sound generated by coils and capacitors to control the frequencies emanating from the screen. Acoustic signals can encode and transmit sensitive information. We present the adversarial attack model, cover related work, and provide technical background. We discuss bitmap generation and correlated acoustic signals and provide implementation details on the modulation and demodulation process. We evaluated the covert channel on various screens and tested it with different types of information. We also discuss \textit{evasion and stealth} using low-brightness patterns that appear like black, turned-off screens. Finally, we propose a set of countermeasures. Our test shows that with a PIXHELL attack, textual and binary data can be exfiltrated from air-gapped, audio-gapped computers at a distance of 2m via sound modulated from LCD screens.

description: The 2-nitrophenol and 4-nitrophthalonitrile reagents were mixed in the presence of potassium carbonate in dimethylformamide (DMF) under N2 at room temperature. Then, by adding thymol(5-methyl-2-isopropylphenol) and continuing the reaction, 4-(2-(2-isopropyl-5-methylphenoxy)phenoxy)phthalonitrile was obtained. Zinc phthalocyanine (4) was formed from the reaction of ZnCl2 and 4-(2-(2-isopropyl-5-methylphenoxy)phenoxy)phthalonitrile (3) at 190 °C. Both compounds were soluble in most organic solvents. Compounds 3 and 4 were characterized by mass, infrared, electronic absorption and nuclear magnetic resonance spectroscopies. The concentration–absorption relationship of 4 was examined by UV spectroscopy. The photophysical and photochemical properties of 4 were investigated. The geometry-optimized structures of 4 were investigated with the DFT approach, B3PW91/6-31G (d,p), and B3LYP/LanL2DZ basis set. Energy properties, first order hyperpolarizability, and Fukui function calculations were also performed. Natural bond orbital analysis was performed to explain the charge transfer (or) charge delocalization due to intramolecular interactions in phthalocyanine.

description: We report on the engineering of a non-dispersive (flat) energy band in a geometrically frustrated lattice of micro-pillar optical cavities. By taking advantage of the non-hermitian nature of our system, we achieve bosonic condensation of exciton-polaritons into the flat band. Due to the infinite effective mass in such band, the condensate is highly sensitive to disorder and fragments into localized modes reflecting the elementary eigenstates produced by geometric frustration. This realization offers a novel approach to studying coherent phases of light and matter under the controlled interplay of frustration, interactions and dissipation.

description: We show that it is possible to construct supersymmetric three-generation models of Standard Model gauge group in the framework of non-simply-connected elliptically fibered Calabi-Yau, without section but with a bi-section. The fibrations on a cover Calabi-Yau, where the model has 6 generations of SU(5) and the bundle is given via the spectral cover description, use a different description of the elliptic fibre which leads to more than one global section. We present two examples of a possible cover Calabi-Yau with a free involution: one is a fibre product of rational elliptic surfaces dP9; another example is an elliptic fibration over a Hirzebruch surface. There we give the necessary amount of chiral matter by turning on in the bundles a further parameter, related to singularities of the fibration and the branching of the spectral cover.

description: Three ruthenium-bipyridine complexes (1–3) carrying acetylpyridine ligand unit were synthesized in methanol via the reaction of [RuCl2(bpy)2] with corresponding acetylpyridine (2-, 3-, and 4-acpy). Obtained complexes were characterized by (1H and 13C) NMR and IR spectroscopy, MS spectrometry, UV‒vis spectrophotometry, and cyclic voltammetry. Their structural characterization revealed bidentate coordination mode for 2-acpy while 3- and 4-acpy acted as monodentate ligands. The electrochemical profile of newly synthesized compounds was investigated by cyclic voltammetry which confirmed their electrochemical activity. Voltammetric responses within the −1.20 < Ep < 1.50 V range of potentials were summarized in two major events: Ru(II)→Ru(III) oxidation spotted at app. ΔEp = 0.65 V and successive reductions of bpy units located from ‒0.79 V to 0.47 V (vs. Ag/AgCl (3 M) electrode). The DNA-binding activity of the complexes was evaluated by both UV‒vis spectrophotometry and cyclic voltammetry indicating DNA-intercalation with a slight contribution of electrostatic interactions. Furthermore, antimicrobial activity was tested against bacterial and fungal strains, for which moderate activity was observed. Assessment of in vitro toxicity against freshly hatched nauplii of Artemia salina as well as radical scavenging capacity was evaluated. The test compounds showed neither toxicity nor antioxidant activity.

Finally, a model with two right-handed neutrinos and two Dirac texture zeros is described (FGY model) which can relate CP violation in leptogenesis to CP violation in long-baseline neutrino oscillations.

description: Oxido iron(IV) complexes are key intermediates in oxygenation reactions in biological systems. They can form during oxidation experiments with various oxidants such as oxygen, hydrogen peroxide, organoiodine compounds, or ozone. However, kinetic studies for these reactions are rare because the intermediates are usually labile. Here the results of a detailed investigation on the oxidation of iron(II) complexes with macrocyclic (e.g. TMC = tetramethylcyclam = 1,4,8,11-tetramethyl-1,4,8,11-tetraaza-cyclotetradecane) ligands are reported that provide a better understanding of the mechanisms of these reactions. For formation of the quite stable oxido iron complex with an amide derivative of TMC, activation parameters with ΔH‡ = 28 ± 4 kJ·mol−1 and ΔS‡ = −144 ± 15 J·mol−1·K−1 could be obtained that allowed postulation of an associative mechanism.

description: We present an end-to-end (equivalent) key recovery attack on the Dilithium lattice-based signature scheme, one of the winners of the NIST postquantum cryptography competition. The attack is based on a small side-channel leakage we identified in a bit unpacking procedure inside Dilithium signature generation. We then combine machine-learning based profiling with various algorithmic techniques, including least squares regression and integer linear programming, in order to leverage this small leakage into essentially full key recovery: we manage to recover, from a moderate number of side-channel traces, enough information to sign arbitrary messages. We confirm the practicality of our technique using concrete experiments against the ARM Cortext-M4 implementation of Dilithium, and verify that our attack is robust to real-world conditions such as noisy power measurements. This attack appears difficult to protect against reliably without strong side-channel countermeasures such as masking of the entire signing algorithm, and underscores the necessity of implementing such countermeasures despite their known high cost.

description: A novel 5,10,15-tris(5-bromo-2-thienyl),20(phenylcarboxy)porphyrin and its gallium derivative have been synthesized and fully characterized by various spectroscopic techniques and their respective photophysical and photochemical properties, such as the singlet oxygen quantum yield (ΦΔ), fluorescence quantum yield (ΦF) and triplet lifetime (τT) were determined. The complexes were conjugated to PEI_GQDs resulting is stable conjugates, owing to strong π–π stacking interaction between the PEI_GQDs and the porphyrins. PDT studies were carried out on these nanoconjugates and results obtained indicated they are suitable candidates for further in-depth PDT studies.

description: The dinuclear compound [Co2(Hatzc)2(H2O)6](NO3)2·4H2O containing the polytopic ligand Hatzc‒ = 3-amino-4H-1,2,4-triazole-5-carboxylate was synthesized and characterized. Single-crystal X-ray diffraction showed that two monoanionic N,O-chelating Hatzc‒ ligands bridge two Co(II) ions in a µ-N1,N2 fashion. Both Co(II) centers are further coordinated by three H2O ligands making up an octahedral coordination. A complex network of intra- and intermolecular O‒H···O and N‒H···O hydrogen bonding interactions characterize the structure. Hirshfeld surface analysis, ATR–FTIR, and FT-Raman spectroscopy in combination with density functional theory (DFT) calculation of vibrational modes confirm this multitude of H bonds. Thermogravimetric and differential thermal analysis experiments under an argon atmosphere in the temperature range of 25–900 °C showed thermal stability till about 100 °C and multi-step decomposition yielding Co2O3 at about 280 °C. The octahedral environment of Co(II) was confirmed by UV–vis absorption spectroscopy, which shows weak absorption bands at around 520 nm assignable to electronic d‒d transitions alongside with π‒π* transitions dominating the 250–350 nm range. Time-dependent DFT calculated excited states agree very well in terms of energy match with the observed transitions. The direct and indirect optical band gap values were determined using the Tauc plot method to 3.33 eV and 2.75 eV, respectively, indicating semiconducting properties.

description: Effective cybersecurity management requires significant automation to handle the complexity and volume of information involved. Traditional technologies with fixed implementations are often inadequate for combating security threats. Machine learning methods in AI offer a solution to this challenge. This paper presents an overview of various AI applications in cybersecurity and assesses their potential to strengthen defense mechanisms. Our review reveals that valuable AI tools are already in use for network protection and other cybersecurity areas through neural networks. However, some cybersecurity challenges can only be effectively addressed by employing AI strategies. For example, comprehensive data is essential for strategic decision-making, and the need for logical decision support remains a critical unresolved issue in cybersecurity.

description: In this research, we present an innovative, parameter-efficient model that utilizes the attention U-Net architecture for the automatic detection and eradication of non-speech vocal sounds, specifically breath sounds, in vocal recordings. This task is of paramount importance in the field of sound engineering, despite being relatively under-explored. The conventional manual process for detecting and eliminating these sounds requires significant expertise and is extremely time-intensive. Existing automated detection and removal methods often fall short in terms of efficiency and precision. Our proposed model addresses these limitations by offering a streamlined process and superior accuracy, achieved through the application of advanced deep learning techniques. A unique dataset, derived from Device and Produced Speech (DAPS), was employed for this purpose. The training phase of the model emphasizes a log spectrogram and integrates an early stopping mechanism to prevent overfitting. Our model not only conserves precious time for sound engineers but also enhances the quality and consistency of audio production. This constitutes a significant breakthrough, as evidenced by its comparative efficiency, necessitating only 1.9M parameters and a training duration of 3.2 hours - markedly less than the top-performing models in this domain. The model is capable of generating identical outputs as previous models with drastically improved precision, making it an optimal choice.

description: 5-Chloro-2-hydroxybenzophenone-S-methyl-4-phenylthiosemicarbazone (Η2L1) was synthesized from 4-phenylthiosemicarbazide. Reaction of Η2L1 with [bis(acetylacetonato)dioxomolybdenum(VI)] gave the dioxomolybdenum(VI) complexes with [MoO2(L1)(L2)] composition where L2 is n-pentanol, ethylene glycol monomethyl ether, ethyl acetate, isoamyl alcohol, pyridine, or γ-picoline. The structures of the stable solid complexes were elucidated using elemental analysis, electronic, FTIR, and 1H NMR spectra. Crystallographic analysis of [MoO2(L1)(n-pentanol)] (1) clearly indicated the O,N,N-chelating thiosemicarbazone backbone and the distorted octahedral environment of the molybdenum atom. Complex 1 crystallizes in the monoclinic system with P21/n space group and Z = 4. Moreover, the quantum chemical calculations supporting the experimental data of 1–6 are also reported in this study. Geometric optimization and theoretical vibrational spectra calculations of the complexes were performed by using the B3LYP density functional level of theory with LANL2DZ basis set employing density functional theory (DFT). Also, the non-covalent interaction (NCI) plot index analysis reveals the presence of different kinds of non-covalent interactions in [MoO2(L1)(n-pentanol)] (1).

description: Spacetime foam, also known as quantum foam, has its origin in quantum fluctuations of spacetime. Arguably it is the source of the holographic principle, which severely limits how densely information can be packed in space. Its physics is also intimately linked to that of black holes and computation. In particular, the same underlying physics is shown to govern the computational power of black hole quantum computers.

description: In the current work, a symmetrical tetradentate Schiff base ligand (H2L) derived by the condensation of methoxy-salicylaldehyde with substituted phenylenediamine is used to prepare nickel (II) and palladium (II) complexes. The chemical structures of the synthesized compounds were investigated with the help of combustion analysis and spectrophotometrically using FT-IR and 1H NMR. H2L and its nickel (II) complex were obtained in pure crystalline form, and hence, these compounds were characterized by diffraction analysis. It was evident from single-crystal X-ray diffraction analysis (SC-XRD) that the ligand was doubly deprotonated (L−2) and coordinated with the Ni(II) ion via ONNO-donor sites, and a distorted square planar geometry was achieved. Interestingly, the complex also attaches a solvent molecule (DMF) through its electronegative O atom with the H atom of DMF through hydrogen bonding. The molecular structure of the synthesized compounds was further validated with the help of density functional theory (DFT) using the B3LYP/Def2-TZVP level of theory. Furthermore, the Pd(II) complex was tested for Suzuki–Miyaura cross-coupling reactions and the results showed better catalytic activity in mild conditions concerning the traditionally available catalysts.

AN APPLICATION OF NEUTRIX CALCULUS TO QUANTUM FIELD THEORY
Creators: name: NG, Y. JACK
name: VAN DAM, H.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: Neutrices are additive groups of negligible functions that do not contain any constants except 0. Their calculus was developed by van der Corput and Hadamard in connection with asymptotic series and divergent integrals. We apply neutrix calculus to quantum field theory, obtaining finite renormalizations in the loop calculations. For renormalizable quantum field theories, we recover all the usual physically observable results. One possible advantage of the neutrix framework is that effective field theories can be accommodated. Quantum gravity theories appear to be more manageable.

description: Two new Sm(III) complexes, [Sm(L1)2Cl(H2O)]·3H2O and [Sm(L2)2Cl(H2O)]·2H2O, where HL1 is (E)-4-bromo-2-(((4-(2-hydroxyethyl)phenyl)imino)methyl)phenol and HL2 is (E)-2-(((4-(2-hydroxyethyl)phenyl)imino)methyl)-4-methoxyphenol, are reported. From the spectral data, it was deduced that the two Schiff base ligands existed as monobasic bidentate ON bonded to samarium(III) through deprotonated hydroxyl oxygen and azomethine nitrogen adopting an octahedral environment around Sm(III). The optimized structures, molecular electrostatic potential, and the energies HOMO and LUMO were calculated using DFT/B3LYP calculations employing the Gaussian 09 program. The antimicrobial efficacy of complexes and their parent ligands have been tested in vitro against various strains of bacteria and fungus. The antimicrobial activity of the new complexes has been enhanced compared to their parent free ligands. MTT assay was used to assess the in vitro cytotoxicity of the ligands and their Sm(III) complexes against the human breast cancer cell line (MCF-7) and human liver carcinoma cell line (Hep-G2). The CT-DNA binding constants of the interaction have been calculated and follow the order SmL1 > SmL2.

description: Image steganography is a technique to conceal secret messages within digital images. Steganalysis, on the contrary, aims to detect the presence of secret messages within images. Recently, deep-learning-based steganalysis methods have achieved excellent detection performance. As a countermeasure, adversarial steganography has garnered considerable attention due to its ability to effectively deceive deep-learning-based steganalysis. However, steganalysts often employ unknown steganalytic models for detection. Therefore, the ability of adversarial steganography to deceive non-target steganalytic models, known as transferability, becomes especially important. Nevertheless, existing adversarial steganographic methods do not consider how to enhance transferability. To address this issue, we propose a novel adversarial steganographic scheme named Natias. Specifically, we first attribute the output of a steganalytic model to each neuron in the target middle layer to identify critical features. Next, we corrupt these critical features that may be adopted by diverse steganalytic models. Consequently, it can promote the transferability of adversarial steganography. Our proposed method can be seamlessly integrated with existing adversarial steganography frameworks. Thorough experimental analyses affirm that our proposed technique possesses improved transferability when contrasted with former approaches, and it attains heightened security in retraining scenarios.

description: We investigate finite-size scaling of genuine multisite entanglement in the ground state of quantum spin-1/2 Heisenberg ladders. We obtain the ground states of odd- and even-legged Heisenberg ladder Hamiltonians and compute genuine multisite entanglement, the generalized geometric measure (GGM), which shows that for even rungs, GGM increases for odd-legged ladder while it decreases for even ones. Interestingly, the ground state obtained by short-range dimer coverings, under the resonating valence bond (RVB) ansatz, encapsulates the qualitative features of GGM for both the ladders. We find that while the GGMs for higher legged odd- and even-ladders converge to a single value in the asymptotic limit of a large number of rungs, the finite-size scaling exponents of the same tend to diverge. The scaling exponent of GGM obtained by employing density matrix recursion method is therefore a reliable quantity in distinguishing the odd-even dichotomy in Heisenberg ladders, even when the corresponding multisite entanglements merge.

Home Sweet Home? Investigating Users’ Awareness of Smart Home Privacy Threats

description: Albeit providing many benefits, smart homes collect and process large amounts of sensitive data. In order to successfully cope with the resulting risks for their privacy, users have to be aware of potential privacy threats and consequences in the first place. Since research in other contexts has shown that users often lack this awareness even when it comes to well-known technologies, e.g., Online Social Networks (OSN), it is crucial to investigate users' awareness of threats related to the use of unfamiliar technologies like smart homes. To this end, we conducted a survey study with 1052 lay users. By prompting participants to state all consequences that could potentially result from using smart home and smart health devices as well as OSN, we find that most participants were unable to state a single privacy consequence. Instead, most referred to general privacy issues (e.g., profiling, data collection) or threats related to non-privacy topics, such as security problems resulting from defect smart home devices. Since our participants were least aware of potential privacy consequences resulting from the use of smart home devices, further effort is necessary to inform lay users about possible privacy threats, e.g., by launching public campaigns or conducting trainings and interventions directly implemented in the UIs of smart home systems.

ENTROPIC INFLATION

description: One of the major pillars of modern cosmology theory is a period of accelerating expansion in the early universe. This accelerating expansion, or inflation, must be sustained for at least 30 e–foldings. One mechanism used to drive the acceleration is the addition of a new energy field, called the Inflaton; often this is a scalar field. We propose an alternative mechanism which, like our approach to explain the late-time accelerating universe, uses the entropy and temperature intrinsic to information holographically stored on a surface enclosing the observed space. The acceleration is due in both cases to an emergent entropic force, naturally arising from the information storage on the horizon.

description: This study investigates the design, development, and evaluation of a Large Language Model (LLM)-based chatbot for teaching English conversations in an English as a Foreign Language (EFL) context. Employing the Design and Development Research (DDR), we analyzed needs, established design principles, and iteratively refined a chatbot through experimenting various LLMs and alignment methods. Through both quantitative and qualitative evaluations, we identified the most effective LLM and its prompt combination to generate high-quality, contextually appropriate responses. Interviews with teachers provided insights into desirable system features, potential educational applications, and ethical considerations in the development and deployment of the chatbots. The design iterations yielded the importance of feedback mechanisms and customizable AI personas. Future research should explore adaptive feedback strategies, collaborative approaches with various stakeholders, and the integration of insights from human-computer interaction (HCI) and user experience (UX) design. This study contributes to the growing body of research on applying LLMs in language education, providing insights and recommendations for the design, development, and evaluation of LLM-based chatbots for EFL conversation practice. As the field evolves, ongoing research and collaboration among educators, AI engineers, and other stakeholders will be essential to harness the potential of these technologies to enhance language learning experiences.

GUTZWILLER APPROXIMATION IN DEGENERATE HUBBARD MODELS
Creators: name: Lu, Jian Ping
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1996

description: Degenerate Hubbard models are studied using the Generalized-Gutzwiller-Approximation. It is found that the metal-insulator transition occurs at a finite correlation Uc when the average number of electrons per lattice site is an integer. The critical Uc depends sensitively on both the band degeneracy N and the filling x. A derivation is presented for the general expression of Uc(x,N) which reproduces all previously known Gutzwiller solutions, including that of the Boson Hubbard model. Effects of the lattice structure on the metal-insulator transition and the effective mass are discussed.
