description: Interior Point Methods are widely used to solve Linear Programming problems. In this work, we present two primal affine scaling algorithms to achieve faster convergence in solving Linear Programming problems. In the first algorithm, we integrate Nesterov's restarting strategy in the primal affine scaling method with an extra parameter, which in turn generalizes the original primal affine scaling method. We provide the proof of convergence for the proposed generalized algorithm considering long step size. We also provide the proof of convergence for the primal and dual sequence without the degeneracy assumption. This convergence result generalizes the original convergence result for the affine scaling methods and it gives us hints about the existence of a new family of methods. Then, we introduce a second algorithm to accelerate the convergence rate of the generalized algorithm by integrating a non-linear series transformation technique. Our numerical results show that the proposed algorithms outperform the original primal affine scaling method.

description: We introduce a technique for testing the semiclassical limit of a quantum gravity vertex amplitude. The technique is based on the propagation of a semiclassical wave packet. We apply this technique to the newly introduced "flipped" vertex in loop quantum gravity, in order to test the intertwiner dependence of the vertex. Under some drastic simplifications, we find very preliminary, but surprisingly good numerical evidence for the correct classical limit.

description: The N-queens problem is to find the position of N queens on an N by N chess board such that no queens attack each other. The excluded diagonals N-queens problem is a variation where queens cannot be placed on some predefined fields along diagonals. This variation is proven NP-complete and the parameter regime to generate hard instances that are intractable with current classical algorithms is known. We propose a special purpose quantum simulator that implements the excluded diagonals N-queens completion problem using atoms in an optical lattice and cavity-mediated long-range interactions. Our implementation has no overhead from the embedding allowing to directly probe for a possible quantum advantage in near term devices for optimization problems.

description: V391 Peg (HS2201+2610) is an extreme horizontal branch subdwarf B (sdB) star, it is an hybrid pulsator showing p- and g-mode oscillations, and hosts a 3.2/sini M_Jup planet at an orbital distance of about 1.7 AU. In order to improve the characterization of the star, we measured the pulsation amplitudes in the u'g'r' SLOAN photometric bands using ULTRACAM at the William Herschel 4.2 m telescope and we compared them with theoretical values. The preliminary results presented in this article conclusively show that the two main pulsation periods at 349.5 and 354.1 s are a radial and a dipole mode respectively. This is the first time that the degree index of multiple modes has been uniquely identified for an sdB star as faint as V391 Peg (B=14.4), proving that multicolor photometry is definitely an efficient technique to constrain mode identification, provided that the data have a high enough quality.

description: Starting from a sample of SDSS quasars appearing also in the 2MASS survey, we study the continuum properties of about 1000 objects observed in 8 bands, from NIR to UV. We construct the mean spectral energy distribution (SED) and compare and contrast the continua of radio loud (RLQ) and radio quiet (RQQ) objects. The SEDs of the two populations are significantly different in the sense that RLQs are redder, with power law spectral indices =-0.55+/-0.04 and =-0.31+/-0.01 in the spectral range between 10^14.5 and 10^15.35 Hz. This difference is discussed in terms of different extinctions, different disc temperatures, or slopes of the non-thermal component.

description: Many parasites interfere with the behaviour of their hosts. In social animals, such as ants, parasitic interference can cause changes on the level of the individual and also on the level of the society. The ant-parasitic fungus Rickia wasmannii influences the behaviour of Myrmica ants by expanding the host’s nestmate recognition template, thereby increasing the chance of the colony accepting infected non-nestmates. Infected ants consistently show an increase of the alkane tricosane (n-C23) in their cuticular hydrocarbon profiles. Although experimental application of single compounds often elicits aggression towards manipulated ants, we hypothesized that the increase of n-C23 might underlie the facilitated acceptance of infected non-nestmates. To test this, we mimicked fungal infection in M. scabrinodis by applying synthetic n-C23 to fresh ant corpses and observed the reaction of infected and uninfected workers to control and manipulated corpses. Infected ants appeared to be more peaceful towards infected but not uninfected non-nestmates. Adding n-C23 to uninfected corpses resulted in reduced aggression in uninfected ants. This supports the hypothesis that n-C23 acts as a ‘pacifying’ signal. Our study indicates that parasitic interference with the nestmate discrimination of host ants might eventually change colony structure by increasing genetic heterogeneity in infected colonies.

description: Breast cancer continues to be the biggest cause of mortality for women worldwide, taking the lives of millions each year. As a result, scientists are now exploring the possibility of metal-based complexes as anticancer therapies. Notwithstanding, polypyridyl coordinated Re(I) complexes have demonstrated tremendous promise as cancer-fighting medications. Therefore, the intent of this research is to investigate theoretically the spectral properties, compute density functional theory (DFT), and simulate molecular docking of polypyridyl coordinated Re(I) complexes containing functionalized 2,2′-bipyridine N,N′-donor bidentate ligands: 5,5′-DiMBpy coordinated in (1a), 4,4′-DiMBpy coordinated in (2a), and 4,4′-DiMoxBp coordinated in (3a) for cancer therapy application. Intriguingly, the complex Re(2a) achieved the greatest MolDock score and H-bond energy following interactions with the target receptors utilized, followed by Re(1a) and Re(3), respectively. Thus elucidating the studied compounds to be efficient in the mitigation of breast cancer.

description: Interstellar H2S and its isotopic variant H2(S-34) have been observed toward several star-forming regions via their 1(10)-1(01) transitions at 2 mm, using the FCRAO telescope. In sources where both isotopic species were observed, column densities of about 10 to the 16th/sq cm were measured. Column density lower limits of about 10 to the 14th/sq cm for H2S were found for other sources, where only the main isotopic line was observed. The fractional abundances of H2S relative to molecular hydrogen appear to be enhanced by at least an order of magnitude relative to quiescent cloud values (about 10 to the -9th) for many of the observed sources.

Craving for drugs and food in daily life: an economic decision-making and computational modeling investigation
Creators: name: Grunevski, Sergej
Publisher: name: No Publisher Supplied
Year: 2025

description: Craving—the intense, specific desire for something—is a common part of our everyday experience. Most people report experiencing craving for chocolate and other palatable snacks. Craving (for drugs) is also a defining symptom of substance use disorders and predicts future drug use and relapse. In aiming to model the shared, defining features of food and drug craving in the laboratory, prior work has shown craving transforms subjective value for the object of craving (and similar choice options) in a multiplicative and time-bound fashion. Here, we investigated the generalizability of this laboratory signature of craving by simultaneously surveying different types of cravings and craving moments in participants’ daily lives. Treatment-engaged patients with opioid use disorder (OUD; N=67) and community control participants (N=49) took part in a 28- day experience sampling study. Each day, we asked participants to report on their momentary urge for opioids and food (sweet/savory), their immediate willingness-to-pay (subjective value) for opioids, a sweet, and a savory snack across different quantities, their current context, and past- hour exposure to drug use-associated cues. Consistent with our study goal, we captured participants’ data across a wide diversity of real-world contexts, and some of our OUD participants’ data in contexts known to provoke drug craving. Moments of drug urge were separable from sweet or savory urge moments in OUD participants, even though participants who desired opioids also tended to desire sweets. These urge moments predicted shifts in subjective value specific to the desired object: drug value by drug urge in OUD participants, and sweet value by sweet urge in both samples. Lastly, we used hidden Markov models to test whether craving moments can be reliably and formally captured under distinct craving “states” for each craving type, finding that our drug data could be well-characterized by a latent process where individuals transition between a “baseline” and a “drug craving” state marked by elevated drug urge and higher drug value. Our findings show that individuals experience craving-specific subjective value shifts in the real world where they can freely act on and be influenced by their environments. Combining this sampling design with computational modeling may provide a novel mechanism for treatment validation and allow us to infer a behavioral read-out of vulnerable moments that could be targeted with just-in-time interventions for behavior change.

description: We report the formation of new phases in bimetallic Au–Cu nanoparticles. These phases were observed in nanoparticle synthesised by adopting a three-step protocol in a single pot. Nanoparticles at 180°C for 1 h led to the formation of single-phase solid solution of Cu in Au. Subsequent heat treatment at 290°C for 2 h of these Au–Cu nanoparticles revealed three new phases. One of them relates to the modification of occupancy of Cu in an ordered AuCu tetragonal phase (tP4). This cell although retains tetragonal symmetry but displays metrical properties akin to that of a cube. The other two relates to vacancy ordering along <111> directions in the {111} planes of an ordered AuCu3 cubic phase (cP4). On the one hand, statistical occupancy of vacancy on Cu site in this cell leads to the reduction of cell size from ∼3.75 Å to ∼3.5 Å whereas ordering of vacant layer on the other hand gives rise to symmetry breaking. Former continues to display cubic symmetry whereas latter transforms to a trigonal cell.
A statistical analysis of the stochastic dynamics in financial and geomorphological systems using Artificial Intelligence and Probability Theory

description: This thesis is an investigation into the statistical properties of stochastic systems, primarily using financial data series and then applying the methods and analysis developed from the financial data to a geomorphological setting. This thesis starts by investigating the dynamics of the higher order statistical and standardised moments for financial time series when the time series are truncated to different lengths. We compare these dynamics to a Generalised Autoregressive Conditional Heteroskedasticity (GARCH) model, to elucidate the extent a GARCH model can be used to fit the empirical data within these time windows. When we seek to use a Gaussian conditional distribution to describe the distribution of price change, we cannot fit the empirical data using the higher order standardised moments of the time series. Nevertheless, when we instead use a double Gaussian conditional distribution, we are able to fit empirical data using the GARCH-double-normal model. However, with such a conditional distribution, the fitting becomes time dependent. The parameters of the distribution that can fit the time windows changes with the length of the time window. As a result, we are able to extract a signal of the 2008 banking crisis, and the 2020 global COVID-19 pandemic from the GARCH parameter's, α0, value for different financial securities. [...]

description: There is a general perception that large piezoelectric response in ferroelectric alloys requires tuning the system towards a morphotropic phase boundary (MPB), i.e., a composition driven inter-ferroelectric instability. Here we show that high piezoelectric response can be realized even in non-MPB alloy systems. This is demonstrated on (1-x)PbTiO3-(x)Bi(Zr0.5Ni0.5)O3 (PT-BNZ) by a comprehensive study involving electric-field and temperature dependent XRD, Raman spectroscopy, dielectric, piezoelectric and high field electrostrain measurements. We found that poling-field irreversibly suppresses the cubic-like phase at room temperature. Based on our results, we argue that that which appears as MPB, comprising of tetragonal and cubic-like phases on the global scale, is not so actually. The large piezoresponse is due to coexistence of tetragonal regions of long and short-range coherence. The PT-BNZ system is therefore qualitatively different from the conventional MPB systems such as PZT, PMN-PT, and PbTiO3-BiScO3, etc., which exhibits coexisting tetragonal and rhombohedral/monoclinic phases in thermodynamic equilibrium. In the absence of inter-ferroelectric instability as a phenomenon, field induced polarization-rotation and inter-ferroelectric transformation are no longer plausible mechanisms to explain the large piezoelectric response in PT-BNZ. The large piezoelectricity is primarily due to enhanced mobility of the tetragonal domain walls enabled by domain miniaturization. Our study proves that attainment of large piezoelectricity does not require inter-ferroelectric instability as a necessary criterion.

description: A series of heterocyclic derivatives (2a-2n) was synthesized and characterized by melting point, FT-IR 1H, 13C NMR, UV-visible spectroscopy and mass spectrometry. In vitro antifungal activity of the heterocyclic derivatives (2a-2n) was evaluated against the fungal strains: C. albicans, C. glabrata and C. tropicalis. The results revealed that heterocyclic analog 2a exhibits significant activity against all three strains with MIC value of 200 μg/mL, 2b exhibits antifungal activity against C. albicans with MIC value of 400 μg/mL and C. glabrata and C. tropicalis with MIC value of 500 μg/mL. Analog 2m also shows antifungal activity against C. albicans with MIC values of 200 μg/mL and C. glabrata and C. tropicalis with a MIC value 250 μg/mL as compared to the standard drug fluconazole. The binding interaction study of promising heterocyclic derivatives 2a, 2b, and 2m with CT-DNA was carried out by using UV-visible, fluorescence, cyclic voltammetry, circular dichroism, and viscosity measurements. The molecular docking study of the heterocyclic derivatives (2a–2n) was done with PDB ID: 1BNA. The pharmacokinetics properties of the heterocyclic derivatives (2a–2n) showed good oral bioavailability. Antioxidant potential of heterocyclic derivatives (2a–2n) was further approximated through DPPH and H2O2 free radical and showed that all the derivatives exhibited remarkable antioxidant activity.

description: We study the 37 brightest radio sources in the Subaru/XMM-Newton Deep Field (SXDF). Using mid-IR (Spitzer MIPS 24 micron) data we expect to trace nuclear accretion activity, even if it is obscured at optical wavelengths, unless the obscuring column is extreme. Our results suggest that above the `FRI/FRII' radio luminosity break most of the radio sources are associated with objects that have excess mid-IR emission, only some of which are broad-line objects, although there is one clear low-accretion-rate FRI. The fraction of objects with mid-IR excess drops dramatically below the FRI/FRII break, although there exists at least one high-accretion-rate QSO. Investigation of mid-IR and blue excesses shows that they are correlated as predicted by a model in which a torus of dust absorbs ~30% of the light, and the dust above and below the torus scatters >~1% of the light.

description: The dual concepts of coverings and packings are well studied in graph theory. Coverings of graphs with balls of radius one and packings of vertices with pairwise distances at least two are the well-known concepts of domination and independence, respectively. In 2001, Erwin introduced \emph{broadcast domination} in graphs, a covering problem using balls of various radii, where the cost of a ball is its radius. The minimum cost of a dominating broadcast in a graph $G$ is denoted by $γ_b(G)$. The dual (in the sense of linear programming) of broadcast domination is \emph{multipacking}: a multipacking is a set $P \subseteq V(G)$ such that for any vertex $v$ and any positive integer $r$, the ball of radius $r$ around $v$ contains at most $r$ vertices of $P$. The maximum size of a multipacking in a graph $G$ is denoted by $mp(G)$. Naturally, $mp(G) \leq γ_b(G)$. Hartnell and Mynhardt proved that $γ_b(G) \leq 3 mp(G) - 2$ (whenever $mp(G)\geq 2$). In this paper, we show that $γ_b(G) \leq 2mp(G) + 3$. Moreover, we conjecture that this can be improved to $γ_b(G) \leq 2mp(G)$ (which would be sharp).

description: Attribute-based naming enables powerful search and organization tools for ever-increasing user data sets. However, such tools are only useful in combination with accurate attribute assignment. Existing systems rely on user input and content analysis, but they have enjoyed minimal success. This paper discusses new approaches to automatically assigning attributes to files, including several forms of context analysis, which has been highly successful in the Google web search engine. With extensions like application hints (e.g., web links for down-loaded files) and inter-file relationships, it should be possible to infer useful attributes for many files, making attribute-based search tools more effective.

description: We discuss why regular observables can not be proper entanglement measures, and how observables in a generalized setting can be used to make an entanglement monotone a directly observable quantity for the case of pure states. For the case of mixed states, these generalized observables can be used to find valid lower bounds on entanglement monotones that can be measured in laboratory experiments in the same fashion as it can also be done for pure states.

To that end, a simple multichannel phase-noise model is considered and the maximum a posteriori detector for this model is approximated using two frameworks, namely factor graphs (FGs) combined with the sum-product algorithm (SPA), and a variational Bayesian (VB) inference method. The resulting pilot-aided algorithms perform iterative phase-noise compensation in cooperation with a decoder, using extended Kalman smoothing to estimate the a posteriori phase-noise distribution jointly for all channels. The system model and the proposed algorithms are verified using experimental data obtained from space-division multiplexed multicore-fiber transmission. Through Monte Carlo simulations, the algorithms are further evaluated in terms of phase-noise tolerance for coded transmission. It is observed that they significantly outperform the conventional approach to phase-noise compensation in the optical literature. Moreover, the FG/SPA framework performs similarly or better than the VB framework in terms of phase-noise tolerance of the resulting algorithms, for a slightly higher computational complexity.

description: Two C25 steroids with bicyclic [4.4.1] A/B rings were successfully separated from the marine fungus Aspergillus sp. LS116 by a two-step high-speed counter current chromatography (HSCCC). Petroleum ether/ethyl acetate/methanol/water (5.5:11:5:7, v/v) and petroleum ether/ethyl acetate/methanol/water (5:6:5:7, v/v) were selected as two optimum two-phase systems to purify two C25 steroids, neocyclocitrinol B (1) and threo-23-O-methylneocyclocitrinol (2). The purity of two compounds was over 94%. Their structures were determined by comprehensive spectroscopic techniques. This is the first report about rapid separation and identification of C25 steroids with bicyclic [4.4.1] A/B rings by HSCCC.

description: We provide a set of numerical N-body simulations for studying the formation of the outer Milky Ways's stellar halo through accretion events. After simulating minor mergers of prograde and retrograde orbiting satellite halo with a Dark Matter main halo, we analyze the signal left by satellite stars in the rotation velocity distribution. The aim is to explore the orbital conditions where a retrograde signal in the outer part of the halo can be obtained, in order to give a possible explanation of the observed rotational properties of the Milky Way stellar halo. Our results show that, for satellites more massive than $\sim 1/40$ of the main halo, the dynamical friction has a fundamental role in assembling the final velocity distributions resulting from different orbits and that retrograde satellites moving on low inclination orbits deposit more stars in the outer halo regions end therefore can produce the counter-rotating behavior observed in the outer Milky Way halo.

description: Higgs boson productions at the LHC will serve as a sensitive probe of various little Higgs models. In this work we comparatively study two littlest Higgs models with different T-parity constructions through examining their effects in three production processes of the Higgs boson at the LHC, namely the productions of a single Higgs, a Higgs-pair, as well as a Higgs boson associated with a pair of top and anti-top quarks. The two models are characterized by predicting a top partner canceling the Higgs mass quadratic divergence contributed by the top quark with even and odd T-parity, respectively. We find that both models can alter the SM cross sections sizably and their corrections also differ significantly. Therefore, the Higgs boson productions at the LHC may shed some light on these two models or even distinguish them.

description: Topological insulators are exotic material that possess conducting surface states protected by the topology of the system. They can be classified in terms of their properties under discrete symmetries and are characterized by topological invariants. The latter has been measured experimentally for several models in one, two and three dimensions in both condensed matter and quantum simulation platforms. The recent progress in quantum simulation opens the road to the simulation of higher dimensional Hamiltonians and in particular of the 4D quantum Hall effect. These systems are characterized by the second Chern number, a topological invariant that appears in the quantization of the transverse conductivity for the non-linear response to both external magnetic and electric fields. This quantity cannot always be computed analytically and there is therefore a need of an algorithm to compute it numerically. In this work, we propose an efficient algorithm to compute the second Chern number in 4D systems. We construct the algorithm with the help of lattice gauge theory and discuss the convergence to the continuous gauge theory. We benchmark the algorithm on several relevant models, including the 4D Dirac Hamiltonian and the 4D quantum Hall effect and verify numerically its rapid convergence.

description: Imidazole-based compounds form a prominent class of heterocyclic compounds, displaying diverse applications, especially with regards to its biological and pharmacological activities. Molecular docking, simulations, and drug-likeness prediction were performed on 45 imidazole-based alkaloids from two species of marine sponges (Leucetta and Clathrina). The study seeks to identify possible inhibitors of the SARS-CoV-2 Main Protease in an effort to battle the prevailing pandemic which has been caused by the widespread infections of the SAR-CoV-2 virus in its varied mutated forms. Computational analysis with MOE 2015.10 program reveals that, among the imidazole-based alkaloids, Naamidines have a high affinity for the target protein (PDB ID:6W63), even interacting with the catalytic dyad, as compared to its non-covalent inhibitor X77. Among all the top-scoring ligands, Naamidine H produced the highest binding score of −8.87078 kcal/mol. MD simulation studies with NAMD confirms the stability of the interactions of Naamidines with the target protein. MM-GBSA calculations were performed on the top binding ligands which further confirms the binding affinity of the top-scoring ligands. Computational and pharmacological investigations in this study proposes Naamidines, as effective inhibitors of Mpro. Naamidine I, Naamidine E, and Pyronaamidine could be potential anti-viral candidates against SAR-CoV-2.

description: We investigate a new identity for Green functions using the higher covariant derivative regularization. It relates some coefficients in the vertex function of the matter superfield, in which one of external matter lines is not chiral. The calculation in the first nontrivial order (for the two-loop vertex function) reveals that the new identity is also valid for the non-Abelian Yang--Mills theory with matter fields. The new identity is shown to appear because three-loop integrals, defining the Gell-Mann--Low function are factorized into integrals of total derivatives.

description: We present a new protocol to perform non-interactive verifiable secret redistribution (VSR) for secrets distributed with Shamir's secret sharing scheme. We base our VSR protocol on Desmedt and Jajodia's redistribution protocol for linear secret sharing schemes, which we specialize for Shamir's scheme. We extend their redistribution protocol with Feldman's non-interactive verifiable secret sharing scheme to ensure that a SUBSHARES-VALID condition is true after redistribution. We show that the SUBSHARES-VALID condition is necessary but not sufficient to guarantee that the new shareholders have valid shares, and present an additional SHARES-VALID condition.
Electroresistance effects in ferroelectric tunnel barriers

description: Electron transport through fully depleted ferroelectric tunnel barriers sandwiched between two metal electrodes and its dependence on ferroelectric polarization direction are investigated. The model assumes a polarization direction dependent ferroelectric barrier. The transport mechanisms, including direct tunneling, Fowler-Nordheim tunneling and thermionic injection, are considered in the calculation of the electroresistance as a function of ferroelectric barrier properties, given by the properties of the ferroelectric, the barrier thickness, and the metal properties, and in turn of the polarization direction. Large electroresistance is favored in thicker films for all three transport mechanisms but on the expense of current density. However, switching between two transport mechanisms, i.e., direct tunneling and Fowler-Nordheim tunneling, by polarization switching yields a large electroresistance. Furthermore, the most versatile playground in optimizing the device performance was found to be the electrode properties, especially screening length and band offset with the ferroelectric.

description: We study optimally doped Bi$_{2}$Sr$_{2}$Ca$_{0.92}$Y$_{0.08}$Cu$_{2}$O$_{8+δ}$ (Bi2212) using angle-resolved two-photon photoemission spectroscopy. Three spectral features are resolved near 1.5, 2.7, and 3.6 eV above the Fermi level. By tuning the photon energy, we determine that the 2.7-eV feature arises predominantly from unoccupied states. The 1.5- and 3.6-eV features reflect unoccupied states whose spectral intensities are strongly modulated by the corresponding occupied states. These unoccupied states are consistent with the prediction from a cluster perturbation theory based on the single-band Hubbard model. Through this comparison, a Coulomb interaction strength U of 2.7 eV is extracted. Our study complements equilibrium photoemission spectroscopy and provides a direct spectroscopic measurement of the unoccupied states in cuprates. The determined Coulomb U indicates that the charge-transfer gap of optimally doped Bi2212 is 1.1 eV.
