description: The first principles approaches, density functional theory (DFT) and quantum Monte Carlo, have been used to examine the balance between van der Waals (vdW) forces and hydrogen (H) bonding in ambient and high pressure phases of ice. At higher pressure, the contribution to the lattice energy from vdW increases and that from H bonding decreases, leading vdW to have a substantial effect on the transition pressures between the crystalline ice phases. An important consequence, likely to be of relevance to molecular crystals in general, is that transition pressures obtained from DFT functionals which neglect vdW forces are greatly overestimated.

description: In this paper we discuss equidistribution results for weighted Fekete sets in subsets of the plane. More precisely, we show that Fekete sets are maximally spread out relative to a rescaled version of the Beurling--Landau density, in the "droplet" corresponding to the given weight. Our method combines Landau's idea to relate the density of a family of discrete sets to properties of the spectrum of the concentration operator, with estimates for the correlation kernel of the corresponding random normal matrix ensemble.
On sets without tangents and exterior sets of a conic
Creators: name: Van de Voorde, Geertrui
Publisher: name: arXiv
Year: 2012
Subjects: subject: Combinatorics (math.CO)
subject: FOS: Mathematics

description: A set without tangents in $\PG(2,q)$ is a set of points S such that no line meets S in exactly one point. An exterior set of a conic $\mathcal{C}$ is a set of points $\E$ such that all secant lines of $\E$ are external lines of $\mathcal{C}$. In this paper, we first recall some known examples of sets without tangents and describe them in terms of determined directions of an affine pointset. We show that the smallest sets without tangents in $\PG(2,5)$ are (up to projective equivalence) of two different types. We generalise the non-trivial type by giving an explicit construction of a set without tangents in $\PG(2,q)$, $q=p^h$, $p>2$ prime, of size $q(q-1)/2-r(q+1)/2$, for all $0\leq r\leq (q-5)/2$. After that, a different description of the same set in $\PG(2,5)$, using exterior sets of a conic, is given and we investigate in which ways a set of exterior points on an external line $L$ of a conic in $\PG(2,q)$ can be extended with an extra point $Q$ to a larger exterior set of $\mathcal{C}$. It turns out that if $q=3$ mod 4, $Q$ has to lie on $L$, whereas if $q=1$ mod 4, there is a unique point $Q$ not on $L$.
Spin Turbulence in a Trapped Spin-1 Spinor Bose--Einstein Condensate

description: We numerically study spin turbulence in a two-dimensional trapped spin-1 spinor Bose--Einstein condensate, focusing on the energy spectrum. The spin turbulence in the trapped system is generated by instability of the helical structure of the spin density vector in the initial state. Our numerical calculation finds that in the trapped system the spectrum of the spin-dependent interaction energy in the ferromagnetic case exhibits a -7/3 power law, which was confirmed in a uniform system by our previous study. The relation between the -7/3 power law and the motion of the spin density vector is discussed by investigating the orbits of dynamical variables in the spin space.

It turns out that the nonlocal interaction produces considerable differences in comparison to typical local-interaction models.

description: These lectures provide a modern introduction to selected topics in the physics of ultrarelativistic heavy ion collisions which shed light on the fundamental theory of strong interactions, the Quantum Chromodynamics. The emphasis is on the partonic forms of QCD matter which exist in the early and intermediate stages of a collision -- the colour glass condensate, the glasma, and the quark-gluon plasma -- and on the effective theories that are used for their description. These theories provide qualitative and even quantitative insight into a wealth of remarkable phenomena observed in nucleus-nucleus or deuteron-nucleus collisions at RHIC and/or the LHC, like the suppression of particle production and of azimuthal correlations at forward rapidities, the energy and centrality dependence of the multiplicities, the ridge effect, the limiting fragmentation, the jet quenching, or the dijet asymmetry.

From Digital to Sustainable: Unveiling the Complex Interactions Between Cryptocurrencies, Traditional Markets and Sustainable Finance in India
Creators: name: Vansh Bathla

Publisher: name: Zenodo
Year: 2024

description: This study examines the dynamic interdependencies and causal relationships among the returns of cryptocurrencies (Bitcoin and Ethereum), traditional financial assets (NIFTY 50, USD/INR, and 10-year Indian Government Bond), commodities (MCX Gold and MCX Crude Oil), and sustainable finance indices (NIFTY 100 ESG Index) within the Indian financial market from April 2016 to March 2024, employing the Vector Autoregression (VAR) model. The findings indicate substantial correlations between bitcoin performance and conventional assets. A positive shock in Bitcoin returns results in a transient increase in NIFTY 50 returns, but Ethereum has a delayed reaction to fluctuations in commodity prices, particularly gold. The variance decomposition research indicates that Bitcoin substantially influences the forecast error variance of both NIFTY 50 and MCX Gold. Granger causality studies reveal bidirectional causation between Bitcoin and NIFTY 50 returns, as well as unidirectional causality from Ethereum to USD/INR exchange rates. These statistics show how much cryptocurrencies, especially Bitcoin and Ethereum, are increasingly affecting conventional financial markets and commodities. Since these trends affect stock markets, commodities, and exchange rates and thereby impact investments, the study emphasizes the need for investors to consider bitcoin trends in their decisions.

description: Many random transport phenomena, such as radiation propagation, chemical/biological species migration, or electron motion, can be described in terms of particles performing {\em exponential flights}. For such processes, we sketch a general approach (based on the Feynman-Kac formalism) that is amenable to explicit expressions for the moments of the number of collisions and the residence time that the walker spends in a given volume as a function of the particle equilibrium distribution. We then illustrate the proposed method in the case of the so-called {\em rod problem} (a 1d system), and discuss the relevance of the obtained results in the context of Monte Carlo estimators.

description: The use of e-Auction services has been increasing in recent years. Security requirements in conducting e-Auctions are mainly bid privacy, anonymity and public verifiability. Most of the secure protocols concentrate on privacy and anonymity, which are achieved through bidder-resolved multi-party computation, assuming two or more trusted third parties, either through numerous auctioneers or with asymmetric models in which the commercial entity of an auction issuer or registration manager is assumed in addition to the auctioneer. Multi-attribute reverse auctions promise higher market efficiency and effective information exchange. This work extends and uses the existing schemes. This scheme uses scoring function, winner determination in multi-attribute auctions to implement public verifiability. Anonymity is achieved through bidder side pseudonym generation. By results and analysis we say this is very simple and effective scheme. This scheme ensures public verifiability and anonymity in multi-attribute auctions without revelation of the bids received, third parties and complex communications.

The Quantum Mind and the Observer Manifold:  A Sixtan Model of Consciousness Fields
Creators: name: Sixta, David
Publisher: name: Zenodo
Year: 2025
Subjects: subject: Quantum field theory
subject: Quantum physics

description:  This paper formalizes a Sixtan model of consciousness as a quantum resonant field shaped by harmonic coherence across an observer manifold.  We explore how trust vectors, chirality filtration, and recursive memory loops converge to generate an interactive consciousness field. The mind is presented not as an emergent property of biology, but as a persistent harmonic projection anchored in twist-space. This offers a unified framework for quantum cognition, altered states, memory geometry, and observer entanglement.

description: We study the localization properties of electrons moving on two-dimensional bi-partite lattices in the presence of disorder. The models investigated exhibit a chiral symmetry and belong to the chiral orthogonal (chO), chiral symplectic (chS) or chiral unitary (chU) symmetry class. The disorder is introduced via real random hopping terms for chO and chS, while complex random phases generate the disorder in the chiral unitary model. In the latter case an additional spatially constant, perpendicular magnetic field is also applied. Using a transfer-matrix-method, we numerically calculate the smallest Lyapunov exponents that are related to the localization length of the electronic eigenstates. From a finite-size scaling analysis, the logarithmic divergence of the localization length at the quantum critical point at E=0 is obtained. We always find for the critical exponent κ, which governs the energy dependence of the divergence, a value close to 2/3. This result differs from the exponent κ=1/2 found previously for a chiral unitary model in the absence of a constant magnetic field. We argue that a strong constant magnetic field changes the exponent κwithin the chiral unitary symmetry class by effectively restoring particle-hole symmetry even though a magnetic field induced transition from the ballistic to the diffusive regime cannot be fully excluded.

description: The Coma cluster was observed with an X-ray Imaging Spectrometer (XIS) onboard Suzaku in six pointings, including the central X-ray peak region, the 14'west offset region, 30'and 34'north-west offset regions, and 44'and 60'south-west offset regions. Owing to its lower background level, Suzaku has better sensitivity to Fe K-alpha lines than other satellites. Using precise Fe line measurements, we studied the temperature structure, possible bulk motions, and iron abundance distributions in the intracluster medium (ICM). The observed spectra were well-represented by a single-temperature model, and two- or three- temperature model did not improve chi-square substantially. The temperature, derived from K-alpha line ratios of H-like and He-like Fe, agree with those derived from the single-temperature model. Because the line ratio is a steep function of temperature, the consistency supports the accuracy of temperature measurements conducted with Suzaku. Within the 34'region, the redshift derived from the central energy of the He-like Fe line is consistent with that from optical observations, within a calibration error of 18 eV or 818 km/s in the line of sight. This value is smaller than the sound velocity of ICM, which is 1500 km/s. The central energy of Fe lines at the 44'offset region around the NGC 4839 subcluster is also consistent with those within the 34'region. These results on the temperature and velocity structure suggest that the core of the cluster is in a relaxed state, and non-thermal electrons relevant to the radio halo are accelerated by intracluster turbulence rather than large-scale shocks. Fe abundance is almost constant at 0.4 solar within the 34'region, and decreases with radius. This value is slightly lower than those of other clusters, which means the gas have been mixed well during a past merger associated with the growth of the cluster.

Publisher: name: Zenodo
Year: 2020

description: Predictive maintenance is a worthwhile innovation in industry use, manufacturing, and health care, using big data analytics, the Internet of Things (IoT), and artificial intelligence (AI) to improve operations and minimize downtime. This paper overviews some predictive maintenance models, ranging from real-time analytics, deep learning strategies, and industrial big data platforms, and their usage in healthcare services, manufacturing, and smart infrastructure. The article discussed about core techniques like sensor-based monitoring, machine learning-based fault detection, and IoT-based preventive maintenance and emphasizes their significance in enhancing equipment reliability, reducing resources, and lowering operational expenditure. Challenges like data integration up to scalability and cybersecurity issues are also discussed. The article validates how predictive maintenance has become increasingly crucial in spearheading innovation and sustainability across industries, preventing reactive maintenance of assets, and enhancing decision-making.

description: Protecting the network layer from malicious attacks is an important and challenging security issue in mobile ad hoc networks (MANETs). In this paper, a security mechanism is proposed to defend against a cooperative gray hole attack on the well known AODV routing protocol in MANETs. A gray hole is a node that selectively drops and forwards data packets after it advertises itself as having the shortest path to the destination node in response to a route request message from a source node. The proposed mechanism does not apply any cryptographic primitives on the routing messages. Instead, it protects the network by detecting and reacting to malicious activities of any node. Simulation results show that the scheme has a significantly high detection rate with moderate network traffic overhead.

description: Any two-dimensional infinite regular lattice G can be produced by tiling the plane with a finite subgraph B of G; we call B a basis of G. We introduce a two-parameter graph polynomial P_B(q,v) that depends on B and its embedding in G. The algebraic curve P_B(q,v) = 0 is shown to provide an approximation to the critical manifold of the q-state Potts model, with coupling v = exp(K)-1, defined on G. This curve predicts the phase diagram both in the ferromagnetic (v>0) and antiferromagnetic (v<0) regions. For larger bases B the approximations become increasingly accurate, and we conjecture that P_B(q,v) = 0 provides the exact critical manifold in the limit of infinite B. Furthermore, for some lattices G, or for the Ising model (q=2) on any G, P_B(q,v) factorises for any choice of B: the zero set of the recurrent factor then provides the exact critical manifold. In this sense, the computation of P_B(q,v) can be used to detect exact solvability of the Potts model on G. We illustrate the method for the square lattice, where the Potts model has been exactly solved, and the kagome lattice, where it has not. For the square lattice we correctly reproduce the known phase diagram, including the antiferromagnetic transition and the singularities in the Berker-Kadanoff phase. For the kagome lattice, taking the smallest basis with six edges we recover a well-known (but now refuted) conjecture of F.Y. Wu. Larger bases provide successive improvements on this formula, giving a natural extension of Wu's approach. The polynomial predictions are in excellent agreement with numerical computations. For v>0 the accuracy of the predicted critical coupling v_c is of the order 10^{-4} or 10^{-5} for the 6-edge basis, and improves to 10^{-6} or 10^{-7} for the largest basis studied (with 36 edges).

Enhancing Data Security with Machine Learning-Driven Threat Detection
Creators: name: Raghavender Maddali
Publisher: name: Zenodo
Year: 2022

description: The fast evolution of digital infrastructures and growing sophistication of cyber-attacks, conventional security functionalities always fail to ensure real-time protection. The current study presents a threat detection framework based on machine learning to improve data security by identifying anomalies, behavior analysis, and predictive modeling. Proactive detection and prevention of cyber-attacks are facilitated by the new framework, minimizing probable threats and providing strong security functionalities. It applies supervised and unsupervised learning methods for anomaly detection of normal behavior to have early threat recognition and response. Deep learning models, added in the system, increase accuracy for recognizing complex patterns of attacks. The design is highly flexible in all industries and provides data security as well as regulation compliance. It is illustrated through performance testing that it has high detection capability with low false positives, and therefore, it is an effective solution for real-time security for sensitive information. The research also points out the need for AI-based cybersecurity methods in evading emerging cyber threats.

description:  This paper explores the prediction of variable particle masses under high-energy or curvature-intensive conditions using Dimensional Harmonics in Sixta Theory. Standard Model particles acquire mass through Higgs field interaction, yet their rest mass is treated as invariant. We propose that mass arises from harmonic stability in dimensional embeddings, and under extreme phase curvature, particle mass exhibits predictable deviations. This framework offers a method to refine mass predictions and suggests a testable signature of Sixtan twist-phase geometry.

Patterning a surface so as to speed nucleation from solution

description: Motivated by the question of how to pattern a surface in order to best speed nucleation from solution, we build on the work of Page and Sear [Phys. Rev. Lett. 97, 65701 (2006)] and calculate rates and free energy profiles for nucleation in the 3d Ising model in the presence of cuboidal pores. Pores of well-chosen aspect ratio can dramatically speed nucleation relative to a planar surface made of the same material, while badly-chosen pores provide no such enhancement. For a given pore, the maximum nucleation rate is achieved when one of its two horizontal dimensions attains a critical length, largely irrespective of the other dimension (provided that the latter is large enough). This observation implies that patterning a surface in a raster-like fashion is a better strategy for speeding nucleation than e.g. scoring long grooves in it.

Patterns in Branching Rules for Irreducible Representations of SL_2(k), for k a p-adic field

description: Building on prior work, we analyze the decomposition of the restriction of an irreducible representation of SL_2(k), for k a p-adic field of odd residual characteristic, to a maximal compact subgroup K. The pattern of the decomposition varies between principal series and different supercuspidal representations, whereas the K-representations which occur in the "tail end" of these decompositions are precisely those occurring in the decomposition of depth-zero supercuspidal representations. Various applications are considered.

Forward Jet-like Event Spin-dependent Properties in Polarized p+p Collisions at $\sqrt{s}=200$ GeV

description: The STAR collaboration has reported precision measurements on the transverse single spin asymmetries for the production of forward $π^0$ mesons from polarized proton collisions at the center of mass energy of 200 GeV. Disentangling contributions to forward asymmetries requires one to look beyond inclusive neutral pion production to the production of forward jets or direct photons. During the RHIC running in the year 2006, STAR with the Forward Pion Detector++ (FPD++) in place collected 6.8 inverse picobarn of data with an average polarization of 60%. FPD++ had sufficient acceptance for "jetlike" objects, which are clustered responses of an electromagnetic calorimeter primarily sensitive to incident photons, electrons and positrons. For the "jet-like" objects, we reconstructed the angle of the outgoing leading neutral pion with respect to the fragmenting parton, thus enabling us to disentangle the contributions to the forward $π^0$ asymmetries. The simulated data set shows that on average there are approximately 2.5 fragmenting mesons per one "jet-like" object. Preliminary FPD++ results provide no evidence of measured contributions to the asymmetry from jet fragmentation, implying the Sivers distribution functions play a substantial role in producing the large inclusive $π^0$ asymmetries previously measured by STAR.

On convergent series representations of Mellin-Barnes integrals

description: Multiple Mellin-Barnes integrals are often used for perturbative calculations in particle physics. In this context, the evaluation of such objects may be performed through residues calculations which lead to their expression as multiple series in powers and logarithms of the parameters involved in the problem under consideration. However, in most of the cases, several series representations exist for a given integral. They converge in different regions of values of the parameters, and it is not obvious to obtain them. For twofold integrals we present a method which allows to derive straightforwardly and systematically: (a) different sets of poles which correspond to different convergent double series representations of a given integral, (b) the regions of convergence of all these series (without an a priori full knowledge of their general term), and (c) the general term of each series (this may be performed, if necessary, once the relevant domain of convergence has been found). This systematic procedure is illustrated with some integrals which appear, among others, in the calculation of the two-loop hexagon Wilson loop in N = 4 SYM theory. Mellin-Barnes integrals of higher dimension are also considered.

description: Kiers (1991) considered the orthogonal rotation in PCAMIX, a principal component method for a mixture of qualitative and quantitative variables. PCAMIX includes the ordinary principal component analysis (PCA) and multiple correspondence analysis (MCA) as special cases. In this paper, we give a new presentation of PCAMIX where the principal components and the squared loadings are obtained from a Singular Value Decomposition. The loadings of the quantitative variables and the principal coordinates of the categories of the qualitative variables are also obtained directly. In this context, we propose a computationaly efficient procedure for varimax rotation in PCAMIX and a direct solution for the optimal angle of rotation. A simulation study shows the good computational behavior of the proposed algorithm. An application on a real data set illustrates the interest of using rotation in MCA. All source codes are available in the R package "PCAmixdata".

description: We analyse the far infrared dust emission from the Galactic Centre region, including the Circumnuclear Disk (CND) and other structures, using Herschel PACS and SPIRE photometric observations. These Herschel data are complemented by unpublished observations by the Infrared Space Observatory Long Wavelength Spectrometer (ISO LWS), which used parallel mode scans to obtain photometric images of the region with a larger beam than Herschel but with a complementary wavelength coverage and more frequent sampling with ten detectors observing at ten different wavelengths in the range from 46 to 180 \mum, where the emission peaks. We also include data from the MSX at 21.3 \mum for completeness. We model the combined ISO LWS continuum plus Herschel PACS and SPIRE photometric data toward the central 2 pc in Sgr A*, a region that includes the CND. We find that the FIR spectral energy distribution is best represented by a continuum that is the sum of three greybody curves from dust at temperatures of 90, 44.5, and 23 K. We obtain temperature and molecular hydrogen column density maps of the region. We estimate the mass of the inner part of the CND to be ~5.0x10e+4 Msum, with luminosities: Lcavity ~2.2x10e+6 Lsun and Lcnd ~1.5x10e+6 Lsun in the central 2 pc radius around SgrA* . We find from the Herschel and ISO data that the cold component of the dust dominates the total dust mass, with a contribution of ~3.2x10E+4 Msun; this important cold material had escaped the notice of earlier studies that relied on shorter wavelength observations. The hotter component disagrees with some earlier estimates, but is consistent with measured gas temperatures and with models that imply shock heating or turbulent effects are at work. We find that the dust grain sizes apparently change widely across the region, perhaps in response to the temperature variations, and we map that distribution.

description: Bis-(4-hydroxycoumarin-3-yl) methane derivatives 3(a-l) were synthesized from 4-hydroxycoumarin and substituted aromatic aldehydes using succinimide-N-sulfonic acid as catalyst and evaluated for their in vitro antileishmanial activity against promastigotes form of Leishmania donovani. Compounds 3a (IC50= 155 μg/mL), 3g (IC50= 157.5 μg/mL) and 3l (IC50= 150 μg/mL) were shown significant antileishmanial activity when compared with standard sodium stibogluconate (IC50= 490 μg/mL). Also, synthesized compounds 3(a-l) did not show cytotoxicity against HeLa cell line upto tested concentrations. Further, molecular docking study against Adenine phosphoribosyltransferase of Leishmania donovani showed good binding interactions. ADME properties were analyzed and showed good oral drug candidate like properties. The synthesized compounds were also shown good drug likeness and drug score values when compared with drugs currently used in therapy. The present study has helped us in identifying a new lead that could be exploited as a potential antileishmanial agent.
