description: We derive the asymptotic winding law of a Brownian particle in the plane subjected to a tangential drift due to a point vortex. For winding around a point, the normalized winding angle converges to an inverse Gamma distribution. For winding around a disk, the angle converges to a distribution given by an elliptic theta function. For winding in an annulus, the winding angle is asymptotically Gaussian with a linear drift term. We validate our results with numerical simulations.

description: The $pp\to ppγ$ bremsstrahlung cross section is calculated within the method of coordinate space representation. It is shown that in the beam energy range of 350--450~MeV a deep attractive NN-potential with forbidden states (Moscow potential) and realistic meson exchange potentials (MEP) give rise to the cross sections that differ essentially in shape: the cross sections nearly coincide in the minima but differ by a factor of 5 approximately in the maxima. Therefore, the $pp\to ppγ$ reaction at energies $\sim$350--450~Mev can be used to study $NN$ interaction off-shell and to discriminate experimentally between MEP and Moscow potential.

description: In the course of the present thesis, the first method for the spatially resolved surface immobilization of various metallopolymers on a single surface was developed, employing the versatile NITEC photochemistry. The in-depth analysis of the photoligation process identified crucial parameters for the successful immobilization of the metallopolymers, which are also valid for all other photo triggered surface ligation protocols. ToF-SIMS and spatially resolved XPS analysis of the prepared surfaces demonstrated the preserved chemical composition of the fabricated metallopolymer surfaces. In the second part of the thesis, the photochemistry of spiro(thio)pyrans was investigated for the formation of light-sensitive spiropyran-metal complexes, as well as the creation of a photoresist for the application in STED-inspired lithography. The irradiation of an NMR tube inside the NMR spectrometer in so-called LED-NMR experiments was introduced for the investigation of the prepared spiropyran-metal complexes. Finally, the photo triggered reaction of the spirothiopyran photoswitch with an electron deficient maleimide was used for the spatial encoding of surfaces for the first time. In addition, the preparation of a spirothiopyran-based photoresist enabled the writing of structures below the diffraction limit, with the thinnest lines written with STED-inspired lithography to date.
title: Changes in Caloric Content as a Result of Sub-Lethal Stress in Neanthes Virens (SARS)

description: Neanthes virens were subjected to a toxicity test with 1.8, 3.4, 6.7 and 11.0 mg/1 Cd2+. Worms were withdrawn on Days 1, 4, 7, 10 and 14 from each of five replicate tanks and their caloric content determined by bomb calorimetry. Analyses of variance and covariance showed no significant differences in worm caloric content with withdrawal day or cadmium concentration.

In a second experimental series, a sediment toxicity test with Neanthes virens was conducted in contaminated sediments from two sites, as well as reference sediments from a control site. Caloric content of the worms was measured by bomb calorimetry at Day 14. The results indicated no difference between the caloric contents of the worms exposed to sediments from the three sites. The paper presents various methods of sublethal stress measurement and suggests reasons for lack of significant results.

description: Two undescribed benzofuran derivatives (1-2) were isolated from Chaetomium elatum using silica gel, Sephadex LH-20 column chromatography, and preparative high-performance liquid chromatography (HPLC). The structures of compound 1-2 were characterised by HRESIMS, NMR, HMBC, NOESY spectral analyses, and ECD calculations. Compounds 1-2 demonstrated the ability to mitigate the inflammatory response triggered by lipopolysaccharide (LPS) in RAW264.7 macrophages, as evidenced by RT-PCR assay results showing suppression of key inflammatory factors at the concentration of 30 μM. These findings suggest that 1-2 possess promising anti-inflammatory properties.

description: Cosmic microwave background measurements show an agreement with the concordance cosmology model except for a few notable anomalies: Power Suppression, the lack of large scale power in the temperature data compared to what is expected in the concordance model, and Cosmic Hemispherical Asymmetry, a dipolar breakdown of statistical isotropy. An expansion of the CMB covariance in Bipolar Spherical Harmonics naturally parametrizes both these large-scale anomalies, allowing us to perform an exhaustive, fully Bayesian joint analysis of the power spectrum and violations of statistical isotropy up to the dipole level. Our analysis sheds light on the scale dependence of the Cosmic Hemispherical Asymmetry. Assuming a scale-dependent dipole modulation model with a two-parameter power law form, we explore the posterior pdf of amplitude $A(l = 16)$ and the power law index $α$ and find the maximum a posteriori values $A_*(l = 16) = 0.064 \pm 0.022$ and $α_* = -0.92 \pm 0.22$. The maximum a posteriori direction associated with the Cosmic Hemispherical Asymmetry is $(l,b) = (247.8^o, -19.6^o)$ in Galactic coordinates, consistent with previous analyses. We evaluate the Bayes factor $B_{SI-DM}$ to compare the Cosmic Hemispherical Asymmetry model with the isotropic model. The data prefer but do not substantially favor the anisotropic model ($B_{SI-DM}=0.4$). We consider several priors and find that this evidence ratio is robust to prior choice. The large-scale power suppression does not soften when jointly inferring both the isotropic power spectrum and the parameters of the asymmetric model, indicating no evidence that these anomalies are coupled.

description: Constructing digital models of firefighting assets is essential for informed decision-making in emergency response and management. However, current practices struggle to efficiently recognize and update these assets in building information models (BIM). This study proposes a framework integrating photogrammetric reconstruction and instance segmentation to enrich BIM. The framework involves creating an expanded firefighting asset dataset and leveraging panoramic images with supervised learning for scene reconstruction and asset segmentation. Real-world evaluation illustrates it performs satisfactorily in both asset recognition and positioning. The framework offers a practical solution for modeling digital twins to support various fire emergency applications.
Interplay of spin and orbital ordering in the layered colossal magnetoresistance manganite La2-2xSr1+2xMn2O7 (0.5<=x<=1.0)

description: The crystallographic and magnetic phase diagram of the n=2 layered manganite La2-2xSr1+2xMn2O7 in the region x=>0.5 has been studied using temperature dependent neutron powder diffraction. The magnetic phase diagram reveals a progression of ordered magnetic structures generally paralleling that of 3-D perovskites with similar electronic doping: A (0.5<=x<=0.66) --> C (0.75<=x<=0.90) --> G (0.90<=x<=1.0). However, the quasi-2-D structure amplifies this progression to expose features of manganite physics uniquely accessible in the layered systems: (a) a "frustrated" region between the A and C regimes where no long-range magnetic order is observed; (b) magnetic polytypism arising from weak inter-bilayer magnetic exchange in the Type-C regime; and (c) a tetragonal to orthorhombic phase transition whose temperature evolution directly measures ordering of d3y2-r2 orbitals in the a-b plane. This orbital-ordering transition is precursory to Type-C magnetic ordering, where ferromagnetic rods lie parallel to the b-axis. These observations support the notion that eg orbital polarisation is the driving force behind magnetic spin ordering. Finally, in the crossover region between Type-C and Type-G states, we see some evidence for the development of local Type-C clusters embedded in a Type-G framework, directly addressing proposals of similar short-range magnetic ordering in highly-doped La1-xCaxMnO3 perovskites.

description: We argue on the basis of symmetry selection rules and Raman scattering spectra that NaV$_2$O$_5$ undergoes a charge ordering phase transition at T$_c$=34 K. Such a transition is characterized by the redistribution of the charges at the phase transition and corresponds to the change of the vanadium ions, from uniform V$^{4.5+}$ to two different V$^{4+}$ and V$^{5+}$ states. In the low temperature phase the V$^{4+}$ ions are forming a "zig-zag" ladder structure along the {\bf b}-axis, consistent with the symmetry of the P2/b space group.

description: The aim of the present study is to investigate the linkages between local economic development, innovation, and environmental sustainability inside urban areas. Can innovation affect the improvement of the quality of life inside urban areas? This research question comes from the consideration that usually innovation and growth in general are considered sources of conflict in affecting the livability of large cities. The objective of the paper is to design a model — the “SustaIn-Led” - to connect levels of environmental sustain-ability, quality of life, and economic development inside metropolitan areas, taking into account also innovationprocesses, activated by the innovation policies and by the knowledge economy. The study takes in consideration the 53 largest United States metropolitan areas with a population over 1 million, with a time series from the years 2000 through 2015.This has been done because of a two-fold reason: (1) the US among high-income countries is the one with the highest number of universities, patents, and citations; (2) several studies have shown that innovation occurs in large cities. The first part of the present study has carried out the identification of the variables to represent and significantly explain the phenomena – local economic development, innovation, and environmental sustainability – linked to the design of the SustaIn-LED model. Environmental sustainability in urban areas in this paper is represented by means of the Air Quality Index (AQI),while the number of workers synthetically quantifies local economic development. Correlation and multiple regression analyses are conducted in order to examine the relationship between the three main indicators. The multiple regressions for the year 2015 produced a low p-value, indicating that the predictors are significant in the regression analysis. Similar results of p-value are shown in all the years from 2000 to 2013. For 2015, the results showed that part of the variance in the measure of total workers of the metropolitan areas could be predicted by measures of innovation and air quality. Higher R2values have been registered for the years from 2000 through2013.The development of the SustaIn-LED model could be utilized in urban regeneration processes to help in the de-sign of new urban planning policies inside large cities by means of a better comprehension of environmental and economic implications caused by the implementation of innovation policies.

For some probability distribution of the interactions the ground state energy is calculated analytically within the replica symmetry assumptionand is found to be saturated by a cluster algorithm.

Jackiw-Rebbi zero modes in non-uniform topological insulator nanowire

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We theoretically investigate the emergence of Jackiw-Rebbi zero modes and their conductance signature in non-uniform topological insulator nano-wires. We modelled the non-uniform nano-wires as junction between two cylindrical nano-wires with different radius. In the limit of wire length being much larger than its radius, the surface state of the nanowire splits into one dimensional Dirac modes propagating along the axis of the cylinder owing to radial confinement. The sign of the mass gap in each of these Dirac mode is decided by angular momentum quantum number corresponding to the rotational motion of the electron about the axis of the cylindrical. Application of an external magnetic flux through the cylindrical nanowires enables us to tune the mass gap from positive to negative value across the junction. Due to this flux tunable band inversion, controlled by the external magnetic filed, Jackiw-Rebbi zero modes can be made to appear or disappear at the junction. We compute differential conductance of our topological insulator nanowire junction and show that a quantized conductance peak appears at zero-energy (zero-bias) in the presence of the Jackiw-Rebbi mode.

description: 1. The mass balance, pharmacokinetics and metabolism of rovatirelin were characterised in healthy male subjects after a single oral dose of [14C]rovatirelin. [14C]Rovatirelin was steadily absorbed, and the peak concentrations of radioactivity and rovatirelin were observed in plasma at 5–6 h after administration. The AUCinf of radioactivity was 4.9-fold greater than that of rovatirelin. Rovatirelin and its metabolite (thiazoylalanyl)methylpyrrolidine (TAMP) circulated in plasma as the major components. The total radioactivity recovered in urine and faeces was 89.0% of the administered dose. The principal route of elimination was excretion into faeces (50.1% of the dose), and urinary excretion was the secondary route (36.8%). Rovatirelin was extensively metabolised to 20 metabolites, and TAMP was identified as the major metabolite in plasma and excreta among its metabolites. 2. To identify the metabolic enzymes responsible for TAMP formation, the in vitro activity was determined in human liver microsomes. The enzymatic activity depended on NADPH, and it was inhibited by ketoconazole. Furthermore, recombinant human cytochrome P450 (CYP) 3A4 and CYP3A5 displayed enzymatic activity in the assay. Therefore, CYP3A4/5 are the most important enzymes responsible for TAMP formation.

description: Many-body systems with chiral fermions exhibit anomalous transport phenomena originated from quantum anomalies. Based on quantum field theory, we derive the kinetic theory for chiral fermions interacting with an external electromagnetic field and a background curved geometry. The resultant framework respects the covariance under the U(1) gauge, local Lorentz, and diffeomorphic transformations. It is particularly useful to study the gravitational or non-inertial effects for chiral systems. As the first application, we study the chiral dynamics in a rotating coordinate and clarify the roles of the Coriolis force and spin-vorticity coupling in generating the chiral vortical effect (CVE). We also show that the CVE is an intrinsic phenomenon of a rotating chiral fluid, and thus independent of observer's frame.

Random-bond Ising model in two dimensions, the Nishimori line, and supersymmetry

description: We consider a classical random-bond Ising model (RBIM) with binary distribution of $\pm K$ bonds on the square lattice at finite temperature. In the phase diagram of this model there is the so-called Nishimori line which intersects the phase boundary at a multicritical point. It is known that the correlation functions obey many exact identities on this line. We use a supersymmetry method to treat the disorder. In this approach the transfer matrices of the model on the Nishimori line have an enhanced supersymmetry osp($2n+1|2n$), in contrast to the rest of the phase diagram, where the symmetry is osp($2n|2n$) (where $n$ is an arbitrary positive integer). An anisotropic limit of the model leads to a one-dimensional quantum Hamiltonian describing a chain of interacting superspins, which are irreducible representations of the osp($2n+1|2n$) superalgebra. By generalizing this superspin chain, we embed it into a wider class of models. These include other models that have been studied previously in one and two dimensions. We suggest that the multicritical behavior in two dimensions of a class of these generalized models (possibly not including the multicritical point in the RBIM itself) may be governed by a single fixed point, at which the supersymmetry is enhanced still further to osp($2n+2|2n$). This suggestion is supported by a calculation of the renormalization-group flows for the corresponding nonlinear sigma models at weak coupling.

On the giant enhancement of light in plasmonic or all-dielectric gratings comprising nano-voids

description: We report the possibility to generate tremendous light-field enhancements within shallow nano-trenches made in a high index dielectric material, because of resonant behaviours reminiscent of what we get with sub-wavelength plasmonic cavities. The high quality factors are explained through a modal analysis and can be tuned with appropriate design rules. The thin dielectric void gratings here simulated could be a relevant alternative to plasmon-based devices for chemical sensing, or could be used as efficient wavelength-selective photo-absorbers by taking weakly absorbing materials.

description: Variations in the band structures of C60-polymers are studied, when conjugation conditions and the electron number are changed. We use a semiempirical model with the Su-Schrieffer-Heeger type electron-phonon interactions. In the neutral one-dimensional C60-polymer, electronic structures change among direct-gap insulators and the metal, depending on the degree of conjugations. High pressure experiments could observe such pressure-induced metal-insulator transitions. The C60-polymer doped with one electron per one molecule is always a metal. The energy difference between the highest-occupied state and the lowest-unoccupied state of the neutral system becomes smaller upon doping owing to the polaron effects. When the C60-polymer is doped with two electrons per one C60, the system is insulating. When the conjugation in the direction of the polymer chain is smaller, it is a direct-gap insulator. The energy gap becomes indirect when the conjugation is stronger. We also study the antiferromagnetic phase of AC60 by using a tight-binding model with long-range Coulomb interactions. The antiferromagnetism is well described by the model. The comparison with the photoemission studies shows that the new band around the Fermi energy of the AC60 phase can be explaind by the extremely large intrusion of an energy level into the gap of the neutral system. This indicates that the interaction effects among electrons are important in doped C60-polymers.

description: The global dairy sector is currently going through a period of turbulence. Global human population growth is substantially increasing the demand for dairy products. Our study stresses the importance of the dairy industry in the agriculture of the Ukraine and its national economy. It aims at identifying and describing the latest trends in the Ukrainian dairy industry. While the Ukrainian dairy sector is currently dealing with a number of challenges, we are looking for a number of opportunities for Ukrainian dairy producers to strengthen their competitiveness in the EU and global market, as well as maintain and expand their position on the domestic market. The dairy industry is one of the major industries in the Ukraine and, before the crisis, this segment demonstrated a trend towards its active development, but the situation in the dairy sector has become more complicated since 2014. The biggest problem for the dairy sector was the loss of the Russian market, which accounted for about 80% of exports of dairy products. However, the growth of cow productivity became a significant achievement of the dairy sector. Today, the main challenge for the dairy industry is finding new export markets and developing existing markets.

description: In this paper, we use a new hybrid method to compute the thermodynamic behavior of the spin-1/2 Kagome antiferromagnet under the influence of a large external magnetic field. We find a T^2 low-temperature behavior and a very low sensitivity of the specific heat to a strong external magnetic field. We display clear evidence that this low temperature magneto-thermal effect is associated to the existence of low-lying fluctuating singlets, but also that the whole picture (T^2 behavior of Cv and thermally activated spin susceptibility) implies contribution of both non magnetic and magnetic excitations. Comparison with experiments is made.

Chain length dependence of the polymer-solvent critical point parameters

description: We report grand canonical Monte Carlo simulations of the critical point properties of homopolymers within the Bond Fluctuation model. By employing Configurational Bias Monte Carlo methods, chain lengths of up to N=60 monomers could be studied. For each chain length investigated, the critical point parameters were determined by matching the ordering operator distribution function to its universal fixed-point Ising form. Histogram reweighting methods were employed to increase the efficiency of this procedure. The results indicate that the scaling of the critical temperature with chain length is relatively well described by Flory theory, i.e. Θ-T_c\sim N^{-0.5}. The critical volume fraction, on the other hand, was found to scale like ϕ_c\sim N^{-0.37}, in clear disagreement with the Flory theory prediction ϕ_c\sim N^{-0.5}, but in good agreement with experiment. Measurements of the chain length dependence of the end-to-end distance indicate that the chains are not collapsed at the critical point.

Absence of a metallic phase in random-bond Ising models in two dimensions: applications to disordered superconductors and paired quantum Hall states

description: When the two-dimensional random-bond Ising model is represented as a noninteracting fermion problem, it has the same symmetries as an ensemble of random matrices known as class D. A nonlinear sigma model analysis of the latter in two dimensions has previously led to the prediction of a metallic phase, in which the fermion eigenstates at zero energy are extended. In this paper we argue that such behavior cannot occur in the random-bond Ising model, by showing that the Ising spin correlations in the metallic phase violate the bound on such correlations that results from the reality of the Ising couplings. Some types of disorder in spinless or spin-polarized p-wave superconductors and paired fractional quantum Hall states allow a mapping onto an Ising model with real but correlated bonds, and hence a metallic phase is not possible there either. It is further argued that vortex disorder, which is generic in the fractional quantum Hall applications, destroys the ordered or weak-pairing phase, in which nonabelian statistics is obtained in the pure case.

description: We construct a lagrangian geometric formulation for first-order field theories using the canonical structures of first-order jet bundles, which are taken as the phase spaces of the systems in consideration. First of all, we construct all the geometric structures associated with a first-order jet bundle and, using them, we develop the lagrangian formalism, defining the canonical forms associated with a lagrangian density and the density of lagrangian energy, obtaining the {\sl Euler-Lagrange equations} in two equivalent ways: as the result of a variational problem and developing the {\sl jet field formalism} (which is a formulation more similar to the case of mechanical systems). A statement and proof of Noether's theorem is also given, using the latter formalism. Finally, some classical examples are briefly studied.

description: We study Seiberg duality for N=1 supersymmetric QCD with soft supersymmetry-breaking terms. We generate the soft terms through gauge mediation by coupling two theories related by Seiberg duality to the same supersymmetry-breaking sector. In this way, we know what a supersymmetry-breaking perturbation in one theory maps into in its ``dual''. Assuming a canonical Kahler potential we calculate the soft terms induced in the magnetic theory and find that some of the scalars acquire negative masses squared. If duality is still good for small supersymmetry breaking, this may imply some specific symmetry breaking patterns for supersymmetric QCD with small soft supersymmetry-breaking masses, in the case that its dual theory is weakly coupled in the infrared. In the limit of large supersymmetry breaking, the electric theory becomes ordinary QCD. However, the resulting symmetry breaking in the magnetic theory is incompatible with that expected for QCD.

description: Abstract

Background: Cancer is a leading global health concern, with early and precise detection playing a critical role in improving patient survival rates. Traditional diagnostic methods, while effective, often involve delays and human limitations. Recent advancements in artificial intelligence (AI) and machine learning have introduced new possibilities for enhancing diagnostic accuracy and efficiency, particularly through automated image analysis. Objective: This study aims to explore AI-driven techniques for cancer detection, focusing on deep learning models that analyze medical images to differentiate between malignant and benign tumors. The research evaluates various machine learning algorithms, assessing their accuracy, reliability, and potential for clinical application. Results: The findings demonstrate that AI-based diagnostic models can significantly improve the precision of cancer detection. Comparative analysis of multiple algorithms reveals that deep learning approaches, particularly convolutional neural networks (CNNs), achieve high accuracy in identifying cancerous lesions. The results suggest that AI integration in diagnostic processes can enhance early detection, reduce human error, and support medical professionals in making more informed decisions. This study reinforces the potential of AI-driven solutions in revolutionizing cancer diagnosis, paving the way for faster and more accurate detection, ultimately improving patient outcomes.

description: Bidentate ureido-dihomooxacalix[4]arene based supramolecular hosts (n-propyl 1 and tert-butyl 2) were processed into organic nanoparticles via a bottom up approach in which a single step of re-precipitation was employed. These organic nanoparticles were then coupled with gold nanoparticles on the surface, resulting in an organic – inorganic hybrid framework (n-propyl H1 and tert-butyl H2). Photophysical studies of the organic nanoparticles and of the hybrid material were performed. The size and morphology were determined by TEM and DLS analysis. Moreover, the prepared hybrid frameworks were screened against various anions using UV-Visible absorption and fluorescence spectrophotometry. H1 exhibited ratiometric response towards iodide ion in aqueous medium, and colour change of the solution from pink to light blue was observed. This hybrid material selectively and sensitively detected iodide ion with detection limit of 8.3 nM and with almost no interference from other anions. H1 sensor ability was also tested with artificial and real urine samples. H2 showed different responses and no selectivity to any anion.

description: We present an experimental scheme to measure the full distribution of many-body observables in spin systems, both in and out of equilibrium, using an auxiliary qubit as a probe. We focus on the determination of the magnetization and the kink-number statistics at thermal equilibrium. The corresponding characteristic functions are related to the analytically-continued partition function. Thus, both distributions can be directly extracted from experimental measurements of the coherence of a probe qubit that is coupled to an Ising-type bath, as reported in [X. Peng et al., Phys. Rev. Lett. 114, 010601 (2015)] for the detection of Lee-Yang zeroes.
