description: Zinc alloys have emerged as promising candidates for biodegradable materials due to their remarkable biocompatibility and favorable mechanical characteristics. The incorporation of alloying elements plays an essential role in advancing the tensile strength of Zn alloys. Nevertheless, achieving uniform dispersion of these elements poses challenges due to chemical segregation during solidification. In this study, rapid solidification followed by high-pressure torsion was successfully employed to fabricate Zn-Li-Mn-Mg-Cu alloys characterized by ultrafine-grained microstructures with evenly distributed nanometric intermetallic phases. A comprehensive examination, including phase composition, microstructural evolution, tensile properties and deformation mechanisms, was conducted. The impact of varying annealing temperatures on microstructural stability was systematically examined. The combined implementation of rapid solidification and high-pressure torsion yielded alloys with an average grain size below 360 nm, thereby demonstrating exceptional mechanical properties including yield stress (YS), ultimate tensile strength (UTS), and elongation to failure (Ef) equal to at least 325+-6 MPa, 350+-8 MPa and 40+-11 %, respectively. Heat treatment notably augmented the mechanical properties, resulting in a YS = 440+-11 MPa and UTS = 491+-6 MPa, while preserving plasticity (Ef = 23+-4 %) in the Zn-0.33Li-0.27Mn-0.14Mg-0.1Cu alloy. Nanoindentation strain rate jump tests identified thermally activated mechanisms and grain boundary sliding as dominant deformation mechanisms.

description: Collisionless shocks are present everywhere in the universe, from the solar environment to distant supernovae. They are often associated with strong magnetic fields due to strong nonthermal radiation. However, it is still not well understood how magnetic fields are amplified at scales of the shock thickness. Here we use a set of large-scale Particle-In-Cell (PIC) simulations of non-relativistic perpendicular shocks in the high Mach number regime to clarify this issue. These shocks are Weibel-instability mediated. We present the evidence that the magnetic field is amplified in the shock transition due to the Weibel instability and the magnetic field strength strongly correlates with the Alfvénic Mach number. We propose a new explanation for this correlation. PIC simulation results can explain in-situ magnetic field measurements of Saturn's bow shock performed by the Cassini spacecraft.

description: Ultra-thin metallic anodic and cathodic wires are frequently employed in low-mass gaseous detectors for precision experiments, where the amount of material crossed by charged particles must be minimised. We present here the results of an analysis of the mechanical stress and chemical corrosion effects observed in $40$ and $50~{\rm{μm}}$ diameter silver plated aluminum wires mounted within the volume of the MEG\,II drift chamber, which caused the breaking of about one hundred wires (over a total of $\approx 12000$). This analysis is based on the accurate inspection of the broken wires by means of optical and electronic microscopes and on a detailed recording of all breaking accidents. We present a simple empirical model which relates the number of broken wires to their exposure time to atmospheric humidity and to their mechanical tension, which is necessary for mechanical stability in the presence of electrostatic fields of several kV/cm. Finally we discuss how wire breakings can be avoided or at least strongly reduced by operating in controlled atmosphere during the mounting stages of the wires within the drift chamber and by choosing a $25\,\%$ thicker wire diameter, which has very small effects on the detector resolution and efficiency and can be obtained by using a safer fabrication technique.

description: In this paper we set bounds on the radiation content of the Universe and neutrino properties by using the WMAP-5 year CMB measurements complemented with most of the existing CMB and LSS data (WMAP5+All),imposing also self-consistent BBN constraints on the primordial helium abundance. We consider lepton asymmetric cosmological models parametrized by the neutrino degeneracy parameter and the variation of the relativistic degrees of freedom, due to possible other physical processes occurred between BBN and structure formation epochs. We find that WMAP5+All data provides strong bounds on helium mass fraction and neutrino degeneracy parameter that rivals the similar bounds obtained from the conservative analysis of the present data on helium abundance. We also find a strong correlation between the matter energy density and the redshift of matter-radiation equality, z_re, showing that we observe non-zero equivalent number of relativistic neutrinos mainly via the change of the of z_re, rather than via neutrino anisotropic stress claimed by the WMAP team. We forecast that the CMB temperature and polarization measurements observed with high angular resolutions and sensitivities by the future Planck satellite will reduce the errors on these parameters down to values fully consistent with the BBN bounds.

description: This report contributes to enabling post-project commercialisation of the SteamBio superheated steam (SHS) technology in Southern Africa. It aims to describe fundamental functions of biomass supply chains that are relevant to the project context, and to introduce analytical methods to evaluate design alternatives for the supply chain of SHS plants. The fundamental functions are:

Harvesting systems and aftercare operations

Biomass comminution (processing)

Biomass transport

Storage and quality control

Use of terminals 

The report identifies opportunities to advance currently implemented biomass supply systems and practices in Southern Africa based on knowledge from developments in the Nordic forestry and bioenergy sectors. This includes recommendations and guidelines for when to use certain harvesting machines or truck configurations, or important considerations for long and short-term storage of biomass. Moreover, simulation-based methods for supply chain design are introduced, and a schematic illustration of a simulation model of the supply chain of SHS plants is given. As a further outlook, a state-of-the-art multicriteria optimization method for optimal design of supply chains with respect to multiple goals is described on a conceptual level.The supply chain design can be crucial for a successful post-project implementation. Its design can heavily influence the total supply cost and the quality of the delivered biomass to the SHS plants, thus the quality of the final product.Further steps are to set up case studies, and to evaluate them in different operational environments by using the suggested simulation model. It is important that such analyses are based on realistic and meaningful data to be able to draw conclusions.

description: We provide new ionization correction factors (ICFs) for carbon, nitrogen, neon, sulfur, chlorine, and argon in giant H II regions. The ICFs were computed using the most representative photoionization models from a large initial grid. The models were selected using an observational sample of 985 giant H II regions (GHR) in spiral galaxies and blue compact galaxies (BCG). The observational sample was also used to assign a weight to each model describing how well it agrees with observations in the [O III]/Hbeta versus [N II]/Halpha diagram. In addition to the ICFs we provide, for the first time, analytical expressions for their formal uncertainties. We use our ICFs to compute the abundances of nitrogen, neon, sulfur, and argon in our samples. Our abundances are robust within the adopted framework, but may require revision in the case of important changes in atomic data or in the spectral energy distribution of the ionizing radiation in H II regions. Considering the abundance patterns we obtained for the BCG sample (abundances for the GHR sample are less reliable) we find that oxygen is depleted into dust grains at a rate increasing with metallicity and reaching 0.12 dex at solar abundances. The discussion of possible depletion of sulfur and argon requires considering recent Type Ia Supernova yields, which are still uncertain.

description: Any group $G$ gives rise to a 2-group of inner automorphisms, $\mathrm{INN}(G)$. It is an old result by Segal that the nerve of this is the universal $G$-bundle. We discuss that, similarly, for every 2-group $G_{(2)}$ there is a 3-group $\mathrm{INN}(G_{(2)})$ and a slightly smaller 3-group $\mathrm{INN}_0(G_{(2)})$ of inner automorphisms. We describe these for $G_{(2)}$ any strict 2-group, discuss how $\mathrm{INN}_0(G_{(2)})$ can be understood as arising from the mapping cone of the identity on $G_{(2)}$ and show that its underlying 2-groupoid structure fits into a short exact sequence $G_{(2)} \to \mathrm{INN}_0(G_{(2)}) \to ΣG_{(2)}$. As a consequence, $\mathrm{INN}_0(G_{(2)})$ encodes the properties of the universal $G_{(2)}$ 2-bundle.

We present an algorithm that, given X and a tolerance Tol on the data error, computes a set G of polynomials such that each element of G "almost vanishing" at X and at all its equivalent sets X*. Even if G is not, in the general case, a basis of the vanishing ideal I(X), we show that, differently from the basis of I(X) that can be greatly influenced by the data uncertainty, G can determine a geometrical configuration simultaneously characterizing the set X and all its equivalent sets X*.

description: On-device training is an emerging approach in machine learning where models are trained on edge devices, aiming to enhance privacy protection and real-time performance. However, edge devices typically possess restricted computational power and resources, making it challenging to perform computationally intensive model training tasks. Consequently, reducing resource consumption during training has become a pressing concern in this field. To this end, we propose SCoTTi (Save Computation at Training Time), an adaptive framework that addresses the aforementioned challenge. It leverages an optimizable threshold parameter to effectively reduce the number of neuron updates during training which corresponds to a decrease in memory and computation footprint. Our proposed approach demonstrates superior performance compared to the state-of-the-art methods regarding computational resource savings on various commonly employed benchmarks and popular architectures, including ResNets, MobileNet, and Swin-T.

description: Photonic crystal slabs are the state of the art in studies for the light confinement, optical wave modulating and guiding, as well as nonlinear optical response. Previous studies have shown abundant real-world implementations of photonic crystals in planar optics, metamaterials, sensors, and lasers. Here, we report a novel full 2π phase control method in the reflected light beam over the interaction with a photonic crystal resonant mode, verified by the temporal coupled-mode analysis and S-parameter simulations. Enhanced by the asymmetric coupling with the output ports, the 2π phase shift can be achieved with the silicon photonics platforms such as Silicon-on-Silica and Silicon-on-Insulator heterostructures. Such photonic crystal phase control method provides a general guide in the design of phase-shift metamaterials, suggesting a wide range of applications in the field of sensing, spatial light modulation, and beam steering.

description: A comprehensive study of the two-dimensional (2D) compass model on the square lattice is performed for classical and quantum spin degrees of freedom using Monte Carlo and quantum Monte Carlo methods. We employ state-of-the-art implementations using Metropolis, stochastic series expansion and parallel tempering techniques to obtain the critical ordering temperatures and critical exponents. In a pre-investigation we reconsider the classical compass model where we study and contrast the finite-size scaling behavior of ordinary periodic boundary conditions against annealed boundary conditions. It is shown that periodic boundary conditions suffer from extreme finite-size effects which might be caused by closed loop excitations on the torus. These excitations also appear to have severe effects on the Binder parameter. On this footing we report on a systematic Monte Carlo study of the quantum compass model. Our numerical results are at odds with recent literature on the subject which we trace back to neglecting the strong finite-size effects on periodic lattices. The critical temperatures are obtained as $T_\mathrm{c}=0.1464(2)J$ and $T_\mathrm{c}=0.055(1)J$ for the classical and quantum version, respectively, and our data support a transition in the 2D Ising universality class for both cases.

description: A path-integral for the t-J model in two dimensions is constructed based on Dirac quantization, with an action found originally by Wiegmann (Phys. Rev. Lett. {\bf 60}, 821 (1988); Nucl. Phys. B323, 311 (1989)). Concentrating on the low doping limit, we assume short range antiferromagnetic order of the spin degrees of freedom. Going over to a local spin quantization axis of the dopant fermions, that follows the spin degree of freedom, staggered CP$^1$ fields result and the constraint against double occupancy can be resolved. The staggered CP$^1$ fields are split into slow and fast modes, such that after a gradient expansion, and after integrating out the fast modes and the dopant fermions, a CP$^1$ field-theory with a massive gauge field is obtained that describes generically incommensurate coplanar magnetic structures, as discussed previously in the context of frustrated quantum antiferromagnets. Hence, the possibility of deconfined spinons is opened by doping a colinear antiferromagnet.

Evoluzione storica, concezione costruttiva e principi per la conservazione degli antichi ponti

description: La ricerca svolta ha affrontato sia il complesso problema dello studio della concezione costruttiva degli antichi ponti, sia quello della definizione dei principi e dei criteri per la loro conservazione. 	Dopo aver evidenziato su diversi piani il valore emblematico del ponte, si è analizzata la sua evoluzione dall’antichità ai giorni nostri attraverso una breve storia che tende a guardare principalmente agli aspetti costruttivi. Si è poi passati all’analisi della concezione costruttiva antica dei ponti ed in particolare di quelli in muratura, mettendo in evidenza sia il permanere di una tipologia costruttiva che va dall’antica Roma a tutto il XIX secolo, sia il valore di costruzione archeologica che il ponte in muratura ha assunto rispetto alla concezione strutturale dell’architettura moderna. La ricerca ha poi dimostrato le grandi capacità strutturali degli antichi costruttori attraverso due insigni esempi: i ponti in legno di Palladio, ed il grande progetto di un ponte ad arco in muratura sul Bosforo di Leonardo da Vinci. In entrambi i casi si è dimostrata la loro piena affidabilità statica nel rispetto di modelli della moderna ingegneria strutturale. Inoltre, al fine di dimostrare la validità della concezione costruttiva romana dei ponti in muratura, testimoniata da una millenaria durabilità, si è preso in esame il comportamento strutturale del ponte di Porto Torres in Sardegna, che si è conservato fondamentalmente integro nonostante sia stato sottoposto fino a tempi recenti ad un intenso traffico di tipo industriale.
Riconosciuti vuoi il valore emblematico dei ponti antichi, vuoi il loro valore di storia materiale, vuoi ancora la centralità della loro concezione strutturale nella storia del costruire, si è passati ad esaminare, infine, le complesse problematiche connesse alla loro documentazione e conservazione. E’ stata quindi elaborata una scheda tipo che può costituire il prototipo di una banca dati, e sono stati forniti i criteri e le linee guida per favorire la conservazione dei ponti già dismessi e abbandonati, nonché di tanti altri che saranno dismessi per il rapido progredire della tecnologia.
La ricerca svolta è pertanto un contributo alla conservazione di una gloriosa tipologia costruttiva del patrimonio storico troppo spesso trascurata e incautamente abbandonata.

Thermal Capillary Wave Growth and Surface Roughening of Nanoscale Liquid Films

description: The well-known thermal capillary wave theory, which describes the capillary spectrum of the free surface of a liquid film, does not reveal the transient dynamics of surface waves, e.g., the process through which a smooth surface becomes rough. Here, a Langevin model is proposed that can capture these dynamics, goes beyond the long-wave paradigm which can be inaccurate at the nanoscale, and is validated using molecular dynamics simulations for nanoscale films on both planar and cylindrical substrates. We show that a scaling relation exists for surface roughening of a planar film and the scaling exponents belong to a specific universality class. The capillary spectra of planar films are found to advance towards a static spectrum, with the roughness of the surface $W$ increasing as a power law of time $W\sim t^{1/8}$ before saturation. However, the spectra of an annular film (with outer radius $h_0$) are unbounded for dimensionless wavenumber $qh_0<1$ due to the Rayleigh-Plateau instability.

description: A new generalization of the Calogero's rational ($A_N$) many-body quantum model is proposed and studied. The key innovation lies in an asymmetrization of the Calogero's two-body interaction. In the generalized model the exact solvability is preserved while the Calogeero's single coupling constant $C$ is replaced by a certain multiplet of freely variable parameters. The resulting Calogero-like Hamiltonian ceases to be re-arrangement-invariant. As a consequence, the degeneracy of the bound-state spectrum gets partially unfolded.

description: Even 100 years after its introduction by Louis de Broglie, the wave-nature of matter is often regarded as a mind-boggling phenomenon. To give an intuitive introduction to this field, we here discuss the diffraction of massive molecules through a single, double, and triple slit, as well as a nanomechanical grating. While the experiments are in good agreement with undergraduate textbook predictions, we also observe pronounced differences resulting from the molecules' mass and internal complexity. The molecules' polarizability causes an attractive van der Waals interaction with the slit walls, which can be modified by rotating the nanomechanical mask with respect to the molecular beam. The text is meant to introduce students and teachers to the concepts of molecule diffraction, supported by problems and solutions that can be discussed in class.

description: Atomic vapor of four different paramagnetic species: gold, silver, lithium, and rubidium, is produced and studied inside several buffer gases: helium, nitrogen, neon, and argon. The paramagnetic atoms are injected into the buffer gas using laser ablation. Wires with diameters 25 $μ$m, 50 $μ$m, and 100 $μ$m are used as ablation targets for gold and silver, bulk targets are used for lithium and rubidium. The buffer gas cools and confines the ablated atoms, slowing down their transport to the cell walls. Buffer gas temperatures between 20 K and 295 K, and densities between $10^{16}$ cm$^{-3}$ and $2\times10^{19}$ cm$^{-3}$ are explored. Peak paramagnetic atom densities of $10^{11}$ cm$^{-3}$ are routinely achieved. The longest observed paramagnetic vapor density decay times are 110 ms for silver at 20 K and 4 ms for lithium at 32 K. The candidates for the principal paramagnetic-atom loss mechanism are impurities in the buffer gas, dimer formation and atom loss on sputtered clusters.

description: Snow initialisation has been previously investigated as a potential source of predictability at the subseasonal-to-seasonal (S2S) timescales in winter and spring, through its local radiative, thermodynamical and hydrological feedbacks. However, previous studies were conducted with low-top models over short periods only. Furthermore, the potential role of the land surface–stratosphere connection upon the S2S predictability had remained unclear. To this end, we have carried out twin 30-member ensembles of 2-month (November–January) retrospective forecasts over the period 1985–2016, with either realistic or degraded snow initialisation. A high-top version of the Norwegian Climate Prediction Model is used, based on the Whole Atmosphere Community Climate Model, to insure improved coupling with the stratosphere. In a composite difference of high versus low initial Eurasian snow, the surface temperature is strongly impacted by the presence of snow, and wave activity fluxes into the stratosphere are enhanced at a 1-month lag, leading to a weakened polar vortex. Focusing further on 7 years characterized by a strongly negative phase of the Arctic Oscillation (AO), we find a weak snow feedback contributing to the maintenance of the negative AO. By comparing the twin forecasts, we extracted the predictive skill increment due to realistic snow initialisation. The prediction of snow itself is greatly improved and there is increased skill in surface temperature over snow-covered land at the 0-day lead time, and localized skill increment in the transition regions at the southern edge of the snow-covered land areas, over parts of midlatitude continents, at lead times longer than 30 days.

description: Herein, we depicted the crystal salt formation within silica hydrogel pores via antisolvent crystallization of thermally decomposable salts followed with the crystal salt decomposition for drying the hydrogel to aerogel at relatively low temperature and ambient pressure. Results showed that the dried silica with relatively large pore volume (e.g., 3.2 cm3/g), large surface area (e.g., 667.7 m2/g), small D50 (e.g., 6.9 μm) as well as narrow particle size distribution was obtained. The confined salt left mesopores when decomposed. In comparison with other salts and antisolvents, ammonium carbonate and isopropanol, respectively, showed remarkable improvement for the pore properties of the silica product. Furthermore, the as-dried silica as the coating flatting agent showed improved film transmittance and extinction indices when compared with a commercial sample.

description: An information-theoretic approach is proposed to watermark embedding and detection under limited detector resources. First, we consider the attack-free scenario under which asymptotically optimal decision regions in the Neyman-Pearson sense are proposed, along with the optimal embedding rule. Later, we explore the case of zero-mean i.i.d. Gaussian covertext distribution with unknown variance under the attack-free scenario. For this case, we propose a lower bound on the exponential decay rate of the false-negative probability and prove that the optimal embedding and detecting strategy is superior to the customary linear, additive embedding strategy in the exponential sense. Finally, these results are extended to the case of memoryless attacks and general worst case attacks. Optimal decision regions and embedding rules are offered, and the worst attack channel is identified.

description: We study the behavior of two-flavor dense quark matter under the influence of an external magnetic field in the framework of a nonlocal chiral quark model with separable interactions. The nonlocality is incorporated in the model by using a Gaussian form factor. It is found that for low and moderate values of magnetic field there is a decrease of the critical chiral restoration chemical potential $μ_c$, i.e. an inverse magnetic catalysis effect is observed. For larger values of $eB$ the behavior of $μ_c$ becomes more or less flat, depending on the parametrization. Within the considered parametrization range we do not find a significant growth of the critical chemical potential for large magnetic fields, as occurs in the case of the local NJL model.

description: In 2017, the German federal state of Hamburg decided to fund a development plan for Open Science, greatly supporting Openness in the local research landscape. It affects three types of users: researchers, their institutions and the general public.

The Hamburg State and University Library carries out a project for building a central information hub, giving citizens, researchers and the media an overview of (open) science in Hamburg and a good starting point for further exploration and research. The project focusses on three main fields of activity: (meta-)data aggregation from repositories, research data management systems, and CRISes, providing a discovery system and the creation of useful edited content for the portal.

While the task of building an aggregation and discovery service is not new, the presentation of local science aimed at a local public allows for a different presentation of the scientific data.

Since our project endorses openness, almost all of our sourcecode is published on Github and can freely be used by other projects.
Kinetic powers of the relativistic jets in Mrk 421 and Mrk 501

description: Using the standard one-zone synchrotron self-Compton (SSC) model and the Markov chain Monte Carlo (MCMC) technique, we systematically analyze the quasi-simultaneous multi-wavelength (MWL) spectral energy distributions (SEDs) of Mrk 421 and Mrk 501 during states of relatively low activity. With this model in place, a semi-analytical method is developed to examine the uncertainty in jet power estimation caused by degeneracy of the radiative models. The semi-analytical method, in combination with the MCMC technique, allows us to explore the jet properties over a wide range of the variability timescale. Our results seem to support: (1) In both Mrk 421 and Mrk 501 the jets are powered by rapidly rotating black holes (BHs). The BH spin in Mrk 501 could be lower than that in Mrk 421 or possibility they are equal under the assumption of Blandford-Znajek mechanism. (2)The energy losses, which could be used to form the large-scale radio structure, are important for reconciling the differences of the kinetic power derived from the observations of the large-scale structure and the SED fitting results. Moreover, the jet energy losses in the propagation are more significant for Mrk 501 than for Mrk 421.

Effective Action and Electromagnetic Polarizabilities of Nucleons in QCD String Theory

Publisher: name: arXiv
Year: 1999
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The effective action for baryons in the external electromagnetic fields is obtained on the basis of the QCD string theory. The area law of the Wilson loop integral, the approximation of the Nambu-Goto straight-line strings, and the asymmetric quark-diquark structure of nucleons are used to simplify the problem. The spin-orbit and spin-spin interactions of quarks are treated as a perturbation. With the help of the virial theorem we estimate the mean radii of nucleons in terms of the string tension and the Airy function zeros. On the basis of the perturbation theory in small external electromagnetic fields we derive the electromagnetic polarizabilities of nucleons. The electric and diamagnetic polarizabilities of a proton are $\barα_p= 10\times 10^{-4} fm^3$, $β_p^{dia}=-8\times 10^{-4} fm^3$ and for a neutron we find $\barα_n=4.2\times 10^{-4} fm^3 $, $β_n^{dia}= -5.4\times 10^{-4} fm^3$. Reasonable values of the magnetic polarizabilities $\barβ_p=(5\pm 3)\times 10^{-4} fm^3$, $\barβ_n=(7.6\pm 3)\times 10^{-4} fm^3$ are estimated using the $Δ$ contribution to the paramagnetic polarizability of the nucleons.

description: I suggest wave equations for the scalar, pseudoscalar, vector, and pseudovector fields with different masses for spin zero and one states. Tensor, matrix, and quaternion formulations of fields with two mass and spin states are considered. This is the generalization of the Dirac-Kähler equation on the case of different masses of fields with spin one and zero. The equation matrices obtained are simple linear combinations of matrix elements in the 16-dimensional space. Spin projection operators and solutions of equations (for spin one) in the form of matrix-dyads are obtained. The canonical quantization of fields under consideration is studied. The anomalous interaction of the scalar, pseudoscalar, vector, and pseudovector fields with the external electromagnetic field is considered. Three constants which characterize the anomalous magnetic moment and quadrupole electric moment of a particle are introduced.
