description: Water movement in unsaturated soils gives rise to measurable electrical potential differences that are related to the flow direction and volumetric fluxes, as well as to the soil properties themselves. Laboratory and field data suggest that these so-called streaming potentials may be several orders of magnitudes larger than theoretical predictions that only consider the influence of the relative permeability and electrical conductivity on the self potential (SP) data. Recent work has partly improved predictions by considering how the volumetric excess charge in the pore space scales with the inverse of water saturation. We present a new theoretical approach that uses the flux-averaged excess charge, not the volumetric excess charge, to predict streaming potentials. We present relationships for how this effective excess charge varies with water saturation for typical soil properties using either the water retention or the relative permeability function. We find large differences between soil types and the predictions based on the relative permeability function display the best agreement with field data. The new relationships better explain laboratory data than previous work and allow us to predict the recorded magnitudes of the streaming potentials following a rainfall event in sandy loam, whereas previous models predict three orders of magnitude too small values. We suggest that the strong signals in unsaturated media can be used to gain information about fluxes (including very small ones related to film flow), but also to constrain the relative permeability function, the water retention curve, and the relative electrical conductivity function.

description: It has long been speculated that the nature of the hard X-ray corona may be an important second driver of black hole state transitions, in addition to the mass accretion rate through the disk. However, a clear physical picture of coronal changes has not yet emerged. We present results from a systematic analysis of Rossi X-ray Timing Explorer observations of the stellar mass black hole binary XTE J1650-500. All spectra with significant hard X-ray detections were fit using a self-consistent, relativistically-blurred disk reflection model suited to high ionization regimes. Importantly, we find evidence that both the spectral and timing properties of black hole states may be partially driven by the height of the X-ray corona above the disk, and related changes in how gravitational light bending affects the corona--disk interaction. Specifically, the evolution of the power-law, thermal disk, and relativistically--convolved reflection components in our spectral analysis indicate that: (1) the disk inner radius remains constant at \rin$=1.65\pm0.08 GM/c^2$ (consistent with values found for the ISCO of XTE J1650-500 in other works) throughout the transition from the \textit{brighter} phases of the low-hard state to the intermediate states (both the hard-intermediate and soft-intermediate), through to the soft state and back; (2) the ratio between the observed reflected X-ray flux and power-law continuum (the "reflection fraction", R) increases sharply at the transition between the hard-intermediate and soft-intermediate states ("ballistic" jets are sometimes launched at this transition); (3) both the frequency and coherence of the high-frequency quasi-periodic oscillations (QPOs) observed in XTE J1650-500 increase with R. We discuss our results in terms of black hole states and the nature of black hole accretion flows across the mass scale.

description: We perform quantum Monte Carlo (QMC) calculations to determine minimum energy pathways of simple chemical reactions, and compare the computed geometries and reaction barriers with those obtained with density functional theory (DFT) and quantum chemistry methods. We find that QMC performs in general significantly better than DFT, being also able to treat cases in which DFT is inaccurate or even unable to locate the transition state. Since the wave function form employed here is particularly simple and can be transferred to larger systems, we suggest that a QMC approach is both viable and useful for reactions difficult to address by DFT and system sizes too large for high level quantum chemistry methods.

description: This contribution (in Italian) arises from the experience of group analysis work within the project "Le culture di Linux e dell'open source" coordinated by Piero Polidoro at the University of Rome - LUMSA. The project required both work among semiotic analysts and dialogue with scholars from other disciplines. This experience led me to question the teamwork dimension in semiotics: a dimension that, together with technologically-assisted analysis, is necessary when tackling the analysis of vast and complex corpora in interdisciplinary contexts. The problem of analyzing large corpora has already been the subject of some reflections, including at recent conferences of the Italian Association of Semiotic Studies (I remember, in particular, the 43rd AISS conference on "New forms of interaction: from the web to mobile", held in Bologna in September 2015, which had many interventions on the semiotic treatment of big data). However, the most recent reflection has always focused on the corpus side - that is, on the construction of the object of analysis - and never on the modes of group work: what is the status of teamwork in semiotics? How can large corpora be analyzed with a semiotic methodology, taking into account the possibility of using technologies? In the first paragraph, I will reconstruct the terms of the debate starting from the works of Algirdas Julien Greimas and Umberto Eco; in the second paragraph, I will frame the issue in an interdisciplinary context, indicating a possible path of development for methodological reflection on these themes.

Parametricity in an Impredicative Sort

Subjects: subject: Logic in Computer Science (cs.LO)
subject: FOS: Computer and information sciences

description: Reynold's abstraction theorem is now a well-established result for a large class of type systems. We propose here a definition of relational parametricity and a proof of the abstraction theorem in the Calculus of Inductive Constructions (CIC), the underlying formal language of Coq, in which parametricity relations' codomain is the impredicative sort of propositions. To proceed, we need to refine this calculus by splitting the sort hierarchy to separate informative terms from non-informative terms. This refinement is very close to CIC, but with the property that typing judgments can distinguish informative terms. Among many applications, this natural encoding of parametricity inside CIC serves both theoretical purposes (proving the independence of propositions with respect to the logical system) as well as practical aspirations (proving properties of finite algebraic structures). We finally discuss how we can simply build, on top of our calculus, a new reflexive Coq tactic that constructs proof terms by parametricity.

We show, explicitly for the B-L-SSM, that these contributions can play a crucial role in the explanation of the enhanced diphoton decay rate of a SM-like Higgs particle around 125 GeV. Even in the most constrained scenario with universal scalar and gaugino masses, it is possible to obtain a sizable enhancement and, in addition, the correct relic density for the LSP. Furthermore, a lighter CP-even scalar that could fit the LEP excess at 98 GeV is viable.

description: The accurate characterization of eigenmodes and eigenfrequencies of two-dimensional ion crystals provides the foundation for the use of such structures for quantum simulation purposes. We present a combined experimental and theoretical study of two-dimensional ion crystals. We demonstrate that standard pseudopotential theory accurately predicts the positions of the ions and the location of structural transitions between different crystal configurations. However, pseudopotential theory is insufficient to determine eigenfrequencies of the two-dimensional ion crystals accurately but shows significant deviations from the experimental data obtained from resolved sideband spectroscopy. Agreement at the level of 2.5 x 10^(-3) is found with the full time-dependent Coulomb theory using the Floquet-Lyapunov approach and the effect is understood from the dynamics of two-dimensional ion crystals in the Paul trap. The results represent initial steps towards an exploitation of these structures for quantum simulation schemes.

Transverse kink oscillations of expanding coronal loops

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: We investigate the nature of transverse kink oscillations of loops expanding through the solar corona and how can oscillations be used to diagnose the plasma parameters and the magnetic field. In particular, we aim to analyse how the temporal dependence of the loop length (here modelling the expansion) will affect the P1 /P2 period ratio of transverse loop oscillations. Due to the uncertainty of the loop's shape through its expansion, we discuss separately the case of the loop that maintains its initial semi-circular shape and the case of the loop that from a semi-circular shape evolve into an elliptical shape loop. The equations that describe the oscillations in expanding flux tube are complicated due to the spatial and temporal dependence of coefficients. Using the WKB approximation we find approximative values for periods and their evolution, as well as the period ratio. For small values of time (near the start of the expansion) we can employ a regular perturbation method to find approximative relations for eigenfunctions and eigenfrequencies. Using simple analytical and numerical methods we show that the period of oscillations are affected by the rising of the coronal loop. The change in the period due to the increase in the loop's length is more pronounced for those loops that expand into a more structured (or cooler corona). The deviation of periods will have significant implications in determining the degree of stratification in the solar corona. The effect of expansion on the periods of oscillations is considerable only in the process of expansion of the loop but not when it reached its final stage.

description: We consider generic interacting chain of qubits, which are coupled at the edges to baths of fixed polarizations. We can determine the nonequilibrium steady states, described by the fixed point of the Lindblad Master Equation. Under rather general assumptions about local pumping and interactions, symmetries of the reduced density matrix are revealed. The symmetries drastically restrict the form of the steady density matrices in such a way that an exponentially large subset of one--point and many--point correlation functions are found to vanish. As an example we show how in a Heisenberg spin chain a suitable choice of the baths can completely switch off either the spin or the energy current, or both of them, despite the presence of large boundary gradients.

title: Engineering of Aerosol-Jet Printed Carbon Nanotube Network Transistors
Creators: name: Rother, Marcel
Publisher: name: Heidelberg University Library
Year: 2019

description: Thanks to their extremely high mobilities, semiconducting carbon nanotubes (CNTs) are a promising material for high speed electronics. Beyond that, CNT networks are inherently flexible and stretchable and can be processed from dispersions resulting in devices with still remarkable electronic properties. They can fulfill many of the various requirements for novel applications including fast switching speeds and high currents at low drive voltages. Depending on the intended use, one or another device property might be more important. CNT networks, processes, and architectures can be tailored to yield devices that can serve the respective purpose. Highly purified semiconducting CNTs are, however, still rather expensive and direct-write techniques are thus preferred to enable variable designs and reduce manufacturing costs.
In this work, aerosol-jet printing is investigated as a deposition technique for CNTs that works with small ink volumes but can also be upscaled by parallelization and integrated into high-throughput roll-to-roll printing processes. After the development of printable inks, it is shown that the printing process itself has no influence on the quality of the CNTs although sonication is used to transfer the ink into an aerosol. The electronic properties of CNT networks incorporated in an established transistor structure exhibit reproducibility comparable to other deposition techniques. Moreover, additive manufacturing enables the deposition of several layers on top of each other to increase the overall film thickness up to optically dense films visible to the naked eye. Field-effect mobilities and on-conductances increase and the hysteresis decreases for thicker films compared to dense but thin networks. 
Based on these findings, CNT films are printed with a thickness of 50–600 nm and vertical charge transport is demonstrated. These films are subsequently sandwiched between electrodes and electrolyte-gating results in doping of CNT films throughout electrode overlap areas of several hundred µm2. The vertical device architecture decouples the printing accuracy from the critical device dimensions while supporting high currents for a small footprint. A comparison of different printed electrode materials reveals the superior properties of printed metals over mixed (metallic and semiconducting) CNTs. Electrodes based on inkjet-printed gold nanoparticles are additionally used on flexible substrates and stable device performance even after several hundred bending cycles is demonstrated for vertical and lateral CNT network transistors. These all-printed devices are promising for further development of electronic circuits that do not require high operating frequencies but rather flexibility, high-currents, and small footprints.

description: Magnetometry measurements in high quality LiFeAs single-crystals reveal a change in the sign of the magnetic hysteresis in the vicinity of the upper critical field $H_{c2}$, from a clear diamagnetic response dominated by the pinning of vortices, to a considerably smaller net hysteretic response of opposite sign, which \emph{disappears} at $H_{c2}$. If the diamagnetic response at high fields results from pinned vortices and associated screening super-currents, this sign change must result from currents circulating in the opposite sense, which give rise to a small field-dependent magnetic moment \emph{below} $H_{c2}$. This behavior seems to be extremely sensitive to the sample quality or stoichiometry, as we have observed it only in a few fresh crystals, which also display the de Haas van Alphen-effect. We provide arguments against the surface superconductivity, the flux compression, and the random $π$ junction scenarios, which have been previously put forward to explain a paramagnetic Meissner effect, below the lower critical field $H_{c1}$. The observed anomalous hysteresis at high fields will be compatible with the existence of chiral gap wave-functions, which possess a field dependent magnetic moment. Within a Landau-Ginzburg framework, we demonstrate how a $(d_{x^2 - y^2} + id_{xy})$ or a $(p_x+ip_y)$ chiral superconducting component can be stabilized in the mixed state of $s_{\pm}$ superconductor, due to the combined effects of the magnetic field and the presence of competing pairing channels. The realization of a particular chiral pairing depends on the microscopic details of the strengths of the competing pairing channels.

description: A substantial fraction of the total stellar mass in rich clusters of galaxies resides in a diffuse intergalactic component usually referred to as the Intra-Cluster Light (ICL). Theoretical models indicate that these intergalactic stars originate mostly from the tidal interaction of the cluster galaxies during the assembly history of the cluster, and that a significant fraction of these stars could have formed in-situ from the late infall of cold metal-poor gas clouds onto the cluster. The models make predictions about the age distribution of the ICL stars, which may provide additional observational constraints. However, these models also over-predict the fraction of stellar mass in the ICL by a substantial margin. Here we present population synthesis models for the ICL of a dumb-bell dominated intermediate redshift (z=0.29) X-ray cluster for which we have deep MOS data obtained with the FORS2 instrument. In a previous paper we have proposed that the dumbell galaxy act as a grinding machine tearing to pieces the galaxies that pass nearby thus enriching the intergalactic medium. In this paper we analyze the spectra at different locations within the ICL and find that it is dominated by old metal rich stars, at odds with what has been found in nearby clusters where the stars that dominate the ICL are old and metal poor. While we see a weak evidence of a young, metal poor, component, if real, these young stars would amount to less than 1% of the total ICL mass, much less than the up to 30% predicted by the models. We propose that the very metal rich (i.e. 2.5 times solar) stars in the ICL of our cluster, which comprise approximately 40% of the total mass, originate mostly from the central dumb-bell galaxy, while the remaining solar and metal poor stars come from spiral, post-starburst (E+A), and metal poor dwarf galaxies. About 16% of the ICL stars are old and metal poor.

description: Let $(M,ω)$ be an almost symplectic manifold ($ω$ is a non degenerate, not closed, 2-form). We say that a vector field $X$ of $M$ is locally Hamiltonian if $L_Xω=0,d(i(X)ω)=0$, and it is Hamiltonian if, furthermore, the 1-form $i(X)ω$ is exact. Such vector fields were considered in a 2007 paper by F. Fasso and N. Sansonetto, under the name of strongly Hamiltonian, and a corresponding action-angle theorem was proven. Almost symplectic manifolds may have few, non-zero, Hamiltonian vector fields or even none. Therefore, it is important to have examples and it is our aim to provide such examples here. We also obtain some new general results. In particular, we show that the locally Hamiltonian vector fields generate a Dirac structure on $M$ and we state a reduction theorem of the Marsden-Weinstein type. A final section is dedicated to almost symplectic structures on tangent bundles.

description: We consider the tension-induced non-linearities of mechanical resonators, and derive the Hamiltonian of the flexural modes up to the fourth order in the position operators. This tension can be controlled by a nearby gate voltage. We focus on systems which allow large deformations $u(x)\gg h$ compared to the thickness $h$ of the resonator and show that in this case the third-order coupling can become non-zero due to the induced dc deformation and offers the possibility to realize equations of motion encountered in optomechanics. The fourth-order coupling is relevant especially for relatively low voltages. It can be detected by accessing the Duffing regime, and by measuring frequency shifts due to mode-mode coupling.

description: Single crystals of the LnFeAsO (Ln1111, Ln = Pr, Nd, and Sm) family with lateral dimensions up to 1 mm were grown from NaAs and KAs flux at high pressure. The crystals are of good structural quality and become superconducting when O is partially substituted by F (PrFeAsO1-xFx and NdFeAsO1-xFx) or when Fe is substituted by Co (SmFe1-xCoxAsO). From magnetization measurements, we estimate the temperature dependence and anisotropy of the upper critical field and the critical current density of underdoped PrFeAsO0.7F0.3 crystal with Tc = 25 K. Single crystals of SmFe1-xCoxAsO with maximal Tc up to 16.3 K for x = 0.08 were grown for the first time. From transport and magnetic measurements we estimate the critical fields and their anisotropy, and find these superconducting properties to be quite comparable to the ones in SmFeAsO1-xFx with a much higher Tc of = 50 K. The magnetically measured critical current densities are as high as 109 A/m2 at 2 K up to 7 T, with indication of the usual fishtail effect. The upper critical field estimated from resistivity measurements is anisotropic with slopes of -8.7 T/K (H // ab-plane) and -1.7 T/K (H // c-axis). This anisotropy (= 5) is similar to that in other Ln1111 crystals with various higher Tc s.

description: QCD can be formulated using any gauge group. One particular interesting choice is to replace SU(3) by the exceptional group G2. Conceptually, this group is the simplest group with a trivial center. It thus permits to study the conjectured relevance of center degrees of freedom for QCD. Practically, since all its representation are real, it is possible to perform lattice simulations for this theory also at finite baryon densities. It is thus an excellent environment to test methods and to investigate general properties of gauge theories at finite densities. We review the status of our understanding of gauge theories with the gauge group G2, including Yang-Mills theory, Yang-Mills-Higgs theory, and QCD both in the vacuum and in the phase diagram.

description: Abstract
Osteoporosis (OP) is a widespread metabolic disease of the skeleton, leading to decreased bone strength and increased risk of fractures. OP is a disease of varying nature that affects all age groups, but is most common in older people. For a long time, doctors did not have serious tools to treat this insidious disease and mainly dealt with its consequences - fractures. We have witnessed the birth of a new group of drugs—bisphosphonates (BPs), which have significantly expanded the capabilities of clinicians in the treatment of OP and a number of other bone diseases, as well as calcium metabolism disorders. Modern medicine is based on a solid evidence base. All drugs recommended for use in clinical practice are subject to long-term, multi-stage clinical studies of effectiveness and safety. Possessing different biological activities, these drugs demonstrated one common property in clinical trials, which allowed them to be recommended for the treatment of OP: reducing the risk of fractures. The purpose of the study is to evaluate the effectiveness of bisphosphonates in the treatment of patients with OP in the climacteric period. From 2020 to 2022, 105 climacteric female patients with a confirmed diagnosis of OP of the knee joint, registered in the arthrological IADC department of the multidisciplinary clinic of the Tashkent Medical Academy (TMA), receiving inpatient treatment in the departments of cardiorheumatology and rheumatology, were involved in this research work. They analyzed the clinical course of the disease and the results of laboratory and instrumental examinations. For prospective analysis, the patients were divided into two groups: Group I consisted of female patients with premenopausal OP. Group II consisted of postmenopausal female patients with OP during menopause. In the obtained results, the clinical and laboratory activity indicators of the disease reliably decreased in a statistically significant manner in the group of patients treated with bisphosphonates compared to traditional treatment. Also, indicators of endothelial dysfunction were improved. In UVD and MRI, degenerative changes in bones and joints showed positive dynamics. In conclusion, in the treatment of OP patients in the climacteric period, the use of bisphosphonates (Zoledronic acid) in addition to traditional treatment reduces the frequency of degenerative changes in the joints by reducing the clinical laboratory activity level of the disease, improving endothelial dysfunction, and improving the quality of life of patients.

description: The presence of a nearby companion alters the evolution of massive stars in binary systems, leading to phenomena such as stellar mergers, X-ray binaries and gamma-ray bursts. Unambiguous constraints on the fraction of massive stars affected by binary interaction were lacking. We simultaneously measured all relevant binary characteristics in a sample of Galactic massive O stars and quantified the frequency and nature of binary interactions. Over seventy per cent of all massive stars will exchange mass with a companion, leading to a binary merger in one third of the cases. These numbers greatly exceed previous estimates and imply that binary interaction dominates the evolution of massive stars, with implications for populations of massive stars and their supernovae.
