description: [The Tabulae of Brigetio and Durostorum. A constitution on the privileges of milites and veterans: the status quaestionis]. My research focuses on the main issues derived from the study of the Tabulae of Brigetio and Durostorum, in particular: the grant of tax privileges to soldiers and the supposed reform on the practice of issuing the military diplomas. On the latter point, I propose a different theory: the constitution transcribed in these tables introduced a new practice concerning the regular concession of the tabulae honestae missionis.

description: Four patients with epidermolysis bullosa acquisita were investigated using immunofluorescence, routine electron microscopic and immunoelectron microscopic techniques. Immunofluorescence studies demonstrated linear immunoglobulin and complement deposition along the dermal-epidermal junction. These findings are similar to those seem in skin of patients with bullous acquisita from that seen in bullous pemphigoid. Indirect immunoelectron microscopic findings suggest that epidermal basal cells of affected patients may secrete the dermal substances to which the antibodies bind.

description: Collaborative filtering (CF) is widely searched in recommendation with various types of solutions. Recent success of Graph Convolution Networks (GCN) in CF demonstrates the effectiveness of modeling high-order relationships through graphs, while repetitive graph convolution and iterative batch optimization limit their efficiency. Instead, item similarity models attempt to construct direct relationships through efficient interaction encoding. Despite their great performance, the growing item numbers result in quadratic growth in similarity modeling process, posing critical scalability problems. In this paper, we investigate the graph sampling strategy adopted in latest GCN model for efficiency improving, and identify the potential item group structure in the sampled graph. Based on this, we propose a novel item similarity model which introduces graph partitioning to restrict the item similarity modeling within each partition. Specifically, we show that the spectral information of the original graph is well in preserving global-level information. Then, it is added to fine-tune local item similarities with a new data augmentation strategy acted as partition-aware prior knowledge, jointly to cope with the information loss brought by partitioning. Experiments carried out on 4 datasets show that the proposed model outperforms state-of-the-art GCN models with 10x speed-up and item similarity models with 95\% parameter storage savings.

description: We calculate the long-wavelength static screening properties of both neutral and doped graphene in the framework of density-functional theory. We use a plane-wave approach with periodic images in the third dimension and truncate the Coulomb interactions to eliminate spurious interlayer screening. We carefully address the issue of extracting two dimensional dielectric properties from simulated three-dimensional potentials. We compare this method with analytical expressions derived for two dimensional massless Dirac fermions in the random phase approximation. We evaluate the contributions of the deviation from conical bands, exchange-correlation and local-fields. For momenta smaller than twice the Fermi wavevector, the static screening of graphene within the density-functional perturbative approach agrees with the results for conical bands within random phase approximation and neglecting local fields. For larger momenta, we find that the analytical model underestimates the static dielectric function by $\approx 10%$, mainly due to the conical band approximation.

description: [Mobility between Army, City Senates and Bureaucracy in the Legislation of the Emperor Valentinian] In the later Roman empire, the sons of soldiers were legally compelled to follow in their father's footsteps. However, several laws of Valentinian I from the years 371-2 show how in practice the constraints were far less rigid than the imperial constitutions themselves prescribed. Sons of veterans are attested within the city senates or in service in the offices of the bureaucracy; likewise, officiales made their entry into the army. The imperial chancellery recognized the legitimacy of some of these situations which, while contradicting the principle of the inheritance of the function, had to prove advantageous for the same authority.

Biochemical Composition of the Epidermal-dermal Junction and Other Basement Membrane
Creators: name: Briggaman, Robert A.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1982

description: The epidermo-dermal junction ultrastructurally appears to be high organized, presenting 4 layers: (1) the basal cell plasma membrane, a trilaminar layer with special attachment structures (hemidesmosomes); (2) lamina lucida (rara) an electron-lucent zone with 'anchoring' filaments (vide infra); (3) basal lamina (densa) electron-dense and relatively thick (30-50 nm) and (4) the subbasal fibrous area, composed of 3 different fibrils: (a) 'anchoring fibrils' meshing with the lamina densa upwards and forming and interlocking (a) meshwork with the adjacent anchoring fibrils downwards; (b) dermal microfibril bundles starting from the basal lamina and passing deep in the dermis. The dermal part of these, are in connection with the elastic fibers and ultrastructurally they are identical and; (c) collagen fibers, randomly oriented without connection with the basal lamina. The biochemical composition comprises collagenous and noncollagenous substances: collagens can be divided into 3 groups designated as type IV collagen, type V(AB collagen) and 7S collagen. The non-collagenous materials as yet identified are: bullous pemphigoid antigen (reactive with the bullous pemphigoid antibodies), laminin, heparan-sulfate containing proteoglycan and amyloid P-component (a normal plasma constituent). Functional aspects of basement membrane components: (1) support of a caffolding function assumed by the collagens; (2) attachment of cells of different embryonic origin (fibronectin, PB antigen and laminin); (3)regulation of the permeability (heparan-sulfate proteoglycan and other glycosaminoglycans); and (4) a role in development and morphogenesis (laminin) and type IV collagen). This paper must be read in extenso by those interested in the microstructure and functions of the skin. (I. Capusan - Cluj)

description: [The end of De rebus bellicis: ideological, juridical and linguistic aspects] The De rebus bellicis, probably written by an Anonymous member of the upper class who lived during the second half of the fourth century, represents a fundamental text to understand several aspects of the Late Antiquity, although, due to its not easy historical and literary collocation, it is a rarely mentioned work, even among scholars of law. As shown by the title, military themes constitute the framework of the treaty, however the concluding section is characterized by a brief, but meaningful mention of the juridical problems of the time: this contribution contains a proposal of analysis of these words.

This paper aims to discuss the more relevant problems concerning the history of the most important military corps stationed in Rome, the vigiles, the urbaniciani, the equites singulares Augusti and the praetorians, in a period of time included between Diocletian rise and Constantine death. The closer examination of the sources shows that the rise of Diocletian was not the beginning of the decline of the Rome’s units, as claimed by some modern scholars.

description: The standard model has postulated the existence of a scalar boson, named the Higgs boson. This boson plays a central role in a symmetry breaking scheme called the Brout-Englert-Higgs mechanism (or the Brout-Englert-Higgs-Guralnik-Hagen-Kibble mechanism, for completeness) making the standard model realistic. However, until recently at least, the 50-year-long-sought Higgs boson had remained the only particle in the standard model not yet discovered experimentally. It is the last but very important missing ingredient of the standard model. Therefore, searching for the Higgs boson is a crucial task and an important mission of particle physics. For this purpose, many theoretical works have been done and different experiments have been organized. It may be said in particular that to search for the Higgs boson has been one of the ultimate goals of building and running the LHC, the world's largest and most powerful particle accelerator, at CERN, which is a great combination of science and technology. Recently, in the summer of 2012, ATLAS and CMS, the two biggest and general-purpose LHC collaborations, announced the discovery of a new boson with a mass around 125 GeV. Since then, for over two years, ATLAS, CMS and other collaborations have carried out intensive investigations on the newly discovered boson to confirm that this new boson is really the Higgs boson (of the standard model). It is a triumph of science and technology and international cooperation. Here, we will review the main results of these investigations following a brief introduction to the Higgs boson within the theoretical framework of the standard model and Brout-Englert-Higgs mechanism as well as a theoretical and experimental background of its search. This paper may attract interest of not only particle physicists but also a broader audience.

description: The MAJORANA DEMONSTRATOR searched for neutrinoless double-$β$ decay ($0νββ$) of $^{76}$Ge using modular arrays of high-purity Ge detectors operated in vacuum cryostats in a low-background shield. The arrays operated with up to 40.4 kg of detectors (27.2 kg enriched to $\sim$88\% in $^{76}$Ge). From these measurements, the DEMONSTRATOR has accumulated 64.5 kg yr of enriched active exposure. With a world-leading energy resolution of 2.52 keV FWHM at the 2039 keV $Q_{ββ}$ (0.12\%), we set a half-life limit of $0νββ$ in $^{76}$Ge at $T_{1/2}>8.3\times10^{25}$ yr (90\% C.L.). This provides a range of upper limits on $m_{ββ}$ of $(113-269)$ meV (90\% C.L.), depending on the choice of nuclear matrix elements.

description: One can use more than one scale variable to define the family of surfaces in the space of parton splitting parameters that define the evolution of a parton shower. In an earlier paper, we developed this idea for electron-positron annihilation. Here, we use multiple scale variables for a parton shower with initial state partons. Then we need a more sophisticated analysis because the evolution of parton distribution functions must be coordinated with the parton shower evolution. We make the needed connections more precise than in our earlier work, even for the case of just one scale variable. Then we develop an example with three scale variables, which leads to advantages compared to the usual shower formulation with only one scale variable. We provide results for Drell-Yan muon pair production.

For this purpose, the differential force between a Au-coated sphere and either Au or Si sectors of a rotating disc, arising due to two-axion exchange, is calculated. Over a wide region of axion masses from 1.7 meV to 0.9 eV the obtained constraints are stronger up to a factor of 60 than the previously known ones following from the Cavendish-type experiment and measurements of the effective Casimir pressure.

description: We study the mechanism of the triplet superconductivity (TSC) in Sr$_2$RuO$_4$ based on the multiorbital Hubbard model. The electronic states are studied using the recently developed renormalization group method combined with the constrained random-phase-approximation, called the RG+cRPA method. Thanks to the vertex correction (VC) for the susceptibility, which is dropped in the mean-field-level approximations, strong orbital and spin fluctuations at $Q \approx(2π/3,2π/3)$ emerge in the quasi one-dimensional Fermi surfaces (FSs) composed of $d_{xz}+d_{yz}$ orbitals. Due to the cooperation of both fluctuations, we obtain the triplet superconductivity in the $E_u$ representation, in which the superconducting gap is given by the linear combination of $(Δ_x(k),Δ_y(k))\sim (\sin 3k_x,\sin 3k_y)$. Very similar results are obtained by applying the diagrammatic calculation called the self-consistent VC method. Thus, the idea of "orbital+spin fluctuation mediated TSC" is confirmed by both RG+cRPA method and the self-consistent VC method. We also reveal that a substantial superconducting gap on the $d_{xy}$-orbital FS is induced from the gaps on the quasi one-dimensional FSs, in consequence of the large orbital-mixture due to the 4$d$ spin-orbit interaction.

description: [Some aspects of the personal legal status in the Roman army with special regard to the period of the III century AD]. The presented article covers a few issues that could be linked to the general topic of the personal status in the Roman army with a special regard for the period of transition towards the Late Antiquity – III century AD. An analysis is made of the different types of discharge from the army and the veteran’s certificate, given to the former soldiers. Some of the privileges, brought by this certificate upon the receiver are further researched, including the fact that it was a specific way of real estate acquisition. The second part of the article deals with the effect of military awards on the personal status and includes a short overview of their development through the centuries. Conclusions are made based on the analysis.

description: Topological invariance is a powerful concept in different branches of physics as they are particularly robust under perturbations. We generalize the ideas of computing the statistics of winding numbers for a specific parametric model of the chiral Gaussian Unitary Ensemble to other chiral random matrix ensembles. Especially, we address the two chiral symmetry classes, unitary (AIII) and symplectic (CII), and we analytically compute ensemble averages for ratios of determinants with parametric dependence. To this end, we employ a technique that exhibits reminiscent supersymmetric structures while we never carry out any map to superspace.
Functional Evidence for Complement-activating Immune Complexes in the Skin of Patients with Bullous Pemphigoid

description: Previous immunofluorescent studies showing deposits of immunoglobulin and complement at the cutaneous basement membrane zone have provided evidence supporting a role for immune complexes in the pathogenesis of bullous pemphigoid. In this study the functional activity of the deposits has been examined using leukocyte attachment, a method for detecting and quantitating the biological activity of complement-activating immune complexes in tissues. When peripheral blood leukocytes suspended in serum complement were incubated with cryostat sections of lesional and adjacent normal-appearing skin from 9 patients with pemphigoid, skin from 11 normal controls and lesional skin from 14 nonpemphigoid disease controls there was significantly greater attachment of leukocytes to the basement membrane zone of lesional bullous pemphigoid skin compared to normal-appearing pemphigoid skin and skin of both control groups. A significant reduction in attachment in the absence of serum complement suggested the reaction was dependent on activation of complement by tissue-deposited complexes. Although leukocyte attachment was greater in lesional than normal-appearing pemphigoid skin, a comparison of the incidence and intensity of cutaneous IgG and complement immunofluorescence between the 2 groups showed no significant differences. Furthermore, no correlation between leukocyte attachment and serum titers of immunoglobulin G or complement-binding anti-basement membrane zone antibodies was observed. These results suggest that immune reactants in lesional pemphigoid skin are functional complement-activating immune complexes, that differences exist between the activity of complexes in lesional and normal-appearing pemphigoid skin and may explain why lesions develop at some sites and not others.

description: We study the performance of state-of-the-art human keypoint detectors in the context of close proximity human-robot interaction. The detection in this scenario is specific in that only a subset of body parts such as hands and torso are in the field of view. In particular, (i) we survey existing datasets with human pose annotation from the perspective of close proximity images and prepare and make publicly available a new Human in Close Proximity (HiCP) dataset; (ii) we quantitatively and qualitatively compare state-of-the-art human whole-body 2D keypoint detection methods (OpenPose, MMPose, AlphaPose, Detectron2) on this dataset; (iii) since accurate detection of hands and fingers is critical in applications with handovers, we evaluate the performance of the MediaPipe hand detector; (iv) we deploy the algorithms on a humanoid robot with an RGB-D camera on its head and evaluate the performance in 3D human keypoint detection. A motion capture system is used as reference. The best performing whole-body keypoint detectors in close proximity were MMPose and AlphaPose, but both had difficulty with finger detection. Thus, we propose a combination of MMPose or AlphaPose for the body and MediaPipe for the hands in a single framework providing the most accurate and robust detection. We also analyse the failure modes of individual detectors -- for example, to what extent the absence of the head of the person in the image degrades performance. Finally, we demonstrate the framework in a scenario where a humanoid robot interacting with a person uses the detected 3D keypoints for whole-body avoidance maneuvers.

Here we investigate the system SrCo2V2O8, a realization of the weakly-coupled Ising-like XXZ antiferromagnetic chains, by terahertz spectroscopy with and without applied magnetic field. At low temperatures a series of excitations is observed, which split in a Zeeman-like fashion in an applied magnetic field. These magnetic excitations are identified as the theoretically predicted spinon-pair excitations. Using a one dimensional Schrödinger equation with a linear confinement potential imposed by weak interchain couplings, the hierarchy of the confined spinons can be fully described.

description: Dimerization of polycyclic aromatic hydrocarbons (PAHs) is an important, yet poorly understood, step in the on-surface synthesis of graphene (nanoribbon), soot formation, and growth of carbonaceous dust grains in the interstellar medium (ISM). The on-surface synthesis of graphene and the growth of carbonaceous dust grains in the ISM require the chemical dimerization in which chemical bonds are formed between PAH monomers. An accurate and cheap method of exploring structure rearrangements is needed to reveal the mechanism of chemical dimerization on surfaces. This work has investigated the chemical dimerization of two dehydrogenated PAHs (coronene and pentacene) on graphene via an evolutionary algorithm augmented by machine learning surrogate potentials and a set of customized structure operators. Different dimer structures on surfaces have been successfully located by our structure search methods. Their binding energies are within the experimental errors of temperature programmed desorption measurements. The mechanism of coronene dimer formation on graphene is further studied and discussed.

description: This paper presents a theoretical study on the ability of multi-rotor aerial vehicles (MRAVs) with tiltable propellers to achieve and sustain static hovering at different orientations. To analyze the ability of MRAVs with tiltable propellers to achieve static hovering, a novel linear map between the platform's control inputs and applied forces and moments is introduced. The relation between the introduced map and the platform's ability to hover at different orientations is developed. Correspondingly, the conditions for MRAVs with tiltable propellers to realize and sustain static hovering are detailed. A numerical metric is then introduced, which reflects the ability of MRAVs to sustain static hovering at different orientations. A subclass of MRAVs with tiltable propellers is defined as the Critically Statically Hoverable platforms (CSH), where CSH platforms are MRAVs that cannot sustain static hovering with fixed propellers, but can achieve static hovering with tilting propellers. Finally, extensive simulations are conducted to test and validate the above findings, and to demonstrate the effect of the proposed numerical metric on the platform's dynamics.

description: Monosilicides of 3d-metals frequently show a chiral magnetic ordering with the absolute configuration defined by the chirality of the crystal structure and the sign of the Dzyaloshinskii-Moriya interaction (DMI). Structural and magnetic chiralities are probed here for Fe$_{1-x}$Co$_x$Si series and their mutual relationship is found to be dependent on the chemical composition. The chirality of crystal structure was previously shown to be governed by crystal growth, and the value of the DMI is nearly the same for all monosilicides of Fe, Co and Mn. Our findings indicate that the sign of the DMI in Fe$_{1-x}$Co$_x$Si is controlled by the Co composition $x$, thus, opening a route towards controlled design of chiral spintronics devices.

description: Human keratinocytes grown in medium containing reduced calcium concentrations (0.07 mM) have been found to show altered morphology and decreased differentiation in comparison with cells grown in medium with physiologic calcium concentrations (1-2 mM). Since such alterations could be mediated by growth factors, we measured binding of [125I]epidermal growth factor (EGF). Neonatal keratinocytes were subcultured without feeder layers and grown to confluence in 1.1 mM calcium. Medium was changed and cells incubated for various periods in reduced calcium prior to binding assays. Scatchard plots of binding data showed a 5-fold increase in receptor number with no change in affinity (3 X 10(-9) M) after 4-24 h at 37 degrees C. Maximal binding occurred at 0.02-0.04 mM calcium and decreased sharply with increasing calcium concentrations. The increase could be prevented by calcium added soon after binding began to increase but was altered less after substantial elevation had occurred, although morphologic changes at reduced calcium concentrations were reversed within several hours. Substantial increases in binding of [125I]somatomedin C and [125I]concanavalin A were detected, but binding of [125I]pindalol, a beta-receptor ligand, was changed little. Keratinocytes at reduced calcium concentrations responded to added EGF by decreasing surface EGF receptors briskly in a time- and temperature-dependent fashion. The data suggest that keratinocytes show enhanced binding of EGF and some other cell surface ligands under conditions in which differentiation is retarded.

description: Theoretically, misalignment between the magnetic field and rotational axis in a dense core is considered to be dynamically important in the star formation process, however, extent of this influence remains observationally unclear. For a sample of 32 Class 0 and I protostars in the Perseus Molecular Cloud, we analyzed gas motions using C$^{18}$O data from the SMA MASSES survey and the magnetic field structures using 850 $μ$m polarimetric data from the JCMT BISTRO-1 survey and archive. We do not find any significant correlation between the velocity gradients in the C$^{18}$O emission in the protostellar envelopes at a 1,000 au scale and the misalignment between the outflows and magnetic field orientations in the dense cores at a 4,000 au scale, and there is also no correlation between the velocity gradients and the angular dispersions of the magnetic fields. However, a significant dependence on the misalignment angles emerges after we normalize the rotational motion by the infalling motion, where the ratios increase from $\lesssim1$ to $\gtrsim1$ with increasing misalignment angles. This suggests that the misalignment could prompt angular momentum transportation to the envelope scale but is not a dominant factor in determining the envelope rotation, and other parameters, like mass accretion in protostellar sources, also play an important role. These results remain valid after taking into account projection effects. The comparison between our estimated angular momentum in the protostellar envelopes and the sizes of the known protostellar disks suggests that significant angular momentum is likely lost between radii of $\sim$1,000-100 au in protostellar envelopes.

description: Taking advantage of biocompatible chitosan (CS), halloysite (Hal) and ionic liquid (IL), a triple hybrid system, Hal-CS-SFIL was designed and prepared via covalent bonding of Cl-functionalized Hal and CS-SFIL. The hybrid system was successfully utilized as a heterogeneous catalyst support for immobilizing Pd nanoparticles. The resulting hybrid catalyst, Pd@Hal-CS-SFIL was used as a heterogeneous catalyst for catalyzing Sonogashira reaction under mild reaction condition. The results showed that this catalyst was efficient. Studying the recyclability of the catalyst confirmed that the catalyst could be recycled for seven reaction runs with slight loss of the catalytic activity and Pd leaching. The role of each hybrid component in the catalysis was confirmed by comparing the catalytic activity of Pd@Hal, Pd@CS, Pd@Hal-CS and Pd@Hal-CS-SFIL. Moreover, the synergism between the components was established by observing the superior catalytic activity of the catalyst with those of Pd@Hal-CS + SFIL, Pd@CS-SFIL+Hal and Pd@Hal + CS-SFIL.

description: We estimate the size and distribution of the parent populations for the 6 largest (at least 20 stars in the Solar neighborhood) chemical groups identified in the Chemical Tagging experiment by Mitschang et al.~2014. Stars in the abundance groups tend to lie near a boundary in angular momentum versus eccentricity space where the probability is highest for a star to be found in the Solar neighborhood and where orbits have apocenter approximately equal to the Sun's galactocentric radius. Assuming that the parent populations are uniformly distributed at all azimuthal angles in the Galaxy, we estimate that the parent populations of these abundance groups contain at least 200,000 members. The spread in angular momentum of the groups implies that the assumption of a uniform azimuthal distribution only fails for the two youngest groups and only for the highest angular momentum stars in them. The parent populations of three thin disk groups have narrow angular momentum distributions, but tails in the eccentricity and angular momentum distributions suggest that only a small fraction of stars have migrated and increased in eccentricity. In contrast, the parent populations of the thick disk groups exhibit both wide angular momentum and eccentricity distributions implying that both heating and radial migration has taken place.

description: A range of quantum field theoretical phenomena driven by external magnetic fields and their applications in relativistic systems and quasirelativistic condensed matter ones, such as graphene and Dirac/Weyl semimetals, are reviewed. We start by introducing the underlying physics of the magnetic catalysis. The dimensional reduction of the low-energy dynamics of relativistic fermions in an external magnetic field is explained and its role in catalyzing spontaneous symmetry breaking is emphasized. The general theoretical consideration is supplemented by the analysis of the magnetic catalysis in quantum electrodynamics, chromodynamics and quasirelativistic models relevant for condensed matter physics. By generalizing the ideas of the magnetic catalysis to the case of nonzero density and temperature, we argue that other interesting phenomena take place. The chiral magnetic and chiral separation effects are perhaps the most interesting among them. In addition to the general discussion of the physics underlying chiral magnetic and separation effects, we also review their possible phenomenological implications in heavy-ion collisions and compact stars. We also discuss the application of the magnetic catalysis ideas for the description of the quantum Hall effect in monolayer and bilayer graphene, and conclude that the generalized magnetic catalysis, including both the magnetic catalysis condensates and the quantum Hall ferromagnetic ones, lies at the basis of this phenomenon. We also consider how an external magnetic field affects the underlying physics in a class of three-dimensional quasirelativistic condensed matter systems, Dirac semimetals. While at sufficiently low temperatures and zero density of charge carriers, such semimetals are expected to reveal the regime of the magnetic catalysis, the regime of Weyl semimetals with chiral asymmetry is realized at nonzero density...
