description: Since the first experimental evidences of active conductances in dendrites, most neurons have been shown to exhibit dendritic excitability through the expression of a variety of voltage-gated ion channels. However, despite experimental and theoretical efforts undertaken in the last decades, the role of this excitability for some kind of dendritic computation has remained elusive. Here we show that, owing to very general properties of excitable media, the average output of a model of active dendritic trees is a highly non-linear function of their afferent rate, attaining extremely large dynamic ranges (above 50 dB). Moreover, the model yields double-sigmoid response functions as experimentally observed in retinal ganglion cells. We claim that enhancement of dynamic range is the primary functional role of active dendritic conductances. We predict that neurons with larger dendritic trees should have larger dynamic range and that blocking of active conductances should lead to a decrease of dynamic range.

description: Decompression sickness (DCS) describes a condition characterized by a variety of symptoms resulting from exposure to low barometric pressures that cause inert gases (mainly nitrogen), normally dissolved in body fluids and tissues, to come out of physical solution and form bubbles. DCS can occur during exposure to altitude (altitude DCS) or during ascent from depth (mining or diving). The first documented cases of DCS (Caisson Disease) were reported in 1841 by a mining engineer who observed the occurrence of pain and muscle cramps among coal miners exposed to air-pressurized mine shafts designed to keep water out. The first description of a case resulting from diving activities while wearing a pressurized hard hat was reported in 1869.

description: This article provides a detailed study of Korean diasporas and enclaves abroad, including their adaptation to the host country. Adaptation of South Koreans to the host country in various emigrant communities has its own characteristics, which are determined by both historical and sociocultural factors. A detailed analysis of the adaptation process of Korean communities living in Uzbekistan, the USA, China, Japan, Russia and Kazakhstan was conducted and recommendations were developed to improve the conditions for adaptation of South Koreans and other ethnic groups abroad, which contributes to the creation of a more open and tolerant world community.
BREVE STORIA DELLA CLASSE DI CONCORSO A23 - LINGUA ITALIANA PER DISCENTI DI LINGUA STRANIERA

description: Nel corso degli ultimi trent’anni la crescente presenza di studentesse e studenti neoarrivati, immigrati e figli di genitori immigrati ha fortemente influenzato la società italiana e ha impegnato il sistema scolastico al fine di favorire la loro integrazione linguistica e sociale. Nonostante nel corso degli ultimi decenni il numero delle studentesse e degli studenti alloglotti sia aumentato sensibilmente, solo a partire dall’anno scolastico 2017/2018 è stata introdotta la figura del docente di Lingua italiana per discenti di lingua straniera. L’assenza di docenti esperti e competenti nell’ambito della didattica dell’italiano L2, infatti, ha a lungo caratterizzato gli interventi di integrazione linguistica rivolti agli studenti alloglotti. Per questo motivo l’istituzionalizzazione della classe di concorso A23-Lingua italiana per discenti di lingua straniera è un momento fondamentale per il riconoscimento istituzionale dell’insegnamento dell’italiano L2 nella scuola pubblica. Il presente contributo si propone di ripercorrere le diverse tappe che hanno portato al primo inserimento dei docenti della classe di concorso A23 e mette in luce i problemi e le criticità emerse durante i primi tre anni scolastici di servizio. A short history of the competition class A23 - Italian language for foreign language learners Over the last thirty years, the arrival of a large number of foreign people has had a considerable impact on Italian society. Consequently, the national school system has been greatly affected, seen in daily life at Italian schools. Since the 2017/2018 school year, for the first time, teachers who had successfully completed a structured course on teaching Italian as a second language were included in Italian public school staff. For a long time, Italian public schools did not have highly qualified staff able to face problems linked to learning Italian as a second language. For this reason, the recruitment of A23 teachers can be considered key. This paper focuses on the major steps that led to the inclusion of professionals qualified to teach Lingua italiana per discenti di lingua straniera. in Italian public schools.

We take the limit $N, L \to \infty$ while keeping the density $ρ= N / L^3$ fixed and small. We prove a new lower bound for its ground state energy per particle $$\frac{E(N, Λ)}{N} \geq 4 πa ρ[ 1 - O(ρ^{1/3} |\log ρ|^3) ],$$ as $ρ\to 0$, where $a$ is the scattering length of $V$.

description: Chains of metallic nanoparticles sustain strongly confined surface plasmons with relatively low dielectric losses. To exploit these properties in applications, such as waveguides, the fabrication of long chains of low disorder and a thorough understanding of the plasmon-mode properties, such as dispersion relations, are indispensable. Here, we use a wrinkled template for directed self-assembly to assemble chains of gold nanoparticles. With this up-scalable method, chain lengths from two particles (140 nm) to 20 particles (1500 nm) and beyond can be fabricated. Electron energy-loss spectroscopy supported by boundary element simulations, finite-difference time-domain, and a simplified dipole coupling model reveal the evolution of a band of plasmonic waveguide modes from degenerated single-particle modes in detail. In striking difference from plasmonic rod-like structures, the plasmon band is confined in excitation energy, which allows light manipulations below the diffraction limit. The non-degenerated surface plasmon modes show suppressed radiative losses for efficient energy propagation over a distance of 1500 nm. © 2019 American Chemical Society.

description: We present a simple scenario for gauge mediated supersymmetry breaking where the messengers are also the fields that generate neutrino masses. We show that the simplest such scenario corresponds to the case where neutrino masses are generated through the Type I and Type III seesaw mechanisms. The entire supersymmetric spectrum and Higgs masses are calculable from only four input parameters. Since the electroweak symmetry is broken through a doubly radiative mechanism, meaning a nearly zero B-term at the messenger scale which runs down to acceptable values, one obtains quite a constrained spectrum for the supersymmetric particles whose properties we describe. We refer to this mechanism as "nu-GMSB".

description: Efficient supercontinuum generation demands for fine-tuning of the dispersion of the underlying waveguide. Resonances introduced into waveguide systems can substantially improve nonlinear dynamics in ultrafast supercontinuum generation via modal hybridization and formation of avoided crossings. Using the example of exposed core fibers functionalized by nanofilms with sub-nanometer precision both zero-dispersion and dispersive wave emission wavelengths are shifted by 227 and 300 nm, respectively, at tuning slopes higher than 20 nm/nm. The presented concept relies on dispersion management via induced resonances and can be straightforwardly extended to other deposition techniques and film geometries such as multilayers or 2D materials. It allows for the creation of unique dispersion landscapes, thus tailoring nonlinear dynamics and emission wavelengths and for making otherwise unsuitable waveguides relevant for ultrafast nonlinear photonics. © 2020 The Authors.

description: This is the second of a series of papers on the special relativistic classical statistical mechanics. Employing the general theory developed in the first paper we rigorously derive the relativistic Vlasov, Landau and Boltzmann equation. The latter two advocate the J{ü}ttner distribution as the equilibrium distribution. We thus, at the full microscopic level, provide a support for the recent numerical finding [D. Cubero {\it et. al.}, Phys. Rev. Lett. \textbf{99}, 170601 (2007)] of the special relativistic generalization of the Maxwell-Boltzmann distribution. Furthermore, the present theory allows us to rigorously calculate various correlation functions at the relativistic many-body equilibrium. Therefore, the relativistic many-body equilibrium conjecture of Hakim is justified.

description: We construct the p-adic zeta function for a one-dimensional (as a p-adic Lie extension) non-commutative p-extension of a totally real number field such that the finite part of its Galois group is a pgroup with exponent p. We first calculate the Whitehead groups of the Iwasawa algebra and its canonical Ore localisation by using Oliver-Taylor's theory upon integral logarithms. This calculation reduces the existence of the non-commutative p-adic zeta function to certain congruence conditions among abelian p-adic zeta pseudomeasures. Then we finally verify these congruences by using Deligne-Ribet's theory and certain inductive technique. As an application we shall prove a special case of (the p-part of) the non-commutative equivariant Tamagawa number conjecture for critical Tate motives. The main results of this paper give generalisation of those of the preceding paper of the author.

A study on security level management model for information system
Creators: name: Kim, TH
Publisher: name: University Of Tasmania
Year: 2023

description: The attempts to protect information and Information System (IS) from the threats are progressing variously and systematically, and the necessity to build security countermeasures by considering the characteristics of IS is gathering strength. In fact, to satisfy the proposition of information security, we don't have to invest excessive budget. Needless to say, it is important to protect information and IS, but it is not desirable to build uniform security countermeasures regardless of degree of importance. Depending on the purpose of building or operation, IS may have different degree of importance, meaning an IS may have higher degree of importance than other IS. Systems in same office can even have different degree of importance. In other words, some systems should be protected from the attack, even though some systems can be compromised from the same attack. In agreement with the degree of importance of IS, the strength of security countermeasure should be changed. For important systems, stronger security countermeasures should be selected, and stronger verification processes should be executed properly. As we can reduce unnecessary budget for IS which has a lower degree of importance, we can increase investment to IS which has higher degree of importance with the budget saved from other IS. Therefore, the most important factor is the decision of degree of importance of IS. From now on, this degree of importance will be called required security level or security level briefly. Depending on the selected security level, strength of security countermeasures should be decided. Security countermeasures can be formed after deciding the security level. In this thesis, after analysing previous research results, the author proposes some essential elements for security level definition and management of IS. After classifying, proper level was granted to threats and assets, and weights were assigned to each level. By summating these weights, the security level of an IS can be decided. After deciding the security level, basic technical and non-technical requirements for security level management are proposed in detail. Some items needed to ensure basic security state of IS are listed in this requirements. After this, level requirements to ensure security level required for each IS are proposed in detail. These level requirements should be applied differently for both technical and non-technical parts. Level requirements are designed by using step-model for technical areas, and continuous-model for non-technical areas.
Effect of accretion on primordial black holes in Brans-Dicke theory

description: We consider the effect of accretion of radiation in the early universe on primordial black holes in Brans-Dicke theory. The rate of growth of a primordial black hole due to accretion of radiation in Brans-Dicke theory is considerably smaller than the rate of growth of the cosmological horizon, thus making available sufficient radiation density for the black hole to accrete causally. We show that accretion of radiation by Brans-Dicke black holes overrides the effect of Hawking evaporation during the radiation dominated era. The subsequent evaporation of the black holes in later eras is further modified due to the variable gravitational ``constant'', and they could survive up to longer times compared to the case of standard cosmology. We estimate the impact of accretion on modification of the constraint on their initial mass fraction obtained from the $γ$-ray background limit from presently evaporating primordial black holes.

description: Laser-induced backside wet etching (LIBWE) allows the high-quality etching of transparent materials for micro- and nanopatterning. Recent own results of LIBWE with hydrocarbon and metallic absorbers (H- and M-LIBWE) are summarized and compared with selected results of other groups regarding the etching process and the etched surface. Significant results on the impact of the liquid absorber, the material and the wavelength, and the pulse length of the laser to the etching are selected for this comparison. The etching of submicron-sized periodic structures in sapphire and fused silica with interference techniques and the selection of the preferred method in dependence on the material and the processing goal discussed. The experimental results are discussed on a thermal model considering both interface and volume absorption of the laser beam. These results have the conclusion that the etching at M-LIBWE is mainly due to material melting and evaporation whereas at H-LIBWE, a modified near-surface region with a very high absorption is ablated.
The potential of biomimetic cabbage leaves in preventing biofouling of Escherichia coli and Listeria monocytogenes
Creators: name: Mergulhão, Filipe
Publisher: name: Zenodo
Year: 2023
Subjects: biomimetic surfaces; biofouling: food industry

description: Food contact surfaces are usually colonized by microorganisms, even following cleaning and disinfection. They can grow as biofilms, which are contamination sources of finished products, reducing their shelf life and causing foodborne diseases. One way to reduce fouling is to design naturally cleaning surfaces based on biomimetic designs. Four self-cleaning leaves (Tenderheart cabbage, Cauliflower, White cabbage, and Leek) were analysed for their surface properties. The leaves and artificial replicates were subjected to attachment, adhesion and retention assays using Escherichia coli and Listeria monocytogenes. All the surfaces were non-wettable (water contact angles higher than 100 °), with the biomimetic Tenderheart cabbage demonstrating the most non-wettable surface. However, when the hydrophobicity of the surfaces was determined, the White cabbage was demonstrated to be the most hydrophobic surface (ΔGiwi ≈ - 88 mJ m-2). The natural White cabbage also presented the lowest roughness values (Sq = 3.5 µm), although the corresponding replica was the roughest of the fabricated surfaces (Sq = 5.3 µm). L. monocytogenes were generally bound to the surfaces in lower numbers than E. coli. The Leek leaves retained more E. coli cells than the other cabbages, and the Tenderheart cabbage promoted E. coli attachment and adhesion. Therefore, for E. coli, surface hydrophobicity was not a controlling factor in the bacterial retention, attachment and adhesion. The Leek leaves retained more culturable L. monocytogenes cells than the other cabbage leaves, suggesting a correlation between surface hydrophobicity and the retention and attachment of L. monocytogenes. Overall, the biomimetic surfaces were more efficient at avoiding bacterial retention than natural leaves.
On the Fundamental Line of Galactic and Extragalactic Globular Clusters

description: In a previous paper we found that the Globular Clusters of our Galaxy lie around a line in the log(Re), SBe, log(sigma) parameter space, with a moderate degree of scatter and remarkable axi-symmetry. This implies the existence of a purely photometric scaling law obtained by projecting such a line onto the log(Re), SBe plane. Such photometric quantities are readily available for large samples of clusters, as opposed to stellar velocity dispersion data. We study a sample of 129 Galactic and extragalactic clusters on such photometric plane in the V-band. We look for a linear relation between SBe and log(Re) and study how the scatter around it is influenced by age and dynamical environment. We interpret our results as a test on the evolutionary versus primordial origin of the Fundamental Line. We perform a detailed analysis of surface brightness profiles, which allows us to present a catalogue of structural properties, without relying on a given dynamical model. We find a linear relation between SBe and log(Re), in the form SBe = (5.25 +- 0.44) log(Re) + (15.58 +- 0.28), where SBe is measured in mag/arcsec^2 and Re in parsec. Both young and old clusters lie on the scaling law, with a scatter of approximately 1 mag in SBe. However, young clusters display more scatter and a clear trend of such scatter with age, which old clusters do not. Such trend becomes tighter if cluster age is measured in units of the cluster half-light relaxation time. Two-body relaxation therefore plays a major role, together with passive stellar population evolution, in shaping the relation between SBe, log(Re), and cluster age. We argue that the log(Re)-SBe relation and hence the Fundamental Line scaling law is not primordially set at cluster formation, but rather is the result of combined stellar evolution and collisional dynamical evolution.

description: Under the assumption that the approximating function $ψ$ is monotonic, the classical Khintchine-Groshev theorem provides an elegant probabilistic criterion for the Lebesgue measure of the set of $ψ$-approximable matrices in $\R^{mn}$. The famous Duffin-Schaeffer counterexample shows that the monotonicity assumption on $ψ$ is absolutely necessary when $m=n=1$. On the other hand, it is known that monotonicity is not necessary when $n > 2$ (Sprindzuk) or when $n=1$ and $m>1$ (Gallagher). Surprisingly, when $n=2$ the situation is unresolved. We deal with this remaining case and thereby remove all unnecessary conditions from the classical Khintchine-Groshev theorem. This settles a multi-dimensional analogue of Catlin's Conjecture.

Our results will show that certain phenomena known to hold for the hyperfinite factor of type 11₁ also hold for type III factors. Let M and N be subalgebras of the factor α . We call M and N equivalent if M is the image of N by some automorphism of α . Let N(M) denote the subalgebra of α generated by all those unitary operators in α which induce automorphisms of M, and let N²(M), N³(M),... be defined in the obvious inductive fashion. Following J. Dixmier and S. Anastasio, we call a MA subalgebra M of α singular if N(M) = M, regular if N(M) = α, semi-regular if N(M) is a factor distinct from α, and m-semi-regular (m ≥ 2) if N(M),. . .N(m-1)(M) are not factors but N(m)(M) is a factor. The MA subalgebras of the hyperfinite 11₁ factor β have received much attention in the literature, in the papers of J. Dixmier, L. Pukanszky, Sister R. J. Tauer, and S. Anastasio. It is known that β contains a MA subalgebra of each type. Further, β contains pairwise inequivalent sequences of singular, semi-regular, 2-semi-regular, and 3-semi-regular MA subalgebras. The only hitherto known example of a MA subalgebra in a type III factor is regular. In 1956 Pukanszky gave a general method for constructing MA subalgebras in a class of (probably non-hyperfinite) type III factors. Because of an error in a calculation, the types of these subalgebras is not known. The main result of this thesis is the construction, in each of the uncountably many mutually non-isomorphic hyperfinite type III factors of R. Powers, of: (i) a semi-regular MA subalgebra (ii) two sequences of mutually inequivalent 2-semi-regular MA subalgebras 1 (iii) two sequences of mutually inequivalent 3-semi-regular MA subalgebras. Let α denote one of these type III factors and let β denote the hyperfinite 11₁ factor. Roughly speaking, whenever a non-singular MA subalgebra of β is constructed by means of group operator algebras, our method will produce a MA subalgebra of α of the same type. H. Araki and J. Woods have shown that α ⊗ β ≅ α, and it is therefore only necessary to construct MA subalgebras of α ⊗ β of the desired type. We obtain MA subalgebras of α ⊗ β by tensoring a MA subalgebra in α with one in β. In order to determine the type of such a MA subalgebra, we realize β as a constructible algebra and then regard α ⊗ β as a constructible algebra; this allows us to consider operators in α ⊗ β as functions from a group into an abelian von Neumann algebra. As a corollary to our calculations, we are able to construct mutually inequivalent sequences of 2-semi-regular and 3-semi-regular MA subalgebras of the hyperfinite 11₁ factor which differ from those of Anastasio.

New X-ray observations of the Geminga pulsar wind nebula

description: Previous observations of the middle-aged pulsar Geminga with XMM-Newton and Chandra have shown an unusual pulsar wind nebula (PWN), with a 20" long central (axial) tail directed opposite to the pulsar's proper motion and two 2' long, bent lateral (outer) tails. Here we report on a deeper (78 ks) Chandra observation and a few additional XMM-Newton observations of the Geminga PWN. The new Chandra observation has shown that the axial tail, which includes up to three brighter blobs, extends at least 50" (i.e., 0.06 d_{250} pc) from the pulsar. It also allowed us to image the patchy outer tails and the emission in the immediate vicinity of the pulsar with high resolution. The PWN luminosity, L_{0.3-8 keV} ~ 3\times 10^{29} d_{250}^2 erg/s, is lower than the pulsar's magnetospheric luminosity by a factor of 10. The spectra of the PWN elements are rather hard (photon index ~ 1). Comparing the two Chandra images, we found evidence of PWN variability, including possible motion of the blobs along the axial tail. The X-ray PWN is the synchrotron radiation from relativistic particles of the pulsar wind; its morphology is connected with the supersonic motion of Geminga. We speculate that the outer tails are either (1) a sky projection of the limb-brightened boundary of a shell formed in the region of contact discontinuity, where the wind bulk flow is decelerated by shear instability, or (2) polar outflows from the pulsar bent by the ram pressure from the ISM. In the former case, the axial tail may be a jet emanating along the pulsar's spin axis, perhaps aligned with the direction of motion. In the latter case, the axial tail may be the shocked pulsar wind collimated by the ram pressure.

description: Heterostructures comprising silicon, molybdenum disulfide (MoS2), and graphene are investigated with respect to the vertical current conduction mechanism. The measured current-voltage (I-V) characteristics exhibit temperature-dependent asymmetric current, indicating thermally activated charge carrier transport. The data are compared and fitted to a current transport model that confirms thermionic emission as the responsible transport mechanism across devices. Theoretical calculations in combination with the experimental data suggest that the heterojunction barrier from Si to MoS2 is linearly temperature-dependent for T = 200-300 K with a positive temperature coefficient. The temperature dependence may be attributed to a change in band gap difference between Si and MoS2, strain at the Si/MoS2 interface, or different electron effective masses in Si and MoS2, leading to a possible entropy change stemming from variation in density of states as electrons move from Si to MoS2. The low barrier formed between Si and MoS2 and the resultant thermionic emission demonstrated here make the present devices potential candidates as the emitter diode of graphene base hot electron transistors for future high-speed electronics.

description: Tidal friction is thought to be important in determining the long-term spin-orbit evolution of short-period extrasolar planetary systems. Using a simple model of the orbit-averaged effects of tidal friction Eggleton, Kiseleva & Hut (1998), we analyse the effects of the inclusion of stellar magnetic braking on the evolution of such systems. A phase-plane analysis of a simplified system of equations, including only the stellar tide together with a model of the braking torque proposed by Verbunt & Zwaan (1981), is presented. The inclusion of stellar magnetic braking is found to be extremely important in determining the secular evolution of such systems, and its neglect results in a very different orbital history. We then show the results of numerical integrations of the full tidal evolution equations, using the misaligned spin and orbit of the XO-3 system as an example, to study the accuracy of simple timescale estimates of tidal evolution. We find that it is essential to consider coupled evolution of the orbit and the stellar spin in order to model the behaviour accurately. In addition, we find that for typical Hot Jupiters the stellar spin-orbit alignment timescale is of the same order as the inspiral time, which tells us that if a planet is observed to be aligned, then it probably formed coplanar. This reinforces the importance of Rossiter-McLaughlin effect observations in determining the degree of spin-orbit alignment in transiting systems.

Gamma-ray Constraints on Dark Matter Annihilation into Charged Particles

description: Dark matter annihilation into charged particles is necessarily accompanied by gamma rays, produced via radiative corrections. Internal bremsstrahlung from the final state particles can produce hard gamma rays up to the dark matter mass, with an approximately model-independent spectrum. Focusing on annihilation into electrons, we compute robust upper bounds on the dark matter self annihilation cross section $_{e^+e^-}$ using gamma ray data from the Milky Way spanning a wide range of energies, $\sim10^{-3} - 10^4$ GeV. We also compute corresponding bounds for the other charged leptons. We make conservative assumptions about the astrophysical inputs, and demonstrate how our derived bounds would be strengthened if stronger assumptions about these inputs are adopted. The fraction of hard gamma rays near the endpoint accompanying annihilation to $e^+e^-$ is only a factor of $\alt 10^2$ lower than for annihilation directly to monoenergetic gamma rays. The bound on $_{e^+e^-}$ is thus weaker than that for $_{γγ}$ by this same factor. The upper bounds on the annihilation cross sections to charged leptons are compared with an upper bound on the {\it total} annihilation cross section defined by neutrinos.

Purely electric spin pumping in one-dimension

description: We show theoretically that a simple one dimensional system (such as metallic wire) can display quantum spin pumping possibly without pushing any charge. It is achieved by applying two slowly varying orthogonal gate electric fields on different sections of the wire, thereby generating local spin-orbit (Rashba) terms such that unitary transformations at different places do not commute. This construction is a unique manifestation of a spin-orbit observable effect in purely one dimensional systems with potentials respecting time-reversal symmetry.

Witnessing the active assembly phase of massive galaxies since z = 1

description: We present an analysis of ~60 000 massive (stellar mass M_star > 10^{11} M_sun) galaxies out to z = 1 drawn from 55.2 deg2 of the United Kingdom Infrared Telescope (UKIRT) Infrared Deep Sky Survey (UKIDSS) and the Sloan Digital Sky Survey (SDSS) II Supernova Survey. This is by far the largest survey of massive galaxies with robust mass estimates, based on infrared (K-band) photometry, reaching to the Universe at about half its present age. We find that the most massive (M_star > 10^{11.5} M_sun) galaxies have experienced rapid growth in number since z = 1, while the number densities of the less massive systems show rather mild evolution. Such a hierarchical trend of evolution is consistent with the predictions of the current semi-analytic galaxy formation model based on Lambda CDM theory. While the majority of massive galaxies are red-sequence populations, we find that a considerable fraction of galaxies are blue star-forming galaxies. The blue fraction is smaller in more massive systems and decreases toward the local Universe, leaving the red, most massive galaxies at low redshifts, which would support the idea of active 'bottom-up' formation of these populations during 0 < z < 1.
