description: Dynamic lower airway obstruction is the primary component of canine bronchomalacia, but the ventilatory function remains underinvestigated. This prospective study analyzed tidal breathing characteristics in 28 dogs, comprising 14 with severe bronchomalacia diagnosed by bronchoscopy versus 14 without respiratory disease. Spirometry was conducted in all dogs. Bronchoscopy with bronchoalveolar lavage or brush under anesthesia was performed in 14 dogs with cough and expiratory effort. Severe bronchomalacia was defined by the severity of collapse and total number of bronchi affected. Ventilatory characteristics were compared between groups. Results revealed that dogs with severe bronchomalacia had lower minute volume (218 vs 338 mL/kg, p = .039) and greater expiratory-to-inspiratory time ratio (1.55 vs 1.35, p = .01) compared to control dogs. The tidal breathing pattern of dogs with bronchomalacia was different from that of normal dogs, and the pattern differed from the concave or flat expiratory curves typical of lower airway obstruction. Compared to control dogs, dogs with severe bronchomalacia had a significantly prolonged low-flow expiratory phase (p < .001) on the flow-time plot and a more exponential shape of the expiratory curve (p < .001) on the volume-time plot. Flow-time index ExpLF/Te (>0.14) and volume-time index Vt-AUCexp (≤31%) had a high ROC-AUC (1.00, 95% confidence interval 0.88 to 1.00) in predicting severe bronchomalacia. In conclusion, the tidal breathing pattern identified here indicates abnormal and complicated ventilatory mechanics in dogs with severe bronchomalacia. The role of this pulmonary functional phenotype should be investigated for disease progression and therapeutic monitoring in canine bronchomalacia.

description: The postmortem examination can be used as a means of quality control for clinical diagnoses. A retrospective study on 300 dogs and cats that had been admitted to a small animal intensive care unit was performed comparing the clinical and postmortem findings, using the Modified Goldman criteria. All patient files were reevaluated for clinical diagnoses and all postmortem material was reevaluated for pathological diagnoses. After this, the Modified Goldman criteria were applied to score the discrepancies between them, and factors associated with the occurrence of an undiagnosed major unexpected finding were analyzed. The postmortem examination revealed additional findings in 65% of the cases. Major discrepancies, defined as those affecting treatment and possibly outcome of the patient, were present in 21.3% of the cases. The most frequently missed diagnoses detected at necropsy were pneumonia of various etiologies, meningitis/meningoencephalitis, myocarditis and generalized vasculitis. A shorter ICU stay was associated with increased odds of a major discrepancy. Conditions affecting the urinary or gastrointestinal system were negatively associated with major discrepancy.

description: The inadvertent stealing of private/sensitive information using Knowledge Distillation (KD) has been getting significant attention recently and has guided subsequent defense efforts considering its critical nature. Recent work Nasty Teacher proposed to develop teachers which can not be distilled or imitated by models attacking it. However, the promise of confidentiality offered by a nasty teacher is not well studied, and as a further step to strengthen against such loopholes, we attempt to bypass its defense and steal (or extract) information in its presence successfully. Specifically, we analyze Nasty Teacher from two different directions and subsequently leverage them carefully to develop simple yet efficient methodologies, named as HTC and SCM, which increase the learning from Nasty Teacher by upto 68.63% on standard datasets. Additionally, we also explore an improvised defense method based on our insights of stealing. Our detailed set of experiments and ablations on diverse models/settings demonstrate the efficacy of our approach.

description: We reported an outbreak of wild rabies in Potus flavus (choznas), a carnivorous mammal associated with insectivorous bats in Kosñipata, Cusco, Peru, from February 2021 to October 2022. Eight human exposures were reported, with aggressive attacks resulting in injuries. The outbreak prompted a public health response and raised concerns about zoonotic diseases due to habitat fragmentation and urbanization. The study involved antigenic and genetic characterization of the virus in the affected animals, revealing similarities with variants in non-hematophagous bats. This outbreak marked the first time rabies had been reported in choznas in the region, highlighting the need for early intervention programs and wildlife protection. Pre-exposure rabies vaccinations were administered to residents, and community surveillance was established to control the outbreak. The study emphasizes the importance of continuous surveillance and education to prevent rabies transmission from choznas to humans and other animals, as their role as potential secondary transmitters of the virus warrants further investigation.

description: It is shown that Majorana fermions trapped in three vortices in a p-wave superfluid form a qubit in a topological quantum computing (TQC). Several similar ideas have already been proposed: Ivanov [Phys. Rev. Lett. {\bf 86}, 268 (2001)] and Zhang {\it et al.} [Phys. Rev. Lett. {\bf 99}, 220502 (2007)] have proposed schemes in which a qubit is implemented with two and four Majorana fermions, respectively, where a qubit operation is performed by exchanging the positions of Majorana fermions. The set of gates thus obtained is a discrete subset of the relevant unitary group. We propose, in this paper, a new scheme, where three Majorana fermions form a qubit. We show that continuous 1-qubit gate operations are possible by exchanging the positions of Majorana fermions complemented with dynamical phase change. 2-qubit gates are realized through the use of the coupling between Majorana fermions of different qubits.

description: We calculate the lowest-order corrections to the static potential for both the generalized Born-Infeld Electrodynamics and an Euler-Heisenberg-like model, in the presence of a constant external magnetic field. Our analysis is carried out within the framework of the gauge-invariant but path-dependent variables formalism. The calculation reveals a long-range correction ($ {\raise0.7ex\hbox{$1$} \mathord{\left/ {\vphantom {1 {r^5}}}\right.\kern-\nulldelimiterspace} \lower0.7ex\hbox{${r^5}$}}$-type) to the Coulomb potential for the generalized Born-Infeld Electrodynamics. Interestingly enough, in the Euler-Heisenberg-like model, the static potential remains Coulombian. Therefore, contrary to popular belief, the quantized truncated action and the truncated quantized action do not commute at all.

description: We consider the so-called one-dimensional forest fire process. At each site of $\mathbb{Z}$, a tree appears at rate $1$. At each site of $\mathbb{Z}$, a fire starts at rate $λ>0$, immediately destroying the whole corresponding connected component of trees. We show that when $λ$ is made to tend to $0$ with an appropriate normalization, the forest fire process tends to a uniquely defined process, the dynamics of which we precisely describe. The normalization consists of accelerating time by a factor $\log(1/λ)$ and of compressing space by a factor $λ\log(1/λ)$. The limit process is quite simple: it can be built using a graphical construction and can be perfectly simulated. Finally, we derive some asymptotic estimates (when $λ\to0$) for the cluster-size distribution of the forest fire process.

description: Viral diseases jeopardize the health of wildlife in Chile. However, this country lacks health surveillance programs that allow for defining preventive measures to tackle such diseases. The objective of this study was to determine the occurrence and the genetic diversity of pestivirus, herpesvirus and adenovirus in pudus from Chile. Blood samples from wild (n=34) and captive (n=32) pudus were collected between 2011 and 2019 and analyzed through consensus PCR. All the samples were negative to pestivirus and adenovirus. Herpesvirus was confirmed in four captive, and one wild pudu. All four zoo animals share the same sequence for both polymerase and glycoprotein genes. Both sequences share a 100% identity with caprine herpesvirus-2, classifying them in the same cluster as the Macavirus group. In turn, novel sequences of the polymerase and glycoprotein B genes were obtained from the wild pudu. Our study reports the first evidence of CpHV-2 infection in Chile and South American ungulate populations. Further research will be necessary to assess the pathogenicity of CpHV-2 in this species. It is also urgently recommended that molecular, serological and pathological screening should be conducted in Chilean wild and captive pudus to understand the impact of the herpesvirus on their populations.

description: Carnivore chaphamaparvovirus-1 (CaChPV-1) is a parvovirus identified in dogs and association of infection with diarrhea is controversial. Information on whether tissue tropism persists is lacking. To determine the disease association of CaChPV-1 in dogs with diarrhea and to investigate viral tropism and genetic diversity. CaChPV-1 infection was investigated in five recently deceased puppies and designed a retrospective study to determine whether the presence of CaChPV-1 is associated with diarrhea. The retrospective study was conducted in 137 intestinal tissue samples and 168 fecal samples obtained from 305 dogs. CaChPV-1 tissue localization was determined using in situ hybridization, and CaChPV-1 complete genomes obtained from dead puppies and retrospective study were sequenced and analyzed. CaChPV-1 was detected in 6.56% (20/305) of tested dogs, including 14 diarrheic- and 6 non-diarrheic dogs, and was significant in puppies with diarrhea (p = 0.048). Among the CaChPV-1-positive diarrheic dogs, one sample was obtained from intestinal tissue and 13 samples were fecal samples. However, six CaChPV-1 positive non-diarrheic dogs were based on fecal samples but not on intestinal tissue. Within the age range, the presence of CaChPV-1 was significant in puppies (p < 0.00001) and was mainly localized in the stromal and endothelial cells of intestinal villi and pulmonary alveoli. Phylogenetic analysis indicated genetic diversity of CaChPV-1 Thai strains that were mostly clustered within the sequences found in China. Although definitive pathogenesis of CaChPV-1 remains undetermined, this study provides evidence supporting that CaChPV-1 localizes in canine cells and could play a potential role as an enteric pathogen.

On anisotropic Gauss-Bonnet cosmologies in (n+1) dimensions, governed by an n-dimensional Finslerian 4-metric

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: The (n +1)-dimensional Einstein-Gauss-Bonnet (EGB) model is considered. For diagonal cosmological metrics, the equations of motion are written as a set of Lagrange equations with the effective Lagrangian containing two "minisuperspace" metrics on R^n: a 2-metric of pseudo-Euclidean signature and a Finslerian 4-metric proportional to the n-dimensional Berwald-Moor 4-metric. For the case of the "pure" Gauss-Bonnet model, two exact solutions are presented, those with power-law and exponential dependences of the scale factors (w.r.t. the synchronous time variable). (The power-law solution was considered earlier by N. Deruelle, A. Toporensky, P. Tretyakov, and S. Pavluchenko.) In the case of EGB cosmology, it is shown that for any non-trivial solution with an exponential dependence of scale factors, a_i(τ) = A_i exp(v^i τ), there are no more than three different numbers among v^1, ..., v^n.

DEVELOPMENT OF AN INNOVATIVE LIBS SYSTEM FOR ON-LINE QUANTITATIVE ANALYSIS OF RAW COAL.
Creators: name: REDOGLIO, DANIELE ANDREA
Publisher: name: Universit� degli Studi di Milano
Year: 2015

description: Every day in the world 64?125 GWh of electricity are produced and consumed: to satisfy this huge demand, many different power sources are employed, and in the last years the renewable energies share has kept on increasing. However, coal is still the main energy source and, thanks to the huge growth of China energy production, the amount of electrical energy produced this way is increasing: every day 12.1 million tons of coal are burned to fulfill 40% of the global electrical energy demand. In Italy, even if only 16.7% of the total power generation is obtained with coal combustion, coal is still the third power source, after natural gas and hydroelectric, and we have to import it in the amount of 17.5 million tons every year. Coal has an extremely variable composition, and heat power, pollutants generation and, consequently, cost, strongly depends on that composition; for these reasons whoever deals in coal is always on the look for instruments that allow to perform faster and more accurate analysis of coal composition. Devices able to perform on-line quantitative analysis of coal chemical composition are already commercially available; however, they are extremely expensive and must undergo strict regulations, due to the fact they employ either x-rays, gamma rays or neutrons. On the other hand, laser induced breakdown spectroscopy, or LIBS, has proven itself as a cost effective solution and has found many applications in other fields. In my Ph.D. thesis I have developed a working prototype for on-line quantitative analysis of coal based on LIBS, following every step of its realization. The main task has been the design and realization of an innovative collection optic that allows to perform measures on raw coal, at a distance of 1 meter from a conveyor belt; the innovative part consists in the fact that it doesn?t resort to the use of moving parts, decreasing its cost and increasing its reliability. My tasks also included the development of the software for data collection and analysis, the test of the instrument and its calibration . I have been deeply involved also into the choice of the components and the design of an instrument for the test in a real power plant.

description: Nowadays, the atmospheric pollution entails a huge problem of public health and environmental conservation, increasing the necessity of creating new policies to regulate the emissions and to reduce the impact of this in the global climate. These characteristics make the aerosols the central topic of research in the current years. The composition of the particulate matter present in the atmosphere is so varied, being difficult to determine all the species present, and so, relate the pollution with precise sources. Aerosol particles are involved in several atmospheric processes, such as cloud formation, precipitation and in the change of the optical properties, enhancing the absorbing and scattering by the particles. They have an effect in the distribution and abundance of the trace gases due to the participation in heterogeneous chemical reactions In this work, we have direct the aim of the project to the development of extraction methods in order to improve the recovery of the different components and use new analytical techniques to obtain a more detailed characterization of molecular markers, molecules that can be linked to one emission source which help to identify them. The developed analytical techniques have been further applied to three different cases of study: - A full characterization of the components in an urban background site, with a special interest on the organic fraction and the characterization of single molecules that act as markers of specific sources of emission. - Analysis of the water soluble organic fraction in a rural site in the frame of the quantification of the contribution to the atmospheric pollution of biological aerosol. - Analysis of water soluble organic compounds in a marine environment to identify the effect of harbour activities in the air quality of the cities.

Circa 12 miliardi di anni fa, quando l'universo era ancora adolescente, la galassia Xmm-2599 aveva già una massa di oltre 300 miliardi di soli. Uno studio ha ora dimostrato che la formazione stellare era stata, fino a quel momento, incredibilmente attiva per poi, improvvisamente e per ragioni ancora sconosciute, cessare completamente. Nella scoperta sono coinvolti anche tre astrofisici dell’Inaf: Francesco La Barbera,  Mario Nonino e Paolo Saracco

description: Canine atopic dermatitis (cAD) is a common inflammatory skin disease that is treated with medicines or allergen-specific immunotherapy. An improvement diet can help treatment of cAD. The purpose of this study was compare two diets on clinical and immunological parameters in atopic dogs without food hypersensitivity. Diet A, a commercial based on rice, was offered to 22 atopic dogs during 30 days and Diet B (grain free, rich in salmon) was given to 8 atopic dogs. Clinical scores were assessed by CADESI-4 and PVAS at the beginning (T0) and at the end of the study (T30). CD4+ and CD8+ were measured in PBMCs, and serum cytokines (TNF-α, IL-10, IL-31 and IL-34) were determined. Both diets decreased CADESI-4 score and Diet A decreased PVAS score (p < 0.05). There were no statistical significant differences between diets at T30 for CD4+ and CD8+. A decrease in the IL-31 concentrations and increase in IL-10 levels (p < 0.05) was observed with Diet A at T30. There were no differences between any of the two diets when the other results at T0 and T30 were compared for any of the parameters analysed. In conclusion, the results indicate that dietary intervention had not influence on cellular component of the immune system, but a positive effect was observed on IL-31, IL-10 serum levels for Diet A. Further studies are needed to enrich dietary components of the food for atopic dogs without food hypersensibility to help improvement the management of the cAD.

AVERAGING THEOREMS FOR NLS:PROBABILISTIC AND DETERMINISTIC RESULTS
Creators: name: TURRI, LUCA
Publisher: name: Universit� degli Studi di Milano
Year: 2019

description: In this thesis, we study the dynamics of NLS, in particular, we deal with the problem of the construction of prime integrals, either in the probabilistic or in the deterministic case. In the first part of the thesis, we consider the non linear Schr�dinger equation on the one dimensional torus with a defocusing polynomial nonlinearity and we study the dynamics corresponding to initial data in a set of a large measure with respect to the Gibbs measure. We prove that along the corresponding solutions the modulus of the Fourier coefficients is approximately constant for long time. The proof is obtained by adapting to the context of Gibbs measure for PDEs some tools of Hamiltonian perturbation theory. In the second part, we consider the nonlinear Schr�dinger equation on the two dimensional torus with a time-dependent nonlinearity starting with cubic terms. In this case, using perturbation theory techniques, we construct an approximate integral of motion that change slowly for initial data with small H^1-norm, this allows to ensure long time existence of solutions in H^1 on the two dimensional torus. The main difficulty is that H^1 on the two dimensional torus is not an algebra.

GR models of the X-ray spectral variability of MCG--6-30-15

description: We study in detail the GR models of the X-ray spectral variability for various geometries of the X-ray source and with various relativistic effects being the dominant cause of spectral variability. The predicted properties are compared with the Suzaku observational data of the Seyfert 1 galaxy MCG--6-30-15. The data disfavor models with the X-ray source (1) moving vertically on the symmetry axis or (2) corotating with the disc and changing height not far above the disc surface. The most likely explanation for the observed variability is given by the model involving the X-ray source located at a very small, varying distance from a rapidly rotating black hole. This model predicts some enhanced variations in the red wing of the Fe line, which are not seen in the Suzaku observations. However, the enhanced variability of the red wing, while ruled out by the Suzaku data, is consistent with an excess RMS variability, between 5 and 6 keV, reported for some previous ASCA and XMM observations. We speculate that the presence or lack of such a feature is related to the change of the ionization state of the innermost part of the disc, however, investigation of such effects is currently not possible in our model (where a neutral disc is assumed). If the model, completed by description of ionization effects, proves to be fully consistent with the observational data, it will provide a strong indication that the central black hole in MCG--6-30-15 rotates rapidly, supporting similar conclusions derived from the Fe line profile.

description: A transfer matrix approach to study ballistic charge transport in few-layer graphene with chiral-symmetric stacking configurations is developed. We demonstrate that the chiral symmetry justifies a non-Abelian gauge transformation at the spectral degeneracy point (zero energy). This transformation proves the equivalence of zero-energy transport properties of the multilayer to those of the system of uncoupled monolayers. Similar transformation can be applied in order to gauge away an arbitrary magnetic field, weak strain, and hopping disorder in the bulk of the sample. Finally, we calculate the full-counting statistics at arbitrary energy for different stacking configurations. The predicted gate-voltage dependence of conductance and noise can be measured in clean multilayer samples with generic metallic leads.

Durante i due anni in cui è stata osservata dalla sonda Rosetta dell’Esa, la cometa 67/P Churyumov-Gerasimenko ha ciclicamente mutato il proprio colore. Un enorme lavoro di elaborazione dei dati raccolti dallo strumento italiano Virtis ha infatti mostrato come il suo nucleo abbia progressivamente perso il colore rosso avvicinandosi al Sole, per poi tornare ad arrossire una volta tornata nello spazio profondo. Le particelle di polvere nella chioma, al contrario, hanno gradualmente virato al colore blu allontanandosi dal Sole. Il colore della 67/P cambierebbe in base alla quantità di ghiaccio d’acqua esposto in superficie e nei grani di polvere nella chioma della cometa

description: We study the evolution of linear density fluctuations of free-streaming massive neutrinos at redshift of z<1000, with an explicit justification on the use of a fluid approximation. We solve the collisionless Boltzmann equation in an Einstein de-Sitter (EdS) universe, truncating the Boltzmann hierarchy at lmax=1 and 2, and compare the resulting density contrast of neutrinos, δ_ν^{fluid}, with that of the exact solutions of the Boltzmann equation that we derive in this paper. Roughly speaking, the fluid approximation is accurate if neutrinos were already non-relativistic when the neutrino density fluctuation of a given wavenumber entered the horizon. We find that the fluid approximation is accurate at few to 25% for massive neutrinos with 0.05
description: 18 pages, 7 figures. (v2) with up-dated reference, minor typos corrected. (v3) An error in the normalization on the scale factor has been corrected. We now find that the fluid approximation is accurate at a few~25% accuracy. This version supersedes the published version.

A sedimentation study of the Slocan series, Sandon area, British Columbia
Creators: name: Kierans, Martin De Valera
Publisher: name: University of British Columbia
Year: 2012

description: A study of the Slocan Series of South Eastern British Columbia along the three related paths of Lithology, Biology and Tectonics is made. The Lithotopes studied are mainly microscopic, though some megascopic characters are used to determine bottom conditions. The microscopic work was done on slides made from specimens taken at random on a cross-section of these sediments from near Zincton B.C. along the valleys of Seaton and Carpenter Creeks, to New Denver, B.C. The specimens indicated an increase of grain size and feldspar content from the bottom of the section towards the top. This is correlated with an increase in sediment supply and rate of subsidence. The fossils found by Cairnes show that these sediments were laid down in marine waters. A study of lithologic assemblages and types leads to some hypotheses. These, taken with a study of the Windermere geosynclinal assemblage, and theoretical considerations based on the orogenic cycle, allow a history of the area to be made. This history indicates that the Slocan Series, while the result of a separate downwarp of the crust, is probably part of the complex Purcell-Windermere geosynclinal sequence.

description: Path integral formulation of quantum mechanics (and also other equivalent formulations) depends on a Lagrangian and/or Hamiltonian function that is chosen to describe the underlying classical system. The arbitrariness presented in this choice leads to a phenomenon called Quantization ambiguity. For example both $L_1=\dot{q}^2$ and $L_2=e^\dot{q}$ are suitable Lagrangians on a classical level ($δL_1=0=δL_2$), but quantum mechanically they are diverse. This paper presents a simple rearrangement of the path integral to a surface functional integral. It is shown that the surface functional integral formulation gives transition probability amplitude which is free of any Lagrangian/Hamiltonian and requires just the underlying classical equations of motion. A simple example examining the functionality of the proposed method is considered.
