description: A prototype multiwire proportional chamber (MWPC) was developed to demonstrate the feasibility of constructing a radiopure time projection chamber with MWPC track readout to assay materials for alpha- and beta-emitting surface contaminants for future rare-event-search experiments as well as other scientific fields. The design features and assembly techniques described here are motivated by the position and energy resolution required to reconstruct alpha and beta tracks while efficiently rejecting backgrounds. Results from a test setup using an $^{55}$Fe x-ray source indicate excellent operational stability and a near-ideal energy resolution of 15.8% FWHM at 5.89 keV and a gas gain of $\sim$10$^{4}$.

description: A prescription to calculate the minimum number of bits needed for binary strip detector readout is presented. This permits a systematic analysis of the readout efficiency relative to this theoretical minimum number of bits. Different level efficiencies are defined to include context information and engineering properties needed for reliable transmission, such as DC-balance. A commonly used encoding method is analyzed as an example and found to have an efficiency only of order 50%. A new encoding method called Pattern Overlay Compression is introduced to illustrate how the systematic analysis can guide the construction of more efficient readout methods. Pattern Overlay Compression significantly outperforms the above example in the occupancy range of interest.

description: In view of its local character, the semiclassical or Boltzmann theory is intrinsically unable to describe transport phenomena on ultrashort space and time scales, and to this purpose genuine quantum-transport approaches are imperative. By employing a density-matrix simulation strategy recently proposed, we shall demonstrate its power and flexibility in describing quantum-diffusion phenomena in nanoscale semiconductors. In particular, as for the case of carrier-carrier relaxation in photoexcited semiconductors, our analysis will show the failure of simplified dephasing models in describing phonon-induced scattering non-locality, pointing out that such limitation is particularly severe for the case of quasielastic dissipation processes.

description: Inspired by recent conflicting views on the order of the phase transition from an antiferromagnetic Neel state to a valence bond solid, we use the functional renormalization group to study the underlying quantum critical field theory which couples two complex matter fields to a non-compact gauge field. In our functional renormalization group approach we only expand in covariant derivatives of the fields and use a truncation in which the full field dependence of all wave-function renormalization functions is kept. While we do find critical exponents which agree well with some quantum Monte Carlo studies and support the scenario of deconfined criticality, we also obtain an irrelevant eigenvalue of small magnitude, leading to strong corrections to scaling and slow convergence in related numerical studies.

description: A twistor model of a free massless spinning particle in 4-dimensional Minkowski space is studied in terms of spacetime and spinor variables. This model is specified by a simple action, referred to here as the gauged Shirafuji action, that consists of twistor variables and gauge fields on the 1-dimensional parameter space. We consider the canonical formalism of the model by following the Dirac formulation for constrained Hamiltonian systems. In the subsequent quantization procedure, we obtain a plane-wave solution with momentum spinors. From this solution and coefficient functions, we construct positive-frequency and negative-frequency spinor wave functions defined on complexified Minkowski space. It is shown that the Fourier-Laplace transforms of the coefficient functions lead to the spinor wave functions expressed as the Penrose transforms of the corresponding holomorphic functions on twistor space. We also consider the exponential generating function for the spinor wave functions and derive a novel representation for each of the spinor wave functions.

description: The AMS-02 collaboration has recently presented measurements of excellent quality of the cosmic electron and positron fluxes as well as the positron fraction. We use the measurements of the positron flux to derive, for the first time, limits on the dark matter annihilation cross section and lifetime for various final states. Working under the well-motivated assumption that a background positron flux exists from spallations of cosmic rays with the interstellar medium and from astrophysical sources, we find strong limits on the dark matter properties which are competitive, although slightly weaker, than those derived from the positron fraction. Specifically, for dark matter particles annihilating only into e+ e- or into mu+ mu-, our limits on the annihilation cross section are stronger than the thermal value when the dark matter mass is smaller than 100 GeV or 60 GeV, respectively.

description: We study point-contact tunneling in the integer quantum Hall state of bosons. This symmetry-protected topological state has electrical Hall conductivity equal to $2 e^2/h$ and vanishing thermal Hall conductivity. In contrast to the integer quantum Hall state of fermions, a point contact can have a dramatic effect on the low energy physics. In the absence of disorder, a point contact generically leads to a partially-split Hall bar geometry. We describe the resulting intermediate fixed point via the two-terminal electrical (Hall) conductance of the edge modes. Disorder along the edge, however, both restores the universality of the two-terminal conductance and helps preserve the integrity of the Hall bar within the relevant parameter regime.

The imprint of dark matter haloes on the size and velocity dispersion evolution of early-type galaxies

description: Early-type galaxies (ETGs) are observed to be more compact, on average, at $z \gtrsim 2$ than at $z\simeq 0$, at fixed stellar mass. Recent observational works suggest that such size evolution could reflect the similar evolution of the host dark matter halo density as a function of the time of galaxy quenching. We explore this hypothesis by studying the distribution of halo central velocity dispersion ($σ_0$) and half-mass radius ($r_{\rm h}$) as functions of halo mass $M$ and redshift $z$, in a cosmological $Λ$-CDM $N$-body simulation. In the range $0\lesssim z\lesssim 2.5$, we find $σ_0\propto M^{0.31-0.37}$ and $r_{\rm h}\propto M^{0.28-0.32}$, close to the values expected for homologous virialized systems. At fixed $M$ in the range $10^{11} M_\odot \lesssim M\lesssim 5.5 \times 10^{14} M_\odot$ we find $σ_0\propto(1+z)^{0.35}$ and $r_{\rm h}\propto(1+z)^{-0.7}$. We show that such evolution of the halo scaling laws is driven by individual haloes growing in mass following the evolutionary tracks $σ_0\propto M^{0.2}$ and $r_{\rm h}\propto M^{0.6}$, consistent with simple dissipationless merging models in which the encounter orbital energy is accounted for. We compare the $N$-body data with ETGs observed at $0\lesssim z\lesssim3$ by populating the haloes with a stellar component under simple but justified assumptions: the resulting galaxies evolve consistently with the observed ETGs up to $z \simeq 2$, but the model has difficulty reproducing the fast evolution observed at $z\gtrsim 2$. We conclude that a substantial fraction of the size evolution of ETGs can be ascribed to a systematic dependence on redshift of the dark matter haloes structural properties.

description: We investigate the thermodynamics of the flavour sector of the Sakai-Sugimoto model in the presence of a magnetic field. Renormalizing the euclidean Dirac-Born-Infeld action in the antipodal limit, we find for the confined and deconfined phases positive contributions to the pressures that grow with the magnetic field. We also obtain positive magnetic susceptibilities indicating a paramagnetic behaviour of quarks. Using these results we estimate a λ^2/N_c correction to the deconfinement temperature that decreases as a function of the magnetic field.

description: Introduction: Although experimental studies demonstrated that platelets are pro-inflammatory cells, no randomized studies tested the anti-inflammatory effect of antiplatelet agents in humans. The platelet P2Y12 receptors mediated bronchial inflammation in a mouse model of asthma, suggesting that P2Y12 represents a pharmacological target for asthma. Objectives: In this proof-of concept, placebo-controlled, randomized, cross-over study we tested the effects of the P2Y12 antagonist prasugrel on bronchial hyper-reactivity of asthmatic patients. Patients/Methods: Twenty-six asthmatic patients were randomly and blindly allocated to prasugrel (10mg o.d.) or placebo for 15 days. After ?15-day wash-out, patients were crossed-over to the alternative treatment. Before and after each treatment, patients underwent bronchial provocation test with mannitol and measurement of fractional exhaled nitric oxide (FeNO). Inhibition of P2Y12-dependent platelet reactivity (PRI) was measured by the VASP phosphorylation assay. Results: The provocative dose of mannitol causing a 15%-drop in FEV1 tended to increase from 142 mg (95%CI 82-202) to 187 mg (113-262) after prasugrel (p=0.09) and did not change after placebo (136 mg; 76-196 and 144 mg; 84-204 , p=0.65). FeNO did not change after either treatment. PRI decreased from 80%(77-83) to 23%(7-29) after prasugrel (p<0.001) and remained unchanged after placebo. Conclusions: Our proof-of-concept, randomized, controlled study is the first one to test in vivo the anti-inflammatory effects of platelet inhibition in human patients. Its results suggest that pharmacological inhibition of P2Y12 receptors may slightly reduce the bronchial inflammatory burden and lays the groundwork for further studies, with clinical end-points. ?

description: Using the recently proposed differential hierarchy (Z-expansion) technique, we obtain a general expression for the HOMFLY polynomials in two arbitrary symmetric representations of link families, including Whitehead and Borromean links. Among other things, this allows us to check and confirm the recent conjecture of arXiv:1304.5778 that the large representation limit (the same as considered in the knot volume conjecture) of this quantity matches the prediction from mirror symmetry consideration. We also provide, using the evolution method, the HOMFLY polynomial in two arbitrary symmetric representations for an arbitrary member of the one-parametric family of 2-component 3-strand links, which includes the Hopf and Whitehead links.

description: The apex atom of a W scanning probe tip reveals a non-spherical charge distribution as probed by a CO molecule bonded to a Cu(111) surface [Welker et al. Science, 336, 444 (2012)]. Three high-symmetry images were observed and related to three low-index crystallographic directions of the W bcc crystal. Open questions remained, however, including the verification that the tip was indeed W-terminated, and whether this method can be easily applied to distinguish other atomic species. In this work, we investigate bulk Cu and Fe tips. In both cases we can associate our data with the fcc (Cu) and bcc (Fe) crystal structures. A model is presented, based on the partial filling of d orbitals, to relate the AFM images to the angular orientation of the tip structure.

DEVELOPMENT OF MOUSE MODELS OF ORAL SQUAMOUS CELL CARCINOMA (OSCC) METASTASIS FOR THE EVALUATION OF EMERGING ANTI-METASTATIC NANOMEDICINE DRUGS

description: Oral Squamous Cell Carcinoma (OSCC) is included in the Head and Neck Squamous Cell Carcinoma (HNSCC) group, which is the sixth most common cancer diagnosed worldwide. While the locoregional control has been increased thanks to the combination therapy, the incidence of distant metastasis is increasing. Nanomedicine therapies have been clinically approved for the treatment of several types of cancers and were used in few clinical trials on HNSCC patients. However, the efficacy of nanomedicine therapies was limited, especially for the treatment of metastatic OSCC. In the preclinical setting, more advanced nanomedicine platforms have been developed against metastatic cancers. One of this platform, iNPG-pDox, obtained promising results against lung metastasis in a preclinical model of breast cancer. The lungs are the most common site of distant metastasis reported in OSCC and there is an unmet need for novel therapies targeting distant metastasis. The aim of the present work was to establish two preclinical models of OSCC lung metastasis by orthotopic and tail vein injection of OSCC cells and to perform preliminary in vitro evaluations of pDox nanoparticles in two cell lines of metastatic OSCC (HSC-3 and HSC-3 M1, isolated from HSC- 3 lung metastases). In vitro, pDox nanoparticles were able to effectively kill both HSC-3 and HSC-3 M1 cells, without any significant difference between the two cell lines. In vivo, lung metastases of OSCC were observed in both preclinical models. In particular, the orthotopic model also developed regional lymph node metastases, characteristic of metastatic growth observed in OSCC patients. The other model obtained by tail vein injection presented only lung metastases. Therefore, orthotopic models should be preferred to non-orthotopic models for the preclinical evaluation of anti-metastatic nanomedicine therapies such as iNPG-pDox in OSCC. Moreover, such preclinical model of OSCC lung metastasis may be used to investigate the molecular mechanisms of OSCC regional and distant metastasis, which are still poorly understood.

description: We consider a class of gauged linear sigma models (GLSMs) in two dimensions that flow to non-compact (2,2) superconformal field theories in the infra-red, a prototype of which is the SL(2,\IR)/U(1) (cigar) coset. We compute the elliptic genus of the GLSMs as a path-integral on the torus using supersymmetric localization. We find that the result is a Jacobi-like form that is non-holomorphic in the modular parameter $τ$ of the torus, with mock modular behavior. This agrees with a previously-computed expression in the cigar coset. We show that the lack of holomorphicity of the elliptic genus arises from the contributions of a compact boson with momentum and winding around the torus. This boson has an axionic shift symmetry and plays the role of a compensator field that is needed to cancel the chiral anomaly in the rest of the theory.

GM-CSF AND MMP9 ARE KEY REGULATORS OF THE EFFECT OF ADIPOSE PROGENITORS OVER BREAST CANCER ONSET AND METASTATIC PROGRESSION

description: Recent epidemiological and clinical data underlined the critical role of obesity in breast cancer (BC) progression. Among several white adipose tissue (WAT) cells, which may promote a permissive tumor microenvironment, a population with progenitor-like phenotype (CD45-CD34+) was reported to support local and metastatic BC. This population is composed by distinct WAT progenitors: adipose-derived stem cells (ASCs) and endothelial progenitor cells (EPCs), displaying complementary role in BC progression in preclinical models. However, molecular mechanisms involved in this interaction have been so far elusive and need to be clarified. An extensive screening of candidate molecules revealed two proteins being significantly up-regulated in WAT-derived progenitors after being co-cultured with several BC cells: Granulocyte-macrophage colony-stimulating factor (GM-CSF) and Matrix metallopeptidase 9 (MMP9). Both factors were detected over-expressed in orthotopic xenograft models, when co-injected with BC and human WAT progenitors. ASC and EPCs displayed similar ability to induce GM-CSF/MMP9, suggesting a complementary role in their release. GM-CSF neutralization in WAT progenitors inhibited MMP9 secretion, which was also reduced by IL-1? neutralization. GM-CSF displayed an additional positive feedback regulation on its own release. The inhibition of GM-CSF in diet-induced obese (DIO) syngeneic mice led to reduced intratumor vascularization and strong impairment of immunosuppressive microenvironment, targeting mainly tumor-associated macrophages (TAMs), myeloid derived suppressor cells (MDSCs) and T-regulatory (T-regs) cells. This resulted in a significant impairment of local BC growth and a slower metastatic progression. Conversely, MMP9 inhibition reduced neoplastic angiogenesis and significantly decreased local and metastatic tumor growth. The combined GM-CSF/MMP9 inhibition synergically impaired tumor angiogenesis, local and metastatic BC growth. Metformin was reported to significantly affect tumor progression and neoplastic angiogenesis, targeting both BC and WAT cells. In the present study, Metformin inhibited GM-CSF and MMP9 release from WAT progenitors in vitro and in xenograft models. Metformin had similar effects of GM-CSF/MMP9 specific inhibitions in DIO syngeneic mice, but was more effective in reducing tumor angiogenesis and targeted different immune cells. Collectively, these results indicate GM-CSF and MMP9 as new potential targets to prevent the pro-tumorigenic effect of WAT progenitors on BC. Furthermore, Metformin ability to reduce GM-CSF and MMP9 supports Metformin administration in clinical studies on BC, especially in a setting of obesity and/or insulin resistance.

description: Mycotoxins, secondary metabolites produced by moulds, mainly Aspergillus spp., Fusarium spp. and Penicillium spp., are common contaminants of food and feed. The aim of this project was to evaluate: (i) the potential endocrine disruptor effects of fumonisin B1 (FB1), beauvericin (BEA), deoxynivalenol (DON) and zearalenone (ZEA) metabolites ?-zearalenol (?-ZEA) and ?zearalenol (?ZEA), alone and combined, using a bovine granulosa cell (GC) in vitro model and (ii) the individual and combined effects of FB1 and BEA on the intestinal barrier using Caco-2 cells cultured in vitro on semipermeable inserts. The results obtained indicated that FB1 alone at all tested doses (0; 0.5; 1; 1.5; 3; 6 ?M) had no effects on GC proliferation and progesterone (P4) production. In the presence of ?ZEA at30 ng/mL (0.094 ?M), FB1 at 30 ng/mL (0.042 ?M) showed a stimulatory effect on GC numbers. Cell proliferation decreased after exposure to ?ZEA alone at 5.0 mg/mL (15.6 ?M) and FB1 with ?-ZEA and ?ZEA at the same concentration. Regarding steroid production, FB1 at 30 ng/mL (0.042 ?M ) and 100 ng/mL (0.13 ?M amplified the inhibitory effect of ?ZEA at 30 ng/mL (0.094 ?M) on estradiol (E2) production, while FB1 alone increased (P<0.05) IGF1-induced E2 production. FB1 in combination with ?ZEA decreased (P < 0.05) E2 production. FB1 at 1, 1.5 and 3 ?M slightly inhibited (P < 0.05) E2 production. BEA at concentrations ? 3 ?M was found to strongly decrease (P < 0.05) both steroid production and FB1 did not influence the effects of BEA. At 10 ?M both mycotoxins decreased (P < 0.001) serum-induced GC proliferation. At 30 ?M, BEA showed inhibitory effects on FSH plus IGF-1-induced CYP11A1 and CYP19A1 mRNA abundance (P < 0.05), whereas FB1 at 30 ?M had no effect on CYP11A1 and CYP19A1 gene expression. As regards the effects of FB1 and BEA, alone and combined, on the Caco-2 intestinal barrier model data showed a TEER decrease after 1 h and 2 h of Bl exposure to BEA at 0.5 and 1.5 ?M and after 24 h of Bl exposure to BEA at 0.5 ?M, whereas after 24 h of Bl exposure, BEA at 3 and 6 ?M was found to significantly (P < 0.05) increase TEER. FB1 had no effect on the intestinal barrier integrity and when combined with BEA the TEER increase induced by BEA was no longer observed. Cytokine release was observed only after exposure to BEA alone, and not in combination with FB1, with an increase of IL-6 and IL8 release after apical exposure to 3 and 6 ?M and after basolateral exposure to 1.5, 3, 6 ?M for IL-6 and only to 6 ?M for IL-8. TNF- ? release was induced by Ap (0.5 -1.5 ?M) and Bl (1.5 ?M) exposure to BEA. Overall, these results provide information on in vitro toxicological effects of Fusarium mycotoxins.

description: Le gouvernement du Canada rapporte un taux d'abandon se situant en moyenne autour de 50% au doctorat (Universités Canada, 2020). Parmi les causes sous-jacentes entraînant l’interruption du programme d'études se trouve le manque d'expérience et de compétences en rédaction universitaire (Lison et Bourget, 2016). Cette lacune peut freiner la progression des étudiants dans leurs études, mais aussi, leur intégration à une communauté universitaire comme chercheurs novices. En effet, les études doctorales permettent la socialisation au métier de chercheur, alors le doctorant se doit d'intégrer les normes et les pratiques s'y rattachant (Skakni, 2011). À cette fin, il existe un dispositif qui se nomme cafés de rédaction universitaire (CRU), dont la popularité est en essor au Canada, comme dans d'autres pays occidentaux. Notre recherche doctorale de nature qualitative interprétative porte sur le phénomène de socialisation des doctorants au métier de chercheur. À ce sujet, elle vise à mieux comprendre les trajectoires de socialisation qui s'opérationnalisent entre des membres d'une communauté d’apprentissage dans le contexte des CRU. Les trajectoires de socialisation proviennent de la mise en relation des éléments de notre cadre théorique qui est composé des concepts de sentiment d'efficacité personnelle (Bandura, 1997) et d'attribution causale (Weiner, 1972). En tant qu'étude de cas instrumental (Stake, 1995), nous examinons une communauté d'apprentissage nommée Thèsez-vous Ensemble qui compte plus de 4 000 membres aux études supérieures. Pour ce faire, nous avons mené 25 entrevues semi-dirigées (Savoir-Zajc, 2009) avec des candidats au doctorat provenant de 12 universités canadiennes. Nous avons également effectué de la capture de textes numériques (Radford, 2019) à même le compte Facebook de la communauté où s'échangent des ressources utiles à la socialisation au métier de chercheur. Les résultats de la recherche ont révélé que la participation des candidats au doctorat à des CRU, en présence de leurs pairs, leur permet de rehausser leur sentiment d'efficacité personnelle et de mieux comprendre les causes attribuables à leurs réussites et leurs échecs rédactionnels. Notre étude a permis d'approfondir les connaissances face au phénomène de socialisation au métier de chercheur qui a été peu étudié dans des contextes non institutionnels. Nous avons aussi formulé des pistes d'exploration subséquentes face à des concepts théoriques, des approches méthodologiques et des terrains de recherche dans une approche multidisciplinaire en enseignement supérieur.

description: Swine are routinely used for studying human cardiopulmonary diseases due to similarities in anatomy and physiology, and for being close to humans in phylogeny. A swine model of chlorine inhalation injury recapitulated key human acute respiratory distress syndrome, including but not limited to hypoxemia, impaired respiratory physiological parameters, impaired pulmonary function, neutrophilic alveolitis, deposition of hyaline membranes in alveoli, formation of microthrombi in pulmonary parenchyma, and cytokine storm. Two different kinds of potential forensic diagnostic biomarkers have been identified in swine plasma and lung tissues.

Forma y contenido. Una interpretaci�n del idealismo brit�nico
Creators: name: CARDANI, MICHELE
Publisher: name: Universit� degli Studi di Milano
Year: 2017

description: Through a reflection on the notions of form and content originating from Kant?s philosophy, this work offers a new interpretation of British idealism. Its starting point consists in recognizing the heterodox character of the idealist doctrines developed in the United Kingdom as a result of the interpretations of the philosophies of Kant and Hegel. In order to achieve this goal, the influence of Kant?s philosophy on the metaphysical proposals of the philosophers on the other side of the English Channel is first discussed. The notions of form and content represent the gateway to criticism, and allow reasoning about the new concepts of experience and object that were proposed in the first Critique. Through to the analysis of Bradley?s logical doctrine of judgment (which is compared to the concept of existence in Kantian philosophy), and of McTaggart?s famous argument about the unreality of time (vastly different from the definitions of the Transcendental Aesthetic), the British idealists? approach is questioned, for it does not meet Kant?s presuppositions and requirements. This conclusion is also endorsed by the discussion of Stirling?s criticism to transcendental philosophy. However, since Hegel climbed the ladder of critical philosophy, raising his discourse to a level defined as ?meta-transcendental?, the suspension of criticism brings to the suspension of Hegelianism as well. The notions of form and content no longer lay in the sphere of transcendental subjectivity: the method of logic in its proceedings, i.e., its immanent connection and necessity as science, is the identity of form and content in the element of pure thought. The analysis shows that the British idealists do not comprehend the significance of Hegel?s absolute philosophy: not only do they lower it to a subjective method, but they also reformulate the principles of dialectic, so that pure thought remains subordinate to the concept of being. Since the genesis of analytical philosophy is commonly regarded as a reaction against idealism, the relevance of these considerations is not limited to their mere historical interest: by refuting the arguments of the German philosophers, analytic philosophy does not undermine those of the British idealists?and vice versa.

IL DE SECRETIS LIBER PRIMUS DI GIROLAMO CARDANO

description: The main aim of my Ph. D dissertation is the edition of the De secretis liber primus (Basilea 1562) of Girolamo Cardano (1501-1576). The thesis contains an introduction that relates the work of Cardano to natural philosophy of the Renaissance, the transcription of the editio princeps and the translation in Italian accompanied by a set of historical and philological notes. In the introduction I analyze the historical background of the pubblication of the De secretis and I compare Cardano's work with Renaissance books of secrets in particular with Conrad Gessner's Thesaurus Euonymi Philiatri de remediis secretis (Zurich 1552). The introduction examines the Cardanian method for the search of secrets and the relationship with his metaphysics and with his idea of lucrum.
