description: Using the variational approximation and numerical simulations, we study one-dimensional gap solitons in a binary Bose-Einstein condensate trapped in an optical-lattice potential. We consider the case of inter-species repulsion, while the intra-species interaction may be either repulsive or attractive. Several types of gap solitons are found: symmetric or asymmetric; unsplit or split, if centers of the components coincide or separate; intra-gap (with both chemical potentials falling into a single bandgap) or inter-gap, otherwise. In the case of the intra-species attraction, a smooth transition takes place between solitons in the semi-infinite gap, the ones in the first finite bandgap, and semi-gap solitons (with one component in a bandgap and the other in the semi-infinite gap).

description: Shear stresses are the driving forces for the creation of both point and extended defects in crystals subjected to high pressures and temperatures. Recently, we observed anomalous elastic materials response in shock-compressed silicon and diamond in the course of our MD simulations and were able to relate this phenomenon to non-monotonic dependence of shear stress on uniaxial compression of the material. Here we report results of combined density functional theory (DFT) and classical interatomic potentials studies of shear stresses in shock compressed covalent solids such as diamond and silicon for three low-index crystallographic directions, <100>, <110>, <111>. We observed a non-monotonic dependence of DFT shear stresses for all three crystallographic directions which indicates that anomalous elastic response of shock compressed material is a real phenomenon and not an artifact of interatomic potentials used in MD simulations.

description: We demonstrate a magnetometric technique based on nonlinear magneto-optical rotation using amplitude modulated light. The magnetometers can be operated in either open-loop (typical nonlinear magneto-optical rotation with amplitude-modulated light) or closed-loop (self-oscillating) modes. The latter mode is particularly well suited for conditions where the magnetic field is changing by large amounts over a relatively short timescale.

description: Irradiation of the strong light on the material leads to numerous non-linear effects that are essential to understand the physics of excited states of the system and for optoelectronics. Here, we study the non-linear thermoelectric effect due to the electric and thermal fields applied on a non-centrosymmetric system. The phenomenon arises on the Fermi surface with the transitions of electrons from valence to conduction bands. We derive the formlism to investigate these effects and find that the non-linearity in these effects namely non-linear Seebeck and non-linear Peltier effects depends on the ratio of the non-linear to the linear conductivities. The theory is tested for a hexagonally warped and gapped topological insulator. Results show enhancement in the longitudinal and Hall effects on increasing the warping strength while show opposite behavior with the surface gap.

description: In the framework of the recently proposed saturation picture, we examine in a systematic way whether the nuclear modification factor measured for d-Au collisions at RHIC may be simply explained. The Cronin peak which is obtained at mid-rapidity around $k_{\bot}\simeq 3$ GeV may be reproduced at the proper height only by boosting the saturation momentum by an additional nuclear component as already shown in the literature. In this respect, mid-rapidity RHIC data cannot necessarily be seen as a probe of the saturation picture. The large rapidity ($η\simeq 3$) region allows us to test the shape of the unintegrated gluon distribution in the nucleus, investigating various parameterizations inspired by large rapidity solutions (of the BFKL and) of the Balitsky-Kovchegov (BK) equation. A satisfactory description of $R_{CP}$ at RHIC is obtained in the BK picture.

description: Wormholes are hypothetical objects which can be black hole mimickers with strong gravitational fields. Recently, Wielgus et al. have constructed reflection-asymmetric thin-shell wormholes which are composed of the parts of a Schwarzschild spacetime and a Reissner-Nordstrom spacetime with two photon spheres with different sizes each other in [M. Wielgus, J. Horak, F. Vincent, and M. Abramowicz, Phys. Rev. D 102, 084044 (2020)]. They have discussed observational property of the shadows with two photon rings in different sizes as seen from an observer and they have named their shadows double shadows. In this paper, we study the linearization stability of the reflection-asymmetric thin-shell wormholes with the double shadows.

description: Nell'ambito della collaborazione con il Laboratorio Jefferson Lab, in Virginia-Stati Uniti, il Gruppo SanitàCollegato della Sezione INFN di Roma 1, ha realizzato un rivelatore di tipo "Ring Imaging Cherenkov"(RICH). Tale rivelatore é utilizzato in esperimenti di fisica degli ipernuclei, in Hall A al Jefferson Lab, sotto la responsabilitàitaliana, allo scopo di migliorare l'identificazione delle particelle (protone, pioni, mesoni K).Il piano di fotoconversione di fotoni Cherenkov emessi dalle particelle che attraversano un radiatore, nel rivelatore, rappresenta uno degli elementi più critici del rivelatore RICH.Il Gruppo Collegato ha progettato, costruito e messo a punto un sistema completo di deposizione di film di Ioduro di Cesio (CsI) su fotocatodi di dimensione 600x400 mm2, suddiviso in pad di 8x8 mm2. La presente nota descrive in dettaglio l'intero sistema consistente in un evaporatore di grandi dimensioni (altezza 1100 mm e diametro 1200 mm) con relativi sistemi di vuoto e di controllo.Le evaporazioni sino ad oggi realizzate hanno dato risultati eccellenti in termini di efficienza quantica di fotoconversione e le procedure tecniche utilizzate si sono dimostrate affidabili.
Tyrosine phosphorylation and activation of PYK2 in platelets: involvement in PI 3-kinase activation
Creators: name: Sayed, Mohamed Rabie
Publisher: name: University of British Columbia

description: Platelets play a central role in the hemostatic response. They also contribute significantly to the initiation of responses by other cells which occur concomitantly with, or as a necessary sequel to, the initial events that prevent loss of blood, and are directly involved in wide range of diseases. Platelets activate various intracellular signaling pathways in thrombus formation, upon blood vessel injury. These intracellular signaling events involve activation of protein-tyrosine kinases which play key regulatory roles in controlling platelet aggregation and in regulating the activity of p85/p110 form of PI 3-kinase. The exact mechanism leading to the activation of p85/PI 3-kinase through the G-protein-coupled receptor is not understood. We show, for the first time, a novel association of PYK2 with p85/PI 3-kinase. The activation of PYK2 and its association with PI 3-kinase were shown to be increased in a time dependent manner and uninhibited by RGDS peptide which blocks the interaction of ligands such as fibrin/fibrinogen with the platelet integrin GPIIb/IIIa. This was concomitant with increased PI 3-kinase activity and association in PYK2 immunoprecipitates. We also have shown that the PI 3-kinase inhibitor LY-294002 had no effect on the activity and association of PYK2 with PI 3-kinase. We suggest that a physical or functional association of PYK2 with PI 3-kinase may occur in vivo that is responsible for the initial activation of PI 3-kinase in thrombinstimulated human platelets independendy of integrin ligation. Furthermore, we observed major tyrosine phosphorylated proteins p115 and p102 were inducibly associated with p85/PI 3-kinase in PAF-stimulated rabbit and thrombin-stimulated human platelets respectively. These proteins were not immunoreactive with several antibodies in this molecular weight range known to be tyrosine phosphorylated and associate with PI 3- kinase on cell activation. We attempted to purify p115 which was shown to be composed of more than one polypeptide or different phosphorylation states of. the same polypeptide, p102 was shown to be inducibly associated with PI 3-kinase, but was dependent upon fibrinogen binding to the integrin. While there is some evidence of aggregation-dependent degradation of proteins in platelets involved a protein at 123 kD that immunoreacted with PYK2 antibody and could be a splice variant of PYK2, the exact mechanisms have not been clearly demonstrated. These events may influence the regulation of PYK2 and PI 3- kinase.

The aim of this paper is to provide a short and pedagogical introduction to the use of data compression techniques for the estimate of entropy and other relevant quantities in Information Theory and Algorithmic Information Theory. We consider in particular the LZ77 algorithm as case study and discuss how a zipper can be used for information extraction.

Dephasing in the electronic Mach-Zehnder interferometer at filling factor 2

description: We propose a simple physical model which describes dephasing in the electronic Mach-Zehnder interferometer at filling factor 2. This model explains very recent experimental results, such as the unusual lobe-type structure in the visibility of Aharonov-Bohm oscillations, phase rigidity, and the asymmetry of the visibility as a function of transparencies of quantum point contacts. According to our model, dephasing in the interferometer originates from strong Coulomb interaction at the edge of two-dimensional electron gas. The long-range character of the interaction leads to a separation of the spectrum of edge excitations on slow and fast mode. These modes are excited by electron tunneling and carry away the phase information. The new energy scale associated with the slow mode determines the temperature dependence of the visibility and the period of its oscillations as a function of voltage bias. Moreover, the variation of the lobe structure from one experiment to another is explained by specific charging effects, which are different in all experiments. We propose to use a strongly asymmetric Mach-Zehnder interferometer with one arm being much shorter than the other for the spectroscopy of quantum Hall edge states.

description: HH 212 is a highly collimated jet discovered in H2 powered by a young Class 0 source, IRAS 05413-0104, in the L1630 cloud of Orion. We have mapped around it in 1.33 mm continuum, 12CO ($J=2-1$), 13CO ($J=2-1$), C18O ($J=2-1$), and SO ($J_K = 6_5-5_4$) emission at $\sim$ \arcs{2.5} resolution with the Submillimeter Array. A dust core is seen in the continuum around the source. A flattened envelope is seen in C18O around the source in the equator perpendicular to the jet axis, with its inner part seen in 13CO. The structure and kinematics of the envelope can be roughly reproduced by a simple edge-on disk model with both infall and rotation. In this model, the density of the disk is assumed to have a power-law index of $p=-1.5$ or -2, as found in other low-mass envelopes. The envelope seems dynamically infalling toward the source with slow rotation because the kinematics is found to be roughly consistent with a free fall toward the source plus a rotation of a constant specific angular momentum. A 12CO outflow is seen surrounding the H2 jet, with a narrow waist around the source. Jetlike structures are also seen in 12CO near the source aligned with the H2 jet at high velocities. The morphological relationship between the H2 jet and the 12CO outflow, and the kinematics of the 12CO outflow along the jet axis are both consistent with those seen in a jet-driven bow shock model. SO emission is seen around the source and the H2 knotty shocks in the south, tracing shocked emission around them.

Reinvented racism...reinventing racism?: interpreting immigration and reception in Richmond, BC
Creators: name: Rose, John Stanley
Publisher: name: University of British Columbia
Year: 2009

description: Since the liberalization of Canadian immigration policy in the late-1960s, a significant development has been the increase in the ethnic and racial diversity of Canada's population. Indeed, the visible minority status of many immigrants to Canada has powerfully shaped interpretations of social and physical change. In the context of substantial Asian immigration to Greater Vancouver, a number of commentators have argued that critical responses to change on the part of long-term Caucasian residents represent a 'reinvented', and often subtly expressed, racism. It is the contention of this author, however, that such conclusions are compromised by an uncritical assumption of what constitutes racism and a diminished empirical focus on sensationalized media accounts. Working from this premise, this thesis attempts to examine in greater depth two categories poorly examined in these accounts: racism and the long-term resident. It traces the emergence of the category of race, the analytical and political imperatives which gave rise to a shift in focus from race to racism, and how—under the rubric of social constructionism-—theories on racism have been deployed to understand contemporary social relations in Greater Vancouver. A critique of this literature provides the springboard for further analysis of long-term resident responses to change. Extended interviews conducted with fifty-four long-term residents of Richmond, BC—a Vancouver suburb that has received considerable numbers of Chinese immigrants over the past twelve years—strongly suggest that our understanding of social and physical change at the community level cannot be reduced to one dimension. Moreover, the complexity of these responses also demands that the analytical and political import of evaluative terms like racism be prised open and subjected to scrutiny and open debate. Perhaps most importantly, the diversity of long-term Richmond residents' responses cautions against the production of racialized stereotypes in immigration research, and points to the need to provide more nuanced and contextualized interpretations of immigration and its impact on society.

description: We perform a comprehensive study of noise-induced effects in a stochastic model of reaction-diffusion type, describing nano-structured thin films growth at condensation. We introduce an external flux of adsorbate between neighbour monoatomic layers caused by the electrical field presence near substrate in plasma-condensate devices. We take into account that the strength of the electric field fluctuates around its mean value. We discuss a competing influence of the regular and stochastic parts of the external flux onto the dynamics of adsorptive system. It will be shown that the introduced fluctuations induce first-order phase transition in a homogeneous system, govern the pattern formation in a spatially extended system; these parts of the flux control the dynamics of the patterning, spatial order, morphology of the surface, growth law of the mean size of adsorbate islands, type and linear size of surface structures. The influence of the intensity of fluctuations onto scaling and statistical properties of the nano-structured surface is analysed in detail. This study provides an insight into the details of noise induced effects at pattern formation processes in anisotropic adsorptive systems.

description: Coherent coupling between single quantum objects is at the heart of modern quantum physics. When coupling is strong enough to prevail over decoherence, it can be used for the engineering of correlated quantum states. Especially for solid-state systems, control of quantum correlations has attracted widespread attention because of applications in quantum computing. Such coherent coupling has been demonstrated in a variety of systems at low temperature1, 2. Of all quantum systems, spins are potentially the most important, because they offer very long phase memories, sometimes even at room temperature. Although precise control of spins is well established in conventional magnetic resonance3, 4, existing techniques usually do not allow the readout of single spins because of limited sensitivity. In this paper, we explore dipolar magnetic coupling between two single defects in diamond (nitrogen-vacancy and nitrogen) using optical readout of the single nitrogen-vacancy spin states. Long phase memory combined with a defect separation of a few lattice spacings allow us to explore the strong magnetic coupling regime. As the two-defect system was well-isolated from other defects, the long phase memory times of the single spins was not diminished, despite the fact that dipolar interactions are usually seen as undesirable sources of decoherence. A coherent superposition of spin pair quantum states was achieved. The dipolar coupling was used to transfer spin polarisation from a nitrogen-vacancy centre spin to a nitrogen spin, with optical pumping of a nitrogen-vacancy centre leading to efficient initialisation. At the level anticrossing efficient nuclear spin polarisation was achieved. Our results demonstrate an important step towards controlled spin coupling and multi-particle entanglement in the solid state.

Especially we clarify the roles of the Z_2-odd N=1 multiplets in such an off-shell dimensional reduction. Their equations of motion provide constraints on the Z_2-even multiplets and extract the zero modes from the latter. The procedure can be applied to wide range of models and performed in a background-independent way. We demonstrate it in some specific models.

description: We study the effective resistance of small-world resistor networks. Utilizing recent analytic results for the propagator of the Edwards-Wilkinson process on small-world networks, we obtain the asymptotic behavior of the disorder-averaged two-point resistance in the large system-size limit. We find that the small-world structure suppresses large network resistances: both the average resistance and its standard deviation approaches a finite value in the large system-size limit for any non-zero density of random links. We also consider a scenario where the link conductance decays as a power of the length of the random links, $l^{-α}$. In this case we find that the average effective system resistance diverges for any non-zero value of $α$.

description: We investigate the nonequilibrium behavior of a one-dimensional binary fluid on the basis of Boltzmann equation, using an infinitely strong shock wave as probe. Density, velocity and temperature profiles are obtained as a function of the mixture mass ratio μ. We show that temperature overshoots near the shock layer, and that heavy particles are denser, slower and cooler than light particles in the strong nonequilibrium region around the shock. The shock width w(μ), which characterizes the size of this region, decreases as w(μ) ~ μ^{1/3} for μ-->0. In this limit, two very different length scales control the fluid structure, with heavy particles equilibrating much faster than light ones. Hydrodynamic fields relax exponentially toward equilibrium, ϕ(x) ~ exp[-x/λ]. The scale separation is also apparent here, with two typical scales, λ_1 and λ_2, such that λ_1 ~ μ^{1/2} as μ-->0$, while λ_2, which is the slow scale controlling the fluid's asymptotic relaxation, increases to a constant value in this limit. These results are discussed at the light of recent numerical studies on the nonequilibrium behavior of similar 1d binary fluids.

description: During the runs of the PS 179 experiment at LEAR of CERN, we photographed an event of antiproton-Ne absorption, with a complete pi+ -> mu+ ->e+ chain. From the vertex of the reaction a very slow energy pi+ was emitted. The pi+ decays into a mu+ and subsequently the mu+ decays into a positron. At the first decay vertex a muon neutrino was emitted and at the second decay vertex an electron neutrino and a muon antineutrino. Measuring the pion and muon tracks and applying the momentum and energy conservation and using a classical statistical interval estimator, we obtained an experimental upper limit for the muon neutrino mass: m_nu < 2.2 MeV at a 90% confidence level. A statistical analysis has been performed of the factors contributing to the square value of the neutrino mass limit.

Social justice in health: the patient-centered medical home and health disparities
Creators: name: Anderson, Denise
Publisher: name: No Publisher Supplied
Year: 2021

description: Currently, the United States healthcare system is inequitable. It facilitates health disparities in the incidence, prevalence, mortality, and burden of disease among specific populations. These populations face inequities such as reduced healthcare access, lack of culturally competent care, discrimination, and poorer health outcomes. Despite the efforts of both Federally Qualified Health Centers (FQHCs) and the Patient-Centered Medical Home (PCMH) model, health disparities persist. There is currently no empirical evidence that the PCMH can reduce health disparities in populations impacted by health inequities. Guided by a constructivist perspective, this study utilized a convergent parallel mixed-methods design to examine the efficacy of the PCMH model in reducing health disparities in FQHCs. Four research questions were addressed: 1) Does the NCQA PCMH improve physical and mental health among low-income minority populations, particularly patients with diabetes, hypertension, coronary artery disease, obesity, and risk for depression in New Jersey? 2) What has been the patient experience in NCQA PCMH-recognized health centers serving low-income, minority groups in New Jersey? 3) What has been the health center staff experience in NCQA PCMH-recognized health centers serving low-income, minority groups in New Jersey? 4) What has been the health center staff experience in NCQA PCMH-recognized centers in New Jersey regarding burnout? Fifteen NCQA PCMH-recognized New Jersey FQHCs were included in the sample. Quantitative methods were used to examine 2016-2018 Uniform Data System (UDS) data, including quality of care measures for FQHC patients diagnosed with hypertension, diabetes, and coronary artery disease, as well as prevention screenings for obesity and depression. Qualitative content analysis was used to analyze 990 online Google FQHC patient reviews and 295 online Indeed FQHC employee reviews. A constructed hybrid framework guided the analysis. Study findings suggest the need to design a health care delivery model that reduces health disparities. Future research should examine other health care delivery models for their ability to reduce health disparities and explore the impact of public policies designed to address inequities. Targeted investment in FQHCs may yet yield an equitable and scalable health system that reduces health disparities and works for all regardless of racial, ethnic or socioeconomic status.

description: The theory for Bose-Einstein correlations in case of neutral gauge bosons in $pp$ collisions at high energies is presented. Based on quantum field theory at finite temperature the two-particle Bose-Einstein correlations of neutral gauge bosons are carried out for the first time. As a result, the important parameters of the correlation functions can be obtained for the $Z^{0}Z^{0}$ pairs. The correlations of two bosons in 4-momentum space presented in this paper offer useful and instructive complimentary viewpoints to theoretical and experimental works in multiparticle femtoscopy and interferometry measurements at hadron colliders.

description: Questa ricerca è stata affidata al gruppo Mailing dalla Commissione Calcolo e Reti, con lo scopo di indagare i diversi aspetti di un possibile servizio di posta centralizzato. Nelle sedi i servizi calcolo sono oggi impegnati a fornire lo stesso servizio di posta, quasi replicato, con grande impegno di personale e risorse. I vantaggi della centralizzazione del servizio sono evidenti: oltre a liberare i servizi dal carico di lavoro legato al servizio di posta, si utilizzerebbero le risorse hardware in modo più ottimizzato e si potrebbero implementare politiche di servizio, antispam e antivirus uniformi e più efficaci. Restano però ancora alcuni dubbi sulla convenienza di questa eventuale riorganizzazione: la grande complessitàintrodotta in un servizio sempre più critico, i costi elevati, la gestione del traffico locale e dell'allarmistica. La scelta dei sistemi e delle possibili soluzioni ha come presupposti:-	che il livello di servizio fornito sia uguale o superiore a quello attuale - che il sistema possa essere integrato nell'infrastruttura di AAI - che l'erogazione del servizio centralizzato liberi effettivamente il personale dei servizi dal carico di lavoro legato alla posta elettronica (sistemistico e di helpdesk). Le soluzioni commerciali che soddisfano queste richieste sono di due tipi:-	quelle che offrono le caselle di posta e gli strumenti per l'amministrazione ed ospitano e gestiscono l'hardware in maniera trasparente per il cliente, e costano circa 50 € per utente/anno (es. Google Apps) -	quelle che gestiscono il sistema ospitato presso il cliente, con costi simili alla soluzione precedente (Oracle, IBM) o non quantificabili a priori (es. Microsoft), ma comunque elevati.A costi decisamente minori, una soluzione opensource gestita completamente dall'INFN risulta tecnicamente complessa anche se non impossibile; richiede però l'identificazione di uno o più siti dove allestire l'infrastruttura necessaria, la progettazione, l'acquisto, l'installazione e la gestione di un sistema hardware scalabile e ad alta affidabilitàe l'istituzione di un apposito servizio con personale specializzato per la gestione e manutenzione del servizio e per l'helpdesk. L'introduzione del Metodo a Gerarchia Analitica (AHP: Analytic Hierarchy Process) ha permesso di valutare con criteri qualitativi, oltre che quantitativi, e secondo pesi diversi, le diverse alternative, confermando che l'attuale soluzione distribuita è tutt'ora la più adatta alle esigenze di servizio dell'Ente.

description: The antioxidant activity of baked foods is of utmost interest when envisioning enhancing their health benefits. Incorporating functional ingredients is challenging since their bioactivity naturally declines during baking. In this study, 3D food printing and design of experiments are employed to clarify how the antioxidant activity of cookies enriched with encapsulated polyphenols can be maximized. A synergistic effect between encapsulation, time, temperature, number of layers, and infill of the printed cookies was observed on the moisture and antioxidant activity. Four-layer cookies with 30 % infill provided the highest bioactivity and phenolic content if baked for 10 min and at 180 °C. The bioacitivity and total phenolic content improved by 115 % and 173 %, respectively, comparing to free extract cookies. Moreover, the proper combination of the design and baking variables allowed to vary the bioactivity of cooked cookies (moisture 3-5 %) between 300 to 700 μmolTR/gdry. The additive manufacture of foods with interconnected pores could accelerate baking and browning, or reduce thermal degradation. This represents a potential approach to enhance the functional and healthy properties of cookies or other thermal treated bioactive food products.

description: The study utilized atmospheric air plasma treatment for potential improvement in the germination of corn (Zea mays) due to enhanced water absorption. The seeds were divided into groups treated at varying durations: 1 second, 2 seconds, and 3 seconds. Wettability and water imbibition increased owing to the seed surface having the potential formation of oxygen and nitrogen-containing functional groups as confirmed present in the plasma by optical emission spectra analysis and to the surface etching revealed in the SEM images. However, only the 1s-treated group exhibited improvement in all germination attributes since longer plasma exposure causes more surface etching, thereby inflicting greater damage to the germ area.

Phase Separation in Charge-Stabilized Colloidal Suspensions: Influence of Nonlinear Screening

description: The phase behavior of charge-stabilized colloidal suspensions is modeled by a combination of response theory for electrostatic interparticle interactions and variational theory for free energies. Integrating out degrees of freedom of the microions (counterions, salt ions), the macroion-microion mixture is mapped onto a one-component system governed by effective macroion interactions. Linear response of microions to the electrostatic potential of the macroions results in a screened-Coulomb (Yukawa) effective pair potential and a one-body volume energy, while nonlinear response modifies the effective interactions [A. R. Denton, \PR E {\bf 70}, 031404 (2004)]. The volume energy and effective pair potential are taken as input to a variational free energy, based on thermodynamic perturbation theory. For both linear and first-order nonlinear effective interactions, a coexistence analysis applied to aqueous suspensions of highly charged macroions and monovalent microions yields bulk separation of macroion-rich and macroion-poor phases below a critical salt concentration, in qualitative agreement with predictions of related linearized theories [R. van Roij, M. Dijkstra, and J.-P. Hansen, \PR E {\bf 59}, 2010 (1999); P. B. Warren, \JCP {\bf 112}, 4683 (2000)]. It is concluded that nonlinear screening can modify phase behavior but does not necessarily suppress bulk phase separation of deionized suspensions.
