Epidemiology of chronic disease and multimorbidity for transgender people living with and without HIV
Creators: name: Rich, Ashleigh
Publisher: name: University of British Columbia
Year: 2021

description: Introduction: Given limited evidence of the epidemiology of chronic disease and multimorbidity for transgender people living with and without HIV, the purpose of this dissertation was to: 1) systematically review chronic disease burden for transgender populations globally; 2) assess methods for identifying transgender people with and without HIV in administrative data, to facilitate investigation of chronic disease-related and other healthcare utilization for this population; and 3) investigate multimorbidity burden for transgender compared to cisgender people living with HIV. Methods: Systematic review methods were used to review and narratively synthesize the empirical literature on chronic disease among transgender populations, globally. Healthcare records were used to develop and validate a computable phenotype to identity transgender people in a large linked provincial administrative dataset. Longitudinal analysis methods were used to examine multimorbidity prevalence and incidence for transgender compared to cisgender people in North America in a large longitudinal HIV cohort collaborative. Key Findings: The literature on chronic disease among transgender populations is focused on mental and sexual health, with sparse attention to chronic physical health, in particular age-related chronic conditions and inflammation-related disease. Identification of transgender people is feasible in administrative health data, with high specificity, concordance with transgender-specific healthcare utilization, and ability to reliably characterize transgender populations in terms of demographics and chronic disease. Transgender people living with HIV had elevated incidence and prevalence of multimorbidity compared to cisgender people living with HIV, though inconsistently over time and without strong evidence of statistically significant differences by gender identity. Conclusions: High quality evidence of chronic conditions among transgender populations is needed; in particular longitudinal, population-based and representative studies with appropriate comparison groups and rigorous measurement of both transgender status and chronic conditions. Development of validated measures for ascertaining transgender status in administrative data is an important contribution given the limited evidence and the methodological challenges in transgender health research. Given evidence of increased burden of multimorbidity for transgender people living with HIV, future research on chronic co- and multimorbidity for transgender populations is warranted with attention to vulnerabilities by racialization and gender, and the role of intervenable disease risk factors such as smoking.

description: Adopting a purely two dimensional relativistic equation for graphene's carriers contradicts the Heisenberg uncertainty principle since it requires setting off-the-surface coordinate of a three-dimensional wavefunction to zero. Here we present a theoretical framework for describing graphene's massless relativistic carriers in accordance with this most fundamental of all quantum principles. A gradual confining procedure is used to restrict the dynamics onto a surface and normal to the surface parts and in the process the embedding of this surface into the three dimensional world is accounted for. As a result an invariant geometric potential arises in the surface part which scales linearly with the Mean curvature and shifts the Fermi energy of the material proportional to bending. Strain induced modification of the electronic properties or "straintronics" is clearly an important field of study in graphene. This opens a venue to producing electronic devices, MEMS and NEMS where the electronic properties are controlled by geometric means and no additional alteration of graphene is necessary. The appearance of this geometric potential also provides us with clues as to how quantum dynamics looks like in the curved space-time of general relativity. In this context, we explore a two-dimensional cross-section of the wormhole geometry realized with graphene as a solid state thought experiment.
High-Accuracy Comparison between the Post-Newtonian and Self-Force Dynamics of Black-Hole Binaries

description: The relativistic motion of a compact binary system moving in circular orbit is investigated using the post-Newtonian (PN) approximation and the perturbative self-force (SF) formalism. A particular gauge-invariant observable quantity is computed as a function of the binary's orbital frequency. The conservative effect induced by the gravitational SF is obtained numerically with high precision, and compared to the PN prediction developed to high order. The PN calculation involves the computation of the 3PN regularized metric at the location of the particle. Its divergent self-field is regularized by means of dimensional regularization. The poles proportional to 1/(d-3) which occur within dimensional regularization at the 3PN order disappear from the final gauge-invariant result. The leading 4PN and next-to-leading 5PN conservative logarithmic contributions originating from gravitational-wave tails are also obtained. Making use of these exact PN results, some previously unknown PN coefficients are measured up to the very high 7PN order by fitting to the numerical self-force data. Using just the 2PN and new logarithmic terms, the value of the 3PN coefficient is also confirmed numerically with very high precision. The consistency of this cross-cultural comparison provides a crucial test of the very different regularization methods used in both SF and PN formalisms, and illustrates the complementarity of these approximation schemes when modelling compact binary systems.

description: Questa ricerca-azione, strutturata in cinque fasi e condotta sull’arco di sette mesi, si prefigge di seguire l’evoluzione del clima di classe (inizialmente problematico) in una classe di II media, in funzione di specifiche scelte pedagogiche fatte dal docente di scienze naturali. Gli interventi attuati dall’insegnante sono principalmente: la proposta della modalità di lavoro collaborativa (lavoro di gruppo) e la progettazione co-evolutiva delle attività, ossia un adattamento dell’approccio didattico ai bisogni formativi ed educativi degli scolari. Gli strumenti di ricerca utilizzati per condurre lo studio sono: il “diario di bordo”, i questionari (a domanda chiusa), i sondaggi (questionari a domanda aperta) e i focus group (piccoli gruppi di discussione). I risultati ottenuti dagli strumenti di rilevazione sopra citati, portano a una constatazione univoca: il clima di classe può migliorare, e questo anche con degli interventi limitati a sole due ore settimanali di insegnamento di scienze, a una condizione: che l’insegnante non segua una programmazione delle lezioni predefinita ma che progetti delle attività che tengano conto delle necessità formative e affettive della persona-allievo e soprattutto che assecondino la costruzione delle conoscenze da parte degli scolari.

For $\barη \to \infty$ we derive the asymptotic Cauchy hitting distribution on $\partial \mathbb{H}^2$ and for small values of $η$ and $\bar η$ we obtain the classical Euclidean Poisson kernel.

What is the Value of Science?

description: In our time, scientific research is positively valued as long as, and to the extent that, it has fruitful implications for the development of technology. This is what we may call “the technological assessment of science”, or “technologism”, for short. I contend that this assessment, so widespread today, stems from a serious error of appreciation, both historically and epistemologically, in ignoring the genuine nature of science—a mistake that can lead, and indeed has been leading for a few decades, to the impoverishment of the scientific spirit and of culture in general.

Modeling TeV gamma-rays from LS 5039: An active OB star at the extreme

description: Perhaps the most extreme examples of "Active OB stars" are the subset of high-mass X-ray binaries -- consisting of an OB star plus compact companion -- that have recently been observed by Fermi and ground-based Cerenkov telescopes like HESS to be sources of very high energy (VHE; up to 30 TeV) gamma-rays. This paper focuses on the prominent gamma-ray source, LS5039, which consists of a massive O6.5V star in a 3.9-day-period, mildly elliptical (e = 0.24) orbit with its companion, assumed here to be a black-hole or unmagnetized neutron star. Using 3-D SPH simulations of the Bondi-Hoyle accretion of the O-star wind onto the companion, we find that the orbital phase variation of the accretion follows very closely the simple Bondi-Hoyle-Lyttleton (BHL) rate for the local radius and wind speed. Moreover, a simple model, wherein intrinsic emission of gamma-rays is assumed to track this accretion rate, reproduces quite well Fermi observations of the phase variation of gamma-rays in the energy range 0.1-10 GeV. However for the VHE (0.1-30 TeV) radiation observed by the HESS Cerenkov telescope, it is important to account also for photon-photon interactions between the gamma-rays and the stellar optical/UV radiation, which effectively attenuates much of the strong emission near periastron. When this is included, we find that this simple BHL accretion model also quite naturally fits the HESS light curve, thus making it a strong alternative to the pulsar-wind-shock models commonly invoked to explain such VHE gamma-ray emission in massive-star binaries.

description: Strain induced band gap deformations of hydrogenated/fluorinated graphene and hexagonal BN sheet have been investigated using first principles density functional calculations. Within harmonic approximation, the deformation is found to be higher for hydrogenated systems than for the fluorinated systems. Interestingly, our calculated band gap deformation for hydrogenated/fluorinated graphene and BN sheets are positive, while those for pristine graphene and BN sheet are found to be negative. This is due to the strong overlap between nearest neighbor π orbitals in the pristine sheets, that is absent in the passivated systems. We also estimate the intrinsic strength of these materials under harmonic uniaxial strain, and find that the in-plane stiffness of fluorinated and hydrogenated graphene are close, but larger in magnitude as compared to those of fluorinated and hydrogenated BN sheet.

description: La sperimentazione si svolge in una sezione di Scuola dell’infanzia di Biasca. Lo scopo di questa ricerca è quello di scoprire se effettuando degli esercizi di rilassamento e di respirazione per un certo periodo di tempo, viene favorita la capacità di concentrazione e attenzione nei bambini di 5/6 anni durante l’esercizio stesso. Inoltre, si va anche a indagare se questi esercizi influiscono positivamente sulla capacità di attenzione e di concentrazione su un compito cognitivo inerente alla comprensione di un testo narrativo. Dai dati raccolti attraverso strumenti di osservazione liberi (diario) e strutturati (tabelle osservative), è stata confermata una maggiore focalizzazione dell’attenzione e uno stato di calma sia durante l’esercizio di rilassamento e di respirazione e sia nel momento subito successivo (l’ascolto della lettura). Non è stato invece osservato un incremento della capacità di attenzione e di concentrazione durante il compito cognitivo. I risultati confermerebbero quindi che gli esercizi di rilassamento e di respirazione porterebbero alcuni benefici ai bambini di età compresa tra i 5 e 6 anni. Relatrice: Paola Iametti.
Control of Cell Proliferation: Is the Default State of Cells Quiescence or Proliferation?

description: The control of cell proliferation in multicellular organisms remains a perennially controversial subject in experimental biology. In this essay, we examine the historical background and the rationale adopted by diverse theoretical and experimental research programs aimed at explaining how and why cells proliferate. We examine the premises that favor the notion that cells in multicellular organisms require direct stimulation from the outside (a task attributed to alleged growth factors) or from the inside (through the elusive action of oncogenes). Our analysis suggests that neither growth factors nor oncogenes directly stimulate the proliferation of cells. Based on evolutionary precedents, theoretical considerations and empirical data we posit instead that proliferation is the default state of all cells; thus, a search for extra- and intra-cellular inhibitory constraints promises to be productive when explaining this basic property of cells within the context of normal and abnormal developmental biology.

description: We study the nature of the confinement phase transition in d=3+1 dimensions in various non-abelian gauge theories with the approach put forward in [1]. We compute an order-parameter potential associated with the Polyakov loop from the knowledge of full 2-point correlation functions. For SU(N) with N=3,...,12 and Sp(2) we find a first-order phase transition in agreement with general expectations. Moreover our study suggests that the phase transition in E(7) Yang-Mills theory also is of first order. We find that it is weaker than for SU(N). We show that this can be understood in terms of the eigenvalue distribution of the order parameter potential close to the phase transition.

The concept of nature between Heraclitus and Prigogine
Creators: name: Bizzarri, Mariano
Publisher: name: Organisms. Journal of Biological Sciences
Year: 2021

description: In the Greek tradition, “physis” denotes both the “nature” (the “essence”) of an entity and its accomplishment, that is to say, its “development”. For example, the embryo is the “essence” of the unfolding organism and, at the same time, the process leading to it. The egg is a symbol of wholeness, but this totality cannot be perceived out of its self-organizing process. In this way, according to Heraclitus, the living being “hides.” Essentially, the Self can only be recognized as an outcome rather than a starting point. This stance, endorsed by Heraclitus and Aristotle, has been left aside by modern scientific research since Bacon’s time when the less noble Stoic inheritance was tacitly assumed. In Stoics’ belief, physis means power (God or otherwise), i.e. the causal principle (causa prima), which is involved in generating any natural process. Having emphasized the “cause”—even in absence of a clear definition of such a concept—the “real process” lost its relevance and its intelligibility was impaired. The description of the process began to be confused with the description of the “entity” (the thing-in-itself), and this representation eventually ended up identifying the “essence” with its (presumed) “primary” causes. This way, natural things and/or processes were re-absorbed into their presumptive causes, missing the true complexity of the natural system.

Context-informed population health knowledge translation : a case study
Creators: name: Shaw, Alexander Graham
Publisher: name: University of British Columbia
Year: 2021

description: Background: Population health evidence suggests a broad range of contexts for the use of knowledge. Researchers identify the need for new services, and they suggest ways to prevent exposure to known harm, often through public policy or structural changes. These suggestions are often beyond the funding and mandates of existing health service organizations. There is still limited guidance to inform knowledge translation when implementation requires collaboration between multiple institutions or where the use of knowledge calls for new resources or infrastructure. Method: This research investigates context-informed knowledge translation to improve population health. It collects and analyzes interview data from experienced knowledge translation practitioners in a case study organization that seeks to promote universal programs and public policy to improve health at a population level. Knowledge translation is examined at two levels, first at an organizational level and then in two sub cases that represent divergent knowledge products and different contextual barriers and opportunities. Qualitative analysis is used to investigate the range of approaches used and the rationale for the use of specific approaches in different contexts. Discussion: Findings suggest that there are identifiable links between the nature of contextual challenges and the approaches used in the case study. Challenges for knowledge translation can be conceptually divided into three categories: 1. Ensuring reach and understanding, 2. Ensuring capacity for implementation, and 3. Ensuring that those positioned to act effectively on the knowledge are motivated to do so. Findings suggested that the categories of approach used by knowledge translation practitioners correspond with the nature of identified challenges: exchange and transfer of information to build awareness and understanding, processed focused approaches to build implementation capacity, and strategic approaches to persuade or motivate uptake. Findings operationalize knowledge, context, and facilitation in ways that can be used in further study of conditions where knowledge translation may need to build capacity or motivation to advance the use of reliable knowledge. Practitioners can use the proposed categories to identify context specific challenges and can then draw from the hierarchically structured menu of approaches to build theories of change that can plausibly address them.

description: In this review we show that the multi-particle scattering amplitudes in N=4 SYM at large Nc and in the multi-Regge kinematics for some physical regions have the high energy behavior appearing from the contribution of the Mandelstam cuts in the complex angular momentum plane of the corresponding t-channel partial waves. These Mandelstam cuts or Regge cuts are resulting from gluon composite states in the adjoint representation of the gauge group SU(Nc). In the leading logarithmic approximation (LLA) their contribution to the six point amplitude is in full agreement with the known two-loop result. The Hamiltonian for the Mandelstam states constructed from n gluons in LLA coincides with the local Hamiltonian of an integrable open spin chain. We construct the corresponding wave functions using the integrals of motion and the Baxter-Sklyanin approach.

description: Recently Yampol'skii et al. [Phys. Rev. A v.82, 032511 (2010)] advocated that Lifshitz theory is not applicable when the characteristic wavelength of the fluctuating electromagnetic field, responsible for the thermal correction to the Casimir force, is larger than the size of the metal test bodies. It was claimed that this is the case in experiments which exclude Lifshitz theory combined with the Drude model. We calculate the wavelengths of the evanescent waves giving the dominant contribution to the thermal correction and we find that they are much smaller than the sizes of the test bodies. The opposite conclusion obtained by the authors arose from a confusion between propagating and evanescent waves.

description: Acquiring a systemic perspective on epidemic events is mandatory in an age in which such events are rapidly growing in both number and spatial distribution. In this work we describe the human/virus interaction through the ‘deep time’ of evolution. We show how ancient epidemics shaped animal and human biology influencing basic traits like multi-cellularity, immunity and cancer. Furthermore, on a much shorter time scale, we focus on the role played by globalization and anthropogenic environmental deterioration in the growing menace of recurring pandemics.

description: We study the thermal escape problem in the low damping limit. We find that finiteness of the barrier is crucial for explaining the thermal activation results. In this regime low barrier non-equilibrium corrections to the usual theories become necessary. We propose a simple theoretical extension accounting for these non-equilibrium processes which agrees numerical results. We apply our theory to the understanding of switching current curves in underdamped Josephson junctions.

description: Asymmetric transmission of circularly polarized waves is a well-established property of lossy, anisotropic, two-dimensionally chiral patterns. Here we show that asymmetric transmission can be observed for oblique incidence onto any lossy periodically structured plane. Our results greatly expand the range of natural and artificial materials in which directionally asymmetric transmission can be expected making it a cornerstone electromagnetic effect rather than a curiosity of planar chiral metamaterials. Prime candidates for asymmetric transmission at oblique incidence are rectangular arrays of plasmonic spheres or semiconductor quantum dots, lossy double-periodic gratings and planar metamaterial structures.

description: Nobel Prize winner, Jennifer Doudna, and Samuel Sternberg survey recent advances in a pioneering area of molecular biology. In an accessible and elegant style, the authors present the successes and challenges of a new DNA-modifying technique: CRISPR. They transmit their emotions of discovery, passion for research, and intellectual audacity. While greatly admiring the technical skills of the authors, who are among the best researchers in the field, this review critically stresses the limits of their experimental practices, namely: a vague or incomplete theoretical frame; often unreachable genetic targets; off-target effects; prior failures to deliver by other forms of genetic manipulation, and, finally, the intrinsic unpredictability of many phenotypic consequences of such a powerful technique. Due to these concerns, the authors’ approach to organisms and Evolution is questioned with the purpose to generate an open debate.

description: Solar filaments show the position of large scale polarity inversion lines and are used for the reconstruction of large-scale solar magnetic field structure on the basis of Hα synoptic charts for the periods when magnetographic measurements were not available. Sometimes crossing filaments are seen in Hα filtergrams. We analyze daily Hα filtergrams from the archive of Big Bear Solar Observatory for the period of 1999-2003 to find crossing and interacting filaments. A number of examples are presented and filament patterns are compared with photospheric magnetic field distributions. We have found that all crossing filaments reveal quadrupolar magnetic configurations of the photospheric field and presume the presence of null points in the corona.

Heavy traffic analysis for EDF queues with reneging

description: This paper presents a heavy-traffic analysis of the behavior of a single-server queue under an Earliest-Deadline-First (EDF) scheduling policy in which customers have deadlines and are served only until their deadlines elapse. The performance of the system is measured by the fraction of reneged work (the residual work lost due to elapsed deadlines) which is shown to be minimized by the EDF policy. The evolution of the lead time distribution of customers in queue is described by a measure-valued process. The heavy traffic limit of this (properly scaled) process is shown to be a deterministic function of the limit of the scaled workload process which, in turn, is identified to be a doubly reflected Brownian motion. This paper complements previous work by Doytchinov, Lehoczky and Shreve on the EDF discipline in which customers are served to completion even after their deadlines elapse. The fraction of reneged work in a heavily loaded system and the fraction of late work in the corresponding system without reneging are compared using explicit formulas based on the heavy traffic approximations. The formulas are validated by simulation results.

Dusty Disks around White Dwarfs I: Origin of Debris Disks

description: A significant fraction of the mature FGK stars have cool dusty disks at least an orders of magnitudes brighter than the solar system's outer zodiacal light. Since such dusts must be continually replenished, they are generally assumed to be the collisional fragments of residual planetesimals analogous to the Kuiper Belt objects. At least 10% of solar type stars also bear gas giant planets. The fraction of stars with known gas giants or detectable debris disks (or both) appears to increase with the stellar mass. Here, we examine the dynamical evolution of systems of long-period gas giant planets and residual planetesimals as their host stars evolve off the main sequence, lose mass, and form planetary nebula around remnant white dwarf cores. The orbits of distant gas giant planets and super-km-size planetesimals expand adiabatically. During the most intense AGB mass loss phase, sub-meter-size particles migrate toward their host stars due to the strong hydrodynamical drag by the intense stellar wind. Along their migration paths, gas giant planets capture and sweep up sub-km-size planetesimals onto their mean-motion resonances. These planetesimals also acquire modest eccentricities which are determined by the mass of the perturbing planets, the rate and speed of stellar mass loss. The swept-up planetesimals undergo disruptive collisions which lead to the production of grains with an extended size range. The radiation drag on these particles is ineffective against the planets' resonant barrier and they form 30-to-150-AU-sizes rings which can effective reprocess the stellar irradiation in the form of FIR continuum. We identify the recently discovered dust ring around the white dwarf WD 2226-210 at the center of the Helix nebula as a prototype of such disks and suggest such rings may be common.

description: Introduction Nature has provided living bodies with extraordinary active reparative mechanisms. Besides these biological processes anatomical structures are designed to protect life against external injuries. A series of these protective systems in the upper limb are described. Material and Methods From 2009 to 2017, 864 fresh frozen cadaveric upper limbs have been dissected from the axilla to the fingers into the program of the Italian Hand Society surgical anatomy dissection course. Results Arrangement of anatomical structures in the upper limb is proven to protect major life supporting organs. Conclusions External injuries affecting the upper limb may cause damage to many important structures with severe consequences on function. The layout of these structures and the relations within them is organized to preserve life at any functional cost.

description: In this paper, we show that the existence of Sasakian-Einstein metrics is closely related to the properness of corresponding energy functionals. Under the condition that admitting no nontrivial Hamiltonian holomorphic vector field, we prove that the existence of Sasakian-Einstein metric implies a Moser-Trudinger type inequality. At the end of this paper, we also obtain a Miyaoka-Yau type inequality in Sasakian geometry.
