Low-dimensional carbon allotropes: an electron microscopy investigation

description: The research reported in this manuscript concerns the structural characterization of graphene membranes and single-walled carbon nanotubes (SWCNTs). The experimental investigation was performed using a wide range of transmission electron microscopy (TEM) techniques, from conventional imaging and diffraction, to advanced interferometric methods, like electron holography and Geometric Phase Analysis (GPA), using a low-voltage optical set-up, to reduce radiation damage in the samples. Electron holography was used to successfully measure the mean electrostatic 
potential of an isolated SWCNT and that of a mono-atomically thin graphene crystal. The high accuracy achieved in the phase determination, made it possible to measure, for the ﬁrst time, the valence-charge redistribution induced by the lattice curvature in an individual SWCNT. A novel methodology for the 3D reconstruction of the waviness of a 2D crystal membrane has been developed. Unlike other available TEM reconstruction techniques, like tomography, this new one requires processing of just a single HREM 
micrograph. The modulations of the inter-planar distances in the HREM image are measured using Geometric Phase Analysis, and used to recover the waviness of the crystal. The method was applied to the case of a folded FGC, and a height variation of 0.8 nm of the surface was successfully determined with nanometric lateral resolution. The adhesion of SWCNTs to the surface of graphene was studied, mixing shortened SWCNTs of different chiralities and FGC membranes. The spontaneous atomic match of the two lattices was directly imaged using HREM, and we found that graphene membranes act as tangential nano-sieves, preferentially grafting achiral tubes to their surface.
Development of screening assays to test novel integrin antagonists in allergic inflammation

description: Aim of the research: to develop a prototype of homogeneous high-throughput screening (HTS) for identification of novel integrin antagonists for the treatment of ocular allergy and
to better understand the mechanisms of action of integrin-mediated levocabastine antiallergic action.
Results: This thesis provides evidence that adopting scintillation proximity assay (SPA) levocabastine (IC50=406 mM), but not the first-generation antihistamine chlorpheniramine, displaces [125I]fibronectin (FN) binding to human a4b1 integrin. This result is supported by flow cytometry analysis, where levocabastine antagonizes the binding of a primary antibody to integrin a4 expressed in Jurkat E6.1 cells. Levocabastine, but not chlorpheniramine, binds to a4b1 integrin and prevents eosinophil adhesion to VCAM-1, FN or human umbilical vein endothelial cells (HUVEC) cultured in vitro. Similarly, levocabastine affects aLb2/ICAM-1-mediated adhesion of Jurkat E6.1 cells. Analyzing the supernatant of TNF-a-treated (24h) eosinophilic cells (EoL-1), we report that levocabastine reduces the TNF-a-induced release of the cytokines IL-12p40, IL-8 and VEGF. Finally, in a model of allergic conjunctivitis, levocastine eye drops (0.05%) reduced the clinical aspects of the early and late phase reactions and the conjunctival expression of a4b1 integrin by reducing infiltrated eosinophils.
Conclusions: SPA is a highly efficient, amenable to automation and robust binding assay to screen novel integrin antagonists in a HTS setting. We propose that blockade of integrinmediated cell adhesion might be a target of the anti-allergic action of levocabastine and may
play a role in preventing eosinophil adhesion and infiltration in allergic conjunctivitis.

Morphogenesis of follicular epithelium

function of von Hippel-Lindau tumour suppressor gene

description: During my PhD I have been involved in several projects regarding the morphogenesis of the follicular epithelium, such as the analysis of the pathways that correlate follicular epithelium patterning and eggshell genes expression. Moreover, I used the follicular epithelium as a model system to analyze the function of the Drosophila homolog of the human von Hippel-Lindau (d-VHL) during oogenesis, in order to gain insight into the role of h-VHL for the pathogenesis of VHL disease. h-VHL is implicated in a variety of processes and there is now a greater appreciation of HIF-independent h-VHL functions that are relevant to tumour development, including maintenance and organization of the primary cilium, maintenance of the differentiated phenotype in renal cells and regulation of epithelial-mesenchymal transition. However, the function of h-VHL gene during development has not been fully understood. It was previously shown that d-VHL down-regulates the motility of tubular epithelial cells (tracheal cells) during embryogenesis. Epithelial morphogenesis is important for organogenesis and pivotal for carcinogenesis, but mechanisms that control it are poorly understood. The Drosophila follicular epithelium is a genetically tractable model to understand these mechanisms in vivo. Therefore, to examine whether d-VHL has a role in epithelial morphogenesis and maintenance, I performed genetic and molecular analyses by using in vivo and in vitro approaches. From my analysis, I determined that d-VHL binds to and stabilizes microtubules. Loss of d-VHL depolymerizes the microtubule network during oogenesis, leading to a possible deregulation in the subcellular trafficking transport of polarity markers from Golgi apparatus to the different domains in which follicle cells are divided. The analysis carried out has allowed to establish a significant role of d-VHL in the maintenance of the follicular epithelium integrity.

description: While drug-resistance exists in a wide range of clinically important microorganisms, new drug development has significantly lagged behind the need. We are directly addressing this gap in antimicrobial development by synthesizing a novel class of antimicrobials that are not inactivated by the microbial beta-lactamases. To date, we have synthesized cadres of compounds with demonstrated good activity (minimum inhibitory (MIC) and minimum bactericidal concentration, MBC, <15 ug/ml) against Mycobacterium tuberculosis (Mtb) or Moraxella catarrhalis (M.cat.). The focus of my research is to prepare a second generation of these drugs by building a library of compounds containing fluorinated derivatives. The position and multitude of the fluorine atoms in the compounds' scaffold is expected to improve overall efficacy of these compounds. In addition, preparation of compounds with differently substituted carbamyl groups has been accomplished. The Structure Activity Relationship (SAR) of these two types of compounds will be presented.

description: The Orlik-Solomon algebra is the cohomology ring of the complement of a hyperplane arrangement A in C^n; it is the quotient of an exterior algebra E(V) on |A| generators. Orlik and Terao introduced a commutative analog S(V)/I of the Orlik-Solomon algebra to answer a question of Aomoto and showed the Hilbert series depends only on the intersection lattice L(A). Motivated by topological considerations, Falk and Randell introduced the property of 2-formality; we study the relation between 2-formality and the Orlik-Terao algebra. Our main result is a necessary and sufficient condition for 2-formality in terms of the quadratic component I_2 of the Orlik-Terao ideal I: 2-formality is determined by the tangent space T_p(V(I_2)) at a generic point p.

description: Introduction:Persistent Hyperparathyroidism after transplantation (HPT),bone disease and vertebral fractures are an important clinical problem in renal transplant patients. Several factors such as renal osteodystrophy, immunosuppressive therapy, deficit/insufficiency Vitamin D may contribute to that.In literature are described different  percentages of  HPT, vertebral fractures and Osteoporosis/Osteopenia that may be due to the different therapy and to the different employ of steroid. We analyzed 90 patients who received a renal graft between 2005 e 2010. Patients and Methods: 44 male and 46 female. Average age 52,2± 10,1 years, follow-up 31,3±16,6 months, time on dialysis 37±29,6 months. Patients who had  creatinine level greater than 2,5 mg/dl were excluded. Immunosuppressive therapy was based on basiliximab, steroids (1.6 to 2 mg/kg/day progressively reduced to 5 mg/day after 45 days from the transplantation) in all patients +  calcineurin inhibitor+ mycophenolate mophetil/mycophenolic acid in 88,8% of patients or Everolimus± calcineurin inhibitor in the others. Patients were studied with X-ray of the spine, dual-energy-X-ray, PTH, 25(OH)VitD. Results: 41,1% had HPT; 41,1% had osteopenia at femoral neck and 36,7% at vertebral column; 16,7% had osteoporosis at femoral neck and 15,6% at vertebral column. 10 patients (11%) had vertebral fractures. Patients with normal bone mineral density, compared to those with osteoporosis/osteopenia, are  more younger (average age 46,4±11,7 years vs 54.3±8,6); they have spent less time on dialysis (26,5±14,8 months vs 40,7±32,6) and they have values of 25(OH)VitD higher (22,1±7,6  ng/ml vs 17,8±8,5). Patients with vertebral fractures have values of 25(OH)VitD lowest (14,1±6,4 ng/ml vs 19,7±8,5) and they had transplant since more time (29,1±16,2 vs 48,1±8,7 months). 
There is a significant correlation between HPT and PTH pre transplantation; HPT and levels of VitD (p<0,05) Conclusion: Prevention of Bone disease and vertebral fractures after renal transplant includes: a)treatment before transplantation b)supplementation of vitamin D with cholecalciferol or calcidiol c)shorten the dialysis time.

description: A multi-channel MAC seems to be an interesting approach for improving network throughput by multiplexing transmissions over orthogonal channels. In particular, Molecular MAC has recently proposed to modify the standard IEEE 802.11 DCF access method to use dynamic channel switching for efficient packet forwarding over multiple hops. However, this MAC layer requires role and channel assignment to nodes: some of them use a static channel, while others dynamically switch to neighbor channels on-demand. To assign roles and channels, we extend the notion of the Weakly Connected Dominating Set, the structure already used in clustering. More precisely, we adapt the WCDS structure and introduce new constraints to define what we call a reversible WCDS (r-WCDS), which is particularly suitable for wireless mesh networks operating under Molecular MAC. We propose a divide-and-conquer scheme that partitions the network into clusters with one leader per cluster solving a MILP formulation to assign roles in its cluster. By appropriately defining the roles at the border of clusters, we maintain global connectivity in the r-wcds. Finally, our simulations show that the performance of the propose scheme is close to a centralized algorithm.
Occupational Mobility: Theory and Estimation for Italy

description: This paper presents a model where intergenerational occupational mobility is the joint outcome of three main determinants: income incentives, equality of opportunity and changes in the composition of occupations. The model rationalizes the use of transition matrices to measure mobility, which allows for the identification of asymmetric mobility patterns and for the formulation of a specific mobility index for each determinant. Italian children born in 1940-1951 had a lower mobility with respect to those born after 1965. The steady mobility for children born after 1965, however, covers a lower structural mobility in favour of upper-middle classes and a higher downward mobility from upper-middle classes. Equality of opportunity was far from the perfection but steady for those born after 1965. Changes in income incentives instead played a major role, leading to a higher downward mobility from upper-middle classes and lower upward mobility from the lower class.

description: Microalgae are sun - light cell factories that convert carbon dioxide to biofuels, foods, feeds, and other bioproducts. The concept of microalgae cultivation as an integrated system in wastewater treatment has optimized the potential of the microalgae - based biofuel production. These microorganisms contains lipids, polysaccharides, proteins, pigments and other cell compounds, and their biomass can provide different kinds of biofuels such as biodiesel, biomethane and ethanol. The algal biomass application strongly depends on the cell composition and the production of biofuels appears to be economically convenient only in conjunction with wastewater treatment. The aim of this research thesis was to investigate a biological wastewater system on a laboratory scale growing a newly isolated freshwater microalgae, Desmodesmus communis, in effluents generated by a local wastewater reclamation facility in Cesena (Emilia Romagna, Italy) in batch and semi - continuous cultures. This work showed the potential utilization of this microorganism in an algae - based wastewater treatment; Desmodesmus communis had a great capacity to grow in the wastewater, competing with other microorganisms naturally present and adapting to various environmental conditions such as different irradiance levels and nutrient concentrations. The nutrient removal efficiency was characterized at different hydraulic retention times as well as the algal growth rate and biomass composition in terms of proteins, polysaccharides, total lipids and total fatty acids (TFAs) which are considered the substrate for biodiesel production. The biochemical analyses were coupled with the biomass elemental analysis which specified the amount of carbon and nitrogen in the algal biomass. Furthermore photosynthetic investigations were carried out to better correlate the environmental conditions with the physiology responses of the cells and consequently get more information to optimize the growth rate and the increase of TFAs and C/N ratio, cellular compounds and biomass parameter which are fundamental in the biomass energy recovery.

description: Let F1 and F2 be independent copies of correlated fractal percolation, with Hausdorff dimensions dimH(F1) and dimH(F2). Consider the following question: does dimH(F1)+dimH(F2)>1 imply that their algebraic difference F1-F2 will contain an interval? The well known Palis conjecture states that `generically' this should be true. Recent work by Kuijvenhoven and the first author (arXiv:0811.0525) on random Cantor sets can not answer this question as their condition on the joint survival distributions of the generating process is not satisfied by correlated fractal percolation. We develop a new condition which permits us to solve the problem, and we prove that the condition of (arXiv:0811.0525) implies our condition. Independently of this we give a solution to the critical case, yielding that a strong version of the Palis conjecture holds for fractal percolation and correlated fractal percolation: the algebraic difference contains an interval almost surely if and only if the sum of the Hausdorff dimensions of the random Cantor sets exceeds one.

description: My Doctorate Research has been focused on the evaluation of the pharmacological activity of a
natural extract of chestnut wood (ENC) towards the cardiovascular and gastrointestinal system and
on the identification of the active compounds.
The ENC has been shown to contain more than 10% (w/w) of phenolic compounds, of
which tannins as Vescalgin and Castalgin are the more representative.
ENC cardiovascular effects have been investigated in guinea pig cardiac preparations; furthermore
its activity has been evalueted in guinea pig aorta strips.
ENC induced transient negative chronotropic effect in isolated spontaneously beating right atria and
simultaneously positive inotropic effect in left atria driven at 1 Hz. Cardiac cholinergic receptors
are not involved in the negative chronotropic effect and positive inotropic effects are not related to
adrenergic receptors. In vascular smooth muscle, natural extract of chestnut did not significantly
change the contraction induced by potassium (80 mM) or that induced by noradrenaline (1μM).
In guinea pig ileum, ENC reduced the maximum response to carbachol in a concentrationdependent
manner and behaved as a reversible non competitive antagonist. In guinea pig ileum, the
antispasmodic activity of ENC showed a significant antispasmodic activity against a variety of
different spasmogenic agents including histamine, KCl, BaCl2. In guinea pig proximal colon,
stomach and jejunum, ENC reduced the maximum response to carbachol in a concentrationdependent
manner and behaved as a reversible non competitive antagonist.
ENC contracted gallbladder guinea pig in a reversible and concentration-dependent manner. This
effect does not involve cholinergic and cholecystokinin receptors and it is reduced by nifedipine.
ENC relaxed Oddi sphincter smooth muscle. The cholecystokinetic and Oddi sphincter relaxing
activities occurred also in guinea pigs fed a lithogenic diet. The cholecystokinetic occurred also in
human gallbladder. The Fractionation of the extract led to the identification of the active fraction.

description: Speeding the VO2 kinetics results in a reduction of the O2 deficit.
Two factors might determine VO2 kinetics: oxygen delivery to muscle (Tschakovsky and Hughson 1999) and a muscle 'metabolic inertia' (Grassi et al. 1996). 
 Therefore, in study 1 we investigated VO2 kinetics and cardiovascular system adaptations during step exercise transitions in different regions of the moderate domain.
In study 2 we investigated muscle oxygenation and cardio-pulmonary adaptations during step exercise tests before, after and over a period of training. 

Study 1 methods:  Seven subjects (26 ± 8 yr; 176 ± 5 cm; 69 ± 6 kg) performed 4 types of step transition from rest  (0-50W; 0-100W) or elevate baseline (25-75W; 25-125W). GET and VO2max were assessed before testing.  O2 uptake and   were measured during testing.

Study 2 methods: 10 subjects (25 ± 4 yr; 175 ± 9 cm; 71 ± 12 kg) performed a step transition test (0 to 100 W) before, after and during 4 weeks of endurance training (ET). VO2max and GET were assessed before and after of ET (40 minutes, 3 times a week, 60%  O2max). VO2 uptake, Q and deoxyheamoglobin were measured during testing.

Study 1 results: VO2 τ and the functional gain were slower in the upper regions of the moderate domain. Q increased more abruptly during rest to work condition.  Q τ was faster than  VO2 τ for each exercise step.

Study 2 results:   VO2 τ  became faster after ET (25%) and particularly after 1 training session (4%).  Q kinetics changed after 4 training sessions nevertheless it was always faster than  VO2 τ.  An attenuation in ∆[HHb] /∆VO2 was detectible.


Conclusion: these investigations suggest that muscle fibres recruitment exerts a influence on the VO2 response within the moderate domain either during different forms of step transition or following ET.

description: Superlattice of spin vortices has been proposed in an earlier article as an alternative to the stripe interpretation of spin modulations in 1/8-doped lanthanum cuprates. The present article addresses several additional characteristics of the spin vortex lattice, namely: (i) the nature of extended charge states; (ii) the position of neutron spin peaks as a function of doping; and (iii) the absence of higher order spin harmonics. All these characteristics afford straightforward connection to the experimental results produced by angle-resolved photoemission spectroscopy, resistivity measurements, and neutron scattering.

description: We define an integral of real-valued functions with respect to a measure that takes its values in the extended positive cone of a partially ordered vector space $E$. The monotone convergence theorem, Fatou's lemma, and the dominated convergence theorem are established; the analogues of the classical ${\mathcal L}^1$- and ${\mathrm L}^1$-spaces are investigated. The results extend earlier work by Wright and specialise to those for the Lebesgue integral when $E$ equals the real numbers. The hypothesis on $E$ that is needed for the definition of the integral and for the monotone convergence theorem to hold ($σ$-monotone completeness) is a rather mild one. It is satisfied, for example, by the space of regular operators between a directed partially ordered vector space and a $σ$-monotone complete partially ordered vector space, and by every JBW-algebra. Fatou's lemma and the dominated convergence theorem hold for every $σ$-Dedekind complete space. When $E$ consists of the regular operators on a Banach lattice with an order continuous norm, or when it consists of the self-adjoint elements of a strongly closed complex linear subspace of the bounded operators on a complex Hilbert space, then the finite measures as in the current paper are precisely the strongly $σ$-additive positive operator-valued measures. When $E$ is a partially ordered Banach space with a closed positive cone, then every positive vector measure is a measure in our sense, but not conversely. Even when a measure falls into both categories, the domain of the integral as defined in this paper can properly contain that of any reasonably defined integral with respect to the vector measure using Banach space methods.

description: The results of a long-established investigation into pupal transpiration are used as a rudimentary data set. These data are then generalised to all temperatures and humidities by invoking the property of multiplicative separability, as well as by converting established relationships in terms of constant humidity at fixed temperature, to alternatives in terms of a calculated water loss. In this way a formulation which is a series of very simple, first order, ordinary differential equations is devised. The model is extended to include a variety of Glossina species using their relative surface areas, their relative pupal and puparial loss rates and their different 4th instar excretions. The resulting computational model calculates total, pupal water loss, consequent mortality and emergence. Remaining fat reserves are a more tenuous result. The model suggests that, while conventional wisdom is often correct in dismissing variability in transpiration-related pupal mortality as insignificant, the effects of transpiration can be profound under adverse conditions and for some species, in general. The model demonstrates how two gender effects, the more significant one at the drier extremes of tsetse fly habitat, might arise. The agreement between calculated and measured critical water losses suggests very little difference in the behaviour of the different species.

description: We generalise the Riesz representation theorems for positive linear functionals on $\mathrm{C}_{\mathrm c}(X)$ and $\mathrm{C}_{\mathrm 0}(X)$, where $X$ is a locally compact Hausdorff space, to positive linear operators from these spaces into a partially ordered vector space $E$. The representing measures are defined on the Borel $σ$-algebra of $X$ and take their values in the extended positive cone of $E$; the corresponding integrals are order integrals. We give explicit formulas for the values of the representing measures at open and at compact subsets of $X$. Results are included where the space $E$ need not be a vector lattice, nor a normed space. Representing measures exist for positive linear operators into Banach lattices with order continuous norms, into the regular operators on a KB-space, into the self-adjoint linear operators in a weakly closed complex linear subspace of the bounded linear operators on a complex Hilbert space, and into JBW-algebras.

description: A stochastic model of electric field-driven polarization reversal in orthorhombic ferroelectrics is advanced, providing a description of their temporal electromechanical response. The theory accounts for all possible parallel and sequential switching events. Application of the model to the simultaneous measurements of polarization and strain kinetics in a lead-free orthorhombic (K,Na)NbO3-based ferroelectric ceramic over a wide timescale of 7 orders of magnitude allowed identification of preferable polarization switching paths, fractions of individual switching processes, and their activation fields. Particularly, the analysis revealed substantial contributions of coherent non-180° switching events, which do not cause macroscopic strain and thus mimic 180° switching processes.

Descriptive study of the mobile instructional resource centre project : August 1973 to March 1974
Creators: name: Gobert, Robert Charles
Publisher: name: University of British Columbia

description: The P.A. Woodward Mobile Instructional Resource Centre Project (MIRC) was a motorized educational delivery system used by the Division of Continuing Education in the Health Sciences at the University of British Columbia to provide learning opportunities for health professionals in their home communities. This study describes the project and analyzes its role in continuing education in the health field for those resident in the rural areas served by the project. The MIRC was a highway bus converted into a mobile continuing education facility containing three audio visual learning stations and over 1300 audio visual learning programs. Operated by a graduate adult education student, the MIRC visited 17 rural British Columbia communities between August 1, 1973 and March 31, 1974. During this period, data were obtained from 521 participants in 11 health professions and from 136 non-participants in seven health professions. Participation rates in the MIRC project were higher than those in other programs provided by the Division of Continuing Education in the Health Sciences during the same period whether examined by community or by professional category. MIRC participation rates were significantly higher among those professions for whom the Division provided other programs than they were among those for whom it did not. Participation rates were not related to distance from Vancouver but were higher for communities with smaller local hospitals. The MIRC project appears to have served a different set of individuals than did other Division programs. Direct costs were approximately four times as high but the expenses borne by participants and their employers were not considered. Participants and non-participants differed significantly with respect to sex, profession, location of employment, and number of professional books read. Reactions to the project, measured on a five-point scale, were favorable over-all. Significant differences among the professional groups were observed on two items and among various communities on all items. Reaction scores were not significantly related to participation rates or to the size of communities, but were higher in communities nearer Vancouver. By assigning ranks to eight alternative educational delivery systems, the respondents as a whole indicated that they preferred an audio-visual learning station in a hospital or in the MIRC project. Participants whose rankings were not related to those of non-participants preferred these same two systems. Non-participants preferred using a hospital library or attending courses outside their communities. Among the reasons given for not participating, most did not suggest ways in which the project could be altered to improve participation. It was concluded that the MIRC project is an acceptable and effective system for delivering continuing education opportunities to health professionals in rural British Columbia.

description: We use observations of the radial profiles of the mass surface density of total, Sigma_g, and molecular, Sigma_H2, gas, rotation velocity and star formation rate surface density, Sigma_sfr, of the molecular dominated regions of 12 disk galaxies from Leroy et al. to test several star formation laws: a "Kennicutt-Schmidt power law", Sigma_sfr=A_g Sigma_{g,2}^{1.5}$; a "Constant molecular law", Sigma_sfr = A_H2 Sigma_{H2,2}; the "Turbulence-regulated laws" of Krumholz & McKee (KM) and Krumholz, McKee & Tumlinson (KMT), a "Gas-Omega law", Sigma_sfr = B_Omega Sigma_g Omega; and a shear-driven "GMC collisions law", Sigma_sfr = B_CC Sigma_g Omega (1 - 0.7beta), where beta is d ln v_circ / d ln r. We find the constant molecular law, KMT turbulence law and GMC collision law are the most accurate, with an rms error of a factor of 1.5 if the normalization constants are allowed to vary between galaxies. Of these three laws, the GMC collision law does not require a change in physics to account for the full range of star formation activity seen from normal galaxies to circumnuclear starbursts. A single global GMC collision law with B_CC=8.0x10^{-3}, i.e. a gas consumption time of 20 orbital times for beta=0, yields an rms error of a factor of 1.8.

Functional-renormalization-group approach to strongly coupled Bose-Fermi mixtures in two dimensions

description: We study theoretically the phase diagram of strongly coupled two-dimensional Bose-Fermi mixtures interacting with attractive short-range potentials as a function of the particle densities. We focus on the limit where the size of the bound state between a boson and a fermion is small compared to the average interboson separation and develop a functional-renormalization-group approach that accounts for the bound-state physics arising from the extended Fröhlich Hamiltonian. By including three-body correlations we are able to reproduce the polaron-to-molecule transition in two-dimensional Fermi gases in the extreme limit of vanishing boson density. We predict frequency- and momentum-resolved spectral functions and study the impact of three-body correlations on quasiparticle properties. At finite boson density, we find that when the bound-state energy exceeds the Fermi energy by a critical value, the fermions and bosons can form a fermionic composite with a well-defined Fermi surface. These composites constitute a Fermi sea of dressed Feshbach molecules in the case of ultracold atoms while in the case of atomically thin semiconductors a trion liquid emerges. As the boson density is increased further, the effective energy gap of the composites decreases, leading to a transition into a strongly correlated phase where polarons are hybridized with molecular degrees of freedom. We highlight the universal connection between two-dimensional semiconductors and ultracold atoms and we discuss perspectives for further exploring the rich structure of strongly coupled Bose-Fermi mixtures in these complementary systems.

description: We study the impact of a non-vanishing (positive) cosmological constant on the innermost and outermost stable circular orbits (ISCOs and OSCOs, respectively) within massive gravity in four dimensions. The gravitational field generated by a point-like object within this theory is known, generalizing the usual Schwarzschild--de Sitter geometry of General Relativity. In the non-relativistic limit, the gravitational potential differs by the one corresponding to the Schwarzschild--de Sitter geometry by a term that is linear in the radial coordinate with some prefactor $γ$, which is the only free parameter. Starting from the geodesic equations for massive test particles and the corresponding effective potential, we obtain a polynomial of fifth order that allows us to compute the innermost and outermost stable circular orbits. Next, we numerically compute the real and positive roots of the polynomial for several different structures (from the hydrogen atom to stars and globular clusters to galaxies and galaxy clusters) considering three distinct values of the parameter $γ$, determined using physical considerations, such as galaxy rotation curves and orbital precession. Similarly to the Kottler spacetime, both ISCOs and OSCOs appear. Their astrophysical relevance as well as the comparison with the Kottler spacetime are briefly discussed.

description: We study a class of non-local, purely gravitational models which have the correct structure to reproduce the leading infrared logarithms of quantum gravitational back-reaction during the inflationary regime. These models end inflation in a distinctive phase of oscillations with slight and short violations of the weak energy condition and should, when coupled to matter, lead to rapid reheating. By elaborating this class of models we exhibit one that has the same behaviour during inflation, goes quiescent until the onset of matter domination, and induces a small, positive cosmological constant of about the right size thereafter.

Systematic Review of HIPAA and Privacy Regulations in Correctional Facilities with a Focus on HIV-Positive Inmates
Creators: name: Ivy Zeng
Publisher: name: Zenodo
Year: 2023

description: The Health Insurance Portability and Accountability Act is a federal law that was signed into law in 1996. The purpose of this is to ensure the safety and privacy of sensitive health information from being disclosed without the knowledge of the patient. This is also made true in correctional facilities. Inmates have the same HIPAA rights as civilians, like the minimum necessary standard. Covered entities under HIPAA include any health plan, healthcare clearinghouse, or healthcare provider communicating Protected Health Information (PHI) electronically. This paper will review the privacy regulations in correctional facilities and the stigma surrounding HIV. I describe how the minimum necessary utilizes protected health information for intended purposes and under what circumstances law enforcement can receive protected health information. In addition, I will focus on the stigma surrounding HIV-positive inmates and how the segregation of HIV-positive inmates is a breach of confidentiality. Methods used are MeSH search on the National Library of Medicine to identify papers that present data on privacy regulations in prison. We will also use a public dataset on staff stigma attitudes surrounding HIV in correctional facilities and create pie charts displaying results.
Quasi-symmetries in complex networks: a dynamical model approach

description: The existence of symmetries in complex networks has a significant effect on network dynamic behaviour. Nevertheless, beyond topological symmetry, one should consider the fact that real-world networks are exposed to fluctuations or errors, as well as mistaken insertions or removals. Therefore, the resulting approximate symmetries remain hidden to standard symmetry analysis - fully accomplished by discrete algebra software. There have been a number of attempts to deal with approximate symmetries. In the present work we provide an alternative notion of these weaker symmetries, which we call `quasi-symmetries'. Differently from other definitions, quasi-symmetries remain free to impose any invariance of a particular network property and they are obtained from the phase differences at the steady-state configuration of an oscillatory dynamical model: the Kuramoto-Sakaguchi model. The analysis of quasi-symmetries unveils otherwise hidden real-world networks attributes. On the one hand, we provide a benchmark to determine whether a network has a more complex pattern than that of a random network with regard to quasi-symmetries, namely, if it is structured into separate quasi-symmetric groups of nodes. On the other hand, we define the `dual-network', a weighted network (and its corresponding binnarized counterpart) that effectively encodes all the information of quasi-symmetries in the original network. The latter is a powerful instrument for obtaining worthwhile insights about node centrality (obtaining the nodes that are unique from that act as imitators with respect to the others) and community detection ( quasi-symmetric groups of nodes).
