description: Background: Cardiac rehabilitation (CR) is an established treatment for coronary artery disease (CAD) that may also improve psychological functioning. However, the extent to which reductions in depressive and anxious symptoms are clinically meaningful remains unclear. This study examined the proportion of patients achieving a minimal clinically important difference (MCID) on the Hospital Anxiety and Depression Scale (HADS) following CR completion and whether these differences are associated with patient characteristics and subsequent mortality. Methods: Retrospective analyses were performed on data from an observational cohort study of CAD patients following coronary catheterization who completed a 12-week CR program during 2009-2019 (TotalCardiologyTM Rehabilitation, Calgary). Patient characteristics and depressive and anxious symptom severity were measured at baseline and post-CR. Mortality data were extracted from Alberta Vital Statistics. A MCID in depressive and anxious symptoms was indicated by an established cut-off (>1.7 decrease in HADS-Anxiety or HADS-Depression scores). Results: Among 6,208 patients (60.5 ± 10.8 years, 20.8% female), 13.0% and 15.9% achieved clinically significant reductions in HADS-Depression and HADS-Anxiety scores, respectively. In patients with baseline HADS-Depression >8 (n = 657), 31.2% reported improved severity of depressive symptoms. In patients with baseline HADS-Anxiety >8 (n = 1,509), 32.0% reported improved severity of anxious symptoms. Higher baseline anxious symptoms, depressive symptoms, and younger age were associated with a greater likelihood of improvements in depressive symptoms (OR = 0.98, 95% CI [0.97–0.99]) and anxiety (OR = 0.99 [0.98, 0.99]). Higher baseline cardiorespiratory fitness (OR = 1.03 [1.00, 1.06]) and higher baseline hemoglobin A1C (OR = 1.00 [1.00, 1.00]) were associated with improvements in anxiety. A reduction in anxiety during CR was associated with lower all-cause mortality at 3-year follow-up (HR = 0.12, [0.02, 0.88]) in patients with elevated baseline anxiety symptoms. Conclusion: CR completion is associated with improved depressive and anxious symptoms in one-third of patients, which could translate to improved health outcomes. A considerable subset of program completers remained symptomatic and may require targeted psychological intervention. Age, cardiorespiratory fitness, blood sugar control, and baseline mood/anxiety symptoms might contribute to differential treatment response.
The Application of Analogue Input and Output to Computer Programs Used as Design Tools
Creators: name: Newton, Anthony

description: It is widely recognised that many designers have difficulty getting decision-support from the technical information that is available in many fields of expertise. A possible remedy is to display the relevant calculated relationships in a human-computer interface comprising an animated graph, ie a graph which is continuously and smoothly updated as the user manipulates analogue controls. The theoretical premise is that this smooth and intimate interaction supports the intuitive mental processes, allowing the user to create internal mental models appropriate to the intuitive thinking employed in the creation of design. Evaluation is thereby made into a tool of synthesis. The key issue was believed to be the removal of closure, (ie the existence of definite input and output phases in the dialogue) and its replacement by a continuous two-way flow of information. A series of animated interfaces was built. Preliminary tests ina context closely related to a particular design activity showed strong user preference for this form of interaction. A context-free implementation was set up and experiments were conducted to characterise the effects of closure on subject behaviour. Clear differences in user behaviour were observed to correspond to the existence of closure or its absence. However none of the metrics adopted reflected this to any great degree of confidence in numerical terms. It is concluded that the interface is clearly attractive to users, who feel better supported by it. The failure to achieve corresponding benefits in terms of the numeric results is ascribed to the degree of abstraction incorporated into the design of the experiment, which impoverished its representation of reality. The need to exercise care in any abstractions made in further work is discussed and the option of field testing is recommended for consideration.

description: The thesis focuses on the transport phenomena of liquid metal (LM) drops in a viscous, non-oxidizing environment, specifically using eutectic alloys of gallium (Ga) like Galinstan (68.5% gallium, 21.5% indium, and 10.0% tin). Ga-based LMs have enabled advancements in bio-devices, flexible circuits, and actuators. However, significant gaps exist in understanding the spatial-temporal behaviour of LM drops, particularly in impingement, splashing, and planar coalescence. A computational approach using C++ OpenFOAM libraries was adopted to address these gaps. Experimental analysis of LMs is challenging due to spontaneous oxidation and opacity, complicating imaging and fluid dynamics study. Extensive testing ensured reliability by comparing findings with existing numerical models. For drop impingement, the study utilized the Weber number (We) and Ohnesorge number (Oh) to examine aspects like temporal spreading factor, maximum spreading factor, and contact time on surfaces. Various droplet behaviours, including deposition, rebound, and splash, were observed, identifying a mechanism for bubble entrapment during the recoiling phase. For drop splashing, the onset of splashing in a viscous medium was explored, examining features like droplet diameter, ejection time, and ejection angle. For drop planar coalescence, the mechanisms for partial coalescence were studied, identifying critical parameters distinguishing partial from complete coalescence at the liquid-liquid interface. The potential occurrence of vortices during partial coalescence, drop reduction ratio, and time of coalescence were investigated. The bubble entrapment phenomenon was characterized and compared with existing entrainment modes, with additional tests assessing the influence of the surrounding medium on coalescence dynamics.

description: Self-induced flavor conversions of supernova (SN) neutrinos can strongly modify the flavor dependent fluxes. We perform a linearized flavor stability analysis with accretion-phase matter profiles of a 15 M_sun spherically symmetric model and corresponding neutrino fluxes. We use realistic energy and angle distributions, the latter deviating strongly from quasi-isotropic emission, thus accounting for both multi-angle and multi-energy effects. For our matter and neutrino density profile we always find stable conditions: flavor conversions are limited to the usual MSW effect. In this case one may distinguish the neutrino mass hierarchy in a SN neutrino signal if the mixing angle theta_13 is as large as suggested by recent experiments.

description: The impact of isolated-photon data from proton-(anti)proton collisions at RHIC, SppbarS, Tevatron and LHC energies, on the parton distribution functions of the proton is studied using a recently developed Bayesian reweighting method. The impact on the gluon density of the 35 existing isolated-gamma measurements is quantified using next-to-leading order (NLO) perturbative QCD calculations complemented with the NNPDF2.1 parton densities. The NLO predictions are found to describe well most of the datasets from 200 GeV up to 7 TeV centre-of-mass energies. The isolated-photon spectra recently measured at the LHC are precise enough to constrain the gluon distribution and lead to a moderate reduction (up to 20%) of its uncertainties around fractional momenta x~0.02. As a particular case, we show that the improved gluon density reduces the PDF uncertainty for the Higgs boson production cross section in the gluon-fusion channel by more than 20% at the LHC. We conclude that present and future isolated-photon measurements constitute an interesting addition to coming global PDF analyses.

description: Oxygen tension plays an integral role in gastrointestinal homeostasis. When oxygen concentrations become suboptimal (hypoxia), mammalian cells rely on the hypoxia-inducible factor (HIF) to combat cellular stress and augment glycolytic flux. In the gastrointestinal epithelium, this cellular response is paramount as the luminal facing epithelial cells exist in a state of physiologic hypoxia that can be further altered by pathogens. Although growing evidence suggests tissue and blood protozoan parasites can activate HIF in a mammalian host, much remains to be understood in the context of enteric protozoan infections. This study uncovered the role of HIF-1α and associated epithelial hypoxic signature upon Giardia duodenalis infection, a leading cause of diarrheal disease worldwide. Coculture experiments were carried out using Caco-2 colonic epithelial cells infected with a human isolate of G. duodenalis (GSM) in normoxic (21% O2) or hypoxic (1% O2) conditions. Under normoxic conditions, infected cells displayed a time-dependent increase in HIF-1α protein expression, the oxygen-dependent subunit of HIF. This observation was concomitant with increased expression of HIF-target genes, including those responsible for combatting cellular stress (i.e., VEGFA, GADD45A, ANKRD37), and augmenting glycolytic flux (i.e., HK2, LDHA). Intracellular metabolomic analysis of normoxic infected cells revealed simultaneous increases in glucose-6-phosphate and lactate, the metabolic outputs of HK2 and LDHA, respectively. Under hypoxic conditions, HIF-1α stabilization was not significantly different compared to uninfected hypoxic control cells. However, HIF-target genes were still upregulated, albeit to a lesser degree compared to normoxic infected cells. Importantly, the metabolome of infected epithelial cells differed greatly between normoxic and hypoxic conditions, highlighting the influential role of oxygen during G. duodenalis infection. After 24 hours, HIF-1α stabilization and alterations to HIF-target gene expression were no longer detected. These findings indicate G. duodenalis induces a hypoxic response driven by HIF-1α stabilization in normoxic intestinal epithelial cells, while simply exacerbating this cellular response in hypoxic conditions. The stabilization of HIF-1α in the absence of oxygenic stress highlights a novel metabolic cell rescue mechanism in response to enteropathogens.

description: More individuals than ever before are enrolling in post-secondary education to further their education and become a competitive candidate in the labor market. Unfortunately, many post-secondary students experience a variety of stressors and demands in a variety of life domains (e.g., academic, financial, and social). This type of chronic, unmanaged stress can lead to academic burnout. Academic burnout is associated with a multitude of negative effects for post-secondary students, including reduced academic performance and mental well-being. Both time management and self-compassion are suggested buffers against academic stress and are positively linked to increased academic success. However, their potential protective role against academic burnout remains relatively unexplored. A cross-sectional study of 78 students was conducted to examine time management and self-compassion as predictors of academic burnout. A regression analysis found that high ratings of self-compassion, but not time management, predicted lower levels of academic burnout. Gender differences were present within self-compassion, but gender was not found to moderate self-compassion’s relationship with academic burnout. The results suggest that being kind and understanding rather than being harshly self-critical when faced with challenges or disappointments helps to buffer the burnout experienced by students in higher education. Students could be better prepared to deal with the stress of post-secondary education by learning adaptive strategies to manage their stress through increased compassion towards oneself.

description: Abstract Rules of origin play a pivotal role in free trade agreements. Apart from serving as a tool to distinguish goods by determining the nationality of a product, rules of origin have the capacity to increase trade relations or deter it. Of course, it is the hope of any viable state to increase profitable trading relations, and if rules of origin can help with that, it becomes expedient to fully understand how these rules of origin operate. In Africa, we see rules of origin being implemented amongst the Regional Economic Communities (RECs), but this has come with many struggles. In fact, low intra-African trade can be narrowed down to complex rules of origin regimes deployed in regional agreements in Africa. As of date, the major RECs have each implemented different rules of origin, leading to the co-existence of conflicting rules of origin across Africa. This non-uniformity in the rules of origin regimes in Africa has resulted in low continental trade in Africa. As such, these RECs have not yielded the expected increase in intra-African trade. With the creation of the African Continental Free Trade Area (AfCFTA), which currently doubles as the latest and largest FTA in Africa, it is expected that better rules of origin will be deployed to mitigate the existing intra-African trade deficits. This thesis thus deploys a doctrinal approach in determining whether AfCFTA’s rules of origin are positioned to achieve greater intra-African trade. Consequently, this thesis uncovers some lapses in AfCFTA’s rules of origin and calls for harmonization of all the rules of origin in Africa and recommends a possible amendment to Article 19 of the Agreement establishing AfCFTA to accommodate the intended harmonization.
Rapid growth of gas-giant cores by pebble accretion

description: The observed lifetimes of gaseous protoplanetary discs place strong constraints on gas and ice giant formation in the core accretion scenario. The approximately 10-Earth-mass solid core responsible for the attraction of the gaseous envelope has to form before gas dissipation in the protoplanetary disc is completed within 1-10 million years. Building up the core by collisions between km-sized planetesimals fails to meet this time-scale constraint, especially at wide stellar separations. Nonetheless, gas-giant planets are detected by direct imaging at wide orbital distances. In this paper, we numerically study the growth of cores by the accretion of cm-sized pebbles loosely coupled to the gas. We measure the accretion rate onto seed masses ranging from a large planetesimal to a fully grown 10-Earth-mass core and test different particle sizes. The numerical results are in good agreement with our analytic expressions, indicating the existence of two accretion regimes, one set by the azimuthal and radial particle drift for the lower seed masses and the other, for higher masses, by the velocity at the edge of the Hill sphere. In the former, the optimally accreted particle size increases with core mass, while in the latter the optimal size is centimeters, independent of core mass. We discuss the implications for rapid core growth of gas-giant and ice-giant cores. We conclude that pebble accretion can resolve the long-standing core accretion time-scale conflict. This requires a near-unity dust-to-gas ratio in the midplane, particle growth to mm and cm and the formation of massive planetesimals or low radial pressure support. The core growth time-scale is shortened by a factor 30-1,000 at 5 AU and by a factor 100-10,000 at 50 AU, compared to the gravitationally focused accretion of, respectively, low-scale-height planetesimal fragments or standard km-sized planetesimals.

description: We introduce an order parameter for symmetry-protected phases in one dimension which allows to directly identify those phases. The order parameter consists of string-like operators and swaps, but differs from conventional string order operators in that it only depends on the symmetry but not on the state. We verify our framework through numerical simulations for the SO(3) invariant spin-1 bilinear-biquadratic model which exhibits a dimerized and a Haldane phase, and find that the order parameter not only works very well for the dimerized and the Haldane phase, but it also returns a distinct signature for gapless phases. Finally, we discuss possible ways to measure the order parameter in experiments with cold atoms.

description: In this work we investigate the quantum theory of light propagating in $D-$dimensional de Sitter spacetimes. To do so, we use the method of dynamic invariants to obtain the solution of the time-dependent Schrödinger equation. The quantum behavior of the electromagnetic field in this background is analyzed. As the electromagnetism loses its conformality in $D\neq4$, we point that there will be particle production and comoving objects will feel a Bunch-Davies thermal bath. This may become important in extra dimension physics and raises the intriguing possibility that precise measurements of the Cosmic Microwave Background could verify the existence of extra dimensions.

description: Aqueous batteries are safe and environmentally friendly energy storage devices, suitable for intermittent renewable energy sources and carbon removal applications. However, these batteries are hindered by the low operating potential which leads to limitation in energy density. In this thesis, aqueous battery chemistry concept is applied for two different applications such as: a redox-flow battery transformation to an all-gel battery and a seawater-battery for carbon removal application. Flexible, scalable, and low-cost energy storage solutions are required for the widespread use of renewable energy and the mitigation of climate change. In this regard, redox flow batteries are scalable due to their ability to decouple power and energy; however, the commercial applications of these batteries are limited by expensive ion-selective membranes. An auxiliary electrode (AE) mediated membrane-free redox battery concept was demonstrated and different AE materials were screened for their application in vanadium based redox battery. In an AE mediated membrane-free vanadium redox battery, the Coulombic efficiency of the system was limited to 36%. The low Coulombic efficiency observed in AE based battery was mitigated by using a gel-battery design approach in which Bi/BiOCl and V4+/V5+ redox couples were utilized in a gel-based architecture. The Bi/BiOCl conversion reaction based redox couple was demonstrated to work reversibly against traditional vanadium-based redox pair in an aqueous electrolyte. Redox active materials in this cell design are in the gel form, and a traditional membrane or a separator is not required. This proof-of-concept all-gel battery delivered 0.9 V with a volumetric energy density of 22.14 Wh L-1. For carbon removal applications, an aqueous battery with seawater electrolyte was studied. In this battery, iron phosphate (FePO4) electrode was utilized to manipulate ions in different seawater aliquots to generate sodium hydroxide, a base to use in ocean alkalinity enhancement. Electrochemical analysis, Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD) and X-ray Photoelectron Spectroscopy (XPS) revealed that Na+ ions can be reversibly intercalated in FePO4. The alkalinity titration was used to determine the increase in alkalinity of seawater. The results indicated that a 16% increase in alkalinity was achieved in 15 ml of synthetic seawater over a period of 3.5 hours (one cycle) using the FePO4 electrode coupled with Pt electrode. A seawater electrolyte based battery with Ni(OH)2/NiOOH redox reaction in place of Pt electrode coupled with FePO4 electrode was studied. The battery delivered a potential of 0.6 V and the galvanostatic cycling experiments revealed that the battery can operate in seawater electrolyte for 50 cycles with 94% Coulombic efficiency.

description: Hypothesis
We hypothesized that P wave terminal Force in the V1 lead (PTFV1) would be associated with leukoaraiosis and subclinical infarcts, especially cortical infarcts, in a population-based, multi-ethnic cohort.

Methods
PTFV1 was collected manually from baseline electrocardiograms of clinically stroke-free Northern Manhattan Study participants. Investigators read brain MRIs for superficial infarcts, deep infarcts, and white matter hyperintensity volume (WMHV). WMHV was adjusted for head size and log transformed, achieving a normal distribution. Logistic regression models investigated the association of PTFV1 with cortical and with all subclinical infarcts. Linear regression models examined logWMHV. Models were adjusted for demographics and risk factors.

Results
Among 1174 participants with PTFV1 measurements, the mean age at MRI was 70 ± 9 years. Participants were 14.4% white, 17.6% black, and 65.8% Hispanic. Mean PTFV1 was 3587.35 ± 2315.62 μV-ms. Of the 170 subclinical infarcts, 40 were cortical. PTFV1 ≥ 5000 μV-ms was associated with WMHV in a fully adjusted model (mean difference in logWMHV 0.15, 95% confidence interval 0.01–0.28). PTFV1 exhibited a trend toward an association with cortical infarcts (unadjusted OR per SD change logPTFV1 1.30, 95% CI 0.94–1.81), but not with all subclinical infarcts.

Conclusion
Electrocardiographic evidence of left atrial abnormality was associated with leukoaraiosis.

description: The impetus for my doctoral research came from my desire to explore the possible applications of drama-based pedagogies within the English Language Arts (ELA) curriculum. To do this, I examined how drama-based work, inspired by posthumanist concepts, could be applied to create additional opportunities for embodiment and relationality within secondary ELA classrooms. Within this study, literacy was a central focus and was defined as practices related to multiple forms of meaning making that included embodiment and relationality. Case study methodology informed by posthumanist concepts drove the data collection and analysis. Data was collected in a Grade 12 ELA classroom through observations, conversations, classroom artifacts, and student performances, and analyzed through both coding and iterative cycles of writing. The data was then used to explore the roles of affect, embodiment, and relationality in secondary ELA classrooms and to see how drama-based work could encourage more multimodal explorations of text. This study found that drama-based work encouraged pedagogical reflection and inspired ways through which to approach literacy teaching. My research contributes a picture of how drama-based work in one secondary ELA classroom enhanced meaning making around texts by drawing on drama’s embodied and relational learning opportunities. It demonstrates how drama can be used to introduce new avenues to help students find “what is real by making believe” (Campbell, 2021).

description: The primordial curvature perturbation ζmay be generated by some curvaton field σ, which is negligible during inflation and has more or less negligible interactions until it decays. In the current scenario, the curvaton starts to oscillate while its energy density ρ_σis negligible. We explore the opposite scenario, in which ρ_σdrives a few e-folds of inflation before the oscillation begins. In this scenario for generating ζit is exceptionally easy to solve the ηproblem; one just has to make the curvaton a string axion, with anomaly-mediated susy breaking which may soon be tested at the LHC. The observed spectral index n can be obtained with a potential V\propto ϕ^p for the first inflation; p=1 or 2 is allowed by the current uncertainty in n but the improvement in accuracy promised by Planck may rule out p=1. The predictions include (i) running n'\simeq 0.0026 (0.0013) for p=1 (2) that will probably be observed, (ii) non-gaussianity parameter f_NL \sim -1 that may be observed, (iii) tensor fraction r is probably too small to ever observed.

description: Apolipoprotein E (APOE) genotype is believed to play a role in the onset of dementia, though less is known about its relationship with non-pathogenic age-related cognitive decline. We assessed whether APOE was a risk factor for cognitive decline among older Taiwanese adults using nationally representative data. General cognition was measured longitudinally over eleven years; domain-specific cognitive assessments of working memory, declarative learning and three aspects of attention (executive function, alerting, and orientation) were performed once. Having at least one risky APOE allele was associated with more rapid longitudinal cognitive decline compared to those with no risky alleles. Some evidence from the cross-sectional analysis of domain-specific cognitive assessments suggested that APOE genotype may be more closely associated with working memory and declarative learning than with attention. Most genetic studies of cognition include only populations of European descent; extension is crucial. This study confirmed the association between APOE genotype and the rate of cognitive decline in a predominantly Han Chinese population. Additional studies on diverse populations are warranted.

description: The construction of the Nike Vaporfly 4% shoe has led to the widespread adoption of Advanced Footwear Technology (AFT) in running footwear design. Characterized by elements such as a compliant and resilient midsole material, a stiffening component within the midsole, and pronounced forefoot curvature, the technology is believed to enhance running performance. However, the contributions of the specific AFT features and the underlying biomechanical mechanisms remain unclear. Therefore, this thesis aimed to investigate the effects of selected AFT features, specifically the curved carbon fiber plate and PEBA midsole foam, on running performance and mechanics. In four individual studies, male recreational runners performed physiological and biomechanical running trials in an original version of the Nike Vaporfly 4% shoe, and two prototype (No Plate and EVA) versions of the same. The first study revealed that the curved carbon fiber plate and PEBA midsole foam significantly reduced the energy cost of running by 1.9% and 2.2%, respectively. However, these energetic improvements were not linked to changes in activation of two plantar flexor muscles. Subsequent studies investigated the teeter-totter effect and lower limb joint work as potential underlying mechanisms driving the energy cost improvements. The findings confirmed that the curved carbon fiber plate enhances propulsion and reduces energy cost. An investigation into lower limb joint work demonstrated that the curved plate decreases energy loss at the metatarsophalangeal (MTP) joint and redistributes positive work from the ankle to the MTP, contributing to more efficient running mechanics. The effects of midsole material varied among subjects, which may explain the large variations in performance improvements observed previously with the use of AFTs despite their overall effectiveness. This thesis enhances our understanding of how specific features of AFT optimize running performance and informs future innovations aimed at further improving running energetics.

description: We present a new concept for the generation of optical lattice waves. For all four families of nondiffracting beams, we are able to realize corresponding nondiffracting intensity patterns in one single setup. The potential of our approach is shown by demonstrating the optical induction of complex photonic discrete, Bessel, Mathieu, and Weber lattices in a nonlinear photorefractive medium. However, our technique itself is very general and can be transferred to optical lattices in other fields like atom optics or cold gases in order to add such complex optical potentials as a new concept to these areas as well.

title: The Mediating and Moderating Role of Emotion Regulation and Demographic Factors in the Relationship Between Mindfulness and Psychosocial Symptoms in People with Cancer

description: Background: Many people living with cancer (PWC) experience distressing psychosocial symptoms that are chronic and long-lasting even after treatment completion such as depression, anxiety, fear of cancer recurrence (FCR), and fatigue. Mindfulness-Based Interventions (MBIs) are evidenced to reduce psychosocial symptoms experienced by cancer survivors by decreasing reliance on maladaptive emotion regulation strategies such as rumination and experiential avoidance (EA). However, mediation studies testing rumination and EA are few and have yet to model all aforementioned psychosocial outcomes. Although there is evidence that sex and age predict higher levels of psychosocial symptoms, lower mindfulness, and higher rumination and EA, studies have yet to assess these demographic factors as moderators of the relationship between mindfulness and psychosocial symptoms through the specified mediators. This study therefore aimed to (i) explore the mediating role of rumination and EA in the relationship between mindfulness and a range of psychosocial symptoms and (2) test sex and age as moderators of the mediation models. Methods: This cross-sectional study assessed baseline data from 134 participants recruited for a mindfulness app trial. Patient reported measures for trait mindfulness, rumination, experiential avoidance, depression, anxiety, fear of cancer recurrence, and fatigue were collected. Structural Equation Modelling (SEM) was employed in R to test mediation and moderated mediation models. Results: The sample was 49.3% female with a mean age of 61.78. Types of cancer diagnoses included varying stages of: breast – 35.1%, prostate – 23.1%, lymphoma – 9.7%, gastrointestinal – 14.2%. Time since treatment ranged from 17-6348 days. Ethnicities included: White - 79.9%, Black - 1.5%, South Asian – 4.5%, Mixed or other – 8.7%. Annual incomes ranged from $5,000 to over $100,000. Rumination was a significant partial mediator between mindfulness and depression and anxiety as well as FCR, but not fatigue. EA may act as a weak mediator from mindfulness to FCR only. Subgroup analyses based on sex revealed that rumination may be particularly important for females in accounting for the relationship between mindfulness and depression and anxiety. Conclusion: Results indicate that rumination may be a stronger mediator than EA for anxiety, depression and FCR, and that this may be particularly important for females when compared to males. Findings will inform MBIs to target relevant mediators to reduce distressing psychosocial symptoms and improve quality of life in PWC.

description: The Brain Drain phenomenon is particularly heterogeneous and is characterized by peculiar specifications. It influences the economic fundamentals of both the country of origin and the host one in terms of human capital accumulation. Here, the brain drain is considered from a microeconomic perspective: more precisely we focus on the individual rational decision to return, referring it to the social capital owned by the worker. The presented model compares utility levels to justify agent migration conduct and to simulate several scenarios within a computational environment. In particular, we developed a simulation framework based on two fundamental individual features, i.e. risk aversion and initial expectation, which characterize the dynamics of different agents according to the evolution of their social contacts. Our main result is that, according to the value of risk aversion and initial expectation, the probability of return migration depends on their ratio, with a certain degree of approximation: when risk aversion is much bigger than the initial expectation, the probability of returns is maximal, while, in the opposite case, the probability for the agents to remain abroad is very high. In between, when the two values are comparable, it does exist a broad intertwined region where it is very difficult to draw any analytical forecast.

description: A common feature of biological networks is the geometric property of self-similarity. Molecular regulatory networks through to circulatory systems, nervous systems, social systems and ecological trophic networks, show self-similar connectivity at multiple scales. We analyze the relationship between topology and signaling in contrasting classes of such topologies. We find that networks differ in their ability to contain or propagate signals between arbitrary nodes in a network depending on whether they possess branching or loop-like features. Networks also differ in how they respond to noise, such that one allows for greater integration at high noise, and this performance is reversed at low noise. Surprisingly, small-world topologies, with diameters logarithmic in system size, have slower dynamical timescales, and may be less integrated (more modular) than networks with longer path lengths. All of these phenomena are essentially mesoscopic, vanishing in the infinite limit but producing strong effects at sizes and timescales relevant to biology.

Heavy pseudoscalar-meson decay constants with strangeness from the extended nonlocal chiral-quark model

description: We study the weak-decay constants for the heavy pseudoscalar mesons, D, Ds, B, and Bs. For this purpose, we employ the extended nonlocal chiral-quark model (ExNLChQM), motivated by the heavy-quark effective field theory as well as the instanton-vacuum configuration. In addition to the heavy-quark symmetry and the nonlocal interactions between quarks and pseudoscalar mesons in ExNLChQM, a correction for the strange-quark content inside Ds and Bs is also taken into account and found to be crucial to reproduce the empirical values. From those numerical results, we obtain f_{D,Ds,B,Bs}=(207.53, 262.56, 208.13, 262.39) MeV, which are in good agreement with experimental data and other theoretical estimations. Using those numerical results, we compute the CKM matrix elements and the Cabibbo angle, using various mesonic and leptonic heavy-meson decay channels, resulting in (|V_{cd}|,|V_{cs}|,|V_{ub}|,|V_{td}|/|V_{ts}|)=(0.224,0.968,<5.395*10^{-3},0.215) and theta_C=12.36^o which are well compatible with available data.
