description: We present a recent analysis with 1996 SOHO CELIAS CTOF data, which reveals correlations of He+ pickup ion fluxes and spectra with the magnetic field strength and solar wind density. The motivation is to better understand the ubiquitous large variations in both pickup ion fluxes and their velocity distributions found in interstellar pickup ion datasets. We concentrate on time periods of that can be associated with compression regions in the solar wind. Along with enhancements of the overall pickup ion fluxes, adiabatic heating and acceleration of the pickup ions are also observed in these regions. Transport processes that lead to the observed compressions and related heating or acceleration are discussed. A shift in velocity space associated with traveling interplanetary compression regions is observed, and a simple model presented to explain this phenomenon based on the conserved magnetic adiabatic moment.

description: We present a new implementation of the GAlaxy Evolution and Assembly (GAEA) semi-analytic model, that features an improved modelling of the process of cold gas accretion onto supermassive black hole (SMBHs), derived from both analytic arguments and high-resolution simulations. We consider different scenarios for the loss of angular momentum required for the available cold gas to be accreted onto the central SMBHs, and we compare different combinations of triggering mechanisms, including galaxy mergers and disc instabilities in star forming discs. We compare our predictions with the luminosity function (LF) observed for Active Galactic Nuclei (AGN) and we confirm that a non-instantaneous accretion timescale (either in the form of a low-angular momentum reservoir or as an assumed light curve evolution) is needed in order to reproduce the measured evolution of the AGN-LF and the so-called AGN-downsizing trend. Moreover, we also study the impact of AGN feedback, in the form of AGN-driven outflows, on the SF properties of model galaxies, using prescriptions derived both from empirical studies or from numerical experiments. We show that AGN-driven outflows are effective in suppressing the residual star formation rate in massive galaxies ($> 10^{11} M_\odot$) without changing their overall assembly history. These winds also affect the SFR of lower mass galaxies, resulting in a too large fraction of passive galaxies at $< 10^{10} M_\odot$. Finally, we study the Eddington ratio distribution as a function of SMBH mass, showing that only objects more massive than $10^8 M_\odot$ are already in a self-regulated state as inferred from observations.

description: We consider the passage of long polymers of length N through a hole in a membrane. If the process is slow, it is in principle possible to focus on the dynamics of the number of monomers s on one side of the membrane, assuming that the two segments are in equilibrium. The dynamics of s(t) in such a limit would be diffusive, with a mean translocation time scaling as N^2 in the absence of a force, and proportional to N when a force is applied. We demonstrate that the assumption of equilibrium must break down for sufficiently long polymers (more easily when forced), and provide lower bounds for the translocation time by comparison to unimpeded motion of the polymer. These lower bounds exceed the time scales calculated on the basis of equilibrium, and point to anomalous (sub-diffusive) character of translocation dynamics. This is explicitly verified by numerical simulations of the unforced translocation of a self-avoiding polymer. Forced translocation times are shown to strongly depend on the method by which the force is applied. In particular, pulling the polymer by the end leads to much longer times than when a chemical potential difference is applied across the membrane. The bounds in these cases grow as N^2 and N^{1+ν}, respectively, where νis the exponent that relates the scaling of the radius of gyration to N. Our simulations demonstrate that the actual translocation times scale in the same manner as the bounds, although influenced by strong finite size effects which persist even for the longest polymers that we considered (N=512).

description: This paper analyzes the dynamic and size effects of the U.S. monetary policy shock, a proxy for advanced economies' monetary policy shock, as well as domestic monetary and exchange rate shocks on gross foreign direct and portfolio investment in flows to emerging markets. It uses panel and country-specific structural vector auto-regressions to analyze and compare the dynamic, size, and differential impacts of the shocks on each in ow category. Foreign direct investment in ow's response to policy shocks is weak but persistent while that of foreign portfolio investment is strong and on impact. The implication is that macro-prudential and capital control policies may be more effective when they are directed at portfolio in flows. In addition to providing a richer dynamic structure, the use of structural vector auto-regressions provides a clearer comparison of "push" and "pull" factors on financial flows via forecast error variance decomposition. Although the U.S. monetary policy explains a significant variation in both gross in flows, this paper does not find a consistent evidence of "push" over "pull" factors in either capital in ow type or across the countries.

The qualitative part of the study, namely interviews with students in the course, showed that the native language of the students appeared not to be a factor in understanding mathematical language, that there was little relation between problems as stated on the exam and what the students had been taught, and that the students' grasp of the underlying concepts was poor. If students are expected to learn the concepts taught in Finite Mathematics, more emphasis should be placed on teaching mathematics language and vocabulary, with attention to the basic concepts. Problems must be clearly stated in a way that the students can understand. Students need practice translating concepts into formulas and conversely; instructors need to make the concepts and problems relevant to the students.

description: The effects of households'indebtedness on their house-selling decisions are studied in a dynamic equilibrium model with search in the housing market and defaultable long-term mortgages. In equilibrium, both sellers' asking prices and time-to-sell increase with the relative size of their outstanding mortgages. In turn, the liquidity of the housing market associated with time-to-sell determines the mortgage standards of competitive lenders, measured by the maximum loan-to-value (LTV) ratio offered at origination. Calibrated to the U.S. economy, the model generates, as observed, positive correlations over time between house prices and LTV's at origination and across sellers among asking prices, time-to-sell, and LTV's outstanding.

description: An industrial process includes many devices, variables, and sub-processes that are physically or electronically interconnected. These interconnections imply some level of correlation between different process variables. Since most of the alarms in a process plant are defined on process variables, alarms are also correlated. However, this can be a nuisance to operators, for one fault might trigger a, sometimes large, number of alarms. So, it is essential to find and correct correlated alarms. In this paper, we study different methods and techniques proposed to measure correlation or similarity between alarms. The similarity indices are first analytically calculated and then studied and compared. The results are also validated using Monte-Carlo simulation.

description: We show that soft spheres interacting with a linear ramp potential when overcompressed beyond the jamming point fall in an amorphous solid phase which is critical, mechanically marginally stable and share many features with the jamming point itself. In the whole phase, the relevant local minima of the potential energy landscape display an isostatic contact network of perfectly touching spheres whose statistics is controlled by an infinite lengthscale. Excitations around such energy minima are non-linear, system spanning, and characterized by a set of non-trivial critical exponents. We perform numerical simulations to measure their values and show that, while they coincide, within numerical precision, with the critical exponents appearing at jamming, the nature of the corresponding excitations is richer. Therefore, linear soft spheres appear as a novel class of finite dimensional systems that self-organize into new, critical, marginally stable, states.

description: The advent of COVID-19 has disrupted all facets of human lives. As of September 2020, there is no effective viral therapy for the disease, thus necessitating research efforts toward providing solutions to the diverse areas where the pandemic has wreaked havoc. As a way of reducing the spread of the disease, the South African government declared COVID-19 a national disaster and implemented nationwide lockdowns with several regulations. Nevertheless, the success of such synergized efforts primarily depends on the people’s attitudes and perceptions toward the multifaceted management of the pandemic. Therefore, this current study aims to discover what topical issues relating to the pandemic are being discussed by the populace and what impacts these issues have on compliance with regulations, including how they can aid in the implementation of the measures put in place by the government, as we analyze discussions relating to COVID-19 using data harvested from Twitter – social media and opinion mining platform. The Latent Dirichlet Allocation (LDA) algorithm was applied for the extraction of noteworthy topics. From the experiments conducted, it was observed that alcohol sale and consumption, staying home, daily statistics tracing, police brutality, 5G and vaccines conspiracy theories were among the topics discussed and around which attitudes and perceptions were formed by the citizens. The findings also revealed people’s resistance to measures that affect their economic activities, and their unwillingness to take tests or vaccines as a result of fake news and conspiracy theories. These findings can assist the government and policymakers in redirecting their efforts by addressing the citizens’ concerns and reactions to the instituted measures toward an anticipated overall success.

description: We propose a new model for the disk-jet connection in black hole x-ray transients and active galactic nuclei. In our model, the inner part of the accretion disk around the central black hole switches between two states. In one state, the accretion energy is dissipated locally (some within the disk, some within a corona) to produce the observed disk luminosity. In the second state, the accretion energy is deposited into the bulk flow of a relativistic jet. We associate the transition between the two states with the generation of a global, poloidal magnetic field. We show that this model can explain the observed behavior of black hole accretors.

description: This paper studies a repeated-game model in which firms can build a repu- tation for rewarding innovative employees. In any Pareto effcient equilibrium, low-value innovations get developed in established firms, while high-value inno- vations get developed in startups. The threshold level can be discontinuous, so otherwise similar firms may exhibit very different levels of innovation. The paper also shows that the optimal incentive contract for innovative employees has an option-like form, and that a firm may want to worsen the distribution of possible innovations. The model's predictions are consistent with a broad set of observed regularities regarding the creation of employee startups.

description: Using velocity profile measurements based on dynamic light scattering and coupled to structural and rheological measurements in a Couette cell, we present evidences for a shear-banding scenario in the shear flow of the onion texture of a lyotropic lamellar phase. Time-averaged measurements clearly show the presence of structural shear-banding in the vicinity of a shear-induced transition, associated to the nucleation and growth of a highly sheared band in the flow. Our experiments also reveal the presence of slip at the walls of the Couette cell. Using a simple mechanical approach, we demonstrate that our data confirms the classical assumption of the shear-banding picture, in which the interface between bands lies at a given stress $σ^\star$. We also outline the presence of large temporal fluctuations of the flow field, which are the subject of the second part of this paper [Salmon {\it et al.}, submitted to Phys. Rev. E].
Cosmic structures from a mathematical perspective 1. Dark matter halo mass density profiles

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: The shapes of individual self-gravitating structures of an ensemble of identical, collisionless particles have remained elusive for decades. In particular, a reason why mass density profiles like the Navarro-Frenk-White or the Einasto profile are good fits to simulation- and observation-based dark matter halos has not been found. Given the class of three dimensional, spherically symmetric power-law probability density distributions to locate individual particles in the ensemble mentioned above, we derive the constraining equation for the power-law index for the most and least likely joint ensemble configurations. We find that any dark matter halo can be partitioned into three regions: a core, an intermediate part, and an outskirts part up to boundary radius $r_\mathrm{max}$. The power-law index of the core is determined by the mean radius of the particle distribution within the core. The intermediate region becomes isothermal in the limit of infinitely many particles. The slope of the mass density profile far from the centre is determined by the choice of $r_\mathrm{max}$ with respect to the outmost halo particle, such that two typical limiting cases arise that explain the $r^{-3}$-slope for galaxy-cluster outskirts and the $r^{-4}$-slope for galactic outskirts. Hence, we succeed in deriving the mass density profiles of common fitting functions from a general viewpoint. These results also allow to find a simple explanation for the cusp-core-problem and to separate the halo description from its dynamics.

description: We describe a study of high-energy Compton beam polarimeters for the future e+e- linear collider machine TESLA. A segment of the beam delivery system has been identified, which is aligned with the e+e- collision axis and which has a suitable configuration for high-quality beam polarization measurements. The laser envisaged for the polarimeter is similar to an existing facility at DESY. It delivers very short pulses in the 10 ps, 10-100uJ regime and operates with a pattern that matches the pulse and bunch structure of TESLA. This will permit very fast and accurate measurements and an expeditious tune-up of the spin manipulators at the low-energy end of the linac. Electron detection in the multi-event regime will be the principle operating mode of the polarimeter. Other possible operating modes include photon detection and single-event detection for calibration purposes. We expect an overall precision of dP/P=0.5% for the measurement of the beam polarization.

The analysis of gender effects on saving: Evidence from urban poor home -based workers in Thailand
Creators: name: Nguanbanchong, Aphitchaya
Publisher: name: American University
Year: 2023

description: This research investigates how low-income people, particularly informal workers in the urban areas of Bangkok, manage their monetary resources. It describes how they handle their savings and discusses the role of informal savings mechanisms available to them. The second aim is to examine why the propensities to save are different between women and men and how a change in women's bargaining power, measured by decisions over financial allocations and household consumptions, influences household savings. By using the data from the Urban Poor Home-based Worker Survey 2002 (UPHWS 2002) in Bangkok, this study provides some interesting insights on the gender effects on the level of informal savings. A number of conclusions have emerged as follows: (1) the level of informal savings is influenced by a number of factors including income, individual and household characteristics, household bargaining power, social and gender norms; (2) women and men have different propensities to save and women tend to save more than men; (3) men's and women's probability to participate in all savings institutions is different; (4) increases in women's bargaining power have a positive impact on level of household savings. Based on the individual savings models, women's and men's propensity to save may differ due to differences in their perceived interests and perceived risks, which in turn, are affected by gender norms, such as family obligations on Thai women. We first find that Thai women tend to hold higher savings. They save more than Thai men as their incomes increase because they save for children's allowances, education and other expenses, as well as for business purposes. This evidence is also confirmed by the fact that Thai women traditionally are the money-keepers who manage household savings and expenditures. Our results demonstrate the existence of this gender effects on saving patterns of both women and men. In the household bargaining analysis, various indicators of bargaining power are used to examine its impact on the level of household saving. These are: (a) women's control over financial decision (FDMI), (b) women's control over consumption decision (CDMI), and (c) economic obligation index (EOI). The most interesting finding is that an increase in FDMI (or an improvement in women's fallback position) is statistically important in raising household savings. The performance of the CDMI and EOI is less robust than the FDMI. This, however, may be viewed as an interesting field that future research could pursue, possibly by creating extended versions of the measurements of power. From a policy perspective, understanding how low-income family members or households bargain over economic resources can provide us with a better assessment of the effects of economic, social and development strategies on their saving behaviors.

We assume one pair of up and down sector Higgs fields. We show realistic examples including hierarchical and democratic forms of Yukawa matrices.

description: This research investigates how low-income people, particularly informal workers in the urban areas of Bangkok, manage their monetary resources. It describes how they handle their savings and discusses the role of informal savings mechanisms available to them. The second aim is to examine why the propensities to save are different between women and men and how a change in women's bargaining power, measured by decisions over financial allocations and household consumptions, influences household savings. By using the data from the Urban Poor Home-based Worker Survey 2002 (UPHWS 2002) in Bangkok, this study provides some interesting insights on the gender effects on the level of informal savings. A number of conclusions have emerged as follows: (1) the level of informal savings is influenced by a number of factors including income, individual and household characteristics, household bargaining power, social and gender norms; (2) women and men have different propensities to save and women tend to save more than men; (3) men's and women's probability to participate in all savings institutions is different; (4) increases in women's bargaining power have a positive impact on level of household savings. Based on the individual savings models, women's and men's propensity to save may differ due to differences in their perceived interests and perceived risks, which in turn, are affected by gender norms, such as family obligations on Thai women. We first find that Thai women tend to hold higher savings. They save more than Thai men as their incomes increase because they save for children's allowances, education and other expenses, as well as for business purposes. This evidence is also confirmed by the fact that Thai women traditionally are the money-keepers who manage household savings and expenditures. Our results demonstrate the existence of this gender effects on saving patterns of both women and men. In the household bargaining analysis, various indicators of bargaining power are used to examine its impact on the level of household saving. These are: (a) women's control over financial decision (FDMI), (b) women's control over consumption decision (CDMI), and (c) economic obligation index (EOI). The most interesting finding is that an increase in FDMI (or an improvement in women's fallback position) is statistically important in raising household savings. The performance of the CDMI and EOI is less robust than the FDMI. This, however, may be viewed as an interesting field that future research could pursue, possibly by creating extended versions of the measurements of power. From a policy perspective, understanding how low-income family members or households bargain over economic resources can provide us with a better assessment of the effects of economic, social and development strategies on their saving behaviors.

description: The past decade has witnessed the development of a large theoretical literature on the intertemporal approach to the current account. These models typically emphasized the effects on the current account balance of real factors such as productivity, terms of trade, government spending and taxes via intertemporal substitution in consumption, production and investment. Could this micro based theory in any meaningful sense be wrong? The answer lies in the efforts to derive its empirical implications. Essentially the test of this theory is in proving the empirical importance of the role played by the intertemporal substitution. While this paper does not engage in formal statistical testing of the theory, the numbers it presents and the analysis of them shed light on the validity of the key testable hypotheses. The paper models investment and consumption (saving) in ways that emphasize intertemporal optimization and the differing effects of various shocks. Four different kinds of shocks are distinctly treated: transitory or persistent in duration, and common or idiosyncratic across countries. Incorporating these considerations the paper brings out a body of evidence in support of the key propositions of the dynamic-optimizing approach.
Attachment style and childhood sexual abuse: A longitudinal examination
Creators: name: Sypeck, Mia Foley
Publisher: name: American University

description: Attachment theory was utilized as a conceptual framework through which to better understand the antecedents and consequences of childhood sexual abuse. Attachment styles of 49 sexually abused and 54 comparison females (mean age = 12.01; SD = 2.88) were classified as part of a longitudinal, prospective study of the long-term effects of childhood sexual abuse. Abused participants were more likely to be insecurely attached than comparison participants, and certain attachment styles were associated with distinct patterns of abuse when considering factors such as the child's relationship with the perpetrator, the severity and duration of the abuse, and the degree of violence accompanying the abuse. Attachment style was related to concurrent levels of depression, anxiety, dissociation, confidence, and externalizing difficulties, as well as locus of control and perception of family functioning. Ten years subsequent to disclosure, attachment style was related to levels of anxiety, internalizing difficulties, obsessive-compulsive behavior, social phobia, delinquent behavior, and various forms of eating pathology. Both concurrently and in terms of later psychological functioning, a secure attachment style provided the basis for superior adjustment, whereas an insecure attachment style placed participants at risk for greater difficulties. The degree and type of difficulty experienced varied according to the participants' specific insecure attachment strategies. Attachment style also mediated the concurrent relationship between childhood sexual abuse and levels of depression, confidence, and locus of control, and accounted for the relationship between abuse and levels of overall eating pathology ten years later, including dieting behavior, bulimia and food preoccupation, and oral control, as well as the extent to which the participants experienced subsequent revictimization. Results indicate that attachment style likely accounts for at least some of the diversity of effects experienced by childhood sexual abuse survivors.

description: In humans, alcohol consumption commonly precedes and co-occurs with cocaine use, suggesting that alcohol may act as a significant catalyst for the initiation and maintenance of cocaine use. Although the bases for these interactions are unknown, it is possible that alcohol influences the likelihood to begin, maintain and reinitiate cocaine use by modulating cocaine reinforcement. Therefore, the purpose of the present assessments was to examine alcohol's ability to modulate cocaine reinforcement using a drug abuse model (i.e., the conditioned place preference design) sensitive to drug interactions similar to those that occur in the human cocaine using population. Specifically, Experiment 1 assessed the effects of alcohol preexposure (1.5 g/kg) on place preferences conditioned by 20 mg/kg cocaine. Experiment 2a and 2b examined the effects of alcohol (0.5g/kg) on place preferences conditioned by low (2.5 and 5 mg/kg; Experiment 2a), intermediate (20 mg/kg; Experiment 2b) and high (30 and 40 mg/kg; Experiment 2b) doses of cocaine when these two compounds are administered concurrently. Finally, Experiment 3 assessed the ability of alcohol (0.5 and 1.0 g/kg) to reinstate place preferences conditioned by 20 mg/kg cocaine. In Experiment 1, cocaine's ability to condition a place preference was not altered after animals were preexposed to alcohol, suggesting that alcohol history produced no measurable change in cocaine's reinforcing effects. In Experiment 2a and 2b, however, alcohol potentiated the place conditioning effects of 5 mg/kg cocaine, had no effect on place preferences produced by 20 mg/kg cocaine and attenuated place preferences conditioned by 30 and 40 mg/kg cocaine. These data indicate that alcohol produced a bi-directional modulation in cocaine reinforcement that was selective to cocaine dose. Finally, in Experiment 3, priming injections of 0.5 and 1.0 g/kg alcohol failed to reinstate cocaine place preferences previously conditioned by 20 mg/kg cocaine, suggesting that alcohol did not renew the salience of cocaine reinforcement in animals with previous cocaine experience. Together, these findings suggest that within the CPP design, only the concurrent administration of cocaine and alcohol produced measurable changes in cocaine's reinforcing effects.

description: In this paper we address the possibility of horizontal foreclosure in markets for complementary services (software) where the consumption value of durables (hardware) depends on the availability of software. Horizontal foreclosure occurs when a hardware firm merges with a software firm and the integrated firm ceases to supply compatible software for a rival technology. We find that horizontal foreclosure can be an equilibrium outcome where both the merger and compatibility decisions are part of a multistage game which permits the foreclosed firm to play a number of counter- strategies. Moreover, foreclosure may result in monopolization of the hardware market. We find that the foreclosure equilibrium is inefficient: total surplus would be higher without foreclosure.

description: In a recent work, signatures of a pair of Majorana bound states (MBS) were found in a new experimental platform formed by EuS islands deposited on top of a gold surface which was made superconducting through proximity coupling to a superconductor. In this work, we provide a theoretical understanding for how MBS can be formed in EuS/Au/superconductor heterostructures. We focus on the strip geometry where a narrow ferromagnetic strip is deposited on a planar structure. We first explicitly map out the topological phase diagram of the EuS/Au/superconductor heterostructure using the lattice Green's function method. Importantly, we find that the chemical potential step between the region with and without EuS covering is a crucial ingredient for the creation of MBS of this set-up. Next, we focus on the Bogoliugov quasi-particles that are bound to the region under the EuS by Andreev reflections from the surrounding superconductors. Moreover, we obtain the topological regimes analytically using the scattering matrix method. Notably, we confirm that the normal reflections induced by the chemical potential step are essential for creating finite topological regimes. Furthermore, the area of the topological regimes shows periodic oscillation as a function of chemical potential as well as the sample width.
