description: The diagrammatic t-matrix approximation has often been adopted to describe a dilute Fermi gas. This approximation, originally considered by Galitskii for a repulsive inter-particle interaction (Galitskii-1958), has later been widely utilized for an attractive Fermi gas to describe the BCS-BEC crossover from strongly overlapping Cooper pairs in weak coupling to non-overlapping composite bosons in strong coupling. Several variants of the $t$-matrix approximation have been considered in the literature, which are distinguished by the degree of self-consistency allowed in the building blocks of the diagrammatic structure. Here, we perform a systematic and comparative study of all possible variants on the degree of self-consistency for the $t$-matrix approximation in an attractive Fermi gas, which enables us to confront their outcomes for thermodynamic and dynamical quantities on the same footing in an unbiased way. For definiteness, only the normal phase above the superfluid critical temperature is considered. The dispute that can be raised in this context, about the adequateness of introducing progressive degrees of self-consistency over and above the non-self-consistent $t$-matrix approximation for an attractive Fermi gas, parallels the recent interest in the literature on assessing the importance of various degrees of self-consistency in the context of semiconductors and insulators.

description: We show that in the neighborhood of the tripling bifurcation of a periodic orbit of a Hamiltonian flow or of a fixed point of an area preserving map, there is generically a bifurcation that creates a ``twistless'' torus. At this bifurcation, the twist, which is the derivative of the rotation number with respect to the action, vanishes. The twistless torus moves outward after it is created, and eventually collides with the saddle-center bifurcation that creates the period three orbits. The existence of the twistless bifurcation is responsible for the breakdown of the nondegeneracy condition required in the proof of the KAM theorem for flows or the Moser twist theorem for maps. When the twistless torus has a rational rotation number, there are typically reconnection bifurcations of periodic orbits with that rotation number.

description: The purpose of this research study was to examine the effectiveness of two digital tools: a virtual number line (Jumper Tool); and a dynamic hundreds chart (Morphing Chart) in improving children’s understanding of multiplication and number sense. One hundred twenty-two third grade students (69 girls), ages ranging from 8 years-0 months to 10 years-3 months (M = 8.88 years, SD = 0.44) from three New York City public elementary schools, were recruited to participate in the study. Participants were randomly assigned to one of two math treatment groups or a reading control group. Students in the Jumper group used a number line tool, while those in the Morphing group used a morphing hundreds chart. Children’s number sense ability and understanding of multiplication were tested at pre- and posttest to examine group differences. Researchers recorded children’s strategy use and a back-end logging system collected data on accuracy during treatment sessions. No group differences across the Jumper, Morphing, or Control groups were found at posttests when controlling for pretest performance. However, the presence of a tool (Jumper or Morphing) during treatment sessions resulted in better performance than the absence of a tool (No Tool). Strategy use had a significant effect on session performance as well. Fast and Tool Use responses performed better than Delayed responses. Additionally, Fast responses were more likely to be correct than those who used an Advanced strategy.  Finally, the results indicated that Fast responses were predictive of children’s performance on multiplication facts and number sense tests and Tool use was predictive of performance on multiplication facts. These findings suggest that having a tool, Jumper or Morphing, helped children solve multiplication problems and that tool use is related to superior mastery of multiplication facts.

description: This study examines whether differences in parental education are reflected in differences in children’s scores on cognitive tests, drawing attention to the role of family context in educational outcomes. The primary focus is on the parental education/testscore gradient in New Zealand, although the study also presents comparative results for other OECD countries. Separate analyses are carried out for subgroups of children in New Zealand defined by immigrant status, gender and family type, and for children of New Zealand parents living in Australia. To gain a better understanding of the factors associated with the gradient, the study analyses the statistical contribution of five broadly defined sets of educational inputs – student characteristics, household characteristics, household educational resources, student-school interactions and school characteristics (the components of which are listed in the glossary and in Table 10, and described in Appendix 1)

description: Over the several decades, rent-burdens for low-and moderate-income New Yorkers have continued to increase, leading to demands for more affordable housing. This trend has become only worse with citywide gentrification over time. Federal, state and city governments have implemented various subsidized housing programs to support more affordable housing units. One of the key determinants in stocks of affordable units is the opt-out rate, which is dependent on property owners’ decision to leave the program after the contract term. Thus, information on what factors make owners stay in or leave subsidy programs can be useful in policy-makers’ effort to preserve affordable housing units. This study examines factors associated with gentrification and their relationship with opt-out rate of subsidized rental housing programs. Through a statistical logistic regression model, this study investigated if factors associated with gentrification, such as median income, nearby property prices and other neighborhood conditions, have bigger impacts on owner’ decisions to stay or leave subsidy programs than other factors that generally affect property prices or owner’s decision to change property prices. The results suggested that gentrification predictors have substantial impacts on property’s opting-out, comparable to other control factors. The findings of this study highlights the importance of using extensive neighborhood data to develop an effective affordable housing preservation strategy.

description: Introduction: Third-generation antiepileptic drugs have seemingly failed to improve the global figures of seizure control and can still be regarded as symptomatic treatments. Quantitative structure–activity relationships (QSAR) can be used to guide hit-to-lead and lead optimization projects and applied to the large-scale virtual screening of chemical libraries. Areas covered: In this review, the authors cover reports on QSAR models related to antiepileptic drugs and drug targets in epilepsy, analyzing whether they refer to classic or non-classic QSAR and if they apply QSAR as a descriptive or predictive approach, among other considerations. The article finally focuses on a more detailed discussion of those predictive studies which include some sort of experimental validation, i.e. papers in which the reported models have been used to identify novel active compounds which have been tested in vitro and/or in vivo. Expert opinion: There are significant opportunities to apply the QSAR methodology to assist the discovery of more efficacious antiepileptic drugs. Considering the intrinsic complexity of the disorder, such applications should focus on state-of-the-art approximations (e.g. systemic, multi-target and multi-scale QSAR as well as ensemble and deep learning) and modeling the effects on novel drug targets and modern screening tools.

description: Background: Climbing is an intricate sport composed of various disciplines, holds, styles, distances between holds, and levels of difficulty. In highly skilled climbers the potential for further strength-specific adaptations to increase performance may be marginal in elite climbers. With an eye on the upcoming 2024 Paris Olympics, more climbers are trying to maximize performance and improve training strategies. The relationships between muscular strength and climbing performance, as well as the role of strength in injury prevention, remain to be fully elucidated. This narrative review seeks to discuss the current literature regarding the effect of resistance training in improving maximal strength, muscle hypertrophy, muscular power, and local muscular endurance on climbing performance, and as a strategy to prevent injuries.

Main Body: Since sport climbing requires exerting forces against gravity to maintain grip and move the body along the route, it is generally accepted that a climber`s absolute and relative muscular strength are important for climbing performance. Performance characteristics of forearm flexor muscles (hang-time on ledge, force output, rate of force development, and oxidative capacity) discriminate between climbing performance level, climbing styles, and between climbers and non-climbers. Strength of the hand and wrist flexors, shoulders and upper limbs has gained much attention in the scientific literature, and it has been suggested that both general and specific strength training should be part of a climber`s training program. Furthermore, the ability to generate sub-maximal force in different work-rest ratios has proved useful, in examining finger flexor endurance capacity while trying to mimic real-world climbing demands. Importantly, fingers and shoulders are the most frequent injury locations in climbing. Due to the high mechanical stress and load on the finger flexors, fingerboard and campus board training should be limited in lower-graded climbers. Coaches should address, acknowledge, and screen for amenorrhea and disordered eating in climbers.

Conclusion: Structured low-volume high-resistance training, twice per week hanging from small ledges or a fingerboard, is a feasible approach for climbers. The current injury prevention training aims to increase the level of performance through building tolerance to performance-relevant load exposure and promoting this approach in the climbing field.
Nijenhuis geometry II: Left-symmetric algebras and linearization problem for Nijenhuis operators

description: A field of endomorphisms $R$ is called a Nijenhuis operator if its Nijenhuis torsion vanishes. In this work we study a specific kind of singular points of $R$ called points of scalar type. We show that the tangent space at such points possesses a natural structure of a left-symmetric algebra (also known as pre-Lie or Vinberg-Kozul algebras). Following Weinstein's approach to linearization of Poisson structures, we state the linearisation problem for Nijenhuis operators and give an answer in terms of non-degenerate left-symmetric algebras. In particular, in dimension 2, we give classification of non-degenerate left-symmetric algebras for the smooth category and, with some small gaps, for the analytic one. These two cases, analytic and smooth, differ. We also obtain a complete classification of two-dimensional real left-symmetric algebras, which may be an interesting result on its own. This work is the second part of a series of papers on Nijenhuis Geometry started with arXiv:1903.04603
Quantum field theory with and without conical singularities: Black holes with cosmological constant and the multi-horizon scenario

description: Boundary conditions and the corresponding states of a quantum field theory depend on how the horizons are taken into account. There is ambiguity as to which method is appropriate because different ways of incorporating the horizons lead to different results. We propose that a natural way of including the horizons is to first consider the Kruskal extension and then define the quantum field theory on the Euclidean section. Boundary conditions emerge naturally as consistency conditions of the Kruskal extension. We carry out the proposal for the explicit case of the Schwarzschild-de Sitter manifold with two horizons. The required period $β$ is the interesting condition that it is the lowest common multiple of $2π$ divided by the surface gravity of both horizons. Restricting the ratio of the surface gravity of the horizons to rational numbers yields finite $β$. The example also highlights some of the difficulties of the off-shell approach with conical singularities in the multihorizon scenario; and serves to illustrate the much richer interplay that can occur among horizons, quantum field theory and topology when the cosmological constant is not neglected in black hole processes.

description: Volunteered geographic information (VGI) contains valuable field observations that represent the spatial distribution of geographic phenomena. As such, it has the potential to provide regularly updated low-cost field samples for predictively mapping the spatial variations of geographic phenomena. The predictive mapping of geographic phenomena often requires representative samples for high mapping accuracy, but samples consisting of VGI observations are often not representative as they concentrate on specific geographic areas (i.e. spatial bias) due to the opportunistic nature of voluntary observation efforts. In this article, we propose a representativeness-directed approach to mitigate spatial bias in VGI for predictive mapping. The proposed approach defines and quantifies sample representativeness by comparing the probability distributions of sample locations and the mapping area in the environmental covariate space. Spatial bias is mitigated by weighting the sample locations to maximize their representativeness. The approach is evaluated using species habit suitability mapping as a case study. The results show that the accuracy of predictive mapping using weighted sample locations is higher than using unweighted sample locations. A positive relationship between sample representativeness and mapping accuracy is also observed, suggesting that sample representativeness is a valid indicator of predictive mapping accuracy. This approach mitigates spatial bias in VGI to improve predictive mapping accuracy.

description: This dissertation examines three health insurance eligibility policies and their impact on reproductive health outcomes for low-income women of reproductive age. The first paper examines the effects of expanded eligibility for Medicaid under the Affordable Care Act (ACA), on fertility among low-income women of childbearing age. The second paper explores the effect of presumptive eligibility policies in Medicaid for pregnant women on access to prenatal care and health insurance coverage. Finally, the third paper exploits state-level differences in eligibility for public versus private insurance under the ACA, and the effects on perinatal coverage patterns, childbirth outcomes, and access to care.

The Impact of Belt and Road Initiative on Tourism Industry around Asian Countries
Creators: name: Arshad, Hamza

description: More than 60 countries and 4.4 billion people—one-third of global economic output, 40% of global trade, and more than 60% of the world's population—make the BRI a cultural route with access to the world's top tourist resources, including 80% of global cultural heritage. BRI links popular tourism destinations. COVID-19 shook China's economy two months ago. The closure harmed tourism. OBOR's impact on Asian tourism will be examined. We lack economic data to examine covid-19 this year. We'll prioritize One Belt, One Road. This study explores Asian tourism and OBOR. This year's covid-19 research requires economic data. Even if the Belt and Road nations are part of a low-end and poor tourist value chain with inadequate infrastructure, unprofessional tourism practitioners, and low service standards, policy help and political collaboration make it easier to produce an economic boom. BRI affects tourism differently. Geography has two causes. BRI countries differ in trade and investment openness. Second, local tourism and transit networks influence foreign travel. Our study has shortcomings. First, our pieces did not address all ways BRI impacts tourism. Tourists and BRI require further study. The report says BRI's favorable influence on international travel should stimulate tourist collaboration. First, tourism experts should join policy and financial assistance organizations like the Shanghai Cooperation Organization, Asian Infrastructure Investment Bank, Silk Road Fund, and others. Cross-border tourist cooperation zones, transit, and accessibility are needed in belt and road border areas. To improve local tourism, propose visa-free travel and visa-on-arrival policies with several nations and 24-hour customs clearance.
The perturbative QCD predictions for the decay B^{0}_{s}\rightarrow SS(a_{0}(980),f_{0}(980),f_{0}(500))

description: In this work, we calculate the branching ratios and CP violations of the B^{0}_{s}\rightarrow a_{0}(980)a_{0}(980) decay modes with both charged and neutral a_{0}(980) mesons and B^{0}_{s}\rightarrow f_{0}(980)(f_{0}(500))f_{0}(980)(f_{0}(500)) for the first time in the pQCD approach. Considering the recent observation of the BESIII collaboration that provide a direct information about the constituent two-quark components in the corresponding a_{0}(980) wave functions, we regard the scalar mesons a_{0}(980), f_{0}(980) and f_{0}(500) as the q\bar{q} quark component in our present work, and then make predictions of these decay modes. The branching ratios of our calculations are at the order of the 10^{-4}\sim10^{-6} when we consider the mixing scheme. We also calculate the CP violation parameters of these decay modes. The relatively large branching ratios make it easily to be tested by the running LHC-b experiments, and it can help us to understand both the inner properties and the QCD behavior of the scalar meson.

description: This study computes the potential energy curves of the X1Σ+, A1Π, B1Δ, C1Σ+, and D1Π states of AlO+ cation and the transition dipole moments between them. The orders of the rotationless radiative lifetimes are 10–100 μs for the A1Π state, 1–1000 ms for the B1Δ state, 10 ns for the first well and 100 ns for the second well of the C1Σ+ state, and 1 μs for the D1Π state. Emissions of the B1Δ–A1Π and D1Π–C1Σ+ systems are so weak that they are hardly measured via spectroscopy, the emissions of the C1Σ+–X1Σ+, C1Σ+–A1Π, and D1Π–X1Σ+ systems are so strong that they can be detected readily, and emissions of the A1Π–X1Σ+ and D1Π–A1Π systems can be observed through spectroscopy only by a significant effort. There is a strong great similarity between spontaneous emissions of the A1Π–X1Σ+ system of the AlO+ cation and the A2Π–X2Σ+ system of the AlO radical. The emissions of the A2Π–X2Σ+ system of the AlO radical have been measured in outer space Therefore, it is highly possible that the emissions of the A1Π–X1Σ+ system of the AlO+ cation can be detected in the astrophysical media.

description: Diagonally implicit Runge-Kutta methods with an explicit first stage (ESDIRK--methods) have usually order reduction if they are applied on stiff ODEs such as the example of Prothero and Robinson. It can be observed that the numerical order of convergence drops down to the stage order, which is limited by two. In this paper we analyse the Prothero-Robinson example and derive new order conditions to avoid order reduction.
New third and fourth order ESDIRK--methods are created. The new schemes are applied on the Prothero--Robinson example and on an index-2 DAE. Numerical examples show that the new methods have better convergence properties than usual ESDIRK methods.

Scar and Antiscar Quantum Effects in Open Chaotic Systems

Year: 1998
Subjects: subject: Chaotic Dynamics (nlin.CD)
subject: FOS: Physical sciences

description: We predict and numerically observe strong periodic orbit effects in the properties of open quantum systems with a chaotic classical limit. Antiscars lead to a large number of exponentially narrow resonances when the opening is located on a short unstable orbit of the closed system; the probability to remain in the system at long times is thus exponentially enhanced over the random matrix theory prediction. The distribution of resonance widths and the probability to remain are quantitatively given in terms of only the stability matrix of the orbit on which the opening is placed. The long-time remaining probability density is non-trivially distributed over the available phase space; it can be enhanced or suppressed near orbits other than the one on which the lead is located, depending on the periods and classical actions of these other orbits. These effects of the short periodic orbits on quantum decay rates have no classical counterpart, and first appear on times scales much larger than the Heisenberg time of the system. All the predictions are quantitatively compared with numerical data.

description: Fractals are patterns that repeat at many magnifications. These intricate patterns are found throughout nature, ranging from clouds, rivers and lightning through to our brains, blood vessels and lungs. Due to their prevalence in nature and their growing impact on cultures around the world, fractals have assumed a rapidly expanding role across the sciences and arts. In this talk, I will explore some of the intriguing properties of fractals by taking a meandering walk through the research disciplines I have worked in. These will include nano-electronic circuits, Antarctic ice-shelves, brain structure and artworks. I hope to show a common theme - that quantification of their underlying fractal geometry provides an enhanced understanding well beyond the traditional qualitative views of these diverse systems.

In this framework, we identify and calculate the dominant one-loop radiative corrections to the tree-level mass matrix of the light neutrinos. The interesting feature is that both the tree-level and the one-loop contributions to the light-neutrino mass matrix are quadratic in the Yukawa couplings, with the effect that the one-loop contribution is smaller than the tree-level one mainly because of the one-loop factor $(16π^2)^{-1}$. We also point out the possibility of generating radiatively--in this framework--the ratio of solar over atmospheric neutrino mass-squared differences, as needed for the large-mixing-angle MSW solution of the solar-neutrino problem.

Critical Behavior of Period Doublings in Coupled Inverted Pendulums

description: We study the critical behaviors of period doublings in N (N=2,3,4,...) coupled inverted pendulums by varying the driving amplitude $A$ and the coupling strength $c$. It is found that the critical behaviors depend on the range of coupling interaction. In the extreme long-range case of global coupling, in which each inverted pendulum is coupled to all the other ones with equal strength, the zero-coupling critical point and an infinity of critical line segments constitute the same critical set in the $A-c$ plane, independently of $N$. However, for any other nonglobal-coupling cases of shorter-range couplings, the structure of the critical set becomes different from that for the global-coupling case, because of a significant change in the stability diagram of periodic orbits born via period doublings. The critical scaling behaviors on the critical set are also found to be the same as those for the abstract system of the coupled one-dimensional maps.

description: We consider statistics of the passive scalar on distances much larger than the pumping scale. Such statistics is determined by statistics of Lagrangian contraction that is by probabilities of initially distant fluid particles to come close. At the Batchelor limit of spatially smooth velocity, the breakdown of scale invariance is established for scalar statistics.

description: Early damage detection and classification by condition monitoring systems is crucial to enable predictive maintenance of manufacturing systems and industrial facilities. The data analysis can be improved by applying machine learning algorithms and fusion of data from heterogeneous sensors. The paper (see ) presents an approach for a step-wise integration of classifications gained from vibration and acoustic emission sensors, in order to combine the information from signals acquired in the low and high frequency range. A test rig comprising a drive train and bearings with small artificial damages is used for acquisition of experimental data. The results indicate that an improvement of damage classification can be obtained using the proposed algorithm of combining classifiers for vibrations and acoustic emission. This dataset contains vibration data as well as acoustic emission data recorded on a rotating drive train. For vibration measurements, the setup is instrumented with ICP accelerometers (PCB 607A11, 100 mV/g) at the bearing holder frame of the motor and the bearing holder frame of the shaft. Both vibrational sensors are digitized by a DT 9837A USB-DAQ from (Measurement Computing GmbH). This 4-channel signal analyzer is equipped with a 24-bit ADC, that supports sample rates of up to 100 kSPS and is well suited for the vibration measurements. Acoustic emission signals (AE) are acquired by a piezo transducer (Vallen VS30V, 20 kHz – 80 kHz) connected to an AEP5 pre-amplifier for signal conditioning. These signals are digitized with an USB oscilloscope (PicoScope 2204A). This entry-level 2-channel oscilloscope features an 8-bit ADC with sample rates of up to 100 MSPS with an analog bandwidth of 10 MHz.

description: Out of Pocket expenditure on medicines constitutes more than 50% of healthcare expenditure in India. The poor are most affected as branded medicines are expensive and treatments involving the use of such medicines pushes them further into poverty.To address this issue government central government started Jan Aushadhi (Medicine for the masses) programme in 2008 with the objective of providing quality medicines at affordable prices. The programme envisaged the sale of generic medicines through stores to be called "Pradhan Mantri Janaushadhi Kendras” in various districts of the country.This paper seeks to examine and assess the successes and failures of the government initiatives so far, impact on the beneficiaries, challenges in execution and the way ahead.
title: Towards upper bounding the variance of the demixing estimate of a geometry based Independent Component Analysis algorithm - Technical Report

description: For the Independent Component Analysis(ICA) algorithm (using a geometric approach) given in [1], we provide a probabilistic upper bound on the Euclidean error of constituents of the demixing matrix estimate resulting from unmixed input, under the condition that the algorithm converges to the global optimum, and derive an asymptotic bound on the expected squared error for large sample sizes from it. This error bound is found to be of order $O(N^{-2 + 2beta})$, where $N$ is the sample size and $beta in (0,1)$ is chosen arbitrarily. The result can be used to establish the asymptotic behaviour of the variance of the demixing matrix estimate for arbitrarily linearly mixed independent inputs.
The Effects of Imitation Instruction Using a Mirror on the Emergence of Duplicative Responses by Preschool Students Diagnosed with Developmental Delays

description: Using pre- and post-intervention non-concurrent multiple probe designs across participants, I conducted 2 experiments that tested the effects of imitation instruction using a mirror on the emergence of both basic and advanced forms of generalized imitation (GI) involving physical actions with preschool students diagnosed with developmental delays. Experiment I was first conducted to test the effectiveness and efficiency of using a mirror to induce GI with 4 young developmentally delayed preschoolers. The dependent variable was the number of untaught, unconsequated basic physical imitative responses (e.g., nodding head) emitted by participants prior to and following intervention conditions while directly facing the experimenter. The independent variable involved teaching basic imitative actions (e.g., clapping hands) while looking at an adult perform the actions in a mirror until a mastery criterion was met. The results of Experiment I showed that a functional relationship was demonstrated between mastering the imitation of basic physical actions using a mirror and the emergence of GI for all 4 participants. Experiment II was then conducted to further examine the effectiveness and efficiency of using a mirror to induce more advanced forms of GI with older preschoolers diagnosed with developmental delays as well as examine the effects of the absence and presence of advanced GI on the rate of participant learning after an adult provided a how-to demonstration. The primary dependent variable was the number of instructional sessions required for each participant to meet a mastery criterion on a novel dressing skill before and after the participants acquired GI. The second dependent variable was participant responding during block structure duplication and transcription tasks before and after the participants acquired all advanced forms of GI at mastery level. The independent variable was the induction and/or presence of advanced, mastery level GI using mirror imitation instruction across bodily actions (e.g., gross motor, fine motor, oral motor, and multiple-step motor actions). The results of Experiment II showed that the presence of mastery level GI accelerated learning for all 4 participants, which may have facilitated the participants' capability of learning through demonstration.

description: In the Next-to-Minimal Supersymmetric Standard Model with the inverse seesaw mechanism to generate neutrino masses, the lightest sneutrino may act as a feasible dark matter candidate in vast parameter space. In this case, the smallness of the leptonic unitarity violation and the recent XENON-1T experiment can limit the dark matter physics. In particular, they set upper bounds of the neutrino Yukawa couplings $λ_ν$ and $Y_ν$. We study such effects by encoding the constraints in a likelihood function and carrying out elaborated scans over the parameter space of the theory with the Nested Sampling algorithm. We show that these constraints are complementary to each other in limiting the theory, and in some cases, they are very strict. We also study the impact of the future LZ experiment on the theory.

description: Mellin moments of off-forward distribution functions are even polynomials of the skewedness parameter. This constraint, called polynomiality property, follows from Lorentz- and time-reversal invariance. We prove that the unpolarized off-forward distribution functions in the chiral quark-soliton model satisfy the polynomiality property. The proof is an important contribution to the demonstration that the description of off-forward distribution functions in the model is consistent. As a byproduct of the proof we derive explicit model expressions for moments of the D-term and compute the first coefficient in the Gegenbauer expansion for this term.
