description: Second order approximate ancillaries have evolved as the primary ingredient for recent likelihood development in statistical inference. This uses quantile functions rather than the equivalent distribution functions, and the intrinsic ancillary contour is given explicitly as the plug-in estimate of the vector quantile function. The derivation uses a Taylor expansion of the full quantile function, and the linear term gives a tangent to the observed ancillary contour. For the scalar parameter case, there is a vector field that integrates to give the ancillary contours, but for the vector case, there are multiple vector fields and the Frobenius conditions for mutual consistency may not hold. We demonstrate, however, that the conditions hold in a restricted way and that this verifies the second order ancillary contours in moderate deviations. The methodology can generate an appropriate exact ancillary when such exists or an approximate ancillary for the numerical or Monte Carlo calculation of $p$-values and confidence quantiles. Examples are given, including nonlinear regression and several enigmatic examples from the literature.

Subjects: subject: Networking and Internet Architecture (cs.NI)

description: Multicast plays an important role in implementing the group communications in bandwidth scarce multihop mobile ad hoc networks. However, due to the dynamic topology of MANETs it is very difficult to build optimal multicast trees and maintaining group membership, making even more challenging to implement scalable and robust multicast in Mobile Ad hoc Networks (MANET). A scalable and energy efficient location aware multicast algorithm, called SEELAMP, for mobile ad hoc networks is presented in the paper that is based on creation of shared tree using the physical location of the nodes for the multicast sessions. It constructs a shared bi-directional multicast tree for its routing operations rather than a mesh, which helps in achieving more efficient multicast delivery. The algorithm uses the concept of small overlapped zones around each node for proactive topology maintenance with in the zone. Protocol depends on the location information obtained using a distributed location service, which effectively reduces the overheads for route searching and shared multicast tree maintenance. In this paper a new technique of local connectivity management is being proposed that attempts to improve the performance and reliability. It employs a preventive route reconfiguration to avoid the latency in case of link breakages and to prevent the network from splitting.

DETERMINANTS OF LOAN REPAYMENT AMONG RURAL YOUTH  GROUPS: THE CASE OFSOUTH ARI WOREDA, SOUTH OMO ZONE OF ETHIOPIA
Creators: name: ALEMU TEKA KALI
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: Poverty and youth unemployment is a serious problem of developing countries like Ethiopia.
But, in recent years government programs, NGO’s and Microfinance institutions are trying
to alleviate the problem by accessing credit to the unemployed youth and poor peoples who
lives in urban and rural areas. However, failure by rural youth groups to repay their loan on
time  or  to  repay  them  at  all  has  been  a  serious  problem  faced  by  lending  government
programs  and  microfinance  institutions.Therefore, the  major  aim  of  this  study  is  to
empirically examine factors determining loan repayment among rural youth business groups;
in case of South Ari Woreda, South Omo zone of Ethiopia. Both descriptive and econometric
regression  models  were  used  to  analyze  collected  data.  Descriptive  statistics  were  used  to
summarize and describe the socio-economic, institutional & business type characteristics of
the  respondents.  Moreover,  chi-square  test  and  t-test  analysis  were  used  to  compare
defaulters  and  non-defaulters  in  case  of  different  explanatory  variables.  Two  limit
Tobiteconometric regression model was used to identify factors determining loan repayment
of  rural  youth  business  groups.  The  result indicated that  out  of  13 explanatory  variables,
Loan  diversion influence  loan  repayment  of  rural  youth  business  groups significantly  and
negatively.WhileTeam work sprite of the groups, Business experience of the group, Provision
of manufacturing and selling sit, Loan supervision, Suitable repayment and Loan releasing
time line were found to be the most significant variables contributing to loan repayment of
rural  youth  groups  positively.  Thus,  the  study  suggests  that,  the  identified  significant
variables  to  be  a  stepping  stone  to  further  interventions  for  Government  bodies,  financial
institutions, & stakeholders so as to work together to significantly decrease loan defaulting

We cope together : predictors and consequences of social support mobilization
Creators: name: Pow, Jessica Leanne
Publisher: name: University of British Columbia

description: Perceptions of support availability are important for well-being. However, little is known about support mobilization. Questions remain about when support is likely to be sought and provided and why support receipt is not always linked to improvements in well-being. This research examined support mobilization in three intensive longitudinal studies. Study 1 categorized appraisals of threat during stressful situations based on whether they were agentic (self-focused) or communal (other-focused). A model linking stressors, appraisals of agentic and communal threat, and support mobilization was examined. Consistent with expectations, increases in agentic threat were associated with increases in support seeking and decreases in support provision. In contrast, increases in communal threat were associated with increases in support seeking and provision. Study 2 extended results of Study 1 by examining whether the associations between threats and support are moderated by extraversion and agreeableness, personality dimensions previously implicated in the support process. At times when participants experienced increases in agentic threat, those higher in extraversion increased their support seeking and decreased their support provision to a greater extent than those lower in extraversion. At times when participants experienced increases in communal threat, those higher in agreeableness increased their support seeking and provision to a greater extent than those lower in agreeableness. Study 3 examined the associations between pain and several types of emotional support mobilization from partners to individuals diagnosed with rheumatoid arthritis (RA). Those with RA provided reports on pain mornings and evenings across one week. Both partners also reported three types of emotional support: esteem, solicitous, and negative from the partners to the person with RA. Pain tended to increase across the day following increases in negative support receipt and solicitous support provision. Pain tended to decrease across the day when partners reported increased levels of esteem support provision. This research adds to the growing body of literature on the support mobilization process, building knowledge on factors that might lead people to seek and provide support during stress. This research also unpacks different types of emotional support and sheds light on the types that may be helpful in chronic pain contexts.
Taiwanese Elementary Students’ Creativity, Creative Personality, and Learning Styles: An Exploratory Study

description: In the field of education, creativity has been viewed as an important ability for children’s development. The recognition of different learning styles is also important for both teachers and learners. Although a handful of studies have examined the relationship between creativity and personality, or between creativity and cognitive style, few have assessed creativity, creative personality, and learning preferences simultaneously. Thus, the purpose of this study is to explore possible linkages between these three variables in Taiwanese children. More centrally, the research empirically probes into relating the personality and cognitive-style profiles of children, with creativity as a byproduct. The major finding of this research is that creative personality is positively related to creativity. Additionally, the results of multiple regression indicated that, among the variables studied, creative personality is the only valid variable for the prediction of creativity. Unexpectedly, none of the learning dimensions served as good predictors of creativity. Dans le domaine de l’éducation, on perçoit la créativité comme capacité importante au développement des enfants. Il est également important, tant pour les enseignants que les élèves, que l’on reconnaisse différents styles d’apprentissage. Si une poignée d’études se sont penchées sur le rapport entre la créativité et la personnalité, ou la créativité et le style cognitif, peu d’études ont porté à la fois sur la créativité, la personnalité créative et les préférences en apprentissage. L’objectif de cette étude est justement d’explorer les liens potentiels entre ces trois variables chez des enfants taiwanais. Plus précisément, cette recherche empirique met en lien la personnalité et le style cognitif des enfants avec la créativité comme sous-produit. Les conclusions indiquent qu’une personnalité créative est en corrélation positive avec la créativité. De plus, les résultats d’une analyse de régression multiple indiquent que parmi les variables étudiées, la personnalité créative est la seule avec un caractère prédicteur valide pour la créativité. Contrairement aux attentes, aucune dimension d’apprentissage n’a servi de bon prédicteur de créativité.

description: We discuss generic smooth maps from smooth manifolds to smooth surfaces, which we call "Morse 2-functions", and homotopies between such maps. The two central issues are to keep the fibers connected, in which case the Morse 2-function is "fiber-connected", and to avoid local extrema over 1-dimensional submanifolds of the range, in which case the Morse 2-function is "indefinite". This is foundational work for the long-range goal of defining smooth invariants from Morse 2-functions using tools analogous to classical Morse homology and Cerf theory.

description: The harnessing of plasmon-induced hot carriers promises to open new avenues for the development of clean energies and chemical catalysis. The extraction of carriers before thermalization and recombination is of primordial importance to obtain appealing conversion yields. Here, hot carrier injection in the paradigmatic Au-TiO$_{2}$ system is studied by means of electronic and electron-ion dynamics. Our results show that pure electronic features (without considering many-body interactions or dissipation to the environment) contribute to the electron-hole separation stability. These results reveal the existence of a dynamic contribution to the interfacial potential barrier (Schottky barrier) that arises at the charge injection pace, impeding electronic back transfer. Furthermore, we show that this charge separation stabilization provides the time needed for the charge to leak to capping molecules placed over the TiO$_{2}$ surface triggering a coherent bond oscillation that will lead to a photocatalytic dissociation. We expect that our results will add new perspectives to the interpretation of the already detected long-lived hot carrier lifetimes, their catalytical effect, and concomitantly to their technological applications.
IR spectroscopy of COmosphere dynamics with the CO first overtone band

description: We discuss observations of the weak first overtone CO absorption band near 2300 nm with the U.S. National Solar Observatory Array Camera (NAC), a modern mid-infrared detector. This molecular band provides a thermal diagnostic that forms lower in the atmosphere than the stronger fundamental band near 4600 nm. The observed center-to-limb increase in CO line width qualitatively agrees with the proposed higher temperature shocks or faster plasma motions higher in the COmosphere. The spatial extent of chromospheric shock waves is currently at or below the diffraction limit of the available C0 lines at existing telescopes. Five minute period oscillations in line strength and measured Doppler shifts are consistent with the p-mode excitation of the photospheric gas. We also show recent efforts at direct imaging at 4600 nm. We stress that future large-aperture solar telescopes must be teamed with improved, dynamic mid-infrared instruments, like the NAC, to capitalize on the features that motivate such facilities.

description: With the idea to find geometric formulations of particle physics we investigate the predictions of a three dimensional generalisation of the Sine-Gordon model, very close to the Skyrme model and to the Wu-Yang description of Dirac monopoles. With three rotational degrees of freedom of spatial Dreibeins we formulate a Lagrangian and confront the predictions to electromagnetic phenomena. Stable solitonic excitations we compare with the lightest fundamental electric charges, electrons and positrons. Two Goldstone bosons we relate to the properties of photons. These particles are characterised by three topological quantum numbers, which we compare to charge, spin and photon number. Finally we conjecture some ideas for further comparisons with experiments.

description: Advances in communications, storage and computational technology allow significant quantities of data to be collected and processed by distributed devices. Combining the information from these endpoints can realize significant societal benefit but presents challenges in protecting the privacy of individuals, especially important in an increasingly regulated world. Differential privacy (DP) is a technique that provides a rigorous and provable privacy guarantee for aggregation and release. The Shuffle Model for DP has been introduced to overcome challenges regarding the accuracy of local-DP algorithms and the privacy risks of central-DP. In this work we introduce a new protocol for vector aggregation in the context of the Shuffle Model. The aim of this paper is twofold; first, we provide a single message protocol for the summation of real vectors in the Shuffle Model, using advanced composition results. Secondly, we provide an improvement on the bound on the error achieved through using this protocol through the implementation of a Discrete Fourier Transform, thereby minimizing the initial error at the expense of the loss in accuracy through the transformation itself. This work will further the exploration of more sophisticated structures such as matrices and higher-dimensional tensors in this context, both of which are reliant on the functionality of the vector case.

description: We show that in the new topological-insulator compound Bi_{1.5}Sb_{0.5}Te_{1.7}Se_{1.3} one can achieve a surfaced-dominated transport where the surface channel contributes up to 70% of the total conductance. Furthermore, it was found that in this material the transport properties sharply reflect the time dependence of the surface chemical potential, presenting a sign change in the Hall coefficient with time. We demonstrate that such an evolution makes us observe both Dirac holes and electrons on the surface, which allows us to reconstruct the surface band dispersion across the Dirac point.

description: Mentorship in the AI community is crucial to maintaining and increasing diversity, especially with respect to fostering the academic growth of underserved students. While the research process itself is important, there is not sufficient emphasis on the submission, presentation, and publication process, which is a cause for concern given the meteoric rise of predatory scientific conferences, which are based on profit only and have little to no peer review. These conferences are a direct threat to integrity in science by promoting work with little to no scientific merit. However, they also threaten diversity in the AI community by marginalizing underrepresented groups away from legitimate conferences due to convenience and targeting mechanisms like e-mail invitations. Due to the importance of conference presentation in AI research, this very specific problem must be addressed through direct mentorship. In this work, we propose PreDefense, a mentorship program that seeks to guide underrepresented students through the scientific conference and workshop process, with an emphasis on choosing legitimate venues that align with the specific work that the students are focused in and preparing students of all backgrounds for future successful, integrous AI research careers.

description: The following is true in the Solovay model. 1. If $\leq$ is a Borel partial quasi-order on a Borel set $D$ of the reals, $X$ is a ROD subset of $D$, and $\leq$ restricted to $X$ is linear, then $X$ is countably cofinal in the sense of $\leq$. 2. If in addition every countable set $Y$ of $D$ has a strict upper bound in the sense of $\leq$, then the ordering $< D ; \leq >$ has no maximal chains that are ROD sets.

description: The location of the center of rotation (COR) of joints is a key parameter in multiple applications of human motion analysis. The aim of this work was to propose a novel real-time estimator of the center of fixed joints using an inertial measurement unit (IMU). Since the distance to this center commonly varies during the joint motion due to soft tissue artifacts (STA), our approach is aimed at adapting to these small variations when the COR is fixed. Our proposal, called ArVEd, to the best of our knowledge, is the first real-time estimator of the IMU-joint center vector based on one IMU. Previous works are off-line and require a complete measurement batch to be solved and most of them are not tested on the real scenario. The algorithm is based on an Extended Kalman Filter (EKF) that provides an adaptive vector to STA motion variations at each time instant, without requiring a pre-processing stage to reduce the level of noise. ArVEd has been tested through different experiments, including synthetic and real data. The synthetic data are obtained from a simulated spherical pendulum whose COR is fixed, considering both a constant and a variable IMU-joint vector, that simulates translational IMU motions due to STA. The results prove that ArVEd is adapted to obtain a vector per sample with an accuracy of 6.8$\pm$3.9 on the synthetic data, that means an error lower than 3.5% of the simulated IMU-joint vector. Its accuracy is also tested on the real scenario estimating the COR of the hip of 5 volunteers using as reference the results from an optical system. In this case, ArVEd gets an average error of 9.5% of the real vector value. In all the experiments, ArVEd outperforms the published results of the reference algorithms.

description: The growth of ridehailing (RH) companies over the past few years has affected urban mobility in numerous ways. Despite widespread claims about the benefits of such services, limited research has been conducted on the topic. This paper assesses the willingness of Munich transportation users to pay for RH services. Realizing the difficulty of obtaining data directly from RH companies, a stated preference survey was designed. The dataset includes responses from 500 commuters. Sociodemographic attributes, current travel behavior and transportation mode preference in an 8 km trip scenario using RH service and its similar modes (auto and transit), were collected. A multinomial logit model was used to estimate the time and cost coefficients for using RH services across income groups, which was then used to estimate the value of time (VOT) for RH. The model results indicate RH services popularity among those aged 18 to 39, larger households and households with fewer autos. Higher income groups are also willing to pay more for using RH services. To examine the impact of RH services on modal split in the city of Munich, we incorporated RH as a new mode into an existing nested logit mode choice model using an incremental logit. Travel time, travel cost and VOT were used as measures for the choice commuters make when choosing between RH and its closest mode, metro. A total of 20 scenarios were evaluated at four different congestion levels and four price levels to reflect the demand in response to acceptable costs and time tradeoffs.

description: Filament eruptions and hard X-ray (HXR) source motions are commonly observed in solar flares, which provides critical information on the coronal magnetic reconnection. This Letter reports an event on 2005 January 15, in which we found an asymmetric filament eruption and a subsequent coronal mass ejection together with complicated motions of HXR sources during the GOES-class X2.6 flare. The HXR sources initially converge to the magnetic polarity inversion line (PIL), and then move in directions either parallel or perpendicular to the PIL depending on the local field configuration. We distinguish the evolution of the HXR source motion in four phases and associate each of them with distinct regions of coronal magnetic fields as reconstructed using a non-linear force-free field extrapolation. It is found that the magnetic reconnection proceeds along the PIL toward the regions where the overlying field decreases with height more rapidly. It is also found that not only the perpendicular but the parallel motion of the HXR sources correlates well with the HXR lightcurve. These results are discussed in favor of the torus instability as an important factor in the eruptive process.

description: We make use of Spitzer imaging between 4 and 16 micron and near-infrared data at 2.2 micron to investigate the nature and distribution of the mid-infrared emission in a sample of early-type galaxies in the Virgo cluster. These data allow us to conclude, with some confidence, that the emission at 16 micron in passive ETGs is stellar in origin, consistent with previous work concluding that the excess mid-infrared emission comes from the dusty envelopes around evolved AGB stars. There is little evidence for the mid-infrared emission of an unresolved central component, as might arise in the presence of a dusty torus associated with a low-luminosity AGN. We nonetheless find that the 16 micron emission is more centrally peaked than the near-infrared emission, implying a radial stellar population gradient. By comparing with independent evidence from studies at optical wavelengths, we conclude that a metallicity that falls with increasing radius is the principal driver of the observed gradient. We also plot the mid-infrared colour-magnitude diagram and combine with similar work on the Coma cluster to define the colour-magnitude relation for absolute K-band magnitudes from -26 to -19. Because a correlation between mass and age would produce a relation with a gradient in the opposite sense to that observed, we conclude that the relation reflects the fact that passive ETGs of lower mass also have a lower average metallicity. The colour-magnitude relation is thus driven by metallicity effects. In contrast to what is found in Coma, we do not find any objects with anomalously bright 16 micron emission relative to the colour-magnitude relation. Although there is little overlap in the mass ranges probed in the two clusters, this may suggest that observable ``rejuvenation'' episodes are limited to intermediate mass objects.

Five-year survival rate of bonded dental restorations In frail older adults
Creators: name: Tong, Nicholas
Publisher: name: University of British Columbia
Year: 2019

description: Objectives: Frail older adults who reside in long-term care (LTC) facilities are among the most vulnerable to dental caries due to poor oral hygiene (OH), medication-related salivary hypofunction, diets high in carbohydrates, and limited access to dental care. Providing dental restorations for LTC patients is challenging and there is a lack of studies investigating the longevity of dental restorations in this cohort. Over the years, multiple dental restorative materials have been used to restore tooth anatomy in an aesthetic manner as well as to address dental caries prevention using fluoride-based materials. This study examined the longevity of direct bonded dental restorations placed in LTC patients. Specifically, we aimed to determine if there is a difference in survival between resin composite (RC) and glass ionomer cement (GIC) direct restorations in frail older adults residing in LTC. Methods: Tooth-coloured restorations placed in LTC patients between 2007-2012, within the University of British Columbia Geriatric Dentistry Program, were followed annually up to five years or until they incurred an event (i.e. re-restoration or tooth extraction), or the patient was lost to follow-up or deceased. Restoration status was documented within the Clinical Oral Disorder in Elders (CODE) Index annual oral health assessments. Mixed-effect logistic regression was calculated to determine hazard ratios, address within-patient correlation and measure the effect size of multiple covariates. Results: A total of 3,201 dental restorations placed in 846 LTC patients were followed. This cohort of patients had a mean age of 86 years, high levels of oral disease, systemic disease and polypharmacy, and had on average 2.5 carious teeth at presentation. Over 50% of patients were wheelchair-bound and had compromised ability to perform OH. The overall 5-year survival rate was 60.3% overall and there was no statistically significant difference in survival rates between RC and GIC restorations. Conclusion: Tooth-coloured dental restorations had reasonable longevity in LTC patients and had comparable survival to restorations placed in functionally independent, community-dwelling geriatric populations. No difference between RC and GIC was found with regards to restoration longevity in this population.

description: In today's technology environment, information is abundant, dynamic, and heterogeneous in nature. Automated filtering and prioritization of information is based on the distinction between whether the information adds substantial value toward one's goal or not. Contextual multi-armed bandit has been widely used for learning to filter contents and prioritize according to user interest or relevance. Learn-to-Rank technique optimizes the relevance ranking on items, allowing the contents to be selected accordingly. We propose a novel approach to top-K rankings under the contextual multi-armed bandit framework. We model the stochastic reward function with a neural network to allow non-linear approximation to learn the relationship between rewards and contexts. We demonstrate the approach and evaluate the the performance of learning from the experiments using real world data sets in simulated scenarios. Empirical results show that this approach performs well under the complexity of a reward structure and high dimensional contextual features.

description: Multiwavelength opportunities have provided important new insights into the properties of binary/multiple 5 Msun stars. The combination of cool evolved primaries and hot secondaries in Cepheids (geriatric B stars) has yielded detailed information about the distribution of mass ratios. It has also provided a surprisingly high fraction of triple systems. Ground-based radial velocity orbits combined with satellite data from Hubble, FUSE, IUE, and Chandra can provide full information about the systems, including the masses. In particular, X-ray observations can identify low mass companions which are young enough to be physical companions. These multiwavelength observations provide important tests for star formation scenarios including diffenences between high and low mass results and differences between close and wide binaries.

A Safe Control Architecture Based on a Model Predictive Control Supervisor for Autonomous Driving

description: This paper presents a novel, safe control architecture (SCA) for controlling an important class of systems: safety-critical systems. Ensuring the safety of control decisions has always been a challenge in automatic control. The proposed SCA aims to address this challenge by using a Model Predictive Controller (MPC) that acts as a supervisor for the operating controller, in the sense that the MPC constantly checks the safety of the control inputs generated by the operating controller and intervenes if the control input is predicted to lead to a hazardous situation in the foreseeable future invariably. Then an appropriate backup scheme can be activated, e.g., a degraded control mechanism, the transfer of the system to a safe state, or a warning signal issued to a human supervisor. For a proof of concept, the proposed SCA is applied to an autonomous driving scenario, where it is illustrated and compared in different obstacle avoidance scenarios. A major challenge of the SCA lies in the mismatch between the MPC prediction model and the real system, for which possible remedies are explored.

description: Using the fact the BTZ black hole is a quotient of AdS_3 we show that classical string propagation in the BTZ background is integrable. We construct the flat connection and its monodromy matrix which generates the non-local charges. From examining the general behaviour of the eigen values of the monodromy matrix we determine the set of integral equations which constrain them. These equations imply that each classical solution is characterized by a density function in the complex plane. For classical solutions which correspond to geodesics and winding strings we solve for the eigen values of the monodromy matrix explicitly and show that geodesics correspond to zero density in the complex plane. We solve the integral equations for BMN and magnon like solutions and obtain their dispersion relation. Finally we show that the set of integral equations which constrain the eigen values of the monodromy matrix can be identified with the continuum limit of the Bethe equations of a twisted SL(2, R) spin chain at one loop.
