Running Head: THE UTILITY OF AN EFFECTIVE STUDY PROGRAM The Utility of an Effective Study Program Intervention for Improving the Study Skills of At Risk College Students: An Exploratory Study

The purpose of this exploratory study was to evaluate an Effective Study Program as an intervention strategy for increasing the basic study skills of at-risk college students at a mid size urban university that is predominantly African American, nontraditional and commuter. The evaluation was a single group pre and post test design using student scores (n=45) on the Learning and Study Strategies Inventory (Weinstein & Palmer, 2002). It was hypothesized that post-test scores would be significantly higher than pre-test scores after a 5 week Effective Study Program intervention designed to increase study skills. All posttest scores were higher than pretest scores and a series of paired sample t-tests indicated that posttest scores were on average significantly higher (p< .05) than pretest scores for all ten scales. Effect sizes ranged from small (d = .19) to large (d = .78).
Machine Learning Surrogates for Predicting Response of an Aero-Structural-Sloshing System

This study demonstrates the feasibility of developing machine learning (ML) surrogates based on Recurrent Neural Networks (RNN) for predicting the unsteady aeroelastic response of transonic pitching and plunging wing-fuel tank sloshing system by considering an approximate simplified model of an airfoil in transonic flow and sloshing loads from a partially filled fuel tank rigidly embedded inside the airfoil and undergoing a free unsteady motion. The ML surrogates are then used to predict the aeroelastic response of the coupled system. The external aerodynamic loads on the airfoil and the two-phase sloshing loads data for training the RNN are generated using open-source computational fluid dynamics (CFD) codes. The aerodynamic force and moment coefficients are predicted from the surrogate model based on its motion history. Similarly, the lateral and vertical forces and moments from fuel sloshing in the fuel tank are predicted using the surrogate model resulting from the motion of the embedded fuel tank. Comparing the free motion of the airfoil without sloshing tank to the free motion of the airfoil with a partially-filled fuel tank shows that the effects of sloshing on the aeroelastic motion of the aero-structural system. The effectiveness of the predictions from RNN are then assessed by comparing with the results from the high-fidelity coupled aero-structural-fuel tank sloshing simulations. It is demonstrated that the surrogate models can accurately and economically predict the coupled aero-structural motion.
Detection of a high-redshift molecular outflow in a primeval hyperstarburst galaxy

We report the discovery of a high-redshift, massive molecular outflow in the starburst galaxy SPT0346-52 ($z=5.656$) via the detected absorption of high-excitation water transitions (H$_2$O $4_{2,3}-4_{1,4}$ and H$_2$O $3_{3,0}-3_{2,1}$) with the Atacama Large Millimeter/submillimeter Array (ALMA). The host galaxy is one of the most powerful starburst galaxies at high redshift (star formation rate; SFR $\sim3,600$M$_\odot$year$^{-1}$), with an extremely compact ($\sim320$pc) star formation region and a star formation rate surface density ($\Sigma_{SFR}\sim5,500$M$_{\odot}~$year$^{-1}~$kpc$^{-2}$) five times higher than `maximum' (i.e. Eddington-limited) starbursts, implying a highly transient phase. The estimated outflow rate is $\sim500$M$_{\odot}$year$^{-1}$, which is much lower than the SFR, implying that in this extreme starburst the outflow capabilities saturate and the outflow is no longer capable of regulating star formation, resulting in a runaway process in which star formation will use up all available gas in less than 30Myr. Finally, while previous kinematic investigations of this source revealed possible evidence for an ongoing major merger, the coincidence of the hyper-compact starburst and high-excitation water absorption indicates that this is a single starburst galaxy surrounded by a disc.
How do atomic code uncertainties affect abundance measurements in the intracluster medium?

Accurate chemical abundance measurements of X-ray-emitting atmospheres pervading massive galaxies, galaxy groups, and clusters provide essential information on the star formation and chemical enrichment histories of these large-scale structures. Although the collisionally ionized nature of the intracluster medium (ICM) makes these abundance measurements relatively easy, the underlying spectral models can rely on different atomic codes, which brings additional uncertainties on the inferred abundances. Here we provide a simple, yet comprehensive comparison between the codes SPEXACT v3.0. 5 (cie model) and AtomDB v3.0. 9 (vapec model) in the case of moderate, charged-coupled device-like resolution spectroscopy. We show that in cool plasmas (kT ≲ 2 keV), systematic differences up to ∼20% for the Fe abundance and ∼45% for the O/Fe, Mg/Fe, Si/Fe, and S/Fe ratios may still occur. Importantly, these discrepancies are also found to be instrument-dependent, at least for the absolute Fe abundance. Future improvements in these two codes will be necessary to better address questions on ICM enrichment.
Archipelago: A Scalable Low-Latency Serverless Platform

The increased use of micro-services to build web applications has spurred the rapid growth of Function-as-a-Service (FaaS) or serverless computing platforms. While FaaS simplifies provisioning and scaling for application developers, it introduces new challenges in resource management that need to be handled by the cloud provider. Our analysis of popular serverless workloads indicates that schedulers need to handle functions that are very short-lived, have unpredictable arrival patterns, and require expensive setup of sandboxes. The challenge of running a large number of such functions in a multi-tenant cluster makes existing scheduling frameworks unsuitable. We present Archipelago, a platform that enables low latency request execution in a multi-tenant serverless setting. Archipelago views each application as a DAG of functions, and every DAG in associated with a latency deadline. Archipelago achieves its per-DAG request latency goals by: (1) partitioning a given cluster into a number of smaller worker pools, and associating each pool with a semi-global scheduler (SGS), (2) using a latency-aware scheduler within each SGS along with proactive sandbox allocation to reduce overheads, and (3) using a load balancing layer to route requests for different DAGs to the appropriate SGS, and automatically scale the number of SGSs per DAG. Our testbed results show that Archipelago meets the latency deadline for more than 99% of realistic application request workloads, and reduces tail latencies by up to 36X compared to state-of-the-art serverless platforms.
Quantum motion of a spinless particle in curved space: A viewpoint of scattering theory

In this work, we study the scattering of a spinless charged particle constrained to move on a curved surface in the presence of the Aharonov-Bohm potential. We begin with the equations of motion for the surface and transverse dynamics previously obtained in the literature (Ferrari G. and Cuoghi G., Phys. Rev. Lett., 100 (2008) 230403) and describe the surface with non-trivial curvature in terms of linear defects such as dislocations and disclinations. Expressions for the modified phase shift, S-matrix and scattering amplitude are determined by applying a suitable boundary condition at the origin, which comes from the self-adjoint extension theory. We also discuss the presence of a bound state obtained from the pole of the S-matrix. Finally, we claim that the bound state, the additional scattering and the dependence of the scattering amplitude with energy are solely due to the curvature effects.
WildMix Dataset and Spectro-Temporal Transformer Model for Monoaural Audio Source Separation

Monoaural audio source separation is a challenging research area in machine learning. In this area, a mixture containing multiple audio sources is given, and a model is expected to disentangle the mixture into isolated atomic sources. In this paper, we first introduce a challenging new dataset for monoaural source separation called WildMix. WildMix is designed with the goal of extending the boundaries of source separation beyond what previous datasets in this area would allow. It contains diverse in-the-wild recordings from 25 different sound classes, combined with each other using arbitrary composition policies. Source separation often requires modeling long-range dependencies in both temporal and spectral domains. To this end, we introduce a novel trasnformer-based model called Spectro-Temporal Transformer (STT). STT utilizes a specialized encoder, called Spectro-Temporal Encoder (STE). STE highlights temporal and spectral components of sources within a mixture, using a self-attention mechanism. It subsequently disentangles them in a hierarchical manner. In our experiments, STT swiftly outperforms various previous baselines for monoaural source separation on the challenging WildMix dataset.
Verbal Programming of Robot Behavior

Home robots may come with many sophisticated built-in abilities, however there will always be a degree of customization needed for each user and environment. Ideally this should be accomplished through one-shot learning, as collecting the large number of examples needed for statistical inference is tedious. A particularly appealing approach is to simply explain to the robot, via speech, what it should be doing. In this paper we describe the ALIA cognitive architecture that is able to effectively incorporate user-supplied advice and prohibitions in this manner. The functioning of the implemented system on a small robot is illustrated by an associated video.
Order Ma ers at Fanatics

A unique challenge for e-commerce recommendation is that customers are often interested in products that are more advanced than their already purchased products, but not reversed. The few existing recommender systems modeling unidirectional sequence output a limited number of categories or continuous variables. To model the ordered sequence, we design the first recommendation system that both embed purchased items with Word2Vec, and model the sequence with stateless LSTM RNN. The click-through rate of this recommender system in production outperforms its solely Word2Vec based predecessor. Developed in 2017, it was perhaps the first published real-world application that makes distributed predictions of a single machine trained Keras model on Spark slave nodes at a scale of more than 0.4 million columns per row.
Prevalence of tinnitus complaints and probable association with hearing loss, diabetes mellitus and hypertension in elderly.

PURPOSE To assess the prevalence of tinnitus and possible association with hearing loss, diabetes mellitus and hypertension in elderly. METHODS Cross-sectional study with individuals older than 60 years who underwent audiological evaluation (pure tone audiometry and history) and answered a comorbidity questionnaire. We evaluated 519 subjects of both genders with a median age of 69 years. Individuals who did not participate in the audiometric test were excluded, then totaling 498 subjects. We applied the appropriate statistical tests to analyze the tinnitus and associated factors. RESULTS The prevalence of 42.77% of tinnitus was found, being 58.68% bilateral tinnitus and 41.31% unilateral tinnitus. There was a difference between tinnitus and hearing loss, but there was no difference between tinnitus and hypertension and between tinnitus and diabetes mellitus alone. CONCLUSION The prevalence of tinnitus is significant in the elderly. There are differences between tinnitus and hearing loss, with association between the side affected by tinnitus and the side of hearing loss. Only the association of comorbidity of diabetes mellitus and hypertension is an independent risk factor for tinnitus.
PREVALENCE OF CYTOMEGALOVIRUS INFECTION IN PATIENTS WITH ULCERATIVE COLITIS BY USING PCR TECHNIQUE

Background: Ulcerative colitis is one type of inflammatory bowel disease. Objectives: The aim of this study was to investigate the prevalence of cytomegalovirus in patients with ulcerative colitis in comparison with healthy subjects by using PCR technique. Patients and Methods: In this analytical case-control study, 5 patients with ulcerative colitis and 30 patients without malignancy as controls were selected. Biopsy specimens were frozen under sterile conditions at -20oC. After DNA extraction, analysis of polymerase chain reaction (PCR) to detect CMV DNA in tissue samples was performed. Statistical analysis was performed with χ2 test. Results: CMV DNA was found in 80% of ulcerative colitis samples (4 of 5) and 30% of the non-malignant control group (9 of 30). Statistical analysis showed significant association between the prevalence of CMV and incidence ulcerative colitis in comparison with the control group (P = 0.03). Conclusions: The results of the present study has shown ulcerative colitis patients have a predisposition to CMV infection as compared to healthy individuals, but the etiologic link between ulcerative colitis and CMV infection needs to be studied.

Five hours after aspirin administration, the first group received placebo (distilled water); the second, third and forth group received 2gm/kg, 3gm/kg and 4gm/kg of banana powder (3 times in a day) respectively for 2 days. On 5 th day, the animals were sacrificed and stomach was removed for examination. Orally administered banana powder in the dose of 3gm/kg and 4gm/kg caused a statistically significant decrease in aspirin induced ulcers in rats. It can be concluded from these results that vegetable plantain banana has ulcer healing and mucosal protective actions.
Strategies for Mapping Concepts in Gastrointestinal Endoscopy Reports to the UMLS Metathesaurus

Automatic access to information in clinical free text can provide support for medical decision support, outcome research, continuous quality improvement, and information retrieval. We discuss three strategies to improve results when using MetaMap [1] to map strings in gastrointestinal endoscopy (GIE) reports to concepts in the Unified Medical Language System (UMLS) ® Metathesaurus. Due to word sense ambiguity, synonymy, and context-specific meaning, using MetaMap without modification produces limited results in this domain. For example, esophagus is incorrectly mapped to “Procedures of the esophagus. ”
FACTORS INFLUENCING THE RECRUITMENT AND RETENTION OF UNDERGRADUATES AS REPORTED BY AFRICAN AMERICAN GRADUATES OF TEXAS A&M UNIVERSITY BETWEEN

Factors Influencing the Recruitment and Retention of Undergraduates as Reported by African American Graduates of Texas A&M University Between May 1998 and December 2003. (August 2005) John Gabriel Harnsberry, B.S., Huston-Tillotson University; M.Ed., Texas A&M University Chair of Advisory Committee: Dr. Stephen L. Stark The purpose of this study was to examine the influential effects various factors had on the recruitment and the retention of African American undergraduates at Texas A&M University, as perceived by those African Americans who had successfully completed their plans of study and received baccalaureate degrees between May 1998 and December 2003. Data were acquired through e-mail surveys in which three massive e-mailings were broadcast from the collected files of The Association of Former Students of Texas A&M. In this survey, the questionnaire contained closed-ended questions with five-part Likert-type responses. Additionally, the African American alumni were provided the opportunity to recommend additional practices for future recruitment and retention of African American undergraduates at A&M. An extensive review of the literature that supports this record of study regarding recruitment and retention of African American undergraduate students was made, and in the review, family involvement in education and home/school/campus characteristics
Efeito do exercício físico na percepção de satisfação de vida e função imunológica em pacientes infectados pelo HIV: Ensaio clínico não randomizado

BACKGROUND: There is a lack of research about the relationship between exercise and the psychological well-being of HIV-infected (Human Immunodeficiency Virus) patients. OBJECTIVE: The objective of this study was to investigate the influence of a physical training program on life satisfaction and on the immunological function in HIV-patients. METHODS: A total of 29 HIV-seropositive patients [age: 45±2 yrs; Body Mass Index (BMI): 22.8±1.0 kg/m2 ; TCD4: 20.5±2.0%] were allocated to the control (CG, n=10) and to the experimental groups (EG, n=19). The EG participated in an exercise program combining aerobic, strength, and flexibility exercises for a period of 12 weeks [3 times/week of 30 min of aerobic exercise (workload corresponding to 150 bpm-PWC150); 50 min of strength exercises (3 sets of 12 repetitions in 5 exercises at 60-80% 12 RM); and 10 min of flexibility exercises (2 sets of 30 seconds at maximal range of motion of 8 exercises)]. The immunological function was assessed by flow citometry [absolute and relative TCD4 cells counting] and the life satisfaction was assessed by the Life Satisfaction Index (LSI). RESULTS: The analysis of variance (ANOVA) showed no significant differences for relative and absolute CD4 T counts for both groups, however, a slight enhancement trend in the EG [16%, p=0.19] was observed. There was a significant improvement of LSI [approximately 15%; P<0.05] in EG, but not for CG. CONCLUSION: A physical activity program of moderate intensity improved life satisfaction perception in HIV-infected patients with no immunological function impairment.
EFFECT OF HYDROALCOHOLIC EXTRACTS OF SIDA CORDIFOLIA L. LEAVES ON LIPID PROFILE IN RATS

Summary Sida cordifolia L (Malvaceae) is important medicinal plant of Ayurvedic system of medicine and used as home remedy as cardioprotective agent without any scientific background. In this investigation an attempt was made to study the effect of hydroalcoholic extract of Sida cordifolia L (HESC) on serum lipid profile, which is closely associated with many cardiovascular diseases. Albino rats were administered HESC (100 mg/kg and HESC 500 mg/kg) once daily orally for 30 days. Accordingly, serum total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) were among the parameters investigated. We also evaluated the activities of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels as a measure of hepatic cell damages. It was found in our study that the administration of both doses of HESC to animals fed with high fat diet (HFD) lowered their serum TC, TG and LDL-C significantly, while raised the serum HDL-C. Treatment with HESC reduced serum ALT and AST levels compared to HFD groups. Further, it was also observed that the high dose of HESC significantly decreases serum TC, TG and LDL-C and increases HDL-C in animals fed with normal fat diet (NFD). Based on these data, it is concluded that the chronic administration of HESC in high dose up to 500 mg/kg has definite cardioprotective potential and these results constitute a valid scientific basis for consuming Sida cordifolia L for medicinal application.
Distribuição da força plantar e oscilação do centro de pressão em relação ao peso e posicionamento do material escolar

OBJECTIVE: The influence of the weight and positioning of school supplies and books in backpacks, on plantar force distribution (PFD) and pressure center location, was investigated among students. METHODS: Thirty volunteers of both genders participated in the study. Their mean age was 10.76 (± 1.35) years and none of them had postural abnormalities. Baropodometric data were collected using a computerized baropodometric system (Matscan Research, Tekscanâ, 5.72): without load (control) and with loads of 5, 10 and 15% of body weight in a backpack, positioned on the back, on the chest and on the right and left shoulders. RESULTS: The PFD without load was greater on the left heel than on the right heel (p< 0.05). With a load of 10% on the left shoulder, the PFD was greater on the right and smaller on the left foot, in comparison with the control (p< 0.05). With a load of 5% on the back, the PFD was smaller on the right midfoot (RMF) and left forefoot (lff); with 10%, it was smaller on the RMF and left midfoot (LMF) and greater on the right toes (RT); with 15%, it was smaller on the RMF and greater on the RT (p< 0.05). The plantar force was greater on the RT with loads of 10% and 15% than it was with loads of 5% (p< 0.05). With loads of 15% on the back and on the chest, the pressure center displacement was greater than with a load of 5% (p< 0.05). The PFD was not influenced by the different loads and backpack positions. CONCLUSIONS: Taking into consideration the increased pressure center displacement with a load of 15%, it is recommended that school backpack loads should not exceed 10% of body mass. Investigations on posture adaptations to different loads and backpack positions are suggested, in order to detect possible abnormalities and propose preventive actions.
Internal resonances and relaxation memory kernels in composites

In heterogeneous composite materials, the behaviour of the medium on larger scales is determined by the microgeometry and properties of the constituents on finer scales. To model the influence of the microlevel processes in composite materials, they are described as materials with memory in which the constitutive relations between stress and strain are given as time-domain convolutions with some relaxation kernel. The paper reveals the relationship between the viscoelastic relaxation kernel and the spectral measure in the Stieltjes integral representation of the effective properties of composites. This spectral measure contains all information about the microgeometry of the material, thus providing a link between the relaxation kernel and the microstructure of the composite. We show that the internal resonances of the microstructure determine the characteristic relaxation times of the fading memory kernel and can be used to introduce a set of internal variables that captures dissipation at the microscale. This article is part of the theme issue ‘Modelling of dynamic phenomena and localization in structured media (part 2)’.
