Diabetes Prevention Program Translation in the Veterans Health Administration.
Venue: American journal of preventive medicine
Year: 2017

This clinical demonstration trial compared the effectiveness of the Veterans Affairs Diabetes Prevention Program (VA DPP) with an evidence based usual care weight management program (MOVE!(r) in the Veterans Health Administration health system.  Prospective, pragmatic, non randomized comparative effectiveness study of two behavioral weight management interventions.  Obese/overweight Veterans with prediabetes were recruited from three geographically diverse VA sites between 2012 and 2014.  DPP included 22 group based intensive lifestyle change sessions.  Weight change at 6 and 12 months, hemoglobin A1c (HbA1c) at 12 months, and VA health expenditure changes at 15 months were assessed using VA electronic health record and claims data. Between and within group comparisons for weight and HbA1c were done using linear mixed effects models controlling for age, gender, race/ethnicity, baseline outcome values, and site. Analyses were conducted in 2015 2016.  A total of 387 participants enrolled (273 VA DPP, 114 MOVE! More VA DPP participants completed at least one (73.3% VA DPP vs 57.5% MOVE! p=0.002) four (57.5% VA DPP vs 42.5% MOVE! p=0.007) and eight or more sessions (42.5% VA DPP vs 31% MOVE! p=0.035) Weight loss from baseline was significant at both 6 (p<0.001) and 12 months (p<0.001) for VA DPP participants, but only significant at 6 months for MOVE! participants (p=0.004) Between groups, there were significant differences in 6 month weight loss 4.1 kg VA DPP vs 1.9 kg MOVE! p<0.001) but not 12 month weight loss 3.4 kg VA DPP vs 2.0 kg MOVE! p=0.16) There were no significant differences in HbA1c change or outpatient, inpatient, and total VA expenditures.  DPP participants had higher participation rates and weight loss at 6 months, but similar weight, HbA1c, and health expenditures at 12 months compared to MOVE! PARTICIPANTS Features of VA DPP may help enhance the capability of MOVE! to reach a larger proportion of the served population and promote individual level weight maintenance.
DiverseDepth: Affine invariant Depth Prediction Using Diverse Data
Venue: ArXiv
Year: 2020

We present a method for depth estimation with monocular images, which can predict high quality depth on diverse scenes up to an affine transformation, thus preserving accurate shapes of a scene. Previous methods that predict metric depth often work well only for a specific scene. In contrast, learning relative depth (information of being closer or further) can enjoy better generalization, with the price of failing to recover the accurate geometric shape of the scene. In this work, we propose a dataset and methods to tackle this dilemma, aiming to predict accurate depth up to an affine transformation with good generalization to diverse scenes. First we construct a large scale and diverse dataset, termed Diverse Scene Depth dataset (DiverseDepth) which has a broad range of scenes and foreground contents. Compared with previous learning objectives, i.e. learning metric depth or relative depth, we propose to learn the affine invariant depth using our diverse dataset to ensure both generalization and high quality geometric shapes of scenes. Furthermore, in order to train the model on the complex dataset effectively, we propose a multi curriculum learning method. Experiments show that our method outperforms previous methods on 8 datasets by a large margin with the zero shot test setting, demonstrating the excellent generalization capacity of the learned model to diverse scenes. The reconstructed point clouds with the predicted depth show that our method can recover high quality 3D shapes. Code and dataset are available at: this https URL
Hair and beauty choices of African American women during the Civil Rights Movement, 1960 1974
Year: 2016

This research examined the Civil Rights Movement, specifically focusing on hair and beauty choices of African American women who were emerging adults (ages 18 25) between the years 1960 1974, which bridges both the classical period of the Civil Rights Movement and that of Black Power politics (Wilson, 2013) The specific time period corresponds with the adoption of African American hairstyles that were more Afrocentric, following the social climate of Black Pride (Walker, 2007) To achieve understanding of African American women's perspectives, seven participants were interviewed using Seidman's (2013) protocol for which a three part, in depth interview series was conducted. The successive interviews concentrated on the themes of: 1) hair history throughout their lives, 2) details of experiences during the Civil Rights Movement years 1960 74, and 3) creating reflections on the meaning of hairstyle choices in the participant's life. This dissertation followed a non traditional format that allowed for the completion of two scholarly articles related to African American women's hair. Article one: Ages and stages: African American women and their lives through their hair, examines participants' presentations of self. Communication of meaning and values associated with dress were negotiated between the participants and others, which resulted in their choices of presentation. Goffman's (1959) discussion of the presentation of self was used to explain how marginalized groups strive to act appropriately or ideally to dominant standards and power groups. Participants described how they chose their hairstyles and dress for varying audiences and settings. Their presentation of self was highly influenced by the intersectional subject positions held by the participants, reflecting larger hegemonic norms in U.S. society.
A new semantic similarity approach for improving the results of an Arabic search engine
Venue: ANT/EDI40
Year: 2019

Determining semantic similarity between documents is crucial to many tasks such as plagiarism detection, automatic technical survey and semantic search. In this paper, we have mainly focused on detecting the semantic similarity between documents in large documents collection and queries based on an Arabic search engine, we investigated MapReduce as a specific framework for managing distributed processing in dataset pattern and semantic similarity measures of documents. Then we study the state of the art of different approaches for computing the similarity of documents. We propose an approach based on parallel algorithm of semantic similarity measures using MapReduce and WordNet after translation phase to detect the relevant documents in the face of the Arabic query. The numerical results obtained and presented showed the efficiency and the performance of the technique adopted.
Optimal Replacement of Soybean Meal with Fermented Palm Kernel Meal as Protein Source in a Fish Meal Soybean Meal Based Diet of Sex Reversed Red Tilapia (Oreochromis niloticus x O. mossambicus)
Venue: Animals an open access journal from MDPI
Year: 2021

Simple Summary Replacement effects of soybean meal (SBM) with fermented palm kernel meal (FPKM) as a protein source was investigated in sex reversed red tilapia. The two month old fish were fed fish meal SBM based diets with replacement by FPKM at 25% (25FPKM) 50% (50FPKM) 75% (75FPKM) and 100% (100FPKM) for 12 weeks, while an FPKM free diet (0FPKM) was used as a control. Based on growth performance, feed utilization, digestive enzyme activities, flesh quality, carcass composition, hematological parameters and liver histoarchitecture, the 50% replacement level of SBM by FPKM support this alternative. Findings from the current study support the use of FPKM in aquafeed production, providing a low cost diet for tilapia farming.  The solid state fermentation by effective microorganisms (containing photosynthetic bacteria, lactic acid bacteria, nitrogen fixing bacteria, yeast and Bacillus sp. improved the nutritive values of palm kernel meal (PKM) Increased crude protein (20.79% nitrogen free extract (40.07% and gross energy (19.58% were observed in fermented PKM (FPKM) relative to raw PKM while crude lipid (15.65% crude fiber (36.45% and ash (29.54% were decreased. Replacement of soybean meal (SBM) with FPKM as a protein source was investigated for its effects in sex reversed red tilapia (Oreochromis niloticus x O. mossambicus) The two month old fish (14.85 0.28 g initial weight) were fed fish meal SBM based diets with replacement by FPKM at 25% (25FPKM) 50% (50FPKM) 75% (75FPKM) and 100% (100FPKM) while an FPKM free diet (0FPKM) was used as a control. The five treatments, comprising triplicate cement ponds and forty fish each, were conducted in a recirculating system over 12 weeks. At the end of the feeding trial, fish fed the 50FPKM diet were superior in growth performance, while the feed utilization parameters were similar across all five treatments. Physiological adaptation of the protein digesting (pepsin and trypsin) and lipid digesting (lipase) enzymes was detected at all protein replacement levels (except for 25FPKM) as well as of the enzyme for cellulose digestion (cellulase) but not of the carbohydrate digesting enzymes (amylase) Protein synthesis capacity in flesh was improved in fish fed the 50FPKM diet, while the quality of the main flesh proteins, actin and myosin, showed no significant differences across the five treatments. No differences in carcass composition and no negative effects on hematological parameters or liver histoarchitecture at the 50% replacement level of SBM by FPKM also support this alternative. Findings from the current study indicate the low cost FPKM containing diet for tilapia in comparison with control diet.

Earth's Future Knowing the unknowns
Year: 2013

The Earth's atmosphere is not the only source of radiative forcing and anthropogenic climate change. As surely as people and civilizations have carbon footprints, they have albedo footprints as well. By altering the reflectivity of roughly half the land surface of the Earth in the past, mankind has made inadvertent geoengineering a part of the landscape of history. This worldwide alteration of reflectivity raises questions about the future of climate change, for albedo is a first order determinant of the Earth's radiative equilibrium. As surfaces absorb roughly 100 times more solar energy than the CO2 in the atmosphere, future anthropogenic changes in both land and water albedo may figure significantly in climate policy outcomes. At the turn of the 20th century, scientific controversy raged over the varying color of the planet Mars. Although a pleasure to look at, Victorian telescopes were of little use in taking pictures, delivering thumb nail images so dim that astronomers were reduced to sketching maps that differed so greatly that the red planet's fixed geography amounted to little more than two bright polar caps that came and went with the passing of the seasons. Yet in retrospect, 19th century Mars gazers were better off than the 20th century geographers at least they could see what they were arguing about  Although Percival Lowell's "canals" remained pho tographically elusive, they could easily gage how much sunlight Mars reflected, its "albedo," by comparing its darker regions with its snow white poles.

Clinical Evidence for Improved Outcomes with Histamine Antagonists and Aspirin in 22,560 COVID 19 Patients
Venue: medRxiv
Year: 2021

COVID 19 has spurred much interest in the therapeutic potential of repurposed drugs. A family of acid reducing drugs, known as histamine H2 receptor antagonists (H2RA) competitively bind the H2R and block its stimulation by histamine; examples of such drugs are famotidine (e.g. Pepcid) and ranitidine (e.g. Zantac) A dense web of functionalities between histamine and H2RAs, on the one hand, and downstream cellular pathways, on the other hand, links disparate physiological pathways in gastrointestinal contexts (e.g. acid reduction) to the dysregulated inflammatory cascades (cytokine storm) underlying the pathophysiology of COVID 19. Is famotidine beneficial in treating COVID 19? This question remains unresolved, though not for lack of effort: over 10 studies have examined the potential therapeutic value of famotidine in COVID 19, but have found conflicting results (pro famotidine, anti famotidine, and neutral) Given the contradictory reports, we have undertaken the new analysis reported herein. Notably, studies published thus far rest upon substantially smaller datasets than drawn upon in the pre sent work. We analyzed a cohort of 22,560 COVID 19 patients taking H1/H2 receptor antagonists, focusing on 1,379 severe cases requiring respiratory support. We analyzed outcomes for treatment with the H1RAs loratadine (e.g. Claritin) and cetirizine (e.g. Zyrtec) the H2RA famotidine, aspirin, and a famotidine aspirin combination. For cases that reached the point of respiratory support, we found a significantly reduced fatality risk for famotidine treatment. We did not detect a benefit from dual histamine receptor blockade (concurrently targeting H1 and H2 receptors) Notably, famotidine combined with aspirin did exhibit a significant synergistic survival benefit (odds ratio of 0.55) The relative risk for death decreased by 32.5% an immense benefit, given the more than 2.6 million COVID 19 related deaths thus far. We found lower levels of serum markers for severe disease (e.g. C reactive protein) in famotidine users, consistent with prior findings by others and with a role for famotidine in attenuating cytokine release. The large, international, multi center retrospective study reported here, sampling over 250,000 COVID 19 cases, hopefully helps clarify the possible value of clinically approved histamine antagonists such as famotidine. Given these findings, alongside the cost effectiveness and mild side effects of popular drugs like famotidine and aspirin, we suggest that further prospective clinical trials, perhaps utilizing the aspirin combination reported here, are advisable.
Types of ICT applications used and the skills' level of nursing students in higher education: A cross sectional survey

Constraints on the mineralization processes of the Makeng iron deposit, eastern China: Fluid inclusion, H O isotope and magnetite trace element analysis
Year: 2017

The Makeng iron deposit is located in the Yong'an Meizhou depression belt in Fujian Province, eastern China. Both skarn alteration and iron mineralization are mainly hosted within middle Carboniferous lower Permian limestone. Five paragenetic stages of skarn formation and ore deposition have been recognized: Stage 1, early skarn (andradite grossular assemblage) Stage 2, magnetite mineralization (diopside magnetite assemblage) Stage 3, late skarn (amphibole chlorite epidote johannsenite hedenbergite magnetite assemblage) Stage 4, sulfide mineralization (quartz calcite fluorite chlorite pyrite galena sphalerite assemblage) and Stage 5, carbonate (quartz calcite assemblage) Fluid inclusion studies were carried out on inclusions in diopside from Stage 2 and in quartz, calcite, and fluorite from Stage 4. Halite bearing (Type 1) and coexisting two phase vapor rich aqueous (Type 3) inclusions in the magnetite stage display homogenization temperatures of 448 564 degC and 501 594 degC, respectively. Salinities range from 26.5 to 48.4 and 2.4 to 6.9 wt% NaCl equivalent, respectively. Two phase liquid rich aqueous (Type 2b) inclusions in the sulfide stage yield homogenization temperatures and salinities of 182 343 degC and 1.9 20.1 wt% NaCl equivalent. These fluid inclusion data indicate that fluid boiling occurred during the magnetite stage and that fluid mixing took place during the sulfide stage. The former triggered the precipitation of magnetite, and the latter resulted in the deposition of Pb, Zn, and Fe sulfides. The fluids related to magnetite mineralization have d18Ofluid VSMOW of 6.7 9.6%0 and dD of 96 to 128%0, which are interpreted to indicate residual magmatic water from magma degassing. In contrast, the fluids related to the sulfide mineralization show d18Ofluid VSMOW of 0.85 to 1.04%0 and dD of 110 to 124%0, indicating that they were generated by the mixing of magmatic water with meteoric water. Magnetite grains from Stage 2 exhibit oscillatory zoning with compositional variations in major elements (e.g. SiO2, Al2O3, CaO, MgO, and MnO) from core to rim, which is interpreted as a self organizing process rather than a dissolution reprecipitation process. Magnetite from Stage 3 replaces or crosscuts early magnetite, suggesting that later hydrothermal fluid overprinted and caused dissolution and reprecipitation of Stage 2 magnetite. Trace element data (e.g. Ti, V, Ca, Al, and Mn) of magnetite from Stages 2 and 3 indicate a typical skarn origin.
Demographic variation in how the social brain processes news messages
Venue: Politics Life Sciences
Year: 2016

A high capacity for visual perception distinguishes Homo sapiens from other primates. This human ability to detect social cues and retain visual records of social networks has been tested mostly with static facial images in laboratory settings. However, media consumption has become closely entangled with the way social life is navigated. Therefore, the study reported here tested demographic differences (gender and education) in visual information processing of social and nonsocial objects featured in audiovisual news content. Women recognized (accuracy) and recalled (salience) social images better than men. On the other hand, men were more skilled at recognizing, but not recalling, nonsocial images. Participants with lower educational levels recognized and recalled fewer images than individuals with higher educational levels. Interactions between demographic variables and time suggest that memory records for social images are more stable than those for nonsocial images. Memory may have survival relevant importance, serving navigational functions that vary across environmental demands, resulting in differences across demographic groups.
An Adaptive Median Filter Based on Sampling Rate for R Peak Detection and Major Arrhythmia Analysis
Venue: Sensors
Year: 2020

With the advancement of the Internet of Medical Things technology, many vital sign sensing devices are being developed. Among the diverse healthcare devices, portable electrocardiogram (ECG) measuring devices are being developed most actively with the recent development of sensor technology. These ECG measuring devices use different sampling rates according to the hardware conditions, which is the first variable to consider in the development of ECG analysis technology. Herein, we propose an R point detection method using an adaptive median filter based on the sampling rate and analyze major arrhythmias using the signal characteristics. First, the sliding window and median filter size are determined according to the set sampling rate, and a wider median filter is applied to the QRS section with high variance within the sliding window. Then, the R point is detected by subtracting the filtered signal from the original signal. Methods for detecting major arrhythmias using the detected R point are proposed. Different types of ECG signals were used for a simulation, including ECG signals from the MIT BIH arrhythmia database and MIT BIH atrial fibrillation database, signals generated by a simulator, and actual measured signals with different sampling rates. The experimental results indicated the effectiveness of the proposed R point detection method and arrhythmia analysis technique.
An Experimental and Numerical Study on the Aerothermal Characteristics of a Ribbed Transonic Squealer Tip Turbine Blade With Purge Flow
Year: 2015

Detailed heat transfer coefficient (HTC) and film cooling effectiveness (Eta) distribution on a squealer tipped first stage rotor blade were measured using an infrared (IR) technique. The blade tip design, obtained from a Solar Turbines Inc. gas turbine, consisted of double purge hole exits and four ribs within the squealer cavity, with a bleeder exit port on the pressure side close to the trailing edge. The tests were carried out in a transient linear transonic wind tunnel facility under land based engine representative Mach/Reynolds number. Measurements were taken at an inlet turbulent intensity of Tu 12% with exit Mach numbers of 0.85 (Reexit=9.75x105) and 1.0 (Reexit 1.15x106) with the Reynolds number based on the blade axial chord and the cascade exit velocity. The tip clearance was fixed at 1% (based on engine blade span) with a purge flow blowing ratio BR 1.0. At each test condition, an accompanying numerical study was performed using Reynolds Averaged Navier Stokes (RANS) equations solver ANSYS Fluent to further understand the tip flow characteristics. The results showed that the tip purge flow has a blocking effect on the leakage flow path. Furthermore, the ribs significantly altered the flow (and consequently heat transfer) characteristics within the squealer tip cavity resulting in a significant reduction in film cooling effectiveness. This was attributed to increased coolant leakage flow mixing due to increased recirculation within the squealer cavity. Overall, the peak heat transfer coefficient on the cavity floor increased with exit Mach/Reynolds number.(c) 2015 ASME
