Authors: Ouyang Yi , Guo Bin , Guo Tong , Cao Longbing , Yu Zhiwen
Published: December 2018

In recent years, with the rapid development of mobile app ecosystem, the number and categories of mobile apps have grown tremendously. However, the global prevalence of mobile apps also leads to fierce competition. As a result, many apps will disappear. To thrive in this competitive app market, it is vital for app developers to understand the popularity evolution of their mobile apps, and inform strategic decision-making for better mobile app development. Therefore, it is significant and necessary to model and forecast the future popularity evolution of mobile apps. The popularity evolution of mobile apps is usually a long-term process, affected by various complex factors. However, existing works lack the capabilities to model such complex factors. To better understand the popularity evolution, in this paper, we aim to forecast the popularity evolution of mobile apps by incorporating complex factors, i.e., exogenous stimulis and endogenous excitations. Specifically, we propose a model based on the Multivariate Hawkes Process (MHP), which is an exogenous stimulis-driven self-exciting point process, to model the exogenous stimulis and endogenous excitations simultaneously. Extensive experimental studies on a real-world dataset from app store demonstrate that MHP outperforms the state-of-the-art methods regarding popularity evolution forecasting.

We present the use of in-car virtual reality (VR) as a way to create calm, mindful experiences for passengers and, someday, autonomous vehicle occupants. Specifically, we describe a series of studies aimed at exploring appropriate VR content, understanding the influence of car movement, and determining the length and other parameters of the simulation to avoid physical discomfort. Overall, our quantitative and qualitative insights suggest calm VR applications are well suited to an automotive context. Testing combinations of VR content designed to provide the participant with a static or dynamic experience versus stationary and moving vehicle modes, we find that a simulated experience of diving in the ocean while in a moving car elicited significantly lower levels of autonomic arousal as compared with a static VR plus stationary car condition. No significant motion sickness effects were subjectively reported by participants nor observable in the data, though a crossover interaction effect reveals how incongruence between the movement of the car and movement in VR could affect nausea. We conclude with recommendations for the design of calming and mindful VR experiences in moving vehicles.

Published: December 2018

Worn sensors are popular for automatically tracking exercises. However, a wearable is usually attached to one part of the body, tracks only that location, and thus is inadequate for capturing a wide range of exercises, especially when other limbs are involved. Cameras, on the other hand, can fully track a user's body, but suffer from noise and occlusion. We present GymCam, a camera-based system for automatically detecting, recognizing and tracking multiple people and exercises simultaneously in unconstrained environments without any user intervention. We collected data in a varsity gym, correctly segmenting exercises from other activities with an accuracy of 84.6%, recognizing the type of exercise at 93.6% accuracy, and counting the number of repetitions to within ± 1.7 on average. GymCam advances the field of real-time exercise tracking by filling some crucial gaps, such as tracking whole body motion, handling occlusion, and enabling single-point sensing for a multitude of users.
DeepType

Published: December 2018

Mobile users spend an extensive amount of time on typing. A more efficient text input instrument brings a significant enhancement of user experience. Deep learning techniques have been recently applied to suggesting the next words of input, but to achieve more accurate predictions, these models should be customized for individual users. Personalization is often at the expense of privacy concerns. Existing solutions require users to upload the historical logs of their input text to the cloud so that a deep learning predictor can be trained. In this work, we propose a novel approach, called DeepType, to personalize text input with better privacy. The basic idea is intuitive: training deep learning predictors on the device instead of on the cloud, so that the model makes personalized and private data never leaves the device to externals. With DeepType, a global model is first trained on the cloud using massive public corpora, and our personalization is done by incrementally customizing the global model with data on individual devices. We further propose a set of techniques that effectively reduce the computation cost of training deep learning models on mobile devices at the cost of negligible accuracy loss. Experiments using real-world text input from millions of users demonstrate that DeepType significantly improves the input efficiency for individual users, and its incurred computation and energy costs are within the performance and battery restrictions of typical COTS mobile devices.
Exploring Tangible Interactions with Radar Sensing
Authors: Yeo Hui-Shyong , Minami Ryosuke , Rodriguez Kirill , Shaker George , Quigley Aaron
Published: December 2018

Research has explored miniature radar as a promising sensing technique for the recognition of gestures, objects, users' presence and activity. However, within Human-Computer Interaction (HCI), its use remains underexplored, in particular in Tangible User Interface (TUI). In this paper, we explore two research questions with radar as a platform for sensing tangible interaction with the counting, ordering, identification of objects and tracking the orientation, movement and distance of these objects. We detail the design space and practical use-cases for such interaction which allows us to identify a series of design patterns, beyond static interaction, which are continuous and dynamic. With a focus on planar objects, we report on a series of studies which demonstrate the suitability of this approach. This exploration is grounded in both a characterization of the radar sensing and our rigorous experiments which show that such sensing is accurate with minimal training. With these techniques, we envision both realistic and future applications and scenarios. The motivation for what we refer to as Solinteraction, is to demonstrate the potential for radar-based interaction with objects in HCI and TUI.
Nutritional and Pharmacological Effects on Oxidative Stress in Soft Tissue and Bone Remodeling
Authors: Savasky Benjamin M. , Mascotti David P. , Patel Naren , Rodriguez-Collazo Edgardo
Published: December 2018

Oxidative damage is the causal link to a multitude of pathologies, such as diabetes, arthritis, neuropathy, heart disease, and asthma. These conditions affect hundreds of millions of people nationwide, and billions worldwide. Even in otherwise healthy individuals, oxidative stress is a natural byproduct of metabolism that is augmented in “healthy” activities such as athletics. In many disease states, the pharmacological agents used to treat these conditions can induce oxidative damage and vitamin depletion. It is underappreciated by many that many of the most common medications prescribed result in oxidative stress. Therefore, physicians need to carefully scrutinize which medications their patients are on before surgery and treatment and during the recovery stage to obtain optimal healing results. We provide a review of the current literature of how oxidative damage and inflammation are linked to bone damage, Charcot neuroarthropathy, delayed wound healing, diabetic complications, and delayed flap consolidation. Where available, antioxidant intervention literature is offered to offset these conditions.
Models of Anisotropic Self-Gravitating Source in Einstein-Gauss-Bonnet Gravity
Authors: Abbas G. , Tahir M.
Published: December 2018

In this paper, we have studied gravitational collapse and expansion of nonstatic anisotropic fluid in 5D Einstein-Gauss-Bonnet gravity. For this purpose, the field equations have been modeled and evaluated for the given source and geometry. The two metric functions have been expressed in terms of parametric form of third metric function. We have examined the range of parameter β (appearing in the form of metric functions) for which Θ, the expansion scalar, becoming positive/negative leads to expansion/collapse of the source. The trapped surface condition has been explored by using definition of Misner-Sharp mass and auxiliary solutions. The auxiliary solutions of the field equations involve a single function that generates two types of anisotropic solutions. Each solution can be represented in term of arbitrary function of time; this function has been chosen arbitrarily to fit the different astrophysical time profiles. The existing solutions forecast gravitational expansion and collapse depending on the choice of initial data. In this case, wall to wall collapse of spherical source has been investigated. The dynamics of the spherical source have been observed graphically with the effects of Gauss-Bonnet coupling term α in the case of collapse and expansion. The energy conditions are satisfied for the specific values of parameters in both solutions; this implies that the solutions are physically acceptable.
Optimization of FCAW Parameters for Ferrite Content in 2205 DSS Welds Based on the Taguchi Design Method
Authors: Li Tianqi , Zhang Yingying , Gao Lei , Zhang Yunhao
Published: December 2018

This study presents the Taguchi design method with L9 orthogonal array which was carried out to optimize the flux‐cored arc welding (FCAW) process parameters such as welding current, welding voltage, welding speed, and torch angle with reference to vertical for the ferrite content of duplex stainless steel (DSS, UNS S32205) welds. The analysis of variance (ANOVA) was applied, and a mathematical model was developed to predict the effect of process parameters on the responses. The results indicate that welding current, welding voltage, welding speed, torch angle with reference to vertical, and the interaction of welding voltage and welding speed are the significant model terms connected with the ferrite content. The ferrite content increases with the increase of welding speed and torch angle with reference to vertical, but decreases with the increase of welding current and welding voltage. Through the developed mathematical model, the target of 50% ferrite content in weld metal can be obtained when all the welding parameters are set at the optimum values. Finally, in order to validate experimental results, confirmation tests were implemented at optimum working conditions. Under these conditions, there was good accordance between the predicted and the experimental results for the ferrite content.
Optimization and Coordination of Crowdsourcing Supply Chain in Fast Fashion Industry
Authors: Li Jizi , Liu Chunling , Zeng Xianyi , Zhang Nian
Published: December 2018

Due to inadequate designers in fast fashion industry and the development of the Internet, small-and-medium-sized garment makers have gradually turned to external talents to enhance their new product design efficiency via crowdsourcing initiative. This paper presents a new framework of crowdsourcing supply chain for fast fashion industry. First, a basic multiperiod order model is established in a crowdsourcing supply chain system, where a garment maker chooses the best one among available solutions submitted by online designers (i.e., crowdsources) in each period, then transforms it into finished product, and sells to consumers through a retailer. Second, we extend this model by integrating the factors of capital turnover, the retailer’s risk-aversion, and the garment maker’s minimum production quantity. Moreover, utilizing wholesale price, buyback, and profit-sharing scheme designs a mixed contract for coordinating crowdsourcees, retailer, and garment maker of crowdsourcing supply chain for achieving Pareto optimality. The models help the garment maker determining the optimal production quantities of crowdsourcing designed products and enable the retailer placing the optimum orders and setting the reasonable risk level. In addition, we also find that the incentive policy for crowdsourcing designers can be fulfilled by using a profit-sharing scheme with a piecewise function of order quantity instead of a linear function.

Authors: Martino Luís Mauro Sá
Published: December 2018

Este artigo delineia as representações da vida acadêmica presentes nos quadrinhos PhD Comics, criada por Jorge Cham e publicada on-line desde 2006, focalizando os aspectos subjetivos da prática de pesquisa. Foram analisadas cerca de duas mil tiras, em diversos arcos narrativos. Observou-se, de um lado, as interações entre pesquisadores, orientadores e professores e, de outro, suas interações com as pesquisas. Três aspectos se destacam dentre as representações: (a) a estrutura hierárquica do ambiente universitário; (b) as disputas presentes no âmbito acadêmico; e (c) a tensão entre a vida pessoal e universitária dos pesquisadores. A representação crítica é, no entanto, feita de maneira leve, construindo um efeito de humor para quem está ou esteve no ambiente acadêmico.

Published: December 2018

Background

It is currently unknown whether 6 months of supervised treadmill exercise has a durable benefit on 6‐minute walk performance, even after exercise is completed, in people with peripheral artery disease.

Methods and Results

A total of 156 participants with peripheral artery disease were randomized to 1 of 3 groups: supervised treadmill exercise, supervised resistance training, or attention control. Participants received supervised sessions during months 1 to 6 and telephone contact during months 6 to 12. Primary outcomes were change in 6‐minute walk distance and short physical performance battery at 6‐month follow‐up and have been reported previously. Secondary outcomes were change in 6‐minute walk and short physical performance battery at 12‐month follow‐up and are reported here. A group of 134 participants (86%) completed the 12‐month follow‐up. At 6‐month follow‐up, compared with control, 6‐minute walk distance improved in the treadmill exercise group (+36.1 m, 95%
CI
=13.9‐58.3,
P
=0.001). Between 6‐ and 12‐month follow‐up, 6‐minute walk distance significantly declined (−28.6 m, 95% CI=−52.6 to −4.5,
P
=0.020) and physical activity declined −272 activity units (95%
CI
=−546 to +2,
P
=0.052) in the treadmill exercise group compared with controls. At 12‐month follow‐up, 6 months after completing supervised treadmill exercise, change in 6‐minute walk distance was not different between the treadmill exercise and control groups (+7.5, 95%
CI
=−17.5 to +32.6,
P
=0.56). There were no differences in short physical performance battery change between either exercise group and control at 6‐month or 12‐month follow‐up.

Conclusions

A 6‐month supervised treadmill exercise intervention that improved 6‐minute walk distance at 6‐month follow‐up did not have persistent benefit at 12‐month follow‐up. These results do not support a durable benefit of supervised treadmill exercise in peripheral artery disease.

Published: December 2018

Background

Racial/ethnic disparities in acute stroke care may impact stroke outcomes. We compared outcomes by race/ethnicity among elderly Medicare beneficiaries in hospitals participating in the FL‐PR CReSD (Florida–Puerto Rico Collaboration to Reduce Stroke Disparities) registry with those in hospitals not participating in any quality improvement programs (non‐
QI
) in Florida and Puerto Rico (PR).

Methods and Results

The population included fee‐for‐service Medicare beneficiaries age 65+ in Florida and
PR
, discharged with primary diagnosis of ischemic stroke (
International Classification of Diseases, Ninth Revision, Clinical Modification [ICD‐9‐CM],
codes 433, 434, 436) in 2010–2013. We used mixed logistic models to assess racial/ethnic differences in outcomes (in‐hospital, 30‐day, and 1‐year mortality, and 30‐day readmission) for
CR
e
SD
and non‐
QI
hospitals, adjusted for demographic and clinical characteristics. The study included 62
CR
e
SD
hospitals (N=44 013, 84% white, 9% black, 4% Florida Hispanic, 1%
PR
Hispanic) and 113 non‐
QI
hospitals (N=14 422, 78% white, 7% black, 5% Florida Hispanic, 8%
PR
Hispanic). For patients treated at
CR
e
SD
hospitals, there were no differences in risk‐adjusted in‐hospital mortality by race/ethnicity; blacks had lower 30‐day mortality versus whites (odds ratio, 0.86; 95% confidence interval, 0.77–0.97), but higher 30‐day readmission (hazard ratio, 1.09; 1.00–1.18) and 1‐year mortality (odds ratio, 1.13; 1.04–1.23); Florida Hispanics had lower 30‐day readmission (hazard ratio, 0.87; 0.78–0.98).
PR
Hispanic and black stroke patients treated at non‐
QI
hospitals had higher risk‐adjusted in‐hospital, 30‐day and 1‐year mortality, but similar 30‐day readmission versus whites treated in non‐
QI
hospitals.

Conclusions

Disparities in outcomes were less common in
CR
e
SD
than non‐
QI
hospitals, suggesting the benefits of quality improvement programs, particularly those focusing on racial/ethnic disparities.

Published: December 2018

Lepidocephalichthys (Telostei:Cobitidae) is diagnosed as being unique among cobitids in having the 7–8th pectoral rays of mature males modified. Recently collected material from Thailand included a new species of Lepidocephalichthys in which mature males have a large (extending over ~75% of the fin-ray length) dorsally projecting and serrated flange and a ventrally projecting flange. The ventrally projecting structure is unique among cobitids. An expanded phylogenetic analysis of cobitids, including previously published sequences and new material including the new species, reinforces the monophyly of Lepidocephalichthys. Relationships within southern lineages of cobitids, and the unusual habitat of the new species are discussed.

A new South American species of Banasa Stål (Hemiptera: Heteroptera: Pentatomidae: Pentatominae): from egg to adult
Authors: CAMPOS LUIZ ALEXANDRE , GRAZIA JOCELIA , DE ALMEIDA GARBELOTTO THEREZA , BIANCHI FILIPE MICHELS , LANZARINI NARA CORAL
Published: December 2018

Banasa maculata sp. nov. is described from a Brazilian Atlantic Forest, including immature stages and aspects of its life history. Adults and nymphs were reared in laboratory and fed on fruits of Miconia sellowiana (Melastomataceae). Eggs and first instars of B. maculata are similar to those of other species of Banasa; however, the color pattern of the abdomen distinguishes B. maculata, particularly first, fourth, and fifth instars. Light and dark morphs were observed for third, fourth, and fifth instars. Head-width measurements overlap only between fourth and fifth instars. Eggs of B. maculata, in S.E.M., show a reticulate pattern with deep cells and irregular rims. The most frequent size of an egg clutch was 12. Average duration of the immature stages (egg to adult) was 37.6 ± 13.24 days. The highest mortality occurred in the fifth instar (45.9%). Banasa maculata belongs to the “cuspidata group” of Banasa because of the presence of an apical projection of each posterolateral angle of the pygophore. Adults of B. maculata resemble B. varians Stål; the new species is recognized by the transversal, irregular, broad macula on pronotum; gonocoxites 8 deeply excavated medially; and the male proctiger subtriangular, narrowing toward the apex.

Published: December 2018

The predominantly Neotropical tribe Cryphocricini (Naucoridae: Cryphocricinae) comprises two described genera. Of these, the nominate genus, Cryphocricos (Signoret 1850), is widely distributed from Argentina north to Texas, and is represented by 14 described species (La Rivers 1971, 1974, 1976). This genus uses plastral ventilation (Parsons & Hewson 1974) and, thus, has drawn interest and been the subject of several associated studies of morphology and biology (Parsons 1974, Sites 1990, Sites & Nichols 1993, Lopez-Ruf et al. 2000).

Authors: GUIMARÃES RICARDO Z. P. , NUNAN GUSTAVO W. , GASPARINI JOÃO LUIZ
Published: December 2018

Malacoctenus brunoi n. sp., a scaled blenny endemic to Trindade Island, is distinguished from its southwest Atlantic congeners by the combination of a higher number of lateral-line scales (typically 62-66), a more elongated body (depth 19-22 % SL), and the presence of two longitudinal series of dark brown spots alongside the body.
Systematics and phylogeny of Cristacoxidae (Copepoda, Harpacticoida): a review
Authors: HUYS RONY , KIHARA TERUE CRISTINA
Published: December 2018

Both sexes of a new species of Noodtorthopsyllus Lang, 1965 (Harpacticoida, Cristacoxidae) from a sandy beach in São Paulo State (Brazil) are described using light and scanning electron microscopy. Noodtorthopsyllus tageae sp. nov. displays a mosaic of characters drawn from both Noodtorthopsyllus and Cristacoxa Huys, 1990, blurring the boundaries between both genera. Consequently, Cristacoxa, the type genus of the nominal family-group taxon Cristacoxidae Huys, 1990, is relegated to a junior subjective synonym of Noodtorthopsyllus, and its type species is transferred to the latter as N. petkovskii (Huys, 1990) comb. nov. A new genus Acuticoxa is proposed to accommodate A. ubatubaensis sp. nov. (type species), collected on the northern continental shelf of São Paulo State, and A. biarticulata sp. nov., previously identified as Laophontisochra sp., from the Northern Magellan Straits. Amended diagnoses are provided for Noodtorthopsyllus and Laophontisochra. Autapomorphies supporting the monophyly of the Cristacoxidae are re-evaluated, including new data on P3 endopod sexual dimorphism and caudal ramus development. It is concluded that a recently published hypothesis of a deeply rooted split of the family into two highly divergent lineages cannot be supported. Consequently, both Laophontisochra and Acuticoxa gen. nov. are removed from the Cristacoxidae and tentatively assigned to the Nannopodidae (ex Huntemanniidae), forming a clade with three other genera displaying coxal modifications on leg 1 (Rosacletodes Wells, 1985; Huntemannia Poppe, 1884; and an as yet undescribed genus from Brazil). Based on the sexual dimorphism of the P4 endopod, we propose to transfer Metahuntemannia Smirnov, 1946 and Pottekia Huys, 2009 from the Nannopodidae to the Canthocamptidae (subfamily Hemimesochrinae) where they are probably most closely related to Psammocamptus Mielke, 1975; Bathycamptus Huys & Thistle, 1989; Perucamptus Huys & Thistle, 1989; and Isthmiocaris George & Schminke, 2003. An identification key to the genera of the Nannopodidae is presented.
A new basal iguanodont (Dinosauria: Ornithischia) from the Wealden (Lower Cretaceous) of England
Authors: MCDONALD ANDREW T. , BARRETT PAUL M. , CHAPMAN SANDRA D.
Published: December 2018

A nearly complete right dentary originally noted by Mantell in 1848 is redescribed. The specimen, NHMUK 28660, was discovered in a quarry near Cuckfield, West Sussex, from the same formation as the original teeth of Iguanodon anglicus. Fresh examination reveals that NHMUK 28660 exhibits a single autapomorphy (a row of foramina extending from the ventral surface of the symphysis onto the lateral surface of the dentary) and a unique combination of characters that distinguish it from all other iguanodontian dentaries. In light of this and because I. anglicus is regarded as a nomen dubium to which additional material cannot be unambiguously referred, NHMUK 28660 is made the holotype of the new genus and species Kukufeldia tilgatensis.

The status of the athetine aleocharine genus Sableta Casey, 1910, and its previously included species, is reviewed. Sableta and Sa. infulata Casey, 1910, the single species remaining in the genus after others are reassigned, are described and illustrations of habitus, structural and genitalic features are provided. All species previously placed in Sableta are assigned to appropriate taxonomic categories. Sableta curata Casey, 1910 is transferred to Acrotona Thomson, 1859; Silusida nanella Casey, 1906, Sableta flaviventris Casey, 1910, Sa. longiclava Casey, 1910, Sa. immunis Casey, 1910 and Sa. remissa Casey, 1910 are transferred to Atheta Thomson, 1858. Homalota flaveola Melsheimer, 1844 is placed in synonymy with Hoplandria lateralis (Melsheimer, 1844) (Hoplandriini) and Sableta ornator Casey, 1910 is placed in synonymy with Atheta nanella (Casey, 1906). Synonymy of Sableta beatula Casey, 1910 and Atheta nanella (Casey, 1906) is confirmed.

Trichomycterus giganteus (Siluriformes: Loricarioidea: Trichomycteridae): a new catfish from the Rio Guandu basin, southeastern Brazil
Authors: LIMA SERGIO M.Q. , COSTA WILSON J.E.M.
Published: December 2018

Trichomycterus giganteus, new species, is described from the Rio Guandu basin, Serra do Mendanha, Rio de Janeiro city. Although being the biggest among species from southeastern Brazil and endemic to an older metropolitan area, it has gone unknown until the present, illustrating the poor knowledge of the taxonomy of this genus. It is distinguished from the remaining species of the genus by a combination of long nasal and maxillary barbels, a single median third supraorbital pore, long pectoral filament, nine pectoral-fin rays, high number of odontodes, relative position of the anal-fin origin, and a unique color pattern.

Description of the larval stages of the Shield Darter, Percina peltata (Pisces: Percidae), in New York
Authors: SCHMIDT ROBERT E. , DANIELS ROBERT A.
Published: December 2018

A series of larvae of Percina peltata (Pisces: Percidae) was collected from the Neversink River, a Delaware River tributary, in spring of 2001 and 2002. We provide descriptions and illustrations of yolk sac larvae and post yolk sac larvae through the end of larval development. The larval morphology of P. peltata is plesiomorphic for the clade of the Etheostomatinae which we correlate with the plesiomorphic position afforded P. peltata in other studies. We do not consider the larval morphology of this species to be an adaptation to its environment.

The Xixuthrus species of Fiji (Coleoptera: Cerambycidae:) Prioninae
Authors: YANEGA DOUGLAS , OLSON DAVID , SHUTE SHARON , KOMIYA ZIRO
Published: December 2018

There have been four species of the cerambycid genus Xixuthrus described from the Fijian archipelago; X. heros (Heer), X. terribilis Thomson, X. ganglbaueri Lameere, and X. heyrovskyi Tippmann. Over time, X. terribilis had been reduced to synonymy, and it had been suggested that X. ganglbaueri was probably from New Guinea rather than Fiji. We here re-establish the validity of X. terribilis, place X. heyrovskyi in synonymy with it, and designate a neotype for X. ganglbaueri to resolve both the species identity and its geographic provenance. Diagnoses of the three confirmed Fijian species are presented, including digital images of type specimens, and notes on temporal and spatial distribution.
Impact of Aerosol Shortwave Radiative Heating on Entrainment in the Atmospheric Convective Boundary Layer: A Large-Eddy Simulation Study
Authors: Liu Cheng , Fedorovich Evgeni , Huang Jianping , Hu Xiao-Ming , Wang Yongwei , Lee Xuhui
Published: December 2018

Entrainment is critical to the development of the atmospheric convective boundary layer (CBL), but little is known about how entrainment is impacted by the aerosol radiative effect. An aerosol radiation transfer model is used in conjunction with large-eddy simulation (LES) to quantify the impact of aerosol shortwave radiative heating on entrainment and thermodynamics of an idealized dry CBL under aerosol-loading conditions. An entrainment equation is derived within the framework of a zero-order model (ZOM) with the aerosol radiative heating effect included; the equation is then examined against the LES outputs for varying aerosol optical depths (AODs) and free-atmosphere stratification scenarios. The results show that the heat flux profiles become more nonlinear in shape as compared to the case of the clean (no aerosol pollution) CBL, with the degree of nonlinearity being highly dependent on the AOD of the layer for the given type of radiation-absorbing aerosols. As AOD increases, less solar radiation reaches the surface and thus the surface heat flux becomes smaller, and both actual (LES) and ZOM-derived entrainment flux ratios decrease. This trend is opposite to the clean CBL where the LES-predicted flux ratios show an increasing trend with diminishing surface heat flux, while the ZOM-calculated flux ratio remains constant. The modified dimensionless entrainment rate closely follows the −1 power law with a modified Richardson number. The study suggests that including the aerosol radiative effect may improve numerical air quality predictions for heavy-air-pollution events.
A Service-Learning Initiative to Teach Hands-Only CPR to High School Students: PumpStart
Authors: Kalluri Nikita S. , Knopov Anita , Kue Ricky
Published: December 2018

Out-of-hospital cardiac arrest (OHCA) survival rates have been shown to be lower than cardiac arrest survival rates occurring in the hospital setting. Bystander cardiopulmonary resuscitation (CPR) can significantly improve survival. PumpStart, a community service-learning program developed by medical students, was formed to increase education on compression-only CPR to local high school students and foster leadership and mentorship skills in participating medical students. 1-hr sessions were administered at local high schools throughout the metro—Boston area. A single semester “pilot” phase and “first-year” implementation phase were reviewed. Anonymous pre-/postassessment surveys were completed by participants. Medical students also completed surveys assessing their comfort in teaching CPR. Surveys over both pilot semester and first year phases were reviewed. Participants reported significant improvements in CPR technique and confidence in acquired skills for both the pilot semester (31% vs. 82%, p < .05) and first year implementation (33% vs. 86%, p < .05). Medical students reported significantly higher confidence levels regarding abilities to answer questions about CPR, serving as mentors, and facilitating training sessions for new medical students after participating in PumpStart ( p < .05). PumpStart was successful in providing CPR awareness to high school students, as well as the opportunity to learn about teaching and mentoring for medical students. Such a program can be easily reproduced by other health care organizations with the goal to increase opportunities for bystander CPR and improving OHCA survival rates nationally.
