When Traffic Flow Meets Power Flow: On Charging Station Deployment With Budget Constraints

The lack of charging facilities has been a main obstacle to the widespread use of electric vehicles (EVs). What is worse is that existing chargers are still underutilized. Meanwhile, the grid instability caused by EV charging is becoming much more significant with increasing EV penetration. This paper studies how to size and locate charging stations in traffic networks considering grid constraints to balance the charging demand and power network stability. First, a spatiotemporal model of charging demand is proposed, and a <inline-formula><tex-math notation="LaTeX">$\text{1}-(\text{1}/e)$</tex-math></inline-formula> approximation algorithm to maximize the charging demand is designed. We analytically prove that <inline-formula><tex-math notation="LaTeX">$\text{1}-(\text{1}/e)$</tex-math></inline-formula> is the best bound that can be obtained in polynomial time. Then, a linearized power network model (LPNM) is proposed. Based on LPNM, a heuristic algorithm involving the grid constraints (HAG) is designed. Finally, the proposed models and algorithms are evaluated on real-world traffic networks and power networks. The relative error of the voltage deviation estimated by LPNM is about 4%. Compared with the plain demand model, adopting the spatiotemporal charging demand model improves the utilization of chargers by 5% at least. Compared with the greedy algorithm with grid constraints (GAG), HAG improves the carrying capacity of the power network by 20.7%, reduces the voltage deviation by 25%, and increases the EVs charged by 18.07%.
Production of chickens with marginal vitamin A deficiency

Marginally vitamin A-deficient 1-d-old chickens capable of remaining healthy for at least 6 weeks were produced using a two-generation model. In this model, hens fed on diets with a limited vitamin A content were used to obtain 1-d-old chickens which were marginally deficient in vitamin A. Only hens with a narrow range of plasma retinol values (0.60–0.85 μmol/l) were satisfactory for this purpose. Above this range the 1-d-old chickens were not marginally vitamin A deficient. Below this range egg production and hatchability were affected to some extent depending on the degree of vitamin A deficiency. Even when egg production and hatchability remained at a high level in such birds, the 1-d-old chickens produced were not sufficiently strong to survive the first weeks of life. The advantages of the two-generation model for producing marginally vitamin A-deficient chickens are the increased uniformity and predictability of the chickens with respect to body-weight, general health and vitamin A status. However, it does take about 3 months to produce such chickens.
An Analysis of Specific Lower Extremity Injury Rates on Grass and FieldTurf Playing Surfaces in National Football League Games

Background: Players in the National Football League (NFL) sustain injuries every season as the result of their participation. One factor associated with the rate of injury is the type of playing surface on which the players participate. Hypothesis: There is no difference in the rate of knee sprains and ankle sprains during NFL games when comparing rates of those injuries during games played on natural grass surfaces with rates of those injuries during games played on the artificial surface FieldTurf. Study Design: Descriptive epidemiology study. Methods: The NFL records injury and exposure (ie, game) data as part of its injury surveillance system. During the 2000-2009 NFL seasons, there were 2680 games (5360 team games) played on grass or artificial surfaces. Specifically, 1356 team games were played on FieldTurf and 4004 team games were played on grass. We examined the 2000-2009 game-related injury data from those games as recorded by the injury surveillance system. The data included the injury diagnosis, the date of injury, and the surface at the time of injury. The injury data showed that 1528 knee sprains and 1503 ankle sprains occurred during those games. We calculated injury rates for knee sprains and ankle sprains—specifically, medial collateral ligament (MCL) sprains, anterior cruciate ligament (ACL) sprains, eversion ankle sprains, and inversion ankle sprains—using incidence density ratios (IDRs). We used a Poisson model and logistic regression odds ratios to validate the IDR analysis. A multivariate logistic regression model was used to adjust the odds ratio for weather conditions. Results: The observed injury rate of knee sprains on FieldTurf was 22% (IDR = 1.22, 95% confidence interval [CI], 1.09-1.36) higher than on grass, and the injury rate of ankle sprains on FieldTurf was 22% (IDR = 1.22, 95% CI, 1.09-1.36) higher than on grass. These differences are statistically significant. Specifically, the observed injury rates of ACL sprains and eversion ankle sprains on FieldTurf surfaces were 67% (P < .001) and 31% (P < .001) higher than on grass surfaces and were statistically significant. The observed injury rates of MCL sprains and inversion ankle sprains were also not significantly higher on FieldTurf surfaces (P = .689 and .390, respectively). Conclusion: Injury rates for ACL sprains and eversion ankle sprains for NFL games played on FieldTurf were higher than rates for those injuries in games played on grass, and the differences were statistically significant.
Vasoactive Intestinal Peptide Interacts with Alpha-adrenergic-, Cholinergic-, and Substance-P-mediated Responses in Rat Parotid and Submandibular Glands

Secretory dose-response curves were obtained with both acetylcholine and phenylephrine treatment in rat parotid and submandibular glands. Vasoactive intestinal peptide (VIP), which produced relatively low volumes of protein-rich saliva in rat salivary glands, also enhanced acetylcholine-, phenylephrine-, and substance-P-mediated fluid and protein secretion when administered in combination with these agents. The specific mechanisms involved in the synergistic actions of VIP with substances such as acetylcholine, phenylephrine, and substance P, which are primarily linked to the production of fluid secretion in rat salivary glands, have yet to be determined.
Curricular Requirements for Musculoskeletal Medicine in American Medical Schools

A fundamental knowledge of the musculoskeletal system and its disorders is necessary for most practicing physicians, regardless of their specialty. Disorders of the musculoskeletal system are the primary reason that individuals seek medical attention in the United States 1,2. Nonetheless, there is evidence that medical students are not well prepared in this area. Freedman and Bernstein 3 administered a basic-competency examination comprising twenty-five questions on musculoskeletal medicine to a group of eighty-five recent medical school graduates. The examination was validated by 124 chairmen of orthopaedic departments, and a passing grade of 73.1% was set. With use of this criterion, 82% were found to have failed the examination. The examination was further validated by the directors of medical residency programs, and a comparable passing score was set 4. Moreover, Clawson et al. 5 surveyed 5487 second-year residents in United States allopathic and osteopathic residency programs and found that many considered themselves ill-prepared in the area of musculoskeletal medicine. On the basis of these reports, it is reasonable to believe that medical students in the United States are not receiving the instruction in musculoskeletal medicine that they need. We hypothesized that if preparation in musculoskeletal medicine is indeed inadequate, a lack of required curricular time devoted to these subjects may be the cause. Therefore, we assessed the extent to which American medical schools require either a preclinical course in musculoskeletal medicine or a clinical clerkship in a related field, namely, orthopaedic surgery, rheumatology, or physiatry (physical medicine and rehabilitation). Curriculum data were obtained from the 122 medical schools in the continental United States and Hawaii. The American Association of Medical Colleges web site, www.aamc. org, provided links to the web sites of all medical schools in the United States. Data were obtained directly from curriculum information published on the …
On Presenting Russian Stress

How vocabulary items are presented in textbooks of Russian is a matter of concern to teachers and students alike. Teachers benefit from a clear and comprehensible system which simplifies the task of teaching inflectional morphology and frees time and energy for other classroom work. Students can improve both their practical command of Russian and their understanding of its structure from a system which shows them most clearly how the language works. An examination of existing Russian textbooks, however, reveals the lack of a universally accepted presentation of vocabulary items. Most commonly used are the traditional citation forms found in dictionaries: the nominative singular form of nouns, the masculine nominative singular form of adjectives, and the infinitive form of verbs. Unfortunately, these forms often do not provide adequate information to allow the proper inflection of the word, and additional forms of the paradigm must be cited. For presenting the Russian verb, the authors of at least two recent textbooks employ an adaptation of the single-stem system proposed by Roman Jakobson in 1948.1 This approach differs from the traditional in that only a single citation form is used, which carries a diacritic mark indicating stress behavior throughout the paradigm. This citation form, which allows the student to produce any form of the paradigm by the proper application of rules and interpretive conventions, will consequently be an abstract representation rather than a concrete member of the paradigm.

Secondary Traumatization in Pediatric Healthcare Providers: Compassion Fatigue, Burnout, and Secondary Traumatic Stress

The primary aim for this research was to explore the overlap and differences between the concepts related to secondary traumatization: posttraumatic stress disorder (PTSD), secondary traumatic stress (STS), compassion fatigue (CF), and burnout (BRN). A secondary aim for this research was to examine the impact of secondary traumatization and some of the personal and professional elements that affect how pediatric healthcare providers experience PTSD, STS, CF, and BRN. An online survey was sent via e-mail to numerous list serves for healthcare providers who had worked on PICU, NICU, or PEDS units within the last year. The analyses revealed that a significant overlap existed between the terms of STS, PTSD, BRN, CS, and CF for PICU, NICU, and PEDS providers. However, a hierarchical linear regression revealed a significant amount of unique contributions to the variance in CF based on each of the measured concepts. Despite previous literature that indicates that the terms STS and CF can be used interchangeably, the two most prominent measures utilized in the assessment of CF and STS are actually capturing at least some unique elements. Given these results, future researchers should examine and conceptualize the difference in etiology, prevalence, symptoms, and treatment efficacy for CF and STS as separate but related entities and then return their focus to understanding secondary traumatization in healthcare providers.
An Insight into the Key Motivational Influences Responsible for the Adoption of Cryptocurrency Among Irish Male Millennials

Over the past twelve months, cryptocurrency has become an extremely popular alternative to the traditional monetary institutions, particularly among millennial males. The entire market-cap of the cryptocurrency industry grew roughly 5000% in 2017, resulting in all-time market highs that completely shocked the entire financial industry. The research was undertaken of this contemporary topic in an attempt to understand the primary determinants responsible for causing the abrupt surge in the adoption of this new technology which is still considered to be in its infancy. To ensure an effective analysis of this phenomenon, a comprehensive review of previous literature on disruptive innovation and the relationship between male millennials and technology adoption was carried out. In addition to this, numerous technology adoption models were examined and critiqued in order to identify the most appropriate framework which would assist in guiding the data gathering process. The Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) model was specifically adapted for the purposes of this study as it was identified as the most relevant and efficient model in assessing the adoption of cryptocurrency amongst Irish male millennials. Ten Irish male millennial’s who own cryptocurrency were contacted and open-ended interviews were conducted with the guidance of the adapted UTAUT2 model to develop an understanding for the motivating influences responsible for their adoption of this new phenomenon. The findings are discussed and critiqued in conjunction with the literature to develop some interesting insights and conclusions. Additionally, further areas of research are identified which will be required as this technology continues to grow and gains greater levels of worldwide adoption.
Realistic pseudoscalar-vector chiral Lagrangian and its soliton excitations.

A reasonable low-energy chiral Lagrangian of vectors and pseudoscalars involves three a priori unknown coefficients for terms proportional to the Levi-Civita symbol epsilon/sub . mu. //sub . nu. //sub . cap alpha. //sub . beta. /. We argue that these cannot, from a theoretical standpoint, be reliably determined by consideration of electromagnetic processes. Hence we use purely strong-interaction processes which enable us to determine two out of three of these. We examine the nucleon as a soliton excitation in the model and find that adjustment of the third parameter does not greatly change the, in most respects accurate, description of the nucleon obtained in a previous treatment by Meissner, Kaiser, and Weise. The paper includes a new and careful formulation of the addition of electromagnetism to the full Lagrangian.
Pulmonary arterial hypertension in a child with stage‐IV neuroblastoma after autologous hematopoietic stem cell transplantation and review of the literature

PH is a rare condition with high mortality rate after pediatric HSCT. As clinical presentation is non‐specific and may mimic other conditions, a high degree of suspicion is required for diagnosis. Here, we present a patient with stage‐IV neuroblastoma who developed PAH after autologous HSCT. After exclusion of other causes of PH, we regarded that this condition was secondary to HSCT.
Neuroradiologic findings in polyarteritis nodosa.

PURPOSE To demonstrate the neuroradiologic findings in patients with polyarteritis nodosa. METHODS A review of hospital records for a 10-year period revealed 50 patients with a discharge diagnosis of polyarteritis nodosa. Thirteen patients had undergone neuroimaging, and abnormal findings were found in 5 cases; these were the subjects of this study. RESULTS All 5 patients had abnormal findings on CT scans, 3 had abnormal findings on MR images, and 1 had an abnormal finding on a cerebral angiogram. All patients had cerebral cortical or subcortical infarctions, and 1 also had small infarctions within the brain stem and cerebellum. One patient had cerebral angiographic findings of arteritis. The diagnosis of arteritis was considered probable or possible in 3 other patients. Three patients had echocardiographic evidence of concentric hypertrophy and a hypocontractile left ventricle resulting from polyarteritis nodosa-related hypertension. Cardiogenic embolism was considered the likely cause in 1 patient. CONCLUSION Small peripheral cerebral infarctions, consistent with an arteritis involving medium-sized and small arteries, were the most common finding. However, cardiogenic embolism should also be considered as a possible cause of cerebral infarction in patients with polyarteritis nodosa who have left ventricular dysfunction.
ISO55000 Standard as A Driver for Effective Maintenance Budgeting

Companies are suffering from major industrial disasters, financial crisis and continued global instability caused by civil unrest and economic pressure.With the attendant issues associated with the increased economic and market globalization comes the criticality of standards and its role in, increasing productivity and efficiency, decreasing non-value-added information and promoting process through structured asset management techniques. The International Standard for Organization (ISO 55000) was developed specifically for Asset Management (AM), which consists of a series of three components, ISO 55000, ISO 55001 and ISO 55002. ISO 55000 takes a holistic approach to asset management; it is not just about maintenance but also about value creation. ISO 55000 requires changes in policy, processes and people thereby challenge the status quo and it leads to a new regime of asset care. Asset care requires organizations to comply with standards and various regulations. Adopting ISO 55000 will allow organization to align the way assets are managed and maintained, it improves return on investments by reducing costs, while supporting asset value without sacrificing organizational objectives. Maintenance and reliability processes, programs are aligned with ISO 55000, and span the entire life cycle of the assets including design, engineering, procurement, installation, start-up, operation, maintenance, restoration, decommissioning, and disposal. A popular term for the process is 'from cradle to grave'. Physical assets are often taken for granted and with increased reliability. Managing assets today is more complex, yet in many organizations, the management of those assets is often unfocused and inappropriate. Organizations with a strong profit focus need to examine ISO 55000 from the perspective of finding methods to leverage it into lower costs and increased outputs. The aim of this paper is to classify the necessary elements in ISO 550000, which organizations need to adopt in order to improve their approach to asset maintenance budgeting. It will highlight the main issues that need to be addressed when implementing ISO 55000 standard.
Single RGB Image Depth and Certainty Estimation via Deep Network and Dropout

Depth estimation is a useful technique for multiple applications such as obstacle detection and scene reconstruction. With the research focus on Convolutional Neural Networks (CNN), depth estimation has seen rapid development recently. Our contribution is a practical system which can inference depth from single RGB image with a measure of model uncertainty. Monte Carlo sampling with dropout at test time was used as a way of getting samples from the posterior distribution of models. By adding dropout at test time, we not only obtained the uncertainty map of our prediction, but also improved the performance of the original depth prediction task. Moreover, by testing with adding dropout after various layers, we find that adding dropout layers after every encoder convolutional layer shows potential in generating representative posterior distribution. This idea can also be applied in other neural network architecture.
Molecular typing of methicillin-resistant Staphylococcus aureus strains by PCR-RFLP of SPA gene: a reference laboratory perspective.

PURPOSE To characterize methicillin-resistant Staphylococcus aureus (MRSA) strains by molecular typing based on polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) of spa gene and to assess the utility of spa genotyping over bacteriophage typing in the discrimination of the strains. MATERIALS AND METHODS Studies were undertaken on 125 MRSA strains representing the most predominant phage types and the non phage typeable strains. Strains were typed by bacteriophage typing and PCR-RFLP of spa gene. DNA sequence analysis of the amplified spa gene fragment of the representative RFLP patterns was performed using standard protocols. RESULTS All the strains resistant to oxacillin were found to contain mec A gene. Fifty-two per cent of these strains were typeable by the international basic set of 23 phages. Five different PCR-RFLP patterns were observed among 125 MRSA strains. Non phage typeable strains were differentiated into four PCR-RFLP patterns. Sequencing of the spa gene from the representative strains of each RFLP pattern confirmed the length of these restriction fragments due to variation in the 24 bp and the 174 bp tandem repeats. It also revealed the presence of three new spa repeat patterns. CONCLUSION The study demonstrates the importance of spa genotyping in the discrimination of MRSA strains, which were otherwise indistinguishable by bacteriophage typing. spa genotyping allowed differentiation of strains within a particular phage type. Nucleotide sequencing of isolates of different PCR-RFLP patterns indicated a correlation between the RFLP patterns of a variable number of tandem repeats and the phage type. The study provides valuable information on the epidemiological characterization of MRSA strains.
Conflicts in Routing and UAV Autonomy

Routing is very fundamental to the implementation of any networking or communications infrastructure. This paper, therefore, examines the conflicts and relevant considerations for implementing autonomous or self-organising unmanned aerial vehicles (UAVs) for communications area coverage, with particular emphasis on the impact of aerial vehicle autonomy algorithms on routing techniques for such networks. UAV networks can be deployed either as ad-hoc or infrastructure-based solutions. The mobility of UAVs introduces periodic topology changes, impacting link availability and routing paths. This work examines the implications of autonomous coordination of multiple UAVs on routing techniques and network architecture stability. The paper proposes a solution where routing techniques and UAV autonomy algorithms are integrated for improved global network efficiency for both ad-hoc and infrastructure-based scenarios. Integrating UAV autonomy algorithms with routing schemes may be an efficient method to mitigate link/topology stability issues and improve inter-UAV communication and network throughput, a key requirement for UAV networks. The implementation of inter-UAV links using optical, microwave or mmWave transmission is examined in the context of this work. The proposed integration may be crucial for communications coverage, where UAVs provide communications area coverage of a community of mobile or fixed users in either ad-hoc or infrastructure-based modes.
VisuaLRTC: A New View on Lateral Root Initiation by Combining Specific Transcriptome Data Sets1[W]

Lateral root initiation and development has been increasingly studied over the last two decades. This postembryonic organogenic process guarantees the spatial development and plasticity of the root system in response to environmental cues and is crucial for the plant's growth and development. Several independent large-scale transcriptome studies in different species resulted in a wealth of data that can be instructive to understand this process at the molecular level. Here, we present an easy and flexible spreadsheet tool, called Visual Lateral Root Transcriptome Compendium, that combines publicly available data sets involved in Arabidopsis (Arabidopsis thaliana) lateral root development and links them with additional information on tissue-specific expression and cell cycle involvement, thus allowing the extraction of novel information from existing data sets in a visual and user-friendly manner. We believe that this tool will be valuable not only for root biologists but also for a broader range of scientists as it enables a fast indication of the potential involvement of a given gene during de novo organogenesis.
