Work-in-Progress: PowerMonitor: Design Pattern for Modelling Energy-Aware Embedded Systems

This paper introduces a new software design pattern that can be applied to embedded systems. The pattern enables the application to access the peripheral devices under defined power conditions and allows to implement a fine-grained and energy-efficient strategy on using functional units of the microcontroller. The approach considers power consumption properties of the CPU itself as well as properties of external peripheral devices like connected sensors and actuators.

Excitation and Damping Fluid Forces on a Cylinder Undergoing Vortex-Induced Vibration

In the context of flow-induced vibration, the component of the hydrodynamic coefficient in-phase with the velocity of an oscillating body, $C_v$, can be termed `positive excitation' or `negative damping' if $C_v>0$. While this empirical approach is of long standing in the literature it does not account for distinct physical mechanisms that can be associated with fluid excitation and fluid damping. In this work, we decompose the total hydrodynamic force into a drag component aligned with the time-dependent vector of the relative velocity of a cylinder oscillating transversely with respect to a free stream and a lift component normal to the drag component. The drag and lift components are calculated from laboratory measurements of the components of the hydrodynamic force in the streamwise and cross-stream directions combined with simultaneous measurements of the displacement of an elastically mounted rigid circular cylinder undergoing vortex-induced vibration. It is shown that the drag component only does negative work on the oscillating cylinder, i.e.\ it is a purely damping force as expected from theoretical considerations. In contrast to this the lift component mostly does positive work on an oscillating cylinder, i.e.\ it is the sole component providing fluid excitation. In addition, the new excitation (lift) coefficient, $C_L$ displays the same scaling as the linear theory predicts for the traditional excitation coefficient, $C_v$, even though $C_L$ is two orders of magnitude higher than $C_v$. More importantly, while $C_v$ depends on the mechanical properties of the hydro-elastic system, according to linear theory, we provide here evidence that $C_L$ depends solely on fluid-dynamical parameters. Finally, an effective drag is calculated that represents the dissipation of energy within the fluid, and it is found that the effective drag is not equal to the mean value of the drag component. The effective drag provides complementary information that characterizes the state of the wake flow. Its variation suggests that the wake can dissipate the kinetic energy most vigorously at the end of the initial branch.
An Innovative Autonomous and Semiautonomous Cars Communication Framework: An Environment Perception Perspective

Autonomous vehicles are equipped with multiple sensors that allow perception of the road environment. However, there are always challenges in terms of measurement accuracy, dynamics of the road driving conditions, and extended perception availability. Vehicular communication technologies have already been extensively researched, and the IEEE 802.11p standard has been approved. Therefore, communications could help in extending the perception of the autonomous vehicles if proper information transmission mechanisms are utilized. In fact, this paper proposes a novel and innovative design that will allow vehicles to extend their perception by exchanging a smaller number of packets than needed and estimate the actual perception of the environment. First, we propose a novel MAC layer that is compatible with the IEEE 802.11p standard that allows vehicles to recover extra perceptional areas of the environment as they receive new packets. Second, we demonstrate that this approach will result in a better utilization of the communication channel and acceptable perception accuracy of the environment, compared to transmitting the complete information.
SEVA 3.0: an update of the Standard European Vector Architecture for enabling portability of genetic constructs among diverse bacterial hosts

Abstract The Standard European Vector Architecture 3.0 database (SEVA-DB 3.0, http://seva.cnb.csic.es) is the update of the platform launched in 2013 both as a web-based resource and as a material repository of formatted genetic tools (mostly plasmids) for analysis, construction and deployment of complex bacterial phenotypes. The period between the first version of SEVA-DB and the present time has witnessed several technical, computational and conceptual advances in genetic/genomic engineering of prokaryotes that have enabled upgrading of the utilities of the updated database. Novelties include not only a more user-friendly web interface and many more plasmid vectors, but also new links of the plasmids to advanced bioinformatic tools. These provide an intuitive visualization of the constructs at stake and a range of virtual manipulations of DNA segments that were not possible before. Finally, the list of canonical SEVA plasmids is available in machine-readable SBOL (Synthetic Biology Open Language) format. This ensures interoperability with other platforms and affords simulations of their behaviour under different in vivo conditions. We argue that the SEVA-DB will remain a useful resource for extending Synthetic Biology approaches towards non-standard bacterial species as well as genetically programming new prokaryotic chassis for a suite of fundamental and biotechnological endeavours.
Low-dose epirubicin inhibits ezrin-mediated metastatic behavior of breast cancer cells

Aims and background Overexpression of ezrin contributes to the progression and invasiveness of several human cancers; however, its role in breast cancer metastasis has not been investigated in detail. Methods Ezrin expression in tissue samples from patients with invasive ductal carcinoma of the breast was detected by immunohistochemistry. Ezrin expression in a breast cancer cell line was evaluated using Western blot and RT-PCR. Results Elevated expression of ezrin was associated with lymph node metastasis and poor prognosis in patients with invasive ductal carcinoma. Ezrin expression was related to the invasiveness of breast cancer cells in vitro. Low-dose epirubicin inhibited the migration of breast cancer cells in a concentration-dependent manner without promoting cytotoxicity in vitro and decreased the expression of ezrin in a concentration-dependent manner. Conclusions Low-dose epirubicin may be antimetastatic without promoting cytotoxic effects and could serve as a target for the development of therapeutics for breast carcinoma.
Low Vitamin D is associated with Coronary Atherosclerosis in Women with HIV

Background Vitamin D deficiency is underdiagnosed and undertreated, especially among people living with HIV (PLWH). Recently, there has been an increased interest in the role of vitamin D in cardiovascular disease (CVD). While vitamin D deficiency has been associated with CVD in observational studies in the general population, there are limited data in PLWH. We therefore performed an analysis to assess the relationship of vitamin D and coronary atherosclerosis using coronary CT angiography (CCTA). Methods Women living with HIV (WLWH) without known CVD were included. Based on the median value of serum vitamin D levels, participants were dichotomized to either the <25 ng/ml (lower vitamin D group) or ≥25 ng/ml (higher vitamin D group). CCTA was used to assess plaque characteristics. Results Forty-three WLWH were included in the analyses (mean age 46 ±8 years, 56% African American, duration of HIV 15 ±6 years, 83% undetectable HIV viral load). WLWH in the lower vitamin D group (n=22) had significantly higher numbers of segments with any coronary plaque (2.27 ±3.01 versus 0.38 ±0.97; P=0.02) and segments with non-calcified coronary plaque (1.41 ±1.82 versus 0.29 ±0.64; P=0.03) compared with WLWH in the higher vitamin D group (n=21). After adjusting for Framingham CHD risk point score, body mass index, diabetes and race, the relationship remained significant. Conclusions Our study demonstrates a significant, independent relationship between lower vitamin D status and higher numbers of noncalcified coronary plaque segments in WLWH. Further studies are warranted to evaluate the effect of vitamin D on CVD in PLWH. Trial Registration Identifier: NCT00455793.
Transition-Age Young Adults with Cerebral Palsy: Level of Participation and the Influencing Factors

Background and Objectives: The aim of this study was to identify the level of participation in the context of the developmental transition from adolescence to adult life for young adults with cerebral palsy (CP) and the factors that had an influence on participation. Materials and Methods: Eighty-one young adults (16–21 years old) with CP and with normal or slightly decreased cognitive function participated in this study. Assessments were made using the Rotterdam Transition Profile (RTP) and the WHO Disability Assessment Schedule 2.0 (WHODAS 2.0). In the binary regression model, levels of participation (RTP scores) were set as dependents and the level of disability (WHODAS 2.0 scores), age, and level of gross motor function were set as independent variables. Results: In the age group <18 years, in three out of seven RTP domains, less than 10% of participants were in phase 2 (experimenting and orientating toward the future), i.e., finance—7%, housing—7%, sexuality—4%. In the age group ≥18 years, 21% (education and employment), 56% (intimate relationships), and 59% (sexuality) of the participants were in phase 0 (no experience). Higher scores in WHODAS 2.0 domains showed positive associations with RTP domains, i.e., cognition with social activities, mobility with transportation, self-care with sexuality and transportation, and life activities with transportation. Age was positively associated with education and employment, finance, housing, and sexuality. Low motor function according to the Gross Motor Function Classification System (GMFCS) had negative associations with autonomy in social activities, sexuality, and transportation. Conclusions: Young adults with cerebral palsy showed low levels of autonomy in all domains of participation. When addressing a person’s improvement in terms of their participation, the promotion of abilities in cognition, mobility, self-care, and life activities should be attempted. Age and gross motor function influenced autonomy in participation, but not in all domains.
The POSEIDON Criteria and Its Measure of Success Through the Eyes of Clinicians and Embryologists

This article represents a viewpoint on the POSEIDON criteria by a group of clinicians and embryologists. Its primary objective is to contextualize the Poseidon criteria and their metric of success for the relevant Frontiers Research Topic “POSEIDON's Stratification of Low Prognosis Patients in ART: The WHY, the WHAT, and the HOW”. “Low prognosis” relates with reduced oocyte number, which can be associated with low or sometimes a normal ovarian reserve and is aggravated by advanced female age. These aspects will ultimately affect the number of embryos generated and consequently, the cumulative live birth rate. The novel system relies on female age, ovarian reserve markers, ovarian sensitivity to exogenous gonadotropin, and the number of oocytes retrieved, which will both identify the patients with low prognosis and stratify such patients into one of four groups of women with “expected” or “unexpected” impaired ovarian response to exogenous gonadotropin stimulation. Furthermore, the POSEIDON group introduced a new measure of clinical success in ART, namely, the ability to retrieve the number of oocytes needed to obtain at least one euploid blastocyst for transfer in each patient. Using the POSEIDON criteria, the clinician can firstly identify and classify patients who have low prognosis in ART, and secondly, aim at designing an individualized treatment plan to maximize the chances of achieving the POSEIDON measure of success in each of the four low prognosis groups. The novel POSEIDON classification system is anticipated to improve counseling and management of low prognosis patients undergoing ART, with an expected positive effect on reproductive success and a reduction in the time to live birth.
Developing a Model for Accreditation of Iranian Teaching Hospitals: A Qualitative Study

Background Among different factors, accreditation is being widely used across the world to improve quality and safety in hospitals. Therefore, the purpose of the present study was to develop an accreditation model for teaching hospitals in Iran. Methods This qualitative study was conducted in four phases from January, 2017 to March, 2018. To this end; firstly, existing accreditation models were extracted and reviewed comparatively. Within the second stage, dimensions and components of the accreditation model were extracted through semi-structured interviews. In the third stage, a new instruction was developed via integrating the findings from the first and the second stages. Finally, the model was validated in two phases of Delphi method and a specialized forum in the fourth step. Qualitative findings were then analyzed using content analysis method. Results Models of Joint Commission International (JCI) and Word Federation for Medical Education (WFME) in other 6 countries were reviewed and compared with the current Iranian model. Extracted dimensions discovered to complement the present model included learner assessment, continuous reviews and revisions, and educational productivity. The final model was also developed with 12 dimensions and 94 standards. Content validity ratio (CVR) and content validity index (CVI) were also estimated to be 0.40 and 0.80, respectively. As well, the second round of Delphi method could increase the number of model standards to 97. Moreover, Cohen's kappa coefficient was calculated to be at least 0.71. Conclusion This study led to the development of a comprehensive model for scientific accreditation of teaching hospitals through reviewing documentation, combining and comparing global approaches, as well as integrating them with the views of domestic experts.
Ciliary force-responsive striated fibers promote basal body connections and cortical interactions

Soh et al. study the organization of Tetrahymena ciliary arrays. Basal body–associated striated fibers organize motile cilia by promoting basal body orientation, reorientation, and resistance to ciliary forces. To do so, striated fiber length is modulated to ensure connections between neighboring basal bodies and to the cell cortex.
A systematic review of psychometric assessment of the Jefferson Scale of Empathy using the COSMIN Risk of Bias checklist.

INTRODUCTION Empathic communication in health care may enhance positive patient and health care professional relationships, patient satisfaction and can buffer professional burnout. The Jefferson Scale of Empathy (JSE) was developed based on the need to quantitatively measure levels of empathy, particularly in health care settings. Evaluating the utility of empathy is underpinned by the psychometric rigour of the instruments used to measure it. The aim of this study was to critically evaluate the current evidence on the measurement properties of the JSE. METHODS Two reviewers independently searched six databases for papers describing psychometric assessment of the JSE from January 2000 to July 2018 inclusive. The studies were independently assessed for methodological quality using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) Risk of Bias checklist. RESULTS The search strategy resulted in the retrieval of 985 papers, of which 59 were included in this study. The majority of papers reported on measures of structural validity and internal consistency, and it was in these areas which the highest quality of reporting was demonstrated. Additionally, there was a generally very good quality in reporting of convergent validity. Reliability, measurement error, cross-cultural validity were reported with less than optimum quality. CONCLUSION The JSE demonstrates robust structural validity, internal consistency, and convergent validity. These measurement properties are generally well reported in the literature in studies of good methodological quality, and thus may be interpreted with relative confidence when used in empathy research. However, current evidence is limited for the properties of reliability, measurement error, and cross-cultural validity. Thus, a degree of caution should be considered in drawing conclusions when using the JSE with regard to these properties. It is recommended that future examinations of the JSE refer to the COSMIN guidelines to ensure complete and well-reported psychometric data are included.
Perplexity Method on the N-gram Language Model Based on Hadoop Framework

: The N-gram language model is used in statistical natural language processing like machine translation and speech recognition. The evaluation method of the N-gram probability needs a testing process. We use a distributed computing platform by using MapReduce algorithm and Hbase tables in Hadoop. Hadoop is an open source implementation of the MapReduce framework. The comparative query process is dependent on the NoSQL database. The NoSQL database is used to store the testing data sets in tables with different structures. The evaluation process uses a MapReduce algorithm on the testing process which acting as a decoder but distributed. This decoder can process multiple testing texts together. There are two ways to perform the MapReduce query on testing data. First one called forward query and the second is hiding query. We focus on the query response time on a single user runs of three different corpora in the N-gram model. The perplexity method is a correct way to estimate the performance of the language model. The perplexity of the testing set is compared with traditional language modeling package SRILM Toolkit. The result is discussed depending on the choice of the different Hbase tables. The results demonstrate that the proposed framework provide enhanced performance such less time cost, small memory size.
Replacing Soybean Meal with Urea in Diets for Heavy Fattening Lambs: Effects on Growth, Metabolic Profile and Meat Quality

Simple Summary There is a renewed interest on the potential inclusion of urea in ruminant diets, reducing the contribution of vegetable protein supplements. This study was designed to evaluate the effect of replacing soybean meal with different proportions of urea in protein-rich diets for heavy fattening lambs (from 29 to 50 kg of live body weight). Our results suggest that 39% of soybean meal of such diets can be replaced with urea reducing the feeding costs without any adverse effects on feed efficiency, rumen fermentation, or carcass and meat quality. Nevertheless, urea supplementation even at levels of 1% of dry matter may trigger mild metabolic acidosis that can affect animal health in the long term. Abstract Thirty-six Assaf male lambs (29.4 ± 3.10 kg body weight (BW)) were used to study the feasibility of including urea (at 0, 0.6 or 0.95% of dry matter for Control, Urea1, and Urea2 diets, respectively) in substitution of soybean meal in fattening diets. Animals were individually penned and feed intake was recorded daily. Blood samples were taken at days 35 and 63 of the experimental period to determine the acid-base status and the biochemical profile. At the end of the experiment (nine weeks), lambs were slaughtered, ruminal contents were collected and carcass and meat quality were evaluated. There were not differences (p > 0.05) among treatments in dry matter intake, animal performance, ruminal fermentation pattern, and carcass and meat parameters. Serum albumin concentration was higher and concentration of HCO3 and total CO2 in blood were lower in Urea2 compared to Urea1 and Control lambs. These results, together with the tendency to lower (p = 0.065) blood pH in this group might suggest a moderate metabolic acidosis. Partial replacement of soybean meal with urea did not impair growth rate in heavy fattening Assaf lambs (from 29 to 50 kg body weight), reduced feeding costs and had no adverse effects on feed efficiency, rumen fermentation and carcass and meat quality.
Power-velocity relationship and muscular strength in female volleyball players during preparatory period and competition season.

PURPOSE The aim of the study was to investigate changes of power-velocity relationship and muscular strength of female volleyball players during preparatory period and competition season. METHODS The study was conducted on eleven female volleyball players: age 21.6 ± 1.7 years, body height 177.9 ± 4.7 cm, body mass 71.3 ± 6.6 kg. Power-velocity relationship was determined by means of five maximal 10-second cycloergometer efforts with external loads equal to: 2.5, 5, 7.5, 10 and 12.5% of body weight (BW). The joint torque of flexors and extensors of an elbow, shoulder, hip, knee and trunk was measured using a torque meter. The measurement were taken before (I) and after (II) the preparatory period, after the first (III) and second (IV) competitive season. RESULTS The power with a load equal to 2.5, 5.0, 7.5, 10.0% BW increased significantly after first and second competitive season. The sums of joint torque for the lower and upper limb changed insignificantly. In the case of the right upper limb, sum of the joint torques was significantly reduced by 9.5% between measurement I and IV. Sum of the left upper limb was significantly decreased by 9.8% between measurement I and II. Sum of the joint torque of the trunk was significantly increased between measurements I and II, III and IV by 12.9%, 12.3% and 11.2%, respectively. CONCLUSION Obtained results may suggest that selection of the training loads was adequate for training power output and muscle strength of lower limbs but too little emphasis was placed on development of strength in the muscles of the upper limbs.
The effect of postpartum care at home on maternal received care and satisfaction

Background: One of the most important indicators of quality of services and monitoring health services is evaluation and assessment of patient satisfaction of services that comes from sociology research. Aim: To identify the effect of providing post partum care at home on maternal received care and satisfaction. Method: This clinical trial was carried out on 200 mothers who referred to Akbar Abad Health Care Center for their infant screening tests. They were randomly allocated to two experimental and control groups. Experimental group received their first and second post partum care at home, but control group only received routine postpartum care of the health center. Data were collected using a questionnaire containing demographic characteristics and some question to assess maternal received care and satisfaction with postpartum care. Chi square and T test were applied for analyzing data using SPSS version 18. P value less than 0.05 considered statistically significant. Results: Most of the mothers were 20-29 years old. Two groups were significantly different in relation to percentage of received care at the first and second post partum and infant care (P=0.00, P=0.01). The average score of emotional and educational services that mothers received and also maternal satisfaction were also significantly different between two groups (p=0.00). Conclusion: Postpartum care provided at home, has positive effect on maternal emotional and educational received care and also their satisfaction. So we suggest post partum health care provision by health care providers at home.
