Interpregnancy interval and pregnancy loss in a rural South Africa : A population-based 1 cohort study 2 3 Running title : Interpregnancy interval & pregnancy loss

20 21 Study question: What is the relationship between interpregnancy interval (IPI) and 22 pregnancy loss in a a rural sub-Saharan African (SSA) setting? 23 Summary answer: IPIs >60 months, but not <6 months, were associated with a higher odds 24 of pregnancy loss in our SSA setting. 25 What is known already: IPIs >60 months are detrimental to both fetal and maternal health, 26 while contradictory findings exist for IPIs <6 months. No studies have investigated the 27 relationship between IPI and pregnancy loss in SSA settings, despite high pregnancy loss 28 rates and exponential population growth in the SSA region. 29 Study design, size, duration: Population-based cohort involving 8940 women aged 16-35 30 years who reported two consecutive singleton pregnancies between 2000 and 2017. 31 Participants/materials, setting, methods: Study participants were from the uMkhanyakude 32 District in KwaZulu-Natal, South Africa. We obtained data on pregnancy-related 33 characteristics and other variables relevant to pregnancy loss from regular surveys conducted 34 by the Africa Health Research Institute (AHRI) as part of its demographic and health 35 surveillance platform. IPI was determined as the time in months between the end of the first 36 pregnancy and the start of the second pregnancy. Pregnancy loss was defined as either 37 miscarriage or stillbirth. We used an adjusted logistic regression model to investigate the 38 relationship between IPI and pregnancy loss. 39 Main results and the role of chance: IPIs >60 months were associated with an almost three40 fold higher odds of pregnancy loss (Adjusted Odds Ratio: 2.64, 95% Confidence 41 Interval:1.71-4.09) when compared with IPIs of 6-60 months. IPIs <6 months conferred a 42 similar odds of pregnancy loss when compared with IPIs of 6-60 months (Adjusted Odds 43 Ratio: 0.82, 95% Confidence Interval: 0.35-1.91). 44 .

Stress and crack prediction during drying of Japanese noodle (udon)

Summary The distribution of stress during drying of fresh Japanese noodle (udon) was investigated by mathematically modelling the changes in shrinkage and other mechanical properties, this allowed crack formation to be predicted. It was observed that the shrinkage coefficients were nearly the same in all three directions with changing moisture content, and the degree of shrinkage was independent of the temperature. The Young's modulus, yield stress and fracture stress could be expressed as exponential functions of moisture content. Changes in stress distribution during drying were calculated by coupling the moisture transfer equation with the constitutive equation using a finite element method. The calculated stress distribution indicated that a rapid drying rate causes extensive internal tensile stress in udon. The scheme used in the present study was found to effectively represent the potential for crack formation along the central axis, this was shown to be consistent with the actual cracking pattern.
Analytical Tools for the Characterization of Power Devices

Since power devices require an electrically active, thick n-type silicon layer with high resistivity and a large area, their electrical characteristics are extremely sensitive to contamination. If transition metals diffuse into the wafers during the high temperature steps required for device fabrication, an uncontrolled increase in leakage current and on state voltage can be observed. Furthermore, current filamentation and instabilities of the electrical data can occur. As a consequence of the low doping level of the n-base, the blocking voltage and the failure rate due to cosmic radiation are sensitive to contaminating atoms acting as donors or acceptors. To obtain information about the sources and the extent of the contamination, a contamination check was performed after each high temperature step. Moreover, the dependence of the carrier lifetime on temperature and injection level was analyzed for typical operation conditions of power devices. The results proved to be important in finding ways of keeping contamination and silicon defect densities as low as possible and to ensure that good electrical data with adequate stability could be obtained.
Examining Users’ Willingness to Post Sensitive Personal Data on Social Media

Reaping the vast benefits of ubiquitous social media requires users to share their information, preferences, and interests on these websites. This research draws on communications privacy management theory and the online privacy literature to develop and validate an empirical research model testing users’ willingness to share sensitive data on Facebook. The data were collected using an online survey from 569 respondents, however; 515 responses were valid for the statistical analysis. The valid data were analyzed using SMARTPLS2. The findings showed the need for attention as a significant predictor of Facebook users’ willingness. Neither individual perceptions of privacy control nor privacy risks had an impact on the variable of interest. Furthermore, the evidence supported the positive impact of each of deposition to value privacy and the perceived effectiveness of Facebook’s privacy policy on mitigating Facebook users’ perceptions of the risks of posting their private data on the website. The paper discusses the study’s theoretical and managerial implications along with its limitations.

Myocarditis is an inflammatory disease of the myocardium, with heterogeneous etiology. Although rare, myocarditis can be a complication of the influenza infection. In the majority of cases, viral myocarditis is a self-limiting infection passing without permanent changes in the myocardium. We present a clinical case of a 30-year-old woman with acute heart failure in the course of respiratory infection accompanied by severe systolic dysfunction [left ventricular (LV) ejection fraction (EF) 19%]. The patient was treated according to the current guideline recommendations for the treatment of acute and chronic heart failure with the conjunction of immunostimulating and metabolic therapy. During hospitalization from microbial and viral testing, acute-phase antibodies to parainfluenza virus were identified. Following the treatment, a complete resolution of heart failure symptoms and restoration of LVEF to baseline (40%) was observed. Timely initiation of treatment in myocarditis, followed by good clinical course and regression of LV systolic dysfunction, in some cases may cancel invasive procedures such as endomyocardial biopsy.
Mining Sports Articles using Cuckoo Search and Tabu Search with SMOTE Preprocessing Technique

Sentiment analysis is one of the most popular domains for natural language text classification, crucial for improving information extraction. However, massive data availability is one of the biggest problems for opinion mining due to accuracy considerations. Selecting high discriminative features from an opinion mining database is still an ongoing research topic. This study presents a two-stage heuristic feature selection method to classify sports articles using Tabu search and Cuckoo search via Levy flight. Levy flight is used to prevent the solution from being trapped at local optima. Comparative results on a benchmark dataset prove that our method shows significant improvements in the overall accuracy from 82.6% up to 89.5%.
Preliminary assessment of the genetic diversity of Ecuadorian Ilex guayusa using inter simple sequence repeat (ISSR) markers

We assessed the degree of genetic diversity of llex guayusa, a species of ethnobotanic and commercial relevance for indigenous communities of the Ecuadorian Amazon. We characterized 157 individuals, from small cultivation sites across six provinces, using nine Inter Simple Sequence Repeat (ISSR) markers. A total of 91 polymorphic bands were detected in, but estimated heterozygosity (He = 0.19) revealed a reduced level of genetic variability. Pairwise-Nei genetic distance indices (0.013 ≤ Ds ≤ 0.086) implied a reduced level of genetic divergence between individuals from different provinces. Accordingly, partitioning of genetic diversity (AMOVA) indicated that only 18% of variation observed for I. guayusa occurred between populations. The low degree of genetic diversity found for I. guayusa could be ascribed to the fact that the species is exclusively cultivated via clonal propagation; a cultural activity which has probably homogenized the species' genetic pool across its geographic range of cultivation. However, PCoA analysis resolved collected germplasm into three distinct groups displaying a subtle genetic contrast in a directional gradient, from north to south. The inclusion of a higher number of samples from underrepresented provinces (i.e. Sucumbíos), and wild populations, if they exist, would help resolve knowledge gaps regarding the genetic diversity and population structure of the species and its cultivation history in the region.
Efficient Fluorescence detection of Fe3+, Cd2+ based on an azine-Functionalized Zn-Metal-Organic Framework

The design and synthesis of sensitive and selective luminescent materials as chemical sensing agents is a fundamental goal in fluorescence assays. Considering high porosity, large surface area, excellent photoluminescence property of metal-organic frameworks (MOFs), luminescent properties of a microporous azine-functionalized MOF, TMU-16, dispersed in different metal ions have been investigated systematically. The TMU-16 displays superb luminescence emission, and it can detect Fe(III) and Cd(II) ions with high selectivity, excellent sensitivity, and short response time (<1 min). The emission intensities of TMU-16 were quenched upon the addition of Fe(III) and increased upon the addition of Cd(II). The effect of other metal ions on the fluorescence intensity of the MOF was also studied and other metal ions showed low interference response in recognition of Fe(III) and Cd(II). More importantly, this is the first example of MOF-based luminescent sensor as efficient multifunctional fluorescence material which can use for selective sensing of Fe(III) and Cd(II) ions.
Effect of Marketing through Value Added and Video Sales on Feeder Cattle Prices

Feeder cattle marketing opportunities for producers in Missouri continue to expand. Missouri ranks within the top ten U.S. States in beef cow inventory and is a major feeder calf exporter. Selecting the appropriate marketing opportunity can have a dramatic impact on the income of the cattle producer. Feeder cattle marketing opportunities include value-added program sales, video auctions, as well as the traditional live cattle auction. A long-term study comparing these marketing opportunities in a single livestock market in Missouri has not been conducted. The objective of this study is to analyze cattle characteristics that can influence market price in feeder cattle auctions and quantify any price premiums received for video or value-added over traditional sales. Data for this study was collected between March 2009 and December 2018 at Joplin Regional Stockyards, near Carthage, Missouri. Although cattle were sold through the same livestock auction different marketing strategies including value-added, video, or traditional feeder cattle auction were utilized. Market data from value-added, video, and traditional feeder sales over the study period included 521,586 lots encompassing 3,400,621 head of cattle. Analyzed descriptive factors that could affect the sale price of marketed cattle included sale date, weight class of lot, number of cattle per lot, gender, color/ breed influence, and auction type. Descriptive statistical analysis in Minitab 19 (Minitab Inc., State College, PA) was used to identify trends in the data. Multilinear regression analysis in Minitab 19 (Minitab Inc., State College, PA) was used to analyze the significance of categorical variables on the bid price. Analyzed categorical factors were found to be significant (P < 0.05). Overall value-added and video sales earned mean price premiums of $1 per cwt and $5.36 per cwt respectively in comparison to traditional auctions. This study confirms along with previous research that over time cattle sold through value-added and video sales will consistently sell for higher mean bid prices when compared to cattle at traditional auctions. Producers that take part in value-added management and marketing opportunities are likely to receive a higher price for their cattle than those sold through traditional auctions.
Smart Cities in India: Practices, Policies, Current Status and Gaps

The concept of smart cities is growing across various countries of the world as the population continues to grow. As a developing country, India has also taken up the initiative to develop and promote the smart city culture in the country. The smart city mission developed by the government was the first step towards this initiative. The mission promised to create and develop smart cities in the country that would make stand among the countries that are a part of this program. This research tracks the smart city mission that was launched by the Indian government along with the plans and policies put forth by the authorities. The issues that hinder the growth of the mission have been discussed. The various gaps that existed and slowed down the growth of this mission have also been identified.
High-Precision and Low-Complexity Approximate Homomorphic Encryption by Error Variance Minimization

In this paper, we propose a high-precision and low-complexity Cheon-Kim-Kim-Song (CKKS) scheme (Asiacrypt ’17) by reducing error and improving its bootstrapping through error variance minimization. The proposed algorithm allows us to leave more levels after bootstrapping, and thus, with practical accuracy, we reduce the degree of ciphertext polynomial of the CKKS scheme from 2 16 to 2 15 . The sizes of the key and ciphertext are reduced by at least 1/4, which signiﬁcantly reduces their computational complexity. Those are possible from the fact that a smaller scaling factor can be used with the proposed algorithms for the same precision since the following two contributions signiﬁcantly reduce the error of the CKKS scheme, especially in bootstrapping. First, we apply the concept of signal-to-noise ratio (SNR) and propose a method of maximizing the SNR of encrypted data by reordering homomorphic operations. For that, the error variance is minimized instead of the upper bound of error when we deal with encrypted data. Especially, we propose lazy rescaling and lazy relinearization, which reduces computational complexity as well as error variance. Second, we propose a novel polynomial approximation specialized for the CKKS scheme from the same perspective of minimizing the error variance of the encrypted data. We mainly apply the approximation to the bootstrapping of the CKKS scheme, where we achieve a smaller bootstrap error compared to the prior arts. The performance improvement of the proposed algorithms for the CKKS scheme is veriﬁed by implementation over a well-known homomorphic encryption library, SEAL. Speciﬁcally, for very accurate bootstrapping, the proposed method achieves the same bootstrap error with only a depth of 8, whereas it requires a depth of 13 in the prior art.
Differences in Perception Between Students and Teachers of High School Science: Implications for Evaluations of Teaching and Classroom Evaluation.

The science teacher in the modern high school acts as the designer and driver of the in-class practice. In this role, the teacher must broadly assess the effect of the practice on the student. This would rely on accurate self-knowledge of how they act in class and impact their students. In this study we explore these issues by comparing the difference in responses of 86 teachers and 2512 Year 9 and 10 students to an instrument probing their perceptions of their in-class practice. We report two significant findings. First, not only do teachers constantly positively overrate their in-class practice but secondly, these perceptions are completely unrelated to how their students see their classrooms. This implies that using teachers as the sole source of evaluation about their own classroom practice is problematic and that evaluation should always be endeavoured to be undertaken at the level of both teachers and students.
Recent trends in tropospheric NO2 over India observed by SCIAMACHY: Identification of hot spots

Satellite remote sensing technology has a great potential to measure the properties of atmosphere and has shown marked advancements through the last decade, in monitoring nitrogen oxide species (NOX) in troposphere. NO2 in troposphere is one of the key factors which determine the air quality and has serious implications on human health and plant growth. It is also well known for its indirect contribution to climate change. The identification of spatial and temporal variations of NO2 is necessary for any effective mitigation plan to curb its obnoxious abundance. Tropospheric NO2 measurements provided by the satellite remote sensor “SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY” (SCIAMACHY) are utilized here to identify the regions across India where a concentration of NO2 exceeds the permissible healthy level. A new approach based on empirical approximation is attempted to normalize the unit of satellite measurement with the unit of existing air quality standard. Trend analysis for all the regions are carried out by means of a non–linear regression method. The geospatial and statistical analysis of monthly tropospheric NO2 data from the full operational period of SCIAMACHY (2002 August–2012 March) have resulted in the identification of 12 hot spot regions across India among which most of them exhibited a significant increasing trend. Some of the rural districts which were not previously implicated for NO2 pollution risk are also recognized here. This study illustrates the possibility of the use of satellite measurements in air quality monitoring and management in regional spatial scale. The effects of seasonal climatic changes in India on the ambient NO2 pollution level are also explained.
Β Flank sucking in a Doberman pincher

Flank sucking is a behavioural abnormality of compulsive nature that occurs almost exclusively in Dober­ man pinchers and is frequently accompanied by other abnormal behaviours, such as aerai lick dermatitis, blanket sucking and pica. A 2.5-year old, intact male, Doberman pinscher was presented because of a two-month long history of persistent right flank sucking. The dog was up-to-date with vaccinations and lived exclusively outdoors with his mother. The onset of the problem coincided with a period of crate restraining, where a short chain was used to avoid copulation with his mother, when she was in oestrus. Since then, the abnormal behaviour occurred on a daily basis and was not associated with neuro­ logical signs. In addition, the dog presented blanket sucking and pica that had first appeared during puppy hood. No clinical abnormalities were detected and the dog did not show signs of anxiety, aggression or fear during physical examination and blood sampling. Later-on and while remaining calm in the waiting room of the Clinic, the dog started chasing, chewing and sucking his right flank for over three minutes, but stopped immediately after his owner's verbal intervention. Primary diagnosis was compulsive flank sucking; differential diagnosis included Trichuris vulpis infestation, allergic dermatitis and psychomotor seizures. Results of haematological and serum biochemical examinations were unremarkable, whereas serological examination for Leishmania and faecal parasitological examination did not reveal significant results. Suggested treatment included administration of an anthelminthic combination (praziquantel, pyrantel and febantel), orally, for 4 con­ secutive days and clomipramine, at the dose of 1 mg/kg of body weight, every 12 hours, orally, for a long period of time, along with instructions to avoid the causative and triggering factors. Two months later, the owner reported that, although clomipramine had not been administered, the abnormal behaviour disappeared when the dog had been relocated to a new environment with no other animals and was free to roam. However, flank sucking reappeared after the dog had been moved back to the initial environment and chained.
Solut on Set of 2 and 3-D mens onal Lyapunov Equat ons

In this study, a necessary and sufficient condition is given for the stability of the convex combinations of n-dimensional two Hurwitz stable matrices. There is a close relationship between Hurwitz stability of the matrix segment and common solution to the Lyapunov equations corresponding to those matrices. Therefore, the results obtained in this area are important. In the case of existence, an algorithm that determines common solutions set is also given. A number of illustrative examples using this algorithm are given.
Honesty in the city

Lab evidence on trust games involves more cooperation than conventional economic theory predicts. We explore whether this pattern extends to a field setting where (much like in a lab) we are able to control for (lack of) repeat-play and reputation: cab drivers in Mexico City. We find a remarkably high degree of trustworthiness, also with price-haggling, which is predicted to reduce trustworthiness.
Microsoft Word-numero_49_art_57_2414

This work is devoted to the application of the micromechanical Gurson-Tvergaard-Needleman (GTN) model to study the ductile tearing of 12NiCr6 steel. GTN model is widely used to describe the three stages of ductile tearing: nucleation, growth and the coalescence of micro-voids. A new approach based on the identification of the GTN damage model coupled or not with hardening laws using inverse analysis. After identification, the obtained results show a good agreement between the experimental curve tensile test of an axisymetric notched bar (AN2) and those numerically obtained for GTN model coupled with the hardening laws. In order to validate the identified GTN parameters, a simulation of tear test is conducted on 12 NiCr6 steel CT specimen. The numerical results are compared with experimental results found in the literature and a good agreement is obtained. This identification procedure is more accurate than when the damage parameters are identified independently of the hardening laws.
Simultaneous determination, by hydride generation and inductively coupled plasma atomic emission spectrometry, of arsenic, antimony, selenium and tellurium in silicate rocks containing the noble metals and in sulphide ores

A method is described for the continuous generation of the hydrides of arsenic, antimony, selenium and tellurium and the simultaneous determination of these elements by an atomic emission spectrometer with a 5-kW nitrogen-argon inductively coupled plasma source. After digestion of the sample, the analytes are separated from the matrix by coprecipitation with iron(III) hydroxide at pH 2.40. A standard additions technique is used for quantification. This method is relatively free from interferences and is applied to the determination of arsenic, antimony, selenium and tellurium in silicate rocks containing gold and the platinum-group metals (noble metals), and also in sulphide ores rich in transition metals and lead.
