Fine structure of spermatophores of some Oribatid mites (Acari, Arachnida)

The ultrastructure of spermatophores was studied in seven species of Oribatei. Each spermatophore is composed of a head and a stalk which is attached to the substratum. The spherical head consists of two distinct portions: (1) the sperm package; and (2) the head matrix. Position and structure of the sperm package are described in the different species, as well as the various structures in the head matrix. The sperm package contains sperm embedded in secretory products. The most characteristic feature of the sperm is an electron‐dense chromatin body. Mitochondria lie adjacent to it or are partly or completely incorporated into the chromatin body. The cytoplasmic surface of the plasma membrane regularly bears an electron‐dense layer; the plasma membrane is covered by a secretory sheath. The spermatophores of the Oribatei are structurally complicated and not uniform. The possible role of the spermatophore's structural elements is discussed and an attempt is made to evaluate characteristic features taxonomically.
Laypeople roles at road traffic crash scenes: a systematic review

Abstract This study aimed to identify the roles of laypeople at road traffic injuries (RTIs). A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The key words of ‘laypeople’, ‘layman’, ‘layperson’, ‘bystander’, ‘first responder’, ‘lay first responder’, ‘road traffic’, ‘road traffic injury’, ‘crash injury’, ‘crash scene’, ‘emergency’, ‘trauma care’, and ‘prehospital trauma care’ were used in combination with the Boolean operators OR and AND. We did electronic search on Google Scholar, PubMed, ISI Web of Science, CINAHL, Science Direct, Scopus, ProQuest. Based on the reviewed studies, some factors such as cultural conditions, knowledge, relief agencies, and demographic factors affect the interventions of laypeople at the crash scene in functional areas. Regarding the permanent presence of people at the crash scene, the present study can provide an opportunity to reduce different side effects of RTIs imposed on the society.
The Flow and Reuse of Data: Capabilities of AutomationML in the Production System Life Cycle

With the mega trend of digitalizing industry [1], several new application scenarios have arisen, such as order-controlled production, adaptable factories, self-organizing adaptive logistics, value-based services, and circular economies [2]. These scenarios address manufacturers' concerns, including increased individualization and the demand for shorter innovation cycles of their products. However, for the digitalization and enabling of the application scenarios, data are crucial. How are data generated, processed, stored, and exchanged? The flow and reuse of data need to be considered throughout the manufacturer's company. However, what data must be taken into account? According to Lu et al. [11], the three manufacturing dimensions (i.e., product, production system, and business) of a company should each be analyzed along its life cycle. This analysis includes the data generated, processed, stored, and exchanged within and across these dimensions. Each dimension and life-cycle phase involves different stakeholders, disciplines, and software tools that come with a different view of the product, production system, or business. This view is typically reflected by or within the data, i.e., how the data are structured (syntax) and what is meant by each data object (semantics). A way of unifying and standardizing the data is, therefore, required to enable the flow of information and data reuse, i.e., consistent data exchange.
Selecting digital children's books: an interview study

Introduction. The market for digital children's books is growing steadily. But the options vary in terms of quality and parents looking for suitable apps for young children can get overwhelmed quickly. This study seeks to answer how families search for suitable applications and what aspects are important to them while selecting. Method. Semi-structured interviews were conducted with eight families who have already gained experience in the use of digital children's books. The investigation focused on children aged one to seven years. Families were asked about specific approaches during the search for and the selection of appropriate media offerings. Analysis Different coding methods were applied for data analysis and analytical memos were used throughout the research process. Results. Search strategies and various selection criteria for selecting digital children's books could be identified. The analysis indicates that these criteria relate more to external characteristics and safety or privacy issues than to content-related features. Conclusions. While the statements of the parents interviewed for selecting printed children's books confirm the results of previous studies, their approaches for selecting digital children's books are significantly different. The interviews suggest that families are still insecure about the applications and their selection.
Innovation activity data processing and aggregation based on ontological modelling

Innovation capacity building plays a central role in the growth dynamics of successful developing countries. However, no dedicated studies on ontological modeling of economic processes related to innovative activity at macro level were found. The application of semantic web technologies enables a unified, flexible structure and integrates not only quantitative but, more importantly, qualitative indicators and creates conditions for machine processing in the future. This paper presents the rationale for the selected domain modeling method for the subsequent construction of automated search information system; the ontology for innovative activity and economic potential is developed in context of the RF macroeconomics. An approach and search algorithms for economic data sources and data collection were developed under this study and casting data to the ontology structure of innovative activity and economic potential was performed. The relevance and scientific novelty of the study is determined by the problem domain, as well as the application of semantic web technologies to data collection from distributed heterogeneous sources, including those semi-structured and unstructured.
Trends in corneal transplantation at the University Eye Hospital in Tübingen, Germany over the last 12 years: 2004 – 2015

Purpose This study aimed to investigate the trends in the surgical methods and leading indications for corneal transplantations carried out over the last 12 years. Methods The data from the corneal graft waiting list and from all keratoplasties carried out between 2004 and 2015 at the University Eye Hospital in Tübingen were retrospectively analyzed. Results A total of 1,185 keratoplasties were performed between 2004 and 2015 at this hospital. The most common surgical indications for corneal transplantation were Fuchs’ endothelial corneal dystrophy (35.2%) and keratoconus (18.9%) with keratoconus being the leading cause during early years (from 2004 to 2009) and Fuch’s dystrophy being the leading cause from 2010 to 2015. Overall, the total count of performed keratoplasties increased, from 385 corneal transplantations during the first 6-year period to 800 corneal transplantations during the second 6-year period (P = 0.008, using Mann-Whitney test). The Descemet’s membrane endothelial keratoplasty has become the favored surgical method for endothelial disorders with the number of Descemet’s membrane endothelial keratoplasties increasing significantly from 2008 to 2015. This increasing trend was statistically significant (P < 0.001 using multivariate adaptive regression splines (MARS). A decreasing trend was also noted for the rate of penetrating keratoplasty since 2008 (P < 0.001 using MARS). Conclusions This research showed major changes in the preferred corneal transplantation techniques and leading indications for keratoplasty over the last 12 years. More importantly, it seems that the rapid development and implementation of endothelial keratoplasty, especially the Descemet’s membrane endothelial keratoplasty, has had a profound effect on and begun a new era in corneal transplantation.
Interviewing Witnesses: Eliciting Coarse-Grain Information

Eyewitnesses to crimes sometimes report inaccurate fine-grain details but fail to report accessible and potentially accurate coarse-grain details. We asked college students and community members (aged 17 to 62 years) who viewed a video of a simulated crime to answer interviewers’ questions at coarse- and fine-grained levels of detail and measured the quantity and accuracy of their responses. Three experiments (overall N = 219) also (a) provided comparative data for participants who were interviewed using the open-ended Self-Administered Interview (Gabbert, Hope, & Fisher, 2009) or one of two “report everything” open-ended procedures, (b) tested the efficacy of the procedure using both written and verbal interviews, and (c) examined the generality of the findings across different encoding stimuli which required variations in the types of cued recall questions asked. Coarse-grain reporting seldom occurred under the free recall interview conditions. Witnesses provided abundant coarse-grain details when required to respond to probes about specific details (i.e., cued recall forced report conditions)—without obvious cost to overall accuracy relative to accuracy of similar detail reported under free recall conditions—regardless of whether they responded on a written questionnaire or in a face-to-face individual interview. These experiments suggest that a procedure that requires cued recall forced reporting of coarse-grain detail may offer potential in certain investigative situations as an adjunct to the widely recommended open-ended forensic interviewing techniques.
Validity of Heart Rate-Based Models for Estimating Oxygen Uptake During Tennis Play.

Baiget, E, Iglesias, X, and Rodríguez, FA. Validity of heart rate-based models for estimating oxygen uptake during tennis play. J Strength Cond Res XX(X): 000-000, 2018-This study aimed to assess the validity of an on-court tennis test (specific endurance tennis test [SET-Test]) and 2 heart rate (HR)-based methods for estimating oxygen uptake (V[Combining Dot Above]O2) in competitive tennis players. Thirty-five male players performed a SET-Test to relate test duration (minutes) and V[Combining Dot Above]O2. Two weeks later, 16 players performed a simulated match play set where HR and V[Combining Dot Above]O2 (V[Combining Dot Above]O2-PLAY, criterion value) were measured and then compared with V[Combining Dot Above]O2 values predicted from the HR/V[Combining Dot Above]O2 linear regression equations derived from the SET-Test (pV[Combining Dot Above]O2-TEST) and from the one set match play (pV[Combining Dot Above]O2-PLAY). Test duration and V[Combining Dot Above]O2-TEST were strongly correlated (r = 0.821, p < 0.001, SEE = 5.6 ml·kg·min), indicating that SET-Test outcome is a somewhat good indicator of aerobic fitness in tennis players, likely to be useful for training purposes. pV[Combining Dot Above]O2-PLAY and V[Combining Dot Above]O2-PLAY (criterion value) were strongly correlated (r = 0.832, p < 0.001) and SEE was moderate (3.5 ml·kg·min = 11.5%). pV[Combining Dot Above]O2-TEST differed from the criterion (32.4 ± 10.7 vs. 30.8 ± 8.6 ml·kg·min, p < 0.001) and, although strongly correlated (r = 0.689, p < 0.001), an overestimation occurred (mean Δ = 1.6 ml·kg·min = 4.9%), yielding a high SEE (4.8 ml·kg·min = 15.6%). We conclude that (a) SET-Test performance is a valid and moderately accurate predictor of V[Combining Dot Above]O2; and (b) the individual HR-V[Combining Dot Above]O2 regression equation generated during tennis match play predicts V[Combining Dot Above]O2 with greater accuracy than the regression derived from the SET-Test.
Exploring reward mechanisms on social question and answer Websites: quantifying the interdependences among user activities

Introduction. Previous studies suggest that the users of social question and answer Websites contribute their knowledge to a community in exchange for intrinsic rewards from other members, such as reciprocity and reputation. Thus, rewarding knowledge contributors is of great importance for maintaining the users of such Websites. However, there is a lack of knowledge on the reward mechanisms used by the sites. In addition, while previous studies have highlighted the importance of reciprocity in motivating knowledge sharing, little is known about how reciprocity takes place in a knowledge community, hence, this study addresses that research gap. Method. This study seeks to explore reward mechanisms and quantify the conversion ratio based on studying the profiles of 33,974 observations from a Chinese social question and answer Website. Analysis. The structural equation modelling technique was adopted to estimate the research model via the partial least squares approach. Results. The results show that users who have more followers and publish more questions and articles, tend to answer more questions on social question and answer Websites. The interaction effect between the users’ question-asking activities and the appreciation they receive has a significant influence on user popularity. Conclusions. Writing articles and providing answers generate appreciation from other community members. In addition, users are likely to follow individual users who not only asked interesting questions but who also provided high-quality answers, implying a likeminded effect.
The Unemployment Puzzle of Corporate Taxation

Using annual data on nineteen industrial countries for the period 1979–2005 and a large number of controls, this article is the first to empirically study the impact of corporate taxes on the unemployment rate. In contrast to previous empirical research on the labor demand, investment and growth effects of corporate taxation, which consistently finds adverse effects, the regression results suggest that higher corporate taxes may have a favorable impact, lowering the unemployment rate. The magnitude of the estimated effect is substantial. The results of this study are robust to both endogeneity and numerous variations in specification.
Contemporary Dietary Intake: Too Much Sodium, Not Enough Potassium, yet Sufficient Iodine: The SALMEX Cohort Results

Initiatives to reduce sodium intake are encouraged globally, yet there is concern about compromised iodine intake supplied through salt. The aim of the present study was to determine baseline sodium, potassium, and iodine intake in a sample of workers from our Institution in Mexico City (SALMEX Cohort). Methods. From a cohort of 1009 workers, appropriate 24-h urine and three-day dietary recall was collected in a sample of 727 adult subjects for assessment of urinary sodium, potassium, and iodine concentrations. Median urinary iodine excretion (UIE) was compared across categories of sodium intake of <2, 2–3.6, and ≥3.6 g/day. Results. Average sodium intake was 3.49 ± 1.38 g/day; higher in men than women (4.14 vs. 3.11 g/day, p ≤0.001). Only 10.6% of the population had sodium intake within the recommended range (<2 g/day); 45.4% had high (2–3.6 g/day) and 44% had excessive intake (>3.6 g/day). Average urinary Na/K ratio was 3.15 ± 1.22 (ideal < 1), higher in men (3.42 vs. 3.0, p ≤ 0.001). The multivariate analysis showed that sodium intake was associated with age (p = 0.03), male sex (p < 0.001), caloric intake (p = 0.002), UKE (p < 0.001) and BMI (p < 0.001). Median iodine intake was 286.7 µg/day (IQR 215–370 µg/day). Less than 2% of subjects had iodine intake lower than recommended for adults (95 µg/day); 1.3% of subjects in the recommended range of salt intake had low iodine intake. There is a direct relationship between iodine and sodium urinary excretion (r = 0.57, p < 0.0001). Conclusions. In the studied population, there was an excessive sodium intake and an imbalance between sodium and potassium intake. Only 10.6% of the population had sodium intake within the recommended values, but iodine intake in this group appears to be adequate.
Intensity Specific Repetitive Mild Traumatic Brain Injury Evokes an Exacerbated Burden of Neocortical Axonal Injury

Mild traumatic brain injury (mTBI) has been linked to enduring neurological damage following repetitive injury. Previously, we reported that intensity-specific, repetitive mTBI exacerbated microvascular and axonal damage in brainstem. For a more rigorous and global assessment, we assessed the burden of neocortical diffuse axonal injury (DAI) evoked by repetitive mTBI. Mice were subjected to mild central fluid percussion injuries at 1.4 and 1.6 atm with or without repetitive insult at a 3-hour interval and killed at 24 hours postinjury. Neocortical DAI within layer V was quantitatively assessed by double-labeling p-c-Jun and NeuN to identify both the axotomized and total neuronal population. Both confocal and electron microscopic findings revealed no apparent evidence of neuronal death. Repetitive mTBI of 1.6 atm group, but not of 1.4 atm group, demonstrated a significantly higher proportion of axotomized neurons. These results demonstrate that different intensities of mTBI induced different burdens of DAI after repetitive insult. Interestingly, the parallel loss of the righting reflex reflected differences in injury intensity, yet the duration of this reflex was not elongated by the repetitive insult. These data highlight some of the complex issues surrounding repetitive mTBI and its associated morbidity, mandating the need for continued exploration.
Multi-dimensional Connectionist Classification: Reading Text in One Step

Offline handwriting recognition systems often use LSTM networks, trained with line- or word-images. Multi-line text makes it necessary to use segmentation to explicitly obtain these images. Skewed, curved, overlapping, incorrectly written text, or noise can lead to errors during segmentation of multi-line text and reduces the overall recognition capacity of the system. Last year has seen the introduction of deep learning methods capable of segmentation-free recognition of whole paragraphs. Our method uses Conditional Random Fields to represent text and align it with the network output to calculate a loss function for training. Experiments are promising and show that the technique is capable of training a LSTM multi-line text recognition system.
Impact of the Familiar Environment in 11–14-Year-Old Minors’ Mental Health

The analysis of the mental health in children under 14 years has become a research topic of global interest where the family can be a key factor for protection or risk against mental health problems. With this work, we intend to determine, employing binary logistic regression analysis, whether parental acceptance-rejection perceived by boys and girls can predict their mental health. Seven hundred sixty-two students participated, the average age was 12.23 years; 53.8% (n = 410) girls and 46.2% (n = 352) boys. We have used the Strengths and Difficulties Questionnaire (SDQ), self-reported version and the Affection Scale children version (EA-H) for parental acceptance-rejection to assess mental health. The odds ratio (OR) of the logistic models reports that there is a greater probability of having mental health problems in boys and girls when they perceive that they are highly criticized and rejected by their parents. With our work, we highlight the importance of the environment and family affection on mental health. The perception of the children about the rejection, aversion, and criticism of their parents constitutes a risk factor in the manifestation of mental health problems.
Renalase is associated with adverse left atrial remodelling and disease burden in patients with atrial fibrillation undergoing pulmonary vein isolation.

BACKGROUND Renalase is a catecholamine-metabolising enzyme, but its possible association with atrial fibrillation (AF) remains unknown. AIM We sought to evaluate plasma renalase concentration in patients with AF undergoing pulmonary vein isolation (PVI) with respect to AF clinical characteristics, left atrial (LA) remodelling, and PVI efficacy. METHODS This case-control study included 69 patients (median age 58 years) with either paroxysmal (89%) or persistent (11%) AF, referred for PVI, and a control group consisting of 15 patients without AF, matched for age, sex, and comorbidi-ties. An evaluation of transthoracic echocardiography with LA speckle tracking and plasma renalase concentration using an enzyme-linked immunosorbent assay was performed. AF recurrence was defined as any AF episode on seven-day electro-cardiographic monitoring at six-month follow-up. RESULTS Renalase level was higher in the study group than in the control group (mean 27.99 vs. 21.48 μg/mL, p = 0.004), but it was lower in patients with persistent AF (19.05 vs. 28.77 μg/mL; p = 0.023) and among patients with AF episodes di-rectly preceding PVI (24.50 vs. 29.66 μg/mL; p = 0.04). Renalase concentration within the first quartile was associated with higher mean heart rate (70 vs. 61 bpm, p = 0.029), greater AF burden (36.9% vs. 9.3%, p = 0.027), greater LA diameter (41.1 vs. 37.9 mm, p = 0.011), and a trend towards less negative global LA strain (-9.4 vs. -13.5, p = 0.082). Logistic regres-sion revealed that global four-chamber LA strain was the only independent predictor of renalase variability (p = 0.0045). Renalase concentration did not predict AF recurrence at six-month follow-up (area under curve [AUC] = 0.614, p = 0.216). CONCLUSIONS Low renalase level may be associated with impaired rate control, higher AF burden, and advanced LA remodel-ling in AF patients undergoing PVI, but it does not predict sinus rhythm maintenance.
What Has Bariatric Surgery Taught Us About the Role of the Upper Gastrointestinal Tract in the Regulation of Postprandial Glucose Metabolism?

The interaction between the upper gastrointestinal tract and the endocrine system is important in the regulation of metabolism and of weight. The gastrointestinal tract has a heterogeneous cellular content and comprises a variety of cells that elaborate paracrine and endocrine mediators that collectively form the entero-endocrine system. The advent of therapy that utilizes these pathways as well as the association of bariatric surgery with diabetes remission has (re-)kindled interest in the role of the gastrointestinal tract in glucose homeostasis. In this review, we will use the changes wrought by bariatric surgery to provide insights into the various gut–pancreas interactions that maintain weight, regulate satiety, and limit glucose excursions after meal ingestion.
