Authors: Chauhan Alex , Pandey Nilesh , Raithatha Nitin , Patel Purvi , Desai Ajesh , Jain Neeraj 
Published: May 2018

Background: Toll-like receptor 9 (TLR9) plays a key role in the elimination of viral pathogens by recognising their CpG DNA. Polymorphisms in the TLR9 gene may influence their recognition and subsequent elimination. Therefore, the present study was designed to elucidate the role of a rare unexplored TLR9 gene polymorphism C296T/ Pro99Leu (rs5743844) in cervical cancer susceptibility among Indian women. Methods: The genotyping of TLR9 Pro99Leu polymorphism in 110 cervical cancer patients and 141 healthy controls was performed by polymerase chain reaction–restriction fragment length polymorphism (PCR-RFLP). Results: The genotype frequency detected in both cervical cancer and control populations was 1.0 (CC), 0.0 (CT) and 0.0 (TT); while the allele frequency was found to be 1.0 (C) and 0.0 (T). Conclusions: The present study results demonstrate no involvement of TLR9 C296T/ Pro99Leu polymorphism in cervical cancer susceptibility and supports worldwide minor allele frequency (MAF) (0.0002) status of the same as no nucleotide variation was detected in any of the study participants.

Published: May 2018

Background: Sexual partner concurrency has been implicated in the genesis of generalized HIV epidemic in South Africa. Most South Africans, however, disapprove of concurrency in surveys. These surveys test individuals’ explicit attitudes which are susceptible to a number of important biases such as the social desirability bias. Assessment of implicit cognitions have been found to be better predictors of behaviour in socially sensitive domains. We hypothesized that South Africans may have implicit attitudes more tolerant of concurrency than lower concurrency prevalence populations. Methods: To test this hypothesis, we developed a concurrency-implicit association test (C-IAT) and compared the C-IATs of samples of South African and Belgian university students. Results: We found a large and statistically significant difference in the C-IAT between the South Africans (D600-score = -0.009, indicating absence of preference for concurrency or monogamy) and Belgians (D600-score = 0.783, indicating a strong preference for monogamy; t-test = 13.3; P < 0.0001). The effect size measure, Cohen’s d, was found to be 0.88, which is considered a large effect size in this field. Conclusions: Our results are compatible with the thesis that differences in implicit attitudes to concurrency play a role in the genesis of generalised HIV epidemics.

Published: May 2018

Objectives The primary aim of this study was to assess the reproducibility of the recalled preoperative Oxford Hip Score (OHS) and Oxford Knee Score (OKS) one year following arthroplasty for a cohort of patients. The secondary aim was to assess the reliability of a patient’s recollection of their own preoperative OHS and OKS one year following surgery. Methods A total of 335 patients (mean age 72.5; 22 to 92; 53.7% female) undergoing total hip arthroplasty (n = 178) and total knee arthroplasty (n = 157) were prospectively assessed. Patients undergoing hip and knee arthroplasty completed an OHS or OKS, respectively, preoperatively and were asked to recall their preoperative condition while completing the same score one year after surgery. Results A mean difference of 0.04 points (95% confidence intervals (CI) -15.64 to 15.72, p = 0.97) between the actual and the recalled OHS was observed. The mean difference in the OKS was 1.59 points (95% CI -11.57 to 14.75, p = 0.10). There was excellent reliability for the ‘average measures’ intra-class correlation for both the OHS (r = 0.802) and the OKS (r = 0.772). However, this reliability was diminished for the individuals OHS (r = 0.670) and OKS (r = 0.629) using single measures intra-class correlation. Bland–Altman plots demonstrated wide variation in the individual patient’s ability to recall their preoperative score (95% CI ± 16 for OHS, 95% CI ± 13 for OKS). Conclusion Prospective preoperative collection of OHS and OKS remains the benchmark. Using recalled scores one year following hip and knee arthroplasty is an alternative when used to assess a cohort of patients. However, the recall of an individual patient’s preoperative score should not be relied upon due to the diminished reliability and wide CI. Cite this article: T. F. M. Yeoman, N. D. Clement, D.

Adaptive, variable resolution grids for bathymetric applications using a quadtree approach
Authors: Toodesh Reenu , Verhagen Sandra 
Published: May 2018

Abstract
The spatial sampling often used to process and represent bathymetric data are of fixed grid resolution where the least depth value is stored in each grid cell. This results in Digital Elevation Models (DEMs) that are used to depict the underlying features of the seafloor. With the discretion of the user, the resulting DEMs used may either be of coarse resolution or a very fine resolution surface which provides as many details as possible. However, depending on the resolution of the data collected and the variability of the seafloor, the arbitrary user defined grid resolution is not the best option. Hence we address the problem of finding an optimal grid resolution for representing and processing the bathymetric data for the application of bathymetric risk assessment whilst maintaining computational efficiency. Here we adopt the quadtree decomposition approach.
In addition, the research suggests the optimal criteria and standard deviation threshold,

σ

t
h

{\sigma _{th}}

values for this particular application. These suggestions are still flexible and can be optimized for this application depending on the end user requirements. Previous studies have focused only on the splitting criteria or the constrained criteria to ensure that there is homogeneous accuracy over the entire dataset. However, an investigation into the threshold selection for the standard deviation,

σ

t
h

{\sigma _{th}}

which describes the variability in the dataset is one of the most important splitting criterion, that is still lacking. Also, a new approach to store the depths in the grid in a time ordered approach for each epoch is shown.
By optimizing the criteria for the quadtree decomposition and time series algorithm, the approaches shown in this paper provide the adaptive, accurate DEM which makes optimal use of the available bathymetric data for the Netherlands Continental Shelf (NCS) as the study area. This data preparation step forms the basis for developing a probabilistic approach to assigning hydrographic resurvey frequencies in the NCS.
Synchronization Analysis of Inertial Memristive Neural Networks with Time-Varying Delays
Authors: Wei Ruoyu , Cao Jinde 
Published: May 2018

Abstract
This paper investigates the global exponential synchronization and quasi-synchronization of inertial memristive neural networks with time-varying delays. By using a variable transmission, the original second-order system can be transformed into first-order differential system. Then, two types of drive-response systems of inertial memristive neural networks are studied, one is the system with parameter mismatch, the other is the system with matched parameters. By constructing Lyapunov functional and designing feedback controllers, several sufficient conditions are derived respectively for the synchronization of these two types of drive-response systems. Finally, corresponding simulation results are given to show the effectiveness of the proposed method derived in this paper.

AbstractThe adjacency matrix of a graph is a matrix which represents adjacent relation between the vertices of the graph. Its minimum eigenvalue is defined as the least eigenvalue of the graph. Let Gnbe the set of the graphs of order n, whose complements are connected and have pendent paths. This paper investigates the least eigenvalue of the graphs and characterizes the unique graph which has the minimum least eigenvalue in Gn.
Translocal Communities – Exploring Mobility and Migration in Sedentary Societies of the European Neolithic and Early Bronze Age
Authors: Furholt Martin 
Published: May 2018

Zusammenfassung:
Mobilität und Migration sind seit einiger Zeit wieder verstärkt in den Mittelpunkt archäologischer Diskussionen gerückt. In diesem Aufsatz werden die Konsequenzen der neuesten molekularbiologischen Forschung für unser Verständnis neolithischer Gesellschaften untersucht. Als Ausgangspunkt dient dabei eine Kritik des Konzepts der Geschlossenheit und Kohärenz, die im modernen Denken verhaftet ist und unsere Vorstellungen von sozialen Einheiten bestimmt, etwa Siedlungsgemeinschaften oder Kulturen. Ebenso bestimmt diese Prämisse unsere Auffassung von sozialen Phänomenen, wie der Migration, die infolgedessen als klar umrissenes, einfach zu beschreibendes Phänomen aufgefasst wird. Solch eine unrealistische Prämisse behindert grundlegend unsere Versuche, vom archäologischen Material ausgehend soziale Organisation und Phänomene von Mobilität und Migration zu verstehen. Daher wird für eine alternative Sichtweise auf prähistorische soziale Organisation geworben und eine neue Herangehensweise an das Verhältnis zwischen den Verbreitungsmustern der materiellen Kultur im archäologischen Befund und der räumlichen Dimension sozialer Organisation vorgeschlagen. Ausgehend von einer handlungstheoretischen Sichtweise auf die Herstellung und Verbreitung materieller Kultur werden zwei Thesen entwickelt: 1) Die soziale Zusammensetzung neolithischer und frühbronzezeitlicher Gemeinschaften ist grundsätzlich eher als heterogen und fluktuierend, denn als homogen und stabil zu betrachten, und 2) im Gegensatz zum gängigen Denkmuster verweist eine besonders hohe Einheitlichkeit materieller Kultur in einer Region (wie sie ja meist als Grundlage der Definition archäologischer Kulturen dient) auf eine besonders hohe soziale Heterogenität in den lokalen Siedlungsgemeinschaften. Anstatt archäologische Kulturen zu reifizieren und ihre regionale Homogenität als Anzeiger sozialer Homogenität aufzufassen, wird also vorgeschlagen, dass ein höheres Maß an Homogenität materieller Kultur in einer Region hauptsächlich als Ausdruck einer erhöhten Zirkulation von Individuen im Raum und zwischen Siedlungsgemeinschaften zu verstehen ist, die vor Ort soziale Heterogenität erzeugt. Diese generelle Hypothese wird durch eine Diskussion der archäologischen und naturwissenschaftlichen Evidenz untermauert. Schließlich wird aber unterhalb dieser übergreifenden Perspektive dafür argumentiert, die im Einzelfall wahrscheinlich sehr unterschiedlichen Ausprägungen solcher sozialer Mobilitätsphänomene mithilfe der reichen sozialanthropologischen Literatur zu Migration und Mobilität und ihren sozialen Konsequenzen genauer zu untersuchen.
Conception du corpus et méthodologie d’analyse : Pour un renouvellement de l’analyse des discours institutionnels et politiques

Published: May 2018

Résumé
Nous posons dans cet article la question des frontières ou des limites que doivent ou ne doivent pas avoir les corpus textuels. Nous considérons que cette question est directement liée à l’objectif assigné à la recherche ainsi qu’à l’ancrage théorique, et qu’il n’y a donc pas une seule et unique méthode de constitution de corpus. Cette méthode de constitution n’est pas liée ici aux formats de constitution de corpus, et aux standards à adopter (TEI par exemple), mais plutôt aux aspects philologiques et herméneutiques qui président aux choix des données, et aux principes qui contribuent à regrouper dans un même corpus tel ou tel type de texte.
On the Dynamical Nature of Nonlinear Coupling of Logarithmic Quantum Wave Equation, Everett-Hirschman Entropy and Temperature
Authors: Zloshchastiev Konstantin G. 
Published: May 2018

Abstract
We study the dynamical behavior of the nonlinear coupling of a logarithmic quantum wave equation. Using the statistical mechanical arguments for a large class of many-body systems, this coupling is shown to be related to temperature, which is a thermodynamic conjugate to the Everett-Hirschman’s quantum information entropy. A combined quantum-mechanical and field-theoretical model is proposed, which leads to a logarithmic equation with variable nonlinear coupling. We study its properties and present arguments regarding its nature and interpretation, including the connection to Landauer’s principle. We also demonstrate that our model is able to describe linear quantum-mechanical systems with shape-changing external potentials.

Coelho, DB, Pimenta, EM, Rosse, IC, Veneroso, C, Pussieldi, GDA, Becker, LK, De Oliveira, EC, Carvalho, MRS, and Silami-Garcia, E. Alpha-actinin-3 R577X polymorphism influences muscle damage and hormonal responses after a soccer game. J Strength Cond Res 33(10): 2655–2664, 2019—The purpose of this study was to evaluate indicators of muscle damage and hormonal responses after soccer matches and its relation to alpha-actinin-3 (ACTN3) gene expression (XX vs. RR/RX), considering that the R allele produces alpha-actinin-3 and provides greater muscle strength and power. Thirty players (10 XX and 20 RR/RX) younger than 16 years were evaluated in this study. Blood samples were collected immediately before, after, 2, and 4 hours after the games to assess muscle damage (creatine kinase [CK] and alpha-actin) and hormonal responses (interleukin-6 [IL-6], cortisol, and testosterone). Postgame CK was higher as compared to the pregame values in both groups and it was also higher in the RR/RX (p < 0.05) than in the XX. The concentrations of alpha-actin and IL-6 were similar for both groups and did not change over time. Testosterone was increased after the game only in the RR/RX group (p < 0.05). Cortisol concentrations in group RR/RX were higher immediately after the game than before the game, and 2 and 4 hours after the game the concentration decreased (p < 0.05). The RR and RX individuals presented higher markers of muscle microtrauma and hormonal stress, probably because they performed more speed and power actions during the game, which is a self-regulated activity. From the different responses presented by RR/RX and XX genotypes, we conclude that the genotypic profile should be taken into account when planning training workloads and recovery of athletes.

Abstract
Chan, M, MacInnis, MJ, Koch, S, MacLeod, KE, Lohse, KR, Gallo, ME, Sheel, AW, and Koehle, MS. Cardiopulmonary demand of 16-kg kettlebell snatches in simulated Girevoy Sport. J Strength Cond Res 34(6): 1625–1633, 2020—Kettlebell lifting has become popular both as a strength and conditioning training tool and as a sport in and of itself: Girevoy Sport (GS). Although several kettlebell multimovement protocols have been analyzed, little research has attempted to quantify the aerobic stimulus of the individual events in GS, which could better inform kettlebell-related exercise prescription. The purpose of this study was to quantify the cardiopulmonary demand, assessed primarily by oxygen consumption (V̇o
2) and heart rate (HR), of continuous high-intensity kettlebell snatches—under conditions relevant to GS—and to compare this demand with a more traditional graded rowing ergometer maximal exercise test. Ten male participants (age = 28.4 ± 4.6 years, height = 185 ± 7 cm, body mass = 95.1 ± 14.9 kg) completed (a) a graded-exercise test on a rowing ergometer to determine maximal oxygen consumption (V̇o
2max) and maximal heart rate (HRmax) and (b) a graded-exercise test consisting of continuous 16-kg kettlebell snatches to determine peak oxygen consumption (V̇o
2peak) and peak heart rate (HRpeak) during a simulated GS snatch event. Subjects achieved a V̇o
2max of 45.7 ± 6.7 ml·kg−1·min−1 and HRmax of 177 ± 8.3 b·min–1 on the rowing ergometer. The kettlebell snatch test produced a V̇o
2peak of 37.6 ± 4.4 ml·kg−1·min−1 (82.7 ± 6.5% V̇o
2max) and a HRpeak of 174 ± 10 b·min–1 (98.0 ± 3.4% HRmax). These findings suggest that GS kettlebell snatches with 16-kg can provide an adequate aerobic stimulus to improve cardiorespiratory fitness in those with a V̇o
2max of ≤51 ml·kg−1·min−1, according to aerobic training recommendations from the American College of Sports Medicine.

García-Pinillos, F, Roche-Seruendo, LE, Marcen-Cinca, N, Marco-Contreras, LA, and Latorre-Román, PA. Absolute reliability and concurrent validity of the Stryd system for the assessment of running stride kinematics at different velocities. J Strength Cond Res 35(1): 78–84, 2021—This study aimed to determine the absolute reliability and to evaluate the concurrent validity of the Stryd system for measuring spatiotemporal variables during running at different velocities (8–20 km·h−1) by comparing data with another widely used device (the OptoGait system). Eighteen trained male endurance runners performed an incremental running test (8–20 km·h−1 with 3-minute stages) on a treadmill. Spatiotemporal parameters (contact time [CT], flight time [FT], step length [SL], and step frequency [SF]) were measured using 2 different devices (Stryd and OptoGait systems). The Stryd system showed a coefficient of variation (CV) <3%, except for FT (3.7–11.6%). The OptoGait achieved CV <4%, except for FT (6.0–30.6%). Pearson correlation analysis showed large correlations for CT and FT, and almost perfect for SL and SF over the entire protocol. The intraclass correlation coefficients partially support those results. Paired t-tests showed that CT was underestimated (p < 0.05, effect size [ES] > 0.7; ∼4–8%), FT overestimated (p < 0.05, ES > 0.7; ∼7–65%), whereas SL and SF were very similar between systems (ES < 0.1, with differences <1%). The Stryd is a practical portable device that is reliable for measuring CT, FT, SL, and SF during running. It provides accurate SL and SF measures but underestimates CT (0.5–8%) and overestimates FT (3–67%) compared with a photocell-based system.

da Silva Araujo, G, Behm, DG, Monteiro, ER, de Melo Fiuza, AGF, Gomes, TM, Vianna, JM, Reis, MS, and da Silva Novaes, J. Order effects of resistance and stretching exercises on heart rate variability and blood pressure in healthy adults. J Strength Cond Res 33(10): 2684–2693, 2019—The purpose of this study was to compare the acute effect of different combinations and order of resistance exercise (RE) and stretching exercise (SE) on heart rate variability, systolic blood pressure (SBP), and diastolic blood pressure (DBP). Twenty subjects, recreationally trained, performed 5 sessions in a random order: (a) SE followed by RE no rest (SE + RE), (b) RE followed by SE no rest (RE + SE), (c) SE between RE sets (SBE), (d) SE isolated, and (e) RE isolated. Heart rate variability, SBP, and DBP were collected for 15 minutes before (baseline) and 60 minutes after each experimental session. A significant decrease was found for standardized deviation of differences between adjacent normal r-r intervals (RMSSDms) SE + RE (−50.79%), SE (+9.2%), SBE (−42.8%), and RE (−46.3%). Similarly, a significant increase was found for LFnu in SE + RE (+12.8%) and SBE (+16.6%). In addition, a significant decrease was found for HFnu in SE + RE (−34.8%) and SBE (−39.7%). Finally, a significant decrease was found for SBP in SE (−6.1%). In conclusion, this study indicated that SE followed by RE promotes a reduction in LFnu and RMSSDnu, with trivial to small magnitude decreases in SBP. Therefore, performing SE either before or between RE would be an important exercise prescription recommendation to lower cardiac load and consequently greater safety.

ABSTRACT
THE STRENGTH AND CONDITIONING (S&C) COACH'S ROLE COULD BE DESCRIBED AS BEING SIMILAR TO OTHER ALLIED HEALTH PROFESSIONALS (E.G., PHYSICAL THERAPISTS, PHYSIO-THERAPISTS, AND SPORTS PHYSICIANS) WHO PROVIDE A SERVICE TO A CLIENT—EITHER INDIVIDUAL ATHLETE OR TEAM. SUCH A RELATIONSHIP SHOULD BE BASED ON RESPECT, MUTUAL RESPONSIBILITY, AND ETHICAL EQUALITY. TO THIS END, THERE SHOULD BE AN EXPECTATION, FROM THE ATHLETE, THAT THE S&C COACH WILL BE DEVELOPING TRAINING PROGRAMS THAT CONFORM TO SOME MODEL OF GOOD ETHICAL PRACTICE. THIS ARTICLE PRESENTS A MODEL THAT CAN BE USED BY THE S&C PROFESSIONAL TO GUIDE THEIR ETHICAL PRACTICE.
