Rare plants of threatened habitats – the Croatian case of Corrigiola litoralis L. (Caryophyllaceae)
Authors: Vuković Nina , Šegota Vedran , Alegro Antun , Sedlar Zorana 
Published: September 2017

AbstractCorrigiola litoralisis the only member of the genus in the Croatian flora. Most available data are more than 50 years old, and include only four localities in Croatia, exclusively in the islands of the Mediterranean region. During a floristic survey of the island of Molat (Northern Dalmatia) we recorded a small population in Zapuntelsko polje, in a damp, shallow depression, seasonally occurring as a temporary pond. Comparison with the existing literature shows thatC. litoralisoften occurs in Mediterranean temporary ponds and similar globally important and threatened habitats. We strongly believe that careful studies of populations ofC. litoralisand other species with similar ecologies are necessary in order to preserve these habitats and therefore propose actions to achieve this goal.

AbstractPolyamine oxidases (PAOs) are known to be involved in either the terminal catabolism or the back conversion of polyamines, which affect a range of physiological processes, including growth, development, and stress responses. In this study, based on genome-wide analysis, we identified five putative PAO genes (LuPAO1toLuPAO5) in flax (Linum usitatissimumL.) that contain the amino-oxidase domain and FAD-binding-domain. The expression analysis using quantitative real-time PCR revealed spatial variations in the expression ofLuPAOsin different organs. In addition, the expression level ofLuPAOsin the flax cell suspension culture was increased by treatment with methyl-jasmonate (MeJA) or pectin, but not with salicylic acid or chitosan. This indicates that LuPAOs might be involved in the MeJA-mediated biological activities. Taken together, our genome-wide analysis of PAO genes and expression profiling of these genes provide the first step toward the functional dissection of LuPAOs.
Higher weight on GL(3). I: The Eisenstein series
Authors: Buttcane Jack 
Published: September 2017

AbstractThe purpose of this paper is to collect and make explicit the results of Langlands [16], Bump [3], Miyazaki [18] and Manabe, Ishii and Oda [17] for theGL⁢(3){\mathrm{GL}(3)}Eisenstein series and Whittaker functions which are non-trivial onSO⁢(3,ℝ){\mathrm{SO}(3,\mathbb{R})}. The final goal for the series of papers is a complete and completely explicit spectral expansion forL2⁢(SL⁢(3,ℤ)∖SL⁢(3,ℝ)){L^{2}(\mathrm{SL}(3,\mathbb{Z})\setminus\mathrm{SL}(3,\mathbb{R}))}in the style of Duke, Friedlander and Iwaniec’s paper [8]. We derive a number of new results on the Whittaker functions and Eisenstein series, and give new, concrete proofs of the functional equations and spectral expansion in place of the general constructions of Langlands.
Frechet differentiability in Besov spaces in the optimal control of parabolic free boundary problems
Authors: Abdulla Ugur G. , Goldfarb Jonathan M. 
Published: September 2017

Abstract
We consider the inverse Stefan type free boundary problem, where information on the boundary heat flux and the density of the sources are missing and must be found along with the temperature and the free boundary.
We pursue the optimal control framework analyzed in [1, 2], where the boundary heat flux, the density of the sources, and the free boundary are components of the control vector.
We prove the Frechet differentiability in Besov spaces, and derive the formula for the Frechet differential under minimal regularity assumptions on the data.
The result implies a necessary condition for optimal control and opens the way
to the application of projective gradient methods in Besov spaces for the
numerical solution of the inverse Stefan problem.

Abstract
In this paper, we examine the hybrid optical fiber (OF)/free-space optics (FSO) architecture for a backhaul downlink over a wavelength-division multiplexing passive optical network (WDM-PON). The hybrid backhaul architecture is able to provide not only high-data-rate but also flexibility and quick deployment. The performance analysis is carried out for the hybrid OF/FSO backhaul downlink over a four-wavelength WDM-PON under the effect of four-wave mixing (FWM). The impact of atmospheric turbulence-induced fading and major noise components, including amplifier’s noise, shot noise, beat noise, background noise, and thermal noise, is also taken into account. The numerical results show that, although high transmitted power and amplifier’s gain at the transmitter side help to mitigate the impact of noise and fading, they should be limited to a specific value to avoid the influence of FWM. Therefore, the use of amplifier or avalanche photodiode at the receiver side would be a better solution to keep the bit-error rate (BER) at the low levels.
Urban Protests, Coups d’état and Post-Coup Regime Change
Authors: Gerling Lena 
Published: September 2017

AbstractThis study investigates the impact of urban protests on coup attempts and subsequent regime change in a sample of 39 Sub-Saharan African countries for the period from 1990 to 2007. Widespread public discontent, especially when occurring in urban centers, can act as a trigger of coups d’état in autocratic regimes. Yet, it is less clear how elites respond to protests in terms of post-coup institutional change and democratization. To account for potential endogeneity of protests and coups, variation in rainfall is used as an instrument for urban protests. The results show that rainfall-related urban protests raise the likelihood that a coup is staged, but have no effect on subsequent democratization.

AbstractIschemic heart disease and cerebral ischemia represent the leading causes of mortality worldwide. Both entities share risk factors, pathophisiology and etiologic aspects by means of a main common mechanism, atherosclerosis. The autors aimed to investigate differences and similarities in epidemiology and risk factors that could be found between both entities. In a retrospective sudy 403 patients were included and divided into two groups: group of 289 patients with history of myocardial infarction (AMI), and group of 114 patients with history of ischemic stroke (IS). All patients were evaluated for nonmodifiable risk faktors, which included age and sex, and modifiable, such as hypertension, dyslipidemia, diabetes, obesity, physical activity and smoking. Diff erences in some epidemiological aspects were also considered: occupation, marital status, alcohol consumption, exposure to stress. Patients with history of IS were significantly older then AMI patients (64.0 ± 9.9 vs 64.0 ± 9.9, p=0,028), with higher diastolic blood pressure (87,1 ± 10,2 vs 83,6 ± 10,4, p=0,003) and higher Sokolow-Lyon index in ECG, an also index of left ventricular hypertrophy (19,2 ± 9,1 vs 14,7 ± 6,5). Th ere were no significant differences between groups in the estimated body mass index and waist circumference. Differences between groups in stress exposure, occupation, alcohol consumption or physical activity were no significant. Patients in AMI group were more frequently male (199 (69%) vs 59 (52%), p=0,001), married (252 (87%) vs 88 (77%), p=0,037), smokers (162 (56%) vs 50 (44%), p=0,018) and with higher incidence od dyslipidemia (217 (75%) vs 73 (64%), p=0,019) compared with IS group. Incidence of arterial hypertension and diabetes was similar in both groups. Both entities share similar pathophysiological mechanisms and, consequently, main traditional risk factors. However, incidence of myocardial infarction increases with male sex, dyslipidemia, smoking and marital status, while incidense of ischemic stroke increases with age, higher diastolic blood pressure and also with ECG signs of left ventricular hypertrophy.

Hinchas e identidad. Alcances y limitaciones de la ética del aguante / Fans and identity. Scope and limitations of the ethics of endurance
Authors: Hasicic Germán 
Published: September 2017

A partir de un conjunto de entrevistas, diálogos, conversaciones y charlas informales se transformaron en los protagonistas de una investigación que aborda, entre otros ejes, las subjetividades desde una perspectiva socio-cultural y no meramente discursiva. Es decir, el análisis de las prácticas discursivas forma parte de un entramado analítico más amplio y complejo, articulándose a las preguntas por la violencia y la discriminación subyacentes. Para adentrarnos aún con mayor profundidad en la construcción identitaria de los hinchas de River, es preciso realizar una revisión de las discusiones y avances más significativos en torno a los estudios vinculados a la construcción de identidades futboleras: cómo se constituyen, perciben y autoperciben las identidades de estos sujetos, reparando en el comportamiento social permitido y atendiendo al uso de la violencia como práctica legítima/ilegítima, desarrollada en el capítulo anterior. Al hacerlo, hemos puesto en tensión una categoría moral: la ética del aguante.

Abstract
Weaving, D, Jones, B, Till, K, Marshall, P, Earle, K, and Abt, G. Quantifying the external and internal loads of professional rugby league training modes: consideration for concurrent field-based training prescription. J Strength Cond Res 34(12): 3514–3522, 2020—Practitioners prescribe numerous training modes to develop the varied physical qualities that professional rugby league players must express during competition. The aim of this study was to determine how the magnitude of external and internal training load per minute of time differs between modes in professional rugby league players. These data were collected from 17 players across 716 individual sessions (mean [SD] sessions: 42 [13] per player) which were categorized by mode (conditioning [CON], small-sided games, skills, and sprint training). Derived from global positioning systems (5 Hz with 15 Hz interpolation), the distances covered within arbitrary speed and metabolic power thresholds were determined to represent the external load. Session rating of perceived exertion and individualized training impulse represented the internal load. All data were made relative to the session duration. The differences in time-relative load methods between each mode were assessed using magnitude-based inferences. Small-sided games and CON very likely to almost certainly produced the greatest relative internal and external loads. Sprint training provided players with the greatest sprinting and maximal-power distances without a concomitant increase in the internal load. The metabolic power method complements speed-based quantification of the external load, particularly during small-sided games and skills training. In practice, establishing normative loads per minute of time for each mode can be useful to plan future training by multiplying this value by the planned session duration.

Abstract
Brumitt, J, Heiderscheit, B, Manske, R, Niemuth, PE, Mattocks, A, and Rauh, MJ. Preseason functional test scores are associated with future sports injury in female collegiate athletes. J Strength Cond Res 32(6): 1692–1701, 2018—Recent prospective cohort studies have reported preseason functional performance test (FPT) measures and associations with future risk of injury; however, the findings associated with these studies have been equivocal. The purpose of this study was to determine the ability of a battery of FPTs as a preseason screening tool to identify female Division III (D III) collegiate athletes who may be at risk for a noncontact time-loss injury to the lower quadrant (LQ = low back and lower extremities). One hundred six female D III athletes were recruited for this study. Athletes performed 3 FPTs: standing long jump (SLJ), single-leg hop (SLH) for distance, and the lower extremity functional test (LEFT). Time-loss sport-related injuries were tracked during the season. Thirty-two (24 initial and 8 subsequent) time-loss LQ injuries were sustained during the study. Ten of the 24 initial injuries occurred at the thigh and knee. At-risk athletes with suboptimal FPT measures (SLJ ≤79% ht; (B) SLH ≤64% ht; LEFT ≥118 seconds) had significantly greater rates of initial (7.2 per 1,000 athletic exposures [AEs]) and total (7.6 per 1,000 AEs) time-loss thigh or knee injuries than the referent group (0.9 per 1,000 AEs; 1.0 per 1,000 AEs, respectively). At-risk athletes were 9 times more likely to experience a thigh or knee injury (odds ratio [OR] = 9.7, confidence interval [CI]: 2.3–39.9; p = 0.002) than athletes in the referent group. At-risk athletes with a history of LQ sports injury and lower off-season training habits had an 18-fold increased risk of a time-loss thigh or knee injury during the season (adjusted OR = 18.7, CI: 3.0–118.1; p = 0.002). This battery of FPTs appears useful as a tool for identifying female D III athletes at risk of an LQ injury, especially to the thigh or knee region.

Abstract
Douglas, J, Pearson, S, Ross, A, and McGuigan, M. Kinetic determinants of reactive strength in highly trained sprint athletes. J Strength Cond Res 32(6): 1562–1570, 2018—The purpose of this study was to determine the braking and propulsive phase kinetic variables underpinning reactive strength in highly trained sprint athletes in comparison with a nonsprint–trained control group. Twelve highly trained sprint athletes and 12 nonsprint–trained participants performed drop jumps (DJs) from 0.25, 0.50, and 0.75 m onto a force plate. One familiarization session was followed by an experimental testing session within the same week. Reactive strength index (RSI), contact time, flight time, and leg stiffness were determined. Kinetic variables including force, power, and impulse were assessed within the braking and propulsive phases. Sprint-trained athletes demonstrated higher RSI vs. nonsprint–trained participants across all drop heights {3.02 vs. 2.02; ES (±90% confidence limit [CL]): 3.11 ± 0.86}. This difference was primarily attained by briefer contact times (0.16 vs. 0.22 seconds; effect size [ES]: −1.49 ± 0.53) with smaller differences observed for flight time (0.50 vs. 0.46 seconds; ES: 0.53 ± 0.58). Leg stiffness, braking and propulsive phase force, and power were higher in sprint-trained athletes. Very large differences were observed in mean braking force (51 vs. 38 N·kg−1; ES: 2.57 ± 0.73) which was closely associated with contact time (r ±90% CL: −0.93 ± 0.05). Sprint-trained athletes exhibited superior reactive strength than nonsprint–trained participants. This was due to the ability to strike the ground with a stiffer leg spring, an enhanced expression of braking force, and possibly an increased utilization of elastic structures. The DJ kinetic analysis provides additional insight into the determinants of reactive strength which may inform subsequent testing and training.

Abstract
Martín-Rodríguez, S, Loturco, I, Hunter, AM, Rodríguez-Ruiz, D, and Munguia-Izquierdo, D. Reliability and measurement error of tensiomyography to assess mechanical muscle function: A systematic review. J Strength Cond Res 31(12): 3524–3536, 2017—Interest in studying mechanical skeletal muscle function through tensiomyography (TMG) has increased in recent years. This systematic review aimed to (a) report the reliability and measurement error of all TMG parameters (i.e., maximum radial displacement of the muscle belly [Dm], contraction time [Tc], delay time [Td], half-relaxation time [½ Tr], and sustained contraction time [Ts]) and (b) to provide critical reflection on how to perform accurate and appropriate measurements for informing clinicians, exercise professionals, and researchers. A comprehensive literature search was performed of the Pubmed, Scopus, Science Direct, and Cochrane databases up to July 2017. Eight studies were included in this systematic review. Meta-analysis could not be performed because of the low quality of the evidence of some studies evaluated. Overall, the review of the 9 studies involving 158 participants revealed high relative reliability (intraclass correlation coefficient [ICC]) for Dm (0.91–0.99); moderate-to-high ICC for Ts (0.80–0.96), Tc (0.70–0.98), and ½ Tr (0.77–0.93); and low-to-high ICC for Td (0.60–0.98), independently of the evaluated muscles. In addition, absolute reliability (coefficient of variation [CV]) was low for all TMG parameters except for ½ Tr (CV = >20%), whereas measurement error indexes were high for this parameter. In conclusion, this study indicates that 3 of the TMG parameters (Dm, Td, and Tc) are highly reliable, whereas ½ Tr demonstrate insufficient reliability, and thus should not be used in future studies.

Abstract
Del Monte, MJ, Opar, DA, Timmins, RG, Ross, JA, Keogh, JWL, and Lorenzen, C. Hamstring myoelectrical activity during three different kettlebell swing exercises. J Strength Cond Res 34(7): 1953–1958, 2020—Kettlebell exercises have become an increasingly popular form of resistance training and component of lower-body rehabilitative training programs, despite a lack of scientific literature illustrating internal mechanisms and effectiveness of these approaches. Participants (n = 14) performed 3 different styles of kettlebell swings (hip hinge, squat, and double knee extension) and were assessed for medial hamstrings (MHs) and biceps femoris (BF) myoelectrical activity through surface electromyography (sEMG). Bipolar pregelled Ag/AgCl sEMG electrodes (10 mm diameter, 20 mm interelectrode distance) were placed on the participant's dominant limb after correct skin preparation. There was a main effect for swing type (p = 0.004), where the hip hinge swing elicited a greater overall MH and BF sEMG in comparison with the squat swing (mean difference = 3.92; 95% confidence interval [CI] = 1.53–6.32; p = 0.002) and the double knee extension swing (mean difference = 5.32; 95% CI = 0.80–9.83; p = 0.020). Across all swing types, normalized percentage of MH sEMG was significantly higher compared with the BF (mean difference = 9.93; 95% CI = 1.67–18.19; p = 0.022). The hip hinge kettlebell swing produced the greatest amount of hamstring sEMG for the 3 styles of kettlebell swings assessed. These findings have implications for the application of kettlebell swing exercises in strength and conditioning, injury prevention, and rehabilitation programs.
A Review of Physio-Biochemical Properties of Natural Fibers and Their Application in Soil Reinforcement

Published: September 2017

Abstract
The use of natural materials in place of synthetic materials has been the focus of research in sustainable geotechnics. In this context, use of natural plants/weeds as randomly distributed fiber-reinforced soil (RDFS) is extensively researched as a possible soil-improvement technique. The behavior of soil–natural fiber composite is dependent on the biochemical, physical, and mechanical properties of natural fibers. These natural-fiber properties are inherently different from those of conventional synthetic fibers, in which mechanical properties essentially govern the soil-fiber composite behavior. Very few geotechnical applications using natural geo-reinforcement materials have taken into consideration the biochemical and physical properties of the fiber. Moreover, there is rarely any systematic assessment and compilation of the work encompassing the application of natural fibers in soil reinforcement. This review summarizes the use of natural fibers in soil reinforcement. The study explores the importance and impact of natural-fiber properties on the performance of natural fibers in subsoil conditions. The treatment methodologies used in natural fibers to increase their longevity and reinforcement capabilities are also discussed. Based on this review, some key research gaps and the future scope of research have been highlighted. The review strongly recommends potential natural flora as RDFS fibers from a sustainability perspective. The review brings out the importance of biochemical composition (cellulose, lignin, hemicellulose, etc.) on fiber performance in subsoil conditions and highlights the use of treatment methodologies for fibers.
