Tethered force at lower limbs and swimming during a 30 s exercise bout and its association with 50 m front crawl performance

BACKGROUND: The capacity to produce force should be promoted especially for the fastest swimming events. AIM: This study aimed to analyze the effects of different test periods in mean, maximal and coefficient of force variation and to correlate the coefficient of force variation and 50m front crawl time. METHOD: Twelve well trained swimmers (age: 22.33±8.08 years, 1.69±0.48 m height, body mass 56.08±7.86 kg) randomly performed three maximal 30s repetitions of full swimming and lower limbs actions in front crawl swimming technique with ~15min resting period. A load cell system permitted the continuous measurement of exerted tethered forces, and 50m time was registered as the best time obtained at 12 months before the test. RESULTS: Mean swimming force was greater at 10s compared to 20 and 30s period (26.40 [20.66-54.20], 25.33 [21.70-52.35] and 21.39 [17.91-43.98] respectively, p<0.05). Mean, maximal and force coefficient variation at tethered test with full swimming were higher than lower limbs (24.37 vs. 12.71, 77.97 vs. 39.78, 0.77 vs. 0.49 respectively, p<0.05). Strong and inverse correlations were noticed between coefficient of force variation at 10 s during full swimming, at 20s during kicking and performance (28.75s [26.20-30.68s];r=-0.75;p<0.01). Very strong correlation was noticed between coefficient of force variation during swimming at 20s, 30s and performance (r=-0.91 and -0.92;p<0.0001). CONCLUSION: Mean swimming force at full swim and lower limbs is affected by the period of the 30s maximal tethered swimming test and is associated with performance.Data reported may be used as reference for setting training strategies at short distance events.
Boundaries for polydisc algebras in infinite dimensions

Abstract Let AB be the algebra of all bounded continuous functions on the closed unit ball B of c0, analytic on the open unit ball, with sup norm, and let AU be the sub-algebra of AB of those functions which are uniformly continuous on B. Call a set S ⊂ B a boundary of AB (AU) if for every f ∈ AB (f ∈AU, respectively). In the paper we study the boundaries of AB and AU. We give a complete description of the boundaries of AU and present some necessary and some sufficient conditions for a set to be a boundary of AB. We also give some examples of boundaries.
Analysis of an Association between Preterm Birth and Parental Educational Level in Japan Using National Data

Preterm birth rate depending on parental educational level in recent years has not been surveyed in Japan. In this study, we showed the trend in preterm birth rate depending on parental educational level from 2000 to 2020 by linking data from the Census regarding individuals’ educational level and parents in birth data of the vital statistics. Four types of parental educational level, namely junior high school, high school, technical school or junior college, and university or graduate school, were compared. Slope and relative indexes of inequality for preterm birth by educational level were computed by binomial models. Data on 3,148,711 births and 381,129,294 people were used in the analysis, and data on 777,086 singleton births were used after data linkage. The preterm birth rate (%) for junior high school graduate mothers and fathers was 5.07 and 5.21 in 2020, respectively. Contrarily, the preterm birth rate (%) for parents who graduated from a university or graduate school was 4.24 for mothers and 4.39 for fathers, and the rate tended to increase as educational level decreased, irrespective of parental gender. Results of inequality indexes showed that a statistically significant inequality by parental educational level persisted from 2000 to 2020.
Cochrane in CORR®: Preventing Occupational Stress in Healthcare Workers.

Wellness and burnout among healthcare workers, including physicians, has been prominently featured recently within the medical community and media, including in the pages of Clinical Orthopaedics and Related Research [9, 19]. The term “burnout” was first coined by American psychologist Herbert Freudenberger, who described burnout as “the consequences of prolonged stress and anxiety experienced by people working in the healing professions” [7, 12]. A survey of 6880 physicians among all fields in 2011 found that 45.5% reported symptoms of burnout [16]. The 2014 update of a survey of 3310 physicians showed a rise to 54.4% [14]. Most recently in 2018, a survey of 1643 Chinese arthroplasty surgeons with 202 responses reported burnout in 85.1% of respondents [20]. Burnout is often accompanied and complicated by feelings of depression, substance abuse, interpersonal conflicts, and suicidal ideation [12]. As of 2015, approximately 300 to 400 physicians commit suicide each year in the United States [8]. This is approximately one physician per day, or three to four averaged sized American medical school classes per year, committing suicide [3]. Burnout is on the rise among physicians, and orthopaedic surgeons are no exception. The American Orthopaedic Association (AOA) performed a survey of 195 orthopaedic chairs and program directors to assess the severity of burnout and career dissatisfaction [1, 14]. In 2002, 10% reported being dissatisfied; by 2007, this had already increased to 26% [14], which attracted the attention of AOA and led them to encourage the integration of strategies to identify at risk physicians in a nonpunitive manner with treatment and education programs [1, 14]. Quite apart from its effect on physician satisfaction, burnout places patients at risk, as it is associated with
Order dispatch optimization with considering flexible one-to-three matching strategy under hybrid ride-hailing service modes

ABSTRACT In practice, the ride-hailing platform generally provides two products: express services and ridesplitting services, and driver resources are usually shared across these two products on the supply side, i.e., hybrid ride-hailing mode. This study tackles the order dispatch problem with considering flexible one-to-three matching strategy under hybrid modes. In this problem, if a driver serves express requests, only one order can be matched with; if a driver serves ridesplitting requests, this driver can be matched with at most three orders simultaneously or sequentially. Considering one-to-three matching, en-route matching, and multiple passengers per order, this problem is formulated as a multi-objective integer programming, a hierarchical approach is adopted to address it. Using the ride-hailing trip data, we examine characteristics of this problem, such as the impact of service priority and the benefits of one-to-three matching. Finally, some beneficial management implications are proposed to improve the operation of the ride-hailing service.
Nexus of Training and Development, Organizational Learning Capability, and Organizational Performance in the Service Sector

This article investigates the expansion of organizational learning capabilities (OLC) and its growing utilization in the organization in order to identify whether OLC affects the relationship between training and development and organizational performance. This study further explores the correlation between organizational learning capabilities and organizational performance, offering insight into the different understandings of organizational triumph related to OLC. This research was conducted via survey method and data were collected from five service industries in Khyber Pakhtunkhwa (KP), Pakistan. A data sample of 300 employees was analyzed using quantitative approaches, such as descriptive statistics and partial least squares structural equation modeling (PLS-SEM). The results of the article addressed issues that are related to human capital regarding OLC, including training and development aspects which were not discussed by the literature in the past. The main findings of this paper are the formulation of an empirically and theoretically supported model related to the effect of OLC on the relationship between training and development and organizational performance. On the other hand, this study signifies that OLC is a better instrument for enhancing organizational performance, as well as in dealing with today’s indeterminate and continuously challenging economic atmosphere. This study is the first of its nature to shed light on training and development, organizational learning capabilities, and organizational performance in the service sector of KP, Pakistan.
The abundant elements in interstellar dust

We explore the incorporation of the cosmically abundant species O, C, N, Mg, Si, Fe, and S into interstellar dust. Column densities based on Goddard High Resolution Spectrograph 3.5 km/s resolution measurements from the literature for eight individual absorbing regions toward five lines of sight are used. Corrections are applied as needed in order to account for recent improvements in oscillator strengths. In order to acquire the most accurate column densities, and check on the accuracy of the oscillator strengths, we compare column densities based on the very strong Lorentzian damped lines of C II, O I, N I, and Mg II with results for the weak lines of these species, and confirm the previously determined f-values for O I lambda 1335, C II lambda 2325, and N I lambda lambda 1159, 1160. New empirical f-values of 1.25 x 10(exp -3) and 6.25 x 10(exp -4), respectively, are derived for the Mg II weak doublet at 1239 and 1240 A. Assuming a cosmic reference abundance based on solar and B star values, we derive depletions and dust-phase abundances which suggest that more than 70% of the available Mg and Fe is incorporated into dust-grain cores, whereas only 35% of the silicon is. This implies that oxides are important constituents of the grain core population. Mg and Fe atoms are mantled onto grain cores in a ratio of 1.8 to 1, whereas approximately 4.0 Si atoms are in the mantle per Fe atom. Since Si is not expected to accrete onto silicate or graphite grains, other grain cores, perhaps oxides and/or metallic Fe, may provide mantling sites for this species. The abundances of Fe and Mg in mantles would imply that graphite grains must have a substantial coating unless oxides provide significant mantling sites for these species. The abundance of O and N in the dust phase as implied by the solar reference abundance values are difficult to reconcile with the fact that these elements are not expected to participate in mantle formation, and the 3.1 micrometer H2O ice feature is not seen in absorption toward stars similar to those studied. The B star reference abundances for O and N, however, imply that no mantling of these species has occurred. The dust-phase abundance for C implied by solar reference abundances agrees with predictions for the number of graphite grains needed to produce the 2175 A bump. B star reference abundances, however, suggest that the abundance of C in the dust phase is not always sufficient to produce the bump.
Revisiting the Impact of Measurement Quality on Targeted Structural Model Fit Indexes in Structural Equation Modeling

Abstract This study examined the false positive rates and sensitivity of structural fit indexes to structural misspecification in SEM. The impact of sample size, model size, the magnitude of standardized factor loadings, and misspecified path effect on the fit indexes was also investigated. The structural fit indexes examined in this study included RMSEA-P, C9, C10 recommended by Lance et al., and C9S, C10S, RMSEAS, and CFIS proposed by McNeish and Hancock. The results in the present study showed that the false positive rates of C9S and C10S were high when the sample size was small or when factor loadings were low, although their sensitivity was negligibly impacted by the size of factor loadings. The higher sensitivity of RSMEA-P, C9, and C10 was observed in conditions with more observed items with higher factor loadings. Empirical implications for applied researchers were discussed.
Dielectric Material Technologies for 2-D Semiconductor Transistor Scaling

The 2-D semiconductors have been recognized as promising channel materials for the ultimately scaled transistor technologies beyond silicon. An essential technology enabler for 2-D semiconductor electronics is the development of dielectric materials interfaced with 2-D semiconductors. In this review article, we overview different types of dielectric materials that are suitable for different application scenarios, including high-<inline-formula> <tex-math notation="LaTeX">${k}$ </tex-math></inline-formula> gate dielectrics, low-<inline-formula> <tex-math notation="LaTeX">${k}$ </tex-math></inline-formula> spacers, and thermal management materials under the paradigm of 2-D semiconductor electronics. A material selection guideline for dielectric materials and the key process technology modules are discussed in detail. A special emphasis is made on how each of the dielectric technologies may enable the further scaling and practical applications of 2-D semiconductor transistors. The state-of-the-art device technologies are summarized, and the remaining challenges toward practical applications are discussed from the industrial perspective.
Azospirillum brasilense promotes increases in growth and nitrogen use efficiency of maize genotypes

The development of cultivars with an improved nitrogen use efficiency (NUE) together with the application of plant growth-promoting bacteria is considered one of the main strategies for reduction of fertilizers use. In this sense, this study: i) evaluated the effect of Azospirillum brasilense on the initial development of maize genotypes; ii) investigated the influence of A. brasilense inoculation on NUE under nitrogen deficit; and iii) sought for more NUE genotypes with higher responsiveness to A. brasilense inoculation. Twenty-seven maize genotypes were evaluated in three independent experiments. The first evaluated the initial development of maize genotypes with and without A. brasilense (strain Ab-V5) inoculation of seeds on germination paper in a growth chamber. The second and third experiments were carried out in a greenhouse using Leonard pots and pots with substrate, respectively, and the genotypes were evaluated at high nitrogen, low nitrogen and low nitrogen plus A. brasilense Ab-V5 inoculation. The inoculation of seeds with A. brasilense Ab-V5 intensified plant growth, improved biochemical traits and raised NUE under nitrogen deficit. The inoculation of seeds with A. brasilense can be considered an economically viable and environmentally sustainable strategy for maize cultivation.
The Local Structure of Random Processes

A tangent process of a random process X at a point z is defined to be the limit in distribution of some sequence of scaled enlargements of X about z. The main result of the paper is that a tangent process must be self‐similar with stationary increments, at almost all points z where the tangent process is essentially unique. The consequences for tangent processes of certain classes of process are examined, including stable processes and processes with independent increments where unique tangent processes are Lévy processes.
Resonant acceleration and heating of solar wind ions by dispersive ion cyclotron waves

We investigate the preferential acceleration and heating of solar wind alpha particles by the resonant cyclotron interaction with parallel-propagating left-hand-polarized ion cyclotron waves. The Alfven wave spectrum equation is generalized to multi-ion plasmas and a Kolmogorov type of cascade effect is introduced to transfer energy from the low-frequency Alfven waves to the high-frequency ion cyclotron waves, which are assumed to be entirely dissipated by the wave-particle interaction. In order to distribute the dissipated wave energy among the alphas and protons, the quasi-linear theory of the wave-particle interaction is used along with the cold plasma dispersion relation, and a power law spectrum of the ion cyclotron waves is assumed, with the spectral index as a free parameter of the model. The set of three-fluid solar wind equations and the Alfven wave spectrum equation are then solved in order to find fast solar wind solutions. It is found that the effect of the alpha particles on the dispersion relation, omitted in most previous wave-driven solar wind models, has a significant influence on the preferential acceleration and heating of the alphas, especially in the region close to the Sun. With this effect included, the alpha particles can be accelerated to a bulk flow speed faster than the protons by a few hundred kilometers per second and heated by the resonant cyclotron interaction to more than mass-proportional temperature values at several solar radii. However, this mechanism does not yield a differential speed of the order of an Alfven speed and a mass-proportional temperature for the alphas beyond 0.3 AU, as observed, which confirms the same conclusion reached previously by Isenberg and Hollweg [1983] for nondispersive ion cyclotron waves.
Rationalization of Islamic Legal Considerations in Marriage Dispensation: A Lesson from Katingan, Central Kalimantan

This paper finds the importance of paying attention to the psychological readiness of children as consideration in granting a marriage dispensation. Katingan Regency Local Regulation Number 9 of 2018 requires applicants for marital dispensation to check their psychological health. This study investigates how such requirements help judges formulate rational legal considerations in handling applications for a marriage dispensation. This study uses qualitative methods and analysis of the intertextuality of legal texts. Kasongan Religious Court Decision Number 39/Pdt.P/2022/PA.Ksn has taken advantage of the implementation of this provision. The judge rejected the application for a marriage dispensation because the results of the hospital's assessment showed that the prospective bride and groom were not psychologically prepared. This decision ruled out the reasons for the applicants on the pretext of only avoiding adultery. The legal considerations refer to the essential objective of Islamic law: the best benefit (maslahat) for children.
Propagation characteristics on line-of-sight over-sea paths in Japan

The results of line-of-sight over-sea propagation measurements over 37.2- and 35.5-km paths near Tokyo, Japan, are presented. Measurements of the fading (0.25, 3.99, 4.15, 6.72, and 18.0 GHz) of the cross polarization distortion (linear polarized wave at 4.15 GHz and circular polarized wave at 6.72 GHz) of the space diversity effect at 4.15 GHz, of the height-gain patterns at 6.72 GHz, and of the frequency-sweep patterns from 18 GHz to 22 GHz are included. The following statistical results are presented: the frequency, seasonal, and path dependence of fading; the effect of different fading occurrence mechanisms, such as K-type, duct-type, and distorted raindrops, for the cross polarization distortion; the diversity improvement factor; the effective reflection coefficient of sea surface; and the path-length difference between direct and sea reflected waves.
Controlling the Electrical and the Optical Properties of Amorphous IGZO Films Prepared by Using Pulsed Laser Deposition

and scanning electron microscopy data suggest that the a-IGZO starts to crystallize around 600 C. The electrical resistivity and the carrier density of the a-IGZO film showed large variations with changes in the substrate temperature or the oxygen pressure. The resistivity of the a-IGZO film was minimized at 200 C and 10 mTorr. The energy gap estimated from the optical transmittance showed an increasing tendency with increasing of substrate temperature up to 200 C or with increasing of oxygen pressure up to 100 mTorr, and it was about 3.0 eV at 200 C and 10 mTorr. Remarkably, the optical transmittance for the a-IGZO film showed a clear variation in the violet color region with changing of the substrate temperature and oxygen pressure. Our results suggest that both the substrate temperature and the oxygen pressure can be exploited as key parameters to control the electrical and the optical properties of a-IGZO films.
On an oscillatory point force in a rotating stratified fluid

The forced oscillations due to a point forcing effect in an infinite or contained, inviscid, incompressible, rotating, stratified fluid are investigated taking into account the density variation in the inertia terms in the linearized equations of motion. The solutions are obtained in closed form using generalized Fourier transforms. Solutions are presented for a medium bounded by a finite cylinder when the oscillatory forcing effect is acting at a point on the axis of the cylinder. In both the unbounded and bounded case, there exist characteristic cones emanating from the point of application of the force on which either the pressure or its derivatives are discontinuous. The perfect resonance existing at certain frequencies in an unbounded or bounded homogeneous fluid is avoided in the case of a confined stratified fluid.
Theory of J-characteristics for fractional factorial designs and projection justification of minimum G2-aberration

Deng & Tang (1999) introduced the generalised resolution and minimum G-aberration criteria for assessing nonregular fractional factorials. In Tang & Deng (1999), a relaxed variant of minimum G-aberration, called minimum G 2 -aberration, is proposed and studied. These criteria are defined using a set of J values, called J-characteristics. In this paper, we show that a factorial design is uniquely determined by its J-characteristics just as a regular factorial design is uniquely determined by its defining relation. The theorem is given through an explicit formula that relates the set of design points to that of J-characteristics. Through this formula, projection justification of minimum G 2 -aberration is established.
A NEW SCORPION OF THE GENUS Buthoscorpio WERNER, 1936 (SCORPIONES: BUTHIDAE) FROM KERALA, INDIA

A new scorpion species of the genus Buthoscorpio Werner, 1936 is described from Chinnar Wildlife Sanctuary, Idukki District, Kerala, India. The new species, Buthoscorpio chinnarensis can be distingued from the other congeners by having (1) carapace with scattered granulation on lateral portions; (2) median eyes situated anteriorly in the ratio 1:2; (3) prominent tubercles present at the basal portion of the pedipalp femur; (4) marginal lamellae of pectines composed of three pieces and middle lamellae comprises seven pieces of sclerites; (5) dorsal carinae present on metasomal segments III–V; (6) subaculear tubercle absent on telson; (7) Pectinal teeth count 14/16 (female paratypes with 17/17 and 16/17 respectively); (8) Metasomal segments I–IV wider than long, segment V longer than wide; (9) arrangement of lateral eyes. After the description of this new species, the total number of known species in the genus is raised to five; four in India and one in Sri Lanka.
Aerodynamic noise from a poroelastic edge with implications for the silent flight of owls

Abstract The interaction of a turbulent eddy with a semi-infinite poroelastic edge is examined with respect to the effects of both elasticity and porosity on the efficiency of aerodynamic noise generation. The scattering problem is solved using the Wiener–Hopf technique to identify the scaling dependence of the resulting aerodynamic noise on plate and flow properties, including the dependence on a characteristic flow velocity $U$ . Special attention is paid to the limiting cases of porous-rigid and impermeable–elastic plate conditions. Asymptotic analysis of these special cases reveals parametric limits where the far-field acoustic power scales like ${U}^{6} $ for a porous edge, and a new finite range of ${U}^{7} $ behaviour is found for an elastic edge, to be compared with the well-known ${U}^{5} $ dependence for a rigid impermeable edge. Further numerical results attempt to address how trailing-edge noise may be mitigated by porosity and flexibility and seek to deepen the understanding of how owls hunt in acoustic stealth.
