Maximal isokinetic peak torque and emg activity determined by shorter ranges of motion

Purpose. Isokinetic tests are often applied to assess muscular strength and EMG activity, however the specific ranges of motion used in testing (fully flexed or extended positions) might be constrictive and/or be painful for patients with injuries or undergoing rehabilitation. The aim of this study was to examine the effects of different ranges of motion (RoM) when determining maximal EMG during isokinetic knee flexion and extension with different types of contractions and velocities. Methods. Eighteen males had EMG activity recorded on the vastus lateralis, vastus medialis, semitendinosus and biceps femoris muscles during five maximal isokinetic concentric and eccentric contractions for the knee flexors and extensors at 60° · s –1 and 180° · s –1 . The root mean square of EMG was calculated at three different ranges of motion: (1) a full range of motion (90°–20° [0° = full knee extension]); (2) a range of motion of 20° (between 60°–80° and 40°–60° for knee extension and flexion, respectively) and (3) at a 10° interval around the angle where peak torque is produced. EMG measurements were statistically analyzed (ANOVA) to test for the range of motion, contraction velocity and contraction speed effects. Coefficients of variation and Pearson’s correlation coefficients were also calculated among the ranges of motion. Results. Predominantly similar (p > 0.05) and well-correlated EMG results (r > 0.7, p 0.001) were found among the ranges of motion. However, a lower coefficient of variation was found for the full range of motion, while the 10° interval around peak torque at 180° · s –1 had the highest coefficient, regardless of the type of contraction. Conclusions. Shorter ranges of motion at around the peak torque angle provides a reliable indicator when recording EMG activity during maximal isokinetic parameters. It may provide a safer alternative when testing patients with injuries or undergoing rehabilitation.
Likelihood Methods and Nonparametric Tests

Abstract Standard techniques of nonparametric statistics are related to likelihood procedures. In particular, rank tests and permutation tests in the regression problem are shown to be directly related to score function tests based on marginal and conditional likelihoods, respectively. The problem of estimating a population percentile is also examined from the viewpoint of marginal likelihood. These calculations tend to bring nonparametric procedures more closely in line with procedures adopted in parametric inference.
A Note on Br-infinity and KS-infinity formality

We extend M. Kontsevich's formality morphism to a homotopy braces morphism and to a G-infinity morphism. We show that this morphism is homotopic to D. Tamarkin's formality morphism, obtained using formality of the little disks operad, if in the latter construction one uses the Alekseev-Torossian associator. Similar statements can also be shown in the "chains" case (i.e., on Hochschild homology instead of cohomology). This settles two well known questions in deformation quantization and unifies the several known graphical constructions of formality morphisms and homotopies by Kontsevich, Shoikhet, Calaque, Rossi, Alm, Cattaneo, Felder and the author.
Minimizing emissions from grid-based hydrogen production in the United States

Low-carbon hydrogen could be an important component of a net-zero carbon economy, helping to mitigate emissions in a number of hard-to-abate sectors. The United States recently introduced an escalating production tax credit (PTC) to incentivize production of hydrogen meeting increasingly stringent embodied emissions thresholds. Hydrogen produced via electrolysis can qualify for the full subsidy under current federal accounting standards if the input electricity is generated by carbon-free resources, but may fail to do so if emitting resources are present in the generation mix. While use of behind-the-meter carbon-free electricity inputs can guarantee compliance with this standard, the PTC could also be structured to allow producers using grid-supplied electricity to qualify subject to certain clean energy procurement requirements. Herein we use electricity system capacity expansion modeling to quantitatively assess the impact of grid-connected electrolysis on the evolution of the power sector in the western United States through 2030 under multiple possible implementations of the clean hydrogen PTC. We find that subsidized grid-connected hydrogen production has the potential to induce additional emissions at effective rates worse than those of conventional, fossil-based hydrogen production pathways. Emissions can be minimized by requiring grid-based hydrogen producers to match 100% of their electricity consumption on an hourly basis with physically deliverable, ‘additional’ clean generation, which ensures effective emissions rates equivalent to electrolysis exclusively supplied by behind-the-meter carbon-free generation. While these requirements cannot eliminate indirect emissions caused by competition for limited clean resources, which we find to be a persistent result of large hydrogen production subsidies, they consistently outperform alternative approaches relying on relaxed time matching or marginal emissions accounting. Added hydrogen production costs from enforcing an hourly matching requirement rather than no requirements are less than $1 kg−1, and can be near zero if clean, firm electricity resources are available for procurement.

Observation of 4d ferromagnetism in free-standing Pd fine particles

We report on observation of 4d ferromagnetic ordering in pure Pd fine particles. Results of our dc magnetic measurements as a function of Pd particle size show that the magnetization increases rapidly with decreasing particle size; a sample with 59 A median radius at 1.8 K under 4 kOe shows a factor of nineteen larger magnetization than that of Pd bulk. We suggest that only the surface monolayers of Pd particles are magnetic. The ferromagnetic moment we deduced based on this assumption is 0.23 ± 0. 19μB per atom which is comparable to the value predicted by the ab initio calculation.
Stratigraphic evidence for culturally variable Indigenous fire regimes in ponderosa pine forests of the Mogollon Rim area, east-central Arizona

Abstract The impact of Indigenous populations on historical fire regimes has been controversial and beset by mismatches in the geographic scale of paleofire reconstructions and the scale of land-use behaviors. It is often assumed that anthropogenic burning is linearly related to population density and not different cultural practices. Here we take an off-site geoarchaeology strategy to reconstruct variability in historical fire regimes (<1000 years ago) at geographic scales that match the archaeological, ethnohistorical, and oral tradition evidence for variability in the intensity of Indigenous land use by two different cultural groups (Ancestral Pueblo and Western Apache). We use multiple, independent proxies from three localities in ponderosa pine (Pinus ponderosa) forests in east-Central Arizona to reconstruct fire regime variability during four phases of cultural use of different intensities. Elevated charcoal with domesticate pollen (Zea spp.) but otherwise unchanged forest pollen assemblages characterized intensive land use by Ancestral Pueblo people during an early phase, suggesting fire use to support agricultural activities. By contrast, a phase of intensive pre-reservation Western Apache land use corresponded to little change in charcoal, but had elevated ash-derived phosphorus and elevated grass and ruderal pollen suggestive of enhanced burning in fine fuels to promote economically important wild plants.
Performance predictions for micro-polarizer array imaging polarimeters

Imaging polarimetry is an emerging sensor technology that promises to improve the performance of sensor systems when used as an adjunct to conventional intensity-based imaging. Several prototype systems capable of being deployed from aircraft are under development. One system has successfully completed an airborne military utility assessment and is being transitioned to operational status. As this technology continues to gain interest, it will become necessary to both accurately predict the performance of proposed systems before they are fabricated as well as develop modeling and simulation tools that will allow their performance to be evaluated for various operational scenarios. In this paper we develop several performance prediction tools that can be used to address these needs; these models are based on the micro-polarizer array (MPA) implementation of imaging polarimeters as this architecture is at the forefront in the development of deployable systems. Focal plane array (FPA) well size, polarizer extinction ratio (ER), pixel crosstalk, and processing algorithms all play roles in the performance that can be attained by a proposed sensor. We discuss the polarimetric response of an MPA-based polarimetric detector and use this model to illustrate the effects of these parameters on the sensor's polarimetric performance, which we cast as noise equivalent degree of linear polarization (NeDoLP). Key conclusions from these analyses are that the detector well size sets the upper limit on performance and that pixel crosstalk will likely the biggest contributor to polarimetric loss in most systems.
Recent Updates on the Role of the MicroRNA-10 Family in Gynecological Malignancies

The ever-increasing morbidity associated with gynecological malignancies constantly endangers the physical and psychological health of women. Since a long time, there has been an urgent need for a deeper understanding of the tumorigenesis and the development of gynecological cancer to identify new molecular markers for early diagnosis and metastatic disease prognosis and for the development of therapeutic targets. MicroRNAs are crucial cellular regulators. The microRNA-10 (miR-10) family has been found to play an integral role in the evolution of numerous cancer types. A comprehensive understanding of current studies on miR-10 could provide better insights into future research and clinical applications in related fields. This article reviews the latest research on the role of the miR-10 family in gynecological malignancies and the relevant molecular mechanism, mainly focusing on endometrial, cervical, and ovarian cancers.
A model atmosphere investigation of the effects of irradiation on the secondary star in a dwarf nova

We compute some exploratory model atmospheres and synthetic spectra for red dwarfs which incorporate the phenomena of irradiation. These models are suitable for studies of the secondary stars of the shorter period dwarf novae. Our models show that the incident flux produces marked changes in the temperature stratification and emitted spectra of the irradiated star. We investigate the effects of angle of incidence and, in an approximate manner, those of horizontal energy transfer. The latter factor has a particularly strong effect on our results. Our results have important implications for the interpretation of radial-velocity curves of dwarf novae
New Insights into MdSPS4-Mediated Sucrose Accumulation under Different Nitrogen Levels Revealed by Physiological and Transcriptomic Analysis

Nitrogen nutrition participates in many physiological processes and understanding the physiological and molecular mechanisms of apple responses to nitrogen is very significant for improving apple quality. This study excavated crucial genes that regulates sugar metabolism in response to nitrogen in apples through physiology and transcriptome analysis, so as to lay a theoretical foundation for improving fruit quality. In this paper, the content of sugar and organic acid in apple fruit at different developmental periods under different nitrogen levels (0, 150, 300, and 600 kg·hm−2) were determined. Then, the transcriptomic analysis was performed in 120 days after bloom (DAB) and 150 DAB. The results showed that the fructose and glucose content were the highest at 120 DAB under 600 kg·hm−2 nitrogen level. Meanwhile, different nitrogen treatments decreased malate content in 30 and 60 DAB. RNA-seq analysis revealed a total of 4537 UniGenes were identified as differentially expressed genes (DEGs) under nitrogen treatments. Among these DEGs, 2362 (52.06%) were up-regulated and 2175 (47.94%) were down-regulated. The gene co-expression clusters revealed that most DEGs were significantly annotated in the photosynthesis, glycolysis/gluconeogenesis, pyruvate metabolism, carbon metabolism, carbon fixation in photosynthetic organisms and plant hormone signal transduction pathways. The key transcription factor genes (ERF, NAC, WRKY, and C2H2 genes) were differentially expressed in apple fruit. Sugar and acid metabolism-related genes (e.g., HXK1, SPS4, SS2, PPC16-2, and MDH2 genes) exhibited significantly up-regulated expression at 120 DAB, whereas they were down-regulated at 150 DAB. Furthermore, the MdSPS4 gene overexpression positively promoted sucrose accumulation in apple callus and fruit. In conclusion, the combinational analysis of transcriptome and the functional validation of the MdSPS4 gene provides new insights into apple responses to different nitrogen levels.
Growth Performance of Silkworms (Tubifex sp.) Cultivated Using a Dry Substrate

Silkworms are one type of live food that has begun to be intensified in their cultivation activities in Indonesia. This study aimed to determine the effect of feeding/dried substrate in different doses on the growth performance of silkworms. The second aim was to determine the appropriate dose of dry substrate for silkworm cultivation. The study used a completely randomized design (CRD) with 4 treatments of dry media at a dose of 114 g/m2 (D10), 228 g/m2 (D20), and 324 g/m2 (D30) dan without media as a control (D0). With 3 replications for each treatment. A silkworm starter was obtained from cultivation for 30 days. The research was conducted at Warung Benih Farm in Depok for 33 days. Data were analyzed using Analysis of Variance (ANOVA) and Duncan's further test with a confidence level of 0.05. The results showed that absolute weight growth, population growth, and the best productivity were obtained in the treatment of substrate addition with a dose of 324 g/m2 (D30) with an absolute biomass growth of 48.67 g, population growth of 59458 individuals, & the productivity of 0.556 g/m2 was/cycle. Most of the water quality observations are in the relatively optimal range.
ROUGH FUZZY SETS AND FUZZY ROUGH SETS

The notion of a rough set introduced by Pawlak has often been compared to that of a fuzzy set, sometimes with a view to prove that one is more general, or, more useful than the other. In this paper we argue that both notions aim to different purposes. Seen this way, it is more natural to try to combine the two models of uncertainty (vagueness and coarseness) rather than to have them compete on the same problems. First, one may think of deriving the upper and lower approximations of a fuzzy set, when a reference scale is coarsened by means of an equivalence relation. We then come close to Caianiello's C-calculus. Shafer's concept of coarsened belief functions also belongs to the same line of thought. Another idea is to turn the equivalence relation into a fuzzy similarity relation, for the modeling of coarseness, as already proposed by Farinas del Cerro and Prade. Instead of using a similarity relation, we can start with fuzzy granules which make a fuzzy partition of the reference scale. The main contribut.
Familles p-adiques de formes automorphes pour GLn

In this paper, we give definitions for p-adic automorphic forms on any twisted form of GLn/Q compact at infinity, and we construct the "eigenvariety" of finite slope eigenforms of wild level Γ0(p), at a split place p. Besides some generalisation of Coleman-Mazur theory, the main ingredients are the very existence of the "orthonormal" p-adic analytic family of principal series of Γ0(p) and its most basic properties. We give analogues of Coleman’s "small slope forms are classical" and of Wan’s bounds for explicit radii for the families. As an application, we can construct n-dimensional padic families of non ordinary, n-dimensional, refined Galois representations coming from Shimura varieties of some unitary groups.

The Coupled Manifold

Abstract A new method is presented to detect the portion of variability connected between two climatic fields. The method is a realization of the Procrustes problem, and it is a generalization of methods for analysis of variance such as the singular value decomposition (SVD) or canonical correlation analysis (CCA). The Procrustes formulation offers a general framework to link together variance analysis methods, and regression methods, including as special cases SVD and CCA. Using this approach two fields can be divided into a subspace where variations of one field are connected to variations of the other field, the coupled manifold, and a subspace where variations are independent, the free manifold. The unified approach can be applied to prescribed SST experiments, in which case it recovers consistent results with other methods designed to identify the forced portion of variance, but it can now be extended also to the coupled case or to observations. Some examples from prescribed SST simulation experiment.
Effect of Delayed Anterior Cruciate Ligament Reconstruction on Repair of Concomitant Medial Meniscus Tears in Young Athletes

Background: Delayed anterior cruciate ligament (ACL) reconstruction (ACLR) is associated with an increased risk of meniscal injury. Limited data are available regarding the relationship between surgical delay and meniscal repairability in the setting of ACLR in young patients. Purpose: To determine whether time from ACL injury to primary ACLR was associated with the incidence of medial and/or lateral meniscal repair in young athletes who underwent meniscal treatment at the time of ACLR. Study Design: Case-control study; Level of evidence, 3. Methods: Records were retrospectively reviewed for patients aged 13 to 25 years who underwent primary ACLR between January 2017 and June 2020 by surgeons from a single academic orthopaedic surgery department. Demographic data were collected, and operative reports were reviewed to document all concomitant pathologies and procedures. Univariable and multivariable logistic regression analyses were used to determine factors associated with meniscal repair, including time elapsed from ACL injury to surgery. Results: Concomitant meniscal tears were identified and treated in 243 of 427 patients; their mean age was 17.9 ± 3.3 years, and approximately half (47.7%) of patients were female. There were 144 (59.3%) medial tears treated and 164 (67.5%) lateral tears treated; 65 (26.7%) patients had both medial and lateral tears treated. Median time from ACL injury to ACLR was 2.4 months (interquartile range, 1.4-4.7 months). Adjusted univariate analysis showed a statistically significant correlation between medial meniscal repair and time to surgery, with a 7% decreased incidence of medial meniscal repair per month elapsed between injury and surgery (odds ratio, 0.93 per month; 95% CI, 0.89-0.98; P = .006). No similar relationship was found between lateral meniscal repair and time to surgery (odds ratio, 1.02; 95% CI, 0.99-1.06; P = .24). Conclusion: In the setting of concomitant ACL and meniscal injuries, surgical delay decreased the incidence of medial meniscal repair in young athletes by 7% per month from time of injury.
Electrically Loaded Yagi-Uda Antenna Optimizations Using Characteristic Modes And Differential Evolution

Abstract A novel procedure based on characteristic modes (CM) and differential evolution (DE) algorithm is proposed for electrically loaded Yagi-Uda antenna synthesis. In this method, optimal Yagi- Uda antenna designs are realized by electrically loading, other than by tuning the sensitive physical dimensions. The traditional fullwave analysis in objective function evaluations is replaced by a simple summation of the CM, thus the optimization efficiency is greatly improved up to 4 orders. Antenna performances are compared to published results to illustrate the effectiveness of the present method.
The Role of Teledermatology During the COVID-19 Pandemic: A Narrative Review

Abstract Teledermatology represented one of the most important and useful tools during the COVID-19 pandemic era. Indeed, due to the severe restriction, and to reduce the spread of the infection, different measures were applied among different countries and hospitals to ensure a continuity of care for patients. In this scenario, teledermatology played a central role, especially in the management of patients suffering from chronic inflammatory skin diseases. The aim of this narrative review is to describe the role of teledermatology during the COVID-19 pandemic to analyze main strengths and limitations of this tool, as well as to provide future perspectives in clinical applications.
Ferromagnetism in ion implanted amorphous and nanocrystalline MnxGe1-x

The structural, electronic, and magnetic properties of a ${\mathrm{Mn}}_{x}{\mathrm{Ge}}_{1\ensuremath{-}x}$ alloy prepared through room-temperature ion implantation ($100\phantom{\rule{0.3em}{0ex}}\mathrm{keV}$, $2\ifmmode\times\else\texttimes\fi{}{10}^{16}\phantom{\rule{0.3em}{0ex}}\text{ions}∕{\mathrm{cm}}^{2}$) and subsequent $400\phantom{\rule{0.2em}{0ex}}\ifmmode^\circ\else\textdegree\fi{}\mathrm{C}$ annealing have been investigated with several experimental techniques. The as-implanted sample shows a quasi-Gaussian Mn concentration depth profile with a projected range (peak Mn concentration $x\ensuremath{\simeq}12\phantom{\rule{0.3em}{0ex}}\mathrm{at.}∕%$) at $55\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$ and end of range at $140\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$. The structural investigation shows that the overall implanted Ge layer is amorphous. In particular, up to a depth of $60\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$, the implanted layer is also porous and oxidized, whereas the deepest implanted region $(60\char21{}140\phantom{\rule{0.3em}{0ex}}\mathrm{nm})$ is purely composed of amorphous Ge with Mn atoms diluted in it. This sample manifests magnetic hysteresis up to $20\phantom{\rule{0.3em}{0ex}}\mathrm{K}$ and a strong nonlinear S-shaped magnetic response up to $150\phantom{\rule{0.3em}{0ex}}\mathrm{K}$. Upon annealing at $400\phantom{\rule{0.2em}{0ex}}\ifmmode^\circ\else\textdegree\fi{}\mathrm{C}$, the top porous layer remains essentially amorphous, whereas partial reconstruction into Ge nanocrystals ($\ensuremath{\sim}10\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$ in diameter) occurs in the $60\char21{}140\text{\ensuremath{-}}\mathrm{nm}$-deep implanted region. Part of the Mn atoms, mainly belonging to the top porous layer, further diffuses toward the surface and forms chemical bonds with O contaminants, becoming magnetically inactive. The other Mn atoms, mainly in the region between 60 and $140\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$ from the surface, remain trapped in the residual amorphous matrix or in the Ge nanocrystals, whereas formation of Mn-Ge extrinsic phases (like ${\mathrm{Mn}}_{11}{\mathrm{Ge}}_{8}$ and ${\mathrm{Mn}}_{5}{\mathrm{Ge}}_{3}$) is excluded. The magnetic response of the annealed sample originates from the existence of a soft and a harder magnetic component, assigned to the dilution of Mn atoms in residual amorphous Ge and Ge nanocrystals, respectively. The hard component, attributable to a ${\mathrm{Mn}}_{x}{\mathrm{Ge}}_{1\ensuremath{-}x}$ diluted magnetic semiconductor in nanocrystalline form, manifests magnetic hysteresis up to above $250\phantom{\rule{0.3em}{0ex}}\mathrm{K}$.
