The effect of anterior cruciate ligament reconstruction and RAMP lesion repair on psychological status.

There are few studies examining anterior cruciate ligament reconstruction (ACLR) and RAMP lesion repair. However, no studies have investigated the level of functional performance and psychological state after ACLR and all-inside RAMP lesion repair. The aim of this study is to determine the effect of ACLR and RAMP lesion repair on psychological status. ACLR and meniscal RAMP lesion repair were hypothesized to be associated with better psychological outcomes. This is a cohort study. Patients who underwent ACLR with semitendinosus and gracilis autografts by a single surgeon were determined retrospectively. Fifteen patients who underwent ACLR and all-inside meniscus RAMP lesion repair (ACLR-RR) and 15 patients who underwent isolated ACLR were compared. Patients were evaluated by a physiotherapist at least 9months after surgery. The primary outcome measure was anterior cruciate ligament-return to sports after injury (ACL-RSI), and the psychological status of the patients was examined. Secondary outcomes were visual analog scale (VAS), Tegner activity score, Lysholm knee score, single hop tests, and limb symmetry index (LSI). While pain intensity at rest and during movement was evaluated with VAS, functional performance level was evaluated with the Tegner activity score, the Lysholm knee score, single hop tests, and limb symmetry index (LSI). A significant difference was found in the ACL-RSI values in the ACLR-RR group compared to the isolated ACLR group (p = 0.02). The results of the groups in VAS scores at rest and during movement, Tegner activity levels, and Lysholm knee scores, in the intact and operated leg single hop tests (single leg hop, cross hop, triple hop, and six-meter hop test), and the LSI values in the single leg hop tests showed no significant difference. This study revealed different psychological outcomes and similar functional levels for ACLR and all-insidemeniscus RAMP repair compared with isolated ACLR. It was observed that the psychological status of patients with RAMP lesions should also be evaluated.

Electron Emission Cross Section from Methane under 250 keV Proton Impact

We measure double differential cross sections (DDCS) of electrons emitted from CH4 molecules in collisions with 250 keV protons. The projectile ions are obtained from a 400 kV electron cyclotron resonance-based ion accelerator (ECRIA). We study the energy and angular distributions of the electron DDCS. The observed double and single differential and the total cross section are compared with the state-of-the-art continuum distorted wave eikonal initial state (CDW-EIS) model predictions. Two different approaches are used considering the different target descriptions: complete neglect of differential overlap (CNDO) and molecular orbital (MO) approximations. The MO model uses two different scaling parameters (d = 0.7 and 1.0). In the energy distribution of the DDCS, the carbon KLL Auger line is also observed at 240 eV. The single differential cross section (SDCS) and total cross section (TCS) are derived. Both the MO-based CDW-EIS models are in good agreement with the experimental results; however, the CNDO approach overestimates the data.

Research on Constructing of Cross-level Theory Between Individual Behavior Cognition and Social Influence

Social ecological and health behavior theories consider the interplay between individual behavior cognition, norms of reference, collectives, and institutions, and social environment in understanding people's behavior. The theoretical model established on this basis can be divided into individual behavior theory and population behavior theory. So far, the two have been used independently by academics to understand behavioral problems. Theoretically speaking, the combination of the two theories will increase the explanatory extent of the real world and be more effective to problem intervention than a single level theory. This study attempts to combine the two theoretical models to form a new comprehensive theory, cross-level theory between individual behavioral cognition and social influence perspectives, which aims to explain the combined effect of cognition and social influences on behavior. The theory is based on theory and literature, and has certain rationality basis for theory constructing. The results of empirical research show that the theoretical model constructed was accepted, and social influence and have significant effects on behavior in a single level analysis and cross level model. Cross-level theory between individual behavioral cognition and social influence breaks through people of long-term inherent practice on behavioral theory research, opening up new perspective for research and application in this field. The integration of theories offers the potential for improved understanding of behaviors and a promising direction for future research efforts.

Determination of ecological plasticity and stability for female components of maize hybrids

Topicality. In Ukraine, a sharp manifestation of unfavorable climate elements for growing hybrid maize seeds, brought to the fore the tolerance of the female components of hybrids to environmental factors limiting the formation of potential yield. Therefore, the study and evaluation of the ecological plasticity and stability of female components are an urgent issue of the modern seed production of maize hybrids. Purpose. To determine the requirements of the female components of maize hybrids to environmental conditions. Materials and Methods. During the research, 20 female components of maize hybrids bred by the SE Institute of Grain Crops of NAAS were used. The female components were single cross sterile hybrids. The methodology of S. A. Eberhart, V. A. Russell, edited by A. Zykin and others, was used. The methodology is based on the calculation of two parameters: the linear regression coefficient bi (ecological plasticity) and the dispersion σd² (ecological stability). Results. The grain yield of the female components was determined in five years of the research. The influence of environmental conditions on the yield of female components of maize hybrids was determined. The female components were distributed according to the requirements for growing conditions. Conclusions. The most valuable, highly intensive female components include sister hybrids Kros253C, Kros256C, Kros247C and Kros238C with high environmental plasticity and stability. To realize the potential yield, they need a high agricultural background under favorable weather conditions. Female components Kros364M and Kros368M with high regression coefficient and root mean square deviation are less valuable because their high plasticity is combined with low yield stability. It is desirable to grow these female components only on a high agricultural background under favorable climatic conditions to get the maximum yield. Hybrids Kros254M, Kros255M, Kros266S, Kros277M, Kros301M, etc., have low environmental plasticity and high yield stability. These hybrids will give maximum returns for minimum costs in extensive cultivation. Keywords: female component, yield, hybrid, adaptation, regression coefficient, root mean square deviation, stability, plasticity

Quality Assessment of UGC Videos Based on Decomposition and Recomposition

The prevalence of short-video applications imposes more requirements for video quality assessment (VQA). User-generated content (UGC) videos are captured under an unprofessional environment, thus suffering from various dynamic degradations, such as camera shaking. To cover the dynamic degradations, existing recurrent neural network-based UGC-VQA methods can only provide implicit modeling, which is unclear and difficult to analyze. In this work, we consider explicit motion representation for dynamic degradations, and propose a motion-enhanced UGC-VQA method based on decomposition and recomposition. In the decomposition stage, a dual-stream decomposition module is built, and VQA task is decomposed into single frame-based quality assessment problem and cross frames-based motion understanding. The dual streams are well grounded on the two-pathway visual system during perception, and require no extra UGC data due to knowledge transfer. Hierarchical features from shallow to deep layers are gathered to narrow the gaps from tasks and domains. In the recomposition stage, a progressively residual aggregation module is built to recompose features from the dual streams. Representations with different layers and pathways are interacted and aggregated in a progressive and residual manner, which keeps a good trade-off between representation deficiency and redundancy. Extensive experiments on UGC-VQA databases verify that our method achieves the state-of-the-art performance and keeps a good capability of generalization.

Single Cross Filtered Direct Carotid Artery Revascularisation with Selective Flow Reversal

Single Cross Filtered Direct Carotid Artery Revascularisation with Selective Flow Reversal

Osteohistology and palaeobiology of giraffids from the Mio-Pliocene Langebaanweg (South Africa).

The reconstruction of life history traits, such as growth rate, age at maturity and age at death can be estimated from the histological analysis of long bones. Here, we studied 20 long bones (metapodials, tibia and femora) of Sivatherium hendeyi and Giraffa cf. Giraffa jumae recovered from the Miocene-Pliocene locality of Langebaanweg on the West Coast of South Africa. We analysed the long bone histology and growth marks of juvenile and adult specimens of these taxa. Our results show that bone tissue types and vascular canal orientation varies during ontogeny, as well as between the different skeletal elements, and also across single cross sections of bones. Majority of our specimens appear to be still growing, with only an adult metacarpal of S. hendeyi being skeletally mature as indicated by the presence of an outer circumferential layer. We propose that the growth marks preserved in the cortices of the bones studied are most likely related to multiple catastrophic events as opposed to being annual/seasonal.

Measurement of the ν_{e}-Nucleus Charged-Current Double-Differential Cross Section at ⟨E_{ν}⟩=2.4 GeV Using NOvA.

The inclusive electron neutrino charged-current cross section is measured in the NOvA near detector using 8.02×10^{20} protons-on-target in the NuMI beam. The sample of GeV electron neutrino interactions is the largest analyzed to date and is limited by ≃17% systematic rather than the ≃7.4% statistical uncertainties. The double-differential cross section in final-state electron energy and angle is presented for the first time, together with the single-differential dependence on Q^{2} (squared four-momentum transfer) and energy, in the range 1 GeV≤E_{ν}<6 GeV. Detailed comparisons are made to the predictions of the GENIE, GiBUU, NEUT, and NuWro neutrino event generators. The data do not strongly favor a model over the others consistently across all three cross sections measured, though some models have especially good or poor agreement in the single differential cross section vs Q^{2}.

A novel boundary tracing method without enrichment for modeling cracks and their propagation

A novel direct numerical modeling method for preexisting cracks and their propagation is developed based on the integral-generalized finite difference (IGFD) method which has an excellent performance in accuracy, flexibility, and convenience in dealing with boundary conditions. “Direct modeling” means discontinuities and their propagation are directly treated as boundaries of subdomains. The standard IGFD method for continuity problems is adopted in regions far from discontinuities, while modifications are required around the discontinuities. Some special treatments such as paired nodes and birth–death algorithms are employed to characterize the existing cracks and track the crack growth path. These techniques together constitute the extended IGFD (xIGFD) method realizing the application of IGFD method in discontinuity problems. Three specific technologies, xIGFD-A, xIGFD-B, and xIGFD-C are proposed to treat the growing nodes along the discontinuities. The xIGFD-A needs to number the newly generated nodes and add degrees of freedom for propagating cracks, which would change the dimensions of the global matrices, while the xIGFD-B and the xIGFD-C do not. The successful applications of this proposed xIGFD method as well as the comparisons with existing numerical methods in a series of examples involving quasi-static propagation of a single crack and cross cracks have fully proved its effectiveness and superiority. The proposed method neither needs enriched basis functions based on prior knowledge nor requires re-meshing operations, which shows the unity and conciseness of the discretization scheme for continuity and discontinuity problems. Therefore, it has application potential in more complex practical problems like hydraulic fracturing and fatigue cracks.

Characterization of unexpected blue-shifted single molecule fluorescence of JF646 and JF669 for SMLM.

JF-Halotag dyes have become increasingly popular for single-molecule localization microscopy (SMLM) because of their favorable photo-physics, ease of use, and compatibility with live-cell imaging. However under a variety of conditions, the excitation and emission wavelengths from individual emitters can deviate significantly from the commonly accepted characterization, leading to artifacts in two color SMLM data. Here I show results from multiple in vivo and in vitro experiments demonstrating 640nm mediated photo switching of JF669 from a conventional far-red signal to a 561nm excitable red single molecule signal. This result is exciting because it enables UV-free PALM experiments. UV radiation causes cell death, increases auto fluorescence, and induces cell stress, which may affect the behavior of labeled proteins or cellular processes of interest. Additionally, I present evidence of a subpopulation of JF646 molecules that can be excited by 561nm light, but emit red instead of far-red light. This unexpected fluorescence causes single molecule cross talk in the red channel, despite the commonly accepted characterization. This phenomenon is more apparent at low dye concentrations as well as high temperatures, suggesting that a self-interaction between JF646 molecules may bias the well characterized fluorescence, while in isolation JF646 may have significantly blue-shifted excitation and emission spectra. Together, these results show potentially useful photo-physical behavior of JF dyes, but also highlight the importance of careful controls when using synthetic dyes for single molecule localization microscopy.

SENSORY BRANDING IN GUJARAT- CONSUMER PERSPECTIVES POST COVID-19

Sensory branding is contemporary marketing that is connected with the senses with reference to brand. It is connected with customers on emotional and behavioral aspects. Many researchers have used sensory elements in their research such as vision, touch, sound, smell, and taste. (Lindstrom, 2005; Wansink, 2003). Considering strong research gap, current study investigates the consumer perception towards sensory branding. Current study has adopted single cross sectional research design based on primary research in Gujarat. Data analysis is done using SPSS. Study provides strong implications to marketers and society as a whole.

Forward inclusive jet productions in pA collisions

Motivated by recent experimental LHC measurements on the forward inclusive jet productions and based on our previous calculations on forward hadron productions, we calculate a single inclusive jet cross section in $pA$ collisions at forward rapidity within the color glass condensate framework up to the next-to-leading order. Moreover, with the application of a jet algorithm and proper subtraction of the rapidity and collinear divergences, we further demonstrate that the resulting next-to-leading-order hard coefficients are finite. In addition, in order to deal with the large logarithms that can potentially spoil the convergence of the perturbative expansion and improve the reliability of the numerical predictions, we introduce the collinear jet function and the threshold jet function and resum these large logarithms hidden in the hard coefficients.

Inbreeding and Genetic Erosion from a Finite Model of a Synthetic Formed with Single Crosses.

When a seed produced by a single-cross (SC) maize hybrid is sown, the resulting grain yield is usually lower than that of the hybrid due to the inbreeding generated. However, if a seed from a mixture of s hybrids were sown instead, the synthetic variety thus formed (SynSC) would have a lower inbreeding coefficient (FSynSC) and a higher grain yield. The grain yield s, the finite number of representatives of each parent SC (m) and the inbreeding coefficient of the parent lines of the SCs (F) are related to the FSynSC. In addition, randomness and the finite size of m can cause the loss of genes and genotypes and increase the FSynSC. The objectives of this study were to derive formulas for (1) expressing FSynSC in terms of m, F, and s, and (2) calculating the probability of the occurrence of gene and genotype loss. It was found that for the probability of no genotype being missing from the progeny representing a parent to be at least 0.95, it is necessary that m ≥ 15. It was also found that a sample size of 7 is sufficient for FSynSC to stabilize, more visibly as F is larger, and for the probability of the occurrence of erosion to be practically zero.

Genetic analyses of tropical maize lines under artificial infestation of fall armyworm and foliar diseases under optimum conditions.

Development and deployment of high-yielding maize varieties with native resistance to Fall armyworm (FAW), turcicum leaf blight (TLB), and gray leaf spot (GLS) infestation is critical for addressing the food insecurity in sub-Saharan Africa. The objectives of this study were to determine the inheritance of resistance for FAW, identity hybrids which in addition to FAW resistance, also show resistance to TLB and GLS, and investigate the usefulness of models based on general combining ability (GCA) and SNP markers in predicting the performance of new untested hybrids. Half-diallel mating scheme was used to generate 105 F1 hybrids from 15 parents and another 55 F1 hybrids from 11 parents. These were evaluated in two experiments, each with commercial checks in multiple locations under FAW artificial infestation and optimum management in Kenya. Under artificial FAW infestation, significant mean squares among hybrids and hybrids x environment were observed for most traits in both experiments, including at least one of the three assessments carried out for foliar damage caused by FAW. Interaction of GCA x environment and specific combining ability (SCA) x environment interactions were significant for all traits under FAW infestation and optimal conditions. Moderate to high heritability estimates were observed for GY under both management conditions. Correlation between GY and two of the three scorings (one and three weeks after infestation) for foliar damage caused by FAW were negative (-0.27 and -0.38) and significant. Positive and significant correlation (0.84) was observed between FAW-inflicted ear damage and the percentage of rotten ears. We identified many superior-performing hybrids compared to the best commercial checks for both GY and FAW resistance associated traits. Inbred lines CML312, CML567, CML488, DTPYC9-F46-1-2-1-2, CKDHL164288, CKDHL166062, and CLRCY039 had significant and positive GCA for GY (positive) and FAW resistance-associated traits (negative). CML567 was a parent in four of the top ten hybrids under optimum and FAW conditions. Both additive and non-additive gene action were important in the inheritance of FAW resistance. Both GCA and marker-based models showed high correlation with field performance, but marker-based models exhibited considerably higher correlation. The best performing hybrids identified in this study could be used as potential single cross testers in the development of three-way FAW resistance hybrids. Overall, our results provide insights that help breeders to design effective breeding strategies to develop FAW resistant hybrids that are high yielding under FAW and optimum conditions.

Single inclusive hadron production in DIS at small x: next to leading order corrections

We calculate the one-loop corrections to single inclusive hadron production in Deep Inelastic Scattering (DIS) at small x in the forward rapidity region using the Color Glass Condensate formalism. We show that the divergent parts of the next to leading order (NLO) corrections either cancel among each other or lead to x (rapidity) evolution of the leading order (LO) dipole cross section according to the JIMWLK evolution equation and DGLAP evolution of the parton-hadron fragmentation function. The remaining finite parts constitute the NLO (αs) corrections to the LO single inclusive hadron production cross section in DIS at small x.

Abstract‘FLLA11019‐8’ (Reg. no. CV‐386, PI 700040) is new facultative oat (Avena sativa L.) cultivar for the southern United States for forage, grain, cover, and wildlife food crop uses. It was co‐developed by the University of Florida and Louisiana State University Agricultural Center and was released in 2020 under the SunGrains, a cooperative small grain breeding program among seven Southern Universities. This line was derived from a single cross between two advanced breeding lines, FL0564‐Ab13 and LA06071SBSB‐S1. Exclusive marketing rights were granted to Ragan &amp; Massey, Inc., and the line is currently commercializing under the names of RAM Forage Oats and PlotSpike Forage Oats. The University of Florida is the lead institution in this release. FLLA11019‐8 (originally named FLLA11‐19S‐8) was developed using the selected bulk breeding method and was selected as an F5:6 head row. The line was evaluated in observation, preliminary, advanced, regional, and state grain and forage yield trials from 2016 to 2021. FLLA11019‐8 was released based on the merits of its broad adaptation, excellent grain yield, volume weight, forage potential, and winter survival. It is resistant to crown rust and stem rust and moderately resistant to Barley yellow dwarf virus. It is a mid‐maturing and mid‐tall height variety. FLLA11019‐8 has semi‐prostrate plant type with vigorous early‐season growth and high tillering capacity. It has performed very well in both grain and forage trials and is broadly adapted to the southern and southeastern United States.

Cercetări privind crearea liniilor consangvinizate și a hibrizilor de porumb timpuriu

The paper presents the synthesis of multiannual investigations concerning the development of inbred lines and early maize hybrids. 2874 sources were used over the period 1981-2020 for inbreeding and phenotypical selection, out of which 532 constant families were selected and were subject to preliminary assessment in terms of their production capacity, then transferred to the operational collection. The consequent testing resulted in the selection of 36 original lines used as parents of registered hybrids. At present, the related crosses – 56,7%, single cross hybrids – 31,6%, backcrosses – 11,4% and foreign hybrids – 0,3% are used as sources of initial material. The germplasm of alternative heterotic groups Reid Iodent – 40,1%, Euroflint – 28,9%, BSSS-B37 – 12,6%, Lancaster – 11,6%, Dent mixt – 4,0% and Dent canadian – 2,8% predominates in the lines’ pedigree. The heterotic patterns Reid Iodent x Euroflint and Reid Iodent x BSSS-B37 are mostly used for hybrid development. The production of commercial seeds for export is assured by 9 registered hybrids FAO 160-240 registered in Belarus. The hybrids Porumbeni 310, Porumbeni 305 and Alimentar 325 are used for cultivation in the Republic of Moldova.

Inheritance of growth habit in einkorn wheat

Aim. Find out the inheritance patterns of the trait “winterness / springness” in hybrids between representatives of einkorn wheat species. Methods. Crossings were carried out using the “single cross” method. The nature of inheritance of the growth habit was determined using hybridological analysis. Results. It has been shown that in the hybrids of wild wheat forms T. boeoticum and T. urartu with cultivated T monococcum and T. sinskajae, the winter growth habit of wild forms dominates over the spring one of cultivated forms. Differences in “winterness / springness” phenotype between parental forms in crosses of T.monococcum var. macedonicum with T.urartu var. spontaneorubrum and T.boeoticum var. bicolor; T.sinskajae var. sinskajae with T.urartu var. spontaneorubrum and T.boeoticum var. thaoudar; T.boeoticum var. thaoudar with T.monococcum var. monococcum, T.sinskajae var. sinskajae and T.monococcum var. macedonicum; T.boeoticum var. kurbagalensense with T.sinskajae var. sinskajae and T.monococcum var. monococcum are controlled by a single gene. The difference between the two wild forms in crossing T.boeoticum var. thaoudar × T.boeoticum var. kurbagalensense is controlled by two genes. In the crosses T.boeoticum var. thaoudar with T.monococcum var. monococcum, T.sinskajae var. sinskajae and T.monococcum var. macedonicum; T.boeoticum var. kurbagalensense × T.sinskajae var. sinskajae, the parental forms also differ digenously. Conclusions. Winterness of einkorn wheat wild forms dominates over the springness of cultivated forms. The difference in the growth habit between the studied einkorn forms is due to differences in 1 – 2 pairs of genes.

Study of multinucleon knockout reactions of exotic nuclei in the region of Sn

The experimental data collected during the S515 experiment performed by the R3B collaboration at GSI/FAIR represent a great opportunity to investigate nucleon knockout reactions of exotic nuclei in the region of Sn using complete kinematics measurements. These cross sections can be used in the future to investigate the quenching in the knockout of the minority species (neutrons or protons) in nuclei far from stability. Some of the arguments put forward are the underestimation of the knockout of deeply bound nucleons, final state interactions or the role of short-range correlations (SRC). Recently, several works based on inclusive measurements have shown that these SRCs could reduce the single nucleon knockout cross sections by around 50%, depending on the neutron excess (N/Z) of the initial projectile. The S515 data can help us to go further in this investigation because it allows to correlate the knockout cross sections of one, two or more nucleons with the number of protons and neutrons emitted from the target and which can be detected by the CALIFA and NeuLAND detectors, respectively, and perform complete kinematical studies on the nature of the event (SRC, evaporation, emission of clusters, final-state interactions...). Here the results obtained for the charge distribution of reaction residues are presented, which is one of the first steps of the still on-going analysis.

Modeling of heat transfer in tool grinding for multiscale simulations

Tool grinding is a fundamental process step when manufacturing cylindrical cemented carbide tools. A deeper understanding of the relationship between heat generation, heat transfer and fluid dynamics is essential to optimize the application of cooling lubrication. Due to the porous structure of the grinding tool as well as the rough surfaces of tool and workpiece, this inherently leads to multiscale problems. In this paper, an approach for modeling the heat transfer between the grinding tool, the workpiece and coolant on the microscale and mesoscale is introduced, including the effective influence of the porous structure. As a basis for the simulations, experimental investigations are conducted using individual abrasive grains. A linear relationship between the single grain chip cross section and the tangential force is established with an average RMSE of 1.421 N, allowing the total heat flux to be calculated. The results are then transferred to continuous and discontinuous 2D multiscale fluid dynamic simulations in order to predict heat generation and to potentially optimize the cooling lubrication in grinding processes.
