Abstract
Background: Although Oxford unicompartmental knee arthroplasty (UKA) is used in patients of wide age ranges, there is no clear information regarding the age differences in terms of intraoperative femorotibial rotational kinematics and its influence on clinical outcomes. Therefore, this study was conducted to examine the age differences in terms of postoperative clinical outcomes and intraoperative rotational kinematics and to analyze their relationship with classification according to the age group.Methods: We investigated 111 knees of patients who underwent Oxford UKA using a navigation system and divided them into two groups: elderly (aged ≥75 years; 48 knees) and nonelderly (aged <75 years; 63 knees). Intraoperative tibial internal rotational angles relative to the femur during passive knee flexion were measured using a navigation system, and clinical outcomes were evaluated using knee range of motion, the Knee Injury and Osteoarthritis Outcome Score (KOOS), and the Knee Society Functional Score at 2 years postoperatively. The relationships between intraoperative tibiofemoral rotational angles and clinical outcomes were also evaluated in the two groups. Results: The intraoperative tibial internal rotational angle relative to the femur during knee flexion was significantly larger in the nonelderly group (13.5°) than in the elderly group (9.0°). The intraoperative tibial internal rotational angle showed a positive correlation with the pain subscale of KOOS only in the nonelderly group. Conclusion: Intraoperative rotational kinematics and its influence on clinical outcomes were different between elderly and nonelderly patients, and the tibial internal rotational angle could be a more important factor for successful UKA in nonelderly patients.

Abstract
This study aimed to investigate the incidence of and risk factors for postoperative new-onset deep venous thrombosis (PNO-DVT) following intertrochanteric fracture surgery. Information on 1672 patients who underwent intertrochanteric fracture surgery at our hospital between January 2016 and December 2019 was extracted from a prospective hip fracture database. Demographic information, surgical data, and preoperative laboratory indices were analyzed. Receiver operating characteristic curve analysis, univariate analyses and binary logistic regression analyses were performed. The incidences of postoperative deep venous thrombosis (DVT) and PNO-DVT in inpatients after intertrochanteric fracture surgery were 11.5% (202 of 1751 patients) and 7.4% (123 of 1672 patients), respectively. The PNO-DVT accounted for 60.9% of the postoperative DVT. Additionally, there were 20 cases of central thrombosis (16.3%), 82 cases of peripheral thrombosis (66.7%), and 21 cases of mixed thrombosis (17.1%). And, 82.1% of DVTs were diagnosed within 8 days after surgery. The multivariate analysis revealed that age > 70 years, duration of surgery (> 197 mins), type of anesthesia (general), and comorbidities (≥ 3) were independent risk factors for the development of PNO-DVT after intertrochanteric fracture surgery. This study demonstrated a high incidence of PNO-DVT in inpatients after intertrochanteric fracture surgery. Therefore, postoperative examination for DVT should be routinely conducted for patients.

Abstract
Controversy exists regarding whether the rate of hepatocellular carcinoma (HCC) recurrence after orthotopic liver transplantation (OLT) differs when using livers from donation after controlled circulatory death (DCD) versus livers from donation after brain death (DBD). The aim of this cohort study was to analyze rates of HCC recurrence, patient survival, and graft survival after OLT for HCC, comparing recipients of DBD livers (n=103) with recipients of uncontrolled DCD livers (uDCD; n=41). No significant differences in tumor size, tumor number, serum alpha-fetoprotein, proportion of patients within Milan criteria, or pre-OLT bridging therapies were identified between groups, although the waitlist period was significantly shorter in the uDCD group (p=0.04). HCC recurrence was similar between groups. Patient survival was similar between groups, but graft survival was lower in the uDCD group. Multivariate analysis identified recipient age (p=0.03), pre-OLT bridging therapy (p=0.02), and HCC recurrence (p=0.04) as independent risk factors for patient survival and pre-OLT transarterial chemoembolization (p=0.04) as the single risk factor for HCC recurrence. In conclusion, similar patient survival and lower graft survival were observed in the uDCD group. However, the use of uDCD livers appears to be justified due to shorter waitlist time and similar HCC recurrence in both groups.

Abstract
Background: Rice is one of the most important grain crops worldwide. The accurate and dynamic monitoring of leaf are index (LAI) provides important information to evaluate rice growth and production. Methods: This study explores a simple method to remotely estimate LAI with Unmanned Aerial Vehicle (UAV) imaging for a variety of rice cultivars throughout the entire growing season. 48 different rice cultivars were planted in the study site and field campaigns were conducted once a week. For each campaign, several widely used vegetation indices (VI) were calculated from canopy reflectance obtained by 12-band UAV images, canopy height was derived from UAV RGB images and LAI was destructively measured by plant sampling. Results: The results showed the correlation of VI and LAI in rice throughout the entire growing season was weak, and for all tested indices there existed significant hysteresis of VI vs. LAI relationship between rice pre-heading and post-heading stages. The model based on the product of VI and canopy height could reduce such hysteresis and estimate rice LAI of the whole season with estimation errors under 24%, not requiring algorithm re-parameterization for different phenology stages. Conclusions: The progressing phenology can affect VI vs. LAI relationship in crops, especially for rice having quite different canopy spectra and structure after its panicle exsertion. Thus the models solely using VI to estimate rice LAI are phenology-specific and have high uncertainties for post-heading stages. The model developed in this study combines both remotely sensed canopy height and VI information, considerably improving rice LAI estimation accuracy at both pre- and post-heading stages. This method can be easily and efficiently implemented in UAV platforms for various rice cultivars during the entire growing season with no rice phenology and cultivar pre-knowledge, which has great potential for assisting rice breeding and field management studies at a large scale.

Abstract
Stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is one of the most damaging diseases of wheat globally and resistance is the effectively control strategy. Triticum boeoticum Boiss (T. monococcum L. ssp. aegilopoides, 2n = 2x = 14, AbAb) accession G52 confers a high level of adult-plant resistance against a mixture of the Chinese prevalent Pst races. To transfer the resistance to common wheat, a cross was made between G52 and susceptible common wheat genotype Crocus. A highly resistant wheat-T. boeoticum introgression line Z15-1370 (F5 generation) with 42 chromosomes was selected cytologically and by testing with Pst races. In order to map the resistance gene(s), F1, F2, and F2:3 generations of the cross between Z15-1370 and stripe rust susceptible common wheat Mingxian169 were developed. Genetic analysis revealed that the resistance in Z15-1370 was controlled by a single recessive gene, temporarily designated YrZ15-1370. Using the bulked segregant RNA-Seq (BSR-Seq) analysis, YrZ15-1370 was mapped to chromosome 6AL and flanked by markers KASP1370-3 and KASP-1370-5 within a 4.3 cM genetic interval corresponding to 1.8 Mb physical region in the Chinese Spring genome, in which a number of disease resistance-related genes were annotated. YrZ15-1370 differed from previously Yr genes identified on chromosome 6A based on its position and/or origin. The YrZ15-1370 would be a valuable resource for wheat resistance improvement and the flanking markers developed here should be useful tools for marker-assisted selection (MAS) in breeding and further cloning the gene.

Abstract
We show, by single-crystal diffraction studies in laser-heated diamond-anvil cells, that Ca2CO4 orthocarbonate, which contains CO44− tetrahedra, can be formed already at ~20 GPa at ~1830 K, i.e., at much lower pressures than other carbonates with sp3-hybridized carbon. Ca2CO4 can also be formed at ~89 GPa and ~2500 K. This very broad P-T range suggests the possible existence of Ca2CO4 in the Earth’s transition zone and in most of the lower mantle. Raman spectroscopy shows the typical bands associated with tetrahedral CO44−-groups. DFT-theory based calculations reproduce the experimental Raman spectra and indicate that at least in the athermal limit the phase assemblage of Ca2CO4 + 2SiO2 is more stable than 2CaSiO3 + CO2 at high pressures.

Published: March 2021

Abstract
This paper presents a fast simulation model for predicting the dynamic response of a motor-pump system to startup event. The purpose is to analyze the effect of the impeller acceleration time, the final flow rate and the impeller geometry on the pump transient flow during starting operations. The motor speed and torque variations were predicted by simulating the transient law of the three-phase induction motor by adopting the d-q axes theory. The pump model was built by solving the unsteady flow governing equations with the method of characteristics (MOC). The whole model was validated with available tests from literature. Accordingly, the computation of impeller acceleration, the motor torque, the unsteady pressure and flow rate was made for various starting conditions. The results have revealed that during its starting time, the pump hydraulic transients are well influenced by the motor speed acceleration, the flow inertia and the impeller geometry. Through the analysis of the simulation results, the conclusion was that the accuracy of the present method is reasonable, and it can be used for assisting pumping system design.
Effects of a Rehabilitation Program Using a Patient-Personalized Exergame on Fear of Falling and Risk of Falls in Vulnerable Older Adults: Protocol for a Randomized Controlled Group Study
Authors: Lapierre Nolwenn , Um Din Nathavy , Igout Manuella , Chevrier Joël , Belmin Joël 
Published: March 2021

Background
Older adults often experience physical, sensory, and cognitive decline. Therefore, they have a high risk of falls, which leads to severe health and psychological consequences and can induce fear of falling. Rehabilitation programs using exergames to prevent falls are being increasingly studied. Medimoov is a movement-based patient-personalized exergame for rehabilitation in older adults. A preliminary study showed that its use may influence functional ability and motivation. Most existing studies that evaluate the use of exergames do not involve an appropriate control group and do not focus on patient-personalized exergames.

Objective
This study aims to evaluate the effects of Medimoov on risk of falls and fear of falling in older adults compared with standard psychomotor rehabilitation.

Methods
This is a serial, comparative, randomized controlled group study. Both groups (n=25 in each) will receive psychomotor rehabilitation care. However, the methods of delivery will be different; one group will be exposed to the Medimoov exergame platform, and the other only to traditional means of psychomotor rehabilitation. The selection criteria will be (1) age of 65 years or older, (2) ability to answer a questionnaire, (3) ability to stand in a bipedal position for at least 1 minute, (4) score of 13 or greater on the Short Fall Efficacy Scale, and (5) stable medical condition. An evaluation will be made prior to starting the intervention, after 4 weeks of intervention, and at the end of the intervention (after 8 weeks), and it will focus on (1) risk of falls, (2) fear of falling, and (3) cognitive evaluations. Physical activity outside the session will also be assessed by actimetry. The outcome assessment will be performed according to intention-to-treat analysis.

Results
The protocol (2019-11-22) has been approved by the Comité de Protection des Personnes Nord-Ouest I–Université de Rouen (2019-A00395-52), which is part of the French national ethical committee. The study received funding in February 2020. As of October 2020 (submission date), and due to the context of the COVID-19 pandemic, a total of 10 participants out of 50 had been enrolled in the study. The projected date for the end of the data collection is December 2021. Data analyses have not been started yet, and publication of the results is expected for Spring 2022.

Conclusions
The effects of psychomotor rehabilitation using the Medimoov exergame platform on the risk and fear of falls will be evaluated. This pilot study will be the basis for larger trials.

Authors: Lima Marcos Salmo S. , Fiss Dóris Maria Luzzardi 
Published: March 2021

Este artigo tem como objetivo descrever uma proposta didático-pedagógica, voltada para a Educação Básica, que envolve estudo sobre a Região Amazônica a partir da música regional, levando em consideração o entendimento de gênero discursivo como artefato mediador de aprendizagem. A temática se mostra relevante para o ensino pelo compromisso assumido com a criação de condições de constituição de um sujeito social mais crítico e reflexivo, respeitando as diferenças culturais existentes no território brasileiro e preservando o meio em que vive. Escolhemos trabalhar a música regional por ela estar mais próxima da realidade do educando e se configurar como elemento de desenvolvimento de habilidades e competências tanto no nível linguístico quanto no discursivo. Desde uma filiação a concepções do filósofo russo Mikhail Bakhtin, buscamos subsídios em sua teoria dialógica, que tem no conceito de gênero do discurso uma contribuição significativa para a prática em sala de aula.

“The Case… of the Danilevsky Family Nobility”: Dates and Mysteries of Birth
Authors: Zhuravel Alexander V. 
Published: March 2021

On the basis of the sources available today the article examines a number of issues related to the history of the Danilevsky family and shows the new possible directions of the searches. The study specifies the dates of birth of N.Ya. Danilevsky and his father, Major General Ya. I. Danilevsky. The life path of his father determined on the basis of the “Case... of the Danilevsky Family Nobility” (1834), allows us to better understand the conditions of the childhood of the future scientist and thinker. It turns out that the Mishin family, the nobles of Livny, specifically brothers of his mother, provided substantial, versatile assistance to the Danilevsky family. Finally, the question of the origin of the Danilevsky family is examined. Although it has not yet been possible to establish the lost connection between generations, data has been found about previously unknown relatives of the founder of the clan, sotnik, and then the judge of the Izyum Cossack Regiment Danila Danilovich Danilevsky (c. 1649–1719) – about brother Lukash Danilev, son Mikhail and some other persons... This opens new avenues for further genealogical research.

The article is devoted to the understanding of N.Ya. Danilevsky’s historiosophical concept in the context of the results and prospects of researching the history of Russian philosophy. The article substantiates the thesis about the significance of Russian thought, which developed in the 19th – early 20th century the methodological approach based on the principles of lax systematization, rejection of extremes and content completeness. The author brings forward the problem of insufficient research into the hidden influence of Russian thought on Western philosophy of the non-classical period by comparing the philosophical and historical views of N.Ya. Danilevsky and O. Spengler. The author states his vision of the goals and results of further research work of the community of Russian philosophy historians in the context of the deep crisis of modern Western philosophy, which has not only theoretical, but also practical orientation, associated with the actu
Cyclism as the Core Idea of Russian Thought in the Second Half of the 19th and the Beginning of the 20th Centuries
Authors: Mochshelkov Evgeny N. 
Published: March 2021

The article examines the ideas and concepts of the cyclic development of human thought and history, which were developed by Russian thinkers in their works in the second half of the 19th and early 20th centuries. The author shows that in the said period of domestic thought development the cyclic worldview spread in the most important spheres of humanitarian knowledge: philosophy and political teachings (B.N. Chicherin, 1826–1904), social theory and sociology (N.Ya. Danilevsky, 1822–1885) and K.N. Leontiev, 1831–1891), and finally, the theory of cycles (waves) in world socio-economic dynamics (N.D. Kondratyev, 1892–1938). Thus, Russian thinkers laid the conceptual foundations of the original cyclic paradigm of social dynamics, which later were further developed by a number of Western scientists (O. Spengler, 1880–1936; A.J. Toynbee, 1889–1975, etc.).

This study examined the effect of the application of games on students' interest and learning in volleyball lessons. Two experienced secondary physical education teachers involved in the Secondary Teaching Evaluation and Mentoring Project (STEM) were purposely invited to take part in the study. They were trained with the skills and knowledge of mentorship as well as the application of variation theory in designing lessons for learning. The study was premised on a conceptual framework of variation theory and employed an action research methodology. The study lessons were taught in three cycles by the two teachers to three S. 2 classes of students in their own schools. Games were specially adopted to address the students’ interest and learning in the lessons. Pre and post conferences were arranged for reviewing and improving the effectiveness of the lessons. Questionnaire and a volleyball skill test were developed to evaluate the student perception and learning in the lessons. The results revealed that there was an increase in the number of students showing interest in participating in volleyball lessons as well as the students had improved significantly in the application of volley pass skill. Findings of the present study hold implications of the instructional practice for physical educators.
