Effect of age and sexual condition on the fatty acid profile of intramuscular fat of cattle finished in feedlot

The objective of this study was to evaluate the fatty acid (FA) profile of intramuscular fat of cattle of two categories (16 or 26 months old) and two sexual conditions (Bulls or Steers) finished in feedlot. A total of 32 castrated (n=16) or noncastrated (n=16) animals of the genetic groups ½Purunã + ½Canchim were used. The animals were finished in feedlot, receiving a diet with 50% roughage and 50% concentrated feed. After the slaughter, one Longissimus dorsi sample from each animal was sent to the laboratory for FA profile analyses. The FA content of C17:0 iso and C18:0 was higher for animals slaughtered at 26 months. Lignoceric acid (C24:0) showed a higher content for animals aged 16 months. Animals slaughtered at 16 months showed higher C18:1 cis 11, C18:1 cis 12, C18:1 cis 15, and lower C18:1 trans 16 than those slaughtered at 26 months. The C20:4 and C22:5 were lower as the animals' slaughter age increased. The unsaturated/saturated and polyunsaturated/saturated ratios showed no difference for slaughter age. The concentrations of C24:0, C18:1 trans 10, C18:1 cis 11, C18:1 cis 12, and C22:1 were greater in the meat of bulls than in steers. Bulls had a higher content of polyunsaturated FAs and polyunsaturated/saturated ratio than steers.

A Conceptual Approach to the Formation of an Intelligent Digital Innovation Economy

This paper analyzes the essence of the conceptual approach to the intellectual digital innovation economy, which will be formed based on the normal development of the digital economy. It is noted that most researchers of the economy of the modern era use many different concepts such as knowledge, digital, Internet, post-industrial, virtual, network, information, electronic, intellectual, etc. in their works. Scientific approaches to the study of the development problems of the intellectual economy formed in the new era are classified. As a result of summarizing existing scientific works, a new approach to the system of economic relations using modern innovative information technologies, the intellectual information environment efficiently developed with ICT, and the newly formed intellectual digital innovation economy are proposed. With the help of digital technologies, priority directions for developing information infrastructure, and Global digital space, including new business models, have been proposed. By using the concept of Industry 4.0 and "smart structures" as the driving force of the digital transformation of industrial development, taking advantage of the use of the "cyber-physical system" as a unified complex of information resources, systems, and physical processes and the Internet of Things, cloud, Big Data, artificial intelligence technologies, new recommendations on the formation of the economy were given.
The Financial Indicators of TMR Monitoring on Dairy Farms in Hungary, as Part of Quality Assurance Tools

The TMR (total mixed ration) technology is one of the most sufficient feeding methods on the dairy farms. From a quality assurance and technological point of view, regular TMR testing is of paramount importance to reduce the risk and extent of milk production losses and animal health problems. The goal was to find out how popular the TMR monitoring in Hungary is, and find out, how much it may cost for a dairy farm in a year. In the course of our investigations, we assessed the economic indicators of TMR samples received by the NIR Forage Laboratory of Livestock Performance Testing Ltd. between 2013 and 2021, especially the distribution and size of costs per farm and per cow. Our aim was to be able to draw conclusions about the application rates, the total and relative costs of TMR analyses according to the farm size. The proportion of farms requesting TMR examinations was higher for farms with a larger number of animals (501-1000 cows inspected). Within the category, the highest TMR sample submission rate was found for the farms with 501-600 and 801-1000 cows inspected. The average monthly total TMR laboratory cost per site was extremely low in the period of 2013-2021 (HUF 3,000-10,000 /month/farm) compared to the risk and potential loss. The relative TMR cost of farms with more than 701 cows inspected was rather low (HUF 6-9 / inspected cow / month) in terms of screening for technological errors, risk of loss and quality assurance. This indicates that there is great potential for quality assurance in TMR studies at sites and that this potential is not currently being exploited.
Comparison and Validation of Five Modulation Strategies for a Dual Active Bridge Converter

This paper addresses the comparison and validation of different modulations for an isolated dc-dc dual active bridge converter (DAB), namely, Duty-Cycle Modulation, Single Phase Shift (SPS), Dual Phase Shift (DPS), Extended Phase Shift (EPS) and Triple Phase Shift (TPS). Given the DAB’s applicability in a wide variety of power electronics branches, several control strategies are being studied to improve its efficiency, by mitigating circulating currents and reactive power. Regardless of the chosen architecture, appropriate modulations must be adopted, assessing which one presents the better cost-benefit ratio. This simulation-based analysis aims to investigate the DAB performance when controlled by the above-mentioned modulations and operating with a nominal power of 3.6 kW. Thus, simulation results show that only SPS, DPS, and TPS are considered suitable, while Duty-Cycle Modulation has time limitations during power transfer and EPS is more appropriate for dynamic power applications.
Transitional flight equilibrium and performance study for the X-NMRL tail-sitter VTOL MAV

An investigation on transitional flight equilibrium, performance analysis and parameter impacts is conducted in a conversion corridor, based on the proposed X-NMRL tail-sitter Vertical Takeoff and Landing Micro Air Vehicles (VTOL MAVs). Dependent on a propulsion model, aerodynamic model and physical control model, a nonlinear mathematical transitional model of the vehicle dynamics was constructed with consideration of the velocity, angle of attack, thrust, control surface deflection and pitching angle. The momentum theory and estimation method are applied to simulated propeller slipstream effects on aerodynamics, and an aerodynamic model for all regions of angles of attack and velocities is built. The nonlinear indefinite high-order dynamic model is solved by the improved Newton iteration algorithm. The corridor of the pitching angle or flight-path angle to the velocity reveals that the boundaries are mainly governed by the stalling performance, full throttle thrust and zero thrust, respectively. The performance corridor indicates different performance parameter variations under different conditions of steady climbing, cruising and descending states. Additionally, the performance for a steady transitional strategy can be illustrated to some extent. In terms of the parameter impacts, the increasing max propulsive power, supplied voltage, and decreasing total weight can widen the transitional corridor effectively, and the changes in the aerodynamics will only move the boundaries toward the same direction. These results will benefit transitional vehicle designs and control designs.
Sensitive Quantitative In Vivo Assay for Evaluating the Effects of Biomolecules on Hair Growth and Coloring Using Direct Microinjections into Mouse Whisker Follicles

Many people suffer from hair loss and abnormal skin pigmentation, highlighting the need for simple assays to support drug discovery research. Current assays have various limitations, such as being in vitro only, not sensitive enough, or unquantifiable. We took advantage of the bilateral symmetry and large size of mouse whisker follicles to develop a novel in vivo assay called “whisker follicle microinjection assay”. In this assay, we plucked mouse whiskers and then injected molecules directly into one side of the whisker follicles using microneedles that were a similar size to the whiskers, and we injected solvent on the other side as a control. Once the whiskers grew out again, we quantitatively measured their length and color intensity to evaluate the effects of the molecules on hair growth and coloring. Several chemicals and proteins were used to test this assay. The chemicals minoxidil and ruxolitinib, as well as the protein RSPO1, promoted hair growth. The effect of the clinical drug minoxidil could be detected at a concentration as low as 0.001%. The chemical deoxyarbutin inhibited melanin production. The protein Nbl1 was identified as a novel hair-growth inhibitor. In conclusion, we successfully established a sensitive and quantitative in vivo assay to evaluate the effects of chemicals and proteins on hair growth and coloring and identified a novel regulator by using this assay. This whisker follicle microinjection assay will be useful when investigating protein functions and when developing drugs to treat hair loss and abnormal skin pigmentation.
Graph Embedding Techniques for Predicting Missing Links in Biological Networks: An Empirical Evaluation

Network science tries to understand the complex relationships among entities or actors of a system through graph formalism. For instance, biological networks represent macromolecules such as genes, proteins, or other small chemicals as nodes and the interactions among the molecules as links or edges. Often potential links are guessed computationally due to the expensive nature of wet lab experiments. Conventional link prediction techniques rely on local network topology and fail to incorporate the global structure fully. Graph representation learning (or embedding) aims to describe the properties of the entire graph by optimized, structure-preserving encoding of nodes or entire (sub) graphs into lower-dimensional vectors. Leveraging the encoded vectors as a feature improves the performance of the missing link identification task. Assessing the predictive quality of graph embedding techniques in missing link identification is essential. In this work, we evaluate the performance of ten (10) state-of-the-art graph embedding techniques in predicting missing links with special emphasis on homogeneous and heterogeneous biological networks. Most available graph embedding techniques cannot be used directly for link prediction. Hence, we use the latent representation of the network produced by the candidate techniques and reconstruct the network using various similarity and kernel functions. We evaluate nine (09) similarity functions in combination with candidate embedding techniques. We compare embedding techniques’ performance against five (05) traditional (non-embedding-based) link prediction techniques. Experimental results reveal that the quality of embedding-based link prediction is better than its counterpart. Among them, Neural Network-based embedding and attention-based techniques show consistent performance. We even observe that dot-product-based similarity is the best in inferring pair-wise edges among the nodes from their embedding. We report interesting findings that while predicting links in the heterogeneous graph, it predicts a good number of valid links between corresponding homogeneous nodes due to the possible indirect effect of homogeneous-heterogeneous interactions.
Translation and cross-cultural adaptation of the Noise Exposure Questionnaire (NEQ) to Brazilian Portuguese

ABSTRACT Objective To translate and cross-culturally adapt the Noise Exposure Questionnaire (NEQ) and 1-Minute Noise Screen (NEQ-S) instruments to Brazilian Portuguese. Methods Procedures widely known in health research were used in the translation and cross-cultural adaptation process, comprising the following steps: initial translation, synthesis of translations, back-translation, expert committee, pretest, and content and layout validation. Altogether, 60 workers participated in the pretest by answering the questionnaires and then evaluating them in terms of understandability, layout, clarity, and writing. Reliability was verified with Cohen's kappa test, and the internal consistency was analyzed with Cronbach’s alpha coefficient. Results The translated and adapted versions of NEQ and NEQ-S were similar in terms of general and referential meanings. However, some modifications and adaptations were made to adapt them to the Brazilian reality. The kappa test indicated moderate agreement and Cronbach’s alpha coefficient, substantial internal consistency. Conclusion The translation and cross-cultural adaptation were carried out according to the methodology recommended in the national and international literature, performing the necessary equivalences to maintain the face and content validity with the original instrument. The availability of NEQ and NEQ-S in Brazilian Portuguese opens new fields of research to quantify yearly noise exposure more in-depth.
Correspondences and their Action on Filtrations on Cohomology and 0-cycles of Abelian Varieties

We prove that, given a symmetrically distinguished correspondence of a suitable abelian variety (in particular any abelian variety of dimension atmost 5 over an algebraically closed field $k\subset\mathbf{C}$), which vanishes on a certain quotient of its middle singular cohomology, then it vanishes as a morphism on the deepest part of a particular filtration on the Chow group of 0-cycles of the abelian variety. As a consequence, we prove that given an automorphism of such an abelian variety, which acts as Identity on a certain quotient of its middle singular cohomology, then it acts as Identity on the deepest part of this filtration on the Chow group of 0-cycles of the abelian variety. We further use this to prove that for the Generalized Kummer variety associated to a complex abelian surface and the automorphism induced from a symplectic automorphism of the complex abelian surface, the automorphism of the Generalized Kummer variety acts as Identity on its Chow group of 0-cycles.

Reflection and transmission of obliquely incident light by chiral sculptured thin films fabricated using asymmetric serial-bideposition technique

Abstract. Chiral sculptured thin films (STFs) were grown using the asymmetric serial-bideposition (ASBD) technique, whereby (i) two subdeposits of unequal heights are separated by a substrate rotation of 180 deg about the central normal axis, and (ii) consecutive subdeposit pairs are separated by a small substrate rotation δ on the order of a few degrees. Eight samples were prepared with subdeposit heights in ratios of 1:1, 1.5:1, 2:1, 2.5:1, 3:1, 5:1, 7:1, and 9:1. A finely ambichiral STF was also grown. All nine samples were grown with the same vapor flux direction and to have 10 periods with the same thickness. The spectrums of all eight circular remittances of every sample were measured over a wide range of incidence angle θinc. Redshifting and narrowing of the circular Bragg regime was observed with increasing subdeposit-height ratio for all values of θinc, arriving at a limit with the 9:1 sample. The finely ambichiral sample has a circular Bragg regime similar to that of the 9:1 sample, but the latter exhibits much better discrimination between incident left circularly polarized light and right circularly polarized light than the former for θinc larger than about 20 deg.
A multi‐level adaptive mesh refinement method for level set simulations of multiphase flow on unstructured meshes

An adaptive mesh refinement (AMR) technique is proposed for level set simulations of incompressible multiphase flows. The present AMR technique is implemented for two‐dimensional/three‐dimensional unstructured meshes and extended to multi‐level refinement. Smooth variation of the element size is guaranteed near the interface region with the use of multi‐level refinement. A Courant–Friedrich–Lewy condition for zone adaption frequency is newly introduced to obtain a mass‐conservative solution of incompressible multiphase flows. Finite elements around the interface are dynamically refined using the classical element subdivision method. Accordingly, finite element method is employed to solve the problems governed by the incompressible Navier–Stokes equations, using the level set method for dynamically updated meshes. The accuracy of the adaptive solutions is found to be comparable with that of non‐adaptive solutions only if a similar mesh resolution near the interface is provided. Because of the substantial reduction in the total number of nodes, the adaptive simulations with two‐level refinement used to solve the incompressible Navier–Stokes equations with a free surface are about four times faster than the non‐adaptive ones. Further, the overhead of the present AMR procedure is found to be very small, as compared with the total CPU time for an adaptive simulation. Copyright © 2016 John Wiley & Sons, Ltd.
Complex intuitionistic fuzzy group

The aim of this study is to introduce the notion of complex intuitionistic fuzzy groups based on the notion of complex intuitionistic fuzzy space this concept generaleis the concept of intuitionistic fuzzy space from the real range of membership function and non-membership[0,1] , to complex range of membership function and, non-membership unit disc in the complex plane. This generalization leads us to introduce and study the approach of intuitionistic fuzzy group theory that studied by Fathi (2009) in the realm of complex numbers. In this paper, a new theory of complex intuitionistic fuzzy group is developed. Also, some notions, definitions and examples related to intuitionistic fuzzy group are generalized to the realm of complex numbers. Also a relation between complex intuitionistic fuzzy groups and classical intuitionistic fuzzy subgroups is obtained and studied.
Novel Highly Efficient Antibacterial Chitosan-Based Films

In this study, we elaborated new chitosan-based films reinforced by iron(III)-containing chitosan nanoparticles Fe(III)-CS-NPs at different concentrations. We found that the optimum concentration of Fe(III)-CS-NPs for the improvement of antibacterial and mechanical properties of the films was 10% (σb = ca. 8.8 N/mm2, εb = ca. 41%, inhibition zone for S. aureus = ca. 16.8 mm and for E. coli = ca. 11.2 mm). Also, using the click-chemistry approach (thiol–ene reaction), we have synthesized a novel water-soluble cationic derivative of chitin. The addition of this derivative of chitin to the chitosan polymer matrix of the elaborated film significantly improved its mechanical (σb = ca. 11.6 N/mm2, εb = ca. 75%) and antimicrobial (inhibition zone for S. aureus = ca. 19.6 mm and for E. coli = ca. 14.2 mm) properties. The key mechanism of the antibacterial action of the obtained films is the disruption of the membranes of bacterial cells. The elaborated antibacterial films are of interest for potential biomedical and food applications.

Guideline-Adherent Hypertension in Children and Adolescents: A Multi-Institutional Database Analysis from Taiwan

Background/Aims: Childhood-onset hypertension is associated with cardiovascular morbidity and adult mortality. This study aimed to assess guideline-adherent hypertension among Taiwanese youth and the agreement on hypertension between the 2017 American Academy of Pediatrics guidelines and the 2004 Fourth Report. Methods: In this cross-sectional study, we collected outpatient blood pressure (OBP) measurements obtained during routine care visits from a large healthcare delivery system between 2009 and 2018 to evaluate the rate of guideline-adherent hypertension and assess patient-related factors of pediatric hypertension. Results: In total, 12,469 children and adolescents who underwent three separate ≥3 OBP measurements over 33,369 person-years with a total of 95,608 BP measurements in an outpatient setting were analyzed. According to the 2017 American Academy of Pediatrics (AAP) guidelines, the rate of pediatric hypertension in the study setting, which included participants aged 1 to 17 years, ranged from 0.78 to 5.95 per 1000 persons. Although there was perfect agreement between the thresholds of the two guidelines for defining hypertension in the age groups of 1–7, 8–12, and 13–17 years (all κ statistic ≥ 0.85), the use of the AAP threshold classified more adolescents as having hypertension. Children and adolescents with hypertension often had complex chronic diseases and required substantial healthcare services in outpatient, emergency, and inpatient settings. Conclusions: The present study provides evidence of guideline-adherent pediatric hypertension and highlights the importance of regularly monitoring blood pressure to identify and manage hypertension in children and adolescents. Further research is required to determine the impact of new thresholds on the detection of target organ damage at a pediatric age.
