Forces in Axial Flux Magnetic Gears with Integer and Fractional Gear Ratios

This paper presents a comparison of two variants of an axial flux magnetic gear (AFMG), namely, with integer and fractional gear ratios. Based on calculations derived with the use of three-dimensional numerical models, the torque characteristics of the analyzed AFMGs are computed and verified on a physical model. The greatest emphasis is put on the detailed decomposition and analysis of local forces in modulator pole pieces (also used in the structural analysis) within the no-load and maximal load conditions. The authors also describe the unbalanced magnetic forces (UMF) in the axial and radial directions resulting from the construction of the considered AFMGs variants, and their possible effects in the context of the use of additive manufacturing (AM) in prototypes. The paper also proposes an effective method for limiting the axial strain by using the asymmetry of the air gaps, which slightly reduces the torque transmitted by AFMGs. Finally, a static strength analysis was presented that allows us to assess the effects of local forces in the form of modulator disc deformation for selected cases of air gap asymmetry.
A Comparison of Machine Learning Algorithms for Automatic Cloud Resource Scaling on a Multi-Tenant Platform

In an online multi-tenant machine learning platform, the system manager would dynamically load the computing resource according to the tenant’s demand. With cloud computing services, the platform can rent or release computing resources dynamically to fulfill tenant usage which minimizes resource consumption and ensure scalability. Currently, many cloud-based services providers are using the rule-based, threshold auto-scaling mechanism. However, the rule-based method is not efficient, as the nature of availability and cost-reducing violate each other in this method, especially with the sudden increase or variation of the demand. In this paper, we compare several machine-learning-based predictive algorithms to build models based on the information of the system used to predict future usage demands. Decisions made based on this prediction save over 80% cloud resource consumption compared to the rule-based method.

Osteocalcin: an emerging biomarker for bone turnover

Osteocalcin (OC) is produced by osteoblasts during bone formation. OC is excreted into urine by glomerular filtration and can be found as fragments in urine. The presence of three vitamin K-dependent γ-carboxyglutamic acid residues is critical for osteocalcin’s structure, which appears to regulate the maturation of bone mineral. Recent bone biology research have highlighted the importance of bone not only as a structural scaffold to support the human body, but also as a regulator of a metabolic processes that are independent of mineral metabolism. Circulating osteocalcin is present either as carboxylated or as undercarboxylated forms. Increased serum level of osteocalcin is linked with increased bone mineral density. The importance of the bone–kidney relation in physiologic regulation of mineral ion has also been extensively studied and documented. Several workers have uncovered the role of insulin as an additional factor involved in the skeletal remodelling process. Evidences are available which shows that osteoblastic insulin signalling is important for glucose metabolism. The measurement of OC in urine samples could be used as an index of bone turnover in monitoring bone metabolism. In this review, we have tried to explain different roles of OC, however further studies are required to elucidate the metabolic and hormonal role of OC in human body.
SOME RADIOCHEMICAL AND PHYSICAL MEASUREMENTS OF DEBRIS FROM AN UNDERGROUND NUCLEAR DETONATION

Fallout samples were collected from 2600 feet to 19,000 feet from ground zero in order to determine the mass per unit area, gamma activity per unit area, particle size distribution, and specific activity versus particle size of the fallout; to determine the gamma decay rate and spectra of the samples; to perform leaching and exchange studies on the radioactive debris; to measure the release of gaseous fission product iodine; and to determine the radiochemical composition of the fallout particulate. Twenty collectors (2 ft x 2 ft x 2 in. deep) were placed in the downwind sector at increasing distances. An iodine gas sampler was located approximately two miles downwind. The fallout was well distributed over the station array, and all collectors received significant deposits. Analysis of the debris was performed at the Nevada Test Site. Airborne iodine fission products were found in the contanainated field downwind from ground zero, and iodine fission products were fcund to volatilize or be otherwise released from particulate fallout. Gamma-decay measurements showed no evidence of radionuclide fractionation in debris from different locations, nor among different particle size fractions. Pulseheight distributions also indicated no significant fractionation of gamma-emitting radionuclides. A 4- pi ionization chamber decay ratemore » measurement showed excellent agreement with a computed decay rate. Measurements of mass and activity distributions indicate that the radionuclides are associated with the volume of the particle rather than with its surface area. Radiochemical data are presented, but extensive analysis was not attempted. (auth)« less
Neural Collaborative For Music Recommendation System

In music there are various types of genres and every person has their own choice of the type of music they want to hear. Recommendation system is an important feature in an application, especially with the large number of choices for a particular item. With a good recommendation system, users will be helped by the suggestions given and can improve the user experience of the application. It is better provided by using collaborative filtering (CF) approach by recommending products related to one’s preferences history. However, CF approach still lacking in integrating complex users data. Therefore, hybrid technique could be the solution to polish the CF approach. Combining neural network and CF also called NCF thought to be better than CF alone. This study focuses on collaborative filtering approach combined with neural network or called neural collaborative filtering. In this study, we use 20,000 users, 6,000 songs, and 470,000 transaction ratings then predict the score using CF and NCF approach. The aim of this study is to differentiate recommendation systems with the use of CF alone and NCF. Through this research, it was found that NCF is better than user-based collaborative filtering in gather those playlist they really want to hear, but requires more time to build it.
Demodulation of a polarization‐maintaining photonic crystal fiber load sensor with high resolution using a microwave photonic filter

A new demodulation technique for polarization‐maintaining photonic crystal fiber pressure sensor with high resolution based on a simple photonic microwave filter has been proposed and demonstrated. Unlike the conventional methods that use optical interferometry and optical spectrum analysis, the proposed method adopts microwave photonics technique. The relationship between load and the notch frequency of the filter is studied. By measuring the notch frequency of the filter, the pressure can be determined and the sensing sensitivity is greatly increased. The sensitivity is as high as 15.625 MHz/N which satisfied well with the theoretical simulation.

'What Is the Plural of Mouse?' and Other Unhelpful Questions for Morphologists

In this paper a number of questions about the morphology of English are posed, and it is shown that each of them carries presuppositions which may be theoretically unsupportable, because there is data which suggests that they are wrong. If we do not make theoretical assumptions, but let ourselves be guided by the data, our theoretical statements may have to be modified, sometimes in crucial ways. While this paper is, to the extent that it asks morphological questions, a contribution to what a morphological theory should comprise, the more general conclusion is that the way in which we frame questions that we expect our theory to answer can have implications for our findings, and that it is always worthwhile querying the content of our fundamental questions.

Anti-adherence and Anti-fungal Abilities of Thymol and Carvacrol Against Candida Species Isolated From Patients with Oral Candidiasis in Comparison with Fluconazole and Voriconazole

Background: Natural isopropyl cresols, such as thymol and carvacrol, have been known to have antifungal activities. Objectives: The current study aimed to investigate the anti-adherence and antifungal activities of thymol, carvacrol, fluconazole, and voriconazole against oral isolates of Candida albicans (C. albicans), C. glabrata, and C. krusei. Methods: The susceptibility assay for the test compounds was performed using the disk diffusion method against all Candida isolates. Also, anti-adherence activity was examined using a rapid and highly reproducible 96 well microtiter-based method. Results: Both natural phenols and antifungal drugs revealed various efficacies against studied Candida species. The susceptibility to fluconazole and voriconazole were 100% for C. albicans, 50% and 90% for C. glabrata, and 0% and 100% for C. krusei isolates, respectively. The mean diameter of the inhibition zone was greater for thymol than carvacrol in C. albicans (19.89 ± 0.80 mm versus 17.05 ± 0.61 mm), C. glabrata (18.87 ± 0.71 mm versus 15.77 ± 0.57 mm), and C. krusei (15.11 ± 0.91 mm versus 13.91 ± 1.04 mm) isolates tested. Thymol showed more effective inhibition on adherence of all Candida species than other treatments. The mean relative adherence ratios for C. albicans, C. glabrata, and C. krusei were 0.50, 0.60, and 0.64, respectively. Conclusions: This study demonstrated significant inhibitory properties of thymol and carvacrol on the adherence and growth of azole susceptible- and -resistant Candida isolates. Also, thymol was more effective for preventing the adherence of yeast cells to polystyrene in comparison to carvacrol.
Martensite adaption through epitaxial nano transition layers in TiNiCu shape memory alloys

Titanium-rich TiNiCu shape memory thin films with ultralow fatigue have been analysed for their structural features by transmission electron microscopy. The stabilization of austenite (B2) and orthorhombic martensite (B19) variants epitaxially connected to Ti2Cu-type precipitates has been observed and found responsible for the supreme mechanical cycling capability of these compounds. Comprehensive ex situ and in situ cooling/heating experiments have demonstrated the presence of an austenitic nanoscale region in between B19 and Ti2Cu, in which the structure shows a gradual transition from B19 to B2 which is then coupled to the Ti2Cu precipitate. It is proposed that this residual and epitaxial austenite acts as a template for the temperature-induced B2↔B19 phase transition and is also responsible for the high repeatability of the stress-induced transformation. This scenario poses an antithesis to residual martensite found in common high-fatigue shape memory alloys.
Screening for Target Engagement using the Cellular Thermal Shift Assay - CETSA

The direct measurement of drug-protein interactions in living cells is a major challenge in drug discovery research. Using the cellular thermal shift assay or CETSA such measurements can be achieved, in principle, in any cell samples and in microtiter-plate format. This chapter starts with an overview of CETSA and then continues to provide thorough guidance in the development, optimization and application of a microplate-based protocol using AlphaScreen® as the detection format. Significant parts of the experimental descriptions are applicable also to other detection modalities. Each step in the assay development and validation process is exemplified by real case data from the development and validation of a fully screen-compatible live-cell assay for thymidylate synthase (TS; encoded by TYMS). When possible, the descriptions are kept general such that it allows for translation to other target proteins and efforts are made to point out crucial steps and considerations in the experimental design. At the end of the chapter there is a section devoted to insights from our screen adaptation experiences, troubleshooting and a discussion on tentative applications of microplate-based CETSA.
8-Hydroxydihydrosanguinarine (8-HDS), a pyridone containing analogue of sanguinarine, can be a potential inhibitor of S protein and M protease of SARS CoV2: Insights from computational studies

The unprecedented global pandemic of COVID-19 has created a daunting scenario urging an immediate generation of therapeutic strategy. Interventions to curb the spread of viral infection primarily include setting targets against the virus. Here in this study we target S protein to obstruct the viral attachment and entry and also the M pro to prevent the viral replication. For this purpose, the interaction of S protein and M pro with phytocompounds, sanguinarine and eugenol, and their derivatives were studied using computational tools. It is evident from the docking studies that 8-Hydroxydihydrosanguinarine, a derivative of sanguinarine, exhibits maximum binding affinity with both the targets. The binding energies of the ligand with S protein and M pro scored to be ΔGb-9.4 Kcal/mol and ΔGb-10.3 Kcal/mol respectively. MD simulation studies depict that the phytocompound could effectively cause structural perturbations in the targets which would affect their functions. 8-Hydroxydihydrosanguinarine distorts the α-helix in the secondary structure of M pro and RBD site of S protein. Protein-protein interaction study in presence of 8-hydroxydihydrosanguinarine (8-HDS) also corroborate the above findings which indicate that this polyphenol interfere in the coupling of S Protein and ACE2. The alterations in protonation of M pro suggest that the protein structure undergoes significant structural changes at neutral pH. ADME (Physicochemical, Lipophilicity, Water Solubility, Pharmacokinetics, Drug-likeness) property of 8- hydroxydihydrosanguinarine suggests that this could be a potential drug. This makes the phyto-alkaloid a possible therapeutic molecule for anti COVID-19 drug design.
