Prediction of player position for talent identification in association netball: a regression-based approach

Among the challenges in industrial revolutions, 4.0 is managing organizations’ talents, especially to ensure the right person for the position can be selected. This study is set to introduce a predictive approach for talent identification in the sport of netball using individual player qualities in terms of physical fitness, mental capacity, and technical skills. A data mining approach is proposed using three data mining algorithms, which are Decision Tree (DT), Neural Network (NN), and Linear Regressions (LR). All the models are then compared based on the Relative Absolute Error (RAE), Mean Absolute Error (MAE), Relative Square Error (RSE), Root Mean Square Error (RMSE), Coefficient of Determination (R2), and Relative Square Error (RSE). The findings are presented and discussed in light of early talent spotting and selection. Generally, LR has the best performance in terms of MAE and RMSE as it has the lowest values among the three models.
Metallo-Drugs in Cancer Therapy: Past, Present and Future

Cancer treatments which include conventional chemotherapy have not proven very successful in curing human malignancies. The failures of these treatment modalities include inherent resistance, systemic toxicity and severe side effects. Out of 50% patients administrated to chemotherapy, only 5% survive. For these reasons, the identification of new drug designs and therapeutic strategies that could target cancer cells while leaving normal cells unaffected still continues to be a challenge. Despite advances that have led to the development of new therapies, treatment options are still limited for many types of cancers. This review provides an overview of platinum, copper and ruthenium metal based anticancer drugs in clinical trials and in vitro/in vivo studies. Presumably, copper and ruthenium complexes have greater potential than Pt(II) complexes, showing reduced toxicity, a new mechanism of action, a different spectrum of activity and the possibility of non-cross-resistance. We focus the discussion towards past, present and future aspects.
Spatiotemporal of the Coupling Relationship between Ecosystem Services and Human Well-Being in Guanzhong Plain Urban Agglomeration

Understanding the complex relationship between ecosystem services and human well-being during the rapid development of urban agglomerations can promote the sustainable development of urban agglomerations. In this paper, the InVEST model and ArcGIS10.2 were used to analyze the spatial and temporal evolution characteristics of ecosystem services and human well-being in the Guanzhong Plain urban agglomeration. On this basis, the coupling coordination index is used to reveal the spatiotemporal coupling relationship between them. (1) From 2010 to 2018, the water conservation services, soil conservation services, and carbon sequestration services of the Guanzhong Plain urban agglomeration showed a fluctuating downward trend. The spatial differences of ecosystem services were significant. (2) From 2010 to 2018, human well-being in the Guanzhong Plain urban agglomeration showed a fluctuating downward trend, with a decrease of 17%, and regional differences tended to narrow. (3) The coupling coordination degree between ecosystem services and human well-being has slightly decreased while maintaining the basic coordination state. The results show that there was a significant relationship between the decline of ecosystem services and the rapid development of the Guanzhong Plain urban agglomeration, and policies should be classified according to the coupling coordination types of human well-being and ecosystem services to promote the sustainable development of urban agglomerations.
A Resistorless Temperature-insensitive Electronically-adjustable Single VDGA-based Voltage-mode Instrumentation Amplifier

This article describes a novel voltage-mode instrumentation amplifier with fully electronic controllability and temperature insensitivity. Its circuit description is very simple comprising only single active building block namely voltage differencing gain amplifier (VDGA) without any passive elements to achieve high differential-mode gain and common-mode rejection ratio (CMRR). Its gain can be widely adjustable by electronic method via input bias currents, it then can be easily modified to automatic or microcontroller-based control systems. Several performances of workability of the proposed instrumentation amplifier are disclosed using PSpice simulation with the model parameter of 0. 25μm CMOS process. The output deviation due to temperature variation is about 0.00135%/°C. The total harmonic distortion (THD) of output voltage is 0.89%. Total power consumption of the proposed circuit is 0.18mW at ±1.2V power supply.
Investigation on Optimal Switching Oscillation Suppression for SiC MOSFET by Inductively Coupled Damping

SiC MOSFET has been revolutionizing power electronics but producing more severe switching oscillation due to its inherent faster switching speed and lower damping characteristics. The inductively coupled damping approach is promising since no additional circuit element is inserted into the power processing loop. Thus, reliability of this inductively coupled fashion is higher compared to other existing snubbers. However, prior-art analytical design techniques are mainly based on scrutinizing the peak impedance and only discussed under a certain specific coupling, which limited its suppression effect. In this article, by viewing from the terminals of both upper and lower SiC MOSFETs in a half-leg circuit, two-port networks are linearized from switching oscillation and developed to deduce the exact characteristic equations. Then, the optimal snubber configuration along with two key parameters, i.e., the inductance factor and the secondary resistance, are determined via the root locus method. It is revealed that the damping effect of RL in the strong coupling region is even better than that of the secondary RLC resonator. What is more, applying the coupled RL damping circuit could not only remarkably dampen the switching oscillations, but also greatly lower switching losses. Finally, discussion on selecting the optimal snubber parameters is illustrated in detail.
Efficient Single-Phase Grid Connected Transformer-less Inverter with Active and Reactive Power Control

High efficiency, Moderate cost, and less weight, transformer-less inverter for grid connected photovoltaic systems are gaining popularity. As a result, a number of transformer-free topologies have been developed and confirmed using only active power injection. Almost every worldwide legislation has recently required that grid-connected PV inverters handle a certain amount of imaginary power. Grid connected PV inverters within the rated power less than 3.5kVA should achieve a power factor of 0.95, from VDE-AR-N 4105 standard. For grid connected Photovoltaic system with reactive power regulation, a novel high efficiency transformerless architecture has been discussed in this research. The new topology structure is given, as well as the detailed operation concept with imaginary power flow. The suggested methodology high-frequency common-mode (CM) model and control are investigated. Using MOSFET switches to increase overall efficiency is possible thanks to the suggested scheme has an implicit circuit structure, which inhibits reverse recovery even when imaginary power is fed into the system. Less leakage current is achieved by keeping the common mode voltage constant at the midpoint of the input supply voltage. In conclusion to that, a one-kilowatt sample is created and examined to validate the proposed architecture. Experiments show that the suggested architecture may inculcate imaginary power into the utility grid without producing any additional leakage current. The proposed topology’s European and maximum efficiency are measured and determined to be 98.54 percent and 98.29 percent, respectively.
Hydrodynamical simulations for the common-envelope wind model for Type Ia supernovae

The single-degenerate (SD) model is one of the leading models for the progenitors of Type Ia supernovae (SNe Ia). Recently, a new version of the SD model, the common-envelope wind (CEW) model, has been proposed, which, in principle, has the potential to resolve most of the difficulties encountered by previous SD models. This model is still being developed and a number of open issues remain, such as the details of the mass-loss mechanism from the surface of the common envelope (CE), the main observational properties, and the spiral-in timescale of the binary inside the envelope. In this article, we aim to address these issues by considering hydrodynamical effects on the CE. Using the stellar evolution code MESA, we carried out a series of 1D hydrodynamical simulations of an asymptotic giant branch (AGB) star undergoing a common-envelope phase with different envelope masses (0.0007-0.06 solar mass). We found that the envelopes are always dynamically unstable, leading to regular mass ejection events if the envelope is more massive than the critical value of ~ 0.003 solar mass. The kappa mechanism can naturally explain this phenomenon. We also found that, due to the low mass of the CE, the estimated frictional luminosity caused by the spiral-in of the immersed binary is much less than the nuclear luminosity, and therefore will not affect the structure of the CE significantly. Our results imply that the CE in the CEW model cannot be very massive. We also present a rough estimate for the spiral-in timescale based on a simplified model. We found that, for reasonable assumptions, the timescale may be longer than a few 100,000 yr; therefore, the white dwarf may have enough time to increase its mass toward the Chandrasekhar mass, avoiding a merger with the companion.
Laser Ion Acceleration from Mass-Limited Targets with Preplasma

The interaction of high intensity laser radiation with mass-limited target exhibits significant enhancement of the ion acceleration when the target is surrounded by an underdense plasma corona, as seen in numerical simulations. The self-generated quasistatic magnetic field squeezes the corona causing the intensification of a subsequent Coulomb explosion of the target. The electric field intensification at the target edges and plasma resonance effects result in the generation of characteristic density holes and further contributes to the ion acceleration.The interaction of high intensity laser radiation with mass-limited target exhibits significant enhancement of the ion acceleration when the target is surrounded by an underdense plasma corona, as seen in numerical simulations.

Predict and Adjust with Logistic Regression

Within Stata there are two ways of getting average predicted values for different groups after an estimation command: adjust and predict. After OLS regression (regress), these two ways give the same answer. However, after logistic regression, the average predicted probabilities differ. This article discusses where that difference comes from and the consequent subtle difference in interpretation.
Gold Nanoparticles in Cancer Therapeutics and Diagnostics

Conventional treatment for cancer is done by chemotherapy, radiotherapy, and/or surgery, which work by inhibiting the growth of the rapidly dividing neoplastic cells and excision of the neoplastic tissue, respectively. These methods affect the healthy tissues along with the diseased ones, as chemotherapeutic agents often cause toxicity in the body and a variety of unfavorable side effects, which can highly impair bodily functions. Otherwise, while operating, there is the danger of some cancerous cells not being excised or unnecessary additional removal of healthy tissues, again causing the patient to lose some functionality of their body. The emerging field of nanotechnology helps to revolutionize imaging and therapeutic management in cancer. The use of metallic nanoparticles, especially those derived from an inert metal like gold, which has a great list of advantages such as high biocompatibility, non-toxicity, easy synthesis, and effective functionality, makes this innovative technology crucial for further propagation of this field. These nanoparticles have a dual function, i.e., helping in precise fluorescent bioimaging and drug delivery of potent medication to specific tissue sites without affecting the general area highly in a negative fashion. Thus, integrating these methods into current clinical practice would advance our methods for diagnostics as well as treatment while decreasing the stress on the patient, overall elevating medical practices.
Excitation of knotted vortex lines in matter waves

We study the creation of knotted ultracold matter waves in Bose–Einstein condensates via coherent two-photon Raman transitions with a Λ level configuration. The Raman transition allows an indirect transfer of atoms from the internal state ∣ a 〉 to the target state ∣ b 〉 via an excited state ∣ e 〉 , that would be otherwise dipole-forbidden. This setup enables us to imprint three-dimensional knotted vortex lines embedded in the probe field to the density in the target state. We elaborate on experimental feasibility as well as on subsequent dynamics of the matter wave.
Playing in ‘The Backyard’: Environmental Features and Conditions of a Natural Playspace Which Support Diverse Outdoor Play Activities among Younger Children

Outdoor play in nature-rich spaces has been associated with healthy development among young children. The diverse play opportunities afforded to children by natural playspaces can scaffold health benefits, appreciation of nature, and pro-environmental behaviors into adulthood. Environmental features and conditions of outdoor playspaces significantly influence the diversity and quality of play opportunities. Understanding how the physical environment can support high-quality play experiences can inform the design of stimulating, health-promoting playscapes for children. An observational behavior mapping framework was utilized to examine the environmental features of The Backyard, a large natural playscape, associated with play activities among young children. The Tool for Observing Play Outdoors was used to capture outdoor play types OPT), along with associated behavioral and environmental data, during seven days of field observation. While the playspace supported most OPTs, Physical and Exploratory play were most prevalent. Associations with activity intensity and risk play are also presented. Loose parts, particularly natural loose parts, were highly involved in most OPTs, but especially associated with Exploratory play. Ground topography showed some association with several OPTs and warrants further investigation. The environmental features of The Backyard supported an abundant and diverse range of outdoor play activities for young children and families.
PLA/PHB-Based Materials Fully Biodegradable under Both Industrial and Home-Composting Conditions

In order to make bioplastics accessible for a wider spectrum of applications, ready-to-use plastic material formulations should be available with tailored properties. Ideally, these kinds of materials should also be “home-compostable” to simplify their organic recycling. Therefore, materials based on PLA (polylactid acid) and PHB (polyhydroxybutyrate) blends are presented which contain suitable additives, and some of them contain also thermoplastic starch as a filler, which decreases the price of the final compound. They are intended for various applications, as documented by products made out of them. The produced materials are fully biodegradable under industrial composting conditions. Surprisingly, some of the materials, even those which contain more PLA than PHB, are also fully biodegradable under home-composting conditions within a period of about six months. Experiments made under laboratory conditions were supported with data obtained from a kitchen waste pilot composter and from municipal composting plant experiments. Material properties, environmental conditions, and microbiology data were recorded during some of these experiments to document the biodegradation process and changes on the surface and inside the materials on a molecular level.
Intradiscal Autologous Platelet-Rich Plasma Injection for Discogenic Low Back Pain: A Clinical Trial

Background Platelet-rich plasma (PRP) contains high concentrations of growth factors and cytokines and may promote healing and tissue formation and exert anti-inflammatory effects. PRP has been shown to improve intervertebral disc degeneration in vivo and in vitro. This study is aimed at evaluating the effectiveness of autologous PRP on discogenic low back pain (DLBP) at 48 weeks postinjection in patients who received a single intradiscal injection. Methods All patients received a single intradiscal injection of PRP in a prospective trial. The pain scores, lumbar function, and adverse events were assessed at 1 week, 4 weeks, 8 weeks, 12 weeks, 24 weeks, and 48 weeks postinjection and compared to the preinjection values (0 weeks). Results Data were analysed from 31 patients with a 94% follow-up rate. Compared to preinjection, pain and lumbar function were significantly improved, and there were significant differences (P < 0.05) over the 48-week follow-up. Twenty-two (71%) patients were classified as successes after the intradiscal injection of PRP. One patient received surgery at two weeks postinjection due to intervertebral discitis. Conclusions Intradiscal injection of PRP can significantly relieve pain sensation and improve lumbar function in patients with DLBP over a 48-week follow-up period. Further randomized controlled clinical trials are needed to assess the effects of this injection therapy.
Topology and Control Scheme of Machine Side Converter for Wind Power Conversion System

For wind power conversion system, electrical generator, machine side converter and grid side converter are the three integral parts. Among the electrical generator, permanent magnet synchronous generator is one of the preferred choice because of its different features. The synchronous generator converts the wind power to corresponding electrical power and machine as well as grid side converters are utilized to feed the electrical power to the utility grid. Analysis of different topology and control schemes of machine side converter are required to choose the suitable topology as well as the control scheme for the machine side converter. This paper provides a brief overview of different topologies and control scheme of machine side converter for wind power conversion system.
Immune cells‐derived exosomes: A promising strategy for COVID‐19 treatment

Coronavirus disease 2019 (COVID-19) has threatened the lives and health of billions of people since it swept across the world in December 2019.1 It causes pulmonary edema, dyspnea and lung failure in severe cases.2 The speedy infectivity of the virus limits the movement of people, causing economic stagnation, collapse of infrastructure and severe global shock.3 Frequent mutations of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) make the treatment and prevention of COVID-19 a genuine challenge.4 Fortunately, exosomes (Exos) derived from immune cells have the trend to expedite the exhaustion of immune cells, as well as regulate viral transmission, replication, and mutations (Figure 1). Thereby, the modulation of immune function by Exos is promising to the treatment of COVID-19. At present, there are a lot of researches and reviews on Exos and extracellular vesicles against COVID-19, while most of them focus on the role and possibility of treatment in specific sources,2,5–7 without the whole research
Holographic Space-time Models of Anti-deSitter Space-times

We study the constraints on HST models of AdS space-time. The causal diamonds of HST along time-like geodesics of AdS space-time, fit nicely into the FRW patch of AdS space. The coordinate singularity of the FRW patch is identified with the proper time at which the Hilbert space of the causal diamond becomes infinite dimensional. For diamonds much smaller than the AdS radius, RAdS, the time dependent Hamiltonians of HST are the same as those used to describe similar diamonds in Minkowski space. In particular, they are invariant under the fuzzy analog of volume preserving diffeomorphisms of the holographic screen, which leads to fast scrambling of perturbations on the horizon of a black hole of size smaller than RAdS. We argue that, in order to take a limit of this system which converges to a CFT, one must choose Hamiltonians, in a range of proper times of order RAdS, which break this invariance, and become local in a particular choice of basis for the variables. We show that, beginning with flat, sub-RAdS, patches of dimension D, the resulting CFT, constructed from the variables of HST, is inconsistent with the entropy of large black holes, unless one has at least two compact dimensions, whose size is of order RAdS. The argument is connected to a new observation about the scrambling rate of information localized on the compact dimensions. Our construction explains why large AdS black holes do not have the fast scrambling property. Our present approach cannot deal with models where string theory is weakly coupled and RAdS is of order the string scale, because the relationship between area and entropy is non-universal in such models. On spatial length scales longer than RAdS, our mapping of HST variables into CFT shares much with the Tensor Network Renormalization Group (TNRG)[1] and is a sort of evolving error correcting code[2].
Optimized planning target volume margin in helical tomotherapy for prostate cancer: Is there a preferred method?

We compare the dosimetrical differences between plans generated for helical tomotherapy by using the 2D or 3D the margining technique for the treatment of prostate cancer. Ten prostate cancer patients were included in this study. For 2D plans, the planning target volume (PTV) was created by adding 5 mm (lateral/anterior-posterior) to the clinical target volume (CTV). For 3D plans, a 5-mm margin was added not only lateral/anterior-posterior, but also superior-inferior, to the CTV. Various dosimetrical indices, including the prescription isodose to target volume (PITV) ratio, conformity index (CI), homogeneity index (HI), target coverage index (TCI), modified dose homogeneity index (MHI), conformation number (CN), critical organ scoring index (COSI), and quality factor (QF) were determined to compare the different treatment plans. Differences between the 2D and the 3D PTV indices were not significant except for the CI (p = 0.023). 3D margin plans (11195 MUs) resulted in higher (13.0%) monitor units than 2D margin plans (9728 MUs). There were no significant differences in any organs at risk (OARs) between the 2D and the 3D plans. Overall, the average dose for the 2D plan was slightly lower than that for the 3D plan dose. Compared to the 2D plan, the 3D plan increased the average treatment time by 1.5 minutes; however, this difference was not statistically significant (p = 0.082). We confirmed that the 2D and the 3D margin plans were not significantly different with regard to various dosimetric indices such as the PITV, CI, and HI for PTV and the OARs with tomotherapy.
