Kinematic Characteristics of National and College Level Weightlifters during the Snatch Technique Using Wearable Inertial Sensors

Weightlifting performance is strongly dependent on technique, explosive strength, and flexibility. There are two major lifts involved in competition: the snatch and the clean and jerk, and the snatch is the most technical component of the weightlifting competition. Most technical analyses have previously been performed using either video analysis or conventional optical camera systems. However, few studies have investigated the kinematic characteristics of the weightlifters using inertial measurement unit (IMU) sensors. In this study, we investigated the joint kinematics of the trunk, shoulder, elbow, hip, and knee as well as the main phases during the snatch technique for national and college level weightlifters using multiple IMU sensors. Seven female Mongolian weightlifters (three national level and four college level) participated. Each participant performed three snatch attempts at 70% of their one-repetition maximum. The joint angles were calculated using three-axis acceleration and three-axis gyroscope data from the IMU sensors. The six main phases of the snatch technique were defined based on knee flexion. All parameters were compared between the national and college level weightlifters. The national team showed a higher elbow range of motion and a greater extension of the hip and knee joints at the second pull compared with college-level athletes. In addition, the college team did not exhibit the transition phase, and the proportion of the turnover phase was larger. This study provides a kinematic difference between the two different level weightlifters, which may help coaches and athletes to improve their training strategy and weightlifting performance.
Youth as e-citizens: engaging the digital generation

The growth of the Internet has dramati- cally altered the ways in which individuals use the media, and youth are at the fore- front of these changes. iGeneration Y, the nearly 60 million individuals born after 1979, represents the largest generation of young people in the nationis history, and the first to grow up in a world saturated with networks of information, digital devices, and the promise of perpetual connectivity. Although teens overall spend less time online than do adults (for a variety of reasons, including busy school and after-school schedules and the need to share Internet access with others), they are much more involved in the interactive and communications aspects of the Internet.
Nullspace Conditions for Block-Sparse Semidefinite Systems

We consider the recovery of low-rank matrices via a convex nuclear-norm minimization problem and present two null space properties (NSP) which characterize the uniform recovery for the case of blockdiagonal matrices and block-diagonal positive semidefinite matrices. Moreover, we show that the NSP for block-diagonal positive semidefinite matrices is weaker than the NSP for block-diagonal matrices. As a special case, we obtain a similar NSP for block-sparse and nonnegative vectors, which is again weaker than the known NSP for block-sparse vectors.
PIPELINES OF PORK Japanese Politics and a Model of Local Opposition Party Failure

The Liberal Democratic Party (LDP) has dominated Japanese politics since 1955, and the party’s even greater dominance of subnational level elections is much of the reason why. This article seeks to explain local electoral outcomes in Japan by focusing on two key features of the Japanese political system: the heavy centralization of governmental finances and an emphasis on clientelistic exchange. Because Japan’s political system focuses so heavily on the clientelist distribution of goods, local politicians and voters casting ballots in local elections have an incentive to align with parties that have access to the state budget. Because Japan’s public funds are primarily controlled by the central government, parties that control the national budget will be the most likely to benefit. In short, Japan’s fiscally centralized and clientelist system helps generate for the LDP a near monopoly on local power across most of Japan.
A Study on the Process Design of Advanced Planning & Scheduling for Transformer Operation Improvement

As enterprises, based on the forecast of the customer`s demand and collaboration with the suppliers, establish the integrated system directing supply, production, and distribution for the increase of productivity, Thus, this study intends to find the most urgent and critical factors for the improvement of the information system by externalizing factors affecting the operation of information system, suggest the process to improve the relevant functions of information system, and design the process. As a result of the analysis of the previous studies on the improvement of the information system, many studies were conducted on the improvement of ERP and SCM, yet there was no study conducted targeting about APS (Advanced Planning & Scheduling). Thus, this study chose APS as the subject for the design of the process for the improvement for the information system.
Fast Double-coupled Nonnegative Tensor Decomposition

—Coupled tensor decomposition has become a popular technique for the simultaneous analysis of multiblock tensors in recent years. To achieve group analysis of multiblock tensors, we propose a fast double-coupled nonnegative Canonical Polyadic decomposition (FDC-NCPD) algorithm. It enables the simultaneous extraction of common components and individual components. In addition, its time-consumption is greatly reduced without compromising the decomposition quality when handling large-scale problems. Simulation results demonstrate the superior performance of the proposed algorithm.

Accurate Resilient Average Consensus via Detection and Compensation

We study the problem of resilient average consensus for multi-agent systems with misbehaving nodes. Different from the widely investigated Mean-Subsequence-Reduced-based and detection-isolation-based approaches which guarantee consensus, in this paper, we address this problem by detecting misbehaviors, mitigating corresponding impact and achieving accurate average consensus. General types of misbehaviors are considered, including deception attacks and accidental faults. We characterize the disturbances of misbehaving nodes in a distributed manner via two-hop communication information and develop a deterministic detection-compensation-based consensus (D-DCC) algorithm with a decaying fault-tolerant error bound. Considering scenarios where such information is intermittently available, a stochastic extension named S-DCC is proposed. We prove that D-DCC and S-DCC allow nodes to asymptotically achieve average consensus exactly and in expectation, respectively. Finally, extensive simulations verify the effectiveness of the proposed algorithms.
Multimodal Immersive Learning with Artificial Intelligence for Robot and Running application cases

In research different MMLA applications were presented that provide a solution for a particular psychomotor learning task, e.g. CPR or table tennis. A common limitation in all applications is that they are domain specific. In this sense, we present the MILKI-PSY project, whose main goal is to provide a one-for-all system across different domains. Inherently given that different psychomotor learning tasks across domains have certain aspects in common, it would make a one-for-all system possible. Additionally, we present ideas for the MMLA data collection through different sensors and its respective storage, annotation, preparation, and exploitation. The proposed ideas are with respect to two learning tasks: running in the field of sports and collaborative montage in the field of human-robot interaction. Further, we suggest that the system must give to the user the freedom to decide what sensor data to use, and which feedback to receive. Ultimately, we opt for a scalable solution that can be provided to a larger audience.
Crop coefficients of Bt. cotton under variable moisture regimes and mulching G. V. PRAJAPATI and R. SUBBAIAH

An experiment was undertaken for two years (2013-14 and 2014-15) on sandy loam soils of Junagadh (21°30’ N, 70°27’ E) to determine crop coefficients of Bt. cotton under three mulch treatments (M1silver black plastic mulch, M2biodegradable plastic mulch, M3wheat straw mulch and C control) with two irrigation regimes (I11.0 IW/ETc, I2-0.8 IW/ETc). Actual evapotranspiration was estimated using soil moisture sensors. Results revealed that adjusted FAO K c predicts higher value than sensor based Kc values at both irrigation regimes. Silver black plastic mulch recorded lower crop coefficient values at all growth stage of Bt. cotton compared to biodegradable plastic mulch, wheat straw mulch and contro l. Sensor based Kc ini and Kc-devvalues of silver black plastic mulch observed 72.2, 29.0 and 66.9 and 14.8 per cent lower than control at 1.0 IW /ETc and 0.8 IW/ETc respectively. Overestimated adjusted FAO Kc values caused a loss of 78.1mm and 66.5mm of precious water at 1.0 IW/ETc and 0.8 IW/ETc respectively. This study admonishes blind adoption of published FAO Kc curves for mulch conditions.
Modeling the Philippine Cities’ Competitiveness Toward a Sustained Development Amid COVID-19 Pandemic

Cities and urban centers are viewed as drivers of regional and national development. The COVID19 pandemic and the subsequent enhanced community quarantine (ECQ) implemented by the Philippine government and related public mobility restrictions imposed had resulted to closure of businesses – from the micro, small, and medium enterprises (MSMEs) sector to several major industries in regional and provincial centers across the country. In the current crisis, it is argued that urban centers play a crucial role in sustaining the country’s competitiveness. Thus, we should not limit our understanding of cities competitive on rankings alone. Assessing the vital signs of competitiveness in terms of the underlying fundamentals that ultimately drive these results and providing prescriptions to address the economic challenges we are facing in this time of pandemic are also necessary. It is then at this level that the interrelationships of the four pillars of competitiveness – economic dynamism, government efficiency, infrastructure, and resiliency, should be understood better. Applying the structural equation modeling (SEM) approach, this study analyzes the interrelationships of these four pillars of competitiveness using the Cities and Municipalities Competitiveness Index (CMCI) data from 2017-2019. Through model development and analysis, the findings in this study provide direction for Philippine cities in framing their development agenda and recommendations for local government officials and development planners on what to prioritize in attaining and sustaining local competitiveness particularly in this very challenging time.
A recipe for inexact certiﬁcates in (cid:96) 1 -analysis interpolation

—Inexact dual certiﬁcates have become a staple of exact recovery studies in compressed sensing, particularly when dealing with structured measurements. Nonetheless, each time a new pair of sparsifying transform and measurement matrix is considered, the characteristics for identifying approximate certiﬁcate are re-derived, considering the particulars of whether the measurements are isotropic or the analysis operator is invertible or injective. This paper aims at describing a general recipe for supplying dual certiﬁcates that generalizes the existing ones in the literature while keeping constraints on the relevant linear operators to a minimum.
Design, Set-Up, and First Ignition of the RF Helicon-based Plasma Thruster

To extend missions lifetime at very low orbits (VLO), an efficient propulsion system is required for drag compensation. Atmosphere-Breathing Electric Propulsion (ABEP) is a concept that collects atmospheric particles to be used as propellant for an electric thruster. The system could nullify the onboard propellant storage requirements. Moreover, it can be applied to any celestial body with atmosphere (Mars, Venus, Titan, etc.), enabling novel missions at VLO for long periods. Challenging is the operation with atmospheric propellant, especially atomic oxygen (AO), highly present in Earth orbit, that causes erosion of (not only) major propulsion system components. The RF helicon-based plasma thruster is designed, built, and set-into operation. It is contactless and features a novel antenna called the birdcage antenna, derived from heritage of magnetic resonance imaging (MRI) machines. A static magnetic field is applied as 1) required boundary condition for the helicon wave formation in the plasma, and 2) provides further electromagnetic acceleration of the plasma. The first tests on Ar, N2, and O2 show a low input power requirement Pf ∼ 60W, easy ignition, and minimized reflected power Pr. Finally, a B-dot magnetic inductive probe is designed and integrated to verify the presence of helicon waves in the plasma plume. 1 ATMOSPHERE-BREATHING ELECTRIC PROPULSION The RF Helicon-based Plasma Thruster is designed within the H2020 DISCOVERER project [1], that aims to redesign very low Earth orbit (VLEO < 450 km) platforms by researching low drag materials, aerodynamic attitude control, and Atmosphere-Breathing Electric Propulsion (ABEP), see Fig. 1. Orbiting in VLEO can open a variety of novel space missions [1], however, the aerodynamic drag limits the mission’s lifetime. If a propulsion system is required, the limit is then imposed by the amount of propellant that can be carried. An ABEP system, instead, collects the atmospheric particles in VLEO by an intake and feeds an electric thruster. This can counteract the drag and remove to requirement of carrying propellant on-board. Moreover, it can be applied to any planet with atmosphere. The contact-less nature of the RF helicon-based plasma thruster removes the erosion issues due to the use of AO as propellant (dominant alongside N2 in VLEO), and produces a quasi-neutral plasma plume, removing the requirement of a neutralizer working on atmospheric
Electromagnetic band gap-dipole sub-array antennas creating an enhanced tilted beams for future base station

A novel customised electromagnetic band gap (EBG)-dipole sub-array antenna with a tilted beam for future base-station applications is presented. An enhanced tilted beam for the base-station antenna is one of the safest methods to increase radio coverage area adhering to the strict power requirements. An array of four dipole-EBG elements is designed demonstrating the enhanced down-tilt beam. Each single element consists of dipole antenna mounted on a customised EBG ground plane created by connecting several unit cells of the EBG. The proposed array radiates a tilted beam in order to achieve a high directivity at fixed down-tilt angle. The array antennas are simulated, fabricated and measured. The directivity of 11 dB is measured at the angle of 28° at 3.5 GHz. This directivity is 1.9 dB higher than the reference case that uses the broadside single element. In addition, the EBG-dipole array that can be mechanically tilted is designed. The proposed array antenna exhibits acceptable impedance matching across the operational frequency band.
Untargeted Metabolomics on Skin Mucus Extract of Channa argus against Staphylococcus aureus: Antimicrobial Activity and Mechanism

Microbial contamination is one of the most common food safety issues that lead to food spoilage and foodborne illness, which readily affects the health of the masses as well as gives rise to huge economic losses. In this study, Channa argus was used as a source of antimicrobial agent that was then analyzed by untargeted metabolomics for its antibacterial mechanism against Staphylococcus aureus. The results indicated that the skin mucus extract of C. argus had great inhibitory action on the growth of S. aureus, and the morphology of S. aureus cells treated with the skin mucus extract exhibited severe morphological damage under scanning electron microscopy. In addition, metabolomics analysis revealed that skin mucus extract stress inhibited the primary metabolic pathways of S. aureus by inducing the tricarboxylic acid cycle and amino acid biosynthesis, which further affected the normal physiological functions of biofilms. In conclusion, the antimicrobial effect of the skin mucus extract is achieved by disrupting cell membrane functions to induce an intracellular metabolic imbalance. Hence, these results conduce to amass novel insights into the antimicrobial mechanism of the skin mucus extract of C. argus against S. aureus.
Turning Instrument Background Into Science Data for Structural Features of Radiation Belts

Approaches regarding how to turn the instrument background counts into scientifically valuable data are presented in this Technical Report on Methods. The background counts due to penetrating energetic particles of radiation belts detected on Cluster CIS HIA and CODIF instruments and the Double Star HIA instrument are used in these approaches. In HIA spectrograms, the background counts are seen simultaneously in all energy channels marking the entry and exit of the radiation belts by the spacecraft, therefore, the locations of the boundaries of the outer and inner belts can be determined. In the case when HIA measurements are not readily available, a new method is proposed in which supplementary data streams within the CODIF telemetry is exploited. It employs separate counts that register “start,” “stop,” and “non‐valid” signals increasing in the presence of penetrating particles even when no corresponding increase are shown in the energy‐time spectrograms. The locations of the radiation belt boundaries are defined by following the changes in counts gradients with time and visual inspection of all the available measurements. The July–August 2007 and September–October 2012 time periods are analyzed for method demonstration on a presence of a third radiation belt, or storage ring.
Wideband Modeling of Transformer Common-Mode Characteristics Using RLC Ladder Network

For isolated power converters, both conducted and radiated electromagnetic interference (EMI) are dependent on the common-mode (CM) performance of transformers. This paper proposes an RLC ladder network modeling and its parameter extraction technique to characterize the wideband CM properties of transformers at the circuit level. It is proved that the ladder network covers detailed electric and magnetic parameters, therefore, is more applicable for wideband than commonly used lumped models. The finite element method (FEM) is selected to extract parameters for accuracy. Influential factors on parameters, including geometries and material properties are also presented. With S21 parameter as the evaluation method of transformers’ CM performance, the proposed modeling technique is verified from 100 kHz to 200 MHz on a planar transformer through the comparison between measured and simulated S21 parameter.
TALEN-Mediated Gene Editing of slc24a5 (Solute Carrier Family 24, Member 5) in Kawakawa, Euthynnus affinis

Transcription activator-like effector (TALE) nucleases (TALENs) mediated gene editing methods are becoming popular and have revealed the staggering complexity of genome control during development. Here, we present a simple and efficient gene knockout using TALENs in kawakawa, Euthynnus affinis, using slc24a5. We examined slc24a5 gene expression and functional differences between two TALENs that hold the TALE scaffolds, +153/+47 and +136/+63 and target slc24a5. Developmental changes in slc24a5 transcripts were seen in early-stage embryos by real-time PCR; slc24a5 expression was first detected 48 h post fertilization (hpf), which increased dramatically at 72 hpf. Four TALENs, 47- and 63-type of two different target loci (A and B), respectively, were constructed using Platinum TALEN and evaluated in vitro by a single-strand annealing (SSA) assay. TALEN activities were further evaluated in vivo by injecting TALEN mRNAs in the two-cell stage of the zygote. Most of the TALEN-induced mutants showed mosaic patterns in the retinal pigment epithelium (RPE) and fewer melanin pigments on the body at 72 hpf and later when compared to the control, implying the gene’s association with melanin pigment formation. A heteroduplex mobility assay (HMA) and the genome sequence further confirmed the TALEN-induced mutations of substitution, insertion, and deletion at an endogenous locus.
A channel resistance derivative method for effective channel length extraction in LDD MOSFETs

A channel resistance derivative method for extracting the electrical effective channel length and series resistance is proposed, and demonstrated on an advanced 0.35 /spl mu/m LDD CMOS technology. A clear graphic image of the L/sub EFF/ and R/sub SD/ is obtained directly from the measured channel resistance and its derivative with respect to the gate bias. The method also provides guidelines for the proper gate bias range selection in traditional L/sub EFF/ extraction techniques.
The Effect of Compression Wear for the Sport Performance and Muscle Function

The effect of compression wear for sport performance and muscle function was investigated based on the physiological test and electromyograph(EMG). The EMG test was used to study muscle activity after fitting the compression wear during exercise. It showed slight difference between men and women testee groups in the results of anaerobic, aerobic, fatigue, and EMG test due to muscle content in the body. In addition, the exercise performance was increased to some extent even the muscle activity was decreased. It is estimated that the compression effect to muscle by the compression wear decreased the muscle vibration and improved blood circulation which helped the entire sport performance. However, it is necessary to study the effect of compression wear in long-term wearing in the future study.
Secrecy Analysis with MRC/SC-Based Eavesdropper over Heterogeneous Channels

ABSTRACT In the perspective of information-theoretical security, inspired by the heterogeneity between legal and illegal channels, we consider the physical layer secrecy performance of a novel system model with a single antenna employed for both the transmitter and legal receiver, in the presence of a multiple antennas passive eavesdropper over dissimilar fading channels, where the legal/illegal channels are subject to Rayleigh/Nakagami-m and Nakagami-m/Rayleigh fading, respectively. We assume that the eavesdropper employs either maximal-ratio combining or selection combining reception in order to benefit from space diversity. Specifically, the exact closed-form expressions of the probability of existence of secrecy capacity and the secrecy outage probability are derived by utilizing statistical characteristics of the signal-to-noise ratio. Moreover, the delightful results reveal that the secrecy performance achieves a greater level when the Nakagami-m fading is supposed on the main link due to the line of sight component. In final, the analytical results are verified by Monte-Carlo simulation.
