We have searched for proton decay via p → e+π0 and p → µ+π0 modes with the enlarged fiducial volume data of Super-Kamiokande from April 1996 to May 2018, which corresponds to 450 kton·years exposure. We have accumulated about 25% more livetime and enlarged the fiducial volume of the Super-Kamiokande detector from 22.5 kton to 27.2 kton for this analysis, so that 144 kton·years of data, including 78 kton·years of additional fiducial volume data, has been newly analyzed. No candidates have been found for p → e+π0 and one candidate remains for p → µ+π0 in the conventional 22.5 kton fiducial volume and it is consistent with the atmospheric neutrino background prediction. We set lower limits on the partial lifetime for each of these modes: τ/B(p → e+π0) > 2.4 × 1034 years and τ/B(p → µ+π0) > 1.6 × 1034 years at 90% confidence level. Copyright © 2020, The Authors.

Overfishing is a global environmental problem that risks fisheries since many of the fish stock of the fisheries have already reduced to below a tolerable level. One of solutions that often implemented in the fishery management is by calculating the value of Maximum Sustainable Yield (MSY) as the maximum tolerable harvest that can be taken out from the natural stock without harming the population over an indefinite period of time. A proper tool used for computing the MSY is needed to support the fishery manager in solving this decision making problem. In this paper we propose a software development of Decision Support System (DSS) to address such fishery industry problem. The DSS is developed to compute the MSY from the annual yield-effort data of the fishery. We use two sigmoid growth equations, Logistic and Gompertz equations, as the underlying population models, which then are approximated by their discrete forms for computing several growth parameters. Most known methods of growth parameter estimation use a Multiple Linear Regression with Ordinary Least Square method (MLR-OLS). Here we propose the application of Artificial Neural Network with Linear Perceptron method (ANN-LP). A case study in this paper shows that the effectiveness of the proposed ANN-LP is as good as the MLR-OLS in estimating both the growth parameters and the MSY of the fishery in the case study needed in the computation of its MSY by using Artificial Neural Network (ANN) Linear Perceptron.

Due to a very low production rate of electron anti-neutrinos (¯ νe) via nuclear fusion in the Sun, a flux of solar ν¯e is unexpected. An appearance of ν¯e in solar neutrino flux opens a new window for the new physics beyond the standard model. In particular, a spin-flavor precession process is expected to convert an electron neutrino into an electron antineutrino (νe → ν¯e) when neutrino has a finite magnetic moment. In this work, we have searched for solar ν¯e in the Super-Kamiokande experiment, using neutron tagging to identify their inverse beta decay signature. We identified 78 ν¯e candidates for neutrino energies of 9.3 to 17.3 MeV in 2970.1 live days with a fiducial volume of 22.5 kiloton water (183.0 kton·year exposure). The energy spectrum has been consistent with background predictions and we thus derived a 90% confidence level upper limit of 4.7 × 10−4 on the νe → ν¯e conversion probability in the Sun. We used this result to evaluate the sensitivity of future experiments, notably the Super-Kamiokande Gadolinium (SK-Gd) upgrade. © 2020, CC BY.

As a baryon number violating process with ∆B = 2, neutron-antineutron oscillation (n → n¯) provides a unique test of baryon number conservation. We have performed a search for n → n¯ oscillation with bound neutrons in Super-Kamiokande, with the full data set from its first four run periods, representing an exposure of 0.37 Mton-years. The search used a multivariate analysis trained on simulated n → n¯ events and atmospheric neutrino backgrounds and resulted in 11 candidate events with an expected background of 9.3 events. In the absence of statistically significant excess, we derived a lower limit on n¯ appearance lifetime in 16O nuclei of 3.6 × 1032 years and on the neutron-antineutron oscillation time of τn→n¯ > 4.7 × 108 s at 90% C.L..

Spindle motor (three-phase asynchronous AC motor) is an important part of Computer Numerical Control (CNC) Printed Circuit Board (PCB) milling machine, which plays role to engrave the copper layer based on the PCB pattern design. To perform the engraving processes, it is necessary to adjust the spindle motor speed in accordance with the PCB material used. This paper presents the results of implementing a three-phase spindle-motor speed controller based on Field programmable Gate Array (FPGA). The control method used is fixed Voltage/Frequency (V/F) with Sinusoidal Pulse Width Modulation (SPWM) technique, so that the maximum torque of the motor can be maintained and the harmonic signals can be minimized. This sub-module consists of two main components, namely FPGA and three-phase inverter, which consists of opto-isolation circuit, logic inverter, MOSFET driver, and three-phase full-bridge inverter circuit. The FPGA unit generates digital SPWM signal as input to the inverter to convert DC voltage into three-phase AC voltage according to the given input frequency. Results show that the sub-module can control the speed in the range of 14000-28000 RPM with the corresponding frequency range of 250-500 Hz. The Sub-module also has constant V/F and Speed/Frequency (ω/F) characteristics. In addition, a ramp speed profile used during acceleration and deceleration has also been successfully implemented to address the problem of low starting torque due to the increase of supply frequency.

This paper presents the design, implementation, and application of a vision-based automatic system that measures facial interaction based on human's cognitive feature. We investigated the feature of people's facial interaction under natural gaze-movement via an experiment, and created criteria of k-degree facial interaction and face-to-face interaction depending only on facial orientation. These criteria were used to develop the automatic system. The system is vision-based. It could be easily embedded into applications. We focused on an application to understand the behavior of children with autism spectrum disorders (ASD), and tested the use of the automatic system in a robot-assisted activity for those children. The results suggested that the system could help to improve the efficiency of behavior analysis during the children's activities with the robot. The facial interaction measured between the children and the robot can be used by therapists to comprehend the children's psychological aspects and state of health.

Exotic nuclei are characterized by a number of neutrons (or protons) in excess relative to stable nuclei. Their shell structure, which represents single-particle motion in a nucleus [1, 2], may vary due to nuclear force and excess neutrons [3–6], in a phenomenon called shell evolution [7]. This effect could be counterbalanced by collective modes causing deformations of the nuclear surface [8]. Here, we study the interplay between shell evolution and shape deformation by focusing on the magnetic moment of an isomeric state of the neutron-rich nucleus 75Cu. We measure the magnetic moment using highly spin-controlled rare-isotope beams and achieving large spin alignment via a two-step reaction scheme [9] that incorporates an angular-momentum-selecting nucleon removal. By combining our experiments with numerical simulations of many-fermion correlations, we find that the low-lying states in 75Cu are, to a large extent, of single-particle nature on top of a correlated 74Ni core. We elucidate the crucial role of shell evolution even in the presence of the collective mode, and within the same framework, we consider whether and how the double magicity of the 78Ni nucleus is restored, which is also of keen interest from the perspective of nucleosynthesis in explosive stellar processes.

Jet substructure quantities are measured using jets groomed with the soft-drop grooming procedure in dijet events from 32.9 fb−1 of pp collisions collected with the ATLAS detector at s=13 TeV. These observables are sensitive to a wide range of QCD phenomena. Some observables, such as the jet mass and opening angle between the two subjets which pass the soft-drop condition, can be described by a high-order (resummed) series in the strong coupling constant αS. Other observables, such as the momentum sharing between the two subjets, are nearly independent of αS. These observables can be constructed using all interacting particles or using only charged particles reconstructed in the inner tracking detectors. Track-based versions of these observables are not collinear safe, but are measured more precisely, and universal nonperturbative functions can absorb the collinear singularities. The unfolded data are directly compared with QCD calculations and hadron-level Monte Carlo simulations. The measurements are performed in different pseudorapidity regions, which are then used to extract quark and gluon jet shapes using the predicted quark and gluon fractions in each region. All of the parton shower and analytical calculations provide an excellent description of the data in most regions of phase space.
