Tail risk adjusted clean energy portfolios in P2P transactive markets using Rachev ratio
Authors: M Jisma , Mohan Vivek , Thomas Mini Shaji , Thirumala Karthik 
Published: March 2023

AbstractRenewable energy sources (RES) and electric vehicles (EVs) pose ‘energy‐risk’ in peer energy commitments due to their temporal and spatial uncertainties. Thus, optimistic commitments in the peer‐to‐peer transactive energy market (P2P TEM) are improbable. This paper proposes a two‐stage master–slave portfolio optimization approach for combining energy‐risk of RES and EVs, and welfare‐risk of peers, in building clean energy portfolios. The master portfolio refers to the shares of renewable and EVs in P2P market settlement, whereas the slave portfolio gives the wind‐solar mix within renewables. Here, Rachev ratio, an index used in financial portfolio selection for tail‐risk management, is adapted and combined with Markowitz efficient frontier to find the optimal slave portfolio. Both the extreme tails are optimized, encouraging energy outputs far above forecast and discouraging those far below forecast. The master portfolio is obtained by maximizing the sum of the average welfare of the peers at the best (right) and worst (left) tails of the welfare distribution curve using stochastic weight trade‐off particle swarm optimization. The proposed portfolio selection approach is better in terms of increased expected energy output, improved utilization of RES and EVs, and better collective peer welfare.
Investigation of current balance methodologies for inductive power transfer coupler with multiple branches
Authors: Luo Mengna , Huang Zhicong 
Published: March 2023

AbstractIn the inductive power transfer (IPT) system, using multiple coil branches instead of a whole large coil can effectively solve the thickness problem and save space. In that case, there are small parameter differences in mutual inductance and self‐inductance between the coil branches in parallel. These differences are amplified in high‐frequency IPT systems, resulting in different currents flowing through the different coil branches. The current unbalance will create many hazards. Therefore, this paper analyzes the key factors that cause current to unbalance and studies the equivalent circuit model of an inductive power transfer system with secondary multiple parallel branches. Moreover, this paper designs the compensation circuit and studies two kinds of current balance methods. Furthermore, the parameter design criteria are detailed to obtain a nearly ideal current balance effect. The characteristic analysis, parameter design, and verification are described in detail.

SummaryErst wenn der Heilpraktiker auch psychische und emotionale Aspekte des Patienten betrachtet, wird ihm ein ganzheitlicher Zugang zum Patienten möglich. Für den Therapeuten gilt es, fixierte Haltungen des Patienten aufzuweichen und gleichzeitig Zuversicht auf den Behandlungs-erfolg zu vermitteln. Dabei wird der Heilpraktiker nicht selten mit eigenen Unzulänglichkeiten konfrontiert, die es zu meistern gilt. Von der menschlichen Begegnung mit all ihren Facetten profi-tieren am Ende sowohl der Patient als auch der Therapeut, indem sie sich gegenseitig in ihrer Entwicklung während des Behandlungsprozesses unterstützen und stärken.
Das Mittel als Bindeglied

These were evident from the time to time semen analysis reports of the patient and presence of a live foetus in his wife's diagnostic reports.
Evidence-Based Homoeopathy: A Case Report of Bilateral Chronic Venous Leg Ulcer Effectively Treated by Individualised Miasmatic Medicines
Authors: Ravin D. Sampaul 
Published: March 2023

AbstractVenous ulcers can occur when the veins in the legs do not push blood back to the heart. Blood backs up in the veins , building up pressure and accumulation of fluid prevents the nutrients and oxygen from getting to the tissues, resulting in cell death and formation of ulcer. Venous ulcer does interfere with quality of life and induces great deal of discomfort. Conventional medicine mentions chronic venous ulcer as surgical disease. In homoeopathy, this condition is treatable without surgery through individualised miasmatic approach. A successfully treated case of 57 years old male, suffering from bilateral chronic venous leg ulcer, complicated with two miasms is reported here.
Neuromuscular Complications of COVID-19: Evidence from the Third Year of the Global Pandemic
Authors: Suh Joome , Amato Anthony 
Published: March 2023

AbstractAccumulating evidence in the third year of the global pandemic suggests that coronavirus disease 2019 (COVID-19) can cause neuromuscular complications during or after the acute phase of infection. Direct viral infection and immune-mediated mechanisms have been hypothesized. Furthermore, in patients with underlying autoimmune neuromuscular diseases, COVID-19 infection may trigger a disease flare. COVID-19 vaccines appear to be safe and effective at preventing severe illness from COVID-19. Certain vaccines are associated with an increased risk of Guillain-Barré syndrome and possibly Bell's palsy, but the absolute incidence is low, and benefits likely outweigh the risks. Newer prophylactic therapies and treatments are also becoming available for patients who may not mount a sufficient response to vaccination or have contraindications. In this article, we discuss the current available evidence on neuromuscular complications of COVID-19 and clinical considerations regarding vaccination.

Abstract
In this work we demonstrate the magnetic shielding ability of a stack of YBa2Cu3O7 tape annuli. The annuli are cut from a 46 mm wide second generation coated conductor deposited on a Ni-5at.%W alloy ferromagnetic (FM) substrate. The inner bore of the stacked tapes is 26 mm and the outer diameter is 45 mm. Three samples with different height (24 mm, 14.9 mm, 9.9 mm) are studied. All the experiments are carried out at both room temperature and liquid nitrogen temperature (77 K). The shielding efficiency is investigated when the magnetic field is applied either parallel to the axis of the stack (axial shielding) or perpendicular to it (transverse shielding). Under an axial field, magnetic shielding is found to be effective (SF

) up to magnetic flux densities of 0.67 T. The presence of the FM substrates is found to have two important consequences. First, the stack of annuli is able to shield transverse flux densities in spite of its layered structure. Second, a finite magnetic shielding effectiveness is demonstrated at room temperature. In order to understand the contribution of the FM substrates to the shielding mechanism, we use the experimental field dependence of the magnetic permeability as determined independently from hysteresis loop measurements on the same substrates. A finite-element homogenized model solved with an H–φ formulation is shown to successfully reproduce the shielding factor of the stack at room temperature and 77 K, both under axial and transverse applied fields. These models are also used to assess the influence of the critical current density and the magnetic permeability on the shielding efficiency. Finally, the results are used to predict the magnetic shielding properties of higher stacks, demonstrating their significant potential to shield axial fields of

Twisted dust-acoustic waves in a self-gravitating dusty plasma with nonextensive q-distributed electrons and ions
Authors: Bukhari S , Irfan M , Ahmed Mubashar 
Published: March 2023

Abstract
We have investigated the twisted dust-acoustic waves (TDAWs) in an electrostatic self-gravitating dusty plasma whose electrons and ions are modelled by nonextensive q-distribution function while massive dust particles are Maxwellian distributed. A well-known kinetic theory is employed for this purpose where perturbed distribution function, electrostatic and gravitational potentials are expressed with Laguerre–Gauss functions. The governing equations of kinetic theory are solved together under paraxial approximations. The dispersion relations and instability growth rates are obtained for two situations; a) super-extensivity (q < 1) and b) sub-extensivity (q > 1). Significant modifications concerning the wave frequencies and growth rates are presented with respect to self-gravitation parameter, twist parameter, nonextensive parameter and streaming speed. It is observed that wave frequency and growth rate of TDAWs reduces in the presence of self-gravitating effects. Furthermore, the growth rates exhibit a significant enhancement in amplitude with the increase in twist parameter, q-parameter and streaming speed. Our present results may have applications in interstellar dust clouds and in the dusty plasma environments of Halley’s Comet.
Negative muons for the characterization of thin layers in Cultural Heritage artefacts

Published: March 2023

Abstract
Muonic atom X-ray Emission Spectroscopy (µ-XES) is a novel technique based on the detection of high-energy X-rays emitted after the interaction of a negative muon beam with matter. Thanks to the multi-elemental range, negligible self-absorption of the x-rays and the possibility of performing depth profile studies, the technique is a very powerful probe for the analysis of cultural heritage artefacts. By tuning the energy of the incident muon beam, indeed, it is possible to investigate the different layers that constitute a sample. In this work, we report preliminary results of the analysis on two fire-gilded surfaces, in which the data analysis is coupled with Monte Carlo-based simulation software. Here, to perform a depth profile characterization, the samples were analysed at different beam energies (or momentum). Each of the resulting x-ray spectra was then analysed and compared with the output of the simulations software and a remarkably good agreement was reached. The results of the work are promising and with this approach, it will be possible to enhance the capability offered by the technique, both in terms of data analysis and data interpretation.

Our final goal is to establish a platform for integrating arts and science, where historical heritage can be analyzed non-destructively by combining quantum beam techniques utilizing muons, neutrons, or photons. At the symposium, the status of the negative muon non-destructive analysis held at J-PARC MUSE on old Japanese coins (Koban, Cho-gin), bell-shaped bronze vessels of the Yayoi period, and old horse harnesses will be introduced.
Magnetic properties and muon localization in Cr2S3
Authors: Isah Muhammad Maikudi , Renzi Roberto De , Onuorah Ifeanyi John 
Published: March 2023

Abstract
We investigate the magnetic ground state of rhombohedral chromium sulphide Cr2S3 by density functional theory. We identify the muon implantation sites, their hyperfine couplings and the role of charge states in this compound. Our calculations show that we can obtain a compensated ferrimagnetic ground state. We find that strong electronic correlations are required to correctly obtain the semiconducting band behaviour of Cr2S3 in agreement with experiment. Relying on earlier µSR measurements, our calculations suggest that the two muon local fields in Cr2S3 are due to distinct charge states for two very close but distinct muon sites bonded between two sulphur atoms. Further analysis of the static field at the muon allows to determine by µSR the average Cr magnetic moment in good agreement with experiment.
Identifying muon sites “by eye” in KPF6 and KBF4

Published: March 2023

Abstract
Molecular magnets are one of the key research themes of µSR, but locating the muon stopping site in these compounds using density functional theory is often very challenging as their unit cells tend to contain a very large number of atoms. Nevertheless, many molecular magnets contain the [PF6]− and [BF4]− molecular ions, which, due to their fluorine nuclei, produce a distinctive µSR spectrum, which can give information about the muon stopping site. This paper details the calculation of the muon sites in the much simpler materials KPF6 and KBF4, providing insights which can be applied to situations where these molecular ions are found in complicated molecular magnets.

Published: March 2023

Abstract
This report is focused on the development and test of a TDC (time to digital converter) and amplifier circuit for a state-of-the-art positron detector with position sensitivity. A newly developed one chip amplifier-shaper-discriminator (ASD) circuit with 16 channels input and a high-resolution TDC with a timing resolution on the order of picoseconds were tested. Silicon photomultipliers (SiPMs) were employed to give electric pulses for the optical input coming from a pulsed laser. We have successfully controlled the threshold level of the ASD circuit and measured the time structure of the SiPMs, as well as their multiple photon response from the pulse height histogram and the time over the threshold (TOT) histogram measured by the sub-nano second TDC. This is a technical basis for the next generation detector system with the positron tracking capability.

Abstract
At J-PARC, the MuSEUM (Muonium Spectroscopy Experiment Using Microwave) collaboration aims to precisely measure the ground-state hyperfine splitting of muonium atoms arising from the muon and electron spins. The pulsed muon beam is stopped in a krypton gas cell to form muonium atoms. The transitions of spin states are induced with a microwave cavity, which are then measured by positron counters. After the previously performed successful measurements with a nearly-zero magnetic field, we are currently planning a measurement with the 2.9T magnetic field by measuring two Zeeman-split sub-levels, so that increased statistics will allow us to more precisely determine the transition frequency down to ∼1ppb. Moreover, a new microwave cavity with a unique geometry is being designed to perform the measurement at an even stronger field of 2.9T in the future.
Depth profiling of LE-µSR parameters with musrfit
Authors: Martins Maria Mendes , Suter Andreas , Salman Zaher , Prokscha Thomas 
Published: March 2023

Abstract
The study of thin-film and multi-layered structures with nanometer resolution is possible with low energy µSR (LE-µSR). Modeling of the measured µSR parameters such as diamagnetic asymmetry and relaxation rate as a function of sample depth can be obtained from a series of experimental implantation energy measurements and its correlation with the simulated stopping profiles. The fitting approach assumes a sharp transition between regions with distinct properties. The fitting method, previously developed in matlab, was implemented in musrfit, a free µSR data analysis framework written in C++. The main goal is to make this fitting method widely available for energy dependent measurements and to increase the modeling possibilities within musrfit.
Development of monitoring system for the muon rotating target at J-PARC using an infrared camera
Authors: Matoba S , Kawamura N , Makimura S 
Published: March 2023

Abstract
An infrared camera was installed in the proton beamline upstream of the muon-producing rotating target for real-time two-dimensional temperature imaging of the target. For the first time in a muon production facility, temperature profiles of the target during high-intensity proton beam irradiation were obtained. The observed temperatures were similar to the evaluated values. A moving image of the target was successfully taken during the rotation. Accumulation of moving image data is expected to provide information on the thermal conductivity change due to radiation damage, and is expected to make a significant contribution to the development of accelerators and nuclear materials.

The quantum critical point separates a superconducting phase coexisting with CDW from a pure superconducting phase, while in both phases superconductivity has a strong-coupling phonon-mediated BCS-like s-wave character.

Abstract
The design of hydrogels based on natural polymers that have modulation of antibacterial capacity, ideal performance in release capacity of encapsulated drugs, and desired bioactivity for applications in wound healing represents a modern trend in biomaterials. In this work, novel hydrogels of semi-interpenetrating polymeric networks based on collagen and xanthan gum (XG) were investigated. The linear chains of XG can semi-interpenetrate inside to matrix of crosslinked collagen with polyurethane under physiological conditions, generating amorphous surfaces with fibrillar-granular reliefs that have accelerated gelation time (about 15 min), super water absorption (up to 3100%) and high inhibition capacity of pathogenic bacteria such as Escherichia coli (up to 100% compared to amoxicillin at 20 ppm). The increment of XG in the hydrogel (up to 20 wt.%) allows for improvement in the storage module, resistance to thermal degradation, slow the rate of hydrolytic and proteolytic degradation, allowing to encapsulate and controlled release of molecules such as ketorolac and methylene blue; besides, it shows to keep the metabolic activity of fibroblasts and monocytes at 48 h of evaluation, without observing cytotoxic effects. The bioactivity of these hydrogels is improved since they have excellent hemocompatibility and enhanced cell proliferation. Specifically, the hydrogel with 20 wt.% of XG shows to decrease the production of tumor necrosis factor-α and CCL-2 cytokines, increasing the production of transforming growth factor-β in human monocytes, which could be used to modulate inflammation and regenerative capacity in wound healing strategies.
