To ensure business continuity in the post-COVID-19 era, decision-makers should reconfigure their traditional supply chain (SC) networks, assisted by the development and implementation of cutting-edge ...technologies. Recently, Industry 5.0 (I5.0) has gained increasing attention as a paradigm offering salient features for the creation of resilient and inclusive operations by ensuring long-standing SC sustainability. However, there has been insufficient analysis of the challenges of implementing I5.0 in SCs. Therefore, this study aims to understand the challenges of implementing I5.0 when managing the impact of SC disruptions due to the COVID-19 pandemic in an emerging economy. Both qualitative and quantitative methods were used for this research. First, the challenges to I5.0 implementation were identified through a literature review and experts’ feedback. Those challenges were examined and prioritised using the Best-Worst Method (BWM). Second, the contextual relationships amongst these challenges were analysed using interpretive structural modelling (ISM) with cross-impact matrix multiplication applied to classification (MICMAC) analysis. Findings showed that to adopt I5.0 initiatives successfully in order to manage the post-COVID-19 impact on SC sustainability, the active involvement of senior managers is required in the execution process. Findings also showed that financial support and funding (e.g., tax reduction, short loans, etc.) from investors and the government play a pivotal role in enabling sustainability in SCs. Finally, the challenges were classified using MICMAC analysis to provide valuable insights for managing future disruptions. This study is expected to help managers and decision-makers successfully overcome the challenges of implementing I5.0 in SCs and thus improve SC sustainability.
Because of the massive globalization process, market volatility, and today's ever-changing business environment, managing grain supply chains (GSCs) is becoming increasingly challenging. In addition, ...the ongoing Russia–Ukraine conflict is causing significant disruptions in global supply chains, adding to the challenges imposed by the COVID-19 pandemic in the last couple of years. The ongoing socio-economic disruptions have created a ripple effect in the global supply chains worldwide, especially in emerging economies, which also happen to be the major global exporters of food grains. In this regard, the key enablers of the GSC must be identified to address the impact of the ripple effect and ensure sustainability and food security. This paper addresses these challenges and amalgamates the knowledge on ripple effects, sustainability, and food security. The study aims to identify, prioritize, and delineate the systemic interrelationships among enablers to address the ripple effect of GSC in emerging economies like Bangladesh. A multi-method approach integrating Pareto analysis, total interpretive structural modeling (TISM), and matrice d'impacts croisés multiplication appliquée à un classement (MICMAC) was employed for this purpose. The findings of this study indicate that geological sourcing diversification, governing cash flow to avoid the liquidity crisis, and supplier clustering according to disruptive risks are the most significant enablers. The insights from this study can potentially assist industry leaders and GSC practitioners in making strategic decisions to achieve sustainability in the grain management sector and thus improve future food security in emerging economies.

We present a new result based on an analysis of the data collected by the MEG detector at the Paul Scherrer Institut in 2009 and 2010, in search of the lepton-flavor-violating decay μ(+)e(+)γ. The ...likelihood analysis of the combined data sample, which corresponds to a total of 1.8×10(14) muon decays, gives a 90% C.L. upper limit of 2.4×10(-12) on the branching ratio of the μ(+)→e(+)γ decay, constituting the most stringent limit on the existence of this decay to date.
The FAMU experiment aims to measure for the first time the hyperfine splitting of the muonic hydrogen ground state. From this measurement the proton Zemach radius can be derived and this will shed ...light on the determination of the proton charge radius. In this paper, we describe the scientific goal, the method and the detailed preparatory work. This includes the outcome of preliminary measurements, subsequent refined simulations and the evaluation of the expected results. The experimental setup being built for the measurement of the hyperfine splitting to be performed at the RAL laboratory muon facility is also described.
Deep brain stimulation (DBS) is one of the most important clinical therapies for neurological disorders. DBS also has great potential to become a great tool for clinical neuroscience research. ...Recently, the National Engineering Laboratory for Neuromodulation at Tsinghua University held an international Deep Brain Stimulation Initiative workshop to discuss the cutting-edge technological achievements and clinical applications of DBS. We specifically addressed new clinical approaches and challenges in DBS for movement disorders (Parkinson's disease and dystonia), clinical application toward neurorehabilitation for stroke, and the progress and challenges toward DBS for neuropsychiatric disorders. This review highlighted key developments in (1) neuroimaging, with advancements in 3-Tesla magnetic resonance imaging DBS compatibility for exploration of brain network mechanisms; (2) novel DBS recording capabilities for uncovering disease pathophysiology; and (3) overcoming global healthcare burdens with online-based DBS programming technology for connecting patient communities. The successful event marks a milestone for global collaborative opportunities in clinical development of neuromodulation to treat major neurological disorders.
Abstract The MEG II experiment based at PSI (Zuerich, Switzerland) has been committed and is taking data since 2021 to improve sensitivity on the decay μ + → e + γ . The pixelated Timing Counter ...(pTC), consisting of two arrays of 512 5 mm thick scintillator pixel each, read out by 6 3×3 mm 2 , 50 μm cell, Silicon Photomultipliers (SiPMs) from AdvanSiD, for a total of 6144 SiPM, achieves an overall resolution in the positron impact time of ∼43 ps when exploiting multiple measurements. To additionally improve this resolution, 4×4 mm 2 , 40 μm cell SiPMs have been selected to substitute a fraction of the old ones (about 1000 of them overall). By means of an automated test system, a first group of them has been characterized (measuring their breakdown voltage and their I-V curves), to match as much as possible SiPMs with the same gains in each pixel, in order to maximize the pixel time resolution. Such automated test system will be presented, together with some preliminary results on single pixel time resolution and the expectations of the average time resolution of the pTC in the coming years.
The MEG experiment makes use of one of the world's most intense low energy muon beams, in order to search for the lepton flavour violating process Formula omitted. We determined the residual beam ...polarization at the thin stopping target, by measuring the asymmetry of the angular distribution of Michel decay positrons as a function of energy. The initial muon beam polarization at the production is predicted to be Formula omitted by the Standard Model (SM) with massless neutrinos. We estimated our residual muon polarization to be Formula omitted at the stopping target, which is consistent with the SM predictions when the depolarizing effects occurring during the muon production, propagation and moderation in the target are taken into account. The knowledge of beam polarization is of fundamental importance in order to model the background of our Formula omitted search induced by the muon radiative decay: Formula omitted.

Abstract
The FAMU experiment aims at an indirect measurement of the Zemach radius of the
proton. The measurement is carried out on muonic hydrogen atoms (μH) produced through the
low-momentum (50–60 ...MeV/c) muon beam a the RIKEN-RAL μ
-
facility. The particle flux plays
an important role in this measurement, as it is proportional to the number of μH atoms
produced, which is the target of the FAMU experimental method. The beam monitor calibration
technique and results, presented here, are meant to extract a reliable estimation of the muon flux
during the FAMU data taking. These measurements were carried out at the CNAO synchrotron in Pavia,
Italy, using proton beams and supported by Monte Carlo simulation of the detector in Geant4.
The high precision measurement of the hyperfine splitting of the muonic-hydrogen atom ground state with pulsed and intense muon beam requires careful technological choices both in the construction of ...a gas target and of the detectors. In June 2014, the pressurized gas target of the FAMU experiment was exposed to the low energy pulsed muon beam at the RIKEN RAL muon facility. The objectives of the test were the characterization of the target, the hodoscope and the X-ray detectors. The apparatus consisted of a beam hodoscope and X-rays detectors made with high purity Germanium and Lanthanum Bromide crystals. In this paper the experimental setup is described and the results of the detector characterization are presented.
