description: We report neutron diffraction measurements of Ca$_{0.6}$Sr$_{0.4}$MnSb$_2$, a low-carrier-density Dirac semimetal in which the antiferromagnetic Mn layers are interleaved with Sb layers that host Dirac fermions. We have discovered that we can detect a good quality inelastic spin wave signal from a small (m ~ 0.28 g) single crystal sample by the diffraction method, without energy analysis, using a neutron diffractometer with a position-sensitive area detector; the spin-waves appear as diffuse scattering that is shaped by energy-momentum conservation. By fitting this characteristic magnetic scattering to a spin-wave model, we refine all parameters of the model spin Hamiltonian, including the inter-plane interaction, through use of a three-dimensional measurement in reciprocal space. We also measure the temperature dependence of the spin waves, including the softening of the spin gap on approaching the Neel temperature, $T_N$. Not only do our results provide important new insights into an interplay of magnetism and Dirac electrons, they also establish a new, high-throughput approach to characterizing magnetic excitations on a modern diffractometer without direct energy analysis. Our work opens exciting new opportunities for the follow-up parametric and compositional studies on small, ~0.1 g crystals.

Subjects: Minors ; Moroccan Juvenile Justice ; Moroccan Penal Code

description: This article discusses the trend of juvenile justice and provides an overview to the study of Juvenile Justice laws presented in the Moroccan Penal Code. With the help of literature derived from the philosophies, processes, and practices of Moroccan Juvenile Justice, this work highlights that Moroccan juvenile justice policy intertwines between rehabilitative and punitive approaches to managing young offenders. As noted, Juvenile Justice relates to a child below 18 years. The article also examines official responses to delinquency as well as the recent development of Juvenile Justice in Morocco. It argues that the current system of delinquency control and juvenile justice should gradually move toward the adoption of a just restorative approach. The article recommends the creation of separate institutions or courts for the trial and rehabilitation of juveniles.

description: Depuis le début des années 2000, les moyens de communication modernes ont évolué et se sont diversifiés d'une manière inédite, restructurant les relations sociales et la compréhension de l'information et de la communication. La téléphonie mobile, Internet et leurs composants définissent de nouveaux modes de communication et modifient le rapport au langage, tout en bouleversant les frontières entre le langage verbal et écrit, donnant naissance à un discours interactif et inventé qui véhicule plus d’économie et de rapidité dans la parole. Notre contribution interroge ces caractéristiques ainsi que les évolutions et les mutations possibles du statut de l'écriture, qui se limite souvent, dans le monde numérique, à la transcription hybride et / ou réduite par rapport à l'oralité. Nous nous intéresserons, particulièrement, aux changements linguistiques apportés au niveau de la parole; à sa nature dynamique en mettant en évidence toutes les modalités du processus étudié, en l'occurrence l'alternance codique, la traduction, l'emprunt, la néologie du sens et l’interférence. D'un point de vue théorique, nous intégrerons nos réflexions dans le contexte sociolinguistique, le changement étant un produit social assurant des échanges symboliques entre les acteurs d'une communauté. Ce choix met en évidence également le caractère dynamique et permanent de la langue et sa capacité à se diffuser auprès des membres d’un groupe social, notamment auprès des jeunes, à travers leur ouverture sur différents réseaux de communication.

description: BackgroundQatar was anticipating approximately 1.2 million visitors during the FIFA World Cup 2022TM, significantly increasing the population, road traffic1 , and the number of emergency calls received,2 which could potentially affect the response and transportation times of emergency ambulances. This study investigates how the FIFA World Cup Qatar 2022TM affected the response and transportation times of ground emergency ambulances around the country during November and December 2022 in comparison to previous years. This information could prove valuable to agencies responsible for planning and providing medical coverage for major tournaments worldwide. MethodsQatar’s Hamad Medical Corporation Ambulance Service (HMCAS) 999 data relating to response and transportation times for the months of November and December 2019 to 2022 was compared with respect to the population size. ResultsFindings are reported in Table 1. As expected, Qatar’s highest population during the periods analysed was during the World Cup. Response and transport times were shortest during that period despite an increase in the population size. Both times were higher that could be anticipated based on the previous year population size and call volume as shown in Figure 1.ConclusionLarge-scale events present challenges for emergency medical services. However, HMCAS managed to maintain high performance levels in response and patient transport times. Contrary to expectations, response and transport times were at their shortest during the tournament compared to prior years despite the increased population. This can probably be explained by the measures put in place by the Police Traffic Department to minimise the number of vehicles on the roads, promoting the use of public transport which was free to match ticket holders, closure of many roads around Doha and stadiums, and an increase of the size of the ambulance fleet and workforce enabling more ambulances to respond to emergency calls.
Mitigating array-induced bias in ambient noise beamforming

Year: 2022

description: We show that the geometry of a seismic array affects estimates of velocity and propagation direction of ambient seismic noise wavefields measured with beamforming techniques. We demonstrate how this results in apparent anisotropy estimates and present first approaches to mitigate the effect. Beamforming is an array technique originating from earthquake seismology that has become increasingly popular to analyse the ambient noise wavefield with the goal to characterise ambient noise sources (e.g., regions of origin of Love and Rayleigh waves) as well as subsurface structures (shear-velocity profiles, fracture orientation). Beamforming techniques estimate the dominant velocity, direction of propagation, and (in case of three-component data) the polarisation of a wavefield recorded within a limited time window at a seismic array. An important parameter in beamforming is the array response function, which shows the response of an array to a wave that is arriving directly from below. It can be thought of as the fingerprint of the array and depends on the array geometry, i.e., number of stations, station spacing, and orientation of station pairs. A biased array can lead to oversampling of certain directions and, thus, prioritising them in the beamform heatmap.The first attempt to mitigate the influence of the array focuses on analysing the orientation of station pairs in an array and applying a weighting matrix in order to enhance contributions from orientations that are underrepresented. This approach leads to a modified array response function, that looks more regular and has the fingerprint of the array partly removed. Using synthetic data and different array geometries we demonstrate the effect on the estimated anisotropy. The second approach is based on simulating synthetic, isotropic wavefield recordings at an array of choice and measuring their dominant velocities and propagation directions using beamforming. Comparing expected and observed values shows that the effect of the array can be significant, in particular when multiple sources act simultaneously (as is often the case for ambient noise): both measured velocities and propagation directions are affected by the design of the array, leading to erroneous anisotropy estimates. Once we have an estimate of array-induced anisotropy, however, we can subtract it from the anisotropy measured in real data and thereby reduce the effect. Examples for different array geometries are presented and compared.

description: BackgroundMega sporting events attract many international fans, which may significantly impact the population size. Ambulance Services have finite resources to meet daily performance targets. The inability to cope with increased call volumes can negatively impact service performance and patient care. This study investigates how the FIFA World Cup (WC) Qatar 2022TM affected regular emergency ambulance call volumes, by comparing the number of ambulance dispatches during the football with previous call volume data for the same period in the previous three years.MethodsQatar’s 999 call volume data for the months of November and December 2019 to 2022 was compared with respect to the population size. This excluded patient encounters that occurred at pre-hospital mobile clinics of FIFA World Cup venues and with paramedic foot patrols.ResultsThe combined 999 call volume for November and December of each of the years of interest are reported in Table 1 alongside the average population size over the 2 months. The most significant population growth occurred in November and December 2022, with +8.01% rise compared to 2021. Regarding 999 calls, the greatest number of calls were during the competition months, with 48,645 calls. It was similar to what was anticipated based on a logistics regression analysis using previous years’ population size and call volume (Figure 1).ConclusionHosting countries such events must be well-prepared with resources, trained medical staff, and improved healthcare coordination to ensure everyone’s safety. The WC in Qatar had a noticeable impact on the country's population but a less than expected impact on emergency ambulance call volumes. This can be explained by the accessibility of clinics and paramedic foot patrols at all FIFA related venues who could deal with many patient complaints, hence reducing the need for calling an ambulance and visiting hospital emergency departments.

description: Calcium modulation is an important signaling process and could even contribute to cell apoptosis through ionic-induced perturbations in trans-membrane potential at the mitochondria. In this research, the numerical study constitutes a first step in quantitatively probing the time- and spatially-dependent modulation of calcium dynamics through the application of external electrical fields. The research uses both widely accepted deterministic continuum and discrete stochastic intracellular calcium models coupling with external electric field, with a focus on high-intensity ultrashort pulse electrical field.

For deterministic continuum intracellular calcium models with electric field assisted, numerical simulations for electrically induced, intra-cellular calcium-release from the endoplasmic reticulum are reported. A two-step model is used for self­ consistency. Distributed electrical circuit representation coupled with the Smoluchowski equation yields the ER membrane nanoporation for calcium outflow based on a numerical simulation. This is combined with the continuum Li-Rinzel model and drift- diffusion for calcium dynamics. The results are shown to be in agreement with reported calcium release data. A modest increase (rough doubling) of the cellular calcium is predicted in the absence of extra-cellular calcium. In particular, the applied field of 15k V/cm with 60 ns pulse duration makes for a strong comparison. No oscillations are predicted and the net recovery period of about 5 minutes are both in agreement with published experimental results. A quantitative explanation for the lack of such oscillatory behavior, based on the density dependent calcium fluxes is also provided.

A discrete stochastic intracellular calcium model coupled with lower electric field (1kV/cm) is to be studied as a first step to providing a more descriptive intracellular calcium model in response to external electrical fields. While a deterministic continuum intracellular calcium model is implemented in 1-D, discrete stochastic model is a 2-D simulation. Thus, this model can be used as a valuable visualization tool for better understanding of interactions between intracellular calcium and an external electric field.

In the context of multiple high-intensity ultrashort electric field pulses, simplified version of intracellular calcium coupled with an external model provides a suitable curve fitting that will be utilized to better match the simulation results with experimental data and to extract practical parameters of interest. The intracellular pore's closing time is one such parameter.

description: BackgroundGlobal pandemics amplified the need for eHealth literacy as young adults increasingly sought online health information. A recent study showed that the infodemic surrounding COVID-19 highlighted the importance of e-health literacy in health-related decisions. Another study highlighted the vital role of modern technologies on patients care. E-health literacy is “the ability to seek, find, understand, and appraise health information from electronic sources and apply the knowledge gained to addressing or solving a health problem”. It has numerous determinants, like the presenting health problem, level of education, and the technologies used. In our study we aim to explore the level of e-health literacy among young population, and identify influencing factors in the local context.MethodsWe used validated English and Arabic online questionnaires for students attending Qatar University. The score ranged between 8 - 40. E-Health literacy scores of ≥26 is considered to be high, while eHealth literacy scores of <26 are considered to be low. To analyse the data we used descriptive statistics, bivariant analysis. Statistical significance was set at a level of p ≤0.05 (Two-tailed).ResultsData was collected from 89 students. The non-response rate was over 71%. The participants’ mean age was 25±7 years old. Almost 42% were Qatari and more than half of them (68.5%) were females. Students mostly had high levels of health literacy (63%) (Table 1). There was no significant association between individual characteristics and levels of ehealth literacy including; area of study, hours of daily use of internet, and medical history.ConclusionThe findings suggests that students hold high levels of e-Health literacy. During pandemics, improving e-Health literacy among young adults is a multidimensional challenge that involves collaboration among stakeholders. Lastly, this study was carried out during the COVID-19 pandemic, which may have led to significant impact on the response rate.

description: The transport of Bloch electrons under strong fields is traditionally understood through two mechanisms: intraband Bloch oscillations and interband Zener tunneling. Here, we propose an oscillation mechanism induced by the interband quantum metric, which would significantly affect the electron dynamics under strong fields. By considering the multiband dynamics to the second order of the density matrix, we reveal that quantum metric induced oscillations (QMOs) persist regardless of band dispersion, even in exactly dispersionless flat bands. The resultant drift current can reach a magnitude comparable to the Bloch oscillation induced drift current in systems where interband tunneling is negligible. Notably, the QMO induced drift current increases linearly with electric field strength under the constraints of time-reversal or spatial-inversion symmetry, emerging as the primary delocalized current. We further show that both one-dimensional and two-dimensional superlattices are potential platforms for investigating QMO.

description: BackgroundThe Internationale Federation of Football Association (FIFA) World Cup (WC) is a global sporting event attracting millions of international spectators. The successful management of pre-hospital medical emergencies during such tournament is important to ensure the safety and well-being of attendees.MethodsA comprehensive assessment of the preparedness of ambulance services in WC host countries is important. It should involve a combination of surveys, interviews, and analysis of existing emergency response protocols and resources. Key areas of focus included ambulance fleet capacity, medical equipment and supplies, staff training, coordination with other emergency services, crowd management strategies, and readiness to respond to mass casualty incidents.ResultsQatar’s national Ambulance Service has taken into consideration the hosting of the WC since it was announced in 2010 as it was accompanied by a gradual and significant population growth.Thanks to governmental financial support and a visionary leadership, it greatly expanded in size, scope of service, and adopted modern technology, equipment, and practices (See Table 1). This has been accompanied by the development of evidence-based clinical practice guidelines and relevant training programmes that contribute to developing ambulance personnel to effectively handle a wide range of medical emergencies. Additionally, there has been increased collaboration between all emergency services to ensure a seamless response during the WC. Crowd management strategies were tested through exercises and implemented to reduce medical incidents in crowded areas around stadiums and fan zones.ConclusionThe critical role played by an ambulance service in responding to and managing emergencies at a mass gathering sporting event requires significant preparation and investments that can result in substantial improvements in the host countries’ prehospital care system. Many of the developments proved useful in managing the COVID-19 pandemic. Hosting the 2022 WC has resulted in long term benefits for the pre-hospital emergency medical services in Qatar.

description: Atom manipulation by scanning tunneling microscopy was used to construct quantum dots on the InAs(111)A surface. Each dot comprised six ionized indium adatoms. The positively charged adatoms create a confining potential acting on surface-state electrons, leading to the emergence of a bound state associated with the dot. By lining up the dots into N-dot chains with alternating tunnel coupling between them, quantum-dot molecules were constructed that revealed electronic boundary states as predicted by the Su-Schrieffer-Heeger (SSH) model of one-dimensional topological phases. Dot chains with odd N were constructed such that they host a single end or domain-wall state, allowing one to probe the localization of the boundary state on a given sublattice by scanning tunneling spectroscopy. We found probability density also on the forbidden sublattice together with an asymmetric energy spectrum of the chain-confined states. This deviation from the SSH model arises because the dots are charged and create a variation in onsite potential along the chain - which does not remove the boundary states but shifts their energy away from the midgap position. Our results demonstrate that topological boundary states can be created in quantum-dot arrays engineered with atomic-scale precision.

description: We study how to optimally segment monopolistic markets with a redistributive objective. We characterize optimal redistributive segmentations and show that they (i) induce the seller to price progressively, i.e., richer consumers pay higher prices than poorer ones, and (ii) may not maximize consumer surplus, instead granting extra profits to the monopolist. We further show that optimal redistributive segmentations are implementable via price-based regulation.

description: We use an information-theoretic argument due to O'Connell (2000) to prove that every sufficiently symmetric event concerning a countably infinite family of independent and identically distributed random variables is deterministic (i.e., has a probability of either 0 or 1). The i.i.d. condition can be relaxed. This result encompasses the Hewitt-Savage zero-one law and the ergodicity of the Bernoulli process, but also applies to other scenarios such as infinite random graphs and simple renormalization processes.

description: This article focuses on the impact of climate change on millet production in the Madaoua department, Niger. Niger is a country vulnerable to the effects of climate change due to its high climatic variability and its dependence on rain-fed agriculture. Millet is a crucial cereal grown in the region, accounting for a significant share of the country's cultivated area and cereal production. The objective of this study is to assess the impact of climatic parameters, such as temperature and rainfall, on millet yield. Production data and meteorological data were used to analyze rainfall trends and anomalies, as well as the variation in maximum temperature over a 30-year period (1992-2022). The results show a slight upward trend in mean annual rainfall, although year-to-year variability is high. Dry and wet years do not necessarily follow a linear trend. Dry years are associated with below-average precipitation, while wet years have above-average precipitation. The maximum temperature showed a steady increase over the years, with some fluctuations. In 2021, the average maximum temperature was 36.5°C. This increase in temperature may have a negative impact on millet production and food security in the region. The study also uses regression analysis to examine the relationship between millet yield and climatic parameters. The results of this analysis can help to better understand the effects of climate change on agriculture and to formulate recommendations for effective adaptation in order to maintain agricultural productivity and sustainability in the department of Madaoua.

description: BackgroundCefdinir, a third-generation oral cephalosporin, is prescribed by many pediatricians for otitis media. Red-colored, non-bloody stools represent a harmless yet alarming side effect of Cefdinir when co-administered with iron-fortified formulas or iron supplements. As it is under-reported in the literature, physicians’ familiarity with it is still limited. Case presentationA previously healthy 8-month-old girl presented to the Emergency Department with a 5-day history of normal-consistency ‘bloody’ stools with no abdominal pain, vomiting, or fever. Examination, coagulation studies, haemoglobin and platelet levels were normal. Stools were guaiac negative (Figure 1). Intussusception was ruled out by an abdominal ultrasound. Patient was discharged on esomeprazole and instructions to come back after 24 hours for review. In her second visit, history taking revealed that she was on iron-fortified formula and was started on Cefdinir for otitis media on the same day her symptoms started. Her mother was reassured when explained that this stool discoloration was a benign side effect of Cefdinir when taken with iron-fortified formula and is reversible after cessation of the antibiotic.RecommendationsCefdinir or its metabolites bind with iron in the gastrointestinal tract and impart a non-absorbable complex responsible for these reddish stools.2,3 Incidence of this side effect is still unknown. The earliest case documented was in 2008 and it is still underreported (Fewer than 15 cases in the literature).1 It does not indicate discontinuation of the antibiotic as it resolves when the course is complete.1 Workup should include at most a stool guaiac test. Careful nutritional and medication history should be obtained before prescribing Cefdinir. Caregiver education about this possible side effect occurrence and its benign nature is crucial. ConclusionAlthough it is probably a relatively rare occurrence, the Cefdinir drug label should include this side effect to avoid unnecessary emergency visits and investigations.
