The definition and performance of objects in events containing top quarks are presented. More specifically, the trigger, reconstruction and identification criteria for electrons, muons and taus are ...described. The selection and data calibration of jets and b-jets are also discussed. The effect of pile-up are described for each object.
International conventions are seldom reviewed in the literature devoted to environmental policy instruments. However, coordination is needed at a global level for global environmental problems ...characterised by scientific controversies, uncertainty, irreversibility, long-term impacts, economic and geopolitical dimensions. The Convention on Biological Diversity is a good illustration in this regard. The rules it promotes are clearly inspired by mainstream economics. It has therefore been celebrated as a textbook example of sound environmental policy. However, its success has been limited so far and its position within the international conservation regime is challenged. We argue that an alternative analytical approach to environmental global policies is needed and that the French theories of conventions and régulation open up promising prospects in this respect.

Various types of silicon material and silicon p
+n diodes have been treated to increase the concentration of the oxygen dimer (O
2i) defect. This was done by exposing the bulk material and the diodes ...to 6
MeV electrons at a temperature of about 350
°C. FTIR spectroscopy has been performed on the processed material confirming the formation of oxygen dimer defects in Czochralski silicon pieces. We also show results from TSC characterization on processed diodes. Finally, we investigated the influence of the dimer enrichment process on the depletion voltage of silicon diodes and performed 24
GeV/
c proton irradiations to study the evolution of the macroscopic diode characteristics as a function of fluence.
The COVID-19 pandemic has spurred a hasty transition to virtual care but also an abundance of new literature highlighting telehealth's capabilities and limitations for various healthcare ...applications. In this review, we aim to narrate the current state of the literature on telehealth applied to migraine care. First, telemedicine in the context of non-acute headache management has been shown to produce non-inferior patient outcomes when compared to traditional face-to-face appointments. The assignment of patients to telehealth appointments should be made after referring more urgent cases to dedicated in-person clinics. During the virtual appointment, physicians can ask their patients about the "3 F's" in order to perform a thorough assessment of their headaches: frequency of headache days, frequency of acute medication usage and functional impairment. Clinical assessment scores that have been studied and deemed feasible for telemedicine, safe and efficient include the HIT-6, VAS and MIDAS scores. Although MIDAS was found to be redundant and inadequate to use on a daily basis, we suggest that it can be useful in periodic remote follow-up appointments. Additionally, several mobile health apps have been studied including Migraine Buddy, Migraine Coach and Migraine Monitor. All of these are appropriate for use in telemedicine when combined with an adequate trial period with Migraine Buddy being rated the highest, as it captures the most detailed clinical picture. High satisfaction rates have been reported for virtual headache management which were shown to be equal to in-person consults. These are based on patients' perceived increase in convenience due to avoided travel time, less disruption of their daily routine and feeling more comfortable in the environment of their choice. Despite this, limitations such as technological knowledge, access to videoconferencing modalities and having a more impersonal consultation with the physician may hinder some patients from adopting this service.

The COVID-19 pandemic has accelerated the transition to virtual healthcare while also prompting an abundance of new literature highlighting telemedicine's capabilities and limitations for various ...medical applications, notably musculoskeletal examinations. Telemedicine provides an opportunity to deliver timely patient- and family-centred care while maintaining physical distancing and improving access to remote communities. This review aims to narrate the current state of the literature on telemedicine applied in the context of a musculoskeletal examination for children aged 3 to 18 years. The PubMed and ScienceDirect databases were searched for relevant articles from January 2015 to August 2021 using a combination of keywords and nested searches. The general examination components relevant to the back and lumbosacral spine, hip, knee, ankle/foot, and gait are described. These components include inspection, palpation, range of motion, motor, and sensory examination as well as special testing. There is general feasibility, validity, and substantial reliability in performing most examination components, and primary diagnoses established virtually were found to be either the same or similar in the vast majority of cases. Despite the current literature focusing mainly on adult populations, we describe how each aspect of the exam can be reliably incorporated into a virtual appointment specific to the pediatric population. Currently available smartphone-based applications that measure joint range of motion were generally found to have high reliability and validity. Caregivers are needed for most of the consultation, especially in younger children, but select physical exam maneuvers can be self-performed by older children and adolescents alone. By providing an overview of the available smartphone tools as well as the reliability and validity of remote assessments, this review not only establishes a foundation for a structured pediatric musculoskeletal examination, but also aims to increase providers' confidence in incorporating telemedicine into their practice.
With the COVID-19 pandemic hastening the adoption of telemedicine into clinical practice, it has also prompted an abundance of new literature highlighting its capabilities and limitations. The ...purpose of this review is to summarize the current state of the literature on telemedicine applied in the context of a musculoskeletal examination of the neck and upper limbs for children 3 to 18 years old. The PubMed and ScienceDirect databases were searched for relevant articles from January 2015 to August 2021 using a combination of keywords and nested searches. General examination components including inspection, guided self-palpation, range of motion, sensory and motor examination, as well as special testing are described. Although the literature is focused mainly on adult populations, we describe how each component of the exam can be reliably incorporated into a virtual appointment specific to pediatric patients. Caregivers are generally needed for most consultations, but certain maneuvers can be self-performed by older children and adolescents alone. There is general feasibility, validity, and substantial reliability in performing most examination components of the upper limbs remotely, except for the shoulder exam. Compared to those made in person, clinical diagnoses established virtually were found to be either the same or similar in most cases, and management decisions also had high agreement. Despite this, there is evidence that some pediatric providers may not be able to collect all the information needed from a telemedicine visit to make a complete clinical assessment. Lastly, currently available smartphone applications measuring joint range of motion were found to have high reliability and validity. This narrative review not only establishes a foundation for a structured pediatric musculoskeletal examination, but also aims to increase physicians' confidence in incorporating telemedicine into their standard of care.

The 5th International Workshop on Top Quark Physics (TOP 2012) took place in Winchester, UK, from the 16–21 September. It gathered students as well as people active in the top quark sector and ...provided a framework to highlight the newest results and matters related to top quark physics. Discovered in 1995, the top quark is the sixth and heaviest of all quarks, and it is the only one with a lifetime short enough to be observed 'naked'. This makes it an important testing ground in the search for new physics. In fact, the fact of its mass being so much larger than the other quarks, hints at its special role in the Higgs mechanism. For the same reason, in many models of New Physics, new heavy resonances are expected to couple mostly with top quarks. Even if no new particles are observed, the direct correlation between its angular momentum and that of its detectable decay products allows us to probe indirectly New Physics in action when top quarks are created. In this edition of the TOP conference series, for the first time, the agenda was equally balanced between 'traditional' measurements and the now vast number of searches for physics BSM in the top quark sector, thanks mostly to the amount of data collected at the LHC in its Run I. New results were presented by both the Tevatron and the LHC collaborations: improved ttbar and single top cross-section measurements, refined techniques to measure the top quark mass and a large number of results on properties such as spin correlation and W boson polarization in top quark decays were shown. More technical discussions on the experimental issues, both from the detector and the simulation side also took place, drawing together experimentalists and theorists. Reviews of the latest results on ttbar asymmetry both from CDF and D0 and from ATLAS and CMS were shown, and theorists active in the field made some interesting points on this hot topic. Additionally, results on the search for fourth generation fermions and new resonances in the boosted top regime were also provided. Finally, a set of dedicated talks on the interplay between the top sector and other hot subjects, like the Higgs and SUSY, were given both at the theory and experimental level. Furthermore, ad hoc student sessions were organized to allow younger colleagues to pose questions to the senior experts in the field and contribute with their more recent studies. The conference has been a definitive success, not just scientifically: about 130 participants from all over the world created a collegiate spirit which culminated in the social events at Winchester Hall below King Arthur's table; and in a cosy 16th century barn for the social dinner. The Local Organizing Committee would like to thank all participants, and in particular the speakers, for their high level contributions to TOP 2012 and for making this a very fruitful and pleasant time together. We conclude by wishing the Organizing Committee of TOP 2013 all the best for a successful conference. We look forward to seeing everyone in Germany in 2013.
