Operator Mixing and the AdS/CFT correspondence

We provide a direct prescription for computing the mixing among gauge invariant operators in N=4 SYM. Our approach is based on the action of the superalgebra on the states of the theory and thus it can be also applied to resolve the mixing in the dual string description. As an example, we focus on the supermultiplet containing the BMN operators with two impurities. On the field theory side, we derive the leading planar quantum corrections to the naive expression of the highest weight state. Then we use the same prescription in the BMN limit of the AdS5xS5 string theory and derive the form of the 2-impurity highest weight state. The string expression matches nicely the SYM result and provides a prediction for the mixing due to higher order quantum corrections in field theory.Comment: 21 pages, 3 figures. Typos correcte

Effectiveness of a healthy lifestyle promotion program as adjunctive teletherapy for treatment-resistant major depression during COVID 19 pandemic: A randomized clinical trial protocol

INTRODUCTION: Treatment-resistant depression (TRD) has a high prevalence and can be exacerbated by poor physical health and economic hardships, which have become common stressors during the current COVID-19 pandemic. The therapeutic approaches used to treat these patients are not always available, may be not be accepted by some patients, and often require face-to-face interactions. OBJECTIVE: The main aim of this study will be to evaluate the effectiveness of an Internet-based adjuvant lifestyle-based intervention for patients with TRD. METHODS: This will be a parallel, randomized, and controlled clinical trial. A total of 180 patients with TRD will be randomly allocated (1:1:1) to 1 of 3 groups: treatment prescribed by the mental health team and written suggestions for lifestyle changes (placebo control group); treatment prescribed by the mental health team, written suggestions for lifestyle changes, and an 8-week mindfulness-based cognitive therapy program (active control group); or treatment prescribed by the mental health team, written suggestions for lifestyle changes, and an 8-week lifestyle change promotion program (intervention group). We will perform this study during the COVID-19 pandemic, and will administer interventions by teletherapy, and contact participants by telephone calls, text messages, and/or teleconferences. We will collect patient data using questionnaires administered at baseline, immediately after the intervention, and after 6 and 12 months. The primary outcome will be score on the Beck Depression Inventory-II. The secondary outcomes will be score on the Clinical Global Impressions Scale (used to quantify and track patient progress and treatment response over time) and health-related quality of life measured using the European Quality of Life-5 Dimensions Questionnaire. DISCUSSION: Patients with TRD are especially vulnerable when face-to-face psychotherapy is unavailable. The main strength of the proposed study is the novelty of the intervention to be used as an adjuvant therapy. Our results may provide guidance for treatment of patients with TRD in future situations that require lockdown measures. CLINICALTRIALS REGISTRATION NUMBER: NCT04428099

A comparison of robust polynomial fitting, global geopotential model and spectral analysis for regional–residual gravity field separation in the Doñana National Park (Spain)

Doñana National Park is a protected area of approximately 500 km2 located on the SW coast of Spain with singular and interesting ecological and geological features. A gravimetric survey is presented where L&R gravity metres were used in the gravimetric observations with GPS and high-precision levelling positioning. Bouguer gravity anomalies were computed and least squares prediction was used for gross-error detection. Robust polynomial fitting, the recent EGM2008 global geopotential model (complete to degree and order 2159), and spectral analysis were tested for regional–residual gravity field separation. A detailed description of the gravimetric characteristics of the Doñana National Park is presented and the values of residual gravity anomalies were correlated with geological features, where the use of the EGM2008 global geopotential model has revealed an interesting tool for regional–residual gravity field separation. Finally, the interpretation of the results is justified by the well-known geological aspects of the park, but some modifications in the boundaries of the different geological features are needed in order to fit the modelled gravity with the residual gravity anomalies in the two cross-sections analysed.The studies presented here were part of CICYT (Spanish Research Directorate) research project nos.

Contribution to the study of mass movements : mudflow slides and block fall simulations

Several theoretical and practical developments in relation with mass movements (rock blocks, rockslides, mudflows) are presented as a contribution to the discussion. Some of them are field bases, and others are numerical simulations. First of all we present briefly some generalised Newtonian fluid models. Then the Arbitrary Lagrangian-Eulerian (ALE) formulation for viscous flows with free surface is described and an example of its applicability is discussed. A rock avalanche simulation using some simplifications within a F.E. or a Finite differences scheme is developed next. Then the mudflow balance of energy study technique is outlined. Finally, we explain our experiments in rock block simulations, and we present a tentative graph runout distance vs. volume of material. / Plusieurs développements théoriques et pratiques sur les mouvements en masse (chutes de blocs, écroulements rocheux, coulées de boues) sont présentés. Certains d'entre eux sont basés sur des observations de terrain, d'autres relèvent de la simulation numérique. Dans un premier temps, nous présentons brièvement quelques modèles de fluides de type Newtonien généralisé. Ensuite, une formulation Lagrangienne-Eulérienne pour les écoulements visqueux à surface libre est décrite et un exemple d'applicabilité est discuté. Une simulation d'avalanche rocheuse utilisant des simplifications au sein de schémas aux éléments finis ou aux différences finies est ensuite développée. Par la suite, la technique du bilan d'énergie pour une coulée de boue est détaillée. Enfin, nous expliquons nos expériences de simulations avec des blocs rocheux et nous proposons un graphe de la distance d'arrêt par rapport au volume de matériau

Evolution and diversity of the benthic fauna of the Southern Ocean continental shelf

The modern benthic fauna of the Antarctic continental shelf is characterized by the lack of active, skeleton-breaking (durophagous) predators such as crabs, lobsters and many fish, and the dominance in many areas of epifaunal suspension feeders. It has often been remarked that these ecological characteristics give the fauna a distinctly Palaeozoic feel, with the assumption that it may be an evolutionary relic. We now know that this is not so, and fossil evidence shows clearly that many of the taxa and life-styles that are absent now were previously present. The modern fauna has been shaped by a number of factors, important among which have been oceanographic changes and the onset of Cenozoic glaciation. Sea-water cooling, and periodic fragmentation of ranges and bathymetric shifts in distribution driven by variability in the size and extent of the continental ice cap on Milankovitch frequencies will all have caused both extinction and allopatric speciation. The modern glacial setting with relatively low terrestrial impact away from immediate coastal regions, and scouring by icebergs are the key factors influencing the ecology and population dynamics for the modern Antarctic benthos

Longitudinal association between self-injurious thoughts and behaviors and suicidal behavior in adolescents and young adults: A systematic review with meta-analysis

BACKGROUND: Adolescents with previous self-injurious thoughts and behaviors (SITB) have over 2-fold risk of dying by suicide, higher than older ages. This meta-analysis aims to disentangle the association of each SITB with subsequent suicidal behavior in adolescence/young adulthood, the contribution of each SITB, and the proportion of suicide deaths with no previous suicide attempt. METHODS: We searched 6 databases until June 2015. INCLUSION CRITERIA: 1. Assessment of any previous SITB [a) suicidal thoughts and behaviors (ideation; threat/gesture; plan; attempt); b) non-suicidal thoughts and behaviors (thoughts; threat/gesture; self-injury); c) self-harm] as a risk factor of suicide attempt or suicide death; 2. Case-control or cohort studies; 3. Subjects aged 12-26y. Random effect models, metaregression analyses including mental health and environmental variables, and population attributable risks (PAR)s were estimated. RESULTS: From 23,682 potentially eligible articles, 29 were included in the meta-analysis (1,122,054 individuals). While 68% of all youth suicide deaths had no previous suicide attempt, suicide death was very strongly associated with any previous SITB (OR=22.53, 95%CI: 18.40-27.58). Suicide attempts were also associated with a history of previous SITB (OR=3.48, 95%CI: 2.71-4.43). There were no moderating effects for mental health and environmental features. The PAR of previous SITB to suicide attempts is 26%. LIMITATIONS: There is considerable heterogeneity between the available studies. Due to limitations in the original studies, an over-estimation of the proportion dying at their first attempt cannot be ruled out, since they might have missed unrecognized previous suicide attempts. CONCLUSIONS: Although more than two thirds of suicide deaths in adolescence/young adulthood have occurred with no previous suicidal behavior, previous SITBs have a much higher risk of dying by suicide than previously reported in this age group
