Search for supersymmetry in proton-proton collisions at 13 TeV using identified top quarks

A search for supersymmetry is presented based on proton-proton collision events containing identified hadronically decaying top quarks, no leptons, and an imbalance p(T)(miss) in transverse momentum. The data were collected with the CMS detector at the CERN LHC at a center-of-mass energy of 13 TeV, and correspond to an integrated luminosity of 35.9 fb(-1). Search regions are defined in terms of the multiplicity of bottom quark jet and top quark candidates, the p(T)(miss) , the scalar sum of jet transverse momenta, and themT2 mass variable. No statistically significant excess of events is observed relative to the expectation from the standard model. Lower limits on the masses of supersymmetric particles are determined at 95% confidence level in the context of simplified models with top quark production. For a model with direct top squark pair production followed by the decay of each top squark to a top quark and a neutralino, top squark masses up to 1020 GeVand neutralino masses up to 430 GeVare excluded. For amodel with pair production of gluinos followed by the decay of each gluino to a top quark-antiquark pair and a neutralino, gluino masses up to 2040 GeVand neutralino masses up to 1150 GeVare excluded. These limits extend previous results.Peer reviewe

Pseudorapidity distributions of charged hadrons in proton-lead collisions at root s(NN)=5:02 and 8.16 TeV

The pseudorapidity distributions of charged hadrons in proton-lead collisions at nucleon-nucleon center-of-mass energies root s(NN) = 5.02 and 8.16 TeV are presented. The measurements are based on data samples collected by the CMS experiment at the LHC. The number of primary charged hadrons produced in non-single-diffractive proton-lead collisions is determined in the pseudorapidity range vertical bar eta(lab)vertical bar vertical bar(vertical bar eta cm vertical bar) <0.5 are 17.1 +/- 0.01 (stat) +/- 0.59 (syst) and 20.10 +/- 0.01 (stat) +/- 0.5(syst) at root s(NN) = 5.02 and 8.16 TeV, respectively. The particle densities per participant nucleon are compared to similar measurements in proton-proton, proton-nucleus, and nucleus-nucleus collisions.Peer reviewe

Ponderosa Pine Scenic Byway Interpretive Management Plan

The Ponderosa Pine Scenic (PPSB), which extends along Highway 21 from Boise, ID to Stanley, ID, provides wonderful opportunities to view unique wildlife and landscapes offered by the Boise and Sawtooth National Forests. This project updates the current interpretive signs on the PPSB to provide additional information regarding wildlife and ecosystems that will accompany the US Forest Service’s Wildlife Viewing Guide. To do this, we took a photographic inventory of the signs and determined the changes that are needed at each site. Based on our findings we created a detailed management plan which will serve as a guide for future implementation. A priority ranking system was used to determine which sites should first be improved. We also created a template for a wolf awareness sign to be used throughout the US Forest Service lands. Targeting pet owners, these signs will inform visitors of the wildlife in the area. We are providing the first steps towards bringing the Wildlife Viewing Guide to life along Highway 21

Motives underlying food consumption in the Western Balkans: consumers’ profiles and public health strategies

International audienceThis study aims to identify subgroups of consumers based on the health motives underlying their food choice in Western Balkan Countries.The survey (n = 2943) was based on the Food Choice Questionnaire (FCQ) and elicited information on socio-demographic characteristics, consumption frequency of healthy food products, nutrition knowledge and impulsiveness. Analysis of the FCQ data focused on items of "health and natural content" and "weight control" factors to identify clusters.The biggest group of the sample was weight control and health-concerned individuals (34 %), mainly urban women older than 50. The second group of respondents (31 %) was moderately motivated about health and weight. A third group was health concerned but paid less attention to weight control (21 %), mainly comprising men and people living with children. The last group consisted of unconcerned young men (14 %) eating less fruit and showing higher impulsiveness.Western Balkan consumers differ in the importance they attach to health and natural content and weight control. This insight is needed to target interventions

A cross-cultural segmentation of western Balkan consumers: focus on preferences toward traditional fresh cow cheese

BACKGROUND: Western Balkan countries (WBCs) have a long-standing culinary tradition. The promotion of traditional foods may be a tool for coping with modernisation trends in such transition economies. This paper explores consumer preferences toward food in this region, focusing on a traditional fresh cow cheese locally called ‘Mladi Sir’. This product was quoted in all the preliminary focus groups as a common traditional product present in the six WBCs studied: Bosnia–Herzegovina, Croatia, Macedonia, Montenegro, Serbia and Slovenia. RESULTS: After a literature review investigating the conceptof traditional foodinWBCsandthe implementation of focusgroups, asurveyincludingaconjointanalysisonpreferencesforfreshcowcheesewascarriedoutin2011tocollectdatafrom1200respondents. Four clusters of consumers were identified: one focused more on the local origin; one oriented more toward the scale of production(on-farmandsmall dairy); thethird favouringlowpricesandthefourth preferringhighpricesandindustrial products. CONCLUSION: Policy makers and the supply chain could take these differences in consumer preferences regarding traditional food products into account in order to develop specific strategies

Post-vaccination SARS-cov-2 infection in nursing home residents, Bordeaux, France

OBJECTIVE: To describe COVID-19 breakthrough infections in two nursing homes (NHs) sites of active COVID-19 clusters despite optimal vaccination coverage. METHODS: A cross-sectional study was conducted in two NHs of south-western France, following the investigation of COVID-19 clusters (February-March 2021). SARS-CoV-2-confirmed infection was defined by positive RT-PCR. Antibodies neutralization capacities were tested in a subgroup of fully-vaccinated and seropositive-residents. RESULTS: Of the 152 residents, 66% were female with median age 87 years (IQR: 80.0-90.2). Overall, 132 (87%) residents received 2 doses of vaccine, 14 (9%) one dose and 6 (4%) were unvaccinated. Forty-seven (31%) residents had confirmed infection (45 (98%) with variant 20I/501Y.V1). All 6 non-vaccinated residents, 4 /14 who had one dose and 37/132 that had two doses, were infected. Of the 39 residents reporting symptoms, 12 and 3 presented severe and critical disease, respectively. One resident with a confirmed infection died. Infected-residents had a median anti-S IgG titre of 19 116.0 (IQR: 3 028.0-39 681.8 AU/mL), 19 times higher than that of non-infected vaccinated persons (1,207.0; IQR: 494.0-2,782.0). In the subgroup of 19 residents tested for neutralizing antibodies, the neutralizing titre (50%) was strongly positively correlated with the anti-S IgG titre (correlation coefficient = 0.83), and 1.5 times higher for the infected than non-infected residents [5.9 (IQR: 5.3-6.9) vs. 3.6 (2.9-3.8)]. CONCLUSION: Institutionalized elderly persons who undergo breakthrough infection develop higher titres of anti-S IgGs, which are strongly correlated with the neutralizing capacity of the antibodies. These results advocate for additional vaccine doses in this population

Patient reported postoperative pain with a smartphone application: A proof of concept

Postoperative pain management and pain assessment are still lacking the perspective of the patient. We have developed and studied a prototype smartphone application for patients to self-record postoperative pain. The main objective was to collect patient and stakeholder critique of improvements on the usability in order to develop a definitive version. The secondary objective was to investigate if patient self-recording compared to nurse-led assessment is a suitable method for postoperative pain management. Fifty patients and a stakeholder group consisting of ten healthcare- and ICT professionals and two members of the patient council participated in this study. Main outcome Thirty patients (60%) found it satisfying or very satisfying to communicate their pain with the app. Pain experienced after surgery was scored by patients as ‘no’: 3 (6%), ‘little’: 5 (10%), ‘bearable’: 25 (50%), ‘considerable’: 13 (26%) and ‘severe’: 1 (2%). Forty-five patients (90%) were positive about the ease of recording. Forty-five patients (90%) could correctly record their pain with the app. Thirty-eight patients (76%) agreed that in-app notifications to record pain were useful. Two patients (4%) were too ill to use the application. Based on usability feedback, we will redesign the pain intensity wheel and the in-app pain chart to improve clarity for patients to understand the course of their pain. Secondary outcomes The median patient recorded pain app score 4.0 (range 0 to 10) and nurse recorded numerical rating scale (NRS) for pain NRS 4.0 (range 0 to 9) were not statistically different (p = 0.06). Forty-two percent from a total of 307 patient pain app scores were ≥ 5 (on a scale from 0 no pain at all to 10 worst imaginable pain). Of these, 83% were recorded as ‘bearable’ while only in 18% of the recordings patients asked for additional analgesia. The results suggest that self-recording the severity of postoperative pain by patients with a smartphone application could be useful for postoperative pain management. The application was perceived as user-friendly and had high satisfaction rates from both patients and stakeholders. Further research is needed to validate the 11-point numeric and faces pain scale with the current gold standards visual analogue scale (VAS) and NRS for pain
