Comparing walking accessibility variations between groceries and other retail activities for seniors

This paper aims to compare walking accessibility levels between groceries and other types of retail for seniors, examining whether patterns are uniform (or not). The city of Granada, Spain served as case study. First, a questionnaire was administered with persons older than 55 years, assessing their willingness to reach different types of retail opportunities on foot. A total of 202 valid responses were obtained (171 face-to-face and 31 online): 56% women, average age 69 years old, 20% living alone, and average monthly family income between €1000-€2000. Second, the K-modes clustering algorithm was used to identify four seniors sub-groups: “non-motorized seniors between 65 and 75”, “motorized seniors between 65 and 75”, “non-motorized seniors older than 75”, and “motorized seniors younger than 65”. The variables used were: age, car availability, household income, and household composition. Third, by using the Kruskal-Wallis and Mann-Whitney tests (p-level <0.05), a comparison of time-willingness functions to walk to retail was made between seniors sub-groups. The results revealed that walking accessibility to groceries are not significantly different among those sub-groups, while the accessibility levels to weekly retail are significantly lower for the “motorized seniors younger than 65” for time-willingness slots of 20–30 min. R software was used for statistical analysis

Effect of chestnut flour and probiotic microorganism on the functionality of dry-cured meat sausages

The meat industry has made efforts to develop meat and meat products with functional ingredients to prevent the risk of disease and to promote health conditions. Therefore, the aim of the present work was to study the combined use of the probiotic strain, Lactobacillus plantarum, and potential prebiotic chestnut flour in Spanish dry-cured sausage (Longaniza de Pascua). Chestnut flour and the probiotic strain improved LAB counts on Longaniza de Pascua without modifying product flavour. Chestnut flour had a significant effect on pH decrease and residual nitrite values, but lipid oxidation values were increased. The symbiotic meat product could be considered a healthy matrix as a probiotic carrier.Fil: Sirini, Noelí Estefanía. Consejo Nacional de Investigaciones Científicas y Técnicas.

Correlating material-specific layers and magnetic distributions within onion-like Fe 3 O 4 /MnO/ γ- Mn2 O3 core/shell nanoparticles

This article may be downloaded for personal use only. Any other use requires prior permission of the author and the American Institute of Physics.The magnetic responses of two nanoparticle systems comprised of Fe3 O 4/γ−Mn2O3 (soft ferrimagnetic, FM/hard FM) and Fe3O4/MnO/γ−Mn2 O3 (soft FM / antiferromagnetic, AFM/hard FM) are compared, where the MnO serves to physically decouple the FM layers. Variation in the temperature and applied field allows for Small Angle Neutron Scattering (SANS) measurements of the magnetic moments both parallel and perpendicular to an applied field. Data for the bilayer particle indicate that the graded ferrimagnetic layers are coupled and respond to the field as a single unit. For the trilayer nanoparticles, magnetometry suggests a Curie temperature (TC)≈ 40 K for the outer γ−Mn2O3 component, yet SANS reveals an increase in the magnetization associated with outer layer that is perpendicular to the applied field above TC during magnetic reversal. This result suggests that the γ−Mn2O3 magnetically reorients relative to the applied field as the temperature is increased above 40 K

Performance of the missing transverse momentum triggers for the ATLAS detector during Run-2 data taking

Artículo escrito por un elevado número de autores, solo se referencian el que aparece en primer lugar, los autores pertenecientes a la UAM y el nombre del grupo de colaboración, si lo hubiereThe factor of four increase in the LHC luminosity, from 0.5 × 1034 cm−2s−1 to 2.0 × 1034cm−2s−1, and the corresponding increase in pile-up collisions during the 2015–2018 data-taking period, presented a challenge for the ATLAS trigger, particularly for those algorithms that select events with missing transverse momentum. The output data rate at fixed threshold typically increases exponentially with the number of pile-up collisions, so the legacy algorithms from previous LHC data-taking periods had to be tuned and new approaches developed to maintain the high trigger efficiency achieved in earlier operations. A study of the trigger performance and comparisons with simulations show that these changes resulted in event selection efficiencies of > 98% for this period, meeting and in some cases exceeding the performance of similar triggers in earlier run periods, while at the same time keeping the necessary bandwidth within acceptable limit

Magnetic detection of sentinel lymph node in papillary thyroid carcinoma: The MAGIC-PAT study results

Introduction: Despite the controversy concerning sentinel lymph node biopsy (SLNB) in papillary thyroid carcinoma (PTC), successful detection rates can be achieved by radioguidance and vital dyeing. However, the drawbacks in both techniques are notable. Magnetic-guided SLNB (mSLNB) using superparamagnetic iron oxide (SPIO) nanoparticles is appealing as an alternative procedure. Materials and Methods: mSLNB using the Sentimag-Sienna System ® , total thyroidectomy and central compartment dissection (CCD) were performed on all PTC patients. Lymph node involvement was assessed by postoperative pathological examination. Results: From 2014 to 2016, 33 consecutive patients with PTC were enrolled in the study. A total of 20 patients met the eligibility. mSLNB succeeded in 16 patients, with a detection rate of 80%. A median of two SLN per patient were detected. A median of 10.5 non-sentinel lymph nodes (NSLN) from CCD were examined. Among the patients, 56.25% (9/16) had no metastatic nodes, while 12.5% (2/16) had exclusively SLN involvement. No false negative cases were found. The agreement between SLN and NSLN status was 87.5%. The prediction of NSLN involvement by SLN status showed 100% sensitivity, 81.8% specificity, 71.4% PPV and 100% NPV. Subsequently, mSLNB and the final pathological analysis would discriminate 43.75% (7/16) of patients who would certainly benefit from CCD whilst 56.25% of the total would confirm an unnecessary lymphadenectomy and avoid morbidity. Conclusion: mSLNB showed satisfactory performance in PTC with clinical-negative nodes. We have shown mSLNB to be a good predictor of central compartment status that can improve the staging and management of PTC patients

Search for new phenomena in final states with large jet multiplicities and missing transverse momentum using √s = 13 TeV proton-proton collisions recorded by ATLAS in Run 2 of the LHC

Artículo escrito por un elevado número de autores, solo se referencian el que aparece en primer lugar, los autores pertenecientes a la UAM y el nombre del grupo de colaboración, si lo hubiereResults of a search for new particles decaying into eight or more jets and moderate missing transverse momentum are presented. The analysis uses 139 fb−1 of proton-proton collision data at s = 13 TeV collected by the ATLAS experiment at the Large Hadron Collider between 2015 and 2018. The selection rejects events containing isolated electrons or muons, and makes requirements according to the number of b-tagged jets and the scalar sum of masses of large-radius jets. The search extends previous analyses both in using a larger dataset and by employing improved jet and missing transverse momentum reconstruction methods which more cleanly separate signal from background processes. No evidence for physics beyond the Standard Model is found. The results are interpreted in the context of supersymmetry-inspired simplified models, significantly extending the limits on the gluino mass in those models. In particular, limits on the gluino mass are set at 2 TeV when the lightest neutralino is nearly massless in a model assuming a two-step cascade decay via the lightest chargino and second-lightest neutralin

Measurement of isolated-photon plus two-jet production in pp collisions at √s = 13 TeV with the ATLAS detector

Artículo escrito por un elevado número de autores, solo se referencian el que aparece en primer lugar, los autores pertenecientes a la UAM y el nombre del grupo de colaboración, si lo hubiereThe dynamics of isolated-photon plus two-jet production in pp collisions at a centre-of-mass energy of 13 TeV are studied with the ATLAS detector at the LHC using a dataset corresponding to an integrated luminosity of 36.1 fb−1. Cross sections are measured as functions of a variety of observables, including angular correlations and invariant masses of the objects in the final state, γ + jet + jet. Measurements are also performed in phase-space regions enriched in each of the two underlying physical mechanisms, namely direct and fragmentation processes. The measurements cover the range of photon (jet) transverse momenta from 150 GeV (100 GeV) to 2 TeV. The tree-level plus parton-shower predictions from Sherpa and Pythia as well as the next-to-leading-order QCD predictions from Sherpa are compared with the measurements. The next-to-leading-order QCD predictions describe the data adequately in shape and normalisation except for regions of phase space such as those with high values of the invariant mass or rapidity separation of the two jets, where the predictions overestimate the dat

Search for tt¯ resonances in fully hadronic final states in pp collisions at √s = 13 TeV with the ATLAS detector

Artículo escrito por un elevado número de autores, solo se referencian el que aparece en primer lugar, los autores pertenecientes a la UAM y el nombre del grupo de colaboración, si lo hubiereThis paper presents a search for new heavy particles decaying into a pair of top quarks using 139 fb−1 of proton-proton collision data recorded at a centre-of-mass energy of s = 13 TeV with the ATLAS detector at the Large Hadron Collider. The search is performed using events consistent with pair production of high-transverse-momentum top quarks and their subsequent decays into the fully hadronic final states. The analysis is optimized for resonances decaying into a tt¯ pair with mass above 1.4 TeV, exploiting a dedicated multivariate technique with jet substructure to identify hadronically decaying top quarks using large-radius jets and evaluating the background expectation from data. No significant deviation from the background prediction is observed. Limits are set on the production cross-section times branching fraction for the new Z′ boson in a topcolor-assisted-technicolor model. The Z′ boson masses below 3.9 and 4.7 TeV are excluded at 95% confidence level for the decay widths of 1% and 3%, respectivel
