Ideal convergence and divergence of nets in (ℓ)(\ell )-groups

summary:In this paper we introduce the ${\mathcal I}$- and ${\mathcal I}^*$-convergence and divergence of nets in $(\ell )$-groups. We prove some theorems relating different types of convergence/divergence for nets in $(\ell )$-group setting, in relation with ideals. We consider both order and $(D)$-convergence. By using basic properties of order sequences, some fundamental properties, Cauchy-type characterizations and comparison results are derived. We prove that ${\mathcal I}^*$-convergence/divergence implies ${\mathcal I}$-convergence/divergence for every ideal, admissible for the set of indexes with respect to which the net involved is directed, and we investigate a class of ideals for which the converse implication holds. Finally we pose some open problems

Double approach operation for large extracompartmental proximal thigh tumors

Resection of large femoral triangle tumors that invade the bone (or vice versa) still remains a challenge. A lateral-only approach would hinder dissection of the mass, away from the femoral vessels, while an iliofemoral-only type of approach would make bone resection and megaprosthetic reconstruction very arduous. The authors describe a two-stage, one-position operation via a double surgical approach: the first stage is comprised by an iliofemoral approach and dissection of the femoral vessels, followed by proximal femoral resection and reconstruction stage. One illustrative case is presented along with the authors overall experience. We believe that this operation facilitates wide tumor resection in a safe and step-wise manner, as not to add to the morbidity of the procedure. J. Surg. Oncol. 2013;107:673679.

Pest categorisation of non‐EU Tephritidae

The Panel on Plant Health performed a group pest categorisation of non-EU Tephritidae, a large insect family containing well-studied and economically important fruit fly species and little studied species with scarce information regarding their hosts and species that do not feed on plants. Information was saught on the distribution of each species and their hosts. Tephritidae occur in all biogeographic regions except in extreme desert and polar areas, where their hosts are scarce or absent. Non- European Tephritidae are listed in 2000/29 EC as Annex 1/A1 pests whose introduction into the EU is prohibited. Non-EU Tephritidae are regularly intercepted in the EU. Interceptions mainly occur on fruits although there is potential for entry on other plant parts. Beginning with over 5,000 recognised species, factors relevant for pest categorisation were sequentially used to narrow down the list of species to create a list of Tephritidae not known to be established in the EU yet which occur in countries with some EU climate types and which feed on plants that occur in the EU. Following the introduction of pest species, impacts on cultivated host plants could result in yield and quality losses; harmful impacts on wild hosts are uncertain. Phytosanitary measures are available to prevent the entry of non-EU Tephritidae. Results are presented in a series of appendices listing species screened during the process. Of 4,765 species regarded as non-EU Tephritidae, 257 species satisfy the criteria assessed by EFSA such that they can be considered as potential quarantine pests for the EU. Lack of information of the distribution of hosts and/or impact on wild hosts means 1,087 species of non-EU Tephritidae do not satisfy all criteria to be considered as potential quarantine pests for the EU. Non-EU Tephritidae do not meet the criteria assessed by EFSA for consideration as regulated non-quarantine pests, as members of the group are not present in the EU and plants for planting are not the main means of spread

Procedures performed during neurosurgery residency in Europe

International audienceAbstract Background In a previous article ( 10.1007/s00701-019-03888-3 ), preliminary results of a survey, aiming to shed light on the number of surgical procedures performed and assisted during neurosurgery residency in Europe were reported. We here present the final results and extend the analyses. Methods Board-certified neurosurgeons of European Association of Neurosurgical Societies (EANS) member countries were asked to review their residency case logs and participate in a 31-question electronic survey (SurveyMonkey Inc., San Mateo, CA). The responses received between April 25, 2018, and April 25, 2020, were considered. We excluded responses that were incomplete, from non-EANS member countries, or from respondents that have not yet completed their residency. Results Of 430 responses, 168 were considered for analysis after checking in- and exclusion criteria. Survey responders had a mean age of 42.7 ± 8.8 years, and 88.8% were male. Responses mainly came from surgeons employed at university/teaching hospitals (85.1%) in Germany (22.0%), France (12.5%), the United Kingdom (UK; 8.3%), Switzerland (7.7%), and Greece (7.1%). Most responders graduated in the years between 2011 and 2019 (57.7%). Thirty-eight responders (22.6%) graduated before and 130 responders (77.4%) after the European WTD 2003/88/EC came into effect. The mean number of surgical procedures performed independently, supervised or assisted throughout residency was 540 (95% CI 424–657), 482 (95% CI 398–568), and 579 (95% CI 441–717), respectively. Detailed numbers for cranial, spinal, adult, and pediatric subgroups are presented in the article. There was an annual decrease of about 33 cases in total caseload between 1976 and 2019 (coeff. − 33, 95% CI − 62 to − 4, p = 0.025). Variables associated with lesser total caseload during residency were training abroad (1210 vs. 1747, p = 0.083) and female sex by trend (947 vs. 1671, p = 0.111), whereas case numbers were comparable across the EANS countries ( p = 0.443). Conclusion The final results of this survey largely confirm the previously reported numbers. They provide an opportunity for current trainees to compare their own case logs with. Again, we confirm a significant decline in surgical exposure during training between 1976 and 2019. In addition, the current analysis reveals that female sex and training abroad may be variables associated with lesser case numbers during residency

Search for stealth supersymmetry in final states with two photons, jets, and low missing transverse momentum in proton-proton collisions at s\sqrt{s} = 13 TeV

International audienceThe results of a search for stealth supersymmetry in final states with two photons and jets, targeting a phase space region with low missing transverse momentum ($p_\text{T}^\text{miss}$), are reported. The study is based on a sample of proton-proton collisions at $\sqrt{s}$ =13 TeV collected by the CMS experiment, corresponding to an integrated luminosity of 138 fb$^{-1}$. As LHC results continue to constrain the parameter space of the minimal supersymmetric standard model, the low $p_\text{T}^\text{miss}$ regime is increasingly valuable to explore. To estimate the backgrounds due to standard model processes in such events, we apply corrections derived from simulation to an estimate based on a control selection in data. The results are interpreted in the context of simplified stealth supersymmetry models with gluino and squark pair production. The observed data are consistent with the standard model predictions, and gluino (squark) masses of up to 2150 (1850) GeV are excluded at the 95% confidence level

Search for narrow trijet resonances in proton-proton collisions at s\sqrt{s} = 13 TeV

International audienceThe first search for narrow resonances decaying to three well-separated hadronic jets is presented. The search uses proton-proton collision data corresponding to an integrated luminosity of 138 fb$^{-1}$ at $\sqrt{s}$ = 13 TeV, collected at the CERN LHC. No significant deviations from the background predictions are observed between 1.75-9.00 TeV. The results provide the first mass limits on a right-handed boson Z$_{\mathrm{R}}$ decaying to three gluons, an excited quark decaying via a vector boson to three quarks, as well as updated limits on a Kaluza-Klein gluon decaying via a radion to three gluons

Observation of WWγ\gamma production and search for Hγ\gamma production in proton-proton collisions at s\sqrt{s} = 13 TeV

International audienceThe observation of WW$\gamma$ production in proton-proton collisions at a center-of-mass energy of 13 TeV with an integrated luminosity of 138 fb$^{-1}$ is presented. The observed (expected) significance is 5.6 (4.7) standard deviations. Events are selected by requiring exactly two leptons (one electron and one muon) of opposite charge, moderate missing transverse momentum, and a photon. The measured fiducial cross section for WW$\gamma$ is 6.0 $\pm$ 0.8 (stat) $\pm$ 0.7 (syst) $\pm$ 0.6 (modeling) fb, in agreement with the next-to-leading order quantum chromodynamics prediction. The analysis is extended with a search for the associated production of the Higgs boson and a photon, which is generated by a coupling of the Higgs boson to light quarks. The result is used to constrain the Higgs boson couplings to light quarks
