SAMSLAM: Simulated Annealing Monocular SLAM
2013
This paper proposes a novel monocular SLAM approach. For a triplet of successive keyframes, the approach inteleaves the registration of the three 3D maps associated to each image pair in the triplet and the refinement of the corresponding poses, by progressively limiting the allowable reprojection error according to a simulated annealing scheme. This approach computes only local overlapping maps of almost constant size, thus avoiding problems of 3D map growth. It does not require global optimization, loop closure and back-correction of the poses.
From particular polynomials to rational solutions to the PII equation
2022
The Painlevé equations were derived by Painlevé and Gambier in the years 1895 − 1910. Given a rational function R in w, w ′ and analytic in z, they searched what were the second order ordinary differential equations of the form w ′′ = R(z, w, w ′) with the properties that the singularities other than poles of any solution or this equation depend on the equation only and not of the constants of integration. They proved that there are fifty equations of this type, and the Painlevé II is one of these. Here, we construct solutions to the Painlevé II equation (PII) from particular polynomials. We obtain rational solutions written as a derivative with respect to the variable x of a logarithm of a…
Pre-marital and pre-unional financial agreements and their circulation in the context of the new EU regulations 2016/1103 and 2016/1104
2021
Regulations (EU) 2016/1103 and 2016/1104 provide spouses and partners with the possibility to conclude agreements for the organization of their property regime but do not detail their content and structure. Moreover, while the possibility to conclude those agreements even prior to the marriage or the conclusion of a registered partnership is a valuable innovation in comparison with other European Regulations in family matters, some choices made by the European legislator on applicable law will likely be source of inconveniences. Furthermore, as for their recognition and enforcement in the participating Member States ? which will be based on the same rules enacted for decisions, authentic in…

Search for a Dark Leptophilic Scalar in e(+) e(-) Collisions
2020
Many scenarios of physics beyond the standard model predict the existence of new gauge singlets, which might be substantially lighter than the weak scale. The experimental constraints on additional scalars with masses in the MeV to GeV range could be significantly weakened if they interact predominantly with leptons rather than quarks. At an e+e- collider, such a leptophilic scalar (φL) would be produced predominantly through radiation from a τ lepton. We report herein a search for e+e-→τ+τ-φL, φL→ℓ+ℓ- (ℓ=e, μ) using data collected by the BABAR experiment at SLAC. No significant signal is observed, and we set limits on the φL coupling to leptons in the range 0.04<mφL<7.0 GeV. These bounds s…
Observation and Measurement of Forward Proton Scattering in Association with Lepton Pairs Produced via the Photon Fusion Mechanism at ATLAS
2020
The observation of forward proton scattering in association with lepton pairs (eþe− þ p or μþμ− þ p) produced via photon fusion is presented. The scattered proton is detected by the ATLAS Forward Proton spectrometer, while the leptons are reconstructed by the central ATLAS detector. Proton-proton collision data recorded in 2017 at a center-of-mass energy of ffiffiffi s p ¼ 13 TeV are analyzed, corresponding to an integrated luminosity of 14.6 fb−1. A total of 57 (123) candidates in the ee þ p (μμ þ p) final state are selected, allowing the background-only hypothesis to be rejected with a significance exceeding 5 standard deviations in each channel. Proton-tagging techniques are introduced f…
Search for a Stable Six-Quark State at BABAR
2019
Recent investigations have suggested that the six-quark combination uuddss could be a deeply bound state (S) that has eluded detection so far, and a potential dark matter candidate. We report the first search for a stable, doubly strange six-quark state in Upsilon -> S anti-Lambda anti-Lambda decays based on a sample of 90 million Upsilon(2S) and 110 million Upsilon(3S) decays collected by the BABAR experiment. No signal is observed, and 90% confidence level limits on the combined Upsilon(2S,3S) -> S anti-Lambda anti-Lambda branching fraction in the range (1.2-1.4)x10^-7 are derived for m_S < 2.05 GeV. These bounds set stringent limits on the existence of such exotic particles.

Clinical utility of HFABP in myocardial infarction
2018
Assessing chest pain patients presenting to the emergency area (EA) is still a clinical challenge, as acute myocardial infarction (AMI) diagnosis is not adjudicated in the majority of patients. New generation high sensitivity troponin assays (hs-cTn) still present some limitations, thus, novel biomarkers to early rule-in and rule- out myocardial infarction in chest pain patients presenting to the EA are sought after. Among all, heart- type fatty acid binding protein (h-FABP) has been largely investigated. Studies performed on HFABP in these patients present marked heterogeneity. However, it can be stated that HFABP is clearly not a reliable marker for AMI diagnosis, neither as a stand-alone…
Der gegenwärtige Stand der Blutfiltration - Grundlagen und klinische Bedeutung von Leukozytendepletions- und Mikroaggregatfiltern bei der Bluttransfu…
1993
In this review the role of the latest generation of leukodepletion blood filters and the adverse reaction of leukocytes i.e. alloimmunisation, immunosuppression, nonhaemolytic febrile transfusion reaction, platelet refractoriness, transmission of infectious agents are described and discussed. Leukocyte-poor blood component is indicated for patients with a history of nonhaemolytic febrile transfusion reaction, in avoiding alloimmunisation in patients waiting for transplantation or platelet refractoriness and in preventing CMV-infection. In the review the role of microaggregate filters in transfusion complications, namely, nonhaemolytic febrile transfusion reaction, thrombocytopenia, adult re…
