To use Augmented Reality in an automotive vehicle for testing Advanced Driver Assistance Systems a new development approach with high computing power is needed. Reasons for this are a high vehicle speed as well as fewer possible orientation points on an urban test track compared to using AR applications inside a building. With the help of Image Segmentation, Artificial Intelligence for Object Detection, and Visual Simultaneous Localization and Mapping a 3-Dimensional Model with precise information of the urban test site is to be generated. Through the use of AI and Image Segmentation, it is expected to significantly improve performance like computing speed and accuracy for AR applications in automotive vehicles.

Great advances in automated identification systems, or ‘smart traps’, that differentiate insect species have been made in recent years, yet demonstrations of field-ready devices under free-flight conditions remain rare. Here, we describe the results of mixed-species identification of female mosquitoes using an advanced optoacoustic smart trap design under free-flying conditions. Point-of-capture classification was assessed using mixed populations of congeneric (Aedes albopictus and Aedes aegypti) and non-congeneric (Ae. aegypti and Anopheles stephensi) container-inhabiting species of medical importance. Culex quinquefasciatus, also common in container habitats, was included as a third species in all assessments. At the aggregate level, mixed collections of non-congeneric species (Ae. aegypti, Cx. quinquefasciatus, and An. stephensi) could be classified at accuracies exceeding 90% (% error = 3.7–7.1 …

Background Frailty is increasingly recognized for an association with adverse events, mortality, and hospital discharge disposition among surgical patients. The purpose of this study was to describe how spinal surgeons conceptualize, define, and assess frailty in the context of spinal metastatic disease (SMD). Methods We conducted an international, cross-sectional, 33-question survey of the AO Spine community. The survey was developed using a modified Delphi technique and was designed to elucidate preoperative surrogate markers of frailty in the context of SMD. Responses were ranked using weighted averages. Consensus was defined as ≥ 70% agreement among respondents. Results Results were analyzed for 312 respondents (86% completion rate). Study participants represented 71 countries. Most respondents informally assess frailty in patients with SMD by forming a general perception based on …

Instantons, which are nonperturbative solutions to Yang-Mills equations, provide a signal for the occurrence of quantum tunneling between distinct classes of vacua. They can give rise to decays of particles otherwise forbidden. Using data collected at the Pierre Auger Observatory, we search for signatures of such instanton-induced processes that would be suggestive of super-heavy particles decaying in the Galactic halo. These particles could have been produced during the post-inflationary epoch and match the relic abundance of dark matter inferred today. The nonobservation of the signatures searched for allows us to derive a bound on the reduced coupling constant of gauge interactions in the dark sector: α X≲ 0.09, for 10 9≲ M X/GeV< 10 19. Conversely, we obtain that, for instance, a reduced coupling constant α X= 0.09 excludes masses M X≳ 3× 10 13 GeV. In the context of dark matter production from …

Diseases transmitted by mosquito vectors, such as malaria, dengue, and Zika virus, pose significant healthcare challenges worldwide. Accurately estimating mosquito populations is vital for understanding transmission risks. Previous studies have explored the use of mosquito wingbeats for population surveys and control efforts. However, these methods require extensive data collection and annotation, which is time-consuming and resource-intensive. Additionally, laboratory-collected datasets lack biodiversity information from wild mosquitoes. To overcome these limitations, we propose an IoT system that automates the collection of mosquito wingbeat sounds in the field. Our system integrates with the Biogents BG-Counter 2 smart mosquito trap and incorporates a cost-effective acoustic sensing device. Initial assessments indicate successful integration, seamless data transmission, and satisfactory audio quality for …

The Pierre Auger Observatory investigates the properties of the highest-energy cosmic rays with unprecedented precision. The aim of the AugerPrime upgrade is to improve the sensitivity to the primary particle type. The improved mass sensitivity is the key to exploring the origin of the highest-energy particles in the Universe. The purpose of the Radio Detector (as part of AugerPrime) is to extend the sensitivity of the mass measurements to zenith angles in the range from 65 to 85. A radio antenna, sensitive in two polarization directions and covering a bandwidth from 30 to 80 MHz, will be added to each of the 1661 surface detector stations over the full 3000 km2 area, forming the world’s largest radio array for the detection of cosmic particles. Since November 2019, an engineering array comprised of ten stations has been installed in the field. The radio antennas are calibrated using the Galactic (diffuse) emission. The sidereal modulation of this signal is monitored continuously and is used to obtain an end-to-end calibration from the receiving antenna to the ADC in the read-out electronics. The calibration method and first results will be presented. The engineering array is also fully integrated in the data acquisition of the Observatory and records air showers regularly. The first air showers detected simultaneously with the water-Cherenkov detectors and the Radio Detectors will be presented. Simulations of the detected showers, based on the reconstructed quantities, have been conducted with CORSIKA/CoREAS. A comparison of the measured radio signals with those predicted by simulations exhibits satisfying agreement.

The ProtoDUNE-SP detector is a single-phase liquid argon time projection chamber (LArTPC) that was constructed and operated in the CERN North Area at the end of the H4 beamline. This detector is a prototype for the first far detector module of the Deep Underground Neutrino Experiment (DUNE), which will be constructed at the Sandford Underground Research Facility (SURF) in Lead, South Dakota, USA The ProtoDUNE-SP detector incorporates full-size components as designed for DUNE and has an active volume of 7× 6× 7.2 m^{3}. The H4 beam delivers incident particles with well-measured momenta and high-purity particle identification. ProtoDUNE-SP's successful operation between 2018 and 2020 demonstrates the effectiveness of the single-phase far detector design. This paper describes the design, construction, assembly and operation of the detector components.

The Pierre Auger Observatory [1] is the world’s largest cosmic ray observatory. It is located in the province of Mendoza, Argentina, near the town of Malargüe. One of the primary goals of the Observatory is to measure the energy spectrum of cosmic rays. The Observatory consists of two main parts, the array of surface detector stations (SD) that extends over 3000 km2 and the detector composed of 27 fluorescence telescopes (FD) that overlook the atmosphere above the array. These detectors operate both separately and also using a common trigger sequence in a hybrid regime. The energy spectrum of cosmic rays is measured using several detection techniques as explained in Section 2. Different techniques allow us to derive the energy spectrum in different energy ranges. The high-elevation Auger telescopes (HEAT), an extension of the FD, are used to obtain the spectrum at energies below 1017 eV. Between 1017 eV and 1018. 4 eV the SD with 750 m spacing provides the most precise measurement while, at the highest energies, the horizontally looking FD telescopes and the SD with 1500 m spacing are utilized. The energy spectrum measurements performed using the above mentioned techniques are then combined into a single estimate covering the energy range from 6 PeV up to the highest energies. Individual measurements, the combination procedure, and spectral features observed in the combined spectrum are discussed in Section 3.

The Auger Engineering Radio Array (AERA) is currently the largest array of radio antennas for the detection of cosmic rays, spanning an area of 17 km2 with 153 radio antennas, measuring in the energy range from 1017.0 to 1019.0 eV. It detects the radio emission of extensive air showers produced by cosmic rays in the 30− 80 MHz band. The cosmic-ray mass composition is a crucial piece of information in determining the sources of cosmic rays and their acceleration mechanisms. The depth of the shower maximum, Xmax, a probe for mass composition can be determined with a likelihood analysis that compares the measured radio-emission footprint on the ground to an ensemble of footprints from CORSIKA/CoREAS Monte-Carlo air shower simulations. These simulations are also used to determine the resolution of the method and to validate the reconstruction by identifying and correcting for systematic uncertainties. We will present the method for the reconstruction of the depth of the shower maximum, achieving a resolution of up to 15 g/cm2, show compatibility with the independent fluorescence detector reconstruction measured on an event-by-event basis, and show that the data taken over the past seven years with AERA shows a light cosmic-ray mass composition reconstruction in the energy range from 1017.5 to 1018.8 eV.

The energy spectrum of ultra-high-energy cosmic rays, UHECRs, undergoes a hardening at 5EeV called the ankle [1]. Above this energy, the flux has long been thought to be primarily extragalactic in origin [2]. Observation confirmed this through the recent discovery of a dipole anisotropy in the arrival directions of UHECRs with energies slightly above the ankle (> 8EeV)[3]. This is further supported by evidence of anisotropies occurring near the flux suppression at around 40 EeV [4]. Above the ankle, the mass composition of UHECRs is also best described as consisting of a mix of light, intermediate and high-mass primaries [5, 6]. A mixed composition in turn implies that, at fixed energies, each species will undergo differing deflections in magnetic fields. Additionally, due to energy-loss effects which depend on primary mass and charge, at a fixed energy the horizon of each species, and therefore potentially their source distributions, differ [7]. These give rise to the possibility of mass dependent anisotropies in the UHECR flux. More specifically, simulation using both the Jansson-Farrar, JF12 [8], and the Pshirkov, Tinyakov and Kronberg, PTK11 [9], models of the Galactic Magnetic Field, GMF, have shown that around a rigidity of∼ 6EV, the propagation of UHECRs in the GMF transitions from diffusive to ballistic [10]. From this, it is clear that as energy increases, the lighter, less charged, components of the flux will reach this threshold first, and therefore can be expected to display some degree of their source anisotropy in their local arrival directions. The heavier species however, would maintain a more isotropic distribution until much higher energies …

The study of the production of nuclei and antinuclei in pp collisions has proven to be a powerful tool to investigate the formation mechanism of loosely bound states in high-energy hadronic collisions. In this paper, the production of protons, deuterons and and their charge conjugates at midrapidity is studied as a function of the charged-particle multiplicity in inelastic pp collisions at TeV using the ALICE detector. Within the uncertainties, the yields of nuclei in pp collisions at TeV are compatible with those in pp collisions at different energies and to those in p–Pb collisions when compared at similar multiplicities. The measurements are compared with the expectations of coalescence and Statistical Hadronisation Models. The results suggest a common formation mechanism behind the production of light nuclei in hadronic interactions and confirm that they do not depend on the collision energy but …

A search for decays of pair-produced neutral long-lived particles (LLPs) is presented using 139 fb of proton-proton collision data collected by the ATLAS detector at the LHC in 2015-2018 at a centre-of-mass energy of 13 TeV. Dedicated techniques were developed for the reconstruction of displaced jets produced by LLPs decaying hadronically in the ATLAS hadronic calorimeter. Two search regions are defined for different LLP kinematic regimes. The observed numbers of events are consistent with the expected background, and limits for several benchmark signals are determined. For a SM Higgs boson with a mass of 125 GeV, branching ratios above 10% are excluded at 95% confidence level for values of times LLP mean proper lifetime in the range between 20 mm and 10 m depending on the model. Upper limits are also set on the cross-section times branching ratio for scalars with a mass of 60 GeV and for masses between 200 GeV and 1 TeV.

Searches are conducted for new spin-0 or spin-1 bosons using events where a Higgs boson with mass 125 GeV decays into four leptons (ℓ= e, μ). This decay is presumed to occur via an intermediate state which contains two on-shell, promptly decaying bosons: H→ XX/ZX→ 4ℓ, where the new boson X has a mass between 1 and 60 GeV. The search uses pp collision data collected with the ATLAS detector at the LHC with an integrated luminosity of 139 fb− 1 at a centre-of-mass energy= 13 TeV. The data are found to be consistent with Standard Model expectations. Limits are set on fiducial cross sections and on the branching ratio of the Higgs boson to decay into XX/ZX, improving those from previous publications by a factor between two and four. Limits are also set on mixing parameters relevant in extensions of the Standard Model containing a dark sector where X is interpreted to be a dark boson.

The recent observations of photons with energies of a few 1014 eV from decaying neutral pions, both from a direction coincident with a giant molecular cloud (HAWC J1825-134, Albert et al. 2021) and from the Galactic plane (Amenomori et al. 2021), provide evidence for an acceleration of cosmic rays to energies of several 1015 eV, and above, in the Galaxy. A dozen sources emitting photons with energies up to 1015 eV have even been reported (Cao et al. 2021a), and in at least one of them (LHAASO J2108+ 515, also in directional coincidence with a giant molecular cloud), these photons might have a hadronic origin (Cao et al. 2021b). Observations of these photons are key in probing the mechanisms of particle acceleration, completing the multi-messenger approach aimed at understanding the nonthermal processes producing cosmic rays. The detection of even higher-energy photons would be of considerable …

Correlations between mean transverse momentum [p T] and anisotropic flow coefficients v 2 or v 3 are measured as a function of centrality in Pb–Pb and Xe–Xe collisions at s NN= 5.02 TeV and 5.44 TeV, respectively, with ALICE. In addition, the recently proposed higher-order correlation between [p T], v 2, and v 3 is measured for the first time, which shows an anticorrelation for the presented centrality ranges. These measurements are compared with hydrodynamic calculations using IP-Glasma and T R ENTo initial-state shapes, the former based on the Color Glass Condensate effective theory with gluon saturation, and the latter a parameterized model with nucleons as the relevant degrees of freedom. The data are better described by the IP-Glasma rather than the T R ENTo based calculations. In particular, Trajectum and JETSCAPE predictions, both based on the T R ENTo initial state model but with different …

Neutral pion (π 0) and η meson production cross sections were measured up to unprecedentedly high transverse momenta (p T) in p–Pb collisions at s NN= 8.16 TeV. The mesons were reconstructed via their two-photon decay channel in the rapidity interval− 1.3< y< 0.3 in the ranges of 0.4< p T< 200 GeV/c and 1.0< p T< 50 GeV/c, respectively. The respective nuclear modification factor (R pPb) is presented for p T up to of 200 and 30 GeV/c, where the former was achieved by extending the π 0 measurement in pp collisions at s= 8 TeV using the merged cluster technique. The values of R pPb are below unity for p T< 10 GeV/c, while they are consistent with unity for p T> 10 GeV/c, leaving essentially no room for final state energy loss. The new data provide strong constraints for nuclear parton distribution and fragmentation functions over a broad kinematic range and are compared to model predictions as well as …

A search for new long-lived particles decaying to leptons using proton-proton collision data produced by the CERN LHC at = 13 TeV is presented. Events are selected with two leptons (an electron and a muon, two electrons, or two muons) that both have transverse impact parameter values between 0.01 and 10 cm and are not required to form a common vertex. Data used for the analysis were collected with the CMS detector in 2016, 2017, and 2018, and correspond to an integrated luminosity of 118 (113) fb in the ee channel (e and channels). The search is designed to be sensitive to a wide range of models with displaced e, ee, and final states. The results constrain several well-motivated models involving new long-lived particles that decay to displaced leptons. For some areas of the available phase space, these are the most stringent constraints to date.

This paper presents a search for decays of the Higgs boson with a mass of 125 GeV into a pair of new pseudoscalar particles, H→ a a, where one a-boson decays into a b-quark pair and the other into a muon pair. The search uses 139 fb− 1 of proton-proton collision data at a center-of-mass energy of s= 13 TeV recorded between 2015 and 2018 by the ATLAS experiment at the LHC. A narrow dimuon resonance is searched for in the invariant mass spectrum between 16 GeV and 62 GeV. The largest excess of events above the Standard Model backgrounds is observed at a dimuon invariant mass of 52 GeV and corresponds to a local (global) significance of 3.3 σ (1.7 σ). Upper limits at 95% confidence level are placed on the branching ratio of the Higgs boson to the b b μ μ final state, B (H→ a a→ b b μ μ), and are in the range 0.2–4.0× 10− 4, depending on the signal mass hypothesis.
