Minimal learning machine in anomaly detection from hyperspectral images
2020
Abstract. Anomaly detection from hyperspectral data needs computationally efficient methods to process the data when the data gathering platform is a drone or a cube satellite. In this study, we introduce a minimal learning machine for hyperspectral anomaly detection. Minimal learning machine is a novel distance-based classification algorithm, which is now modified to detect anomalies. Besides being computationally efficient, minimal learning machine is also easy to implement. Based on the results, we show that minimal learning machine is efficient in detecting global anomalies from the hyperspectral data with low false alarm rate.
Memory CD8+ T Cell Protection From Viral Reinfection Depends on Interleukin-33 Alarmin Signals
2019
Memory CD8+ cytotoxic T lymphocytes (CTLs) can protect against viral reinfection. However, the signals driving rapid memory CTL reactivation have remained ill-defined. Viral infections can trigger the release of the alarmin interleukin-33 (IL-33) from non-hematopoietic cells. IL-33 signals through its unique receptor ST2 to promote primary effector expansion and activation of CTLs. Here, we show that the transcription factor STAT4 regulated the expression of ST2 on CTLs in vitro and in vivo in primary infections with lymphocytic choriomeningitis virus (LCMV). In the primary antiviral response, IL-33 enhanced effector differentiation and antiviral cytokine production in a CTL-intrinsic manne…
Management of odonto-stomatological emergencies during the COVID-19 alarm state in dental clinics in the Autonomous Community of Madrid (CAM), Spain:…
2020
Background Odontology practice has been severely compromised by the pandemic caused by COVID-19 and Spain is one of the countries with higher incidence. Our aim with this study is to find out the number of cases and type of odonto-stomatological emergencies (OSE) treated in four dental clinics of the Madrid capital area and region (CAM) in the period covered between March 17th and 4th of May. Material and Methods We search the cases in the demographic/epidemiological databases of the CAM regional government and the Illustrious Official College of Dentists and Stomatologists of the First Region (Madrid). Results We found that the most prevalent pathology was acute apical periodontitis wherea…
Telemonitoring in chronic pain management using smartphone apps: a randomized controlled trial comparing usual assessment against app-based monitorin…
2020
Background. The usefulness of mHealth in helping to target face-to-face interventions for chronic pain more effectively remains unclear. In the present study, we aim to test whether the Pain Monitor mobile phone application (app) is well accepted by clinicians, and can help improve existent medical treatments for patients with chronic musculoskeletal pain. Regarding this last goal, we compared three treatment conditions, namely usual treatment, usual treatment with an app without alarms and usual treatment with an app with alarms. All treatments lasted one month. The three treatments were compared for all outcomes, i.e., pain severity and interference, fatigue, depressed mood, anxiety and a…
Informasjonsflyt ved mottak og respons på trygghetsalarmer : en casestudie for å undersøke hvilken betydning tilgang på informasjon og informasjonsfl…
2016
Masteroppgave i helse- og sosialinformatikk- Universitetet i Agder, 2016 The theme of this study is security alarms and information flow. The background for the study is estimates regarding an upcoming growing number of security alarms in municipal healthcare services, recommendations on the transition from analogue to digital security alarms, and reports on the current organization of the safety alarms of varying quality and low efficiency (Frantzen, 2014; Fensli, 2015 Kvernland-Berg, 2014). Purpose The aim of this study was to find what importance access to information and information flow had in the working process with security alarms for a future-oriented health services. Method The su…
GW170817: Observation of Gravitational Waves from a Binary Neutron Star Inspiral
2017
On August 17, 2017 at 12-41:04 UTC the Advanced LIGO and Advanced Virgo gravitational-wave detectors made their first observation of a binary neutron star inspiral. The signal, GW170817, was detected with a combined signal-to-noise ratio of 32.4 and a false-alarm-rate estimate of less than one per 8.0×104 years. We infer the component masses of the binary to be between 0.86 and 2.26 M, in agreement with masses of known neutron stars. Restricting the component spins to the range inferred in binary neutron stars, we find the component masses to be in the range 1.17-1.60 M, with the total mass of the system 2.74-0.01+0.04M. The source was localized within a sky region of 28 deg2 (90% probabili…
Crónica sobre la problemática jurídica de los repartidores de comida a domicilio durante el estado de alarma
2020
En este artículo se realiza una crónica que analiza las implicaciones jurídico- laborales de los obstáculos y conflictos a los que se han enfrentado los trabajadores de las principales empresas de reparto de comida a domicilio durante los dos primeros meses de estado de alarma que, como consecuencia de la crisis sanitaria de la Covid-19, fue decretado en España el 14 de marzo de 2020. Partiendo del primigenio problema de los falsos autónomos, se abordan cuestiones como las dificultades para acceder a las prestaciones extraordinarias, la falta de medidas de protección de la salud, la reducción drástica de su remuneración, la carencia de titularidad del derecho de huelga o la prohibición de m…
Using Temporal Expectation to Assess Auditory Streaming in Mice
2018
Auditory streaming is the process by which environmental sound is segregated into discrete perceptual objects. The auditory system has a remarkable capability in this regard as revealed in psychophysical experiments in humans and other primates. However, little is known about the underlying neuronal mechanisms, in part because of the lack of suitable behavioural paradigms in non-primate species. The mouse is an increasingly popular model for studying the neural mechanisms of perception and action because of the range of molecular tools enabling precise manipulation of neural circuitry. Here we present a novel behavioural task that can be used to assess perceptual aspects of auditory streami…
