Demo - A Cell-level Traffic Generator for LoRa Networks
2017
In this demo we present and validate a LoRa cell traffic generator, able to emulate the behavior of thousands of low-rate sensor nodes deployed in the same cell, by using a single Software Defined Radio (SDR) platform. Differently from traditional generators, whose goal is creating packet flows which emulate specific applications and protocols, our focus is generating a combined radio signal, as seen by a gateway, given by the super-position of the signals transmitted by multiple sensors simultaneously active on the same channel. We argue that such a generator can be of interest for testing different network planning solutions for LoRa networks.
IoT gateway and architecture developing for Realtime Location Systems
2021
Epidemioloģiskā situācija pasaulē prasa cilvēku mijiedarbības izpēti telpā. Valdības projekta “Multidisciplināras pieejas izmantošana, lai aprakstītu SARS-CoV-2 epidemioloģisko izplatību Latvijā un izstrādātu efektīvas stratēģijas turpmāko epidēmiju kontrolei” ietvaros tika izstrādāts risinājums attālumu starp cilvēkiem novērošanai, izmantojot UWB tehnoloģiju. Šī dokumenta ietvaros tiks izstrādāta reāllaika lokalizācijas sistēmu vārtejas programmatūra un arhitektūra. Mērķis ir izstrādāt spēcīgu un elastīgu programmatūru vārtejai, lai apkopotu atrašanās vietas datus no sensoriem un saglabātu tos datu bāzēs.

Life-course leisure-time physical activity trajectories in relation to health-related behaviors in adulthood: the Cardiovascular Risk in Young Finns …
2021
Background Evidence on whether leisure-time physical activity (LTPA) facilitates individuals’ adoption of multiple healthy behaviors remains scarce. This study investigated the associations of diverse longitudinal LTPA trajectories from childhood to adulthood with diet, screen time, smoking, binge drinking, sleep difficulties, and sleep duration in adulthood. Methods Data were drawn from the Cardiovascular Risk in Young Finns Study. Participants were aged 9–18 years (N = 3553; 51% females) in 1980 and 33–49 years at the latest follow-up in 2011. The LTPA trajectories were identified using a latent profile analysis. Differences in self-reported health-related behaviors across the LTPA trajec…
Effect of adolescent exposure to MDMA and cocaine on acquisition and reinstatement of morphine-induce CPP
2007
It is well known that an elevated percentage of ecstasy users also consume cocaine. Recently, it has been reported that a high frequency of heroin smokers first consumed heroin under the effects of ecstasy with the hope of reducing the stimulant effects of the latter drug. The aim of the present study was to evaluate the effect of exposure to MDMA and cocaine during adolescence on morphine-induced conditioned place preference (CPP) and reinstatement in adulthood. In the first experiment, adolescent mice were exposed to six injections of MDMA and three weeks later their response to the reinforcing properties of 40 mg/kg of morphine was evaluated using the CPP paradigm. All the treatment grou…
The MoSGrid Science Gateway – A Complete Solution for Molecular Simulations
2014
The MoSGrid portal offers an approach to carry out high-quality molecular simulations on distributed compute infrastructures to scientists with all kinds of background and experience levels. A user-friendly Web interface guarantees the ease-of-use of modern chemical simulation applications well established in the field. The usage of well-defined workflows annotated with metadata largely improves the reproducibility of simulations in the sense of good lab practice. The MoSGrid science gateway supports applications in the domains quantum chemistry (QC), molecular dynamics (MD), and docking. This paper presents the open-source MoSGrid architecture as well as lessons learned from its design.
Título: Dieta, drogas y cerebro. Subtítulo:¿Podría ser la comida ultraprocesada una puerta de entrada a la adicción?
2020
Los alimentos altos en grasas y azucares nos resultan placenteros porque producen una estimulacion del circuito de recompensa, el mismo que activan las drogas. En un contexto en el que una dieta no saludable y el consumo de drogas son habituales desde la adolescencia, es importante investigar cuales son sus consecuencias. Este articulo presenta la relacion existente entre la ingesta de comida especialmente sabrosa, el sistema de refuerzo cerebral y el consumo de drogas. Estudios con modelos animales han mostrado que la ingesta intermitente de dieta rica en grasa durante la adolescencia incrementa el consumo de cocaina y etanol. La investigacion reciente evidencia el papel fundamental de la …
Probing the gateway to superheavy nuclei in cranked relativistic Hartree-Bogoliubov theory
2003
The cranked relativistic Hartree+Bogoliubov theory has been applied for a systematic study of the nuclei around 254No, the heaviest nuclei for which detailed spectroscopic data are available. The deformation, rotational response, pairing correlations, quasi-particle and other properties of these nuclei have been studied with different relativistic mean field (RMF) parametrizations. For the first time, the quasi-particle spectra of odd deformed nuclei have been calculated in a fully self-consistent way within the framework of the RMF theory. The energies of the spherical subshells, from which active deformed states of these nuclei emerge, are described with an accuracy better than 0.5 MeV fo…

Il ruolo delle città e dei territori-snodo nel policentrismo reticolare
2014
Riconoscendo nel policentrismo il modello insediativo che contraddistingue l’Unione Europea e nell’armatura delle città di secondo livello potenzialità alternative di sviluppo, la cui forza propulsiva è intrinseca nel loro specifico milieu e nelle differenze che alimentano le opportunità di connessione, si ritiene che le città debbano diventare generatori di flussi, produttori di identità, economie e nuove geografie, creare dinamismo urbano e interazioni spaziali capaci di attrarre reti locali e globali. È necessario, pertanto, definire meglio il ruolo delle città, le modalità di interazione e di sviluppo nel più ampio contesto territoriale.
