Sull'inquadramento sistematico delle obbligazioni nella Parafrasi di Teofilo (e nelle Istituzioni giustinianee)
2016
The contribution deals with the origin of the particular place assigned in the Paraphrase of Theophilos to Obligations in relation to the Institutional System ‘personae-res-actiones’. The Author suggests that the displacement of Obligations from the field of the res to the field of the actiones and the representation of Obligations as “mothers of actions”, instead of deriving from an existing idea of Theophilos or from a general byzantine view, is influenced by some passages of the Justinian’s Institutions.
The usefulness of Olanzapine plasma concentrations in monitoring treatment efficacy and metabolic disturbances in first-episode psychosis
2021
Introduction: The role of Olanzapine therapeutic drug monitoring is controversial. The present study explores the associations of Olanzapine plasma concentrations with clinical response and metabolic side effects in first episode psychosis (FEP) after 2 months of treatment. Methods: Forty-seven patients were included. Improvement in clinical symptomatology was assessed using the PANSS. Metabolic assessment included weight, blood pressure, waist circumference, blood glucose, total cholesterol, high-density lipoprotein, low-density lipoprotein, and triglycerides. Results: The Olanzapine plasma concentrations after 2 months of treatment were positively correlated with weight gain (r = 0.49, p …
Course of weight gain and metabolic abnormalities in first treated episode of psychosis: the first year is a critical period for development of cardi…
2014
Data on the long-term metabolic side-effects associated with antipsychotics are scarce. Prospective longitudinal studies in medication-naive patients with a first episode of psychosis are a valuable source of information as they provide an assessment prior to the antipsychotic exposure and minimize the effect of potential confounding factors. The aim of this study was to assess the course of weight gain and the incidence of metabolic abnormalities during the first 3 yr of antipsychotic treatment. Data were collected from a cohort of 170 first-episode psychosis patients. They were randomly assigned to haloperidol (32%); olanzapine (32%) and risperidone (36%). The dose used was flexible. The …
Polymer/Perovskite Amplifying Waveguides for Active Hybrid Silicon Photonics
2015
The emission properties of hybrid halide perovskites are exploited to implement a stable and very low power operation waveguide optical amplifier integrated in a silicon platform. By optimizing its design with a poly(methyl methacrylate) (PMMA) encapsulation, this novel photonic device presents a net gain of around 10 dB cm−1 and 3–4 nm linewidth with an energy threshold as low as 2 nJ pulse−1 and exhibiting no degradation after one year. This work was supported by Generalitat Valenciana (Project No. ISIC/2012/008), the Universitat Jaume I (Project No. 12I361.01/1), Spanish MINECO (Projects Nos. MAT2013-47192-C3-1-R and TEC2014-53727-C2-1-R) and EU-NAVOLCHI (Project No. 288869).
Optimization of semiconductor halide perovskite layers to implement waveguide amplifiers
2017
Semiconductor organometallic halide (CH 3 NH 3 PbX 3 , X=Cl, Br, I) perovskites (HPVK) have been emerged as a potential gain media to construct a new generation of active photonic devices. Indeed, during the last three years a significant effort has been carried out to implement HPVK-based optical amplifiers or lasers with improved quality factors. In particular, minimization of the threshold of stimulated emission has been an important concern to decrease the power consumption, and hence to enhance the performances of the device. For this purpose strategies include a suitable integration of the semiconductor in a photonic structure, or the optimization of the material. Here we propose a no…
Halide perovskite amplifiers integrated in polymer waveguides
2016
Semiconductor organometallic halide perovskites (CH 3 NH 3 PbX 3 , X=Cl, Br, I) (HPVK) have emerged as a new promising material able to improve the optoelectronic technology performance. Although this material has mostly been applied to improve the efficiency of photovoltaic devices, it also shows amazing properties for photonic applications. In particular, HPVK exhibits high photoluminescence (PL) quantum yield (up to 70%) at room temperature together with a tunable band-gap controlled by its chemical composition. In addition, since HPVKs is deposited in solution at room conditions, it can be easily incorporated in different photonic structures to efficiently exploit its emission propertie…
On the optimal design of multi-stage cascaded transistor amplifiers with noise, gain and mismatch constraints
2007
The problem of evaluating the optimal performances of cascaded, unbalanced, multi-stage transistor amplifiers is addressed. In particular, a theoretically rigorous approach is proposed for the determination of a family of Optimal Design Curves (ODC's) which express the best noise-gain tradeoff that can be achieved - at each frequency and device operating condition - when a simultaneous constraint on amplifier input VSWR is accounted for. Such curves can be used as a more meaningful starting point in practical amplifier design in place of the approximate calculations so far employed for target performance or optimization goals determination.
Web-based framework for displaying environmental sensor data in organizations

Iekštelpu gaisa kvalitātei ir nemainīgi liela nozīme cilvēka ikdienas dzīvē. Cilvēki, kas lielāko dienas daļu pavada iekštelpās, piemēram, ofisā, jūt telpas gaisa kvalitātes ietekmi uz veselību un pašsajūtu. Telpas gaisa kvalitātes kontrole ir aktuāla problēma iestādēs, kas nav aprīkotas ar telpu gaisa automatizētu ventilāciju. Darbā aplūkoti risinājumi, kurus iespējams ierīkot iestādēs bez automatizētas ventilācijas sistēmas. Darbs tiek izstrādāts VPP “COVID-19 seku mazināšanai” projekta 6.6. ietvaros, kā rezultātā darba autors piedāvā savu risinājumu, lai uzraudzītu telpu gaisa kvalitāti organizācijās. Praktiskajā daļā realizēts reāls, strādājošs risinājums, kas ļauj veidot organizāciju t…
A Smartphone App to Promote Healthy Weight Gain, Diet, and Physical Activity During Pregnancy (HealthyMoms): Protocol for a Randomized Controlled Tri…
2019
BACKGROUND: Excessive gestational weight gain is common and associated with adverse outcomes both in the short and long term. Although traditional lifestyle-based interventions have shown to mitigate excess gestational weight gain, little is known about whether mobile Health (mHealth) apps can promote healthy weight gain, diet, and physical activity during pregnancy. OBJECTIVE: The primary aim of the HealthyMoms trial is to determine the effectiveness of a smartphone app (HealthyMoms) for mitigating excess gestational weight gain during pregnancy. Secondary aims are to determine the effectiveness of the app on dietary habits, physical activity, body fatness, and glycemia during pregnancy. M…
