Analysis of MAC-level throughput in LTE systems with link rate adaptation and HARQ protocols
2015
LTE is rapidly gaining momentum for building future 4G cellular systems, and real operational networks are under deployment worldwide. To achieve high throughput performance, in addition to an advanced physical layer design LTE exploits a combination of sophisticated mechanisms at the radio resource management layer. Clearly, this makes difficult to develop analytical tools to accurately assess and optimise the user perceived throughput under realistic channel assumptions. Thus, most existing studies focus only on link-layer throughput or consider individual mechanisms in isolation. The main contribution of this paper is a unified modelling framework of the MAC-level downlink throughput of …
Crystal field and magnetism with Wannier functions: Rare-earth doped aluminum garnets
2015
Using the recently developed method we calculate the crystal field parameters in yttrium and lutetium aluminum garnets doped with seven trivalent Kramers rare-earth ions. We then insert calculated parameters into the atomic-like Hamiltonian taking into account the electron-electron, spin-orbit and Zeeman interactions and determine the multiplet splitting by the crystal field as well as magnetic $\hat{g}$ tensors. We compare calculated results with available experimental data.
Alfred Schütz: un’interpretazione sociologica di confine
1996
Il saggio riprende l'analisi schutziana concernente le strutture significative della vita quotidiana, per evidenziare come le "realtà multiple" potenziano, mediante il "principio di rilevanza", la percezione sinottica dei singoli soggetti e la conoscenza come esperienza trascendentale.
Skala Niesprawności Neurologicznej Szpitala Guy jako istotne narzędzie do oceny objawów występujących u osób z SM
2017
Skala Niesprawności Neurologicznej Szpitala Guy (GNDS, The Guy’s Neurological Disability Scale) jest istotnym narzędziem służącym do pomiaru niepełnosprawności u osób ze stwardnieniem rozsianym. Służy ona do określenia poziomu funkcjonowania w dwunastu ważnych obszarach. Celem obecnych badań było opracowanie polskiej wersji językowej skali GNDS i sprawdzenie jej trafności, rzetelności oraz przydatności do oceny niepełnosprawności występującej u osób ze stwardnieniem rozsianym. Grupę badaną stanowiło 175. pacjentów z rozpoznaniem stwardnienia rozsianego. W badaniu wykorzystano Rozszerzoną Skalę Niewydolności Ruchowej – EDSS, Skalę Niesprawności Neurologicznej Szpitala Guy – GNDS, Skalę Akcep…
Clinical Onset and Multiple Sclerosis Relapse after SARS-CoV-2 Infection
2021
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been associated with several neurological disorders including headache, facial palsy, encephalitis, stroke, demyelinating disorders. The present report will discuss cases of multiple sclerosis (MS) onset and relapse both beginning early after SARS-CoV-2 infection. In both cases, magnetic resonance imaging (MRI) showed widespread bilateral subcortical and periventricular active lesions. Serum IgG against SARS-CoV-2 Spike antigens confirmed seroconversion with titers that are considered not definitely protective against possible reinfection. We hypothesize that SARS-CoV-2 infection, as previously reported for other vir…
Off-Adherence Keeping (OAK) observational study: intentional off-adherence immunomodulatory multiple sclerosis treatment
2022
Aims: To evaluate how improved treatment adherence with a lower-frequency regimen/treatment of intramuscular (IM) IFN beta-1a impacts therapeutic effectiveness in relapsing-remitting multiple sclerosis (MS) patients switching from a higher-frequency injectable regimen/treatment. Patients & methods: Italian patients with relapsing-remitting MS and prior poor adherence to high-frequency injectable treatments (n = 181) were followed for 24 months after starting IM IFN beta-1a. Results: During the study, 97.4% of patients were treatment adherent; 22.1% of patients reported a relapse. The estimated probability of remaining relapse-free after 2 years was 78%. A high dropout rate (52.5%) led t…
Verb-Second and (micro)-variation in two Rhaeto-Romance varieties of Northern Italy.
2018
Rhaeto-Romance varieties are the only present-day Romance varieties which exhibit the Verb Second constraint (Benincà 1994, Poletto 2002, Salvi 2010). In this chapter we examine two properties typically ascribed to the Verb Second phenomenon, subject-finite verb inversion and restrictions on the co-occurrence of multiple constituents in the sentence-initial position, in two Rhaeto-Romance varieties spoken in South Tyrol (Province of Bolzano, Northern Italy). We demonstrate that both varieties behave like Verb-Second languages as far as both phenomena are concerned, but exhibit a specific Verb-Second system governed by the interplay between syntactic and discourse constraints which differs f…
Kinetics of Renal Function during Induction in Newly Diagnosed Multiple Myeloma: Results of Two Prospective Studies by the German Myeloma Study Group…
2021
Background: Preservation of kidney function in newly diagnosed (ND) multiple myeloma (MM) helps to prevent excess toxicity. Patients (pts) from two prospective trials were analyzed, provided postinduction (PInd) restaging was performed. Pts received three cycles with bortezomib (btz), cyclophosphamide, and dexamethasone (dex
Analysis of multiple intelligences and creativity in university students
2018
espanolResumen: Un reto de la educacion actual es formar a alumnos competentes para desenvolverse en una sociedad diversa y dinamica. El cociente intelectual no es suficiente para garantizar el exito academico ni profesional (Extremera & Fernandez-Berrocal, 2006) y deben considerarse aspectos cognitivos, sociales y emocionales. El objetivo del estudio fue analizar el grado alcanzado en estudiantes universitarios de trabajo social en las inteligencias multiples, inteligencia emocional, creatividad y rendimiento academico, asi como su relacion y las diferencias en funcion del sexo y el curso en una muestra de 100 estudiantes. Se encontraron diferencias significativas en funcion del curso y re…
Optimal Resource Allocation in Multi-Hop Networks: Contention vs. Scheduling
2014
CSMA/CA (Carrier Sense Multiple Access/Collision Avoidance) is actually the most used method in ad-hoc networks for transmitting on a contending medium, even if it shows poor performance in presence of hidden nodes. To increase performance, we propose an algorithm that combines CSMA and TDMA (Time Division Multiple Access) approaches. The adopted solution consists of grouping contending nodes in non-interfering subsets and granting a different numbers of time slots to different groups, while using the CSMA to manage medium access among nodes belonging to the same subset. An optimization procedure to assign the time slots to each subset of nodes and to find an equilibrium between contention …
