Jauniešu psihopātijas iezīmju saistība ar sevis prezentēšanas paradumiem sociālajā vietnē Instagram
2020
Pētījuma mērķis bija noskaidrot, vai pastāv saistība starp jauniešu psihopātijai raksturīgām iezīmēm un sociālās vietnes “Instagram” lietošanas paradumiem sevis prezentēšanā, un, ja pastāv, kāda tā ir. Pētījumā piedalījās 69 pusaudži vecumā no 14 līdz 18 gadiem, 52 meitenes un 17 zēni, kuriem ir izveidoti un aktīvi sociālās vietnes “Instagram” personīgie profili. Vidējais respondentu vecums bija 16 gadi, un vidējais “Instagram” lietošanas ilgums bija 5 gadi. Pusaudžu psihopātisko iezīmju mērīšanai tikai izmantota Jauniešu psihopātisko iezīmju aptauja (Youth Psychopathic Traits Inventory, YPI; Andershed, Kerr, Stattin, & Levander, 2002), kuru sava maģistra darba ietvaros latviešu valodā adap…
Upgrade of ALICE forward detectors
2019
ALICE will upgrade its subsystems in 2019−2020 to fully benefit from the increased collision rate and luminosity of the LHC at CERN. Two new forward detectors will be installed at the core of ALICE: the Fast Interaction Trigger (FIT) and the Muon Forward Tracker (MFT). Additionally, during the shutdown between Run 3 and Run 4, there will be an opportunity to install the Forward Calorimeter (FoCal). This paper describes these new forward detectors, their physics justification and goals, selected design features along with performance of detector prototypes and simulated performance figures. peerReviewed
Valodas elementu lietojuma variācijas Anglijas un Skotijas dienas laikrakstu tekstos
2019
Laikraksti ir pastāvējuši jau gadsimtiem ilgi un vēsturiski tie ir attīstījuši dažādus veidus, kas attiecināmi uz laikrakstu izmēru, mērķauditoriju, aprakstītajiem notikumiem; tomēr visiem laikrakstiem ir noteikti struktūras un satura pamatprincipi, pēc kuriem tie vadās, lai saglabātu rakstīta teksta tipiskās pazīmes visā pasaulē. Šī darba mērķis ir izpētīt valodas lietojuma variācijas dienas laikrakstu tekstos, kas parādītu, kā atšķiras tematiski atbilstošās nodaļas un valodas reģistra variācijas dažādu tipu laikrakstos dažādos publicēšanas apgabalos. Metodes: Trīs britu un skotu laikraksti ar plašāko lasītāju publiku tika izvēlēti, lai tajos noteiktu leksisko blīvumu un dažādību divās tem…
El aprendizaje de los rasgos fonopragmáticos del enfado en español como lengua extranjera
2020
espanolIdentificar la expresion de enfado en una lengua extranjera y reproducirla con adecuacion y precision son destrezas cuya relevancia y falta de propuestas satisfactorias han sido senaladas por las investigaciones sobre la ensenanza de emociones (Dewaele, 2010; Toya & Kodis, 1996). Este trabajo combina la identificacion de carencias en la didactica de la entonacion emocional con el analisis de muestras espontaneas de enfado como base de unas pautas didacticas para introducir la ensenanza contextualizada de la expresion de enfado en espanol. A traves de muestras de un corpus coloquial, se identifican los rasgos caracteristicos de la expresion de enfado en espanol. Una seleccion de rasgo…
A new definition for metabolic dysfunction-associated fatty liver disease: An international expert consensus statement
2020
The exclusion of other chronic liver diseases including “excess” alcohol intake has until now been necessary to establish a diagnosis of metabolic dysfunction-associated fatty liver disease (MAFLD). However, given our current understanding of the pathogenesis of MAFLD and its rising prevalence, “positive criteria” to diagnose the disease are required. In this work, a panel of international experts from 22 countries propose a new definition for the diagnosis of MAFLD that is both comprehensive and simple, and is independent of other liver diseases. The criteria are based on evidence of hepatic steatosis, in addition to one of the following three criteria, namely overweight/obesity, presence …
HCV genotype 1 subtypes (1a and 1b): similarities and differences in clinical features and therapeutic outcome.
2015
Aim: To evaluate similarities and differences in HCV-1 subtypes 1a and 1b in the presenting clinical features and the response to peg-interferon and ribavirin (Peg/RIBA).Patients and methods: A total of 1,233 naïve patients with HCV genotype-1 infection, 159 (13 %) with subtype 1a and 1,074 (87 %) with subtype 1b were treated with Peg-IFN/RIBA at 12 Italian centers. Covariates included in the logistic model were age, gender, BMI, serum alanine aminotransferase, serum gamma-glutamiltranspeptidase (γGT), platelets counts, liver fibrosis, the occurrence of type 2 diabetes, baseline viremia, and IL28B genotype.Results: At multivariate analysis, baseline characteristics differentiating patients …
Clinical, immunological, and molecular analysis in a large cohort of patients with X-linked agammaglobulinemia: an Italian multicenter study
2002
A questionnaire-based retrospective clinical and immunological survey was conducted in 73 males with a definite diagnosis of X-linked agammaglobulinemia based on BTK sequence analysis. Forty-four were sporadic and 29 familial cases. At December 2000, the patients' ages ranged from 2 to 33 years; mean age at diagnosis and mean duration of follow-up were 3.5 and 10 years respectively. After the mid-1980s all but 2 were on intravenous immunoglobulin (IVIG) substitution therapy, with residual IgG >500 mg/dl in 94% of the patients at the time of enrollment. Respiratory infections were the most frequent manifestation both prior to diagnosis and over follow-up. Chronic lung disease (CLD) was prese…
Prognostic Factors in Childhood Anaplastic Large Cell Lymphoma: Long Term Results of the International ALCL99 Trial
2020
With the aim of describing the long-term follow-up and to define the prognostic role of the clinical/pathological/molecular characteristics at diagnosis for childhood, adolescent and young adults affected by anaplastic large cell lymphoma (ALCL), we analyzed 420 patients aged up to 22 years homogeneously treated within the international ALCL99 trial. The 10-year progression free survival (PFS) was 70% and overall survival was 90%, rare late relapses occurred but no secondary malignancies were reported. Among clinical/pathological characteristics, only patients presenting a small cell/lymphohistiocytic (SC/LH) pattern were independently associated with risk of failure (hazard ratio = 2.49). …

Antiferromagnetic Insulatronics: spintronics without magnetic fields
2021
While known for a long time, antiferromagnetically ordered systems have previously been considered, as expressed by Louis Neel in his Nobel Prize Lecture, to be “interesting but useless”. However, since antiferromagnets potentially promises faster operation, enhanced stability with respect to interfering magnetic fields and higher integration due to the absence of dipolar coupling, they could potentially become a game changer for new spintronic devices. The zero net moment makes manipulation using conventional magnetic fields challenging. However recently, these materials have received renewed attention due to possible manipulation based on new approaches such as photons or spin-orbit torqu…
