Toimittajat turvallisuussalaisuuden paljastajina
2023
Helsingin käräjäoikeus on antanut tuomion toimittajiin kohdistuneesta turvallisuussalaisuuden paljastamista koskevassa rikosasiassa 27.1.2023 R 2021/8393. Oliko Helsingin Sanomien 16.12.2017 artikkelissa julkaistu tietoja sekä jatkoartikkeleissa yritetty julkistaa sotilastiedustelusta tietoja, jotka on säädetty viranomaisten toiminnan julkisuudesta annetun lain 24 §:n 1 momentin 10 kohdan nojalla salassa pidettäviksi? Sekä syyttäjä että vastaajat ovat ilmoittaneet tyytymättömyyttä tuomioon ja aikovat valittaa siitä. nonPeerReviewed
Momentum-space structure of surface states in a topological semimetal with a nexus point of Dirac lines
2016
Three-dimensional topological semimetals come in different variants, either containing Weyl points or Dirac lines. Here we describe a more complicated momentum-space topological defect where several separate Dirac lines connect with each other, forming a momentum-space equivalent of the real-space nexus considered before for helium-3. Close to the nexus the Dirac lines exhibit a transition from type I to type II lines. We consider a general model of stacked honeycomb lattices with the symmetry of Bernal (AB) stacked graphite and show that the structural mirror symmetries in such systems protect the presence of the Dirac lines, and also naturally lead to the formation of the nexus. By the bu…
Dirakův kužel a pseudogapped hustota stavů v topologické polovině Heuslerovy sloučeniny YPtBi
2016
Topologické izolátory (Tis) jsou zajímavé materiály, které vykazují nebývalé vlastnosti. . Zde jsme prozkoumali sloučeniny YPtBi jako příklad ze třídy polovu-Heuslerových materiálů. Topological insulators (TIs) are exciting materials, which exhibit unprecedented properties, such as helical spinmomentum locking, which leads to large torques for magnetic switching and highly efficient spin current detection. Here we explore the compound YPtBi, an example from the class of half-Heusler materials, for which the typical band inversion of topological insulators was predicted. We prepared this material as thin films by conventional cosputtering from elementary targets. By in situ time-of-flight mo…
Polyphenols Epigallocatechin Gallate and Resveratrol, and Polyphenol-Functionalized Nanoparticles Prevent Enterovirus Infection through Clustering an…
2021
To efficiently lower virus infectivity and combat virus epidemics or pandemics, it is important to discover broadly acting antivirals. Here, we investigated two naturally occurring polyphenols, Epigallocatechin gallate (EGCG) and Resveratrol (RES), and polyphenol-functionalized nanoparticles for their antiviral efficacy. Concentrations in the low micromolar range permanently inhibited the infectivity of high doses of enteroviruses (107 PFU/mL). Sucrose gradient separation of radiolabeled viruses, dynamic light scattering, transmission electron microscopic imaging and an in-house developed real-time fluorescence assay revealed that polyphenols prevented infection mainly through clustering of…
Siracusa e la Sicilia nel III secolo a.C.: problemi conoscitivi e proposte di lettura dei fenomeni urbanistici e architettonici
2017
L’evoluzione sotto il profilo urbanistico e architettonico delle città di Sicilia nel III secolo a.C. può essere compresa solo a partire da un esame delle evidenze di Siracusa, la maggiore città dell’Occidente greco-ellenistico e capitale di un regno che sotto Agatocle e soprattutto sotto Ierone II vede un prodigioso sviluppo non solo per l’estensione dell’area urbana, ma soprattutto per la riconfigurazione dello spazio cittadino in forme innovative, destinate a influenzare in maniera decisiva anche le città minori del regno e dell’Oriente dell’isola, e successivamente anche dei comprensori centro-occidentali e settentrionali. L’aspetto più importante e programmatico nella rimodulazione del…

Effects of mild aerobic exercise training on the diaphragm in mdx mice
2016
Mild endurance exercise training positively affects limb skeletal muscle in the mdx mice model of Duchenne Muscular Dystrophy (DMD). However, few and controversial data are available on the effects of mild exercise training on the diaphragm of mdx mice. The diaphragm was examined in mdx and wild type mice either under sedentary conditions (mdx-SD, WT-SD) or during mild exercise training (mdx-EX, WT-EX). At baseline and after 30 and 45 days of training (5 d/wk for 6 weeks), diaphragm muscle morphology and Cx39 protein were assessed. In addition, tissue levels of the chaperonin Hsp60 were measured at the same time points in gastrocnemius, quadriceps and diaphragm in each experimental group. A…
