Three-dimensional core-collapse supernovae with complex magnetic structures: I. Explosion dynamics
2021
Magnetic fields can play a major role in the dynamics of outstanding explosions associated to violent events such as GRBs and hypernovae, since they provide a natural mechanism to harness the rotational energy of the central proto-neutron star and power relativistic jets through the stellar progenitor. As the structure of such fields is quite uncertain, most numerical models of MHD-driven core-collapse supernovae consider an aligned dipole as initial magnetic field, while the field's morphology can actually be much more complex. We present three-dimensional simulations of core-collapse supernovae with more realistic magnetic structures, such as quadrupolar fields and, for the first time, an…
Changes in the receptor profile of the lower urinary tract in the aging male
2004
Benign prostatic hyperplasia (BPH) is one of th e most common effects of aging in men. Epidemiologists estimate that about one quarter of all men over 50 years of age suffer from BPH-derived voiding symptoms. Future demographic developments, with higher relative shares of older people, will increase the socioeconomic impact of this disease. Polder et al. (1994) calculated for the Netherlands that the treatment costs of BPH will double by 2035. Office visits for BPH related symptoms increased in the USA from 1.4 million in 1990 to 6 million in 1995, reflecting the increased public awareness of the problem and the increased desire for treatment (Kaplan et al. 1996).
Leikitään ja keskitytään : tukea itsesäätelyyn
2022
Leikitään ja keskitytään -hankkeessa tuettiin perheitä, joissa 3–5-vuotiaalla lapsella oli tarkkaamattomuuteen ja ylivilkkauteen liittyviä haasteita. Keskeinen tuen väline oli vanhemman ja lapsen yhteinen, päivittäinen leikki. Toiminta oli tarkoitettu varhaisen vaiheen ennaltaehkäiseväksi ja melko lyhyeksi tueksi. Leikitään ja keskitytään -hankkeessa leikittiin tuttuja leikkejä, muun muassa piirrettiin, pelattiin erilaisia pelejä ja sääntöleikkejä sekä tehtiin rentoutumisharjoituksia. Leikeissä, aikuisen rinnalla ja avustamana, lapset pääsivät harjoittelemaan toiminnanohjauksen taitoja, kuten vuoron odottamista, tarkkaavuuden kohdentamista tai toiminnan vauhdin säätelyä. Keskeistä oli vanhe…

Vascular Risk Factors in Mild Cognitive Impairment Subtypes
2007
<i>Background and Aim:</i> To investigate the role of vascular risk factors in different subtypes of mild cognitive impairment (MCI) in a multicentric, clinic-based, cross-sectional study. <i>Methods:</i> Two-hundred and seven subjects with MCI were included in the study: 33 with single non-memory MCI (snmMCI), 42 with multiple-domain amnestic MCI (mdMCI-a) and 132 with amnestic MCI (aMCI). Several clinical vascular risk factors and magnetic resonance imaging (MRI) brain lesions were evaluated. <i>Results:</i> snmMCI showed a higher frequency of ischaemic heart disease and of transient ischaemic attack (TIA)/stroke, a higher Hachinski ischaemic score and …
Vegetation Patterns in the Hyperbolic Klausmeier Model with Secondary Seed Dispersal
2023
This work focuses on the dynamics of vegetation stripes in sloped semi-arid environments in the presence of secondary seed dispersal and inertial effects. To this aim, a hyperbolic generalization of the Klausmeier model that encloses the advective downhill transport of plant biomass is taken into account. Analytical investigations were performed to deduce the wave and Turing instability loci at which oscillatory and stationary vegetation patterns arise, respectively. Additional information on the possibility of predicting a null-migrating behavior was extracted with suitable approximations of the dispersion relation. Numerical simulations were also carried out to corroborate theoretical pre…
Liikunnan vaikutus verensokerin hallintaan tyypin 1 diabeetikoilla
2015
Tyypin 1 diabetekselle olennaista on oman insuliinin erityksen puute, mikä johtaa verensokerin nousuun. Hoidon tavoitteena on taata mahdollisimman hyvä elämänlaatu ja estää lisäsairauksien synty, missä insuliinihoito on elinehto ja terveillä elämäntavoilla on olennainen rooli. Fyysisellä aktiivisuudella on joissakin tutkimuksissa todettu olevan positiivinen vaikutus glykohemoglobiini-arvoon (HbA1c), joka kuvaa verensokerin tasoa edeltävältä 2-3 kuukaudelta. Liikunta itsessään on merkittävä elimistön tasapainon järkyttäjä ja aiheuttaa muutoksia energia-aineenvaihdunnassa. Seurauksena voi olla hypo- tai hyperglykemia. Liikunnan kesto ja rasittavuus vaikuttavat verensokerivasteeseen. Taustalla…
Preventing reverse engineering of native and managed programs
2015
One of the important aspects of protecting software from attack, theft of algorithms, or illegal software use is eliminating the possibility of performing reverse engineering. One common method used to deal with these issues is code obfuscation. However, it is proven to be ineffective. Code encryption is a much more effective means of defying reverse engineering, but it requires managing a cryptographic key available to none but the permissible users. The thesis presents a system for managing cryptographic keys in a protected environment and supporting execution of encrypted code. The system has strong security guarantees. In particular, the cryptographic keys are never stored on the target…
Modulation of Hepatitis C Virus NS5A Hyperphosphorylation by Nonstructural Proteins NS3, NS4A, and NS4B
1999
NS5A of the hepatitis C virus (HCV) is a highly phosphorylated protein involved in resistance against interferon and required most likely for replication of the viral genome. Phosphorylation of this protein is mediated by a cellular kinase(s) generating multiple proteins with different electrophoretic mobilities. In the case of the genotype 1b isolate HCV-J, in addition to the basal phosphorylated NS5A (designated pp56), a hyperphosphorylated form (pp58) was found on coexpression of NS4A (T. Kaneko, Y. Tanji, S. Satoh, M. Hijikata, S. Asabe, K. Kimura, and K. Shimotohno, Biochem. Biophys. Res. Commun. 205:320‐326, 1994). Using a comparative analysis of two full-length genomes of genotype 1b…
