Remnants of Anderson localization in prethermalization induced by white noise
2017
We study the non-equilibrium evolution of a one-dimensional quantum Ising chain with spatially disordered, time-dependent, transverse fields characterised by white noise correlation dynamics. We establish pre-thermalization in this model, showing that the quench dynamics of the on-site transverse magnetisation first approaches a metastable state unaffected by noise fluctuations, and then relaxes exponentially fast towards an infinite temperature state as a result of the noise. We also consider energy transport in the model, starting from an inhomogeneous state with two domain walls which separate regions characterised by spins with opposite transverse magnetization. We observe at intermedia…

Biomarkers in Anderson–Fabry Disease
2020
Fabry disease is a rare lysosomal storage disorder caused by a deficiency of α-galactosidase A, resulting in multisystemic involvement. Lyso-Gb3 (globotriaosylsphingosine), the deacylated form of Gb3, is currently measured in plasma as a biomarker of classic Fabry disease. Intensive research of biomarkers has been conducted over the years, in order to detect novel markers that may potentially be used in clinical practice as a screening tool, in the context of the diagnostic process and as an indicator of response to treatment. An interesting field of application of such biomarkers is the management of female heterozygotes who present difficulty in predictable clinical progression. This revi…
207 Diagnosis of Anderson-Fabry Disease in Childhood. What Should We Focus on?
2004
Background: Anderson-Fabry disease (FD) is an X-linked lysosomal storage disorder which also affects female carriers and has an early onset of symptoms in childhood in both genders. Signs and symptoms are frequently misunderstood and often diagnosis is made approximately 10–20 years after their onset. This has been clearly demonstrated by Fabry outcome survey (FOS) a European database on the natural history of FD and the effects of enzyme replacement therapy with agalsidase alfa (Replagal). Methods: Demographic data on 82 children (40 boys and 42 girls) below 18 years of age, with a median age at FOS entry of 12.9 (0.7–17.9) were analysed Results: Most frequently reported symptoms (60–80%) …
Cardiac manifestations of Anderson-Fabry disease in heterozygous females.
2002
AbstractObjectivesWe sought to define the prevalence of cardiac involvement in female patients with Anderson–Fabry disease (AFD).BackgroundAnderson–Fabry disease is a rare inborn X-linked lysosomal storage disorder. Globotriaosylceramide (Gb3), the major substrate of the deficient α-galactosidase A enzyme, accumulates progressively in vulnerable cells, including the cardiovascular system. It has been believed that heterozygous females have less cardiac involvement than hemizygous males with AFD.MethodsWe performed two-dimensional echocardiographic examinations of female patients heterozygous for AFD.ResultsSince 1997, a total of 55 female patients (mean age, 39.6 years; range, 6.1 to 70.8 y…
The Electronic Structure of Hexagonal BaCoO3
1999
Abstract TB–LMTO–ASA band structure calculations within the local spin density approximation have been performed to explain the magnetic and transport properties of BaCoO3. The calculations predict a magnetic and metallic ground state as energetically favored. BaCoO3 shows no long-range magnetic ordering, however, and only poor conductivity. The magnetic energy is low and the compound shows glassy susceptibility behavior at low temperatures. From the band structure we find Mott–Hubbard localization to be unlikely, and instead propose Anderson localization as a possible origin of the observed behavior. Calculations on slightly distorted structures exclude the possibility of a Peierls distort…
Polar bosons in one-dimensional disordered optical lattices
2013
We analyze the effects of disorder and quasi-disorder on the ground-state properties of ultra-cold polar bosons in optical lattices. We show that the interplay between disorder and inter-site interactions leads to rich phase diagrams. A uniform disorder leads to a Haldane-insulator phase with finite parity order, whereas the density-wave phase becomes a Bose-glass at very weak disorder. For quasi-disorder, the Haldane insulator connects with a gapped generalized incommesurate density wave without an intermediate critical region.
Moraalisten ja esteettisten arvostelmien suhde taiteessa : katsaus kohtuullisiin teorioihin
2015
Tämä tutkielma käsittelee moraalisten ja esteettisten arvostelmien suhdetta taiteessa keskittyen kolmeen kohtuulliseksi teoriaksi katsottuun näkemykseen: Noël Carrollin kohtuulliseen moralismiin, Berys Gautin etikismiin sekä Andersonin ja Deanin kohtuulliseen autonomismiin. Tarkoitukseni on selvittää, millä tavalla kukin näistä teoreetikoista näkee taiteen moraalin ja estetiikan suhteen. Tutkimuskysymyksessäni haluan ottaa selvää, onko taiteessa sekä moraalisia että esteettisiä arvostelmia ja vaikuttavatko nämä toisiinsa. Ennen siirtymistä varsinaisiin kohtuullisiin teorioihin pohjustan aihetta selvittämällä, kuinka taiteen moraaliin ja estetiikkaan on suhtauduttu historian kuluessa ja mite…
Solubility and stability of liebigite, Ca2UO2(CO3)3·10H2O(cr), in dilute to concentrated NaCl and NaClO4 solutions at T = 22–80 °C
2019
Abstract The solubility and thermodynamic stability of a synthetic liebigite was investigated in NaCl and NaClO4 solutions within a wide range of ionic strength (0.03 m ≤ Im ≤ 5.61 m), pH (7 ≤ pHm ≤ 9, with pHm = –log [H+]) and temperature (22 °C ≤ T ≤ 80 °C) conditions. A comprehensive characterization of the synthetic solid phase using XRD, quantitative chemical analysis, TG–DTA, SEM–EDS, IR and Raman spectroscopy confirmed the stoichiometry of Ca2UO2(CO3)3·10H2O(cr). At room temperature, liebigite remains stable and controls the solubility of U(VI) in the investigated NaCl and NaClO4 systems with Im ≤ 0.51 m. For the same temperature but high ionic strength (5.61 m NaCl), liebigite trans…
Painting the Unites States' Civil war: Or Creating a Brotherly War
2015
This article seeks to illustrate Benedict Anderson’s theory of the “Reassurance of Fratricide” and “the act of remembering/forgetting” through depictions of the Civil War in US fine arts. This is mostly done through the Smithsonian art data base and the paintings referenced under the label Civil War, spanning from the 1860s to the 1890s. This paper first analyzes how these paintings were used to depict the Confederate soldier’s otherness as typically American and thus helped with the post-war reintegration of the Confederacy. This study then examines how in certain paintings the war was brought inside the realm of domesticity and family, which reinforced the idea of a fratricide and a famil…
