Prasa polskiej emigracji politycznej w Wielkiej Brytanii wobec protestów robotników w kraju w czerwcu 1976 roku
2016
Strajki i demonstracje w Polsce, do których doszło 25 czerwca 1976 r. odbiły się żywym echem wśród emigracji w Wielkiej Brytanii. W artykule przedstawiono opinie i oceny emigracyjnych polityków oraz publicystów dotyczące przyczyn, przebiegu i konsekwencji czerwcowych protestów w kraju.
Anomalous transport effects on switching currents of graphene-based Josephson junctions
2017
We explore the effect of noise on the ballistic graphene-based small Josephson junctions in the framework of the resistively and capacitively shunted model. We use the non-sinusoidal current-phase relation specific for graphene layers partially covered by superconducting electrodes. The noise induced escapes from the metastable states, when the external bias current is ramped, give the switching current distribution, i.e. the probability distribution of the passages to finite voltage from the superconducting state as a function of the bias current, that is the information more promptly available in the experiments. We consider a noise source that is a mixture of two different types of proce…
Switching times in long-overlap Josephson junctions subject to thermal fluctuations and non-Gaussian noise sources
2014
We investigate the superconducting lifetime of long current-biased Josephson junctions, in the presence of Gaussian and non-Gaussian noise sources. In particular, we analyze the dynamics of a Josephson junction as a function of the noise signal intensity, for different values of the parameters of the system and external driving currents. We find that the mean lifetime of the superconductive state is characterized by nonmonotonic behavior as a function of noise intensity, driving frequency and junction length. We observe that these nonmonotonic behaviours are connected with the dynamics of the junction phase string during the switching towards the resistive state. An important role is played…
Low Levels of Acetylcholine Receptor Delta-Subunit Message and Protein in Human Thymus Suggests the Occurrence of ‘Triplet Receptors’ in Thymic Myoid…
2000
Myasthenia gravis (MG) is an autoimmune disease caused by autoantibodies against the acetylcholine receptor (AChR) at the neuromuscular junction [1]. The muscular AChR has been extensively characterized [2], but whether the muscular AChR plays a role during the initiation of MG is unknown [3]. The muscular AChR is a pentameric ion channel composed of 4 different subunits [2, 4]. The fetal AChR expressed during intrauterine life and after denervation of adult muscle exhibits an α2βδγ composition, while the adult AChR expressed after birth in innervated muscle exhibits an α2βδγ composition [4]. The α-subunit contains the main epitopes recognized by MG autoantibodies [2]. The human muscle AChR…
Evolution of a Non-Hermitian Quantum Single-Molecule Junction at Constant Temperature
2021
This work concerns the theoretical description of the quantum dynamics of molecular junctions with thermal fluctuations and probability losses. To this end, we propose a theory for describing non-Hermitian quantum systems embedded in constant-temperature environments. Along the lines discussed in [A. Sergi et al., Symmetry 10 518 (2018)], we adopt the operator-valued Wigner formulation of quantum mechanics (wherein the density matrix depends on the points of the Wigner phase space associated to the system) and derive a non-linear equation of motion. Moreover, we introduce a model for a non-Hermitian quantum single-molecule junction (nHQSMJ). In this model the leads are mapped to a tunneling…
K. G. Junga "Četrvienības teoloģija"
2016
Darbā „K. G. Junga „Četrvienības teoloģija”” aplūkoti K. G. Junga kristīgajai tematikai veltītie darbi, no kuriem secināma zināma Junga teoloģija, kura tiek „būvēta” ap fundamentālu pieņēmumu par kristīgās Trīsvienības nepilnīgumu, kas jāaizstāj ar Četrvienību. Darbā tiek apskatīti Junga reliģijas un reliģijas psiholoģijas teorijas pamatelementi, izsekojot judeo-kristīgā Dieva tēla attīstībai no rašanās jūdaisma vidē līdz nākotnes perspektīvai. Junga psihoteoloģija balstās pieņēmumā par Dieva arhetipa pakāpenisku manifestēšanos cilvēka psihē, radot arvien jaunu (vai papildinot jau esošo) Dieva tēlu. Šajā procesā ir trīs galvenās stadijas – bezapzināta vienotība, apzināta polarizācija un apz…
Optimization of impurity profile for p-n junction in heterostructures
2005
We analyze the dopant diffusion in p-n-junction in heterostructure, by solving the diffusion equation with space-varying diffusion coefficient. For a step-wise spatial distribution we find the optimum annealing time to decrease the p-n-junction thickness and to increase the homogeneity of impurity concentration in p or n regions.
Conjunction and Disjunction Among Conditional Events
2017
We generalize, in the setting of coherence, the notions of conjunction and disjunction of two conditional events to the case of n conditional events. Given a prevision assessment on the conjunction of two conditional events, we study the set of coherent extensions for the probabilities of the two conditional events. Then, we introduce by a progressive procedure the notions of conjunction and disjunction for n conditional events. Moreover, by defining the negation of conjunction and of disjunction, we show that De Morgan’s Laws still hold. We also show that the associative and commutative properties are satisfied. Finally, we examine in detail the conjunction for a family \(\mathcal F\) of t…
