Postmodernisma īpašības un stāstījuma līdzekļi Kazuo Išiguro romānā un filmā "Dienas pārpalikums"

2022

Šis pētījums ir veltīts stāstījuma līdzekļu un postmoderno īpašību analīzei Kazuo Išiguro romānā “Dienas paliekas” un 1993. gada filmā, kas balstīta uz šo romānu. Šī darba mērķis ir noteikt postmodernisma īpašības un stāstījuma līdzekļus abos darbos un analizēt tās. Pētījums aptver īsu postmodernisma attīstības vēsturi literatūrā un kinematogrāfijā, kā arī stāstījuma teoriju un stāstījuma līdzekļus. Vēl viena bakalaura darba daļa ir veltīta stāstījuma līdzekļu un postmoderno īpašību analīzei un noteikšanai konkrētajā romānā un filmā, atbalstot pētījumu ar attiecīgiem citātiem. Tika secināts, ka abi darbi satur stāstījuma līdzekļus, piemēram, metaforas, simbolismu un ironiju, un postmodernis…

"Janie do Cię wracamy w czarnoleskie lipy". Polskie tradycje źródłowe w odmianach literacko-kulturowej współczesności (wybory - powtórzenia - różnice)

2018

The subject of the article - developed through the literary and cultural contexts of contemporary literature - concentrates mainly on different forms of the presence of tradition (targeting the Romantic one as key and the Old Polish as the subsequent one). A look at the styles and tones of the literature-"thriving" languages of these traditions allows us to see these traditions in a different critical light (national symbols/Polish signs/patters/transformations).

Timing an Accreting Millisecond Pulsar: Measuring the Accretion Torque in IGR J00291+5934

2006

We performed a timing analysis of the fastest accreting millisecond pulsar IGR J00291+5934 using RXTE data taken during the outburst of December 2004. We corrected the arrival times of all the events for the orbital (Doppler) effects and performed a timing analysis of the resulting phase delays. In this way we have the possibility to study, for the first time in this class of sources, the spin-up of a millisecond pulsar as a consequence of accretion torques during the X-ray outburst. The accretion torque gives us for the first time an independent estimate of the mass accretion rate onto the neutron star, which can be compared with the observed X-ray luminosity. We also report a revised valu…

Experimental on-demand recovery of entanglement by local operations within non-Markovian dynamics

2015

In many applications entanglement must be distributed through noisy communication channels that unavoidably degrade it. Entanglement cannot be generated by local operations and classical communication (LOCC), implying that once it has been distributed it is not possible to recreate it by LOCC. Recovery of entanglement by purely local control is however not forbidden in the presence of non-Markovian dynamics, and here we demonstrate in two all-optical experiments that such entanglement restoration can even be achieved on-demand. First, we implement an open-loop control scheme based on a purely local operation, without acquiring any information on the environment; then, we use a closed-loop s…

Quantum Non-Markovian Piecewise Dynamics from Collision Models

2017

Recently, a large class of quantum non-Markovian piecewise dynamics for an open quantum system obeying closed evolution equations has been introduced [B. Vacchini, Phys. Rev. Lett. 117, 230401 (2016)]. These dynamics have been defined in terms of a waiting-time distribution between quantum jumps, along with quantum maps describing the effect of jumps and the system's evolution between them. Here, we present a quantum collision model with memory, whose reduced dynamics in the continuous-time limit reproduces the above class of non-Markovian piecewise dynamics, thus providing an explicit microscopic realization.

CALIBRATION OF LÉVY PROCESSES USING OPTIMAL CONTROL OF KOLMOGOROV EQUATIONS WITH PERIODIC BOUNDARY CONDITIONS

2018

We present an optimal control approach to the problem of model calibration for L\'evy processes based on a non parametric estimation procedure. The calibration problem is of considerable interest in mathematical finance and beyond. Calibration of L\'evy processes is particularly challenging as the jump distribution is given by an arbitrary L\'evy measure, which form a infinite dimensional space. In this work, we follow an approach which is related to the maximum likelihood theory of sieves. The sampling of the L\'evy process is modelled as independent observations of the stochastic process at some terminal time $T$. We use a generic spline discretization of the L\'evy jump measure and selec…

On a nonlinear Schrödinger equation for nucleons in one space dimension

2021

We study a 1D nonlinear Schrödinger equation appearing in the description of a particle inside an atomic nucleus. For various nonlinearities, the ground states are discussed and given in explicit form. Their stability is studied numerically via the time evolution of perturbed ground states. In the time evolution of general localized initial data, they are shown to appear in the long time behaviour of certain cases.

"Mroczna otchłań". Archetypowa interpretacja opowiadania "Przemiana Juana Romero" Howarda P. Lovecrafta

2020

The setting of “The Transition of Juan Romero” – the short story by Howard Phillips Lovecraft, who was the originator of modern American horror fiction – is “the gold mine in the Cactus Range”. Drawing on the theories of Carl Gustav Jung, the author of the present interpretation amplifies the cultural dimensions of Lovecraft’s text, giving prominence to its origin from the ancient myths of the Aztecs, and using the so-called psychological alchemy to show the archetypal symbolism and structure of the story. Such a critical perspective, which takes into account different layers of the authorial intentionality and the reader’s response, reveals the complexity of the characters and situations, …
