Przyczynek do kwestii estetycznej około roku 1897
2017
A ąuestionnaire on “the essence and goal of a novel” published in 1897 in “Kurier Niedzielny” is an interesting documentation of aesthetic views of writers and literary critics in the late 19th century. Representatives of all literary generations of that time - from pre-positivists through two generations of Polish positivists to Young Poland writers - speak in favor of moderate aestheticism protesting against bias in literaturę and defend the autonomy of an artist. Quotes from participants exhibit good command of both idealistic (post-Hegel) aesthetic tradition and emotionalistic concepts of Positivism. They also foreshadow aesthetic predilection of Modemism. They do not provide an in-dept…
N-attiecības ietekme uz izdzīvotību pacientiem ar kuņģa vēzi pēc gastrektomijām ar paplašinātām limfadenektomijām
2021
Ievads: N-attiecība ir prognostisks rīks, kas spēj samazināt TNM stadijas uzliktās stadijas migrāciju. Atbilstoši N-attiecība spētu papildināt esošo TNM klasifikācijas sistēmu tādējādi būtu iespējams samazināt nepareizas stadijas uzlikšanu. Darba mērķis: Izpētīt limfmezglu attiecības ietekmi uz izdzīvotību pacientiem ar kuņģa vēzi pēc gastrektomijām ar paplašinātām limfadenektomijām. Darba uzdevumi: Iepazīties ar jaunāko literatūtu, ievākt pacientu datus no 2014 - 2015 gada, apkopot klīniski-patoloģiskos faktorus veikt šo faktoru analīzi un veikt secinājumus. Rezultāti: Pētījums rāda, ka N-attiecības un pN rādītāja 5 gadu izdzīvotība ir līdzvērtīga. Tika konstatēts, ka N-attiecība ir progno…
Vacancy-like Dressed States in Topological Waveguide QED
2020
We identify a class of dressed atom-photon states formingat the same energy of the atom at any coupling strength. As a hallmark, their photonic component is an eigenstate of the bare photonic bath with a vacancy in place of the atom. The picture accommodates waveguide-QED phenomena where atoms behave as perfect mirrors, connecting in particular dressed bound states (BS) in the continuum or BIC with geometrically-confined photonic modes. When applied to photonic lattices, the framework provides a general criterion to predict dressed BS in lattices with topological properties by putting them in one-to-one correspondence with photonic BS. New classes of dressed BS are thus predicted in the pho…
Work fluctuations in bosonic Josephson junctions
2016
We calculate the first two moments and full probability distribution of the work performed on a system of bosonic particles in a two-mode Bose-Hubbard Hamiltonian when the self-interaction term is varied instantaneously or with a finite-time ramp. In the instantaneous case, we show how the irreversible work scales differently depending on whether the system is driven to the Josephson or Fock regime of the bosonic Josephson junction. In the finite-time case, we use optimal control techniques to substantially decrease the irreversible work to negligible values. Our analysis can be implemented in present-day experiments with ultracold atoms and we show how to relate the work statistics to that…
Superconducting size effect in thin films under electric field: Mean-field self-consistent model
2019
We consider effects of an externally applied electrostatic field on superconductivity, self-consistently within a BCS mean field model, for a clean 3D metal thin film. The electrostatic change in superconducting condensation energy scales as $\mu^{-1}$ close to subband edges as a function of the Fermi energy $\mu$, and follows 3D scaling $\mu^{-2}$ away from them. We discuss nonlinearities beyond gate effect, and contrast results to recent experiments.
Association between clusters of diseases and polypharmacy in hospitalized elderly patients: results from the REPOSI study.
2011
BACKGROUND: Although the association between multimorbidity and polypharmacy has been clearly documented, no study has analyzed whether or not specific combinations of diseases influence the prescription of polypharmacy in older persons. We assessed which clusters of diseases are associated with polypharmacy in acute-care elderly in-patients. METHODS: This cross-sectional study was held in 38 Italian internal medicine and geriatric wards participating in the Registro Politerapie SIMI (REPOSI) study during 2008. The study sample included 1155 in-patients aged 65 years or older. Clusters of diseases, defined as two or more co-occurring specific chronic diseases, were identified using the odds…
Public spending decisions and the role of municipalities in local development in Argentina: An approach from the municipal autonomy and social and po…
2018
El desarrollo endógeno es un tema prioritario en la agenda municipal, atento el rol de liderazgo que les compete a los gobiernos locales en este proceso. A raíz de distintos procesos de descentralización operados desde el nivel central de gobierno hacia los subnacionales, los municipios se han visto obligados a diseñar estrategias y políticas públicas conjuntas con los distintos actores locales, individuos, organizaciones, políticos y asociaciones de la sociedad civil en general, en la búsqueda de soluciones a las problemáticas que plantea la sociedad hoy. En este trabajo se intentará analizar cómo se inserta el gobierno local, en tanto articulador de los esfuerzos de la comunidad, dentro d…
Optical properties of GaSe, characterization and simulation
2021
Abstract The study focuses on structural and optical characterizations and properties of the GaSe lamellar material in one hand and on a numerical simulation of the photovoltaic properties of the ITO/GaSe heterojunction in a second hand. A few layers of GaSe were exfoliated from bulk GaSe on PET substrate. The optical transmission was recorded at room temperature. It shows that GaSe exhibits both indirect and direct band gaps of about 1.92 and 2.2 eV respectively. A value, as high as 104 cm−1, of the absorption coefficient was obtained. The corresponding refractive index has been determined numerically according to the Sellmeier and Cauchy models. The interesting value of absorption shows o…
Coeval Cold Spray Additive Manufacturing Variances and Innovative Contributions
2017
Tremendous attention has been given to the cold spray process, even more today with the emergence of additive manufacturing, worldwide. Several inventions related to the cold spray technology have been patented for over a century and mostly since a couple of decades. But the cold spray technology knows a period of great innovations due to recent and current substantial explorations. Various technological solutions have been developed. The technical dimension, and particularly in terms of manufacturing method, has also always been a major genesis of progresses and novelties. This chapter is a technological survey of the cold spray additive manufacturing and reports variant methods and innova…
High-frequency electrodeless lamps in argon–mercury mixtures
2005
In this paper, numerical and experimental investigations of high-frequency (HF) electrodeless lamps in argon–mercury mixtures are performed. The intensities of the mercury spectral lines having wavelengths λ = 404.66, 435.83, 546.07 nm (7 3S1–6 3P0,1,2) and the resonance line λ = 253.7 nm (6 3 P1–6 1S0) are measured at a wide range of mercury pressures, varying the HF generator current and argon filling pressure. A stationary self-consistent model of HF electrodeless discharge lamp is developed including kinetics of the excited mercury and argon atomic states. Based on the developed model, the radiation characteristics of the discharge plasma are calculated. Numerical simulation of the line…
