Conceptual silencing as a rhetorical tool. A cognitive lexical semantics study of the lexical item Europe
2021
Taking a cognitive lexical semantics perspective, the article introduces the concept of conceptual silencing as a rhetorical tool. Understood as a process of conceptual dissolution of meaning to offer a more coarse-grained sense of an expression, conceptual silencing is demonstrated to have a potential rhetorical value in that it allows for more opaque reproduction of ideology. From a cognitive linguistic standpoint, the process of conceptual silencing hinges upon a polysemous nature of a lexical item and boils down to triggering a given sense of a given lexical item in a given context. To illustrate the workings of conceptual silencing, the article reports on a case study of the lexical it…
Transport of Antarctic stratospheric strongly dehydrated air into the troposphere observed during the HALO-ESMVal campaign 2012
2015
Abstract. Dehydration in the Antarctic winter stratosphere is a well-known phenomenon that is annually observed by satellites and occasionally observed by balloon-borne measurements. However, in situ measurements of dehydrated air masses in the Antarctic vortex are very rare. Here, we present detailed observations with the in situ and GLORIA remote sensing instrument payload aboard the German aircraft HALO. Strongly dehydrated air masses down to 1.6 ppmv of water vapor were observed as far north as 47° S in an altitude between 12 and 13 km in the lowermost stratosphere. The dehydration can be traced back to individual ice formation events above the Antarctic Peninsula and Plateau, where ice…
Predictive First-principles Modeling of a Photosynthetic Antenna Protein : The Fenna-Matthews-Olson Complex
2020
High efficiency of light harvesting in photosynthetic pigment-protein complexes is governed by evolutionary-perfected protein-assisted tuning of individual pigment properties and inter-pigment interactions. Due to the large number of spectrally overlapping pigments in a typical photosynthetic complex, experimental methods often fail to unambiguously identify individual chromophore properties. Here we report a first principles-based modeling protocol capable of predicting properties of pigments in protein environment to a high precision. The technique was applied to successfully uncover electronic properties of the Fenna-Matthews-Olson (FMO) pigment-protein complex. Each of the three subunit…

Toward Quaternary QCA : Novel Majority and XOR Fuzzy Gates
2022
As an emerging nanotechnology, quantum-dot cellular automata (QCA) has been considered an alternative to CMOS technology that suffers from problems such as leakage current. Moreover, QCA is suitable for multi-valued logic due to the simplicity of implementing fuzzy logic in a way much easier than CMOS technology. In this paper, a quaternary cell is proposed with two isolated layers because of requiring three particles to design this quaternary cell. Moreover, due to the instability of the basic gates, the three particles cannot be placed in one layer. The first layer of the proposed two-layer cell includes a ternary cell and the second one includes a binary cell. It is assumed that the over…
Populisms Latvijas politisko partiju diskursā laika periodā no 1993. līdz 2011. gadam
2015
Promocijas darba mērķis ir noskaidrot populisma līmeņa izmaiņas partiju priekšvēlēšanu programmās un noteikt tā saistību ar partiju rezultātiem likumdevēja vēlēšanās. Autore izvirza trīs hipotēzes: populisma līmenis politisko partiju priekšvēlēšanu programmās laika periodā no 1993. gada Saeimas vēlēšanām līdz 2011. gada Saeimas vēlēšanām ir palielinājies; to politisko partiju, kam ir iepriekšēja pieredze Saeimā, priekšvēlēšanu programmās ir konstatējams zemāks populisma līmenis, nekā to partiju priekšvēlēšanu programmās, kuras iepriekš Saeimā nav bijušas pārstāvētas; jo augstāks ir populisma līmenis attiecīgās partijas priekšvēlēšanu programmā, jo lielāku balsu skaitu tā iegūst vēlēšanās. D…
Mācību satura un valodas integrētas apguves pieejas izmantošana mācību priekšmetā "Politika un tiesībās" 12.klases skolēnu angļu valodas leksikas kom…
2022
Šajā diplomdarbā tika pētīta mācību satura un valodas integrētas mācīšanās (CLIL) ietekme uz 12.klases skolēnu angļu valodas leksikas kompetences attīstību mācību priekšmetā “Politika un tiesības”. Autore uzskata, ka CLIL ir jābūt jaunās Latvijas izglītības pieejas būtiskai sastāvdaļai, jo tā nodrošina integrētāku un jēgpilnāku mācīšanos. Gadījuma izpēte tika izvēlēta kā pētniecības metode, un izpētes grupu veidoja 25 12.klases skolēni. Dati, kas tika iegūti no anketām, pirms-testa, pēc-testa un intervijām ar CLIL skolotājiem, tika analizēti, lai novērtētu CLIL ietekmi un CLIL stundas. Skolēnu angļu valodas leksikas kompetence politikas jautājumos, jo īpaši tās receptīvā (uztveres) dimensij…
Od krytyki do czytelnictwa. Juliana Korhausera działalność krytycznoliteracka w pierwszej dekadzie XXI wieku
2015
The article is an attempt to recognize Julian Kornhauser’s critical idiom in the first decade of 21st century. The author takes steps to inscribe the critical project of The Inner World author into the congenial paradigm of the French thematic school (borders of empathy and identification, fascination and understanding, authenticity), and to pinpoint the basic ideas that Kornhauser’s critical thought circulates around (the issue of authenticity and identity of a poem persona and a critic).
Hyaluronan-coated polybenzofulvene brushes as biomimetic materials
2016
Hyaluronic acid (HA) forms pericellular coats in many cell types that are involved in the early stages of cell adhesion by interacting with the CD44 receptor. Based on the largely recognized overexpression of the CD44 receptor in tumor tissues, a polybenzofulvene molecular brush has been enveloped into hyaluronan shells to obtain a tri-component polymer brush (TCPB) composed of intrinsically fluorescent backbones bearing nona(ethylene glycol) arms terminated with low molecular weight HA macromolecules. The nanoaggregates obtained in TCPB water dispersions were characterized on the basis of dimensions, zeta potential, and in vitro cell toxicity. This biomimetic multifunctional material beari…
Embeddings of Danielewski hypersurfaces
2008
In this thesis, we study a class of hypersurfaces in $\mathbb{C}^3$, called \emph{Danielewski hypersurfaces}. This means hypersurfaces $X_{Q,n}$ defined by an equation of the form $x^ny=Q(x,z)$ with $n\in\mathbb{N}_{\geq1}$ and $\deg_z(Q(x,z))\geq2$. We give their complete classification, up to isomorphism, and up to equivalence via an automorphism of $\mathbb{C}^3$. In order to do that, we introduce the notion of standard form and show that every Danielewski hypersurface is isomorphic (by an algorithmic procedure) to a Danielewski hypersurface in standard form. This terminology is relevant since every isomorphism between two standard forms can be extended to an automorphism of the ambiant …
