Characterization of a digital camera as an absolute tristimulus colorimeter

2003

An algorithm is proposed for the spectral and colorimetric characterization of digital still cameras (DSC) which allows them to be used as tele-colorimeters with CIE-XYZ color output, in cd/m2. The spectral characterization consists in the calculation of the color-matching functions from the previously measured spectral sensitivities. The colorimetric characterization consists in trans- forming the raw RGB digital data into absolute tristimulus values CIE-XYZ (in cd/m2) under variable and unknown spectroradiometric conditions. Thus, in the first stage, a gray balance was applied over the raw RGB digital data to convert them into RGB relative colorimetric values. In the second stage, an algo…

Solvent Determines Nature of Effective Interactions between Nanoparticles in Polymer Brushes

2015

We study the effective interaction between two parallel rod-like nanoparticles in swollen and collapsed polymer brushes as a function of penetration depth by 2D self-consistent field calculations. In vertical direction, the interaction is always attractive. In lateral direction, the behavior under good and poor solvent conditions is qualitatively different. In swollen brushes (good solvent), nanoparticles always repel each other. In collapsed brushes (poor solvent), we identify two different regimes: an immersed regime, where the nanoparticles are fully surrounded by the brush, and an interfacial regime, where they are located in the interface between brush and solvent. In the immersed regi…

In order to investigate the influences of different end-groups on oligomer miscibility with other substances, oligo(propylene glycol)s bearing OH groups (OPG-OH) studied in the previous paper2, were acetylated at both ends (OPG-AC). The limits of miscibility of OPG-AC with oligo(dimethylsiloxane) (ODMS) were measured turbidimetrically. A simple and reliable method for the determination of the critical points from turbidity data is presented. The observed upper critical temperatures (Tc) increase with degree of oligomerization of ODMS (ranging from 1 to 5), whereas Tc shows a minimum when the degree of oligomerization of the OPG-AC is raised (from 1 to 57,5). For lower mol. wt. oligoglycols,…

Questions and controversies in the study of time-varying functional connectivity in resting fMRI.

2020

The brain is a complex, multiscale dynamical system composed of many interacting regions. Knowledge of the spatiotemporal organization of these interactions is critical for establishing a solid understanding of the brain’s functional architecture and the relationship between neural dynamics and cognition in health and disease. The possibility of studying these dynamics through careful analysis of neuroimaging data has catalyzed substantial interest in methods that estimate time-resolved fluctuations in functional connectivity (often referred to as “dynamic” or time-varying functional connectivity; TVFC). At the same time, debates have emerged regarding the application of TVFC analyses to re…

Correction: Daunorubicin reduces MBNL1 sequestration caused by CUG-repeat expansion and rescues cardiac dysfunctions in a Drosophila model of myotoni…

2018

ABSTRACT Myotonic dystrophy (DM) is a dominantly inherited neuromuscular disorder caused by expression of mutant myotonin-protein kinase (DMPK) transcripts containing expanded CUG repeats. Pathogenic DMPK RNA sequesters the muscleblind-like (MBNL) proteins, causing alterations in metabolism of various RNAs. Cardiac dysfunction represents the second most common cause of death in DM type 1 (DM1) patients. However, the contribution of MBNL sequestration in DM1 cardiac dysfunction is unclear. We overexpressed Muscleblind (Mbl), the Drosophila MBNL orthologue, in cardiomyocytes of DM1 model flies and observed a rescue of heart dysfunctions, which are characteristic of these model flies and resem…

Optometriskie treniņi pacientiem ar idiopātisku nistagmu.

2020

Maģistra darbs ir uzrakstīts angļu valoda uz 47 lapām. Tas satur 28 attēlus, 2 tabulas un 42 atsauces uz literatūras avotiem. Maģistra darba mērķis ir nodemonstrēt optometrisko rehabilitācijas metožu ietekmi uz infantilu idiopātisko nistagmu (IIN). Desmit pacientiem ar IIN (30 ± 14 g.) tika veiktas sekojošas ārstēšanas metodes: prizmas ar bāzi uz āru, krāsotas kontaktlēcas (zīlītes diametrs 5 mm), audio-biofīdbeka metode. Pirms un pēc ārstēšanas tika novērtēts redzes asums un kontrastredze tālumā un stereoredze tuvumā ar labāko subjektīvo korekciju, nistagma apmlitūda un frekvence. Rezultāti parādīja, ka visas ārstēšanas metodes vienādi ietekmēja redzes asuma, nistagma amplitūdas un frekven…

Redzes funkciju izvērtējums pacientiem agrīnā presbiopijas vecumā ar vienas dienas multifokālajām kontaktlēcām

2017

Bakalaura darbs uzrakstīts uz 27 lapaspusēm, satur 18 zīmējumus, 1 tabulu un 20 literatūras avotus. Darba mērķis ir novērtēt redzes asumu un kontrasta jūtību fotopiskos un mezopiskos apstākļos pacientiem, koriģētiem ar brillēm un vienas dienas multifokālajām kontaktlēcām. Mūsu pētījumi parādīja, ka fotopiskos apstākļos pacientiem pēc korekcijas ar multifokālajām kontaktlēcām redzes asums vidēji samazinājās par 0,02 logMAR vienībām. Mezopiskos krēslas apstākļos pacientiem koriģētiem ar multifokālajām kontaktlēcām redzes asuma samazinājums vidēji bija 0.05 logMAR vienības. Atšķirības redzes asumā ir statistiski nozīmīgas. Kontrasta jūtības vidējie lielumi pēc kontaktlēcu uzlikšanas vidēji sam…

Reversive constructions in Latin: the case of re- (and dis-)

2019

This paper proposes a cognitive account on re- and dis- verbs based on the scrutiny of the Plautine corpus and Cato’s De agricultura. Re- and dis- exhibit significant differences as to the manner in which they come to a reversive function, and these differences can be traced back to the basic conceptual import of the two prefixes: while dis- is schematically connected with the idea of separation into two parts, re- basically refers to a rearward/reditive trajectory, connecting a point that has already been reached to the starting point. On the basis of this description, I analyze the semantic network of re- and dis- and the role of their conceptual structure in the spread from spatial to re…
