Gaussian processes retrieval of crop traits in Google Earth Engine based on Sentinel-2 top-of-atmosphere data.

2022

The unprecedented availability of optical satellite data in cloud-based computing platforms, such as Google Earth Engine (GEE), opens new possibilities to develop crop trait retrieval models from the local to the planetary scale. Hybrid retrieval models are of interest to run in these platforms as they combine the advantages of physically-based radiative transfer models (RTM) with the flexibility of machine learning regression algorithms. Previous research with GEE primarily relied on processing bottom-of-atmosphere (BOA) reflectance data, which requires atmospheric correction. In the present study, we implemented hybrid models directly into GEE for processing Sentinel-2 (S2) Level-1C (L1C)…

Sex differences in correlates of intermediate phenotypes and prevalent cardiovascular disease in the general population

2015

Background: There are marked sex differences in cardiovascular disease (CVD) manifestation. It is largely unknown how the distribution of CVD risk factors or intermediate phenotypes explain sex-specific differences. Methods and Results: In 5000 individuals of the population-based Gutenberg Health Study, mean age 55 ± 11 years, 51% males, we examined sex-specific associations of classical CVD risk factors with intima-media thickness, ankle-brachial index, flow-mediated dilation, peripheral arterial tonometry, echocardiographic, and electrocardiographic variables. Intermediate cardiovascular phenotypes were related to prevalent CVD [coronary artery disease, heart failure, stroke, myocardial i…

Identification of a new nonsense mutation (Tyr129Stop) of the SRY gene in a newborn infant with XY sex-reversal.

2004

Point mutations and deletions of SRY gene have been described in several cases of XY gonadal dysgenesis. To date, most of these mutations affect the HMG domain of SRY which plays a central role in DNA binding activity of SRY. We report on a non-mosaic XY sex-reversed newborn girl (completely female external genitalia). The direct sequencing of SRY showed a new nonsense mutation in a codon of SRY gene flanking the 3' end of the HMG domain: a thymine is replaced by a guanine at position +387 in codon 129, resulting in the replacement of the amino acid tyrosine (TAT) by a stop codon (TAG). The new mutation of this patient provides further evidence to support the functional importance of the pu…

2016

Maģistra darba mērķis bija izpētīt dzimumlomu, piesaistes stila un uz rūpēm balstītās morāles saistības. Tika izvirzīti sekojoši jautājumi: kādas sakarības pastāv starp dzimumlomu, uz rūpēm balstīto morālo spriešanu un piesaistes stilu sievietēm un kā dzimumloma un piesaistes stils prognozē uz rūpēm balstīto morālo spriešanu? Pētījumā piedalījās 31 sieviete. Izmantotās metodikas: Attiecību aptauja (Relationship Questionaire, Bartholomew & Horowitz, 1991); Bēmas dzimumlomu aptauja (Bem Sex Role Inventory, Bem, 1974); Rūpju ētikas intervija (The ethics of care interview, Skoe, 1993). Tika atrasta statistiski nozīmīga saistība drošā piesaistes stila un uz rūpēm balstītā morālās spriešanas līme…

Inulin Derivatives Obtained Via Enhanced Microwave Synthesis for Nucleic Acid Based Drug Delivery

2015

A new class of therapeutic agents with a high potential for the treatment of different socially relevant human diseases is represented by Nucleic Acid Based Drugs (NABD), including small interfering RNAs (siRNA), decoy oligodeoxynucleotides (decoy ODN) and antisense oligonucleotides (ASOs). Although NABD can be engineered to be specifically directed against virtually any target, their susceptibility to nuclease degradation and the difficulty of delivery into target tissues severely limit their use in clinical practice and require the development of an appropriate nanostructured delivery system. For delivery of NABD, Inulin (Inu), a natural, water soluble and biocompatible polysaccharide, wa…

Zakorzenienie gospodarstw rolnych w lokalnych (regionalnych) systemach biobiznesu – uwarunkowania instytucjonalne w województwie opolskim

2016

Celem opracowania jest wskazanie na rolę instytucji w kreowaniu lokalnych (regionalnych) biobiznesów. Lokalne biobiznesy opierają się na unikatowym wykorzystaniu zarówno standardowych, jak i specyficznych zasobów terytoriów, w których są zakładane. Analizę przeprowadzono z wykorzystaniem trzech wymiarów transformacji europejskiego modelu rolnictwa: regulacji środowiskowych, dyfuzji wiedzy i informacji oraz powiązań międzyorganizacyjnych i społecznych. Na podstawie przeprowadzonych badań ankietowych zidentyfikowano stopień zakorzenienia instytucji zarządzających powstaniem biogospodarki w sieciach społecznych użytkowników towarowych gospodarstw rolnych w województwie opolskim. Praca ma chara…

Testing and implementing a new approach to estimating interregional output multipliers using input-output data for South Korean regions

2020

Flegg's location quotient (FLQ) is a useful tool for estimating intraregional output multipliers. This paper uses it as one component when estimating interregional multipliers. Using statistical information criteria and official data for 16 South Korean regions, it is found that the best approach is to combine the FLQ with a simple trade model. The paper explains how the proposed procedure can be implemented for both multiple and individual regions, and also how a region-specific value for the unknown parameter δ in the FLQ formula can be determined. Finally, an illustrative case study of one of the regions is carried out.

Uzdevumos balstīta prezentācijas prasmju pilnveide augstskolā

2017

Mūsdienās prezentēšanas prasmes ir kļuvušas par aktuālu tematu. Prasme prezentēt auditorijas priekšā augstskolās ietekmē ne tikai personīgo izaugsmi, bet arī karjeru nākotnē. Lai sniegtu pārliecinošu prezentāciju, prezentētājam būtu jāzin pārliecināšanas paņēmieni. Maģistra darba mērķis bija izpētīt prezentācijas prasmju pilnveidi augstkolās, koncentrējoties uz uzdevumiem, kas aptver konkrētus pārliecināšanas paņēmienus. Pētījuma rezultāti parāda, ka studenti apzinās konkrētu pārliecināšanas paņēmienu nozīmi, bet ir piesardzīgi to lietojumā sniedzot prezentāciju, kas var tikt pamatots ar zemu angļu valodas prasmi.
