Computational annotation of genes differentially expressed along olive fruit development
2009
Abstract Background Olea europaea L. is a traditional tree crop of the Mediterranean basin with a worldwide economical high impact. Differently from other fruit tree species, little is known about the physiological and molecular basis of the olive fruit development and a few sequences of genes and gene products are available for olive in public databases. This study deals with the identification of large sets of differentially expressed genes in developing olive fruits and the subsequent computational annotation by means of different software. Results mRNA from fruits of the cv. Leccino sampled at three different stages [i.e., initial fruit set (stage 1), completed pit hardening (stage 2) a…
Chromatographic fingerprint, antioxidant activity, and colour characteristic of polish goldenrod (Solidago virgaurea L.) honey and flower
2018
In recent times, the nutraceutical and pharmaceutical interest in honey due to its well-known health properties has increased. Consumers need clear and precise information, so that they can make informed choices about their diet and the foods they buy. Therefore, gas chromatography–mass spectrometry (GC–MS) and high-performance liquid chromatography with a photodiode array detector (HPLC-PAD) was revealed a general characteristic fingerprint of polish monofloral goldenrod honey and flowers. In addition, high-performance thin-layer chromatography (HPTLC) has proven to be a useful tool for determining similarity patterns of common bands among honey from the same floral source and thus can be …
Context matters-consensus molecular subtypes of colorectal cancer as biomarkers for clinical trials
2019
Abstract The Colorectal Cancer Subtyping Consortium identified four gene expression consensus molecular subtypes, CMS1 (immune), CMS2 (canonical), CMS3 (metabolic), and CMS4 (mesenchymal), using multiple microarray or RNA-sequencing datasets of primary tumor samples mainly from early stage colon cancer patients. Consequently, rectal tumors and stage IV tumors (possibly reflective of more aggressive disease) were underrepresented, and no chemo- and/or radiotherapy pretreated samples or metastatic lesions were included. In view of their possible effect on gene expression and consequently subtype classification, sample source and treatments received by the patients before collection must be ca…
Background subtraction and peak search from threefold gamma event data
1990
Abstract A method for subtracting background from triple-coincidence γ events is presented. In our data set it was used to remove 40% of the noise without affecting photopeaks with intensity of >18 counts. An example of performance of Ward's clustering algorithm applied to three-dimensional photopeak searching is also presented. Several standard clustering algorithms were found to be applicable only to background-subtracted data.
Modulāras un testējamas arhitektūras veidošana tīmekļa lietotnēm
2015
Lietotnēs ar sarežģītu biznesa funkcionalitāti ir svarīgi domāt par testējamību un modularitāti arhitektūras līmenī. Darba mērķis ir aprakstīt principus, kā veidot šādu koda arhitektūru tīmekļa lietotnei, īpaši koncentrējoties uz testējamību. Darba galvenās tēmas ir atkarību injicēšana, starpnozaru problēmu centralizēta risināšana, Entity Framework izmantošana kopā ar eksistējošu datubāzi, biznesa loģikas pārvaldīšana, servera un klienta puses uzturamu vienībtestu un integrācijas testu veidošana. Lai realizētu pētījumu, autors eksistējošai uzņēmuma informācijas sistēmai veica arhitektūras uzlabošanu, kā rezultātā tā tika salīdzināta ar veco lietotni, secinot, ka ir uzlabojusies uzturamība, …

Repatriation of Debt in the Euro Crisis: Evidence for the Secondary Market Theory
2013
The Euro Crisis has marked a sharp inversion in the process of the European financial integration and, more specifically, a repatriation of countries' debt from foreign to domestic investors. Yet the drivers of the financial fragmentation remain unclear. This paper investigates the empirical patterns in light of competing theories of cross-border portfolio allocation. Three main empirical regularities stand out: i) the repatriation of debt occurred primarily in crisis countries; ii) the repatriation affected mainly public debt; iii) the public debt of crisis countries was reallocated to politically influential countries within the Euro Area. Standard theories of portfolio allocation and hom…
Public debt, money and consumer prices: a vector error correction model for Germany
2015
In the paper, the authors analyse the interaction between public debt and inflation including the mutual impulse response. The European sovereign debt crisis brought once again a focus onto the consequences of government debt in combination with an expansionary monetary policy for the development of consumer prices. Public deficits can lead to higher inflation rates if the money supply is expansionary. The high level of national debt, not only in the Euro-crisis countries, and the strong increase in the total assets of the European Central Bank, as a result of the unconventional monetary policy, have caused fears of inflating government debt. The transmission from public debt to inflation t…
Debt Sustainability and Fiscal Space in a Heterogeneous Monetary Union: Normal Times Vs the Zero Lower Bound
2020
In this paper we study fiscal policy effects and fiscal space for countries in a monetary union with different levels of public debt. We develop a dynamic stochastic general equilibrium (DSGE) model of a two-country monetary union, calibrated to match the characteristics of Spain and Germany, in which debt sustainability is endogenously determined a la Bi (2012) to shape the responses of the risk premium on public debt. Policy shocks change the market’s expectation about future primary surplus, producing a direct effect on the sovereign risk premium and macroeconomic responses of the economy. In normal times the costs of a government spending driven fiscal consolidation in the high-debt cou…
Feature selection for KNN classifier to improve accurate detection of subthalamic nucleus during deep brain stimulation surgery in Parkinson’s patien…
2017
The tremor and dystonia associated with Parkinson’s disease can be treated with deep brain stimulation (DBS) implanted into the subthalamic nucleus (STN). The accurate STN detection is a complex neurosurgeon task during a DBS surgery since a proper fixing of stimulating electrodes will impact on the patient’s future life. The brain electrical signals obtained with Micro Electrodes Register (MER) are acquired at different depths of the brain during DBS surgery to detect STN. In our previous work, we found good accuracy performance to improve the localization of STN using K-Nearest Neighbours (KNN) supervised learning algorithm. However, for real-time classification, it is essential to reduce…
