Computational Models That Matter During a Global Pandemic Outbreak
2020
The COVID-19 pandemic is causing a dramatic loss of lives worldwide, challenging the sustainability of our health care systems, threatening economic meltdown, and putting pressure on the mental health of individuals (due to social distancing and lock-down measures). The pandemic is also posing severe challenges to the scientific community, with scholars under pressure to respond to policymakers’ demands for advice despite the absence of adequate, trusted data. Understanding the pandemic requires fine-grained data representing specific local conditions and the social reactions of individuals. While experts have built simulation models to estimate disease trajectories that may be enough to gu…
Heavy-quark spin symmetry for charmed and strange baryon resonances
2013
We study charmed and strange odd-parity baryon resonances that are generated dynamically by a unitary baryon-meson coupled-channels model which incorporates heavy-quark spin symmetry. This is accomplished by extending the SU(3) Weinberg-Tomozawa chiral Lagrangian to SU(8) spin-flavor symmetry plus a suitable symmetry breaking. The model generates resonances with negative parity from the s-wave interaction of pseudoscalar and vector mesons with 1/2(+) and 3/2(+) baryons in all the isospin, spin, and strange sectors with one, two, and three charm units. Some of our results can be identified with experimental data from several facilities, such as the CLEO, Belle, or BaBar Collaborations, as we…
IMI – Oral biopharmaceutics tools project – Evaluation of bottom-up PBPK prediction success part 4: Prediction accuracy and software comparisons with…
2020
Oral drug absorption is a complex process depending on many factors, including the physicochemical properties of the drug, formulation characteristics and their interplay with gastrointestinal physiology and biology. Physiological-based pharmacokinetic (PBPK) models integrate all available information on gastro-intestinal system with drug and formulation data to predict oral drug absorption. The latter together with in vitro-in vivo extrapolation and other preclinical data on drug disposition can be used to predict plasma concentration-time profiles in silico. Despite recent successes of PBPK in many areas of drug development, an improvement in their utility for evaluating oral absorption i…
Czerwona lista porostów zagrożonych na Śląsku Opolskim i Górnym Śląsku [Red List of threatened lichens in Opole Silesia and Upper Silesia]
2014
The thirth regional list of threatened and allied fungi is presented. The list is a result of investigation studies in Opole Silesia and Upper Silesia in S Poland. The status of threat to the lichen and allied fungi species used has been determined according to the IUCN Red List Categories in version 3. l (2001). The data obtained were compared with historical ones. While assigning given lichen species to suitable categories of threat the geographic criterium of their occurrence ranges was accepted because most source data from the study area concerns the distribution and frequency of species. The Red List includes 536 taxa of lichens, lichenicolous and saprobic fungi, which constitute 72.9…
Climate Data Records of Vegetation Variables from Geostationary SEVIRI/MSG Data: Products, Algorithms and Applications
2019
The scientific community requires long-term data records with well-characterized uncertainty and suitable for modeling terrestrial ecosystems and energy cycles at regional and global scales. This paper presents the methodology currently developed in EUMETSAT within its Satellite Application Facility for Land Surface Analysis (LSA SAF) to generate biophysical variables from the Spinning Enhanced Visible and InfraRed Imager (SEVIRI) on board MSG 1-4 (Meteosat 8-11) geostationary satellites. Using this methodology, the LSA SAF generates and disseminates at a time a suite of vegetation products, such as the leaf area index (LAI), the fraction of the photosynthetically active radiation absorbed …
A Distributed approach to the Remote Control and Programming Improvement
2006
The remote control of industrial plants through networks is becoming very important nowadays but it involves several issues that can degrade the performance and usability of the remote plant. This paper presents a distributed architecture improving a remote programming system which allows users to control and to program a plant remotely. The control system is based on a client/server architecture with many user interfaces that control the plant. The remote programming language is a mix of Java and client/server protocol in order to simplify the developing and to avoid the protocol/language translation. In order to obtain more efficiency, the program is developed in the client side and it is…
On the 1-handles of the product V3XBn for a simply connected open 3-manifold V3
2013
Although \pi_1^\inftyV^3 is an obstruction for killing stably the 1-handles of an open simply connected 3-manifold V^3, one can always get rid of the 1-handles of V^3\times B^n, for high enough n, at price of a certain nonmetrizable slackening of the topology.
Role of the socioeconomic factors and regional policy in the demographic development of Latvia
2017
Promocijas darbā ir izpētīta reģionālā demogrāfiskā attīstība Latvijā ar mērķi noteikt savstarpējās sakarības starp reģionu demogrāfisko dinamiku, to ietekmējošajiem sociāli ekonomiskajiem faktoriem un reģionālās politikas pasākumiem. Darbā uzsvērta laika un telpas dimensija, kas ir ļoti svarīga, atklājot jaunas, iepriekš nekonstatētas reģionālas demogrāfiskās problēmas. Autors secina, ka personīgie ienākumi un nodarbinātība ir pozitīvās reģionālās demogrāfiskās attīstības svarīgākie priekšnosacījumi. Tiek pierādīts, ka ES fondu ieguldījumi spēj pozitīvi ietekmēt dažus demogrāfiskus procesus un to ietekmei ir raksturīgs telpiskās pārteces efekts. Vēsturiskās un telpiskās analīzes rezultāti …
Osseous oral hyaline ring granuloma mimicking a mandible tumor in a child with congenital agenesis of the corpus callosum
2017
Background Hyaline ring granuloma (HRG) of the oral cavity is an uncommon disorder considered to be a foreign-body reaction resulting from implantation of food vegetable particles. Microscopically, it is characterized by the presence of structures of hyaline rings in an inflamed fibrous tissue background, which contains multinucleated giant cells. Material and methods We present the case of a 4-year-old boy diagnosed with a mandible osseous HRG, which showed clinical and tomographic aspects suggestive of an aggressive bone tumor. Results The patient underwent surgical exploration and histopathologic analysis showed fragments composed predominantly of widespread dense connective tissue with …

2019
Background The aim of this study was to determine if the treatment with bisphosphonates other anti-resorptive and antiangiogenic agents influences the success of regenerative and / or implant treatments. Material and Methods We reviewed the literature from the last 5 years in the PubMed database, using the following words: “Sinus Floor Augmentation”[Mesh] OR “Dental Implants”[Mesh]) OR “Guided Tissue Regeneration”[Mesh]) AND “Osteonecrosis”[Mesh]. The articles were selected following the inclusion and exclusion criteria and were evaluated using the 22 items of the STROBE declaration. The following PICO clinical question was applied: Does the treatment with agents associated with drug osteon…
