Social Influence Maximization in Hypergraphs
2021
This work deals with a generalization of the minimum Target Set Selection (TSS) problem, a key algorithmic question in information diffusion research due to its potential commercial value. Firstly proposed by Kempe et al., the TSS problem is based on a linear threshold diffusion model defined on an input graph with node thresholds, quantifying the hardness to influence each node. The goal is to find the smaller set of items that can influence the whole network according to the diffusion model defined. This study generalizes the TSS problem on networks characterized by many-to-many relationships modeled via hypergraphs. Specifically, we introduce a linear threshold diffusion process on such …
Progressive symmetric erythro-keratosis associated with oligodontia, severe caries, disturbed hair growth and ectopic nail: a new syndrome?
2008
A 7-year-old girl had well-demarcated erythematous plaques covered with white pityriasiform scales which were symmetrically distributed and involved the extensor surfaces of the extremities as well as the abdomen, buttocks and face. Histological examination showed marked hyperkeratosis with parakeratosis, and a thickened granular cell layer, mild acanthosis and slight lymphocytic infiltration surrounding the papillary blood vessels, compatible with a diagnosis of progressive symmetrical erythrokeratodermia. Remarkably, a keratotic excrescence similar to a normal nail plate involved the tip of the nose since the age of 6 months. Moreover, occipital hairlessness, oligodontia and severe caries…
Effect of Cell Line and Differentiation on the Oxygenation Status of Experimental Sarcomas
1997
Since the measurement of tumor oxygenation status and the fraction of hypoxia within tumor tissue by computerized pO2-histography [10] has become increasingly im-portant in the clinical setting, many studies on tumor oxygenation in different experimental malignancies as well as in various human tumors have been carried out. Because pO2-histography is an invasive technique, this method has been used in humans mostly in superficial primary tumors and lymph node metastases [1,3,10] (for a review see [9]). Experimental studies in animals have been carried out on a wide range of isotransplanted rodent sarcomas or carcinomas [2,4,6–8,11] and of xenotransplanted human tumors [6]. The results obtai…
La vocalidad del violín en el norte de Italia en torno a 1600
2021
Throughout the present research I intend to demonstrate the powerful link between the vocal practice in accompanied monody and the way Early Italian violin music ought to be interpreted. Due to the scarce amount of articulation and ornamentation in this music, I consider that historical criteria should be found in order to back up the subjective choices in its performance. According to this, I focus on reviewing sources that describe the vocal practice around 1600, but also contemporary sources in which we can find instructions addressed to bow instruments. Besides, a catalogue of articulations and ornamentations present in early editions of printed violin music is attached. Last, I comment…
Introduction of a novel pathway for IAA biosynthesis to rhizobia alters vech root nodule developmt
2008
We introduced into Rhizobium leguminosarum bv. viciae LPR1105 a new pathway for the biosynthesis of the auxin, indole-3-acetic acid (IAA), under the control of a stationary phase-activated promoter active both in free-liv- ing bacteria and bacteroids. The newly introduced genes are the iaaM gene from Pseudomonas savastanoi and the tms2 gene from Agrobacterium tumefaciens. Free-living bacteria harbouring the promoter-iaaMtms2 construct release into the growth medium 14-fold more IAA than the wild-type parental strain. This IAA overproducing R. l. viciae, the RD20 strain, elicits the development of vetch root nodules containing up to 60-fold more IAA than nodules infected by the wild-type str…
Comparison between Laparoscopic and Robotic Approach for Sentinel Lymph Node Biopsy in Endometrial Carcinoma Women
2022
Robotic surgery has been approved as an alternative to laparoscopy to improve surgical outcomes. There is neither a consensus nor a systematic assessment of the literature about the superiority of the robotic approach over the laparoscopic one for sentinel lymph node (SLN) biopsy in endometrial carcinoma (EC) women. Therefore, a systematic review and meta-analysis was performed to compare the laparoscopic and robotic approaches for SLN biopsy in EC patients. Five electronic databases were queried from their inception to May 2022 for peer-reviewed studies, comparing such approaches in SLN biopsy in EC patients. The rate of detected SLN, dissected SLN, intraoperative and postoperative complic…
A gated material as immunosensor for in-tissue detection of IDH1-R132H mutation in gliomas
2021
[EN] A nanodevice consisted on nanoporous anodic alumina (NAA) supports functionalized with specific and selective antibody-based gatekeepers for the detection of IDH1-R132H mutant enzyme is here reported. Molecular profile and tissue mutations of the tumours (such as IDH1/IDH2 mutations in gliomas) are a great source of information that already make a difference in terms of prognosis and prediction of response to combined therapy. However, standardized methodologies to determine this mutation are time-consuming and cannot provide information before or during surgical intervention, which significantly limits their utility in terms of intraoperative decisionmaking. To solve this limitation, …
Tiešo nodokļu ieņēmumi valsts budžetā
2016
Nodokļu sistēmai ir veltīta būtiskāka loma valsts ekonomikā, jo tieši no nodokļu ieņēmu-miem veidojas valsts budžets. Nodokļu ieņēmumu apmērs valsts budžetā ir atkarīgs no iz-vēlētas nodokļu politikas. Bakalaura darbā tiek apskatīti ieņēmumi no tiešiem nodokļiem Eiropas Savienībā: Baltijas valsti un citi trīs ES dalībvalsti, kas no ekonomiska viedokļa ir labāk attīstīti. Galvenā problēma ir izvēlēties tādu nodokļu politiku, kas varētu padarīt lab-klājigāku ekonomisko situāciju valstī. Pētījuma galvenie rezultāti parāda kādā mērā atšķiras divu grupu nodokļa ieņēmumu līme-nis valsts budžetos un cik būtiski tas ir atkarīgs no izvēlētas valsts nodokļu politikas. Visās analizētās valstīs ir ES d…
Darba samaksas un darbaspēka nodokļu salīdzinošā analīze Baltijas Valstīs
2019
Maģistra darba temats ir “Darba samaksas un darbaspēka nodokļu salīdzinošā analīze Baltijas valstīs”. Darba mērķis ir darba samaksas un darbaspēka nodokļu salīdzinošo analīzi Baltijas valstīs, konstatēt atšķirības un izstrādāt priekšlikumus Latvijas darbaspēka nodokļu sistēmas uzlabošanai. 2018. gadā Latvijā tika veikta viena no būtiskākajām nodokļu reformām pēdējos gados, kura skārusi tieši darbaspēka nodokļus. Arī Lietuvā 2019. gadā tika veikta nozīmīga nodokļu reforma, kuras rezultātā sociālo iemaksu nodokļu slogs no darba devēja tika pārlikts uz darba ņēmēju. Turpretī Igaunijā kopš 2015. gada būtiskas izmaiņas attiecībā uz darbaspēka nodokļiem nav notikušas. Maģistra darba ietvaros auto…
Iedzīvotāju ienākuma nodokļu un valsts sociālā apdrošināšanas obligāto iemaksu piemērošana Latvijā
2018
Šī maģistra darba mērķis ir analizēt iedzīvotāju ienākuma nodokļu un valsts sociālā apdrošināšanas obligāto iemaksu piemērošanu Latvijā un to ietekmi uz valsts budžetu, kā arī sniegt priekšlikumus Latvijas nodokļu sistēmas uzlabošanai. Darba autore izvēlējas šo tēmu, jo uzskata, ka nodokļu politika ir ļoti aktuāls jautājums mūsdienās, kā arī tas ir būtisks instruments, lai palīdzētu valstij attīstīties. Darbā tiek analizēti darbaspēka nodokļi: IIN un VSAOI, kā arī, balstoties uz esošā gada izmaiņām, tiek aprēķināta darba samaksa pirms un pēc nodokļu reformas 2018. Darbā tiek apskatīti dažādi jautājumi saistībā ar šiem nodokļiem: gan nodokļu reforma, gan darbasspēka nodokļu ietekme uz valsts…
