AnABlast: Re-searching for Protein-Coding Sequences in Genomic Regions
2019
AnABlast is a computational tool that highlights protein-coding regions within intergenic and intronic DNA sequences which escape detection by standard gene prediction algorithms. DNA sequences with small protein-coding genes or exons, complex intron-containing genes, or degenerated DNA fragments are efficiently targeted by AnABlast. Furthermore, this algorithm is particularly useful in detecting protein-coding sequences with nonsignificant homologs to sequences in databases. AnABlast can be executed online at http://www.bioinfocabd.upo.es/anablast/ .
A simple joint estimation-detection technique for OFDM systems
2005
In this work a simple approach for the joint estimation-detection in a frequency selective severe fading environment of OFDM signals adopting PSK constellations is presented. A linear predictor of suitable order is adopted for the channel estimation in the frequency domain. The predictor coefficients are estimated on the basis of a sample estimation of the autocorrelation of the channel frequency response, aided by a preliminary differential decoding, in a blockwise manner. The detection technique proposed here is based on a simple tree search where a small number of best survivor paths are maintained at each step. Despite the simplicity of above detection approach, the simulation results s…
La revisione del palinsesto veronese delle Istituzioni di Gaio e le schede di Bluhme
2014
In the light of unpublished material this paper reconstructs the history of the deciphering of Gaius’ palimpsest of the Capitular Library of Verona (BCapVr, Cod. XV) by Friedrich Bluhme. It deals for the first time with other copies of Bluhme’s transcriptions preserved at the Bonn University Library (ULB, S 675f; ULB, S 1440) and with their relationship to the ones at the Berlin State Library – Prussian Cultural Heritage (SBB-PK, Ms. lat. fol. 308, K. 2, Beil. 2, Fasz. 1).
Polarity factor 'Frizzled' in the demosponge Suberites domuncula: identification, expression and localization of the receptor in the epithelium/pinac…
2003
Until recently, it was assumed that polarity and axis formation have evolved only in metazoan phyla higher than Cnidaria. One key molecule involved in the signal transduction causing tissue polarity is Frizzled, a seven-transmembrane receptor that is activated by the Wnt family of secreted proteins. We report the isolation and characterization of a Frizzled gene from the demosponge Suberites domuncula (Sd-Fz). The deduced polypeptide comprises all characteristic domains known from Frizzled receptors of higher metazoans. In situ hybridization studies show that Sd-Fz is expressed in cells close to the surface of the sponges and in the pinacocytes of some canals. Northern blot analysis demonst…
FUNCTIONAL NONRETENTIVE FECAL SOILING AND STRESSFUL LIFE EVENTS
2019
Introduction: Functional non-retentive fecal soiling (FNRFS), or encopresis without constipation, is a common problem in pediatric age. FNRFS is associated with high levels of distress for both children and parents and with emotional disorders in about 30%-50% of affected children. This study aimed to evaluate stressors on a sample of children with FNRFS comparing to a group of typical devolpment children (TDC). Methods:154 subjects participated in the study: 56 FNRFS children (37 males; mean age 10.87 years ± 1.68); 98 TDC (65 males; mean age 11.3 years ± 1.85). All participants were evaluated for the presence of stressful events (LCU) using the Coddington Life Events Scales (CLES). Result…
Episodic memories: how do the hippocampus and the entorhinal ring attractors cooperate to create them?
2020
AbstractThe brain is capable of registering a constellation of events, encountered only once, as an episodic memory that can last for a lifetime. As evidenced by the clinical case of the patient HM, memories preserving their episodic nature still depend on the hippocampal formation, several years after being created, while semantic memories are thought to reside in neocortical areas. The neurobiological substrate of one-time learning and life-long storing in the brain, that must exist at the cellular and circuit level, is still undiscovered. The breakthrough is delayed by the fact that studies jointly investigating the rodent hippocampus and entorhinal cortex are mostly targeted at understa…
Albanese Maps and Fundamental Groups of Varieties With Many Rational Points Over Function Fields
2020
We investigate properties of the Albanese map and the fundamental group of a complex projective variety with many rational points over some function field, and prove that every linear quotient of the fundamental group of such a variety is virtually abelian, as well as that its Albanese map is surjective, has connected fibres, and has no multiple fibres in codimension one.
First morphological and molecular investigation of the mycobiota associated with Astragalus nebrodensis in its natural environment (Madonie mountains…
2023
Although Astragalus nebrodensis plays a fundamental ecological role, mycorrhizal fungi associated with this species have never been investigated in natural habitats. Our aim was to check the presence and occurrence of Arbuscular Mycorrhizal Fungi (AMF) in roots of A. nebrodensis in a natural habitat and to screen the fungal diversity in the surrounding soil, considering the positive influence of mycotrophic shrub species on soil microbiota. A morphological analysis was performed on A. nebrodensis roots samples from the Madonie mountains (Sicily, Italy), while high-throughput-sequencing was carried out in A. nebrodensis roots and in the associated soil. Observations of A. nebrodensis roots r…
Trace element variability in single ostracod valves as a proxy for hydrochemical change in Nam Co, central Tibet, during the Holocene
2014
Ostracod shells, belonging to three taxa (Leucocytherella sinensis Huang, 1982, ?Leucocythere dorsotuberosa Huang, 1982 and ?L. dorsotuberosa f. postilirata sensu Pang, 1985), were collected from two sediment cores from Lake Nam Co, on the central Tibetan Plateau. Two variants of LA–ICP–MS (laser ablation–inductively coupled plasma–mass spectrometry), spot and line-scan analyses, were used to investigate trace element concentrations (Mg, Sr, Ba, U and rare earth elements [REEs]) in single ostracod shells. The results suggest that the line-scan method can provide better precision than the spot analysis and is therefore preferred. No significant difference in trace element composition between…
Advances in spatial economic data analysis: methods and applications
2021
Spatial economic studies traditionally exploit areal data at the regional or sub-regional level. More recently, scholars have started to exploit spatial data of a different nature and, at the same time, extend the fields of application in economics. Specifically, this special issue contributes to the spatial economic literature by providing empirical evidence on a wide range of phenomena (socio-economic deprivation, land price volatility, electoral competition, real estate market, firm survival and tourism economics) and exploiting data at the municipality, firm, house and even individual level. At the same time, it tackles some of the methodological issues faced by the above-mentioned anal…
