Identification of a novel Drosophila melanogaster gene, angel, a member of a nested gene cluster at locus 59F4,5.
1996
The identification of a novel Drosophila melanogaster gene, angel, is presented in this study. angel is located on the right arm of the second chromosome at locus 59F5, close to the nested genes l(2)tid, l(2)not, l(2)rot and l(2)dtl. We describe the genetic and molecular localization of angel and present its temporal expression in the wild-type. The deduced amino acid sequence of the ANG39 protein is characterized by a nuclear localization signal. Furthermore, the central part of the predicted ANG39 protein shows significant homology to the C-terminal portion of the yeast transcriptional effector CCR4.
Cloning, structure, cellular localization, and possible function of the tumor suppressor gene lethal(3)malignant blood neoplasm-1 of Drosophila melan…
1994
The tumor suppressor gene, lethal(3)malignant blood neoplasm-1+, of Drosophila melanogaster is required for the differentiation of the phagocytic blood-cell type, the plasmatocyte. In the homozygously mutated state it causes the malignant transformation of these blood cells. We present here the cloning, sequencing, structure, and expression of the l(3)mbn-1+ gene during development. The cloned gene was identified by germ-line transformation, generation of revertants, and the detection of the corresponding mRNA in blood cells and other tissues. Homologies of the G-S-rich C-terminus of the putative MBN83 protein to human cytokeratins K1, K10, and mouse loricrin were found. The structure and p…

[1,2,3]Triazolo[1,5-a]pyridines. A theoretical (DFT) study of the ring-chain isomerization
2008
The ring opening isomerization of [1,2,3]triazolo[1,5-a]pyridines to the corresponding 2-pyridyl derivatives has been studied by means of DFT calculations at the B3LYP/6-31+G(d,p) computational level. The effect of the substitution as well as those of protonation, deprotonation, and lithiation on different positions has been studied. The electronic characteristics of the optimized structures have been analyzed by means of the Atoms In Molecules (AIM), Electron Localization Function (ELF), Molecular Electrostatic Potential (MEP), and Natural Bond Orbital (NBO) methodologies. © 2008 Elsevier Ltd.

Radicalization in Correctional Systems: A Scoping Review of the Literature Evaluating the Effectiveness of Preventing and Countering Interventions
2023
Although several prevention and countering radicalization programs in correctional institutions have been carried out in Europe and worldwide, little is known about their effectiveness. Thus, the current scoping review aimed at reporting on the state of the art of the literature assessing and evaluating such actions, identifying knowledge gaps, and examining methods used to assess their successfulness and impact. A total of eight studies that met eligibility criteria were reviewed after performing a search on Scopus, Web of Science, and PsychInfo (Ebsco) databases: Two studies evaluated a reintegration initiative based in the Netherlands; four focused on an Australian disengagement program;…
GW170817: Implications for the Stochastic Gravitational-Wave Background from Compact Binary Coalescences
2018
The LIGO Scientific and Virgo Collaborations have announced the first detection of gravitational waves from the coalescence of two neutron stars. The merger rate of binary neutron stars estimated from this event suggests that distant, unresolvable binary neutron stars create a significant astrophysical stochastic gravitational-wave background. The binary neutron star background will add to the background from binary black holes, increasing the amplitude of the total astrophysical background relative to previous expectations. In the Advanced LIGO-Virgo frequency band most sensitive to stochastic backgrounds (near 25 Hz), we predict a total astrophysical background with amplitude $\Omega_{\rm…
Devianze sessuali
2021
La sessualità è una delle dimensioni umane che hanno ricevuto maggiori forme di controllo, regolamentazione e normalizzazione. In particolare, essa è divenuta argomento di studio tramite approcci essenzialisti riconducibili al concetto di scientia sexualis, che proponeva una sessualità monolitica, ancorata ai concetti di giusto e sbagliato, morale e immorale, normale e anormale. dipendentemente dalle culture e organizzazioni di riferimento. Ancora oggi, nonostante le riflessioni in chiave simbolico-interazionista offerta da autori quali Garfinkel, Goffman e Simon e Gagnon, la sessualità appare regolamentata dal discorso medico e legata a doppio nodo dalla dimensione morale. Anche le discipl…
Search for Subsolar-Mass Ultracompact Binaries in Advanced LIGO's First Observing Run
2018
We present the first Advanced LIGO and Advanced Virgo search for ultracompact binary systems with component masses between 0.2 $M_\odot$ - 1.0 $M_\odot$ using data taken between September 12, 2015 and January 19, 2016. We find no viable gravitational wave candidates. Our null result constrains the coalescence rate of monochromatic (delta function) distributions of non-spinning (0.2 $M_\odot$, 0.2 $M_\odot$) ultracompact binaries to be less than $1.0 \times 10^6 \text{Gpc}^{-3} \text{yr}^{-1}$ and the coalescence rate of a similar distribution of (1.0 $M_\odot$, 1.0 $M_\odot$) ultracompact binaries to be less than $1.9 \times 10^4 \text{Gpc}^{-3} \text{yr}^{-1}$ (at 90 percent confidence). N…
Electronic fluxes during diels-alder reactions involving 1,2-benzoquinones: mechanistic insights from the analysis of electron localization function …
2012
By means of the joint use of electron localization function (ELF) and Thom's catastrophe theory, a theoretical analysis of the energy profile for the hetero-Diels-Alder reaction of 4-methoxy-1,2-benzoquinone 1 and methoxyethylene 2 has been carried out. The 12 different structural stability domains obtained by the bonding evolution theory have been identified as well as the bifurcation catastrophes (fold and cusp) responsible for the changes in the topology of the system. This analysis permits finding a relationship between the ELF topology and the evolution of the bond breaking/forming processes and electron pair rearrangements through the reaction progress in terms of the different ways o…
Crystal behavior of potassium bromate under compression.
2015
We report on high-pressure angle-dispersive X-ray diffraction data up to 15 GPa andab initiototal-energy calculations up to 242 GPa for KBrO3. No phase transition was found below 15 Pa in contrast to previously reported data. Its experimental bulk modulus in the quasi-hydrostatic regime isB0= 18.8 (9) GPa with a bulk modulus pressure derivativeB′0= 8.2 (4). However, according to ourab initiocalculations, KBrO3significantly reduces its rhombohedral distortionviasmall cooperative movements of the atoms and the structure progressively approaches the cubic symmetry, where the KBr subarray would adopt a topology similar to that of the corresponding B2-type bromide. This rearrangement of atoms is…
