Status of Advanced Virgo
2017
The LIGO and the Virgo collaborations have recently announced the first detections of Gravitational Waves. Due to their weak amplitude, Gravitational Waves are expected to produce a very small effect on free-falling masses, which undergo a displacement of the order of 10-18 m for a Km-scale mutual distance. This discovery showed that interferometric detectors are suitable to reveal such a feeble effect, and therefore represent a new tool for astronomy, astrophysics and cosmology in the understanding of the Universe. To better reconstruct the position of the Gravitational Wave source and increase the signal-to-noise ratio of the events by means of multiple coincidence, a network of detectors…
Coupled coincidence point results for (φ,ψ)-contractive mappings in partially ordered metric spaces
2014
Abstract. In this paper, we extend the coupled coincidence point theorems for a mixed g-monotone operator F : X × X → X $F:X\times X\rightarrow X$ obtained by Alotaibi and Alsulami [Fixed Point Theory Appl. (2011), article ID 44], by weakening the involved contractive condition. Two examples are given to illustrate the effectiveness of our generalizations. Our result also generalizes some recent results announced in the literature. Moreover, some applications to integral equations are presented.
Kriptovalūtas un to attīstība
2022
Bakalaura tēma: “Kriptovalūtas un to attīstība”. Tēmas aktualitāte ir saistīta ar kriptovalūtas modi kopš Bitcoin pirmās parādīšanās 2008. gadā. No šī brīža sāka attīstīties jauns potenciālais tirgus, kas mūsdienās ir ikdienas tēma ikvienam finanšu un monetārajā tirgos iesaistītajam. Kriptovalūtas parādījās kā dzīvotspējīga alternatīva tradicionālajām valūtām ar daudziem jauniem raksturojumiem, kā arī vairākiem aspektiem, kas dalās viedokļos starp tiem, kuri to saprot kā lielisku alternatīvu nākotnei, un skeptiskākiem, kuri joprojām apšauba tās likumību un izmantot. Mūsdienās kriptovalūta ir viena no interesantākajām tēmām finanšu tirgos visu ar to saistīto strīdu, kā arī sabiedrības akcept…
Bond Stretching and Redox Behavior in Coinage Metal Complexes of the Dichalcogenide Dianions [(SPh2P)2CEEC(PPh2S)2]2− (E=S, Se): Diradical Character …
2011
The metathetical reactions of a) [Li(tmeda)]2[(S)C(PPh2S)2] (Li2⋅3 c) with CuCl2 and b) [Li(tmeda)]2[(SPh2P)2CSSC(PPh2S)2] (Li2⋅4 c) with two equivalents of CuCl both afford the binuclear CuI complex {Cu2[(SPh2P)2CSSC(PPh2S)2]} (5 c). The elongated (C)S[BOND]S(C) bond (ca. 2.54 and 2.72 Å) of the dianionic ligand observed in the solid-state structure of 5 c indicate the presence of diradical character as supported by theoretical analyses. The treatment of [Li(tmeda)]2[(SPh2P)2CSeSeC(PPh2S)2] (Li2⋅4 b) and Li2⋅4 c with AgOSO2CF3 produce the analogous AgI derivatives, {Ag2[(SPh2P)2CEEC(PPh2S)2]} (6 b, E=Se; 6 c, E=S), respectively. The diselenide complex 6 b exhibits notably weaker Ag[BOND]Se…
Sezioni Unite -Scenari
2017
Si esaminano rispettivamente le decisioni con cui le Sezioni Unite hanno ritenuto l’ammissibilità del ricorso proposto da un avvocato iscritto nell’albo speciale della Corte di cassazione, nominato quale sostituto dal difensore dell’imputato di fiducia o di ufficio non cassazionista. Hanno poi escluso, anche nei riti camerali, l'obbligo del difensore di indicare l'impossibilità di presenziare all'udienza nei casi di malattia imprevedibile. Infine, hanno chiarito i poteri del giudice dell'impugnazione e del giudice dell'esecuzione nei casi in caso di sentenza di condanna, relativa a un reato successivamente abrogato e qualificato come illecito civile, sottoposto a sanzione pecuniaria civile,…
On the Substitutability between Paid-employment and Self-employment: Evidence from the Period 1969–2014 in the United States
2019
This paper provides estimates of the elasticity of substitution between operational and managerial jobs in the US economy during the years 1969–2014, derived from an aggregate CES production function. Estimating the long-term relationship between (the log of) the aggregate employment/self-employment ratio and (the log of) the returns from paid-employment relative to self-employment and testing for structural breaks, we report different estimates of the elasticity of substitution in each of the two regimes identified. To this end we apply the methodology on instability tests proposed in Kejriwal and Perron (2008, 2010) as well as the cointegration tests developed in Arai and Kurozumi (2007) …
A common virulence plasmid in biotype 2 Vibrio vulnificus and its dissemination aided by a conjugal plasmid.
2007
ABSTRACT Strains of Vibrio vulnificus , a marine bacterial species pathogenic for humans and eels, are divided into three biotypes, and those virulent for eels are classified as biotype 2. All biotype 2 strains possess one or more plasmids, which have been shown to harbor the biotype 2-specific DNA sequences. In this study we determined the DNA sequences of three biotype 2 plasmids: pR99 (68.4 kbp) in strain CECT4999 and pC4602-1 (56.6 kb) and pC4602-2 (66.9 kb) in strain CECT4602. Plasmid pC4602-2 showed 92% sequence identity with pR99. Curing of pR99 from strain CECT4999 resulted in loss of resistance to eel serum and virulence for eels but had no effect on the virulence for mice, an anim…

Implicaciones evolutivas de la transmisión colectiva de virus
2022
Es habitual asumir en virología que las partículas virales dispersan de forma libre e independiente durante su transmisión entre células, tejidos, órganos y hospedadores. Sin embargo, esta visión ha sido cuestionada recientemente por la caracterización de múltiples estrategias que los virus emplean para transmitirse colectivamente. Entre ellas se encuentran las llamadas unidades infecciosas colectivas, que incluyen agregados virales, viriones poliploides, vesículas extracelulares o estructuras específicas como los cuerpos de oclusión; pero también diversos modos de transmisión directa y masiva de viriones entre células. En principio, la agrupación de la progenie viral disminuye el número de…
Cueva de El Toro (Antequera, Malaga-Spain): a Neolithic stockbreeding community in the Andalusian region, between the 6th and 3th millennia BC
2004
The occupation evidence shown by the cave El Toro, is that of a unique stockbreeding community in the Andalusian region. The calibrated dates for this occupation period go from the second quarter of the sixth millennium up to the second millennium BP. There is also evidence of occasional occupation throughout later millennia up to the Hispano-Muslim period. The nature of thisoccupation is determined by the close link between the cave and the community which occupied it, both continuously and periodically. Throughout the occupation levels, the community's skillful control of technical processesand its remarkable knowledge on how to transform local primary resources, have shown that this comm…
