We present realistic expectations for the number and properties of neutron star binary mergers to be detected as multi-messenger sources during upcoming fourth observing run (O4) LIGO-Virgo-KAGRA gravitational wave (GW) detectors, with aim providing guidance optimization strategies. Our predictions are based on a population synthesis model which includes GW signal-to-noise ratio, kilonova (KN) optical near-infrared light curves, relativistic jet gamma-ray burst (GRB) prompt emission peak...
Although rectal cancer is predominantly a disease of older patients, current guidelines do not incorporate optimal treatment recommendations for the elderly and address only partially associated specific challenges encountered in this population. This results wide variation disparity delivering standard care to subset patients. As burden population continues increase, it crucial assess whether on strategies general can be adopted adults, with same beneficial oncological functional outcomes....
The existence of merging black hole-neutron star (BHNS) binaries has been ascertained through the observation their gravitational wave (GW) signals. However, to date, no definitive electromagnetic (EM) emission confidently associated with these mergers. Such an association could help unravel crucial information on systems, for example, BH spin distribution, equation state (EoS) neutron and rate heavy element production. We modeled multi-messenger (MM) from BHNS mergers detectable during...
We aim to constrain the stellar initial mass function (IMF) during epoch of reionization. To this purpose, we build up a semi-empirical model for reionization history Universe based on various ingredients: latest determination UV galaxy luminosity from JWST out redshift z≲12; data-inferred and simulation-driven assumptions redshift-dependent escape fraction ionizing photons primordial galaxies; simple yet flexible parameterization IMF ϕ(m⋆)∼m⋆ξe−m⋆,c/m⋆ in terms high-mass end slope ξ<0...
In rectal cancer, the depth of tumor infiltration and metastatic involvement lymph nodes are important prognostic factors. Endosonography rectum, combining advantages both endoscopy sonography, provides information not available from other imaging diagnostic techniques. From January 1989 to December 1997, 85 patients affected by carcinoma were submitted preoperative evaluation with endorectal ultrasonography. 75 cases results obtained endosonography compared histology resected specimens....
A relativistic jet has been produced in the single well-localised binary neutron star (BNS) merger detected to date gravitational waves (GWs), and local rates of BNS mergers short gamma-ray bursts are same order magnitude. This suggests that formation is not a rare outcome for mergers, we show this intuition can be turned into quantitative constraint: at least about $1/3$ GW-detected $1/5$ all should produce successful (90\% credible level). Whether launched depends on properties remnant...
Pair-instability supernovae (PISNe) have crucial implications for many astrophysical topics, including the search very massive stars, black hole mass spectrum, and galaxy chemical enrichment. To this end, we need to understand where PISNe are across cosmic time, what their favourable galactic environments. We present a new determination of PISN rate as function redshift, obtained by combining up-to-date stellar evolution tracks from PARSEC FRANEC codes, with an semi-empirical star formation...
Only few case reports of mucinous cystic pancreatic neoplasm containing an undifferentiated carcinoma with osteoclast-like giant cells have been described in the literature. In majority cases this unusual association tumors seems related to a favorable outcome. We present second indeterminate mucin-producting area cells. The specific features two histotypes and rapid course disease make our clinical remarkable. A 68 year old female came attention for macrocystic mass detected...
Abstract In recent years, increasing attention has been devoted to semi-empirical, data-driven models tackle some aspects of the complex and still largely debated topic galaxy formation evolution. We here present a new semi-empirical model whose marking feature is simplicity: it relies on solely two assumptions, one initial condition free parameters. Galaxies are connected evolving dark matter haloes through abundance matching between specific halo accretion rate (sHAR) star (sSFR)....
The stellar initial mass function (IMF) represents a fundamental quantity in astrophysics and cosmology describing the distribution of stars from low all way up to massive very stars. It is intimately linked wide variety topics, including binary evolution, galaxy chemical enrichment, cosmological reionization. Nonetheless, IMF still remains highly uncertain. In this work, we aim determine with novel approach based on observed rates transients origin. We parametrize simple but flexible Larson...
The diffusion of cross-sectional imaging has recently permitted the detection an increasing number incidentalomas localized in distal pancreas. Currently, there are no studies literature exploring laparoscopic approach as treatment for left-sided pancreatic incidentalomas.We report a series 20 body and tail pancreas treated with surgery over period 2010-2014. incidental masses our included great variety histotypes relevant proportion malignant lesions. In two cases, procedures were converted...

<ns4:p>Introduction: Improvements in living conditions and progress medical management have resulted better quality of life longer expectancy. Therefore, the number older people undergoing surgery is increasing. Frailty often described as a syndrome aged patients where there augmented vulnerability due to progressive loss functional reserves. Studies suggest that frailty predisposes elderly worsening outcome after surgery. Since emergency associated with higher mortality rates, it paramount...
