The Stellar Initial Mass Function at the Epoch of Reionization [PDF]
, 2008 I provide estimates of the ultraviolet and visible light luminosity density at z~6 after accounting for the contribution from faint galaxies below the detection limit of deep Hubble and Spitzer surveys.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Patients with solid tumours or lymphomas have an increased risk of thromboembolism (TE) and thrombocytopenia. Evidence‐based strategies for anticoagulation therapy (ACT) for patients with thrombocytopenia are limited. We examined the impact of thrombocytopenia on ACT administration and bleeding incidence in children with solid ...

Isothermal Fragmentation: Is there a low-mass cut-off? [PDF]
, 2018 The evolution of self-gravitating clouds of isothermal gas forms the basis of many star formation theories. Therefore it is important to know under what conditions such a cloud will undergo homologous collapse into a single, massive object, or will ...

UniverseWe aim to constrain the stellar initial mass function (IMF) during the epoch of reionization. To this purpose, we build up a semi-empirical model for the reionization history of the Universe based on various ingredients: the latest determination of the ...

A Census of the Stellar Populations in the Sco-Cen Complex
The Astronomical Journal, 2021 I have used high-precision photometry and astrometry from the early installment of the third data release of Gaia (EDR3) to perform a survey for members of the stellar populations within the Sco-Cen complex, which consist of Upper Sco, UCL/LCC, the V1062

Pediatric Blood &Cancer, EarlyView.ABSTRACT Anaplastic sarcoma of the kidney (ASK) is a DICER1‐associated malignant tumor presumed to arise in a benign precursor, pediatric cystic nephroma (PCN). However, the initial oncogenic alteration(s) associated with malignant transformation are unknown.

The Origin of the Initial Mass Function [PDF]
, 2006 We review recent advances in our understanding of the origin of the initial mass function (IMF). We emphasize the use of numerical simulations to investigate how each physical process involved in star formation affects the resulting IMF.

Microlensing constraints on the Galactic bulge initial mass function [PDF]
Astronomy & Astrophysics, 2007 Aims. We seek to probe the Galactic bulge IMF starting from microlensing observations. Methods. We analyse the recent results of the microlensing campaigns carried out towards the Galactic bulge presented by the EROS, MACHO and OGLE collaborations. In particular, we study the duration distribution of the events.

Pediatric Blood &Cancer, EarlyView.ABSTRACT We present two pediatric cases of pediatric low‐grade gliomas (PLGG) with BRAF V600E mutations diagnosed and monitored using cerebrospinal fluid (CSF) liquid biopsy analyzed via digital droplet PCR (ddPCR), without tissue biopsy. Both patients were treated with dabrafenib and trametinib and monitored through clinical assessments, magnetic ...
