Multipulse Fermi Gamma-Ray Bursts. I. Evidence of the Transition from Fireball to Poynting-flux-dominated Outflow [PDF]

open access: yesAstrophysical Journal Supplement Series, 2018
The composition of a jet is still an unsolved problem in gamma-ray bursts (GRBs). Several previous studies have suggested that the prompt emission spectrum of GRBs is likely to consist of a few components that may arise from different jet compositions ...

Telomere‐to‐Telomere Genomes Reveal that Multiscale Evolution Shapes the Largest Metabolic Arsenal of Diaporthe Fungi

open access: yesAdvanced Science, EarlyView.
This study presents the first telomere‐to‐telomere genomes and population resources for Diaporthe pathogens, uncovering the largest known fungal repertoire of secondary metabolite gene clusters. Structural variations and horizontal gene transfer drive cluster diversification, while specific rapidly evolving clusters control virulence, offering novel ...

GRB 181110A: Constraining the Jet Structure, Circumburst Medium and the Initial Lorentz Factor

open access: yesUniverse, 2022
The afterglow data of gamma ray bursts (GRBs) can be used to constrain the physical properties of the fireball (e.g., the jet structure and opening angle) and the circumburst medium.

Afterglows from precursors in Gamma Ray Bursts. Application to the optical afterglow of GRB 091024 [PDF]

open access: yes, 2014
About 15% of Gamma Ray Bursts have precursors, i.e. emission episodes preceding the main event, whose spectral and temporal properties are similar to the main emission.

The Geography of Success: A Spatial Analysis of Export Intensity in the Italian Wine Industry

open access: yesAgribusiness, EarlyView.
ABSTRACT This paper investigates the paradox of how Italy's fragmented, SME‐dominated wine industry achieves global export success. Moving beyond purely firm‐centric explanations, we test whether export intensity is spatially dependent, clustering geographically in regional ecosystems.

Cultivating Circularity: Harnessing Industry 4.0 and Stakeholder Engagement for a Sustainable Agrifood Future in Brazil

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study analyzed Industry 4.0 (I4.0) technology applications in agribusiness and the role of strategic stakeholders, engagement methods, and other critical aspects data sharing, confidentiality, integrity, decision‐making, and sector‐specific requirements in promoting circularity.

Confronting fluctuations of conserved charges in central nuclear collisions at the LHC with predictions from Lattice QCD

open access: yesPhysics Letters B, 2015
We construct net baryon number and strangeness susceptibilities as well as correlations between electric charge, strangeness and baryon number from experimental data at midrapidity of the ALICE Collaboration at CERN.

PF191012 Myszyniec - highest Orionid meteor ever recorded [PDF]

open access: yes, 2013
On the night of Oct 18/19, 2012 at 00:23 UT a -14.7 mag Orionid fireball occurred over northeastern Poland. The precise orbit and atmospheric trajectory of the event is presented, based on the data collected by five video and one photographic Polish ...
