Determinants of Compliance to Enhanced Recovery Protocol After Emergency Laparotomy

open access: yesWorld Journal of Surgery, EarlyView.
Enhanced Recovery protocols (ERP) are comprehensive, evidence‐based approaches aimed at accelerating patient recovery and improving surgical results; increasing evidence exists about their adoption in emergency laparotomy. The study aimed to evaluate the compliance to the proposed postoperative pathway and the determinants of late recovery.

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

open access: yesIntegrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

Origin and Evolution of Saturn's Ring System

open access: yes, 2009
The origin and long-term evolution of Saturn's rings is still an unsolved problem in modern planetary science. In this chapter we review the current state of our knowledge on this long-standing question for the main rings (A, Cassini Division, B, C), the

A Grammatical Interpretation of Horadam Sequences

open access: yesAxioms
The Horadam sequence {Hn(a,b;p,q)}n⩾0 has been widely studied in combinatorics and number theory. In this paper, we find that the context-free grammar G={x→px+y,y→qx} can be used to generate Horadam sequences.

The impacts of biological invasions

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Bethe Ansatz calculation of the spectral gap of the asymmetric exclusion process

open access: yes, 2003
We present a new derivation of the spectral gap of the totally asymmetric exclusion process on a half-filled ring of size L by using the Bethe Ansatz.

Terrestrial Analogs to Titan for Geophysical Research

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...
