Time tells: plasticity and developmental asynchrony underlie trait variation in a dune‐building grass

open access: yesOikos, EarlyView.
Habitat‐modifying plants engineer landscapes through plant‐environment feedbacks. The strength of these feedbacks is determined by above‐ and below‐ground traits shaping landscape morphology. Besides interspecific differences, recent findings highlight that intraspecific trait variation, such as shoot density, can also influence landscape morphology ...

Assessment of Artificial Intelligence Models for Estimating Lengths of Gradually Varied Flow Profiles

open access: yesComplexity, 2021
The study of water surface profiles is beneficial to various applications in water resources management. In this study, two artificial intelligence (AI) models named the artificial neural network (ANN) and genetic programming (GP) were employed to ...

Sedimentation and Type I X-ray Bursts at Low Accretion Rates [PDF]

open access: yes, 2006
Neutron stars, with their strong surface gravity, have interestingly short timescales for the sedimentation of heavy elements. Motivated by observations of Type I X-ray bursts from sources with extremely low persistent accretion luminosities, $L_X < 10 ...

Flexural performance of concrete‐filled steel tubular beams with wood chip aggregate

open access: yesStructural Concrete, EarlyView.
Abstract This study investigates the flexural performance of concrete‐filled steel tubular (CFST) beams with partial replacement of aggregates by wood chips (0%–25%) through experimental and numerical analysis. This study is novel in that it experimentally and numerically investigates the flexural behavior of CFST beams with partial replacement of ...

Some Fixed Point Results in GP-Metric Spaces

open access: yesJournal of Applied Mathematics, 2012
Following a recent paper of Zand and Nezhad (2011), we establish some fixed point results in GP-metric spaces. The presented theorems generalize and improve several existing results in the literature. Also, some examples are presented.

Arts journalism and exiled writers: a case study of fugal, reflexive practice

open access: yesPacific Journalism Review, 2009
Arts journalism and reflective practice intersect in a new field of ‘journalism as research’ (Bacon 2006). This article takes an innovative approach informed by the multimodal, musical and psychogenic fugue to discuss a case study of arts journalism ...

Multiple Sub-Jet Model of Gamma Ray Bursts and Possible Origin of X-ray Precursors and Post-cursors [PDF]

open access: yes, 2000
We assume that internal shocks of Gamma Ray Bursts (GRBs) consist of multiple sub-jets with a collimation half-angle $\sim {\rm several }\times\gamma_i^{-1}$, where $\gamma_i$ is the Lorenz factor of each sub-jet.

Displaced Impacts: Visibility, Care, and Humanitarian Filmmaking in Iran

open access: yesAmerican Anthropologist, EarlyView.
ABSTRACT Socially oriented documentary films are increasingly expected to articulate “impact” goals to gain international distribution, yet what counts as impact for those represented remains contested. This article examines how narratives about working and displaced youth in Iran are produced and circulated through social filmmaking.

Endometrial cavity-myoma fistula after uterine artery embolization diagnosed by pelvic MRI: case report

open access: yesRadiology Case Reports, 2021
Uterine cavity-myoma fistula is a rare entity which has scarcely been reported in the literature. They are mainly secondary to a treatment and intervention.

Chandra observation of the fast X-ray transient IGR J17544-2619: evidence for a neutron star?

open access: yes, 2005
IGR J17544-2619 belongs to a distinct group of at least seven fast X-ray transients that cannot readily be associated with nearby flare stars or pre-main sequence stars and most probably are X-ray binaries with wind accretion.
