Polarization‐Dependence of Nonlinear Optical Effects in Silicon: The Case of Ultrafast Processing

Advanced Physics Research, EarlyView.
The dependence of the input polarization for the nonlinear optical propagation in silicon is investigated theoretically and experimentally. The perturbative regime is examined using pump‐probe shadowgraphy and nonlinear transmission, whereas the case of permanent laser‐induced modifications is addressed using a combination of Raman micro‐spectroscopy ...

Determining the effects of cattle grazing treatments on Yosemite toads (Anaxyrus [=Bufo] canorus) in montane meadows.

PLoS ONE, 2013
Amphibians are experiencing a precipitous global decline, and population stability on public lands with multiple uses is a key concern for managers. In the Sierra Nevada Mountains (California, USA), managers have specifically identified livestock grazing

Growth dynamics, skeletochronology, and histovariability of the theropod dinosaur Berthasaura leopoldinae

The Anatomical Record, EarlyView.
Osteohistological sampling on different bones of theropod dinosaur documents discrepant age record, growth, and metabolism. This could result unprecise paleobiological inferences if samplings are based on single bones. However, multi‐bone sampling can attenuate these discrepancies, helping to infer growth dynamics and physiology of these extinct ...

An unusual titanosaur axis from the Upper Cretaceous of Brazil and its significance for sauropod anatomy and systematics

The Anatomical Record, EarlyView.
Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...

Oldest well‐preserved euprimate petrosal, from the early Eocene of India (Vastan Lignite Mine, Gujarat)

The Anatomical Record, EarlyView.
Abstract An exquisitely preserved, isolated partial petrosal with associated fragmentary stapes is described from the Vastan Lignite Mine (Gujarat, India), dated to the early Eocene (~54.5 Ma). Several anatomical traits (e.g., large petrosal plate; posterolateral entry of the internal carotid artery to the tympanic cavity; bony tubes surrounding the ...

Pest control by the public: Impact of hand-collecting on the abundance and demography of cane toads (Rhinella marina) at their southern invasion front in Australia

Global Ecology and Conservation, 2020
The population dynamics of an alien species can be heterogeneous across a geographically widespread invasion– and thus, the effectiveness of alternative control methods can vary.

Periportal Capsulotomy Shows Promising Short‐Term Outcomes Compared With an Interportal Capsulotomy for the Treatment of Femoroacetabular Impingement Syndrome in Borderline and Dysplastic Female Patients

Arthroscopy, EarlyView.
Purpose To compare patient‐reported outcomes (PROs) and revision rates between borderline and dysplastic women who underwent an interportal capsulotomy approach versus a capsular sparing periportal capsulotomy approach for the treatment of femoroacetabular impingement syndrome. Methods Female patients with a lateral center edge angle ≤25° who underwent

ANK1 and EPB41 Variants and The Risk of Glucocorticoid‐Induced Osteonecrosis

Arthritis &Rheumatology, EarlyView.
Objective Steroid‐induced osteonecrosis of the femoral head (SONFH) is a refractory skeletal disorder influenced by genetic and environmental factors. However, conclusive pathogenic genetic evidence remains elusive due to the limited exploration of rare damaging variants. In this study, we aimed to identify rare variants associated with SONFH.

Winter hibernation and UCHL1-p34cdc2 association in toad oocyte maturation competence. [PDF]

PLoS ONE, 2013
Currently, it is believed that toad oocyte maturation is dependent on the physiological conditions of winter hibernation. Previous antibody-blocking experiments have demonstrated that toad ubiquitin carboxyl-terminal hydrolase L1 (tUCHL1) is necessary ...
