Dual‐Channel Interdigitated Aptamer‐Based Sensors for Rapid Small‐Molecule Detection in Biofluids

Angewandte Chemie International Edition, EarlyView.
An electrochemical aptamer sensing chip employs dual interdigitated electrodes and selective self‐assembled monolayer removal to convert small‐molecule recognition into robust “signal‐off/on” responses. This dual‐channel signal conversion minimizes background noise and accelerates probe diffusion, enabling rapid (as fast as 5–30 min), low‐volume ...

The coelurosaur theropods of the Romualdo formation, early Cretaceous (Aptian) of Brazil: Santanaraptor placidus meets Mirischia asymmetrica

The Anatomical Record, EarlyView.
Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.

Relationship between sexist attitudes and positive and negative emotional variables

Feminismo/s, 2015
The investigation had two goals: (1) to analyze the relations between sexism (HS-hostile, BS-benevolent, AS-ambivalent) and positive and negative emotions; and (2) to identify predictor variables of HS and BS. The sample comprised 941 students from 14 to

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 ...

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

The Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

ASCA Observations of Two Ultraluminous IRAS Galaxies: IRAS 15307+3252 and IRAS 20460+1925 [PDF]

Publications of the Astronomical Society of Japan, 1997
We report on ASCA observations of two ultraluminous far-infrared galaxies, IRAS 15307+3252 and IRAS 20460+1925. An X-ray flux of 1.53 × 10−12 erg cm−2 s−1 in the 2–10 keV band was detected from IRAS 20460+1925. The continuous spectrum is well represented by a power law with a photon index of 1.99+0.18−0.15 and excess photoelectric absorption by a ...

Inter‐ and intraspecific variation in theropod dinosaur dental microwear and its palaeoecological implications

The Anatomical Record, EarlyView.
Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).
