Structural colours reflect individual quality: a meta-analysis [NEW RESULTS]
Ornamental colouration often communicates salient information to mates, and theory predicts covariance between signal expression and individual quality. This has borne out among pigment-based signals, but the potential for honesty in structural colouration is unresolved. Here I synthesised the available evidence to test this prediction via meta-analysis and found that, overall, the expression of structurally coloured sexual signals is positively associated with individual quality. The effects varied...

A novel framework for modeling the evolution of cross-scale ecological assembly [NEW RESULTS]
Community assembly can be driven by species' responses to environmental gradients, and interactions within (e.g., competition) and across (e.g., herbivory) clades. These ecological dynamics are mediated by species' traits, which are in turn shaped by past evolution. As such, identifying the drivers of species assembly is made difficult by the differing temporal and spatial scales of ecological and evolutionary dynamics. Two recent advances have emerged to address the cross-scale challenge of modeling...

Insights from a general, full-likelihood Bayesian approach to inferring shared evolutionary events from genomic data: Inferring shared demographic events is challenging [NEW RESULTS]
Factors that influence the distribution, abundance, and diversification of species can simultaneously affect multiple evolutionary lineages within or across communities. These include environmental changes and inter-specific ecological interactions that cause ranges of multiple, co-distributed species to contract, expand, or become fragmented. Such processes predict genetic patterns consistent with temporally clustered evolutionary events across species, such as synchronous population divergences...

Multivariate phenotypic divergence along an urbanization gradient [NEW RESULTS]
A growing body of evidence suggests that natural populations can evolve to better tolerate the novel environmental conditions associated with urban areas. Invariably, studies of adaptive divergence in urban areas examine only one or a few traits at a time from populations residing only at the most extreme urban and nonurban habitats. Thus, whether urbanization is driving divergence in many traits simultaneously in a manner that varies with the degree of urbanization remains unclear. To address this...

Internet-word compared with daily-word priming reduces attentional scope
Abstract This study tested whether one aspect of cognitive processing, namely visual attentional scope, was more narrow in an Internet environment compared to a daily-life environment. Words related to the Internet and words related to daily life were used as priming stimuli before participants had to respond to a Navon letter to assess attention to global vs. local targets. In Experiment 1, reaction time during the Navon task showed that global processing priority was greater...

Do sounds near the hand facilitate tactile reaction times? Four experiments and a meta-analysis provide mixed support and suggest a small effect size
Abstract The brain represents the space immediately surrounding the body differently to more distant parts of space. Direct evidence for this ‘peripersonal space’ representation comes from neurophysiological studies in monkeys, which show distance-dependent responses to visual stimuli in neurons with spatially coincident tactile responses. Most evidence for peripersonal space in humans is indirect: spatial- and distance-dependent modulations of reaction times and error rates in...

Recommendations for MRI technique in the evaluation of pelvic endometriosis: consensus statement from the Society of Abdominal Radiology endometriosis disease-focused panel
Abstract Endometriosis is a common entity causing chronic pain and infertility in women. The gold standard method for diagnosis is diagnostic laparoscopy, which is invasive and costly. MRI has shown promise in its ability to diagnose endometriosis and its efficacy for preoperative planning. The Society of Abdominal Radiology established a Disease-Focused Panel (DFP) to improve patient care for patients with endometriosis. In this article, the DFP performs a literature review and...

Low-contrast X-ray enhancement using a fuzzy gamma reasoning model
Abstract X-ray images play an important role in providing physicians with satisfactory information correlated to fractures and diseases; unfortunately, most of these images suffer from low contrast and poor quality. Thus, enhancement of the image will increase the accuracy of correct information on pathologies for an autonomous diagnosis system. In this paper, a new approach for low-contrast X-ray image enhancement based on brightness adjustment using a fuzzy gamma reasoning model...

Paths of the cervical instantaneous axis of rotation during active movements—patterns and reliability
Abstract The instantaneous helical axis (IHA) is a characteristic of neck movement that is very sensitive to changes in coordination and that has potential in the assessment of functional alterations. For its application in the clinical setting, normative patterns must be available, and its reliability must be established. The purpose of this work is to describe the continuous paths of the IHA during cyclic movements of flexion-extension (FE), lateral bending (LB), and axial rotation...

Facial plast Surg 2020; 36: 053-056DOI: 10.1055/s-0040-1702146Rhinoplasty can be a key part of facial feminization for transgender women. Commonly, the required results necessitate significant deprojection of the nose in addition to the reduction of contour irregularities and shaping of the nostrils to a more round appearance. Pitfalls can include disproportion of the tip anatomic subunits, inadvertent creation of epicanthal folds, soft tissue pollybeak creation, and hanging columella among others.[...]Thieme...

These patients have often had previous surgery and may have complicated medical histories. Reconstructing the septum is a necessary prerequisite to correcting the contour of the nose. With proper planning and thoughtful execution, patients suffering from disfiguring saddle noses can be safely operated on—even those with vasculitic diseases.[...]Thieme Medical...

The use of dorsal grafts or implants for augmentation of the dorsum is a mainstay of both functional and cosmetic rhinoplasty. Due to the cosmetically sensitive nature of the dorsum, and the relatively large amount of graft or implant material that is typically used, infections in this area can be particularly difficulty...
