Motor resonance processes that occur when observing an individual perform an action may be modulated by acquired visuomotor expertise. We used the event-related potential (EEG/ERP) technique to investigate the ability to automatically recognize a subtle difference between very similar novel contemporary dance movements. Twelve professional dancers and twelve non-dancers were shown 212 pairs of videos of complex whole-body movements that lasted 3seconds. The second of each pair was the repetition of the previous movement or a slight variation of it (deviance)...

The face of evolutionary biology is changing: from reconstructing and analysing the past to predicting future evolutionary processes. Recent developments include prediction of reproducible patterns in parallel evolution experiments, forecasting the future of individual populations using data from their past, and controlled manipulation of evolutionary dynamics. Here we undertake a synthesis of central concepts for evolutionary predictions, based on examples of microbial and viral systems, cancer cell populations, and immune receptor repertoires...

This paper develops a novel method to address the structural noise in samples for image classification. Recently, regression related classification methods have shown promising results when facing the pixel-wise noise. However, they become weak in coping with the structural noise due to ignoring of relationships between pixels of noise image. Meanwhile, most of them need to implement the iterative process for computing representation coefficients, which leads to the high time consumption. To overcome these problems, we exploit a latent pattern model called Low-Rank Latent Pattern Approximation (LLPA) to reconstruct the test image having structural noise...

Ischemic necrosis is a feared complication of acute gastric volvulus, occurring in 11% of patients presenting with the condition and responsible for mortality in 30%. In such cases, there are few well-validated options for surgical reconstruction. We present the case of a 77-year-old woman with intraabdominal mesenteroaxial gastric volvulus with segmental ischemic gastric necrosis who underwent wedge gastrectomy and hand-sewn gastrogastrostomy. She did well postoperatively and experienced no significant gastrointestinal complications...

Biogenesis and dynamics of thylakoid membranes likely involves membrane fusion events. Membrane attachment of the inner membrane-associated protein of 30 kDa (IM30) affects the structure of the lipid bilayer, finally resulting in membrane fusion. Yet, how IM30 triggers membrane fusion is largely unclear. IM30 monomers pre-assemble into stable tetrameric building blocks, which further align to form oligomeric ring structures, and differently sized IM30 rings bind to membranes. Based on a 3D reconstruction of IM30 rings, we locate the IM30 loop 2 region at the bottom of the ring and show intact membrane binding but missing fusogenic activity of loop 2 mutants...

Eyebrows play an important role in face expression and facial mimics by virtue of muscle contraction. Defects or deformity of the eyebrows result in abnormal facial expressions, and may lead to aesthetic issues for patients. The objective of this study is to report the case of a patient, with a congenital skin pigmented nevus at the right side of the eyebrow treated with direct surgical resection and followed by immediate reconstruction of the eyebrow with a V-Y advancement pedicle flap based on the orbicularis oculi muscle...

BACKGROUND: Binder syndrome is a rare congenital malformation with a flat facial profile especially a depressed nose. Rhinoplasty plays an important part in the multidisciplinary surgical protocol. Different materials have been proposed to reconstruct nasal framework. But fewer evidence concerns which graft can achieve more stable and appreciated nasal contour. In this article, the authors reported surgical details and experience of nasal framework reconstruction of Binder syndrome, compare the esthetic outcomes of 2 grafts: autologous costal cartilage and L-shaped silicone covered with auricular cartilage...

BACKGROUND: To investigate whether outer retinal reflectivity on en-face Optical coherence tomography (OCT) can be considered as an estimator of cone density measured in the same area. METHODS: Forty-one points of comparisons were studied in 9 eyes (n = 6 patients) presenting maculopathies with various degrees of impairment of the photoreceptor layer. The inner segment ellipsoid zone (EZ), interdigitation zone (IZ), and retinal pigment epithelium (RPE) reflectivity were measured on coronal reconstruction of the photoreceptor layer using homemade dedicated software (Matlab, MathWorks Inc...

OBJECTIVE: Facial keloids commonly occur in young patients. Multiple keloid masses often converge into a large lesion on the face, representing a significant obstacle to keloid mass excision and reconstruction. We describe a new surgical method that excises the keloid mass and resurfaces the wound by saving the keloid skin as a skin flap during facial keloid treatment. METHODS: Forty-five patients with facial keloids were treated in our department between January 2013 and January 2016...

Binary code learning, a.k.a. hashing, has received increasing attention in large-scale visual search. By transforming high-dimensional features to binary codes, the original Euclidean distance is approximated via Hamming distance. More recently, it is advocated that it is the manifold distance, rather than the Euclidean distance, that should be preserved in the Hamming space. However, it retains as an open problem to directly preserve the manifold structure by hashing. In particular, it needs first to build the local linear embedding in the original feature space, and then quantize such embedding to binary codes...

INTRODUCTION: With the present disparity between organ availability and recipient demands, we reported our experience in transplanting kidneys with renal artery aneurysm after back-table reconstruction. METHODS: Four patients were identified. The repair consisted of excision of the aneurysm with ostial closure, and for one of the cases, an ovarian vein patch was used. We reviewed the safety and outcomes of this procedure. All donors were asymptomatic before surgery and were diagnosed incidentally during living donor evaluation...

Tingting Jin, Xiaolan Qiu, Donghui Hu, Chibiao Ding
Multichannel synthetic aperture radar (SAR) is a breakthrough given the inherent limitation between high-resolution and wide-swath (HRWS) faced with conventional SAR. This paper aims to obtain unambiguous imaging of static scenes and moving targets with the first Chinese dual-channel spaceborne SAR sensor. We propose an integrated imaging scheme with the dual-channel echoes. In the imaging scheme, the subspace-based error estimation algorithm is first applied to the spaceborne multichannel SAR system, followed by the reconstruction algorithm prior to imaging...

Philip II, father of Alexander the Great, succeeded his brother, Perdiccas III, to the throne of Macedonia in 360 BC. He has been described by historians as a generous king and military genius who managed to achieve his ambitious plans by expanding the Macedonian city-state over the whole Greek territory and the greater part of the Balkan Peninsula. The aim of our study was to present the evidence with regard to the facial injury of King Philip II of Macedonia and discuss the treatment of the wound by his famous physician, Critobulos...

Predictive coding suggests that the brain infers the causes of its sensations by combining sensory evidence with internal predictions based on available prior knowledge. However, the neurophysiological correlates of (pre-)activated prior knowledge serving these predictions are still unknown. Based on the idea that such pre-activated prior knowledge must be maintained until needed we measured the amount of maintained information in neural signals via the active information storage (AIS) measure. AIS was calculated on whole-brain beamformer-reconstructed source time-courses from magnetoencephalography (MEG) recordings of 52 human subjects during the baseline of a Mooney face/house detection task...

The field of hand surgery is constantly evolving to meet the challenges of repairing intricate anatomical structures with limited availability of donor tissue. The past 10 years have seen an exponential growth in tissue engineering, which has broadened the perspectives of tackling these age-old problems. Various fabrication techniques such as melt electrospinning and fused deposition modelling have been employed to synthesize 3-dimensional bioscaffolds that can be used to replace lost tissue. These bioscaffolds with strategic biomimicry have been shown to allow for integrative and functional repair of tissue injuries...

The scars of face and scalp caused by burning often show as 1 large facial-scalp scar. The deltopectoral flap was recognized as one of the first choices for the facial scar reconstruction. However, this flap cannot cross the level of zygomatic arch traditionally when it was transferred with pedicle. When the flap reconstructed the facial-scalp scars with expanded random scalp flap, another flap was often needed to reconstruct the remaining temple and forehead scars. The authors reviewed 24 patients of large facial-scalp scars reconstructed by expanded pedicled deltopectoral flap and scalp flap with several technique improvements...

Visual memory for faces has been extensively researched, especially regarding the main factors that influence face memorability. However, what we remember exactly about a face, namely, the pictorial content of visual memory, remains largely unclear. The current work aims to elucidate this issue by reconstructing face images from both perceptual and memory-based behavioural data. Specifically, our work builds upon and further validates the hypothesis that visual memory and perception share a common representational basis underlying facial identity recognition...

INTRODUCTION: Zygomatic-orbital complex fractures are the most common facial traumas that can result in severe esthetic and functional sequelae. Surgical correction of these fractures is a delicate approach and prototyping is an excellent tool to facilitate this procedure. PRESENTATION OF CASE: A 27-year-old man, a motorcycle accident victim, was hospitalized in the intensive care unit for 30days. After this period, facial fractures were treated surgically, leaving sequelae such as enophthalmos, dystopia and loss of projection of the zygomatic arch...

OBJECTIVE: During the last decade, face allotransplantation has been shown to be a revolutionary reconstructive procedure for severe disfigurements. However, offer to patients remains limited due to lifelong immunosuppression. To move forward in the field, a new pathway in tissue engineering is proposed. BACKGROUND: Our previously reported technique of matrix production of a porcine auricular subunit graft has been translated to a human face model. METHODS: 5 partial and 1 total face grafts were procured from human fresh cadavers...
