A Dynamic Convolution Kernel Generation Method Based on Regularized Pattern for Image Super-Resolution.

Sensors (Basel) 2022 Jun 1;22(11). Epub 2022 Jun 1.

Institute of Systems Science, National University of Singapore, Singapore 119615, Singapore.

Image super-resolution aims to reconstruct a high-resolution image from its low-resolution counterparts. Conventional image super-resolution approaches share the same spatial convolution kernel for the whole image in the upscaling modules, which neglect the specificity of content information in different positions of the image. In view of this, this paper proposes a regularized pattern method to represent spatially variant structural features in an image and further exploits a dynamic convolution kernel generation method to match the regularized pattern and improve image reconstruction performance.

Disconnections in personal neglect.

Brain Struct Funct 2022 Jun 7. Epub 2022 Jun 7.

NPSY-Lab.VR, Department of Human Sciences, University of Verona, Lungadige Porta Vittoria, 17, 37129, Verona, Italy.

Personal neglect is a disorder in the perception and representation of the body that causes the patients to behave as if the contralesional side of their body does not exist. This clinical condition has not been adequately investigated in the past as it has been considered a symptom of unilateral spatial neglect, which has mainly been studied with reference to extrapersonal space. Only a few studies with small samples have investigated the neuroanatomical correlates of personal neglect, and these have mainly focused on discrete cortical lesions and modular accounts, as well as being based on the hypothesis that this disorder is associated with somatosensory and spatial deficits.

Virtual reality for the assessment and rehabilitation of neglect: where are we now? A 6-year review update.

Virtual Real 2022 May 30:1-42. Epub 2022 May 30.

Applied Technology for Neuro-Psychology Lab, IRCCS Istituto Auxologico Italiano, Milan, Italy.

Unilateral spatial neglect (USN) is a frequent repercussion of a cerebrovascular accident, typically a stroke. USN patients fail to orient their attention to the contralesional side to detect auditory, visual, and somatosensory stimuli, as well as to collect and purposely use this information. Traditional methods for USN assessment and rehabilitation include paper-and-pencil procedures, which address cognitive functions as isolated from other aspects of patients' functioning within a real-life context.

Predicting the prognosis of unilateral spatial neglect using magnetic resonance imaging in patients with stroke: A systematic review.

Brain Res 2022 Aug 26;1789:147954. Epub 2022 May 26.

Graduate School of Humanities and Social Sciences, Hiroshima University, Hiroshima, Japan.

Accurate prognosis prediction of unilateral spatial neglect (USN) is clinically important for identifying patients with potentially poor recovery who require more intensive rehabilitation and early interdisciplinary support for residual disabilities. Magnetic resonance imaging (MRI)-based neuroimaging can provide clinicians with high-quality and high-resolution neuroanatomical information from the aspects of neuroanatomy, integrity of the neural tract, and neural functional connectivity. Although the application of MRI is expected beneficial for the prognosis prediction of USN, there is still no systematic review of its usefulness, and it has not been standardized in the field of stroke rehabilitation.

Population spatialization at building scale based on residential population index-A case study of Qingdao city.

PLoS One 2022 26;17(5):e0269100. Epub 2022 May 26.

College of Geodesy and Geomatics, Shandong University of Science and Technology, Shandong, China.

The study of population spatialization has provided important basic data for urban planning, development, environment and other issues. With the development of urbanization, urban residential buildings are getting higher and higher, and the difference between urban and rural population density is getting larger and larger. At present, most population spatial studies adopt the grid scale, and the population in buildings is evenly divided into various grids, which will lead to the neglect of the population distribution in vertical space, and the authenticity is not strong.

Effects of Virtual Reality-Based Multimodal Audio-Tactile Cueing in Patients With Spatial Attention Deficits: Pilot Usability Study.

JMIR Serious Games 2022 May 25;10(2):e34884. Epub 2022 May 25.

Gerontechnology & Rehabilitation Group, University of Bern, Bern, Switzerland.

Background: Virtual reality (VR) devices are increasingly being used in medicine and other areas for a broad spectrum of applications. One of the possible applications of VR involves the creation of an environment manipulated in a way that helps patients with disturbances in the spatial allocation of visual attention (so-called hemispatial neglect). One approach to ameliorate neglect is to apply cross-modal cues (ie, cues in sensory modalities other than the visual one, eg, auditory and tactile) to guide visual attention toward the neglected space.

Improved drug-target interaction prediction with intermolecular graph transformer.

Brief Bioinform 2022 May 5. Epub 2022 May 5.

Microsoft Research Asia, Beijing, 100080, China.

The identification of active binding drugs for target proteins (referred to as drug-target interaction prediction) is the key challenge in virtual screening, which plays an essential role in drug discovery. Although recent deep learning-based approaches achieve better performance than molecular docking, existing models often neglect topological or spatial of intermolecular information, hindering prediction performance. We recognize this problem and propose a novel approach called the Intermolecular Graph Transformer (IGT) that employs a dedicated attention mechanism to model intermolecular information with a three-way Transformer-based architecture.

Endpoints and viewpoints on spatial neglect.

J Neuropsychol 2022 Jun 4;16(2):299-305. Epub 2022 May 4.

Department of Rehabilitation Medicine, Sapporo Medical University School of Medicine, Sapporo, Japan.

In this issue of the Journal of Neuropsychology, Abe and Ishiai (2022) report an experiment designed to probe the subjective experience of line bisection in neglect. A re-analysis of their data can also offer insights into how best to characterise neglect performance for this and other tasks. We show that sensitive measures of neglect can be obtained by quantifying the difference in the influence (or 'weighting') that each endpoint has on the response. Read More

SIM reconstruction framework for high-speed multi-dimensional super-resolution imaging.

Opt Express 2022 Mar;30(7):10877-10898

Structured illumination microscopy (SIM) holds great promise for live cell imaging applications due to its potential to obtain multidimensional information such as intensity, spectrum and polarization (I, λ , p) at high spatial-temporal resolution, enabling the observation of more complex dynamic interactions between subcellular structures. However, the reconstruction results of polarized samples are prone to artifacts because all current SIM reconstruction frameworks use incomplete imaging models which neglect polarization modulation. Such polarization-related artifacts are especially prevalent for SIM reconstruction using a reduced number of raw images (RSIM) and severely undermine the ability of SIM to capture multi-dimensional information.

The orienting response drives pseudoneglect-Evidence from an objective pupillometric method.

Cortex 2022 06 2;151:259-271. Epub 2022 Apr 2.

Experimental Psychology, Helmholtz Institute, Utrecht University, Utrecht, the Netherlands.

Spatial attention is generally slightly biased leftward ("pseudoneglect"), a phenomenon typically assessed with paper-and-pencil tasks, limited by the requirement of explicit responses and the inability to assess on a subsecond timescale. Pseudoneglect is often stable within experiments, but differs vastly between investigations and is sometimes directed to the left, sometimes to the right. To date, no exhaustive explanation to this phenomenon has been provided. Read More

Group-level stability but individual variability of neurocognitive status after awake resections of right frontal IDH-mutated glioma.

Sci Rep 2022 04 12;12(1):6126. Epub 2022 Apr 12.

Department of Neurosurgery, Lariboisière Hospital, AP-HP, 2 rue Ambroise Paré, 75010, Paris, France.

Awake surgery for low-grade gliomas is currently considered the best procedure to improve the extent of resection and guarantee a "worth living life" for patients, meaning avoiding not only motor but also cognitive deficits. However, tumors located in the right hemisphere, especially in the right frontal lobe, are still rarely operated on in awake condition; one of the reasons possibly being that there is little information in the literature describing the rates and nature of long-lasting neuropsychological deficits following resection of right frontal glioma. To investigate long-term cognitive deficits after awake surgery in right frontal IDH-mutated glioma. Read More
