Prevalence and characteristics of multi-modal hallucinations in people with psychosis who experience visual hallucinations.

Hallucinations can occur in single or multiple sensory modalities. Historically, greater attention has been paid to single sensory modality experiences with a comparative neglect of hallucinations that occur across two or more sensory modalities (multi-modal hallucinations). With growing evidence suggesting that visual hallucinations may be experienced along with other hallucinations, this study aimed to explore multi-modal hallucinations in a sample of people with psychotic disorders who reported visual ha...


Effects of modal shares on crash frequencies at aggregate level.

Long-range transportation plans often involve proposals for improvements/ changes in different modes of travel. This means that modal share of trips generated at each traffic analysis zone (TAZ) by mode of travel needs to be predicted/ forecasted for safety evaluation purposes. The objective of this research study is to develop a series of aggregate crash prediction models (ACPMs) that relate with the modal split step of the conventional four-step demand models.

Mental Imagery Follows Similar Cortical Reorganization as Perception: Intra-Modal and Cross-Modal Plasticity in Congenitally Blind.

Cortical plasticity in congenitally blind individuals leads to cross-modal activation of the visual cortex and may lead to superior perceptual processing in the intact sensory domains. Although mental imagery is often defined as a quasi-perceptual experience, it is unknown whether it follows similar cortical reorganization as perception in blind individuals. In this study, we show that auditory versus tactile perception evokes similar intra-modal discriminative patterns in congenitally blind compared with s...


Integrin αβ receptor targeting PET/MRI dual-modal imaging probe based on the Cu labeled manganese ferrite nanoparticles.

With the advent of positron emission tomography/magnetic resonance imaging (PET/MRI) scanner, PET/MRI dual-modal imaging will play more and more important role in the diagnosis of cancers and other diseases. Until now, there is no an approved PET/MRI dual-modal imaging probe. The goal of this work is to design and synthesize potential PET/MRI dual-modal imaging probe based on superparamagnetic manganese ferrite nanoparticles. We have developed superparamagnetic nanoparticles that have uniform size with 5 ...

Selectively exciting quasi-normal modes in open disordered systems.

Transmission through disordered samples can be controlled by illuminating a sample with waveforms corresponding to the eigenchannels of the transmission matrix (TM). But can the TM be exploited to selectively excite quasi-normal modes and so control the spatial profile and dwell time inside the medium? We show in microwave and numerical studies that spectra of the TM can be analyzed into modal transmission matrices of rank unity. This makes it possible to enhance the energy within a sample by a factor equal...

A tri-modal distribution of age-of-onset in female patients with myasthenia gravis is associated with the gender-related clinical differences.

A tri-modal distribution of age-at-onset emerged among females patients with myasthenia gravis (MG) in our database. This finding may be indicative of different gender-based disease mechanisms.

Delayed return of ejaculatory function in adolescent males treated with RPLND and adjuvant therapy for paratesticular rhabdomyosarcoma.

Due to the rarity of the disease, adverse events related to ejaculatory function following the management of paratesticular rhabdomyosarcoma (ptRMS) with multi-modal therapy in adolescents are rarely discussed. Two patients, age 14 and 15 at time of diagnosis were treated with multi-modal therapy with nerve-sparing retroperitoneal lymph node dissection (NS-RPLND), chemotherapy, and radiotherapy. Each developed ejaculatory dysfunction during the treatment period, which resolved 1 year after completion of all...

SCH-GAN: Semi-Supervised Cross-Modal Hashing by Generative Adversarial Network.

Cross-modal hashing maps heterogeneous multimedia data into a common Hamming space to realize fast and flexible cross-modal retrieval. Supervised cross-modal hashing methods have achieved considerable progress by incorporating semantic side information. However, they heavily rely on large-scale labeled cross-modal training data which are hard to obtain, since multiple modalities are involved. They also ignore the rich information contained in the large amount of unlabeled data across different modalities, w...

Jacobi circle and annular polynomials: modal wavefront reconstruction from wavefront gradient.

Jacobi circle polynomials, which are orthogonal on the unit circle with orthogonal radial derivatives, have been developed previously. As the classical Zernike mode can be represented as a linear combination of Jacobi modes, Zernike wavefront modes can be reconstructed using Jacobi modes. Comparison of the Jacobi and Zernike modes for the modal approach indicates that a modal approach incorporating the Gram matrix with the Jacobi modes has potential application in high-sampling wavefront gradient sensors. T...

Bi-Modal Arterial Compliance Probe for Calibration-Free Cuffless Blood Pressure Estimation.

We propose a calibration-free method and system for cuffless blood pressure (BP) measurement from superficial arteries. A prototype device with bi-modal probe arrangement was designed and developed to estimate carotid BP - an indicator of central aortic pressure.

Real-time dual-modal vein imaging system.

In this paper, we present a vein imaging system to combine reflectance mode visible spectrum images (VIS) with transmission mode near-infrared (NIR) images in real time. Clear vessel localization is achieved in this manner with combined NIR-VIS dual-modal imaging.

Neural practice effect during cross-modal selective attention: Supra-modal and modality-specific effects.

Practice and experiences gradually shape the central nervous system, from the synaptic level to large-scale neural networks. In natural multisensory environment, even when inundated by streams of information from multiple sensory modalities, our brain does not give equal weight to different modalities. Rather, visual information more frequently receives preferential processing and eventually dominates consciousness and behavior, i.e., visual dominance. It remains unknown, however, the supra-modal and modali...

HyperDense-Net: A hyper-densely connected CNN for multi-modal image segmentation.

Recently, dense connections have attracted substantial attention in computer vision because they facilitate gradient flow and implicit deep supervision during training. Particularly, DenseNet, which connects each layer to every other layer in a feed-forward fashion, has shown impressive performances in natural image classification tasks. We propose HyperDenseNet, a 3D fully convolutional neural network that extends the definition of dense connectivity to multi-modal segmentation problems. Each imaging modal...

Affect recognition from facial movements and body gestures by hierarchical deep spatio-temporal features and fusion strategy.

Affect presentation is periodic and multi-modal, such as through facial movements, body gestures, and so on. Studies have shown that temporal selection and multi-modal combinations may benefit affect recognition. In this article, we therefore propose a spatio-temporal fusion model that extracts spatio-temporal hierarchical features based on select expressive components. In addition, a multi-modal hierarchical fusion strategy is presented. Our model learns the spatio-temporal hierarchical features from video...

Assessing cross-modal target transition effects with a visual-auditory oddball.

Prior research has shown contextual manipulations involving temporal and sequence related factors significantly moderate attention-related responses, as indexed by the P3b event-related-potential, towards infrequent (i.e., deviant) target oddball stimuli. However, significantly less research has looked at the influence of cross-modal switching on P3b responding, with the impact of target-to-target cross-modal transitions being virtually unstudied. To address this gap, this study recorded high-density (256 e...

Cross-modal cueing effects of visuospatial attention on conscious somatosensory perception.

The impact of visuospatial attention on perception with supraliminal stimuli and stimuli at the threshold of conscious perception has been previously investigated. In this study, we assess the cross-modal effects of visuospatial attention on conscious perception for near-threshold somatosensory stimuli applied to the face.

Defining the Mechanistic Binding of Viral Particles to a Multi-Modal Anion Exchange Resin.

A multi-tiered approach to determine the binding mechanism of viral clearance utilizing a multi-modal anion exchange resin was applied to a panel of four viral species that are typically used in validating viral clearance studies (i.e., X-MuLV, MVM, REO3, and PrV). First, virus spiked buffer-only experiments were conducted to evaluate the virus's affinity for single mode and multi-modal chromatography resins under different buffer conditions in a chromatography column setting. From these results we hypothes...

We have developed and applied innovative image and electrophysiology processing methods to identify candidate biomarkers from MRI, EEG, and multi-modal data. Based on heterogeneous biomarkers, we present novel analytic tools designed to ...

400-Gbit/s QPSK free-space optical communicationlink based on four-fold multiplexing of Hermite-Gaussian or Laguerre-Gaussian modes by varying both modal indices.

We experimentally demonstrate the four-fold multiplexing of Hermite-Gaussian (HG) or Laguerre-Gaussian (LG) modes to achieve a 400 Gbit/s quadrature-phase-shift-keyed (QPSK) free-space optical communication link. In this experiment, both modal indices for the HG and LG modes are simultaneously utilized to achieve a larger potential orthogonal modal space. Moreover, we also investigate and compare the effects of aperture size, lateral displacement, and rotation on the system. We measure the degree of perfor...

One-step preparation of nano-in-micro poly(vinyl alcohol) embolic microspheres and used for dual-modal T/T-weighted magnetic resonance imaging.

It is crucial to develop dual or multi-modal self-imaging embolic microspheres to evaluate the effects of transcatheter arterial embolization therapy of tumor. However, the preparation of such hybrid microspheres always involved in multiple steps or complicated conditions. Here, poly(vinyl alcohol) (PVA) hybrid microspheres with dual-modal T/T-weighted magnetic resonance imaging (MRI) have been prepared based on microfluidic technique in one step. GdO and FeO nanoparticles with a size of ~5nm act as T- and ...

Spatial receptive field shift by preceding cross-modal stimulation in the cat superior colliculus.

It has been known for some time that sensory information of one type can bias the spatial perception of another modality. However, there is a lack of evidence of this occurring in individual neurons. In this study, we found that the spatial receptive field (RF) of superior colliculus (SC) multisensory neurons could be dynamically shifted by a preceding stimulus in a different modality. The extent to which the RF shifted was dependent on both temporal and spatial gaps between preceding and following stimuli ...

Monitoring pipe wall integrity using fiber Bragg grating-based sensing of low-frequency guided ultrasonic waves.

Recent literature shows that low-frequency ultrasonic guided waves experience mode confinement and loss of axi-symmetry in pipes with axially uniform features such as eccentricity. Considering extended wall loss as a case of uniform eccentricity, this paper proposes to monitor pipe integrity by measuring changes to the modal structure of low-frequency axisymmetric L(0,2) longitudinal guided waves. Fiber Bragg gratings are shown to be effective in detecting changes to L(0,2) modal characteristics, providing ...

Investigating common coding of observed and executed actions in the monkey brain using cross-modal multi-variate fMRI classification.

Mirror neurons are generally described as a neural substrate hosting shared representations of actions, by simulating or 'mirroring' the actions of others onto the observers' own motor system. Since single neuron recordings are rarely feasible in humans, it has been argued that cross-modal multi-variate pattern analysis (MVPA) of non-invasive fMRI data is a suitable technique to investigate common coding of observed and executed actions, allowing researchers to infer the presence of mirror neurons in the hu...

Mechanistic Insights into Human Brain Impact Dynamics through Modal Analysis.

Although concussion is one of the greatest health challenges today, our physical understanding of the cause of injury is limited. In this Letter, we simulated football head impacts in a finite element model and extracted the most dominant modal behavior of the brain's deformation. We showed that the brain's deformation is most sensitive in low frequency regimes close to 30 Hz, and discovered that for most subconcussive head impacts, the dynamics of brain deformation is dominated by a single global mode. In...

Cycle-Consistent Deep Generative Hashing for Cross-Modal Retrieval.

In this paper, we propose a novel deep generative approach to cross-modal retrieval to learn hash functions in the absence of paired training samples through the cycle consistency loss. Our proposed approach employs adversarial training scheme to learn a couple of hash functions enabling translation between modalities while assuming the underlying semantic relationship. To induce the hash codes with semantics to the input-output pair, cycle consistency loss is further delved into the adversarial training to...
