Submerse: Visualizing Storm Surge Flooding Simulations in Immersive Display Ecologies

We present Submerse, an end-to-end framework for visualizing flooding scenarios on large and immersive display ecologies. Specifically, we reconstruct a surface mesh from input flood simulation data and generate a to-scale 3D virtual scene by incorporating geographical data such as terrain, textures, buildings, and additional scene objects. To optimize computation and memory performance for large simulation datasets, we discretize the data on an adaptive grid using dynamic quadtrees and support level-of-detail based rendering. Moreover, to provide a perception of flooding direction for a time instance, we animate the surface mesh by synthesizing water waves. As interaction is key for effective decision-making and analysis, we introduce two novel techniques for flood visualization in immersive systems: (1) an automatic scene-navigation method using optimal camera viewpoints generated for marked points-of-interest based on the display layout, and (2) an AR-based focus+context technique using an auxiliary display system. Submerse is developed in collaboration between computer scientists and atmospheric scientists. We evaluate the effectiveness of our system and application by conducting workshops with emergency managers, domain experts, and concerned stakeholders in the Stony Brook Reality Deck, an immersive gigapixel facility, to visualize a superstorm flooding scenario in New York City

Treatment of Automatic Negative Thoughts and Non-suicidal Self-injury (NSSI) Behavior in Borderline Personality Disorder Adolescents: Dialectical Behavior Therapy

Background: About 17 to 80% of borderline personality disorder (BPD) patients suffer repeated NSSI (most frequently, cutting/burning self-injury), while 46 to 92% of BPD patients attempt suicide. This study aimed to investigate the effectiveness of the condensed dialectic behavior in reducing automatic negative thoughts and its positive effects on non-suicidal self-injury (NSSI) behavior in borderline personality disorder (BPD). Methods: A semi-experimental study with pre-and post-tests is going on with both an experimental group and a control group. In 2019, twenty-two BPD adolescents who attended the treatment clinic) Masire Sabz), district 8, Tehran, were divided into two groups. Two questionnaires of automatic negative thoughts and non-suicidal suicide self-injury were administered before and after the intervention. This study employed SPSS 23 with Levene's test, as well as ANOVA to analyze the data. During the intervention group, twelve 90-minute sessions took place with participants in the intervention group, which followed a protocol adapted from a standard DBT protocol for BD participants in the control group waited for a treatment appointment. Results: The results showed that the scores of the intervention group significantly decreased in the Automatic negative thoughts and non-suicidal self-injury after 2 months of the intervention (Pvalue<0.001). Conclusions: It can be concluded that dialectical behavior therapy was effective on automatic negative thoughts and non-suicidal self-injury (NSSI) behavior among borderline personality disorder adolescents. Keywords: Automatic negative thoughts, Non-suicidal self-injury (NSSI) behavior, Borderline personality disorder

Combination of surgical excision and custom designed silicon pressure splint therapy for keloids on the helical rim

Keloids are defined as dermal fibrotic lesions which are considered an aberration of the wound healing process. Their etiology and pathogenesis are poorly understood. Different treatment modalities are described in the literature depending on the morphology and size of the keloid. We report a case of a large ear keloid on the helical rim which was successfully treated with surgery and a custom designed silicon pressure clip

Base Region Topology of Turbulent Wake around Finite Wall-Mounted Cylinder with Application of Low Order Flow Representation

Turbulent flow topology around a rectangular cylinder with h/d=8 is characterized by either dipole or quadrupole mean wake depending on the turbulent boundary layer thickness. This study investigates the physical and mathematical mechanisms giving rise to the two distinct types of flow by considering the phase-averaged velocity field. It was found that the vortex stretching and tilting and the time-averaged representation of tilted vortex shedding are the key terms distinguishing between the dipole and quadrupole wake structures. The other objective is to develop a procedure to estimate the higher-rank low order flow based on Extended Proper Orthogonal Decomposition. Within this technique, the global velocity flow can be reconstructed with correlated surface pressure sensors to have a closer look at the mechanisms leading to dipole and quadrupole wakes. It was observed that optimum choice of sensor locations needs analytical considerations to improve the ability of pressure probes in capturing the coherent structures of interest

Multiscale entropy (MSE) and multicomponent complexity (MCC)

Multiscale entropy (MSE) is a powerful method for determining the complexity of random time series. In this paper we, investigate the cardiac heart interbeat interval (RR) time series by introducing a new method based on MSE, called multicomponent complexity (MCC) and find clear difference between healthy samples and samples with Congestive heart failure (CHF) disease

Simple and Efficient Rout for Synthesis of Spinel Nanopigments

Nano-sized CoxMg1−xAl2O4 (x = 0, 0.1, 0.2, 0.4, 0.6, 0.8, and 1) inorganic pigments were synthesized via combustion method using β-alanine, as a single and novel fuel, at 800°C in open furnace. The obtained powders were characterized by means of X-ray diffraction (XRD), energy dispersive X-ray (EDX) elemental analysis, diffuse reflectance spectrum (DRS), CIE L*a*b* color measurements, and scanning electron microscope (SEM). XRD patterns show that all calcined powders have single phase cubic spinel structure. EDX analysis revealed the composition of desired spinels. The diffuse reflectance spectra of the CoxMg1−xAl2O4 (x > 0) pigments confirmed the presence of tetrahedrally coordinated Co2+ ions in the spinel lattice. The colorimetric data pointed out the formation of blue pigments (for x > 0), corresponding to highly negative values of b*, and the bluest color was produced for x = 0.8 and 1. SEM images showed nanoparticles with less than 30 nm crystallite size and flakes-like appearance of all synthesized powders
