Conveying facial expressions to blind and visually impaired persons through a wearable vibrotactile device (2018)

In face-to-face social interactions, blind and visually impaired persons (VIPs) lack access to nonverbal cues like facial expressions, body posture, and gestures, which may lead to impaired interpersonal communication. In this study, a wearable sensory substitution device (SSD) consisting of a head mounted camera and a haptic belt was evaluated to determine whether vibrotactile cues around the waist could be used to convey facial expressions to users and whether such a device is desired by VIPs for use in daily living situations. Ten VIPs (mean age: 38.8, SD: 14.4) and 10 sighted persons (SPs) (mean age: 44.5, SD: 19.6) participated in the study, in which validated sets of pictures, silent videos, and videos with audio of facial expressions were presented to the participant. A control measurement was first performed to determine how accurately participants could identify facial expressions while relying on their functional senses. After a short training, participants were asked to determine facial expressions while wearing the emotion feedback system. VIPs using the device showed significant improvements in their ability to determine which facial expressions were shown. A significant increase in accuracy of 44.4% was found across all types of stimuli when comparing the scores of the control (mean±SEM: 35.0±2.5%) and supported (mean±SEM: 79.4±2.1%) phases. The greatest improvements achieved with the support of the SSD were found for silent stimuli (68.3% for pictures and 50.8% for silent videos). SPs also showed consistent, though not statistically significant, improvements while supported. Overall, our study shows that vibrotactile cues are well suited to convey facial expressions to VIPs in real-time. Participants became skilled with the device after a short training session. Further testing and development of the SSD is required to improve its accuracy and aesthetics for potential daily use.
Discomfort glare under automotive conditions – spectral behavior and mechanisms (2011)

A new experimental apparatus was constructed to study the spectral behaviour of discomfort glare and to explore its visual mechanisms. The apparatus includes two quasi-monochromatic optical channels to project quasi-monochromatic and quasi-bichromatic glare stimuli. Observation geometries and luminance levels address the practical application of automotive headlamps. To model oncoming automotive headlamps, a typical angular size of =0.1° was chosen on a typical background luminance of LB=0.1 cd/m2 and at a typical retinal eccentricity of =4.3° to the left of the fixation point where car headlamps tend to appear. The value of  =0° has also been considered for comparison. The de Boer value of 5 (just admissible) was chosen which is relevant for night time traffic and easy to set by the observer by adjusting a neutral density filter wheel. The apparatus consists of two interference filter wheels (10 nm HBW) constituting two optical channels each producing a quasi-monochromatic beam from the two Xenon short arc high-pressure lamps, a beam splitter to unite the two channels to produce a quasi-bichromatic beam. The glare source is a changeable 0.1°-0.5° aperture inside a glare observation booth illuminated by four dimmable white LEDs. The device is calibrated by a spectroradiometer looking into the booth and measuring spectral radiance at a white standard at the position of the subject’s left eye. Discomfort glare results have shown effects of both additive and opponent cone mechanisms. Opponent cone mechanisms e.g. |L-M| cause spectral non-additivity to be predicted by a new discomfort glare model. Due to the mesopic surround, the rod effect cannot be excluded.
The Human Mucin MUC4 Is Transcriptionally Regulated by Caudal-related Homeobox, Hepatocyte Nuclear Factors, Forkhead Box A, and GATA Endodermal Transcription Factors in Epithelial Cancer Cells (2007)

The human gene MUC4 encodes a large transmembrane mucin that is developmentally regulated and expressed along the undifferentiated pseudostratified epithelium, as early as 6.5 weeks during fetal development. Immunohistochemical analysis of Muc4 expression in developing mouse lung and gastrointestinal tract showed a different spatio-temporal pattern of expression before and after cytodifferentiation. The molecular mechanisms governing MUC4 expression during development are, however, unknown. Hepatocyte nuclear factors (HNF), forkhead box A (FOXA), GATA, and caudal-related homeobox transcription factors (TFs) are known to control cell differentiation of gut endoderm derived-tissues during embryonic development. They also control the expression of cell- and tissue-specific genes and may thus control MUC4 expression. To test this hypothesis, we studied and deciphered the molecular mechanisms responsible for MUC4 transcriptional regulation by these TFs. Experiments using small interfering RNA, cell co-transfection, and site-directed mutagenesis indicated that MUC4 is regulated at the transcriptional level by CDX-1 and -2, HNF-1 alpha and -1 beta, FOXA1/A2, HNF-4 alpha and -4 gamma, and GATA-4, -5, and -6 factors in a cell-specific manner. Binding of TFs was assessed by chromatin immunoprecipitation, and gel-shift assays. Altogether, these results demonstrate that MUC4 is a target gene of endodermal TFs and thus point out an important role for these TFs in regulating MUC4 expression during epithelial differentiation during development, cancer, and repair.
Estimation of nutritional, phytochemical and antioxidant activity of seeds of musk melon (Cucumis melo) and water melon (Citrullus lanatus) and nutritional analysis of their respective oils (2015)

The dried seeds of musk melon (Cucumis melo) and water melon (Citrullus lanatus) were analyzed for different characteristics such as nutritional, phytochemical and antioxidant activity to understand its potential benefits. The nutritional analysis shows that the seeds are a good source of energy, carbohydrates, fat, proteins and minerals such as calcium, iron, magnesium, phosphorus and potassium. Phytochemical analysis reveals that the seeds are a good source of flavonoids, phenolics, saponins, alkaloids and other secondary metabolites. The oil of seeds was extracted by cold pressing and analyzed for various parameters such as iodine value, saponification value and fatty acid profile. The results revealed the high iodine value and presence of polyunsaturated fatty acids such as omega- 6 (linoleic acid), monounsaturated fatty acids such as omega- 9 (oleic acid). It also consists of saturated fatty acids such as palmitic acid and stearic acid. The seeds provide opportunities to develop as value added products, dietary supplements and medicines.

Predicting the Expansion Behavior of Filter Media (1986)

Models that have been used to predict the expansion of filter media are evaluated, and a new correlation, which represents an alternative approach to describing the velocity‐voidage relationship of particulately fluidized systems, is explained. The uses and limitations of this correlation are included.
Dissociation, Chemical Exchange, and the Proton Magnetic Resonance in Some Aqueous Electrolytes (1953)

The position of the proton magnetic resonance is concentration dependent in aqueous solutions of electrolytes yielding hydrogen containing ions. Chemical exchange averages the chemical shifts in the proton resonance position over the different chemical species. The averaged shifts observed are correlated with dissociation of the solute, and evidence is obtained in very concentrated solutions for the incomplete dissociation of HNO3, HClO4, and H2SO4 and for the formation of ion pairs of Na+OH−. A theoretical analysis of the relation between the magnetic absorption line shape and the chemical exchange frequency suggests that rather short chemical lifetimes can be measured; at least one can infer from the appearance of a single or complex resonance that the average lifetime is greater or less, respectively, than a determinable value in a range about 10−2 to 10−4 sec.
MAJOR CAROTENOIDS IN JUICES OF PONKAN MANDARIN AND LIUCHENG ORANGE (1994)

The identification and quantitation of major carotenoids in juices of Ponkan mandarin and Liucheng orange and their changes during harvesting were studied. Neoxanthin, violaxanthin, lutein, β-cryptoxanthin, α-carotene and β-carotene are the major carotenoids for Ponkan mandarin. During the harvesting period, the contents of violaxanthin, β-cryptoxanthin and β-carotene increase significantly. For Liucheng orange, neoxanthin, violaxanthin, lutein, antheraxanthin, β-cryptoxanthin, α-carotene and β-carotene are the major carotenoids. Among them, neoxanthin, violaxanthin, lutein, antheraxanthin and β-cryptoxanthin increase significantly during the harvesting period. The β-cryptoxanthin and β-carotene are the major contributors to the color of Ponkan mandarin juice while neoxanthin, violaxanthin, lutein and antheraxanthin are the major ones for the color of Liucheng orange juice.

Fingerprint pixel sensor array on a display (2016)

The fingerprint pixel sensor array was investigated for the application to the mobile phone. For the fingerprint sensing high resolution pixel array is necessary. Therefore, the readout voltage dependence on the resistance of the wires was investigated after composing 450th pixel array. The readout voltage was investigated for the ridge contact and valley contact. The simulated results show that the transparent electrode wire can be applied for the fingerprint pixel sensor array.
Opus: an overlay peer utility service (2003)

Today, an increasing number of important network services, such as content distribution, replicated services, and storage systems, are deploying overlays across multiple Internet sites to deliver better performance, reliability and adaptability. Currently however, such network services must individually reimplement substantially similar functionality. For example, applications must configure the overlay to meet their specific demands for scale, service quality and reliability. Further, they must dynamically map data and functions onto network resources-including servers, storage, and network paths-to adapt to changes in load or network conditions. In this paper, we present Opus, a large-scale overlay utility service that provides a common platform and the necessary abstractions for simultaneously hosting multiple distributed applications. In our utility model, wide-area resource mapping is guided by an application's specification of performance and availability targets. Opus then allocates available nodes to meet the requirements of competing applications based on dynamically changing system characteristics. Specifically, we describe issues and initial results associated with: i) developing a general architecture that enables a broad range of applications to push their functionality across the network, ii) constructing overlays that match both the performance and reliability characteristics of individual applications and scale to thousands of participating nodes, iii) using Service Level Agreements to dynamically allocate utility resources among competing applications, and iv) developing decentralized techniques for tracking global system characteristics through the use of hierarchy, aggregation, and approximation.
User-adaptive information visualization (2013)

Information Visualization systems have traditionally followed a one-size-fits-all model, typically ignoring an individual user's needs, abilities and preferences. However, recent research has indicated that visualization performance could be improved by adapting aspects of the visualization to each individual user. To this end, this paper presents research aimed at supporting the design of novel user-adaptive visualization systems. In particular, we discuss results on using information on user eye gaze patterns while interacting with a given visualization to predict the user's visualization tasks, as well as user cognitive abilities including perceptual speed, visual working memory, and verbal working memory. We show that such predictions are significantly better than a baseline classifier even during the early stages of visualization usage. These findings are discussed in view of designing visualization systems that can adapt to each individual user in real-time.
Laser-induced damage measurements on phase-unifying mirrors for XeF excimer laser cavities (2004)

Mirrors with a graded reflectance profile have been used for many years in unstable cavities for improving the optical quality of the laser output beams. All the variable reflectivity mirrors are realized with multilayer-coatings containing one or more profiled layers inside the stack. They generally exhibit high reflectance in the central area and very low reflectance in the external area. In particular, phase-unifying (PU) mirrors are graded mirrors properly designed in order to obtain a low wave-front distortion in the transmitted laser beam. In this paper, the laser damage resistance properties of a PU mirror designed for XeF excimer lasers (351 nm) have been studied. The laser-induced damage threshold has been measured by a XeF laser on the high and low reflectivity areas. A correlation between the damage threshold values and the standing wave electric field profile, which settles inside the two coating structures during laser irradiation, has been found.
Extracellular voltage profile for reversing the recruitment order of peripheral nerve stimulation: a simulation study (2004)

Electrical stimulation of peripheral nerve activates large-diameter fibers before small ones. A physiological recruitment order, from small to large-diameter axons, is desirable in many applications. Previous studies using computer simulations showed that selective activation of small fibers could be achieved by reshaping the extracellular voltage profile along the nerve using an array of nine electrodes. In this study, several electrode-array configurations were tested in order to minimize the number of contacts. Electrode arrays of 5, 7, 9, and 11 contacts with 0.75 mm contact separation were performed in computer simulations of dog sacral root (S2). Electrode arrays of 5 and 7 contacts recruited 40% of small axons (<10 microm) when recruiting only 10% of larger axons. Effectiveness of 9- and 11-contact arrays decreased with the presence of epineurium and perineurium. The effectiveness of electrode arrays was independent of stimulation pulsewidth. The biphasic-pulse stimulation with the amplitude of the second phase set as low as possible should be used to prevent the excitation of large axons during the second phase and to minimize the electrode corrosion. Arrays of 5 and 7 contacts also decreased the recruitment curve slope to 26% and 51% of the tripolar electrode, respectively. This modeling study predicts that reversing the recruitment order of peripheral nerve stimulation could be achieved by reshaping the extracellular voltage using electrode arrays of 5 or 7 contacts.

Efficient Construction of Local Parametric Reduced Order Models Using Machine Learning Techniques (2015)

Reduced order models are computationally inexpensive approximations that capture the important dynamical characteristics of large, high-fidelity computer models of physical systems. This paper applies machine learning techniques to improve the design of parametric reduced order models. Specifically, machine learning is used to develop feasible regions in the parameter space where the admissible target accuracy is achieved with a predefined reduced order basis, to construct parametric maps, to chose the best two already existing bases for a new parameter configuration from accuracy point of view and to pre-select the optimal dimension of the reduced basis such as to meet the desired accuracy. By combining available information using bases concatenation and interpolation as well as high-fidelity solutions interpolation we are able to build accurate reduced order models associated with new parameter settings. Promising numerical results with a viscous Burgers model illustrate the potential of machine learning approaches to help design better reduced order models.
Cloning and Expression Analysis of Two Cotton (Gossypium Hirsutum L.) Genes Encoding Cell Wall Proline-rich Proteins (2001)

Two cotton (Gossypium hirsutum L.) genes, ghprp1 and ghprp2, encoding cell wall proline-rich proteins (PRPs) have been cloned and characterized. The ghprpl gene has an open reading frame (ORF) that encodes a PRP of 299 amino acids (aa), whereas the ghprp2 gene contains an ORF that codes for a 310-aa PRP. The GhPRP1 has an 80% identity in aa sequence with that of GhPRP2. Like other plant cell wall PRPs, both cotton PRPs have a hydrophobic signal peptide at their N-termini, followed by repeating peptide units. Northern blot analyses showed that the ghprpl gene is predominantly expressed in the fiber during the elongation stage of fiber development. Reverse transcription (RT)-PCR analysis showed that ghprpl is expressed in both fiber and root tissues, whereas ghprp2 is in roots only. The ghprpl gene was shown to be present in the A1, A2, D1 and D5 genomes of Gossypium by PCR amplification, whereas the ghprp2 gene is only present in the A1 and A2 genomes. The ghprpl gene was over-expressed in the yeast Pichia pastoris, and the expressed GhPRP1 protein was used as an antigen to raise polyclonal antibodies (anti-GhPRP1). Western analysis using the anti-GhPRP1 probe detected a major protein band (50 kDa) in 5-31-day postanthesis (DPA) fibers. However, the 50 kDa protein was absent in other cotton tissues.
“Business Day” & the New York <i>Times</i>: New Life for an Old Priority (1990)

Phosphorylation of a Wiscott-Aldrich Syndrome Protein-associated Signal Complex Is Critical in Osteoclast Bone Resorption (2007)

The activities of different kinases have been correlated to the phosphorylation of Wiscott-Aldrich syndrome protein (WASP) by studies in multiple cell systems. The purpose of this study was to elucidate the regulatory mechanisms involved in WASP phosphorylation and the resulting sealing ring formation in osteoclasts. The phosphorylation state of WASP and WASP-interacting proteins was determined in osteoclasts treated with osteopontin or expressing either constitutively active or kinase-defective Src by adenovirus-mediated delivery. In vitro kinase analysis of WASP immunoprecipitates exhibited phosphorylation of c-Src, PYK2, WASP, protein-tyrosine phosphatase (PTP)-PEST, and Pro-Ser-Thr phosphatase-interacting protein (PSTPIP). Phosphorylation of these proteins was increased in osteopontin-treated and constitutively active Src-expressing osteoclasts. Pulldown analysis with glutathione S-transferase-fused proline-rich regions of PTP-PEST revealed coprecipitation of WASP, PYK2, c-Src, and PSTPIP proteins with the N-terminal region (amino acids 294-497) of PTP-PEST. Similarly, interaction of the same signaling proteins, as well as PTP-PEST, was observed with glutathione S-transferase-fused proline-rich regions of WASP. Furthermore, osteopontin stimulation or constitutively active Src expression resulted in serine phosphorylation and inhibition of WASP-associated PTP-PEST. The inhibition of PTP-PEST was accompanied by an increase in tyrosine phosphorylation of WASP and other associated signaling proteins. Experiments with an inhibitor to phosphatase and small interference RNA to PTP-PEST confirmed the involvement of PTP-PEST in sealing ring formation and bone resorption. WASP, which is identified in the sealing ring of resorbing osteoclasts, also demonstrates colocalization with c-Src, PYK2, PSTPIP, and PTP-PEST in immunostaining analyses. Our findings suggest that both tyrosine kinase(s) and the tyrosine phosphatase PTP-PEST coordinate the formation of the sealing ring and thus the bone-resorbing function of osteoclasts.
