3D reconstruction by polarimetric imaging method based on perspective model (2009)

Classical 3D inspection systems require users to coat transparent objects before measurement. Experimental techniques via non contact measurement, suggested in literature, do not treat inter reflections. The aim of our work is to develop a non contact 3D measurement system for transparent objects by using a polarimetric imaging method in far infrared range. The classical approach relies on the use of orthographic model generated by a telecentric lens in practical setup. However telecentric lenses working in far infrared range are not available. Therefore, we have to adapt pinhole model corresponding to non-telecentric lenses for shape from polarization. In this paper we introduce a 3D reconstruction method to exploit polarimetric imaging with perspective model. We also propose two mathematical approaches in order to reduce reconstruction error: data analysis method to better estimate Stokes parameters and a validation method after Stokes parameters estimation. These techniques are applicable irrespective of the nature of the selected model and any linear system resolution.
Myosin Sequestration Regulates Sarcomere Function, Cardiomyocyte Energetics, and Metabolism, Informing the Pathogenesis of Hypertrophic Cardiomyopathy (2020)

Myosin conformations establish work-energy equipoise that is essential for life-long cellular homeostasis and heart function. Destabilization of myosin energy-conserving states promotes contractile abnormalities, morphological and metabolic remodeling, and adverse clinical outcomes in patients with HCM. Therapeutic restabilization corrects cellular contractile and metabolic phenotypes and may limit these adverse clinical outcomes in patients with HCM.
Expression and Function of CD300 in NK Cells (2010)

The killing activity of NK cells is regulated by signals derived from inhibitory and activating NK cell receptors, including the CD300 family of proteins. CD300a was reported to be expressed on all NK cells and to deliver an inhibitory signal upon binding to a yet unknown ligand/s. The CD300a protein contains four ITIMs and is highly homologous to CD300c. Little is known about the function and distribution of these two receptors and the identity of their ligand/s. In this article, we show that CD300a is indeed an inhibitory receptor expressed by human NK cells, but surprisingly, we show that not all NK clones are inhibited in a CD300a-dependent manner. We demonstrate, using a panel of 13 new anti-CD300a and CD300c Abs that we generated, that CD300a and CD300c are indistinguishable on the surface of NK cells. Using mutational-analysis survey, we show that tyrosine 267 located in the third ITIM motif of the CD300a protein is important for the inhibitory function of CD300a.

Bicuspid aortic valve fusion length correlates with maximum aortic diameter and heamodynamic abnormalities: a 4D flow CMR study (2021)

Abstract Funding Acknowledgements Type of funding sources: Public grant(s) – National budget only. Main funding source(s): Guala A. received funding from the Spanish Ministry of Science, Innovation and Universities. Background Bicuspid aortic valve (BAV), a congenital heart defect, is associated with ascending aorta dilation, possibly via alteration of aortic blood flow [1]. In BAV abnormal flow condition have been associated with aortic extracellular matrix dysregulation and elastic fiber degeneration [2]. Current morphological classification of BAV patients with aortic valve with a single fusion between two adjacent leaflets does not allow for risk stratification. Purpose This research work tested whether the extent of fusion between leaflets is related to AAo diameter and flow alterations. Methods Ninety BAV patients free from moderate and severe aortic valve disease and with no previous aortic or aortic valve surgery or replacement were prospectively enrolled. A comprehensive magnetic resonance protocol comprised a stack of double-oblique 2D balanced steady-state free-precession (bSSFP) cine CMR of the aortic valve, which was used to measure the length of the fusion between leaflets, a cine CMR at the level of the pulmonary bifurcation to assess aortic diameter and 4D flow MRI sequence to assess flow characteristics and regional stiffness [3]. Jet angle and flow radial displacement, quantifying the extent of flow eccentricity, and systolic flow reversal ratio (SFRR), assessing the relative amount of backward flow during systole, were computed at 8 equidistant planes in the ascending aorta and 4 equidistant planes in the aortic arch [4]. A two-tailed p-value &amp;lt; 0.05 was considered statistically significant. Results The length of leaflet fusion varied widely (median 7.7 mm, inter-quartile range [5.5; 10.2]), Table 1). In bivariate analysis, fusion length was also associated to ascending aortic diameter (R = 0.391, p &amp;lt; 0.001), age (R = 0.313, p = 0.005) and body surface area (R = 0.396, p &amp;lt; 0.001). It was also positively related to flow abnormalities: like displacement in the proximal and distal ascending aorta, jet angle in the mid ascending aorta, and SFRR in the ascending aorta and the aortic arch (see Figure 1). The association between fusion length and ascending aorta diameter persisted in multivariate analysis after correction for age (p = 0.006). Conclusions Bicuspid aortic valve fusion extent varies greatly and it is associated with aortic diameter, possibly through flow alterations. Prospective longitudinal studies are needed to establish whether fusion length may allow for risk stratification in bicuspid aortic valve patients.
Creating effective online modules using the cognitive theory of multimedia learning (2021)

In response to the COVID-19 pandemic and associated shutdowns, many universities were forced to pivot to online learning in the spring of 2020. Although abrupt, this pivot creates opportunities for both learners and instructors. This article provides practical advice to educators and instructional designers regarding how to create effective online learning modules using principles derived from the Cognitive Theory of Multimedia Learning. Specifically, we discuss how instructors can utilize advance organizers, concise narrated animations, segmenting, interpolated questions, and learner control to facilitate learning.
Tapered double cantilever beam fracture tests of phenolic-wood adhesive joints. Part II. Effects of surface roughness, the nature of surface roughness, and surface aging on joint fracture energy. (1980)

Tapered double cantilever beam specimens were used to test the effect of surface roughness, the nature of surface roughness, and surface aging on the fracture energy of phenolic-wood adhesive joints. The fracture energy and the failure characteristics of the joints were found to depend not only on the surface roughness but also on the method of surface preparation. The fracture energy increased monotonically with surface roughness for specimens derived from hand-sanded surfaces but exhibited a minimum for specimens obtained from machine-sanded surfaces. Generally, joints from hand-sanded surfaces had higher fracture energies than those derived from the machine-sanded surfaces. Within the joints derived from the machine-sanded surfaces, those sanded perpendicular to the direction of crack growth had higher fracture energies than those sanded parallel to the direction of crack growth. Aging surfaces prior to bonding significantly decreased adhesive joint strength. Notwithstanding the differences in roughness, microscopic examination revealed little difference in the appearance of the sanded surfaces. Adhesive did not penetrate hand-sanded surfaces to any appreciable extent, but did deeply penetrate both the vessel and fiber lumens on the machine-sanded surfaces. Microscopic examination of the fractured surfaces did reveal significant differences that related to the fracture toughness of the bond.

Islanded operation of renewables dominated MV microgrid with highly unbalanced loads (2016)

High integration of renewables in the distribution system provides many advantages that are not yet fully exploited. One of these is the possibility of these environmental friendly resources supplying an islanded microgrid without the need to dispatch fossil fuel-based generators to back up the grid. There are some challenges however, of which the three-phase power imbalances are addressed in this paper. An active network management (ANM) method that splits the grid into resilient zones along with a simple and compact series controller is proposed to allow stable islanded operation. It has been shown using this ANM solution that the phase loads within a resilient zone are supplied with unbalanced power whilst the renewables have continued to supply balanced three-phase power to the microgrid. The proposed solution is considered as a compact, cost effective, retrofit option that allows full utilisation of renewables and enhanced supply continuity and quality to customers.
Fabrication of Complex 3D Fluidic Networks via Modularized Stereolithography (2020)

Stereolithography (SL) 3D printer has been used to fabricate microfluidic channels albeit with limitations in the attainable channel geometries. In the article, number 1901109 by Michinao Hashimoto and co-workers, the fabrication of complex networks of microchannels is enabled by the modularization of fluidic networks into printable elements. 2D and 3D networks of microchannels with high complexity (i.e., multiple branching networks) and small cross-sectional dimensions (w = 75 μm and h = 100 μm) are readily achieved.
High‐Starch and High‐β‐Glucan Barley Fractions Milled with Experimental Mills (2005)

ABSTRACT This study focused on the performance of two hulless barley cultivars (Doyce and Merlin) and one commercial husked (hulled) sample using experimental milling. The purpose was to use experimental milling as a preliminary indicator of the milled streams with potential use for fuel ethanol production and fractions that could be used in food products. Experimental mills designed for flour production evaluation from wheat were Chopin CD1 Auto, Quadrumat Sr, Buhler, and an experimental Ross roller mill walking flow. Results indicate that the shorts had the highest levels of β‐glucan from all the mills. However, the β‐glucan content in the break flours was highest with the roller mill walking flow and the Chopin CD1 for the hulless cultivars. The lowest β‐glucan content in the break flour was found with the Buhler for Doyce. Break flour and, to a slightly lesser extent, reduction flour from all cultivars tested on all mills contained the highest starch content (up to 83%) and are therefore most appropriate for use as feedstock for fuel ethanol production. Conversely, bran and shorts from all cultivars and mills were lowest in starch (as low as 25%), making them ideal as low‐starch food ingredients.
Stiffness Effects in Rocker-Soled Shoes: Biomechanical Implications (2017)

Rocker-soled shoes provide a way to reduce the possible concentration of stress, as well as change movement patterns, during gait. This study attempts to examine how plantar force and spatio-temporal variables are affected by two rocker designs, one with softer and one with denser sole materials, by comparing them with the barefoot condition and with flat-soled shoes. Eleven subjects' gait parameters during walking and jogging were recorded. Our results showed that compared with barefoot walking, plantar forces were higher for flat shoes while lower for both types of rocker shoes, the softer-material rocker being the lowest. The plantar force of flat shoes is greater than the vertical ground reaction force, while that of both rocker shoes is much less, 13.87-30.55% body weight. However, as locomotion speed increased to jogging, for all shoe types, except at the second peak plantar force of the denser sole material rocker shoes, plantar forces were greater than for bare feet. More interestingly, because the transmission of force was faster while jogging, greater plantar force was seen in the rocker-soled shoes with softer material than with denser material; results for higher-speed shock absorption in rocker-soled shoes with softer material were thus not as good. In general, the rolling phenomena along the bottom surface of the rocker shoes, as well as an increase in the duration of simultaneous curve rolling and ankle rotation, could contribute to the reduction of plantar force for both rocker designs. The possible mechanism is the conversion of vertical kinetic energy into rotational kinetic energy. To conclude, since plantar force is related to foot-ground interface and deceleration methods, rocker-design shoes could achieve desired plantar force reduction through certain rolling phenomena, shoe-sole stiffness levels, and locomotion speeds.
<i>H</i><sub>∞</sub> Control Approach to Reduction of Energy Capacity of Energy Storage Systems (2017)

This letter addresses reduction of the energy capacity of energy storage systems (ESSs) using H∞ control theory. The ESSs have been widely used for smoothing fluctuations of wind generator outputs. We propose a direct and efficient method to design controllers that achieve the minimization considering the trade-off between the energy capacity of the ESSs and frequency variation in power systems.
Learning to Communicate: Channel Auto-encoders, Domain Specific\n Regularizers, and Attention (2016)

We address the problem of learning efficient and adaptive ways to communicate\nbinary information over an impaired channel. We treat the problem as\nreconstruction optimization through impairment layers in a channel autoencoder\nand introduce several new domain-specific regularizing layers to emulate common\nchannel impairments. We also apply a radio transformer network based attention\nmodel on the input of the decoder to help recover canonical signal\nrepresentations. We demonstrate some promising initial capacity results from\nthis architecture and address several remaining challenges before such a system\ncould become practical.\n
Activation of the Aryl-Hydrocarbon Receptor Inhibits Invasive and Metastatic Features of Human Breast Cancer Cells and Promotes Breast Cancer Cell Differentiation (2010)

ABSTRACT The current statistics associated with breast cancer continue to show a relatively high recurrence rate together with a poor survival for aggressive metastatic disease. These findings reflect, in part, the pharmaceutical intractability of processes involved in the metastatic process and highlight the need to identify additional drug targets for the treatment of late-stage disease. In the current study, we report that ligand activation of the aryl-hydrocarbon receptor (AhR) inhibits multiple aspects of the metastatic process in a panel of breast cancer cell lines that represent the major breast cancer subtypes. Specifically, it was observed that treatment with exogenous AhR agonists significantly inhibited cell invasiveness and motility in the Boyden chamber assay and inhibited colony formation in soft agar regardless of estrogen receptor (ER), progesterone receptor, or human epidermal growth factor receptor 2 status. Knockdown of the AhR using small interfering RNA duplexes demonstrated that the inhibition of invasiveness was receptor dependent and that endogenous receptor activity was protective in each cell type examined. The inhibition of invasiveness and anchorage-independent growth correlated with the ability of exogenous AhR agonists to promote differentiation. Finally, exogenous AhR agonists were able to promote differentiation in a putative mammary cancer stem cell line. Cumulatively, these results suggest that the AhR plays an important role in mammary epithelial differentiation and, as such, represent a promising therapeutic target for a range of phenotypically distinct human breast cancers.
Serotonin signaling is associated with lower amyloid-β levels and plaques in transgenic mice and humans (2011)

Aggregation of amyloid-β (Aβ) as toxic oligomers and amyloid plaques within the brain appears to be the pathogenic event that initiates Alzheimer's disease (AD) lesions. One therapeutic strategy has been to reduce Aβ levels to limit its accumulation. Activation of certain neurotransmitter receptors can regulate Aβ metabolism. We assessed the ability of serotonin signaling to alter brain Aβ levels and plaques in a mouse model of AD and in humans. In mice, brain interstitial fluid (ISF) Aβ levels were decreased by 25% following administration of several selective serotonin reuptake inhibitor (SSRI) antidepressant drugs. Similarly, direct infusion of serotonin into the hippocampus reduced ISF Aβ levels. Serotonin-dependent reductions in Aβ were reversed if mice were pretreated with inhibitors of the extracellular regulated kinase (ERK) signaling cascade. Chronic treatment with an SSRI, citalopram, caused a 50% reduction in brain plaque load in mice. To test whether serotonin signaling could impact Aβ plaques in humans, we retrospectively compared brain amyloid load in cognitively normal elderly participants who were exposed to antidepressant drugs within the past 5 y to participants who were not. Antidepressant-treated participants had significantly less amyloid load as quantified by positron emission tomography (PET) imaging with Pittsburgh Compound B (PIB). Cumulative time of antidepressant use within the 5-y period preceding the scan correlated with less plaque load. These data suggest that serotonin signaling was associated with less Aβ accumulation in cognitively normal individuals.
An analysis of borrowing policies for escrow transactions in a replicated data environment (2002)

Three issues in the context of escrow-based methods, are addressed. It is shown that full serializability can be guaranteed for escrow transactions by means of repeat semantics, that is, a transaction which fails is rerun in a special mode. The author describes a crash recovery protocol consistent with the concurrency control scheme used. An analysis is made, by means of a simulation model, of several different borrowing policies for escrow transactions and the best one is identified.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Materialized View Selection for Data Warehouse Design (2009)

A Data Warehouse (DW) is a repository of information retrieved from multiple, possibly heterogeneous, autonomous, distributed databases and other information sources for the purpose of complex querying, analysis and decision support. Data in the DW are selectively collected from the sources, processed in order to resolve inconsistencies, and integrated in advance (at design time) before data loading. DW data are usually organized multidimensionally to support On-Line Analytical Processing (OLAP). A DW can be abstractly seen as a set of materialized views defined over the source relations. During the initial design of a DW, the DW designer faces the problem of deciding which views to materialize in the DW. This problem has been addressed in the literature for different classes of queries and views and with different design goals.
Interplay of strain and superlattice ordering onGaInP2quantum-well valence-subband structure (1995)

Spontaneous ${\mathrm{CuPt}}_{\mathit{B}}$-type ordering along 〈111〉 can reduce the crystal symmetry in ${\mathrm{Ga}}_{1\mathrm{\ensuremath{-}}\mathit{x}}$${\mathrm{In}}_{\mathit{x}}$P, splitting the valence-band maximum and introducing optical anisotropy in the interband transition-matrix elements. The growth of lattice-mismatched layers also reduces the symmetry. We present a simple model to describe the combined influence of strain and ordering on the valence-band maximum. We calculate that the valence-subband dispersion and optical-matrix elements are strongly anisotropic over a significant energy range in ${\mathrm{Ga}}_{1\mathrm{\ensuremath{-}}\mathit{x}}$${\mathrm{In}}_{\mathit{x}}$P quantum wells with coexistent epitaxial strain and [1\ifmmode\bar\else\textasciimacron\fi{}11] chemical ordering, using the simple model to explain the observed results. Comparison with disordered, unstrained quantum wells indicates that a combination of chemical ordering and strain may lead to significantly improved gain characteristics in high-quality ${\mathrm{Ga}}_{1\mathrm{\ensuremath{-}}\mathit{x}}$${\mathrm{In}}_{\mathit{x}}$P layers.
Demonstration of image transmission through fibers by optical phase conjugation (1982)

We have demonstrated image transmission through a multimode fiber by using optical phase conjugation. By using the wave-front reversal properties of degenerate four-wave mixing, we have compensated for the degradation of the image that is due to modal dispersion in a fiber.
Face recognition using multiple recognizers (2005)

In this paper we have presented a fusion of three face recognizers, LFA, LBA and KDDA, which combines the three confidence measure factors (CMFs) using a RBF neural network. This strategy is used to increase the accuracy of the face recognition system. The recognizer is tested on AT&T-ORL, AR and IITK face database and the results are found to be more than 95%.
Confocal micro-PIV measurements of three-dimensional profiles of cell suspension flow in a square microchannel (2006)

A detailed measurement of the blood flow velocity profile in microchannels in vitro is fundamental to better understand the biomechanics of microcirculation. Therefore it is very important to determine the influence of suspended blood cells on the flow behaviour with high accuracy and spatial resolution. We measured the flow of blood cells suspended in a physiological fluid within a square microchannel using a confocal particle image velocimetry (PIV) system and compared it to pure water. This emerging technology combines a conventional PIV system with a spinning confocal microscope and has the ability to obtain high-resolution images and three-dimensional (3D) optical section velocity measurements. The good agreement obtained between the measured and estimated results suggests that macroscale flow theory can be used to predict the flow behaviour of a homogeneous fluid within a 100 µm square microchannel. Our results also demonstrated the potential of the confocal system for generating 3D profiles and consequently obtaining detailed information on microscale effects in microchannels using both homogeneous and non-homogeneous fluids, such as a suspension of blood cells. Furthermore, the results obtained from our confocal micro-PIV system show the ability of this system to measure velocities up to 0.52 mm s−1 in a blood cell suspension fluid.
