An Algebraic Local Generalized Eigenvalue in the Overlapping Zone Based Coarse Space : A first introduction (2011)

Coarse spaces are instrumental in obtaining scalability for domain decomposition methods. However, it is known that most popular choices of coarse spaces perform rather weakly in presence of heterogeneities in the coefficients in the partial differential equations, especially for systems. Here, we introduce in a variational setting a new coarse space that is robust even when there are such heterogeneities. We achieve this by solving local generalized eigenvalue problems which isolate the terms responsible for slow convergence. We give a general theoretical result and then some numerical examples on a heterogeneous elasticity problem.

Compensate multiple distortions for speaker recognition systems (2021)

The performance of speaker recognition systems reduces dramatically in severe conditions in the presence of additive noise and/or reverberation. In some cases, there is only one kind of domain mismatch like additive noise or reverberation, but in many cases, there are more than one distortion. Finding a solution for domain adaptation in the presence of different distortions is a challenge. In this paper we investigate the situation in which there is none, one or more of the following distortions: early reverberation, full reverberation, additive noise. We propose two configurations to compensate for these distortions. In the first one a specific denoising autoencoder is used for each distortion. In the second configuration, a denoising autoencoder is used to compensate for all of these distortions simultaneously. Our experiments show that, in the co-existence of noise and reverberation, the second configuration gives better results. For example, with the second configuration we obtained 76.6% relative improvement of EER for utterances longer than 12 seconds. For other situations in the presence of only one distortion, the second configuration gives almost the same results achieved by using a specific model for each distortion.

Comparative Kinetic Studies of Solid Absorber Catalyst (K/MgO) and Solid Desorber Catalyst (HZSM-5)-Aided CO2 Absorption and Desorption from Aqueous Solutions of MEA and Blended Solutions of BEA-AMP and MEA-MDEA (2018)

The kinetic performance of a novel amine solvent blend BEA-AMP was compared with MEA and blended MEA-MDEA in the presence and absence of a solid acid catalyst (HZSM-5) in the desorber column of a bench-scale pilot plant. In addition, a total of seven solid base catalysts were screened using a semibatch reactor to select the one that is most suitable as catalyst for amine-based CO2 absorption. The selected solid base catalyst, K/MgO, was placed in the absorber of the pilot plant. Overall, three absorber-desorber catalytic scenarios were evaluated: blank–blank, blank-HZSM-5, and K/MgO-HZSM-5. For the blank–blank and blank-HZSM-5 scenarios, the novel solvent (4 M BEA-AMP) outperformed 5 M MEA and 7 M MEA-MDEA blend despite BEA-AMP having the lowest molarity. The rates of absorption and desorption for the blank–blank (noncatalytic) scenario for BEA-AMP were 14.8 and 38.4 mol/m3 min, respectively. For the blank-HZSM-5 system, the rates were 18.1 and 45.6 mol/m3 min, respectively. Absorption and desorption rates of 29.7 and 62.4 mol/m3 min, respectively, were obtained for the K/MgO-HZSM-5 system. These results reveal higher rates of absorption and desorption with the inclusion of solid base and solid acid catalysts to the amine-based CO2 capture process. The results show that in the presence of the amine, the electron-rich anion species in K/MgO easily attack the dissolved CO2. This interaction ties the CO2 molecules to the surface of the catalyst, making them readily available for nitrogen atom of the amine in the CO2 absorption process. This process is facilitated because of the large pore size of K/MgO. With the desorber catalyst, easier proton donation by HZSM-5 results in weakening the N–C bond in carbamate, which thereby causes CO2 to break away.
Big data processing using hpc for remote sensing disaster data (2016)

Voluminous data (Multispectral, Hyperspectral) from Variety of sensors (Airborne sensors, space borne sensors) with Velocity (high temporal resolution) when used for decision making to support natural disasters such as earthquakes, floods, oil-spills etc., for near real time accurate responses, is a problem that needs Big Data Analytics. To gain rapid insight from this big data, high performance computing (HPC) with some scalable solution that reduces the execution time are in extreme demand. To serve this real time need, scalable hybrid parallelism approach based on state of art multi-core GPUs and Message Passing Interface (MPI) is explored for analyzing remote sensing disaster data. Spatio-temporal remote sensing data of oil-spill at Gulf of Mexico captured by LANDSAT 7 ETM+ is considered for analysis. The core objective includes performance evaluation of the analysis process across various parallel implementation platforms.
Seismic performance assessment of conventional construction concrete moment-resisting frame buildings in Canada using the FEMA P695 methodology (2022)

National Building Code of Canada (NBC) specifies 45 Seismic Force Resisting Systems to ensure the safety of building structures. Conventional construction concrete moment-resisting frame (CC-CMF) is one of these systems whose seismic response has not been systematically studied in Canada. This paper is an attempt to study the seismic performance of this system using the FEMA P695 methodology. In this regard, different archetype configurations were developed and analyzed through nonlinear static and dynamic analyses. Performance assessment results show that the CSA and NBC requirements for CC-CMF system represent the lower bound of values for seismic force modification factors, and conservatively meet life safety objectives presented in the NBC. Furthermore, different scenarios were considered for identifying ductility-related seismic force modification factor from pushover curves. The effect of height and gravity load levels on seismic force modification factors and collapse margin ratios are also presented by comparing archetypes having different configurations.
Effect of body characteristics on thoracic attenuation of intra-cardiac electrical activity recorded on the surface electrocardiogram (2005)

The objective of this study was to determine the effect of body characteristics on the electrical transfer function of the human thorax. Twenty patients undergoing electrophysiologic study were enrolled. Unipolar stimuli were applied in the right ventricular apical and posterioseptal areas. XYZ surface ECGs and unipolar intra-cardiac electrograms of the pacing impulses were recorded and signal-averaged. The intracardiac-to-surface transfer functions were modeled and compared with body characteristics. Physical dimensions, respiratory measures obtained by spirometry, and age correlated with magnitude intercepts and slopes of the modeled transfer functions in all three directions. The phase transfer functions were correlated with physical dimensions in the Y and Z directions. The effect of body characteristics on the frequency dependency of attenuation and phase has implications on the use of surface ECG and body surface mapping
Figure S2 from Programmed Cell Death Ligand 1 (PD-L1) Signaling Regulates Macrophage Proliferation and Activation (2023)

&lt;p&gt;Supplemental Figure S2. PD-L1 antibody treatment of human macrophages results in phenotypic changes consistent with those seen in murine macrophages. Macrophages were treated with medium only, an irrelevant isotype antibody, or PD-L1 antibody for 6 days, and images were taken of the cells to assess changes in morphology. A non-commercial antibody (A) and Tecentriq (B) were both tested, and changes in confluence (C) were measured every 3 hours for the 6 days with an IncuCyte ZOOM live cell imaging system. An MTT was performed to measure survival of the cells and mean absorbances of MTT substrate were compared statistically with one-way ANOVA and Prism7 software (D). Lastly, surface expression of co-stimulatory molecules (CD40 and CD86) by macrophages treated with the non-commercial antibody (D) and with Tecentriq (F) was compared to control macrophages by flow cytometry using two-way ANOVA and Prism7 software. Statistically significant differences were denoted as P-value * &lt; 0.05, ** &lt; 0.005, *** &lt; 0.0005 and **** &lt; 0.0001, with similar results obtained in 2 independent experiments.&lt;/p&gt;
Converse piezoelectric strain in undoped and Fe-doped AlGaN/GaN heterostructure field effect transistors studied by Raman scattering (2010)

Converse piezoelectric strain in undoped and Fe-doped AlGaN/GaN heterostructure field effect transistors ( HFETs), i.e. the strain induced by applying bias to a transistor, was studied using micro-Raman scattering spectroscopy as a function of applied source-drain voltage for different GaN buffer doping levels and substrate types. By monitoring the phonon frequency shifts and line width of the E(2) and A(1)(LO) phonon modes of GaN, a considerable piezoelectric strain/stress was found in undoped devices, which exhibited a saturation above 40 V bias. This saturation voltage was used to quantify the deep acceptor concentration in the GaN buffer layer. Using experimental Raman data and numerical modelling of the electric field distribution in the device, it was furthermore established that Fe doping causes confinement of the strain/stress to the vicinity of the AlGaN/GaN interface, i.e. near the electron channel, with potential implications for device reliability. It was concluded that varying the structure and doping in the buffer layer has the potential to modify the converse piezoelectric strain and hence affect reliability issues in AlGaN/GaN HFETs.
Picture Segmentation by a Tree Traversal Algorithm (1976)

In the past, picture segmentation has been performed by merging small primitive regions or by recursively splitting the whole picture. This paper combines the two approaches with significant increase in processing speed while maintaining small memory requirements. The data structure is described in detail and examples of implementations are given.
Excitation of a conducting cylindrical surface of large radius of curvature (1962)

Approximate expressions are obtained for the magnetic field induced by slots on conducting circular cylinders of infinite length and of radius large compared to the signal wavelength. The approximations are derived from the formal solution of the cylinder problem and are valid for all distances from the slot. The expression for a short slot dipole, at any orientation, is expressed in terms of the field of the slot on a flat conducting sheet multiplied by a curvature term. The latter is a function of the "ray path" length and radius of curvature, making the results applicable to other convex surfaces. Corresponding expressions for half wavelength axial and transverse slots are also obtained and the results compared with experimental measurements.
Micro-Hydrokinetic Turbine Operating in the Vicinity of a Free Surface: Multiphase Large Eddy Simulations (2019)

Abstract Large Eddy Simulation (LES) turbulence and multiphase Volume of Fluid (VOF) model are employed to predict the spatial and temporal characteristics of the turbulent flow structures near micro-hydrokinetic turbine operating in the proximity of a free surface. The turbine power performance and the free surface dynamics, and its interaction with the turbine are characterized by examining the results of both single-phase and multiphase flow simulations. Simulations are conducted at the turbine’s best efficiency point at a tip speed ratio of 1.86 with the rotation rate of 150 rpm and the free stream water velocity of 2.25 m/s. The multiphase flow simulation is carried out at Froude number of 1.06. The results indicate slight interaction between the deformed free surface and the turbine wake structures. Acceleration in the flow velocity is observed near the free surface due to the physical confinement. The results indicate that turbine power generation is reduced by about 2.0%, and the thrust coefficient is reduced by 1.60%. It is demonstrated that the turbine performance at this Froude number is hardly influenced by the presence of the free surface.
High-resolution x-ray diffraction study of the heavy-fermion compound YbBiPt (2015)

YbBiPt is a heavy-fermion compound possessing significant short-range antiferromagnetic correlations below a temperature of $T^{\textrm{*}}=0.7$ K, fragile antiferromagnetic order below $T_{\rm{N}}=0.4$ K, a Kondo temperature of $T_{\textrm{K}} \approx1$ K, and crystalline-electric-field splitting on the order of $E/k_{\textrm{B}}=1\,\textrm{-}\,10$ K. Whereas the compound has a face-centered-cubic lattice at ambient temperature, certain experimental data, particularly those from studies aimed at determining its crystalline-electric-field scheme, suggest that the lattice distorts at lower temperature. Here, we present results from high-resolution, high-energy x-ray diffraction experiments which show that, within our experimental resolution of $\approx6\,\textrm{-}\,10\times10^{-5}$ Å, no structural phase transition occurs between $T=1.5$ and $50$ K. In combination with results from dilatometry measurements, we further show that the compound's thermal expansion has a minimum at $\approx18$ K and a region of negative thermal expansion for $9

Reduced resource consumption through three generations of Galantamine·HBr synthesis (2013)

In the pharmaceutical industry, there is always a desire to identify better synthesis pathways and technologies. Chemistry can be changed resulting in safer reactions, higher yields, better recyclability, etc. Also new technologies as for e.g. continuous flow reactors can be used allowing better heat transfer and better reaction efficiencies compared to batch reactors. It is these innovations that make green chemistry actually happen. However, according to the principle “you can only manage what you can measure”, also measuring methods are required for the evaluation of the innovative improvements. Many chemistry related measuring methods are available for the evaluation of the greenness, eco-efficiency or even sustainability of new developments. In this article, exergetic life cycle assessment is used on a real case from the pharmaceutical industry (three generations of Galantamine·HBr synthesis) to illustrate the importance of the continuous search for improved chemical processes and technologies and of using measuring methods in order to support, quantitatively, the decision making towards new, greener and more sustainable processes and technologies. From this case, it can be concluded that a reduction in the overall resource consumption can rise up to 41% by optimizing the first generation pathway by new chemistry and by a new technology, i.e. continuous flow reactors.

Zinc-iron, but not zinc-alone supplementation, increased linear growth of stunted infants with low haemoglobin. (2007)

Zinc supplementation has been shown to benefit linear growth. However the effect may depend on whether zinc is the most limiting nutrient. This study aims to investigate the effect of supplementation with zinc-given alone or with iron and vitamin-A in improving infantsf micronutrient status and linear growth. The study was a double-blind-community-intervention study involving 800 infants aged 3-6 months in rural East Lombok, West Nusa Tenggara. Syrup consisting of zinc-alone, Zn (10 mg/d), zinc+iron, Zn+Fe (10 mg/d of each), zinc+iron+vitamin-A, Zn+Fe+vit.A (10 mg/d of each zinc and iron plus 1,000 IU vitamin-A), or placebo were given daily for six months. Outcomes measured were length, weight, and micronutrient status (haemoglobin, se-rum zinc, ferritin and retinol). Zn+Fe and Zn+Fe+vit.A supplementations benefit zinc and iron status of the sub-jects, while Zn-alone supplementation disadvantaged haemoglobin and iron status. The highest increment in vi-tamin A and haemoglobin status was shown in Zn+Fe+vit.A group. An effect on linear growth was observed among initially-stunted subjects in Zn+Fe and Zn+Fe+vit.A groups who grew 1.1-1.5 cm longer than placebo. On the other hand, in the Zn-alone group, mean height-for-age Z-score decreased to a greater extent than placebo. The between-group difference in HAZ among initially-stunted subjects was significant after four months sup-plementation. While the difference was not significant in follow-up after 6 months, the pattern remained the same where means height-for-age Z-score in Zn+Fe+vit.A and Zn+Fe groups were higher than placebo and Zn-alone groups. Given the low haemoglobin/iron status of the subjects, zinc supplementation would have positive effect on growth if the low haemoglobin/iron status is also addressed and corrected.
Data from Inhibitor of Growth 4 Suppresses Cell Spreading and Cell Migration by Interacting with a Novel Binding Partner, Liprin α1 (2023)

&lt;div&gt;Abstract&lt;p&gt;Inhibitor of growth 4 (ING4) is a candidate tumor suppressor that plays a major role in gene regulation, cell cycle control, apoptosis, and angiogenesis. ING4 expression is down-regulated in glioblastoma cells and head and neck squamous cell carcinoma. Here, we identified liprin α1/PPFIA1, a cytoplasmic protein necessary for focal adhesion formation and axon guidance, as a novel interacting protein with ING4. ING4 and liprin α1 colocalized at lamellipodia in the vicinity of vinculin. Overexpressed ING4 suppressed cell spreading and cell migration. In contrast, overexpressed liprin α1 enhanced cell spreading and cell migration. Knockdown of endogenous ING4 with RNA interference induced cell motility, whereas knockdown of endogenous liprin α1 suppressed cell motility. ING4 also suppressed cell motility that was enhanced by liprin α1. However, ING4 did not further suppress cell motility when liprin α1 was suppressed with RNA interference, suggesting a functional and mechanistic interdependence between these proteins. In addition to its nuclear functions, cytoplasmic ING4 interacts with liprin α1 to regulate cell migration and, with its known antiangiogenic function, may prevent invasion and metastasis.

Multi-target tracking with an event-based vision sensor and a partial-update GMPHD filter (2019)

Tracking a large number of small, similar, high-speed/- agility targets is a challenging problem for current tracking systems that make use of traditional visual sensors. Such targets necessitate very high tracker update rates to keep up with meandering and mutually-occluding target paths. Event-based vision sensors may offer a solution to this problem as they report only &#x201C;event-based&#x201D; pixelwise changes in intensity as they occur with a time resolution approaching 1 &#x3BC;s [1], providing data that is much sparser and higher in time-resolution than traditional vision systems. However, this class of sensor presents unique challenges; for example, a single object in the sensor&#x2019;s field of view may produce multiple synchronous or nearly-synchronous events. In addition, performing direct measurement-to-track association for event data on ms to ms timescales introduces problematic computational burdens for scenarios involving large numbers of targets. The work described in this paper is twofold. We first define and apply an event-clustering procedure to raw events to reduce the amount of data passed into the tracker. This transformation from events to event-clusters provides a) discrimination between event-clusters that correspond to true targets and those that do not and b) reduction in tracking computation time. Second, we define and apply a partial-update Gaussian mixture probability hypothesis density (GMPHD) filter [2] for tracking using event-cluster data. We demonstrate increased computational performance over the standard GMPHD filter while achieving comparable tracking performance per the optimal sub-pattern assignment (OSPA) metric [3].
