A FPGA Accelerator for Real-Time 3D Non-rigid Registration Using Tree Reweighted Message Passing and Dynamic Markov Random Field Generation (2018)

Non-rigid 3D registration is a technique for matching 3D scans of a scene involving deformable objects. Augmented reality, gesture recognition, medical imaging, and many other computer vision and graphics applications require real-time registration to model deformable or articulated objects. Unfortunately, non-rigid registration is a computationally intensive problem that requires careful optimization to maximize throughput and latency. We present a FPGA+CPU accelerator for real-time non-rigid 3D registration based on Tree Reweighted Message Passing (TRW-S). We overcome memory bound issues and scheduling limitations of conventional TRW-S by dynamically generating the Markov Random Fields. This, along with a bevy of other architectural optimizations, allows us to almost saturate 1024 multipliers in a Arria 10 at 100MHz. We achieve a 600x speed up over baseline TRW-S and our registration architecture has up to 81x energy reduction over a software implementation of our algorithm. We demonstrate the performance of our system by performing real-time (20 scan per second) registration on a complicated surgical scene.
Thermosensitivity of N-isopropylacrylamide hydrogels cross-linked with degradable cross-linker (2008)

Thermosensitive N-isopropylacrylamide (NIPA)-based hydrogels have been prepared using a biodegradable pseudo-peptide (DMTLT, a tri-molecular adduct of tyrosine, lysine, tyrosine) as cross-linker. This new cross-linker provides a similar cross-linking efficiency as N,N' methylenbisacrylamide (BIS) (a standard biostable cross-linker) used as reference. The amount of DMTLT has shown to modulate, in addition to the cross-linking density, the transition temperature (the higher the amount of DMTLT, the lower the transition temperature), as well as the morphology and the whole aqueous behaviour. The incorporation of hydrophilic N,N'-dimethylacrylamide (DMA) increases the transition temperature, as expected. Finally, the matrices have exhibited in aqueous media a well-defined pulsatile behaviour in swelling and release of benzoic acid and dextran as models of ionisable molecules and non-ionisable macromolecules.
C1q Governs Deposition of Circulating Immune Complexes and Leukocyte Fcγ Receptors Mediate Subsequent Neutrophil Recruitment (2004)

Inflammation induced by circulating immunoglobulin G-immune complexes (ICs) characterizes many immune-mediated diseases. In this work, the molecular requirements for the deposition of circulating ICs and subsequent acute leukocyte recruitment in mice were elucidated. We show that after intravenous injection, preformed soluble ICs are rapidly deposited in the postcapillary venules of the cremaster microcirculation, secondary to increased vascular permeability. This deposition is dependent on complement C1q. IC deposition is associated with leukocyte recruitment. Leukocyte rolling, which is mediated by P-selectin in the exteriorized cremaster muscle, is not further increased in response to ICs. In contrast, leukocyte rolling velocity is significantly decreased and leukocyte adhesion is significantly increased in the presence of ICs. The IC-mediated slow leukocyte rolling velocity and subsequent adhesion and emigration are dependent on Fcgamma receptors (FcgammaRs), particularly FcgammaRIII, with complement C3 and C5 having no detectable role. These studies suggest a regulatory mechanism of IC deposition and leukocyte trafficking in IC-mediated inflammation requiring C1q and FcgammaRs in sequential, noninteracting roles.

Ultrasonic Radiation Field of a Focusing Spherical Source at Finite Amplitudes (1969)

A PZT-4 ceramic spherical cap with a radius of curvature of 30 cm has been used to produce a finite-amplitude ultrasonic field in water at a frequency of 2.3 MHz. The field has been observed by a nonresonant probe with an active face of 18 in. diam. The fundamental, second, third, and fourth harmonics have been studied both along the axis of the beam and transverse to the axis. The axial values are compared with various theoretical analyses.
Expression of the short fimbriae of<i>Porphyromonas gingivalis</i>is regulated in oral bacterial consortia (2006)

The Mfa1 protein of Porphyromonas gingivalis is the structural subunit of the short fimbriae and mediates coadhesion between P. gingivalis and Streptococcus gordonii. We utilized a promoter-lacZ reporter construct to examine the regulation of mfa1 expression in consortia with common oral plaque bacteria. Promoter activity of mfa1 was inhibited by S. gordonii, Streptococcus sanguinis and Streptococcus mitis. In contrast, Streptococcus mutans, Streptococcus cristatus, Actinomyces naeslundii, Actinobacillus actinomycetemcomitans and Fusobacterium nucleatum did not affect mfa1 expression. Expression of SspA/B, the streptococcal receptor for Mfa1, was not required for regulation of mfa1 promoter activity. Proteinaceous molecule(s) in oral streptococci may be responsible for regulation of Mfa1 expression. Porphyromonas gingivalis is capable of detecting heterologous organisms, and responds to selected organisms by specific gene regulation.
Tsunami Inundation Prediction (1977)

This paper concerns the run-up and inundation characteristics of tsunami surges. The forces and moments produced by the waves are not discussed, however, the proposed technique does provide the necessary information for their determination. The method relies on the knowledge of the wave elevation at the coast (as determined from historical data or other means) and an estimation of the bed roughness. The considerations and calculations involved in determining these parameters are discussed in detail. Twenty-four observed run-ups on the island of Hawaii in the case of the 1946 Aleutian tsunami, and 18 run-ups on the island of Maui for the Chilean 1960 tsunami are used to illustrate the technique. Methods are also presented to predict the shoreline heights and extent of inundation of tsunami surges where historical data is not available.
Coupling enhancement between monopole-type resonators using metamaterial cavity (2012)

This work presents the strong coupling of monopole-type resonators using a metamaterial cavity with artificial magnetic conductor (AMC) surfaces and metal planes. The AMC surface is constructed by an array of metal patches on a double-layered dielectric substrate backed by a metallic plane, and its reflection phase with respect to the angle and the polarization of obliquely incident plane waves are characterized by the transmission-line model. The measured transmission power is −2 dB when the resonator spacing is 0.4λ. This demonstrates that the power transfer is enhanced significantly by metamaterial cavity compared to the metal cavity and free space.
Respiratory system, lung, and chest wall impedances in anesthetized dogs (1984)

We measured impedances of the respiratory system (Zrs) and lung (ZL) in anesthetized and paralyzed dogs at frequencies between 4 and 64 Hz. Zrs was measured at functional residual capacity (FRC) and with mean transpulmonary pressures (Ptp) of 12 and 30 cmH2O; ZL was measured with the chest wall open at FRC and Ptp = 12 cmH2O. From these data we derived chest wall impedances at FRC and 12 cmH2O. Effective resistances of the respiratory system, lung, and chest wall were all frequency dependent. At frequencies below 22 Hz frequency dependence of respiratory system resistance was due to the frequency dependence of the chest wall, whereas at higher frequencies it was due to frequency dependence of the lung. Analysis of the impedance data between 4 and 32 Hz provided estimates of resistance, inertance, and compliance of the lung, chest wall, and respiratory system. At FRC, 41% of the respiratory system resistance was due to the lung and 59% was associated with the chest wall. Nearly all of the respiratory inertance (98%) was due to the lung. Lung compliance was approximately twice that of the chest wall, the former accounting for approximately one-third of respiratory elasticity. As lung volume was increased, respiratory resistance and compliance decreased; inertance also decreased, although this change was not significant.
Unc93B1 biases Toll-like receptor responses to nucleic acid in dendritic cells toward DNA- but against RNA-sensing (2009)

Toll-like receptors (TLRs) 3, 7, and 9 recognize microbial nucleic acids in endolysosomes and initiate innate and adaptive immune responses. TLR7/9 in dendritic cells (DCs) also respond to self-derived RNA/DNA, respectively, and drive autoantibody production. Remarkably, TLR7 and 9 appear to have mutually opposing, pathogenic or protective, impacts on lupus nephritis in MRL/lpr mice. Little is known, however, about the contrasting relationship between TLR7 and 9. We show that TLR7 and 9 are inversely linked by Unc93B1, a multiple membrane-spanning endoplasmic reticulum (ER) protein. Complementation cloning with a TLR7-unresponsive but TLR9-responsive cell line revealed that amino acid D34 in Unc93B1 repressed TLR7-mediated responses. D34A mutation rendered Unc93B1-deficient DCs hyperresponsive to TLR7 ligand but hyporesponsive to TLR9 ligand, with TLR3 responses unaltered. Unc93B1 associates with and delivers TLR7/9 from the ER to endolysosomes for ligand recognition. The D34A mutation up-regulates Unc93B1 association with endogenous TLR7 in DCs, whereas Unc93B1 association with TLR9 was down-regulated by the D34A mutation. Consistently, the D34A mutation up-regulated ligand-induced trafficking of TLR7 but down-regulated that of TLR9. Collectively, TLR response to nucleic acids in DCs is biased toward DNA-sensing by Unc93B1.
Implementation lessons on the use of innovation in information technology in the developing world. (2013)

Information Technology (IT) innovation and its impact on health care is of particular relevance to the developing world, which spends a fraction of what health systems spend in OECD countries. Given the issues of accessibility, affordability and quality health services in the developing world, IT can play an important role by bringing marginalized communities closer to health care systems. Aga Khan University (AKU) and the eHealth Resource Center (eHRC), which are part of Aga Khan Development Network (AKDN), are active in the developing regions of East Africa, Central Asia and South East Asia and are currently initiating new changes in the use of IT and also the manner in which it is deployed. The eHealth programmes implemented and the lessons learned by AKU and eHRC in achieving its core values of impact, access, relevance, and quality through implementation of these innovations are described. These can be of value to health systems and academic medical centres in the developing world wanting to leverage scarce resources to create meaningful impact using IT.
An Effective Smooth Transition Control Strategy Using Droop-Based Synchronization for Parallel Inverters (2014)

This paper proposes a smooth transition control strategy for voltage-source inverters between stand-alone (SA) and grid-connected (GC) modes of operation. In both GC and SA modes of operation, the inverters use the droop control method to regulate the real power flow without the need of any external communication between them. One of the distributed energy sources working in the microgrid system is designated as a dispatch unit (DU) to facilitate interconnection with utility grid and achieve smooth transition between the modes of operations. During transition modes, this selected unit takes extra responsibility to ensure the continuous power delivery to the load. For smooth transition from GC to SA mode of operation, the DU compensates for the grid current immediately after the grid disconnection, and then, other units pick up this responsibility gradually through their individual droop controllers. The DU also adjusts its output power to synchronize the inverters with the grid during the transition from SA to GC mode. The simulation and experimental results, as well as the stability analysis, are provided to verify the effectiveness of the proposed control technique.

Capillary pericytes in cochlear lateral wall express strong Kir current and electrical coupling suggest its role in K <sup>+</sup> ‐mediated local blood flow regulation (2012)

Microvessels in spiral ligament (SL) and strial vascularis (SV) are densely populated with pericytes (PC) but their functioning mechanisms are not well understood. Using capillary segments isolated from guinea pig cochlear lateral wall and whole‐cell recording techniques, we found the PCs showed a robust inward K + ‐current, which would play a key role in regulation of local blood flow. Results 1) With physiological solutions, the PCs, but not the endothelial cells (EC), showed a Ba 2+ ‐sensitive inward rectification in I/V domain <‐60 mV. [K + ] o 20 mM enhanced the rectification and induced a ~15 mV hyperpolarization. 2) The PCs’ input conductance and capacitance indicated an 18β‐glycyrrhetinic acid‐sensitive electrical coupling. 3) TEA and 4‐AP showed little effect on IV relations. 4) La 3+ and niflumic acid (0.1 mM) slightly reduced I/V slope with a net current reversal potential ~−15 and 0 mV, respectively. 5) Acetylcholine, norepinephrine, nitrendipine and glipizide caused no significant change in I/Vs or membrane potentials in the PCs. We conclude that local physio‐pathological [K + ] o fluctuation can act on Kir and regulates PC's membrane potential and thus its motor tone. By this mechanism and the spreading effect of gap junction coupling, the PCs may sense the level of K + recycling driven by hair cell acoustic transduction thus to adjust the vasotone and lateral wall blood flow. In addition, cholinergic and adrenergic neuro factors may play little role in the microcirculation control at PC level. Supported by NIH grants R01 DC004716 (ZGJ) and DC00105 (ALN).

The association of dimethylsulfoxide and model membranes studied by pulse‐field gradient NMR (2004)

The use of dimethylsulfoxide (DMSO) as a cryoprotectant to reduce cellular injury during freezing is well known, however the intermolecular interactions between this amphiphilic molecule and biological membranes that form the basis of this protection are unknown. DMSO–dipalmitoylphosphatidylcholine (DPPC) vesicle interactions were investigated in pulsed‐field gradient NMR (PFGNMR) experiments and spectra analysis allowed for the determination of self‐diffusion coefficients for each species present. The mole fraction of DMSO associated with the DPPC vesicles was then calculated from the diffusion coefficients: the mole fraction increased from 14% to 42% as the membrane was heated from below to above the main phase transition temperature.
Optimising UF for wastewater treatment through membrane autopsy and failure analysis (2004)

Since start up, an ultrafiltration (UF) plant at a cosmetic products manufacturer's facility has suffered from frequent membrane fibre damage and rapid fouling of the membranes. To find out what was causing these membrane failures and fouling, an independent study was conducted. The study showed that the damage to the membrane fibres was caused by mechanical forces: high local shear forces or vibrations. Dr Ingmar Huisman, Nalco Europe BV presents the findings of this study.
Investigation into Methods to Improve Ion Source Life for Germanium Implantation (2011)

Germanium tetrafluoride has long been the standard dopant gas of choice for germanium implantation processes. While this material maintains several positive attributes (e.g., it is a nonflammable gas that is easily delivered to an ion source), its use can result in extremely short ion source lifetimes. This is especially the case for the situation when an ion implanter runs solely or predominantly GeF4. Presented here is an examination of various potential solutions to the short source life problem, some of which enable significant improvement.
Vitamin K-dependent carboxylation of pulmonary surfactant-associated proteins. (1987)

Rat type II pneumocytes expressed vitamin K-dependent carboxylase activity that incorporated 14CO2 into microsomal protein precursors of molecular weights similar to those of surfactant-associated proteins (SAP). Compared to carboxylated precursor proteins present in the liver, these molecules appeared to be unique to the lung. Antibodies raised against purified rat surfactant reacted with SAP resolved by NaDodSO4/PAGE and with surfactant-containing lamellar bodies in type II pneumocyte cytoplasm. NaDodSO4/PAGE of microsomal proteins, after carboxylase-catalyzed incorporation of 14CO2, demonstrated radiolabeled, immunoreactive products identical to SAP. The presence of gamma-carboxyglutamic acid in these proteins was confirmed by HPLC analysis of SAP hydrolysates. Furthermore, lung carboxylase activity and SAP matured over similar time courses during fetal lung development. These results show that SAP are carboxylated by type II cells via a vitamin K-dependent pathway analogous to that for hepatic carboxylation of clotting factors. Further analogy to the clotting system suggests that gamma-carboxyglutamic acid residues in SAP polypeptides play a role in Ca2+ binding and thus in the known requirements for both the cation and SAP in the physiological function of pulmonary surfactant.
Land-cover classification using multitemporal ERS-1/2 insar data (2003)

In this study the potential of ERS-1/2 Tandem InSAR data for land-cover classification was investigated at a 2500 km/sup 2/ study area around the Helsinki metropolitan area in Southern Finland. A time-series of 14 ERS-1/2 SAR Tandem image pairs was processed into 28 five-look intensity images, 14 Tandem coherence images and two coherence images with a longer temporal baseline (36 and 246 days). All image data was coregistered and orthorectified into map coordinates using an InSAR DEM. A two-stage hybrid classifier method was employed, where the water-class was classified separately in the first classifier stage, and the remaining classes were classified with an ISODATA classifier. Temporal averaging and Principal Components Transformation (PCT) were used to reduce the number of images fed into ISODATA. Classification accuracy was assessed using high-resolution aerial orthophotos, digital base maps and the Finnish National Forest Inventory (NFI). The overall accuracy for six classes (Field/Open Land, Dense Forest, Sparse Forest, Mixed Urban, Dense Urban, Water) was found to be 90% with kappa coefficient of 0.86. Interferometric coherence carries more land-cover related information than the backscattered intensity. This study confirms that the ERS-1/2 Tandem archives could be exploited for land-cover classification.
Molekulare Verkapselung von Peroxy‐Fettsäuren mit Stärke (1996)

Im Rahmen dieser Arbeit wurden die Stärke-Inklusionskomplexe verschiedener Peroxy-Fettsäuren unter systematischer Variation der Versuchsparameter synthetisiert und hinsichtlich ihrer Eignung als ökologisch unbedenkliche Bleichsysteme für Waschmittel untersucht. Es zeigte sich, daß die Peroxysäuren sich im Komplex recht schnell zersetzen, was wider Erwarten auf eine deutliche Aktivierung der Peroxyfunktion innerhalb der Komplexe hinweist. Untersuchungen der entsprechenden Cyclodextrin-Komplexe bestätigen dies. Die Analyse der Zersetzungsprodukte im Komplex läßt auf einen nicht radikalischen Abbaumechanismus schließen. Eine Verwendung derartiger Einschlußverbindungen als Bleichmittelsysteme für Waschmittel scheint demnach nicht möglich zu sein.
