Rigid Body Structure and Motion From Two-Frame Point-Correspondences Under Perspective Projection (2018)

This paper is concerned with possibility of recovery of motion and structure parameters from multiframes under perspective projection when only points on a rigid body are traced. Free (unrestricted and uncontrolled) pattern of motion between frames is assumed. The major question is how many points and/or how many frames are necessary for the task. It has been shown in an earlier paper {Klopotek:95b} that for orthogonal projection two frames are insufficient for the task. The paper demonstrates that, under perspective projection, that total uncertainty about relative position of focal point versus projection plane makes the recovery of structure and motion from two frames impossible.
Activation of monocytes by interferon-gamma has no effect on the level or affinity of the nicotinamide adenine dinucleotide-phosphate oxidase and on agonist-dependent superoxide formation. (1988)

Human monocytes purified by elutriation were cultured for 3 d in Teflon bags with or without human recombinant interferon-gamma (rIFN gamma). The cells were then collected and used in suspension to determine the rate of stimulus-dependent superoxide or hydrogen peroxide formation as a measure of the NADPH-oxidase. The treatment with IFN gamma increased this rate two- to threefold when phorbol myristate acetate (PMA) was used as the stimulus. By contrast, no IFN gamma-dependent increase in superoxide production was observed when the cells were stimulated with different concentrations of the receptor agonist N-formyl-methionyl-leucyl-phenylalanine (f-Met-Leu-Phe) alone or in combination with another receptor agonist, platelet-activating factor (PAF). At optimum concentrations, f-Met-Leu-Phe elicited rates of superoxide formation that could not be exceeded under other stimulatory conditions including PMA after treatment with IFN gamma. It thus appears that f-Met-Leu-Phe can lead to maximum activation of the NADPH-oxidase, and that this response is not influenced by IFN gamma. Treatment with IFN gamma also failed to affect the affinity of PMA- or f-Met-Leu-Phe-stimulated oxidase for NADPH, the Km values being 30 to 40 microM under all conditions. IFN gamma did not alter the cellular levels of cytochrome b558, as measured by low-temperature spectroscopy, and protein kinase C, as measured by [3H]phorbol dibutyrate binding, and did not appreciably influence the stimulus-dependent increase of cytosolic free calcium. These results indicate that activation of human mononuclear phagocytes by IFN gamma does not affect the level and the kinetic properties of NADPH-oxidase or its activation by receptor agonists. They confirm, however, that IFN gamma enhances the respiratory burst response to PMA.
Tumor rejection antigens of chemically induced sarcomas of inbred mice (cell surface antigens/M, 96,000 glycoprotein/tumor-enhancing activity) (2016)

Chemically induced sarcomas of inbred mice are immunogenic in syngeneic hosts, and preimmunization with tumor cells leads to resistance to subsequent tumor transplants. The tumor rejection antigens (TRAs) that mediate this reaction are highly specific for each tumor; cross-protec- tion between different syngeneic sarcomas is rare. Isolated membrane and cytosol fractions from two antigenically distinct BALB/c sarcomas, Meth A and CMS5, have TRA activity, and biochemical characterization of the active components from the cytosol and plasma membranes of these two tumors identified a glycoprotein of Mr 96,000. Immunization with unfractionated Meth A cytosol frequently leads to tumor enhancement, but the tumor-enhancing activity (TEA) is lost on fractionation and TRA activity becomes demonstrable. As Meth A and CMS5 lack expression of murine leukemia virus (MuLV) antigens or transcripts, MuLV-related antigens cannot be involved in the TEA or TRA activities of these tumors. In contrast to the lack of cross-reactivity between Meth A and CMS5 TRAs in transplantation tests, rabbit antiserum prepared against the Meth A Mr 96,000 antigen reacted with the CMS5 Mr 96,000 antigen. In view of the biochemical and antigenic similarities of Meth A and CMS5 TRAs, we propose that structurally related but distinct Mr 96,000 glycoproteins are expressed in chemi- cally induced sarcomas and that these molecules are respon- sible for the individually specific immunogenicity of these tumors.
Efficient face retrieval using synecdoches (2014)

The number of images and videos available for search on the Internet is in the order of a trillion images, making current brute force search techniques prohibitively inefficient on such large scales. As society continues to increase our desire and ability to search these vast collections of data, improving upon traditional face recognition search techniques becomes an important problem to address. Because face recognition (and other biometric) algorithms are only commercially available as black box systems, any indexing scheme developed to perform efficient search must operate without access to the underlying feature vectors used to measure facial similarity. To address this restriction, we propose a structured search that separates the facial feature space into clusters derived from sets of prototype subjects we refer to as “synecdoches”. After an offline training step, our proposed method assigns each gallery image to a cluster in the face space based on its similarity to a set of synecdoche clusters. In turn, query images are compared to the target gallery images based on the closest synecdoche cluster in sequence. Our results show a minimal drop in accuracy when only considering half of the clusters, thus reducing the search space in half. Additional experiments demonstrate the viability of our proposed approach to improve search efficiency amidst the common restriction of a black box matcher.
New methoxo-, hydroxo- and pyrazolate-bridged platinum(II) complexes. Crystal structure of [NBu4]2[{Pt(C6F5)2}2(µ-OH)(µ-dmpz)](dmpz = 3,5-dimethylpyrazolate) (1992)

The hydroxo complex [{Pt(C6F5)2(µ-OH)}2]2– reacts with azoles (1 : 1 molar ratio) in benzene to give the double bridged complexes [{Pt(C6F5)2}2(µ-OH)(µ-L–L)]2–[L–L = pyrazolate (pz)1, 3,5-dimethyl-pyrazolate (dmpz)2, 3-methylpyrazolate (mpz)3 or indazolate(indz)4]. When the same reaction is carried out in methanol with the reactants in 1 : 2 molar ratio the corresponding di-µ-azolate derivatives [{Pt(C6F5)2(µ-L–L)}2]2–[L–L = pz 5, dmpz 6, mpz 7 or indz 8] are obtained. On treatment of [{Pt(C6F5)2(µ-OH)}2]2– with methanol the di-µ-methoxo complex [{Pt(C6F5)2(µ-OMe)}2]2–9 was obtained. The di-µ-azolate complexes 5–8 can be alternatively prepared by treatment of 9 with the respective azoles (1 : 2 molar ratio) in methanol. Reaction of complex 1 with methanol leads to the formation of [{Pt(C6F5)2}2(µ-OMe)(µ-pz)]2–10. All the complexes have been isolated as the [NBu4]+ salts. Spectroscopic (IR, 1H and 19F NMR) data have been used for structural assignments, and an X-ray structure determination carried out for [NBu4]2[{Pt(C6F5)2}2(µ-OH)(µ-dmpz)] has established the binuclear nature of the anion. The structure was solved and refined to R= 0.057 and R′= 0.089 based on 10 057 observed reflections. The Pt atoms are four-co-ordinated, Pt(1)–O 2.113(7), Pt(1)–N(1) 2.04(1), Pt(1)–C(10) 2.02(1), Pt(1)–C(20) 1.96(2), Pt(2)–O 2.077(9), Pt(2)–N(2) 2.075(9), Pt(2)–C(30) 1.97(2), Pt(2)–C(40) 2.00(1)Å, and show deviations from a square-planar arrangement towards a tetrahedral disposition.
A new treatment protocol using photobiomodulation and muscle/bone/joint recovery techniques having a dramatic effect on a stroke patient's recovery: a new weapon for clinicians (2012)

The subject of this case study is a 29-year-old woman who suffered a brainstem stroke. She remained severely dizzy, had a non-functional left hand secondary to weakness, severe spasticity in the right hand, a right lateral sixth nerve palsy and was unable to ambulate on presentation. The stroke occurred 2 years before presentation. The subject had been treated for 21 months at two different stroke rehabilitation centres before presentation. Our stroke protocol includes photobiomodulation administered with the XR3T-1 device and 'muscle/bone/joint/soft tissue' recovery techniques. The patient was seen once a week for 8 weeks and treatment sessions lasted approximately 60 min. The results were dramatic: after 8 weeks of implementation of our protocol, the patient demonstrated positive change in every area of her deficits as determined by improvements in physical examination findings. The gains achieved at 8 weeks have been maintained to this day and she continues to be treated once every 4 weeks.
Using a Novel Solvent-based Technology to Preserve Low-k Material when Removing Gap Fill Material (2009)

As the technology nodes shrink, device makers are running into barriers with traditional post etch process flows. In the back-end-of-line (BEOL), the porous low-k materials can be damaged by the etch chemistries, the dry ash plasmas and the subsequent cleaning processes. Replacing the dry ash and typical wet cleaning processes with a one step selective solvent-based removal process can work to protect the etched low-k. The solvent-based blend must remove the reactive ion etch (RIE) residues and gap fill material used in the patterning step while preserving the low-κ from further damage. This paper will focus on the removal of films and post etch residues in under 2 minutes with a novel solvent formulation.

Optical Limiting Chromophores. Correlation Effects in Computing Triplet−Triplet Absorption Energies of Organic Molecules (2000)

The computation of molecular triplet−triplet absorption wavelengths for a series of organic chromophores potentially useful in reverse saturable absorption and photodynamic therapy has been systematically investigated using the semi-empirical INDO/S model Hamiltonian. The effect of parameters defining the model and of the level of configuration interaction on the computed triplet absorption have been explored in detail. From eight different models which vary in the INDO/S model Hamiltonian parameters and the level of excited configurations used in the CI, a reliable model that estimates the triplet absorption of organic π-conjugated systems has been deduced. The model that employs Zerner's suggested triplet parameters and uses a MRD-CI level of configuration interaction reproduces the experimentally observed triplet absorption to reasonable accuracy. While this model performs exceptionally well in the case of acenes (fused unsubstituted ring systems) and α,ω-diphenyl polyene systems, it performs somewhat less well for organic molecules substituted with polar functional groups. The total RMS deviation in the computed triplet absorption λmax of 100 organic molecules is 58 nm with a correlation coefficient of 0.85 for the entire set, 56 nm (correlation coefficient = 0.93) in the case of acenes, and 56 nm (correlation coefficient = 0.96) for α,ω-diphenyl polyenes.
Atypical osteomyelitis of the skull base (1989)

Most cases of osteomyelitis of the skull base occur as a result of inadequately treated localized malignant otitis externa. We present four patients with osteomyelitis of the skull base who did not present initially as malignant otitis externa. Increased morbidity may occur when these atypical cases are not promptly recognized and treated.
Mechanisms of platelet aggregation by viridans group streptococci (1987)

The direct aggregation of platelets is thought to be an important event in the pathogenesis of viridans streptococcal endocarditis, but the mechanisms for platelet activation are unknown. We evaluated the processes by which two endocarditis-producing strains of viridans group streptococci activated human platelets in vitro, as measured by platelet cyclooxygenase activity, secretion, and aggregation. Addition of either streptococcal strain to platelets suspended in whole plasma resulted in a mean lag phase of 15.3 min, followed by platelet secretion and brisk aggregation. The lag phase duration was dependent on the platelet donor and appeared to be a function of direct platelet-bacterial interaction. Aggregation was partially inhibited by 20 muM [corrected] indomethacin and blocked completely by 1 mg of apyrase, an extracellular ADP hydrolase, per ml. Neither strain aggregated washed platelets suspended in Tyrode solution alone. However, both strains produced maximal aggregation when the platelet suspension was supplemented with 10% (final concentration) normal plasma. Studies with factor-deficient plasmas demonstrated that exogenous fibrinogen was required for aggregation. One or more additional plasma components were needed, which eluted with a molecular weight of 67,000 to 130,000 on gel permeation chromatography. These cofactors have not been described for other platelet agonists, which suggests that viridans streptococci may aggregate human platelets by a novel mechanism.
CD99+Faslow Ramos cells, representative of early centroblasts, are sensitive to IgM induced apoptosis (45.9) (2011)

Abstract Ramos cell line, derived from human Burkitt’s lymphoma, expresses a centroblastic phenotype in the early stage of B cell development in germinal center. In previous study, CD99 positive cells were scattered throughout the lymph nodes, but most cells in germinal center had low expression of CD99 in immunohistochemical staining. Here, we hypothesize that CD99+Faslow Ramos cells may be representative of early centroblasts and have sensitivity to IgM induced apoptosis. Using B cells from human tonsils, we have evaluated various markers of centroblastic stage. We found that the expression of Fas was low in the early centroblastic stage and gradually increased during differentiation. Ramos cells that have heterogenous expressions of CD99 were subcloned into CD99+ and CD99-. IgM induced apoptosis in CD99+ clones was higher than that of CD99- clones. CD99+ clones showed heterogeneous patterns of Fas expression from low to intermediate levels, while CD99- clones were homogenous in terms of intermediate expression of Fas. CD99+Faslow and CD99-Fashigh clones were subcloned, and the expression of Fas was gradually increased during the long term culture of CD99+Faslow clones. CD99+Faslow clones were the most sensitive cells for IgM induced apoptosis. All of these results indicate that CD99+Faslow cells may be representative of early centroblasts and sensitive to IgM induced apoptosis. we will investigate the molecular mechanism of this apoptotic signaling pathway in the early centroblast.
Small Molecule Active Site Directed Tools for Studying Human Caspases (2015)

Caspases are proteases of clan CD and were described for the first time more than two decades ago. They play critical roles in the control of regulated cell death pathways including apoptosis and inflammation. Due to their involvement in the development of various diseases like cancer, neurodegenerative diseases, or autoimmune disorders, caspases have been intensively investigated as potential drug targets, both in academic and industrial laboratories. This review presents a thorough, deep, and systematic assessment of all technologies developed over the years for the investigation of caspase activity and specificity using substrates and inhibitors, as well as activity based probes, which in recent years have attracted considerable interest due to their usefulness in the investigation of biological functions of this family of enzymes.

Validating timing constraints in multiprocessor and distributed real-time systems (2002)

In multiprocessor and distributed real-time systems, scheduling jobs dynamically on processors is likely to achieve better performance. However, analytical and efficient validation methods to determine whether all the timing constraints are met do not exist for systems using modern dynamic scheduling strategies, and exhaustive simulation and testing are unreliable and expensive. This paper describes several worst-case bounds and efficient algorithms for validating systems in which jobs have arbitrary timing constraints and variable execution times and are scheduled on processors dynamically in a priority-driven manner. The special cases of the validation problem considered here are concerned with independent jobs that are (1) preemptable and migratable, or (2) preemptable and nonmigratable, or (3) nonpreemptable.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Camshift Guided Particle Filter for Visual Tracking (2007)

Particle filter and mean shift are two important methods for tracking object in video sequence, and they are extensively studied by researchers. As their strength complements each other, some effort has been initiated in [1] to combine these two algorithms, on which the advantage of computational efficiency is focused. In this paper, we extend this idea by exploring even more intrinsic relationship between mean shift and particle filter, and propose a new algorithm, CamShift guided particle filter (CAMSGPF). In CAMSGPF, two basic algorithms - CamShift and particle filter - can work cooperatively and benefit from each other, so that the overall performance is improved and some redundancy in algorithms can be removed. Experimental results show that the proposed method can track objects robustly in various environments, and is much faster than the existing methods.
Master equations and quantum trajectories for squeezed wave packets (2022)

The interaction between matter and squeezed light has mostly been treated within the approximation that the field-correlation time is small. Methods for treating squeezed light with more general correlations currently involve explicitly modeling the systems producing the light. We develop a general purpose input-output theory for a particular form of narrowband squeezed light, a squeezed wave-packet mode, that only concerns the statistics of the squeezed field and the shape of the wave packet. This formalism allows us to derive the input-output relations and the master equation. We also consider detecting the scattered field using photon counting and homodyne measurements, which necessitates the derivation of the stochastic master equation. The non-Markovian nature of the field manifests itself in the master equation as a coupled hierarchy of equations. We illustrate these with consequences for the decay and resonance fluorescence of two-level atoms in the presence of such fields.
A Controlled Trial of Homocysteine Lowering and Cognitive Performance (2006)

On the Interference of two Gaussian beams and their ABCD Matrix representation (2009)

Gaussian beam propagation is well described by the q-parameter and the ABCD matrices. A variety of ABCD matrices are available that represent commonly occurring scenarios/components in optics. One important phenomenon that has not been studied in detail is the interference of two optical beams with different q-parameters undergoing interference. In this paper, we describe the effect of interference of two Gaussian beams. We derive an ABCD matrix for the addition of two beams that takes into account both the amplitude and phase difference between two beams. This ABCD matrix will help greatly in determining the propagation of beams inside complex interferometers and finding the solutions for the coupled cavity Eigenmodes.
