1. The Image Deblurring Problem (2006)

You cannot depend on your eyes when your imagination is out of focus. — Mark Twain When we use a camera, we want the recorded image to be a faithful representation of the scene that we see—but every image is more or less blurry. Thus, image deblurring is fundamental in making pictures sharp and useful. A digital image is composed of picture elements called pixels. Each pixel is assigned an intensity, meant to characterize the color of a small rectangular segment of the scene. A small image typically has around 2562 = 65536 pixels while a high-resolution image often has 5 to 10 million pixels. Some blurring always arises in the recording of a digital image, because it is unavoidable that scene information “spills over” to neighboring pixels. For example, the optical system in a camera lens may be out of focus, so that the incoming light is smeared out. The same problem arises, for example, in astronomical imaging where the incoming light in the telescope has been slightly bent by turbulence in the atmosphere. In these and similar situations, the inevitable result is that we record a blurred image. In image deblurring, we seek to recover the original, sharp image by using a mathematical model of the blurring process. The key issue is that some information on the lost details is indeed present in the blurred image—but this information is “hidden” and can only be recovered if we know the details of the blurring process. Unfortunately there is no hope that we can recover the original image exactly! This is due to various unavoidable errors in the recorded image. The most important errors are fluctuations in the recording process and approximation errors when representing the image with a limited number of digits. The influence of this noise puts a limit on the size of the details that we can hope to recover in the reconstructed image, and the limit depends on both the noise and the blurring process.

Topology matching for fully automatic similarity estimation of 3D shapes (2001)

There is a growing need to be able to accurately and efficiently search visual data sets, and in particular, 3D shape data sets. This paper proposes a novel technique, called Topology Matching, in which similarity between polyhedral models is quickly, accurately, and automatically calculated by comparing Multiresolutional Reeb Graphs (MRGs). The MRG thus operates well as a search key for 3D shape data sets. In particular, the MRG represents the skeletal and topological structure of a 3D shape at various levels of resolution. The MRG is constructed using a continuous function on the 3D shape, which may preferably be a function of geodesic distance because this function is invariant to translation and rotation and is also robust against changes in connectivities caused by a mesh simplification or subdivision. The similarity calculation between 3D shapes is processed using a coarse-to-fine strategy while preserving the consistency of the graph structures, which results in establishing a correspondence between the parts of objects. The similarity calculation is fast and efficient because it is not necessary to determine the particular pose of a 3D shape, such as a rotation, in advance. Topology Matching is particularly useful for interactively searching for a 3D object because the results of the search fit human intuition well.
Association of Circulating C-Reactive Protein and Interleukin-6 with Longevity into the 80s and 90s: The Rancho Bernardo Study (2010)

Microbubble powered actuator (2002)

A micromechanical, bubble-powered actuator is presented which can produce mechanical displacements as large as 140 mu m of a polysilicon actuator plate in a direction perpendicular to the substrate with as little as 8.4 mA input current. This device has been designed, fabricated, and successfully tested to have controllable displacement in a nonconducting liquid (Fluorinert FC43). The principle of actuation is the local heating of a polysilicon line resistor (immersed in liquid) in order to create a single, controllable microbubble that expands and lifts the actuator plate formed at the end of a microcantilever beam. The displacement of this actuator is stable and is controllable by adjusting the input current, which changes the bubble size and, subsequently, changes the actuator plate displacement. Linear beam theory has been used to calculate the displacement of the actuator plate and a simplified model has been used to explain the thermal behavior of the bubble.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Recklessness as a hallmark of aggressive cancer (2007)

Cancer recurrence after surgical treatment is a major concern for patients and doctors. Understanding what makes tumors prone to recurrence would be an important step toward its prevention. Accumulating evidence indicates that the level of membrane-associated protease regulator reversion-inducing cysteine-rich protein with Kazal motifs (RECK) expressed in tumor tissue is a good prognostic indicator in several common cancers. Certain members of the matrix metalloproteinase family are often upregulated in advanced cancers and are known to play important roles in tumor angiogenesis, invasion and metastasis. RECK negatively regulates several matrix metalloproteinases. Therefore, RECK itself may well be considered a promising tool or target molecule to be activated in cancer therapy. Here we review the recent advances in RECK research and discuss some of the important issues to be addressed in future studies.
VON WISPR Family Processors: Volume 1. (1997)

Abstract : Fluctuation-based signal processing is a new approach to signal processing. It focuses on the situation in which the signals of interest fluctuate less than signals that are not of interest (clutter) and the background noise they are embedded in. Processors utilizing those fluctuations such as the von WISPR Family Processors discussed herein, are methods or algorithms that preferentially attenuate the fluctuating signals and noise as their fluctuation levels increase. Both amplitude and phase fluctuations can be exploited, the latter requiring novel approaches to coherent processing. The net effects can be significant enhancements in the characteristics, attributes, or products of the signal processor. Some examples include enhancements in signal-to-noise ratio, clutter reduction or elimination, spatial and spectral resolution, and minimum detectable level. Several processors that provide such enhancements are presented and discussed using measured and simulated data. In many cases, the results are independent of the spatial aperture of the measurement apparatus (sensor or array) and the spectral resolution (frequency binwidth) of the spectrum analyzer. The implication is that exploiting fluctuations is a means whereby the signal processor can tap into an additional independent source of gain. The results presented herein provide both qualitative and quantitative measures of the additional gains that can be achieved by exploiting the fluctuations in signal and noise. Although most of the examples presented are for underwater acoustic data, the generality of fluctuation-based processing is demonstrated for other types of data as well.
Combinatorial protein therapy of angiogenic and arteriogenic factors remarkably improves collaterogenesis and cardiac function in pigs (2007)

Establishment of functional and stable collaterals in the ischemic myocardium is crucial to restoring cardiac function after myocardial infarction. Here, we show that only dual delivery of a combination of angiogenic and arteriogenic factors to the ischemic myocardium could significantly reestablish stable collateral networks and improve myocardial perfusion and function. A combination of FGF-2 with PDGF-BB, two factors primarily targeting endothelial cells and vascular smooth muscle cells, remarkably promotes myocardial collateral growth and stabilizes the newly formed collateral networks, which significantly restore myocardial perfusion and function. Using various members of the PDGF family together with FGF-2 in an angiogenesis assay, we demonstrate that PDGFR-alpha is mainly involved in angiogenic synergism, whereas PDGFR-beta mediates vessel stability signals. Our findings provide conceptual guidelines for the clinical development of proangiogenic/arteriogenic factors for the treatment of ischemic heart disease.
ZOIL : A Cross-Platform User Interface Paradigm for Personal Information Management (2008)

In this paper we introduce the novel user interface paradigm ZOIL (Zoomable Object-Oriented Information Landscape). ZOIL is aimed at unifying all types of local and remote information items with their connected functionality and with their mutual relations in a single visual workspace as a replacement of today’s desktop metaphor. This workspace can serve as an integrated work environment for traditional personal information management (PIM), but can also be used for PIM tasks in a wider sense. By formulating ZOIL’s fundamental design principles we describe the interaction style, visualization techniques and interface physics of a ZOIL user interface. Furthermore we discuss ZOIL’s ability to provide nomadic PIM environments for mobile and stationary use. Author Keywords personal information management, post-WIMP user interfaces, information visualization, zoomable user interfaces, object-oriented user interfaces. ACM Classification Keywords H5.2.

Stereograms through a speckle carrier (1983)

A new method for registering stereograms in which an orientated speckle pattern supplies the desired directivity for obtaining horizontal parallax is presented. This is accomplished by employing an optical system whose pupil consists of a double-fan aperture. In this way, the stereogram has a built-in reconstruction mechanism, and the stereo image can be observed with almost any extended white light source and without using any optical device. Furthermore, more than two points of view of the 3-D scene can be stored in a single plate by adequate positioning of the above-mentioned aperture.

Photoreactive UV-Crosslinkable Pressure-Sensitive Adhesives Based on Butyl Acrylate and 4-Acryloyloxy Benzophenone Copolymers (2013)

It has been previously shown that copolymers synthesized from n-butyl acrylate and unsaturated photoinitiator 4-acryloyloxy benzophenone can be used as pressure-sensitive adhesives (PSA). This paper presents synthesis and application of solvent-borne copolymer system for the preparation of photoreactive UV-crosslinkable acrylic pressure-sensitive adhesives comprising n-butyl acrylate/ benzophenone copolymers, characterized by molecular mass in the range of 180 000 to 480 000 Dalton. These copolymers were tacky but possessed insufficient cohesive strength after UV-crosslinking to be useful as PSA. They resulted in materials having a balance of cohesive and adhesive characteristics required of good PSA. Some of the parameters affecting the pressure-sensitive adhesive properties of the copolymer are: amount of the 4-acryloyloxy benzophenone, molecular mass of the polymeric components, UV-reactivity and properties, such as tack, peel adhesion and shear strength.
Serum leptin concentrations in obese women with Down syndrome and Prader–Willi syndrome (1999)

We have evaluated serum leptin concentrations in two forms of genetic obesity. The subjects examined were eight women with Down syndrome and eight women with Prader-Willi syndrome. All patients were in the reproductive age range and were obese (body mass index > or = 27 kg/m2). Plasma leptin values, analyzed as a function of body mass index showed a statistically significant correlation in both Prader-Willi (r = 0.985; p < 0.001) and Down syndrome patients (r = 0.943; p < 0.001). Obese Down syndrome women exhibited significantly lower leptin values (10.8 +/- 1.1) as compared to patients with Prader-Willi syndrome (31 +/- 2.6; p < 0.01). The linear correlation between leptin and insulin in the two groups of patients was not statistically significant. The data suggested that obesity in Prader-Willi subjects could be caused by failure of leptin to reach its target in the brain, as a consequence of defects in the receptor or in postreceptor processing, whereas data on obese patients with Down syndrome could be due to a different pathogenetic origin.

<i>N</i>‐Myristoylation of recoverin enhances its efficiency as an inhibitor of rhodopsin kinase (1995)

Recoverin, a recently identified member of the EF-hand superfamily of Ca(2+)-binding proteins, is capable to inhibit rhodopsin phosphorylation by rhodopsin kinase at high but not at low free [Ca2+]. The N-terminal glycine residue of retinal recoverin is heterogeneously acylated with myristoyl or related N-acyl group. To clarify the role of the N-terminal acylation of recoverin in its inhibitory action upon rhodopsin phosphorylation, we compared the efficiency of myristoylated and non-myristoylated forms of recombinant recoverin as inhibitors of rhodopsin kinase activity. We have found that rhodopsin phosphorylation by purified rhodopsin kinase, which does not depend on free [Ca2+] in the absence of recoverin, is regulated by Ca2+ in the presence of both forms of the recombinant protein. EC50 values for Ca2+ are the same (2 microM) for the myristoylated and non-myristoylated forms; the Hill coefficients of 1.7 and 0.9, respectively, indicate that the effect is cooperative with respect to Ca2+ only for myristoylated recoverin. In the presence of Ca2+, both forms of recoverin taken at saturated concentrations cause an almost equal inhibition of rhodopsin phosphorylation. However, the inhibitory action of the myristoylated form occurs at much lower its concentrations than that of the non-myristoylated form (EC50 are 0.9 and 6.5 microM, respectively).
Glucagon-Like Peptide-1 Receptor Activation Antagonizes Voltage-Dependent Repolarizing K+ Currents in β-Cells (2002)

Glucagon-like peptide-1 (GLP-1) acts through its G-protein-coupled receptor to enhance glucose-stimulated insulin secretion from pancreatic beta-cells. This is believed to result from modulation of at least two ion channels: ATP-sensitive K(+) (K(ATP)) channels and voltage-dependent Ca(2+) channels. Here, we report that GLP-1 receptor signaling also regulates the activity of beta-cell voltage-dependent K(+) (K(V)) channels, themselves potent glucose-dependent regulators of insulin secretion. GLP-1 receptor activation with exendin 4 (10(-8) mol/l) in rat beta-cells antagonized K(V) currents by 43.3 +/- 6.3%, whereas the GLP-1 receptor antagonist exendin 9-39 had no effect. The effect of GLP-1 receptor activation on K(V) currents could be replicated (current reduction of 55.7 +/- 6.0%) by G-protein activation with GMP-PNP (10 nmol/l). The cAMP pathway antagonist Rp-cAMPS (100 micro mol/l) prevented current inhibition by exendin 4, implicating cAMP signaling in GLP-1 receptor modulation of beta-cell K(V) currents. Finally, exendin 4 (10(-8) mol/l) increased the amplitude (130 +/- 5.7%) and duration (285 +/- 15.9%) of the beta-cell depolarization response to current injection, independent of any effect on K(ATP) or Ca(2+) channels. The present results demonstrate that GLP-1 receptor signaling can antagonize beta-cell repolarization by reducing voltage-dependent K(+) currents, an effect likely to contribute to GLP-1's glucose-dependent insulinotropic effect.
Convergent and Discriminant Validity of the Personality Inventory for Children (1987)

The Personality Inventory for Children (PIC) was compared with measures of cognitive functioning (e.g., WISC-R) and classroom behavior (e.g., WPBIC). The results demonstrated that the PIC can identify salient personality and cognitive features of learning-disabled, emotionally disturbed, and intellectually handicapped children. Furthermore, correlations between the PIC profile scales and the WISC-R showed that the majority of significant correlations clustered around PIC scales intended to identify cognitive deficits, whereas significant correlations with the WPBIC were with PIC scales intended to identify disruptive, acting-out behavior. These relationships provide support for both the construct validity and diagnostic potential of the PIC with children referred for special education services.

Method for gene replacement in Pseudomonas aeruginosa used in construction of recA mutants: recA-independent instability of alginate production (1985)

The availability of a technique for site-directed mutagenesis by gene replacement provides a powerful tool for genetic analysis in any bacterial species. We report here a general technique for gene replacement in Pseudomonas aeruginosa. Genes on fragments of cloned P. aeruginosa DNA, altered by transposon mutagenesis, can be transduced into a recipient strain and can replace homologous genes in the P. aeruginosa genome. In this study we applied this technique to the construction of recA mutants of P. aeruginosa. A cloned segment of P. aeruginosa FRD1 DNA was isolated which encoded a protein analogous to the recA gene product of Escherichia coli. The P. aeruginosa recA gene was able to complement several defects associated with recA mutation in E. coli. Transposon Tn1 and Tn501 insertions in the cloned recA gene of P. aeruginosa were used to generate chromosomal recA mutants by gene replacement. These recA strains of P. aeruginosa were more sensitive to UV irradiation and methyl methane sulfonate and showed reduced recombination proficiency compared with the wild type. Also examined was the effect of recA mutations on the expression of alginate, a virulence trait. Alginate is a capsulelike polysaccharide associated with certain pulmonary infections, and its expression is typically unstable. The genetic mechanism responsible for the instability of alginate biosynthesis was shown to be recA independent.
