Segmentation in clutter (2010)

In a cluttered scene, it may be difficult to fully segment an object using only bottom-up cues. In such cases we may segment the object by first detecting one of its salient, distinctive parts and then using this part to predict the location and orientation of other object parts. For a rigid object, the predictive power of the salient part should depend on its symmetry. For example, a sphere which has infinite rotational symmetry (and so looks the same from all viewpoints) should have less predictive power than a cone. To test this idea we constructed computer-generated, rigid objects composed of two pieces: a “handle” (a simple geometric shape) and a “tool” (two connected cylinders). In each scene, an object was presented at a random orientation amongst clutter composed of cylinders resembling the tool. A small black or white ring was placed around one of the tool's cylinders at a location that varied across trials. Similar rings were also placed on the clutter. The observer's task was to report the color of the ring located on the tool. Because the tool was camouflaged against the background of clutter, response times were expected to depend on the degree to which the salient handle could be used to predict the tool's location and orientation in the clutter. That is, response times were expected to depend on the symmetry of the handle. The results supported this idea: response times increased monotonically as the symmetry of the handle increased from 0-fold to 2-fold to 4-fold. Response times for handles with infinite symmetry, however, were no longer than those with 4-fold symmetry. We conclude that observers can use a salient part to predict the location and orientation of the rest of an object. The predictive power of these salient parts depends, up to a limit, on their symmetry.
A hybrid superoxide dismutase containing both functional iron and manganese. (1984)

A hybrid superoxide dismutase containing functional Mn and Fe has been isolated from Escherichia coli. Streptomycin, which binds tightly to both the Mn- and the Fe-containing superoxide dismutases, had the expected effect on the electrophoretic and chromatographic behavior of the hybrid. Treatment of the hybrid with H2O2, which selectively inactivates the Fe-containing enzyme, resulted in partial inactivation accompanied by a resegregation of subunits, with the formation of active Mn-enzyme and inactive Fe-enzyme. A similar resegregation of subunits was observed when the hybrid was exposed to 2.5 M guanidinium chloride. Hybrids containing Mn or Fe could be generated in vitro by mixing the Mn-enzyme with the Fe-enzyme, removing metals with 8-hydroxyquinoline in the presence of 2.5 M guanidinium chloride, and then dialyzing against Mn(II) or Fe(II) salts. Ten per cent of the activity of the Fe-superoxide dismutases is resistant to H2O2, which correlates with its content of Mn. Since the activity remaining after exhaustive treatment with H2O2 exhibited the electrophoretic mobility of the Fe-enzyme, we concluded that some of the active sites of the Fe-enzyme were actually occupied by Mn. It should be noted, however, that for purposes of metal reconstitution experiments, a definite specificity was demonstrated. The Mn-enzyme was reconstituted with Mn(II), whereas the Fe-enzyme activity was recovered using only Fe(II). We propose that the Fe-superoxide dismutase may be heterogeneous and that 10% of its activity is actually due to a Mn-containing variant with the same electrophoretic mobility. Only the apohybrid enzyme regained enzymatic activity using both Mn(II) and Fe(II).

Effects of enalapril, candesartan or both on neurohumoral activation and LV volumes and function in patients with heart failure not treated with a beta-blocker (2009)

We conclude that angiotensin-II modulation, with enalapril and candesartan, without concomitant utilization of beta-blocker lead to a decrease in BNP and an attenuation of the increase in LV end-diastolic and end-systolic volumes without a reversal of this process in the long term.
Evolving robust gender classification features for CAESAR data (2011)

In this paper we explore the robustness of histogram features extracted from 3D point clouds of human subjects for gender classification. Experiments are conducted using point clouds drawn from the Civilian American and European Surface Anthropometry Resource Project (CAESAR anthropometric database provided by the Air Force Research Laboratory (AFRL) Human Effectiveness Directorate and SAE International). This database contains approximately 4400 high resolution LIDAR whole body scans of carefully posed human subjects. Features are extracted from each point cloud by embedding the cloud in series of cylindrical shapes and computing a point count for each cylinder that characterizes a region of the subject. These measurements define rotationally invariant histogram features that are processed by a classifier to label the gender of each subject. Preliminary results using cylinder sizes defined by human experts demonstrate that gender can be predicted with 98% accuracy for the type of high density point cloud found in the CAESAR database. In our previous has shown that when point cloud densities are reduced to levels that might be obtained using stand-off sensors; gender classification accuracy degrades. In this paper we show the results of how the classification accuracy degrades as a function of center of mass displacements.
Towards a cognitive robot that uses internal rehearsal to learn affordance relations (2008)

This paper introduces a new approach to develop robots that can learn general affordance relations from their experiences. Our approach is a part of larger efforts to develop a cognitive robot and has two components: (a) the robot models affordances as statistical relations among actions, object properties and the effects of actions on objects, in the context of a goal that specifies preferred effects and outcomes, (b) to exploit the general-knowledge potential of actual experiences, the robot engages in internal rehearsal by playing out virtual scenarios grounded in yet different from actual experiences. To the extent the robot accurately appreciates affordance relations, the robot can autonomously predict the outcomes of its behaviors before executing them. Internal rehearsal-based outcome production in turn facilitates planning of a sequence of behaviors toward successful task execution. We also report simulation results of internal rehearsal-based traversability affordance learning of a humanoid robot.
Engaging patients in therapeutic development (2020)

Abstract Engagement of patients during the development of new treatments has evolved rapidly in the last decade. No longer should patients be viewed as passive subjects of research: they should be active participants in a more open and ambitious ecosystem of academic investigators, companies, and government entities. Enhanced engagement of patients throughout the development process provides important benefits for the introduction of useful and effective drugs by changing the understanding of the disease, the measurement of the disease during treatment, and the interpretation of benefit-risk. This system is critical for the discovery, study, development, regulation, delivery, and use of innovative therapies.
Is increased blinking a form of blepharospasm? (2013)

Our study shows that, despite the similar STDT abnormalities, the different changes in the R2 recovery cycle in patients with BSP and those with increased BR alone suggest that these disorders arise from different pathologic mechanisms.

The chemical basis of protein splicing (1998)

Protein splicing is a recently discovered mechanism for the post-translational processing of proteins. It involves the self-catalyzed excision of an intervening polypeptide, the intein, from an inactive enzyme precursor and the formation of an active enzyme by joining the flanking regions by a peptide bond. Protein splicing occurs at a catalytic center that resides entirely within the intein. The catalyzed reactions include rearrangement of a peptide bond adjacent to cysteine or serine to yield a peptide ester, intramolecular transesterification involving a second cysteine, serine, or threonine side chain to yield a branched protein, and cyclization of an asparagine residue coupled to peptide bond cleavage to effect intein excision. This review discusses the mechanisms of these reactions and of similar reactions that underlie other types of protein rearrangements as well as the current state of knowledge on how these reactions are catalyzed.
USING DRY MOUNTED FREEZE-DRIED SECTIONS FOR LOCALIZATION OF CARCINOGENS IN THE LUNG' (1974)

A major problem in determining the microscopic localization of soluble compounds in tissues is the use of’the liquids involved in tissue processing which may transport the compound from its site of’origin in vito. The preparation of’ specimens by conventional techniques for the microscopic analysis of the localization of radiolabeled carcinogens in the lung involves liquid fixatives, dehydration and clearing fluids, infiltration and embedding media and wet section mounting. Any or all of these steps may lead to the artifactual translocation of the carcinogen from itsin vivo active site. One way of’ minimiz
Trisomy 7 in keratoacanthoma and squamous cell carcinoma detected by fluorescence in‐situ hybridization (1995)

Keratoacanthoma (KA) is generally considered to be a clinically and histologically distinct entity, but it often remains difficult to separate from well-differentiated squamous cell carcinoma (WDSCC). Recently, trisomy 7 has been identified in squamous cell carcinoma of the skin. In this study, we examined classical KA (n = 6), WDSCC (n = 7) and squamous cell carcinoma with KA-like features (SCC-KA) (n = 8) for trisomy 7 by fluorescence in-situ hybridization (FISH) to determine if this chromosomal abnormality is unique to squamous lesions diagnosed as WDSCC, or shared by both KA and SCC. In addition, the pertinent clinical-histopathologic findings were summarized. Trisomy 7 was identified in one KA, one SCC-KA and two WDSCC. This study demonstrates that there is a chromosomal abnormality shared by KA and SCC, providing further evidence that KA is most likely a form of SCC. Further studies are required to determine if trisomy 7 in these lesions is of prognostic significance.

Mechanisms of Defect Passivation by Fluorinated Alkylthiolates on PbS Quantum Dots (2018)

Defects in the organic ligand layers on the surfaces of colloidal quantum dots (QDs) provide pathways for corrosive molecules to penetrate to the QD core. This paper describes the decrease in the permeability of the ligand shells of colloidal near-infrared-emitting PbS QDs to the molecular photo-oxidant, duroquinone (Me4BQ), upon substituting a small fraction of their oleate ligands with either 1-dodecanethiolate (DDT) or progressively fluorinated DDT analogues (with between 1 and 10 fluorinated carbons), as measured by the yield of collisionally gated photoinduced electron transfer from the QD to Me4BQ. The permeabilities of mixed-monolayer ligand shells of oleate and 8–16% (by surface area) DDT are 35–41% lower than those of the pure oleate monolayers. Increasing the number of fluorinated carbons in the thiolate ligands from 0 to 10 results in an additional 40–66% decrease in the permeability of the ligand shell; as few as 0.05% of collisions between the largest QDs and Me4BQ result in electron transfer. The thiolate exchange, and fluorination of the thiolate ligands, more effectively protect the largest QDs than the smallest QDs, primarily due to the size-dependence of the types of defects in the native oleate monolayers.

Characterization of piezoelectric single crystal YCa4O(BO3)3 for high temperature applications (2008)

Operation at temperatures well above ambient is desired for applications such as smart structures integrated within aircraft and space vehicles. Piezoelectric yttrium calcium oxyborate single crystal YCa4O(BO3)3 (YCOB) was found to exhibit no phase transition until its melting temperature around ∼1500°C. The temperature characteristics of the resonance frequency, electromechanical coupling, and dielectric permittivity were studied in the temperature range of 30–950°C for different orientations. The electrical resistivity at 800°C was found to be greater than 2×108Ωcm. Together with its temperature independent electromechanical coupling factor (∼12%) and engineered resonance frequency behavior, these make YCOB crystals excellent candidates for sensing applications at ultra high temperatures.
Failure to detect evidence of human immunodeficiency virus type 1 (HIV‐ 1) infection by polymerase chain reaction assay in blood donors with isolated core antibodies (anti‐p24 or ‐p17) to HIV‐1 (1990)

Individuals with isolated and persistent core antibodies (anti-p24 or -p17) to HIV-1 are sometimes diagnosed through the systematic screening of blood donations. The significance of such serum reactivities remains unknown. Polymerase chain reaction (PCR) is a new technique allowing the direct detection of HIV-1 DNA in blood samples. In this study, PCR was used to detect HIV-1 DNA in 20 individuals with isolated and persistent core antibodies (14 anti-p24 and 6 -p17), in seven sexual partners of these individuals, in 55 HIV-1-seropositive individuals (positive controls), and in 105 HIV-1-seronegative blood donors at low risk of HIV-1 infection (negative controls). No HIV-1 DNA was detected in individuals with isolated and persistent core antibodies, in their sexual partners, or in negative control individuals, although PCR was positive in 54 of 55 seropositive control individuals. These results strongly suggest that individuals with isolated and persistent core antibodies are not infected with HIV-1.
Fc Receptor-Bearing Lymphoid Cells in the Chicken II. Relative Increase of Fc(IgG) Receptor Bearing Cells in Obese Strain Chickens (1978)

An EA rosette technique is used to study ontological development and organ distribution of Fc(IgG) receptor-bearing lymphoid cells in normal CS White Leghorn chickens, and in OS chickens with spontaneous autoimmune thyroiditis. During the embryonic period, no difference was seen between CS and OS in the tissue distribution of cells with Fc receptors. At the time of hatching and subsequently, the OS chickens possessed relatively more Fc receptor-bearing lymphoid cells than did CS chickens. The increase of Fc receptor-bearing lymphoid cells was most prominent among spleen cells. No difference in the affinity of Fc receptors between lymphocytes of the OS and CS chickens was demonstrated. The possible role of Fc receptor-carrying cells in the development of autoimmune thyroiditis is discussed.

Improvising camera control for capturing meeting activities using a floor plan (2001)

This paper describes camera control interfaces for capturing meetings and presentations into multimedia documents. While technologies are maturing to deliver multimedia documents over network, skilled human hands are still required to create the contents. We had dug into the problem and found that some portion of it derives from current camera control systems, which only provide interfaces for incremental navigations. Presets are provided for some systems to avoid cumbersome manipulations, but the difficulty to improvise controls remains untouched. We introduced an interface using floor plan for selecting an arbitrary area to be captured. We also conducted a study to compare our method with other two typical camera control interfaces. The results revealed that our method was significantly better than a typical joystick-metaphor interface. Although an interface with presets resulted superior for completing tasks in limited conditions, the participants judge the use of a floor plan to be equally good in respect to ease of camera navigation as they intended. They also indicated possible improvement for our interface to close in on the one with presets.

<title>Medical prosthetic applications of growth simulations in four-dimensional facial morphology</title> (1991)

Growth data on the developing human face has been collected by scientists in a number ofdifferent disciplines for nearly one hundred years. Most of the work in this area has been the result of attempts to understand and quantify the growth process or in attempting to establish population norms or baseline standards for use in syndromology. Anthropologists geneticists ophthalmologists orthodontists otorhinolaryngologists pediatric syndromologists plastic surgeons radiologists have all contributed to the literature on facial development1. While this literature for facial assessment is very complete but its use and value in prediction has not been exploited to-date. The preliminary work presented in this paper uses the available literature to predict growth and development ofthe nose. These predictions were used in fabricating a series ofnasal prostheses that will be used to establish facial cosmesis during the growth years. This case involves a six year old male who had undergone a total rhinectomy and septectomy required a nose prosthesis to cover a severe facial defect and to effect cosmesis. Based on laser scan data from casts ofthe patient''s pre-surgical nose a selected series ofanthropometric landmarks were identified and scaled. Growth algorithms provided new positions for control points that simulated growth of the nose over time. The resulting series of geometric models were initially fabricated using stereolithography and later modeled in a medical grade silastic. Growth predictions used to simulate the morphological remodelling of facia
A Rapid Method for Laboratory Preparation of High Solids Casein and Caseinate Dispersions (1991)

A laboratory technique for the dispexsion of casein or caseinate into liquid using a food processor as the mixing tool is described. The liquid, as crushed ice, was aided to the processor before or after the casein or caseinate. The progress and completeness of mixing was monitored by variances of the moisture content of product sampled from different sections of the processing bowL Total time for complete dispersion was 8 min or less, much faster than other dispersion methods.
