A new incident illuminator for polarizing microscopes (1964)

Summary The customary illumination by a ‘coverglass’ inclined at 45 degrees is replaced by a double reflection. The beam from the horizontal collimating tube is first reflected from a highly reflecting mirror at the back of the unit, then downward from a coverglass placed at the top of the unit. With this arrangement the coverglass is inclined at less than 22½ degrees to the axis of the microscope, with a similar reduction of the angle of incidence. The correction ratio for rotation by upward passage of light through the coverglass is now reduced from 6:5 to the almost negligible value 21:20. There is a corresponding improvement in the homogeneity of extinction over the microscope field.
3D Modeling from Wide Baseline Range Scans Using Contour Coherence (2014)

Registering 2 or more range scans is a fundamental problem, with application to 3D modeling. While this problem is well addressed by existing techniques such as ICP when the views overlap significantly at a good initialization, no satisfactory solution exists for wide baseline registration. We propose here a novel approach which leverages contour coherence and allows us to align two wide baseline range scans with limited overlap from a poor initialization. Inspired by ICP, we maximize the contour coherence by building robust corresponding pairs on apparent contours and minimizing their distances in an iterative fashion. We use the contour coherence under a multi-view rigid registration framework, and this enables the reconstruction of accurate and complete 3D models from as few as 4 frames. We further extend it to handle articulations, and this allows us to model articulated objects such as human body. Experimental results on both synthetic and real data demonstrate the effectiveness and robustness of our contour coherence based registration approach to wide baseline range scans, and to 3D modeling.

Implanted near-infrared spectroscopy for cardiac monitoring (2011)

Implanted Cardioverter Defibrillator (ICD) provides one of the most effective therapies for the prevention of sudden cardiac death, but also delivers some high voltage shocks inappropriately, causing morbidity and mortality. Implanted near-infrared spectroscopy (NIRS) may augment ICD arrhythmia detection by monitoring skeletal muscle perfusion. A two-wavelength, single-distance, continuous-wave implanted NIRS has been evaluated in-vivo. A weighted difference of the changes in attenuation at two wavelengths, across the isobestic point of the hemoglobin spectra, was taken to be the microvascular oxygenation trend indicator (O2 Index). Although the exact weight depends on the local vascular distribution and their oxygen levels, the hypothesis that a constant weight may be adequate for hemodynamic trending during short arrhythmic episodes, was tested. The sensor was implanted subcutaneously both on fresh tissue and inside scar tissue that formed around a pre-existing implant, in 3 animals each. Attenuations were recorded at 660 and 890 nm during normal sinus rhythm (NSR) and induced ventricular fibrillation (VF). The slope of the O2 Index over 10 seconds was computed for 7 NSR and 8 VF episodes in fresh and 13 NSR and 15 VF episodes in scar tissue pockets. The mean O2 Index slope was significantly different (<i>p</i><0.0001) between NSR and VF rhythms for both the fresh and scar tissue pockets. Therefore implanted NIRS may be useful for preventing inappropriate detection of VF during electromagnetic interference, double counting of ECG T-wave as an R-wave, ICD lead failure, electrocardiographic aberrancy etc.
How crystals form: A theory of nucleation pathways (2019)

Recent advances in classical density functional theory are combined with stochastic process theory and rare event techniques to formulate a theoretical description of nucleation, including crystallization, that can predict nonclassical nucleation pathways based on no input other than the interaction potential of the particles making up the system. The theory is formulated directly in terms of the density field, thus forgoing the need to define collective variables. It is illustrated by application to diffusion-limited nucleation of macromolecules in solution for both liquid-liquid separation and crystallization. Both involve nonclassical pathways with crystallization, in particular, proceeding by a two-step mechanism consisting of the formation of a dense-solution droplet followed by ordering originating at the core of the droplet. Furthermore, during the ordering, the free-energy surface shows shallow minima associated with the freezing of liquid into solid shells, which may shed light on the widely observed metastability of nanoscale clusters.
An efficient battery balancing scheme in electric vehicle (2013)

This paper proposes a new balancing scheme for lithium ion battery, using inductance realizes energy transfer between the whole battery pack and single cell. The balanced circuit is composed of two groups of switches and an inductor. The scheme uses constant current mode, and its balancing current is controlled by a closed current loop adjusted by PI, so the balancing current is constant and controllable. Finally, in the environment of matlab-simulink, the experiments have been completed, and the experimental results prove that the balancing scheme is feasible and its balancing efficiency is high.
Robust End-to-End QoS Maintenance in Non-Contiguous OFDM Based Cognitive Radios (2008)

A recent development in wireless communication is Cognitive Radio (CR) technology, an innovative radio design approach which allows the realization of intelligent allocation of the scarce radio resources such as spectrum. In this paper, we attempt to exploit past channel information and the flexibility of non-contiguous orthogonal frequency division multiplexing (NC- OFDM) based CRs to maintain end-to-end QoS performance under dynamic spectrum sharing environments. So far, most research works in resource allocation in CRs have mainly concentrated on the spectrum opportunity discovery aspect while the robust QoS performance problem has remained largely unexplored. In this work, we use the concept of portfolio optimization to achieve QoS maintenance in NC-OFDM CR systems. The problem of allocating power to maintain throughput is cast into a channel gain variance minimization and mean- variance maximization frameworks to achieve a given throughput performance under fixed BER and power limitation constraints. Numerical results are presented to demonstrate the QoS maintenance performance in various wireless channel settings.
Improved resolution for 3D position sensitive CdZnTe spectrometers (2005)

Two 3-dimensional position sensitive CdZnTe gamma-ray spectrometers based on VAS/TAT ASICs were developed and fully tested. The 1.5/spl times/1.5/spl times/1 cm/sup 3/ CdZnTe detectors employ 11/spl times/11 pixellated anodes wire-bonded to the readout electronics The pixel number provides the interaction's lateral coordinates, while the cathode/anode signal ratio and the electron drift time are used to obtain the interaction depth. Data-acquisition and processing software were developed to perform calibration and real-time spectroscopy. An energy resolution of 1.11% FWHM at 662 keV was obtained for single-pixel events from the 120 working pixels of one detector, and an energy resolution of 1.14% FWHM was obtained on the other detector. Significant progress in improving energy resolution for multiple pixel events has been realized. The energy resolution at 662 keV for two-pixel events and three-pixel events were 1.57% FWHM and 2.13% FWHM respectively.
Targeting Asymptomatic Malaria Infections: Active Surveillance in Control and Elimination (2013)

Hugh Sturrock and colleagues discuss the role of active case detection in low malaria transmission settings. They argue that the evidence for its effectiveness is sparse and that targeted mass drug administration should be evaluated as an alternative or addition to active case detection.

Direct Appeals from Bankruptcy Courts to the Courts of Appeals: The Experience after Two Years (2007)

Until recently, there was no way to appeal a bankruptcy case directly from a bankruptcy court to a court of appeals.Instead, the case had to be first appealed to the district court[ or bankruptcy appellate panel. 2 Only after that court or BAP had ruled could the case be heard in the court of appeals. 3 That changed in the Bankruptcy Abuse Prevention and Consumer Protection Act of 2005 ("BAPCPA"), 4 which provides in some circumstances for direct review of bankruptcy court orders by the courts of appeals. 5
Splitting the organization and integrating the code (1999)

It is widely acknowledged that coordination of large scale software development is an extremely difficult and persistent problem. Since the structure of the code mirrors the structure of the organization, one might expect that splitting the organization across time zones, cultures, and (natural) languages would make it difficult to assemble the components. This paper presents a case study of what indeed turned out to be the most difficult part of a geographically distributed software project, i.e., integration. Coordination problems were greatly exaggerated across sites, largely because of the breakdown of informal communication channels. The results imply that multi-site development can benefit to some extent from stable plans, processes, and specifications. The inherently unpredictable aspects of projects, however, require communication channels that can be invoked spontaneously, by developers, as needed. These results shed light on the problems and mechanisms underlying the coordination needs of development projects generally, be they co-located or distributed.
Improving the temporal flexibility of position constrained metric temporal plans (2003)

In this paper we address the problem of post-processing position constrained plans, output by many of the recent efficient metric temporal planners, to improve their execution flexibility. Specifically, given a position constrained plan, we consider the problem of generating a partially ordered (aka &quot;order constrained&quot;) plan that uses the same actions.
Overview of the Physical State of Proteins Within Cells (1998)

Proteins, the end product of gene expression, play a pivotal role in cellular structure and function. To understand how proteins work it is necessary to understand their physical state within the cell. This unit reviews the classification of proteins, how that is related to the hydropathicity of the protein, other factors that affect the heterogeneity of proteins, protein assemblies, methods for altering the solubility of proteins, and limitations of in vitro manipulations of proteins.
Assignment of the chromosomal locus of the human 30-kDal Rh (Rhesus) blood group-antigen-related protein (Rh30A) to chromosome region 1p36.13→p34 (1992)

Using a panel of somatic cell hybrids, we have localised the 30-kDal Rhesus blood group-antigen-related protein to human chromosome 1 in the region p36.13----p34. This confirms the localisation of this protein described previously using cytogenetic and linkage analyses.
Bone Quantity and Quality of Youths Working on a Farm—A Pilot Study (2008)

This study investigated the effect of farm-related activities on the bone health of youths. Bone quantity and bone quality were quantitated in 36 adolescents-18 youth with a history of working on farms and 18 youth not involved in farm-related activities. Bone quantity as depicted by bone mineral density (BMD) was measured with dual-energy x-ray absorptiometry. Bone quality was characterized with biomechanical measures based on bone geometry and measures of dynamic bone shock absorption (BSA) properties. Dynamic bone response measures provide preliminary evidence that farm-related physically demanding tasks lead to changes that may predispose the teenagers to degenerative skeletal disorders later in life. Future studies with larger samples need to be carried out to further support the findings.
Serologic Responses and Systemic Reactions in Adults After Vaccination with Monovalent A/USSR/77 and Trivalent A/USSR/77, A/Texas/77, B/Hong Kong/72 Influenza Vaccines (1983)

Four hundred twenty-six volunteers aged 16 to 83 years were given experimental doses of inactivated monovalent [A/USSR/77 (H1N1)] and trivalent [A/USSR/77 (H1N1), A/Texas/77 (H3N2), B/Hong Kong/72] influenza vaccines as part of a double-blinded, placebo-controlled, national collaborative study. Local reactions at inoculation sites occurred in less than 6.6% of volunteers. Systemic reactions, generally consisting of low-grade fever, myalgia, or headache, lasting less than 24 hr, did not occur more frequently in vaccinees than in placebo recipients. Vaccines containing lower doses of the A/Texas/77 (H3N2) hemagglutinin (8-10 micrograms) and B/Hong Kong/72 hemagglutinin (6-9 micrograms) produced hemagglutinin-inhibiting (HAI) antibody responses equivalent to those produced by higher doses (15-28 and 19-28 micrograms, respectively) in all age groups. Single injections of vaccines containing lower doses of A/USSR/77 (H1N1) hemagglutinin (4-7 micrograms) induced titers of HAI antibody of greater than 1:40 in 93% of volunteers greater than or equal to 26 years of age but in only 58% of volunteers less than 26 years of age. In this latter group, two injections containing higher doses (10-19 micrograms) induced better antibody responses. Vaccines containing approximately 6-15 micrograms of hemagglutinin of each antigen can be expected to be well tolerated and to induce good HAI antibody responses in a one- or two-dose regimen, depending on the age group.
Monosialoganglioside‐Containing Nanoliposomes Restore Endothelial Function Impaired by AL Amyloidosis Light Chain Proteins (2016)

NLGM1 protects against LC-induced human microvascular endothelial dysfunction through increased nitric oxide bioavailability and reduced oxidative and nitrative stress mediated by Nrf-2-dependent antioxidant stress response. These findings point to a potential novel therapeutic approach for light chain amyloidosis.
[Effects of interferon-beta on repair of the retinal pigment epithelium after laser photocoagulation]. (1995)

We studied the morphological effects of human interferon-beta on repair of the retinal pigment epithelium (RPE) after moderate dye laser photocoagulation in monkey eyes. In the control eyes, RPE cells were proliferating towards the center from the margin of the laser burn 3 days after photocoagulation. At day 14 after photocoagulation, a newly formed monolayer of RPE cells covered Burch's membrane to repair the lesion. In the eyes treated with interferon-beta by systemic administration, RPE cells had proliferated remarkably 3 days after photocoagulation. The RPE cells proliferated to form multiple layers on Burch's membrane even at day 14 after photocoagulation. These results suggest that interferon-beta promotes the proliferation to repair damaged RPE.
A Biologically Active Sequence of the Laminin α2 Large Globular 1 Domain Promotes Cell Adhesion through Syndecan-1 by Inducing Phosphorylation and Membrane Localization of Protein Kinase Cδ (2009)

Laminin-2 promotes basement membrane assembly and peripheral myelinogenesis; however, a receptor-binding motif within laminin-2 and the downstream signaling pathways for motif-mediated cell adhesion have not been fully established. The human laminin-2 alpha2 chain cDNAs cloned from human keratinocytes and fibroblasts correspond to the laminin alpha2 chain variant sequence from the human brain. Individually expressed recombinant large globular (LG) 1 protein promotes cell adhesion and has heparin binding activities. Studies with synthetic peptides delineate the DLTIDDSYWYRI motif (Ln2-P3) within the LG1 as a major site for both heparin and cell binding. Cell adhesion to LG1 and Ln2-P3 is inhibited by treatment of heparitinase I and chondroitinase ABC. Syndecan-1 from PC12 cells binds to LG1 and Ln2-P3 and colocalizes with both molecules. Suppression of syndecan-1 with RNA interference inhibits cell adhesion to LG1 and Ln2-P3. The binding of syndecan-1 with LG1 and Ln2-P3 induces the recruitment of protein kinase Cdelta (PKCdelta) into the membrane and stimulates its tyrosine phosphorylation. A decrease in PKCdelta activity significantly reduces cell adhesion to LG1 and Ln2-P3. Taken together, these results indicate that the Ln2-P3 motif and LG1 domain, containing the motif, within the human laminin-2 alpha2 chain are major ligands for syndecan-1, which mediates cell adhesion through the PKCdelta signaling pathway.
Speed of sound in seawater as a function of temperature and salinity at one atmosphere (1975)

The speed of sound in standard seawater (diluted with pure water and evaporated) has been measured relative to pure water with a Nusonics velocimeter as a function of temperature (0 to 40°C, at 5° intervals) and salinity (5 to 40 0/00, at 5 0/00 intervals) at a atm. The results have been fitted to an equation of the form c = c0 + A S (0/00) + B S (0/00)3/2 + C S (0/00)2, where c0 is the speed of sound in pure water, S (0/00) is the salinity in parts per thousand, and A, B, and C are temperature−dependent parameters. The sound speeds fit this equation to a standard deviation of 0.04 m sec−1 over the entire temperature and salinity range. Over the oceanographic range our results, on the average, agree with the work of Wilson to ±0.5 m sec−1 (max 1.08 m sec−1) and with the work of Del Grosso and Mader to ±0.05 m sec−1 (max 0.14 m sec−1). In the low−salinity range, (5−25 0/00 salinity) our results, on the average, agree with the work of Wilson to ±0.3 m sec−1 (max 1.1 m sec−1) and with the work of Del Grosso and Mader to within ±0.1 m sec−1 (max 0.20 m sec−1). From these comparisons it is clear that the 1−atm sound speeds of Del Grosso and Mader are more reliable than those determined by Wilson over the oceanographic range as well as at lower salinities (which is outside of the range of Del Grosso and Mader’s measurements). The adiabatic and isothermal compressibilities of seawater solutions reliable to ±0.003×10−6 bar−1 have been determined from the sound speeds. The isothermal compressibilities are in excellent agreement (avg. dev. ±0.02×10−6 bar) with the direct measurements of Lepple and Millero. The specific heat of seawater solutions at constant volume has also been determined from the sound−derived isothermal compressibilities. Subject Classification: 30.25.
DNA macroarray study of skin aging‐related genes expression modulation by antioxidant plant extracts on a replicative senescence model of human dermal fibroblasts (2010)

The formation of reactive oxygen species (ROS) is a widely accepted pivotal mechanism leading to skin aging. It increases with age, while the endogenous defense mechanisms that counter them decrease. This imbalance, called oxidative stress, leads to the progressive damage of cellular structures and results in accelerated aging. Antioxidant compounds can provide protection from endogenous and exogenous oxidative stress by scavenging free radicals. The main phenolic compounds of oak wood, mate leaf and benjoin resin antioxidant extracts were identified and the effects of these extracts on skin aging markers were evaluated using DNA macroarray technology. The transcriptional effect of the three antioxidant extracts was evaluated in vitro on a replicative senescence model of normal human dermal fibroblasts (NHDF), using a customized DNA macroarray specifically designed to investigate aging markers such as dermal structure, cell renewal, inflammatory response and oxidative stress mechanisms. Among the 149 genes detected, the three antioxidant extracts presented a significant regulation of five genes involved in inflammatory response, cell renewal and antioxidant defenses. The collective transcriptional effects of these extracts suggest interesting antiaging properties which could be utilized in nutraceutical antiaging formulations.
Fischlar on a PDA: handheld user interface design to a video indexing, browsing and playback system. (2001)

The Físchlár digital video system is a web-based system for recording, analysis, browsing and playback of TV programmes which currently has about 350 users. Although the user interface to the system is designed for desktop PCs with a large screen and a mouse, we are developing versions to allow the use of mobile devices to access the system to record and browse the video content. In this paper, the design of a PDA user interface to video content browsing is considered. We use a design framework we have developed previously to be able to specify various video browsing interface styles thus making it possible to design for all potential users and their various environments. We can then apply this to the particulars of the PDA's small, touch-sensitive screen and the mobile environment where it will be used. The resultant video browsing interfaces have highly interactive interfaces yet are simple, which requires relatively less visual attention and focusing, and can be comfortably used in a mobile situation to browse the available video contents. To date we have developed and tested such interfaces on a Revo PDA, and are in the process of developing others.
Expression profiling of ion channel genes predicts clinical outcome in breast cancer (2013)

We identified a molecular gene signature IC30, which represents a promising diagnostic and prognostic biomarker in breast cancer. Our results indicate that information regarding the expression of ion channels in tumor pathology could provide new targets for therapy in human cancers.
A poly(A) binding protein-specific sequence motif: MRTENGKSKGFGFVC binding to mRNA poly(A) and polynucleotides and its role on mRNA translation. (1994)

A consensus sequence (GKSKGFGFV) was recognized in all the sequenced poly(A) binding proteins. We synthesized a 15-amino acid peptide (corresponding to 354-368 in the yeast poly(A) binding protein) which includes the consensus sequence to test its binding affinity to different nucleotides, polynucleotides and mRNA with or without a poly(A) tail. Biochemical and biophysical studies revealed that the 15-amino acid peptide has a strong binding affinity to poly(A) alone or poly(A) attached at the 3' end of mRNA. Circular dichroism spectroscopy demonstrated that the secondary structure of the 15-mer is consistent with that expected based on the structure of the native RNP domain. Furthermore, among the various mononucleotides performed in the present studies, ATP was preferentially found to bind to the 15-mer. To further examine the biological significance of the binding of the 15-mer to the poly(A) tail of mRNA, in vitro translation of the mRNA poly(A)+ in the presence of the 15-mer drastically increased globin synthesis by almost 2-fold, while translation of the deadenylated mRNA in the presence of the 15-mer almost did not alter the rate of incorporation of radiolabeled leucine into globin.
