Real-Time and Secure Wireless Health Monitoring (2008)

We present a framework for a wireless health monitoring system using wireless networks such as ZigBee. Vital signals are collected and processed using a 3-tiered architecture. The first stage is the mobile device carried on the body that runs a number of wired and wireless probes. This device is also designed to perform some basic processing such as the heart rate and fatal failure detection. At the second stage, further processing is performed by a local server using the raw data transmitted by the mobile device continuously. The raw data is also stored at this server. The processed data as well as the analysis results are then transmitted to the service provider center for diagnostic reviews as well as storage. The main advantages of the proposed framework are (1) the ability to detect signals wirelessly within a body sensor network (BSN), (2) low-power and reliable data transmission through ZigBee network nodes, (3) secure transmission of medical data over BSN, (4) efficient channel allocation for medical data transmission over wireless networks, and (5) optimized analysis of data using an adaptive architecture that maximizes the utility of processing and computational capacity at each platform.
Aligning point cloud views using persistent feature histograms (2008)

In this paper we investigate the usage of persistent point feature histograms for the problem of aligning point cloud data views into a consistent global model. Given a collection of noisy point clouds, our algorithm estimates a set of robust 16D features which describe the geometry of each point locally. By analyzing the persistence of the features at different scales, we extract an optimal set which best characterizes a given point cloud. The resulted persistent features are used in an initial alignment algorithm to estimate a rigid transformation that approximately registers the input datasets. The algorithm provides good starting points for iterative registration algorithms such as ICP (Iterative Closest Point), by transforming the datasets to its convergence basin. We show that our approach is invariant to pose and sampling density, and can cope well with noisy data coming from both indoor and outdoor laser scans.
Cellular and molecular responses of the uterus to embryo implantation can be elicited by locally applied growth factors (2001)

The implantation of a blastocyst into a receptive uterus is associated with a series of events, namely the attachment reaction followed by decidualization of the stroma. Previous studies established that the gene encoding heparin-binding EGF-like growth factor (HB-EGF) is expressed in the luminal epithelium solely at the site of blastocyst apposition preceding the attachment reaction. We report here the expression during implantation of 21 genes encoding other signaling proteins, including those belonging to the Bone morphogenetic protein (BMP), fibroblast growth factor (FGF), WNT, and Hedgehog (HH) pathways. We find that the attachment reaction is associated with a localized stromal induction of genes encoding BMP-2, FGF-2, and WNT-4. Despite efforts by many investigators, a simple in vitro model of implantation is not yet available to study either the hierarchy of the events triggered in the uterus by the embryo or the function of individual signaling proteins. We have therefore approached these questions by introducing beads loaded with purified factors into the receptive uterus. We show that beads soaked in HB-EGF or insulin-like growth factor-1 (IGF-1), but not other proteins, induce many of the same discrete local responses elicited by the blastocyst, including increased localized vascular permeability, decidualization, and expression of Bmp2 at the sites of the beads. By contrast, the expression domains of Indian hedgehog (Ihh), patched, and noggin become restricted as decidualization proceeds. Significantly, beads containing BMP-2 do not themselves elicit an implantation response but affect the spacing of implantation sites induced by blastocysts cotransferred with the beads.
Physical and Chemical Characteristics of Blast Furnace, Basic Oxygen Furnace, and Electric Arc Furnace Steel Industry Slags (2000)

Approximately 21 million tons of steel industry slag are produced each year in the United States, and many productive commercial uses of slag have been developed (e.g., road bed, fill material). However, because slag contains heavy metals at concentrations that are higher than in most soil, questions have been raised regarding the need to evaluate the potential human health and environmental hazards associated with current applications. To enhance general understanding of the physical and chemical characteristics of this material, slag samples from 58 active mills with blast furnaces, basic oxygen furnaces, and/or electric arc furnaces were examined. This study profiles the major and minor constituents of slag from each furnace type and reports the leachability of metals from slag under neutral and acidic conditions. Particle size distributions and partitioning coefficients (Kd) are also reported. Although concentrations of metals in slag are elevated relative to concentrations in soil, the metals in slag are tightly bound to the slag matrix and not readily leached. This study represents the most complete characterization of steel industry slag currently produced in North America, encompassing mills that collectively produce over 47% of steel industry slag. These data provide insights that may be useful for evaluating the marketability of steel industry slag and for human and ecological health risk assessment of environmental applications.
Synthesis of 5/7-, 5/8- and 5/9-bicyclic lactam templates as constraints for external β-turns (2005)

The 5/7-, 5/8- and 5/9-bicyclic lactams 3, 17, 5 and 6 have been synthesised as single diastereoisomers by a route involving ring closing olefin metathesis. The X-ray crystal structure of the amino acid hydrochloride has been carried out and compared to that of the saturated external beta-turn constraint 18.
Genetic Diversity among Common Bean Breeding Lines Developed for Central America (1995)

A study was undertaken to estimate the relative degree of genetic diversity among lines of common bean ( Phaseolus vulgaris L.) selected in Central America for BGMV resistance vs. lines that had no selection. Genetic distance (GD) based on the presence or absence of random amplified polymorphic DNA (RAPD) bands was estimated among breeding lines and cultivars of red and black beans. Another six black‐seeded cultivars from Brazil and Argentina were included for comparison. The multidimensional scaling plots revealed that the red and black beans in this study formed distinct clusters with no overlap. Based on consistency of marker frequencies within vs. between populations, reds and blacks were confirmed to be distinct populations. The mean RAPD marker diversity measured among lines selected for resistance was significantly less than that among unselected lines in reds (0.140 vs. 0.224) and blacks (0.170 vs. 0.223). Coeffecients of parentage (CP) were also utilized to estimate the relationships among selected and unselected lines. Selected lines displayed significantly larger CP than unselected lines in both reds (0.29 vs. 0.06***) and blacks (0.13 vs. 0.05***), reflecting closer genetic relationships and reduced diversity. Therefore, both molecular markers and CP indicated that selection for resistance had reduced genetic variability in both red and black beans. When CP were correlated with GD for reds, blacks, and all genotypes, correlations of −0.35***, −0.38***, and −0.36*** resulted, respectively. In spite of low correlation values, GD and CP presented similar tendencies. The choice of GD or CP as a measure of genetic relationship may depend on the quantity and quality of pedigree information available.
An improved etchback planarization process using a super planarizing spin-on sacrificial layer (2003)

Summary form only given. An improved process that uses a novel thermal flow/thermal setting polymer that can planarize even the largest geometries after a reflow at 200 degrees C is described. The planarization properties of this novel polymer were determined by coating it over 1.0- mu m step heights of different widths. The step heights over the line structure before and after the polymer coating were measured using a profilometer. A 1.2- mu m thick coating was used in these studies. The planarization etch was carried out in a reactive-ion-etching system. The etch rates of SiON depended weakly on the oxygen content, while the etch rates of the new organic material are a strong function of the oxygen content. Due to local loading effects, the etch rate ratio of the polymer to the CVD dielectric film cannot be maintained at a 1:1 ratio as measured by test wafers. In fact, the ratio has to be considerably less than 1 to give a planarized surface.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Microwave phased array sheet for wireless sensor network (2010)

We propose a novel architecture of a planar phased array antenna for wireless sensor network. The principle is based on wave scattering from distributed scatterers on a waveguide surface. Each scatterer radiates a portion of the incident guided wave in a location-dependent phase delay. Therefore, the directivity or the focus of the synthesized scattered wave can be tailored by tuning the spatial pattern of the scatterers. We also propose to fabricate electronically tunable scatterer pattern using semiconductor devices and verify the idea by simulation. Since it can be made in an extremely thin and light body at low cost compared to the conventional phased arrays, vast applications will be expected with respect to wireless sensor network.
The Fabrication of Grid Spacer Assemblies for Liquid-Metal Fast Breeder Reactors (1981)

Fabrication and welding methods used to make 217-rod grid spacers for liquid-metal fast breeder reactor application have been developed. Grid straps are formed from cold-worked Type 316 stainless-steel strip material and are assembled into a hexagonalshaped honeycomb grid, using resistance welding. A support strap is then welded onto the periphery of the grid using a manual gas tungsten arc welding (GTAW) process. The grids (11) are then located and appropriately spaced inside a hexagonal duct and attached using an automatic GTAW process. Three of these subassemblies have been completed and are awaiting loading of the fuel rods. After loading, the subassemblies are to be inserted in driver positions of the Fast Flux Test Facility for the acceptance test phase.
Long‐Term Variations in Optimal Programming of Cardiac Resynchronization Therapy Devices (2005)

The optimal follow-up and long-term programming of cardiac resynchronization therapy (CRT) devices are uncertain. The aim of this study was to quantify the temporal variations in programming parameters to optimize the follow-up of these devices. Before, during, and at specified intervals over 9 months after implant, 40 recipients of CRT devices were studied. At each visit, the patients were tested with a fixed sequence of stimulation parameters during echocardiographic and electrocardiographic (ECG) recordings. The optimal AV delay and inter-ventricular delays (V-V) were determined according to echocardiographic criteria. The echocardiographic data were, in turn, compared with the ECG recordings. Among the 40 patients, the optimal stimulation parameters remained unchanged throughout the follow-up in only three patients. In 18 patients, adjustments were required at each follow-up sessions. There was a trend toward reduction in the left ventricular (LV) predominance of the optimal V-V delay and an increase in the AV delay during follow-up. The mean optimal V-V delay at implant was 22 ms (-12 to +32 ms) with the LV activated first, versus 12 ms (-16 to +32 ms) at 9 months. The mean AV delay at implant was 115 ms versus 137 ms at 9 months. Individual changes could not be accurately predicted. The optimal stimulation parameters for CRT vary over time. Detailed, regular reevaluations, and reprogramming of optimal parameters may be appropriate.
Discs in cataclysmic variables and X-ray binaries (1989)

I review recent progress in the study of accretion discs in cataclysmic variables (CVs) and X-ray binaries. Observations of CVs, especially eclipse mapping, give detailed agreement with steady-state disc theory. Coronae and winds are probably universal features of discs in such systems. Our present ignorance of the disc viscosity is the main barrier to progress in understanding time dependence and stability properties. Non-axisymmetric structure is particularly prominent in observations of low-mass X-ray binaries. This may be caused by the interaction of the mass transfer stream from the companion star with the disc.

APP with Kunitz type protease inhibitor domain (KPI) correlates with neuritic plaque density but not with cortical synaptophysin immunoreactivity in Alzheimer's disease and non-demented aged subjects: a multifactorial analysis. (1995)

The formation of beta A4 amyloid protein in neuritic plaques in Alzheimer's disease (AD) and advanced age is a complex process that involves a number of both cellular and molecular mechanisms, the interrelations of which are not yet completely understood. We have examined quantitatively, in AD and aged controls an extended spectrum of amyloid plaque-related cellular and molecular factors and the cortical synaptophysin immunoreactivity (synaptic density) in order to check for interrelations between them by multifactorial analysis. In 3 cases of senile dementia of the Alzheimer type (SDAT) aged 72, 80 and 82 years, and 9 controls aged 43-88 (mean age 65) years, the cortical synaptophysin immunoreactivity was assessed, together with the numbers of neurons, astrocytes and microglial cells, senile plaques, of tangle-bearing neurons, and the amount of beta A4 amyloid precursor protein (APP) with and without the Kunitz type serine protease inhibitor (KPI) domain. The main results were: APP including the KPI domain (KPI-APP) correlated with the number of neuritic plaques, regardless of whether they occurred in SDAT or non-demented controls. There was no significant difference in the amount of KPI-APP between SDAT and controls. Conversely, APP695 (without KPI) was significantly reduced in SDAT. KPI-APP did not correlate with the synaptophysin immunoreactivity (RGVA), while APP695 showed a significant correlation with the latter in all evaluations. It also correlated with the neuron counts, which was not true for KPI-APP. These results support previous findings indicating that KPI-APP is an important local factor for amyloid deposition in the neuritic plaques, both in AD and in non-demented aged people. On the contrary, KPI-APP does not seem to be significantly involved in the mechanisms of synaptic change outside of the plaques.
A class ol qualitatively eobust estimates (1989)

We consider a wide class of estimates which present some formal analogy with The well-known L-estimates. We obtain the following results: The qualitative robustness is proved and the influence function is computed under mild conditions. A Theorem on asymptotic normality and asymptotic validity of FRECHET-CRAMER-RAO-bound is shown. A particular subclass of estimates is considered: the corresponding breakdown point is ootameci arm. some simulation results are given
A low distortion adaptive noise cancellation structure for real time applications (2005)

This paper describes an adaptive noise cancelling structure suitable for situations where the noise reference transducer is closely spaced relative to the primary transducer. The structure is based on two LMS delay line cancellers with cross coupled feedback. This structure is shown, under certain circumstances, to cancel noise with low signal distortion when the transmission paths between primary and secondary sensors have low attenuation and the primary signal is continuous. The system is shown to have an enhanced performance when the primary signal is intermittent and a signal energy detector is used.
Inhibition of human vitamin‐K‐dependent protein‐S‐cofactor activity by a monoclonal antibody specific for a Ca<sup>2+</sup>‐dependent epitope (1987)

Protein S is an anticoagulant vitamin-K-dependent plasma protein functioning as a cofactor to activated protein C in the degradation of factors Va and VIIIa. A murine monoclonal antibody, HPS 7, specific for a calcium-stabilized epitope in human protein S, is described. The epitope was available in intact protein S, both in its free form and when protein S was bound to C4b-binding protein. It disappeared upon reduction of disulfide bridges and also after thrombin of chymotrypsin cleavage of protein S. Thrombin cleaves protein S close to the calcium-binding region containing gamma-carboxyglutamic acid (Gla). The cleaved protein still contains the Gla region, linked by a disulfide bridge, but it has a lower affinity for calcium and no protein C cofactor activity. The thrombin-mediated cleavage of protein S could be inhibited by HPS 7. The Ka for the interaction between protein S and the monoclonal was estimated to be approximately 0.7 X 10(8) M-1. Half-maximal binding between HPS 7 and protein S was observed at a calcium concentration of 0.50 mM, indicating that saturation of the Gla region with calcium was required for the interaction. The recently reported Gla-independent high-affinity calcium binding did not induce the epitope. The calcium-dependent binding of protein S to phospholipid vesicles as well as the protein C cofactor activity was inhibited by HPS 7. The data suggests that the epitope for HPS 7 is located in the Gla region of protein S or in the closely positioned thrombin-sensitive region.
A new approach to detect and segment overlapping cells in multi-layer cervical cell volume images (2016)

Detection and segmentation of overlapping cell nuclei and cytoplasm in multi-layer Pap smear volumes are critical prerequisites for automatic screening of cervical cancer. The novel approach proposed here is an improved version of our top ranked method for the Segmentation of Overlapping Cervical Cells from Multi-layer Cytology Preparation Volumes Challenge — ISBI 2015. From the images provided of multiple focal planes through liquid-based Pap smear samples, nuclei within Extended Depth of Field (EDF) images are first located with an iterative approach and then clumps are segmented using a learned Gaussian mixture model by Expectation-Maximization (EM) algorithm from pixel intensities. The overlapping boundaries of cytoplasm on the multifocal planes are approximated using a new distance metric and then refined in two post-processing steps. Promising results with Dice Coefficient (0.861), False Negative object rate (0.352) and True Positive pixel rate (0.874) indicate that nuclei and their corresponding cytoplasm in highly overlapping cytology multi-layer Pap smear volumes can be effectively detected and segmented using this approach.
The Science of Respiration and the Doctrine of the Bodily Winds in Ancient India (1993)

The following historical and philological study traces the science of respiration and the doctrine of the bodily winds through ancient Indian religious and technical literature. Basic notions about respiration and bodily winds appear in the literature of the vedic samhitas and brahmanas. By the end of the principal upanisads these early ideas begin to be codified into two separate systems. One, emphasizing a physiology of bodily winds, reaches its traditional formulation in the classical medical literature of Ayurveda, the other, focusing on respiration, attains its classical formulation in Yoga. The two unite later, when Yoga integrates medical theory into its science of respiration. Asceticism is the common thread connecting the various stages in the development of respiration
Promoting Shared Prosperity in South Asia (2013)

The geography of poverty has changed. More than 70 percent of the world s poor live not in low-income countries, but in middle-income countries. In 2008, nearly 570 million people lived on less than US$1.25 a day in South Asia, compared to 385 million in sub-Saharan Africa. In addition, nearly 70 percent of the poor people in South Asia live in the lagging regions. Improving the living standards of these regions is crucial to achieving the goal of shared prosperity. Economic growth is not sufficient to enable the lagging regions of South Asia to catch up with the leading regions, in terms of proportional reductions in poverty rates. Policies must be specifically targeted toward achieving greater growth and poverty reduction in these regions. One particular policy channel to achieve shared prosperity is pro-poor fiscal transfers. For the most part, interstate fiscal transfers in South Asian countries do promote equity through transfer of resources to poorer regions, but this outcome usually occurs when pro-poor redistribution has explicit rules and transparency. Further, simply directing financial resources to lagging regions may not be sufficient, and may need to be complemented with increases in capacity, transparency, and participation to facilitate accountability at the local level. Policy makers need to boost shared prosperity and take another look at the millennium development goal paradigm. A new lens is needed- one that shifts the focus of policy from national to subnational level, and from leading to lagging regions, where poverty, gender disparity, and human misery are concentrated.
Calciseptine, a peptide isolated from black mamba venom, is a specific blocker of the L-type calcium channel. (1991)

The venom of the black mamba contains a 60-amino acid peptide called calciseptine. The peptide has been fully sequenced. It is a smooth muscle relaxant and an inhibitor of cardiac contractions. Its physiological action resembles that of drugs, such as the 1,4-dihydropyridines, which are important in the treatment of cardiovascular diseases. Calciseptine, like the 1,4-dihydropyridines, selectively blocks L-type Ca2+ channels and is totally inactive on other voltage-dependent Ca2+ channels such as N-type and T-type channels. To our knowledge, it is the only natural polypeptide that has been shown to be a specific inhibitor of L-type Ca2+ channels.
