Parameter management schemes for cancelable biometrics (2011)

Protecting biometric information is a critical issue in biometric systems, since physical characteristics such as fingerprints, irises, face and vein patterns, cannot be changed or revoked like passwords. To address this issue, an authentication scheme called cancelable biometrics has been studied, in which the biometric features are transformed by a kind of encryption or one-way function and matched without restoring the original features. The transformation function is determined by a user-specific parameter, which plays a similar roll as an encryption key. To secure biometric features using the cancelable biometrics, the parameters have to be managed properly. In this paper, we review several naive schemes for parameter management and point out that they reduce the usability of authentication systems. Then we propose a novel parameter management scheme based on server-side parameter management and authentication protocols using one-time parameters and one-time templates. Our scheme makes it possible to realize a cancelable biometric authentication system with high usability and security.

Prognostic factors and long‐term survivorship in patients with recurrent or metastatic carcinoma of the head and neck (2004)

Clinical parameters and tumor cell differentiation appear to be strong pretreatment predictors of outcome in patients with carcinoma of the head and neck and should be considered in the design of future randomized trials. A small percentage of patients with recurrent head and neck carcinoma can achieve long-term survival.
Super resolution and optical properties of THz double row array based on inexpensive Glow Discharge Detector (GDD) pixels (2011)

The properties of terahertz (THz) radiation are well known. They penetrate well most non-conducting media; there are no known biological hazards, and atmospheric attenuation and scattering is lower than visual and IR radiation. Thus THz imaging is very attractive for homeland security, biological, space, and industrial applications Recently we have found experimentally that inexpensive miniature neon indicator lamp Glow Discharge Detectors (GDD) can be used as THz detectors. Based on the GDD we designed, constructed, and experimentally tested an 8×8 GDD array. In order to improve the performance and the resolution of the THz images a larger array is required. In this work we use a special double row 2×18 moving array detector. The 2×18 GDD array enables us to employ scanning method in order to obtain 36×36 pixel THz images. Furthermore, using this double row array it will be possible to employ super resolution methods. Optical properties such as optical transfer function and measurement of point spread function are presented, as well as first results for the 2×18 GDD array.
The exit of Trypanosoma cruzi from the phagosome is inhibited by raising the pH of acidic compartments. (1990)

The protozoan parasite Trypanosoma cruzi can infect many distinct mammalian cell types. The parasites enter cells through the formation of phagocytic vacuoles, but later are found free in the cytosol, where they multiply as amastigotes. Using transmission electron microscopy we found that within 2 h after infection 70% of the parasites, including examples of both mammalian forms (trypomastigotes and amastigotes), were inside partially disrupted vacuoles or free in the cytosol. We demonstrated that the pH of vacuoles containing recently interiorized parasites is acidic, through immunocytochemical localization of the acidotropic compound DAMP (18) in their interior. Increasing the vacuolar pH with chloroquine, ammonium chloride, methylamine, or monensin significantly inhibited the escape of the parasites into the cytosol. These results are compatible with the hypothesis that an acid-active hemolysin of T. cruzi (15) might be involved in the escape mechanism.
Linking research, policy and practice in welfare services and education in Norway (2010)

In Norway, links between research, policy and practice are in a process of development, with initiatives to both strengthen the knowledge base for evidence-based policy and practice and increase the demand for research-based interventions. Examples of these initiatives from the fields of mental health, education and child welfare are provided, including institutions for research and development and the implementation of evidence-based programmes. The initiatives are set in the context of some basic facts about Norway and its research system. The implications of ‘importing’ evaluated intervention programmes from other countries are discussed, and the relative merits of a ‘what works’ or broader approach to evidence-based policy and practice are assessed.
The Infinite Hierarchical Factor Regression Model (2009)

We propose a nonparametric Bayesian factor regression model that accounts for uncertainty in the number of factors, and the relationship between factors. To accomplish this, we propose a sparse variant of the Indian Buffet Process and couple this with a hierarchical model over factors, based on Kingman's coalescent. We apply this model to two problems (factor analysis and factor regression) in gene-expression data analysis.

Nanomaterials based electrochemical sensors for biomedical applications (2013)

A growing variety of sensors have increasingly significant impacts on everyday life. Key issues to take into consideration toward the integration of biosensing platforms include the demand for minimal costs and the potential for real time monitoring, particularly for point-of-care applications where simplicity must also be considered. In light of these developmental factors, electrochemical approaches are the most promising candidate technologies due to their simplicity, high sensitivity and specificity. The primary focus of this review is to highlight the utility of nanomaterials, which are currently being studied for in vivo and in vitro medical applications as robust and tunable diagnostic and therapeutic platforms. Highly sensitive and precise nanomaterials based biosensors have opened up the possibility of creating novel technologies for the early-stage detection and diagnosis of disease related biomarkers. The attractive properties of nanomaterials have paved the way for the fabrication of a wide range of electrochemical sensors that exhibit improved analytical capacities. This review aims to provide insights into nanomaterials based electrochemical sensors and to illustrate their benefits in various key biomedical applications. This emerging discipline, at the interface of chemistry and the life sciences, offers a broad palette of opportunities for researchers with interests that encompass nanomaterials synthesis, supramolecular chemistry, controllable drug delivery and targeted theranostics in biology and medicine.

Self-assembled GaAs/AlGaAs coupled quantum ring-disk structures by droplet epitaxy (2010)

The fabrication, by droplet epitaxy, of a class of quantum nanostructures characterized by a regular, nanometres high, flat disks with a diameter of hundreds of nanometres and a hole at the centre encircled by a ring a few nanometres high, is presented here. A detailed analysis of the growth kinetics performed via in situ and ex situ probes allows us to propose a working model for the formation of these structures.
Monoclonal antibodies detect monocyte/macrophage activation and differentiation antigens and identify functionally distinct subpopulations of human rheumatoid synovial tissue macrophages. (1991)

Monoclonal antibodies (MAbs) to functionally heterogeneous populations of human rheumatoid arthritis (RA) synovial tissue macrophages and lipopolysaccharide (LPS)-activated U937 cells were generated. These MAbs were used to characterize macrophages in situ in the synovial pannus and to study relative antigen expression on the surface of cells isolated from the synovium and from normal peripheral blood. Monoclonal antibody 3D8, an anti-CD13 MAb, reacts with an antigen expressed on the surface of blood monocytes and is a monocyte activation-related antigen that is upregulated by exposure of monocytes to interferon-gamma (IFN-gamma) and LPS. The expression of the 3D8 antigen increases in parallel with MHC class II antigen expression and also is upregulated in culture as monocytes mature to macrophages. 3D8 antigen is expressed strongly on RA synovial tissue lining cells, which are thought to be composed of macrophages. 8D7 antigen expression, detected by MAb 8D7, increases on blood monocytes on cellular activation with LPS and interferon-gamma, but in contrast to the 3D8 antigen, does not increase with monocyte maturation in vitro. The 8D7 antigen is expressed differentially on density-defined macrophage subpopulations isolated from RA synovial tissue and is expressed more strongly on macrophages that are nonangiogenic than those that are angiogenic.
Vacuum Deposition by High-Energy Laser with Emphasis on Barium Titanate Films (1969)

A laser beam capable of energy outputs up to 500 Joule was directed through a glass window into a vacuum system onto fine grain powder of Cr, W, Ti, C, Sb2S3, ZnS, SrTiO3, and BaTiO3. A neodymium-doped glass laser of 1.06-μ wavelength was mostly used without Q spoiling. Sometimes the beam was focused. Films up to 2000 Å were achieved on glass with one laser burst only, which corresponds to deposition rates of up to 106 Å/sec. The substrate was positioned between the vapor source and laser so that the laser beam passed through it, and therefore, also served as a shield. Electron micrographs were taken. From electron transmission diffraction patterns it appeared as if BaTiO3 had not been decomposed. In order to evaluate electrical properties of the films, platinum-rhodium films were sputtered or “laser-deposited” onto glass slides to serve as base electrode. Then a barium titanate film was evaporated with a laser. On top of this, an array of thin aluminum dots were evaporated through a mask, so that it was possible to investigate different areas of the films. Values of up to 2.5 μF/cm2 at 1 kHz and relative dielectric constants of up to 1000 were measured. Dissipation factors were in a range from 1%–10%. The capacitance at 1 kHz was constant within 0.1% between 50 ° and 105 °C as well as above 160 °C. A sharp peak of the temperature dependence curve could be observed at about 125 °C where the capacitance increased by 30%. For most films the onset of breakdown was observed at a field strength of around 5×105 Vcm−1. Both the capacitance and dissipation factor decrease almost linearly when increasing the frequency from 60 Hz to 500 kHz with the capacitance reaching 90% of its 60-Hz value.
Crowdsourcing User-Generated Mobile Sensor Weather Data for Densifying Static Geosensor Networks (2017)

Static geosensor networks are comprised of stations with sensor devices providing data relevant for monitoring environmental phenomena in their geographic perimeter. Although early warning systems for disaster management rely on data retrieved from these networks, some limitations exist, largely in terms of insufficient coverage and low density. Crowdsourcing user-generated data is emerging as a working methodology for retrieving real-time data in disaster situations, reducing the aforementioned limitations, and augmenting with real-time data generated voluntarily by nearby citizens. This paper explores the use of crowdsourced user-generated sensor weather data from mobile devices for the creation of a unified and densified geosensor network. Different scenario experiments are adapted, in which weather data are collected using smartphone sensors, integrated with the development of a stabilization algorithm, for determining the user-generated weather data reliability and usability. Showcasing this methodology on a large data volume, a spatiotemporal algorithm was developed for filtering on-line user-generated weather data retrieved from WeatherSignal, and used for simulation and assessment of densifying the static geosensor weather network of Israel. Geostatistical results obtained proved that, although user-generated weather data show small discrepancies when compared to authoritative data, with considerations they can be used alongside authoritative data, producing a densified and augmented weather map that is detailed and continuous.
A Discussion of Zero Spring Rate Mechanisms Used for the Active Isolation Mount Experiment (1999)

In the summer of 1995 the Structural Dynamics Branch at NASA Langley Research Center set out to conceive a small, lightweight, low frequency isolation mount that could be used for spaceflight experiments. The Engineering Design Branch undertook the task of developing the isolation mount. This report describes the engineering process that led to three phases of a study entitled "Active Isolation Mounts" (AIM). A zero spring rate mechanism was used to achieve low fundamental frequencies for a payloads in the 1 to 10 pound range. It worked by balancing both a positive and a negative stiffness so that the net result was a small positive stiffness. The study demonstrated devices that could reduce the initial corner frequency by a factor of six for brief periods and a factor of two for extended periods. The designs were relatively simple and minimized weight, volume, and power. They could be scaled down and they were made of spaceflight compatible materials. All designs offered the ability to continuously vary the fundamental frequency. Yet, the goal of reducing the frequency by an order of magnitude was not achieved because the systems were too unstable at low frequencies. There was a trade between performance and stability.

Kalman-Consensus Filter : Optimality, stability, and performance (2009)

One of the fundamental problems in sensor networks is to estimate and track the state of targets (or dynamic processes) of interest that evolve in the sensing field. Kalman filtering has been an effective algorithm for tracking dynamic processes for over four decades. Distributed Kalman Filtering (DKF) involves design of the information processing algorithm of a network of estimator agents with a two-fold objective: (1) estimate the state of the target of interest and (2) reach a consensus with neighboring estimator agents on the state estimate. We refer to this DKF algorithm as Kalman-Consensus Filter (KCF). The main contributions of this paper are as follows: (i) finding the optimal decentralized Kalman-Consensus filter and showing that its computational and communication costs are not scalable in n and (ii) introducing a scalable suboptimal Kalman-Consensus Filter and providing a formal stability and performance analysis of this distributed and cooperative filtering algorithm. Kalman-Consensus Filtering algorithm is applicable to sensor networks with variable topology including mobile sensor networks and networks with packet-loss.
Millimeter-wave imaging system for personnel screening: scanning 10^7 points a second and using no moving parts (2006)

In this talk we describe the second version of our novel millimeter wave imaging system. This system is an active coherent system, working at 24GHz, and using planar programmable RF-lens. The system is capable of producing realtime movies without processing latency. Moreover, due to the planar nature of the lens, and its compact form, the footprint of the system is very small. The fact that it is monochromatic assures minimal spectral occupancy resulting in an imaging system well suited to personnel screening. The RF-lens, which lies at the heart of the proposed system, is a passive RF element, capable of focusing RF energy into small volumes within its field of view through a mechanism that changes the phase of the impinging wave on the lens-surface. This enables one to scan image voxels (volume pixels) in front of the lens. Since the phase change can be rapidly switched electronically, more than 10^7 voxels are scanned per second. We will discuss the reasons that lead us to develop this second system, the improvements that were made, and the overall enhancements to the system performance. For example, we will discuss the changes that enable us to go to higher frame rate.

This paper presents a design environment that integrates modelling through analytical and discrete event simulation and a knowledge based system that helps in the design, implementation, and maintenance of distributed systems based on local area networks. We present the background to why such an environment is required and gives a comparison with related efforts. This is followed by a description of the system itself. We present the lessons learned and difficulties encountered, and how far we have gone in implementation as well as future plans.
