An ensemble approach for increased anomaly detection performance in video surveillance data (2009)

The increased societal need for surveillance and the decrease in cost of sensors have led to a number of new challenges. The problem is not to collect data but to use it effectively for decision support. Manual interpretation of huge amounts of data in real-time is not feasible; the operator of a surveillance system needs support to analyze and understand all incoming data. In this paper an approach to intelligent video surveillance is presented, with emphasis on finding behavioural anomalies. Two different anomaly detection methods are compared and combined. The results show that it is possible to best increase the total detection performance by combining two different anomaly detectors rather than employing them independently.
Activity Recognition using Visual Tracking and RFID (2005)

Computer vision-based articulated human motion tracking is attractive for many applications since it allows unobtrusive and passive estimation of people's activities. Although much progress has been made on human-only tracking, the visual tracking of people that interact with objects such as tools, products, packages, and devices is considerably more challenging. The wide variety of objects, their varying visual appearance, and their varying (and often small) size makes a vision-based understanding of person-object interactions very difficult. To alleviate this problem for at least some application domains, we propose a framework that combines visual human motion tracking with RFID based object tracking. We customized commonly available RFID technology to obtain orientation estimates of objects in the field of RFID emitter coils. The resulting fusion of visual human motion tracking and RFID-based object tracking enables the accurate estimation of high-level interactions between people and objects for application domains such as retail, home-care, workplace-safety, manufacturing and others

Persistent Airway Hyperresponsiveness and Histologic Alterations after Chronic Antigen Challenge in Cats (1995)

We studied the effect of chronic immune sensitization on the airway reactivity and associated cytologic and histologic alterations in initially nonatopic cats, a species that spontaneously develops idiopathic asthma. Seven cats were sensitized by intramuscular injection of Ascaris suum antigen (AA) for 4 wk, and four other cats served as sham controls. Airway sensitization was demonstrated by an increased response to nebulized AA in sensitized animals (RL = 45.9 +/- 6.1 cm H2O/L/s, versus a baseline response of 24.7 +/- 1.5 cm H2O/L/s, p < 0.01), and hyperresponsiveness was demonstrated by an increased response to acetylcholine (ACh)-challenge 24 h after AA (approximately 1.0 log decrease in PD200, p < 0.01). The number of eosinophils in the sensitized animals' bronchoalveolar lavage (BAL) fluid increased 12-fold (p < 0.01 versus control) in response to AA challenge; 32 +/- 5% of the BAL eosinophils had a specific density < 1.050, versus 8 +/- 2% prior to AA challenge (p < 0.05). There was no change in airway reactivity, eosinophil recovery, or density in the control group 24 h after sham challenge with saline. The same seven sensitized cats further received nebulized AA three times weekly for 4 to 6 wk, after which BAL samples were again obtained and ACh dose-response curves generated 72 h after the final administration of nebulized AA. Airway hyperresponsiveness increased (approximately 1.5 log decrease in PD200, p < 0.001) and the number of eosinophils recovered in BAL fluid was increased 11-fold (p < 0.05). Necropsy specimens demonstrated bronchoconstriction in AA-challenged animals but not controls; luminal narrowing was accompanied by: (1) a 29.0 +/- 0.34% increase in smooth-muscle thickness (p < 0.05); (2) goblet-cell and submucosal-gland hypertrophy and hyperplasia; and (3) epithelial erosion and eosinophilic infiltration. We demonstrate in nonhuman species persistent airway hyperreactivity associated with a complete constellation of histologic changes in epithelium, smooth muscle, and mucus glands, and cytologic changes in BAL fluid, all induced by immune sensitization. Our data suggest that chronic immune sensitization per se could be a salient factor in causing many of the changes associated with chronic bronchial asthma.
FRET Enhancement in Multilayer Core−Shell Nanoparticles (2009)

This study describes the preparation and characterization of novel multilayer core-shell nanoparticles displaying metal-enhanced Forster resonant energy transfer. The increase in range and efficiency of Forster resonant energy transfer in these fluorescent nanocomposites and their vastly improved luminosity make them promising optical probes for a variety of applications such as cell imaging and biosensing.

Portugal (2014)

Inequality in Portugal increased between 1989 and 1994, and remained relatively unchanged until the mid-2000s. Then starting in 2005 there was a significant reduction in inequality, mainly due to the successful social policies aimed at reducing poverty and the expansion of the welfare state. The year 2009 was a new turning point: the deep economic crisis and the policies adopted have led to a new increase in inequality, as indicated by the increase in the Gini coefficient in 2010. We find that earnings inequality is one of the main drivers of household inequality, whereas educational attainment plays an important role in its future reduction. Furthermore, the co-existence between high levels of inequality and real income growth, between an improvement in social policies and the reduction of poverty, makes it more difficult to establish a clear causal relationship between inequality and the different dimensions of the Portuguese social, political, and cultural reality.
Light scattering and domain structure of ferroelectric PLZT family ceramics (1995)

Abstract Transparent ferroelectric PLLZT ceramics were prepared by partial substitution of (La0.5Li.5) complex ions for Pb ones in Pb(Zr,Ti)O3. Chemical formula of the ceramics is presented as [Pb1 − x (La0.5Li0.5) x ] (Zr x Ti1 − x )O3. In the range of 0 <x < 0.6, the ferroelectric properties were similar to those of PLZT. Light scattering was induced by discontinuous refractive index at boundaries such as domain walls and crystal grains in the ceramics. The intensity of scattered light was dependent on the average grain size and the direction of electric polarization. Biasing field and frequency dependence of the dielectric constant was explained by 180[ddot] domain reverse and 90[ddot] domain rotation. The dc bias field dependence of effective birefringence was also discussed. Key Words: Light scatteringbirefringence180° and 90° domainsdielectric constantpolarization
Wavelength-tunable and white-light emission from polymer-converted micropixellated InGaN ultraviolet light-emitting diodes (2006)

We report the use of light-emitting conjugated polymer materials to wavelength-convert the emission from a two-dimensional array of micropixellated InGaN light-emitting diodes (LEDs). We demonstrate hybrid organic/inorganic light-emitting devices that can operate across the entire visible spectrum, and we also fabricate white-emitting versions of these devices by employing single layers of carefully adjusted polymer blends in which cascade non-radiative energy transfer occurs between the constituent materials. Additional colours may be easily obtained by tuning the composition of the polymer blends. Our work demonstrates that the combination of conjugated polymers and UV micro-LED arrays provides an attractive approach to developing microscale wavelength-tunable light sources and may provide a route to low-cost full-colour microdisplays and other instrumentation devices.
Oxidation of Starch by Hydrogen Peroxide in the Presence of UV Light‐Part II (1972)

Abstract Various reaction variables in the hydrogen peroxide oxidation of starch in the presence of UV light have been investigated. Higher carboxyl and carbonyl contents of oxystarches were obtained under acidic than under alkaline conditions. Extent of oxidation was found to increase with time. Increasing the concentration of hydrogen peroxide results in an increase in the carboxyl and carbonyl contents. Apparently, air has no effect on the degree of oxidation whereas, oxygen seems to accelerate it.
15.1: High‐Resolution Integrated a‐Si Row Driver Circuits (2005)

Abstract A 12.1″ tablet panel with integrated a‐Si row driver circuits has been developed using a standard TFT process and an advanced FFS technology. XGA‐resolution 768‐stage shift register circuit with 2‐phase clocks has been elaborately designed and fabricated. We have optimized circuit parameters in order to obtain a highly reliable a‐Si row driver circuit structure.
Isolation of<i>Juniperus phoenicea</i>Volatiles by Supercritical Carbon Dioxide Extraction and Bioactivity Assays (2004)

Abstract By means of a supercritical fluid extractor, extract of Juniperus phoenicea L. was obtained in a single extraction stage. The yield was 0.2% by mass. The operative conditions were: extractor, pressure, P = 90 bar and temperature, T = 50°C; first separator, P = 90 bar and T = −10°C; second separator, P = 15 bar and T = 10°C. The hydrodistilled oil gave a yield of 0.3% by mass. In both extracts, the three compounds present in the biggest quantity were: α-pinene (18.4 versus 13.9% in the SFE and HD oil, respectively), germacrene D (14.3 versus 8.1%) and β-caryophyllene (8.7 versus 5.4%). The extracts obtained at different pressures were tested for antiviral, antiproliferative and antimicrobial activities. The results showed that the extracts obtained at 200 and 300 bar were cytotoxic against different cell lines and were active against a single-stranded RNA+ virus. The extracts containing the most cytotoxic active principles showed also antiproliferative activity against a panel of human cell lines derived from liquid and solid tumors. When tested for antimicrobial activity none of the samples resulted active.
Vapor-cooled lead and stacks thermal performance and design analysis by finite difference techniques (1985)

Investigation of the combined thermal performance of the stacks and vapor-cooled leads for the Mirror Fusion Test Facility-"B" (MFTF-B) (Figure 1) demonstrates considerable interdependency. For instance, the heat transfer to the vapor-cooled lead (VCL) from warm bus heaters, environmental enclosure, and stack is a significant additional heat load to the joule heating in the leads, proportionately higher for the lower current leads that have fewer current-carrying, counter flow coolant copper tubes. Consequently, the specific coolant flow (G/sec-kA-lead pair) increases as the lead current decreases. The definition of this interdependency and the definition of necessary thermal management has required an integrated thermal model for the entire stack/VCL assemblies.

Microneedle delivery of trivalent influenza vaccine to the skin induces long-term cross-protection (2016)

A painless self-immunization method with effective and broad cross-protection is urgently needed to prevent infections against newly emerging influenza viruses. In this study, we investigated the cross-protection efficacy of trivalent influenza vaccine containing inactivated A/PR/8/34 (H1N1), A/Hong Kong/68 (H3N2) and B/Lee/40 after skin vaccination using microneedle patches coated with this vaccine. Microneedle vaccination of mice in the skin provided 100% protection against lethal challenges with heterologous pandemic strain influenza A/California/04/09, heterogeneous A/Philippines/2/82 and B/Victoria/287 viruses 8 months after boost immunization. Cross-reactive serum IgG antibody responses against heterologous influenza viruses A/California/04/09, A/Philippines/2/82 and B/Victoria/287 were induced at high levels. Hemagglutination inhibition titers were also maintained at high levels against these heterogeneous viruses. Microneedle vaccination induced substantial levels of cross-reactive IgG antibody responses in the lung and cellular immune responses, as well as cross-reactive antibody-secreting plasma cells in the spleen. Viral loads in the lung were significantly (p < 0.05) reduced. All mice survived after viral challenges. These results indicate that skin vaccination with trivalent vaccine using a microneedle array could provide protection against seasonal epidemic or new pandemic strain of influenza viruses.
Reductive Ligation Mediated One-Step Disulfide Formation of <i>S</i>-Nitrosothiols (2010)

A one-step reductive ligation mediated disulfide formation of S-nitrosothiols was developed. This reaction involves the reaction of the S-nitroso group with phosphine-thioesters to form sulfenamide and thiolate intermediates, which then undergo a fast intermolecular disulfide formation to form stable conjugates. This reaction can be used to design new biosensors of S-nitrosated proteins.
SPONTANEOUS SELF-PULSING AND CAVITY DUMPING IN A CO2 LASER WITH ELECTRO-OPTIC <i>Q</i>-SWITCHING (1969)

Spontaneous self-pulsing has been observed in a 10.6-μ CO2 laser, Q-switched in ≈10 nsec by an internal GaAs electro-optic cell, with no saturable absorber present. Each Q-switched event consists of a train of ten or more 20-nsec pulses with a total duration of ≈400 nsec in a single P(20) line. Electro-optic dumping of the cavity energy near the peak of oscillation gives a single output pulse of ≈10-kW peak power and 25-nsec duration. A numerical comparison is made with the circulating π pulse theory of spontaneous pulsing.

Origins of genes: "big bang" or continuous creation? (1992)

Many protein families are common to all cellular organisms, indicating that many genes have ancient origins. Genetic variation is mostly attributed to processes such as mutation, duplication, and rearrangement of ancient modules. Thus it is widely assumed that much of present-day genetic diversity can be traced by common ancestry to a molecular "big bang." A rarely considered alternative is that proteins may arise continuously de novo. One mechanism of generating different coding sequences is by "overprinting," in which an existing nucleotide sequence is translated de novo in a different reading frame or from noncoding open reading frames. The clearest evidence for overprinting is provided when the original gene function is retained, as in overlapping genes. Analysis of their phylogenies indicates which are the original genes and which are their informationally novel partners. We report here the phylogenetic relationships of overlapping coding sequences from steroid-related receptor genes and from tymovirus, luteovirus, and lentivirus genomes. For each pair of overlapping coding sequences, one is confined to a single lineage, whereas the other is more widespread. This suggests that the phylogenetically restricted coding sequence arose only in the progenitor of that lineage by translating an out-of-frame sequence to yield the new polypeptide. The production of novel exons by alternative splicing in thyroid receptor and lentivirus genes suggests that introns can be a valuable evolutionary source for overprinting. New genes and their products may drive major evolutionary changes.
Selective MR imaging of labeled human peripheral blood mononuclear cells by liposome mediated incorporation of dextran‐magnetite particles (1993)

Human peripheral blood mononuclear cells (PBMCs) were incubated with large unilamellar vesicles (LUV) containing encapsulated dextran-magnetite particles (DMP). This resulted in an efficient incorporation of DMP. Electron microscopy revealed the presence of DMP in cells mainly in phagosomes and secondary lysosomes. DMP-labeled PBMCs showed a strong increase of the transverse relaxation rate (up to 16.6 s-1 for 5 x 10(7) cells/ml) and, accordingly, a great loss of signal intensity in MR imaging. The fraction of DMP containing PBMCs could be enriched by magnetic cell separation. The major population of the DMP containing cells proved to be monocytes. When PBMCs depleted of monocytes were used for labeling, DMP uptake was observed also in the peripheral blood lymphocytes. The labeling of PBMCs presented here may be used in future studies of selective MR imaging of in vivo cell migration in a variety of immunologically compromised tissue states, e.g., tumors, transplantations, and abscesses.
Role of transforming growth factor β1 in microvascular endothelial cell apoptosis associated with thrombotic thrombocytopenic purpura and hemolytic‐uremic syndrome (2001)

Primary human microvascular endothelial cells (MVEC) of restricted lineage undergo apoptosis when exposed to plasma from patients with thrombotic thrombocytopenic purpura (TTP) and sporadic hemolytic-uremic syndrome (HUS). This reflects the pathology and tissue distribution of lesions in vivo. As extracellular matrix (ECM) is critical to MVEC survival, and cytokines which regulate ECM, such as transforming growth factor (TGF)-β1, have been reported anecdotally to be altered in TTP/HUS, we examined the role of TGF-β1 and two ECM proteins, fibronectin and thrombospondin (TSP), in these disorders. Levels of active TGF-β1 were elevated in acute but not convalescent phases of TTP/sporadic HUS, as well as TTP associated with human immunodeficiency virus infection and use of the anti-platelet drug ticlopidine. MVEC from tissues susceptible to TTP-mediated apoptosis showed little active TGF-β1 production when exposed to TTP plasmas. In contrast, pulmonary MVEC and large-vessel EC, which are resistant to TTP-linked pathology, showed marked induction of TGF-β1 following TTP plasma exposure. Exogenous TGF-β1 suppressed TTP plasma-mediated apoptosis in susceptible MVEC in association with blockade of cell entry into S phase. Soluble TSP, devoid of detectable bound TGF-β1, had a similar effect, which paralleled its ability to induce TGF-β1 production in MVEC. In vivo, TSP deposition was diminished markedly in involved tissues of TTP patients. These data highlight the role of TGF-β1 and ECM in TTP and suggest that differential production of TGF-β1 by MVEC may play a role in their sensitivity or resistance to TTP/sporadic HUS-mediated apoptosis in vitro and in vivo.

RF CMOS fully-integrated heterodyne front-end receivers design technique for 5 GHz applications (2004)

This paper presents an architecture that allows the implementation of fully integrated heterodyne 5GHz RF receivers. The front-end circuitry consists of a low noise amplifier, a critical cascade of two notch filters, an active mixer, and a voltage controlled oscillator. The notch filters, which use on chip inductor Q-factor enhancement techniques, are designed to provide a wide bandwidth of image rejection (IR), eliminating the need for accurate IR tuning circuitry. More than 40dB of image rejection can be obtained in a standard 0.18/spl mu/m CMOS technology, for a 400MHz bandwidth centered at 7.2GHz, without having to resort to the overhead and the complexity of automatic tuning circuits. Design issues of homodyne and heterodyne 5GHz front-end receivers are received and discussed.
Patients with multiple myeloma treated with thalidomide: evaluation of clinical parameters, cytokines, angiogenic markers, mast cells and marrow CD57+ cytotoxic T cells as predictors of outcome (2007)

Our findings support the suggestion that thalidomide has anti-angiogenic and immunomodulatory effects in myeloma. The preferred method for assessing angiogenesis is plasma VEGF levels and the assessment of CD57+ cells for patients with myeloma receiving novel immunomodulatory drugs should be further investigated.
Rapid, Low-Temperature Amidation of Ethyl Cyano-Acetate with Lithium Amides Derived from primary and Secondary Amines (1990)

Keizai: An Interactive Cross-Language Text Retrieval System (2000)

Can we expect people to be able to get information from texts in languages they cannot read? In this paper we review two relevant lines of research bearing on this question and will show how our results are being used in the design of a new Web interface for cross-language text retrieval. One line of research, &quot;Interactive IR&quot;, is concerned with the user interface issues for information retrieval systems such as how best to display the results of a text search. We review our current research, on &quot;document thumbnail&quot; visualizations, and discuss current Web conventions, practices and folklore. The other area of research, &quot;Cross-Language Text Retrieval&quot;, is concerned with the design of automatic techniques, including Machine Translation, to retrieve texts in languages other than the language of the query. We review work we have done concerning query translation and multilingual text summarization. We then describe how these results are being applied and extended in t...
