Capturing the human figure through a wall (2015)

We present RF-Capture, a system that captures the human figure -- i.e., a coarse skeleton -- through a wall. RF-Capture tracks the 3D positions of a person's limbs and body parts even when the person is fully occluded from its sensor, and does so without placing any markers on the subject's body. In designing RF-Capture, we built on recent advances in wireless research, which have shown that certain radio frequency (RF) signals can traverse walls and reflect off the human body, allowing for the detection of human motion through walls. In contrast to these past systems which abstract the entire human body as a single point and find the overall location of that point through walls, we show how we can reconstruct various human body parts and stitch them together to capture the human figure. We built a prototype of RF-Capture and tested it on 15 subjects. Our results show that the system can capture a representative human figure through walls and use it to distinguish between various users.
Automatic Simplification of Obfuscated JavaScript Code: A Semantics-Based Approach (2012)

JavaScript is a scripting language that is commonly used to create sophisticated interactive client-side web applications. However, JavaScript code can also be used to exploit vulnerabilities in the web browser and its extensions, and in recent years it has become a major mechanism for web-based malware delivery. In order to avoid detection, attackers often take advantage of the dynamic nature of JavaScript to create highly obfuscated code. This paper describes a semantics-based approach for automatic deobfuscation of JavaScript code. Experiments using a prototype implementation indicate that our approach is able to penetrate multiple layers of complex obfuscations and extract the core logic of the computation, which makes it easier to understand the behavior of the code.
Influence of platelet size before coronary angioplasty on subsequent restenosis (1993)

Platelet size has been shown to reflect platelet activity. We prospectively measured the mean platelet volume (MPV) in 47 patients undergoing single vessel angioplasty for symptomatic angina. The patients underwent repeat angiography 4-8 months later irrespective of symptomatic status. Restenosis was assessed quantitatively by hand held calliper measurements of the lesion and qualitatively by a return of angina, ST segment changes on an exercise test and visual analysis of the lesion severity by two experienced angiographers. Twenty-four patients developed recurrent angina during the follow-up period, the MPV in the group with chest pain was 8.54 +/- 0.60 fl compared to 8.1 +/- 0.69 fl in the asymptomatic group (P = 0.04). Twenty two patients had significant ST segment changes at exercise. In this group the MPV was 8.6 +/- 0.56 fl compared to 8.0 +/- 0.70 fl for the group with a negative test (P = 0.002). Similarly visually assessed angiographic stenosis showed a significant increase in the restenotic group (8.6 +/- 0.56 vs. 8.0 +/- 0.61 fl, P = 0.001). The relative odds for developing clinically defined restenosis were 10.2 times greater if the pre-procedural MPV lay in the upper compared to the lowest quartile. There was a positive correlation between MPV and change in minimal luminal diameter between post angioplasty and follow-up angiography, assessed quantitatively, r = +0.56, P = 0.016. There was no association between clinical or angiographic definitions of restenosis and haemoglobin, red cell count, mean corpuscular volume, white cell count or platelet count. Platelet size may influence the development of restenosis after successful coronary angioplasty.
Forecasting Financial Distressed Companies in Taiwan by Using the Concept of the EBO Model (2006)

Financial distress has been an important topic in corporate governance. This study applies Edwards-Bell-Ohlson (EBO) model to forecast financial distress. Using the critical variables in the EBO model, we also apply Classification and Regression Tree (CART) to forecast. The decision tree is intended to provide a better idea of what impacts the financial distress. There are 36 listed companies in Taiwan Stock Exchange Corporation as the data sample. These data are further divided for in-sample estimation and out-of-sample forecasting. The in-sample data are used to establish a decision tree and to test the EBO model. The out-of-sample forecasting data are used to evaluate forecasting performance. The empirical results are compared to demonstrate the advantages of both the EBO model and the decision tree.
Anomaly Detection Using Optimally Placed <inline-formula> <tex-math notation="LaTeX">$\mu \text{PMU}$ </tex-math> </inline-formula> Sensors in Distribution Grids (2017)

As the distribution grid moves toward a tightly monitored network, it is important to automate the analysis of the enormous amount of data produced by the sensors to increase the operators situational awareness about the system. In this paper, focusing on microphasor measurement unit (μPMU) data, we propose a hierarchical architecture for monitoring the grid and establish a set of analytics and sensor fusion primitives for the detection of abnormal behavior in the control perimeter. Due to the key role of the μPMU devices in our architecture, an optimal μPMU placement with limited number of sensors is also described that finds the best location of the devices with respect to our rules. The effectiveness of the proposed methods are tested through the synthetic and real μPMU data.
<i>Blastocystis ratti</i>Induces Contact-Independent Apoptosis, F-Actin Rearrangement, and Barrier Function Disruption in IEC-6 Cells (2006)

Blastocystis is an enteric protozoan purportedly associated with numerous clinical cases of diarrhea, flatulence, vomiting, and other gastrointestinal symptoms. Despite new knowledge of Blastocystis cell biology, genetic diversity, and epidemiology, its pathogenic potential remains controversial. Numerous clinical and epidemiological studies either implicate or exonerate the parasite as a cause of intestinal disease. Therefore, the aim of this study was to investigate the pathogenic potential of Blastocystis by studying the interactions of Blastocystis ratti WR1, an isolate of zoonotic potential, with a nontransformed rat intestinal epithelial cell line, IEC-6. Here, we report that B. ratti WR1 induces apoptosis in IEC-6 cells in a contact-independent manner. Furthermore, we found that B. ratti WR1 rearranges F-actin distribution, decreases transepithelial resistance, and increases epithelial permeability in IEC-6 cell monolayers. In addition, we found that the effects of B. ratti on transepithelial electrical resistance and epithelial permeability were significantly abrogated by treatment with metronidazole, an antiprotozoal drug. Our results suggest for the first time that Blastocystis-induced apoptosis in host cells and altered epithelial barrier function might play an important role in the pathogenesis of Blastocystis infections and that metronidazole has therapeutic potential in alleviating symptoms associated with Blastocystis.
IgG-mediated down-regulation of IgE bound to mast cells: a potential novel mechanism of allergen-specific desensitization (2013)

Background Allergen-specific IgGs are known to inhibit IgE-mediated mast cell degranulation by two mechanisms, allergen-neutralization and engagement of the inhibitory FcγRIIB recruiting the phosphatase SHIP-1. Here we unravel an additional mechanism of IgG-mediated mast cell desensitization in mice: down-regulation of allergen-specific IgE. Methods Mast cells were loaded in vitro and in vivo with monoclonal IgE antibodies specific for Fel d1 and exposed to immune complexes consisting of Fel d1-specific IgG antibodies recognizing different epitopes. Down regulation of IgE was followed by flow cytometry. Results Mast cells loaded with 2 different IgE antibodies efficiently internalized the IgE antibodies if exposed to recombinant Feld d1. In contrast, no down-regulation occurred if mast cells were loaded with IgE antibodies exhibiting a single were before stimulation with recombinant Fel d1. Interestingly, however, IgEs of a single specificity were rapidly down-regulated in vitro and in vivo in the presence of Fel d1-specific monoclonal IgGs recognizing another epitope on Fel d1. Despite FceRI-internalization, little calcium flux or mast cell degranulation occurred. FcγRIIB played a dual role in the process since it enhanced IgE internalization and prevented cellular activation as documented by the inhibited calcium flux and mast cell degranulation. Similar observations were made in the presence of low concentrations of IgEs recognizing several epitopes on Fel d1. Conclusion We demonstrate here that Fel d1-specific IgG antibodies interact with FcγRIIB which (i) promotes IgE internalization; and (ii) inhibits mast cell activation. These results broaden our understanding of allergen-specific desensitization and may provide a mechanism for long-term desensitization of mast cells by selective removal of long-lived IgE antibodies on mast cells.
Long-Term Stability of Ni-YSZ Anode with a New Microstructure Prepared from Composite Powder (1999)

anodes with a new microstructure for solid oxide fuel cells were successfully prepared from composite powder. The composite powder consisting of fine YSZ particles dispersed on the surface of particles was synthesized by spray pyrolysis. The anodic polarization for cermet in which few small YSZ grains were dispersed preferentially on the surface of grains did not increase during of operation at . This fact suggests that a anode cermet having superior long‐ term stability can be prepared by this slurry method. ©1998 The Electrochemical Society
What is the cost of blindness? (2003)

Ideally an independent cost study based on the experiences of a cohort of elderly people with failing eyesight should be undertaken

Age related macular degeneration (AMD), particularly the wet variant, is an important cause of blindness and a serious public health challenge in older people. A recent health technology appraisal for the National Institute for Clinical Excellence (NICE) of a new treatment, photodynamic therapy for AMD, included the requirement to model the cost utility of treatment. (Cost utility analysis is a form of economic evaluation which compares the cost of two alternative interventions and their health outcomes expressed as a single index that combines length of life and quality of life. Cost utility is usually given as a cost per quality adjusted life year.)

In this it was necessary to include the costs averted by the treatment preventing people becoming blind.1 These are costs averted that the government would have spent supporting the blind person, such as visual rehabilitation, social services, or local authority care rather than the cost of blindness to the individual affected.2 Generating a cost of blindness is a generic feature of cost utility models of a variety of other treatments in similar eye conditions such as diabetic retinopathy.3,4 In these, the blindness cost estimate is often based on a 1990 US federal budgetary cost.5 This estimate for a blind person over retirement age was very low (US$32). Obviously it did not take into account other public expenditure so would have been inappropriate to a UK based health technology assessment more than 10 years later. Another approach taken when conducting cost utility analyses is to only include the cost of treatment and ignore the costs averted. This can be done if a “for profit” third party insurer perspective is taken, but again …
Dual Luciferase Assay for Secreted Luciferases Based on <i>Gaussia</i> and NanoLuc (2013)

Just recently, NanoLuc, a new engineered luciferase based on the small subunit of the luciferase from Oplophorus gracilirostris was introduced. Like the luciferase from Gaussia princeps, this luciferase is secreted into the medium. Both luciferases are the smallest and brightest luciferases known and well-suited for reporter assays. In our experiments, we demonstrate that both luciferases can be used together in a dual-reporter assay by solving the problem that NanoLuc produces a significant signal with coelenterazine, which is the substrate for Gaussia luciferase. We found that the background signal from NanoLuc with coelenterazine can be calculated from the determination of NanoLuc activity in the presence of its substrate furimazine. This in turn allows the precise determination of the activity of Gaussia which does not produce light in the presence of furimazine. Based on this observation, we developed a high sensitive dual secreted luciferase assay which allows the determination of both activities in a single cotransfection experiment. We demonstrate the versatility and robustness of the assay for the normalization of reporter gene activities. Since Gaussia luciferase and NanoLuc are nonhomologous reporters, the method to determine both luciferase activities may also be useful for coincidence reporter gene systems for high-throughput screening.
A GBAS Testbed to Support New Monitoring Algorithms Development for CAT III Precision Approach (2010)

The development of new monitoring algorithms needs to have access to a platform that offers flexibility, operational evaluation facilities, test and validation capacities. DLR’s GBAS test bed offers all these features with additional simulation capability. This paper illustrates these properties by showing an application of the recently developed absolute ionosphere gradient monitor by taking advantage of a network of three reference receivers located in the DLR’s research airport at Braunschweig. This paper presents a first draft of an absolute ionosphere gradient monitor capable of detecting gradients from 300 mm/km to 2000 mm/km in order to fulfill the GAST-D requirements in terms of ionospheric gradient monitoring for the ground subsystem. The three receivers give the possibility to build two independent Absolute Slant Ionosphere Gradient Monitors (ASIGM). The performances achieved depend on the performances of the receivers, their relative location and the orientation of their baselines with respect to the runway direction. ASIGM with baseline in the direction of the runway provide the best observability of an ionsphere gradient that a GBAS user can experience during the approach phase (for straight-in approaches). The smaller the angle between the runway and the considered monitor baseline is, the lower the uncertainty of the gradient in the direction of the runway. Distribution of receivers parallel to the runway provides the best observability conditions. This paper gives the optimal relative location of receivers in order to achieve 100% detectability in the 300 to 2000 mm/km range of the absolute slant ionosphere gradient. Two configurations were investigated: one with 3 and another one with 4 receivers linearly distributed. The results obtained are extremely promising for the GAST-D requirements fulfillment and the corresponding architectures can easily be implemented.
Efficient multi-segment message transmission with slot reuse on DQDB (1991)

A modification is presented of the distributed-queue dual-bus (DQDB) access protocol that allows: (1) messages to be transmitted with a minimal amount of overhead, and (2) slots to be released by the destination stations, without increasing the stations latencies, and without the use of erasure nodes. The allowance for a minimal overhead to be included in multi-segment message transmissions is provided through the use of the continuation-bit approach, while the slot release by destination stations, without increasing the stations latencies, is made possible by having stations keep track of the active message transmissions. This protocol requires few, but not major, changes to the slot format of the DQDB. The performance of the new protocol compares favourably to that of the original DQDB protocol and the DQDB protocol with erasure nodes.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Protein-inspired modified DNAzymes: dramatic effects of shortening side-chain length of 8-imidazolyl modified deoxyadenosines in selecting RNaseA mimicking DNAzymes (2011)

The discovery of imidazole/amine-functionalized DNAzymes that efficiently cleave RNA independently of divalent metal cations (M(2+)) and cofactors underscores the importance of expanding the catalytic repertoire with modified nucleosides. Considerable effort has gone into defining polymerase tolerances of various modified dNTPs for synthesizing and amplifying modified DNA. While long linkers are generally found to enhance incorporation and therefore increase sequence space, shorter linkers may reduce the entropic penalty paid for orienting catalytic functionality. Catalytic enhancement ultimately depends on both the functional group and appropriate linkage to the nucleobase. Whether a shorter linker provides enough catalytic enhancement to outweigh the cost of reduced polymerizability can only be determined by the outcome of the selection. Herein, we report the selection of DNAzyme 20-49 (Dz20-49), which depends on amine, guanidine, and imidazole-modified dNTPs. In contrast to previous selections where we used dA(ime)TP (8-(4-imidazolyl)ethylamino-2'-dATP), here we used dA(imm)TP (8-(4-imidazolyl)methylamino-2'-dATP), in which the linker arm is shortened by one methylene group. Although the most active clone, Dz20-49, was absolutely dependent on the incorporation of either dA(imm)p or dA(ime)p, it catalyzed cofactor independent self-cleavage with a rate constant of 3.1 ± 0.3 × 10(-3) min(-1), a value not dissimilar from unmodified catalysts and strikingly inferior to modified catalysts selected with dA(ime)TP. These results demonstrate that very subtle differences in modified nucleotide composition may dramatically effect DNAzyme selection.
[Emerging problems in enforcement of safe maternity and feeding protection at work: a public prevention service experience]. (2008)

We have examined the claims for advance maternity leave or prolonged benefits for breastfeeding addressed to Occupational Health Unity of Local Health Service 11 by women at harmful works in the period 2002-2005. The most frequent occupations were: shoemaker (29%), service company's employee (7%), tanners (7%), leather industry's employee (6%) and food industry's employee (6%). The most important risk factors were: bound postures, manual load handling, chemical hazards and biological agents. The numbers of claims increased during the period of interest. In the work place often risks for pregnancy and breastfeeding are not correctly assessed and women workers are not informed on their rights. The Occupational Health Unity of Local Health Service 11 tried to correct the lack of information for workers, employers, workers' representatives in health and safety and enterprise's occupational health physician.
Antioxidant and Anti-Inflammatory Activities of Protein Hydrolysates from <i>Mytilus Edulis</i> and Ultrafiltration Membrane Fractions (2014)

Multifunctional bioactive peptides from Mytilus edulis were produced by gastrointestinal digestion. The optimal conditions for production were determined at an enzyme/substrate ratio of 1:500 for 30 min hydrolysis time based on antioxidant and anti-inflammatory assays. Thus, peptides at 1:500 were further fractionated based on molecular weight. The <1 kDa peptide fraction exhibited 0.25 μg/mL of IC50 value with the highest activity against 2,2-diphenyl-1-picrylhydrazyl scavenging activity, but similar reducing power and 2,2-azino-bis(3-ethylbenzthiazoline)-6-sulfonic acid (ABTS+) radical scavenging activity were observed in all fractions. In the oxygen radical absorbance capacity assay, the 1–5 kDa peptide fraction exhibited the best oxygen radical absorbance capacity value by 430.8 μM trolox equivalent/mg of sample. In addition, the 1–5 kDa peptide fraction exhibited 58.74% of protection ability against hydroxyl radical-induced DNA damage. In the NO inhibition assay, the >5 kDa peptide fraction showed 92.35% inhibition activity. All peptide fractions are rich in antioxidant amino acids such as Glu, Asp and His. Practical Applications Most studies suggest that the consumption of shellfish promotes health. Shellfish is rich in bioactive compounds such as protein, carbohydrate, lipids and minerals. In this study, we produced bioactive peptides from M. edulis by gastrointestinal digestion, and further fractionated using ultrafiltration membrane. The present results indicated that the M. edulis hydrolysates and its fractions exhibited the potent antioxidant and anti-inflammatory activities, and these activities would be useful to improve human health.

Problem areas in computer security assessment (1977)

An important problem area in providing security in computer systems is to avoid excessively costly and constraining security practices while providing an adequate level of security. In addition, there are problems in determining an appropriate level of investment in techniques and practices which enhance security and in the measurement of returns on those investments, i.e., to what degree is security improved by any given technique?
