Crowdsourced Traffic Event Detection and Source Reputation Assessment Using Smart Contracts (2019)

Real-time data about various traffic events and conditions-offences, accidents, dangerous driving, or dangerous road conditions-is crucial for safe and efficient transportation. Unlike roadside infrastructure data which are often limited in scope and quantity, crowdsensing approaches promise much broader and comprehensive coverage of traffic events. However, to ensure safe and efficient traffic operation, assessing trustworthiness of crowdsourced data is of crucial importance; this also includes detection of intentional or unintentional manipulation, deception, and spamming. In this paper, we design and demonstrate a road traffic event detection and source reputation assessment system for unreliable data sources. Special care is taken to adapt the system for operation in decentralized mode, using smart contracts on a Turing-complete blockchain platform, eliminating single authority over such systems and increasing resilience to institutional data manipulation. The proposed solution was evaluated using both a synthetic traffic event dataset and a dataset gathered from real users, using a traffic event reporting mobile application in a professional driving simulator used for driver training. The results show the proposed system can accurately detect a range of manipulative and misreporting behaviors, and quickly converges to the final trust score even in a resource-constrained environment of a blockchain platform virtual machine.
14세기 동기(銅器)의 유행과 그 의미: 고려시대 분묘 유적을 중심으로 (2011)

14세기 고려청자에 주목할 만한 변화가 발생했다. 간지명 청자의 등장, 도식화된 문양 등은 청자 변화의 구체적 내용이었다. 청자 변화의 원인은 주로 생산체계의 변화에 따른 대량생산과 소비의 확대로 이해되었다. 그러나 최근 고려분묘에 대한 조사와 연구에 의하면, 14세기 들어 청자의 출토량은 이전시기와 감소하거나 큰 변동은 없다. 대량생산에도 불구하고 분묘에서의 소비는 크게 증가하지 않은 것이다. 이에 본 연구는 고려시대 분묘 유적의 출토품을 검토하였다. 지역성과 시기를 고려해 상주 청리, 청주 용암, 진안 수천리, 부산 덕천동, 안산 대부도 육곡, 단양 현곡리, 경주 검단리, 청도 대전리, 고양 더부골 고려 분묘 유적을 조사하여 다음과 같은 결론을 내릴 수 있었다. 첫째, 같은 시기라고 하더라도 지역에 따라 청자가 주로 출토되는 지역과 청동기가 비교적 다수 출토된 지역이 있었다. 상주 청리는 청자만 주로 출토된 반면, 청주 용암유적에서는 다수의 동기가 출토되었다. 이러한 차이는 지역적 차이일 가능성이 높다. 둘째, 지역적 차이에도 불구하고 전체적으로 11~13세기 중반까지 분묘의 부장품에는 청자가 다수를 차지하고 동합·동발·동접시 등이 공반 출토되고 있었다. 셋째, 13세기 후반 이후 동기의 출토가 급증하였다. 14세기로 편년되는 분묘에서는 청자와 함께 다수의 청동기가 공반 출토되고 있었다. 따라서 분묘의 출토양상에 의하면 14세기에는 동기가 유행하였다. 당시 동기의 유행은 문헌을 통해서도 확인할 수 있다. 홍자번의 상소 등 여러 문헌에 의하면, 원간섭기 고려에서는 동기가 상당히 유행하고 있었다. 한편 동기 확산의 배경에는 중국 화폐제도의 변화와 지배층의 취향이 자리 잡고 있었다. 원은 고래의 銅錢을 기축화폐로 사용하지 않고 은으로 지불 보증된 보초를 기축화폐로 삼았다. 기축화폐의 변화는 동을 다른 용도로 사용할 수 있도록 허락했다. 그 결과 이전보다 자유롭게 동을 이용해 동기 혹은 銅像을 주조할 수 있게 되었다. 물질적 배경이외에 문화적 변화도 있었다. 새롭게 중국의 지배층이 된 몽고족은 유목민의 전통에 따라 자기보다는 금속기를 선호했고 고려 역시 이 영향으로부터 자유로울 수 없었다. 이런 분위기에서 고려에서는 자기가 아닌 동기를 선호하게 되었던 것이다. 그리고 이것이 자기 산업의 쇠퇴와 자기의 질 하락을 가져온 한 배경이었을 것이다.
β-Glycosidase Activity toward Different Glycosidic Forms of Isoflavones (2005)

Isoflavones, a group of soybean components that significantly contribute to human health and disease prevention, exist in various chemical forms. The enzyme activity can be very sensitive to molecular structure; thus, the profile of the isoflavones can affect their rate of hydrolysis. The objective of this work was to study the beta-glycosidase activities toward isoflavone beta-glycosides and their conjugated forms. Hydrolysis experiments were conducted where beta-glycosides and their conjugates were treated with beta-glycosidase. Results confirmed that beta-glycosidase can hydrolyze nonconjugated beta-glycosides into aglycones. However, when the enzyme amount and/or activity were limited, significant differences in enzyme activity toward the beta-glycosides were observed. On the other hand, beta-glycosidase was not effective in hydrolyzing the conjugated glycosides to their respective aglycones, even with increased levels of the enzyme and with prolonged incubation. The transformation of conjugated glycosides into their respective beta-glycosides will most likely result in increased hydrolysis rates and better absorption.
ABI2, a second protein phosphatase 2C involved in abscisic acid signal transduction in <i>Arabidopsis</i> (1998)

The abi2-1 (abscisic acid insensitive) mutant of Arabidopsis thaliana shows abscisic acid (ABA) insensitivity with respect to seed germination and vegetative ABA responses. We identified the ABI2 gene by a combination of positional mapping and homology to ABI1. The ABI2 protein shows 80% amino acid sequence identity to ABI1, a protein phosphatase 2C (PP2C) involved in ABA signaling. The mutation that confers the abi2-1 phenotype is equivalent to the mutation previously identified in abi1-1 and the resulting Gly168Asp abi2 protein shows a reduced PP2C activity. Thus, a pair of highly homologous PP2Cs regulate ABA signaling.
Nerve Growth Factor Gene Expression in the Developing Rat Brain (1986)

The regulation of nerve growth factor (NGF) protein and NGF messenger RNA (mRNA) in the developing rat brain has been studied to assess the hypothesis that NGF supports the differentiation of cholinergic neurons in the basal forebrain. In the adult, the major targets of these neurons, the hippocampus and neocortex, contain the highest concentrations of NGF mRNA, but comparatively low ratios of NGF protein to its mRNA. In contrast, a high concentration of NGF protein and a low concentration of NGF mRNA were seen in the basal forebrain, consistent with retrograde transport of NGF protein into this region from the neocortex and hippocampus. In these two target regions NGF and NGF mRNA were barely detectable at birth, their concentrations increased to a peak at day 21, and then NGF mRNA, but not NGF protein, declined threefold by day 35. NGF accumulation in the basal forebrain paralleled that in the target regions and preceded an increase in choline acetyltransferase, suggesting that the differentiation of cholinergic projection neurons is indeed regulated by retrogradely transported NGF. In addition, high ratios of NGF protein to NGF mRNA, comparable to that in the basal forebrain, were seen in the olfactory bulb and cerebellum, suggesting that NGF may be transported into these regions by unidentified neurons.
The effect of soft contact lens wear and time from blink on wavefront aberration measurement variation (2009)

Variability in measurements of aberrations increased significantly for odd-order aberrations when a contact lens was worn or between blinks. Fourth-order aberrations showed less effect of contact lens wear. Therefore, verification of the performance of lenses with aspheric optics on eye is feasible. Accurate assessment of higher-order aberrations is more difficult when a contact lens is worn. Both contact lens wear and time from blink increase variability in aberrations, which suggests a role for the tear film in increased aberrations with soft contact lens wear.
Direct concentration and viability measurement of yeast in corn mash using a novel imaging cytometry method (2010)

Worldwide awareness of fossil-fuel depletion and global warming has been increasing over the last 30 years. Numerous countries, including the USA and Brazil, have introduced large-scale industrial fermentation facilities for bioethanol, biobutanol, or biodiesel production. Most of these biofuel facilities perform fermentation using standard baker's yeasts that ferment sugar present in corn mash, sugar cane, or other glucose media. In research and development in the biofuel industry, selection of yeast strains (for higher ethanol tolerance) and fermentation conditions (yeast concentration, temperature, pH, nutrients, etc.) can be studied to optimize fermentation performance. Yeast viability measurement is needed to identify higher ethanol-tolerant yeast strains, which may prolong the fermentation cycle and increase biofuel output. In addition, yeast concentration may be optimized to improve fermentation performance. Therefore, it is important to develop a simple method for concentration and viability measurement of fermenting yeast. In this work, we demonstrate an imaging cytometry method for concentration and viability measurements of yeast in corn mash directly from operating fermenters. It employs an automated cell counter, a dilution buffer, and staining solution from Nexcelom Bioscience to perform enumeration. The proposed method enables specific fluorescence detection of viable and nonviable yeasts, which can generate precise results for concentration and viability of yeast in corn mash. This method can provide an essential tool for research and development in the biofuel industry and may be incorporated into manufacturing to monitor yeast concentration and viability efficiently during the fermentation process.
Site-Isolated Pt-SBA15 Materials from Tris(<i>tert</i>-butoxy)siloxy Complexes of Pt(II) and Pt(IV) (2008)

Two novel tris(tert-butoxy)siloxy complexes of Pt(II) and Pt(IV) were prepared in high yields, (cod)Pt[OSi(OtBu)3]2 (1; 87%; cod = 1,5-cyclooctadiene) and Me3Pt(tmeda)[OSi(OtBu)3] (2; 81%; tmeda = N,N,N′,N′-tetramethylethylenediamine). The structures of these compounds were determined by multinuclear NMR spectroscopy and by single-crystal X-ray analysis. The thermolytic chemistry of 1 and 2 in the solid state was studied by thermogravimetric analysis. The thermal decomposition of these complexes resulted in the formation of Pt metal, with the elimination of HOSi(OtBu)3. Precursors 1 and 2 react with the surface Si−OH groups of mesoporous SBA15 silica to generate surface-supported Pt centers. The coordination environments of the supported Pt centers in these new materials, termed Pt(II)SBA15 and Pt(IV)SBA15, were investigated using Fourier-transform infrared spectroscopy, X-ray absorption near-edge spectroscopy, and extended X-ray absorption fine structure analysis. These materials were also characterized using N2 porosimetry, powder X-ray diffraction and transmission electron microscopy. Comparisons with the molecular precursors 1 and 2 revealed many similarities, and the results are indicative of isolated Pt(II) and Pt(IV) centers. In addition, isolated Pt centers proved to be robust in inert atmosphere to 150−200 °C, which is similar to the decomposition temperatures of 1 and 2.
An investigation of the effects of the common cold on simulated driving performance and detection of collisions: a laboratory study (2012)

The finding that having a common cold is associated with reduced ability to detect collisions and respond quickly to unexpected events is of practical importance. Further research is now required to examine the efficacy of information campaigns and countermeasures such as caffeine.

Characterization of a SiC MIS Schottky diode as RBS particle detector (2018)

A 4H-SiC Schottky diode was investigated as a particle detector for Rutherford Backscattering Spectroscopy (RBS) experiment. The device was fabricated on a commercial 4H-SiC epitaxial n-type layer grown onto a 4H-SiC n+ type substrate wafer doped with nitrogen. Hafnium oxide with thickness of 1 nm was deposited by Atomic Layer Deposition and 10 nm of Ni were deposited by sputtering to form the Ni/HfO2/4H-SiC MIS Schottky structure. Current-Voltage curves with variable temperature were measured to extract the real Schottky Barrier Height (0.32 V) and ideality factor values (1.15). Reverse current and Capacitance-Voltage measurements were performed on the 4H-SiC detector and compared to a commercial Si barrier detector acquired from ORTEC. RBS data for four alpha energies (1, 1.5, 2 and 2.5 MeV) were collected from an Au/Si sample using the fabricated SiC and the commercial Si detectors simultaneously. The energy resolution for the fabricated detector was estimated to be between 75 and 80 keV.
Using the ‘Subtracto-Silhouette’ parametric view-shed method in structure planning and architectural design (2013)

Significant building silhouettes and city skylines are an important part of urban composition and contribute to a city’s identity. Pressure to accommodate higher population densities in the form of tower developments can threaten these silhouettes. This paper discusses a parametric view-shed design method for setting height restrictions or maximum building envelopes that maintain culturally significant silhouettes whilst allowing high density urban development. I describe the process of using digital special effects found in animation software reconfigured to create three-dimensional maximum planning envelopes. The technique called ‘Subtracto-Silhouette’ uses animated particle systems (normally used to simulate explosions), ‘shot’ from a specific viewing position, traced through vertices of a key building’s geometry, intersected with an extruded site boundary to create an envelope. Inside this envelope, a developer can build anything without affecting the silhouette of the building in question from the key viewing position. I demonstrate the ‘Subtracto-Silhouette’ technique by describing two case studies. Firstly I discuss input into a planning amendment for the City of Stonnington Forrest Hill Precinct in South Yarra in Victoria, where a three-dimensional planning envelope was generated to protect an historic silhouette of the adjacent Melbourne High School. The second study is an architectural proposal for the Flinders Street Station design completion where I show the technique used in both a preservation as well as generative manner. I discuss the results of the technique applied on both case studies, demonstrating its effectiveness in policy development with the resulting Amendment C58 for Forrest Hill and show how it can be used as an integrated part of schematic design process in the Flinders Street Station proposal.

A track&hold-AGC suitable for downconversion by subsampling (2003)

To date, high-speed CMOS transistors can operate in the GHz frequency range and as result high sampling frequency can be obtained. Thus, a receiver architecture using the sub-sampling principle to downconvert the signal can be now considered as a promising alternative to other kinds of architectures. In effect, sub-sampling systems are potentially more compact and more efficient, because the A/D converter is closer the antenna. In this paper, we show how it is possible to use switched-capacitor techniques to make a track-and-hold mixer and an AGC in the same circuit. This circuit is destined for the front-end of a receiver. For the basic configuration of the circuit, measurements have shown that a signal around 900 MHz could be demodulated to low frequency. An IIP3 of 19 dBm has been proved and at the same time, unfortunately, a noise figure of 20 dBm has been obtained.
Signature-based Multi-Layer Distributed Intrusion Detection System using Mobile Agents (2013)

The Internet and computer networks are exposed to an increasing number of security threats. With new types of attacks appearing continually, developing flexible and adaptive security oriented approaches is a severe challenge. Intrusions detection systems ( IDSs) are systems that try to detect attacks as they occur or after the attacks took place. IDSs collect network traffic information from some point on the network or computer system and then use this information to secure the network. In this context, signature-based network intrusion detection techniques are a valuable technology to protect target systems and networks against malicious activities. Signature-based detection is the most extensively used threat detection technique for (IDSs). One of the foremost challenges for
Spatial Distributions of GABA Receptors and Local Inhibition of Ca2+ Transients Studied with GABA Uncaging in the Dendrites of CA1 Pyramidal Neurons (2011)

GABA (γ-amino-butylic acid)-mediated inhibition in the dendrites of CA1 pyramidal neurons was characterized by two-photon uncaging of a caged-GABA compound, BCMACM-GABA, and one-photon uncaging of RuBi-GABA in rat hippocampal slice preparations. Although we found that GABA(A)-mediated currents were diffusely distributed along the dendrites, currents elicited at the branch points of the apical dendritic trunk were approximately two times larger than those elsewhere in the dendrite. We examined the inhibitory action of the GABA-induced currents on Ca(2+) transients evoked with a single back-propagating action potential (bAP) in oblique dendrites. We found that GABA uncaging selectively inhibited the Ca(2+) transients in the region adjacent (<20 µm) to the uncaging site, and that GABA uncaging was effective only within a short period after bAP (<20 ms). The strength of inhibition was linearly related to the amplitudes of the GABA currents, suggesting that the currents inhibited a sustained, subthreshold after-depolarization without preventing propagation of bAP. GABA uncaging at the dendritic branch points inhibited Ca(2+) transients farther into dendritic branches (>20 µm). Our data indicate that GABA inhibition results in spatially confined inhibition of Ca(2+) transients shortly after bAP, and suggest that this effect is particularly potent at the dendritic branch points where GABA receptors cluster.
First Detection of Human Coronavirus HKU1 in Greece, in an Immunocompromised Patient With Severe Lower Respiratory Tract Infection (2021)

<i>Human coronavirus HKU1</i> (<i>HCoV-HKU1</i>) is a RNA virus which gets in the human cells by binding to the receptor of N-acetyl-9-O-acetylneuraminic acid. <i>Human Coronaviruses (HCoVs</i>), including <i>HCoV-HKU1</i>, are globally found. <i>HCoV-HKU1</i> is responsible for upper and lower respiratory tract infections, usually with mild symptoms. In severe cases, <i>HCoV-HKU1</i> can cause life-threatening respiratory illness especially in vulnerable hosts such as elderly, children and immunocompromised patients. In Greece, <i>Respiratory Syncytial Virus (RSV)</i> and <i>influenza</i> are the most common viruses causing respiratory tract infections. Traditionally, <i>HCoVs</i> are responsible for less than 3% of respiratory infections in Greek population. HCoVs 229E and OC43 have been shown to circulate in Greece. We report the first case of lung infection in an immunocompromised woman due to <i>HCoV-HKU1,</i> that has never been before detected in Greece. <i>HCoV-HKU1</i> is related to severe disease even in healthy individuals and must be considered in the differential diagnosis of severe respiratory infections.
On the Quality of Experience of SopCast (2008)

Peer-to-Peer (P2P) file sharing has become immensely popular in the Internet. Recently, there has been a growing interest in academic and commercial environments for live streaming using P2P technology. A number of new P2P digital television (P2PTV) applications have emerged. Such P2PTV applications are developed with proprietary technologies and the quality of experience (QoE) provided by them is not well known. Therefore, investigating their mechanisms, analyzing their performance, and measuring their quality are important for researchers, operators and end users. In this paper, we present results from a measurement study of a P2PTV application called SopCast, using both objective and subjective measurement technologies. The results obtained in our study reveal important design issues of SopCast and the QoE that the end users perceive.
A review of recent work on multi-attribute access methods (1992)

Most database systems provide database designers with single attribute indexing capability via some form of B+tree. Multi-attribute search structures are rare, and are mostly found in systems specialized to some more narrow application area, e.g. geographic databases. The reason is that no multi-attirbute search structure has been demonstrated, with high confidence. Multi-attribute search is an active area of research. This paper reviews the state of this field and some of the difficult problems, and reviews some recent notable papers.
Property variation with shape in magnetic nanoelements (1999)

Nanometre scale magnetic particles (`nanoelements' or `nanomagnets') form a rich and rapidly growing new area in condensed matter physics, with many potential applications in data storage technology and magnetic field sensing. This paper reviews an extensive study into the influence of shape on the properties of nanomagnets in the size range 35-500 nm. Elliptical, triangular, square, pentagonal and circular geometries have all been considered. It is shown that the size, thickness and geometric shape of nanomagnets all play a vital role in determining the magnetic properties. The shape, size and thickness of a nanomagnet are shown to be linked to its magnetic properties by two distinct phenomena. The first is called configurational anisotropy and describes the role played by small deviations from uniformity in the magnetization field within the nanostructures, which allow unexpected higher-order anisotropy terms to appear. These anisotropies can often dominate the magnetic properties. The second is the competition which exists between exchange energy and magnetostatic energy. This competition determines whether the nanomagnets exhibit single domain or incoherent magnetization and also controls the non-uniformities in magnetization which lead to configurational anisotropy. Understanding the influence of shape opens the way to designing new nanostructured magnetic materials where the magnetic properties can be tailored to a particular application with a very high degree of precision.
Control of SIV Rebound Through Structured Treatment Interruptions During Early Infection (2000)

In a randomized controlled trial with acute simian immunodeficiency virus (SIV)-infected macaques, both highly active antiretroviral therapy (HAART) and HAART with fixed-schedule structured treatment interruption (STI-HAART; alternating 3 weeks on and 3 weeks off therapy) suppressed viral load. In the STI-HAART group, T cell virus-specific immune response (VIR) and control of viral rebound increased concurrently during subsequent interruptions. In contrast, VIR did not increase and SIV rebounded after permanent treatment withdrawal in all animals on continuous HAART. Fixed-schedule STI-HAART appears to be an effective alternative to continuous HAART for the early treatment of retroviral infection.
