Threat Analysis for Wearable Health Devices and Environment Monitoring Internet of Things Integration System (2019)

With the rapid development of Internet of Things (IoT) applications, heterogeneous device management issues tend to arise in architecture security due to hardware computing power, types of software, data transmission interfaces, and networking protocols. Even during data exchange between devices and systems, traditional IoT devices are prone to the disclosure of personal information, which compromises privacy. Thus, planning an effective information security management strategy has become an essential part of application development. This paper presents a strategy to achieve information security verification and risk assessment for an IoT-based personal health information system. Using several interfaces of IoT devices, including Wi-Fi and Bluetooth, we simulate possible attack hypotheses and define test methods and evaluation methods suitable for each device. In our application systems for information security analysis, we also consider and integrate weaknesses of the system architecture to achieve a more complete information security threat analysis.
Positive Temperature Coefficient of Electrical Resistivity below 150 K in Barium Strontium Titanate (2004)

The resistivity of Ba (1– y )(1– x ) Sr y (1– x )La x TiO 3 ceramics with x = 0.0025 and y = 0.25, 0.5, 0.75, and 0.9 was measured between 50 and 400 K. A resistivity anomaly corresponding to the positive temperature coefficient of electrical resistivity (PTCR) effect was observed for all compositions. The onset temperature decreased from 320 K ( y = 0.25) to 70 K ( y = 0.9). The extent of the PTCR effect was significantly enhanced for the strontium‐rich composition and reached ∼8 orders of magnitude for y = 0.9. These results strongly suggested the possibility to fabricate PTCR devices based on (Sr,Ba)TiO 3 ceramics for application at cryogenic temperatures.
Association of Interleukin-1β (<i>IL1B</i>) Polymorphisms with Graves' Ophthalmopathy in Taiwan Chinese Patients (2010)

The data for IL1B polymorphisms and the association of GD and GO with plasma IL1β levels show that IL1B polymorphisms may be associated with the development of GD and GO.
Oil palm (Elaeis guineensisJacq.) tissue culture ESTs: Identifying genes associated with callogenesis and embryogenesis (2008)

This study has provided an overview of genes expressed during oil palm tissue culture. Candidate genes with expression that are modulated during tissue culture were identified. However, in order to confirm whether these genes are suitable as early markers for embryogenesis, the genes need to be tested on earlier stages of tissue culture and a wider range of genotypes. This collection of ESTs is an important resource for genetic and genome analyses of the oil palm, particularly during tissue culture development.
Amplification and lasing at 1350 nm in a neodymium doped fluorozirconate fibre (1988)

The gain spectrum of a 0.5 m length of neodymium doped fluorozirconate multimode fibre has been measured in the 1350 nm wavelength region. The peak of the gain spectrum occurs at 1354 nm whilst the peak of fluorescence is at 1320 nm, suggesting the presence of excited state absorption of lasing photons at shorter wavelengths. Lasing characteristics at 1050 nm and 1354 nm are also reported.
Genome-wide comparative phylogenetic analysis of the rice and Arabidopsis Dof gene families (2003)

According to our analysis, the Dof gene family in angiosperms is organized in four major clusters of orthologous genes or subfamilies. The proposed clusters of orthology and their further analysis suggest the existence of monocot specific genes and invite to explore their functionality in relation to the distinct physiological characteristics of these evolutionary groups.
PeerReview (2007)

We describe PeerReview, a system that provides accountability in distributed systems. PeerReview ensures that Byzantine faults whose effects are observed by a correct node are eventually detected and irrefutably linked to a faulty node. At the same time, PeerReview ensures that a correct node can always defend itself against false accusations. These guarantees are particularly important for systems that span multiple administrative domains, which may not trust each other.PeerReview works by maintaining a secure record of the messages sent and received by each node. The record isused to automatically detect when a node's behavior deviates from that of a given reference implementation, thus exposing faulty nodes. PeerReview is widely applicable: it only requires that a correct node's actions are deterministic, that nodes can sign messages, and that each node is periodically checked by a correct node. We demonstrate that PeerReview is practical by applying it to three different types of distributed systems: a network filesystem, a peer-to-peer system, and an overlay multicast system.
Osmostress response in <i>Bacillus subtilis</i>: characterization of a proline uptake system (OpuE) regulated by high osmolarity and the alternative transcription factor sigma B (1997)

Exogenously provided proline has been shown to serve as an osmoprotectant in Bacillus subtilis. Uptake of proline is under osmotic control and functions independently of the known transport systems for the osmoprotectant glycine betaine. We cloned the structural gene (opuE) for this proline transport system and constructed a chromosomal opuE mutant by marker replacement. The resulting B. subtilis strain was entirely deficient in osmoregulated proline transport activity and was no longer protected by exogenously provided proline, attesting to the central importance of OpuE for proline uptake in high-osmolarity environments. The transport characteristics and growth properties of the opuE mutant revealed the presence of a second proline transport activity in B. subtilis. DNA sequence analysis of the opuE region showed that the OpuE transporter (492 residues) consists of a single integral membrane protein. Database searches indicated that OpuE is a member of the sodium/solute symporter family, comprising proteins from both prokaryotes and eukaryotes that obligatorily couple substrate uptake to Na+ symport. The highest similarity was detected to the PutP proline permeases, which are used in Escherichia coli, Salmonella typhimurium and Staphylococcus aureus for the acquisition of proline as a carbon and nitrogen source, but not for osmoprotective purposes. An elevation of the osmolarity of the growth medium by either ionic or non-ionic osmolytes resulted in a strong increase in the OpuE-mediated proline uptake. This osmoregulated proline transport activity was entirely dependent on de novo protein synthesis, suggesting a transcriptional control mechanism. Primer extension analysis revealed the presence of two osmoregulated and tightly spaced opuE promoters. The activity of one of these promoters was dependent on sigma A and the second promoter was controlled by the general stress transcription factor sigma B.
Real time noninvasive assessment of external trunk geometry during surgical correction of adolescent idiopathic scoliosis (2009)

Tracking of the external geometry of the trunk during surgical correction is useful to monitor changes occurring under the sterile draping sheets. Moreover, this technique can used be used to reach the optimal configuration on the operating frame before proceeding to surgery. The current tracking technique was able to detect significant changes in trunk geometry caused by posterior instrumentation of the spine despite significant correction of the spinal curvature. It could therefore become relevant for computer-assisted guidance of surgical maneuvers when performing posterior instrumentation of the scoliotic spine, provide important insights during positioning of patients.

Precipitation and Phase Transformation of Copper Particles in Low Alloy Ferritic and Martensitic Steels (1999)

In order to make clear the influence of matrix microstructures on age-hardening behavior in copper containing steels, the precipitation and the phase transformation of copper particles during isothermal aging were investigated by differential scanning calorimetry (DSC), transmission electron microscopy (TEM) and atom-probe field ion microscopy (AP-FIM). In ferrite, it was found from the DSC analysis and the TEM observations that copper clusters, bcc and 9R structures exist prior to the formation of the stable fcc copper phase, and that the main structure of the particles in a maximum hardness specimen is a bcc structure. The bcc→9R transformation was found to occur during the particle coarsening by the qualitative analysis of the DSC curves and the kinetics was discussed by the free energy calculation in Fe-matrix/Cu-precipitate system. In martensite, most of the copper precipitated on laths and on dislocations during isothermal aging. This resulted in the decrease of the amount of bcc particles and the considerable decrease of maximum age-hardness of the specimen. On the other hand, the age-hardening behavior of 80%-deformed ferrite was almost the same as that of ferrite, although the dislocation density of the deformed ferrite was larger than that of ferrite. In this paper, the factors controlling the precipitation and the phase transformation of copper particles in association with the hardening behavior are discussed with focus on the effect of defects (dislocation, vacancy) in steels. Moreover, the effect of manganese addition on the precipitation of copper particles is discussed.
Translating and Disseminating Research- and Practice-Based Criteria to Support Evidence-Based Intervention Planning (2008)

These evidence criteria provide the foundation for the translation and dissemination of evidence-based intervention planning processes through a Web-based technical advisement system for public healthcare practitioners. Limitations and future directions are considered.
Designing programming languages for analyzability: a fresh look at pointer data structures (2003)

A programming language mechanism and associated compiler techniques which significantly enhance the analyzability of pointer-based data structures frequently used in nonscientific programs are proposed. The approach is based on exploiting two important properties of pointer data structures: structural inductivity and speculative traversability. Structural inductivity facilitates the application of a static interference analysis method for such pointer data structures based on path matrices, and speculative traversability is utilized by a novel loop unrolling technique for while loops that exploit fine-grain parallelism by speculatively traversing such data structures. The effectiveness of this approach is demonstrated by applying it to a collection of loops found in typical nonscientific C programs.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Rethinking Self-driving: Multi-task Knowledge for Better Generalization and Accident Explanation Ability (2018)

Current end-to-end deep learning driving models have two problems: (1) Poor generalization ability of unobserved driving environment when diversity of training driving dataset is limited (2) Lack of accident explanation ability when driving models don't work as expected. To tackle these two problems, rooted on the believe that knowledge of associated easy task is benificial for addressing difficult task, we proposed a new driving model which is composed of perception module for \textit{see and think} and driving module for \textit{behave}, and trained it with multi-task perception-related basic knowledge and driving knowledge stepwisely. Specifically segmentation map and depth map (pixel level understanding of images) were considered as \textit{what \& where} and \textit{how far} knowledge for tackling easier driving-related perception problems before generating final control commands for difficult driving task. The results of experiments demonstrated the effectiveness of multi-task perception knowledge for better generalization and accident explanation ability. With our method the average sucess rate of finishing most difficult navigation tasks in untrained city of CoRL test surpassed current benchmark method for 15 percent in trained weather and 20 percent in untrained weathers.

Design and experiments of plasma jet igniter for aeroengine (2013)

A plasma jet ignition technology was studied for aeroengine combustor. The advantages of compact structure and advanced performance of air-cooled plasma jet igniter had been tested and verified in the opening test. The plasma jet igniter could produce a continuous plasma jet, stable and reliable ignition. The influence factors of plasma jet ignition aerodynamic and structure were studied in the opening test. Continuous plasma jet was closely related to inlet pressure and flow, simultaneously to the igniter nozzle geometry and throat size. Based on the stable continuous plasma jet, some methods were explored in order to reduce plasma output power, optimize the structure design, and improve the thermal protective. The plasma jet igniter applied to aeroengine combustor was identified initially. For combustion chamber with the igniter, altitude ignition performance were experimented for the inlet pressure of plasma ignition from 10 kPa to 50 kPa, the flow of plasma jet not more than 0.20 g/s, and energy output of ignition from 800 W to 1500 W. The test results were compared with that of conventional aeroengine high energy ignition system. The results show that the plasma jet igniter is better than the conventional one.
Comparison of Antibacterial Activities of Selected Species of Zingiberaceae Family and Some Synthetic Compounds (2005)

This study describes the antibacterial activity of ginger (G), mangoginger (M) and turmeric (T) and mixtures thereof i.e. ginger and mangoginger (GM), ginger and turmeric (GT), turmeric and mangoginger (TM), and a mixture of peels (P) and 4 synthetic compounds (HC-1, HC-2, HC-3 and HC-4). Extracts of these compounds were studied on Escherichia coli, Bacillus subtilis and Staphylococcus aureus. Both aqueous (heated and unheated extracts) and organic solvents, 1, 4-Dioxan, N,N,dimethylformamide (DMF), were used for antibacterial assay. Growth inhibition was evaluated by the disc diffusion and agar ditch methods. The antibacterial activity of heated extracts was greater than that of the unheated extracts of all the 3 spices alone or mixtures thereof against all the 3 bacterial strains. When the organic acid extracts were studied, the antibacterial activity of 1, 4-Dioxan extracts of T, GT and TM showed the highest activity against E. coli. The 1, 4-Dioxan and DMF extracts of M showed the highest activity against B. subtilis. The antibacterial activity of G in 1, 4-Dioxan showed the highest activity against S. aureus. Extracts in DMF did not show any activity. The synthetic compounds in 1, 4-Dioxan showed better antimicrobial activity than did DMF extracts. In conclusion, amongst the studied members of Zingiberaceae mangoginger and mixtures containing mangoginger showed maximum antibacterial activity and the synthetic compound HC-3 showed antibacterial activity equivalent to that of mangoginger. Both natural and synthetic compounds extracted in 1, 4-Dioxan gave better results. Therefore, these 2 compounds can be used as lead molecules in drug designing.

Prehistory in Action (1992)

Molecular geneticists propose that all living human beings are descendants of a single woman who lived about 350,000 years ago. Evolutionary linguists propose that the cladogram of all human languages follows closely the cladogram of the molecular geneticists. Does it then folow that all of modern English derives from the language spoken by our prehistoric mother? And, if so, how is it that synonyms arise?
Effects of gold nanoparticles deposition on the photocatalytic activity of titanium dioxide under visible light (2009)

The effects of gold nanoparticles deposited on titanium dioxide on the photocatalytic oxidative degradation of two organic substrates, i.e.formic acid and the azo dye Acid Red 1, and on the parallel O2reduction yielding hydrogen peroxide have been investigated under visible light irradiation. The method employed to reduce Au(III) to metallic gold in the preparation of Au/TiO2 photocatalysts was found to affect their photoactivity, also by modifying the properties of TiO2. The presence of gold on TiO2 facilitates both the electron transfer to O2 and the mineralization of formic acid, which mainly proceeds through direct interaction with photoproduced valence band holes. The so-formed highly reductant CO2˙− intermediate species may contribute in maintaining gold in metallic form. The controversial results obtained in the photocatalytic degradation of the dye were rationalised by taking into account that with this substrate, which mainly undergoes oxidation through a hydroxyl radical mediated mechanism, the photogenerated holes may partly oxidise gold nanoparticles, which consequently act as recombination centres of photoproduced charge carriers.
EVIDENCE: an FPGA-based system for photon event identification and centroiding (2002)

A high performance processing system for event identification and centroiding to be used in a photon counting detector for space applications is presented. In order to satisfy the processing requirements dictated by the identification problem, an ad-hoc system based on field programmable gate arrays (FPGAs) has been designed. FPGAs are shown able to achieve the best performance required by the envisioned application, as compared to former systems based on alternative off-the-shelf technologies. FPGAs also allow matching low design and development costs with the requirements of fast identification and flexibility in making the system adequate for ever increasing counting rates, and in implementing more sophisticated centroiding algorithms.
The secure networked truck - protecting america's transportation infrastructure (2005)

Following the September 11, 2001 terrorist attacks on the US, the Department of Transportation (DOT) was asked to identify areas within the transportation system that were vulnerable to terrorist attack (National Petroleum News, vol. 93, no. 12, p. 10, 2001). Amid suspicions that hazardous chemicals and nuclear waste could be employed in a homeland terrorist attack the FBI and Department of Transportation has issued warnings to the trucking industry to be alert for suspicious activity. One major area of concern identified was the transportation of hazardous materials (hazmat). The threat exists that a truck could be stolen or hijacked and it or its load used as a weapon. For example a gasoline tanker could be used in a suicide attack. A load of explosives, for example, could be used to deliver or create a weapon of mass destruction (WMD). To mitigate this threat, the concept of the secure networked truck has been developed that will provide additional security in the form of a vehicle immobilizer, door locks, smart values and other security devices that can either operate autonomously based on certain local conditions, such as a door being opened, or be activated over-the-air by a dispatcher or other asset controller. Here the author examines satellite and terrestrial location based command and control security systems as they relate to the trucking industry, and how they may prevent a terrorist using a truck to carry out an attack. These systems will of course serve a dual purpose and also act as a deterrent to cargo theft. The crime of cargo theft is discussed as there is speculation that the proceeds from cargo theft may be used to fund terrorist activity. Finally, the author raises the question of whether the secure networked truck is but a necessary part of the continually evolving supply chain, a supply chain that today must provide integrity, confidentiality and assurance - all tenets of good security.
Histamine mediates osteoclastic resorption only during the acute phase of bone loss in ovariectomized rats (2006)

Short-term studies have shown that histamine is involved, via its H2 receptors (H2R), in the mediator network regulating trabecular bone loss in long bones of ovariectomized (OVX) rats. It is not known whether this effect of histamine persists over time or involves other skeletal sites. In this study, rats were maintained for 6 months postOVX and treated daily with saline or famotidine (10 mg kg(-1)), an H2R antagonist. At the end of the experimental period, femur trabecular bone mass was markedly decreased in OVX rats, whether or not they were treated with famotidine. In contrast, in the fourth lumbar vertebra, where bone loss starts later than in the femur, famotidine treatment attenuated the decline in trabecular bone volume, protected the trabecular architecture, maintained the thickness of the cortices and reduced the numbers of osteoclasts and tartrate-resistant acid phosphatase-positive preosteoclasts, whereas it had no influence on bone formation parameters. In vertebral bone marrow of OVX rats, the numbers of mast cells (MCs) and non-MC histamine-producing cells increased, while famotidine treatment significantly diminished both cell populations. These data show that H2R antagonism does not protect trabecular bone mass in the long term, and that short-term protection involves all bones. Histamine is involved during the early phase of strong osteoclastic resorption but not during the late phase of slower resorption, suggesting that different mediator networks control the two phases of destruction. Histamine would be part of the network mediating the early phase.
Technology of Data Mining (2014)

In recent years, due to the rapid development and wide application of science and technology, so as to further accelerate the pace of development of the informationization construction. Although the collection ability and information quantity information has been further improved and growth, but the people of large-scale data analysis, knowledge utilization is not enough; the simple query and statistical system with traditional data will be very difficult to meet the development demand of modern society. Since the introduction of mass data of current social development technology can better meet the needs of mining, the data warehouse shift data information into a reusable, high application value, which provides reliable technical support for the development of the industry.
