Visual Acuity Change (1990)

This chapter discusses the symptoms, examination, and diagnostic thought processes involved in evaluating a patient experiencing an alteration in visual acuity. The following terms are frequently encountered in the setting of visual acuity loss and are therefore worthy of review.Central visual acuity: This refers to the relatively small but vital part of the visual field used for reading; it is tested with conventional eye charts and corresponds to the function of the macular area of the retina.Marcus Gunn pupil: Also called an afferent pupillary defect, a Marcus Gunn pupil is a pupil that shows a greater consensual response than direct response to light. It is detected with the swinging penlight test described in Chapter 110.Metamorphopsia: A subjective alteration in shape or form.Photopsia: The sensation of sparks or flashing lights. It is usually seen in the periphery of the visual field and most often is caused by mechanical traction on the retina.Scotoma: A focal area of visual loss in one eye.Ocular media: The normally transparent structures of the eye including the cornea, crystalline lens, and vitreous.Myopia. Nearsightedness.Hyperopia. Farsightedness.Presbyopia. The loss of ability to focus for near vision that occurs universally with increasing age. It is usually first symptomatic in the fourth and fifth decades, and usually necessitates the use of glasses for close viewing.
Research on necessity of adjusting PLE configuration (2014)

Virtualization is important in server consolidation and essential for cloud computing. Using virtualization technology, a single physical machine can provide multiple isolated virtual machine to users, which will improve the overall system resources usage. However, virtualization will also introduce new challenges and mechanisms that work functionally in traditional operating system may lead to the performance degradation of virtual machines. LHP problem arises because spin lock mechanism could not work effectively in virtualization environment. To solve LHP problem, many solutions have been proposed to reduce its performance impact on virtual machines and improve the overall system performance. A hardware assisted technology called Pause Loop Exit(PLE) has been proposed to help detecting spin lock waiter in virtual machines and then reduce the cpu time used in spinning. In this paper, we verify the necessity of adjusting PLE configuration in different scenarios. Our experiment results show that it is necessary to adjust PLE configuration when the virtual machine is running different applications and the number of virtual machines varies.
Modification of the method of generation of control finite-state machines with continuous actions based on training examples (2015)

Control finite-state machines can be used in the development of reliable control systems due to their clarity and because it is possible to formally verify them. The paper deals with resolving the problem of the generation of machines that control plants with complex behavior based on training examples. The input and output actions of the machines are given by real numbers. A method for the generation of machines is proposed. It is a modification of the previously proposed approaches based on the genetic and ant colony optimization algorithms. Changes include a new way of representing machines and improving the fitness function. The method makes it possible to generate machines whose behavior is more consistent with training examples than the behavior of machines generated by the known approaches.
Correspondence regarding Zhong et al., BMC Bioinformatics 2013 Mar 7;14:89 (2014)

Computational expression deconvolution aims to estimate the contribution of individual cell populations to expression profiles measured in samples of heterogeneous composition. Zhong et al. recently proposed Digital Sorting Algorithm (BMC Bioinformatics 2013 Mar 7;14:89) and showed that they could accurately estimate population-specific expression levels and expression differences between two populations. They compared DSA with Population-Specific Expression Analysis (PSEA), a previous deconvolution method that we developed to detect expression changes occurring within the same population between two conditions (e.g. disease versus non-disease). However, Zhong et al. compared PSEA-derived specific expression levels across different cell populations. Specific expression levels obtained with PSEA cannot be directly compared across different populations as they are on a relative scale. They are accurate as we demonstrate by deconvolving the same dataset used by Zhong et al. and, importantly, allow for comparison of population-specific expression across conditions.
DIRECT DETERMINATION OF FLEXURAL STRAINS IN PLATES USING PROJECTED GRATINGS (1977)

It is proposed in this paper to use projected gratings to determine principal strains in plates subjected to bending. The method requires the rotation of one photograph of the deformed grating over a copy of itself, the rotation taking place about the point at which the bending strains are desired. The idea previously suggested by Stetson to double differentiate holograms of bent plates has been extended and verified with an application to a plate subjected to twisting. The proposed method is easy to use and permits the determination of principal strains in plates subjected to much larger deflections than the ones that can be studied using holograms. Suggestions to improve the precision of the determination are also made. (Author)
A method for validating the compliance of business processes to business rules (2010)

Regulatory compliance of business operations and practices is increasingly becoming an area of great concern for management, costing tens of billions of dollars in compliance actions a year. This paper presents a method for validating business processes with respect to the business rules. In the proposed method, business processes are modeled with UML activity diagrams, whilst business rules are represented as OCL expressions attached to process activities and the business conceptual model. The model validation is based on the simulation of the execution of process instances based on specific scenarios. The simulation algorithm steps through the process model executing the actions associated to the activities with the help of the USE tool and checking for violations of the associated business rules. The proposed method allows the modeler to have an early feedback of possible defects that may exist in a business process model.
Research On Vehicle Anti-theft and Alarm System Using Facing Recognition (2006)

In this paper, a vehicle anti-theft system has been developed. When the car is start, this system begins to work, it captures the driver's video images using an active IR illuminator, then locates the driver's eyes and recognizes the driver's face using PCA algorithm. If the current driver is found to be unauthorized by compared his face image with the face images prestored, this system will alarm and send the unauthorized driver's image to car owner or police through CDMA or GPRS networks. This system was tested in a simulating environment with subjects of different ages, with/without glasses, and under different mumination conditions, and it was found very robust, reliable.
A New Ovitrap Made of Slow Release Natural Materials Containing Pyriproxyfen for <I>Aedes aegypti</I> (Diptera:Culicidae) Control (2013)

ABSTRACT This initial study is aimed to measure the performance of incorporating pyriproxyfen in natural materials with low environmental impact to obtain slow release formulations that can be used as larvicidal or autocidal ovitraps avoiding hatched Aedes aegypti (L.) eggs to emerge as adults. Hollow candles made of beeswax or paraffin:stearin 1:1 mixture containing pyriproxyfen 0.01 and 0.05% were prepared and used as holding water containers for larval bioassay. Pyriproxyfen was released quickly into the larvae-breeding water. Ae. aegypti larvae were introduced immediately after the addition of tap water to the hollow candles (t = 1 min) or after 1, 4, and 8 h. More than 40% of the larvae did not emerge as adults for t = 1 min, reaching 80-100% when the larvae were added after 1 or 4 h, respectively. The hollow candles were kept at room temperature, and water was replaced every 15 d. Bioassays performed every 30 d showed that the residual activity obtained for both matrices and both concentrations of pyriproxyfen was higher than 360 d, with 100% inhibition of adult emergence.
Kinetics of tautomerization of 1,3,4,7-tetramethylisoindole (1992)

The kinetics of transformation of 1,3,4,7-tetramethylisoindole(1)to 1,3,4,7-tetramethyl-1H-isoindole(2)in water or in deuterium oxide at various pH or pD at 25℃ were measuredspectrophotometricalty.The results indicated that the transformation of 1 to 2 could be promotedby acid and base.From the solvent isotope effects and the fact that the 1-position of isoindole nucleusis electron-rich,the mechanism of this transformation is suggested.
Sensor Position Determination with Flying Anchors in Three-Dimensional Wireless Sensor Networks (2008)

This paper presents a range-free position determination (localization) mechanism for sensors in a three-dimensional wireless sensor network based on the use of flying anchors. In the scheme, each anchor is equipped with a Global Positioning System (GPS) receiver and broadcasts its location information as it flies through the sensing space. Each sensor node in the sensing area then estimates its own location by applying basic geometry principles to the location information it receives from the flying anchors. The scheme eliminates the requirement for specific positioning hardware, avoids the need for any interaction between the individual sensor nodes, and is independent of network densities and topologies. The performance of the localization scheme is evaluated in a series of simulations performed using ns-2 software and is compared to that of the Centroid and Constraint range-free mechanisms. The simulation results demonstrate that the localization scheme outperforms both Centroid and Constraint in terms of a higher location accuracy, a reduced localization time, and a lower beacon overhead. In addition, the localization scheme is implemented on the Tmote Sky for validating the feasibility in the real environment.
The role of oxygen vacancies in improving the performance of CoO as a bifunctional cathode catalyst for rechargeable Li–O<sub>2</sub> batteries (2015)

The effect of oxygen vacancies on the performance of CoO as a cathode catalyst for Li–O<sub>2</sub> batteries has been investigated.
A review of experimental findings in oxy-fuel combustion at the CANMET Vertical Combustion Research Facility (2002)

An oxygen enhanced combustion technology has been developed by the Vertical Combustor Group of the CANMET Energy Technology Centre (CETC) of Natural Resources Canada. Oxy-coal combustion with flue gas recycle facilitates the capture of carbon dioxide from utility power plants for either future use or sequestration. The experimental findings of the research project were presented. The study used 2 different types of coal and different configurations for the burner. Experimental results confirmed that this new combustion technique can result in a product gas stream that is highly enriched in carbon dioxide while maintaining similar combustion characteristics as in conventional air combustion. This new technique also results in lower nitrous oxide emissions by inhibiting the thermal NOx mechanisms and recycling NOx for further reduction in the flame. 2 refs., 3 tabs., 7 figs.
Adaptive noise reduction in aircraft communication systems (2005)

In many military environments, such as fighter jet cockpits, the increasing use of digital communication systems has created a need for robust vocoders and speech recognition systems. However, the high level of ambient noise in such environments makes vocoders less intelligible and makes reliable speech recognition more difficult. One method of enhancing the noise-corrupted speech is adaptive noise cancellation. In previous research, this method was tested in a simulated cockpit environment, yielding impressive results. However, in new simulations, reflecting more realistic conditions, adaptive noise cancellation has been less successful. Spectral analysis of the data showed that the diffuseness of the ambient noise fieid, along With the microphone characteristics, has a significant effect on the performance of adaptive noise cancellation.
Development of a biodegradable alginate carrier system for antibiotics and bone cells (2006)

This study presents a novel biodegradable alginate delivery system for antibiotics and bone cells to treat infected bone defects. About 2 x 10(7) New Zealand rabbit mesenchymal stem cells (MSCs) and 5 mL vancomycin solution (50 mg/mL) were added to 5 mL of 2.5% (w/v) sodium alginate solution to form biodegradable antibiotic and MSCs alginate beads 3 mm in diameter. The alginate beads were then cultured in an osteogenic medium for 14 days. The profiles of antibiotics released from the alginate beads were evaluated using the method of high performance liquid chromatography (HPLC). The expression of osteogenic genes, including Cbfa1 and osteopontin, in the alginate beads was determined by reverse transcription-polymerase chain reaction (RT-PCR) analysis. The alkaline phosphatase activity, calcium level, and mineral deposition of the cultured cells within the alginate beads were assessed. Analytical results demonstrated that the concentrations of vancomycin eluted from the alginate beads were, for 14 days, well above the minimal inhibitory concentration of Staphylococcus aureus. Osteopontin and mRNA of Cbfa1 were detected and increased alkaline phosphatase activity and calcium levels were noted, as was a substantial mineral deposition in cultured MSCs. The PKH 26-labeled MSCs and vancomycin alginate beads were implanted in rabbit bony cavities for in vivo analysis. Implanted PKH 26-labeled MSCs were identified in the newly formed bony trabeculae in all specimens at 2 and 4 months after implantation and there was abundant mineral deposition. The results of in vitro study demonstrated sustained elution of vancomycin from the alginate carrier for 14 days and good osteogenic differentiation of cultured MSCs in the alginate carrier matrix. The results of in vivo study demonstrated the implanted MSCs participating in new bone formation. Based on experimental evidence, development of a biodegradable alginate carrier system for antibiotics and bone cells is possible, providing a potential treatment procedure for infected bone defects.
Phenotypic Heterogeneity of Monogenic Frontotemporal Dementia (2015)

Frontotemporal dementia (FTD) is a genetically and pathologically heterogeneous disorder characterized by personality changes, language impairment, and deficits of executive functions associated with frontal and temporal lobe degeneration. Different phenotypes have been defined on the basis of presenting clinical symptoms, i.e., the behavioral variant of FTD, the agrammatic variant of primary progressive aphasia, and the semantic variant of PPA. Some patients have an associated movement disorder, either parkinsonism, as in progressive supranuclear palsy and corticobasal syndrome, or motor neuron disease (FTD-MND). A family history of dementia is found in 40% of cases of FTD and about 10% have a clear autosomal-dominant inheritance. Genetic studies have identified several genes associated with monogenic FTD: microtubule-associated protein tau, progranulin, TAR DNA-binding protein 43, valosin-containing protein, charged multivesicular body protein 2B, fused in sarcoma, and the hexanucleotide repeat expansion in intron 1 of the chromosome 9 open reading frame 72. Patients often present with an extensive phenotypic variability, even among different members of the same kindred carrying an identical disease mutation. The objective of the present work is to review and evaluate available literature data in order to highlight recent advances in clinical, biological, and neuroimaging features of monogenic frontotemporal lobar degeneration and try to identify different mechanisms underlying the extreme phenotypic heterogeneity that characterizes this disease.

New development of synthesis and reactivity of seleno- and tellurophenes (2010)

Due to the many new and remarkable findings and applications that have been published in recent years in seleno- and tellurophene chemistry, this review revisits the different aspects of this chemistry, including synthesis, reactivity and applications in the field of heterocycles.
Development of an Innovative High-Temperature Gas Turbine Fuel Nozzle (1992)

The objective of the innovative high-temperature fuel nozzle program was to design, fabricate, and test propulsion engine fuel nozzles capable of performance despite extreme fuel and air inlet temperatures. Although a variety of both passive and active methods for reducing fuel wetted-surface temperatures were studied, simple thermal barriers were found to offer the best combination of operability, cycle flexibility, and performance. A separate nozzle material study examined several nonmetallics and coating schemes for evidence of passivating or catalytic tendencies. Two pilotless airblast nozzles were developed by employing finite-element modeling to optimize thermal barriers in the stem and tip. Operability of these prototypes was compared to a current state-of-the art piloted, prefliming airblast nozzle, both on the spray bench and through testing in a can-type combustor. The three nozzles were then equipped with internal thermocouples and operated at 1600°F air inlet temperature while injecting marine diesel fuel heated to 350°F. Measured and predicted internal temperatures as a function of fuel flow rate were compared. Results show that the thermal barrier systems dramatically reduced wetted-surface temperatures and the potential for coke fouling, even in an extreme environment.
Trophic action of local intraileal infusion of insulin-like growth factor I: polyamine dependence (1992)

Experiments were performed to determine potential growth-promoting effects of human recombinant insulin-like growth factor I (hrIGF-I) in the gastrointestinal tract. IGF-I and IGF-II, but not insulin, were potent (half-maximal effective concentration 0.3 nM) and efficacious inducers of the growth-related enzyme ornithine decarboxylase (ODC) in the gut-derived cell line IEC-6. Maximal ODC induction was observed after treatment of cells with 10 nM IGF-I. In whole animal experiments, bolus intraileal injection of 10 nM hrIGF-I in anesthetized rats induced a 300% increase in ileal mucosal ODC activity, which was sensitive to inhibition with difluoromethylornithine (DFMO). Rats were implanted intraperitoneally with osmotic minipumps filled with 0.9% NaCl or 10 nM IGF-I that was delivered to the ileal lumen by a short Silastic catheter. Sixty-six hours of 1 microliter/h intraluminal IGF-I infusion produced an approximate doubling of mucosal wet weight (NaCl 50 mg vs. IGF-I 102 micrograms/2 cm mucosa) and total mucosal RNA, DNA, and protein content over that in rats that were infused with NaCl. Intraperitoneal treatment with 200 mg/kg DFMO three times per day had little effect on ileal mucosal mass, but completely inhibited the trophic response to IGF-I infusion. IGF-I infusion had no effect on body weight.
Dislipemias en Pacientes VIH (2015)

Abstract Since the introduction of highly active antiretroviral therapy (ART) in the treatment of HIV/AIDS patients, we have observed a change in the development of the disease, becoming a chronic therapeutically containable condition. The increase in survival goes together with associated diseases; cardiovascular ones have become relevant, being earlier and more severe. Dyslipidemias have a leading role in this pathology. In this work, we analyze their incidence and characteristics in HIV patients, with and without ART treatment. Lipid profile was different in the pre-treatment stage (low HDL, low total Cholesterol and normal TG) from the stage under ART (marked increase of TG and to a lesser extent of total Cholesterol and LDL), with a significant association of the use of Protease Inhibitors (PIs) and CD4 levels lower than 200/mm3.
THE LIVES AND TIMES OF RESIDENT TRADERS IN TUVALU: AN EXERCISE IN HISTORY FROM BELOW (1987)

Seaborne trade in the Pacific last century depended on shipping, capital, connections, and markets. So crucial were these impersonal forces that they encourage an economic determinism by diverting attention from the human dimension of the business. In particular it is easy to overlook those who assumed the roles, so to speak, of hewers of wood and drawers of water. Seaborne trade, in short, was more than a matter of “prices, percentages, competitors and navigation” (Firth 1978: 130); it was equally a matter of deckhands afloat, copra cutters ashore, and resident traders scattered throughout the archipelagoes. To put it another way, the interarchipelago trade in copra, beche-de-mer, and pearlshell could never have been an economic proposition unless the trading vessels involved had been manned by “native” crews who were cheap to maintain and feed; or had not thousands of Islanders throughout the Pacific cut the copra that those vessels carried away to distant markets. Nor could the copra trade have been conducted in the absence of the underrated yet ubiquitous European resident trader, sometimes trading on his own account but more commonly in company employment, for whom the Pacific became “home.” This breed of men has been pushed to the farthest margins of Pacific historiography. They seldom penned their memoirs and have never received preferential treatment from historians. Furthermore, their marginal status within the European trading system has obscured, then
Precise and Continuous Time and Frequency Synchronisation at the 5×10-19 Accuracy Level (2012)

The synchronisation of time and frequency between remote locations is crucial for many important applications. Conventional time and frequency dissemination often makes use of satellite links. Recently, the communication fibre network has become an attractive option for long-distance time and frequency dissemination. Here, we demonstrate accurate frequency transfer and time synchronisation via an 80 km fibre link between Tsinghua University (THU) and the National Institute of Metrology of China (NIM). Using a 9.1 GHz microwave modulation and a timing signal carried by two continuous-wave lasers and transferred across the same 80 km urban fibre link, frequency transfer stability at the level of 5×10⁻¹⁹/day was achieved. Time synchronisation at the 50 ps precision level was also demonstrated. The system is reliable and has operated continuously for several months. We further discuss the feasibility of using such frequency and time transfer over 1000 km and its applications to long-baseline radio astronomy.
