Use of alveolar distraction osteogenesis for anterior maxillary defect reconstruction (2019)

Alveolar osteogenic distraction (AOD) is a biological process through which new bone formation occurs between bone segments that are gradually separated by incremental traction. This case report described the oral rehabilitation with dental implants of a patient with a vertical bone defect in the maxillary anterior region using the AOD technique. The patient presented with absence of the teeth 22, 21, 11, and 12 associated with a vertical bone defect. The AOD was performed using a supported osteodistractor device surgically installed with subsequent daily activations. After 21 days, the ideal positioning of bone fragment was confirmed and activation was ceased. Five months after the initial surgery, two dental implants were installed in the region of teeth 12 and 22. An FP3 metal-ceramic prosthesis was installed offering satisfactory esthetic results. In conclusion, the use of AOD to increase the alveolar ridge was effective and ensured rehabilitation with dental implants.
Anoxia-Induced NMDA Receptor Activation Opens Pannexin Channels via Src Family Kinases (2012)

Anoxic depolarization of pyramidal neurons results from a large inward current that is activated, in part, by excessive glutamate release during exposure to anoxia/ischemia. Pannexin-1 (Panx1) channels can be activated both by ischemia and NMDA receptors (NMDARs), but the mechanisms of Panx1 activation are unknown. We used whole-cell recordings to show that pharmacological inhibition or conditional genetic deletion of Panx1 strongly attenuates the anoxic depolarization of CA1 pyramidal neurons in acute brain slices from rats and mice. Anoxia or exogenous NMDA activated Src family kinases (SFKs), as measured by increased phosphorylation of SFKs at Y416. The SFK inhibitor PP2 prevented Src activation and Panx1 opening during anoxia. A newly developed interfering peptide that targets the SFK consensus-like sequence of Panx1 (Y308) attenuated the anoxic depolarization (AD) without affecting SFK activation. Importantly, the NMDAR antagonists, D-APV and R-CPP, attenuated AD currents carried by Panx1, and the combined application of D-APV and (10)panx (a Panx1 blocker) inhibited AD currents to the same extent as either blocker alone. We conclude that activation of NMDARs during anoxia/ischemia recruits SFKs to open Panx1, leading to sustained neuronal depolarizations.
EVALUATION OF CHEESE TEXTURE (1978)

ABSTRACT The textural characteristics of cheese were surveyed for consumer preference and sensory perception. The important textural characteristics of cheese—hardness, chewiness, springiness and adhesiveness‐were evaluated by a panel. The mechanical properties of cheese were measured with an Instron Universal Testing Machine. In making the Instron measurements, the effects of the conditions (i.e. rate of compression, rate of loading and cheese temperature) on the mechanical properties of cheese were determined. The melting property of cheese was determined by viscosity changes upon heating using a Brookfield Viscometer, Model RVT with T‐F bar. The correlations between sensory evaluation and the mechanical properties of cheese were resolved. The panel concluded that the important textural characteristics of cheese were hardness, springiness and adhesiveness. The hardness evaluated by the panel was related to the Instron determinations of the compression force, work ratio, adhesive force, force at the inflection point and viscometer determination of the melting property. The sensory assessment of springiness correlated with elastic recovery and force at the inflection point. The sensory adhesiveness rating was related to the adhesive force but inversely related to force at the inflection point.
Validation of the Name Sinoleontopodium lingianum (Asteraceae, Gnaphalieae) (2009)

Sinoleontopodium lingianum Y. L. Chen (Asteraceae, Gnaphalieae), originally described from Xizang (Tibet), China, was not validly published in 1985 because two gatherings were designated as type. The name is validated here, with the specimen bearing female florets designated as holotype.

Catastrophe Theory (1987)

The theory of general equilibrium defines equilibrium prices p as the solutions in the commodity space of the vector equation defined by equality of supply and demand, namely z(p) = 0, where z denotes aggregate excess demand. This formulation leads to a purely mathematical problem, namely the study of the properties of the solutions of the equation z(p) = 0. The first problem to come into the picture is that of existence. Its positive solution leads to new issues such as the determinateness of the solutions or their number. The fact that these problems cannot be solved uniformly with exactly the same answer for every economy necessitates the introduction of suitable parameters in terms of which the properties of the solutions of the equilibrium equation can be properly described. Let ω denote this parameter chosen in some suitable vector space Ω. This means that the aggregate demand function z can be viewed as depending on ω 0 Ω which we now denote by z(., ω) and the goal of equilibrium theory becomes one of relating the properties of the solutions to z(p, ω) = 0 with the parameter ω. In practice, one chooses for ω the initial endowments of every consumer, the equilibrium model simply describing a pure exchange economy.

ReCord: A Distributed Hash Table with Recursive Structure (2005)

We propose a simple distributed hash table called ReCord, which is a generalized version of Randomized- Chord and offers improved tradeoffs in performance and topology maintenance over existing P2P systems. ReCord is scalable and can be easily implemented as an overlay network, and offers a good tradeoff between the node degree and query latency. For instance, an n-node ReCord with O(log n) node degree has an expected latency of \theta (\log n) hops. Alternatively, it can also offer \theta (\frac{{\log n}}{{\log \log n}}) hops latency at a higher cost of o(\frac{{\log ^2 n}}{{\log \log n}}) node degree. Meanwhile, simulations of the dynamic behaviors of ReCord are studied.
The Joint British Societies’ guidelines on prevention of cardiovascular disease (2006)

The aim of the new Joint British Societies’ guidelines (JBS 2) developed by the British Cardiac Society, British Hypertension Society, Diabetes UK, HEART UK, Primary Care Cardiovascular Society and The Stroke Association is to promote a consistent multidisciplinary approach to the management of people with established atherosclerotic cardiovascular disease (CVD) and those at high risk of developing symptomatic atherosclerotic disease (British Cardiac Society et al, 2005).
A Quadrature Charge-Domain Sampler With Embedded FIR and IIR Filtering Functions (2006)

A circuit technique for integrating built-in complex finite-impulse-response (FIR) and infinite-impulse-response (IIR) filtering functions into operation of a subsampler is presented. Based on integrative multiple sampling in the charge domain, the complex FIR filtering function of the sampler provides internal anti-aliasing and image band suppression prior to quadrature downconversion by subsampling. The complex IIR filtering function, taking place at the output sampling rate of the sampler, performs further first-order channel selection filtering on the downconverted signal. An example 50-MHz IF-sampler implementation in 0.8-/spl mu/m BiCMOS demonstrating the feasibility of the technique is presented in the paper.
zenvisage: Effortless Visual Data Exploration. (2016)

Data visualization is by far the most commonly used mechanism to explore data, especially by novice data analysts and data scientists. And yet, current visual analytics tools are rather limited in their ability to guide data scientists to interesting or desired visualizations: the process of visual data exploration remains cumbersome and time-consuming. We propose zenvisage, a platform for effortlessly visualizing interesting patterns, trends, or insights from large datasets. We describe zenvisage's general purpose visual query language, ZQL (zee-quel) for specifying the desired visual trend, pattern, or insight - zenvisage draws from use-cases in a variety of domains, including biology, mechanical engineering, commerce, and server monitoring. While analysts are free to use ZQL directly, we also expose zenvisage via a visual specification interface, which we also describe in this paper. We then describe our architecture and optimizations, preliminary experiments in supporting and optimizing for ZQL queries in our initial zenvisage prototype, as well as a user study to evaluate whether data scientists are able to effectively use zenvisage for real applications.
Concept for a gas buffered annular heatpipe fuel irradiation capsule (1969)

A nuclear fuel irradiation capsule capable of handling large (approx. 300 W/cm{sup 2}) and varying fuel specimen heat fluxes while inherently maintaining nearly constant specimen temperature was conceived and two bench models successfully tested using potassium and sodium as the working fluids. Test temperatures were in the 700°C range and heat source temperatures were preserved within ±15°C while undergoing factors of three changes in power.
Broadband modelling of indoor power-line channels (2002)

The main purpose of this paper is to describe and model the characteristics of low voltage distribution lines inside consumer premises, when used as a broadband communication channel. Results from measurements performed both in the laboratory and in residential buildings, are presented and discussed. Also a channel model to simulate the behaviour of these lines for high bit-rate digital communications is proposed. The model contemplates the topology of the power grid and the characteristics of the wires and loads connected to them; it incorporates as well statistical time variation of the loads, so that the dynamic evolution of the channel performance can be evaluated.
Active graphene–silicon hybrid diode for terahertz waves (2015)

Controlling the propagation properties of the terahertz waves in graphene holds great promise in enabling novel technologies for the convergence of electronics and photonics. A diode is a fundamental electronic device that allows the passage of current in just one direction based on the polarity of the applied voltage. With simultaneous optical and electrical excitations, we experimentally demonstrate an active diode for the terahertz waves consisting of a graphene-silicon hybrid film. The diode transmits terahertz waves when biased with a positive voltage while attenuates the wave under a low negative voltage, which can be seen as an analogue of an electronic semiconductor diode. Here, we obtain a large transmission modulation of 83% in the graphene-silicon hybrid film, which exhibits tremendous potential for applications in designing broadband terahertz modulators and switchable terahertz plasmonic and metamaterial devices.
Environmental impact assessment, Guangdong, PCR (2005)

The development objective of the Livestock Waste Management in East Asia Project for East Asia and Pacific to demonstrate replicable and sustainable livestock waste management approaches that will protect and improve the local and global environment while enhancing livelihoods, particularly in public health. The Governments of China (Guangdong Province), Thailand and Vietnam have applied for the Global Environment Facility (GEF) grant for support to promote livestock waste management in respective countries to address the regional pollution problems from increased growth and intensification of livestock industry in the project countries. This environmental assessment identifies potential environmental risks and proposes measures to mitigate them. Temporary negative impacts, believed to be minor, include: vegetation damage during lagoon, or constructed wetland development for the establishment of treatment facilities; temporary land occupation at the construction sites; potential soil erosion and corresponding increase in sediment load during construction; and noise, air, and water pollution. Other impacts expected during operation include: impact on water resources (surface and groundwater due to percolation from the bottom of lagoons, breakage of lagoon embankments (above ground lagoons), overflow due to incidence of high intensity rainfall lagoon capacity; soil pollution through improper application of solid and liquid manure; explosion of biogas tanks; overproduction of solid and liquid manure and lack of available land or farmer willingness to apply the manure on agricultural land, forcing direct discharge of partially treated manure to surface water bodies; cumulative impact from large manure treatment system (eutrophication, increase in COD, coli forms, etc.); and potential health effects from pathogens and parasites through the application of solid and liquid manure. Mitigation measures include: watershed management; applying best management practices and improving enforcement in livestock manure treatment systems; and control of point and non-point source pollution of water resources.
Distinct chemokine receptor and cytokine expression profile in secondary progressive MS (2001)

The authors find qualitative differences in the systemic inflammatory response in RRMS and SPMS, indicating a distinct inflammatory environment in SPMS. Chemokine receptor expression in SPMS did not change after treatment with IFN beta-1b. It remains to be established if these findings reflect differences between RRMS and SPMS in effector or regulatory mechanisms.
Suppression of radio frequency inteference (RFI) for synchronous impulse reconstruction ultra-wideband radar (2005)

This paper is concerned with the issues associated with the suppression of radio frequency interference (RFI) for a synchronous impulse reconstruction (SIRE) ultra-wideband (UWB) synthetic aperture radar (SAR) that is currently being designed and built at the Army Research Laboratory. In this effort, we are developing the next version of the UWB radar that can employ inexpensive A/D converters to digitize wideband signals using the equivalent time sampling technique. In this presentation, we provide an analytical model for the signature of the RFI sources that are measured via an equivalent time sampling scheme. This formulation reveals spectral as well as temporal properties of the measured RFI signals that would aid a user in developing sniff (passive) data collection strategies for constructing adaptive digital signal processing methods for suppressing RFI sources.
Purification of Recombined Human Acidic Fibroblast Growth Factor (2001)

Recombined human acidic fibroblast growth factor (rhaFGF) has been isolated and purified from E.coli containing rhaFGF gene recombined plasmid by using heparinsepharose affinity chromatography and sephadex G 100 gel filtration. It showed high purity monitored by SDS PAGE, IEF and HPLC. The molecular weight of rhaFGF was determined to be roughly 16.67ku by SDS PAGE and the pI was 4.8 by IEF. N terminal amino acid sequence was also detected by Edman degradation. The high bioactivity with ED 50 of 6μg/L suggested that rhaFGF had great stimulation to cell cleavage.
Electron-Beam Induced Conformational Changes in Polypeptide Layers: an Infrared Study (1976)

Langmuir-Blodgett type polypeptide monolayers have been irradiated under conditions simulating the hazards of electron microscopic imaging. The damaging effect, i.e. the randomization of the alpha-helical layers, which occurs in the dose range between 50 and 200 e-/nm2, has been monitored by infrered dichroism.
Opposing Actions of Angiotensin II on Microvascular Growth and Arterial Blood Pressure (1996)

We performed studies to further elucidate the mechanisms of angiotensin II (Ang II)-induced angiogenesis of the microvasculature. Rats were placed on a high salt diet (4% NaCl), and Ang II was infused at a subpressor rate (5 ng/kg per minute) for 3 days. Blood pressure was measured daily for 2 control and 3 infusion days. Microvessel density in the cremaster muscle was measured at the end of the infusion. Vessel density in rats that received subpressor Ang II infusion increased by 12.6% compared with rats that received vehicle infusion. When the angiotensin type 2 (AT2) receptor antagonist PD 123319 was coinfused with Ang II, blood pressure was elevated and vessel density increased above that observed with Ang II infusion alone (23% increase). When the AT1 receptor antagonist losartan was coinfused with Ang II, blood pressure was lower than control and vessel density was reduced compared with the Ang II group but was still greater than control (7.8% increase). In this study, Ang II stimulated angiogenesis in the rat cremaster muscle; this effect was enhanced by AT2 antagonism and inhibited by AT1 antagonism. Ang II infusion at a subpressor dose resulted in a pressor response with AT2 antagonism and a depressor response with AT1 antagonism. This suggests that in the microvasculature, the AT1 receptor mediates angiogenesis and vasoconstriction, and the AT2 receptor mediates an inhibition of angiogenesis and vasodilation.
Diagnosis of Diabetes: The Size and Nature of Carbohydrate Load (1970)

The blood sugar (eighteen subjects) and serum insulin levels (sixteen subjects) following the administration of 30 gm. glucose and 45 gm. glucose per square meter of body surface area were compared. In the patients studied, the larger glucose load resulted in significantly greater blood glucose responses (area under the curve, two-hour blood glucose, three-hour blood glucose) and increased sensitivity of the test. The areas under the glucose and insulin curves with the two different glucose loads had a linear relationship, thereby providing some basis for the comparison of data obtained by the use of different amounts of glucose administered on the basis of the body surface area. The blood glucose levels following the administration of seven ounces of Glucola (75 gm. carbohydrate solution) were compared with those following the administration of (1) 100 gm. glucose in twenty-seven subjects and (2) 1.75gm. glucose/kg, of ideal body weight in twelve subjects. Although the interpretation of the individual glucose tolerance tests changed in twelve subjects, the areas under the glucose tolerance curves and summed glucose values were not significantly different whether Glucola or the two glucose loads were used thus demonstrating similarity of the Glucola and the glucose loads.
Artificial Neural Networks and Learning Techniques (2016)

The recent craze for artificial neural networks has spread its roots towards the development of neuroscience, pattern recognition, machine learning and artificial intelligence. The theoretical neuroscience is basically converging towards the basic concept that the brain acts as a complex and decentralized computer which can perform rigorous calculations in a different approach compared to the conventional digital computers. The motivation behind the study of neural networks is due to their similarity in the structure of the human central nervous system. The elementary processing component of an Artificial Neural Network (ANN) is called as ‘Neuron'. A large number of neurons interconnected with each other mimic the biological neural network and form an ANN. Learning is an inevitable process that can be used to train an ANN. We can only transfer knowledge to the neural network by the learning procedure. This chapter presents the detailed concepts of artificial neural networks in addition to some significant aspects on the present research work.
Autonomous target following by unmanned aerial vehicles (2006)

In this paper we present an algorithm for the autonomous navigation of an unmanned aerial vehicle (UAV) following a moving target. The UAV in consideration is a fixed wing aircraft that has physical constraints on airspeed and maneuverability. The target however is not considered to be constrained and can move in any general pattern. We show a single circular pattern navigation algorithm that works for targets moving at any speed with any pattern where other methods switch between different navigation strategies in different scenarios. Simulation performed takes into consideration that the aircraft also needs to visually track the target using a mounted camera. The camera is also controlled by the algorithm according to the position and orientation of the aircraft and the position of the target. Experiments show that the algorithm presented successfully tracks and follows moving targets.
Drosophila X virus RNA polymerase: tentative model for in vitro replication of the double-stranded virion RNA (1980)

An RNA polymerase activity was found to be associated with the infectious drosophila X virus particles extracted from infected flies. The rate of synthesis was at first linear as a function of time, and then a plateau was reached. During the linear phase of the synthesis, the template and product were associated as replicative intermediates which were larger than the double-stranded RNA of the drosophila X virus genome, but the final product of the reaction was indistinguishable from the RNA genome with respect to its density, sedimentation coefficient, electrophoretic mobility, and RNase resistance. The results indicated that both strands of the genomic RNA were copied. The implications of these findings with regard to other virion polymerases are discussed.
The quest for location-privacy in opportunistic mobile social networks (2013)

Location-tracking is a major privacy problem, especially with high penetration of smart-phones and GPS-enabled devices around the world. In this paper, we propose a Hybrid and Social-aware Location-Privacy in Opportunistic mobile social networks (HSLPO), a collaborative and distributed obfuscation protocol that offers location-privacy k-anonymity. HSLPO discovers the users' own social network and use it to obfuscate requests and hide the original sender's location from the Location based service (LBS) while minimizing the overhead needed to perform obfuscation. We performed extensive simulations over a map-based pseudo realistic environment to compare HSLPO to exiting protocols. Results show that HSLPO can reach higher location-privacy levels and quality of service, in term of success ratio, than other protocols while maintaining low overheads.
Ureaplasma parvum genotype, combined vaginal colonisation with Candida albicans, and spontaneous preterm birth in an Australian cohort of pregnant women (2016)

These data suggest that the presence of different species and serovars of Ureaplasma spp. in the vagina confers an increased risk of spontaneous PTB, findings which may be useful in risk assessment for identifying women who would benefit from antimicrobial treatment.
