Application of an aqueous nanometric aluminum oxide suspension for fluoride remediation (2011)

A nanometric aluminum oxide suspension synthesized from AlCl3 (solution) has been discussed for its potential application as a low cost fluoride remediation system.
The phase synthesized was identified as AlO (JCPDS card no: 75-0278) and e-Al2O3(JCPDS card no: 35-0121). The isoelectric point of the suspension was at pH 7.61.
Optimum remediation pH was determined to lie in between 6.5 to 7.0. The maximum loading capacity was predicted to be 110 mg/g from Langmuir isotherm and 127 mg/g from Freundlich isotherm. Presence of interfering ions in a simulated real water matrix does not appreciably alter the remediation capacity. Eight real water samples were found to be effectively remediated with triplicate % r.s.d falling in between 0.1 to 1.3.
Effect of modified Widman flap surgery and systemic tetracycline on the subgingival microbiota of periodontal lesions (1988)

33 subjects with evidence of active destructive periodontal disease were treated by modified Widman flap surgery and systemic tetracycline (1 g/day for 21 days). Subgingival plaque samples were taken from 41 sites in 12 of these subjects before and 6 months after therapy for predominant cultivable microbiota studies. Mean pocket depth and attachment levels in the 41 sampled sites were 7.1 +/- 2.9 mm and 7.7 +/- 3.2 mm prior to therapy and 4.8 +/- 2.3 mm and 6.2 +/- 3.4 mm after therapy. B. melaninogenicus and V. parvula were more frequently detected in samples taken after therapy, while S. intermedius, S. morbillorum, S. uberis and W. recta were less frequently detected after therapy. A. actinomycetemcomitans were detected in 7 sites pretherapy and 1 site post therapy. The frequency of detection of B. gingivalis and B. intermedius was virtually unchanged. The mean levels of the Actinomyces sp., A. actinomycetemcomitans, B. gingivalis, B. intermedius, S. morbillorum, S. uberis and W. recta were decreased after therapy, while the mean levels of B. melaninogenicus, S. mitis, S. sanguis II and V. parvula were increased after therapy. V. parvula showed the greatest increase to 8.2% of the microbiota. In the second phase of the study, subgingival plaque samples from 94 sites in the 33 treated subjects were analyzed by predominant cultivable techniques. As a result of therapy, 24 sites exhibited attachment loss greater than 2 mm, 23 sites exhibited "gain" greater than 2 mm and the remaining 47 sites were considered to be unchanging.(ABSTRACT TRUNCATED AT 250 WORDS)
A generic 2.0 &#x00D7; 2.5 mm<sup>2</sup> UMTS FBAR duplexer based on 8-pole near-elliptic filters (2009)

UMTS antenna duplexers for handsets require high levels of wide-band rejection while still achieving high isolation, low insertion loss, and good return loss in-band. Several of the UMTS duplexers also require very steep filter skirts due to a very small guardband between transmit (Tx) and receive (Rx) frequency bands (Bands 2 and 8 have ∼1% guardband). Without sizeable inductors to stretch the bandwidth, this demands a higher effective coupling coefficient and a near-ideal placement of a large number of poles and zeroes to achieve steep filter skirts while maintaining acceptable insertion loss with so many resonators. Signifcantly higher quality factor (Q) than previously available is essential to maintain good insertion loss in these designs. Cross-coupling elements shift the frequency of existing ladder filter zeroes to place them near ideal alignment to meet in-band rejection requirements without the need for tight tolerance on components.
Long-acting steroidal contraceptive systems. (1980)

This is a general discussion of the development of long-acting steroidal contraceptive systems. This is believed to be an important solution to the problems of effectiveness, safety, and acceptability of steroidal contraceptives, especially in developing countries. Since side effects from hormones are known to be dose-dependent, the aim is to develop a contraceptive with a great enough amount of hormone to prevent pregnancy but not so great as to cause side effects. There are 2 different approaches to the delivery of fertility control: the pharmacologic and the systems engineering approaches. The pharmacologic approach is typified by an injectable steroid while the systems engineering approach involves inert drug carriers which control the release of the hormone. Delivery of long-acting substances can either be made locally or systemically. The state of the art regarding long-acting contraception is reviewed with a thorough discussion of the process of development, dosage requirements, and method of delivery of the following types of contraceptives: 1) injectable depot formulations; 2) subdermal implants; 3) medical intrauterine systems; 4) medicated intravaginal systems; 5) medicated intracervical systems; and 6) biodegradable systems.
Pruning via number of links and neuron activities (2002)

A new pruning concept that is based on the number of connections or links and the neuron activities and/or sensitivities is proposed. The concept can be applied to a number of existing algorithms which would then generate a consistent subnetwork even when starting with different initial topologies. The concept can easily be implemented using existing neural network chips by fixing the number of input and output links of each neuron. This new concept is presented and its adaptation on some existing algorithms is outlined. Some of the experimental results are included.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Amplification and expression of c-Ki-ras oncogene in human ovarian cancer. (1990)

The amplification and expression of the cellular oncogene c-Ki-ras have been detected in twelve tissue specimens of human ovarian adenocarcinoma, one ascites of ovarian cancer and ovarian cancer cell line NIH: OVCAR-3. Four out of the twelve cancer tissue specimens, one specimen of cancer ascites cells and the NIH: OVCAR-3 cancer cell line showed elevated amplification of c-Ki-ras, as compared to the human fibroblast cell line FS4 and normal ovarian tissues. The amplification of the c-Ki-ras gene showed some correlation with clinical stages of ovarian cancer. The levels of c-Ki-ras specific RNA transcripts and ras gene product p21 were also elevated in these four cancer tissue specimens. Surprisingly, a discrepancy between amplification and expression of c-Ki-ras was noted in five of the other eight cancer tissue specimens, in which enhanced expression of c-Ki-ras was present without the accompanying elevated amplification of c-Ki-ras. The results do provide some clues to understanding the possible mechanisms of tumorigenesis in human ovarian cancer.
Demonstration of an excited-state Faraday anomalous dispersion optical filter at 1529 nm by use of an electrodeless discharge rubidium vapor lamp (2012)

An excited-state Faraday anomalous dispersion optical filter (ESFADOF) operating on the rubidium 5P3/2-4D5/2 transition (1529.4 nm in vacuum) is demonstrated, which utilizes an electrodeless discharge lamp rather than a laser-pumped Rb vapor cell as in a traditional ESFADOF system. When the lamp operates in the red mode with 3.5 W radio-frequency driving power, a twin-peak line-shaped transmission spectrum is obtained, which has a maximum transmittance of 21.9% (without taking into account the system loss and fluorescence background). ESFADOF by exploiting the 5P3/2-4D3/2 transition (1529.3 nm in vacuum) is also explored. A single-peak transmission spectrum with a maximum transmittance of about 3% is achieved. The electrodeless discharge lamp based ESFADOF holds promise for realizing a compact, low-cost, and good long-term frequency-stabilized laser system for optical communication applications.
Optimal 3D selection technique assignment using real-time contextual analysis (2013)

Selection in 3D virtual environments can vary wildly depending on the context of the selection. Various scene attributes such as object velocity and scene density will likely impact the user's ability to accurately select an object. While there are many existing 3D selection techniques that have been well studied, they all tend to be tailored to work best in a particular set of conditions, and may not perform well when these conditions are not met. As a result, designers must compromise by taking a holistic approach to choosing a primary technique; one which works well overall, but is possibly lacking in at least one scenario. We present a software framework that allows a flexible method of leveraging several selection techniques, each performing well under certain conditions. From these, the best one is utilized at any given moment to provide the user with an optimal selection experience across more scenarios and conditions. We performed a user study comparing our framework to two common 3D selection techniques, Bendcast and Expand. We evaluated the techniques across three levels of scene density and three levels of object velocity, collecting accuracy and timing data across a large sample of participants. From our results, we were able to conclude that our auto-selection technique approach is promising but there are several characteristics of the auto-selection process that can introduce drawbacks which need to be addressed and minimized.

Synaptic Depression and the Temporal Response Characteristics of V1 Cells (1998)

We explore the effects of short-term synaptic depression on the temporal dynamics of V1 responses to visual images by constructing a model simple cell. Synaptic depression is modeled on the basis of previous detailed fits to experimental data. A component of synaptic depression operating in the range of hundreds of milliseconds can account for a number of the unique temporal characteristics of cortical neurons, including the bandpass nature of frequency-response curves, increases in response amplitude and in cutoff frequency for transient stimuli, nonlinear temporal summation, and contrast-dependent shifts in response phase. Synaptic depression also provides a mechanism for generating the temporal phase shifts needed to produce direction selectivity, and a model constructed along these lines matches both extracellular and intracellular data. A slower component of depression can reproduce the effects of contrast adaptation.
Intracolonic by-pass: a new technique to prevent anastomotic complications in colon and rectal surgery. (1984)

A new technique, the "intracolonic bypass" designed to prevent anastomotic complications after colonic and rectal resections is reported. It consists of a latex tube fixed to the intestinal wall above the anastomosis, which prevents the fecal stream from reaching the anastomotic site. The tube is retained until complete healing of the anastomosis and then excreted spontaneously through the anus. This new and simple technique avoids the disadvantages of a temporary diverting ileostomy or colostomy.
Toll-Like Receptors and Relevant Emerging Therapeutics with Reference to Delivery Methods (2019)

The built-in innate immunity in the human body combats various diseases and their causative agents. One of the components of this system is Toll-like receptors (TLRs), which recognize structurally conserved molecules derived from microbes and/or endogenous molecules. Nonetheless, under certain conditions, these TLRs become hypofunctional or hyperfunctional, thus leading to a disease-like condition because their normal activity is compromised. In this regard, various small-molecule drugs and recombinant therapeutic proteins have been developed to treat the relevant diseases, such as rheumatoid arthritis, psoriatic arthritis, Crohn's disease, systemic lupus erythematosus, and allergy. Some drugs for these diseases have been clinically approved; however, their efficacy can be enhanced by conventional or targeted drug delivery systems. Certain delivery vehicles such as liposomes, hydrogels, nanoparticles, dendrimers, or cyclodextrins can be employed to enhance the targeted drug delivery. This review summarizes the TLR signaling pathway, associated diseases and their treatments, and the ways to efficiently deliver the drugs to a target site.
Modeling of Through-the-Snow Electric Field Propagation for Rescue Systems (2011)

Propagation models for avalanche rescue systems are studied here. The paper focuses on the through-the-snow electric field propagation at ISM frequencies for air, snow and three-layered models. The latter includes geometrical optics and Sommerfeld-type integrals using numerical solution in Matlab. Furthermore, FEM analysis by COMSOL serves to validate numerical integration. In addition, the simulation results are fitted to experimental data, finding the optimal model for the problem under study. The FEM method allows considering more realistic geometries for the problem, albeit the other solving methods are simpler and require fewer computational resources.
A Software Architecture for Zero-Copy RPC in Java (1998)

RPC has established itself as one of the more powerful communication paradigms for distributed computing. In recent years, object-oriented languages have impacted RPC semantics, with a number of variants providing remote method invocation and various forms of distributed object systems. At the same time, performance has changed little with the bottleneck being the network transport, in particular the in-kernel protocol implementations. This paper describes J-RPC, an RPC architecture that leverages user-level network interfaces (UNI) to circumvent the kernel on the critical path. It describes how the wire format and the RPC system can be engineered to allow zero-copy reception of Java objects and zero-copy transmission of arrays. All objects received are fully type-checked and can be directly used by the receiving program. The design is connection-oriented for performance and leverages the JVM’s garbage collector when managing receive buffers. An implementation built from an off-the-shelf JVM and a commercial UNI is used to evaluate the architecture and the tradeoffs of type-safe, zero-copy data marshaling. 1
Dynamic composition of process federations for context aware perception of human activity (2004)

We describe a distributed software model for context-aware perception of human activity. The basic building blocks in this model are perceptual modules, composed of a data transformation component and a control component. Modules are assembled into perceptual processes controlled by a reflexive process controller. Process controllers regulate computation, and provide a reflexive description of their internal state and capabilities. Explicit models of context are used to assemble federations of processes for observing and predicting activity. As context changes, the federation is restructured. Restructuring the federation enables the system to adapt to a range of environmental conditions and to provide services that are appropriate over a range of activities.
G-tree: a new data structure for organizing multidimensional data (1994)

The author describes an efficient data structure called the G-tree (or grid tree) for organizing multidimensional data. The data structure combines the features of grids and B-trees in a novel manner. It also exploits an ordering property that numbers the partitions in such a way that partitions that are spatially close to one another in a multidimensional space are also close in terms of their partition numbers. This structure adapts well to dynamic data spaces with a high frequency of insertions and deletions, and to nonuniform distributions of data. We demonstrate that it is possible to perform insertion, retrieval, and deletion operations, and to run various range queries efficiently using this structure. A comparison with the BD tree, zkdb tree and the KDB tree is carried out, and the advantages of the G-tree over the other structures are discussed. The simulated bucket utilization rates for the G-tree are also reported.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
REAL-TIME TERRAIN RENDERING WITH INCREMENTAL LOADING FOR INTERACTIVE TERRAIN MODELLING (2011)

Terrains are an essential part of virtual environments in computer games, movies, visual impact studies, archi- tecture, urban design and archaeology. In order to render large terrains in real-time multi-resolution represen- tations are used. The underlying data structures are usually static and do not allow modification of the terrain in real-time. In recent years an increasing number of applications have been developed requiring interactive terrain modelling. In this paper we describe a real-time geometric clipmapping terrain rendering technique for large terrains which allows incremental updates of the underlying data structure. We have combined the method with an interactive sketch-based terrain modelling technique. The clipmap data structure is updated during runtime to synchronise the terrain visualization with changes to the underlying digital elevation map. Tests and examples demonstrate the advantages of our method over traditional approaches. Disadvantages and limitations are discussed and potential solutions for future work are presented.
Advances in Friction Stir Welding for Aerospace Applications (2006)

Friction stir welding (FSW), an innovative solid-state joining technique, is finding greater use in aerospace applications through advances in materials development evaluations, structural design and testing programmes, tooling and process innovations, and standards and specification developments. To advance FSW from the research stage into direct application, performance and properties data are needed. Therefore, the NIAR in Wichita, Kansas, began a multipronged approach to facilitate technology transfer of friction stir welding into production applications. Research programmes are focused on materials evaluations (e.g. corrosion resistance), structures evaluations, weld tool development, and process innovations. This article is an edited version of the expert paper and summarises the findings that were underpinned by detailed tests whose results were provided and are logged at WSU. A major conclusion is that significant advances continue to be made.
LATE MERISTEM IDENTITY2 acts together with LEAFY to activate <i>APETALA1</i> (2011)

The switch from producing vegetative structures (branches and leaves) to producing reproductive structures (flowers) is a crucial developmental transition that significantly affects the reproductive success of flowering plants. In Arabidopsis, this transition is in large part controlled by the meristem identity regulator LEAFY (LFY). The molecular mechanisms by which LFY orchestrates a precise and robust switch to flower formation is not well understood. Here, we show that the direct LFY target LATE MERISTEM IDENTITY2 (LMI2) has a role in the meristem identity transition. Like LFY, LMI2 activates AP1 directly; moreover, LMI2 and LFY interact physically. LFY, LMI2 and AP1 are connected in a feed-forward and positive feedback loop network. We propose that these intricate regulatory interactions not only direct the precision of this crucial developmental transition in rapidly changing environmental conditions, but also contribute to its robustness and irreversibility.

Solubility of Silica in Nitric Acid Solutions (1958)

The solubility and solution rates of porous glass and silica gel in nitric acid solutions at 95°, 65°, and 36° C. were determined. The solubility depends on the acid concentration, decreasing with increasing strength of free HNO 3 in accordance with the following equation: log C = ‐aN ‐ b , where C is the silica solubility, N is the acid normality, and a and b are empirical constants. The rate of solution of silica depends on acid concentration, the initial rate being a maximum at about 0.8 N. The amount of silica dissolved is a function of time and acid concentration. For short periods of time (1 to 40 hours) a maximum amount of silica is dissolved in about 0.8 N HNO 3 . For long periods of time this maximum is at 0.1 N or less. A curve showing the decrease in silica solubility with temperature in water is included.
Data Selection for Semi-Supervised Learning (2012)

The real challenge in pattern recognition task and machine learning process is to train a discriminator using labeled data and use it to distinguish between future data as accurate as possible. However, most of the problems in the real world have numerous data, which labeling them is a cumbersome or even an impossible matter. Semi-supervised learning is one approach to overcome these types of problems. It uses only a small set of labeled with the company of huge remain and unlabeled data to train the discriminator. In semi-supervised learning, it is very essential that which data is labeled and depend on position of data it effectiveness changes. In this paper, we proposed an evolutionary approach called Artificial Immune System (AIS) to determine which data is better to be labeled to get the high quality data. The experimental results represent the effectiveness of this algorithm in finding these data points.
