A toolbox of mechanisms for robust and scalable service discovery in mobile ad-hoc networks (2007)

Scenarios for scalable and robust service discovery in MANETs differ vastly with respect to their basic conditions. Basic conditions, for example, are field size, level of mobility and number of nodes. Depending on context and scenario, a number of mechanisms for scalable and robust service discovery in MANETs were and are in discussion. This paper assigns service discovery solutions to scenario requirements and presents the performance of the hybrid concept Hydra. Hydra uses multiple basic mechanisms for service discovery that were combined to simultaneously fulfill the requirements for robustness, scalability and high service dynamics. The paper finishes with the vision of a scenario-independent service discovery toolbox for MANETs: Context parameters are controlled automatically and basic mechanisms can be exchanged as needed.

Linear Mixed-Effects Models: Applications to the Behavioral Sciences and Adolescent Community Health (2012)

In a double-blind controlled study, six infants with congestive heart failure were given captopril to observe the effect on blood pressure. There was a significant fall in systolic (P less than 0.02) and diastolic (P less than 0.01) blood pressure at 90 minutes after the first dose. There was no correlation with plasma renin activity or plasma sodium concentration. The need to monitor blood pressure after introduction of captopril therapy for the treatment of heart failure in infants is demonstrated.
Production of citric acid by Aspergillus niger using cane molasses in a stirred fermentor (2002)

The present investigation deals with the kinetics of submerged citric acid fermentation by Aspergillus niger using blackstrap molasses as the basal fermentation media. A laboratory scale stirred fermentor of 15-L capacity having working volume of 9-L was used for cultivation process and nutritional analysis. Among the 10 stock cultures of Aspergillus niger , the strain GCBT7 was found to enhance citric acid production. This strain was subjected to parametric studies. Major effects were caused due to oxygen tension (1.0 l/l/min), pH value (6.0) and incubation temperature (30ºC). All fermentations were carried out following the growth on 150 g/l raw molasses sugars for 144 hours. Ferrocyanide (200 ppm) was used to control the trace metals present in the molasses medium. Ammonium nitrate (0.2%) was added as nitrogen source. Maximum citric acid production (99.56 ± 3.5a g/l) was achieved by Aspergillus niger GCBT7. The dry cell mass and sugar consumption were 18.5 and 96.55 g/l, respectively. The mycelia were intermediate round pellets in their morphology. The specific productivity of GCBT7 (qp = 0.074 ± 0.02a g/g cells/h) was several folds higher than other strains. The specific production rate and growth coefficient revealed the hyperproducibility of citric acid using mutant GCBT7.
A methodology for integration of heterogeneous databases (1994)

The transformation of existing local databases to meet diverse application needs at the global level is performed through a four-layered procedure that stresses total schema integration and virtual integration of local databases. The proposed methodology covers both schema integration and database integration, and uses a four-layered schema architecture (local schemata, local object schemata, global schema, and global view schemata) with each layer presenting an integrated view of the concepts that characterize the layer below. Mechanisms for accomplishing this objective are presented in theoretical terms, along with a running example. Object equivalence classes, property equivalence classes, and other related concepts are discussed in the context of logical integration of heterogeneous schemata, while object instance equivalence classes and property instance equivalence classes, and other related concepts are discussed for data integration purposes. The proposed methodology resolves naming conflicts, scaling conflicts, type conflicts, and level of abstraction, and other types of conflicts during schema integration, and data inconsistencies during data integration.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
DC-PCM: Mitigating PCM Write Disturbance with Low Performance Overhead by Using Detection Cells (2019)

As DRAM scaling becomes ever more difficult, Phase Change Memory (PCM) is attracting attention as a new memory or storage class memory. Unfortunately, PCM cell data can be changed by frequently writing `0' to adjacent cells. This phenomenon is called Write Disturbance (WD). To mitigate WD errors with low performance overhead, we propose a Detection Cell PCM (DC-PCM). In the DC-PCM, additional cells called Detection Cells (DC) are allocated to a memory-line to pre-detect WD errors. For pre-detection, we propose schemes that give DCs higher WD-vulnerability than normal cells. However, additional time is needed to verify DCs. To hide the time needed to perform the verifications during a WRITE, DC-PCM enables the local word-lines of DCs to operate independently (Decoupled Word-line), and verifies different directions in parallel (Parallel DC-Verification). After verification, the DC-PCM increases the WD-vulnerability of the DCs, or restores the memory-line data (DC-Correction). In our simulation, DC-PCMs showed performance comparable to a WD-free PCM for all workloads.
Immunotherapy of chronic lymphocytic leukemia (2001)

Chronic lymphocytic leukemia (CLL) is typically an indolent B-cell malignancy, primarily affecting the aging population. Standard cytotoxic treatment with alkylating agents or purine analogs is very effective at inducing remission. However, curative treatment is not yet available. Immunotherapy is emerging as an exciting modality with significant potential to advance the treatment of this disease. This review discusses the different modalities of immunotherapy under investigation for the treatment of CLL. These modalities include passive immunotherapy with monoclonal antibodies against antigens on CLL B-cells including CD52 and CD20. Active immunotherapy by vaccination with genetically modified autologous leukemia cells is being evaluated in clinical trials. Allogeneic stem cell transplant for adoptive immunotherapy of CLL is yet another modality being investigated. While this modality may have limited application due to morbidity in older patients, it may result in improved survival and possibly cure. The use of immunotherapy in CLL is in the early stages of development. It is likely that this approach will significantly improve the treatment of CLL and possibly contribute to the cure of this disease.
Anomaly Detection with HTM (2016)

We model information and communications technology (ICT) systems as complex adaptive systems. Since we cannot hope to predict all future incidents in complex systems, real-time monitoring is needed to detect local failures before they propagate into global failures with an intolerable impact. In particular, monitoring is required to determine the consequences of injecting artificial errors into production systems and to learn how to avoid or limit the impact of future incidents.
Useful signals from motor cortex (2007)

Historically, the motor cortical function has been explained as a funnel to muscle activation. This invokes the idea that motor cortical neurons, or 'upper motoneurons', directly cause muscle contraction just like spinal motoneurons. Thus, the motor cortex and muscle activity are inextricably entwined like a puppet master and his marionette. Recently, this concept has been challenged by current experimentation showing that many behavioural aspects of action are represented in motor cortical activity. Although this activity may still be related to muscle activation, the relation between the two is likely to be indirect and complex, whereas the relation between cortical activity and kinematic parameters is simple and robust. These findings show how to extract useful signals that help explain the underlying process that generates behaviour and to harness these signals for potentially therapeutic applications.
SEGMENTATION OF UAV-BASED IMAGES INCORPORATING 3D POINT CLOUD INFORMATION (2015)

Abstract. Numerous applications related to urban scene analysis demand automatic recognition of buildings and distinct sub-elements. For example, if LiDAR data is available, only 3D information could be leveraged for the segmentation. However, this poses several risks, for instance, the in-plane objects cannot be distinguished from their surroundings. On the other hand, if only image based segmentation is performed, the geometric features (e.g., normal orientation, planarity) are not readily available. This renders the task of detecting the distinct sub-elements of the building with similar radiometric characteristic infeasible. In this paper the individual sub-elements of buildings are recognized through sub-segmentation of the building using geometric and radiometric characteristics jointly. 3D points generated from Unmanned Aerial Vehicle (UAV) images are used for inferring the geometric characteristics of roofs and facades of the building. However, the image-based 3D points are noisy, error prone and often contain gaps. Hence the segmentation in 3D space is not appropriate. Therefore, we propose to perform segmentation in image space using geometric features from the 3D point cloud along with the radiometric features. The initial detection of buildings in 3D point cloud is followed by the segmentation in image space using the region growing approach by utilizing various radiometric and 3D point cloud features. The developed method was tested using two data sets obtained with UAV images with a ground resolution of around 1-2 cm. The developed method accurately segmented most of the building elements when compared to the plane-based segmentation using 3D point cloud alone.
The Biological Collections in CSIRO: a National Heritage? (2004)

From the organization's earliest days, several Divisions of CSIRO have assembled substantial collections of biological species. These include a wide variety of plants and animals. Some collections consist of live organisms, some of preserved material. The origins and the functions of the collections vary; most of them now contain material of considerable value. Their history is intriguing, and their future has continued to be a question of importance.
System identification using Kautz models (1994)

In this paper, the problem of approximating a linear time-invariant stable system by a finite weighted sum of given exponentials is considered. System identification schemes using Laguerre models are extended and generalized to Kautz models, which correspond to representations using several different possible complex exponentials. In particular, linear regression methods to estimate this sort of model from measured data are analyzed. The advantages of the proposed approach are the simplicity of the resulting identification scheme and the capability of modeling resonant systems using few parameters. The subsequent analysis is based on the result that the corresponding linear regression normal equations have a block Toeplitz structure. Several results on transfer function estimation are extended to discrete Kautz models, for example, asymptotic frequency domain variance expressions.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Regulation of vascular cell adhesion molecule 1 on human dermal microvascular endothelial cells (1992)

Vascular endothelial cell adhesion molecule 1 (VCAM-1) is an adherence molecule that is induced on endothelial cells by cytokine stimulation and can mediate binding of lymphocytes or tumor cells to endothelium. Because these interactions often occur at the level of the microvasculature, we have examined the regulation of expression of VCAM-1 in human dermal microvascular endothelial cells (HDMEC) and compared it to the regulation of VCAM-1 in large vessel human umbilical vein endothelial cells (HUVEC). Both cell populations were judged pure as assessed by expression of von Willebrand factor and uptake of acetylated low density lipoprotein. Expression of VCAM-1 was not detectable on either unstimulated HDMEC or HUVEC when assessed by ELISA or flow cytometry. Stimulation of either HDMEC or HUVEC with TNF-alpha resulted in a time- and dose-dependent induction of VCAM-1. However, although TNF-alpha-induced cell surface and mRNA expression of VCAM-1 in HDMEC was transient, peaking after 16 h of stimulation, TNF stimulation led to persistently elevated cell surface expression of VCAM-1 on HUVEC. IL-1 alpha also induced cell surface expression of VCAM-1 on HUVEC in a time- and dose-dependent manner, but stimulation of HDMEC with IL-1 alpha at doses up to 1000 U/ml failed to induce significant cell surface expression. However, IL-1 alpha induced time- and dose-dependent increases in ICAM-1 on HDMEC. Similarly, IL-4 induced VCAM-1 expression and augmented TNF-alpha-induced expression on HUVEC but did not affect VCAM-1 expression on HDMEC. Binding of Ramos cells to cytokine-stimulated endothelial cell monolayers correlated with VCAM-1 induction. Increased binding was seen after stimulation of HDMEC with TNF-alpha, which was blocked by anti-VCAM-1 mAb, but no increases in binding were noted after stimulation of HDMEC monolayers with IL-1 alpha. These data provide additional evidence for the existence of endothelial cell heterogeneity and differences in cell adhesion molecule regulation on endothelial cells derived from different vascular beds.
An Underwater audio communicator (1966)

There is a growing need for voice communications underwater between divers and between divers and surface vessels. This paper discusses the general problem in terms of system analysis. The authors decided to direct their efforts toward the low-cost, volume market of the sport and commercial diver. A communicator for this purpose must be simple, reliable, and low in cost. Hydrotalk, the result of their development, radiates an omnidirectional, audio acoustical wave through the water medium. Reception is accomplished by the listening diver's unaided ear. A large part of the development involved the creation of an improved underwater transducer, having a high coefficient of coupling between its signal input current and the sound power produced in the water. While this device represents a real step forward in solving the underwater communications problem, the authors are aware that more work needs to be done in improving intelligibility of the voice signal input to the microphone. This will probably be in the direction of a simple and safe full-face diving mask, which will provide a common chamber for the nose and mouth in which to mount the microphone. The authors are continuing their development work along these lines.

Evaluation of N-grams conflation approach in text-based information retrieval (2005)

This paper examines a conflation method based on the N-grams approach and evaluates its performance relative to the results achieved by other techniques such as Porter algorithm and successor variety stemming. In addition to that, an alternative way of enhancing the N-grams method, derived from the concept of inverse frequency weighing, is introduced and evaluated. The experimental results generated using standard collections ADI, CISI and Medlars show a consistent improvement over the traditional conflation methods, as well as demonstrate the viability of the introduced inverse fvequency multiplier technique.

Initial Testing of the CST-100 Aerodynamic Deceleration System (2013)

NASA’s Commercial Crew Development (CCDev) initiative is providing the opportunity for the Boeing Company to complete the preliminary design of the CST-100 spacecraft and Commercial Crew Transportation System (CCTS). Demonstration of key system concepts, technologies, risk reductions, and procurement of long lead items are also being completed. The CST-100 is designed to affordably, reliably, and safely transfer crew from the Earth's surface to orbiting space complexes in low earth orbit, including the International Space Station and the Bigelow Space Complex. NASA’s investment in CCDEV, coupled with Boeing’s own resources, has allowed significant progress to be made toward providing a commercial LEO transportation service by 2016.
Winding mandrel design for the wide cable SSC dipole (1991)

The 50-mm coil (i.d.) Superconducting Super Collider (SSC) dipole magnets use wider cables to give a greater operational margin between the quench field and the operating field. The cable used for the inner coil has 30 strands of the same size (0.808 mm) instead of 23, the outer has 36 strands of the same size (0.648 mm) instead of 30, and the cable widths are increased in proportion. Although the inner diameter of the coil has been increased from 40 mm, the coil ends are noticeably harder to wind. The authors describe the computational and experimental effort to design winding mandrels or center posts for the constant-perimeter ends.
In Vitro Synergy of Caspofungin and Amphotericin B against <i>Aspergillus</i> and <i>Fusarium</i> spp (2002)

We investigated the in vitro interaction of caspofungin and amphotericin B for clinical isolates of Aspergillus and FUSARIUM: Synergy tests were performed using the checkerboard method and following the NCCLS M38-P guidelines in Antibiotic Medium 3 broth supplemented to 2% glucose. Antagonism was not observed for any of the isolates tested. Caspofungin and amphotericin B were synergistic or synergistic to additive for at least half of the isolates.
Isolation of <i>Mycoplasma bovis</i> from bovine clinical samples in the Republic of Ireland (2001)

Mycoplasma bovis was detected in 134 (18 per cent) of 736 samples of bovine lung tissue collected from fatal pneumonia cases in the Republic of Ireland between April 1995 and December 1998. The cases occurred in 95 herds and recurred in four of them. Other respiratory pathogens were identified in 66 per cent of the M bovis-positive cases, with Pasteurella species, infectious bovine rhinotracheitis and parainfluenza 3 virus being most frequently detected. Mastitis and arthritis were less common clinical signs associated with M bovis infection; 22 cases of M bovis mastitis and five cases of M bovis arthritis were diagnosed in five herds.
Chemical Interactions of Polyethylene Glycols (PEGs) and Glycerol with Protein Functional Groups: Applications to Effects of PEG and Glycerol on Protein Processes (2015)

In this work, we obtain the data needed to predict chemical interactions of polyethylene glycols (PEGs) and glycerol with proteins and related organic compounds and thereby interpret or predict chemical effects of PEGs on protein processes. To accomplish this, we determine interactions of glycerol and tetraEG with >30 model compounds displaying the major C, N, and O functional groups of proteins. Analysis of these data yields coefficients (α values) that quantify interactions of glycerol, tetraEG, and PEG end (-CH2OH) and interior (-CH2OCH2-) groups with these groups, relative to interactions with water. TetraEG (strongly) and glycerol (weakly) interact favorably with aromatic C, amide N, and cationic N, but unfavorably with amide O, carboxylate O, and salt ions. Strongly unfavorable O and salt anion interactions help make both small and large PEGs effective protein precipitants. Interactions of tetraEG and PEG interior groups with aliphatic C are quite favorable, while interactions of glycerol and PEG end groups with aliphatic C are not. Hence, tetraEG and PEG300 favor unfolding of the DNA-binding domain of lac repressor (lacDBD), while glycerol and di- and monoethylene glycol are stabilizers. Favorable interactions with aromatic and aliphatic C explain why PEG400 greatly increases the solubility of aromatic hydrocarbons and steroids. PEG400-steroid interactions are unusually favorable, presumably because of simultaneous interactions of multiple PEG interior groups with the fused ring system of the steroid. Using α values reported here, chemical contributions to PEG m-values can be predicted or interpreted in terms of changes in water-accessible surface area (ΔASA) and separated from excluded volume effects.
Parameters affecting microwave‐assisted extraction of withanolides (2001)

Focused microwave-assisted extraction was applied to the extraction of three main withanolides from airdried leaves of Iochroma gesnerioides, namely, withaferin A, iochromolide and withacnistin. Six extraction variables, i.e. nature and volume of extracting solvent, sample moisture, extraction time, power of irradiation and particle size, were investigated with respect to the recovery of withanolides. The most favourable conditions were obtained by using powdered plant material (< 220 microns), previously impregnated with water for 15 min, and extracted with methanol for 40 s at 25 W. The results obtained using the optimised method were compared to those achievable with Soxhlet extraction.
