A Comprehensive Survey on Three-Dimensional Mesh Watermarking (2008)

Three-dimensional (3-D) meshes have been used more and more in industrial, medical and entertainment applications during the last decade. Many researchers, from both the academic and the industrial sectors, have become aware of their intellectual property protection and authentication problems arising with their increasing use. This paper gives a comprehensive survey on 3-D mesh watermarking, which is considered an effective solution to the above two emerging problems. Our survey covers an introduction to the relevant state of the art, an attack-centric investigation, and a list of existing problems and potential solutions. First, the particular difficulties encountered while applying watermarking on 3-D meshes are discussed. Then we give a presentation and an analysis of the existing algorithms by distinguishing them between fragile techniques and robust techniques. Since attacks play an important role in the design of 3-D mesh watermarking algorithms, we also provide an attack-centric viewpoint of this state of the art. Finally, some future working directions are pointed out especially on the ways of devising robust and blind algorithms and on some new probably promising watermarking feature spaces.
Hardware-Based Event Stream Ordering for System-Level Observation Framework (2014)

The complexity of embedded systems presents key challenges in observing and analyzing complex hardware and software behavior. System-level observation methods provide in-situ monitoring and analysis of complex system behavior across hardware and software boundaries. Previous system-level observation methods utilized efficient pipelined hardware architectures that provide high throughput for reporting observed events but require significant area resources. Alternatively, an area-efficient round-robin priority-based event stream ordering technique significantly reduces area resources but requires tradeoffs in event stream throughput. We present a hardware-based event stream ordering technique capable of providing high throughput and flexibility in area requirements. This hardware-based event stream ordering technique reduces area requirements by 73.6% with a maximum reduction in event stream throughput of 4.6%.
Automatic Early Fault Detection for Rod Pump Systems (2011)

Abstract Typically, rod pump system failures are determined using the dynamometer card which may miss some early warnings. This paper presents a novel approach for early failure detection in rod pump wells using more than 14 parameters that indicate the daily functions of rod pump wells and employs advanced machine learning techniques. Our system recognizes failing, failed as well as normal situations by learning their patterns/signature from historical pump data, that include card area, peak-surface load, minimum-surface load, daily run-time, and production data. These data are automatically pre-processed using expert domain knowledge to reduce noise and to fill-in missing data. Our approach is novel in two ways. First, our machine learning algorithm AdaBNet uses boosting to learn several Bayesian Network models and then combines these models with different weights to form a stronger boosted model. Second, our approach generates this single boosted model that is applicable across all the wells in a field, as opposed to well-specific approaches that generate one model per well. This model detects anomalies, prefailure and failure signals and generates corresponding alerts. Early fault detection in rod pump wells is useful for automatic monitoring of large number of assets remotely, and could be extended to other artificial lift systems. We used a training data set of 12 wells to construct the learning model for the AdaBNet algorithm and tested the algorithm on 426 wells from the same field. The results show that our algorithm detects failures with accuracy higher than 90%. This framework can help field operators not only to remotely recognize and predict failures in advance, but also to help prioritize the available manpower, save significant time, reduce operating expense (OPEX), downtime and lost production. Early fault detection in rod pump systems can allow for proactive maintenance that can delay and even prevent future well failures. The proposed algorithm can enable production engineers remotely detect failures and anomalies before they occur, and assess the situation at control centers before taking any remedial or corrective actions. This approach to using a single model for an entire field is superior to other approaches with individual model for each well.
Propositional Satisfiability and Constraint Programming (2006)

Propositional Satisfiability (SAT) and Constraint Programming (CP) have developed as two relatively independent threads of research cross-fertilizing occasionally. These two approaches to problem solving have a lot in common as evidenced by similar ideas underlying the branch and prune algorithms that are most successful at solving both kinds of problems. They also exhibit differences in the way they are used to state and solve problems since SAT's approach is, in general, a black-box approach, while CP aims at being tunable and programmable. This survey overviews the two areas in a comparative way, emphasizing the similarities and differences between the two and the points where we feel that one technology can benefit from ideas or experience acquired from the other.
Analysis of the impact of process variations on clock skew (2000)

In this paper, we analyze the impact of process variations on the clock skew of VLSI circuits designed in deep submicrometer technologies. With smaller feature size, the utilization of a dense buffering scheme has been proposed in order to realize efficient and noise-immune clock distribution networks. However, the local variance of MOSFET electrical parameters, such as V/sub T/ and I/sub DSS/, increases with scaling of device dimensions, thus causing large intradie variability of the timing properties of clock buffers. As a consequence, we expect process variations to be a significant source of clock skew in deep submicrometer technologies. In order to accurately verify this hypothesis, we applied advanced statistical simulation techniques and accurate mismatch measurement data in order to thoroughly characterize the impact of intradie variations on industrial clock distribution networks. The comparison with Monte Carlo simulations performed by neglecting the effect of mismatch confirmed that local device variations play a crucial role in the design and sizing of the clock distribution network.
Gene Expression and Antimicrobial Activity of Bovine Macrophages in Response to <i>Mycobacterium avium</i> subsp. <i>paratuberculosis</i> (2004)

We evaluated gene expression and antimicrobial responses of bovine monocyte-derived macrophages incubated with Mycobacterium avium subsp. paratuberculosis (M. a. ptb), the causative agent of Johne's disease. Gene expression was evaluated by the use of human noncompetitive high-density oligonucleotide microarrays. Bovine messenger RNA hybridized with 14.2-18.2% of the 12,600 oligonucleotide probe sets. When macrophages incubated with M. a. ptb were compared with nonactivated control macrophages, macrophages activated by addition of interferon-gamma and lipopolysaccharide, and macrophages incubated with Mycobacterium avium subspecies avium (M. a. a), 47, 79, and 27 genes, respectively, were differentially expressed. Differential expression of six of these genes was confirmed using reverse transcriptase polymerase chain reaction. Several functional assays were performed to evaluate the potential relevance of differentially expressed genes to host defense. Macrophages phagocytizing M. a. a had a greater capacity to kill the organisms and to acidify phagosomes and a greater degree of apoptosis than did macrophages incubated with M. a. ptb. The results of these studies indicate that multiple genes and metabolic pathways are differentially expressed by macrophages ingesting mycobacterial organisms. Although the intracellular fate of mycobacterial organisms appears to be dependent on a complex interaction between macrophage and organism, phagosome acidification and apoptosis may play central roles in organism survival.
Impossibility of distributed consensus with one faulty process (1985)

The consensus problem involves an asynchronous system of processes, some of which may be unreliable. The problem is for the reliable processes to agree on a binary value. In this paper, it is shown that every protocol for this problem has the possibility of nontermination, even with only one faulty process. By way of contrast, solutions are known for the synchronous case, the “Byzantine Generals” problem.
Functional Genetic Analysis of Rhesus Cytomegalovirus: Rh01 Is an Epithelial Cell Tropism Factor (2007)

Rhesus cytomegalovirus (RhCMV) is an emerging model for human cytomegalovirus (HCMV) pathogenesis that facilitates experimental CMV infection of a natural primate host closely related to humans. We have generated a library of RhCMV mutants with lesions in genes whose HCMV orthologues have been characterized as nonessential for replication in human fibroblasts, and we characterized their replication in rhesus fibroblasts and epithelial cells. The RhCMV mutants grew well in fibroblasts, as predicted by earlier studies with HCMV. However, mutations in four genes caused replication defects in rhesus retinal pigment epithelial cells: Rh01 (an HCMV TRL1 orthologue), Rh159 (HCMV UL148), Rh160 (HCMV UL132), and Rh203 (HCMV US22). Growth of the Rh01-deficient mutant was examined in detail. After entry into epithelial cells, the mutant expressed representative viral proteins, accumulated viral DNA, and generated infectious virus, but it failed to spread efficiently. We conclude that Rh01 is a cell tropism determinant that has the potential to dramatically affect virus spread and pathogenesis.
Optical properties of human sclera, and their consequences for transscleral laser applications (1991)

The spectral dependence of the optical properties of human sclera adjacent to the limbus was investigated and related to the potentials of transscleral photocoagulation. The total transmission, absorption, and reflection, as well as the angular distribution of the transmitted and reflected light were measured at five laser wavelengths (442 nm, 514 nm, 633 nm, 804 nm, and 1,064 nm), both for noncontact and contact applications. Absorption and scattering coefficients were determined using the Kubelka-Munk model for light propagation through a scattering tissue. The scleral transmission is only 6% at 442 nm but increases to 35% at 804 nm and to 53% at 1,064 nm. The absorption is high at short wavelengths with 40% at 442 nm but it is only 6% at 804 nm and 1,064 nm. The reflection is generally higher than 40% and shows little wavelength dependence. The transmitted light is scattered diffusely at short wavelengths, but at 804 nm and 1,064 nm it exhibits a fairly narrow angular distribution in forward direction. Fiber contact leads to an increase of transmission, with a factor of 3.5 at 442 nm, of 2.0 at 804 nm, and 1.5 at 1,064 nm. Our results indicate that the diode laser (804 nm) and the Nd:YAG laser (1,064 nm) with contact delivery are best suited for transscleral photocoagulation.
Turbuhaler®: a new device for dry powder terbutaline inhalation (1988)

The aim of this study was to compare bronchodilator response and adverse effects of terbutaline when administered with the metered dose inhaler (MDI) Bricanyl and with the dry powder inhaler Bricanyl Turbuhaler (BT). Nine adult patients with bronchial asthma participated. The study was of an open crossover design. At 30-min intervals the patients inhaled increasing doses of terbutaline (0.25 mg to 5.0 mg cumulated) from either the conventional MDI or from the BT. After each inhalation FEV1, FVC, heart rate, muscle tremor and adverse effects were recorded. Both treatments, BT and MDI, resulted in a dose-related increase in lung function, without any statistical difference. Taste sensation, muscle tremor and increase in heart rate were observed in both groups. Because of the design of the BT one may assume that inhalation failure can be avoided.
Laser‐interferometry‐based tracking for dynamic measurements (1998)

The accurate measurement of the position and orientation of a robot end‐effector is the most critical issue for calibrating of robotic devices. Calibration methods provide tools to improve the accuracy of robots without modification to the mechanical unit or its control architecture. However, such calibration techniques require a large number of measurements. Dynamic measurement of position and orientation not only provides a solution to this problem, it also establishes the foundation for development of techniques to improve the robot’s dynamic accuracy. The concept of laser‐interferometry‐based measurement has been proposed. A system based on this concept is generally referred to as a laser tracking system (LTS). This paper describes the principle of laser‐interferometry‐based tracking. Further, the structure and various components within such a system are presented. A kinematic model for laser tracking is described and the performance of the system in its present configuration is presented. The application potential of such an approach to position and orientation (pose) measurement is also briefly described.
M-CAT Binding Factor, a Novel <i>trans</i> -Acting Factor Governing Muscle-Specific Transcription (1990)

The cardiac troponin T (cTNT) promoter contains a highly muscle specific distal promoter element capable of conferring muscle-specific transcription from a heterologous TATA box-transcription initiation site. Three sequence motifs within this distal promoter element are conserved in the promoter and regulatory regions of many sarcomeric protein genes. Mutational analysis demonstrated that homologies to two of these conserved motifs (CArG/CBAR and MEF 1) were not required for activity of cTNT promoter-marker gene constructs in transfected embryonic skeletal muscle cells. In contrast, disruption of either or both copies of the conserved M-CAT motif (5'-CATTCCT-3') inactivated the cTNT promoter in these cells. Both M-CAT motifs were protected from DNase I cleavage in solution footprint assays by an M-CAT binding factor (MCBF) present in nuclear extracts from embryonic muscle tissue. M-CAT mutations that inactivated the cTNT promoter also disrupted MCBF binding, indicating that MCBF may be a key trans-acting factor required for muscle-specific expression of the cTNT promoter. MCBF also bound to the M-CAT motif in the distal promoter region of the skeletal alpha-actin gene, suggesting that it may play a role in the regulation of this and perhaps other muscle genes that contain M-CAT motifs.
On the effects of dimensionality reduction on high dimensional similarity search (2001)

The dimensionality curse has profound effects on the effectiveness of high-dimensional similarity indexing from the performance perspective. One of the well known techniques for improving the indexing performance is the method of dimensionality reduction. In this technique, the data is transformed to a lower dimensional space by finding a new axis-system in which most of the data variance is preserved in a few dimensions. This reduction may also have a positive effect on the quality of similarity for certain data domains such as text. For other domains, it may lead to loss of information and degradation of search quality. Recent research indicates that the improvement for the text domain is caused by the re-enforcement of the semantic concepts in the data. In this paper, we provide an intuitive model of the effects of dimensionality reduction on arbitrary high dimensional problems. We provide an effective diagnosis of the causality behind the qualitative effects of dimensionality reduction on a given data set. The analysis suggests that these effects are very data dependent. Our analysis also indicates that currently accepted techniques of picking the reduction which results in the least loss of information are useful for maximizing precision and recall, but are not necessarily optimum from a qualitative perspective. We demonstrate that by making simple changes to the implementation details of dimensionality reduction techniques, we can considerably improve the quality of similarity search.

Critical micelle concentrations of aqueous surfactant systems (1971)

Abstract : Critical micelle concentrations (CMC's) have been collected, organized and evaluated. The literature has been scanned for numerical values from 1926 up to and including 1966. In addition, over 800 values, hitherto available in graphical form or implied in experimental data, have been extracted from the publications and are included. Close to 5,000 entries, based on 333 references, dealing with 720 compounds are tabulated in the main tables. Whenever available, the temperature, any additives present, the method of determination and the literature source are given for each CMC value and an indication of the apparent quality of the preparation and method used are included. A shorter table gives selected values which are believed to be particularly reliable, including highly accurate ones. Among these, concordant values from at least two independent laboratories are emphasized. Included in the Introduction is a general discussion of the importance and significance of CMC values and of methods for their determination, as well as a summary of the procedures used in the collection, evaluation and presentation of these values in the present work. Extensive indexes are provided. (Author)
Constrained motion control of multisegment continuum robots for transurethral bladder resection and surveillance (2013)

Constrained motion control of robotic end-effectors is essential for safe operation in confined spaces such as the urinary bladder. This paper presents the clinical motivation for the development of new control algorithms for robotic-assisted transurethral bladder resection and surveillance using multisegment continuum robots. The anatomy, workspace, and access constraints for this procedure are identified and used as a guideline for the design of the telesurgical system and its control architecture. Constraints are mapped into the configuration space of the robot rather than in task space simplifying the modeling and the enforcement of virtual fixtures. The redundancy resolution is autonomously modified in order to exploit the remaining degrees of freedom using task priority. These methods are validated on a glass model of urinary bladder.
Inverted GaInP / (In)GaAs / InGaAs triple-junction solar cells with low-stress metamorphic bottom junctions (2008)

We demonstrate high efficiency performance in two ultra-thin, Ge-free III–V semiconductor triple-junction solar cell device designs grown in an inverted configuration. Low-stress metamorphic junctions were engineered to achieve excellent photovoltaic performance with less than 3 × 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">6</sup> cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">−2</sup> threading dislocations. The first design with band gaps of 1.83/1.40/1.00 eV, containing a single metamorphic junction, achieved 33.8% and 39.2% efficiencies under the standard one-sun global spectrum and concentrated direct spectrum at 131 suns, respectively. The second design with band gaps of 1.83/1.34/0.89 eV, containing two metamorphic junctions achieved 33.2% and 40.1% efficiencies under the standard one-sun global spectrum and concentrated direct spectrum at 143 suns, respectively.
Single multimode fiber endoscope (2017)

Multimode fibers can guide thousands of modes capable of delivering spatial information. Unfortunately, mode dispersion and coupling have so far prevented their use in endoscopic applications. To address this long-lasting challenge, we present a robust scanning fluorescence endoscope. A spatial light modulator shapes the input excitation wavefront to focus light on the distal tip of the fiber and to rapidly scan the focus over the region of interest. A detector array collects the fluorescence emission propagated back from the sample to the proximal tip of the fiber. We demonstrate that proper selection of the multimode fiber is critical for a robust calibration and for high signal-to-background ratio performance. We compare different types of multimode fibers and experimentally show that a focus created through a graded-index fiber can withstand a few millimeters of fiber distal tip translation. The resulting scanning endoscopic microscope images fluorescent samples over a field of view of 80µm with a resolution of 2µm.
A Client Focussed Response to an Industry Training Need (1999)

The Apprentice Intensive Skills Training [AIST] program was created, developed and implemented in response to client demand for apprentices to be more immediately useful in a specific workplace - as compared to those entering this same workplace without the benefit of any relevant knowledge, skills and attitudes. Program content was derived from competency based modules and complemented with hand skills development, exercises developed by Karratha College staff. The program has been successful in commercial, academic and customer satisfaction contexts.
REELIN and Schizophrenia:: A Disease at the Interface of the Genome and the Epigenome (2002)

The downregulation of the Reelin gene (RELN) that occurs in schizophrenic brains, which are characterized by pyramidal neurons with shortened dendrites and by reduced expression densities of dendritic spines, may well result from hypermethylation of the RELN promoter. In the adult mammalian brain, gamma-aminoburytic acid-secreting (GABAergic) interneurons release RELN into the extracellular matrix, where it binds with high affinity to the integrin receptors present at dendritic spine postsynaptic densities and likely plays a role, elaborated in this article, in synaptic plasticity. In heterozygous reeler mice, which are haploinsufficient in RELN, inhibitors of histone deacetylase increase DNA demethylase activity and restore RELN expression. Such inhibitors could thus be of therapeutic value in mitigating vulnerability to schizophrenia among high-risk individuals.
