Robust Image Watermarking Based on Multiband Wavelets and Empirical Mode Decomposition (2007)

In this paper, we propose a blind image watermarking algorithm based on the multiband wavelet transformation and the empirical mode decomposition. Unlike the watermark algorithms based on the traditional two-band wavelet transform, where the watermark bits are embedded directly on the wavelet coefficients, in the proposed scheme, we embed the watermark bits in the mean trend of some middle-frequency subimages in the wavelet domain. We further select appropriate dilation factor and filters in the multiband wavelet transform to achieve better performance in terms of perceptually invisibility and the robustness of the watermark. The experimental results show that the proposed blind watermarking scheme is robust against JPEG compression, Gaussian noise, salt and pepper noise, median filtering, and ConvFilter attacks. The comparison analysis demonstrate that our scheme has better performance than the watermarking schemes reported recently.
Use of electrodynamic drivers in thermoacoustic refrigerators (2000)

Some issues involved in matching electrodynamic drivers to thermoacoustic refrigerators are examined using an equivalent circuit model. Conclusions are that the driver should be chosen to have a large product (Bl)2/(ReRm); the suspension stiffness should be chosen to make the combined impedance of the mechanical and acoustical parts of the system entirely real at the operating frequency; and the piston area should be selected to maximize electroacoustic efficiency, or other desired parameter, by matching the acoustic load to the optimum mechanical load for the particular driver. Alternately, if the piston area is fixed, the operating frequency can be adjusted to make this same match.
Bortezomib as an Antitumor Agent (2006)

The ubiquitin-proteasome pathway (UPP) is the major non-lysosomal proteolytic system in the cytosol and nucleus of all eukaryotic cells. Bortezomib (also known as PS-341 and Velcade) is a proteasome inhibitor, a novel class of cancer therapies. Bortezomib blocks multi-ubiquitinated protein degradation by inhibiting 26S proteasome activity, including regulating cell cycle, anti-apoptosis, and inflammation, as well as immune surveillance. In multiple myeloma (MM) cells, bortezomib directly induces cell stress response followed by activation of c-Jun NH(2) terminal kinase (JNK)/stress-activated protein kinase (SAPK), and triggers caspase-dependent apoptosis of tumor cells. Recent clinical studies demonstrated that bortezomib had remarkable anti-tumor activity in refractory and relapsed MM, providing the basis to approval by FDA. Its anti-tumor activities earlier in the course, in combination therapies, and in other malignancies is ongoing.
Integrating testing into the curriculum — arsenic in small doses (2001)

Testing accounts for 50% of the cost of software, yet it receives little treatment in most curricula. This paper presents some approaches to giving all students multiple, incremental exposures to software testing throughout the curriculum. A unifying framework is presented which identifies a minimal set of test experiences, skills and concepts students should accumulate. The integrated approach combines common test experiences in core courses, an elective course in software testing, and volunteer participation in a test laboratory.
ECM regulates MT1-MMP localization with β1 or αvβ3 integrins at distinct cell compartments modulating its internalization and activity on human endothelial cells (2002)

Regulation of membrane-type 1 matrix metalloproteinase (MT1-MMP) by different extracellular matrices (ECMs) on human endothelial cells (ECs) has been investigated. First, MT1-MMP is found at the intercellular contacts of confluent ECs grown on beta1 integrin-dependent matrix such as type 1 collagen (COL I), fibronectin (FN), or fibrinogen (FG), but not on gelatin (GEL) or vitronectin (VN). The novel localization of MT1-MMP at cell-cell contacts is assessed by confocal videomicroscopy of MT1-MMP-GFP-transfected ECs. Moreover, MT1-MMP colocalizes with beta1 integrins at the intercellular contacts, whereas it is preferentially found with alphavbeta3 integrin at motility-associated structures on migrating ECs. In addition, clustered integrins recruit MT1-MMP and neutralizing anti-beta1 or anti-alphav integrin mAb displace MT1-MMP from its specific sites, pointing to a biochemical association that is finally demonstrated by coimmunoprecipitation assays. On the other hand, COL I, FN, or FG up-regulate cell surface MT1-MMP on confluent ECs by an impairment of its internalization, whereas expression and internalization are not modified on GEL or VN. In addition, MT1-MMP activity is diminished in confluent ECs on COL I, FN, or FG. Finally, MT1-MMP participates and cooperates with beta1 and alphavbeta3 integrins in the migration of ECs on different ECM. These data show a novel mechanism by which ECM regulates MT1-MMP association with beta1 or alphavbeta3 integrins at distinct cellular compartments, thus modulating its internalization, activity, and function on human ECs.
Aeronautical Law Developments in 1940 (1940)

Three months later, another judge of the United States District Court, in the case of Morrell v. United Air Lines, in a suit arising out of the 1938 accident near Cleveland, held again that the United Air Lines could be sued in the State of New York.There seems, therefore, to be three decisions now, all contrary to the Dineen decision, and all by courts of higher authority, which appear to establish the rule that it is not necessary for an airline corporation to be actually operating the air line in a state to be subject to the jurisdiction of that state's court.Obviously, if the United Air Lines is successful in its present application to use the North Beach Airport as an' alternate terminus, the question will be academic rather than real.,It is, however, real in other instances.The United Air Lines has opened a ticket office in the City of St. Louis.Its nearest line is at Des Moines, Iowa.If the Missouri courts should follow these two federal decisions and the New York decision, then a person living in Missouri and having a cause of action against the United Air Lines could prosecute it in Missouri and would not have to go to a state where the company is actually operating.
A substrate-referenced data-conversion architecture (1991)

A substrate-referenced (SR) data-conversion architecture that operates with widely varying single polarity and or bipolar power supplies has been developed. By using well-established analog circuit design techniques and a novel substrate-referenced level-shifting scheme, digital switching noise on the noisiest power supply (V/sub dd/ in p-well CMOS) appears to the analog subsystem as a common-mode signal that is substantially rejected. Substrate-referenced successive-approximation weighted-capacitor analog-to-digital (A/D) converters have been implemented in p-well CMOS technology for several VLSI mixed-mode applications. A conventional ground-referenced converter was also integrated in the same technology for one specific application. With identical static logic circuitry on both chips, the SR architecture exhibited significantly higher accuracy than the conventional architecture.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Combined Posttransplant Prophylactic IVIg/Anti-CD 20/Plasmapheresis in Kidney Recipients With Preformed Donor-Specific Antibodies: A Pilot Study (2010)

This study raises the possibility that a more intensive day 0 prophylactic immunosuppressive strategy combining intravenous immunoglobulin/anti-CD20/plasmapheresis in this high-risk population, despite similar rates of early acute clinical humoral rejection, is associated with significant differences in long-term function and chronic AMR rate. Future prospective randomized studies are needed to assess the best strategies to be applied in light of the pretransplant immunologic risk stratification.
DHC: a density-based hierarchical clustering method for time series gene expression data (2003)

Clustering the time series gene expression data is an important task in bioinformatics research and biomedical applications. Recently, some clustering methods have been adapted or proposed. However, some concerns still remain, such as the robustness of the mining methods, as well as the quality and the interpretability of the mining results. In this paper, we tackle the problem of effectively clustering time series gene expression data by proposing algorithm DHC, a density-based, hierarchical clustering method. We use a density-based approach to identify the clusters such that the clustering results are of high quality and robustness. Moreover, the mining result is in the form of a density tree, which uncovers the embedded clusters in a data set. The inner-structures, the borders and the outliers of the clusters can be further investigated using the attraction tree, which is an intermediate result of the mining. By these two trees, the internal structure of the data set can be visualized effectively. Our empirical evaluation using some real-world data sets show that the method is effective, robust and scalable. It matches the ground truth provided by bioinformatics experts very well in the sample data sets.

A 20GB/s 1.8V 256MB DRAM is designed and fabricated using an 80nm CMOS process. An inductorless tetrahedral oscillator generates inherent quadrant phases combined with a cascaded pre-emphasis transmitter to achieve a 10Gbit/s/pin data rate.
In vivo anterior segment imaging in the rat eye with high speed white light full-field optical coherence tomography (2005)

We present a new high speed full-field optical coherence tomography (OCT) instrument, the first full-field OCT system that is capable of in vivo ocular imaging. An isotropic resolution of ~ 1 mum is achieved thanks to the use of a xenon arc lamp source and relatively high numerical aperture microscope objectives in a Linnik-type interferometer. Full-field illumination allows the capture of two-dimensional en face images in parallel, using a fast CMOS camera as detector array. Each en face image is acquired in a 4 ms period, at a maximum repetition rate of 250 Hz. Detection sensitivity per en face image is 71 dB. Higher sensitivity can be achieved by image correlation and averaging, although frame rate is reduced. We present the first preliminary results of in vivo imaging in the anterior segment of the rat eye, which reveal some cellular features in the corneal layers.
Exciting new advances in oral cancer diagnosis: avenues to early detection (2011)

The prognosis for patients with oral squamous cell carcinoma remains poor in spite of advances in therapy of many other malignancies. Early diagnosis and treatment remains the key to improved patient survival. Because the scalpel biopsy for diagnosis is invasive and has potential morbidity, it is reserved for evaluating highly suspicious lesions and not for the majority of oral lesions which are clinically not suspicious. Furthermore, scalpel biopsy has significant interobserver and intraobserver variability in the histologic diagnosis of dysplasia. There is an urgent need to devise critical diagnostic tools for early detection of oral dysplasia and malignancy that are practical, noninvasive and can be easily performed in an out-patient set-up. Diagnostic tests for early detection include brush biopsy, toluidine blue staining, autofluorescence, salivary proteomics, DNA analysis, biomarkers and spectroscopy. This state of the art review critically examines these tests and assesses their value in identifying oral squamous cell carcinoma and its precursor lesions.
Effect of Microaerosol Inhalation on the Pattern of Breathing (1975)

Microaerosol stimulation of the trachea and bronchi appears to have no effect on the pattern of breathing. However, laryngeal stimulation with microaerosol produces consistent changes characterized by slowing of the inspiratory effort. The reflex response can be abolished by either bilateral superior laryngeal nerve section or topical anesthesia of the laryngeal mucous membranes. Nasal stiumulation with saline microaerosol results in marked slowing of inspiration. This response can also be blocked by topical anesthesia of the nasal mucosa. The decreased breathing rate results from both increased t insp. and t exp. During inspiration the build-up phrenic discharge activity, the phrenic slope, decreases. The phrenic peak, however, remains unchanged. The nose and larynx, therefore, appear to play significant roles in the modification of the breathing pattern in response to a nonirritating solution delivered as a microaersol. Slower breathing, relexly produced in the human being by such a method, might benefit partial airway obstruction by reducing turbulence and therefore the work of breathing. It is speculated that in a marginally competent upper airway, this benefit might be a critical factor in survival.

STUDY ON MECHANICAL PROPERTIES AND MORPHOLOGY OF POLYOXYMETHYLENE TOUGHENED WITH IONOMERS (2003)

The mechanical properties and morphology of polyoxymethylene (POM) toughened with ionomers were investigated and the compatibilizing effect of methyl methacrylatestyrenebutadiene copolymer (MBS) on POM/ionomer blends was studied. It was found that 10% of ionomers could toughen POM. MBS plays the role as a compatibilizer and cooperative impact modifier for POM and ionomers, and the ternary blends achieve a remarkable improvement in impact strengh. The impact fracture surface demonstrated that a typical seaisland morphology for POM/ionomer binary blends. With the addition of MBS, the interface adhesion between POM and ionomers could be improved, and particle size of ionomer in POM matrix could be decreased, which impeded the growth of craze and promoted the shear deformation of POM matrix. As a result, a large amount of impact energy could be absorbed and the good toughening was thus obtained.
Molecular interactions of exogenous chemical agents with collagen—implications for tissue optical clearing (2006)

Reduction of optical scattering in turbid biological tissues using nonreactive chemical agents has potential applications for light-based diagnostics and therapeutics. Optical clearing effects by exogenous chemical agents, in particular sugars and sugar alcohols, have been found to be temporary with tissue rehydration. Applications with dermatologic laser therapies are now being investigated, but suffer from the inability of studied agents to penetrate the superficial layers of human skin. Selection, design, and refinement of topically effective chemical agents are hindered by a lack of fundamental understanding of tissue clearing mechanisms. We present recent work, particularly from the biochemistry community, detailing molecular interactions between chemical agents and collagen. This body of work demonstrates the perturbative effects of sugars and sugar alcohols on collagen high-order structures at micro- and nanometer length scales by screening noncovalent bonding forces. In addition, these studies emphasize the nonreactive nature of agent-collagen interactions and the ability of noncovalent bonding forces to recover with agent removal and drive reassembly of destabilized collagen structures. A mechanism of tissue optical clearing is proposed based on agent destabilization of high-order collagen structures.
Biochemical characterization of <i>Escherichia coli</i> DNA helicase I (1992)

The gene product of F tral is a bifunctional protein which nicks and unwinds the F plasmid during conjugal DNA transfer. Further biochemical characterization of the Tral protein reveals that it has a second, much lower, Km for ATP hydrolysis, in addition to that previously identified. Measurement of the single-stranded DNA-stimulated ATPase rate indicates that there is co-operative interaction between the enzyme monomers for maximal activity. Furthermore, 18O-exchange experiments indicate that Tral protein hydrolyses ATP with, at most, a low-level reversal of the hydrolytic step during each turnover.

On key distribution management for conditional access system on pay-TV system (1999)

A conditional access system (CAS) is essential in a pay-TV system to charge the subscriber the subscription fee, and key management is also important. Various levels of key hierarchy for a CAS are discussed and two methods of grouping the subscribers to reduce the complexity of key distributions are presented. Based on the proposed two grouping methods we proposed a simple and a complete scheme with four-levels of key hierarchy for the key distribution management CAS of the pay-TV system. We also analyze the performance of the proposed complete scheme. It is shown that our system is efficient and suitable for a pay-TV system which provides both pay per channel (PPC) and pay per view (PPV) services. Besides, the proposed complete scheme is also a flexible one for dynamic management. Finally, it should be noted that, though our discussion are focused on pay-TV only, our schemes are also suitable for a digital broadcasting system (DBS).
