Load Impedance Measurement on a Coaxial Cable via Time-Frequency Domain Reflectometry (2006)

In this paper, a new signal processing based methodology which is able to measure a load impedance with high accuracy and resolution is implemented. This methodology is characterized by a chirp signal with Gaussian envelope which enables one to achieve time localization and to assign energy in the frequency band of interest at the same time. For an evaluating the reflection coefficient and estimating the fault distance on a cable a normalized time-frequency cross-correlation function is utilized, and a cross time-frequency distribution function is used to acquire the phase difference between the input and the reflected signals. The real impedance measurement experiments have been carried out using a time-frequency domain reflectometry (TEDR) system on a coaxial cable with various sorts of terminal resistors. The experimental results of the TEDR based impedance measurement are compared with those of the commercial time domain reflectometry (TDR). The proposed TEDR based impedance measurement methodology shows that it is able to evaluate the location of fault on a coaxial cable and it can offers information of the fault as the load impedance

Characterization of human epiplakin: RNAi-mediated epiplakin depletion leads to the disruption of keratin and vimentin IF networks (2005)

Epiplakin is a member of the plakin family with multiple copies of the plakin repeat domain (PRD). We studied the subcellular distribution and interactions of human epiplakin by immunostaining, overlay assays and RNAi knockdown. Epiplakin decorated the keratin intermediate filaments (IF) network and partially that of vimentin. In the binding assays, the repeat unit (PRD plus linker) showed strong binding and preferentially associated with assembled IF over keratin monomers. Epiplakin knockdown revealed disruption of IF networks in simple epithelial but not in epidermal cells. In rescue experiments, the repeat unit was necessary to prevent the collapse of IF networks in transient knockdown; however, it could only partially restore the keratin but not the vimentin IF network in stably knocked down HeLa cells. We suggest that epiplakin is a cytolinker involved in maintaining the integrity of IF networks in simple epithelial cells. Furthermore, we observed an increase of epiplakin expression in keratinocytes after the calcium switch, suggesting the involvement of epiplakin in the process of keratinocyte differentiation.
High‐Flux Signals and Spatial Localization in High‐Resolution <sup>1</sup>H Spectroscopy with Surface Coils (1989)

To perform in vivo localized proton spectroscopy with water suppression, spin-echo sequences, made of binomial pulses, are commonly used with surface coils. The frequency selective response to such a sequence is also-spatially dependent, that is dependent on the sample shape and on the pulse angle adjustment. It is consequently pointed out in this paper that quantitative analysis for relative peak intensities may be strongly affected by the contribution of the high-flux regions. In vivo proton spectroscopy of rat brain exemplifies this difficulty. It is shown that the use of selective prepulses to suppress high-flux signals may be of poor efficiency depending on chemical shift, while the use of hard nonselective prepulses works for any chemical shift.
Functional and evolutionary genomics of <i>Mycobacterium tuberculosis</i> : Insights from genomic deletions in 100 strains (2004)

To better understand genome function and evolution in Mycobacterium tuberculosis, the genomes of 100 epidemiologically well characterized clinical isolates were interrogated by DNA microarrays and sequencing. We identified 68 different large-sequence polymorphisms (comprising 186,137 bp, or 4.2% of the genome) that are present in H37Rv, but absent from one or more clinical isolates. A total of 224 genes (5.5%), including genes in all major functional categories, were found to be partially or completely deleted. Deletions are not distributed randomly throughout the genome but instead tend to be aggregated. The distinct deletions in some aggregations appear in closely related isolates, suggesting a genomically disruptive process specific to an individual mycobacterial lineage. Other genomic aggregations include distinct deletions that appear in phylogenetically unrelated isolates, suggesting that a genomic region is vulnerable throughout the species. Although the deletions identified here are evidently inessential to the causation of disease (they are found in active clinical cases), their frequency spectrum suggests that most are weakly deleterious to the pathogen. For some deletions, short-term evolutionary pressure due to the host immune system or antibiotics may favor the elimination of genes, whereas longer-term physiological requirements maintain the genes in the population.
Azithromycin Retards <i>Pseudomonas aeruginosa</i> Biofilm Formation (2004)

Using a flow cell biofilm model, we showed that a sub-MIC of azithromycin (AZM) can delay but not inhibit Pseudomonas aeruginosa biofilm formation and results in the development of a stable AZM resistance phenotype. Furthermore, mature biofilms were not affected by AZM.
Osteosarcoma: a comprehensive review (2018)

Osteosarcoma (OS) is a relatively rare tumor of bone with a worldwide incidence of 3.4 cases per million people per year. For most of the twentieth century, five-year survival rates for classic OS were very low. In the 1970s, the introduction of adjuvant chemotherapy in the treatment of OS increased survival rates dramatically. The current article reviews the various types of OS and analyzes the clinical and histological features. We also examine historical and current literature to present a succinct review of methods for diagnosis and staging, as well as treatment, and we also discuss some of the future directions of treatment.
On Disparity Matching in Stereo Vision via a Neural Network Framework (1999)

This paper presents a neural framework for dealing with the problem of disparity matching in stereo vision. Two different types of neural networks are used in this framework: one is called the vitality conservation (VC) network for learning clustering, and the other is the back-propagation (BP) network for learning disparity matching. The VC network utilizes a vitality conservation principle to facilitate self-development in network growing. The training process of VC is smooth and incremental; it not only achieves the biologically plausible learning property, but also facilitates systematic derivations for training parameters. Using the [intensity, variation, orientation, x, y] of each pixel (or a block) as the training vector, the VC network dismembers the input image into several clusters, and results can be used by the BP network to achieve accurate matching. Unlike the conventional k-means and self-organizing feature map (SOFM), VC is a self-creating network; the number of clusters is self-organizing and need not be pre-specified. The BP network, using differential features as input training data, can learn the functional relationship between differential features and the matching degree. After training, the BP network is first used to generate an initial disparity (range) map. With the clustering results and the initial map, a matching algorithm that incorporates the BP network is then applied to recursively refine the map in a cluster-bycluster manner. In the matching process, useful constraints, such as a epipolar line, ordering, geometry and continuity, are employed to reduce the occurrence of mismatching. The matching process continues until all clusters are matched. Empirical results indicate that the proposed framework is very promising for applications in stereo vision.
Three dimensional micromagnetic analysis of write head dynamics and field patterns (2001)

A three-dimensional micromagnetic tip model is utilized to study magnetization switching dynamics and the external head fields of a write head. For a flux rise time of 0.1 ns, the head field follows the input flux up to about 60% of saturation, and slowly approaches saturation. At a flux rise time of 0.5 ns, the head field follows the input flux closely. Calculated head held gradients agree well in the gap region with the theoretical Lindholm model. At the track edge, the perpendicular and crosstrack field components remain fairly constant.
A Novel Low-Density Lipoprotein Receptor-Related Protein with Type II Membrane Protein-Like Structure Is Abundant in Heart (1998)

We report herein the identification of a novel member of the low-density lipoprotein receptor (LDLR) family termed LDLR-related protein 4 (LRP4). Murine LRP4 cDNA encodes a 1113-amino-acid type II membrane-like protein with eight ligand-binding repeats in two clusters. Southern blot analysis of genomic DNA from several different organisms suggests the presence of LRP4 homologues in chicken lacking the gene encoding apolipoprotein E, which is recognized by the ligand-binding repeats of LDLR. LRP4 transcripts were detected almost exclusively in heart in mouse and humans. Despite the presence of the ligand-binding repeats, COS cells transfected with LRP4 did not show surface-binding of beta-migrating very-low-density lipoprotein, suggesting that LRP4 plays a role in a pathway other than lipoprotein metabolism.
Wavelength-selective 1/spl times/K switches using free-space optics and MEMS micromirrors: theory, design, and implementation (2005)

The design and performance of several generations of wavelength-selective 1/spl times/K switches are reviewed. These optical subsystems combine the functionality of a demultiplexer, per-wavelength switch, and multiplexer in a single, low-loss unit. Free-space optics is utilized for spatially separating the constituent wavelength division multiplexing (WDM) channels as well as for space-division switching from an input optical fiber to one of K output fibers (1/spl times/K functionality) on a channel-by-channel basis using a microelectromechanical system (MEMS) micromirror array. The switches are designed to provide wide and flat passbands for minimal signal distortion. They can also provide spectral equalization and channel blocking functionality, making them well suited for use in transparent WDM optical mesh networks.
Static Analysis of Binary Executables Using Structural SVMs (2010)

We cast the problem of identifying basic blocks of code in a binary executable as learning a mapping from a byte sequence to a segmentation of the sequence. In general, inference in segmentation models, such as semi-CRFs, can be cubic in the length of the sequence. By taking advantage of the structure of our problem, we derive a linear-time inference algorithm which makes our approach practical, given that even small programs are tens or hundreds of thousands bytes long. Furthermore, we introduce two loss functions which are appropriate for our problem and show how to use structural SVMs to optimize the learned mapping for these losses. Finally, we present experimental results that demonstrate the advantages of our method against a strong baseline. 1
Synthesis of Crack-Free PZT thin Films by Sol-gel Processing on Glass Substrate (2015)

PZT thin films deposited on glass substrates have been proposed for many applications such as adjustable optics in future X-ray telescopes. Sol-gel method is widely utilized to prepare PZT thin films due to its low reaction temperature, uniform mixing of reactants, and precise control of component. Crack-free transparent PZT thin films were prepared by dip-coating the solutions of complex alkoxides. PZT thin films were calcined at various temperatures and characterized by X-ray diffraction, field emission scanning electron microscopy to examine the surface morphology, and FT-IR spectroscopy. The XRD analysis confirmed the formation of perovskite phase at 600 °C. FE-SEM results showed nucleation of PZT perovskite phase. Furthermore, the average grain size was measured in the range of 55 to 190 nm.
Chemomechanical Gels for Actuator System Controlled by Electrochemical Reaction (1996)

We aim to make an actuator that uses the osmotic pressure of chemomechanical gels and is controlled by electrochemical reaction. This paper presents the preparation of the gels and measurement of pH change and gel actuation by the electrochemical reaction. Finally, we suggest one example of application suitable for gel actuator. The gels are made by photo-polymerization with ultraviolet irradiation to vinyl-monomers which are N,N'-dimethyl aminopropyl acrolamide (DMAPAA), Methylene-bis-acrylamide (MBAAM). Poly-vinyl alcohol (PVA) is added to the monomer solution to make the gels elastic. Swelling ratio and Young's modulus of the gels were measured in electrolyte solution with deferent pH and ion concentration. It became clear that the Young 's modulus of the gels increased with increasing the swelling ratio which was proportional to the osmotic pressure. This result is suitable for the actuator which uses the swelling pressure of the gels. The oxidizing and reducing agent for the electrochemical reaction is Ethyl Viologen Dibromide. The cell with the working electrode is separated from the cell with the counter one by an ion exchange membrane. The oxidation by applied potential of + 1.0 V decreases pH from 12 to 4 within 3 minutes. In the case of reduction, the potential of -0.8 V increases pH for 4 to 12 within the same minutes. The change of pH swells or shrinks the chemomechanical gels similar to adding acid or alkaline to the solution. Without stirring, it is difficult that pH change spreads into the gel completely in the short time, which causes the hysteresis. As the application of the gel actuator, a continuous dispenser is suggested and confirmed to discharge liquid from the balloon.

Enzastaurin (LY317615), a protein kinase Cβ inhibitor, inhibits the AKT pathway and induces apoptosis in multiple myeloma cell lines (2006)

Enzastaurin (LY317615), an acyclic bisindolylmaleimide, is an oral inhibitor of the protein kinase Cbeta isozyme. The objective of this study was to assess the efficacy of enzastaurin in inducing apoptosis in multiple myeloma (MM) cell lines and to investigate possible mechanisms of apoptosis. Cell proliferation assays were done on a variety of MM cell lines with unique characteristics (dexamethasone sensitive, dexamethasone resistant, chemotherapy sensitive, and melphalan resistant). The dexamethasone-sensitive MM.1S cell line was used to further assess the effect of enzastaurin in the presence of dexamethasone, insulin-like growth factor-I (IGF-I), interleukin-6, and the pan-specific caspase inhibitor ZVAD-fmk. Enzastaurin increased cell death in all cell lines at clinically significant low micromolar concentrations (1-3 micromol/L) after 72 hours of treatment. Dexamethasone and enzastaurin were shown to have an additive effect on MM.1S cell death. Although IGF-I blocked the effect of 1 micromol/L enzastaurin, IGF-I did not abrogate cell death induced with 3 mumol/L enzastaurin. Moreover, enzastaurin-induced cell death was not affected by interleukin-6 or ZVAD-fmk. GSK3beta phosphorylation, a reliable pharmacodynamic marker for enzastaurin activity, and AKT phosphorylation were both decreased with enzastaurin treatment. These data indicate that enzastaurin induces apoptosis in MM cell lines in a caspase-independent manner and that enzastaurin exerts its antimyeloma effect by inhibiting signaling through the AKT pathway.

Oncogenomics to Target Myeloma in the Bone Marrow Microenvironment (2011)

Multiple myeloma (MM) is an example of rapid bench-to-bedside translation in new drug development. Bortezomib and lenalidamide target the tumor cell in the bone marrow microenvironment to overcome drug resistance in laboratory and animal models; each is effective to treat relapsed and/or refractory, relapsed, and newly diagnosed MM, and both are now showing promise as maintenance therapy. Major ongoing translational research efforts include improved classification and personalized therapies; identification and validation of next-generation agents targeting the tumor cell in its microenvironment; novel immune therapies; rationally based combination therapies; and use of novel agents to delay or prevent development of active MM. This paradigm of targeting the tumor in its microenvironment has already extended median survival in MM from 3 to 7 to 8 years and has great potential to improve patient outcome in other hematologic malignancies and solid tumors as well.

Segmentation and analysis of the tissue composition of dermatological ulcers (2010)

Ulcered lesions on the legs and feet caused by venous insufficiency and other conditions require long-term clinical treatment and follow-up. To facilitate the analysis of the tissue composition of a lesion, we propose color imaging and image processing methods. Methods considering the bottom tissues are proposed for the segmentation of a given image into regions corresponding to red granulation, yellow fibrin, black scar, and white hyperkeratotic tissue (callous). Tests with 172 images and comparison with visual analysis by a dermatologist indicated an average root-mean-squared error of 22.7% in tissue composition. In retrospective analysis, the dermatologist indicated that the results were accurate for 31.4% and acceptable for 14% of the images. Comparison between the lesion area obtained automatically and the same lesion region manually drawn by a dermatologist indicated an average superposition of 0.61.
