A DRM System Protecting Consumer Privacy (2008)

Digital rights management (DRM) is widely used to protect intellectual property for content owners but consumer privacy is sacrificed. A user's playing statistics can be collected by the client DRM module and the license server. In this paper, we propose a DRM system in which the license server can generate the content decryption key for a user to play an encrypted content object without gaining any information to link to the specific content object encrypted by the content encryption key. This is achieved by applying a (partially) blind signature primitive in the license acquisition protocol and by adopting a key scheme that a content encryption key depends on the information retrieved from the content object and a secret that only the license server knows. By requesting that the client DRM module does not send any information about a user's playing statistics and all the messages the client DRM module sends out are in plain text for easy checking by a user if the client DRM module abides by this rule, consumer privacy is fully protected in our DRM system.
Protection of immunosuppressed mice against infection with Pseudomonas aeruginosa by recombinant P. aeruginosa lipoprotein I and lipoprotein I-specific monoclonal antibodies (1991)

Outer membrane protein I (OprI) is one of the major proteins of the outer membrane of Pseudomonas aeruginosa. The protective effect of OprI vaccination and that of three OprI-specific monoclonal antibodies (MAbs) against infection with P. aeruginosa were tested in immunosuppressed mice. The combination of Oprl and MAb 2A1 protected the mice against a challenge with a 96-fold 50% lethal dose. The binding site of MAb 2A1 was mapped, resulting in the identification of a protective epitope (amino acids 7 to 20).
A 7-bit 300-MS/s subranging ADC with embedded threshold &amp; gain-loss calibration (2011)

This paper reports a 7-bit 300-MS/s subranging ADC fabricated in standard 65nm CMOS, which utilizes embedded reference and gain loss error calibration techniques. A shared passive capacitive DAC array performs the input sampling in quantization mode and reference generation in calibration mode, providing a linear, accurate and compact calibration implementation. As a consequence of the developed calibration techniques, uniform-sized dynamic comparators are employed to reduce the process-mismatch variation and nonlinearity error, when compared with the conventional structures. The ADC achieves peak SNDR of 40.5dB at 300MS/s and 39dB at 400MS/s, with ERBW of 300MHz and 350MHz, respectively. The power consumption is 2.3mW only from 1.2-V supply at 300MS/s.
The Rb family of cell cycle regulatory factors: clinical implications. (2000)

The retinoblastoma gene family is composed of three members: the product of the retinoblastoma gene (pRb), which is one of the most well studied tumor suppressor genes and two related proteins, pRb2/p130 and p107, which have been shown to be structurally and functionally similar to pRb. The three retinoblastoma family members show growth suppressive properties, although the growth arrest mediated by each of the three pocket regions of the proteins is not identical. This supports the idea that although the three members may complement each other, they are not fully functional or redundant. Among the three family members, the retinoblastoma-related gene product pRb2/p130 is a tumor suppressor gene and an effective candidate target for gene therapy approach. The aim of this review is to examine the role of the Rb family members in growth regulation discussing their putative prognostic and therapeutical impact in human cancer.
Enhancement method that provides direct and independent control of fundamental attributes of image quality for radiographic imagery (2004)

Image processing is used to transform raw digital radiographic image data, captured using CR (computed radiography) and DR (flat panel direct digital radiography) systems into a display-ready form. Ideally, an image-processing algorithm automatically renders an image for display, based on aims derived from observer performance studies. Establishing the rendering aim for different exam types, however, can be complex because the effects on image appearance introduced by the various steps in the rendering process are interdependent. This paper describes a new rendering algorithm that provides orthogonal control, to the first order, of five fundamental attributes of perceived image quality. These attributes are brightness, latitude, detail contrast, sharpness, and appearance of noise. The detail contrast and sharpness can be controlled in a density-dependent manner. The algorithm uses a multifrequency-band decomposition wherein the bands of the decomposition are manipulated, and the reconstructed image is passed through a tone-scale process that prepares the image for display. The rendering method is implemented in software on a workstation that enables interactive control of these image quality attributes in order to facilitate the determination of rendering aims for different exam types.
Joint Learning of Geometric and Probabilistic Constellation Shaping (2019)

The choice of constellations largely affects the performance of communication systems. When designing constellations, both the locations and probability of occurrence of the points can be optimized. These approaches are referred to as geometric and probabilistic shaping, respectively. Usually, the geometry of the constellation is fixed, e.g., quadrature amplitude modulation (QAM) is used. In such cases, the achievable information rate can still be improved by probabilistic shaping. In this work, we show how autoencoders can be leveraged to perform probabilistic shaping of constellations. We devise an information theoretical description of autoencoders, which allows learning of capacity-achieving symbol distributions and constellations. Recently, machine learning techniques to perform geometric shaping were proposed. However, probabilistic shaping is more challenging as it requires the optimization of discrete distributions. Furthermore, the proposed method enables joint probabilistic and geometric shaping of constellations over any channel model. Simulation results show that the learned constellations achieve information rates very close to capacity on an additive white Gaussian noise (AWGN) channel and outperform existing approaches on both AWGN and fading channels.
Admission and bandwidth allocation for soft-QoS guarantees in mobile multimedia networks (2003)

We describe a mobile call admission control algorithm (M-CAC) for mobile multimedia terminals roaming within coverage areas consisting of multiple microcells. The method targets consistent soft-QoS for admitted connections with high utilization of radio resources, exploiting both temporal and spatial statistical multiplexing. We compare the performance of M-CAC to the performance of the default algorithm (all calls are accepted, provided there is enough bandwidth in the originating microcell). Results of our simulations demonstrate that a reasonably good connection-level soft-QoS can be achieved with moderate increase of cost of connections (determined by efficiency of bandwidth utilization).
Identification and real-time expression analysis of selected Toxoplasma gondii in-vivoinduced antigens recognized by IgG and IgM in sera of acute toxoplasmosis patients (2013)

The highly up-regulated genes and the corresponding proteins, in particular the hypothetical proteins, may be useful in further studies on understanding the disease pathogenesis and as potential vaccine candidates.
Acoustical Detection Of Flameout In A Combustor (1993)

Acoustic flameout detector contains relatively simple decision circuits, because only decision it makes is whether acoustic wave in specific frequency band strong enough. If not, flameout about to occur, and acoustic flameout detector sends signal to turn off supply of fuel.
Practical tracing traitors (2009)

In this paper we discuss tracing traitors systems, with a focus on a particular problem we have encountered in building a commercial system. "Tracing traitors" is a cryptographic technology that determines, when an unauthorized copy of copyrighted content is encountered, which user or users were the source of the copy by examining the copy itself. In tracing traitors systems, it has been widely assumed that any two devices in the system should have as few cryptographic keys in common as possible: then, when the variation the key decrypts is discovered in the unauthorized copy, the number of devices that could have produced that variation is minimal. This assumption is so pervasive it often is not even stated explicitly. However, tracing traitors schemes also often ignore the likely next step-once the compromised device(s) are identified, their keys must be revoked so they cannot be further used in the system. In this paper we will show that the traceability of any minimal-key-overlap system inevitably begins to degrade once some of the keys are revoked. This has caused us to question the basic value of minimal key overlap. In fact, we think that very revocation-efficient key schemes, like broadcast-encryption key trees, in which some keys are highly shared, might actually provide better traceability over the life of a practical system with actual revocation.
Refined processing and forestry management guarantee sustainability and ecological benefits (2011)

Used for washing since ancient times the extract of the saponin rich bark of the Chilean Soapbark tree Quillaja saponaria was exported since 1880 to fulfil the fast growing demand for Quillaja as a foaming agent, emulsifier, and detergent for a multitude of industrial purposes. Traditionally only the bark was extracted and the wood of the felled tree, equalling 95 percent of the biomass, was left to rot. To stop the wastage and the damage to environment, Natural Response, the Catholic University of Chile and Desert King International developed a new process strategy for saponin extraction of the entire wood. New sustainable harvesting regimes, the increasing plantations and reforestation policies guarantee future bioavailability and benefit the environment and the peasant population as well. Quillaja saponaria wood extract
Laser-Diode Based Scanning Force Microscope and Ultrafast Sampling Probe (1995)

New discoveries in fabrication technology and in device physics have open the way for a class of electronic and optoelectronic devices with nanometer-scale dimensions. These devices offer the opportunity to work with electrons confined to 2-D, 1-D and 0-D in space. In an effort to understand how individual devices work it will be necessary to interrogate individual submicron structures . Aside from the fine dimensions of the contacts used for such measurements it will be necessary to make measurement with very low invasiveness and increasingly, with higher speed. To meet the challenges of new nano-technologies we have developed a probe which demonstrates high impedance voltage measurement using a 0.1-micron contacting tip. The voltage of the tip is photoconductively sampled allowing waveforms to be measured with picosecond resolution [l]. In this paper we describe the operation of the probe using a gain switched laser diode to make measurements which extract only a few fC from the device under test. We also show the probes value as a high-speed, high sensitivity probe for millimeter-wave circuits.

Smooth Nanowire/Polymer Composite Transparent Electrodes (2011)

Smooth composite transparent electrodes are fabricated via lamination of silver nanowires into the polymer poly-(4,3-ethylene dioxythiophene):poly(styrene-sulfonate) (PEDOT:PSS). The surface roughness is dramatically reduced compared to bare nanowires. High-efficiency P3HT:PCBM organic photovoltaic cells can be fabricated using these composites, reproducing the performance of cells on indium tin oxide (ITO) on glass and improving the performance of cells on ITO on plastic.
Model-based reconstruction of objects with inexactly known components (2012)

Because tomographic reconstructions are ill-conditioned, algorithms that incorporate additional knowledge about the imaging volume generally have improved image quality. This is particularly true when measurements are noisy or have missing data. This paper presents a general reconstruction framework for including attenuation contributions from objects known to be in the field-of-view. Components such as surgical devices and tools may be modeled explicitly as part of the attenuating volume but are <i>inexactly</i> known with respect to their locations poses, and possible deformations. The proposed reconstruction framework, referred to as Known-Component Reconstruction (KCR), is based on this novel parameterization of the object, a likelihood-based objective function, and alternating optimizations between registration and image parameters to jointly estimate the both the underlying attenuation and unknown registrations. A deformable KCR (dKCR) approach is introduced that adopts a control point-based warping operator to accommodate shape mismatches between the component model and the physical component, thereby allowing for a more general class of inexactly known components. The KCR and dKCR approaches are applied to low-dose cone-beam CT data with spine fixation hardware present in the imaging volume. Such data is particularly challenging due to photon starvation effects in projection data behind the metallic components. The proposed algorithms are compared with traditional filtered-backprojection and penalized-likelihood reconstructions and found to provide substantially improved image quality. Whereas traditional approaches exhibit significant artifacts that complicate detection of breaches or fractures near metal, the KCR framework tends to provide good visualization of anatomy right up to the boundary of surgical devices.
Fecal Bacteria Act as Novel Biomarkers for Noninvasive Diagnosis of Colorectal Cancer (2016)

<b>Purpose:</b> Gut microbiota have been implicated in the development of colorectal cancer. We evaluated the utility of fecal bacterial marker candidates identified by our metagenome sequencing analysis for colorectal cancer diagnosis.<b>Experimental Design:</b> Subjects (total 439; 203 colorectal cancer and 236 healthy subjects) from two independent Asian cohorts were included. Probe-based duplex quantitative PCR (qPCR) assays were established for the quantification of bacterial marker candidates.<b>Results:</b> Candidates identified by metagenome sequencing, including <i>Fusobacterium nucleatum</i> (<i>Fn</i>), <i>Bacteroides clarus</i> (<i>Bc</i>), <i>Roseburia intestinalis</i> (<i>Ri</i>), <i>Clostridium hathewayi</i> (<i>Ch</i>), and one undefined species (labeled as <i>m7</i>), were examined in fecal samples of 203 colorectal cancer patients and 236 healthy controls by duplex-qPCR. Strong positive correlations were demonstrated between the quantification of each candidate by our qPCR assays and metagenomics approach (<i>r</i> = 0.801-0.934, all <i>P</i> < 0.0001). <i>Fn</i> was significantly more abundant in colorectal cancer than controls (<i>P</i> < 0.0001), with AUROC of 0.868 (<i>P</i> < 0.0001). At the best cut-off value maximizing sum of sensitivity and specificity, <i>Fn</i> discriminated colorectal cancer from controls with a sensitivity of 77.7%, and specificity of 79.5% in cohort I. A simple linear combination of four bacteria (<i>Fn</i> + <i>Ch</i> + <i>m7</i>-<i>Bc</i>) showed an improved diagnostic ability compared with <i>Fn</i> alone (AUROC = 0.886, <i>P</i> < 0.0001) in cohort I. These findings were further confirmed in an independent cohort II. In particular, improved diagnostic performances of <i>Fn</i> alone (sensitivity 92.8%, specificity 79.8%) and four bacteria (sensitivity 92.8%, specificity 81.5%) were achieved in combination with fecal immunochemical testing for the detection of colorectal cancer.<b>Conclusions:</b> Stool-based colorectal cancer-associated bacteria can serve as novel noninvasive diagnostic biomarkers for colorectal cancer. <i>Clin Cancer Res; 23(8); 2061-70. ©2016 AACR</i>.
Contributions of machine learning to quantitative and real-time mud gas data analysis: A critical review (2022)

The current utility of mud gas data is typically limited to geological and petrophysical correlation, formation evaluation, and fluid typing. A critical and comprehensive review of the literature on mud gas data revealed that the mud gas data is abundantly acquired during drilling but not sufficiently utilized in real time. There is the need to leverage the current advances in machine learning technology and the race towards the digital transformation of the petroleum industry to create new opportunities for more extensive utility of mud gas data. Now that data is the new “oil” or “gold”, the utility of the rich and abundant mud gas data could be explored for real-time applications. Such new possibilities are capable of adding more value to the reservoir characterization workflow ahead of geophysical logging, geological core data analysis, and well testing. Achieving this will facilitate early decision-making, improve safety, reduce nonproductive time, and ultimately accelerate the attainment of the digital transformation objective of the petroleum industry. We conclude with identifying possible future directions for the ultimate attainment of maximizing the utility of mud gas data through real-time and more advanced applications.
S1P–S1PR2 Axis Mediates Homing of Muse Cells Into Damaged Heart for Long-Lasting Tissue Repair and Functional Recovery After Acute Myocardial Infarction (2018)

Muse cells may provide reparative effects and robust functional recovery and may, thus, provide a novel strategy for the treatment of acute myocardial infarction.
Model-based respiratory motion compensation for image-guided cardiac interventions (2010)

In this paper we propose and validate a PCA-based respiratory motion model for motion compensation during image-guided cardiac interventions. In a preparatory training phase, a preoperative 3-D segmentation of the coronary arteries is automatically registered with a cardiac gated biplane cineangiogram, and used to build a respiratory motion model. This motion model is subsequently used as a prior within the intraoperative registration process for motion compensation to restrict the search space. Our hypothesis is that the use of this model-constrained registration increases the robustness and registration accuracy, especially for weak data constraints such as low signal-to-noise ratio, the lack of contrast information, or an intraoperative monoplane setting. This allows for reducing radiation exposure without compromising on registration accuracy. Synthetic data as well as phantom and clinical datasets have been used to validate the model-based registration in terms of registration accuracy, robustness and speed. We were able to significantly accelerate the intraoperative registration with a 3-D TRE of less than 2 mm for both monoplane images and intraprocedure settings with missing contrast information based on 2-D guidewire tracking, which makes it feasible for motion correction in clinical procedures.
Polymer cholesteric liquid-crystal flake reorientation in an alternating-current electric field (2005)

The motion of highly dielectric polymer cholesteric liquid crystal (PCLC) flakes suspended in a host fluid can be controlled with an ac electric field. The electric field acts to induce a dipole moment on the flake due to interfacial, or Maxwell–Wagner, polarization. Theoretical modeling of PCLC flakes as oblate spheroids shows that the flakes will reorient to align one of the two major axes parallel to the electric field. The theory also supports the observed dependence of the particle reorientation time on the electric-field magnitude, frequency, and particle shape. A PCLC flake’s orientation determines its ability to reflect light of a specific wavelength and circular polarization. The ability to switch the position of PCLC flakes with an electric field has implications for electro-optic devices and display applications.
Tyrosine Kinase Inhibitors. 15. 4-(Phenylamino)quinazoline and 4-(Phenylamino)pyrido[<i>d</i>]pyrimidine Acrylamides as Irreversible Inhibitors of the ATP Binding Site of the Epidermal Growth Factor Receptor (1999)

A series of 6- and 7-acrylamide derivatives of the 4-(phenylamino)quinazoline and -pyridopyrimidine classes of epidermal growth factor receptor (EGFR) inhibitors were prepared from the corresponding amino compounds by reaction with either acryloyl chloride/base or acrylic acid/1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride. All of the 6-acrylamides, but only the parent quinazoline 7-acrylamide, were irreversible inhibitors of the isolated enzyme, confirming that the former are better-positioned, when bound to the enzyme, to react with the critical cysteine-773. Quinazoline, pyrido[3,4-d]pyrimidine, and pyrido[3,2-d]pyrimidine 6-acrylamides were all irreversible inhibitors and showed similar high potencies in the enzyme assay (likely due to titration of the available enzyme). However the pyrido[3,2-d]pyrimidine analogues were 2-6-fold less potent than the others in a cellular autophosphorylation assay for EGFR in A431 cells. The quinazolines were generally less potent overall toward inhibition of heregulin-stimulated autophosphorylation of erbB2 (in MDA-MB-453-cells), whereas the pyridopyrimidines were equipotent. Selected compounds were evaluated in A431 epidermoid and H125 non-small-cell lung cancer human tumor xenografts. The compounds showed better activity when given orally than intraperitoneally. All showed significant tumor growth inhibition (stasis) over a dose range. The poor aqueous solubility of the compounds was a drawback, requiring formulation as fine particulate emulsions.
