A Fully-Scalable De-Embedding Method for On- Wafer S-Parameter Characterization of CMOS RFMicrowave Devices (2005)

An accurate and efficient de-embedding method for on-wafer device measurements at RFlmicrowave frequencies is presented. This method is based on transmission-line theory and does not require any physical equivalent-circuit model for external parasitic components. The propagation constant and characteristic impedance of the THRU dummy structure were determined to create scalable interconnect parameters for the parasitic networks connected to the three terminals of a MOSFET. Compared with the conventional scalable de-embedding method, the proposed procedure can further eliminate the unwanted parasitics from the source terminal. The performance of this new method was also validated by comparison with the open-s hort de-embedding technique.
Interpolation method in simple computed tomography scanner (2015)

A method for sinogram data interpolation based on a sinusoidal pattern in computed tomography has been developed. Sampled sinograms were acquired based on angular interval scanning of 5<sup>o</sup>, 10<sup>o</sup>, and 20<sup>o</sup>. Then each resulted sinogram was interpolated following sinusoidal pattern to make a complete full scanning sinogram as if they were sampled at 1<sup>o</sup>. After that, a formal summation convolved filtered back projection was applied to each sinogram to yield a crosssectional image. This method was successfully interpolated limited number of projections data to obtained complete sinogram. It works for simple and homogenous object. However, for high variation of physical properties, e.g. linear attenuation coefficient values, this method needs more consideration on interpolation strategies to produce good image.
Sedative, Amnestic, and Analgesic Properties of Small-Dose Dexmedetomidine Infusions (2000)

This research determined the safety and efficacy of two small-dose infusions of dexmedetomidine by evaluating sedation, analgesia, cognition, and cardiorespiratory function. Seven healthy young volunteers provided informed consent and participated on three occasions with random assignment to drug or placebo. Heart rate, blood pressure, respiratory rate, ETCO(2), O(2) saturation, and processed electroencephalogram (bispectral analysis) were monitored. Baseline hemodynamic measurements were acquired, and psychometric tests were performed (visual analog scale for sedation; observer's assessment of alertness/sedation scale; digit symbol substitution test; and memory). The pain from a 1-min cold pressor test was quantified with a visual analog scale. After a 10-min initial dose of saline or 6 microg. kg(-1). h(-1) dexmedetomidine, volunteers received 50-min IV infusions of saline, or 0.2 or 0.6 microg. kg(-1). h(-1) dexmedetomidine. Measurements were repeated at the end of infusion and during recovery. The two dexmedetomidine infusions resulted in similar and significant sedation (30%-60%), impairment of memory (approximately 50%), and psychomotor performance (28%-41%). Hemodynamics, oxygen saturation, ETCO(2), and respiratory rate were well preserved throughout the infusion and recovery periods. Pain to the cold pressor test was reduced by 30% during dexmedetomidine infusion. Small-dose dexmedetomidine provided sedation, analgesia, and memory and cognitive impairment. These properties might prove useful in a postoperative or intensive care unit setting. IMPLICATIPNS: The alpha(2) agonist, dexmedetomidine, has sedation and analgesic properties. This study quantified these effects, as well as cardiorespiratory, memory and psychomotor effects, in healthy volunteers. Dexmedetomidine infusions resulted in reversible sedation, mild analgesia, and memory impairment without cardiorespiratory compromise.
Molecular Classifiers for Gastric Cancer and Nonmalignant Diseases of the Gastric Mucosa (2004)

High incidence of gastric cancer-related death is mainly due to diagnosis at an advanced stage in addition to the lack of adequate neoadjuvant therapy. Hence, new tools aimed at early diagnosis would have a positive impact in the outcome of the disease. Using cDNA arrays having 376 genes either identified previously as altered in gastric tumors or known to be altered in human cancer, we determined expression signature of 99 tissue fragments representing normal gastric mucosa, gastritis, intestinal metaplasia, and adenocarcinomas. We first validated the array by identifying molecular markers that are associated with intestinal metaplasia, considered as a transition stage of gastric adenocarcinomas of the intestinal type as well as markers that are associated with diffuse type of gastric adenocarcinomas. Next, we applied Fisher's linear discriminant analysis in an exhaustive search of trios of genes that could be used to build classifiers for class distinction. Many classifiers could distinguish between normal and tumor samples, whereas, for the distinction of gastritis from tumor and for metaplasia from tumor, fewer classifiers were identified. Statistical validations showed that trios that discriminate between normal and tumor samples are powerful classifiers to distinguish between tumor and nontumor samples. More relevant, it was possible to identify samples of intestinal metaplasia that have expression signature resembling that of an adenocarcinoma and can now be used for follow-up of patients to determine their potential as a prognostic test for malignant transformation.

Laser Sclerostomy by Pulsed-Dye Laser and Goniolens (1990)

We describe an ab-interno laser sclerostomy procedure using the method termed dye-enhanced ablation with a slit-lamp delivery system and special goniolens such that only the laser light beam penetrates the anterior chamber. The procedure uses a microsecond-pulsed-dye laser emitting at 666 nm and iontophoresis of methylene blue dye (absorption of 668 nm) into the sclera at the limbus to enhance the absorption of the laser light. We compared the number of pulses needed to perforate excised human sclera at pulse durations of 1.5, 20, and 300 microseconds. Pulse durations of 1.5 and 20 microseconds required 20 pulses or fewer to perforate excised human sclera with pulse energies of 75 to 100 mJ. The ab-interno laser sclerostomy procedure was performed in 54 eyes of Dutch-belted rabbits with pulse durations of 1.5 or 20 microseconds and a 100- or 200-microns incident spot diameter delivered using a CGF goniolens. Full-thickness fistulas were successfully created at both pulse durations in approximately 80% of eyes treated. A range of three to 25 pulses was required to perforate sclera with slightly fewer pulses and lower pulse energies at 1.5 microseconds compared with 20 microseconds. There were no significant complications from the procedure. This technique could permit filtration surgery to be performed on an outpatient basis.
A Shareable Secure and Privacy Preserving Auditing Scheme for Cloud Storage Security (2016)

Cloud data security has been a concern as the cloud is considered untrusted environment. People across the globe can have cloud storage services in pay per use fashion. In this environment, enterprises store their valuable data in cloud. However, due to security concerns most of the cloud data owners are concerned about the integrity of data that has been outsourced. Many schemes came into existence in order to have integrity of data. Some schemes focused on cryptographic primitives while other schemes focused on provable data possession schemes. In this paper, we proposed and implemented a shareable secure and privacy preserving auditing scheme for cloud storage security. It makes use of mechanisms to recover data if data is corrupted or subjected to illegal tampering. We built a prototype application that shows the proof of concept. The empirical results suggest that the proposed approach is able to protect outsourced data to cloud Cite this Article Raju Dara, Doddikousari Kumari.

Addition of a methyl group changes both the catalytic velocity and thermostability of the neutral protease from <i>Bacillus stearothermophilus</i> (1989)

Specific activity was compared between wild-type (WT) neutral protease from Bacillus stearothermophilus and mutant protease (M1; Gly144 replaced by Ala144) with enhanced thermostability. When casein was used as a substrate, M1 showed 1.5-times higher specific activity than that of WT. In contrast, the specific activities of M1 for soluble reduced lysozyme and insulin B chain were lower than those of WT by 17.2 and 13.2%, respectively. After digestion of the insulin A chain by these enzymes, the peptide products were purified and the N-terminal amino acid sequences were determined. WT enzyme cleaved insulin A chain at three sites, whereas no digestion was observed with M1. Using Z-Gly-Leu-NH2 as a substrate, the kinetic parameters were determined. The Km values are nearly equal for both enzymes, whereas the kcat of M1 (240 min-1) was much smaller compared to the WT (830 min-1). The data indicate that the mutation (addition of a methyl group) exerts an effect by changing both the catalytic velocity and thermostability.
Exploratory Population PK Analysis of Dupilumab, a Fully Human Monoclonal Antibody Against IL‐4Rα, in Atopic Dermatitis Patients and Normal Volunteers (2016)

An exploratory population pharmacokinetic model for functional dupilumab was developed. Data from healthy volunteers and patients with atopic dermatitis (AD) receiving intravenous or subcutaneous doses were integrated. The data included 197 participants (2,518 measurements of dupilumab in serum) from six phase I and II studies. The data were analyzed using stochastic approximation expectation-maximization and importance sampling methods. The best structural model was a two-compartment model with parallel linear and Michaelis-Menten elimination from the central compartment. Estimated parameters were: central volume 2.74 L, elimination rate 0.0459 d<sup>-1</sup> , central-to-peripheral rate 0.0652 d<sup>-1</sup> , peripheral-to-central rate 0.129 d<sup>-1</sup> , bioavailability 60.7%, maximal target-mediated elimination rate 0.968 mg/L/d, and Michaelis-Menten constant 0.01 mg/L. Body weight was a significant covariate of the central volume. No gender effect was observed when controlling for weight. No differences between healthy volunteers and patients with AD were found. The model adequately described dupilumab pharmacokinetics for intravenous and subcutaneous routes of administration.

Rejuvenation of channel electron multipliers (1984)

One of the problems with channel electron multipliers is the gradual degradation in performance with age. A simple process has been developed to restore some of the original performance to aged multipliers and thus to extend their useful lifetime.
Omnidirectional Cameras as Backing-Up Aid (2007)

Omnidirectional cameras are well suited for maneuvering tasks due to to their large field of view. We mounted two catadioptric cameras on a vehicle and provide the driver with a bird's-eye view of the surrounding area behind the vehicle as well as the area on the left and right hand side. In order to enlarge the field of view of the bird's-eye view image, we will show an extension to the bird's-eye view image that provides a larger field of view and thus simplifies challenging maneuvering tasks. An overlay onto the resulting image shows the motion path of the vehicle while reversing. This motion path is connected to the steering angle. The driver can easily see where the vehicle will move when the steering angle is not changed throughout the movement.
A new temporal CSP framework handling composite variables and activity constraints (2005)

A well known approach to managing the numeric and the symbolic aspects of time is to view them as constraint satisfaction problems (CSPs). Our aim is to extend the temporal CSP formalism in order to include activity constraints and composite variables. Indeed, in many real life applications the set of variables involved by the temporal constraint problem to solve is not known in advance. More precisely, while some temporal variables (called events) are available in the initial problem, others are added dynamically to the problem during the resolution process via activity constraints and composite variables. Activity constraints allow some variables to be activated (added to the problem) when activity conditions are true. Composite variables are defined on finite domains of events. We propose in this paper two methods based respectively on constraint propagation and stochastic local search (SLS) for solving temporal constraint problems with activity constraints and composite variables. We call these problems conditional and composite temporal constraint satisfaction problems (CCTCSPs). Experimental study we conducted on randomly generated CCTCSPs demonstrates the efficiency of our exact method based on constraint propagation in the case of middle constrained and over constrained problems while the SLS based method is the technique of choice for under constrained problems and also in case we want to trade search time for the quality of the solution returned (number of solved constraints)
<title>Active browsing using similarity pyramids</title> (1998)

In this paper, we describe a new approach to managing large image databases, which we call active browsing. Active browsing integrates relevance feedback into the browsing environment, so that users can modify the database's organization to suit the desired task. Our method is based on a similarity pyramid data structure, which hierarchically organizes the database, so that it can be efficiently browsed. At coarse levels, the similarity pyramid allows users to view the database as large clusters of similar images. Alternatively, users can 'zoom into' finer levels to view individual images. We discuss relevance feedback for the browsing process, and argue that it is fundamentally different from relevance feedback for more traditional search-by-query tasks. We propose two fundamental operations for active browsing: pruning and reorganization. Both of these operations depend on a user-defined relevance set, which represents the image or set of images desired by the user. We present statistical methods for accurately pruning the database, and we propose a new 'worm hole' distance metric for reorganizing the database, so that members of the relevance set are grouped together.
Controlling Fluorine Concentration and Thermal Annealing Effect on Liquid‐Phase Deposited SiO2 − x  F  x Films (1995)

Silicon oxide with fluorine naturally incorporated can be prepared by the liquid‐phase deposition (LPD) method at 15°C. The fluorine is uniformly distributed in the bulk of the LPD oxide. The fluorine incorporation as well as the qualitative properties can be accurately controlled by varying the amount of added. A high temperature process has considerable effect on the low temperature fluorinated oxide. FTIR and XPS spectra show that Si—F and bonds can restructure with densification at higher thermal annealing temperature, and that restructuring is a function of temperature. Film densification with increasing temperature is also discussed in terms of Si—O—Si bond angle and Si‐Si bond length.
Automatic eye feature extraction in human face images (2001)

This paper presents a fuzzy-based method to extract the eye features in a head-shoulder image with plain background. This method is comprised of two stages, namely the face region estimation and the eye features extraction. In the first stage, a region growing method is adopted to estimate the face region. In the second stage, the coarse eye area is firstly determined based on the location of the nasion, then the deformable template algorithm is completed in two steps to extract the features of the eyes. Experimental results show the efficiency and robustness of this method.
Quantitative analysis of specific mRNA transcripts using a competitive PCR assay with electrochemiluminescent detection. (1995)

Reverse transcriptase-polymerase chain reaction (RT--PCR) has been widely utilized for both the qualitative and quantitative assessment of the levels of specific mRNA transcripts in living systems. Quantitation of specific transcripts has often proved to be problematic because of the difficulty associated with relating the PCR-amplified product to the starting cDNA representing the mRNA of interest. We have overcome these difficulties and have developed a competitive PCR assay employing the property of electrochemiluminescence for the detection of PCR products. This assay possesses the dual advantage of being both nonradioactive and highly sensitive.
Cell Surface Expression of Calnexin, a Molecular Chaperone in the Endoplasmic Reticulum (2000)

The folding and assembly of nascent proteins in the endoplasmic reticulum are assisted by the molecular chaperone calnexin, which is itself retained within the endoplasmic reticulum. It was up to now assumed that calnexin was selectively expressed on the surface of immature thymocytes because of a particular characteristic of the protein sorting machinery in these cells. We now report that a small fraction of calnexin is normally expressed on the surface of various cells such as mastocytoma cells, murine splenocytes, fibroblast cells, and human HeLa cells. Surface biotinylation followed by chase culture of living cells revealed that calnexin is continuously delivered to the cell surface and then internalized for lysosomal degradation. These results suggest that there is continuous exocytosis and endocytosis of calnexin, and the amount of calnexin on the plasma membrane results from the balance of the rates of these two events. To study the structural requirement of calnexin for surface expression, we created deletion mutants of calnexin and found that the luminal domain, particularly the glycoprotein binding domain, is necessary. These findings suggest that the surface expression of calnexin depends on the association with glycoproteins and that calnexin may play a certain role as a chaperone on the plasma membrane as well.
The electrical properties and retention characteristics of strained PZT thin film capacitors (2001)

Abstract We have investigated the effect of externally controlled bi-axial stress on the electrical properties and retention characteristics of Pb(Zr0.52,Ti0.48)O3 (PZT) thin films. The PZT thin films exhibited a low residual tensile stress, i.e. 120 MPa. Under external compressive stress, the switching polarization or remanent polarization increased with the compressive stress. Coercive field also increased with the compressive stress. Upon applying a biaxial stress of 240 MPa, the switching polarization increased to 40 μC/cm2 while the PZT films with the residual tensile stress had 31 μC/cm2. On the other hand, PZT thin films under the tensile stress exhibited slightly decreasing switching polarization and the coercive field with increasing the tensile stress. Retention test revealed that both the external bi-axial stressed and unstressed PZT thin films showed the same polarization decay behavior (15% loss) within 1 second, whereas the mechanically stressed PZT thin films showed more suppressed polarization decay than unstressed one for a long period of retention time.

Application of a Bank of Kalman Filters for Aircraft Engine Fault Diagnostics (2003)

In this paper, a bank of Kalman filters is applied to aircraft gas turbine engine sensor and actuator fault detection and isolation (FDI) in conjunction with the detection of component faults. This approach uses multiple Kalman filters, each of which is designed for detecting a specific sensor or actuator fault. In the event that a fault does occur, all filters except the one using the correct hypothesis will produce large estimation errors, thereby isolating the specific fault. In the meantime, a set of parameters that indicate engine component performance is estimated for the detection of abrupt degradation. The proposed FDI approach is applied to a nonlinear engine simulation at nominal and aged conditions, and the evaluation results for various engine faults at cruise operating conditions are given. The ability of the proposed approach to reliably detect and isolate sensor and actuator faults is demonstrated.
Common features of the reservoir-associated seismic activities (1972)

abstract A detailed examination of the behavior of earthquakes associated with over a dozen artificial lakes shows that, in all cases, the tremors were initiated or their frequency increased considerably following the lake filling and that their epicenters were mostly located within a distance of 25 km from the lakes. Among the factors affecting the tremor frequency are the rate of increase of water level, duration of loading, maximum levels reached, and the period for which the high levels are retained. The study of these reservoir-associated earthquake sequences reveals that the ratio of the largest aftershock to the main shock is high (about 0.9), and the b values are also high in the frequency-magnitude relation, which is contrary to the normal earthquakes of the concerned regions.
