All-optical phase regeneration of multi-level amplitude and phase shift keyed signals (2013)

All-optical phase regeneration of multi-level phase shift keyed signals in fiber optic communications systems reduces the impact of phase noise induced by, e.g., self/cross-phase modulation of amplitude varying symbols, and has been previously simulated and experimentally demonstrated [1-3]. Phase regeneration is achieved through a judicious coherent addition of phase harmonics, bearing integer multiples of the signal phase, to the signal via four-wave mixing in a highly nonlinear fiber (HNLF), such that a staircase is realised in the signal phase transfer function of the HNLF. Phase regeneration may allow for greater transmission capacity and optical regeneration has the potential to work faster and consume less power than electronic compensation.
A data mining framework for building intrusion detection models (2003)

There is often the need to update an installed intrusion detection system (IDS) due to new attack methods or upgraded computing environments. Since many current IDSs are constructed by manual encoding of expert knowledge, changes to IDSs are expensive and slow. We describe a data mining framework for adaptively building Intrusion Detection (ID) models. The central idea is to utilize auditing programs to extract an extensive set of features that describe each network connection or host session, and apply data mining programs to learn rules that accurately capture the behavior of intrusions and normal activities. These rules can then be used for misuse detection and anomaly detection. New detection models are incorporated into an existing IDS through a meta-learning (or co-operative learning) process, which produces a meta detection model that combines evidence from multiple models. We discuss the strengths of our data mining programs, namely, classification, meta-learning, association rules, and frequent episodes. We report on the results of applying these programs to the extensively gathered network audit data for the 1998 DARPA Intrusion Detection Evaluation Program.
A pilot study of recombinant interferon beta‐1a for the treatment of chronic hepatitis C (2000)

The results of this pilot study indicate that interferon beta-la administered subcutaneously is an effective therapy for some patients with chronic hepatitis C, and suggest that interferon beta-1a deserves further evaluations in larger trials especially in combination with ribavirin.
Probabilistic High-Cycle Fatigue Risk Assessment of an Integrally Bladed Rotor (2011)

A fully probabilistic high-cycle fatigue (HCF) risk assessment methodology for application to turbine engine blades is described. The assessment uses the Bayesian paradigm of probability theory in which probability distributions are used to encode states of knowledge. Multi-level (or hierarchical) models are employed to capture engineering knowledge of the factors important for assessing HCF risk. This structure allows us to use standard probability distributions to adequately represent uncertainties in model parameters. The model accounts for engine-to-engine, run-to-run, and blade-to-blade variability as well as uncertainty in material capability, usage (flight conditions, time at resonance), and steady and vibratory stresses. Markov chain Monte Carlo (MCMC) simulation is used to fit observed data to the engineering models, then direct Monte Carlo simulation is used to assess the HCF risk.
Adaptive resonance compensation for hard disk drive servo systems (2007)

An add-on compensator is designed to adapt, in a stable, robust, and direct manner, to uncertainty in the resonance characteristics of hard disk drives (HDDs). The design and analysis is based on the linear discretized plant comprising a parallel structure of known nominal voice coil motor (VCM) dynamics and uncertain resonance dynamics. The add-on compensator complements any pre-designed stable nominal control. To prevent the nominal control from being canceled out in adaptive control design, we utilize, as adaptation signal, the error between the output and the auxiliary output, a computable quantity exploiting knowledge of the nominal plant and pre-designed nominal control. Extensive simulation results on a model of the Hitachi 1.8-inch HDD demonstrate the effectiveness of the proposed adaptive compensator in attenuating resonance peaking.
Modulation of voltage‐gated potassium channels by sodium channel SCN1b subunits (2012)

Although voltage‐gated Nav1 sodium channels and Kv1 potassium channels are both known for their tandem function in action potential firing and have ubiquitous tissue expressions, to date, no functional association between members of the Nav1.x channel family and the Kv1 channel family have been reported. Here we report that SCN1b modulates the Kv1‐subfamily of K + channels, each in a unique fashion, when co‐expressed in Xenopus oocytes or mammalian cells (Table). Biochemical experiments show that SCN1b is physically coupled to Kv1 channels. Using chimeras of SCN1b and the myelin Po protein, we demonstrate that the external domain of SCN1b is essential for channel modulation. Two known epilepsy‐causing mutations in the Ig‐domain of SCN1b, R85C and C121W, disrupt Kv1 channel‐modulation. Thus, sodium channel beta subunits may regulate action potential firing and propagation in normal and diseased conditions by modulating the function of both Nav and Kv channels.
Syntheses, Properties, and X-ray Crystal Structures of Piano-Stool Iron Complexes Bearing an N-Heterocyclic Carbene Ligand (2003)

Piano-stool iron complexes containing the C−C unsaturated IMes or saturated H2-IMes ligand are readily synthesized from [CpFe(CO)2(I)]. Substitution of the iodide ligand affords the cationic species [CpFe(CO)2(L)][[I] (1a+I-) and (1b+I-) (a, L = IMes, b, L = H2-IMes), subsequent decarbonylation of which yields the neutral iodo derivatives 2a,b. Cyclic voltammetry studies of 2a,b show a reversible one-electron oxidation to the corresponding 17-electron radical cation. The mono(acetonitrile) complexes 3a,b are obtained from UV irradiation of 1a,b+PF6- in CH3CN, but displacement of the second CO ligand is inhibited by strong metal−CO π-back-donation.
Survival From In-Hospital Cardiac Arrest With Interposed Abdominal Counterpulsation During Cardiopulmonary Resuscitation (1992)

--We conclude that the addition of IAC to standard CPR may improve meaningful survival following in-hospital cardiac arrest. The optimal use of this technique awaits further clinical trials.
A Fair Transaction Model in Mobile Commerce (2006)

Mobile communications offer a wide variety of services to people. All mobile subscribers can use a personal trusted device (PTD) to access various resources and conduct their business anytime from anywhere. This feature has contributed greatly to the rapid development of mobile commerce. In fact, the PTD lack of computing resources has become a problem in mobile commerce development. In this paper, we overcome the limited computation power of PTDs and involve a trusted observer to coordinate transactions such that the important computation requirements can still be accomplished. We integrate some cryptology (such as a digital signature, one-way hash function etc.) and propose a mobile commerce protocol based on PTDs that satisfies the security requirements. These requirements include fairness, non-repudiation, anonymity, simplicity, practicality and so on. We propose a simple and reliable mobile transaction protocol that is independent of specific payment system
Vascular access in Cystic Fibrosis - Does Size Matter? (2005)

Leaderflex lines offer a well-tolerated alternative to standard long lines for the administration of a 14-day course of intravenous antibiotics. Their reduced size and cost offer advantages to patients and doctors.
Synthesis, inhibition of NO production and antiproliferative activities of some indole derivatives (2009)

The synthesis and the biological evaluation of pyrano[3,2-e]indoles and their reaction intermediates are described. The compounds prepared were evaluated for their inhibition of NO production, antioxidant activity and also for their ability to inhibit in vitro the growth of four human tumor cell lines: large lung carcinoma (COR-L23), alveolar basal epithelial carcinoma (A549), amelanotic melanoma (C32) and melanoma (A375). The two reaction intermediates, 5a and 5b, showed the highest inhibition of NO production in murine monocytic macrophage (IC(50) = 1.1 microM and IC(50) = 2.3 microM respectively). Compound 5a was the most active against melanotic melanoma (IC(50) = 11.8 microM) while the other compounds exhibited weak cytotoxicity with IC(50) values >50 microM on all cell lines.
Polyimides Containing Trans-1,4-cyclohexane Unit (II). Low-K and Low-CTE Semi- and Wholly Cycloaliphatic Polyimides (2007)

Polyimide precursors were successfully polymerized from trans-1,4-cyclohexanediamine (CHDA) with pyromellitic dianhydride (PMDA) and 1,2,3,4-cyclobutanetetracarboxylic dianhydride (CBDA) under very limited conditions: at controlled extents of silylation for CHDA in a mixed solvent containing hexamethylphosphoramide (HMPA). Flexible and transparent polyimide films were obtained upon thermal imidization of the precursor films on a substrate after residual solvent extraction from the precursor films by using adequate alcohols. Semi-aromatic PMDA/CHDA polyimide film displayed a considerably lower linear coefficient of thermal expansion (CTE = 9.6 ppm K —1 ) and a relatively low dielectric constant (2.92). On the other hand, wholly cycloaliphatic CBDA/CHDA film attained a low CTE (26 ppm K —1 ) and a considerably lower dielectric constant (2.66), simultaneously. Factors influencing the imidization-induced in-plane orientation, namely, effect of the steric structures of cycloaliphatic units are discussed in comparison with polyimides from hydrogenated PMDA (1,2,4,5-cyclohexanetetracarboxylic dianhydride).
Dynamic Properties of the Two-Dimensional Wigner Solid on the Surface of Normal and Superfluid3He (1997)

We present the theory of transport properties and vibration modes of the two-dimensional Wigner solid (WS) coupled to surface dimples on normal and superfluid 3 He. Compared to the case of liquid 4 He, Fermi liquid properties of the substrate crucially affect the low-frequency dynamics of the electron solid. At ultralow temperatures, WS transport is shown to be determined mostly by the reflection of ballistic quasiparticles of the bulk liquid at the dimple sublattice. The long mean free path regime of normal 3 He is characterized by the temperature-independent conductivity. Below the superfluid transition, the appearance of the quasiparticle energy gap sharply reduces the momentum adsorbed by moving dimples, which leads to the rapid increase of the WS conductivity. The analysis presented shows that the WS can serve as a new powerful experimental probe for superfluid phases of 3 He.
Colony revival, and notes on rearing and life history of the big-headed ant. (1985)

In the laboratory, a queen of the big-headed ant, Pheidole megacephala (Fabr.), could successfully revive an experimental nest with only ten newly eclosed minor workers from the non-feeding pupae. However, a nest that bad no queen, or had a queen with only major workers, with larvae, or with 10 minor workers failed to revive. Queens and major workers from established colonies could not nurse the newly hatched larvae. Detailed information is given on ant collecting and rearing of laboratory stock cultures. A generation of minor workers took 34 to 38 days to complete its life cycle at 26° to 27°C.
A Novel Method of Spatial Calibration for Camera and 2D Radar Based on Registration (2017)

The fusion of sensor data is important to improve the accuracy of vehicle detection in traffic surveillance system. For the sensor fusion, spatial calibration is required between each coordinate system of sensor. In this paper, we propose a new method of spatial calibration between mono camera and 2D radar. Using an AR-marker, which is designed to be detectable by radar, we simultaneously measure the position of marker with respect to the coordinate system of camera and radar. Based on multiple measurements of marker position, the position data is obtained from it. By applying the paired point registration, the transformation is acquired between the coordinate system of radar and camera. The experimental results confirm that the proposed method shows around 0.3 m registration error, which is acceptable for detecting vehicles. We believe that our method can be helpful to enhance the accuracy of vehicle detection in traffic surveillance system and other application such as autonomous driving vehicle.
Efficient time-slot assignment algorithms for SS/TDMA systems with variable-bandwidth beams (1994)

In this paper, we present efficient sequential and parallel algorithms for computation of time-slot assignments in SS/TDMA (satellite-switched/time-division multiple-access) systems with variable-bandwidth beams. These algorithms are based on modeling the time-slot assignment (TSA) problem as a network-flow problem. Our sequential algorithm, in general, has a better time-complexity than a previous algorithm due to Gopal, et al. (1982) and generates fewer switching matrices. If M (N) is the number of uplink (downlink) beams, L is the length of any optimal TSA, and /spl alpha/ is the maximum bandwidth of an uplink or downlink beam, our sequential algorithm takes O((M+N)/sup 3/min(MN/spl alpha/,L)) time to compute an optimal TSA when the traffic-handling capacity of the satellite is of the same order as the total bandwidth of the links. Our parallel algorithm uses L/2 processors and has a time-complexity of O((M+N)/sup 3/logL) on a PRAM model of parallel computation. We then generalize this algorithm to P/spl les/L/2 processors and describe an efficient implementation of the algorithm on a hypercube multiprocessor with P processors. A massively-parallel version of the algorithm runs in O((M+N)/sup 2/log(M+N)logL) time on (M+N)L/2 processors.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
A review of particle transport and separation by electrostatic traveling wave methods (2022)

The controlled movement of dry particles using non-mechanical means is desirable in a number of different applications, including solar panel dust mitigation, toner particle motion and in the handling and beneficiation of regolith for In-Situ Resource Utilization (ISRU). The electric curtain, the electrostatic traveling wave (ETW) and the electro-dynamic screen (EDS) are examples of techniques that can transport and separate particles with no moving parts nor fluid medium. This review paper brings together the research carried out on these techniques. We provide a comprehensive review on the particle movement mechanisms and the development and application of ETW methods, featuring a diverse range of hardware and circuitry, particulate material and process objectives. We focus on the evaluation of experimental development in the area of dust mitigation, particle transport and ISRU processes. We also detail the current knowledge about theory and modelling methods. Moreover, we provide a guide for possible improvement of the effectiveness of ETW devices, by outlining the limitations in application, theoretical understanding and potential research aspects.

Shallow parsing using specialized hmms (2002)

We present a unified technique to solve di#erent shallow parsing tasks as a tagging problem using a Hidden Markov Model-based approach (HMM). This technique consists of the incorporation of the relevant information for each task into the models. To do this, the training corpus is transformed to take into account this information. In this way, no change is necessary for either the training or tagging process, so it allows for the use of a standard HMM approach. Taking into account this information, we construct a Specialized HMM which gives more complete contextual models. We have tested our system on chunking and clause identification tasks using di#erent specialization criteria. The results obtained are in line with the results reported for most of the relevant state-of-the-art approaches.
Laparoscopic, Ultrasound-Guided Microwave Thermal Ablation with Direct, Real- Time Temperature Monitoring of a 3.4 cm Renal Tumor in an Anti-Coagulated Patient (2010)

Purpose: We report the first case of a laparoscopic, ultrasound-guided microwave ablation (MWA) of a renal tumor. The case was performed in a 79 year old female with atrial fibrillation requiring anti-coagulation with successful core biopsy being performed at the same time as the ablation. Methods: A 3.4 cm right lower pole enhancing renal mass was exposed laparoscopically. A microwave ablation probe (3.7 cm active tip, Valley Lab) was positioned under direct vision and laparoscopic ultrasound guidance. Independent fiberoptic, non-conducting temperature sensors (Lumasense, CA) were placed at the deep and peripheral margins of the tumor. Core biopsies of the tumor were performed prior to beginning the ablation. The ablation was continued until all temperature sensors reached greater than 60 degrees Celsius. Results: The patient’s surgery was performed using Lovenox-bridging with reinstitution of coumadin within 24 hours. There was minimal blood loss (less than 20 mol). The preoperative hematocrit was 45.8% and postoperatively 44.8%. Operative time was 56 min, of which the ablation time consisted of 10 min. There were no preoperative or postoperative complications. Follow-up CT scan of the abdomen at six weeks with and without contrast showed no post-operative hematoma and no residual enhancement. Conclusions: MWA is a safe, effective means of thermal ablation of renal tumors. Excellent hemostasis is achieved without the need for hilar dissection and clamping. Tissue ablation is effected via coagulative necrosis and the technique has been applied successfully in an anti-coagulated patient for a mesophytic tumor greater than 3 cm.
Fibroblast growth factor 10 alters the balance between goblet and Paneth cells in the adult mouse small intestine (2015)

Intestinal epithelial cell renewal relies on the right balance of epithelial cell migration, proliferation, differentiation, and apoptosis. Intestinal epithelial cells consist of absorptive and secretory lineage. The latter is comprised of goblet, Paneth, and enteroendocrine cells. Fibroblast growth factor 10 (FGF10) plays a central role in epithelial cell proliferation, survival, and differentiation in several organs. The expression pattern of FGF10 and its receptors in both human and mouse intestine and their role in small intestine have yet to be investigated. First, we analyzed the expression of FGF10, FGFR1, and FGFR2, in the human ileum and throughout the adult mouse small intestine. We found that FGF10, FGFR1b, and FGFR2b are expressed in the human ileum as well as in the mouse small intestine. We then used transgenic mouse models to overexpress Fgf10 and a soluble form of Fgfr2b, to study the impact of gain or loss of Fgf signaling in the adult small intestine. We demonstrated that overexpression of Fgf10 in vivo and in vitro induces goblet cell differentiation while decreasing Paneth cells. Moreover, FGF10 decreases stem cell markers such as Lgr5, Lrig1, Hopx, Ascl2, and Sox9. FGF10 inhibited Hes1 expression in vitro, suggesting that FGF10 induces goblet cell differentiation likely through the inhibition of Notch signaling. Interestingly, Fgf10 overexpression for 3 days in vivo and in vitro increased the number of Mmp7/Muc2 double-positive cells, suggesting that goblet cells replace Paneth cells. Further studies are needed to determine the mechanism by which Fgf10 alters cell differentiation in the small intestine.
Microsoft Sharepoint Portal Server 2003 Unleashed (2004)

US significantly underestimates all three dimensions of the lumpectomy cavity and hence the volume at risk compared to radiographic evaluation of surgical clips. Breast-conserving surgery should include placement of clips at the margins of the lumpectomy cavity (superior, inferior, medial, lateral, and posterior) to aid in radiotherapy treatment planning. US should not be utilized to guide the design of the boost field as it will result in inappropriate selection of lower electron energies and smaller field sizes (geographical miss), particularly among patients who receive chemotherapy prior to breast radiotherapy.
Dissociation of heart rate variability from parasympathetic tone (1994)

Time and frequency domain measurements of heart rate variability have been used as indexes of parasympathetic tone. This study evaluates the effects of parasympathetic stimulation on these indexes. Ten normal subjects (5 females, 5 males; age 27.4 +/- 5.1 yr) were evaluated in the Clinical Research Center. Five-minute electrocardiographic recordings were obtained at baseline and during 1) combined alpha-adrenergic stimulation with baroreflex-increased cardiac parasympathetic activity produced by phenylephrine infusion; 2) parasympathetic blockade (atropine 0.04 mg/kg); and 3) isolated alpha-adrenergic stimulation produced by phenylephrine infusion after parasympathetic blockade. The infusion rate of phenylephrine was titrated to increase the systolic blood pressure by 20-30 mmHg. Heart rate variability analysis was performed using standard time and frequency domain parameters. Phenylephrine infusion resulted in a decrease in the time domain measures and in the high-frequency power. After parasympathetic blockade, alpha-adrenergic stimulation had no significant effect on the heart rate variability parameters. These findings suggest that the heart rate variability parameters traditionally associated with parasympathetic tone do not always reliably measure parasympathetic tone, since they decrease with baroreflex parasympathetic stimulation.

Parallel Algorithms for Computation of the Manipulator Inertia Matrix (1991)

This article presents the development of an O( log 2 N) parallel algorithm for the manipulator inertia matrix. It is based on an efficient serial algorithm that uses the composite rigid- body method. Recursive doubling is used to reformulate the linear recurrence equations that are required to compute the diagonal elements of the matrix. It results in O( log 2 N) levels of computation. Computation of the off-diagonal ele ments involves N linear recurrences of varying size, and a new method, which avoids redundant computation of position and orientation transforms for the manipulator, is developed. The O( log 2 N) algorithm is presented in both equation and graphic forms that clearly show the parallelism inherent in the algorithm. The relationship between the number of pro cessors required and the order of the computation is also given for several versions of parallel algorithms for the inertia matrix.
Immunohistochemical Analysis of p18INK4C and p14ARF Protein Expression in 117 Oligodendrogliomas (2002)

p18 protein expression is closely associated with malignant oligodendrogliomas and worse clinical outcome. It seems unlikely that p14 immunohistochemistry will be of value in assessing individual prognosis for these tumors.
