Neither chemotherapy regimen meaningfully improved response rate, event-free survival, or overall survival relative to previous series of patients with brainstem gliomas who received radiotherapy with or without chemotherapy.
Low cost varying synthetic wavelength technique for absolute distance measurement (2010)

A new low-cost superheterodyne configuration, without acousto-optic modulator, is applied to the two-wavelength interferometry for absolute distance measurement. The principle relies on a synchronized frequency sweep of two optical signals, but with different frequency excursions. The frequency difference between the two optical waves is highly accurate. This is realized by injecting a frequency modulated laser signal in an intensity modulator that is biased at halfwave voltage and driven by a digitally swept radio-frequency signal between 13 and 15 GHz. This latter is a continuous up and down ramp. The two synchronized optical signals emerging from the modulator produce in a Michelson interferometer a distance dependent superheterodyne signal, with a variable synthetic wavelength of about 10 mm. The superheterodyne frequency depends linearly on distance and on the radio-frequency excursion. The integration time for a distance measurement point corresponds to the duration of single sweep (i.e. one millisecond in our case). Absolute distance measurements from 1 to 15 meters yield an accuracy of ±50 μm, showing the validity of the technique.
Relative Contributions of Inelastic and Elastic Diffuse Phonon Scattering to Thermal Boundary Conductance Across Solid Interfaces (2009)

The accuracy of predictions of phonon thermal boundary conductance using traditional models such as the diffuse mismatch model (DMM) varies depending on the types of material comprising the interface. The DMM assumes that phonons, undergoing diffuse scattering events, are elastically scattered, which drives the energy conductance across the interface. It has been shown that at relatively high temperatures (i.e., above the Debye temperature) previously ignored inelastic scattering events can contribute substantially to interfacial transport. In this case, the predictions from the DMM become highly inaccurate. In this paper, the effects of inelastic scattering on thermal boundary conductance at metal/dielectric interfaces are studied. Experimental transient thermoreflectance data showing inelastic trends are reviewed and compared to traditional models. Using the physical assumptions in the traditional models and experimental data, the relative contributions of inelastic and elastic scattering to thermal boundary conductance are inferred.
A Novel Triangular Trinuclear μ3-CO3 Ferromagnetic CuII Compound Prepared in situ from CO2 Uptake in Air. X-ray Structure, Spectroscopy and Magnetism (2000)

The new trinuclear compound [Cu3(bpy)6(μ3-CO3)](BF4)4(H2O)2(C2H6O) (in which bpy = 2,2′-bipyridine) has been synthesized from Cu(BF4)2 and bpy in aqueous ethanol by rapid uptake of atmospheric CO2. The structure of the compound has been determined by X-ray crystallography; it was found to crystallise in the triclinic space group P1¯ with a = 13.405(7), b = 13.691(7), c = 21.446(8) Å, α = 82.87(4), β = 73.57(4), γ = 64.32(4)°, Z = 2. The three copper atoms are connected to each other through the oxygen atoms from the bridging carbonato group, giving a triangular array of copper atoms. Each copper has a distorted square-pyramidal environment with a basal plane formed by three nitrogen atoms of the two chelating bipyridine groups and the oxygen atom of the bridging carbonato group (Cu−N/O distances about 2.0 Å). The apical position is formed at each copper by the fourth nitrogen atom of the bipyridines with distances varying from 2.120(5) to 2.188(5) Å. A weak ferromagnetic interaction is observed between the copper(II) ions. All data were fitted using the Hamiltonian H = −J12 (S1·S2) −J13 (S1·S3) −J23 (S2·S3). Observed parameters are J = 10.6 cm−1 and a very weak antiferromagnetic intercluster interaction with zj′ = −1.2 cm−1.
Designing patient-specific orthopaedic mesh implants to treat high-energy tibial fractures (2011)

High energy fractures of the tibia can frequently lead to segmental bone loss. Due to delayed fracture healing caused by poor blood flow, increased mechanical demands are placed on the fracture fixation devices, which can lead to premature failure. However, these methods have proven to be insufficient for fractures with segmental bone loss because they lack the combination of providing acute stability for early weight bearing, a platform for bony ingrowth, and long-term stability. These limitations can often result in amputation. The purpose of this project was to develop a mesh implant possessing a shape that mimics the profile of the bone fracture using rapid prototyping techniques. The first aim of this study was to develop the methods for designing a patient-specific orthopaedic implant of a high energy fracture. The second aim was to computationally assess the custom implant using finite element analyses. Our third aim is to fabricate rapidly manufactured implants, and experimentally load them to test the accuracy of the computational model.
Laboratory investigations of meteorite luminescence (1967)

Abstract Apparatus has been constructed for the irradiation of mineral dust samples with protons and ultraviolet radiation. The spectrum of any resulting luminescence emission is scanned by a photoelectric grating spectrophotometer. A range of meteorites of different classes has been investigated; only the enstatite achondrites luminesce strongly. The enstatite constituent is responsible for the luminescence, but the emission may be predominantly red or blue; there is some evidence that the difference between these two conditions is one of manganese content. Several other classes of meteorite luminesce weakly; some spectra are given, showing changes with proton damage.
A Hidden Markov Model for Single Particle Tracks Quantifies Dynamic Interactions between LFA-1 and the Actin Cytoskeleton (2009)

The extraction of hidden information from complex trajectories is a continuing problem in single-particle and single-molecule experiments. Particle trajectories are the result of multiple phenomena, and new methods for revealing changes in molecular processes are needed. We have developed a practical technique that is capable of identifying multiple states of diffusion within experimental trajectories. We model single particle tracks for a membrane-associated protein interacting with a homogeneously distributed binding partner and show that, with certain simplifying assumptions, particle trajectories can be regarded as the outcome of a two-state hidden Markov model. Using simulated trajectories, we demonstrate that this model can be used to identify the key biophysical parameters for such a system, namely the diffusion coefficients of the underlying states, and the rates of transition between them. We use a stochastic optimization scheme to compute maximum likelihood estimates of these parameters. We have applied this analysis to single-particle trajectories of the integrin receptor lymphocyte function-associated antigen-1 (LFA-1) on live T cells. Our analysis reveals that the diffusion of LFA-1 is indeed approximately two-state, and is characterized by large changes in cytoskeletal interactions upon cellular activation.
Possible Mechanism of Urea Toxicity in Ruminants. (1955)

Administration of ammonium carbamate either orally or intravenously produced symptoms in ruminating lambs similar to those observed during acute urea toxicity. It is proposed that urea toxicity in the ruminant is not due to ammonia, but to ammonium carbamate. It is suggested that conditions exist in the rumen after the oral administration of urea which would lead to the formation of ammonium carbamate.
Self Assembly through Sonication: An Expeditious and Green Approach for the Synthesis of Organic‐Inorganic Hybrid Nanopetals and their Application as Biocatalyst (2018)

Abstract The present study exhibits a facile method for the expeditious synthesis of organic‐inorganic hybrid nanoassemblies. Pseudomonas fluorescens lipase was immobilized on the nanoassembly and its application as a nanobiocatalyst was demonstrated. Scanning electron microscopy analysis depicted petal‐like morphology of the newly synthesized hybrid. The sonochemical method screened as a faster route for the synthesis of hybrid nanopetals with a marked increase in enzyme activity (15 folds). Furthermore, an additional treatment of the hybrid nanopetals with chemical modifiers likes 1‐ethyl‐3‐(3‐dimethylaminopropyl)‐carbodiimide (EDC) exhibited improved stability and reusability upto six cycles. A systematic investigation of the reaction parameters influencing the formation of lipase‐embedded hybrid nanopetals was done. In addition, the nanobiocatalytic potential of hybrid nanopetals was explored in the kinetic resolution of racemic secondary alcohols.
PREDICTING GROUND-BASED AEROSOL OPTICAL DEPTH WITH SATELLITE IMAGES VIA GAUSSIAN PROCESSES (2010)

A Gaussian process regression technique is proposed to predict ground-based aerosol optical depth measurements from satellite multispectral images, and to select the most informative ground-based sites by active learning. Satellite images provide spatial and temporal information in addition to the spectral features, and such heterogeneity of available features is captured in the Gaussian process model by employing an additive set of covariance functions. By finding an optimal set of hyperparameters, relevance of each additional information is automatically determined. Experiments show that the spatio-temporal information contributes significantly to the regression results. The prediction results are not only more accurate but also more interpretable than existing approaches. For active learning, each spatio-temporal setup is evaluated by an uncertainty-sampling algorithm. The results show that the active selection process benefits most from the spatial information.
On MIMO Detection Under Non-Gaussian Target Scattering (2010)

In this paper, we consider a multiple-input-multiple-output (MIMO) detection problem with <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">M</i> widely spaced transmit antennas and <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">L</i> widely spaced receive antennas, and we study the problem of designing the signal waveforms transmitted by each source node under non-Gaussian target scattering and temporally correlated Gaussian clutter. Two figures of merit are investigated for space-time code (STC) optimization under a semidefinite rank constraint: 1) the lower Chernoff bound (LCB) to the detection probability for fixed probability of false alarm, and 2) the mutual information (MI) between the observations available at the receive nodes and the “channel response” generated by a point-like target, assumed present tout court. Both receive and transmit power constraints are discussed. If the scattering distribution possesses some suitably defined properties of unitary invariance (see Section II-B), both MI-optimal and LCB-optimal STCs have a simple canonical structure: the same set of (clutter dependant) temporal codewords are employed at the transmit nodes, the only difference among the many solutions being the amount of power radiated by each antenna. Such a spatial power allocation critically depends upon the adopted figure of merit, the specified power constraint, and the underlying scattering model. Sufficient conditions to determine the optimal power allocation for all design criteria are provided. Asymptotic power distributions are also derived in the limit of vanishingly small and increasingly large signal-to-clutter ratios, proving that assuming Gaussian scattering at the design stage is a robust choice. A case study of relevant practical interest is examined in depth so as to compare the proposed design criteria and to assess the impact of signal non-Gaussianity on the system performances.
Assessment of trace-differences in timing analysis for Complex Real-Time Embedded Systems (2011)

In this paper, we look at identifying temporal differences between different versions of Complex Real-Time Embedded Systems (CRTES) by using timing traces representing response times and execution times of tasks. In particular, we are interested in being able to reason about whether a particular change to CRTES will impact on their temporal performance, which is difficult to answer due to the complicated timing behavior such CRTES have. To be specific, we first propose a sampling mechanism to eliminate dependencies existing in tasks' response time and execution time data in the traces taken from CRTES, which makes any statistical inference in probability theory and statistics realistic. Next, we use a mature statistical method, i.e., the non-parametric two-sample Kolmogorov-Smirnov test, to assess the possible temporal differences between different versions of CRTES by using timing traces. Moreover, we introduce a method of reducing the number of samples used in the analysis, while keeping the accuracy of analysis results. This is not trivial, as collecting a large amount of samples in terms of executing real systems is often costly. Our evaluation using simulation models describing an industrial robotic control system with complicated tasks' timing behavior, indicates that the proposed method can successfully identify temporal differences between different versions of CRTES, if there is any. Furthermore, our proposed method outperforms the other statistical methods, e.g., bootstrap and permutation tests, that are often widely used in contexts, in terms of bearing on the accuracy of results when other methods have failed.
Proteomic Profiling of Interactions Comprising the Beta 2 Subunit of the Nicotine Receptor Using MALDI‐TOF MS Analysis (2007)

Nicotine acetylcholine receptors form a family of membrane channel proteins expressed throughout the nervous system. In response to ligand activation nicotine receptors modulate important processes such as neurotransmitter release and synaptic plasticity. We have examined protein interactions comprising the high affinity nicotine receptor beta2 site in the mouse brain by MALDI‐TOF MS analysis of receptor complexes derived from immunoprecipitation and pull‐down experiments. The validity of the nicotine receptor interacting proteins was examined in knockout mice lines with genetic deletions in the beta2 subunit.
'Patient choice' concept in AF ESC Guidelines: is the clinician giving up? Reply (2013)

Dear Sir,

I was very surprised when Professor Capucci and others first raised this matter at the ESC Annual Congress where the AF Guideline Focused Update was first presented. To most physicians it is now routine to engage their patients in a discussion of the advantages and disadvantages of various treatment options. When the physician's judgement is that a particular course of action is preferable to another, he should advise …

Review of Robust Data Exchange Using Optical Nonlinearities (2012)

Data exchange, namely bidirectional information swapping, provides enhanced flexibility compared to the unidirectional information transfer. To fulfill the rapid development of high-speed large-capacity optical communications with emerging multiplexing/demultiplexing techniques and advanced modulation formats, a laudable goal would be to achieve data exchange in different degrees of freedom (wavelength, time, polarization), for different modulation formats (OOK, DPSK, DQPSK, pol-muxed), and at different granularities (entire data, groups of bits, tributary channels). Optical nonlinearities are potentially suitable candidates to enable data exchange in the wavelength, time, and polarization domains. In this paper, we will review our recent works towards robust data exchange by exploiting miscellaneous optical nonlinearities, including the use of cSFG/DFG in a PPLN waveguide for time- (groups of bits) and channel-selective data exchange and tributary channel exchange between two WDM+OTDM signals, nondegenerate FWM in an HNLF for phase-transparent data exchange (DPSK, DQPSK), bidirectional degenerate FWM in an HNLF for multi-channel data exchange, and Kerr-induced nonlinear polarization rotation in an HNLF for tributary channel exchange of a pol-muxed DPSK OTDM signal. The demonstrated data exchanges in different degrees of freedom, for different modulation formats, and at different granularities, open the door for alternative approaches to achieve superior network performance.

D133 Performance Prediction of Oscillating Flow Steam Engine (2014)

Numerical simulation of oscillation flow steam engine is carried out. Simulation model calculates the movement of gas liquid interface, thermal conduction and phase transition. Though there are some difference between simulation results and experimental results, basic characteristics such as dependence on frequency and tube diameter can be predicted. Sensible heat is not used for phase transition but transfers from the heating section to the cooling section, which is considered to be the major cause of energy loss. Amount of liquid injection and heat transfer from cooling water have optimal values, and lower thermal conductivity material should be used for the adiabatic section.
7.4.4 Electrochemical Sensors for Environmental Monitoring in Cities (2012)

We demonstrate that miniature, low-cost electrochemical gas sensors, traditionally used for sensing at parts-per-million (ppm) mixing ratios can, when suitably configured and operated, be used for partsper-billion (ppb) level studies for gases relevant to urban air quality. The results show the sensors to be high precision and highly linear in the ppb rangeand in general highly selective, although there are some significant cross-interferences. Comparisons of the sensors with co-located reference instruments show good agreement on both short and long timescales, demonstrating their utility for urban air quality monitoring.
Studies on the Syntheses of Heterocyclic Compounds. LX (1960)

In order to examine the properties of 1, 2-dihydroisoquinoline derivatives, 2, 3-dimethyl-6, 7-methylenedioxyisoquinolinium iodide was reduced with lithium aluminium hydride to form the corresponding 1, 2-dihydroisoquinoline derivative and the latter compound was identified with the picrate of a sample prepared by a different route. It was also found that this substance is comparatively unstable in air.
A microcomputer-based control and simulation of an advanced IPM synchronous machine drive system for electric vehicle propulsion (1988)

Describes a high-performance microcomputer-based control and digital simulation of an inverter-fed interior permanent magnet (IPM) synchronous machine that uses a neodymium-iron-boron magnet. The fully operational four-quadrant drive system includes a constant-torque region with zero speed operation and a high-speed field-weakening constant-power region. The control uses the vector or field-oriented technique in constant-torque region with the direct axis aligned to the stator flux, whereas the constant-power region control is based on torque angle orientation of the impressed square-wave voltage. All the key feedback signals for the control are estimated with precision. The drive system is basically designed with an outer torque control loop for electric vehicle application, but speed and position control loops can be added for other industrial applications. The distributed microcomputer-based control system is based on Intel-8096 microcontroller and Texas Instruments TMS32010 type digital signal processor.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Application of the pencil-beam redefinition algorithm in heterogeneous media for proton beam therapy (2013)

In proton beam therapy, changes in the proton range due to lateral heterogeneity may cause serious errors in the dose distribution. In the present study, the pencilbeam redefinition algorithm (PBRA) was applied to proton beam therapy to address the problem of lateral density heterogeneity. In the calculation, the phase-space parameters were characterized for multiple range (i.e. proton energy) bins for given pencil beams. The particles that were included in each pencil beam were transported and redefined periodically until they had stopped. The redefined beams formed a detouring path that was different from that of the non-redefined pencil beams, and the path of each redefined beam was straight. The results calculated by the PBRA were compared with measured proton dose distributions in a heterogeneous slab phantom and an anthropomorphic phantom. Through the beam redefinition process, the PBRA was able to predict the measured proton-detouring effects. Therefore, the PBRA may allow improved calculation accuracy when dealing with lateral heterogeneities in proton therapy applications.
SIMART : an engineering CACSD package for process control (2002)

A general purpose computer aided control system design package called SIMART has been developed from the available control theory. Equipped with sound real-time and simulation capabilities, it is intended to serve as a control engineering framework as well as a learning basis for advanced control techniques. As a key feature, SIMART supports a structured approach to advanced control, which greatly simplifies each design step, swiftly leading to feasible controllers. SIMART has already been successfully used for a number of applications, both on industrial and laboratory plants. One of these applications, involving a flexible system, is reported at the end of the paper.
