The geometric calibration of cone-beam imaging and delivery systems in radiation therapy (2006)

We propose a method to achieve the geometric calibration of cone-beam imaging and delivery systems in radiation therapy; our approach applies to devices where an X-ray source and a flat-panel detector, facing each other, move in circular orbits around the irradiated object. In order to extract the parameters of the geometry from the data, we use a light needle phantom which is easy to manufacture. A model with ten free parameters (spatial lengths and distortion angles) has been put forth to describe the geometry and the mechanical imperfections of the units being calibrated; a few additional parameters are introduced to account for residual effects (small effects which lie beyond our model). The values of the model parameters are determined from one complete scan of the needle phantom via a robust optimisation scheme. The application of this method to two sets of five counterclockwise (ccw) and five clockwise (cw) scans yielded consistent and reproducible results. A number of differences have been observed between the ccw and cw scans, suggesting a dissimilar behaviour of the devices calibrated in the two rotation modes. The description of the geometry of the devices was achieved at the sub-pixel level.
Elevated IL-15 concentrations in the sarcoidosis lung are independent of granuloma burden and disease phenotypes (2021)

Sarcoidosis is a systemic granulomatous disease predominantly affecting the lungs. The mechanisms promoting disease pathogenesis and progression are unknown, although interleukin-15 (IL-15) has been associated with the immune-mediated inflammation of sarcoidosis. Because the identification of a mechanistically based, clinically relevant biomarker for sarcoidosis remains elusive, we hypothesized this role for IL-15. Pulmonary sarcoidosis granuloma formation was modeled using trehalose 6,6'-dimicolate (TDM), which was administered into wild-type and three lineages of mice: those overexpressing IL-15, deficient in IL-15, and deficient in IL-15 receptor α. The number of granulomas per lung was counted and normalized to the wild type. IL-15 concentrations were measured in the bronchoalveolar lavage (BAL) from healthy controls and subjects with sarcoidosis in our cohort, where associations between IL-15 levels and clinical manifestations were sought. Findings were validated in another independent sarcoidosis cohort. TDM administration resulted in similar granuloma numbers across all lineages of mice. IL-15 concentrations were elevated in the BAL of both human cohorts, irrespective of disease phenotypes. In exploratory analysis, an association with obesity was observed, and various other soluble mediators were identified in the BAL of both cohorts. Although IL-15 is enriched in the sarcoidosis lung, it was independent of disease pathogenesis or clinical manifestations in our mouse model and human cohorts of sarcoidosis. An association with obesity perhaps reflects the ongoing inflammatory processes of these comorbid conditions. Our findings showed that IL-15 is redundant for disease pathogenesis and clinical progression of sarcoidosis.
A biaxial piezoelectric MEMS scanning mirror and its application to pico-projectors (2014)

In this paper, we report a two-dimensional MEMS optical scanner that actuate and detect the angular motion through the piezoelectric effect of thin film PZT. Typical scan ranges were ±12° at 25 kHz for the horizontal resonance and ±8° at 60 Hz for the vertical non-resonance, and the overall power consumption was 100 mW or less. A newly designed mechanical rib structure on the backside of the mirror was found to suppress the dynamic deformation of the mirror to the level compatible with a high definition of 720 pixels or more. A scanning laser type pico-projector was developed for demonstration.
An analytical approach to the calculation of EVM in clipped OFDM signals (2010)

One of the greatest drawbacks of OFDM communication systems is the high peak-to-average power ratio (PAPR) caused by various degrees of coherent summation in the signal generation using IFFT. Theoretical analysis of information capacities of such systems is difficult due to inaccuracies of models using mathematically unjustified assumptions about Gaussianity of distributions. The error-vector magnitude (EVM) of the signal after clipping is addressed. The EVM is calculated with no underlying model, and it is shown how it can be expressed as a power series of the number of tones. Thus it is concluded that although clipping should be minimized, the extent of minimization is channel and scenario dependent.
Comparison of three thermotherapy modalities for the ablation of mamma carcinoma in situ using thermal imaging and mapping (2007)

A larger percentage of small tumors in the breast are being detected due to effective screening programs and improved radiological diagnostic methods. For treatment, less invasive methods are preferred which are still radical but also provide a better aesthetic result. Recently, several ablation techniques have become available to locally ablate tumors in situ. In this study, the effectiveness of three ablation techniques was compared by imaging the thermal distribution and temperature mapping in vitro. The first system (KLS Martin, Trumpf, Germany) uses Nd:YAG laser light delivered through a single diffusing fiber tip which is positioned direct into the tissue or in a water-cooled needle. The second system (Olympus-Celon, Germany) uses bipolar Radio Frequency currents between electrodes in a water-cooled needle. The RF system has a temperature feedback based on tissue impedance to prevent tissue charring. The third system is a focused ultrasound system developed in the Hospital. For all three the techniques, the dynamics of temperature gradients around the probe or focus point are visualized using color Schlieren techniques in a transparent tissue model and recorded using thermocouples. The effective lesion size and tissue temperatures were determined in in vitro bovine mamma tissue. All systems were capable to heat tissue volumes up to 3 cm in diameter. The lesion growth dependent on the power input, temperature gradient around the initial power source and treatment time. Although the three systems are capable to ablate small mamma carcinoma in situ, they differ in precision, MR compatibility, invasiveness, practical use and treatment time. The real clinical effectiveness has to be proven in large patient studies with long term follow up.

Propagating quantum microwaves: towards applications in communication and sensing (2023)

Abstract The field of propagating quantum microwaves is a relatively new area of research that is receiving increased attention due to its promising technological applications, both in communication and sensing. While formally similar to quantum optics, some key elements required by the aim of having a controllable quantum microwave interface are still on an early stage of development. Here, we argue where and why a fully operative toolbox for propagating quantum microwaves will be needed, pointing to novel directions of research along the way: from microwave quantum key distribution to quantum radar, bath-system learning, or direct dark matter detection. The article therefore functions both as a review of the state-of-the-art, and as an illustration of the wide reach of applications the future of quantum microwaves will open.

Measurement of the inclusive b→τνX branching ratio (1994)

Using the L3 detector, the branching ratio BR(b → πνX) has been measured using a sample of Z → bb events tagged by high momentum and high transverse momentum leptons in one hemisphere and with missing energy in the opposite hemisphere. From a sample of 948 000 hadronic events we find BR(b → πνX) = (2.4 ± 0.7 (stat.) ± 0.8 (syst.))%.
Effectiveness of online RF fingerprinting for indoor localization (2018)

This paper proposes a method for indoor localization by introducing an online Radio Frequency (RF) fingerprinting approach instead of the traditional offline RF fingerprinting. The offline phase is a time-consuming stage where manual measurements made by the user cannot be at high accuracy due to the fact of shadowing effect that human body causes during the construction of RF radio map. Moreover, outdated RF radio map is another issue when it comes to the dynamic environment conditions (displacement of objects, moving people and/or the opening and closing of room doors). By proposing online fingerprinting, the problems mentioned above are solved by obtaining real-time RF maps and estimating an unknown location accordingly. Our method is unique when it comes to the approach, devices and the environment of deployment, and it has successfully shown up to 23% improvement in localization accuracy.
TetrahymenaTelomerase Is Active as a Monomer (2003)

Telomerase is an enzyme that utilizes an internal RNA molecule as a template for the extension of chromosomal DNA ends. The catalytic core of telomerase consists of the RNA subunit and a protein reverse transcriptase subunit, known as telomerase reverse transcriptase (TERT). It has previously been shown that both yeast and human telomerase can form dimers or multimers in which one RNA in the complex can influence the activity of another. To test the proposal that dimerization might be essential for telomerase activity, we sought to determine whether Tetrahymena thermophila telomerase is active as a dimer or a monomer. Recombinant Tetrahymena telomerase eluted from a gel filtration column at the size of a monomeric complex (one RNA plus one TERT), and those fractions showed processive telomerase activity. We were unable to detect dimerization of Tetrahymena telomerase by coprecipitation experiments, by using tags on either the TERT protein or telomerase RNA. Therefore, a majority, if not all, of the recombinant Tetrahymena telomerase in our reconstitution system is present as a monomeric complex. We were also unable to detect dimerization of native telomerase from mating and vegetative Tetrahymena cell extracts. These results demonstrate that Tetrahymena telomerase does not need to dimerize to be active and processive.
A UV Raman Lidar for monitoring water vapor (2001)

Continuous monitoring of atmospheric water vapor mixing ratio profiles, especially within the planetary boundary layer is required for weather assessment, global circulation models and atmospheric studies. Although conventional lidar techniques based on Raman scattering or differential absorption are capable of such measurements, they are usually large, expensive systems with high power lasers which pose eye safety problems. This paper describes a compact, cost effective, eye-safe, Raman lidar operating in the solar blind wavelength region that can be used for autonomous daytime and nighttime monitoring of water vapor in the lower atmosphere. The performance of the compact Raman lidar was simulated and also experimentally verified with a bread-board lidar. Daytime measurements to over 2 km and nighttime measurements to over 3 km with 10% accuracy can be obtained with less than 10 minutes of averaging.
Q-compensated reverse time migration in tilted transversely isotropic media (2020)

Anisotropy and absorption are critical to the modeling and analysis of seismic amplitude,phase, and traveltime data. To neglect any of these phenomena, which are often bothoperating simultaneously, degrades the resolution and interpretability of migrated images.However, a full accounting of anisotropy and anelasticity is computationally complex andexpensive. One strategy for accommodating these aspects of wave propagation, while keepingcost and complexity under control, is to do so within an acoustic approximation. Weset up a procedure for solving the time-domain viscoacoustic wave equation for tilted transverselyisotropic (TTI) media, based on a standard linear solid model and, from this, developa viscoacoustic reverse time migration (Q-RTM) algorithm. In this approach, amplitudecompensation occurs within the migration process through a manipulation of attenuationand phase dispersion terms in the time domain differential equations. Specifically, theback-propagation operator is constructed by reversing the sign only of the amplitude lossoperators, but not the dispersion-related operators, a step made possible by reformulatingthe absorptive TTI equations such that the loss and dispersion operators appear separately.The scheme is tested on synthetic examples to examine the capacity of viscoacoustic RTM to correct for attenuation, and the overall stability of the procedure.
Generic Deep Networks with Wavelet Scattering (2013)

We introduce a two-layer wavelet scattering network, for object classification. This scattering transform computes a spatial wavelet transform on the first layer and a new joint wavelet transform along spatial, angular and scale variables in the second layer. Numerical experiments demonstrate that this two layer convolution network, which involves no learning and no max pooling, performs efficiently on complex image data sets such as CalTech, with structural objects variability and clutter. It opens the possibility to simplify deep neural network learning by initializing the first layers with wavelet filters.
Enhanced space-shift keying (SSK) with reconfigurable antennas (2015)

In this work, we use the concept of reconfigurable antennas (RAs) in an effort to improve the performance of space shift keying (SSK). Indeed, the reconfigurable properties of RAs can be used as additional degrees of freedom in order to enhance the performance of SSK in terms of throughput, system complexity, and error performance. In this context, we propose a number of SSK-RA schemes using SSK with antenna-state selection while taking advantage of the interplay between RAs and the propagation channel. In this paper, we analyse the performance of the proposed SSK-RA schemes in Rician fading channels in terms of average spectral efficiency (ASE) and average bit error rate (ABER).We also provide several simulation examples through which we corroborate these analytical results. The proposed schemes are shown to enhance the performance of SSK both in terms of ASE and ABER. For the same ASE as SSK, SSK-RA schemes not only provide much better error performance but also considerably reduce the implementation cost and the overall system complexity.

The synthesis, isolation, purification (routine silica gel chromatography), and spectroscopic characterization of high-energy endo stereogenic-at-Ru complex isomers, generated by ring-opening/cross-metathesis (ROCM) reaction of the corresponding exo carbenes, are disclosed. We provide experimental evidence showing that an endo isomer can undergo thermal or Brønsted acid-catalyzed polytopal rearrangement, causing conversion to the energetically favored exo carbene.
Multi-User Sub-Channel, Bit and Power Allocation In IEEE 802.16 systems (2007)

IEEE 802.16 (WiMAX) is an emerging technology for medium-range wireless communications. Among the technological breakthroughs that could improve its performance, adaptive multi-user resource allocation is one of the most promising. The paper introduces a novel algorithm and provides an insight into some aspects and design issues related to this application. Numerical results rely on the channel models adopted by IEEE 802.16 and highlight the advantages and drawbacks of the selected strategies.
Adaptive circular beamforming using multi-beam structure (2010)

In this paper, a broadband beamspace adaptive microphone array that constructs a multibeam network is proposed. A beampattern synthesis method that has its frequency invariant property focusing on the desired direction only was used to form the beams. The main idea is to replace the blocking matrix and the quiescent vector in the conventional General Sidelobe Canceler (GSC) with the frequency invariant beam-pattern synthesis method. Simulation results show that this proposed method has faster convergence rate than an existing algorithm.

Automatic Image-based Gating for 4D Ultrasound (2006)

Four-dimensional (4D) ultrasound can be a powerful tool in adult and fetal echocardiography, enabling physicians to visualize planes that are not easily accessible using 2D ultrasound. However, despite the advances in the transducer technology, gating is still required to avoid motion artifacts during acquisition using mechanical probes or even 2D matrix array transducers in case of extended volume or color Doppler acquisitions. In fetal echocardiography, where an ECG signal is not readily available, image gating is used, which can both be computationally expensive and/or require user interaction. We present a new image gating technique that has both low computational requirements and is fully automatic. It is not only suitable for real-time gating of 4D ultrasound data sets during acquisition, but also suits well for lower-cost systems where computing resources are at a premium.
Zirconocene Immobilization and Activation on MgCl2-Based Supports:  Factors Affecting Ethylene Polymerization Activity (2007)

The effect of cyclopentadienyl ring substitution on the immobilization and activation of zirconocenes on supports of type MgCl2/AlRn(OEt)3-n has been investigated. Comparison of the activity of immobilized zirconocenes (RCp)2ZrCl2 in ethylene polymerization, using simple aluminum alkyls such as AlEt3 or AliBu3 as a cocatalyst, revealed a remarkable effect of the substituent R in the cyclopentadienyl ring. Low activity (<300 kg/mol bar h) was obtained with R = H or Et, but longer alkyl substituents, notably n-Pr or n-Bu, gave more than an order of magnitude increase in activity. Zirconocenes with branched substituents (i-Pr, t-Bu) were less easily immobilized and gave relatively low activity, while the activities of zirconocenes of composition Cp(RCp)ZrCl2 (R = n-Pr, n-Bu, n-pentyl) were intermediate between those of Cp2ZrCl2 and (RCp)2ZrCl2. Experiments carried out under homogeneous conditions with aluminoxane cocatalysts indicated that the effect of cyclopentadienyl ring substitution can be related to differences in the ease of formation of the active species. An inverse relationship between activity and the catalyst loading on the support was found. At a low loading of 1 μmol (n-PrCp)2ZrCl2/g support, an activity greater than 40 000 kg/mol bar h was obtained in ethylene polymerization at 70 °C, with AliBu3 as the cocatalyst. The results demonstrate that with certain MgCl2-immobilized zirconocenes it is possible to achieve very high polymerization activity without the use of methylaluminoxane or a borate activator, but the strong effect of catalyst loading on activity implies the presence of a relatively low number of active species.
