Improved Magnetron Stability And Reduced Noise In Efficient Transmitters For Superconducting Accelerators (2018)

State of the art high-current superconducting accelerators require efficient RF sources with a fast dynamic phase and power control. This allows for compensation of the phase and amplitude deviations of the accelerating voltage in the Superconducting RF (SRF) cavities caused by microphonics, etc. Efficient magnetron transmitters with fast phase and power control are attractive RF sources for this application. They are more cost effective than traditional RF sources such as klystrons, IOTs and solid-state amplifiers used with large scale accelerator projects. However, unlike traditional RF sources, controlled magnetrons operate as forced oscillators. Study of the impact of the controlling signal on magnetron stability, noise and efficiency is therefore important. This paper discusses experiments with 2.45 GHz, 1 kW tubes and verifies our analytical model which is based on the charge drift approximation.
High-Rate Li+Storage Capacity of Surfactant-Templated Graphene-TiO2Nanocomposites (2015)

Graphene-TiO2 nanocomposites are a promising anode material for Li-ion batteries due to their good high-rate capacity, inherent safety, and mechanical and chemical robustness. However, despite a large number of scientific reports on the material, the mechanism of the enhanced high-rate Li+ storage capacity that results from the addition of graphene to TiO2 – typically attributed to improved electrical conductivity – is still not well understood. In this work, we focus on optimizing the processing of surfactant-templated graphene-TiO2 hybrid nanocomposites. Towards this end, we examine the influence of various processing parameters, in particular the surfactant-mediated colloidal dispersion of graphene, on the material properties and electrochemical performance of graphene-TiO2. We investigate the influence of electrode mass loading on Li+ storage capacity, focusing mainly on high-rate performance. Furthermore, we demonstrate an approach for estimating power loss during charge/discharge cycling, which offers a succinct method for characterizing the high-rate performance of Li-ion battery electrodes.
Minkowski and KZ reduction of nearly orthogonal lattice bases (2011)

We prove that if a lattice basis is nearly orthogonal (the angle between any basis vector and the linear subspace spanned by the other basis vectors is at least 3 radians), then a KZ-reduced basis can be obtained from it in polynomial time. We also show that if a nearly orthogonal lattice basis has nearly equal vector lengths (within a certain constant factor of one another), then the basis is Minkowski reduced. We use these results to show thatmi.i.d. random vectors drawn from a uniform distribution over the unit ball in R n form a Minkowski-reduced basis of the lattice generated by the vectors asymptotically almost surely as n tends to infinity, if m cn for any constant c < 1/4, and form a KZ-reduced basis for c < 1/5. The result on Minkowski reduction in lattices generated by random vectors extends a result of Donaldson (1979) who proved this property for fixed m as n tends to infinity.
Efficient signal coding with hierarchical lapped transforms (2002)

The hierarchical lapped transform (HLT) is defined. It is based on the modulated lapped transform (MLT). The HLT has a much lower computational complexity than a tree-structured QMF filter bank, and so with HLTs a much larger number of bands can be used in practice. The coding gain of HLTs is close to that of a full-length MLT, for the same number of bands, and therefore there is no significant loss of coding efficiency. With HLTs transient signals can be better reconstructed than with nonhierarchical transforms, as demonstrated by speech and image coding examples. In image coding applications, the HLT can also be used for progressive transmission.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Identification of Threshold Prostate Specific Antigen Levels to Optimize the Detection of Clinically Significant Prostate Cancer by Magnetic Resonance Imaging/Ultrasound Fusion Guided Biopsy (2014)

Prostate cancer upgrading with targeted biopsy increases with an increasing prostate specific antigen cutoff. Above a prostate specific antigen threshold of 5.2 ng/ml most upgrading to clinically significant disease was achieved by targeted biopsy. In our population this corresponded to potentially sparing biopsy in 36% of patients who underwent multiparametric magnetic resonance imaging. Below this value 12-core biopsy detected more clinically insignificant cancer. Thus, the diagnostic usefulness of targeted biopsy is optimized in patients with prostate specific antigen 5.2 ng/ml or greater.

The size and the density of a chip containing 4250 bits with a penny as background are illustrated, and the enlarged view of the same chip is shown. The high density is made possible by improving flux closures in both the easy and hard directions through the use of thin conductors, thin insulations, and Permalloy keepers. The device storage stability is enhanced to permit NDRO operation through the use of multiple-pulse write and/or hard-direction bias fields.

A Simple Clockless Network-on-Chip for a Commercial Audio DSP Chip (2006)

We design a very small, packet-switched, clockless network-on-chip (NoC) as a replacement for the existing crossbar-based communication infrastructure in a commercial audio DSP chip. Both solutions are laid out in a 0.18 mum process, and compared in terms of area, power consumption and routing complexity. Even though the NoC turns out to be larger and more power consuming than the existing crossbar implementation, it still accounts for less than 1% of the total chip area and power consumption, and is justified by a long list of advantages: the NoC is modular, scalable and in contrast to the existing crossbar, it allows all blocks to communicate. The total wire length is decreased by 22% which eases the layout process and makes the design less prone to routing congestion. Not least, the communicating blocks are decoupled by means of the NoC, providing a globally-asynchronous, locally-synchronous (GALS) system where independent clocking of the individual blocks is enabled. This study shows that NoCs are feasible even for small systems
Free energy-based reinforcement learning using a quantum processor (2017)

Recent theoretical and experimental results suggest the possibility of using current and near-future quantum hardware in challenging sampling tasks. In this paper, we introduce free energy-based reinforcement learning (FERL) as an application of quantum hardware. We propose a method for processing a quantum annealer's measured qubit spin configurations in approximating the free energy of a quantum Boltzmann machine (QBM). We then apply this method to perform reinforcement learning on the grid-world problem using the D-Wave 2000Q quantum annealer. The experimental results show that our technique is a promising method for harnessing the power of quantum sampling in reinforcement learning tasks.
Fabrication of holey-fiber-based optical patch cords with bending insensitivity and their feasible reliability (2008)

We propose the holey-fiber-based optical cord cables with the excellent optical characteristics in terms of attenuation loss, insertion loss, and bending loss for the application to access network like FTTH. The attenuation loss of the holey-fiber- based cord cable with the length of 1 km at 1383 nm is as low as ~0.323 dB/km. The bending loss under the bending diameter of 5.5 mm is measured to be ~0.04 dB. We also test the proposed holey-fiber-based optical cable for E-PON transmission systems by measuring the internet speed in the server under the bending diameter of 7, 3, and 1 cm.
Evaluation of Two-Beam Spectroscopy as a Plasma Diagnostic. (1980)

A two-beam spectroscopy (TBS) system is evaluated theoretically and experimentally. This new spectroscopic technique uses correlations between components of emitted light separated by a small difference in angle of propagation. It is thus a non-perturbing plasma diagnostic which is shown to provide local (as opposed to line-of-sight averaged) information about fluctuations in the density of light sources within a plasma - information not obtainable by the usual spectroscopic methods. The present design is an improvement on earlier systems proposed in a thesis by Rostler.
A new method of forming a thin single-crystal silicon diaphragm using merged epitaxial lateral overgrowth for sensor applications (1991)

Merged epitaxial lateral overgrowth (MELO) of silicon was combined with an SiO/sub 2/ etch stop to form a 9- mu m-thick and 250- mu m*1000- mu m single-crystal Si membrane for micromechanical sensors. When epitaxial lateral overgrowth (ELO) silicon merges on SiO/sub 2/ islands, it forms a local silicon-on-insulator (SOI) film of moderate doping concentration. The SiO/sub 2/ island then acts as a near-perfect etch top in a KOH- or ethylenediamine-based solution. The silicon diaphragm thickness over a 3-in wafer has a standard deviation of 0.5 mu m and is precisely controlled by the epitaxial silicon growth rate ( approximately=0.1 mu m/min) rather than by conventional etching techniques. Diodes fabricated in the substrate and over MELO regions have nearly identical reverse-bias currents, indicating good quality silicon in the membrane.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Impact of TOF information in OpenPET imaging (2013)

We are developing an open-type PET geometry that we named OpenPET. One possible geometry is the dual-ring OpenPET, which consists of two detector rings separated by a gap for entrance of the radiation beam. The gap can also be used for different modalities such as X-ray CT to realize a simultaneous multi-modality system. In addition, the dual-ring OpenPET has an effect to enlarge the axial field-of-view. In our previous simulations and experiments the OpenPET imaging geometry was shown to be feasible by applying iterative reconstruction methods. However, the gap violates Orlov's completeness condition for accurate tomographic reconstruction. Therefore, the gap could lead to artifacts caused by lost low-frequency components in the projection data depending on the shapes of imaging subjects. In this study, we investigate the effect of time-of-flight (TOF) information, which is expected to compensate for the lost low-frequency components in OpenPET imaging. We simulated the dual-ring OpenPET geometry with a numerical phantom and analyzed frequency components of the reconstructed images. The result showed that the low-frequency components were not fully estimated in the gap region of the dual-ring OpenPET while those components were well recovered with the TOF information.
Modeling the Output Impedance of a T-Type Power Converter (2016)

The impact of operating point dependent switching time delays on the output characteristic of a T-type half-bridge is investigated for dc-dc operation. It is found that a series connection of operating point dependent components, i.e., a differential resistance and a voltage source, can accurately reproduce the implications of these switching time delays on the response of the output current of the half-bridge to a step of the duty cycle. This letter details the calculation of these components and verifies the derived expressions by means of experimental results.

Fluorine Tagging of Polyoxometalates: The Cyclic [{MoV2O4(H2O)}4{O3PC(CF3)(O)PO3}4]12– (2010)

Abstract We have discovered a simple and efficient strategy to incorporate fluorine into polyoxometalates by reaction of thefluorinated diphosphonate H 2 O 3 PC(CF 3 )(OH)PO 3 H 2 with [Mo V 2 O 4 (H 2 O) 6 ] 2+ in aqueous medium (pH = 6.4) resulting in [{Mo V 2 O 4 (H 2 O)} 4 {O 3 PC(CF 3 )(O)PO 3 } 4 ] 12– ( 1 ), which was structurally characterized in solution by multinuclear NMR spectroscopy and in the solid state by single‐crystal X‐ray diffraction, infrared, thermogravimetric and elemental analyses. Polyanion 1 crystallizes as the mixed sodium/guanidinium salt Na 6.5 [(H 2 N) 3 C] 5.5 [{Mo V 2 O 4 (H 2 O)} 4 {O 3 PC(CF 3 )(O)PO 3 } 4 ] · 8H 2 O ( 1a ) in the monoclinic system, space group C 2/ c with the unit‐cell parameters a = 34.0685(95) Å, b = 8.0874(19) Å, c = 34.4101(10) Å, β = 100.20(2)°, V = 9331.02(4) Å 3 and Z = 2. The novel polyanion 1 has a cyclic, saddle‐like structure with four {Mo 2 O 4 (H 2 O)} units linked by four fully deprotonated diphosphonate moieties. In addition, the (CF 3 )C–OH moiety is deprotonated, due to the electronic effects of the neighboring CF 3 group, leading to the formation of an Mo–O(C) bond. Solution 31 P and 19 F NMR studies of 1 indicate magnetic inequivalence of the two phosphorus atoms in each diphosphonate moiety. The solid‐state packing of the title polyanions in 1a by loosely bound Na + counterions leads to an AAA‐type arrangement.
Deciphering adaptor specificity in GFL‐dependent RET‐mediated proliferation and neurite outgrowth (2007)

Glial cell derived neurotrophic factor (GDNF)-dependent receptor tyrosine kinase RET activity is required for proper development of the nervous system and genitourinary tract. Loss-of-function mutations in RET are associated with enteric nervous system abnormalities (Hirschsprung disease) and renal deficits (Potter's syndrome), whereas activating mutations lead to hereditary cancer syndromes (multiple endocrine neoplasia type 2A and type 2B). RET activation is crucial for the proper regulation of a variety of cellular processes including cell migration, proliferation and neurite outgrowth. By analyzing a series of RET mutants we found that Y1062 was critical for stimulating GDNF-mediated proliferation as well as proliferation stimulated by GDNF-independent oncogenic forms of RET. Studies using small interfering RNA driven by lentivirus to knock-down expression of particular adaptor proteins that interact with RET phospho-Y1062, demonstrated that only Src-homology 2 and growth factor receptor binding protein 2 were necessary for RET-mediated proliferation by wild type and oncogenic forms of RET. Interestingly, we discovered that Y1062 was also required for GDNF-stimulated neurite outgrowth. However, small interfering RNAs to either Src-homology 2 or growth factor receptor binding protein 2 or a panel of other adaptor proteins known to interact with RET Y1062 were incapable of blocking GDNF-stimulated neurite formation, indicating that differential use of intracellular adaptors is responsible for regulating alternative RET-stimulated cellular events such as proliferation versus a differentiation response like neurite outgrowth.

Numerous optimizations were used in the analog circuits to achieve this power reduction. PLLs were designed to have low analog V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">min</sub> to enable operation without the use of a dedicated voltage rail. This enabled system level power optimization that yielded 28% lower power on that rail. Zero Distribution Latency to Full Distribution Latency (ZDL-to-FDL) mode was introduced in the PLLs, reducing clock distribution power and achieving ~150mV reduction in the clock distribution supply's V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">min</sub> . DDR power was reduced by 3x through the use of VTT termination, instead of the traditional Center Tapped Termination (CTT). A new package Cstate (C7+) was introduced to reduce integrated voltage regulator losses under low load conditions. Duty cycling of the thermal sensor reduced average power 10x relative to the prior generation while a fast wakeup technique reduced convergence time to ~10us.
The Presence of Pretransplant HLA Antibodies Does Not Impact the Development of Chronic Lung Allograft Dysfunction or CLAD-Related Death (2016)

Although in previous studies we have shown an increased incidence of antibody-mediated rejection in patients with pretransplant DSA, neither the presence of HLA antibodies nor DSA translated to an increased risk of allograft dysfunction or death if prospective crossmatch testing was negative. Prospective studies are needed to define the impact of pretransplant sensitization on lung transplant recipients.
