High-Contrast Qubit Interactions Using Multimode Cavity QED (2015)

We introduce a new multimode cavity QED architecture for superconducting circuits that can be used to implement photonic memories, more efficient Purcell filters, and quantum simulations of photonic materials. We show that qubit interactions mediated by multimode cavities can have exponentially improved contrast for two qubit gates without sacrificing gate speed. Using two qubits coupled via a three-mode cavity system we spectroscopically observe multimode strong couplings up to 102 MHz and demonstrate suppressed interactions off resonance of 10 kHz when the qubits are ≈600 MHz detuned from the cavity resonance. We study Landau-Zener transitions in our multimode systems and demonstrate quasiadiabatic loading of single photons into the multimode cavity in 25 ns. We introduce an adiabatic gate protocol to realize a controlled-Z gate between the qubits in 95 ns and create a Bell state with 94.7% fidelity. This corresponds to an on/off ratio (gate contrast) of 1000.

Private Database Access With HE-over-ORAM Architecture. (2014)

Enabling private database queries is an important and challenging research problem with many real-world applications. The goal is for the client to obtain the results of its queries without learning anything else about the database, while the outsourced server learns nothing about the queries or data, including access patterns. The secure-computation-over-ORAM architecture offers a promising approach to this problem, permitting sub-linear time processing of the queries (after pre-processing) without compromising security. In this work we examine the feasibility of this approach, focusing specifically on securecomputation protocols based on somewhat-homomorphic encryption (SWHE). We devised and implemented secure two-party protocols in the semi-honest model for the path-ORAM protocol of Stefanov et al. This provides access by index or keyword, which we extend (via pre-processing) to limited conjunction queries and range queries. Some of our sub-protocols may be interesting in their own right, such as our new protocols for encrypted comparisons and blinded permutations. We implemented our protocols on top of the HElib homomorphic encryption library. Our basic single-threaded implementation takes about 30 minutes to process a query on a database with 222 records and 120-bit long keywords, providing a cause for optimism about the viability of this direction, and we expect a better optimized implementation to be much faster.

Simplified Belief Propagation for Multiple View Reconstruction (2006)

We address multiple-view reconstruction under an optimization approach based on belief propagation. A novel formulation of belief propagation that operates in 3-D is proposed to facilitate a true multi-image processing scheme that takes visibility into account and thus is applicable to scenes that contain significant occlusions. Visibility is not approximated but is estimated and used in a modified plane sweep stereo scheme. Optimization is performed in a simplified belief propagation framework in which messages are passed in 3-D, instead of 2-D, neighborhoods utilizing information from all available images. The information propagated from a point to one of its neighbors factors in the distance between the two points in 3-D, their difference in color. In contrast to traditional belief propagation, the observation is updated at each iteration to incorporate changes in visibility. The proposed approach is capable of enforcing smoothness on the evolving 3-D surfaces without being limited to a coarse resolution due to a volumetric representation. Moreover, our approach is applicable to both open and closed surfaces with no need for a priori knowledge of the type. We present dense reconstructions of publicly available image sets.

Monitoring β‐Secretase Activity in Living Cells with a Membrane‐Anchored FRET Probe (2012)

Turn it on! β-MAP is a sensitive FRET probe with specificity for monitoring the enzyme β-secretase (BACE), which is associated with Alzheimer's disease. After hydrolysis by the enzyme BACE, the probe fluoresces and thus allows real-time spatial and temporal assessment of enzymatic activity in living cells. β-MAP was used to confirm the cellular efficacy of a reported inhibitor without the need for mutated cell lines or antibodies.

Open and optimized VVC Implementations on ARM Architectures (2023)

The international video coding standard Versatile Video Coding (VVC) has been finalized in July 2020 by ITU-T and ISO/IEC. In September 2020, the open and optimized VVC encoder (VVenC) and decoder (VVdeC) software has been released and continuously improved in terms of speed and efficiency. Originally developed for x86 architecture, recent optimizations on vectorization target ARM platforms. VVenC and VVdeC runtimes have been measured on various systems to evaluate their performance. Results show that the three fastest presets for VVenC enable encoding HD video with 4 to 25 fps on high performance laptops (Apple M1 Max and Intel i9-12900H) and UHD video with 2 to 10 fps on workstations (Apple M1 Ultra and Intel Xeon Gold 6348). The VVdeC decoder enables live decoding of HD video on a tablet with octa-core ARM CPU as well as live decoding of UHD video on the afore mentioned laptops.
Bowl Geometry Effects on Turbulent Flow Structure in a Direct Injection Diesel Engine (2018)

&lt;div class="section abstract"&gt;&lt;div class="htmlview paragraph"&gt;Diesel piston bowl geometry can affect turbulent mixing and therefore it impacts heat-release rates, thermal efficiency, and soot emissions. The focus of this work is on the effects of bowl geometry and injection timing on turbulent flow structure. This computational study compares engine behavior with two pistons representing competing approaches to combustion chamber design: a conventional, re-entrant piston bowl and a stepped-lip piston bowl. Three-dimensional computational fluid dynamics (CFD) simulations are performed for a part-load, conventional diesel combustion operating point with a pilot-main injection strategy under non-combusting conditions. Two injection timings are simulated based on experimental findings: an injection timing for which the stepped-lip piston enables significant efficiency and emissions benefits, and an injection timing with diminished benefits compared to the conventional, re-entrant piston.&lt;/div&gt;&lt;div class="htmlview paragraph"&gt;While the flow structure in the conventional, re-entrant combustion chamber is dominated by a single toroidal vortex, the turbulent flow evolution in the stepped-lip combustion chamber depends more strongly on main injection timing. For the injection timing at which faster mixing controlled heat release and reduced soot emissions have been observed experimentally, the simulation predicts the formation of two additional recirculation zones created by interactions with the stepped-lip. Analysis of the CFD results reveals the mechanisms responsible for these recirculating flow structures. Vertical convection of outward radial momentum drives the formation of the recirculation zone in the squish region, while adverse pressure gradients drive flow inward near the cylinder head, thereby contributing to the formation of the second recirculation zone above the step. Bulk gas density is higher for the near-TDC injection timing than for the later injection timing. This leads to increased air entrainment into the sprays and slower spray velocities, so the sprays take longer to interact with the step, and beneficial recirculating flow structures are not obseved.&lt;/div&gt;&lt;/div&gt;
Synthesis of Hierarchically Grown ZnO@NT-WS2 Nanocomposites (2009)

A chemically specific and facile method for growth of ZnO nanorods on WS2 nanotubes (NT-WS2) is reported. The modification strategy is based on the chalcophilic affinity of Zn, which serves as an anchor to immobilize ZnO colloids onto the WS2 nanotubes. The surface bound ZnO colloids have been used as a seed to grow ZnO nanorods on WS2 nanotubes. The immobilization of ZnO colloids was monitored by UV−vis spectroscopy and photoluminescence spectroscopy whereas the growth of ZnO nanorods was characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM).
Monitoring Nanostructure Dynamics and Polymerization in Glycerol Plasticized Wheat Gliadin and Glutenin Films: Relation to Mechanical Properties (2016)

Gliadin and glutenin proteins with 10, 20, 30 and 40% of glycerol were compression molded into films (130 °C) and evaluated for protein polymerization, β-sheet structure and nano-structural morphology. Here, for the first time we show how different amounts of glycerol impact the nano-structure and functional properties of the gliadin and glutenin films. Most polymerized protein was found in the gliadin films with 20 and 30% glycerol, and in all the glutenin films (except 10%), by RP-HPLC. A β-sheet-rich protein structure was found to be high in the 10 and 20% glycerol gliadin films, and in the 20 and 30% glycerol glutenin films by FT-IR. Glycerol content of 20, 30 and 40% impacted the nano-structural morphology of the gliadin glycerol films observed by SAXS, and to a limited extent for 10 and 20% glycerol gliadin films revealed by WAXS. No ordered nano-structure was found for the glutenin glycerol films. The 20%, 30% and 40% glycerol films were the most tunable for specific mechanical properties. For the highest stiffness and strength, the 10% glycerol protein films were the best choice.
FOS: A Factored Operating Systems for High Assurance and Scalability on Multicores (2012)

Abstract : fos is a new operating system design for multicores and cloud computing. It builds on previous work in distributed and microkernel OSes by factoring services out of the kernel, and then further distributing each service into a parallel, distributed fleet of cooperating processes. This design naturally spans non-coherent shared memory architectures and clusters of machines. Additionally it provides increased isolation between and within services, giving opportunities for increased reliability. This report describes the general design principles of fos as well as the implementation of several specific services with evaluation of their scalability (e.g., naming, page allocation, and network stack). It also describes two distributed data structures (dPool and key-value store) that we implement to ease implementation of fos system services.
Estimating the efficiency of collaborative problem-solving, with applications to chip design (2003)

We present a statistical framework to address questions that arise in general problems involving collaboration of several contributors. One instance of this problem occurs in the complex process of designing ultralarge-scale-integration (ULSI) semiconductor chips. In these processes, computer-aided design tools are treated as “black boxes.” In most cases, the automated design tools operate on designs and successfully complete a specified task to create designs that satisfy specified design criteria. In other cases involving complex designs, however, the tools are unable to create designs that satisfy the specified criteria. In both situations, the performance of the tools can be enhanced with systematic external intervention that is implemented with some supplemental algorithm. This algorithm can either be fully automated or be implemented by hand, relying on formally describable human expertise. In this intervention, the supplemental algorithm and the automated design tool take turns to move the design from one configuration to another until either the task is complete or further improvements are not possible or necessary. In such a setting, a number of questions arise about how to measure the effectiveness of the external intervention. One question, for example, is whether the external intervention consistently assists the progress of the automated program. This situation is an instance of a general problem that we address in this paper. As an example, we apply the statistical framework to the problem of routing a functional unit of the IBM POWER4 microprocessor.
Effectiveness of Metanx Prescription Medical Food on Small Nerve Fibers and Monofilament Sensation in Patients with Diabetic Peripheral Polyneuropathy (2016)

Purpose: Diabetic peripheral neuropathy (DPN) is prevalent among the population with type 2 diabetes, and treatment approaches are limited. The combination of L-methylfolate-methylcobalamin-pyridoxal-5-phospate (LMF-MC-PP, Metanx?) is a prescription medical food that has demonstrated significant improvements in sensory perception and quality of life as well as reduced neuropathic pain in patients with DPN. The present study examined the effects of LMF-MC-PP on sensory perception and epidermal nerve fiber density (ENFD) among patients with confirmed DPN. Methods: Patients with type 2 diabetes and diagnosed with diabetic peripheral polyneuropathy, based on loss of vibratory perception, warm-cold discrimination or monofilament sensation, underwent bilateral lower extremity ENFD assessments via skin punch biopsy and were started on LMF-MC-PP. ENFD and monofilament testing were repeated at 6 months. Findings: Of 123 patients evaluated, all had monofilament testing at baseline and 6 months and 122 had assessments at both time points. A significant (p
A Feedforward and Feedback Constant-Slope Digital-to-Time Converter in 28nm CMOS Achieving ≤ 0.12% INL/Range over >100mV Supply Range (2021)

Advanced techniques focusing on ultra-low jitter and spurs in integer-N PLLs, such as subsampling, injection locking and type-I architectures, have been extensively explored in the last decade. To accommodate new communication protocols, it is more attractive to push these high performance PLLs to a fractional-N operation. One major issue related to the fractional-N PLLs are fractional spurs, especially the in-band spurs that cannot be simply filtered out by the PLL loop but which can ruin the spectral performance. Phase interpolators (PI) and digital-to-time converters (DTC) are commonly used to assist in reducing the phase detection quantization error. The linearity, range, jitter and power are the main trade-offs in these blocks’ design. A DTC with >9-b (<0.2% INL/range) linearity is favored in the fractional-N PLLs targeting <-50dBc in-band fractional spurs. This work presents techniques to minimize the nonlinearities and power in the proposed constant slope DTC. Figure 1 shows the complete schematic of the proposed design. With feedforward (FF) and feedback (FB) techniques and nonlinearity cancellation, the implemented DTC runs at 50MHz and features 543ps delay range, 0.11% INL/Range, 36uW power consumption.
Constraints on the shallow elastic and anelastic structure of Mars from InSight seismic data (2020)

Mars’s seismic activity and noise have been monitored since January 2019 by the seismometer of the InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) lander. At night, Mars is extremely quiet; seismic noise is about 500 times lower than Earth’s microseismic noise at periods between 4 s and 30 s. The recorded seismic noise increases during the day due to ground deformations induced by convective atmospheric vortices and ground-transferred wind-generated lander noise. Here we constrain properties of the crust beneath InSight, using signals from atmospheric vortices and from the hammering of InSight’s Heat Flow and Physical Properties (HP3) instrument, as well as the three largest Marsquakes detected as of September 2019. From receiver function analysis, we infer that the uppermost 8–11 km of the crust is highly altered and/or fractured. We measure the crustal diffusivity and intrinsic attenuation using multiscattering analysis and find that seismic attenuation is about three times larger than on the Moon, which suggests that the crust contains small amounts of volatiles. The crust beneath the InSight lander on Mars is altered or fractured to 8–11 km depth and may bear volatiles, according to an analysis of seismic noise and wave scattering recorded by InSight’s seismometer.
[Urban heat island intensity and its grading in Liaoning Province of Northeast China]. (2012)

According to the recorded air temperature data and their continuity of each weather station, the location of each weather station, the numbers of and the distances among the weather stations, and the records on the weather stations migration, several weather stations in Liaoning Province were selected as the urban and rural representative stations to study the characteristics of urban heat island (UHI) intensity in the province. Based on the annual and monthly air temperature data of the representative stations, the ranges and amplitudes of the UHI intensity were analyzed, and the grades of the UHI intensity were classified. The Tieling station, Dalian station, Anshan station, Chaoyang station, Dandong station, and Jinzhou station and the 18 stations including Tai' an station were selected as the representative urban and rural weather stations, respectively. In 1980-2009, the changes of the annual UHI intensity in the 6 representative cities differed. The annual UHI intensity in Tieling was in a decreasing trend, while that in the other five cities was in an increasing trend. The UHI intensity was strong in Tieling but weak in Dalian. The changes of the monthly UHI intensity in the 6 representative cities also differed. The distribution of the monthly UHI intensity in Dandong, Jinzhou and Tieling took a "U" shape, with the maximum and minimum appeared in January and in May-August, respectively, indicating that the monthly UHI intensity was strong in winter and weak in summer. The ranges of the annual and monthly UHI intensity in the 6 cities were 0.57-2.15 degrees C and -0.70-4.60 degrees C, and the ranges of 0.5-2.0 degrees C accounted for 97.8% and 72.3%, respectively. The UHI intensity in the province could be classified into 4 grades, i. e., weak, strong, stronger and strongest.
Carbenium Ion (2016)

This document contains recommendations for terminology in mass spectrometry. Development of standard terms dates back to 1974 when the IUPAC Commission on Analytical Nomenclature issued recommendations on mass spectrometry terms and definitions. In 1978, the IUPAC Commission on Molecular Structure and Spectroscopy updated and extended the recommendations and made further recommendations regarding symbols, acronyms, and abbreviations. The IUPAC Physical Chemistry Division Commission on Molecular Structure and Spectroscopy’s Subcommittee on Mass Spectroscopy revised the recommended terms in 1991 and appended terms relating to vacuum technology. Some additional terms related to tandem mass spectrometry were added in 1993 and accelerator mass spectrometry in 1994. Owing to the rapid expansion of the field in the intervening years, particularly in mass spectrometry of biomolecules, a further revision of the recommendations has become necessary. This document contains a comprehensive revision of mass spectrometry terminology that represents the current consensus of the mass spectrometry community.
High-Sensitivity Detection of Slight Deformation Using Multiple SEM Images (2009)

A method is investigated for high-sensitivity detection of slight deformations, such as defects on semiconductor wafers, using multiple scanning electron microscope (SEM) images. The relationship between the signal-to-noise ratio (S/N) for shape deformation and the solid angle of electron detection is investigated using an SEM simulator to overcome the problem of low S/N in SEM images of slight shape deformations obtained using conventional SEMs. Based on the investigation, we proposed a new defect detection algorithm. Three SEM images are simultaneously acquired from a die; from these, two images are synthesized—one for enhancing deformation and one for enhancing material contrast—by a linear combination. Three more images are then acquired from the neighboring die and two images are synthesized in the same way. The images from the two dies are compared in a two-dimensional vector space spanned by the intensities of the two synthesized images to discriminate defects. Experimental results obtained using an actual SEM demonstrate that the proposed method is effective in detecting slight deformations.
