Reverse Engineering Methods for Digital Restoration Applications (2006)

Abstract In this paper we discuss the challenges of processing and converting 3D scanned data to representations suitable for interactive manipulation in the context of virtual restoration applications. We present a constrained parametrization approach that allows us to represent 3D scanned models as parametric surfaces defined over polyhedral domains. A combination of normal- and spatial-based clustering techniques is used to generate a partition of the model into regions suitable for parametrization. Constraints can be optionally imposed to enforce a strict correspondence between input and output features. We consider two types of virtual restoration methods: (a) a paint restoration method that takes advantage of the normal-based coarse partition to identify large regions of reduced metric distortion suitable for texture mapping and (b) a shape restoration approach that relies on a refined partition used to convert the input model to a multiresolution subdivision representation suitable for intuitive interactive manipulation during digital studies of historical artifacts.

NG-PON: enabling technologies for metro-access convergence (2009)

It has long been a goal of network planners to restructure their networks to reduce or eliminate fixed installations and all the operational difficulties and concerns that go along with them. Optical access networks have been a part of that goal because of their intrinsic long-distance capabilities. In practice, however, the demand for bandwidth has outpaced the supply offered by cost-effective passive optical systems. This has kept most PON deployments at a relatively modest reach (<20km) and split ratio (<32 way). Currently, NG-PON technologies such as 10 Gb/s systems, TDM, WDM, and their hybrids are coming on the scene. These potentially could increase the bandwidth capabilities on a single access fiber to many times what is practical now. The distance capabilities of these systems are also significantly improved, reaching to 60km. This may be the trigger for serious convergence of the inter-office/metro and access networks. This paper will examine the current trends in NG-PON technology, and extrapolate how these will impact the overall telecom network.
Quantum critical behavior in heavily dopedLaFeAsO1−xHxpnictide superconductors analyzed using nuclear magnetic resonance (2015)

We studied the quantum critical behavior of the second antiferromagnetic (AF) phase in the heavily electron-doped high-${T}_{c}$ pnictide, ${\mathrm{LaFeAsO}}_{1\ensuremath{-}x}{\mathrm{H}}_{x}$, by using a ${}^{75}\mathrm{As}$ and ${}^{1}\mathrm{H}$ nuclear magnetic resonance (NMR) technique. In the second AF phase, we observed a spatially modulated spin-density-wave-like state up to $x=0.6$ from the NMR spectral line shape and detected a low-energy excitation gap from the nuclear relaxation time ${T}_{1}$ of ${}^{75}\mathrm{As}$. The excitation gap closes at the AF quantum critical point (QCP) at $x\ensuremath{\approx}0.49$. The superconducting phase in a lower-doping regime contacts the second AF phase only at the AF QCP, and both phases are segregated from each other. The absence of AF critical fluctuations and the enhancement of the in-plane electric anisotropy are key factors for the development of superconductivity.
In Situ Analysis Reveals That CFTR Is Expressed in Only a Small Minority of β-Cells in Normal Adult Human Pancreas (2019)

For the first time, in situ CFTR mRNA expression in the unmanipulated pancreas has been shown to be present in only a very small minority (<1%) of normal adult β-cells. These data signal a need to move away from studying endocrine-intrinsic mechanisms and focus on elucidation of exocrine-endocrine interactions in human cystic fibrosis.
Location Privacy via Private Proximity Testing. (2011)

We study privacy-preserving tests for proximity: Alice can test if she is close to Bob without either party revealing any other information about their location. We describe several secure protocols that support private proximity testing at various levels of granularity. We study the use of “location tags ” generated from the physical environment in order to strengthen the security of proximity testing. We implemented our system on the Android platform and report on its effectiveness. Our system uses a social network (Facebook) to manage user public keys. 1
Bayesian Network structure learning: Hybridizing complete search with independence tests (2015)

Exponentially more precise quantum simulation of fermions II: Quantum chemistry in the CI matrix representation (2015)

We present a quantum algorithm for the simulation of molecular systems that is asymptotically more efficient than all previous algorithms in the literature in terms of the main problem parameters. As in the first paper of this series (arXiv:1506.01020), we employ a recently developed technique for simulating Hamiltonian evolution using a truncated Taylor series to obtain logarithmic scaling with the inverse of the desired precision. The algorithm of this paper involves simulation under an oracle for the sparse, first quantized representation of the Hamiltonian known as the configuration interaction (CI) matrix. We construct and query the CI matrix oracle to allow for on-the-fly computation of molecular integrals in a way that is exponentially more efficient than classical numerical methods. Whereas second quantized representations of the wavefunction require $\widetilde{\cal O}(N)$ qubits, where $N$ is the number of single-particle spin-orbitals, the CI matrix representation requires $\widetilde{\cal O}(\eta)$ qubits where $\eta \ll N$ is the number of electrons in the molecule of interest. We show that the gate count of our algorithm scales at most as $\widetilde{\cal O}(\eta^2 N^3 t)$.
Relevance of Fcγ Receptor and Interleukin‐10 Polymorphisms for Meningococcal Disease (2001)

The contribution of individual Fcgamma receptor (FcgammaR) subclasses to meningococcal phagocytosis was studied. In addition, functional FcgammaR polymorphisms were determined in 50 patients with meningococcal disease (MD), in 183 first-degree relatives of MD patients, and in 239 healthy control subjects, to study the association of FcgammaR genotypes with disease. Efficient internalization of opsonized Neisseria meningitidis serogroup B was mediated via multiple FcgammaR subclasses on phagocytes. Accordingly, a low-efficiency combination of FcgammaRIIa-R/R131, FcgammaRIIIa-F/F158, and FcgammaRIIIb-NA2/2 genotypes was increased significantly in relatives of patients with MD, compared with healthy control subjects (P<.05; odds ratio, 2.6; 95% confidence interval, 1.1-6.3). FcgammaRIIa and FcgammaRIIIa genotype distributions differed between patients with sepsis and those with meningitis. Combined genotypes of FcgammaRIIa and interleukin-10 -1082, which was previously reported as being associated with MD outcome, were distributed randomly in control subjects but not in relatives of patients with MD (P<.01). These data provide further evidence for the association of polymorphic genes on chromosome 1 and MD.
A solid‐phase bioreactor with continuous sample deposition for matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry (2011)

We report the development of a solid-phase proteolytic digestion and continuous deposition microfluidic chip platform for low volume fraction collection and off-line matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry. Tryptic peptides were formed in an on-chip bioreactor and continuously deposited onto a MALDI target plate using a motor-driven xyz stage. The bioreactor consisted of a 4 cm × 200 µm × 50 µm microfluidic channel with covalently immobilized trypsin on an array of 50 µm diameter micropost structures with a 50 µm edge-to-edge inter-post spacing. A 50 µm i.d. capillary tube was directly attached to the end of the bioreactor for continuous sample deposition. The MALDI target plate was modified by spin-coating a nitrocellulose solution containing a MALDI matrix on the surface prior to effluent deposition. Protein molecular weight standards were used for evaluating the performance of the digestion and continuous deposition system. Serpentine sample traces 200 µm wide were obtained with a 30 fmol/mm quantity deposition rate and a 3.3 nL/mm volumetric deposition rate.
High-dimensional diffusive growth (2001)

We consider a model of aggregation, both diffusion-limited and ballistic, based on the Cayley tree. Growth is from the leaves of the tree towards the root, leading to non-trivial screening and branch competition effects. The model exhibits a phase transition between ballistic and diffusion-controlled growth, with non-trivial corrections to cluster size at the critical point. Even in the ballistic regime, cluster scaling is controlled by extremal statistics due to the branching structure of the Cayley tree; it is the extremal nature of the fluctuations that enables us to solve the model.

Effects of end-stage renal disease and aluminum hydroxide on temazepam kinetics (1985)

The kinetics of temazepam, 30 mg, were evaluated in 11 patients with end-stage renal disease. Age ranged from 18 to 65 years. On two occasions separated by 1 week, single oral 30 mg doses of temazepam were given once with water (TM) and once with 3600 mg aluminum hydroxide gel (TM + AHG). There were no significant differences in the maximum plasma concentration, the time to reach maximum concentration, or elimination rates between TM and TM + AHG dosing. In approximately half the subjects there were secondary temazepam peak concentrations. In the remaining subjects, temazepam elimination was biphasic, with the terminal t1/2 ranging from 11 to 77 hours. There was a lag time before absorption in all subjects. The percent free temazepam in plasma from dialysis subjects ranged from 4.4% to 8.8% (mean = 5.9%). Compared with literature reports of subjects with normal renal function, the maximum plasma concentration was lower and the percent free temazepam was higher in dialysis subjects. When sedation score was plotted against plasma temazepam concentration, there was clockwise hysteresis consistent with tolerance or adaptation to effects of the drug. Thus aluminum hydroxide gel does not affect temazepam absorption. The clinical significance of the low plasma concentrations and high free temazepam fraction in dialysis subjects is uncertain.
Joint noncoherent demodulation and decoding for the block fading channel: a practical framework for approaching shannon capacity (2003)

The paper contains a systematic investigation of practical coding strategies for noncoherent communication over fading channels, guided by explicit comparisons with information-theoretic benchmarks. Noncoherent reception is interpreted as joint data and channel estimation, assuming that the channel is time varying and a priori unknown. We consider iterative decoding for a serial concatenation of a standard binary outer channel code with an inner modulation code amenable to noncoherent detection. For an information rate of about 1/2 bit per channel use, the proposed scheme, using a quaternary phase-shift keying (QPSK) alphabet, provides performance within 1.6-1.7 dB of Shannon capacity for the block fading channel, and is about 2.5-3 dB superior to standard differential demodulation in conjunction with an outer channel code. We also provide capacity computations for noncoherent communication using standard phase-shift keying (PSK) and quadrature amplitude modulation (QAM) alphabets; comparing these with the capacity with unconstrained input provides guidance as to the choice of constellation as a function of the signal-to-noise ratio. These results imply that QPSK suffices to approach the unconstrained capacity for the relatively low information and fading rates considered in our performance evaluations, but that QAM is superior to PSK for higher information or fading rates, motivating further research into efficient noncoherent coded modulation with QAM alphabets.

All-solid-state diode-pumped cw femtosecond Cr:LiSrAlF6 lasers (1994)

Previously we generated sub-100 fs pulses from a Cr:LiSAF laser using first a dye saturable absorber, 2 and then a MQW saturable absorber, 3 to initiate KLM and achieve self-starting for only 500-mW-absorbed argon ion pump power. Now 670-nm diode-pumping of a truly continuous wave Cr:LiSAF laser, which tuned from 799 to 860 nm with a minimum threshold of 70 mW, has yielded up to 160 mW of output power with 1.5% output coupling. Full duty-cycle active mode-locking was demonstrated using an acousto-optic modulator which yielded~300 ps pulses. 4 An all-solid-state passively mode-locked laser was demonstrated using RPM 5 with the MQW absorber of reference. 3 Stable, self-starting, c.w. mode-locked pulse trains at 250 MHz were observed which were as short as~60 ps duration, as measured using a sampling streak camera. 4 When a standard four prism sequence was incorporated into the cavity, trains of pulses as short as 600 fs were measured using an SHG autocorrelator.
Al2TiO5- New Contributions to its Preparation Via the Sol-Gel Technique (2010)

Fine powders of aluminium titanate (β-Al2TiO5) are conventionally prepared by starting with a mixture of Al- and Ti-alkoxides in the molar ratio of 2:1, hydrolysis and heating the precipitate to temperatures < ∼1300°C. We applied an alternative route and replaced the mixture of alkoxides by the novel heterometallic alkoxide Al2Ti(OiPr)10. X-ray diffraction powder patterns of sintered precipitates reveal no deviation in phase formation and composition from conventionally prepared samples. Precipitates heated at 700 and 1000°C for 14 h show binary phases of TiO2 (anatase, rutile) and TiO2 (rutile) + α-Al2O3 respectively. No metastable Al2O3-phases (σ, δ, θ) are detected. Al2TiO5-formation is observed at temperatures < 1300°C. Shortening of sintering time to 1.5 h exhibits same phases with lower intensities of X-ray peaks.
PhO2 (2017)

Accurately measuring and monitoring patient's blood oxygen level plays a critical role in today's clinical diagnosis and healthcare practices. Existing techniques however either require a dedicated hardware or produce inaccurate measurements. To fill in this gap, we propose a phone-based oxygen level estimation system, called PhO2, using camera and flashlight functions that are readily available on today's off-the-shelf smart phones. Since phone's camera and flashlight are not made for this purpose, utilizing them for oxygen level estimation poses many challenges. We introduce a cost-effective add-on together with a set of algorithms for spatial and spectral optical signal modulation to amplify the optical signal of interest while minimizing noise. A light-based pressure detection algorithm and feedback mechanism are also proposed to mitigate the negative impacts of user's behavior during the measurement. We also derive a non-linear referencing model that allows PhO2 to estimate the oxygen level from color intensity ratios produced by smartphone's camera.
Interleukin-13 (IL-13) induces IL-1 receptor antagonist gene expression and protein synthesis in peripheral blood mononuclear cells: inhibition by an IL-4 mutant protein (1996)

Interleukin-13 (IL-13) belongs to the IL-4 gene family. Like IL-4, IL-13 induces IL-1 receptor antagonist (IL-1Ra) synthesis with no effect on IL-1beta synthesis. We investigated whether IL-13 induces IL-1Ra synthesis via a pathway similar to IL-4. In human peripheral blood mononuclear cells, IL-13 (1 to 100 ng/mL alone induced IL-1Ra synthesis in a dose-dependent manner. A single amino acid mutant form of IL-4 (hIL4.Yl24D) induced IL-1Ra synthesis, acting as a partial agonist. However, hIL-4.Yl24D inhibited IL-1Ra synthesis induced by either IL-4 or IL-13. IL-13 alone induced accumulation of IL-1Ra mRNA. Furthermore, IL-13 reduced steady- state levels for IL-1beta mRNA but enhanced those for IL-1Ra mRNA in cells stimulated with lipopolysaccharide (LPS) or IL-1alpha. Accordingly, IL-13 suppressed IL-1beta synthesis but enhanced IL-1Ra synthesis in these cells. IL-13 reduced the stability of IL-1beta mRNA (2.9 v 1.7 hours) but failed to modify the stability of IL-1Ra mRNA (2.7 v 2.5 hours). Moreover, IL-13 induced transcriptional activation of the IL-1Ra gene, but reduced IL-1beta gene transcription. Our results suggest that the commonality between IL-13 and IL-4 in inducing IL-1Ra synthesis results from the engagement of a subunit common to both receptors.
Measurement of energy decay in superconducting qubits from nonequilibrium quasiparticles (2011)

Quasiparticles are an important decoherence mechanism in superconducting qubits, and can be described with a complex admittance that is a generalization of the Mattis-Bardeen theory. By injecting nonequilibrium quasiparticles with a tunnel junction, we verify qualitatively the expected change of the decay rate and transition frequency in a phase qubit. With their relative change in agreement to within 4 % of prediction, the theory can be reliably used to infer quasiparticle density. We describe how settling of the decay rate may allow determination of whether qubit energy relaxation is limited by nonequilibrium quasiparticles.
<title>Passive tunable fiber Fabry-Perot filters for transparent optical networks</title> (1993)

Maestro-U: Leveraging Joint Speech-Text Representation Learning for Zero Supervised Speech ASR (2023)

Training state-of-the-art Automated Speech Recognition (ASR) models typically requires a substantial amount of transcribed speech. In this work, we demonstrate that a modality-matched joint speech and text model introduced in [1] can be leveraged to train a massively multilingual ASR model without any supervised (manually transcribed) speech for some languages. This paper explores the use of jointly learnt speech and text representations in a massively multilingual, zero supervised speech, real-world setting to expand the set of languages covered by ASR with only unlabeled speech and text in the target languages. Using the FLEURS dataset, we define the task to cover 102 languages, where transcribed speech is available in 52 of these languages and can be used to improve end-to-end ASR quality on the remaining 50. First, we show that by combining speech representations with byte-level text representations and use of language embeddings, we can dramatically reduce the Character Error Rate (CER) on languages with no supervised speech from 64.8% to 30.8%, a relative reduction of 53%. Second, using a subset of South Asian languages we show that Maestro-U can promote knowledge transfer from languages with supervised speech even when there is limited to no graphemic overlap. Overall, Maestro-U closes the gap to oracle performance by 68.5% relative and reduces the CER of 19 languages below 15%.
Improving Cross-domain Authentication overWireless Local Area Networks (2006)

As mobile users cross the border of two adjacent domains with on-going sessions, their re-authentication causes a significant impact on inter-domain handoff latency as it requires remote contact with the authentication server across domains, making it difficult to employ current authentication protocols. This paper focuses on the cross-domain authentication over wireless local area networks (WLANs) that minimizes the need for remote access. We analyze the security requirements suggested by the IEEE 802.11i authentication standard, and consider additional requirements to help reduce the authentication latency without compromising the level of security. We propose an enhanced protocol called the Mobility-adjusted Authentication Protocol (MAP) that performs mutual authentication and hierarchical key derivation with minimal handshakes, relying on symmetric cryptographic functions. We also present security context nodes (SCNs) that handle security contexts in conjunction with MAP, which allows for avoiding continuous remote contact with the home authentication server. In contrast to Kerberos which favors inter-realm authentication, MAP achieves a 26% reduction of authentication latency without degrading the level of security.
Chemical Mechanical Planarization of Copper: Role of Oxidants and Inhibitors (2004)

Investigations were carried out to understand the effect of hydrogen peroxide as an oxidant and benzotriazole (BTA) as an inhibitor on the chemical mechanical planarization (CMP) of copper. Cu-CMP was studied using electrochemistry and removal rate measurements in solutions containing the oxidizer and the inhibitor. In the presence of 0.1 M glycine, the copper removal rate was high in the solution containing 5% H(2)O(2) at pH 2 because of a Cu-glycine complexation reaction. The dissolution rate of Cu increased due to the formation of the highly soluble Cu-glycine complex in the presence of hydrogen peroxide. Addition of 0.01 M BTA in the solution containing 0.1 M glycine and 5% H(2)O(2) at pH 2 exhibited a reduction in the Cu removal rate by the formation of a Cu-BTA complex on the surface of copper that inhibits the dissolution. X-ray photoelectron spectroscopy and secondary-ion mass spectroscopy investigations revealed the formation of a Cu-glycine complex, which aided the understanding of the mechanism of Cu-oxidant-inhibitor interaction during polishing.
