A matrix converter excited doubly-fed induction machine as a wind power generator (1998)

A grid-connected wind-power generation scheme using a doubly-fed induction generator (DFIG) in conjunction with a direct AC-AC matrix converter is proposed. The analysis employs a stator-flux vector-control algorithm and a space vector modulated matrix converter to control the generator rotor current. The system enables optimal speed tracking for maximum energy capture from the wind and high performance active and reactive power regulation. The paper discusses the operating principles of this power generation scheme. The matrix converter-based rotor current control method is described. Simulation studies of the proposed power generation system were carried out. Results obtained are presented illustrating good control performance of the system.
Ascertaining the morphological components of Tamil language using unsupervised approach (2016)

The learning of morphological components in a natural language by means of segmentation of words to identify the prime chores of stems and affixes lead to effective morphological analysis. Morphological segmentation is an important step in the analysis of natural languages to identify its intricate properties. Remarkable approaches been used in order to construct an effective morphological segmentation framework to study the highly agglutinative Tamil language. This paper focus on unsupervised means of segmenting Tamil lexicons by using a novel algorithm across various parameters. The proposed work shows a promising result in favour to the identification of morphemes with their suffixes.
Output power maximization for double layer heating of impeller and container of mixer (2017)

In this paper, the fast heating up impeller and container directly by induction heating is proposed. Simultaneous heating of the impeller and the container leads to the homogeneous and rapid heating for the chemical reaction. To show the feasibility of proposed method, the induction heating of the double layer of the stainless steel plates are investigated. Experimental results show the good feasibility of the simultaneous heating. To know the input power to the impeller, the equivalent coil is used for the measurement. The simple equivalent circuit is proposed and the calculation from it shows good coincidence to the dependency to the SUS plate thickness. Both the experimental results and the calculated results show that there is the optimum thickness of the impeller to maximize the output power. The thickness of the middle plate also affects the performance of the impeller heating. The experimental results show that the thinner is better. Finally, realistic heating experiments show the good temperature rise.
Calcium‐Dependent Localization of S100A6 in Pulmonary Microvascular Endothelial Cells (2020)

During inflammation, mediators increase calcium influx into endothelial cells through store‐operated calcium entry (SOCE) channels. Increasing calcium influx through the SOCE current I SOC promotes endothelial barrier disruption through the formation of inter‐endothelial cell gaps. Inter‐endothelial cell gap formation leads to increased permeability. Identifying mechanisms of I SOC inhibition may aid in the development of therapeutic strategies against endothelial permeability‐associated vascular inflammation. Our studies indicate FK506‐binding protein 51 (FKBP51), in conjunction with protein phosphatase 5 (PPP5C), inhibit I SOC and calcium entry‐induced inter‐endothelial cell gap formation. Further, we determined that the calcium‐binding protein S100A6 is necessary for the PPP5C‐FKBP51‐mediated inhibition of I SOC in pulmonary microvascular endothelial cells (PMVECs). In PMVECs, S100A6 interacts with the ISOC channel in a calcium‐dependent manner, i.e. , following an increase in cytosolic calcium. However, we do not know whether calcium entry specifically through the ISOC channel or through other SOCE channels that provides the calcium source to promote S100A6 interaction with the ISOC channel. Methods PMVECs were used for co‐precipitation and immunocytochemistry‐based studies. When cells are treated with rolipram (R) plus thapsigargin (Tg), ISOC and other SOCE channels are activated. However, when cells are treated with Tg alone, ISOC is not activated, but other SOCE channels are activated. The TRPC4 subunit of the ISOC channel was immunoprecipitated and probed for co‐precipitation of S100A6. Results Following R/Tg treatment, robust co‐precipitation of S100A6 with TRPC4 was observed, whereas following Tg alone only minor co‐precipitation was seen. Immunocytochemistry revealed that in untreated cells S100A6 localization is principally cytosolic. Following R/Tg treatment, but not Tg alone, a distinct membrane‐delimited pool of S100A6 was observed, particularly at sites of cell‐cell contact. Membrane localization was confirmed by co‐localization with wheat germ agglutinin (WGA). Conclusion Overall, our data reveal that calcium entry specifically through the ISOC channel is an important determinant of S100A6 translocation to the plasma membrane promoting interaction of S100A6 with the ISOC channel.

Integrated fiber optic probe for dynamic light scattering (1993)

An integrated fiber optic probe, comprising a monomode optical fiber fusion spliced to a short length of a graded-index multimode fiber, is fabricated for use as a coherent receiver in dynamic light scattering. The multimode fiber is cleaved to provide a gradient-index fiber lens with a focal length of 125 µm and an ƒ-number close to unity. An integrated fiber receiver is used to measure the intensity-intensity autocorrelation data from a 0.05% by weight concentration of an aqueous suspension of polystyrene latex spheres. Analysis of 100 independent data sets indicates that the particle size can be recovered with an accuracy of ±1%.
Impact of model-based fracturing on e-beam proximity effect correction methodology (2010)

The current e-beam proximity effect correction equations are reviewed in the context of model-based fracturing where shots can overlap and the dose of each shot can be set individually. A new set of equations is proposed and verified. The formulation is shown to lift some restrictions imposed by the older formulation such as the minimum shot size dimension and the type of model used to describe forward scattering effects. The new model does not require the function to be Gaussian or the operation with the dose map to be a convolution. We also demonstrate that using current mask writing equipment, the correction of overlapping shots can be performed accurately if the correction of each shot is performed taking into account all the shots. Verification is done using two different approaches. The first solution consists of using directly the modified proximity effect equations to calculate the dose for each shot. The second solution makes the correction a part of the model-based fracturing process. The results obtained for both approaches are identical showing that the theory and the implementations are correct.
Fusing MFCC and LPC Features Using 1D Triplet CNN for Speaker Recognition in Severely Degraded Audio Signals (2019)

Speaker recognition algorithms are negatively impacted by the quality of the input speech signal. In this work, we approach the problem of speaker recognition from severely degraded audio data by judiciously combining two commonly used features: Mel Frequency Cepstral Coefficients (MFCC) and Linear Predictive Coding (LPC). Our hypothesis rests on the observation that MFCC and LPC capture two distinct aspects of speech, viz., speech perception and speech production. A carefully crafted 1D Triplet Convolutional Neural Network (1D-Triplet-CNN) is used to combine these two features in a novel manner, thereby enhancing the performance of speaker recognition in challenging scenarios. Extensive evaluation on multiple datasets, different types of audio degradations, multi-lingual speech, varying length of audio samples, etc. convey the efficacy of the proposed approach over existing speaker recognition methods, including those based on iVector and xVector.
An integrated network management framework for Internet access service using ATM over ADSL technology (2003)

We propose an integrated network management framework for Internet access service using ATM over ADSL technology. There are two distinct networks of ATM and Internet. Most of the routers in the Internet are connected with WDM. The network access server (NAS) in the Internet provides the Internet access service for the ATM over ADSL subscriber. The ATM network takes the roles of backbone network for the pure ATM PVC and SVC services and the access network for the ATM over ADSL service. In order to define the generic network model that can be commonly applicable for the backbone network for pure ATM service and the access network for ATM over ADSL service taking into account the scalability, we suggest two fragments of the topological fragment and connectivity fragment to maximize the scalability in accordance with the ITU-T G805 layering and partitioning concepts and the RM-ODP information viewpoint. In addition, we propose the distributed computational model of the ATM over ADSL network management system using the RM-ODP computational viewpoint and TMN functional decomposition of FCAPS taking into account the functional distribution and the modularity. Lastly, we describe the scenario for providing the Internet access service.
Sharing Features among Dynamical Systems with Beta Processes (2009)

We propose a Bayesian nonparametric approach to the problem of modeling related time series. Using a beta process prior, our approach is based on the discovery of a set of latent dynamical behaviors that are shared among multiple time series. The size of the set and the sharing pattern are both inferred from data. We develop an efficient Markov chain Monte Carlo inference method that is based on the Indian buffet process representation of the predictive distribution of the beta process. In particular, our approach uses the sum-product algorithm to efficiently compute Metropolis-Hastings acceptance probabilities, and explores new dynamical behaviors via birth/death proposals. We validate our sampling algorithm using several synthetic datasets, and also demonstrate promising results on unsupervised segmentation of visual motion capture data. 1
Measurement of Hypoxanthine in Fish as a Method of Assessing Freshness (1964)

SUMMARY The hypoxanthine contents of fresh fillets taken from three species of fish in Pacific Northwest waters were found to he almost zero, and increased at a fairly uniform rate during the first 8‐10 days of storage in melting ice. The hypoxanthine content reached maximum values in about 8‐10 days. Total nucleotides reached a minimum in about 6‐8 days. Fillets stored at −20°F showed practically no change in hypoxanthine content during four, months of storage. Hypoxanthine can be rapidly measured and the data can be used to judge the length of time fish has been held in storage.

Symmetries of single-slice multiple-pinhole tomographs (2002)

The singular-value decomposition (SVD) of an imaging system can be used to characterize the system. For example, because the SVD can be used to characterize the null space and range space of a system, it can be used to investigate the nature of the information a system measures and that which it does not measure. As this is the case, the SVDs of various tomographic systems have been specified and used to characterize some systems; however, specification of the SVDs of multiple-pinhole systems has not been done. We present results related to development of such a specification. A matrix operator that models a single-slice multiple-pinhole tomograph is generated via simulation, the SVD of the operator numerically obtained, and the symmetries of the system identified and correlated with symmetries of the singular vectors. Specifically, because the symmetries of the system are consistent with the structures of the dihedral group of order eight, the symmetries of the singular vectors are correlated with the irreducible representations of the dihedral group, D/sub 4/.
Studies on Human Sexual Development. I. Fetal Gonadal and Adrenal Sex Steroids1 (1973)

Testosterone and estradiol concentrations were measured by isotope-displacement assays in the gonads and adrenals of 54 human fetuses (33 male, 21 female) delivered by hysterotomy. Results were correlated with crownrump (CR) length which ranged from 5 to 24 cm, corresponding to 10–25 weeks fetal age. Testosterone concentration averaged 1400 pg/mg in the testes but was negligible (<90 pg/mg) in the ovaries and in the adrenals of both sexes. Testosterone was found in appreciable amounts in the testes from the youngest specimens, reached a peak at 7–10 cm CR-length and declined by 13–14 cm CR-length. Little or no estradiol was detected in fetal testes, ovaries and adrenals and there were no sex differences in these levels. These data provide evidence that human fetal testicular tissue accumulates testosterone in a pattern suggesting higher androgen production at the time of male genital differentiation.
Influence of silver-nanoparticle layer in a chiral sculptured thin film for surface-multiplasmonic sensing (2015)

Multiple surface-plasmon-polariton (SPP) waves can be guided by the interface of a metal and a chiral sculptured thin film (STF). It is possible to embed within the chiral STF a layer of silver nanoparticles as sites to bind recognition molecules for sensing analytes of a certain kind. Chiral STFs were deposited on aluminum thin films. 5-nm-thick layers of silver nanoparticles were deposited in the chiral STF at different depths in different samples. The samples were then deployed in the Turbadar–Kretschmann–Raether configuration to observe the effects the silver-nanoparticle layer had on the multiple SPP-wave modes in relation to the depth. We concluded that the silver-nanoparticle layer tends to shift the angular locations of the SPP-wave modes but does not necessarily affect the location of the SPP-wave modes to an extent that would render the data uninterpretable.
Operation of the NuMI Beam Monitoring System (2006)

The NuMI (Neutrinos at the Main Injector) facility produces an intense neutrino beam for experiments. The NuMI Beam Monitoring system consists of four arrays of ion chambers that measure the intensity and distribution of the remnant hadron and tertiary muon beams produced in association with the neutrinos. The ion chambers operate in an environment of high particle fluxes and high radiation.

Secondary Neck Lift and the Importance of Midline Platysmaplasty: Review of 101 Cases (2016)

Background: The authors believe that open access to the submental region, platysmaplasty, and wide skin undermining provide the most long-lasting results in neck rejuvenation, and sought to evaluate this hypothesis by reviewing their neck-lift patients. Methods: The authors performed a retrospective chart review of their experience with neck-lift procedures and patients who underwent a secondary procedure. Patient age, sex, initial technique, visible neck deformities, and reasons for revision were assessed. Photographs were used to assess the features of persistent or recurrent neck-lift deformity and techniques to correct them. Results: Of 1089 neck lifts reviewed, 101 patients underwent secondary or revision procedures (approximately 10 percent of total). The average patient age was 57.4 years, 95 percent were women, and secondary procedures were performed 10.3 years after the first procedure. Seventy percent of the revisions were of the authors’ own primary neck lifts, and all of these after 10 years. The most common aesthetic deformities—recurrent platysmal bands (87 percent), persistent/recurrent jowling (48 percent), fat malposition/irregularities (10 percent), and vertical band deformity (8 percent)—were most often corrected with open platysmaplasty and medial or lateral plication and skin redraping. All patients had their submental region opened in the secondary procedure. All secondary operations were performed at least 10 years after primary surgery. Conclusions: The authors believe their technique of open submental neck access and platysmal approximation in patients with medial bands provides long-lasting results. The authors use precise preoperative evaluation, recontouring of neck fat irregularities, opening of the submental region with platysmaplasty, drains, and strict hemostasis. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
Radio-over-Fiber System with 1-Bit Outphasing Modulation for 5G/6G Indoor Wireless Communication (2022)

We propose a radio-over-fiber (RoF) system with 1-bit outphasing modulation. The proposed RoF system does not require a power-hungry digital-to-analog converter in access points and relaxes the operation speed of optical transceivers to reduce device cost. We introduce two configurations to enable 1-bit outphasing modulation in our system; mixed-signal and all-digital configurations. In the mixed-signal configuration, the effects of harmonics and phase/amplitude mismatch on the adjacent channel leakage ratio (ACLR) were analyzed through simulation, and wideband transmission with a signal bandwidth of 400 MHz was experimentally verified, complying with the 3rd Generation Partnership Project (3GPP) standard for millimeter-wave band. Moreover, wide-band transmission with a signal bandwidth of 1 GHz was also experimentally verified for beyond-5G and 6G. The all-digital configuration can be implemented in a standard digital design flow. This configuration was also verified to comply with the 3GPP standard by properly selecting the intermediate and sampling frequencies to mitigate the effects of folded harmonics and quantization noise. Finally, the proposed RoF system with both configurations has been shown to have a higher bandwidth efficiency compared with other systems complying with the 3GPP standard for the ACLR. Therefore, the proposed RoF system provides a cost-effective in-building wireless solution for 5G and 6G mobile network systems.
Smamite, Ca2Sb(OH)(4)[H(AsO4)(2)]center dot 6H(2)O, a new mineral and a possible sink for Sb during weathering of fahlore (2020)

Smamite, Ca2Sb(OH)(4)[H(AsO4)(2)]center dot 6H(2)O, is a new mineral species from the Giftgrube mine, Rauenthal, Sainte-Marie-Aux-Mines ore-district, Haut-Rhin department, France. It is a supergene mineral found in quartz-carbonate gangue with disseminated to massive tennantite-tetrahedrite series minerals, native arsenic, Ni-Co arsenides, and supergene minerals picropharmacolite, fluckite, and pharmacolite. Smamite occurs as lenticular crystals growing in aggregates up to 0.5 mm across. The new mineral is whitish to colorless, transparent with vitreous luster and white streak; non-fluorescent under UV radiation. The Mohs hardness is3(1/2); the tenacity is brittle, the fracture is curved, and there is no apparent cleavage. The measured density is 2.72(3) g/cm(3); the calculated density is 2.709 g/cm(3) for the ideal formula. The mineral is insoluble in H2O and quickly soluble in dilute (10%) HCl at room temperature. Optically, smamite is biaxial (-), alpha = 1.556(1), beta = 1.581(1), gamma = 1.588(1) (white light). The 2V (meas) = 54(1)degrees; 2V (calc) = 55.1 degrees. The dispersion is weak, r > gamma. Smamite is non-pleochroic. Electron microprobe analyses provided the empirical formula Ca-2 center dot 03Sb(0.97)(OH)(4)[H-1.10(As1.99Si0.01O4)(2)]center dot 6H2O. Smamite is triclinic, P (1) over bar, alpha = 5.8207(4), b = 8.0959(6), c = 8.21296(6) angstrom, alpha = 95.8343(7)degrees, beta = 110.762(8)degrees, gamma = 104.012(7)degrees, V = 402.57(5) angstrom 3, and Z = 1. The structure (Robs = 0.027 for 1518 I>3sI reflections) is based upon {Ca-2(H2O)(6)Sb(OH)(4)[H(AsO4)(2)]} infinite chains consisting of edge-sharing dimers of Ca(H2O)(3)O-2(OH)(2) polyhedra that share edges with Sb(OH)(4)O-2 octahedra; adjacent chains are linked by H-bonds, including one strong, symmetrical H-bond with an O-H bond-length of similar to 1.23 angstrom. The name smamite is based on the acronym of the Sainte-Marie-aux-Mines district.
Impact of Cannabis Use on Long-Term Remission in Bipolar I and Schizoaffective Disorder (2015)

Cannabis use negatively affects the long-term clinical outcome in patients with bipolar spectrum disorders. A comprehensive assessment and integrated management of cannabis use are required to achieve better treatment outcomes for bipolar spectrum disorders.
Quadrature multiplexed BOC modulation for interoperable GNSS signals (2010)

A modulation for global navigation satellite systems (GNSS) signals called quadrature multiplexed BOC (QMBOC), with the corresponding correlation receiver and constant envelope multiplexing schemes, is presented. Placing the narrowband BOC component and the wideband BOC component in phase quadrature, QMBOC modulation remains an MBOC spectral constraint, which eliminates the cross-term in the autocorrelation function. It provides a new modulation option for interoperable GNSS signals.
Effect of Formulation and Processing Variables on the Granulation Kinetics of Hot Melt Granulation (HMG) Process (2007)

The objective of the study was to evaluate the effect of formulation factors, such as type of drug and particulate properties of a drug, and processing variables, i.e. jacket temperature, impeller speed, and scale, on granulation kinetics the of hot-melt granulation (HMG) process. Two model active pharmaceutical ingredients (API) Ro-A and indomethacin were selected for this evaluation using poloxamer 188 as a meltable binder. The effect of solid-state properties of API was investigated for Ro-A, whereas the binder properties were maintained constant. General factorial design was used to investigate the effect of independent process variables, impeller speed and jacket temperature using impeller motor power consumption as response variable. Consistent granulation could be developed for Ro-A by optimizing the binder level and impeller speed, however, the addition of third excipient was necessary for indomethacin. The granulation rate was related to the bulk density and the surface area of the drug. The jacket temperature affected overall granulation time but had no significant effect on the granulation kinetics, suggesting that faster heating rate is desirable for optimal productivity. A significant increase in the granulation rate was observed with increase in impeller speed. The effect of impeller speed was further confirmed at 5 L and 25 L scale. From the formulation prospective, the critical factors were the level of binder, inherent binding properties of the API, the solid-state properties of API and binder. From processing perspectives, the impeller speed had a significant effect on the granulation kinetics.
