Uplink control channel for 5G new RAT (2017)

In this paper, designs for the New Radio (NR) physical uplink control channel (NR PUCCH) spanning 1 orthogonal frequency division multiplexing (OFDM) symbol duration (short-PUCCH) is investigated. Two short-PUCCH formats i.e., Format A, in which demodulation reference signal (DMRS) and uplink control information (UCI) are FDMed, and Format B, in which DMRS and UCI are TDMed, are proposed and evaluated by computer simulation. For Format A, various DMRS overheads can be realized by adjusting the numbers of DMRS subcarriers and that of UCI subcarriers for the given 1 OFDM symbol. For Format B, we assume no FDM between DMRS and UCI, so that discrete Fourier transform (DFT)-spread OFDM (DFT-s-OFDM) waveform is applicable; in order to adjust DMRS overhead, we locate more than one OFDM symbols within the given 1 OFDM symbol duration by using higher subcarrier spacing (SCS) for the short-PUCCH with Format B. The link-level evaluation results and link-budget analysis show that Format A offers better link-level performance than Format B, while better link-budget performance is achieved by Format B, with taking into account the peak-to-average power ratio (PAPR) power back-off margin.
Non-native speech conversion with consistency-aware recursive network and generative adversarial network (2017)

This paper deals with the problem of automatically correcting the pronunciation of non-native speakers. Since the pronunciation characteristics of non-native speakers depend heavily on the context (such as words), conversion rules for correcting pronunciation should be learned from a sequence of features rather than a single-frame feature. For the online conversion of local sequences of features, we construct a neural network (NN) that takes a sequence of features as an input/output, generates a sequence of features in a segment-by- segment fashion and guarantees the consistency of the generated features within overlapped segments. Futhermore, we apply a recently proposed generative adversarial network (GAN)-based postfilter to the generated feature sequence with the aim of synthesizing natural-sounding speech. Through subjective and quantitative evaluations, we confirmed the superiority of our proposed method over a conventional NN approach in terms of conversion quality.
Effect of nonlinearity on lesion formation for high-intensity focused ultrasound (HIFU) exposures (2004)

This study examined the effects of nonlinear propagation phenomena on two types of HIFU transducers (5 MHz) being used for thermal treatments of disease. The first transducer is a 5-element annular array. The second is a transducer with a 5-strip electrode; its multilobed focused beam is designed to efficiently produce broad, paddle-shaped lesions. The beam patterns of these transducers were computed using a variety of excitation patterns for electronic focusing of the annular array and variation of lesion size for the strip-electrode transducer. A range of intensities was studied to determine how nonlinear propagation affects the beam shape, constituent frequency content, grating lobes, etc. These 3D computations used a finite-amplitude beam propagation model that combined the angular spectrum method and Burger’s equation to compute the diffraction and nonlinear effects, respectively. Computed beam patterns were compared with hydrophone measurements for each transducer. The linear and nonlinear beam patterns were used to compute the absorbed thermal dose, and the bioheat equation was evaluated to calculate 3D temperature rises and geometry of induced lesions. Computed lesion sizes and shapes were compared to in vitro lesions created by each HIFU transducer. [Work supported by NCI and NHLBI Grant 5R01 CA84588.]
Absorptivity of SiF4 at 1027 cm−1 for High Continuous-Wave Laser Power (1996)

Silicon tetrafluoride (SiF4) and sulfur hexafluoride (SF6) are widely used as sensitizing agents in photochemical experiments in the infrared region of the spectrum. These experiments include chemical vapor deposition, powder formation (for a review see Ref. 1), and kinetics. The energy of the Si-F bond is 610 kJ mol-1, whereas that of the corresponding S-F bond is 300 kJ mol-1. Therefore, SiF4 is expected to be a more versatile sensitizing agent than SF6, since the relatively high Si-F bond energy allows for greater radiative energy input and higher effective reaction temperatures. The high effective temperatures attained with the use of SiF4 (or SF6) necessitate the study of the absorptivities of these materials, since that quantity is known to be temperature dependent. Unfortunately, although some experimental results have been reported for SF6, such data are not generally available for SiF4. Moreover, in the case of laser-excited experiments, there is the potential for photochemical bleaching. Again, such data have been obtained for SF6, but only a limited amount of information is available for SiF4. In this study, we report on the absorptivity as a function of sample pressure (temperature) and as a function the continuous-wave (cw) laser power for conditions typically employed in sensitized infrared-driven chemical processes. It may be readily observed from the presented data that the absorptivity decreases with increasing laser power and that a limiting temperature is reached for increasing sample pressure at a constant laser power.
GBParsy: A GenBank flatfile parser library with high speed (2008)

GBParsy is estimated to extract annotated information from almost 100 Mb of a GenBank flatfile for chromosomal sequence information within a second. Thus, it should be used for a variety of applications such as on-time visualization of a genome at a web site.
Lifetime measurements in42Ca (populated in28Si(16O,2p)) (1975)

High spin states in 42Ca between 4.1 and 7.4 MeV excitation energy were populated in the reaction 28Si(16O,2p) at 36.5-50 MeV beam energy. Using the recoil distance Doppler shift method, their lifetimes and upper limits of their spins were determined. Neither strongly enhanced E2 transitions nor rotational-like behaviour of these states were observed.

Glycan Residues Balance Analysis - GReBA: A novel model for the N-linked glycosylation of IgG produced by CHO cells (2019)

The structure of N-linked glycosylation is a very important quality attribute for therapeutic monoclonal antibodies. Different carbon sources in cell culture media, such as mannose and galactose, have been reported to have different influences on the glycosylation patterns. Accurate prediction and control of the glycosylation profile are important for the process development of mammalian cell cultures. In this study, a mathematical model, that we named Glycan Residues Balance Analysis (GReBA), was developed based on the concept of Elementary Flux Mode (EFM), and used to predict the glycosylation profile for steady state cell cultures. Experiments were carried out in pseudo-perfusion cultivation of antibody producing Chinese Hamster Ovary (CHO) cells with various concentrations and combinations of glucose, mannose and galactose. Cultivation of CHO cells with mannose or the combinations of mannose and galactose resulted in decreased lactate and ammonium production, and more matured glycosylation patterns compared to the cultures with glucose. Furthermore, the growth rate and IgG productivity were similar in all the conditions. When the cells were cultured with galactose alone, lactate was fed as well to be used as complementary carbon source, leading to cell growth rate and IgG productivity comparable to feeding the other sugars. The data of the glycoprofiles were used for training the model, and then to simulate the glycosylation changes with varying the concentrations of mannose and galactose. In this study we showed that the GReBA model had a good predictive capacity of the N-linked glycosylation. The GReBA can be used as a guidance for development of glycoprotein cultivation processes.
Plasmonic Tipless Pyramid Arrays for Cell Poration (2015)

Improving the efficiency, cell survival, and throughput of methods to modify and control the genetic expression of cells is of great benefit to biology and medicine. We investigate, both computationally and experimentally, a nanostructured substrate made of tipless pyramids for plasmonic-induced transfection. By optimizing the geometrical parameters for an excitation wavelength of 800 nm, we demonstrate a 100-fold intensity enhancement of the electric near field at the cell-substrate contact area, while the low absorption typical for gold is maintained. We demonstrate that such a substrate can induce transient poration of cells by a purely optically induced process.
An Electrodynamic Wireless Power Receiver ‘Chip’ for Wearables and Bio-implants (2020)

This paper presents the design, fabrication and experimental characterization of a chip-sized wireless power receiver for low-frequency electrodynamic wireless power transmission (EWPT). Utilizing a laser micro-machined meandering suspension, one NdFeB magnet, and two PZT-SA piezoelectric patches, this 0.08 cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> micro-receiver operates at its torsion mode mechanical resonance of 724 Hz. The device generates 360 μW average power (4.2 mWcm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-3</sup> power density) at 1 cm distance from a transmitter coil operating at 724 Hz and safely within allowable human exposure limits of 2 mTrms field. Compared to a previously reported macro-scale prototype, this volume-efficient micro-receiver is 31x smaller and offers 3.2x higher power density within a low-profile, compact footprint for wirelessly charging wearable and bio-implantable devices.
Aneuploidy does not explain the difference in outcomes observed between Asian and Caucasian patients undergoing in vitro fertilization (2015)

To understand whether reduced pregnancy and live birth rates for Asian patients undergoing in vitro fertilization (IVF) could be explained by discrepant rates of aneuploid embryos. A retrospective cohort study of all autologous and donor IVF cycles utilizing pre-implantation genetic screening (PGS) at a single infertility clinic from January 2012 to December 2013. After controlling for maternal age, there was no difference in aneuploidy rates of Caucasian patients compared to Asian patients'. A trend was discerned that embryos of Caucasians form blastocysts more frequently than those of Asian patients, reaching significance for patients aged 25 to 30 and 40 to 45, but there was no difference in the likelihood of having at least one euploid blastocyst to transfer in any age group. While there may be a slight difference in blastocyst formation rates, there is no difference in aneuploidy or euploid blastocyst transfer rates between Asian and Caucasian patients that would explain the discrepancy in IVF outcomes observed between these patient populations. Possible ethnicity specific differences in non-ploidy related embryo viability and endometrial receptivity should be investigated as potential etiologies for this observation.
Resolving fundamental limits of adhesive bonding in microfabrication. (2004)

As electronic and optical components reach the micro- and nanoscales, efficient assembly and packaging require the use of adhesive bonds. This work focuses on resolving several fundamental issues in the transition from macro- to micro- to nanobonding. A primary issue is that, as bondline thicknesses decrease, knowledge of the stability and dewetting dynamics of thin adhesive films is important to obtain robust, void-free adhesive bonds. While researchers have studied dewetting dynamics of thin films of model, non-polar polymers, little experimental work has been done regarding dewetting dynamics of thin adhesive films, which exhibit much more complex behaviors. In this work, the areas of dispensing small volumes of viscous materials, capillary fluid flow, surface energetics, and wetting have all been investigated. By resolving these adhesive-bonding issues, we are allowing significantly smaller devices to be designed and fabricated. Simultaneously, we are increasing the manufacturability and reliability of these devices.
A View from the Inside:  Complexity in the Atomic Scale Ordering of Supported Metal Nanoparticles (2001)

In this report, we describe the use of several analytical techniques, including X-ray absorption spectroscopy (XAS), electron microscopy, and electron diffraction, as tools for characterizing the structural dynamics of supported Pt nanoscale particles. We examined several carbon-supported samples. Electron microscopy shows that the particles in these samples (S1−S3) have average particle diameters of roughly 20, 40, and 60 Å respectively, while electron microdiffraction data for these particles provided evidence of long-ranged ordering in the form of face centered cubic structures. This study highlights the use of advanced synchrotron X-ray absorption spectroscopies (XAS), in particular extended X-ray absorption fine structure (EXAFS) and X-ray absorption near-edge structure (XANES), as powerful tools for studying the structural habits and dynamics of these prototypical nanoscale materials. Using state-of-the-art methods of measurement and computational modeling, we demonstrate that it is possible to develop a detailed understanding of the shape and morphology of the nanoscale clusters. We use these techniques to provide information about the nature of their surface texturing, establishing that they preferentially adopt oblate ("hemispherical") cuboctahedra cluster shapes truncated along the [111] basal plane. We further describe the use of temperature-dependent EXAFS measurements to investigate the nature of bond relaxation phenomenon occurring within the small metallic nanoparticles. To evaluate these complex structural behaviors, the disorder parameters are calculated from temperature-dependent EXAFS data and then subsequently compared to simple molecular graphics simulations of mechanisms involving either full cluster or surface relaxations. The average bond length and static disorder obtained by experiment appear to best fit a model involving dominant contributions made by surface atom bond relaxation.

This DOI is not currently attached to any metadata records. DOIs can’t actually ever be deleted (they’re persistent), but sometimes our members create DOIs in error. We do have a process to approximate deletion which we follow only in rare cases where the DOI has been genuinely created in error, and most crucially, if the DOI has never been published anywhere online or in print and never otherwise distributed to or communicated with anyone (authors, readers, reviewers, etc.
DEEP LEARNING APPROACHES FOR ANOMALIES DETECTION OF BLADDER CT CONTOURS IN PROSTATE CANCER PATIENTS (2022)

In radiation therapy, poor contour delineations of Region of Interests (ROI) may result in incorrect radiation dosing and increase the chance of radiation-induced toxicities. To better recognize these contours, we used a feature fusion-based 3-dimensional convolution neural network (3D-CNN), multi-view convolution neural network (MV-CNN), and 3D point cloud to retrospectively detect abnormal bladder contours among prostate cancer patients. We defined three patterns of abnormal bladder contours: (1) discontinuities: missing slices and disparate volumes, (2) surface aberrations: extended or contracted slices, (3) small volume: bladder volume [Formula: see text][Formula: see text]ml. We created virtual samples for discontinuities and surface aberrations by randomly adding pixel to one or more slices outside the original contours and randomly extending or shrinking one or more slices. For both 3D-CNN and MV-CNN methods, we utilized the Local Binary Pattern (LBP) and Canny operators for feature extraction and compared several feature fusion-based approaches, including Original image + LBP processed image, Original image + Canny processed image, Original image + LBP processed image + Canny processed image. For the 3D point cloud, we applied the 3D point cloud segmentation method (Rand LA-Net) and the 3D point cloud classifying method (DGCNN). We had 344 samples available (219 real contours and 125 virtual contours) altogether. All the algorithms were trained on 200 bladder contours, validated on 100 bladders, then tested on 44 real annotated contours. Among all the approaches, the “Original + LBP”-based MV-CNN model achieved the highest accuracy: 100% for predicting discontinuity and small volume, 91.3% for predicting normal contours, and 90.9% for predicting surface aberrations. MV-CNN performed more accurately and efficiently across all the feature fusion methods. In particular, “Original + LBP”-based MV-CNN achieved the highest test accuracy. Our tools can detect anomalies of bladder contours in clinical settings and may improve the process of contour quality assurance (QA).
Structural studies of the engrailed homeodomain (1994)

The structure of the Drosophila engrailed homeodomain has been solved by molecular replacement and refined to an R-factor of 19.7% at a resolution of 2.1 A. This structure offers a high-resolution view of an important family of DNA-binding proteins and allows comparison to the structure of the same protein bound to DNA. The most significant difference between the current structure and that of the 2.8-A engrailed-DNA complex is the close packing of an extended strand against the rest of the protein in the unbound protein. Structural features of the protein not previously noted include a "herringbone" packing of 4 aromatic residues in the core of the protein and an extensive network of salt bridges that covers much of the helix 1-helix 2 surface. Other features that may play a role in stabilizing the native state include the interaction of buried carbonyl oxygen atoms with the edge of Phe 49 and a bias toward statistically preferred side-chain dihedral angles. There is substantial disorder at both ends of the 61 amino acid protein. A 51-amino acid variant of engrailed (residues 6-56) was synthesized and shown by CD and thermal denaturation studies to be structurally and thermodynamically similar to the full-length domain.
Security for the cloud infrastructure: Trusted virtual data center implementation (2009)

The trusted virtual data center (TVDc) is a technology developed to address the need for strong isolation and integrity guarantees in virtualized environments. In this paper, we extend previous work on the TVDc by implementing controlled access to networked storage based on security labels and by implementing management prototypes that demonstrate the enforcement of isolation constraints and integrity checking. In addition, we extend the management paradigm for the TVDc with a hierarchical administration model based on trusted virtual domains and describe the challenges for future research.
The Oxidation of Metal Alloy Foils in the Presence of Water Vapor (2003)

Water vapor can be detrimental to the elevated temperature oxidation resistance of alloys that rely on the formation of a protective chromium oxide layer. The resulting degradation can be significant, particularly when such alloys are in the form of light gauge sheet and strip. Long term test results will be presented for commercially available wrought austenitic stainless steels and for the nickel-base superalloys 625 and HX exposed at 1300°F and 1400°F in environments containing various levels of water vapor.
Noninvasive Radiological Diagnosis of Renal Vein Thrombosis in Renal Transplantation (1991)

Thrombosis of the allograft renal vein is a rare complication of renal transplantation. Of 557 consecutive renal transplants performed between January 1, 1985 and November 30, 1989, 3 cases occurred for an over-all incidence of 0.4%. In 2 cases the diagnosis was made preoperatively with renal scintigraphy and duplex Doppler sonography. No graft was salvaged, despite timely diagnosis in 2 patients. We conclude that the diagnosis of renal vein thrombosis in the renal allograft recipient should be suspected clinically and by the radiographic findings of absent perfusion on renal scintigraphy, and the detection of an arterial signal, albeit abnormal, on duplex Doppler sonography. When diagnosed, nephrectomy appears to be the only treatment.
Current worldwide practice of dialysis dose prescription in acute renal failure (2006)

Gate postdoping to decouple implant/anneal for gate, source/drain, and extension: maximizing polysilicon gate activation for 0.1 μm CMOS technologies (2003)

We present a systematic study on maximizing polysilicon gate activation for aggressively scaled 0.1 /spl mu/m CMOS technologies. The fundamental limit of gate activation due to poly depletion effect was investigated in terms of gate implant/anneal condition and sequence, poly grain size, dopant penetration and activation. For the first time, we achieved significant improvement in CMOS performance by developing a novel process of "gate postdoping" to decouple implant and anneals for gate, source/drain, and extension. The method successfully reduces the poly depletion effect and thus the equivalent gate oxide thickness in inversion by up to /spl sim/2 /spl Aring/, improving CMOS on-currents by 9/spl sim/33% over a conventional process.
Towards Accurate Measurement of Computer Usage in a Rural Kiosk (2005)

Abstract. Rural PC kiosks are increasingly seen as a tool for socio-economic development in developing countries. In order to make kiosks successful, it helps to understand patterns of usage in existing kiosks. Often, questionnaires or interviews are conducted to determine usage patterns, but self-reporting by subjects is notoriously inaccurate. In this paper, we present a tool that allows accurate measurement of when and how PCs in a kiosk are being used. We discuss how an existing tool has been adapted for easy data collection in rural kiosks and present evidence that even regular users of computers are poor at estimating their own usage statistics. 1
MOUSE SKIN PHOTOSENSITIVITY WITH DIHAEMATOPORPHYRIN ETHER (DHE) AND ALUMINIUM SULPHONATED PHTHALOCYANINE (AlSPc) (1989)

Skin photosensitivity of sun exposed sites is the major side effect of dihaematoporphyrin ether (DHE) photodynamic therapy (PDT). Reports of severe oedema and erythema have generally been anecdotal. We have studied aluminium sulphonated phthalocyanine (AlSPc) as a potential photosensitiser for PDT. In this paper we report our work comparing the skin photosensitivity reactions of DHE and AlSPc. We have studied: (i) the time course of the skin reactions, (ii) the effect of increasing time from administration of photosensitiser to irradiation, (iii) drug-skin reaction dose response. Groups of Skh I female hairless albino mice were given an intravenous bolus dose of either 0.9% saline solution, AlSPc or DHE (Photofrin II). Drug doses ranged from 0.5 to 50 mg/kg. At times ranging from 1 h to 1 month animals were irradiated with a range of doses of solar simulated radiation (SSR). The skin reaction was observed over a 2 week period. DHE reactions were always more severe than those with AlSPc. Peak skin reaction was seen at 3 h for DHE and 6 h for AlSPc. DHE reactions were still visible 2 weeks after irradiation whereas the AlSPc reaction disappeared by 48 h. Irradiation evoked a reaction up to 2 months after administration of DHE but only up to 2 weeks with AlSPc. The mean SSR dose at which a skin reaction was seen decreased with increasing dose of both agents. The rate of decrease was slower with AlSPc than DHE. This study suggests that in PDT, AlSPc will cause much less skin photosensitivity than DHE.
