Diagnostics for local spectroscopic measurements in the divertor region of the Alcator C-Mod and DIII-D tokamaks (1997)

Local measurements of line emission of either intrinsic or gas puffed impurities will be performed around and below the X point. Such spectroscopic measurements, together with divertor Thomson scattering and bolometric imaging will enable estimates of divertor impurity particle distributions and power losses. A proposed multilayer mirror (MLM) diagnostic mounted inside the tokamak vessel will measure XUV (100–200 Å) emission from impurities at multiple locations in the divertor region of the C-Mod tokamak. A prototype of this instrument measuring N V at 162.6 Å is scheduled to be installed on C-Mod with a single chordal view of the X point. A multichordal/multispectral device using MLMs and gratings has been designed for the DIII-D tokamak. The instrument will measure the resonance emission of C II to C VI from 40–2000 Å, thus enabling a more direct and reliable estimate of the impurity content in the divertor. At DIII-D, the device will be mounted on a port below the mid plane avoiding spectroscopic contamination from the core plasma.
ModulAR: Eye-Controlled Vision Augmentations for Head Mounted Displays (2015)

In the last few years, the advancement of head mounted display technology and optics has opened up many new possibilities for the field of Augmented Reality. However, many commercial and prototype systems often have a single display modality, fixed field of view, or inflexible form factor. In this paper, we introduce Modular Augmented Reality (ModulAR), a hardware and software framework designed to improve flexibility and hands-free control of video see-through augmented reality displays and augmentative functionality. To accomplish this goal, we introduce the use of integrated eye tracking for on-demand control of vision augmentations such as optical zoom or field of view expansion. Physical modification of the device's configuration can be accomplished on the fly using interchangeable camera-lens modules that provide different types of vision enhancements. We implement and test functionality for several primary configurations using telescopic and fisheye camera-lens systems, though many other customizations are possible. We also implement a number of eye-based interactions in order to engage and control the vision augmentations in real time, and explore different methods for merging streams of augmented vision into the user's normal field of view. In a series of experiments, we conduct an in depth analysis of visual acuity and head and eye movement during search and recognition tasks. Results show that methods with larger field of view that utilize binary on/off and gradual zoom mechanisms outperform snapshot and sub-windowed methods and that type of eye engagement has little effect on performance.

Abstract The trisulfonyl amine (IIIa) is obtained from (IIa) and (I), whereas cleavage of the aminostannanes (VIa) or (VIb) [obtained from (IV) and (V)] with the sulfonyl chloride (IIb) yields (IIIb) and (IIIc).
Functional Analysis of Retrotransposons in Pea (1999)

The 5'-upstream regions of the plant active defense genes in pea (PSPAL2 and PSCHS1) exhibit significant nucleotide sequence identity to part of a copia-type retrotransposon. To characterize the retrotransposon in pea putative reverse transcriptase sequences (Psr) were amplified by PCR from cDNA prepared from protoplasts derived from pea suspension cultured cells. Psr genes can be classified into at least eight subgroups (A-H) according to their nucleotide sequence similarities. A subgroup PsrC was induced by the treatment of etiolated pea epicotyls with fungal elicitor within 30 min but was hardly induced by protoplasting of pea suspension cultured cells, whereas subgroups of PsrA and PsrB were highly induced by protoplasting. Interestingly, the retrotransposon sequence present at the 5'-upstream region of PSCHS1 which was induced by the treatment with fungal elicitor belonged to subgroup PsrC. The retrotransposon might play an important role in reorganization of the genes and optimization of the gene expression in response to various environmental stimuli such as an attack by phytopathogens or protoplasting.
Advanced Integrated Microwave Signal Processing With Giant On-Chip Brillouin Gain (2016)

Processing of microwave signals using photonics has several key advantages for applications in wireless communications. However, to bring photonic-based microwave signal processing to the mainstream requires a reduction of the form factor. Integration is a route for achieving high-performance, low-cost, and small-footprint microwave photonic devices. A high on-chip stimulated Brillouin scattering (SBS) gain is essential for synthesizing several key functionalities for advanced integrated microwave signal processing. We have optimized our on-chip SBS platform to achieve a record on-chip gain of 52 dB. In this paper, we discuss the implications of this giant gain from the viewpoint of new enabled technologies. The giant gain can be distributed over wide frequencies, which can be exploited for the realization of reconfigurable microwave bandpass, bandstop, and multiband filters. High gain also enables the demonstration of low-threshold on-chip lasers, which can be of relevance for a low-noise radio-frequency signal generation. These wide ranges of functionalities are made possible by the breakthrough on-chip gain makes Brillouin-based microwave photonic signal processing a promising approach for real-world implementation in the near future.
High-performance polysiloxane-based photorefractive polymers with nonlinear optical azo, stilbene, and tolane chromophores (1998)

The performance of photorefractive (PR) polymers strongly depends on the incorporated nonlinear-optical chromophores. We compare three polysiloxane-based PR guest–host polymers with an azo, a stilbene, and a tolane type of chromophore. Characteristic properties such as diffraction efficiency η, gain coefficient Γ, phase shift ϕ, modulation of the index of refraction Δn, and response time are measured as a function of the external electric field. Orientational enhancement as well as the influence of photoisomerization is observed and analyzed quantitatively. The materials show high performance with Δn&gt;1×10-2, corresponding to external diffraction efficiencies of 60% for samples of only 40-μm thickness.

Localized shape resonance on silver film perforated by H-shaped and more complex shaped hole arrays (2011)

The experimental results of light transmission through periodic array of H-shaped hole and more complicated hole which is a combination of multiple U shape are demonstrated. The observations indicate that the localized shape resonance in the longest resonant length of unfolded U-shaped part of the hole always appears. However, localized modes resonant in smaller U-shaped length don't always appear. Localized mode with non-U-shaped resonant path cannot be seen in our sample. In addition, localized mode with different order and resonant path can be excited by different polarized light.
Ring‐Opening Polymerization of ε‐Caprolactone by Poly(ethylene glycol) by an Activated Monomer Mechanism (2005)

Abstract Summary: The polymerization of ε ‐caprolactone (CL) in the presence of HCl · Et 2 O by an activated monomer mechanism was performed to synthesize diblock or triblock copolymers composed of poly(ethylene glycol) (PEG) and poly( ε ‐caprolactone) (PCL). The obtained PCLs had molecular weights close to the theoretical values calculated from the CL to PEG molar ratios and exibited monomodal GPC curves. We successfully prepared PEG and PCL block copolymers by a metal‐free method.

Rheumatoid Pneumoconiosis: A Comparative Study of Autopsy Cases between Japan and North America (2002)

In order to elucidate the prevalence of rheumatoid pneumoconiosis (RP), an extensive review was conducted of pathological specimens from a large series of autopsy cases both in Japan and the USA (National institute for Occupational Safety and Health). Twenty-two cases were pathologically identified as having RP among 2450 autopsied coal workers with pneumoconiosis in the USA (0.89%) and its prevalence was comparable with that of Japanese RP cases ( n = 9) among 1217 pneumoconiotics (0.74%). RP consisted of two subtypes, Caplan type and silicotic type. All Japanese cases were of the silicotic type (0.82%). In the USA 14 were of Caplan type (0.37%) and 8 silicotic (1.5%). Although RP is an uncommon disease, silicotics are relatively more prone to develop RP compared with other types of pneumoconiotics. The incidence of tuberculosis was significantly higher (9.1%) among RP cases than the non-rheumatoid population (1.5%) only in the US cases ( P < 0.01).
Trail-based approach for video data indexing and retrieval (2003)

Increasing use of multimedia data makes it crucial to use intelligent search mechanisms for retrieving multimedia data by content. Digital video requires the incorporation of temporal information for any effective content-based retrieval scheme. We present a trail-based model which uses the object motion information in order to characterize the events for subsequent searches for "similar" clips. Algorithms for different spatio-temporal search modes using various digital signal processing techniques are also introduced. We implemented the proposed methods and demonstrated that high-level query formulation can be achieved for the aforementioned purpose.

Maternal health challenges of pregnant women living on construction sites in Mumbai, Navi Mumbai, and Thane: A mixed-methods study (2016)

Background: Of the estimated 30 million construction workers in India 51% are women, however, there are no studies on pregnant women living on construction sites in the Indian population. 

Objective: The present study was conducted to collect information on health access and challenges of pregnant women living on construction sites in Mumbai, Navi Mumbai, and Thane. 

Material and Methods: Participants were pregnant women living on construction sites, and were recruited from 13 construction sites. A mixed methods study, using both quantitative survey and focus group discussions, was conducted to understand the usage of ANC, delivery, and PNC, and financing aspects to pregnancy-related healthcare utilization among these women. 

Results: In the survey, a total of 72 pregnant women were interviewed. The average age of respondents was found to be 22 years (±49SD). A total of 76% of these women had utilized the health facilities for their antenatal checkups (ANC) with majority (65%) utilizing private health facilities. Among women who had a delivery within last 2 years, borrowings from other family members and contractors, and use of current savings, was the most common form of financing of both ANC and delivery expenses. 16 women were found to be working at the time of data collection during their current pregnancy, and during the FGDs, it was mentioned that the women tend to work till seventh month of pregnancy. 

Conclusion: These findings underscore the need for considering various contextual factors in ensuring better living and maternal health access services for such women living on construction sites.
Effect of anthelminthic treatment on the immune response of mice. (1987)

Immunologic function was tested both in vivo and in vitro in mice undergoing prophylactic anthelminthic therapy with three agents to assess whether these drugs affected immune responses. This study was performed because investigators often are concerned about the effect of drug treatment on the induction of specific immune responses. While helminthic infestation is recognized as deleterious to the host, it is unclear whether anthelminthic treatment might be immunosuppressive. The effects of piperazine or trichlorphon administered to drinking water or fenbendazole administered in feed were insignificant in BALB/c mice. The induction of allospecific cytolytic T lymphocytes (CTLs) in vitro, influenza specific memory T cells in vivo, influenza specific antibody secretion in vivo, or influenza-specific helper T cells and CTLs in vitro were examined. Results of this study indicate that anthelminthic treatments did not interfere with immune responses.
"Fast" and "thick" e-beam resists exposed with multi-beam tool at 5 keV for implants and mature nodes: experimental and simulated model study (2015)

In addition to sub-20 nm technology nodes, multi-beam lithography at low-energy has also the capability to address mature CMOS technologies [130-45nm nodes] with high throughput and significant manufacturing costs reduction. It requires both “fast” resists for throughput gain and cost of ownership and “thick” resists matched with the current post-lithography processes such as etching and implant steps. We successfully demonstrated patterning of 45-130 nm nodes structures on different thick resists (up to 160 nm) with a 5 keV Mapper pre-alpha tool. In parallel, we developed a theoretical model to simulate 3D patterning showing good agreement with our experimental results.

Crystallization and preliminary crystallographic studies of Sfp: a phosphopantetheinyl transferase of modular peptide synthetases (1999)

The Bacillus subtilis Sfp protein is required for the non-ribosomal biosynthesis of the lipoheptapeptide antibiotic surfactin. It converts seven peptidyl carrier protein (PCP) domains of the surfactin synthetase SfrA-(A-C) to their active holo-forms by 4'-phosphopantetheinylation. The B. subtilis sfp gene was overexpressed in Escherichia coli and its gene product was purified to homogeneity and crystallized. Well diffracting single crystals were obtained from Sfp as well as from a selenomethionyl derivative, using sodium formate as a precipitant. The crystals belong to the tetragonal space group P41212/P43212, with unit-cell parameters a = b = 65.3, c = 150.5 A. They diffract beyond 2.8 A and contain one molecule in the asymmetric unit.
Chemical vapor infiltration (CVI) SiC whisker on carbon woven fabric for filter applications (2009)

β-silicon carbide whiskers have been synthesized on a carbon fabric by a vapor-solid (VS) mechanism using the Chemical Vapor Infiltration (CVI) process. Optimum processing conditions for SiC whisker growth were determined by mapping of SiC deposition behavior. SiC was deposited on a carbon fabric substrate as a film or whiskers, depending on processing conditions. The mean diameter and line density of the whiskers was the highest at an input gas ratio of 50. As temperature increases, the mean diameter of the whiskers increased and the line density of whiskers decreased. In the optimum processing conditions, whiskers grew uniformly with high growth density and formed a networking structure between each of the carbon filaments resulting in a structure suitable for filter applications.
Enhanced photo-sensitivity in a Si photodetector using a near-field assisted excitation (2019)

Abstract Silicon is an indispensable material in electric device technology. However, Si is an indirect bandgap material; therefore, its excitation efficiency, which requires phonon assistance, is low under propagating far-field light. To improve the excitation efficiency, herein we performed optical near-field excitation, which is confined in a nano-scale, where the interband transitions between different wave numbers are excited according to the uncertainty principle; thus, optical near-field can directly excite the carrier in the indirect bandgap. To evaluate the effect of optical near-field confined in a nano-scale, we fabricate the lateral Si p–n junction with Au nanoparticles as sources to generate the field confinement. We observed a 47.0% increase in the photo-sensitivity rate. In addition, by using the thin lateral p–n junction, which eliminates the far-field excitation, we confirmed a 42.3% increase in the photo-sensitivity rate.
Mode filtering approaches to acoustic source depth discrimination (2005)

Mode filtering in passive sonar represents a class of linear beamforming approaches in which the steering vectors are parameterized by the depth-dependent mode functions and horizontal wavenumbers that characterize propagation in a shallow waveguide. In this work, a mode-filter beamformer is combined with different decision metrics for the purpose of classifying the depth of an acoustic source. The concept is based on the premise that deep and shallow sources robustly separate in mode space. Experimental results using SwellEx-96 vertical line array data is shown. Performance dependence on parameters such as frequency and aperture sampling is discussed.
User Interface Matters: Analysing the Complexity of Mobile Applications from a Visual Perspective (2021)

Product-centric techniques to analyze mobile applications leverage traditional source code analysis, size, market success, complexity, and others. Many of these techniques converge in the strategy of evaluating metrics taken from the source code that delivers the functionality of the software product. However, when following the Model-View-Controller (MVC) architecture, mobile applications are typically constructed by a compound of at least two programming languages, one to deliver the functionality and the other to describe the visual aspects. The latter is commonly left out from source code analysis, even though critical parts of the application are present in the graphic User Interface (UI). In this paper, we identify an opportunity to strengthen the product-centric mobile app analysis by incorporating UI metrics. This approach aims to enhance the expressiveness of source code metrics and deliver a more comprehensive analysis of the complexity, maintainability, and effort estimation of a mobile app. To introduce the concept, we present a case study realized using a block-based programming language to create mobile apps, in which we describe and calculate functional and UI metrics, discover commonalities and differences, discuss traits, and open tracks for further research.

Critical Role of GFRα1 in the Development and Function of the Main Olfactory System (2012)

Glial cell line-derived neurotrophic factor (GDNF) and its receptor GFRα1 are prominently expressed in the olfactory epithelium (OE) and olfactory bulb (OB), but their importance for olfactory system development is completely unknown. We have investigated the consequences of GFRα1 deficiency for mouse olfactory system development and function. In the OE, GFRα1 was expressed in basal precursors, immature olfactory sensory neurons (OSNs), and olfactory ensheathing cells (OECs), but was excluded from mature OSNs. The OE of newborn Gfra1 knock-out mice was thinner and contained fewer OSNs, but more dividing precursors, suggesting deficient neurogenesis. Immature OSN axon bundles were enlarged and associated OECs increased, indicating impaired migration of OECs and OSN axons. In the OB, GFRα1 was expressed in immature OSN axons and OECs of the nerve layer, as well as mitral and tufted cells, but was excluded from GABAergic interneurons. In newborn knock-outs, the nerve layer was dramatically reduced, exhibiting fewer axons and OECs. Bulbs were smaller and presented fewer and disorganized glomeruli and a significant reduction in mitral cells. Numbers of tyrosine hydroxylase-, calbindin-, and calretinin-expressing interneurons were also reduced in newborn mice lacking Gfra1. At birth, the OE and OB of Gdnf knock-out mice displayed comparable phenotypes. Similar deficits were also found in adult heterozygous Gfra1(+/-) mutants, which in addition displayed diminished responses in behavioral tests of olfactory function. We conclude that GFRα1 is critical for the development and function of the main olfactory system, contributing to the development and allocation of all major classes of neurons and glial cells.
