Certification and Source Verification in the Grain Handling Industry (2003)

Source verification (lot identity) is the ability to trace products from their initial components through a production and distribution system to an end user. Source verification is a documentation process that may also require product testing, special logistics, or other actions. Formal certification and audit is generally required. Grain markets have traditionally handled interchangeable average quality commodities. Biotechnology, safety/security concerns, and new consumer perceptions are converging to create a grain market need for source verification and the associated quality management certification systems. Iowa State has assisted a large grain firm with the application of quality management systems, product tracing, and implementation of related statistical process controls. The grain firm has already achieved certification by an industry quality system and is moving to ISO 9000 (2000). A major goal is the ability to track product completely for individual production unit to user – a challenge for the grain firm handling bulk commodities. However, the act of creating the quality management system generated significant operating cost efficiencies applicable to its general commodity business. This presentation uses the case study of the grain elevator to illustrate the needs, actions, and challenges of introducing source verification and certification to the grain market. Data from other elevator studies is used to illustrate program costs. Source verification and certification will change the mindset of agricultural businesses. In addition to providing security for very specialized products with restricted markets, this effort will reduce operating costs because a rigorous study of work processes is required for implementation. The conversion of commodity markets to product markets will improve profitability and efficiency of market participants. The tolerance for purity in both specialty and commodity markets will determine the actual costs associated with the programs

Boron nitride substrates for high mobility chemical vapor deposited graphene (2011)

Chemical vapor deposited (CVD) graphene is often presented as a scalable solution to graphene device fabrication, but to date such graphene has exhibited lower mobility than that produced by exfoliation. Using a boron nitride underlayer, we achieve mobilities as high as 37 000 cm2/V s, an order of magnitude higher than commonly reported for CVD graphene and better than most exfoliated graphene. This result demonstrates that the barrier to scalable, high mobility CVD graphene is not the growth technique but rather the choice of a substrate that minimizes carrier scattering.
Methodology of MOSFET characteristics fluctuation description using BSIM3v3 SPICE model for statistical circuit simulations (2002)

A methodology for inclusion of MOSFET characteristics fluctuation into BSIM3v3 SPICE model is proposed. Fundamentally physical parameters such as gate oxide thickness (TOX), channel concentration (NCH), gate length (L), and parasitic resistance (RDSW) are chosen as an independent parameter set. Parameters which should be expressed by the above set are described in simple physical equations. This method allows not only statistical simulation based on electric test data that can be easily measured with a full-auto tester system, but also characteristics prediction of modified device structures or of future technology devices.
Lessons from HIV-1 vaccine efficacy trials (2016)

An HIV-1 vaccine is urgently needed. Increased industry involvement, mobilization of resources, expansion of a robust pipeline of new concepts, and robust preclinical challenge studies will be essential to accelerate efficacy testing of next generation HIV-1 vaccine candidates.
Prediction of Epitopes in Hemagglutinin and Neuraminidase Proteins of Influenza A Virus H5N1 Strain: A Clue for Diagnostic and Vaccine Development (2008)

The avian influenza is an important infectious disease of birds. The genome of influenza A virus was segmented, single-stranded, negative-sense RNA molecules, which encodes many proteins. The significant surface proteins are hemagglutinin and neuraminidase for the pathogenicity of birds to humans. The prediction of epitopes in protein provides a suitable primary immunodiagnostic antigen for the detection of the influenza A virus H5N1. It was further used in the development and approval of epitopes, which were used as antigens, and the peptides can be used for vaccines in the potential control of an emerging pandemic of this pathogen. The conserved epitopes may be useful for the diagnosis of animals infected with the influenza virus. These might be helpful to prevent the spreading of influenza in animal to animal and also in the prevention and monitoring of its spread in the newer region. The epitopes provide the support for serodiagnosis or as a protective immunogen in novel vaccines. In this study, the preliminary data from the in silico analysis of hemagglutinin and neuraminidase was done to find potential T-cell epitopes. The determined peptides were beneficial for vaccine development, as they can reduce time by minimizing the number of required tests to find the possible selected epitopes, which target for vaccine development. T-cell recognition of the peptide-major histocompatible complex (MHC) is a prerequisite for cellular immunity. This work examines existing computational strategies for the study of peptide-MHC interactions. We have also provided guidelines for predicting antigenic peptides based on the availability of existing experimental data.
Network synchronisation for UTRA TDD (2002)

We present an overview and simulation results for the time and optionally also frequency synchronisation of cells in the UTRA TDD system. The method shown is in the process of being standardised for the Rel-4 in the 3GPP TSG RAN group. It is based on infrequent transmission of special synchronisation bursts over the air interface. The receive timing of these transmissions is measured by neighbouring cells and reported to the RNC (radio network controller), which in turn transmits timing updates to the cells. The overall control lies within the RNC which also computes the receive and transmit schedule for all cells. It is shown that a synchronisation accuracy of 100 ns can be achieved within a start-up time of approx. 400 seconds.
Thermoelectric composites of poly(3-hexylthiophene) and carbon nanotubes with a large power factor (2013)

Composite films of poly(3-hexylthiophene) and single- as well as multi-walled carbon nanotubes are demonstrated to offer a competitive thermoelectric performance. The power factor significantly exceeds values obtained with either constituent alone provided that the conjugated polymer is sufficiently p-doped. The use of single-walled carbon nanotubes consistently results in a higher electrical conductivity with a maximum value above 103 S cm−1 and thus gives rise to a power factor of 25 ± 6 μW m−1 K−2 for a filler content of only 8 wt% and a maximum 95 ± 12 μW m−1 K−2 for 42–81 wt%. Moreover, a carbon nanotube content of 8–10 wt% does not compromise the low bulk thermal conductivity of the polymer matrix, which promises a high figure of merit of at least ZT > 10−2 at room-temperature. All samples are cast on plastic substrates, emphasising their suitability for large-area, flexible thermoelectric applications.
A polymerase chain reaction‐based method for the detection of trisomy 12 in B chronic lymphocytic leukaemia (1993)

We report a polymerase chain reaction (PCR)-based method for detection of clonal trisomy 12 cell populations in B cell chronic lymphocytic leukaemia which is particularly applicable to retrospective analysis or archival material. The method utilizes three restriction enzyme site polymorphisms linked to the KRAS2 locus on chromosome 12 to monitor allele imbalance resulting from duplication of this chromosome. 21/24 unselected chronic lymphocytic leukaemia cases (88%) were informative for at least one polymorphism and of these, eight (33% of total cases) displayed allelic imbalance consistent with trisomy 12.
A generic communication scheduler for distributed DNN training acceleration (2019)

We present ByteScheduler, a generic communication scheduler for distributed DNN training acceleration. ByteScheduler is based on our principled analysis that partitioning and rearranging the tensor transmissions can result in optimal results in theory and good performance in real-world even with scheduling overhead. To make ByteScheduler work generally for various DNN training frameworks, we introduce a unified abstraction and a Dependency Proxy mechanism to enable communication scheduling without breaking the original dependencies in framework engines. We further introduce a Bayesian Optimization approach to auto-tune tensor partition size and other parameters for different training models under various networking conditions. ByteScheduler now supports TensorFlow, PyTorch, and MXNet without modifying their source code, and works well with both Parameter Server (PS) and all-reduce architectures for gradient synchronization, using either TCP or RDMA. Our experiments show that ByteScheduler accelerates training with all experimented system configurations and DNN models, by up to 196% (or 2.96X of original speed).
Repair of Postinfarction Ventricular Septal Defect (1994)

Recently I successfully repaired a necrotic, acute septal defect by modifying the standard intracavitary repair of postinfarction aneurysm. The technique was modified after a patient who had undergone standard intracavitary repair developed a systolic murmur and had to be returned to surgery, where I found that the continuous suture had become detached at the posterior extent of the repair. The pericardial baffle was reattached using interrupted sutures with felt pledgets. As a result of this experience, we have modified our standard intracavitary repair for postinfarction aneurysm to account for the area of necrotic myocardium often associated with acute septal defects.
Les jonctions serrées : Plate-forme de régulation de la prolifération et de la polarité cellulaires (2004)

Les jonctions serrees scellent les cellules epitheliales et endotheliales entre elles. Elles ont ete longtemps considerees comme de simples barrieres separant les deux compartiments membranaires apical et basolateral, dont la composition en proteines et lipides est differente. De recentes etudes montrent que diverses proteines impliquees dans la transduction de signaux et le trafic membranaire sont associees aux jonctions serrees. Ces dernieres servent de lieu d’integration et de transmission de signaux necessaires a la regulation de leur assemblage et a la polarisation cellulaire, mais aussi a la modulation de l’expression des genes requise pour la proliferation et la differenciation cellulaires.
CNT/PDMS-based canal-typed ear electrodes for inconspicuous EEG recording (2014)

These electrodes could be used to monitor EEG clinically, in ubiquitous health care and in brain-computer interfaces.
Optical-fiber-loop memory for multi wavelength packet buffering in ATM switching applications (1993)

In view of the evolution of future networks towards B-ISDN, which calls for high transport capacities, the combined use of wavelength routing, optical buffering, and wavelength multiplexing for advanced ATM switching nodes has been proposed1 as a way to overcome the bottlenecks of existing electronic technologies by exploiting photonics. On the basis of that approach, experimentation has begun in the framework of the RACE 2039 EEC project. This experimentation is aimed at the implementation of a demonstrative packet-switching subsystem that is based on a multiwavelength optical-fiber-loop memory.
Magnolol protects cortical neuronal cells from chemical hypoxia in rats (1998)

The protective effect of magnolol, a component of Magnolia officinalis, against hypoxia-induced cell injury in cortical neuron-astrocyte mixed cultures was examined. Exposure of the cells to chemical hypoxia (0.5 mM KCN) produced morphological changes in neurons but not in astrocytes. KCN induced dose- and time-dependent increases in release of LDH and decreases in viable cell number. Treatment with magnolol (10 and 100 microM) significantly reduced the KCN-induced LDH release in a concentration-dependent manner. A higher concentration (750 microM) magnolol was toxic. Nuclear condensation was not observed in KCN-treated cells, suggesting that chemical hypoxia-induced cell death was via necrosis, rather than via apoptosis. This is the first report demonstrating that magnolol protects neurons against chemical hypoxic damage or necrotic cell death in cortical neuron-astrocyte mixed cultures.
Anti‐Inflammatory Effects of 81 Chinese Herb Extracts and Their Correlation with the Characteristics of Traditional Chinese Medicine (2014)

Inducible nitrogen oxide synthase (iNOS) is the primary contributor of the overproduction of nitric oxide and its inhibitors have been actively sought as effective anti-inflammatory agents. In this study, we prepared 70% ethanol extracts from 81 Chinese herbs. These extracts were subsequently evaluated for their effect on nitrogen oxide (NO) production and cell growth in LPS/IFNγ-costimulated and unstimulated murine macrophage RAW264.7 cells by Griess reaction and MTT assay. Extracts of Daphne genkwa Sieb.et Zucc, Caesalpinia sappan L., Iles pubescens Hook.et Arn, Forsythia suspensa (Thunb.) Vahl, Zingiber officinale Rosc, Inula japonica Thunb., and Ligusticum chuanxiong Hort markedly inhibited NO production (inhibition > 90% at 100 μg/mL). Among active extracts (inhibition > 50% at 100 μg/mL), Rubia cordifolia L., Glycyrrhiza glabra L., Iles pubescens Hook.et Arn, Nigella glandulifera Freyn et Sint, Pueraria lobata (Willd.) Ohwi, and Scutellaria barbata D. Don displayed no cytotoxicity to unstimulated RAW246.7 cells while increasing the growth of LPS/IFNγ-costimulated cells. By analyzing the correlation between their activities and their Traditional Chinese Medicine (TCM) characteristics, herbs with pungent flavor displayed potent anti-inflammatory capability. Our study provides a series of potential anti-inflammatory herbs and suggests that herbs with pungent flavor are candidates of effective anti-inflammatory agents.
Comparative analysis of volatile metabolomics signals from melanoma and benign skin: a pilot study (2013)

The analysis of volatile organic compounds (VOC) as biomarkers of cancer is both promising and challenging. In this pilot study, we used an untargeted approach to compare volatile metabolomic signatures of melanoma and matched control non-neoplastic skin from the same patient. VOC from fresh (non-fixed) biopsied tissue were collected using the headspace solid phase micro extraction method (HS SPME) and analyzed by gas chromatography and mass spectrometry (GCMS). We applied the XCMS analysis platform and MetaboAnalyst software to reveal many differentially expressed metabolic features. Our analysis revealed increased levels of lauric acid (C12:0) and palmitic acid (C16:0) in melanoma. The identity of these compounds was confirmed by comparison with chemical standards. Increased levels of these fatty acids are likely to be a consequence of up-regulated de novo lipid synthesis, a known characteristic of cancer. Increased oxidative stress is likely to cause an additional increase in lauric acid. Implementation of this study design on larger number of cases will be necessary for the future metabolomics biomarker discovery applications.
Keypoint clustering for robust image matching (2010)

A number of popular image matching algorithms such as Scale Invariant Feature Transform (SIFT)1 are based on local image features. They first detect interest points (or keypoints) across an image and then compute descriptors based on patches around them. In this paper, we observe that in textured or feature-rich images, keypoints typically appear in clusters following patterns in the underlying structure. We show that such clustering phenomenon can be used to: 1) enhance recall and precision performance of the descriptor matching process, and 2) improve convergence rate of the RANSAC algorithm used in the geometric verification stage.
Privacy-triggered communications in pervasive social networks (2011)

Pervasive social networks extend traditional social networking by enabling users to share information in a peer-to-peer fashion using their wireless mobile devices. Contrary to traditional online social networks, privacy protection in such networks depends heavily on users' context (time, location, activity, etc.) and their sensitivity to the shared data and context. Existing privacy-preserving mechanisms do not adapt well to different data, context and user sensitivities. In this work, we follow a fresh approach for privacy preservation, called privacy-triggered communications; it allows users in such pervasive networks to dynamically regulate their communications based on their context and on the evolution of their privacy in that context. Our initial results show that this is a feasible strategy for privacy management in pervasive social networking scenarios.
One-by-one coupling of single photon emitters to high-Q modes of optical microresonators (2009)

We present the on-demand coupling of single NV- defect centers in nanodiamonds to a polystyrene microspherical resonator. From an ensemble on a coverslip we select out single nanodiamonds containing a single defect proven by a pronounced antibunching dip. With the help of a scanning near-field probe we can attach these nanodiamonds to a microsphere resonator one-by-one. A clearly modulated fluorescence spectrum demonstrates coupling of the single defect centers to high- whispering-allery modes. Our experiments establish a toolbox to assemble complex systems consisting of single quantum emitters and (coupled) microresonators.
Alternative Copolymerization of a Conjugated Segment and a Flexible Segment and Fabrication of a Fluorescent Sensing Film for HCl in the Vapor Phase (2012)

A novel fluorescently active co-oligomer (P1) was designed and prepared by alternative co-polymerization of oligo(p-phenyleneethynylene) (OPE), possessing two cholesterol-containing side chains, and ethanediamine. A control co-oligomer (P2) possessing similar structure to P1 was also prepared, but in this case the OPE bears no side chains. P1 and P2 have been used for the fabrication of two fluorescent films, film 1 and film 2, respectively. Fluorescence studies demonstrated that the emission of film 1 is sensitive and selective to the presence of trace amounts of HCl in air. In contrast, film 2 shows no such response. The quenching has been attributed to the protonation of the imino groups within the oligomer chains, and the difference in the sensing behaviors of the two films was rationalized by supposing the existence of molecular channels in film 1. The proposed mechanism is supported by the results from additional experiments and theoretical calculations. Furthermore, the film as fabricated is robust, and thereby it is believed that film 1 has the potential to be developed into a new generation of sensitive and selective HCl sensor.
Radio Frequency Magnetron-Sputtered LiCoPO[sub 4] Cathodes for 4.8 V Thin-Film Batteries (2003)

Thin-film batteries employing sputtered cathode layers, (LiPON) electrolyte, and Li anode films have been successfully fabricated and tested. The cells exhibit a high-voltage charge/discharge plateau of 4.8 V, with a lower plateau at 2.5 V corresponding to a much higher conductivity phase. Cells fabricated with as-deposited cathode layers are highly resistive and cannot be charged or discharged to appreciable capacities, even at very low rates of approximately C/100. Upon annealing, the films sputtered from the target become discontinuous and take on a granular morphology. X-ray diffraction results show that these grains consist of untextured crystalline on a Pt current collector layer, a finding further supported by the results from subsequent electrochemical analyses. Thin-film batteries fabricated with crystalline cathodes are among the highest voltage thin-film batteries yet reported. © 2003 The Electrochemical Society. All rights reserved.
Polarized light imaging specifies the anisotropy of light scattering in the superficial layer of a tissue (2016)

This report describes how optical images acquired using linearly polarized light can specify the anisotropy of scattering (g) and the ratio of reduced scattering [μs′=μs(1−g)] to absorption (μa), i.e., N′=μs′/μa. A camera acquired copolarized (HH) and crosspolarized (HV) reflectance images of a tissue (skin), which yielded images based on the intensity (I=HH+HV) and difference (Q=HH−HV) of reflectance images. Monte Carlo simulations generated an analysis grid (or lookup table), which mapped Q and I into a grid of g versus N′, i.e., g(Q,I) and N′(Q,I). The anisotropy g is interesting because it is sensitive to the submicrometer structure of biological tissues. Hence, polarized light imaging can monitor shifts in the submicrometer (50 to 1000 nm) structure of tissues. The Q values for forearm skin on two subjects (one Caucasian, one pigmented) were in the range of 0.046±0.007 (24), which is the mean±SD for 24 measurements on 8 skin sites×3 visible wavelengths, 470, 524, and 625 nm, which indicated g values of 0.67±0.07 (24).
LT3: A Multi-modular Approach to Automatic Taxonomy Construction (2015)

This paper describes our contribution to the SemEval-2015 task 17 on "Taxonomy Extraction Evaluation". We propose a hypernym detection system combining three modules: a lexico-syntactic pattern matcher, a morphosyntactic analyzer and a module retrieving hypernym relations from structured lexical resources. Our system ranked first in the competition when considering the gold standard and manual evaluation, and second in the overall ranking. In addition, the experimental results show that all modules contribute to finding hypernym relations between terms.
