Agile Condor: A scalable high performance embedded computing architecture (2015)

The Air Force Research Laboratory Information Directorate Advanced Computing and Communications Division is developing a new computing architecture, designed to provide high performance embedded computing (HPEC) pod solution to meet operational and tactical real-time processing intelligence surveillance and reconnaissance (ISR) missions. This newly designed system, Agile Condor, is a scalable and HPEC system based on open industry standards that will increase, far beyond the current state-of-the-art, computational capability within the restrictive size, weight and power constraints of unmanned aircraft systems' external “pod” payloads. The objective with such a system is to explore and develop innovative system solutions to meet future Air Force real-time HPEC; e.g., multi-mission, multi-function ISR processing and exploitation. While the core compute capability can be placed in various environments, our baseline design utilizes a 12-inch diameter flight-certified aeronautics pod that is scalable in length. Agile Condor can be connected to external data sources, or the nose and tail can be made of Radio Frequency (RF) transparent material, enabling the use of various RF sensing technologies within the same aeronautics enclosure. Inside this pod is a lightweight, thermally-efficient industry standard 3U VPX conduction cooled (with unconditioned ambient air) chassis that supports the required board and interface hardware. Agile Condor brings high-performance computing closer to sensors and immediately enables future research and development efforts in neuromorphic computing and autonomous system operations.
Extended Type 1 Chain Glycosphingolipids (1993)

Aberrant glycosylation associated with animal and human cancers has been clearly defined by improved chemical analysis of carbohydrates (CHOs) and introduction of monoclonal antibody (MAb) technology in tumor immunology. While ganglio-series and globo-series antigens have been found to be highly expressed as tumor-associated antigens (TAAs) in specific types of human cancer such as Burkitt lymphoma, melanoma, and neuroblastoma, lacto-series structures are more widely expressed in such common human cancers as gastrointestinal, pancreatic, lung, breast, and hepatic cancers (see for review 1). Two types of lacto-series antigens are known: type 1 and type 2 chain. Their fucosylated forms were discovered in 1964, and their structures were characterized subsequently (2-4). It was noticed that Lea and Leb antigens were both accumulated in human cancers regardless of host Lewis status. However, they were not widely recognized as human TAAs until the MAb approach was introduced in human tumor immunology. Accumulation of glycosphingolipids (GSLs)

Umbilical Cord Stem Cell Seeding on Fast-Resorbable Calcium Phosphate Bone Cement (2010)

Tissue engineering offers immense promise for bone regeneration. Human umbilical cord mesenchymal stem cells (hUCMSCs) can be collected without invasive procedures required for bone marrow MSCs. The objective of this study was to investigate the physical properties and the differentiation capacity of hUCMSCs on calcium phosphate cement (CPC) scaffolds with improved dissolution/resorption rates. CPC consisted of tetracalcium phosphate and dicalcium phosphate anhydrous, with various tetracalcium phosphate/dicalcium phosphate anhydrous ratios. At 1/3 ratio, CPC had a dissolution rate 40% faster than CPC control at 1/1. The faster-resorbable CPC had strength and modulus similar to CPC control. Their strength and modulus exceeded the reported values for cancellous bone, and were much higher than those of hydrogels and injectable polymers for cell delivery. hUCMSCs attached to the nano-apatitic CPC and proliferated rapidly. hUCMSCs differentiated into the osteogenic lineage, with significant increases in alkaline phosphatase activity, osteocalcin, collagen I, and osterix gene expression. In conclusion, in this study we reported that hUCMSCs attaching to CPC with high dissolution/resorption rate showed excellent proliferation and osteogenic differentiation. hUCMSCs delivered via high-strength CPC have the potential to be an inexhaustible and low-cost alternative to the gold-standard human bone marrow mesenchymal stem cells. These results may broadly impact stem-cell-based tissue engineering.
Dynamic risk analysis using alarm databases to improve process safety and product quality: Part I—Data compaction (2011)

Abstract In most industrial processes, vast amounts of data are recorded through their distributed control systems (DCSs) and emergency shutdown (ESD) systems. This two‐part article presents a dynamic risk analysis methodology that uses alarm databases to improve process safety and product quality. The methodology consists of three steps: (i) tracking of abnormal events over an extended period of time, (ii) event‐tree and set‐theoretic formulations to compact the abnormal‐event data, and (iii) Bayesian analysis to calculate the likelihood of the occurrence of incidents. Steps (i) and (ii) are presented in Part I and step (iii) in Part II. The event‐trees and set‐theoretic formulations allow compaction of massive numbers (millions) of abnormal events. For each abnormal event, associated with a process or quality variable, its path through the safety or quality systems designed to return its variable to the normal operation range is recorded. Event trees are prepared to record the successes and failures of each safety or quality system as it acts on each abnormal event. Over several months of operation, on the order of 10 6 paths through event trees are stored. The new set‐theoretic structure condenses the paths to a single compact data record, leading to significant improvement in the efficiency of the probabilistic calculations and permitting Bayesian analysis of large alarm databases in real time. As a case study, steps (i) and (ii) are applied to an industrial, fluidized‐catalytic‐cracker. © 2011 American Institute of Chemical Engineers AIChE J, 2012
Positional cloning of a novel gene on chromosome 16q causing Bardet-Biedl syndrome (BBS2) (2001)

Bardet-Biedl syndrome (BBS) is a genetically heterogeneous autosomal recessive disorder with the primary clinical features of obesity, pigmented retinopathy, polydactyly, hypogenitalism, mental retardation and renal anomalies. Associated features of the disorder include diabetes mellitus, hypertension and congenital heart disease. There are six known BBS loci, mapping to chromosomes 2, 3, 11, 15, 16 and 20. The BBS2 locus was initially mapped to an 18 cM interval on chromosome 16q21 with a large inbred Bedouin kindred. Further analysis of the Bedouin population allowed for the fine mapping of this locus to a 2 cM region distal to marker D16S408. Physical mapping and sequence analysis of this region resulted in the identification of a number of known genes and expressed sequence tag clusters. Mutation screening of a novel gene (BBS2) with a wide pattern of tissue expression revealed homozygous mutations in two inbred pedigrees, including the large Bedouin kindred used to initially identify the BBS2 locus. In addition, mutations were found in three of 18 unrelated BBS probands from small nuclear families.
Analog optical phase modulator based on chiral smectic and polymer cholesteric liquid crystals (1995)

A high-speed analog optical phase modulator based on chiral smectic and cholesteric liquid crystals is discussed. The chiral smectic liquid-crystal device functions as a variable-orientation half-wave retarder, whereas the polymer cholesteric liquid-crystal film acts as a polarization-preserving mirror. We use circular Jones calculus to describe optical phase modulation, using a half-wave retarder of variable orientation acting on circularly polarized light. The phase induced by this modulator is achromatic. Analog phase modulation of nearly 360° is demonstrated with a device switching time of 200 μs at 25 °C.
Large-area sheet task: advanced denritic-web-growth development. Annual report, October 23, 1980-October 22, 1981 (1982)

Significant progress has been made in our understanding of the web growth process. Thermal models have been developed that accurately predict the thermally generated stresses in the web crystal which, if too high, cause the crystal to degenerate. The application of the modeling results to the design of low-stress experimental growth configurations will allow growth of wider web crystals at higher growth velocities. A new experimental web growth machine was constructed. This facility includes all the features necessary for carrying out growth experiments under steady state thermal conditions. Programmed growth initiation has been developed to give reproducible crystal starts. Width control permits the growth of long ribbons at constant width. Melt level is controlled to 0.1 mm or better. Thus, the capability exists to grow long web crystals of constant width and thickness with little operator intervention, and web growth experiments can now be performed with growth variables controlled to a degree not previously possible.
An MRI-Compatible Probe Exchanger for Early Diagnosis and Treatment of Breast Cancer (2004)

The objective of this project is to develop a device to exchange interventional probes such as biopsy needles, local anesthesia, ablation tools, and lesion removal devices to perform multiple procedures for breast cancer diagnosis and treatment during single session in the MR scanner. Used as a supplement to an existing five degree-of-freedom (DOF) interventional probe positioning device, the apparatus is fitted with two additional DOF for the selection and exchange of interventional probes to be used in an automated probe positioning device. The entire system is constructed of MR compatible materials, i.e. non-magnetic and non-conductive, to eliminate artifacts and distortion of the MR images. The apparatus is remotely controlled by means of ultrasonic piezoelectric motors and a graphical user interface, providing MRI-guided planning and monitoring of the procedure while it is in progress. Based on a timing analysis, the device can quickly exchange a probe (48 seconds), thereby reducing the complexity and cost of the overall procedure.
Transforming Carbon Nanotube Devices into Nanoribbon Devices (2009)

Reported here is an extension of the nanotube longitudinal unzipping process to convert electrode-bound multiwalled carbon nanotube (MWCNT) devices into graphene nanoribbon devices. Microscopy and Raman spectroscopy were used to monitor the conversion process. The electrical properties of the devices were characterized. The efficacy of the unzipping protocol on device-bound MWCNTs is demonstrated.
Studies of application possibilities of the products of microcrystalline chitosan biodegradatio (2007)

Some of the chitosan properties depend largely upon its molecular structure and in several applications of this polymer its lowered molecular weight is an asset. By degrading of microcrystalline chitosan in the presence of cellulolytic enzymes, the products having a reduced molecular weight were prepared, together with awater soluble blend of oligomers. The outcome of an initial assessment, made to evaluate the chance of a practical use of the obtained products of chitosan degradation, indicates that oligomers and partly degraded microcrystalline chitosan accelerate the germination of seeds, inhibit the growth of plant viruses, bacteria and milder.

A multiscale approach illustrates the high power conversion efficiency (PCE) of a solar cells with oxychalcogenide perovskites. Based on the atomistic-scale properties, full device simulation maximizes the PCE by optimizing multiple properties in a device. This approach guides identification of potential oxychalcogenide perovskite solar cells. More details can be found in article number 1900766 by Fedwa El-Mellouhi and co-workers.
GeoCDX: An Automated Change Detection and Exploitation System for High-Resolution Satellite Imagery (2013)

We have developed a fully automated system for change detection of high-resolution satellite imagery. Our system, GeoCDX, is sensor-agnostic, resolution-independent and designed to process the very large volumes of data collected by modern high resolution panchromatic and multispectral imaging satellites. GeoCDX performs fully automated coregistration of imagery; extracts high-level features from the satellite imagery; performs change detection processing to pinpoint locations of change; clusters image tiles to group similar regions of change; and presents results in a variety of ways in an easy-to-use web application that facilitates online discovery, analysis, and dissemination of the change detection results. We applied GeoCDX to 4121 image pairs and successfully coregistered over 91% of the pairs covering a total area greater than 370 000 km <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ; GeoCDX decreased the average coregistration error from 9.6 ± 8.6 m to 1.8 ± 1.2 m. We show that for some pairs, GeoCDX provides up to a 50% increase in users' efficiency compared to manually performing change detection in common GIS software. Moreover, the change detection assessment performed using GeoCDX was on average four times more accurate compared to the manual approach in large part due to the use of our change intensity map that provides visual cues to the user during exploitation. Finally, change detection analysis using GeoCDX resulted in a missed detection rate of less than 2%.
<title>Proposal for a novel optical bus system using optical sheet bus technology</title> (1999)

Conventional electrical bus system technologies are encountered their physical borders in terms of transmission length and parasitic capacity of lines, and thus, many optical interconnection technologies are proposed to solve the problems in the electrical circuits. In this paper, we propose a new optical bus with sheet like shape technology using diffusion controlled light transmission in the multi- planar waveguides that makes capability of broadcasting, simultaneous bidirectional transmission, easy alignment and plural multiplex transmission. We have fabricated a basic model using optical sheet bus technology for the first time and evaluate them at 500MHz clock operation as follows: (1) synchronous broadcasting transmission to control transmission delay; (2) simultaneous bidirectional transmission in the same waveguide; (3) multiplex transmission such as time division multiplexing, wavelength division multiplexing and so on. Through this fabrication and evaluation, we can pick up some approach to put the optical sheet bus technology into practice with feature as follows: (a) simple design rule for multi-accessible bus systems like as shared memory bus systems, which needs faster speed; (b) added-value of multiplex transmission ways that reduce circuit frequency, minimize power consumption, maximize transmission bandwidth, and bring about no-wait communications for the bus systems.
Theory of time-gated phase-matching for isolated attosecond soft x-ray pulse generation using mid-infrared lasers (2014)

We model soft x-ray high harmonic generation and propagation driven by mid-infrared lasers. We find that multi-cycle laser pulses are ideal for generating shorter bright isolated attosecond pulses via time-gated phase-matching in high-density extended media.
Semantic video object segmentation and tracking using mathematical morphology and perspective motion model (2002)

This paper introduces a novel semantic video object extraction system using mathematical morphology and a perspective motion model. Inspired by the results from a study of the human visual system, we solve the semantic video object extraction problem in two steps: semi-automatic I-frame segmentation and automatic P-frame tracking. First, the precise semantic video object boundary can be found with the combined power of human assistance and a morphological segmentation tool. Second, the semantic video object in the remaining frames can be obtained using a global perspective motion estimation and compensation of the previous semantic video object plus boundary refinement as used for frames.
Human Milk Oligosaccharides in the Milk of Mothers Delivering Term versus Preterm Infants (2019)

Human milk oligosaccharides (HMOs) are a major component of human milk, and play an important role in protecting the infant from infections. Preterm infants are particularly vulnerable, but have improved outcomes if fed with human milk. This study aimed to determine if the HMO composition of preterm milk differed from that of term milk at equivalent stage of lactation and equivalent postmenstrual age. In all, 22 HMOs were analyzed in 500 samples of milk from 25 mothers breastfeeding very preterm infants (< 32 weeks of gestational age, < 1500g of birthweight) and 28 mothers breastfeeding term infants. The concentrations of most HMOs were comparable at equivalent postpartum age. However, HMOs containing α-1,2-linked fucose were reduced in concentration in preterm milk during the first month of lactation. The concentrations of a number of sialylated oligosaccharides were also different in preterm milk, in particular 3'-sialyllactose concentrations were elevated. At equivalent postmenstrual age, the concentrations of a number of HMOs were significantly different in preterm compared to term milk. The largest differences manifest around 40 weeks of postmenstrual age, when the milk of term infants contains the highest concentrations of HMOs. The observed differences warrant further investigation in view of their potential clinical impact.

Polymer-Based Organic Batteries (2016)

The storage of electric energy is of ever growing importance for our modern, technology-based society, and novel battery systems are in the focus of research. The substitution of conventional metals as redox-active material by organic materials offers a promising alternative for the next generation of rechargeable batteries since these organic batteries are excelling in charging speed and cycling stability. This review provides a comprehensive overview of these systems and discusses the numerous classes of organic, polymer-based active materials as well as auxiliary components of the battery, like additives or electrolytes. Moreover, a definition of important cell characteristics and an introduction to selected characterization techniques is provided, completed by the discussion of potential socio-economic impacts.
Microbial Production of 2-Deoxyribose 5-Phosphate from Acetaldehyde and Triosephosphate for the Synthesis of 2′-Deoxyribonucleosides (2003)

2-Deoxyribose 5-phosphate was produced from acetaldehyde and dihydroxyacetone phosphate via D-glyceraldehyde 3-phosphate by Klebsiella pneumoniae B-4-4 through deoxyriboaldolase- and triosephosphate isomerase-catalyzing reactions. Under the optimum conditions, 98.7 mM 2-deoxyribose 5-phosphate was produced from 200 mM acetaldehyde and 117 mM dihydroxyacetone phosphate in 2 h with a molar yield of 84%. The 2-deoxyriobse 5-phosphate produced was directly transformed to 2'-deoxyribonucleoside by phosphopentomutase- and nucleoside phosphorylase-catalyzing reactions.
New SAW antenna duplexers for single- and dual-band handy phones used in 800-MHz and 1.8-GHz cellular-radio systems (1999)

New SAW antenna duplexers used in EGSM/PCN dual-band handy phones have been developed. The differences between the single- and dual-band RF-circuit configurations are taken into considerations. Direct-parallel connection between the receiver SAW filter and the transmitter diode switch makes it possible to reduce the number of circuit elements and to achieve a small module size. The required frequency characteristics were also achieved.
