FPGA implementation of multi parameter deinterleaving (2014)

Electronic warfare (EW) is defined as military action involving the use of electromagnetic and directed energy to control the electromagnetic spectrum or to attack the enemy. One possible task of an EW system is to sort and classify received pulses from a dense environment of hostile radars so that the pulses can be processed. this process is known as pulse deinterleaving. The deinterleaving process needs to be completed with very low latency to support timely decision making required in modern EW environments. One method for deinterleaving streams of incoming radar pulses is incremental clustering. Clustering is the unsupervised partitioning of similar data samples into groups called clusters. The goal is to create clusters in which members of a particular cluster are as similar as possible to one another and as different as possible from members of other clusters. Many clustering algorithms require a complete data set to be present a priori and require multiple passes through the data in order to produce a result. Such algorithms are referred to as non-incremental. On the other hand an incremental clustering algorithm considers each input data point only once at which point it assigns it to a cluster. Such a technique allows streaming data such as radar pulse descriptor words (PDWs) to be clustered in real time.
Fibroblast Growth Factor-8 Expression Is Regulated by Intronic Engrailed and Pbx1-binding Sites (1999)

Fibroblast growth factor-8 (FGF8) plays a critical role in vertebrate development and is expressed normally in temporally and spatially restricted regions of the vertebrate embryo. We now report on the identification of regions of Fgf8 important for its transcriptional regulation in murine ES cell-derived embryoid bodies. Stable transfection of ES cells, using a human growth hormone reporter gene, was employed to identify regions of the Fgf8 gene with promoter/enhancer activity. A 2-kilobase 5' region of Fgf8 was shown to contain promoter activity. A 0.8-kilobase fragment derived from the large intron of Fgf8 was found to enhance human growth hormone expressed from the Fgf8 promoter 3-4-fold in an orientation dependent manner. The intronic fragment contains DNA-binding sites for the AP2, Pbx1, and Engrailed transcription factors. Gel shift and Western blot experiments documented the presence of these transcription factors in nuclear extracts from ES cell embryoid bodies. In vitro mutagenesis of the Engrailed or Pbx1 site demonstrated that these sites modulate the activity of the intronic fragment. In addition, in vitro mutagenesis of both Engrailed and Pbx1 sites indicated that other unidentified sites are responsible for the transcriptional enhancement observed with the intronic fragment.
A Worst-case Performance of the Shortest-processing-time Heuristic for Single Machine Scheduling (1991)

This paper analyses a worst-case performance of the shortest-processing-time (SPT) heuristic in minimizing a quadratic function of job lateness for single machine scheduling. A sufficient condition on processing-plus-wait due dates is found for the SPT sequence to be optimal. A worst-case lower bound to the optimal solution is derived from the SPT sequence. It is then shown that the SPT sequence is asymptotically optimal. Extensive computational experiments suggest that the SPT heuristic may be a good choice for just-in-time production.

Variation in the colour of broiler breast fillets in the UK (2000)

1. The normal range in colour of broiler breast muscle was assessed using an objective (instrumental) measure of colour in portioned breast fillets at a commercial processing plant. In addition, the relationship between colour and ultimate muscle pH (pH(ult)) was also examined. 2. Considerable variation in colour was evident although minimal inter-flock variation was found. The exceptions were 2 free range flocks which produced breast fillets significantly lighter and less red. 3. Extremes of colour are likely to be discriminated against at the point of purchase. 4. A clear relationship between pH(ult) and L* values was found which provides more evidence for the existence of a PSE like condition in broiler breast meat.
CO_2 Absorption of Li_4SiO_4 at High Temperature (2006)

Li4SiO4 used as a CO2 absorbent at 500 ℃ to 750 ℃ was synthesized by SiO2 and Li2CO3. The crystal structure and microstructure of Li4SiO4 materials were characterized by XRD and SEM, respectively, and the CO2-absorption ability of the Li4SiO4 materials was studied by TG. The results showed that Li4SiO4 with good ability of CO2 absorption could be prepared at 750 ℃ for 6 h. The absorbing balance in CO2 atmosphere could be arrived during 15 min at 700 ℃, and the absorption amount was about 43%(wt). The synthesis conditions were optimized and the absorption capacity was improved as compared to literature methods.
A large-scale purification of phosphatidylethanolamine, lysophosphatidylethanolamine, and phosphatidylcholine by high performance liquid chromatography: a partial resolution of molecular species (1977)

Egg yolk phospholipids, on a 10 g scale, were resolved by high-performance liquid chromatography on an 8-m silica column with elution by a stepwise chloroform- methanol gradient into homogeneous phosphatidylcholine, phosphatidylinositol, phosphatidylethanolamine, and lyso- phosphatidylethanolamine fractions. Within these frac- tions, partial resolution on the basis of fatty acyl side chain composition was achieved.

Establishment of Clonal Strains of Rat Pituitary Tumor Cells That Secrete Growth Hormone<sup>1</sup><sup>,</sup><sup>2</sup> (1968)

Three clonal strains of epithelial cells were established from a transplantable rat pituitary tumor. These strains have been serially propagated for 14–25 months. They were subcultured every 2–3 weeks. Cells of the original strain have increased by a factor of more than 1040. The generation times of the 3 lines were similar and ranged between 30 and 40 hr. Cells of all 3 strains synthesize growth hormone and secrete it into the culture medium. Growth hormone synthesized in vitro is indistinguishable from normal rat pituitary growth hormone as measured by micro-complement fixation and radioimmunoassay. The specific activity of growth hormone production was estimated to be 20–40 figμng cell nitrogen/24 hr for the most vigorous strain. There has been no decrease in the rate of cell division nor decline in growth hormone secretion since the cells were established in culture. (Endocrinology82: 342, 1968)
Building Relatedness Through Hashtags: Social Influence and Motivation Within Social Media-Based Online Discussion Forums (2016)

In the last two decades, the mainstream growth of the Internet has led to transformative change in education, particularly higher education, as the Internet has provided new opportunities for learning online and at a distance (Allen & Seaman, 2010, Shea & Bidjerano, 2010). Commensurate with this has been a rise in the sphere of online activity known as social media - networks of users tied together via Web 2.0-based applications that offer users an opportunity to generate and share content of their own (Kaplan & Haenlein, 2010). A recent development in the world of social media is the introduction of so-called hashtags, represented symbolically by the # or pound sign symbol, joining use together, even if they don``t know each other (Ebner, Beham, Costa, & Reinhardt, 2009, Page, 2012). Easy to create, hashtags have become a unique way to experience global events, have political debates, or meet people with similar interests. For some time, online discussion forums have been a preferred pedagogical method of generating and facilitating discussion in online education and classrooms with online components (Mazzolini & Maddison, 2003, Rossman, 1999). Online discussion forums are typically administered through the built-in tools of a Learning Management System (LMS). Although LMSs offer basic tools for class instruction and management, there is debate as to the limits of their pedagogical value (Hong, 2008, Martindale & Wiley, 2004). The pedagogical concept of Personal Learning Environments (PLEs) challenges the dominance of LMS usage in online courses, bringing a student-centered and bottom-up perspective to online education. The thinking behind PLEs is that instruction should be situated in an environment more congruent with the learners`` typical technology usage for their personal lives, such as social media (Attwell, 2007). The purpose of this presentation is to share the research results of a study investigating the motivation of student``s participation in an online discussion forum when moved from an LMS to a class Twitter hashtag group. Twitter activity was analyzed, and respondents were surveyed on their intrinsic motivation in online discussions, social influences on their social media choice, and if their previous experience with social media affected motivation.
On development of a hybrid mode scanning phased array antenna (1992)

The versatile features of the hybrid mode scanning antenna to meet the stringent low-level surveillance requirements in the tactical environment are presented. The advantage of this antenna implemented in search radar over traditional antennas is that the antenna has a narrow pencil beam which allows placing the antenna beam very close to the ground for detection of a low-altitude penetrator. Then, with wide angle beam steering coverage, the antenna can lay its beams at various heights just above the local crest to catch the pop-up target. Finally, an electronic azimuth back-scan function provided by the antenna permits target detection and verification on the same antenna scan.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Wireless power transfer for free positioning using compact planar multiple self-resonators (2012)

In this paper, a wireless power transfer (WPT) system supporting free positioning in a large area is proposed. The main coupling unit of the proposed system consists of a transmitter with 5 self-resonators and a receiver with a self-resonator. By circuit analysis, the proposed system is analyzed. The fabricated coils are compact planar rectangular spiral types. The total size of the transmitter is 96 cm × 16 cm. The receiver is 10 cm × 10 cm. With the exception of the 5 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">th</sup> resonator in the transmitter, their resonant frequencies are 6.78 MHz. There are some regions with less than 50% power transfer efficiency (called a dead zone). By changing the 5 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">th</sup> resonator's frequency, the area of the dead zone can be reduced. When the 5 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">th</sup> resonator's resonant frequency f <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">5</inf> is 6.78 MHz, a system has 40% dead zone of the transmitter and power transfer efficiencies of 57% ∼ 87% in the other regions. On the other hand, when f <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">5</inf> is 6.38 MHz, a system has 10% dead zone and power transfer efficiencies of 70% ∼ 86% in other regions. The measured power transfer efficiencies are approximately consistent with the calculated results.
Design for global manufacturing and assembly∗ (1997)

In this paper the author presents and tests new concurrent engineering strategies that focus on manufacturing and assembly operations with a global perspective. Specifically, the focus is upon new design for manufacturability and assembly (DFMA) strategies to support multi-facility, global operations. These DFMA strategies are more holistic than most published techniques in that they focus on total system approaches that explicitly consider product mix, process configuration, and capital procurement strategies, as well as tooling, design, and set-up costs associated with manufacture and assembly. Furthermore, the DFMA strategies presented here consider the cost of transportation logistics in multi-facility, global manufacturing, assembly, and distribution networks., A general mathematical formulation is presented and tested under realistic conditions. It is demonstrated that this model can be used for capacity planning and product sourcing for multiple part types in many facilities. Similarly, it can be used to examine the sensitivity of solutions to changes in various costs, productivity levels, or product configuration and mix assumptions at each facility. Test results demonstrate the efficacy of use of the formulation in general terms. Finally, a research agenda is posited for the future development of the strategies.
The impact of high and low dose ionising radiation on the central nervous system (2016)

Responses of the central nervous system (CNS) to stressors and injuries, such as ionising radiation, are modulated by the concomitant responses of the brains innate immune effector cells, microglia. Exposure to high doses of ionising radiation in brain tissue leads to the expression and release of biochemical mediators of 'neuroinflammation', such as pro-inflammatory cytokines and reactive oxygen species (ROS), leading to tissue destruction. Contrastingly, low dose ionising radiation may reduce vulnerability to subsequent exposure of ionising radiation, largely through the stimulation of adaptive responses, such as antioxidant defences. These disparate responses may be reflective of non-linear differential microglial activation at low and high doses, manifesting as an anti-inflammatory or pro-inflammatory functional state. Biomarkers of pathology in the brain, such as the mitochondrial Translocator Protein 18kDa (TSPO), have facilitated in vivo characterisation of microglial activation and 'neuroinflammation' in many pathological states of the CNS, though the exact function of TSPO in these responses remains elusive. Based on the known responsiveness of TSPO expression to a wide range of noxious stimuli, we discuss TSPO as a potential biomarker of radiation-induced effects.
Design and Evaluation of a Hierarchical Service Management Method using Bloom Filters for Large MANETs (2008)

Mobile ad hoc networks (MANETs) conveniently complement infrastructure-based networks, allowing mobile nodes to spontaneously form a network and share their services, including bridging with other networks, either infrastructure-based or ad hoc. However, distributed sensor provisioning over MANETs requires adequate support for service discovery and invocation, due to the network's dynamics and resource constraints of wireless nodes. We propose a hierarchical service management method using bloom filters for large MANETs. In this paper, a MANET is comprised of logical grid hierarchy, and each mobile node within the lowest service region multicasts the attenuated bloom filter (ABF) for services itself to other nodes within the region. To advertise and discover a service efficiently, the server node of the lowest server region sends the summary bloom filter (SBF) for the ABFs to the server node of upper server region. Each upper server has the set of SBFs for lower vicinity service regions. The performance of the proposed method is evaluated by an analytical model, and is compared with that of two alternative advertisement solutions.
Geospatial Representation of River Channels (2005)

A geographic information system (GIS) approach for creating a three-dimensional (3D) topographic data set for straight or meandering river channels is presented. As input, the approach requires channel banklines, an initially arbitrary centerline, and a set of (x,y,z) river bathymetry points. A curvilinear orthogonal s,n-coordinate system that references data along and transverse to flow in the river channel is used. The methodology includes locating the channel centerline along the thalweg and then using it as a reference for assigning s,n-coordinates to the bathymetric data. The resulting bathymetric data in the s,n,z-coordinate system are used to create a square mesh, or FishNet, and this FishNet is then transformed back to the original x,y,z-coordinates to get a flow-oriented 3D mesh. The resulting 3D mesh is a network of lines transverse to the flow (cross sections) and lines parallel to the flow (profile lines). The output thus provides a flow-oriented 3D representation of channel geometry that can be used for river habitat and hydraulic modeling.
Síndrome de Gerstman secundario a malformación arteriovenosa del lóbulo parietal izquierdo. Reporte de caso (2018)

El síndrome de Gerstman se caracteriza porque los pacientes presentan 4 síntomas: alteraciones en la capacidad de expresar ideas por la escritura (agrafia), incapacidad para contar y realizar operaciones aritméticas sencillas (acalculia), imposibilidad de reconocer los dedos de la mano (agnosia digital) y desorientación derecha izquierda. Se asocia habitualmente con la lesión de una parte específica del cerebro, el giro angular del lóbulo parietal del hemisferio izquierdo. Habitualmente suele ser secundario a un accidentecerebro-vascular cerebral que afecta el territorio de la arteria cerebral media. La importancia del cuadro radica en su pronta detección por las consecuencias como afectación del lóbulo parietal posterior dominante para el lenguaje. El objetivo: es hacer una correlación anátomo-clínico-quirúrgica de este síndrome. A continuación se enmarca un caso de malformación arteriovenosa en la región parietal izquierda una paciente que consultó al departamento de Neurocirugía del Hospital Roosevelt por cefalea y alteración conductual.
Phase retrieval via linear programming: Fundamental limits and algorithmic improvements (2017)

A recently proposed convex formulation of the phase retrieval problem estimates the unknown signal by solving a simple linear program. This new scheme, known as PhaseMax, is computationally efficient compared to standard convex relaxation methods based on lifting techniques. In this paper, we present an exact performance analysis of PhaseMax under Gaussian measurements in the large system limit. In contrast to previously known performance bounds in the literature, our results are asymptotically exact and they also reveal a sharp phase transition phenomenon. Furthermore, the geometrical insights gained from our analysis led us to a novel nonconvex formulation of the phase retrieval problem and an accompanying iterative algorithm based on successive linearization and maximization over a polytope. This new algorithm, which we call PhaseLamp, has provably superior recovery performance over the original PhaseMax method.
Redundant role of DEAD box proteins p68 (Ddx5) and p72/p82 (Ddx17) in ribosome biogenesis and cell proliferation (2007)

The DEAD box proteins encoded by the genes ddx5 (p68) and ddx17 (isoforms p72 and p82) are more closely related to each other than to any other member of their family. We found that p68 negatively controls p72/p82 gene expression but not vice versa. Knocking down of either gene does not affect cell proliferation, in case of p68 suppression, however, only on condition that p72/p82 overexpression was granted. In contrast, co-silencing of both genes causes perturbation of nucleolar structure and cell death. In mutant studies, the apparently redundant role(s) of p68 and p72/p82 correspond to their ability to catalyze RNA rearrangement rather than RNA unwinding reactions. In search for possible physiological targets of this RNA rearrangement activity it is shown that the nucleolytic cleavage of 32S pre-rRNA is reduced after p68 subfamily knock-down, most probably due to a failure in the structural rearrangement process within the pre-60S ribosomal subunit preceding the processing of 32S pre-rRNA.

Synthetic Herbivore-Induced Plant Volatiles as Field Attractants for Beneficial Insects (2003)

Evidence for eld attraction by benecial insects to synthetic herbivore-induced plant volatiles (HIPVs) is presented. Three synthetic HIPVs (methyl salicylate, (Z)-3-hexenyl acetate, (E)-4,8-dimethyl-1,3,7-nonatriene) were evaluated in a Washington state hop yard during April October 2002 for attractiveness to benecial insects. The predatory mirid, Deraeocoris brevis (Uhler), and the anthocorid, Orius tristicolor (White), were attracted to sticky cards baited with (E)-3-hexenyl acetate, while the geocorid, Geocoris pallens Stal., and hover ies (Syrphidae) were attracted to methyl salicylate-baited cards. The coccinellid, Stethorus punctum picipes (Casey), was attracted to both HIPVs in July and September. The (E)-4,8-dimethyl-1,3,7-nonatriene did not attract any benecial insects. Lygus hesperus Knight, Leptothrips mali (Fitch), Anagrus spp., other Miridae, Coccinellidae, and parasitic Hymenoptera were not attracted to the three HIPVs tested. The possible exploitation of HIPVs in enhancing spring populations of benecial insects and conservation biological control in cropping systems is discussed.
Application of EPR Spectroscopy to Oxidative Removal of Organic Materials (1983)

Oxidative species produced in a microwave discharge ( and ) have been detected, and some of their reactions with organic solids characterized using a gas phase electron paramagnetic resonance (EPR) spectrometer assembled for that purpose. It has been shown that O atoms rather than excited‐state oxygen molecules are the primary reactive species responsible for removal. Also, the O atom oxidation of phenolformaldehyde polymers and graphite has been investigated. The recombination kinetics of O atoms in this flow system can be described by an exponential decay equation involving both wall‐ and gas‐phase collisional recombinations. This allows the signal observed downstream of the reaction to be interpreted as an indication of the gas‐solid reaction rate and thus allows the determination of the activation energies of removal of photoresist (0.5 eV) and graphite (0.45 eV). These experiments have established EPR as a useful analytical tool in the development of gaseous cleaning and other, analogous processes, such as etching.
