Mark II Pro-Milk Tester for Estimation of Protein Percentage in Plant Milk Supplies (1973)

The Mark II Pro-Milk Tester was evaluated for its accuracy, repeatability, reliability, and operational limitations. During 1 yr the instrument calibration was checked continually with preanalyzed calibration milks prepared by combining individual cow milks at specific fat contents. Protein ranged from 2.96 to 4.24% by a semi-micro Kjeldahl method. Plant milk samples (833) were analyzed with the instrument and protein of these samples was from 2.75 to 3.65% by the Kjeldahl method.
Rapid Separation and Quantitative Analysis of Peptides Using a New Nanoelectrospray- Differential Mobility Spectrometer−Mass Spectrometer System (2006)

Differential mobility spectrometry (DMS) (see Buryakov, I. A.; Krylov, E. V.; Nazarov, E. G.; Rasulev, U. Kh. Int. J. Mass Spectrom. Ion Processes 1993, 128, 143-148), also commonly referred to as high-field asymmetric waveform ion mobility spectrometry (FAIMS) (see Purves, R. W.; Guevremont, R.; Day, S.; Pipich, C. W.; Matyjaszcyk, M. S. Rev. Sci. Instrum. 1998, 69, 4094-4105), is a rapidly advancing technology for gas-phase ion separation. The interfacing of DMS with mass spectrometry (MS) offers potential advantages over the use of mass spectrometry alone. Such advantages include improvements to mass spectral signal-to-noise, orthogonal/complementary ion separation to mass spectrometry, enhanced ion and complexation structural analysis, and the potential for rapid analyte quantitation. In this report, we investigate the use of our nanoESI-DMS-MS system to demonstrate differential mobility separation of peptides. The formation of higher order peptide aggregate ions (ion complexes) via electrospray ionization and the negative impact this has on DMS peptide separation are examined. The successful use of differential mobility drift gas modifiers (dopants) to reduce aggregate ion size and improve DMS peptide ion separation is presented. Following optimization of DMS peptide separation conditions, we examined next the feasibility of a new analytical platform which uses direct sample infusion with nanoESI-DMS-MS for ultrarapid analyte quantitation. Quantitation of a selected peptide from a semicomplex peptide mixture is presented. Initial feasibility results with this new approach demonstrate good accuracy and reproducibility, as well as an absolute mass sensitivity of 6.8 amol and a minimum dynamic range of 2500 for the peptide of interest. This report offers a first look at utilizing nanoESI-DMS-MS to create an ultrarapid (under 5 s) quantitative analysis platform and its potential in the high-throughput arena. Each ion separation technique, DMS and MS, offers orthogonal ion separation to one another, enhancing the overall specificity for this quantitative approach.

Threshold Lesion Temperatures in Argon Laser-Irradiated Rabbit Eyes (1975)

The purpose of this research was to measure threshold temperatures corresponding to the formation of minimum ophthalmoscopically visible lesions induced in rabbit ocular fundi by a 10-s exposure from an argon c. w. laser (4880 Å). The backside of the eye was surgically exposed and a specially designed microthermocouple with a 20-micron dia tip was inserted into the pigment epithelium to measure temperature rises. The mean threshold temperature for 30 measurements in 13 rabbits was 54° C and the standard deviation was 3° C. System error was estimated at 5 percent of temperature rise, or slightly less than ±1/2° C.
Deadline-constrained transmission scheduling and data evacuation in WirelessHART networks (2009)

Real-time data delivery is a critical issue in WirelessHART networks. This paper develops a novel mathematical programming framework for joint routing and link scheduling of deadline-constrained traffic in WirelessHART networks. The general framework explores dynamic network flows in a time-expanded graph model and can provide flexible solutions for a variety of real-time data delivery problems. Data evacuation, an important communication paradigm in WirelessHART networks, is a special case of this general framework. We establish the lower bound on evacuation time for line, multi-line and binary tree networks. Moreover, we design a novel scheduling algorithm for data evacuation in binary tree networks, and prove that this scheduling algorithm always achieves the lower bound on evacuation time. We evaluate our scheduling algorithm through numerical simulations, and the results verify that our algorithm minimizes the evacuation time with the least number of channels.

Craniofacial abnormalities in mice carrying a dominant interference mutation in type X collagen (1997)

Type X collagen is a short, non-fibril forming collagen restricted to hypertrophic cartilage, and has been hypothesized to play a role in endochondral ossification. The purpose of the study was to investigate the consequences resulting from the interference of type X collagen function on the growth and development of the craniofacial skeleton through analysis of transgenic mice with a dominant interference mutation for type X collagen. The craniofacial tissues of 21-day-old transgenic mice were examined by: cephalometric and radiographic densitometry analyses, conventional histology, and immunohistochemistry using antibodies specific for either endogenous mouse type X collagen or the transgene product. Genotypically positive mutant mice showed moderate but statistically significant craniofacial skeletal abnormalities, including the underdevelopment of the chondrocranium and mandible, but no cleft palate. Mean radiographic optical densities of the mutant condylar cartilage and the subchondylar areas were 32% less than the corresponding areas of normal mandibles, while mean radiographic optical density measured at the incisor tooth point remained constant. Histologically, transgene-positive mice revealed compressed hypertrophic cartilage zones and reduced trabeculae in both the mandibular condyle and the synchondroses of the chondrocranium. In the normal condyle, mouse type X collagen was localized by the monospecific antibody against a synthetic rat type X collagen NC1 peptide throughout the hypertrophic cartilage layer; in the mutant condyle, immunoreactivity to endogenous type X collagen was only seen sporadically. The truncated type X collagen transgene product, identified with the monoclonal antibody against an epitope within the chick type X collagen NC2 domain, persisted in the lower hypertrophic cartilage layer and the primary spongiosa, rather than being removed by subsequent endochondral ossification. The data suggested that the expression of the chick type X collagen transgene product was strongly associated with the craniofacial skeletal abnormalities that were distinct from other cartilage-related phenotypes.
How much can we mine from a mouseclick? Data Analytics on VLE Access Data (2014)

A catchphrase of the modern era is that we live in a data-driven society, but what does that actually mean? It means that decisions made in so many parts of our society are not now driven by planning, or logic, or reasoning, but are driven by statistics and patterns derived from raw data. Insights into consumer behaviour, transport, healthcare, entertainment, sports, the stock market, and many more, all are shifting to a model of operation where data, information derived from sensors or from purchasing transactions or from the movement of people or from whatever source, are the drivers for decision-making. So what about data-driven education? Predictive data analytics is a form of data science where historical data from some activity can be used to predict future activity. In this presentation I describe work on-going at Dublin City University where we are mining past student engagement with a virtual learning environment, to predict behaviour and outcomes for current students. I will outline the kinds of insights that can be derived from just a single mouseclick and how that can used as input into incentivised interaction with educational content, almost gamifying the interaction. Concrete examples of the work we are undertaking in Dublin will be used to illustrate the presentation which may just be taking us close to a form of data-driven education.
Read range limitation in IF-based far-field RFID using ASK backscatter modulation (2009)

A model is proposed to describe the fundamental read range limitation due to the local oscillator phase noise in the reader, in IF-based, far-field RFID systems using amplitude-shift keying backscatter modulation. The relation between the system parameters (such as the data transfer rate) and the read range is discussed. The model is validated by measurements done on two different laboratory tag-reader systems.
Delivery of grasses with high levels of unsaturated, protected fatty acids (2008)

Our goal is to increase the metabolisable energy of forage species (such as Lolium perenne, perennial ryegrass) via accumulation of lipids in the leaves, and further improve upon this by the delivery of polyunsaturated fatty acids whilst maintaining a low input agricultural system. Keywords: lipid protection, triacylglyceride, DGAT, oleosin, biohydrogenation
Limited feedback scheme for massive MIMO in mobile multiuser FDD systems (2015)

Massive multiple input multiple output is a promising technology to keep up with the explosive demand of wireless data traffic. The benefits of having a large number of antennas, however, depend on the availability of channel state information (CSI), especially at the transmitter. In frequency division duplex systems, this CSI has to be sent back via the uplink channel, hence incurring a large overhead and degrading the spectral efficiency. Mobility of the users and the large number of antennas exacerbate the problem with frequent tracking of the many timevarying CSI coefficients. This paper presents one approach to address this issue. By tracking only the principal components of the channel gain, and exploiting the wide-sense stationarity of the channel, the amount of required feedback can be reduced significantly. Simulation study shows that the proposed technique is able to achieve high sum-rate with good tracking capability using only limited feedback.
CHiRPS: a general-area parallel multilayer routing system (1995)

A new, highly parallel model for concurrent multilayer routing, called CHiRPS (Configurable Highly Routable Parallel System), is presented. The nucleus of CHiRPS is a very flexible pathfinder that can be easily configured, even in the presence of obstacles, to generate various commonly used pattern-based routes, such as Steiner trees with single trunk, comb trees, contour-based routes, etc., that span multiple layers simultaneously. The authors employ the concept of a total grid-graph to capture the state of the routing region. The main steps of the pathfinder are based on new parallel algorithms for cycle detection, cycle elimination and tree reduction. The proposed algorithms scale well with increased problem sizes since they require only O(log N) time when given a grid-graph with up to N2 nodes. As such, they are good candidates for massively data-parallel machines.
ULTRAFINE <font>ZnO</font> NANOWIRES GROWN ON PATTERNABLE <font>Pd</font> CATALYST AND THEIR SOURCE-ENERGY DEPENDENT PHOTOLUMINESCENCE (2011)

Patterned arrays of ZnO nanostructures have been obtained from a solution based method using Pd nanoparticles as catalyst. The catalyst nanoparticles were patterned using a direct-write e-beam lithography process. Within 10 minutes in an aqueous solution of zinc nitrate and triethyamine borane at 80°C, fine nanowires of ZnO with diameter around 10 nm were produced on patterned Pd nanoparticles. Longer duration in the precursor solution led to formation of ZnO fibril-like structures. Photoluminescence measurements revealed that the nanostructures exhibited a blue shift for the emission peak at 390 nm, when the excitation energy was increased, unlike bulk ZnO . This is attributed to the discrete defect states present in confined nanostructures.
Numerical Simulation of High Electron Mobility Transistors based on the Spectral Element Method (2016)

The spectral element method (SEM) is implemented for the numerical simulation of high electron mobility transistors (HEMTs) through a selfconsistent solution of the Schrodinger-Poisson equations. The electron conduction band structure and electron density distribution are calculated and plotted, and results compared to those based on methods utilizing a finite-difference approach. Simulation accuracy and efficiency are analyzed and compared with traditional finite difference method (FDM). DC current-voltage (I-V) characteristics for the HEMT structure are simulated, based on a quasi-2D current model. The SEM approach offers advantages in speed and efficiency over FDM, while yielding results which conform well to reported experimental results. These advantages are particularly important for compound heterojunction devices with complex material profiles, for which FDM methods may be inefficient and computationally slow.
Microwave breakdown in output multiplexer filters (2002)

A theoretical investigation is made of microwave breakdown in output multiplexer filters. The effects of the electrical breakdown cause irreversible damage to the device and so the power level, which generates such a phenomenon, must be predicted. This study needs a pluridisciplinary approach with a combination of three fields of the science: the electromagnetism, the thermic and the plasma physics.
Intrasite Scheduling for Interference Avoidance in LTE (2011)

A novel method of intra-site interference avoidance is developed that seeks a balance between intra-site resource orthogonality and independent frequency selectivity. The method is compared against existing time and frequency selective scheduling approaches, as well as a static priority based interference avoidance scheme. The intra-site method promoted obtains better total and percentile throughputs compared to the schemes examined, and demonstrates the benefits that access to intra-site scheduling information can realise. Statistically robust results are obtained through system level simulations of LTE in the downlink direction only.
A Feed-Forward Control Based Method to Reduce the Settling Time of Phase-Locked Loops for Frequency Ramp Synthesis (2019)

Phase-locked loops (PPLs) are used as ultra-wideband and precise frequency synthesizers for frequency modulated continuous wave signals. Within the settling time the output frequency is not the desired multiple of the input frequency. In case of frequency ramps, the settling time reduces the usable bandwidth of the system or the maximal possible measuring rate. To reduce the settling time we present a feed-forward control (FFC) based method, which adapts the modulation of either the reference frequency or the division ratio of the frequency divider. Two noise-optimized microwave PLLs are optimized using the FFC based method. Simulation and measurement results are compared with each other and demonstrate the performance of the method. For an X-band PLL, the settling time is reduced by a factor of 15.44 to 306 ns, and for a V-band PLL by a factor of 2.3 to 228 ns.
Induction of Round Heart Disease in Turkey Poults by Feed Texture (2005)

Incidence of round heart disease was prevalent in starting turkey poults in studies at ou r experimental facility. Two experiments were conducted to evaluate two dietary factors that may have contributed to increased susceptibility of poults to round heart disease. Experiment 1 consisted of 4 dietary treatments in which dietary chlorine ranged from 0.17 to 0.29% as a result of salt addition, but dietary sodium was maintained at 0.17%. Experiment 2 consisted of poults fed the same pre-starter (0-3 wk of age) and starter (3-6 wk of age) feeds. The diets were fed either in a mash or crumbled form with or without a post- hatch supplement the first day of the experiment. Poults were placed approximately 4 hr after departure from the hatchery. There was no evidence of round heart disease mortality in Experiment 1. According to body weight data, the dietary chlorine requirement was estimated to be 0.21% when adequate dietary sodium and potassium are fed. Mortality was increased in Experiment 2 due to round heart disease when crumbles were fed. The addition of a post-hatch supplement did not affect growth or mortality. The results of these studies indicate that feeding crumbles to poults increased round heart disease incidence starting at 6 days of age due to faster growth rate.

Thermal Testing of the Heatshield for Extreme Entry Environment Technology (HEEET) TPS (2015)

The testing of a thermal protection system (TPS) in multiple arc jets and laser facilities is critical not only to determine the ability of a material to withstand the harsh aerothermal environments but is also required to collect relevant data that allows construction of a thermal response model of the TPS for flight design. The present talk provides an overview of recent arcjet testing of the HEEET material, one of the families of materials from the 3D Woven TPS program, being developed under NASAs Heatshield for Extreme Entry Environment Technology (HEEET) project.
A novel<i>Vibrio</i>beta-glucosidase (LamN) that hydrolyzes the algal storage polysaccharide laminarin (2015)

The metabolic versatility, tractability and rapid growth potential of the Vibrio spp. have made them increasingly attractive systems for investigating carbon cycling in the marine environment. In this study, an in silico subtractive proteomic strategy was used to identify a novel 101 kDa GH3 family β-glucosidase (LamN) that was found in bioluminescent Vibrio campbellii strains capable of utilizing the algal storage glucan laminarin. A heterologous overexpression system verified the sequence-predicted function of LamN as it enabled the growth of Escherichia coli on laminarin as a sole carbon source. Quantitative reverse transcription PCR analyses revealed that V. campbellii grown on laminarin demonstrated a 4- to 314-fold induction of lamN gene expression when compared to the same strains grown on glucose or glycerol. Corresponding tandem mass spectrometric analyses detected LamN protein expression only in cells grown on laminarin. Heterologous expression, purification and biochemical characterization identified LamN as a heat stable laminarinase with β-1,3, β-1,4 and β-1,6 glucosidase activity. Collectively, these data identify an enzyme that may allow V. campbellii to exploit some of the most abundant polysaccharides associated with deteriorating phytoplankton blooms and provide support for the potential involvement of V. campbellii in the formation of bioluminescent milky seas.
Laser generation of exotic cluster compounds (1986)

Revivals and entanglement from initially entangled mixed states of a damped Jaynes-Cummings model (2003)

An exact density matrix of a phase-damped Jaynes-Cummings model (JCM) with entangled Bell-like initial states formed from a model two-state atom and sets of adjacent photon number states of a single-mode radiation field is presented. The entanglement of the initial states and the subsequent time evolution is assured by finding a positive lower bound on the concurrence of local $2\ifmmode\times\else\texttimes\fi{}2$ projections of the full $2\ifmmode\times\else\texttimes\fi{}\ensuremath{\infty}$ JCM density matrix. It is found that the time evolution of the lower bound of the concurrence systematically captures the corresponding collapse and revival features in atomic inversion, relative entropies of atomic and radiation, mutual entropy, and quantum deficit. The atom and radiation subsystems exhibit alternating sets of collapses and revivals in a complementary fashion due to the initially mixed states of the atom and radiation employed here. This is in contrast with the result obtained when the initial state of the dissipationless system is a factored pure state of the atom and radiation, where the atomic and radiation entropies are necessarily the same. The magnitudes of the entanglement lower bound and the atomic and radiation revivals become larger as both the magnitude and phase of the Bell-like initial state contribution increase. The time evolution of the entropy difference of the total system and that of the radiation subsystem exhibit negative regions called ``supercorrelated'' states which do not appear in the atomic subsystem. Entangled initial states are found to enhance this supercorrelated feature. Finally, the effect of phase damping is to randomize both the subsystems for asymptotically long times. It may be feasible to experimentally investigate the results presented here using the Rabi oscillation methods of microwave and optical cavity quantum electrodynamics since pure photon number states have recently been produced and observed.
