Combinatorics (1994)

Combinatorics is a subject of increasing importance, owing to its links with computer science, statistics and algebra. This is a textbook aimed at second-year undergraduates to beginning graduates. It stresses common techniques (such as generating functions and recursive construction) which underlie the great variety of subject matter and also stresses the fact that a constructive or algorithmic proof is more valuable than an existence proof. The book is divided into two parts, the second at a higher level and with a wider range than the first. Historical notes are included which give a wider perspective on the subject. More advanced topics are given as projects and there are a number of exercises, some with solutions given.
Improving decoding tube performance for the UWPET time of flight detector modules (2003)

The UWPET (ultraviolet positron emission tomograph) (a modified SP-3000 time-of-flight system) utilizes detector modules with eight BaF/sub 2/ crystals coupled to five photomultiplier tubes. Although previous changes have improved module performance, further tests have been conducted in an attempt to increase both the inner/outer crystal decoding efficiency and the long-term optical coupling stability. It has been verified that KE103 compound provides the same UV light transmission as the Viscascil 600000 normally used. KE103 is generally considered the more mechanically stable project. Attempts were made to improve the energy resolution and peak position by increasing the amount of light reaching the decoding tube through a light-sharing technique and by reducing electronic noise associated with the decoding tube. At this time it appears that the initial configuration, developed by PETT electronics, is the most effective.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Discovering Behavioral Patterns Using Conversational Technology for In-Home Health and Well-Being Monitoring (2023)

Advancements in conversational AI have created unparalleled opportunities to promote the independence and well-being of older adults, including people living with dementia (PLWD). However, conversational agents have yet to demonstrate a direct impact in supporting target populations at home, particularly with long-term user benefits and clinical utility. We introduce an infrastructure fusing in-home activity data captured by Internet of Things (IoT) technologies with voice interactions using conversational technology (Amazon Alexa). We collect 3103 person-days of voice and environmental data across 14 households with PLWD to identify behavioural patterns. Interactions include an automated well-being questionnaire and 10 topics of interest, identified using topic modelling. Although a significant decrease in conversational technology usage was observed after the novelty phase across the cohort, steady state data acquisition for modelling was sustained. We analyse household activity sequences preceding or following Alexa interactions through pairwise similarity and clustering methods. Our analysis demonstrates the capability to identify individual behavioural patterns, changes in those patterns and the corresponding time periods. We further report that households with PLWD continued using Alexa following clinical events (e.g., hospitalisations), which offers a compelling opportunity for proactive health and well-being data gathering related to medical changes. Results demonstrate the promise of conversational AI in digital health monitoring for ageing and dementia support and offer a basis for tracking health and deterioration as indicated by household activity, which can inform healthcare professionals and relevant stakeholders for timely interventions. Future work will use the bespoke behavioural patterns extracted to create more personalised AI conversations.
Submap-based SLAM for road markings (2015)

Coherent road maps are a prerequisite for autonomous navigation. In case of an unknown environment, grid map and SLAM techniques are widely used. This paper takes a novel approach to vision based mapping of road markings by registration of local occupancy gridmaps for map stitching. We show that with reasonably accurate ego motion measurements, seamless global maps can be constructed from local grid maps. The approach is evaluated on real world data obtained from an autonomous model racing car.
James Webb Space Telescope: the road to first science observations (Presentation Video) (2014)

The James Webb Space Telescope (JWST) is a large aperture, infrared telescope planned for launch in 2018. JWST is a facility observatory that will address a broad range of science goals covering four major themes: First light and Re- Ionization, the Assembly of Galaxies, the Birth of Stars and Protoplanetary Systems, and Planetary Systems and the Origins of Life. JWST embodies several major technical challenges. With a 6.5 meter diameter mirror it will be the largest space telescope ever flown. It is the first cryogenic telescope to incorporate passive cooling, achieved by means of a large sunshade, to reach its ~40 K operating temperature. Due to the size of the Observatory, it must be stowed for launch, and then deployed to its operational configuration on its way to an orbit around the second Lagrange point. JWST is well on its way from drawing board to sky. Much of the flight hardware is already built and tested at the sub-system level. In this talk we will focus on the remaining tasks on the road to JWST’s first science observations on the sky. Prior to the launch, the remaining work to integrate the observatory elements centers around four major activities: • Cryo-optical testing of the instrument complement • Cryo-optical testing of the assembled telescope and instrument complement; • Integration of the observatory • Full-scale testing of the observatory deployments. We will discuss the design and philosophy underlying the cryo-optical test program for the Observatory. Cryo-optical testing begins with the instrument complement at the Goddard Space Flight Center, and finishes with an end-to-end test of the assembled telescope in the world’s largest cryogenic vacuum chamber at the Johnson Space Flight Center. In the context of a detailed overview of JWST’s deployment steps after launch, we will describe the final stages of Observatory integration and the testing to verify these deployments, ready for launch. Finally, we will discuss the post-launch timeline to transition the stowed Observatory to the start of science operations.
Wirelessly interrogable acoustic sensors (2003)

A survey is given on wirelessly interrogable passive surface acoustic wave (SAW) sensors. Three types of SAW devices are discussed and classified as to their function in remote sensing of measurands (e.g. temperature, mechanical strain, stress ec.): Type I: transit time sensors, type II: SAW delay lines for wireless evaluation of remote conventional sensors and type III: SAW resonators. Efficient and successfully proven methods of wireless interrogation and evaluation are presented and some applications briefly mentioned.
A Phantom Study of the Geometric Accuracy of Computed Tomographic and Magnetic Resonance Imaging Stereotactic Localization with the Leksell Stereotactic System (2001)

The accuracy of target localization for most intracranial lesions during stereotactic radiosurgery can be achieved within the size of a voxel, especially by using the Siemens MRI scanner at current specifications and with a new software patch. However, caution is warranted when imaging peripheral lesions, where the distortion is greatest.
GreenICN Project: Architecture and Applications of Green Information Centric Networking (2016)

As a research project supported jointly by the National Institute of Information and Communications Technology (NICT) in Japan and the European Commission under its 7th Framework Program, the GreenICN Project has been in operation from 2013 to 2016. The GreenICN project focused on two typical application scenarios, one a disaster scenario and the other a video delivery scenario. The disaster scenario assumed a situation of limited resources, and the video delivery scenario assumed a situation of large-scale content delivery. In both situations, the project challenged to provide “green”, i.e. energy-efficient, content delivery mechanism. For this goal, we designed an energy consumption model to lay out energy reduction policies. For the achievement of the policies, we improved ICN architecture, for example a name-based publish/subscribe mechanism, an effective cache management policy,energy-efficient security scheme and a new energy API. This paper provides a summary of our achievements and descriptions of some outcome.
Engineered measles virus as a novel oncolytic therapy against prostate cancer (2008)

MV-CEA has potent antitumor activity against prostate cancer cell lines and xenografts. Viral gene expression during treatment can be determined by monitoring of CEA levels in the serum; the latter could allow dose optimization and tailoring of individualized treatment protocols.
Mutations in <i>LRRK2</i> as a Cause of Parkinson’s Disease (2007)

Mutations in leucine-rich repeat kinase 2 (LRRK2) are the most common known cause of late-onset Parkinson's disease (PD). Clinical and pathological studies have demonstrated that in the majority of cases LRRK2 mutations lead to PD with classical clinical and pathological features. However, in some patients the pathological features can be distinct and/or more extensive than typically seen in PD. Collectively, these findings provide important clues into the mechanisms by which LRRK2 mutations can lead to demise of dopaminergic neurons. The understanding of LRRK2 protein function and its gene regulation and the consequences of mutations are still at their infancy, but scientific findings are progressing at a rapid pace. Although more detailed information on LRRK2 is still needed in the quest for therapeutic intervention that could halt or slow the progression of disease, here we summarize the current information on the biological and pathological properties of LRRK2.
Appraising California Zinfandel Exposure to Wildfire Smoke Using Natural Product Phenolic Diglycoside Biomarkers (2022)

Zinfandel grapes are ubiquitous in California and its wine quality could be negatively impacted from wildfire smoke. Thus, the occurrence of fires prior to grape harvest presents a persistent problem to both viticulture and enology processes. This is the first broad study on Zinfandel to investigate wine quality defects produced by natural wildfires. The project, guided by UHPLC separations and MS<sup>2</sup> multiple reaction monitoring, involved measuring natural product phenolic diglycosides (PDs) bioaccumulated in grapes, and expands outcomes published in 2022 by our team (called the Santa Cruz Campaign, SCC). The plan was implemented by exploiting a panel of six marker PDs <b>1</b>-<b>6</b> and their deuterated analogues. Examined in the study were 24 different Zinfandel wines obtained from 2016 to 2021 vintages of nine different American Viticulture Areas (AVAs) that were also within five of the eight California Zinfandel viticulture zones. The goal was to extend understanding on PD variations using patterns that possibly change as a function of appellation and fire intensity. Preliminary data was obtained to examine the relative amounts of PDs localized in berry skin versus pulp. The baseline of <15 ppb was proposed by surveying 18 distinct unsmoked Zinfandel wines. It was proposed to estimate the smoke impact on other Zinfandel wines by using seven PD ppb concentrations categories. A pilot study was also launched to assess conclusions by comparing ppb-based ratings versus sensory evaluation quality estimates. General findings presented herein should provide an important foundation to build understanding of using PD patterns to forecast possible Zinfandel wine wildfire damage.

Left Bundle Branch Pacing: Bench to Bedside and beyond (2020)

Cardiac pacing is the only effective therapy for patients with symptomatic brady-arrhythmia. Traditional right ventricular apical pacing causes electrical and mechanical dyssynchrony resulting in left ventricular dysfunction, recurrent heart failure and atrial arrhythmias. Physiological pacing activates the normal cardiac conduction thereby providing synchronized contraction of ventricles. Though His bundle pacing (HBP) acts as an ideal physiological pacing modality, it is technically challenging and associated with troubleshooting issues during follow up. Left bundle branch pacing (LBBP) has been suggested as an effective alternative to overcome the limitations of HBP as it provides low and stable pacing threshold, lead stability and correction of distal conduction system disease. This paper will focus on the implantation technique, troubleshooting, clinical implications and a review of published literature of LBBP

Quantum beating in Rb at18.3THz(608cm−1)detected by parametric six-wave mixing and sum-frequency generation inLiIO3 (2007)

Axially phase-matched parametric six-wave mixing (PSWM) has been observed in Rb vapor by two-photon excitation of the atom $(5s\ensuremath{\rightarrow}\ensuremath{\rightarrow}7s,5d)$ with $\ensuremath{\sim}150\phantom{\rule{0.3em}{0ex}}\mathrm{fs}$ pulses, centered at $\ensuremath{\lambda}\ensuremath{\sim}769\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$ and generated by a $\mathrm{Ti}:{\mathrm{Al}}_{2}{\mathrm{O}}_{3}$ laser system. For a peak laser pulse intensity of $30\phantom{\rule{0.3em}{0ex}}\mathrm{GW}\phantom{\rule{0.2em}{0ex}}{\mathrm{cm}}^{\ensuremath{-}2}$, PSWM is observed for Rb number densities $([\mathrm{Rb}])&gt;2.5\ifmmode\times\else\texttimes\fi{}{10}^{15}\phantom{\rule{0.3em}{0ex}}{\mathrm{cm}}^{\ensuremath{-}3}$ whereas, for $[\mathrm{Rb}]=2.2\ifmmode\times\else\texttimes\fi{}{10}^{16}\phantom{\rule{0.3em}{0ex}}{\mathrm{cm}}^{\ensuremath{-}3}$, the PSWM process is detectable for pump intensities above $\ensuremath{\sim}3\phantom{\rule{0.3em}{0ex}}\mathrm{GW}\phantom{\rule{0.2em}{0ex}}{\mathrm{cm}}^{\ensuremath{-}2}$. Upconversion of the $1.367\phantom{\rule{0.3em}{0ex}}\mathrm{\ensuremath{\mu}}\mathrm{m}$ and $1.323\phantom{\rule{0.3em}{0ex}}\mathrm{\ensuremath{\mu}}\mathrm{m}$ signal waves into the visible $(\ensuremath{\lambda}\ensuremath{\sim}494\phantom{\rule{0.3em}{0ex}}\mathrm{nm})$ has been accomplished by sum frequency generation in ${\mathrm{LiIO}}_{3}$, and quantum beating in Rb at $18.3\phantom{\rule{0.3em}{0ex}}\mathrm{THz}$ $(\ensuremath{\sim}608\phantom{\rule{0.3em}{0ex}}{\mathrm{cm}}^{\ensuremath{-}1})$ has been observed by monitoring the upconverted signal wave intensity produced in pump-probe experiments. These results broaden the scope of the wave packet detection scheme reported by Tran et al. [Opt. Lett. 23, 70 (1998)] in that a variety of coherent nonlinear optical processes $({\ensuremath{\chi}}^{(3)},{\ensuremath{\chi}}^{(5)},\dots{})$ appear to be suitable for observing the amplitude and phase of atomic (or molecular) wave packets.
Secondary ion mass spectrometry round-robin study of relative sensitivity factors in gallium arsenide (1998)

Round-robin studies on relative sensitivity factors (RSFs) in secondary ion mass spectrometry (SIMS) were conducted using bulk GaAs samples uniformly doped with various impurity elements. A total of 31 laboratories participated in two round-robins. More than 30 sets of relative ion intensities were obtained for B, Si, Cr, Mn, Fe, Cu, Zn, In and Te in GaAs. The RSFs for both positive and negative ions were derived for several types of SIMS instruments. The effect of primary ion incident angle was examined using quadrupole-based instruments and found to be the determining factor of the instrumental dependence of RSF. © 1998 John Wiley & Sons, Ltd.
A Five-Year Core for a Small Modular Light Water Reactor (2011)

To address the energy needs of developing countries and remote communities, Oregon State University has proposed the Multi-Application Small Light Water Reactor (MASLWR) design. This design uses 8% enriched fuel to achieve five years of operation without refueling. The specific operational conditions (lower pressure and temperature of fuel and coolant), increased enrichment of fuel, and extensive use of gadolinium burnable absorbers lead to significantly different neutron physics compared to conventional pressurized water reactors. In particular, spectrum hardening due to increased thermal neutron absorption, changes in kinetic parameters due to the isotopic content of the fresh and irradiated fuel, and fuel and control rod shadowing by burnable absorbers are consequences of the design requirements. Enhanced neutron leakage from the small MASLWR core also adds complexity. Neutron reflectors and a unique fuel-loading pattern compensate the pronounced axial and radial gradients of the neutron flux and power generation.This paper discusses the neutron physics and thermal-hydraulic issues of the core design for a small reactor with increased fuel enrichment and natural circulation of the coolant. The paper describes three evolutionary steps of the MASLWR core design process and discusses core parameters, advantages, disadvantages, and design limitations as they appeared during the core design feasibility study. The paper demonstrates the feasibility of the core design for five effective years of nonrefueled operation with 8.0% enriched UO2 fuel.
Mechanism of Crosslinking of Proteins by Glutaraldehyde IV:In VitroandIn VivoStability of a Crosslinked Collagen Matrix (1990)

The use of native or reconstituted collagen as a bioprothesis for tissue augmentation requires the introduction of exogenous synthetic crosslinks. The degree of crosslinking determines the rate of resorption or replacement of the implanted materials by the host. Since biophysical and chemical methods to quantify these crosslinks have in general been difficult to evaluate, we have developed in vitro enzymatic approaches which enable us to correlate the degree of crosslinking with the rates of enzymatic degradation. When the number of stable crosslinks formed is large it is essential to partially unfold the collagen fibrils by heating or by exposure to denaturing agents to enhance their susceptibility to hydrolysis. In the present study we demonstrate that increasing the number of reactive amino groups on collagen by coupling 1,6-diaminohexane to carboxyl groups using a water soluble carbodiimide can significantly enhance the number of crosslinks introduced by glutaraldehyde. We also show that the enzymatic method developed correlates well with the biodegradation of radiolabeled crosslinked collagenous tissues implanted subcutaneously in rats.
Low temperature flow lithography (2018)

Flow lithography (FL) is a microfluidic technique distinguished for its ability to produce hydrogel microparticles of various geometrical and chemical designs. While FL is typically performed in room temperature, this paper reports a new technique called low temperature flow lithography that uses low synthesis temperature to increase the degree of polymerization of microparticles without compromising other aspects of flow lithography. We suggest that decreased oxygen diffusivity in low temperature is responsible for the increase in polymerization. Microparticles that exhibit a higher degree of polymerization display a more developed polymer network, ultimately resulting in a more defined morphology, higher incorporation of materials of interest, and improved functional performance. This work demonstrates the increase in the degree of polymerization by examining the temperature effect on both the physical and chemical structures of particles. We show applications of this technique in synthesizing thin microparticles and enhancing microparticle-based detection of microRNA. Low temperature FL offers a simple and easy method of improving the degree of polymerization, which can be implemented in a wide range of FL applications.

<310> Single-Crystal LaB6 as Thermal Field Emitter for Electron Microscope (1990)

Thermal field emission (T.F.E.) properties of single crystal LaB 6 -tips has been investigated by observing emission patterns. Applying field evaporation technique we succeeded to get the clean pattern consisting of &lt;310&gt; spots with very good reproducibility. This investigation has led to conclusion;, the &lt;310&gt; spot is promising electron source of high brightness provided that the tip is operated at tip temperature∽ 1000-1050°C in vacuum of 10 −9 Torr region. As a preliminary experiment of brightness-measurement, we mounted the &lt;310&gt; LaB 6 -tip in a commercial type TEM, JEM-100CX-FEG, attached with an electron gun system for T.F.E. of &lt;100&gt; W-tip, being operated at 10 −9 Torr region without Schottky shield electrode. The LaB 6 -tip, however, can not be operated without the Schottky shield because thermionic emission (T.E.) from the LaB 6 -tip is considerably high even though the tip is operated at lower than ∽1000 °C. In the present experiment, therefore, we manufactured a Schottky shield electrode as shown in Fig.l and performed the measurement of brightness by setting the Schottky shield electrode, applied the same voltage as the tip since the electron gun system has no extra feed-throughs for bias-voltage.
