Preparation and Properties of New Regenerated Cellulose Fibers (2003)

New regenerated cellulose fibers are prepared from solution (chemical cellulose con tents, 3, 4.5, 6, and 9 wt%) using N-methylmorpholine-N-oxide (NMMO)/water (87/13 wt%) as a solvent by dry-wet spinning at a winding speed of 20-100 m/min. The chemical cellulose (97% α-cellulose content, 918 DPw, 98% JIS whiteness) used for this study is prepared from ascidian tunicates by a modified pulping process described in our previous work. The effects of cellulose content and spinning speed on the structure and mechanical properties of fibers are investigated. As the cellulose content increases, the birefringence, crystallinity, and initial tensile modulus of the fibers increase significantly. While the tenacity of the fibers increases with increasing cellulose content up to 6 wt%, there is a great decrease in the tenacity at 9 wt%. That decrease is due to fiber defects. Mechanical properties increase with increasing winding speed. The regenerated cellulosic fibers prepared in this study have a higher ratio of wet strength to dry strength compared to regenerated cellulose fibers produced all over the world.
Research and Development on Knowledge Bases Systems at ICOT (1986)

This paper describes ICOT’s research and development activities on knowledge base systems. Our approach is to investigate knowledge base systems from the viewpoint of logic programming. We have defined several models on the bases of which knowledge base systems will be developed step by step. Two types of knowledge base management software system models are discussed. One is a model combining a logic programming system and a database management software system. The other is an integrated model. Pilot, distributed, and parallel-knowledge base machines models are also discussed. Intelligent interface Intelligent programming
RNA-Binding and Capping Activities of Proteins in Rotavirus Open Cores (1999)

Guanylyltransferases are members of the nucleotidyltransferase family and function in mRNA capping by transferring GMP to the phosphate end of nascent RNAs. Although numerous guanylyltransferases have been identified, studies which define the nature of the interaction between the capping enzymes of any origin and their RNA substrates have been limited. Here, we have characterized the RNA-binding activity of VP3, a minor protein component of the core of rotavirions that has been proposed to function as the viral guanylyltransferase and to direct the capping of the 11 transcripts synthesized from the segmented double-stranded RNA (dsRNA) genome of these viruses. Gel shift analysis performed with disrupted (open) virion-derived cores and virus-specific RNA probes showed that VP3 has affinity for single-stranded RNA (ssRNA) but not for dsRNA. While the ssRNA-binding activity of VP3 was found to be sequence independent, the protein does exhibit preferential affinity for uncapped over capped RNA. Like the RNA-binding activity, RNA capping assays performed with open cores indicates that the guanylyltransferase activity of VP3 is nonspecific and is able to cap RNAs initiating with a G or an A residue. These data establish that all three rotavirus core proteins, VP1, the RNA polymerase; VP2, the core capsid protein; and VP3, the guanylyltransferase, have affinity for RNA but that only in the case of the RNA polymerase is the affinity sequence specific.
Localization of Epstein-Barr virus-encoded small RNAs by in situ hybridization. (1986)

Human B lymphocytes latently infected with Epstein-Barr virus (EBV) synthesize two low molecular weight RNAs designated EBER 1 and 2. Using an in situ hybridization technique we have localized EBER 1 and 2 within the nucleus of single EBV-harboring B lymphocytes from established and recently transformed cell lines. As controls, the locations of the small nuclear RNA, U1, and the small cytoplasmic RNA, 7SL, were examined in HeLa and EBV-harboring cells. Because of possible functional similarities between EBERs and the adenovirus-associated (VA) RNAs, VAI was also localized; it appeared to be in the nucleus and cytoplasm, implying that VAI may have a different role than that of the nuclear-localized EBERs.
Reactive blends of gelatinized starch and polycaprolactone‐<i>g</i>‐glycidyl methacrylate (2001)

Abstract Blends of the modified polycaprolactone (PCL) and the gelatinized starch with glycerin were prepared. The modified PCL, PCL‐ g ‐glycidyl methacrylate (GPCL), was synthesized by melt reaction of PCL and glycidyl methacrylate (GMA) in the presence of benzoyl peroxide (BPO) in a Brabender mixer. The size of the dispersed starch in the GPCL matrix was found to be smaller than that in the PCL matrix. As the relative content of the GMA groups in the GPCL increases, the elongation at break of the blend showed the highest value at a grafted GMA content of 4.2 wt %. With the increase of the glycerin content in the starch, an abrupt change of the mechanical properties of the blend were observed between 40 and 50 wt % glycerin content based on the starch weight. © 2001 John Wiley & Sons, Inc.

Establishing the diagnostic validity of premenstrual dysphoric disorder using rasch analysis. (1997)

Premenstrual Dysphoric Disorder (PMDD) has remained in appendices of the last two editions of The Diagnostic and Statistical Manual of Mental Disorders due to lack of empirical study. Items included in its set of research criteria are considered tentative pending evidence of diagnostic validity. The present study attempts to establish the construct validity of the PMDD criteria using the Rasch method to analyze the validity of individual items as contributors to the diagnosis, in contrast to the usual but less precise approach of using an external validator to establish the diagnostic utility of psychiatric conditions. Analysis of which items best differentiate participants with and without PMDD provides an idea of the relative ability of these items to distinguish PMDD. It is recommended that the areas of anger/irritability, depressed mood, and problems in interpersonal functioning be expanded in further studies and corresponding items added to symptom checklists.
Development Flow for On-Line Core Self-Test of Automotive Microcontrollers (2015)

Software-Based Self-Test is an effective methodology for devising the online testing of Systems-on-Chip. In the automotive field, a set of test programs to be run during mission mode is also called Core Self-Test library. This paper introduces many new contributions: (1) it illustrates the several issues that need to be taken into account when generating test programs for on-line execution; (2) it proposed an overall development flow based on ordered generation of test programs that is minimizing the computational efforts; (3) it is providing guidelines for allowing the coexistence of the Core Self-Test library with the mission application while guaranteeing execution robustness. The proposed methodology has been experimented on a large industrial case study. The coverage level reached after one year of team work is over 87 percent of stuck-at fault coverage, and execution time is compliant with the ISO26262 specification. Experimental results suggest that alternative approaches may request excessive evaluation time thus making the generation flow unfeasible for large designs.

Especially, the necessity of high pressure bioscience is stressed for further development of this new philosophy to achieve the industrial success.
Corpus-based semantic lexicon induction with Web-based corroboration (2009)

Various techniques have been developed to automatically induce semantic dictionaries from text corpora and from the Web. Our research combines corpus-based semantic lexicon induction with statistics acquired from the Web to improve the accuracy of automatically acquired domain-specific dictionaries. We use a weakly supervised bootstrapping algorithm to induce a semantic lexicon from a text corpus, and then issue Web queries to generate co-occurrence statistics between each lexicon entry and semantically related terms. The Web statistics provide a source of independent evidence to confirm, or disconfirm, that a word belongs to the intended semantic category. We evaluate this approach on 7 semantic categories representing two domains. Our results show that the Web statistics dramatically improve the ranking of lexicon entries, and can also be used to filter incorrect entries.
Smartphone-Based Travel Experience Sampling and Behavior Intervention among Young Adults (2012)

This research project aims to develop a data collection application that enables real-time tracking and reporting of\nthe health-related impacts of travel behavior. Using computing, communication, and sensing capabilities of\nsmartphones, an Android phone application—named UbiActive—was developed to collect real-time travel-related\nphysical activity and psychological well-being data from phone users. The application was tested on multiple\nAndroid phones, among which Nexus S and HTC Magic were found to produce comparable physical activity\noutputs with the commercially available accelerometer.\n\nThe application was further tested in a three-week field study for its viability for real-time data collection\nand behavior intervention against unhealthy travel behavior. Twenty-three young adults were recruited and\nrandomized into intervention and control groups. Both groups were asked to install UbiActive on their phone and\nwear their phone on their right hip during all waking hours for three consecutive weeks. The intervention group\nwas provided information on impacts of their travel behavior on physical activity and psychological well-being.\nNo information was provided to the control group. After the field study, all participants were asked to complete a\nweb-based exit survey that was comprised of questions about their general participation experience and specific\nconcerns about the study design, application, compliance requirements, and privacy issues.\n\nFindings from the field study show that UbiActive has high potential in collecting travel-related physical\nactivity and psychological experience data, but limited effectiveness in behavior intervention. Findings from the\nexit survey provide useful insights into potential improvement areas of the study and the UbiActive application.
Catalytic Hydrotreating of Biomass-Derived Oils (1988)

Pacific Northwest Laboratory (PNL) is investigating the catalytic upgrading of biomass-derived oils to liquid hydrocarbon fuels. Tests have been conducted in a 1-liter, continuous-feed, fixed-bed catalytic reactor at 250-450°C and 2,000 psig. Catalytic upgrading is envisioned as the second stage in a two-stage process to produce hydrocarbon fuels from biomass. Direct thermochemical liquefaction of biomass produces a phenolic oil containing very few hydrocarbons. Hydrotreating these oils can produce nearly pure hydrocarbons, primarily aromatics and naphthenes which would be useful in gasoline blending.

A review is given of co-channel interference in small-cell systems and of the means for its avoidance. Propagation phenomena are described. A table is given for the separation of base stations having both the same channel and the same supervisory tone, for up to 16 cells per block and zero to seven tones. Curves are given versus distance for the probability of interference from one station and from one or more stations in a seven-cell arrangement. Means for avoiding such interference are reviewed.
Recent results from DIII-D and future plans (2002)

Recent DIII-D tokamak experimental results are summarized, new hardware being implemented to carry out the DIII-D 1990s tokamak research program is described, and their implications for engineering designs for next-generation tokamaks, such as ITER (International Thermonuclear Experimental Reactor), are discussed. DIII-D is presently investigating several new and alternative methods to address key ITER design issues: divertor, disruption, and current profile control. DIII-D is also demonstrating improved tokamak performance regimes such as high beta second stability and high confinement such as VH-mode. On a more basic and broader research front, DIII-D is exploring innovative tokamak engineering and physics concepts, solidifying fundamental plasma physics understanding, and demonstrating essential engineering technologies with the goal of developing a safe and environmentally and commercially attractive fusion reactor concept.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Tree Root Automatic Recognition in Ground Penetrating Radar Profiles Based on Randomized Hough Transform (2016)

As a nondestructive geophysical tool, Ground penetrating radar (GPR) has been applied in tree root study in recent years. With increasing amounts of GPR data collected for roots, it is imperative to develop an efficient automatic recognition of roots in GPR images. However, few works have been completed on this topic because of the complexity in root recognition problem. Based on GPR datasets from both controlled and in situ experiments, the randomized Hough transform (RHT) algorithm was evaluated in root object recognition for different center frequencies (400 MHz, 900 MHz, and 2000 MHz) in this paper. Reasonable accuracy was obtained (both a high recognition rate and a low false alarm rate) in these datasets, which shows it is feasible to apply the RHT algorithm for root recognition. Furthermore, we evaluated the influence of root and soil factors on the recognition. We found that the performance of RHT algorithm is mainly affected by root interval length, root orientation, and clutter noise of soil. The recognition results by RHT could be applied for large scale root system distribution study in belowground ecology. Further studies should be conducted to reduce clutter noise and improve the recognition of the complex root reflections.
Frequency estimator to improve short range accuracy in FMCW radar (2015)

Frequency Modulated Continuous Wave (FMCW) radars have been widely used for short and medium range detection. Applications of FMCW radar, where measuring short distances is critical, need to have a high accuracy. In the FMCW radar systems, the received signal is a delayed version of the transmitted signal. The range is calculated by measuring the beat frequency of the received signal. The range resolution of radar is inversely proportional to the transmitting bandwidth of the radar. In order to achieve a better range resolution we need to increase the bandwidth, which has its own limitations. To increase the bin resolution of FFT of the beat signal, the sampling frequency must be increased which increases the system complexity. A frequency estimator is implemented to enhance the accuracy of short range detection in FMCW radar without increasing the bandwidth or sampling frequency of the system. It compensates the error by calculating an offset value to provide fine beat frequency.

SDS-PAGE Analysis of Soluble Proteins in Reconstituted Milk Exposed to Different Heat Treatments (2007)

This paper deals with the investigation of the impact of the heat treatment of reconstituted skim milk conducted at different temperatures, and the adding of demineralized whey on the protein solubility, soluble protein composition and interactions involved between proteins in a chemical complex. Commercial skim milk has been reconstituted and heat treated at 75°C, 85°C and 90°C for 20 minutes. Demineralized whey has been added in concentrations of 0.5%, 1.0 and 2.0%. The soluble protein composition has been determined by the polyacrilamide gel electrophoresis (SDS-PAGE) and by the densitometric analysis. Due to the different changes occurred during treatments at different temperatures, proteins of heat-treated samples containing added demineralized whey have had significantly different solubility. At lower temperatures (75°C and 85°C) the adding of demineralized whey decreased the protein solubility by 5.28%-26.41%, while the addition of demineralized whey performed at 90°C increased the soluble protein content by 5.61%- 28.89%. Heat treatments, as well as the addition of demineralized whey, have induced high molecular weight complex formation. β-Lg, α-La and κ-casein are involved in high molecular weight complexes. The disulfide interactions between denatured molecules of these proteins are mostly responsible for the formation of coaggregates. The level of their interactions and the soluble protein composition are determined by the degree of temperature.
Mededingingsrechtelijke aspecten van import en export (2002)

De importeur of exporteur van producten en diensten krijgt te maken met keuzes die onvermijdelijk worden beinvloed – zo niet afgedwongen – door wettelijke regels. Zo zal men aanlopen tegen regelgeving op het gebied van het te importeren of te exporteren product (denk aan de Nederlandse Warenwet of allerlei technische voorschriften) of zijn verpakking, of eisen die worden gesteld aan een dienstverlener (denk aan beroepsregels). Belemmeringen die door dergelijke regels worden opgeworpen zijn mogelijk in strijd met de bepalingen uit het EG-Verdrag inzake het vrij verkeer van goederen of diensten, dan wel het recht van vestiging. Verder kan men te maken krijgen met belemmeringen die bestaan uit door de overheid gecreeerde monopolies, waardoor de import van een product wordt verhinderd. Een dergelijk monopolie kan onder omstandigheden een mededingingsbelemmering zijn die in strijd is met het EG-Verdrag. Men kan echter niet alleen aanlopen tegen belemmeringen die voortvloeien uit overheidsmaatregelen, maar ook te maken krijgen met de beperkingen en mogelijkheden die het mededingingsrecht aanlegt op het gebied van distributiestelsels. Bij de keuze van het optimale distributiestelsel zal met die beperkingen en mogelijkheden rekening moeten worden gehouden. In deze bijdrage zal worden ingegaan op diverse mededingingsrechtelijke aspecten die relevant zijn voor import en export.
Citric acid as a set retarder for calcium aluminate phosphate cements (2006)

Citric acid added as set retarder significantly contributed to enhancing the setting temperature and to extending the thickening time of a calcium aluminate phosphate (CaP) geothermal cement slurry consisting of calcium aluminate cement (CAC) as the base reactant and sodium polyphosphate (NaP) solution as the acid reactant. The set-retarding activity of citric acid was due to the uptake of Ca 2+ ions from the CAC by carboxylic acid groups within the citric acid. This uptake led to the precipitation of a Ca-complexed carboxylate compound as a setretarding barrier layer on the CAC grains' surfaces. However, this barrier layer was vulnerable to disintegration by the attack of free Ca 2+ ions from CAC, and also to degradation at elevated temperature, thereby promoting the generation of exothermic energy from acid—base reactions between the CAC and NaP after the barrier was broken. The exothermic reaction energy that was promoted in this way minimised the loss in strength of the citric-acid-retarded cement. The phase composition assembled in both retarded and non-retarded cements after autoclaving at 180°C encompassed three reaction products, hydroxyapatite (HOAp), hydrogrossular and boehmite, which are responsible for strengthening the autoclaved cement. The first two reaction products were susceptible to reactions with sulphuric acid and sodium sulphate to form crystalline bassanite scale as the corrosion product. The boehmite phase possessed a great resistance to acid and sulphate. Although the bassanite scales clinging to the surfaces of the cement were the major factor governing the loss in weight, they served to protect the cement from further acid and sulphate corrosion until their spallation eventually occurred. Nevertheless, the repetitive processes of HOAp and hydorgrossular → bassanite → spallation played an important role in extending the useful lifetime of CaP cement in a low pH environment at 180°C.
Low passband sensitivity digital filters: A generalized viewpoint and synthesis procedures (1984)

The concepts of losslessness and maximum available power are basic to the low-sensitivity properties of doubly terminated lossless networks of the continuous-time domain. Based on similar concepts, we develop a new theory for low-sensitivity discrete-time filter structures. The mathematical setup for the development is the bounded-real property of transfer functions and matrices. Starting from this property, we derive procedures for the synthesis of any stable digital filter transfer function by means of a low-sensitivity structure. Most of the structures generated by this approach are interconnections of a basic building block called digital "two-pair," and each two-pair is characterized by a lossless bounded-real (LBR) transfer matrix. The theory and synthesis procedures also cover special cases such as wave digital filters, which are derived from continuous-time networks, and digital lattice structures, which are closely related to unit elements of distributed network theory.

Compact Coradiator UWB-MIMO Antenna With Dual Polarization (2014)

Two compact coradiator multiple-input-multiple-out (MIMO) antennas operating in the UWB frequency band with dual polarization are proposed. Different from traditional MIMO antennas, the radiator is shared by two antenna elements, which greatly reduce the overall size of the MIMO system. High isolation between the two antenna elements is achieved by etching a T-shaped slot in the radiator and extending a stub on the ground. Dual polarization can be realized by exciting the pentagonal radiator with perpendicular feeding structure. The simulated results of current and electric-field distribution show the dual-polarization characteristics of the diversity system. Besides, a four units UWB MIMO antenna is also proposed. Furthermore, the diversity characteristics of mean effective gains (MEGs) and diversity gain (DG) are also studied. The simulated and measured results demonstrate that the UWB-MIMO antenna has good impedance matching, isolation and dual polarization characteristics.
