Analysis of a Porous Elastic Sheet Damper With a Magnetic Fluid (2009)

In progress of anti-shock characteristics of small size precision equipment, a miniaturized damper is required to have better damping characteristics. However, damping efficiency becomes less as damper size decreases, and so for compensation of its defect, a porous elastic sheet damper with a magnetic fluid is proposed. An analytical estimation of this sheet damper is presented to investigate variation of damping characteristics with intensity and direction of a magnetic field and to give effects of porosity of porous sheets on damping characteristics.
On board flight computers for flight testing small uninhabited aerial vehicles (2003)

This paper will discuss two systems that were developed to support UAV flight test efforts. The Flight Computer System (FCS) was based on the DS2250 embedded controller, an 8051 derivative. The FCS is small and lightweight, but it has limited I/O and computational capabilities, which were expanded by using a FCS network. The analog to digital converters on the FCS were a novel design, which would also generate a hybrid integration of the signal. The Linux In Flight Testing (LIFT) system is based on the use of COTS PC104-Plus cards using a Real-Time Linux operating system. The RT Linux provides the hard real-time capability required for quality data collection and control system implementation. The LIFT system provides for expansion to satisfy complex mission requirements.
The induction of enzyme activity in the endosperm of germinating castor-bean seeds (1975)

Endosperm extracts were prepared at various times during germination from intact castor-bean seeds and from seeds from which the embryos had been removed. The sterilized seeds were incubated either on solid water agar or on agar containing 0.3 mM-gibberellic acid. 2. Isocitrate lyase and 3-hydroxyacyl-CoA dehydrogenase had very low activities in the mature seeds, but increased 44-fold and 27-fold respectively during germination. In contrast, the extracts of mature seeds had considerable acid and alkaline lipase activity and this only increased two- to three-fold during the incubation period. 3. Incubation of the seeds with gibberellic acid accelerated the rate of appearance of isocitrate lyase and 3-hydroxyacyl-CoA dehydrogenase. It also increased the total activity attained. However, the application of hormone had, in comparison, little effect on the development of lipase activity. 4. The removal of the embryo had little influence on the development of enzyme activity in the endosperm tissue; only with isocitrate lyase was a decrease in activity observed in the absence of the embryo.
Lifetime risk of dementia and Alzheimer's disease (1997)

We estimated the remaining lifetime risks of developing Alzheimer's disease (AD) and dementia from all causes, based on data from longitudinal population studies. The risk of developing AD during one's lifetime depends on both disease incidence and life expectancy. Conventional estimates of cumulative incidence overestimate the risk when there is a substantial probability of mortality due to competing causes. A total of 2,611 cognitively intact subjects (1,061 men, 1,550 women; mean age, 66 +/- 7 years) were prospectively evaluated for the development of AD or other dementia. A modified survival analysis was used to estimate both cumulative incidence and the sex-specific remaining lifetime risk estimates for quinquennial age groups above age 65 years. Over a 20-year follow-up period, 198 subjects developed dementia (120 with AD). The remaining lifetime risk of AD or other dementia depended on sex, being higher in women, but varied little with age between 65 and 80 years. In a 65-year-old man, the remaining lifetime risk of AD was 6.3% (95% CI, 3.9 to 8.7) and the remaining lifetime risk of developing any dementing illness was 10.9% (95% CI, 8.0 to 13.8); corresponding risks for a 65-year-old woman were 12% (95% CI, 9.2 to 14.8) and 19% (95% CI, 17.2 to 22.5). The cumulative incidence between age 65 and 100 years was much higher: for AD, 25.5% in men and 28.1% in women; for dementia, 32.8% in men and 45% in women. The actual remaining lifetime risk of AD or dementia varies with age, sex, and life expectancy and is lower than the hypothetical risk estimated by a cumulative incidence in the same population.
Summary of 1974 IEEE annual conference on nuclear and space radiation effects (1974)

The eleventh IEEE Annual Conference on Nuclear and Space Radiation Effects was held in Fort Collins, Colorado on July 15–18, 1974 on the campus of Colorado State University. More than 290 attended. The Conference was officially sponsored by the Radiation Effects Committee of the IEEE Nuclear and Plasma Sciences Society in cooperation with the Office of Conferences and Institutes, Colorado State University and partially supported by the Defense Nuclear Agency.
A New SOA Data-Provenance Framework (2007)

Due to the dynamic nature, such as runtime composition and evaluation, it is critical for an SOA system to consider its data provenance, which concerns security, reliability, and integrity of data as it is routed in the system. In a traditional software system, one can focus on the software itself to determine the security, reliability, and integrity; however, in an SOA system, one also needs to consider the origins and routes of data and their impact, i.e., data provenance. This paper first analyzes the unique natures and characteristics of data provenance in an SOA system. Then it proposes a new framework to classify data provenance and collect data in SOA systems. Finally, this paper uses an example to illustrate these concepts and techniques
Partial Dissociation of Water Leads to Stable Superstructures on the Surface of Zinc Oxide (2004)

Half-dissociated: Experimental and computational findings conclude that water forms a highly ordered superstructure on defect-free surfaces of zinc oxide, in which every second water molecule is dissociated (see picture). The results are of general relevance for heterogeneous catalysis.
Conceptions of schizophrenia (2006)

Abstract What I have done is given an overview of the issues raised and discussed thus far by philosophers, psychiatrists, and psychologists, on the subject of schizophrenia. The breadth of the issues investigated reflect a significant step toward understanding or reconceiving schizophrenia. It also reflects the perplexity and complexity of schizophrenia that professionals and academics are facing. In my view, the investigation of these issues has shed new light on the theoretical thinking, which underpins clinical practice and philosophical pursuit. It has also set the stage for further debate and research in the area of schizophrenia.

Cell wall mechanics and growth control in plants: the role of pectins revisited (2012)

How is the extensibility of growing plant cell walls regulated? In the past, most studies have focused on the role of the cellulose/xyloglucan network and the enigmatic wall-loosening agents expansins. Here we review first how in the closest relatives of the land plants, the Charophycean algae, cell wall synthesis is coupled to cell wall extensibility by a chemical Ca(2+)-exchange mechanism between Ca(2+)-pectate complexes. We next discuss evidence for the existence in terrestrial plants of a similar "primitive" Ca(2+)-pectate-based growth control mechanism in parallel to the more recent, land plant-specific, expansin-dependent process.
"Wildly Enthusiastic" About the First Multilateral Agreement on Trade in Telecommunications Services (1998)

In 1998, the World Trade Organization’s (WTO) "Basic Telecom Agreement" dramatically opened to foreign competition basic telecommunications services of the sixty-nine WTO Members committing to the Agreement. The process and results of the WTO negotiations are important to telecommunications consumers because there will be increased market competition, thereby decreasing the price of such services and increasing consumer choice. The negotiations that led to the WTO Agreement resolved many difficult issues including: scheduling, regulator’s independence, competitive safeguards, and interconnection of telecommunications suppliers. The resolution of these issues will allow market access and foreign ownership in over 90 percent of major markets. These negotiations were only the beginning of the process and implementation of the Agreement will provide new challenges.
Experimental Verification of Electroosmotic Dehumidification with Nafion and Plaster-Silica Gel Membranes (2008)

In electroosmotic dehumidification, a membrane composed of a desiccant material removes moisture from air to be conditioned.Then, electroosmotic pumping driven by the application of voltage moves the moisture across the membrane and rejects it on the other side.A bench top experiment was developed to screen promising membrane materials.Two sealed humidity chambers were separated by a membrane.The changes in the humidity of the chambers were measured as current was applied to the membrane.The most successful inorganic membrane tested was a silica gel concrete using Plaster of Paris as the cement and silica gel particles as the aggregate.Nafion membranes were also tested and showed a higher current, mass flow rate, and water vapor partial pressure differential.However, the electroosmotic flux is significantly smaller than predicted.Further research is needed to reconcile the experimental data and modeling in order to determine feasibility.
Nanoparticle routes to mesoporous titania thin films (2001)

Controlled aging of TiO2 nanoparticles blended with diblock copolymers and processed into dip-coated thin films led to ordered mesostructures with cubic and hexagonal symmetries that can be transformed into mesoporous TiO2 by calcination.
Giant magnetic coercivity and percolation effects in granular Fe-(SiO2) solids (1987)

We demonstrate a novel method for enhancing the coercivity of magnetic materials. Granular Fe-(SiO2) solids have been fabricated over a wide volume fraction range from 15% to 100%. Giant magnetic coercivity, as high as 2500 Oe, has been observed in granular solids in which the isolated Fe granules are only nanometers in size. Across the whole volume fraction range magnetic coercivity experiences dramatic variations due to the change of granular size and percolation effects.
Engineering Artificial Small RNAs for Conditional Gene Silencing in <i>Escherichia coli</i> (2011)

It has become increasingly evident that noncoding small RNAs (sRNAs) play a significant and global role in bacterial gene regulation. A majority of the trans-acting sRNAs in bacteria interact with the 5' untranslated region (UTR) and/or the translation initiation region of the targeted mRNAs via imperfect base pairing, resulting in reduced translation efficiency and/or mRNA stability. Additionally, bacterial sRNAs often contain distinct scaffolds that recruit RNA chaperones such as Hfq to facilitate gene regulation. In this study, we describe a strategy to engineer artificial sRNAs that can regulate desired endogenous genes in Escherichia coli. Using a fluorescent reporter gene that was translationally fused to a native 5' mRNA leader sequence, active artificial sRNAs were screened from libraries in which natural sRNA scaffolds were fused to a randomized antisense domain. Artificial sRNAs that posttranscriptionally repress two endogenous genes ompF and fliC were isolated and characterized. We anticipate that the artificial sRNAs will be useful for dynamic control and fine-tuning of endogenous gene expression in bacteria for applications in synthetic biology.
조대분말과 미세분말을 혼합한 철분말의 사출성형 (1992)

To investigate the applicability of a coarse powder to the metal injection molding, coarse iron podwers were combined up to 60% in weight fraction with fine iron powders in the injection molding process. With increasing relative fraction of a coarse powder, the green density of the compacts increased slowly up to 97% at 60 wt. % addition of coarse powder and it became possible to remove a binder completely out of the compact through the broader channels of binder flow during the debinding stage. The increase in the porosity of the compact owing to the increasing portion of a coarse powder resulted in the decrease in the sintered density and volume shrinkage. And then it brought the tensile strength and elongation of the final product down. In this experiment the maximum amount of a coarse powder replacing a fine powder with the equivalence in densification behavior, microstructure and tensile property to injection molded-fine carbonyl iron powder was found to be 20% in weight fraction.
[Netherton syndrome]. (1981)

The case of a 8 years old girl, who since the delivery had suffered from a generalized, erythematous and scaling eruption of the skin is reported. She also had a sparse, short and brittle hair. Abnormalities such as trichorrhexis nodosa and pilo torti were observed. The finding of a generalized increase of the urinary aminoacids, excretion especially for Glycine and Serine, is added to this features.
A macromodelling methodology for efficient high-level simulation of substrate noise generation (2004)

Efficient prediction of the substrate noise generated by digital sections is currently a major challenge in system-on-a-chip design. In this paper a macromodel to accurately and efficiently predict the substrate noise generated by digital standard cells is presented. The macromodel accuracy is demonstrated for some simple circuits.
Nonstoichiometry in inorganic fluorides: 2. Ionic conductivity of nonstoichiometric M 1 − x R x F2 + x and R 1 − y M y F3 − y crystals (M = Ca, Sr, Ba; R are rare earth elements) (2014)

The peak manifestation of nonstoichiometry in fluoride systems in the number of phases with valuable properties and wide homogeneity ranges is 45 MF2-RF3 systems, where M = Ca, Sr, Ba and R are 15 rare earth elements from La to Lu and Y (with Pm and Sc excluded). A deviation from stoichiometry in crystals of the M 1 − x R x F2 + x (CaF2 fluorite type) and R 1 − y M y F3 − y (LaF3 tysonite type) phases is responsible for the fluorine superionic conductivity σ. The range of variation in σ with changes in the qualitative (M, R) and quantitative (x, y) compositions in both structure types is very wide. The σ value changes by a factor of 108 in the M 1 − x R x F2 + x phases (at 500 K) and by a factor of 106 in the R 1 − y M y F3 − y phases (at 293 K). Changing compositions, one can also obtain crystals with σ values large enough for their use as fluorine-conducting solid electrolytes. Phases promising for solid electrolytes were revealed in the MF m -RF n systems (m < n ≤ 4), which were studied within the program of searching for new multicomponent fluoride materials at the Institute of Crystallography, Russian Academy of Sciences (IC RAS). Superionic conductivity is one of the peak manifestations of the influence of defect structure of nonstoichiometric crystals on their properties. The subject of this review is the results of the studies performed at the IC RAS on the ionic conductivity of single crystals of the M 1 − x R x F2 + x and R 1 − y M y F3 − y nonstoichiometric phases.
A Yellow Zosterops Sighting at Sawtell (2009)

The article discusses the yellow Zosterops bird, which the author photographed at Sawtell in New South Wales. The bird, after several consultations with experts, was found to be a vagrant, possibly immature Z. luteus.
A High Speed Cu Pillar Bump Plating Process (2008)

Cu pillars have been adopted and implemented in high volume manufacturing environment as early as 2006 as a replacement for high lead bumps. It is not only lead-free, but also offers the added advantage of higher stand-off, finer pitch capability and better electromigration resistance compared to tin-lead solder bumps. Cu pillar technology promises to be one of the main interconnect technologies in advanced packaging arena together with other lead-free solder processes and Cu plated through silicone vias (TSV) in the years to come. Within wafer (WIW), within die (WID) and within feature (WIF) uniformity become increasingly important as pillar diameter, pitch size shrinks and photoresist thickness increases. There is a trade off when it comes to plating speed and uniformity. Generally speaking, when plating speed increases beyond 2 mum/min, the uniformity suffers. That is why most of the conventional plating processes are operated at 2 mum/min or below. Under certain conditions, few processes could be "stretched" to up to 3 mum/min but process window becomes rather narrow and the plating process and quality becomes difficult to control. When the photoresist (or pillar) height approaches 120 mum, it is desirable to employ a plating process that is capable of 4 mum/min or higher to increase throughput while meeting uniformity and surface roughness requirements, and producing Cu pillars with materials properties similar or superior to those obtained with conventional Cu plating processes. In this paper, we describe a high speed Cu pillar plating process that fits above description.
How tumor stage affects surgeons' surveillance strategies after colon cancer surgery (1995)

Surgeons performing surveillance after potentially curative surgery for otherwise healthy patients with colon cancer modify their strategies according to the patient's TNM Stage. These data should help in the design of prospective trials related to this topic.
Gamma-H2AX biodosimetry for use in large scale radiation incidents: comparison of a rapid ‘96 well lyse/fix’ protocol with a routine method (2014)

Following a radiation incident, preliminary dose estimates made by γ-H2AX foci analysis can supplement the early triage of casualties based on clinical symptoms. Sample processing time is important when many individuals need to be rapidly assessed. A protocol was therefore developed for high sample throughput that requires less than 0.1 ml blood, thus potentially enabling finger prick sampling. The technique combines red blood cell lysis and leukocyte fixation in one step on a 96 well plate, in contrast to the routine protocol, where lymphocytes in larger blood volumes are typically separated by Ficoll density gradient centrifugation with subsequent washing and fixation steps. The rapid '96 well lyse/fix' method reduced the estimated sample processing time for 96 samples to about 4 h compared to 15 h using the routine protocol. However, scoring 20 cells in 96 samples prepared by the rapid protocol took longer than for the routine method (3.1 versus 1.5 h at zero dose; 7.0 versus 6.1 h for irradiated samples). Similar foci yields were scored for both protocols and consistent dose estimates were obtained for samples exposed to 0, 0.2, 0.6, 1.1, 1.2, 2.1 and 4.3 Gy of 250 kVp X-rays at 0.5 Gy/min and incubated for 2 h. Linear regression coefficients were 0.87 ± 0.06 (R (2) = 97.6%) and 0.85 ± 0.05 (R (2) = 98.3%) for estimated versus actual doses for the routine and lyse/fix method, respectively. The lyse/fix protocol can therefore facilitate high throughput processing for γ-H2AX biodosimetry for use in large scale radiation incidents, at the cost of somewhat longer foci scoring times.
Implementation of TCP large receive offload on multi-core NPU platform (2016)

Nowadays, the ethernet is developing much faster than memory and CPU technologies, protocol processing has become the bottleneck of TCP performance on end systems. Modern NICs usually support offload techniques such as checksum offload and TCP Segmentation Offload(TSO), allowing the end system to offload some processing work onto the NIC hardware. In this paper, we propose an implementation of Large Receive Offload(LRO) on a multi-core NPU platform to improve TCP performance, particularly, we employ a so called active ACK mechanism to make very large packets(64KB) aggregation possible. We present experiment results to demonstrate the effectiveness of our proposal.
Effects of some capsular components on pathogenicity of type IV and provisional type V group B streptococci (1987)

Recently, 2 new Group B Streptococcus (GBS) serotypes, IV and provisional V, have been described. To gain information on the relationship between pathogenicity and occurrence of some specific bacterial components, we studied the virulence in a mouse model, the ultrastructural aspect of type IV and V cells, and their sialic acid content. The new serotypes exhibited very low virulence for the mouse, similar to that found in GBS serotype III. The amount of sialic acid present on the bacterial surface (4.8 mg/g of bacterial cells in type IV and 1.8 mg/g in provisional type V) accorded well with this low virulence. When pretreated with type-specific antisera, a very thin and irregular layer of capsular material surrounded the cells in type IV, while a clearly defined capsule was observed in provisional type V.
A full model calibration algorithm for a dual six-port network analyzer (2002)

A novel dual six-port network analyzer calibration procedure is presented. The calibration algorithm is based on a full model. Calibration measurements with TMSO and three other unknown standards are sufficient to calculate the error coefficients of the analyzer. Besides this, a simple and unique determination of error corrected scattering parameters of any device under test (DUT) is presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Molecular Analysis of a Recurrent Sarcoma Identifies a Mutation in FAF1 (2015)

A patient presented with a recurrent sarcoma (diagnosed as leiomyosarcoma) 12 years after the removal of an initial cancer (diagnosed as extracompartmental osteosarcoma) distally on the same limb. Following surgery, the sarcoma and unaffected muscle and bone were subjected to measurements of DNA exome sequence, RNA and protein expression, and transcription factor binding. The investigation provided corroboration of the diagnosis leiomyosarcoma, as the major upregulations in this tumor comprise muscle-specific gene products and calcium-regulating molecules (calcium is an important second messenger in smooth muscle cells). A likely culprit for the disease is the point mutation S181G in FAF1, which may cause a loss of apoptotic function consecutive to transforming DNA damage. The RNA levels of genes for drug transport and metabolism were extensively skewed in the tumor tissue as compared to muscle and bone. The results suggest that the tumor represents a recurrence of a dormant metastasis from an originally misdiagnosed neoplasm. A loss of FAF1 function could cause constitutive WNT pathway activity (consistent with the downstream inductions of IGF2BP1 and E2F1 in this cancer). While the study has informed on drug transport and drug metabolism pharmacogenetics, it has fallen short of identifying a suitable target for molecular therapy.
A CMOS buffer without short-circuit power consumption (2000)

A new CMOS buffer without short-circuit power consumption is proposed. The gate-driving signal of the output pull-up (pull-down) transistor is fed back to the output pull-down (pull-up) transistor to get tri-state output momentarily, eliminating the short-circuit power consumption, The HSPICE simulation results verified the operation of the proposed buffer and showed the power-delay product is about 15% smaller than conventional tapered CMOS buffer.
