Active Thermoelectric Vacuum Sensor Based on Frequency Modulation (2019)

This paper introduces a thermoelectric-type sensor with a built-in heater as an alternative approach to the measurement of vacuum pressure based on frequency modulation. The proposed sensor is fabricated using the TSMC (Taiwan Semiconductor Manufacturing Company, Hsinchu, Taiwan) 0.35 μm complementary metal-oxide-semiconductor-microelectro-mechanical systems (CMOS-MEMS) process with thermocouples positioned central-symmetrically. The proposed frequency modulation technique involves locking the sensor output signal at a given frequency using a phase-lock-loop (PLL) amplifier to increase the signal-to-noise ratio (SNR) and thereby enhance the sensitivity of vacuum measurements. An improved first harmonic signal detection based on asymmetrical applied heating gives a precise measurement. Following calibration, the output voltage is in good agreement with the calibration values, resulting in an error of 0.25% under pressures between 0.1-10 Torr.
Sarcoplasmic reticulum in aged skeletal muscle (1999)

This review shows that human jaw muscles not only have unique fibre type and myosin heavy chain (MyHC) compositions but also undergo muscle and region-specific changes in fibre composition during ageing. Alterations in the masseter and the lateral pterygoid muscles in the elderly are opposite to those reported for limb and trunk muscles, whereas changes in the anterior and posterior bellies of the digastric muscle resemble those of limb and trunk muscles. We conclude that age-related alterations in fibre type composition and MyHC expression are muscle and region specific, probably reflecting muscular differences in genetic programs and epigenetic influences.
Acute displacement of the diastolic pressure-volume curve of the left ventricle: role of the pericardium and the right ventricle. (1979)

Lattice models employing trusses and beams are suitable to investigate the mechanical behavior of woven fabrics. The discrete features of the mesostructures of woven fabrics are naturally incorporated by the discrete elements of lattice models. In this paper, a lattice model for woven materials is adopted which consists of a network of trusses in warp and weft direction, which represent the response of the yarns. Additional diagonal trusses are included that provide a resistance against relative rotation of the yarns. The parameters of these families of discrete elements can be separately identified from tensile experiments in three in-plane directions which correspond with the orientations of the discrete elements. The lattice model and the identification approach are applied to electronic textile. This is a fabric in which conductive wires are incorporated to allow the embedment of electronic components such as light-emitting diodes. The model parameters are established based on tensile tests on samples of the electronic textile. A comparison between the experimental results of an out-of-plane punch test and the simulation results shows that the lattice model and its characterization procedure are accurate until extensive biaxial tensile deformation occurs.

Press-fit condylar total knee replacement. (1989)

In 1984 the press-fit condylar knee was first introduced and was intended to provide a condylar knee system primarily for posterior cruciate retention that addressed refinements in metallurgy, prosthetic geometry and sizing, cementless fixation, inventory management, and instrumentation. This article addresses the results observed in the use of this prosthesis.
Chemical composition and antimicrobial activity of the essential oils of different samples of <i>Thymus baeticus</i> boiss (1993)

Abstract Gas chromatography was used to determine the chemical composition of the essential oil of female and hermaphrodite Thymus baeticus Boiss. collected in Ugijar (province of Granada, Spain). The results were compared with the chemical composition of other samples of the same species, collected in Lanjarón. These comparisons showed some qualitative differences, and more obvious quantitative differences, in the compositions of the essential oils. We also investigated the antimicrobial activity of all samples. This activity, although marked in all samples, was greater in essential oils containing larger amounts of geraniol.
Fuzzy inference based non-daily behavior pattern detection for elderly people monitoring system (2009)

This paper describes an abnormal behavior detection system based on an omni-directional vision sensor as one of the important elements in realizing "Sensing and Robotic Support Room" for elderly people. Such support rooms are expected to be further developed in the future with the high performance to automatically recognize elderly people's actions and behavior patterns and detect the unusual patterns using some sensors and to support their daily motions using some robotic manipulator control systems. The proposed monitoring system using an omni-directional vision sensor automatically learns the daily behavior patterns and detects the unusual behavior patterns and actions using fuzzy inference approach. The fuzzy rules are constructed using image feature values such as the area and center-of gravity values extracted from the captured image sequence and their patterns appearance frequency. Unusual behavior patterns can be automatically detected based on the possibility distribution inference method. Some experiments based on the investigation of elderly people's typical daily behavior patterns show the effectiveness of the proposed system.
Structure of the Covering Layers of the Wild Oat (<i>Avena fatua</i>) Caryopsis (1982)

The anatomy of the husk (lemma and palea) and caryopsis coat (pericarp, seed coat or testa, and nucellar epidermis) of a typical mature wild oat ( Avena fatua L.) caryopsis was investigated using both scanning electron microscopy and light microscopy. Both the lemma and palea consist of very thick-walled, lignified cells. In section, the lemma appears almost twice as thick as the palea. The pericarp is comprised of only one or two layers of relatively thin-walled cells and is closely appressed to the underlying seed coat over most of the grain. Both the outer seed-coat cuticle and the inner cuticle are present over almost the entire caryopsis and are continuous with the pigment strand that occurs deep in the crease region of the grain. The only discontinuities in the seed coat are at the basal end of the grain near the embryo. In the dorsal region of the caryopsis, the outer cuticle is approximately 3.5 μm in thickness, whereas the inner cuticle is less than 1 μm in thickness. Where the two pass over the embryo they are much thinner, with the inner cuticle becoming almost indistinguishable in places. The remains of the nucellar epidermis are tightly amalgamated to the seed coat and outer tangential walls of the underlying aleurone cells, which are clearly distinguishable by their large size and characteristic appearance.

Synthesis of Functional Polypropylene Containing Hindered Phenol Stabilizers and Applications in Metallized Polymer Film Capacitors (2015)

This paper discusses a new family of polymeric stabilizers (antioxidants) containing a polypropylene backbone and several pendant hindered phenol groups (PP-HP), with both random and tapered copolymer microstructures. They are effectively prepared by Steglich esterification of the corresponding hydroxylated polypropylene (PP-OH) copolymers with the hindered phenol molecule containing a carboxylic acid moiety. Some resulting PP-HP copolymers show significantly higher thermal-oxidative stability than the pristine PP polymer and the commercial PP products that contain a small amount of organic hindered phenol stabilizers. The better oxidative stability was also observed in PP/PP-HP blends under elevated temperatures. Overall, the PP chain degradation temperature increases with the increase of HP concentration in the matrix. The effectiveness of the PP-HP stabilizer is attributed to its comparability and cocrystallization with the PP homopolymer, which result in a uniform distribution of hindered phenol moieties. It also allows the relatively higher concentration of hindered phenol (polar) moieties in the PP (nonpolar) matrix without phase separation. In addition to the known advantages of polymer-bonded stabilizers, with low mobility and volatility to prevent loss through diffusion and/or extraction (particularly acute in films and coatings), the PP-HP thin dielectric films with uniform morphology show a higher dielectric constant and maintain low dielectric loss, particularly for the tapered PP-HP copolymers with high crystallinity.

LOSSES IN RUBY LASERS. THE SPHERICAL-MIRROR FABRY-PEROT INTERFEROMETER. (1967)

A comprehensive study of the losses in ruby lasers is described. The passive losses (umpumped crystal) were studied with a 6328A laser probe and a scanning interferometer. In the optically pumped crystal, the excited-state population was inferred from excited-state absorption at 6328A, and then used to accurately determine active laser losses. For high quality ruby crystals, losses were on the order of 0.03/cm in the passive state, increasing to approximately twice this value when optically pumped. Observed losses at 6328A were in good agreement with calculations based on Mie scattering cross-sections. The excited-state absorption coefficient from the 2E level in ruby at 6943A was found to be 0.0 plus or minus 0.05/cm. Losses due to thermal distortion of the ruby rod were found to be negligible during pulsed operation of the laser. An appendix to this report gives a detailed description of the spherical-mirror Fabry-Perot interferometer, and specific interferometer designs are discussed. (Author)
Concordance of primary generalised epilepsy and carbamazepine hypersensitivity in monozygotic twins (1999)

In this paper we describe the previously unreported phenomenon of a carbamazepine-induced mucocutaneous syndrome in identical twins. These twins had developed primary generalised epilepsy within 2 months of each other.
Cutting balloon angioplasty through stent struts of a jailed sidebranch ostial lesion. (2002)

The treatment of sidebranch ostial lesions jailed after stent implantation is challenging. We report a case of successful Cutting Balloon angioplasty through stent struts of a severe, elastic sidebranch ostial lesion. Three-day follow-up angiography showed no recurrent stenosis. The patient was discharged with complete resolution of chest discomfort and the post-hospitalization course was uneventful. Cutting Balloon angioplasty may be an optimal strategy for the treatment of elastic ostial lesions in smaller vessels that are suboptimal for stenting. The long-term benefits of using a Cutting Balloon for the treatment of sidebranch ostial lesions are still to be determined.
An Audio Watermark Designed for Efficient and Robust Resynchronization After Analog Playback (2017)

We propose a spread spectrum (SS) audio watermark designed to withstand analog playback, including desynchronization caused by small differences between playback and recording rates. Desynchronization robustness relies on detecting short blocks of a magnitude-only watermark embedded in the frequency domain where the resolution of the SS chips can be reduced. Lost spreading gain due to the lower number of SS chips is compensated using blind dynamic time warping (DTW) detection (does not access original signal). DTW aligns sequences of blocks to improve robustness to interference while mitigating the vulnerabilities of long SS sequences to desynchronization. Results demonstrate that the proposed watermark survives analog playback and warping up to ±2%. Additionally, compared with a recent baseline scheme that uses brute force resampling to search for resynchronization, the proposed watermark is 300 times more computationally efficient, and does not compromise robustness to either desynchronization (e.g., jitter, resampling, time warping, frequency scaling) or non-desynchronizing modifications (e.g., AAC compression and additive noise).
<title>Designing a VMEbus FDDI adapter card</title> (1992)

This paper presents a system architecture for a VMEbus FDDI adapter card containing a node core, FDDI block, frame buffer memory and system interface unit. Most of the functions of the PHY and MAC layers of FDDI are implemented with National's FDDI chip set and the SMT implementation is simplified with a low cost microcontroller. The factors that influence the system bus bandwidth utilization and FDDI bandwidth utilization are the data path and frame buffer memory architecture. The VRAM based frame buffer memory has two sections - - LLC frame memory and SMT frame memory. Each section with an independent serial access memory (SAM) port provides an independent access after the initial data transfer cycle on the main port and hence, the throughput is maximized on each port of the memory. The SAM port simplifies the system bus master DMA design and the VMEbus interface can be designed with low-cost off-the-shelf interface chips.
Information-centric network function virtualization over 5g mobile wireless networks (2015)

Wireless network virtualization and information-centric networking (ICN) are two promising techniques in software-defined 5G mobile wireless networks. Traditionally, these two technologies have been addressed separately. In this paper we show that integrating wireless network virtualization with ICN techniques can significantly improve the end-to-end network performance. In particular, we propose an information- centric wireless network virtualization architecture for integrating wireless network virtualization with ICN. We develop the key components of this architecture: radio spectrum resource, wireless network infrastructure, virtual resources (including content-level slicing, network-level slicing, and flow-level slicing), and informationcentric wireless virtualization controller. Then we formulate the virtual resource allocation and in-network caching strategy as an optimization problem, considering the gain of not only virtualization but also in-network caching in our proposed information-centric wireless network virtualization architecture. The obtained simulation results show that our proposed information-centric wireless network virtualization architecture and the related schemes significantly outperform the other existing schemes.
Institutional Digital Repositories in Nigerian: Issues and Challenges (2014)

This paper explores the historical development, current practices and the challenges affecting the institutional digital repositories in Nigeria; it identifies the various universities that establish digital repositories. The paper further highlight the prospect of Nigerian University Libraries in the implementing institutional digital repositories as it holds great promise for preservation of materials, sharing of resources, and visibility of Nigerian libraries and institutions across the globe. The increase in Nigerian content on the Web will enable more meaningful and fruitful researches to be conducted through access to relevant data and literature. The study discovers finance, copyright issues, epileptic power supply, difficulty in digitizing some materials, technical support and security; constant change of hardware and software are among the challenges facing the digitization project and institutional repositories respectively. The research concludes that digitization of library resources in the 21st Century can revitalized the libraries as information provider. 1991 the e-print service arXiv was developed by Los Alamos physicist Paul Ginsparg. It eventually led to the Open Archive Initiative in which it enables institutional repositories to operate together. In 2001 Eprints was developed, while 2002 Dspace and HP and in that same year FEDORA (Flexible Extensible Digital Object Repository Architecture) was developed. This software is used as platform to deploy IRs. They are the programmes that provide structured data-entry points for digital resources leading to semantic relationships. Semantic relationships are further enhanced by the introduction of metadata, i.e. data about data, which increases the direct findability of resources, rather than mere accessibility. Find ability of resources is used to denote the aggregation of relevant materials in their order of importance, with synonyms, and with options for different media or format, such as texts, sound, motion, graphics, or any combinations of these
Substantial Health And Economic Returns From Delayed Aging May Warrant A New Focus For Medical Research (2013)

Recent scientific advances suggest that slowing the aging process (senescence) is now a realistic goal. Yet most medical research remains focused on combating individual diseases. Using the Future Elderly Model--a microsimulation of the future health and spending of older Americans--we compared optimistic "disease specific" scenarios with a hypothetical "delayed aging" scenario in terms of the scenarios' impact on longevity, disability, and major entitlement program costs. Delayed aging could increase life expectancy by an additional 2.2 years, most of which would be spent in good health. The economic value of delayed aging is estimated to be $7.1 trillion over fifty years. In contrast, addressing heart disease and cancer separately would yield diminishing improvements in health and longevity by 2060--mainly due to competing risks. Delayed aging would greatly increase entitlement outlays, especially for Social Security. However, these changes could be offset by increasing the Medicare eligibility age and the normal retirement age for Social Security. Overall, greater investment in research to delay aging appears to be a highly efficient way to forestall disease, extend healthy life, and improve public health.

Terbinafine in Combination with Other Antifungal Agents for Treatment of Resistant or Refractory Mycoses: Investigating Optimal Dosing Regimens Using a Physiologically Based Pharmacokinetic Model (2013)

ABSTRACT Terbinafine is increasingly used in combination with other antifungal agents to treat resistant or refractory mycoses due to synergistic in vitro antifungal activity; high doses are commonly used, but limited data are available on systemic exposure, and no assessment of pharmacodynamic target attainment has been made. Using a physiologically based pharmacokinetic (PBPK) model for terbinafine, this study aimed to predict total and unbound terbinafine concentrations in plasma with a range of high-dose regimens and also calculate predicted pharmacodynamic parameters for terbinafine. Predicted terbinafine concentrations accumulated significantly during the first 28 days of treatment; the area under the concentration-time curve (AUC)/MIC ratios and AUC for the free, unbound fraction ( f AUC)/MIC ratios increased by 54 to 62% on day 7 of treatment and by 80 to 92% on day 28 compared to day 1, depending on the dose regimen. Of the high-dose regimens investigated, 500 mg of terbinafine taken every 12 h provided the highest systemic exposure; on day 7 of treatment, the predicted AUC, maximum concentration ( C max ), and minimum concentration ( C min ) were approximately 4-fold, 1.9-fold, and 4.4-fold higher than with a standard-dose regimen of 250 mg once daily. Close agreement was seen between the concentrations predicted by the PBPK model and the observed concentrations, indicating good predictive performance. This study provides the first report of predicted terbinafine exposure in plasma with a range of high-dose regimens.

Incentives in Teams (1973)

This paper analyzes the problem of inducing the members of an organization to behave as if they formed a team. Considered is a conglomerate-type organization consisting of a set of semi-autonomous subunits that are coordinated by the organization's head. The head's incentive problem is to choose a set of employee compensation rules that will induce his subunit managers to communicate accurate information and take optimal decisions. The main result exhibits a particular set of compensation rules, an optimal incentive structure, that leads to team behavior. Particular attention is directed to the informational aspects of the problem. An extended example of a resource allocation model is discussed and the optimal incentive structure is interpreted in terms of prices charged by the head for resources allocated to the subunits.
Effects of Phosphatidylserine on the Neuroendocrine Response to Physical Stress in Humans (1990)

The activity of brain cortex-derived phosphatidylserine (BC-PS) on the neuroendocrine and neurovegetative responses to physical stress was tested in 8 healthy men who underwent three experiments with a bicycle ergometer. According to a double-blind design, before starting the exercise, each subject received intravenously, within 10 min, 50 or 75 mg of BC-PS or a volume-matched placebo diluted in 100 ml of saline. Blood samples were collected before and after the exercise for plasma epinephrine (E), norepinephrine (NE), dopamine (DA), adrenocorticotropin (ACTH), cortisol, growth hormone (GH), prolactin (PRL) and glucose determinations. Blood pressure and heart rate were also recorded. Physical stress induced a clear-cut increase in plasma E, NE, ACTH, cortisol, GH and PRL, whereas no significant change was observed in plasma DA and glucose. Pretreatment with both 50 and 75 mg BC-PS significantly blunted the ACTH and cortisol responses to physical stress.
