Cardiac surgery risk-stratification models (2012)

Risk models are widely used to predict outcomes after cardiac surgery. Not only is risk modelling applied in the assessment of the relative impact of specific risk factors on surgical outcomes, but also in patient counselling, the selection of treatment options, comparison of postoperative results, and quality-improvement programmes. At least 19 risk-stratification models exist for open-heart surgery. The focus of risk models was originally on pre-operative prediction of mortality. However, major morbidity is in general more common than mortality and the ability to predict only operative mortality is not an adequate method of determining surgical outcome. Multiple intra- and postoperative variables have been excluded in the majority of models and the possible effect of their future inclusion remains to be seen. The unique patient population of sub-Saharan Africa requires a unique risk model that reflects the patient population and levels of care.
Mobility Data Warehousing and Mining (2009)

The usage of location aware devices, such as mobile phones and GPS-enabled devices, is widely spread nowadays, allowing access to large spatiotemporal datasets. The space-time nature of this kind of data results in the generation of huge amounts of mobility data and imposes new challenges regarding the analytical tools that can be used for transforming raw data to knowledge. In our research, we investigate the extension of Data Warehousing and data mining technology so as to be applicable on mobility data. In this paper, we present the, so far, developed framework for analyzing mobility data and some preliminary results. 1.
Effect of calcium antagonists on allergen‐induced asthma (1982)

The protective effect of inhaled verapamil (estimated dose 2 . 4 mg) and sub-lingual nifedipine (20 mg) against allergen-induced asthma were each assessed by the administration of calcium antagonists 30 min before bronchial provocation tests using Dermatophagoides pteronyssinus extracts on eight young perennial asthmatics. Neither drug changed the basal forced expiratory volume in one second (FEV1) or the provocation dose of allergen required to cause a 20% fall in FEV1 (PD20 . FEV1). That calcium antagonists are ineffective in preventing allergen-induced asthma suggest indirectly that mechanism other than mediator release from mast cells may also be involved.
Reactions of N-arylsulfonylquinone imines with enamines (2011)

Depending on the reaction conditions N-arylsulfonyl-1,4-quinone imines with enamines led to the formation of the products of 1,4-addition, derivatives of benzo- and naphthofuran, indole, and benzindole.
Licence to govern (1991)

In this chapter I consider word-internal empty nuclei preceded by a consonant cluster. I provide a principled account for the fact that in this context a properly governable empty nucleus fails to be properly governed and receives a phonetic interpretation. To do so I introduce a new notion: government-licensing. I argue that a non-nuclear head can govern a complement only if (i) it has the required charm value or, if charmless, the required complexity, and (ii) it is government-licensed by the nucleus governing it. Government-licensing accounts for, among other things, the phonetic realization of an empty nucleus following a governing onset (i.e. a non-nuclear skeletal point which governs a complement), or for the simplification of a consonant cluster preceding an unrealized empty nucleus. If, in order to govern a complement, a non-nuclear point must be government-licensed and if a properly governed empty nucleus may not be such a licenser, in a situation where a properly governable empty nucleus follows a consonant cluster, the two following possibilities are predicted: (i) in order to government-license the consonant, the empty nucleus will fail to be properly governed, or (ii) proper government will apply, thus preventing the non-nuclear head from governing its complement, which entails the loss of this complement or of this non-nuclear head.
GYRATORY TESTING MACHINE PROCEDURES FOR SELECTING THE DESIGN ASPHALT CONTENT OF PAVING MIXTURES (1964)

PAVING MIXES OF CRUSHED ROCK, NATURAL GRAVEL, SAND, LIMESTONE FILLER AND PAVING GRADE ASPHALTS WERE TESTED IN THE GYRATORY COMPACTION MACHINE. WHEN MIXES CONTAINING VARYING ASPHALT CONTENTS WERE COMPACTED WITH A CONSTANT GYRATORY EFFORT, THE ANGLES OF GYRATION RECORDED DURING THE LAST FEW REVOLUTIONS ARE CONSTANT UNTIL A CRITICAL ASPHALT CONTENT IS REACHED, AT, OR ABOVE WHICH ANGLES OF GYRATION INCREASE RAPIDLY. STUDIES INDICATE THE VOIDS IN MINERAL AGGREGATE WERE ESSENTIALLY FILLED WITH ASPHALT AT THE CRITICAL ASPHALT CONTENTS WITH THE AIR VOIDS CONSISTENTLY ONE PER CENT OR LESS. ACCORDING TO ACCEPTED CRITERIA, ACCEPTABLE AIR VOIDS ARE OBTAINED AT ONE PER CENT LESS ASPHALT THAN PER CENT AT THE CRITICAL POINT. DESIGN ASPHALT CONTENTS BY THE GYRATORY METHOD USING 100 PSI, ONE DEGREE ANGLE OF GYRATION, AND 30 REVOLUTIONS AGREE VERY CLOSELY WITH 50 BLOW MARSHALL DESIGN CONTENTS. THE 75 BLOW MARSHALL AND HVEEM DESIGN ASPHALT CONTENTS WERE ESSENTIALLY THE SAME AS THAT BY THE GYRATORY METHOD AT 200 PSI PRESSURE. OTHER VARIABLES SUCH AS TEMPERATURE, SPECIMEN HEIGHT, AND MIX GRADATION WERE STUDIED. /NAPA/
OPTIMAL DESIGN AND PERFORMANCE OF SPIRAL WOUND MODULES II: ANALYTICAL METHOD (1988)

Abstract Simple explicit equations are derived for the specific permeation rate of spiral wound modules with constant and tapered permeate channels. These have been derived by taking into account the pressure drop in the brine and permeate compartments and an effective pressure difference between the two. From them, other explicit relationships are also worked out for the evaluation of optimum thickness of the brine and permeate channels. Few error percentages arc obtained when their results are compared with those of numerical methods. Their quick and simple use make them attractive to those involved in module and plant design.
<i>The Double Helix: A Personal Account of the Discovery of the Structure of DNA</i> (1968)

In 1962 the Nobel Prize for Medicine and Physiology was awarded to Francis H.C. Crick, James D. Watson and Maurice H.F. Wilkins, the three men who, almost a decade earlier, had worked together at Cambridge, merging data from chemistry, physics and biology to solve the structure of DNA - Crick and Watson working to build a hypothetical model that would conform in all its parts to what Wilkins' X-ray pictures had already shown of the molecule. This is a reissue of the classic account of the discovery of the structure of DNA. Watson also tells of the excitement of being a young American scientist in Cambridge - how hw saw the challenge of a great discovery waiting to be made.
Mapping of Airline Reservation, Ticketing, and Messaging Traffic over IP (1998)

include any security mechanisms. The document notes that traffic can be authenticated based on external mechanisms that use static identifiers or what are apparently cleartext passwords, neither of which provide sound security. The document notes in general terms that traffic can be secured using IPSEC, but leaves this form of sound security strictly optional.
Low-Complexity Cell Search With Fast PSS Identification in LTE (2012)

Cell search and synchronization in the Third-Generation Partnership Project (3GPP) Long-Term Evolution (LTE) system is performed in each user equipment (UE) by using the primary synchronization signal (PSS) and secondary synchronization signal (SSS). The overall synchronization performance is heavily dominated by robust PSS detection, which can be achieved in the conventional noncoherent detector by exploiting the essential near-perfect autocorrelation and cross-correlation properties of Zadoff-Chu (ZC) sequences. However, a relatively high computational complexity is observed in conventional algorithms. As compared with them, two new detectors, i.e., almost-half-complexity (AHC) and central-self-correlation (CSC) detectors, are proposed in this paper to achieve reliable PSS detection with much lower complexity by exploiting the central-symmetric property of ZC sequences. The complexity of the proposed CSC detector is only 50% that of the AHC detector, which achieves exactly the same PSS detection accuracy as that of the conventional detector with one half of complexity being saved. An improvement of CSC, i.e., CSC <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Ins</sub> , is also proposed in this paper to combat the large-frequency offset. The performance of the CSC <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Ins</sub> detector is independent of the frequency offset, and numerical results show that the 90% PSS acquisition time of CSC <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Ins</sub> can be well within an 80-ms duration, even in a heavy intercell-interference environment with a signal-to-noise ratio (SNR) of -10 dB.
Analysis of the frequency stability history of GPS Navstar clocks (2002)

The two-sample Allan variance has been the standard metric for assessing the frequency stability of atomic clocks which may be characterized by nonstationary noise processes. The convergence of the Allan variance for the noise types typical of atomic clocks might appear to suggest that the variance could be estimated to an arbitrary degree of accuracy by processing more data, over longer and longer periods of time, which would lead to progressively smaller confidence intervals. This tacit assumption, however, was called into question because of the behavior of one of the Global Positioning System (GPS) on-orbit Navstar atomic clocks whose frequency stability profile exhibited significant change with the processing of additional data. Because of the peculiar nonstationary behavior of this clock, a model for the frequency stability history was developed and is now incorporated as a routine part of the analysis of Navstar clocks conducted by the Naval Research Laboratory (NRL). The frequency stability history corresponds to the output of an N-sample moving average filter operating on the sequence of squared first differences of the M-day frequency offset measurements. This procedure assumes that the stochastic process has increments whose second order properties are slowly evolving over time such that, to a reasonable approximation, it has stationary increments over the N sample-interval. Frequency stability histories are presented using from one to 120-sample averages-the number of samples averaged representing a compromise between the time resolution and the stability of the estimate. Included are frequency stability histories for both cesium and rubidium on-orbit Navstar clocks. The results indicate that the frequency stability of most of the Navstar clocks is invariant over the useful life of the clock, that the frequency stability of some of the clocks degrades over the life of the clock, and that the frequency stability of still others improves after an initial transient. The frequency stability history is now used to detect and measure degradation in the frequency stability. Significant changes in the frequency stability are reported to the GPS Master Control Station (MCS).
Misoprostol prophylaxis for high-dose chemotherapy-induced mucositis: a randomized double-blind study. (1996)

From April 1993 to September 1993, 15 patients with lymphoid or solid neoplasms underwent 16 non-cryopreserved peripheral stem cell transplantation courses using the ICE (ifosfamide, carboplatin, etoposide) program. They were randomized in a double-blind clinical trial to received oral misoprostol or placebo for mucositis prophylaxis. The active drug or placebo administration began jointly with chemotherapy at day -4 and was continued until day 16. The mucositis incidence and severity was significantly higher in patients who received misoprostol. We found no differences regarding myelosuppression, infections or other chemotherapy complications. Our results do not support the use of oral misoprostol as administered in this study, for high-dose chemotherapy-induced mucositis prophylaxis.
Topical Review: Design, Fabrication, and Applications of Hybrid Nanostructured Array (2011)

Nanohybrid materials have been widely used in the material chemistry research areas. In this paper, we mainly discussed the hybrid nanostructures used for nanobiosensor applications. It is one of the most promising and rapidly emerging research areas in nanotechnology field. Design, fabrication, and applications of hybrid nanostructures are reviewed, respectively. Finite difference time domain (FDTD) methods are applied to design different materials of hybrid nanostructures. Nanosphere lithography (NSL) is used to fabricate our designed hybrid nanostructures. Moreover, protein A and staphylococcal enterotoixn B (SEB), an enterotoxin, are detected by our designed hybrid nanostructures. From all the experiment results, we can see that our designed hybrid nanostructures are one of important nanohybrid materials. They have many potential applications in the nanobiosensor in the future.
Price Perceptions and Consumer Shopping Behavior: A Field Study (1993)

Seven price-related constructs—five consistent with a perception of price in its “negative role” and two consistent with a perception of price in its “positive role”— are used as independent variables to predict marketplace responses/behaviors in five domains: price search, generic product purchases, price recall, sale responsiveness, and coupon redemption. The price-related constructs explain a significant amount of variance in all five domains, providing evidence of predictive validity. Results of a higher order factor analysis are also reported, which provide some support for the positive-negative perception of price taxonomy.
Reconstructive surgery of the pelvis after surgery for rectal cancer (2000)

The role of the reconstructive surgeon has increased with an increasingly aggressive surgical approach to locally advanced rectal carcinoma. Multiple options exist for pelvic floor reconstruction. Muscle and myocutaneous flaps for pelvic-floor reconstruction provide well vascularized tissues which may also serve as a biologic spacer. Flaps help to prevent post-radiation fistulae, small bowel obstruction, and pelvic sidewall adherence; flaps also may serve as a barrier to radiation injury. Often a more stable perineal wound closure is achieved. In cases that involve vaginal resection, flaps make neo-vaginal reconstruction possible. Pre-operative consultation with the reconstructive surgeon allows planning of complex, multi-disciplinary procedures, and facilitates patient understanding of the proposed procedure.

Sublingual apomorphine may be a convenient means of rapidly terminating "off" periods associated with long term levodopa therapy.
Jitter testing technique and results at VC-4 desynchronizer output of SDH equipment (1995)

Specifications relative to jitter and wander generation, at the output of desynchronizer systems, represent one of the hottest topics in characterizing SDH equipment. Among the many factors involved, pointer adjustments, due to phase deviations between the received timing signal and the SDH equipment internal clock, play indeed a primary role in phase noise accumulation. This paper deals with two different kinds of test designed for measuring-from 0 Hz on-phase transients due to AU pointer adjustments, namely: static and dynamic jitter measurement configuration. Moreover, results obtained by applying this technique to different suppliers' equipment are herein presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Launched in 1994 as a not-for-profit organization, CommerceNet (http://www.commerce.net) is dedicated to advancing electronic commerce, which is fast becoming synonymous with Internet commerce. The group's nearly 250 member companies seek solutions to technology issues, sponsor numerous industry pilots, and foster market and business development.
Theoretical study of the photodissociation of low lying excited states of hydrogen peroxide (2004)

In order to explain recent photofragmentation experiments of hydrogen peroxide, the vertical excitation energies, potential-energy curves and surfaces, harmonic vibrational frequencies, and transition moments for a number of low lying excited states were calculated. The accessibility of different photodissociation channels for different excitation wavelengths was discussed, on the basis of the calculated results.
A study on the adaptation of User Participation Design for a School Space Innovation Project : focused on the Minju Plaza Project for Kunsan Sanbuk Middle School (2021)

공간은 인간생활의 필수요소 중 하나로 인간의 감정뿐만 아니라 행동에 많은 영향을 미친다. 이로 인해 오늘날의 학교공간이 학생들에게 미치는 영향에 대한 사회적 성찰의 필요성이 제기되었으며 미래교육을 위한 학교공간혁신 사업이 진행되고 있다. 이에 따라 사용자 중심의 학교공간혁신 사례를 제안 및 분석하여 실질적인 시사점을 제공하고자 한다. 본 연구의 목적 달성을 위해 사용자 참여설계와 학교공간혁신 사업의 의의를 연구하고 사용자 참여설계 프로젝트에 대한 이용자 평가 결과를 분석하였다. 이를 위해 군산산북중학교의 구성원을 대상으로 설문조사를 실시하였으며 98명의 수집된 자료는 IBM SPSS Statistics 26 프로그램을 통해 검증하였다. 그 결과 첫째, 학교공간혁신 TF팀에 참여한 구성원이 학교공간혁신 사업과 민주광장에 대해 높은 관여도를 나타냈다. 둘째, 민주광장의 공간구성요소는 높게 평가되었다. 셋째, 학교공간혁신 사업과 민주광장에 대한 관여도가 높은 집단이 낮은 집단에 비해 상대적으로 높은 이용자 만족점수를 나타냈다. 이는 사용자 참여설계가 효과적이며 향후 학교시설 환경개선에 적극 반영되어야 한다는 것을 시사한다. 더불어 이용자의 관여도를 향상시킬 수 있도록 다양한 방안을 마련한다면 미래혁신교육에 필요한 학교공간혁신의 최종 목표에 한걸음 다가설 수 있게 될 것이다.As one of the essential elements of human life, space has a great influence on not only human emotions but also actions. In this respect, with a widening perception of the social need for considering the impact of today s school space on students, a school space innovation project for future education has been launched and implemented. This study was therefore aimed at presenting and analyzing a case of user-centered school space innovation in order to derive practical implications. To this end, the significance of user participation design and the school space innovation project were studied, and user assessment results for the user participation design project were analyzed. For the analysis, a survey was conducted on the members of Kunsan Sanbuk Middle School, and the collected data from 98 persons were verified with the IBM SPSS Statistics 26 program. The followings are some findings from the analysis. First, the members who participated in the school space innovation TF team showed a high degree of involvement in the school space innovation project and the Minju Plaza project. Second, the spatial components of the Minju Plaza received high ratings from the survey respondents. Third, the group with a high involvement in the school space innovation project and the Minju Plaza project showed relatively higher user satisfaction scores than the group with a low involvement. This suggests that user participation design is effective and should be actively reflected in the improvement of school facility environment in the future. In addition, it is expected that the establishment of various measures to improve the degree of user involvement will accelerate the fulfillment of the ultimate goal of school space innovation needed for future innovation education.
Effects of Binning Parameters on Lateral and Vertical Resolution of P-S Converted Waves (1995)

Tolerances allowed in the ratio of the P-wave velocity, Vp, to the S-wave velocity, Vs (VpNS) ratio and trace dispersion within a common conversion point gather(CCP) dictate the final quality of stacked P-S converted wave sections. These parameters can affect the positioning of reflection events, the signal-to noise ratio, and the lateral and vertical resolution of subsurface images obtained from P-S converted wave data. Using synthetic and field P-S converted wave data, we evaluate the effects of varying the VpNs ratio and the dispersion within a CCP on the final quality of the stacked sections. The results show that well focused images, in comparison to corresponding P-wave images, may be obtained by the CCP gathering method. The correct positioning of the events, the IN ratio, and the resolution of the data can be preserved by careful selection of the VpNs ratio and the tolerance in trace dispersion around a central point within a CCP.

Development of Glass-Free Metal Electrically Conductive Thick Films (2000)

Air-firable glass-free metal electrically conductive thick film pastes of different compositions were developed by using a titanium alloy component, and tin and zinc metal substitutes for glass frit used in traditional thick film pastes. The effect of different components on the electrical resistivity and bonding between the thick film and the alumina substrate was investigated. Thick films with low electrical resistivity and good bonding to the alumina substrate were obtained by using silver, zinc, tin, and TiCu alloy powders in the pastes. The addition of zinc at a small proportion (<0.5 wt.%) to a thick film paste enhanced the adhesion between the thick film and the alumina substrate with negligible increase in the electrical resistivity. The use of titanium alloy powder instead of pure titanium powder is preferred. Better composition distribution, and consequently, better wetting and bonding are expected by using active metal particles of a smaller size.
