Paced Auditory Serial-Addition Task: A Measure of Recovery from Concussion (1977)

The need for a measure of severity of concussion apart from duration of post-traumatic amnesia is examined. The paced auditory serial-addition test, a measure of rate of information processing, is presented as a convenient test for estimating individual performance during recovery. Procedures for administration and control data are given, and the programme used for managing the rehabilitation of concussion patients described.
Chemical initiation of FAE clouds. Annual interim report, September 1978-September 1979 (1979)

Laboratory experiments with liquid fuel and ClF3 (CTF) or BrF3 (BTF) have suggested that an effective FAE blast may be obtained by very rapid fuel/agent dispersion and agent-induced combustion. In the current work, initial small-scale field tests using small pellets of high-explosive for fuel and agent dispersion have yielded significant FAE blasts when performed in open air, no blast when performed in an atmosphere of nitrogen, and a very strong blast when performed in an atmosphere of oxygen. The results show that an agent such as CTF meets the requirements of inducing very rapid combustion, and that the strength of the FAE blast is thus principally governed by the size and configuration of the central dispersing charge. Further small-scale tests are scheduled in which the central charge is substantially enlarged and shaped for injecting high velocity jets of fuel/agent dispersion into the surrounding atmosphere.
Stereospecific synthesis, assignment of absolute configuration, and biological activity of the enantiomers of 3-[[[3-[2-(7-chloroquinolin-2-yl)-(E)-ethenyl]phenyl][[3-(dimethylamino)-3-oxopropyl]thio]methyl]thio]propionic acid, a potent and specific leukotriene D4 receptor antagonist (1990)

The enantiomers of the leukotriene D4 antagonist 3-[[[3-[2-(7-chloroquinolin-2-yl)-(E)-ethenyl]phenyl] [[3-(dimethylamino)-3-oxopropyl]thio]methyl]thio]propionic acid (L-660,711)(MK-571) have been prepared, their absolute stereochemistry has been assigned as S for (+)-1 and R for (-)-1 by X-ray analysis of a synthetic intermediate (5), and the biological activity of the enantiomers has been explored. Unexpectedly, the enantiomers are both comparably biologically active with (+)-1 slightly more intrinsically active at the LTD4 receptor in vitro.
RNS realization of fast fixed-point multipliers with large wordlengths (2003)

The application of the residue number system (RNS) to signal processors has been widespread. In the case of infinite impulse response (IIR) digital filters, the application of the method implies the continuous scaling of the results, as in the case of autoscale multipliers. A different method of applying the RNS technique to fixed-point arithmetics was previously proposed by the authors. For this purpose, two finite arithmetics defined with respect to two different moduli were used. A case of particular interest was considered, i.e. that of 8-bit arithmetic, in which a limited amount of memory is needed to store the isomorphism tables. An extension of the above algorithm to the case of higher dynamic ranges is considered. The approach uses a radix-p representation and requires the same isomorphism tables already defined in the case of 8-b arithmetics. The algorithm thus preserves the memory requirements. If p=128 and the wordlength is 7L+1, the 8-b processor can be used as an elementary building block of the whole multiplying structure. A 22-b multiplier is considered in detail and compared to the traditional ones with respect to the time and area requirements for a VLSI realization.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
논문 : GMS - 5 인공위성 원격탐사 자료를 이용한 대기 에어러솔 모니터링 (2002)

대기중의 에어러솔은 지구복사수지에 영향을 미치는 요소이며 직·간접적인 복사강제효과로 인하여 기후변화인자로 간주되고 있다. 대기 에어러솔은 대기중 체류시간의 시·공간적 불확실성 때문에 GCM 등의 변수로 사용하기 어려운 점을 가지고 있다. 따라서 대기 에어러솔의 기후 및 대기 복사에 대한 영향을 규명하기 위하여 대기 에어러솔의 물리·광학적 성질을 밝히는 것이 필요하다. 본 연구에서는 가시영역에서의 대기효과를 분석하기 위하여 대기복사전달 모델인 MODTRAN 3 (Moderate Resolution Transmittance)의 모사결과와 GMS-5 위성의 가시영역 채널을 이용하여 황사 에어로졸의 모니터 링을 시도하였다. 본 연구에서는 황사사례를 중심으로 대기 에어러솔에 의한 대기효과를 정량화하기 위한 GMS-5 위성자료와 이를 시뮬레이션 하기 위한 MODTRAN 3 대기복사전달모델을 사용하였다. MODTRAN 3 시뮬레이션 결과로 위성의 채널 알베도와 에어러솔 광학 두께와의 관계를 계산하여 위성자료에서 에어러솔 광학두께에 관한 정보를 추출하였다. 후진 궤적분석을 통하여 황사를 포함한 공기덩어리가 고비사막으로부터 중국을 거쳐 한반도에 도달하는 것과 이때 에어러솔 광학두께가 증가하는 현상을 지상관측자료에서 확인할 수 있었다. 또한 위성 영상에서 보이는 황사영역은 황사의 이동 현상을 시간대별로 잘 나타나고 있고, 지상관측결과의 비교분석은 10% 내의 오차율을 가지는 범위 안에서 만족할 만한 결과를 보여주었다. 더욱이 같은 황사현상이 발생한 시간대에 한국, 중국과 일본에서 측정된 라이다 관측결과와 모델결과 자료는 황사 에어로졸의 특성을 잘 나타내고 있으므로 향후 대기에어로졸의 모니터링에 대한 중요한 역할을 할 수 있을 것이다.
Response surface modeling of high pressure chemical vapor deposited blanket tungsten (1991)

Chemical vapor deposited (CVD) blanket tungsten has been studied at high pressure (80 Torr) in a single-wafer cold wall reactor using response surface modeling methods. Deposition factors studied include temperature (430–490 °C), H2 partial pressure (6–30 Torr), WF6 partial pressure (1–2 Torr), and the gas inlet to wafer surface separation (200–600 mils). Quadratic models were generated for deposition rate, resistivity, sheet resistance uniformity, film stress, step coverage, reflectance, and WF6 conversion. The models were examined for consistency with previously reported results for CVD tungsten films, and were used to construct contour plots that aided a deposition process optimization search for a plug application. Optimization requirements for step coverage and sheet resistance Rs uniformity resulted in significant constraints on the usable factor space, while requirements for deposition rate, resistivity, stress, WF6 conversion, and reflectance were largely met throughout the original factor space. The resulting optimized factor space was found to be relatively large and offered additional opportunities for fine tuning of the process. Finally, data from replicated trials showed the high pressure CVD blanket tungsten process to be highly reproducible.
GaAs-Based Heterostructures on Silicon (2002)

The combination of the superior electrical and optical performance of III-V semiconductors with mature silicon technology has been very attractive for the semiconductor industry. The successful integration of the III-V compound semiconductors with silicon opens the door to many advanced electronic and optoelectronic applications. We review the recent progress on epitaxial heterostructures of oxides and GaAs-based compound semiconductors on silicon. Device quality GaAs-based heterostructures have been grown on Si substrates up to 200mm and 300mm in diameter by molecular beam epitaxy (MBE) at Motorola Labs and IQE, respectively. An epitaxial SrTiO3 (STO) layer and an amorphous interfacial layer are used as a combined buffer layer between the compound semiconductor and Si substrate. Field effect transistors (FETs) fabricated in the GaAs epi-layers show performance comparable to similar devices fabricated on GaAs substrates. The mobility in the GaAs/STO/Si sample is 2,524 cm 2 /V-s compared to a GaAs/GaAs sample with mobility of 2,682 cm 2 /V-s. A 0.7 μm gate length device has Idmax of 367 mA/mm and Gmmax of 223 mS/mm. These devices also have good RF performance with fmax of 14.5 GHz and class A power density in a 3mm device of 90 mW/mm with an associated power added efficiency of 38%. This RF performance is within experimental error of similar devices fabricated on GaAs substrates. Lifetime of these devices was also measured. After 800 hours at 200 °C, the GaAs/STO/Si sample showed 1.2% degradation in drain current.

The Impact of Children With Chronic Health Problems on Marriage (1999)

The authors examined the impact of having a child with a chronic illness or handicapping condition on marital quality and on perceived marital stability. Using data from the National Study of Families and Households (NSFH), married parents caring for a child with a chronic illness or disability (n = 94) were contrasted with married parents of well children (n = 3,693). Data were analyzed using ordinary least squares regression. Neither marital quality nor perceived marital stability differed between the two groups. These results call into question assumptions that children with special needs irreparably harm marriages.
Anticoagulation beyond direct thrombin and factor Xa inhibitors: indications for targeting the intrinsic pathway? (2013)

Antithrombotic drugs like vitamin K antagonists and heparin have been the gold standard for the treatment and prevention of thromboembolic disease for many years. Unfortunately, there are several disadvantages of these antithrombotic drugs: they are accompanied by serious bleeding problems, it is necessary to monitor the therapeutic window, and there are various interactions with food and other drugs. This has led to the development of new oral anticoagulants, specifically inhibiting either thrombin or factor Xa. In terms of effectiveness, these drugs are comparable to the currently available anticoagulants; however, they are still associated with issues such as bleeding, reversal of the drug and complicated laboratory monitoring. Vitamin K antagonists, heparin, direct thrombin and factor Xa inhibitors have in common that they target key proteins of the haemostatic system. In an attempt to overcome these difficulties we investigated whether the intrinsic coagulation factors (VIII, IX, XI, XII, prekallikrein and high-molecular-weight kininogen) are superior targets for anticoagulation. We analysed epidemiological data concerning thrombosis and bleeding in patients deficient in one of the intrinsic pathway proteins. Furthermore, we discuss several thrombotic models in intrinsic coagulation factor-deficient animals. The combined results suggest that intrinsic coagulation factors could be suitable targets for anticoagulant drugs.
North Sea Application of Seismic Correlative and Seismic Velocity (ITT) Techniques to Predict Pore Pressure (1990)

Abstract It has become extremely important in recent years to do a better job in well planning to ensure that well cost estimates and drilling programs are as complete and accurate as possible. Comprehensive well programs and realistic estimates are necessary to determine which drilling prospects are most attractive considering current upstream economics. Pore pressure analysis is the initial, and in most cases, the most important step in developing an accurate, complete well program. Casing setting depths, hole sizes, number of casing strings, mud programs, and hydraulics are examples of items in a well program which are influenced by the pore pressure profile determined for a well. Pore pressure analysis is especially critical for exploratory and delineation wells but until recently our predictive techniques were somewhat inadequate. This paper will present the application of seismic correlative and seismic velocity (ITT) techniques to predict pore pressures on a North Sea exploratory well prior to drilling. Actual mud weights used on the prospect are compared to the predicted pressures. The steps used to predict pore pressures will be discussed including sonic log pore pressure analysis correlated to the prospect, development of a regional pore pressure overlay for interval transit times, and analysis of ITT information developed from seismic shot points at the prospect and an offset well. Results from this interpretation of seismic information will be compared to the actual pressures determined after drilling the well to emphasize the effectiveness in using these techniques for pore pressure prediction.
CD43, the major sialoglycoprotein of human leukocytes, is proteolytically cleaved from the surface of stimulated lymphocytes and granulocytes. (1993)

CD43, the major sialoglycoprotein of human leukocytes, whose expression is defective in patients with the Wiskott-Aldrich syndrome, was down-regulated by phorbol 12-myristate 13-acetate (PMA) on granulocytes but not on lymphocytes. However, CD43 expressed on both of these leukocyte subpopulations was down-regulated after crosslinking by anti-CD43 monoclonal antibodies, a stimulation that may simulate the effect of a natural CD43 ligand. Soluble, labeled CD43 molecules were isolated from culture supernatants of both surface-iodinated granulocytes activated by PMA and lymphocytes stimulated with anti-CD43 antibodies. Thus, in this case down-regulation represents release from the cell surface into the culture medium, rather than internalization. The apparent molecular masses of the released molecules and of soluble CD43 isolated from human serum were identical. Importantly, PMA-induced down-regulation of CD43 on granulocytes was markedly blocked both by the metalloprotease inhibitor 1,10-phenanthroline and by the serine protease inhibitors N alpha-(p-tosyl)-L-lysine chloromethyl ketone and Pefabloc SC, which inhibit two different classes of proteases, thus indicating that the release is proteolytic.
Preparation of human albumin solder for laser tissue welding (1993)

Previous studies have demonstrated that the addition of a protein solder to augment the laser tissue weld significantly improves postoperative results. Herein we describe a method for the preparation of human albumin for use as a laser tissue solder. We also review the brief history of laser tissue solders and discuss recent advances using this technology.
Becoming a language teacher: Constraints and negotiation in the emergence of new identities (2015)

Over the past three decades, identity has become a key construct in applied linguistics and there has been a great deal of research focussing on language learner identities. Meanwhile, less research has been devoted to language teacher identities, although there has been an increase in recent years. This paper makes a modest contribution to this growing literature. It examines how two Spanish nationals developed Spanish language teacher identities while attending a Postgraduate Certificate of Education (PGCE) course at a London university.
Characterization of polymer molecular mass distribution from rheological measurements (1992)

Abstract Various methods for the determination of molecular mass distribution from rheological measurements of polymer melts are introduced. Shear viscosity, entrance pressure loss, recoverable shear, and in particular the dynamic viscoelasticity data G' and G” are discussed as analytical tools to evaluate the molecular mass distribution. Well characterized samples and homologous series of the polymers PS, PE‐HD, PP, and PTFE were measured to check the methods. Precise and reliable results can be obtained by calculating the molecular mass distribution from the frequency dependence of the storage modulus.
Photonic code-division multiple-access communications (1997)

Abstract Photonic code-division multiple access schemes have been proposed since the 1970s. Although there are many published proposals for new coding schemes, there are many less experimental verifications of these schemes, even fewer reports of successful data transmission, and no commercial systems. We attempt to explain the key factors that have led to the current state-of-the-art. In so doing, we describe the fundamental principles of matched filtering and noise in photonic CDMA schemes. We survey important developments and show how various schemes are related. We review recent experimental advances and compare the published experimental and theoretical performance for different schemes. We discuss the current major issues and likeb future directions.
Highly Efficient Synthesis of Azabicyclo[<i>x</i>.<i>y</i>.0]alkane Amino Acids and Congeners by Means of Rh-Catalyzed Cyclohydrocarbonylation (2006)

A highly efficient method for the synthesis of 1-azabicyclo[x.y.0]alkane amino acid derivatives and their congeners by means of extremely regioselective cyclohydrocarbonylation (CHC) is described. The CHC reactions are catalyzed by Rh-BIPHEPHOS complex under mild conditions. These CHC reaction processes involve (i) an extremely linear-selective hydroformylation of the terminal alkene moiety of a dehydrodipeptide substrate, (ii) intramolecular condensation to form cyclic N-acyliminium key intermediate, and (iii) the second cyclization through intramolecular nucleophilic addition of a heteoatom nucleophile to the cyclic N-acyliminium moiety to afford the corresponding 1-azabicyclo[x.y.0] system. This consecutive double cyclization process proceeds with extremely high diastereoselectivity in most cases. This method has been successfully applied to the syntheses of 1-azabicyclo[4.4.0], -[5.4.0], and -[4.3.0] systems. The mechanisms of the reactions and the rationale for the observed extremely high diastereoselectivity are presented. This Rh-catalyzed CHC process would serve as a highly efficient and versatile method for the syntheses of a variety of conformationally restrained dipeptides, peptidomimetics, alkaloids, and other biologically active natural or unnatural products.

A Novel Oxidizing Reagent Based on Potassium Ferrate(VI)<sup>1</sup> (1996)

A new, efficient preparation has been devised for potassium ferrate(VI) (K(2)FeO(4)). The ability of this high-valent iron salt for oxidizing organic substrates in nonaqueous media was studied. Using benzyl alcohol as a model, the catalytic activity of a wide range of microporous adsorbents was ascertained. Among numerous solid supports of the aluminosilicate type, the K10 montmorillonite clay was found to be best at achieving quantitative formation of benzaldehyde, without any overoxidation to benzoic acid. The roles of the various parameters (reaction time and temperature, nature of the solvent, method of preparation of the solid reagent) were investigated. The evidence points to a polar reaction mechanism. The ensuing procedure was applied successfully, at room temperature, to oxidation of a series of alcohols to aldehydes and ketones, to oxidative coupling of thiols to disulfides, and to oxidation of nitrogen derivatives. At 75 degrees C, the reagent has the capability of oxidizing both activated and nonactivated hydrocarbons. Toluene is turned into benzyl alcohol (and benzaldehyde). Cycloalkanes are also oxidized, in significant (30-40%) yields, to the respective cycloalkanols (and cycloalkanones). Thus, potassium ferrate, used in conjunction with an appropriate heterogeneous catalyst, is a strong and environmentally friendly oxidant.
Time domain attack and release modeling - applied to spectral domain sound synthesis (2008)

We introduce a time-domain model for the synthesis of attack and release parts of musical sounds. This approach is an extension of a spectral synthesis model we developed: the Parametric Synthesis Model (PSM). The attack and release model is independent from a preceeding spectral analysis as it is based on the time domain sustain part of the sound. We apply a shaping function to this sustain part to obtain the sound attack and the release. The model has been tested with linear and polynomial shaping functions and produces good results for three different instruments. The time-domain approach also overcomes the problem of synthesis artifacts that often occur when using spectral analysis/synthesis methods for sounds with transient events. Moreover, the model can be combined with any synthesis model of the sustain part and offers the possibility to determine the duration of the attack and release parts of the sound.
Balancing Message Criticality and Timeliness in IoT Networks (2019)

We study the problem of balancing timeliness and criticality when gathering data from multiple sources using a two-level hierarchical approach. The devices that generate the data transmit them to a local hub. A central decision maker then has to decide which local hubs to allocate bandwidth to and the local hubs have to prioritize the messages they transmit when given the opportunity to do so. Whereas an optimal policy does exist for this problem such a policy would require global knowledge of messages at each local hub, rendering such a scheme impractical. We propose a distributed reinforcement-learning-based approach that accounts for both the timeliness requirements and criticality of messages. We evaluate our solution using a criticality-weighted deadline miss ratio as the performance metric. The performance analysis is done by simulating the behavior of the proposed policy as well as that of several natural policies under a wide range of system conditions. The results show that the proposed policy outperforms all the other policies - except for the optimal but impractical policy - under the range of system conditions studied and that in many cases it performs close (3% to 12% lower performance depending on the condition) to the optimal policy.
Biomechanics of Knee Ligaments (1999)

Significant advances have been made during the past 25 years in characterizing the properties of ligaments as a tissue and as an individual component in the bone-ligament-bone complex. The contribution of ligaments to joint function have also been well characterized. We have presented many studies that sought to characterize the tensile and viscoelastic properties of ligaments. As a result of these investigations, some of the most important experimental and biologic factors affecting the measurements of these properties have been identified and elucidated. The identification of the tensile properties of normal ligaments can serve as the basis for evaluating their success in healing and repair after injury. Furthermore, characterization of normal ligament function is crucial for diagnosing joint injuries as well as for evaluating reconstruction strategies and developing rehabilitation protocols. The recent introduction of robotic technology to the study of joint kinematics has resulted in significant advances in the understanding of the relative importance of ligaments to joint function. With the more accurate simulation of joint kinematics that include multiple degrees of freedom motion, data on the in situ forces in ligaments can be used to improve the treatment of ligament repair and reconstruction. More complex external loading conditions that mimic sports activities and rehabilitation protocols can also be introduced in the future. Furthermore, this technology can be extended to study other frequently injured joints, such as the shoulder.
Hyperthermia and AIDS treatment (1988)

The two main clinical manifestations of AIDS are either as a series of opportunistic infections or as tumours. The most commonly observed tumour is Kaposi's sarcoma, occurring in 21% of AIDS patients in the UK (and accompanying P. carinii pneumonia in a further 7%), but other tumours, particularly non-Hodgkin's lymphoma, have also been observed in afurther 2% of patients (Alder, 1987).
