Platelet Prothrombinase Activity and Intracellular Calcium Responses in Patients With Storage Pool Deficiency, Glycoprotein IIb-IIIa Deficiency, or Impaired Platelet Coagulant Activity — A Comparison With Scott Syndrome (1997)

The procoagulant activity of platelets induced by collagen, thrombin, and collagen plus thrombin, measured as their capacity to promote the conversion of prothrombin to thrombin in the presence of factors Va and Xa, was studied in patients with α, αδ, and δ storage pool deficiency (SPD), thrombasthenia, and in two new patients with isolated defects in platelet coagulant activity, and compared with that in Scott syndrome. The most significant abnormality in the new patients, whose defect may differ from that in Scott syndrome, is an impairment in collagen plus thrombin–induced prothrombinase activity in the absence of added factor Va. In one of these patients this may be caused by an abnormality in platelet α-granule factor V distinct from that described for factor V Quebec, αδ-SPD, or α-SPD (gray platelet syndrome). Prothrombinase activity in response to all agonists was impaired in δ-SPD and was associated with an inability of these platelets to maintain elevated intracellular calcium levels. Both the rapid decline in agonist-induced [Ca2+]i levels and the impaired prothrombinase activation in δ-SPD platelets were corrected by the addition of adenosine diphosphate (ADP) after stimulation. These findings suggest that secreted ADP may play an important role in the generation of prothrombinase activity by contributing to the maintenance of a critical [Ca2+]i level necessary to maintain aminophospholipids on the outer surface of the platelet membrane, and provide evidence that dense granules may be a major source of ADP which can contribute to calcium influx in stimulated platelets. Parallel alterations, including both increases and decreases, in the [Ca2+]i and prothrombinase responses were also observed in thrombasthenia, depending on the agonist and stirring conditions. Both responses were increased in collagen-stimulated, unstirred platelets, whereas an inability to maintain increased [Ca2+]i levels, associated with decreased prothrombinase activity in all but one atypical patient, was seen in stirred collagen plus thrombin-activated platelets. Although the parallel alterations in these responses in thrombasthenia, as in SPD, further show the close association between the generation of prothrombinase activity and the maintenance of increased intracellular Ca2+ levels, the specific role that GPIIb-IIIa may play in both these events remains unresolved. Our findings of both enhancement and inhibition of these activation-related events in thrombasthenic platelets may be related to previous conflicting reports on the promotion or inhibition of fibrin formation by GPIIb-IIIa, and could be relevant to the use of specific inhibitors of GPIIb-IIIa as antithrombotic agents. In addition, the study provides further support for the concept that the development of agents that could induce a Scott syndrome defect in normal platelets may provide a new approach to antithrombotic therapy.

Representing and encoding plant architecture: A review (2000)

A plant is made up of components of various types and shapes. The geometrical and topological organisation of these components defines the plant architecture. Before the early 1970's, botanical drawings were the only means to represent plant architecture. In the past two decades, high-performance computers have become available for plant growth analysis and simulation, triggering the development of various formal representations and notations of plant architecture (strings of characters, axial trees, tree graphs, multiscale graphs, linked lists of records, object-oriented representations, matrices, fractals, sets of digitised points, etc.). In this paper, we review the main representations of plant architecture and make explicit their common structure and discrepancies. The apparent heterogeneity of these representations makes it difficult to collect plant architecture information in a generic format to allow multiple uses. However, the collection of plant architecture data is an increasingly important issue, which is also particularly time-consuming. At the end of this review, we suggest that a task of primary importance for the plant-modelling community is to define common data formats and tools in order to create standard plant architecture database systems that may be shared by research teams.

College students' acceptance of trans women and trans men in gendered spaces: The role of physical appearance (2017)

Transgender people often face prejudice and discrimination in school, employment, housing, and health care, and this can affect their psychological well-being. Although the literature on prejudice toward transgender people is growing, there is limited research that has examined differences in attitudes toward trans women and trans men separately. Specifically, the current study examined the role of physical appearance in the acceptance of transgender women and men in gendered spaces, including bathrooms, locker rooms, residence halls, and sorority and fraternity organizations. Participants viewed masculine-appearing and feminine-appearing images of a trans woman and trans man. Measurements of overall transacceptance and gendered-space acceptance were assessed. Results indicated that, in general, trans women were less accepted than trans men. The masculine-appearing trans woman was less accepted in the gendered spaces compared to the feminine-appearing trans woman and both images of the trans men. Also, female participants were generally more accepting of transgender people than male participants were. These findings suggest that, compared to trans men, discrimination of trans women is more likely, especially when the trans woman's physical appearance transgresses traditional gender expectations.
Comparative study of poly(vinyl alcohol)‐based support materials for the immobilization of glucose oxidase (2007)

Abstract BACKGROUND: The performances of four types of glucose oxidase (GOD) immobilization materials based on poly(vinyl alcohol) (PVA) were compared. The matrices of interest were chemically‐linked PVA, freeze‐thawed PVA cryogel, tetramethoxysilane (TMOS) sol‐gel‐PVA hybrid material, and alumina sol‐gel‐PVA hybrid material. RESULTS: Overall, the membranes showed good sensitivity except for the chemically cross‐linked PVA. However, the main differences with the enzyme immobilization methods were enzyme leakage and values of K m app . CONCLUSION: Freeze‐thawed PVA‐GOD membranes and TMOS‐PVA, which showed satisfactory sensitivity and adequate value of K m app , were quite promising as support materials for immobilizing GOD.

A separable Hartley-like transform in two or more dimensions (1987)

This letter introduces a discrete, separable, real-to-real transform, called the cas-cas transform. Theorems for the two-dimensional (2-D) case are presented, and the cas-cas transform is compared to the Hartley transform as an alternative way to convolve 2-D arrays and compute 2-D power spectra.
Measurement of Solid Friction Parameters of Ball Bearings (1977)

Abstract : The near static friction behavior of ball bearings and other devices can be described by the author's mathematical model of solid friction. Three or more parameters used in the model need to be defined for a particular bearing that may be employed in a motor/load system design. At present, little or no data are available to define these parameters, and there is also little or no information on the subject of test methods for obtaining solid friction model parameter data. This paper presents the results of some tests performed to measure the solid friction parameters of ball bearings. The test method is described, and typical test data are shown. The method of data reduction is based on the analytical quasi-static model and is described in some detail. Friction model parameter results are presented for a 2-1/2 in. OD duplex bearing pair with preloads in the range from 6 to 36 lb.
Enterprise logon server for domain wide web-based applications (2008)

The amplitude- and phase-frequency characteristics of oscillating bubble systems with a closed measuring cell are analyzed. The shape of the frequency characteristics is qualitatively different for bubbles smaller or larger than a hemisphere, respectively, and also for diluted and concentrated surfactant solutions. Moreover, the presence of a surfactant in the solution strongly influences the characteristic frequencies of the system. The experiments performed under ground and microgravity conditions show a good qualitative agreement with theoretically predicted amplitude- and phase-frequency characteristics and confirm the adequacy of the proposed theory. The comparison of high-frequency limits of the surface dilatational elasticity with the theoretical Gibbs elasticities calculated according to the respective adsorption isotherm shows good agreement for small surfactant concentrations. At higher concentrations large discrepancies are observed which can possibly be explained by the violation of the linearity condition for the surface layer.
두류재배 기원에 대한 고고학적 고찰 (2002)

동아시아의 고고학적 유적에서 출토된 豆類를 통하여 두류 재배의 기원문제를 살펴보고자 하였다. 한국, 일본과 중국의 기원전 유적에서 출토되는 두류는 주로 콩, 팥과 녹두이다. 신석기시대부터 야생으로 추정되는 두류가 이용되고 있지만 확실한 재배종은 기원전 1천년대의 유적에서부터 집중적으로 출토된다. 고고학적으로 보아 콩은 만주지방과 한반도에서 기원한 것으로 추정된다. 늦어도 3천년전 경에는 한반도와 길림지역의 청동기유적에서 콩이 출토되고 있는 반면 중국은 주로 前漢부터, 일본은 기원전 4세기경 이후의 야요이시대부터 발견된다. 팔도 한반도와 일본에서 먼저 출현하고 있으며 화남에는 한대부터 나타나기 때문에 한반도에서 자생하였을 가능성이 크지만 야생선조종이 확인되지 않은 상태에서는 단언하기 어렵다. 녹두는 일본에서 6천년전의 조몬 저기부터 보고되고 있으나 동정이 불확실하고 Vigna 속의 야생두류일 가능성이 높다. 확실한 녹두는 야요이유적에서 출토되며 콩, 팥과 함께 한반도에서 전래되었을 것으로 추정한다. 중국에서는 아직 녹두가 출토된 예가 없다. 두류의 재배 기원을 연구하기 위해 우선적으로 필요한 것은 두류의 정확한 동정이다. 작물학계와 고고학계의 공동적 관심이 요구된다.

Stein Variational Gradient Descent as Gradient Flow (2017)

Stein variational gradient descent (SVGD) is a deterministic sampling algorithm that iteratively transports a set of particles to approximate given distributions, based on an efficient gradient-based update that guarantees to optimally decrease the KL divergence within a function space. This paper develops the first theoretical analysis on SVGD, discussing its weak convergence properties and showing that its asymptotic behavior is captured by a gradient flow of the KL divergence functional under a new metric structure induced by Stein operator. We also provide a number of results on Stein operator and Stein's identity using the notion of weak derivative, including a new proof of the distinguishability of Stein discrepancy under weak conditions.

An Autonomic Approach to Risk-Aware Data Center Overbooking (2014)

Elasticity is a key characteristic of cloud computing that increases the flexibility for cloud consumers, allowing them to adapt the amount of physical resources associated to their services over time in an on-demand basis. However, elasticity creates problems for cloud providers as it may lead to poor resource utilization, specially in combination with other factors, such as user overestimations and pre-defined VM sizes. Admission control mechanisms are thus needed to increase the number of services accepted, raising the utilization without affecting services performance. This work focuses on implementing an autonomic risk-aware overbooking architecture capable of increasing the resource utilization of cloud data centers by accepting more virtual machines than physical available resources. Fuzzy logic functions are used to estimate the associated risk to each overbooking decision. By using a distributed PID controller approach, the system is capable of self-adapting over time-changing the acceptable level of risk-depending on the current status of the cloud data center. The suggested approach is extensively evaluated using a combination of simulations and experiments executing real cloud applications with real-life available workloads. Our results show a 50 percent increment at both resource utilization and capacity allocated with acceptable performance degradation and more stable resource utilization over time.
Applying Digital Analysis Using Benford's Law to Detect Fraud: The Dangers of Type I Errors (2005)

At first glance the application of digital analysis using Benford's Law holds great promise as a fraud detection process. However, a closer look at the underlying statistical assumptions reveals that auditors seeking to use Benford's Law must be aware of the costs of the potential Type I errors that can occur during the analysis stage. For example, statistical considerations indicate that there is a far greater chance of making a Type I error if the Benford's Law analysis is completed on a “digit-by-digit” basis, as compared to the “test-by-test” basis typically employed by statisticians. In this paper, we explain the merits of each choice in terms of statistical concepts and practical audit process considerations.
Pipeline Architecture (1977)

Pipelined computer architecture has received considerable attention since the 1960s when the need for faster and more cost-effective systems became critical. The merit of pipelining is that it can help to match the speeds of various subsystems without duplicating the cost of the entire system involved. As technology evolves, faster and cheaper LSI circuits become available, and the future of pipelining, either in a simple or complex form, becomes more promising. This paper reviews the many theoretical considerations and problems behind pipelining, surveying and comparing various representative pipeline machines that operate in either sequential or vector pipeline mode, the practical solutions adopted, and the tradeoffs involved. The performance of a simple pipe, the physical speed limitation, and the control structures for penalty-incurring events are analyzed separately. The problems faced by the system designers are tackled, including buffering, busing structur, branching, and interrupt handling. Aspects of sequential and vector processing are studied. Fundamental advantages of vector processing are unveiled, and additional requirements (costs) are discussed to establish a criterion for the tradeoff between sequential and vector pipeline processing. Finally, two recent machines (the CRAY-1 and the Amdahl 470 V/6 systems) are presented to demonstrate how complex pipeline techniques can be used and how simple but advantageous pipeline concepts can be exploited.
A high precision component-tolerant A/D convertor (1975)

A pulse transformer is used to double and sum voltages in an A/D encoder that is based on the recursive algorithm V/SUB i+1/=V/SUB REF/-s|V/SUB i/|. As a result of isolating the transformer from the input signal d.c. component, independence of circuit zero drift is achieved. Resistor and V/SUB BE/ mismatch do not affect the encoder accuracy. Automatic zero and gain correction are employed to provide stable adjustment-free operation. A custom analog processor chip carrying both MOS and bipolar transistors was fabricated to implement the algorithm. The 12-bit resolution with a maximum encoder error of 250 /spl mu/V in a temperature range from 0-70/spl deg/C was achieved at 20-kHz sampling rate.
A Large Area Tactile Sensor Patch Based on Commercial Force Sensors (2011)

This paper reports the design of a tactile sensor patch to cover large areas of robots and machines that interact with human beings. Many devices have been proposed to meet such a demand. These realizations are mostly custom-built or developed in the lab. The sensor of this paper is implemented with commercial force sensors. This has the benefit of a more foreseeable response of the sensor if its behavior is understood as the aggregation of readings from all the individual force sensors in the array. A few reported large area tactile sensors are also based on commercial sensors. However, the one in this paper is the first of this kind based on the use of polymeric commercial force sensing resistors (FSR) as unit elements of the array or tactels, which results in a robust sensor. The paper discusses design issues related to some necessary modifications of the force sensor, its assembly in an array, and the signal conditioning. The patch has 16 × 9 force sensors mounted on a flexible printed circuit board with a spatial resolution of 18.5 mm. The force range of a tactel is 6 N and its sensitivity is 0.6 V/N. The array is read at a rate of 78 frames per second. Finally, two simple application examples are also carried out with the sensor mounted on the forearm of a rescue robot that communicates with the sensor through a CAN bus.
The Transcriptional Switch of Bacteriophage WΦ, a P2-Related but Heteroimmune Coliphage (1999)

Phage WPhi is a member of the nonlambdoid P2 family of temperate phages. The DNA sequence of the whole early-control region and the int and attP region of phage WPhi has been determined. The phage integration site was located at 88.6 min of the Escherichia coli K-12 map, where a 47-nucleotide sequence was found to be identical in the host and phage genomes. The WPhi Int protein belongs to the Int family of site-specific recombinases, and it seems to have the same arm binding recognition sequence as P2 Int, but the core sequence differs. The transcriptional switch contains two face-to-face promoters, Pe and Pc, and two repressors, C and Cox, controlling Pe and Pc, respectively. The early Pe promoter was found to be much stronger than the Pc promoter. Furthermore, the Pe transcript was shown to interfere with Pc transcription. By site-directed mutagenesis, the binding site of the immunity repressor was located to two direct repeats spanning the Pe promoter. A point mutation in one or the other repeat does not affect repression by C, but when it is included in both, C has no effect on the Pe promoter. The Cox repressor efficiently blocks expression from the Pc promoter, but its DNA recognition sequence was not evident. Most members of the P2 family of phages are able to function as helpers for satellite phage P4, which lacks genes encoding structural proteins and packaging and lysis functions. In this work it is shown that P4 E, known to function as an antirepressor by binding to P2 C, also turns the transcriptional switch of WPhi from the lysogenic to the lytic mode. However, in contrast to P2 Cox, WPhi Cox is unable to activate the P4 Pll promoter.
OISE Conference on Bilingual Education (1971)

One of the most exciting recent developments in education, and an innovation which has considerable bearing o n second language teaching in the schools, is the so-called 'French immersion program', or 'Home-School Language Switch'. This type of schooling aims to promote functional bilingualism in its students through a program of bilingual education. What, in fact, constitutes a bilingual education program ? It implies the use of the second language , in this case French, as a medium of instruction o r as a means of communication. I n other words, fostead of formal instruction of the target language, o r in addition to it, bilingual education provides for the functional use of the second language within the school, A bilingual education program, therefore, can be defined as schooling for English-speaking children, provided fully or partly through the medium of French, with the objective of making these children highly proficient in French while maintaining and develoving their vroficiency in English, and fully guaranteeing their general educational develovment.
Analysis and simulation of domain propagation in nonuniformly doped bulk GaAs (1969)

A study of domain behavior in nonuniformly doped bulk semiconductor devices is undertaken, leading to a simple graphical technique useful for the analysis of these structures. Several device configurations are treated in this fashion and further examined with the aid of a digital computer program written by the author for simulation of the bulk effect in n-GaAs. The operation of these devices is illustrated with computer-generated graphic displays of electric field, carrier distribution, and device current as a function of time.
Efficient and secure encryption schemes for JPEG2000 (2004)

The JPEG2000 syntax requires that any two consecutive bytes in the encrypted packet body should not be larger than 0xFF8F. This stringent requirement has plagued researchers for a few years and no satisfactory solution has been proposed. In this paper, we successfully developed efficient, secure and format-compliant encryption schemes for JPEG 2000. Any secure encryption algorithm (stream cipher or block cipher) can be used in our schemes. The new schemes are remarkably efficient and introduce only an extremely small amount of extra computation. The new schemes are highly secure and it is proved that they perfectly protect 99.15% of the information of an image. The encryption tools described in this paper have been proposed to the JPSEC (JPEG 2000 Security) standardization group.
