Diurnal Variation of the Fibrinolytic System

Abstract To elucidate which component(s) of thei fibrinolytic system is (are) responsible for the diurnal variation of fibrinolytic activity we have studied several parameters of this system in 8 healthy male volunteers during a period of. 24 h. Blood was collected at 8 a. m. , 10 a. m. , 12 a. m. , 4 p.m. , 8 p.m. and 8 a. m. next morning. The following tests were performed: euglobulin clot lysis time (ECLT), fibrinolytic activity of euglobulins on fibrin plates in the presence and absence of blocking antibodies to tissue-type plasminogen activator (t-PA) and/or urokinase (u-PA), overall plasminogen activator inhibitor (PAI) activity, antigen levels of t-PA, u-PA and PAI-I and zymography of the euglobulin fraction after SDS-PAGE. From 8-10 a. m. to 4-8 p. m. , total fibrinolytic activity increased by 1l3% (p <0.01) or 71%h (p <0.01) when measured by ECIX or by fibrin plate assay, respectively. The immunoquenching experiments showed that this increase was entirely due to t-PA related activity whereas u-PA activity and t-PA/u-PA independent activity remained constant during the day. Average antigen levels of u-PA and t-PA in the afternoon were 6% and 25% lower than those measured in the morning. During this period, overall PAI activity and PAI-1 antigen decreased by 3l% (p <0.01) and 52% (p <0.01) respectively. Electrophoretic-zymographic analysis of_ the euglobulins revealed that throughout the day the majority of t-PA was present in the form of the 110 kDa t-PA/PAI-I complex. The intensity of this cornplex was lowest in the afternoon. Free t-PA was almost undetectable in morning samples, but constituted a significant proportion of total t-PA in the afternoon. The diurnal increase of fibrinolytic activity, therefore, is not due to an augmentation of antigen levels of t-PA and/or u-PA but to a decline of those of PAI-1.
Do User Entrepreneurs Speak Different?: Applying Natural Language Processing to Crowdfunding Videos

In this work, we analyze video pitches of creators in crowdfunding campaigns and focus on linguistic particularities of "lead user" entrepreneurs. Theory suggests that lead users sense needs long before they become known to the broader public and would benefit greatly from finding a solution to these needs. For our study, we consider 537 video pitches of creators on Kickstarter, distinguishing lead users and regular campaigners. The study employs natural language processing (NLP) analysis of (video-to-)speech-to-text content. Initial results indicate that lead users are more oriented towards product and problem-solving rather than focusing on pecuniary motives.
IEEE 802 . 11 Rate Control Algorithms : Experimentation and Performance Evaluation in Infrastructure Mode

This paper evaluates the performance of practical Rate Control Algorithms (RCAs) operating at the Media Access Control (MAC) layer in IEEE 802.11 networks built on Atheros chipsets. Using a dual band 32bit cardbus based wireless network interface card (WNIC) on a laptop running vanilla Linux 2.6. 13.3 kernel, we explore the capabilities of each of the three different RCAs under varying wireless channel conditions. We observe their link layer response by using a closely monitored and controlled step function generated inside a microwave operating at 2450 MHz. The resultant link layer performance is quantified by the Kullback-Leibler (KL) distance that exposes the degree of divergence between the received signal strength indicator (RSSI) distribution and that of the adapted transmission rate. Our findings indicate that both Adaptive Multi Rate Retry (AMRR) algorithm and SampleRate are sensitive enough to detect short term variations of RSSI values while Onoe is practically immune to such short term signal strength variations. In order to expose the effect of RCA on application layer, we conducted experiments with heterogeneous traffic (Voice, Streaming, Interactive, Background) in controlled network subnets. The average application level throughput, packet inter-arrival time and jitter observed with different RCAs is reported in our study. Our experiments show that the aggressive adaptation behavior of AMRR and SampleRate to RSSI variations does not bode well for delay sensitive traffic like VoIP applications. The conservative Onoe is more suitable in such cases. However, for other traffic types, both AMRR and SampleRate compete neck-and-neck in providing high application throughput.
An adaptive fuzzy logic controller: its VLSI architecture and applications

Most previous work about the hardware design of a fuzzy logic controller (FLC) intended to either improve its inference performance for real-time applications or to reduce its hardware cost. To our knowledge, there has been no attempt to design a hardware FLC that can perform an adaptive fuzzy inference for the applications of on-line adaptation. The purpose of this paper is to present such an adaptive memory-efficient FLC and its applications. Taking advantage of the adaptability provided by a symbolic fuzzy rule format and the dynamic membership function generator, as well as the high-speed integration capability afforded by VLSI, the proposed adaptive fuzzy logic controller (AFLC) can perform an adaptive fuzzy inference process using various inference parameters, such as the shape and location of a membership function, dynamically and quickly. Three examples are used to illustrate its applications, and the experimental results show the excellent adaptability provided by AFLC.
In-cloud oxalate formation in the global troposphere: a 3-D modeling study

Organic acids attract increasing attention as contributors to atmospheric acidity, secondary organic aerosol mass and aerosol hygroscopicity. Oxalic acid is globally the most abundant dicarboxylic acid, formed via chemical oxidation of gas-phase precursors in the aqueous phase of aerosols and droplets. Its lifecycle and atmospheric global distribution remain highly uncertain and are the focus of this study. The first global spatial and temporal distribution of oxalate, simulated using a state-of-the-art aqueous-phase chemical scheme embedded within the global 3-dimensional chemistry/transport model TM4-ECPL, is here presented. The model accounts for comprehensive gas-phase chemistry and its coupling with major aerosol constituents (including secondary organic aerosol). Model results are consistent with ambient observations of oxalate at rural and remote locations (slope = 1.16 ± 0.14, r2 = 0.36, N = 114) and suggest that aqueous-phase chemistry contributes significantly to the global atmospheric burden of secondary organic aerosol. In TM4-ECPL most oxalate is formed in-cloud and less than 5 % is produced in aerosol water. About 62 % of the oxalate is removed via wet deposition, 30 % by in-cloud reaction with hydroxyl radical, 4 % by in-cloud reaction with nitrate radical and 4 % by dry deposition. The in-cloud global oxalate net chemical production is calculated to be about 21-37 Tg yr−1 with almost 79 % originating from biogenic hydrocarbons, mainly isoprene. This condensed phase net source of oxalate in conjunction with a global mean turnover time against deposition of about 5 days, maintain oxalate's global tropospheric burden of 0.2-0.3 Tg, i.e. 0.05-0.1 Tg-C that is about 5-9 % of model-calculated water soluble organic carbon burden. © 2011 Author(s).
Trust Based Access Control Policy in Multi-domain of Cloud Computing

Cloud computing is a new paradigm which enables users to reduce their costs and is advantageous to both the serving and served organizations. However, security issue is a major concern in the adoption of cloud computing. The most effective way of protecting cloud computing services, resources and users is access control. This paper intends to provide a trust-based access control mechanism for cloud computing considering its multi-domain aspects. Firstly, trust is introduced into cloud computing environment and trust relationships between users and cloud platform are built. It also analyzes the difference between intra-domain trust and inter-domain trust. Furthermore, a role-based access control framework combined with trust degree in multi-domain is given from this paper. Access control in local domain directly applies RBAC model combined with trust degree, whereas in multi-domain it contains the conception of role translation. The simulation results show that the proposed method is more suitable to cloud environment and definitely can improve the reliability and validity of the system.
Historical Self-Comparison of Water Consumption as a Water Demand Management Tool

This study aimed to identify effective presentation methods used for historical self-comparisons of residential water consumption that will lead to the efficient use of water. To compare each household’s current and previous water consumption, illustrations of water droplets were used as feedback every other week for five months, with the number of water droplets indicating an increase or decrease in water consumption. When only using the same blue water droplets, there was no change in water consumption. However, when using yellow and red droplets in cases of increased water use, we observed that water consumption declined. By improving the method of communication, historical self-comparisons of water consumption can realize an efficient use of water at all consumption levels.
A graph-theoretic approach to webpage segmentation

We consider the problem of segmenting a webpage into visually and semantically cohesive pieces. Our approach is based on formulating an appropriate optimization problem on weighted graphs, where the weights capture if two nodes in the DOM tree should be placed together or apart in the segmentation; we present a learning framework to learn these weights from manually labeled data in a principled manner. Our work is a significant departure from previous heuristic and rule-based solutions to the segmentation problem. The results of our empirical analysis bring out interesting aspects of our framework, including variants of the optimization problem and the role of learning.
Coaching for Wisdom: Enabling Wise Decisions

What the world needs now . is wise leadership! Now, more than ever, our collective fate rests in the hands of leaders who decide and act either wisely or foolishly. Masterful coaching has the potential to both enable and ennoble leaders for our sustainable common good. Wisdom, according to the late American historian Barbara Tuchman (1984), is ‘the exercise of judgment acting on experience, common sense and available information’. Anything less is ‘folly. ’ And folly in leadership is as pervasive now as it ever was. ‘Know my son, with how little wisdom the world is governed,’ advised Count Axel Oxenstierna, Chancellor of Sweden, 1632-1644, during the Thirty Years’ War (Tuchman, 1984). There is no doubt we want our leaders to have more rather than less wisdom when it comes to making difficult decisions affecting our lives. But how do we know who is wise and what a wise decision is? In the rapidly changing environment of both commercial and government enterprises what seems a wise thing to do today can easily be deemed folly over time, and often within a very short time.
Paraphyly in Hawaiian hybrid blowfly populations and the evolutionary history of anthropophilic species

Complementary nuclear (28S rRNA) and mitochondrial (COI + II) gene markers were sequenced from the blowflies, Lucilia cuprina and Lucilia sericata, from Europe, Africa, North America, Australasia and Hawaii. Populations of the two species were phylogenetically distinct at both genes, with one exception. Hawaiian L. cuprina possessed typical L. cuprina‐type rRNA, but had L. sericata‐type mitochondrial (COI + II) sequences. An explanation for this pattern is that Hawaiian flies are hybrids and comparison of observed levels of sequence divergence to possible introduction events, e.g. Polynesian colonization, suggests that Hawaiian L. cuprina may be evolving rapidly. Moreover, the monophyly of these flies also suggests that the L. sericata mtDNA haplotype was apparently fixed in Hawaiian L. cuprina by lineage sorting, indicating a population bottleneck in the evolutionary history of these island flies.
A steerable complex wavelet construction and its application to image denoising

This work addresses the design of a novel complex steerable wavelet construction, the generation of transform-space feature measurements associated with corner and edge presence and orientation properties, and the application of these measurements directly to image denoising. The decomposition uses pairs of bandpass filters that display symmetry and antisymmetry about a steerable axis of orientation. While the angular characterization of the bandpass filters is similar to those previously described, the radial characteristic is new, as is the manner of constructing the interpolation functions for steering. The complex filters have been engineered into a multirate system, providing a synthesis and analysis subband filtering system with good reconstruction properties. Although the performance of our proposed denoising strategy is currently below that of recently reported state-of-the-art techniques in denoising, it does compare favorably with wavelet coring approaches employing global thresholds and with an "Oracle" shrinkage technique, and presents a very promising avenue for exploring structure-based denoising in the wavelet domain.
Processes Contributing to the Maintenance of Flying Phobia: A Narrative Review

Flying phobia is a highly prevalent anxiety disorder, which causes sufferers significant distress and life interference. The processes which maintain flying phobia remain poorly understood. A systematic search of the literature was performed to identify what research has been conducted into the processes which may be involved in the fear of flying and whether processes which are believed to maintain other anxiety disorder diagnoses have been investigated in flying phobia. The results of the literature review are presented and related to existing cognitive behavioral theory and research. The results indicate that little research has been conducted into a number of areas considered important in the wider cognitive behavioral literature on anxiety disorders: namely attention, mental imagery, memory, worry, and safety-seeking behaviors. The review proposes a hypothetical model, derived from cognitive behavioral theory, for the processes which may be involved in maintaining flying phobia, and considers a number of areas for future research.
An Analytical Expression for k-connectivity of Wireless Ad Hoc Networks

Over the last few years coverage and connectivity of wireless ad hoc networks have fascinated considerable attention. The presented paper analyses and investigates the issues of k-connectivity probability and its robustness in wireless ad hoc-network while considering fading techniques like lognormal fading, Rayleigh fading, and nakagami fading in the ad hoc communication environment, by means of shadowing and fading phenomenon. In case of k-connected wireless sensor network (WSNs), this technique permits the routing of data packets or messages via individual (one or more) of minimum k node disjoint communication paths, but the other remaining paths can also be used. The major contribution of the paper is mathematical expressions for k-connectivity probability.
Project Kittyhawk: building a global-scale computer: Blue Gene/P as a generic computing platform

This paper describes Project Kittyhawk, an undertaking at IBM Research to explore the construction of a next-generation platform capable of hosting many simultaneous web-scale workloads. We hypothesize that for a large class of web-scale workloads the Blue Gene/P platform is an order of magnitude more efficient to purchase and operate than the commodity clusters in use today. Driven by scientific computing demands the Blue Gene designers pursued an aggressive system-on-a-chip methodology that led to a scalable platform composed of air-cooled racks. Each rack contains more than a thousand independent computers with highspeed interconnects inside and between racks. We postulate that the same demands of efficiency and density apply to web-scale platforms. This project aims to develop the system software to enable Blue Gene/P as a generic platform capable of being used by heterogeneous workloads. We describe our firmware and operating system work to provide Blue Gene/P with generic system software, one of the results of which is the ability to run thousands of heterogeneous Linux instances connected by TCP/IP networks over the high-speed internal interconnects.
Long‐term follow‐up of five yr shows superior renal function with everolimus plus early calcineurin inhibitor withdrawal in the PROTECT randomized liver transplantation study

The 12‐month (M) PROTECT study showed that de novo liver transplant recipients (LTxR) who switched from a calcineurin inhibitor (CNI)‐based immunosuppression to a CNI‐free everolimus (EVR)‐based regimen showed numerically better renal function. Here, we present the five‐yr follow‐up data.
Perceived social support and work-family conflict

Purpose – Despite the abundance of research on work social support and work-family conflict, the generalizability of these relationships to immigrant and non-immigrant Hispanics is still unknown. Based on role and cultural theories, the purpose of this paper is to provide an empirical examination of these relationships within this growing yet understudied population. Design/methodology/approach – Survey data were collected from a diverse sample of employed immigrant and non-immigrant Hispanics from a broad set of occupational groups within Miami, Florida (USA). Structural equation modeling (SEM) was used to test hypotheses. Multi-group analyses were conducted to test for differences in model fit and parameter estimates between the immigrant and non-immigrant subgroups. Findings – The hypothesized model fit the data well, with a significant positive relationship between perceived organizational social support and perceived supervisor social support, a significant negative relationship between perceived org.
Mitigating the misbehavior of nodes at MAC layer in wireless ad hoc network

In wireless ad hoc networks, misbehavior of nodes in computation of backoff value is one of the problems that affects the performance at MAC layer. To overcome this problem, this paper proposes a solution in which Contention Window subrange is specified by the receiver to the sender through CTS/ ACK packet. The advantage of sending the Contention Window subrange is, it is easier to detect the misbehaving nodes. From the simulation results, it can be inferred that the proposed solution reduces the misbehavior of the nodes.
A Partial IR Hybrid ARQ Scheme Using Rate-Compatible Punctured LDPC Codes in an HSDPA System

SUMMARY In this paper, an efficient partial incremental redundancy (P-IR) scheme is proposed for an H-ARQ using block type low density parity check (B-LDPC) codes. The performance of the proposed P-IR scheme is evaluated in an HSDPA system using IEEE 802.16e B-LDPC codes. Simulation results show that the proposed H-ARQ using IEEE 802.16e BLDPC codes outperforms the H-ARQ using 3GPP turbo codes.
Cognitive Referencing

The article questions the appropriateness of using cognitive referencing as a method to determine children's eligibility for language and motor services. Theoretical assumptions underlying the model are reviewed, and the validity of the practice is examined in light of current theory and empirical evidence. We conclude that the model of cognitive referencing is not consistent with current theoretical formulations. In addition, empirical findings examining the validity of the practice do not give support to the model. We caution practitioners against the adoption of a model that results in the exclusion of children from services until more thorough empirical examination is available on the appropriateness of the practice.
Variations in human cortical response to patterns and image quality.

Selective excitation of the human visual cortex by patterned stimuli was examined in a randomly selected sample of normal adtdts and adults with severe monocular visual loss resulting from childhood strabismic amblyopia. Six of the eight normal eyes showed selective but variable configuration cortical evoked responses (VER, passband 0.2 to 50 Hz.) to patterned stimulation when lenses were used to vary the retinal focus. The remainder of the normal sample also showed response peaks where resolution was maximum, but these were in the signal passband 50 to 500 Hz. , previously called the fast occipital potential (FOP). We applied normalizing signals to correct for individual response variations. Statistical proofs indicated that this procedure reduced variability about mean results. Two of the three amblyopic eyes produced no response peak, VER or FOP, at the refractive value for best resolution. A small VER peak was found in one amblyopic subject who had eccentric fixation. Subtraction of mean nonpattern from pattern-evoked signals at optimal refraction disclosed a cortical signal which may be a relatively "pure pattern" response. As a clinical aid, the VER and its high frequency correlate, the FOP, appear to provide an objective test of the resolving power of the visual system with accuracy equal to or exceeding 0.5 D. sphere.
PREDICTION OF DISEASE STATUS: TRANSITION MODEL APPROACH FOR REPEATED MEASURES

This paper develops models for prediction of disease status from longitudinal data. The estimation of area under curve (AUC) is illustrated on the basis of estimates of sensitivity and specificity for repeated binary outcomes of disease status. There are several research papers in this field on cross-sectional data but only a few dealt with the repeated observations. This paper shows the procedures to deal with repeated observations employing Markov models. These procedures employ covariate dependent Markov models for estimating sensitivity and specificity, which in turn, produce the estimates for area under curve. The tests for equality of areas under curve for two models are also suggested. An application is illustrated for depression data from the Health and Retirement Survey, USA. The results indicate that the transition model approach can reveal the matching of disease status very efficiently; an estimate of more than 0.96 was obtained for the AUC for a transition model based prediction of disease from the depression data.
In The Eye of the Beholder: The Relationship between Intern Effectiveness, Satisfaction, and Job Characteristics

Faculty and site supervisors hope that the internships they provide to undergraduate students afford a valuable learning experience that bridge the gap between classroom learning and application. However, little empirical research has measured the components of an effective internship experience. In this study, the authors examined the relationship between internship job characteristics and interns’ performance and satisfaction from two perspectives: the site supervisor and the intern. At the conclusion of their internship, 159 student interns and their site supervisors completed an adaptation of the Job Diagnostic Survey, and supervisors rated intern performance. The results suggest that job characteristics are in the eye of the beholder; that is, supervisors and interns viewed the intern’s work differently. For example, supervisors reported that they believed that the interns were more satisfi ed and that they learned more about their career direction than did the interns themselves. Core job characteristics and contextual variables were associated with intern satisfaction, but supervisors and interns perspectives differed with respect to performance. Compared to their supervisors, students reported that their internships possessed more task identifi cation and allowed for more co-worker support. Most of the core job characteristics and several contextual variables as seen by the supervisor were related to intern performance. From the students’ perspective, only task feedback and few contextual variables were associated with performance. From both the
