Sick Sinus Syndrome after Surgery for Congenital Heart Disease

The course and prognosis of 16 infants and children with sick sinus syndrome associated with cardiac surgery is reviewed. The dysrhythmia was observed most often after extensive atrial reconstructive surgery in patients with transposition of the great arteries and with atrial septal defect. In 12 (75%) of the patients, sick sinus syndrome was detected in the immediate postoperative period. Tachyarrhythmias and bradyarrhythmias were present in 12 and isolated bradyarrhythmias in four. Temporary pacing was used in two and permanent pacing was required in five. Death in two non-paced patients was attributable to arrhythmias. Postmortem examination in one patient revealed a suture in the sinoatrial node. Careful attention to the anatomy of the sinoatrial node, its artery and the internodal tracts during surgery may prevent the development of sick sinus syndrome. In patients with dysrhythmia, a careful search should be undertaken to document the abnormal rhythm with the use of Holter monitoring. The insertion of a pacemaker is indicated in patients with tachyarrhythmias requiring cardioversion or antiarrhythmic drug therapy and those without adequate lower escape mechanisms.
Correlating Twitter with the stock market through non-Gaussian SVAR

In this paper, we aim at studying the correlation between Twitter and the stock market. Specifically, we first apply non-Gaussian SVAR (structural vector autoregression) to identify possible relationships among the Twitter and stock market factors. Compared with conventional models such as Granger causality method which assume that the error items are Gaussian and only consider time-lag effect, non-Gaussian SVAR is under the assumption that the error items are non-Gaussian, better fitting the data in the stock market, and takes both instantaneous and time-lagged effects into account. We also visualize some distinctive relationships in parallel coordinates which is a well-developed multivariate visualization technique but seldom used in financial studies to the best of knowledge. Then, with the purpose of examining whether the Twitter-stock market relationship returned by non-Gaussian SVAR can help predict the stock market indicators, we build a series of regression models to predict DJI (Dow Jones Industrial Average Index) return in a sliding time window. Our experiments demonstrate that all the Twitter factors correlate with DJI return, and only the negative sentiment in tweets (posts on Twitter) is associated with DJI return volatility. Moreover, the lagged Twitter factors are more effective than the lagged stock market indicators in terms of predicting DJI return in the period of our data set.
The Papain-Like Protease from the Severe Acute Respiratory Syndrome Coronavirus Is a Deubiquitinating Enzyme

ABSTRACT The severe acute respiratory syndrome coronavirus papain-like protease (SARS-CoV PLpro) is involved in the processing of the viral polyprotein and, thereby, contributes to the biogenesis of the virus replication complex. Structural bioinformatics has revealed a relationship for the SARS-CoV PLpro to herpesvirus-associated ubiquitin-specific protease (HAUSP), a ubiquitin-specific protease, indicating potential deubiquitinating activity in addition to its function in polyprotein processing (T. Sulea, H. A. Lindner, E. O. Purisima, and R. Menard, J. Virol. 79:4550-4551, 2005). In order to confirm this prediction, we overexpressed and purified SARS-CoV PLpro (amino acids [aa]1507 to 1858) from Escherichia coli. The purified enzyme hydrolyzed ubiquitin-7-amino-4-methylcoumarin (Ub-AMC), a general deubiquitinating enzyme substrate, with a catalytic efficiency of 13,100 M−1s−1, 220-fold more efficiently than the small synthetic peptide substrate Z-LRGG-AMC, which incorporates the C-terminal four residues of ubiquitin. In addition, SARS-CoV PLpro was inhibited by the specific deubiquitinating enzyme inhibitor ubiquitin aldehyde, with an inhibition constant of 210 nM. The purified SARS-CoV PLpro disassembles branched polyubiquitin chains with lengths of two to seven (Ub2-7) or four (Ub4) units, which involves isopeptide bond cleavage. SARS-CoV PLpro processing activity was also detected against a protein fused to the C terminus of the ubiquitin-like modifier ISG15, both in vitro using the purified enzyme and in HeLa cells by coexpression with SARS-CoV PLpro (aa 1198 to 2009). These results clearly establish that SARS-CoV PLpro is a deubiquitinating enzyme, thereby confirming our earlier prediction. This unexpected activity for a coronavirus papain-like protease suggests a novel viral strategy to modulate the host cell ubiquitination machinery to its advantage.
Psycholinguistic Abilities in Learning-Disabled, Emotionally Disturbed, and Normal Children

1This investigation was supported in part by projects 427, 912, and 918 from the Maternal and Child Health Service; Health Services Mental Health Grant HD-00324 from the National Institute of Child Health and Human Development; the State of Ohio Department of Health; and the National Foundation March of Dimes. The use of the concept &dquo;minimal brain dysfunction&dquo; to explain learning and behavior disabilities has increased, despite theoretical inadequacies and difficulties in definition by (Clements, 1966). A large number of special classes for children diagnosed as having &dquo;minimal brain dysfunction&dquo; or &dquo;minimal neurological handicaps&dquo; have been established; these are frequently called &dquo;learning-disabilities&dquo; (LD) classes.
Using Photographs to Research Organizations: Evidence, Considerations, and Application in a Field Study

Despite calls for more visual methodologies in organizational research, the use of photographs remains sparse. Organizational research could benefit from the inclusion of photographs to track contemporary change processes in an organization and change processes over time, as well as to incorporate diverse voices within organizations, to name a few advantages. To further understanding, the authors identify researcher choices related to the use of photographs in organizational research, clarify the advantages and disadvantages of these choices, and discuss ethical and other special considerations of the use of photographs. They highlight several organizational areas of research, primarily related to the management discipline, that could benefit from the inclusion of photographs. Finally, the authors describe how they used photographs in a study of one organization and specifically how their intended research design with photographs changed over the course of the study as well as how photographs helped to develop new theoretical insights. Photographic research methods represent a viable—but underleveraged—method that should be more fully incorporated in the methodological tool kit of organizational scholars.
Beyond the barricades: Social movements as participatory practice in health promotion

Community-based health promotion has focussed on empowering disadvantaged groups, but there is growing awareness of the need to address everyday practices used to maintain power and privilege across social divisions. Participatory Action Research projects have proved subject to problems of resistance from dominant social groups. Social movements seeking to reshape power relations, give voice to excluded people and promote a social environment in which their problems are understood have been suggested as an alternative approach. A model of social movements based on theories and observations of social movement dynamics offers a practical framework for initiating such social change.
Architectural Support for 3D Graphics in the Complex Streamed Instruction Set

In this paper we extend the previously proposed Complex Streamed Instruction Set (CSI) architecture to provide for floating-point computations and conditional execution in order to efficiently support 3D graphics applications. The CSI extension is evaluated using an industry standard 3D benchmark, and compared to the Intel’s Streaming SIMD Extension (SSE). Compared to a 4-way issue superscalar processor extended with SSE and capable of processing 8 single-precision floating-point operations in parallel, the same processor extended with CSI attains the speedups of 2.8 and 2.13 on the transform and lighting kernels and the speedup of 1.61 on the geometry computations in whole. We also study how performance scales with the number of floating-point units and observe that CSI extension allows to utilize them more efficiently then SSE. Finally, the performance bottlenecks of the SSEenhanced superscalar CPUs on the 3D graphics workload are identified. Results show that performance of the 4-way issue machines is limited by the issue width and that of the 8-way machines is limited by the number of the cache ports.
The Effects of Crisis Response Strategies on Relationship Quality Outcomes

This study investigated the effects of crisis response strategies on the attribution of an organization’s crisis responsibilities and relationship quality outcomes and determined the linkages among relationship quality outcome indicators. This study found that none of the tested crisis response strategies were helpful in reducing public blame surrounding the featured organization’s responsibility in the crisis. This study also found that the presence of crisis itself tends to negatively affect the relationship quality and that the publics examined were not influenced by the use of crisis response strategies.
Better Than Expected: Using Learning Analytics to Promote Student Success in Gateway Science

Change • January/February 2014 By Mary C. Wright, Timothy McKay, Chad Hershock, Kate Miller, and Jared Tritz Learning Analytics (LA) has been identified as one of the top technology trends in higher education today (Johnson et al., 2013). LA is based on the idea that datasets generated through normal administrative, teaching, or learning activities—such as registrar data or interactions with learning management systems—can be analyzed to enhance student learning, academic progress, and teaching practice. Examples of LA projects in colleges and universities include Purdue University’s “Course Signals” system, an early-alert notification for struggling students, and Austin Peay State University’s “Degree Compass,” a course recommender program based on predictive analytics.
Issues of representation, reflexivity, and research-participant relationships: Doing feminist cultural studies to improve health campaigns

I reflect upon findings from a feminist cultural study uncovering teen girls’ and parents’ perceptions of the Gardasil HPV/cervical cancer vaccine media campaign. I consider issues important to feminist researchers such as representation, reflexivity, and researcher–participant relationships as they relate to public relations research. Topics discussed are seeing the dark side of meeting our publics, renegotiating feminist ideals, and balancing strategic and feminist goals. I propose considerations for doing feminist cultural studies to inform campaign production.
An Essay to Characterise Information Fusion Systems

Characterisation of an information fusion system (IFS) is a very difficult challenge. There are many levels of information fusion and there are many decision fusion models. One can argue that each problem is very specific and thus developing a generalized framework is utopia. This paper presents a simplified, and sometimes naive representation of IFS. This representation is based on characterising the inputs and outputs of IFS. An IFS is thus seen as a function that transforms the input into an output given some conditions. These conditions might include controls, background knowledge, and goals queries. We present a set of properties that might be considered to characterise a fusion function. This paper also discusses some challenges of distributed information fusion as a pre-requisite of Net-enabled operations
A Cultural–Historical Approach to Mind

Accessible online at: http://BioMedNet.com/karger This book opens with a presentation of Scribner’s life history written by her daughter. The presentation gives much more than a biography; it gives a background for understanding a recurrent pattern in Scribner’s research studies. In most of her research the object of study has been the interaction of historical and societal conditions in different institutional settings for humans’ social and mental functioning and development. This pattern functions as a common core for understanding the diversity in Scribner’s research projects. Her daughter describes her mother’s fondness for literacy starting at an early age: ‘At a young age Sylvia became enamored with the written word, a theme threaded throughout her life, and she started writing poetry when she was seven’ (p. XX). Several of Scribner’s poems are presented throughout the book, giving us a condensed sense of a person questioning the relation between mind and cultural practice. To understand a person’s mind one has to understand the social and historical practices in which the person took part. So the presentation of Scribner’s life history brings this book into accordance with Scribner’s own theorization. Scribner was engaged in research toward understanding and creating a decent life for all people regardless of geographical position, race, gender, and social class. Her research differs from the more traditional cultural studies looking for differences between people in different cultures. Instead she studied the diversity of human mind as thinking and action in practice. It was variations of conditions for practice that was her concern, to come to understand the conditions for human functioning and development, not the differences between people from different cultures in itself. Scribner graduated as a labor economist from Smith College (a women’s college at that time), and was employed by the United Electrical, Radio, and Machine Workers of America. Already in her union work Scribner started to study mind and action in labor activity. Through investigation of work conditions she argued and fought for change in these, both on the level of actual sites and in general. Her aim was to widen public understanding of the relation between working conditions and health in general and
Backward Interpolation Architecture for Algebraic Soft-Decision Reed–Solomon Decoding

Recently developed algebraic soft-decision (ASD) decoding of Reed-Solomon (RS) codes have attracted much interest due to the fact that they can achieve significant coding gain with polynomial complexity. One major step of ASD decoding is the interpolation. Available interpolation algorithms can only add interpolation points or increase interpolation multiplicities. However, backward interpolation, which eliminates interpolation points or reduces interpolation multiplicities, is indispensable to enable the reusing of interpolation results in the following two scenarios: 1) interpolation needs to be carried out on multiple test vectors, which share common entries and 2) iterative ASD decoding where interpolation points have decreasing multiplicities. Examples for these cases are the low-complexity chase (LCC) decoding and bit-level generalized minimum distance (BGMD) decoding. With lower complexity, these algorithms can achieve similar or higher coding gain than other practical ASD algorithms. In this paper, we propose novel backward interpolation schemes and corresponding efficient implementation architectures for LCC and BGMD decoding through constructing equivalent GrOumlbner bases. The proposed architectures share computational units with forward interpolation architectures. Hence, the area overhead for incorporating the backward interpolation is very small. Substantial area saving or speedup can be achieved by using the backward interpolation. When the proposed architecture is applied to the LCC decoding of a (255, 239) RS code with eta = 3, the area is reduced to 39% of those required by prior architectures. In terms of speed/area ratio, the proposed architecture is 48% more efficient than the best available architecture. For the BGMD decoding of the same code, the proposed architecture can achieve around 20% higher efficiency.
A Monolithic CMOS-MEMS Oscillator Based on an Ultra-Low-Power Ovenized Micromechanical Resonator

A fully monolithic complimentary metal-oxide- semiconductor-microelectormechanical systems (CMOS-MEMS) oscillator comprised of an ovenized double-ended tuning fork resonator to enable ultra-low heater power operation of only 0.47 mW over entire temperature span (-40 °C to 85 °C) and a low noise sustaining circuit to achieve low phase noise has been demonstrated in a Taiwan Semiconductor Manufacturing Company (TSMC) 0.35-μm CMOS process. The combination of low thermal conductivity material and high thermal isolation design is the key to attaining ultra-low-power heater operation in a sub-mW level. Passive temperature compensation scheme is also conducted in the proposed CMOS-MEMS resonator by an oxide-metal composite structure, showing a low temperature coefficient of frequency (TC f ) of only +5.1 ppm/°C, which is suited for the use in ovenized oscillator systems. By implementing a constant-resistance temperature control scheme, the frequency drift of the resonator smaller than 120 ppm from -40 °C to 85 °C is demonstrated in this paper, indicating an equivalent TC f smaller than 1 ppm/°C, a record-low value against its CMOSMEMS counterparts. The CMOS-MEMS oscillator operating at 1.2 MHz demonstrates a phase noise of -112 dBc/Hz at 1-kHz offset and -120 dBc/Hz at 1-MHz offset while drawing less than 1.3 mW. The entire power consumption of the ovenized oscillator system is confirmed to be less than 1.8 mW (oscillator + micro-oven), verifying the great potential of low power oven-controlled MEMS oscillators realized in CMOS-MEMS technology.
Multiple Marginality

Achieving diversity in the workplace has become the antidote for what ails many organizations. Specifically for public organizations, although many genuinely pursue diversity to achieve public good, some use diversity for more questionable means. An exploratory study on local governments revealed that women and minorities, relative to White men, are disproportionately assigned to manage diversity programs. Using the research on groups, a theory of multiple marginality was developed to explicate the rationale(s) for these programs’ overrepresentation of women and minorities that further marginalizes these already marginalized groups. The adverse effects, the policy implications, and future research are discussed.
Fighting Perebor: New and Improved Algorithms for Formula and QBF Satisfiability

We investigate the possibility of finding satisfying assignments to Boolean formulae and testing validity of quantified Boolean formulae (QBF) asymptotically faster than a brute force search. Our first main result is a simple deterministic algorithm running in time $2^{n - \Omega(n)}$ for satisfiability of formulae of linear size in $n$, where $n$ is the number of variables in the formula. This algorithm extends to exactly counting the number of satisfying assignments, within the same time bound. Our second main result is a deterministic algorithm running in time $2^{n - \Omega(n/\log(n))}$ for solving QBFs in which the number of occurrences of any variable is bounded by a constant. For instances which are ``structured'', in a certain precise sense, the algorithm can be modified to run in time $2^{n - \Omega(n)}$. To the best of our knowledge, no non-trivial algorithms were known for these problems before. As a byproduct of the technique used to establish our first main result, we show that every function computable by linear-size formulae can be represented by decision trees of size $2^{n - \Omega(n)}$. As a consequence, we get strong super linear {\it average-case} formula size lower bounds for the Parity function.
Performance comparison of cooperative downlink transmission schemes in IEEE 802.11ac: Interference alignment vs. MU-MIMO with TDMA

Recently, demand for high data rate of wireless service is increased due to full high definition (HD) video transmission and cloud services and so on. To enhance the capacity, many APs are installed in various places. Because of multiple APs are deployed in unplanned situation, interference between basic service set (BSS) is increased. To reduce the overlapped BSS (OBSS) interference of IEEE 802.11ac interfering broadcasting network, we suggest two cooperative transmission schemes which are interference alignment (IA) and multi-user multi-input and multi-output (MU-MIMO) with time division multiple access (TDMA). We can simultaneously transmit the data in the same time and frequency with IA, however, the required overhead of transmission for IA is considerably high. However, MU-MIMO with TDMA scheme needs lower overhead than IA because only channel state information (CSI) feedback of a desired link from AP to STA and AP Poll transmission which decides the timely transmission order for MU-MIMO with TDMA. Even though there are a few feedback quantity for MU-MIMO with TDMA, the average throughput will be reduced because the data should be transmitted by dividing the time. Therefore, we have observed the average throughput between IA and MU-MIMO with TDMA in IEEE 802.11ac interfering downlink network. And we also compare the performance between two cooperative downlink transmission schemes.
Toward Values Education in Tourism: The Challenge of Measuring the Values

Values are implicit in our education systems and practices—they are reflected in the choices that we make about what to teach, how to teach, and who to teach it to. Values education is about making values explicit and about focusing education on a particular set of values. This article reports on part of such an initiative within tourism education in universities and colleges, the Tourism Education Futures Initiative (TEFI), the development of tools to measure values. In particular it reports on an exercise conducted with university students to develop a pool of items for the development of a TEFI Values Inventory.
Recycling of the Yeast a-Factor Receptor Linyi

The yeast a -factor receptor (Ste3p) is subject to two mechanistically distinct modes of endocytosis: a constitutive, ligand-independent pathway and a liganddependent uptake pathway. Whereas the constitutive pathway leads to degradation of the receptor in the vacuole, the present work finds that receptor internalized via the ligand-dependent pathway recycles. With the a -factor ligand continuously present in the culture medium, trafficking of the receptor achieves an equilibrium in which continuing uptake to endosomal compartments is balanced by its recycling return to the plasma membrane. Withdrawal of ligand from the medium leads to a net return of the internalized receptor back to the plasma membrane. Although recycling is demonstrated for receptors that lack the signal for constitutive endocytosis, evidence is provided indicating a participation of recycling in wild-type Ste3p trafficking as well: a -factor treatment both slows wild-type receptor turnover and results in receptor redistribution to intracellular endosomal compartments. Apparently, a -factor acts as a switch, diverting receptor from vacuole-directed endocytosis and degradation, to recycling. A model is presented for how the two Ste3p endocytic modes may collaborate to generate the polarized receptor distribution characteristic of mating cells.
