Temporal-Spatial Neural Activation Patterns Linked to Perceptual Encoding of Emotional Salience

It is well known that we continuously filter incoming sensory information, selectively allocating attention to what is important while suppressing distracting or irrelevant information. Yet questions remain about spatiotemporal patterns of neural processes underlying attentional biases toward emotionally significant aspects of the world. One index of affectively biased attention is an emotional variant of an attentional blink (AB) paradigm, which reveals enhanced perceptual encoding for emotionally salient over neutral stimuli under conditions of limited executive attention. The present study took advantage of the high spatial and temporal resolution of magnetoencephalography (MEG) to investigate neural activation related to emotional and neutral targets in an AB task. MEG data were collected while participants performed a rapid stimulus visual presentation task in which two target stimuli were embedded in a stream of distractor words. The first target (T1) was a number and the second (T2) either an emotionally salient or neutral word. Behavioural results replicated previous findings of greater accuracy for emotionally salient than neutral T2 words. MEG source analyses showed that activation in orbitofrontal cortex, characterized by greater power in the theta and alpha bands, and dorsolateral prefrontal activation were associated with successful perceptual encoding of emotionally salient relative to neutral words. These effects were observed between 250 and 550 ms, latencies associated with discrimination of perceived from unperceived stimuli. These data suggest that important nodes of both emotional salience and frontoparietal executive systems are associated with the emotional modulation of the attentional blink.
Influence of Polyelectrolyte Multilayer Properties on Bacterial Adhesion Capacity

Bacterial adhesion can be controlled by different material surface properties, such as surface charge, on which we concentrate in our study. We use a silica surface on which poly(allylamine hydrochloride)/sodium poly(4-styrenesulfonate) (PAH/PSS) polyelectrolyte multilayers were formed. The corresponding surface roughness and hydrophobicity were determined by atomic force microscopy and tensiometry. The surface charge was examined by the zeta potential measurements of silica particles covered with polyelectrolyte multilayers, whereby ionic strength and polyelectrolyte concentrations significantly influenced the build-up process. For adhesion experiments, we used the bacterium Pseudomonas aeruginosa. The extent of adhered bacteria on the surface was determined by scanning electron microscopy. The results showed that the extent of adhered bacteria mostly depends on the type of terminating polyelectrolyte layer, since relatively low differences in surface roughness and hydrophobicity were obtained. In the case of polyelectrolyte multilayers terminating with a positively charged layer, bacterial adhesion was more pronounced than in the case when the polyelectrolyte layer was negatively charged.
Female-Specific Intergenerational Transmission Patterns of the Human Corticolimbic Circuitry

Parents have large genetic and environmental influences on offspring's cognition, behavior, and brain. These intergenerational effects are observed in mood disorders, with particularly robust association in depression between mothers and daughters. No studies have thus far examined the neural bases of these intergenerational effects in humans. Corticolimbic circuitry is known to be highly relevant in a wide range of processes, including mood regulation and depression. These findings suggest that corticolimbic circuitry may also show matrilineal transmission patterns. Therefore, we examined human parent–offspring association in this neurocircuitry and investigated the degree of association in gray matter volume between parent and offspring. We used voxelwise correlation analysis in a total of 35 healthy families, consisting of parents and their biological offspring. We found positive associations of regional gray matter volume in the corticolimbic circuit, including the amygdala, hippocampus, anterior cingulate cortex, and ventromedial prefrontal cortex between biological mothers and daughters. This association was significantly greater than mother–son, father–daughter, and father–son associations. The current study suggests that the corticolimbic circuitry, which has been implicated in mood regulation, shows a matrilineal-specific transmission patterns. Our preliminary findings are consistent with what has been found behaviorally in depression and may have clinical implications for disorders known to have dysfunction in mood regulation such as depression. Studies such as ours will likely bridge animal work examining gene expression in the brains and clinical symptom-based observations and provide promising ways to investigate intergenerational transmission patterns in the human brain. SIGNIFICANCE STATEMENT Parents have large genetic and environmental influences on the offspring, known as intergenerational effects. Specifically, depression has been shown to exhibit strong matrilineal transmission patterns. Although intergenerational transmission patterns in the human brain are virtually unknown, this would suggest that the corticolimbic circuitry relevant to a wide range of processes including mood regulation may also show matrilineal transmission patterns. Therefore, we examined the degree of association in corticolimbic gray matter volume (GMV) between parent and offspring in 35 healthy families. We found that positive correlations in maternal corticolimbic GMV with daughters were significantly greater than other parent–offspring dyads. Our findings provide new insight into the potential neuroanatomical basis of circuit-based female-specific intergenerational transmission patterns in depression.
Depletion of calcium from the sarcoplasmic reticulum during calcium release in frog skeletal muscle.

1. Free intracellular calcium transients (delta[Ca2+] were monitored in cut segments of frog skeletal muscle fibres voltage clamped in a double Vaseline‐gap chamber and stretched to sarcomere lengths that eliminated fibre movement. The measured calcium transients were used to calculate the rate of calcium release from the sarcoplasmic reticulum (s.r.) as previously described (Melzer, Rios & Schneider, 1984, 1987). 2. Conditioning pulses were found to suppress the rate of calcium release in test pulses applied after the conditioning pulse. Various combinations of conditioning and test pulses were used to investigate the basis of the suppression of calcium release by the conditioning pulse. 3. Using a constant test pulse applied at varying intervals after a constant conditioning pulse, recovery from suppression of release was found to occur in two phases. During the fast phase of recovery, which was completed within about 1 s, the rate of calcium release was smaller and had a different wave form than the unconditioned control release. The early peak in release that is characteristic of the control release wave form was absent or depressed. During the slow phase of recovery, which required about 1 min for completion, the release wave form was the same as control but was simply scaled down compared to the control. 4. Conditioning pulses also slowed the rate of decay of delta[Ca2+] after a constant test pulse, probably due to an increased occupancy by calcium of slowly equilibrating myoplasmic sites that bind some of the calcium released by the conditioning pulse. Since calcium binding to these sites contributes to the decay of delta[Ca2+], their increased occupancy would slow the decay of delta[Ca2+] following the test pulse. This effect was used to estimate the calcium occupancy of the slowly equilibrating sites. 5. Comparison of the time course of the slow recovery from suppression of release following a constant conditioning pulse with the time course of the loss of calcium from the slowly equilibrating myoplasmic calcium binding sites indicated that the two processes occurred in parallel. 6. Using a set 1 s recovery period and a constant test pulse but varying the amplitude and/or duration of the conditioning pulse, the degree of slowly recovering suppression of release was found to be directly related to the amount of calcium remaining outside of the s.r. at the start of the test pulse. 7. Points 3, 5 and 6 above indicate that the slow recovery from suppression of release may be due to slow recovery from depletion of calcium from the s.r. (ABSTRACT TRUNCATED AT 400 WORDS)
Phosphoenolpyruvate mutase catalysis of phosphoryl transfer in phosphoenolpyruvate: kinetics and mechanism of phosphorus-carbon bond formation.

Phosphoenolpyruvate phosphomutase (PEP mutase) from Tetrahymena pyriformis catalyzes the rearrangement of phosphoenolpyruvate (PEP) to phosphonopyruvate (P-pyr). A spectrophotometric P-pyr assay consisting of the coupled actions of P-pyr decarboxylase, phosphonoacetaldehyde hydrolase, and alcohol dehydrogenase was devised to monitor mutase catalysis. The reaction constants determined for PEP mutase catalyzed conversion of PEP to P-pyr at pH 7.5 and 25 degrees C in the presence of Mg(II) are kcat = 5 s(-1), Km = 0.77 +/- 0.05 mM, and Keq = (2-9) x 10(-4). In the PEP forming direction, kcat = 100 s(-1) and Km = 3.5 +/- 0.1 microM. Retention of stereochemistry at phosphorus and strong inhibition displayed by the pyruvyl enolate analog, oxalate, have been cited as two lines of evidence that PEP mutase catalysis proceeds via a phosphoenzyme-pyruvyl enolate intermediate [Seidel, H. M. , & Knowles, J. R. (1994) Biochemistry 33, 5641-5646]. In this study, single turnover reactions of oxalyl phosphate with the PEP mutase were carried out to test the formation of the phosphoenzyme intermediate. If formed. the phosphoenzyme-oxalate complex should be sufficiently stable to isolate. Reaction of the mutase with [32P]oxalyl phosphate in the presence of Mg(II)/Mn(II) cofactor failed to produce a detectable level of the [32P]phosphoenzyme-oxalate complex. In contrast, the same reaction carried out with pyruvate phosphate dikinase (PPDK), an enzyme known to catalyze the phosphorylation of its active site histidine with PEP, occurred at a rate of 4 x 10(-4) s(-1) (15% E-P formed) in the presence Mg(II) and at a rate of 3 x 10(-3) s(-1) (60% E-P formed) in the presence of Mn(II). Both oxalyl phosphate (Ki = 180 +/- 10 microM) and oxalate (Ki = 32 +/- 1O microM) were competitive inhibitors of PEP mutase catalysis, but neither displayed slow, tight binding inhibition. These results do not support the intermediacy of a phosphoenzyme-pyruvyl enolate complex in PEP mutase catalysis.
Interactive volume rendering in virtual environments

This dissertation is about the interactive visualization of volume data in virtual environments. Only data on regular grids will be discussed. Research was conducted on three major topics: visualization algorithms, user interfaces, and parallelization of the visualization algorithms. Because the shear-warp algorithm is a very fast CPU-based volume rendering algorithm, it was investigated how it could be adapted to the characteristics of virtual environments. This required the support of perspective projection, as well as specific developments for interactive work, for instance a variable frame rate or the application of clipping planes. Another issue was the improvement of image quality by the utilization of pre-integration for the compositing. Concerning the user interface, a transfer function editor was created, which was tailored to the conditions of virtual environments. It should be usable as intuitively as possible, even with imprecise input devices or low display resolutions. Further research was done in the field of direct interaction, for instance a detail probe was developed which is useful to look inside of a dataset. In order to run the user interface on a variety of output devices, a device independent menu and widget system was developed. The shear-warp algorithm was accelerated by a parallelization which is based on MPI. For the actual volume rendering, a remote parallel computer can be employed, which needs to be linked to the display computer via a network connection. Because the image transfer turned out to be the bottleneck of this solution, it is compressed before being transferred. Furthermore, it will be described how all the above developments were combined to a volume rendering system, and how they were integrated into an existing visualization toolkit.
An improved routing protocol based on Gauss-Markov model in Ad Hoc networks utilizing prediction of link quality

Ample research has been conducted in routing protocols for Mobile Ad Hoc Networks while traditional protocols cannot satisfy the demand of highly-dynamic environment. Though nodes in highly-dynamic environment often have supersonic velocity, they mainly perform their task with the same mission and their velocity and direction are basically approximate. Hence, the feature makes it possible to forecast links' quality. In this paper, Gauss-Markov mobility model (GM) was introduced in order to reduce the influence of random movement on simulation performance; meanwhile we have improved the routing protocol based on DSR by utilizing the idea of link's lifetime. Although the improved protocol may increase the number of hops in data transmission, it makes the network more stable. Compared to the original DSR protocol based `minimum hops', simulation results operated in Qualnet present us the superior performances of the improved protocol, especially in Packet Delivery Ratio, Received Throughput, Average End-to-end Delay and Average Jitter.
The Impact of Behavioral Style and Status Characteristics on Social Influence: A Test of Two Competing Theories

Two theories of social influence during interaction are compared. A cognitive theory (Status Characteristics and Expectation States) contends that dominance and influence in small groups are caused by cognitions about performance' expectations activated by the status characteristics of members. An alternative argument (Two-Process Theory) contends that it is the observable demeanor of group members that is the cause of dominance and influence. A 3 x 3 x 2 factorial design was used to test the separate effects of status knowledge and demeanor on influence. Each of 324 subjects viewed one of 18 different videotapes of a mock jury deliberation in a personal injury case. Three levels of demeanor (deference-demanding, neutral, and deferential) and three levels of occupational status were manipulated. Influence was measured in terms of changes in amount of the damage award subjects chose. Results showed that social influence was dependent solely upon the demeanor variable. Analysis of a post-decision questionnaire showed that subjects distorted perceptions of the performances of high status participants even though they were influenced through demeanor variation.
Optimal Design of Uniform Rectangular Antenna Arrays for Strong Line-of-Sight MIMO Channels

We investigate the optimal design of uniform rectangular arrays (URAs) employed in multiple-input multiple-output communications, where a strong line-of-sight (LOS) component is present. A general geometrical model is introduced to model the LOS component, which allows for any orientation of the transmit and receive arrays, and incorporates the uniform linear array as a special case of the URA. A spherical wave propagation model is used. Based on this model, we derive the optimal array design equations with respect to mutual information, resulting in orthogonal LOS subchannels. The equations reveal that it is the distance between the antennas projected onto the plane perpendicular to the transmission direction that is of importance with respect to design. Further, we investigate the influence of nonoptimal design, and derive analytical expressions for the singular values of the LOS matrix as a function of the quality of the array design. To evaluate a more realistic channel, the LOS channel matrix is employed in a Ricean channel model. Performance results show that even with some deviation from the optimal design, we get better performance than in the case of uncorrelated Rayleigh subchannels.
A rare case of apical hypertrophic cardiomyopathy (AHCM)

ABSTRACT Apical hypertrophic cardiomyopathy is a rare form of hypertrophic cardiomyopathy that involves thickening of the distal portion of the left ventricular wall. Most commonly seen in the Japan, with a prevalence rate of about 15% of all HCM patient, its incidence in the USA is approximately 3% of HCM cases. We report a case of a 46-year-old woman with history of hypertension who presented to emergency department with worsening dyspnea and orthopnea with features of left ventricular hypertrophy (LVH) and diffuse large T-wave inversions in the lateral leads on a 12-lead ECG. Further work up revealed severe concentric LVH, with near obliteration of the LV cavity. Ventriculogram showed severe symmetric hypertrophy of the mid to lower septum, extending to the apex of left ventricle with significant pressure gradient of at least 160 mmHg across the apex to mid septal cavity, with no significant gradient across the left ventricular outflow tract. These findings were consistent with apical hypertrophic cardiomyopathy. She was treated with verapamil and metoprolol and has remained asymptomatic over last 2.5 years of follow-up. Although the clinical presentation of AHCM can be variable and nonspecific; however, hallmark findings on ECG and echo can be extremely important in its diagnosis. Abbreviations: AHCM: Apical hypertrophic cardiomyopathy; ECG: Electrocardiogram; LVH: Left ventricular hypertrophy; LVOT: Left ventricular outflow tract
Improving speaker diarization for CHIL lecture meetings

Speaker diarization is often performed before automatic speech recognition (ASR) to label speaker segments. In this paper we present two simple schemes to improve the speaker diarization performance. The first is to iteratively refine GMM speaker models by frame level re-labelingand smoothingof the decision likelihood. The second is to use word level alignment information from the ASR process. We focus on the CHIL lecture meeting data. Our experiments on the NIST RT06 evaluation data show that these simple methods are quite effective in improving our baseline diarization system, with alignment information providing 1% absolute reduction in diarization error rate (DER) and the re-label smoothing providing an additional 3.51% absolute reduction in DER. The overall system generates a DER that is 6.8% relative better than the top performing system from the RT06 evaluation.
Towards a Trusted Mobile RFID Network Framework

Although the mobile RFID system has various applications in Internet of Things(IoT), it has a limited communication range and raises some serious privacy and security problems. To improve the issuers above, we propose a new mobile RFID network framework based on security and privacy protection. In the framework, we design a Reader Network using ad hoc mechanism, that readers with short communication range could extend their communication distance for meeting more application service requirement. Meanwhile, we introduce TPM(Trusted Platform Module) to reader node to ensure the security and privacy of node and give the detailed trusted and privacy mechanisms based on TPM. These mechanisms ensure the node secure and privacy.
Papers are never finished, just abandoned: The role of written teacher comments in the revision process

The debate over the efficacy of written teacher comments has raised a variety of questions for consideration by both researchers and practitioners. Teachers can use written comments, in Vygotsky’s (1978) framework, to scaffold the development of student writing. By reflecting on their own commenting process, a teacher can assess and modify their comments as well as the method by which the comments are delivered. This study examines how four second language (L2) students responded to a series of comments to three papers. The results show that students overwhelmingly followed the strategy training on how to respond to teacher’s comments given during class; however, these changes did not always result in a positive revision. While students believed to have followed the teacher’s suggestions, they did not always pay attention to the paper as a whole, which resulted in problems with coherence or grammar, and even instances of plagiarism. Results indicate that strategy training does not guarantee an outcome of successful revision. This suggests that revision will be more effective for paper development if understood as part of the creative process of writing than mere correction of errors. Based on these results, several proposals are made for modifying the comment process.
Organizational context and employee reactions to psychological contract breach: A multilevel test of competing theories

This study examines how organizational context affects employee reactions to perceived psychological contract breach. Using Conservation of Resources and Social Comparison theories, the authors develop competing hypotheses regarding the potential exacerbating vs. buffering effects of organizational context on the relationships between psychological contract breach and job security satisfaction, job satisfaction, work–family conflict, and burnout. They collected a multi-source, multilevel data set composed of faculty and departmental administrators at a university experiencing repeated budget reductions. It was found that psychological contract breach was related to detrimental job outcomes (i.e., decreased job security satisfaction and job satisfaction, increased work–family conflict, and burnout). However, this relationship was stronger among faculty in departments reporting low rather than high departmental budget cuts, thus supporting Social Comparison theory rather than Conservation of Resources theory. Social comparison matters when it comes to psychological contract breach.
Some problems related to the development of a grammar checker

Developing a grammar checker presents problems to the linguist and to linguistic software that are far from trivial. In this paper we will discuss various kinds of problems that we have encountered during our work with developing a grammar checker for Norwegian (Bokmal). The grammar checker in question, developed in cooperation with Lingsoft OY and to be used in Microsoft Word from the summer 2001, will be applied on text that has been grammatically tagged and disambiguated by the Constraint Grammar method (Karlsson et al 1995, Hagen and Johannessen 1998, and Hagen, Johannessen and Noklestad 2000a, 2000b). The fact that the input text has been multi-tagged and disambiguated before grammar checking has certain advantages, but also presents certain problems, as we shall see.
