Abnormally reduced dorsomedial prefrontal cortical activity and effective connectivity with amygdala in response to negative emotional faces in postpartum depression.

OBJECTIVE Postpartum major depression is a significant public health problem that strikes 15% of new mothers and confers adverse consequences for mothers, children, and families. The neural mechanisms involved in postpartum depression remain unknown, but brain processing of affective stimuli appears to be involved in other affective disorders. The authors examined activity in response to negative emotional faces in the dorsomedial pre-frontal cortex and amygdala, key emotion regulatory neural regions of importance to both mothering and depression. METHOD Postpartum healthy mothers (N=16) and unmedicated depressed mothers (N=14) underwent functional magnetic resonance imaging blood-oxygen-level-dependent acquisition during a block-designed face versus shape matching task. A two-way analysis of variance was performed examining main effects of condition and group and group-by-condition interaction on activity in bilateral dorsomedial prefrontal cortical and amygdala regions of interest. RESULTS Depressed mothers relative to healthy mothers had significantly reduced left dorsomedial prefrontal cortical face-related activity. In depressed mothers, there was also a significant negative correlation between left amygdala activity and postpartum depression severity and a significant positive correlation between right amygdala activity and absence of infant-related hostility. There was reliable top-down connectivity from the left dorsomedial prefrontal cortex to the left amygdala in healthy, but not depressed, mothers. CONCLUSIONS Significantly diminished dorsomedial prefrontal cortex activity and dorsomedial prefrontal cortical-amygdala effective connectivity in response to negative emotional faces may represent an important neural mechanism, or effect, of postpartum depression. Reduced amygdala activity in response to negative emotional faces is associated with greater postpartum depression severity and more impaired maternal attachment processes in postpartum depressed mothers.
External MPC Unit Discussion Paper No . 25 Household external finance and consumption

This paper uses mortgage data to construct a measure of terms on which households access to external finance, and relates it to consumption at both the aggregate and cohort levels. The Household External Finance (HEF) index is based on the spread paid by risky borrowers in the mortgage market. There is evidence that the terms of access to external finance matter more for the consumption of young cohorts in UK data. Results are robust to a wide variety of specifications.
Long term behavior of a hypothetical planet in a highly eccentric orbit

Abstract For a hypothetical planet on a highly eccentric or-bit, we have calculated the osculating orbital pa-rameters and its closest approaches to Earth andMoon over a period of 750 kyr. The approacheswhich are close enough to inﬂuence the climate ofthe Earth form a pattern comparable to that of thepast climatic changes, as recorded in deep sea sedi-ments and polar ice cores. 1 Motivation The information on Earth’s past climate obtainedfrom deep sea sediments and polar ice cores indi-cates that the global temperature oscillated with asmall amplitude around a constant mean value formillions of years until about 3.2 million years ago.Fromthen on the mean temperaturedecreasedstep-wise and the amplitude of the variations increased.For the last one million years Earth’s climate wascharacterized by a distinct 100 kyr periodicity inthe advancing and retreating of the polar ice sheets,known as glacial–interglacial cycles. This Ice Ageperiod ended abruptly 11.5 kyr ago. During the fol-lowing time interval, the Holocene, the global meantemperature quickly recovered to a value compara-ble with that observed 3.2 Myr ago [1, 2]. Wolﬂi etal. [3] proposed that during all this time an objectof planetary size, called Z, existed in a highly ec-centric orbit, and showed that Z could be the causeof these changes of Earth’s climate. Because of thepostulated small perihelion distance, Z was heatedup by solar radiation and tidal forces so that it wassurrounded by a gas cloud. Whenever the Earth
Robust H ∞ Filtering for a Class of Complex Networks with Stochastic Packet Dropouts and Time Delays

The robust H ∞ filtering problem is investigated for a class of complex network systems which has stochastic packet dropouts and time delays, combined with disturbance inputs. The packet dropout phenomenon occurs in a random way and the occurrence probability for each measurement output node is governed by an individual random variable. Besides, the time delay phenomenon is assumed to occur in a nonlinear vector-valued function. We aim to design a filter such that the estimation error converges to zero exponentially in the mean square, while the disturbance rejection attenuation is constrained to a given level by means of the H ∞ performance index. By constructing the proper Lyapunov-Krasovskii functional, we acquire sufficient conditions to guarantee the stability of the state detection observer for the discrete systems, and the observer gain is also derived by solving linear matrix inequalities. Finally, an illustrative example is provided to show the usefulness and effectiveness of the proposed design method.
Signal Denoising Using Simplified SURE-Based Linear Expansion of Thresholds in the Wavelet Domain

The purpose of signal denoising is to reduce the noise level, while preserving the signal features. Various denoising approaches exist, in which wavelet-based pointwise thresholding approaches are extensively adopted in many application fields. For signal denoising based on wavelet thresholding, there are two crucial aspects, namely, the use of a proper thresholding function and the estimate of the noise standard deviation. Both greatly influence the quality of the denoised signal. In this paper, a simple wavelet-based denoising approach is proposed, which uses the modified linear expansion of thresholds based on Stein’ s unbiased risk estimate (SURE) and the noise standard deviation’s estimation depending on the number of vanishing moments of the wavelet transform. Experimental results demonstrate that higher signal-to-noise ratio (SNR) can be obtained by this new approach as compared to other thresholding approaches.
Least-Squares Methods for Blind Source Separation Based on Nonlinear PCA

In standard blind source separation, one tries to extract unknown source signals from their instantaneous linear mixtures by using a minimum of a priori information. We have recently shown that certain nonlinear extensions of principal component type neural algorithms can be successfully applied to this problem. In this paper, we show that a nonlinear PCA criterion can be minimized using least-squares approaches, leading to computationally efficient and fast converging algorithms. Several versions of this approach are developed and studied, some of which can be regarded as neural learning algorithms. A connection to the nonlinear PCA subspace rule is also shown. Experimental results are given, showing that the least-squares methods usually converge clearly faster than stochastic gradient algorithms in blind separation problems.
LATE PLEISTOCENE HUNTER-GATHERERS AT ISHANGO ( EASTERN ZAIRE ) : THE FAUNAL EVIDENCE

A new examination of the faunal remains collected at the prehistoric site of Ishango has shown that three stages can be distinguished. The first one refers to a Late Pleistocene hunter-fisher-gatherer Community adapted to relatively dry and open savanna living conditions. The second stage may relate to a period of volcanic activity and wetter climatic condit ions in the study area, but without evidence of a human occupation at Ishango. The third stage is again characterised by the presence of a human population, adapted to savanna living conditions.
PERSONALITY TRAITS AND EMOTIONAL INTELLIGENCE AS PREDICTORS OF ENTREPRENEURIAL BEHAVIOUR AMONG STUDENTS OF BENUE STATE UNIVERSITY

This study was aimed at exploring whether personality traits and emotional intelligence predict entrepreneurial behaviour among students of Benue State University, Makurdi. An ex-post-facto design was adopted. Three hundred and forty two (342) students participated in the study. Three measuring instruments were also used for data collection. Findings indicate that, personality traits and emotional intelligence significantly predict entrepreneurial behavior. The finding also showed a strong correlation between the three variables. Based on the findings it was therefore recommended that, believing in the importance of innovation, perceiving new business as an opportunity, having self-efficacy, cognitive abilities, social skills, accurately perceiving others, making good first impression, and holding humanistic image of start-ups would each contribute to greater interest in creating a start-up.
BAG3 Directly Interacts with Mutated alphaB-Crystallin to Suppress Its Aggregation and Toxicity

A homozygous disruption or genetic mutation of the bag3 gene causes progressive myofibrillar myopathy in mouse and human skeletal and cardiac muscle disorder while mutations in the small heat shock protein αB-crystallin gene (CRYAB) are reported to be responsible for myofibrillar myopathy. Here, we demonstrate that BAG3 directly binds to wild-type αB-crystallin and the αB-crystallin mutant R120G, via the intermediate domain of BAG3. Peptides that inhibit this interaction in an in vitro binding assay indicate that two conserved Ile-Pro-Val regions of BAG3 are involved in the interaction with αB-crystallin, which is similar to results showing BAG3 binding to HspB8 and HspB6. BAG3 overexpression increased αB-crystallin R120G solubility and inhibited its intracellular aggregation in HEK293 cells. BAG3 suppressed cell death induced by αB-crystallin R120G overexpression in differentiating C2C12 mouse myoblast cells. Our findings indicate a novel function for BAG3 in inhibiting protein aggregation caused by the genetic mutation of CRYAB responsible for human myofibrillar myopathy.
Practice of Epidemiology Planning for the Control of Pandemic Influenza A ( H 1 N 1 ) in Los Angeles County and the United States

Mathematical and computer models can provide guidance to public health officials by projecting the course of an epidemic and evaluating control measures. The authors built upon an existing collaboration between an academic research group and the Los Angeles County, California, Department of Public Health to plan for and respond to the first and subsequent years of pandemic influenza A (H1N1) circulation. The use of models allowed the authors to 1) project the timing and magnitude of the epidemic in Los Angeles County and the continental United States; 2) predict the effect of the influenza mass vaccination campaign that began in October 2009 on the spread of pandemic H1N1 in Los Angeles County and the continental United States; and 3) predict that a third wave of pandemic influenza in the winter or spring of 2010 was unlikely to occur. The close collaboration between modelers and public health officials during pandemic H1N1 spread in the fall of 2009 helped Los Angeles County officials develop a measured and appropriate response to the unfolding pandemic and establish reasonable goals for mitigation of pandemic H1N1.

An intelligent interface for the design of optimal control systems

An interface for giving suggestions about how to modify weighting matrixes which appear in the formulation of optimal control problems with quadratic performance index is described. The suggestions come both from heuristics for choosing the matrix elements, some of them being obtained through simulations for several systems, and also from criteria for improving the system in relation to the specification of some parameters.
Beunruhigende Weiblichkeit. Zum Thema Adoleszenz

Die Adoleszenz ist eine fur die Geschlechtsidentitat ausschlaggebende Lebensphase, in der sich das Selbst differenziert und die sexuelle Identitat sich endgultig konstituiert. Die Autorin entwirft ein zwischen Mutter und Tochter bei der Geburt sich etablierendes, auf unbewusten Projektionen der Mutter basierendes somatopsychisches Beziehungsmodell von Umhullung und – einer ihres Inhalts entleerten – Hohlung. Im Laufe der Adoleszenz, in der Weiblichkeit, Sexualitat und Mutterschaft im weiblichen Korper reprasentiert und vereinbart werden sollen, steht das Madchen vor der schwierigen Aufgabe, ihr Sein als Hohlung aufzugeben und sich mit der Vorstellung eines korperlichen Beinhaltens zu identifizieren. Anhand des klinischen Fallbeispiels einer bulimischen Adoleszentin sowie von Bemerkungen zum anorektischen Krankheitsbild zeigt die Autorin die schwierige Gratwanderung dieser Aneignung von Weiblichkeit, deren Mislingen bis an den Rand des Todes fuhren kann.
Local electric field enhancement during nanofocusing of plasmons by a tapered gap

We demonstrate that during plasmon nanofocusing in a tapered gap (V groove), local electric field experiences much stronger enhancement than the magnetic field. Two distinct asymptotic regimes are found near the tip of the groove: The electric field approaches either zero or infinity when dissipation is above or below a critical level (at a fixed taper angle), or taper angle is smaller or larger than a critical angle (at a fixed level of dissipation). Tapered gaps are shown to be the best option for achieving maximal field enhancement, compared to nanowedges and tapered rods. An optimal taper angle is determined. © 2007 The American Physical Society.
Multi-layer perceptron learning in the domain of attributed graphs

We propose a multi-layer perceptron for learning on data represented in terms of attributed graphs. The approach is based on the idea to associate each simple perceptron with an attributed weight graph and to provide a concept similar to the inner product of vectors in the domain of graphs. This is achieved by the Schur-Hadamard inner product of graphs. To provide a supervised learning mechanism we customize the feed-forward pass, the error-back-propagation algorithm, and the error correcting rule. In first experiments, the proposed algorithm is successfully applied to function the regression and classification tasks. The results show better performance than support vector and nearest neighbor classifiers.
Alternative Donor Transplantation for Acute Myeloid Leukemia

Allogeneic hematopoietic cell transplantation (allo-HCT) is a potentially curative therapy for adult patients with acute myeloid leukemia (AML), but its use for consolidation therapy after first remission with induction chemotherapy used to be limited to younger patients and those with suitable donors. The median age of AML diagnosis is in the late 60s. With the introduction of reduced-intensity conditioning (RIC), many older adults are now eligible to receive allo-HCT, including those who are medically less fit to receive myeloablative conditioning. Furthermore, AML patients commonly have no human leukocyte antigen (HLA)-identical or medically suitable sibling donor available to proceed with allo-HCT. Technical advances in donor matching, suppression of alloreactivity, and supportive care have made it possible to use alternative donors, such as unrelated umbilical cord blood (UCB) and partially HLA-matched related (haploidentical) donors. Outcomes after alternative donor allo-HCT are now approaching the outcomes observed for conventional allo-HCT with matched related and unrelated donors. Thus, with both UCB and haploidentical donors available, lack of donor should rarely be a limiting factor in offering an allo-HCT to adults with AML.
Geometric Transformations of BDD Encoded Image

Binary Decision Diagram (BDD) has been shown to be applicable in image coding. A tech- nique presented in this paper extends the functional- ity of BDD in image coding to cover major geometric transformations of image such as translation, rota- tions, scaling and shearing. By introducing the con- cept of transition branch, nonuniform and uniform translation of image by a given displacement could be obtained using only exclusive-or operation. Based on the translation, we show that image rotation, scaling and shearing could be achieved.
AMPK and Exercise: Glucose Uptake and Insulin Sensitivity

AMPK is an evolutionary conserved sensor of cellular energy status that is activated during exercise. Pharmacological activation of AMPK promotes glucose uptake, fatty acid oxidation, mitochondrial biogenesis, and insulin sensitivity; processes that are reduced in obesity and contribute to the development of insulin resistance. AMPK deficient mouse models have been used to provide direct genetic evidence either supporting or refuting a role for AMPK in regulating these processes. Exercise promotes glucose uptake by an insulin dependent mechanism involving AMPK. Exercise is important for improving insulin sensitivity; however, it is not known if AMPK is required for these improvements. Understanding how these metabolic processes are regulated is important for the development of new strategies that target obesity-induced insulin resistance. This review will discuss the involvement of AMPK in regulating skeletal muscle metabolism (glucose uptake, glycogen synthesis, and insulin sensitivity).
Reliability, Validity, and Dimensions of SEM-based Sport Tourism Risk Perception Scale

This study utilizes available legal literature, questionnaire surveys, mathematical statistics, and other research methods to establish a risk perception analysis based on prior studies by Rose (1977), Joeoby and Kaplan (1972), Peter and Tarpey (1975), Stone and Gronhuang (1993), and other foreign scholars. Financial risk, information risk, social cognitive risk, liability risk, intellectual risk, functional performance risk, psychological risk, and 31 items of the sports tourism risk perception are employed to form an inspection primer and high-order sports tourism risk perception structural equation model (SEM).
Nonorthogonal Joint Diagonalization/Zero Diagonalization for Source Separation Based on Time-Frequency Distributions

This paper deals with the blind separation of instantaneous mixtures of source signals using time-frequency distributions (TFDs). We propose iterative algorithms to perform the nonorthogonal zero diagonalization and/or joint diagonalization of given sets of matrices. As an application, we show that the source separation can be realized by applying one of these algorithms to a set of spatial quadratic TFD matrices corresponding only to the so-called cross-source terms and/or to the so-called autosource terms. The determination of the above matrices to be jointly decomposed requires first an automatic selection procedure of useful time-frequency points. Regarding this last point, we also propose a new selection procedure and a modification of an existing one and provide a comparison with other existing ones. The nonorthogonal joint diagonalization and/or zero diagonalization algorithm's main advantage is to not require (in the blind source separation context) a prewhitening stage, which allows them to work even with a class of correlated signals and provides generally improved separation performance. Finally, an analytical example and computer simulations are provided in order to illustrate the effectiveness of the proposed approach and to compare it with classical ones
Personality and the nature of collaboration in pair programming

The benefits of synergistic collaboration are at the heart of arguments in favor of pair programming. However, empirical studies usually investigate direct effects of various factors on pair programming performance without looking into the details of collaboration. This paper reports from an empirical study that (1) investigated the nature of pair programming collaboration, and (2) subsequently investigated postulated effects of personality on pair programming collaboration. Audio recordings of 44 professional programmer pairs were categorized according to a taxonomy of collaboration. We then measured postulated relationships between the collaboration categories and the personality of the individuals in the pairs. We found evidence that personality generally affects the type of collaboration that occurs in pairs, and that different levels of a given personality trait between two pair members increases the amount of communication-intensive collaboration exhibited by a pair.
QoS and Failover Routing in Tethernet

Tethering is a low-cost, short-distance, wireless technology which employs the frequency hopping technique in the globally available ISM band to avoid interference. In the tethering, a network consists of one to five masters and up to seven alive slaves, and handful of tethernet can couple with bridges to form a scatternet. The communication performance in a tethernet is depended on several factors, such as the numbers of tethernet and bridges, the role (master or slave) of the bridge, etc. After the entire slave has to halt for master's polling for packet transmission, the master is enhancing the bottleneck or hindrance device for communicating in a tethernet. If routes are established and then maintained in a scatternet all the time, the energy consumption in the scatternet is higher. On the other hand, if an on-demand routing is employed in a scatternet, the energy depletion can be compressed and the route flexibility can be improved. In this thesis, I will propose failover routing that will prevent the stoppage of transmission if the transmitting node about to fail. It will pass its control to another node and allow it to transmit instead of it.
Affricated dental plosives in Russian: phonological status and perceptual cues as a trigger of sound changes

Standard Modern Russian has phonological contrast between palatalized and velarized consonants. One of the most prominent changes attributed recently to this part of its phonetic system is the dramatic affrication of palatalized dental stops which are now pronounced in most phonetic contexts as affricates [t ͡ sj], [d͡zj]. The paper proposes the hypothesis that a fast spread of palatalized dental stops’ affrication in Standard Modern Russian is triggered by the need to more effectively distinguish palatalized plosives in situations that do not provide the primary acoustic cue (formant transition of adjacent vowel) for their differentiation to the listener. Palatalized dental plosives still should be treated phonologically as stops since in the context of homorganic nasal or stop they are not affricated (and often unreleased), while the fricative part of dental affricates in the same position still preserved in pronunciation of all the subjects studied.
