Low-power MicroVrms noise neural spike detector for implantable interface microsystem device

In this paper, an ultra-low-power and low-noise spike detector is proposed for massive integration in the implantable multichannel brain neural recording device. The detector circuit with nonlinear energy operator (NEO) algorithms achieves the spike detecting from action potential including complex noise. The spike detector circuit consists of a differentiator with a fully-differential structure and a multiplier based on CMOS translinear using sub-threshold technique. The differentiator has the steepness of a transmission function with frequency +20 dB/dec, frequency response from 10 Hz to 10.5 kHz. The linear range of multiplier is from −0.9 V to 0.9 V at V_DD = ±1.65 V. The spike detector is implemented in 0.35 μm technology with fully-CMOS process. One detector die size is 0.0187 mm² and its total current consumption of 825 nA. As is demonstrated by measured results, the proposed circuit has detected the instantaneous energy of the input real spike signals well, which the noise of small than 218 μV_rms over a nominal bandwidth of 500–10.5 kHz.     

Global self-esteem in relation to structural models of personality and affectivity.

Three studies examined global self-esteem in relation to structural models of personality and affectivity. In every study, self-esteem was strongly negatively correlated with Neuroticism/Negative Affectivity and moderately to strongly related to Extraversion/Positive Affectivity. Additional findings, however, revealed that self-esteem is better viewed at the lower order level. For instance, global self-esteem correlated -.79 with the Depression facet of the Revised NEO Personality Inventory (P. T. Costa, Jr., & R. R. McCrae, 1992) in Study 3. Moreover, confirmatory factor analyses produced very strong correlations between self-esteem and depression in both Study 2 (r = -.82) and Study 3 (r = -.86). Taken together, the data suggest that global self-esteem measures define one end of a bipolar continuum, with trait indicators of depression defining the other.

Introduction to the special section on assessing personality characteristics in clinical settings.

Personality assessment in clinical settings is an important and often difficult undertaking, requiring the collection and integration of extensive personal history, personality, and symptomatic information. Clinicians are frequently faced with making important decisions on the basis of limited information. New conceptualizations and new techniques for describing personality and behavior are welcome additions to the clinician's assessment battery, and if productive, are eagerly sought to enhance clinical assessment. The goals of this special section are threefold: First, in their contribution, Costa and McCrae (1991a) explore the possibility that the NEO can provide new and different information that practitioners would find valuable in depicting or describing clients in the clinical assessment context. Second, the article by Ben-Porath and Waller (1991a) provides insight into the criteria by which "normal-range" assessment instruments might be evaluated. They examine the NEO on the basis of these criteria. Third, we hope that the Costa/McCrae (1992a, 1992b) and Ben-Porath/Waller (1992a, 1992b) discussion will serve as a productive interchange on the potential utility of this assessment approach for clinical assessment.

A multimethod assessment of juvenile psychopathy: Comparing the predictive utility of the PCL:YV, YPI, and NEO PRI.

The current study compares 3 distinct approaches for measuring juvenile psychopathy and their utility for predicting short- and long-term recidivism among a sample of 1,170 serious male juvenile offenders. The assessment approaches compared a clinical interview method (the Psychopathy Checklist: Youth Version [PCL:YV]; Forth, Kosson, & Hare, 2003), a new self-report measure (the Youth Psychopathic Traits Inventory; Andershed, Kerr, Stattin, & Levander, 2002), and a personality-based approach (the NEO Psychopathy Resemblance Index; Lynam & Widiger, 2007). Results indicate a modest overlap between the 3 measures (rs = .26–.36); however, youths were often identified as psychopathic by 1 measure but not by others. Measures were weakly correlated with reoffending during subsequent 6- and 12-month periods. Findings suggest that although such scores may be useful indicators of the need for heightened monitoring in the short term, care should be taken when making predictions about long-term recidivism among adolescents. Moreover, the lack of long-term predictive power for the PCL:YV and the inconsistent psychopathy designations obtained with different measures raise serious questions about the use of such measures as the basis for legal or clinical treatment decisions.

基于图形数据库的DBLP数据存储

DBLP数据不但数据规模大,而且数据之间存在多种类型的关联关系,包括合作关系、写作关系、引用关系等。采用关系数据存储时不但存在大量的数据冗余,并且难于动态更新,为解决复杂关联关系的高效存储与动态更新问题,提出一种基于图形数据库的DBLP数据表示与存储方法,论文、作者、书籍等实体以节点存储,而实体间的各种关系以多类型的边存储。实验表明该方法能够有效支持关联关系的动态增删、多阶查询、深度遍历、广度遍历等操作,有效解决了复杂关联关系的数据存储问题。     

Is the genetic structure of human personality universal? A cross-cultural twin study from North America, Europe, and Asia.

This study examined whether universality of the 5-factor model (FFM) of personality operationalized by the Revised NEO Personality Inventory is due to genetic influences that are invariant across diverse nations. Factor analyses were conducted on matrices of phenotypic, genetic, and environmental correlations estimated in a sample of 1,209 monozygotic and 701 dizygotic twin pairs from Canada, Germany, and Japan. Five genetic and environmental factors were extracted for each sample. High congruence coefficients were observed when phenotypic, genetic, and environmental factors were compared in each sample as well as when each factor was compared across samples. These results suggest that the FFM has a solid biological basis and may represent a common heritage of the human species. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Are cross-cultural comparisons of personality profiles meaningful? Differential item and facet functioning in the Revised NEO Personality Inventory.

Measurement invariance is a prerequisite for confident cross-cultural comparisons of personality profiles. Multigroup confirmatory factor analysis was used to detect differential item functioning (DIF) in factor loadings and intercepts for the Revised NEO Personality Inventory (P. T. Costa, Jr., & R. R. McCrae, 1992) in comparisons of college students in the United States (N = 261), Philippines (N = 268), and Mexico (N = 775). About 40%–50% of the items exhibited some form of DIF and item-level noninvariance often carried forward to the facet level at which scores are compared. After excluding DIF items, some facet scales were too short or unreliable for cross-cultural comparisons, and for some other facets, cultural mean differences were reduced or eliminated. The results indicate that considerable caution is warranted in cross-cultural comparisons of personality profiles. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

NEO Bankside

Beyond the City's walls, Southwark was for hundreds of years one of the capital's liveliest boroughs: London's industrial backyard and entertainment district. It was the site of Shakespeare's Globe Theatre and the Vauxhall Pleasure Gardens as well as several prisons, such as the Marshalsea. However, it fell into decline in the late 20th century as print works and the London docks closed. Matthew Gandy describes a new development in Southwark, adjacent to Tate Modern, which marks its reinvention as a luxurious enclave for the internationally rich.
