Towards an Exemplar Model of Face Processing: The Effects of Race and Distinctiveness

Valentine (1991a, 1991b) described a theoretical framework for face recognition in which faces are encoded as locations in a multidimensional space. It was argued that this approach could provide a unified account of the effects of distinctiveness, inversion, and race on face recognition. In this paper we evaluate the ability of this theoretical framework to account for the effects of distinctiveness and race in four experiments in which white British and Japanese faces served as stimuli and both white British and Japanese students acted as subjects. In a recognition memory experiment the expected “own-race bias” was observed as a Race of Subject × Race of Face interaction. Distinctive faces were recognized more accurately than typical faces, but the effect of distinctiveness did not interact with the race of face or the race of subject. Typical faces were classified faster than distinctive faces in a task in which intact faces had to be distinguished from jumbled faces, as found in earlier work, and the effect of distinctiveness did not interact with the race of face or race of subject. In contrast, a task in which subjects classified faces according to their race did show a greater effect of distinctiveness for own-race faces. The results are discussed in relation to the two specific models within the multidimensional space framework identified by Valentine (1991a): a purely exemplar-based model and a norm-based coding model. It is argued that these results are more easily accommodated in terms of a purely exemplar-based model. Some conceptual problems in applying the norm-based coding model to the effect of race are discussed.
Image Smoothing via Truncated Total Variation

We present a new regularizer for image smoothing which is particularly effective for diminishing insignificant details, while preserving salient edges. The proposed regularizer relates in spirit to total variation which penalizes all the gradients, while our method just penalizes part of the gradients and leaves the significant edges unchanged. Though the proposed regularizer is a piecewise function, which is hard to optimize, we can unify it to a mathematically sound penalty. The unified penalty term is easy to optimize using recent fast solvers and hard thresholding operation. We show some potential applications of the proposed regularizer, including texture removal and compression artifact restoration. The results show the efficiency of the proposed regularizer.
Coexistence of cholinergic, catecholaminergic, serotonergic, and glutamatergic neurotransmitter markers in mouse clonal hybrid neurons derived from the septal region

Two clonal immortalized neurons designated SN6.1b and SN6.2a were isolated by limiting dilution from a mouse embryonic septal cholinergic neuronal hybrid cell line SN6 (Hammond et al., 1986). In the serum‐containing medium without extra differentiating agents, one‐third of SN6.1b cells stably exhibited a morphology of differentiated neurons with extensive elaborate neurites, while a majority of SN6.2a cells, along with the parent cell line SN6, were round in shape with poorly branched short processes. Neurochemical studies showed that both clones synthesized choline acetyltransferase (ChAT), dopamine, norepinephrine, serotonin, and glutamate. Immunocytochemically, they expressed a number of neuronal antigens, such as 200‐kDa neurofilament protein, neuron‐specific enolase, microtubule‐associated protein 2, tau protein, tubulin, neural cell adhesion molecule, Thy‐1.2, saxitoxin‐binding sodium channel protein, ChAT, tyrosine hydroxylase, serotonin, and glutamate. The coexistence of cholinergic, catecholaminergic, serotonergic, and glutamatergic neurotransmitter markers in the clonal hybrid septal neurons that express a variety of immunocytochemical properties of differentiated neurons suggests that embryonic septal cholinergic neurons are potentially multiphenotypic with respect to neurotransmitter synthesis. © 1992 Wiley‐Liss, Inc.
Genome-Wide Characterization of cis-Acting DNA Targets Reveals the Transcriptional Regulatory Framework of Opaque2 in Maize[OPEN]

The identification of Opaque2 DNA binding targets clarified its direct target genes and revealed its broad transcriptional regulation during endosperm development. Opaque2 (O2) is a transcription factor that plays important roles during maize endosperm development. Mutation of the O2 gene improves the nutritional value of maize seeds but also confers pleiotropic effects that result in reduced agronomic quality. To reveal the transcriptional regulatory framework of O2, we studied the transcriptome of o2 mutants using RNA sequencing (RNA-Seq) and determined O2 DNA binding targets using chromatin immunoprecipitation coupled to high-throughput sequencing (ChIP-Seq). The RNA-Seq analysis revealed 1605 differentially expressed genes (DEGs) and 383 differentially expressed long, noncoding RNAs. The DEGs cover a wide range of functions related to nutrient reservoir activity, nitrogen metabolism, stress resistance, etc. ChIP-Seq analysis detected 1686 O2 DNA binding sites distributed over 1143 genes. Overlay of the RNA-Seq and ChIP-Seq results revealed 35 O2-modulated target genes. We identified four O2 binding motifs; among them, TGACGTGG appears to be the most conserved and strongest. We confirmed that, except for the 16- and 18-kD zeins, O2 directly regulates expression of all other zeins. O2 directly regulates two transcription factors, genes linked to carbon and amino acid metabolism and abiotic stress resistance. We built a hierarchical regulatory model for O2 that provides an understanding of its pleiotropic biological effects.
National Hospital Discharge Survey: 2005 annual summary with detailed diagnosis and procedure data.

OBJECTIVES This report presents 2005 national estimates and selected trend data on the use of nonfederal short-stay hospitals in the United States. Estimates are provided by selected patient and hospital characteristics, diagnoses, and surgical and nonsurgical procedures performed. Estimates of diagnoses and procedures are presented according to International Classification of Diseases, Ninth Revision, Clinical Modification codes. METHODS The estimates are based on data collected through the National Hospital Discharge Survey. The survey has been conducted annually since 1965. In 2005, data were collected for approximately 375,000 discharges. Of the 473 eligible nonfederal short-stay hospitals in the sample, 444 (94 percent) responded to the survey. RESULTS An estimated 34.7 million discharges from nonfederal short-stay hospitals occurred in 2005. Discharges used 165.9 million days of care and had an average length of stay of 4.8 days. Persons 65 years and over accounted for 38 percent of the hospital discharges and 44 percent of the days of care. The proportion of discharges whose status was described as routine discharge or discharged to the patient's home declined with age, from 91 percent for inpatients under 45 years of age to 41 percent for those 85 years and over. Hospitalization for malignant neoplasms decreased from 1990-2005. The hospitalization rate for asthma was the highest for children under 15 years of age and those 65 years of age and over. The rate was lowest for those 15-44 years of age. Thirty-eight percent of hospital discharges had no procedures performed, whereas 12 percent had four or more procedures performed. An episiotomy was performed during a majority of vaginal deliveries in 1980 (64 percent), but by 2005, it was performed during less than one of every five vaginal deliveries (19 percent).
Perioperative Fluid Utilization Variability and Association With Outcomes: Considerations for Enhanced Recovery Efforts in Sample US Surgical Populations

Objectives:To study current perioperative fluid administration and associated outcomes in common surgical cohorts in the United States. Background:An element of enhanced recovery care protocols, optimized perioperative fluid administration may be associated with improved outcomes; however, there is currently no consensus in the United States on fluid use or the effects on outcomes of this use. Methods:The study included all inpatients receiving colon, rectal, or primary hip or knee surgery, 18 years of age or older, who were discharged from a hospital between January 1, 2008 and June, 30 2012 in the Premier Research Database. Patient outcomes and intravenous fluid utilization on the day of surgery were summarized for each surgical cohort. Regression models were developed to evaluate associations of high or low day-of-surgery fluids with the likelihood of increased hospital length of stay (LOS), total costs, or postoperative ileus. Results:The study showed significant associations between high fluid volume given on the day of surgery with both increased LOS (odds ratio 1.10–1.40) and increased total costs (odds ratio 1.10–1.50). High fluid utilization was associated with increased presence of postoperative ileus for both rectal and colon surgery patients. Low fluid utilization was also associated with worse outcomes. Conclusions:According to results from this review of current practice in US hospitals, fluid optimization would likely lead to decreased variability and improved outcomes.
Iron Regulatory Protein-1 Protects against Mitoferrin-1-deficient Porphyria*

Background: Heme and [Fe-S] cluster assembly are tightly regulated processes that require mitochondrial iron. Results: Loss of mitochondrial iron activates the [Fe-S]-dependent RNA-binding activity of IRP1 that inhibits protoporphyrin biosynthesis. Conclusion: IRP1 forms a critical feedback mechanism, preventing protoporphyrin accumulation under limiting mitochondrial iron conditions. Significance: This study provides evidence linking heme biogenesis to that of [Fe-S] clusters synthesis. Mitochondrial iron is essential for the biosynthesis of heme and iron-sulfur ([Fe-S]) clusters in mammalian cells. In developing erythrocytes, iron is imported into the mitochondria by MFRN1 (mitoferrin-1, SLC25A37). Although loss of MFRN1 in zebrafish and mice leads to profound anemia, mutant animals showed no overt signs of porphyria, suggesting that mitochondrial iron deficiency does not result in an accumulation of protoporphyrins. Here, we developed a gene trap model to provide in vitro and in vivo evidence that iron regulatory protein-1 (IRP1) inhibits protoporphyrin accumulation. Mfrn1+/gt;Irp1−/− erythroid cells exhibit a significant increase in protoporphyrin levels. IRP1 attenuates protoporphyrin biosynthesis by binding to the 5′-iron response element (IRE) of alas2 mRNA, inhibiting its translation. Ectopic expression of alas2 harboring a mutant IRE, preventing IRP1 binding, in Mfrn1gt/gt cells mimics Irp1 deficiency. Together, our data support a model whereby impaired mitochondrial [Fe-S] cluster biogenesis in Mfrn1gt/gt cells results in elevated IRP1 RNA-binding that attenuates ALAS2 mRNA translation and protoporphyrin accumulation.
Prevalence of β2-Glycoprotein I Antibody in Patients with Liver Cirrhosis: Relationship with β2-Glycoprotein I Plasma Levels and Thrombosis

Recently, a semiquantitative enzyme-linked immunoassay for detecting IgG or IgM class autoantibody to β2-GPI for use as an aid in the diagnosis of certain autoimmune or thrombotic disorders. We evaluated the prevalence of anti-β2-GPI antibody and its relation to plasma β2-GPI levels and occurrence of thrombosis in 69 patients with liver cirrhosis. As expected, plasma β2-GPI levels were lower in the patients with liver cirrhosis and correlated with Child classification. Anti-β2-GPI antibodies were positive in 11 (15.9%) patients. However, there were no differences in β2-GPI levels, platelet counts, and thrombosis between positive and negative groups for anti-β2-GPI antibodies.
Low-level resistance to the cephalosporin 3'-quinolone ester Ro 23-9424 in Escherichia coli

Four spontaneous, single-step mutants of Escherichia coli K-12 resistant to low levels of the cephalosporin 3'-quinolone ester Ro 23-9424 were isolated at a frequency of 10(-10) to 10(-11) mutants per CFU plated. The mutants were cross-resistant to both cephalosporin (cefotaxime) and quinolone (fleroxacin) components. Accordingly, they had altered porins and replicative DNA biosynthesis resistant to fleroxacin. There was no increase in beta-lactamase activity when tested with nitrocephin, and the penicillin-binding protein profiles were normal.
Returns to Education and Female Work Force Participation Nexus: Evidence from India

In this paper, we make an attempt to understand whether low labour market returns to education in India are responsible for low female work participation. The National Sample Survey Office (NSSO) Employment Unemployment Survey (EUS) unit level data of India for the year 2011-12 is used to examine the relationship between educational attainment and labour market participation through gender lens. Results show that women’s education has a U-shaped relationship with paid work participation. The probability to participate in the paid labour market shows an increasing trend with education levels higher than compulsory secondary schooling. The labour market returns to education are insignificant and low for lower levels of education. The returns increase significantly along with the increase in educational levels. However, females have a significant lower rate of return for each year of education as compared to men in rural and urban labour markets as well. Though it has been said that increase in female enrolment in schooling is one of the reasons of the recent declining phenomenon of female participation, but our study shows that the low returns to education is another reason for their less participation. The findings therefore suggest that, women need to be educated above secondary level to become visible in the labour market.
Skill not athleticism predicts individual variation in match performance of soccer players

Just as evolutionary biologists endeavour to link phenotypes to fitness, sport scientists try to identify traits that determine athlete success. Both disciplines would benefit from collaboration, and to illustrate this, we used an analytical approach common to evolutionary biology to isolate the phenotypes that promote success in soccer, a complex activity of humans played in nearly every modern society. Using path analysis, we quantified the relationships among morphology, balance, skill, athleticism and performance of soccer players. We focused on performance in two complex motor activities: a simple game of soccer tennis (1 on 1), and a standard soccer match (11 on 11). In both contests, players with greater skill and balance were more likely to perform better. However, maximal athletic ability was not associated with success in a game. A social network analysis revealed that skill also predicted movement. The relationships between phenotypes and success during individual and team sports have potential implications for how selection acts on these phenotypes, in humans and other species, and thus should ultimately interest evolutionary biologists. Hence, we propose a field of evolutionary sports science that lies at the nexus of evolutionary biology and sports science. This would allow biologists to take advantage of the staggering quantity of data on performance in sporting events to answer evolutionary questions that are more difficult to answer for other species. In return, sports scientists could benefit from the theoretical framework developed to study natural selection in non-human species.
Energy-Efficient VLSI Realization of Binary64 Division With Redundant Number Systems

VLSI realizations of digit-recurrence binary division usually use redundant representation of partial remainders and quotient digits. The former allows for fast carry-free computation of the next partial remainder, and the latter leads to less number of the required divisor multiples. In studying the previous relevant works, we have noted that the binary carry-save (CS) number system is prevalent in the representation of partial remainders, and redundant high radix representation of quotient digits is popular in order to reduce the cycle count. In this paper, we explore a design space containing four division architectures. These are based on binary CS or radix-16 signed digit (SD) representations of partial remainders. On the other hand, they use full or partial precomputation of divisor multiples. The latter uses smaller multiplexer at the cost two extra adders, where one of the operands is constant within all cycles. The quotient digits are represented by radix-16 [−9, 9] SDs. Our synthesis-based evaluation of VLSI realizations of the best previous relevant work and the four proposed designs show reduced power and energy figures in the proposed designs at the cost of more silicon area and delay measures. However, our energy-delay product is 26%–35% less than that of the reference work.
Nonlinear Equivalent Magnetic Network of a Linear Permanent Magnet Vernier Machine With End Effect Consideration

A nonlinear equivalent magnetic network (EMN) model is proposed for a linear permanent magnet vernier (LPMV) machine. The meshing method is employed to solve the problem of the modeling of complex flux paths in stator teeth tips. Especially, an end-region model based on the electromagnetic principle is developed to consider the longitudinal end effect of the LPMV machine. The key contribution of this paper is to present a faster and simpler approach to separate the detent force (end force component and cogging force component) than finite-element analysis (FEA). Besides, taking the iron saturation and air-gap flux leakage into account, the proposed model is used to predict the electromagnetic performances of the LPMV machine, such as air-gap flux density, back-electromotive force, cogging force, and thrust force. Finally, through comparisons among the FEA simulations, experimental measurements and EMN analyses, the accuracy and effectiveness of the proposed model are verified.
Properties of peptide chain release factor 2 from Streptomyces coelicolor A3(2): conserved primary structure but no frameshift regulation

A gene was cloned from Streptomyces coelicolor A3(2). It encodes a protein of 368 amino acid residues with a high degree of similarity to prokaryotic release factor 2. However, it has neither an internal stop codon nor the Shine-Dalgarno-like sequence immediately upstream of the assumed frameshift position. The gene is expressed and functional in Escherichia coli as peptide chain release factor 2. The transcription start site is at or adjacent to the translational start site. The size of the mRNA detected by hybridization suggests that the gene (prfB) is monocistronic in S. coelicolor A3(2). However, about 80 bp upstream of the gene there is an operon which is composed of two genes encoding eukaryotic-type serine/threonine kinases.
Two-dimensional cavity-backed angled-dipole array antenna for 28-GHz band

This paper presents a high-gain low-sidelobe two-dimensional cavity-backed angled-dipole array antenna with 64 antennas in an 8 × 8 square grid for 28-GHz applications. This antenna yields broadband characteristics and similar 3-dB beamwidths in the E- and H-planes, and it is chosen for stable operation in a two-dimensional array environment. A nonuniform power distribution is used to excite the array to achieve a low sidelobe level (SLL) in the azimuth planes. The proposed array showed similar scanning performance in the E-and H-planes. It achieved gain exceeding 20.0 dBi and SLL below −18.5 dB for scanning angles up to 40°.
Ranking Disclosure Policies in All‐Pay Auctions

In this paper, we study information disclosure policies in all‐pay auctions with incomplete information. Two symmetric players have either high or low private value. The contest organizer observes players' values ex post, and can commit ex ante to four different symmetric information policies exhaustively: She can fully disclose or conceal the players' types, and she can disclose their types if and only if when both are high or if and only if when both are low. We characterize the unique equilibriums, and completely rank the four policies by various criteria. We find the full concealment policy extracts highest aggregate expected effort, followed by the policy of disclosing types if and only if when both are high. The policy of disclosing types if and only if when both are low induces least aggregate expected effort. Players enjoy highest expected payoffs under the policy of disclosing types if and only if when both are low; the other three policies yield the same expected payoffs to players. In terms of prize allocation efficiency, the full concealment policy is ranked highest and the full disclosure policy is ranked lowest. In between, the other two policies' rankings depend on the probability of high type. (JEL C72, D44, D82, D83, J48).
Plasma thrombospondin‐1 and clinical outcomes in traumatic brain injury

Thrombospondin‐1 (TSP‐1) acts as an anti‐angiogenic factor, and its expression in rat brain is upregulated after intracerebral hemorrhage. The current study was designed to investigate the change of plasma TSP‐1 levels and assess the prognostic predictive effect of plasma TSP‐1 level and it is associated with head trauma severity in the patients with severe traumatic brain injury (STBI).
Primary endovascular treatment of post-irradiated carotid pseudoaneurysm at the skull base with the Pipeline embolization device

Background A post-irradiated carotid pseudoaneurysm at the skull base can cause life-threatening blowout syndrome. Conventional treatments include parent vessel occlusion, endovascular coiling or covered stenting. Use of the Pipeline embolization device (PED) for pseudoaneurysm exclusion at the skull base is not well described. Objective To report the clinical and angiographic outcome after using multiple PEDs to treat recently ruptured radiation-induced carotid pseudoaneurysms at the skull base. Methods Retrospective review of the clinical and angiographic records of patients who received PEDs as primary treatment for skull base carotid pseudoaneurysm between April 1, 2011 to March 31, 2013. Results Seven patients (five men, two women) with a mean age of 58 years (range 47–65) were treated in the study period. Primary treatment with the PED alone, with adjunct coil embolization in two patients, achieved immediate hemostasis in all patients, with no pseudoaneurysm rebleeding after a mean follow-up of 15.3 months (range 4–24 months). One patient had periprocedural cerebral infarction. Delayed internal carotid artery occlusion secondary to in-stent thrombosis occurred in three patients, one of whom had lacunar infarct and two remained asymptomatic. Conclusions Endovascular treatment with the PED was effective in excluding skull base post-irradiated carotid pseudoaneurysms and preventing recurrent blowout. However, the risk of ischemic complications in this group of patients was high and our experience did not support the use of flow diverters as a first-line treatment for this condition.
Potential of energy-oriented network optimisation: Switching off over-capacity in off-peak hours

Mobile communication networks are usually planned to provide some minimum service quality level during peak traffic hours. Consequently, in off-peak hours, when traffic loads are lower, the network is characterised by over-capacity, in the sense that same service quality targets can typically be satisfied with a reduced set of network resources, e.g. sites, carriers, etc. In this paper, we propose a procedure for deriving the potential of energy-oriented network optimisation, and apply this procedure to the case of a UMTS/HSDPA network. Depending on the desired performance target and the energy consumption model, energy savings from energy-oriented network optimisation of up to about 40% are shown to be attainable.
