Memoria para dimensiones componentes de imágenes, en una tarea de reconocimiento serial

A serial recognition experiment was conducted in which six images were presented in sequence (selected randomly from a total of 128 which could be generated by the combination of seven dimensions with two categories each). It was demonstrated that the subjects correctly remember only a few complete visual patterns; but an analysis of the number of correct answers for the variables of each image shows that: a) a significantly high number of categories in all the dimensions are remembered correctly; b) there are significant differences between the number of correct answers for the dimensions (the means of the number of categories correctly remembered in the different dimensions are very high, but differ amongst themselves, the order of recognition being: line, form, position, quantity, colour, width, and length); c) there are no significant differences according to sex. These results suggest that a great deal of information is recalled, and that the memory is selective, remembering the component variables of a visual pattern in different ways, which would confirm the model of the dependence of the recognition memory on visual patterns rather than more complex cognitive processes.
Frequent occurrence of identical heavy and light chain Ig rearrangements.

Single-cell PCR analyses of expressed Ig H and L chain sequences presented here show that certain rearrangements occur repeatedly and account for a major segment of the well-studied repertoire of B-1 cell autoantibodies that mediate the lysis of bromelain-treated mouse erythrocytes, i.e. antibodies reactive with phosphatldyicholine (PtC). We repeatedly isolated at least 10 different types of VH region rearrangements, involving three distinct germline genes, among FACS-sorted PtC-binding B-1 cells from three strains of mice (C57BL/6J, BALB/c and C.B-17). The predominant rearrangement, VH11-DSP-JH1 (VH11 type 1), has been previously found in anti-PtC hybridomas in several studies. We show that within each of six mice from two strains (C57BL/6J and BALB/c), unique instances of IgH/IgL pairing arose either from different B cell progenitors prior to IgH rearrangement or from pre-B cells which expanded after IgH rearrangement but prior to IgL rearrangement. Together with other recurrent rearrangements described here, our findings demonstrate that clonal expansion of mature B cells cannot account for all repeated rearrangements. As suggested by initial studies of dominant idiotype expression, these findings confirm that clonal expansion is only one of the mechanisms contributing to the establishment of recurrent rearrangements.
COM-LOC: A distributed range-free localization algorithm in wireless networks

This paper investigates distributed range-free localization in wireless networks using a communication protocol called sum-dist which is commonly employed by localization algorithms. With this protocol, the reference nodes flood the network in order to estimate the shortest distance between the reference and blind nodes. Existing localization algorithms that use this communication protocol only evaluate the shortest distance. Our approach is somewhat different in that we optimize the localization performance for this communication protocol. We present a new algorithm called COM-LOC which exploits a certain part of the information inherent in the protocol that other algorithms consider as redundant or false information. We show that the use of this additional part of information increases the performance compared to other range-free algorithms by 68% to 206%. Other comparisons with several RSS-based localization algorithms show that COM-LOC outperforms these algorithms under a wide range of conditions, while keeping the communication costs equal.

Local Health Departments and the Challenge of Chronic Disease: Lessons From California

The essential role local health departments have played in the control of infectious diseases has not been matched with an equivalent contribution in prevention of chronic diseases. Local health departments have attempted to define and build that capacity, but they have been confronted with budget cuts and competing public health priorities, most notably bioterrorism preparedness. This article is based on interviews with local health officials and describes some of the common ways local health departments in California have forged ahead to develop the capacity to engage in comprehensive approaches to chronic disease prevention in spite of the challenges. Additionally, the article highlights future considerations that need to be addressed if these promising trends in chronic disease prevention are to become more widespread.
Recurrent convolution neural networks for classification of protein-protein interaction articles from biomedical literature

Text classification (TC) is a task that assigns a text to one or more classes and predefined categories. Constructing text classifiers with high accuracy is a vital task in biomedical field, given the wealth of information hidden in unlabelled documents. Because of large feature spaces, traditionally discriminative approaches, such as logistic regression and support vector machines with n-gram and semantic features have been utilizedfor biomedical text classification. In this study, we propose Recurrent Convolution Neural Networks (RCNN) based automated technique for classifying protein-protein interaction (PPI) articles. In RCNN model we utilized a recurrent structure to detain the contextual information from word embedding features. Max pooling layer was configured to extract important semantic keywords from the text. We evaluated our approach on two benchmark PPI datasets BioCreative II and BioCreative III. An experimental results show that RCNN based protein-protein interaction classification approach performs better than other state of the art approaches.

Hispanic Bachelor’s Degree Recipients in Connecticut: Effect of Major Field of Study on Expected Starting Salaries

Hispanics’ earnings remain below those of Whites, even after controlling for educational attainment. This article explores the effect of college major on estimated starting salaries of White and Hispanic bachelor’s-degree recipients from Connecticut colleges and universities. Results indicate that while the earnings gap between Hispanic and White workers will decrease as bachelor’s-degree attainment of Hispanics increases, differences in the distributions of students across college majors will mitigate that decrease. Las ganancias de individuos hispanos se mantienen más bajas que las de individuos blancos, aún después de controlar por educación obtenida. Este manuscrito explora el efecto de la especialidad en carrera o licenciatura, en los salarios iniciales estimados en estudiantes blancos e hispanos que recibieron su grado universitario en colegios y universidades de Connecticut. Los resultados indican que mientras que la brecha en ganancias entre trabajadores hispanos y blancos disminuirá conforme hispanos logran aumentar su graduación universitaria, las diferencias en las distribuciones de estudiantes a través de la especialidad mitiga aquella disminución.
Spinopelvic Alignment by Different Surgical Methods in the Treatment of Degenerative Sagittal Imbalance of the Lumbar Spine

Study Design: A retrospective comparative study. Objective: To compare pedicle subtraction osteotomy (PSO) and iliac fixation (ILF) without osteotomy as methods of correcting lumbar spine deformities due to degenerative sagittal imbalance (DSI) through the evaluation of the changes in spinopelvic alignment. Summary of Background Data: Many papers have reported the surgical results after PSO and ILF for patients with fixed adult deformities. However, little is known about the difference between PSO and ILF corrections of spinopelvic alignment in adults with DSI. Methods: DSI patients who had undergone PSO or ILF with a minimum of 2-year follow-up (FU) were retrospectively studied in PSO (n=30) or ILF (n=25) groups. Lumbar lordosis (LL), thoracic kyphosis (TK), and sagittal vertical axis (SVA) were measured as spinal parameters and pelvic incidence (PI), sacral slope (SS), and pelvic tilt (PT) were used as measurements of pelvic parameters. Clinical outcomes were evaluated using a visual analogue scale (VAS) and Oswestry Disability Index (ODI) scores. Results: There were no statistically significant differences between the PSO and ILF groups with regard to age and fused segments, but there were significant differences in operative time and estimated blood loss. Concerning spinal parameters, there were significant increases of LL and TK in PSO group immediate postoperatively (LL: P=0.014, TK: P=0.017) and at the 2-year FU (LL: P=0.021, TK: P=0.022), but no significant difference in SVA was evident between the 2 groups. Within the pelvic parameters, there was a significant increase of SS and decrease of PT in the ILF group immediate postoperatively (SS: P=0.013, PT: P=0.009) and at the 2-year FU (SS: P=0.024, PT: P=0.027), but the PI in both groups was not changed after surgery and there was no significant difference between 2 groups. VAS and ODI were significantly improved after surgery in both groups. Conclusions: The PSO group was better than the ILF group in the correction of the LL and TK, but not with regard to the pelvic parameters. The ILF group was superior in the correction of the pelvic orientation as compared with the PSO group when the PI was constant after surgery. Ultimately, ILF effectively achieves better correction of the pelvic parameters (SS and PT).
After secondary school, what? The transition of deaf young people from school to independent living

Abstract This paper presents some of the findings of the first wave of a national longitudinal study on the transition of deaf young people from school to adult life. The baseline data were gathered on 184 year 11 deaf pupils across England over the course of 15 months. The findings presented focus on the range of activities provided to pupils as a part of the transition planning process, parental involvement in this process, pupils' school experiences, and pupils' and parents' expectations and aspirations about the future.
Multi-Factor Gegenbauer Processes and European Inflation Rates

In this paper we specify a multi-factor long-memory process that enables us to estimate the fractional differencing parameters at each frequency separately, and adopt this framework to model quarterly prices in three European countries (France, Italy and the UK). The empirical results suggest that inflation in France and Italy is nonstationary. However, while for the former country this applies both to the zero and the seasonal frequencies, in the case of Italy the nonstationarity comes exclusively from the long-run or zero frequency. In the UK, inflation seems to be stationary with a component of long memory at both the zero and the semi-annual frequencies, especially at the former.
Differential Antigen Processing by Dendritic Cell Subsets in Vivo

Dendritic cells (DCs) process and present self and foreign antigens to induce tolerance or immunity. In vitro models suggest that induction of immunity is controlled by regulating the presentation of antigen, but little is known about how DCs control antigen presentation in vivo. To examine antigen processing and presentation in vivo, we specifically targeted antigens to two major subsets of DCs by using chimeric monoclonal antibodies. Unlike CD8+ DCs that express the cell surface protein CD205, CD8– DCs, which are positive for the 33D1 antigen, are specialized for presentation on major histocompatibility complex (MHC) class II. This difference in antigen processing is intrinsic to the DC subsets and is associated with increased expression of proteins involved in MHC processing.
Illumination-invariant Image-based Environment Representations for Cognitive Mobile Robots Using Intrinsic Images

Image-based scene representations enable a cognitive robot to make a realistic prediction of its environment. Hence, it is able to rapidly detect changes by comparing a virtual image generated from previously acquired reference images and its current observation. This facilitates surprise detection and attentional control to novel events ([1]). However, illumination effects can impair attentional control if the robot does not take them into account. To address this issue, we present in this paper an approach for the acquisition of illumination-invariant scene representations. Using multiple spatial image sequences which are captured under varying illumination conditions we render virtual images from each sequence at a series of dense viewpoints and recover intrinsic images of the scene. Experimental results show high-quality images which are free of illumination effects.
The Size of Endotracheal Tube and Sore Throat after Surgery: A Systematic Review and Meta-Analysis

Background Recent studies showed that sore throat following endotracheal intubation was a common problem following surgery. The objective of this systematic review and meta-analysis of published randomized controlled trials (RCTs) or cohort studies was to estimate whether the size of endotracheal tube (ETT) affects the incidence of postoperative sore throat (POST) after general anesthesia. Methods The following databases were searched electronically: PubMed (updated to Dec 2012), EMBASE (updated to 15 Dec 2012), Google scholar, World Health Organization International Clinical Trials Registry Platform (Jul 2011), Chinese BioMedical Literature Database (1978 to Jul 2011), and China National Knowledge Infrastructure (1994 to Jul 2011). Studies comparing the size of endotracheal tube for elective surgery were included. Results Three trials with a total of 509 female patients were included in the current analysis. The size of ETT used were 6.0 mm and 7.0 mm. Pooled studies from these trials showed that the smaller size of ETT (6.0 mm) significantly decreased the incidence of POST in post-anesthesia care unit (PACU) (RR = 0.56, 95% CI 0.42–0.75, P<0.01) and at 24 h after surgery (RR = 0.69, 95% CI 0.48–0.99, P<0.05). A smaller size of ETT (6.0 mm) was associated with a lower incidence of PH in PACU (RR = 0.69, 95% CI 0.55–0.87, P<0.01), but did not affect the incidence of PH at 24 h after surgery (RR = 0.73, 95% CI 0.46–1.15, P>0.05). Conclusion Our meta-analysis suggests that patients under general anesthesia with a smaller size of ETT (6.0 mm) were associated with a lower incidence of POST in female patients. More studies with adequate numbers of patients were warranted to evaluate other size of ETT on the incidence of PH and POST after general surgery among different populations.
Black and White Unite or Flight? The racialised dimension of schooling and parental choice

Abstract In the late 1980s UK education witnessed a few highly publicised, controversial and contentious cases of white parents successfully campaigning to have their children educated in predominantly white schools. Since then educational reforms have sought to give parents even greater choice of school, while discussion around white parental choice and ‘race’ has remained largely silent. This paper reopens that debate by examining the extent to which ‘race’ is a factor in white parents’ choice of school. It draws on the quantitative and qualitative findings of the Parental and School Choice Interaction (PASCI) Study, a 3‐year longitudinal investigation into the interaction between parental choice of school and school decision‐making, funded by the UK Economic and Social Research Council. The paper concludes by discussing the complex picture arising from the data and the implications of the findings for education policy.
Lack of prognostic significance of SOCS-1 expression in colorectal adenocarcinomas.

INTRODUCTION Recent studies have indicated that down-regulation of the suppressor of cytokine signaling-1 (SOCS-1) gene results in tumor formation and that SOCS-1 acts as a tumor suppressor gene. SOCS-1 has been also suggested to function as a tumor suppressor with colorectal cancer. OBJECTIVES In the present study, we aimed to determine the association of SOCS-1 expression in colorectal cancer tissues with clinicopathologic characteristics immunohistochemically and also to identify its prognostic significance. MATERIALS AND METHODS SOCS-1 expression was studied immunohistochemically in 67 patients diagnosed with resected colorectal carcinomas and 30 control subjects. RESULTS SOCS-1 expression was found in 46.3% of tumor tissues and 46.7% of the control group. Statistical analyses did not establish any significant association between SOCS-1 expression and clinicopathologic characteristics. Also, no significant association with SOCS-1 expression was found using progression-free survival and overall survival analyses (p=0.326 and p=0.360, respectively). CONCLUSIONS Our results show that SOCS-1 has no prognostic significance in colorectal cancer.
Artificial Intelligent Based Human Motion Pattern Recognition and Prediction for the Surface Electromyographic Signals

In this research, the artificial intelligent method based human motion pattern recognition for surface electromyographic (EMG) signal is proposed. As the EMG signal is a measurement of anatomical and physiological characteristic of the given muscle, the macroscopical movement patterns of the human body can be classified and recognized. By using the technology of wavelet packet transformation, the high-frequency noises can be eliminated effectively and the characteristics of EMG signals can be extracted. Auto-regressive model is adopted to effectively simulate the stochastic and non-stationary time sequences using a series of auto-regressive coefficients with a typical order. Artificial neural network is utilized to distinguish the different force levels in the game of arm wrestling. The efficiency of the proposed methods are proved by experiment results.
Glyceraldehyde-3-Phosphate Dehydrogenase of Streptococcus oralis Functions as a Coadhesin for Porphyromonas gingivalis Major Fimbriae

ABSTRACT Cohesive interactions between Porphyromonas gingivalis and plaque-forming bacteria, such as Streptococcus oralis, are considered to play an important role in the colonization of P. gingivalis in periodontal sites. Although P. gingivalis fimbriae have been reported to mediate coaggregation with S. oralis, the S. oralis molecule involved has not been identified. We identified the coadhesin of S. oralis ATCC 9811 and purified it by affinity column chromatography. We found that the molecular mass of the purified protein was approximately 40 kDa. Dot blot and Western blot assays showed binding of the 40-kDa protein to P. gingivalis fimbriae. Further, turbidimetric assays showed that the coadhesin inhibited coaggregation between P. gingivalis and S. oralis in a dose-dependent manner. Analyses of the amino-terminal sequences of the protein and its lysyl endopeptidase-cleaved fragments revealed that the coadhesin was identical to glyceraldehyde-3-phosphate dehydrogenase (GAPDH). Next, we cloned the gene that encodes S. oralis GAPDH and found that the sequence had a high degree of homology with the sequences of GAPDHs of various bacteria, including Streptococcus gordonii and Fusobacterium nucleatum. To confirm the contribution of S. oralis GAPDH to the interaction with P. gingivalis, a recombinant GAPDH protein was generated in Escherichia coli; this protein bound to P. gingivalis fimbriae and had an inhibitory effect on coaggregation. These results suggest that S. oralis GAPDH functions as a coadhesin for P. gingivalis fimbriae. In addition, considering the high degree of homology of the GAPDHs of various bacteria, those of other plaque-forming bacteria also may contribute to the colonization of P. gingivalis.
VCG Redistribution with Gross Substitutes

For the problem of allocating resources among multiple strategic agents, the well-known Vickrey-Clarke-Groves (VCG) mechanism is efficient, strategy-proof, and it never incurs a deficit. However, in general, under the VCG mechanism, payments flow out of the system of agents, which reduces the agents' utilities. VCG redistribution mechanisms aim to return as much of the VCG payments as possible back to the agents, without affecting the desirable properties of the VCG mechanism. Most previous research on VCG redistribution mechanisms has focused on settings with homogeneous items and/or settings with unit-demand agents. In this paper, we study VCG redistribution mechanisms in the more general setting of combinatorial auctions. We show that when the gross substitutes condition holds, we are able to design mechanisms that guarantee to redistribute a large fraction of the VCG payments.
