In this work, event related potentials (ERPs) induced by visual stimuli categorized with different value of affective valence are studied. EEG signals are recorded during visualization of selected pictures belonging to International Affective Picture System (IAPS). A Morlet wavelet filter is used to transform the EEG input space to a topography-time-frequency feature space. Support vector machine-recursive feature elimination (SVM-RFE) is applied for detecting scalp spectral dynamics of interest (SSDOIs) in this feature space, allowing to identify the most relevant time intervals, frequency bands and EEG channels. This feature selection method has proven to outperform the classical t-test in the discrimination of brain cortex regions involved in affective valence processing. Furthermore, the presented combination of feature extraction and selection techniques can be applied as an alternative in other different clinical applications. (C) 2012 Elsevier Ltd.

Attentional Bias Toward Reproduction-Related Stimuli and Fertility Concerns Among Breast Cancer Survivors

Ana Bartolo, Isabel M. Santos, Raquel Guimaraes, Salome Reis, Sara Monteiro

Summary: The study found that biased cognitive processing towards reproduction-related cues exists for all young women, but attentional bias is significantly associated with concerns about partner disclosure of fertility status only for breast cancer survivors. The desire to have a (or another) biological child is also a significant predictor of higher concerns related to fertility potential for all young women.

Summary: This study presents a systematic review of factors associated with distress in elderly cancer patients. The research found that being female, single or widowed, having low income, an advanced diagnosis, functional limitations, comorbidities, and little social support were consistently associated with emotional distress. The impact of age, cancer type, and treatment on anxiety and depression symptoms in elderly patients is still unclear.

Summary: Recent studies have found that nonphase-locked brain activity can reveal cognitive mechanisms that cannot be observed in phase-locked activity. The main aim of this study was to investigate the potential roles of nonphase-locked alpha and gamma activities in cognitive processes. The results showed that nonphase-locked alpha activity is bilaterally represented in the scalp, while nonphase-locked gamma activity exhibits higher desynchronization in the ipsilateral hemisphere.

Summary: The aim of this study was to quantify the proportion of the French population affected by driving anxiety. An online survey was conducted among 5000 French adults, and the results showed that nearly 80% of the sample expressed at least some level of driving anxiety. Women reported higher levels of driving anxiety than men, and younger individuals had higher levels of anxiety. Additionally, individuals living in larger urban areas (such as Paris) and those in lower-qualified occupational categories reported higher levels of driving anxiety on average. These results highlight the extent of driving anxiety in France.

Khuong Le Nguyen, Hoa Thi Trinh, Saeed Banihashemi, Thong M. Pham

Summary: This study investigated the influence of input parameters on the shear strength of RC squat walls and found that ensemble learning models, particularly XGBoost, can effectively predict the shear strength. The axial load had a greater influence than reinforcement ratio, and longitudinal reinforcement had a more significant impact compared to horizontal and vertical reinforcement. The performance of XGBoost model outperforms traditional design models and reducing input features still yields reliable predictions.

Learning high-dependence Bayesian network classifier with robust topology

Limin Wang, Lingling Li, Qilong Li, Kuo Li

Summary: This paper discusses the urgency of learning complex multivariate probability distributions due to the increase in data variability and quantity. It introduces a highly scalable classifier called TAN, which utilizes maximum weighted spanning tree (MWST) for graphical modeling. The paper theoretically proves the feasibility of extending one-dependence MWST to model high-dependence relationships and proposes a heuristic search strategy to improve the fitness of the extended topology to data. Experimental results demonstrate that this algorithm achieves a good bias-variance tradeoff and competitive classification performance compared to other high-dependence or ensemble learning algorithms.
