An unusual approach about richness and rarity of leaf-litter ant species is presented here from a dry forest reminiscent in Pantanal province (Chacoan subregion) suggesting the boundaries that defining local and regional scales for this particular ant community. We analysed the frequency of distribution of 170 ant species collected on 262 Winkler’s samples along Serra da Bodoquena National Park, Mato Grosso do Sul state, Brazil and described some ecological mechanisms that made the species richness estimates be highly influenced by species with low frequencies of records in an extent regional of a pristine dry forest. Bayesian inference was conducted to provide if the probability of latitudinal gradient was correlated with the species richness to define alpha diversity.

Nowadays, all different areas in business world agree about the paramount importance of Maintenance Function. At the same time, the progressive worth of the Activity opens a greater number of ways pointed up to the conquest of its scientific status. Considering such issues, this paper deals with the Maintenance Management and the challenges that it has been called to respond, as a result of intricate scenarios where high competition, fast changes in social-economical environments and shortage of natural resources have to be faced by all organizations in search for survival and perennial continuity. Taking into account such concerns, the problems related to organizational Sustainability are analyzed in their typical nuances （environmental, social and economical）, and an integrated model of Maintenance management system is proposed, in order to decisively contribute for the excellence in present and future corporate performance. Based upon a broad revision of the related literature to investigate the practices concerning the usual policies for Maintenance management, this innovative and strategic approach for the Activity is presented, with more extensive and integrated characteristics to be settled in complement to those traditionally used, to assure the business sustainability for all organizations. This model is called "SCM: The Sustainability-Centered Maintenance" and, in order to describe its functional process, influences of factors such as Quality, Training, Physical Resources, Management Performance and Maintenance Policies are herein analysed.

AIM： To study the role of an insertion/deletion polymorphism in the pepsinogen C （PGC） gene, an effective marker for terminal differentiation of the stomach mucosa, in the susceptibility to the development of gastric lesions. METHODS： The study was performed with 99 samples of known gastric lesions and 127 samples without evidence of neoplastic disease. PCR was employed and the 6 polymorphic alleles were amplified： Allele 1 （510 bp）, Allele 2 （480 bp）, Allele 3/4 （450/460 bp）, Allele 5 （400 bp） and Allele 6 （310 bp）. RESULTS： Our results revealed that Allele 6 carriers seemed to have protection against the development of any gastric lesion （OR = 0.34; P 〈 0.001）, non-dysplastic lesions associated with gastric adenocarcinoma such as atrophy or intestinal metaplasia （OR = 0.28; P 〈 0.001） or invasive GC （OR = 0.39; P = 0.004）. CONCLUSION： Our study reveals that the Allele 6 carrier status has a protective role in the development of gastric lesions, probably due to its association with higher expression of PGC. Moreover, the frequency of Allele 6 carriers in the control group is far higher than that obtained in Asian populations, which might represent a genetic gap between Caucasian and Asian populations.

Frequency domain analyses in electromyographic (EMG) signals are frequently applied to assess muscle fatigue and similar variables. Moreover, Fourier-based approaches are typically used for investigating these procedures. Nonetheless, Fourier analysis assumes the signal as stationary which is unlikely during dynamic contractions. As an alternative method, wavelet-based treatments do not assume this pattern and may be considered as more appropriate for joint time-frequency domain analysis. Based on the previous statements, the purpose of the present study was to compare the application of Short-Time Fourier Transform (STFT) and Continuous Wavelet Transform (CWT) to assess muscle fatigue in dynamic exercise of a 1-km of cycling (time-trial condition). The results of this study indicated that CWT and STFT analyses have provided similar fatigue estimates (slope) (p> 0.05). However, CWT application represents lesser dispersion (p 0.05) according to different methods, it is important to note that these responses seem to show greater values for CWT compared to STFT for 2 superficial muscles. Thereby, we are capable of considering CWT as a reliable and useful method to take into consideration when non-stationary or oscillating exercise models are evaluated.

Robot World Cup Initiative (RoboCup) is a worldwide competition proposed to advance research in robotics and artificial intelligence. It has a league called RoboCup soccer devoted for soccer robots, which is a challenge because robots are mobile, fully autonomous, multi-agents, and they play on a dynamic environment. Moreover, robots must recognize the game entities, which is a crucial task during a game. A camera is usually used as an input system to recognize ball, opponents, soccer field, and so on. These elements may be recognized applying some tools of computational intelligence, for example an artificial neural network. This paper describes the application of an artificial neural network on middle size robotic football league, where a multilayer perceptron neural network is trained with the backpropagation algorithm, to classify elements on the image. Each output neuron represents an entity and its output value depends on the current entity that is present on the image. The results show that an artificial neural network successfully classified the entities. They were recognized even when similar color entities were present on the image.

This paper is devoted to the probabilistic stability analysis of a tunnel face excavated in a two-layer soil. The interface of the soil layers is assumed to be positioned above the tunnel roof. In the framework of limit analysis, a rotational failure mechanism is adopted to describe the face failure considering different shear strength parameters in the two layers. The surrogate Kriging model is introduced to replace the actual performance function to perform a Monte Carlo simulation. An active learning function is used to train the Kriging model which can ensure an efficient tunnel face failure probability prediction without loss of accuracy. The deterministic stability analysis is given to validate the proposed tunnel face failure model. Subsequently, the number of initial sampling points, the correlation coefficient, the distribution type and the coefficient of variability of random variables are discussed to show their influences on the failure probability. The proposed approach is an advisable alternative for the tunnel face stability assessment and can provide guidance for tunnel design.
