    Abstract Bladder metastasis from cutaneous melanoma is a rare pathology. A 79-year-old woman presented to the haematuria clinic on account of painless visible haematuria. Ten years prior to this index presentation, she was diagnosed with melanoma on her right thigh following a total excision of the skin lesion. Cystoscopy showed a pigmented bladder tumour, and the histology report following a transurethral resection was consistent with metastatic melanoma, and further imaging revealed metastasis to the lungs, adrenals, and lymph nodes.

    Abstract Objective: The P300 speller is intended to restore communication to patients with advanced neuromuscular disorders, but clinical implementation may be hindered by several factors, including system setup, burden, and cost. Our goal was to develop a method that can overcome these barriers by optimizing EEG electrode number and placement for P300 studies within a population of subjects.
    Methods: A Gibbs sampling method was developed to find the optimal electrode configuration given a set of P300 speller data. The method was tested on a set of data from 15 healthy subjects using an established 32-electrode pattern. Resulting electrode configurations were then validated using online prospective testing with a naïve Bayes classifier in 15 additional healthy subjects.
    Results: The method yielded a set of four posterior electrodes (PO₈, PO₇, POZ, CPZ), which produced results that are likely sufficient to be clinically effective. In online prospective validation testing, no significant difference was found between subjects' performances using the reduced and the full electrode configurations.
    Conclusions: The proposed method can find reduced sets of electrodes within a subject population without reducing performance.
    Significance: Reducing the number of channels may reduce costs, set-up time, signal bandwidth, and computation requirements for practical online P300 speller implementation.

    Abstract The P300 Speller is a common brain-computer interface communication system. There are many parallel lines of research underway to overcome the system's low signal to noise ratio and thereby improve performance, including using famous face stimuli and integrating language information into the classifier. While both have been shown separately to provide significant improvements, the two methods have not yet been implemented together to demonstrate that the improvements are complimentary. The goal of this study is therefore twofold. First, we aim to compare the famous faces stimulus paradigm with an existing alternative stimulus paradigm currently used in commercial systems (i.e., character inversion). Second, we test these methods with language model integration to assess whether different optimization approaches can be combined to further improve BCI communication. In offline analysis using a previously published particle filter method, famous faces stimuli yielded superior results to both standard and inverting stimuli. In online trials using the particle filter method, all 10 subjects achieved a higher selection rate when using the famous faces flashing paradigm than when using inverting flashes. The improvements achieved by these methods are therefore complementary and a combination yields superior results to either method implemented individually when tested in healthy subjects.

    Abstract Oilseed crops occupy an important place in Indian economy next to food grains. India ranks first in the world in respect of area, production and productivity of castor crop during 2009–2010 as 8.59 lack hectares areas, 11.90 lack tones production and 1385 kg/ha productivity (Anon., 2011a). Castor being one of the important oilseed crop in Sabarkantha district. The area under hybrid castor in this district was 1, 47, 425 hectares with a production about 1, 25, 700 Metric tones and productivity of 1712 kg/ha during 2010–2011 (Anon., 2011). But the harvested yield of castor crop in the research station was recorded as 2230 to 3000 kg/ha. The study was conducted in three talukas of Sabarkantha districts in the year 2011–12. The majority of castor growers were found in medium level of category with respect to age (57.50%), land holding (89.17%), annual income (59.17%), extension contact (58.33%), sources of information (69.17%), economic motivation (70.83%), scientific orientation (67.50%), risk preference (76.66%) and level of knowledge (69.17%). Further, The majority (62.50%) of castor growers were educated from primary to secondary school, (64.17%) were having tube-well irrigation facility, (90%) were having membership in social organization and (80%) were having medium to high level of innovativeness. Majority of the castor growers (67.50%) were having medium level of adoption of recommended hybrid castor cultivation technology. The results of correlation analysis indicated that out of 13 independent variables, eleven independent variables viz.; education, land holding, annual income, social participation, extension contact, sources of information, economic motivation, scientific orientation, Risk preference, innovativeness and knowledge level were found positively and significantly correlated with extent of adoption of recommended hybrid castor cultivation technology by the castor growers.

But the harvested yield of castor crop in the research station was recorded as 2230 to 3000 kg/ha. The study was conducted in three talukas of Sabarkantha districts in the year 2011–12. The major constraints faced by the castor growers in adoption of recommended hybrid castor cultivation technology were; unavailability of certified seed (87.5%), high costs of inputs (80.00%), insufficient irrigation facility (71.67%), high rate and irregular supply of electricity (70.00%), low market price of produce (67.50%), high wages and shortage of labour at the time of picking (62.50%), non-availability of technical guidance (54.17%) and non-availability of finance (50.83%) which were ranked as I, H, HI, IV, V, VI, VII and VIII, respectively.

    Abstract The P300 speller is a common brain-computer interface (BCI) application designed to communicate language by detecting event related potentials in a subject's electroencephalogram (EEG) signal. Information about the structure of natural language can be valuable for BCI communication systems, but few attempts have been made to incorporate this domain knowledge into the classifier. In this study, we treat BCI communication as a hidden Markov model (HMM) where hidden states are target characters and the EEG signal is the visible output. Using the Viterbi algorithm, language information can be incorporated in classification and errors can be corrected automatically. This method was first evaluated offline on a dataset of 15 healthy subjects who had a significant increase in bit rate from a previously published naïve Bayes approach and an average 32% increase from standard classification with dynamic stopping. An online pilot study of five healthy subjects verified these results as the average bit rate achieved using the HMM method was significantly higher than that using the naïve Bayes and standard methods. These findings strongly support the integration of domain-specific knowledge into BCI classification to improve system performance and accuracy.

    Abstract The work done in this paper, proposes a complex Laplacian-based distributed control scheme for convergence in the multi-agent network. The proposed scheme has been designated as cascade formulation. The proposed technique exploits the traditional method of organizing large scattered networks into smaller interconnected clusters to optimize information flow within the network. The complex Laplacian-based approach results in a hierarchical structure, with formation of a meta-cluster leading other clusters in the network. The proposed formulation enables flexibility to constrain the eigen spectra of the overall closed-loop dynamics, ensuring desired convergence rate and control input intensity. The sufficient conditions ensuring globally stable formation for proposed formulation are also asserted. Robustness of the proposed formulation to uncertainties like loss in communication links and actuator failure has also been discussed. The effectiveness of the proposed approach is illustrated by simulating a finitely large network of thirty vehicles.
