    Alignment of helical membrane protein sequences using AlignMe

    Get PDF
    Few sequence alignment methods have been designed specifically for integral membrane proteins, even though these important proteins have distinct evolutionary and structural properties that might affect their alignments. Existing approaches typically consider membrane-related information either by using membrane-specific substitution matrices or by assigning distinct penalties for gap creation in transmembrane and non-transmembrane regions. Here, we ask whether favoring matching of predicted transmembrane segments within a standard dynamic programming algorithm can improve the accuracy of pairwise membrane protein sequence alignments. We tested various strategies using a specifically designed program called AlignMe. An updated set of homologous membrane protein structures, called HOMEP2, was used as a reference for optimizing the gap penalties. The best of the membrane-protein optimized approaches were then tested on an independent reference set of membrane protein sequence alignments from the BAliBASE collection. When secondary structure (S) matching was combined with evolutionary information (using a position-specific substitution matrix (P)), in an approach we called AlignMePS, the resultant pairwise alignments were typically among the most accurate over a broad range of sequence similarities when compared to available methods. Matching transmembrane predictions (T), in addition to evolutionary information, and secondary-structure predictions, in an approach called AlignMePST, generally reduces the accuracy of the alignments of closely-related proteins in the BAliBASE set relative to AlignMePS, but may be useful in cases of extremely distantly related proteins for which sequence information is less informative. The open source AlignMe code is available at https://sourceforge.net/projects/alignme​/, and at http://www.forrestlab.org, along with an online server and the HOMEP2 data set

    Cacingan merupakan kondisi di dalam tubuh manusia terdapat cacing. Cacingan dapat mengakibatkan menurunnya kondisi kesehatan, gizi, kecerdasan, dan produktivitas penderitanya sehingga secara ekonomi banyak menyebabkan kerugian. Cacingan bisa terjadi pada orang dewasa namun lebih banyak kejadian terjadi pada usia anak-anak. Hal ini dapat disebabkan anak yang kurang menjaga kebersihan diri terutama pada saat mereka sedang bermain. Penelitian ini bertujuan untuk mengetahui pengetahuan ibu tentang gambaran tingkat pengetahuan ibu tentang ascariasis (cacingan) pada Balita di Wilayah Kerja Puskesmas Siwuluh Kabupaten Brebes. Metode penelitian yang digunakan adalah deskriptif dengan metode survey yang bertujuan untuk mengetahui gambaran pengetahuan ibu tentang cacingan pada Balita di Wilayah Puskesmas Siwuluh.

    Today the application of CSR becomes increasingly important for the company. CSR has become a necessity for companies. The company's presence in the midst of society's dependence coined by people who are nearby. The relationship between the company and the community share the two sides of a coin that can not be separated. CSR also contributed positively to the relationship between the company and the community. Company as part of the community has a role in the community. Companies are not only economic benefits hunt alone, but also a concern for the environment and social welfare. State-Owned Enterprises (SOEs) have a strategic role and functions, as executor of public services, balancing large private forces, and helped small business development. SOE CSR role in the preservation of rivers such as helping the government to regenerate the river Cikapundung as a public space and also regarding the handling of flooding in the area around the River Cikapundung Bandung. To find the best solution in the structuring of public space in this Cikapundung riverbank, is very important to develop a policy of restoration of the river that can balance the interests of economic, social and environmental sustainability sustainable

    Evaluation of Machine Learning Models for Breast Cancer Diagnosis Via Histogram of Oriented Gradients Method and Histopathology Images

    Get PDF
    Breast cancer is the main death rate from malignant growth worldwide and the most frequently diagnosed type of cancer in females. Machine learning systems have been developed to assist in the accurate detection of cancer. There are numerous methods for cancer detection. But histopathological images are thought to be more precise. In this study, we used the HOG features extractor to extract statistical features from histopathology images of invasive ductal carcinoma. We chose the following images at random from the histopathology images: 100, 200, 400, 1000, and 2000. These statistical features were then used to train several algorithms, including the decision tree, quadratic discriminant analysis, extra randomized trees, gradient boosting, gaussian process classifier, naive bayes, nearest centroid, multilayer perceptron, and support vector machine, to identify whether or not the images depict cancerous or noncancerous growth. The algorithms' performance was evaluated depending on the specificity, accuracy, sensitivity, precision, F1_score, and AUC. The algorithms used worked best when the number of images was set to 100. As the number of images went up, their effectiveness went down

    Capacities of Grassmann channels

    Full text link
    A new class of quantum channels called Grassmann channels is introduced and their classical and quantum capacity is calculated. The channel class appears in a study of the two-mode squeezing operator constructed from operators satisfying the fermionic algebra. We compare Grassmann channels with the channels induced by the bosonic two-mode squeezing operator. Among other results, we challenge the relevance of calculating entanglement measures to assess or compare the ability of bosonic and fermionic states to send quantum information to uniformly accelerated frames.Comment: 33 pages, Accepted in Journal of Mathematical Physics; The role of the (fermionic) braided tensor product for quantum Shannon theory, namely capacity formulas, elucidated; The conclusion on the equivalence of Unruh effect for bosons and fermions for quantum communication purposes made clear and even more precis

    A critical look at an Islamic Gold investment account

    This article assesses an Islamic gold investment account offered by an Islamic bank in Malaysia and analyses its pros and cons. We look into the product’s relative advantages and disadvantages compare to some other Islamic deposit products and conventional gold accounts. In process of the assessment we also come across some Shari’ah compliance related issues and some practices which needs to be scrutinized from Shari’ah, economic and social perspectives. Overall, our findings suggest the account to be worthwhile investment instrument for long-term saving instrument and promising venture at times of boom in gold prices. However, the account is considered as a risky and unfavorable investment when gold price is on fall or if the customer intends to keep his deposits for a brief period. Finally, we pose some questions to the reader to ponder upon about some possible implication of the product for the Islamic bank, its customer or the society at large

    Two-term Weyl-type asymptotic law for the eigenvalues of one-dimensional quasi-relativistic Hamiltonian (-h^2 c^2 d^2/dx^2 + m^2 c^4)^(1/2) + V_well(x) (the Klein-Gordon square-root operator with electrostatic potential) with the infinite square well potential V_well(x) is given: the n-th eigenvalue is equal to (n pi/2 - pi/8) h c/a + O(1/n), where 2a is the width of the potential well. Simplicity of eigenvalues is proved. Some L^2 and L^infinity properties of eigenfunctions are also studied. Eigenvalues represent energies of a `massive particle in the box' quasi-relativistic model.Comment: 40 pages, 4 figures; minor correction
