A recent signature of selection on chromosome 12 with candidate resistance loci against artemisinin derivatives was evident in Ghana and Malawi. …”

Stochastic expectation maximization with variance reduction by Chen, J, Zhu, J, Teh, Y, Zhang, T

“…In this paper, we propose a variance reduced stochastic EM (sEM-vr) algorithm inspired by variance reduced stochastic gradient descent algorithms. We show that sEM-vr has the same exponential asymptotic convergence rate as batch EM. …”

The ecology and evolution of pangenomes by Brockhurst, MA, Harrison, E, Hall, JPJ, Richards, T, McNally, A, Maclean, C

“…Since the first genome-scale comparisons, it has been evident that the genomes of many species are unbound by strict vertical descent: Large differences in gene content can occur among genomes belonging to the same prokaryotic species, with only a fraction of genes being universal to all genomes. …”

Principal component analysis by optimisation of symmetric functions has no spurious local optima by Eftekhari, A, Hauser, R

“…These programs therefore loosely behave like convex problems and can be efficiently solved to global optimality, for example, with certain variants of the stochastic gradient descent. Beyond providing new geometric interpretations and enhancing our theoretical understanding of PCA, our findings might pave the way for entirely new approaches to structured dimensionality reduction, such as sparse PCA and nonnegative matrix factorization. …”

Ecoethical significance of wilderness in Pablo Neruda’s selected poems by Goltaj David Khosravi, Ravichandran Vengadasamy, Raihanah M. M.

“…This paper explores the ecoethical vision and ecological awareness in the selected poems of Pablo Neruda, a Nobel Prize winning poet of Latin American descent who was well known as a political poet. The structural and thematic analysis of the study will focus on the concept of ‘Ethics’ as one of the components of ecopoetry, which is the new brand of nature poetry and one of the components of ecocriticism which investigates the human-nature relationship. …”

Achille and the unhomely pull of atavistic homeland in derek walcott's Omeros by Zargarzadeh, H.

“…Even though essentially Africa is regarded as the ancestral homeland for people of African descent, the uncanny feeling it creates, negates this association. …”

An instrumental study of oral vowels in the Kedah variety of Acehnese by Yusuf, Y.Q., Pillai, S.

“…The first and second formant values of the vowels were extracted and analysed from ten female Malaysians of Acehnese descent living in Kampung Aceh in Kedah. Comparisons with vowels in the Indonesian Acehnese variety were also carried out. …”

Thermal characterization of phase difference among the LP modes in two-mode fibers based on numerical approach by Zaini, Muhammad Khairol Annuar, Lee, Yen Sian, Lim, Kok Sing, Nazal, Nurul Asha Mohd, Yang, Hang Zhou, Ahmad, Harith

“…In this work, we present the use of stochastic parallel gradient descent (SPGD) method for determination of thermal characteristic of the phases of LP11o and LP11e modes in relative to LP01 mode in two-mode fibers. …”

Adaptive linearizing control with neural-network-based hybrid models by Hussain, Mohd Azlan, Ho, P.Y., Allwright, J.C.

“…Online adaptation of the network is performed using steepest descent with a dead zone function. Closed-loop Lyapunov stability analysis for this system has been proven, where it was shown that the output tracking error was confined to a region of a ball, the size of which depends on the accuracy of the neural network models. …”

Decision making for uncertain data in dynamic environment using hybrid method by Shahi, Ahmad, Atan, Rodziah, Sulaiman, Md. Nasir

“…Vast amount of data from a dynamic environment will be very uncertain and the prediction of future behavior of such a situation is very hard and if it is possible, the result will not be accurate and may lead to incorrect predictions, Therefore, for the problem statement we propose a new framework that is called hybrid method based on Fuzzy c-mean clustering and Type-2 fuzzy logic system with gradient descent algorithm for training data that would be applicable in a dynamic environment, the hybrid method is able to manage uncertain data such as outliers and noise to get more accurate results and applicable in dynamic environment as well. …”
