Introduction: generic features of quinone-binding sites (Q sites) Quinones form a central link between protein complexes in most types of electron-transfer chain. More than 50 distinct types of Q site associated with respiratory and photosynthetic electron-transfer complexes have been identified to date. Most involve rather loose and dynamic binding of quinone, and for these Q sites inhibitory ...

In this article we learn significant local appearance features for visual classes. Generic feature detectors are obtained by unsupervised learning using clustering. The resulting clusters, referred to as “classtons”, identify the significant class characteristics from a small set of sample images. The classton channels mark these characteristics reliably using a probabilistic cluster representa...

Scholarly mails apparently display stable conventional principles as an emerging genre. Thus, contributors should structure their electronic mails appropriately when writing for purposes of discussing professional topics. However, this requirement plunges many a scholar in dilemma as to how to go about this vital undertaking without written structural norms in electronic mail communication. Thi...

We propose a simple, yet effective approach for spatiotemporal feature learning using deep 3-dimensional convolutional networks (3D ConvNets) trained on a large scale supervised video dataset. Our findings are three-fold: 1) 3D ConvNets are more suitable for spatiotemporal feature learning compared to 2D ConvNets; 2) A homogeneous architecture with small 3 × 3 × 3 convolution kernels in all lay...

Considering that there are many different syntactic and semantic theories, this article is concerned with entering enough information into a generic lexicon to provide each of these theories with what it needs to work. Providing information for different uses implies organizing that information into a hierarchy of pieces of information. The first part of the article is devoted to this question....

this study investigated the relative effects of deductive and inductive form-focused instruction (ffi) on the acquisition of 4 non-generic definite article uses(cultural, situational, structural, and textual) as assessed by explicit and implicit outcome measures. the tests utilized to assess efl learners' acquisition of definite article uses were timed and untimed grammaticality judgment tests....

As a distinct socially constructed genre, wedding invitations (WIs) offer a fruitful site for investigating how two areas of genre knowledge (i.e., form and content) change over time under the influence of sociocultural forces. Through the examination of 100 Iranian WIs dating from 1970s to the present time, the study investigated the trajectories of change through time within the social semiot...
