Orientation-selective cells--cells that are selectively responsive to bars and edges at particular orientations--are a salient feature of the architecture of mammalian visual cortex. In the previous paper of this series, I showed that such cells emerge spontaneously during the development of a simple multilayered network having local but initially random feedforward connections that mature, one...

Certain Drosophila embryonic epidermal cells construct actin-based protrusions, called denticles, which exhibit stereotyped, column-specific differences in size, density and hook orientation. This precise denticle pattern is conserved throughout all drosophilids yet studied, and screening for mutations that affect this pattern has been used to identify genes involved in development and signalin...

this study extends prior researches by exploring the effect of organizational orientations on export performance. building on the already extensive literature, we developed a model of relationship. a total of 120 usable questionnaires were received from the iranian food industry smes. the results indicated that entrepreneurial orientation, market orientation and learning orientation positively ...

We derive generalized spin models for the development of feedforward cortical architecture from a Hebbian synaptic learning rule in a two layer neural network with nonlinear weight constraints. Our model takes into account the effects of lateral interactions in visual cortex combining local excitation and long range effective inhibition. Our approach allows the principled derivation of developm...

Τhe bidirectional relationship between cortical microtubule orientation and cell wall structure has been extensively studied in elongating cells. Nevertheless, the possible interplay between microtubules and cell wall elements in meristematic cells still remains elusive. Herein, the impact of cellulose synthesis inhibition and suppressed cell elongation on cortical microtubule orientation was a...

The decade between 1998 and 2008 saw rapid increases in research on adolescent sexual orientation development and related health issues, both in quantity and in quality of studies. While much of the research originated in North America, studies from other countries also contributed to emerging understanding of developmental trajectories and social influences on the health of sexual minority ado...

In Sorghum bicolor, perturbations in reproductive development observed following salt-treatment also influence progeny grown in the absence of NaCl. However, a developmental reversion of these modifications may be observed throughout two successive generations. This response, termed canalization, does not spontaneously occur following growth in the absence of NaCl, but is triggered by the level...

The paper contains a discussion of the modification of Rotter's Internal External Scale into the three scales of Internal, Powerful Others, and Chance orientations. The tripartite, multidimensional view of locus of control was developed because the validity and usefulness of Rotter's lumping expectancies of fate, chance, and powerful others together under the rubric of external control were que...

Myoblasts aggregate, differentiate and fuse to form skeletal muscle during both embryogenesis and tissue regeneration. For proper muscle function, long-range self-organization of myoblasts is required to create organized muscle architecture globally aligned to neighboring tissue. However, how the cells process geometric information over distances considerably longer than individual cells to sel...

-Communication complexity scale (CCS)Brady et al., 2012 [1]was developed to assess the communication of individuals with intellectual disabilities and developmental disabilities who are mostly presymbolic communicators in the context of examiner-child scripted interaction. In the present study, CCS was adapted to assess communication oftwo typically developing children of 1.6 years age in unscr...
