Abstract A proven method to enhance the mechanical properties of additively manufactured plastic parts is embedding continuous fibers. Due its great flexibility, fiber-reinforced material extrusion allows fiber strands be deposited along optimized paths. Nevertheless, fibers have so far been embedded in contour-based or on basis regular patterns. The outstanding strength and stiffness longitudi...

Training a shape prior has been potent scheme for anatomical object segmentations, especially for images with noisy or weak intensity patterns. When the shape representation lives in a high dimensional space, principal component analysis is often used to calculate a low dimensional variation subspace from frequently limited number of training samples. However, the eigenmodes of the subspace ten...

The interplay of environmental and genetic factors in the developmental organization of the hippocampus has not been fully elucidated. The neuropeptide corticotropin-releasing factor (CRF) is released from hippocampal interneurons by environmental signals, including stress, to increase synaptic efficacy. In the early postnatal hippocampus, we have previously characterized a transient population...

the effect of drought on the seed yield and some associated characteristics of common been under normal and drought stress conditions and determination of durable genotypes to drought were studied by planting 32 genotypes in two separate augmented designs in normal and stress conditions. these genotypes were evaluated in randomized complete block design with 3 replications in the field of facul...

The primary function of lens is to focus images perfectly on the retina. Lens crystallins however are flexible nanomachines that frequently accomplish their biological function by collective atomic motions in and/or out the lens. Although genetic and biochemical data on the βB2-crystallin protein are available from several sources, the correlation between conformational changes and dynamic beha...

Because of its appealing simplicity, the elastic network model (ENM) has been widely accepted and applied to study many molecular motion problems, such as the molecular mechanisms of chaperonin GroEL-GroES function, allosteric changes in hemoglobin, ribosome motions, motor-protein motions, and conformational changes in general. In this dissertation, the ENM is employed to study various protein ...

In this paper an algorithm for large strain elasto-plasticity with isotropic hyperelasticity based on the multiplicative decomposition is formulated. The algorithm includes a (possible) constitutive equation for the plastic spin and mixed hardening in which the principal stress and principal backstress directions are not necessarily preserved. It is shown that if the principal trial stress dire...

We develop a procedure for the integration of balance equations in terms displacements orthotropic bodies with certain restrictions imposed on elastic moduli material. The components vector are expressed two functions, one which satisfies equation second order, while fourth-order equation. An algorithm is proposed solving boundary-value problems an rectangular prism. based separation principal ...
