In this paper the effect of imbalances between the two branches in LINC transmitters has been analyzed. Then these imbalances have been compensated in the proposed structure adaptively. Conjugate gradient algorithm has been used in the proposed structure to find optimum gain value of each branch for calibrating imbalances. These complex values changes automatically in a way to minimize ph...
LINC complexes, consisting of inner nuclear membrane SUN proteins and outer nuclear membrane KASH proteins, connect the nucleus to the cytoskeleton, transmitting forces that control the nucleus's position within the cell. But how LINC complexes affect the cytoskeleton, and thus the balance of forces across cells and tissues, is less well understood. Stewart et al. now demonstrate that the LINC ...
Abstract: The efficiency and linearity of power amplifiers based on the LINC technique are discussed. The use of resistive combiners as well as lossless Chireix combiners are detailed and their impact on amplifier linearity and efficiency are highlighted. The tradeoffs between linearity and efficiency in Chireix combiners are investigated experimentally and optimal choice of Chireix combiners i...

The 1963 LINC (Laboratory INstrument Computer) stands at the center of two stories: the computerization of the biologist's laboratory and the advent of small-scale computing. The brainchild of Wesley Clark, 'the most brilliant computer designer of his generation', LINC was developed specifically to address the failure of biologists to adopt computer technology. To meet their unique needs, Clark...
Two simple calibration schemes for the correction of the path imbalance in a linear amplification with nonlinear components (LINC) transmitter have been demonstrated. In the foreground algorithm, a baseband digital signal processor (DSP) evaluates the gain and phase imbalance with a set of calibration signals, while in the background algorithm, the imbalance is characterized by exchanging the t...
Many studies are uncovering functional roles for long noncoding RNAs (lncRNAs), yet few have been tested for in vivo relevance through genetic ablation in animal models. To investigate the functional relevance of lncRNAs in various physiological conditions, we have developed a collection of 18 lncRNA knockout strains in which the locus is maintained transcriptionally active. Initial characteriz...
Appropriate tissue morphogenesis strictly requires the developmental regulation of different types of nuclear movements. LINC (linker of nucleoskeleton and cytoskeleton) complexes are macromolecular scaffolds that span the nuclear envelope and physically connect the nuclear interior to different cytoskeletal elements and molecular motors, thereby playing essential roles in nucleokinesis. Recent...
Hauling and anchoring the nucleus within immobile or motile cells, tissues, and/or syncytia represents a major challenge. In the past 15 years, Linkers of the Nucleoskeleton to the Cytoskeleton (LINC complexes) have emerged as evolutionary-conserved molecular devices that span the nuclear envelope and provide interacting interfaces for cytoskeletal networks and molecular motors to the nuclear e...
L INC complexes do not maintain the space between nuclear membranes, except in cells exposed to mechanical stress, Cain et al. reveal. SUN proteins in the inner nuclear membrane and KASH proteins in the outer nuclear membrane form LINC complexes that regulate multiple processes by connecting the nucleoskeleton to the cytoskeleton. LINC complexes are also thought to maintain a uniform gap of ~50...
