the ultrasonic measurement of the fetal femur length is a sensitive and precise variable for estimation of fetal growth and development. tlte objective of this study was to predict gestational age in fetuses older ttian twenty-four weeks of gestation by ultrasonic measurement of the femur length. in this study, pregnant mothers were identified by the criteria of normality, such as well-known lm...

a pot experiment laid out in factorial arranged in completely randomized design with three replications was implemented to evaluate the effects of seed priming in ameliorating salinity stress in sesame (sesamum indicam l.) during seedling development and the early vegetative growth. factors included five priming treatments : control (non priming) , hydropriming, halopriming with nacl, kcl , cac...

the development of seminal and lateral root system plays a major role in plant access to water and nutrients under abiotic stress, especially salinity. in order to understand the relation between root growth responsesand shoot physiological indices oftwo bread wheat cultivars contrasting in salt tolerance (kavir and shiraz), a greenhouse experiment was conducted with two salinity levels (0 and ...

Telomeres are specialized nucleoprotein caps that protect chromosome ends assuring cell division. Single-cell telomere quantification in animals established a critical role for telomerase in stem cells, yet, in plants, telomere-length quantification has been reported only at the organ level. Here, a quantitative analysis of telomere length of single cells in Arabidopsis root apex uncovered a he...

It is known that total telomere length is shorter in invasive breast cancer than in normal breast tissue but the status of individual telomere lengths has not been studied. Part of the difficulty is that usually telomere length in interphase cells is measured on all chromosomes together. In this study we compared normal breast epithelium, duct carcinoma in situ (DCIS), and invasive duct carcino...

This paper studies variable-length coding with noiseless feedback for discrete memoryless channels. Yamamoto and Itoh’s two-phase scheme achieves the optimal error-exponent, but due to the block-coding nature it is not optimal in the expansion of the message size logM . Polyanskiy et al. showed that with feedback, the back-off from capacity is logarithmic in the expected latency l. The O(log l)...

We present a test resource partitioning (TRP) technique that simultaneously reduces test data volume, test application time, and scan power. The proposed approach is based on the use of alternating run-length codes for test data compression. We present a formal analysis of the amount of data compression obtained using alternating run-length codes. We show that a careful mapping of the don’t-car...
