Logging while drilling (LWD) is a drilling technique which obtains and transmits the logging data during oil/gas drilling operations. Because of the limited available transmission bandwidth of mud channel, how to improve the bandwidth utilization becomes a critical problem in LWD research. In this paper, by discussing the information entropy of real logging data, we find that the original encod...

Léri-Weill dyschondrosteosis (LWD) and Langer mesomelic dysplasia (LMD) are caused by mutations in the SHOX gene. LWD results from haploinsufficiency and is dominantly inherited, while the more severe LMD results from the homozygous loss of SHOX. We describe a family and fetus with two SHOX mutations. Several relatives carry an approximately 200 kb interstitial deletion that includes the whole ...

Mutations or deletions of the SHOX gene, located in the PAR1 region, are involved in idiopathic growth retardation. The SHOX gene escapes X inactivation in females. The growth failure of Turner Syndrome (X0) females is most likely the result of the presence of only one SHOX gene copy in each diploid cell (haploinsufficiency). The tall stature observed in Klinefelter (XXY) syndrome and in Triple...

Large woody debris (LWD) was added as an experimental stream restoration technique in two streams in southwest Virginia. Additions were designed to compare human judgement in log placements against a randomized design and an unmanipulated reach, &d also to compare effectiveness in a lowand a high-gradient stream. Pool area increased 146% in the systematic placement and 32% in the random placeme...

Just as there was a close connection between hypothesis testing with the one-sample t-test and a confidence interval for the mean of a sample, there is a close connection between hypothesis testing and confidence intervals for the parameters of a linear model. We’ll start by explaining the confidence interval as the fundamental idea, and see how this leads to hypothesis tests. ellipse() from th...

This paper presents an analysis of the representation of instantaneous frequency using time-frequency distributions of energy density domain. Similarity to the ”ideal” instantaneous frequency presentation is chosen as a criterion for comparison of various distributions. Although all the commonly used distributions suffer from the artifacts along frequency axis, it is shown that the Wigner distr...

A male patient is reported with a 45,X karyotype and Leri-Weill dyschondrosteosis (LWD). FISH analysis with SHOX and SRY gene probes was carried out. One copy of both SHOX and SRY was detected in interphase nuclei, clarifying the origin of LWD and the male phenotype. Molecular results suggested that the 45,X karyotype arose through two independent events. The first occurred at paternal meiosis ...

Large Woody Debris (LWD) accumulation serves essential ecological functions and benefits society’s coastal ecosystems (e.g., beaches). Thus far, the ecosystem services perspective has paid little attention to LWD. Therefore, we aim contrast social perceptions on LWD its significance in Puerto Velero beach, Caribbean, Colombia. In consequence, contribution of conformation creation beach was anal...
