The let-7 microRNA (miRNA) regulates cell cycle exit and terminal differentiation in the C. elegans heterochronic gene pathway. Low expression of let-7 results in retarded vulva and hypodermal cell development in C. elegans and has been associated with several human cancers. Previously, the versatile scaffold protein receptor for activated C kinase 1 (RACK1) was proposed to facilitate recruitme...

We show that for every effective left conjugacy closed left quasigroup, there is an induced rack that retains the conjugation structure of the left translations. This means that cryptographic protocols relying on conjugacy search can be secure only if conjugacy search of left translations is infeasible in the induced rack. We note that, in fact, protocols based on conjugacy search could be simp...

We designed a variable-tilt microfuge fermentation rack to screen liquid cultures of wild and mutant yeasts for ethanol production. The rack design allows for the evaluation of up to 40 cultures in the space normally required for three 125 mL Erlenmeyer flasks. Microfuge tubes containing 1.0 mL of inoculated medium were placed in the rack and incubated with shaking. This technique gave reproduc...

Ackee canners often harvest mature fruits that are placed on sun racks to complete ripening (indicated by podopening). It is unknown whether the nutrient composition of rack-ripened fruits differs from those completely ripened on trees. This study compares proximate, mineral and fatty acid composition of raw, mature arils of tree-ripened and rackripened fruits. Proximate and mineral composition...

Pass, Jason M., Yuting Zheng, William B. Wead, Jun Zhang, Richard C. X. Li, Roberto Bolli, and Peipei Ping. PKCe activity induces dichotomous cardiac phenotypes and modulates PKCe-RACK interactions and RACK expression. Am J Physiol Heart Circ Physiol 280: H946–H955, 2001.—Receptors for activated C kinase (RACKs) have been shown to facilitate activation of protein kinase C (PKC). However, it is ...

In many data centers, server racks are highly underutilized. Rack slots are left empty to keep the sum of the server nameplate maximum power below the power provisioned to the rack, while the servers placed in the rack cannot make full use of available rack power. The root cause of this rack underutilization is that the server nameplate power is often much higher than can be reached in practice...

Virtual Data Center (VDC) embedding has drawn significant attention recently because of the growing need for efficient and flexible means (DC) resource allocation. Existing studies on VDC mainly focus improving DCs' utilization. However, an important problem that not been considered in solutions is creation hot spots by excessive heat dissipation air generation from racks DCs, which have advers...
