The aim of this study was to evaluate the effects of diets with different starch concentrations and fish oil (FO) supplementation on lactation performance, in vivo total-tract nutrient digestibility, N balance, and methane (CH4) emissions in lactating dairy cows. The experiment was conducted as a 4×4 Latin square design with a 2×2 factorial arrangement: 2 concentrations of dietary starch [low v...

Background Before launching a new bespoke foot orthotic (FO) product, it is necessary to understand how it works under compressive loads. Additive manufacturing and the selective laser sintering process in particular can enable a number of innovative and functional features to be integrated to the FO device. A simple example of this design freedom is to adjust the shell thickness of an FO. This...

Changes in follicular and luteal structures were assessed and concentrations of estradiol and progesterone were measured in 13 Hereford X Angus suckled beef cows during resumption of estrous cycles. Transrectal ultrasonography was used to monitor follicular size, ovulation, and formation and regression of the corpus luteum (CL). The interval from parturition to first postpartum ovulation (FO) w...

ON T H E HUSTINGS—Three Rice students prepare a mailing fo r the Professors fo r Johnson-Humphrey-Yarborough (see p. 6). Elsewhere, a national group, "Scientists and Engineers fo r Johnson-Humphrey" will fo rm a local chapter this Monday a t 8 pm a t the Houston Theatre Center. Rice president K. S. Pitzer, TSU President Nabr i t and hear t surgeon Michael DeBakey were among the founders of the ...

We consider the problem of deciding, given an instance query A(x), an EL-TBox T , and possibly an ABox signature Σ, whether A(x) is FO-rewritable relative to T and Σ-ABoxes. Our main results are PSPACE-completeness for the case where Σ comprises all symbols and EXPTIME-completeness for the general case. We also show that the problem is in PTIME for classical TBoxes and that every instance query...

This paper develops a fractional-order sliding mode based extremum seeking controller (FO SM-ESC) for the optimization of nonlinear systems. The proposed FO SM-ESC, involving an FO derivative function 0D q t sgn(e), 0 ≤ q < 1 is shown to achieve faster tracking and higher control accuracy than the integerorder (IO) SM-ESC. The tradeoff between control performance and parameters selection is ana...

The fundamental frequency (FO) of speech has been used for examining both transient emotional states [D. A. Vakoch, 1. Acoust. Soc. Am. 95, 2974 (1994)] and more stable personality traits. For example, low perceived pitch has been associated with attributions of high emotional stability [K. R. Scherer, Eur. J. Soc. Psycho!. 8, 467-487 (1978)]. In the current study, characteristics derived from ...

One of the most advanced approaches to querying data in the presence of ontologies is to make use of relational database systems, rewriting the original query and the ontology into a new query that is formulated in SQL or, equivalently, in firstorder logic (FO). For ontologies written in many standard description logics (DLs), however, such FO-rewritings are not guaranteed to exist. We study FO...
