[Concentrations of radioactive cesium in different cuts of beef].
After the Fukushima No. 1 Nuclear Power Plant accident, high levels of radioactive cesium were detected in beef. Many prefectural governments decided to conduct blanket tests on meat from local beef cattle to prevent distribution of beef contaminated with radioactive cesium exceeding the provisional regulation value. In some cases, different concentrations of radioactive cesium were found in di...
متن کاملCake-Cutting with Different Entitlements: How Many Cuts are Needed?
A cake has to be divided fairly among n agents. When all agents have equal entitlements, it is known that such a division can be implemented with n − 1 cuts. When agents may have different entitlements, we show that at least 2n − 2 cuts may be necessary, and 2n · Θ(log(n)) cuts are always sufficient.
متن کاملOn the relative strength of different generalizations of split cuts
Split cuts are among the most important and well-understood cuts for general mixed-integer programs. In this paper we consider some recent generalizations of split cuts and compare their relative strength. More precisely, we compare the elementary closures of split, cross, crooked cross and general multi-branch split cuts as well as cuts obtained from multi-row and basic relaxations. We present...
متن کاملType Two Cuts, Bad Cuts and Very Bad Cuts
Type two cuts, bad cuts and very bad cuts are introduced in [KL] for studying the relationship between Loeb measure and U-topology of a hyper nite time line in an !1-saturated nonstandard universe. The questions concerning the existence of those cuts are asked there. In this paper we answer, fully or partially, some of those questions by showing that: (1) type-two cuts exist, (2) the @1-isomorp...
