Adding examples of the majority class to the training set can have a detrimental eeect on the learner's behavior: noisy or otherwise unreliable examples from the majority class can overwhelm the minority class. The paper discusses criteria to evaluate the utility of clas-siiers induced from such imbalanced training sets, gives explanation of the poor behavior of some learners under these circum...

Guinea pigs were inoculated with the Vallée O type strain of the virus of foot-and-mouth disease. 42 to 48 hours after inoculation red blood cells washed in saline were found to be infective for normal guinea pigs suggesting that erythrocytes carry virus entities at the height of generalization of the disease. This infection is no longer obtained at 92 hours after inoculation when general sympt...

In this work we carry out an exhaustive study to find quark mass matrices in the Standard Model~(SM), with maximum number of texture zeros consistent experimental data. We found four viable configurations five that adjust masses, mixing angles and CP violation phase, deviations below $1\sigma$ level respect current SM best fit values. One most important aspects is economic procedure zeros: reso...

Abstract -This paper presents an architecture for a high-speed carry select adder with very long bit lengths utilizing a conflict-free bypass scheme. The proposed scheme has almost half the number of transistors and is faster than a conventional carry select adder. A comparative study is also made between the proposed adder and a Manchester carry chain adder which shows that the proposed scheme...

Most approaches to the ramiication problem are based on the principle of minimization of change. It turns out, however, that this principle can not be applied uniformly, and many modern approaches use a clas-siication of the uents whereby change is only minimized in some of the uents. The present article reviews these approaches and their underlying motivations. It also presents a uniied formal...
