Consider a gambling game in which we are allowed to repeatedly bet a portion of our bankroll at favorable odds. We investigate the question of how to minimize the expected number of rounds needed to increase our bankroll to a given target amount. Specifically, we disprove a 50-year old conjecture of L. Breiman [1], that there exists a threshold strategy that optimizes the expected number of rou...

This paper discusses the feature checking mechanism of interrogative sentences in Japanese and Korean. We first focus on a phenomenon of omitting question markers in informal speech in Japanese and attempt to provide an account for it within the framework of Principles and Parameters approach. We argue that question markers can be omitted only if interrogative features of the sentence can be pr...

The paper reviews the development of the six-port measurement technique since the time it was introduced in 1977 until present days. Working principles of six-port reflectometer and six-port network analyzer are explained. The technique is put in context with other scattering parameter measurement principles; the advantages and drawbacks are discussed. Some typical SPR implementations are prese...

UNLABELLED This paper proposes approaches to break down the boundaries that reduce the ability of the health workforce to respond to population needs, or workforce flexibility. Accessible health services require sufficient numbers and types of skilled workers to meet population needs. However, there are several reasons that the health workforce cannot or does not meet population needs. These pr...

A fundamental goal in vision science is to determine how many neurons in how many areas are required to compute a coherent interpretation of the visual scene. Here I propose six principles of cortical dynamics of visual processing in the first 150 ms following the appearance of a visual stimulus. Fast synaptic communication between neurons depends on the driving neurons and the biophysical hist...

By their nature, data warehouses store large volumes of data. For analytical purposes, the final dataset is frequently aggregated and the transactional detail is lost. When users look at the analytical reports generated out of the BW system, the results they see can not be easily verified. As a result, creating user confidence in data quality becomes difficult and user trust is eroded, which ca...
