Depending on temperature, the modified Hodgkin-Huxley (MHH) equations exhibit a variety of dynamical behaviors, including intrinsic chaotic firing. We analyze synchronization in a large ensemble of MHH neurons that are interconnected with gap junctions. By evaluating tangential Lyapunov exponents we clarify whether the synchronous state of neurons is chaotic or periodic. Then, we evaluate trans...

With increasing on-chip hardware, concurrency is a way to bridge the gap between the computational power demanded by the applications and that afforded by the computer platforms. Although parallel systems are increasingly popular, they remain very difficult to program. In fact, most compilers require the programmer to specify how to partition data or map program code to the system’s processors....

Program errors are hard to find because of the cause-effect gap between the time when an error occurs and the time when the error becomes apparent to the programmer. Although debugging techniques such as conditional and data breakpoints help to find error causes in simple cases, they fail to effectively bridge the cause-effect gap in many situations. Query-based debuggers offer programmers an e...

Program analysis tackles the problem of predicting the behavior or certain properties of the considered program code. The challenge lies in determining the dynamic run-time behavior statically at compile time. While in rare cases it is possible to determine exact dynamic properties already statically, in many cases, e.g., in analyzing memory dependencies, one can only find imprecise information...

Structural changes in the Korean population, such as a growing trend toward nuclear families and urbanization, have given rise to a generational gap between older adults and the younger generation. The current study developed a 6-week intergenerational program to facilitate interactions between nursing home residents and high school students. The effects of the program were examined in 120 part...

Much of the research analyzing immigrant participation in welfare programs investigates the extent to which immigrants enroll in cash benefit programs, with little attention being paid to the trends and determinants of immigrant participation in other programs. This paper uses data drawn from the decennial Censuses, the Survey of Income and Program Participation, and the Current Population Surv...

The performance gap for high performance applications has been widening over time. High level program transformations are critical to improve applications’ performance, many of which concern the determination of optimal values for transformation parameters, such as loop unrolling and blocking. Static approaches achieve these values based on analytical models that are hard to achieve because of ...

A significant gap remains between rural and urban students in the rate of admission to senior high school. One reason for this gap may be the high levels of tuition and fees for senior high school. By reducing student expectations of attending high school, high tuition and fees can reduce student academic performance in junior high school. In this paper we evaluate the impact of a senior high t...

Background The increasing burden of chronic kidney disease (CKD) underpins the importance for improved early detection and management programs in primary care to delay disease progression and reduce mortality rates. eMAP:CKD is a pilot program for primary care aimed at addressing the gap between current and best practice care for CKD. Methods Customized software programs were developed to int...
