Efficient solution of the single source shortest path (SSSP) problem on road networks is an important requirement for numerous real-world applications. This paper introduces an algorithm for the SSSP problem using compression method. Owning to precomputing and storing all-pairs shortest path (APSP), the process of solving SSSP problem is a simple lookup of(More)
This paper establishes a framework for an analytical theory of short-run macroeconomic cycles with intersectoral migration of agricultural labor in a developing economy. It defines measurements for the migration and finds cyclical fluctuations in farmer migrations. Data show such fluctuations are much more important in some developing economy than(More)
In this paper, we present a statistical parametric speech synthesis system based on the polynomial segment model (PSM). As one of the segmental models for speech signals, PSM explicitly describes the trajectory of the features in a speech segment, and keeps the internal dynamics of the segment. In this work, spectral and excitation parameters are modeled by(More)
The current success of targeted inhibition against cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) and Programmed Death 1/Programmed Death Ligand 1 (PD-1/PD-L1, herein collectively referred to as PD) pathways is hailed as a cancer immunotherapy breakthrough. PD-L1, known also as B7 homolog 1 (B7-H1), was initially discovered by Dr. Lieping Chen in(More)
Nowadays the trackside equipment layout of the traditional urban rail transit signal system mainly depends on the personal experience of the system designer. The accuracy and efficiency of the work cannot be guaranteed, relying more on the field test in the future. This paper focuses on this problem existing in the design work of signal system, based on the(More)
The central nervous system (CNS) is an immune-privileged organ with the capacity to prevent excessive inflammation. Aside from the blood-brain barrier, active immunosuppressive mechanisms remain largely unknown. We report that a neuron-specific molecule, synaptic adhesion-like molecule 5 (SALM5), is a crucial contributor to CNS immune privilege. We found(More)
Acknowledgments This is not simply a dissertation, but also a record of the most important journey in my life. My sincere gratitude goes to all the great people who supported me along this amazing process to complete my doctoral studies in Economics. I wish to express enormous thanks to my main advisor Professor Robert Margo. His excellent guidance and(More)
