A Combined Trip Generation, Trip Distribution, Modal Split, and Trip Assignment Model
The traditional four-step model has been widely used in travel demand forecasting by considering trip generation, trip distribution, modal split and traffic assignment sequentially in a fixed order. However, this sequential approach suffers from the inconsistency among the level-of-service and flow values in each step of the procedure. In the last two decades, this problem has been addressed by...
متن کاملDeath takes a holiday
control may kick in even before a kinetochore is assembled. The mitotic checkpoint— controlled by Mad1, Mad2, Bub1, BubR1, and Bub3— delays anaphase by inhibiting APC until all kinetochores are properly attached to the spindle. Because inhibition of Mad2 leads to an accelerated mitosis and a precocious anaphase, it has been assumed that the checkpoint itself also regulates mitotic timing. But M...
متن کاملMycoplasma takes a walk.
T he mechanism of movement of individual cells shows extensive diversity. In the Eukarya, ATP is the driving force for cell motility (1). In contrast, in the Bacteria and Archaea, the chemiosmotic pathway of energy transduction powers flagellar rotation. Depending on the species, either hydrogen or sodium ion flux results in cell movement. ATP does not directly participate in providing the ener...
متن کاملSplicing takes a NAP
plicing factors, usually associated with RNA polymerase II transcripts, have a temporary home near sites of RNA polymerase I transcription, as shown on page 51 by Bubulya et al. During interphase, premRNA splicing factors such as the serine arginine–rich (SR) proteins reside in nuclear speckles, along with other pre-mRNA processing proteins. The speckles disassemble during mitosis, and then ref...
متن کاملIt takes a village.
Iknow what you’re thinking—“it takes a village” is a hackneyed phrase, and what is it doing in P&T? Perhaps you missed a critically important report from the Institute of Medicine (IOM) last winter on an approach for preventing and controlling hypertension.1 It certainly appears that it does take a village to manage high blood pressure in the U.S. As our readers probably know, nearly 73 million...
