Using the Bethe ansatz we obtain in a determinant form the exact solution of the master equation for the conditional probabilities of the totally asymmetric exclusion process with particle-dependent hopping rates on Z. From this we derive a determinant expression for the timeintegrated current for a step-function initial state.

Diagnosis of central nervous system (CNS) involvement in neoplastic diseases is a major problem. Recent progresses in chemotherapies and targeted therapies have improved survival in cancer patients. In this context of better-controlled systemic disease, brain metastases (BM) are emerging as a new challenge for the oncologist1. BM are one of the most common neurologic complications of cancer. Th...
Climatically driven Moran effects have often been invoked as the most likely cause of regionally synchronized outbreaks of insect herbivores without identifying the exact mechanism. However, the degree of match between host plant and larval phenology is crucial for the growth and survival of many spring-feeding pest insects, suggesting that a phenological match/mismatch-driven Moran effect may ...
BACKGROUND Lumbar facet nerve (medial branch) blocks are often used to diagnose facet joint-mediated pain. The authors recently described a new ultrasound-guided methodology. The current study determines its accuracy using computed tomography scan controls. METHODS Fifty bilateral ultrasound-guided approaches to the lumbar facet nerves were performed in five embalmed cadavers. The target poin...
