We develop a model of ̄rm size in which ̄rms are unable to access as many consumers as they want. Newly arrived consumers match randomly with ̄rms. Subsequently, consumers must pay search costs to be able to switch ̄rms. This cost promotes an inertial tendency for consumers to remain with the ̄rm they currently buy from. Consequently, established ̄rms enjoy a proprietary relationship with respe...

Rhabdomyosarcoma (RMS) is the most common pediatric soft tissue sarcoma with poor prognosis. The genetic etiology of RMS remains largely unclear underlying its development and progression. To reveal novel genes more precisely and new therapeutic targets associated with RMS, we used high-resolution array comparative genomic hybridization (aCGH) to explore tumor-associated copy number variations ...

Evidence has accumulated that sex hormones play an important role in several types of cancer. Because they are also involved in skeletal muscle development and regeneration, we were therefore interested in their potential involvement in the pathogenesis of human rhabdomyosarcoma (RMS), a skeletal muscle tumor. In the present study, we employed eight RMS cell lines (three fusion positive and fiv...

BACKGROUND Precise measurement of the QT interval is often hampered by difficulty determining the end of the low amplitude T wave. Root mean square electrocardiography (RMS ECG) provides a novel alternative measure of ventricular repolarization. Experimental data have shown that the interval between the RMS ECG QRS and T wave peaks (RTPK) closely reflects the mean ventricular action potential d...

Thyroid sarcoma is a very rare entity, accounting for less than 1% of all malignant thyroid tumours. Rhabdomyosarcoma (RMS) is a sarcoma subtype, which is more common in children and adolescents. In this case, a 68-year old man, presented with hoarseness and diagnosed with pleomorphic RMS, was explored. No study of primary thyroid pure RMS has been reported in the literature, with the exception...

The O-Ring theory is used to analyze the emergence of ̄rms organized as partnerships. The owner-managers of such entrepreneurial ̄rms bene ̄t from ability matching within their production teams. However, they must bear the project risk. Risk-aversion then induces a second-best solution. Integrated ̄rms managed on behalf of riskneutral residual-claimants face information and/or enforcement problem...
