Models for the development and function of germinal centers (GCs) have been so widely discussed in the original literature that they now appear in immunology textbooks. Unfortunately, many of the tenets of these models have not yet been subjected to adequate experimental scrutiny. Indeed, recent studies have called several of their principal assumptions into question. In addition, the term germ...

We prove that every quadratic plane differential system having an isochronous center commutes with a polynomial differential system.

Language resource centers allow researchers to reliably deposit their structured data together with associated meta data and run services operating on this deposited data. We are looking into possibilities to create long-term persistency of both the deposited data and the services operating on this data. Challenges, both technical and non-technical, that need to be solved are the need to replic...

Elder abuse forensic centers present a new model of multidisciplinary collaboration on elder abuse cases. The "clients" of a forensic center are Adult Protective Services (APS), law enforcement, and the Long-term Care Ombudsman. Centers take the basic multidisciplinary team model and add a geriatrician and a psychologist. Additionally, forensic center team members make home visits with APS and ...

Residential treatment centers (RTCs) usually house youths with significant psychiatric, psychological, behavioral, or substance abuse problems who have been unsuccessful in outpatient treatment or have proved too ill or unruly to be housed in foster care, day treatment programs, and other nonsecure environments but who do not yet merit commitment to a psychiatric hospital or secure correctional...

Trends in Internet infrastructure indicate that organizations with mission-critical needs are outsourcing applications to a small number of Internet data center providers. These providers operate networks and services at a global scale, and offer customers (and other service providers) a variety of services ranging from high bandwidth networking to fullfledged application hosting and IT managem...

We study a specific family of uniformly isochronous polynomial systems. Our results permit us to solve a problem about centers of such systems. We consider the composition conjecture for uniformly isochronous polynomial systems.

Pituitary tumors and associated neuroendocrine disorders pose significant challenges in diagnostic and therapeutic management. Optimal care of the "pituitary patient" is best provided in a multidisciplinary collaborative environment that includes not only experienced pituitary practitioners in neurosurgery and endocrinology, but also in otorhinolaryngological surgery, radiation oncology, medica...
