Florida Atlantic University is a public university located in Boca Raton, Florida, with five satellite campuses located in the Florida cities of Dania Beach, Davie, Fort Lauderdale, Jupiter, and in Fort Pierce at the Harbor Branch Oceanographic Institution. FAU belongs to the 12-campus State University System of Florida and serves South Florida, which has a population of more than five million people and spans more than 100 miles of coastline. Florida Atlantic University is classified by the Carnegie Foundation as a research university with high research activity. The university offers more than 180 undergraduate and graduate degree programs within its 10 colleges in addition to its sole professional degree from the College of Medicine. Programs of study span from arts and humanities, the science, medicine, nursing, accounting, business, education, public administration, social work, architecture, engineering, computer science, and more.Florida Atlantic opened in 1964 as the first public university in southeast Florida, offering only upper-division and graduate level courses. Although initial enrollment was only 867 students, this number increased in 1984 when the university admitted its first lower-division undergraduate students. As of 2012, enrollment has grown to over 30,000 students representing 140 countries, 50 states and the District of Columbia. Since its inception, Florida Atlantic has awarded more than 110,000 degrees to nearly 105,000 alumni worldwide.In recent years Florida Atlantic has undertaken an effort to increase its academic and research standings while also evolving into a more traditional university. The university has raised admissions standards, increased research funding, built new facilities, and established notable partnerships with major research institutions. The efforts have resulted in not only an increase in the university's academic profile, but also the elevation of the football team to Division I competition status, the on-campus stadium, more on-campus housing, and the establishment of its own College of Medicine in 2010.

We consider joint optimization for sensing-channel selection and ensuing power control problem with cognitive radios over time-varying fading channels. It is shown that this joint design can be judiciously formulated as a convex optimization problem. Optimal joint sensing-channel selection and power control scheme is then derived in closed-form under the constraints of average power budget and maximum allowable probability of collisions with the primary communications. In addition, we develop a stochastic optimization algorithm that can operate without a-priori knowledge of the fading channel statistics. It is rigourously established that the proposed stochastic scheme is capable of dynamically learning the intended wireless channels on-the-fly to approach the optimal strategy almost surely. Numerous results are also provided to evaluate the proposed schemes for cognitive transmissions over block fading channels. © 2011 IEEE.

Since the time of the Greeks, philosophers and scientists have wondered about the origins of structure and function. Plato proposed that the origins of structure and function lie in the organism's nature whereas Aristotle proposed that they lie in its nurture. This nature-nurture dichotomy and the emphasis on the origins question has had a powerful effect on our thinking about development right into modern times. Despite this, empirical findings from various branches of developmental science have made a compelling case that the nature-nurture dichotomy is biologically implausible and, thus, that a search for developmental origins must be replaced by research into developmental processes. This change in focus recognizes that development is an immensely complex, dynamic, embedded, interdependent, and probabilistic process and, therefore, renders simplistic questions such as whether a particular behavioral capacity is innate or acquired scientifically uninteresting. © International Society on Infant Studies (ISIS).

Spin-foam models are hoped to provide a dynamics for loop quantum gravity. These start from the Plebanski formulation of gravity, in which gravity is obtained from a topological field theory, BF theory, through constraints, which, however, select more than one gravitational sector, as well as an unphysical degenerate sector. We show this is why terms beyond the needed Feynman-prescribed one appear in the semiclassical limit of the EPRL spin-foam amplitude. By quantum mechanically isolating a single gravitational sector, we modify this amplitude, yielding a spin-foam amplitude for loop quantum gravity with the correct semiclassical limit. © 2013.

In general neutron stars in binaries are spinning. Recently, a new quasi-equilibrium approximation that includes a rotational velocity piece for each star has been proposed to describe binary neutron stars with arbitrary rotation states in quasicircular orbits. We have implemented this approximation numerically for the first time, to generate initial data for neutron star binaries with spin. If we choose the rotational velocity piece such that it equals the Newtonian rigid rotation law, we obtain stars with fluid 4-velocities that have expansion and shear of approximately zero, as one would expect for quasi-equilibrium configurations. We also use the new approach to construct and study initial data sequences for irrotational, corotating, and fixed rotation binaries. © 2012 American Physical Society.

Tissue inhibitors of metalloproteinases (TIMPs) are widely distributed in the animal kingdom and the human genome contains four paralogous genes encoding TIMPs 1 to 4. TIMPs were originally characterized as inhibitors of matrix metalloproteinases (MMPs), but their range of activities has now been found to be broader as it includes the inhibition of several of the disintegrin-metalloproteinases, ADAMs and ADAMTSs. TIMPs are therefore key regulators of the metalloproteinases that degrade the extracellular matrix and shed cell surface molecules. Structural studies of TIMP-MMP complexes have elucidated the inhibition mechanism of TIMPs and the multiple sites through which they interact with target enzymes, allowing the generation of TIMP variants that selectively inhibit different groups of metalloproteinases. Engineering such variants is complicated by the fact that TIMPs can undergo changes in molecular dynamics induced by their interactions with proteases. TIMPs also have biological activities that are independent of metalloproteinases; these include effects on cell growth and differentiation, cell migration, anti-angiogenesis, anti- and pro-apoptosis, and synaptic plasticity. Receptors responsible for some of these activities have been identified and their signaling pathways have been investigated. A series of studies using mice with specific TIMP gene deletions has illuminated the importance of these molecules in biology and pathology. © 2010 Elsevier B.V.
