Over the last few decades, in disciplines as diverse as economics, geography and complex systems, a perspective has arisen proposing that many properties of cities are quantitatively predictable due to agglomeration or scaling effects. Using new harmonized definitions for functional urban areas, we examine to what extent these ideas apply to European cities. We show that while most large urban systems in Western Europe (France, Germany, Italy, Spain, UK)approximately agree with theoretical...

Snake robots are highly articulated mechanisms that can thread through tightly packed volumes and access locations that people and machinery otherwise cannot access. These devices come in many forms, including locomoting snakes whose internal undulations allow them to maneuver in difficult to negotiate terrains, as well as fixed-base elephant trunks or probes that can reach into cluttered spaces with minimal invasion. The proposed work focuses on the latter of these devices as they have many...

Ceramic armor provides unique opportunities to achieve lighter weight protection of tactical vehicles. However ceramics are much more sensitive to multi-impact damage than traditional metallic armors. Small ceramic tiles are generally used, and the intersecting locations of these tiles are well known to provide reduced protection relative to the center of a tile. For armor panel assembly, it is useful to know how the width of the intersection correlates with reduced performance. Experiments and...

In recent years, small-scale quantum information processors have been realized in multiple physical architectures. These systems provide a universal set of gates that allow one to implement any given unitary operation. The decomposition of a particular algorithm into a sequence of these available gates is not unique. Thus, the fidelity of the implementation of an algorithm can be increased by choosing an optimized decomposition into available gates. Here, we present a method to find such a...

Performing experiments on small-scale quantum computers is certainly a challenging endeavor. Many parameters need to be optimized to achieve high-fidelity operations. This can be done efficiently for operations acting on single qubits, as errors can be fully characterized. For multiqubit operations, though, this is no longer the case, as in the most general case, analyzing the effect of the operation on the system requires a full state tomography for which resources scale exponentially with the...

Lying at the intersection of public opinion, science, and partisan politics, the debate over climate change has grown with each successive president from Richard M. Nixon to Barack H. Obama. This article argues that these two presidents, from different parties, in different eras, and with different motivations, did the most to advance federal policy. Nixon's actions laid the foundation for Obama's activism, defining the realm of possible. In a similar sense, Obama has also set the parameters of...

Our hypothesis is that subjects who receive the SIS-ECM scaffold material will have significant new muscle growth and improvements in strength in the treated extremity. The proposed prospective, non-randomized, two-armed study in forty (40) subjects will establish the safety and effectiveness of a regenerative scaffold for the restoration of functional musculotendinous tissue, including the restoration of blood supply and innervation. Cohort 1 will include 20 subjects with upper extremity...

Sympathetic postganglionic neurons (SPNs) located in sympathetic ganglia represent the final common sympathetic motor output. Even though SCI produces a profound plasticity in sympathetic autonomic function, the extent that SCI-induced dysautonomia is based on SPN changes within the thoracic paravertebral sympathetic chain is unknown. Given their strategic site in autonomic signaling to body, any plasticity is likely to be of high significance, yet there is a paucity of studies undoubtedly due...

This paper is a discussion presented August 13, 1981 at the American Statistical Association Annual Meeting in Detroit of an invited paper by John Geweke entitled 'The Measurement of Linear Dependence and Feedback Between Multiple Time Series'. It shows how the results presented by Geweke can be derived and clarified using the approaches to multiple time series modeling published in Parzen (1967), (1969), (1977), and Parzen and Newton (1979).

The objective of the project is to enhance the long-term fit and performance of prosthetic sockets through smart sensing, adaptive interface, and shear-based dynamic fitting strategy. In the second year, the sensor development effort has been focused on 1) fabricating custom-made prosthetic liners with the sensors embedded and 2) developing a portable dynamic sensor interrogation unit. We have implemented a test fixture for sensor characterization and validated that the shear/pressure sensor...

The drift shells of protons in a model magnetic field are calculated. The observed radial gradient of the protons is combined with the calculated drift shells to predict the flux levels at several local times for different pitch angles and energies. A simplified method is used to describe the drift shells. The field model is a three term Mead model, which is fit to the observed B values at synchronous orbit. The resulting predicted local time dependent fluxes match the observed fluxes very well...

Military personnel are tasked with providing a clean, on-spec supply of jet fuel for a large variety of aircraft and ground powered vehicles. Occasionally, fuel filters become fouled and / or fuel samples appear contaminated with particles. Fuel handlers must make several decisions based on the apparent severity of the condition. In the majority of cases the only remediation necessary is filtration and water separation. However, if the contamination is the result of a failing valve, pump, other...

Aromatase inhibitors (AIs) cause muscle weakness, bone loss, and joint pain in up to half of cancer patients. Preclinical studies have demonstrated that increased osteoclastic bone resorption can impair muscle contractility and prime the bone microenvironment to accelerate metastatic growth. I hypothesized that AI-induced bone loss could increase breast cancer progression in bone and exacerbate muscle weakness associated with bone metastases. Female athymic nude mice underwent ovariectomy (OVX)...

We have determined that one monoclonal antibody cloned from the memory B cell population of the mother of a child with ASD binds Caspr2. This antibody disrupts fetal brain development and leads to an ASD-like phenotype in the offspring. Forty percent of women with brain-reactive serology and a child with ASD exhibit antibodies to Caspr2; thus this antibody may contribute to approximately 5 percent of cases of ASD.

The progression of prostate cancer (PCa) to castrate resistant metastatic disease is an ominous diagnosis. To overcome tumor cell heterogeneity based therapeutic resistance of PCa, the Isaacs/Denmeade laboratories have advocated the use of chemical engineering principles to modify potent killing toxins as molecular grenades, which are delivered systemically and selectively detonated; thereby, liberating their killing toxin efficiently only within the extracellular microenvironment at cancer...

The alternative non-homologous end-joining (NHEJ) machinery facilitates several genomic rearrangements, some of which can lead to cellular transformation. This error-prone repair pathway is triggered upon telomere de-protection to promote the formation of deleterious chromosome end-to-end fusions. We showed that Polq inhibition suppresses alternative NHEJ at dysfunctional telomeres, and hinders chromosomal translocations at non-telomeric loci. In addition, we found that loss of Polq results in...

The androgen receptor is a primary target of prostate cancer treatment and prevention. For metastatic prostate cancer (androgen responsive), androgen deprivation therapy (ADT) has been the standard mode of treatment. The tumors initially respond with the inhibition of growth, but most tumors invariably relapse leading to a lethal castration resistant prostate cancer (CRPC), indicating a shift in tumor responsiveness. The proliferating primary tumor recruits a variety of stromal cells in its...

Cells that are deficient in homologous recombination (HR) DNA repair, such as those lacking functional BRCA1 are highly sensitive to poly(ADP-ribose) polymerase (PARP) inhibitors. Ovarian cancer patients that harbored germ-line BRCA1mutations treated with PARP inhibitors exhibited meaningful responses in early phase clinical trials. However, emerging clinical trial data indicates that PARP inhibitor therapy may benefit only a subset of BRCA1mutation carriers. We hypothesized that a range of...

The proposed research is focused on restoration of hand motor and sensory functions by utilizing a direct electrical interface with residual peripheral nerves. The direct connection with the residual nerves will enable the patient to have intuitive control over and receive touch sensation from a prosthetic hand that are not provided by current forearm prostheses. The improvement in intuitive control and the providing of sensory feedback will allow patients to use highly articulate prosthetic...

Profound deficits in the domain of social communication are a hallmark of autism spectrum disorders (ASD). These difficulties in social communication can have devastating effects for both individuals with autism and their loved ones as they negatively impact the ability to form and maintain relationships (Baron-Cohen, 1988; Dawson and Bernier, 2007). Difficulty understanding others emotions is central to the social communicative difficulties in ASD. Research suggests deficits in emotion...

We propose to investigate the relationship between p38MAPK signaling, wound inflammatory response, wound healing and long-term scar formation using a burn model in the female red Duroc pig. We hypothesize that topical p38MAPK inhibition will attenuate the depth of the burn by preventing hair-follicle cell apoptosis, attenuate the inflammatory phase of wound healing, and decrease the granulation layer thickness. We propose this modification in the early inflammatory response will also reduce...

Omalizumab is currently the only FDA approved monoclonal anti-IgE therapy. We solved the IgE:omalizumab crystal structure to 2.54 . This structure elucidates the mechanism of omalizumab inhibition of IgE:FcRI and IgE:CD23 interactions, and explains omalizumabs selectivity for free circulating IgE. Surprisingly, the complex structure shares significant similarity with the disruptive IgE inhibitor E2_79, and provides mechanistic insight into the efficiency with which disruptive inhibitors are...

Information from animal models and population studies suggest that mammary tumor promotion in adult life is influenced by prior exposure to carcinogens in early life. The main purpose of this project is to investigate whether or not activation of the aromatic hydrocarbon receptor (AhR) induces CpG methylation at the BRCA-1 gene, and if this epigenetic event predisposes to development of triple-negative breast cancers (TNBC). Major findings: Preliminary data acquired through the support of this...
