    On June 23, 2005, the United States Supreme Court issued its ruling in the now infamous case of Kelo v. City of New London.\u27 In its first major ruling on eminent domain since 1984, the Court decided whether a city\u27s exercise of its eminent domain power to transfer property to private developers complied with the public use requirement of the Fifth Amendment

    Kinematics and control algorithm development and simulation for a redundant two-arm robotic manipulator system

    Get PDF
    An efficient approach to cartesian motion and force control of a 7 degree of freedom (DOF) manipulator is presented. It is based on extending the active stiffness controller to the 7 DOF case in general and use of an efficient version of the gradient projection technique for solving the inverse kinematics problem. Cooperative control is achieved through appropriate configuration of individual manipulator controllers. In addition, other aspects of trajectory generation using standard techniques are integrated into the controller. The method is then applied to a specific manipulator of interest (Robotics Research T-710). Simulation of the kinematics, dynamics, and control are provided in the context of several scenarios: one pertaining to a noncontact pick and place operation; one relating to contour following where contact is made between the manipulator and environment; and one pertaining to cooperative control

    Prevalence and Social Inequality in Youth Loneliness in the UK.

    Using data from the English arm of the Health Behaviour in School-aged Children (HBSC) study, we examined the prevalence of loneliness for school-aged adolescents and how it is linked to social inequalities. The HBSC study collects data from 11-, 13-, and 15-year-olds, and is repeated every four years, allowing the exploration of prevalence rates of loneliness pre COVID-19 pandemic for comparison. We also explored whether loneliness was associated with socio-economic status (SES) and linked to academic attainment and health complaints. The total sample was 14,077 from 156 schools in England. Findings revealed a stable prevalence rate of 8.2% for loneliness from 2006 to 2014. We also found, across all survey years, (1) those aged 15 years were significantly lonelier than younger peers, (2) those who reported lower SES were lonelier than their more well-off peers, and (3) higher loneliness was associated with being '"below average" academically and reporting more health complaints. Conclusions: These prevalence data enable researchers, policymakers, and others to make comparisons with prevalence rates during the COVID-19 pandemic to explore whether there have been increases in loneliness among school-aged adolescents. Loneliness was consistently related to social inequalities, suggesting that targeted interventions that include whole systems changes are needed

    DichroMatch: a website for similarity searching of circular dichroism spectra

    Get PDF
    Circular dichroism (CD) spectroscopy is a widely used method for examining the structure, folding and conformational changes of proteins. A new online CD analysis server (DichroMatch) has been developed for identifying proteins with similar spectral characteristics by detecting possible structurally and functionally related proteins and homologues. DichroMatch includes six different methods for determining the spectral nearest neighbours to a query protein spectrum and provides metrics of how similar these spectra are and, if corresponding crystal structures are available for the closest matched proteins, information on their secondary structures and fold classifications. By default, DichroMatch uses all the entries in the Protein Circular Dichroism Data Bank (PCDDB) for its comparison set, providing the broadest range of publicly available protein spectra to match with the unknown protein. Alternatively, users can download or create their own specialized data sets, thereby enabling comparisons between the structures of related proteins such as wild-type versus mutants or homologues or a series of spectra of the same protein under different conditions. The DichroMatch server is freely available at http://dichromatch.cryst.bbk.ac.uk

    Identification of the major cytoplasmic regions of the Neurospora crassa plasma membrane H (+)-ATPase using protein chemical techniques.

    The transmembrane topography of the Neurospora crassa plasma membrane H(+)-ATPase has been investigated using purified, reconstituted components and direct protein chemical techniques. Reconstituted proteoliposomes containing H(+)-ATPase molecules oriented predominantly with their cytoplasmic surface facing outward were treated with trypsin to liberate peptides present on the cytoplasmic surface of the H(+)-ATPase as recently described (Hennessey, J.P., Jr., and Scarborough, G. (1990) J. Biol. Chem. 265, 532-537. The released peptides were then separated from the proteoliposomes by gel filtration chromatography and further purified by high performance liquid chromatography. Fourteen such peptides were identified by NH2-terminal amino acid sequence analysis, directly defining these parts of the molecule as present on the cytoplasmic surface of the membrane. Moreover, this information identified several additional flanking stretches as likely to be cytoplasmically located by virtue of the fact that they are too short to cross the membrane and return. These results and the results of other recent experiments establish 417 residues of the 919 present in the ATPase molecule, at positions 2-100, 186-256, 441-663, and 897-920, as cytoplasmically located. Taken together with the results of our preliminary investigations of the membrane embedded sectors of the ATPase, this information allows the formulation of a reasonably detailed model for the transmembrane topography of the ATPase polypeptide chain
