    • p-Efficient Estimators 

      Papantoni-Kazakos, P. (1975-08-20)
      This paper is concerned with estimates of an unknown vector parameter S based on observations X. A generalized error autocorrelation matrix with components the error moments of order 2p, is defined. A lower bound for this matrix is found and the p-efficient P(X/S) statistics realizing it are determined. The cases of i) X and S real, ii) S scalar ...
    • P-Splines Using Derivative Information 

      Calderon, Christopher P.; Martinez, Josue G.; Carroll, Raymond J.; Sorensen, Danny C. (2009-04)
      Time series associated with single-molecule experiments and/or simulations contain a wealth of multiscale information about complex biochemical systems. However efficiently extracting and representing useful physical information from these time series measurements can be challenging. We demonstrate how Penalized splines (P-Splines) can be useful in ...
    • P-Type Silicon Strip Sensors for the new CMS Tracker at HL-LHC 

      Tracker Group of the CMS Collaboration; Akgün, B.; Ecklund, K.M.; Kilpatrick, M.; Nussbaum, T.; (2017)
      The upgrade of the LHC to the High-Luminosity LHC (HL-LHC) is expected to increase the LHC design luminosity by an order of magnitude. This will require silicon tracking detectors with a significantly higher radiation hardness. The CMS Tracker Collaboration has conducted an irradiation and measurement campaign to identify suitable silicon sensor ...
    • P.L.A.T.F.O.R.M. The Public of Lagos Agency of Trash Formation, Organization, Remediation, and Management 

      Lee, Brian (2012-09-05)
      Lagos, Nigeria is a city of rapidly shifting conditions and perpetual crises with issues of over population, pollution, limited circulation, waste management, density, poverty, and social disparity. These conditions have resulted in the proliferation of slum settlements along the coastal edges of the megacity. However, the radical conditions of Lagos ...
    • p62/SQSTM1 is required for cell survival of apoptosis-resistant bone metastatic prostate cancer cell lines 

      Chang, Megan A.; Morgado, Micaela; Warren, Curtis R.; Hinton, Cimona V.; Farach-Carson, Mary C.; (2014)
      BACKGROUND: Bone marrow stromal cell (BMSC) paracrine factor(s) can induce apoptosis in bone metastatic prostate cancer (PCa) cell lines. However, the PCa cells that escape BMSC-induced apoptosis can upregulate cytoprotective autophagy. METHODS: C4-2, C4-2B, MDA PCa 2a, MDA PCa 2b, VCaP, PC3, or DU145 PCa cell lines were grown in BMSC conditioned ...
    • Pacer: Taking the Guesswork Out of Live Migrations in Hybrid Cloud Computing 

      Zheng, Jie; Ng, T. S. Eugene; Sripanidkulchai, Kunwadee; Liu, Zhaolei (2013-10-01)
      Hybrid cloud computing, where private and public cloud resources are combined and applications can migrate freely, ushers in unprecedented flexibility for businesses. To unleash the benefits, commercial products already enable the live migration of full virtual machines (CPU, memory, disk, network) between distant cloud datacenters. Unfortunately, ...
    • Pacific Plate Apparent Polar Wander, Hot Spot Fixity, and True Polar Wander During the Formation of the Hawaiian Island and Seamount Chain From an Analysis of the Skewness of Magnetic Anomaly 20r (44ᅠMa) 

      Zheng, Lin; Gordon, Richard G.; Woodworth, Daniel (2018)
      While it is well documented that the Hawaiian hot spot has shifted southward relative to the spin axis since the formation of some of the Emperor seamounts, the paleolatitude of the hot spot during the formation of the Hawaiian chain is poorly known. To better determine the latter, here we estimate the location of the 44 Ma Pacific plate paleomagnetic ...
    • Pacific plate deformation from horizontal thermal contraction 

      The central approximation of plate tectonics is that the plates are rigid, which gives the theory its rigor and predictive power. Space geodetic measurements are consistent with the rigidity of stable plate interiors, but some failures of plate-circuit closure, in particular of oceanic plates, indicate that plates may be measurably non-rigid. We ...

      DIAS, DANIEL MANUEL (1981)
      Delta networks are a class of multistage interconnection networks that can be used to interconnect a large number of modules in a modular computing system. In a packet communication environment, the modules in a system communicate asynchronously using fixed size packets. In this environment, delta networks exhibit a large parallelism in packet transfer ...
    • Paid Family Leave: Balancing Acts 

      Beebe, Joyce; James A. Baker III Institute for Public Policy (2017)
    • Pain: Is it All in My Head? Rebecca Clearman MD, FAAFM&R, FACSM, FPASSOP 

      Clearman, Dr. Rebecca (2014)
      Dr. Clearman discusses the effect of stress on musicians' health.
    • Paintable Battery 

      Singh, Neelam; Galande, Charudatta; Miranda, Andrea; Mathkar, Akshay; Gao, Wei; (2012)
      If the components of a battery, including electrodes, separator, electrolyte and the current collectors can be designed as paints and applied sequentially to build a complete battery, on any arbitrary surface, it would have significant impact on the design, implementation and integration of energy storage devices. Here, we establish a paradigm change ...
    • Pair extended coupled cluster doubles 

      Henderson, Thomas M.; Bulik, Ireneusz W.; Scuseria, Gustavo E. (2015)
      The accurate and efficient description of strongly correlated systems remains an important challenge for computational methods. Doubly occupied configuration interaction (DOCI), in which all electrons are paired and no correlations which break these pairs are permitted, can in many cases provide an accurate account of strong correlations, albeit at ...
    • Pair invariant mass to isolate background in the search for the chiral magnetic effect in Au+Au collisions at √sNN=200 GeV 

      STAR Collaboration (2022)
      Quark interactions with topological gluon configurations can induce local chirality imbalance and parity violation in quantum chromodynamics, which can lead to the chiral magnetic effect (CME)—an electric charge separation along the strong magnetic field in relativistic heavy-ion collisions. The CME-sensitive azimuthal correlator observable (Δγ) is ...
    • Pairing and Phase Separation in a Polarized Fermi Gas 

      Partridge, Guthrie B.; Li, Wenhui; Kamar, Ramsey I.; Liao, Yean-an; Hulet, Randall G. (2006)
      We report the observation of pairing in a gas of atomic fermions with unequal numbers of two components. Beyond a critical polarization, the gas separates into a phase that is consistent with a superfluid paired core surrounded by a shell of normal unpaired fermions. The critical polarization diminishes with decreasing attractive interaction. For ...
    • Pairing correlations near a Kondo-destruction quantum critical point 

      Pixley, J.H.; Deng, Lili; Ingersent, Kevin; Si, Qimiao (2015)
      Motivated by the unconventional superconductivity observed in heavy-fermion metals, we investigate pairing susceptibilities near a continuous quantum phase transition of the Kondo-destruction type. We solve two-impurity Bose-Fermi Anderson models with Ising and Heisenberg forms of the interimpurity exchange interaction using continuous-time quantum ...
    • Pakistan: A nation held back by NTDs 

      Blum, Alexander J.; Majid, M. Farhan; Hotez, Peter J.; James A. Baker III Institute for Public Policy (2018)
