451 Gondolo, PaoloHalo independent comparison of direct dark matter detection dataWe extend the halo-independent method of Fox, Liu, and Weiner to include energy resolution and efficiency with arbitrary energy dependence, making it more suitable for experiments to use in pre-senting their results. Then we compare measurements and upper limits on the direct detection of low mass (...2012-01-01
452 Miller, Jan D.High resolution X-ray microtomography based micro finite element analysis of mechanical properties of cellular materialThe macroscopic mechanical (elastic) properties of closed foams (ROHACELL) estimated from micro finite element analysis are reported in this paper.

453 Regehr, JohnHierarchical schedulers, performance guarantees, and resource managementAn attractive approach to scheduling applications with diverse CPU scheduling requirements is to use different schedulers for different applications. For example: real-time schedulers allow applications to perform computations before deadlines, time-sharing schedulers provide high throughput for com...1999-01-01
454 Mitchell, Joyce A.International efforts in nanoinformatics research applied to nanomedicineBackground: Nanomedicine and nanoinformatics are novel disciplines facing substantial challenges.

456 Scarpulla, MichaelInvestigation of combinatorial coevaporated thin film Cu 2ZnSnS4 (II): Beneficial cation arrangement in Cu-rich growthCu2ZnSn(S,Se)4 (CZTSSe) is an earth-abundant semiconductor with potential for economical photovoltaic power generation at terawatt scales. In this work, we use Raman scattering to investigate phase coexistence in combinatorial CZTS thin films grown at 325 or 470 C. The surface of the samples grown a...2014-01-01
457 Minteer, Shelley D.Investigating the reversible inhibition model of laccase by hydrogen peroxide for bioelectrocatalytic applicationsThe reversible inhibition of laccase by H2O2 as a bioelectrocatalyst was studied in mediated- and direct electron transfer-based configurations to understand the differences in mechanism. The reversible inhibition of laccase follows a noncompetitive inhibition model when 2,2-azino-bis(3-ethylbenzoth...2014-01-01
458 Liu, FengInterplay between quantum size effect and strain effect on growth of nanoscale metal thin filmsWe develop a theoretical framework to investigate the interplay between the quantum size effect (QSE) and strain effect on the stability of metal nanofilms. The QSE and strain effect are shown to be coupled through the concept of quantum electronic stress. First-principles calculations reveal large ...2012-01-01
459 Couldwell, William T.Intracranial hypotension as a complication of lumbar puncture prior to elective aneurysm clippingBackground: Lumbar dural defects are an uncommon but important cause of persistent intracranial hypotension in the neurosurgical population. We present a case of intracranial hypotension after elective craniotomy due to a lumbar puncture performed 3 weeks earlier. Case Description: A 55‑year‑old...2014-01-01
460 Couldwell, William T.Intracranial hypotension in the setting of concurrent perineural cyst rupture and subarachnoid hemorrhageAlthough most patients with intracranial hypotension typically present with headaches, the rest of the clinical spectrum is characteristically non-specific and often quite variable. In a patient with concurrent pathologies that can produce a similar clinical picture, a high index of suspicion must b...2013-01-01
461 Couldwell, William T.Intraoperative aneurysmal subarachnoid hemorrhage after rupture of a previously undiagnosed intracranial aneurysm during Chiari decompression: case report and literature reviewType 1 Chiari malformation occurs when caudal displacement of cerebellar tonsils below the level of foramen magnum obstructs the normal flow of cerebrospinal fluid (CSF) between the cranial and spinal spaces, a condition that often needs surgical decompression to restore normal CSF circulation. Abru...2014-01-01
462 Simpson, Jamesina J.Introducing a new method for FDTD modeling of electromagnetic wave propagation in magnetized plasmaComputational investigations of electromagnetic wave propagation in the upper atmosphere are important for studying space weather hazards, such as geomagnetically induced currents (GICs). GICs are currents generated in gas/oil pipelines, railroads, and electric power networks due to solar storms and...2014-01-01
463 Golden, Kenneth M.The lsing model and critical behavior of transport in binary composite mediaWe present a general theory for critical behavior of transport in binary composite media. The theory holds for lattice and continuum percolation models in both the static case with real parameters and the quasi-static case (frequency dependent) with complex parameters. Through a direct, analytic cor...2012-01-01
464 Balasubramonian, RajeevLOT-ECC: LOcalized and tiered reliability mechanisms for commodity memory systemsMemory system reliability is a serious and growing concern in modern servers. Existing chipkill-level mem- ory protection mechanisms suffer from several draw- backs. They activate a large number of chips on ev- ery memory access - this increases energy consump- tion, and reduces performance due to t...2012-01-01
465 Couldwell, William T.Management of meningiomas involving the transverse or sigmoid sinusMeningiomas that invade the transverse or sigmoid sinuses are uncommon tumors that are challenging to treat surgically. Although the risk of recurrence is associated with the extent of resection, complete removal of meningiomas in these locations must be balanced with avoidance of venous outflow obs...2013-01-01
466 Tiwari, AshutoshManifestation of two-channel nonlocal spin transport in the shapes of Hanle curvesThe dynamics of charge-density fluctuations in a system of two tunnel-coupled wires contains two diffusion modes with dispersion iω = Dq2 and iω = Dq2 + 2τt, where D is the diffusion coefficient and τt is the tunneling time between the wires. The dispersion of corresponding spin-density modes de...2014-01-01
467 Gerig, GuidoLongitudinal growth modeling of discrete-time functions with application to DTI tract evolution in early neurodevelopmentWe present a new framework for spatiotemporal analysis of parameterized functions attributed by properties of 4D longitudinal image data.

468 Khan, Faisal HabibMagnetic stimulation of mammalian peripheral nerves in vivo: An alternative to functional electrical stimulationFunctional electrical stimulation is the current gold standard for stimulating neuronal interfaces for functional neuromuscular and cortical applications, but it is not without its drawbacks. One such fault is the need to have direct electrical contact with the nerve tissue, and any side effect...2014-01-01
469 Rogachev, AndreyMagnetic-field dependent differential capacitance of polymer diodesUsing admittance spectroscopy, we found that bipolar organic diodes based on pi-conjugated polymer, 2-methoxy-5-(20-ethylhexyloxy), MEH-PPV, have strong divergent contribution to the device differential capacitance.

470 Gopalakrishnan, GaneshMAPPED: Predictive dynamic analysis tool for MPI applicationsAbstract-Formal dynamic analysis of MPI programs is critically important since conventional testing tools for message passing programs do not cover the space of possible non-deterministic communication matches, thus may miss bugs in the unexamined execution scenarios. While modern dynamic verificati...2012-01-01
471 Furse, Cynthia M.Manufacturing considerations for implantable antennasDesign of implantable antennas poses a unique set of challenges since antennas need to be small, biocompatible, and operate in the highly lossy environment of the human body. A recent review identified miniaturization challenges and how they have been managed in a variety of designs. [1] It also not...2013-01-01
472 Gondolo, PaoloThe effect of quark interactions on dark matter kinetic decoupling and the mass of the smallest dark halosThe kinetic decoupling of dark matter (DM) from the primordial plasma sets the size of the first and smallest DM halos. Studies of the DM kinetic decoupling have hitherto mostly neglected interactions between the DM and the quarks in the plasma. Here we illustrate their importance using two framewor...2012-01-01
473 Gerton, JordanEffect of magnetic Gd impurities on the superconducting state of amorphous Mo-Ge thin films with different thickness and morphologyWe studied the effect of magnetic doping with Gd atoms on the superconducting properties of amorphous Mo70Ge30 films.
