Testing Halfspaces
Published 2012“…This paper addresses the problem of testing whether a Boolean-valued function f is a halfspace, i.e., a function of the form f(x)=sgn(w [dot] x-theta). We consider halfspaces over the continuous domain R[superscript n] (endowed with the standard multivariate Gaussian distribution) as well as halfspaces over the Boolean cube {-1,1}[superscript n] (endowed with the uniform distribution). …”

Functional Signatures and Pseudorandom Functions
Published 2014“…In a functional pseudorandom function, in addition to a master secret key that can be used to evaluate the pseudorandom function F on any point in the domain, there are additional secret keys for a function f, which allow one to evaluate F on any y for which there exists an x such that f(x) = y. As a special case, this implies pseudorandom functions with selective access, where one can delegate the ability to evaluate the pseudorandom function on inputs y for which a predicate P(y) = 1 holds. …”

SYNTHESIS AND SUPERCONDUCTING PROPERTIES OF THE STRONTIUM COPPER OXY-FLUORIDE SR2CUO2F2+DELTA
Published 1994“…The result is a superconducting oxy-fluoride in which fluorine plays a dominant structural role, rather than merely being an electronic dopant as in La2CuO4F(x) (ref. 2) and Nd2CuO(4- x)F(y) (ref. 3). | High-pressure synthesis has proved a useful technique for obtaining new, metastable copper oxide superconductors; for example, oxygen insertion into Sr2CuO3 at 6 GPa (ref. 1) yields superconducting Sr2CuO3.1, with transition temperature Tc = 70 K, in which the superconducting CuO2 layers are generated by pressure-induced oxygen migration from apical to equatorial sites. …”

Problems of stability and well-posedness in the calculus of variations and related PDEs
Published 2022“…Regarding the first topic on generic Tykhonov well-posedness, we prove that by introducing a linear perturbation term $\xi$ to a variational integral of the form $J(u) = \int_{\Omega} F(x, u, \nabla u) \,dx$ satisfying a mild growth condition on the negative part of the integrand $F$, and a coercivity condition for $J$, the perturbed functional $J - \xi$ admits a unique strong minimizer in the Dirichlet class $W^{1,p}_{g}(\Omega ; \mathbb{R}^N)$ for all $\xi$ in a dense $G_\delta$-subset of $W^{1,p}_{0}(\Omega ; \mathbb{R}^N)^*$ for any $p \ge 1$. …”

Limits on Leptonic TeV Emission from the Cygnus Cocoon with Swift-XRT
Published 2023-01-01“…By assuming that the X-ray intensity traces the TeV intensity and follows a ${dN}/{dE}\propto {E}^{-2.5}$ spectrum, we obtained a 90% upper limit of F _X < 8.7 × 10 ^−11 erg cm ^−2 s ^−1 or <5.2 × 10 ^−11 erg cm ^−2 s ^−1 on the X-ray flux of the entire Cygnus Cocoon between 2 and 10 keV depending on the choice of hydrogen column density model for the absorption. …”

Observations of Aharonov-Bohm Conductance Oscillations in CVD-Grown Graphene Rings at 4K
Published 2023-01-01“…We present the observations of Aharonov-Bohm (AB) oscillations in chemical vapor deposition (CVD)-grown graphene rings via magnetotransport measurements at 4K under out-of-plane external magnetic fields up to +/−2.1 T. Incorporating a baseline subtraction of the original conductance data allowed us to observe two-terminal conductance oscillations with a spacing of ΔB<sub>AB</sub> of 3.66 to 32.9 mT from the ring with an inner radius of 200 nm and arm-width of 400 nm, and spacing of ΔB<sub>AB</sub> from 2.1 mT to 8.2 mT from the ring with an inner radius of 400 nm and an arm-width of 400 nm. …”
