IEEE Photonics Journal, 2012 We demonstrate a novel technique for photonic generation of few-cycle millimeter-wave (MMW) pulse using a WR-10 waveguide and near-ballistic unitraveling carrier photodiode (NBUTC-PD)-based photonic-transmitter-mixer (PTM).

A Slot-Based Surface Plasmon-Polariton Waveguide With Long-Range Propagation and Superconfinement
IEEE Photonics Journal, 2012 A full-vector spectral element method (SEM) is applied to model and simulate surface plasmon-polariton (SPP) waveguides. Gauss-Lobatto-Legendre (GLL) polynomials are used to construct higher-order basis functions to achieve spectral accuracy.

, 2012 Koplienko gave a trace formula for perturbations of self-adjoint operators by operators of Hilbert-Schmidt class $\mathcal{B}_2(\mathcal{H})$. Recently Gesztesy, Pushnitski and Simon gave an alternative proof of the trace formula when the operators ...

Multiple commutator formulas [PDF]
Israel Journal of Mathematics, 2012 Let A be a quasi-finite R-algebra (i.e., a direct limit of module finite algebras) with identity. Let I_i, i=0,...,m, be two-sided ideals of A, \GL_n(A,I_i) the principal congruence subgroup of level I_i in GL_n(A) and E_n(A,I_i) be the relative elementary subgroup of level I_i.

Algebraic Yuzvinski Formula [PDF]
, 2013 In 1965 Adler, Konheim and McAndrew defined the topological entropy for continuous self-maps of compact spaces. Topological entropy is very well-understood for endomorphisms of compact Abelian groups. A fundamental result in this context is the so-called

Microscopic mass formulas [PDF]
Physical Review C, 1995 By assuming the existence of a pseudopotential smooth enough to do Hartree-Fock variations and good enough to describe nuclear structure, we construct mass formulae that rely on general scaling arguments and on a schematic reading of shell model calculations.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Families of children with cancer experience significant financial strain, even with universal healthcare. Indirect costs, such as productivity losses and non‐medical expenses, are rarely included in economic evaluations, and little is known about how effectively financial aid programmes alleviate this burden. Childhood brain tumours

Volumetric Method of Moments and Conceptual Multilevel Building Blocks for Nanotopologies
IEEE Photonics Journal, 2012 On the basis of the relationship between charge dimensionality and singular field behavior, it is proven that in a volumetric description of a volume current carrying topology, half rooftops of different binary hierarchical level are allowed without ...

Comparison of the Kane formula with existing formulas for intraocular lens power selection
BMJ Open Ophthalmology, 2019 Objective To compare the accuracy of a new intraocular lens (IOL) power formula (Kane formula) with existing formulas using IOLMaster, predominantly model 3, biometry (measures variables axial length, keratometry and anterior chamber depth) and optimised
