Almost all previous dynamic-sized lock-free data structures are either unable to free memory to the memory allocator when it is no longer required, or require special system or hardware support. In the only exception we are aware of, a single thread failure can prevent further memory reclamation (see full paper for reference). We recently posed a problem — the Repeat Offenders Problem (ROP) — a...

Capital Market Pressures and Earnings Management: Evidence from U.S. Dual-Class Firms Feng Chen In a dual-class share structure, one class of common stock typically has more votes per share than the other, but both classes have equal or similar cash flow rights per share. While this dual-class structure is likely to entrench management, it potentially reduces capital market pressures on manager...

OBJECTIVES Evaluate the academic experience and satisfaction of students enrolled in the dual PharmD/MBA degree program between the South Carolina College of Pharmacy and The Citadel's School of Business Administration. Compare grade point averages of students enrolled in the dual degree program with those of traditional student colleagues. METHODS A standardized satisfaction survey instrumen...

Introduction: Estimates of myocardial blood flow (MBF) from first-pass contrast-enhanced cardiac magnetic resonance (CMR) imaging require accurate measurement of the arterial input function (AIF) from the left-ventricular (LV) blood pool. Both dual-bolus [1] and dual-sequence [2,3] CMR methods have been proposed to maintain the linearity of the LV signal during the contrast passage. Several stu...

We propose two new Lagrangian dual problems for chance-con-strained stochastic programs based on relaxing nonanticipativity constraints. We compare the strength of the proposed dual bounds and demonstrate that they are superior to the bound obtained from the continuous relaxation of a standard mixed-integer programming (MIP) formulation. For a given dual solution, the associated Lagrangian rela...

The aim of this study was to compare the microtensile bond strength of two heat-pressed ceramics (leucite-based--IPS Empress Esthetic/Ivoclar Vivadent, and lithium disilicate-based --IPS e.max Press/Ivoclar Vivadent) to dentin with the use of conventional and self-adhesive resin cements. The occlusal surface of 60 intact human molars was removed and the dentin was exposed. Ceramic blocks were c...

A Heyting algebra is a distributive lattice with implication and a dual $BCK$-algebra is an algebraic system having as models logical systems equipped with implication. The aim of this paper is to investigate the relation of Heyting algebras between dual $BCK$-algebras. We define notions of $i$-invariant and $m$-invariant on dual $BCK$-semilattices and prove that a Heyting semilattice is equiva...

Background: The Singh index is an inexpensive simple method to evaluate bone density, commonly used to assess osteoporosis is based on the radiological appearance of the trabecular bone structure of the proximal femur on a plain antero-posterior (AP) radiograph. The purpose of this study was to compare between Singh index and bone mineral density measurement using dual energy X-ray abs...
