General two-party Secure Function Evaluation (SFE) allows mutually distrusting parties to (jointly) correctly compute any function on their private input data, without revealing the inputs. SFE, properly designed, guarantees to satisfy the most stringent security requirements, even for interactive computation. Two-party SFE can benefit almost any client-server interaction where privacy is requi...

We consider general secure function evaluation (SFE) of private functions (PF-SFE). Recall, privacy of functions is often most efficiently achieved by general SFE [17,18,9] of a Universal Circuit (UC). Our main contribution is a new simple and efficient UC construction. Our circuit UCk, universal for circuits of k gates, has size ∼ 1.5k log k and depth ∼ k log k. It is up to 50% smaller than th...

We present unified combinatorial characterizations of completeness for 2-party secure function evaluation (SFE) against passive and active corruptions in the information-theoretic setting, so that all known characterizations appear as special cases. In doing so we develop new technical concepts. We define several notions of isomorphism of SFE functionalities and define the “kernel” of an SFE fu...

The total oil content of soyflakes, canola seed and wetmilled corn germ were determined by analytical supercritical fluid extraction (SFE) with carbon dioxide as the extraction solvent. Results obtained by SFE were in excellent agreement with those obtained by a conventional Soxhlet technique with organic solvents. The analyticalscale SFE technique yielded average means within one standard devi...

Supercritical fluid extraction (SFE) of the volatile oil from Thymus vulgaris L. aerial flowering parts was performed under different conditions of pressure, temperature, mean particle size and CO(2) flow rate and the correspondent yield and composition were compared with those of the essential oil isolated by hydrodistillation (HD). Both the oils were analyzed by GC and GC-MS and 52 components...

Surface free energy (SFE) plays an important role in microfluidic device operation. Photosensitive glasses such as APEX offer numerous advantages over traditional glasses for microfluidics, yet the SFE for APEX has not been previously reported. We calculate SFE with the Owens/Wendt geometric method by using contact angles measured with the Sessile drop technique. While the total SFE for APEX is...

Due to increasingly stringent environmental regulations, supercritical fluid extraction (SFE) has gained wide acceptance in recent years as an alternative to conventional solvent extraction for separation of organic compounds in many analytical and industrial processes. In the past decade, SFE has been applied successfully to the extraction of a variety of organic compounds from herbs and other...

Pär Holmberg January 28, 2006 Abstract This paper derives a Supply Function Equilibrium (SFE) of a pay-as-bid auction (discriminatory auction), such as the balancing market for electric power in Britain. It is shown that a SFE always exists if the hazard rate of the perfectly inelastic demand is monotonically decreasing and marginal costs are non-decreasing. With demand following a Pareto distr...
