We describe an algorithm capable of extracting the unloaded quality factor and resonant frequency microwave resonators from vector S-parameters. Both symmetrical (Lorentzian) asymmetrical (Fano) transmission responses are supported. The performs adaptive outlier removal to discard measurement points affected by noise or distortion. It removes effects caused imperfections in device (such as mode...

It is important to obtain structure-activity relationship (SAR) data across cationic lipids for the self-assembly and non-viral intracellular delivery of siRNA. The aims of this work are to carry out a SAR study on the efficiency of asymmetrical N,N-diacyl spermines in siRNA delivery and EGFP reporter gene silencing, with comparisons to selected mixtures composed of symmetrical N,N-diacyl sperm...

Regional differentiation based on size, form, and orientation angle of the soma of individual neurons in human post-mortem hippocampus was determined through correlations between pairs of hippocampal subfields in each side separately. The neurons were previously measured on a computer. In the normal cases, a left-right asymmetrical pattern of regional differentiation based on soma size emerged,...

In this work, the dynamics of bioconvection process gravitactic microorganisms enclosed in a rectangular cavity, is analyzed. The dimensionless cell and energy conservation equations are coupled with vorticity-stream function formulation. Then, effects Rayleigh number heating source on discussed. results based streamlines, concentration temperature contours obtained through numerical simulation...

This study is an attempt to determine how much individuals should invest in social communication, depending on the type of relationships they may form. Two simple models of social relationships are considered. In both models, individuals emit costly signals to advertise their "quality" as potential friends. Relationships are asymmetrical or symmetrical. In the asymmetrical condition (first mode...

It is important to obtain structure-activity relationship (SAR) data across cationic lipids for the self-assembly and nonviral intracellular delivery of siRNA. The aims of this work are to carry out a SAR study on the efficiency of asymmetrical N(4),N(9)-diacyl spermines in siRNA delivery and EGFP reporter gene silencing, with comparisons to selected mixtures composed of symmetrical N(4),N(9)-d...

OBJECTIVES To determine patterns on pain diagrams and corresponding diagnoses in patients referred to a rheumatology clinic and their sensitivity, specificity, and positive and negative predictive values (PPV and NPV, respectively). METHODS All new adult patient referrals from two rheumatologists over 6 years were reviewed and eligible if a pain diagram had been completed and they were not pr...
