The Cambrian fossil Amiskwia sagittiformis has puzzled palaeontologists for more than a century, but recent re-investigation of its morphology suggested close relationship with the bilaterian clade Gnathifera, comprising Rotifera, Gnathostomulida and Micrognathozoa. Since already been considered closely related to Chaetognatha, this new interpretation supports molecular developmental studies fi...

INTRODUCTION Cognitive-behavioural therapy for insomnia (CBT-I) leads to insomnia symptom improvements in a substantial proportion of patients. However, not everyone responds well to this treatment, and it is unclear what determines individual differences in response. The broader aim of this work is to examine to what extent response to CBT-I is due to genetic and environmental factors. The pur...

We develop a methodology for extracting small investor sentiment from stock message boards. Five distinct classifier algorithms coupled by a voting scheme are found to perform well against human and statistical benchmarks. Time series and cross-sectional aggregation of message information improves the quality of the resultant sentiment index. Empirical applications evidence a relationship with ...

The production of a motion picture is an expensive, risky endeavor. During the five-year period from 2008 through 2012, approximately 90 films were released in the United States with production budgets in excess of $100 million. The majority of these films failed to recoup their production costs via gross domestic box office revenues. Existing decision support systems for pre-production analysi...

Chomsky [Chomsky, N., 1965. Aspects of The Theory of Syntax. MIT Press, Cambridge, Mass; Chomsky, N., 1986. Knowledge of Language: its Nature, Origin, and Use. Praeger, New York] presents a series of arguments for an innate syntactic component of the language faculty. Do the arguments proposed at that time still stand, or have they been overridden by newer proposals? The current paper emphasize...

Abstract Study question Are there differences in the ongoing pregnancy rate (OPR) using Cyclogest® versus Progeffik® at a dose of 800 mg daily as luteal phase support? Summary answer The administration support shows higher rates cycle hormone replacement therapy (HRT) with own oocytes What is known already importance serum progesterone levels around time embryo transfer patients undergoing FET ...

In the process of drying, a sessile drop containing nonvolatile solutes such as polymers, nanocrystals, and carbon nanotubes readily self-assembles into a number of concentric “coffee rings” through the repetitive “stick–slip” motion of a threephase contact line. However, owing possibly to convection and a lack of control over the evaporation process of the drop, the rings are often irregular a...

Transgenic seeds in both India (Bt cotton) and Brazil (glyphosate-resistant soybeans) spread widely and rapidly through farming communities outside the reach of biosafety or bioproperty institutions. Stealth transgenics are saved, cross-bred, repackaged, sold, exchanged and planted in an anarchic agrarian capitalism that defies surveillance and control of firms and states. The outcome is more p...

We have studied the binding of actin to the erythrocyte membrane by a novel application of falling ball viscometry . Our approach is based on the notion that if membranes have multiple binding sites for F-actin they will be able to cross-link and increase the viscosity of actin . Spectrinand actin-depleted inside-out vesicles reconstituted with purified Spectrin dimer or tetramer induce large i...

The genomics revolution in biology has enabled technologies with unprecedented potential; genetic engineering is changing the terrain of development studies. Societies have reacted with indifference or appreciation to genetically engineered pharmaceuticals, beginning with insulin; yet for food and agriculture, a globally contentious politics and unprecedented policy dilemmas have arisen. Transg...
