Fine-tuning helper Ts
Lethal shock is subverted by crippling a family of G proteins in endothelial cells, according to Korhonen and colleagues on page 411. Bee stings or other allergens can cause anaphylactic shock in severely allergic individuals by triggering mast cell activation and the release of anaphylactic mediators like histamine and platelet activating factor (PAF). At high enough levels, these mediators ca...
متن کاملThe Fine-Tuning Argument
The Fine-Tuning Argument (FTA) is a variant of the Design Argument for the existence of God. In this paper the evidence of fine-tuning is explained and the Fine-Tuning Design Argument for God is presented. Then two objections are covered. The first objection is that fine-tuning can be explained in terms of the existence of multiple universes (the ‘multiverse’) plus the operation of the anthropi...
متن کاملFine Tuning Gene Regulation
in gene regulation. from many phyla is now making the use of alignments of hundreds or even thousands of genes a standard procedure. These studies have led to a widely accepted phylogeny of all animal phyla that has radically changed our views of animal evolution ( 3). Premolecular phylogenies generally envisaged a gradual increase in complexity from the earliest animals without a body cavity o...
متن کاملMeasures of Fine Tuning
Fine-tuning criteria are frequently used to place upper limits on the masses of superpartners in supersymmetric extensions of the standard model. However, commonly used prescriptions for quantifying naturalness have some important shortcomings. Motivated by this, we propose new criteria for quantifying fine tuning that can be used to place upper limits on superpartner masses with greater fideli...
متن کاملFine Tuning Algorithmic Skeletons
Algorithmic skeletons correspond to a high-level programming model that takes advantage of nestable programming patterns to hide the complexity of parallel/distributed applications. Programmers have to: define the nested skeleton structure, and provide the muscle (sequential) portions of code which are specific to a problem. An inadequate structure definition, or inefficient muscle code can lea...
