We consider some questions of naturalness which arise when one considers conventional field theories in the presence of gravitation: the problem of global symmetries, the strong CP problem, and the cosmological constant problem. Using string theory as a model, we argue that it is reasonable to postulate weakly broken global discrete symmetries. We review the arguments that gravity is likely to ...

Abstract = findings" Key Phrase "Key Phrase = group" Age Group "Age Group = Adulthood" Population "Population = Human" Population Location "Population Location = US" Publication Type "Publication Type = Empirical-Study" mean performance of both models averaged over the datasets. For example, once a user has read the first 60% of the prioritised articles using the one reason model, they have see...

We have recovered terminal chromosome deletions of the X chromosome of Drosophila [Df(1)RT; RT = receding tips] that break in various positions of the yellow gene (y) region and delete all distal DNA sequences. Terminal DNA fragments are heterogeneous in length. Molecular cloning and sequencing of the terminal DNA fragments revealed that the broken ends of the deleted chromosomes do not carry a...

Edges produced by existing edge detection algorithms often contain discontinuities. Edge linking as a post-processing step is an important step for computer vision and pattern recognition. We present a real-time algorithm and its VLSI implementation for linking broken edges. First, all broken edge points inside a 12 12 moving window are identiied. The 12 12 window scans the input gray level edg...

A binary CSP instance satisfying the broken-triangle property (BTP) can be solved in polynomial time. Unfortunately, in practice, few instances satisfy the BTP. We show that a local version of the BTP allows the merging of domain values in arbitrary instances of binary CSP, thus providing a novel polynomial-time reduction operation. Extensive experimental trials on benchmark instances demonstra...

Introduction A significant portion of patients treated in emergency departments have nasal fracture. It is important that the otolaryngologist know how to treat such damage. Objectives To evaluate the effectiveness of nasal fracture reduction under local anesthesia and tolerance to the procedure. Methods Twenty-four patients treated in the emergency department with closed reduction under local ...

We consider contributions of R-parity conserving softly broken supersymmetry (SUSY) to neutrinoless double beta (0νββ) decay via the (B-L)-violating sneutrino mass term. The latter is a generic ingredient of any weak-scale SUSY model with a Majorana neutrino mass. The new R-parity conserving SUSY contributions to 0νββ are realized at the level of box diagrams. We derive the effective Lagrangian...

According to amoebic self theory, the boundary defining the self encompasses 3 levels of self-representation--bodily, social, and spatial-symbolic. Study 1 related a newly developed measure of individual differences in sensitivity to boundary threat across these 3 domains to values and disgust sensitivity. Four subsequent studies focused on spatial-symbolic threat sensitivity and related it to ...

In November 2003, after receiving a discrimination complaint from a county employee, the Los Angeles County Office of Affirmative Action Compliance sent a memo to all its equipment vendors asking that they stop using the words “master” and “slave” in reference to computer hardware and other equipment.{1} The memo read in part: “Based on the cultural diversity and sensitivity of Los Angeles Coun...
