We consider the (3+1)-dimensional Maxwell theory in the situation where going around nontrivial paths in the spacetime involves the action of the duality transformation exchanging the electric field and the magnetic field, as well as its SL(2,Z) generalizations. We find that the anomaly of this system in a particular formulation is 56 times that of a Weyl fermion. This result is derived in two independent ways: one is by using the bulk symmetry protected topological phase in (4+1) dimensions characterizing the anomaly, and the other is by considering the properties of a (5+1)-dimensional superconformal field theory known as the E-string theory. This anomaly of the Maxwell theory plays an important role in the consistency of string theory.

In this work we introduce a system pipeline for the analysis of earth's electromagnetic field that is used to analyse precursors to earthquakes. Data gathered by the Swarm satellites are used to prese...
In this paper we explore the role of duality principles within the problem of rotation averaging, a fundamental task in a wide range of applications. In its conventional form, rotation averaging is st...
We show that supersymmetry is anomalous in N=1 superconformal quantum field theories (SCFTs) with an anomalous R symmetry. This anomaly was originally found in holographic SCFTs at strong coupling. He...
Exposure to electromagnetic field in long-term use of cell phones has increased concerns about serious health problems. Our aim was to survey the possible effects of electromagnetic field radiation (6...
Ebstein's anomaly of the tricuspid valve is a rare and heterogeneous form of congenital heart defect. The purpose of this study was to review the surgical experience with Ebstein's anomaly at a single...
The study is designed to evaluate the use of electromagnetic tracking in femoral derotation osteotomies. The goal is to raise the precision of the surgical procedure in order to improve th...
This research is being done to better understand the pulmonary consequences of completing an ultra marathon at altitude and a sea level city.
In vitro studies suggest that low levels of amplitude-modulated electromagnetic fields may modify cell growth. We have identified specific frequencies that may block cancer cell growth. We...

Medical know-how concerning uterus transplantation will be transferred to new site by structured process involving theory, animal workshops and a clinical feasibility study on human subjec...
An interdisciplinary study dealing with the transmission of messages or signals, or the communication of information. Information theory does not directly deal with meaning or content, but with physical representations that have meaning or content. It overlaps considerably with communication theory and CYBERNETICS.
A psychological theory based on dimensions or categories used by a given person in describing or explaining the personality and behavior of others or of himself. The basic idea is that different people will use consistently different categories. The theory was formulated in the fifties by George Kelly. Two tests devised by him are the role construct repertory test and the repertory grid test. (From Stuart Sutherland, The International Dictionary of Psychology, 1989)
The theory that the radiation and absorption of energy take place in definite quantities called quanta (E) which vary in size and are defined by the equation E=hv in which h is Planck's constant and v is the frequency of the radiation.
The theory that infectious agents, symbiotic microorganisms, and parasites are normal stimulants for the maturation of the immune system toward a balanced immune response. The theory predicts that lack of such stimulation leads to allergies and AUTOIMMUNE DISEASES.
The ability to attribute mental states (e.g., beliefs, desires, feelings, intentions, thoughts, etc.) to self and to others, allowing an individual to understand and infer behavior on the basis of the mental states. Difference or deficit in theory of mind is associated with ASPERGER SYNDROME; AUTISTIC DISORDER; and SCHIZOPHRENIA, etc.
