The enhancon mechanism in string theory [PDF]
, 2002 The enhancon mechanism is a specific phenomenon in string theory which resolves a certain naked spacetime singularity arising in the supergravity description related to N = 2 supersymmetric pure gauge theory.

Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND Arabinoxylans (AX), abundant in wheat bran, represent a valuable yet underutilized fraction of cereal milling by‐products. In this study, an AX‐enriched fraction obtained from durum wheat meal (DWM), produced from defatted durum wheat germ and debranning fractions, was incorporated at increasing levels (0–25%) into pea starch ...

Superconducting p-branes and extremal black holes [PDF]
, 1998 In Einstein-Maxwell theory, magnetic flux lines are "expelled" from a black hole as extremality is approached, in the sense that the component of the field strength normal to the horizon goes to zero.

Land Degradation &Development, EarlyView.ABSTRACT Straw return (SR) and controlled‐release nitrogen fertilizers application can improve soil structure, enhance soil water retention, and promote crop growth. However, the mechanisms through which SR and controlled‐release nitrogen fertilizers application jointly modulate soil physical and chemical properties remain unclear.

Entanglement entropy for open bosonic strings on Dp-branes
Physics Letters B, 2018 We study the entanglement entropy for open bosonic strings on multiple Dp-branes by using the covariant open string field theory. Choosing one of the spatial coordinates which are tangential to the hyperplane on which Dp-branes are located, we divide the

Non-static brane probes, topological charges and calibrations [PDF]
, 2004 In this thesis we consider probe branes in 10- and 11-dimensional supergravity backgrounds. Firstly, we consider probing a class of 11-dimensional backgrounds with giant gravitons. These backgrounds arise from lifting solutions of 4-dimensional U(1)(^4)

Public Administration and Development, EarlyView.ABSTRACT The lack of a common variable for comparison has been a major obstacle to the development of Comparative Public Administration (CPA). State autonomy enables an integrative contextualization approach, allowing both the analysis of contextual individual country experiences and the generation of generalized comparable knowledge.

Black p-branes in heterotic string theory
Journal of High Energy PhysicsHeterotic string theory has nonsupersymmetric branes whose existence is suggested by the cobordism conjecture. We numerically construct static, spherically symmetric, and asymptotically flat black brane solutions in ten-dimensional heterotic superstring ...

Gravity in spacetimes with cosmological constants [PDF]
, 2009 This thesis is composed of two parts: gravity in the spacetime with a negative/positive cosmological constant. The first part, which is the negative case, devotes to constructing the IIB supergravity dual solution in AdS/CFT correspondence for N = (1, 0)

Polymer Engineering &Science, EarlyView.Preparation of sustainable PEG‐based ssPCMs using a PC‐based low‐cos filler and G as a thermal enhancer. PEG 6000 is incorporated into the PC/G matrix through mixing to obtain the shape‐stabilized PCM for thermal energy storage applications. ABSTRACT This study investigates the development of a novel shape‐stabilized phase change material (ssPCM ...
