We prove that the validity of the recently proposed dressed, asymptotic Bethe ansatz for the planar AdS/CFT system is indeed limited at weak coupling by operator wrapping effects. This is done by comparing the Bethe ansatz predictions for the four-loop anomalous dimension of finite-spin twist-two operators to BFKL constraints from high-energy scattering amplitudes in N = 4 gauge theory. We find...

We examine the dynamics of extended branes, carrying lower dimensional brane charges, wrapping black holes and black hole microstates in M and Type II string theory. We show that they have a universal dispersion relation typical of threshold bound states with a total energy equal to the sum of the contributions from the charges. In near-horizon geometries of black holes, these are BPS states, a...

Enclosing a component within a software “wrapper” is a well-established way of adapting components for use in new environments. This paper presents an overview of an experimental evaluation of the use of a wrapper to protect against faults arising during the (simulated) operation of a practical and critical system; the specific context is a protective wrapper for an off-the-shelf software compo...

BACKGROUND Keeping abdominal surgery patients warm is common and warming methods are needed in power outages during natural disasters. We aimed to evaluate the efficacy of low-cost, low-power warming methods for maintaining normothermia in abdominal surgery patients. METHODS Patients (n = 160) scheduled for elective abdominal surgery were included in this prospective clinical study. Five warm...

Inside the QFT and TFT frame is developed a geometrical and topological model of one wrapping energy particle or “axion” to establish the diffeomorphic relation between space and time through of universal coverings. Then is established a scheme that relates both aspects, time and space through of the different objects that these include and their spectrum that is characterized by their wrapping...

“H istones and Chromatin”, a new review series in EMBO Reports and The EMBO Journal on histones, the chief protein components of chromatin, provides a state-of-the-art focus on molecular mechanistic understanding of the regulation of chromatin. The review series is centered on the histone code hypothesis, rather than the epigenetic code— i.e. excluding DNA modifications. Since the histone code ...

We explore the descriptive power, in terms of syntactic phenomena, of a formalism that extends TreeAdjoining Grammar (TAG) by adding a fourth level of hierarchical decomposition to the three levels TAG already employs. While extending the descriptive power minimally, the additional level of decomposition allows us to obtain a uniform account of a range of phenomena that has heretofore been diff...

Aortic aneurysm is a pathology that involves the enlargement of the aortic diameter and has risk factors including aortic dissection. Aneurysm wrapping and stent placement has been used in the treatment of aneurysms. This study aimed to investigate the biomechanical effects of wrapping and stenting on aneurysm. The three-layered aortic aneurysm were created and fluid structure interaction were ...

Wrapping external components by scripts can be a performance bottleneck if inter-language bridging is frequent. Piccola is a pure composition language that wraps components according to a specific composition style. This wrapping must be efficient, since even arithmetic operations are done by external components. In this paper, we present how to use partial evaluation to overcome much of the ov...

BACKGROUND External wrapping is a surgical method performed to prevent the dilatation of the aorta and to decrease the risk of its dissection and rupture. However, it is also believed to cause degeneration of the aortic wall. A biomechanical analysis was thus performed to assess the stress of the aortic wall subjected to external wrapping. METHODS A stress analysis using the finite elements m...
