Finiteness of multi-loop superstring amplitudes [PDF]
arXiv, 1998 Superstring amplitudes of an arbitrary genus are calculated through super-Schottky parameters by a summation over the fermion strings. For a calculation of divergent multi-loop fermion string amplitudes a supermodular invariant regularization procedure is used. A cancellation of divergences in the superstring amplitudes is established.

Subthalamic Nucleus Oscillatory Characteristics in Meige, Cervical Dystonia and Generalized Dystonia
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Deep brain stimulation offers a unique opportunity to record neural activity of the basal ganglia. While much work in dystonia has focused on the globus pallidus internus, expanding research to investigate subthalamic nucleus (STN) activity in various dystonia types is critical to provide a comprehensive understanding of dystonia ...

Sound Quality and Striking Position of a Conga Drum [PDF]
Journal of Science International School Bangkok, 2014 The relationship between the location at which a drum membrane was struck and the quality of sound produced was investigated by striking the drum at several distances between the center and the rim.

Concatenated Codes for Amplitude Damping
, 2016 We discuss a method to construct quantum codes correcting amplitude damping errors via code concatenation. The inner codes are chosen as asymmetric Calderbank-Shor-Steane (CSS) codes.

Quantum Extended Arithmetic Veneziano Amplitude [PDF]
arXiv, 2006 The Veneziano amplitude for the tree-level scattering of four tachyonic scalar of open string theory has an arithmetic analogue in terms of the p-adic gamma function. We propose a quantum extension of this amplitude using the q-extended p-adic gamma function given by Koblitz.

Fujita's Conjecture and Frobenius amplitude
, 2008 We prove a version of Fujita's Conjecture in arbitrary characteristic, generalizing results of K.E. Smith. Our methods use the Frobenius morphism, but avoid tight closure theory.

Tree Amplitudes in Gauge and Gravity Theories [PDF]
arXiv, 2005 Gauge theory amplitudes in a non-helicity format are generated at all $n$-point and at tree level. These amplitudes inherit structure from $\phi^3$ classical scattering, and the string inspired formalism is used to find the tensor algebra. All of the classical gravity amplitudes are also given.

Advanced Biology, EarlyView.In this article, the establishment and characterization of a self‐assembled 3D BBB spheroid model using human induced pluripotent stem cell (hiPSC)‐derived and primary cells is reported. Spheroids demonstrate in‐vivo like tight junction ultrastructure and, in comparison to 2D mono‐cultures, higher transcript expression of BBB specific genes.

Advanced Biology, EarlyView.The successful in situ polymerization of microtubules in giant polymer‐lipid hybrid vesicles is illustrated. The microtubules formed in the giant hybrid vesicles exhibit different morphologies including lumenal network formation and membrane association. Abstract Creating artificial cells with a dynamic cytoskeleton, akin to those in living cells, is a
