A causally connected superluminal Warp Drive spacetime [PDF]
arXiv, 2002 It will be shown that while horizons do not exist for warp drive spacetimes traveling at subluminal velocities horizons begin to develop when a warp drive spacetime reaches luminal velocities. However it will be shown that the control region of a warp drive ship lie within the portion of the warped region that is still causally connected to the ship ...

An Ultrathin and Lightweight Soft Inflatable Actuator for Natural Tactile Sensory Feedback
Advanced Intelligent Systems, EarlyView.A lightweight, ultrathin soft actuator mimics natural touch by delivering strong, multimodal haptic feedback through pressure and vibration. Tested on both able‐bodied individuals and amputees, it achieves high sensory precision in a compact form. Its simplicity, power, and adaptability hint at transformative applications in prosthetics, immersive ...

A Scalable Vector Graphics Warping System for Anthropomorphizing Game Characters
IEEE AccessHow can scalable vector graphics (SVG) data of human faces be transformed to resemble specific animal faces? Since the early $20^{th}$ century, multimedia featuring animals has garnered significant attention, particularly as interest in anthropomorphic

arXiv, 2011 In this paper we study the space of solutions to an overdetermined linear system involving the Hessian of functions. We show that if the solution space has dimension greater than one, then the underlying manifold has a very rigid warped product structure.

Synthesis of Benzodithieno[5.5.5.6]Fenestranes: Unexpected Epimerization and Regiochemical Outcomes
Asian Journal of Organic Chemistry, EarlyView.Isomeric [5.5.5.6]fenestranes annulated with one benzene and two thiophene rings are accessible via di‐2‐ and di‐3‐thienylspirane intermediates. The key double cyclization step involves surprising stereoselectivity and regioselectivity. In particular, cis‐di(2‐thienyl)spirane precursors lead to the all‐cis‐fenestrane skeleton by an unexpected acid ...

On Doubly Warped Product Finsler Manifolds [PDF]
arXiv, 2011 In this paper, we introduce horizontal and vertical warped product Finsler manifold. We prove that every C-reducible or proper Berwaldian doubly warped product Finsler manifold is Riemannian. Then, we find the relation between Riemmanian curvatures of doubly warped product Finsler manifold and its components, and consider the cases that this manifold ...

Thiophene Containing Polycyclic Aromatic Hydrocarbon Monkey Saddles
Asian Journal of Organic Chemistry, EarlyView.A series of thiophene containing polycyclic aromatic hydrocarbon monkey saddles is presented. The core structure was successfully functionalized to tune the optoelectronic properties and furthermore path the way to use these monkey saddles as building block, for example for oligomeric structures as well as organic cage compounds.

Animal Models and Experimental Medicine, EarlyView.Our study used behavioral tests, laser speckle flowmetry, long‐term potentiation, histochemical staining, molecular experiments, and voxel‐based morphometry to evaluate the hippocampal impairments. It demonstrates early functional and structural impairments in the hippocampus contributing to learning and memory deficits after 1 month of BCAS ...

Angewandte Chemie, EarlyView.Different regions of the electrode/electrolyte interface such as the interfacial layer and diffuse double layer are spectroscopically discerned by analyzing multidimensional time‐variance within a matrix of time‐resolved infrared spectra. In this way, discrete events relating to reorientation of water molecules in the double layer are elucidated ...
