An Assessment of Discursive Changes in Islamic Metaphysics –Thubūt as an Interpretation of the Concept of Possibility or Nonexistence and the Nonexistence of Nonexistence

open access: yesIlahiyat Studies, 2010
In its beginnings, Sufism was a moral movement concerned with asceticism (zuhd) and poverty (faqr). Later, Sufism's second period, which was called "Sunnī Sufism" with problems arising from a spiritual life of which the theoretical basis is unknown, was again within the limits of a moral content.

What to Make and How to Make It: Combining Machine Learning and Statistical Learning to Design New Materials

open access: yesAdvanced Intelligent Discovery, EarlyView.
Combining machine learning and probabilistic statistical learning is a powerful way to discover and design new materials. A variety of machine learning approaches can be used to identify promising candidates for target applications, and causal inference can help identify potential ways to make them a reality.

Nonexistence results of solutions for some fractional $p$-Laplacian equations in $\mathbb{R}^{N}$

open access: yesElectronic Journal of Qualitative Theory of Differential Equations
In the present paper, we study the nonexistence of nontrivial weak solutions to a class of fractional $p$-Laplacian equation in two cases which are $sp > N$ and $sp < N$.

Nonexistence theorems for traversable wormholes

open access: yes, 1999
Gauss-Bonnet formula is used to derive a new and simple theorem of nonexistence of vacuum static nonsingular lorentzian wormholes. We also derive simple proofs for the nonexistence of lorentzian wormhole solutions for some classes of static matter such ...

Elastic Fast Marching Learning from Demonstration

open access: yesAdvanced Intelligent Systems, EarlyView.
This article presents Elastic Fast Marching Learning (EFML), a novel approach for learning from demonstration that combines velocity‐based planning with elastic optimization. EFML enables smooth, precise, and adaptable robot trajectories in both position and orientation spaces.

Nonexistence of positive solutions for a nonpositone system in a ball

open access: yesElectronic Journal of Differential Equations, 2015
In this article, we prove the nonexistence of positive solutions for a nonpositone system in a ball when the nonlinearities may have more than one zero.

"Boundary blowup" type sub-solutions to semilinear elliptic equations with Hardy potential

open access: yes, 2007
Semilinear elliptic equations which give rise to solutions blowing up at the boundary are perturbed by a Hardy potential. The size of this potential effects the existence of a certain type of solutions (large solutions): if the potential is too small ...

The nonexistence of regularization operators

open access: yesJournal of Mathematical Analysis and Applications, 2003
With references to applications in physics the author discusses the well known problem of regularization of generalized functions. As is known, there exist various procedures to regularize some concrete classes of generalized functions. For generalized functions on the real line the author shows that there cannot exist a unique procedure which provides

A Soft Wearable Robot for Vertical Jump Enhancement via a Pneumatic Energy‐Storing Propulsion Actuator and Triarticular Kinetic‐Chained Structure

open access: yesAdvanced Intelligent Systems, EarlyView.
The Jump‐Enhancing Textile Suit integrates the Pneumatic Energy‐Storing Propulsion Actuator (PESPA) and the Triarticular Kinetic‐Chained Structure (TKiCS). PESPA stores elastic energy under pneumatic pressure and releases it during the propulsive phase to augment movement.

On the critical behavior for a Sobolev-type inequality with Hardy potential

open access: yesComptes Rendus. Mathématique
We investigate the existence and nonexistence of weak solutions to the Sobolev-type inequality $ -\partial _t(\Delta u)-\Delta u+ \frac{\sigma }{|x|^2}u \ge |x|^{\mu }|u|^p$ in $(0,\infty )\times B$, under the inhomogeneous Dirichlet-type boundary ...
