In this paper‎, ‎first‎, ‎a numerical method is presented for solving a class of linear Fredholm integro-differential equation‎. ‎The operational matrix of derivative is obtained by introducing hybrid third kind Chebyshev polynomials and Block-pulse functions‎. ‎The application of the proposed operational matrix with tau method is then utilized to transform the integro-differential equations to...

The tau protein is a neuronal microtubule-associated protein. Apart of its physiological function-the binding to and stabilization of microtubules-tau is found in Alzheimer's disease brain as insoluble fibers, the so-called "paired helical filaments" (PHFs). Investigating the fundamentals of tau polymerization is indispensable for identifying inhibitory conditions or compounds preventing PHF fo...

We outline Tau, a practical and extensible hybrid theorem prover for first-order predicate calculus with identity. Tau is flexible and user-configurable, accepts the KIF Language, is implemented in Java, and has multiple user interfaces. Tau combines rule-based problem rewriting with Model Elimination, uses Brand’s Modification Method to implement identity, and accepts user-configurable heurist...

UNLABELLED Abstract Objective: This study investigated the effects of standard eye movement desensitization and reprocessing (EMDR) protocol in chronically dependent patients. We propose that reprocessing traumatic memories with EMDR would lead to measurable changes of addiction symptoms. METHOD Twelve patients with alcohol and/or drug dependency were randomly assigned to one of two treatment...

OBJECTIVE Amyloid 1-42 (Aβ42) and tau in cerebrospinal fluid are currently used as markers for diagnosis of Alzheimer's disease. Conflicting reports exist regarding their plasma levels in Alzheimer's disease patients. A meta-analysis was performed to statistically validate the use of plasma Aβ42 and tau as biomarkers for Alzheimer's disease. METHODS Different databases were searched using the...

He, Ying Ph.D., Purdue University, December 2013. Efficient Spectral-Element Methods for Acoustic Scattering and Related Problems. Major Professor: Jie Shen . This dissertation focuses on the development of high-order numerical methods for acoustic and electromagnetic scattering problems, and nonlinear fluid-structure interaction problems. For the scattering problems, two cases are considered: ...

It is highly nontrivial to what extent we can deduce the relaxation behavior of a quantum dissipative system from spectral gap Liouvillian that governs time evolution density matrix. We investigate processes exhibits skin effect, which means eigenmodes are localized exponentially close boundary system, and find timescale for reach steady state depends not only on $\Delta$ but also localization ...

The total gas mass of a protoplanetary disk is a fundamental, but poorly determined, quantity. A new technique has been demonstrated to assess directly the bulk molecular gas reservoir of molecular hydrogen using the HD J=1–0 line at 112 μm. In this work we present a Herschel Space Observatory survey of six additional T Tauri disks in the HD line. Line emission is detected at >3σ significance...

He i l10830 profiles acquired with Keck’s NIRSPEC for six young low-mass stars with high disk accretion rates (AS 353A, DG Tau, DL Tau, DR Tau, HL Tau, and SVS 13) provide new insight into accretion-driven winds. In four of the stars, the profiles have the signature of resonance scattering, and they possess a deep and broad blueshifted absorption that penetrates more than 50% into the 1 mm cont...
