Biotechnology and Bioengineering, EarlyView.ABSTRACT Generation of CAR‐T cell therapies relies predominantly on lentiviral vectors (LVs). As in vivo CAR‐T trials progress, demand for larger quantities of higher‐potency LV is expected. However, primary capture by anion‐exchange chromatography (AIEX) remains a major manufacturing bottleneck from use of adsorbents not tailored to LVs, leading to ...

An approximate solution of the Blasius problem using spectral method
Partial Differential Equations in Applied MathematicsThis paper aims at finding the numerical approximation of a classical Blasius flat plate problem using spectral collocation method. This technique is based on Chebyshev pseudospectral approach that involves the solution is approximated using Chebyshev ...

Relative asymptotics for orthogonal matrix polynomials
Linear Algebra and its Applications, 2012 In this paper we study sequences of matrix polynomials that satisfy a non-symmetric recurrence relation. To study this kind of sequences we use a vector interpretation of the matrix orthogonality. In the context of these sequences of matrix polynomials we introduce the concept of the generalized matrix Nevai class and we give the ratio asymptotics ...

Business Strategy and the Environment, EarlyView.ABSTRACT This study investigates companies' responses to energy efficiency policies, focusing on mandatory and voluntary regulations that create a complex landscape for businesses to navigate. Using a sample of 1473 firms across 29 European countries (2002–2018), we explore the impact of legislation on green redesign—operationalized through ...

Differential coefficients of orthogonal matrix polynomials
Journal of Computational and Applied Mathematics, 2006 The authors are interested in the following type of formulas: given a sequence of orthogonal polynomials \(\{P_n\}\), find the coefficients \(R_n(z)\) and \(S_n(z)\) in the expression \[ P_n'(z)=R_n(z) P_{n}(z)+S_n(z) P_{n-1}(z) \] (lowering operator), or with \(P_{n-1}\) in the right hand side replaced by \(P_{n+1}\) (raising operator).

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Global energy demand and environmental concerns have intensified the search for renewable and sustainable energy sources. This study thus, focuses on optimizing the transesterification process of waste cooking oil (WCO) using thermally activated basic oxygen furnace slag catalyst calcined at 850°C (BOF 850). The optimization and modelling were

An note on the maximization of matrix valued Hankel determinants with application [PDF]
In this note we consider the problem of maximizing the determinant of moment matrices of matrix measures. The maximizing matrix measure can be characterized explicitly by having equal (matrix valued) weights at the zeros of classical (one dimensional ...
