Modeling and parameter estimation for fractional large‐scale interconnected Hammerstein systems

open access: yesAsian Journal of Control, EarlyView.
Abstract This paper addresses the challenge of modeling and identifying large‐scale interconnected systems exhibiting memory effects, hereditary properties, and non‐local interactions. We propose a fractional‐order extension of the Hammerstein architecture that incorporates Grünwald–Letnikov operators to capture complex dynamics through multiple ...

Performance improvement of discrete‐time linear‐quadratic regulators applied to uncertain linear systems using the Tikhonov regularization method

open access: yesAsian Journal of Control, EarlyView.
Abstract The linear‐quadratic regulator (LQR) problem of optimal control of an uncertain discrete‐time linear system (DTLS) is revisited in this paper from the perspective of Tikhonov regularization. We show that an optimally chosen regularization parameter reduces, compared to the classical LQR, the values of a scalar error function, as well as the ...

Strong nonlinear functional-differential variational inequalities: problems without initial conditions

open access: yesFrontiers in Applied Mathematics and Statistics
Problems without initial conditions for evolution equations and variational inequalities appear in the modeling of different non-stationary processes within many fields of science, such as ecology, economics, physics, cybernetics, etc., if these ...

Advanced therapy medicinal products (ATMPs) – An analysis of the global regulatory status

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Abstract Background A rapid progress in the development of advanced therapy medicinal products (ATMPs) has taken place over the past decades. The ATMPs hold great potential but face challenges in the clinical development and the regulatory process.

Listening to young children with disabilities: Experiences of quality in mainstream primary education

open access: yesBritish Educational Research Journal, EarlyView.
Abstract All children should have access to quality education through a child‐centred pedagogy. An inclusive, child‐centred pedagogy uses a strength‐based view of children that recognises each child as unique and competent, providing children with multiple opportunities to explore and learn at their own pace.

Ethnicity and the surgical management of early invasive breast cancer in over 164 000 women

open access: yesBJS (British Journal of Surgery), EarlyView., 2020
This large national study examined in detail the patterns in surgical management of early breast cancer in women of different ethnicities. Allowing for different patterns of age and stage at presentation, the surgical management of early breast cancer was similar in all women, regardless of ethnicity. All treated the same Background Limited information

Activism as education in and through the youth climate justice movement

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Young people worldwide are increasingly participating in a global movement for climate justice, yet to date, little research has examined how youth climate justice activists conceive of and experience activism as education. The present study used in‐depth, semi‐structured interviews with 16 US climate justice activists (aged 15–17) to address ...
