Proof of Cramer’s rule with Dirac delta function
European Journal of Physics, 2020 Abstract We present a new proof of Cramer’s rule by interpreting a system of linear equations as a transformation of n-dimensional Cartesian-coordinate vectors. To find the solution, we carry out the inverse transformation by convolving the original coordinate vector with Dirac delta functions and changing integration variables from the ...

Applications in Plant Sciences, EarlyView.Abstract Premise Applied ecology can significantly influence policy decisions on environmental issues. Therefore, research in this field should be as transparent and reproducible as possible. Existing expertise from a broad range of disciplines should also be integrated into ecological research to allow researchers to maximize understanding of complex ...

Autism Research, EarlyView.ABSTRACT Autism spectrum disorder (ASD) is characterized by alterations in social understanding and self‐related experience that overlap with broader dimensions of psychosocial vulnerability. These domains are tightly interconnected, motivating the use of analytic approaches that can capture their organization as complex associations rather than as ...

Autism Research, EarlyView.ABSTRACT High levels of parental stress and psychological inflexibility are common among caregivers raising children with neurodevelopmental disabilities. Navigator ACT is a group‐based treatment developed to increase psychological flexibility and reduce the impact of stress among parents of children with various disabilities (e.g., autism spectrum ...

The Unique Roles of Executive Function in Co‐Occurring Psychopathologies in Autism
Autism Research, EarlyView.ABSTRACT Children with autism spectrum disorder (ASD) often experience co‐occurring psychiatric conditions, such as anxiety and attention‐deficit/hyperactivity disorder (ADHD), which significantly impair daily functioning. However, the underlying mechanisms linking these conditions to core ASD features remain poorly understood.

British Journal of Clinical Pharmacology, EarlyView.Aims This study looks at the status of the same drugs conditionally approved by the Food and Drug Administration and Health Canada for the same oncology indication. Methods Lists of oncology drugs with a conditional approval from the Food and Drug Administration and Health Canada were generated and drug pairs with the same indication were matched ...

British Journal of Clinical Pharmacology, EarlyView.Introduction Introduction Reporting adverse drug reactions (ADRs) is essential for detecting drug risks. Despite legal obligations in Switzerland, underreporting remains an issue. This study assessed practice, knowledge and attitudes towards the spontaneous ADR reporting system among physicians and pharmacists.

Maple TransactionsCramer's Rule is a well known result giving the solutions of the matrix equation Ax=b for nonsingular matrices A. This rule is quite popular with students since it gives a concise concrete expression and a deterministic method for solving systems of equations. We consider the often overlooked "cost" of calculating solutions using Cramer's Rule.

Old and new proofs of Cramer's rule
Applied Mathematical Sciences, 2014 In spite of its high computational cost, Cramer’s Rule for solving systems of linear equations is of historical and theoretical importance. In this paper we list six dierent proofs of it, the last of which has not apparently been published elsewhere. A discussion on their educational value and the tools involved is also included.

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