Reconstructing exact scalar-tensor cosmologies via conformal transformations

open access: yes, 2013
We propose a new reconstruction method for scalar--tensor gravity based on the use of conformal transformations. The new method allows the derivation of a set of interesting exact cosmological solutions in brans Dicke gravity as well as other extensions ...

DERIVATION ON SEVERAL RINGS

open access: yesBarekeng
Research on ring derivation is one of the studies that is quite popular among algebra lovers. The definition of the derivation on the ring is motivated by the derivation in calculus which has Leibniz's rule.

Development and validation of a LASSO-based prediction model for immunosuppressive medication nonadherence in kidney transplant recipients

open access: yesRenal Failure, 2023
Introduction To establish a prediction model to predict immunosuppressive medication (IM) nonadherence in kidney transplant recipients (KTRs) based on a combined theory framework.Methods This polycentric, cross-sectional study included 1191 KTRs from ...

An analysis of grammars by their derivation sets

open access: yesInformation and Control, 1974
One of the difficulties in the analysis of context-free grammars (and therefore languages) is the strong combinatorial nature of the mechanism. A measure of this complexity is suggested here. It involves labeling the productions and considering the sequences of labels that correspond to valid derivations.

A derivative in the setting of operator-valued measures [PDF]

open access: yesProceedings of the American Mathematical Society, 1973
There has been considerable recent development concerning integration of vector-valued functions with respect to operator-valued measures, including various Radon-Nikodym type theorems. This paper is concerned with obtaining an analytic definition of derivative which will act as an inverse operator for these integration processes.

Intravitreal GD2‐Specific Chimeric Antigen Receptor T‐Cell Therapy for Refractory Retinoblastoma

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Effective treatments for advanced, treatment‐resistant retinoblastoma (RB) remain limited. GD2‐specific chimeric antigen receptor (CAR) T cells show potent antitumor activity with minimal toxicity but have not previously been evaluated in RB.

Proton-electron mass ratio from HD$^+$ revisited

open access: yes, 2017
We present a new derivation of the proton-electron mass ratio from the hydrogen molecular ion, HD$^+$. The derivation entails the adjustment of the mass ratio in highly precise theory so as to reproduce accurately measured ro-vibrational frequencies ...

On a Special Subclass of the Set of Derivatives

open access: yesReal Analysis Exchange, 2007
We deal with the class of functions defined as a sum of a uniformly convergent series of functions continuous both on a closed set and on its complement. Such functions are mentioned in the literature, e.g., [1], [2], [3], [4].$ We investigate the particular class of derivatives.

Pediatric Oncology Nursing Competencies in Latin America and the Caribbean: A Scoping Review to Inform Practice, Education, and Research

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Nurses are central to cancer care for children and adolescents, yet no comprehensive synthesis has defined essential core competencies for pediatric oncology nursing (PON) practice internationally, particularly in Latin America and the Caribbean (LAC).
