Operator Calculus of Quantized Operator [PDF]
Progress of Theoretical Physics, 1952 The notational ambiguities in Feynman's calculus are all remedied here by setting a more natural foundation of the ordered exponential operators, which will be called briefly "expansional" operators in this paper. The essential point to be stressed is that the pure exponential opErator is merely a special case of the more wider class of operators, i.e.,

FEBS Open Bio, EarlyView.Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

Bisymmetric and quasitrivial operations: characterizations and enumerations [PDF]
, 2018 We investigate the class of bisymmetric and quasitrivial binary operations on a given set $X$ and provide various characterizations of this class as well as the subclass of bisymmetric, quasitrivial, and order-preserving binary operations.

FEBS Open Bio, EarlyView.This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

The potential financial impact and influence of black economic empowerment (BEE) on private higher education institutions in South Africa: management alert [PDF]
Problems and Perspectives in Management, 2019 Education is considered an important pillar of economic development and a vital factor for nation building in post-1994 South Africa. Higher education (HE) is offered by government-subsidized universities and colleges, while there has been an increase in

Phase space contraction and quantum operations
, 2005 We give a criterion to differentiate between dissipative and diffusive quantum operations. It is based on the classical idea that dissipative processes contract volumes in phase space.

Digital twins to accelerate target identification and drug development for immune‐mediated disorders
FEBS Open Bio, EarlyView.Digital twins integrate patient‐derived molecular and clinical data into personalised computational models that simulate disease mechanisms. They enable rapid identification and validation of therapeutic targets, prediction of drug responses, and prioritisation of candidate interventions.

FEBS Open Bio, EarlyView.Chemotherapy side effects significantly impact cancer survivors' quality of life. Using protein levels in blood samples from breast cancer patients before and after 12 weeks of taxane treatment, we detected treatment‐dependent changes in calcium signaling and aging pathways associated with cancer recurrence.

Macroeconomic drivers affecting the foundry industry in South Africa
South African Journal of Economic and Management SciencesBackground: The problem addressed in the study reported on in this article is the decline of South Africa’s foundry industry. This industry is valuable in terms of job creation and a sustainable competitive advantage (SCA) strategy is required to sustain
