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.,

A Survey on Operator Monotonicity, Operator Convexity, and Operator Means [PDF]

International Journal of Analysis, 2015
This paper is an expository devoted to an important class of real-valued functions introduced by Löwner, namely, operator monotone functions. This concept is closely related to operator convex/concave functions. Various characterizations for such functions are given from the viewpoint of differential analysis in terms of matrix of divided differences ...

A Cre‐dependent lentiviral vector for neuron subtype‐specific expression of large proteins

FEBS Letters, EarlyView.
We designed a versatile and modular lentivector comprising a Cre‐dependent switch and self‐cleaving 2A peptide and tested it for co‐expression of GFP and a 2.8 kb gene of interest (GOI) in mouse cortical parvalbumin (PV+) interneurons and midbrain dopamine (TH+) neurons.

Invasive alien plants at Capraia Island (Italy): distribution and threats to Natura 2000 habitats [PDF]

Plant Sociology
Island ecosystems face significant threats from biological invasions due to their unique biomes. In over a quarter of these ecosystems, the number of alien plants surpasses the total count of native ones, leading to notable impacts.

On Unbounded Composition Operators in $L^2$-Spaces

, 2012
Fundamental properties of unbounded composition operators in $L^2$-spaces are studied. Characterizations of normal and quasinormal composition operators are provided. Formally normal composition operators are shown to be normal.

Light-ray operators in conformal field theory [PDF]

Journal of High Energy Physics, 2018
A bstractWe argue that every CFT contains light-ray operators labeled by a continuous spin J. When J is a positive integer, light-ray operators become integrals of local operators over a null line.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Baxter operators for arbitrary spin

, 2011
We construct Baxter operators for the homogeneous closed $\mathrm{XXX}$ spin chain with the quantum space carrying infinite or finite dimensional $s\ell_2$ representations.

Some q‐rung orthopair fuzzy Heronian mean operators in multiple attribute decision making

International Journal of Intelligent Systems, 2018
The generalized Heronian mean and geometric Heronian mean operators provide two aggregation operators that consider the interdependent phenomena among the aggregated arguments.

Why emerging leaders should focus on being good postdoctoral supervisors

FEBS Letters, EarlyView.
Swamped with work and suddenly a new student is waiting at your doorstep for supervision? Great—this is your chance! In this article, we share tips on how postdocs can strengthen their leadership skills while supervising students. This image has been created using DALL·E. Many postdocs work as leaders later in their career.
