Projective Techniques and Functional Integration [PDF]

open access: yes, 1994
A general framework for integration over certain infinite dimensional spaces is first developed using projective limits of a projective family of compact Hausdorff spaces.

Functions and integrals [PDF]

open access: yesTransactions of the American Mathematical Society, 1972
In §2 a mapping of nonnegative functions is defined to be an integral if it has the following properties: I ( f ) ⩾ 0 , I ( f ) > ∞ I(f) \geqslant 0,I(f) > \infty for some f f , if f ⩽ g f ...

Functional determinants by contour integration methods [PDF]

open access: yes, 2003
We present a simple and accessible method which uses contour integration methods to derive formulae for functional determinants. To make the presentation as clear as possible, the general idea is first illustrated on the simplest case: a second order ...

Integrals involvingE-functions [PDF]

open access: yesMathematische Zeitschrift, 1958
1. Introductory. The following two integrals will be established in § 2.If m is a positive integer, if p ≧ q + 1 and if R(ar+kt) > 0 (r = 1, 2,…, p, t = 1, 2,…, m),where co is 1 or e±in according as m is even or odd, the dash denotes that the factor sin (k,–k,)π does not appear and the asterisk that the parameter kt–kt + 1 is omitted.

A Preliminary Examination of Nicotine-Free Electronic Cigarette Use During Cessation From Combustible Cigarettes

open access: yesFrontiers in Psychiatry, 2019
Despite the availability of smoking cessation strategies, smoking cue-induced craving remains a relatively untreated relapse risk factor. Utilizing nicotine-free electronic cigarettes (e-cigarettes) to extinguish the motivational influence of smoking ...

Modular Multifunctional Composite Structure for CubeSat Applications: Preliminary Design and Structural Analysis

open access: yesAerospace, 2020
CubeSats usually adopt aluminum alloys for primary structures, and a number of studies exist on Carbon Fiber Reinforced Plastic (CFRP) primary structures.

Propofol Induction Reduces the Capacity for Neural Information Integration: Implications for the Mechanism of Consciousness and General Anesthesia [PDF]

open access: yes, 2008
The cognitive unbinding paradigm suggests that the synthesis of cognitive information is attenuated by general anesthesia. Here, we investigated the functional organization of brain activities in the conscious and anesthetized states, based on ...

Framing major prebiotic transitions as stages of protocell development: three challenges for origins-of-life research

open access: yesBeilstein Journal of Organic Chemistry, 2017
Conceiving the process of biogenesis as the evolutionary development of highly dynamic and integrated protocell populations provides the most appropriate framework to address the difficult problem of how prebiotic chemistry bridged the gap to full ...

Ultraviolet Renormalization of the Nelson Hamiltonian through Functional Integration [PDF]

open access: yes, 2013
Starting from the N-particle Nelson Hamiltonian defined by imposing an ultraviolet cutoff, we perform ultraviolet renormalization by showing that in the zero cutoff limit a self-adjoint operator exists after a logarithmically divergent term is subtracted

Termite-inspired metamaterials for flow-active building envelopes

open access: yesFrontiers in Materials, 2023
In this article we investigate the performative potential of reticulated tunnel networks to act as drivers for selective airflows in building envelopes and thereby facilitate semi-passive climate regulation.
