The transfer functions of rocket nozzles [PDF]

open access: yes, 1952
The transfer function is defined as the fractional oscillating mass flow rate divided by the fractional sinusoidal pressure oscillation in the rocket combustion chamber. This is calculated as a function of the frequency of oscillation.

Quasiclassical Green function in an external field and small-angle scattering [PDF]

open access: yes, 1999
The quasiclassical Green functions of the Dirac and Klein-Gordon equations in the external electric field are obtained with the first correction taken into account.

Meromorphic functions that share four or three small functions with their difference operators

open access: yesAdvances in Difference Equations, 2019
In this paper, we prove that non-constant meromorphic functions of finite order and their difference operators are identical, if they share four small functions “IM”, or share two small functions and ∞ CM. Our results show that a conjecture posed by Chen–

Maturation of small nucleolar RNAs: from production to function

open access: yesRNA Biology, 2023
Small Nucleolar RNAs (snoRNAs) are an abundant group of non-coding RNAs with well-defined roles in ribosomal RNA processing, folding and chemical modification.

The Isgur-Wise Function in Small Velocity Limit

open access: yes, 1992
We discuss the Isgur-Wise function $\xi (y)$ in the small velocity (SV) limit within the QCD sum rule method. The behavior of $\xi (y)$ in the SV limit is sensitive to the particular form of the duality relations used to decontaminate the sum rule ...

Population and species neighbor identity impact trait–trait relationships and plant performance

open access: yesPopulation Ecology, EarlyView.
We evaluated how populations and species identity influence plant performance and trait outcomes in mixtures, and assessed trait variation among populations of two forb species native to the western United States (Dieteria canescens and Heterotheca villosa) following three interaction treatments (single‐population monoculture, two‐population mixture ...

Biogenesis, Trafficking, and Function of Small RNAs in Plants

open access: yesFrontiers in Plant Science, 2022
Small RNAs (sRNAs) encoded by plant genomes have received widespread attention because they can affect multiple biological processes. Different sRNAs that are synthesized in plant cells can move throughout the plants, transport to plant pathogens via ...

Nuclear Shadowing in the Structure Function $F_3(x)$ [PDF]

open access: yes, 1995
Nuclear modification of the structure function $F_3$ is investigated. Although it could be estimated in the medium and large $x$ regions from the nuclear structure function $F_2^A$, it is essentially unknown at small $x$.

Effects of chronic browsing on life‐history traits of an irruptive large herbivore population

open access: yesPopulation Ecology, EarlyView.
This study aimed to determine the relationship between diet quality, body mass, and size (hind foot length), and female reproduction and sought to identify the mechanism by which high density under severe food limitations is maintained. Our results demonstrated that sika deer introduced to Nakanoshima Island have maintained high densities through high ...

Entire functions that share a small function with their derivatives

open access: yesJournal of Mathematical Analysis and Applications, 2009
AbstractLet f be an entire function of finite order and a an entire function of order less than f's. If f−a and f′−a have the same zeros with the same multiplicities, then f′−a≡c(f−a) for some non-zero constant c.
