Peer review is fundamental to science as we know it, but is also a source of delay in getting discoveries communicated to
the world. Researchers have investigated the effectiveness and bias of various forms of peer review, but little attention
has been paid to the relationships among journal reputation, rejection rate, number of submissions received and time from
submission to acceptance. In 22 ecology/interdisciplinary journals for which data could be retrieved, higher impact factor
is positively associated with the number of submissions. However, higher impact factor journals tend to be significantly quicker
in moving from submission to acceptance so that journals which receive more submissions are not those which take longer to
get them through the peer review and revision processes. Rejection rates are remarkably high throughout the journals analyzed,
but tend to increase with increasing impact factor and with number of submissions. Plausible causes and consequences of these
relationships for journals, authors and peer reviewers are discussed.
This article presents an exploratory analysis of publication delays in the science field. Publication delay is defined as
the time period between submission and publication of an article for a scientific journal. We obtained a first indication
that these delays are longer with regard to journals in the fields of mathematics and technical sciences than they are in
other fields of science. We suggest the use of data on publication delays in the analysis of the effects of electronic publishing
on reference/citation patterns. A preliminary analysis on a small sample suggests that—under rather strict assumptions—the
cited half-life of references may be reduced with a factor of about 2 if publication delays decrease radically.
We establish the existence of mild solutions and periodic mild solutions for a class of abstract first-order non-autonomous
neutral functional differential equations with infinite delay in a Banach space.

A delayed neutron counting system has been implemented at the HANARO research reactor in 2007. Thermal neutron flux measured
at the NAA #2 irradiation hole coupled to the delayed counting system, was higher than 3 × 1013 n cm−2 s−1. The delayed neutron counting system is composed of 18 3He detectors which are divided into three groups with six detectors and the collected signals of each group are processed
to a digital signal. The count numbers were measured with the uranium mass by using NIST SRMs under fixed analytical condition
and their correlation could be determined. Finally, delayed neutron activation analysis has been carried out for the determination
of uranium mass fraction in the collected environmental samples.
The inter-citation journal group is defined as a group of journals with inter-citation relations. In this paper, according
to the 2003 JCR, an inter-citation relation matrix of 10 medical journals is established. Based on the transfer function model
of the disturbed citing process, the calculation formula of journal impact factor disturbed by publication delays of certain
journal in the group is deduced and a changing process of every journal's impact factor caused by the increase of each journal's
average publication delay is simulated. In the inter-citation journal group, when a journal's publication delay increase,
impact factors of all journals will be decreased and rankings of journals according to the impact factor may be changed. The
closer a citation relation between two journals, the stronger the interaction of them and the larger the decrease of their
impact factors caused by the increase of their publication delays.
An automated delayed neutron counting (DNC) system has been developed at the Royal Military College of Canada (RMC) to enhance
nuclear forensics capabilities pertaining to special nuclear material analysis. The system utilises the SLOWPOKE-2 Facility
at RMC as a neutron source and 3He detectors. System control and data acquisition occur through a LabVIEW platform. The time dependent count rate of the delayed
neutron production has been examined for 235U, using certified reference materials. Experimental validation according to ISO 17025 protocols suggests typical errors and
precision of −3.6 and 3.1%, respectively, and a detection limit of 0.26 μg 235U.
The main concern of this paper is to study the dynamic of a ratio dependent predator-prey system with diffusion and delay.
Concretely, we prove that when the system of PDE is persistent the nontrivial equilibrium is globally asymptotically stable.
In this paper some predictions about some delayed neutron precursor yields are presented. The predictions are applied for certain actinides with some special interest in the nuclear energy field. The predictions are based on correlations which might be related to the cluster structure of the nucleus.
We present new oscillation criteria for the second order nonlinear neutral delay differential equation [y(t)-py(t-τ)]''+ q(t)yλ(g(t)) sgn y(g(t)) = 0, t ≧ t0. Our results solve an open problem posed by James S.W . Wong . The relevance of our results becomes clear due to a carefully
