Improved Propagation and Growing Techniques for Oleander Nursery Production

open access: yesHorticulturae, 2019
In the first trial, we examined rooting of stem cuttings in relation to number of nodes and indole-3-butyric acid (IBA) treatment in several Nerium oleander clones grown in Sicily.

Forced patterns near a Turing-Hopf bifurcation

open access: yes, 2009
We study time-periodic forcing of spatially-extended patterns near a Turing-Hopf bifurcation point. A symmetry-based normal form analysis yields several predictions, including that (i) weak forcing near the intrinsic Hopf frequency enhances or suppresses

Integer-Forcing Linear Receivers [PDF]

open access: yes, 2014
Linear receivers are often used to reduce the implementation complexity of multiple-antenna systems. In a traditional linear receiver architecture, the receive antennas are used to separate out the codewords sent by each transmit antenna, which can then ...

Pleading as Information-Forcing [PDF]

open access: yes, 2012
Academics, judges, and practitioners have devoted much attention to the potential impact of the federal pleading standards announced in Ashcroft v. Iqbal, 556 U.S. 662 (2009), and Bell Atlantic Corp. v. Twombly, 550 U.S. 544 (2007).

A Model in Which Well-Orderings of the Reals First Appear at a Given Projective Level, Part III—The Case of Second-Order PA

open access: yesMathematics, 2023
A model of set theory ZFC is defined in our recent research, in which, for a given n≥3, (An) there exists a good lightface Δn1 well-ordering of the reals, but (Bn) no well-orderings of the reals (not necessarily good) exist in the previous class Δn−11 ...

Characterizations of pretameness and the Ord-cc

open access: yes, 2017
It is well known that pretameness implies the forcing theorem, and that pretameness is characterized by the preservation of the axioms of $\mathsf{ZF}^-$, that is $\mathsf{ZF}$ without the power set axiom, or equivalently, by the preservation of the ...

Wave-unlocking transition in resonantly coupled complex Ginzburg-Landau equations [PDF]

open access: yes, 1996
We study the effect of spatial frequency-forcing on standing-wave solutions of coupled complex Ginzburg-Landau equations. The model considered describes several situations of nonlinear counterpropagating waves and also of the dynamics of polarized light ...

A Generic Model in Which the Russell-Nontypical Sets Satisfy ZFC Strictly between HOD and the Universe

open access: yesMathematics, 2022
The notion of ordinal definability and the related notions of ordinal definable sets (class OD) and hereditarily ordinal definable sets (class HOD) belong to the key concepts of modern set theory. Recent studies have discovered more general types of sets,

Usefulness of japanese bunching onion (Allium fistulosum L.) for forcing in greenhouse

open access: yesActa Agrobotanica, 2012
The purpose of this work was the evaluation of yielding and the content of some chemical ingredients of Japanese bunching onion yield obtained from forcing in greenhouse conditions.

A Model in Which Well-Orderings of the Reals First Appear at a Given Projective Level, Part II

open access: yesMathematics, 2023
We consider the problem of the existence of well-orderings of the reals, definable at a certain level of the projective hierarchy. This research is motivated by the modern development of descriptive set theory.
