[18F]BIBD-181: A Novel Positron Emission Tomography Tracer Specific for Synaptic Vesicle Glycoprotein 2A

open access: yesACS Medicinal Chemistry Letters, 2022
Dysfunction or decreased expression of synaptic vesicle glycoprotein 2A (SV2A) is closely related to the progression of neurodegenerative diseases and psychiatric disorders. The development of positron emission tomography (PET) tracers targeting SV2A can

A new code construction with zero cross correlation based on BIBD

open access: yesOptik, 2013
International audienceThis paper presents a newly constructed zero cross correlation code (ZCC) which is based on BIBD (balanced incomplete block design) code. The ZCC (C, w) code is a family of binary sequences of length C and constant Hamming-weight w.

A Conjecture about BIBDs

Communications in Statistics - Simulation and Computation, 2014
The conjecture:“If the case (v,k) = (8, 3) is the only one where the trivial balanced incomplete block design (BIBD) is elementary” is formulated. It is supported by the theorem:TheoremThe conjecture is correct if at least one of the following conditions holds:v 8 if v is prime or a prime power.

BIBD's with block-size seven

open access: yesDiscrete Mathematics, 1989
This paper is an addition to \textit{H. Hanani} [Balanced incomplete block designs and related designs, Discrete Math. 11, 255-269 (1975; Zbl 0361.62067)] and uses the numbering system from the preceding paper. The author proves that the obvious necessary conditions for the existence of a BIBD with \(k=7\) and \(\lambda =3\) and 21 are sufficient, with

Fault-tolerant BIBD networks

[1988] The Eighteenth International Symposium on Fault-Tolerant Computing. Digest of Papers, 2003
The use of multiple buses can improve both the fault tolerance and performance of local area computer networks. Existing schemes either depend on active components for full connectivity or can experience decreased performance as many hosts attempt to access one bus. An architecture class based on balanced incomplete block designs (BIBDs) is proposed to

On the E-Optimality of Truncated BIBD

Calcutta Statistical Association Bulletin, 1985
It is shown that if some blocks are deleted from a BIBD, then under certain conditions on the parameters, the resulting design is E-optimal.
