Feasibility study for transforming spectral and instrumental artifacts for multivariate calibration maintenance.

Applied spectroscopy

Ottaway J, Kalivas JH.
PMID: 25664837
Appl Spectrosc. 2015 Mar;69(3):407-16. doi: 10.1366/14-07651. Epub 2015 Feb 01.

Frequently, a spectral-based multivariate calibration model formed on a particular instrument (primary) needs to predict samples measured on other (secondary) instruments of the same spectral type. This situation is often referred to as calibration maintenance or transfer. A new...

Characterization of the frequency stability of frequency-hopping sources.

IEEE transactions on ultrasonics, ferroelectrics, and frequency control

Kalivas GA, Harrison RG.
PMID: 18267604
IEEE Trans Ultrason Ferroelectr Freq Control. 1991;38(5):429-35. doi: 10.1109/58.84287.

A method that applies time-domain stability measures, hitherto used only in the context of fixed-frequency sources, to the characterization of frequency-hopped sources is introduced. This method has been successfully applied to the testing of a novel practical frequency-hopping synthesizer....

Acousto-optic matrix-matrix multiplier.

Optics letters

Kalivas DS, Albanese G, Sawchuk AA.
PMID: 19745876
Opt Lett. 1988 Apr 01;13(4):291-3. doi: 10.1364/ol.13.000291.

A new architecture for an optical matrix-matrix multiplier is presented. It is based on the beam-modulation and Its parallel structure makes it very fast. Some physical limitations are discussed.

A role for glutamate transmission in addiction to psychostimulants.

Addiction biology

Kalivas PW.
PMID: 20575849
Addict Biol. 2000 Jul 01;5(3):325-9. doi: 10.1111/j.1369-1600.2000.tb00199.x.

Abstract Psychostimulant addiction results in the emergence of undesirable behaviors such as drug craving and paranoia. Using animal models of addiction the neurobiological substrates mediating these behaviors have been examined. Studies have focused on cellular adaptations within the motive...

Spectral multivariate calibration with wavelength selection using variants of Tikhonov regularization.

Applied spectroscopy

Ottaway J, Kalivas JH, Andries E.
PMID: 21144157
Appl Spectrosc. 2010 Dec;64(12):1388-95. doi: 10.1366/000370210793561655.

Tikhonov regularization (TR) is a general method that can be used to form a multivariate calibration model and numerous variants of it exist, including ridge regression (RR). This paper reports on the unique flexibility of TR to form a...

Polyvinyl alcohol-montmorillonite composites for water purification: Analysis of clay mineral cation exchange and composite particle synthesis.

Polyhedron

Brown K, Mendoza M, Tinsley T, Bee-DiGregorio MY, Bible M, Brooks JL, Colorado M, Esenther J, Farag A, Gill R, Kalivas EN, Lara R, Lutz A, Nazaire J, Rasines Mazo A, Rodriguez RS, Schwabacher JC, Zestos AG, Hartings MR, Fox DM.

Polyhedron. 2021 Sep 01;205. doi: 10.1016/j.poly.2021.115297. Epub 2021 May 29.

Municipal and residential water purification rely heavily on activated carbon (AC), but regeneration of AC is costly and cannot be performed at the point-of-use. Clay minerals (CMs) comprise a class of naturally abundant materials with known capacities for analyte...

Extrasynaptic therapeutic targets in substance use and stress disorders.

Trends in pharmacological sciences

Hodebourg R, Kalivas PW, Kruyer A.
PMID: 34753604
Trends Pharmacol Sci. 2022 Jan;43(1):56-68. doi: 10.1016/j.tips.2021.10.006. Epub 2021 Nov 06.

Treatments for substance use and stress disorders are based on ameliorating behavioral symptoms, not on reversing the synaptic pathology that has the potential to cure disorders. This failing arises in part from a research focus on how pre- and...

Nutrients in the form of fertilizers and/or other additives such as amino acids, dramatically influence plant development and growth, plant nutrient composition and the level of soil pollution. Moreover, the treatment of soil microbiota is emerging as a new...

Understanding Addiction Using Animal Models.
