• #### Generalized likelihood ratio detection for fMRI using complex data ﻿

(1999-04-20)
The majority of fMRI studies obtain functional information using statistical tests based on the magnitude image reconstructions. Recently, a complex correlation (CC) test was proposed based on teh complex image data in ...
• #### GENERALIZED REPLACEMENT IN ITERATIVE RESTORATION ALGORITHMS ﻿

(1983)
A new formulation of an iterative restoration algorithm is presented in this dissertation for the solution of noisy, non-linear restoration problems. The constraints and distortions are assumed to be known and are modeled ...

(1970-04)
• #### Generation and characterization of femtosecond vacuum ultraviolet pulses ﻿

(1994)
High power femtosecond VUV/XUV pulses covering new spectral regions have been generated through nonlinear interaction of a femtosecond KrF laser with xenon and argon. Conversion efficiencies as high as 10$\sp{-3}$ have ...

(1965)

(1978)
• #### Generation of broad bandwidth UV pulses via sum frequency mixing ﻿

(1994)
Focusing effects on phase front curvature are important in determining the band-width generated in the near vacuum ultraviolet by sum frequency mixing of ultrashort pulses. Noncollinear sum frequency mixing is utilized to ...
• #### Generation of diffraction-free beams for applications in optical microlithography ﻿

(1997-03-01)
A new concept based on a Fabry–Perot interferometer for the generation of nondiffracting Bessel beams is described and proposed for potential applications in microlithography such as the fabrication of small isolated ...
• #### Generation of nearly nondiffracting Bessel beams with a Fabry–Perot interferometer ﻿

(1997-11-01)
A new concept for generating zero-order Bessel beams was studied theoretically. The spatial intensity distribution was calculated numerically using a wave optics model. Approximate analytical expressions were derived to ...
• #### Generation of osteochondral tissue constructs with chondrogenically and osteogenically predifferentiated mesenchymal stem cells encapsulated in bilayered hydrogels ﻿

(2014)
This study investigated the ability of chondrogenic and osteogenic predifferentiation of mesenchymal stem cells (MSCs) to play a role in the development of osteochondral tissue constructs using injectable bilayered ...
• #### Generation of radical anions by decomposition of azo compounds ﻿

(1996)
A new method for the generation of radical anions has been developed. Homolytic cleavage of an azo compound bearing a negative charge $\beta$ to the N=N linkage creates a radical anion intermediate. The radical anions so ...
• #### Generations at Work: Don't Throw the Baby Out With the Bathwater ﻿

(2015)
Costanza and Finkelstein (2015) are correct to highlight the dangers of using generationally based stereotypes in organizations. Although popular, these stereotypes are related to a stigmatization based on group membership ...
• #### Genericity and Robustness of Full Surplus Extraction ﻿

(2013)
We study whether priors that admit full surplus extraction (FSE) are generic, an issue that becomes a gauge to evaluate the validity of the current mechanism design paradigm. We consider the space of priors on the universal ...
• #### Genes expressed during oogenesis in Calliphora erythrocephala and Drosophila melanogaster ﻿

(1990)
We were interested in identifying genes in the dipteran flies Calliphora erythrocephala and Drosophila melanogaster with a role in oogenesis and early embryogenesis. A biochemical screen was used to complement the extensive ...
• #### Genes, organelles, and molecules that influence plant development through auxin regulation ﻿

(2005)
Humankind depends on plants to harvest solar energy and convert it into accessible chemical energy. With booming human population growth and diminishing availability of arable land, understanding plant development is ...

(1965)
• #### Genetic algorithm tuning of a fuzzy logic controller for a dynamic system ﻿

(1995)
This thesis describes the use of the genetic algorithm to facilitate the design process of a fuzzy logic based controller. The basic mechanics of both the fuzzy logic control system and the genetic algorithm are presented ...
• #### Genetic analyses of auxin metabolism and of the transition to flowering in the model plant Arabidopsis thaliana ﻿

(2000)
The auxins are an important class of plant hormones involved in many aspects of plant development The most common naturally occurring auxin is indole-3-acetic acid, or IAA. In Arabidopsis, up to 95% of the IAA pool is found ...
• #### Genetic analysis of auxin homeostasis: Conjugate sensitivity and auxin supersensitivity ﻿

(2002)
Through their regulation of gene expression and cell growth, auxins affect many aspects of plant growth and development. One mechanism through which auxin homeostasis is achieved is by conjugating indole-3-acetic acid (IAA, ...
• #### Genetic analysis of IAA-conjugate sensitivity in Arabidopsis thaliana: Hydrolysis, transcriptional regulation, and metal homeostasis ﻿

(2005)
Auxins are hormones important for numerous processes throughout plant development. Plants use several mechanisms to regulate levels of the auxin indole-3-acetic acid (IAA), including the formation and hydrolysis of ...
