Achieving useful data analytics for marketing: Discrepancies in information quality for producers and users of information

open access: yesBusiness Research Quarterly, 2023
This study proposes as a key cause of the high failure rates in the implementation of analytical projects for marketing decisions, the discrepancy in the information quality (DIQ) perceived between producers (information technology [IT]) and users ...

GMOR-like relation in IR-conformal gauge theories

open access: yes, 2011
A generalization of the GMOR relation to the case of infrared-conformal gauge theories is discussed. The starting point is the chiral Ward identity connecting the isovector pseudoscalar susceptibility to the chiral condensate, in a mass-deformed theory ...

Electrons and X‐rays for diffraction and imaging

open access: yesActa Crystallographica Section D, EarlyView.
The use of X‐rays and electrons for diffraction and imaging of soft biological samples is compared.A comparison is provided between the use of electrons and X‐rays for collecting diffraction data from small protein crystals and imaging data from cells and tissues.

Effect of extension of the heparin binding pocket on the structure, stability, and cell proliferation activity of the human acidic fibroblast growth factor

open access: yesBiochemistry and Biophysics Reports, 2018
Acidic human fibroblast growth factor (hFGF1) plays a key role in cell growth and proliferation. Activation of the cell surface FGF receptor is believed to involve the glycosaminoglycan, heparin.

Structures of variants of Escherichia coli flavodiiron‐type nitric oxide reductase reveal changes in the di‐iron site

open access: yesActa Crystallographica Section D, EarlyView.
Flavodiiron proteins (FDPs) are di‐iron enzymes that reduce NO and/or O2 with distinct substrate selectivity. We have produced E. coli FDP variants targeting second coordination‐sphere residues and determined their structures. Although the kinetics remained unchanged, the E.

Invisible Higgs and Scalar Dark Matter

open access: yes, 2011
In this proceeding, we show that when we combined WMAP and the most recent results of XENON100, the invisible width of the Higgs to scalar dark matter is negligible(

Damage‐limited resolution for X‐ray and electron microscopy of organic specimens

open access: yesActa Crystallographica Section D, EarlyView.
Analytical expressions for the damage‐limited resolution are developed and applied to X‐ray and electron imaging of beam‐sensitive specimens. The findings will guide future microscopy and instrument design.Analytical expressions for the damage‐limited resolution (DLR) are developed and applied to X‐ray and electron imaging of beam‐sensitive specimens ...

Are Hedonic Models Really Quality-Adjusted? The Role of Apartment Quality in Hedonic Models of Housing Rental Market

open access: yesReal Estate Management and Valuation
In micro-level data concerning the housing market, the apartment quality may be signaled via textual statements or the attached descriptions/photos. It may be done using hard information related to the easier-to-measure structural characteristics or soft

Symmetryless Dark Matter

open access: yes, 2011
It is appealing to stabilize dark matter by the same discrete symmetry that is used to explain the structure of quark and lepton mass matrices. However, to generate the observed fermion mixing patterns, any flavor symmetry must necessarily be broken ...
