Executive Summary There are many sources of data integrity errors within storage networks and devices. The T10 (SCSI) standards committee developed the Data Integrity Field specification (DIF) to provide protection within storage disks by extending the size of disk sectors by 8 bytes, which contain protection information, including a 16 bit CRC. This integrity metadata enables corrupted write a...

the purpose of this study was to detect differentially functioning items in the university of tehran english proficiency test (utept) which is a high stake test of english developed and administered by the language testing centre of the university of tehran. this paper is based on the answers of 400 test takers to the test. all participants earned a master degree either in humanities or science...

Difenoconazole (DIF) is a representative variety of broad-spectrum triazole fungicides and liposoluble pesticides. However, the water solubility DIF so poor that its application limited in plant protection. In addition, conventional formulations always contain abundant organic solvents, which may cause pollution environment. this study, two DIF/cyclodextrins (CDs) inclusion complexes (ICs) were...

Differentiation-inducing factor-3 (DIF-3), found in the cellular slime mold Dictyostelium discoideum, and its derivatives, such as butoxy-DIF-3 (Bu-DIF-3), are potent anti-tumor agents. To investigate the activity of DIF-like molecules in tumor cells, we recently synthesized a green fluorescent DIF-3 derivative, BODIPY-DIF-3G, and analyzed its bioactivity and cellular localization. In this stud...

The present study examines bias factors which might grant a relative advantage to native Israelis over groups of immigrants in a mathematics achievement test administered to fifth grade students. The bias factor analysis process, aided by quantitative and qualitative data gathering methods, comprised three phases: (1) Using a psychometric procedure called DIF (Differential Item Functioning) to ...

Differentiation-inducing factor-1 [1-(3,5-dichloro-2,6-dihydroxy-4-methoxyphenyl)hexan-1-one (DIF-1)] is an important regulator of cell differentiation and chemotaxis in the development of the cellular slime mold Dictyostelium discoideum However, the entire signaling pathways downstream of DIF-1 remain to be elucidated. To characterize DIF-1 and its potential receptor(s), we synthesized two flu...

BACKGROUND Rasch analysis with a focus on Differential Item Functioning (DIF) is increasingly used for examination of psychometric properties of health outcome measures. To take account of DIF in order to retain precision of measurement, split of DIF-items into separate sample specific items has become a frequently used technique. The purpose of the paper is to present and summarise recent adva...
