Space and exclusion: does urban morphology play a part in social deprivation? [PDF]

, 2005
There is currently a growing interest in the spatial causes of poverty, particularly its persistence. This paper presents methodological innovations that have been developed for investigating the relationship between physical segregation and economic ...

When Does Top Management Team Diversity Matter in Large Organizations?

Journal of Organizational Behavior, EarlyView.
ABSTRACT Top management teams (TMTs) drive strategic leadership, but there is little clarity on when the composition of these upper echelons most impacts organization performance. Drawing from the categorization‐elaboration model, we study an 18‐year sample of approximately 4500 organizations and over 32 000 executives and find a positive relationship ...

Effects of Substrate Bias Voltages on Tribological Properties of DLC Films under Rolling-Sliding Contact with High Pressure

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2012
In the present paper, tribological properties of DLC films deposited by UBM sputtering were investigated by rolling contact friction tests under approximately 2.86GPa of high contact pressure.

Investigation of diamond biocompatible coatings for medical implants [PDF]

, 2015
Despite the advantages of diamond-like carbon fi lms that are used as wear-resistant coatings for implants, they may have a number of disadvantages such as the high level of internal tension, low adhesive durability and high sensitivity to environment ...

Clear Evidence for Intranight Optical Variability in Radio-quiet Quasars [PDF]

, 2003
We present new clues to the problem of the radio loudness dichotomy arising from an extensive search for intranight optical variability in seven sets of optically luminous radio-quiet quasars and (radio-loud) BL Lacertae objects, which are matched in ...

Interrater reliability in pediatric high‐resolution anorectal manometry recordings

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives High‐resolution anorectal manometry (HR‐ARM) is a diagnostic test assessing anorectal neuromuscular function in children with constipation and/or fecal incontinence. Interrater reliability of HR‐ARM in children has not been previously studied. The aim of this study was to assess the interrater reliability of pediatric HR‐ARM studies.

Bridge expansion joint in road transition curve: effects assessment on heavy vehicles [PDF]

, 2017
Properly-designed road surfaces provide a durable surface on which traffic can pass smoothly and safely. In fact, the main causes that determine the structural decay of the pavement and its parts are the traffic loads.

Tailoring Spatial Correlations With Quantum Interference

Laser &Photonics Reviews, EarlyView.
Imposing spatial structure on interfering photons fundamentally reshapes their correlations. By controlling the mutual distinguishability of two photons, we write and edit these correlations, encoding information that is invisible to conventional intensity measurements and revealed only through their joint behavior.

Cobalt‐Doped Diamond‐Like Carbon Coatings Combined With Functionalised Polymers for Enhanced Tribological Performance

Lubrication Science, EarlyView.
ABSTRACT In recent years, doped diamond‐like carbon (DLC) coatings combined with functionalised copolymers have gained attention as a lubrication concept. While silicon‐doped DLC has been widely studied, polymer‐assisted lubrication on other doped DLC systems remains less explored.

Diamondlike carbon protective coatings for optical windows [PDF]

Diamondlike carbon (DLC) films were deposited on infrared transmitting optical windows and were evaluated as protective coatings for these windows exposed to particle and rain erosion. The DLC films were deposited on zinc selenide (ZnSe) and zinc sulfide
