Network Structure and the Efficiency Gains from Mergers: Evidence from U.S. Freight Railroads

The RAND Journal of Economics, EarlyView.
ABSTRACT The trade‐off between market power and efficiency gains is central to antitrust analyses of mergers, but empirical evidence quantifying efficiencies remains limited. Using transaction‐level data from U.S. freight railroads (1985–2005), this article quantifies merger‐induced cost efficiencies, driven mainly by eliminating inter‐railroad ...

Progress on Control of Ultra-Low-Oxygen Content and Non-Metallic Inclusions in High Quality Bearing Steel

Teshugang, 2013
The ultra-low-oxygen content and low rating of inclusions are key indexes for high quality bearing steel. The influence factors on control of ultra-low-oxygen content and nonmetallic inclusions in high quality bearing steel are analyzed including removal

An Archaeometallurgical Investigation on Some Archaeological Metal Finds From the Sasanian Site of Jahāngir, Western Iran

Archaeometry, EarlyView.
ABSTRACT Twelve metal artifacts from recent excavations at the Sasanian archaeological site of Jahāngir in western Iran have been analyzed. These items include both decorative and utilitarian artifacts. The samples were examined using micro‐X‐ray fluorescence (μ‐XRF), scanning electron microscopy with energy‐dispersive X‐ray spectroscopy (SEM‐EDS), and

Does attachment removal damage enamel? Influence of adhesive, resin, and bur on surface integrity

European Journal of Oral Sciences, EarlyView.
Abstract To evaluate the combination of composites, adhesive systems, and burs considering artificial accelerated aging (AAA), influence enamel roughness and morphology after attachment removal. One hundred ninety‐two bovine enamel specimens were divided according to composite type (Transbond XT, flowable, bulk‐fill flowable), adhesive system (Single ...

Engineered surface strategies to manage dental implant‐related infections

Periodontology 2000, EarlyView.
Abstract When exposed to the oral environment, dental implants, like natural surfaces, become substrates for microbial adhesion and accumulation, often leading to implant‐related infections—one of the main causes of implant failure. These failures impose significant costs on patients, clinicians, and healthcare systems.

Emerging locally delivered antimicrobial and immunomodulatory approaches for the prevention/treatment of peri‐implant diseases

Periodontology 2000, EarlyView.
Abstract Peri‐implant diseases are dysbiosis‐mediated inflammatory disorders that occur in susceptible hosts. Antimicrobials and immunomodulatory agents therefore might be pertinent as adjunctive measures in the treatment of such disorders. The aim of this narrative review was to examine the existing evidence and assess the effectiveness of emerging ...
