today, the global business environment compels enterprises to consider rest of the world in their competitive strategy analysis where firms ignore external factors such as economic trends, competitive positions or technology advancement in other countries. while going truly global with supply chain management, a company develops product in the united states, produce in india and trade in europe...

Experimental studies of the cultural evolution of language have focused on how constraints on learning and communication drive emergence of linguistic structure. Yet language is typically transmitted by experts who adjust the input in ways that facilitates learning by novices, e.g. through child-directed speech. Using iterated language learning of binary auditory sequences, we explored how lang...

Along with proving the sufficiency of the Qur’ān for the extraction of the religious knowledge, the Qur’ānists have doubted the authenticity and the authoritativeness of the sunna and Ḥadīth. One of their reasons for the inauthenticity of the sunna is the inefficiency of the Ḥadīth evaluation and criticism system. Using a descriptive-analytical method, the present study first analyzes their mai...

To determine a detailed picture of tuberculosis (TB) epidemiology in Hamburg, Germany, 423 Mycobacterium tuberculosis complex isolates from 77.0% of all patients with culture-confirmed TB diagnosed from 1997 to 1999 in Hamburg were analyzed by IS6110 DNA fingerprinting. IS6110 restriction fragment length polymorphism (RFLP) clusters were assumed to have arisen from recent transmission. Results ...

Transmission between family members accounts for most Ebola virus transmission, but little is known about determinants of intrahousehold spread. From detailed exposure histories, intrahousehold transmission chains were created for 94 households of Ebola survivors in Sierra Leone: 109 (co-)primary cases gave rise to 317 subsequent cases (0-100% of those exposed). Larger households were more like...

Choosing the optimal compression algorithms for high definition and super high definition video signals including 2K and 4K resolutions and 3D stereoscopic is a complex task because of the technological needs and capabilities of different parts of the production, transmission and archiving chains. Specifics of recording, postproduction, contribution, distribution, transmission, archive and pict...

Even if massive multiple-input multiple-output (MIMO) can theoretically bring huge benefits, it incurs substantial hardware complexity and expensive costs. To address these issues while maintaining the system performance simultaneously, we develop an asymmetrical transceiver architecture for MIMO systems in this paper by releasing shackles on radio frequency (RF) chains. Specifically, first whe...

BACKGROUND Live-animal markets are a culturally important feature of meat distribution chains in many populations, yet they provide an opportunity for the maintenance and transmission of potentially emergent zoonotic pathogens. The ongoing human outbreak of avian H7N9 in China highlights the need for increased surveillance and control in these live-bird markets (LBMs). DISCUSSION Closure of r...
