We address the problem of deciding whether a given network is stable in the Adversarial Queueing Model when considering farthest-from-source (FFS) as the queueing policy to schedule the packets through its links. We show a characterisation of the networks which are stable under FFS in terms of a family of forbidden subgraphs. We show that the set of networks stable under FFS coincide with the s...

This research investigated the effectiveness of IPM/FFS project from economic, technical, social-communicative, environmental and psychological aspects in a descriptive-correlational design based on the survey method. The research population consisted of 70 greenhouse producers that had implemented IPM/FFS project in Tehran and Alborz provinces, Iran. Using Krejcie and Morgan (1970)'s sample si...

Integrating new institutional economics and resource dependence theory, this study investigates whether in transition economies, characterized by shifting from centrally commanded to more market-oriented there are performance differences among family firms (FFs), nonfamily (non-FFs), former state-owned enterprises (former SOEs), political connections affect these differences. Our findings sugge...

Research concerning forefoot strike pattern (FFS) versus rearfoot strike pattern (RFS) running has focused on the ground reaction force even though internal joint contact forces are a more direct measure of the loads responsible for injury. The main purpose of this study was to determine the internal loading of the joints for each strike pattern. A secondary purpose was to determine if converte...

This paper examines published data to develop a model for detecting factors associated with false financia l statements (FFS). Most false financial statements in Greece can be identified on the basis of the quantity and content of the qualification s in the reports filed by the auditors on the accounts. A sample of a total of 76 firms includes 38 with FFS and 38 non-FFS. Ten financial variables...

Little is known about variation in patterns of recovery among patients discharged alive from hospitalizations for pneumonia.The aim of the is observational cohort study was to characterize the variation in patterns of hospital readmission and survival in the year after discharge for pneumonia in 3 different health systems.The 3 cohorts consisted of (1) the Health and Retirement Study participan...

INTRODUCTION Changes in physician reimbursement policies may hinder the collection of billing claims in administrative data; this can result in biased estimates of disease prevalence and incidence. However, the magnitude of data loss is largely unknown. The purpose of this study was to estimate completeness of capture of disease cases for Manitoba physicians paid by fee-for-service (FFS) and no...

We introduce Flip Feng Shui (FFS), a new exploitation vector which allows an attacker to induce bit flips over arbitrary physical memory in a fully controlled way. FFS relies on hardware bugs to induce bit flips over memory and on the ability to surgically control the physical memory layout to corrupt attacker-targeted data anywhere in the software stack. We show FFS is possible today with very...

INTRODUCTION Studies of obesity require the estimation of fat mass (FM) and fat-free mass (FFM); therefore it is important to validate methods that evaluate these measurements. OBJECTIVE We sought to compare two different bioelectrical impedance analysis systems (BIAs) to estimate FM and FFM using dual-energy X-ray absorptiometry (DXA) as reference. METHODS We used a cross-sectional design....

The purpose of this study was to determine the flexural strength and flexural fatigue strength of a machinable composite (GN-I) and three hybrid composites (Artglass, Estenia, and Gradia). Specimens (2 x 2 x 25 mm) were polymerized in a laboratory photo-curing unit and then immersed in water at 37 degrees C for 24 h, 6 months, and 1 year. After each immersion period, flexural strengths (4-PFS) ...
