American Journal of Agricultural Economics, EarlyView.Abstract Germany's Renewable Energy Sources Act (REA), enacted in 2000 and subsequently amended, subsidized national renewable energy production with fixed feed‐in tariffs for renewable energy sources (RE) from wind, solar, and biogas. Empirical studies suggest that the policy was creating windfall effects for landowners and attribute farmland use ...

Journal of Algorithms & Computational Technology, 2009 This paper addresses the static scheduling of a directed acyclic task graph (DAG) on a heterogeneous, bounded set of distributed processors to minimize the makespan. We first derive the lower and upper bounds on the makespan of assigning a given directed

One Edge at a Time: A Novel Approach Towards Efficient Transitive Reduction Computation on DAGs
IEEE Access, 2020 Given a directed acyclic graph (DAG) G, G's transitive reduction (TR) Gtr is the unique DAG satisfying that Gtr has the minimum number of edges and has the same transitive closure (TC) as G.

Ramsey theory and thermodynamics
Heliyon, 2023 Re-shaping of thermodynamics with the graph theory and Ramsey theory is suggested. Maps built of thermodynamic states are addressed. Thermodynamic states may be attainable and non-attainable by the thermodynamic process in the system of constant mass. We

The Risk of Cardiovascular Diseases for Shift Workers in the Prospective Heinz Nixdorf Recall Study
American Journal of Industrial Medicine, EarlyView.ABSTRACT Background Shift work can disrupt circadian rhythms and is postulated to play a role in cardiovascular diseases (CVD). In the German prospective population‐based Heinz Nixdorf Recall Study, we analyzed longitudinal associations between shift work and night‐shift work with CVD.

Arthritis &Rheumatology, EarlyView.Objective To examine the association between radiographic structural damage and physical function (PF) in psoriatic arthritis (PsA). Methods Data were analyzed from a large longitudinal PsA cohort. PF was measured using the Health Assessment Questionnaire (HAQ, 0–3) and Short Form‐36 PF subscale (SF‐36, 0–100); radiographic joint damage was measured ...

DAG Based Multipath Routing Algorithm for Load Balancing in Machine-to-Machine Networks
International Journal of Distributed Sensor Networks, 2013 In M2M networks, most nodes are powered by battery; hence the overused nodes may easily be out of power, which causes the reduction of network lifetime.

Arthritis &Rheumatology, EarlyView.Objective The purpose of this study was to estimate the prevalence of difficult‐to‐manage (D2M) and treatment‐refractory (TR) axial spondyloarthritis (axSpA) and to identify factors associated with D2M and TR disease in a longitudinal cohort. Methods We performed a cross‐sectional analysis on data from the Schroeder Arthritis Institute Spondylitis ...
