Admission control for a capacitated supply system with real-time replenishment information
(Elsevier, 2023)Control towers can provide real-time information on logistic processes to support decision making. The question however, is how to make use of it and how much it may save. We consider this issue for a company supplying ... -
Evaluating the phyto-complexity and poly-pharmacology of spices: The case of Aframomum melegueta K. Schum (Zingiberaceae)
(Elsevier, 2022)The seeds of Aframomum melegueta K. Schum (grains of paradise, Zingiberaceae) are used as a common spice in African countries and a fine condiment in the European cuisine. In this study, we evaluated the phytochemical ... -
Scarcity improves economic valuations when cognitively salient
(Elsevier, 2023)In an influential article, Shah et al. (2015) hypothesized that resource scarcity weakens the effect of irrelevant contextual factors on economic valuations. The hypothesis that scarcity frames value qualifies the applicability ... -
Modeling repair demand in existence of a nonstationary installed base
(Elsevier, 2023)Life cycles of products consist of 3 phases, namely growth, maturity, and decline phases. Modeling repair demand is particularly difficult in the growth and decline stages due to nonstationarity. In this study, we suggest ... -
Gathering scientific evidence for a new bioactive natural ingredient: The combination between chemical profiles and biological activities of Flueggea virosa extracts
(Elsevier, 2022)Flueggea virosa (Roxb. ex Willd.) Royle is a plant with several traditional uses in tropical countries. To study the potential usefulness, extracts from stem barks and leaves of F. virosa were obtained with different ... -
The in-vivo assessment of Turkish propolis and its nano form on testicular damage induced by cisplatin
(Elsevier, 2021)Objective: Chemotherapeutic drugs, such as cisplatin (CP), which are associated with oxidative stress and apoptosis, may adversely affect the reproductive system. This study tests whether administration of propolis and ... -
State capitalism and hydrocarbon security in China and Russia
(Elsevier, 2021)This study seeks to investigate how and why state capitalism developed in China and Russia in the oil and gas sectors and explain why two countries that have contrasting energy-security challenges use state capitalism to ... -
Four-searchable biconnected outerplanar graphs
(Elsevier, 2022)This paper deals with constructing obstruction sets for two subclasses of 4-searchable graphs. We first characterize the 4-searchable biconnected outerplanar graphs by listing all graphs that cannot be their minors; we ... -
Potential allosteric sites captured in glycolytic enzymes via residue-based network models: Phosphofructokinase, glyceraldehyde-3-phosphate dehydrogenase and pyruvate kinase
(Elsevier, 2022)Likelihood of new allosteric sites for glycolytic enzymes, phosphofructokinase (PFK), glyceraldehyde-3phosphate dehydrogenase (GADPH) and pyruvate kinase (PK) was evaluated for bacterial, parasitic and human species. ... -
Maintenance optimization for a single wind turbine component under time-varying costs
(Elsevier, 2022)In this paper, we introduce a new, single-component model for maintenance optimization under timevarying costs, specifically oriented at offshore wind turbine maintenance. We extend the standard age replacement policy ... -
Susceptible-infectious-susceptible (SIS) model with virus mutation in a variable population size
(Elsevier, 2022)The complex dynamics of a contagious disease in which populations experience horizontal and vertical transmissions, size variation, and virus mutations are of considerable practical and theoretical interest. We model such ... -
The role of atomistic processes in growth of Cu-Ni metallic/bimetallic nanoparticles
(Elsevier, 2023)Controlling the morphology of non-noble bimetallic nanocrystals can provide an excellent opportunity to improve performance and activity in catalytic reactions. Although several studies have focused on the overall macroscopic ... -
Integration of in vitro and in silico approaches to assess three Astragalus species from Turkey flora: A novel spotlight from lab bench to functional applications
(Elsevier, 2022)Members of the genus Astragalus have a great interest as a source of natural bioactive compounds on a scientific platform. To provide multidirectional insights into three Astragalus species (A. setulosus, A. anthylloides, ... -
Information shocks and the cross section of expected returns
(Elsevier, 2023)This paper examines the risk premium associated with information shocks in equity markets. For all stocks traded on Borsa Istanbul between March 2005 and December 2020, we calculate information shocks as unanticipated ... -
Dual sourcing models with stock-out dependent substitution
(Elsevier, 2023)Companies use different criteria such as lead time, cost and quality to evaluate suppliers; often using multiple suppliers with the aim of reducing stockout risk. But in many industries there may be significant differences ... -
A multi-objective optimization evaluation framework for integration of distributed energy resources
(Elsevier, 2021)Renewable distributed generation and energy storage systems (ESSs) have been a gamechanger for a reliable and sustainable energy supply. However, this new type of generation should be optimally planned and operated to ... -
Optimum utilization of on-demand manufacturing and laser polishing in existence of supply disruption risk
(Elsevier, 2022)3D printing has moved from being a rapid prototyping tool to an additive manufacturing method within the last decade. Additive manufacturing can satisfy the need in dire situations where spare parts distribution is an issue ... -
The Effect of Pandemics on Domestic Credit: A Cross-country Analysis
(Economics Bulletin, 2021)Using a panel of 140 countries covering the period 1996-2018, this paper examines how previous pandemics (such as SARS, MERS, Ebola, Swine flu, etc.) have influenced the lending behavior of banks. We take advantage of a ... -
