Modelling the Impact of Travel Time Uncertainty to the Cocoa Supply Chain Network

open access: yesJurnal Teknik Sipil, 2018
The uncertainty issue becoming more and more important in term of freight transport, which essentially affect the transport cost. As an essential parameter to construct the product price, the transport cost variations sequentially impact the supply chain

Bullwhip Effect Study in Leaf Organic Supply Chain

open access: yesAgraris: Journal of Agribusiness and Rural Development Research, 2021
The mismatch between the availability of vegetables and consumer demand is one of the causes of inefficient supply chains. This study aims to analyze the bullwhip effect on the organic leaf vegetable supply chain at PT Simply Fresh Organic (SFO).

Quadratic Variation by Markov Chains [PDF]

open access: yesSSRN Electronic Journal, 2009
We introduce a novel estimator of the quadratic variation that is based on the the- ory of Markov chains. The estimator is motivated by some general results concerning …ltering contaminated semimartingales. Speci…cally, we show that …ltering can in prin- ciple remove the eects of market microstructure noise in a general framework where little is ...

Copper Ions Induce DNA Sequence Variation in Zygotic Embryo Culture-Derived Barley Regenerants

open access: yesFrontiers in Plant Science, 2021
In vitro tissue culture could be exploited to study cellular mechanisms that induce sequence variation. Altering the metal ion composition of tissue culture medium affects biochemical pathways involved in tissue culture-induced variation. Copper ions are

High Prevalence of CTXM-15 Type Extended-Spectrum Beta-Lactamase Among Clinical Isolates of Klebsiella Pneumoniae [PDF]

open access: yesJournal of Kerman University of Medical Sciences, 2019
Background: Production of β–lactamases by enterobacteriacea, especially Klebsiella pneumoniae, is one of the emerging health problems in the world. The purpose of this study was to assess the frequency of blaCTX-M15 gene in K.

Epigenetic Control of Salmonella enterica O-Antigen Chain Length: A Tradeoff between Virulence and Bacteriophage Resistance. [PDF]

open access: yesPLoS Genetics, 2015
The Salmonella enterica opvAB operon is a horizontally-acquired locus that undergoes phase variation under Dam methylation control. The OpvA and OpvB proteins form intertwining ribbons in the inner membrane.

Chain rules and p-variation [PDF]

open access: yesStudia Mathematica, 2002
The main result of this paper is a Young-Stieltjes integral representation of the composition \(\phi\circ f\) of a smooth function \(\phi\) that has a derivative satisfying a Lipschitz condition of order \(\alpha\in(0,1]\) and a ``rough'' function \(f\) with bounded \(p\)-variation for some ...

TOWARD THE THEORY OF THE SUPPLY CHAIN [PDF]

open access: yes, 2015
As our discipline has matured, we have begun to develop theories of supply chain management. However, we submit that a major omission of theory development in the supply chain management discipline is that we have failed to develop a theory of what we ...

Fructan synthesis, accumulation and polymer traits. II. Fructan pools in populations of perennial ryegrass (Lolium perenne L.) with variation for water-soluble carbohydrate and candidate genes were not correlated with biosynthetic activity and demonstrated constraints to polymer chain extension

open access: yesFrontiers in Plant Science, 2015
Differences have been shown between ryegrass and fescue within the Festulolium subline introgression family for fructan synthesis, metabolism and polymer-size traits.
