Subcellular lipid droplets (LDs) in diverse plant cells and species are coated with stabilizing oleosins of at least five phylogenic lineages and perform different functions. We examined two types of inadequately studied LDs for coated oleosins and their characteristics. The epidermis but not mesophyll of leaves of vanilla (Vanilla planifolia) and most other Asparagales species contained solita...

The 1990s saw the widespread adoption of enterprise resource planning (ERP) systems in many countries. Implementation of enterprise-wide systems (ES) continues apace as organizations adopt CRM and SCM packaged software, or replace their aging ERP systems with third-generation ERP packages. These implementations are often motivated by promises of integrated information and processes across the e...

For a large class of vanilla contingent claims, we establish an explicit Föllmer-Schweizer decomposition when the underlying is a process with independent increments (PII) and an exponential of a PII process. This allows to provide an efficient algorithm for solving the mean variance hedging problem. Applications to models derived from the electricity market are performed.

A new binomial approximation to the Black–Scholes model is introduced. It is shown that for digital options and vanilla European call and put options that a complete asymptotic expansion of the error in powers of n−1 exists. This is the first binomial tree for which such an asymptotic expansion has been shown to exist.

as a way to hedge barrier options when the underlying is a futures price with no drift. Derman, Ergener & Hani (1994) relaxed this drift restriction by introducing an algorithm for hedging barrier options in a bi-nomial model, using options with a single strike but multiple expiries. By contrast, this article provides explicit formulas for static hedges in the standard Black-Scholes (1973) mode...

Coronavirus has <span>become one of the most deadly pandemics in 2021. Starting 2019, this virus is now a significant medical issue all over world. It spreading extensively because its modes transmission. The spreads directly, indirectly, or through close contact with infected people. proclaimed that people should wear mask public areas as counteraction measure, it helps suppressing A por...

We describe a natural alternative for training sequence labeling models, based on MIRA (Margin Infused Relaxed Algorithm). In addition, we describe a novel method for performing Viterbi-like decoding. We test MIRA and contrast it with other training algorithms and contrast our decoding algorithm with the vanilla Viterbi algorithm.

In order to demonstrate that rats solve dead reckoning (path integration) tasks in which they return to a starting location using self-movement (idiothetic) cues, it is necessary to remove external (allothetic) cues. Odor cues, especially those generated by a rat on a single passage, are difficult to control and they can potentially serve as a cue to guide a homeward trip. Because it is present...

The analogue of Black–Scholes formula for vanilla call option price in conditions of (B, S)-securities market with delayed response is derived. A special case of continuous-time version of GARCH is considered. The results are compared with the results of Black and Scholes. © 2006 IMACS. Published by Elsevier B.V. All rights reserved.
