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...

While classification techniques can be applied for automatic unknown word recognition in a language without word boundary, it faces with the problem of unbalanced datasets where the number of positive unknown word candidates is dominantly smaller than that of negative candidates. To solve this problem, this paper presents a corpus-based approach that introduces a so-called group-based ranking e...

As cyberattacks become more intelligent, the difficulty increases for traditional intrusion detection systems to detect advanced attacks that deviate from previously stored patterns. To solve this problem, a deep learning-based system model has emerged analyzes intelligent attack patterns through data learning. However, learning models have disadvantage of having re-learn each time new cyberatt...

BACKGROUND Hyperkalemia is a potentially life-threatening condition that patients with heart failure or chronic kidney disease, especially those taking renin-angiotensin-aldosterone system inhibitors, are at high risk of developing. Sodium polystyrene sulfonate (SPS), a current treatment, binds potassium within the gastrointestinal tract to reduce potassium absorption. However, poor palatabilit...

Indonesia merupakan salah satu negara penghasil vanili (Vanilla planifolia A.) terbesar di dunia. Perbanyakan tanaman dengan cara vegetatif yang menggunakan bahan setek terdiri dari 1-3 ruas, setiap buku mempunyai potensi mengeluarkan akar dan tunas sehingga tersebut memunginkan dapat diperbanyak dengen setek, namun kemampuan untuk tumbuh sangat rendah, maka diperlukan perlakuan khusus pemberia...

We analyse a model for pricing derivative securities in the presence of both transaction costs as well as the risk from a volatile portfolio. The model is based on the Black-Scholes parabolic PDE in which transaction costs are described following the Hoggard, Whalley, and Wilmott approach. The risk from a volatile portfolio is described by the variance of the synthesized portfolio. Transaction ...

A new family of binomial trees as approximations to the Black–Scholes model is introduced. For this class of trees, the existence of complete asymptotic expansions for the prices of vanilla European options is demonstrated and the first three terms are explicitly computed. As special cases, a tree with third order convergence is constructed and the conjecture of Leisen and Reimer that their tre...
