Global minimum-variance PID control

, 2011
In this paper we address the problem of finding the parameters of a PID controller in order to achieve the minimum variance performance. In particular, a global optimal solution is found by exploiting the analytic expression for the output variance as an

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

Molecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

Long term hedging of the Australian All Ordinaries Index using a bivariate error correction FIGARCH model [PDF]

This article compares the performance of bivariate error correction GARCH and FIGARCH models when estimating long term dynamic minimum variance hedge ratios (MVHRs) on the Australian All Ordinaries Index.

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

Molecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

Minimum-Variance Stock Picking - A Shift in Preferences for Minimum-Variance Portfolio Constituents

, 2014
Minimum-variance (equity) portfolio selection is increasingly popular among investors. We study a broad set of 63 dierent, commonly used approaches to build long-only minimum-variance portfolios among US as well as European stocks.

A Critique of Minimum Variance Hedging

, 2005
This paper provides a critique of minimum variance hedging using futures. The paper develops the conventional minimum variance hedge ratio (MVHR) and discusses its estimation. A review of the wide variety of alternative methods used to construct MVHRs is

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

Molecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

MINIMUM VARIANCE HEDGING AND THE ENCOMPASSING PRINCIPLE: ASSESSING THE EFFECTIVENESS OF FUTURES HEDGES

An empirical methodology is developed for statistically testing the hedging effectiveness among competing futures contracts. The presented methodology is based on the encompassing principle, widely used in the forecasting literature, and applied here to ...
