Mechanisms of parasite‐mediated disruption of brain vessels

FEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Optimal Filter Length and Zero Padding Length Design for Universal Filtered Multi-Carrier (UFMC) System

IEEE Access, 2019
Universal filtered multi-carrier (UFMC) systems offer flexibility of filtering arbitrary number of subcarriers to suppress out of band emission while keeping the orthogonality between subcarriers and robustness to transceiver imperfections.

CONDITIONAL VAR USING GARCH-EVT APPROACH WITH OPTIMAL TAIL SELECTION

Proceedings of the 10th Economics & Finance Conference, Rome, 2018
Accurate risk prediction plays a key role in effective risk management process. A conditional GARCH-EVT approach combines Extreme Value Theory and GARCH methodology and it allows us to estimate Value at Risk with high accuracy. The approach requires to pre-specify a threshold indicating distribution tails. In this paper we use an optimal tail selection

Portfolio optimization for heavy-tailed assets: Extreme Risk Index vs. Markowitz

, 2015
Using daily returns of the S&P 500 stocks from 2001 to 2011, we perform a backtesting study of the portfolio optimization strategy based on the extreme risk index (ERI).

Fish swimming in schools save energy regardless of their spatial position [PDF]

, 2014
For animals, being a member of a group provides various advantages, such as reduced vulnerability to predators, increased foraging opportunities and reduced energetic costs of locomotion. In moving groups such as fish schools, there are benefits of group

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Asymptotic Properties of Bayes Risk of a General Class of Shrinkage Priors in Multiple Hypothesis Testing Under Sparsity [PDF]

, 2015
Consider the problem of simultaneous testing for the means of independent normal observations. In this paper, we study some asymptotic optimality properties of certain multiple testing rules induced by a general class of one-group shrinkage priors in a ...

Characterizing the salivary RNA landscape to identify potential diagnostic, prognostic, and follow‐up biomarkers for breast cancer

Molecular Oncology, EarlyView.
This study explores salivary RNA for breast cancer (BC) diagnosis, prognosis, and follow‐up. High‐throughput RNA sequencing identified distinct salivary RNA signatures, including novel transcripts, that differentiate BC from healthy controls, characterize histological and molecular subtypes, and indicate lymph node involvement.

Effect of adsorption of surfactant mixtures on wettability of sintering dust [PDF]

Journal of Mining and Metallurgy. Section B: Metallurgy
In order to improve the wettability of sintering dust, we investigated the action mechanism of Triton X-100 (TX-100), which synergizes with Dodecyl Trimethyl Ammonium Bromide (DTAB). The settling times of nine different types of surfactants were measured,

Optimális éves viselkedési modellek: út a fiziológiától a populációkig? = Optimal annual routines: a path from physiology to populations? [PDF]

, 2009
A pályázat fő célja annak kiderítése volt, hogy a különböző állapotváltozók hogyan befolyásolják az optimális viselkedést, speciálisan a hogyan befolyásolják a fő életmenet események időzítését az éves cikluson belül. E cél elérése érdekében több modellt
