Fractional Integration and Business Cycles Features [PDF]
We show in this article that fractionally integrated univariate models for GDP may lead to a better replication of business cycle characteristics. We firstly show that the business cycle features are clearly affected by the degree of integration as well ...

Molecular Oncology, EarlyView.LUNAR is a liver‐specific long noncoding RNA (lncRNA) that is highly expressed in normal liver but becomes epigenetically silenced in hepatocellular carcinoma through promoter hypermethylation. Loss of LUNAR is associated with NOTCH activation, epithelial–mesenchymal transition, and metastasis, whereas restoring LUNAR restrains metastatic progression ...

Further evidence on the PPP analysis of the Australian dollar: non-linearities, fractional integration and structural changes [PDF]
The aim of this paper is to analyse the empirical fulfilment of the Purchasing Power Parity (PPP) theory for the Australian dollar. In order to do so we have applied recently developed unit root tests that account for asymmetric adjustment towards the ...

A Long-Memory Model for Multiple Cycles with an Application to the US Stock Market
MathematicsThis paper proposes a long-memory model that includes multiple cycles in addition to the long-run component. Specifically, instead of a single pole or singularity in the spectrum, it allows for multiple poles and, thus, different cycles with different ...

Molecular Oncology, EarlyView.Single‐cell DNA methylation (scDNAme) profiling maps epimutational clonal evolution, revealing mechanisms of malignancy and therapeutic resistance across diverse cancer types. By providing a high‐resolution landscape of intratumoral heterogeneity, these technologies empower precise patient stratification, guide the development of enhanced ...

REAL EXCHANGE RATES IN LATIN AMERICA: THE PPP HYPOTHESIS AND FRACTIONAL INTEGRATION [PDF]
This paper tests for PPP in a group of seventeen Latin American (LA) countries by applying fractional integration techniques to real exchange rate series. Compared to earlier studies on these economies, this approach has the advantage of allowing for non-

On Weighted Fractional Integral Inequalities
Journal of Functional Analysis, 2001 The author studies weighted positivity of a fractional power \((-\Delta)^\lambda\) of the Laplace operator, the weight function being the fundamental solution of this fractional power. Let \[ f(n,\lambda)=\psi\left(\frac{n}{2}\right)-\psi\left(\frac{n}{2}-\lambda\right)- \psi(\lambda) +\psi(1).

Molecular Oncology, EarlyView.The cell‐autonomous roles of interferon type 1 vary based on duration and intensity. While acute, robust signaling results in cancer cell cytotoxic effects, sustained, low‐level signaling is associated with tumor‐promoting effects. This review summarizes current research of IFN‐1 in cancer and within the clinical setting, with an emphasis on female ...

Cointegration in Fractional Systems with Unknown Integration Orders [PDF]
Cointegration of nonstationary time series is considered in a fractional context. Both the observable series and the cointegrating error can be fractional processes. The familiar situation in which the respective integration orders are 1 and 0 is nested,
