Seasonal Unit Root Tests under Structural Breaks [PDF]
In this paper, several seasonal unit root tests are analysed in the context of structural breaks at known time and a new break corrected test is suggested.

MITF maintains genome stability in nonmelanocyte lineages
Molecular Oncology, EarlyView.MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

Molecular Oncology, EarlyView.Single‐cell multi‐omics reveals epigenetic heterogeneity across therapy‐adaptive tumor states, including quiescent/dormant, drug‐tolerant persister, and EMT‐like phenotypes. By linking regulatory features with state‐associated biomarkers, these approaches inform biomarker‐guided therapeutic strategies for evolving tumors.

Examining the Islamic stock market efficiency: Evidence from nonlinear ESTAR unit root tests
Indonesian Capital Market Review, 2015 This paper empirically examines the efficient market hypothesis (EMH) in the Islamic stock market namely Jakarta Islamic Index by emphasizing on the random walk behavior and nonlinearity. In the first step, we employ Brock et al.

Testing for Unit Roots with Cointegrated Data [PDF]
, 2015 This paper demonstrates that unit root tests can suffer from inflated Type I error rates when data are cointegrated. Results from Monte Carlo simulations show that three commonly used unit root tests - the ADF, Phillips-Perron, and DF-GLS tests - frequently overreject the true null of a unit root for at least one of the cointegrated variables.

Molecular Oncology, EarlyView.Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.

Fisher hypothesis: East Asian evidence from panel unit root tests [PDF]
This study provides evidence supportive of Fisher hypothesis in East Asian economies using panel unit root tests, which allow for cross-country variations in the estimation.
