Panel Seasonal Unit Root Test With An Application for Unemployment Data [PDF]

open access: yes
In this paper the seasonal unit root test of Hylleberg et al. (1990) is generalized to cover a heterogenous panel. The procedure follows the work of Im, Pesaran and Shin (2002). Test statistics are proposed and critical values are obtained by simulations.

Enhanced discovery of bacterial laccase‐like multicopper oxidase through computer simulation and metagenomic analysis of industrial wastewater

open access: yesFEBS Open Bio, EarlyView.
We obtained potential bacterial laccase‐like multicopper oxidase (LMCO) sequences through metagenomic sequencing. All sequences exhibited significant differences from known LMCOs in databases. To select the most promising candidates, we performed structure prediction and molecular docking using alphafold2, metal3d and rosetta.

A Nonlinear Unit Root Test in the Presence of an Unknown Break [PDF]

open access: yes
The Perron test is the most commonly applied procedure to test for a unit root in the presence of a structural break of unknown timing in the trend function.

KCS1 and VIP1, the genes encoding yeast phosphoinositol pyrophosphate synthases, are required for Ca2+‐mediated response to dimethylsulfoxide (DMSO)

open access: yesFEBS Open Bio, EarlyView.
Ca2+‐mediated response to DMSO was investigated in Saccharomyces cerevisiae cells expressing Ca2+‐dependent aequorin. Cell exposure to DMSO induced a cytosolic Ca2+ wave dependent on the integrity of the Cch1/Mid1 channel. Deletion of KCS1 or VIP1 genes encoding the phosphoinositol pyrophosphate (PP‐IP) synthases suppressed the DMSO‐induced Ca2 ...

Analysis of Income Convergence in G-20 Countries with Structural Break Unit Root Test

open access: yesInternational Journal of Economics and Financial Issues, 2018
In the globalizing world, the convergence of countries can’t be avoided. Any phenomenon in a country can reach other countries within a short period of time. Therefore, the article was made by using G - 20 countries that came together for a purpose.

Development of 4T1 breast cancer mouse model system for preclinical carbonic anhydrase IX studies

open access: yesFEBS Open Bio, EarlyView.
Carbonic anhydrase IX (CAIX) is a well‐recognised therapeutic target and prognostic biomarker in cancer. We developed and characterised a robust murine breast cancer model system that is suitable for CAIX studies in vitro and in vivo—it comprises both CAIX‐positive and CAIX‐negative controls and provides a solid platform for the comprehensive ...
