Is Per Capita Real GDP Stationary in the OECD Countries? Evidence from a Panel Unit Root Test [PDF]

open access: yes
This paper examines the stationarity of real GDP per capita for 27 OECD countries during the period 1950 to 2004. Using ADF unit root test on single time series, it is found that real GDP per capita series of most OECD countries have unit root.

Revealing protein structures: crystallization of protein‐ligand complexes – co‐crystallization and crystal soaking

open access: yesFEBS Open Bio, Volume 15, Issue 4, Page 542-550, April 2025.
Co‐crystallization crystallizes a protein with its ligand, resulting in protein–ligand complex crystals. In contrast, soaking introduces a ligand into preformed protein crystals, allowing it to bind. Both methods produce crystals for X‐ray diffraction, which generates diffraction patterns that are analyzed to determine the three‐dimensional structure ...

Testing for a unit root in the presence of a possible break in trend [PDF]

open access: yes
In this paper we consider the issue of testing a time series for a unit root in the possible presence of a break in a linear deterministic trend at some unknown point in the series.

Testing for Unit Roots with Cointegrated Data [PDF]

open access: yes, 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.

Protein crystallization and structure determination at room temperature in the CrystalChip

open access: yesFEBS Open Bio, Volume 15, Issue 4, Page 532-541, April 2025.
This protocol describes the implementation of a simple and user‐friendly microfluidic device called CrystalChip that allows the production of crystals by the counter‐diffusion method and their in situ analysis by serial crystallography. As an illustration, it is applied to determine the 3D structure of three proteins from data collected at room ...

Real‐world genomic landscape of colon and rectal cancer

open access: yesFEBS Open Bio, Volume 15, Issue 4, Page 674-685, April 2025.
We confirmed enrichment of RTK alterations in patients with RAS/BRAF‐wt tumors and of PI3K pathway alterations in RAS/BRAF‐altered tumors with 51 982 real‐world tissue comprehensive genomic profiling (CGP) samples in CRC. In a subset of 140 patients with both tissue and liquid results, the sensitivity of liquid for results found by tissue was 100% when
