Statistical significance and its meaning [PDF]

open access: yesPsihološka Obzorja, 2005
The most frequently method of data analysis in psychology is null hypothesis significance testing (NHST); this work identifies the misunderstandings and consequent biases due to the unwitting use of this hybrid approach, derived by the fusion of the p ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Monitoring lake populations of Eastern Sand Darter (Ammocrypta pellucida): a comparison of two seines

open access: yesJournal of Freshwater Ecology, 2017
For many imperiled fishes in the Laurentian Great Lakes basin, detection protocols and population monitoring programs are lacking. In this study, we used a repeat-sampling approach to compare the effectiveness of two seines (bag and beach) to detect and ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

De-risking transient stability of AC/DC power systems based on ESS integration

open access: yesThe Journal of Engineering, 2019
Owing to the charging/discharging flexibility, electric storage system (ESS) is widely recognised as a promising technique that can be introduced to enhance transient stability of power systems.

Coded power control: Performance analysis [PDF]

open access: yes2013 IEEE International Symposium on Information Theory, 2013
In this paper, we introduce the general concept of coded power control (CPC) in a particular setting of the interference channel. Roughly, the idea of CPC consists in embedding information (about a random state) into the transmit power levels themselves: in this new framework, provided the power levels of a given transmitter can be observed (through a ...

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

A high speed truly random number generator based on thermal noise oscilltor

open access: yesDianzi Jishu Yingyong, 2018
A truly random number generator based on thermal noise was proposed, and the resistance thermal noise was used as the noise source of the low frequency clock. It uses two independent working relative relationship between high and low frequency oscillator

A computational description of simple mediation analysis [PDF]

open access: yesTutorials in Quantitative Methods for Psychology, 2018
Simple mediation analysis is an increasingly popular statistical analysis in psychology and in other social sciences. However, there is very few detailed account of the computations within the model.

Power analysis for random‐effects meta‐analysis [PDF]

open access: yesResearch Synthesis Methods, 2017
One of the reasons for the popularity of meta‐analysis is the notion that these analyses will possess more power to detect effects than individual studies. This is inevitably the case under a fixed‐effect model. However, the inclusion of the between‐study variance in the random‐effects model, and the need to estimate this parameter, can have ...
