Yankuang ceshi, 2013 The process capability index (CPK) is the value that measures the degree of process capability to meet the quality standard of products. In the process control, if the CPK is bigger, the product quality is better.

FEBS Letters, EarlyView.Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

FEBS Letters, EarlyView.Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Role of ‘corporate persistence’ and ‘environmental support’ in building breakthrough capability: Empirical investigation of Samsung’s initiatives in memory and microwave oven business [PDF]
It is now an incontrovertible fact that capabilities are the source of competitive advantage. However, the process through which firms build capabilities over a period of time is only partially understood.

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

, 2016 碩士本文除針對小樣本且殘差項具自我相關的線性輪廓資料提出一個新的T_new^2管制圖，增加對製程偏移的偵測能力外，也考量當前文獻對輪廓資料的製程能力尚缺乏完整討論，實務上若忽略反應變數與解釋變數之間的函數關係，直接使用多變量的製程能力指標衡量輪廓資料的製程能力，可能導致不適當的估計結果。因此本論文針對殘差項間存在ㄧ階自我相關的線性輪廓資料提出兩個新的製程能力指標。模擬研究結果發現，當輪廓內截距項與斜率項發生變動時，在小樣本及殘差項的相關係數越高時，T_new^2 管制圖對製程的偏移有較好的偵測能力 ...

FEBS Letters, EarlyView.Protein aggregates threaten proteostasis and cell health. In human cells, Hsp70–J‐domain protein‐based disaggregases remove aggregates, but how they assemble remains unclear. Our biochemical findings show that DNAJA2‐ and DNAJB1‐containing disaggregase scaffolds enhance luciferase aggregate targeting, and that Hsp70 recruitment by both J‐domain ...
