However, because the main purpose of eCDAs is to provide clinicians with diagnostic guidance, the principles of the evidence trajectory could be similar to those of laboratory diagnostic tests (Fig. 3). Download: Download high-res image (520KB) Download: Download full-size image Fig. 3. ...
Main Inheritance, variation and selection are foundational principles of Darwinian organismal evolution that have been used to explain how cancers emerge, progress and adapt1,2,3,4. The concept of genetic identity by descent is central to the application of evolutionary theory to cancer, suggesting ...
dominated by China. Because of this,the Biden administration is working to build resilient, enduring supply chains with partners and allies in important areas, including semiconductors, phar- maceuticals and biotechnology, criti- cal minerals, and batteries, so that the United States is not ...
However, because different developmental stages co-occur in close contact inside the nest, different types of social interactions might be confounded or difficult to discern. Therefore, we cannot fully describe the principles of interactions between individuals and how each developmental stage contributes ...
"Quali-Set-Practice" aims at analyzing the functional principles of health promotion and refers to the dilemmas described by Koelen et al. [36] in addressing the following questions: (1) How does a health promotion programme work in the setting town district? How are activities for health...
Theory and principles of SPE Solid-phase extraction (SPE) is an effective way to prepare samples in chemistry. A sample collection and analysis gap can be closed using SPE as one of the methods. It is rarely used with no further preparation steps, such as dilution or pH adjustment [1,2,...

2. Principles 2.1. Electrochemical drilling In ECD, a hollow metal tube covered with an insulation layer is used as the cathode tool, whereas the workpiece is acted as an anode electrode. During drilling, the electrolyte is supplied into the tube electrode and then flows at high speed through...
The performance of the device is mainly determined by the pump. Several working principles are used for microp- ump as described in recent reviews [14,15]. Osmotic pumps [16–18] are compact, easy to fabricate, and do not require external energy source, but provide a small and unregulated...
The properties of π-conjugated oligomers and polymers are commonly controlled by side group engineering, main chain engineering, or conformational engineering. The last approach is typically limited to controlling the dihedral angle around the interring single bonds to prevent loss of π-conjugation. ...
