Principle and progress of attosecond pulse generation [PDF]
Chinese Science Bulletin, 2021 With the rapid development of laser technology, the vision of attosecond world has been unfolded. Since the first isolated attosecond pulses produced by high-order harmonic generation in 2001, the time-resolved spectroscopy has entered the attosecond domain and greatly strengthened our understanding of ultrafast electron dynamics in atoms, molecules ...

Revascularization of decellularized lung scaffolds: principles and progress [PDF]
American Journal of Physiology-Lung Cellular and Molecular Physiology, 2015 There is a clear unmet clinical need for novel biotechnology-based therapeutic approaches to lung repair and/or replacement, such as tissue engineering of whole bioengineered lungs. Recent studies have demonstrated the feasibility of decellularizing the whole organ by removal of all its cellular components, thus leaving behind the extracellular matrix ...

Genesis and progress of virtual power principle
Acta Mechanica, 2022 AbstractThe virtual power principle (VPP) of continuum mechanics states a celebrated variational equality between external and internal virtual powers for any virtual velocity field conforming with linear kinematic constraints. The topic is here addressed to investigate how the original ideas born in the early XIX century are modelled by modern ...

Tax uniformity as a requirement of justice [PDF]
, 2020 Barbara Fried takes the view that uniform taxation-that is, a single rate applicable to all income levels-cannot be defended on any grounds of justice. She goes further by saying that, of all possible rate structures, it might be "the hardest one"?

Progress of Inertial Microfluidics in Principle and Application
Sensors, 2018 Inertial microfluidics has become a popular topic in microfluidics research for its good performance in particle manipulation and its advantages of simple structure, high throughput, and freedom from an external field. Compared with traditional microfluidic devices, the flow field in inertial microfluidics is between Stokes state and turbulence ...

Progressivity of Taxes, Skeweness of Income Distribution and Violations of the Progressive Principle in Income Tax Systems [PDF]
Statistika: Statistics and Economy Journal, 2014 Kakwani and Lambert state the three axioms, which should be respected by an equitable tax system. They also proposed a measurement system to evaluate the violations of the axioms. One of the axioms, axiom 2, formulates the progression principle in income

Classification of the primary progressive aphasias: principles and review of progress since 2011 [PDF]
Alzheimer's Research & Therapy, 2016 AbstractHighly influential recommendations published in 2011 for the classification of the primary progressive aphasias (PPA) distinguished three subtypes: the semantic variant, the nonfluent/agrammatic variant, and the logopenic variant. We review empirical evidence published after 2011 that bears relevance to the validity of the recommended ...
