Evolution of Seal Cutting Symbol Elements [PDF]
Proceedings of the 2016 International Conference on Arts, Design and Contemporary Education, 2016 Seal cutting is a traditional art and it is the predecessor of one of the four inventions-printing which closely combined with the calligraphy, so far it has 3000 years of history. Also it is the prototype of Chinese logo design so its cultural status can not be ignored.

Cut finite element methods for coupled bulk–surface problems [PDF]
Numerische Mathematik, 2015 We develop a cut finite element method for a second order elliptic coupled bulk-surface model problem. We prove a priori estimates for the energy and $L^2$ norms of the error. Using stabilization terms we show that the resulting algebraic system of equations has a similar condition number as a standard fitted finite element method.

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

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Synergies in control of the cutting processes
MATEC Web of Conferences, 2018 As the rule metal-cutting machine have controllable movements of the executive tool from the computer. However, the shape-generating movements differ from the executive elements movements. These differences are defined by the influence of the deformation

FEBS Letters, EarlyView.Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.
