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.

FEBS Letters, EarlyView.Bone metastasis in prostate cancer (PCa) patients is a clinical hurdle due to the poor understanding of the supportive bone microenvironment. Here, we identify stearoyl‐CoA desaturase (SCD) as a tumor‐promoting enzyme and potential therapeutic target in bone metastatic PCa.

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

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

Algebraic Closed Geodesics on a Triaxial Ellipsoid [PDF]
, 2005 We propose a simple method of explicit description of families of closed geodesics on a triaxial ellipsoid $Q$ that are cut out by algebraic surfaces in ${\mathbb R}^3$.

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.
