Response of changes in lake area to drought and land use change.

The lake area is a crucial parameter that characterizes the state of a lake. Under the dual pressures of climate change and human activity, the magnitude and frequency of changes in lake areas become more pronounced. This process poses a serious threat to the local ecological environment.

Supertough poly(lactic acid)/bio-polyurethane blends fabricated by dynamic self-vulcanization of dual difunctional monomers.

In this work, a facile and efficient strategy known as 'dynamic self-vulcanization of dual difunctional monomers' was reported to toughen poly(lactic acid) (PLA) with in-situ formed crosslinked bio-polyurethane (PCPUE) phase from plant oil-derived hydrogenated dimer diol (Pripol) and hexamethylene diisocyanate (HDI). By simply adjusting equivalent ratios (n/n) of complementary functional groups between these two difunctional toughening monomers from 1.0 to 2.

FFT-based equal-integral-bandwidth feature extraction of vibration signal of OLTC.

This study aimed to propose an equal-integral-bandwidth feature extraction method based on fast Fourier transform (FFT) to solve the problem of cumbersome processing and a large amount of calculation in the common feature extraction algorithm for vibration signals of on-load tap changer (OLTC). First, the vibration signals of OLTC were preprocessed in segments, which highlighted the status features and avoided the shortcomings of the FFT spectrum that lacked time axis information. Second, the vibration signal segments were analyzed with FFT, and the generated signal spectrum was divided into several segments according to equal integral.

SOX11 inhibits tumor proliferation and promotes cell adhesion mediated-drug resistance via a CD43 dependent manner in mantle cell lymphoma.

SOX11 is a critical biomarker for mantle cell lymphoma (MCL) diagnosis; however, its role remains unclear in MCL. Here, clinical-pathological analysis showed Ki67 index was negatively relevant to SOX11 expression only in CD43 positive cases. Coexpression of SOX11/CD43 indicated longer overall survival.

Foam Cell-Derived CXCL14 Muti-Functionally Promotes Atherogenesis and Is a Potent Therapeutic Target in Atherosclerosis.

CXC chemokine family has been related to atherogenesis for long. However, the relationship between CXCL14 and atherogenesis is still unclear. This study preliminarily detected CXCL14 expression at foam cells in atherosclerosis specimens by immunohistochemistry.

[Appropriate parameters for high-yielding cultivation of machine-transplanted rice].

A field experiment with japonica rice variety Wuxiangjing 14 in 2002-2005 showed that the appropriate sowing rate was 150-180 g per tray (1624 cm2), seedling-strengthening agent was more conducive than compound fertilizer in improving the quality of machine-transplanted seedlings, the rational dose of compound fertilizer (N-P2O5-K2O) was 150 g x m(-2), seedlings should be machine-transplanted within 21 days after sowing, densely planting a fewer seedlings in each cluster could improve the individual and population quality of machine-transplanted rice, and applying 315 kg x hm(-2) of N and 6:4 of basal-tillering: heading fertilizer could obtain the highest rice yield. The marked increase of glumous flowers per unit area was the main cause of the increase of machine-transplanted rice yield.
