The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome
FEBS Letters, EarlyView.This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Semiampleness For Calabi-Yau Surfaces In Positive And Mixed Characteristic
In this note, we prove the semiampleness conjecture for Kawamata log terminal Calabi-Yau (CY) surface pairs over an excellent base ring. As applications, we deduce that generalized abundance and Serrano's conjecture hold for surfaces.

FEBS Letters, EarlyView.An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Characteristic scales in supersonic combustion
, 2013 The characteristic length scales in supersonic combustion and the related influence factors were calculated and analyzed. In addition, using the hydrogen, ethylene and kerosene as fuels, the operating range of scramjet under the practical flight ...

FEBS Letters, EarlyView.The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

The study of the characteristic polynomial of graphs
, 2011 碩士假設A是n階方陣，A的特徵多項式為p(A,x)=det(xI-A)，其中I是n階單位方陣。令G為一含有n個點的簡單圖且A(G)為圖G的鄰接矩陣， 我們稱A(G)的特徵多項式為G的特徵多項式，記為p(G,x)=det(xI-A(G))，其中I是n階單位方陣。 在本論文中我們直接計算出完全圖與星圖的特徵多項式，對於路徑與迴圈我們可得其遞迴關係式；由前面的計算我們得到行列式的化簡與圖之間的關係，推導出圖中含有degree 1的點或含有degree 2的點及含有一個橋的特徵多項式 ...

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.
