Reconsidering Dogmas about the Growth of Bacterial Populations

open access: yesCells, 2023
The growth of bacterial populations has been described as a dynamic process of continuous reproduction and cell death. However, this is far from the reality.

Inhomogeneous Coupling in Two-Channel Asymmetric Simple Exclusion Processes [PDF]

open access: yes, 2007
Asymmetric exclusion processes for particles moving on parallel channels with inhomogeneous coupling are investigated theoretically. Particles interact with hard-core exclusion and move in the same direction on both lattices, while transitions between ...

Quantitative proteomics reveals that dormancy-related proteins mediate the attenuation in mycobacterium strains

open access: yesVirulence, 2021
Although members of the Mycobacterium tuberculosis complex (MTBC) exhibit high similarity, they are characterized by differences with respect to virulence, immune response, and transmissibility.

Capillary Gas Chromatographic Separation Performances of a Tetraphenyl Porphyrin Stationary Phase

open access: yesFrontiers in Chemistry, 2022
Tetraphenyl porphyrin (TPP) has enormous potential for use as gas chromatography stationary phases because it has a distinctive extended π–π conjugated coplanar structure and a range of interesting properties such as a good solubility in dichloromethane,

Limitations on the principle of stationary phase when it is applied to tunneling analysis [PDF]

open access: yes, 2007
Using a recently developed procedure - multiple wave packet decomposition - here we study the phase time formulation for tunneling/reflecting particles colliding with a potential barrier. To partially overcome the analytical difficulties which frequently

On the periodicity of oscillatory reconnection [PDF]

open access: yes, 2012
Context. Oscillatory reconnection is a time-dependent magnetic reconnection mechanism that naturally produces periodic outputs from aperiodic drivers. Aims.

Chromatographic and spectroscopic studies on β-cyclodextrin functionalized ionic liquid as chiral stationary phase: Enantioseparation of NSAIDs

open access: yesAdsorption Science & Technology, 2018
Recently, we reported a new chiral stationary phase prepared using β-cyclodextrin functionalized with aromatic ionic liquid which is aimed to enhance the performance of enantioseparation of flavonoids and β-blockers.

A Phase Front Instability in Periodically Forced Oscillatory Systems

open access: yes, 1998
Multiplicity of phase states within frequency locked bands in periodically forced oscillatory systems may give rise to front structures separating states with different phases. A new front instability is found within bands where $\omega_{forcing}/\omega_{

Research Progress in the Preparation and Applications of Hydrophilic Chromatographic Materials for Separation of Monosaccharides and Oligosaccharides [PDF]

open access: yesShipin Kexue
Carbohydrates play a vital role in food science, medicine science, life science and other fields. Carbohydrates can be divided into monosaccharides, oligosaccharides, and polysaccharides, among which monosaccharides and oligosaccharides are mostly ...
