Characterization of the Early Life Microbiota Development and Predominant Lactobacillus Species at Distinct Gut Segments of Low- and Normal-Birth-Weight Piglets

Frontiers in Microbiology, 2019
Microbial exposure during early life plays a pivotal role in modulating the health and intestinal development of the host. Our recent study showed that the low-birth-weight (LBW) piglets harbored a different fecal microbiota compared to normal-birth ...

The Process of Changes in Size Distribution of Manufacturing Firms in Iran [PDF]

پژوهشهای اقتصادی, 2013
Although many firms enter into the market in completely different sizes, recent facts show that the size distribution of new-entrant firms tend to more homogeneity than disparity over time.

Massive spin-3/2 models in D=2+1

Physics Letters B, 2017
We have demonstrated that the fermionic part of the so called “New Topologically Massive Supergravity”, which is of third order in derivatives, is classically equivalent to self-dual models of lower order in derivatives, forming then a sequence of ...

Protein expression of the tear film of domestic cats before and after inoculation with Toxoplasma gondii

BMC Veterinary Research, 2021
Background Tear film (TF) helps maintain and protect ocular function against damage to the ocular surface. Proteins are one of its main constituents, whose expression pattern can be used as a biomarker of ocular changes and systemic diseases.

J/\psi dissociation cross sections in a relativistic quark model

, 2003
We calculate the amplitudes and the cross sections of the charm dissociation processes J/\psi \pi => D \bar D, D* \bar D, D \bar D*, D* \bar D* within a relativistic constituent quark model.

HFS interval of the $2s$ state of hydrogen-like atoms and a constraint on a pseudovector boson with mass below $1\;$keV$/c^2$

, 2010
A constraint on a long-range spin-dependent interaction $\alpha^{\prime\prime}({\bf s}_1\cdot{\bf s}_2)\,{\rm e}^{-\lambda r}/r$, which can be induced by a pseudovector light boson, is presented.
