Trans-Sasakian 3-Manifolds with Reeb Flow Invariant Ricci Operator
Let M be a three-dimensional trans-Sasakian manifold of type ( α , β ) . In this paper, we obtain that the Ricci operator of M is invariant along Reeb flow if and only if M is an α -Sasakian manifold, cosymplectic manifold or a

Ricci Solitons in β-Kenmotsu Manifolds
The object of the present paper is to study Ricci soliton in β-Kenmotsu manifolds. Here it is proved that a symmetric parallel second order covariant tensor in a β-Kenmotsu manifold is a constant multiple of the metric tensor.

ABSTRACT The percomorph fish clade Gobioidei is a suborder that comprises over 2200 species distributed in nearly all aquatic habitats. To understand the genetics underlying their species diversification, we sequenced and annotated the genome of the loach goby, Rhyacichthys aspro, an early‐diverging group, and compared it with nine additional Gobioidei

Biodiversity in mountain soils above the treeline
ABSTRACT Biological diversity in mountain ecosystems has been increasingly studied over the last decade. This is also the case for mountain soils, but no study to date has provided an overall synthesis of the current state of knowledge. Here we fill this gap with a first global analysis of published research on cryptogams, microorganisms, and fauna in ...

ABSTRACT This paper analyses the relationship between firms' investment in green technologies and competitive performance. We take advantage of new data on the adoption of different green technologies (circular economy, technical advancements, energy savings, and efficiency gains) from a large representative sample of Italian firms.

Anti‐Lung Cancer Effects and Related Mechanisms of α‐Caryophyllene In Vitro and In Vivo
α‐Caryophyllene is a natural condiment and flavoring additive. In this study, α‐caryophyllene suppressed the proliferation of A549 cells, induced apoptosis via the mitochondrial pathway, and restricted cell metastasis in vitro. Besides, it repressed the growth of A549 transplantation tumors by causing apoptosis of tumor cells in vivo.

Moderate Laryngeal Dysplasia in the Context of Classification Systems and Clinical Decision Making
There is still an ongoing debate about the classification of laryngeal dysplasia. In a large retrospective analysis of 392 patients, the progression of dysplasia and the risk of a de novo occurrence of invasive carcinoma were evaluated. Here especially the high rate of occurrence of invasive carcinoma in the group of moderate dysplasia with 44% is of ...
