An oscillating, homogeneous and isotropic Universe which arises from Scalar-Tensor gravity is discussed in the linearized approach, showing that some observative evidences like the Hubble Law and the Cosmological Redshift are in agreement with the model. In this context Dark Energy appears like a pure curvature effect arising by the scalar field. PACS numbers: 04.80.Nn, 04.30.Nk, 04.50.+h

Summary Megaselia scalaris (Loew) (Diptera: Phoridae) is a synanthropic fly that lives in wide range of warmer regions globally. Although it listed as quarantine pest the Eurasian Economic Union, phytosanitary protocols have not been established. The larva feeds on moist food material and cannot grow dry matter, including cured tobacco. However, adults this species detected containers containin...

The phenology of fungal fruiting has changed in the UK over last 70 years, but whether associated mycophagous insects are able to exploit 'out season' fruit bodies is unknown. This study focused on baits can be used as a proxy examine changes insect communities. Using Agaricus bisporus bait, mushrooms were placed into two separate woodlands monthly from November 2020 July 2021. Megaselia rufipe...

In this paper, we discuss some properties of joint spectral {radius(jsr)} and  generalized spectral radius(gsr)  for a finite set of upper triangular matrices with entries in a Banach algebra and represent relation between geometric and joint/generalized spectral radius. Some of these are in scalar matrices, but  some are different. For example for a bounded set of scalar matrices,$Sigma$, $r_*...

The well-known sex-determining cascade of Drosophila melanogaster serves as a paradigm for the pathway to sexual development in insects. But the primary sex-determining signal and the subsequent step, Sex-lethal (Sxl), have been shown not to be functionally conserved in non-Drosophila flies. We isolated doublesex (dsx), which is a downstream step in the cascade, from the phorid fly Megaselia sc...

The scuttle fly, Megaselia scalaris, is often cited as a model in which to study early sex chromosome evolution because of its homomorphic sex chromosomes, low but measurable molecular differentiation between sex chromosomes, and occasional transposition of the male-determining element to different chromosomes in laboratory cultures. Counterintuitively, natural isolates consistently show sex li...
