Various routine disclosure statements relating to the performance of ultrasound (US) during COVID-19 pandemic are finding their way into radiology reports. These usually suggest that US examinations pandemic, or on a positive patient, somehow limited and urge clinicians reflect these considerations when accepting However, such generally unhelpful not consistent with realities current clinical p...

It is shown that every regular electromagnetic field in vacuum identically satisfy Maxwell equations a new manifold where the roles of space and time have been exchanged. The metric Lorentzian, depends on particular solution forces flow to tilt somehow direction lines. We give detailed description transformation discuss several its properties, both algebraic differential settings. Examples are ...

W-representation is a miraculous possibility to define non-perturbative (exact) partition function as an exponential action of somehow integrated Ward identities on unity. It well known for numerous eigenvalue matrix models, when the relevant operators are kind W-operators: Hermitian model with Virasoro constraints, it W3-like operator, and so on. We extend this statement monomial generalized K...

When two droplets with different surface tensions collide, the shape evolution of merging is asymmetric. Using experimental and numerical techniques, we reveal that this asymmetry caused by asymmetric capillary waves, which are result droplets. We show enhanced increasing tension difference, suppressed inertia colliding Furthermore, study waves in limit no inertia. not directly Marangoni forces...

We consider the higher order Schrödinger operator H=(−Δ)m+V(x) in n dimensions with real-valued potential V when n>2m, m∈N. adapt our recent results for m>1 to show that wave operators are bounded on Lp(Rn) full range 1≤p≤∞ both even and odd without assuming is small. The approach used works distinguishing cases, captures endpoints p=1,∞, somehow simplifies low energy argument classical case of...

In this essay, hegemony in traditional Marxism is posited as a social ontology based on overcoming the alienation of masses. The aim to produce full realization through work proletariat one specific political subject, collective version bourgeois subject. emancipation marks self-realization subject history, that somehow imposes itself alienated forms capitalism. On other hand, poshegemony thoug...

objective: it has been suggested that low frequency stimulation (lfs) exerts its inhibitory effect on epileptogenesis through adenosine receptors activation. in the present study, effect of different lfs frequencies on a1 and a2a receptors gene expression was investigated in perforant path kindled seizures. materials and methods: animals were kindled by perforant path stimulation. afterdischarg...

The pandemic’s impacts on European electricity markets have been enormous, especially in countries with abundant low marginal costs of production like France. This article provides an in-depth quantitative study the crisis French sector. During first lockdown episode, France has experienced unparalleled reductions demand (?12%) and wholesale prices (?45%) resulting gross revenue losses 1.3 bill...
