Solubility prediction of high molecular weight molecules in high-pressure solvents is an interesting field of research. Sometimes the solubility data are not available for several components due to lacking of valid equipments. Therefore, an accurate prediction technique can help the researchers. According to the literature, the simple Equations of State (EoSs) such as Soave-Redlich-Kwong (SRK),...
Piezoactive porous polyvinylidene fluoride films prepared in the process based on melt extrusion with subsequent isometric annealing, uniaxial extension and thermal fixation have been studied. It was shown that two competing orientation processes -polymorphous transition of non-polar α-phase into polar piezoactive β-phase formation structure - occur during annealed films. has established degree...
In this letter, a deep neural network (DNN) aided joint source-channel (JSCC) decoding scheme is proposed for polar codes. the scheme, an integrated factor graph with unfolded structure first designed. Then DNN flooding belief propagation (FBP) algorithm based on factor, in which both source and channel scaling parameters BP are optimized better performance. Experimental results show that, FBP ...

In a recent PSA paper (2001a), as well as some other papers (1995, 2000, 2001b) and a book chapter (1999, Chapter 7), Stathis Psillos raised a number of objections against structural realism. The aim of this paper is threefold: (1) to evaluate part of Psillos’ offence on the Russellian version of epistemic structural realism (ESR); (2) to elaborate more fully what Russellian ESR involves; and (...
The ‘‘viewpoint’’ article by Dyck et al. (2007) [Dyck. M.G., Soon, W., Baydack, R.K., Legates, D.R., Baliunas, S., Ball, T.F., Hancock, L.O., 2007. Polar bears of western Hudson Bay and climate change: are warming spring air temperatures the ‘‘ultimate’’ survival control factor? Ecol. Complexity 4, 73–84. doi:10.1016/j.ecocom.2007.03.002.] suggest that factors other than climate warming are res...
A total of 341 fertilized and 37 unfertilized oocytes from 63 intracytoplasmic sperm injection (ICSI) treatment cycles were included for retrospective assessment using the Embryoscope time-lapse video system. The second polar body (pb2) extrusion occurred at 2.9±0.1 h (range 0.70-10.15 h) relative to sperm injection. All oocytes reduced in size following sperm injection (p<0.05) with shrinkage ...
this paper presents a low-cost compact planar microstrip-fed monopole antenna and its four-element array design for ultra-wideband (uwb) wireless communication and target detection applications, respectively, operating in the frequency span of 3 ghz to 11 ghz. a prototype was fabricated and then measured based on optimal parameters. the results of reflection coefficient (s11) and radiation patt...
Psoriatic Arthritis (PsA) is a seronegative, inflammatory joint disease. In most patients with PSA, skin psoriasis precedes arthritis; however, the causality is multi-factorial and many aspects related to it remain unclear. Tumor necrosis factor (TNF) plays essential role in the pathogenesis of PsA and psoriasis. Hence, the selective inhibition of TNF-α leads to significant improvement of disea...
