We investigate generators of local transformations in the covariant canonical formalism (CCF). The CCF treats space and time on an equal footing regarding differential forms as basic variables. conjugate $\pi_A$ are defined derivatives Lagrangian $d$-form $L(\psi^A, d\psi^A)$ with respect to $d\psi^A$, namely $\pi_A := \partial L/\partial d\psi^A$, where $\psi^A $ $p$-form dynamical fields. for...

The LHCb collaboration has detected a new hidden-charm pentaquark with the quantum numbers of $\mathrm{\ensuremath{\Lambda}}$ baryon: ${P}_{\ensuremath{\psi}s}^{\mathrm{\ensuremath{\Lambda}}}(4338)$. This will be interpreted as ${\overline{D}}_{s}{\mathrm{\ensuremath{\Lambda}}}_{c}\ensuremath{-}\overline{D}{\mathrm{\ensuremath{\Xi}}}_{c}$ resonance within contact-range theory. Here we briefly c...

In this study, porous silicon (PSi) was prepared and tested as an extended gate field-effect transistor (EGFET) for pH sensing. The prepared PSi has pore sizes in the range of 500 to 750 nm with a depth of approximately 42 µm. The results of testing PSi for hydrogen ion sensing in different pH buffer solutions reveal that the PSi has a sensitivity value of 66 mV/pH that is considered a super Ne...

One-year-old rooted cuttings of olive (Olea europaea L. cvs. Frantoio and Leccino) were grown either hydroponically or in soil in a greenhouse. Plants were exposed to NaCl treatments (0, 100, and 200 mM) for 35 days, followed by 30 to 34 days of relief from salt stress to determine whether previously demonstrated genotypic differences in tolerance to salinity were related to water relations par...

In this paper, the notion of $psi -$weak contraction cite{Rhoades} isextended to fuzzy metric spaces. The existence of common fixed points fortwo mappings is established where one mapping is $psi -$weak contractionwith respect to another mapping on a fuzzy metric space. Our resultgeneralizes a result of Gregori and Sapena cite{Gregori}.

The notion of generalized locally bounded $I$-topological vectorspaces is introduced. Some of their important properties arestudied. The relationship between this kind of spaces and thelocally bounded $I$-topological vector spaces introduced by Wu andFang [Boundedness and locally bounded fuzzy topological vectorspaces, Fuzzy Math. 5 (4) (1985) 87$-$94] is discussed. Moreover, wealso use the fam...

Perceived social isolation (PSI) is a deficit in normal human social interaction, which has been associated with negative health outcomes. However, the precise mechanisms through which PSI influences human health are not fully known. This review aims at bringing out what is known about these pathways through which social isolation affects human health. We searched PubMed, Medical Literature Ana...
