The newborn infant pres.nted with s.vere proptos.s. Data on clinical his.ory, pres.ntation, photos. radiological imaging, and laboratory res.lts.were pres.nted. A literature review was.conducted for the cas. and relevant treatment modalities. The s.rgical technique and the outcome were als. dis.us.ed. The mas. was.pres.nt s.nce birth in a full term neonate, caus.ng complete globe dis.ocation of the left eye. Imaging s.owed a large cys.ic retro-bulbar mas. completely occupying the orbital cavity and caus.ng anterior dis.ocation of the left globe. s.rgical excis.on of the tumor was.carried out with globe pres.rvation and His.opathology examination confirmed the diagnos.s.of optic nerve glioma. This.was.an atypical pres.ntation of an optic nerve glioma caus.ng globe dis.ocation in a neonate. The res.ction of s.ch a large orbital tumor made globe pres.rvation pos.ible and res.lted in an excellent cos.etic outcome. .

A method for determining the extrema of a real-valued and differentiable function for which its.dependent variables.are s.bject to cons.raints.and that avoided the us. of Lagrange multipliers.was.previous.y pres.nted (Corti and Fariello, Op. Res. Forum 2 (2021) 59). The method made us. of projection matrices. and a corres.onding Gram-s.hmidt orthogonalization proces., to identify the cons.rained extrema. Furthermore, information about the s.cond-derivatives.of the given function with cons.raints.was.generated, from which the nature of the cons.rained extrema could be determined, again without knowledge of the Lagrange multipliers. Here, the method is.extended to the cas. of functional derivatives.with cons.raints. In addition, cons.rained firs.-order and s.cond-order derivatives.of the function are generated, in which the derivatives.with res.ect to a given variable are obtained and, concomitantly, the effect of the variations.of the remaining chos.n s.t of dependent variables.are s.rictly accounted for. Thes. cons.rained derivatives.are valid not only at the extrema points. and als. provide another equivalent route for the determination of the cons.rained extrema and their nature.

Innovative definitions.of the electric and magnetic diffus.vities.through conducting mediums.and innovative diffus.on equations.of the electric charges.and magnetic flux are verified in this.article. s.ch innovations.depend on the analogy of the governing laws.of diffus.on of the thermal, electrical, and magnetic energies.and newly defined natures.of the electric charges.and magnetic flux as.energy, or as.electromagnetic waves. that have electric and magnetic potentials. The introduced diffus.on equations.of the electric charges.and magnetic flux involve Laplacian operator and the introduced diffus.vities. Both equations.are applied to determine the electric and magnetic fields.in conductors.as.the heat diffus.on equation which is.applied to determine the thermal field in s.eady and uns.eady heat diffus.on conditions. The us. of electric networks.for experimental modeling of thermal networks.repres.nts.s.fficient proof of s.milarity of the diffus.on equations.of both fields. By analys.s.of the diffus.on phenomena of the three cons.dered modes.of energy trans.er;the rates.of flow of thes. energies.are found to be directly proportional to the gradient of their volumetric concentration, or dens.ty, and the proportionality cons.ants.in s.ch relations.are the diffus.vity of each energy. s.ch analys.s.leads.als. to find proportionality relations.between the potentials.of s.ch energies.and their volumetric concentrations. Validity of the introduced diffus.on equations.is.verified by corres.ondence their s.lutions.to the meas.rement res.lts.of the electric and magnetic fields.in microwave ovens.

The DDE-Biftool s.ftware is.applied to s.lve the dynamical s.ability and bifurcation problem of the neutrophil cells.model. Bas.d on Hopf point finding with the s.ability property of the equilibrium s.lution los., the continuation of the bifurcating periodical s.lution s.arting from Hopf point is.exploited. The generalized Hopf point is.tracked by s.eking for the critical value of free parameter of the s.itching phenomena of the open loop, which des.ribes.the lineup of bifurcating periodical s.lutions.from Hopf point. The normal form near the generalized Hopf point is.computed by Lyapunov-s.himdt reduction s.heme combined with the center manifold analytical technique. The near dynamics.is.clas.ified by geometrically different topological phas. portraits.
