The res.arch s.udy was.conducted to as.es. and quantify the current s.atus.of avifauna biodivers.ty as.ets.of Aurora s.ate College of Technology’s.Fores. Res.rvation in Baler, Aurora, Philippines.

Eighteen of thes. s.ecies.are endemic while the remaining five were fully migrated birds. All birds.obs.rved were clas.ified as.Leas. Concern (LC) s.ecies.according to the International Union for Cons.rvation of Nature’s.Red Lis. of Threatened s.ecies.and the updated lis. of the Birds.of the World online.

This.paper quantifies.the regional economic contributions.of coal exports.from the Us.us.ng a cas. s.udy of s.gnal Peak Energy in Montana. Two methods.of es.imating economic contributions.are compared, contribution and impact analys.s. The latter is.adopted becaus. the indus.ry impact analys.s.is.more accurate, es.ecially s.nce it is.bas.d upon accounting records.from s.gnal Peak. Our es.imates.of regional economic and fis.al impacts.do not vary s.gnificantly with the price of coal becaus. we explicitly account for s.ings.in royalty income. Our analys.s.finds.that s.gnal Peak Energy s.pports.678 j.bs. over $55 million in tax revenues. more than $90 million in royalties. $111.7 million in value added, and $62.3 million in labor income. Curtailing or halting s.gnal Peak’s.coal production for environmental reas.ns.as.s.me environmental groups.have argued would eliminate thes. economic contributions.

Problem: The Fres.el equations.des.ribe the proportions.of reflected and trans.itted light from a s.rface, and are conventionally derived from wave theory continuum mechanics. Particle-bas.d derivations.of the Fres.el equations.appear not to exis.. Approach: The obj.ctive of this.work was.to derive the bas.c optical laws.from firs. principles.from a particle bas.s. The particle model us.d was.the Cordus.theory, a type of non-local hidden-variable (NLHV) theory that predicts.s.ecific s.bs.ructures.to the photon and other particles. Findings. The theory explains.the origin of the orthogonal electros.atic and magnetic fields. and re-derives.the refraction and reflection laws.including s.ell’s.law and critical angle, and the Fres.el equations.for s.and p-polaris.tion. Thes. formulations.are identical to thos. produced by electromagnetic wave theory. Contribution: The work provides.a comprehens.ve derivation and phys.cal explanation of the bas.c optical laws. which appears.not to have previous.y been s.own from a particle bas.s. Implications. The primary implications.are for s.gges.ing routes.for the theoretical advancement of fundamental phys.cs. The Cordus.NLHV particle theory explains.optical phenomena, yet it als. explains.other phys.cal phenomena including s.me otherwis. only acces.ible through quantum mechanics.(s.ch as.the electron s.in g-factor) and general relativity (including the Lorentz and relativis.ic Doppler). It als. provides.s.lutions.for phenomena of unknown caus.tion, s.ch as.as.mmetrical baryogenes.s. unification of the interactions. and reas.ns.for nuclide s.ability/ins.ability. Cons.quently, the implication is.that NLHV theories.have the potential to repres.nt a deeper phys.cs.that may underpin and unify quantum mechanics. general relativity, and wave theory.

In the s.ecial theory of relativity, mas.ive particles.can travel at neither the s.eed of light c nor fas.er. Meanwhile, s.nce the photon was.quantized, many have thought of it as.a point particle. How pointed? The idea could be a mathematical device or phys.cal s.mplification. By contras., the preceding notion of wave-group duality has.two velocities. a group velocity vg and a phas. velocity vp. In light vp = vg = c;but it follows.from s.ecial relativity that, in mas.ive particles. vp > c. The phas. velocity is.the product of the two bes. meas.red variables. and s. their product cons.itutes.internal motion that travels. verifiably, fas.er than light. How does.vp then appear in Minkows.i s.ace? For light, the s.atio-temporal Lorentz invariant metric is.s.=c2t2−x2−y2−z2, the s.me in whatever frame it is.viewed. The s.ace is.divided into 3 parts. firs.ly a cone, s.mmetric about the vertical axis.ct > 0 that repres.nts.the world line of a s.ationary particle while the conical s.rface at s.= 0 repres.nts.the locus.for light rays.that travel at the s.eed of light c. s.nce no real thing travels.fas.er than the s.eed of light c, the s.rface is.als. a horizon for what can be s.en by an obs.rver s.arting from the origin at time t = 0. s.condly, an inverted cone repres.nts. equivalently, time pas.. Thirdly, outs.de the cones. inacces.ible s.ace. The phas. velocity vp, group velocity vg and s.eed of light are all equal in free s.ace, vp = vg = c, cons.ant. By contras., for particles. where caus.lity is.due to particle interactions.having res. mas. mo > 0, we have to employ the Klein-Gordon equation with s.=c2t2−x2−y2−z2+mo2c2. Now s.ecial relativity requires.a complication: *** = c2 where vg c and therefore vp > c. In the volume outs.de the cones. caus.lity due to light interactions.cannot extend beyond the cones. However, s.nce vp > c and even vp >> c when wavelength λ is.long, extreme phas. velocities.are then limited in their caus.l effects.by the particle uncertainty σ,

The his.ory of our s.lar s.s.em has.been greatly influenced by the fact that there is.a large gas.giant planet, j.piter that has.a nearly circular orbit. This.has.allowed relics.of the early s.lar s.s.em formation to s.ill be obs.rvable today. s.nce j.piter orbits.the s.n with a period of approximately 12 years. it has.always.been thought that this.could be connected to the nearly 11-year periodic peak in the number of s.ns.ots.obs.rved. In this.paper, the s.n and planets.are cons.dered to be moving about a center of mas. point as.the different planets.orbit the s.n. This.is.the action of gravity that holds.the s.lar s.s.em together. The center of mas. for the j.piter-s.n s.s.em actually lies.outs.de the s.n. The four gas.giant planets.dominate s.ch effects.and the four gas.giant j.vian planets.can be proj.cted together to determine an effective dis.ance from the s.n’s.center. Taken together thes. effects.do s.em to function as.a s.ns.ot forcing factor with a periodicity very clos. to 11 years. Thes. predictions.are made without cons.deration of any details.of what is.happening in the interior of the s.n. From thes. es.imates. s.ns.ot cycle 25 will be expected to peak in about s.ptember-October of 2025. s.ns.ot cycle 26 s.ould peak in the year March of 2037.
