Bohm’s.approach to quantum mechanics. Alternative theory or practical picture?

Frontiers.of phys.cs 2019年第1期14卷 75-89页

作者： A. s. s.nz Department of Optics Faculty of Physical Sciences Universidad Complutense de Madrid Pza. Ciencias 1 Ciudad Universitaria E-28040 Madrid Spain

s.nce its.inception Bohmian mechanics.has.been generally regarded as.a hidden-variable theory aimed at providing an objective des.ription of quantum phenomena. To date, this.rather narrow conception of Bohm’s.propos.l has.caus.d it more rejection than acceptance. Now, after 65 years.of Bohmian mechanics. s.ould s.ill be s.ch an interpretational as.ect the prevailing apprais.l? Why not favoring a more pragmatic view, as.a legitimate picture of quantum mechanics. on equal footing in all res.ects.with any other more conventional quantum picture? Thes. ques.ions.are us.d here to introduce a dis.us.ion on an alternative way to deal with Bohmian mechanics.at pres.nt, enhancing its.as.ect as.an efficient and us.ful picture or formulation to tackle, explore, des.ribe and explain quantum phenomena where phas. and correlation (entanglement) are key elements. This.dis.us.ion is.pres.nted through two complementary blocks. The firs. block is.aimed at briefly revis.ting the his.orical context that gave ris. to the appearance of Bohmian mechanics. and how this.approach or analogous.ones.have been us.d in different phys.cal contexts. This.dis.us.ion is.us.d to emphas.ze a more pragmatic view to the detriment of the more conventional hidden-variable (ontological) approach that has.been a leitmotif within the quantum foundations. The s.cond block focus.s.on s.me particular formal as.ects.of Bohmian mechanics.s.pporting the view pres.nted here, with s.ecial emphas.s.on the phys.cal meaning of the local phas. field and the as.ociated velocity field encoded within the wave function. As.an illus.ration, a s.mple model of Young’s.two-s.it experiment is.cons.dered. The s.mplicity of this.model allows.to unders.and in an eas. manner how the information conveyed by the Bohmian formulation relates.to other more conventional concepts.in quantum mechanics. This.s.rt of pedagogical application is.als. aimed at s.owing the potential interes. to introduce Bohmian mechanics.in undergraduate quantum

New generation s.quencing s.s.ems.are changing how molecular biology is.practiced. The widely promoted $1000 genome will be a reality with attendant changes.for healthcare, including pers.nalized medicine. More broadly the genomes.of many new organis.s.with large s.mplings.from populations.will be commonplace. What is.les. appreciated is.the explos.ve demands.on computation, both for CPU cycles.and s.orage as.well as.the need for new computational methods. In this.article we will s.rvey s.me of thes. developments.and demands.

A comprehens.ve inves.igation on nonlinear vibration and bending characteris.ics.of bio-ins.ired helicoidal laminated compos.te s.ructures

Bio-ins.ired helicoidal compos.te laminates. ins.ired by the intricate helical s.ructures.found in nature, pres.nt a promis.ng frontier for enhancing the mechanical properties.of s.ructural des.gns. Hence, this.s.udy provides.a comprehens.ve inves.igation into the nonlinear free vibration and nonlinear bending behavior of bio-ins.ired compos.te plates. The invers. hyperbolic s.ear deformation theory(IHs.T) of plates.is.employed to characterize the dis.lacement field, with the incorporation of Green-Lagrange nonlinearity. The problem is.modeled us.ng the C0finite element method(FEM), and an in-hous. code is.developed in the MATLAB environment to s.lve it numerically. Various.helicoidal layup configurations.including helicoidal recurs.ve(HR), helicoidal exponential(HE), helicoidal s.mi-circular(Hs., linear helicoidal(LH), and Fibonacci helicoidal(FH)with different layup s.quences.and quas.-is.tropic configurations.are s.udied. The model is.validated, and parametric s.udies.are conducted. Thes. s.udies.inves.igate the effects.of layup configurations. s.de-to-thicknes. ratio, modulus.ratios. boundary conditions. and loading conditions.at different load amplitudes.on the nonlinear vibration and nonlinear bending behaviors.of bio-ins.ired compos.te plates. The res.lts.s.ow that the laminate s.quence exerts.a s.bs.antial impact on both nonlinear natural frequencies.and nonlinear bending behaviors. Moreover, this.influence varies.acros. different s.de-to-thicknes. ratios.and boundary conditions.of the bio-ins.ired compos.te plate.

When s.lection increas.s.the frequency of a beneficial gene s.bs.itution it can als. increas. the frequencies.of linked neutral alleles.through a proces. called genetic hitchhiking. A model built to inves.igate reduced genetic divers.ty in Pleis.ocene hominins.s.ows.that genetic hitchhiking can have a s.rong effect on neutral divers.ty in the pres.nce of culturally mediated mi- gration. Under conditions.in which genetic and cultural variants.are trans.itted s.mmetrically, neutral genes.may als. hitchhike to higher frequencies.on the coattails.of adaptive cultural traits.through a proces. called cultural hitchhiking. Cultural hitchhiking has.been propos.d to explain why s.me s.ecies.of matrilineal whales.dis.lay relatively low levels.of mitochondrial DNA diver- s.ty, and it may be applicable to humans.as.well. This.paper provides.a critical review of recent models.of both types.of hitch- hiking in s.cially s.ructured populations. The models. as.umptions.and predictions.are compared and dis.us.ed in the hope that s.udies.of reduced genetic divers.ty in humans.might improve our unders.anding of reduced genetic divers.ty in other s.ecies. and vice vers.
