In many cases, rivers, mountains, forests, and other so-called natural entities have value for us because they contribute to our well-being. According to the standard model of such value, they have instrumental or “service” value for us on account of their causal powers. That model tends, however, to come up short when applied to cases when nature contributes to our well-being by virtue of the religious, political, historical, personal, or mythic meanings it bears. To make sense of such cases, a new model of nature’s value is needed, one that registers the fact that nature can have constitutive value for us on account of the role it plays in certain meaningful wholes, such as a person’s sense of who he or she is.

Successful Observation

The paper introduces a new model of telepresence. First, it criticizes the standard model of presence as epistemic failure, showing it to be inadequate. It then replaces it with a new model of presence as successful observation. It further provides reasons to distinguish between two types of presence, backward and forward. The new model is then tested against two ethical issues whose nature has been modified by the development of digital information and communication technologies, namely pornography and privacy, and shown to be effective.

Rotor modeling by means of finite elements is necessary for rotordynamic calculations of industrial machines. Standard methods are available and allow forecasting rather accurately the experimental dynamic behavior of the considered machines. Anyhow, in some cases, due to the specific layout of the machine, the model made by means of these methods has to be updated to fit experimental results. In this paper, the updating of the torsional model of a steam turbogenerator is presented. Starting from some differences between the eigenfrequencies calculated using the standard model and the natural frequencies measured on-field, a modeling improvement is proposed, considering partially the dynamics of the parts usually modeled as rigid disks, with the aim to preserve the physical meaning of the model. The new model is updated and a very good fitting is obtained between eigenfrequencies and natural frequencies.

Colliding Beams

The success of the first few years of LHC operations at CERN, and the expectation of more to come as the LHC's performance improves, are already leading to discussions of what should be next for both proton–proton and electron–positron colliders. In this discussion I see too much theoretical desperation caused by the so-far-unsuccessful hunt for what is beyond the Standard Model, and too little of the necessary interaction of the accelerator, experimenter, and theory communities necessary for a scientific and engineering success. Here, I give my impressions of the problem, its possible solution, and what is needed to have both a scientifically productive and financially viable future.

Theory Of Gravity

A quantum theory of gravity, based upon a composite model of leptons and quarks, is presented. The model treats leptons and quarks as composites of three kinds of spin-[Formula: see text] particles (rishons) and/or their antiparticles. A strong color force, mediated by massless hypergluons, binds rishons and/or antirishons together to form colorless leptons or colored quarks, the fundamental particles of the Standard Model. The new model provides a qualitative understanding of the mass hierarchy of the three generations of leptons and quarks. An earlier conjecture that the residual interaction of the strong color force acting between any two colorless particles be identified with the corresponding gravitational interaction, is shown to lead approximately to Newton's law of gravitation.

Triplet Representation

A new composite model for leptons and quarks is presented. The model treats leptons and quarks as composites of three kinds of spin-½ particles (rishons), which belong to a fundamental triplet representation of a flavor SU (3) symmetry. A super-strong color-type force binds rishons together to form colorless leptons or quarks. Quarks display a valence property, which corresponds to the quark color of the Standard Model. Leptons have no valence property and are inert with respect to the super-strong color interaction. Both the strong color force and the weak interaction of the Standard Model are residual interactions of the super-strong color force in the new model.

Philosophy And Economics

AbstractA long tradition in philosophy and economics equates intelligence with the ability to act rationally—that is, to choose actions that can be expected to achieve one’s objectives. This framework is so pervasive within AI that it would be reasonable to call it the standard model. A great deal of progress on reasoning, planning, and decision-making, as well as perception and learning, has occurred within the standard model. Unfortunately, the standard model is unworkable as a foundation for further progress because it is seldom possible to specify objectives completely and correctly in the real world. The chapter proposes a new model for AI development in which the machine’s uncertainty about the true objective leads to qualitatively new modes of behavior that are more robust, controllable, and deferential to humans.

AbstractWe propose a new model of ergodic optimization for expanding dynamical systems: the holonomic setting. In fact, we introduce an extension of the standard model used in this theory. The formulation we consider here is quite natural if one wants a meaning for possible variations of a real trajectory under the forward shift. In other contexts (for twist maps, for instance), this property appears in a crucial way. A version of the Aubry–Mather theory for symbolic dynamics is introduced. We are mainly interested here in problems related to the properties of maximizing probabilities for the two-sided shift. Under the transitive hypothesis, we show the existence of sub-actions for Hölder potentials also in the holonomic setting. We analyze then connections between calibrated sub-actions and the Mañé potential. A representation formula for calibrated sub-actions is presented, which drives us naturally to a classification theorem for these sub-actions. We also investigate properties of the support of maximizing probabilities.

After the last missing piece, the Higgs particle, has probably been identified, the Standard Model of the subatomic particles appears to be a quite robust structure, that can survive on its own for a long time to come. Most researchers expect considerable modifications and improvements to come in the near future, but it could also be that the Model will stay essentially as it is. This, however, would also require a change in our thinking, and the question remains whether and how it can be reconciled with our desire for our theories to be “natural”.

It is assumed that standard model is the most successful theory of particle physics but it is not perfect. In this paper, I am interested to flash the published results of various proposals of theoretical physicists in various modes of Standard Model and beyond. There are no specifications theory to declare new model to till date, although some ideas that would modify the standard model in many ways helps to understand the existing results.

Pleiotropic Mutation

AbstractMutation-selection models provide a framework to relate the parameters of microevolution to properties of populations. Like all models, these must be subject to test and refinement in light of experiments. The standard mutation-selection model assumes that the effects of a pleiotropic mutation on different characters are uncorrelated. As a consequence of this assumption, mutations of small overall effect are suppressed. For strong enough pleiotropy, the result is a nonvanishing fraction of a population with the “perfect” phenotype. However, experiments on microorganisms and experiments on protein structure and function contradict the assumptions of the standard model, and Kimura’s observations of heterogeneity within populations contradict its conclusions. Guided by these observations, we present an alternative model for pleiotropic mutations. The new model allows mutations of small overall effect and thus eliminates the finite fraction of the population with the perfect phenotype.
