    NEW TRIAL - USE OF TESTIMONY OF JURORS TO SET ASIDE VERDICT

    Get PDF
    Whether or not testimony of a juror is admissible for the purpose of setting aside a verdict is a question upon which the cases are in conflict. Much of the contrariety of opinion is due to a failure of courts to distinguish between the two basic factual situations which present the problem. The juror\u27s testimony may be sought to be introduced to show either: (1) that, due to some misunderstanding, his own thought processes were misdirected in arriving at his final vote; or, (2) that he observed the open misconduct of a fellow juror. At the outset it should be noted that the majority rule is to exclude all testimony of jurors whether it goes to prove misunderstanding or misconduct. However, the American Law Institute in its Model Code of Evidence adopted a rule correctly recognizing the distinction pointed out and squarely opposing the majority rule as to misconduct. It stated that every member of the jury may testify to any material matter, including any statement or conduct ... of any member of the jury ... whether during deliberations of the jury, or in reaching or reporting its verdict .... Because of the number of eminent authorities who aided in this draft it is appropriate to reconsider the policies lying behind the majority rule

    EVIDENCE - OFFICE CUSTOM TO PROVE FACT OF MAILING

    Plaintiff agreed to purchase land from defendant by a contract in which it was stipulated that the performance of the mechanics of purchase would be completed through a third party, Webster. Plaintiff deposited the purchase money with Webster with instructions to deliver it to defendant only after he (Webster) had, inter alia, procured a policy of title insurance. Webster absconded with the funds. In a suit to determine the incidence of loss, plaintiff sought to prove that Webster had procured the policy before he absconded and therefore held the purchase money as agent for defendant. The proof that plaintiff relied upon to establish that Webster had received such a policy was: (1) that X Insurance Company had received an application from Webster for insurance and that the policy had been properly filled out; and (2) that it was the office custom of X Insurance Company to mail such policies when completed. Defendant claimed there had been insufficient proof of mailing. The lower court rendered judgment for defendant. On appeal, held, affirmed. Proof of an office custom with respect to mailing is insufficient to prove posting without establishing compliance with that custom in the specific instance. Lieb v. Webster, (Wash. 1948) 190 P. (2d) 701

    The spectrum of N2O between 800 and 5200 cm(-1)

    Get PDF
    An atlas of N2O lines between 800 and 5200/cm obtained from low-pressure, long-path-length samples at 296K is presented. Many of the line centers were marked and their positions were tabulated. The peak absorptances of the weaker lines in the atlas are similar to those expected in an extreme path through the atmosphere

    Interacting Dark Matter and Dark Energy

    Full text link
    We discuss models for the cosmological dark sector in which the energy density of a scalar field approximates Einstein's cosmological constant and the scalar field value determines the dark matter particle mass by a Yukawa coupling. A model with one dark matter family can be adjusted so the observational constraints on the cosmological parameters are close to but different from what is predicted by the Lambda CDM model. This may be a useful aid to judging how tightly the cosmological parameters are constrained by the new generation of cosmological tests that depend on the theory of structure formation. In a model with two families of dark matter particles the scalar field may be locked to near zero mass for one family. This can suppress the long-range scalar force in the dark sector and eliminate evolution of the effective cosmological constant and the mass of the nonrelativistic dark matter particles, making the model close to Lambda CDM, until the particle number density becomes low enough to allow the scalar field to evolve. This is a useful example of the possibility for complexity in the dark sector.Comment: 15 pages, 6 figures; added a reference and a minor correctio

    A double-lined spectroscopic orbit for the young star HD 34700

    Full text link
    We report high-resolution spectroscopic observations of the young star HD 34700, which confirm it to be a double-lined spectroscopic binary. We derive an accurate orbital solution with a period of 23.4877 +/- 0.0013 days and an eccentricity of e = 0.2501 +/- 0.0068. The stars are found to be of similar mass (M2/M1 = 0.987 +/- 0.014) and luminosity. We derive also the effective temperatures (5900 K and 5800 K) and projected rotational velocities (28 km/s and 22 km/s) of the components. These values of v sin i are much higher than expected for main-sequence stars of similar spectral type (G0), and are not due to tidal synchronization. We discuss also the indicators of youth available for the object. Although there is considerable evidence that the system is young --strong infrared excess, X-ray emission, Li I 6708 absorption (0.17 Angstroms equivalent width), H alpha emission (0.6 Angstroms), rapid rotation-- the precise age cannot yet be established because the distance is unknown.Comment: 17 pages, including 2 figures and 2 tables.

    Stiff Stability of the Hydrogen atom in dissipative Fokker electrodynamics

    Full text link
    We introduce an ad-hoc electrodynamics with advanced and retarded Lienard-Wiechert interactions plus the dissipative Lorentz-Dirac self-interaction force. We study the covariant dynamical system of the electromagnetic two-body problem, i.e., the hydrogen atom. We perform the linear stability analysis of circular orbits for oscillations perpendicular to the orbital plane. In particular we study the normal modes of the linearized dynamics that have an arbitrarily large imaginary eigenvalue. These large eigenvalues are fast frequencies that introduce a fast (stiff) timescale into the dynamics. As an application, we study the phenomenon of resonant dissipation, i.e., a motion where both particles recoil together in a drifting circular orbit (a bound state), while the atom dissipates center-of-mass energy only. This balancing of the stiff dynamics is established by the existence of a quartic resonant constant that locks the dynamics to the neighborhood of the recoiling circular orbit. The resonance condition quantizes the angular momenta in reasonable agreement with the Bohr atom. The principal result is that the emission lines of quantum electrodynamics (QED) agree with the prediction of our resonance condition within one percent average deviation.Comment: 1 figure, Notice that Eq. (34) of the Phys. Rev. E paper has a typo; it is missing the square Brackets of eq. (33), find here the correct e

    Quasienergy Spectroscopy of Excitons

    We theoretically study nonlinear optics of excitons under intense THz irradiation. In particular, the linear near infrared absorption and resonantly enhanced nonlinear sideband generation are described. We predict a rich structure in the spectra which can be interpreted in terms of the quasienergy spectrum of the exciton, via a remarkably transparent expression for the susceptibility, and show that the effects of strongly avoided quasienergy crossings manifest themselves directly, both in the absorption and transmitted sidebands.Comment: 4 pages RevTex, 3 eps figs included, as publishe
