Dr. John George Gehring and His Bethel Clinic: Pragmatic Therapy and Therapeutic Tourism

During the first quarter of the twentieth century, Dr. John George Gehring treated hundreds of patients for stress, anxiety, and depression at his home in Bethel,Maine. Employing a pragmatic mix of hypnotism, medication, talk therapy, and behavior modification, Gehring attracted famous writers, academics, philanthropists, politicians, and socialites from around the U.S. Although he wrote and spoke about his methods, Gehring did not found a school of therapy or have a great deal of professional influence, but he had a sizeable impact on the state of Maine through the philanthropy of one of his patients, William Bingham II, whose visits to Gehring’s Bethel clinic are part of a pattern of therapeutic tourism that continues to the present

Post-natal Survival of Raccoons in Relation to Female Age and Denning Behavior

We measured post-natal survival of radio-collared raccoons 1-5 months old in southwest Iowa, 1988-1989. We compared survival of young nurtured by yearling and adult females and related den site selection to survival functions using proportional hazards models. Adult females used upland and farmstead habitats note frequently than yearlings, whereas yearling females used lowland habitats note frequently. Tree cavities and beds on the ground were used most frequently. Adult females denned in buildings 13% of the time and in holes in the ground 9.5% of the time, whereas yearlings frequently tested with litters in beds on the ground (31%). Microhab1tat characteristics including such factors as tree size, surrounding vegetation, and den characteristics had no influence on use. We observed 9 mortalities of 64 earmarked young, 4 caused by dogs, the remaining including vehicle collisions, predation, and disease. All mortalities occurred after litters moved from their natal den to a post-natal den site. We could not show significant differences in survival of young nurtured by yearling and adult females and the best estimate of post-natal survival of raccoons from 22 May to 15 September was 0.65. Post-natal survival was positively influenced by the variety of habitats and den types used by females and their young. Denning habitat selection and post-natal survival of young, particularly those of adult females, may have an important influence on population levels

On the number of representations providing noiseless subsystems

This paper studies the combinatoric structure of the set of all representations, up to equivalence, of a finite-dimensional semisimple Lie algebra. This has intrinsic interest as a previously unsolved problem in representation theory, and also has applications to the understanding of quantum decoherence. We prove that for Hilbert spaces of sufficiently high dimension, decoherence-free subspaces exist for almost all representations of the error algebra. For decoherence-free subsystems, we plot the function $f_d(n)$ which is the fraction of all $d$-dimensional quantum systems which preserve $n$ bits of information through DF subsystems, and note that this function fits an inverse beta distribution. The mathematical tools which arise include techniques from classical number theory.Comment: 17 pp, 4 figs, accepted for Physical Review

Novel instrumented frame for standing exercising of users with complete spinal cord injuries

This paper describes a Functional Electrical Stimulation (FES) standing system for rehabilitation of bone mineral density (BMD) in people with Spinal Cord Injury (SCI). BMD recovery offers an increased quality of life for people with SCI by reducing their risk of fractures. The standing system developed comprises an instrumented frame equipped with force plates and load cells, a motion capture system, and a purpose built 16-channel FES unit. This system can simultaneously record and process a wide range of biomechanical data to produce muscle stimulation which enables users with SCI to safely stand and exercise. An exergame provides visual feedback to the user to assist with upper-body posture control during exercising. To validate the system an alternate weight-shift exercise was used; 3 participants with complete SCI exercised in the system for 1 hour twice-weekly for 6 months. We observed ground reaction forces over 70% of the full body-weight distributed to the supporting leg at each exercising cycle. Exercise performance improved for each participant by an increase of 13.88 percentage points of body-weight in the loading of the supporting leg during the six-month period. Importantly, the observed ground reaction forces are of higher magnitude than other studies which reported positive effects on BMD. This novel instrumentation aims to investigate weight bearing standing therapies aimed at determining the biomechanics of lower limb joint force actions and postural kinematics

Polynomial Identities, Indices, and Duality for the N=1 Superconformal Model SM(2,4\nu)

We prove polynomial identities for the N=1 superconformal model SM(2,4\nu) which generalize and extend the known Fermi/Bose character identities. Our proof uses the q-trinomial coefficients of Andrews and Baxter on the bosonic side and a recently introduced very general method of producing recursion relations for q-series on the fermionic side. We use these polynomials to demonstrate a dual relation under q \rightarrow q^{-1} between SM(2,4\nu) and M(2\nu-1,4\nu). We also introduce a generalization of the Witten index which is expressible in terms of the Rogers false theta functions.Comment: 41 pages, harvmac, no figures; new identities, proofs and comments added; misprints eliminate
