F or at least four decades, the field of psychoimmunology has attracted numerous investigators based on diverse hints linking the immune system to emotional behavior. The administration of cytokines for the treatment of various diseases is often associated with depression, which frequently accompanies autoimmune disease. Now, in PNAS, Greengard and colleagues (1) report a specific molecular pat...

We calculate photoexcitation amplitudes for all nucleon and ∆ resonances up to √ s=1.6 GeV. We use a chiral quark model including two-body exchange currents. The two-body currents give important contributions. For the ∆(1232) and the D13(1520) we observe that the individual exchange current contributions considerably cancel each other while for the P11(1440), the P33(1600), and the S11(1535) we...

We study membrane scattering in a curved space with non-zero M-momentum p11 transfer. In the low-energy short-distance region, the membrane dynamics is described by a three-dimensional N = 4 supersymmetric gauge theory. We study an n-instanton process of the gauge theory, corresponding to the exchange of n units of p11, and compare the result with the scattering amplitude computed in the low-en...

We consider an eigenvalue problem for a system in [0, 1]:        0 1 1 0 d dx + p11(x) p12(x) p21(x) p22(x) ϕ (1) (x) ϕ (2) (x) = λ ϕ (1) (x) ϕ (2) (x) ϕ (2) (0) cosh µ − ϕ (1) (0) sinh µ = ϕ (2) (1) cosh ν + ϕ (1) (1) sinh ν = 0 with constants µ, ν ∈ C. Under the assumption that p21, p22 are known, we prove a uniqueness theorem and provide a reconstruction formula for p11 and p12 from t...
