Photochromic Materials. In their Communication (e202214202), Lars Heinke et al. report nanoporous films with oriented arrays of molecular motors for light-controlled adsorption and diffusion.

The LArge-scale Reservoir Simulator (LARS) has been previously developed to study hydrate dissociation in hydrate-bearing systems under in-situ conditions. In the present study, a numerical framework of equations state describing formation at equilibrium conditions elaborated and integrated with flow transport simulator investigate multi-stage experiment undertaken LARS. A verification implemen...

We extend the results of a work by L. Hörmander [9] concerning the resolution of the characteristic Cauchy problem for second order wave equations with regular first order potentials. The geometrical background of this work was a spatially compact spacetime with smooth metric. The initial data surface was spacelike or null at each point and merely Lipschitz. We lower the regularity hypotheses o...

The theory of gerotranscendence, a developmental theory of positive aging was proposed by Lars Tornstam in 1989. It was based on the empirical researches done by him in late 1970s and early 1980s [4] and work of other theorists [5,6]. Tornstam began to explore aging with a phenomenological qualitative approach. 50 participants aged between 52 to 97 years were interviewed after a lecture by Lars...

Two-sector models with traded and non-traded goods have problems accounting for the stylized fact that the real exchange rate appreciates and consumption booms for several years following trade liberalization, or exchange-rate-based stabilization programs, in small open economies. The paper investigates some possible solutions to this ‘price-consumption puzzle’and evaluates their quantitative i...

1.1. Linear Algebra. Let F = R or F = C and let V be a vector space over F. A finite dimensional vector space over R (C) is isomorphic to Rn (Cn) for some n, where Rn = {x = (x1, . . . , xn)} for xi ∈ R and Cn = {z = (z1, . . . , zn)} for zi ∈ Cn. On Rn, the standard Euclidean inner product is given by 〈x, y〉 = ∑ xiyi and the Euclidean norm is given by ||x|| = 〈x, x〉 2 . On Cn the standard Herm...

The Leipziger allergy risk study (LARS) investigated, during a period of five years, the influence of a typical indoor contaminant burden on the development of allergies and upper respiratory tract infections in children with an allergy-risk. During the third year of life, biomonitoring with the focus on passive smoking was carried out. Therefore, typical tobacco smoke related indoor volatile o...

In this paper the block cipher RC6 is analysed. RC6 is submitted as a candidate for the Advanced Encryption Standard, it has 128-bit blocks and supports keys of 128, 192 and 256 bits, and is an iterated 20-round block cipher. Here it is shown that versions of RC6 with 128-bit blocks can be distinguished from a random permutation with up to 15 rounds; for some weak keys up to 17 rounds. Moreover...
