It has been found that the cosmic-ray particles which occur in showers of small angular divergence are much more penetrating than those of the usual type of shower. The particles in such "hard showers" are clearly not electrons and are interpreted as medium and low energy mesotrons. The second maximum of the Rossi curve, which is accentuated for small-angle shower arrangements, can be accounted...

−∞ dqD(q). The scattering cross section σ thus approximately decouples into on-shell production (σp) and decay as shown in Eq. (1) for a scalar process [1]. The generalization to multiple resonances is straightforward. We use the notation of [2], Sec. 38. Based on the scales occurring in D(q), the conventional error estimate is O(Γ/M). The branching fraction for the considered decay mode is the...

When the railways were nationalized between 1906 and 1907, the skeleton of the nationwide trunk rail network was nearly completed, as mandated in the Railway Construction Act of 1892. At the end of 1907, nationalized railway lines in operation totalled 7,165 km. Construction continued and 2,677 km of line were added by the end of 1919. In addition to active line expansion, the first decade afte...

immunosuppressants require therapeutic drug monitoring because of their narrow therapeutic index and significant inter-individual variability in blood concentrations. this variability can be because of factors like drug-nutrient interactions, drug-disease interactions, renal-insufficiency, inflammation and infection, gender, age, polymorphism and liver mass. drug monitoring is widely practiced ...

general and specific combining ability of some rice lines and cultivars with irri sources were determined using the line × tester procedure (5 pure lines were crossed with 4 local cultivars as tester). parents and their progenies were planted in a randomized complete block design with three replications in the research field of iran rice research institute. traits such as yield and its componen...

We propose a model of narrow framing in insurance and test it using data from a new module we designed and fielded in the Health and Retirement Study. We show that respondents subject to narrow framing are substantially less likely to buy long-term care insurance than average. This effect is distinct from, and much larger than, the effects of cautiousness, risk aversion, or adverse selection, a...

We present randomized algorithms for some well-studied, hard combinatorial problems: the k-path problem, the p-packing of qsets problem, and the q-dimensional p-matching problem. Our algorithms solve these problems with high probability in time exponential only in the parameter (k, p, q) and using polynomial space; the constant bases of the exponentials are significantly smaller than in previou...
