B-cell development: one problem, multiple solutions.
Interspecies variations in the processes of B-cell development and repertoire generation contrast with the greater consistency of T-cell development. B-cell development in mice and humans, with postnatal B-cell generation of new repertoire in the bone marrow throughout life, is regarded as the 'standard' pattern. In contrast, accounts of B cells in birds, sheep, cattle, rabbits and pigs (the 'o...
متن کاملOne Reason, Several Logics
Humans have used arguments for defending or refuting statements long before the creation of logic as a specialized discipline. This can be interpreted as the fact that an intuitive notion of “logical consequence” or a psychic disposition to articulate reasoning according to this pattern is present in common sense, and logic simply aims at describing and codifying the features of this spontaneou...
متن کاملMultiple solutions of a generalized one-dimensional Bratu problem
Nonlinear two-point boundary value problems (BVPs) may have none or more than one solution. For the singularly perturbed two-point BVP εu′′ + 2u′ + f (u) = 0, 0 < x < 1, u(0) = 0, u(1) = 0, a condition is given to have one and only one solution; also cases of more solutions have been analyzed. After attention to the form and validity of the corresponding asymptotic expansions, partially based o...
متن کاملStructure of Stable Solutions of a One-dimensional Variational Problem
We prove the periodicity of all H-local minimizers with low energy for a one-dimensional higher order variational problem. The results extend and complement an earlier work of Stefan Müller which concerns the structure of global minimizer. The energy functional studied in this work is motivated by the investigation of coherent solid phase transformations and the competition between the effects ...
متن کاملRivest Problem Set 2 Solutions Problem 1 - 1 . One - Time Pads
0 ≤ xi ⊕ yi < 16 for all individual bytes i ∈ [0, 191]. Therefore, by taking two encoded messages x′ = x ⊕ p and y′ = y⊕ q and XORing them together, we get x′⊕ y′ = (x⊕ y)⊕ (p⊕ q), which in turn equals x⊕ y if they used the same pad p = q. So, if all bits of x′ ⊕ y′ are less than 16, we can be reasonably certain that the same OTP was used; otherwise, we can be fully certain that different OTPs ...
