Bounding the complexity of advice functions
[1992] Proceedings of the Seventh Annual Structure in Complexity Theory Conference, 1995 It was known that every set A in P/poly has an advice function in PF(¿P2(A)). This note shows that A also has an advice function in PF (NP(A) ¿¿p3). From this new bound, it is shown that separating ¿P2 and ¿p2 relative to a set in P/poly is as hard as obtaining the same separation, unrelativized.

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Stochastic Optimal Growth with Bounded or Unbounded Utility and with Bounded or Unbounded Shocks [PDF]
This paper studies a one-sector stochastic optimal growth model with i.i.d. productivity shocks in which utility is allowed to be bounded or unbounded, the shocks are allowed to be bounded or unbounded, and the production function is not required to ...

A new proof of the Krzyz conjecture for n = 3 [PDF]
Известия Саратовского университета. Новая серия: Математика. Механика. ИнформатикаThe purpose of this paper is to solve the problem of the sharp estimation of the modulus of the third Taylor coefficient on the class of holomorphic bounded nonvanishing in the unit disk functions (hereafter referred to as the class of bounded ...

FEBS Letters, EarlyView.Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Simon's Bounded Rationality. Origins and use in economic theory [PDF]
The paper aims to show how Simon's notion of bounded rationality should be interpreted in the light of its connection with artificial intelligence. This connection points out that bounded rationality is a highly structured concept, and sheds light on ...

Publicaciones en Ciencias y Tecnología, 2016 In this paper we introduce the notion of “function of second bounded variation” in the sense of Shiba, and we show that if a superposition operator applies the space of all such functions on itself and it is uniformly bounded, then its generating ...

Multilinear Square Functions with Kernels of Dini’s Type
Journal of Function Spaces, 2016 Let T be a multilinear square function with a kernel satisfying Dini(1) condition and let T⁎ be the corresponding multilinear maximal square function. In this paper, first, we showed that T is bounded from L1×⋯×L1 to L1/m,∞. Secondly, we obtained that if

FEBS Letters, EarlyView.How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...
