We find properties of topological spaces which are not shared by disjoint unions in the absence of some form of the Axiom of Choice. Introduction and Terminology This is a continuation of the study of the roll the Axiom of Choice plays in general topology. See also [vd], [gt], [wgt], and [hkrr]. Our primary concern will be the use of the axiom of choice in proving properties of disjoint unions ...

We consider the problem of basing Oblivious Transfer (OT) and Bit Commitment (BC), with information theoretic security, on seemingly weaker primitives. We introduce a general model for describing such primitives, called Weak Generic Transfer (WGT). This model includes as important special cases Weak Oblivious Transfer (WOT), where both the sender and receiver may learn too much about the other ...

We address the problem of detecting characteristic patterns in highly dynamic information networks (e.g., a retweet graph). We introduce a scalable approach based on set-system discrepancy. By implicitly labeling each network-edge with the sequence of times in which its two endpoints connect, we view an entire information network as a set-system. This view allows us to use combinatorial discrep...

Abstract Crape myrtle (Lagerstroemia indica) is a globally used ornamental woody plant and the representative species of Lagerstroemia. However, studies on evolution genomic breeding L. indica were hindered by lack reference genome. Here, we assembled first high-quality genome using PacBio combined with Hi-C scaffolding to anchor 329.14 Mb assembly into 24 pseudochromosomes. We detected previou...

Delivering bad news or negative information can be an unpleasant task; therefore people often either postpone it or mitigate its effect through positive distortion. Yet delivering (and receiving) timely and accurate negative information can be critical for performance improvement and organizational learning. This paper investigates the possibility that computer-mediated communication can increa...

Ion transport properties of grape root lipids were measured as liquid-membrane permeability. Phosphatidyloholine exchanged chloride very slowly against carbonate and bicarbonate buit more rapidly against nitrate, phosphate, and sulfate. Exchange of chloride against nitrate was rather low for the phosphatidylcholine and phosphatidylethanolamine lipid fraotions; monogalactose diglyceride was by f...

We describe a Hopf algebraic approach to the Grothendieck ring of representations of subgroups Hπ of the general linear group GL(n) which stabilize a tensor of Young symmetry {π}. It turns out that the representation ring of the subgroup can be described as a Hopf algebra twist, with a 2-cocycle derived from the Cauchy kernel 2-cocycle using plethysms. Due to Schur-Weyl duality we also need to ...

We have determined an age T = 1.87 AE for Nakhla and an initial s7Sr/S%r, I -0.7028. A rather thorough Sr equilibration took place at this time between all the phases of this meteorite, but there is clear evidence of somewhat incomplete isotopic equilibrium during the 1.87 AE event, which is not consistent with the derivation of Nakhla from a magma at this time. Nakhla has a young model age of ...
