In the present paper, we establish the zero-one law for an extension of the first-order predicate language with the quantifier "there exist no fewer than $rn$ elements", where $n$ is the cardinality of the model and $r$ is a rational number from the interval (0,1). As an example,...

Not an empty set though, because it holds only one value zero. Thus, when you exponentize it to powers greater than one, it still evaluates to zero. Below one; it seems like things get undefined. I heard once that 0 is like a point singularity. Please explain as simply as you can....
if it has only one vertex. For a graph G, a total forcing set is a forcing set of G inducing a subgraph with no isolated vertex. For simplicity, we write TF-set instead of total forcing set. The total forcing number of G, denoted by Ft(G), is the cardinality of a minimum TF-se...
Therefore, it is still very important to design one-dimensional SAC-OCDMA codes with excellent performance. The code family for SAC-OCDMA system continues to grow, and the choice of an appropriate code with CW or VW is still an open issue. However, the position of chips “1” in the ...
We show that there are exactly two zero-dimensional separable metric spaces which can be obtained as a countable infinite product of nowhere topologically complete absolute F σδ-spaces; one is the countable infinite product of rationals Q ∞, the other is a union of a dense copy of Q ∞...
Since all the decisions are made locally at the base stations, at most |U|(|N|+1) variables need to be exchanged at each iteration, where U is the set of users, N are the available transmission channels, and | · | denotes the cardinality operator. As we will demonstrate in Section ...
What happened: Running a PromQL query on the kube_pod_status_reason metric returns hundreds of result records, but every one has a value of zero. This occurs even with pods in failed or pending status. What you expected to happen: I woul...
rather coming from boolean vars. In this cases I can understand your take on value_counts and plotting. I have these categorials as well but I have many categoricals of cardinality in the order of tens, hundreds and even thousands. To me that makes perfectly sense and I consider them "...
