Isomorphism and Fuzzy Subspaces
This work provides a necessary and sufficient condition for the isomorphism of two fuzzy subspaces in terms of their dimensions....
Context Protecting Privacy Preservation in Ubiquitous Computing
In ubiquitous computing domain context awareness is an important issue. So, in ubiquitous computing, mere protection of message confidentiality is not sufficient for most of the applications where context-awareness can lead to near deterministic idea...
Optimal and Resilient Pheromone Utilization in Ant Foraging
Pheromones are a chemical substance produced and released by ants as means of communication. In this work we present the minimum amount of pheromones necessary and sufficient for a colony of ants (identical mobile agents) to deterministically find a...
Mailles et ensembles de Sidon
Grid condition and Sidon sets. The grid condition stated by the author in 1957 as a necessary condition for a set of integers to be a Sidon set is neither improvable nor sufficient ; explanations and stronger statements are provided....
On all real zeros for a new class of the even entire function
In this article we propose a new class of the even entire function connected with the product and series with the real coefficients. We address a sufficient condition for all real zeros for it. As a typical example, we give an answer to the problem o...
Fundamental gerbes
For a class of affine algebraic groups $\mathcal C$ over a field, we define the notions of $\mathcal C$-fundamental gerbe of a fibered category, generalizing what we had done in arXiv:1204.1260 for finite group schemes. We give sufficient conditions...
A relative Shafarevich theorem
Suppose given a Galois etale cover Y -> X of proper non-singular curves over an algebraically closed field k of prime characteristic p. Let H be its Galois group, and G any finite extension of H by a p-group P. We give necessary and sufficient cond...
Reply to: Assessing the precision of morphogen gradients in neural tube development
In a recent article [Vetter and Iber, Nat. Commun. 13, 1145 (2022)], we demonstrated that single morphogen gradients in the developing mouse neural tube can carry sufficient positional accuracy to explain the patterning precision of progenitor domain...
Fanaticism | psychology | Britannica
prejudice, adverse or hostile attitude toward a group or its individual members, generally without just grounds or before sufficient evidence. It is characterized by irrational, stereotyped beliefs.
Improving Neural Machine Translation of Indigenous Languages with Multilingual Transfer Le…
Machine translation (MT) involving Indigenous languages, including those possibly endangered, is challenging due to lack of sufficient parallel data. We describe an approach exploiting bilingual and multilingual pretrained MT models in a transfer lea...
An Optimal Realization Algorithm for Bipartite Graphs with Degrees in Prescribed Intervals
We consider the problem of constructing a bipartite graph whose degrees lie in prescribed intervals. Necessary and sufficient conditions for the existence of such graphs are well-known. However, existing realization algorithms suffer from large runni...
Null geodesic incompleteness of spacetimes with no CMC Cauchy surfaces
Chruściel, Isenberg, and Pollack constructed a class of vacuum cosmological spacetimes that do not admit Cauchy surfaces with constant mean curvature. We prove that, for sufficiently large values of the gluing parameter, these examples are both futu...
Optimal Resource Dedication in Grouped Random Access for Massive Machine-Type Communicatio…
The high risk of random access collisions leads to huge challenge for the deployment massive Machine-Type Communications (mMTC), which cannot be sufficiently overcome by current solutions in LTE/LTE-A networks such as the extended access barring (EAB...
Locality and universality in gravitational anomaly cancellation
We obtain necesary and sufficient conditions for gravitational anomaly cancellation. We show that perturbative gravitational anomalies can never be cancelled. In a similar way, in dimensions $n\neq3\operatorname{mod}4$ it is impossible to cancell glo...
Stability of rubidium molecules in the lowest triplet state
Experiments involving ultracold molecules require sufficiently long lifetimes, which can be very short for excited rovibrational states in the molecular potentials. For alkali atoms such as rubidium, a lowest rovibrational molecular state can both be...
Gels under stress: the origins of delayed collapse
Attractive colloidal particles can form a disordered elastic solid or gel when quenched into a two-phase region, if the volume fraction is sufficiently large. When the interactions are comparable to thermal energies the stress-bearing network within...
Trapping and localization of particles by a potential well deepening with time
The universal mechanism of trapping and localization of sufficiently slow-speed particles by a potential well deepening with time is established on the basis of fundamental relations of classical mechanics. Such wells may be created for a wide range...

A continuous-variable approach to the spectral properties and quantum states of the two-co…
A bosonic gas formed by two interacting species trapped in a double-well potential features macroscopic localization effects when the interspecies interaction becomes sufficiently strong. A repulsive interaction spatially separates the species into d...
