We present an extension of a non-iterative, partitioned method previously designed and used to model the interaction between incompressible, viscous fluid thick elastic structure. The original is based on Robin boundary conditions it features easy implementation unconditional stability. However, sub-optimally accurate in time, yielding only O(Δt12) rate convergence. In this work, we propose imp...

In this work we develop fully discrete (in time and space) numerical schemes for two-dimensional incompressible fluids with mass diffusion, also so-called Kazhikhov-Smagulov models. We propose at most H1-conformed finite elements (only globally continuous functions) to approximate all unknowns (velocity, pressure and density), although the limit density (solution of continuous problem) will hav...

An automatic and easy to implement transformation of conditional term rewrite systems into computationally equivalent unconditional term rewrite systems is presented. No special support is needed from the underlying unconditional rewrite engine. Since unconditional rewriting is more amenable to parallelization, our transformation is expected to lead to efficient concurrent implementations of re...

Deep generative neural networks have proven effective at both conditional and unconditional modeling of complex data distributions. Conditional generation enables interactive control, but creating new controls often requires expensive retraining. In this paper, we develop a method to condition generation without retraining the model. By post-hoc learning latent constraints, value functions that...

BACKGROUND Unconditional regard refers to the feeling that one is accepted and valued by others without conditions. Psychological theory suggests that experiences of unconditional regard lead children to feel that they are valuable despite setbacks. We hypothesized that reflecting on experiences of unconditional regard would buffer children's negative self-feelings (eg, shame, insecurity, power...

We carry out a rigorous error analysis of the first-order semi-discrete (in time) consistent splitting scheme coupled with generalized scalar auxiliary variable (GSAV) approach for Navier-Stokes equations no-slip boundary conditions. The is linear, unconditionally stable, and only requires solving sequence Poisson type at each time step. By using build-in unconditional stability GSAV approach, ...

We give counterexamples to a conjecture of Bourgain, Casazza, Lin-denstrauss and Tzafriri that if X has a unique unconditional basis (up to permutation) then c 0 (X) also has a unique unconditional basis. We also give some positive results including a simpler proof that c 0 (ℓ 1) has a unique unconditional basis and a proof that c 0 (ℓ N n p n) has a unique unconditional basis when p n ↓ 1, N n...

This article investigates the determinants of generosity in an experiment on charity to real-life welfare recipients. It tests the effects of various measures of unconditional altruism and conditional or reciprocal altruism. The results show strong support for conditional or reciprocal altruism. However, people who are self-reported unconditional altruists make offers that are highly elastic wi...

This paper considers a modular grad-div stabilization method for approximating solutions of the time-dependent Boussinesq model non-isothermal flows. The proposed adds minimally intrusive step to an existing code, with key idea being that penalization divergence errors, is only in extra (i.e. nothing added original equations). provides full mathematical analysis by proving unconditional stabili...
