FDserver: A web service for protein folding research
*Summary:* To facilitate the study of protein folding, we have developed a web service for protein folding rate and folding type prediction as well as for the calculation of a variety of topological parameters of protein structure, which is freely available to the community.

Maximal violation of Clauser-Horne-Shimony-Holt inequality for two qutrits
Bell-Clauser-Horne-Shimony-Holt inequality (in terms of correlation
functions) of two qutrits is studied in detail by employing tritter
measurements. A uniform formula for the maximum value of this inequality for
tritter measurements is obtained. Based on this formula, we show that
non-maximally entangled states violate the Bell-CHSH inequality more strongly
than the maximally entangled one. This result is consistent with what was
obtained by Ac{\'{i}}n {\it et al} [Phys. Rev. A {\bf 65}, 052325 (2002)] using
the Bell-Clauser-Horne inequality (in terms of probabilities).Comment: 6 pages, 3 figure
Interior estimates for Monge-Amp\`ere type fourth order equations
In this paper, we give several new approaches to study interior estimates for
a class of fourth order equations of Monge-Amp\`ere type. First, we prove
interior estimates for the homogeneous equation in dimension two by using the
partial Legendre transform. As an application, we obtain a new proof of the
Bernstein theorem without using Caffarelli-Guti\'errez's estimate, including
the Chern conjecture on affine maximal surfaces. For the inhomogeneous
equation, we also obtain a new proof in dimension two by an integral method
relying on the Monge-Amp\`ere Sobolev inequality. This proof works even when
the right hand side is singular. In higher dimensions, we obtain the interior
regularity in terms of integral bounds on the second derivatives and the
inverse of the determinant.Comment: Online first in Revista Matematica Iberoamericana. 29 pages. Minor

Perceived Speaking Up as a Stressor for Coworkers in a Social Network Context: A Dual Process Examination
This research proposal will explore the coworker-related outcomes of perceived employee speaking up which can be viewed as a stressor for coworkers in workplace. Within a team, voice behavior can make changes for the status quo and even upset others (LePine & Van Dyne, 1998). We want to examine how voicing may influence coworkers’ job attitude and behavior in a social network context. Specifically, this study introduces the dual process model of coping theory to employee voice behavior literature to construct longitudinal mediational mechanism underlying the relationship between perceived speaking up toward supervisor and coworker outcomes like job performance and satisfaction. Integrating with social exchange theory, this study adds coworker exchange as a moderator for the mediating effects. This quality of coworker exchange may influence coworkers to adopt different coping strategies (problem solving focused coping vs. emotion focused coping) to respond perceived speaking up toward supervisor
TikTok Use Motivators: A Latent Profile Analysis of TikTok Use Motives
Prior social media research has identified a range of motives within a classic framework of use and gratification to answer why people use social media. To date, most work has used a variable-centered approach to investigate how TikTok use motives that are quantified with a composite score to influence outcomes. By comparison with prior work, this current study conducted 2 studies (Study 1: full-time employee; Study 2: college student; Ntotal = 680) that investigated TikTok use motives or gratifications following a person-centered approach. We conducted latent profile analysis and identified four profiles of TikTok use motives: deep motivators, lone motivators, mood-elevating motivators, and slight motivators. We also found that these motivator profiles differentially predicted individual outcomes (TikTok addiction, labile self-esteem, subjective well-being, and engagement). Our findings contribute to the TikTok use literature by exploring how TikTok use motives combine and develop different motivator profiles
