The study of nonpositively curved spaces goes back to the discovery of hyperbolic space, the work of Hadamard around 1900, and Car-tan's work in the 20's. These spaces play a signiicant role in many areas: Lie group theory, combinatorial and geometric group theory, dynamical systems, harmonic maps and vanishing theorems, geometric topology, Kleinian group theory, and Teichm uller theory. In som...

This paper addresses the question of how to increase local coherence in summaries of multi-party conversations. Due to the interactive nature of dialogues, local regions of coherence often stretch across diierent speakers, as for instance in question-answer pairs. We present an approach to automatically detect those regions of local coherence and evaluate the resulting summaries' uency and info...

The monoclonal antibody, RA3-2C2, appears to be specific for cells within the B cell lineage. This antibody does not recognize thymocytes, peripheral T cells, or nonlymphoid hematopoietic cells in the spleen or bone marrow. Nor does it recognize the pluripotent hematopoietic stem cells, the spleen colony-forming unit, All sIg+ B cells and most plasma cells are RA3-2C2+. In addition, approximate...

This paper presents a parameterized version of the stochastic information gradient (SIG) algorithm, in which the error distribution is modeled by generalized Gaussian density (GGD), with location, shape, and dispersion parameters. Compared with the kernel-based SIG (SIGKernel) algorithm, the GGD-based SIG (SIG-GGD) algorithm does not involve kernel width selection. If the error is zero-mean, th...

A topoframe, denoted by $L_{ tau}$, is a pair $(L, tau)$ consisting of a frame $L$ and a subframe $ tau $ all of whose elements are complementary elements in$L$. $f$-ring $mathcal{R}(L_{ tau})$ is equal to the set $${fin Frm(mathcal{P}(mathbb R), L): f(mathfrak{O}(mathbb R))subseteq tau} .$$ In this paper, for every complemented element $ain L$ with $a, a'...

We first characterize $tau$-complemented modules with relative (pre)-covers. We also introduce an extending module relative to $tau$-pure submodules on a hereditary torsion theory $tau$ and give its relationship with $tau$-complemented modules.

This study aims to determine the relationship between stress levels and online learning system for Muhammadiyah Bengkulu University Nursing Study Program students during COVID-19 pandemic. The research method was analyzed univariately by looking at frequency distribution bivariate analysis using Kendal tau-b correlation test. results showed a of 0.648 with strong direction positive value Sig.

With the increasing application requirements of spatial information, traditional spatial information techniques can not solve current application problems. As novel technologies that can implement sharing of enormous distributed resource, Grid and Web services provide an effective and efficient way to share and integrate spatial information on the web. Hence, an innovate framework, i.e. Spatial...
