Cultivated land fragmentation (CLF) is a key obstacle to agricultural development and has strong relationship with regional food security global sustainable development. However, few studies have analyzed the spatio-temporal distribution pattern evolution characteristics of CLF complex interactions among their influencing factors in rapidly developing regions. In this study, first, GlobeLand30 ...

Polycomb Repressive Complex (PRC) 2 catalyzes the H3K27me3 modification that warrants inheritance of a repressive chromatin structure during cell division, thereby assuring stable target gene repression in differentiated cells. It is still under investigation how H3K27me3 is passed on from maternal to filial strands during DNA replication; however, cell division can reinforce H3K27me3 coverage ...

Coupled cluster CCSD(T) calculations using the aug-cc-pVQZ basis set were performed on structures and energies of complexes O3-HF, O3-HCl, O3-OH, O3-H2, O3-N2, O3-CO, O3-O2, O3-F2, O3-Cl2, O3-ClF. Most have Cs symmetry, with symmetry plane being ozone (for hydrogen bonded O3-HF to O3-OH for halogen O3-Cl2 O3-ClF) or perpendicular most others). Dissociation De range from 718 1137 cm−1 O3-HCl com...

This paper considers MiniML equipped with a standard big-step semantics and a destination-passing semantics both represented in concurrent LF (CLF) and prove the two semantics equivalent. The proof is then examined yielding insights into the issues concerning induction on concurrent terms. We conclude by outlining some of the difficulties that one will need to address when designing a meta-logi...

Well-known web servers such as Apache and web proxies like Squid support event logging using a common log format. The logs produced using these de facto standard formats are invaluable to system administrators for troubleshooting a server and tool writers to craft tools that mine the log files and produce reports and trends. Furthermore, these log files can also be used to train anomaly detecti...

The problem of robust stabilization of nonlinear systems in the presence of input uncertainties is of great importance in practical implementation. Stabilizing control laws may not be robust to this type of uncertainty, especially if cancellation of nonlinearities is used in the design. By exploiting a connection between robustness and optimality, \domination redesign" of the control Lyapunov f...

CLF is a new logical framework with an intrinsic notion of concurrency. It is designed as a conservative extension of the linear logical framework LLF with the synchronous connectives ⊗, 1, !, and ∃ of intuitionistic linear logic, encapsulated in a monad. LLF is itself a conservative extension of LF with the asynchronous connectives −◦, & and >. In this report, the second of two technical repor...

Control Lyapunov function (CLF) is a successful attempt to directly use of the Lyapunov function stability analysis technique of nonlinear systems in the synthesis problem. In this paper, on the basis of Freeman’s work (1996), the concept of CLF are re-analyze through using the method of set-valued analysis. And then, a new CLF based nonlinear controller design framework, called generalized poi...

This article is concerned with practical stabilization of nonlinear systems by means inf-convolution-based sample-and-hold control. It a fairly general technique based on generic nonsmooth control Lyapunov function (CLF) and robust to actuator uncertainty, measurement noise, etc. The itself involves computation descent directions the CLF. turns out that nonexact realization this leads not just ...

We use the latest observations from the 2dF Galaxy Redshift Survey to fit the conditional luminosity function (CLF) formulation of the halo-model for galaxies at z = 0. This fit is then used to test the extent of evolution in the halo occupation distribution (HOD) to z = 0.8, by comparing the predicted clustering from this CLF to preliminary results from the DEEP2 Redshift Survey. We show that ...
