Net primary productivity (NPP) is a key component of energy and matter transformation in the terrestrial ecosystem, and the responses of NPP to global change locally and regionally have been one of the most important aspects in climate–vegetation relationship studies. In order to isolate causal climatic factors, it is great meaningful to assess the response of seasonal variation of NPP to clima...

) Regression-based heteroskedasticity and serial correlation robust standard errors and specification tests are proposed for linear models that may not represent an expectation conditional on all past information. The statistics are computable via a sequence of linear regressions, and the procedures apply to models estimated by ordinary least squares or two stage least squares. Examples of the ...

introduction: direction and latency of electrical connectivity between different sites of brain explains brain neural functionality. we compared efficiency of cross correlation and phase locking methods in time lag estimation which are based on local field potential (lfp) and lfpspike signals, respectively. methods: signals recorded from mt area of a macaque’s brain was used in a simulation app...

Abstract:   Objectives: Flexion contractures of the proximal interphalangeal joint are of the most common complication result from surgical procedures and traumatic events.  Orthotic interventions for treatment of contractures may include serial splinting, serial casting, dynamic and/ or static progressive orthoses, or a combination of these orthoses.  This study aimed to determine the effect ...

Climate variability and change is threatening water resources around the world. One hundred and fourtheen (114) stations from Reference Hydrometric Basin Network (RHBN) around Canada with at least 30 years continuous data (up to 2011) were selected to study the trend in mean annual runoff for different periods of 30 to 100 years in step 10 years by non-parametric Mann-Kendall test. Effect of sh...

Observers often miss a second target (T2) if it follows an identified first target item (T1) within half a second in rapid serial visual presentation (RSVP), a finding termed the attentional blink. If two targets are presented in immediate succession, however, accuracy is excellent (Lag 1 sparing). The resource sharing hypothesis proposes a dynamic distribution of resources over a time span of ...
