در این پژوهش پس از انتخاب مکان های نمونه برداری، ابتدا غنای گونه ای و شاخص تنوع عملکرد هر یک از ویژگی های گیاهی (قابلیت یا عدم قابلیت تثبیت ازت، شاخص سطح برگ (lai)، ارتفاع گیاه، وزن 1000 دانه، طول برگ، طول دوره گلدهی و شاخص های کیفیت علوفه) در 54 واحدهای نمونه برداری محاسبه شد و بر این اساس سه فرض؛ وجود رابطه نزدیک بین غنای گونه ای با زیتوده گیاهی، وجود رابطه نزدیک بین تنوع عملکرد میانگین وزنی ...

Center weighted median (CWM) filters, which have been recognized as detail preserving filters, are an important and the simplest subclass of weighted median (WM) filters. In this paper, we analyze the root signals of two-dimensional (2-D) CWM filters. In particular, we derive the required form for a signal to be a root of a 2-D CWM filter. The required form of signals to be roots is then used t...

RECENT INVESTIGATIONS HAVE SHOWN THAT TWO COMPONENTS OF COMMUNITY TRAIT COMPOSITION ARE IMPORTANT FOR KEY ECOSYSTEM PROCESSES: (i) the community-weighted mean trait value (CWM), related to the mass ratio hypothesis and dominant trait values in the community, and (ii) functional diversity (FD), related to the complementarity hypothesis and the divergence of trait values. However, no experiments ...

Chemical Workflow Manager (CWM) provides the non computer specialist a graphical user interface (GUI) to execute predefined chemistry related workflows. We provide several such predefined (and supported) workflows as products such as CWM Lead Finder and CWM Structure Comparer. CWM products are ready to use ‘one-click’ workflows. CWM is not a toolbox such as most of other workflow shells. Our vi...

AIMS To compare the discriminant validity of the DSM-IV and the ICD-10 classification of alcohol use disorders (AUD) with an alternative classification, the craving withdrawal model (CWM). CWM requires craving and withdrawal for the diagnosis of alcohol dependence and raises the alcohol abuse threshold to two DSM-IV AUD criteria. METHODS Data were derived from The Netherlands Mental Health Su...

Construction waste management (CWM) has received worldwide attention for some time. As a result, a plethora of research, investigating a wide array of CWM issues such as their profiles, practices, and performance, has been reported in individual economies around the globe. However, a cross-jurisdictional comparison of these issues is limitedly presented in the literature despite its importance ...

Cell wall modification (CWM) promotes the formation of aerenchyma in roots under waterlogging conditions as an adaptive mechanism. Lysigenous aerenchyma formation in roots improves oxygen transfer in plants, which highlights the importance of CWM as a focal point in waterlogging stress tolerance. We investigated the structural and functional compositions of CWM genes and their expression patter...

Conventional magnetic resonance imaging (MRI) allows investigators and clinicians to observe the anatomy and injuries of the cerebral white matter (CWM) in dogs. However, dynamic images based on the diffusion tensor (DT) technique are required to assess fiber tract integrity of the CWM. Diffusion tensor tractography (DTT) produces a three-dimensional representation in which data are displayed o...

The importance of accurate early diagnostics of autism that severely affects personal behavior and communication skills cannot be overstated. Neuropathological studies have revealed an abnormal anatomy of the cerebral white matter (CWM) in autistic brains. We explore a possibility of distinguishing between autistic and normal brains by a quantitative shape analysis of CWM gyrifications on 3D pr...
