Abstract In this research communication we describe the performance of dairy cow−calf pairs in two cow-driven CCC-systems differing cows' access to calves through computer-controlled gates (smart gates, SG). We investigated machine milk yield automatic milking system (AMS), calf growth, and intake supplemental concentrate. Two groups each with four cow-calf were housed a cow area, creep meeting...

Membrane fusion of a phospholipid vesicle with a planar lipid bilayer is preceded by an initial prefusion stage in which a region of the vesicle membrane adheres to the planar membrane. A resonance energy transfer (RET) imaging microscope, with measured spectral transfer functions and a pair of radiometrically calibrated video cameras, was used to determine both the area of the contact region a...

Separating audio sources from a convolutive mixture of signals from various independent sources is a very fascinating area in personal and professional context. The task of source separation becomes trickier when there is no idea about mixing environment and can be termed as blind audio source separation (BASS). Mixing scenario becomes more complicated when there is a difference between number ...

The aim of this study is separation of Fe2O3, TiO2 and V2O5 anomalies in Esfordi 1:100,000 sheet which is located in Bafq district, Central Iran. The analyzed elements of stream sediment samples taken in the area can be classified into 5 groups (factors) by factor analysis. The Concentration–Number (C-N) fractal model was used for delineation of the Fe2O3, TiO2 and V2O5 thresholds. According to...

We give the probability that two vectors in d-dimensional Euclidean space m,n ∈ R which are separated in R by an angle θ ∈ [0, π/2] have angular separation θR > π/2 following random projection into a k-dimensional subspace of R, k < d. This probability, which we call the ‘flip probability’, has several interesting properties: It is polynomial of order k in θ; it is independent of the original d...

An algebraic principle for blind source separation is presented in this paper. This separation principle identi"es a (smaller) set of equations whose solutions can blindly extract non-Gaussian signals. The concept of `Mth-order uncorrelatednessa is introduced and it is proven that for Mth-order uncorrelated source signals, signals with nonzero kth-order cumulant (2(k)M) can always be extracted ...

conclusions trichotillomania may also be seen in preschool-aged children and may be associated with separation anxiety disorder. improper and late treatment can be associated with a worsening of the disorder. case presentation a 4.5-year-old girl without any psychiatric disorders in the family. she was cared for by her mother, and the child had a history of separation anxiety. after detection o...

Proteomics studies rely on high-resolving separation techniques whereby the biological complexity can be unraveled. Both gel-based and liquid-phase separation principles are needed in order to mine deeper into the low abundant area of the proteins expressed in human cell samples. The expression levels that can be reached today with proteomics technology are still only reaching part of all prote...

A microfluidic system with a wide surface area per unit volume has the potential for use in highly efficient chemical synthesis, separation, and extraction. In the case of efficient water/oil separation and material extraction, it becomes important to form a stable two-layer laminar flow interface. Previously, we developed a silicon/glass microfluidic reactor, in which microchannel inner walls ...
