We investigate non-Abelian gauge theories within a Wilsonian Renormalisation Group approach. The cut-off term inherent in this approach leads to a modified Ward identity (mWI). It is shown that this mWI is compatible with the flow and that the full effective action satisfies the usual Ward identity (WI). The universal 1-loop β-function is derived within this approach and the extension to the 2-...

A set of permutations S on a finite linearly ordered set Ω is said to be k-min-wise independent, k-MWI for short, if Pr(minπ(X) = π(x)) = 1/|X | for every X ⊆Ω such that |X | ≤ k and for every x ∈ X . (Here π(x) and π(X) denote the image of the element x or subset X of Ω under the permutation π , and Pr refers to a probability distribution on S , which we take to be the uniform distribution.) W...

The GRACE follow-on satellites carry the very first interspacecraft Laser Ranging Interferometer (LRI). After more than four years in orbit, LRI outperforms sensitivity of conventional Microwave Instrument (MWI). However, current data processing scheme, product still needs MWI to determine unknown absolute laser frequency, representing “ruler” for converting raw phase measurements into a physic...

The bipolar resistive switching characteristics of resistive random access memory (ReRAM) based on HfO2 thin films have been demonstrated by using Ag/HfO2/Pt structured ReRAM device. MIcrowave irradiation (MWI) treatment at low temperature was employed in device fabrication with HfO2 thin films as a transition layer. Compared to the as-deposited Ag/HfO2/Pt device, highly improved uniformity cha...

In this work, an alternative attempt to motivate the Many-Worlds Interpretation (MWI) is undertaken. The usual way of arguing for MWI mostly revolves around how it might solve measurement problem in a more straightforward and concise manner than rival interpretations. However, here effort made defend indirect manner, namely via repeated case discrimination process ‘conceptual elimination’. That...

PURPOSE To assess the extent of demyelination in cervical spondylotic myelopathy (CSM) using myelin water imaging (MWI) and electrophysiologic techniques. METHODS Somatosensory evoked potentials (SSEPs) and MWI were acquired in 14 patients with CSM and 18 age-matched healthy controls. MWI was performed on a 3.0T whole body magnetic resonance scanner. Myelin water fraction (MWF) was extracted ...

Potent polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and dioxinlike polychlorinated biphenyls (PCBs) are among the most relevant toxic emissions from incinerators. Induction of cytochrome P450 1A1-catalyzed 7-ethoxyresorufin O-deethylase (EROD) activity in mammalian cell culture (EROD bioassay) is thought to be a selective and sensitive parameter used for the...

One of the primary conceptual difficulties facing the multiple worlds interpretation (MWI) of quantum mechanics is the interpretation of the Born rule measure as a probability. Given that each world in the MWI is typically envisioned as being equally “real,” a more natural rule would be to assign each of the N branches associated with a measurement the equivalent probability 1/N , rather than t...

Myelin water imaging (MWI) promises to be invaluable in understanding neurological diseases like MS. However, a limitation of MWI is signal to noise ratio. Recently, a number of investigators have performed MWI at field strengths higher than 1.5 T. Our goal was to determine if myelin water imaging at increased SNR, arising from the use of a small bore 7 T MR system with optimized coil geometry,...

The standard weighted L 2 norm total variation multiplicative regularization (MR) term originally developed for microwave imaging (MWI) algorithms is modified to take into account structural prior information, also known as spatial priors (SPs), about the object being imaged. This modification a...
