Toe clipping and ear clipping (also ear notching or ear punching) are frequently used methods for individual identification of laboratory rodents. These procedures potentially cause severe discomfort, which can reduce animal welfare and distort experimental results. However, no systematic summary of the evidence on this topic currently exists. We conducted a systematic review of the evidence fo...
Clipping (i.e., harvesting aboveground plant biomass) is common in agriculture and for bioenergy production. However, microbial responses to clipping in the context of climate warming are poorly understood. We investigated the interactive effects of grassland warming and clipping on soil properties and plant and microbial communities, in particular, on microbial functional genes. Clipping alone...
Background and Purpose: Tinea capitis and tinea unguium are regarded as global public health concerns. The purpose of the present study was to identify the etiological agents of tinea capitis and tinea unguium in patients, referring to the Central Laboratory of Yazd University of Medical Sciences, Yazd, Iran. Materials and Methods: This study was conducted during 2014-2015. Skin scraping, scal...
Keywords: Bé zier curve Curve intersection Bé zier clipping Hybrid clipping a b s t r a c t This paper presents a novel approach, called hybrid clipping, for computing all intersections between two polynomial Bé zier curves within a given parametric domain in the plane. Like Bé zier clipping, we compute a 'fat line' (a region along a line) to bound one of the curves. Then we compute a 'fat curv...
Inverse lighting is a technique for recovering the lighting environment of a scene from a single image of an object. Conventionally, inverse lighting assumes that a pixel value is proportional to radiance value, i.e. the response function of a camera is linear. Unfortunately, however, consumer cameras usually have unknown and nonlinear response functions, and therefore conventional inverse ligh...
− This paper presents the development of integrated near-end acoustic echo and noise reduction algorithm. The modified frequency-sampling filter (FSF) provides an effective filterbank for splitting signal into equally spaced frequency channels. The center clipper and attenuator are employed at each frequency bin for attenuating near-end acoustic echo and noise. The adaptive clipping threshold a...
Clipping is often observed in speech acquisition, due to the limited numerical range or the non-linear compensation of recording devices. The clipping inevitably changes the spectrum of speech signals, and thus partially distorts the speaker information contained in the signal. This paper investigates the impact of signal clipping on speaker recognition, and proposes a simple yet effective clip...
The CESR RF system consists of four 5-cell RF cavities 1. Each cell has a eld probe sensitive to the voltage in the cell. We used a single bunch circulating in the ring as the driving current which gives a w ell known spectrum. The signals from the eld probes were analyzed and we were able to identify the peaks seen in the spectra as higher-order modes HOMs that are excited by the beam in RF ca...
Information on the tiller development of hybrid bromegrass (Bromus inermis × Bromus riparius Rehm) is limited. The objective this study was to evaluate effect clipping frequency at vegetative and reproductive stages concentrations sugars ‘AC Knowles’ compared ‘Kirk’ crested wheatgrass (Agropyron cristatum L.). This experiment conducted in greenhouse using tillers vernalized plants dug from fiel...
in order to determine aqueous extract effects of cool-season turfgrass mixture clipping on germination and seedling growth of four weed species, laboratory and outdoor pot experiments were done at the experimental laboratory and greenhouse of the doroud parks and landscape organization, located in doroud, lorestan, iran. the first factor was the concentration of sport turfgrass clipping extract...
