Antimicrobial drugs are fed to hogs at sub-therapeutic levels to prevent disease and promote growth. However, there is concern that the presence of antimicrobial drugs in hog feed is a factor promoting the development of antimicrobial drug-resistant bacteria. This study uses a sample-selection model to examine the impact that use has on the productivity of U.S. hog operations. The analysis did ...

The Histograms of Oriented Gradients (HOG) can produce good results in an image target recognition mission, but it requires the same size images for classification inputs. In response to this shortcoming, paper performs spatial pyramid segmentation on any size, gets pixel each block dynamically, and further calculates normalizes gradient oriented feature region layer. new is called Histogram Sp...

In this paper, we propose a method for human detection using co-occurrence of Histograms of Oriented Gradients (HOG) features and color features. This method expresses the co-occurrence between HOG and color features by Adaboost and generates the combination of the features effective for the identification automatically. Color features were calculated by making histograms that quantized hue and...

Content based image retrieval is the technique to retrieve similar images from a database that are visually similar to a given query image. It is an active and emerging research field in computer vision. In our proposed system, the Interest points based Histogram of Oriented Gradients (HOG) feature descriptor is used to retrieve the relevant images from the database. The dimensionality of the H...

I read with great interest Schmidt’s article on hog feces that was widely spread by Hurricane Floyd flooding in North Carolina (1). Should not all fecal matter, whether human, hog, poultry, or cattle, be held to the same standard of disposal? Why should municipalities be held to a higher level of waste purification for human fecal matter? Sheldon B. Cohen Psychiatrist (private practice) Atlanta...

In budding yeast, a signaling network known as the mitotic exit network (MEN) triggers exit from mitosis. We find that hypertonic stress allows MEN mutants to exit from mitosis in a manner dependent on the high osmolarity glycerol (HOG) mitogen-activated protein (MAP) kinase cascade. The HOG pathway drives exit from mitosis in MEN mutants by promoting the activation of the MEN effector, the pro...

Fuel for thought. A better measure of exposure to jet fuel shows that some military personnel may be at increased risk for adverse health effects from breathing noxious fumes. In this issue, Steve Wing, an associate professor of epidemiology in the School of Public Health at the University of North Carolina at Chapel Hill, and colleagues investigate environmental injustice in North Carolina's s...

A chemical fractionation procedure, previously found applicable to bovine thymus and bovine and ovine palatine tonsils, was used to fractionate rabbit and hog thymus. With respect to the chemical fractionation steps, yields of fractions, and optical and electrophoretic properties, extracts from hog and rabbit thymus were indistinguishable from similar extracts prepared from calf thymus. The stu...
