26岁那年,joe Bonamassa发行了专辑Blues Deluxe,明年将迎来20周年的发行纪念,并且,它至今仍是joe最畅销的一张专辑。以下是joe的自述内容:这是一张翻唱歌曲的合辑,也包括了四首原创作品,其中便有“Woke Up Dreaming”这首歌,直至今日,我仍然在几乎每一场演出中演奏这首歌。我认为,重新审视我在那张专辑中使用的方法,然后去录制即将发行的Blues Deluxe,Vol.2专辑是件很酷的事。

We study a class of deep neural networks with architectures that form a directed acyclic graph(DAG).For backpropagation defined by gradient descent with adaptive momentum,we show weights converge for a large class of nonlinear activation functions.'The proof generalizes the results of Wu et al.(2008)who showed convergence for a feed-forward network with one hidden *** an example of the effectiveness of DAG architectures,we describe an example of compression through an AutoEncoder,and compare against sequential feed-forward networks under several metrics.

Objective: The United States faces a health care provider shortage yearly in many areas of the country, but most of all the rural areas are most impacted. The aim of this paper is 2-fold: To understand the factors that drive a medical student’s specialty choice through a systematic review article and how government initiatives consider what is important to students, to understand how other clinicians can help close the gap in primary care in the United States and what policies or barriers prevent them from doing so. Methods: This paper looks at nationally collected data, as well as meta-analysis reviews on the topic to help the reader better understand the issue of health care provider shortages. Conclusion: We must change the way we look at primary care and rural medicine. Rather than investing money in avenues that yield little return on investment, we as a nation should strategically fund and advance the scope of practice for rural medicine to make it attractive and competitive for clinicians to pursue. Being in a large deficit of clinical providers in general in our country, we must try to find new pathways to grow coverage in rural areas before our health care system is no longer equitable.

The ultraviolet-B （UV-B） portion of sunlight has received much atten- tion in the last three decades, because radiation from this spectral region increases due to the stratospheric ozone depletion, which results from increases of chlorofiuorocarbons in the atmosphere. Plant responses to UV-B exposure vary greatly and the interpretation of and comparison between studies is hindered, mainly by the contrasting experimental conditions used and interactive factors such as low light levels and possible artifacts due to the artificial experimental conditions. It seems likely that increases in solar UV-B radiation of the magnitude anticipated under current stratospheric ozone projections will not significantly inhibit photosynthesis and cause DNA damage in plants. This is in part due to the wellevolved protection mechanisms present in most plant species. One of the significant plant responses to UV-B is changes in foliar secondary chemistry, which could be translated into significant effects at higher trophic levels through plant-herbivore interactions and decomposition, Enhanced UV-B radiation due to stratospheric ozone depletion could also cause morphological changes that would affect competitive interactions, especially if contrasting UV-B sensitivity exists among the competitors,

In North America, disturbed riparian zones have had a deleterious effect on the life cycles of anadromous fish, especially the commercially and culturally important salmon and steelhead. The result has been a significant reduction in the numbers and average size of these fish. Tributaries of the John Day River are important spawning waters for western populations of these fish, and the National Forest Service and the Confederated Tribes of the Umatilla Indian Reservation are cooperating to restore floodplains and riparian zones in a number of these headwater tributaries. Herein we have conducted a pre-restoration study of macroinvertebrates and basic water quality parameters in one of these important spawning locations in central Oregon, Bull Run Creek. Results of the turbidity, pH, dissolved Oxygen, and temperature determinations indicate that overall water quality is good, and benthic macroinvertebrate sampling yielded a number of sensitive organisms, including members of Chloroperlidae, Peltoperlidae, Ryachophilidae, Odontoceridae, and Brachycentridae. At all sites, chironomid larvae (non-biting midge) dominated the assemblages. The EPT Index suggests that Bull Run Creek ranges from fair to excellent in terms of its ability to support sensitive species. Sorensen’s Similarity Coefficient indicates varying degrees of shared diversity between the sites, and Shannon’s entropy calculations suggest moderate to low species diversity at all sites, including the reference site on nearby Boundary Creek. Overall, this study indicates that Bull Run Creek is in fair condition and that it should benefit significantly from the restoration efforts.
