Wireless Sensor Networks (WSNs) are a pioneering technology in many environmental monitoring applications owing to their ability to be deployed for long periods of time in locations that cannot be reached manually. One such use-case is the monitoring of underwater sediment transport, a process that plays a significant role in coastal erosion. Previous examples of WSNs deployed for this purpose have been in the form of underwater sensor networks (UWSNs), which have a number of shortcomings from both a practical and technical viewpoint. As such, this paper provides a comparative assessment of UWSNs and an alternative deployment approach of floating echo- sounding sensor networks for the purpose of monitoring underwater sediment transport.

作者： ian j. DUNCAN

页岩气开采工业中水的用量，在文献中描述有的称为“惊人的”，而有的又称为“少量且短暂的”。相比于用来发电、灌溉用水量，页岩气开发中的用水只占到它们百分之几。

AIM: To model clinical and economic benef its of capsule endoscopy (CE) compared to ileo-colonoscopy and small bowel follow-through (SBFT) for evaluation of suspected Crohn’s disease (CD). METHODS: Using decision analytic modeling, total and yearly costs of diagnostic work-up for suspected CD were calculated, including procedure-related adverse events, hospitalizations, off ice visits, and medications. The model compared CE to SBFT following ileo-colonoscopy and secondarily compared CE to SBFT for initial evaluation. RESULTS: Aggregate charges for newly diagnosed, medically managed patients are approximately $8295. Patients requiring aggressive medical management costs are $29 508; requiring hospitalization, $49 074. At sensitivity > 98.7% and specifi city of > 86.4%, CE is less costly than SBFT. CONCLUSION: Costs of CE for diagnostic evaluationof suspected CD is comparable to SBFT and may be used immediately following ileo-colonoscopy.

For individuals with lower extremity inj.ry or disability, upper body exercise provides a mechanism of functional mobility training, car-diovascular fitness, as well as a means for clinical fitness assessment. However, the validity of fitness assessment relies on the efficacy of di-agnostic tools and measures in order to provide meaningful data to clinicians. The purpose of this investigation was to determine if the SciFitTMPro II Arm Ergometer, a widely available upper body ergometer (UBE), is a reliable device for the determination of VO2Peak in fit able-bodied swimmers. Eight trained male swimmers (28 ± 9 yrs) performed two incremental protocols VO2Peak consisting of a 4-min warm-up at 15 W followed by 2 min at 50 W and progressing 10 W every 2 min until volitional exhaustion. There was a linear relationship between workload and VO2 in all trials (R = 0.96;p ≤ 0.01) while Cronbach’s alpha for test-retest reliability for VO2 was 0.98. In conclusion, the UBE is an accurate and reliable device for determination of VO2Peak in trained swimmers, and further may be a viable alternative trainingVO2Peak inj.red athlete.

We discuss a possible interpretation of the open charm mesons D＊s0 （2317）,D s1 （2460） and the hidden charm mesons X（3872）,Y（3940） and Y（4140） as hadron *** a phenomenological Lagrangian approach we review the strong and radiative decays of the D＊ s0 （2317） and D s1 （2460） *** X（3872） is assumed to consist dominantly of molecular hadronic components with an additional small admixture of a charmonium *** the radiative （γj.ψ and γψ（2s）） and strong （j.ψ2π and j.ψ3π） decay modes we show that the present experimental observation is consistent with the molecular structure assumption of the X（3872）.Finally,we give evidence for molecular interpretations of the Y（3940） and Y（4140） related to the observed strong decay modes j.ψ＋ω or j.ψ＋φ,respectively.

近年来在非极端环境中已经发现有古菌(Archaea)的存在, 但在中国原始土壤中还未见报道。本研究的目的是调查古菌是否存在于两个分别取自中国新疆和广西的土壤及两个美国亚利桑那州南部地区的土壤中。我们分别构建了这四个原始土壤的古菌16S rDNA文库并对28个克隆的16S rDNA进行了鉴定。所有这些16S rDNA的序列都归类于古菌的泉古菌门(Crenarchaeota)。进化树分析表明, 这些泉古菌的16S rDNA属于非高温陆地环境中的泉古菌种群, 明显区别于海洋和淡水地带的泉古菌种群。这个泉古菌种群又有两个分支, 这两个分支在16S rDNA序列上和G+C含量上有明显的区别。本研究在两个中国和两个美国原始土壤中鉴定了非高温泉古菌的存在, 由此证明泉古菌的存在范围不只局限于高温等极端环境。另外, 美国原始土壤中的泉古菌只属于一个进化分支, 这说明非高温泉古菌种群的类型和土壤的地理位置及土壤特性有关。

Obj.ctive: We investigated rates of prostate cancer (PCa), high-grade prostatic intraepithelial neoplaisa (HGPIN) and atypical small acinar proliferation (ASAP) in a multiethnic cohort. Methods: We evaluated prostate biopsy outcomes in men enrolled in the San Antonio Center of Biomarkers of Risk for prostate cancer (SABOR) prospective, observational study. PCa-free men underwent annual PSA testing over nearly 14 years with biopsies based on community standards. We investigated biopsy outcomes with a special interest in rates of cancer, HGPIN, and ASAP. Results: We identified 975 prostate biopsies in 801 subj.cts from 3/1/2001 to 1/9/2014. PCa, HGPIN, or ASAP was encountered in 28.8% (281/975), 10.1% (98/975), and 5.2% (51/975) of prostate biopsy specimens, respectively. The most significant risk factor for a PCa diagnosis was African American race (OR 5.0, 95% CI: 2.2 - 11.4, p < 0.001). HGPIN and ASAP occurred more commonly in association with PCa (both p < 0.001). We identified 57% (24/42) of men diagnosed with a “pre-malignant” lesion on prostate biopsy and had a subsequent biopsy. Of those only 8% (2/24) were diagnosed with prostate cancer (both Gleason 3 + 3) within 1 year of the initial biopsy. Conclusion: We note a 5-fold increased risk of PCa for African American men. The incidence of HGPIN and ASAP are consistent with previously reported incidence. If diagnosed in isolation, repeat biopsy within one year could be delayed or eliminated as it may not change prostate cancer outcomes.

为了有效地保护生物多样性,需要有一个国际框架来保证国家的重点兼顾到地区的和全球的重点。国际鸟盟(BirdLifeInternational)已经发表了5份对世界鸟类的全球状况的全面评估以及2份欧洲大陆鸟类状况的评价。本文分析了这些评估结果针对欧洲56种猛禽和鸮类,这56个物种中18%具有全球保护意义,而64%在欧洲的保护状况不佳。欧盟(EU)拥有欧洲总的猛禽和鸮类繁育种群的一半,而俄罗斯欧洲部分拥有其余的1/3,但是每个欧洲国家都至少拥有两个具有欧洲保护意义的物种。20世纪90年代,大多数欧盟成员国的猛禽数量增加了而不是减少了,但是在东欧却恰好相反,许多最受威胁的物种减少了。根据公众对这些物种的熟知,以及到2010年停止生物多样性损失的政治承诺,我们需要进行更多的行动来监测和保护肉食鸟类。
