The prospect of combining both magnetic and plasmonic properties in a single nanoparticle promises both valuable insights on the properties of such systems from a fundamental viewpoint and numerous possibilities for technological applications. However, the combination of two of the most prominent metallic candidates—iron and silver—has presented numerous experimental difficulties because their thermodynamic properties impede miscibility and even coalescence. Herein, we present the thorough characterization of physically prepared Fe50Ag50 nanoparticles embedded in carbon and silica matrices via electron microscopy, optical spectroscopy, magnetometry and synchrotron-based X-ray spectroscopy. Iron and silver segregate completely into structures resembling fried eggs, with a nearly spherical, crystallized silver part surrounded by an amorphous structure of iron carbide or oxide, depending on the environment of the particles. Consequently, the particles exhibit both plasmonic absorption corresponding to the silver nanospheres in an oxide environment and a reduced but measurable magnetic response. The suitability of such nanoparticles for technological applications is discussed from the viewpoint of their high chemical reactivity with their environment.

作者： rafael Borge David de la Paz Julio Lumbreras Javier Pérez michel Vedrenne Laboratory of Environmental Modelling Technical University of Madrid (UPM) Spain

As environmental standards become more stringent (e.g. European Directive 2008/50/EC), more reliable and sophisticated modeling tools are needed to simulate measures and plans that may effectively tackle air quality exceedances, common in large cities across Europe, particularly for NO2. Modeling air quality in urban areas is rather complex since observed concentration values are a consequence of the interaction of multiple sources and processes that involve a wide range of spatial and temporal scales. Besides a consistent and robust multi-scale modeling system, comprehensive and flexible emission inventories are needed. This paper discusses the application of the WRF-SMOKE-CMAQ system to the Madrid city (Spain) to assess the contribution of the main emitting sectors in the region. A detailed emission inventory was compiled for this purpose. This inventory relies on bottom-up methods for the most important sources. It is coupled with the regional traffic model and it makes use of an extensive database of industrial, commercial and residential combustion plants. Less relevant sources are downscaled from national or regional inventories. This paper reports the methodology and main results of the source apportionment study performed to understand the origin of pollution (main sectors and geographical areas) and define clear targets for the abatement strategy. Finally the structure of the air quality monitoring is analyzed and discussed to identify options to improve the monitoring strategy not only in the Madrid city but the whole metropolitan area.

dear Editor, Potyviruses such as Papaya ring-spot virus （PRSV） cause important yield losses in cucurbits. Two distinct resistant alleles were identified in the Cucumis melo germplasm. Accession PI 414723 （Supplemental Table 1） possesses mono- genic resistance, controlled by the Prv2 allele, and reacts to PRSV by systemic necrotic lesions; plants with the PryI allele, described in cultivar WMR-29, remain symptomless （Pitrat and Lecoq, 1983）. Fusarium oxysporum f. sp. melonis （FUS） exclusively attacks melon, causing severe wilt. Monogenic dominant resistance was described against races O, 1, and 2. The Fore-2 gene, controlling resistance to races 0 and 1, was cloned by Joobeur et al. （2004）, and encodes a nucleotide bindina domain （NB）-Ieucine rich repeat （LRR） protein.

Acapulco, Mexico has a coastline of 62 km where large areas of rocky substrate inhabited by organisms such as the GASTROPODA Class can be found. Conidae (Fleming, 1822) Family is among the members of this Class, which has been poorly studied in the Mexican Pacific, despite their biomedical potential. This research was carried out in the rocky intertidal of nine sites in Acapulco. The objectives were: 1) Prepare an inventory of species associated with rocky intertidal of Conidae family, 2) examine the composition of the family based on two criteria: a) species richness and b) abundance, 3) determine the geographical distribution and 4) analyze the size composition. The unit sampled was 1 m2 and the sampled area was 10 m2 persite. A total of 97 organisms were analyzed, corresponding to two subfamilies, five genera and five species. The Puncticuliinae (Tucker & Tenorio, 2009) subfamily had higher species richness, abundance and frequency of occurrence. The most abundant and most common species were Harmoniconus nux (Broderip, 1833) and Gladioconus gladiator (Broderip, 1833) both showed regular distribution. The size structure found for Conidae family is similar to what has been reported in other research. For the first time G. gladiator is being reported for the state of Guerrero.

The GASTROPODA class, one of the best known marine environments, is formed by a large number of species and the shape of their shell structure varies greatly. These mollusks are distributed from the intertidal zone all the way to the abyssal zone, and there are also swimming and floating species. This research was conducted at seven sites, located in the Marina Priority Region 32 (MPR 32), located in the State of Guerrero, Mexico. The aim of this report is to document the scope of the geographic distribution of the 34 species of GASTROPODA class. 11,263 total specimens were analyzed. 108 species were identified, of which four species are new records for Mexico, 15 for the Transitional Mexican Pacific, 11 for the State of Guerrero and four for the MPR 32. Here we report a significant number of new records of species of class GASTROPODA found on the rocky intertidal zone of the MPR 32. The reporting of these new records, demonstrates the need to focus research efforts on the study of marine diversity, since knowledge in this respect is quite incomplete, especially regarding marine mollusks, a fact that has been reported by the National Commission for the Management and Use of Biodiversity.

Objectives/Hypothesis: The introduction of intranasal pedicled flaps has reduced the incidence of postoperative cerebrospinal fluid (CSF) leaks to less than 5%. Nevertheless, in malignant tumors those flaps are not always available because of nasal septum invasion. Minimally invasive pericranial flaps (PCF) are associated with minimal adverse effects and good cosmetic appearance. In spite of that, there are only a few reports of this reconstructive technic limited to short surgical series and radio-anatomical analysis. Clinical results of a surgical cohort are presented. Study design: Cohort prospective study. Methods: Clinical data, including age, gender, stage, histopathological findings, rate of complications and appearance of PCF at fifth day and two months postoperative were recorded. Postoperative morbidities were recorded as wound abnormalities, nasosinusal, orbital and central nervous system complications. Chi-squared test was used to correlate qualitative variables and Student-t-test to correlated qualitative and quantitative variables. Items were considered statistically significant with a p value of less than 0.05 (confidence Interval of 95%). Results: Thirty patients (18 males and 12 females) were registered. Mean age was 51.5 years ± 23.0 and range between 20 and 71 years. Most common histologic subtypes were adenocarcinoma, epidermoid carcinoma and squamous cell carcinoma. Complete resection of the tumor was achieved in all patients including surgical margins. Length of the PCF varies between 9.9 cm and 13.9 cm with a mean of 11.8 cm. There was an association between length of the flaps and the covering structure with the nose apex relation. None patient experienced postoperative cerebrospinal fluid (CSF) leak, frontal sinusitis or other complications. Conclusions: Minimally invasive PCF constitute a good and inexpensive reconstructive option in patients with malignant anterior cranial base tumors in whose nasoseptal flap was not a feasible option.

信息伦理学的本体论基础

文章首先对信息伦理学的悠久历史作了简单回顾。信息伦理学起源于米歇尔·佛科特(michel FoucauIt)所分析的希腊语概念“自由演说”或言论自由。关于信息伦理学的最新概念尤其与20世纪随着计算机技术和因特网的发展而出现的各种问题密切相关,它包括大众媒体、图书馆学、信息科学以及商业等领域的伦理问题。从广义上说,信息伦理学概念涉及所有可能现象的数字重建,从而导致与数字本体论相关的种种问题。作者根据海德格尔关于本体论与形而上学关系的观点,认为本体论与“存在”本身有关,它不仅仅与形而上学讨论的主题即生物的生存有关。本文将海德格尔的理论和乔治·斯宾赛·布朗(George Spencer Brown)、高特路·甫瑞(Gottlob Frege)、尼克拉斯·鲁曼(Niklas Luhmann)等学者的学说相提并论,同时加以比较。用佛科特的专业术语来说,本体论是形而上学的尴尬困境。从本体论的角度探讨信息伦理学的基础,其首要目的是质疑数字本体论的形而上学的奢望。数字本体论被认为是当今对“存在”的普遍理解。作者把人类存在作为一种与万物存在即“无标记空间”相关的伦理关系加以分析,在此基础上探讨一些数字技术的挑战,并着重分析数字代理人的道德状况。作者据理论证,信息伦理学不仅仅涉及与佛劳瑞德(Floridi)所提到的“信息领域”相关的伦理问题。文章将这种观点与佛劳瑞德提出的关于信息伦理学基础以及数码代理人道德状态的论点进行对比分析。文章认为,简化论者把人体作为数字数据的观点忽视了数字本体论的局限性,抛弃了伦理定位的基础。最后,文章探讨了同“数字分隔”相关的问题以及信息伦理学跨文化的方方面面,并提出了长期和短期的研究设想。
