How and why to study mountains: topics and types of research between limits and opportunities by Laura Bonato

“… Field practice in a neighbouring ethnographic context – both culturally and geographically –, of which the researcher is a part, entails specific difficulties, epistemological and practical problems quite different from those faced by classical anthropology. Based on the experience gained in three different projects involving the western Alpine arc over the last decade, we intend to highlight the fact that in some contexts it is appropriate to prefer ‘peripheral’ anthropological research, less localised and based on shorter stays. …”

G-O vulnerability forecasting model and its improvement based on loss by Shi PENG, Hao GUO, Tao WANG

“…Each index to measure the vulnerability was analyzed.A mathematical definition of strong security was proposed,and the loss measurement and forecasting of vulnerability were used to solve the problem of software dependability uniform dimension.At the same time,loss occurrence law and the number of vulnerabilities found similarities between the law were discussed,to determine whether the use of software defect prediction model to predict the amount of loss.By referring to the classical G-O model,the predictive model of software loss was established,namely model was developed to predict the loss of G-O based vulnerabilities,and the accuracy of the model and the practicability of the test by using the actual data in the vulnerability database.…”

A brand new strategy of quantum relay strategy based on entanglement swapping by Min XU, Min NIE, Guang YANG, Changxing PEI

“…Quantum protocols based on entanglement are known as information security，reliability，flexibility and a broad prospect in use.Meanwhile，the fidelity of photons is also required.A new quantum relay strategy was proposed.By setting multi-relays between distant correspondents and under the assistance of classical communications，the strategy can execute entanglement swapping and entanglement purification to provide the correspondents with remote entanglement connection of stable fidelity.Performance analysis shows that by reasonable control of relay series，improvement of entanglement swapping and entanglement purification，the time delay and throughput can be significantly improved，necessary entanglement resources can be provided for the global quantum communication.…”

An approach of Bagging ensemble based on feature set and application for traffic classification by Yaguan QIAN, Xiaohui GUAN, Shuhui WU, Bensheng YUN, Dongxiao REN

“…Bagging is a classic ensemble approach,whose effectiveness depends on the diversity of component base classifiers.In order to gain the largest diversity,employing genetic algorithms to get independent feature subset for each base classifier was proposed.Meanwhile,for better generalization,the optimal weights for the base classifiers according to their predictive performance were selected.Finally,refined Bagging ensemble based on simple Softmax regression was applied successfully in traffic classification.The experiment result shows that the proposed approach can get more improvement than the original Bagging ensemble in classification performance,and is better than the random-forests to a certain extent.…”

A metapopulation model for sylvatic T. cruzi transmission with vector migration by Britnee Crawford, Christopher Kribs-Zaleta

“…This study presents a metapopulation model for the sylvatic transmission of Trypanosoma cruzi, the etiological agent of Chagas' disease, across multiple geographical regions and multiple overlapping host-vector transmission cycles.Classical qualitative analysis of the model and several submodels focuses on the parasite's basic reproductive number, illustrating how vector migration across patches and multiple transmission routes to hosts (including vertical transmission) determine the infection's persistence in each cycle.Numerical results focus on trends in endemic [equilibrium] persistence levels as functions of vector migration rates, and highlight the significance of the different epidemiological characteristics of transmission in each of the three regions.…”
