This paper focuses on the use of models for increasing the precision of estimators in large-area forest surveys. It is motivated by the increasing availability of remotely sensed data, which facilitates the development of models predicting the variables of interest in forest surveys. We present, review and compare three different estimation frameworks where models play a core role： model-assisted, model-based, and hybrid estimation. The first two are well known, whereas the third has only recently been introduced in forest surveys. Hybrid inference mixes design- based and model-based inference, since it relies on a probability sample of auxiliary data and a model predicting the target variable from the auxiliary *** review studies on large-area forest surveys based on model-assisted, model- based, and hybrid estimation, and discuss advantages and disadvantages of the approaches. We conclude that no general recommendations can be made about whether model-assisted, model-based, or hybrid estimation should be preferred. The choice depends on the objective of the survey and the possibilities to acquire appropriate field and remotely sensed data. We also conclude that modelling approaches can only be successfully applied for estimating target variables such as growing stock volume or biomass, which are adequately related to commonly available remotely sensed data, and thus purely field based surveys remain important for several important forest parameters.

American Journal of Analytical Chemistry 2013年第1期4卷 44-50页

Tembotrione is herbicide which belongs to the triketone group of herbicides. It’s registered as a selective, post-emergence herbicide developed for the control of a broad spectrum broadleaf and grassy weeds in corn. There is little information about tembotrione because of his short presence in the market. Due to its ever wider application, it is important to know the details of its chemical characteristics and redox processes, including biogeochemical transformation and migration after application to agricultural land, which could contribute to its efficient and safer application. In this paper we examined voltammetric behavior of tembotrione using Silver/Amalgam (Ag/Hg) electrode. For the investigation of electrochemical behavior we used the cyclic voltammetry technique, with conventional three-electrode cell and electrochemical workstation. During the experiment pH values of solution varieties while constant concentration of tembotrione was maintained. Cyclic voltammograms were recorded at pH values 6, 8, 10 and 12, at which tembotrione was electrochemically active. At this pH values two signals were observed. Optimum pH value, at which the current intensity was greatest, was 12. Obtained results provide relevant information on the electrochemical behavior of tembotrione, which can serve as a basis for the development of electrochemical techniques for the removal and degradation of this pesticide in the environment.

In this paper, we coupled the Quantum Mechanics conventional Schrödinger’s equation, for the particles, with the Maxwell’s wave equation, in order to study the potential’s role on the conversion of the electromagnetic field energy to mass and vice versa. We show that the dissipation (“conductivity”) factor and the particle implicit proper frequency are both related to the potential energy. We have also derived a new expression for the Schrödinger’s Equation considering the potential energy into this equation not as an ad hoc term, but also as an operator (Hermitian), which has the scalar potential energy as a natural eigenvalue of this operator.

Bone blood flow is influenced by muscle contractions

Journal of Biomedical Science and Engineering 2011年第7期4卷 490-496页

Forces acting on the skeleton could be divided into those originating from gravitational loading and those originating from muscle loading. Flat bones in a non-weight-baring segment of the skeleton probably experience forces mostly generated by muscle contractions. One purpose of muscle contractions is to generate blood flow within skeletal tissues. The present study aimed to investigate the pulsatile patellar bone blood flow after low and high intensity leg extension exercises. Forty-two healthy individuals volunteered for the study. Dynamic isotonic one leg extension/flexion exercises were performed in a leg extension machine. Randomly, the exercises were performed with the left or right leg with either 10 repetition maximum (10 RM) continuously without any resting periods (high intensity muscle work), or 20 RM with a 2 second rest between contractions (low intensity muscle work). The work load, expressed in kilograms totally lifted, was identical in both legs. The pulsatile patellar blood flow was recorded continuously using a photoplethysmographic technique. Blood pressure was measured continuously during muscle work by a non-invasive method (Finapress). The patellar pulsatile bone blood flow increased significantly more after high intensity muscle work (61%) compared to the same work load performed using a lower intensity (22%), p = 0.000073. Systolic blood pressure changed equally during and after both interventions. Post-exercise bone hyperaemia appears to be correlated to the intensity of muscle contractions in the muscle compartment attached to the bone.

＜正＞ Urban bridges very often become benchmarks of the city or metropolis, specially if they present aesthetical achievement. This fact has to be accepted during the design process. Therefore the shape or details of some urban bridge very often try to present some part of cities history, some technologies that characterize some city era or are simply dedicated to one time period of the city development. The paper shows examples of old bridges constructed centuries ago in the old stone city of Dubrovnik, one of the best preserved centers of Mediterranean mediaeval architecture. In the vicinity of old bridges, a new cable-stayed urban bridge has been completed in the 2002, with the main span of 303 meters. During the phases of conceptual, preliminary and final design special attention has been payed to interaction between historical background and new technologies and materials that had to be applied on a new structure.

In this paper experimental data about the creep behavior of high strength low-alloy （HSLA, ASTM A618） steel are presented. For different elevated temperatures （Ti） tensile tests （σ?ε） are carried out and also for some of the mentioned elevated temperatures one-dimensional creep tests （ε-t） for different constant loads （Fi） are made. Experiments are carried out using computer controlled 400 kN materials testing machine equipped by a high temperature furnace and a corresponding high temperature extensometer. These experiments belong to the testing material mechanical properties and viscoplastic responses of the material under consideration. The obtained results of material properties and creep behavior are necessary for determining e.g. the load-carrying capacity of a structure under fire conditions as well as for its lifetime prediction..

Engineering（科研） 2021年第1期13卷 30-44页

作者： Raogo Kabore Adlès Kouassi Rodrigue N’goran Olivier Asseu Yvon Kermarrec Philippe Lenca Lastic ESATIC Abidjan C&#244 te d’Ivoire Lab-STICC IMT-Atlantique Brest France

Industrial Control Systems (ICS) or SCADA networks are increasingly targeted by cyber-attacks as their architectures shifted from proprietary hardware, software and protocols to standard and open sources ones. Furthermore, these systems which used to be isolated are now interconnected to corporate networks and to the Internet. Among the countermeasures to mitigate the threats, anomaly detection systems play an important role as they can help detect even unknown attacks. Deep learning which has gained a great attention in the last few years due to excellent results in image, video and natural language processing is being used for anomaly detection in information security, particularly in SCADA networks. The salient features of the data from SCADA networks are learnt as hierarchical representation using deep architectures, and those learnt features are used to classify the data into normal or anomalous ones. This article is a review of various architectures such as Convolutional Neural Network (CNN), Recurrent Neural Network (RNN), Stacked Autoencoder (SAE), Long Short Term Memory (LSTM), or a combination of those architectures, for anomaly detection purpose in SCADA networks.

AIM To compare gut bacterial diversity and amount of Enterobacteriaceae in colonic mucosa between patients with and without diverticular disease(DD).METHODS Patients in a stable clinical condition with planned elective colonoscopy were included. Blood samples and colon mucosa biopsies were collected at the colonoscopy. Study questionnaires including questions about gastrointestinal symptoms were completed by the patients and physicians. DNA from mucosa samples was isolated and the amount of Enterobacteriaceae was estimated using PCR assay. Terminal restriction frag mentlength polymorphism was applied to assess microbial diversity. Diversity was estimated by calculations of richness(number of terminal restriction fragments) and Shannon-Wiener and Simpson's indices. RESULTS A total of 51 patients were included, 16 patients with DD [68(62-76) years] and 35 controls [62(40-74) years] without any diverticula. Patients with DD had significantly higher levels of Enterobacteriaceae than those without DD(P = 0.043), and there was an inverse relationship between the amount of Enterobacteriaceae and the Simpson's index(rs =-0.361, P = 0.033) and the Shannon-Wiener index(rs =-0.299, P = 0.081). The Simpson's index(P = 0.383), Shannon-Wiener index(P = 0.401) or number of restrictions fragments(P = 0.776) did not differ between DD and controls. The majority of patients experienced gastrointestinal symptoms, and 22 patients(43.1%) fulfilled the criteria for irritable bowel syndrome, with no difference between the groups(P = 0.212). Demography, socioeconomic status, lifestyle habits, inflammatory biomarkers, or symptoms were not related to the amount of Enterobacteriaceae or bacterial diversity. CONCLUSION Patients with DD had higher amount of Enterobacteriaceae in the colon mucosa compared to patients without diverticula.
