The spatial distribution of current and temperature plays important role in the electrochemical performance of Solid Oxide Electrolysis Cells (SOECs). Many numerical predictions of current and temperature distribution have been reported, whereas experimental investigations were rare. In this research, we are applying a electrode-segmentation [1] method to investigate the spatial current and temperature variation in a cathode-supported microtubular SOEC. The electrode-segmentation method shows a remarkable current variation among the segments. The current densities of the midstream and downstream segments are smaller than the upstream segment with an increased cell voltage, implying that the cell suffers from water starvation. Besides, the temperature at each segment increases with the voltage increase. The largest current in the upstream segment is observed, which agrees with the largest temperature rise there. The largest temperature gradient happens between the upstream and midstream segments. References Aydin, T. Koshiyama, H. Nakajima, T. Kitahara, Journal of Power Sources, 279, 218-223 (2015).

The deep sea port development as an economic infrastructure influences positively on the growth of a country. The economic history of Britain, Netherlands, and Singapore, known as the maritime powers in the world, undoubtedly proves the important role of ports played in the development of their economies.

This study, therefore, has focused on the importance of deep seaport in the national development of Bangladesh. Moreover, the paper gives an overview of a deep seaport and national development in respect of Bangladesh.The study also indicates the effect of a deep seaport on national development. At the end, this study states some recommendations for the establishment of the deep sea port.Those Includes-Studies on the selection of strategic location, details investigation of hinterland connectivity, the decision on investment and proper planning etc.

Port and supply chains are closely connected to each other as a port is considered as an important node of the global supply chain. Sothe efficiency level of port has an impact on the performance of supply chain operations. Chittagong port is the principal seaport of Bangladesh and it provides a major gateway to the outside world. The cost of doing business is increasing as a result of the inefficiency in the main seaport of the country. In this paper, an effort has been taken to examine the efficiency of Chittagong Port and the causal factors of inefficiency. The impact of inefficiency at Chittagong port on the supply chain of Bangladesh has also been identified. To do this, at first a relationship has been built between port efficiency and supply chain in respect of Bangladesh. Relevant data has been gathered through extensive review of the literature, field surveys, interacting with top management of different business entities such as shipping agency, freight forwarder, logistics companies, exporter, importer as well as Government regulatory and monitoring bodies using both the structured and unstructured questionnaires. The study has revealed that theinefficiency at Chittagong port causes serious consequences on the supply chain of exporter and importer and lead to loss and disruption of trade and ultimately incur extra costs and time. This paper, therefore, recommends a substantial infrastructure improvement to Chittagong port along with other related measures in order to facilitate the supply chain of exporter and importer.

Background Lung ultrasound (LUS) is widely used to diagnose neonatal respiratory diseases. However, to our knowledge, few straightforward method was reported to predict respiratory support need precisely. Our aim is to determine the diagnostic accuracy of a semiquantitative LUS assessent method predicting the need for respiratory support. Methods We conducted a prospective diagnostic accuracy study following STARD (Standards for the Reporting of Diagnostic Accuracy Studies) guidelines at a tertiary level academic hospital between 2019 to 2020. 310 late preterm and term infants enrolled. They were delivered in the obstetric department and transferred to a monitoring room to determine whether they need NICU treatment. The LUS assessment was performed for each participant at one of following timings–0.5h, 1h, 2h, 4h, 6h after birth. Reliability was tested by ROC analysis. Surfactant administration and other respiratory support were based on 2019 European guidelines as well as their clinical condition. Results 74 were confirmed to need respiratory support and 236 were healthy according to a 3-day follow up. Six LUS image patterns can be seen in these infants right after birth. Two “high-risk” patterns well relate to respiratory support need(area under the curve(AUC) = 0.95; 95% CI, 0.92-0.98, p

The model testing method in software testing theory can effectively reduce the uncertainty in testing, increase the effectiveness of test sequence generation, and lay the foundation of automated testing process. The Extended Finite State Machine (EFSM), being a tool that can precisely describe the dynamic process of a software or protocol et.al, has been widely studied in the field of software testing. Different from the traditional Finite State Machine (FSM), EFSM additionally introduced data flow process on the basis of the original control flow, which however limits ability to generate Feasible Transition Paths (FTP). As a kind of heuristic algorithm, Genetic Algorithm (GA) is able to take control flow and data flow simultaneously into account to ensure the efficiency of test sequence and test case generation process. Being first to apply GA to TTE, this paper selects the compression master (CM) protocol state machine from the Time-Triggered Ethernet (TTE) clock synchronization protocol, and uses a genetic algorithm to generate executable test paths for the state machine, tending to find a new way to study the test case generation of TTE. In the process, a single-objective optimization method will be used, and at the end of the essay, a comparation of a GA-generated test path between a randomly generated test path will be proceed to conclude that it is an efficient way.

Background Lungultarsound(LUS) is widely used to diagnose neonatal lung diseases, yet image patterns on intrauterine to extrauterine stage(right after birth), of which impairment is well related to lung disease, remains unclear. Objectives To identify these image patterns that can distinguish healthy infants from infants with lung disease.Methods This is a nested case-control study in a top-ranking obstetrics hospital in China, between 1 January 2020 to 1 April 2020. Infants transferred to the NICU after birth who had LUS obtained at 0.5, 1, 2, 4, 6 hours time intervals were enrolled. Confirmed by 3-day follow-up, case and control groups contains 22 patients and 473 healthy infants. Their GA ranges from 33.5 to 41.0 weeks. A newly designed protocol was used to capture the LUS image. The image patterns and their variations were shown and categorized as high and low-risk groups. The predictive value for healthy infants and patients were calculated. Results Low-risk patterns, accompanied with no high-risk ones, typically appeared in healthy infants (specificity=86.4%, PPV=99.0%), whereas four high-risk patterns could be seen in both healthy infants and patients (specificity=62.4%, PPV=9.6%). High-risk patterns were more likely to be pathological signs when appearing at the oxter and lower back and to be physiological signs when appearing at the prothorax. Conclusions LUS is valid to differentiate healthy infants from potential patients shortly after birth. Infants with low-risk patterns only are highly likely to be healthy, whereas infants with high-risk patterns have a risk for respiratory issues but need prolonged monitoring to confirm.

Purpose To distinguish healthy infants from potential patients right after birth using lungultrasound(LUS). Design, Setting and Patients This is a nested case-control study containing 22 lung diseases patients and 473 healthy infants from a total of 504 successive infants. They were admitted to Obstetrics & Gynecology Hospital of Fudan University, Shanghai, China, from 1st January 2020 to 1st April 2020. A newly designed scanning protocol was used to capture LUS images. Sensitivity, specificity, PPV and NPV for predicting healthy infants and patients were calculated individually. The transition process image patterns and thier variation were shown. The relationship between clinic signs and the high-risk image patterns was calculated by Kendall’s tau-b test. Measurements and main results LUS images were captured and its preditive value has been caculated. Four low-risk patterns almost only can be seen in healthy infants(specificity=86.4%, PPV=99.0%) whereas four high-risk patterns can be seen both in healthy infants and patients(specificity=62.4%, PPV=9.6%). High-risk patterns are more likely to be pathological when appearing at oxter and lower back but to be a physiological sign when appearing at Lower and upper of the prothorax. These high-risk patterns are significantly related to clinic sign. All these patterns are alsmost consistent during 6 hours after birth. Conclusions LUS is valid to differentiate healthy infants from potential patients who with mild respiratory difficulty. Four low-risk patterns have high value to predict healthy infants, but four high-risk patterns are not specific enough to discover patients. This criterion is valid for this 6 hours stage.

The outbreak of the novel coronavirus disease (COVID‐19) quickly spread all over China and to more than 20 other countries. Although the virus (severe acute respiratory syndrome coronavirus [SARS‐Cov‐2]) nucleic acid real‐time polymerase chain reaction (PCR) test has become the standard method for diagnosis of SARS‐CoV‐2 infection, these real‐time PCR test kits have many limitations. In addition, high false‐negative rates were reported. There is an urgent need for an accurate and rapid test method to quickly identify a large number of infected patients and asymptomatic carriers to prevent virus transmission and assure timely treatment of patients. We have developed a rapid and simple point‐of‐care lateral flow immunoassay that can detect immunoglobulin M (IgM) and IgG antibodies simultaneously against SARS‐CoV‐2 virus in human blood within 15 minutes which can detect patients at different infection stages. With this test kit, we carried out clinical studies to validate its clinical efficacy uses. The clinical detection sensitivity and specificity of this test were measured using blood samples collected from 397 PCR confirmed COVID‐19 patients and 128 negative patients at eight different clinical sites. The overall testing sensitivity was 88.66% and specificity was 90.63%. In addition, we evaluated clinical diagnosis results obtained from different types of venous and fingerstick blood samples. The results indicated great detection consistency among samples from fingerstick blood, serum and plasma of venous blood. The IgM‐IgG combined assay has better utility and sensitivity compared with a single IgM or IgG test. It can be used for the rapid screening of SARS‐CoV‐2 carriers, symptomatic or asymptomatic, in hospitals, clinics, and test laboratories.

Laser-induced breakdown spectroscopy (LIBS) has been considered a promising technology for nuclear safeguard inspection, especially for isotope content ratio determination, since it can be easily designed for portable, fast, and in situ measurement. However, it was a challenge to determine hydrogen isotopes in metal samples due to the unfavorable spectral interference, the poor calibration of the hydrogen content, and the small difference between the atomic emission intensity of hydrogen isotopes at around 656.28 nm. This paper presents the determination of hydrogen isotope contents ratio using LIBS under partially baseline-resolved conditions. The results show that by introducing a proper buffer atmosphere for the LIBS measurement, the resolution of the hydrogen and deuterium emissions could be improved, but still not enabled, by a baseline resolution with a moderate resolution spectrometer. However, with the method of integral intensity correction, the accurate quantitative measurement of hydrogen and deuterium contents in a metal matrix could be achieved. This work provided the possibilities for the further development of LIBS in hydrogen isotopes in in situ measurement for nuclear safeguards.

We propose and demonstrate a 0.5 mm resolution distributed fiber temperature and strain sensor with position-deviation compensation based on the Optical Frequency Domain Reflectometry. The position-deviation compensation helps maintain the cross-correlation of the Rayleigh spectra, which degenerates at the higher resolution. Experimental results reveal a 0.5 mm strained fiber segment recognized at the end of a 25 m fiber, with 50,000 equivalent measuring points. The temperature repeatability of ± 0.9 °C (12.5 pm) is obtained from 50 °C to 500 °C with an 18 m gold-coated fiber, and the strain accuracy of ± 15 µɛ is also achieved within ± 2500 µɛ using a polyimide coated fiber. The small-scale, high spatial-resolution, and electromagnetic-immune distributed optical fiber sensors can be applied to address the test challenges in astronautics, advanced materials, and nuclear facilities, where high temperature, large strain change, space radiation, and complex electromagnetics presents.

Childhood community-acquired pneumonia (CAP) is a common illness; however, comprehensive studies of hospitalizations for CAP among children in China based on prospective and multicenter data collection are limited. The aim of this investigation was to determine the respiratory pathogens responsible for CAP in hospitalized children. From January to December 2015, oropharyngeal swabs and blood serum were collected from hospitalized children with CAP symptoms ranging in age from 6 months to 14 years at 10 hospitals across China. We used immunofluorescence to detect antibodies for eight respiratory viruses and passive agglutination to detect specific IgM against Mycoplasma pneumoniae (M. pneumoniae). Of 1500 children presenting with CAP, 691 (46.1%) tested positive for at least one pathogen (virus or M. pneumoniae). M. pneumoniae (32.4%) was detected most frequently, followed by respiratory syncytial virus (11.5%), adenovirus (5.0%), influenza A virus (4.1 %), influenza B virus (3.4%), parainfluenza virus types 2 and 3 type (3.1 %), parainfluenza virus type 1 (2.9%), and human metapneumovirus (0.3%). Co-infections were identified in 128 (18.5%) of the 691 cases. These data provide a better understanding of viral etiology and M. pneumoniae in CAP in children between 6 months and 14 years in China. More study of the etiologic investigations that would further aid the management of pneumonia is required. With effective immunization for RSV, ADV, and M. pneumoniae infections, more than one-half of the pneumonia cases in this study could have been prevented.

With the rising trends in interconnectivity, ensuring cyber security is of paramount importance. Cyber security experimentation platform can help researchers simulate real-world cyber topologies, analyze various attacks and experiment defense strategies. While traditional platforms does not scale well with the evolving cyber topologies and does not have much flexibility in-terms of functionalities. This paper presents a new architecture for experimentation platform of cyber security, based on Docker. It possesses the scalability factor necessary for large cyber simulations and also provides a flexible extension mechanism. This feature enables users to customize cyber node's topologies, software environment, and also support the customization of important experiment indicators. Kubernetes enables virtual nodes to be deployed on distributed servers readily, and the important experiment indicators can be relayed back in real-time which reduces the overall cost and helps speedup the experimental analysis.

We propose an experimental adsorption device, imitating the environment of a coal-mine goaf and the composition of the flue gas in Tashan Mine Power Plant. The characteristics of the coal adsorbing flue gas were studied with the atmospheric volumetric method. The factors affecting the seal of CO2 were analyzed and the effect of power plant flue gas on fire prevention in the goaf was investigated at normal temperature and pressure. It can be inferred from the experiment that N2, SO2, and H2O can also reduce CO2 adsorption capacity. The increase or decrease in pH can increase the adsorption capacity of CO2, which is apparently larger when the pH is decreasing than when the pH is increasing. The O2 adsorption capacity can evidently be reduced when the power plant flue gas is injected into the goaf. The activation energy of coal burned in air is greater than that of coal burned in flue gas, indicating that the use of power plant flue gas, with N2 and CO2 as the main components, to replace the traditional inert gas can not only save N2 generation cost, but also reduce the emission of greenhouse gases, while the power plant flue gas can be adsorbed by coal.

The need for an intelligent controller which is universally compatible to both pole-mounted circuit breakers and switch disconnectors with different automatic controlling logics in fault isolation has been promoted in recent years. A novel design of universal intelligent pole-mounted switch controller is introduced in this paper. Hardware scheme of the design is presented in detail. The hardware circuit is controlled surrounding i.MX6UL, and the design idea of man-machine interface, communication and power supply module are presented. Data acquisition is completed by using AD7606. Through the design of the hardware platform, a debugging and working basis for the software platform is provided.

Energy saving and emission reduction has been the core of the development of the global economy, the focus of people's attention, based on the CAN bus intelligent temperature control system can save building energy consumption, thereby reducing amount of coal, reducing emissions of pollutants. The data of intelligent control system can use two modes, master-slave mode or take the initiative to upload. Through the experiment and analysis, the conclusion is that the time of room temperature decreased one degree is about 40 minutes, when master-slave mode was used, data processing time is not more than 1s, and the master node can according to need to set the idle time, greatly reducing the frequency of data processing, and not timely processing of the data caused economic losses rarely, when active the uploading mode was used, due to mutual interference upload interval is uncertain. Therefore, the energy-efficient heating system of construction using master-slave mode is better.

Energy-saving and pollution reduction is of great social significance. In this system CAN-bus technology is used for its characteristics of flexibility, reliability, real-time, longer transmission distance than that of the 485 bus. Module K7110 is used to convert RS232 and CAN data connected to the CAN-bus. Thermocouple input module K8510 connected with a temperature sensor are used to collect temperature data. Relay output module K8518 and electric valve which is installed on every inlet pipe of radiator are used to control the heat flow according to the commands from the system. The software can accept user's setting for room mode according to the time it used. This system realizes intelligent control for a single room based on CAN-bus and gets the maximum energy-saving. It is proved that it can save heat more than 35% by comparing more similar rooms through two heating period. It has the promotion value in heating system of existing public building in North China.

Background Gastric cancer is one of the most common malignancies and a leading cause of cancer death. Complete resection is still the only treatment to offer a cure for patients with gastric cancer. Lymphadenectomy is the most important part of curative resection, but lymphadenectomy is also very difficult in gastric cancer surgery. The aim of this study was to report our 3-step method for lymphadenectomy and clarify its safety and value in gastric cancer. Study Design A total of 120 consecutive patients underwent our 3-step method for lymphadenectomy at the Second Affiliated Hospital Zhejiang University College of Medicine between February 2006 and July 2007. The main surgical procedure was performed from right to left and from caudal to cranial. Clinical factors, surgical variables, postoperative morbidity, and hospital (30-day) mortality were analyzed retrospectively. Results Total gastrectomy was performed in 41 patients; combined adjacent organ resection was performed in 9 patients. The mean operation time was 201.8 minutes, and the mean blood loss was 376.7 mL. The median postoperative hospital stay was 14.9 ± 4.3 days. A total of 3,569 lymph nodes (LNs) were removed and examined, and 2,879 were negative. More than 15 LNs were examined in all 120 patients. The median number of examined LNs was 29 (range 17 to 64; mean 29.7 ± SD 9.6) per patient, and the median number of positive LNs was 5 (range 0 to 37; mean 5.8 ± SD 7.1) per patient. The overall incidence of postoperative complications was 10.8%, and the rate of hospital death was 0%. The median follow-up period for those patients was 34.3 months (range 10 to 53 months), and the overall 3-year survival rate was 40.6%. Conclusions The 3-step method for lymphadenectomy is easy to perform and is a safe and useful procedure for gastric cancer surgery.

Combined factor V (FV) and factor VIII (FVIII) deficiency (F5F8D) is a rare autosomal recessive bleeding disorder caused by mutations in LMAN1 and MCFD2 gene. Though characterized with deficiencies of both FV and FVIII, it failed to lead to more severe bleeding than single defect of FVIII in similar degree. Our study on F5F8D patients revealed that mild decrease of FV and FVIII had counteractive effect on blood coagulation. Out of 5 subjects investigated, three showed potent thrombin generation as observed in thrombin generation assay (TGA), with peak heights ranging from 138 nM to 166 nM, compared with 81 nM in normal plasma when coagulation was initiated with 1pM TF. The same trend was seen when the TF concentration was increased to 5 pM. Supplement of FV and FVIII, however, demonstrated distinct impact in TGA, with FVIII addition inducing more thrombin generation whereas higher FV level failed to further boost thrombin generation despite the shortened lag time. FV is a Janus-faced protein and suppresses blood coagulation by protecting TFPI from degradation.Similar to patients with severe FV deficiency, both total and free TFPI levels also decreased slightly in F5F8D patients. Total TFPI levels decreased from healthy donors (65.95±8.35 ng/mL) to F5F8D patients (65.79±12.99 ng/mL), to severe FV-deficient patients (51.30±11.15 ng/mL, P=0.037). A more pronounced trend was observed for free TFPI levels, as free TFPI in healthy controls were 12.68±2.91 ng/mL, higher than those in F5F8D (4.73±1.31 ng/mL, P=0.004), and in severe FV-deficient patients (3.81±1.03 ng/mL, P=0.004).The lowered TFPI in patients with F5F8D may neutralize the impact of FV and FVIII deficiency on blood coagulation. Desmopressin (DDAVP) increases endogenous FVIII and is used in the management of mild hemophilia A patients. In current study, 4 patients with F5F8D were treated with DDAVP. The administration of DDAVP saw no elevation of FV yet the increase of FVIII. The mean basal FV and FVIII levels were 11.5±3.4% and 15.1±4.8% respectively. The peak value of FVIII levels rose to 66.1±20.5% 30 minutes after the administration, and was sustained at two-folds of the baseline four hours post administration. The distinctive changes brought by combined FV and FVIII deficiencies on blood coagulation functions indicates the lone FVIII replacement without FV supplement might be sufficient in bleeding management of patients with F5F8D. DDAVP can be considered as a potential substitute for FVIII concentrate in the treatment of F5F8D patients. Disclosures No relevant conflicts of interest to declare.

Aimed at solving the optical defects of the traditional handled laser-cleaners, such as inhomogeneous power distribution, large caliber, high cost of range-finder and complex control system, the feature of the laser beam is analyzed, the formula of the power average density distribution in the fiber laser-cleaner are discussed, and a new optical shaping method is presented in this paper. In order to regulate the infrared gauss laser beam and redistribute the high density power from the center to the edge, the system simulation utilized a ray tracing method which contains a Kepler telescope system made by two aspherical lenses. As a result, the laser power was compensated and homogenized; the lap joint ratio of laser patch was reduced; and the cleaning speed can be increased. Based on the features of the free-space optical system, the multi-layer optical design method was utilized. The traditional laser range-finder was replaced by the optical focusing design which could clearly point out the best working area, reduce a lot of optic-electronic elements, and simplify the structure of the cleaner’s output-end. On the other hand, this method would not cause any losses of the working laser power. Besides, a visible direction light was added into the invisible infrared working laser for safety.

Introduction: Clostridium difficile is a common cause of nosocomial diarrhea, especially in elderly patients. This study aimed to analyze the clinical features and assess the risk factors associated with Clostridium difficile infection (CDI) in elderly hospitalized patients. Methodology: A retrospective case-control study was conducted among elderly hospitalized patients (> 60 years of age) in a Chinese tertiary hospital between 2010 and 2013. Fifty-two CDI patients and 150 randomly selected non-CDI patients were included in the study. Clinical features of CDI and non-CDI patients were compared by appropriate statistical tests. Logistic regression analyses were performed on a series of factors to determine the risk factors for CDI among the elderly hospitalized patients. Results: The elderly CDI patients showed higher leukocyte counts, lower serum albumin levels, longer duration of hospital stay, and higher mortality compared to the non-CDI patients. The proportion of patients admitted to the intensive care unit or exposed to gastric acid suppressants was also significantly different (p < 0.05) between the two groups. Multivariate analysis indicated that serum creatinine (OR 1.004; 95% CI 1.001–1.008), surgical intervention (OR 6.132; 95% CI 2.594–14.493), the number of comorbidities (OR 2.573; 95% CI 1.353–4.892), gastrointestinal disease (OR 4.670; 95% CI 2.002–10.895), and antibiotic use (OR 6.718; 95% CI 2.846–15.859) were independently associated with CDI. Conclusions: This study revealed several risk factors for CDI among elderly hospitalized patients. These findings will increase the knowledge concerning this disease and provide information regarding the control and prevention of CDI in the elderly.

In this paper, we study on the navigating bahevior of CRFNFP[1]-based agricultual robots in real scenes. We designed two sets of experiments and three navigating system with different configuration of software for comparative study. The experimental results indicate that, compared to the traditional local-map-based navigating systems, the CRFNFP-based navigating system does enhance the long-range perception for mobile robots and helps planning more efficient paths for the navigation.

Epilepsy or seizures are often observed in patients with diabetes mellitus (DM), and an emerging association between the two diseases is more than coincidental based on recent research. Approximately 25% of patients with DM experience different types of seizures. Furthermore, diabetic patients who experienced episodes of DKA also have seizures more frequently. The precise pathogenesis of seizures in the diabetes patient remains undetermined. Currently, the leading hypotheses in the literature suggest that multiple physiological factors, such as immune abnormalities, microvascular lesions in the brain, local brain damage, metabolic factors and gene mutation, may contribute to this condition. To date, there are no international criteria for the diagnosis and treatment of this condition. Although it is commonly assumed that antiepileptic drugs are necessary, most of the partial epilepsy patients with non-ketotic diabetes are resistant to frequently used antiepileptic drugs. In contrast, partial status epilepticus can be treated by diazepam, and carbamazepine is reported to be effective to some DM patients with epilepsy. However, anti-diabetic drugs are considered to be the most important factors in the treatment of this condition. When the blood glucose levels gradually return to normal levels, patients can no longer generate seizures even when antiepileptic drugs are discontinued.

In 2010,we proposed CRFNFP[1] algorithm to enhance long-range terrain perception for outdoor robots through the integration of both appearance features and spatial contexts. And our preliminary simulation results indicated the superiority of CRFNFP over other existing approaches in terms of accuracy, robustness and adaptability to dynamic unstructured outdoor environments. In this paper, we further study on the comparison experiments for navigation behaviors of robotic systems with different scene perception algorithms in real outdoor scenes. We implemented 3 robotic systems and repeated the running jobs under various conditions. We also defined 3 creterion to facilitate comparison for all systems: Obstacle Response Distance (ORD), Time to Finish Job (TFJ), Distance of the Whole Run (DWR). The comparative experiments indicate that, the CRFNFP-based navigating system outperforms traditional local-map-based navigating systems in terms of all criterion. And the results also show that the CRFNFP algorithm does enhance the long-range perception for mobile robots and helps planning more efficient paths for the navigation.

Cooperation and exchange activities have become indispensable part of R&D, and performance of it is also concerned by many scientists and managers.

The data are collected for Lingo program running. According to the optimized result, the domestic airfreight transport network is discussed. The analysis aiming at changing some constraints to meet different customers’ and suppliers’ requirements are processed. The results are found practicable.

Field Server is environmental monitoring equipment which can construct wireless sensor network. Needs of Field Servers is the more in the further places and especially extreme environments. Field Servers for extreme environmental should be small, light and long lifetime. We deployed a prototype of the Field Server in Namche, Himalaya to test the reliability. Combination of the functions may make troubles under unexpected conditions. If almost all devices can be controlled remotely, Field Server can be maintained by changing inside condition like homeostasis of human body.

Mode analysis of the terahertz wave generated by 0.14 THz overmoded surface wave oscillator (SWO) (overmoded ratio D/ 3) is theoretically accomplished and experimentally validated. At first, longitudinal field-expansion method for mode analysis is established aiming at overmoded Cherenkov devices. Then this method is used to analyze the theoretical mode content of 0.14 THz SWO in detail based on the simulation results of electric field extracted from a 2.5-dimensional PIC (particle-in-cell) code. Results show that the mode content of terahertz wave in different characteristic regions of the oscillator is varied due to the mode conversion, and it is dominated by TM02 and TM03 modes accompanied by a small quantity of TM04 mode at the output. Finally, the energy distribution in the near-field radiation of 0.14 THz SWO is obtained by image-displaying method. The experimental result is reasonably in accord with the theoretical distribution calculated from the mode analysis results under experimental conditions, testifying the feasibility of longitudinal field-expansion method for the mode analysis and the correctness of its results.

Based on surface-wave oscillator (SWO), the high power 0.34 THz source using over-moded structure is studied. The attention is paid to the influence of the parameters of the slow-wave structure (SWS) on the dispersion curve, and then the SWS is optimized. According to the simulation results, the size of SWS and the requirements for the accuracy in the SWS machining are confirmed. Finally, the source is simulated by the particle-in-cell method. Numerical results show that the structure is capable of radiating a terahertz signal with a frequency of 0.34 THz and a maximum output power of about 7.8 MW. Moreover, the structure works in the state of an SWO stably. The research of the SWS is the foundation of the design of 0.34 THz source, and it is also very meaningful for the realization of the source in engineering.

A 0.14 THz high-power terahertz pulse detector based on hot electron effect in semiconductors is designed in this paper. First, the working principle of the detector is analyzed and its relative sensitivity is derived according to the structural characteristics of the detector. Then a three-dimensional finite-difference time-domain method is used to simulate the voltage standing wave ratio (VSWR) and relative sensitivity in a linear region. With optimized structural parameters, the VSWR of the designed detector is less than 1.3 while the relative sensitivity is about 0.6 kW-1, fluctuating no more than 10% in a frequency range of 0.13—0.16 THz. Subsequently discussed are the effect of Joule heat on the detector, and the relation between variation ratio of the output voltage and terahertz pulse duration. Finally the detecting simulations of the detector and its analysis results show that the detector with response time of picosecond-leval can handle a maximum power of about 2.2 kW, while the maximum power of its linear working region reaches tens of watts, so it can accomplish the direct measuring of 0.14 THz high-power terahertz pulses with nanosecond-level durations, increasing the accuracy of power measurement.
