Ikonosfera kurortu górskiego. Przyczynek do studiów nad historią uzdrowisk śląskich w XIX i XX wieku
Authors: Stanicka-Brzezicka Ksenia
Published: December 2020

One of the phenomena within the cultural construct created around the mountains was from the beginning of the nineteenth century the rise of resort culture. An extremely important element of this emerging resort culture was the development of iconography (pictorial representations), which — having originated in painting and then growing thanks to the spread of graphic techniques and the industrialisation of reproduction technologies — became a mass-scale phenomenon. Tourism began to generate a demand for various types of souvenirs and pictures made with the help of various techniques and materials (illustrated publications, engravings, photographs, postcards, dioramas as well as painted or engraved pottery or glass). It also became an impulse for the production of various components of resort culture, including advertising brochures and leaflets; posters and signboards, which became an increasingly familiar part of the urban iconosphere; shop windows; newspapers and magazines with advertising inserts; and even graphic layout of restaurant menus or hotel bills; finally, small architectural forms complementing big resort ensembles. This phenomenon should be viewed in many contexts — social transformations, especially social reception of visual messages, growth of resorts, development of medicine, technical infrastructure and many other. So far research into resorts has focused largely on an earlier period, encompassing the nineteenth century. However, the first half of the twentieth century has left a significant mark in the tourist space, and, above all, a lot of visual evidence. All this — from the oldest, eighteenth-century voyages pittoresques to twentieth-century “modern” advertisements of places, sites and events — can be used as a basis for research into pictorial culture and its analyses. Naturally, the mountains are one of the most important elements of this iconography. They are its main protagonist, sometimes a background or backstage. They are a real element of local topography or a symbol and archetype. The phenomenon can be observed also in Silesia, in the resorts of the Giant Mountains and the Kłodzko Valley, also in Polanica, when a joint-stock company was set up to manage and expand the resort. The article presents the components and history of increasingly professional marketing strategies pursued by the local authorities and management of the various mountain resorts in Silesia from the nineteenth century until the first half of the twentieth century. In addition, the author analyses image as a form of message as well as the power of visual information in the context of reflections on the popularisation of the mass media and information explosion, researched today within the framework of visual sociology, visual anthropology and visual culture studies.

Authors: Sari Fesdia , Lestari Sri , Gustia Rina , Asri Ennesta , Tofrizal Tofrizal
Published: December 2020

Background: Seborrheic keratosis is a benign epidermal skin tumor caused by sun exposure, virus, and genetic factor. Human papillomavirus (HPV) infection presumed to have an important role in seborrheic keratosis. Protein p53 is a protein produced by tumor suppressor gene. There has been no research that correlates of HPV with p53 increase in seborrheic keratosis. Purpose: To prove the correlation between HPV and increased p53 expression in seborrheic keratosis. Methods: This study is an analytic cross-sectional comparative study. Samples were taken using a consecutive sampling method. There were 22 seborrheic keratosis patients recruited as the research sample. HPV were detected using the polymerase chain reaction (PCR), and p53 expression were detected using the immunohistochemistry examination. Result: The mean age of seborrheic keratosis patients in this study was 54.36±10.09 years, and they were predominantly males (54.5%). HPV were found in 86.4% of the seborrheic keratosis patients. The P53 expression (+) were 77.3%, (++) were 13.6%, and (+++) were 9.1%. All of the seborrheic keratosis with increased  p53 expression had positive HPV results, but with no significant results (p=0.600). Conclusion: There were no correlation between HPV with increased  p53 expression in seborrheic keratosis patients.

Authors: Putera Edward Muliawan , Widodo Widodo , Mardiana Nunuk
Published: December 2020

Complications such as anemia and its clinical consequences arise as chronic kidney diseases progress,. One renal anemia pathophysiology is a disruption of iron metabolism, regulated by the main iron exporter hormone, hepcidin. Chronic kidney disease patients were constantly in an inflammatory state, represented by an increased in C-reactive protein. This inflammatory state would facilitate the liver to secrete hepcidin, which would subsequently follow a decrease of iron circulation, thus resulting in functional iron deficiency. Both acute phase reactants which used thoroughly as markers in tropical and infectious diseases, had their own roles in chronic kidney disease. The correlation of c-reactive protein and hepcidin in chronic kidney disease patients was still controversial. To analyse the relationship between c-reactive protein and hepcidin in non-dialysis chronic kidney disease patients. We conducted an observational cross-sectional study with 40 non-dialysis chronic kidney disease patients who met the inclusion and exclusion criteria. Patients were enrolled with consecutive sampling and were examined for serum c-reactive protein and hepcidin levels.A total of forty subjects (67.5% male with mean age of 50.23 ± 1.04 years) were eligible for enrolment in this study. The most comorbid factor was hypertension (62.5%). The common stage for chronic kidney disease was stage 3 (40%). The mean hemoglobin value was 10.74 ± 0.36 g/dL, mean blood urea nitrogen was 39.98 ± 29.59 mg/dL, and serum creatinine of 4.12 ± 3.39 mg/dL. Mean serum c-reactive protein levels were 3.52 ± 5.13 mg/l. Mean hepcidin level were 94,03 ± 95,39 ng/ml. Serum C-reactive protein levels correlated positively (r=0.487) and significantly (p-value=0.001) with serum hepcidin value. C-reactive protein and hepcidin was significantly correlated in non-dialysis chronic kidney disease patients.

Published: December 2020

The diagnosis of childhood tuberculosis remains a challenge worldwide. The GeneXpert MTB/RIF test, a rapid Mycobacteria tuberculosis diagnostic tool, was recommended for use in children. No pediatric studies of GeneXpert MTB/RIF assessing pulmonary tuberculosis within a hospital setting has been done in Indonesia. We evaluated the performance of the GeneXpert MTB/RIF test compared with sputum culture on Lowenstein-Jensen (LJ) for the diagnosis of childhood pulmonary tuberculosis. This study was conducted in pediatric respirology inpatient and outpatient Dr. Soetomo Hospital, a tertiary care facility in Surabaya between June and August 2015 with a cross-sectional design. We consecutively enrolled 27 children aged 3 months to 14 years who had history of close contact with adult tuberculosis patients and showed symptoms of pulmonary tuberculosis. Sputum collection was performed by induced sputum and three examination methods were performed (microscopic, GeneXpert MTB/RIF and sputum culture) simultaneously followed by a drug sensitivity test for specimens detected with MTB growth. The GeneXpert MTB/RIF test had a sensitivity of 100% (95% CI 100-100) and a specificity of 95% (95% CI 85-100). The positive predictive value for diagnosing pulmonary TB was 89% (95% CI 68-100), the negative predictive value was 100% (95% CI 100-100) and positive likelihood ratio was 20 (95% CI 2.82-128). The GeneXpert MTB/RIF test on one sputum sample rapidly and correctly identified all children with culture-confirmed pulmonary tuberculosis with high specificity. Similar results were obtained between GeneXpert MTB/RIF and sputum culture based on age groups and clinical manifestations. Rifampicin resistance were both detected in GeneXpert MTB/RIF and MTB sensitivity test

Published: December 2020

Food additives or food additives is one of the ingredients that are commonly used by humans to improve the taste, texture, appearance and color of food. Food additives are often used. The use of food additives or food additives aims to improve the quality of the final product and increase the shelf life of food ingredients. Food additives can be synthetic or derived from plants or animals, and they have been grouped by the World Health Organization and the Food and Agricultural Organization into three broad categories (flavor enhancers, enzymes and others), based on their function. However, at present the majority of people use food additives to the food excessively, thus creating a risk to health. Limit consuming food additives need to be considered when using it to be safe and not cause health problems. In addition, the majority of the food additive industry uses raw materials for food additives in the form of synthetic or artificial products so that if consumed in excess is harmful to health. One solution to reduce the consumption of synthetic food additives is to use natural food additives or natural food additives which when used are considered safe for consumption and certainly good for health

Published: December 2020

Wajah perkotaan di Indonesia kini sudah sangat berbeda dibandingkan dengan masa lalu, seperti halnya kota Yogyakarta. Kota pendidikan yang dahulu sarat dengan bangunan sekolah, saat ini harus berebut lahan dengan munculnya hotel dan mall yang kian subur. Melalui survei lapangan terhadap penghuni sekitar beberapa hotel dan mall, diperoleh fakta banyaknya keluhan mengenai kebisingan karena suara tempat hiburan, menyempitnya lahan jalan perkampungan warga, menghilangnya bangunan bersejarah, polusi udara dari bangunan hotel, dan pencemaran sumur oleh limbah operasional hotel. Di sisi lain dampak positif pembangunan mall dan hotel adalah berkembangnya ekonomi masyarakat di sekitar bangunan dan meningkatnya pemasukan daerah. Jika dicermati seberapa besar kemanfaatan yang diperoleh jika dibandingkan kerugian yang diterima masyarakat. Terlebih lagi kota pendidikan memiliki misi yang jauh lebih mulia dibandingkan dengan sekedar menjadi kota seribu hotel dan mall. Banyak kontribusi dari masyarakat dan juga memerintah dalam mengembalikan kota pendidikan kepada wajahnya semula. Diperlukan sinergitas yang dilandasi keinginan bersama untuk mewujudkan kota pendidikan yang nyaman serta ramah lingkungan.

Bagus-Jebrot Cave is located in Donomulyo District, Malang Regency which is in the Wonosari Formation which was formed in the Middle Miocene and Late Miocene. The purpose of this study is related to the developmental control that affects the cave passageways. The approach used is a geomorphological approach by conducting field measurements and documentation. The analysis used is frequency analysis and cross-section of the passage. Bagus-Jebrot Cave is a type of Epigenic Cave which is formed from surface water flowing into doline/sinkhole. It can be seen from the planview map that has a curvilinear passage pattern. The existence of groundwater flow also forms a physiographic cave passage with ellipse passage formation, asymmetrical ellipse, potholes, callops, solution notches, cups, solution pockets. Besides underground water flow, the development of the Bagus-Jebrot Cave aisle is related to the process of structural lifting and control. The lifting process is marked by the formation of 4 levels of the cave passage. While the formation of the canyon, joint passage, rectangular passage and keyhole is the result of structural control

We aimed to explore student and staff perceptions and experiences of a pilot COVID-19 asymptomatic testing service (P-ATS) in a UK university campus setting. This was a mixed-method study comprised of an online survey, and thematic analysis of qualitative data from interviews and focus groups conducted at the end of the 12-week P-ATS programme. Ninety-nine students (84.8% female, 70% first year; 93.9% P-ATS participants) completed an online survey, 41 individuals attended interviews or focus groups, including 31 students (21 first year; 10 final year) and 10 staff. All types of testing and logistics were highly acceptable (virus: swab, saliva; antibody: finger prick) and 94.9% would participate again. Reported adherence to weekly virus testing was high (92.4% completed ≥6 tests; 70.8% submitted all 10 swabs; 89.2% completed ≥1 saliva sample) and 76.9% submitted ≥3 blood samples. Students tested to ‘keep campus safe’, ‘contribute to national efforts to control COVID-19’, and ‘protect others’. 31.3% had high anxiety as measured by the Generalized Anxiety Disorder scale (GAD-7) (27.1% of first year). Students with lower levels of anxiety and greater satisfaction with university communications around P-ATS were more likely to adhere to virus and antibody tests. Increased adherence to testing was associated with higher perceived risk of COVID-19 to self (virus) and others (antibody). Qualitative findings revealed 5 themes and 13 sub-themes: ‘emotional responses to COVID-19’, ‘university life during COVID-19’, ‘influences on testing participation’, ‘testing physical and logistical factors’ and ‘testing effects on mental wellbeing’. Asymptomatic COVID-19 testing (virus/antibodies) is highly acceptable to students and staff in a university campus setting. Clear communications and support for mental wellbeing is likely to be important for testing uptake and adherence. Strategies are needed to facilitate social connections and mitigate the mental health impacts of COVID-19 and self-isolation.

Published: December 2020

Information and Communication Technology (ICT) is at the heart of the Smart City approach, which constitutes the next level of cities’ and communities’ development across the globe. Thereby, ICT serves as the gluing component enabling different domains to interact with each other and facilitating the management and processing of vast amounts of data and information towards intelligently steering the cities infrastructure and processes, engaging the citizens and facilitating new services and applications on various aspects of urban life - e.g. supply chains, mobility, transportation, energy, citizens’ participation, public safety, interactions between citizens and the public administration, water management, parking and many other use cases and domains. Hence, given the fundamental role of ICT in cities in the near future, it is of paramount importance to lay the ground for a sustainable and reliable ICT infrastructure, which can enable a city/community to respond in a resilient way to upcoming challenges whilst increasing the quality of life for its citizens. This paper constitutes a continuation of a series of research documents and standardization activities, which relate to the concept of Open Urban Platforms (OUP) and the way they serve as a blueprint for each city/community towards the establishment of an ICT backbone. Thereby, the current paper emphasizes on the aspects of sustainability and resilient ICT, whilst reporting on our latest activities and related developments in the research area.

Published: December 2020

Objective: The activities of the dairy goat group, in general, have not paid attention to the processing of livestock waste that comes from maintenance activities. For example, liquid waste from cleaning cages and livestock baths, dirt, urine, and milking activities. Dairy goat farm waste, if not appropriately managed can have a negative impact on the quality of underground water sources, surface water, and the surrounding environment. Application of the Advanced Ponds System (APS) system with at part of Algae Settling Ponds pool size of 3 m x 1.5 m x 1.5 m with a dose of 50 ml / m3 of probiotic liquid so that 337.5 ml was needed. This study aimed to improve the wastewater based on microbiological and psycochemical characteristics by treatment of advanced pond system with probiotic in dairy goat farm.

Methods: The variables observed were the content of microorganisms (Escherichia coli and Salmonella sp.) and physicochemical characteristics (Total N, Organic matter, temperature, pH, organic carbon, C/N ratio) of dairy goat farm wastewater in the APS system at part of Algae Settling Ponds. Data were analyzed by independent samples t-test analysis.

Results: The results showed that the addition of liquid probiotic had no significant effect on temperature, pH, and C / N ratio, but affected organic carbon, E. coli and Salmonella sp. (P<0.05).
Conclusions: Based on the research results, it can be concluded the addition of liquid probiotic through the application of the Advanced Ponds System with at part of Algae Settling Ponds can be used as a solution to accelerate the improvement of the quality of dairy goat farm wastewater.

Evaluation of Electrical Resistivity for Non-destructive Seepage Detection on an Urban Underground Diaphragm Wall
Authors: Yang Cai , Liu Shengdong , Ding Enjie , Yang Haiping , Xie Jingyan
Published: December 2020

With the continuous development of urban underground space, non-destructive methods for diaphragm wall leakage detection are becoming increasingly important. Recent studies have shown that the apparent resistivity, stimulated current, and self-potential can be used as indicator parameters for non-destructive diaphragm wall leak detection. The diaphragm wall seepage evaluation of a subway station was carried out using the above indicator parameters. The response characteristics of apparent resistivity, stimulated current, and self-potential were obtained before and after excavating the diaphragm wall. The results obtained by this study reveal that an area is very likely to be a seepage area when there are significant differences amongst the three measurement parameters. The self-potential is greatly affected by field interference; the stimulated current is a direct sign of seepage, and indicates that seepage occurs when the stimulated current increases; the apparent resistivity macroscopically indicates rupture or seepage in the diaphragm wall. The field experiment verified the feasibility of detecting diaphragm wall seepage using coupled analysis based on electrical resistivity and self-potential methods.
Self-potential Data Interpretation for Two Co-axial Structures Utilizing the RMS Parameter
Authors: Essa Khalid S. , Diab Zein E. , Elhussein Mahmoud
Published: December 2020

We have developed an algorithm to obtain the model parameters for two co-axial structures from self-potential data. The method uses the first numerical horizontal derivatives calculated from the observed self-potential anomaly employing filters of sequential window lengths (s-values) so as to gauge the model constraints for the shallow and deep structures. In addition, this algorithm uses a standard inversion method for solving a non-linear equation based on the lowest root-mean-square (RMS) error of the estimated model parameters. The body constraints are the depth, polarization angle and electric dipole moment of each structure. Our approach models the self-potential dataset as an aggregation of spheres, horizontal cylinders, and vertical cylinders. These simple bodies are used to approximate, without a priori expectations, the furthermost plausible position and/or area of intersection. In other words, the bodies are used to estimate the true values of the source parameters for the two-co-axial bodies at different s-values. Minimizing the RMS error has the advantage of optimizing all model factors. The proposed technique is tested using a numerical model with and without noise and on self-potential field data acquired at a site in Germany. In all cases, the assessed body parameters are reasonable approximations of the known values.
Ground Penetrating Radar Attenuation Expressions in Shallow Groundwater Research
Authors: Paz Maria Catarina , Alcalá Francisco J. , Ribeiro Luís
Published: December 2020

The electromagnetic-wave attenuation coefficient determines the overall resolution and effective penetration depth of ground penetrating radar (GPR) surveys. Despite this relevance to the design of proper GPR surveys, the attenuation expressions are rarely used in the applied shallow groundwater research (SGR) literature. This work examines the status of the attenuation expressions in SGR. For this, 73 GPR case studies (in 47 papers), including some information concerning the attenuation variables and parameters, were selected to build a database. From these, 18 cases (in 10 papers) provided attenuation expressions and only 11 cases (in 4 papers) used those expressions. Two types of expressions were identified, physically based global ones that try to solve a broad (but not complete) range of environmental and field technical conditions, and non-global ones adapted for specific geological environments and resolution needed. The database analysis showed that both global and non-global expressions were used exclusively in low-loss media to report an attenuation range of 0.1–21.5 dB m−1by using common antenna frequencies in the 25–900 MHz range. The range of the attenuation expressions validity in SGR is biased because no surveys in variable-loss heterogeneous media and wider antenna frequency intervals could be compiled. The attenuation database generated seeks to improve the design of GPR surveys in SGR.
A Study on the Characteristics of Electromagnetic Radiation during Deformation and Failure of Different Materials Under Uniaxial Compression
Authors: Wang Qifei , Li Chengwu , Xie Beijing , Zhao Yuechao , Ai Dihao
Published: December 2020

The detection of electromagnetic radiation (EMR) during the fracture of solid materials such as rocks and coal has been widely used in seismic exploration and mine dynamic disaster prediction. As described in this paper, we conduct uniaxial compression tests on coal, cement, and glass materials to determine the characteristic EMR differences among materials. A band-stop filter based on the Fourier transform and the wavelet packet transform method are used to conduct signal denoising and analysis. Basic analyses of the pulse-time characteristics, energy distribution, cumulative energy, and waveform characteristics of EMR are conducted. The research results show that there is a strong corresponding relation between the loading time, loading stress and EMR energy. A large number of EMR events are released in rapid succession during the main rupture of coal and cement, while the EMR events are evenly distributed throughout the whole loading process of glass. For the same material, the maximum EMR amplitude increases with an increasing peak value of the stress. The EMR pulse waveform of coal and cement agrees well with predictions based on the theoretical formula of the electromagnetic dipole oscillation EMR generation mechanism. The paper provides further theoretical basis for understanding the mechanism of EMR, with great significance for improving coal mining safety.

Published: December 2020

The transient electromagnetic method (TEM) for boreholes uses fixed source loops to launch at excavation faces, and is able to realize the mobile reception of secondary fields in the boreholes and detections of low-resistance hazards. This method is known as high detection accuracy, due to the fact that the receiving points are close to the anomalies. However, the interpretation method for this device has not yet been perfected. The present study's goal was to realize the interpretations of boreholes TEM based on inverse transform algorithms of the TEM wave-fields and full waveform inversions. It was found that under the conditions of transient electromagnetic virtual wave-fields, the characteristics of the virtual wave-field time-distance curves of the two-dimensional device could be examined, and a corresponding dynamic correction algorithm was successfully obtained. The wave-field velocities were analyzed using an equivalent conductive plane method. Additionally, the pseudo-seismic inversions of the tunnel-borehole TEM data were realized using full waveform inversion technology. Then, the inversion results of the three-dimensional numerical simulations, flume physical simulations, and downhole field simulations were calculated. It was observed that good imaging results had been obtained for small-scale borehole radial anomalies. Finally, the proposed method was applied to the engineering practices in an underground coal mine in Shanxi Province. The practicability and effectiveness of the proposed method in the fine detection of the properties, forms, and scale of water-logged goaf roadways were successfully tested in the field. The research results indicated that the roadway-borehole transient electromagnetic detection method was complementary to the underground geophysical exploration and drilling, and could be effectively applied in the detection of water-logged goaf roadways.

The geological conditions of coal roadway excavation are complicated. Seismic advanced detection is strongly influenced by the loose circle of fractured rock surrounding the competent coal seam. However, the three-dimensional wave field characteristics of small fault advanced detection in the condition of the loose circle of coal roadway have not examined. In this paper, numerical modeling and field tests were conducted to address this knowledge gap. The results indicate that when a seismic source near the tunnel face is excited, the body waves and a Love channel wave propagate in the tunneling direction toward the small fault, then produces reflected body waves whose amplitude is relatively weak, and a reflected Love channel wave whose amplitude is relatively strong. When reflected body waves and the reflected Love channel wave enter the loose circle of surrounding rock, the former's signal is unrecognizable in seismic record; but the latter converts to a Love wave whose amplitude is strong in the loose circle of coal seam. The Love wave which has a large interval from other wave trains in the time domain is easily recognizable in seismic record, which makes it suitable for advanced detection of small fault. The signal-to-noise ratio of seismic record of X component is higher than those of Y component and Z component.

Quantitatively linking observations from independent non-invasive soil assessment methods enhances our ability to understand root zone processes. Electrical Resistivity Tomography (ERT) and X-ray Computed Tomography (CT) are two advanced non-invasive technologies routinely employed in soil science. ERT allows 4D process monitoring ( e.g., solute transport) and is sensitive to changes in moisture content (MC) and soil texture. X-ray CT is a higher resolution method used to appraise soil structure. We measured the variation of electrical resistivity and X-ray absorption with gravimetric moisture content (GMC) for two distinct soil types. Experimental results were compared with existing pedophysical relationships that express these dependencies. Based on the good fit between measurements and model predictions, we formulated a new pedophysical relationship that links directly the two soil properties. This will allow a direct translation between ERT and X-ray data for the study of root-zone parameters under well-defined experimental circumstances.

We present an approach for the estimation of ore processing residue volumes in historical mine waste dumps by the use of different geophysical methods in combination with mineralogical investigations. The stamp mill dump in the Harz mountains, Germany was examined with the methods electrical resistivity tomography (ERT), ground penetrating radar (GPR) and spectral induced polarization (SIP) flanked by mineralogical studies at many drilling points. The mineralogical results were used to calibrate the geophysical results and to distinguish between valuable and non-valuable waste material. With SIP we investigated individual profiles and took lab samples. These lab results emphasize the differences between the fine-grained tailings of clayey silt to silty sand in the top layer and the sandy tailings underneath in both resistivity and phase. From the GPR results we can distinguish between different layers and various backfillings in the first two meters due to the much higher resolution than the other methods. From ERT we achieved an overview about the dimension and inner structure of the dump and the boundary between the sandy residual material and the host rock. To estimate the volume of the residual body we carried out 2D inversion of all ERT profiles followed interpolation between the inverted profiles. From the drilling interpretation, the SIP lab results and the ERT field measurements we defined a resistivity threshold of 350 ohm-m for the ore processing residues to achieve a 3-dimensional body of the dump. The volume of this body was then corrected by a factor due to consideration of uncertainties, e.g., forest areas, inaccessible dump sections, small-scale anomalies (geological or different anthropogenic nature) and inversion coverage. As a result, we were able to calculate the volume of the ore processing residues which can be used further for the determination of the economic potential (remaining metal content).

Surface-based 2D electrical resistivity tomography (ERT) surveys were used to characterize permafrost distribution at wetland sites on the alluvial plain north of the Tanana River, 20 km southwest of Fairbanks, Alaska, in June and September 2014. The sites were part of an ecologically-sensitive research area characterizing biogeochemical response of this region to warming and permafrost thaw, and the site contained landscape features characteristic of interior Alaska, including thermokarst bog, forested permafrost plateau, and a rich fen. The results show how vegetation reflects shallow (0–10 m depth) permafrost distribution. Additionally, we saw shallow (0–3 m depth) low resistivity areas in forested permafrost plateau potentially indicating the presence of increased unfrozen water content as a precursor to ground instability and thaw. Time-lapse study from June to September suggested a depth of seasonal influence extending several meters below the active layer, potentially as a result of changes in unfrozen water content. A comparison of several electrode geometries (dipole-dipole, extended dipole-dipole, Wenner-Schlumberger) showed that for depths of interest to our study (0–10 m) results were similar, but data acquisition time with dipole-dipole was the shortest, making it our preferred geometry. The results show the utility of ERT surveys to characterize permafrost distribution at these sites, and how vegetation reflects shallow permafrost distribution. These results are valuable information for ecologically sensitive areas where ground-truthing can cause excessive disturbance. ERT data can be used to characterize the exact subsurface geometry of permafrost such that over time an understanding of changing permafrost conditions can be made in great detail. Characterizing the depth of thaw and thermal influence from the surface in these areas also provides important information as an indication of the depth to which carbon storage and microbially-mediated carbon processing may be affected.

The acoustic wave equation is an important basis for seismic wave propagation, imaging, and migration. This equation has led to the development of finite difference methods, but these methods are prone to numerical instability and grid dispersion problems, with the issue of dispersion being the most vital. Optimization methods can improve the accuracy across a large range of wavenumbers or frequencies. In this paper, we present a novel evolutionary optimization scheme for the acoustic wave equation. Our approach involves combining the fruit fly optimization algorithm (FOA) and sampling approximation (SA) to obtain the optimal difference operator for a wide range of wavenumbers. The difference coefficients are optimized to be extracted by the FOA, and the function of fitness, which is used to introduce an iterative process to determine the best smells, is evaluated by acoustic wave simulations. Based on the space-domain dispersion relation, we prove that the accuracy with which the absolute error is minimized is the same as that of the relative error. Within a given range of wavenumbers, we propose a fitness function by minimizing the absolute errors of the space-domain dispersion relation, and the dispersion analysis reveals that this scheme is superior to the Taylor-expansion scheme. We conduct two experiments by applying homogeneous and complex models, respectively. Further, the modeling results indicate that the fruit fly optimization approach in conjunction with sampling approximation preserve a higher accuracy for a small operator length and reduce the numerical artifacts.

We present a means of processing data from frequency-domain controlled-source electromagnetic method observations via a Nyquist diagram. For a controlled-source electromagnetic field in the frequency domain, the x component of the electric field and the y and z components of the magnetic fields were chosen for discussion. Typical 1-D models and a 3-D model, which have a single anomalous body embedded in a half space, have been used to calculate the complex electromagnetic fields. The corresponding Nyquist diagrams have been plotted and analyzed. The diagrams can reveal the magnitude-phase frequency characteristics of an electromagnetic field and can be used to guide data processing by considering the constraints of the intrinsic connection between amplitude and phase. The results further show that: (1) the Nyquist diagrams of both electric and magnetic responses, varying from low to high frequencies, are all characterized by continuous, single-direction, clockwise spiral curves; (2) for the magnetic field, the opening direction of the Nyquist curve is upward for the y and downward for the z components, regardless of the change in resistivity; (3) for the electric fields, the resistivity changes also lead the spiral structure to take on complicated shapes, such as a snail-like shape or a W, and the starting points of the Nyquist curves depend on the variations in the resistivity with depth. According to the aforementioned rules, we can obtain reliable and reasonably complex field data during the data processing of frequency-domain controlled-source electromagnetic method, which lays a foundation for 3-D frequency-domain data inversion.
