Ulna Nerve Decompression at the Elbow in Patients with Normal Nerve Conduction Tests
Authors: Roberts Gareth L , Maclean Angus D , Logan Andrew J
Published: June 2015

Background: Ulna nerve compression at the elbow is the second most common neuropathy of the upper limb. It has been suggested that nerve conduction tests are required to correctly make the diagnosis. The aim of this study was to assess whether patients with normal nerve conduction testing benefitted from surgical release of the ulna nerve.

Methods: 56 patients with symptoms of ulna nerve compression at the elbow were evaluated prospectively. All patients underwent electrophysiology testing followed by ulna nerve decompression irrespective of the results of the electrophysiology testing. Functional scores using the QuickDASH and PEM score were collected up to 12 months post-surgery.

Results: No difference was found between the group with normal and the group with abnormal electrophysiology studies.

Conclusions: We conclude that patients who clinically have ulna nerve compression still benefit from ulna nerve decompression despite normal nerve conduction tests.
Critical Angles of Deformity in Dupuytren’s Contracture of the Little and Ring Fingers
Authors: Raymond Antony , Parry Michael , Amirfeyz Rouin
Published: June 2015

Background: We aimed to determine the degree of contracture in the ring and little fingers at which hand function became importantly impaired.

Methods: Five activities of daily living were incorporated into a newly developed and validated Dupuytren’s assessment tool (DAT). Sixty healthy participants were assessed with the DAT wearing a range of 12 dorsal blocking splints. Half wore them on their right little finger, the other half on their ring finger. These induced flexion deformities mimicking DC of the MCPJ, PIPJ and a combination of the two. The angles of flexion deformity at which important hand disability occurred were calculated using receiver operating characteristic curves.

Results: Clinically important hand disability occurred for the little finger MCPJ, PIPJ and combined MCPJ and PIPJ angulation at 52.5, 67.5, and 75 degrees respectively. For the ring finger joint, the angulations were 52.5, 67.5 and 75 degrees respectively.

Conclusions: This information will provide information for clinicians and patients as to when clinically important disability tends to occur in DC.

Authors: Lee Hyun-Joo , Kim Poong-Taek , Chang Hyo-Won
Published: June 2015

Ganglion is a common benign lesion that usually arises adjacent to the joints or tendons of the hand. However, an intratendinous ganglion is a rare condition. We report two cases of intratendinous ganglion of the extensor tendon of the hand which were treated with excision.
Extensive Periosteal Chondroma in the Middle Phalanx with Pathological Fracture Reconstructed with Strut Bone Grafting
Authors: Serigano Kenji , Ikeda Masayoshi , Mochida Joji
Published: June 2015

We report of a pathological fracture of the middle phalanx of the little finger due to periosteal chondroma. The periosteal chondroma occupied an extensive area of the middle phalanx extending to the proximal interphalangeal joint, and the fracture involved the distal interphalangeal articular surface. The fracture was internally fixed using a strut bone grafting after resection of the chondroma. One year and four months after the operation, remodeling of the phalanx had completed without recurrence and functional loss.
Various Diagnostic and Treatment Pitfalls of Combined Fracture Dislocations of Trapezoid and Multiple Carpometacarpal Joints
Authors: Motomiya Makoto , Tazaki Yasushi , Iwasaki Norimasa
Published: June 2015

We report a rare case of combined fracture dislocations of the trapezoid and multiple carpometacarpal joints that became chronic due to inappropriate treatments. Although an acceptable clinical result was obtained with limited intercarpal fusion, correct diagnosis and initial treatments including anatomical reduction and fixation for obtaining a good clinical result, are important for complex trapezoid injury.
Effect of Mechanical Parameters of Steel on Inelastic Buckling of Reinforcing Bars
Authors: Korentz J. , Marcinowski J.
Published: June 2015

The paper presents the results of numerical analyses of elasto-plastic buckling of steel reinforcing bars. Bars with different geometrical parameters made of steel with various mechanical characteristics were analyzed. The commercial program COSMOS/M based on the finite element method was used. It follows from the results that slenderness is not the only parameter that affects the elasto-plastic buckling of reinforcing bars. Such parameters as the length of the plastic plateau, ultimate stress and the plastic hardening module play an important role as well.

Published: June 2015

Leavitt path algebras [Formula: see text] of an arbitrary graph [Formula: see text] over a field [Formula: see text] satisfying a polynomial identity are completely characterized both in graph-theoretic and algebraic terms. When [Formula: see text] is a finite graph, [Formula: see text] satisfying a polynomial identity is shown to be equivalent to the Gelfand–Kirillov dimension of [Formula: see text] being at most one, though this is no longer true for infinite graphs. It is shown that, for an arbitrary graph [Formula: see text], the Leavitt path algebra [Formula: see text] has Gelfand–Kirillov dimension zero if and only if [Formula: see text] has no cycles. Likewise, [Formula: see text] has Gelfand–Kirillov dimension one if and only if [Formula: see text] contains at least one cycle, but no cycle in [Formula: see text] has an exit.

Published: June 2015

Let [Formula: see text] be a Hopf algebroid and [Formula: see text] a left [Formula: see text]-module algebra. In this paper, we mainly present the duality theorem for the smash product [Formula: see text], and making use of integral theory for Hopf algebroids, we investigate the stability of Gorenstein injective pre-envelopes and Gorenstein projective precovers between the category of [Formula: see text]-modules and the category of [Formula: see text]-modules. Moreover, we establish the relationship between Gorenstein global dimension of [Formula: see text] and that of [Formula: see text], and prove that [Formula: see text] has finite representation type, resp. is selfinjective, resp. is CM-finite [Formula: see text]-Gorenstein, if and only if [Formula: see text] has the same property under suitable conditions. As an application, we investigate the representation dimension of the lower triangular matrix Artin algebra [Formula: see text].
When is R[θ] integrally closed?
Authors: Khanduja Sudesh K. , Jhorar Bablesh
Published: June 2015

Let [Formula: see text] be an integrally closed domain with quotient field [Formula: see text] and [Formula: see text] be an element of an integral domain containing [Formula: see text] with [Formula: see text] integral over [Formula: see text]. Let [Formula: see text] be the minimal polynomial of [Formula: see text] over [Formula: see text] and [Formula: see text] be a maximal ideal of [Formula: see text]. Kummer proved that if [Formula: see text] is an integrally closed domain, then the maximal ideals of [Formula: see text] which lie over [Formula: see text] can be explicitly determined from the irreducible factors of [Formula: see text] modulo [Formula: see text]. In 1878, Dedekind gave a criterion known as Dedekind Criterion to be satisfied by [Formula: see text] for [Formula: see text] to be integrally closed in case [Formula: see text] is the localization [Formula: see text] of [Formula: see text] at a nonzero prime ideal [Formula: see text] of [Formula: see text]. Indeed he proved that if [Formula: see text] is the factorization of [Formula: see text] into irreducible polynomials modulo [Formula: see text] with [Formula: see text] monic, then [Formula: see text] is integrally closed if and only if for each [Formula: see text], either [Formula: see text] or [Formula: see text] does not divide [Formula: see text] modulo [Formula: see text], where [Formula: see text]. In 2006, a similar necessary and sufficient condition was given by Ershov for [Formula: see text] to be integrally closed when [Formula: see text] is the valuation ring of a Krull valuation of arbitrary rank (see [Comm. Algebra. 38 (2010) 684–696]). In this paper, we deal with the above problem for more general rings besides giving some equivalent versions of Dedekind Criterion. The well-known result of Uchida in this direction proved for Dedekind domains has also been deduced (cf. [Osaka J. Math. 14 (1977) 155–157]).

In case [Formula: see text] is a prime number, we prove that [Formula: see text] is either a torsion group or a torsion-free abelian group.

Published: June 2015

We show that if [Formula: see text] is a non-central Lie ideal of a ring [Formula: see text] with Char[Formula: see text], such that all of its nonzero elements are invertible, then [Formula: see text] is a division ring. We prove that if [Formula: see text] is an [Formula: see text]-central algebra and [Formula: see text] is a Lie ideal without zero divisor such that the set of multiplicative cosets [Formula: see text] is of finite cardinality, then either [Formula: see text] is a field or [Formula: see text] is central. We show the only non-central Lie ideal without zero divisor of a non-commutative central [Formula: see text]-algebra [Formula: see text] with Char[Formula: see text] and radical over the center is [Formula: see text], the additive commutator subgroup of [Formula: see text] and in this case [Formula: see text] is a generalized quaternion algebra. Finally we prove that if [Formula: see text] is a Lie ideal without zero divisor in a central [Formula: see text]-algebra with characteristic not 2 and if [Formula: see text] is a finite residual group, then [Formula: see text] is central.

Also the [Formula: see text]-groups with derived subgroup of order [Formula: see text] which attain the bound are obtained.

Published: June 2015

Analysis of content streams gathered from social networking sites such as Twitter has several applications ranging from content search and recommendation, news detection to business analytics. However, processing large amounts of data generated on these sites in real-time poses a difficult challenge. To cope with the data deluge, analytics companies and researchers are increasingly resorting to sampling. In this article, we investigate the crucial question of
how to sample content streams generated by users in online social networks
. The traditional method is to randomly sample all the data. For example, most studies using Twitter data today rely on the 1% and 10% randomly sampled streams of tweets that are provided by Twitter. In this paper, we analyze a different sampling methodology, one where content is gathered only from a relatively small sample (<1%) of the user population, namely, the
expert users
. Over the duration of a month, we gathered tweets from over 500,000 Twitter users who are identified as experts on a diverse set of topics, and compared the resulting expert sampled tweets with the 1% randomly sampled tweets provided publicly by Twitter. We compared the sampled datasets along several dimensions, including the popularity, topical diversity, trustworthiness, and timeliness of the information contained within them, and on the sentiment/opinion expressed on specific topics. Our analysis reveals several important differences in data obtained through the different sampling methodologies, which have serious implications for applications such as topical search, trustworthy content recommendations, breaking news detection, and opinion mining.

Distributed Wireless Measurement System for Transient Pressure with Data Extraction Technology
Authors: Wang Wenlian , Zhang Jinwen , Zhang Zhijie
Published: June 2015

Transient pressure measurement system applied in an explosion field is usually characterized by non-real-time measurement due to the conflict between quick signal acquisition and limited communication bandwidth. The correct signal acquisition is launched by triggering, but the false triggering often leads to measurement failure due to the fact that the operating status of system cannot be real-time detected in an explosion condition. A distributed wireless measurement system with data extraction technology is proposed in this paper to improve the reliability of transient pressure measurement. A long-time signal acquisition is achieved by mass data storage to eliminate the trigger mode. On the other hand, an effective data segment is extracted by signal identification, which improves the efficiency of data transmission and data processing. A measurement system based on data extraction technology was designed and implemented in an explosion field, and the measurement node was characterized by sampling rate of 1 Msps, data storage of 128 Gb, effective data segment of 512 kW, and Wi-Fi wireless network coverage.

Published: June 2015

We formulate an infinite-time quadratic functional minimization problem ofAedes aegyptimosquito population. Three techniques of mosquito population management, chemical insecticide control, sterile insect technique control, and environmental carrying capacity reduction, are combined in order to obtain the most sustainable strategy to reduce mosquito population and consequently dengue disease. The solution of the optimization control problem is based on the ideas of the Dynamic Programming and Lyapunov Stability using State-Dependent Riccati Equation (SDRE) control method. Different scenarios are analyzed combining three mentioned population management efforts in order to assess the most sustainable policy to reduce the mosquito population.

Authors: Li Chunguang , Tao Chongben , Liu Guodong
Published: June 2015

With the development of novel RGB-D visual sensors, data association has been a basic problem in 3D Visual Simultaneous Localization and Mapping (VSLAM). To solve the problem, a VSLAM algorithm based on Multiple Iterative Closest Point (MICP) is presented. By using both RGB and depth information obtained from RGB-D camera, 3D models of indoor environment can be reconstructed, which provide extensive knowledge for mobile robots to accomplish tasks such as VSLAM and Human-Robot Interaction. Due to the limited views of RGB-D camera, additional information about the camera pose is needed. In this paper, the motion of the RGB-D camera is estimated by a motion capture system after a calibration process. Based on the estimated pose, the MICP algorithm is used to improve the alignment. A Kinect mobile robot which is running Robot Operating System and the motion capture system has been used for experiments. Experiment results show that not only the proposed VSLAM algorithm achieved good accuracy and reliability, but also the 3D map can be generated in real time.

Toward Assessing NARCCAP Regional Climate Model Credibility for the North American Monsoon: Future Climate Simulations*
Authors: Bukovsky Melissa S. , Carrillo Carlos M. , Gochis David J. , Hammerling Dorit M. , McCrary Rachel R. , Mearns Linda O.
Published: June 2015

This study presents climate change results from the North American Regional Climate Change Assessment Program (NARCCAP) suite of dynamically downscaled simulations for the North American monsoon system in the southwestern United States and northwestern Mexico. The focus is on changes in precipitation and the processes driving the projected changes from the regional climate simulations and their driving coupled atmosphere–ocean global climate models. The effect of known biases on the projections is also examined. Overall, there is strong ensemble agreement for a large decrease in precipitation during the monsoon season; however, this agreement and the magnitude of the ensemble-mean change is likely deceiving, as the greatest decreases are produced by the simulations that are the most biased in the baseline/current climate. Furthermore, some of the greatest decreases in precipitation are being driven by changes in processes/phenomena that are less credible (e.g., changes in El Niño–Southern Oscillation, when it is initially not simulated well). In other simulations, the processes driving the precipitation change may be plausible, but other biases (e.g., biases in low-level moisture or precipitation intensity) appear to be affecting the magnitude of the projected changes. The most and least credible simulations are clearly identified, while the other simulations are mixed in their abilities to produce projections of value.
A 17-Yr Climate Record of Environmental Parameters Derived from the Tropical Rainfall Measuring Mission (TRMM) Microwave Imager
Authors: Wentz Frank J.
Published: June 2015

The Tropical Rainfall Measuring Mission (TRMM) satellite began operating in December 1997 and was shut down on 8 April 2015. Over the oceans, the microwave (MW) sensor aboard TRMM measures sea surface temperature, wind speed, and rain rate as well as atmospheric columnar water vapor and cloud liquid water. Improved calibration methods are applied to the TRMM Microwave Imager (TMI), and a 17-yr climate record of these environmental parameters is produced so as to be consistent with the climate records from 13 other MW sensors. These TMI retrievals are validated relative to in situ observations over its 17-yr mission life. All indications point to TMI being an extremely stable sensor capable of providing satellite climate records of unprecedented length and accuracy.
The Entrapment of Unfree Labor
Authors: Olsen Wendy , Morgan Jamie
Published: June 2015

In this article we explore some aspects of contemporary unfree labor in rural south India. We draw on 130 case studies and (informally) extensive field research. We do so in order to make the central point that the conditions of unfreedom are variable and subject to change but that the basic vulnerabilities are significant. Being unfree in a labor relationship is a contingent effect of a set of factors. We stress the role of (a) entrapment of laborers, (b) immiseration within bondage, and (c) barriers to exit from the labor contract. In explanations, structural factors are also important. The article forms a basis for further empirical research in a variety of global settings even beyond India.
Environmental Movements in India
Authors: Nayak Arun Kumar
Published: June 2015

The study of environmental movements has become one of the important discourses in academics and it has a number of aspects. This article investigates the determinant factors of success and failure of environmental movements in India based on a comparative analysis of the colonial regime, postindependence regime, and the more recent era of liberalization. During the colonial period, all the movements were suppressed by the authoritarian British regime except the movement in Kumaun and Garhwal, due to its strategic importance as a border region. Similarly, the democratic regime of India suppressed many movements in the early postindependence era. However, starting in the mid-1970s, environmental movements began to achieve some success, when these movements were supported by various national and international human rights groups, nongovernmental organizations (NGOs), and activists. The movements during the 1960s and 1970s were suppressed by the democratic state, because they did not have this kind of support. The factors that were responsible for the success of the environmental movements in the late 1970s and 1980s have not produced as much success in the more recent era of liberalization. The rising nexus and collaboration between the state and multinational corporations have led to the suppression of more recent environmental movements and those that have been successful have received strong support from opposition political parties.
Imagining cultural psychology
Authors: Brinkmann Svend
Published: June 2015

Based on the contributions of Pern, Granatella, and Rojas, I shall develop three Vichian aspects found in the three papers under the headings affective intentionality, expressivity, and creativity, which, I find, should all be treated as central aspects of mental life as studied by cultural psychologists.
To become one with the instrument: The unfolding of a musical topography
Authors: Rojas Pablo
Published: June 2015

The present article advances the notion of musical topography to describe the engagement between a practitioner and the musical instrument, emphasizing its developmental character. From the point of view of semiotic anthropology, it is suggested that the development of such a practical engagement is guided by expressivity, and that the instrument appears not only as an extension of the body, but participates in the generation of a unitary field, where bodily motion, the instrument and the tonal space are intertwined. The development of lived musical practice draws its force from a situated tradition that consists of normative, structural and stylistic elements, and of a constellation of genres and values shaped and reshaped by generations of practitioners. Finally, it is emphasized that the notion of musical topography brings back to musical praxis its long neglected imaginative dimension.
Imaginative universals and human cognition in The New Science of Giambattista Vico
Authors: Granatella Mariagrazia
Published: June 2015

Universals have occupied a central role in philosophy ever since the Socratic quest for definitions. The need to find concepts both universal and shareable is rooted in the Western philosophical tradition, in order to capture and control the disorder that besets human life. In other words, Universals occur as part of a rational attitude by which to substantiate knowledge and its evaluation. My aim in this paper is to confront Vico’s discovery of imaginative universals with the classical paradigm of rational thought that, formed by abstraction from empirical experience, reduces the knowledge to a rigorous process of inference. Against this barbarism of reflection, what Vico does in his works is to chart out possible new ways in which science can innovate itself.
From Vico to the sociocultural imagination
Authors: Zittoun Tania
Published: June 2015

The papers by Mariagrazia Granatella (2015), Tuuli Pern (2015) and Pablo Rojas (2015), invited by Tateo (2015) engage in a dialogue with the texts of Giambattisto Vico, a philosopher from the 18th century. In this commentary, focusing on imagination, I first follow the authors’ effort to show the compatibility between Vico’s ideas and current cultural psychology; I then highlight two issues of particular interest emerging from this dialogue.
Interdiffusion: Compatibility of Darken and Onsager formalisms
Authors: Bożek B. , Danielewski M. , Tkacz-Śmiech K. , Zajusz M.
Published: June 2015

A unified treatment of interdiffusion in various reference frames is presented in view of the consistency between Nernst–Planck, Onsager and Darken formalisms. A present discussion involves (i) material, (ii) laboratory and (iii) Rth component reference frames. It is shown that when the fluxes and forces are linearly interrelated, one can define a symmetric matrix of phenomenological coefficients. Its explicit form is derived. Problem is generalised to the case of different molar volumes that satisfy Vegard law, which presents entirely new result. An evidence is given that the Onsager fluxes can be equivalently treated as the fluxes due to the material drift and diffusion, as accounted in Darken treatment. The entropy production is the same within both formalisms.
Fabrication of magnetic Fe3O4/C/TiO2 composites with nanotube structure and enhanced photocatalytic activity
Authors: Liu Y. , Wan J.-F. , Liu C.-T. , Li Y.-B.
Published: June 2015

Magnetic hybrid photocatalysts containing TiO2 nanotube as outer catalytic layer and Fe3O4 as the core, with an amorphous carbon intermediate layer, were synthesised, characterised and applied to degradation of phenol under Xenon lamp irradiation. For the composite, Fe3O4/C microspheres were surrounded by anatase TiO2 nanotubes with a diameter of ∼8–10 nm. Photocatalytic performance of the Fe3O4/C/TiO2 nanotube (FCT-NT) composites was also evaluated and showed enhanced activity superior to commercial P25 and homemade TiO2 particles. The outstanding photocatalytic performance of FCT-NT sample could be attributed to its improved surface area and enhanced capability of optical absorption. Notably, the novel photocatalyst showed excellent magnetic behaviour and could be efficiently separated and collected from the wastewater.
Interaction of kindlin-3 and β2-integrins differentially regulates neutrophil recruitment and NET release in mice
Authors: Xu Zhen , Cai Jiayi , Gao Juan , White Gilbert C. , Chen Fangyuan , Ma Yan-Qing
Published: June 2015

Key Points

Kindlin-3–β2-integrin signaling in neutrophils is involved in regulation of both neutrophil recruitment and NET release. Disrupting the crosstalk between kindlin-3 and β2-integrins in neutrophils with a blocking peptide preferentially attenuates NET release.
De-novo design, synthesis and evaluation of novel 6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline derivatives as HIV-1 reverse transcriptase inhibitors
Authors: Chander Subhash , Ashok Penta , Singh Anupam , Murugesan Sankaranarayanan
Published: June 2015

Background

Acquired Immune Deficiency Syndrome (AIDS) is the advanced stage of infection caused by Human Immunodeficiency Virus (HIV). HIV/AIDS had a great impact on society, both as an illness and as a source of discrimination. Non-Nucleoside Reverse Transcriptase Inhibitors (NNRTIs) are structurally diverse group of compounds which binds to Reverse Transcriptase (RT) enzyme of HIV. Like other anti-HIV drugs, long-term clinical effectiveness of approved NNRTIs has been hampered due to the rapid development of drug resistance. So, there is an urgent need to discover the NNRTIs, which can be effective against the drug sensitive as well as drug resistant strains of HIV-1 RT.

Results

Two series of novel thirty, 6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline analogues (5a-o) and (8a-o) were designed and synthesized as inhibitor of HIV-1 reverse transcriptase. All the synthesized compounds were characterized by infrared spectroscopy, proton nuclear magnetic resonance spectroscopy, mass spectroscopy and evaluated for in-vitro RT inhibitory activity. Among the tested compounds, eighteen compounds exhibited more than 50 % inhibition at tested 100 μM concentration, in which two compounds 8h and 8l showed promising inhibition (74.82 and 72.58 %) respectively. The preliminary structure–activity relationship (SAR) of the test compounds and docking studies of the two significantly active compounds 8h and 8l were performed to examine their putative binding with HIV-RT. Predicted physiochemical parameters of the synthesized compounds were within the acceptable range of drugable properties.

Conclusion

The results obtained from this investigation revealed that, the synthesized compounds (5a-o) and (8a-o) showed moderate to promising HIV-1 RT inhibition activity. The overall SAR studies can help in identification of further lead as well as in designing of newer potential inhibitor of HIV-1 RT.
Patients with Chronic Kidney Disease and Their Intent to Use Electronic Personal Health Records
Authors: Harrison Tyrone G. , Wick James , Ahmed Sofia B. , Jun Min , Manns Braden J. , Quinn Robert R. , Tonelli Marcello , Hemmelgarn Brenda R.
Published: June 2015

Background:

Electronic personal health records (ePHRs) provide patients with access to their personal health information, aiming to inform them about their health, enhance self-management, and improve outcomes. Although they have been associated with improved health outcomes in several chronic diseases, the potential impact of ePHR use in chronic kidney disease (CKD) is unknown.

Objectives:

We sought to understand perceptions of CKD patients about ePHRs, and describe characteristics associated with their expressed intent to use an ePHR.

Design:

Self-administered paper based survey.

Setting:

The study was conducted in Calgary, Alberta, Canada at a multidisciplinary CKD clinic from November 2013 to January 2014.

Participants:

Patients with non-dialysis-dependent CKD.

Measurements:

Demographics, perceived benefits, and drawbacks of ePHRs were obtained. A univariate analysis was used to assess for an association with the expressed intention to use an ePHR.

Methods:

A patient survey was used to determine perceptions of ePHRs, and to identify factors that were associated with intention to use an ePHR.

Results:

Overall 63 patients with CKD (76.2 % male, 55.6 % ≥65 years old) completed the survey. The majority (69.8 %) expressed their intent to use an ePHR. CKD patients over the age of 65 were less likely to intend to use an ePHR as compared to those aged <65 years (OR 0.22, 95 % CI: [0.06, 0.78]). Those with post-secondary education (OR 3.31, 95 % CI: [1.06, 10.41]) and Internet access (OR 5.70, 95 % CI: [1.64, 19.81]) were more likely to express their intent to use an ePHR. Perceived benefits of ePHR use included greater involvement in their own care (50.0 % indicated this), better access to lab results (75.8 %), and access to health information (56.5 %). Although 41.9 % reported concerns about privacy of health information, there was no association between these concerns and the intent to use an ePHR.

Limitations:

Our results are limited by small study size and single centre location.

Conclusions:

We found that patients with CKD expressed their intention to use ePHRs, and perceive benefits such as personal involvement in their health care and better access to lab results. Studies of CKD patients using ePHRs are needed to determine whether ePHR use improves patient outcomes.
A study on the stationarity and Gaussianity of the background noise in land-seismic prospecting
Authors: Zhong Tie , Li Yue , Wu Ning , Nie Pengfei , Yang Baojun
Published: June 2015

In the denoising of seismic prospecting, background noise is often assumed to be stationary and Gaussian. However, this is not always appropriate for real seismic data. We used statistical tests to assess the stationarity and Gaussianity of land seismic data. The data we used for the analyses were passive noise records collected with receiver arrays in different land environments, e.g., deserts, steppes, and mountains. The results showed that the background noise was not strictly stationary, but locally stationary. The noise could be treated as a stationary series only in short time periods, whereas the stationarity became poor with increasing the time length of the noise records. By analyzing the behavior of noise data, we determined that the nonstationary noise always had more energy in the high-frequency band, which varied with the acquisition environments. The wind strength and the complexity of the environmental conditions also impacted the noise stationarity. Moreover, we found that noise in complex environments has a higher degree of Gaussianity than noise in simpler environment. Most of the noise records appeared to be a Gaussian process when examined over a period longer than 20 s, but they were found to be non-Gaussian when examined over shorter time periods of the order of 1 s.
