Iterated partial summations applied to finite-support discrete distributions
Authors: Koščová Michaela , Harman Radoslav , Mačutek Ján
Published: March 2020

The problem of iterated partial summations is solved for some discrete distributions defined on finite supports. The power method, usually used as a computational approach to the problem of finding matrix eigenvalues and eigenvectors, is in some cases an effective tool to prove the existence of the limit distribution, which is then expressed as a solution of a system of linear equations. Some examples are presented.

Authors: Kong Lingbao , Zhou Yanjun , Song Kexing , Hui David , Hu Hao , Guo Baojiang , Kang Junwei , Feng Cunli , Cao Jun
Published: March 2020

In this paper, the Cu-0.52Ag-0.22Cr alloy was prepared by hot horizontal continuous casting. The effects of aging process on micro-hardness, electrical conductivity, and nanoscale precipitates of Cu-0.52Ag-0.22Cr alloy were studied. The electrical conductivity and micro-hardness increase significantly in the early aging time. With the extension of aging time, the electrical conductivity is basically unchanged and remains at a high level. While, the micro-hardness increases slowly, the change trend is different at 623 K, 723 K, and 773 K. The optimisation of process parameters occurs in 723 K for 2 h. At this time, the electric conductivity is 95.8% IACS and the hardness is 104.1 HV0.1. The XRD result shows that the Ag and Cr are precipitated in elemental form copper matrix. Further TEM shows that, Cr exists at the sub-boundary in the form of larger nanoscale precipitates (100-200 nm). While a large number of Ag nanoscale precipitates (8-10 nm) is dispersed on the copper matrix. The synergistic effect of Ag and Cr nanoscale precipitates significantly improved the properties of the alloy.

Efficacy and Effectiveness of the PCV-10 and PCV-13 Vaccines Against Invasive Pneumococcal Disease
Authors: Berman-Rosa Melissa , O’Donnell Shauna , Barker Mackenzie , Quach Caroline
Published: March 2020

CONTEXT:

Pneumococcal conjugate vaccines (PCVs) (pneumococcal 13-valent conjugate vaccine [PCV-13] and pneumococcal 10-valent conjugate vaccine [PCV-10]) are available for prevention of pneumococcal infections in children.

OBJECTIVE:

To determine the vaccine effectiveness (VE) of PCV-13 and PCV-10 in preventing invasive pneumococcal disease (IPD) and acute otitis media (AOM) in children <5 years.

DATA SOURCES:

Systematic searches of Medline, Embase, Cumulative Index to Nursing and Allied Health Literature, Web of Science, and Cochrane.

STUDY SELECTION:

Eligible studies examined the direct effectiveness and/or efficacy of PCV-10 and PCV-13 in reducing the incidence of disease in healthy children <5 years.

DATA EXTRACTION:

Two reviewers independently conducted data extraction and methodologic quality assessment.

RESULTS:

Significant effectiveness against vaccine-type IPD in children ≤5 years was reported for ≥1 dose of PCV-13 in the 3 + 1 (86%–96%) and 2 + 1 schedule (67.2%–86%) and for PCV-10 for the 3 + 1 (72.8%–100%) and 2 + 1 schedules (92%–97%). In children <12 months of age, PCV-13 VE against serotype 19A post–primary series was significant for the 3 + 1 but not the 2 + 1 schedule. PCV-10 crossprotection against 19A was significant in children ≤5 years with ≥1 dose (82.2% and 71%). The majority of studies did not find either PCV to be effective against serotype-3. PCV-13 was effective against AOM (86%; 95% confidence interval [CI]: 61 to 94). PCV-10 was effective against clinically defined (26.9%; 95% CI: 5.9 to 43.3) and bacteriologically confirmed AOM (43.3%; 95% CI: 1.7 to 67.3).

LIMITATIONS:

Because of the large heterogeneity in studies, a meta-analysis for pooled estimates was not done.

CONCLUSIONS:

Both PCVs afford protection against pneumococcal infections, with PCV-10 protecting against 19A IPD, but this VE has not been verified in the youngest age groups.
GONAD DEVELOPMENT OF SANDFISH (Holothuria scabra) FED WITH VITAMIN E-SUPPLEMENTED DIET
Authors: Sembiring Sari Budi Moria , Hutapea Jhon Harianto
Published: March 2020

The experiment was conducted to evaluate the effect of vitamin E on the gonad development of sandfish, Holothuria scabra. Four experimental diets were formulated to contain different levels of vitamin E, i.e. 0, 150, 300, and 450 mg/kg diet. Dry diets were prepared at the same protein level (14%). The experiment was arranged in a completely randomized design with four treatments and three replicates. Before the experiment started, the internal organs of broodstock were removed (evisceration) by injecting KCl 1 N reagent into their body, and the gonads were observed to determine the sex of each broodstock. Mean total length and body weight of broodstock after the internal organ removal were 10.95 ± 0.37 cm and 61.12 ± 2.28 g, respectively. Three broodstock (one male and two females) were allocated into each plastic bucket with a volume of 150 L. Each plastic bucket was equipped with aeration and flow-through water system. Broodstock fed with experimental diet once daily at 3% of total biomass for 90 days. The results showed that vitamin E has significant effects on percentage of gonad maturation stages and gonad somatic index (GSI) (P<0.05). Vitamin E at 300 mg/kg diet was the best for gonad maturation of sandfish broodstock. Furthermore, 55.5% and 11.1% of broodstock fed a diet containing 300 mg vitamin E/kg diet reached gonad maturity stage-III and stage-IV, respectively, with GSI of 12.21%.

Authors: Rukisah Rukisah , Maulianawati Diana , Cahyadi Jimmy
Published: March 2020

Disease infection is one of the limiting factors that affect productivity in aquaculture and has caused economic losses. Luminescent vibrios and motile aeromonas septicemia (MAS) are diseases caused by Vibrio harveyi and Aeromonas hydrophila bacteria, respectively. Certain plants have antimicrobial compounds and can potentially be used to treat the diseases, such as Centella asiatica. In the present study, the crude leaves extracts of C. asiatica were examined for its antibacterial potential using methanol solvents against V. harveyi and A. hydrophila bacteria. Different concentrations of 50 mg/mL and 100 mg/mL were checked for its antibacterial activity. The crude extract was also tested for phytochemistry content and LC50 using Brine Shrimp Lethal Assay. The crude extracts of C. asiatica showed a remarkable antibacterial activity with inhibition zone of 10.57 mm against A. hydrophila and 21.14 mm against V. harveyi. The phytochemistry test result showed that C. asiatica leaves contain alkaloid, phenol, and tannin compounds. The acute lethal concentration (LC50) of C. asiatica after 24 hours exposure to the extract mixture was 254 mg/L. The results confirmed the potential use of C. asiatica extracts as a source of antibacterial compounds.
Theoretical and experimental analysis of the exact receptance function of a clamped-clamped beam with concentrated masses
Authors: Khoa Nguyen Viet , Thao Dao Thi Bich
Published: March 2020

This paper establishes the exact receptance function of a clamped-clamped beam carrying concentrated masses. The derivation of exact receptance and the numerical simulations are provided. The proposed receptance function can be used as a convenient tool for predicting the dynamic response at arbitrary point of the beam acted by a harmonic force applied at arbitrary point. The influence of the concentrated masses on the receptance is investigated. The numerical simulations show that peak in the receptance will decrease when there is a mass located close to that peak position. The numerical results have been compared to the experimental results to justify the theory.

Published: March 2020

Background: Dorsal decompressive-stabilizing techniques laminotomy with laminoplasty (LP) and laminectomy with instrumental fixation (LF) are effective methods for surgical treatment of patients with multi-level degenerative diseases of the cervical spine. At the same time, there is currently no priority in determining the optimal method for posterior decompression and stabilization.
Aim: conduct a comparative analysis of intraoperative parameters, clinical outcomes, radiological results and complications of LP and LF in the treatment of patients with multilevel degenerative diseases of the cervical spine.
Methods: A meta-analysis of prospective cohort clinical trials was carried out, the primary sources were searched using the databases PubMed, CNKI, eLibrary and the Cochrane Library, published until March 2019, which compared the results of applying the LP and LF methods in the treatment of patients with multilevel degenerative diseases of the cervical spine. For dichotomous variables, the relative risk and the 95% confidence interval were calculated; in turn, for the continuous variables, the standardized difference of the mean values and their 95% confidence intervals were used, using random effect models and a fixed effect.
Resuts: The meta-analysis included 6 prospective clinical trials, one of which was a randomized controlled trial. In total, the results of surgical treatment of 493 patients with multilevel degenerative diseases of the cervical spine were evaluated. In the group of drugs, statistically significantly smaller parameters of the duration of surgical intervention were verified (p 0.00001). At the same time, comparable parameters of cervical lordosis after surgery, the level of pain in the cervical spine, functional status according to NDI and JOA after surgery, the frequency of perioperative complications (p = 0.17, p = 0.05, p = 0.94, p = 0.96, p = 0.24, respectively).
Conclusions: A meta-analysis showed that the functional outcomes of LP and LF, as well as instrumental results in the treatment of multilevel degenerative diseases of the cervical spine, are not clinically significant. In this case, the LP technique can be performed in a shorter period of time compared with LF.

Authors: Williams Sarah , Clark Shannon , Humiston Sharon , Pahud Barbara , Middleton Donald , Lewis Kadriye
Published: March 2020

This article was migrated. The article was not marked as recommended. Background: Vaccine education during residency is not standardized. Little is known about resident perspectives on vaccines and ideal vaccine training. Methods: A convenience sample of pediatric and family medicine (FM) residents were surveyed using a de novo 22 question survey to understand perspectives on vaccines and current and preferred vaccine education curriculum. Responses were analyzed categorically and compared by resident year using Fisher's Exact test. Results: In October 2016, 126 residents from 9 pediatric and FM programs completed the survey. Resident respondents' training levels varied. Most were 25-29 years old and female. High familiarity with vaccines and agreeing to defer recommended vaccine(s) increased with additional years of training (p<0.01). Most residents want to learn more about vaccine risks, benefits, and communication skills. Preferred training modalities were in-person lectures, online modules, and continuity clinic didactics. Residents rated MMR and Hib vaccines as "highly important" more frequently than they did so for HPV and influenza vaccines. One fifth of respondents reported some degree of hesitancy regarding vaccines. Conclusion: Results provide insight on framework and scope for development of a vaccine education curriculum. Identification of vaccine hesitancy among residents and the rating of certain recommended vaccines as of variable importance underscores the need for resident vaccine training.
Stick–slip behaviour of mortar–rock interface under high loading rate
Authors: Wang Haitao , Sun Haoyu , He Yong , Su Peng
Published: March 2020

A modified push-out method was used to explore the bond characteristics of the mortar–rock interface in an anchor system at different loading rates. Under a high loading rate (≥ 1·12 × 10−4 s−1), stick–slip behaviour, which is usually used to describe the mechanism of earthquakes, was observed at the mortar–rock interface for the first time in this experimental research. The test results showed that the load–displacement curve under a high loading rate included four stages: elastic deformation, interface softening, residual friction and stick–slip oscillation. A micro-mechanical model of bond–slip at the mortar–rock interface was also developed. A series derivation revealed the relationships among the dilatancy stress of the mortar–rock interface, the loading rate and the stress drop of stick–slip. The mechanism of stick–slip behaviour at the mortar–rock interface was theoretically established. The modified visco-elastoplastic constitutive model established to describe the stick–slip characteristics of a mortar–rock interface was verified with experimental results using Abaqus software.

Authors: Stepanova Marina , Nefedyev Anton
Published: March 2020

Investment insurance products offered in insurance markets provide access to new investment tools with use of the current technologies of financial engineering. They are built in accordance with the existing standards that protect the rights of customers to receive a quality product, combining insurance protection and possibility of obtaining an investment income in terms of the integral financial decision. At the same time, the Russian insurance market presents only analogs of full-fledged investment-insurance products acting abroad. They provide functional conveniences, but they are not always as effective as other financial decisions. There exist analog investment strategies that can be formed in terms of basic parameters of investment life insurance and, at the same time, provide the investor with a more attractive return. The article presents the variants of such strategies developed by using the proposed elements of their design and presents the corresponding calculations confirming low financial attractiveness of investment life insurance for a potential investor that has taken shape at present.

Uyumluluk; kazanımlar, öğretim ve değerlendirme arasındaki örtüşmenin derecesine karşılık gelmektedir. Program uyumluluğu öğrenci başarısını artıran en önemli etkenlerden biri olmasına rağmen alan yazında bu kavramla ilgili az sayıda çalışma yer almaktadır. Bu boşluktan yola çıkarak bu çalışmada ortaokul matematik öğretmenlerinin çözümlü örneklerinin ve yazılı sınav sorularının öğretim programında yer alan kazanımlarla uyum düzeyini belirlemek amaçlanmıştır. Araştırmada iç içe geçmiş çoklu durum deseni kullanılmıştır ve katılımcılar maksimum çeşitlilik örneklemesi kullanılarak belirlenmiştir. Bu çalışmanın verileri 2009 yılında yayımlanan ilköğretim matematik dersi 1–5 sınıflar öğretim programı, 6–8. sınıflar öğretim programı ve kılavuzu, birinci araştırmacı tarafından bir dönem boyunca kayıt altına alınan sınıf içi gözlemler ve öğretmenlerin yazılı sınav kâğıtları yardımıyla toplanmıştır. Veriler, karşılaştırmalı durum sentezi tekniği kullanılarak analiz edilmiştir. Araştırmanın bulguları, öğretmenlerin çözümlü örneklerinin ve yazılı sınav sorularının öğretim programında yer alan kazanımlarla uyumunun sayılar öğrenme alanı için yeterli düzeyde olduğunu göstermiştir. Öte yandan, öğretmenler; cebir, olasılık ve istatistik ve geometri öğrenme alanlarında ciddi uyumsuzluklar sergilemişlerdir. Bulgulardan yola çıkılarak, öğretmenlerin program uyumluluğu ile ilgili yeterliklerinin geliştirilmesini sağlayacak önerilerde bulunulmuştur.
KAVRAM ÖĞRETİMİ SÜRECİNİN “BİL, ANLA, YAP” BOYUTLARI BAĞLAMINDA DEĞERLENDİRİLMESİ
Authors: BOLAT Yeliz , DOLAPÇIOĞLU Sevda
Published: March 2020

Kavram
öğretimi öğrencinin bilgiyi yapılandırmasını ve “anlam oluşturmasını” sağlayan
önemli bir uygulamadır. Ancak geleneksel olarak, eğitim programı ve öğretim
tasarımları daha çok iki boyutludur ve öğrencilerin “bilme” ve
“yapabilmelerine” odaklanmıştır. Oysa, “anlama boyutu” bilginin
yapılandırılması ve üst düzey düşünme becerilerinin gelişimi için önemlidir. Bu
nedenle çalışma kavram öğretimi sürecinin Erickson (2007) tarafından sunulan
“bil, anla, yap” boyutları bağlamında öğrenci gelişimine katkısının
değerlendirilmesi amacıyla yapılmıştır. Araştırmada nitel araştırma yöntemlerinden durum çalışması
kullanılmıştır. Seçilen kavramların öğretimi 16 ders
saatinde gerçekleştirilmiştir. Çalışma Adana
ilinin merkez ilçelerinden birinde, bir devlet ilkokulunda yürütülmüştür. Çalışmaya on üçü erkek, sekizi kız olmak üzere
toplam 21 ilkokul dördüncü sınıf öğrencisi
katılmıştır. Öğrencilerdeki gelişim “düzey belirleme kontrol listeleri” ile
izlenmiştir. Sonuç olarak, kavram öğretiminin “bil,
anla, yap” boyutlarında bilgiyi yapılandırma sürecine katkı sağladığı,
ancak anlama boyutunda diğer boyutlara göre daha fazla gelişim olduğu
belirlenmiştir. Anla boyutunda; nedenini açıklama, sınıflandırma, ayırt etme,
soru sorma, özelliklerini gösterme davranışların edinmesinde katkısı olduğu
bulgusuna ulaşılmıştır.

Authors: CANBOLAT Gülcan , TOP Ercan
Published: March 2020

The aim of this study is to examine the use of threaded discussions in
the blog environment in terms of the factors affecting student course
satisfaction. Experimental and control groups were selected, and the students
in the experimental group participated in threaded discussions in the blog
environment. In the study, students in both groups were asked to share, in the
blog environment, their course materials and reports about the subjects
included in the course. The experimental group was asked to participate in
asynchronous threaded discussions, and feedback about the quality of their
participation was rapidly provided by the researchers. The data, collected
before and after the experiment, were distributed online. According to the
findings, the effect of threaded discussions on students’ beliefs about blogs
and peer review was not significant, and perceived learning, sense of community,
collaborative learning, and threaded discussion were the variables that
predicted course satisfaction. The students’ satisfaction scores were not
affected by their beliefs about blogs, peer review, and their ability to
organize multimedia features.

Problematical issues of mediation conducted by a barrister during reconciliation within criminal proceedings
Authors: Kovalchuk A.
Published: March 2020

It is well known that one of the hallmarks of restorative justice is the use of mediation as an effective way of resolving the dispute. The above mentioned process proved to be quite popular in the practice of domestic lawyers, which in its turn became the basis for ambiguous practice and the need for the legislator's attention. That is why motive changes are taking place in Ukraine with the purpose of legislative consolidation of the institute. However, due to the lack of detailed legislative regulation of the basic provisions of regulation of mediation, namely - the status of mediator, regulatory secrecy of non-disclosure of client secrets, bodies of quality control of the provided services, etc., there is a possibility of abuse of the mentioned institute in the territory of Ukraine.

The purpose of the article is to identify the issues that may arise in the case of the combination of lawyer and mediator roles within a single proceeding.

Based on the analysis of the legal framework of domestic and international legislation, it is necessary to outline the following problems.

It is argued that, to date, a major reason for the lack of active use of mediator services is the list of reasons which include both low level of public awareness and lack of legislative basis. That is why there is no proper attention to the problem of abuse of mediator status.
It is concluded that the conduct of mediation by a barrister within one proceeding gives grounds for the risk of violation of the basic principles of mediation, namely – confidentiality and independence. These statements are based on the definition of difference of the professions in their nature and purposes.
It is noted that a problematic issue is the fact that the lawyer-client relationship is governed by a contract for the provision of lawyer services, unlike the other party to the negotiations. This fact leads to a number of opportunities for abuse of the status of mediator and the exercise of fraudulent advocacy.
It is stated the existence of a legal conflict in case of completion of the mediation procedure without result in the form of reconciliation between the suspect and the victim. It is also outlined the possibility of manipulation of the information provided by the parties in the case of a change in the role of the barrister.
It has been determined that due to the retreat of the regulatory regulation of the mediation activity by the lawyer, there are no control bodies that could point out the quality of the lawyer's rendering of the above services.
Testimonial immunity as an element of the principle of protection of the rights and freedoms of man and citizen in criminal proceedings
Authors: Kharitonova M.
Published: March 2020

In the conditions of formation of the rule of law, one of the biggest manifestations of the democratization of law enforcement activity in Ukraine is the legislative protection of human rights, the creation of guarantees of the rights and legitimate interests of the individual. In this regard, the legal status of participants in criminal proceedings becomes especially important. In addition, the important task of criminal procedural science is to identify and eliminate gaps in the legal regulation of criminal procedural relations. In this regard, studies are currently being conducted to identify legal issues in the field of law and recommendations are being prepared on this basis.

It is known that every participant of criminal justice has its own legal status, enshrined in the rules of the Criminal Procedure Code of Ukraine. The procedural status of the victim, suspect, accused legislator and procedural scientist are given much attention, including the issues of securing their rights and legitimate interests. The procedural status of a witness in criminal proceedings requires, in our opinion, additional investigation, including through the prism of securing the rights and legitimate interests of the person in conducting pre-trial investigation and judicial proceedings in criminal proceedings. Research into the problems of the theory and practice of witness immunity is relevant, as various aspects of witness immunity are controversial among both theorists and practitioners. Of course, it is, first and foremost, important for witnesses to have additional opportunities for state defense.

The purpose of the article is to address topical issues arising from the reform of criminal procedural legislation, which has created some difficulties in law enforcement practice, including the implementation of the rules governing the institution of immunity of witnesses. In particular, this is explained by contradictory, sometimes unsuccessfully formulated provisions of the legislation itself, which are not always consistent with the implementation of the tasks of judicial reform. In addition, the article raises the problem of witness immunity classification. The authors' different perspectives on the concepts and components of witness immunity are examined. Discussion questions of the classification of the immunity of witnesses are revealed and its classification is divided into categories and categories of testimony provided by witnesses.

The result of the study is to provide valid proposals for improving the legal regulation of the institute of immunity of witnesses in criminal proceedings. Witness immunity is a set of rules that exempt certain groups of witnesses from the obligation to testify in criminal proceedings, as well as exempt a witness from testifying against themselves. In this regard, the immunity of the witness is divided into two types of imperative (absolute, unconditional) and dispositive (relative, conditional).
High-Frequency Spectral Decay Characteristics of Seismic Records of Inland Crustal Earthquakes in Japan: Evaluation of the fmax and κ Models

Published: March 2020

We examined high-frequency spectral decay characteristics of ground motions for inland crustal earthquakes in Japan, which are important in strong ground motion predictions. We examined 105 earthquakes (Mw 3.3–7.1), including seven large earthquakes (Mw 5.9–7.1). Spectral decay characteristics were accurately evaluated assuming the ω-squared source model and using two approaches: the fmax model (commonly used in Japan), described by the cutoff frequency fmax and the power coefficient of spectral decay s, and the κ model (commonly used in worldwide), the exponential spectral decay model, described by the parameter κ and the specific frequency fE at which a spectrum starts to decrease linearly with increasing frequency in log–linear space. For large earthquakes, we estimated fmax to range from 6.5 to 9.9 Hz and s from 0.78 to 1.60 in the fmax model, and κ to range from 0.014 to 0.051 s and fE from 2 to 4.5 Hz in the κ model. In both approaches, we found that the spectral decay characteristics are regionally dependent. fmax in the fmax model and fE in the κ model tended to be smaller for large earthquakes than for moderate and small earthquakes, clearly demonstrating a seismic moment dependency. We confirmed positive correlations between equivalent parameters of the two approaches, that is, between s and κ and between fmax and fE. Moreover, we found that both approaches are appropriate for evaluating spectral decay characteristics, as long as the spectral decay parameters are appropriately evaluated by comparison with observed spectra. We examined the effects of the spectral decay characteristics on strong ground motion predictions, and demonstrated that simulated motions corrected using the fmax model and those corrected using the κ model are almost the same. The results presented in this article contribute to improving predictions of high-frequency strong ground motion.
Wave Scattering of Plane P, SV, and SH Waves by a 3D Alluvial Basin in a Multilayered Half-Space

Published: March 2020

A special indirect boundary element method (IBEM) is proposed to investigate the waves scattering of plane P, SV, and SH waves by a 3D alluvial basin embedded in a multilayered half-space. The new IBEM, which uses half-space Green’s functions for uniformly distributed loads acting on an inclined plane as its fundamental solutions, has the merits of (1) excellent capability of dealing with the stratification of the basin and the external half-space, (2) without the problem of singularity due to fictitious distributed loads being directly applied on the real boundaries, and (3) good adaptability to complex models with trapezoidal or triangular elements being used to discretize the boundaries. The validity and accuracy of the new method are verified by comparing its results with those in the literature. To illustrate the general applicability and efficiency of the new method further, 3D alluvial basins of varying shapes, depths, and sedimentary sequences embedded in a single layer overlying a homogeneous half-space are numerically studied. Numerical results show that the basin’s shape, depth, and sedimentary sequence all have significant impact on the ground seismic responses; the incident angle also has noticeable effects on the surface motion, and these effects are more prominent at the observation points along the incident direction of the plane waves; for the case of layered model, the displacement spectral amplification is affected by the eigenmodes of the vibrations of the layers, both inside and outside the basin.
Estimation of Wavelet Coherence of Seismic Ground Motions

Published: March 2020

The relation between the nonstationary seismic ground motions at two sites is often characterized using lagged coherence and phase spectrum. Their evaluation is most often carried out using ordinary Fourier analysis (i.e., without windowing) by assuming that they are time invariant. In the present study, the assessment of time-varying coherence is carried out based on the auto- and cross-wavelet power spectrum. The coherence is expressed in terms of lagged wavelet coherence and wavelet phase spectrum. For the analysis, the generalized Morse wavelets are employed, and the ground-motion records for several events from dense arrays located in Taiwan are used. It was shown that without adequate smoothing in scale and time, the obtained lagged wavelet coherence varies drastically in time and frequency (i.e., scale). A parametric analysis shows that the estimated coherence is sensitive to the degree of smoothing. The results of the lagged wavelet coherence and wavelet phase spectrum are time varying and frequency varying. This is in contrast with the time-invariant lagged coherence and phase spectrum assumed for the amplitude modulated evolutionary stochastic process. It is inferred from the results that the use of a time-varying coherence should be considered for seismic ground motions modeled as nonstationary processes.
Rainfall-Induced Variation of Seismic Waves Velocity in Soil and Implications for Soil Response: What the ARGONET (Cephalonia, Greece) Vertical Array Data Reveal
Authors: Roumelioti Zafeiria , Hollender Fabrice , Guéguen Philippe
Published: March 2020

We apply interferometry by deconvolution to compute the shear-wave velocity in shallow sediments (0–83.4 m) based on earthquake records from a vertical accelerometric array (ARGOstoli Network [ARGONET]) on Cephalonia Island, Greece. Analysis of the time variation of measured values reveals a cyclical pattern, which correlates negatively to rainfall and a soil moisture proxy. The pattern includes a sharp reduction in velocity at the beginning of rainy seasons and a gradual rise toward dry periods, the overall variation being around 20%–25% within the shallowest depth interval examined (0–5.6 m) and estimated to reach 40% within the top 2 m. The variation itself and its amplitude are verified by surface-wave dispersion analysis, using ambient vibration data. Synthetic standard spectral ratios suggest that this seasonal effect leaves an imprint on soil response, causing differences in the level of high-frequency ground motion between dry and rainy seasons, and this is verified by earthquake records. Furthermore, the near-surface velocity decrease due to soil saturation can be of the same order of magnitude as the nonlinear coseismic variation, masking the physical process of the nonlinear response of the site due to weak-to-strong-motion shaking. Thus, seasonal variations of seismic-wave velocities in shallow sediments may be important for a number of site-effect related topics, such as high-frequency ground-motion variability, soil anisotropy, kappa measurements, nonlinear site response, and so on.
