An improved seismic data completion algorithm using low-rank tensor optimization: Cost reduction and optimal data orientation
Authors: Popa Jonathan , Minkoff Susan E. , Lou Yifei
Published: February 2021

Seismic data are often incomplete due to equipment malfunction, limited source and receiver placement at near and far offsets, and missing crossline data. Seismic data contain redundancies because they are repeatedly recorded over the same or adjacent subsurface regions, causing the data to have a low-rank structure. To recover missing data, one can organize the data into a multidimensional array or tensor and apply a tensor completion method. We can increase the effectiveness and efficiency of low-rank data reconstruction based on tensor singular value decomposition (tSVD) by analyzing the effect of tensor orientation and exploiting the conjugate symmetry of the multidimensional Fourier transform. In fact, these results can be generalized to any order tensor. Relating the singular values of the tSVD to those of a matrix leads to a simplified analysis, revealing that the most square orientation gives the best data structure for low-rank reconstruction. After the first step of the tSVD, a multidimensional Fourier transform, frontal slices of the tensor form conjugate pairs. For each pair, a singular value decomposition can be replaced with a much cheaper conjugate calculation, allowing for faster computation of the tSVD. Using conjugate symmetry in our improved tSVD algorithm reduces the runtime of the inner loop by 35%–50%. We consider synthetic and real seismic data sets from the Viking Graben Region and the Northwest Shelf of Australia arranged as high-dimensional tensors. We compare the tSVD-based reconstruction with traditional methods, projection onto convex sets and multichannel singular spectrum analysis, and we see that the tSVD-based method gives similar or better accuracy and is more efficient, converging with runtimes that are an order of magnitude faster than the traditional methods. In addition, we verify that the most square orientation improves recovery for these examples by 10%–20% compared with the other orientations.
Accelerating least-squares Kirchhoff time migration using beam methodology
Authors: Yue Yubo , Liu Yujin , Gray Samuel H.
Published: February 2021

Least-squares migration is an advanced imaging technique capable of producing images with improved spatial resolution, balanced illumination, and reduced migration artifacts; however, the prohibitive computational cost poses a great challenge for its practical application. We have incorporated the beam methodology into the implementation of Kirchhoff time modeling/migration and developed a fast common-offset least-squares Kirchhoff beam time migration (LSKBTM). Different from conventional Kirchhoff time modeling/migration in which the seismic data are modeled/migrated trace by trace, the mapping operation in Kirchhoff beam time modeling/migration is performed in terms of beam components and is performed only at sparsely sampled beam centers. Therefore, the computational cost of LSKBTM is significantly reduced in comparison with that of least-squares Kirchhoff time migration (LSKTM). In addition, based on the second-order Taylor expansion of the diffraction traveltime, we introduce a quadratic correction term into the inverse/forward local slant stacking, effectively enhancing the computational accuracy of LSKBTM. We used 2D synthetic and 3D field data examples to verify the effectiveness of our method. Our results indicate that LSKBTM can produce images comparable with those of LSKTM, but at considerably reduced computational cost.
A seismic structural overview of Liard Basin, Northeast British Columbia, Canada
Authors: Leslie-Panek Jennifer , McMechan Margot
Published: February 2021

The Liard Basin is an important subbasin of the Western Canada Sedimentary Basin located in Northeast British Columbia along the eastern margin of the Canadian Cordillera. It contains significant potential unconventional gas resources but is largely underrepresented in public literature. Using available-for-purchase 2D seismic data, a regional structural interpretation of the basin was completed providing the first seismically controlled, high-level overview of the structural features of the basin and its surrounding area. The shape of the Liard Basin largely reflects the orientation of older Paleozoic and Proterozoic extensional structures that localized structures formed during Cretaceous-Tertiary compressive deformation. The eastern boundary of the basin is marked by the well-documented Bovie Structure. The Liard Anticline and the Liard River Anticline found near 60°N latitude are the only large structures located within the Liard Basin proper. Inversion of the herein named Liard Basin Boundary Structure, a west-side-down fault zone of Early Paleozoic age, localized the northwest boundary of the basin with the Liard Fold and Thrust Belt. A triangle zone bounds the Rocky Mountain Foothills and the Liard Basin to the southwest. Reflectors in the Proterozoic strata below the Liard Basin were deformed by compressive and then extensional structures prior to the deposition of Paleozoic strata. Proterozoic strata are involved in all of the major structures of the adjacent Liard Fold and Thrust Belt, the Rocky Mountain Foothills, and the Bovie Structure. These structures controlled the location of the Liard Basin.
Determining fast-S and slow-S propagation directions with SV-P data produced by buried explosives and recorded with vertical geophones

Published: February 2021

We have evaluated the concept of practicing S-wave reflection seismology with legacy 3D seismic data generated by a P-wave source and recorded with only vertical geophones. This type of S-wave imaging is based on the principle that seismic P-wave sources not only produce a downgoing illuminating P wavefield, but they also simultaneously produce a downgoing illuminating SV wavefield that, in almost all cases, is suitable for S-wave reflection imaging. The S-mode used in this study is the SV-P, or converted-P, mode. This mode involves a downgoing illuminating SV wavefield and an upgoing reflected P-mode that is recorded by vertical geophones. In flat-layered stratigraphy, the lengths of the SV and P raypaths in SV-P imaging are identical to the lengths of the SV and P raypaths in P-SV imaging with P-sources and 3C geophones. P-SV imaging of deep rocks has been practiced for more than two decades; SV-P imaging is a new concept. SV-P data should provide the same options for investigating deep rocks as do P-SV data. We have determined one of the equivalences between SV-P data extracted from vertical-geophone data and P-SV data extracted from horizontal geophones: that both modes react to azimuth-dependent variations in the S velocity in anisotropic rocks. Azimuthal variations in the SV-P traveltime can be used to define the polarization direction of the fast-S-wave mode, which is also the azimuth of the maximum horizontal stress (SHmax). Our investigation demonstrates a noninvasive method for monitoring changes in the SHmax azimuth across a CO2 storage reservoir, or any targeted porous rock, as fluids are cycled into, and then out of, that rock’s pore space.

Published: February 2021

Background

The UK Biobank contains data with varying degrees of reliability and completeness for assessing depression. A third of participants completed a Mental Health Questionnaire (MHQ) containing the gold-standard Composite International Diagnostic Interview (CIDI) criteria for assessing mental health disorders.

Aims

To investigate whether multiple observations of depression from sources other than the MHQ can enhance the validity of major depressive disorder (MDD).

Method

In participants who did not complete the MHQ, we calculated the number of other depression measures endorsed, for example from hospital episode statistics and interview data. We compared cases defined this way with CIDI-defined cases for several estimates: the variance explained by polygenic risk scores (PRS), area under the curve attributable to PRS, single nucleotide polymorphisms (SNPs)-based heritability and genetic correlations with summary statistics from the Psychiatric Genomics Consortium MDD genome-wide association study.

Results

The strength of the genetic contribution increased with the number of measures endorsed. For example, SNP-based heritability increased from 7% in participants who endorsed only one measure of depression, to 21% in those who endorsed four or five measures of depression. The strength of the genetic contribution to cases defined by at least two measures approximated that for CIDI-defined cases. Most genetic correlations between UK Biobank and the Psychiatric Genomics Consortium MDD study exceeded 0.7, but there was variability between pairwise comparisons.

Conclusions

Multiple measures of depression can serve as a reliable approximation for case status where the CIDI measure is not available, indicating sample size can be optimised using the entire suite of UK Biobank data.
Explainable Tree-Based Predictions for Unplanned 30-Day Readmission of Patients With Cancer Using Clinical Embeddings
Authors: Wong Chi Wah , Chen Chen , Rossi Lorenzo A. , Abila Monga , Munu Janet , Nakamura Ryotaro , Eftekhari Zahra
Published: February 2021

PURPOSE

Thirty-day unplanned readmission is one of the key components in measuring quality in patient care. Risk of readmission in oncology patients may be associated with a wide variety of specific factors including laboratory results and diagnoses, and it is hard to include all such features using traditional approaches such as one-hot encoding in predictive models.

METHODS

We used clinical embeddings to represent complex medical concepts in lower dimensional spaces. For predictive modeling, we used gradient-boosted trees and adopted the shapley additive explanation framework to offer consistent individualized predictions. We used retrospective inpatient data between 2013 and 2018 with temporal split for training and testing.

RESULTS

Our best performing model predicting readmission at discharge using clinical embeddings showed a testing area under receiver operating characteristic curve of 0.78 (95% CI, 0.77 to 0.80). Use of clinical embeddings led to up to 23.1% gain in area under precision-recall curve and 6% in area under receiver operating characteristic curve. Hematology models had more performance gain over surgery and medical oncology. Our study was the first to develop (1) explainable predictive models for the hematology population and (2) dynamic models to keep track of readmission risk throughout the duration of patient visit.

CONCLUSION

To our knowledge, our study was the first to develop (1) explainable predictive models for the hematology population and (2) dynamic models to keep track of readmission risk throughout the duration of patient visit.
Worldviews of science teachers in educational-technological context as a key factor in digitalization of teaching practices
Authors: Tsybulsky Dina , Muchnik-Rozanov Yulia
Published: February 2021

Background:This research deals with science teachers' worldviews in the educational-technological context. Obtaining a deeper insight into teachers' discourse regarding school digitalization and understanding teachers' worldviews in the educational-technological context may be viewed as crucially important since the latter tends to play a central role in the process of digitalization of teaching practices.

Methods:This study addresses the following questions: (1) Was there a difference between the teachers regarding their foci of attention expressed via personal pronouns? (2) Was there a difference between the teachers in terms of the quality and degree of their emotional immersion in the discussed topic expressed through the use of emotion words? (3) What are the semantic fields of the word clusters that include the lexemes technology and digital, and do they implicitly convey differences in teachers' understanding of school digitalization? The data were extracted by means of in-depth interviews with 38 Israeli science teachers. The linguistic analysis was employed to examine teachers' language behavior.

Results:The results point out the differences in teachers' worldviews, manifested through language behavior. In particular, the differences between the three groups of teachers (outside observers, circumspect participants, and conscientious participants) were found regarding their foci of attention, the level of emotional immersion, and their implicitly conveyed understanding of the digitalization of teaching practices.

Conclusions:The teachers' worldviews are the key element for understanding what it means to be or not to be a teacher in a digital society. In addition, our study demonstrates that linguistic analysis in educational research is a promising methodological approach that can render an in-depth and comprehensive picture of the explored phenomenon.
La Educación de las Personas Adultas en los Cincuenta Años de Historia Democrática en España.
Authors: Rumbo Arcas Begoña
Published: February 2021

The historical period in question is key for the Spanish political life and, consequently, for the educational policy of adult education. Thanks to its purpose of making the person literate, adult education is no longer at the service of any interest of the Franco regime and it is considered an education to compensate educational inequalities. The dream of freedom, which come with the first years of democracy, had its influence on education, recognizing the right that adults also must be educated. In almost 50 years of democracy, the alternation in power of the PSOE and the PP parties has produced a prolific national regulatory framework that is not without political and ideological disagreements. Also, Spain’s entry into the European Union directs the educational policies of our current educational system, influencing the way to address adult education affecting from transnational and cross-sector parameters, that seek efficiency and quality to be internationally competitive. The purpose of this article is to analyze the changes in the policies that govern the adult education in Spain and the conceptual consequences and practical implications derived in these fifty years of democracy.
Altivez e resistência na representação do Outro em Dulce Sudor Amargo de Miguel Rio Branco
Authors: Castanheira Rafael
Published: February 2021

Este artigo tem como objetivo analisar algumas fotografias de Miguel Rio Branco que, diferente de muitos de seus predecessores que atuaram na documentação de determinados grupos sociais no Brasil, buscou romper com a representação do Outro segundo uma visão externa, estereotipada e unívoca. Ao documentar grupos marcadamente oprimidos como prostituas e moradores de ruas, ele produziu não apenas imagens libertas do olhar romântico predominante entre fotógrafos viajantes que percorreram o território brasileiro a partir da segunda metade do século XIX, mas, sobretudo, narrativas visuais que transcendem a função exclusivamente informativa e, por vezes, denuncista das fotografias dos dramas sociais do país realizadas em meados do século XX por fotojornalistas nacionais ou estrangeiros.
O cinema como cosmopoética do pensamento decolonial
Authors: Andrade Catarina Amorim de Oliveira , Brito Alves Álvaro Renan José de
Published: February 2021

Neste artigo pretendemos compreender se, e de que forma, o cinema pode servir a uma cosmopoética do pensamento decolonial. Para tanto, nos apoiaremos em alguns conceitos dos estudos decoloniais, que buscam atualizar a tradição crítica do pensamento latino-americano a partir da problematização do pensamento hegemônico (eurocêntrico), oferecendo novas releituras histórias e novas possibilidades de produção dos saberes. A perspectiva decolonial opera fornecendo novos horizontes para o pensamento, promovendo uma ecologia dos modos de saber e conhecimento não reconhecidos pelas epistemologias dominantes. Assim, buscamos entender a potência cosmopoética do cinema e como ele pode contribuir, dentro dos espaços de educação, como alternativa epistemológica para o pensamento decolonial.

Published: February 2021

O Programa Agrinho, concebido em 1995, defende uma educação crítica, criativa e reflexiva a fim de que os docentes e os discentes adquiram autonomia, tornando-se pesquisadores e produtores de novos conhecimentos. O referido programa oferta cursos de formação permanente a professores com o objetivo de incentivá-los à pesquisa por meio de uma proposta pedagógica baseada no pensamento complexo. Os cursos de formação permanente na modalidade de educação a distância (EAD), porém, consolidaram-se somente em 2012 e desde então vêm preparando os docentes para questões ambientais, bem como para temas de relevância social da contemporaneidade. Por conseguinte, esta pesquisa tem o objetivo de analisar como os princípios do pensamento complexo se fazem presentes nos cursos de formação permanente ofertados pelo Programa Agrinho, na modalidade de EAD, a professores tanto da rede pública como privada. Este trabalho classifica-se como um estudo de caso descritivo com abordagem qualitativa, uma vez que os dados foram coletados a partir de experiências obtidas por intermédio de diferentes cursos fornecidos pelo Programa Agrinho na modalidade de EAD, que visam à formação permanente de professores pesquisadores, críticos, reflexivos e atentos às temáticas ambientais por meio das estratégias pedagógicas de Aprendizagem Colaborativa e de Cartografia Cognitiva, que incentivam a colaboração e a construção de Mapas Conceituais.
AS MÍDIAS DIGITAIS NO CONTEXTO DA SOCIEDADE CONTEMPORÂNEA: INFLUÊNCIAS NA EDUCAÇÃO ESCOLAR
Authors: Peixoto Reginaldo , Oliveira Eloisa Elena de Moura Santos
Published: February 2021

O objetivo deste texto é apresentar uma discussão sobre os caminhos percorridos pelas tecnologias da informação e comunicação – TIC e sua influência na sociedade e na educação, ainda que de forma bastante breve. Assim, por meio da pesquisa bibliográfica, tomaremos as mídias digitais como ferramentas influenciadoras de mudanças nos modos de viver ao longo dos tempos e, principalmente, na atualidade, uma vez que elas estão presentes em muitos espaços de atividades humanas, inclusive, no dia a dia da escola e no trabalho que desenvolvem os docentes. A educação, por ser mutável, pode contribuir para uma maior inclusão dos sujeitos escolares no mundo das tecnologias, propiciando ambientes de aprendizagens colaborativas entre alunos e professores. Por isso, defendemos que os processos escolares, além de propiciar vivências dos educandos com as ferramentas tecnológicas, vislumbrem também a formação continuada dos seus profissionais, pois a escola, enquanto espaço de representação da sociedade, precisa, na medida do possível, se aproximar de suas práticas.

Published: February 2021

Resumo: Um corpo que se move diz sobre o que sente. Esta pesquisa quer mostrar a importância de se estar atento aos corpos das crianças, para sermos capazes de construir de forma coletiva uma relação positiva ou bom encontro. Estar aberto para perceber o que diz o corpo de uma criança ao se mover e entender que ela também é capaz de sentir o que o nosso corpo adulto expressa, traz para a consciência o fato de que os corpos dialogam de acordo com a simbologia de seus movimentos. Estar em uma relação de aprendizagem de corpo inteiro é acreditar que a qualidade dos vínculos que criamos com as crianças hoje, será a base dos vínculos que elas criarão no futuro.

Este texto busca pensar as produções culturais do cotidiano como práticas de significação de sujeitos trans-parentes (praticantes de imagens e sons nas margens), em processos de negociação com modos de (in)visibilidade a partir dos discursos da mídia. Interessa-nos as narrativas midiáticas a respeito do (des)aparecimento desses corpos precários e vulneráveis, mas também alianças possíveis (como pensadas por Judith Butler) a partir dos materiais da mídia. Se, como disse Susan Sontag, as imagens provocam, ao mesmo tempo, efeitos de engajamento e distanciamento, nossa aposta metodológica se faz através de uma interpretação dos efeitos dos acontecimentos que impedem a expansão de gestos travestis nas mídias e nossa aposta política se concentra no desejo e na implicação em contar outras histórias sobre esses gestos.

The impact of lived experience on health care workers' knowledge, attitudes and behaviour regarding mental illness
Authors: Sherring Simon
Published: February 2021

Background/Aims

The literature suggests that many health care workers hold stigmatising attitudes towards mental illness. This study aimed to ascertain information regarding the impact of lived experience on health care workers' knowledge about mental illness, attitudes towards mental illness and intended behaviours towards people who experience mental illness.

Methods

This quantitative study used a questionnaire survey of health care workers employed in four National Health Service Trusts (n=2073). Statistical analyses were conducted.

Results

Lived experience of a mental illness (self or family member) was associated with more favourable knowledge about mental illness, attitudes towards mental illness and intended behaviours towards those with a mental illness.

Conclusions

The lived experience of mental illness among health care workers could be harnessed as a resource to improve service delivery. There should be a long-term commitment to capitalising on the benefit to patient care of lived experience among health care workers.
Lecturers’ Aptitudes, Attitudes and Professional Development in Higher Education at University of Cuenca
Authors: Pacheco Guillermo , Espinoza María-Isabel , Cabrera-Arias Sandra , Cabrera-Tenecela Patricio
Published: February 2021

Continuous changes in social demand and development provide an acute and continuous pressure on universities. The question is whether higher education institutions (HEI) in Ecuador deliver graduates with the competences to provide timely economic, ecological, and sustainable solutions. Additionally, HEIs should prepare graduates to find employment in a society characterized by greater uncertainty, extensive use of information technology, speed, risk, complexity and interdisciplinary work. To face this challenge, universities need lecturers to possess a mix of aptitudes, attitudes, and professional development in teaching, research, and services. Unfortunately, knowledge is sparse about the readiness of their pupils to function effectively in a rapidly changing and increasingly globalized environment. Accordingly, this study uses an explanatory sequential mixed-methods approach to explore the impact of lecturers’ aptitudes, attitudes, and professional development on teaching and student learning at the University of Cuenca. Lecturers’ perceptions about their aptitudes and their attitudes are higher than the students’ perceptions. Faculty representatives believe that untenured lecturers have a better attitude and aptitude than the tenured lecturers. A third part of lecturers have achieved one of the required criteria in research development. Students from biological sciences are more satisfied with their lecturers and the competence development that they receive than the students from social sciences or engineering. Understanding the likely implication of the variables, aptitudes, attitudes and professional development, on the quality of teaching and learning is fundamental for the design and carrying out of educational reforms.

Published: February 2021

Abstract. Bareke T, Addi A. 2019. Bee flora resources and honey production calendar of Gera Forest in Ethiopia. Asian J For 3: 69-74. Gera forest contains substantial coverage of natural forest and known as a Key Biodiversity Hotspot area for Coffea arabica conservation and one of the potential areas for beekeeping. The study was carried out to assess the bee flora and flowering calendar to harvest more honey following the flowering plant cycle. Semi-structured questionnaires, participatory Rural Appraisal (PRA) techniques, and field observation were used for data collection. Honey samples collection was also made to identify the botanical origin of honey through honey pollen analysis. Seventy-four bee plant species were identified, which belongs to 41 families. Among the identified plant families, Asteraceae (29.3%), Lamiaceae (14.6%), Acanthaceae (12.2%), and Fabaceae (9.8%) are the most frequent families, represented by the highest species composition in the area. Four major honey harvesting durations were identified (January, March, April, and early June for Vernonia, Coffee, Schefflera, and Croton honey respectively) using the flowering calendar in Gera Forest. The pollen analysis of honey revealed that four types of monofloral honeys were identified comprising Schefflera abyssinica, Vernonia amygdalina, C. arabica and Croton macrostachyus in Gera forest. This is due to their abundance and potentiality for honey production. Therefore, the beekeepers should follow the flowering calendar of the plant to exploit the potential of the forest for honey production. Furthermore, market promotion for monofloral honeys of the Gera forest should be made as an incentive for the beekeepers to sell honey with premium prices and branding and labeling of honey of the area

Tegegne S, Workineh B. 2017. Vegetative structure, floristic composition and natural regeneration of a species in Ylat Forest in Meket Woreda, Northeastern Ethiopia. Asian J For 1: 40-53. The natural forest of Ylat in Meket Woreda, Northeastern Ethiopia was examined to decide the vegetative structure, floristic formation and natural regeneration of woodland species and to supply data on sustainable administration of the woody plants in specific and the woodland founts in common. Systematic sampling design was used in this study to gather vegetation information. For each of the sampling sites, five transect lines having fiftyfour primary plots with 400 m2 (20m × 20m) each were laid out to gather the information on woody species along 200m line transects. A total of 60 vascular plant species having a place to 41 families and 56 genera were identified of which 13 (21.67%) were trees, 31 (51.67%) bushes, 6 (10%) climbers and 10 species (16.66) of herbs. Of all the families, Lamiaceae (8.33%) and Fabaceae, Rosaceae, Solanaceae and Euphorbiaceae 3 species (5%) were the most overwhelming woody plant species and followed by Sapindaceae, Aloaceae, Ranunclaceae, Poaceae, Oleaceae, Polygonaceae and Cucurbitaceae contains 2 species each (3.33%). A total of 2652 woody plant species individuals (1227.77 individual/ha) were found of which 405 individuals were Myrsine africana and 19 individuals were Millettia ferruginea and 20 individuals were Dombeya torrida. This data showed the highest and the lowest number of woody plant species. The thickness of woody species with DBH ≥ 2.5cm was 1227.77 individual/ha, basal zone was 1 m2 /ha, frequency of woody species was 258. The overall Shannon diversity and evenness of woody species was 2.94 and 0.84 respectively, demonstrating that the diversity and evenness of woody species within the timberland is moderately high. The woody plant species having the highest importance value index (IVI) were Erica arborea (36.31) followed by Allophylus abyssinicus (28.65) whereas Hagenia abyssinica, Myrica salicifolia, Euphorbia tirucalli, Calpurnia aurea were the lowest IVI and should be given conservation priority. Finally, this study showed that the population structure of the most woody plant species in Ylat Timberland was in a great state of regeneration recruitment level.

Abstract. Mahdiyanti SH, Tsuchikawa S, Mitsui K, Tolvaj L. 2020. Steaming-caused chemical changes of sugi (Cryptomeria japonica) wood monitored by NIR spectroscopy. Asian J For 4: 7-10. Sugi (Cryptomeria japonica D. Don) wood samples were steamed, applying a broad range of steaming time (0-20 days) at 90 and 110°C steaming temperatures. NIR spectroscopy was used to monitor the chemical changes caused by steaming. The difference spectrum method was applied to find the absorption increases and decreases. Before the subtraction, the spectra were normalized to one unit at 1739 nm to eliminate the parallel shift of the spectra. Steam-induced chemical changes in the wavelength range of 1300-2100 nm are related to the absorption of water and the absorption of extractives, especially phenolic contents. These chemical changes are suspected to be strongly related to color changes in steamed wood. Longer duration of steaming caused phenolic compounds to change into similar contents in all wood tissues, which cause their color to change more uniformly. Steaming caused a water bounding capacity loss of the cell wall. This change was much faster at 110°C than at 90°C.

Abstract. Tjong DH, Sari RM, Roesma DI. 2020. Morphological variation of plantain squirrel Callosciurus notatus (Boddaert, 1785) (Rodentia: Sciuridae) population in West Sumatra, Indonesia. Asian J For 21: 54-60. A study about the morphological variation of plantain squirrel among several populations in West Sumatra has been done in West Sumatra. There were 38 specimens of C. notatus collected from Padang, Lubuk Basung, Sangir, and Baso by using a survey and direct collection method. The morphometric measurement was conducted in the Laboratory of Genetic and Biomolecular, Department of Biology, Faculty of Mathematics and Natural Sciences, Andalas University. Morphological measurement data based on 21 external characters and 35 skull characters were analyzed by the Kruskall Wallis test, Principal Component Analysis (PCA), and Unweighted Pair Group Method Arithmetic Average (UPGMA). The result showed that there was morphological variation in ten body characters and nine skull characters. It is necessary to do further research to determine what environmental factors specifically influence certain morphological characters.

Abstract. Hossen S, Hossain MK, Hossain MA, Uddin MF. 2020. Quantitative assessment of tree species diversity of Himchari National Park (HNP) in Cox’s Bazar, Bangladesh. Asian J For 5: 1-7. The aim of the study was to assess the tree species composition, dominance, and quantitative distribution of tree species of Himchari National Park, Cox’s Bazar in Bangladesh through stratified random sampling method using sample plots (51) of 20 m x 20 m in size during the period of January 2017 to May 2018. A total of 961 stems (dbh ≥ 5 cm) of 88 tree species belonging to 64 genera and 37 families were enumerated where the stem density and basal area were 457.39 stem ha-1 and 10.979 m2 ha-1 respectively. On the other hand, the species diversity index, Shannon-Wiener’s diversity index, Shannon’s maximum diversity index, species evenness index, Margalef’s diversity index, and Simpson’s diversity index were 0.092, 3.733 ± 0.0071, 4.477, 0.834, 12.667 and 0.039 ± 0.0003 respectively. The highest Importance Value Index (IVI) was found for Acacia auriculiformis (23.23) followed by Tectona grandis (13.05), Gmelina arborea (12.66), Syzygium fruticosum (12.34), Casuarina equisetifolia (10.57), and Dipterocarpus turbinatus (10.55). The IVI value represents that Acacia auriculiformis possess highest dominance that is followed by Tectona grandis and Gmelina arborea. Percentage distribution of tree individuals into different height classes found in quadrats showed that height range 3 - <8 m had the highest (59.83%) percentage of tree individuals. On the other hand, different dbh (having dbh ≥5 cm) classes showed that most of the trees (65.97%) belonged to dbh range 5 - <15 cm. The outcome of present study suggests for the protection, sustainable management, and conservation of the tree resources of HNP, Cox’s Bazar, Bangladesh.

‘HIJ’ VERSUS ‘ZIJ’: CONTRASTEN, PARALLELLEN EN BEELDSPRAAK IN LAIA FÀBREGAS’ LANDEN (2010)
Authors: Van Raemdonck Anne
Published: February 2021

In this article I shall show how deftly Fàbregas creates in her novel Landen two separate but thematically connected stories and leads them to a very satisfying and totally unexpected ending. Landen is an intriguing psychological novel where the two main characters, Him and Her, tell, in alternating chapters, their own story in the first person. They only meet once, in the first chapter, where the Him character dies. I shall first look at the main characters’ life experiences, i.e. the car accident in which the Her character loses her parents and the experiences of the Him character as an emigrant and later as a widower. I shall then describe the contrasting attitudes they each adopt and look at parallels between both narratives. Finally, I shall give an interpretation of the imagery as a link that also enhances the contrast between the characters.
Power scalability of a continuous-wave high-power Er-Yb co-doped fiber amplifier pumped by Yb-doped fiber lasers

Published: February 2021

The power scaling of Er-Yb co-doped fiber lasers and amplifiers has
been limited by the bottleneck effect of energy-transfer saturation
between Yb ions and Er ions. The emerging method of Er-Yb co-doped
fiber amplifiers pumped by Yb-doped fiber lasers is considered as an
approach to enhance the threshold of the bottleneck effect. In this
paper, we quantitatively characterize the threshold of the bottleneck
effect via the method of extreme value analysis of the second-order
derivative. The method facilitates the optimization of the amplifier
configuration. Afterward, we numerically investigate the bottleneck
effect of various Er-Yb co-doped fiber amplifiers off-peak
cladding-pumped by

Yb-doped fiber lasers for what we
believe, to the best of our knowledge, is the first time. The result
shows that the most optimal configuration is long gain fiber over 20 m
pumped by a 1020–1025 nm fiber laser, with more than two times the
output limit of a conventional laser diode pumping scheme. The
essential factors of an amplifier are discussed afterward, including
the pump-launching direction, the optimization of large-mode-area
fiber, the core-cladding ratio, the concentration of doping ions, the
nonlinearity limit, and the distribution of the heat load.
Multi-resolution analysis of aero-optical effects in a supersonic
turbulent boundary layer

Published: February 2021

Studying the aero-optical effects induced by turbulent structures with different scales
helps determine the capture scale of turbulent structures in
experiments/calculations and improve the turbulence breakup device. In
this paper, the density field of a supersonic turbulent boundary layer
at

M
a
=
3.0

was measured based on the nano-tracer
plane laser scattering technique. Two-dimensional orthogonal wavelet
multi-resolution analysis was applied to obtain information about
different flow scales. The ray-tracing method simulates the
propagation of a Gaussian plane beam through the nonuniform flow field
at different resolutions. The results show that the turbulent boundary
layer thickness and its calculation method lead to the difference in
scaling calculation results among the existing experiments. The
turbulent structures about

0.7
δ

contribute most to aero-optical
effects. With the reduction of the resolution, the contribution of
small turbulent structures to aero-optical effects reduces obviously.
When the minimum scale of turbulent structures captured is larger than

0.072
δ

, the resolution can no longer reflect
the real aero-optics results of turbulent structures. The smallest
optically active scale predicted is

0.017
δ

in Mani’s theory. The turbulent
structures smaller than

0.018
δ

have little effect on optical path
difference (OPD), and the higher-order quantities change significantly
around

it is promising to improve the aero-optical suppression effects by
breaking the large eddy into the turbulent structures smaller than

Published: February 2021

We reported a high-power pure Kerr-lens mode-locked Yb:CALYO laser
based on the dual-confocal cavity delivering sub-100-fs pulses. The
output pulses at 81 MHz have an average power of 10.4 W and the pulse
duration of 98 fs, corresponding to the peak power of 1.14 MW. This
is, to the best of our knowledge, the highest average power ever
reported for a Kerr-lens mode-locked Yb-bulk oscillator. Analysis of
the dual-confocal cavity was also conducted, which indicates a way to
achieve higher average power. We believe the result described in this
Letter may pave a way to develop Kerr-lens mode-locked bulk lasers
with much higher average power.
