Melancholic Relationship to Appearance: A Fanonian Reading of Amadu’s Novel “No Past No Present No Future”
Authors: Kassaw Abera , Mengistu Melakneh
Published: January 2023

This study is an exploration of the melancholic relationship to appearance reflected in Amadu Maddy’s “No Past No Present No Future”. To this end, the researcher uses textual analysis and descriptive criticism to unravel the causes and consequences of melancholic relationship to appearance. The theory of racial melancholia which is dominantly informed by Fanonian approach to the psychology of racism is used to account for the intra-psychic forces which operate within the melancholic characters in the subject novel. As the finding discloses, Amadu’s novel saw at close range that the immediate postcolonial world is dominated by two groups of people: some hermitized white souls whose mindset is stuck in more traditional forms of biological, and pseudo-scientific racism, and those black people with “black skin and white masks.”. Both exist in a borrowed time, unable to come to terms with the psychological states upon which their conscious and unconscious thoughts are hanging, have long lost wellness. The former see their articles of racial superiority as a self-evident truth; the latter plunge into a psychic process whereby the loss of belonging becomes the cause of ongoing trauma, realizing that they belong nowhere, that they must live in a world that would never give recognition to their existence.

The Theory of Investment Behaviour
Authors: - Karanam Supriya , - Akshitha Boddu , - Maheswar Reddy , - Vani Majumdar
Published: January 2023

To provide a new measure of the neoclassical fundamentals that underpin investment spending, we employ profit projections from securities analysts. Even for organizations that are traditionally believed to have liquidity constraints, we find that investment responds considerably to our new measure of fundamentals but is indifferent to cash flow. These findings have two major ramifications. First, contrary to what the outcomes of investment-q models to date would imply, fundamentals might be more significant for investment expenditure. Second, rather than the presence of financial limitations, the positive cash-flow effects observed in such models may be the result of improperly controlling for fundamentals.

On Deriving the Least Squares Estimates in Introductory Regression Courses
Authors: Inlow Mark
Published: January 2023

Introductory regression books typically begin their derivation of the least squares matrix estimation formula by considering the simple linear regression model. We suggest beginning with the zero-intercept model which has advantages. We provide two examples of this approach, one of which is a new, non-calculus derivation using the Cauchy-Schwarz inequality.
Forecasting of Immigrants in Canada using Forecasting models
Authors: Pandher Sharandeep Singh , Arzu Sardarli  , Andrei Volodin
Published: January 2023

In Canada, the number of international students, temporary workers and refugees from every part of the world grows each year. Therefore, forecasting immigration is important for the economy of Canada and Labor Market. In this regard, four forecasting approaches have been applied to the annual data of immigrants for the period 2000-2019. The accuracy of Moving average (MA), Autoregressive (AR), Autoregressive moving average (ARMA), Autoregressive integrated moving average (ARIMA) models were checked via comparing Akaike’s information criteria(AIC), Bayesian information criteria (BIC), Mean error (ME), Root mean square error(RMSE), Mean absolute error (MAE), Mean percentage error (MPE), Mean absolute percentage error (MAPE) and Mean absolute scaled error (MASE) and graphical approaches such as ACF plots of residuals. Experimental results showed that ARIMA (1,2,4) is the best-fitted model for forecasting immigrants in Canada. Selected forecasting approaches are applied to predict immigrants for five years from 2020-2024.
A new modified Bayesian method for measurement uncertainty analysis and the unification of frequentist and Bayesian inference
Authors: Huang Hening
Published: January 2023

This paper proposes a new modification of the traditional Bayesian method for measurement uncertainty analysis.  The new modified Bayesian method is derived from the law of aggregation of information (LAI) and the rule of transformation between the frequentist view and Bayesian view.  It can also be derived from the original Bayes Theorem in continuous form.  We focus on a problem that is often encountered in measurement science: a measurement gives a series of observations.  We consider two cases: (1) there is no genuine prior information about the measurand, so the uncertainty evaluation is purely Type A, and (2) prior information is available and is represented by a normal distribution.  The traditional Bayesian method (also known as the reformulated Bayes Theorem) fails to provide a valid estimate of standard uncertainty in either case.  The new modified Bayesian method provides the same solutions to these two cases as its frequentist counterparts.  The differences between the new modified Bayesian method and the traditional Bayesian method are discussed.  This paper reveals that the traditional Bayesian method is not a self-consistent operation, so it may lead to incorrect inferences in some cases, such as the two cases considered.  In the light of the frequentist-Bayesian transformation rule and the law of aggregation of information (LAI), the frequentist and Bayesian inference are virtually equivalent, so they can be unified, at least in measurement uncertainty analysis.  The unification is of considerable interest because it may resolve the long-standing debate between frequentists and Bayesians.  The unification may also lead to an indisputable, uniform revision of the GUM (Evaluation of measurement data - Guide to the expression of uncertainty in measurement (JCGM 2008)).
Effects of Punch Test Conditions on the Mechanical Response of Polyethylene Materials
Authors: Wen Jiongming , Sun Lei , Gu Chenyi , Zhang Yi
Published: January 2023

Polyethylene (PE) materials have been widely used in industrial and living fields such as natural gas pipelines, drainage pipes, sewage pipes. Punch test is an interesting tool for studying the mechanical properties of materials. However, the deformation behavior involved in punch test is complicated, it is, therefore, essential to investigate the influence of punch test conditions on the mechanical properties of PE materials. Punch tests have been carried out on PE specimens with different punching speed (0.01, 0.1, 1, 10 and 100mm/min) and different punch head diameters (4, 6, 8 and 10mm). The experimental results show that the maximum load from the load-displacement curve increases with the increase of the punch head diameter under the same punch speed. When the punch speed is slow, the force-displacement curve of PE specimens contains four typical stages, namely, elastic stage, yield stage, strain softening stage and strain hardening stage. However, the PE specimen breaks before reaching the strain hardening stage when the punch speed is fast. Similarly, the maximum load increases with the increase of punch speed when the same punch head diameters are used. Furthermore, a three-dimensional finite element (FE) model of PE specimens subjected to punch load has been established to further analyze the deformation and failure behavior. A good agreement between the simulation results and the punch test data is achieved.

Published: January 2023

To analyze the implant overdentures components as following: morphology and composition aspects of several small diameter systems, evaluating both the implant and the retention system (1); biomechanical characteristics of some of the polymers used for manufacturing the overdenture base (2). An experimental in vitro study was carried out through optic microscopy to analyze the metallic structure of dental implants components and anchor systems. The marketed products analyzed were mini1SKY (Bredent) and 3M ESPE MDI Mini dental implant (3M ESPE). A Zeiss microscope with Kohler illumination was used. Samples from polymeric materials commonly used for overdenture based (i.e. Duracryl and Superacryl) were analyzed by 3 point bending test by Tira device. In the case of the mini1SKY system (Bredent), the dental implant has the typical structure of marketed pure titanium that went through thermomechanical processing, resulting in a higher rate of granulation, and the matrix has a completely different structure, as it is a monophasic structure specific to materials that crystalize in the cubic system of the stainless steels. In the case of the 3M ESPE MDI system, the implant and the matrix have a similar microstructure, specific to a Ti-6Al-4V beta alloy annealed with an extremely fine rate of granulation. Duracryl and Superacryl samples fractured variable (frequently close to the midline) and were similar in regard to the value of breaking force. Knowledge of the materials of the components of implant overdenture guide their selection from the point of view of biocompatibility, resistance and ensuring denture retention.

Published: January 2023

Nowadays, research is focused on using bio-degradable natural fibre-based composites for secondary structural members. The present study aims to investigate the effect of fiber loading and surface treatment on the mechanical, vibrational, and viscoelastic properties of short, randomly oriented Abelmoschus Esculentus fiber-reinforced epoxy composites. The composite was fabricated by reinforcing various weight percentages of Abelmoschus Esculentus in epoxy resin by hand lay-up method and tested for tensile, flexural, and impact tests as per ASTM standards. Further, the fibres are treated with alkali to evaluate their effect on the mechanical properties of composites. The analysis indicated that fiber loading had a significant impact on the mechanical properties of the composite, with the maximum tensile strength of 27.8 MPa being obtained at a fiber loading of 20 volume %. The surface treatment of the fiber with 2% NaOH solution increased the tensile strength by 34%. All composite specimens were subjected to vibration analysis. The results showed that composite reinforced with 20% fibre loading provided superior mechanical and damping qualities. Dynamic Mechanical Analysis revealed that the Storage Modulus (E�) improved with the addition of Abelmoschus Esculentus fiiber.

SiO2 nanoparticle were used in aPolyphenylsulfone (PPSU) matrix to obtain nanofiltration membranes used in the pharmaceutical sector to remove pollutants from the water processes. In this study was investigated the influence of SiO2 nanoparticles on the PPSU membranes performance at different concentration of polymer and at six different concentrations of SiO2. Adding SiO2 like additive in the PPSU membrane matrix, the permeability increases due to the higher porosity. Increasing the polymer concentration, the pores are smaller and the permeation properties are decreasing. The affinity for water of membrane surface is higher when nanoparticles are added in the polymer matrix. Adding 0.3 wt.% SiO2 the permeation properties are increasing with more than 10% in comparison with membranes without nanoparticles.

Authors: Zhang Hongshen , Pan Guanghao , Zheng Hongfei
Published: January 2023

Plastic parts in retired passenger vehicles are derived from non-renewable oil resources, and recycling them can conserve energy and reduce the burden on the environment. Effective separation is the premise of recycling vehicle plastics, and electrostatic separation is a clean and efficient method of plastic separation. On the basis of a self-developed, two-stage electrostatic separation equipment, this study investigated the high-voltage electrostatic separation of polyamide (PA), polyethylene (PE), and polypropylene (PP) mixtures. First, the single-factor experiment method was used to explore the influence of voltage, electrode spacing, and electrode inclination angle on the separation results. Second, the response surface methodology was employed to comprehensively analyze the effects of voltage, electrode spacing, and electrode inclination angle on the recovery rates of the three particles and their interactions. The optimum parameters for the secondary electrostatic separation of the three particles were determined to be 44 kV voltage, 156 mm electrode spacing, and 10� electrode inclination. Experimental verification showed that after the two-stage, electrostatic separation device was optimized through the response surface methodology, the purity of the PA particles reached 98.56%, and the recovery rate reached 96%. The purity of the PP particles reached 81.93%, and the recovery rate was 87.5%. Meanwhile, the purity of the PE particles reached 86.11%, and the recovery rate was 73%. This research provides a reference for the multi-stage, high-voltage, electrostatic separation of various automotive plastic particles.

Fiscal Consolidation Strategy: Phased vs. Direct, Which is Better?
Authors: Ramadhan Muhammad Rheza
Published: January 2023

This research aims to examine the impact of fiscal consolidation on the US economy. Since COVID-19 caused the government to cut expenditures due to higher health and business incentive expenditures, fiscal consolidation is required. The analysis is divided into three parts. First, we assume that the decrease in government expenditure is accomplished in the first year. Second, we suppose that government expenditure is progressively reduced, by 0.25% in the first year, 0.50% in the second year, 0.75% in the third year, and 1% in the fourth year. The last scenario predicts that the rest of the globe will follow fiscal consolidation. Following the investigation, we can conclude that fiscal consolidation has a significant long-term influence on the economy. Even while real GDP is declining in the near term, reductions in government expenditure may enhance real GDP in the long run. Based on the comparison of the first and second scenarios, we can conclude that gradual fiscal consolidation is preferable since real GDP does not fall immediately in the first year. Furthermore, we know that the impact of fiscal consolidation in the third scenario is not as favourable as in the first and second scenarios regarding real GDP. As a result, we may assume that the fiscal consolidation policy will be less successful if other nations follow it.

O `Meio´ enquanto dispositivo Heurístico e Intermedial - Uma abordagem às Exposições ´Meio Concreto´ de Alexandre Estrela, e ´Lua Cão` de Alexandre Estrela e João Maria Gusmão e Pedro Paiva
Authors: Serra de Almeida Castelo Branco Sara Marlene
Published: January 2023

Tendo como signo a hibridização e a omnipresença contemporânea de imagens técnicas, este texto tem como alicerce as exposições Meio Concreto (2013) de Alexandre Estrela, e Lua Cão (2017) de Alexandre Estrela e da dupla João Maria Gusmão e Pedro Paiva, que problematizam uma perspectiva dupla do meio enquanto dispositivo heurístico e mecanismo intermedial. A partir de uma análise a estas duas exposições propõe-se neste artigo abordar as forças internas, potenciais e heurísticas dos aparelhos videográficos; a profanação dos automatismos tecnológicos e a estética dos erros técnicos; bem como as relações intermediais existentes na confluência entre o vídeo e a película, e as afinidades e dissemelhanças que esta união gera na concepção de uma porosidade e intersticialidade medial.
A Arte do Vídeo Coreano: do Televisor à Fantasmagoria Pós-cibernética
Authors: Pereira Diogo Sílvia Catarina
Published: January 2023

Enquanto que nos anos 80 a exploração do vídeo como matéria bruta domina o panorama de vídeo coreano, os anos 90 seguem pela exploração da imagem como propriedade do vídeo cujas qualidades podem ser exacerbadas, para, nos anos 2000, com a instalação completamente instaurada, a imagem abrir, lançar-se para fora do ecrã e ir pousar nas paredes de museus e galerias, habitando não apenas o monitor mas tudo quanto pode fazer parte do espaço expositivo. Naquilo que é hoje o vídeo na Coreia do Sul, a imagem domina os mediums na iminência de se imiscuir de forma subreptícia no subconsciente do sujeito. A imagem, por um lado, galvanizante, pretende à supressão visual do medium, de forma a conjurar para o espectador um mundo fantasma, como numa Afterimage ou num efeito Fantasma de Pepper. O medium torna-se desta forma em tudo o que é visível, como havia profetizado Jean-Louis Baudry a par de leituras à obra de Platão.

"Tupi or not Tupi" versus "Casa Portuguesa": Friction between Lúcio Costa and Raul Lino in Auriverde Jornada (or the debate that might have taken place on Identity and Heritage in Architecture)
Authors: Rodrigues dos Santos Joaquim
Published: January 2023

In the book Auriverde Jornada, Raul Lino recounts his meeting with Lúcio Costa in Rio de Janeiro in 1935. That brief shared moment, their personal convictions in relation to architecture and the affinities and divergences that unite/distance them serve as the point of departure for a comparative analysis of their professional journey in the sphere of heritage safeguarding. In fact, as well as landmarks in the architectural landscape of their respective countries, Lino and Costa were also towering figures in the heritage pathway, taking different directions but also sometimes moving in parallel. The animated debate between Lino and Costa on the spirit of modern architecture functions as a catalyst for the present essay, which encompasses a wider problematic: the construction of identity in architecture, the idiosyncrasies of the Modern Movement and the patrimonialization of architecture in Portugal and Brazil, as well as the relations, influences and repercussions that existed in this area between both countries between 1930 and 1960.

Published: January 2023

O objectivo deste artigo é o de salientar as principais características de um conjunto de edifícios construídos de 1904 a 1909 na Avenida Ressano Garcia em Lisboa, a partir do projecto do arquitecto Raul Lino para Joaquim de Jesus Ferreira. Neste projecto o arquitecto enveredou por uma linguagem arquitectónica sóbria, com referências quinhentistas e abordagens novas, inspiradas na arquitectura tradicional portuguesa e na contemporânea anglo-saxónica. Este projeto foi caso único e não teve repercussão no trabalho de outros projetistas e até 1909 foram erigidos edifícios de diferentes tipologias, onde se exploraram conceitos novos. O presente artigo partiu do cotejamento de várias fontes arquivísticas e bibliografia, para salientar a intemporalidade da obra aqui selecionada e que caracteriza, em parte, a arquitectura do início do século XX em Portugal.
Visualizing the transcendental: Irakli Parjiani’s metaphysical landscapes
Authors: Ebanoidze Natia
Published: January 2023

According to contemporary philosophic-aesthetic reflection, the transcendent dimension is essential for human existence and manifests itself in aesthetic experience (Bryl, 1995: 104). Art is by necessity metaphoric and symbolic in nature allowing possibilities for expressing certain kinds of internal experiences not amenable to conceptual explanation. Artistic experience as well as the identity of the picture is by no means transcendental; it reaches beyond the thought, into the extra-ordinary reality that is signified by the picture. Nevertheless, transcending has never been regarded as a systematic objective of studies in art history. The paper explores the concept of transcending in relation to the work of art and examines the ways transcending is realized in the artwork. To elucidate the above issues and illustrate the argument, the paper explores metaphysical landscapes by a Georgian painter Irakli Parjiani (1950-1991).
MicroRNA-181a-5p Curbs Osteogenic Differentiation and Bone Formation Partially Through Impairing Runx1-Dependent Inhibition of AIF-1 Transcription
Authors: Liu Jingwei , Chang Xueying , Dong Daming
Published: January 2023

Background: Evidence has revealed the involvement of microRNAs (miRNAs) in modulating osteogenic differentiation, implying the promise of miRNA-based therapies for treating osteoporosis. This study investigated whether miR-181a-5p influences osteogenic differentiation and bone formation and aimed to establish the mechanisms in depth.Methods: Clinical serum samples were obtained from osteoporosis patients, and MC3T3-E1 cells were treated with osteogenic induction medium (OIM) to induce osteogenic differentiation. miR-181a-5p-, Runt-related transcription factor 1 (Runx1)-, and/or allograft inflammatory factor-1 (AIF-1)-associated oligonucleotides or vectors were transfected into MC3T3-E1 cells to explore their function in relation to the number of calcified nodules, alkaline phosphatase (ALP) staining and activity, expression levels of osteogenesis-related proteins, and apoptosis. Luciferase activity, RNA immunoprecipitation, and chromatin immunoprecipitation assays were employed to validate the binding relationship between miR-181a-5p and Runx1, and the transcriptional regulatory relationship between Runx1 and AIF-1. Ovariectomy (OVX)-induced mice were injected with a miR-181a-5p antagonist for in vivo verification.Results: miR-181a-5p was highly expressed in the serum of osteoporosis patients. OIM treatment decreased miR-181a-5p and AIF-1 expression, but promoted Runx1 expression in MC3T-E1 cells. Meanwhile, upregulated miR-181a-5p suppressed OIM-induced increases in calcified nodules, ALP content, and osteogenesis-related protein expression. Mechanically, miR-181a-5p targeted Runx1, which acted as a transcription factor to negatively modulate AIF-1 expression. Downregulated Runx1 suppressed the miR-181a-5p inhibitor-mediated promotion of osteogenic differentiation, and downregulated AIF-1 reversed the miR-181a-5p mimic-induced inhibition of osteogenic differentiation. Tail vein injection of a miR-181a-5p antagonist induced bone formation in OVX-induced osteoporotic mice.Conclusion: In conclusion, miR-181a-5p affects osteogenic differentiation and bone formation partially via the modulation of the Runx1/AIF-1 axis.

Los actores descritos fueron los alumnos, los docentes, gobiernos, comunidades y empresas, los cuales deben integrarse para lograr, desde su realidad, un desempeño complementario de su saber y hacer en pro del desarrollo social, tomando como norte los objetivos de desarrollo sostenible (ODS).
A Census of the Taurus Star-forming Region and Neighboring Associations with Gaia*
Authors: Luhman K. L.
Published: January 2023

I have used high-precision photometry and astrometry from the third data release of Gaia to perform a survey for members of the Taurus star-forming region and young associations in its vicinity. This work has produced a new catalog of 532 adopted members of Taurus, which has only minor changes relative to the previous catalog from Esplin & Luhman. I have used the Gaia astrometry to divide the Taurus members into 13 groups that have distinct kinematics. Meanwhile, I have identified 1378 candidate members of seven associations near Taurus. All of these associations have histograms of spectral types that peak near M5 (∼0.15 M
⊙), resembling other young populations in the solar neighborhood. For the Taurus groups and neighboring associations, I have estimated ages from their sequences of low-mass stars in Hertzsprung–Russell diagrams. Most of the Taurus groups have median ages of ∼1–3 Myr, while the associations have ages ranging from 13 to 56 Myr. I have used mid-infrared photometry from the Wide-field Infrared Survey Explorer to search for excess emission from circumstellar disks among the candidate members of the associations. Disks are detected for 51 stars, 20 of which are reported for the first time in this work. Some recent studies have proposed that samples of older stars (≳10 Myr) found in the vicinity of Taurus represent a distributed population that is associated with the Taurus cloud complex. However, I find that most of those stars have kinematics that are inconsistent with any relationship with Taurus.
unTimely: a Full-sky, Time-domain unWISE Catalog

We present the unTimely Catalog, a deep time-domain catalog of detections based on Wide-field Infrared Survey Explorer (WISE) and NEOWISE observations spanning the 2010 through 2020 time period. Detections are extracted from “time-resolved unWISE coadds,” which stack together each biannual sky pass of WISE imaging to create a set of ∼16 all-sky maps (per band), each much deeper and cleaner than individual WISE exposures. unTimely incorporates the W1 (3.4 μm) and W2 (4.6 μm) channels, meaning that our data set effectively consists of ∼32 full-sky unWISE catalogs. We run the crowdsource crowded-field point-source photometry pipeline (Schlafly et al. 2018) on each epochal coadd independently, with low detection thresholds: S/N = 4.0 (2.5) in W1 (W2). In total, we tabulate and publicly release 23.5 billion (19.9 billion) detections at W1 (W2). unTimely is ∼1.3 mag deeper than the WISE/NEOWISE Single Exposure Source Tables near the ecliptic, with further enhanced depth toward higher ecliptic latitudes. The unTimely Catalog is primarily designed to enable novel searches for faint, fast-moving objects, such as Y dwarfs and/or late-type (T/Y) subdwarfs in the Milky Way’s thick disk or halo. unTimely will also facilitate other time-domain science applications, such as all-sky studies of quasar variability at mid-infrared wavelengths over a decade-long time baseline.
Three Loxocaudinae species (Ostracoda, Podocopida) from South Korea

Published: January 2023

For many ostracod groups in Korea, published records are missing or are very limited. Loxocaudinae is one such subfamily, with only one named species, Loxocauda orientalis Schornikov, 2011 reported from Korea. Having fewer than 50 species, this subfamily can be considered a small ostracod group, with most of the species known only by their shell morphology. The diagnoses of genera are based on the shell characters that are often homoplastic, and soft body appendages that are difficult to observe, such as the mandibular exopodite. Because of this, the validity of the entire subfamily and some of its genera have been questioned. Here three Loxocaudinae species were collected from the marine macrobenthic assemblages from Korea. Two are new and belong to the genus Glacioloxoconcha Hartmann, 1990, previously known only from Antarctica: Glacioloxoconcha jeongokensissp. nov. and Glacioloxoconcha jisepoensissp. nov.Loxocauda orientalis is briefly redescribed, with some of the populations having unusual morphological features. COI and 18S rRNA sequences of all three species are provided and the latter marker used to assess the position of the subfamily within the family Loxoconchidae and the superfamily Cytheroidea. The resulting tree shows that within the family Loxoconchidae, the genera Glacioloxoconcha and Loxocauda Schornikov, 1969 are the most closely related, with very shallow but well-supported branches. Polyphyletic and paraphyletic natures of several Cytheroidea families are discussed, inferred from the reconstructed phylogeny.
A new freshwater amphipod (Amphipoda, Gammaridae), Gammarus tumaf sp. nov. from the Gökgöl Cave, Türkiye
Authors: Özbek Murat , Aksu İsmail , Baytaşoğlu Hazel
Published: January 2023

A new amphipod species belonging to the genus Gammarus is described from the Gökgöl Cave, Zonguldak Province, Türkiye. The newly-identified species is relatively small (13 mm) and is a member of the Gammarus pulex-group by the presence of numerous long setae along the posterior margins of pereopods 3 and 4. The specimens were sampled from a shallow pond located in the dark zone (about 1 km inside the entrance) of the cave. Minute eyes, setose (both peduncle and flagellar segments) second antenna, slightly swollen flagellar segments of the second antenna, setose pereopods 3 and 4 and relatively short endopod/exopod ratio of the third uropod are the character combination of the newly-identified species in addition to lacking body pigmentation. The molecular phylogeny, based on the concatenated dataset (28S+COI, 1495 bp) indicated that the new species was resolved from the other Gammarus species by high bootstrap (NJ: 100, ML: 100). In addition to Gammarus tumafsp. nov., mtDNA COI and nuclear DNA 28S gene data of Gammarus baysaliÖzbek et al., 2013 were recorded for the first time. The newly-identified species was well-differentiated from the genetically closest species, G. baysali, with genetic distance of 12.22% and 0.55% for the COI and 28S genes, respectively. Detailed descriptions and drawings of the extremities of the holotype male were given and the morphology of the newly-identified species is compared with its relatives.

Freshwater mussels belonging to the genus Cristaria Schumacher, 1817 (Bivalvia: Unionidae) are widespread from Mongolia to Indochina while the range of one species, C. plicata (Leach, 1814), covers two biogeographic subregions, i.e., East Asian (Amur River to Vietnam) and Sundaland (Mekong River basin). We present here a taxonomic revision of the nominal taxon Anodonta bellua Morelet, 1866 which was described from the Mekong (Lake Tonle-Sap, Cambodia) but is currently considered a synonym of C. plicata. We obtained molecular data for newly collected Cristaria representatives from the Mekong’s tributaries in Laos, which were found as a divergent species-level phylogenetic clade within the genus that is distant from C. plicata. Nevertheless, comparative morphological and morphometric studies did not reveal any significant differences between these two congeners. Our time-calibrated biogeographic modeling reveals that the split between Cristaria bellua (Mekong) and C. clessini (East Asia) probably occurred in the mid-Miocene (15.8 Ma) and may reflect an ancient stream capture between the Mekong Basin and East Asian rivers.
Graded modules with Noetherian graded second spectrum

Published: January 2023

Let $ R $ be a $ G $ graded commutative ring and $ M $ be a $ G $-graded $ R $-module. The set of all graded second submodules of $ M $ is denoted by $ Spec_G^s(M), $ and it is called the graded second spectrum of $ M $. We discuss graded rings with Noetherian graded prime spectrum. In addition, we introduce the notion of the graded Zariski socle of graded submodules and explore their properties. We also investigate $ Spec^s_G(M) $ with the Zariski topology from the viewpoint of being a Noetherian space.
