Abstract:

ABSTRAKWireless Sensor Networ (WSN) merupakan jaringan nirkabel terdiri dari kumpulan node sensor tersebar di lingkungan observasi, saling berkomunikasi sesuai dengan algoritma komunikasi. Salah satu penerapan WSN adalah lokalisasi berbasis RSSI. RSSI merupakan hasil lokalisasi yang bersifat fluktuatif disebabkan oleh fenomena multipath fading, sehingga berpengaruh terhadap hasil lokalisasi. Artikel ini menerapkan Filter Kalman (FK) untuk lokalisasi Outdoor berbasis RSSI dengan komunikasi LoRa untuk lima Node Diam (ND) dan empat Node Anchor (NA). Pengujiannya terdiri dari membandingkan FK dengan tanpa FK, dan FK dengan metode Normalisasi. FK dapat memperbaiki akurasi pada estimasi jarak dan posisi. FK memperbaiki akurasi estimasi jarak sebesar 0,57% untuk ND1; 0,19% untuk ND2; 4,59% untuk ND3; 0,73% untuk ND4 dan 20,11% untuk ND5. Pada estimasi posisi, FK dapat meningkatkan akurasi sebesar 2,45% untuk ND1; 11,19% untuk ND2; 6,03% untuk ND3; 7,64% untuk ND4; dan 5,42% untuk ND5. Selain itu, FK dapat memperbaiki akurasi 15,94% untuk ND1; 3,41% untuk ND 2 dan 15,76% untuk ND 4 terhadap metode Normalisasi.Kata kunci: Filter Kalman, Localization,LoRa, RSSI, Wireless Sensor Network ABSTRACTWireless Sensor Network (WSN) is a wireless network consisting of sensor nodes spread across an observation environment, communicating with others separately according to a communication algorithm. In addition, one of the WSN applications is RSSI-based localization. RSSI is the development of localization which fluctuates due to the multipath fading phenomenon, thus affecting the localization results. This article executes a Kalman Filter (KF) for RSSI-based Outdoor localization with LoRa communication for five Diam Nodes (ND) and four Anchor Nodes (NA). The experiment involves comparing KF with neither KF nor the Normalization method. KF can improve the accuracy of distance and location estimation. FK increases the distance estimation accuracy by 0,57% for ND1; 0,19% for ND2; 4,59% for ND3; 0,73% for ND4; and 20,11% for ND5. For ND1, ND2, ND3, ND4, and ND5, KF can improve position estimation accuracy by 2,45%, 11,19%, 6,03%, 7,64%, 5,42%, and 2,45%, respectively. In addition, KF can increase accuracy by 15,94% for ND1, 3,41% for ND2, and 15,76% for ND4 in comparison to the Normalization approach.Keywords: Kalman Filter, Localization, LoRa, RSSI, Wireless Sensor Network

Abstract:

Informatization is defined as the process by which information technologies, such as the World Wide Web and other communication technologies, have transformed economic and social relations to such an extent that cultural and economic barriers are minimized. What does this mean for nondestructive testing and evaluation (NDT/E)? In short: informatization in NDT and NDE has happened and will continue to happen, independent of whether individuals or companies like it or not. However, we can shape it—together.

Abstract:

Alcichthys elongatus is the only species in the genus, and this work is the first to provide a comprehensive mitogenome analysis of this species. The A. elongatus mitogenome was 16,712 bp long, with biased A + T content (52.33%), and featured thirteen protein-coding genes (PCGs), twenty-two tRNAs, two rRNAs, and the control region (D-loop). The H strand encoded twenty-eight genes (twelve PCGs, fourteen tRNA, and two rRNA) and the control region, whereas the L strand encoded the remaining nine genes (ND6 and eight tRNA). Except for COXI, which started with GTG, all PCG sequences started with ATG and ended with TAA (ND4L, ND5, COXI, ATP8) or TAG (ND1, ND6) termination codons, with some (ND2, ND3, ND4, COXII, COXIII, ATP6, Cytb) having an incomplete termination codon. Except for tRNA-serine-1 (trnS), the majority of the tRNAs exhibited characteristic cloverleaf secondary structures. Based on 13 PCGs, phylogenetic analysis placed A. elongatus in the same clade as Icelus spatula. This genomic data will be useful for species identification, phylogenetic analysis, and population genetics.

Abstract:

Mitochondrial genomics, as a useful marker for phylogenetics and systematics of organisms, are important for molecular biology studies. The phylogenetic relationships of the Polypedilum generic complex remains controversial, due to lack taxonomy and molecular information. In this study, we newly sequenced mitogenomes of 14 species of the Polypedilum generic complex. Coupled with three recently published sequences, we analyzed the nucleotide composition, sequence length, and evolutionary rate of this generic complex. The control region showed the highest AT content. The evolution rate of protein coding genes was as follows: ATP8 > ND6 > ND5 > ND3 > ND2 > ND4L > ND4 > COX1 > ND1 > CYTB > APT6 > COX2 > COX3. We reconstructed the phylogenetic relationships among the genera within the Polypedilum generic complex based on 19 mitochondrial genomes (seventeen ingroups and two outgroups), using Bayesian Inference (BI) and Maximum Likelihood (ML) methods for all databases. Phylogenetic analysis of 19 mitochondrial genomes demonstrated that the Endochironomus + Synendotendipes was sister to Phaenopsectra + Sergentia.

Abstract:

Extreme weather poses huge challenges for animals that must adapt to wide variations in environmental temperature and, in many cases, it can lead to the local extirpation of populations or even the extinction of an entire species. Previous studies have found that one element of amphibian adaptation to environmental stress involves changes in mitochondrial gene expression at low temperatures. However, to date, comparative studies of gene expression in organisms living at extreme temperatures have focused mainly on nuclear genes. This study sequenced the complete mitochondrial genomes of five Asian hylid frog species: Dryophytes japonicus, D. immaculata, Hyla annectans, H. chinensis and H. zhaopingensis. It compared the phylogenetic relationships within the Hylidae family and explored the association between mitochondrial gene expression and evolutionary adaptations to cold stress. The present results showed that in D. immaculata, transcript levels of 12 out of 13 mitochondria genes were significantly reduced under cold exposure (p < 0.05); hence, we put forward the conjecture that D. immaculata adapts by entering a hibernation state at low temperature. In H. annectans, the transcripts of 10 genes (ND1, ND2, ND3, ND4, ND4L, ND5, ND6, COX1, COX2 and ATP8) were significantly reduced in response to cold exposure, and five mitochondrial genes in H. chinensis (ND1, ND2, ND3, ND4L and ATP6) also showed significantly reduced expression and transcript levels under cold conditions. By contrast, transcript levels of ND2 and ATP6 in H. zhaopingensis were significantly increased at low temperatures, possibly related to the narrow distribution of this species primarily at low latitudes. Indeed, H. zhaopingensis has little ability to adapt to low temperature (4 °C), or maybe to enter into hibernation, and it shows metabolic disorder in the cold. The present study demonstrates that the regulatory trend of mitochondrial gene expression in amphibians is correlated with their ability to adapt to variable climates in extreme environments. These results can predict which species are more likely to undergo extirpation or extinction with climate change and, thereby, provide new ideas for the study of species extinction in highly variable winter climates.

Abstract:

(1) Background: Mitochondrial genomes are important markers for the study of phylogenetics and systematics. Triozidae includes some primary pests of Populus euphratica. The phylogenetic relationships of this group remain controversial due to the lack of molecular data. (2) Methods: Mitochondria of Egeirotrioza Boselli were sequenced and assembled. We analyzed the sequence length, nucleotide composition, and evolutionary rate of Triozidae, combined with the 13 published mitochondrial genomes. (3) Results: The evolutionary rate of protein-coding genes was as follows: ATP8 > ND6 > ND5 > ND2 > ND4 > ND4L > ND1 > ND3 > APT6 > CYTB > COX3 > COX2 > COX1. We reconstructed the phylogenetic relationships of Triozidae based on 16 triozid mitochondrial genomes (thirteen ingroups and three outgroups) using the maximum likelihood (ML) and Bayesian inference (BI) approaches. The phylogenetic analysis of the 16 Triozidae mitochondrial genomes showed that Egeirotrioza was closely related to Leptynoptera. (4) Conclusions: We have identified 13 PCGs, 22 tRNAs, 2 rRNAs, and 1 control region (CR) of all newly sequenced mitochondrial genomes, which were the mitochondrial gene type in animals. The results of this study provide valuable genomic information for the study of psyllid species.

Abstract:

Blissidae (the Chinch bug) is a group with high species richness in Lygaeoidea, but there are only a few descriptions of mitochondrial genomes available. We obtained mitogenomes from 10 species of eight genera from Blissidae through second-generation sequencing technology. The length of the mitochondrial genome (excluding the control region) is between 14643 and 14385 bp; the content of AT is between 74.1% and 77.9%. The sequence of the evolution rate of protein coding genes was as follows: ND5 > ATP8 > ND6 > ND2 > ND4 > ND4L > ND1 > ATP6 > ND3 > COIII > COII > CYTB > COI. The mitogenomic structure of Blissidae is highly conservative. Gene rearrangement is only found in Pirkimeru japonicus (PiGXBS1), which is formed as the duplication of tRNA-H. The intergenic spacer between ND4 and tRNA-H, which form an obvious stem-and-loop structure, was found in all samples in this study. The phylogenetic trees generated by BI and ML indicated that Blissidae can be divided into three major clades: Clade A (only included Macropes); Clade B ((Pirkimerus + Bochrus) + Iphicrates); and Clade C ((Ischnodemus + Capodemus) + (Cavelerius + Dimorphopterus)). The divergence within the Blissidae began at about 56 Ma. At the genus level, the divergence was concentrated at 30–51 Ma, slightly later than the diversification of Poaceae. The consistency of divergence time between Blissidae and Poaceae might hint at the coevolutionary relationship between them, but further molecular and biological evidence is still needed to prove it.

Abstract:

In contrast to conventional non-destructive testing (NDT) and non-destructive evaluation (NDE) methodologies, including radiography, ultrasound, and eddy current analysis, coplanar capacitive sensing technique emerges as a novel and promising avenue within the field. This paper endeavors to elucidate the efficacy of coplanar capacitive sensing, also referred to as capacitive imaging (CI), within the realm of NDT. Leveraging extant scholarly discourse, this review offers a comprehensive and methodical examination of the coplanar capacitive technique, encompassing its fundamental principles, factors influencing sensor efficacy, and diverse applications for defect identification across various NDT domains. Furthermore, this review deliberates on extant challenges and anticipates future trajectories for the technique. The manifold advantages inherent to coplanar capacitive sensing vis-à-vis traditional NDT methodologies not only afford its versatility in application but also underscore its potential for pioneering advancements in forthcoming applications.

Abstract:

The sea turtles (Cheloniidae) are a group of seven species of cretaceous origin. Analyses of partial mitochondrial sequences have revealed phylogenetic inconsistences within this group. Nevertheless, these mitochondrial markers have allowed us to understand, explain and clarify population composition in areas of foraging, reproductive habits, inferences of migration patterns and, also, to define management units in the world, in order to trace conservation and monitoring plans. In this study, four methods were evaluated and compared for phylogenetic inference (Neighbor-Joining-NJ, Maximum Likelihood-ML, Maximum Parsimony-MP and Bayesian inference-BI) by using coding genes, ribosomal genes and full mitogenomes of the hawksbill, E. imbricata, and other six species of sea turtles obtained from GenBank. The sequences were analyzed independently and jointly to identify the method and marker that better explain the phylogenetic relationships among this group of reptiles. The NJ, ML, MP and BI trees showed that ND2, COX1, 16S rRNA, ND5, 12S rRNA, ND4 and COX3 are the markers that give phylogenetic trees with better resolution and support, with bootstrap values ranging from 89.0% to 99.98%. ATP6, ATP8, COX2, ND1, ND3, ND5 and ND4L genes presented polytomies. The analysis with full mitogenome often provides highly supported trees (bootstrap 98.0%) compared with single marker analysis. Trees obtained with the BI method and the ND2 gene is the one that better resolved the evolutionary relationships among the species, consolidating the position of E. imbricata within the Carettini tribe with a value of posterior probability of 0.98-1.0. The markers ND2, ND4, ND5 and COIII, not used in previous works, represent a new alternative to explain the phylogeny in this group of marine reptiles. In the present study, a complete mitogenome analysis produced robust and highly supported trees.

Full text

Abstract:

Aflatoxin B1 (AFB1) is a highly toxic mycotoxin that causes severe suppression of the immune system of humans and animals, as well as enhances reactive oxygen species (ROS) formation, causing oxidative damage. However, the mechanisms underlying the ROS formation and immunotoxicity of AFB1 are poorly understood. This study used the mouse macrophage RAW264.7 cell line and whole-transcriptome sequencing (RNA-Seq) technology to address this knowledge-gap. The results show that AFB1 induced the decrease of cell viability in a dose- and time-dependent manner. AFB1 also significantly increased intracellular productions of ROS and malondialdehyde and decreased glutathione levels. These changes correlated with increased mRNA expression of NOS2, TNF-α and CXCL2 and decreased expression of CD86. In total, 783 differentially expressed genes (DEGs) were identified via RNA-Seq technology. KEGG analysis of the oxidative phosphorylation pathway revealed that mRNA levels of ND1, ND2, ND3, ND4, ND4L, ND5, ND6, Cyt b, COX2, ATPeF0A and ATPeF08 were higher in AFB1-treated cells than control cells, whereas 14 DEGs were downregulated in the AFB1 group. Furthermore, seven immune regulatory pathways mediated by oxidative stress were identified by KEGG analysis. Altogether, these data suggest that AFB1 induces oxidative stress in macrophages via affecting the respiratory chain, which leads to the activation of several signaling pathways related to the inflammatory response.

Abstract:

The arrangement of protein and rRNA encoding genes in the mitochondrial genome of Haliotis conicopora (Vetigastropoda, Gastropoda, Mollusca) has been partly determined using standard PCR methods. Two gene complexes, one including COIII/ ND3/ND2/COI/COII/ATP8/ATP6, and the other including 12S/16S/ND1/ND6/Cyt b/ND4L/ND4/ND5, are clarified. It is revealed that, if tRNA genes are ignored, the mitochondrial gene order of Haliotis conicopora is in agreement with that of Haliotis rubra (Vetigastropoda, Gastropoda, Mollusca) (NC_005940).

Abstract:

AbstractIntroduction/AimsAmyotrophic lateral sclerosis (ALS) may be familial or sporadic, and twin studies have revealed that even sporadic forms have a significant genetic component. Variants in 55 nuclear genes have been associated with ALS and although mitochondrial dysfunction is observed in ALS, variants in mitochondrial genomes (mitogenomes) have not yet been tested for association with ALS. The aim of this study was to determine whether mitogenome variants are associated with ALS.MethodsWe conducted a genome‐wide association study (GWAS) in mitogenomes of 1965 ALS patients and 2547 controls.ResultsWe identified 51 mitogenome variants with p values <10−7, of which 13 had odds ratios (ORs) >1, in genes RNR1, ND1, CO1, CO3, ND5, ND6, and CYB, while 38 variants had OR <1 in genes RNR1, RNA2, ND1, ND2, CO2, ATP8, ATP6, CO3, ND3, ND4, ND5, ND6, and CYB. The frequencies of haplogroups H, U, and L, the most frequent in our ALS data set, were the same in different onset sites (bulbar, limb, spinal, and axial). Also, intra‐haplogroup GWAS revealed unique ALS‐associated variants in haplogroups L and U.DiscussionOur study shows that mitogenome single nucleotide variants (SNVs) are associated with ALS and suggests that these SNVs could be included in routine genetic testing for ALS and that mitochondrial replacement therapy has the potential to serve as a basis for ALS treatment.

Abstract:

AbstractThe genus Eristalinus is widely distributed globally. Four complete mitochondrial genomes (i.e., mitogenomes) of Eristalinus were sequenced and analyzed in this study: Eristalinus viridis (Coquillett, 1898), E. quinquestriatus (Fabricius, 1781), E. tarsalis (Macquart, 1855), and E. sp. Within these four sequenced mitogenomes, most protein-coding genes (ND2, CO1, COX2, COX3, ND3, ND5, ND4, ND4L, ND6, and Cytb) began with a typical ATN (T/C/G/A) start codon and ended with a stop codon TAA or incomplete T, whereas ND1 began with the start codon TTG. ND3 ended with TAG. The secondary tRNA structure was that of a typical cloverleaf, and only the tRNA-Ser1 lacked a DHU arm. Three and five domains appeared in the 12S and 16S rRNA secondary structures, respectively. The phylogenetic relationships among the four Eristalinus species combined with the published mitogenomes of Syrphidae were reconstructed using the maximum likelihood and Bayesian inference methods, which support the monophyly of the subfamily Syrphinae but do not support that of the subfamily Eristalinae. Of note, Eristalini and Syrphini are monophyletic groups. The mitogenomes of E. viridis, E. quinquestriatus, E. sp., and E. tarsalis are useful for determining the phylogenetic relationships and evolution of Syrphidae.

Full text

Abstract:

The main challenge to the automation of NDE is the compound problem between the wide variety of NDT (non-destructive technique) available coupled with the diversity of infrastructures to be inspected. In some cases, the identification of flaws may require multiple complementary NDT to assert confidence in the results, adding further complexity to the issue. In this context, developing an automated system applicable to a wide variety of inspection conditions is an arduous task. Yet, targeting a wide range of applications, reducing inspection time or increasing safety are all essential factors to making such development worthwhile. This study aims to achieve the automation or semi-automation of ultrasonic NDT for concrete inspection using a UAV. Two NDT techniques are being considered, Impact Echo and Ultrasonic testing using Dry Point Contact transducers. Challenges regarding the mechanical and electric implementation of the NDT payloads to the UAV as well as the impact of the UAV on the recorded NDT data will be discussed and initial results will be presented.

Full text

Abstract:

Different materials within the Nuclear Power Plants (NPP) concrete structure can undergo ageing process which causes defects in the materials and can lose, partially or totally, their designed function. The typical defects include corrosion of reinforcement steel, delamination, cracks, malfunction of post-tensioning or steel composite systems etc. The testing methods to detect the defects of concrete structures are (i) destructive examinations and (ii) non-destructive testing (NDT). The challenges for assessing the performance of the NPP concrete structures using (NDT) methods include (i) the limited access time (only during the annual overhauls) and (ii) the accuracy and reliability of the available NDT testing devices. To overcome these challenges, a mock-up wall representing a section of the concrete containment of the NPP was built. Simulated defects and errors were embedded inside the wall such as dimensional errors, honeycombing, delamination, and voids in the post-tensioned grouted tendon ducts. Different NDT techniques and combinations were used for assessing the simulated defects of the mock-up wall. These techniques included basic NDT methods as rebound hammer, ultrasonic pulse velocity (UPV) and concrete cover meter and advanced NDT as Ground Penetrating Radar (GPR) and ultrasonic pulse echo (MIRA and MONOLITH). The results of basic NDT techniques as concrete cover meter, rebound hammer and UPV presented the basic characteristic properties of the concrete mock-up wall as concrete cover depth, compressive strength, and quality of concrete. The use of advanced NDT as GPR and MIRA and MONOLITH enabled us to detect and locate the embedded defect and the construction faults inside the mock-up wall. We conclude that the construction of the with simulated defects offers the possibility to investigate accuracy and reliably of the available NDT methods and increases the field experts’ skills providing also an important and very much needed educational platform for future NDE experts.
