Published: January 2024

Morphological identification often fails to reveal the taxonomic status of fish larvae. DNA barcoding using particular DNA segment is frequently successful in solving the faulty and might reveal overlooked species, including species outside their recognized geographic ranges, such as Eastern Atlantic seabream Sparus aurata. This study aims to assess fish larvae diversity in Teluk Penyu Beach, Cilacap Central Java, Indonesia, through the cytochrome c oxidase 1 barcoding. Fish larvae were collected using a larva net with a diameter of 60 cm and height of 150 cm and horizontal towing during the field trips in March and April 2021. Larvae morphotypes were determined based on their general morphological performance observed under a magnification lens according the available references. Eighteen larvae morphotypes were successfully barcoded, and 5% genetic distance was used as a species border. Fourteen fish larvae species were revealed, with intraspecific genetic distances between 0.00% and 4.12%, while intrageneric genetic distances ranged from 5.50% to 19.29%. An interesting finding was that one larva morphotype was barcoded as S. aurata with high genetic identity (99.19% to 99.68%) and low genetic distance (0.32% to 0.81%). The discovery provides the first new data on S. aurata in Teluk Penyu Beach Cilacap, Central Java, outside its recognized geographic range. Overall, this study provides information about fish larvae in Teluk Penyu Beach, essential for estimating the number and species of fish recruited in the southern Cilacap, which is vital for fisheries management. Nevertheless, new research requires further clarification of S. aurata in Teluk Penyu Beach.

The contribution made by the crew is very important for the welfare of the company and the performance on board. But their well-being has not been paid enough attention in the maritime world. Heavy workloads and working hours and lack of implementation of rest hours trigger human error and are prone to fatigue. The implementation of the Maritime Labor Convention 2006 has contributed significantly to the improvement of the working conditions of the crew. The purpose of this study is to determine the right criteria and strategic solutions in helping to improve the application of rest hours to crew members. Criteria and strategy solutions were obtained through the Analytical Hierarchy Process (AHP) and Expert Choice methods are used as supporting software for calculations. The stages of observation, interviews, dissemination of questionnaires, modeling and choice are processes carried out in data processing. Rest time criterias with a weight value of 0.534 and an inconsistency value of 0.004466 was the main criteria chosen by the respondents. Meanwhile, Sleep Duration is a strategy solution chosen as the top priority with the weight value of 0.220 with an inconsistency value of 0. The results of the two inconsistencies each have a CR value of < 0.1 indicating that the results of rest hour application data processing based on the 2006 Maritime Labor Convention can be declared consistent and accurate.
Which approach best promoted low-proficiency learners’ listening performance: metacognitive, bottom-up or a combination of both?
Authors: Yuan Xin , Tang Xuan 
Published: January 2024

Abstract
This study examined the effects of a 10-week metacognitive instruction on low-proficiency Chinese EFL learners’ listening performance. It also explored the relative effectiveness of metacognitive instruction, bottom-up instruction and a combination of the two types of instructions on learners’ listening performance. Eighty low-proficiency Chinese college students were assigned to one control group and three experimental groups. One experimental group received metacognitive instruction, another experimental group received bottom-up listening strategy training and the third experimental group was exposed to a combination of the aforementioned trainings. The control group did not receive any training. The linear mixed effects model (LMM) results indicated that the integrated approach was the most effective at improving low-proficiency listeners’ listening performance, followed by bottom-up training. The metacognitive instruction alone did not prove useful at promoting the development of listening performance. The pedagogical implications of the study are also discussed.
Why is L2 pragmatics still a neglected area in EFL teaching? Uncovered stories from Vietnamese EFL teachers
Authors: Ton-Nu Anh 
Published: January 2024

Abstract
Despite receiving more attention and obtaining a well-established status in second language (L2) teaching research during the last three decades, L2 pragmatics remains an excluded topic in English as a foreign language (EFL) teaching in many investigated contexts. Adopting a qualitative case study design, this paper examines what seven EFL teachers from different Vietnamese high schools perceive about L2 pragmatics and instructional pragmatics and reflect on their teacher preparation programs in these regards. The findings reveal that the participating teachers were not taught about L2 pragmatics and instructional pragmatics during their professional education, resulting in their little content and pedagogical knowledge of L2 pragmatics. This leads to their general exclusion of L2 pragmatics teaching in their classroom practices. The uncovered stories from these teachers provide essential implications for teacher education programs in Vietnam and its similar contexts. Importantly, they add more understanding to the relationship of teachers’ knowledge and their practices of L2 pragmatics teaching, a current understudied research area with specific reference to teacher cognition of L2 pragmatics.

Abstract
Analysis of huge data and detection of scintillation events by human visualization is expensive and time consuming process and also unfeasible in real time. In this paper, classical approaches namely Hard, Semi-Hard and Manual annotation rules are used for detection of the scintillations. For this, one week data is acquired from Septentrio PoLaRx5S GNSS scintillation monitoring Receiver corresponding to various constellations. Seven constellations namely GPS, GLONASS, Galileo, SBAS, BeiDou, QZSS and IRNSS-L5 signals during pre-sunset and post sunset hours are considered. The occurrence of scintillations due to pre-sunset and post sunset period by using hard and semi hard detection rules are analysed. It is observed that the occurrence of scintillations is more in post-sunset hours as compared to pre-sunset hours in all constellations. The performances of Semi Hard and Hard detection rules are compared with manual annotation by using confusion matrices statistical parameters namely accuracy, misclassification and precision. Identified scintillation signals coming from the least and worst affected directions. These results would be useful for early detection of scintillation without human inspection of scintillation events.

ABSTRACT
This article summarizes the development of the 2023 New Zealand ground-motion database (NZGMDB). A preceding version was formally used as the central ground-motion database in the ground-motion characterization modeling for the 2022 New Zealand (NZ) National Seismic Hazard Model (NSHM) revision. The database contains ground motions for events with a moment magnitude greater than ∼3.0 from the years 2000 to the end of 2022. Several challenges associated with NZ earthquake source metadata are explained, including determination of earthquake location, magnitude, tectonic classification, and finite-fault geometry, among others. The site table leverages the site database developed as a part of the 2022 NZ NSHM revision, and several definitions of source-to-site distance are computed for the propagation path table. The ground-motion quality classification was initially assessed using a neural network. Subsequent waveform quality verification was conducted and additional quality criteria were enforced to ensure a sufficiently high-quality database. Standard processing techniques were applied to the ground motions before intensity measure (IM) calculation. IMs in the database include peak ground acceleration, 5%-damped pseudoacceleration response spectra, smoothed Fourier amplitude spectra, and other cumulative and duration-related metrics. The NZGMDB is publicly available and routinely updated as new and higher quality data become available.
Exploiting the Potential of Urban DAS Grids: Ambient-Noise Subsurface Imaging Using Joint Rayleigh and Love Waves
Authors: Ji Qing , Luo Bin , Biondi Biondo 
Published: January 2024

Abstract
Distributed acoustic sensing (DAS) data become important for seismic monitoring of subsurface structures in urban areas. Different from the previous studies that only focused on Rayleigh waves, we report successful observation and analysis of both Rayleigh and Love waves extracted from ambient-noise interferometry, using orthogonal segments of fiber-optic cables in San Jose, California. Theoretical angular responses of DAS ambient-noise cross correlation, together with numerical experiments, help identify DAS channel pairs expected to record stronger Love waves than Rayleigh waves. Based on these waveforms, we further obtain clear Rayleigh- and Love-wave dispersion maps, including both phase and group velocities, with various channel pair orientations. Finally, we perform a joint inversion of Rayleigh- and Love-wave dispersion curves to obtain depth-dependent subsurface velocity structures of the top 100 m. Our inversion result is consistent with the model from the previous study based on Rayleigh-wave dispersion and horizontal-to-vertical spectral ratio. In addition, the joint inversion of Love and Rayleigh is more robust than that of the independent inversion of either type of wave. Our new study demonstrates the potential of surface-wave analysis on fiber-optic cables with complex geometry, which can further advance the seismic monitoring of urban areas.

Prostate cancer is a type of cancer that occurs in men and requires an effective therapeutic approach. Treatment of prostate cancer depends on the stage at diagnosis. In advanced stages of prostate cancer can be treated with hormone therapy such as chemotherapy which is then followed by vaccine therapy which aims to help increase the body's immune system response to prostate cancer cells. This model consists of a system of ordinary differential equations with five variables used, including androgen-dependent prostate cancer cells, androgen-independent prostate cancer cells, dendritic cells, effector cells, and curative vaccines. Then two equilibrium point conditions are produced, when there is no vaccine for disease free conditions and endemic conditions , then when the vaccine there are three equilibrium conditions namely disease free , side effects and local existence between prostate cancer cells with vaccine . The results of the stability analysis for each equilibrium point show that when , the condition is global asymptotic, while the condition is stable because the eigenvalue is negative. When for the condition it is unstable because the two roots are positive, then for the condition it is global asymptotic and for the condition it is asymptotically local because all the eigenvalues are negative. The numerical simulations of equilibrium points obtained using the fourth order runge-kutta method according to different q parameter values show that the larger the dendritic cells and effector cells activated, the greater the vaccine that enters the body, resulting in immune cells that will fight prostate cancer cells.

Los desequilibrios geodemográficos en Canarias: una expresión de su especialización económica
Authors: Jerez Darias Luis Manuel , García Cruz Juan Israel 
Published: January 2024

Canarias es actualmente la tercera comunidad autónoma con mayor densidad de población detrás de Madrid y País Vasco. Con casi 2,2 millones de habitantes, más una carga de 237 556 turistas/día, se articula un espacio fragmentado con una distribución de la población muy polarizada territorialmente, tanto a nivel regional como en cada isla. La dinámica común en todas ellas ha tendido a una litoralización creciente de las actividades económicas y residenciales, frente a un amplio espacio insular escasamente poblado. Este estudio pretende actualizar el análisis geodemográfico sobre la distribución de la población en Canarias, atendiendo a la relación economía-población. Se plantea que la creciente especialización de su economía en el sector terciario, con fuerte dependencia del turismo, ha profundizado el desequilibrio geodemográfica en las Islas. Para ello, se aplica una metodología apoyada en el manejo de la bibliografía, el análisis geoestadístico, datos económicos y la representación cartográfica del fenómeno analizado a distintas escalas.

Abstract
Bacteria dysbiosis has been associated with an increased risk of HIV-1 transmission and acquisition. The prevalent idea is that bacteria dysbiosis compromises mucosal integrity and promotes inflammatory conditions to cause recruitment and activation of immune cells that harbor or are targeted by HIV-1. However, it is also possible that HIV-1 directly binds bacteria or bacterial products to impact virus infectivity and transmissibility. This study evaluated HIV-1 interactions with bacteria through glycan-binding lectins. The StreptococcalSiglec-like lectin SLBR-N, which is part of the fimbriae shrouding the bacteria surface and recognizes α2,3 sialyated O-linked glycans, was noted for its ability to enhance HIV-1 infectivity in the context of cell-free infection and cell-to-cell transfer. Enhancing effects were recapitulated with O-glycan-binding plant lectins, signifying the importance of O-glycans. Conversely, N-glycan-binding bacterial lectins FimH and Msl had no effect. SLBR-N was demonstrated to capture and transfer infectious HIV-1 virions, bind to O-glycans on HIV-1 Env, and increase HIV-1 resistance to broadly neutralizing antibodies targeting different regions of Env. Hence, this study highlights the potential contribution of O-glycans in promoting HIV-1 infection through the exploitation of O-glycan-binding lectins from commensal bacteria at the mucosa.
