Published: January 2024

Abstract. Satellite altimetry data are useful for monitoring water surface dynamics, evaluating and calibrating hydrodynamic models, and enhancing river-related variables through optimization or assimilation approaches. However, comparing simulated water surface elevations (WSEs) using satellite altimetry data is challenging due to the difficulty of correctly matching the representative locations of satellite altimetry virtual stations (VSs) to the discrete river grids used in hydrodynamic models. In this study, we introduce an automated altimetry mapping procedure (AltiMaP) that allocates VS locations listed in the HydroWeb database to the Multi-Error Removed Improved Terrain Hydrography (MERIT Hydro) river network. Each VS was flagged according to the land cover of the initial pixel allocation, with 10, 20, 30 and 40 representing river channel, land with the nearest single-channel river, land with the nearest multi-channel river and ocean pixels, respectively. Then, each VS was assigned to the nearest MERIT Hydro river reach according to geometric distance. Among the approximately 12 000 allocated VSs, most were categorized as flag 10 (71.7 %). Flags 10 and 20 were mainly located in upstream and midstream reaches, whereas flags 30 and 40 were mainly located downstream. Approximately 0.8 % of VSs showed bias, with considerable elevation differences (≥|15| m) between the mean observed WSE and MERIT digital elevation model. These biased VSs were predominantly observed in narrow rivers at high altitudes. Following VS allocation using AltiMaP, the median root mean square error of simulated WSEs compared to satellite altimetry was 7.86 m. The error rate was improved meaningfully (10.6 %) compared to that obtained using a traditional approach, partly due to bias reduction. Thus, allocating VSs to a river network using the proposed AltiMaP framework improved our comparison of WSEs simulated by the global hydrodynamic model to those obtained by satellite altimetry. The AltiMaP source code (https://doi.org/10.5281/zenodo.7597310, Revel et al., 2023a) and data (https://doi.org/10.4211/hs.632e550deaea46b080bdae986fd19156, Revel et al., 2022) are freely accessible online, and we anticipate that they will be beneficial to the international hydrological community.

Abstract. Rock fractures are a key contributor to a broad array of Earth surface processes due to their direct control on rock strength as well as rock porosity and permeability. However, to date, there has been no standardization for the quantification of rock fractures in surface process research. In this work, the case is made for standardization within fracture-focused research, and prior work is reviewed to identify various key datasets and methodologies. Then, a suite of standardized methods is presented as a starting “baseline” for fracture-based research in surface process studies. These methods have been shown in pre-existing work from structural geology, geotechnical engineering, and surface process disciplines to comprise best practices for the characterization of fractures in clasts and outcrops. This practical, accessible, and detailed guide can be readily employed across all fracture-focused weathering and geomorphology applications. The wide adoption of a baseline of data collected using the same methods will enable comparison and compilation of datasets among studies globally and will ultimately lead to a better understanding of the links and feedbacks between rock fracture and landscape evolution.
Late Miocene to Early Pliocene benthic foraminifera from the Tasman Sea (International Ocean Discovery Program Site U1506)

Published: January 2024

Abstract. Modern and fossil benthic foraminifera have been widely documented from New Zealand, but detailed studies of material collected from drilling expeditions in the Tasman Sea are scarcer. This study aims to provide an updated taxonomic study for the Late Miocene–Early Pliocene benthic foraminifera in the Tasman Sea, with a specific focus on the paleoceanographic phenomenon known as the Biogenic Bloom. To achieve these goals, we analysed 66 samples from International Ocean Discovery Program (IODP) Site U1506 located in the Tasman Sea and identified a total of 98 taxa. Benthic foraminifera exhibit good preservation, allowing for accurate taxonomic identification. The resulting dataset serves as a reliable and precise framework for the identification and classification of the common deep-water benthic foraminifera in the region. The paleobathymetric analysis based on depth-dependent species indicates deposition at lower bathyal depths. Additionally, the quantitative analysis of the benthic foraminiferal assemblages allowed us to explore their response to the Biogenic Bloom at Site U1506. The paleoenvironmental analysis, focused on the Early Pliocene part of the Biogenic Bloom, points to high-productivity conditions driven by phytoplankton blooms and intensified vertical mixing of the ocean waters. These results provide valuable insights into the paleoceanographic events in the Tasman Sea, particularly the Biogenic Bloom, highlighting the significance of benthic foraminifera as reliable proxies for deciphering paleoenvironmental conditions. The taxonomic identifications and paleoenvironmental interpretations presented herein will aid in future paleoceanographic studies and facilitate comparisons with other deep-sea regions.

Abstract. This paper shows the results of the analysis on the first systematic dataset of flood episodes referred to the entire Pyrenees massif, named PIRAGUA_flood, which covers the period 1981–2015 (available at http://hdl.handle.net/10261/270351). First, the structure of the database is detailed, so that it can be reproduced anywhere else in the world adapting to the specific nature of each situation. Subsequently, the paper addresses the spatial and temporal distribution of flood episodes and events (including trends) that affected the Pyrenees regions of Spain (Catalonia, Aragon, Navarre, the Basque Country), France (Nouvelle Aquitaine, Occitanie) and Andorra, as well as the massif as a whole, for a given period of time. In the case of the Spanish regions, it was also possible to analyse the compensation paid out made by the Spanish Insurance Compensation Consortium, and the number of deceased. The weather types associated with flood episodes were also classified based on sea level pressure and 500 hPa geopotential height from ERA5. The results show 181 flood events and 154 fatalities, some of which affected more than one region. In the Spanish part of the Pyrenees, between 1996 and 2015, there were a total compensation payout amounting to € 142.5 million2015. The eastern part of the area records more flood events than the western one, being Catalonia the community that registered the highest number of events, followed by Andorra and Occitanie. Associated weather types are dominated by southern component flow over the Pyrenees region, with a thalweg on the Iberian Peninsula and a depression in the vicinity, either in the Atlantic or in the Mediterranean. In terms of the entire massif, there is a slight positive trend of 0.84 events/decade, driven by the evolution of ordinary and extraordinary floods, but not significant at 95 %. At a regional level, flood behaviour is more heterogeneous, although not significant for the most part. Nouvelle Aquitanie is the only region that shows a positive and significant trend of 0.34 events/decade.

Abstract. In this work, we study a Mediterranean cyclone, Helios, which took place during 9–11 February 2023 in the southeastern part of Sicily and Malta, by a multiparametric approach combining microseism results with sea state and meteorological data provided by wavemeter buoy, HF radar, hindcast maps and satellite SEVIRI images. The sub-tropical system Helios caused heavy rainfall, strong wind gusts and violent storm surges with significant wave heights greater than 5 m. We deal with the relationships between such a system and the features of microseism (the most continuous and ubiquitous seismic signal on Earth) in terms of spectral content, space–time variation of the amplitude and source locations tracked by means of two methods (amplitude-based grid search and array techniques). By comparing the location of the microseism sources and the area affected by significant storm surges derived from sea state data, we note that the microseism location results are in agreement with the real position of the storm surges. In addition, we are able to obtain the seismic signature of Helios using a method that exploits the coherence of continuous seismic noise. Hence, we show how an innovative monitoring system of the Mediterranean cyclones can be designed by integrating microseism information with other techniques routinely used to study meteorological phenomena.

Published: January 2024

Abstract. Remote sensing extraction of glacial lakes is an effective way of monitoring water body distribution and outburst events. At present, the lack of glacial lake datasets and the edge recognition problem of semantic segmentation networks lead to poor accuracy and inaccurate outlines of glacial lakes. Therefore, this study constructed a high-resolution dataset containing seven types of glacial lakes and proposed a refined glacial lake extraction method, which combines the LinkNet50 network for rough extraction and simple linear iterative clustering (SLIC) dense conditional random field (DenseCRF) for optimization. The results show that (1) with Google Earth images of 0.52 m resolution in the study area, the recall, precision, F1 score, and intersection over union (IoU) of glacial lake extraction based on the proposed method are 96.52 %, 92.49 %, 94.46 %, and 90.69 %, respectively, and (2) with the Google Earth images of 2.11 m resolution in the Qomolangma National Nature Reserve, 2300 glacial lakes with a total area of 65.17 km2 were detected by the proposed method. The area of the minimum glacial lake that can be extracted is 160 m2 (less than 6×6 pixels). This method has advantages in small glacial lake extraction and refined outline detection, which can be applied to extracting glacial lakes in the high-Asia region with high-resolution images.

La amiloidosis AL es una enfermedad debida al depósito, en órganos y tejidos, de fibrillas formadas por cadenas livianas producidas de forma patológica por plasmocitos clonales. Su tratamiento actualmente está orientado a erradicar el clon de células plasmáticas; este históricamente se extrapoló de tratamientos disponibles y estudiados para otras discrasias sanguíneas.En el año 2020, el Grupo de Estudio de Amiloidosis (GEA) confeccionó distintas guías de práctica clínica para el tratamiento de la amiloidosis AL.Desde entonces se han publicado ensayos clínicos que arrojan contundencia al conocimiento disponible hasta el momento, y están en desarrollo nuevas líneas de investigación que robustecen y estimulan el estudio en el área. En esta revisión se realiza una actualización de las guías existentes en lo que respecta al tratamiento de la amiloidosis por cadenas livianas.Como evidencia de relevancia, en el último año estuvieron disponibles resultados de ensayos clínicos que respaldan el uso de esquemas basados en daratumumab (un anticuerpo monoclonal anti-CD38+) para pacientes con diagnóstico reciente de amiloidosis AL como primera línea. Además, para el tratamiento de la amiloidosis AL refractaria o recaída, la disponibilidad de bibliografía respaldatoria es escasa y extrapolada del tratamiento del mieloma múltiple; sin embargo, actualmente existe evidencia de calidad para recomendar el uso de ixazomib, un inhibidor de proteosoma reversible por vía oral disponible en la Argentina desde 2020.Por último, se mencionan algunas líneas de investigación con otros anticuerpos monoclonales y terapéuticas basadas en el uso de CAR-T cells.

Authors: Krentel H , Naem A , Tannapfel A , Devassy R , Constantin A.S. , De Wilde R.L.
Published: January 2024

Background: Endometriosis is a chronic inflammatory oestrogen-dependent disease. It is characterised by elevated inflammatory markers in the peritoneal milieu with subsequent adhesiogenesis. Nowadays, excisional, and ablative surgeries are considered the main treatment of endometriosis, and adhesiolysis is being performed almost routinely during these procedures. Postoperative adhesion formation is a significant concern for many surgeons, especially as endometriosis patients are assumed to be predisposed to adhesiogenesis. In order to minimise adhesiogenesis after endometriosis surgery, the usage of different barrier methods have been discussed in the literature. Recent studies aim to investigate the effect of potato starch preparations on adhesion formation in endometriosis patients.

Objectives: We aim to describe the findings of a second-look laparoscopy on patients who received a starch-based anti-adhesive agent.

Materials and Methods: We present a retrospective case series that included the medical, surgical, and histopathologic data of three patients.

Main Outcome Measures: Intraperitoneal adhesion formation and peritoneal inflammation.

Results: All three patients had de-novo adhesions during the second-look laparoscopy. Pathological examination revealed noncaseating granulomatosis of the peritoneum in all patients.

Conclusion: The use of potato starch-based agents as a peritoneal adhesion prophylaxis in laparoscopic endometriosis surgery could lead to granulomatous peritoneal inflammation. Correct application by avoiding powder remnants through complete rinsing and transformation to gel seems to be an important factor to avoid this adverse effect.

What is new? We aim to highlight that potato starch-based anti-adhesive agents similar to the one used in this study could be a cause of adhesiogenesis and peritoneal inflammation.

Psoriasis vulgaris is a significant health problem and up to 30% of the patients are most likely to develop psoriatic arthritis. Secukinumab, an interleukin-17A (IL-17A) inhibitor, is used to treat patients with moderate-to-severe plaques associated with psoriatic arthritis. The aim of this case report was to highlight the efficacy of secukinumab treatment in a patient with both psoriasis vulgaris and psoriatic arthritis focusing the how to balance the benefits and adverse effects. A 36-year-old female came to Dr. Zainoel Abidin Hospital, Banda Aceh, Indonesia with chief complaint of itchy and scaly red plaques almost all over the body. The patient also experienced pain in both knees, both ankle joints and index finger as well as thumb in the right hand in the last year. The patient was diagnosed with psoriasis vulgaris and psoriatic arthritis, then treated with phototherapy and 15 mg of oral methotrexate each week for four weeks. Due to no improvement of the initial treatment, the patient received emollient and secukinumab at a dose of 300 mg/week subcutaneously for five weeks. The lesions began to disappear and the joint pain began to relieve. Secukinumab therapy was continued with a dose of 300 mg/month for six months. However, after six months, the patient complained of acnes appeared on the face. Therefore, the maintenance dose of secukinumab was decreased to 150 mg/month. After the reduced maintenance therapy was given, the patient came back with no complained of acnes. The erythematous plaques on trunk, back, arms and legs have subsided, as well as the joint pain. This case highlights that in a moderate-to-severe psoriasis associated with psoriatic arthritis, secukinumab is highly effective. However, since the potential adverse effects, education and regular follow-up are needed to analyze the success of the treatment and to be able to manage the adverse effects.

The purpose of the research is to determine the sensitivity and specificity of the developed test system in the immunofluorescence reaction as one of the methods for diagnosing Trypanosoma evansi. The novelty of the test system is the use of a local trypanosome isolate, which will increase the diagnostic value and specificity, with further production in accordance with international GMP standards, which will guarantee the quality and safety of the studies. The work used parasitological research methods and serological methods of setting the reaction of immunofluorescence in various concentrations. As a result of the studies, the high sensitivity and specificity of the fluorescence reaction in relation to the Trypanosoma evansi strain was confirmed. Diagnostic immunoglobulin is highly sensitive to trypanosomes at concentrations of 1:1 and 1:10 in green-yellow and blue-violet spectra. The specificity of the diagnostic immunoglobulin was confirmed by the absence of reaction with the blood cells of horses, as well as with the T. equiperdum strain, in which luminescence is visible only in the shell and undulating membrane. The use of the developed test system shows the potential of the immunofluorescence reaction in modern practical veterinary serology and parasitology, and will also contribute to the fight against equine trypanosomiasis in the Republic of Kazakhstan.

Genotyping of Kazakh milk camel Camelus dromedarius (n = 18) and meat camel Camelus bactrianus (n = 18) by loci for alpha S1 and kappa casein genes using PCR-RFLP technique has been conducted. Authors proposed new pair of PCR primers for amplification of fragment of CSN3 gene with subsequent digestion of reaction products by AluI endonuclease restriction enzyme to identify genetic variations in the gene. DNA polymorphism at kappa casein gene has been detected whereas. A large discrepancy between the actual distribution of the genotype according to the kappa-casein locus with the theoretical distribution has been established for camels of dromedar and bactrian breeds. There is an excess of TT and CC homozygotes (16 versus 14.2 theoretically expected, 2 versus 0.2 theoretically expected, respectively) and a lack of TC heterozygotes (0 versus 3.6 theoretically expected). If the empirical and theoretical distribution of genotypes have the same value then the chi-square index is zero. As the difference between observed and expected numbers increases, the chi-square value increases. At the second gene, alpha S1, no polymorphism has been observed. Genotyping data performed on two Kazakh camel breeds by allele analysis at alpha S1 and kappa casein gene loci and by DNA fingerprinting suggest that individuals of former camel breed were more genetically polymorphic that those of later one.

“The Missing Mum Mystery”: Solved
Authors: Phillips Patrick
Published: January 2024

For decades, collectors and museum curators have pondered the meaning behind the defacing or removal of Imperial chrysanthemum seals on Japanese rifles following the surrender of Japan in 1945. Several myths and explanations for the removal are commonplace and have been perpetuated since the end of the Second World War, but definitive evidence explaining exactly why the chrysanthemum was removed has not been presented in the English language until recently. The truth of the matter lies with the disarmament of Japan, Japanese ordnance regulations, and perceived requirement of removal by American servicemembers. All Japanese rifles since the 1880s were marked with the chrysanthemum, and it is common to find examples of various models of rifle with the chrysanthemum intact, whilst other examples of the same model have had the seal removed or mutilated. This article presents evidence which proves that the Japanese did indeed order the removal of the Imperial chrysanthemum and that this had been an established practice decades before the Second World War.

Soil compaction poses a significant challenge to modern agriculture, negatively impacting soil productivity and crop yields. This article reviews current research on non-destructive techniques for identifying soil compaction and evaluates their effectiveness in understanding its impact on agricultural output. Sustainable practices are explored, focusing on non-destructive methods like soil penetrometry, ground-penetrating radar (GPR), remote sensing, and geophysical approaches. The study emphasizes the advantages of non-destructive technologies over traditional invasive methods, allowing immediate assessment without compromising soil integrity. Case studies demonstrate the practical application of these techniques in diverse agricultural environments, showcasing their ability to detect and manage soil compaction. The literature review underscores the importance of promptly and accurately identifying soil compaction to implement effective management measures. Results and interpretations from relevant research highlight the effects of compaction on root development, water permeation, nutrient accessibility, and overall agricultural productivity. Real-world case studies and tables visually depict non-destructive techniques, measurement parameters, and the correlation between soil attributes and crop productivity. The discussion delves into the limitations of non-destructive procedures, emphasizing the need for calibration against conventional methods for precision. The article stresses the significance of non-destructive practices in promoting sustainable agriculture. Proposed actions include further studies to refine and establish these techniques, comparative analyses across different soil types and crops, and the development of user-friendly software for incorporating non-destructive data into agricultural practices. The integration of non-invasive methods into routine soil monitoring is seen as a key strategy to enhance the resilience and productivity of agricultural systems, fostering environmentally friendly farming methods.

(2) teachers' perceptions of learning implementation are not very positive because most teachers are still not optimal in implementing the learning process as required by the Independent Curriculum; and (3) teachers' perceptions of learning evaluation are good. Teachers recognize the significance of assessment in the Merdeka Curriculum. Teachers have employed a range of evaluation techniques, including observations, performance assessments, written tests, oral exams, and portfolios. Based on these findings, teachers should conduct a thorough analysis of the Merdeka Curriculum's implementation. Teachers must think openly when adopting the Independent Curriculum to ensure future adjustments and improvements.

Authors: Pham The Ky , Tran Phu Ngoc , Vo Hong Duc
Published: January 2024

Purpose – The importance of corporate governance and intellectual capital on financial performance has largely been ignored in emerging markets. The banking sector is considered to accumulate a higher level of intellectual capital and to adopt a better corporate governance system. We aim to examine the contribution of these two important aspects to the performance of Vietnam's banking sector.
Design/methodology/approach – This paper utilizes data collected from the annual reports of banks in Vietnam from 2011 to 2021. The modified value-added intellectual coefficient (MVAIC) model is adopted to measure a bank's intellectual capital efficiency. In addition, the generalized method of moments is utilized to ensure the robustness of the findings.
Findings – Empirical results strongly confirm that intellectual capital positively contributes to a bank's performance. In terms of corporate governance, the findings indicate that board size, board remuneration and major shareholders holding more than 20 percent of outstanding shares are the three most important factors that contribute positively to banks' performance. In addition, human capital efficiency and capital employed efficiency positively impact a bank's profit.
Practical implications – Our study provides valuable evidence and implications for policymakers in managing and enhancing corporate governance and intellectual capital efficiency within the Vietnamese context, particularly in the banking sector.
Originality/value – To the best of our knowledge, this is the first empirical paper conducted to examine the contribution of corporate governance and intellectual capital on banks’ performance in Vietnam.

E-payment services have witnessed a surge in demand in recent years due to their convenient cashless transaction mode. Several studies have investigated the influence of the intention of individuals to use mobile wallets. However, the study aims to examine the key factors that impact students’ intention to use E-payment services in Ho Chi Minh City, Vietnam. The Technology Acceptance Model combines two factors from the extended version of TAM including perceived convenience and trust to develop a conceptual model for this study. The online survey of 310 students from some universities collected the data and the Smart PLS was used to analyze the data. The results of the study showed that perceived ease of use, perceived usefulness, trust, and perceived convenience have a positive influence on behavioral intention to use mobile wallets, while trust shows no positive effect on perceived usefulness.

X memiliki beberapa pembangkit diantaranya Pembangkit Listrik Tenaga Uap (PLTU), dan Pembangkit Listrik Tenaga Gas dan Uap (PLTGU), dengan total daya terpasang 2219 MW. Pompa sentrifugal CN 80-32 pada unit PLGU PT. X digunakan untuk mengalirkan fluida dari Daerator menuju HRSG melalui econoimaizer. Dalam optimalisasi unjuk kerja pompa parameter yang dibutuhkan antara lain kapasitas, head pompa, daya, efesiensi, dan NPSHa. Data tersebut didapatkan melalui data sheet dan manual book. Hasil dari perhitungan setelah dievaluasi maka dapat dilihat bahwa kapasitas mengalami penurunan setelah perubahan kecepatan putaran senilai 61,73 m3/hr dari kapasitas aktual 65,9 m3/hr. Kemudian head aktual mengalami kenaikan sebesar 141,77 m dari head desain 124,5 m, lalu ketika dioptimalisasi terjadi penurunan dari semula 141,77 m menjadi 124,42 m. Selain itu daya poros pompa juga mengalami penurunan dengan nilai 35,26 kW dari daya aktual 42,89 kW. Namun, efisiensi pompa setelah dioptimalisasi mengalami kenaikan sebesar 66 % yang mana pada saat perhitungan aktual efisiensi pompa turun senilai 55 %. Hal ini sebabkan karena penurunan kecepatan putaran 2803 rpm dari kondisi rpm aktual dengan nilai 2992 rpm. Perununan kecepatan putaran tersebut didapatkan dengan menggunakan inverter

Perusahaan Hulu Migas mematuhi persyaratan dalam melakukan pengadaan barang APDNkategori wajib, sehingga sebelum melakukan pengadaan harus melakukan pengecekan barang padalaman buku APDN yang sudah diterbitkan oleh Kementerian ESDM, jika barang yang dibutuhkan tidakterdaftar dalam buku APDN maka persyaratan dari pengadaan barang tersebut ialah ber-TKDN 0% dandapat diimpor meskipun barang tersebut sudah diproduksi di dalam negeri. Hal ini terjadi dikarenakanuntuk produk dengan nilai TKDN diatas 25% diharuskan untuk membeli barang yang sudah terdaftar di buku APDN. Upaya pendaftaran barang penunjang sektor migas pada buku APDN dilakukan agar dapat dimaksimalkan, dengan hal itu nilai TKDN yang awalnya 0% berpotensi meningkat menjadi 57%setelah dihitung menggunakan Weighted Average sebagai metode untuk upaya peningkatan pengadaan barang yang memiliki nilai TKDN. Keuntungan lain dari pengadaan barang wajib/APDN adalah proses pengadaan lebih cepat sehingga fungsi user lebih cepat memperoleh barang untuk kelangsungan operasional, dibuktikan dari data pengadaan di PT. ABC yang mendapatkan rata-rata pengadaan Barang APDN dilakukan selama 38 hari kerja dan 50 hari kerja untuk Pengadaan Non-APDN, sehingga berpengaruh pula pada biaya tender, jika satu harinya dibiayai Rp 1.000.0000, maka untuk pengadaan Barang Non-APDN menghabiskan biaya tender Rp 50.000.0000 sedangkan pengadaan Barang APDN hanya memerlukan biaya sebesar Rp 38.000.000.
