Published: November 2023

AbstractThis article presents the development of the site characterization database for the 2022 New Zealand National Seismic Hazard Model update. This database summarizes the site characterization parameters at past and present GeoNet seismic monitoring network instrument locations, including strong-motion, short-period, and broadband seismometer stations. Site characterization parameters required to assess and improve empirical ground-motion models and those used in codified seismic design frameworks internationally have been included in the database. Measurement uncertainty was assigned, and the quality of the data used to assign each parameter was classified. The site period (T0) was the most well constrained of all the site parameters, with almost half of the database classified based on high-quality measurements, with these dominated by microtremor-based horizontal-to-vertical spectral ratio. Although there was an improvement in the quality of the parameters representing the time-averaged shear-wave velocity in the uppermost 30 m of the profile (VS30), little site-specific data were available, with almost no information for rock sites. Most of these classifications were based on national maps or geologic interpretation. Depth-based parameters (Z1.0 and Z2.5) had the lowest quality overall, with very few direct measurements available to constrain these values. Despite these limitations, the quality of parameters assigned to instrument locations has improved and greatly expanded previous databases through the assignment of parameter values to the entire GeoNet seismic network.
The Earthquake of 13 April 1850 near Ston, Croatia: Macroseismic Analyses
Authors: Herak Davorka , Herak Marijan , Vrkić Iva 
Published: November 2023

Abstract
The earthquake that occurred near the city of Ston, Croatia, on 13 April 1850 is, together with the one from 1996, the strongest known event in the northwest part of the Dubrovnik epicentral area. This is the region with the highest seismic hazard in Croatia with a rich history of damaging earthquakes. Although listed in the relevant catalogs, this earthquake has never been addressed by a dedicated study. Herewith, we present analyses of a wealth of newly found material related to the damage and postearthquake actions of the authorities of the Province of Dalmatia, then a part of the Austrian Empire. We were able to estimate intensity at five localities, with a further six where the data were sufficient only to constrain the minimum intensity value. By far, most of the data refer to Ston and Dubrovnik. Intensity data points were inverted for the source parameters by two different methods, each of which yielded similar results. The focus is macroseismically located about 7 km east-southeast from Ston, at a depth of 9 km. Estimated epicentral intensity of 8.2 on the European macroseismic scale is equivalent to macroseismic local magnitude MmL=6.0 or the moment magnitude Mmw=5.9. The location of focus and the epicentral intensity are practically identical to those of the Ston–Slano earthquake of 1996. This is why we propose that these two earthquakes share the same composite seismogenic source consisting of a set of imbricated mostly reverse faults related to the basal thrust of the Dalmatian tectonic unit. The reliable location and quantification of the 1850 earthquake should contribute to a better understanding of the active dynamics of the set of large seismogenic faults in the Dubrovnik epicentral area.

Background: Recent advances in microbiome sequencing techniques have provided new insights into the role of the microbiome on human health with potential diagnostic implications. However, these developments are often hampered by the presence of a large amount of human DNA interfering with the analysis of the bacterial content. Nowadays, extensive scientific literature focuses on eukaryotic DNA depletion methods, which successfully remove host DNA in microbiome studies, even if a precise assessment of the impact on bacterial DNA is often missing.
Methods: Here, we have investigated a saponin-based DNA isolation protocol commonly applied to different biological matrices to deplete the released host DNA.
Results: The bacterial DNA obtained was used to assess the relative abundance of bacterial and human DNA, revealing that the inclusion of 2.5% wt/vol saponin allowed the depletion of most of the host’s DNA in favor of bacterial DNA enrichment. However, shotgun metagenomic sequencing showed inaccurate microbial profiles of the DNA samples, highlighting an erroneous increase in Gram-positive DNA. Even the application of 0.0125% wt/vol saponin altered the bacterial profile by depleting Gram-negative bacteria, resulting in an overall increase of Gram-positive bacterial DNA.
Conclusion: The application of the saponin-based protocol drastically changes the detection of the microbial composition of human-related biological specimens. In this context, we revealed that saponin targets not only host cells but also specific bacterial cells, thus inducing a drastic reduction in the profiling of Gram-negative bacterial DNA.
Seismic fingerprint predicts ground motions during the 2018 Kilauea collapse sequence
Authors: Johnson Christopher , Johnson Paul 
Published: November 2023

Abstract
Continuous acoustic emissions from laboratory earthquake faults and slowly-slipping subduction zone faults, signals previously deemed to be dominantly noise, are rich with physical details including the fault displacement and friction. However, no evidence currently exists demonstrating that the hidden signals observed in the laboratory and subduction slow-slip occur during seismogenic stick-slip on earthquake faults-the damaging earthquakes of most societal interest. Here, we show that seismic emissions associated with the 2018 caldera collapse at the Kilauea volcano in Hawai'i contain hidden signatures of instantaneous surface displacement and the time-to-failure of the upcoming collapse event. This striking result suggests that at least some faults in Earth emit such signals and provide a potential path to characterizing the instantaneous and future behavior of earthquake faults.

Abstract
Despite advancements in B-cell acute lymphoblastic leukemia (B-ALL) therapy, a significant number of patients still experience treatment resistance, leading to relapse and poor prognosis. Recent studies have revealed the importance of non-genetic mechanisms in mediating resistance to cancer therapies. MicroRNAs (miRNAs) have emerged among non-genetic mechanisms as crucial regulators of tumor development, progression, and resistance to anticancer therapies. In particular, miR-34a has been implicated in cell invasion, migration, apoptosis, and abnormal response to chemotherapy in various tissues. However, the role of miR-34a-5p in B-ALL cells remains unexplored. Our results discovered that miR-34a-5p was downregulated in B-ALL cells, while its target SIRT1 was upregulated. Although the restoration of miR-34a-5p levels did not affect SIRT1 levels in B-ALL cells, restoring miR-34a-5p sensitized the cells to doxorubicin treatment. Additionally, to explain these results, we performed an extensive bioinformatic analysis in human B-ALL samples downloaded from online repositories to study miR-34a-5p as a potential biomarker for predicting response to B-ALL treatment. Notably, miR-34a-5p was found to be downregulated in B-ALL cells from relapsed patients. We also identified four genes targeted by miR-34a-5p in these patient cells, which had not been previously associated with B-ALL. Finally, miR-34a-5p, PRR11, and SURF4 were identified as independent predictive markers for increased risk of death in B-ALL patients. Overall, these findings shed light on the significance of miR-34a-5p in B-ALL cells, and suggest that the combination of miR-34a-5p, PRR11, and SURF4 hold promise as potential markers for estimating the survival outcomes of B-ALL patients.

Abstract

Pollinator-driven evolution of floral traits is thought to be a major driver of angiosperm speciation and diversification. The bee orchids (genus Ophrys) mimic their pollinators’ female pheromone, shape and colour to lure male pollinators into pseudocopulation. This strategy, called sexual deception, is highly species-specific, thereby providing strong premating reproductive isolation. Identifying the genomic architecture underlying pollinator adaptation and speciation may shed light on the mechanisms of angiosperm diversification. We report the 5.2 Gb chromosome-scale genome sequence of Ophrys sphegodes and show that chromosomal rearrangements took place in the Ophrys lineage. We find evidence for a transposable element expansion event that preceded the radiation of the O. sphegodes group, and for gene duplication having contributed to the evolution of chemical mimicry. Moreover, one region on chromosome 2 is highly differentiated between O. sphegodes and other Ophrys species, indicating a candidate genomic region for pollinator-mediated evolution.

Abstract

Laser-based light detection and ranging (LIDAR) offering a powerful tool to real-timely map spatial information with exceptional accuracy, owns various applications ranging from industrial manufacturing, remote sensing, to airborne and in-vehicle missions. Over the past two decades, the rapid advancements of optical frequency combs have ushered in a new era for LIDAR, promoting measurement precision to quantum noise limited level. For comb LIDAR systems, to further improve the comprehensive performances and reconcile inherent conflicts between speed, accuracy, and ambiguity range, innovative demodulation strategies become crucial. Here we report a dispersive Fourier transform (DFT) based LIDAR method utilizing phase-locked Vernier dual soliton laser combs. We demonstrate that after in-line pulse stretching, the delay of the flying pulses can be identified via the DFT-based spectrally interferometric measurement instead of pulse-fitting in time domain. This enables absolute distance measurements with precision starting from 262 nm in single shot, to 2.8 nm after averaging 1041 times, in a non-ambiguity range over 1.7 km. Furthermore, our DFT-based LIDAR method distinctly demonstrates an ability to completely eliminate dead zones. Such an integration of frequency-resolved ultrafast analysis and dual comb ranging technology may pave a way for the design of future LIDAR systems.

Abstract

The human retina serves as a crucial interface for converting light into neural signals and its microvasculature reflects the health of the vascular system. Optical coherence tomography angiography (OCTA) has revolutionized retinal vascular imaging, offering noninvasive, high-resolution visualization. However, challenges persist in the trade-off between the FOV and resolution as well as the low contrast of microvascular, particularly for deeper retinal layers. To address these issues, we developed a complex variance (CV) OCTA system with an ultra-high A-line rate and phase stability based on the phase-locked time-stretch OCT technique. Leveraging a dual-chirped fiber Bragg grating architecture, our system achieves an exceptional 5-MHz A-line rate, sub-nanometer phase stability, and a remarkable 2-mm imaging depth. Our system demonstrated superior spatial resolution compared to commercial OCTA systems, facilitating high-contrast imaging of the foveal avascular zone and deep vascular complex. This technology holds promise for detecting and monitoring retinal and systemic diseases, such as age-related macular degeneration, glaucoma, diabetic retinopathy, and even Alzheimer's disease, thus advancing our understanding of vascular health. This study's findings emphasize the clinical relevance and potential impact of CV OCTA in the field of retinal imaging.

Published: November 2023

Abstract
Aim
This retrospective study aimed to determine whether different renal function estimation formulas affect the incidence of venous thromboembolism (VTE) and bleeding when anticoagulant dosages were determined.
Methods
The study included patients who underwent lower-limb orthopedic surgery and were treated with anticoagulants between January 2017 and March 2020 at Yaizu City Hospital. The appropriateness of anticoagulant dosing was assessed using creatinine clearance (CCr) and estimated glomerular filtration rate (eGFR), and the incidence of VTE and bleeding was compared among the different renal function estimation formulas.
Results
The median values for body surface area, CCr, and eGFR were 1.40m2, 56.0mL/min, 73.0mL/min/1.73m2, respectively. There was no significant difference in the incidence of VTE among the different renal function estimation formulas. However, when the threshold for dose reduction or contraindication was determined by eGFR rather than CCr, the incidence of bleeding was significantly higher in the group that was overdosed in CCr (6.0% vs 25.7% p < 0.05).
Conclusion
It is necessary to set the dosage of anticoagulants based on CCr for patients with a small body surface area in the field of orthopedics to avoid the risk of bleeding.
Study on the Mechanical Properties and Dynamic Constitutive Relationship of Ceramsite Concrete Affected by Freeze-Thaw Cycling

Published: November 2023

Abstract
In this study, the dynamic and static mechanical properties as well as the internal microstructure (capillary porosity) and constitutive relationship of sulphoaluminate ceramsite concrete with a ceramsite volume fraction of 40% are examined under freeze-thaw cycling. The results reveal that an increase in the number of freeze-thaw cycles or a decrease in the lowest temperature of the freeze-thaw cycle leads to a decline in the compressive strength and performance, causing enlargement of pores in the ceramsite concrete. During the freeze-thaw cycles, the internal pores in the ceramsite concrete expand outward due to water freezing and expansion. In dynamic compression tests, the transition zone between ceramsite and matrix within the ceramsite concrete is the most susceptible to cracking and damage, forming a distinct primary crack. Industrial computed tomography (CT) scanning results demonstrate that both impact compression and freeze-thaw cycling exacerbate the internal damage in concrete. The expansion of internal pores in the concrete during freeze-thaw cycles is closely related to the lowest temperature T*, the number of freeze-thaw cycles N, and the expansion factor k of freeze-thaw pores. In conjunction with experimental analysis, a constitutive relationship is proposed that accounts for the effects of freeze-thaw cycling on the damage behavior of ceramsite concrete.
Improved EEMD and overlapping group sparse second-order total variation

Abstract

Strong background noise increases the difficulty in extracting the early fault features of rolling bearing and leads to the signal waveform distortion problem of the total variation denoising method (TVD). Therefore, this paper presents an ensemble analysis method of fault features that combines improved ensemble empirical mode decomposition (MEEMD) with overlapping group sparse second-order total variation (OGSSTV). Based on typical vibration signals with background noise, the effects of mode mixing, reconstruction error, and noise reduction on MEEMD and OGSSTV methods were analyzed and the suitable parameters for fault feature extraction of vibration signals were determined. On this basis, the proposed method was used to extract motor bearing fault features. Simulation results and experimental data showed that the proposed method could suppress mode mixing, reduce the reconstruction error, and solve the waveform distortion problem caused by TVD in the process of signal noise reduction.
