Authors: Ochai-Audu Eudorah 
Published: March 2023

The energy transition and disruption in the energy supply/demand chains fueled by the combined effect of the COVID-19 pandemic and the ongoing Russia/Ukraine war have given rise to more-innovative geoscience approaches geared toward carbon-footprint reduction with efficient and sufficient energy supply despite the increasing difficulty in finding new or remaining hydrocarbon accumulations.
This year’s titles have a good mix of new frontier exploration, expanding heartlands, and brownfield-development themes. Improved seismic survey techniques, seismic image uplift, enhanced seismic attribute analysis, reservoir characterization, fracture diagnostics, mitigation of induced seismicity, and carbon capture and storage topics also are featured.
As in previous years, more achievements in machine learning and automation of seismic processing and attribute analysis on both new or existing data to redefine geological plays, improve understanding of risks and uncertainties, enhance well placement and hydrocarbon recovery, reduce cost, and increase production are worthy of note.
The selected top three papers for synopsis and those recommended for reading provide a taste of the themes mentioned above. I hope you find them as informative and transformational as I did.

Abstract
To date, existing Siamese-based trackers have achieved excellent performance. However, in some complex scenarios, using deep convolutional layers alone can not effectively capture powerful representative features. To solve this problem, we propose a Siamese Attention and Deformable features fusion network for visual object Tracking (SiamADT). The proposed SiamADT consists of three modules: a Siamese attention network module for attention feature extraction, a deformable features fusion module, and a classification-regression module for bounding box prediction. Our framework uses ResNet-50 as the backbone to achieve anchor-free tracking. Without tricky hyperparameters tuning of anchors and human intervention, SiamADT is more flexible and versatile. We conduct extensive experiments on four challenging benchmark datasets. The results demonstrate that SiamADT achieves competitive performance among state-of-the-art methods, with real-time speed- 30 frames per second (FPS).
Turbulent Kinetic Energy Budget and Turbulent Bursting in a boulder concentrated permeable gravel bed stream
Authors: DAS RATUL , DATTA AKASH 
Published: March 2023

Abstract
Turbulent kinetic energy (TKE) budget distributions and turbulent bursting events are investigated to elucidate the physical process of energy balance among the different TKE-budget terms and turbulent bursting events within the arrays of immobile boulders placed on a gravel bed stream. In order to carry out the experimental investigations, the arrays of boulder at three different spacing were considered and an acoustic Doppler velocimetry (ADV) was employed to measure the flows along the centre-line transect of the flume. The measured data were analysed using double-averaging methodology (DAM). The experimental results reveal that the negative pressure energy diffusion rates in TKE-budget distributions at the vicinity of boulder wake flow region develops enhanced turbulence production rates corroborating the development of flow recirculation in the near-bed wake flow region. The measured TKE-fluxes in small spacing boulder arrays infers lesser magnitude in comparison to those over the medium and large spacing boulder arrays which reveal to our understanding that the collective form drag in small spacing boulder arrays caused partial reduction of TKE-fluxes by the flows. However, in the outer flow-region they are almost alike. According to the quadrant analysis, the sweep events are the prevailing events in the vicinity of the stream bed within the boulder arrays and above this a change over of the dominance from sweeps to ejections takes place for the remaining depth.
Assessing perceptions of environmental change among a climate change-illiterate population from Bangladesh
Authors: Freihardt Jan 
Published: March 2023

Abstract
Effective climate change adaptation requires a thorough understanding of whether and how affected populations perceive climatic and environmental changes. Existing research has been inconclusive regarding the consistency of these perceptions compared to objective meteorological indicators. Moreover, no systematic comparison has been done for the perception of discrete environmental events such as floods or erosion. This study relies on novel panel survey data of approximately 1700 households residing along the Jamuna River in Bangladesh as well as on unique individual-level, satellite-based erosion data. It compares respondents’ perceptions of environmental events, namely riverbank erosion, and three climate change indicators, specifically long-term temperature change and changes in precipitation during wet and dry seasons, to objective measurements using satellite imagery and climatic time-series data (CRU TS). The results suggest that erosion is strongly overestimated, especially by those respondents who had been personally affected by it. Long-term temperature change is perceived more accurately than long-term changes in precipitation. Given that educational attainment and climate change literacy among the study population are low, the findings indicate that global temperature increases are felt even by remote and uneducated populations who have never heard the term climate change. This has important policy implications since it suggests that knowledge and education about climate change are not a prerequisite for perceiving and potentially adapting to climatic changes.
Parameter Identification Problem in the Discrete-time Sir Model
Authors: VALLE JEMY A. MANDUJANO , Madureira Alexandre L. 
Published: March 2023

Abstract
We investigate the problem of determining time dependent parameters for discrete-time epidemiological compartmental models such as the Susceptible-Infected-Recovered (SIR). We show how to determine parameters based on minimal error type iterative schemes. Such methods involve the computation of the adjoint of the derivative operator of a nonlinear function. This is a nontrivial task that we accomplish by carefully crafting auxiliary problems. To show the efficiency of the method, we consider examples involving real COVID-19 data.
Oxidation state of bioavailable dissolved organic matter influences bacterioplankton respiration and growth efficiency

Published: March 2023

Abstract

Heterotrophic bacterioplankton use oxygen and dissolved organic matter (DOM) to acquire energy, carbon and nutrients necessary for growth; however, the impacts of the chemical composition of DOM on the ratio of oxygen uptake to carbon respiration (i.e., respiratory quotient, RQ) and bacterioplankton growth efficiencies (BGEs) are not well constrained, particularly for nutrient-limited regions such as open oceans. To investigate the influence of DOM composition on RQ we performed DOM remineralization bioassays over a senescing phytoplankton bloom in the eastern North Atlantic Ocean. We found that more oxidized DOM and nitrogen-containing compounds were utilized at lower BGEs and elevated RQs, which we hypothesized to be due to shifts in the energy yield per carbon atom. Results provide important new insights into the molecular mechanisms of the global carbon cycle and have implications for predicting the impacts of future warmer oceans on DOM utilization by bacteria.

Abstract

Major depressive disorder (MDD) in adolescence seriously endangers their mental and physical health and is associated with poor social and scholastic function. However, the diagnosis and therapeutic biomarkers for adolescent with MDD remain unclear. Differential expressions of lncRNAs and mRNAs of plasma exosome were screened from 10 adolescent MDD patients and 10 healthy controls by microarray, lncRNAs-miRNAs-mRNAs networks had been generated by bioinformatic analysis, especially, 3752 differential expressions of lncRNAs and 1789 differential expression of mRNAs were included. 2 sets of axes such as AC156455.1/miR-126-5p/AAK1 and CCDC18AS1/miR-6835-5p/CCND2 were picked from networks. Candidate lncRNAs, miRNAs and mRNAs were verified in 64 adolescent MDD patients (MDD group) and 30 healthy controls (HC group) using qRT-PCR. We found that six candidate genes were differential expression between MDD group and HC group, or before and after antidepressant treatment of MDD group. The expression levels of AAK1, CCDC18AS1 and miR6835 varied in efficacy after 8-week sertraline treatment. We also found that the expression of CCDC18AS1/miR-6835-5p/CCND2 axis at baseline could predicted sertraline efficacy, which may be mediated through reducing suicidal ideation and improving cognitive function. Our study identified and validated the plasma exosome- derived lncRNAs, miRNAs and mRNAs altered in adolescent with MDD, our findings provided potential diagnosis and therapeutic biomarkers for adolescent with MDD.
How do strokes affect the brain's critical state? Structural and functional aspects of the loss of connectome integrity

Published: March 2023

Abstract
This paper addresses the problem of the brain's critical behavior in the case of a brain injury such as a stroke. Employing network models to simulate the post-stroke brain, we demonstrate that an anomalous behavior of the critical characteristics, the second-largest cluster size, results from the loss of integrity of the network, quantified within the graph theory, and not from genuine non-critical behavior. Thus, even in a post-stroke state, the brain dynamics remain critical. The proposed interpretation of the results is confirmed with the analysis of the real connectomes acquired from post-stroke patients and the control group. The results presented refer to neurobiological data; however, the conclusions reached apply to a broad class of complex systems for which a critical state is identified.

Published: March 2023

Abstract

Background Literature related to minority stressors in affective symptoms among Lesbian, gay, and bisexual (LGB) students in China is sparse, and often limited to specific provinces. Methods A combination of snowball and targeted sampling strategies was used to recruit lesbian, gay and bisexual students (N = 1,393) for a cross-sectional, online survey in China. Participants (Mage = 20.00 years; 60.23% assigned male at birth) completed a questionnaire assessing gender expression, minority stressors (school bullying, internalized homophobia), social psychological resources (social support), and health related outcomes (depression, anxious and stress). Hierarchical multiple regression analyses and structural equation modelling (SEM) was employed to test associations among these factors, with social psychological resources as a mediator between minority stress and health. Results 48.1% of the LGB students had depression; anxiety and stress were 57.1%, 37.5% respectively. Minority stressors were negatively associated with perceived social support, which was negatively associated with affective symptoms. Beyond indirect effects of minority stress on affective symptoms, direct links was also found. Conclusions LGB experience large and serious health disparities, as do LGB students. There is, an urgent need for prevention and intervention activities for LGB students, and these needs diverge along gender lines.

Abstract

Objective To systematically evaluate the efficacy and safety of anlotinib for patients with metastatic colorectal cancer (mCRC). Method We searched eligible studies in PubMed, Embase, Cochrane Library, Wanfang Patent Database and China National Knowledge Infrastructure (CNKI) from database inception to September 3, 2022. A total of four random control studies were included to extract relevant data, including objective response rate (ORR), disease control rate (DCR) and the rate of adverse events. The Stata version 14.0 software was used to calculate the risk ratio (RR) with 95% confidence intervals (95% CI). Results This meta-analysis included 618 patients from four clinical studies. The pooled RR for ORR and DCR were 1.54 (95% CI: 1.08–2.20,P＜0.05) and 1.38 (95% CI: 1.04–1.81,P＜0.05), indicating that anlotinib administration significantly improved ORR and DCR in patients with mCRC. The pooled RR for the incidence of diarrhea was 1.64 (95% CI: 0.72–3.73,P = 0.24) and the rate of leukocytopenia was 2.32 (95% CI: 1.16–4.62,P＜0.05). Conclusion Anlotibin, an oral multi small-molecule receptor tyrosine kinase inhibitor, may provide clinical benefits for patients with mCRC in terms of ORR and DCR. Adverse events associated with anlotinib were tolerable.

Authors: Salleh Hazeqa Mohamed , Avoi Richard , Karim Haryati Abdul , Osman Suhaila , Kaur Nirmal , Dhanaraj Prabakaran 
Published: March 2023

Abstract
Background: The implementation outcomes determine the success and progress of a community-based intervention programme. The community is an important stakeholder whose effects should be assessed. Nevertheless, Malaysia has limited instruments for determining outcome measurements. This research aimed to develop Malay versions of the Acceptability, Appropriateness, and Feasibility Intervention Measures (AIM-IAM-FIM) questionnaire, which evaluates the implementation outcome of the programme.
Methods: A methodological study of the translation and validation of the implementation outcome measures was conducted from March 2023 until December 2023. Three key analyses were conducted: (1) translation and validation; (2) factor investigation and extraction (n = 170); and (3) scale evaluation (n = 235).
Result: The Malay version measuring the implementation outcome measures of a community-based intervention programme was produced after extensive translation and modification, and it consisted of a single dimension with seven items. The content validity index was 0.9, the exploratory factor analysis showed that the KMO measure of sample adequacy was 0.9277, and Bartlett’s sphericity test was statistically significant. Cronbach’s alpha was good, with a level of 0.938. The single factor structure fitted the data satisfactorily [χ2 (p-value of 0.002), SRMR = 0.030, CFI = 0.999, RMSEA = 0.079, TLI = 0.998]. Factor loading for all items was > 0.7.
Conclusion: The 7-item Malay version of the AIM-IAM-FIM survey instrument is valid and reliable for assessing the acceptability of a community-based intervention study and is applicable to other fields. Future studies in psychometric evaluation are recommended in other states due to the variety of Malay dialects spoken across Asia. The scale may also benefit other areas where the language is spoken.
Parenteral nutrition, sepsis, acute heart failure and hepatotoxic drugs are related to liver test disturbances in critically ill patients
Authors: Rosseel Zenzi , Cortoos Pieter-Jan , Jonckheer Joop , Cools Wilfried , Vinken Mathieu , Reynaert Hendrik , De Waele Elisabeth 
Published: March 2023

Abstract
Background and aims: In a clinical intensive care setting, parenteral nutrition (PN) is often associated with liver dysfunction although other contributing factors such as sepsis, acute heart failure (AHF) and hepatotoxic drugs can be present. This retrospective study aimed to identify the impact of these factors on liver test dysfunction with focus on PN.
Methods: Adult ICU patients admitted for ≥3 days and treated with PN for ≥ 3days were included. Liver test disturbances were recorded at day 1 of PN based on elevation of aspartate aminotransferase (AST), alanine aminotransferase (ALT) or alkalic phosphatase (AP). The presence of AHF, sepsis and 5 previously selected hepatotoxic drugs was recorded. Volume of PN, calorie abundance, amount of proteins, lipids and carbohydrates were monitored. A linear mixed-effect model was used to assess the contribution of PN, sepsis, AHF and drugs to liver test abnormalities. Nutritional adequacy was defined as the caloric, protein, lipid and carbohydrate intake compared to theoretical needs.
Results: Liver test abnormalities, presence of sepsis and AHF were the main confounders in predicting liver parameters in 224 ICU patients treated with at least 3 days PN. Presence of sepsis caused an average increase of 43% ± 7% for total bilirubin (TB), 36% ± 14% for gamma-glutamyltransferase (GGT) and 32% ± 8% for AP. Secondly, presence of AHF caused an increase of 29 ± 13% % for ALT and 75% ± 14% for AST. Volume of PN administrated caused an increase of 10% ± 5% for ALT and 14% ± 1% for AST. Carbohydrate intake exceeded nutritional recommendations and protein and lipid intake was not sufficient.
Conclusion: Liver test disturbances in critically ill patients on PN for at least 3 days have multifactorial associations with sepsis and AHF being the main confounders. Volume of PN and hepatotoxic drugs had a smaller impact. Feeding adequacy revealed opportunity for improvement by reducing carbohydrate and increasing lipid and protein content.
Effectiveness of Geometric Quality Control Using a Distance Evaluation Applied to an Ifsar Dem

Published: March 2023

Abstract

A new method, the Perpendicular Distance Estimation Method (PDEM), to estimate the precision of a Digital Elevation Model (DEM) with its effectiveness in the evaluation of vertical and horizontal error is presented in a previous work: when the error is accepted as random the PDEM may evaluate the vertical error, - without systematic error as it happens using the vertical distance method- and also may evaluate the horizontal one (horizontal isotropic error) under certain irregular terrain conditions, without using benchmarks.
In the case of the DEM obtained by IFSAR techniques, the error in the vertical axis is correlated with the error in the range-axis. A rotation has to be done to find not correlated directions.
The contribution of this paper is to assess the PDEM effectiveness to estimate the error in the three not correlated directions: the beam axis, the azimuth axis and the axis normal to the previous two (y’; the rotated range axis). Simulations are presented in detail, starting from a real reference DEM, with 100 000 points. The results confirm that the PDEM error estimation is good in the beam and in the y’ directions, and the more uneven the terrain, the better the estimate of the azimuth axis error.
First report on kdr mutations in wild populations of Aedes aegypti from Argentina determined by a novel multiplex high resolution melting PCR method

Published: March 2023

Abstract

Background:
Aedes aegypti is an urban mosquito vector of dengue and other arboviruses. During epidemic periods, pyrethroid insecticides are used for the control of adult mosquitoes; the worldwide distributed resistance to these insecticides is a cause of failures in vector control campaigns. The primary target of pyrethroids is the voltage-gated sodium channel; point mutations on this channel, called kdr mutations, are associated with pyrethroid resistance. Two kdr mutations, called V1016I and F1534C, augmented in frequency in natural populations of Ae. aegypti from the Americas in the last decade; their association with pyrethroid resistance has been largely demonstrated in field populations throughout the country, and in in vitro assays. The diagnostic of kdr polymorphisms allows an early detection of insecticide resistance spreading, which is critical for timely decisions on vector management. Given the relevance of resistance management, high-throughput methods for kdr genotyping are valuable tools for resistance monitoring programs. These methods should also be cost-effective, to allow regional-scale surveys. Despite the extended presence of Ae. aegypti and the incidence of dengue in Argentina, the presence, abundance and distribution of kdr mutations were not reported in this country up to date.
Methods:
Aedes aegypti samples were collected from Metropolitan Area of Buenos Aires, and northern localities of Tartagal (Salta province) and Calilegua (Jujuy province). A high resolution melting assay was developed for the simultaneous detection of V1016I and F1534C kdr mutations.
Results:
We demonstrate the presence of kdrmutations in Argentina in regions under different selection pressure with pyrethroids. We also report a multiplex high-throughput assay based in high resolution melting PCR for the simultaneous genotyping of V1016I and F1534C kdr mutations.
Conclusions:
We report for the first time the presence of kdr mutations in distant populations from Argentina, with different epidemiological situations and different history of mosquito control efforts. We have developed a high-throughput method for the genotyping of kdr mutations in Ae. aegypti from the American continent. Given its convenient cost and running time, this method can be incorporated in control campaigns for monitoring the presence and spreading of kdr alleles.
