Published: February 2023

AbstractPre-stack seismic inversion based on sensitive elastic parameters is critical in reservoir lithology prediction and geofluid identification. The ability of a single elastic attribute to identify a reservoir depends on its sufficient sensitivity to distinguish the target reservoir from the surrounding sediments. In general, high-dimensional data space composed of multiple elastic attributes is more conducive to describing reservoir characteristics. Therefore, a multiple elastic attribute fusion method using affinity propagation clustering strategy for gas hydrate reservoir identification is proposed. Rock-physics modeling is the most effective tool to determine the influence of microscopic physical parameters on macroscopic elastic response and to quantitatively evaluate the sensitivity of elastic attributes. Consequently, a rock-physics model of hydrate sediments considering the non-negligible shear properties of hydrates is constructed to clarify reservoir-sensitive elastic parameters. Additionally, a clustering evaluation indicator is defined to determine the optimal data clustering dimension in terms of feasibility and economy of the proposed method, and to avoid bias in the results due to data redundancy. It is shown that the 3D elastic attribute space consisting of shear modulus, Young's modulus, and S-wave velocity has the best discrimination ability for hydrate reservoirs. The logging data are used to verify the feasibility and effectiveness of the proposed method. Finally, the hydrate reservoir development is accurately discriminated by using the multiple elastic attributes yield from the pre-stack seismic inversion and combined with the fusion strategy.

AbstractIn this paper we propose an object detector based on deep learning for scanning samples of table olives. For the construction of the system we have used a Mask R-CNN neural network. This network is able to segment the image providing a mask for each of the olives in the sample from which we can obtain the calibre of the object. In addition, the system is able to measure the degree of ripeness of the olives classifying them as green, semi-ripe and ripe, and identifying those fruits that are defective due to disease or damage caused by the harvesting process. The proposed system achieves success rates of 99.8% in the detection of olive fruits in photograms, 93.5% in the classification of fruit by ripeness and close to 80% in the detection of defects.

Abstract
Silica nanoparticles have become an important tool in material sciences, nanomedicine, biotechnology, and pharmaceutics, with recent suggested applications also in environmental sciences. In life and environmental sciences, the application field is usually aqueous media; however, the crucial issue of silica nanoparticle dissolution behavior and rate in the target medium is often neglected, overlooked, or taken for granted. Silica nanoparticles are not stable in aqueous solutions until equilibrium silica concentrations are reached. While for life science applications, the degradability of silica nanoparticles is prerequisite for biocompatibility, this characteristic impedes the successful application of silica nanoparticles as environmental tracer, where long-term stability is needed. In this study, the impact of external (temperature, pH values, salinity, availability of silica) and internal (degree of condensation, size, porosity) parameters on the stability of ~ 45-nm-sized silica nanoparticles is characterized. Results show that external factors such as elevated temperature and alkaline pH-values accelerate the dissolution, acidic pH, high salinities, and high initial silica concentrations exhibit a contrary effect. Consequently, in applications, where external parameters cannot be controlled (e.g., in vivo, subsurface reservoirs), dissolution control and stability improvement of silica nanoparticles can be achieved by various means, such as adding a protective layer or by condensation of the silanol bonds through calcination.

Published: February 2023

AbstractParkinson’s disease (PD) is a chronic neurodegenerative disorder characterized by dopaminergic neuron loss, which is related to excessive reactive oxygen species (ROS) accumulation. Endogenous peroxiredoxin-2 (Prdx-2) has potent anti-oxidative and anti-apoptotic effects. Proteomics studies revealed plasma levels of Prdx-2 were significantly lower in PD patients than in healthy individuals. For further study of the activation of Prdx-2 and its role in vitro, SH-SY5Y cells and the neurotoxin 1-methyl-4-phenylpyridinium (MPP+) were used to model PD. ROS content, mitochondrial membrane potential, and cell viability were used to assess the effect of MPP+ in SH-SY5Y cells. JC-1 staining was used to determine mitochondrial membrane potential. ROS content was detected using a DCFH-DA kit. Cell viability was measured using the Cell Counting Kit-8 assay. Western blot detected the protein levels of tyrosine hydroxylase (TH), Prdx-2, silent information regulator of transcription 1 (SIRT1), Bax, and Bcl-2. The results showed that MPP+-induced accumulation of ROS, depolarization of mitochondrial membrane potential, and reduction of cell viability occurred in SH-SY5Y cells. In addition, the levels of TH, Prdx-2, and SIRT1 decreased, while the ratios of Bax and Bcl-2 increased. Then, Prdx-2 overexpression in SH-SY5Y cells showed significant protection against MPP+ -induced neuronal toxicity, as evidenced by the decrease in ROS content, increase in cell viability, increase in the level of TH, and decrease in the ratios of Bax and Bcl-2. Meanwhile, SIRT1 levels increase with the level of Prdx-2. This suggests that the protection of Prdx-2 may be related to SIRT1. In conclusion, this study indicated that overexpression of Prdx-2 reduces MPP+-induced toxicity in SH-SY5Y cells and may be mediated by SIRT1.

Published: February 2023

AbstractAimsThis study aims to identify some of the key soil-related factors that underpin the distribution of plant communities and provide a more comprehensive understanding of an old, climatically buffered infertile landscape including kwongkan habitats. We investigate the pedological, topographical and hydrological correlates of abundance and floristic community distribution within the Alison Baird Reserve, a floristically diverse, old and climatically weathered landscape in south-west Western Australia.MethodsFifty-four soil samples were collected across 0.165 km2and analysed for a range of physical and chemical properties. Samples were taken from the topsoil and subsurface, and a combination of statistical and geostatistical methods were used to examine soil–plant community distribution relationships.ResultsElevation, sub-surface moisture, electrical conductivity and clay content were the most important factors in determining vegetation composition and distribution; with sub-surface properties varying more between floristic communities and correlating more strongly than topsoil factors. Associations between soil nutrients (Phosphorus, Nitrogen, Carbon) and community distributions were not as significant as expected, likely due to the depleted nature of the soil system.ConclusionThe significance of soil parameters including particle size, moisture, elevation, water repellence and depth to water table suggests that water availability and retention within the soil is a key correlate of the distribution of floristic communities at the site and may act as a pathway to explain large scale variation in plant communities across the south-west of Western Australia. This understanding will help conservation and management of areas with such high biodiversity including relocation of endangered flora.
ECB unconventional monetary policy and SME access to finance
Authors: Finnegan Marie , Kapoor Supriya 
Published: February 2023

AbstractSmall- and medium-sized enterprises (SMEs) account for two-thirds of employment in the euro area which makes them a priority for the transmission of monetary policy to the real economy. SMEs in Europe experienced a credit crunch following the sovereign debt crisis. Over the period 2014–2019, the European Central Bank (ECB) engaged in unconventional monetary policy (UMP) to restore funding conditions in the euro area, to support stronger economic growth and higher inflation. We use the ECB/EC Survey on the Access to Finance of Enterprises to examine the relationship between monetary policy and SME access to finance in countries that were most affected by the crisis as follows: Greece, Ireland, Italy, Portugal and Spain. We show that the implementation of UMP increases the probability that firms with higher debt-to-assets ratio remain credit constrained in stressed countries, although this effect becomes insignificant in non-stressed countries. Our findings suggest that monetary policy is transmitted unevenly to leveraged SMEs across jurisdictions. Additionally, we find little evidence that risky firms are credit constrained during periods of UMP, when risk is measured from the firms’ own viewpoint. However, our heterogenous analysis shows that smaller and younger firms—which are also considered to be risky—remain credit constrained over this period. Policy should ensure that UMP trickles down to SMEs regardless of their size, age or location. Tweetable line: Leveraged SMEs in stressed countries are more likely to remain credit constrained even when monetary policy is expansionary. Policy must do more to support small and young firms’ access to credit to facilitate higher investment and growth.
Rent-Free in Your Head? How Generalised Trust is Affected by the Trust and Salience of Outgroups
Authors: Kumove Michael 
Published: February 2023

AbstractWhat is the relationship between people’s trust in specified outgroups (such as ‘French people’ or ‘immigrants’) and their generalised trust? This relationship has never been empirically tested, which is troubling for the large body of research on the link between ethnic diversity and trust which seemingly assumes that outgroup trust does affect generalised trust. In this paper, I use individual-level survey data to examine how outgroup trust affects generalised trust in the United States and Croatia. Although the two types of trust are correlated, I find no evidence that people account for outgroup salience when translating outgroup trust into generalised trust, as previous theories have suggested. This raises the possibility that a different type of mechanism may be responsible instead, or perhaps that the association is non-causal and trust is a fixed personality trait which is not alterable by experience. In either case, it seems that the conventional explanation for how ethnic diversity reduces generalised trust—namely that it reduces outgroup trust which then feeds through into lower generalised trust—may need to be revised. I conclude by discussing limitations and some suggestions for further research.
Coordination and obsolescence: a response on behalf of measurement realism
Authors: Wolff J. E. 
Published: February 2023

AbstractMeasurement realism, the view that measurement targets quantitative attributes and that not all attributes are quantitative, has come under attack both from metrologists and philosophers. In this paper, I take a close look at two influential arguments against measurement realism: the argument from obsolescence and the argument from coordination. I concede that these arguments do challenge the epistemological position traditionally taken by measurement realists, but argue that the metaphysical core of measurement realism survives the challenge posed by these arguments. This metaphysical core is vital to maintaining a clear and ambitious standard for successful measurement.
On the Use of Surface Roughness Parameters
Authors: Persson B. N. J. 
Published: February 2023

AbstractIn most practical applications, surface roughness is characterized by just one or two parameters (numbers). I show that the standard maximum surface height parameters fluctuate strongly between different surface realizations (or measurements), and should not be used in the design of engineering components. I show how some roughness parameters depend on the size of the roll-off region in the surface roughness power spectra, and introduce a new height parameter which is very reproducible. The numerical results presented agree well with experimental observations.

Published: February 2023

AbstractSix biofilm carriers with different polymer were studied in fixed-film systems under anoxic conditions. Different media of polymers influence wastewater treatment performance. The aim of this study was to investigate different polymeric materials, polyethylene terephthalate (PET), polyvinyl chloride (PVC), polypropylene (PP), high-density polyethylene (HDPE), and polymethyl methacrylate (acrylic), that affect bacterial attachment and biofilm formation in biofilm-based wastewater treatment technologies. Water contact angle (WCA) measurement was employed to analyze the role of wetting (hydrophilic/hydrophobic) of polymeric material surfaces in the initial phase of bacterial attachment. The increase of biofilm formation during the observation was determined by gravimetric (total attached solid) and microscopic (SEM and CLSM) analysis. The results showed the value for WCA of PET < HDPE < PVC < PP < acrylic, which indicated that a higher hydrophilicity surface leads to a higher total attached solid (TAS), biofilm formation rate, and biofilm thickness on the surface of media. The hydrophilic material (i.e., PET and HDPE) demonstrated wastewater treatment performance better than slightly hydrophilic material (i.e., PVC, PP, and acrylic) under a steady-state period (over an 80-day operation). The data showed a positive correlation between hydrophilic material and COD, NH4+-N, and TP removal. Hydrophilic material was beneficial for a fast start-up and stable biofilm formation of a fixed-bed biofilm reactor. PET media showed feasible polymer types compared to HDPE, PVC, and PP; thus, it can be used as an alternative biofilm carrier media in a larger-scale application. The findings of this study highlighted the polymeric material type has a significant effect on the performance of fixed-bed wastewater treatment.
Criminal records versus rehabilitation and expungement: a randomised controlled trial
Authors: Bland Matthew , Ariel Barak , Kumar Sumit 
Published: February 2023

Abstract
Purpose
What is the effect of having a criminal record compared to having the criminal record expunged in exchange for participating in a rehabilitative programme? The available evidence focuses on programmes comprised of the criminal record for the offence (i.e. labelling) and a punitive sanction or rehabilitative scheme. The interaction between the labelling and the sanction has made distinguishing the effect of each penological approach a challenge.

Methods
We use a pretest–posttest control group design with a cohort of 341 low-harm offenders randomly assigned to either a simple, unconditional, caution or a 16-week rehabilitation treatment programme (after which the criminal record was automatically expunged). New crimes and a measure of harm were used as outcome variables.

Results
Intention-to-treat analysis shows no significant difference in prevalence, crime count or crime harm. Factoring in those individuals who actually completed the programme changes this story. An instrumental variables analysis used to adjust for treatment compliance suggests that the offer to expunge the criminal record following participation in rehabilitation programmes reduces both crime count and crime harm.

Conclusions
We conclude that as evidence on the adverse effects of criminal records on recidivism mounts, out of court disposals that lead to an expungement of the label ‘offender’ may provide promising intervention for low-harm offences. The experiment also highlighted the importance of secondary analytic strategies in experiments alongside the standard intention-to-treat model.
New geochemical data for defining origin and distribution of mercury in groundwater of a coastal area in southern Tuscany (Italy)

Published: February 2023

Abstract
A geochemical study was conducted in a coastal plain in the Orbetello Lagoon area in southern Tuscany (Italy), acquiring new data on groundwater, lagoon water, and stream sediment for insights into the origin, distribution, and behaviour of mercury in a Hg-enriched carbonate aquifer. The main hydrochemical features of the groundwater are ruled by the mixing of Ca–SO4 and Ca–Cl continental fresh waters of the carbonate aquifer and Na–Cl saline waters of the Tyrrhenian Sea and Lagoon of Orbetello. Groundwater had highly variable Hg concentrations (< 0.1–11 μg/L) that were not correlated with the percentage of saline water, depth in the aquifer, or distance from the lagoon. This excluded the possibility that saline water could be the direct source of Hg in groundwater and responsible for release of the element through interaction with the carbonate lithologies of the aquifer. The origin of Hg in groundwater could be ascribed to the Quaternary continental sediments overlying the carbonate aquifer because i) high Hg concentrations were found in the continental sediments of the coastal plain and in the contiguous lagoon sediments; ii) waters from the upper part of aquifer had the highest Hg concentrations; iii) Hg levels in groundwater increased with increasing thickness of the continental deposits. The high Hg content in the continental and lagoon sediments is geogenic due to regional and local Hg anomalies and to sedimentary and pedogenetic processes. It can be assumed that i) water circulating in these sediments dissolves the solid Hg-bearing constituents and mobilises this element mainly as chloride complexes; ii) Hg-enriched water moves from the upper part of the carbonate aquifer due to the cone of depression generated by intense pumping of groundwater by fish farms in the study area.

Published: February 2023

Abstract
Purpose
Postoperative loss of control eating (LOCE) has detrimental associations with weight outcomes and mental health following bariatric surgery. However, little is known regarding LOCE course following surgery and preoperative factors that predict remittance, continuance, or development of LOCE. The present study aimed to characterize LOCE course in the year following surgery by identifying four groups: individuals with (1) postoperative de novo LOCE, (2) maintained LOCE (endorsed at pre- and post-surgery), (3) remitted LOCE (endorsed only at pre-surgery), and (4) those who never endorsed LOCE. Exploratory analyses examined group differences in baseline demographic and psychosocial factors.

Materials and Methods
A total of 61 adult bariatric surgery patients completed questionnaires and ecological momentary assessment at pre-surgery and 3-, 6-, and 12-month postoperative follow-ups.

Results
Results showed that 13 (21.3%) never endorsed LOCE prior to or after surgery, 12 (19.7%) developed LOCE after surgery, 7 (11.5%) evidenced remittance from LOCE after surgery, and 29 (47.5%) maintained LOCE prior to and after surgery. Relative to those who never endorsed LOCE, all groups who evidenced LOCE before and/or after surgery reported greater disinhibition; those who developed LOCE reported less planned eating; and those with maintained LOCE reported less satiety sensitivity and greater hedonic hunger.

Conclusion
These findings highlight the importance of postoperative LOCE and need for longer-term follow-up studies. Results also suggest a need to examine the longer-term impact of satiety sensitivity and hedonic eating on LOCE maintenance, and the extent to which meal planning may buffer risk for de novo LOCE following surgery.

Published: February 2023

AbstractMaturity is an important factor in regulating seed vigor, while inappropriate harvest date affects seed vigor seriously. Here we reported that the seed vigor was the highest among 25–28 days after pollination, and these days were the best harvest time for sunflower seeds. Seed moisture content increased first and then decreased, while seed dry weight increased continuously with the advancement of seed development. Oil and protein are the main nutriments in mature sunflower seeds and changes in both contents were consistent with the seed dry weight. For antioxidases, the activity of ascorbate peroxidase (APX) was decreased gradually before seed maturity. Compared to gibberellin (GA), whose content decreased, abscisic acid (ABA) accumulated first and then decreased during the seed development. Moreover, the content of spermidine (Spd) increased continually, although no regularity of variation was found in putrescine (Put) and spermine (Spm). Further analysis showed that the activities of GA3ox and GA20ox, NCED and ABA8ox, SAMDC and SPDS and corresponding genes expression resulted in changes of GA, ABA and Spd accumulation, respectively. In addition, seed moisture, soluble sugar, GA, ABA content and APX activity were significantly negatively correlated with seed vigor indexes, while seed dry weight, oil, protein and Spd content were significantly positively correlated with seed vigor indexes. These metabolic processes may be closely related to seed vigor formation, and can be used to predict seed vigor.
