Published: April 2023

Abstract
Radon and its daughters are one of the most important
background sources for low-background liquid scintillator (LS)
detectors. The study of the diffusion behavior of radon in the LS
contributes to the analysis of the related background caused by
radon. Methodologies and devices for measuring radon's diffusion
coefficient and solubility in materials are developed and
described. The radon diffusion coefficient in the LS was measured
for the first time and the solubility coefficient was also
obtained. In addition, the radon diffusion coefficient in the
polyolefine film which is consistent with data in the literature was
measured to verify the reliability of the diffusion device.

Abstract
Gold wire is commonly used for quality assurance (QA) of the neutron beam in a boron neutron capture therapy (BNCT) system. It is set in water and irradiated with the neutron beam, and then 412-keV gamma photons from the activated gold wire are measured by a semiconductor detector. Since this procedure takes time and labor, a more efficient method is desired. To reduce the time and labor to measure the radioactivity of an activated gold wire, we carried out imaging of 412-keV gamma photons from the activated gold wire using a developed high-energy gamma camera. After the gold wire was set in the depth direction in a water-filled phantom and irradiated with neutron beams using the BNCT system, gamma photon imaging was conducted with the developed high-energy gamma camera. On the measured image, a depth profile was set to obtain the neutron distribution, and this was compared with the profile sequentially measured with a semiconductor detector. An image of the 412-keV gamma photons was obtained with an imaging time of 1.5 hours. The estimated depth profile of the neutron beam from the gamma camera image closely matched that measured with a semiconductor detector. Imaging of the gamma photons emitted from the activated gold wire was possible, and it offers an efficient method to measure the thermal neutron distribution of the BNCT system. This method has the potential to reduce the time and labor for QA of a BNCT system.
Changing cropland in changing climates: quantifying two decades of global cropland changes

Published: April 2023

Abstract
Climate change is impacting global crop productivity, and agricultural land suitability is predicted to significantly shift in the future. Responses to changing conditions and increasing yield variability can range from altered management strategies to outright land use conversions that may have significant environmental and socioeconomic ramifications. However, the extent to which agricultural land use changes in response to variations in climate is unclear at larger scales. Improved understanding of these dynamics is important since land use changes will have consequences not only for food security but also for ecosystem health, biodiversity, carbon storage, and regional and global climate. In this study, we combine land use products derived from the Moderate Resolution Imaging Spectroradiometer with climate reanalysis data from the European Centre for Medium-Range Weather Forecasts Reanalysis v5 to analyze correspondence between changes in cropland and changes in temperature and water availability from 2001 to 2018. While climate trends explained little of the variability in land cover changes, increasing temperature, extreme heat days, potential evaporation, and drought severity were associated with higher levels of cropland loss. These patterns were strongest in regions with more cropland change, and generally reflected underlying climate suitability—they were amplified in hotter and drier regions, and reversed direction in cooler and wetter regions. At national scales, climate response patterns varied significantly, reflecting the importance of socioeconomic, political, and geographic factors, as well as differences in adaptation strategies. This global-scale analysis does not attempt to explain local mechanisms of change but identifies climate-cropland patterns that exist in aggregate and may be hard to perceive at local scales. It is intended to supplement regional studies, providing further context for locally-observed phenomena and highlighting patterns that require further analysis.
Prediction of Rubber Yield Based on Soil Water Content
Authors: Cahyo A N , Ardika R 
Published: April 2023

Abstract
Fluctuation of monthly rainfall resulted in fluctuation of monthly rubber yield. This study was aimed to determine a model to predict rubber yield based on soil water content. This study was conducted at Indonesian Rubber Research Institute, South Sumatera in May 2022. The plant materials used in this study were rubber clones PB 260 that were planted in 2001 in two blocks of rubber field. The soil texture in these two blocks was clay loam with good drainage conditions. The average of monthly soil water content and rubber yield data for 11 years from the first block was used to determine the model. Whereas the average of monthly soil water content and rubber yield data for 12 years from the second block was used to validate the model. The soil water content was generated by field water balance calculation. The regression and correlation analysis showed that the highest correlation and the most suitable model to predict rubber yield based on soil water content was the power model with formula Y = 0.0668X2.1423 (coefficient of determination (R2) = 0.80). Where, Y = rubber yield (kg/month) and X = soil water content (%). Furthermore, the validation of the model showed that the goodness of match (GOM), Pearson correlation coefficient (R), coefficient of determination (R2), and root mean square error (RMSE) were 0.94, 0.95, 0.90. and 10.3 respectively. These values showed that the model was accurate and strong enough to predict rubber yield based on soil water content.

Published: April 2023

Abstract
Endophytic bacteria inhabit internal plant tissue and generally promote plant growth, showing no external sign of infection or negative effect on their host plant. Endophytes play diverse roles including nutrient acquisition, production of phytohormones and siderophores, protection against abiotic stresses. The purpose of this study was to isolate and characterize endophytic bacteria which have the specific capability of the acquisition of nutrients especially Phosphate Solubilizing Bacteria (PSB) and potentially Nitrogen Fixing Bacteria (NFB) from the leaf and root of rice planted on the conventional wetland of Inceptisol. Isolation of endophytic bacteria was conducted by sterilizing the surface of plant samples and then inoculating using the spread plate method on pikovskaya and yeast extract mannitol agar media. The growing bacterial colonies on the media showed that the diversity and population density of endophytic PSB in the root was higher than in the leaf tissue, namely 4 types of isolates with 1,526x105 CFU/g in the root and 2 types of isolates with 0.0395x105 CFU/g in the leaf. On the other hand, the diversity of endophytic potentially NFB in the leaf was higher than in the root tissue namely 5 and 3 types of isolates, but the population density was higher in the root at the level 11,55x105 CFU/g than in the leaf at 5,976x105 CFU/g. The next research is necessary to compare endophytic bacteria from rice planted in inorganic and organic cultivation systems, and continued with the examination of the effect of inoculation of those endophytic bacteria to the targeted crops.

Abstract
Pacitan Regency is one of the potential areas for the development of cocoa (Theobroma cacao L). Plants need certain conditions to produce optimally. Land suitability is a way to find out whether land conditions in Kebonagung District are suitable or not for cocoa plants. This study evaluates land suitability for cocoa plants in Kebonagung District, Pacitan Regency. The research was conducted using descriptive method through a survey approach. Based on the overlay of soil type maps, topographic maps, rainfall maps, and administrative maps, ten land map units (LMU) were obtained. Morphological analysis and soil characteristics were carried out qualitatively in the field and quantitatively in the laboratory. Determination of land suitability is done by matching the characteristics of the land with the conditions for growing cocoa plants. The results showed that at LMU 2, 3, 4, 5, 6, 8, 9, and 10 were moderately suitable for the class of land suitability, while LMU 1 and 7 were marginally suitable. The limiting factors are the length of the dry month, humidity, pH, available potassium, base saturation (BS), erosion hazard and slope. After improving the limiting factor, the potential land suitability class was obtained in the S2 class (moderately suitable) for all LMUs.

Abstract
Refractive disorder is the most prevalent cause of visual impairment worldwide. While treatment of refractive errors can bring improvement to quality of life and socio-economic benefits, there is a need for individualization, precision, convenience, and safety with the chosen method. Herein, we propose using pre-designed refractive lenticules based on poly-NAGA-GelMA (PNG) bio-inks photo-initiated by digital light processing (DLP)-bioprinting for correcting refractive errors. DLP-bioprinting allows PNG lenticules to have individualized physical dimensions with precision achievable to 10 µm (μm). Material characteristics of PNG lenticules in tests included optical and biomechanical stability, biomimetical swelling and hydrophilic capability, nutritional and visual functionality, supporting its suitability as stromal implants. Cytocompatibility distinguished by morphology and function of corneal epithelial, stromal, and endothelial cells on PNG lenticules suggested firm adhesion, over 90% viability, phenotypic maintenance instead of excessive keratocyte-myofibroblast transformation. In-vitro immune response analyzed by illumina RNA sequencing in human peripheral blood mononuclear cells indicated that PNG lenticules activated type-2 immunity, facilitating tissue regeneration and suppressing inflammation. In-vivo performance assessed using intrastromal keratoplasty models in New Zealand white rabbits illustrated that implantation of PNG lenticules maintained stable optical pathway, induced controlled stromal bio-integration and regeneration, avoided complications such as stromal melt, interface scarring, etc, but exerted no adverse effects on the host. Postoperative follow-up examination on intraocular pressure, corneal sensitivity, and tear production remained unaffected by surgery up to 1-month post-implantation of PNG lenticules. DLP-bioprinted PNG lenticule is a bio-safe and functionally effective stromal implants with customizable physical dimensions, providing potential therapeutic strategies in correction of refractive errors.
Effect of addition of alumina and rare-earth oxide particles on the corrosion resistance and mechanism of low carbon low alloy steel
Authors: Gao Yu-long , Xiao Zhi-xia , Liu Bao-xi , Kong Ling-hao , Feng Jian-hang , Huifen Peng 
Published: April 2023

Abstract
The corrosion mechanism of the low carbon low alloy steel with Al2O3 particles and rare Earth (RE) oxide particles was compared in a simulated marine environment. It is shown that when the Al2O3-containing particles are introduced, the number density of nonmetallic particles of the steel increases twice, and the average particle size decreases from approximately 2.4 μm to 1.4 μm. With the introduction of Al2O3-containing particles, the amount of pitting corrosion increases. Furthermore, pitting corrosion occurs more uniformly owing to the fineness of the Al2O3 particles, thereby leading to smaller, shallower pits after the Al2O3 particles are shed. Hence, the corrosion performance of the steel with Al2O3 particles is significantly improved than that of the steel without Al2O3 particles. By adding RE oxide particles into steel, the nonmetallic particles in steel are refined but not as effectively as that achieved by adding the Al2O3-containing particles. Different from Al2O3 particles, Cu is obviously enriched in the location of RE oxide particles at the initial corrosion stage, which makes the steel exhibit the best corrosion resistance. Cu enrichment is attributed to the mobile Cu present in the rust layer and to the micro acid region formed around the RE oxide particles.

Treatment of hidradenitis suppurativa with brodalumab in biologic treatment failures: experiences from a specialty clinic
Authors: Kearney Niamh , Hughes Rosalind , Kirby Brian 
Published: April 2023

Abstract
Hidradenitis suppurativa (HS) is characterized by increased interleukin (IL)-17A/C/F. Two open-label trials of brodalumab, an IL-17 receptor antagonist, have been completed, with 8 of 10 patients receiving brodalumab fortnightly and 10 of 10 patients receiving brodalumab weekly achieving 75% Hidradenitis Suppurativa Clinical Response. All patients were biologic ‘experienced’ but were not reported to have failed biologic treatment. We report outcomes for eight patients with HS who had failed at least one biologic, treated with brodalumab 210 mg fortnightly, to provide real-world evidence. Four of eight patients remain on brodalumab, with a mean treatment duration of 11.3 months. All patients who remain on brodalumab subjectively report continued treatment efficacy. The mean Dermatology Life Quality Index reduced from 20.6 to 16.8 at week 16. All patients required concurrent antibiotics due to flares. Brodalumab may be effective in patients who have previously failed multiple biologics, but efficacy in our real-world study falls short of the two open-label trials. This may reflect severe treatment-resistant disease. In the absence of further licensed treatments for HS, brodalumab may be a good option following adalimumab failure.
Predator and Alien: the threat of predatory journals and conferences
Authors: Leducq Sophie , Bonsu Natalie , Clement Kate , Barlow Richard , Williams Hywel C 
Published: April 2023

Abstract
Predatory journals, first recognized in the early 2000s, are fraudulent publications characterized by aggressive marketing solicitations and deviation from best publishing practices. These journals claim to be legitimate scholarly publications, and accept articles with no or poor peer review processes or quality checks, with rapid publication on payment by authors. They are a global threat as they are dishonest, lack transparency and seek only financial gain. More recently, predatory conferences have emerged and are expanding rapidly. Although they appear to be legitimate scientific conferences, they are also characterized by an overriding profit motive, with no concern for academic values. Predatory journals and conferences are on the rise; dermatology trainees, readers and those new to publishing and conferences are vulnerable to predatory exploitation. The consequences of falling victim to such predation include damage to the external reputation of the authors and their institution, and heightened concerns about the legitimacy of the research. This educational review defines predatory journals and conferences, and summarizes their distinguishing features such as a poor or no peer review process, rapid acceptance, flattering language and lack of meeting. It highlights the consequences of publishing in a predatory journal or attending a predatory conference, and outlines several tools available that dermatology researchers can use to recognize and reduce the likelihood of falling prey to a predatory journal or conference.
Balanced Off-Chain Payment Channel Network Routing Strategy Based On Weight Calculation
Authors: Liu Ya , Wu Yuanhang , Zhao Fengyv , Ren Yanli 
Published: April 2023

Abstract
Off-chain payment channel network is an effective solution to deal with low throughput and high load on the blockchain. However, the quality of the routing scheme will directly affect the performance of the off-chain network system. Existing routing schemes cannot select an appropriate transaction path according to the actual needs of user nodes. And they may also lead to network congestion, channel imbalance and node centralization. This paper proposes a new balanced routing selection scheme based on weight calculation called BRBW, which builds a weight model by Analytic Hierarchy Process. BRBW comprehensively considers the channel capacity, handling fee and path length to improve transaction success rate, reduce channel congestion and maintain the long-term sustainability of the payment channel. It uses a modified maximum flow algorithm to find paths with sufficient capacity and selects the transaction path for a large payment through linear programming. Finally, we do some experiments and compare with state-of-the-art approaches in the test environment. Simulation results show that under the same network environment, the payment success rate of the BRBW is above 75%, and the channel utilization rate is about 10% higher than other schemes.
Formal Employment and Organised Crime: Regression Discontinuity Evidence from Colombia
Authors: Khanna Gaurav , Medina Carlos , Nyshadham Anant , Tamayo Jorge , Torres Nicolas 
Published: April 2023

Abstract
Safety net programs, common in settings with high informality like Latin America, often use a means test to establish eligibility. We ask: in settings in which organised crime provides lucrative opportunities in the informal market, will discouraging formal employment via benefits eligibility criteria increase criminal enterprise activity? We link administrative socioeconomic microdata with the universe of arrests in Medellín over a decade, and exploit exogenous variation in formal-sector employment around a socioeconomic-score cutoff, below which individuals receive generous benefits if not formally employed. Regression discontinuity estimates confirm this policy reduced formal-sector employment and generated a corresponding increase in arrests associated with organised crime. We do not find increases for crimes unlikely to be associated with organised entities, such as crimes of impulse or opportunity. Effects on arrests are strongest in neighbourhoods where organised crime is most prevalent.

Abstract

OBJECTIVES
A better surgical approach for acute DeBakey type I dissection has been sought for decades. We compare operative trends, complications, reinterventions and survival after limited versus extended-classic versus modified frozen elephant trunk (mFET) repair for this condition.

METHODS
From 1 January 1978 to 1 January 2018, 879 patients underwent surgery for acute DeBakey type I dissection at Cleveland Clinic. Repairs were limited to the ascending aorta/hemiarch (701.79%) or extended through the arch [extended classic (88.10%) or mFET (90.10%)]. Weighted propensity score matched established comparable groups.

RESULTS
Among weighted propensity-matched patients, mFET repair had similar circulatory arrest times and postoperative complications to limited repair, except for postoperative renal failure, which was twice as high in the limited group [25% (n = 19) vs 12% (n = 9), P = 0.006]. Lower in-hospital mortality was observed following limited compared to extended-classic repair [9.1% (n = 7) vs 19% (n = 16), P = 0.03], but not after mFET repair [12% (n = 9) vs 9.5% (n = 8), P = 0.6]. Extended-classic repair had higher risk of early death than limited repair (P = 0.0005) with no difference between limited and mFET repair groups (P = 0.9); 7-year survival following mFET repair was 89% compared to 65% after limited repair. Most reinterventions following limited or extended-classic repair underwent open reintervention. All reinterventions following mFET repair were completed endovascularly.

CONCLUSIONS
Without increasing in-hospital mortality or complications, less renal failure and a trend towards improved intermediate survival, mFET may be superior to limited or extended-classic repair for acute DeBakey type I dissections. mFET repair facilitates endovascular reintervention, potentially reducing future invasive reoperations and warranting continued study.
