Published: May 2023

Abstract
The U.S. Dept. of the Interior, Bureau of Mines, has designed and tested an isokinetic sampling probe for use in studying the hydrodynamic, thermodynamic, chemical, and physical properties of geobrines. This work was conducted as a part of the Bureau's mission to ensure an adequate supply of minerals to meet national economic and strategic needs. The probe consists of a sampling tube for obtaining the fluid sample and two probe consists of a sampling tube for obtaining the fluid sample and two pressure sensing tubes for use in controlling hydrodynamic conditions at pressure sensing tubes for use in controlling hydrodynamic conditions at the entrance to the sampling tube. The three tubes form the basic probe unit and can be mounted on brine processing equipment and pipelines as either a fixed- or an adjustable-position probe.
The isokinetic technique, involving sampling at a rate governed by the pressures in the two sensing tubes, is useful specifically for sampling pressures in the two sensing tubes, is useful specifically for sampling two-phase fluids. Samples so obtained are reproducible and representative of the fluid being sampled. The probe proved capable of examining two-phase flows of widely ranging fluid properties at the Bureau of Mines.

Published: June 2023

Abstract
Regular image analysis derived from confocal microscopic data of biological tissue samples with the Imaris software package involves a significant amount of repetition on the part of the researchers for each image. We developed a supervised automation protocol in our lab to execute our everyday cell and spot counting tasks (e.g., neuron, nucleus, macrophages) on images obtained from mouse cochlear samples. The proposed semi-automated protocol can be reproduced and customized by scientists working on basic and experimental neuro-immunology and neuroanatomy research and on other disciplines as well. Though it has some limitations and challenges, the protocol can be further enhanced with the integration of machine learning. We believe our developed protocol may enlighten the scientific community on the controlled automation of image analysis tasks, may translate to a substantial reduction of the manual labor of the researchers, and can increase laboratory efficiency and productivity.
2PSLAF: Privacy-Preserving Secure lightweight authentication framework for Vehicle-to-Vehicle communications
Authors: Rao P Muralidhara 
Published: May 2023

Abstract
Internet of Vehicular Things (IoVT) intended to connect vehicles in urban and rural areas to provide communication among the vehicles. With the rapid development of eHealth, the autonomous and intelligent vehicles play a vital role. Now a days, millions of vehicles equipped with smart sensors, devices, and communication facilities for providing quality of service at emergency. Due to network openness, unfortunately, IoVT is subject to a large number of potential issues related to security and privacy. This paper proposes an efficient privacy-preserving secure vehicle-to-vehicle (V2V) communication. Firstly, we propose a privacy-protected identity-based mutual authentication. Further, to enhance the security levels, the session key is derived from timestamps, a common key shared by the vehicles, privacy-protected identity and random nonce decided by both the vehicles. The security analysis shows our scheme withstands several potential attacks, including unknown key share attacks, replay attacks, and key-compromised impersonation attacks. The empirical results show the efficiency of the proposed scheme is computationally taking less time.

Abstract
In this study, two issues related to the pervious concrete are addressed, and a proper solution is drawn. The first issue is related to strength and the second one is related to permeability. We have used some of the available industrial waste like fly ash, silica fume, and furnace slag in replacement of cement at 20%, 35%, and 50%. The study is conducted to check whether this waste materials replacement can increase the strength and permeability of pervious concrete. Results revealed that fly ash replacement at 35% gave the best result than no cement replacement in both strength and permeability
Neural Network Interatomic Potential for Laser-Excited Materials
Authors: Plettenberg Pascal , Bauerhenne Bernd , Garcia M. 
Published: May 2023

Abstract
The design of new materials and the prediction of their properties by means of computational techniques has reached an unprecedent level of accuracy thanks to the development and use of machine-learning (ML) approaches. For instance, interatomic potentials based on ML algorithms have been increasingly used to perform large-scale, first-principles quality simulations of materials in the electronic ground state. However, they are unable to describe situations in which the electrons are excited, like in the case of material processing by means of femtosecond laser irradiation or ion bombardment. In this work, we propose a neural network interatomic potential, which involves a dependency on the electronic temperature and can therefore be applied to large-scale simulations of laser-excited materials. We explicitly construct the interatomic potential for silicon and demonstrate its capability of reproducing important physical properties with first-principles accuracy. Moreover, we use it to simulate laser-induced surface modifications on a silicon thin film and thereby consider time and length scales that are not feasible with first-principles approaches like density functional theory. The method is general and can be applied not only to other laser-excited materials but also to condensed and liquid matter under non-equilibrium situations in which electrons and ions exhibit different temperatures.
A resilient workforce: patient safety and the workforce response to a cyber-attack on the ICT systems of the national health service in Ireland

Published: May 2023

Abstract
Background In May 2021, the Irish public health service was the target of a cyber-attack. The response by the health service resulted in the widespread removal of access to ICT systems. While services including radiology, diagnostics, maternity, and oncology were prioritised for reinstatement, recovery efforts continued for over four months. This study describes the response of health service staff to the loss of ICT systems, and the risk mitigation measures introduced to safely continue health services. The resilience displayed by front line staff whose rapid and innovative response ensured continuity of safe patient care is explored.Methods To gain an in-depth understanding of staff experiences of the cyber-attack, eight focus groups (n = 36) were conducted. Participants from a diverse range of health services were recruited, including staff from radiology, pathology/labs, radiotherapy, maternity, primary care dental services, health and wellbeing, COVID testing, older person’s care, and disability services. Thematic Analysis was applied to the data to identify key themes.Results The impact of the cyber-attack varied across services depending on the type of care being offered, the reliance on software, and local IT support. Staff stepped up to the challenges and quickly developed and implemented innovative solutions, exhibiting great resilience, teamwork, and adaptability with a sharp focus on ensuring patient safety. The cyber-attack resulted in a flattening of the healthcare hierarchy, with shared decision-making at local levels leading to an empowered frontline workforce. However, participants in this study felt the stress placed on staff by the attack was more severe than the cumulative effect of the COVID-19 pandemic.Conclusions Limited contingencies within the health system IT infrastructure - what we call a lack of system resilience - was compensated for by a resilient workforce. Within the context of the prevailing COVID-19 pandemic, this was an enormous burden on a dedicated workforce. The adverse impact of this attack may have long-term and far-reaching consequences for staff wellbeing. Design and investment in a resilient health system must be prioritised.
Competing for space? - A multi-criteria scenario framework to model the energy-biodiversity-land nexus for regional renewable energy planning on a German case
Authors: Weber Jessica , Steinkamp Tim , Reichenbach Marc 
Published: May 2023

Abstract
Background: The need to balance renewable energy supply with biodiversity conservation has become increasingly urgent in light of current climate, energy, and biodiversity crises. However, the development of wind and solar energy often presents trade-offs such as competing for land use and potentially impacting species and habitats. To address these concerns, ‘priority zones’ for bird and bat species have been proposed as spatial designations for early species protection in the regional planning process. However, there are concerns that the areas suitable for wind and solar energy may be limited further, making it difficult to meet state- and regional-specific spatial targets for renewable energy sites.
Method: To help decision-makers deal with this challenge, a Multi-Criteria Scenario Framework has been developed and analyzed. It involves a habitat model of priority zones for species conservation and techniques from the intuitive logics scenario planning method. Through a regional case study, various planning criteria were analyzed scenario-driven, such as priority zones for species protection, settlement buffers, and forests. The framework indicates how criteria could be balanced to achieve wind energy spatial targets as well as targets for ground-mounted solar energy with the least possible impact.
Results: Results show that compared to other planning criteria, species priority zones had limited competition with spatial wind energy targets. Achieving these targets may require minimal adjustments, such as allowing wind energy in 1-3% of completely protected recreational landscapes. To reconcile land use demands in the energy transition, a balance between ‘green’ protected areas is necessary. Additionally, ground-mounted solar energy could replace some of the wind energy spatial targets while also meeting the overall solar development goals.
Conclusions: The framework provides transparency in assessing trade-offs between multiple objectives and helps quantify the ‘costs’ and ‘benefits’ in renewable energy planning. Adapting more flexible planning methods could help resolve the conflict between wind energy and species protection. Joint analysis of the areas needed for wind and solar energy and determining the optimal energy mix are gaining in importance. However, how the benefits of multi-criteria scenarios can be achieved within the confines of preoccupied and siloed organizations remains an ongoing research topic.
Invasive alien plants, conservation and livelihoods: the case of Vernonathura polyanthes in the Chimanimani Uplands of Zimbabwe
Authors: KACHENA Lameck , Shackleton Ross Taylor 
Published: May 2023

Abstract
Biological invasions can have major social-ecological consequences for local communities across the world. However, the dimensions (characteristics, infestation and socio-ecological impacts) of emerging invasive alien plants are often less well known but urgent information is needed to guide policy and management. In light of this, this paper assesses the social-ecological impacts of Vernonathura Polyanthes an emerging invasive alien plant, in a Zimbabwean upland landscape which supports conservation and livelihoods. Informed by exploratory participatory qualitative methodologies we discussed the socio-ecological and economic implications (benefits and impacts) of Vernonathura Polyanthes and how it is managed in the eastern parts of Chimanimani, Zimbabwe. We found that there are nuanced perspectives of this invasive tree among different socio-economic groups in the region who have different experiences of living with Vernonathura polyanthes. Some are embracing it for apiculture, firewood, and ethnomedicine, on the other hand for others the tree is negatively affecting key livelihoods (crop farming, pastoralism and tourism) that are common in the region. Local people also identified that Vernonathura Polyanthes is associated with ecological impacts that include loss of biodiversity, promoting pests and negatively affecting watersheds and associated water security. Mixed experiences on the plant are leading to different management practices, in turn inducing some conflicts among various actors. Based on our findings we suggest more should be done to better manage this invasive plant in the region before negative impacts become too great, particularly in the protected areas in the region.

Published: May 2023

Abstract
Background
Skeletal dysplasias (SD) are a diverse group of rare disorders in the chondro-osseous tissue that can have a significant impact on patient's functionality. The worldwide prevalence of SD at birth is approximately 1:5000 births. To date, disease burden and trends of SD in the Sri Lankan population have not been described in any epidemiological study. Our aim was to evaluate the burden and the current trends in hospital admissions for SD in the Sri Lankan population. A retrospective evaluation of hospital admissions for SD during 2017-2020 was performed using population-based data from the eIMMR database which covers government hospitals in the entire country. The trends in hospital admissions for SD by calendar year, age, and types of SD were described using appropriate summary statistics.
Results
Respective crude admission rates of SD in the years 2017, 2018, 2019 and 2020 were 5.2, 8.1, 8.0, and 6.5 per million population. A female predominance was noted during the studied period (1.4: 1). Of all reported cases majority (n=268; 44.2%) were children less than 4 years. Each year, 0-4 years age group represented 40% to 47% of the total hospital admissions. More than half of the cases were reported from Colombo (28.1%) and Kandy (25.4%) districts combined. Sixty percent of cases were diagnosed as osteogenesis imperfecta (OI). Rising trends were observed in the hospital admissions for osteogenesis imperfecta, achondroplasia and osteopetrosis, while other SD types collectively showed a relatively stable trend.
Conclusion
This preliminary study revealed a female predominance of SD and a relatively high admission rate of osteogenesis imperfecta in the Sri Lankan population. A distinct trend was not visible in the studied years probably due to the impact on hospital services due to COVID- Pandemic. Future research on the healthcare burden on families affected by SD is required to better understand the overall cost of care and identify therapies that reduce admission rates. This study highlights the value of analysing population-based data on rare diseases to improve healthcare in low-resource countries.

The liver tissue was evaluated histopathological, DNA damage, and proliferation status. In vitro study was consisted control and treatment groups (1500 and 2000 µg/ml of extracts). Cell viability and apoptosis were evaluated. As a result, decrease in the adhesion of EAT cells, and decreased DNA damage was observed extract group of in vivo study. The extracts both below and above 50 kDa were increased the apoptosis on cancer cells in in vitro study. The extract above 50 kDa were more active than those below 50 kDa. Lycium barbarum consumption may be effective in preventing cancer formation and slowing the progression of cancer.
Smooth transition regression model relating inflation to economic growth in Tunisia
Authors: BECHA Hamdi , KALAI Maha , HELALI Kamel 
Published: May 2023

Abstract

This paper examines the nature of the relationship between financial development and economic growth between 1965 and 2019, using the non-linear logistic smooth transition regression model and considering inflation as a threshold financial development. The results show the existence of a non-linear abrupt relationship with an inflation threshold equal to 3.63%. Specifically, when inflation is below 3.63 percent, all variables, including inflation, have a significant and positive impact on economic growth. However, when inflation exceeds the estimated threshold, inflation has a significant and negative impact with an elasticity equal to -0.365. Therefore, it is necessary to apply such measures to reduce the inflation pressures and promote economic growth through development finance by the banking sector.

Mechanism of stability enhancement of vane diffuser with different combined treatment methods
Authors: Li Wenjiao , Du Liming , Guan Tianmin , Bian Chenjie 
Published: May 2023

Abstract
To solve the problem of a narrow flow range of a vane diffuser at high speed while maintaining adequate centrifugal compressor performance, the wing diffuser of a turbocharged compressor is taken as the object; numerical simulation method is adopted, the effects of low-solidity treatment, combined treatment of low solidity and slotting, combined treatment of low solidity and casing on compressor stability and aerodynamic performance are studied respectively. The results of low-solidity treatment show that a low-solidity diffuser can broaden the flow range, even 1.8 times that of the vaneless diffuser, and the performance decrease is smaller than the vaneless diffuser (maximum reduction of pressure ratio is 6.4% less, the maximum reduction of efficiency is 4.1% less), but the stall boundary is shifted to the right. Then, the low-solidity diffuser is slotted in different axial and radial locations. They are slotting treatment of vane root, slotting treatment of vane tip, and casing treatment of circumferential slot at wheel cover. The results show that the location of the slot is the critical parameter; it can be determined by the location of the shockwave core area. Slotting treatment of the vane root, casing treatment of the circumferential slot, and slotting treatment of the vane tip can enhance stability from strong to weak and performance loss from large to small. Among them, slotting treatment at the front half chord root of the low-solidity diffuser vane can maximise the stable working flow range while the problem of stall boundary shifts to the right can be solved. The stall margin is widened to 1.8 times, the flow range is enlarged to 1.7 times, and the flow range is even 2.3 times that of the vaneless diffuser. Although it also causes the greatest loss of aerodynamic performance, the performance is still better than the vaneless diffuser.

Abstract
Panax ginseng products can be adulterated with materials from other Panax species. The purpose of this study is to provide a rapid P. ginseng authentication method for simultaneous identification of P. ginseng and detection of adulteration in ginseng products at different processing stages. First, a tetra-primer ARMS–PCR assay was designed based on a single-nucleotide polymorphism (SNP) within the trnL-trnF region and was tested at 28 PCR cycles with DNA extracted from Botanical Reference Materials (BRMs). Next, 5´ end random nucleotide and 3´ terminus phosphonothioates linkage modifications were incorporated into the inner primers to improve sensitivity and specificity at 40 PCR cycles. Finally, the modified assay was validated using characterized market ginseng materials and the detection limit was determined. The modified tetra-primer ARMS–PCR assay can achieve the desired sensitivity and specificity using one set of reaction conditions in ginseng materials at different stages. In validation, it was able to correctly identify target species P. ginseng and differentiate it from closely related species. This study suggests that the modified tetra-primer ARMS–PCR assay can be used for the rapid, species identity authentication of P. ginseng material in ginseng products. This assay can be used to complement chemical analytical methods in quality control, so both species identity and processing attributes of ginseng products can be efficiently addressed.
