Pore-Scale Evaluation of Physicochemical Interactions by Engineered Water Injections
Authors: Shapoval Artur , Zhuravljov Aleksandr , Lanetc Zakhar , Rahman Sheikh S. 
Published: May 2023

AbstractEngineered water injections have gained a lot of interest as an economic and effective method of improving the oil recovery. However, the complexity of the physicochemical interactions between the brines of various compositions, oil and rock has led researchers to provide multiple ways to explain this phenomenon. In this work, we evaluate the previously suggested mechanisms, namely wettability alteration and emulsification, against high-resolution micro-CT coreflood observations in a limestone sample. This is achieved by integrating the effects of above-mentioned mechanisms into a volume-of-fluid simulation by using geochemical modelling and experimental measurements. This has allowed us to explain the effect of capillary force affecting mechanisms, whereby we were able to achieve 6% increase in recovery factor. We have also observed that these mechanisms have limitation in improving recovery due to fingering and subsequent formation of the stagnation zones inside the core samples. When viscous effect is considered in numerical study, 22% increase in recovery is achieved by reorientation of the main flow paths and mobilisation of the previously unconnected oil clusters. This result is closer to 24% increase in recovery factor which was observed in experimental study and signifies that viscosity increase due to emulsification is an important mechanism of engineered water injections.

Published: May 2023

AbstractThe reliable use of ultrasonic metal welding requires a thorough understanding of the relevant bonding mechanisms. This article presents an approach to systematically investigate the relation between the mechanical properties and the interface of selected Al/Cu and Al/GFRP joints. The hypothesis is that the microstructure and tensile shear strength of the specimen can be related to their interface properties presented by contact stiffness and damage initiation traction. For this purpose, the mentioned hybrid material systems were ultrasonically welded using specific parameters to achieve defined levels of mechanical joint strengths. Micro sections and fracture surfaces were characterized to identify the interface geometry at certain strength levels. The main findings were different shares of bonded areas in the interface and characteristic micro geometries. Microscale finite element models of representative samples were developed to determine the stress and deformation behavior in the interface under tensile shear load and to compare the influence of the interface geometry on contact conditions to a simplified model. The simulations provide information about the influence of different damage initiation tractions and geometrical characteristics in the joints’ interfaces, as well as their contribution to the overall joint strength. For prospective industrial applications, they can serve as basis for further development of a contact model on component scale.

Abstract3D printing as a tool for prototyping is already well established in many areas of biotechnology. Whether for the production of individual laboratory devices, for the development of biocompatible devices for cell cultivation or even lab-on-a-chip systems for miniaturization and reduction of consumables – the technology is now used by many research areas within biotechnology. However, there is one area where 3D printing is still comparatively underutilized: chromatography. Here, we explain the potential and possible applications of 3D printing for the development of miniaturized chromatography systems.

AbstractBackgroundPostsurgical thoracic aortic pseudoaneurysms (PTAPs) are a potentially lethal complication after cardiac or aortic surgery. Surgical management can pose a challenge with high in-hospital mortality rates. Transcatheter closure is a less-invasive alternative treatment option for selected patients, although current experience is limited.AimsWe aimed to evaluate procedural and imaging outcomes of our first 11 cases of transcatheter PTAP closure with the use of closure devices.MethodsPatients with a high operative risk who underwent transcatheter PTAP closure at our centre from 2019 to 2021 were retrospectively included. Suitability was evaluated on preprocedural computed tomography (CT) scans and three-dimensional (3D) reconstructions. All procedures were performed in the catheterisation laboratory. Intraprocedural aortography and postprocedural CT scans with 3D reconstructions were used to evaluate PTAP occlusion.ResultsEleven consecutive patients with a high operative risk and a history of cardiac/aortic surgery who underwent transcatheter PTAP closure were included. PTAPs were predominantly located at the proximal or distal anastomosis of a supracoronary ascending aortic vascular graft or Bentall prosthesis (82%). Implanted closure devices included Amplatzer Valvular Plug III (82%), Amplatzer septal occluder (9%) and Occlutech atrial septal defect occluder (9%). No periprocedural complications occurred. After device deployment, residual flow was absent on aortography in 64% and minimal residual flow was present in 36% of patients. Subtotal or total occlusion of the PTAP on follow-up CT ranged between 45% and 73%.ConclusionsAlthough subtotal or total occlusion of the PTAP was found at follow-up in only 45–73% of cases, transcatheter PTAP closure guided by preprocedural 3D reconstructions can offer a valuable minimally invasive primary treatment option for patients who otherwise would face a high-risk reoperation.
Comparative Analysis of the Effects of Five Pretreatment Methods on Morphological and Methane Yield of Groundnut Shells
Authors: Olatunji Kehinde O. , Madyira Daniel M. 
Published: May 2023

AbstractAgricultural residues have been identified as potential substrates for anaerobic digestion, which indicates them as alternative energy sources. But enzymatic hydrolysis of these residues has been observed as the rate-limiting step due to their recalcitrant characteristics. Therefore, pretreatment before anaerobic digestion is required to reduce the retention time and increase the methane yield. This study investigates the influence of thermal, alkali, acid, nanoparticle additive, and combined pretreatments on the methane yield of groundnut shells. The effect of pretreatment methods on the structural arrangement was investigated with scanning electron microscopy, X-ray diffraction, and Fourier transform infrared, and methane yield was investigated after anaerobic digestion at mesophilic temperature. The morphological analysis shows that all the treatment methods alter the microstructural arrangement of groundnut shells at varying degrees, except the particle size reduction, which does not significantly influence them. Cumulative methane yields of 222.92, 214.00, 171.02, 140.99, and 261.36 ml CH4/g VSadded were recorded for thermal, alkali, acid, nanoparticle additive, and combined pretreatment methods, which represents 112.77, 70.03, 40.18, and 159.85% improvement compared to the untreated substrate (100.58 ml CH4/g VSadded). Combined pretreatment was found to release the highest cumulative yield, and thermal pretreatment produced the least retention period. Therefore, combined and thermal pretreatments could be a bright means to deconstruct the recalcitrant characteristics of lignocellulose feedstocks arrangement to reduce the retention period and improve the methane yield. These methods can be experimented with further at the industrial scale to establish economic viability.

Published: May 2023

AbstractDurability and affordability are two main reasons for the widespread consumption of plastic in the world. However, the inability of these materials to undergo degradation has become a significant threat to the environment and human health To address this issue, bioplastics have emerged as a promising alternative. Bioplastics are obtained from renewable and sustainable biomass and have a lower carbon footprint and emit fewer greenhouse gases than petroleum-based plastics. The use of these bioplastics sourced from renewable biomass can also reduce the dependency on fossil fuels, which are limited in availability. This review provides an elaborate comparison of biodegradation rates of potential bioplastics in soil from various sources such as biomass, microorganisms, and monomers. These bioplastics show great potential as a replacement for conventional plastics due to their biodegradable and diverse properties.
On Social Media Design, (Online-)Time Well-spent and Addictive Behaviors in the Age of Surveillance Capitalism
Authors: Montag Christian , Elhai Jon D. 
Published: May 2023

AbstractPurpose of the ReviewSocial media attracts billions of users worldwide, and research has investigated how screen time or time spent online is linked to well-being. Additionally, addictive-like behaviors towards the social media platforms are a focus of many studies. However, related research often neglects the simple fact that social media companies have willingly created immersive online environments with the aim to “persuade” users to spend as much time possible on their social media apps to watch ads and enlarge their digital footprints.Recent FindingsWe think that it is of utmost importance to better understand how the many design elements on social media platforms—ranging from the like-button to endless scrolling—impact the psyche and behavior of users. Such knowledge will not only help to better understand how problematic social media use evolves but will also provide important knowledge on how more healthy social media platforms could look like in the future. In this context, the present article also critically reflects the time well-spent initiative by the industry.SummaryFrom our view, the many problems around social media will only be solved if the data business model is abandoned. As long as companies base their business model on the digital surveillance of people’s lives, no changes towards healthier social media platforms can be expected.
A decoupling method for solving the multi-agent path finding problem

Published: May 2023

AbstractMany existing multi-agent path finding (MAPF) solvers focus on completeness, speed, or optimization. However, completeness and rapidity are usually in conflict with each other, which makes these algorithms far from satisfactory in practical applications. Motivated by this realistic requirement, we propose an efficient decoupling method to accelerate the solution of large MAPF problems. First, we define the concept of ‘non-essential vertex’-vertices which are not needed to solve a MAPF problem, and a scheme to identify them. Then, a decoupling scheme based on ‘non-essential vertex’ is proposed, which will assign higher priorities to agents whose goal positions are non-essential vertices and lower priorities to agents whose start positions are non-essential vertices. That is, invoking our decoupling algorithm can decouple any given MAPF problem into three subproblems while maintaining the completeness of the solution. All three sub-MAPF problems can be solved sequentially by a complete solver (e.g., CBS or EECBS, etc.), and two of them can also be solved by a prioritized planning algorithm. We have conducted several experiments in different workspaces, and the statistical results show that the proposed decoupling method significantly improves the speed and success rate of existing MAPF solvers with almost no degradation in solution quality when solving problems with high agent density. In addition, the solving efficiency can be further improved if the prioritized planning algorithm is invoked to solve the first and third sub-MAPF problems.

Published: May 2023

AbstractThe coronavirus pandemic identified a clinical need for pediatric tele-neuropsychology (TeleNP) assessment. However, due to limited research, clinicians have had little information to develop, adapt, or select reliable pediatric assessments for TeleNP. This preliminary systematic review aimed to examine the feasibility of pediatric TeleNP assessment alongside (1) patient/family acceptability, (2) reliability, and (3) the quality of the literature. Between May 2021 and November 2022, manual searches of PubMed, PsycINFO, and Google Scholar were conducted using terms related to “pediatric” and “tele-neuropsychology.” After extracting relevant papers with samples aged 0–22 years, predefined exclusion criteria were applied. Quality assessment was completed using the AXIS appraisal tool (91% rater-agreement). Twenty-one studies were included in the review, with reported qualitative and quantitative data on the feasibility, reliability, and acceptability extracted. Across included studies, TeleNP was completed via telephone/video conference with participants either at home, in a local setting accompanied by an assistant, or in a different room but in the same building as the assessor. Pediatric TeleNP was generally reported to be feasible (e.g., minimal behavioral differences) and acceptable (e.g., positive feedback). Nineteen studies conducted some statistical analyses to assess reliability. Most observed no significant difference between in-person and TeleNP for most cognitive domains (i.e., IQ), with a minority finding variable reliability for some tests (e.g., attention, speech, visuo-spatial). Limited reporting of sex-assigned birth, racialized identity, and ethnicity reduced the quality and generalizability of the literature. To aid clinical interpretations, studies should assess underexamined cognitive domains (e.g., processing speed) with larger, more inclusive samples.

Published: May 2023

AbstractAdvanced electromagnetic devices, as the pillars of the intelligent age, are setting off a grand transformation, redefining the structure of society to present pluralism and diversity. However, the bombardment of electromagnetic radiation on society is also increasingly serious along with the growing popularity of "Big Data". Herein, drawing wisdom and inspiration from nature, an eco-mimetic nanoarchitecture is constructed for the first time, highly integrating the advantages of multiple components and structures to exhibit excellent electromagnetic response. Its electromagnetic properties and internal energy conversion can be flexibly regulated by tailoring microstructure with oxidative molecular layer deposition (oMLD), providing a new cognition to frequency-selective microwave absorption. The optimal reflection loss reaches ≈  − 58 dB, and the absorption frequency can be shifted from high frequency to low frequency by increasing the number of oMLD cycles. Meanwhile, a novel electromagnetic absorption surface is designed to enable ultra-wideband absorption, covering almost the entire K and Ka bands. More importantly, an ingenious self-powered device is constructed using the eco-mimetic nanoarchitecture, which can convert electromagnetic radiation into electric energy for recycling. This work offers a new insight into electromagnetic protection and waste energy recycling, presenting a broad application prospect in radar stealth, information communication, aerospace engineering, etc.

AbstractThis memorial note for Professor Sanae-I Itoh presents her specific achievements in physics research alongside her wider record of accomplishment in the field of magnetically confined plasmas. The topics include bifurcation phenomena (e.g., H-mode and improved confinement modes), turbulence-generated structures (e.g., zonal flows and streamers), and fundamental concepts and processes in plasma turbulence (e.g. nonlinear couplings and energy transfer. The note focuses initially on results obtained through her integration of theory, simulation, and experiment, particularly those arising from a low temperature plasma facility at Kyushu University. We then describe contemporary challenges in plasma turbulence which Sanae addressed with great interest, and consider some of the perspectives that were opened by her achievements.
Analyses of fig (Ficus carica L.) leaves for virome profiling of mosaic diseased trees from the Western Cape Province (South Africa)
Authors: Bester Rachelle , van Niekerk Carla , Maree Hans J. 
Published: May 2023

AbstractVirus-like symptoms on fig tree leaves are a common occurrence worldwide and has mostly been attributed to fig mosaic disease (FMD). Even though only fig mosaic virus (FMV) has been shown to cause FMD, many other viruses have been identified in diseased fig trees. In 2021, total RNA was extracted from fig leaf samples displaying symptoms of mosaic and chlorotic mottling and was subjected to high-throughput sequencing (HTS) to construct the first virome profile of a South African fig tree. Bioinformatic analyses identified FMV, fig leaf mottle-associated virus 1 (FLMaV1), fig leaf mottle-associated virus 2 (FLMaV2), fig latent virus 1 (FLV1), fig badnavirus 1 (FBV1) and grapevine badnavirus 1 (GBV1) in the data. Reverse transcription polymerase chain reaction (RT-PCR) was conducted, for these viruses, on 24 additional fig leaf samples collected in the Western Cape. FBV1, GBV1, FMV, FLMaV1, FLV1, FLMaV2, and fig fleck-associated virus (FFkaV) were detected in 100%, 96%, 92%, 54%, 46%, 21%, and 12.5% of the samples, respectively. This is the first report on the presence of FMV, FLMaV2, FLV1, FFkaV, FBV1 and GBV1 in South Africa and offers a preliminary insight into the virus status of fig trees in the country.

Published: May 2023

Abstract
We have purified a novel caffeoylquinic acid named 3,4-di-O-caffeoylquinic acid isobutyl ester from the flower buds of Lonicera japonica Thunb., Caprifoliaceae. However, the biological function of 3,4-di-O-caffeoylquinic acid isobutyl ester is still unknown. Here, we found that 3,4-di-O-caffeoylquinic acid isobutyl ester effectively inhibited the proliferation and migration of hepatocellular carcinoma cells, and it displayed less toxicity to a normal liver cell line. Mechanistic studies showed that 3,4-di-O-caffeoylquinic acid isobutyl ester diminished the expression of YAP at the mRNA level. Overexpression of YAP significantly rescued HepG2 cells from the 3,4-di-O-caffeoylquinic acid isobutyl ester–induced suppression of proliferation and migration. Furthermore, the YAP downstream target gene CTGF was significantly repressed upon 3,4-di-O-caffeoylquinic acid isobutyl ester treatment, which was ameliorated by YAP overexpression. In addition, 3,4-di-O-caffeoylquinic acid isobutyl ester decreased the expression of β-catenin as well as CDK4/6. Collectively, 3,4-di-O-caffeoylquinic acid isobutyl ester exerts antihepatocellular carcinoma activity by inhibiting the YAP-CTGF pathway which controls the proliferation and migration of hepatocellular carcinoma cells. The Wnt/β-catenin pathway might be another pathway by which 3,4-di-O-caffeoylquinic acid isobutyl ester exerts antihepatocellular carcinoma activity. As a novel natural compound, 3,4-di-O-caffeoylquinic acid isobutyl ester might be a promising agent for hepatocellular carcinoma therapy.

Experimental and numerical evaluations of the bond behaviour between ribbed steel rebars and concrete
Authors: Biscaia Hugo C. 
Published: May 2023

Abstract
The study of interfacial behaviour between ribbed steel rebars and concrete is a subject that has been widely studied. However, the definition of the bond stress distribution throughout the embedded length of the steel rebar is still controversial due to the difficulty of experimentally obtaining such distribution for a fixed load magnitude. It is also undeniable its relevancy for the better understanding and model reinforced concrete (RC) structures. So, the definition of the local behaviour between the ribbed steel rebar and concrete is critical to correctly simulate the adherence between both materials. In this matter, the local bond-slip models recommended in codes seem to satisfy some researchers while others suggest prudence in using them. Therefore, only choosing the correct bond-slip relationship may lead to exact interpretations and conclusions of the structural behaviour of a concrete structure but with the existing different bond-slip types, researchers can be misled inadvertently. This work aims to clarify some of these aspects by numerically simulating several pull-out tests under different conditions and checking their influence (or not) on real-scale specimens. After the validation of the numerical model through a proposed new bond-slip relationship, other parameters were studied also. Although the type of the bond-slip relationship influences the detachment of the steel rebar from the concrete, the yielding of the former material was found to be the main parameter that masks the differences in the behaviour of real-scale RC structures when different types of bond-slip relationships were considered in the numerical simulations.
