Transformation Process and Thermal Performance Assessment of Burkina Faso’s Housing Typologies
Authors: Aguilar-Sanchez Maria , Almodovar-Melendo Jose-Manuel , Cabeza-Lainez Joseph
Published: May 2023

Burkina Faso is a sub-Saharan African country with a high poverty rate that has quadruplicated its population in the last half fifty years, that is, from 4.5 to 18 million inhabitants. Such demographic changes together with an intense migration process from rural areas to large cities, among other issues, are contributing to a rapid process of socio-cultural transformation. In this context, changes in both traditional and contemporary housing are analyzed and a complete ther-mo-hygrometric evaluation is carried out by processing significant data from on-site measure-ments to shed new light on the response of the said dwellings to the environmental and local cultural values. Results show that the introduction of land ownership linked to climate change and the increasing scarcity of natural resources are forcing native ethnic groups to modify their traditional ways of life, threatening their subsistence. Consequently, we can prove that the new building typologies are not in the least suitable for the climatic conditions nor the rich cultural heritage of Burkina Faso. This fact, negatively affects the possibility of revitalizing vernacular and environmentally-oriented solutions for the contemporary world and the necessary advance to-wards a more sustainable architecture.

Authors: Kim Heyone , Oh Sang Heon , Son Jae Hoon , Hwang Dong-Hwan
Published: May 2023

In this paper, feasibility of the initial alignment of the gyro-free inertial navigation system (GF-INS) is investigated. Initial roll and initial pitch are obtained as the conventional INS since centripetal acceleration is very small. Relation between initial heading and accelerometers’ outputs of the gyro-free inertial measurement unit (GF-IMU) is derived. It is determined from the relation whether initial heading can be obtained in 15 GF-IMUs which have been presented in research literatures. The relationship between the accelerometer errors of GF-IMU and the initial heading error is derived. When gyros are additionally attached in one axis or two axes of the body frame, it is investigated that initial heading can be obtained. The initial heading error is also calculated from the accelerometer errors and the gyroscope errors. The results show that the initial heading from only accelerometer outputs of the GF-IMU cannot be used in the GF-INS since the error is too large. It can also be seen from the results that the initial heading can be used in the GF-INS if two gyroscopes are additionally attached to the roll and pitch axes of the body frame.

Authors: Koblischka Michael Rudolf , Pust Ladislav , Chang Crosby Soon , Hauet Thomas , Koblischka-Veneva Anjela
Published: May 2023

The experimental data in the literature concerning the Paramagnetic Meissner Effect (PME) or also called Wohlleben effect are reviewed with the emphasis on the PME exhibited by metallic, s-wave superconductors. The PME was observed in field-cool cooling (FC-C) and field-cool warming (FC-W) m(T)-measurements on Al, Nb, Pb, Ta, in compounds like e.g., NbSe2, In-Sn, ZrB12 and others and also in MgB2, the metallic superconductor with the highest transition temperature. Furthermore, samples with different shapes like crystals, polycrystals, thin films, bi- and multilayers, nanocomposites, nanowires, mesoscopic objects and porous materials exhibited the PME. The characteristic features of the PME, found mainly in Nb disks, like the characteristic temperatures T1 and Tp and the apparative details of the various magnetic measurement techniques applied to obbserve the PME are discussed. We also show that PME can be observed with the magnetic field applied parallel and perpendicular to the sample surface, that PME can be removed by abrading the sample surface and that PME can be introduced or enhanced by irradiation processes. The PME can be observed as well in magnetization loops (MHLs, m(H)) in a narrow temperature window Tp<Tc, which enables the construction of a phase diagram for a superconducting sample exhibiting the PME. We found that the Nb disks still exhibit the PME after more than 20 years, and we present the efforts of magnetic imaging techniques (scanning SQUID microscopy, magneto-optics, diamond nitrogen-vacancy (NV)-center magnetometry, and low-energy muon spin spectroscopy, (LE-μSR)). Various attempts to explain PME behavior are discussed in detail. Especially, magnetic measurements of mesoscopic Al disks brought out important details employing the models of a giant vortex state and flux compression. Thus, we consider these approaches and demagnetization effects as the base to understand the formation of the paramagnetic signals. New directions for further experimental and theoretical analysis are also outlined.

Authors: Kaparapu Jyothi
Published: May 2023

Fermentation is the oldest method used globally to process and preserve food while enhancing its nutraceutical profile. Alga-based fermented products have freshly been produced and tested due to rising curiosity in healthy supportable diets, which stresses the progress of advanced methods in food manufacture, functioning for both human health and Earth sustainability. Current applications have attention on the existence of numerous composites, including polyphenols and polyunsaturated fatty acids, that are treasured for food and pharmaceutical manufacturing. Both micro and macroalgae have expanded consideration as fermentation substrata, as they are measured as a maximum and acceptable basis of bioactive composites. Fermentation of microalgae has concentrated either on making biofuel or on procuring composites with bioactive assets, like antioxidant ability, antimicrobial capacity and anti-inflammatory probables. The objective of this review is to present a note on microalgae fermentation to acquire diverse valued composites with bioactive abilities. Furthermore, the methods of fermentation, species of algae employed in fermentation, fermentation circumstances, and bioactive properties of the derived bioactive composites have conversed.
Performance Improvement During Attitude Motion of a Vehicle Using Aerodynamic Surfaces based Anti-jerk Predictive Controller
Authors: Ahmad Ejaz , Youn Iljoong
Published: May 2023

This paper presents designing an attitude motion control strategy for a half-car model using an anti-jerk predictive controller. Anti-jerk predictive controller based on active aerodynamics surfaces is employed to deal with the anticipated future road maneuvers and improve vehicle ride performance by canceling out external jerks acting on the vehicle body. The body jerks are produced during vehicle traversing on a double lane-change maneuver, acceleration, or braking. The control strategy helps the vehicle to achieve a realistic operation of the active aerodynamic surface to improve the vehicle’s ride performance, i.e., ride comfort and road holding during cornering, acceleration, or braking. The anti-jerk predictive controller is developed based on the predictive control strategy, which predicts future road inputs and uses them to compensate for the vehicle’s attitude motion. The simulation results show that the proposed control strategy effectively reduces the effects of vehicle body jerks transmitted to the passengers, improving ride comfort without degrading vehicle handling. The anti-jerk predictive controller successfully tracks the desired attitude position by canceling the external body jerks.

Published: May 2023

In recent years, artificial intelligence technology has widely influenced the field of design, bringing new ideas to efficiently and systematically solve urban renewal design problems. The purpose of this study is to create a stylized generation technology for building facade decoration in historic districts, which will aid in the design and control of district style and form. The goal is to use the technical advantages of conditional generative adversarial network (CGAN) in image generation and style transfer to create a method for independently designing a specific facade decoration style by interpreting image data of historical district facades. The research in this paper is based on the historical district of Putian in Fujian Province, through an experiment of image data acquisition, image processing and screening, model training, image generation, and style matching of the target area. The research found that: (1) CGAN technology can better identify and generate the decorative style of historical districts. It can realize the overall or partial scheme design of the facade; (2) in terms of adaptability, this method can provide a better scheme reference for historical district reconstruction, facade renovation, and renovation design projects. Especially for districts with obvious decorative styles, the visualization effect is better. In addition, it also has certain reference significance for the determination and design of the facade decoration style of a specific historical building; (3) This method can better learn the internal laws of the complex district style and form so as to generate a new design with a clear decoration style attribute. It can be extended to other fields of historical heritage protection to enhance practitioners' stylized control of the heritage environment and improve the efficiency and ability of professional design.
Laboratory Tests Using Distributed Fiber Optical Sensors to Validated a Future Field Application for Strain Monitoring Pile

Published: May 2023

The use of fiber optics as a tool for different kinds of geotechnical monitoring can become highly attractive and cost effective when compared to conventional instruments such as piezometers, inclinometers, among others. A single fiber optic cable may cover a larger monitoring area compared to conventional instrumentation, and the possibility of monitoring more than one physical quantity with the same fiber optic cable. Consulting the literature, it is possible to find several different examples where distributed fiber optic systems are being used. For the use of any sensor, a calibration curve is required. In the case of strain sensors, calibration is required to derive strain values from the frequency measurement quantity. However, fiber optic sensor cable manufacturers often do not provide their own calibration parameters and consult the values in specialized literature, which can result in monitoring errors. In this context, this article presents a bench adjusted for tests on single mode fiber optic cables, as well as results of tensile tests aimed at defining the function of strain variations of two different optical fiber cables, manufactured by different companies, using two different distributed interrogators. This paper also proposes a methodology for calibrating of the fiber optic cables deformation since the calibration parameters are provided by the cable manufacturers, which can result in errors depending on the application. It should be noted that there are few manufacturers of fiber optic cables aimed at application in civil engineering. Therefore, with the calibration methodology proposed in this paper, it is intended to transmit to the academic community the possibility of obtaining calibration parameters of any fiber optic cable, even those manufactured for telecommunications purposes and not only for cables manufactured with the intended use in civil engineering. Because of this fact, researchers will not be restricted to the acquisition of special cables for their applications. Based on the results, it was possible to conclude that the application of calibrated fiber optic sensors in experimental piles foundations is viable, in order to evaluate the load-displacement behavior of these elements, under different loading conditions.

Simulational Tests of the Rouse Model
Authors: Phillies George
Published: May 2023

An extensive review of literature simulations of polymer melts is given, considering results that test aspects of the Rouse model in the melt. We focus on the mean-square amplitudes < (X_p(0))^{2} > and time correlation functions < X_p(0) X_p(t) > of the Rouse modes $X_p(t)$. Contrary to the Rouse model: (i) Mean-square Rouse mode amplitudes < (X_p(0))^2> do not scale as sin^{-2}(p \pi/2N), N being the number of beads in the polymer. For small p (say, p <= 3) < (X_p(0))^2> scales with p as p^{-2}$; for larger p it scales as p^{-3}. (ii) Rouse mode time correlation functions < X_p(t) X_p(0) > do not decay with time as exponentials; they instead decay as stretched exponentials exp(-a t^b)$. b depends on p, typically with a minimum near N/2 or N/4. (iii) Polymer bead displacements are not described by independent Gaussian random processes. (iv) For p not equal to q, < X_p(t) X_{q}(0) > is sometimes non-zero. (v) The response of a polymer coil to a shear flow is a rotation, not the affine deformation predicted by Rouse. Simulations thus conclusively demonstrate that the Rouse model is invalid in polymer melts. We also briefly consider the Kirkwood-Riseman polymer model.
Infantile Hypoxic Encephalopathy with Biphasic Seizures Mimicking Acute Encephalopathy with Biphasic Seizures and Late Reduced Diffusion (AESD)
Authors: Fujino Shuhei , Enokizono Mikako , Kono Tatsuo , Miyama Sahoko
Published: May 2023

Acute encephalopathy with biphasic seizures and reduced diffusion (AESD) is characterized by biphasic seizures following febrile viral infections and delayed reduced diffusion of the cerebral white matter on magnetic resonance imaging (MRI) diffusion-weighted imaging (DWI) (bright tree appearance, BTA). However, hypoxic encephalopathy with biphasic seizures and AESD-mimicking imaging findings has not been reported. Herein, we report an case of hypoxic encephalopathy due to suffocation with concomitant biphasic seizures and BTA, mimicking AESD. On day 1, a 5-month-old female was found face down with breathing cessation and deteriorating consciousness level. The electroencephalography (EEG) revealed periodic epileptic discharges, suggesting possible nonconvulsive status epilepticus. Despite the improvements in consciousness level and EEG abnormalities on day 2, her consciousness level deteriorated again with generalized tonic-clonic seizures on day 3, and head MRI-DWI revealed restricted diffusion predominantly in the subcortical areas, suggesting BTA. Treatment for acute encephalopathy resolved clinical sei-zures and EEG abnormalities. The persistence of abnormal EEG, reflecting abnormal excitation and accumulation of neurotoxic substances caused by hypoxia, may have contributed to the devel-opment of AESD-like findings. As hypoxic encephalopathy causes AESD-like biphasic seizures, monitoring the consciousness level, seizure occurrence, and EEG abnormalities even after acute symptoms have temporarily improved following hypoxia is essential.
Flexible Poled and Non-poled PVDF-based Plasmonic THz Sensor for the Detection of Dry Level in Hydrogel Lens

Published: May 2023

As the most commonly used hydrogel material in contact lenses, the amount of water in a lens affects its optical properties and comfort for the wearer. Therefore, an important challenge is to determine the safety and efficacy of contact lenses by accurately and non-destructively measuring the water content in real time. In this study, we demonstrate the accurate detection of water content in hydrogel contact lenses using a high-precision ATR format in a portable terahertz time-domain spectroscopy system. The technique can resolve small variations in the dielectric constant in solution, which is difficult to achieve with traditional transmission and reflection measurement modes. Information is obtained from the interaction between the sample and the swift waves propagating along the prism surface. The swift waves can excite longitudinal modes that are not directly accessible by conventional techniques. It is worth noting that the reference wave can be measured by removing the sample without disturbing the optical path. We also enhance the plasma effect at the interface with the hydrogel by using PVDF dielectric films of different polarities. We observed that the water content and refractive index changes in the ATR mode show different response patterns for nonpoled PVDF and poled PVDF membranes. This suggests that reflection and relative phase can be accurately evaluated in the THz-ATR technique, resulting in an accurate method for determining complex dielectric constants in the reflection geometry. This will allow accurate measurement of both surface and in vivo water content in hydrogels in the future and is a potential technical route for application in bioaqueous tissue measurements.
Life Origin in the Milky Way Galaxy: I. the Stellar Nucleogenesis of Elements Necessary for the Life Origin
Authors: Safronov Alexander N.
Published: May 2023

Chemical elements in space can be synthesized by stellar nuclear reactors. Studying the dynamics of processes occurring in the stars introduces a concept of the ensemble-averaged stellar reactor. For future interstellar missions, the terrestrial and solar abundances were compared with considerable number of stars allocated in the ~ 200 pc solar neighborhood. According to the value of the effective temperature, four stellar classes are distinguished, for which the correlation coefficients and standard deviation are calculated. The statement about the possibility of transferring heavy elements synthesized by stars over long distances in space has been completely refuted. There is no immutability of the distribution of elements on neighboring stars and in the Solar System. It is shown that chemical elements are mainly synthesized inside each stellar reactor. The theory of the buoyancy of elements is generalized to stars. It has been suggested that stars overheat due to a shift in the parameters of nuclear processes occurring inside stars, which leads to the synthesis of heavy elements.

Published: May 2023

Through the arrow decomposition of the Mueller matrix, respective sets of sixteen independent polarimetric images of biological tissues are obtained for enpolarizing, retarding and depolariz-ing descriptors. In addition to the mean intensity coefficient and the three indices of polarimetric purity, the absolute values and Poincaré orientations of diattenuation, polarizance, entrance re-tardance and exit retardance vectors are considered. In this work we use for the first time this set of polarimetric observables for the visualization of biological structures, both of animal and vege-tal origin. Results show images with enhanced visualization derived from the spatial variation of such significant polarimetric properties. The experimental results are discussed, showing the suit-ability of such set of observables for applications in biophotonics imaging, providing not only ex-cellent visualization of biological tissues, but also showing structures not visible in non-polarimetric images.
Model-Driven Analysis of ECG Using Reinforcement Learning
Authors: O’Reilly Christian , Oruganti Sai Durga Rithvik , Tilwani Deepa , Bradshaw Jessica
Published: May 2023

Modeling is essential to understand better the generative mechanisms responsible for experimental observations gathered from complex systems. In this work, we are using such an approach to analyze the electrocardiogram (ECG). We present a systematic framework to decompose ECG signals into sums of overlapping lognormal components. We used reinforcement learning to train a deep neural network to estimate the modeling parameters from ECG recorded in babies of 1 to 24 months of age. We demonstrate this model-driven approach by showing how the extracted parameters vary with age. After correction for multiple tests, 10 of 24 modeling parameters showed statistical significance below the 0.01 threshold, with absolute Kendall rank correlation coefficients in the [0.27, 0.51] range. We presented a model-driven approach to the analysis of ECG. The impact of this framework on fundamental science and clinical applications is likely to be increased by further refining the modeling of the physiological mechanisms generating the ECG. By improving the physiological interpretability, this approach can provide a window into latent variables important for understanding the heart-beating process and its control by the autonomous nervous system.

Published: May 2023

Photovoltaic(PV) power generation is highly nonlinear and stochastic. Accurate prediction of PV power generation plays a crucial role in grid connection as well as the operation and scheduling of power plants. To predict the PV power combination model, this paper suggests a method based on Empirical Mode Decomposition (EMD), Ensemble Empirical Mode Decomposition (EEMD), Complete Ensemble Empirical Mode Decomposition with Adaptive Noise (CEEMDAN), Nonlinear Auto-Regressive Neural Networks with Exogenous Input (NARXNN), Long Short Term Memory (LSTM) Neural Network, and Light Gradient Boosting Machine (LightGBM) algorithms. To attempt to reduce the non-smoothness of PV power, the weather variable features with the greatest effect on PV power are first identified by correlation analysis. Following this, the PV power modal decomposition is split and reorganized into a new feature matrix. Finally， a NARX is used to obtain preliminary PV power components and residual vector features， and the PV power is predicted by combining three models of LightGBM， LSTM, and NARX and then the final prediction results are obtained by combining the PV power prediction results using error inverse method weighted optimization. The prediction results demonstrate that the model put forth in this paper outperforms those of other models and validate the model's validity by utilizing real measurement data from Andre Agassi College in the United States.
Thermodynamics of Composition Graded Thermoelastic Solids
Authors: Cimmelli Vito Antonio
Published: May 2023

We propose a thermodynamic model describing the thermoelastic behavior of composition graded materials. The compatibility of the model with second law of thermodynamics is explored by applying a generalized Coleman-Noll procedure.

We calculate the speeds of coupled first- and second-sound pulses, propagating either trough nonequilibrium or trough equilibrium states. We characterize several different types of perturbations, depending on the value of the material coefficients.
Under the assumption that the deformation of the body can produce changes in its stoichiometry, altering locally the material composition, the possibility of propagation of pure stoichiometric waves is pointed out. Thermoelastic perturbations generated by the coupling of stoichiometric and thermal effects are analyzed as well.

Published: May 2023

Knee Osteoarthritis (KOA), the most common knee degenerative disease, involve a slow destructive process, leading to disability and ultimately total knee replacement. The progression of KOA is related to the loss of rheological properties of the synovial fluid (SF), due to slow immunological, inflammatory and enzymatic processes that cleave the hyaluronic acid (HA) and decrease the concentration of specific proteins. Since no effective treatments have been found to halt the progression of KOA, injection of HA-based viscoelastic gels combined with physiotherapy (PT) is an alternative to symptomatic therapies. In order to evaluate the effect of viscosupplementation and PT on the SF characteristics, the SF aspirated from the KOA was spectrophotometrically and rheological analyzed, comparing the receiving groups of HA Kombihylan® and groups that received Kombihylan® and complex PT. In patients treated with PT, SF extracted 6 weeks after viscosupplementation had a superior elastic moduli (G') and viscous moduli (G") profile behavior, having a homogeneous distribution of proteins and polysaccharides in the SF, stimulating stronger interactions. In the absence of PT the G' and G" profiles are non-uniform, suggesting an unorganized supplemented SF with some clustering phenomena, proteins aggregation and a low level of entanglement between HA and macromolecular components in the SF.

Authors: Inchaustegui Maria L. , Ruiz Kim , Gonzalez Marcos R. , Pretell-Mazzini Juan
Published: May 2023

Background:

Subtrochanteric pathological fractures (PFs) occur in approximately one-third of femur bone metastases. We seek to analyze surgical treatment strategies for subtrochanteric metastatic PFs and their revision rates.

Methods:

A systematic review was performed using the PubMed and Ovid databases. Reoperations as a result of complications were analyzed according to initial treatment modality, primary tumor site, and type of revision procedure.

Results:

We identified a total of 544 patients, 405 with PFs and 139 with impending fractures. The study population's mean age was 65.85 years with a male/female ratio of 0.9. Patients with subtrochanteric PFs who underwent an intramedullary nail (IMN) procedure (75%) presented a noninfectious revision rate of 7.2%. Patients treated with prosthesis reconstruction (21%) presented a noninfectious revision rate of 8.9% for standard endoprostheses and 2.5% for tumoral endoprostheses (p < 0.001). Revision rates because of infection were 2.2% for standard and 7.5% for tumoral endoprostheses. There were no infections within the IMN and plate/screws group (p = 0.407). Breast was the most common primary tumor site (41%) and had the highest revision rate (14.81%). Prosthetic reconstructions were the most common type of revision procedure.

Conclusion:

No consensus exists regarding the optimal surgical approach in patients with subtrochanteric PFs. IMN is a simpler, less invasive procedure, ideal for patients with a shorter survival. Tumoral prostheses may be better suited for patients with longer life expectancies. Treatment should be tailored considering revision rates, patient's life expectancy, and surgeon's expertise.

Authors: Dewi Pulung Sari Retno , Suryawati Nany
Published: May 2023

The legal system which is based on and inspired by the philosophical values of  Pancasila, aims to improve the legal system in Indonesia. That is able to protect its citizens from all actions or behaviors that are contrary to humanity and justice. Therefore, Indonesian law contains elements of protecting implementing order, justice, and especially non-discrimination, especially from gender. The law creates a dignified society, which humanizes humans, upholds human values. The norms that live in society, become a basis for the formation of a rule. But the customs and habits that exist in ethnic groups in Indonesia have their own character. Violence cannot be identified  in a particular society, but all humans can have a hard character. However, the existence of a belis or dowry, seems to give legitimacy that women have been bought. Therefore, through this community service activity, it focuses focuses on efforts to increase awereness of the law in the hope of minimizing the habit of violent behavior in the nomad community from Ende in the Surabaya city. This effort to increase awereness of the law is carried out through legal assistance regarding domestic violence in the Ende nomad community in Surabaya City. The assistance of representatives of Ende residents in Surabaya related to Law Number 23 of 2004 concerning Domestic Violence needs to be carried out intensively and massively. There is a decrease in the level of domestic violence in the families of Ende nomads in Surabaya.

A proposed safe design of the reverse osmosis system
Authors: Beltran Lezaun Maria Eugenia , Mangano Roberto , Puzzo Simone
Published: May 2023

In a seawater reverse osmosis (SWRO) desalination plant, the SWRO system includes the high-pressure pump, the high-pressure piping, the energy recovery equipment, the pressure vessels and the RO membranes. The membranes are the most delicate part of the plant and are subject to continuous operational variations during water production. Designers of plants propose various solutions to protect the RO system through the use of mechanical and control/automation devices. This paper aims to present several design and operational considerations and address them through a proposed technical solution. With the correct combination of instruments, the RO membranes are protected and the overpressure in the system can only happen due to malfunction or failure of the instruments.

Published: May 2023

Objective To identify the risk factors of bleeding at the puncture site after femoral artery puncture intervention by Meta-analysis, and to provide a basis for postoperative evaluation and prevention of bleeding at the puncture site.
Methods China National Knowledge Infrastructure (CNKI), Wanfang, VIP, China Biomedical Literature Service (CBM), PubMed, Medline, The Cochrane Library, EMbase and Web of Science were searched from the establishment of the database to October 10, 2022 Observational studies, including cross-sectional studies, case-control studies, and cohort studies, on risk factors for bleeding at the puncture site after transfemoral artery puncture intervention in the Science database. Newcastle-Ottawa scale (NOS) was used to evaluate the quality of the included studies. Finally, RevMan5.3 software was used for meta-analysis of the literature data.
Results Eight articles (total sample size 35250 cases) were included, including 1410 patients in postoperative bleeding group and 33840 patients in non-bleeding group. The influencing factors with statistically significant differences by meta-analysis are as follows: Elderly (OR=2.71, 95%CI = 2.17-3.38), female (R=4.26, 95%CI = 1.08-16.89), hypertension (OR=2.48, 95%CI = 1.69-3.63), obesity (OR=2.33, 95%CI = 1.59-3.42), Thrombolytic agents, anticoagulants, OR platelet antagonists were used (OR=2.95, 95%CI = 2.24-3.89), and manual compression was used (OR=6.78, 95%CI = 1.34-34.43).
Conclusions The evidence shows that advanced age, female, hypertension, obesity, the use of thrombolytic agents/anticoagulants/platelet antagonists and manual compression are the risk factors of bleeding at the puncture site after femoral artery puncture intervention, which can provide a reference for the risk assessment of bleeding after clinical surgery and the development of preventive measures.
Revisiting assumptions in test-negative studies for estimating vaccine effectiveness: the need for a clinical case definition

Published: May 2023

Test negative studies have been used extensively for the estimation of COVID-19 vaccine effectiveness (VE). Such studies are able to estimate VE against medically-attended illness under certain assumptions. Selection bias may be present if the probability of participation is associated with vaccination or COVID-19, but this can be mitigated through use of a clinical case definition to screen patients for eligibility, which increases the likelihood that cases and non-cases come from the same source population. We examined the extent to which this type of bias could harm COVID-19 VE through systematic review and simulation. A systematic review of test-negative studies was re-analysed to identify studies ignoring the need for clinical criteria. Studies using a clinical case definition had a lower pooled VE estimate compared with studies that did not. Simulations varied the probability of selection by case and vaccination status. Positive bias away from the null (i.e., inflated VE consistent with the systematic review) was observed when there was a higher proportion of healthy, vaccinated non-cases, which may occur if a dataset contains many results from asymptomatic screening in settings where vaccination coverage is high. We provide an html tool for researchers to explore site-specific sources of selection bias in their own studies. We recommend all group consider the potential for selection bias in their vaccine effectiveness studies, particularly when using administrative data.
Identifying Vaccine-hesitant Subgroups in the Western Pacific: A Latent Class Analysis
Authors: Choi Yongjin , Leung Kathy , Wu Joseph , Lin Leesa , Larson Heidi
Published: May 2023

Background: Vaccine hesitancy has seriously compromised the COVID-19 vaccine roll-out across the Western Pacific; nevertheless, evidence-based recommendations that account for the heterogeneity of vaccine-hesitant populations in this region remain lacking. To help design customized vaccine communication strategies, we sought to investigate the profile of the vaccine-hesitant populations in Cambodia, Japan, Lao PDR, Malaysia, Mongolia, Papua New Guinea, Philippines, Republic of Korea, and Viet Nam.
Methods: Using 16,408 survey responses from an international survey distributed in 2021 and 2022, we identified hidden subgroups by conducting latent class analysis (LCA) and examined their vaccine acceptance and booster uptake by using Ordinary Least Square (OLS) regressions.
Findings: Our LCA approach identified six classes: college students, distrusters of health care providers (HCPs), stay-at-home mothers, the elderly, compliant pragmatists, and general working population. Booster uptake were significantly low in two groups: college students [13 percentage points; 95% CI -0.21 to -0.05] and HCP distrusters [8 percentage points; 95% CI -0.15 to -0.01]; these groups’ acceptance were also similarly low. Stay-at-home mothers’ acceptance and uptake were comparable, but this group took a large portion of vaccine-hesitant people in the Philippines. The profiles of the vaccine-hesitant populations in each country were compared and categorized into four groups, depending on the composition of classes that account for the unvaccination population.
Interpretation: The results of this study suggest that drivers of vaccine hesitancy may vary by country and indicate that each country needs a customized strategy that reflects the profile of its vaccine-hesitant population. The proposed recommendations for each country can identify the target population for designing effective vaccine communication strategies.

Left Ventricular Diastolic Dysfunction is a hallmark of cirrhotic cardiomyopathy and has been linked to worse quality of life and outcomes in patients with end-stage liver disease. Its impact on survival after liver transplant is not known, especially using current diagnostic criteria to define LVDD. We performed a systematic review and metanalysis of current published literature on mortality after liver transplant in patients with left ventricular diastolic dysfunction. We searched for articles in PubMed, Scopus, EMBASE, Web of Science, and the COCHRANE Central database. We selected articles with adequate inclusion and exclusion criteria. Our primary outcome of interest was all cause mortality after liver transplant in relation to the presence of left ventricular diastolic dysfunction per the 2016 American Society of Echocardiography criteria. A total of 1029 articles were screened during the selection process. Two studies included in the metanalysis showed no significant difference on mortality, but heterogeneity was high. A narrative review of other studies that classified diastolic function with different criteria was also performed, finding association to worse outcomes in these patients. High quality prospective studies using current criteria are needed to corroborate these findings.

Budgeting in the public sector is an issue that numerous researchers in all countries are interested in. Therefore extensive research has been done on budgeting reforms, types, methods and models (such as, Performance-based Budgeting, Participatory Budgeting and, etc.). The present study also seeks to design a model of budgeting that provides a tool for measuring public budgeting in Iran that contain the components of Good Budgeting at each stage of the process (i.e. policy-making and formulation, implementation, approval and monitoring of the budget). Due to the complexity and extent of issues (economic, social and political) related to public budgeting, the use of new analytical methods is required for research in this field. Accordingly, the Total Systems Interventions approach (TSI) helped us to identify and select appropriate methodologies for recognizing and diagnosing the general budgeting system. Based on the results obtained from this approach, a Soft Systems Methodology (SSM) was selected to recognize the desired system. ​Consequently, Critical Systems Heuristic (CSH) and ​​​Viable System Model (VSM) were selected for its diagnosis. The combination of these methodologies in investigating the budgeting system, allowed that each of its subsystems were identified based on the VSM. Then, whit identification of the existing deficiencies, the research model was designed. Finally, this study provided a list of Good Budgeting components that were approved by experts in this field along with, suggestions for reform of the budgeting system and future research.
The statistical population of this research is experts in the field of system and budgeting in the Court of Accounts, the Plan and Budget Organization and members of the Parliament.
Data collection tools are in-depth semi-structured interviews with 16 experts.
Flexoelectricity and surface ferroelectricity in natural ice

The phase diagram of ice is complex and contains many phases, but the most common (frozen water at ambient pressure, also known as 1h ice) is a non-polar material despite individual water molecules being polar themselves1,2. Consequently, ice is not piezoelectric and does not generate electricity under pressure3. On the other hand, flexoelectricity (coupling between polarization and strain gradient) is allowed by symmetry in all materials4,5, and therefore ice may polarize under bending. Here we report the measurement of the flexoelectricity of ice and calculate its repercussions for ice-electrification processes occurring in nature. In addition, the sensitivity of flexoelectricity to surface boundary conditions has revealed the existence of a ferroelectric phase transition around 163 K in the surface “skin layer” of bulk natural ice.

Purpose:To investigate the function of AKAP2 in the pathogenesis of AIS by regulating the growth of chondrocyteand explore the mechanism involved.Methods:ATDC-5 cells was used as chondrogenic cell model, and the AKAP2 overexpression and knockdown plasmids were transinfected separately. The proliferation of the cells was tested with EdU and CCK-8 experiments, and the apoptosis was examined by flow cytometry. Subsequently, OE-NC and OE-AKAP2 were selected for RNA-seq and MeRIP-seq analyses to find differently expressed genes and RNA methylation peaks. . The expression of m6A methylases in OE-NC and OE-AKAP2 was then analyzed using a t-test. GSEA and KEGG enrichment analyses were performed to find out the concerning biological process and signals. The results of RNA-seq and MeRIP-seq were combined to seek the functional pathway.Results:AKAP2 knockdown significantly decreased the proliferation of ATDC-5 cells and increased the apoptosis rate, while the overexpression of AKAP2 functioned oppositely. A total of 1216 differentially expressed genes and 1193 differentially expressed peak genes were obtained in OE-AKAP2 group compared with OE-NC, and the expression of Rbm15b was significantly upregulated. Joint analysis of RNA-seq and MeRIP-seq showed that Rbm15b was significantly positively correlated with the cartilage-related gene CCN1. Moreover, GSEA and KEGG enrichment analyses showed that the WNT and NF-κB signaling pathways were significantly correlated to the overexpression of AKAP2 in ATDC-5 cells.Conclusion:Our findings suggest that AKAP2 overexpression promotes cartilage growth and development probably through upregulating Rbm15b in ATDC-5 cells and affecting the expression of CCN1, an important transcription factor in the WNT signaling pathway. This may account for the pathogenicity of AKAP2 variants in AIS to a certain degree.

Paludiculture, the productive use of wet or rewetted peatlands, offers an option for continued land use by farmers after rewetting formerly drained peatlands, while reducing the greenhouse gas emissions from peat soils. Biodiversity conservation may benefit, but research on how biodiversity responds to paludiculture is scarce. We conducted a multi-taxon study investigating vegetation, breeding bird and arthropod diversity at six rewetted fen sites dominated by sedges (Carex species) or cattail (Typha species). Sites were either wild, low- or high-intensity managed. Biodiversity was estimated across the range of Hill numbers using the iNEXT package, and species were checked for Red List status. Here we show that paludiculture sites can provide biodiversity value even while not reflecting historic fen conditions; managed sites had high plant diversity and had Red Listed arthropods and breeding birds. Our study demonstrates that paludiculture has the potential to provide valuable habitat for species even while productive management of the land continues.

Published: May 2023

In irrigation water management, it's critical to understand the infiltration rate and its properties. The study aimed to evaluate the ability of some empirical equations and Hydrus 1D models to predict soil infiltration and evaluate the effect of initial soil moisture content on infiltration characteristics. The experiment was conducted at Arba Minch demonstration farmland using a double-ring infiltrometer, and the performance of the various infiltration models (Horton’s, Philip’s, Kostiakov, and Modified Kostiakov) and Hydrus 1D were evaluated in the study area at five different initial water contents. The results showed that the Horton and Hydrus 1D models were fitted with the observed infiltration for the soil with three initial water contents (0.13, 0.256, 0.31, 0.354, and 0.375), and the goodness of fits was evaluated by R2 and RMSE with a range between 0.9967–0.997, 0.93–0.94 and 0.0054–0.006 and 0.024, respectively. Hence, Horton and Hydrus 1D, models could be used successfully to evaluate the cumulative infiltration of soil for the study area. Therefore, in this study, the Hydrus 1D model well captured the infiltration rates at different initial soil moisture contents.
