Background

COVID-19 hesitancy among women planning to become pregnant, who are pregnant, and who are breast-feeding is still a global phenomenon. Unfortunately, there is a lack of national educational programs that provide those groups of people with the information they need about the vaccine.

Objective

This study investigated the effect of the COVID-19 vaccine tele-educational program on vaccine hesitancy and receiving the vaccine among women planning for pregnancy, pregnant and breast-feeding mothers.

Methods

This study implemented a quasi-experimental pre-post design and was conducted in Jordan. It was a two-time study and had two groups of women; 220 women participated in the control group, and 205 women participated in the intervention group (those received the tele-educational program). All participating women answered the demographic characteristics sheet and the Arabic version of Hesitancy About COVID-19 Vaccination Questionnaire twice.

Results

Results showed that after conducting the program the interventional group reported significantly higher vaccination rate and lower mean score of hesitancy than the control group (M = 24.67, SD = 5.11; M = 27.45, SD = 4.92; respectively) t (423) = -4.116, p-value < 0.001. Moreover, before the program, women in the intervention group reported significantly higher levels of hesitancy compared to those in the same group after the program (M = 28.35, SD = 4.91; M = 24.66, SD = 5.11; respectively) t (204) = 17.83, p-value < 0.001.

Conclusions

The study concluded that awareness of pregnant women after being given the tele-education program about COVID-19 vaccination decreased their hesitancy and improved their willingness to participate in the COVID-19 vaccination. Therefore, health workers should focus on providing scientific-based information about the vaccine to reduce the doubts of pregnant women about participating in the COVID-19.
Abiraterone-Docetaxel scheduling for metastatic castration-resistant prostate cancer based on evolutionary dynamics
Authors: Deris Atefeh , Sohrabi-Haghighat Mahdi
Published: March 2023

Patients with metastatic castration-resistant prostate cancer (mCRPC) are divided into three groups based on their response to Abiraterone treatment: best responder, responder, and non-responder. In the latter two groups, successful outcomes may not be achieved due to the development of drug-resistant cells in the tumor environment during treatment. To overcome this challenge, a secondary drug can be used to control the population of drug-resistant cells, potentially leading to a longer period of disease inhibition. This paper proposes using a combination of Docetaxel and Abiraterone in some polytherapy methods to control both the overall cancer cell population and the drug-resistant subpopulation. To investigate the competition and evolution of mCRPC cancer phenotypes, as in previous studies, the Evolutionary Game Theory (EGT) has been used as a mathematical modeling of evolutionary biology concepts.

Authors: Menekse Akin , Ertemel Adnan Veysel , Camgoz Akdag Hatice , Gorener Ali
Published: March 2023

For many different types of businesses, additive manufacturing has great potential for new product and process development in many different types of businesses including automotive industry. On the other hand, there are a variety of additive manufacturing alternatives available today, each with its own unique characteristics, and selecting the most suitable one has become a necessity for relevant bodies. The evaluation of additive manufacturing alternatives can be viewed as an uncertain multi-criteria decision-making (MCDM) problem due to the potential number of criteria and candidates as well as the inherent subjectivity of various decision-experts engaging in the process. Pythagorean fuzzy sets are an extension of intuitionistic fuzzy sets that are effective in handling ambiguity and uncertainty in decision-making. This study offers an integrated fuzzy MCDM approach based on Pythagorean fuzzy sets for assessing additive manufacturing alternatives for the automotive industry. Objective significance levels of criteria are determined using the Criteria Importance Through Inter-criteria Correlation (CRITIC) technique, and additive manufacturing alternatives are prioritized using the Evaluation based on Distance from Average Solution (EDAS) method. A sensitivity analysis is performed to examine the variations against varying criterion and decision-maker weights. Moreover, a comparative analysis is conducted to validate the acquired findings.

Published: March 2023

Background

The one-minute sit-to-stand-test (1-min STST) is a quick, space saving test to evaluate functional capacity. Exercise testing plays an important role in the long-term follow-up of pulmonary hypertension (PH) patients and is currently evaluated using the six-minute-walk-test (6MWT). The aim of the study was to assess the convergent validity of the 1-min STST in patients with PH and its association with markers of PH severity.

Methods

We evaluated 106 PH patients with the 1-min-STST and 6MWT and measured cardiorespiratory parameters (heart rate, blood pressure, oxygen saturation) before and after test conduction. N-terminal pro brain-type natriuretic peptide (NT-proBNP), WHO functional class (WHO-FC) and mean pulmonary artery pressure (mPAP) were defined as markers of PH severity.

Results

Strong correlation was found between performances of 1-min STST and 6MWT (r = .711,p< .001), indicating convergent validity. Both tests were inversely associated with NT-proBNP (STST: r = -.405,p< .001; 6MWT: r = -.358,p< .001), WHO-FC (STST: r = -.591,p< .001; 6MWT: r = -.643,p< .001) and mPAP (STST: r = -.280,p< .001; 6MWT: r = -.250,p< .001). Significant changes in cardiorespiratory parameters were observed in both tests (allp< 0.001). Further the post-exercise cardiorespiratory parameters correlated strongly between the 1-min STST and 6MWT (all r ≥ .651, allp< .001).

Conclusion

The 1-min STST demonstrated good convergent validity with the 6MWT and was associated with markers of PH severity. Furthermore, both exercise tests caused similar cardiorespiratory responses.

In this paper we use a contour integral method to derive a bilateral generating function in the form of a double series involving Chebyshev polynomials expressed in terms of the incomplete gamma function. Generating functions for the Chebyshev polynomial are also derived and summarized. Special cases are evaluated in terms of composite forms of both Chebyshev polynomials and the incomplete gamma function.
Comfort and vibration level of children in cycle carriers
Authors: Rothhämel Malte
Published: March 2023

This paper presents an analysis of comfort measurements taken in a bicycle trailer for transport of children. The vibration level was then compared to that in a cargo-trike and in a passenger car. The current research contributes to the rare literature on passenger comfort in bicycle trailers through measurements with accelerometer sensors between the seat in the trailer and a dummy representing an infant child. The varied parameters were the tyre inflation pressure, the driving velocity, as well as the additional load in the trailer. The results show a quite high weighted acceleration of 1 . . . 3 m s 2 on asphalt and 3 . . . 5 m s 2 on cobblestone pavement, which is similar to that in a compared cargo-trike but significant higher than the vibration level in the compared car.

Published: March 2023

In a previous rapid realist review (RRR) of international literature insight was provided into how, why, and under what circumstances person-centred care (PCC) in primary care works (or not) among others for people with low health literacy skills and for people with a diverse ethnic and socioeconomic background, by establishing a middle-range programme theory (PT), which describes the relationship between context items, mechanisms, and outcomes. Since the application of PCC in primary care in the Dutch setting is expected to differ from other countries, the objective of this study is to validate the items (face validity) resulting from the RRR for the Dutch setting by assessing consensus on the relevance of items. Four focus group discussions with patient representatives and patients with limited health literacy skills (n = 14), and primary care professionals (n = 11) were held partly combined with a Delphi-study. Items were added to refine the middle-range PT for the Dutch primary care setting. These items indicated that in order to optimally align care to the patient tailored supporting material that is developed together with the target group is important, next to providing tailored communication. Healthcare providers (HCPs) and patients need to have a shared vision and set up goals and action plans together. HCPs should stimulate patient’s self-efficacy, need to be aware of the patient’s (social) circumstances and work in a culturally sensitive way. Better integration between information and communications technology systems, flexible payment models, and patients access to documents, and recorded consultations should be in place. This may result in better alignment of care to the needs of patients, improved accessibility to care, improved patient’s self-efficacy, and improved health-related quality of life. On the long-term higher cost-effectiveness and a higher quality of healthcare can be realised. In conclusion, this study shows that for PCC to be effective in Dutch primary care, the PT based on international literature was refined by leaving out items and adding new items for which insufficient or sufficient consensus, respectively, was found.
A study of autoencoders as a feature extraction technique for spike sorting
Authors: Ardelean Eugen-Richard , Coporîie Andreea , Ichim Ana-Maria , Dînșoreanu Mihaela , Mureșan Raul Cristian
Published: March 2023

Spike sorting is the process of grouping spikes of distinct neurons into their respective clusters. Most frequently, this grouping is performed by relying on the similarity of features extracted from spike shapes. In spite of recent developments, current methods have yet to achieve satisfactory performance and many investigators favour sorting manually, even though it is an intensive undertaking that requires prolonged allotments of time. To automate the process, a diverse array of machine learning techniques has been applied. The performance of these techniques depends however critically on the feature extraction step. Here, we propose deep learning using autoencoders as a feature extraction method and evaluate extensively the performance of multiple designs. The models presented are evaluated on publicly available synthetic and real “in vivo” datasets, with various numbers of clusters. The proposed methods indicate a higher performance for the process of spike sorting when compared to other state-of-the-art techniques.
APSified OCT-angiography analysis: Macula vessel density in healthy eyes during office hours
Authors: Müller Meike , Schottenhamml Julia , Hosari Sami , Hohberger Bettina , Mardin Christian Y.
Published: March 2023

Purpose

Optical coherence tomography angiography (OCT-A) can visualize retinal capillary microcirculation non-invasively. In order to investigate potential factors influencing OCT-A diagnostics, the aim of the present study was to determine circadian changes in macular vessel density (VD) in healthy adults during office hours, considering axial length (AL) and subfoveal choroidal thickness (CT).

Methods

In the prospective study 30 eyes of 30 healthy subjects (mean age 28.7 ± 11.8, range 19–60 years) were recruited who underwent repeated measurements of AL, subfoveal CT and three-layer macula VD (superficial vascular plexus (SVP), intermediate capillary plexus (ICP) and deep capillary plexus (DCP)) on a single day at three predetermined timepoints (9 AM, 3 PM, and 9 PM). For better intra- and interindividual scan comparability, the new Anatomic Positioning System function (APS, part of Glaucoma Module Premium Edition [GMPE], Heidelberg Engineering, Germany) allowing analysis of identical retinal areas, was used for quantitative OCT-A analysis.

Results

Overall mean macula VD was unchanged during office hours in SVP, ICP and DCP, respectively (p>0.05). In addition, AL and CT showed no statistically significant changes over time (p>0.05). Rather, a large interindividual variance of VD with different peak time was observed. Contrary to the overall data, sectorial VD changed in dependency of office hours in all layers with an increase of VD in SVP between 9 AM and 9 PM (p = 0.003), in ICP between 3 PM and 9 PM (p = 0.000), in DCP between 9 AM and 9 PM (p = 0.048), and 3 PM and 9 PM (p = 0.000), respectively.

Conclusion

Overall mean macula VD, subfoveal CT and AL tended not to show statistically significant changes over time in this cohort, whereas a regional analysis of VD did. Therefore, a circadian influence on capillary microcirculation should be kept in mind. Moreover, the results highlight the importance of a more detailed analysis of VD in different sectors and different vascular layers. In addition, the pattern of diurnal variation could vary inter-individually, thus a patient-specific fluctuation pattern would need to be considered when evaluating these parameters in clinical practice.

Published: March 2023

Introduction

We aimed to investigate the predictors of relapse in immunoglobulin G4-related disease (IgG4-RD), focusing on the serum IgG4 levels during initial treatment.

Methods

We retrospectively recruited 57 patients with IgG4-RD who were treated with immunosuppressants and elevated serum IgG4 levels in a tertiary hospital between January 2011 and December 2020. They were followed up for ≥ 6 months after initiation of immunosuppressive therapy. Clinical and laboratory findings including serum IgG4 levels (reference value: 6–121 mg/dL) were compared between relapsed (n = 13) and non-relapsed (n = 44) groups. Multivariate Cox regression analysis was used to assess the predictors for relapse. We performed a Kaplan–Meier analysis with a log-rank test to evaluate the cumulative relapse rate for two years.

Results

Median serum IgG4 levels at baseline were 321 mg/dL in the relapsed group and 299 mg/dL in the non-relapsed group. Serum IgG4 levels were normalized after six months in five (38.5%) relapsed and 28 (63.6%) non-relapsed patients. In multivariate Cox regression analysis, the normalization of serum IgG4 levels at six months was associated with a lower risk of relapse, with a hazard ratio of 0.232 (p = 0.019). Central nervous system involvement was associated with the relapse, with a hazard ratio of 21.130 (p = 0.015). The cumulative relapse rate for two years was lower in the normal serum IgG4 group at six months than in the elevated serum IgG4 group at six months (p = 0.027).

Conclusion

Our study suggests that normalization of serum IgG4 levels during immunosuppressive treatment for IgG4-RD independently predicts relapse-free outcomes. Thus, monitoring serum IgG4 levels might be used as a marker of prognosis.
High-throughput phenotyping of infection by diverse microsporidia species reveals a wild C. elegans strain with opposing resistance and susceptibility traits

Published: March 2023

Animals are under constant selective pressure from a myriad of diverse pathogens. Microsporidia are ubiquitous animal parasites, but the influence they exert on shaping animal genomes is mostly unknown. Using multiplexed competition assays, we measured the impact of four different species of microsporidia on 22 wild isolates of Caenorhabditis elegans. This resulted in the identification and confirmation of 13 strains with significantly altered population fitness profiles under infection conditions. One of these identified strains, JU1400, is sensitive to an epidermal-infecting species by lacking tolerance to infection. JU1400 is also resistant to an intestinal-infecting species and can specifically recognize and destroy this pathogen. Genetic mapping of JU1400 demonstrates that these two opposing phenotypes are caused by separate loci. Transcriptional analysis reveals the JU1400 sensitivity to epidermal microsporidia infection results in a response pattern that shares similarity to toxin-induced responses. In contrast, we do not observe JU1400 intestinal resistance being regulated at the transcriptional level. The transcriptional response to these four microsporidia species is conserved, with C. elegans strain-specific differences in potential immune genes. Together, our results show that phenotypic differences to microsporidia infection amongst C. elegans are common and that animals can evolve species-specific genetic interactions.

Published: March 2023

Az egészségtudatos táplálkozás és életmód egyre fontosabb napjainkban. Ehhez elengedhetetlen a változatos étrend, a megfelelő minőségű és mennyiségű élelmiszerek fogyasztása, illetve a testmozgás a mindennapok során. Ezen felül fontos odafigyelni arra, hogy ételeink tartalmazzanak elegendő tápanyagot (fehérje, zsír, szénhidrát), ásványi- és nyomelemeket, illetve vitaminokat. Ilyen témában rengeteg információ található a közösségi felületeken, újságokban, szakirodalmakban. Azonban véleményünk szerint a rostfogyasztás jelentőségére nincs elég figyelem fordítva. Az emberi szervezet megfelelő funkcionálásához elengedhetetlen fontossággal bír az elegendő élelmi rost fogyasztása. Munkánk során kiemelten ezzel a témakörrel foglalkozunk, összpontosítva a magas rosttartalommal rendelkező zöldségek és gyümölcsök fogyasztására a magyar lakosság körében. Kutatásunk keretében kérdőíves felmérést készítettünk a rostfogyasztási szokásokat vizsgálva, külön kiemelve a zöldség-, és gyümölcsfogyasztási és vásárlási magatartást.

Effectiveness of Fenofibrate in Treatment-Naive Patients With Primary Biliary Cholangitis: A Randomized Clinical Trial
Authors: Liu Yansheng , Guo Guanya , Zheng Linhua , Sun Ruiqing , Wang Xiufang , Deng Juan , Jia Gui , Yang Chunmei , Cui Lina , Guo Changcun , Shang Yulong , Han Ying
Published: March 2023

INTRODUCTION:

Primary biliary cholangitis (PBC) is a progressive autoimmune liver disease, and patients with inadequate response to ursodeoxycholic acid (UDCA) treatment show reduced long-term survival. Recent studies have shown that fenofibrate is an effective off-label therapy for PBC. However, prospective studies on biochemical response including the timing of fenofibrate administration are lacking. This study is aimed to evaluate the efficacy and safety of fenofibrate in UDCA treatment-naive patients with PBC.

METHODS:

A total of 117 treatment-naive patients with PBC were recruited from the Xijing Hospital for a 12-month randomized, parallel, and open-label clinical trial. Study participants were assigned to receive either UDCA standard dose (UDCA-only group) or fenofibrate at a daily dose of 200 mg in addition to UDCA (UDCA-Fenofibrate group).

RESULTS:

The primary outcome was biochemical response percentage in patients according to the Barcelona criterion at 12 months. In the UDCA-Fenofibrate group, 81.4% (69.9%–92.9%) of patients achieved the primary outcome and 64.3% (51.9%–76.8%) in the UDCA-only group achieved the primary outcome (P = 0.048). There was no difference between the 2 groups in noninvasive measures of liver fibrosis and biochemical markers other than alkaline phosphatase at 12 months. Creatinine and transaminases levels in the UDCA-Fenofibrate group increased within the first month, then returned to normal, and remained stable thereafter until the end of the study, even in patients with cirrhosis.

DISCUSSION:

In this randomized clinical trial in treatment-naive patients with PBC, the combination of fenofibrate and UDCA resulted in a significantly higher biochemical response rate. Fenofibrate seemed to be well-tolerated in patients.

Published: March 2023

INTRODUCTION:

There has been increasing interest in artificial intelligence in gastroenterology. To reduce miss rates during colonoscopy, there has been significant exploration in computer-aided detection (CADe) devices. In this study, we evaluate the use of CADe in colonoscopy in community-based, nonacademic practices.

METHODS:

Between September 28, 2020, and September 24, 2021, a randomized controlled trial (AI-SEE) was performed evaluating the impact of CADe on polyp detection in 4 community-based endoscopy centers in the United States Patients were block-randomized to undergoing colonoscopy with or without CADe (EndoVigilant). Primary outcomes measured were adenomas per colonoscopy and adenomas per extraction (the percentage of polyps removed that are adenomas). Secondary end points included serrated polyps per colonoscopy; nonadenomatous, nonserrated polyps per colonoscopy; adenoma and serrated polyp detection rates; and procedural time.

RESULTS:

A total of 769 patients were enrolled (387 with CADe), with similar patient demographics between the 2 groups. There was no significant difference in adenomas per colonoscopy in the CADe and non-CADe groups (0.73 vs 0.67, P = 0.496). Although the use of CADe did not improve identification of serrated polyps per colonoscopy (0.08 vs 0.08, P = 0.965), the use of CADe increased identification of nonadenomatous, nonserrated polyps per colonoscopy (0.90 vs 0.51, P < 0.0001), resulting in detection of fewer adenomas per extraction in the CADe group. The adenoma detection rate (35.9 vs 37.2%, P = 0.774) and serrated polyp detection rate (6.5 vs 6.3%, P = 1.000) were similar in the CADe and non-CADe groups. Mean withdrawal time was longer in the CADe group compared with the non-CADe group (11.7 vs 10.7 minutes, P = 0.003). However, when no polyps were identified, there was similar mean withdrawal time (9.1 vs 8.8 minutes, P = 0.288). There were no adverse events.

DISCUSSION:

The use of CADe did not result in a statistically significant difference in the number of adenomas detected. Additional studies are needed to better understand why some endoscopists derive substantial benefits from CADe and others do not. ClinicalTrials.gov number: NCT04555135.

Enhanced Rate of Heat Transfer through Periodic Triangular Array of Circular Cylinders Embedded in Porous Media
Authors: Jamshed S. , Dhiman A.
Published: March 2023

Heat transfer enhancement through porous media are of interest in many thermal applications. Forced convection through a triangular array of circular cylinders embedded in a fluid-saturated porous media has been investigated using extended Darcy Brinkman-Forchheimer momentum equations and Local Thermal Equilibrium (LTE) model. Detailed results are illustrated, for high permeability levels (Darcy number varied from 1/10³ to 1/10) and different cylinder spacings (0.7 ≤ φ ≤ 0.99) at Re = 100. It is anticipated that porous media would enhance heat transfer, but it emanates multiple order in pressure drop.
Reynolds Number Effect on the Leading-Edge Vortex Induced by Fish-Like Lambari Swimming
Authors: Macias M. M. , Oliveira T. F. , Brasil Junior A. C. P.
Published: March 2023

Traditionally, the literature about fish swimming focuses on investigating the fish trailing wake. However, recently, Borazjani and Daghooghi [1] reported that studying the leadingedge vortex generated during fish swimming is a crucial issue in biomechanics analysis, in the same direction that similar works about the flight of insects and birds. Thus, we investigate the leading-edge vortex induced by a fish-like lambari (Astyanax bimaculatus) swimming in a three-dimensional viscous flow and the force productions at different Reynolds and Strouhal number. Numerical simulations are carried out employing the URANS approach with turbulence closure model transition k-?-SST and a deformable mesh condition to the fish swimming. It is observed that the leading-edge vortex attached to the caudal fin increases the propulsive force at equilibrium configurations (thrust and drag balanced). Besides, at lower Reynolds numbers, it is noted that the vortex, once detached, travels more slowly in the wake, locating closer to the caudal fin due to the delay of fluid convection.
Numerical Determination of the Equivalent Sand Roughness for a Regular Surface Roughness (Cubes)
Authors: Malchow S. , Wurm F.-H. , Torner B.
Published: March 2023

The Discrete Porosity Method (DPM) is a time-efficient simulation method that can be used to determine the equivalent sand roughness of an arbitrary surface roughness. It has been successfully applied to an irregularly distributed roughness (cast iron surfaces) to estimate the equivalent sand grain roughness of these surfaces. However, the DPM method has not yet been applied to a regularly distributed surface roughness. In this paper, the DPM method is used to determine the equivalent sand roughness of a regular roughness shape in the form of a cube array. The results of channel flow simulations using the DPM method are compared with experimental data. After identifying the fully rough regime in the channel flow, the equivalent sand grain roughness of the cubes is determined and compared with available data from the literature.

The absorption of smaller particles by the dynamic layer and the resulting decrease in the filtration rate, also increase in pressure losses are analyzed in two filtration modes - with constant rate and head drop. A technological analysis was performed on a number of examples and the possibility of controlling the start time of the protective action of the specified layer due to the regulation of its formation was shown.
Investigation of the Impurity Transfer Process in the Boundary Layer above a Concave Wall
Authors: Rudnitskii A. , Rudnitska M. , Tkachenko L.
Published: March 2023

Numerical modeling of the behavior of passive particles (markers) in the boundary layer above a concave surface has been performed. It is shown that, under the influence of longitudinal vortices, they relatively quickly reach the upper boundary of the boundary layer above the tops of the “mushroom” structures. This indicates a significant intensification of heat and mass transfer processes in the presence of a system of longitudinal vortices. We note that the convective transport of a scalar admixture significantly exceeds its propagation under the action of molecular effects. It is important to note that the stems of the “mushroom” structures, along which the markers move away from the wall, are noticeably thinner than the flow region directed towards the wall. This explains the effect of increased heat transfer in the presence of Görtler vortices. It should be noted that the markers were introduced parallel to the transverse coordinate evenly along the segment. Over time, they are concentrated in "mushroom" structures with the same wavelength, and there are no markers between the structures, and the line of these markers becomes wavy with a period equal to the wavelength.
On Gravity Currents in Power-Law Cross-Section Channels : The Effect of Vegetation

Published: March 2023

We consider the propagation of gravity currents (GC), through an array of vertical obstacles, called vegetation, along channels of power-law cross-section (CS) shapes. We formulate a model and solve it numerically. Special attention is given to the similarity long-term behaviour of the current, for which the analytical solutions are available and compared to the numerical data.
The Influence of a Rotation Magnetic Field Symmetry on the Non-Sstationary Instability of a Liquid Flow in the Infinite Cylinder
Authors: Zibold A. F.
Published: March 2023

In linear statement the non-stationary instability of the axisymmetric flow of a viscous incompressible conducting liquid arising in infinitely long cylinder under the influence of the rotating magnetic field of any rotary symmetry is investigated. Calculation of critical parameters of a flow at which the primary azimuthal flow loses stability and Taylor’s or wavy vortices arise is executed. It is established, that wavy vortices can arise directly at the loss of stability of a primary flow, omitting the stage of Taylor’s vortices formation.

La cuantificación de la biomasa es esencial para estimar la dinámica de almacenamiento y fijación de carbono de los ecosistemas boscosos. En este estudio se determinó la fracción de carbono (Fc) de especies forestales de los bosques tropicales ubicados en los municipios de Quibdó, Unión Panamericana y Unguía en el departamento del Chocó, Colombia. Se establecieron seis parcelas permanentes de monitoreo (PPM) de 1 ha. Se caracterizó la composición florística por PPM, registrando los individuos con DAP ≥ 10 cm. Se seleccionaron las 39 especies de mayor peso ecológico y se determinó su Fc mediante el método de calorimetría. Se encontró una Fc promedio de 0.46 gr.cm-3 con rangos entre 0.43 y 0.48. Se registraron un total de 2841 individuos distribuidos en 260 especies y 207 géneros. Las especies con mayor peso ecológico fueron Prioria copaifera Griseb. y Perkia pendula (Willd.).  La Fc constituye una herramienta para estimaciones más precisas de carbono aéreo en bosques húmedos.

While many biological processes can be modeled by abstracting away the space in which those processes occur, some modeling (particularly at the cellular level) requires space itself to be modeled, with processes happening not in well-mixed compartments, but spatially-defined compartments. The SBML Level 3 Core specification does not include an explicit mechanism to encode geometries and spatial processes in a model, but it does provide a mechanism for SBML packages to extend the Core specification and add additional syntactic constructs. The SBML Spatial Processes package for SBML Level 3 adds the necessary features to allow models to encode geometries and other spatial information about the elements and processes it describes.
Das Problem nicht-körperlicher Raumhaftigkeit
Authors: Höntsch Andreas
Published: March 2023

The paper argues that Plessner’s theory of positionality can be traced back to Kant’s theory of predicabilia in the Critique of Pure Reason. Kant’s theory of predicabilia allows for the reformulation of Plessner’s distinction between the organic structure of the living body on the one hand and the positional unity of this living body on the other hand. This enables a concept of non-physical spatiality from which Plessner’s concept of the boundary can be derived. Therefore, Plessner’s theory of positionality competes neither with Kant’s transcendental epistemology nor with his anthropology but rather extends his philosophy of science. Plessner develops the conceptual specifics of living beings, supplementing Kant’s concept of matter as the specific object of physics.

Despite ample attention in the literature for alignment patterns and case frames more generally, we know very little about how these elements of grammar spread from one language to another in a contact situation. Achieving a better understanding of this will help explain areal patterns in alignment and grammatical relation marking. In this contribution, we zoom in on a contact situation in the foothills of North-West Amazon, where languages of the Quechuan and Tukanoan families are in contact, and where previous authors have suggested that grammatical relation marking shows many potential contact effects. We find that, despite the absence of loanwords, abstract lexico-grammatical information associated with individual lexical items may spread from one language to another, especially within the class of sensation predicates. These can be characterized as lexically driven diffusion patterns, without formal borrowing, consistent with an overall characterization of the area’s sociolinguistics as loanword-avoiding.

This work demonstrates the facilities offered by density functional theory (DFT) to calculate the molecular structural and spectral properties of tri-n-butyl phosphate (TBP) and its derivatives, namely, di-n-butyl phosphate (HDBP) and mono-n-butyl phosphate (H2MBP). The computed parameters including frontier molecular orbitals and HOMOLUMO transitions indicated the TBP has the lowermost total energy with a lager HOMOLUMO energy bandgap followed by HDBP and H2MBP. These outcomes in terms of reactivity and stability were reversed counting their dipole moments. The simulated spectra of FTIR and Raman suggested these techniques could be considered as powerful for qualitative analysis of these compounds.

In this study, hydrochar was obtained from chickpea stalk by hydrothermal method. Then, activated carbon was synthesized by chemical activation method using ZnCl2 activator in the presence of this hydrochar. The effects of parameters such as impragnation rate (hydrochar/ZnCl2), impragnation rate, activation temperature and activation time on activated carbon synthesis were investigated. The iodine number of the obtained activated carbon was determined and its characterization was performed by SEM, BET, FTIR measurements. It was determined that the highest iodine number of synthesized activated carbon was 734 mg/g under conditions of impragnation time (24 hour), impragnation rate (1/2), activation temperature (400 oC), and activation time (45 minutes). The BET surface area of the activated carbon with the highest iodine number was determined as 572 m2 /g. The methylene blue number of synthesized activated carbon and hydrochar were found as 105 mg/g and 45 mg/g, respectively.

The CIGS thin-film solar cells Solar cells are regarded as one of the most promising photovoltaic technologies. They have the advantage of fast and low-cost manufacturing by depositing several thin layers. In this work, a numerical simulation was made to compare the effect of different buffer layers (CdS, ZnS, ZnSe, and In2S3) on the performance of CIGS solar cells using Silvaco Tcad 2D software. The results show that each buffer layer influences the performance of the cell. Therefore, our results suggest that the ZnS material as a buffer layers has better performance for our cell (Jsc=37.0252mAcm2, Voc=1,281, FF=88,01 , ƞ=20,88).

Effect of Ni doping on ZnFe2O4 samples was prepared by a sol-gel auto-combustion method. The obtained samples were calcinated at 6000C. Then, the samples were characterized by powder X-ray diffraction, scanning electron microscopy, energy dispersive X-ray analysis, dielectric and magnetic properties. XRD results confirm the formation of a cubic spinel-type structure with an average crystallite size decreased with Ni concentration from 33.68 to 31 nm. Lattice parameter decreases with increasing Ni concentration, due to the small ionic radius of the Ni2+ ion. The SEM images show the morphology of the samples as spherical shaped particles in agglomeration. The dielectric constant and magnetization showed an increasing trend with increasing Ni concentration due to the rearrangement of cations at tetrahedral and octahedral sites.
