Abstract
The orchestrated activity of the mitochondrial respiratory or electron transport chain (ETC) and ATP synthase convert reduction power (NADH, FADH2) into ATP, the cell’s energy currency in a process named oxidative phosphorylation (OXPHOS). Three out of the four ETC complexes are found in supramolecular assemblies: complex I, III, and IV form the respiratory supercomplexes (SC). The plasticity model suggests that SC formation is a form of adaptation to changing conditions such as energy supply, redox state, and stress. Complex I, the NADH-dehydrogenase, is part of the largest supercomplex (CI + CIII2 + CIVn). Here, we demonstrate the role of NDUFB10, a subunit of the membrane arm of complex I, in complex I and supercomplex assembly on the one hand and bioenergetics function on the other. NDUFB10 knockout was correlated with a decrease of SCAF1, a supercomplex assembly factor, and a reduction of respiration and mitochondrial membrane potential. This likely is due to loss of proton pumping since the CI P
P
-module is downregulated and the P
D
-module is completely abolished in NDUFB10 knock outs.
Sensitivity analysis for causal decomposition analysis: Assessing robustness toward omitted variable bias
Authors: Park Soojin , Kang Suyeon , Lee Chioun , Ma Shujie 
Published: March 2023

AbstractA key objective of decomposition analysis is to identify a factor (the “mediator”) contributing to disparities in an outcome between social groups. In decomposition analysis, a scholarly interest often centers on estimating how much the disparity (e.g., health disparities between Black women and White men) would be reduced/remain if we set the mediator (e.g., education) distribution of one social group equal to another. However, causally identifying disparity reduction and remaining depends on the no omitted mediator–outcome confounding assumption, which is not empirically testable. Therefore, we propose a set of sensitivity analyses to assess the robustness of disparity reduction to possible unobserved confounding. We derived general bias formulas for disparity reduction, which can be used beyond a particular statistical model and do not require any functional assumptions. Moreover, the same bias formulas apply with unobserved confounding measured before and after the group status. On the basis of the formulas, we provide sensitivity analysis techniques based on regression coefficients andR2{R}^{2}values by extending the existing approaches. TheR2{R}^{2}-based sensitivity analysis offers a straightforward interpretation of sensitivity parameters and a standard way to report the robustness of research findings. Although we introduce sensitivity analysis techniques in the context of decomposition analysis, they can be utilized in any mediation setting based on interventional indirect effects when the exposure is randomized (or conditionally ignorable given covariates).

Abstract
This study has clarified various micro electro mechanical system (MEMS) processes performance evaluation based on MEMSolver simulation software. The spin time against final resist thickness for the spin coating of a thin film of photo resist and the oxidation time versus oxide thickness for silicone dioxide growth for <100> silicon in wet oxide are clarified. The diffusion profile for Boron after predeposition and drive in of dopants in silicon and the thickness of silicon dioxide mask for Boron diffusion are demonstrated. The dopant distribution resulting from ion implantation and drive in and the percentage of dose penetrating photo resist mask versus thickness of the mask are reported. The film stress versus the film thickness from wafer bow measurements, aluminum deposition rate against temperature using the electronic beam evaporator and the deposition rate of polysilicon versus silane partial pressure are reported. The etch rate of the thermal oxide against percentage concentration of KOH, the etch rate against the etchant temperature for silicon nitride in hot phosphoric acid, and the etch rate against the etchant temperature for the thermal oxide using buffered hydrofluoric acid (BOE) are outlined.

Abstract
Among the family of transition metal dichalcogenides, 1T-TaS2 stands out for several peculiar physical properties including a rich charge density wave phase diagram, quantum spin liquid candidacy and low temperature Mott insulator phase. As 1T-TaS2 is thinned down to the few-layer limit, interesting physics emerges in this quasi 2D material. Here, using scanning near-field optical microscopy, we perform a spatial- and temperature-dependent study on the phase transitions of a few-layer thick microcrystal of 1T-TaS2. We investigate encapsulated air-sensitive 1T-TaS2 prepared under inert conditions down to cryogenic temperatures. We find an abrupt metal-to-insulator transition in this few-layer limit. Our results provide new insight in contrast to previous transport studies on thin 1T-TaS2 where the resistivity jump became undetectable, and to spatially resolved studies on non-encapsulated samples which found a gradual, spatially inhomogeneous transition. A statistical analysis suggests bimodal high and low temperature phases, and that the characteristic phase transition hysteresis is preserved down to a few-layer limit.
Spectral peak areas do not vary according to spectral averaging scheme used in functional MRS experiments at 3 T with interleaved visual stimulation
Authors: Mumuni Abdul Nashirudeen , McLean John , Waiter Gordon 
Published: March 2023

Abstract
Brain response to visual stimulation can be probed quantitatively using functional magnetic resonance spectroscopy (fMRS), which relies on the blood oxygenation level dependent (BOLD) contrast mechanism. BOLD effect in fMRS is associated with changes in the areas, widths, and heights of the MR spectra. This study investigated the effect of spectral averaging scheme (NEX value) on BOLD changes in the spectra. Using a visual stimulus at 8 Hz in single and interleaved stimulation paradigms, the BOLD effects in spectra acquired from the occipital brain region of three healthy volunteers (mean age ± SD = 32.7 ± 3.5 years) were compared for two fMRS data sets acquired with two NEX values (“2” and “8”) available on a 3 T MR scanner. BOLD signal changes were estimated as percentage changes in spectral areas, heights, and widths of six cerebral metabolites and water using the SAGE software package (version 7). There was a general trend of lower BOLD effects with NEX = 8 in both stimulation paradigms. In the single stimulation paradigm, NEX = 8 was associated with significantly lower N-acetyl aspartate (NAA) spectral height (p = 0.03), creatine (p = 0.04) and choline (p = 0.02) spectral widths, and NAA (p = 0.03), water (p < 0.01), and glutamate (p = 0.02) spectral areas. In the interleaved stimulation paradigm, NEX = 8 was associated with significantly lower glutamate spectral height (p = 0.02), water (p = 0.03), and glutamine (p = 0.03) spectral widths, but there was no significant difference in all spectral areas between the two NEX values. Even though the two NEX values offered some differences in observable BOLD effects, their spectral areas were not significantly different in the interleaved visual stimulation experiments.

Published: March 2023

AbstractIn this special work, two types of material, which are undoped and Mn doped TiO2thin films, have been produced by spin coating technique, and then their structural, morphological and optical properties have been measured at different Mn doping rates. Four different doping ratios, undoped, 1, 3 and 5% Mn doped TiO2have been both experimentally and theoretically investigated and some significant enhancements have been reported. The results of X-ray diffraction (XRD) such as dislocation density, strain, and crystallite size have indicated that undoped, 1, 3 and 5% Mn doped TiO2thin films had the phase of anatase at 450 °C. It has been observed that the peak intensity of 3% Mn doped TiO2films has decreased compared to undoped and 1% Mn doped TiO2while the peak intensity has increased for 5% Mn doped TiO2. The refractive indices and dielectric coefficients of the undoped and Mn doped TiO2thin films have also been calculated. The undoped and Mn doped TiO2/p-Si heterojunction diodes has exhibited photosensitive behaviour in the illuminated environment. 1% Mn doped TiO2/p-Si heterojunction diode indicated the highest photocurrent. The electrical parameters of all diodes have been calculated and compared to the conventionalJ–Vand Norde methods. Additionally, 1% Mn doped TiO2/p-Si heterojunction diode has been modelled by using the SCAPS-1D program, andJphvalues have also been calculated based on the shallow donor density (ND). The experimental and theoreticalJphvalues of this diode were found to be compatible with each other.
Archaeoastronomy and the alleged ‘Stonehenge calendar’
Authors: Magli Giulio , Belmonte Juan Antonio 
Published: March 2023

AbstractIn a recent Antiquity article, Darvill (2022) proposed that the mid third-millennium BC Stage 2 sarsen settings of Stonehenge (comprising the Trilithon Horseshoe, Sarsen Circle and the Station Stone Rectangle) were conceived in order to represent a calendar year of 365.25 days—that is, a calendar identical in duration to the Julian calendar. In the present article, the authors argue that this proposal is unsubstantiated, being based as it is on a combination of numerology, astronomical error and unsupported analogy.

Published: March 2023

Abstract
Mineralogical and morphological characteristics of cementitious materials at the early stage of hydration primarily govern the performance and durability characteristics of concrete. Tricalcium aluminate (C3A) is one of the important phases of cement that primarily controls the initial setting. It plays a crucial role in producing tricalcium silicate in the manufacturing of portland cement, which is the dominant phase and is mostly responsible for strengthening and hardening the cementitious system. This necessitates a comprehensive review of C3A hydration, which provides the beneficial role of C3A at the early stage of hydration, and understanding the influence of other admixtures in a modified cementitious system. To this end, this paper presents a critical review of the hydration of C3A and its role during the early stage of hydration. Understanding the reaction mechanism in the presence of various forms of calcium sulfate through different proposed theories has also been critically reviewed. Additionally, admixtures such as accelerators, retarders, water-reducing dispersants, superplasticizers, and parameters like water/solid ratio on C3A grain, which affect the setting time and rheology, have also been thoroughly presented. Furthermore, the role of C3A in the formation of secondary ettringite and the factors that affect the durability of concrete are focused on.

Published: March 2023

Abstract
The reduction in the availability of materials traditionally used in paving, especially the asphalt binder, requires the development of innovative technologies that allow their total or partial replacement in road construction. This work aims to analyze the development and performance of an asphalt bio-emulsion to be used in chip seals, using a bio-binder partially replaced by petroleum plant sap. For this, a two-stage experimental program was developed. The first stage consisted of sap extraction and manufacture of the bio-binder and bio-emulsion, whereas the second phase involved the rheological characterization of these materials in the dynamic shear rheometer and adhesion tests with the binder bond strength (BBS) test. The results indicated that the addition of sap and the emulsification process of the binder reduced its stiffness and increased its phase angle. In terms of the multiple stress creep recovery test, the addition of sap generated changes only at low frequencies, causing the materials to exhibit similar behaviors. The BBS test shows that the material has a better performance than the conventional one. Therefore, according to the rheological analyses following the emulsion performance grade and adhesion tests, the suitability of the bio-emulsion can be verified for paving services with chip seals.

Abstract
The disposal of a large amount of bottom ash generated from the incineration of municipal solid waste has become the focus of research in solid waste and environmentalism. Using municipal solid waste incineration bottom ash (MSWI BA) to prepare mortar can not only solve the problem of insufficient natural river sand resources, but also play a role in treating a large amount of MSWI BA to alleviate urban pressures. In this study, macroscopic properties of mortar were systematically investigated by rheological, mechanical, and drying shrinkage tests, and the influence of MSWI BA on the internal pore structure and interfacial transition zone of mortar has been analyzed by mercury intrusion porosimetry (MIP), scanning electron microscope (SEM) and back scattered electron imaging (BSE). The results show that the rheological model of fresh mortar mixed with MSWI BA as fine aggregate is more consistent with the modified Bingham model, and its plastic viscosity decreases and then increases with the increase of MSWI BA, while the yield stress shows an increasing trend. The compressive strength and splitting tensile strength of mortar decrease with the increase of MSWI BA; the smaller the water-cement ratio and aggregate-binder ratio, the greater the strength loss. The incorporation of MSWI BA improves the flexural strength and compression-flexure ratio of M5/M10 mortar, and the splitting tensile strength of M5 mortar at 28 days is increased by 30 % with 20 % MSWI BA. Additionally, the incorporation of MSWI BA reduces the drying shrinkage properties of mortar and improves the volume stability. At the same time, it increases the number of pores above 50 nm inside the mortar and the content of ettringite at the interface.

AbstractThroughout the SARS‐CoV‐2 pandemic, limited diagnostic capacities prevented sentinel testing, demonstrating the need for novel testing infrastructures. Here, we describe the setup of a cost‐effective platform that can be employed in a high‐throughput manner, which allows surveillance testing as an acute pandemic control and preparedness tool, exemplified by SARS‐CoV‐2 diagnostics in an academic environment. The strategy involves self‐sampling based on gargling saline, pseudonymized sample handling, automated RNA extraction, and viral RNA detection using a semiquantitative multiplexed colorimetric reverse transcription loop‐mediated isothermal amplification (RT‐LAMP) assay with an analytical sensitivity comparable with RT‐qPCR. We provide standard operating procedures and an integrated software solution for all workflows, including sample logistics, analysis by colorimetry or sequencing, and communication of results. We evaluated factors affecting the viral load and the stability of gargling samples as well as the diagnostic sensitivity of the RT‐LAMP assay. In parallel, we estimated the economic costs of setting up and running the test station. We performed > 35,000 tests, with an average turnover time of < 6 h from sample arrival to result announcement. Altogether, our work provides a blueprint for fast, sensitive, scalable, cost‐ and labor‐efficient RT‐LAMP diagnostics, which is independent of potentially limiting clinical diagnostics supply chains.

Hrvatska nastava u inozemstvu organizira se od 90-ih godina prošloga stoljeća za djecu i mlade hrvatskih iseljenika u svrhu učenja i njegovanja materinskoga jezika i hrvatske kulturne baštine. Brojne su specifičnosti odgojno-obrazovanog djelovanja u okviru Hrvatske nastave u inozemstvu, međutim, u hrvatskoj se znanstvenoj i stručnoj literaturi vrlo malo pisalo o načinu organizacije i posebnostima koji takav oblik nastave nosi. Stoga će se u ovome radu prikazati okvir ustroja Hrvatske nastave u inozemstvu, a izdvajanjem poslova učitelja i koordinatora, kao nositelja Hrvatske nastave u inozemstvu, ukazati na sve njezine posebnosti.
Kako bismo zaključili o trenutnom položaju Hrvatske nastave u inozemstvu, u radu će se prezentirati i usporediti broj učitelja i nastavnih mjesta u zadnjih pet godina u svim zemljama gdje je ona organizirana. Dostupni podatci nadležnoga Ministarstva o broju nastavnih mjesta i učitelja otkrivaju porast broja nastavnih mjesta u Europi i svijetu, kao i porast broja učitelja u zadnjih pet godina, što dodatno naglašava važnost Hrvatske nastave u inozemstvu i potrebu pridavanja veće pozornosti takvoj nastavi ‒ kako od strane nadležnih institucija, tako i od znanstvenika, pa i šire javnosti.

Authors: Rocha Breno Padovezi , Lodi Paulo Cesar 
Published: March 2023

As geomembranas (GMs) são materiais sintéticos com baixa permeabilidade (em torno de 10-12 cm/s) utilizadas como barreiras impermeáveis em aterros sanitários e lagoas de estabilização. A avaliação de seu desempenho éfeita através de ensaios acelerados de compatibilidade química. Pelo fato destas serem fabricadas em bobinas, necessitam de emendas (soldas) em suas aplicações. Devido à sua resistência química, as GMs de polietileno (PE) são mais utilizadas. No entanto, as GMs de poli cloreto de vinila (PVC) também apresentam desempenho adequado em diversas aplicações, principalmente na utilização de aterros sanitários e contenção de resíduos que não contenham hidrocarbonetos. Pelo fato das GMs de PVC não possuírem um estudo mais detalhado na literatura técnica, este trabalho avaliou, por meio de ensaio acelerado, a resistência de emendas de GMs de PVC em contato com resíduo de cana-de-açúcar (vinhaça) e de aterro sanitário (chorume). Foram avaliados doistipos de emendas (alta frequência e fusão química) em GMs com espessuras de 1.0 e 2.0 mm. As amostras de emendas foram imersas em recipientes de aço inoxidável a uma temperatura de 50º C e, após 2, 4 e 6 meses de incubação, estas foram ensaiadas verificando-se a retenção das propriedades (resistência ao cisalhamento e descolamento) em função do tempo de exposição. Os resultados indicam que houve variação nos valores das propriedades considerando-se cada tipo de técnica de fabricação da emenda bem como do tipo de resíduo. A resistência ao descolamento nas emendas confeccionadaspela técnica de fusão química, por exemplo, apresentou diminuições consideráveis após os períodos de exposição.

Background. The success of surgical treatment of urethral strictures is often assessed in terms of the quality of urination and the patency of the urethral lumen. Despite the fact that this assessment is carried out according to the above parameters, it seems important to take into account such a possible complication as erectile dysfunction, which can significantly impair the patient’s quality of life. This is the difference in the perception of the success of the surgical intervention by the clinician and the patient.Aim. To determine the relationship between urethroplasty and the likelihood of erectile dysfunction in the postoperative period according to world literature.Materials and methods. The PubMed database was analyzed using the keywords: anterior urethroplasty, posterior urethroplasty, urethroplasty, sexual dysfunction, erectile dysfunction. All articles were reviewed by two independent authors for inclusion based on predetermined criteria. Among the included scientific papers are randomized controlled trials, systematic reviews.Results. Sixteen scientific papers with a total of 1476 patients were included in the final study. The decrease in erectile function after surgery in this meta-analysis is 3 %. The main factors influencing postoperative parameters were age and erectile function at the time of surgery.Conclusion. Most studies state that urethroplasty does not imply a significant impact on erectile function, however, they acknowledge that the occurrence of this complication affects the assessment of treatment outcomes among patients and the further impact on their quality of life, regardless of postoperative urinary function.
