Published: June 2024

Abstract
Background Dental pulp-derived mesenchymal stem cells (DPSCs) are documented to be a promising source for the treatment of a diverse spectrum of diseases including type 2 diabetes mellitus (T2DM). However, alterations in the characteristics of DPSCs from the T2DM patients are still unclear.
Objective The purpose of this study was to compare the characteristics of dental pulp stem cells obtained from diabetic and nondiabetic healthy individuals.
Methods Dental pulp stem cells from nondiabetic (ND-DPSCs) and diabetic (D-DPSCs) were isolated by the explant culture method. Both cells were expanded in identical culture conditions and subsequently differentiated into osteogenic, chondrogenic, and adipogenic conditions. D-DPSCs and ND-DPSCs were characterized for a panel of MSCs-specific surface markers. Senescence associated with β-galactosidase was performed. In addition, we also performed an in vivo chick embryo yolk sac membrane assay for angiogenesis.
Results Findings of this study showed that diabetes mellitus affected the osteogenic and chondrogenic differentiation, while adipogenic differentiation was significantly higher in D-DPSCs as compared to ND-DPSCs. Clonogenic ability and angiogenic potential of ND-DPSCs is higher than D-DPSCs despite similar surface marker expressions.
Conclusion Diabetes affects the stemness of D-DPSCs in terms of clonogenic, osteogenic, and chondrogenic differentiation and angiogenic potential, reflecting the adverse effects of hyperglycemia even on dental pulp stem cells.

AbstractThe purpose of this study is to understand the impact of community mobilization initiatives on citizens’ health-seeking behavior through the lens of COVID-19 vaccination in the state of Madhya Pradesh, India. This study follows a case study approach to understand community mobilization initiatives that led to increased COVID-19 vaccination uptake. The study delineates the process to increase community mobilization to improve the uptake of COVID-19 vaccination. It highlights the key components of community mobilization that were adopted: the involvement of local leadership (at district, block, and village level), support of vaccination/mobilizer team, the role of in-person communication, involvement of influential community heads and social workers, localized strategies and IEC materials, and support from the state administration. Additionally, the key communication themes that played a crucial role in increasing COVID-19 vaccination coverage are identified. The findings of this study will help the policymakers and practitioners in the domains of Health and Medical Humanities, Health Policy and Services, and Social Sciences to clarify the roles of community mobilization activities and initiatives in increasing vaccination coverage. Furthermore, the study provides evidence for the adaptation, integration, and enhancement of these activities based on the four case studies discussed.
A self-referenced optical phase noise analyzer for quantum technologies
Authors: Freund R. , Marciniak Ch. D. , Monz T. 
Published: June 2024

Second generation quantum technologies aim to outperform classical alternatives by utilizing engineered quantum systems. Maintaining the coherence required to enable any quantum advantage requires detailed knowledge and control over the noise that the hosting system is subjected to. Characterizing noise processes via their power spectral density is routinely done throughout science and technology and can be a demanding task. Determining the phase noise power spectrum in leading quantum technology platforms, for example, can be either outside the reach of many phase noise analyzers or prohibitively expensive. In this work, we present and characterize a low-complexity, low-cost optical phase noise analyzer based on the short-delay optical self-heterodyne measurements for quantum technology applications. Using this setup, we compare two ≈1 Hz linewidth ultra-stable oscillators near 729 nm. Their measurements are used as a baseline to determine and discuss the noise floor achieved in this measurement apparatus with a focus on limitations and their tradeoffs. The achieved noise floor in this all-stock-component implementation of an optical phase noise analyzer compares favorably with commercial offerings. This setup can be used particularly without a more stable reference or operational quantum system as a sensor as would be the case for many component manufacturers.
A triboelectric nanogenerator based on TPU/PVDF electrospinning for mechanical energy harvesting and monitoring running step rate
Authors: Zhou Huafeng 
Published: June 2024

Wearable fiber flexible sensors for sports motion monitoring have recently received attention. However, wearable flexible sensors still face limitations in material and device design. Here, we proposed a thermoplastic polyurethane (TPU)/polyvinylidene fluoride (PVDF) film as triboelectric material to manufacture triboelectric nanogenerator (TP-TENG) for harvesting mechanical energy and athlete step rate monitoring. The TPU/PVDF fiber film can be fabricated by using electrospinning technology. In addition, the role of negative triboelectric materials is played by TPU/PVDF film, and the nylon film acts as a positive triboelectric material. The TP-TENG device follows a single-electrode working mode, and it is easy to integrate into human clothing. The TP-TENG electrical output can achieve the maximum output when the content of PVDF in TPU/PVDF film reaches 15%. The TP-TENG can acquire the maximum output power of 699 µW under a 7 MΩ load. Also, the TP-TENG can be used as an electronic skin to achieve self-powered pressure sensing, and the sensitivity of the pressure sensor based on TP-TENG can reach 14.08 V N−1. By integrating it inside the shoes, TP-TENG can obtain the pace rate of runners for sports motion monitoring. This research reports an effective method for monitoring step rate in running and has potential application value.

Published: June 2024

Summary
This case study identifies the Sanur Village Festival’s (SVF) success factors as a community event. The Sanur Development Foundation, also known as Yayasan Pembangunan Sanur (YPS) in Bahasa, established the SVF in 2006 following the second Bali Bombing in 2005. The first Bali Bombing in 2002 led to a decrease in tourist numbers, and the same effect was observed after the second Bali Bombing in 2005. Sanur is one of the tourist destinations in Bali whose income relies heavily upon tourists and was affected by both incidents. Therefore, YPS created the SVF to show that Bali, particularly Sanur, is safe to visit and to increase the number of tourists after the incidents. The discussion provided in this case study is based on semi-structured interviews with three interviewees who are Sanur locals. This case shows that leadership, community participation, the organizers, funding, volunteers, booths and activities, location, and safety contributed to the success of the SVF.

Among different numerical methods for modeling turbulent flow, Reynolds-averaged Navier–Stokes (RANS) is the most commonly used and computationally reasonable. However, the accuracy of RANS is lower than that of other high-fidelity numerical methods. In this work, the uncertainties associated with the coefficients of the standard

Ill-posedness of time-dependent inverse problems in Lebesgue-Bochner spaces
Authors: Burger Martin , Schuster Thomas , Wald Anne 
Published: June 2024

Abstract
We consider time-dependent inverse problems in a mathematical setting using Lebesgue-Bochner spaces. Such problems arise when one aims to recover parameters from given observations where the parameters or the data depend on time. There are various important applications being subject of current research that belong to this class of problems. Typically inverse problems are ill-posed in the sense that already small noise in the data causes tremendous errors in the solution. In this article we present two different concepts of ill-posedness: temporally (pointwise) ill-posedness and uniform ill-posedness with respect to the Lebesgue-Bochner setting. We investigate the two concepts by means of a typical setting consisting of a time-depending observation operator composed by a compact operator. Furthermore we develop regularization methods that are adapted to the respective class of ill-posedness.
Rolling bearing fault diagnosis in electric motors based on IDIG-GAN under small sample conditions
Authors: Song Xiangjin , Liu Zhicheng , Wang Zhaowei 
Published: June 2024

Abstract
The bearing fault diagnosis based on deep learning algorithms requires a substantial amount of data. However, in practical industrial production, the diagnostic algorithms tend to work ineffectively due to the limitations of samples. Therefore, in this article, we propose an improved method of deep convolutional generative adversarial networks (DCGAN) with discriminator gradient gap regularization (IDIG-GAN), which can effectively solve the problems of unstable training and poor training performance under a small sample dataset. Firstly, the self-attention mechanism is integrated into the DCGAN to capture global information to enhance the generalization capability of the network. Moreover, gradient normalization is applied to the discriminator to address the problem of vanishing gradients in the network. Furthermore, gradient gap regularization is incorporated into the loss function to narrow the gap between the discriminator gradient norms, thereby improving network stability when dealing with small fault datasets. Through training with the improved IDIG-GAN, then the generated samples are used to expand the dataset and construct a fault diagnosis model. By verifying under two bearing datasets, the results demonstrate that the proposed method can generate high-quality samples and effectively enhance the diagnostic capability of the network when working with small datasets.

Published: June 2024

Abstract
In the realm of photovoltaic applications, scientists and technocrats are striving to maximize the solar cell input photon energy conversion to electricity. However, achieving optimal cell efficiency requires significant time and energy investment for each variation and optimization. To overcome this issue authors simulated and studied the fabricated cell for optimizing conditions, which can save time and efforts for the relatively better outcomes. The family of transition metal chalcogenides holds promise as a material that yield improved outcomes in optoelectronic applications, particularly in photovoltaics. These materials are employed in experimental investigations aimed at enhancing solar cell parameters, resulting in the development of the FTO/ZnO/ZrS2/MoS2/CuO/Au composite cell. Numerical simulations utilizing SCAPS-1D software is conducted, focusing on the significance of CuO as a hole transport layer (HTL), and ZnO as an electron transport layer (ETL). The investigation examines into the impact of various factors, including thickness, bandgap, and carrier densities for both HTL and ETL, on fundamental solar cell parameters. The study indicates that device parameters are influenced by factors such as recombination rate, photogenerated current, charge carrier length, and built-in-voltage. Optimized parameters for HTL, including thickness, bandgap, and carrier concentration, are determined to be 0⋅35 μm, 1⋅2 eV, and 1⋅0 × 1020 cm–3, respectively. For ETL, the optimized parameters are found to be 0⋅05 μm, 3⋅1 eV, and 1⋅0 × 1018 cm–3, respectively. With these optimized parameters, the efficiency of the solar cell reached 20⋅64%, accompanied by open circuit voltage, short circuit current density, and fill factor values of 0.836 V, 36.021 mA⋅cm–2, and 68⋅54%, respectively. The simulated results indicate that addition of two extra layers and the use of efficient binary materials in heterojunction formation can effectively enhance device parameters, offering advantages such as low-cost and large-scale fabrication.
A DFT study on structural, electronic, and optical properties of cubic perovskite semiconductors InXF3 (X = Be and Ca) for optoelectronic applications
Authors: Mohammed Shoaib Hussain M , Kaleemullah N Syed , Ajay G , Mohamed Sheik Sirajuddeen M 
Published: June 2024

Abstract
First principles calculations were employed to study the structural, electronic and optical properties of Indium based cubic perovskite materials, specifically focusing on InBeF3 and InCaF3 compounds. The generalized gradient approximation Perdew–Burke–Ernzerhof (GGA_PBE) approximation and Tran–Blaha modified Becke–Johnson (TB-mBJ) approximations were used to study and compare the electronic and optical properties. The compound InBeF3 is predicted to have an indirect band gap of 2.51 eV in GGA_PBE and 2.96 eV in TB-mBJ. InCaF3 is found to have a direct wide band gap of 3.61 eV in GGA_PBE and 4.37 eV in TB-mBJ approximation. The partial density of states predicts the significance of In-5p and F-2p states in the conduction and valence bands, respectively. The dielectric constants decrease under the TB-mBJ approximation, with InCaF3 demonstrating lower values owing to its larger band gap. Optical activity analysis indicates transparency for both compounds with notable absorption peaks, suggesting potential applications in transparent coatings. Refractive indices decrease with photon energy, with values dropping below 1.0 in the TB-mBJ approximation, indicating superluminal behavior in wave propagation. The drop in refractive index value below1.0 is earlier for InCaF3 than InBeF3. Examination of the extinction coefficient reveals UV absorption peaks, indicating potential for optoelectronic applications. From this study it can be noticed that the compounds under study can be used for optoelectronic applications, supported by their predicted structural and optical properties study.
Nanosystems with potential application as carriers for skin depigmenting actives
Authors: Castro Natalia Ruben , Pinto Cristal Dos Santos C , Dos Santos Elisabete P , Mansur Claudia Regina E 
Published: June 2024

Abstract
Hyperpigmentation is a skin disorder characterized by excessive production of melanin in the skin and includes dyschromias such as post-inflammatory hyperchromias, lentigens, melasma and chloasma. Topical products containing depigmenting agents offer a less aggressive treatment option for hyperpigmentation compared to methods like chemical peels and laser sessions. However, some of these agents can cause side effects such as redness and skin irritation. Encapsulating these actives in nanosystems shows promise in mitigating these effects and improving product safety and efficacy. In addition, nanocarriers have the ability to penetrate the skin, potentially allowing for targeted delivery of actives to the affected areas. The most commonly investigated nanosystems are nanoemulsions, vesicular nanosystems and nanoparticles, in which different materials can be used to generate different compositions in order to improve the properties of these nanocarriers. Nanocarriers have already been widely explored, but it is necessary to understand the evolution of these technologies when applied to the treatment of skin hyperchromias. Therefore, this literature review aims to present the state of the art over the last 15 years on the use of nanosystems as a potential strategy for encapsulating depigmenting actives for potential application in cosmetic products for skin hyperchromia. By providing a comprehensive overview of the latest research findings and technological advances, this article can contribute to improving the care and quality of life of people affected by this skin condition.

Published: June 2024

Abstract
Unique properties possessed by transition metal dichalcogenides (TMDs) attract much attention in terms of investigation of their formation and dependence of their characteristics on the production process parameters. Here, we investigate the formation of TMD films during chemical vapor deposition (CVD) in a mixture of thermally activated gaseous H2S and vaporized transition metals. Our observations of changes in morphology, Raman spectra, and photoluminescence (PL) properties in combination with in situ measurements of the electrical conductivity of the deposits formed at various precursor concentrations and CVD durations are evidence of existence of particular stages in the TMD material formation. Gradual transformation of PL spectra from trion to exciton type is detected for different stages of the material formation. The obtained results and proposed methods provide tailoring of TMD film characteristics necessary for particular applications like photodetectors, photocatalysts, and gas sensors.
Global transonic solutions of hot-Jupiter model for exoplanetary atmosphere
Authors: Chou Shih-Wei , Huang Bo-Chih 
Published: June 2024

Abstract
In this paper, we make modifications to the original hot-Jupiter model, which addresses the problem of hydrodynamic escape for the planetary atmosphere. The model involves the Euler equation with gravity, tidal effect, and heat. We employ the generalised Glimm technique to prove the presence of transonic solutions to the problem. By adjusting the dilation of the characteristic fields, we enhance the accuracy of the Glimm–Goodman wave interaction estimates. This allows us to establish a more general admissible condition for stabilizing the generalised Glimm scheme. Additionally, we derive the exact relationship between the lower bound of the gas velocity in the subsonic state and the adiabatic constant of the gas. Under certain constraints on the transonic initial and boundary data, the limit of the approximation solutions represents an entropy transonic solution with bounded variations. Furthermore, we are able to determine the feasible hydrodynamical region directly from the equation itself, without the need for any additional state equation.
