Authors: Patel Manushi J. , Som Narayan N. , Gupta Sanjeev K. , Gajjar P. N. 
Published: December 2023

AbstractFirst-principles methods have been employed here to calculate structural, electronic and optical properties of CsPbI3 and CsPbBr3, in monolayer and heterostructure (HS) (PbI2-CsBr (HS1), CsI-CsBr (HS2), CsI-PbBr2 (HS3) and PbI2-PbBr2 (HS4)) configurations. Imaginary frequencies are absent in phonon dispersion curves of CsPbI3 and CsPbBr3 monolayers which depicts their dynamical stability. Values of interfacial binding energies signifies stability of our simulated heterostructures. The CsPbI3 monolayer, CsPbBr3 monolayer, HS1, HS2, HS3 and HS4 possess direct bandgap of 2.19 eV, 2.73 eV, 2.41 eV, 2.11 eV, 1.88 eV and 2.07 eV, respectively. In the HS3, interface interactions between its constituent monolayers causes substantial decrease in its resultant bandgap which suggests its solar cell applications. Static dielectric constants of all simulated heterostructures are higher when compared to those of pristine monolayers which demonstrates that these heterostructures possess low charge carrier recombination rate. In optical absorption plots of materials, the plot of HS3 displayed a red shift and depicted absorption of a substantial part of visible spectrum. Later on, via Shockley-Queisser limit we have calculated solar cell parameters of all the reported structures. The calculations showed that HS2, HS3 and HS4 showcased enhanced power conversion efficiency compared to CsPbI3 and CsPbBr3 monolayers when utilized as an absorber layer in solar cells.

Abstract
Vitiligo is characterized by the development of white patches on the skin either due to the loss of functional melanocytes or perturbations in the melanogenesis pathway. In the present study, we investigated the therapeutic potential of herbo-mineral formulation, Melanogrit in neutralizing the white patches in the skin. The study utilized UPLC/MS-QToF technique to determine the diversified phytochemical profile in Melanogrit. The murine B16F10 cells when treated with Melanogrit underwent morphological changes, including increased angularity, enlarged cell size, and greater dendritic protrusions. To establish an equivalent model to study melanogenesis, we carefully optimized the dosage of α-melanocyte stimulating hormone (αMSH) in B16F10 cells as an alternative to using melanocyte-keratinocyte cocultures. The study determined a sub-optimal dose of αMSH (0.2 nM) in B16F10 cells that does not manifest any measurable effects on melanogenesis. In contrast, Melanogrit when used in conjunction with 0.2 nM αMSH, induced a dose-dependent increase in extracellular and intracellular melanin levels. Melanogrit transcriptionally up-regulated the decisive genes of the melanogenesis pathway, MITF, TYR, and TRP1, which was evident from the increased cellular tyrosine activity. Our findings also demonstrated that Melanogrit ameliorated the MITF protein levels by inhibiting pERK; notably without involving GSK3β in the process. Taken together, our findings strongly suggest that Melanogrit has the potential to stimulate melanogenesis, making it a promising candidate for clinical applications in the treatment of white skin patches that develop in vitiligo patients.
Alcoholes no vínicos para la mejora del desarrollo del velo de flor y de las características sensoriales de los vinos Finos de la D.O. Jerez-Xérèz-Sherry

Published: December 2023

Abstract
The wines produced in the Jerez-Xérès-Sherry Designation of Origin fall within the category of Fortified Wines, according to Regulation 1308/2013 of the European Parliament, which stipulates that they must be exclusively fortified with wine alcohol, with an acquired alcoholic strength between 95.0% and 96.0%. However, there are other alternative alcohols whose behavior is unknown but could be equally effective in the development of biological aging, with an impact on the final product quality and lower economic costs. This study examines the effect of using malt alcohols, grape pomace, agave, sugarcane, and cereal alcohols, as well as wine alcohols obtained through different distillation methods and at varying alcohol concentrations, for fortifying wines subjected to biological aging. The development of the "flor" yeast veil will be evaluated under each aging condition and isolated and characterized using molecular techniques. Additionally, the base wine fortified with the different alcohols will be monitored and analyzed both physicochemically and organoleptically.

Published: December 2023

Resumen
Algunos coproductos vitivinícolas se han utilizado para obtener extractos enriquecidos en (poli)fenoles con efectos antihipertensivos. Sin embargo, aún se desconoce si las lías de vino (LV) contienen compuestos antihipertensivos. Este estudio se centró en estudiar si las LV podría ser fuente de estos compuestos. Se evaluó la actividad antihipertensiva de cinco LV (fracción líquida, 5 mL/kg) en ratas hipertensas (SHR). Una de las LV mostró un fuerte efecto antihipertensivo, que se asoció con su alto contenido en flavanoles y antocianinas. La reducción del estrés oxidativo y mejora del estado redox y disfunción endotelial fueron algunos mecanismos involucrados en su bioactividad. Además, las LV se sometieron a extracción asistida por enzimas (Flavourzyme®), lo cual solubilizó compuestos fenólicos (57.20%) inicialmente no solubles. Ácido gálico, catequina y malvidina-3-glucósido fueron los principales (poli)fenoles de este hidrolizado. Además, el hidrolizado mostró una mayor actividad inhibitoria de la enzima convertidora de angiotensina, antioxidante y antihipertensiva que las LV. Los péptidos FKTTDQQTRTTVA, NPKLVTIV, TVTNPARIA, LDSPSEGRAPG y LDSPSEGRAPGAD, identificados en el hidrolizado, exhibieron actividad antihipertensiva en SHR (10 mg/kg). LV son una buena fuente de compuestos antihipertensivos con potencial para usarse como nutracéuticos o ingredientes funcionales. Esto permitiría la valorización de las mismas y contribuiría a la economía circular de la industria vitivinícola.

Authors: Panchenko Alexander Ivanovich , Mikhailov Vladislav Andreyevich 
Published: December 2023

This paper investigates the contact zone between the binder material, foam glass and its analogues such as block foam glass and sheet glass, using the detachment method. Data is presented on the detachment pattern and bond strength between the foam glass and the binder material, which in turn allows the quality of the contact zone to be assessed.
The results of research on the use of such binders as cement, gypsum and modified gypsum binder with the addition of amorphous silica and lime in foam glass concrete are presented. It is shown that the use of modified gypsum binder significantly increases the strength of bond of the aggregate (granulated foam glass) with the binder.
The obtained data can be used to improve the quality of the contact zone and, as a consequence, to increase the quality of expanded glass concrete.

Published: December 2023

Abstract
To address the problem of instability in phase retrieval, ptychography technology was introduced to intensity interferometry (II), called ptychography II imaging (PIII). The resolution of PIII system is limited by the size of detection aperture. However, large-aperture detector means high cost. In this paper, the concept of aperture synthesis is brought to PIII. We theoretically derive the periodicity of speckle pattern produced by PIII, which can help guide the system design. Our findings also suggested that discontinuous speckle patterns can still be used to reconstruct the image of object. Additionally, the aperture-synthesis-based PIII system was found to have stronger tolerance to intensity noise and could reconstruct images at low signal-to-noise ratios. Finally, by conducting simulations and experiments, we demonstrated the effectiveness of the aperture-synthesis-based PIII system. These results indicate that aperture synthesis is a valuable approach for enhancing the performance of PIII system.

Abstract
Monolayer blue phosphorene (BlueP) has attracted much interest as a potential channel material in electronic devices. Searching for suitable two-dimensional (2D) metal materials to use as electrodes is critical to fabricating high-performance nanoscale channel BlueP-based field effect transistors (FETs). In this paper, we adopted first-principles calculations to explore binding energies, phonon calculations and electronic structures of 2D metal-BlueP heterojunctions, including Ti3C2-, NbTe2-, Ga(110)- and NbS2-BlueP, and thermal stability of Ti3C2-BlueP heterojunction at room temperature. We also used density functional theory coupled with the nonequilibrium Green function method to investigate the transport properties of sub-5 nm BlueP-based FETs with Ti3C2-BlueP electrodes. Our calculated results indicate that Ti3C2-BlueP has excellent thermal stability and may be used as a candidate electrode material for BlueP-based FETs. The double-gate can more effectively improve the device performance compared with the single-gate. The estimated source leakage current of sub-5 nm transistors reaches up to 369 µA µm−1, which is expected to meet the requirements of the international technology roadmap for semiconductors for LP (low-power) devices. Our results imply that 2D Ti3C2 may act as an appropriate electrode material for LP BlueP-based FETs, thus providing guidance for the design of future short-gate-length BlueP-based FETs.

Published: December 2023

Abstract
Fringe projection profilometry (FPP) is a widely used non-contact 3D measurement method. Though maturing in the last decade, it remains a significant challenge when facing the phase unwrapping of measured object surfaces in a single-shot measurement setting. With the rapid development of deep learning techniques, the adoption of a data-driven approach is gaining popularity in the field of optical metrology. This study proposes a new absolute phase recovery method based on the devised single-stage deep learning network. The aim is to ensure high-quality absolute phase recovery from a single-shot fringe projection measurement. Unlike most existing approaches, where the numerators and denominators of the wrapped phases and the fringe orders are predicted in various stages, the proposed method acquires the wrapped phases and the corresponding fringe orders within a single network, i.e. it can predict both wrapped phases and the corresponding fringe orders directly and simultaneously from the single fringe pattern projected in the single-shot mode based on a unified Y-shaped network. Experiments on benchmark datasets and models have demonstrated the effectiveness and efficiency of the technique, especially in terms of high-quality recovery of absolute phase information by using the lightweight single-stage network, and enabling the FPP-based phase 3D measurements in an online manner.

Abstract
This work presents a high-performance surface plasmon resonance (SPR)-based biosensor for glucose detection. While adding a metal–organic framework layer, UiO-66, to the biosensor improves selectivity and enables direct detection without additional receptors, it does not significantly enhance sensitivity. A SPR-based biosensor is proposed to overcome this limitation by introducing a layer of 2D-transition metal dichalcogenides (2D-TMD) and decorating the UiO-66 structure with gold nanoparticles (UiO-66AuNP). The optical properties of the biosensor for glucose detection in urine are investigated by employing the finite difference time domain (FDTD) method with Kretschmann configuration at a wavelength of 633 nm, and its performance is effectively improved by incorporating 2D-TMD and AuNP layers into the biosensor structure. Notably, the SPR-based biosensor with the decorated UiO-66 layer exhibits a further change in the SPR angle in the presence of glucose-containing urine. Using computational studies, various performance parameters, such as the biosensors’ signal-to-noise ratio and quality factor, are evaluated in addition to sensitivity. The maximum sensitivity achieved is 309.3°/RIU for the BK7/Ag/PtSe2/WSe2/MoS2/UiO-66AuNP/sensing medium structure. The exceptional performance of the proposed biosensor structure demonstrates its suitability for precise glucose detection in urine while also opening new avenues for developing bioreceptor-free SPR-based sensors.
Dynamics of the flip long jump
Authors: Williams Hollis 
Published: December 2023

Abstract
The long jump is a track and field event in which athletes attempt to jump as far as possible from a take-off point into a sandpit. In the 1970s, an athlete called Tuariki Delamere tried to introduce a ‘front flip’ technique where one goes into a front tuck instead of using a regular technique like the hitch kick and argued that it would allow for a longer horizontal distance. Several reasons have been proposed for the superiority of this technique, including the reduction of drag force during flight and increased angular momentum at take-off. We show that the air resistance makes a negligible contribution to the horizontal distance covered whereas a larger angular momentum can increase the distance of a jump. We explain why the technique was banned and discuss whether our argument implies that the technique can be deemed to be superior in practice.
Focus stacking single-event particle radiography for high spatial resolution images and 3D feature localization

Published: December 2023

Abstract

Objective. We demonstrate a novel focus stacking technique to improve spatial resolution of single-event particle radiography (pRad), and exploit its potential for 3D feature detection. Approach. Focus stacking, used typically in optical photography and microscopy, is a technique to combine multiple images with different focal depths into a single super-resolution image. Each pixel in the final image is chosen from the image with the largest gradient at that pixel's position. pRad data can be reconstructed at different depths in the patient based on an estimate of each particle's trajectory (called distance-driven binning; DDB). For a given feature, there is a depth of reconstruction for which the spatial resolution of DDB is maximal. Focus stacking can hence be applied to a series of DDB images reconstructed from a single pRad acquisition for different depths, yielding both a high-resolution projection and information on the features’ radiological depth at the same time. We demonstrate this technique with Geant4 simulated pRads of a water phantom (20 cm thick) with five bone cube inserts at different depths (1 × 1 × 1 cm3) and a lung cancer patient. Main results. For proton radiography of the cube phantom, focus stacking achieved a median resolution improvement of 136% compared to a state-of-the-art maximum likelihood pRad reconstruction algorithm and a median of 28% compared to DDB where the reconstruction depth was the center of each cube. For the lung patient, resolution was visually improved, without loss in accuracy. The focus stacking method also enabled to estimate the depth of the cubes within few millimeters accuracy, except for one shallow cube, where the depth was underestimated by 2.5 cm. Significance. Focus stacking utilizes the inherent 3D information encoded in pRad by the particle's scattering, overcoming current spatial resolution limits. It further opens possibilities for 3D feature localization. Therefore, focus stacking holds great potential for future pRad applications.

Abstract
The distinct spin amplitude wave was reported in a highly frustrated magnetic compound Fe2GeO4, which is very different from observations on other members of the M2GeO4 (M = Fe, Co, and Ni) family, raising interest in this compound for some additional emergent phenomena. In particular, this non-uniform spin order allows the intrinsic connection between ferroelectric polarization and magnetically gradient structure to probe the potential linear magnetoelectric (ME) effect. In this work, we address this issue and investigate the magnetism of Fe2GeO4 single crystal that hosts two successive anomalies at antiferromagnetic (AFM) Néel temperatures T
N1 ∼ 7.5 K and T
N2 ∼ 6.7 K, respectively. Our results reveal a remarkable metamagnetic transition in the magnetization as a function of the magnetic field, occurring at a critical magnetic field H
c ∼ 4.1 T when applied along the [110] and [1–10] directions, while such transition along the [001] direction is pointedly absent. Further exploration uncovers two predominant off-diagonal ME coefficients αyz
and αzy
in the incommensurate AFM phase between T
N1 and T
N2. Additionally, all components of the linear ME tensor remain non-vanishing in the canting AFM phase below T
N2. This indicates the ME mechanisms for the two phases that may be driven by different magnetic structures. All these presented results are sufficient for us to draw a non-trivial ME phase diagram, which is beneficial to understanding the ME behavior of Fe2GeO4. Therefore, our study implies that Fe2GeO4, an unusual frustrated magnet, provides a platform for manipulating the fascinating ME effect in the spinel structure.

The calculations have been implemented with four different basis sets to see the effects of electron-exchange, electron-transfer channels, and continuum channels. The results are compared with those of experiments and other calculations.

Abstract
The combined impact of radiation and convection on the heat transfer of a wavy fin is scrutinized in the present analysis. The novelty of this research work is that it proposes a deterministic machine learning model known as an extreme learning machine to address the heat transfer problem of a wavy fin. The effect of radiation on convective heat transfer and the Rosseland approximation for the radiation heat exchange have been considered in the investigation. The nonlinear ordinary differential equation (ODE) is converted to its nondimensional form using the appropriate dimensionless variables. Runge-Kutta-Fehlberg's fourth-fifth order technique (RKF 45) is used to solve the nondimensional ODE numerically. The roles of convection-conduction, radiation-conduction, thermal conductivity, and radiation parameters have been discussed for satisfying a prescribed temperature distribution in rectangular and wavy fins with graphical visualization. A rise in convection-conduction and radiation-conduction variables decreased the thermal distribution of both the wavy fin and rectangular fin. Further, ANSYS simulation analyzes the variation of temperature and total heat flux in both rectangular and wavy fins. The study demonstrates the effectiveness of the model selected through the obtained results, which indicate the potential of the regression model for providing an accurate prediction.
Nutritional and health effects of bovine colostrum in neonates

Published: December 2023

Abstract
High concentrations of immunoglobulins, bioactive peptides, and growth factors are found in bovine colostrum (BC), the milk produced by cows in the first few days after parturition. Various biological functions make it increasingly used to provide nutritional support and immune protection to the offspring of many species, including humans. These biological functions include cell growth stimulation, anti-infection, and immunomodulation. The primary components and biological functions of colostrum were reviewed in the literature, and the authors also looked at its latent effects on the growth and development of neonates as well as on conditions such as infections, necrotizing enterocolitis, short bowel syndrome, and feeding intolerance. The importance of BC in neonatal nutrition, immune support, growth and development, and gut health has been demonstrated in a number of experimental and animal studies. BC has also been shown to be safe at low doses without adverse effects in newborns. BC supplementation has been shown to be efficient in preventing several disorders, including rotavirus diarrhea, necrotizing enterocolitis, and sepsis in animal models of prematurity and some newborn studies. Therefore, BC supplementation should be considered in cases where maternal milk is insufficient or donor milk is unavailable. The optimal age, timing, dosage, and form of BC administration still require further investigation.
