AbstractDiabetes-related metabolic disturbances have a negative impact on oral health as well. The reciprocal relationship between periodontal health and glycemic management has been already established. Both these pose important concerns to public health, and need to be addressed carefully. Ayurveda, the Indian Traditional Medicine System, has dealt in detail with the pathophysiology and management of prameha (diabetes) as well as various oral diseases including dantamoola vyadhi (periodontal diseases). Interestingly, the causative factors for dantamoola vyadhi are greatly similar to those of prameha. Ayurveda propounds formulations such as triphala, which are reported to possess antihyperglycemic activity as well as antimicrobial activity. Hence, such formulations can prove helpful in the management of both these diseases. Considering the global upsurge in research on traditional medicines worldwide, it is the need of the hour to consider the role of Ayurveda in the oral health issues of diabetic patients. The present review discusses the Ayurvedic concepts of diabetes and periodontal health along with their management.
One Size Fits All? Employer Branding in Different Contexts

Published: January 2025

AbstractWith employer branding (EB), businesses aim to align their organizational norms with the norms of their current and prospective employees, and they explicitly communicate about the firm’s norms. Communication, however, carries different meanings depending on the context in which one operates. Also, the organizational norms may vary depending on the context, i.e., industry, different countries, and geographical context in which a firm operates. As such, the process of EB may be context-dependent, too. This study explores if and how EB is applied differently in different country and industry contexts. The analysis draws on a quantitative content analysis of 226 job vacancies targeted at highly educated graduates and professionals in IT, energy, and healthcare from the North of the Netherlands and comparable regions from Germany and Bulgaria. Our findings show that EB, as manifested in core values and distinctive characteristics, is not widely adopted in the vacancies we included in our analysis. When adopted, different values are emphasized depending on the context. General information and job-specific information are most frequent among all industries and countries. EB is a multidimensional concept with different dimensions used according to the context. The study’s main implication is that companies need to be mindful of the context in which an EB strategy is used. A one-size-fits-all approach in EB is likely not the most effective. This is particularly relevant for multinationals that adopt a worldwide organizational brand.

3D LiDAR SLAM for natural guided navigation of automated guided vehicles in unstructured scenes
Authors: Wang Ziyang , Tang Xianxing , Zhou Haibo , Xiao Linjiao , Duan Ji’an 
Published: January 2025

Abstract
This paper proposes a 3D Light Detection and Ranging (LiDAR) simultaneous localization and mapping system for indoor unstructured scenes to improve the robustness and accuracy of automated guided vehicles. First, in the point cloud preprocessing stage, a curve voxel clustering method considering rarity point clouds is proposed, which effectively distinguishes adjacent objects while handling outliers, and achieves accurate clustering of rarity point clouds. Next, in the feature extraction stage, a curvature evaluation method based on principal component analysis is used to ensure the quality of feature extraction through the invariance of viewpoint and distance. Finally, a two-stage degeneration compensation strategy based on a recursive noise estimation adaptive Kalman filter is proposed, which significantly improves pose estimation accuracy by integrating LiDAR and an inertial measurement unit. Experimental results show that the proposed method achieves outstanding performance on the KITTI dataset, with average relative translation error and rotation error RMSE maintained at 0.7922% and 0.7513 deg/100 m, respectively. Additionally, the method achieves over 40% accuracy improvement in real indoor environments compared to LeGO-LOAM.
Primordial perturbations in Type III hilltop inflation models
Authors: Lin Chia-Min , Nalla Harish Dhananjay , Yeh Chen-Pin , Lee Da-Shin 
Published: January 2025

Abstract
We analytically compute the power spectrum of primordial curvature perturbations in Type III hilltop inflation models under the slow-roll approximation. The model parameters are constrained using current Cosmic Microwave Background (CMB) data. The curvature perturbations that exit the horizon at small scales show sufficiently large amplitudes to produce primordial black holes (PBHs). We then consider the quantum one-loop corrections in these models from both the self-interaction of the inflaton and its interaction with the waterfall field. We show the loop corrections in both cases for 60 e-folds of inflation are negligible, ensuring the tree-level results are reliable within the chosen parameter regime.
Toward a test of Gaussianity of a gravitational wave background
Authors: Bernardo Reginald Christian , Appleby Stephen , Ng Kin-Wang 
Published: January 2025

Abstract
The degree of Gaussianity of a field offers insights into its cosmological nature, and its
statistical properties serve as indicators of its Gaussianity. In this work, we examine the
signatures of Gaussianity in a gravitational wave background (GWB) by analyzing the cumulants of
the one- and two-point functions of the relevant observable, using pulsar timing array (PTA)
simulations as a proof-of-principle. This appeals to the ongoing debate about the source of the
spatially-correlated common-spectrum process observed in PTAs, which is likely associated with a
nanohertz stochastic GWB. We investigate the distribution of the sample statistics of the
one-point function in the presence of a Gaussian GWB. Our results indicate that, within PTAs,
one-point statistics are impractical for constraining the Gaussianity of the nanohertz GWB due to
dominant pulsar noises. However, our analysis of two-point statistics shows promise, suggesting
that it may be possible to constrain the Gaussianity of the nanohertz GWB using PTA data. We also
emphasize that the Gaussian signatures identified in the one- and two-point functions in this work
are expected to be applicable to any gravitational wave background.
Pressure-Promoted Ligand to Metal Energy Transfer for Emission Enhancement of [Tb2(BDC)3(DMF)2(H2O)2]n Metal-Organic Framework

Published: January 2025

Abstract
Lanthanide metal-organic frameworks (Ln-MOFs) have received extensive attention in the development of photoluminescent (PL) materials due to their stable structures and unique line-like emission spectroscopic properties. However, in order to prepare Ln-MOFs with high PL quantum yield (PLQY), further improving the sensitization efficiency of the “antenna effect” is essential. Herein, remarkably enhanced PL in [Tb2(BDC)3(DMF)2(H2O)2]n MOF is successfully achieved via high-pressure engineering at room temperature. Notably, the PL intensity continues to increase with the pressure increases, reaching its peak at 12.0 GPa, which is 4.4 times compared to the initial state. Detailed experimental and theoretical calculations have demonstrated that pressure engineering significantly narrows the bandgap of [Tb2(BDC)3(DMF)2(H2O)2]n, optimizing both singlet and triplet energy levels. Ultimately, higher “antenna effect” sensitization efficiency is achieved by promoting intersystem crossing and energy transfer processes. Our work provides a promising strategy for the development of high PLQY Ln-MOFs.

Abstract
Photonic crystal (PhD) waveguides on the silicon nitride (Si

) platform currently are only capable of transmitting a single light polarization, severely limiting polarization diversity applications. In this work, we propose a scheme that combines a single-polarization photonic band gap (SPBG) formed by the first two bands with the same polarization, along with large birefringence between the first two bands with different polarizations. In simple terms, one polarization in the PhC slab waveguide is guided by the SPBG, while the other polarization is index guided, and overlap between the frequency bands for the two polarizations in which propagation is forbidden, dubbed the no-polarization-mode region (NMR), tuned by the aspect ratio of PhC slabs. This approach theoretically achieves PhC waveguides on asymmetric Si

slabs that guide both polarizations within the NMR. Three-dimensional (3D) planewave-method calculations show that through simple adjustment of the aspect ratio of the PhC slab, the first two bands with different polarizations can be adjusted to be shifted in frequency to form the NMR, where neither TE- nor TM-like modes can propagate along the in-plane directions. The NMR is then systematically investigated and optimized for various refractive indices and slab thicknesses, and using the optimized-NMR design, line-defect waveguides supporting propagation of both polarizations are theoretically demonstrated. A 3D finite-difference time-domain simulation shows that an all-polarization (AP) bandwidth as large as 180 nm can be obtained in an optimized PhC waveguide with Si

refractive index of 2.4, which can be tuned by x and y. In addition, our investigation shows that an NMR can also be obtained in an asymmetric rod-type PhC slab even when the refractive index is as low as 1.8, offering significant flexibility in engineering of the structure and refractive index of AP devices on Si

and, by extension, in other moderate-index platforms.
Ag@AgCl nanocomposites: green synthesis using Ixora Coccinea leaf extract and applicability as photocatalyst

Published: January 2025

Abstract
Ag@AgCl nanocomposites were synthesized via green and facile method using silver nitrate (AgNO3) and Ixora Coccinea leaf extract as precursors without using any other agent or chemical. The phytochemicals present in the Ixora Coccinea leaf extract were used as a reducing agent and the Cl− ion source. The effect of the AgNO3 concentration on nanocomposites’ crystallinity, average grain size, and the ratio between Ag and AgCl in nanocomposites was evaluated through UV–Vis spectroscopy, x-ray diffraction, and transmission electron microscopy. The results imply that with an AgNO3 concentration of 0.04 M, Ag@AgCl nanocomposite shows the highest crystallinity and most balance ratio between Ag and AgCl. The photocatalytic activity of Ag@AgCl nanocomposite prepared with 0.04-M AgNO3 solution was investigated against organic dyes (Rhodamine B, Methylene Blue, Congo Red) and textile dyeing wastewater. The photocatalytic results show that, with 20 mg of Ag@AgCl nanocomposite, the Rhodamine B degradation efficiency reaches the highest value of 99.62% after about one hour under visible light irradiation. The Rhodamine B photo-degradation kinetic of Ag@AgCl nanocomposite is well described by the pseudo-first-order kinetic model. Ag@AgCl nanocomposite also shows high photodegradation efficiency with Methylene Blue, Congo Red dyes, and textile dyeing wastewater. These results imply that green-synthesized Ag@AgCl using Ixora Coccinea leaf extract is a promising candidate for photocatalytic applications.

Published: January 2025

Abstract
This work presents the design, implementation, and characterization of a piezoresistive force sensor integrated into a flexible printed circuit board (FlexPCB). We propose a flexPCB-based MEMS sensing system with graphite as the sensing element and polyimide as the principal substrate material, intended for disposable and low-cost applications. The sensor, which was manufactured using a conventional PCB technique and silk-screen printing, can detect biomolecules attached to nanomagnetic particles with an apparent weight of 0.209 V/V · mg−1 when exposed to an applied magnetic field. Within a detection range of 0–80 µg, the sensor delivers a resolution of 10 µg and a limit of detection of 21.16 µg. While the detection limit reflects the weight of the nanomagnetic particle, the actual sensitivity to the biomolecule is substantially higher, allowing the system to detect lower biomolecule quantities effectively.
Role of agro waste in geopolymer concrete: strength, durability and microstructural properties
Authors: Tipraj B , Athira K , Shanmuga Priya T 
Published: January 2025

Abstract
The reduction of the carbon footprint and the preservation of natural raw materials in the construction industry is crucial for the improvement of the environment. Geopolymer is a novel approach that has recently come to the limelight for sustainable and greener construction development due to its lower greenhouse gas emissions. This study focuses on utilizing industrial waste products like Ground granulated blast furnace slag (GGBS), Sugarcane bagasse ash (SBA), and Micronized biomass silica (MBS) for the production of geopolymer concrete. The geopolymer concrete’s performance is assessed by testing various combinations of materials at different percentages to measure compressive and flexural strength, water absorption, water sorptivity, Rapid Chloride ion Penetration test (RCPT), carbonation, resistance to acid attack, and characteristics studies. The results revealed that the combination of 10% of SBA and 8% of MBS on GGBS-based geopolymer improves strength and durability compared to the control mix. The role of MBS has been highlighted, which serves its purpose by densifying the matrix by extending C-S-H gel formation and filling voids caused by incorporating SBA, which is validated through characterization studies—feasibility of agro waste in the geopolymer production.
Comparing indoor and outdoor temperature and air pollution at an urban cooling center: a multiyear case study
Authors: Mendoza Daniel L , Crosman Erik T , Anderson Corbin , Chaudhari Mamta , Gonzales Shawn A 
Published: January 2025

Abstract
Anthropogenic climate change and urbanization have resulted in increasing needs to provide public health protection from the hazards of elevated PM2.5, elevated ozone and extreme heat (or cold) to the public. This is a particularly urgent issue for sensitive groups that are most subject to these hazards, such as the elderly, children, health compromised, and homeless populations. In this study, we compare the indoor versus outdoor temperature and air pollution levels between 17 May 2022 and 31 October 2023 in Salt Lake City, Utah at an older (Northwest Recreation Center) and newer building (Northwest Community Center). Differences between indoor and outdoor ozone were pronounced, with mean indoor ozone being generally ∼40% of outdoor values. Indoor PM2.5 concentrations compared to outdoor value show seasonal variability and were up to 200% higher during wildfires compared to indoor concentration during wintertime inversion events. We found that the older building was less protective against ozone and wildfire PM2.5 pollution than the newer building. Future research could focus on characterizing and quantifying the impact of building age, insulation, and mechanical ventilation on indoor pollutant migration and separate these factors from human activity.
Epilogue
Authors: Scheffler Samuel 
Published: January 2025

Abstract
The influence on our lives of contingent events and circumstances has often been seen as posing a threat of some kind to our agency or our self-understanding. The epilogue considers two versions of the threat. Both are themes in the work of Thomas Nagel. The first, more familiar version is about our lack of control, which may seem to jeopardize our happiness, freedom, or moral subjecthood. The second is about our particularity: our identities are to a great extent defined by the specific circumstances of our existence, and this can seem incongruous with the character of our reflective dispositions and capacities. It is argued that from the perspective of the attachment-sensitive conception developed in this book, the first version poses only a limited threat, while the second does not register as a threat at all.
Drought drives selection for earlier flowering, while pollinators drive selection for larger flowers in annual Brassica rapa
Authors: Rathnayake Kaushalya , Parachnowitsch Amy L 
Published: January 2025

Abstract
Drought-induced changes in floral traits can disrupt plant–pollinator interactions, influencing pollination and reproductive success. These phenotypic changes likely also affect natural selection on floral traits, yet phenotypic selection studies manipulating drought remain rare. We studied how drought impacts selection to understand the potential evolutionary consequences of drought on floral traits. We used a factorial experiment with potted plants to manipulate both water availability (well-watered and drought) and pollination (open and supplemented). We examined the treatment effects on traits of Brassica rapa and estimated phenotypic selection and whether it was pollinator-mediated in these two abiotic conditions. Drought affected plant phenotypes, leading to plants with fewer flowers and ultimately lower seed production. Flowering time did not show variation with watering, but we found the strongest effect of drought on selection was for flowering time. There was a selection for flowering faster in drought but not well-watered conditions. Pollinators instead were the agents responsible for selection on flower size, but we did not find strong evidence that drought effected pollinator-mediated selection. There was a stronger selection for larger flowers in drought compared to well-watered plants, and it could be attributed to pollinators however, there was no significant difference between watering treatments. Our results show the effects of drought are not limited to phenotypic responses and may alter evolution in plants by changing phenotypic selection on traits. The connection between phenotypic plasticity and selection may be important to understand as we found the most variable trait (display size) was not under selection while the trait with different selection in drought (flowering time) did not change in response to drought. Our study highlights the importance of manipulating potential agents of selection, especially to understand fully the potential impacts of components of climate change such as drought.
Unravelling the Efficacy of Internal Quilting Sutures vs Doxycycline Instillations in Preventing Seroma Formation After Gynecomastia Surgery

Published: January 2025

Abstract

Background
Seroma frequently presents as a challenge, following gynecomastia correction surgery. This calls for percutaneous aspiration of accumulated fluid, from the iatrogenic dead space. The authors utilized internal quilting sutures and doxycycline instillation to analyze and compare their roles in seroma prevention.

Objectives
To compare the efficacy of intraoperative internal quilting sutures and doxycycline instillation, in preventing seroma formation and recurrence after gynecomastia surgery.

Methods
After local review board and ethics committee approval, the authors conducted this prospective single-center study of 120 gynecomastia patients with Rohrich's Grades I, II, and III, who underwent surgery between October 2023 and March 2024. Those belonging to Rohrich's Grade IV were excluded. Before surgery, the patients were divided into 3 cohorts of 40 individuals using a computerized randomization protocol. Cohort 1 underwent doxycycline instillation, Cohort 2 underwent internal quilting sutures, and no intervention was carried out in Cohort 3. Seroma diagnosis was confirmed clinically and the data were analyzed. All the patients were followed up for a month.

Results
The incidence of seroma formation, volume of seroma fluid removed, and the number of visits for seroma care were statistically found to be the least in the quilting group compared with the doxycycline and control groups. Univariate logistic regression analysis revealed that patients belonging to both doxycycline and control groups showed significantly higher risk for seroma formation with an odds ratio of 4.705 and 6.524, respectively.

Conclusions
Doxycycline instillation was less effective than internal quilting sutures in preventing seroma formation. Internal quilting sutures are a safe effective, and undemanding adjuvant technique to reduce the rate of formation and recurrence of seroma, after gynecomastia surgery.

Quantification of variegated Drosophila ommatidia with high-resolution image analysis and machine learning
Authors: Hill Hunter J , Sullivan William , Cooper Brandon S 
Published: January 2025

Abstract
A longstanding challenge in biology is accurately analyzing images acquired using microscopy. Recently, machine learning (ML) approaches have facilitated detailed quantification of images that were refractile to traditional computation methods. Here, we detail a method for measuring pigments in the complex-mosaic adult Drosophila eye using high-resolution photographs and the pixel classifier ilastik [1]. We compare our results to analyses focused on pigment biochemistry and subjective interpretation, demonstrating general overlap, while highlighting the inverse relationship between accuracy and high-throughput capability of each approach. Notably, no coding experience is necessary for image analysis and pigment quantification. When considering time, resolution, and accuracy, our view is that ML-based image analysis is the preferred method.
