The Comparison of Compression and Conversion Performance for Real-time Volumetric Video Streaming by Using Dynamic Point Cloud and Mesh Coding
Authors: Choi Yihyun , Ryu Eun-Seok 
Published: July 2024

Abstract

In volumetric video content, dynamic 3D objects containing frame information, akin to a video, are utilized to depict the movement of 3D objects. Due to their larger data size compared to static 3D objects, efficient compression techniques are imperative for dynamic 3D objects. Consequently, the moving picture experts group (MPEG) has undertaken research on video-based dynamic mesh coding (V-DMC) for compressing dynamic mesh, and video-based point cloud compression (V-PCC) for compressing dynamic point cloud. Moreover, mesh and point cloud serve as data structures representing 3D object in virtual reality, each with distinct advantages and disadvantages. Hence, advancements in volumetric video can be anticipated through the conversion of dynamic point cloud obtained from real world into dynamic meshes, which offer rendering advantages. Enabling real-time streaming of volumetric video using dynamic mesh necessitates not only the conversion between dynamic point cloud and dynamic mesh but also efficient compression techniques tailored for dynamic point cloud or dynamic mesh. This paper conducts experiments involving conversion and compression from dynamic point cloud to dynamic mesh using a poisson surface reconstruction (PSR) based converter and international compression standards for dynamic mesh and dynamic point cloud. Furthermore, subjective performance evaluations are conducted on the experimental results, comparing the dynamic meshes generated using V-DMC and V-PCC.

Published: July 2024

Abstract

Background: Young women living with perinatal infections of the Human Immunodeficiency Virus (YWLPHIV) in low- and middle-income countries are more likely to be challenged by social and health inequities, which can make adherence to life-long treatment difficult. We aimed to learn more about how YWLPHIV in Cape Town negotiated their adherence to antiretroviral treatment (ART) within their material environments.
Methods: We adopted a multisensory arts-based community participatory approach and used visual and digital mediums for data-collection and analytical purposes. We developed an Adherence Assemblage model to guide our study. The co-research team consisted of three academics, seven YWLPHIV (although they approved the study they could not be named as authors to protect their identities), one counsellor and two visual ethnographers.
Results: We co-creatively synthesised our findings into one research documentary and five co-creative artworks. We synthesised four storylines: ‘living with a (un)exposed HIV secret’, ‘multisensory experience of adherence’, ‘things that matter in adherence’, and ‘engaging spaces and places’. Things such as the pill itself were perceived as triggers for associated memories and evoked emotional responses, impacting the adherence behaviours of YWLPHIV. At times, non-adherence was used as an act of control, with young women claiming power by rejecting the pills. Besides the more obvious lines of argument on power dynamics, the findings suggest that materiality influences adherence too. However, it is seldom used as an analytical concept to investigate challenges related to ART.
Conclusions: In conclusion, understanding the material environment's role in adherence is crucial for developing more effective support systems for YWLPHIV. Further research that prioritises the specific needs of YWLPHIV emotional, cognitive, and psychosocial development, while paying attention to the material environment is needed.

Abstract

Spatial proteomics enable detailed analysis of tissue at single cell resolution. However, creating reliable segmentation masks and assigning accurate cell phenotypes to discrete cellular phenotypes can be challenging. We introduce IMmuneCite, a computational framework for comprehensive image pre-processing and single-cell dataset creation, focused on defining complex immune landscapes when using spatial proteomics platforms. We demonstrate that IMmuneCite facilitates the identification of 32 discrete immune cell phenotypes using data from human liver samples while substantially reducing nonbiological cell clusters arising from co-localization of markers for different cell lineages. We established its versatility and ability to accommodate any antibody panel and different species by applying IMmuneCite to data from murine liver tissue. This approach enabled deep characterization of different functional states in each immune compartment, uncovering key features of the immune microenvironment in clinical liver transplantation and murine hepatocellular carcinoma. In conclusion, we demonstrated that IMmuneCite is a user-friendly, integrated computational platform that facilitates investigation of the immune microenvironment across species, while ensuring the creation of an immune focused, spatially resolved single-cell proteomic dataset to provide high fidelity, biologically relevant analyses.

Published: July 2024

Abstract

Tributyl borate (TBB) is among the widely used film-forming electrolyte additives in lithium-ion batteries (LIBs). It possesses the capability to produce an inorganic solid electrolyte interphase with abundant polar boron-containing compounds, functioning as a solid electrolyte interlayer (or cathode electrolyte interlayer), thus effectively isolating the electrode material from the electrolyte and averting parasitic reactions. Herein, the TBB could contribute to the formation of an inorganic solid electrolyte interphase rich in polar B-F and B-O bonds, thus enhancing the stability of the interface between the electrolyte and cathode materials. The findings demonstrate that the inclusion of 0.5 wt% TBB significantly enhances the stability of the electrode/electrolyte interface in Li‖LiMn0.8Fe0.2PO4 batteries. After 600 cycles, the specific capacity reaches 107.9 mAh g− 1 with a capacity retention of 86.45%. This indicates outstanding electrochemical performance and excellent cycling stability. Consequently, TBB exhibits potential as an electrolyte additive for future high-energy density lithium batteries.

Published: July 2024

Abstract

Background and Aims
Salinity significantly impairs wheat (Triticum aestivum L.) growth and yield, posing a major challenge to agriculture. This study investigates the effectiveness of the fungal endophyte Penicillium chrysogenum in mitigating the adverse effects of salinity on wheat growth.
Methods
In this study, the effect of fungal endophyte P. chrysogenum on the improvement of morphophysiological and biochemical traits of wheat plant under salt stress (0, 50, 100 and 150 mM NaCl) was factorially conducted in the form of a completely randomized design with three replications in vitro and greenhouse conditions.
Results
Treatment of wheat seeds with P. chrysogenum resulted in superior germination rates under 150 mM saline stress compare to untreated control. Notably, the endophyte treatment led to enhancements in shoot and root lengths, as well as total fresh and dry weights, with increases of 57.52%, 169.23%, 10.65%, and 76.20%, respectively. The endophytes presence was associated with increased levels of hydrogen peroxide, malondialdehyde, proline, and soluble carbohydrates by 29.34%, 36.17%, 36.13%, and 76.54%, respectively. Enhanced concentrations of phenolic compounds, flavonoids, anthocyanins, and overall antioxidant activity were observed in treated plants, alongside elevated activities of antioxidant enzymes (CAT, POD, PPO, APX). These adaptations contributed to improved stress tolerance and a reduction in reactive oxygen species (ROS).
Conclusion
The results highlight P. chrysogenum as an effective biological agent for enhancing wheat resilience to salinity, offering a promising strategy for improving crop performance in saline areas. Further studies are needed to understand the complex interactions and practical agricultural uses.

Published: July 2024

Abstract

In this study, we present a kinetic-metabolic model describing adeno-associated virus (AAV) production via Hek293 cells, encompassing the main metabolic pathways, namely glycolysis, tricarboxylic acid cycle (TCA), pyruvate fates, the pentose phosphate pathway, anaplerotic reaction, amino acid metabolism, nucleotides synthesis, biomass synthesis and the metabolic pathways of protein synthesis of AAV (capsid and Rep proteins). For the modelling, Michaelis-Menten kinetic is assumed to define the metabolic model. A dataset from bioreactor cultures containing metabolite profiles of adeno-associated virus 6 (AAV6) production via triple transient transfection at low cell density culture, including concentration profiles of glutamine, glutamic acid, glucose, lactate, and ammonium, is utilized for fitting and computing the model parameters. The model resulting from the adjusted parameters well defines the experimental data. Subsequently, a Sobol-based global sensitivity analysis procedure is applied to determine the most sensitive parameters in the final model.

Published: July 2024

Abstract

Quantum Key Distribution (QKD) is a cryptography protocol based on the fundamental principles of quantum physics (QP). Teaching this subject does not require extensive knowledge beyond these principles, making it suitable for inclusion in high school curricula. Despite its relevance, teaching QKD in high schools is yet understudied. In this study, we collected responses from 12th -grade students from various schools that adopted and applied the Discipline-Culture vision of the physics curriculum. We assessed their understanding through conceptual and quantitative problems and examined their attitudes regarding the motivation to study this subject. We analyzed the responses using content analysis, identifying the challenges and affordances of teaching QKD. The challenges faced by students have been categorized into three themes: difficulties with QP, difficulties with the QKD protocol, and difficulties with the mathematics involved in this context. This work enhances educators’ ability to address the challenges of teaching QP and suggests that teaching QKD in high school strengthens students’ motivation to study QP.

Published: July 2024

Abstract

Erosion poses a significant challenge along the river Subansiri in Assam, India impacting river banks and sediment breakdown. This paper presents a comprehensive study on the identification of soil erosion-susceptible areas in the Subansiri Basin using fuzzy logic modeling and sediment transport index (STI) analysis with emphasis on X-Ray Diffraction (XRD) and grain size analysis. The soil erosion map's overall findings showed that the areas it covered were vulnerable to erosion in severe, very high, high, moderate, and low levels. Slope gradients and flow accumulation were used to calculate the STI on the Raster Calculator in ArcGIS. The Sediment Transport Index ranges from 0 to 2770. This study also aims to elucidate the mineral composition and grain size distributions of sediments sourced from the Subansiri river in Assam. Examination of 12 soil samples facilitated the assessment of their mineral composition and size distribution. Sieve analysis unveiled that a predominant 80% of the soil along the Subansiri river constitutes sand, with lesser percentages attributed to silt and clay, following USDA primary classification guidelines. Utilizing XRD methodology, the major crystalline minerals identified in these sands encompassed Quartz, Montmorillonite, Illite, Calcite, and Plagioclase Feldspar Albite. Skewness and kurtosis is also studied to determine the shape and distribution of the soil samples and the values range from 0.25 to 0.70 signifying a fine skewed to very fine skewed and from − 1.16 to -1.93 showing a very platykurtic distribution. Thus, for a thorough investigation of soil erosion, this research provides a novel hybrid methodology that integrates fuzzy logic, STI, XRD and grain size analysis.

Published: July 2024

Abstract

Background: Herbal medicine is well known among the ancient medical sciences. Healing properties have been observed in some species of Daphne. The effect of Daphne plant extract on the K562 cell line has been previously studied, and Gleevec is a well-known and effective drug for the treatment of chronic myelogenous leukemia.
Material and Methods: In this study, the simultaneous effects of using herbal medicine and a targeted therapy drug on the K562 cell line were investigated. The presence of some species of Daphne in Iran motivated us to evaluate the cytotoxic effect of Daphne mucronata on human leukemia cancer cells. The antiproliferative activity of the dichloromethane extract of daphne mucronate (Thymelaeaceae), a new anticancer medicinal plant, was evaluated. Cell viability was quantitated by MTT assay. Apoptotic and necrotic changes in the cell membrane were examined using flow cytometry. Changes in Bax and Bcl2 gene expression were investigated using real-time PCR. The MIC and the IC50 of the crude extract were calculated, and the MIC and IC50 of the combination of the Daphne extract and imatinib were tested in the K-562 cell line.
Results: K-562 cells responded to the extract treatments in a dose-dependent manner, and the increase in the expression of Bcl2 and decrease in the expression of the Bax gene increased with increasing extract concentration. Flow cytometry revealedthat most of the cells underwent apoptosis.
Conclusion: Daphne extract effectively decreased the viability of the cell line. The necrotic effect of the Daphne extract was evaluated, and an increase in the gene expression of Bcl2 was observed in cells exposed to the Daphne extract. The combination of Daphne extracts with imatinib enhances the cytotoxic effect of imatinib.

Published: July 2024

Abstract

Water is essential for human life, agriculture, and the environment. This study examines the physicochemical characteristics and heavy metal levels in the Metti River, located in Dambi Dollo town, Kellem Zone, Ethiopia. Water samples were collected from three sites (upstream, midstream, and downstream) during both dry and rainy seasons. The findings revealed that key parameters were within acceptable limits for drinking and irrigation: temperature (24.8°C – 25.6°C), pH (6.93 – 8.01), electrical conductivity (157.6 μS/cm – 421.3 μS/cm), turbidity (63.8-194.35 NTU), TDS (98.6-146.3 mg/L), DO (8.6-10.2 mg/L), sulfate (39.29-91.64 mg/L), alkalinity (101-120 mg CaCO3/L), nitrate (0.49-1.09 mg/L), nitrite (0.01-0.03 mg/L), chloride (2.83-35.62 mg/L), ammonia (0.95-4.4 mg/L), and phosphate (0.11-0.41 mg/L). However, elevated levels of iron, lead, and manganese may indicate sewage contamination. Despite this, the water quality remains suitable for irrigation and drinking according to WHO/FAO standards. This study underscores the need for continuous monitoring and addressing pollution sources to ensure the river's sustainability for agriculture in the Kellem Wollega Zone.

Published: July 2024

Abstract

The widespread prevalence of Wi-Fi and Bluetooth or its low-power version, Bluetooth low energy (BLE), in modern society has significantly increased their use for setting up wireless connectivity in various Internet-of Things (IoT)-based applications, such as patient monitoring, indoor localization and environment monitoring. The growing demand for integrating efficient power management solutions into these IoT applications has motivated us to focus on the measurement and analysis of power consumption during wireless scan activities using Wi-Fi and BLE since these are crucial for the connection establishment. Although a few research exists on the measurement and analysis of power consumed by wireless technologies like Wi-Fi, BLE and Zigbee in the literature, none have paid attention to the accurate measurement and analysis of real-time power consumption during wireless scan operations at the application level.
To address this gap, we have designed a novel mobile application for the accurate measurement of real-time power consumption during wireless scan operations in order to assess the energy efficiency of various IoT applications involving those wireless technologies. Extensive experimentation was carried out in this study to measure real-time power consumption during Wi-Fi and BLE scans as well as operations without any scans (i.e., no scan) at varying durations and distances of the measuring device from the beacon. Additionally, a comparative statistical analysis of the collected power measurements under three different cases (Wi-Fi scan, BLE scan and no scan) using mean, median and standard deviation was performed to demonstrate the real-time power consumption usage patterns of these operations. This is followed by an insightful discussion on the influence of duration and distance on such power consumption patterns. Furthermore, several avenues for future research based on the findings of this study are also presented here.

Published: July 2024

A method for demanganization of technogenic aqueous solutions is presented. This method involves electrocoagulation purification of aqueous systems from high metal contents and extraction of manganese (II) ions by carbon sorbent adsorption. A coagulation technology based on electrogenerated aluminum hydroxide was used. According to diffraction analysis, such a hydroxide exhibits an amorphous porous hydrogel structure with a developed sorbing surface. The micellar structure of the as-generated aluminum hydroxide, which was attributed to a modification of gibbsite, is represented by the following colloidal particle: {[m Al(OH)3] nAl(OH)2+ (n-x) OH-}x+ xOH-. The associative process of sorption on gibbsite occurs by dispersion interaction, which is governed by the force of electrostatic attraction of instantaneous and induced dipoles of electrically neutral sorbent molecules and the [Mn (OH2)2(OH)2]0 manganese hydroxo-aquo complex. The adsorption limiting value of manganese ions amounted to 4.9 mmol/g at 298 K and pH 5.8, with the adsorption equilibrium constant reaching 1.36 . 104. The electricity consumption corresponded to 12.0 А.h at an optimal electrocoagulation duration of 15 min and a current density of 1.6 мА/сm2. The final purification of aqueous solutions using carbon sorbents was conducted in a slightly alkaline medium at pH 7.5. The manganese sorption value reached 1.68 mmol/g. Therefore, the resource-saving effect of processing of technogenic hydro-mineral solution is manifested in a significant reduction of heavy metal salts and in obtaining of demanded mixed coagulants of aluminum and iron sulfates from water purification wastes. Another positive effect of electrochemical water purification consist in water disinfection and its improved ogranoleptic parameters.
