Penanganan limbah di Indonesia masih menjadi permasalahan yang serius. Penanganan sampah ini masih belum merata di tiap daerah, sallah satunya di Desa Buntu Karau, Kecamatan Juai, Kabupaten Balangan, Kalimantan Selatan. Belum adanya sistem pengelolaan dan kurangnya kesadaran warga desa Buntu Karau akan sampah menjadi salah satu permasalahan penting yang ditemui pada desa tersebut. Menurut kepala Dinas Lingkungan Hidup Kabupaten Balangan total sampah yang dihasilkan Balangan per harinya mencapai 85 ton. Dari total tersebut hanya 22 ton sampah yang terangkut ke TPA dan sisanya terbuang ke sungai atau di sekitar lingkungan rumah warga. Oleh karena itu, tim mahasiswa KKN (Kuliah Kerja Nyata) Waja Sampai Kaputing (Wasaka) ULM melaksanakan program kerja eco enzyme sebagai upaya menangani permasalahan sampah organik tersebut. Pembuatan eco enzyme dirasa sesuai karena dapat diolah menjadi pupuk cair yang dapat bermanfaat bagi warga yang mayoritasnya petani. Metode yang digunakan dalam pengabdian ini adalah sosialisasi sekaligus pelatihan membuat eco enzyme. Limbah organik yang digunakan dalam pembuatan ini terdiri dari sisa buah-buahan serta waluh. Penggunaan waluh dipilih karena Desa Buntu Karau memiliki usaha desa yaitu kerupuk waluh, sehingga ada banyak limbah waluh yang terbuang dalam prosesnya. Kegiatan ini dilaksanakan pada 28 April 2024 dan dihadiri 46 warga.  Sosialisasi ini dibuka dengan demonstrasi pembuatan eco enzyme secara langsung, dan ditutup dengan tanya jawab. Hasil pembuatan eco enzyme dari pelatihan ini diserahkan langsung kepada warga Desa Buntu Karau.Kata kunci: Eco enzyme; sampah organik; pengelolaan sampah, pupuk organik

The learning process on Hormone in Human Reproduction material of XI class of senior high school has employed Merdeka Curriculum. After the content of the Merdeka Curriculum book was analyzed, it was determined that the practicum activities were limited to hormones in the menstrual cycle and did not meet the requirements of phase F learning achievement. During practicum activities at school, teachers exclusively employ textbooks. The practicum guidelines in textbooks have not been able to comprehensively guide the students to complete the practicum activities, resulting in a lack of comprehension. The objective of this research was to generate a practicum guide that was valid, feasible, convenient, and effective. This research was a development study that employs the Plomp model (preliminary stage, prototype stage, and assessment stage). The validity test was assessed by three lecturers. The feasibility test was administered to three students with varying abilities (High, Moderate, Low), and six students were randomly selected. The practical guide convenience test was administered to one teacher and 45 students. The data was processed using a modified percentage formula from Ridwan (2013). The validity value was 88.68% (very valid), the feasibility test for three students was 96.11% (very feasible), and the feasibility of six students was 89.58% (very feasible). The convenience test administered by the teacher yielded results of 98.5% (very easy) and 84.34% students (very easy). The effectiveness for skill test yielded results of 81.14% (very effective) and the effectiveness for attitude yielded 91% (very effective), which were processed using the modified percentage formula from Sudijono (2006). Thus, the practicum guide developed for hormone material in human reproduction of XI class of senior high school is valid, feasible, convenient, and effective in the use of the learning process.

Fluid Dynamics Duality and Solution of Decaying Turbulence
Authors: Migdal Alexander
Published: December 2024

We present a duality in the dynamics of incompressible Navier-Stokes fluids in three dimensions, leading to a reformulation of the problem as a one-dimensional momentum loop equation. Importantly, the momentum loop equation does not admit finite-time blow-up solutions. The phenomenon of decaying turbulence emerges as a solution to this equation and can be interpreted as a string theory with a discrete target space composed of regular star polygons and Ising degrees of freedom along their edges. This string theory is solvable in the turbulent limit, which corresponds to a quasiclassical approximation in a nontrivial, calculable background. As a result, the spectrum of decay exponents is derived analytically and exhibits excellent agreement with both experimental data and numerical simulations. Notably, the spectrum includes complex conjugate pairs of exponents associated with the nontrivial zeros of the Riemann zeta function. The classical Kolmogorov scaling laws are replaced by specific functions derived from number theory, exhibiting nonlinear behavior in log-log scale. In particular, we compare the theoretically predicted effective exponent for the second moment of the velocity difference with new DNS results. This comparison reveals a remarkable agreement, with deviations well within the small DNS error margin over a broad range of the scaling variable r / sqrt(t).
The Generalized Characteristic Polynomial of the Km,n-Complement of a Bipartite Graph
Authors: Zhao Weiliang , Gong Helin
Published: December 2024

The generalized matrix of a graph G is defined as M(G) = A(G) − tD(G) (t ∈ R, A(G) and D(G) respectively denote the adjacency matrix and the degree matrix of G), and the generalized characteristic polynomial of G is merely the characteristic polynomial of M(G). Let Km,n be the complete bipartite graph. Then the Km,n-complement of a subgraph G in Km,n is defined as the graph obtained by removing all edges of an isomorphic copy of G from Km,n. In this paper, by using a determinant expansion on the sum of two matrices (one of which is a diagonal matrix), a general method for computing the generalized characteristic polynomial of the Km,n-complement of a bipartite subgraph G was provided. Furthermore, when G is a graph with rank no more than 4, the explicit formula for the generalized characteristic polynomial of the Km,n-complements of G is given.

Towards the Application of a Dynamic BIM-aided Waste Management System in Enabling Net-zero Cities: A State-of-art Review
Authors: Olubambi Ademilade , Aigbavboa Clinton , Ikotun Bolanle
Published: December 2024

Greener construction can be possible in any construction industry when net-zero waste is achieved via sustainable practices. This study employs a state-of-art review to examine the potential of utilizing a dynamic BIM-aided waste management system in reducing/or eliminating waste throughout the construction life cycle, supply chain, and construction and demolition actions towards realizing net-zero cities. This study outlines the connection and applications of BIM-aided systems in construction and demolition waste management. The aim is to create a dynamic, life cycle BIM-aided waste management system that can effectively manage waste and advance net-zero construction. Throughout the construction life cycle, all relevant operations of the BIM-aided waste management system were indicated. Results from the planning phase show that BIM may be utilized to generate an effective schedule for material ordering, fabrication, and delivery of all building components. During the design phase, all modifications made to the building model are automatically updated. The 3D geometry can be used for project sequencing, take-offs, and integrated energy analysis throughout the procurement phase. Virtual construction modeling, which is particularly cost-effective, can be utilized during the construction phase, while BIM technology can be employed in the operation phase for maintenance scheduling, building system analysis, asset management, tracking and/or space management, and disaster planning. In conclusion, this study highlights the growing knowledge and utilization of BIM-aided waste management systems in construction, as well as how waste may be reduced to zero and then prevented by using a BIM-aided waste management system. As a result, utilizing the benefits invested in the process and design of a BIM-aided system should be need-based and in line with the general requirement for sustainability in any country's construction industry, since utilizing when there is no need is not productive overall.
Dynamically Tunable Multifunction Attenuator Based on Graphene Integrated Dual-Mode Microstrip Resonators
Authors: Yang Zhi-Qiang , Wen Quan-Long , Fan Chi , Wu Bian , Qiu Yang
Published: December 2024

In this paper, a design method of tunable multifunctional attenuators is proposed by analyzing the characterization of dual-mode microstrip resonators loaded by graphene sandwiched structure (GSS). Firstly, the odd-even mode method is applied to analyze the resonance characteristics of two common GSS loaded dual-mode resonators, which clearly describe the influence of graphene on these resonators. Then, two kinds of multifunction attenuator with dynamically tunable attenuation are proposed based on graphene integrated dual-mode resonators, which enables controllable characteristics and multi-frequency transmission options for traditional attenuating devices. Finally, all the proposed multifunctional attenuators are fabricated and measured. The experimental results are in good agreement with the simulation results, which further verifies the conclusions and design method proposed in this paper.
Quality Comparison of Dynamic Auditory Virtual Reality (VR) Simulation Approaches of Approaching Vehicles Regarding Perceptual Behavior and Psychoacoustic Values
Authors: Krautwurm Jonas , Oberfeld-Twistel Daniel , Huisman Thirsa , Altinsoy M. Ercan , Maravich Maria Mareen
Published: December 2024

Traffic safety experiments are often conducted in virtual environments in order to avoid dangerous situations and conduct them more cost-efficiently. This means that attention must be paid to the fidelity of the traffic scenario reproduction, because the pedestrians’ judgments have to be close to reality. To understand the behavior in prevailing audio rendering systems better, a listening test was conducted, which focused on perceptual differences between simulation and playback methods. Six vehicle driving-by-scenes were presented using two different simulation methods, three different playback methods, and in additional binaural recordings from the test track acquired during the recordings of the vehicle sound sources for the simulation. Each vehicle driving-by-scene was characterized by different vehicle types and different speeds. Participants rated six attributes of the perceptual dimensions “timbral balance”, “naturalness”, “room-related”, “source localization", “loudness” and “speed perception”. While the ratings showed a high degree of similarity of the ratings of the sound attributes in the different reproduction systems, there were minor differences in the speed and loudness estimations and the different brightness perceptions stood out. A comparison of the loudness ratings in the scenes featuring electric and combustion engine vehicles highlights the issue of reduced detection abilities with regard to the former.
Identification of Decentralised Control Systems
Authors: Karabutov Nikolay
Published: December 2024

The identification problem of decentralised control systems (DS) is considered. Analysis shows that this problem has not been given sufficient attention. The complexity of systems and a priori uncertainty require the development of approaches and methods. DS parametric identifiability (PI) requires a solution. We propose the approach to the PI assessment based on the fulfilment of the constant excitation condition and consider relationships in the subsystems. PI conditions are got and algorithms for parametric and signal adaptive identification are received. We consider DS with non-linearities satisfying the quadratic condition. The exponential dissipativity of the identification system is proved using Lyapunov vector functions. The influence of interrelations considers on properties of parameter estimates. Examples are given. A method is proposed for the construction of adaptive algorithms under functional constraints.
The Significance of Renal Impairment in Children with Eating Disorders
Authors: Hamilton Avisha Meleika , Eisenhut Michael
Published: December 2024

Background: Eating disorders have previously been associated with renal impairment. Low muscle mass reduces serum creatinine used for calculation of the estimated glomerular filtration rate (eGFR) leading to overestimation of renal function.
The objectives of our study were:
• To investigate the percentage drop in creatinine (pdCr) during rehydration as a new indicator of renal dysfunction not dependent on muscle mass.
• To investigate a correlation of cardiovascular function and fluid management with renal function.
Methods: In a 5-year retrospective cohort study of all consecutive children admitted because of an eating disorder renal function expressed as eGFR on admission and as pdCr between admission and the lowest creatinine was analysed in relationship to cardiovascular parameters and fluid management.
Results: We included 29 patients. Mean age was 13.4 years. A pdCr after admission was noted in 26/29 (89.7%). The eGFR was 90 in 13/15 (86.6%). In patients with a fluid management plan the pdCr had a median of 18.6% and without of 6.4% (p=0.02). Renal dysfunction was not related to cardiovascular parameters.
Conclusions: The majority of patients with an eating disorder had renal impairment. PdCr was more sensitive in detection of renal impairment compared to eGFR.

Authors: Aragonés Raúl , Oliver Joan , Ferrer Carles
Published: December 2024

Heat-intensive industries (e.g., iron & steel, aluminum, cement) and explosive sectors (e.g., oil & gas, chemical, petrochemical) face challenges in achieving Industry 4.0 goals due to the widespread adoption of industrial Internet of Things (IIoT) technologies. Wireless solutions are favoured in large facilities to reduce the costs and complexities of extensive wiring. However, conventional wireless devices powered by lithium batteries have limitations, including reduced lifespan in high-temperature environments and incompatibility with explosive atmospheres, leading to high maintenance costs.
Fluorescence-Guided Resection of GL261 Red-FLuc and TRP-McHerry-FLuc Mouse Glioblastoma Tumors
Authors: Rodgers Louis T , Maloney Bryan J , Hartz Anika MS , Bauer Björn
Published: December 2024

Most preclinical studies on glioblastoma (GBM) fail to provide translational utility in the clinic. Fluorescence-guided surgery using 5-aminolevulinic acid (5-ALA) improves tumor resection, disease prognosis, and thus, patient outcomes. Given the critical role of surgery in managing recurrent GBM, it is essential to incorporate surgical elements into preclinical models to accurately reflect clinical scenarios and enhance translational success. However, existing protocols for 5-ALA-guided resection in preclinical models are limited and often lack clinical relevance. To address this gap, we developed a novel protocol for the 5-ALA-guided resection in two mouse GBM models: TRP-mCherry-FLuc and GL261 Red-FLuc. Resection of TRP-mCherry-FLuc tumors significantly extended survival and mitigated weight loss compared to controls. Similarly, GL261 Red-FLuc tumor resection increased survival, reduced weight loss, and slowed tumor progression. This study presents a clinically relevant protocol for 5-ALA-guided resection in preclinical GBM models, providing a platform for future research to integrate adjuvant therapies and enhance their potential translation into clinical practice.
The Rosencrantz Coin: Predictability and Structure in Non-Ergodic Dynamics. From Recurrence Times to Temporal Horizons
Authors: Volchenkov Dimitri
Published: December 2024

We examine the Rosencrantz coin that can "stick" in states for extended periods. Non-ergodic dynamics is highlighted by logarithmically growing block lengths in sequences. Traditional entropy decomposition into predictable and unpredictable components fails due to the absence of stationary distributions. Instead, sequence structure is characterized by block probabilities and Stirling numbers of the second kind, peaking at block size n/logn. For large n, combinatorial growth dominates probability decay, creating a deterministic-like structure. This approach shifts the focus from predicting states to predicting temporal horizons, providing insights into systems beyond traditional equilibrium frameworks.

Published: December 2024

Attention Bias Modification (ABM) is a cost-effective emotional intervention that has the potential to be used in daily settings beyond clinical environments. However, its interactivity and user engagement are known to be limited and underexplored. Here, we propose Uplifting Moods, a novel mood intervention app that combines gamified ABM and augmented reality (AR) to address the limitation associated with the repetitive nature of ABM. By harnessing the benefits of mobile AR’s low-cost, portable and accessible characteristics, this approach is to help users easily take part in ABM, positively shifting one’s emotion. Throughout quantitative and qualitative data analysis in a study with 24 participants, we report that the approach uniquely adds fun, exploring, and challenging features helping improve engagement and moods. It also highlights the importance of personalisation and consideration of gaming style, music preference and socialisation in designing a daily AR ABM game as an effective mental wellbeing intervention.
First Look at Safety and Performance Evaluation of Commercial Sodium-ion Batteries

Published: December 2024

Herein we investigate the performance and safety of four of the early-stage, commercial Na-ion batteries available in 2024, representing the most popular cathode types across research and commercialization: polyanion (Na-VPF), layered metal oxide (Na-NMF), and Prussian blue analog (Na-tmCN). The cells deliver a wide range of energy density with the Na-tmCN delivering the least (23 Wh/kg) and Na-NMF delivering the most (127 Wh/kg). Capacity retention under specified cycling conditions and with periodic 0V excursions was the most robust for the Na-tmCN cells in both cases. Accelerating rate calorimetry (ARC) and nail penetration testing finds that Na-NMF cells do undergo thermal runaway in response to abuse, while the Na-VPF and Na-tmCN exhibit only low self-heating rates (<1 °C/min). During these safety tests, all cells exhibited off-gassing, so we conducted in-line FTIR equipped with a heated gas cell to detect CO, CO2, CH4, toxic acid gases (HCN, HF, NH3), and typical electrolyte components (carbonate ester solvents). Gases similar to those detected during Li-ion failures were found in addition to HCN for the Na-tmCN cell. Our work compares different types of commercial Na-ion batteries for the first time allowing for a more wholistic comparison of the safety and performance tradeoffs for different Na-ion cathode types emerging in 2024.

Published: December 2024

This study examines how different filming techniques can enhance the quality of 3D reconstructions with a particular focus on their use in indoor crime scene investigations. Using Neural Radiance Fields (NeRF) and Gaussian Splatting we explored how factors like camera orientation, filming speed, data layering, and scanning path affect the detail and clarity of 3D reconstructions. Through experiments in a mock crime scene apartment, we identified optimal filming methods that reduce noise and artifacts, delivering clearer and more accurate reconstructions. Filming in landscape mode, at a slower speed, with at least three layers and focused on key objects produced the most effective results. These insights provide valuable guidelines for professionals in forensics, architecture, and cultural heritage preservation, helping them capture realistic high-quality 3D representations. The study also highlights the potential for future research to expand on these findings by exploring other algorithms, camera parameters, and real-time adjustment techniques.

Published: December 2024

Climate change, exacerbated by global warming in recent decades, has had a devastating impact on agriculture, leading to a significant decline in productivity in some areas. In some regions, the extreme effects have resulted in the complete destruction of crops, threatening food security and the balance of ecosystems, while in others production has fallen to alarming levels. The automation of irrigation, together with the generation of climate reports based on artificial intelligence, contributes to the optimization of resources by reducing excessive water and energy consumption, supporting plant health through proper irrigation and increasing sustainable agricultural productivity by providing suggestions and statistics to streamline the agricultural process. In this paper, the authors present a system that allows real-time monitoring of parameters such as temperature and humidity, providing detailed information and advanced analytics for each device and area monitored using AI (Artificial Intelligence). This uses data from all the devices that are integrated into the application to assess the state of the climate at a national level. The integration of artificial intelligence in the context of monitoring and irrigation of agricultural areas is a step forward in the development of sustainable agriculture and for the adaptation of agriculture to increasingly aggressive climate phenomena.

Published: December 2024

Background: Early diagnosis of cholangiocarcinoma (CCA) is still unreliable, resulting in poor patient outcomes. Volatile organic compounds (VOCs), emitted by the body, could help detect disease-related metabolic changes, aiding diagnosis. Objective： This study aims to assess if Gas chromatography ion mobility spectroscopy (GC-IMS) detection of serum VOCs can differentiate CCA from benign biliary diseases (BBD) and evaluate its diagnostic effectiveness. Method：Serum samples from 46 CCA and 46 BBD patients were collected. GC-IMS detected VOCs in the serum groups, and PCA was performed to analyze group differences. Utilize the Receiver Operating Characteristic (ROC) curve to assess the diagnostic efficacy of VOCs in CCA and analyze the correlation between VOCs and pathological characteristics. Resuit: Using GC-IMS, we detected 27 VOCs in two serum samples, including 23 known and 4 unknown. A PCA 3D scatter plot highlights distinct VOC patterns and clustering for CCA patients versus BBD. Statistical analysis reveals significant differences in 14 substances between the BBD and CCA groups, with 8 VOCs exhibiting upregulation and 6 demonstrating downregulation in the CCA group. ROC analysis reveals that (E) -2-nonenal exhibits the highest diagnostic efficiency for CCA, with an AUC value of 0.761 (95%CI: 0.662 - 0.860). Conclusion: Serum VOC analysis could aid the diagnosis and surveillance of CCA.

This study looks into the impact of public health emergencies on young people's interest and awareness of e-health. A questionnaire assessing e-health literacy was administered to 300 university students in China, and the data was analysed by employing SPSS 25.0. The data show that the COVID-19 pandemic increased students' interest in e-health and assisted to boost literacy levels. Nevertheless, there are still gaps, particularly in their capacity to find and successfully use credible internet health information. Addressing privacy and security problems with e-health tools, as well as creating targeted health education initiatives, are key steps towards bridging these gaps. These measures will enable students to better interpret and apply health information, boosting their self-management abilities and general confidence in controlling their own health.
Influence of Operating Parameters on the Efficiency of a Multi-Components Flash Distillation Operation
Authors: Bendjaouhdou Chaouki
Published: December 2024

This research aims to study by numerical simulation the influence of various parameters on the efficiency of a flash distillation. The main characteristic of this system is that it feed a binary or a multi-components distillation column, such as a debutaniser column, by providing this last one by both a liquid and a gas stream. The study of the flash distillation is carried out in order to emphasis the influence of operating parameters on the gas vaporized fraction (δ). The studied parameters are: temperature and pressure inside the flash tank, feed flow rate, and the feed composition. The obtained results showed that for an ideal mixture, the vaporized fraction is sensitive to the pressure, temperature and feed composition and is non- sensitive to the feed flowrate.

Published: December 2024

We introduce ShapeBand, a new shape-changing wristband designed for exploring multisensory and interactive anxiety regulation with soft materials and physiological sensing. Our approach takes a core principle of self-help psychotherapeutic intervention, aiming to help users to recognize anxiety triggers and engage in regulation with attentional distraction. We conducted user-centered design activities to iteratively refine our design requirements and delve into users’ rich experiences, preferences and feelings. With ShapeBand, we explored bidirectional and dynamic interaction flow in anxiety regulation and subjective factors influencing its use. Our findings suggest that integrating both active and passive modulations can significantly enhance user engagement for effective anxiety intervention. This study provides valuable insights into the future design of tangible anxiety-regulation interfaces that can be tailored to subjective feelings and individual needs.
