Published: December 2024

Abstract
Complications have long haunted physicians and patients in clinical medicine. However, the evaluation of complications caused by specific diseases is typically relied on the experience of clinicians or clinical cases. Especially, vast complication diseases involve multiple human body systems, increasing the difficulty of the clinical confirmation. Based on a large scale human disease complication network extracted from the clinical medicine knowledge database, we propose a nonlinear model combined local topological structures and machine learning to explore latent disease-complication relations. As an example, we apply the model to predict unidentified complications of COVID-19 and to detect potential extrapulmonary complications which are significant in the post-pandemic period. Our approach provides an efficient method to identify the candidate complications from the structure of complex network.

Abstract
The advancement of microelectronics technology has led to an increased demand for heat dissipation in devices. In response to this challenge, microchannel heat sinks (MCHS) have been introduced as a viable solution. The heat dissipation capabilities of MCHS can be enhanced by adopting pin fins, which serve to augment the solid–liquid contact area and disrupt the fluid boundary layer. Most research on MCHSs with pin fins has concentrated on vertical pin fin configurations, with a comparatively limited investigation into inclined pin fins. To further enhance the thermal performance of MCHS with pin fins, this study presents a novel MCHS with inclined pin fins (MCHS-IPF). The flow and heat transfer characteristics under steady-state conditions were analyzed using three-dimensional numerical simulations. Additionally, geometric optimization was conducted on the tilt angle (θ: −30° to 30°, excluding 0°) and the secondary flow channel width ratio (β) to achieve improved overall performance. The results show that the MCHS-IPF significantly enhances thermal dissipation capability compared to a conventional MCHS with vertical pin fins (MCHS-VPF). As the tilt angle remains constant, the heat dissipation capacity of MCHS-IPF improves with an increase in β. The MCHS-IPF with β = 0.6 and θ = −30° at Re = 600 shows a notable enhancement of 57.7% in the Nusselt number compared to the MCHS-VPF. This MCHS-IPF also demonstrates superior overall performance in this study, achieving a maximum Performance Evaluation Criteria of 1.53, thereby establishing itself as the optimal structure.

Abstract
This work aims to investigate how HKUST-1 metal-organic framework (MOF) and Nb2CTx MXene operate in concert to improve the catalytic activity in the hydrogen evolution reaction (HER) and the effectiveness of supercapacitors. While HKUST-1 offers a very porous structure that is favorable for charge storage, Nb2CTx serves as both a conductive substrate and a catalytic site for HER. This combination leads to better charge transfer channels and increased electroactive sites, which ultimately results in higher HER efficiency (shown by a notably lower Tafel slope of 52.42 mV/dec). In configurations of two and three electrodes, a specific capacity of 2168 C/g at a current density of 1.0 A/g is demonstrated by HKUST-1/Nb2CTx Moreover, the theHKUST-1/Nb2CTx combination, in particular the HKUST-1/Nb2CTx//AC composite, shows remarkable stability; after 1000 cycles, they still retain 95 % of their capacity and achieve 97% coulombic efficiency. The HKUST-1/Nb2CTx decorated electrode exhibited energy and power density, reaching approximately 89 Wh/kg and 938 W/kg in two-electrode (real device) configurations. These results highlight the HKUST-1/Nb2CTx composite excellent potential in energy conversion and storage applications.

Abstract
Conversion between different types of entangled states is an interesting problem in quantum mechanics. But research on the conversion between the Greenberger–Horne–Zeilinger (GHZ) state and Knill–Laflamme–Milburn (KLM) state in an atomic system has not been reported. In this paper, we propose a scheme to realize the interconversion (one-step) between the GHZ state and KLM state with Rydberg atoms. By utilizing Rydberg-mediated interactions, we simplify the system. By combining a Lie-transform-based pulse design, the evolution path is built up to realize interconversion of the GHZ state and KLM state. The numerical simulation result shows that the present scheme is robust against decoherence and operational imperfection.

Abstract
The propagation properties of ion-acoustic solitary and shock waves in the magnetized viscous plasma with nonthermal trapped electrons are investigated. The Cairns–Gurevich distribution as the electron distribution is considered to describe the plasma nonthermality and particle trapping. By adopting the reductive perturbation technique, we derived the nonlinear Schamel–Korteweg–de Vries–Burgers (SKdVB) equation, and then obtained the ion-acoustic shock and solitary wave solutions of the SKdVB equation for different limiting cases. It is found that the impact of nonthermal parameter α, external magnetic field Ω, obliqueness l

Abstract
Based on the characteristics of large capacity of high head pumped storage power station in China, by taking CFD technology to carry out optimization design of pump turbine. The hydraulic design and flow characteristic of pump turbine are emphatically studied. In this paper, the hydraulic performance of pump turbine is estimated by numerical simulation method. Based on the runner scheme with the relative guide vane height of b0/D1=0.10, the hydraulic design is carried out to realize the safe and stable operation of the unit within the operating range. Based on the numerical simulation optimization design method, the runner shape, the wrap angle and the setting edge of blade were optimized to improve the hydraulic performance. The final JFP09 pump turbine meets the performance requirements within operating range. The optimized pump turbine can not only meet the performance level of pump flow, hump safety margin and hydraulic efficiency in small flow area, but also satisfy the cavitation performance in large flow area. Meanwhile, the energy matching relation of pump turbine under two-way operation condition can be considered as well. The study result shows that the optimization design based on CFD technique is a reasonable and effective method. The research method will provide guidance for the optimization design of pump turbine.

Published: December 2024

Abstract
Under grid-connected operation, pumped storage - wind power coupling system (PSWPCS) with surge tanks generates the problem of multi-scale oscillation, which leads to the complexity of dynamic response and difficulty of regulation control. Thus, this paper researches the multi-scale oscillation of PSWPCS with surge tanks. Firstly, the mathematical equations of PSWPCS with surge tanks are established. Then, the multi-scale oscillation and effect rules of surge tank area are investigated. Finally, the influence mechanism of multi-scale oscillation is studied. The results indicate that PSWPCS with surge tanks has multi-scale oscillation. The ultra-low frequency damping performance of upstream and downstream surge tanks is stronger than that of single surge tank, and the negative damping characteristics of which changes significantly with the 50% increase of upstream surge tank area. A larger water head of power station and smaller head loss of headrace tunnel are easier to induce the ultra-low frequency oscillation. The pitch angle controller of wind turbine can significantly suppress the low frequency oscillation under larger proportional and smaller integral gain. When proportional and integral gain of phase-locked loop controller are small, the sub-synchronous oscillation will be excited. Smaller stator self-inductance and rotor resistance can improve the system regulation performance.
Transfer and measurement of power plant transients on a high-performance closed-loop test rig
Authors: Geiger C , Kirschner O , Riedelbauch S 
Published: December 2024

Abstract
As hydro power plants become more and more flexible in their operation, the associated transient processes and the resulting loads on the hydraulic machinery are becoming increasingly important. In addition to numerical analysis, measuring of the transient processes using model test rigs plays an important role. The aim is to determine the effects of the transient operating modes in model tests and to transfer the knowledge gained to the prototype. Therefore, the real transient processes of a hydro power plant and the load on the hydraulic machine must first be reproduced on the test rig. The transient turbine start-up of a hydro power plant is analysed in more detail. The first step is to model the entire hydro power plant and calculate the corresponding start-up process. The boundary conditions applied to the hydraulic machine are transferred to the model machine on the test rig using similarity laws; a time scale adjustment is made using the Strouhal number. The time dependent boundary conditions at the model machine are set by varying the rotational speed of a service pump arranged in the test rig and the transient start-up process is measured.
Pelton turbine needle eccentricity leading to asymmetric hydro-abrasive erosion
Authors: Shrivastava Navam , Kumar Rai Anant 
Published: December 2024

Abstract
Hydropower generation of turbines located near geologically young mountain ranges like the Himalayas is challenged by incoming sediment particles. Pelton turbines installed at high heads are significantly affected by hydro-abrasive erosion due to high flow and erosion velocities. The injector of the Pelton turbine is one of the major components of the Pelton turbine affected by hydro-abrasive erosion. Improper installation or manufacturing defect leads to needle eccentricity causing an asymmetric erosion pattern of the injector, thereby reducing jet quality. Here, the effect of needle eccentricity on hydro-abrasive erosion of the injector is numerically investigated by tracking the sediment particles using the Discrete Phase Model (DPM). The intensity and asymmetricity in the erosion of the needle increases with an increase in needle eccentricity. Similar behaviour in the erosion of the needle is observed in reducing the nozzle opening of the eccentrically displaced needle. For a perfectly aligned needle, the average erosion rate in both the upper and lower half region of the needle was identical. However, with 8% of needle eccentricity, the average erosion rate in the upper half region of the needle i.e., towards the displaced side was 89% more compared with the lower half region of the needle. The study emphasises the necessity of inspecting the needle alignment, particularly post-maintenance to mitigate the detrimental effects of hydro-abrasive erosion on Pelton turbine performance.
Onsite performance testing of Archimedes hydropower screw for low head and ultra-low head hydro power project– A case study
Authors: Pillai Deepak S , Stephen Christopher , Tiwari Durgesh K , Singh Manish 
Published: December 2024

Abstract
A low head hydro project refers to hydropower sites operating at head less than 40 m and an ultra-low head refers hydropower sites operating at head less than 3 m or water flow greater than 0.5 m/s with a zero head. These hydro sites though ubiquitous, were not developed at the same pace as medium and high head sites. These sites can play a crucial role in the capacity addition of 45 GW per year for net zero by 2050 according to the International Hydropower Association report. With the introduction of Archimedes screw technology, these sites can be developed both technologically and economically. This paper presents a case study on first of its kind performance testing of electro-mechanical equipment at Archimedes screw projects located in the Vadodara Branch Canal of Sardar Sarovar Narmada Nigam Limited Gujarat. The performance testing was conducted on 4.3 m diameter Archimedes screw designed for a rated head of 6.5 m, and a rated discharge of 7.45 m3/s. The project is designed to deliver 410 kW turbine output, with an inclination angle of 26 degrees from horizontal. The onsite performance study carried out indicates that the achieved Archimedes screw efficiency is 86.6 %.
Assessment of Organic Pollutant Index and Biodegradability Index in Determining River Pollution Load
Authors: Setyawan A , Muhammad F , Hermawan F 
Published: December 2024

Abstract
The Kupang River, a major watershed in Batang and Pekalongan, spans 53 kilometres and has been experiencing significant water quality degradation. Notably, the river’s colour changes to black and emits foul odours, especially during the dry season. This deterioration is attributed to extensive batik industries and residential areas along its banks, leading to severe pollution. This study aims to identify the primary factors contributing to the pollution of the Kupang River from 2021 to 2024 using organic pollutant and biodegradability index. Pollution loads were calculated across five monitoring segments to determine the river’s waste disposal capacity. The findings reveal potential agricultural pollution in the upstream segment, indicated by slow-biodegradable and non-biodegradable degradation. Thus, the downstream segment shows high levels of organic pollution, with degradation ranging from moderate to very strong polluted levels. Pollution load calculations indicate that Kupang River can accommodate pollution loads for TSS up to 30294,49 kg/day, BOD up to 763,03 kg/day, and COD up to 5935,96 kg/day. However, BOD’s low pollution load capacity should be a serious concern, highlighting severe contamination issues that necessitate immediate attention and remediation.

Abstract
Data from the Ministry of Environment and Forestry’s National Waste Management Information System (SIPSN) shows that by 2023, 33.18% or equivalent to 6.5 million tonnes of waste in Indonesia will still accumulate without adequate handling. The continuous accumulation of waste in landfills will produce pollutants in the form of leachate that can pollute groundwater and rivers. Leachate can result in the presence of heavy metals in water, including heavy metals cadmium (Cd) and iron (Fe). This condition is a threat to the ecosystem in river waters and can indirectly have an impact on human health. This study aims to determine the content of heavy metals cadmium (Cd) and iron (Fe) in the river around the Putri Cempo landfill in Surakarta City, Central Java. The sampling point is at coordinates 7°32′14.4 ‘S 110°51′30.0 ’E, then testing for heavy metal content using the Atomic Absorption Spectrometry (AAS) method. The results showed that the cadmium (Cd) content in the river water was relatively low at -0.0274876 mg/L. This is caused by several factors, namely the nature of Cd which is not easily soluble in water so that it easily settles into sediment, the dilution of river water by rain, and the river is far from the industrial area. In contrast to Cd, iron (Fe) levels in river water far exceed the safe limit of 7.98940397 mg/L. This indicates that the river water in the area has been heavily polluted by heavy metal iron (Fe). The high levels of iron (Fe) are caused by the disposal of iron-containing domestic waste, the presence of iron water reservoirs in the Putri Cempo landfill, and corrosion of water pipes that contain iron (Fe).

Published: December 2024

Abstract
Utilization of MSWI fly ash and corncob by combining fly ash and corncobs with a 1:10 ratio, activated with 75% KOH as an adsorbent to reduce methylene blue dye in textile wastewater. For the characterization testing of FACC, SEM-EDS, and pHpzc were used to determine the morphological conditions and pH value when FACC is in zero charged condition. Characterization results show that FACC has a rough surface and many pores with O, C, and K as dominant elements. pHpzc test shows that FACC will have a zero charge at pH 13.18. Experiments were conducted with batch method on the effect of adsorption operational parameters at contact time (0-120 min), FACC dosage (0.05-0.5 g/L), pollutant concentration (50-250 mg/L), and initial pH (2-10). Maximum removal efficiency was obtained at a contact time of 60 minutes, with a dosage of 0.5 g/L, pollutant concentration of 50 mg/L, and initial pH of 4 with a removal % of 98.37%. The Langmuir isotherm model described the adsorption mechanism with the maximum adsorption capacity reaching 344.828 mg/g. The adsorption rate used a pseudo-second-order kinetics model with a K2 value of 13.9 × 10−3 g/mg.min. FACC are good adsorbent alternatives for removing dyes in industrial wastewater.

Abstract
Microplastics have negative chemical and ecological effects on aquatic biota and humans. However, few studies have explored the abundance of microplastic in rural river. This study aims to compare of the abundance of microplastic, size distribution, color, and polymer types in rural river of Japan and Indonesia. Data were collected at one of river point in the in the Hamada River, Japan during dry season and Mlese River, Indonesia during rainy season. The sampling and analysis methods were in accordance with the Japanese Riverine Microplastic Survey Guidelines, the microplastics in the range of 500-5,000 μm were determined by optical microscopy and FTIR spectroscopy. Film shaped, size 1,000-3,000 μm, and polymer type polyethylene and polypropylene were the majority of the identified microplastics both in Hamada River and Mlese River. Meanwhile, the dominated colors were gray for Hamada River and transparent for Mlese River. The abundance of microplastic were 5.5×10−2 particles/m3(discharge:0.032 m3/s) for Hamada River and 2.2×10−3 particles/m3 (discharge:8.12 m3/s) for Mlese River. A low abundance of microplastic in Mlese River is a result of the high flow velocity and discharge. Moreover, that shows Hamada River’s microplastic is 26 times greater, this indicates that Japan uses more plastic products to support crop production compared to Indonesia and influence the river water pollution by microplastics.
