Abstract
Rare earth ion doped GdVO4 phosphors have been used in laser, luminaire, luminescent display and other fields, but there are few reports for latent fingerprint. In this paper, a series of Bi3+ and Re3+ (Re = Eu, Dy, Tm) singly doped GdVO4 and Bi3+ and Re3+ double doped GdVO4 phosphors were synthesized by high temperature solid method. The structure and characteristics of luminescence were described by X-ray powder diffraction and photoluminescence spectrum. We tried to apply prepared phosphors to the latent fingerprint detection field, and found that GdVO4: Bi3+, Eu3+ phosphor has lower background interference, and can effectively display latent fingerprint details under different surfaces, wet environments and high temperature conditions. The Bi3+, Eu3+ co-doped GdVO4 phosphor is a promising phosphor material for latent fingerprint identification application.

Published: December 2024

Abstract
The present study investigates compatibility of high-viscosity additive (HVA) and SBS-modified asphalt (SBSMA). The compatibility between HVA and SBSMA is evaluated through toughness and tenacity of high-viscosity modified asphalt (HVMA) and the Cantabro loss of porous asphalt mixture (PAM), respectively. The results show that the compatibility of HVA and SBSMA is influenced by the crosslinking state of SBS in SBSMA. The compatibility between HVA and SBSMA is adversely affected by excessive or insufficient crosslinking density. The optimal compatibility between HVA and SBSMA can be achieved when the SBSMA contains moderate crosslinked SBS.

Published: December 2024

Abstract
In order to improve the problems of poor stability, low flowability, and weak corrosion inhibition of the grouting material, sodium lignosulfonate (SL) was used as a modified component of the pore grouting material in this paper. The non-uniformity coefficient was introduced to evaluate the stability of the grouting material. And, macro and micro experiments were used to comprehensively evaluate the influence of sodium lignosulfonate on the flowability, stability, strength, and corrosion inhibition of the grouting material, revealing the mechanism of SL’s modification effect on the pore grouting material. The results show that the addition of SL can significantly improve the stability of the grouting material. When the dosage is 4%, the mechanical properties of the grouting material are optimal; The addition of SL can significantly reduce the corrosion products on the surface of steel strand samples, and the research results provide data support and technical guidance for the application of SL in grouting materials.

Analysis on Contact Pressure for the Seal Structure of Repair Clamp with Wedge Contact Seals
Authors: Zhao Zhangfan , Shi Xiang 
Published: December 2024

Abstract
Seal pressure is the key performance of repair clamp for subsea pipeline, which is generally designed by analyzing the contact pressure on each sealing surface of the seal structure. Research has shown that the weakest part of the clamp seal is the position where radial seal ring contacts axial seal strip. Usually for clamp seal structure the contact between radial seal ring and axial seal strip is tangent between a cylindrical surface and a plane. In order to improve the contact pressure of the position, a seal structure with wedge contact between seals that is tangent between a conical surface and a plane is proposed. 3D simulation analysis for the seal structure is carried out, and the contact pressures under four different wedge angles of 11°, 13°, 15° and 17° are analyzed. The minimum contact pressure is compared with that of the wedge angle of 0°. Simulation results show that the wedge contact will increase the contact pressure of the original weakest part, and the position of minimum effective contact pressure of the seal structure becomes the contact surface between two seal rings. The minimum contact pressure increases with the increase of the wedge angle. The wedge angle is recommended to be 13 ° more appropriate.

Published: December 2024

Abstract
Flowable fill has been widely used as a type of fill materials in engineering practice. However, the adoption of fine-grained soils, especially clay soils, in flowable fills faces difficulties such lack of mixing efficiency and poor engineering performance. In this study, the flowable fill was prepared using waste excavated soil generated from a construction project. Two types of soils, silty clay and silt mixed with silty sand, were used. In the laboratory tests, slump tests, unconfined compressive tests, oedometer compression tests, and drying shrinkage tests were conducted. Within the tested condition (8-10% cement addition and 10-50% water addition), the range of slump was 70-203 mm, and the range the 28d strength was 0.39 -0.67 MPa. For this project and most construction applications, these level of slump and strength are satisfactory. The construction process using the flowable fill has four steps, that is, raw soil filling, cement slurry preparation, flowable fill mixing, and conveying and filling. The details and the problems in the construction are introduced and discussed. Field experiments also confirmed that parameters such as slump, strength, deformation, can meet the design requirements.

Abstract
In recent years, with the development of the economy and the improvement of living standards in rural areas of China, the production of rural domestic sewage has increased sharply. However, the construction of sewage treatment facilities in rural areas lags behind, leading to a relatively low rate of rural domestic sewage treatment and highlighting ecological issues in rural areas. In order to govern rural domestic sewage in a targeted manner and improve treatment efficiency, it is necessary to conduct investigations on the water quality, water quantity, discharge patterns, and composition of pollutants of rural domestic sewage. This is to provide references for the selection of rural domestic sewage treatment technologies.

Abstract
We employed sodium lignosulfonate grafted sodium polyacrylate resin for the adsorption treatment of leachate from a landfill Fushun City, China. We obtained the resin’s removal rates of Pb2+, Cu2+, COD, and NH3-N and used them to examine how adsorbent dosages, pH levels, and oscillation times affect its performance in treating leachate in wastewater. According to the experimental results, its performance in adsorbing heavy metal ions, particularly Pb2+ and Cu2+, in the leachate from waste, was considerably improved. The optimal comprehensive treatment results were obtained with a pH of 4.5, an adsorbent dosage of 55 mg, and an oscillation time of 80 minutes, with the removal rates being 91.3% and 89.6%, respectively, for Pb2+ and Cu2+. The adsorbent resin exhibited certain removal capabilities for COD and NH3-N, although not to the same extent as observed for heavy metals.

Abstract
The compressive strength along the grain (CSAG) is one of the important mechanical properties in design for wood structural materials. Taxodium ascendens Brongn is one of the important timber species planted in the water network area of the Yangtze River basin in China. In this paper, its radial and axial variation of the compressive strength along the grain within and among trees in Taxodium ascendens plantation. The results show that the CSAG variation of Taxodium ascendens increase in radial direction with a tree age and first increases, then decreases and fially keep stable. The axial variation of CSAG first increases, then decreases and stabilize from base of a tree to top. There is a clear positive correlation of its CSAG with extractives content, which reflected that the variation of its CSAG is mainly influenced by the content of extractives. There are significant differences in CSAG among trees of Taxodium ascendens and different heights a tree. The average of its CSAG is 35.37 MPA, with a range of 25.05-47.34 MPa. According to the standard data of Chinese wood properties, its CSAG is relatively small and its timber is soft in hardness. It can be used as general furniture material and is not suitable as a load-bearing lumber
Using Quantum Switches to Mitigate Noise in Grover's Search Algorithm

Published: December 2024

Abstract
Grover's quantum search algorithm promises a quadratic speedup for unstructured search over its classical counterpart. But this advantage is affected by noise acting on the search space. Here, we show that a quantum switch can act as a resource to mitigate the effects of noise. In this scenario, the noise is modeled by a depolarizing channel, which coherently acts on the entire quantum register. &#xD; &#xD;We show that a quantum switch can significantly reduce the error in Grover's search algorithm. We consider the success probability of finding the marked item as the sole quantifier of diminishing the effect of noise in the search space in the presence of quantum switch. We propose two frameworks for the application of quantum switches. In the first framework, we apply the superposition of channel's orders in the form of a switch and do a post-selection at every iteration of the applications of the Grover operator.&#xD;In the second framework, we delay this measurement and post-selection until the very end. &#xD;&#xD;The number of post selections is minimal in the second scenario, and hence the noise reduction can be attributed more to the presence of quantum switch. &#xD; &#xD;We illustrate with an example of significant advantage in the success probability of Grover's algorithm using quantum switch.

Published: December 2024

Abstract
Since the establishment of the green campus concept at the end of the 20th century, global awareness of its implementation has steadily increased. This study was a narrative review that explored the implementation and challenges of green campuses in Indonesia, focusing on education and research. Data were collected through a literature review using the UI Green Metric website, university green campus websites, and articles from Google and Google Scholar. The criteria for source selection included: (1) publication between January 2010 and January 2024, (2) data sources limited to journal articles, excluding theses and dissertations, (3) articles that mentioned green campus programs in education and research, (4) research conducted at Indonesian campuses, and (5) sources that could be either research journals or review articles. A total of 50 articles were analyzed qualitatively. The results indicated an increase in the number of Indonesian campuses implementing green campus programs from 2018 to 2023. Only 4% of Indonesian campuses had effectively implemented programs in education and research, based on articles and reports from the UI Green Metric website. The challenges faced included limited academic involvement due to a lack of awareness, insufficient policies and regulations, inadequate research funding, and a scarcity of relevant courses. This study concluded that the implementation of green campuses in Indonesia, particularly in research and education, remained ineffective. Significant development is necessary to advance sustainable and environmentally friendly education and research practices in Indonesian campuses.

Published: December 2024

Abstract
The study aimed to determine the optimal yeast concentration and growth pattern using the yeast growth curve and to evaluate bioethanol yield from molasses through fermentation with varying Brix levels and yeast concentrations. Bioethanol was produced from sugar mill molasses using Saccharomyces cerevisiae, which converts sugars into ethanol and carbon dioxide. Variations in Brix levels and yeast concentrations influence alcohol yield and volume, necessitating further research to identify optimal conditions for efficient bioethanol production. Seven yeast concentrations (1%, 1.5%, 2%, 2.5%, 3%, 3.5%, and 4%) were tested by measuring optical density (OD) to select the optimal concentration. This concentration was then applied in fermentation with Brix variations of 15%, 17%, and 19% for 72 hours, followed by distillation to obtain bioethanol. Ethanol content was measured using a UV-Vis spectrophotometer, resulting in bioethanol yields of 0.145%, 0.166%, and 0.180% for 15%, 17%, and 19% Brix, respectively. The highest ethanol content (0.180%) was achieved with 19% Brix and 4% yeast concentration after 8 hours of fermentation. These findings are expected to improve the efficiency of bioethanol production from molasses, supporting renewable energy development and reducing reliance on fossil fuels.

Published: December 2024

Abstract
Optical phased array (OPA) has emerged as a promising technology for a wide range of applications ranging from LIDAR for autonomous vehicles, space communication, laser machining to augmented reality. Metasurfaces have the potential to greatly improve the performance of OPAs and extend their range of applications. Although metasurface OPAs have found applications mostly in conventional optics so far, they have also shown great promise for application in light emitting devices and quantum optics in recent years. This paper presents a review of the state of the art of metasurface OPAs for both conventional and emerging applications. Major progress made in recent years and the important challenges that need to be addressed are discussed.
An operational definition of quantum information scrambling

Published: December 2024

Abstract
Quantum information scrambling (QIS) is a characteristic feature of several quantum systems, ranging from black holes to quantum communication networks. While accurately quantifying QIS is crucial to understanding many such phenomena, common approaches based on the tripartite information have limitations due to the accessibility issues of quantum mutual information, and do not always properly take into consideration the dependence on the encoding input basis. To address these issues, we propose a novel and computationally efficient QIS quantifier, based on a formulation of QIS in terms of quantum state discrimination. We show that the optimal guessing probability, which reflects the degree of QIS induced by an isometric quantum evolution, is directly connected to the accessible min-information, a generalized channel capacity based on conditional min-entropy, which can be cast as a convex program and thus computed efficiently. By applying our proposal to a range of examples with increasing complexity, we illustrate its ability to capture the multifaceted nature of QIS in all its intricacy.

Abstract
Quantum chemical calculations are among the most promising applications for quantum computing. Implementations of dedicated quantum algorithms on available quantum hardware were so far, however, mostly limited to comparatively simple systems without strong correlations. As such, they can also be addressed by classically efficient single-reference methods. Here we calculate the lowest energy eigenvalue of active space Hamiltonians of industrially relevant and strongly correlated metal chelates on trapped ion quantum hardware, and integrate the results into a typical industrial quantum chemical workflow to arrive at chemically meaningful properties. We are able to achieve chemical accuracy by training a variational quantum algorithm on quantum hardware, followed by a classical diagonalization in the subspace of states measured as outputs of the quantum circuit. This approach is particularly measurement-efficient, requiring 600 single-shot measurements per cost function evaluation on a ten qubit system, and allows for efficient post-processing to handle erroneous runs.

Abstract
Most net-zero emissions targets require electrification of the entire light-duty vehicle fleet, and before that the electrification of all new vehicle sales. In this paper, we review literature on demand-side issues related to achieving 100% zero-emissions vehicle sales, focusing on plug-in electric vehicles (PEVs). We discuss potential demand-side challenges to increasing PEV sales and related research gaps, including consumer factors (perceptions, knowledge, and consumer characterises), demand-focused policy (incentives), infrastructure, and energy prices. While global PEV sales have substantially increased in recent years, several challenges remain: some demographic groups are currently underrepresented among PEV buyers (e.g. renters, lower income buyers), some car drivers are resistant to PEVs, incentives are influential but have predominantly benefited higher-income new-car buyers and are being phased out, infrastructure is not sufficiently developed or equally distributed, infrastructure is not user friendly, and some households lack charging access. Some issues we identify may be related to the early stage of the PEV market, though will need to be addressed to reach higher PEV sales and PEV fleet shares. Finally, we outline areas where more research is needed to understand and guide the PEV transition.
