AbstractThis study reports an effective strategy for designing 3D electrocatalyst via the deposition of ZIF67‐derived Co–CN shell layer over CuO nanoarrays to form a CuO@Co–CN hybrid, followed by incorporation with p‐block Sb single atoms (CuO@Co–CN/Sb) to obtain highly activated catalytic behaviors. Inheriting both the excellent intrinsic catalytic activity of the components and their synergy, the CuO@Co–CN/Sb material serves as a high‐efficiency multifunctional catalyst for overall water splitting and zinc (Zn)–air batteries. The material yields a current density of 10 mA cm−2 at a low overpotential of 72 and 250 mV for the hydrogen evolution reaction and oxygen evolution reaction, respectively. Furthermore, an electrolyzer based on CuO@Co–CN/Sb shows remarkable performance with a derived current density of 0.5 A cm−2 at low cell voltage of 2.67 V and good stability for 50 h continuous operation at a high current density of 0.5 A cm−2. Simultaneously, Zn–air battery using the CuO@Co–CN/Sb material as air cathode yields a high open circuit voltage of 1.455 V and a discharge power density of 131.07 mW cm−2.

Published: December 2024

AbstractThis is the first documented case of scent triggering episodes of feline hyperaesthesia syndrome (FHS). A 1‐year and 5‐month‐old cat was referred to the feline clinic with a 5‐month history of generalised twitching of the dorsum, vocalising, compulsive grooming and darting/running episodes. A diagnosis of FHS was made following exclusion of other differential diagnoses. The cat had co‐morbid behaviour problems and was referred to the behaviour clinic. Triggers for FHS were explored: most episodes were unpredictable and without a consistent trigger; the cat was diagnosed with attention seeking and frustration‐related problems. A behaviour modification programme was developed, and a detailed diary was kept. Improvements were reported in general behaviour, as well as frequency and intensity of episodes of FHS. Episodes of FHS continued sporadically and were clearly linked to scent triggers (scented candles, cigarette smoke, cooking spices). Scent should be therefore be considered as a potential trigger for episodes of FHS.

AbstractThe case illustrates that the patentee’s possibilities to avoid exhaustion by tailoring the patent claims are limited. It is generally up to the patentee to define the product for which he claims protection. As long as the patent covers products which are available on the market, the patentee’s decision may be relevant for the question of exhaustion.
Service Life Prediction of Fatigue Damaged Reinforced Concrete Beams Under Seawater Erosion and Freeze–Thaw Cycles
Authors: Liu Zijian , Cao Huiyun 
Published: December 2024

AbstractA reasonable and applicable chloride ion diffusion model for fatigue damaged concrete structures exposed to seawater freeze–thaw environments was proposed, And the service life of reinforced concrete beams with fatigue load levels of 0.2 and 0.3, fatigue loading times of 200,000–400,000 under seawater immersion alternating freeze–thaw cycle environment were predicted. Results show that the expected service life of concrete beams without fatigue damage under seawater immersion alternating freeze–thaw cycle was 6.0 years, respectively, which was far less than the requirements of existing specifications for the service life of concrete structures. The service life of concrete structures further decreased as the fatigue load increased. For concrete beams with a fatigue load level of 0.3 loaded 400,000 times, under the alternating freeze–thaw cycles of seawater immersion, the expected service life is only one year.

The flutter type of the bridge is a damp driving in which the reversal of implicated movement is dominant. The performance of the main beam flutter was improved through increasing torsional movement of pneumatic positive damping A and reducing torsional coupling movement implicated generated aerodynamic negative damping term D. The degree of participation of the vertical bending freedom and the bending-torsion coupling was increased when the flutter occurs of the partly closed railing aerodynamic measures beam, and the fluttering shape was transferred from the single degree of freedom torsional vibration to the bending and torsional coupled vibration. Thereby, the flutter frequency was reduced and the critical flutter wind speed was improved.

Effect of Pit System Stiffness on Force and Deformation of Adjacent Monopile
Authors: Jiang Minmin , Wang Di , Li Yu , Xiao Zhaoran 
Published: December 2024

AbstractThe soil displacement caused by the foundation excavation will impose additional stresses on the pile foundations within its influence range, resulting in lateral displacement or insufficient bearing capacity of the pile foundations, which will adversely affect the pile foundations and cause uneven settlement of the structures in the long run, triggering local damage to the soil below the pile foundations and even distorting the deformation of the upper structures, affecting their safety in use. In this paper, the two-stage method is used to analyze the lateral displacement of pile foundations. The free displacement field of the soil during the excavation of the foundation pit is used as the input condition, and the lateral displacement and internal force of the monopile are solved by introducing the improved foundation reaction modulus into the Winkler foundation model. Combined with the numerical model, the effects of pit excavation on the surrounding soil, supporting structure, and adjacent pile foundations are investigated. The effects of different factors on the force and deformation pattern of pile foundations are analyzed, the degree of influence of different comprehensive stiffness of pit support on pile foundations is explored, and the comprehensive stiffness is related to the maximum horizontal displacement of pile foundations to propose a method for predicting the maximum horizontal displacement of pile foundations, which can be a reasonable reference for similar pile foundation projects.

AbstractThe dynamic response of underground structures under blast loading is of great military significance to strategically valuable targets, and the difference in the dynamic response of underground structures at different blast angles is investigated based on a FEM-DEM coupled method. First, a full-time numerical simulation under blast loading is carried out. Then, the displacement and fracture characteristics of the underground structure are analyzed quantitatively. The results indicate that the spatial distribution of displacement and initial fracture type is closely related to the position of the explosive. The concrete at the top boundary and right boundary reaches the opposite boundary earliest at 90° and 0° respectively. The time-history curves of crack ratio have obvious stage characteristics, the maximum tensile crack ratio is obtained at 90°, and the maximum shear crack ratio is obtained at 0°.

Authors: Di Jiaxing 
Published: December 2024

AbstractIn the event of an accidental collapse of the main plant of the conventional island, it could threaten the safe operation of the nuclear island and even cause a nuclear leakage accident. Therefore, the study of the collapse resistance of the main plant structure of a conventional island nuclear power plant should be of great interest. In this paper, the collapse resistance of conventional island main plant structure is analyzed by Pushdown analysis method, and the damage of beam and column members and the position of plastic hinge when the conventional island main plant structure is subjected to accidental action are simulated by the method of removing members. The analysis results show that the damage of the column increases with the increase of the column span after the removal of the corner columns, and the structural displacement of the upper floors within the beams and failed columns connected to the control nodes will be dispersed with the increase of the vertical load, and the damage will spread to the top of the structure; It can be concluded from the order of the appearance of the plastic hinge: the main plant structural system conforms to the principle of “strong columns and weak beams”, so the main nuclear power plant conventional island studied in this paper The progressive collapse resistance of dismantled corner columns of the structural system of plant has certain guiding significance for practical engineering.

Authors: Ge Tao , Liu Chenxi 
Published: December 2024

AbstractTo study the durability of concrete structures against chloride ions penetrations under subway environmental conditions, permeability performance tests were conducted on high-performance concrete using the conductivity method and corrosions method, respectively. The experimental results show that the additions of fly ash, slag, and other admixtures in high-performance concrete have a significant effect on resisting the infiltrations and diffusions of chloride ions into the concrete. Considering the long-term durability of chloride ions penetrations, high-performance concrete with dual additions of fly ash and slag has better durability improvement than single additions. The durability life of high-performance concrete in chloride ions resistance test is 3–4 times longer than that of ordinary concrete.

Published: December 2024

AbstractPumped storage plants usually occupy a large area and contain multiple components and facilities. The details and actual geomorphological features of the entire area are taken into account when modeling to provide comprehensive visualizations. However, dealing with large-scale scenarios increases the amount of data and computational complexity, further increasing the difficulty. Therefore, a new 3D visualization modeling method of pumped storage power plant is designed. BRCM software is selected as the 3D visualization dynamics modeling and analysis software to form an effective 3D visualization modeling design flow, transient analysis of 3D nonlinear dynamics, optimization of the accuracy of real scene 3D modeling, and finally the realization of 3D visualization modeling. The result of case analysis shows that the designed 3D visualization modeling method of pumped storage power plant has high modeling precision, good modeling effect, reliability, and certain application value, and has made a certain contribution to improving the operation safety of pumped storage power plant.

Authors: Bai Jianguang , Zhou Tianping 
Published: December 2024

AbstractWith the rapid development of high-rise buildings and infrastructure construction, higher requirements for foundations have been put forward. Cement fly-ash gravel pile is widely used in foundation treatment projects because of their high bearing capacity, low settlement, and low cost. The article adopts FLAC3D to conduct a numerical simulation study of the deformation characteristics of cement fly-ash gravel pile, the results show that cement fly-ash grave pile composite foundation produces vertical displacement with obvious zoning phenomenon under the action of upper load, horizontal displacement mainly occurs in the area of soil between piles, and the soil is extruded dense. The displacement and separation phenomenon of the interface of cushion and foundation are significantly different in the position of the pile and the position of soil between piles. The deformation of the CFG pile composite foundation is influenced seriously by the cushion as the weak zone of the CFG pile. The findings provide a reference and basis for the design and application of cement fly-ash gravel piles.
Numerical Simulation of the Effect of Joint Parameters on the Mechanical Behaviors of the Fractured Sandstone
Authors: Zhang Yue , Du Miaoran , Yin Peijie 
Published: December 2024

AbstractJoint parameters affect the mechanical properties of sandstone significantly. This paper investigates the influence of fracture on the mechanical properties of roof plate bedded sandstone in Yuanjue Cave by using the Discrete Fracture Network (DFN) model. The effects of joint density and dip on the mechanical behavior of bedded sandstone under triaxial compression are first examined. And, the fractal dimension is used to quantify the relationship between joint density and strength parameters. The results show that: (1) The compressive strength and elastic modulus of bedded sandstone decrease with increasing joint density. The compressive strength shows a ‘U’ distribution with increasing joint dip from 0° to 90°, while the elastic modulus increases gradually. (2) The bedded sandstone shows a very high anisotropic characteristic, and the weak plane of the layers influences the strength and deformation damage of the bedded structure. (3) The fractal dimension has a significant negative correlation with rock strength and elastic modulus, with correlation coefficients of 0.834 and 0.965.
Novel endophytic fungus Leptosphaeria sp. strain T-2 improves plant growth and environmental stress tolerance
Authors: Yamaguchi Taku , Kataoka Ryota 
Published: December 2024

AbstractDrought and salinity stress pose threats to agricultural production in drylands. Although breeding and genetic modification techniques have been employed to develop drought- and salt-tolerant crops, these methods are costly and risky. Hence, the potential application of endophytic fungi in dryland agriculture is being explored as a novel approach in improving plant tolerance to environmental stress. In this study, endophytic fungi with growth-promoting effects were isolated, characterized, and evaluated in terms of their ability to confer drought and stress tolerance to their host plants. Seventy-seven growth-promoting endophytic fungi belonging to 20 genera were isolated from barley roots; of these, strain T-2 elicited remarkable effects on plant growth parameters. Phylogenetic analysis revealed that strain T-2 belongs to genus Leptosphaeria, whose members are generally known as plant pathogens. Thus, Leptosphaeria sp. strain T-2 is a novel endophytic fungus that promotes plant growth. Moreover, it alleviated growth inhibition caused drought and salinity stress, as evidenced by the survival and maintained health of lettuce plants inoculated with strain T-2. The results of this study suggest that strain T-2 can be applied as a biofertilizer to improve agricultural production in drylands.
The multiple meanings of EU law: using sociological interpretivism to make sense of the Eurozone crisis
Authors: Haagensen Nicholas 
Published: December 2024

AbstractIn following the interdisciplinary spirit of this symposium, I emphasise the usefulness of the sociological approach of interpretivism, together with qualitative methods, by examining how EU legal actors perceived the Eurozone crisis and how they enabled policy solutions: financial assistance and policy conditionality. This case constitutes a legal conundrum because of how these solutions encompass and connect different forms of law – EU law, international law and private financial law – and how EU lawyers seek to protect the EU legal order from this hybrid arrangement by drawing the arrangement as closely as they can to the EU legal order. This in turn creates issues of accountability as the imposition of policy conditionality engenders litigation by EU citizens who were directly affected therein, raising the question of whether establishing liability for damages is possible in such a hybrid arrangement. Using interviews with legal actors and observations of court proceedings, I foreground the multiple meanings of EU law and explain how such an approach can expand our understanding of not only what EU law means to its practitioners, but also how these meanings give insight into the potential paths of EU law’s development. To interrogate these multiple meanings, I examine the crisis policy solutions as well as a set of court cases – Ledra Advertising, Mallis and Chrysostomides – that sought to hold the EU accountable for losses suffered because of these policies. Using these methods can partially overcome the opaqueness of judicial proceedings at the EU level, as well as give insight into the development of the legal arrangements being contested in court. A novel methodological element is the descriptive analysis of observations of court proceedings in Chrysostomides, where I demonstrate how the interactions between the lawyers and the judges shed light on how legal actors establish legal validity as a collective project.
Political, not (just) legal judgement: studying EU institutional balance
Authors: van den Brink Martijn 
Published: December 2024

AbstractThis article presents two related arguments. First, the limits of doctrinal analysis cut deeper than many EU lawyers realise. Most would probably accept that legal doctrine does not determine every legal dispute, but lawyers studying EU institutional balance often still assume that it can be deduced from the positive law what is good institutional practice. This paper argues instead that the allocation of EU institutional authority cannot be determined by the exercise of legal judgement, but instead requires the exercise of political judgement on the relative merits of different institutions. Second, this means that political and normative discourses and disciplines cannot be assumed to fall outside the domain of legal scholarship. What we need instead is a distinctive kind of legal scholarship that interweaves doctrinal analysis with normative political theory, broadly conceived. I will argue that political theory, in addition to evaluative value, has adjudicative value, provided that our theories are sensitive to the EU’s social and political setting and the constraints this setting imposes on what is realistically feasible.

An Oligocene chimaeroid egg capsule from western Washington State, USA, and priority of Vaillantoonia Meunier, 1891
Authors: Kiel Steffen , Stevens Thomas , Goedert James L. 
Published: December 2024

Fossil egg capsules of chimaeroids (holocephalian fishes), although rare, have been known for more than 150 years (Bessels, 1869; Meunier, 1891a) and have been found in rocks as old as Upper Triassic (Gottfried and Fordyce, 2014). Egg capsules of extant chimaeroids are spindle shaped, with a smooth central body where the embryo develops, an elongate anterior beak through which the hatchling emerges, and an elongate posterior pedicle. The capsules are flanked by a lateral membrane or web on both sides, and the web is reinforced with branching or unbranching rib-like costae that extend laterally from the central body, beak, and pedicle. Specimens are typically about 10–30 cm long. Egg capsules of extant chimaeroids are made of collagen (Hamlett et al., 2005) and as fossils, chimaeroid egg capsules are typically preserved as external casts (Fischer et al., 2014).
