Authors: Xu Guangli , Wang Yifu , Zhou Zhihao , Lu Yifeng , Cai Liangxue 
Published: January 2025

Abstract
As a necessary part of intelligent control of a joint station, the automatic identification of abnormal conditions and automatic adjustment of operation schemes need to judge the running state of the system. In this paper, a combination of Particle Swarm Optimization (PSO) and Gray Wolf Optimizer (GWO) is proposed to optimize the Backpropagation Neural Network (BP) model (PSO-GWO-BP) and a pressure drop prediction model for the joint station export system is established using PSO-GWO-BP. Compared with the traditional hydraulic calculation modified (THCM) models and other machine learning algorithms, the PSO-GWO-BP model has significant advantages in prediction accuracy. Based on the PSO-GWO-BP pressure drop prediction model, the determination method of state identification threshold is established, and a state identification method based on dynamic threshold is proposed, which realizes the intelligent identification of the system operation state by automatically adjusting the threshold. Through the analysis of the production and operation data of the joint station, the abnormal working conditions are successfully identified, and the effectiveness and accuracy of the method are verified. This method not only enhances the ability to discriminate abnormal working conditions but also adaptively adjusts the operation scheme, which effectively improves the intelligence level of the joint station export system.

Abstract
Photosynthetic activity is established during chloroplast biogenesis. In this study we used 680 nm red light to overexcite Photosystem II and disrupt photosynthesis in two conditional mutants (var2 and abc1k1) which reversibly arrested chloroplast biogenesis. During biogenesis, chloroplasts import most proteins associated with photosynthesis. Some of these must be inserted in or transported across the thylakoid membrane into the thylakoid lumen. They are synthesized in the cytoplasm with cleavable targeting sequences and the lumenal ones have bi-partite targeting sequences (first for the chloroplast envelope, second for the thylakoid membrane). Cleavage of these peptides is required to establish photosynthesis and a critical step of chloroplast biogenesis. We employ a combination of Western blotting and mass spectrometry to analyze proteins in var2 and abc1k1. Under red light, var2 and abc1k1 accumulated incompletely cleaved processing intermediates of thylakoid proteins. These findings correlated with colorless cotyledons, and defects in both chloroplast morphology and photosynthesis. Together the results provide evidence for the requirement of active photosynthesis for processing of photosystem-associated thylakoid proteins and concomitantly progression of chloroplast biogenesis.

Abstract
Monocarpic plants flower only once and then produce seeds. Many monocarpic plants require a cold treatment known as vernalization before they flower. This requirement delays flowering until the plant senses warm temperatures in the spring. Exposure to high temperatures following vernalization causes devernalization, which cancels the vernalized state, inhibiting flowering and promoting vegetative growth. In this study, we screened over 16,000 chemical compounds and identified five small molecules (devernalizers; DVRs) that induce devernalization in Arabidopsis thaliana at room temperature without requiring a high-temperature treatment. Treatment with DVRs reactivated the expression of FLOWERING LOCUS C (FLC), a master repressor of flowering, by reducing the deposition of repressive histone modifications, thereby delaying flowering time. Three of the DVRs identified shared two structures: a hydantoin-like region and a spiro-like carbon. Treatment with DVR06, which has a simple chemical structure containing these domains, delayed flowering time and reduced the deposition of repressive histone modifications at FLC. RNA-seq and ChIP-seq analyses revealed both shared and specific transcriptomic and epigenetic effects between DVR06- and heat-induced devernalization. Overall, our extensive chemical screening indicated that hydantoin and spiro are key chemical signatures that reduce repressive histone modifications and promote devernalization in plants.

Published: January 2025

Abstract
Objective To determine the effect of locking head inserts (LHI) on plate strain, stiffness, and deformation when applied to a 3.5-mm broad locking compression plate (LCP) in an open fracture-gap model.
Study Design Six, 13-hole, 3.5-mm broad LCP were secured to epoxy bone models with a 10 mm central defect and 1 mm plate offset. Two peripheral locking screws were placed in each segment, with the remaining screw holes left unfilled. Three strain gauges were glued to each LCP at anticipated regions of maximum strain. Constructs underwent cyclic uniaxial loading at a rate of 20 mm/min to 400 N in three different configurations (Configuration 1: no LHI, Configuration 2: 3 LHI, Configuration 3: 9 LHI). LHI were tightened to 4 Nm of torque. A data acquisition system was used to collect implant strain during testing. Construct stiffness and deformation were recorded by the biomechanical testing machine.
Results Maximum implant strain was recorded at the central screw hole directly over the simulated fracture gap in all configurations (Mdn 1,837.3 µε [interquartile range: 1,805.1–1,862.0]). There was no difference in implant peak-to-peak strain with addition of LHI at all three gauges (Gauge 1 [p = 0.847], Gauge 2 [p = 0.847], Gauge 3 [p = 0.311]). Similarly, peak-to-peak displacement (p = 0.069) and axial construct stiffness (p = 0.311) did not change with the addition of LHI.
Conclusion The addition of LHI to a 3.5-mm broad LCP construct was not shown to have an effect on plate strain, stiffness, or deformation.
CO2 Laser Technique versus Cold Steel: Is CO2 Laser Required as a Surgical Tool for Flawless Stapes Surgery?
Authors: Kumar Vikas , Gupta Anandita , Sethi A. 
Published: January 2025

Abstract
Introduction Stapedotomy is the standard of care in the surgical management of clinical otosclerosis. It is a precise and technically demanding craft requiring impeccable surgical skills. Both conventional and laser-assisted procedures aim to achieve closure of the air-bone gap (ABG) with minimum collateral damage.
Objective To compare the postoperative outcomes of conventional stapes surgery and CO2 laser-assisted surgery.
Methods We conducted a retrospective analysis of the medical records of 74 adult patients who underwent stapedotomy at our center. The patients were divided into two groups for comparison: the “cold steel method” (CSM) group, which was composed of patients who had undergone conventional stapedotomy (manual microperforators/hand-held microdrill); and the “CO2 laser-assisted” (LA) group. The postoperative outcomes assessed at 3 and 6 months in both groups were analyzed and compared. The average operative time and complications of both groups were also compared.
Results The hearing outcomes presented statistically significant postoperative improvement in both groups. The LA group presented statistically significant better air conduction thresholds at 3 and 6 months (p < 0.05). The ABG and its degree of closure were statistically better at 3 months in the LA group; however, the difference became insignificant at 6 months. Transient vertigo was more common in the LA group (p < 0.01). There was no new sensorineural hearing loss in either group. The operative time was longer in the LA group.
Conclusion In experienced hands, both conventional and laser techniques can be used with equal ease and expectation of better outcomes. The CO2 laser is not an indispensable tool to achieve good surgical results on a routine basis.

Published: January 2025

Abstract
Cognitive mapping is central to urban design. As a pioneer of cognitive mapping, Kevin Lynch focused his work on tangible visual elements while only acknowledging other intangible attributes. In an attempt to bridge the gap between Lynch’s cognitive mapping tools and sensorial studies, this paper explores smell-walking as a method of cognitive mapping in the context of Cairo. Through a designed smell walk experiment, 25 participants documented their immediate sensations, past experiences, and memories evoked by the smells of Syrian food practices in an open market situated at the edge of El-Rehab, a gated community on the outskirts of Cairo. This pilot study is a step forward in renewing The image of the city by displaying a smell map, participants’ cognitive image, smellscape, and placemaking narratives. It concludes with the collective cognitive perception of a hybrid smellscape that triggers hunger, happiness, and nostalgia.
Spatialising intersectionality: An approach to public space design in self-built neighbourhoods in Cali, Colombia

Published: January 2025

Abstract
Standardisation, scarce spaces of encounter, and neglecting social identities when designing public spaces largely contribute to social discontent in neighbourhood upgrading processes. While discussions on intersectionality are mushrooming in urban studies, there is still a gap in understanding how this approach can be applied to public space design in self-built neighbourhoods, which are also the prevalent form of urbanisation globally. In this context, urban designers need to embrace new frames to address this challenge. Using the case of El Filo Park in Cali, Colombia, we devised a methodological strategy to deploy an intersectional approach within a highly contested public space. Our proposal transcends the intra-group categories by emphasising territory as an inter-group category. We argue that by adopting a multilayered qualitative approach, complex dynamics shaping these spaces are uncovered and the spatial implications of interlocking systems of oppression and privilege faced by individuals and groups with diverse social identities are revealed.
Mercury wet deposition in the urban and industrialised region of Campinas, south-east Brazil
Authors: Hechavarria-Hernandez Amauris , Viana José Lucas Martins , Fostier Anne Hélène 
Published: January 2025

Environmental context Wet deposition is a primary mechanism for transferring atmospheric mercury (Hg) to Earth’s surface. In Brazil, as well as in the rest of the Southern Hemisphere, only limited data on wet Hg deposition are available. This article addresses this gap by providing a comprehensive dataset from nearly 2 years of monitoring, focusing on mercury concentrations in rainwater and wet Hg deposition in Campinas, one of the largest industrial and populated regions in São Paulo state (south-east Brazil). Rationale Data on mercury (Hg) wet deposition in Brazil, as well as in the rest of the Southern Hemisphere, are sparse. To fill this gap, this study presents a comprehensive dataset from a long-term monitoring effort (nearly 2 years) that focuses on Hg concentrations in rainwater and wet Hg deposition in Campinas, one of Brazil’s largest industrial and populated regions located in São Paulo state (south-east Brazil). Methodology A total of 66 rain events were captured from April 2019 to December 2020 using a manually operated rain collector. The total Hg concentration was determined using Cold Vapour Atomic Fluorescence Spectrometry (CVAFS), and wet Hg deposition was calculated. Results The volume-weighted mean (VWM) Hg concentration ranged from 5.59 to 15.3 ng L−1, with the highest value recorded during the driest season; the overall average for the sampling period was 6.42 ng L−1. Annual Hg wet deposition varied from 6.5 to 7.1 µg m−2 year−1. Discussion These results indicate a clear seasonal variation in Hg deposition and suggest that precipitation depth is the primary influencing factor at our study site. Both the VWM and Hg deposition levels were comparable to those observed in many urban and industrial sites in the Northern Hemisphere. More long-term wet deposition monitoring is needed in urban and industrialised areas of the Southern Hemisphere to improve our understanding of the impacts of human activities on the Hg cycle.
A model for the redshift-space galaxy 4-point correlation function
Authors: Ortolá Leonard William , Slepian Zachary , Hou Jiamin 
Published: January 2025

Abstract
The field of cosmology is entering an epoch of unparalleled wealth of observational data
thanks to galaxy surveys such as DESI, Euclid, and Roman. Therefore, it is essential to have a
firm theoretical basis that allows the effective analysis of the data. With this purpose, we
compute the nonlinear, gravitationally-induced connected galaxy 4-point correlation function
(4PCF) at the tree level in Standard Perturbation Theory (SPT), including redshift-space
distortions (RSD). We begin from the trispectrum and take its inverse Fourier transform into
configuration space, exploiting the isotropic basis functions of [1]. We ultimately
reduce the configuration-space expression to low-dimensional radial integrals of the power
spectrum. This model will enable the use of the BAO feature in the connected 4PCF to sharpen our
constraints on the expansion history of the Universe. It will also offer an additional avenue for
determining the galaxy bias parameters, and thus tighten our cosmological constraints by breaking
degeneracies. Survey geometry can be corrected in the 4PCF, and many systematics are localized,
which is an advantage over data analysis with the trispectrum.
A Bionic Robotic Fish with a Dielectric Elastomer
Authors: Zhang Chenghong 
Published: January 2025

Abstract
Dielectric elastomer actuators (DEAs) are promising enabling devices that can be used in a wide range of robots, artificial muscles and microfluidics. They are characterized by high actuating strain, low cost and noise, and high energy density and efficiency. There are three main challenges for enabling DEs to become actuators: (1) developing suitable and compatible electrode materials; (2) effectively isolating the actuator electrode from the surrounding fluid; and (3) creating a rigid frame that usually requires prestraining of the dielectric layer. The use of robotic fish in water is an important application field of biomimetic soft robots. At present, most underwater robotic fish use spiral propulsion, which has several problems, including propulsion efficiency, position controllability and aquatic organism involvement. To provide solutions, the research and development of underwater robotic fish that imitate the fins and body propulsion of fish and the use of soft underwater robotic fish are in full adoption. This project involves the research and development of a bionic soft underwater robot fish with a software driver, which can imitate swimming via the tail fin and body of a fish, especially with respect to stable swimming propulsion, to successfully develop high-performance soft underwater robot fish. In addition, to imitate the unstable swimming movements of fish, such as turning and sharp acceleration and deceleration, robot fish that use DE drivers with good flexibility and high strain have been researched and developed.
Diffusion with preferential relocation in a confining potential

Published: January 2025

Abstract
We study the relaxation of a diffusive particle confined in an arbitrary external potential and subject to a non-Markovian resetting protocol. With a constant rate r, a previous time τ between the initial time and the present time t is chosen from a given probability distribution

K
(
τ
,
t
)

, and the particle is reset to the position that it occupied at time τ. Depending on the shape of

K
(
τ
,
t
)

, the particle either relaxes toward the Gibbs–Boltzmann distribution or toward a non-trivial stationary distribution that breaks ergodicity and depends on the initial position and the resetting protocol. From a general asymptotic theory, we find that if the kernel

K
(
τ
,
t
)

is sufficiently localized near τ = 0, i.e. mostly the initial part of the trajectory is remembered and revisited, the steady state is non-Gibbs–Boltzmann. Conversely, if

K
(
τ
,
t
)

decays slowly enough or increases with τ, i.e. recent positions are more likely to be revisited, the probability distribution of the particle tends toward the Gibbs–Boltzmann state at large times. In the latter case, however, the temporal approach to the stationary state is generally anomalously slow, following for instance an inverse power law or a stretched exponential, if

K
(
τ
,
t
)

is not too strongly peaked at the current time t. These findings are verified by the analysis of several exactly solvable cases and by numerical simulations.
Monolithic U-shaped crystal design for TOF-DOI detectors: a flat top versus a tapered top
Authors: Kiyokawa Miho , Kang Han Gyu , Yamaya Taiga 
Published: January 2025

Abstract
For brain-dedicated positron emission tomography (PET) scanners, depth-of-interaction (DOI) information is essential to achieve uniform spatial resolution across the field-of-view (FOV) by minimizing parallax error. Time-of-flight (TOF) information can enhance the image quality. In this study, we proposed a novel monolithic U-shaped crystal design that had a tapered geometry to achieve good coincidence timing resolution (CTR) and DOI resolution simultaneously. We compared a novel tapered U-shaped crystal design with a conventional flat-top geometry for PET detectors. Each crystal had outer dimensions of 5.85 × 2.75 × 15 mm3, with a 0.2 mm central gap forming physically isolated bottom surfaces (2.85 × 2.75 mm2). The novel U-shape crystal design with a tapered top roof resulted in the best CTR of 201 ± 3 ps, and DOI resolution of 3.1 ± 0.6 mm, which were better than flat top geometry. In the next study, we plan to optimize the crystal surface treatment and reflector to further improve the CTR and DOI resolution.

Published: January 2025

Abstract
Von Neumann bottleneck necessitates the creation of dedicated processors for neuromorphic artificial intelligence tasks such as in-memory computing, where memristors are formulated as synapses. Perovskites are great candidates for memristors owing to their mixed ionic–electronic conduction and their compatibility with cost-effective processing techniques. In this work, we have fabricated a highly stable, lead-free, and flexible perovskite memristors by e-beam evaporation of hot-pressed zero-dimensional (0D) Cs3Bi2I9 pellets. These memristors exhibit reproducible bipolar resistive switching with low operating voltages of −0.18 V and 0.26 V, an excellent ON/OFF ratio (>105), and high endurance (>104 cycles). They were air-stable for more than 30d and were repeatedly tested under high humidity (>80%) atmospheric conditions without encapsulation. The resistive switching in these devices persists even under applied mechanical stress up to a bending radius of 5 mm. A 4 × 4 crossbar array of these Cs3Bi2I9 memristors has been fabricated, which gave a device yield of 81%. Furthermore, their potential for use as artificial synapses has been demonstrated by obtaining critical neuromorphic characteristics such as spike duration dependent plasticity, paired pulse facilitation, and long-term plasticity. This work also shows that 0D Cs3Bi2I9 memristors have the potential to mimic biological synaptic functions of learning and forgetting, which may be useful in realizing flexible and low-power neuromorphic circuits in the near future.
Women’s and Men’s Work in the Transition from Early Modern to Modern Society
Authors: Ågren Maria 
Published: January 2025

Abstract
This chapter situates the question—how did the division of work between men and women change in the transition from early modern to modern society?—within a larger research field. It argues that methodological consistency is essential for a study that bridges the traditional but somewhat arbitrary divide between these two periods. It makes the case that the transition to modernity—understood as the late nineteenth century—should be studied both ‘backwards’, from the point of view of modern society, and ‘forwards’, from the point of view of early modern society. It demonstrates the fruitfulness of studying work as practice, of including both paid and unpaid work, and of using court records as source. It discusses the role of marriage and the marital partnership in the past and contrasts the two-supporter model against the male-breadwinner model.

Abstract
This chapter introduces the mid-Swedish local society in focus: the city of Västerås, west of Stockholm on Lake Mälaren, and the neighbouring rural districts of Snevringe and Tuhundra, all in the county of Västmanland. It identifies some of the major processes characterizing the 160 years covered in the book: population growth and proletarianization, enclosures, liberalization of the economy, improved infrastructure, and transition from an estate-based to a diversified class society. It identifies Västerås as a hub for trade and distribution of raw materials, especially iron and grain between Bergslagen and Stockholm. It describes the organization of hamlets, villages, and towns, and provides population data. In Västmanland, as in the country as a whole, the population comprised more women than men throughout the study period. In 1760, there were 82 men to 100 women; in 1880, the gap was reduced to 91 men to 100 women.
