Authors: Langford Vaughan S , Perkins Mark J 
Published: January 2025

Selected ion flow tube mass spectrometry (SIFT-MS) is a chromatography-free, direct-analysis technique that is ideally suited to real-time, quantitative analysis of volatile compounds in air at trace concentrations. SIFT-MS utilises highly controlled, soft chemical ionisation – in the form of gas-phase ion–molecule reactions – coupled with mass spectrometry detection to provide both broad-spectrum and specific analysis of volatiles with diverse functionalities.
This book provides readers with a broad understanding of the principles of the SIFT-MS technique and how it differs from conventional chromatographic approaches that are used for analysis of volatiles. It will also aid users to identify existing and new methods where adoption of SIFT-MS would be advantageous, e.g. through reduction in sample preparation or higher throughput, and provides the knowledge and insight required to develop best-practice methods and effectively evaluate the data that they generate and approaches to optimising, validating, and transferring methods to routine analysis and other applications.
This book addresses two needs for SIFT-MS users:
The audience for this book is method developers and laboratory technicians engaged in routine analysis and research laboratories, but it is also well suited to graduate students, reducing the mentoring load for academics and research fellows.

Authors: Zhang Wei , Zhang Maosheng , Sun Xiaoyan , Mo Jingyi 
Published: January 2025

AbstractThe reconstruction of three‐dimensional (3D) audio systems is essential for enhancing immersive experiences and advancing film and television technology. However, the 22.2 multichannel 3D playback system requires precise speaker arrangement and a specific playback environment, and its computational demands hinder its widespread adoption. This paper addresses these challenges by calculating the ideal 22.2 system sound signal based on the actual playback environment and developing a neural network model for speaker signal allocation using a sound signal dataset. Trained with TensorFlow, the model determines the allocation weights for each speaker, optimizing signal distribution. Experimental comparisons show that our model reduces the mean square error and computation time by 25.27%, significantly improving computational efficiency and error performance over the original system, thereby facilitating the efficient reconstruction of 3D audio for diverse playback environments.

Photocatalytic Strategies for the Synthesis of Xanthates and Their Analogues
Authors: Prieto Alexis , Geniller Lilian , Taillefer Marc , Jaroschik Florian 
Published: January 2025

AbstractSulfur-containing organic molecules, particularly xanthates (dithiocarbonates) and dithiocarbamates, are valuable intermediates in synthetic chemistry and the development of bioactive molecules. For instance, xanthates are potent carbon-radical precursors that can be engaged in diverse transformations, including the 1,2-difunctionalization of alkenes and other functionalizations. However, traditional synthetic methods for these compounds have been limited in efficiency and diversity. This Short Review focuses on novel photochemical procedures for generating xanthates and dithiocarbamates, discussing their advantages and disadvantages. Two main strategies emerge from the literature: (1) Three-component reactions involving the in situ formation of carbodithioate anions, and (2) two-component reactions (direct xanthylation and thiocarbamoylthiolation) using ex situ prepared xanthate and dithiocarbamate sources.1	Introduction2	Three-Component Transformations3	Two-Component Transformations4	Miscellaneous5	Conclusion

Published: January 2025

AbstractIn recent years, the incidence of neurodegenerative diseases, including Alzheimerʼs disease, Parkinsonʼs disease, Huntingtonʼs disease, and amyotrophic lateral sclerosis, has exhibited a steadily rising trend, which has posed a major challenge to the global public health. Traditional Chinese medicine, with its multicomponent and multitarget characteristics, offers a promising approach to treating neurodegenerative diseases. However, comprehensively elucidating the complex mechanisms underlying traditional Chinese medicine formulations remains challenging. As an emerging systems biology method, network pharmacology has provided a vital tool for revealing the multitarget mechanisms of traditional Chinese medicine through high-throughput technologies, molecular docking, and network analysis. This paper reviews the advancements in the application of network pharmacology in treating neurodegenerative diseases using traditional Chinese medicine, analyzes the current status of
relevant databases and technological methods, discusses the limitations, and proposes future directions to promote the modernization of traditional Chinese medicine and the development of precision medicine.

Published: January 2025

Background The homoeopathic medicine contains various biomolecules/compounds that can be identified through several modern instruments. Computational screening is one of the most common methods used for predicting these drug compound interactions with target protein/ligand molecules of microbial structure to formulate drug design.
Objective This study aimed to explore the biological compounds present in Myristica sebifera 30C and predict its physical interaction with Staphylococcus aureus proteins through the molecular docking method.
Materials and Methods An analysis of the phytoconstituents of Myristica sebifera 30C was performed using the Agilent 1290 Infinity LC system coupled to Agilent 6545 Accurate Mass Quadrupole Time-of-Flight (QTOF) with Agilent Jet Stream thermal gradient technology followed by a detailed docking study. The two phytoconstituents of Myristica sebifera 30C having more than 80% score were docked against two target proteins of S. aureus, namely, PDB:3U2D and PDB:1T2P, and their binding potential was measured. The ligand with the lower glide docking score is considered to have the best binding affinity.
Results Myristica sebifera 30C contains 21 compounds and mainly 1H-indole-3-ethanamine, N-methyl, and (2R,3S,4S)-4-(1,3-benzodioxol-5-yl)-4-(3,4-dimethoxyphenyl)-2,3-dimethylbutan-1-ol as bioactive components of the drug. It also contains (2R,3S,4S)-4-(1,3-benzodioxol-5-yl)-4-(3,4-dimethoxyphenyl)-2,3-dimethylbutan-1-o1, which has a lower glide score of –9.29 kcal/mol against the target protein PDB:3U2D, considered the best binding affinity. The amino acids involved in interaction between two biomolecules are ILEB:86, PROB:87, ILEB:51, ILEB:175, LEUB:103, and VALB:79.
Conclusion Based on the outcomes of the computational molecular docking analysis, it was concluded that bioactive substances found in Myristica sebifera 30C exhibit significant binding against DNA gyrase protein (PDB:3U2D) and Sortase A (PDB:1T2P) of S. aureus, which suggests that these substances may act as a promising antimicrobial agent.

Abstract
Background Variability in the prescription of antibiotics constitutes an area for improvement related to patient safety issues, including the risk of infection and health care efficiency based on evidence.
Objectives The study aims to evaluate the effect of an intervention to reduce the duration of antibiotic treatment in complicated appendicitis.
Methods A quality improvement program was implemented in the surgical department of The Cuban Hospital (Doha, Qatar). During a 3-month baseline period, data about antibiotic duration, consumption (daily defined doses), and cost (in Qatary Riyals) were identified, as well as during two plan-do-study-act (PDSA) intervention periods. Interventions include action focused on staff education, monitoring antibiotic use, feedback, and reminders during discharge planning.
Results At baseline, 13 patients with complicated appendicitis were documented, while there were 41 and 15 patients during PDSA cycles 1 and 2, respectively. A 29.5% reduction in days of antibiotic treatment was observed during the PDSA cycle 2 in comparison with the baseline. Accordingly, a reduction of 38.7% in the consumption of antibiotics and a reduction of 24.6% in cost were observed, with no adverse outcomes for patients during the 30-day follow-up period.
Conclusion The intervention resulted in an improvement in antibiotic use with satisfactory patient outcomes and an additional effect on the efficiency of health care and the prevention of microbial resistance and other adverse effects.
Towards a Development and Development Studies of Liberation
Authors: Plaatjie Sebeka Richard 
Published: January 2025

AbstractPoverty and inequality between and within nations, migration, racism, xenophobia, pandemics, and climate change are some of the more pressing challenges that threaten human existence. These challenges have motivated many scholars within development studies to call for the reconfiguration of the field. Particularly, since the pandemic, increasingly vibrant debates within leading development studies journals have hosted debates about the future of development studies. This paper contributes to the debate on reimaging post-pandemic development studies, arguing for foregrounding ‘ethics’ as an analytical category within the field, towards what can be described as a development study of liberation.

This research aims to explore the decoration of TiO2 substrates with silver nanoparticles as a means of enhancing the photocatalytic oxidation of organic compounds. The results show that decorated TiO2 substrates exhibit significantly higher photocatalytic activity in sunlight than undecorated substrates. Morphological analysis is performed, followed by optical and structural characterizations. Scanning electron microscopy analysis of the TiO2 reveals many nanotubular structures with particle sizes of ∼134.4, 148.8, and 132.7 nm at random locations. TiO2 is also found to have an absorbance range of 397.6 nm, from which it is known that the photocatalyst reacts in the presence of an ultraviolet source. From the Miller indices of the x-ray diffraction peaks, the preferred crystal orientation is found to be associated with a face-centered cubic structure with a crystallite size of 3.76 nm. Using these promising results, photocatalytic analysis is performed, revealing good degradation characteristics. This investigation reveals that TiO2 substrates coated with Ag nanoparticles possess significant potential for application in the photocatalytic oxidation of methylene blue dye, which is a crucial step toward establishing a cleaner environment.

Background Partner notification is an important step in the control of sexually transmissible infections (STIs). STIs remain at high rates among young people and can have serious reproductive consequences if left untreated. This study aimed to determine the preferences and motivations for partner notification among young people in Australia. Methods Quantitative and free-text qualitative data were collected through the 2024 Sex, Drugs and Rock ‘n’ Roll survey, an annual cross-sectional survey conducted among people aged 15–29 years old in Victoria, Australia. Respondents were recruited using convenience sampling through social media advertisements. Counts and proportions were calculated for the preferences and motivations for partner notification by regular and casual sexual partners as well as methods of communication. Inductive content analysis was used to analyse free-text responses. Results The partner notification module of the survey was completed by 1163 people (60.3% identified as women, 40.2% as heterosexual) who provided a total of 1720 free-text responses. The majority, 1056 (90.8%) stated that they would notify their sexual partners and 1142 (98.2%) would want to be notified by a sexual partner of an STI risk. Qualitative analysis highlighted that respondents felt that partner notification is the responsible thing to do to look after their own and their partner’s health and protect others by reducing transmission. Few stated that embarrassment and fear of repercussions may make them less likely to notify their partners or that it would depend on the type of relationship. Most preferred to notify regular partners face-to-face (941, 80.9%) and casual partners via text message (785, 67.5%). Conclusion Almost all young people want to notify and be notified by partners of an STI risk regardless of age, gender or sexual identity. Tailoring resources by communication method and partner type is one way in which practitioners and public health authorities can support young people in undertaking this important step in STI control.

Published: January 2025

Abstract
Gravitational interactions were studied by measuring the influence of small external field masses on a microwave resonator. It consisted of two spherical mirrors, which acted as independent pendulums individually suspended by strings. Two identical field masses were moved along the axis of the resonator symmetrically and periodically between a near and a far position. Their gravitational interaction altered the distance between the mirrors, changing the resonance frequency, which was measured and found consistent with Newton’s law of gravity. The acceleration of a single mirror caused by the two field masses at the closest position varied from

Timing advanced receiver autonomous integrity monitoring augmented by BDSBAS
Authors: Xue Yu , Zheng Fu , Deng Liangcheng , Lin Yuanhui , Shi Chuang 
Published: January 2025

Abstract
Global navigation satellite system (GNSS) provides sufficiently accurate and affordable time and frequency information for timing and synchronization (T&S) equipment, which is widely used in modern infrastructures such as 5 G, small cells, and data centers. However, ensuring the integrity of GNSS timing service faces challenges due to the inherent vulnerability of GNSS signals and the complexity of user environments. Advanced receiver autonomous integrity monitoring (ARAIM) provides integrity monitoring of GNSS services at the user side, while BeiDou satellite-based augmentation systems (BDSBAS) improves GNSS service integrity from the service side by broadcasting corrections and integrity information. This study explores the potential of integrating ARAIM with dual-frequency multi-constellation (DFMC) BDSBAS for the integrity monitoring of GNSS timing services, as both technologies use DFMC signals and complement each other at different service levels. Several key improvements are made to the ARAIM algorithm, including risk allocation, solution estimation, and protection level (PL) calculation, to enable its application in the integrity monitoring of timing services. The improved algorithm, referred to as the timing ARAIM (T-ARAIM) algorithm, provides a quality control solution for high-precision timing applications. Furthermore, the T-ARAIM algorithm is enhanced by incorporating the correction and integrity parameters from DFMC BDSBAS messages, further improving the accuracy and reliability of timing services. The performance of the T-ARAIM algorithm augmented by BDSBAS is thoroughly validated and analyzed through simulation experiments, real-world experiments, and BDSBAS augmentation experiments. Simulation results indicate that when the receiver antenna position is estimated, the coverage of T-ARAIM (availability greater than 99.9%) using GPS + BDS-3 reaches 37.2%, with further improvement to 54.3% upon fixing the inter-satellite bias (ISB). In scenarios where the receiver antenna position is fixed, T-ARAIM coverage can achieve 100% even with a single constellation. Real-world experiments utilizing raw observations from seven globally distributed GNSS stations reveal that fixing the receiver antenna position reduces timing errors and time protection levels (TPL) by over 40%. Fixing the ISB does not affect the accuracy of the timing solution but slightly reduces TPL by about 2 ns. Fixing the receiver antenna position and/or ISB increases observation redundancy, significantly improving T-ARAIM availability. The integration of BDSBAS augmentation information further improves the timing solution, with timing accuracy increasing by approximately 4.4%–5.8% and T-ARAIM availability rising by about 11.7%–13.4% when the receiver antenna position is estimated. In fixed-position scenarios, the improvements in timing accuracy are more pronounced, approximately 20.0% to 28.5%, with T-ARAIM availability reaching 100%.

Authors: Li Hanyang , Song Yeshuai , Wang Jianwei , Dou Xinyu 
Published: January 2025

Abstract
In this paper, we present a underwater object angular measurement method that is composed of a novel fluid pressure sensor and a algorithm for angle measurement. The innovative pressure sensing structure, incorporating four fiber Bragg gratings, demonstrates remarkable sensitivity to fluid pressure, achieving a resolution of 1.3 pm μϵ
−1 . Based on this unique structure, we have developed an algorithm that utilize the characteristics of Bragg grating signal to determine the angular position of the vibration source. Through several different experiments, we evaluated the performance of pressure sensor and accuracy of angular algorithm. The results indicated that our algorithm achieves a mean absolute error of 2.3 degrees, coupled with a root mean square error of 3.1 degrees, demonstrating its high precision in determining the angular position of the vibration source. Furthermore, the practicality and robustness of this method has been validated in complex flow fields, demonstrating its promising application in underwater environment monitoring.
A non-isothermal phase-field crystal model with lattice expansion: analysis and benchmarks
Authors: Punke Maik , Salvalaglio Marco , Voigt Axel , Wise Steven M 
Published: January 2025

Abstract
We introduce a non-isothermal phase-field crystal model including heat flux and thermal expansion of the crystal lattice. The fundamental thermodynamic relation between internal energy and entropy, as well as entropy production, is derived analytically and further verified by numerical benchmark simulations. Furthermore, we examine how the different model parameters control density and temperature evolution during dendritic solidification through extensive parameter studies. Finally, we extend our framework to the modeling of open systems considering external mass and heat fluxes. This work sets the ground for a comprehensive mesoscale model of non-isothermal solidification including thermal expansion within an entropy-producing framework, and provides a benchmark for further meso- to macroscopic modeling of solidification.
Asymmetric hysteresis characteristics of magnetorheological elastomer embedding the tilt chain-like structure on the translational shear test: experiment and modeling
Authors: Lin Dezhao , Gong Di , Yang Fan , Li Ruihong , Zhang Weiqiang 
Published: January 2025

Abstract
The magnetorheological elastomer (MRE) with tilt chain-like structure can significantly enhance the magnetorheological effect, but its hysteresis nonlinearity in the stress–strain responses is still unclear, especially the effect of the chain-like structure angle, which is essential for effective designs of controllable MRE-based devices. In this study, the hysteresis characteristics of the tilt chain-like structure MRE in the stress–strain curve of the translational shear test are investigated through the experiment and modeling. The experimental results of shear testing indicated that the stress–strain relationships of MRE with the tilt chain-like structure show an asymmetric hysteresis loop together with an obvious offset, which is different from the isotropic MRE and anisotropic MRE with the symmetric chain-like structure. In order to describe the asymmetric hysteresis loop in the translational shear characteristic, a stop operator-based modified Prandtl–Ishlinskii (PI) model is established considering a hyperbolic-tangent envelope function. The comparisons between model-predicted and measured data demonstrate that the established modified PI model can accurately describe the asymmetric hysteresis loops of MRE with different chain-like structure angles for wide ranges of excitation conditions and magnetic fields.
Quantum Field Theory of black hole perturbations with backreaction. Part III. Spherically symmetric 2nd order Maxwell sector
Authors: Neuser J. , Thiemann T. 
Published: January 2025

Abstract
In this paper we extend reduced phase space approach to black hole perturbation theory to
Maxwell matter. We expand the resulting reduced Hamiltonian to second order in the graviton and
photon perturbations and find that the corresponding equations of motion match the ones derived in
the literature. Accordingly our approach reproduces previous results at second order. Its real
virtue lies in the fact that it extends to any order in perturbation theory in a manifestly gauge
invariant fashion, includes backreaction effects and covers the black hole interior due to
working in the regular Painlevé Gullstrand gauge.
