Specialized killing across the domains of life by the type VI secretion systems of Pseudomonas aeruginosa
Authors: Colautti Jake , Kelly Steven D. , Whitney John C.
Published: January 2025

Type VI secretion systems (T6SSs) are widespread bacterial protein secretion machines that inject toxic effector proteins into nearby cells, thus facilitating both bacterial competition and virulence. Pseudomonas aeruginosa encodes three evolutionarily distinct T6SSs that each export a unique repertoire of effectors. Owing to its genetic tractability, P. aeruginosa has served as a model organism for molecular studies of the T6SS. However, P. aeruginosa is also an opportunistic pathogen and ubiquitous environmental organism that thrives in a wide range of habitats. Consequently, studies of its T6SSs have provided insight into the role these systems play in the diverse lifestyles of this species. In this review, we discuss recent advances in understanding the regulation and toxin repertoire of each of the three P. aeruginosa T6SSs. We argue that these T6SSs serve distinct physiological functions; whereas one system is a dedicated defensive weapon for interbacterial antagonism, the other two T6SSs appear to function primarily during infection. We find support for this model in examining the signalling pathways that control the expression of each T6SS and co-ordinate the activity of these systems with other P. aeruginosa behaviours. Furthermore, we discuss the effector repertoires of each T6SS and connect the mechanisms by which these effectors kill target cells to the ecological conditions under which their respective systems are activated. Understanding the T6SSs of P. aeruginosa in the context of this organism’s diverse lifestyles will provide insight into the physiological roles these secretion systems play in this remarkably adaptable bacterium.
Reconstruction of three‐dimensional sound field system based on machine learning method
Authors: Zhang Wei , Zhang Maosheng , Sun Xiaoyan , Mo Jingyi
Published: January 2025

The 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.
Acoustic absorption of 3D printed samples at normal incidence and as a duct liner
Authors: Jamois Alexis , Dragna Didier , Zieliński Tomasz G. , Galland Marie-Annick
Published: January 2025

Prediction of the acoustic performance of 3D printed materials is investigated at normal and grazing incidence. A direct numerical (microscopic) simulation that solves the full set of Navier–Stokes equations is used as a reference. It is compared with a macroscopic approach in which the material is represented by an equivalent fluid. The materials have a periodic microstructure, consisting either of a single network of spherical or cubic cavities connected by cylindrical channels or of a double-nested network. The samples are printed using the stereolithography technique and are tested using an impedance tube and a duct test bench. For single network geometries, the results of sound absorption at normal and grazing incidence predicted using the equivalent fluid approach are in good agreement with those obtained by the microscopic approach. Comparisons with impedance tube measurements confirm that both approaches can accurately predict the absorption coefficient of the samples. For the in-duct liner configuration, the transmission loss measurements and predictions show similar evolution with frequency change, despite the discrepancy in amplitude. For the double network geometry, the equivalent fluid approach cannot exactly reproduce the results obtained with the direct numerical simulation. Finally, while the predictions with the microscopic approach provide a good match with the impedance tube measurements, only a poor agreement is obtained using the duct testing bench.
Central limit theorems describing isolation by distance under various forms of power-law dispersal
Authors: Forien Raphaël , Wiederhold Bastian
Published: January 2025

In this paper, we uncover new asymptotic isolation by distance patterns occurring under long-range dispersal of offspring. We extend a recent work of the first author, in which this information was obtained from forwards-in-time dynamics using a novel stochastic partial differential equations approach for spatial $\Lambda$-Fleming-Viot models. The latter were introduced by Barton, Etheridge and V\'eber as a framework to model the evolution of the genetic composition of a spatially structured population. Reproduction takes place through extinction-recolonisation events driven by a Poisson point process. During an event, in certain ball-shaped areas, a parent is sampled and a proportion of the population is replaced. We generalize the previous approach of the first author by allowing the area from which a parent is sampled during events to differ from the area in which offspring are dispersed, and the radii of these regions follow power-law distributions. In particular, while in previous works the motion of ancestral lineages and coalescence behaviour were closely linked, we demonstrate that local and non-local coalescence is possible for ancestral lineages governed by both fractional and standard Laplacians.

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

Sulfur-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.

Authors: Chen Qiang , Chen Guanghui , Wang Qianyan
Published: January 2025

In 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.

Authors: V. Kumaravel , Shaw Niharika , Singh Supriya , Paul Subhrajit , Singh Shishir Kumar
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.

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

Poverty 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.
Influence of localized electron states on the superconductivity of ultrathin films of beryllium
Authors: Tutov V. I. , Semenenko E. E.
Published: January 2025

A wide spectrum of distortions induced in ultrathin beryllium films less than 10 Å thick causes a transition of the system from the state of strong localization completely suppressing the superconductivity (in this case, R□ of the layer assumes values of about 97600 Ω) to a weak localization state coexisting with superconductivity at comparatively high Tc (5 K). The resistance per quadratic area element decreases in this case by more than an order of magnitude. Superconductivity with Tc = 1.7 K is observed under strong localization, when R□ of the layer is 34000 Ω.

Authors: Kaner É. A. , Rodrigues F. Perez
Published: January 2025

The Doppler-shifted acoustic cyclotron resonance and magnetoacoustic resonance in metals with a nonconvex Fermi surface are investigated theoretically for an arbitrary form of the deformation potential. The compensation of deformation and electromagnetic resonance contributions to the absorption and dispersion of the velocity of sound is revealed. It is shown that, in addition to the compensation effect in a magnetoacoustic resonance, a considerable increase in the sound absorption may occur due to the vortex fields.

Copper and sodium point-contacts with a strong anisotropy in the dependence of the spectral noise density SV(eV) on the current direction in the junction are investigated. The asymmetry in the SV(eV) dependence is attributed to the difference in the scattering conditions for nonequilibrium phonons at the faces of the contact.

Authors: Leont’eva A. V. , Marinin G. A. , Prokhorov A. Yu. , Anisimova T. N.
Published: January 2025

The peculiarities of low-frequency internal friction (LFIF) in hydrogen and neon cryocrystals are studied. The anomalous behavior of LFIF in H2 and Ne is observed in contrast to the behavior of Ar at low temperatures. This is apparently due to substantial quantum effects in these crystals.

Two-magnon absorption in a four-sublattice quasi-two-dimensional relativistically noncollinear antiferromagnet
Authors: Alistratov A. L. , Krivoruchko V. N. , Stepanov A. A. , Yablonskii D. A.
Published: January 2025

A quasi-two-dimensional four-sublattice antiferromagnet (AFM) with a relativistically noncollinear structure is considered. Photon-decay channels for two-magnon absorption of a microwave field with different polarizations are classified from the point of view of symmetry. It is shown that new channels of intensive two-magnon absorption, which are absent in a collinear multisublattice or a noncollinear two-sublattice system, appear in such a system. It is also shown that the two-magnon absorption in multisublattice magnets may exhibit van Hove singularities even when the single-particle spectrum is free of them.

Authors: Pokrovskii V. L. , Khveshchenko D. V.
Published: January 2025

The dynamics of isolated vortices in a planar magnet is considered at temperatures above the Kosterlitz–Thouless transition. The spectrum of collective modes is determined in the self-consistent field approximation. The force acting on vortices in an external magnetic field is calculated and the frequency dependence of the dissipated power is established.

Authors: Vekhter B. G. , Kaplan M. D.
Published: January 2025

Results of recent experiments on the measurement of anomalously large low-temperature magnetostriction of TmVO4 are analyzed by using the theory of cooperative Jahn–Teller effect. By generalizing the theory to the case when excited states of Tm3+ and weak elastic stresses in the crystal are taken into consideration, the main peculiarities of striction observed in the field H‖z at T > Tc and the considerable striction observed in the field H‖x are explained.
Induced defect formation in neon cryocrystals under exciton self-trapping
Authors: Savchenko E. V. , Rybalko Yu. I. , Fugol’ I. Ya.
Published: January 2025

Lattice relaxation processes are studied under self-trapping in the atomic states. The emission spectra of single-center self-trapped excitons in pure Ne and in Ne with Ar, Kr, or Xe as impurities are studied. The contributions of self-trapping in a regular lattice and at initial defects are separated. It is found that local deformations appearing around an excited center in a regular Ne lattice under the action of the electron component during exciton self-trapping lead to structural defects which persist even after the annihilation of the excitation.

Authors: Golub A. A. , Grimal’skii O. V.
Published: January 2025

Small normal tunnel junctions in which quantum effects are significant are considered. The mean square value of the charge is calculated by using the Monte Carlo method for the region of intermediate values of the viscosity parameter. It is shown that as the viscosity increases, the difference between the discrete and continuous charge state approximations for the system is shifted to the lower temperature region.

Authors: Freiman Yu. A. , Sumarokov V. V. , Manzhelii V. G. , Popov V. A.
Published: January 2025

The heat capacity of the solid solution Ar–O2 is measured in the temperature interval 1.8−8 K with an oxygen concentration 1 and 2 mol.%. The anomaly observed in the heat capacity is due to coupled spin-rotational degrees of freedom of impurity molecules of oxygen. The spin-rotational spectrum and the impurity contribution to the thermodynamics of O2 molecules in a crystal field are calculated. It is shown that the crystal field acting on O2 molecules in an Ar matrix is a superposition of an octahedral and a weak tetragonal field.

Authors: Verkin B. I. , Palatnik L. S. , Ostrovskaya E. L.
Published: January 2025

The friction coefficients of the high-temperature superconducting ceramic YBa2Cu3O7−δ are studied in the interval of normal loads from 2.5 to 25 N at temperatures between 77 and 293 K. A comparison is made with the friction coefficients of ordinary superconductors and antifriction materials. It is found that in the superconducting state, the HTS of the ceramic YBa2Cu3O7−δ is characterized by a very low friction coefficient (f = 0.02).
Optical transitions in noncollinear antiferrodielectrics. Intensity of dipole transitions
Authors: Petrov É. G.
Published: January 2025

The expressions for magnetic and electric dipole moments of spin-forbidden transitions in a noncollinear antiferrodielectric with narrow exciton bands are derived by taking into account the formation of a spin coat (a nonuniform noncollinear ordered arrangement of spins) around a photoexcited ion. The longwave edge of the optical absorption accompanied by the formation of spin coat is analyzed. It is shown that the multimagnon nature of the optical transition gives rise to the Debye–Waller magnetic factor in this case.
Low-itemperature anomalies in plastic flow of high-purity single crystals of LiF (T = 0.55−4.2 K)
Authors: Kaufmann H.-J. , Lubenets S. V. , Natsik V. D. , Pustovalov V. V. , Fomenko L. S. , Shumilin S. É.
Published: January 2025

Temperature dependences of the critical shear stress and the strain-rate sensitivity of the flow stress are obtained for high-purity LiF at very low temperatures. Thermal insensitivity interval (0.55−2 K) for the above parameters is determined and a considerable temperature dependence of plasticity at higher temperatures is detected, which is typical of thermally activated processes. The threshold temperature decreases slightly with increasing rigidity of the crystal and its prestrain. Basic characteristics of athermal deformation make it possible to attribute it to quantum tunneling of dislocations through Peierls barriers.

Authors: Shablo A. A. , Lukashenko A. V. , Bondarenko S. I. , Batrak A. G.
Published: January 2025

The Josephson effect and quantum dc interference in superconducting ceramics YBa2Cu3O7-x having the superconducting transition temperature of 93 K are investigated experimentally. It is shown that along with the quantum interference observed earlier in multilinked samples of high-Tc superconducting ceramics and ac interference, there also exists a quantum interference in singly coupled samples of superconducting ceramics for direct current, the induction-voltage conversion steepness and the signal-to-noise ratio at 77 K being commensurate with similar characteristics of classical de SQUIDs operating at 4.2 K. It is found from the temperature dependence of the Josephson current in samples of size much larger than the coherence length that weak bonds in ceramics with percolation paths of current are of the S–N–S type.

Authors: Bogachek É. N. , Shekhter R. I.
Published: January 2025

The effect of elastic scattering of current carriers in a point contact on the Shubnikov–de Haas oscillations in a longitudinal magnetic field is studied. It is shown that the scattering-induced isotropism of the electron distribution function increases the contribution of quantum oscillations of the density of states to charge transport. Oscillations with an increased amplitude and a de Haas–van Alphen period are accompanied by a nonmonotonic dependence of the contact resistnce on voltage, having a period ℏH/mc.

The first sound absorption coefficient is obtained by using the kinetic equations for rotons and phonons. The coefficient of second viscosity of He II is calculated at different pressures over a wide temperature range, including the phonon–roton and pure phonon regions, by taking into account the inelastic scattering of phonons by rotons and the dispersion of phonon spectrum. The results of theoretical calculations are compared with the experimental data.

Authors: Bar’yakhtar V. G. , Varyukhin V. N. , Datsko O. I. , Reznikov A. V. , Strongin S. B.
Published: January 2025

The temperature spectra of internal friction and dynamic shear modulus of the systems La1.85Sr0.15CuO4 and YBa2Cu3O7−δ are studied at elastic vibration frequencies 60 kHz and 0.8 Hz in the temperature range 60−300 K. A nonmonotonic variation of the internal friction and dynamic shear modulus is observed near the superconducting transition temperature for the system YBa2Cu3O7−δ. Such a variation is not observed for a system that does not undergo a superconducting transition. A considerable difference in the nature of variation of the dynamic shear modulus in the systems LaSrCuO and YBaCuO is observed with decreasing temperature.
