Published: August 2024

Hydrogen peroxide (H2O2) transport by aquaporins (AQP) is a critical feature for cellular redox signaling. However, the H2O2 permeation mechanism through these channels remains poorly understood. Through functional assays, two Plasma membrane Intrinsic Protein (PIP) AQP from Medicago truncatula, MtPIP2;2 and MtPIP2;3 have been identified as pH-gated channels capable of facilitating the permeation of both water (H2O) and H2O2. Employing a combination of unbiased and enhanced sampling molecular dynamics simulations, we investigated the key barriers and translocation mechanisms governing H2O2 permeation through these AQP in both open and closed conformational states. Our findings reveal that both H2O and H2O2 encounter their primary permeation barrier within the selectivity filter (SF) region of MtPIP2;3. In addition to the SF barrier, a second energetic barrier at the NPA (asparagine-proline-alanine) region that is more restrictive for the passage of H2O2 than for H2O, was found. This behavior can be attributed to a dissimilar geometric arrangement and hydrogen bonding profile between both molecules in this area. Collectively, these findings suggest mechanistic heterogeneity in H2O and H2O2 permeation through PIPs.

Published: August 2024

We previously reported pulmonary arterial remodelling and active endothelial-to-mesenchymal transition (EndMT) in smokers and patients with early chronic obstructive pulmonary disease (COPD). In the present study, we aimed to evaluate the role of different drivers of EndMT. Immunohistochemical staining for EndMT drivers, TGF-β1, pSMAD-2/3, SMAD-7, and β-catenin, was performed on lung resections from 46 subjects. Twelve were non-smoker-controls (NC), six normal lung function smokers (NLFS), nine patients with small-airway diseases (SAD), nine mild-moderate COPD-current smokers (COPD-CS) and ten COPD-ex-smokers (COPD-ES). Histopathological measurements were done using Image ProPlus softwarev7.0. We observed lower levels of total TGF-β1 (P<0.05) in all smoking groups than in the non-smoking control (NC). Across arterial sizes, smoking groups exhibited significantly higher (P<0.05) total and individual layer pSMAD-2/3 and SMAD-7 than in the NC group. The ratio of SAMD-7 to pSMAD-2/3 was higher in COPD patients compared with NC. Total β-catenin expression was significantly higher in smoking groups across arterial sizes (P<0.05), except for COPD-ES and NLFS groups in small and medium arteries, respectively. Increased total β-catenin was positively correlated with total S100A4 in small and medium arteries (r = 0.35, 0.50; P=0.02, 0.01, respectively), with Vimentin in medium arteries (r = 0.42, P=0.07), and with arterial thickness of medium and large arteries (r = 0.34, 0.41, P=0.02, 0.01, respectively). This is the first study uncovering active endothelial SMAD pathway independent of TGF-β1 in smokers, SAD, and COPD patients. Increased expression of β-catenin indicates its potential interaction with SMAD pathway, warranting further research to identify the deviation of this classical pathway.
Maternal high-fat diet regulates offspring hepatic ABCG5 expression and cholesterol metabolism via the gut microbiota and its derived butyrate

Published: August 2024

Maternal high-fat diet intake has profound effects on the long-term health of offspring, predisposing them to a higher susceptibility to obesity and metabolic dysfunction-associated steatotic liver disease. However, the detailed mechanisms underlying the role of a maternal high-fat diet in hepatic lipid accumulation in offspring, especially at the weaning age, remain largely unclear. In this study, female C57BL/6J mice were randomly assigned to either a high-fat diet or a control diet, and lipid metabolism parameters were assessed in male offspring at weaning. Gut microbiota analysis and targeted metabolomics of short-chain fatty acids (SCFAs) in these offspring were further performed. Both in vivo and in vitro studies were conducted to explore the role of butyrate in hepatic cholesterol excretion in the liver and HepG2 cells. Our results showed that maternal high-fat feeding led to obesity and dyslipidemia, and exacerbated hepatic lipid accumulation in the livers of offspring at weaning. We observed significant decreases in the abundance of the Firmicutes phylum and the Allobaculum genus, known as producers of SCFAs, particularly butyrate, in the offspring of dams fed a high-fat diet. Additionally, maternal high-fat diet feeding markedly decreased serum butyrate levels and down-regulated ATP-binding cassette transporters G5 (ABCG5) in the liver, accompanied by decreased phosphorylated AMP-activated protein kinase (AMPK) and histone deacetylase 5 (HADC5) expressions. Subsequent in vitro studies revealed that butyrate could induce ABCG5 activation and alleviate lipid accumulation via the AMPK-pHDAC5 pathway in HepG2 cells. Moreover, knockdown of HDAC5 up-regulated ABCG5 expression and promoted cholesterol excretion in HepG2 cells. In conclusion, our study provides novel insights into how maternal high-fat diet feeding inhibits hepatic cholesterol excretion and down-regulates ABCG5 through the butyrate-AMPK-pHDAC5 pathway in offspring at weaning.
Optimal eco‐emission scheduling of the reconfigurable solar farm‐based combined hydrogen, heat, and power (RSF‐CHHP)
Authors: Baghaei Ali , Olamaei Javad , Nasiri Mohammad Reza
Published: August 2024

Combined hydrogen, heat, and power (CHHP) is the cogeneration unit simultaneously meeting hydrogen, heat, and power demands. Due to the low efficiency of the electrolyser, the main grid or other generation units supply its input power. Herein, the photovoltaic farm's (PV farm) output power is used as the input power of the electrolyser. Optimal economic and emission scheduling of CHHP‐based microgrid (CHHP_MG) is defined as an objective function. To improve system efficiency, the scheduling problem is done in two cases, reconfigured SP‐PV farm and conventional SP‐PV farm. To optimal management of both demand and generation sides, a time of use (TOU) based demand response program is employed in the proposed short‐term study. To have a comprehensive study, the optimum solar panel tilt angle is calculated, and its impacts on the main function are analysed. Multi‐objective genetic algorithm is used to solve optimization problems. By solving the objective function, the obtained values for profit and pollution amount are 620$ and 69,245.78 gr, respectively. By applying the load response program, the mentioned values are changed to 715.132$ and 6872.5 gr. Since the input power is supplied through solar panels, the placement angle of the panels is very important and with the optimal setting of the placement angle, the values change to 780$ and 6825.3 gr.
Robust predictive control strategy for grid‐connected inverters with ultra‐local model based on linear matrix inequality
Authors: Liu Chunxi , Hong Fangrui , Liu Zhile , Zhou Li , Jin Xuanxu , Lin Zhiwei
Published: August 2024

To address the issue of poor robustness in the model predictive control of grid‐connected inverters due to disturbances in load model parameters, this article developed an ultra‐local model robust predictive controller based on Linear Matrix Inequality (LMI). First, to avoid dependence on model parameters, an ultra‐local model of the system was constructed. Second, in the process of setting the state variable compensation gain, to simplify the complex computational steps of the traditional Lyapunov algorithm, the task of finding the gain that satisfies the Lyapunov stability condition was ingeniously transformed into an optimization problem of solving constrained LMI. Third, the optimized state variables are utilized to design a new cost function predictive model, thereby enhancing the precision of system control. Finally, the effectiveness of the proposed approach has been validated through simulations and experiments.
Multi-transition study of methanol towards NGC 1068 with ALMA
Authors: Huang K.-Y. , Abbink D. , Viti S. , García-Burillo S.
Published: August 2024

Context. The outflowing molecular gas in the circumnuclear disc (CND) of the nearby (D = 14 Mpc) AGN-starburst composite galaxy NGC 1068 is considered as a manifestation of ongoing AGN feedback. The large spread of velocities from the outflowing gas is likely driving various kinds of shock chemistry across the CND.

Aims. We performed a multiline molecular study using CH3OH with the aim of characterizing the gas properties probed by CH3OH in the CND of NGC 1068 and investigating its potential association with molecular shocks.

Methods. Multi-transition CH3OH were imaged at the resolution of 0.″5 − 0.″8 with the Atacama Large Millimeter/submillimeter Array (ALMA). We performed a non-LTE radiative transfer analysis coupled with a Bayesian inference process in order to determine the gas properties such as the gas volume density and the gas kinetic temperature.

Results. The gas densities traced by CH3OH point to ∼106 cm–3 across all the CND regions. The gas kinetic temperature cannot be well constrained in any of the CND regions, though the inferred temperature is likely low (≲100 K).

Conclusions. The low gas temperature traced by CH3OH suggests shocks and subsequent fast cooling as the origin of the observed gas-phase CH3OH abundance. We also note that the E-/A-isomer column-density ratio inferred is fairly close to unity, which is, interestingly, different from the Galactic measurements in the literature. It remains inconclusive whether CH3OH exclusively traces slow and non-dissociative shocks, or whether the CH3OH abundance can actually be boosted in both fast and slow shocks.
X-ray occultations in active galactic nuclei: Physical properties of eclipsing clouds as part of the broad-line region cloud ensemble
Authors: Pietrini P. , Torricelli-Ciamponi G. , Risaliti G.
Published: August 2024

Context. Short-term X-ray variability in active galactic nuclei (AGNs) can be explained as being due to varying X-ray absorption induced by the temporary occultation of the primary X-ray source, when moving absorbing clouds cross the line of sight to the X-ray source itself. Earlier work suggests that these absorbing clouds have physical properties similar to those of broad-line region (BLR) emitting clouds and are located in the same spatial region.

Aims. We intend to extract physical information on each individual absorber associated with any given occultation event detected in our sample and to analyse general properties of the cloud ensemble whose components can produce X-ray eclipses.

Methods. From the analysis of previously detected occultation events, two ‘observables’ characterising each single occultation event can be derived: the peak fractional hardness ratio variation (ΔHR/HR) and the duration of the event normalised by a characteristic eclipse timescale evaluated for each AGN source. To determine the eclipsing cloud properties, we devised a procedure a) based on simplifying assumptions on the geometry of both the X-ray source and the cloud-like gas condensations, and on the cloud X-ray absorbing properties in the energy range of interest (2–10 keV), and b) relying on a set of simulated instrumental responses from both XMM and Suzaku relevant instruments to different incoming X-ray spectra, absorbed with varying absorber column density and maximum covering factor during the occultation. Thus, we derived information on the individual cloud producing any given occultation event, determining the cloud radius normalised to that of the X-ray source, the spatial location of the cloud, and an estimate of the cloud gas number density for reasonable values of the equivalent absorber column density.

Results. The physical properties of eclipsing clouds that we obtained are consistent with those of BLR clouds. We can exclude the dominance, in the ensemble cloud size distribution, of clouds larger than about 10–12 times the Schwarzschild radius characterising each AGN, and we do not find any significant dependence of the cloud physical size on the distance from the central black hole, in agreement with the results of our previous work. As for the number density of these gas condensations, with our procedure we obtained values within a range of ∼109 − 1011 cm−3, which is consistent with the estimates derived from broad emission line analysis.
Radiation mechanism of twin kilohertz quasi-periodic oscillations in neutron star low-mass X-ray binaries
Authors: Shi Chang-Sheng , Zhang Guo-Bao , Zhang Shuang-Nan , Li Xiang-Dong
Published: August 2024

Context. The connection between quasi-periodic oscillations (QPOs) and magnetic fields has been investigated in various celestial bodies. Magnetohydrodynamic (MHD) waves have been employed to explain the simultaneous upper and lower kilohertz (kHz) QPOs. Nevertheless, the intricate and undefined formation pathways of twin kHz QPOs present a compelling avenue for exploration. This study area holds great interest as it provides an opportunity for deriving crucial parameters related to compact stars.

Aims. We strive to develop a self-consistent model elucidating the radiation mechanism of twin kHz QPOs, which we then compare it with observations.

Methods. A sample of 28 twin kHz QPOs detected from the X-ray binary 4U 1636–53 was used for a comparison with the results of the Markov chain Monte Carlo calculations based on our model of the radiation mechanism of twin kHz QPOs, which is related to twin MHD waves.

Results. We obtained 28 groups of parameters of 4U 1636–53 and a tight exponential fit between the flux and the temperature of seed photons to Compton up-scattering and find that the electron temperature in the corona around the neutron star decreases with increasing seed photon temperature.

Conclusions. The origin of twin kHz QPOs are dual disturbances that arise from twin MHD waves that are generated at the innermost radius of an accretion disc. The seed photons can be transported through a high temperature corona and are Compton up-scattered. The photons that vary the frequencies of twin MHD waves lead to the observed twin kHz QPOs.

Context. Type Ia supernova (SNIa) are excellent probes of local distance and the growing sample sizes of SNIa have driven an increased propensity to study the associated systematic uncertainties and improve standardisation methods in preparation for the next generation of cosmological surveys into the dark energy equation of state, w.

Aims. We aim to probe the potential change in the SNIa standardisation parameter, c, with redshift and the host-galaxy of the supernova. Improving the standardisation of SNIa brightness measurements will require the relationship between the host and the SNIa to be accounted for. In addition, potential shifts in the SNIa standardisation parameters with redshift will cause biases in the recovered cosmology.

Methods. In this work, we assembled a volume-limited sample of 3000 likely SNIa across a redshift range from z = 0.015 to z = 0.36. This sample was fitted with changing mass and redshift bins to determine the relationship between the intrinsic properties of SNe Ia and their redshift and host galaxy parameters. We then investigated the colour-luminosity parameter, β, as a subsequent test of the SNIa standardisation process.

Results. We find that the changing colour distribution of SNe Ia with redshift is driven by dust at a confidence of > 4σ. Additionally, we show a strong correlation between the host galaxy mass and the colour-luminosity coefficient β (> 4σ), even when accounting for the quantity of dust in a host galaxy.

Conclusions. These results indicate that the observed colour distribution of SNe Ia does change with redshift. However, we note that this is an observational effect, rather than an intrinsic change. Future cosmological measurements with SNe Ia must take into account these changing dust distributions to reduce the number of potential sources of systematic uncertainty.
Rotational synchronisation of B-type binaries in 30 Doradus

Published: August 2024

The spin evolution of stars in close binary systems can be strongly affected by tides. We investigate the rotational synchronisation of the stellar components for 69 SB1 systems and 14 SB2 B-type systems in the 30 Doradus region of the Large Magellanic Cloud using observations from the VFTS and BBC surveys. Their orbital periods range from a few to a few hundred days, while estimated primary masses for these systems are in the range ∼5−20 M⊙ with mass ratio ranges of q ∼ 0.03 − 0.5 and q ∼ 0.6 − 1.0 for the SB1 and SB2 systems, respectively. Projected rotational velocities of the stellar components have been compared with their synchronous velocities derived from the orbital periods. We find that effectively all systems with an orbital period of more than 10 days must be asynchronous, whilst all the systems with periods of less than 3 days are likely synchronised. In terms of the stellar fractional radius (r), our results imply that all systems with r < 0.1 are asynchronous, with those having r > 0.2 probably being synchronised. For the apparently synchronised systems, our results are more consistent with synchronisation at the mean orbital angular velocity rather than with that at periastron.

Galaxy evolution depends on the environment in which galaxies are located. The various physical processes (ram-pressure stripping, tidal interactions, etc.) that are able to affect the gas content in galaxies have different efficiencies in different environments. In this work, we examine the gas (atomic HI and molecular H2) content of local galaxies inside and outside clusters, groups, and filaments as well as in isolation using a combination of observational and simulated data. We exploited a catalogue of galaxies in the Virgo cluster (including the surrounding filaments and groups) and compared the data against the predictions of the Galaxy Evolution and Assembly (GAEA) semi-analytic model, which has explicit prescriptions for partitioning the cold gas content in its atomic and molecular phases. We extracted from the model both a mock catalogue that mimics the observational biases and one not tailored to observations in order to study the impact of observational limits on the results and predict trends in regimes not covered by the current observations. The observations and simulated data show that galaxies within filaments exhibit intermediate cold gas content between galaxies in clusters and in isolation. The amount of HI is typically more sensitive to the environment than H2 and low-mass galaxies (log10[M⋆/M⊙]< 10) are typically more affected than their massive (log10[M⋆/M⊙]> 10) counterparts. Considering only model data, we identified two distinct populations among filament galaxies present in similar proportions: those simultaneously lying in groups and isolated galaxies. The former has properties more similar to cluster and group galaxies, and the latter is more similar to those of field galaxies. We therefore did not detect the strong effects of filaments themselves on the gas content of galaxies, and we ascribe the results to the presence of groups in filaments.
Study of spatially confined copper plasma by probe beam deflection technique
Authors: Alnama Koutayba , Ibrahim Ihab. , Sulaiman Nawar
Published: August 2024

In the last decade, laser induced plasma (LIP) has emerged as one of the most promising techniques for various applications. It is now commonly investigated using various expensive techniques. Probe beam deflection (PBD) is an inexpensive technique generally utilized to characterize the shock wave. In this work, the copper laser-induced plasma plume and shock wave are both investigated using PBD technique. The plasma is generated at atmospheric pressure using Nd:YAG laser at a low laser power density (0.8 GW/cm2). The contribution of the plasma plume components to the PBD signal is clarified in space and time. The spatial confinement effect by a metallic disk is also investigated. It approves the physical mechanisms responsible for the deflection signal. As well, the spatial distribution of the weak shock wave velocity is considered.
Benchmarking photovoltaic plant performance: a machine learning model using multi-dimensional neighbouring plants

Published: August 2024

The goal of this study is to monitor the performance of a photovoltaic plant by comparing its power output against others with similar characteristics, referred to as neighbours. The purpose of the 15 neighbours is to have the best reference for the performance of the plant in question, in other words, how the plant under analysis performs compared to the 15 neighbours. A machine learning model based on a feed forward Neural Network was employed to model power production as a function of environmental signals and the sun's position. Here, the data from the neighbours are used to train the model and the data from the plant under analysis are used to evaluate the model and predict the power output. Once the power is predicted, the performance ratio of the plant is calculated. The procedure has been tested and validated at several plants for three different cases and the numerical results highlight how the model is able to identify under/over performing plants. Therefore the developed strategy provides industries a valid tool on the correct functioning of a plant.

The concepts of both column fixation corridor (BCFC) and both column screws (BCS) along with the orthopedic total extraperitoneal approach (O-TEP) are highly innovative approaches in orthopedic surgery. However, the orthopedic literature lacks sufficient studies on these topics, indicating a significant gap. This case report aims to highlight how combining these innovative techniques can facilitate the use of BCFC and BCS in the treatment of acetabular fractures with O-TEP, thereby enhancing the feasibility of endoscopic techniques. Furthermore, we aim to discuss the potential advantages of BCFC and BCS concepts when used in O-TEP.

For this purpose, we present a case of a 74-year-old geriatric patient with a transverse acetabular fracture involving the posterior column. The quadrilateral surface was exposed using the O-TEP approach, and the fracture was reduced using a fully endoscopic approach. The fixation was achieved using BCS and a Magic screw through percutaneous screw placement.

The patient’s clinical condition was followed for at least 13 months. The clinical outcomes demonstrated the effectiveness of combining these innovative techniques in the treatment of acetabular fractures, with satisfactory healing and functional recovery observed.

This case report illustrates that combining BCFC and BCS with the O-TEP approach can facilitate the treatment of acetabular fractures with minimally invasive techniques and enhance the feasibility of endoscopic procedures. These findings suggest potential advantages of using BCFC and BCS concepts in O-TEP, warranting further investigation and study.
Pedagogical Principles in Implementing a Data Visualization Project in an Undergraduate Public Health Informatics Course
Authors: Bautista John Robert
Published: August 2024

Background The Applied Public Health Informatics Competency Model lists “data analysis, visualization, and reporting” as one of the eight competencies when teaching public health informatics. Thus, public health informatics students need to develop knowledge and skills in visualizing public health data. Unfortunately, there is limited work that discusses pedagogical principles that could guide the implementation of pedagogical activities related to data visualization in public health informatics.

Objective This study aimed to introduce, discuss, and reflect on pedagogical principles that were implemented for a data visualization project in an undergraduate public health informatics course.

Methods A reflective teaching approach was used to guide the discussion and reflection on how pedagogical principles were implemented for a data visualization project in an undergraduate public health informatics course. The generic implementation framework (i.e., preimplementation, implementation, and postimplementation) was used to organize the discussion of the course's implementation.

Results Four pedagogical principles were implemented as part of a data visualization project in an undergraduate public health informatics course: scaffolding (i.e., outputs built on top of each other), constructivism (i.e., students apply knowledge and work in teams to create a dashboard), critical consciousness (i.e., embedding social determinants of health (SDOH) in their dashboard), and equity and inclusion (i.e., using a free data visualization software that is easy to use for beginners and is used by public health institutions). Postimplementation reflection revealed areas of improvement, such as enhancing group advising, adding more SDOH variables in the dashboard, and plans for scalability.

Conclusion A data visualization project in an undergraduate public health informatics course could benefit from implementing multiple pedagogical principles. Overall, creating dashboards can be a learning tool to enhance data visualization skills among undergraduate public health informatics students. Dashboards can also emphasize the impact of health disparities and inequities in public health by incorporating the principles of SDOH.
Biocatalytic Dearomatisation Reactions
Authors: Turner Nicholas J. , Gerlach Tabea
Published: August 2024

Biocatalytic dearomatisation offers the advantages of high chemo-, regio- and stereoselectivity over chemical strategies. Mono- and dioxygenases with dearomatising properties are already well-established tools for the synthesis of natural products and beyond. Herein, we review investigations of protein sequence–activity relationships, as well as protein-engineering approaches that have been employed to expand the substrate scope of biocatalysts and achieve product regio- and stereodiversity. Thus, oxidative dearomatising biocatalysts offer an increasingly diverse toolbox for the synthesis of asymmetric, oxidised cyclic scaffolds, as illustrated through selected examples of biocatalytic applications in synthetic routes towards natural products and derivatives thereof. Reductases with dearomatising properties have been less well investigated, so we review recent mechanistic findings which, henceforth, allow for expanding applications of this class of biocatalysts. Additionally, chemoenzymatic strategies have been developed to overcome the limitations of purely biocatalytic or chemical dearomatisation approaches. We highlight examples of those combination strategies for the synthesis of asymmetric privileged motifs.

A simple, efficient, and metal-free method was developed for the synthesis of phosphoroamidates. In essence, a mixture of sodium periodate (NaIO4) and hydroxylamine (NH2OH⸱HCl) was used in stoichiometric amounts to execute the phosphoramidation reaction of aromatic amines and triethyl phosphites at room temperature, in open air. This method offers a practical synthesis route to afford a diverse range of phosphoroamidates via the construction of P − N bonds, with excellent functional group compatibility and good yields under mild conditions.
Image-Guided Ablation for Cholangiocarcinoma: Current Evidence and Future Directions

Published: August 2024

Though the incidence of intrahepatic cholangiocarcinoma (ICC) is rare compared with other malignancies, its prevalence is increasing significantly worldwide. Intrahepatic cholangiocarcinoma is an aggressive tumor, typically presenting at an advanced stage and showing resistance to treatments. The primary cause of mortality is liver failure related to tumor progression with associated parenchymal loss and vascular or biliary compromise. Currently, surgical resection remains the primary curative approach, yet less than 20% of patients are eligible for such treatment, and postoperative rate of recurrence are high. In this context, locoregional therapies such as percutaneous thermal ablation have been shown to be safe and effective for patients with unresectable or recurrent ICCs. This review discusses the clinical application of ablation techniques, as it relates to patient selection and tumor characteristics for the treatment of ICC.
Act your age to engage: field evidence on parent versus brand extension

Published: August 2024

Brand managers have to allocate limited resources between developing new brand extensions and supporting parent brands. We contribute by demonstrating how social media engagement can be optimised by creating a fit between social media language and extensions versus parent brands. This is important given that literature suggests that (a) extensions and parent brands should use the same social media strategy and (b) establishing fit between extensions and parent brands should be the focus of brand managers. This study contributes by analysing over 40,000 tweets made by 26 Google-branded twitter accounts (i.e. @google, @gmail). Results show for brand extension (vs. parent brand) and use of locomotion (vs. assessment) language produce regulatory fit and increase engagement. A 10% increase in locomotive language increased favouriting by 19% and retweeting by 11%. Alternatively, for parent brands, a 10% increase in assessment language increased favouriting by 9% and retweeting by 4%.

Published: August 2024

As an extension to the paper by Breuer et al., Ann. Henri Poincare 22, 3763 (2021), we study the linear statistics for the eigenvalues of the Schrödinger operator with random decaying potential with order O(x−α) (α > 0) at infinity. We first prove similar statements as in Breuer et al., Ann. Henri Poincare 22, 3763 (2021) for the trace of f(H), where f belongs to a class of analytic functions: there exists a critical exponent αc such that the fluctuation of the trace of f(H) converges in probability for α > αc, and satisfies a central limit theorem statement for α ≤ αc, where αc differs depending on f. Furthermore we study the asymptotic behavior of its expectation value.
Modeling ultrafast anharmonic vibrational coupling in gas-phase fluorobenzene molecules

Published: August 2024

In this work, we study the energy flow through anharmonic coupling of vibrational modes after excitation of gas-phase fluorobenzene with a multi-THz pump. We show that to predict the efficiency of anharmonic energy transfer, simple models that only include the anharmonic coupling coefficients and motion of modes at their resonant frequency are not adequate. The full motion of each mode is needed, including the time while the mode is being driven by the pump pulse, because all the frequencies present in the multi-THz pump contribute to the excitation of the non-resonantly excited vibrational modes. Additionally, the model gives us the insight that modes with either A1 or B2 symmetry are more actively involved in anharmonic coupling because these modes have more symmetry-allowed energy transfer pathways.
Properties of near superposition of two squeezed vacuum states
Authors: Othman Anas
Published: August 2024

The near superposition of squeezed vacuum states (NSVS) is investigated in this article. The state appears to be a superposition of a squeezed vacuum state (SVS) and a derivative-squeezed vacuum state. We have shown that NSVS is significantly different from any regular superposition of two SVSs. NSVS, like SVS, displays only even photons, but with different distributions. In some cases, NSVS has no vacuum state. NSVS displays sub-Poissonian statistics for small values of the squeezing parameter. NSVS reveals linear and amplitude-squared squeezing, with amplitude-squared squeezing surpassing SVS in most cases. The minimum uncertainty is explored, and a possible method for generating NSVS is explained. We have discovered that NSVS exhibits a similar behavior for all phase differences except when it equals precisely zero. This phenomenon has been identified and could potentially enable more sensitive measurements.

Large-scale three-dimensional (3D) physical modeling is an important method to study landslide-induced impulse waves. In such models, the test randomness is often quite high, which necessitates systematic exploration of the randomness and error. However, only a few relevant studies have been conducted yet. To this end, this study aims to investigate the randomness and error of large-scale 3D landslide-induced impulse wave experiments and provide solutions to the different sources of error. Based on six repeatability experiments with the large-scale 3D physical model of the Wangjiashan landslide-induced impulse wave in the Baihetan reservoir of the Jinsha River, China, the errors of typical physical parameters are classified into systematic errors, which originate from instrumental factors, experimental design, observer bias, environmental factors, and random errors originating from communication and observation. The allowable error rate of landslide motion in the repeatability experiment is found to be 5%, but the dynamic chain transmission of landslide-induced impulse waves leads to the transmission and accumulation of errors, which causes a gradual increase in the errors of landslide motion, primary wave, propagating wave, and run-up process; and the coefficient of variation increases from approximately 3.8% to 25.0%. To reduce the experimental data error, a low-pass filtering model for removing high-frequency noise and a moving window smoothing model for image frame rate mutation are established, which can decrease the coefficient of variation by nearly 1.3%–4.0%. The corrected particle dynamic map exhibits a continuous and smooth flow field, which basically eliminates the velocity field mutation and discontinuity caused by communication data packet loss. Overall, this study can provide theoretical basis and technical support for large-scale 3D landslide-induced impulse wave experiments.
