AbstractDetergent-induced vesicle interactions, critical for applications including virus inactivation, varies according to the detergent type and membrane composition, but the underlying mechanistic details remain underexplored. Here, we use a lipid mixing assay based on Förster resonance energy transfer (FRET), and single-vesicle characterization approaches to identify that sub-micron-sized vesicles are induced to fuse by the non-ionic detergent Triton-X-100. We demonstrate that the process is a multi-step mechanism, characterized by discrete values of FRET efficiency between membrane-embedded fluorophores, and involves permeabilization, vesicle docking, hemi-fusion and full lipid mixing at sub-solubilizing detergent concentrations. We also dissect the kinetics of vesicle fusion to surface-tethered vesicles using a label-free quartz-crystal microbalance with dissipation monitoring approach, opening a platform for biotechnology applications. The presented strategies provide mechanistic insight into the dynamics of vesicle fusion and have implications for applications including drug delivery and sensor development where transport and manipulation of encapsulated cargo is essential.
Effects of Stimulus Intensity and Sweep Count on the Click- and Chirp-Evoked Auditory Brainstem Response
Authors: Campbell Madeline , Delgado Rafael E. , Ananthakrishnan Saradha , Peitsch Katherine 
Published: September 2024

Purpose:
The auditory brainstem response (ABR) can be elicited by broadband stimuli such as the click and chirp. Differences in the click- and chirp-evoked ABR have been extensively described using subjective analyses. The aim of the current research is to determine if subjectively observed differences between the click- and chirp-evoked ABR are also represented in objective signal-to-noise ratio (SNR) measurements obtained from these responses at different stimulus intensities and sweep counts.

Method:

ABRs were collected using click and chirp stimuli on nine adults with normal hearing sensitivity. Three SNR methods (split-sweep average–based SNR [SSA-SNR],
F
ratio–based single-point [Fsp], and multipoint [Fmp]) were used for the objective analysis of the waveforms at four stimulus intensities (20, 40, 60, and 80 dB nHL) and five sweep counts (100, 200, 300, 400, and 500 sweeps).

Results:
SSA-SNR measurements were statistically stronger for chirp- as compared to click-evoked ABRs. Additionally, chirp/click SSA-SNR, Fsp, and Fmp ratio measurements were consistently greater than 1. The advantage associated with the chirp was most noticeable at moderate stimulus intensities for all three measurements.

Discussion:
The advantages for the chirp observed here could have implications for threshold estimation and screening ABR tests. Furthermore, when stimulus intensity and sweep count were varied, general response trends suggest that the three SNR-based methods performed similarly to each other, as well as to traditionally used subjective measures, suggesting that these techniques have the potential to be used effectively in clinic.

Authors: Lower Casey A. , Gleason Emily G. , Toda Asaki , Srinivas Sindhu K. , Levine Lisa D. , Power Maggie E. , Hamm Rebecca F. 
Published: September 2024

Objective Implementation of standardized protocols for antepartum anemia increases intravenous iron (IVFe) use and improves predelivery hemoglobin (Hb). However, this condition is often overlooked and inadequately treated in postpartum care settings. We aimed to determine if implementation of a standardized protocol for postpartum anemia increases postpartum IVFe use and affects clinical outcomes.
Study Design We performed a prospective cohort study evaluating implementation of a standardized inpatient protocol for postpartum anemia. This protocol, implemented in December 2021, recommends (1) IVFe for postpartum Hb 7.0 to 8.9 g/dL and (2) oral iron for postpartum Hb 9.0 to 9.9 g/dL. We compared all postpartum inpatients at a single site from April 2021 (preimplementation period [PRE]) to April 2022 (postimplementation period [POST]). The primary outcome was any IVFe use. Secondary outcomes included number of IVFe doses, oral iron supplementation at discharge, postpartum complications, and length of stay.
Results A total of 805 patients were included (PRE = 401; POST = 404). Patients in the PRE and POST groups differed in ethnicity (PRE: 8.2% Hispanic vs. POST: 14.9% Hispanic, p = 0.003). IVFe use significantly increased from PRE to POST (PRE: 6.0% vs. POST: 11.1%, p = 0.009) even when controlling for differences between groups (adjusted odds ratio: 2.48, 95% confidence interval: [1.08–5.67]). Patients receiving IVFe in the POST group were more likely to receive the recommended three doses of IVFe compared with patients receiving IVFe in the PRE group (POST: 29% vs. PRE: 4%, p = 0.04). Patients in the POST group had shorter lengths of stay than in the PRE group (POST: 1.69 days vs. PRE: 1.81 days, p < 0.001). There were no significant differences in blood transfusion, oral iron supplementation, or postpartum complications.
Conclusion Implementation of a standardized protocol for postpartum anemia increased IVFe use without increasing length of stay.

Diffusion coefficients preserving long-time correlations: consequences on the Einstein relation and on entanglement in a bosonic Bogoliubov system
Authors: Hamdouni Yamen 
Published: September 2024

Abstract
We analytically derive the diffusion coefficients that drive a system of N coupled harmonic oscillators to an equilibrium state exhibiting persistent correlations. It is shown that the main effect of the latter consists in a renormalization of the natural frequencies and the friction coefficients of the oscillators. We find that the Einstein relation may be satisfied at low temperatures with frequency-dependent effective friction coefficients provided that the physical constraints are fulfilled. We also investigate entanglement evolution in a bipartite bosonic Bogoliubov system initially prepared in a thermal squeezed state. It is found that, in contrast to what one may expect, strong coupling slows down sudden death of the entanglement, and for initially separable states entanglement generation may occur.

Published: September 2024

Abstract
Liquid metals (LMs), due to their excellent stretchability, low resistance, and high thermal conductivity, has become an ideal material for preparing stretchable circuits. 3D printing technology can produce patterns with complex structures with high precision and is suitable for low-cost large-scale production of circuits. However, the high surface tension of liquid metals limits the practical application of 3D printing of LMs. In this work, we proposed a method for preparing a mixed ink based on thermoplastic polyurethane, Cyrene solvent, and LMs, and producing stretchable LMs-based electrodes through 3D printing on a fabric substrate. The stretchable LMs-based electrode prepared by this method shows a wide range of strain response and excellent tensile recovery performance, providing theoretical guidance for the application of LMs electrodes. In addition, the LMs-based heaters showed good Joule thermal response at low voltages, as well as good tensile stability, providing a new strategy for wearable heaters.

Published: September 2024

Abstract
In order to enhance the design efficiency of vortex electromagnetic (EM) wave radar detection systems, a method for generating and controlling vortex EM waves based on amplitude-modulated concentric circular array (CCA) is proposed. This method allows for precise control of the vortex EM waves, ensuring accurate main lobe direction while effectively reducing sidelobes. Based on approximate orthogonal transformation, formulas for calculating the excitation amplitudes of each sub-circular array are derived and the time complexity of this method is negligible compared to search-based algorithms. Extensive simulation experiments are conducted and compared with the results obtained from the genetic algorithm (GA) approach, providing robust evidence of the effectiveness of this method(SLL < -30dB).

Authors: Swamy V S , Pandit R , Yerro A , Sandu C , Castellanos B , Rizzo D , Sebeck K 
Published: September 2024

Abstract
The presence of water in the soil can greatly affect the trafficability of off-roading vehicles, making it difficult to operate. As the water content increases, it can eventually lead to sinkage and immobility. Despite the relevance of this topic in many applications, such as military, agricultural, and earthmoving vehicles, the studies available on tire and moist soil interaction are limited. The numerical modeling of such a system is very challenging because it requires accounting for hydro-mechanical effects, large deformations, non-linear behavior, and complex interactions between the tire and the soil. This work contributes to the understanding of the behavior of moist clay under the influence of traffic loading. In particular, the preliminary results of numeric simulations to study the interaction between moist clay and a passing tire using physics-based techniques are presented. A great emphasis is given to the development of an accurate soil model that can capture the fundamental characteristics of moist clays in saturated conditions.

Experimental and numerical analyses on the modal behaviour of an aluminium alloy sheet
Authors: Moisescu A R , Anghelache G 
Published: September 2024

Abstract
The study of modal behaviour for vehicle body panels represents a field of interest for automotive engineering, having a major influence on automotive comfort, with respect to vehicle noise, vibration and harshness, but also concerning the durability of vehicle body. The investigation of natural frequencies and vibration mode shapes is crucial in the design phase, because essential information can be obtained concerning the behaviour of the components in dynamic conditions. The current paper focuses on the investigation of vibration modes and frequency response function on an aluminium alloy sheet. The aim of the paper is to perform the study of modal behaviour both experimentally and theoretically, through measurements using the impact hammer method and respectively through finite element analysis. The CAD model of the aluminium alloy sheet has been developed in Catia V5 environment in view of elaborating the finite element model, which has been used for investigation of modal behaviour, taking into account the case of free vibrations. Through the modal finite element analysis performed in Ansys Workbench, the natural frequencies of the aluminium alloy sheet, as well as the corresponding mode shapes have been obtained. Experiments have been performed on an aluminium alloy sheet, mounted on an elastic support with low natural frequency. The impact hammer method has been used for obtaining the natural frequencies, through frequency analysis of accelerations measured with two piezoelectric accelerometers mounted on the aluminium alloy sheet. The frequency response function has been computed from the response acceleration measured on the aluminium alloy sheet and the impact force measured using the force transducer of the impact hammer. Virtual instruments have been developed in LabVIEW environment for data acquisition, time domain and frequency analysis, as well as for determining the frequency response function using the measured signals. The natural frequencies obtained from the finite element analyses have been compared to the results of measurements and very good similarities have been ascertained. The experimental investigation of modal behaviour contributed to the validation of the finite element model, but further research is required to investigate the possibilities of improving the modal behaviour of the aluminium alloy sheet.

Abstract
The lubricating oil of an internal combustion engine (i.c.e.) performs several functions having a major contribution to the reliability of the system, implying proper operation during the period of exploitation. Replacing the engine oil ahead reaching the turnover / time corresponding to preventive maintenance it turns out to be sometime an imperative action, with negative implications on operating costs. Any user of today vehicles desire to use the engine performances at full percentage, and for that an important condition becomes the changing of the oil at defined intervals of time/rollover intervals. Thus, it is very important to be aware when to replace because a late change of oil can affect the engine operation and, surely, the performance of the vehicle. Premature oil change influences costs, the environment and is considered a harmful action in terms of the process of depletion of resources. As regards the operating conditions, it is intended that they are similar for all vehicles taken into consideration. It is imperative that the study be carried out by investigating the operation of a single type of engine, with a single type of engine oil, for several vehicles with the same technical characteristics. It is considered that the transport fleets are the concrete source that falls under the already mentioned conditions and a methodology based on the analysis of the 10W30 oil samples used in the MX - 11 330 H2, EURO 6 engines of the DAF vehicles within the fleet of one transport company from Argeş county will be used. The authors of this paper will analyze the following properties of the oil: viscosity, density, flash point, contamination with fuel and water content, these being the most important in illustrating the degree of wear and tear of it. The information about the evolution during the exploitation period of these characteristics is the basis for the elaboration of maintenance strategies considering the three desiderata: the environmental issues, the vehicle’s reliability, and the operating costs of the vehicle.
The Hydrogen Vehicle in the Context of the Sustainable Development of the Green Road Transport System

Published: September 2024

Abstract
The scientific work presents concrete research carried out by the authors to implement some concepts of technical and managerial nature, so that those interested in this field can get acquainted with a certain way of exposing the problems concerning the hydrogen-powered vehicle, in the context of the sustainable development of the ecological road transport system. At the moment, the car whose energy for propulsion is generated by means of hydrogen or hydrogen fuel cells does not enjoy a high popularity among users, due to the very high purchase price (where we have high technology, we also have a price to match - a fuel cell is more expensive than an electric battery), the reluctance of the population to use this type of fuel, defined by the danger of explosions and fires generated by hydrogen, and the lack of hydrogen refueling stations in Romania and in some European countries. The use of alternative fuels in internal combustion piston engines has the advantage of significantly reducing pollution due to combustion products. With regard to the direct use of hydrogen as a fuel in internal combustion piston engines, we can say that it has proved its inefficiency, because the hydrogen injected or sucked directly into the engine cylinders is unstable, produces uncontrolled burns and detonations, and in the liquid state it is very difficult to store, it requires special transport methods, hydrogen tanks must be armored with Kevlar because hydrogen in the event of a car accident can explode. For example, if we use it as a fuel in a diesel engine, hydrogen may not ignite itself because the self-ignition temperature in the cylinders of compression-ignition engines is high (600°C). However, at a normal stoichiometric ratio, hydrogen has a high flame rate, much higher than gasoline. This creates a thermodynamic cycle of the thermal engine almost perfectly, but ideally, let us not forget that in poor mixtures of air-hydrogen the flame propagation speed is considerably reduced. The compression ratio of the engine is of utmost importance because it is finally defining the thermal efficiency of the engine. In the following, we present a technical and managerial study with engineering nuances, through which readers can look and understand the stage of development, place and role of the vehicle propelled by hydrogen fuel cells. Finally, the conclusions and further directions of research and development in the field addressed are presented.

Published: September 2024

Abstract
Twin-field quantum key distribution (TF-QKD) is widely studied since it can surpass the key capacity of repeaterless QKD, whereas electromagnetic interference (EMI) is one of the main challenges in its practical applications. This study is based on the Faraday–Michelson TF-QKD. Analyze the effect of EMI on the rotation angle of the Faraday mirror causing an additional quantum bit error rate (QBER). Moreover, the quantum annealing algorithm (QA) based on quantum tunneling mechanism is applied to the optimization of practical TF-QKD. Mapping the secure key rate of TF-QKD into the evaluation function of QA and the transverse magnetic field is introduced to construct the kinetic energy term, which can realize the quantum tunneling effect. Meanwhile, the QA is improved in terms of chaotic optimization to obtain the dynamic initial value of the algorithm, the design of a perturbation method to skip the locally optimal solution, and the use of suitable temperature and magnetic field decay functions. Optimizing TF-QKD with QA, the standard deviation of QBER fluctuation caused by EMI is reduced to 0.206, the mean square error of the signal-state pulse intensity is only
