AbstractThird-dose coronavirus disease 2019 vaccines are being deployed widely but their efficacy has not been assessed adequately in vulnerable older people who exhibit suboptimal responses after primary vaccination series. This observational study, which was carried out by the VIVALDI study based in England, looked at spike-specific immune responses in 341 staff and residents in long-term care facilities who received an mRNA vaccine following dual primary series vaccination with BNT162b2 or ChAdOx1. Third-dose vaccination strongly increased antibody responses with preferential relative enhancement in older people and was required to elicit neutralization of Omicron. Cellular immune responses were also enhanced with strong cross-reactive recognition of Omicron. However, antibody titers fell 21–78% within 100 d after vaccine and 27% of participants developed a breakthrough Omicron infection. These findings reveal strong immunogenicity of a third vaccine in one of the most vulnerable population groups and endorse an approach for widespread delivery across this population. Ongoing assessment will be required to determine the stability of immune protection.

Authors: Edwards-Gaither Lesley , Harris Ovetta , Perry Valencia 
Published: January 2023

Purpose:
The purpose of this article is to outline the challenges and opportunities faced by speech-language pathologists (SLPs) providing telepractice services as the profession approaches the 100th anniversary of the American Speech-Language-Hearing Association in 2025. As this anniversary approaches, SLPs nationwide will reflect on the profession's past, present, and future. Undoubtedly, issues concerning the COVID-19 pandemic and the use of telepractice technology during this time will be analyzed. This article will outline several challenges for the profession and clinicians to consider for the longevity of telepractice service delivery, including (a) consensus on eHelper/facilitator terminology, (b) designating a telepractice service delivery model, (c) exploring telepractice occupational culture, and (d) pursuing future directions (e.g., ethnographic applications and cultural-linguistic diversity).

Conclusions:
Although telepractice service delivery has existed for less than a century, there is evidence of rapid progress. Meeting the challenges ahead for SLPs using telepractice may have a lasting impact on clinical implications in the field of speech-language pathology in 2025 and beyond the COVID-19 pandemic.
A natural commutation current topology of hybrid HVDC circuit breaker integrated with limiting fault current
Authors: Zhang Xiong , Zhuo Chaoran , Yang Xu 
Published: January 2023

AbstractThe high‐voltage direct current (HVDC) power transmission short‐circuit fault protection is a big challenge, and it is the main obstacle to promote the HVDC multi‐terminal networks. A natural commutation current topology (NCCT) of hybrid HVDC circuit breaker (DCCB) integrated with limiting fault current is proposed in this paper, which shares several obvious merits, such as lower peak fault current, shorter fault isolation time and low turn‐off loss. The main contributions in this paper are made as follows. (1). A second‐order RLC circuit in novel NCCT circuit breaker is utilized as the current limiting circuit to dramatically reduce the fault current rising slope and its peak value. (2) A asynchronous NCCT circuit breaker has been investigated to broaden the proposed NCCT circuit breaker's optimal working area. (3) By taking China Zhangbei 500 kV four‐terminal DC grid as an example, an optimization design technique of the asynchronous NCCT‐DCCB is developed to demonstrate the process of the theoretical analysis and parameter design. The correctness of the proposed NCCT‐DCCB and the feasibility of the optimization design technique are confirmed by EMT simulation on PSCAD/EMTDC and hardware‐in‐loop experiment on PLECS‐RtBox.

Context. The 21 cm hydrogen line is arguably one of the most powerful probes with which to explore the Universe, from recombination to the present times. To recover it, it is essential to separate the cosmological signal from the much stronger foreground contributions at radio frequencies. The Baryon Acoustic Oscillations from Integrated Neutral Gas Observations (BINGO) radio telescope is designed to measure the 21 cm line and detect baryon acoustic oscillations (BAOs) using the intensity mapping (IM) technique.
Aims. This work analyses the performance of the Generalized Needlet Internal Linear Combination (GNILC) method when combined with a power spectrum debiasing procedure. This method was applied to a simulated BINGO mission, building upon previous work from the collaboration. It compares two different synchrotron emission models and different instrumental configurations and takes into account ancillary data in order to optimize both the removal of foreground emission and the recovery of the 21 cm signal across the full BINGO frequency band and to determine an optimal number of frequency (redshift) bands for the signal recovery.
Methods. We produced foreground emission maps using the Planck Sky Model (PSM) and generated cosmological HI emission maps using the Full-Sky Log-normal Astro-Fields simulation Kit (FLASK) package. We also created thermal noise maps according to the instrumental setup. We apply the GNILC method to the simulated sky maps to separate the HI plus thermal noise contribution and, through a debiasing procedure, recover an estimate of the noiseless 21 cm power spectrum.
Results. We find a near-optimal reconstruction of the HI signal using an 80-bin configuration, which resulted in a power-spectrum reconstruction average error over all frequencies of 3%. Furthermore, our tests show that GNILC is robust against different synchrotron emission models. Finally, adding an extra channel with C-Band All-Sky Survey (CBASS) foregrounds information, we reduced the estimation error of the 21 cm signal.
Conclusions. The optimization of our previous work, producing a configuration with an optimal number of channels for binning the data, significantly impacts decisions regarding BINGO hardware configuration before commissioning. We were able to recover the HI signal with good efficiency in the harmonic space, but have yet to investigate the effect of 1/f noise in the data, which will possibly impact the recovery of the HI signal. This issue will be addressed in forthcoming work.

Simuler les propriétés des verres et fontes vitreuses est un besoin fondamental pour résoudre différents problèmes scientifiques et industriels, mais aussi pour mieux décrire le phénomène de la transition vitreuse dont la compréhension complète nous échappe.
Parmi les méthodes de prédiction des propriétés des matériaux, les simulations par dynamique moléculaire (classique ou ab initio) apportent une masse de connaissances importantes et permettent de mieux comprendre la formation et les propriétés des verres. L’apprentissage machine permet maintenant d’épauler ces simulations et aussi de valoriser de nombreuses mesures expérimentales existantes. Il offre ainsi de nouveaux horizons pour la compréhension et l’utilisation du verre dans de multiples domaines, de l’industrie à la volcanologie.

Published: January 2023

We demonstrate low temperature deposition conditions for vanadium dioxide (VO2) phase change material by pulsed laser deposition, which are compatible with III–V semiconductors heterostructures typically used in optoelectronic applications. The characterizations of the VO2 coated thin films grown on GaAs show a 50% change in optical reflectivity in the mid-infrared range and a variation of electric conductivity of two orders of magnitude between the insulating (low temperature) and the metallic (high temperature) states. The transition temperature is estimated around 68 °C (341 K). We also study the functionalization of mid-infrared quantum cascade lasers (QCLs) (operating at wavelengths λ ∼ 7–8 μm) with VO2 layers, in view of engineering the laser emission properties with an integrated VO2 layer. We demonstrate QCLs that integrate a VO2 layer on the surface that interacts with the guided laser mode. A maximum operating temperature of 61 °C (334 K) has been measured.
Compartmental modelling in epidemic diseases: a comparison between SIR model with constant and time-dependent parameters
Authors: Sikder Arun Kumar , Hossain Md Biplob , Islam Md Hamidul 
Published: January 2023

Abstract
The compartmental modelling is one of the most widely used techniques in investigating the dynamics of infectious diseases. This modelling technique usually treats model parameters as constant. However, the parameters associated with infectious diseases randomly change following the changes in the conditions of disease transmission. As a result, the estimated parameters are often found over or under-determined by direct problems when some conditions change and the forecasting using direct problems often goes wrong. In this study, we estimate the model parameters over different time intervals by means of the inverse problem method and then solve the forward problem using these estimated parameters to compare them with the real epidemic data. We apply the method to estimate the parameters corresponding to Nipah virus, Measles and COVID-19 in the context of Bangladesh. The results suggest that the method helps to gain improved insights into epidemic scenarios corresponding to smaller time intervals. The results of the direct problem are found to fall apart fairly quickly from the real epidemic data as the length of the interval used in the inverse problem method increased.
Mobile impurities interacting with a few one-dimensional lattice bosons
Authors: Yordanov Vasil R , Isaule Felipe 
Published: January 2023

Abstract
We report a comprehensive study of the ground-state properties of one and two bosonic impurities immersed in small one-dimensional optical lattices loaded with a few interacting bosons. We model the system with a two-component Bose–Hubbard model and solve the problem numerically by means of the exact diagonalization method. We report binding energies of one and two impurities across the superfluid (SF) to Mott-insulator transition and confirm the formation of two-body bound states of impurities induced by repulsive interactions. In particular, we found that an insulator bath induces tightly bound di-impurity dimers, whereas a SF bath induces shallower bound states.

Abstract
To enhance the performance of transition metal chalcogenide composite electrode material, a key point is a composite design and preparation based on the synergistic effect between the oxide and selenide materials. With a facile ‘one step template-annealing’ step, Ni3Se4, Ni0.6Zn0.4O and ZnO are simultaneously synthesized, by 500 °C annealing. With the increase of annealing temperature from 350 °C to 600 °C, nickel selenides change from NiSe2 to Ni3Se4 to NiSe. The charge storage capacity increases first and then decreases with the increase of annealing temperature, and the 500 °C annealing obtained three compound composite Ni3Se4/Ni0.6Zn0.4O/ZnO (NNZ-500) nanoparticle material displayed a high specific capacitance of 1089.2 F g−1 at 1 A g−1, and excellent cycle stability of 99.8% capacitance retention after 2000 cycles at 5 A g−1. Moreover, an asymmetric supercapacitor was assembled with NNZ-500 as the positive electrode material and activated carbon as the negative electrode material. This kind of asymmetric supercapacitor demonstrated a high energy density of 53.4 Wh kg−1 at 819.0 W kg−1, and cycle stability with 98.6% capacitance retention after 2000 cycles. This material preparation approach provides great potential for the future development of high performance transition metal composite electrode materials in energy storage applications.
Electron and ion acceleration from femtosecond laser-plasma peeler scheme
Authors: Shen X F , Pukhov A , Qiao B 
Published: January 2023

Abstract
Using three-dimensional particle-in-cell simulations, we further investigate the electron and ion acceleration from femtosecond laser–plasma peeler scheme which was proposed in our recent paper (Shen et al 2021 Phys. Rev. X 11 041002). In addition to the standard setup where a laser pulse impinges on an edge of a single tape target, two new variants of the target, i.e. a parallel tape and a cross tape target, were proposed, where strong surface plasma waves can also be efficiently excited at the front edges of the target. By using a tabletop 200 TW-class laser pulse, we observe generation of high-flux, well-collimated, superponderomotive electrons. More importantly, quasimonoenergetic proton beams can always be obtained in all the three setups, while with the single tape case, the obtained proton beam has the highest peak energy and narrowest spectrum.

and OH molecules. It is found that He atoms get excited at the very early stage, as a result of ionization wave formation. This process follows by excitation of O, N2 and N

always overtakes He excitation by about 5 ns, with rotational temperature peaking at about 650 K and decaying afterwards, whereas rotational temperature of N2 always remains constant equal to about 300 K. This value is associated with gas kinetic temperature since the electron-rotational (e-R) excitation process is too slow, so it cannot be activated during the plasma phase and no additional change in rotational excitation of N2 happens. Nitrogen molecules remain vibrationally excited in the discharge, post-discharge and jet areas after the plasma pulse which is likely a result of ionization wave propagation. Upon water vapor injection the apparent OH rotational distributions reveal double Boltzmann slope representing thermalized and non-thermalized OH groups. Rotational temperature of the thermalized group correlates with the one of N

showing, however, much longer relaxation time, whereas for the non-thermalized group it remains above 1 eV at all conditions. The obtained results confirm that the studied ns- discharge is a good candidate for temperature-sensitive applications, such as the bio-sample treatment. Further analysis related to the ionization waves, electron density and electric field behavior is undertaken in the second part.
Analysis of Tsunami Traveling Ionospheric Disturbances Due to Tsunami Using The GNSS-TEC Method

Published: January 2023

Abstract
The Global Navigation Satellite System (GNSS) is a navigation satellite system that provides information on the position and speed of 3D objects on the earth’s surface. GNSS is increasingly being used in the field of survey and mapping work because of its high measurement accuracy, and its use can be done anywhere and anytime. The working principle of GNSS is to transmit digital data from satellites to receivers on the earth’s surface. The digital data is carried by a carrier microwave called the L-band. In the propagation path, the carrier microwave will pass through the ionosphere and troposphere. The collection of electrons contained in the ionosphere layer and the wet & dry components in the troposphere can disrupt the wave propagation path to be slower. This slow propagation will cause the accuracy of the results obtained during the measurement to be more inaccurate. The delayed wave data can obtain the Total Electron Content (TEC) value in the ionosphere layer. TEC is a value that represents the electron density in 1m2 in the ionosphere. The vertical movement of the land surface and seawater can suddenly cause acoustic waves that propagate towards the ionosphere layer, which causes the electron density to decompose. These disorders are known as Traveling Ionospheric Disturbances (TID). In this study, we studied the characteristics of the change in electron density in the ionosphere caused by the tsunami. The tsunami observed was a tsunami in the territory of Indonesia due to the eruption of Mount Tonga on January 15, 2022. The change in electron density was calculated from the significant difference in the TEC value during the tsunami propagation time. The calculation of the change in the TEC value is called the TEC reduction. TEC reduction is obtained by calculating the TEC value, calculated with the reference value of the polynomial curve. The result of the TEC reduction, which has a change in value at the same time as the tsunami is coming, is most likely the TID of the tsunami.
Sentinel-1 SAR Polarization Combinations for Flood Inundation Spatial Distribution Mapping (Case Study: South Kalimantan)
Authors: Adiba A , Bioresita F 
Published: January 2023

Abstract
41.98% of disaster events occurred in 2021 in Indonesia were flood disasters. Rain of 2.08 billion m3 during the second week of January 2021 occurred in South Kalimantan, Indonesia, where the volume of rainwater was not proportional to the capacity of the Barito Watershed. It caused flooding in 11 cities/regencies. In the discourse of flood disaster mitigation, it is important to be able to map the flood inundation spatial distribution. Research with remote sensing methods, especially active remote sensing, which can penetrate clouds and free from weather disturbances can be an option in analysing flood inundation distribution. Sentinel-1 is one of the active remote sensing with Synthetic Aperture Radar (SAR) C-band imaging mission which is being widely used for flood disaster analysis. Generally, research on flooding is carried out using only VV or VH polarization. Only some researches use combination of both polarizations. Therefore, in this paper, combinations of those two polarizations are used in order to explore the use polarization combination in mapping the distribution of flood inundation, especially for case studies of flood disasters in South Kalimantan. However, in this study case, VV and VH polarization combination are not suitable in mapping flood inundation. VH polarization only showed best result in mapping flood inundation with overall accuracy of 89%, while VV and VH polarization combination resulted overall accuracy of 73%.
