Patient-centered care and interprofessional collaboration in medical resident education: Where we stand and where we need to go
Authors: Gantayet-Mathur Arpita , Chan Karenn , Kalluri Meena 
Published: June 2022

AbstractPatient centered care (PCC) and interprofessional collaboration (IPC) remain important goals for all healthcare systems. While these tenets are a cornerstone of training for nursing and allied health professionals (AHPs), their role in internal medicine resident (IMR) training is unstructured and limited. We performed a narrative review to answer two questions, firstly ‘what is known about the attitudes and behaviors of internal medicine (IM) physicians and trainees with respect to PCC and IPC and how does this compare to AHPs?’ and secondly, ‘what evidence based interventions have been trialed to promote PCC and IPC in medical training?’ We searched databases including Cochrane, Medline, Embase, CINAHL and MedPortal. We reviewed 102 publications and found that medical residents tend to value PCC less than non-physician trainees. Hierarchical professional attitudes and a poor understanding of AHP roles are barriers to IPC, whereas diminished time for direct patient care, neglect of the patient’s context and social determinants of health, and lack of self-reflection are barriers to PCC. Published educational interventions for IMRs and AHPs have included classroom sessions, structured ward- and clinic-based interprofessional (IP) work, post-discharge care, home visits, and reflective practice. Interventions were evaluated using questionnaires/surveys, focus groups, tests, primary outcome assessments and ethnographic analysis. The most promising interventions are those that allow learners time for multidisciplinary observation, holistic patient assessments, engagement in care transitions and reflective practice. Based on the review findings we have made recommendations for integration of IPC and PCC training into IMR curricula. Future educational interventions should allow IMR observerships in a multidisciplinary team, introduce residents to the patient’s environment through home visits, incorporate patient/family perspectives in care, and include narrative reflections as part of professional development. Based on our findings and recommendations, these experiences can provide IMRs with much-needed exposure to collaborative, patient-centric care early in postgraduate training.

Published: June 2022

Objectives
Hearing loss has been the most common sensory impairment and one of the most challenging disabilities in the elderly population, with a multitude of consequences for the quality of life and psychosocial well-being. The present work was a narrative review on the effectiveness of communicative/psychosocial interventions that were designed for the elderly with hearing impairment.

Methods
A search of the academic database identified relevant articles based upon seven search facets (“quality of life,” “psychological,” “psychosocial wellbeing,” “hearing impaired,” “deaf,” “elderly”) up to November 2019. Inclusion criteria concerned the combined following terms: “quality of life,” “psychological” and “psychosocial wellbeing,” with the terms “hearing impaired” “deaf,” “elderly” and “interventions” and their possible variations.

Results
Only 9 out of 950 identified studies explicitly focused on psychosocial wellness and/or quality of life. Outcomes were sometimes contradictory in terms of the efficacy in quality of life and psychological wellbeing improvements.

Conclusion
Findings were promising in terms of quality of life improvement but did not allow for definitive conclusions, since study populations were heterogeneous and primary outcome measures did not always focus on deafness. Future research is needed to define effective protocols and evaluation measures that will be able to enlighten benefits in terms of psychosocial wellness and quality of life in the hearing impaired elderly population.
Detection of gravitational waves using parametric resonance in Bose–Einstein condensates
Authors: Robbins Matthew P G , Afshordi Niayesh , Jamison Alan O , Mann Robert B 
Published: June 2022

Abstract
An interesting proposal for detecting gravitational waves involves quantum metrology of Bose–Einstein condensates (BECs). We consider a forced modulation of the speed of sound of a BEC, whose modulation frequency matches that of an incoming continuous gravitational wave. The speed of sound modulation induces parametric resonance in the BEC, which in turn enhances sensitivity of the BEC to gravitational waves. We find that such a BEC detector could potentially be used to detect gravitational waves across several orders of magnitude in frequency, with the sensitivity depending on the speed of sound, size of the condensate, and frequency of the phonons. We discuss the sensitivity of a possible BEC experiment and comment on the current technological limitations. We also comment on the noise sources as well as what is necessary for such a detector to become feasible.
Absence of the Higuchi bound in a family of alternative linear massive spin-2 models
Authors: Fortes Hemily G M , Alves Márcio E S 
Published: June 2022

Abstract
There is a well known result from the Fierz–Pauli (FP) theory in de Sitter background, it is the existence of a lower bound for the mass m of the spin 2 particle, the Higuchi bound. It establishes that m

In this sense, m should be unacceptable high in order to fulfill this condition at the time of the inflationary epoch of the Universe, posing a difficulty to conciliate the FP theory with cosmology. In this article we show that the Higuchi bound can be circumvented in an alternative description of massive spin-2 particles known as

models. In maximally symmetric spaces the theory has two free parameters which can be consistently chosen in order to make the model absent of a lower bound for m. Then, m can be arbitrarily smaller than the energy scale of inflation avoiding instabilities at that time.
Singly heavy baryons in nuclear matter from an SU(3) chiral soliton model
Authors: Won Ho-Yeon , Yakhshiev Ulugbek , Kim Hyun-Chul 
Published: June 2022

Abstract
We investigate how the masses of singly heavy baryons undergo changes in nuclear matter, based on a medium-modified SU(3) chiral soliton model. Having explained the bulk properties of nuclear matter, we discuss the masses of singly heavy baryons in nuclear matter. We generalize the vector-meson Lagrangian including the heavy-meson soliton interaction. The mass spectrum of singly heavy baryons are obtained with the effects of explicit SU(3) symmetry breaking considered as a perturbation. The results show that the mass of the singly heavy baryon in a nuclear medium is rather sensitive to the medium modifications of the heavy meson mass.
Occupational doses in interventional angiography after radiological protection training and use of a real-time direct display dosimeter
Authors: Lundvall Lise-Lott , Sandborg Michael 
Published: June 2022

Abstract
Vascular x-ray guided interventions are complex and may result in high occupational doses to ionising radiation if staff do not take appropriate actions to minimise their exposure. In this prospective intervention study, ten staff members wore an extra personal dosimeter on the upper body above their regular protective clothing during four consecutive periods. Between each period either additional practical radiological protection training was given or a real-time direct display dosimeter were provided to the staff. Each staff’s personal dose equivalent, Hp(10) normalised to the total air kerma-area product for the procedures where each staff were involved, KAPt, was used as the dependent variable. A focus-group interview with the staff were performed about the usefulness of the training and real-time dose rate display system. Our aim was to investigate if the interventions (practical training or real-time dose rate display) did affect the staff doses in the short and long term (five months later). Significant (p < 0.05) reductions of staff doses Hp(10)/KAPt were found after practical radiological protection training, but not after using real-time dose rate displays. Significant reductions were maintained after five months without additional interventions. The results from the focus-group interview indicated that making radiation ‘visible’, during practical training and usage of real-time direct display dosimeter, made it easier to understand how to act to lower occupational doses.
A dynamic interference suppression method with the optimal payoff of proximity radar based on a game model
Authors: Dai Jian , Hao Xinhong , Li Ze , Wang Zhe , Yan Xiaopeng 
Published: June 2022

Abstract
The proximity pulse Doppler radar (PPDR) possesses high-range resolution and has been widely used in short-range detection. Unfortunately, the detection performance is seriously deteriorated by interference. Therefore, a dynamic interference suppression method (DISM) based on a game model is proposed. In the DISM, three interference suppression strategies are proposed for different interference strategies. The first strategy is the deceptive interference suppression strategy via the identity recognition of the PPDR. The second is a barrage interference suppression strategy, which is realized via the recognition of the time-frequency joint features of the target and interference. The last strategy is to combine the previous two strategies. For optimal interference suppression performance, the DISM will dynamically choose an interference suppression strategy according to their payoffs, which effectively enables the PPDR to maintain the dominant position in the game with the interference source. The efficiency of the DISM at different interference and signal-to-interference-plus-noise ratios is proved by comparison with other methods.
Extended tuning of distributed-feedback lasers in a bias-tee circuit via waveform optimization for MHz-rate absorption spectroscopy
Authors: Nair Anil P , Minesi Nicolas Q , Jelloian Christopher , Kuenning Nicholas M , Spearrin R Mitchell 
Published: June 2022

Abstract
Variations in injection-current waveform are examined using diplexed radio-frequency modulation with continuous-wave distributed-feedback (CW-DFB) lasers, with the aim to maximize the spectral tuning range and signal-to-noise ratio for MHz-rate laser absorption spectroscopy (LAS). Utilizing a bias-tee circuit, laser chirp rates are shown to increase by modulating the AC input voltage using square waves instead of sine waves and by scanning the laser below the lasing threshold during the modulation period. The effect of waveform duty cycle and leading-edge ramp rate are further examined. A spectral scan depth on the order of 1 cm−1 at a scan frequency of 1 MHz is achieved with a representative CW-DFB quantum cascade laser near 5 μm. Distortion of high-frequency optical signals due to detector bandwidth is also examined, and limitations are noted for applications with narrow spectral features and low-bandwidth detectors. Based on common detection system limitations, an optimization approach is established for a given detection bandwidth and target spectra. A representative optimization is presented for measurements of sub-atmospheric carbon monoxide spectra with a 200-MHz detection system. The methods are then demonstrated to resolve transient gas properties (pressure and temperature) via LAS at MHz rates in a detonation tube and shock tube facility. An appendix detailing a first-order model of high-speed distributed feedback laser tuning dynamics is also included to support the experimental observations of this work.
Improving cone-beam CT quality using a cycle-residual connection with a dilated convolution-consistent generative adversarial network
Authors: Deng Liwei , Zhang Mingxing , Wang Jing , Huang Sijuan , Yang Xin 
Published: June 2022

Abstract

Objective.Cone-Beam CT (CBCT) often results in severe image artifacts and inaccurate HU values, meaning poor quality CBCT images cannot be directly applied to dose calculation in radiotherapy. To overcome this, we propose a cycle-residual connection with a dilated convolution-consistent generative adversarial network (Cycle-RCDC-GAN). Approach. The cycle-consistent generative adversarial network (Cycle-GAN) was modified using a dilated convolution with different expansion rates to extract richer semantic features from input images. Thirty pelvic patients were used to investigate the effect of synthetic CT (sCT) from CBCT, and 55 head and neck patients were used to explore the generalizability of the model. Three generalizability experiments were performed and compared: the pelvis trained model was applied to the head and neck; the head and neck trained model was applied to the pelvis, and the two datasets were trained together. Main results. The mean absolute error (MAE), the root mean square error (RMSE), peak signal to noise ratio (PSNR), the structural similarity index (SSIM), and spatial nonuniformity (SNU) assessed the quality of the sCT generated from CBCT. Compared with CBCT images, the MAE improved from 28.81 to 18.48, RMSE from 85.66 to 69.50, SNU from 0.34 to 0.30, and PSNR from 31.61 to 33.07, while SSIM improved from 0.981 to 0.989. The sCT objective indicators of Cycle-RCDC-GAN were better than Cycle-GAN’s. The objective metrics for generalizability were also better than Cycle-GAN’s. Significance. Cycle-RCDC-GAN enhances CBCT image quality and has better generalizability than Cycle-GAN, which further promotes the application of CBCT in radiotherapy.

Published: June 2022

Abstract
The concept of near-zero energy conversion from ocean waves is an emerging topic that can be applied to supply power to self-powered applications in sea-crossing bridges. In this paper, a point-absorbing wave energy converter (WEC) with a novel zero-pressure-angle mechanism structure was proposed and investigated. The system includes a wave energy capture module, power take-off module (PTO), generator module, and energy storage module. The proposed PTO structure consists of a pair of guide rods, zero-pressure-angle rockers, gearbox, and flywheel, which convert the oscillation of the buoy into unidirectional continuous rotation of the generator, and electricity is stored in the supercapacitor. For accurate prediction, kinematic and dynamic approaches were employed for the non-constant damping PTO. The mechanical test and sensing system experiments achieved the highest mechanical efficiency of 81.87%, the maximum output power of 5.49 W, and the 53.44% average efficiency. It was found that the PTO with a flywheel can effectively improve the output performance compared to without a flywheel. In addition, the experiments of the actual WEC were performed and recorded an output power ranging from 0.964 W to 3.218 W, proving that the proposed structure meets the power requirements for self-powered sea-crossing bridge applications.

Published: June 2022

Abstract
Along with advancements in superconducting technology, especially in high-temperature superconductors (HTSs), the use of these materials in power system applications is gaining outstanding attention. Due to the lower weight, capability of carrying higher currents, and the lower loss characteristic of HTS cables, compared to conventional counterparts, they are among the most focused large-scale applications of superconductors in power systems and transportation units. In near future, these cables will be installed as key elements not only in power systems but also in cryo-electrified transportation units, that take advantage of both cryogenics and superconducting technology simultaneously, e.g., hydrogen-powered aircraft. Given the sensitivity of the reliable and continuous performance of HTS cables, any failures, caused by faults, could be catastrophic, if they are not designed appropriately. Thus, fault analysis of superconducting cables is crucial for ensuring their safety, reliability, and stability, and also for characterising the behaviour of HTS cables under fault currents at the design stage. Many investigations have been conducted on the fault characterisation and analysis of HTS cables in the last few years. This paper aims to provide a topical review on all of these conducted studies, and will discuss the current challenges of HTS cables and after that current developments of fault behaviour of HTS cables will be presented, and then we will discuss the future trends and future challenges of superconducting cables regarding their fault performance.

Published: June 2022

Abstract
Silicate ceramics are one of the established candidates employed in many industrial and medical applications. Not many of the existing reports mention and investigate the properties of the phases or individual components of these materials. In this exploratory study, one such sodium calcium silicate, combeite (Na2Ca2Si3O9) was synthesized by the solid-state route and studied for its properties. The preliminary investigation involved thermal treatments followed by characterization to identify the formation of the pure phase. The mechanical behaviour was evaluated by compression tests. Surface treatments were executed to enhance the capabilities to support cellular proliferation. The in-vitro acellular immersion test showed the formation of calcium phosphates. All the tested materials exhibited adequate cell viability properties for prospective applications in life sciences.

filters of the short period V1833 Ori eclipsing binary is presented based on new ground-based CCD photometric observations. We analyzed the BVRI photometric light curves of the system, using PHOEBE 0.31a, a binary star modeling program, with the Wilson-Devinney method based on Roche geometry to achieve the best accordance with the photometric observations to determine their absolute parameters from the light curves. We updated the ephemeris of V1833 Ori using two new light curve minima derived by our new observational data from those collected in the literature and analyzed the change of the system’s orbital period. The O–C analysis indicates that the variations of the orbital period of V1833 Ori with time are increasing at a rate of 3.03 × 10−7 days yr−1. The distance of V1833 Ori is 173.7 ± 15.6 pc. From the solutions, we find that V1833 Ori is an A-subtype W UMa overcontact binary with q = 0.701 mass ratio and f = 1.14 fill-out factor. The HR diagram positions of the eclipsing binary system’s components are discussed. The system’s absolute dimensions were compared to those of similar binaries in the

Published: June 2022

Abstract
The optimized superconducting stellarator Wendelstein 7-X (W7-X) is equipped with an island divertor for energy control and efficient pumping. We investigated the performance of the island divertor in terms of gas exhaust. For this purpose we have installed 18 pressure gauges in the vacuum vessel. This allowed us to determine the exhaust efficiency, the leakage, the collection efficiency and the compression ratio of the island divertor. These quantities depended strongly on the magnetic configuration. The best performance was obtained in the high-iota configuration. The exhaust efficiency was 2.9%, significantly higher than in the standard configuration (0.44%), and the maximum neutral compression was about 80. The high-iota configuration appears particularly promising for long-pulse operation of W7-X.
Research on the Effect of Vibration Mixing Intensity on the Solidification Efficiency and Properties of Concrete
Authors: Li Rantao 
Published: June 2022

Abstract
In order to further improve the efficiency of concrete in engineering application, the influence of vibration mixing intensity on the solidification efficiency and performance of concrete is studied. Four vibration intensity levels of 0g, 2g, 3g and 4g were selected to explore the initial and final solidification time and working performance of concrete under different vibration intensity. The test results show that when the vibration strength is 2g, 3g and 4g, the initial solidification time decreases by 4.9%, 7.5% and 8.7%, the final solidification time decreases by 1.5%, 1.9% and 2.7%, and the slump increases by 3.9%, 5.9% and 15.7%, respectively, compared with the vibration strength of 0g. Compared with 0g vibration strength, the compressive strength of concrete with 4g vibration strength is increased by 5.48%, 4.11% and 7.04% respectively at the age of 3D, 7d and 28d. The results show that with the increase of vibration intensity, the initial solidification time and final solidification time shorten, the slump increases, the compressive strength increases. Vibration mixing is of great significance to the application and expansion of concrete engineering.
Research on the Design of Guide Wall of Diaphragm Wall doubled as Retaining Wall in Deep Foundation Pit
Authors: Kang Yale , Zhang Xiaofeng , Liu Xin 
Published: June 2022

Abstract
It was repeated in the traditional design and construction process of the retaining wall and guide wall of diaphragm wall, resulting in prolonged construction period, increased the amount of temporary structural concrete pouring and demolition, and caused data waste and environmental pollution, which does not meet the requirements of green construction. In this paper, based on the deep foundation pit project of the standard underground station of rail transit, the structural form of the guide wall of diaphragm wall is reformed by coordinating the construction sequence of guide wall and retaining wall. The traditional scheme is optimized by calculating the stress on guide wall, which was doubled as a retaining wall. It reduces the dosage of concrete of guide wall and retaining wall engineering 18.16%. Further, we systematically evaluated in the economic and social benefits of the guide wall doubled as a retaining wall in this paper. The results show that the optimized scheme has perfect design function and safe and reliable structure. Compared with the traditional scheme, the optimized scheme can reduce the total cost of related projects by about 24.36% and shorten construction period. The research in this paper has significant engineering economic value and social benefit, which can provide reference for the design and construction of similar projects.
