AbstractChronic thromboembolic pulmonary hypertension is caused by incomplete resolution and organization of thrombi. Blood flow dynamics are involved in thrombus formation; however, only a few studies have reported on pulmonary artery blood flow dynamics in patients with chronic thromboembolic pulmonary hypertension. Furthermore, the effects of treatment interventions on pulmonary artery blood flow dynamics are not fully understood. The aim of the study was to evaluate pulmonary artery blood flow dynamics in patients with chronic thromboembolic pulmonary hypertension before and after pulmonary endarterectomy and balloon pulmonary angioplasty, using computational fluid dynamics. We analyzed patient-specific pulmonary artery models of 10 patients with chronic thromboembolic pulmonary hypertension and three controls using computational fluid dynamics. In patients with chronic thromboembolic pulmonary hypertension, flow velocity and wall shear stress in the pulmonary arteries were significantly decreased, and the oscillatory shear index and blood stagnation volume were significantly increased than in controls. Pulmonary endarterectomy induced redistribution of pulmonary blood flow and improved blood flow dynamics in the pulmonary artery. Balloon pulmonary angioplasty improved pulmonary blood flow disturbance, decreased blood flow stagnation, and increased wall shear stress, leading to vasodilatation of the distal portion of the pulmonary artery following balloon pulmonary angioplasty treatment.

Authors: Shah Manami , Staab Jeffrey , Anderson Ann , Eggers Scott D. , Lohse Christine , McCaslin Devin L. 
Published: April 2023

Purpose:
This study aimed to describe the relationship between changes in pre and post self-perceived dizziness handicap, scores on the patient health questionnaire, and perceptions of patient's value of being evaluated and managed by a multidisciplinary team.

Method:
Seventy-eight patients completed the Dizziness Handicap Inventory (DHI) and Patient Health Questionnaire–Fourth Edition (PHQ-4) questionnaires post multidisciplinary clinical consultations and testing for the chief complaints of dizziness, unsteadiness, vertigo, or balance problems. The diagnoses of each patient were recorded from the clinical reports of each specialty consultation and were classified as structural, functional, or psychiatric. They were contacted by phone at least 6 months after their visit to obtain feedback regarding their symptoms and overall patient experience.

Results:

The change in DHI total score did not differ significantly by diagnosis (
p
= .56), indicating that patients experienced an improvement in DHI total score regardless of diagnosis. PHQ-4 anxiety scores worsened by a mean of 0.7 points for those with structural diagnoses (
p
= .04), improved by a mean of 0.7 points for psychiatric diagnoses (
p
= .16), and improved by a mean of 0.3 points for functional diagnoses (
p
= .39). Only seven patients would not recommend the team to a family or friend; these patients tended to report worsening DHI total scores (
p
= .27) compared to the significant improvement in DHI total scores for patients who would make such a recommendation (
p
< .001). Similarly, only 13 patients did not feel the information they received had a positive impact; these patients tended to report worsening DHI total scores (
p
= .18) compared to the significant improvement in DHI total scores for patients who did feel the information had a positive impact (
p
< .001).

Discussion:
The assessment and management of patients with chronic dizziness is challenging due to symptoms arising from multiple etiologies. Our finding of a vast difference between high satisfaction and relatively unchanged dizziness handicap suggests that there is value in seeing a multidisciplinary team where consultations are unhurried, care is coordinated, and expectations regarding treatment can be managed.
A Vocal Hygiene Program for Mitigating the Effects of Occupational Vocal Demand in Primary School Teachers
Authors: Lin Kelly Jie Ying , Chan Roger W. , Wu Chia-Hsin , Liu Sally Chien Hsin 
Published: April 2023

Purpose:
Teachers are occupational voice users with significant vocal demand. This study examined if a vocal hygiene program could mitigate the effects of occupational vocal demand in primary school teachers across 1 month.

Method:

Sixty female teachers participated, with 30 in an experimental group receiving vocal hygiene education plus daily home practice for 1 month and 30 in a control group with no intervention. Their vocal changes across the month were quantified with (a) acoustic measures on fundamental frequency (
f
o
), vocal intensity, jitter and shimmer, harmonics-to-noise ratio, and smoothed cepstral peak prominence and (b) Voice Handicap Index (VHI-10) and Vocal Fatigue Index (VFI) scores.

Results:

Analysis of covariance showed significantly larger changes (significant decreases) in conversational
f
o
and in jitter for the experimental group relative to the control group. Post hoc pairwise comparisons following repeated-measures analysis of variance showed significant decreases in conversational
f
o
and in jitter across the month for the experimental group. No significant differences in VHI-10 and VFI scores were found between the groups.

Conclusions:
Vocal demand–related changes in acoustic measures could be partially mitigated with the vocal hygiene program. Future studies with a more refined intervention program and more long-term follow-up are recommended to better understand the long-term benefits of vocal hygiene programs on primary school teachers.
Branding Kristianstad: a case of rebranding and stakeholder engagement
Authors: Källström Lisa , Siljeklint Per 
Published: April 2023

AbstractKristianstad is today in the process of implementing its third place brand in less than 20 years. The purpose of this case study is to describe Kristianstad’s place branding journey with a special focus on the place stakeholders and their involvement and engagement—a case of both rebranding and participatory place branding. The case study describes Kristianstad’s three distinct branding initiatives, with focus on their initiators, engagement and implementation. It is based on a collaboration with Kristianstad municipality and a descriptive approach was employed. Empirical materials were collected through interviews and active participation in workshops and meetings. The case describes Kristianstad’s place branding journey and illustrates how place stakeholders’ previous involvement and experiences influence their behaviours and perceptions of the current place brand as well as the continuing place branding process. The three main takeaways are: past experiences matter; it matters where the place brand initiative comes from; and engagement matters more than profile. Kristianstad municipality’s place branding journey shows the difficulties with rebranding a place, more specifically highlighting place stakeholders’ engagement over time.
Revisiting tropical pasture intake: what has changed in 50 years?
Authors: Charmley E. , Thomas D. , Bishop-Hurley G. J. 
Published: April 2023

The measurement and prediction of pasture intake in extensive grazing systems, typical of northern Australia, remain elusive after 50 years of research. The aim of this paper is to review research conducted over the past 50 years, highlight advances in understanding, discuss remaining challenges and consider future developments with digital technologies. While the fundamental components of voluntary intake are well understood, their measurement is difficult, particularly in extensive grazing systems, which has limited the development of predictive models that adequately address the interplay of factors influencing intake from the bite to the landscape scale. Ongoing research by the authors is used as an example to highlight the potential application of digital technologies to overcome limitations in measurement and prediction. Digital technologies offer the opportunity for monitoring factors that control voluntary pasture intake at scale and under commercial conditions. However, our ability to ground-truth novel indices of intake remains limited without ongoing development of physical methods. This will limit the accuracy and precision of predictive models incorporating digital technologies that can be applied to the extensive grazing conditions of northern Australia. The advent of precision livestock management for extensive cattle production is essential if the industry is to remain viable in the future where production is transparent, ethically sound and environmentally defensible as well as profitable.
A countess as goat and a duke as boar
Authors: Wackers Paul 
Published: April 2023

Abstract
This article studies three medieval texts in which specific historical persons are presented as animals to
comment upon their behaviour and on the situation they were in. The choice of representing animals is studied, as are the literary
techniques and the meaning of the texts. It is argued that this meaning is always general, and older scholarly interpretations,
that are more specific, are rejected. An explanation is suggested for the rarity of this type of ‘animal story as political
commentary’, and it is argued that this type is fundamentally different from the passages in traditional animal stories which have
previously been assumed also to contain veiled political commentary.
Revisiting Andreev processes in superconductor-graphene-superconductor (SGS) Josephson junctions: comparison with experimental results
Authors: Salim Shahrukh , Marathe Rahul , Ghosh Sankalpa 
Published: April 2023

Abstract
In view of the recent progress in experiments on charge transport through various Josephson junctions made out of graphene, we have made a careful comparison between the theory and some of the available experimental results. Within the framework of a transfer matrix approach, we have first analytically derived the spectrum of Andreev bound states (ABS) in a superconductor -graphene-superconductor (SGS) junction for a wide range of experimentally relevant parameters. We have particularly considered the case of monolayer graphene (MLG). The theoretical results can account for both the retro Andreev reflection (RAR) and the specular Andreev reflection (SAR) in the relevant parameter range. Using the ABS spectrum we have evaluated the current through such junctions and the junction conductance from the analytically derived expressions at different bias voltages for a range of other system parameters directly taken from the experimental works. These theoretical results have then been compared with experimental results. Evaluated current and the conductance show scaling behaviour with change in the junction length and agree well with the experimental results. In the relevant parameter regime where the SAR process is dominant, the calculated values of the current and the conductivity have been found much lower than the corresponding values observed when the RAR process is dominant.
Detection of hazardous greenhouse gases and chemicals with topological edge state using periodically arranged cross-sections
Authors: Zaky Zaky A , Mohaseb M A , Aly Arafa H 
Published: April 2023

Abstract
This study investigates a sensitive chemical and hazardous greenhouse gas sensor using ternary phononic crystals composed of periodic tubes. The sensing mechanism depends on the localization of the topological edge state at the interface between phononic crystals. The impact of the structure’s geometry and concentration of a specific gas in air are discussed. Further, the effect of temperature on the position of topological edge state and the sensitivity of the proposed sensor will be studied. This model has shown good sensitivity of 1.58 Hz m−1 s and a figure of merit of 33.7 m−1 s to distinguish different chemical and hazardous greenhouse gas. Furthermore, the proposed detector is low-cost and simple because it does not require a complicated procedure to fabricate multilayers with different mechanical properties.
Deterministic joint remote state preparation via a non-maximally entangled channel
Authors: Xin Xuanxuan , He Shiwen , Li Yongxing , Li Chong 
Published: April 2023

Abstract
Ideal deterministic quantum communication tasks require maximally entangled channels. The reality is that the maximally entangled channel is inevitably degraded to a generally entangled one because of various decoherence mechanisms, seriously deteriorating the performance of quantum communication. In most cases, entanglement purification and distillation are utilized to improve the entanglement and to construct the maximally entangled channel. In this paper, we proposed an alternative scheme to realize deterministic joint remote state preparation using a non-maximally entangled channel. Instead of spending additional entanglement resources in advance for entanglement purification or distillation, only two non-entangled ancillaries are employed in this scheme. Whether the employed quantum channel is a maximally entangled channel or a generally entangled one, remote state preparation would never fail theoretically in this investigation. This protocol provides a feasible way for the construction of practical quantum networks.
Discrimination of geometrically uniform states and the no-signaling principle
Authors: Lü Xin 
Published: April 2023

Abstract
The link between quantum state discrimination and the no-signaling principle is applied to discriminating geometrically uniform states. Specifically, the original discrimination problem is converted to constructing the complementary matrix with predetermined off-diagonal entries. Two such constructions are given explicitly, and therefore three upper bounds on the success probability are derived. Those upper bounds are then employed to estimate the robustness of coherence, where we establish a larger class of states with equal robustness of coherence and l
1-norm of coherence, and provide the exact answer of the robustness of coherence for any states that are diagonalized by Hadamard matrices.

Published: April 2023

Abstract
Due to the hydraulic characteristics of the runner, the hydraulic transition process of the pumped-storage hydroelectricity is complicated, and it has a greater impact on the safe operation of the waterway system. Therefore, simulation and analysis of the hydraulic transition process are essential when designing a pumped-storage hydroelectricity. Based on the four-image characteristic curve of the pump-turbine runner of a pumped-storage hydroelectricity with double surge tanks, guide vane closing laws, and the layout of the water delivery system, this paper conducts computer simulation and analysis of the hydraulic transition process of the power delivery system. This paper also presents how the representative parameters (e.g. unit rotation speed and pressure in the water delivery system) of the water delivery system change in various cases. The results show that the various indexes of the hydraulic process of the pumped-storage hydroelectricity meet the control requirements. This paper also provides the optimization to the design of the water delivery system of the pumped-storage hydroelectricity.

Published: April 2023

Abstract
Energy storage station (ESS) has been allowed to provide ancillary services in power markets in recent years. It is a high-quality resource for regulation services and can promote renewable energy consumption. Existing studies have yet to consider the battery degradation cost when using ESS to provide regulation service. This paper establishes a model to quantify the ESS’s degradation cost and proposes a market-clearing model integrated with such a cost to address this issue. The model is verified by case studies. Key factors affecting the revenue and performance of ESS providing regulation services are also analyzed.

Abstract
The effects of thermal load 1662W and 3740W respectively, the maximum furnace temperature 450°C and 600°C on the starting characteristics of the sulfur heat pipe is studied by using sulfur as a working fluid. The experimental data show that when the maximum furnace temperature is fixed, increasing the heating power can reduce the starting time; if the heating load is constant, the temperature of the pipe wall increases with the rise of the maximum temperature of the furnace; when the sulfur heat pipe is stable, the thermal resistance reduces with the grow of heating power and the heat transfer performance is also greatly improved; the heating power is 3740W and the maximum furnace temperature is 600 °C, which is the best condition for starting the heat pipe.

Published: April 2023

Abstract
The location planning of battery-swapping stations needs to consider many factors. This paper is based on the location planning of battery-swapping stations and considers limits on the number of electric material vehicles and battery packs. Firstly, a rapid vehicle exchange model for battery-swapping stations is established. On this basis, a steady-state model of the vehicle transporting materials is established, which describes the regular and dynamic operation of the whole vehicle dispatching system based on maximizing the number of vehicles always transporting materials on the road. Finally, a material transportation target planning model is established. NSGA-II is used to solve the maximum material transportation target planning function for the best selection of battery-swapping station sites and the best number of vehicles and battery packs for material transportation.

Published: April 2023

Abstract
To investigate the association between the failure pattern and the proportion of external load in the tower segment, the capacity experiment of the scaled segment model is designed in this paper, and the FE model of the experiment of the segment is build and compared with experiment results. The pattern of the tower segment failed is evaluated by the relationship of PH(horizontal load) and MP (bending moment). The critical points of P-MP curve were analyzed by selecting the capacity of diagonal and main elements. And the failure assessment theory for the tower segment was established. The results indicate that the FE model of the experiment segment can reflect the experiment loading process effectively. The capacity of the diagonal element has a significant impact on the tower’s PH, and the main element’s bearing capacity is an important factor affecting the flexural capacity. Using the proposed method, the weak positions and elements of the structure can be judged.
