ABSTRACT
Owing to the intrinsic excellent mechanical, electrical, and thermal properties of carbon nanotubes (CNTs), carbon nanotube fibers (CNTFs) have been expected to become promising candidates for the next-generation of high-performance fibers. They have received considerable interest for cutting-edge applications, such as ultra-light electric wire, aerospace craft, military equipment, and space elevators. Wet-spinning is a broadly utilized commercial technique for high-performance fiber manufacturing. Thus, compared with array spinning from drawable CNTs vertical array and direct dry spinning from floating catalyst chemical vapor deposition (FCCVD), the wet-spinning technique is considered to be a promising strategy to realize the production of CNTFs on a large scale. In this tutorial review, we begin with a summative description of CNTFs wet-spinning process. Then, we discuss the high-concentration CNTs wet-spinning dope preparation strategies and corresponding non-covalent adsorption/charge transfer mechanisms. The filament solidification during the coagulation process is another critical procedure for determining the configurations and properties for derived CNTFs. Next, we discuss post-treatment, including continuous drafting and thermal annealing, to further optimize the CNTs orientation and compact configuration. Finally, we summarize the physical property-structure relationship to give insights for further performance promotion in order to satisfy the prerequisite for detailed application. Insights into propelling high-performance CNTFs production from lab-scale to industry-scale are proposed, in anticipation of this novel fiber having an impact on our lives in the near future.
Dark supernova remnant buried in the Galactic Center “Brick” G0.253+0.016 revealed by an expanding CO-line bubble
Authors: Sofue Yoshiaki 
Published: June 2024

Abstract
We performed a $^{12}$CO- and $^{13}$CO-line study of the “Brick” (G0.253+0.016) in the Galactic Center (GC) by analyzing archival data obtained with the Nobeyama 45 m telescope. We present kinematics and molecular gas distributions in the longitude–velocity diagram, and suggest that the Brick is located along the GC Arm I in the central molecular zone (CMZ), which yields a distance from the Sun of 8 kpc and a Galactocentric distance of 0.2 kpc. The major- and minor-axis diameters of the Brick are $D_x\times D_y=8.4 \times 4.1\, {\rm pc}$ at position angles of 40 and $130^\circ$, respectively, and the scale radius is $r_{\rm Bri}=\sqrt{D_x D_y}=2.96\, {\rm pc}$. The molecular mass inferred from the $^{12}$CO-line integrated intensity is $M_{\mathrm{Bri};X_\mathrm{CO}}\sim 5.1\times 10^4\, M_\odot$ for a conversion factor $X_{\rm CO;GC}=1.0\times 10^{20}$ H$_2$ cm $^{-2}$ [K km s$^{-1}]^{-1}$. On the other hand, the dynamical (virial) mass for the measured velocity dispersion of $\sigma _v=10.0\, {\rm km\ s^{-1}}$ is calculated to be $M_{\rm Bri;vir}\sim 6.8 \times 10^4\,M_\odot$, which yields a new conversion factor of $X_{\rm CO;Bri}=1.3\times 10^{20}$ H$_2$ cm $^{-2}$ [K km s$^{-1}]^{-1}$. The Brick’s center has a cavity surrounded by a spherical molecular bubble of radius $r_{\rm bub}=1.85$ pc and mass $\sim 1.7\times 10^4\,M_\odot$ expanding at $v_{\rm exp}\simeq 10 \ {\rm km\ s^{-1}}$ with a kinetic energy of $E_0\sim 1.7\times 10^{49}$ erg. If the bubble is approximated by an adiabatic spherical shock wave, the age is estimated to be $t\sim 2/5 r_{\rm bub}/v_{\rm exp}\sim 7.2\times 10^4$ yr. Neither non-thermal radio structures nor thermal radio emission indicative of the H ii region are found in the archival data from MeerKAT. We suggest that the molecular bubble is a dark supernova remnant buried in the Brick, which has therefore experienced past (${\sim}0.1$ Myr ago) massive star formation with a supernova explosion.
Higgs Inflation in Unimodular Gravity
Authors: Nozari Kourosh , Malekpour Manda 
Published: June 2024

Abstract
The discovery of the Higgs mechanism within the context of spontaneous symmetry breaking has offered a new perspective on early-time cosmic inflation and also on the relationship between elementary particles and dark energy, believed to drive the universe’s accelerating expansion. We suggest an inflation scenario driven by the Higgs boson within the framework of unimodular gravity, where the Higgs field acts as the inflaton and has a significant non-minimal coupling to the gravity. We present a detailed analysis of the problem in the Jordan and then Einstein frame for a unimodular Higgs inflation, followed by a comparison of our findings with the cosmic microwave background observations made by the Planck Collaboration and other joint data sets. Therefore, new constraints are imposed on the non-minimal coupling parameter, $\xi$, by determining the magnitudes required for effective cosmic inflation. We demonstrate that a substantial non-minimal coupling of order $\xi \sim 10^{2}\!-\!10^{4}$ is required for this model to match with the observed primordial spectrum.
Gravitational Waves from First-Order Phase Transition in an Electroweakly Interacting Vector Dark Matter Model
Authors: Abe Tomohiro , Hashino Katsuya 
Published: June 2024

Abstract
We discuss gravitational waves (GWs) in an electroweakly interacting vector dark matter (DM) model. In the model, the electroweak gauge symmetry is extended to SU(2)$_0 \times$SU(2)$_1 \times$SU(2)$_2 \times$U(1)$_Y$ and spontaneously broken into SU(2)$_L \times$U(1)$_Y$ at TeV scale. The model has an exchange symmetry between SU(2)$_0$ and SU(2)$_2$. This symmetry stabilizes some massive vector bosons associated with the spontaneous symmetry breaking described above, and an electrically neutral one is a DM candidate. In a previous study, it was found that the gauge couplings of SU(2)$_0$ and SU(2)$_1$ are relatively large to explain the measured value of the DM energy density via the freeze-out mechanism. With the large gauge couplings, the gauge bosons potentially have a sizable effect on the scalar potential. In this paper, we focus on the phase transition of SU(2)$_0 \times$SU(2)$_1 \times$SU(2)$_2 \rightarrow$ SU(2)$_L$. We calculate the effective potential at finite temperature and find that the phase transition is first-order and strong in a wide range of the parameter space. The strong first-order phase transition generates GWs. We calculate the GW spectrum and find that it will be possible to detect the GWs predicted in the model by future space-based GW interferometers. We explore the regions of the parameter space probed by the GW detection. We find that the GW detection can probe the region where the mass of $h^{\prime }$, a CP-even scalar in the model, is a few TeV.

Published: June 2024

AbstractAtherosclerosis, a chronic and progressive condition characterized by the accumulation of inflammatory cells and lipids within artery walls, remains a leading cause of cardiovascular diseases globally. Despite considerable advancements in drug therapeutic strategies aimed at managing atherosclerosis, more effective treatment options for atherosclerosis are still warranted. In this pursuit, the emergence of β-cyclodextrin (β-CD) as a promising therapeutic agent offers a novel therapeutic approach to drug delivery targeting atherosclerosis. The hydrophobic cavity of β-CD facilitates its role as a carrier, enabling the encapsulation and delivery of various therapeutic compounds to affected sites within the vasculature. Notably, β-CD-based nanoassemblies possess the ability to reduce cholesterol levels, mitigate inflammation, solubilize hydrophobic drugs and deliver drugs to affected tissues, making these nanocomponents promising candidates for atherosclerosis management. This review focuses on three major classes of β-CD-based nanoassemblies, including β-CD derivatives-based, β-CD/polymer conjugates-based and polymer β-CD-based nanoassemblies, highlighting a variety of formulations and assembly methods to improve drug delivery and therapeutic efficacy. These β-CD-based nanoassemblies exhibit a variety of therapeutic mechanisms for atherosclerosis and offer systematic strategies for overcoming barriers to drug delivery. Finally, we discuss the present obstacles and potential opportunities in the development and application of β-CD-based nanoassemblies as novel therapeutics for managing atherosclerosis and addressing cardiovascular diseases.

Published: June 2024

Abstract

Introduction
Aluminum phosphide (ALP) is a highly toxic rodenticide and the mortality rates caused by it have been demonstrated up to 70–100% in various studies. Unfortunately, there is no specific antidote to manage its toxic effects. This study aimed to assess the biochemical and clinical efficacy and safety of intravenous lipid emulsion as an adjuvant therapy in acute aluminum phosphide poisoning.

Patients and methods
Sixty-four cases with acute ALP poisoning were stratified according to severity by the Poison Severity Score into severe and moderate groups (32 patients each). Patients were then randomly allocated into either receiving intravenous lipid emulsion in addition to the conventional treatment or receiving the conventional treatment only by using block randomization.

Results
Treatment by ILE resulted in a significant improvement in the survival time, the mean arterial blood pressure, arterial blood gases, and a significant reduction in serum lactate levels. The need for intubation and mechanical ventilation was insignificantly lower in the intervention groups compared to control groups. However, the reduction in mortality rate in the patients of intervention groups compared with control groups was found to be non-significant. Intravenous lipid emulsion use in acute ALP poisoning significantly prolonged the survival time, improved the metabolic acidosis, decreased the serum lactate levels and increased the mean arterial blood pressure and hospital stay in the intervention groups. And insignificantly decreased the mortality rate, need of intubation and mechanical ventilation, and the total dose of vasopressors.

Authors: Taylor Carly , Loukas Vanessa , Muwonge Jasmine , Taylor Jessica L. , Boyle Joseph 
Published: June 2024

Introduction
Extended-release subcutaneous buprenorphine is an increasingly common treatment for opioid use disorder. Serious adverse events are rare and may be poorly understood. This report describes an early surgical intervention to address tissue necrosis resulting from misplaced subcutaneous buprenorphine injection. We review identifying characteristics that distinguish the necrotic reaction from other adverse effects of subcutaneous buprenorphine and offer guidance to continue treatment with subcutaneous buprenorphine.

Case Report
A 33-year-old patient returned to clinic within an hour of his buprenorphine injection, reporting pain and skin changes unlike his previous injections. Non blanching erythema consistent with early necrosis was evident, and the patient was referred for surgical removal of his buprenorphine depot. The patient had uncomplicated healing of the surgical site and was provided sublingual buprenorphine before returning to continue treatment with subcutaneous buprenorphine.

Discussion
Although skin necrosis is known to be a rare complication of subcutaneous buprenorphine injection, early surgical excision to limit injury has not been described. Signs and symptoms of skin necrosis must be better understood to facilitate early intervention and continued treatment.

Conclusions
This case affirms that a patient may continue treatment with subcutaneous buprenorphine despite suffering skin necrosis and demonstrates the value of early surgical intervention after superficial placement of extended-release buprenorphine.

Modified stapes surgery for otosclerosis: An evaluation of auditory results and postoperative complications
Authors: Chang Chih-En , Chau Ivy Yenwen , Liu Yu-Hsien , Shiao An-Suey 
Published: June 2024

Background:
The senior author Shiao, had introduced a modified version of the traditional stapes surgery, called minimally traumatic stapes surgery (MTSS), and explored its effectiveness in reducing postoperative vertigo. However, MTSS exhibited no significant breakthrough in terms of audiometric results. Building upon the original MTSS through slight modifications and the use of the Medtronic Big Easy® Piston as the prosthesis, this study evaluates a refined version of the original MTSS technique. In particular, this research sought to investigate the impact of this refined approach on hearing outcomes and postoperative complications among patients diagnosed with otosclerosis.

Methods:
This research comprehensively examined the medical records of individuals diagnosed with otosclerosis who underwent MTSS. The postoperative outcomes assessed encompassed hearing outcomes and the occurrence of any new complications.

Results:
Overall, 95 patients diagnosed with otosclerosis (comprising 106 affected ears) underwent MTSS. Significant improvements in both the average air conduction threshold (40 ± 16.82 dB after vs 60 ± 14.56 dB before surgery; p < 0.0001) and average air–bone gap (11.99 ± 7.24 dB after vs 29.65 ± 9.47 dB before surgery; p = 0.003) were observed after the surgery. Conversely, no significant change in the average bone conduction threshold was observed after the procedure (28 ± 13.81 dB after vs 29 ± 12.31 dB before surgery; p = 0.149). Among the 106 affected ears, 102 showed postoperative air–bone gap measurements <20 dB, indicating an impressive 96.2% overall hearing improvement. Notably, only a few postoperative complications were observed, including vertigo, chorda tympani injury, facial weakness, and a slight hearing deterioration.

Conclusion:
The refined MTSS technique promoted significant postoperative hearing improvements with minimal complications. This approach showed potential for addressing the surgical challenges in Asian patients with otosclerosis, emphasizing the importance of further research on this advanced procedural method.
Using Serious Games to Measure Upper-Limb Myoelectric Pattern Recognition Prosthesis Control Performance in an At-Home Environment
Authors: Maas Bart , Wright Zack A. , Lock Blair A. , van der Sluis Corry K. , Bongers Raoul M. 
Published: June 2024

Abstract

Introduction
Upper-limb prostheses have undergone substantial technological improvements in the last two decades, but user complaints and abandonment rates have hardly changed. This may follow from the use of laboratory-based tests when assessing new technology instead of measuring prosthesis use in at-home situations. Serious games might be used to assess prosthesis use at home.

Objectives
The aim of this study was to assess the feasibility, validity, and reliability of using serious games to measure myocontrol in at-home situations.

Study Design
The design of this study is a cohort study with repeated measurements.

Methods
All 10 participants (five males; seven transradial and three transhumeral defects) used pattern recognition (PR) to control their prosthesis. Two serious games were included in the PR software: Simon Says and In-The-Zone. Participants were instructed to use their prosthesis as they normally would for 2 weeks with the additional instruction to play at least 18 serious games (±90 minutes in total). Outcome measures for aspects of prosthesis use were wear time, months of prosthesis use, and user experiences, and serious games outcomes were success rate and completion time.

Results
For feasibility, all but one participant completed the minimum of 18 games, and user experiences were mostly positive. For validity, no relationships were found between the aspects of prosthesis use and performance in the serious games. For reliability, test-retest reliability for success rate was high (intraclass correlation [ICC], 0.79), but low for completion time (ICC, 0.18) in both games.

Conclusions
Feasibility and reliability of using serious games as an assessment instrument for prosthesis control in at-home situations appeared to be good; however, validity could not be established. The serious games should be improved to increase validity. Furthermore, more outcome measures that reveal aspects of prosthesis use should be considered.

Clinical Relevance Statement
Assessing myocontrol in at-home situations by using serious games is feasible and reliable, but validity needs further attention.
Associations of cholecystectomy with the risk of gastroesophageal reflux disease: a Mendelian randomization study
Authors: Qian Jin , Xu Huawei , Liu Jun , Zheng Yihu 
Published: June 2024

Background:
Cholecystectomy is the standard surgery for patients with gallbladder disease, but the impact of cholecystectomy on gastroesophageal reflux disease (GERD) is not clear.

Methods:
The authors obtained genetic variants associated with cholecystectomy at a genome-wide significant level (P-value <5×10-8) as instrumental variables (IVs) and performed Mendelian randomization to explore the relationship with GERD.

Results:
The Inverse Variance Weighted analysis (IVW) showed that the risk of GERD in patients after cholecystectomy increased (OR=2.19; 95% CI: 1.18–4.09). At the same time, the analysis results of weighted median (OR=2.30; 95% CI: 1.51–3.48) and weighted mode (OR=2.21; 95% CI: 1.42–3.45) were also consistent with the direction of the IVW analysis and were statistically significant (P<0.05).

Conclusions:
This study shows that patients who have undergone cholecystectomy are a susceptible population of GERD.

Published: June 2024

Purpose:
To investigate the influence of powered wheelchair standing device (PWSD) use on changes in activity/participation in children with neurodevelopmental conditions.

Methods:
A mixed methods A-B-A single-subject research design was replicated with participants. The target behavior was parental perceptions of changes in children’s performance of activity/participation goals measured via the Canadian Occupational Performance Measure (COPM). Secondary outcome measures included the COPM with children, an interview, and a 3-measure implementation survey. COPM data related to the target behavior were analyzed using the split-middle celeration line method.

Results:
Four child-parent dyads participated in the study. All participants achieved statistically and clinically significant increases in COPM performance ratings for the 5 parent-identified activity/participation goals.

Conclusions:
For the participant dyads in this study, use of the PWSD appeared to positively influence parental perceptions of improvements in their child’s performance of activity/participation goals.

Employees’ unethical pro-organizational behavior and subsequent internal whistle-blowing
Authors: Chen Lixin , Zhang Suchuan 
Published: June 2024

Purpose
This paper aims to investigate how perpetrators who engage in unethical pro-organizational behavior (UPB) feel and respond in the aftermath of such behavior.

Design/methodology/approach
This paper used a two-wave time-lagged design and collected data from 260 full-time employees working in different industries in China.

Findings
The results indicated that UPB was negatively and indirectly associated with internal whistle-blowing through shame. Perceived moral leadership weakened the effect of shame on internal whistle-blowing.

Originality/value
Based on affective events theory, this paper explored an integrated behavior-emotion-behavior sequence. This paper proposed that the negative emotion, shame, evoked by UPB subsequently influences the extent to which UPB perpetrators engage in internal whistle-blowing.
