Abstract
Zinc oxide (ZnO) has the advantages of wide bandgap, rich resources, simple preparation, and environmental friendliness, which is a type of ultraviolet (UV) detector material with great potential for development. However, the complicated preparation processes and complex device structures limit the application of ZnO UV detectors. Therefore, in this study, a high-performance UV detector was successfully fabricated based on graphene quantum dot-sensitized GaP@ZnO nanocomposite (GQDs/GaP@ZnO) thin films deposited using a simple spin-coating method. The GQDs/GaP@ZnO device exhibits higher responsivity of 142.2 A W−1, excellent detectivity of 1.1 × 1012 Jones, and a higher external quantum efficiency of 4.85 × 104% under the conditions of 365 nm UV light (0.078 mW cm−2) and external voltage of 6 V. In addition, this study provides a new research method for the preparation of high-performance optoelectronic devices using the cumulative synergistic effect of material composites and surface modification.
Direct transformation of equilateral hexagonal Frank vacancy loops to stacking fault tetrahedra under thermal fluctuation

Published: July 2022

Abstract
Stacking fault tetrahedra (SFTs) are highly interesting three-dimensional vacancy defects in quenched, plastically deformed or irradiated face-centered-cubic metals and have a significant impact on the properties and subsequent microstructural evolution of the materials. Their formation mechanism and stability relative to two-dimensional vacancy loops are still debated. Equilateral hexagonal Frank vacancy loops (faulted, sessile) observed in microscopy have been considered unable to directly transform to SFTs due to separation of Shockley partial dislocations as well as embryonic stacking faults. Here using sufficiently long (up to tens of nanoseconds) molecular dynamic simulations, we demonstrate that such a transformation can in fact take place spontaneously at elevated temperatures under thermal fluctuation, reducing potential energy of defected atoms by <0.05 eV/atom. The transformation becomes easier with increasing temperature or decreasing loop size.

Published: July 2022

Abstract
The geometry and calibration of three-dimensional multi-beam laser scanning (MBLS) is more difficult than single-beam laser scanning, especially for a one laser emitter and multiple laser-echo detection within the same optical path and scanning with a two-axis-mirror. This paper focuses on the influence of the main systematic errors upon the geometric imagery of the MBLS, and presents a plane-based self-calibration method to improve the geometric positioning. First, the model for geometric imaging and systematic errors for the MBLS is presented, and the adjustment of the plane-based self-calibration is developed. Second, the influence of systematic errors upon geometric imagery of the MBLS is simulated and conducted to find the main errors. Third, a strong network configuration based on planar calibration is addressed and implemented, and the improvement of accuracy is examined via qualitative and quantitative analysis. The results show that the rangefinder offset, horizontal direction circle index and vertical circle index are the main systematic errors. The accuracy of distance is corrected from 29.94 cm to 2.86 cm with an improvement of 86.89% for the plane-based calibration, and validation indicates that this is corrected from 25.47 cm to 5.60 cm with an improvement of 88.25%.

Published: July 2022

Abstract
Well-defined polyhedral ZIF-67 metal-organic frameworks (MOFs) are usually synthesized using methanol as solvent. In this work, methanol is replaced with deionized water as a solvent to synthesize ZIF-67 MOFs with unique nanoflake morphology. The ZIF-67 nanoflakes are synthesized directly by in situ method on reduced graphene oxide (rGO) to obtain ZIF-67/rGO-x precursors which are further transformed into NiCo-layered double hydroxide nanocomposites (NiCo-LDH/rGO-x, x = 10, 30, 50 and 90 mg of rGO). The NiCo-LDH/rGO-x nanostructured composites are found to be excellent materials for battery type supercapacitor (supercapattery) applications. Among these samples, the NiCo-LDH/rGO-30 composite gives maximum specific capacity of 829 C g−1 (1658 F g−1) at a current density of 1 A g−1 and high rate capability.

The device can show good capacity retention even after 3000 continuous charge–discharge cycles. The NiCo-LDH/rGO-30 composite, in situ derived from ZIF-67 MOF in combination with optimal amount of rGO, is an excellent material to deliver both high energy density and high power density in supercapattery devices.
Fine modulation of the energy band strategy to control the carrier confinement capability of digital alloys

Published: July 2022

Abstract
In this paper, a strategy to finely modulate the energy band structure to control the carrier confinement capability of digital alloys (DA) is proposed. Strain analysis shows that As and Sb atoms are exchanged within the AlAsSb DA. The bottom of the corrected potential well is low on the left and high on the right in the growth direction, resulting in a higher band offset of the AlSb potential barrier layer on the left side of the potential well than on the right side. The modulation of the band leads to a higher probability of electron tunneling in DA under the action of an electric field opposite to the growth direction. Conversely, it is difficult for the electrons to tunnel into the lower energy level potential wells. The I–V curve of DA shows that the current value under positive bias is significantly smaller than the value under negative bias when the voltage is higher. The measured results correspond perfectly with the modified energy band model, which verifies the feasibility of energy band modulation. This is important for the structural design of DA and the reduction of dark current in optoelectronic devices.
Impact of image quality on radiomics applications
Authors: Cui Yunfeng , Yin Fang-Fang 
Published: July 2022

Abstract
Radiomics features extracted from medical images have been widely reported to be useful in the patient specific outcome modeling for variety of assessment and prediction purposes. Successful application of radiomics features as imaging biomarkers, however, is dependent on the robustness of the approach to the variation in each step of the modeling workflow. Variation in the input image quality is one of the main sources that impacts the reproducibility of radiomics analysis when a model is applied to broader range of medical imaging data. The quality of medical image is generally affected by both the scanner related factors such as image acquisition/reconstruction settings and the patient related factors such as patient motion. This article aimed to review the published literatures in this field that reported the impact of various imaging factors on the radiomics features through the change in image quality. The literatures were categorized by different imaging modalities and also tabulated based on the imaging parameters and the class of radiomics features included in the study. Strategies for image quality standardization were discussed based on the relevant literatures and recommendations for reducing the impact of image quality variation on the radiomics in multi-institutional clinical trial were summarized at the end of this article.

Abstract
III–V semiconductor nanostructures with subwavelength scale dimensions have demonstrated outstanding photon trapping and carrier transport characteristics, and may be coupled readily with organic polymers and cheap substrates to create hybrid solar cells (HSCs). In this work, we have presented a comprehensive optoelectronic study of Poly(3-hexylthiophene): [6,6]-phenyl C61-butyric acid methylester (P3HT:PCBM)/Gallium arsenide (GaAs) nanocone (NC) array based HSC and compared its overall performance with its organic counterpart and other nanostructure arrays. The proposed P3HT:PCBM/GaAs NC HSC has exhibited an average absorptance of 71.63% with a remarkable optical J
sc and generation rate of 24.21 mA cm−2 and 5.26 × 1028 cm−3s−1, respectively, which are highest among all the other structures. Additionally, we have presented the optical performance of the HSC for oblique incident conditions and reported that the proposed HSC can exhibit an average optical J
sc of 21.04 mA cm−2 when averaged over all angles of incidence. The electrical simulations reveal that, the proposed device can exhibit a power conversion efficiency of 17%, even at low carrier mobility (µ), lifetimes (τ), and high surface recombination velocity at contacts.
Free-standing single-helical woolen yarn artificial muscles with robust and trainable humidity-sensing actuation by eco-friendly treatment strategies
Authors: Peng Yangyang , Zhou Xingxing , Wu Jing , Sheng Nan , Yang Mengxin , Sun Fengxin 
Published: July 2022

Abstract
Twisted yarn artificial muscles have attracted great interests for diverse applications, such as soft robotics, miniaturization controllers and smart textiles. A challenging issue in fabricating the twisted yarn artificial muscles is to retain the inserted twist. Different from the exiting strategies of forming double-helical structures or harnessing complex chemical technologies, we herein propose a simple combination of plasma and UV-light treatments to train natural wools into twist-stable single-helical yarn artificial muscles without external torsional tethering, which realizes easy fabrication of twisted actuators, and achieves better moisture-actuating performance (nearly five times higher in maximum rotation) compared to equivalent double-helical actuators. The stable morphology of woolen yarn muscles affected by the opening and closing of disulfide bonds is explained from microstructure characterization and theoretical analysis. The charming properties of single-helical yarn muscles will provide new inspiration for the development of fiber-based actuators in industrial routines, which is expected to promote the practical application of yarn muscles in smart textiles and wider fields.

Published: July 2022

Abstract
2D shape memory composite tubes, which has excellent flexibility and high durability, have been widely used in intelligent material design. Here we report fabrication of an over-braiding pure shape memory polyurethane (SMPU) and continuous carbon fiber reinforced SMPU (CCF/SMPU) braided tubes with different braided layers (L1, L2, L3). The dynamic thermomechanical behaviors, tensile properties, shape memory behaviors and tensile recovery forces had been investigated. Tensile shape recovery force was recorded to find effects of recovery temperature, applied voltage on the shape memory behaviors. We found that the tensile load, shape recovery ratio and recovery force increase with the braided layers increased. The maximum shape recovery ratio could be reached to 98.8% and shape recovery force of over-braiding CCF/SMPU composite tube was up to 14.825 N. The infilling of carbon fibers could improve the tensile strength and shape memory behaviors simultaneously. Such an effect could be benefit to explore applications of braided composite structures both with high strength and deformation recovery capacity.
Elementary excitations in a spin–orbit-coupled spin-1 Bose–Einstein condensate
Authors: Chen Yuanyuan , Lyu Hao , Xu Yong , Zhang Yongping 
Published: July 2022

Abstract
While a spin–orbit-coupled spin-1 Bose–Einstein condensate (BEC) has been experimentally observed, its elementary excitations remain unclear in the stripe phase. Here, we systematically study the elementary excitations in three distinct phases of a spin–orbit-coupled spin-1 BEC. We find that the excitation spectrum as well as the corresponding static response function and structure factor depend strongly on spin–orbit coupling parameters such as the quadratic Zeeman field and the Rabi frequency. In the stripe phase, besides two gapless Goldstone modes, we show the existence of roton excitations. Finally, we demonstrate that quantum phase transitions between these different phases including the zero-momentum, plane wave and stripe phases are characterized by the sound velocities and the quantum depletion.

Published: July 2022

Abstract
The present work is intended to fabricate titanium diboride (TiB2) and yttrium oxide (Y2O3) fused bronze metal matrix composite by stir casting technique to achieve effective mechanical and corrosion properties. TiB2-Y2O3 nanocomposite powders were synthesized using the mechanical milling synthesis technique. Spectroscopic analyses like Powder x-ray Diffraction (PXRD), Fourier Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscope (SEM) were used to characterize the synthesizednanopowders. The XRD data revealed the average crystalline size of 110 ± 5nanometres with a hexagonal and cubic phase structure of TiB2 and Y2O3. The fundamental modes and other functional groups of the nanocomposite were analyzed using the FTIR analysis. The SEM images revealed the irregular morphological structures of the composite powders. The bronze metal matrix composite is fabricated by varying the weight percentage of TiB2-Y2O3 nanocomposite as 2%, 4%, and 6 wt% with bronze alloy via stir casting technique.XRD graphs revealed the formation of metal matrix composite and the FESEM graphs revealed the porous morphology of the composite. The mechanical performance of the composite was analyzed by using the tensile, compression, and hardness tests. Specimen with 4 wt% reinforcement material offered higher mechanical properties with 303 MPa tensile, 810 MPa compression,141 HRB hardness, and good corrosion resistance. Hence the fabricated TiB2-Y2O3 fused bronze metal matrix composite with good mechanical and corrosion properties can be used for various sea environment applications.
A new preparation scheme for the wettability-patterned copper surfaces and its applicability
Authors: Luo Yuanqiang , Huang Guangwen , Peng Yi , Liang Zhen , He Yugang 
Published: July 2022

Abstract
Droplet control technology has broad application prospects and the wettability-patterned surface is a popular way to realize it. However, the existing preparation methods are either not suitable for copper or not suitable for its batch fabrication. In this paper, three specific preparation schemes with different effects are proposed for the wettability-patterned copper surfaces. Then the influences of preparation conditions on the contact angle are investigated. Using the selected preparation conditions, the effects among different preparation schemes are compared and the wettability-patterned copper surface prepared following preparation scheme 3 shows the best effect. Subsequently, according to different design purposes, the motions and spreading of water droplets on wettability-patterned copper surfaces with four new patterns are observed. It indicates that the hydrophilicity/hydrophobicity and directional liquid transport functions basically reach the pre-designed effects, which verifies the applicability of preparation scheme 3 on the wettability-patterned copper surfaces with different patterns for droplet control. Finally, compared with the existing preparation schemes, only the new preparation scheme proposed in this paper is conducted under room temperature and it does not require any special equipment. What’s more, its preparation time is the shortest (18 min). Hence, it is suitable for batch fabrication, which can extend the applications of wettability-patterned copper surfaces.
Pkgndep: a tool for analyzing dependency heaviness of R packages
Authors: Gu Zuguang , Hübschmann Daniel 
Published: July 2022

Abstract

Summary
Numerous R packages have been developed for bioinformatics analysis in the last decade and dependencies among packages have become critical issues to consider. In this work, we proposed a new metric named dependency heaviness that measures the number of dependencies that a parent uniquely brings to a package and we proposed possible solutions for reducing the complexity of dependencies by optimizing the use of heavy parents. We implemented the metric in a new R package pkgndep which provides an intuitive way for dependency heaviness analysis. Based on pkgndep, we additionally performed a global analysis of dependency heaviness on CRAN and Bioconductor ecosystems and we revealed top packages that have significant contributions of high dependency heaviness to their child packages.

Availability and implementation
The package pkgndep and documentations are freely available from the Comprehensive R Archive Network https://cran.r-project.org/package=pkgndep. The dependency heaviness analysis for all 22 076 CRAN and Bioconductor packages retrieved on June 8, 2022 are available at https://pkgndep.github.io/.

Published: July 2022

Abstract

Background
Extracervical approaches for thyroidectomy are seldom explored in the western population. The objective of this study was to evaluate the outcomes of hemithyroidectomy via endoscopic unilateral axillo-breast approach (UABA) with gas insufflation.

Method
Consecutive patients undergoing UABA hemithyroidectomy for symptomatic benign or cytologically indeterminate nodules (Bethesda III lesions) of less than 5 cm from July 2015 to December 2020 at three European institutions were included. Patients were excluded if presenting with a BMI more than 25 kg/m2, had previous neck surgery and/or radiation, had bilateral thyroid lesions, retrosternal goitre, Hashimoto thyroiditis or Graves’ disease. Follow-up was carried out at 2 weeks, 3 months and 1 year. Outcomes of interest were surgical (including operating time, mean duration of hospital stay and complications) and self-assessed cosmetic outcomes.

Results
Out of 984 patients treated with hemithyroidectomy during the study interval, 253 were selected, including 214 women and 39 men. Patients’ mean age was of 46.6 years with a mean BMI of 22.57. Mean operating time was 72.9 minutes. A transient recurrent laryngeal nerve injury was reported in 3.6 per cent of the patients, but none was persistent. Transient pectoral/cervical hypoesthesia was noted in 24.1 per cent of patients, with no permanent hypoesthesia. Skin burns and subcutaneous hematoma developed in 2.4 per cent and 2 per cent of patients but resolved within the third month after surgery. There was no tracheal/oesophageal perforation, conversion to open surgery or reoperation. The final pathology revealed 241 benign nodules, nine underlying papillary thyroid carcinomas, and three cases of follicular carcinoma. Hospital discharge was achieved on the first in 68.8 per cent of the patients and on the second postoperative day in 31.2 per cent of the cases. All patients were satisfied with the cosmetic aspect.

Conclusion
In selected patients, UABA with gas insufflation for hemithyroidectomy could be performed for the treatment of unilateral thyroid pathologies.
bell hooks’s Legacy and Social Work: A Distillation of Her Key Ideas about Love and Some Implications for Social Work Practice
Authors: Ross Dyann 
Published: July 2022

Abstract
bell hooks is regarded as one of the most influential cultural critics, writers and speakers of the last fifty years. She has published more than forty books which collectively articulate a feminist critique of white supremacy, capitalism and patriarchy. At the same time, she offers a loving, non-violent and just vision for attaining collective and personal well-being. Hooks makes feminist theory meaningful as a guide not only for Black American women but also for anyone seeking to resist inequality and discrimination due to race, class and gender. Her main thesis is that where there is love there can be no oppression. hooks’s contribution is traced through some of the key themes of her books which explicitly refer to love to develop a rich understanding of love and its transformative power. These contributions are then considered for the relevance they have for social work. Social workers can practice love by fostering their own and others’: self-love; willingness to learn; and cultural responsiveness. Two loving practices with other people are dadirri (deep listening) and narrative resistance. Love provides the power to do the justice and healing work.
