AbstractPolycaprolactone (PCL) matrix scaffolds have been extensively studied for tissue engineering applications, which were limited by poor cell adhesion and mechanical strength. Fiber reinforcement modification could be used to improve material properties and optimize material structure. In this study, polylactic acid (PLA) electrospun nanofibers were dispersed in PCL powder, and then the composites were extruded and blended at different traction speed. During the blending and extrusion process, the nanofibrous phase was uniformly dispersed in the matrix, and a kind of tissue engineering scaffold with high connectivity and network structure was prepared using supercritical carbon dioxide foaming. The effect of nanofibers on the foaming behavior of PCL matrix composites prepared at different traction rates was investigated, and the addition of nanofibers promoted the connectivity of the scaffold. Human umbilical vein endothelial cells (HUVECs) culture results showed that the high‐connectivity scaffold was biocompatible and could significantly promote the adhesion and growth of HUVECs. Therefore, fiber‐reinforced porous scaffolds have great application potential in the field of tissue engineering scaffolds.
Parent–teacher communication for children on the autism spectrum: An examination of communication skill use and problematic communication
Authors: Azad Gazi , Sridhar Aksheya , Taormina Isabella , Roter Debra L. 
Published: September 2022

AbstractThe purpose of this investigation was to examine communication skill use and related characteristics, as well as factors associated with problematic communication during conferences, in parents and teachers of children on the autism spectrum (AS). Participants were 36 parent–teacher dyads who completed questionnaires on communication, defined within the Listen, Educate, Assess, Partners, Support (LEAPS) Model, as well as measures on problem‐solving and relationship quality. Parents reported more frequent use of LEAPS‐defined skills than teachers, as well as a more positive view of problem‐solving and relationship quality. Both parents and teachers reported similar levels of problematic communication. Problematic communication was inversely associated with problem‐solving and relationship quality for parents. For teachers, problematic communication was inversely related to skill use and relationship quality. Communication during parent–teacher conferences may be improved through LEAPS‐based communication training for both teachers and parents. This training may diminish problematic communication and align cross‐setting intervention practices, and subsequently optimize outcomes for children on the AS.
Concurrent design error, poor welding, and code inadequacy cause jet‐FIRE on a topping column
Authors: Doglione Roberto , Piccinini Norberto 
Published: September 2022

AbstractThe paper reports the analysis of an accident that occurred in a petroleum refinery. During the start‐up maneuver of the topping column, the anchoring of the riser pipe to metal guide support on the topping column suddenly failed. This caused a rip in the riser pipe, and gasoline squirted out, followed by the ignition of a jet fire. The investigations showed an unusual differential thermal expansion between the topping column and riser. The riser guide to the column was wrongly installed, preventing adequate relative displacements when thermal expansion occurred. Metallographic and fractographic analyses did not discover any inadequacy in the steel of the failed parts. But the lack of penetration of the welding seam resulted in a weak bond between the support and the riser. The high stress induced by the badly installed guide and the weakness of the welding was the cause of the failure and the jet fire. The paper also analyses the application of existing codes to the riser support installation and shows that the code recommendations do not satisfactorily cover the case of topping column risers. The issue is raised to alert operators in the plant, stimulate the improvement of the codes and standards, and avoid future accidents.
Family values, parent roles, and life challenges: Parent reflections on the factors shaping long‐term interest development for young children and their families participating in an early childhood engineering program

Published: September 2022

AbstractInterest is a critical motivating factor shaping how children and youth engage with science, technology, engineering, and mathematics (STEM) inside and outside of school and to what extent they continue to be STEM learners throughout their lives. Emerging evidence over the last several decades indicates that the foundation of STEM‐related interests develops in early childhood, even before children enter the formal education system. Although researchers have documented the emergence of these early interests and their implications for long‐term learning outcomes, there is still much that is not understood about how and why these interests develop, including the role of parents and caregivers in supporting interest development at this age. To explore the processes of early STEM‐related interest development, we recruited 18 low‐income Spanish‐ and English‐speaking parents who had completed an informal engineering education program for preschool‐age children and their families 1–2 years previously. Participants engaged in an in‐depth home‐based interview about their program experience and the subsequent impacts on their children's and families' interests. Using a family systems perspective, we analyzed the ways these families described how their interests related to the program had evolved over the years and the factors that had shaped that process. Findings highlight the diversity of interests that emerge from this type of experience and the ways that family values, parent roles, and life challenges shape the unique interest development patterns of each family.
Synthesis of Axial Bis(benzo[d][1,3]dioxol‐5‐ylmethoxy)phthalocyaninato Silicon (IV): Photophysical and Photochemical Properties and Docking Studies on DNA‐SiPc Interactions

Published: September 2022

AbstractThe synthesis of an axial phthalocyanine compound by the reaction of piperonyl alcohol and SiPcCl2 has been reported. Its structure was characterized by compound 1HNMR,13CNMR, Mass, FTIR and UV visible spectroscopy. Photophysical and photochemical properties of the compound were investigated by fluorescence spectroscopy. The photosensitizer performance of the compound was determined. In addition, with the quantum chemical study, the HOMO ‐ LUMO band gap and the optimized structure of the compound were investigated with two basic sets of the TD‐DFT B3LYP method. The band gap (ΔE) was found to be in the range of 0.6–0.7 eV, and it was determined that the compound would require low energy in the chemotherapeutic interaction with light and in its stimulation. As a chemotherapy drug candidate, its adhesion to protein and DNA structure has been evaluated as in‐silico. In this context, the potential binding and interaction aspects of the new chemotherapeutically effective phthalocyanine compound with two kinds of homo sapiens protein‐DNA complexes were investigated by molecular docking approach. It bonded with the phthalocyanine compound in both crystal structures. A docking score of 6.315 kcal/mol was obtained in the 6DIA encoded DNA polymerase beta substrate complex.

Published: September 2022

AbstractMetabolites are the set of substances produced or utilized in the biochemical process of metabolism known to perform diverse physiological functions in every living organism. As very simple molecules, metabolites can self‐assemble into functional materials for biomedical and nanotechnology applications. Simple amino acid‐based crystals exhibit interesting physicochemical properties of piezoelectricity, fluorescence and optical waveguiding. Combinations of metal‐coordinated metabolites display catalytic properties mimicking natural enzymes for chemical reactions and environmental remediation. Furthermore, excessive accumulation of metabolites spontaneously forms toxic assemblies implicated in the pathogenesis of metabolic and neurodegenerative diseases. Herein, we mainly review the progress of recent three years on the assembly of minimalistic metabolite‐based building blocks into bionanomaterials and their potential applications in energy harvesting, optical waveguiding, enzymatic catalysis, and biomedicine. We hope this review can promote the understanding and development of metabolite materials to meet functional requirements.

Authors: Roberts Emma , Shirlow Alex , Cox Alistair , Davies Owen 
Published: September 2022

AbstractA 10‐year‐old, entire male, English Springer Spaniel was referred for evaluation of weight loss, polyuria, polydipsia and gastrointestinal tract signs including melena/haematochezia for the previous six months. Results of serum protein electrophoresis, urine analysis, computed tomography of the thorax/abdomen, bone marrow aspiration and core biopsy, and splenic and mesenteric lymph node cytology were consistent with multiple myeloma. Endoscopically obtained gastrointestinal tract biopsies identified marked plasma cell infiltration within the duodenum, ileum and colon; immunohistochemistry showed positive labelling to MUM1 and Lambda confirming clonal plasma cell involvement. The dog entered complete clinical remission seven weeks after starting a melphalan/prednisolone protocol. The dog was euthanised 475 days after starting treatment due to cervical pain and collapse. At the time of euthanasia, blood work was not supportive of a relapse of multiple myeloma. To the authors’ knowledge, this is the first report of multiple myeloma involving the gastrointestinal tract in a dog.
Pre‐operative management of paroxysmal ventricular tachycardia in a stallion scheduled for castration
Authors: Gerardo Citarella , Bettschart‐Wolfensberger Regula 
Published: September 2022

AbstractA 15‐year‐old, fractious, weighing 470 kg, Achal‐Tekkiner stallion was referred for elective castration. Pre‐anaesthetic clinical evaluation revealed tachycardia with a heart rate (HR) of 66 bpm and diastolic left side heart murmur II/VI grade. Lung auscultation was unremarkable. Acepromazine (0.03 mg/kg) was administered intramuscularly to calm the horse for reassessment. Thirty minutes later, HR was 120 bpm. An electrocardiogram (ECG) showed monomorphic ventricular tachycardia. A bolus of Ringer lactate, 10 ml/kg over 30 minutes, and magnesium, 27 g diluted in 1 L 0.9% sodium chloride (NaCl), was administered intravenously. As arrhythmia persisted, a constant‐rate infusion of lidocaine, 50 mcg/kg/h, was started. The horse was monitored with telemetry ECG. The arrhythmia resolved after 24 hours and echocardiography showed mild tricuspid, aortic and pulmonary insufficiency. Anaesthetic risk was considered to be acceptable and the procedure was performed without complications. The horse was discharged after another 24 hours without detectable ECG abnormalities.
The Unconventional Cadmium Borosulfates Cd[B2O(SO4)3] and Cd4[B2O(SO4)6]
Authors: Hämmer Matthias , Höppe Henning A. 
Published: September 2022

AbstractBorosulfates are an expanding class of silicate‐analogous materials. We report the syntheses and crystal structures of two unconventional cadmium borosulfates. Cd[B2O(SO4)3] crystallises in a new structure type in space group Pnma (no. 62, a=896.92(8), b=1152.0(1), c=872.75(8) pm, 1380 refl., 94 ref. param., wR2=0.112). Cd4[B2O(SO4)6] adapts the α‐Mg4[B2O(SO4)6]‐type structure with space group P
(no. 147, a=822.22(4), c=797.88(5) pm, 1810 refl., 58 ref. param., wR2=0.078). Together with simultaneously elsewhere reported conventional phyllosilicate‐analogous Cd[B2(SO4)4], there are now in total three cadmium borosulfates with differing dimensionality of their anions, i. e. 0D, 1D and 2D. These results highlight the special position of cadmium in the periodic table and the ambiguity of its behaviour as main group or transition metal when comparing to other analogous or related borosulfates. The [B2O(SO4)3]2− and [B2O(SO4)6]8− anions are known from other main group and transition metal borosulfates. However, Cd2+ is the first cation for which borosulfates comprising both anions are reported for the same cation. Moreover, the optical and thermal properties of both compounds are reported using IR and UV‐Vis spectroscopy as well as thermogravimetry. Both unconventional borosulfates were prepared by the thermal decomposition of the conventional borosulfate Cd[B2(SO4)4] pursueing our studies on the complex thermal decomposition behaviour of such borosulfates.

AbstractA new tetrazole ligand, 5‐amino‐2‐isopropenyltetrazole, was prepared by regioselective alkylation of 5‐aminotetrazole with allyl bromide in sulfuric acid followed by dehydrobromination of intermediate 5‐amino‐2‐(1‐bromopropan‐2‐yl)tetrazole. 5‐Amino‐2‐isopropenyltetrazole (L) was found to react with copper(II) chloride to generate complex [CuL2Cl2]n. The ligand and its complex were characterized by single crystal X‐ray and thermal analyses. Complex [CuL2Cl2]n presents 1D coordination polymer, formed at the expense of double chlorido bridges between neighbouring octahedral coordinated CuII cations. Tetrazole ligand acts as monodentate ligand coordinated by CuII cations via the heteroring N4 atoms only. Magnetic studies revealed that the copper(II) ions were weakly antiferromagnetically coupled. Natural bond orbital analysis was performed to explain the structural peculiarities of the ligand. Its basicity and the relative stability of the protonated forms were investigated using MO calculations.
Instanton solutions in open superstring field theory
Authors: Berkovits Nathan , Juliatto Vilson Fabricio , Portugal Ulisses M. 
Published: September 2022

Abstract
Open superstring field theory admits a “hybrid” formulation where N = 1 D = 4 supersymmetry is manifest for Calabi-Yau compactifications to four dimensions. Using this formulation, the half-BPS instanton solution of four-dimensional super-Yang-Mills can be easily generalized to the full open superstring field theory. In this paper, we compute the first stringy correction to the super-Yang-Mills instanton solution which involves turning on certain fields at the first massive level.
Entanglement between two evaporating black holes
Authors: Miyata Akihiro , Ugajin Tomonori 
Published: September 2022

Abstract
We study a thermo-field double type entangle state on two disjoint gravitating universes, say A and B, with an eternal black hole on each. As was shown previously, its entanglement entropy of the universe A is computed by the generalized entropy on a new spacetime constructed by suitably gluing the black holes on A and B. We study such spacetime gluings when universes are asymptotically flat and AdS cases, especially when the masses of these black holes are different. We also clarify the rule to construct such a glued spacetime in more general settings from the gravitational path integral view point.

Published: September 2022

Abstract
Purpose
A variety of reconstruction techniques exist for the operative treatment of a ruptured acromioclavicular and coracoclavicular ligamentous complex. However, the complication rate remains high; between 5 and 89%.
The intraoperative distance between the clavicle, acromion and coracoid is important for the refixation quality. In this study, the influence of scapular deflection on coracoclavicular and acromioclavicular distances was analysed.

Methods
The ligamentous insertions of 24 fresh-frozen human scapulae were exposed. The coracoclavicular and acromioclavicular ligaments were referenced and captured in a rigid body system using a three-dimensional (3D) measurement arm. The inferior angle of the scapula was manually pulled into maximum anterior and posterior deflection, simulating a patient positioning with or without dorsal scapular support, respectively. Based on the rigid body system, the distances between the ligamentous insertions were calculated. Statistical evaluation was performed by setting the distances in anterior deflection to 100% and considering the other distances relative to this position.

Results
The scapular deflection had a considerable impact on the distance between the ligamentous insertions. Concerning the conoid ligament, the mean distance was almost doubled when the inferior angle pointed posteriorly compared to anterior deflection (195.3 vs 100.0%; p = 0.028). The insertion of the acromioclavicular capsule also showed a significant association with the direction of deflection (posterior = 116.1% vs. anterior = 100%; p = 0.008).

Conclusion
Dorsal support shifting the inferior angle of the scapula anteriorly reduces the distance between the ligamentous insertions. Therefore, a patient position on a shoulder table with posterior support of the scapula is recommended to reliability reduce the acromioclavicular joint.
Semi-supervised learning for quality control of high-value wood products
Authors: Schubert Mark , Sonderegger Walter , Luković Mirko , Kläusler Oliver 
Published: September 2022

AbstractThe quality control of wood products is often only checked at the end of the production process so that countermeasures can only be taken with a time delay in the event of fluctuations in product quality. This often leads to unnecessary and cost-intensive rejects. Furthermore, since quality control often requires additional procedural steps to be performed by a skilled worker, testing is time-consuming and costly. While traditional machine learning (ML) methods based on supervised learning have been used in the field with some success, the limited availability of labeled data is the major hurdle for further improving model performance. In the present study, the potential of enhancing the performance of the ML methods random forest (RF) and support vector machines (SVM) for quality classification by using semi-supervised learning (SSL) was investigated. Labeled and unlabeled data were provided by Swiss Wood Solutions AG, which produces densified wood for high-value wood products such as musical instruments. The developed approach includes labeling of the unlabeled data using SSL, training and 10k cross-validation of the ML algorithms RF and SVM, and determining the generalization ability using the hold-out test set. Based on the evaluation indices such as accuracy, F1-score, recall, false-positive-rate and confusion matrices, it was shown that SSL could enhance the prediction performance of the quality classification of ML models compared to the conventional supervised learning method. Despite having a small dataset, the work paves the way for future applications of SSL for wood quality assessment.

AbstractParkinson’s disease (PD) is a movement disorder characterized by the early loss of nigrostriatal dopaminergic pathways producing significant network changes impacting motor coordination. Recently three motor stages of PD have been proposed (a silent period when nigrostriatal loss begins, a prodromal motor period with subtle focal manifestations, and clinical PD) with evidence that motor cortex abnormalities occur to produce clinical PD[8]. We directly assess structural changes in the primary motor cortex and corticospinal tract using parallel analyses of longitudinal clinical and cross-sectional pathological cohorts thought to represent different stages of PD. 18F-FP-CIT positron emission tomography and subtle motor features identified patients with idiopathic rapid-eye-movement sleep behaviour disorder (n = 8) that developed prodromal motor signs of PD. Longitudinal diffusion tensor imaging before and after the development of prodromal motor PD showed higher fractional anisotropy in motor cortex and corticospinal tract compared to controls, indicating adaptive structural changes in motor networks in concert with nigrostriatal dopamine loss. Histological analyses of the white matter underlying the motor cortex showed progressive disorientation of axons with segmental replacement of neurofilaments with α-synuclein, enlargement of myelinating oligodendrocytes and increased density of their precursors. There was no loss of neurons in the motor cortex in early or late pathologically confirmed motor PD compared to controls, although there were early cortical increases in neuronal neurofilament light chain and myelin proteins in association with α-synuclein accumulation. Our results collectively provide evidence of a direct impact of PD on primary motor cortex and its output pathways that begins in the prodromal motor stage of PD with structural changes confirmed in early PD. These adaptive structural changes become considerable as the disease advances potentially contributing to motor PD.
