Published: November 2022

AbstractIn this study, bio-based thermoplastic polyurethane (TPU) for use in soft actuators is bio-based poly(ether-urethane) made using fermented corn, along with bio-derived compounds such as propane-1,3-diol (PDO) as a chain extender. Bio-based TPUs were obtained through a solvent-free one-shot synthesis method, and the effects of varying the [NCO]/[OH] molar ratio and type of isocyanates on chemical structure, thermal stability, and mechanical properties were investigated. The degree of phase separation (DPS) and state of hard segment (HS) / soft segment (SS) of TPU are important factors affecting the thermal and physical properties of the prepared film. These properties depend on the [NCO]/[OH] molar ratio and the type of isocyanates used for polymerization. The results showed that, when aromatic isocyanate was used, the degree of separation of the HS/SS was improved as the molar ratio increased. The average molecular weight and DPS as well as thermal and mechanical properties of 1-isocyanato-4-[(4-isocyanatophenyl)methyl]benzene (MDI)-based TPU samples are all higher than those of 1,1’-methylenebis(4-isocyanatocyclohexane) (H12MDI)-based TPU samples in spite of the lower HS content. These findings of this study are expected to contribute to the preparation of fused deposition modeling (FDM) 3D printing or 4D printing for shape memory polymer from bio-based TPU filaments for use in soft actuators with a shore hardness range of 59~84A.
Facial expression recognition based on improved depthwise separable convolutional network
Authors: Huo Hua , Yu YaLi , Liu ZhongHua 
Published: November 2022

AbstractA single network model can’t extract more complex and rich effective features. Meanwhile, the network structure is usually huge, and there are many parameters and consume more space resources, etc. Therefore, the combination of multiple network models to extract complementary features has attracted extensive attention. In order to solve the problems existing in the prior art that the network model can’t extract high spatial depth features, redundant network structure parameters, and weak generalization ability, this paper adopts two models of Xception module and inverted residual structure to build the neural network. Based on this, a face expression recognition method based on improved depthwise separable convolutional network is proposed in the paper. Firstly, Gaussian filtering is performed by Canny operator to remove noise, and combined with two original pixel feature maps to form a three-channel image. Secondly, the inverted residual structure of MobileNetV2 model is introduced into the network structure. Finally, the extracted features are classified by Softmax classifier, and the entire network model uses ReLU6 as the nonlinear activation function. The experimental results show that the recognition rate is 70.76% in Fer2013 dataset (facial expression recognition 2013) and 97.92% in CK+ dataset (extended Cohn Kanade). It can be seen that this method not only effectively mines the deeper and more abstract features of the image, but also prevents network over-fitting and improves the generalization ability.

Published: November 2022

AbstractLilium candidum L. is a plant with rich cultural traditions and huge potential in floriculture and modern medicine. Our study analyzed the effects of light emitting diodes (LEDs) of variable quality on adventitious organogenesis induced in bulb scales placed on Murashige and Skoog medium. In addition to the spectral compositions of red (100%), blue (100%), and red and blue light (RB ratio 7:3), RB light was mixed in equal proportions (50%) with green (RBG), yellow (RBY), UV (RBUV), and far red (RBfR) light. We also tested white LED (Wled). Fluorescent lamp light (Fl) and darkness (D) served as controls. We assessed the effects of light on the morphometric features as well as the physiological and biochemical quality of the bulblets (adventitious bulbs). Bulb formation was observed under all light qualities, even in darkness, albeit to a limited extent. White LED light (Wled) treatment translated into the highest efficiency of bulblet formation and the greatest number of bulbs with developed leaves. The leaves, even though the shortest ones, also developed as a result of RBG treatment, and this light mixture enhanced the diameter of the forming bulblets. The bulbletsunder this light spectrum accumulated the most chlorophyll and carotenoids. The bulblets formed under B, RBfR and RBG LED had more than two times higher phenoliclevels than those formed under R LED and Fl. The bulbletsformed under B LED were the richest in soluble sugars, similarly to those developing in darkness (D).
A novel DEM-based pore-scale thermal-hydro-mechanical model for fractured non-saturated porous materials
Authors: Krzaczek M. , Nitka M. , Tejchman J. 
Published: November 2022

AbstractFor fracture propagation, a novel DEM-based pore-scale thermal-hydro-mechanical model of two-phase fluid flow with heat transfer in non-saturated porous materials with low porosity was developed. Numerical computations were performed for bonded granular specimens, using a DEM fully coupled with CFD (based on a fluid flow network) and heat transfer, which integrated discrete mechanics with fluid mechanics and heat transfer at the meso-scale. Both the fluid (diffusion and advection) and bonded particles (conduction) were involved in heat transfer. The numerical findings of the coupled thermal-hydraulic-mechanical (THM) model were first compared to the analytical solution of the classic 1D heat transport problem. The numerical and analytical outcomes were in perfect agreement. Advection's impacts on the cooling of a bonded particle assembly were next numerically demonstrated for low and high Peclet numbers. Finally, the THM model's utility was proved in a thermal contraction test employing a bonded particle assembly during cooling, which resulted in the creation of a macro-crack. The effects of a macro-crack on the distribution of fluid pressure, density, velocity, and temperature were studied.

Abstract
Introduction
Practicing endoscopic procedures is fundamental for the education of clinicians and the benefit of patients. Despite a diverse variety of model types, there is no system simulating anatomical restrictions and variations in a flexible and atraumatic way. Our goal was to develop and validate a new modelling approach for adhesion forces between colon and abdominal wall.

Methods
An inlay for a standard mechanical trainer was designed and 3D printed. Colon specimens were fixed to the inlay along colon ascendens (CA) and colon descendens (CD) by a vacuum. Our system, which we refer to as Colonoscopy Vacuum Model (CoVaMo), was validated with 11 test persons with varying level of expertise. Each performed one colonoscopy and one polypectomy in the CoVaMo and in the Endoscopic Laparoscopic Interdisciplinary Training Entity (ELITE). Achieved adhesion forces, times required to fulfill different tasks endoscopically and a questionnaire, assessing proximity to reality, were recorded.

Results
Mean adhesion forces of 37 ± 7 N at the CA and 30 ± 15 N at the CD were achieved. Test subjects considered CoVaMo more realistic than ELITE concerning endoscope handling and the overall anatomy. Participants needed statistically significantly more time to maneuver from anus to flexura sinistra in CoVaMo (377 s ± 244 s) than in ELITE (58 s ± 49 s).

Conclusion
We developed a training environment enabling anatomically and procedural realistic colonoscopy training requiring participants to handle all endoscope features in parallel. Fixation forces compare to forces needed to tear pig colon off the mesentery. Workflow and inlay can be adapted to any arbitrary ex vivo simulator.
Multilevel and multifaceted brain response features in spiking, ERP and ERD: experimental observation and simultaneous generation in a neuronal network model with excitation–inhibition balance
Authors: Ouyang Guang , Wang Shengjun , Liu Mianxin , Zhang Mingsha , Zhou Changsong 
Published: November 2022

AbstractBrain as a dynamic system responds to stimulations with specific patterns affected by its inherent ongoing dynamics. The patterns are manifested across different levels of organization—from spiking activity of neurons to collective oscillations in local field potential (LFP) and electroencephalogram (EEG). The multilevel and multifaceted response activities show patterns seemingly distinct and non-comparable from each other, but they should be coherently related because they are generated from the same underlying neural dynamic system. A coherent understanding of the interrelationships between different levels/aspects of activity features is important for understanding the complex brain functions. Here, based on analysis of data from human EEG, monkey LFP and neuronal spiking, we demonstrated that the brain response activities from different levels of neural system are highly coherent: the external stimulus simultaneously generated event-related potentials, event-related desynchronization, and variation in neuronal spiking activities that precisely match with each other in the temporal unfolding. Based on a biologically plausible but generic network of conductance-based integrate-and-fire excitatory and inhibitory neurons with dense connections, we showed that the multiple key features can be simultaneously produced at critical dynamical regimes supported by excitation–inhibition (E–I) balance. The elucidation of the inherent coherency of various neural response activities and demonstration of a simple dynamical neural circuit system having the ability to simultaneously produce multiple features suggest the plausibility of understanding high-level brain function and cognition from elementary and generic neuronal dynamics.
Trustworthiness of voice-based assistants: integrating interlocutor and intermediary predictors
Authors: Weidmüller Lisa , Etzrodt Katrin , Engesser Sven 
Published: November 2022

AbstractWhen intelligent voice-based assistants (VBAs) present news, they simultaneously act as interlocutors and intermediaries, enabling direct and mediated communication. Hence, this study discusses and investigates empirically how interlocutor and intermediary predictors affect an assessment that is relevant for both: trustworthiness. We conducted a secondary analysis using data from two online surveys in which participants (N = 1288) had seven quasi-interactions with either Alexa or Google Assistant and calculated hierarchical regression analyses. Results show that (1) interlocutor and intermediary predictors influence people’s trustworthiness assessments when VBAs act as news presenters, and (2) that different trustworthiness dimensions are affected differently: The intermediary predictors (information credibility; company reputation) were more important for the cognition-based trustworthiness dimensions integrity and competence. In contrast, intermediary and interlocutor predictors (ontological classification; source attribution) were almost equally important for the affect-based trustworthiness dimension benevolence.

Authors: Oochit Krishna K. , Shahwan Safwan , Hughes James , Kourounis Georgios 
Published: November 2022

Abstract
Background and Aims
Bariatric surgery is an effective treatment for obesity. Though both short- and long-term outcomes have been reported, most of the published literature reports on short-term outcomes. Identification of post-operative weight regain and re-emergence of comorbidities requires medium- and long-term follow-up. We aimed to identify the distribution of follow-up times within the literature.

Methods
We screened through 1807 articles from 9 PubMed Indexed bariatric surgery journals published between January to June of 2015 and 2021 and selected articles reporting weight loss as a main outcome. Follow-up intervals were defined as per American Society for Metabolic and Bariatric Surgery (ASMBS) guidelines.

Results
Fifty-three and sixty-three articles were identified in 2015 and 2021 respectively. Reported follow-up lengths in 2015 were 60% short-, 26% medium-, and 14% long-term; while in 2021, there were 65% short-, 10% medium-, and 25% long-term articles. Of the articles reporting long-term outcomes in 2015 and 2021, 48%, and 70% of the included patients respectively had > 5 years follow-up.

Conclusion
Though reporting of long-term outcomes increased, most published outcomes remain short-term. The UK National Bariatric Surgery Registry is helping to mitigate this. An increased effort and emphasis on reporting long-term outcomes is needed.

Digitalization?A Matter of Trust: A Double-Mediation Model Investigating Employee Trust in Management Regarding Digitalization
Authors: Lau Angelika , Höyng Mona 
Published: November 2022

AbstractThe purpose of this paper is to determine how employee trust in management regarding digitalization (TMD) is encouraged to successfully promote technological change linked to digitalization and implement digital technologies within organizations. TMD is considered a necessary precondition for employee cooperation regarding the successful implementation of digitalization within organizations. Derived from existing theoretical and empirical research on trust, a double-mediation model is developed. The proposed model investigates the direct relationships between strong digital vision (SDV), leader-member exchange (LMX), and perceptions of organizational politics (POP) on employee TMD. Further, the mediating roles of LMX and POP are investigated regarding the relationship between SDV and TMD. Based on data collected from 1,145 employees of an internationally operating energy supplier, significant positive relationships between SDV, LMX, POP, and employee TMD were found. Further, the results confirmed that LMX and POP sequentially double-mediated the relationship between SDV and TMD. Consequently, by developing a theoretical model for the specific context of digitalization, this study contributes to theory development concerning employee TMD. Furthermore, this study provides practical implications for management in terms of identifying institutional aspects within organizations that enhance TMD in the digital labor context.
The Dynamic Interplay of Healthy Lifestyle Behaviors for Cardiovascular Health
Authors: Kris-Etherton Penny M. , Sapp Philip A. , Riley Terrance M. , Davis Kristin M. , Hart Tricia , Lawler Olivia 
Published: November 2022

Abstract
Purpose of Review
The recent rise in cardiovascular disease (CVD) deaths in the USA has sparked interest in identifying and implementing effective strategies to reverse this trend. Healthy lifestyle behaviors (i.e., healthy diet, regular physical activity, achieve and maintain a healthy weight, avoid tobacco exposure, good quality sleep, avoiding and managing stress) are the cornerstone for CVD prevention.

Recent Findings
Achieving all of these behaviors significantly benefits heart health; however, even small changes lower CVD risk. Moreover, there is interplay among healthy lifestyle behaviors where changing one may result in concomitant changes in another behavior. In contrast, the presence of one or more unhealthy lifestyle behaviors may attenuate changing another lifestyle behavior(s) (poor diet, inadequate physical activity, overweight/obesity, poor sleep quality, tobacco exposure, and poor stress management).

Summary
It is important to assess all of these lifestyle behaviors with patients to plan an intervention program that is best positioned for adherence.
Childhood Socioeconomic Status and Late-Adulthood Health Outcomes in China: A Life-Course Perspective
Authors: Zhou Tao , Harris Richard , Manley David 
Published: November 2022

AbstractThe relationship between socioeconomic status and health has been studied widely across many western countries but the relationship is relatively underexplored in China. Using a life-course perspective, this paper examines the associations between six indicators of childhood socioeconomic status with classic late-adulthood health outcomes. The analysis uses logistic and Ordinary Least Square (OLS) regression models with data on life history and data from the most recent wave of CHARLS – a nationally representative survey of people aged 45 and older. The models demonstrate that unfavourable socioeconomic status in childhood is, in general, correlated with poorer health outcomes later in life, whereas a more socioeconomically advantaged childhood is associated with better health outcomes in middle and older age. However, for those individuals who were overweight in childhood, the advantaged socioeconomic status effect appears to increase the probability of remaining overweight when older. Furthermore, the indicators of current socioeconomic status as well as the interaction terms between childhood socioeconomic status and adulthood socioeconomic status were introduced, as most existing research in the world, including China, tends to only focus on the mediation effect of current socioeconomic status. The findings show that, among all the health outcomes in this research, only the associations between disability-related health variables and adulthood socioeconomic status are moderated by childhood socioeconomic status. These results indicate both homogeneity and heterogeneity in the impacts of childhood socioeconomic status on different health outcomes and also inform public policies in China with regard to population health.

AbstractBackgroundPerineural invasion (PNI) is associated with metastasis in malignancies, including intrahepatic cholangiocarcinoma (ICC), and is correlated with poor prognosis.MethodsThe study included three large cohorts: ZS-ICC and TMA cohorts from our team, MSK cohort from a public database, and a small cohort named cohort 4. Prognostic implications of PNI were investigated in MSK cohort and TMA cohort. PNI-related genomic and transcriptomic profiles were analyzed in MSK and ZS-ICC cohorts. GO, KEGG, and ssGSEA analyses were performed. Immunohistochemistry was used to investigate the relationship between PNI and markers of neurons, hydrolases, and immune cells. The efficacy of adjuvant therapy in ICC patients with PNI was also assessed.ResultsA total of 30.6% and 20.7% ICC patients had PNI in MSK and TMA cohorts respectively. Patients with PNI presented with malignant phenotypes such as high CA19-9, the large bile duct type, lymph node invasion, and shortened overall survival (OS) and relapse-free survival (RFS). Nerves involved in PNI positively express tyrosine hydroxylase (TH), a marker of sympathetic nerves. Patients with PNI showed high mutation frequency of KRAS and an immune suppressive metastasis prone niche of decreased NK cell, increased neutrophil, and elevated PD-L1, CD80, and CD86 expression. Patients with PNI had an extended OS after adjuvant therapy with TEGIO, GEMOX, or capecitabine.ConclusionOur study deciphered the genomic features and the immune suppressive metastasis-prone niche in ICC with PNI. Patients with PNI showed a poor prognosis after surgery but a good response to adjuvant chemotherapy.Graphical abstract
Dynamic shielding to secure multi-hop communications in vehicular platoons
Authors: Yang Yiran , Liu Xiqing , Wang Zhifeng , Liu Yiliang 
Published: November 2022

AbstractVehicular platoons are among the most advanced driving assistance systems that may generate considerable fuel savings and increase traffic efficiency. However, communication between vehicles in a platoon is always vulnerable to eavesdropping due to the broadcast nature of wireless channels. To address this issue, we investigate security issues from the physical layer perspective for multi-hop vehicular platooning. The dynamic shielding secured transmission scheme is proposed to guarantee the confidential transmission of private information. Specifically, the neighboring vehicles can alternately act as friendly shielders, which transmit jamming signals to interfere with the eavesdroppers without knowing the channel state information, and thus the secrecy capacity would increase. The mathematical derivation of secrecy capacity is obtained for performance analysis. Meanwhile, the numerical results verify the properties, efficiency, and adaptability of the proposed scheme.
The Discursive Construction of Polyamory: Legitimising an Alternative to Monogamy
Authors: Montali Lorenzo , Frigerio Alessandra , Spina Federica , Zulato Edoardo 
Published: November 2022

AbstractPolyamory is an umbrella term denoting the practice of having multiple romantic and intimate relationships with the consent of everyone involved. Within a mononormative culture, becoming polyamorous may be associated with uncertainty and a feeling of being suspended. Moreover, the preferential attitude towards monogamy marginalises polyamory as indecent and corrupt, creating feelings of shame and social isolation. Our research explored the discursive construction of polyamory in Italy by identifying the strategies used to deal with such identity construction and social recognition issues. We conducted 15 semistructured interviews with people who defined themselves as polyamorous. Our discourse analysis identified a narrative that overturns the dominant hegemonic perspective; this narrative presented monogamy as a practice generating difficulties and problems and polyamory as a thoroughly satisfying and adequate relational modality. This narrative was constructed using six discursive strategies, allowing participants to achieve three discursive purposes. By naturalising polyamory and constructing it as a stable trait, participants essentialised polyamory; by providing a normative definition of polyamory and identifying with the polyamorous community, they set up the boundaries of polyamory; finally, by moralising polyamory and attributing transformative power to it, they valorised polyamory. Overall, the definition of a polyamorous order allows for the integration of polyamory into one’s life, even if polyamorists remain a minority group trapped in the public liminality brought about by a mononormative culture.
