AbstractDrawing inspiration for biomaterials from biological systems has led to many biomedical innovations. One notable bioinspired device, Velcro, consists of two substrates with interlocking ability. Generating reversibly interlocking biomaterials is an area of investigation, as such devices can allow for modular tissue engineering, reversibly interlocking biomaterial interfaces, or friction‐based coupling devices. Here, a biaxially interlocking interface generated using electrostatic flocking is reported. Two electrostatically flocked substrates are mechanically and reversibly interlocked with the ability to resist shearing and compression forces. An initial high‐throughput screen of polyamide flock fibers with varying diameters and fiber lengths is conducted to elucidate the roles of different fiber parameters on scaffold mechanical properties. After determining the most desirable parameters via weight scoring, polylactic acid (PLA) fibers are used to emulate the ideal scaffold for in vitro use. PLA flocked scaffolds are populated with osteoblasts and interlocked. Interlocked flocked scaffolds improved cell survivorship under mechanical compression and sustained cell viability and proliferation. Additionally, the compression and shearing resistance of cell‐seeded interlocking interfaces increased with increasing extracellular matrix deposition. The introduction of extracellular matrix‐reinforced interlocking interfaces may serve as binders for modular tissue engineering, act as scaffolds for engineering tissue interfaces, or enable friction‐based couplers for biomedical applications.

AbstractUsing energy‐saving electrochromic (EC) displays in smart devices for augmented reality makes cost‐effective, easily producible, and efficiently operable devices for specific applications possible. Prussian blue (PB) is a metal‐organic coordinated compound with unique EC properties that limit EC display applications due to the difficulty in PB micro‐patterning. This work presents a novel micro‐printing strategy for PB patterns using localized crystallization of FeFe(CN)6 on a substrate confined by the acidic‐ferric‐ferricyanide ink meniscus, followed by thermal reduction at 120 °C, thereby forming PB. Uniform PB patterns can be obtained by manipulating printing parameters, such as the concentration of FeCl3·K3Fe(CN)6, printing speed, and pipette inner diameter. Using a 0.1 M KCl (pH 4) electrolyte, the printed PB pattern is consistently and reversibly converted to Prussian white (CV potential range: −0.2–0.5 V) with 200 CV cycles. The PB‐based EC display with a navigation function integrated into a smart contact lens is able to display directions to a destination to a user by receiving GPS coordinates in real time. This facile method for forming PB micro‐patterns could be used for advanced EC displays and various functional devices.

AbstractDevelopment of more sustainable and environmentally friendly polymers as alternatives to petroleum‐based polymers is a priority. We report the synthesis of six linear, aliphatic, renewable polymers by acyclic diene metathesis (ADMET) and thiol‐ene polymerization of α,ω‐polyenes resulting from thermal esterification of adipic, azelaic, and itaconic acids with 9‐decen‐1‐ol. ADMET homopolymerization was performed with 1.0 mol% Hoveyda–Grubbs second generation metathesis catalyst. Thiol‐ene copolymerization was conducted photochemically with 1 wt% 2,2‐dimethoxy‐2‐phenyl‐acetophenone and stoichiometric 1,2‐ethanedithiol (EDT). Although the thiol‐ene copolymers exhibited carbon and atom economies of 100%, the ADMET‐derived polyesters possessed superior renewable carbon content (100%) and environmental factors (<4). These results were attributed to incorporation of non‐renewable EDT into poly(thioether‐ester)s and loss of ethene during production of ADMET polyesters. The Mn (>26 kDa), Mw (>92 kDa), and dispersities (>3.4) of the poly(thioether‐ester)s were higher than the corresponding polyesters, which in part explained why the poly(thioether‐ester)s gave higher melting (>61°C), crystallization (>49°C) and glass transition (>−31°C) temperatures. The cross‐linked itaconate polymers did not melt or crystallize, thereby suggesting amorphous morphology. Lastly, the ADMET polyesters were more thermally stable (T50 > 408°C) than the poly(thioether‐ester)s (T50 < 377°C). In summary, the aliphatic biopolymers displayed a wide range of properties that were impacted by polymerization method as well as the nature of the monomer.

Published: November 2022

AbstractTo solve the security problem of industrial cyber‐physical systems (ICPS) suffering from the Denial of Service (DoS) attack, this paper proposes an optimal control strategy with functions of tracking and compensation control. The system model, being depicted as a discrete linear time‐invariant system combined with an improved Bernoulli model, is established to describe the system under DoS attacks by using the feedback control theory. The optimal control strategy is completed by designing linear quadratic Gaussian (LQG) controller consisting of a tracking regulator and a Kalman filter to achieve tracking control of ICPS whose equilibrium state is neither zero state nor zero output, where a periodic event‐triggered mechanism is adopted for ensuring the system's stability. The compensation control strategy is completed by designing a compensator to compensate the system to a certain extent through the multistep state prediction compensation strategy after a DoS attack being detected, where the detector is adopted to detect the DoS attack based on the measurement residual obtained by the Kalman filter. The simulation test is conducted by using Simulink/True Time tool with a ball‐beam system as the physical object, whose results show that the tracking regulator can achieve the tracking control of ICPS; compensation strategy can reduce the impact of the attack on the system to a certain extent.
Nuclei and tracts in the pretectum and associated tegmentum of crocodiles
Authors: Pritz Michael B. 
Published: November 2022

AbstractIn all vertebrates, the pretectum and associated tegmentum arise from prosomere 1, but the adult derivatives of these embryonic regions are not well defined in reptiles—especially in crocodiles, the reptilian group most closely related to birds. Despite its importance in vision and visuomotor behavior, descriptions of the pretectum in crocodiles are brief and photographs are lacking. To fill this gap in knowledge, the pretectum and associated tegmentum were examined in two crocodilians, Caiman crocodilus and Alligator mississippiensis, using a variety of histological stains in all three traditional planes of section. These observations were compared with similar studies in other reptiles and birds. These comparisons were hampered by differences in nomenclature and limited data. Nevertheless, pretectal nuclei in receipt of retinal input in crocodiles, other reptiles, and birds were the most easily identified when compared with the present analysis. Despite identifying the traditional nuclei comprising the pretectum of crocodiles, other areas remain to be characterized. Nevertheless, knowledge gained from this description will aid further investigations of this brain region in crocodiles and other reptiles as well as provide a reference for developmental studies in crocodiles.

AbstractThis work aimed to develop and characterize edible films made with cassava starch and buriti oil in a factorial scheme to verify the effect of the interaction between these factors on the physical properties. The experiment was developed in an entirely randomized design in a 2 × 3 factorial scheme. They were prepared with six different formulations evaluating thickness, water solubility, moisture, water activity, chromaticiy (C*), total color difference (ΔE*), opacity and light transmittance, tensile strength and elongation at break, thermogravimetric analysis, and differential scanning calorimetry. There were effects of each factor on the film properties as well as interaction effects. It was found that with the increase in the concentration of buriti oil, there was a decrease in water solubility, tensile strength, and elongation at break. Higher concentrations of cassava starch increased the thickness and tensile strength. On the other hand, it decreased the moisture content, water solubility, and elongation at break. Transparency, C*, and ΔE* were influenced by the interaction effect between the factors. On the other hand, films with higher oil content showed greater thermal degradation. We conclude that films made with 6% cassava starch and 1% buriti oil present better mechanical and thermal properties with the possibility of application in the food industry.

AbstractThis study reports on performance enhancement of a Cu2ZnSnS4 solar cell introducing Sb2S3 as hole transport layer (HTL) along WS2 as buffer layer. We have investigated photovoltaic (PV) characteristics by utilizing SCAPS‐1D. A comparative analysis on PV performances between conventional CZTS/CdS and proposed Ni/Sb2S3/CZTS/WS2/FTO/Al solar cells is presented. It is revealed that “spike like” band structure at the CZTS/WS2 interface having smaller conduction band offset makes it potential alternative to commonly used CdS buffer. This report also evaluates that the Sb2S3 as an HTL inserted at the rear of CZTS enhances performances by reducing carrier recombination at back interface with appropriate band alignment. The impacts of thickness, carrier concentration of different layers, and bulk defect density in CZTS as well as the interface defects on cell outputs are analyzed. The influences of temperature, work function, and cell resistances are also examined. Optimum absorber thickness of 1.0 μm along doping density of 1017 cm−3 is selected. A maximum efficiency of 30.63% is achieved for the optimized CZTS cell. Therefore, these results suggest that Sb2S3 as HTL and WS2 as buffer layer can be employed effectively to develop highly efficient and low‐cost CZTS solar cells.

Firm's cost of debt firstly changes conservatism and then leads the choices of future diversification strategies: Evidence from Asian countries
Authors: Sumiyana Sumiyana , Usmayanti Vivi 
Published: November 2022

AbstractThis study investigates how firms’ debt cost affects their conservatism in the first stage, and then leads their future strategies in the second stage. Moreover, it shows that firms would likely ignore their conservatism when choosing a strategy, especially diversification. Then, it presents two interrelated novelties. First, firms operate with a low cost of debt, constructing their high conservatism. As a result, they would likely choose a cost‐reduction strategy. Conversely, firms with low conservatism usually choose diversification strategies because they are at the lowest risk. Second, this study highlights that the firms’ diversification strategies are a conundrum while considering the cost of debt and conservatism when applied by firms operating the business in developing countries. Operating in emerging economies, firms could choose a higher debt cost and simultaneously ignore conservatism, maintaining their creditors as funding. Moreover, this research examines Asian countries' data using ordinary least‐square (OLS) and two‐stage last‐square (2‐SLS). In addition, 2‐SLS outperforms in the staged‐associative examinations. Thus, this research reveals that the cost of debt, conservatism and chosen strategies relate to simple staging. As a result, they acquire the highest cost of debt, with the high‐risk level affecting their weighted cost of capital. Finally, this research infers that firms' costs of debt and conservatism are not mutually exclusive and sequentially affect their future strategic choices. It, therefore, suggests that when firms choose diversification strategies, they might probably take a high cost of debt, accompanied by a highly conservative level.

AbstractIntroductionTo investigate the relationship of superoxide dismutase (SOD) and malondialdehyde (MDA) levels with left ventricular geometry (LVG) and function in patients with primary hypertension (PH).MethodsA total of 222 PH patients and 25 healthy control (HC)s were enrolled in this study. All subjects underwent echocardiography and blood biochemical examination. PH patients were divided into four groups based on Ganau classification: normal geometry (NG) group, concentric remodeling (CR) group, eccentric hypertrophy (EH) group, and concentric hypertrophy (CH) group. Pearson correlation analysis and logistic regression analysis were used to analyze the relationship between SOD and MDA with left ventricular structure and function.ResultsCompared to the HC, NG and CR groups, MDA level was higher while SOD level was lower in the EH and CH groups (all P < 0.001). SOD level was negatively correlated with IVSd, LVDd, LVPW, and global longitudinal strain (GLS), but positively correlated with LVEF. MDA level was positively correlated with IVSd, LVPW, and GLS, while negatively correlated with e'/a' and LVEF. SOD and MDA were independently associated with CR (OR = 0.970, P = 0.003; OR = 1.204, P = 0.043), EH (OR = 0.879, P < 0.001; OR = 2.197, P = 0.001) and CH (OR = 0.796, P < 0.001; OR = 3.669, P < 0.001).ConclusionThe SOD and MDA levels were correlated with LVG and function in PH patients. SOD and MDA may be important influencing factors of LVG change.
Didactic and clinical nutrition content in dental hygiene programs: Directors’ perspective
Authors: Onofrietti Stacy L. , Gurenlian JoAnn 
Published: November 2022

AbstractPurposeConcern over inadequacy and implementation processes of nutritional content in dental hygiene education program (DHEP) curriculum policy at both a didactic level and clinical level exists. The purpose of this qualitative study was to examine the DHEP extent and practices of didactic and clinical nutrition content, identify DHEP barriers to increasing nutrition education content, and determine the need for a nutrition content curriculum standard from the director's perspective.MethodsA qualitative descriptive design was utilized, and DHEP directors were recruited through purposive sampling. Interviews were transcribed directly following each interview and data was analyzed simultaneously. The thematic analysis process was a hybrid approach incorporating both the inductive and deductive approaches.ResultsFour major themes emerged from the study: value of nutrition services, power, capacity building expectations, and nutrition curriculum distribution. The directors’ intentions with nutritional content for the DHEP were not consistent with what occurred in implementation. The findings revealed a disconnect in the directors’ ability to implement adequate nutrition curriculum content. The lack of power as the educational leader in the form of decreased autonomy due to policy implications filtered across all interviews. The findings further noted the capacity building expectations needed among DHEPs in the areas of faculty and student calibration.ConclusionsMultiple challenges impact the ability of program directors to implement accurate and adequate didactic and clinical related nutrition content in DHEPs. Future research, including DHEP directors and faculty teaching nutrition courses across the United States, would be beneficial in developing a broader perspective and creating a nutrition model standard.
Inside Zambia's ‘new normal:’ COVID‐19 policy responses and implications for peri‐urban food security and livelihoods
Authors: Manda Simon 
Published: November 2022

AbstractThis paper explores COVID‐19 policy responses and experiences of their impact on food systems and livelihoods, and other factors shaping vulnerability among peri‐urban small‐scale farmers in Zambia. We draw on household surveys and case studies, multi‐level interviews and group discussions to make sense of ‘new normal’ policy (in)action and its (in) effectiveness in shaping peri‐urban production, market linkages and livelihoods during the pandemic. Results show COVID‐19 policy responses affected peri‐urban production supply and demand for food and inputs. The ‘new normal’ policy responses aimed at striking a balance between health concerns and economic development as a pathway to recovery have not been followed by systematic peri‐urban agriculture support, leading to failure to stimulate production and drive urban market linkages, including supermarkets. Findings bring nuance to fragilities in national food systems and the need for long‐term and transformative interventions that can strengthen peri‐urban agriculture and livelihoods beyond the pandemic.

BackgroundReactive stroma is recognized as one of the independent prognostic factors in prostate cancer (PCa). Intravoxel incoherent motion (IVIM) and diffusion kurtosis imaging (DKI) may be useful for assessing the reactive stromal grade (RSG).PurposeTo investigate whether IVIM and DKI models can evaluate RSG in PCa patients.Study TypeRetrospective.SubjectsA total of 56 PCa patients aged 73 years on average confirmed by MRI and transrectal ultrasound (MRI/TRUS) fusion biopsy divided into two subgroups (18 high RSG and 38 low RSG).Field Strength/SequenceA 3 T/T1WI‐fs, T1WI, T2WI‐fs, T2WI, DWI, IVIM, and DKI.AssessmentApparent diffusion coefficient (ADC), pure diffusion coefficient (D), pseudo‐diffusion coefficient (D*), perfusion fraction (f), mean diffusion (MD), mean kurtosis (MK) were obtained. Patients were divided into high RSG PCa (>50% reactive stroma) and low RSG PCa (≤50% reactive stroma) groups on hematoxylin and eosin (H&E) stained sections.Statistical TestsSpearman correlation and independent sample t‐test or Wilcoxon's rank sum test was used to investigate the relationship between each imaging parameter and RSG. The combined parameters were calculated using a binary logistic regression model. Receiver operating characteristic (ROC) analysis was used to explore the value of individual and combined parameters to differentiate between high and low RSG group. Area under the ROC curves (AUC) > 0.7 were used as reference standards.ResultsADC, D, f, and MD values showed positive correlation with RSG (r = 0.489, 0.619, 0.318, and 0.544, respectively); MK showed negative correlation with RSG (r = −0.444). ADC, D, f, and MD values were significantly lower in the low RSG group than in the high RSG group. The combined model showed the best diagnostic ability to differentiate low and high RSG groups (AUC = 0.887).Data ConclusionParameters of IVIM and DKI may be promising methods for assessment of RSG in PCa patients.Evidence Level3.Technical EfficacyStage 3.
