Effect of GNPs and resin blend on tear resistance of 4D printed shape memory photopolymer composite
Authors: Borra N. Dhanunjayarao , Neigapula Venkata Swamy Naidu 
Published: January 2023

Purpose
The tear strength (Ts) is a significant property for any kind of soft polymeric material such as rubber, elastomer, viscoelastic material and its composites, to quantify the suitability of a material for any shape memory applications. Many times, the soft elastomeric polymer material has to be capable enough to deform to a maximum extent of displacement but at the same time, it has to withstand the maximum load without fail. Along with shape recovery properties (i.e. the ability to recover its shape from programmed to the original), the success of the shape memory cycle is mainly depending on its stiffness and strength. It has to resist tear during stretching (i.e. programming stage) as repeatedly subjected to deformation, and, hence, it is important to study the tear behaviour for shape memory polymers (SMPs) and their composites. The purpose of the work is to investigate the effect of parameters on Ts of 4D printed specimen using Taguchi method.

Design/methodology/approach
The objective of the work is to tailor the Ts of SMPs by reinforcing the graphene nano particles (GNPs) in a blended photopolymer (PP) resin with flexible PP and hard PP resin. In this study, a total of nine experiments were designed based on the L9 orthogonal array (OA) using the design of experiments (DOEs). All the shape memory photopolymer composite’s (SMPPCs) specimens are fabricated using masked stereolithography (MSLA), also known as resin three-dimensional printing (R3DP) technique.

Findings
Specimens are tested using universal testing machine (UTM) for maximum tear force (Fmax) and displacement (δ) caused by tearing the specimen to evaluate the strength against the tear. The results showed that the Wt.% of resin blend highly influenced both Fmax and δ, while GNPs also had an impact on δ. The specimens are offering more tear resistance for those specimens blended with less Wt.% of flexible PP at the same time the specimens enable more δ for those specimens reinforced with 0.3 Wt.% GNPs at 10-s exposure time. The optimum combinations are A1, B1 and C3 for the Fmax and Ts and at the same time A1, B3 and C3 for δ.

Research limitations/implications
To customise the tear resistance of SMPPCs using MSLA 3 D printing, this study suggested a blend of PP resins reinforced with GNPs. This opens up a new path for creating novel, inexpensive multi-functional 4-dimensional (4D) printed parts.

Originality/value
The use of flexible PP and hard PP resin blends, fabricating the SMPPCs specimens using 3 D printed MSLA technology, investigating the effect of GNPs, resin blend and exposure time, optimizing the process parameters using Taguchi and the work were all validated using confirmation tests and regression analysis using test train method, which increases the originality and novelty.
Good critical friends are hard to find: promoting peer review among doctoral students
Authors: Tyndall Deborah , Powell Shannon Baker 
Published: January 2023

PurposeThis study aims to examine entry-level PhD students’ experiences with participating in Critical Friends, a peer review protocol, used to support learning the threshold concept of literature review. It also sought to determine if, and how, students used the peer review protocol electively during their first year of doctoral study.Design/methodology/approachThe authors used a sequential, QUAL-qual mixed-method design to guide the study. Reflective learning journals, surveys and interviews were collected from three cohorts of PhD students (N = 18).FindingsThematic analysis revealed that giving and receiving writing critique was uncomfortable for these novice peer reviewers and many described emotional disciplining associated with vulnerability. Critical Friends offered a safe space to begin mastery of the literature review and begin transforming new researcher and writer identities. While Critical Friends was a positive experience for students, they struggled implementing the protocol on their own following the course.Practical implicationsThese findings support the need for faculty to embed peer review opportunities in courses during the first year to facilitate role modeling and mentoring. The findings also demonstrate the need to engage students with peer review early in the program to increase comfort, cultivate student resiliency for accepting critical feedback and build capacity for students to learn with and from others.Originality/valueThis paper advocates for the use of peer review practices early in the doctoral study to promote the development of researcher identity and positioning within the research community.

AbstractPurposeThere is a lack of adjudicated and prospectively randomized published outcomes on the use of drug‐coated balloons (DCB) to treat dysfunctional arteriovenous fistula in Asian patients. This post hoc subgroup analysis of 112 Japanese participants from the global IN.PACT AV Access trial reports outcomes through 12 months.Materials and MethodsParticipants were treated with DCB (n = 58) or standard non‐coated percutaneous transluminal angioplasty (PTA) balloons (n = 54). Outcomes included target lesion primary patency (TLPP), access circuit primary patency, and safety.ResultsThrough 6 months, TLPP was 86.0% (49/57) in the DCB group and 49.1% (26/53) in the PTA group (p < 0.001). Through 12 months, TLPP was 67.3% (37/55) in the DCB group and 43.4% (23/53) in the PTA group (p = 0.013).ConclusionIn this post hoc analysis of Japanese participants from the IN.PACT AV Access trial, participants treated with DCB had higher TLPP through 6 and 12 months compared with PTA.

AbstractBlaps rhynchopetera (Coleoptera: Tenebrionidae) is a beetle that is widely used in folk medicine in Southwest China. The defensive glands of B. rhynchopetera secrete a complex mixture of defensive fluids, which are invaluable sources of bioactive substances for potential biotechnological applications. To provide broader insight into the genetic and biochemical basis of these defensive secretions, we performed RNA sequencing and transcriptome analysis on the defensive glands of B. rhynchopetera. We also identified differentially expressed genes (DEGs) in the defensive gland tissue using selected muscle tissue as a control. We then performed GO and KEGG enrichment analysis on the DEGs to analyze expression patterns characteristic of the defensive glands. In total, we obtained 283,921,912 high‐quality clean reads, which we assembled into 39,735 transcripts with a mean length of 1,300.94 bp. These transcripts were then assembled into 27,104 unigenes with an average length of 1,143.05 bp. DEG analysis showed that 1,666 genes were significantly up‐regulated and 2,565 genes were significantly down‐regulated in defense gland tissues. GO enrichment analysis of these DEGs revealed that most genes were enriched in GO terms related to substance metabolism and transport. KEGG pathway enrichment results showed that lysosome‐related pathways were the most highly enriched in DEGs, while many pathways related to specific metabolic pathways—such as N‐glycan biosynthesis and insect hormone biosynthesis—were significantly up‐regulated. Finally, it is also important to note that most GO terms related to pathogen defense as well as genes enriched in associated KEGG pathways were also significantly down‐regulated in defensive gland tissue.
Recent advances in producing food additive L‐malate: Chassis, substrate, pathway, fermentation regulation and application
Authors: Ding Qiang , Ye Chao 
Published: January 2023

AbstractIn addition to being an important intermediate in the TCA cycle, L‐malate is also widely used in the chemical and beverage industries. Due to the resulting high demand, numerous studies investigated chemical methods to synthesize L‐malate from petrochemical resources, but such approaches are hampered by complex downstream processing and environmental pollution. Accordingly, there is an urgent need to develop microbial methods for environmentally‐friendly and economical L‐malate biosynthesis. The rapid progress and understanding of DNA manipulation, cell physiology, and cell metabolism can improve industrial L‐malate biosynthesis by applying intelligent biochemical strategies and advanced synthetic biology tools. In this paper, we mainly focused on biotechnological approaches for enhancing L‐malate synthesis, encompassing the microbial chassis, substrate utilization, synthesis pathway, fermentation regulation, and industrial application. This review emphasizes the application of novel metabolic engineering strategies and synthetic biology tools combined with a deep understanding of microbial physiology to improve industrial L‐malate biosynthesis in the future.

Published: January 2023

AbstractData limitations often challenge the reliability of water quality models, especially in intensively managed watersheds. While numerous studies report successful hydrological model setup and calibration, few have addressed in detail the data challenges for multisite and multivariable model calibration to an intensively managed watershed. In this study, we address some of these challenges based on our reflective experience calibrating the Soil and Water Assessment Tool (SWAT) to the Upper Sangamon River Watershed in central Illinois based on daily flow, annual crop yield, and monthly sediment, nitrate, and total phosphorus loads. We highlight some challenges in SWAT calibration processes due to data errors and inconsistencies, and insufficient precipitation and water quality observations. Following, we demonstrate the merits of additional weather and water quality observations that could help reduce input uncertainties, and we provide suggestions for selecting appropriate observations for the model calibration. After dealing with the data issues, we show that the SWAT model could be calibrated with acceptable results for the case study watershed.
How convergent are rice export prices in the international market?
Authors: A. Valera Harold Glenn , J. Holmes Mark , Pede Valerien O. , Balié Jean 
Published: January 2023

AbstractThis study revisits the issue of long‐term price convergence of rice export prices for India, Pakistan, Thailand, Uruguay, the United States, and Vietnam using a two‐stage pairwise unit root testing approach. To deduce evidence or lack of proof of convergence in price series, we also examine convergence using sigma and beta convergence specified in both unconditional and conditional frameworks. The methodology used is driven by the need to address three key concerns: (i) the likelihood of finding stationary price differentials, (ii) the magnitude of these differentials, and (iii) their speed of adjustment. To evaluate these concerns, we use monthly data for 18 price series drawn from these six countries from September 2011 to February 2021. The evidence points to a lack of international convergence. This gives rise to the possibility that a shield from a general downward export price trend is already in place for some exporters. Furthermore, we find that the likelihood of convergence is greater between pairs of price series that are characterized as high quality or having the same country of origin or having similar market share. Evidence also suggests that a converged pairing is more likely to have a smaller price differential if both price series are for low‐quality rice.

Published: January 2023

BackgroundThe Purkinje fibers convey the electrical impulses at much higher speed than the working myocardial cells. Thus, the distribution of the Purkinje network is of paramount importance for the timing and coordination of ventricular activation. The Purkinje fibers are found in the subendocardium of all species of mammals, but some mammals also possess an intramural Purkinje fiber network that provides for relatively instantaneous, burst‐like activation of the entire ventricular wall, and gives rise to an rS configuration in lead II of the ECG.AimTo relate the topography of the horse heart and the distribution and histology of the conduction system to the pattern of ventricular activation as a mechanism for the unique electrical axis of the equine heart.MethodsThe morphology and distribution of the cardiac conduction system was determined by histochemistry. The electrical activity was measured using ECG in the Einthoven and orthogonal configuration.ResultsThe long axis of the equine heart is close to vertical. Outside the nodal regions the conduction system consisted of Purkinje fibers connected by connexin 43 and long, slender parallel running transitional cells. The Purkinje fiber network extended deep into the ventricular walls. ECGs recorded in an orthogonal configuration revealed a mean electrical axis pointing in a cranial‐to‐left direction indicating ventricular activation in an apex‐to‐base direction.ConclusionThe direction of the mean electrical axis in the equine heart is determined by the architecture of the intramural Purkinje network, rather than being a reflection of ventricular mass.
Notes on marriage markets with weak externalities
Authors: Fonseca‐Mairena María Haydée , Triossi Matteo 
Published: January 2023

AbstractWe consider marriage markets with externalities. We focus on weak externalities, that is, markets in which each agent is primarily concerned about her partner. We formalize and prove the claim that weak externalities are not so significant in the marriage market: in this case, the ω‐core and the α‐core coincide and are both nonempty. In addition, we show that, if we allow agents to block matchings without changing their mate, the results do not longer hold.

Published: January 2023

AbstractBackgroundWhen peribulbar infiltrates are absent, other histopathologic findings are necessary to distinguish alopecia areata (AA) from pattern hair loss (PHL). The purpose of this study is to determine which histopathologic features are most useful for differentiation.MethodsA retrospective slide review was conducted of AA and PHL scalp biopsy specimens from 2014 to 2019 at a tertiary referral center.ResultsNinety‐six cases were retrieved, of which 38 were AA. Peribulbar infiltrates were identified in 24 AA (63.2%) cases. A catagen/telogen shift was observed more frequently in AA than PHL (25 cases, 65.5% vs. 10 cases, 17.2%; p ≤ 0.0001). Lymphocytes (4 cases, 10.5% vs. 1 case, 1.7%; p = 0.058) and melanin (25 cases, 65.8% vs. 5 cases, 8.6%; p ≤ 0.0001) in fibrous tracts were more common in AA. Apoptotic bodies within vellus hairs were more frequently identified in AA (32 cases, 84.2% vs. 37 cases, 63.8%; p = 0.030). Small dystrophic follicles were also more common in AA (16 cases, 42.1% vs. 1 case, 1.7%; p < 0.0001).ConclusionsCommon features of AA other than peribulbar infiltrates include a catagen/telogen shift, melanin in fibrous tracts, and small dystrophic follicles. Practitioners should consider these features when distinguishing AA from PHL in specimens without peribulbar infiltrates. The retrospective design limits our ability to exclude multifactorial alopecia, such as telogen effluvium.

AbstractObjectiveTo compare the fetal pulmonary artery Doppler indices of pregnant women with autoimmune diseases such as systemic lupus erythematosus (SLE), Sjögren's syndrome (SS), and antiphospholipid syndrome (APS) with healthy pregnant women.MethodsThirty‐nine pregnancies were included in the case group, 19 of them SLE, 12 with SS, and eight with APS. The gestational age‐matched 54 healthy pregnant women were included in the control group. Peak systolic velocity, time‐averaged velocity, systolic/diastolic ratio, pulsatility index, resistance index, acceleration time (AT), ejection time (ET), and AT/ET ratio were obtained from pulmonary artery waveform by using spectral Doppler ultrasound.ResultsSignificantly shorter AT and lower AT/ET ratio were detected in the case group (p = < .001, p = < .001, respectively). The shortening of AT and decreasing of the AT/ET ratio were more predominant in the APS group. However, there was no significant difference between the SLE, SS, and APS groups in fetal pulmonary artery Doppler indices. Also, a moderate correlation was found between maternal disease duration (years) and fetal pulmonary artery AT (r = −.516, p = .001) and AT/ET ratio (r = −.558, p = < .001).ConclusionFetal pulmonary artery Doppler indices may be affected in maternal autoimmune diseases. Further studies are needed to evaluate fetal pulmonary Doppler indices such as AT and AT/ET ratio to predict neonatal respiratory morbidity and lung maturation in pregnant women with SLE, SS, and APS.

Published: January 2023

AbstractRadiation recall reactions are inflammatory reactions confined to previously irradiated tissues, often of drug‐induced etiology, particularly with anticancer therapies. Other drugs, in particular COVID‐19 vaccines, may also be involved. To describe radiation recall reactions under non‐anticancer drugs more precisely, we extracted the cases of radiation recall reactions associated with non‐anticancer drugs from WHO pharmacovigilance database VigiBase®. We performed two analyses from this extraction: a global analysis and an analysis focusing on vaccination‐related issues. We extracted 120 cases corresponding to 269 drugs, of which 130 were non‐anticancer (22 vaccines). Among the non‐anticancer drugs, tozinameran was the most reported treatment (4.46% of cases), followed by levofloxacin (2.97%) and folinic acid (2.60%), dexamethasone (2.23), and ChAdOx1 nCoV‐19 vaccine and prednisone (1.86% each). Among vaccines, tozinameran (54.55% of cases) was the most reported, followed by ChAdOx1 nCoV‐19 (22.73%), HPV and inactivated influenza vaccine (9.09% each), and elasomeran (4.55%). Our study first describes the occurrence of radiation recall reactions during non‐anticancer treatment. It also highlights a potential safety signal with COVID‐19 vaccines.

Published: January 2023

AbstractThe contribution of agriculture to the sustainable development goals requires climate‐smart and profitable farm innovations. Increasing the ammonia fertilizer applications to meet the global food demands results in high agricultural costs, environmental quality deterioration, and global warming, without a significant increase in crop yield. Here, we reported that a third microbial ammonia oxidation process, complete ammonia oxidation (comammox), is contributing to a significant ammonia fertilizer loss (41.9 ± 4.8%) at the rate of 3.53 ± 0.55 mg N kg−1 day−1 in agricultural soils around the world. The contribution of comammox to ammonia fertilizer loss, occurring mainly in surface agricultural soil profiles (0–0.2 m), was equivalent to that of bacterial ammonia oxidation (48.6 ± 4.5%); both processes were significantly more important than archaeal ammonia oxidation (9.5 ± 3.6%). In contrast, comammox produced less N2O (0.98 ± 0.44 μg N kg−1 day−1, 11.7 ± 3.1%), comparable to that produced by archaeal ammonia oxidation (16.4 ± 4.4%) but significantly lower than that of bacterial ammonia oxidation (72.0 ± 5.1%). The efficiency of ammonia conversion to N2O by comammox (0.02 ± 0.01%) was evidently lower than that of bacterial (0.24 ± 0.06%) and archaeal (0.16 ± 0.04%) ammonia oxidation. The comammox rate increased with increasing soil pH values, which is the only physicochemical characteristic that significantly influenced both comammox bacterial abundance and rates. Ammonia fertilizer loss, dominated by comammox and bacterial ammonia oxidation, was more intense in soils with pH >6.5 than in soils with pH <6.5. Our results revealed that comammox plays a vital role in ammonia fertilizer loss and sustainable development in agroecosystems that have been previously overlooked for a long term.
