AbstractThis paper proposed a new weight function modified critical distance method to predict the creep life of Ni‐based single‐crystal superalloy plate with film‐cooling holes through experimental and numerical research. The creep test and numerical simulation results both indicated that cracks originated around the hole, and the location of the maximum Mises stress point around the hole was consistent with the crack initiation point shown in the test results. Considering the stress gradient in the thickness direction, a critical fracture surface was defined, and the stress distribution at the critical fracture surface was defined using polynomials. An improved stress gradient function and weight function were introduced to calculate the effective stress at the critical fracture surface. The effective stress was used to predict the creep life of the plate with film‐cooling holes. Compared with the experimental results, the errors were all within the dispersion band of 1.5 times, indicating good prediction results.

AbstractAimThis study aimed to investigate the upstream regulators and specific mechanisms of metastasis‐associated lung adenocarcinoma transcript 1 (MALAT1) in the odontoblastic differentiation of human dental pulp stem cells (hDPSCs).MethodologyHuman dental pulp stem cells were isolated and cultured, followed by conducting loss‐ or gain‐of‐function experiments on ATF4 and loss experiments on MALAT1 to elucidate their respective biological functions in odontoblastic differentiation. Chromatin immunoprecipitation assays and RNA immunoprecipitation were performed to uncover the interaction between ATF4‐MALAT1 and MALAT1‐JMJD3, respectively. The odontoblastic differentiation was estimated by the mRNA and protein of DSPP and DMP1, as well as alkaline phosphatase staining.ResultsExpression of MALAT1 was upregulated in the hDPSCs cultured in an odontoblastic medium, and MALAT1 downregulation suppressed the odontoblastic differentiation of the hDPSCs. Subsequent experiments confirmed that ATF4 promoted odontoblastic differentiation and induced MALAT1 expression by binding to the MALAT1 promoter region. Further experiments revealed that nuclear MALAT1 interacted with JMJD3. MALAT1 knockdown decreased the JMJD3 protein level and demethylase activity, and it enhanced H3K27me3 occupancy of the promoter region of DSPP and DMP1, resulting in the inhibition of DSPP and DMP1 transcription. Importantly, JMJD3 overexpression significantly attenuated the inhibition of odontoblastic differentiation induced by MALAT1 knockdown.ConclusionsATF4‐regulated MALAT1 plays a positive regulatory role in odontoblastic differentiation of hDPSCs through JMJD3‐mediated H3K27me3 modifications of the DSPP and DMP1 promoters.
COLLEGE EXPANSION, TRADE, AND INNOVATION: EVIDENCE FROM CHINA
Authors: Ma Xiao 
Published: October 2023

AbstractChina has expanded the yearly quota on newly admitted college students by more than seven times since 1999. How did this massive education expansion affect firms' export and innovation choices? I document that after this expansion impacted the labor market, manufacturing firms' innovation increased considerably, especially among exporting firms, accompanied by sizable skill upgrading of exports. I then develop a multi‐industry spatial equilibrium model, featuring skill intensity differences across industries and heterogeneous firms' innovation and export choices. Quantitatively, the college expansion explained 72% of increases in China's manufacturing research and development (R&D) intensity between 2003 and 2018 and also triggered export skill upgrading.
AN EQUILIBRIUM LABOR MARKET MODEL WITH INTERNAL AND EXTERNAL REFERRALS
Authors: Lang Youze , Yang Youzhi 
Published: October 2023

AbstractAbout 40% of workers find their jobs through referrals. We distinguish between two types of referrals based on whether the referrer works at the hiring firm (internal referrals) or not (external referrals). Interestingly, jobs found through internal (external) referrals pay more (less) than those found through formal methods. An equilibrium labor market model is then built by introducing an incentive‐compatible mechanism through which workers can share job opening information. A nondegenerate wage distribution arises in equilibrium with a wage premium (penalty) for internal (external) referrals. When calibrated, our model can capture these salient features of the U.S. labor market.
Competition in the online platform: impacts of blockchain technology adoption

Published: October 2023

AbstractConsumers typically have a higher preference and trust for traceability products, which makes many online platforms (e.g., JD.com, Tmall Global) and food manufacturers (e.g., BeingMate, Mengniu, Moutai) use blockchain‐enabled traceability to improve product transparency and trust. This paper systematically analyzes the effects of constructing blockchain‐based information traceability systems (BITS) on supply chains led by different members in a dual‐channel supply chain consisting of a manufacturer and an online platform. We studied the optimal operational strategy for dual‐channel members in two scenarios without blockchain technology and different members (i.e., manufacturer and online platform) as leaders in building BITS. We find that BITS adoption can effectively improve the performance of supply chain members, but the value added to blockchain depends on the level of consumer goodwill toward BITS, the level of competition, and the proportion of cost sharing. We show that either the manufacturer or the online platform can be more profitable as a leader in building BITS. Further, we showed that either the manufacturer or the online platform, as the leader of BITS construction, should bear more construction costs so that the nonleader builder can gain more profit to achieve a win‐win result. Interestingly, as the leader of BITS construction bearing more construction costs can achieve higher system total profit.

AbstractUnder semi‐natural conditions, behavioural schedules differ in juvenile and adult Bar‐headed geese and in pairs with and without goslings. Goslings also interfere in the pair's synchronisation of behavioural actions. Three families and two pairs (10 adults and 18 juveniles) were observed. The observations were performed once or twice a month on 2–5 successive days. On these days a family's activities were recorded once every 20 min between sunrise and sunset. The results are discussed with respect to findings in wild‐living Bar‐headed geese and other goose species.
Suicide Survivors: Psychotherapeutic Implications of Egocide*
Authors: Rosen David H. 
Published: October 2023

ABSTRACT: Interviews with seven of ten known survivors of jumps from the Golden Gate Bridge and San Francisco‐Oakland Bay Bridge revealed that all of them experienced transcendence and spiritual rebirth phenomena. The psychotherapeutic implications of these findings lie in helping depressed and suicidal individuals confront death in a symbolic and meaningful way. The issue is one of “egocide” (symbolic suicide) and aiding individuals in the rebirth process. In this way actual suicides cen be prevented. When individuals experience partial “deaths” (like loss, failure, rejection, depression, suicidal states, or negative parts of their egos), there is opportunity for “rebirth” (positive transformation, creative change, growth, and significant spiritual reawakening). The therapeutic task is to help individuals differentiate between “ego death” and total death and to discover through the creative process of psychotherapy that overt suicide need not be a solution.
O Compassionate Ones, you who possess the wisdom of understanding, the love of compassion, the power of doing divine deeds and of protecting in comprehensible measure: This person is passing from this world to the next. He is taking a great leap. The light of this world has faded for him. He has entered solitude with his Karmic forces. He has gone into a vast silence. He is borne away by the Great Ocean (of birth and death).—–The Prayer (Adapted from The Tibetan Book of the Dead, W. Y. Evans‐Wentz, Ed., 1965.)
The advocacy process in Canadian community health nursing: A collaborative ethnography
Authors: Mccready Geneviève , Laperrière Hélène 
Published: October 2023

AbstractAimsTo shed light on the process of advocacy in the context of community health nursing, through a methodology inspired by the epistemologies of the South.DesignWe conducted a collaborative ethnography in a community health centre in Canada.Methodsde Sousa Santos' epistemologies of the South, a typology of advocacy and main themes from historic research informed the methodology. Data were collected between 2016 and 2018 through 420 h of fieldwork observations and three group discussions, including a collective process to co‐construct interpretations with participants. Twenty‐one nurses participated in the study.ResultsNurses had sufficient work flexibility to practice advocacy actions focused on individuals and groups. They also engaged in attempts at policy reform in the form of defending access to appropriate care and changing the mode of care organization. However, these were curbed by bureaucracy and administrative rules, resulting in the eventual dismissal of health promotion actions and experiences of moral distress.ConclusionDespite the political climate of their work environment impeding social justice agendas, nurses' advocacy practices showed a persistence of moral values and ideals in coherence with the regional nursing legacy.Implications for the Profession and/or Patient CareActing at the organizational level and involving field nurses in decision making are potential avenues for increasing policy advocacy efficacy.ImpactExamining contexts through another epistemic lens and methods of research drawing on history and anthropology has shed light on a process of advocacy. This research shows that organizations need to equip themselves with mechanisms to promote the sharing of realities between nurses, thereby building collective advocacy.Reporting MethodThe research adheres to the EQUATOR guidelines with SRQR and COREQ methods.Patient or Public ContributionNo patient or public contribution.
Estimating multiple years, tributary‐specific, and overall Atlantic salmon smolt abundance in a large Canadian catchment using capture–mark–recapture experiments
Authors: Dauphin Guillaume J. R. , Gillis Carole‐Anne , Chaput Gérald J. 
Published: October 2023

AbstractPopulation monitoring of Atlantic salmon (Salmo salar L.) abundance is an essential element to understand annual stock variability and inform fisheries management processes. Smolts are the life stage marking the transition from the freshwater to the marine phase of anadromous Atlantic salmon. Estimating smolt abundance allows for subsequent inferences on freshwater and marine survival rates. Annual abundances of out‐migrating Atlantic salmon smolts were estimated using Bayesian models and an 18‐year capture–mark–recapture time series from two to five trapping locations within the Restigouche River (Canada) catchment. Some of the trapping locations were at the outlet of large upstream tributaries, and these sampled a portion of the total out‐migrating population of smolts for the watershed, whereas others were located just above the head of tide of the Restigouche River and sampled the entire run of salmon smolts. Due to logistic and environmental conditions, not all trapping locations were operational each year. Additionally, recapture rates were relatively low (<5%), and the absolute number of recaptures was relatively few (most often a few dozen), leading to incoherent and highly uncertain estimates of tributary‐specific and whole catchment abundance estimates when the data were modeled independently among trapping locations and years. Several models of increasing complexity were tested using simulated data, and the best‐performing model in terms of bias and precision incorporated a hierarchical structure among years on the catchability parameters and included an explicit spatial structure to account for the annual variations in the number of sampled locations within the watershed. When the best model was applied to the Restigouche River catchment dataset, the annual smolt abundance estimates varied from 250,000 to 1 million smolts, and the subbasin estimates of abundance were consistent with the spatial structure of the monitoring programme. Ultimately, increasing the probabilities of capture and the absolute number of recaptures at the different traps will be required to improve the precision and reduce the bias of the estimates of smolt abundance for the entire basin and within subbasins of the watershed. The model and approach provide a significant improvement in the models used to date based on independent estimates of abundance by trapping location and year. Total abundance and relative production in discrete spawning, nesting, or rearing areas provide critical information to appropriately understand and manage the threats to species that can occur at subpopulation spatial scales.
What acoustic telemetry can and cannot tell us about fish biology
Authors: Jacoby David M. P. , Piper Adam T. 
Published: October 2023

AbstractAcoustic telemetry (AT) has become ubiquitous in aquatic monitoring and fish biology, conservation, and management. Since the early use of active ultrasonic tracking that required researchers to follow at a distance their species of interest, the field has diversified considerably, with exciting advances in both hydrophone and transmitter technology. Once a highly specialized methodology, however, AT is fast becoming a generalist tool for those wishing to study or conserve fishes, leading to diversifying application by non‐specialists. With this transition in mind, we evaluate exactly what AT has become useful for, discussing how the technological and analytical advances around AT can address important questions within fish biology. In doing so, we highlight the key ecological and applied research areas where AT continues to reveal crucial new insights and, in particular, when combined with complimentary research approaches. We provide a comprehensive breakdown of the state of the art for applications of AT, discussing the ongoing challenges, where its strengths lie, and how future developments may revolutionize fisheries management, behavioral ecology and species protection. Through selected papers we illustrate specific applications across the broad spectrum of fish biology. By bringing together the recent and future developments in this field under categories designed to broadly capture many aspects of fish biology, we hope to offer a useful guide for the non‐specialist practitioner as they attempt to navigate the dizzying array of considerations and ongoing developments within this diverse toolkit.

Published: October 2023

AbstractThis study focuses on the relationship between local compression and local bruise volume of kiwifruits by means of finite element method (FEM). The effects of four indenter shapes and three compression directions on the local kiwifruit bruise were considered. The local bruise volume and the irregular cross section area of kiwifruit were calculated. Multi‐scale kiwifruit 3D modelling based on irregular cross‐sectional area computed by slice‐integration method. Local compression bruise was simulated by FEM. The results of the local bruise test show that the contact force and the bruise volume of kiwifruit are positive linear correlation. Comparing the simulation with the experimental, the mean absolute percentage error (MAPE) of the reconstructed model is 0.0394, and the R2 of contact force–bruise volume curve is 0.8203. The maximum equivalent forces and abrasions occur in the 0° and 90° loading directions with the square indenter has been showed by FEM results.Practical applicationsSe‐enriched kiwifruit has high nutrition and economic value. Kiwifruits are often influenced by a variety of factors and processes from harvest to consumption time. Cleaning, transport, and various processing operations including peeling and slicing in the kiwifruit industry are responsible for local bruise to kiwifruit. Therefore, understanding the mechanism of local bruise caused by local contact force of kiwifruit plays an important role in reducing kiwifruit waste in the postharvest stage. Local bruise mechanisms can be used in harvesting and post‐harvest mechanical design and product transportation and positioning equipment.
Heterozygous NF1 dermal fibroblasts modulate exosomal content to promote angiogenesis in a tissue‐engineered skin model of neurofibromatosis type‐1

Published: October 2023

AbstractNeovascularization is a critical process in tumor progression and malignant transformation associated with neurofibromatosis type 1 (NF1). Indeed, fibroblasts are known to play a key role in the tumoral microenvironment modification by producing an abundant collagenous matrix, but their contribution in paracrine communication pathways is poorly understood. Here, we hypothesized that NF1 heterozygosis in human dermal fibroblasts could promote angiogenesis through exosomes secretion. The purposes of this study are to identify the NF1 fibroblast‐derived exosome protein contents and to determine their proangiogenic activity. Angiogenic proteome measurement confirmed the overexpression of VEGF and other proteins involved in vascularization. Tube formation of microvascular endothelial cells was also enhanced in presence of exosomes derived from NF1 skin fibroblasts. NF1 tissue‐engineered skin (NF1‐TES) generation showed a significantly denser microvessels networks compared to healthy controls. The reduction of exosomes production with an inhibitor treatment demonstrated a drastic decrease in blood vessel formation within the dermis. Our results suggest that NF1 haploinsufficiency alters the dermal fibroblast function and creates a pro‐angiogenic signal via exosomes, which increases the capillary formation. This study highlights the potential of targeting exosome secretion and angiogenesis for therapeutic interventions in NF1.image

AbstractCarnivorans are well‐known for their exceptional backbone mobility, which enables them to excel in fast running and long jumping, leading to them being among the most successful predators amongst terrestrial mammals. This study presents the first large‐scale analysis of mobility throughout the presacral region of the vertebral column in carnivorans. The study covers representatives of 6 families, 24 genera and 34 species. We utilized a previously developed osteometry‐based method to calculate available range of motion, quantifying all three directions of intervertebral mobility: sagittal bending (SB), lateral bending (LB), and axial rotation (AR). We observed a strong phylogenetic signal in the structural basis of the vertebral column (vertebral and joint formulae, length proportions of the backbone modules) and an insignificant phylogenetic signal in most characteristics of intervertebral mobility. This indicates that within the existing structure (stabilization of which occurred rather early in different phylogenetic lineages), intervertebral mobility in carnivorans is quite flexible. Our findings reveal that hyenas and canids, which use their jaws to seize prey, are characterized by a noticeably elongated cervical region and significantly higher SB and LB mobility of the cervical joints compared to other carnivorans. In representatives of other carnivoran families, the cervical region is very short, but the flexibility of the neck (both SB and LB) is significantly higher than that of short‐necked odd‐toed and even‐toed ungulates. The lumbar region of the backbone in carnivorans is dorsomobile in the sagittal plane, being on average ~23° more mobile than in artiodactyls and ~38° more mobile than in perissodactyls. However, despite the general dorsomobility, only some representatives of Canidae, Felidae, and Viverridae are superior in lumbar flexibility to the most dorsomobile ungulates. The most dorsomobile artiodactyls are equal or even superior to carnivorans in their ability to engage in dorsal extension during galloping. In contrast, carnivorans are far superior to ungulates in their ability to engage ventral flexion. The cumulative SB in the lumbar region in carnivorans largely depends on the mode of running and hunting. Thus, adaptation to prolonged and enduring pursuit of prey in hyenas is accompanied by markedly reduced SB flexibility in the lumbar region. A more dorsostable run is also a characteristic of the Ursidae, and the peculiar maned wolf. Representatives of Felidae and Canidae have significantly more available SB mobility in the lumbar region. However, they fully engage it only occasionally at key moments of the hunt associated with the direct capture of the prey or when running in a straight line at maximum speed.
