Effects of soldering temperature and preheating temperature on the properties of Sn–Zn solder alloys using wave soldering
Authors: Qu Songtao , Shi Qingyu , Zhang Gong , Dong Xinhua , Xu Xiaohua 
Published: July 2024

Purpose
This study aims to address the problem of low-temperature wave soldering in industry production with Sn-9Zn-2.5 Bi-1.5In alloys and develop qualified process parameters. Sn–Zn eutectic alloys are lead-free solders applied in consumer electronics due to their low melting point, high strength, and low cost. In the electronic assembly industry, Sn–Zn eutectic alloys have great potential for use.

Design/methodology/approach
This paper explored developing and implementing process parameters for low-temperature wave soldering of Sn–Zn alloys (SN-9ZN-2.5BI-1.5 In). A two-factor, three-level design of the experiments experiment was designed to simulate various conditions parameters encountered in Sn–Zn soldering, developed the nitrogen protection device of waving soldering and proposed the optimal process parameters to realize mass production of low-temperature wave soldering on Sn–Zn alloys.

Findings
The Sn-9Zn-2.5 Bi-1.5In alloy can overcome the Zn oxidation problem, achieve low-temperature wave soldering and meet IPC standards, but requires the development of nitrogen protection devices and the optimization of a series of process parameters. The design experiment reveals that preheating temperature, soldering temperature and flux affect failure phenomena. Finally, combined with the process test results, an effective method to support mass production.

Research limitations/implications
In term of overcome Zn’s oxidation characteristics, anti-oxidation wave welding device needs to be studied. Various process parameters need to be developed to achieve a welding process with lower temperature than that of lead solder(Sn–Pb) and lead-free SAC(Sn-0.3Ag-0.7Cu). The process window of Sn–Zn series alloy (Sn-9Zn-2.5 Bi-1.5In alloy) is narrow. A more stringent quality control chart is required to make mass production.

Practical implications
In this research, the soldering temperature of Sn-9Zn-2.5 Bi-1.5In is 5 °C and 25 °C lower than Sn–Pb and Sn-0.3Ag-0.7Cu(SAC0307). To the best of the authors’ knowledge, this work was the first time to apply Sn–Zn solder alloy under actual production conditions on wave soldering, which was of great significance for the study of wave soldering of the same kind of solder alloy.

Social implications
Low-temperature wave soldering can supported green manufacturing widely, offering a new path to achieve carbon emissions for many factories and also combat to international climate change.

Originality/value
There are many research papers on Sn–Zn alloys, but methods of achieving low-temperature wave soldering to meet IPC standards are infrequent. Especially the process control method that can be mass-produced is more challenging. In addition, the metal storage is very high and the cost is relatively low, which is of great help to provide enterprise competitiveness and can also support the development of green manufacturing, which has a good role in promoting the broader development of the Sn–Zn series.

Abstract

The functioning of a tree is shaped by the neighbouring species through the interspecific interaction and local environments. The functional trait composition of the neighbourhood could provide mechanistic insights into the effects of neighbours on the resource strategies of focal trees.

In this study, we deployed an automated high‐frequency measurement of the sap flow density (SFD) and the radial growth of 48 trees of 12 species at BEF‐China, a large‐scale forest biodiversity manipulation experiment, to investigate the consequences and underlying mechanisms of the functional trait composition of the neighbourhood on the sap flow and radial growth of focal trees.

We found a positive relationship between SFD and growth, reflecting the important supportive role of sap flow in tree growth. High functional diversity (FD) of the neighbourhood depressed SFD but promoted growth when considering all species, and thus promoted water‐use efficiency. Acquisitiveness of neighbouring trees positively affected growth, suggesting interspecific facilitation. Furthermore, neighbourhood FD benefits evergreen focal trees by promoting growth. However, in deciduous focal trees, neighbourhood FD reduced SFD but had no significant effects on growth.

Our findings suggest that considering the functional trait composition of neighbourhood communities will support effective afforestation and forest management.

AbstractBreeding is a key component of the life history of birds. Documenting diverse aspects of their breeding biology provides valuable natural history data that can be used to address questions of evolutionary, ecological, or conservation significance. Despite its importance, this information is scarce for most Neotropical species. We compiled 1180 breeding records corresponding to 325 bird species for the period 2000–2021, through an in‐depth review of photo or video records from Peru, sourced from Macaulay Library and iNaturalist platforms. We determined the geographical distribution of the breeding records, described patterns of activity and nesting behavior (i.e., host plant preference and clutch size), and explored the timing of breeding. Our study represents one of the few efforts to provide nationwide data on breeding birds in the Neotropical region. We also offer broad taxonomic coverage for further studies interested in testing hypotheses on the variation of reproductive traits and timing at both local and regional scales.

Published: July 2024

AbstractThis article introduces the productivity heterogeneity of Melitz, M. J. (2003). Econometrica, 71(6), 1695–1725 into the footloose entrepreneur model of Forslid, R., and Ottaviano, G. I. (2003). Journal of Economic Geography, 3(3), 229–240 to explore the industrial spatial distribution between two regions. We suggest a negative relationship between the shape parameter of the Pareto distribution and the share of skilled workers in a region. It enhances the escape competition effect to avoid agglomeration when the share of skilled workers in a region increases to generate intensified competition. This effect allows the equal distribution outcome to be sustained for a larger range of transport costs.

Published: July 2024

AbstractPorcine epidemic diarrhoea virus (PEDV) infects pigs of all ages by invading small intestine, causing acute diarrhoea, vomiting, and dehydration with high morbidity and mortality among newborn piglets. However, current PEDV vaccines are not effective to protect the pigs from field epidemic strains because of poor mucosal immune response and strain variation. Therefore, it is indispensable to develop a novel oral vaccine based on epidemic strains. Bacillus subtilis spores are attractive delivery vehicles for oral vaccination on account of the safety, high stability, and low cost. In this study, a chimeric gene CotC‐Linker‐COE (CLE), comprising of the B. subtilis spore coat gene cotC fused to the core neutralizing epitope CO‐26 K equivalent (COE) of the epidemic strain PEDV‐AJ1102 spike protein gene, was constructed. Then recombinant B. subtilis displaying the CLE on the spore surface was developed by homologous recombination. Mice were immunized by oral route with B. subtilis 168‐CLE, B. subtilis 168, or phosphate‐buffered saline (PBS) as control. Results showed that the IgG antibodies and cytokine (IL‐4, IFN‐γ) levels in the B. subtilis 168‐CLE group were significantly higher than the control groups. This study demonstrates that B. subtilis 168‐CLE can generate specific systemic immune and mucosal immune responses and is a potential vaccine candidate against PEDV infection.
PRPS2‐mediated modulation of the antitumor immune response in lung cancer through CCL2‐mediated tumor‐associated macrophages and myeloid‐derived suppressor cells
Authors: Liu Qing , Wu Ningzi , Hou Peifeng 
Published: July 2024

AbstractBackgroundPhosphoribosyl pyrophosphate synthetase 2 (PRPS2) is known as an oncogene in many types of cancers, including lung cancer. However, its role in regulating tumor‐associated macrophages (TAM) and myeloid‐derived suppressor cells (MDSC) remains unclear. Our study aimed to explore the involvement of PRPS2 in TAM and MDSC regulation.MethodsStable Lewis lung cancer (LLC) cell lines were established using a lentivirus system. These LLC lines were then used to establish tumor model in mice. The levels of target genes were determined using qPCR, western blotting, and ELISA assays. The percentage of different immune cell types was analyzed using fluorescence‐activated cell sorting. The chemotaxis ability of TAM and MDSC was evaluated using an in vitro transwell chemotaxis assay.ResultsNotably, PRPS2 was found to regulate the chemotaxis of TAM and MDSC in tumor cells, as evidenced by the positive correlation of PRPS2 expression levels and abundance of TAM and MDSC populations. In addition, the expression of CCL2, mediated by PRPS2, was identified as a key factor in the chemotaxis of TAM and MDSC, as evidenced by a significant reduction in macrophages and MDSC numbers in the presence of the CCL2 antibody. Furthermore, in vivo experiments confirmed the involvement of PRPS2 in mediating CCL2 expression. PRPS2 was also found to regulate immune cell infiltration into tumors, whereas knockdown of CCL2 reversed the phenotype induced by PRPS2 overexpression. In tumor tissues from mice implanted with LLC‐PRPS2‐shCCL2 cells, a notable increase in CD4+ and CD8+ T cell percentages, alongside a marked decrease in TAMs, M‐MDSC, and PMN‐MDSC, was observed.ConclusionTaken together, PRPS2 plays a crucial role in modulating the antitumor immune response by reprogramming CCL2‐mediated TAM and MDSC.

AbstractThe dynamicity of the mitochondrial network is crucial for meeting the ever‐changing metabolic and energy needs of the cell. Mitochondrial fission promotes the degradation and distribution of mitochondria, while mitochondrial fusion maintains mitochondrial function through the complementation of mitochondrial components. Previously, we have reported that mitochondrial networks are tubular, interconnected, and well‐organized in young, healthy C. elegans, but become fragmented and disorganized with advancing age and in models of age‐associated neurodegenerative disease. In this work, we examine the effects of increasing mitochondrial fission or mitochondrial fusion capacity by ubiquitously overexpressing the mitochondrial fission gene drp‐1 or the mitochondrial fusion genes fzo‐1 and eat‐3, individually or in combination. We then measured mitochondrial function, mitochondrial network morphology, physiologic rates, stress resistance, and lifespan. Surprisingly, we found that overexpression of either mitochondrial fission or fusion machinery both resulted in an increase in mitochondrial fragmentation. Similarly, both mitochondrial fission and mitochondrial fusion overexpression strains have extended lifespans and increased stress resistance, which in the case of the mitochondrial fusion overexpression strains appears to be at least partially due to the upregulation of multiple pathways of cellular resilience in these strains. Overall, our work demonstrates that increasing the expression of mitochondrial fission or fusion genes extends lifespan and improves biological resilience without promoting the maintenance of a youthful mitochondrial network morphology. This work highlights the importance of the mitochondria for both resilience and longevity.

AbstractBackgroundExcessive alcohol consumption has a multifaceted impact on the body's metabolic pathways and organ systems. The objectives of this study were to characterize global metabolomic changes and identify specific pathways that are altered in individuals with excessive alcohol use.MethodsThis exploratory study included 22 healthy controls with no known history of excessive alcohol use and 38 patients identified as using alcohol excessively. A Fibrosis‐4 score was used to determine the risk of underlying alcohol‐associated liver disease among the excessive drinkers.ResultsWe found significantly altered urinary and serum metabolites among excessive drinkers, affecting various metabolic pathways including the metabolism of lipids, amino acids and peptides, cofactors and vitamins, carbohydrates, and nucleotides. Levels of two steroid hormones—5alpha‐androstan‐3beta,17beta‐diol disulfate and androstenediol (3beta,17beta) disulfate—were significantly higher in both the serum and urine samples of excessive drinkers. These elevated levels may be associated with a higher risk of liver fibrosis in individuals with excessive alcohol use.ConclusionAlcohol consumption leads to marked alterations in multiple metabolic pathways, highlighting the systemic impact of alcohol on various tissues and organ systems. These findings provide a foundation for future mechanistic studies aimed at elucidating alcohol‐induced changes in these metabolic pathways and their implications.
The rise of and demand for identity‐oriented media coverage
Authors: Hopkins Daniel J. , Lelkes Yphtach , Wolken Samuel 
Published: July 2024

AbstractWhile some assert that social identities have become more salient in American media coverage, existing evidence is largely anecdotal. An increased emphasis on social identities has important political implications, including for polarization and representation. We first document the rising salience of different social identities using natural language processing tools to analyze all tweets from 19 media outlets (2008–2021) alongside 553,078 URLs shared on Facebook. We then examine one potential mechanism: Outlets may highlight meaningful social identities—race/ethnicity, gender, religion, or partisanship—to attract readers through various social and psychological pathways. We find that identity cues are associated with increases in some forms of engagement on social media. To probe causality, we analyze 3,828 randomized headline experiments conducted via Upworthy. Headlines mentioning racial/ethnic identities generated more engagement than headlines that did not, with suggestive evidence for other identities. Identity‐oriented media coverage is growing and rooted partly in audience demand.
A quasi‐experimental investigation of differences between face‐to‐face and videoconference interviews in an actual selection process

Published: July 2024

AbstractVideoconference interviews are now integral to many selection processes. Theoretical arguments and empirical findings suggest that videoconference interviews may lead to different interview performance ratings in comparison to Face‐to‐Face (FTF) interviews. This has led to the question of the comparability of the psychometric properties of videoconferences and FTF interviews. However, evidence from actual selection processes stems from the beginning of the century, and recent findings predominantly stem from simulated interview contexts. We present insights from an actual selection process within a large European organization where we had the unique opportunity for a quasi‐experimental investigation of differences between videoconference and FTF interviews. Initially, the organization conducted FTF interviews, and after the onset of the COVID‐19 pandemic, the interviews were conducted via videoconference. We examine mean differences in applicant performance ratings and evidence for response format‐related validity differences. There were only small, non‐significant mean differences and no evidence for response format related validity differences. We discuss possible causes for discrepancies in our findings compared to previous research. Furthermore, we conclude that downstream consequences of differences between FTF and videoconference interviews may be lower than previously expected. We end with a call for research on the interaction between technology‐design and selection‐tool‐design features.

Published: July 2024

AbstractSerum laminin‐γ2 monomer (Lm‐γ2m) is a potent predictive biomarker for hepatocellular carcinoma (HCC) onset in patients with hepatitis C infection who achieve a sustained virologic response with liver cirrhosis (LC) and for the onset of extrahepatic metastases in early‐stage HCC. Although Lm‐γ2m involvement in late‐stage cancer progression has been well investigated, its precise roles in HCC onset remain to be systematically investigated. Therefore, we analyzed an HCC model, human hepatocytes and cholangiocytes, and surgically resected liver tissues from patients with HCC to understand the roles of Lm‐γ2m in HCC onset. Ck‐19‐ and EpCAM‐positive hepatic progenitor cells (HPCs) in the liver of pdgf‐c transgenic HCC mouse model with ductular reaction showed ectopic expression of Lm‐γ2m. Forced expression of Lm‐γ2m in hepatocytes adjacent to HPCs resulted in enhanced tumorigenicity, cell proliferation, and migration in immortalized hepatocytes, but not in cholangiocytes in vitro. Further, pharmacological inhibition of epidermal growth factor receptor (EGFR) and c‐Jun activator JNK suppressed Lm‐γ2m‐induced hepatocyte transformation, suggesting the involvement of EGFR/c‐Jun signaling in the transformation, leading to HCC development. Finally, immunohistochemical staining of HCC tissues revealed a high level of Lm‐γ2 expression in the HPCs of the liver with ductular reaction in normal liver adjacent to HCC tissues. Overall, HPC‐derived Lm‐γ2m in normal liver with ductular reaction acts as a paracrine growth factor on surrounding hepatocytes and promotes their cellular transformation through the EGFR/c‐Jun signaling pathway. Furthermore, this is the first report on Lm‐γ2m expression detected in the normal liver with ductular reaction, a human precancerous lesion of HCC.
Long‐term retention and survival of cemented implant‐supported zirconia and metal‐ceramic single crowns: A retrospective study
Authors: Rammelsberg P. , Klotz A. L. 
Published: July 2024

AbstractObjectivesTo evaluate the effect of different cement types on the incidence of failure and loss of retention of zirconia and metal‐ceramic single crowns (SCs) cemented on implant abutments.MethodsWe placed 567 implant‐supported SCs in 358 patients and retrospectively evaluated long‐term retention for up to 12.8 years. The frameworks were made from metal alloy (n = 307) or zirconia (n = 260). SCs were cemented with permanent (glass‐ionomer cement; n = 376) or semipermanent cement (zinc oxide non‐eugenol cement; n = 191) on standardized (n = 446) or customized (n = 121) abutments. Kaplan–Meier curves were used to calculate the incidence of decementation. Differences between survival curves were assessed with log‐rank tests. Cox‐regression analysis was performed to evaluate multiple risk factors.ResultsOf the 567 SCs, 22 failed because of technical complications and four because of implant loss. Loss of retention was observed in 50 SCs. Analysis revealed a 7% probability of loss of retention for zirconia and 16% for metal‐ceramic SCs after 10 years (p = .011). After 5 years, loss of retention was higher for standardized abutments than for customized abutments (p = .014). The probability of loss of retention was higher with semipermanent than with permanent cement (p = .001). Cox‐regression analysis revealed semipermanent cement as the only significant risk factor for SC failure (p = .026).ConclusionsIn contrast to semipermanent cement, permanent cement provides acceptable long‐term retention of cemented implant‐supported SCs. These possible positive effects of customized abutments have to be controlled with larger sample sizes.
