Purpose
A novel grafted temperature-responsive ReO4− Imprinted composite membranes (Re-ICMs) was successfully prepared by using polyvinylidene fluoride (PVDF) resin membranes as substrates, this study aimed to separate and purify ReO effectively.

Design/methodology/approach
Re-ICMs were synthesized by PVDF resin membranes as the substrate, acrylic acid (AA), acrylamide (AM), ethylene glycol dimethacrylate (EGDMA) were functional monomers. The morphology and structure of Re-ICMs were characterized by scanning electron microscope and Fourier transform infrared spectroscopy.

Findings
The maximum adsorption capacity toward ReO4− was 0.1,163 mmol/g and the separation decree had relation to MnO4− was 19.3. The optimal operation conditions were studied detailedly and the results as follows: the molar ratios of AA, AM, EGDMA, ascorbic acid, NH4ReO4, were 0.8, 0.96, 0.02, 0.003 and 0.006. The optimal time and temperature were 20 h and 40°C, respectively. The Langmuir and pseudo-second-order models were fit these adsorption characteristics well.

Practical implications
Rhenium (Re) is mainly used to chemical petroleum and make superalloys for jet engine parts. This study was representing a technology in separate and purify of Re, which provided a method for the development of the petroleum and aviation industry.

Originality/value
This contribution provided a novel method to separate ReO4− from MnO4−. The maximum adsorption capacity was 0.1163 mmol/g at 35°C and the adsorption equilibrium time was within 2 h. Meanwhile, the adsorption selectivity rate ReO4−/MnO4− was 19.3 and the desorption rate was 78.3%. Controlling the adsorption experiment at 35°C and desorption experiment at 25°C in aqueous solution, it could remain 61.3% of the initial adsorption capacity with the adsorption selectivity rate of 13.3 by 10 adsorption/desorption cycles, a slight decrease, varied from 78.3% to 65.3%, in desorption rate was observed.

Published: December 2021

Purpose
The main purpose of this work is to explore the erosion wear characteristics of additively manufactured aluminium alloy. Additive manufacturing (AM), also known as three-dimensional (3D) manufacturing, is the process of manufacturing a part designed in a computer environment using different types of materials such as plastic, ceramic, metal or composite. Similar to other materials, aluminum alloys are also exposed to various wear types during operation. Production efficiency needs to be aware of its reactions to wearing mechanisms.

Design/methodology/approach
In this study, quartz sands (SiO2) assisted with oxide ceramics were used in the slurry erosion test setup and its abrasiveness on the AlSi10Mg aluminum alloy material produced by the 3D printer as selective laser melting (SLM) technology was investigated. Quartz was sieved with an average particle size of 302.5 µm, and a slurry environment containing 5, 10 and 15% quartz by weight was prepared. The experiments were carried out at the velocity of 1.88 (250 rpm), 3.76 (500 rpm) and 5.64 m/s (750 rpm) and the impact angles 15, 45 and 75°.

Findings
With these experimental studies, it has been determined that the abrasiveness of quartz sand prepared in certain particle sizes is directly related to the particle concentration and particle speed, and that the wear increases with the increase of the concentration and rotational speed. Also, the variation of weight loss and surface roughness of the alloy was investigated after different wear conditions. Surface roughness values at 750 rpm speed, 10% concentration and 75° impingement angle are 0.32 and 0.38 µm for 0 and 90° samples, respectively, with a difference of approximately 18%. Moreover, concerning a sample produced at 0°, the weight loss at 250 rpm at 10% concentration and 45° particle impact angle is 32.8 mg, while the weight loss at 500 rpm 44.4 mg, and weight loss at 750 rpm is 104 mg. Besides, the morphological structures of eroded surfaces were examined using the scanning electron microscope to understand the wear mechanisms.

Originality/value
The researchers verified that this specific coating condition increases the slurry wear resistance of the mentioned steel. There are many studies about slurry wear tests; however, there is no study in the literature about the quartz sand (SiO2) assisted slurry-erosive wear of AlSi10Mg alloy produced with AM by using SLM technology. This study is needed to fill this gap in the literature and to examine the erosive wear capability of this current material in different environments. The novelty of the study is the use of SiO2 quartz sands assisted by oxide ceramics in different concentrations for the slurry erosion test setup and the investigations on erosive wear resistance of AlSi10Mg alloy manufactured by AM.

Authors: Schwaiger Katrin , Zehrer Anita , Braun Boris 
Published: December 2021

Purpose
This study targeted hospitality family business owners as essential pillars of the tourism industry. How they perceive aspects of the crisis and what they derive organizational resilience from, including the role of their human resources, are explored. Internal and external factors of resilience are analyzed alongside different levels of resilience action.

Design/methodology/approach
The World Health Organization announced coronavirus disease 2019 (COVID-19) as a pandemic on March 11, 2020. In Tirol, the hospitality industry has particularly been affected as tourism businesses find themselves in the challenging times of returning to normal business, corresponding to the fourth phase in Faulkner’s (2001) Tourism Disaster Management Framework. The authors used a qualitative exploratory approach, using semi-structured interviews.

Findings
In taking on a holistic explorative approach, the authors determined several methods used by entrepreneurs in dealing with a pandemic crisis to increase business resilience at a specific stage. Internal and external resilience factors have been detected among three levels of resilience action (personal, regional and governmental). The most surprising result of the semi-structured in-depth interviews was the entrepreneurs’ rather positive outlook.

Originality/value
Generally, this study creates an in-depth understanding of the tourism businesses in their dealing with a global crisis, using family business owners as an exemplary stakeholder group. The authors bridge a gap in the literature by applying a holistic explorative approach in the early stage of a never seen worldwide crisis and by addressing organizational resilience. Three levels of resilience action give new insight into how the beginning of a pandemic crisis is handled and perceived by hospitality family business entrepreneurs.
CloudJS: novel cloud-based design framework for text-file encryption
Authors: Gupta Rhea , Dharadhar Sara , Churi Prathamesh 
Published: December 2021

Purpose
Cloud computing is becoming increasingly popular as it facilitates convenient, ubiquitous, on-demand network access to a shared pool of configurable computing resources and applications that can be quickly retrieved and released. Despite its numerous merits, it faces setbacks in data security and privacy. Data encryption is one of the most popular solutions for data security in the cloud. Various encryption algorithms have been implemented to address security concerns. These algorithms have been reviewed along with the Jumbling Salting algorithm and its applications. The framework for using Jumbling Salting to encrypt text files in the cloud environment (CloudJS) has been thoroughly studied and improvised. The purpose of this paper is to implement the CloudJS algorithm, to discuss its performance and compare the obtained results with existing cloud encryption schemes.

Design/methodology/approach
The paper uses six research questions to analyze the performance of CloudJS algorithm in the cloud environment. The research questions are about measuring encryption time and throughput, decryption time and throughput, the ratio of cipher to the plain text of CloudJS algorithm with respect to other Cloud algorithms like AES and DES. For this purpose, the algorithm has been implemented using dockers-containers in the Linux environment.

Findings
It was found that CloudJS performs well in terms of encryption time, decryption time and throughput. It is marginally better than AES and undoubtedly better than DES in these parameters. The performance of the algorithm is not affected by a number of CPU cores, RAM size and Line size of text files. It performs decently well in all scenarios and all resultant values fall in the desired range.

Research limitations/implications
CloudJS can be tested with cloud simulation platforms (CloudSim) and cloud service providers (AWS, Google Cloud). It can also be tested with other file types. In the future, CloudJS algorithm can also be implemented in images and other files.

Originality/value
To the best of the knowledge, this is the first attempt to implement and analysis of a custom encryption algorithm (CloudJS) in the cloud environment using dockers-containers.
Differential DNA methylation across environments has no effect on gene expression in the eastern oyster
Authors: Johnson Kevin M. , Sirovy Kyle A. , Kelly Morgan W. 
Published: December 2021

Abstract

It has been hypothesized that environmentally induced changes to gene body methylation could facilitate adaptive transgenerational responses to changing environments.

We compared patterns of global gene expression (Tag‐seq) and gene body methylation (reduced representation bisulfite sequencing) in 80 eastern oysters Crassostrea virginica from six full‐sib families, common gardened for 14 months at two sites in the northern Gulf of Mexico that differed in mean salinity.

At the time of sampling, oysters from the two sites differed in mass by 60% and in parasite loads by nearly two orders of magnitude. They also differentially expressed 35% of measured transcripts. However, we observed differential methylation at only 1.4% of potentially methylated loci in comparisons between individuals from these different environments, and little correspondence between differential methylation and differential gene expression.

Instead, methylation patterns were largely driven by genetic differences among families, with a PERMANOVA analysis indicating nearly a two orders of magnitude greater number of genes differentially methylated between families than between environments.

An analysis of CpG observed/expected values (CpG O/E) across the C. virginica genome showed a distinct bimodal distribution, with genes from the first cluster showing the lower CpG O/E values, greater methylation and higher and more stable gene expression, while genes from the second cluster showed lower methylation, and lower and more variable gene expression.

Taken together, the differential methylation results suggest that only a small portion of the C. virginica genome is affected by environmentally induced changes in methylation. At this point, there is little evidence to suggest that environmentally induced methylation states would play a leading role in regulating gene expression responses to new environments.
Changes in forest structure drive temperature preferences of boreal understorey plant communities
Authors: Christiansen Ditte Marie , Iversen Lars Lønsmann , Ehrlén Johan , Hylander Kristoffer 
Published: December 2021

Abstract

The local climate in forest understories can deviate substantially from ambient conditions. Moreover, forest microclimates are often characterized by cyclic changes driven by management activities such as clear‐cutting and subsequent planting. To understand how and why understorey plant communities change, both ambient climate change and temporal variation in forest structure have to be considered.

We used inventories from 11,436 productive forest sites in Sweden repeated every 10th year 1993–2017 to examine how variation in forest structure influences changes in the average value of minimum and maximum temperature preferences of all species in a community, that is, community temperature indices (CTIs). We then evaluated to what extent these changes were driven by local extinctions and colonizations, respectively, and to what extent the difference in CTI value between two inventories was related to changes in forest density and in macroclimate. Lastly, we tested whether effects on CTI change by these two drivers were modified by topography, soil moisture and tree species composition.

CTI values of the understorey plant communities increased after clear‐cutting, and decreased during periods when the forest grew denser. During the period immediately after clear‐cutting, changes were predominately driven by colonizations of species with a preference for higher temperatures. During the forest regeneration phase, both colonizations by species preferring lower temperatures and local extinctions of species preferring higher temperatures increased. The change in understorey CTI over 10‐year periods was explained more by changes in forest density, than by changes in macroclimate. Soil moisture, topography and forest tree species composition modified to some extent the effects of changes in forest density and in macroclimate on understorey CTI values.

Synthesis. Via stand manipulation, forest management impacts the effects of regional climate on understorey plant communities. This implies that forest management by creating denser stands locally even can counterbalance the effects of regional changes in climate. Consequently, interpretations of changes in the mean temperature preference of species in forest understorey communities should take forest management regimes into account.

AbstractObjectiveCervical cancer screening guidelines have evolved over time with the incorporation of human papillomavirus (HPV) testing along with cytology. Current screening guidelines recommend cytological screening every 3 years or HPV testing with or without cytology every 5 years in women age 30–65 years. We examined the use of cervical cancer screening among average‐risk Medicaid beneficiaries.DesignRetrospective cohort study.PopulationWomen age 30–64 years at average risk for cervical cancer who underwent cervical cancer screening with cytology, co‐testing or primary HPV testing from 2013 to 2016.MethodsThe IBM Watson Health Multi‐State Medicaid MarketScan Database was used. Subsequent screening rates within 3 years of the index test were examined.Main outcome measureThe rate of repeat cervical cancer screening was analysed using a cumulative incidence function.ResultsA total of 265 083 patients were identified. Overall, 43.1% (n = 114 312) had index co‐testing, 55.2% (n = 146 309) had cytology and 1.7% (n = 4462) had primary HPV testing. The cumulative incidence of early, repeat cervical cancer screening was 3.9% at 12 months, 22.7% at 24 months and 33.3% at 36 months. During the period from 12 to 24 months after follow up, 20.9% of women underwent repeat screening while 19.4% underwent repeat screening 24–36 months after the index test. Among women who did not undergo repeat cervical cancer screening, a yearly gynaecological examination was performed in only 16 627 (10.7%) during year 2 and in 11 116 (8.8%) during year 3.ConclusionAmong average‐risk Medicaid beneficiaries, cervical cancer screening is frequently overused. Women who do not undergo cervical cancer screening are unlikely to undergo routine gynaecological examination.Tweetable AbstractAmong average‐risk Medicaid beneficiaries, cervical cancer screening is frequently overused.

AbstractBackgroundStudies on the application of targeted therapies for patients with non‐small cell lung cancer (NSCLC) who harbor rare genetic mutations are ongoing. In the present study, we investigated the real‐world data of NSCLC patients who harbor rare mutations.MethodsWe retrospectively analyzed patients with advanced or metastatic nonsquamous NSCLC aged >20 years with confirmed rare mutations (BRAF, ROS1, MET, RET, HER2, FGFR, and NTRK) from January 2015 to September 2020 at nine tertiary hospitals. In addition, we validated the lung cancer PCR panel kit in patients with confirmed mutations by NGS.ResultsAmong 118 patients included, 88 received platinum‐based chemotherapy as first‐line chemotherapy. The progression‐free survival of patients with BRAF, ERBB2, MET, RET, and ROS1 mutations was 10.9 months (95% confidence interval [CI]: 1.3–20.5), 5.3 months (95% CI: 3.0–7.5), 7.2 months (95% CI: 3.6–10.9), 11.4 months (95% CI: 9.2–13.6), and 10.0 months (95% CI: 3.7–16.4) respectively (p = 0.041). The median overall survival (OS) was not reached in patients with ROS1 mutations; however, in BRAF, ERBB2, MET, and RET mutant patients, median OS was 14.1 months (95% CI: 10.1–14.1), 34.5 months (95% CI: 13.2–36.9), 22.7 months (95% CI: 1.7–24.0), and 29.8 months (95% CI: 28.9–61.3), respectively (p = 0.006). Of the 27 tissue samples, 26 (96.3%) showed the same PCR panel kit result with NGS.ConclusionsFirst‐line platinum‐based chemotherapy showed durable benefit in patients with advanced or metastatic nonsquamous NSCLC harboring rare genetic mutation other than EGFR or ALK.

AbstractBackground and aimsBlack adults who smoke are less likely to seek treatment and to succeed in quitting compared with other racial groups. The lack of efficacious and engaging trials for smoking cessation further contributes to this disparity. This study explored whether an acceptance and commitment therapy (ACT)‐based smartphone application (iCanQuit) was more efficacious for smoking cessation than a United States Clinical Practice Guidelines (USCPG)‐based smartphone application (QuitGuide) among Black adults.DesignSecondary analysis of a two‐arm randomized trial with 12‐month follow‐up.SettingUnited States (US).ParticipantsA total of 554 Black adults who smoke daily were recruited from 34 US states and enrolled between May 2017 and September 2018.InterventionsParticipants were randomized to receive iCanQuit (n = 274) or QuitGuide (n = 280) for 12 months.MeasurementsSmoking cessation outcomes were measured at 3, 6, and 12 months. The primary outcome was self‐reported complete‐case 30‐day point prevalence abstinence (PPA) at 12 months. Secondary outcomes were 7‐day PPA, missing‐as‐smoking imputation, multiple imputation, prolonged abstinence, and cessation of all tobacco products at 12 months. Study retention, treatment engagement, and change in ACT‐based processes were also compared between arms.FindingsStudy retention was 89% at 12 months and did not differ by arm (P > 0.05). The complete‐case 30‐day PPA was 28% for iCanQuit versus 20% for QuitGuide at 12 months (odds ratio [OR] = 1.60; 95% confidence interval [CI] = 1.03, 2.46). Similar associations were observed for the missing‐as‐smoking imputation, although non‐significant (25% iCanQuit vs 18% QuitGuide; OR = 1.50; 95% CI = 0.98, 2.30). iCanQuit vs QuitGuide participants were significantly more engaged with iCanQuit application as measured by the number of logins from baseline to 6 months (incidence rate ratio = 3.26; 95% CI = 2.58, 4.13). Increased acceptance of cues to smoke mediated the effect of treatment on cessation (indirect effect: OR = 0.20; 95% CI = 0.05, 0.29).ConclusionsAmong Black adults, an acceptance and commitment therapy‐based smartphone application appeared to be more efficacious and engaging for smoking cessation than the United States Clinical Practice Guidelines‐based QuitGuide application.

AbstractPurposeTo investigate the response of the superficial and deep capillary plexuses to hyperoxia and hypoxia using optical coherence tomography angiography (OCT‐A) and retinal vessel analyzer.MethodsTwenty‐four healthy volunteers participated in this randomized, double‐masked, cross‐over study. For each subject, two study days were scheduled: on one study day, hyperoxia was induced by breathing 100% oxygen whereas on the other study day, hypoxia was induced by breathing a mixture of 88% nitrogen and 12% oxygen. Perfusion density was calculated in the superficial vascular plexus (SVP) and the deep capillary plexus (DCP), using OCT‐A before (normal breathing) and during breathing of the gas mixtures. Retinal vessel calibres in major retinal vessels were measured using a dynamic vessel analyzer.ResultsDuring 100% oxygen breathing, a significant decrease in DCP perfusion density from 41.7 ± 2.4 a.u to 35.6 ± 3.1 a.u. (p < 0.001) was observed, which was accompanied by a significant decrease in vessel diameters in major retinal arteries and veins (p < 0.001 each). No significant change in perfusion density in the SVP occurred (p = 0.33). In contrast, during hypoxia, perfusion density in the SVP significantly increased from 34.4 ± 3.0 a.u. to 37.1 ± 2.2 a.u. (p < 0.001), while it remained stable in the DCP (p = 0.25). A significant increase in retinal vessel diameters was found (p < 0.01). Systemic oxygen saturation correlated negatively with perfusion density in the SVP and the DCP and retinal vessel diameters (p < 0.005 each).ConclusionOur results show that systemic hyperoxia induces a significant decrease in vessel density in the DCP, while hypoxia leads to increased vessel density limited to the SVP. These results indicate that the retinal circulation shows the ability to adapt its blood flow to metabolic changes with high local resolution dependent on the capillary plexus.
