Core elements and potential of nurse‐led care models in residential long‐term care: A scoping review
Authors: Schmüdderich Kathrin , Kiwitt Jörn , Palm Rebecca , Roes Martina , Holle Bernhard
Published: February 2022

Aims and objective

To identify and summarise core elements, resident‐, staff‐ and process‐related outcomes and challenges of nurse‐led care models in residential long‐term care.

Background

Due to demographic trends, the complexity of residential long‐term care has increased. To address this complexity, the implementation of nurse‐led care models has been recommended.

Design

Scoping review.

Methods

A systematic search was conducted of English and German articles in CINAHL via EBSCO, MEDLINE via PubMed, Cochrane Library and Scopus. Forward and backward citation tracking via reference lists and Google Scholar supplemented the search. The final update was made on 19 January 2021. To draw conclusions about the potential of nurse‐led care models, evaluation studies of the described models for residents in nursing homes were included. Full texts were independently screened and assessed for methodological quality. Data were extracted and summarised in tables and synthesised for analysis. The core elements of the models were described using the Sustainable intEgrated chronic care modeLs for multimorbidity: delivery, FInancing and performancE (SELFIE) framework. The review followed the PRISMA‐ScR guideline.

Results

We included 13 studies of 12 nurse‐led care models. The different models comprised many of the core elements suggested in the SELFIE framework, particularly in the components service delivery, workforce, and leadership and governance. The studies reported a broad range of resident‐, staff‐ and process‐related outcomes and challenges considered relevant to the success of the models.

Conclusions

Studies evaluating nurse‐led care models in nursing homes are limited and of moderate quality. This review demonstrates that nurse‐led care models include many elements for care coordination and could improve resident‐, staff‐ and process‐related outcomes.

Relevance to clinical practice

This review highlights that nurse‐led care models share common core elements despite their heterogeneity. It also shows that highly qualified nurses in nurse‐led care models can advance nursing practice in nursing homes.
Broadening our understanding of interfirm rivalry: A call for research on how supply networks shape competitive behavior and performance
Authors: Hofer Christian , Barker Jordan M. , D'Oria Laura , Johnson Jonathan L.
Published: February 2022

In their pursuit of greater performance, firms invariably compete with their rivals for customer demand or scarce resources in factor markets. Firms' competitive behavior—the series of competitive actions taken to create or maintain competitive advantage—thus, is a key predictor of profitability and has received much attention in the strategic management literature. The central tenet of this article is that supply networks and the relationships among firms in these networks fundamentally shape the nature of interfirm competition and, ultimately, firm performance. Although prior research has amply studied the competitive dynamics among (horizontal) rival firms as well as the linkages between supply network characteristics and firm performance, there remain important opportunities to examine how supply networks enable and shape firms' competitive behavior and the effectiveness of their rivalrous activity. The goal of this article, therefore, is to take stock of the advances made in prior literature and to outline topics for future study at the intersection of competition and supply chain management. Collectively, we lay out a comprehensive perspective on the role that supply networks can play in affecting competition that, we hope, will inform and guide efforts to enhance our understanding of firm‐level competitive behavior and associated performance outcomes.

Published: February 2022

Background and Aim

Polycystic liver disease (PLD) is related to hepatomegaly which causes an increased mechanical pressure on the abdominal wall. This may lead to abdominal wall herniation (AWH). We set out to establish the prevalence of AWH in PLD and explore risk factors.

Methods

In this cross‐sectional cohort study, we assessed the presence of AWHs from PLD patients with at least 1 abdominal computed tomography or magnetic resonance imaging scan. AWH presence on imaging was independently evaluated by two researchers. Data on potential risk factors were extracted from clinical files.

Results

We included 484 patients of which 40.1% (n = 194) had an AWH. We found a clear predominance of umbilical hernias (25.8%, n = 125) while multiple hernias were present in 6.2% (n = 30). Using multivariate analysis, male sex (odds ratio [OR] 2.727 p < .001), abdominal surgery (OR 2.575, p < .001) and disease severity according to the Gigot classification (Type 3 OR 2.853, p < .001) were identified as risk factors. Height‐adjusted total liver volume was an independent PLD‐specific risk factor in the subgroup of patients with known total liver volume (OR 1.363, p = .001). Patients with multiple hernias were older (62.1 vs. 55.1, p = .001) and more frequently male (22.0% vs. 50.0%, p = .001).

Conclusion

AWHs occur frequently in PLD with a predominance of umbilical hernias. Hepatomegaly is a clear disease‐specific risk factor.
The carbon economics of vegetative phase change
Authors: Lawrence Erica H. , Springer Clint J. , Helliker Brent R. , Poethig R. Scott
Published: February 2022

Across plant species and biomes, a conserved set of leaf traits govern the economic strategy used to assimilate and invest carbon. As plants age, they face new challenges that may require shifts in this leaf economic strategy. In this study, we investigate the role of the developmental transition, vegetative phase change (VPC), in altering carbon economics as plants age. We used overexpression of microRNA 156 (miR156), the master regulator of VPC, to modulate the timing of VPC in Populus tremula x alba, Arabidopsis thaliana and Zea mays to understand the impact of this transition on leaf economic traits, including construction cost, payback time and return on investment. Here, we find that VPC causes a shift from a low‐cost, quick return juvenile strategy to a high‐cost, high‐return adult strategy. The juvenile strategy is advantageous in light‐limited conditions, whereas the adult strategy provides greater returns in high light. The transition between these strategies is correlated with the developmental decline in the level of miR156, suggesting that is regulated by the miR156/SPL pathway. Our results provide an ecophysiological explanation for the existence of juvenile and adult leaf types and suggest that natural selection for these alternative economic strategies could be an important factor in plant evolution.
Insufficient hepatic uptake in pediatric patients on lymphoscintigraphy
Authors: Hosokawa Takahiro , Uchiyama Mayuki , Tanami Yutaka , Sato Yumiko , Wakabayashi Yasuharu , Oguma Eiji
Published: February 2022

Background

To demonstrate the association between pediatric outcomes and tracer hepatic uptake as a marker of systemic circulation in lymphoscintigraphy.

Methods

We included 31 initial lymphoscintigraphic studies. We compared the presence or absence of hepatic uptake between deceased and survived patients in both early and delayed images using Fisher's exact test. Kaplan–Meier survival analysis was performed based on imaging results, and these curves were compared using the log‐rank test. The primary endpoint was death and the survival period was defined from the day of examination to the day of the last visit or death.

Results

Of 31 patients, six died. Hepatic uptake was significantly different in both early and delayed images (early images, died [with/without visualization] vs. survived [with/without visualization], 0/6 vs. 13/12, P = 0.028; delayed images, died [with/without visualization] vs. survived [with/without visualization], 2/4 vs. 22/3, P = 0.014) between deceased and survived patients. Survival periods were significantly different between the two groups with and without hepatic uptake in early and delayed images (with/without visualization in early imags = 1,177.1 ± 773.8 days/426.7 ± 419.8 days, P = 0.008 and with/without visualization in delayed images = 821.3 ± 738.0 days/467.4 ± 452.4 days, P = 0.003).

Conclusions

Visualization of hepatic uptake in both early and delayed lymphoscintigraphy is associated with patient outcomes. Hepatic uptake could represent tracer inflow into the systemic circulation, indicating preservation of the connection between the lymphatic system and the systemic circulation. Physicians should evaluate these findings carefully on lymphoscintigraphy.

Published: February 2022

Objective

To understand communities’ perceptions, beliefs, and health‐related behavior choices related to COVID‐19 in order to guide public health nursing communication and interaction with patients and the community.

Design

A qualitative study, guided by the Health Belief Model (HBM), strove to comprehend the perceptions and reactions to COVID‐19 among Wisconsinites.

Sample

Twenty‐five diverse Wisconsin residents aged 18 or older.

Measurements

Semi‐structured interviews provided information about individuals’ attitudes, perceptions, and reactions to COVID‐19. Interviews were audio‐recorded, transcribed, and thematic analysis was conducted to identify themes.

Results

We identified three major themes: (1) “health care starts way before you ever enter the doors of a healthcare facility”; (2) “to live in a society is to help each other”; and (3) mental health as impacted by COVID‐19.

Conclusions

This study demonstrated the need for greater public health support, as well as the role of Social Determinants of Health. Understanding perceptions and reactions to COVID‐19 can help public health nurses understand and better respond to future pandemics.

Authors: Ojeda‐Morales Marcia E. , Domínguez‐Domínguez Marivel , Herrera‐Haro José G. , Hernández‐Rivera Miguel A. , Córdova‐Bautista Yolanda , Martínez‐Zurimendi Pablo
Published: February 2022

Mangrove forests are ecosystems subject to contamination by oil spills. The objective of this study was to evaluate the development of Rhizophora mangle plants in soil contaminated with oil emulsified with surfactants. These ecosystems have diverse and economically valuable ecological functions. Mangrove soil and propagules were collected in southeastern Mexico. The propagules were sown under greenhouse conditions and the plants were grown for 3 months. Two bioassays were applied: (1) the soil was contaminated by oil emulsified with a biosurfactant synthesized by Azospirillum lipoferum, and (2) the soil was contaminated with oil emulsified with a surfactant based on pine essential oil. Emulsified oil was applied to the substrate in containers with 3‐month‐old plants until several concentrations were reached (0, 30,000, 40,000, 50,000, 60,000, and 70,000 ppm). Subsequently, 5 plants for each treatment were randomly extracted every 30 days for 12 months, and the stem length and diameter, root length, leaf area, and fresh and dry weights of the plants were evaluated. Plant development was evaluated through an analysis of variance and a test of means. At the end of the bioassay, the treatments with oil emulsified with pine oil yielded no surviving plants, whereas the treatments with oil emulsified with the biosurfactant yielded a 100% survival rate. Treatment with 30,000 ppm of oil emulsified with the biosurfactant yielded the greatest increases in the leaf area and total dry biomass. The heavy oil fraction concentration decreased by 93.9% with the 30,000 ppm treatment and by 82.64% with the 70,000 ppm treatment.
Different encounter behaviors: Businesses in encounters with regulatory agencies
Authors: Nielsen Helle Ørsted , Nielsen Vibeke Lehmann
Published: February 2022

Studies on regulatory encounters have shown that the interaction between regulator and regulatee is important for implementation of public policy. Much of this research examines how the behavior of frontline workers in such encounters affects regulateecompliance, that is, an outcome of the encounter, but we know less about thebehaviorthat regulatees bring to these encounters. This paper therefore examines how businesses behave in encounters with regulatory authorities, and whether we can identify distinct, multidimensional types of encounter behavior. Using survey data from representative samples of Danish businesses and an exploratory cluster analysis, we identify five types of encounter behavior. We label these “Cooperators,” “Accommodators,” “Game players,” “Protesters,” and “Fighters.” We believe this framework provides a useful next step in a research agenda on businesses' behavior in regulatory encounters.
Microfinance and poverty reduction: Evidence from Djibouti
Authors: Abdallah Ali Mohamed , Mughal Mazhar , Chhorn Dina
Published: February 2022

Does access to microfinance improve household welfare? We seek the answer to this question using data on 2,060 borrower and nonborrower households based in six major urban centers of Djibouti. We construct a composite index of multidimensional poverty that captures various aspects of household well‐being, including ownership of agricultural and livestock assets, land, transportation, employment, quality of housing, and sanitation facilities. We carry out estimations using an instrumental variable–based empirical strategy and a number of econometric techniques. Our results show that neither access to microcredit nor its ostensibly productive use is significantly associated with poverty regardless of the duration of time since the loan was acquired. This holds for both access to and the amount of microcredit obtained. The results are robust across specifications and econometric techniques employed. The lack of significant beneficial effect of microfinance found in the study adds to the growing literature questioning the effectiveness of microfinance as a tool for poverty alleviation. The findings raise doubts on the usefulness of Djibouti's microfinance program.
Scaling up civic food utopias in Australia: The challenges of justice and representation
Authors: Smith Kiah
Published: February 2022

Through the lens of food utopias, this article explores the opportunities and dilemmas experienced by selected civic food networks (CFNs) in Australia as they seek to scale‐up from local initiatives, to regional coalitions, to national social movements. Findings from qualitative analysis of key informant interviews indicate the ways that scaling up is both a micro‐ and macro‐level process. While local initiatives focus on different problems (food waste, hunger, health, ecology), establishing shared visions that emphasise systems reform has shaped coalition building and collective action beyond the local. As problem and solution definitions converge and diverge around justice and rights, however, limitations in the representation, positioning and ‘voice’ of marginalised stakeholders – specifically, indigenous people and those most affected by hunger – have emerged. This has opened up new spaces of contestation that today take central place in determining the trajectory of ‘values‐based territorial food networks’ in Australia.
Cytologic diagnosis of Mycoplasma in a recurrent abscess from a cat
Authors: Obeiter Sara T. , Sneed Amy , Odemuyiwa Solomon O. , Royal Angela
Published: February 2022

A 10‐year‐old, neutered male, indoor/outdoor domestic shorthair cat was presented for a mass on the right front paw. The mass was treated as an abscess, and despite initial resolution, the mass recurred and ruptured approximately 1 month later. This mass successfully resolved with intense management as an open wound. Several days later, the cat developed vomiting and inappetence, and a new mass was noted on the lateral aspect of the right rear limb. Aspirates from the new mass were submitted for cytologic evaluation and bacterial cultures. Anaerobic and aerobic bacterial cultures were negative. Cytologic evaluation revealed septic neutrophilic inflammation with small rod, cocci, curved, and ring forms of bacteria seen, and Mycoplasma spp. infection was suspected based on the morphology of the bacteria. Polymerase chain reaction followed by gene sequencing revealed 86% similarity for Mycoplasma elephantis. The cat was treated with a fluoroquinolone antibiotic and clinically improved, with resolution of the abscess. This case highlights the importance of recognizing the morphologic appearance of Mycoplasma spp. on cytologic examination to help guide additional testing choices and therapeutic planning.
Diplomatic Ceremonial as the Basis of the Culture of International Relations
Authors: Zakharova Oksana
Published: February 2022

Currently, there is an increased interest in the ceremonial culture in general, and in etiquette as a component of the ceremonial, in particular. This phenomenon is largely explained by their special role in the processes of communication in society, as well as a new understanding of the processes of communication and behaviour themselves. A ceremonial is a kind of cultural message from one social group of people to another. The basic idea of behaviour, the inner meaning of secular ceremonial is laid down in church rituals, and external forms of behaviour can be borrowed from the traditions of everyday secular life. The relevance of the study is determined by insufficient knowledge of diplomatic ceremonies of The Union of Soviet Socialist Republics, and the fact that knowledge of the laws of their functioning expands the understanding of domestic politics and international relations of the era, the cultural component of the life of Soviet society. The socio-cultural aspect of the topic is also relevant in scientific terms. This research can contribute to the study of the history of the organisational culture of Soviet society. Taking into account the absence of a special study devoted to the problem in historiography, the purpose of the article is to conduct a comprehensive study of the communicative functions of diplomatic ceremonial in international communication based on the analysis and generalisation of new facts with the involvement of archival materials and other sources introduced into scientific circulation for the first time. In this study, art is considered for the first time from the point of view of the communicative factor of diplomatic ceremonial. For the first time, such a term as "diplomatic counterculture" is introduced into circulation.

associated with verbal and non-verbal communication. The purpose of the article is to study the discursive and communicative-pragmatic nature of poetical images of silence in the English-language literary discourse. The universal and cultural functions of this notion were analysed and the main approaches to the poetical silence study were determined. It became clear that the phenomenon of Nature Silence can be actualised with the help of Nature and other landscape images in the field of English literary discourse. Such images must belong to the paradigm of English landscape images represented by Earthy, Aerial and Celestial substantial nature symbols. In terms of discourse-communicative approach to the study of communicative silence, these elements play an important role of the main producers of Nature Silence. This work proposes the new pragmatic and communicative approach of understanding the Nature silence in English literary discourse. The main verbal units that can actualise the poetical image of silence are characterised by the permanent correlation with the different symbols of nature, showing the dominant and peripheral characteristics. Being the pragmatic realisation of silence image, motives of Nature Silence may be considered both as dominant and background.

Published: February 2022

A 49-year-old man was involved in a high-energy motor vehicle accident. Haemodynamic instability with multiple long bone fractures of lower limbs was the hallmarks of the injury. Closed fragmented fracture of left femur shaft and open displaced supracondylar fracture of the contralateral femur. Closed comminuted high-grade fracture of the Tibia plateau (Schatzker VI) was diagnosed bilaterally. ‘Orthopaedic damage control’ was initiated with bilateral ‘cross knee’ external fixation, followed by conversion to open reduction internal fixation of all fracture sits at 8 days later. The patient underwent nine subsequent hospitalisations, of which eight involved operative treatment. The interval from admission to last documented surgery was 7 years. The endpoint was total knee arthroplasty (TKA) with mega prosthesis of the left knee and a primary-type TKA in the right knee. Both arthroplasties were non-assisted, conventional procedures. Postoperative Western Onterio and McMaster Universities Arthritis Index (WOMAC) score was 85 at 9-year follow-up from the injury incurred.

Published: February 2022

Poor sanitation and contaminated food and water are major risk factors for several infectious diseases like enteric fever and hepatitis A, but their coinfection is uncommon. Although the liver is frequently affected in typhoid fever, substantial hepatic dysfunction in an appropriately treated patient is uncommon. Our patient had high-grade fever with mild transaminitis and blood culture that grewSalmonella typhi. Despite being treated with culture-sensitive antibiotic at adequate dosage, he developed jaundice and had worsening transaminitis (>1000 IU/L) which was suggestive of hepatotropic virus infection. Hepatitis A IgM was positive. He was treated appropriately with which clinical and laboratory parameters resolved.

We investigate the sensitivity of solar neutrino data to mixing of sterile neutrinos with masses $$\gtrsim $$
≳
 eV. For current data, we perform a Feldman–Cousins analysis to derive a robust limit on the sterile neutrino mixing. The solar neutrino limit excludes significant regions of the parameter space relevant to hints from reactor and radioactive gallium source experiments. We then study the sensitivity of upcoming solar neutrino data, most notably elastic neutrino-electron scattering in the DARWIN and DUNE experiments as well as coherent neutrino-nucleus scattering in DARWIN. These high precision measurements will increase the sensitivity to sterile neutrino mixing by about a factor of 4.5 compared to present limits. As a by-product, we introduce a simplified solar neutrino analysis using only four data points: the low- and high-energy $$\nu _e$$

Note on stability and holographic subregion complexity
Authors: Ali-Akbari Mohammad , Lezgi Mahsa
Published: February 2022

We study holographic subregion complexity in a spatially anisotropic field theory, which expresses a confinement-deconfinement phase transition. Its holographic dual is a five-dimensional anisotropic holographic model characterized by a Van der Waals-like phase transition between small and large black holes. We propose a new interpretation from the informational perspective to determine the stable and unstable thermodynamically solutions. According to this proposal, the states which need (more) less information to be specified characterize the (un) stable solutions. We similarly offer an interpretation to determine the stable and unstable solutions based on the resource of a computational machine, such that the solutions are (un) stable if computational resource (decreases) increases with the increase of temperature. We observe that the effect of anisotropy on holographic subregion complexity is decreasing. This decreasing effect can be interpreted by considering a whole closed system consisting of the state and its environment in which the complexity of the mixed state decreases and complexity of the environment increases.

ENERGY FINANCING, COVID-19 REPERCUSSIONS AND CLIMATE CHANGE: IMPLICATIONS FOR EMERGING ECONOMIES
Authors: ZHAO LINHAI , SAYDALIEV HAYOT BERK , IQBAL SAJID
Published: February 2022

This study is intended to test the role of renewable energy financing on climate change and to present the implications for the key stakeholders towards the acquisition of post-covid-recovery in the Asian and ASEAN economies. For this, data envelopment analysis (DEA) technique is applied to draw an inference between the constructs. Study finding resulted that higher energy consumption and rise in environmental pollution has brought a great change in the ASEAN and Asian economies’ climate, for which, modern and renewable energy sources are suggested to use for the climate change mitigation. A sufficient amount of funds and the supply of energy finance to mitigate the climate change are eminently needed for the post-covid-recovery. Different financial institutions, banks and finance ministries of countries belonging from the both regions are suggested to play the best role. This is solely possible by pooling the funds in renewable energy sectors to enhance energy efficiency and control the climate change. This must be executed for the long-run period to get the desired outcomes. All the countries of both regions are further suggested to expedite the practices to apply strategic development goals (SDGs) for affordable and clean energy (SDG–7), climate change action (SDG–13) to achieve the national and global strategic objectives.

Published: February 2022

This paper intends to describe a procedural framework for identifying the operations strategy efficiency frontier and, based on this, establish initiatives to improve a given company’s competitiveness position. Each step of the framework is explained, including recommendations on how results should be interpreted. Empirical data are used to exemplify the implementation of the procedural framework. The process contributes to knowledge on the current needs, thereby supporting agile decision making. The contribution also enables dynamic mapping the competitive environment, enabling an current picture of the industry’s competitive context and supporting the establishment of emerging strategies. Two literature gaps are covered: first the lack of focus on identifying the performance frontier process within the context of operations strategy and second, the deployment of the competitive priorities in a market-based view approach.
Image and Video Coding Techniques for Ultra-low Latency
Authors: Žádník Jakub , Mäkitalo Markku , Vanne Jarno , Jääskeläinen Pekka
Published: February 2022

The next generation of wireless networks fosters the adoption of latency-critical applications such as XR, connected industry, or autonomous driving. This survey gathers implementation aspects of different image and video coding schemes and discusses their tradeoffs. Standardized video coding technologies such as HEVC or VVC provide a high compression ratio, but their enormous complexity sets the scene for alternative approaches like still image, mezzanine, or texture compression in scenarios with tight resource or latency constraints. Regardless of the coding scheme, we found inter-device memory transfers and the lack of sub-frame coding as limitations of current full-system and software-programmable implementations.

A Study on Disabling Injuries Prediction of Taiwan Occupational Disaster with Grey Rolling Model
Authors: Ho Chun-Ling , Lin Yu-Sheng
Published: February 2022

In order to protect the safety and health of laborers and to achieve the goal of zero occupational accidents at work, the study takes the top three industries with the highest number of laborers inspections from 2010 to 2019, namely, construction, manufacturing, wholesale, and retail as the research object. Using three major indicators of disability injury including Disabling Frequency Rate, Disabling Severity Rate, and Frequency Severity Indicator as parameters, it applies grey theory to establish a GM (1,1) rolling forecast model. It further predicts the trend of disability injuries from 2020 to 2025. Based on the optimized GM (1,1) rolling model, the results show that there has the highest accuracy rate in the prediction of Disabling Frequency Rate (accuracy is 95.235% in K7) in construction. Disabling Severity Rate and Frequency Severity Indicator are both in wholesale and retail industries (accuracy is 97.044% in K6 and accuracy is 99.906% in K5). Therefore, Disabling Severity Rate has an upward trend, which is due to the common type of traffic accidents in the wholesale and retail industry. The study further proposes that relevant actual disaster cases could be the training materials and strengthen the communication in education to improve workers’ safety awareness for occupational disaster prevention.

Background. To investigate the significance of echocardiography combined with N-terminal pro-B-type natriuretic peptide (NT-pro BNP) levels in the evaluation and prognosis of diastolic heart failure (DHF). Methods. Clinical data were collected from 168 patients with DHF. Serum levels of NT-pro BNP were first measured by ELISA. Meanwhile, the echocardiography was used to examine left ventricular end-diastolic diameter (LVEDD), left ventricular diameter (LVD), and other parameters. Multivariate logistic regression analysis was performed for variables in heart failure assessment grade or poor prognosis. Finally, the predictive ability for New York Heart Association (NYHA) class as well as prognosis was assessed by ROC curves. Results. NT-pro BNP was the overexpression in the serum of patients with DHF. And the degree of elevation was related to NYHA class, while NT-pro BNP levels were significantly higher in the P-MACE group than in the N-MACE group. According to the multivariate logistic regression analysis, the ratio of peak velocity of left atrial early diastolic blood flow to early diastolic peak velocity of mitral annulus (

E

/Ea) and serum NT-pro BNP level was risk factors for NYHA class and prognosis. However, LVEF, LVEDD, and flow propagation velocity (Vp) can be a benefit condition. In addition, ROC curve showed that echocardiography combined with NT-pro BNP content had higher accuracy in NYHA class and prognostic assessment of DHF than applied separately. Conclusions. The diagnosis of echocardiography combined with NT-pro BNP levels has the potential to distinguish the NYHA class in heart function of patients with DHF and determine the prognosis of patients.

Coal and rock are often in an environment of hydraulic-mechanical coupling. In order to study the failure mechanism of the coal-rock combined body under the coupling action of hydraulic and mechanical, the RFPA-Flow software was used to analyze the failure mode, strength change law, and acoustic emission change law of the coal-rock combined body with different rock-to-coal height ratios under the combined action of uniaxial load and water pressure. The research results show that the peak strength, residual strength, and stress drop of coal-rock combined body with different rock-to-coal height ratios decrease after water pressure, which reduces the occurrence probability of rock bursts. However, the stress showed a vertical drop phenomenon in the later stage of loading, indicating that the coal-rock combined body still maintains the characteristics of brittle failure after being softened by water, and the roadway may still have rock bursts. The research conclusions can provide a theoretical basis for using water injection measures to prevent rock bursts in deep coal and rock masses.
Certificateless Reliable and Privacy-Preserving Auditing of Group Shared Data for FOG-CPSs

FOG-enabled cyber-physical systems (FOG-CPSs) open new security challenges as the local edge devices are easier to compromise than a traditional cloud server. Remote data integrity checking (RDIC) plays an important role in safeguarding against data corruption from a storage server. Certificateless cryptography (CLPKC)-based RDIC schemes do not suffer from the drawbacks of the public key infrastructure (PKI)-based RDIC protocols. Most of the CLPKC-based RDIC schemes proposed in the literature deal with personal data. However, in a FOG-CPS, it is also important to audit a data file shared by a group of edge devices. Most of the existing group shared data auditing schemes lack mechanisms to defend against a semi-trusted data auditor applicable for a FOG-CPS scenario. In order to address these issues, in this paper, we propose a novel CLPKC-based group shared data auditing protocol tailored to the specific security requirements of a FOG-CPS. Besides, we perform a detailed cryptanalysis of two existing CLPKC-based privacy-preserving group shared data auditing schemes. The formal security analysis of our proposed protocol establishes metadata and data integrity proof unforgeability and claimed zero-knowledge privacy and reliability properties through rigorous proofs in the random oracle model setting. Performance evaluations establish the efficiency of our proposed protocol.

Individuals with chronic lymphocytic leukemia (CLL) have significant immune disfunction, often further disrupted by treatment. While currently available COVID-19 vaccinations are highly effective in immunocompetent individuals, they are often poorly immunogenic in CLL patients. It is important to understand the role a heterologous boost would have in patients who did not respond to the initial two-dose mRNA vaccine series. SARS-CoV-2 specific immune responses, including antibodies and memory B-cells, CD4 and CD8 T-cells were assessed prior to vaccination, as well as postinitial vaccination series and post-third dose in two subjects. One subject seroconverted, had RBD-specific memory B-cells and spike-specific CD4 T-cells while the other did not. Both subjects had a spike-specific CD8 T-cell response after the original mRNA vaccination series that was further boosted after the third dose or remained stable. The results of this study, however small, are especially promising to CLL individuals who did not seroconvert following the initial mRNA vaccination series.

Image fusion can be performed on images either in spatial domain or frequency domain methods. Frequency domain methods will be most preferred because these methods can improve the quality of edges in an image. In image fusion, the resultant fused images will be more informative than individual input images, thus more suitable for classification problems. Artificial intelligence (AI) algorithms play a significant role in improving patient’s treatment in the health care industry and thus improving personalized medicine. This research work analyses the role of image fusion in an improved brain tumour classification model, and this novel fusion-based cancer classification model can be used for personalized medicine more effectively. Image fusion can improve the quality of resultant images and thus improve the result of classifiers. Instead of using individual input images, the high-quality fused images will provide better classification results. Initially, the contrast limited adaptive histogram equalization technique preprocess input images such as MRI and SPECT images. Benign and malignant class brain tumor images are applied with discrete cosine transform-based fusion method to obtain fused images. AI algorithms such as support vector machine classifier, KNN classifier, and decision tree classifiers are tested with features obtained from fused images and compared with the result obtained from individual input images. Performances of classifiers are measured using the parameters accuracy, precision, recall, specificity, and

1 score of 91%, and performed better than KNN and decision tree classifiers when extracted features from fused images are used. The proposed method results are compared with existing methods and provide satisfactory results.

Mapping knowledge domain (MKD) is an important application in bibliometrics, which is a method of visually presenting and explaining newly developed interdisciplinary scientific fields using data mining, information analysis, scientific measurement, and graphic rendering. This study combines applied mathematics, visual analysis technology, information science, and scientometrics to systematically analyze the development status, research distribution, and future trend of the heterogeneous traffic flow by using the MKD software tools VOSviewer and CiteSpace. Based on the MKD and Bibliometrics approaches, 4709 articles have been studied, which were published by Science Citation Index Expanded (SCIE) and Social Sciences Citation Index (SSCI) from 2004 to 2021 in the field of heterogeneous traffic flows. Firstly, this paper presents the annual numbers of articles, origin countries, main research organizations, and groups as well as the source journals on heterogeneous traffic flow studies. Then, cocitation analysis is used to divide heterogeneous traffic flow into three main research directions, which include “heterogeneous traffic flow model,” “traffic flow capacity analysis,” and “traffic flow stability analysis.” The keyword cooccurrence analysis is applied to identify five dominant clusters: “modeling and optimization methods,” “traffic flow characteristics analysis,” “driving behavior analysis,” “simulation experiment,” and “policies and barriers.” Finally, burst keywords were studied according to the publication date to present more clearly the change of research focus and direction over time.
