Compact Broadband Antenna with Vicsek Fractal Slots for WLAN and WiMAX Applications

This paper aims to design a compact broadband antenna for wireless local area network (WLAN) and worldwide interoperability for microwave access (WIMAX) applications. The suggested antenna consists of an octagonal radiator with Vicsek fractal slots and a partial ground plane, it is printed on FR-4 dielectric substrate, and its global dimension is 50 × 50 × 1.6 mm3. The antenna is designed and constructed using both CST MICROWAVE STUDIO® and CADFEKO electromagnetic solver, and in order to validate the acquired simulation results, the antenna is manufactured and tested using vector network analyzer E5071C. The measurement results show that the designed antenna attains a broadband bandwidth (S11 < −10 dB) from 2.48 to 6.7 GHz resonating at 3.6 and 5.3 GHz, respectively. The broadband bandwidth covers the two required bands: WiMAX at the frequencies 2.3/2.5/3.3/3.5/5/5.5 GHz and WLAN at the frequencies 3.6/2.4–2.5/4.9–5.9 GHz. In addition, the suggested antenna provides good gains of 2.78 dB and 5.32 dBi, omnidirectional measured radiation patterns in the E-plane and the H-plane and high efficiencies of 88.5% and 84.6% at the resonant frequencies. A close agreement of about 90% between simulation and measurement results is noticed.
Role of NLRP7 in Normal and Malignant Trophoblast Cells

Gestational choriocarcinoma (CC) is an aggressive cancer that develops upon the occurrence of abnormal pregnancies such as Hydatidiform moles (HMs) or upon non-molar pregnancies. CC cells often metastasize in multiple organs and can cause maternal death. Recent studies have established an association between recurrent HMs and mutations in the Nlrp7 gene. NLRP7 is a member of a new family of proteins that contributes to innate immune processes. Depending on its level of expression, NLRP7 can function in an inflammasome-dependent or independent pathway. To date, the role of NLRP7 in normal and in malignant human placentation remains to be elucidated. We have recently demonstrated that NLRP7 is overexpressed in CC trophoblast cells and may contribute to their acquisition of immune tolerance via the regulation of key immune tolerance-associated factors, namely HLA family, βCG and PD-L1. We have also demonstrated that NLRP7 increases trophoblast proliferation and decreases their differentiation, both in normal and tumor conditions. Actual findings suggest that NLRP7 expression may ensure a strong tolerance of the trophoblast by the maternal immune system during normal pregnancy and may directly affect the behavior and aggressiveness of malignant trophoblast cells. The proposed review summarizes recent advances in the understanding of the significance of NLRP7 overexpression in CC and discusses its multifaceted roles, including its function in an inflammasome-dependent or independent pathways.
An Ensemble Based Computational Social System for Fake News Detection in MANET Messaging

Mobile Adhoc Networks (MANETs) are utilised in a variety of mission critical situations and as such it is important to detect any fake news that exists in such networks. This research combines the power of Veracity, a unique, computational social system with that of Legitimacy, a dedicated ensemble learning technique, to detect Fake News in MANET Messaging. Veracity uses five algorithms namely, VerifyNews, CompareText, PredictCred, CredScore and EyeTruth for the capture, computation and analysis of the credibility and content data features using computational social intelligence. To validate Veracity, a dataset of publisher credibility-based and message content-based features is generated to predict fake news. To analyse the data features, Legitimacy, a unique ensemble learning prediction model is used. Four analytical methodologies are used to analyse these experimental results. The analysis of the results reports a good performance of the Veracity architecture combined with the Legitimacy model for the task of fake news detection in MANET Messaging.
The Influence of Occupational Identity on Emotional Experience

How does occupational identity shape emotional experience? Prior work has largely framed occupation and emotion either in terms of how differences in occupational status structure the experience of powerful, negative emotions or how cultural norms enforce types of acceptable emotional expression in workplaces. Complementing this work by using an identity-centered approach, this paper asks how being in one occupational identity versus another influences the emotions one is likely to experience in everyday life. I argue that one’s occupational identity generates daily interaction sets with typical others, which create opportunities for identity maintenance and confirmation. Affect Control Theory predicts that when individuals confirm identities within an interaction, they will experience the characteristic emotion of the identity. Using data from the General Social Survey’s 1996 emotions module, I find support for the hypothesis that individuals will report experiencing emotions that are closer in cultural meaning to the characteristic emotion of their occupational identity more often than emotions that are more different in cultural meaning. I additionally explore how this relationship depends on the social location of the individual. I find that this relationship is stronger for men, those with higher income, and more educational credentials.
Properties of Lime-Cement Concrete Containing Various Amounts of Waste Tire Powder under Different Ground Moisture Conditions

Lime-cement concrete (LCC) is a non-structural concrete in which lime and cement are used as the main binders. However, although LCC has many applications in reducing the settlement of foundations and providing a support layer for shallow foundations, little research has been conducted to evaluate its behaviour in various moisture conditions. Previous researchers have studied the feasibility of using waste tires in conventional concrete to alleviate their negative environmental impacts. However, in field projects, rubber has not been widely used because its application leads to the strength reduction of concrete. In the case of LCC, attaining high strengths is not required and thus application of waste tire particles sounds reasonable. This research evaluated the impact of various rubber powder contents on the fresh, geotechnical and durability properties of LCC at different saturation degrees induced by the capillary action and groundwater level increment, which has not been studied before. The results of more than 320 tests showed that the application of tire powder increases workability and decreases the water absorption of LCC. Moreover, all 60-day cured specimens exposed to 100% saturation degree experienced a strength reduction of less than 10% by using rubber powder contents varying from 0 to 20%. Moreover, increasing the saturation degree from 0 to 100% decreased the average compressive strength by 13.5 and 22% for 60-day cured samples of two different mix designs. The results of this research confirm that LCC containing up to 10% rubber powder could be promisingly used underneath or close to the groundwater table without its strength and geotechnical properties being jeopardized due to rubber employment and/or exposure to ground moisture.
14C plateau tuning – A misleading approach or trendsetting tool for marine paleoclimate studies?

Abstract. On the basis of minor time scale adjustments including the synchronization on IntCal20 the Suigetsu-based atmospheric 14C plateau structures are shown to be authentic. Their global significance is demonstrated by the coherence with the tree ring record 10 to 15 cal. ka and by coherent features in the 14C record of Hulu Cave back to 35 cal. ka. The suite of atmospheric structures can be recognized in high-resolution ocean sediment records independent of various processes leading to partial distortion of a sediment record. This provides a unique tool for global stratigraphic correlation and paleoceanographic studies as shown by supplementary figures and tables from 19 cores obtained from key locations in the world ocean.
Crowdsourcing-Based Indoor Localization With Knowledge-Aided Fingerprint Transfer

Precise indoor localization is a key requirement for the fifth-generation (5G) and beyond wireless communication systems with applications. To that end, many high accuracy signal fingerprint-based localization algorithms have been proposed. Most of these algorithms, however, face the problem of performance degradation in indoor environments, when the propagation environment changes with time. In order to address this issue, the crowdsourcing approach has been recently adopted, where the fingerprint database is frequently updated via user reporting. These crowdsourcing techniques still require precise indoor floor plans and fail to provide satisfactory accuracy. In this paper, we propose a low-complexity self-calibrating indoor crowdsourcing localization system that combines historical fingerprints with frequently updated fingerprints for high precision user positioning. We present a multi-kernel transfer learning approach that exploits the inner relationship between the historical and updated channel state information (CSI). Our indoor laboratory experimental results using Nexus 5 smartphones at 2.4GHz with 20MHz bandwidth have shown the feasibility of the proposed approach to achieve about one-meter level accuracy with a reasonable fingerprint update overhead.
Sustainable Entrepreneurship for Business Opportunity Recognition: Analysis of an Awareness Questionnaire among Organisations

An important challenge for the future is focusing on sustainability in life and business. The three elements of sustainability (economic, environmental, and social), defined in 17 factors by the United Nations (UN) as the Sustainable Development Goals (SDGs), may, therefore, be the main drivers of business competitiveness and opportunity recognition. The main aim of the article is to identify the awareness level of sustainability and sustainable development goals in the context of business opportunity areas by analysing the results of a survey of organisations in six countries (Finland, Slovakia, Italy, Austria, Spain, and Turkey). A multilingual questionnaire, administered in six participating countries, was used as a collection tool to determine the organisation’s level of awareness regarding the SDGs. A research questionnaire was filled in by 238 respondents, providing a cross-cultural view of their attitudes, knowledge, and future interest in sustainability and the SDGs. The obtained results indicate differences in the approach to sustainability issues, the scope of knowledge, interest, competencies in sustainable development and SDGs, and the content of implementation of sustainability and SDGs in organisations in different sectors, regions and countries. Further statistical evaluation of the research hypotheses states the significant relationship between the two variables: sustainable strategy and the designation of a responsible employee in each organisation rs = 0.677 (α = 0.05). It is essential to eliminate the gap in the cross-cultural approach and knowledge in engaging with sustainable strategy and its implementation in current and future organisation activities in the context of sustainability and SDGs, in order to enhance opportunities for the growth of sustainability-focused entrepreneurship across different sectors and countries.
A Brief Study on Trichomonas Vaginalis

In today's modern world women face too many challenges in front of them and in an country like India. There is still old system in which women can’t work. They are kept at home and indulged in household activities and their dreams don’t matter. they are not aware of the changes in their own body due to complete negligence or illiteracy. India is still one of the most illiterate countries in the world and its economy is still very low and beyond advancement. India is a developing country and nowadays people are starting to get aware about problems of women. Now in today's society women are allowed to work and they are not kept at their household but are given an opportunity as equals. But still there are many places in India which are not aware about problems faced by women and they don’t know how to help them and we have to provide them education about their own healthy bodily practices. Women in the modern and ancient world were affected by many such diseases which causes harm not only to them but also to their young ones if untreated. In the modern culture, now a days a new trend of having multiple sexual partners have become common and therefore, due to unsafe and unprotected sex practices and poor awareness, a lot of diseases has been transmitted worldwide to both genders. Trichomoniasis vaginalis is one of the most common sexually transmitted disease in women caused by a parasite which transmitted during unsafe and unprotected during sexual practices.

All the radiation patterns over the UHF band show bi-directional for E-plane and omni-directional at H-plane. The maximum gain obtained is 1.88 dBi.
Lightweight Security Transmission in Wireless Sensor Networks through Information Hiding and Data Flipping

Eavesdroppers can easily intercept the data transmitted in a wireless sensor network (WSN) because of the network’s open properties and constrained resources. Therefore, it is important to ensure data confidentiality in WSN with highly efficient security mechanisms. We proposed a lightweight security transmission method based on information hiding and random data flipping to ensure that the ally fusion center (AFC) can achieve confidential data transmission over insecure open links. First, the sensors’ local measurements are coded into a customized binary string, and then before data transmission, some parts of the string are flipped by the sensors according to the outputs of a pre-deployed pseudo-random function. The AFC can recover the flipped binaries using the same function and extract the measurement hidden in the string, while the enemy fusion center (EFC) cannot distinguish flipped and non-flipped data at all, and they cannot restore the measurement correctly as long as one bit in the string is not correctly recovered. We proved the security and anti-interference of the scheme through both simulations and physical experiments. Furthermore, the proposed method is more efficient such that it consumes less power than traditional digital encryptions through real power consumption tests.
Soft Assets Consideration in Smart and Resilient City Development

For a smart city, soft or non-physical assets share an important capital component with many impacts in different contexts. They enable a city to deliver and mainstream a people-centered policy in addition to the benefits provided by traditional, hard infrastructure. Soft assets can involve social and human capital, knowledge, participation, and innovative approaches that drive value in the city. However, it is always a challenge for city policy makers to identify and strengthen these soft assets using a systemic approach due to their inherent characteristics. This paper argues that soft assets should be strategically integrated into the development process of smart and resilient cities. Therefore, exploring various approaches to prioritize soft asset consideration would provide helpful guidelines to city policy makers for municipal value creation, and identify where the greatest needs for soft or intangible assets lie. This paper examines how to identify and decide which soft assets should take priority in smart and resilient cities. The findings can assist policy makers in their consideration of an optimal mix and balance of soft assets required in the city to improve living structures for a people-centered approach.
Evaluation of Neuropathic Pain Component in Myofascial Pain Syndrome; Its Effect on Emosyonel State, Sleep and Quality of Life

Objective: The aim of this study was to evaluate the neuropathic pain component in patients with myofascial pain syndrome, and to examine the effects of neuropathic pain on emotional status, sleep and quality of life. Material and Methods: 73 patients with MPS in their neck or upper back region admitted to the tertiary university hospital were included. Questionnaires were administrated to the patients via face-to-face interviews, and included sociodemographic variables. The patients were evaluated for neuropathic component by DN4 questionnaires, and pain by visual analog scale (VAS). Validated questionnaires measuring emosyonel status, sleep quality and quality of life were used. Results: Of the 73 patients, 48 (65.8%) were female and 25 (34.2%) were male. The mean age of all recruited patients was 38.2±10.6 years. According to the DN4 scale 56.2% of the patients had neuropathic pain. MPS patients were divided into two groups as those with and without neuropathic pain. VAS, BDI, and PSQI scores were significantly higher among MPS patients with neuropathic pain than among MPS patients without neuropathic pain (p<0.01). The patients with neuropathic pain had lower scores for all the parameters of the SF-36. Morever vitality, social function, mental health, and emotional role dimensions scores were significantly lower in MPS patients with neuropathic pain than MPS patients without neuropathic pain (p<0.01). Conclusion: An appropriate diagnosis and treatment of the neuropathic pain plays an important role and can reduce the pain, improve the quality of life and sleep qulity, and decrease the level of depression in treatment of MPS.
L.A.V.O.E.: An Easy Mnemonic for the Initial Management of Sepsis in Obstetric Patients

Maternal Sepsis remains as one of the most common causes of morbidity and mortality between obstetric patients with the 11% of maternal deaths worldwide. It also contributes, to the increased risk of other common causes of maternal death such as hypertensive disorders, hemorrhage, and thromboembolism. Despite of the recent advances in preventative strategies, diagnostic tools, antimicrobial therapy and laboratory tests, morbidity and mortality in pregnant population continued to increase over the years
Generational and Ideological Gaps in Democratic Support: Seeds of Deconsolidation in Post-Crisis Southern Europe?

ABSTRACT This article explores trends in overall levels of democratic support in Portugal, Spain, Italy, and Greece. Additionally, the article examines the extent to which the experience of the steep economic downturn in Southern Europe had specific effects on democratic support across different generations and ideological groups by examining survey data that span three decades. The evidence is mixed concerning the resilience of democratic values in the four South European countries, ranging from stability in Portugal to noticeable decline in Italy. Members of the ‘millennial’ generation appear to be more susceptible to the period effect of the crisis, whereas left-wing and centrist citizens are more likely to select democracy as the best form of government compared to right-wing citizens.
Curcumin and vinblastine induce apoptosis and impair migration in human cutaneous melanoma cells

Cancer is an important cause of lethality, and melanoma is associated with less than 10% of survival. The traditional treatment includes the use of vinblastine, and it is associated with side effects. Curcumin is extracted from Curcuma longa rhizomes, and studied in many diseases, producing a variety of effects. We investigated the role of various cellular pathways concerning apoptosis, cell cycle enzymes in melanoma cell line SK-MEL-28, after treatment with curcumin, vinblastine, or a combination of both, for 24 hours. After this, we performed cell cycle, apoptosis, wound healing assay, comet assay on cells, and evaluated nitrite accumulation (nitric oxide (NO•) byproduct). Curcumin increased cells in apoptosis and reduced the number of cells in the G1 phase. Vinblastine increased the production of nitrite, and cells in early apoptosis, mainly through the inducement of DNA damage. Cell migration was impaired in all tested groups. In conclusion, curcumin impaired migration, producing NO•, and promoting apoptosis of tumoral cells. Vinblastine also impaired cell migration and increased levels of NO•. Curcumin might be included as an adjuvant in the treatment of melanoma, and help treatment of melanoma, and further studies are needed, especially regarding the synergistic effect of curcumin and vinblastine in the treatment.
Sustainability Reporting and Corporate Reputation: The Moderating Effect of CEO Opportunistic Behavior

The present study’s main objective is to assess the impact of non-financial sustainability reporting (NFSR) on corporate reputation and the role of the CEO in the opportunistic behavior of companies listed on the Tehran Stock Exchange. In total, 178 firms were assessed for this paper during 2013–2020. In this study for calculating the NFSR, environmental sustainability reporting (ESR), social sustainability reporting (SSR), governance sustainability reporting (GSR) and ethical sustainability reporting (ETSR), Arianpoor and Salehi’s comprehensive and conceptual model has been used. In addition, the literature states that a CEO’s power can be classified as an opportunity for discretion and opportunistic behavior in CEOs that is in contrast with stakeholder demands. To this end, in this study, CEOs’ power has been used as an indicator for the CEO’s opportunistic behavior, and the CEO pay slice (CPS) index was used to calculate the CEO’s level of power. The results revealed that NFSR affects corporate reputation positively. In addition, ESR, SSR, ETSR and GSR positively affect corporate reputation. Moreover, the CEO’s power affects the relationship between NFSR/ESR/SSR/ETSR and corporate reputation. Because managers desire to engage in social and ethical activities, they try to hide the company’s errors and increase its reputation. The results revealed that the CEO’s power did not affect the relationship between GSR and corporate reputation. Since companies in the Tehran Stock Exchange are under intensive supervision, such as in governance, the impact of a CEO’s power and the interaction of a CEO’s power and GSR on company reputation in this study might, thus, not apply to these companies. It is crucial to investigate NFSR, corporate reputation and CEO power within Iran-specific conditions because of differences in emerging markets and developing countries such as Iran, which have diverse ownership structures, economic status, legal systems, government policies, and culture.
