Authors: Gonzales-Gemio Carla , Cruz-Cázares Claudio , Parmentier Mary Jane
Published: December 2020

Responsible innovation has always been an important issue in discourses addressing the major challenges faced by humankind in terms of natural resource degradation, climate change, economic progress and societal well-being. However, its integration into industry is still in its infancy, and even more so when it comes to small and medium-sized enterprises (SMEs). The aim of this research is to use a systematic literature review to develop a conceptual model for responsible innovation and its relationship with SME performance, in connection with sustainable innovation and corporate social responsibility practices. A bibliometric analysis of 102 articles collected between 2000 and April 2020 from the Web of Science database was used, in addition to the systematic literature review using the Gephi and NVivo software. The study presents an overview of the articles, authors, and most influential journals and research clusters identified, and provides a solid conceptual framework to be applied in this field and in the context of SMEs.

Published: December 2020

Rapid urbanization has led to the continuous deterioration of the surrounding natural ecosystem. It is important to identify the key urbanization factors that affect ecosystem services and analyze the potential effects of these factors on the ecosystem. We selected the Beijing, Tianjin, and Hebei (BTH) urban agglomeration to investigate these effects, and designed three indicators to map the urbanization level: Population density, gross domestic product (GDP) density, and the construction land proportion. Four indicators were chosen to quantify ecosystem services: Food production, carbon sequestration and oxygen production, water conservation, and soil conservation. To handle the nonlinear interactions, we used a random forest (RF) method to assess the effect of urbanization on ecosystem services in the BTH area from 2000 to 2014. Our study demonstrated that population density and economic growth were the internal driving forces affecting ecosystem services. We observed changing trends in the effect of urbanization: The effect of population density on ecosystem services increased, the effect of the proportion of construction land was consistent with population density, and the effect of GDP density on ecosystem services decreased. Our results suggest that controlling the population and GDP would significantly influence the sustainable development in large urban areas.
The Strength Characterisation of Concrete Made with Alumina Waste Filler
Authors: Oti Jonathan , Kinuthia John , Adeleke Blessing
Published: December 2020

This study covers an in-depth investigation into the properties and practicality of the utilization of up to 40% Alumina Waste Filler (AWF) as a partial Portland Cement (PC) replacement material. AWF is a by-product from the recycling of aluminium, produced when salt slag is smelted and cleaned. Its use in concrete will lessen the landfill requirements for AWF disposal, and reduce the strain of the growing requirements and cost of PC. The results obtained from this study showed that the addition of AWF to the concrete mix caused a reduction in the compressive and tensile splitting strength values, and a less-workable concrete was achieved for every increase in the quantity of AWF added to each mix. The addition of AWF influenced the hydration reaction process and reduced the cumulative production of the heat of hydration over time, whilst the permeability of the concrete decreased.
Sustainability of Vibration Mitigation Methods Using Meta-Materials/Structures along Railway Corridors Exposed to Adverse Weather Conditions
Authors: Kaewunruen Sakdirat , Qin Zhangjun
Published: December 2020

Noises and vibrations caused by operating transport systems can seriously affect people’s health and environmental ecosystems. Railway-induced vibrations in urban settings can cause disturbances and damages to surrounding buildings, infrastructures and residents. Over many decades, a number of mitigation methods have been proposed to attenuate vibrations at the source, in the transmission path, or at the receiver. In fact, low-frequency or ground-borne vibration is turned out to be more difficult to be mitigated at source, whilst some attenuation measures in propagation path can be applicable. To broaden the mitigating range at the low-frequency band, the applications of meta-materials/structures have been established. In railway systems, periodic structures or resonators can be installed near the protected buildings to isolate the vibrations. Despite a large number of proposed attenuation methods, the sustainability of those methods has not been determined. Based on rational engineering assumptions, the discounted cash flows in construction and maintenance processes are analysed in this study to evaluate lifecycle costs and the quantity of materials and fuels, as well as the amount of carbon emissions. This study is the world’s first to identify the efficacy and sustainability of some transmission path attenuation methods in both normal and adverse weather conditions. It reveals that geofoam trenches and wave impeding blocks are the most suitable methods. Although metamaterial applications can significantly mitigate a wider range of lower frequency vibrations, the total cost and carbon emissions are relatively high. It is necessary to significantly modify design parameters in order to enable low-cost and low-carbon meta-materials/structures in reality.

Authors: Boateng Kofi Konadu , Obeng George Yaw , Mensah Ebenezer
Published: December 2020

Data on greenhouse gas emission levels associated with fertilization applied in smallholder paddy rice farms in Ghana are scanty. The current study investigated fertilization types to determine their eco-friendliness on yield, Global Warming Potential (GWP) and Greenhouse Gas Intensity (GHGI) in a major rice season in the forest zone of Ghana. In total, five treatments were studied viz Farmer Practice (BAU); Biochar + Farmer Practice (BAU + BIO); Poultry Manure + Farmer Practice (BAU + M); Biochar + Poultry Manure + Farmer Practice (BAU + BIO + M); and Control (CT). Fluxes of methane (CH4) and nitrous oxide (N2O) were measured using a static chamber-gas chromatography method. N2O emissions at the end of the growing season were significantly different across treatments. BAU + BIO + M had highest N2O flux mean of 0.38 kgNha−1day−1 (±0.18). BAU + M had the second highest N2O flux of 0.27 kgNha−1day−1 (±0.08), but was not significantly different from BAU at p > 0.05. BAU+BIO recorded 0.20 kgNha−1day−1 (±0.12), lower and significantly different from BAU, BAU + M and BAU + BIO + M. CH4 emissions across treatments were not significantly different. However, highest CH4 flux was recorded in BAU+BIO at 4.76 kgCH4ha−1day−1 (±4.87). GWP based on seasonal cumulative GHG emissions among treatments ranged from 5099.16 (±6878.43) to 20894.58 (±19645.04) for CH4 and 756.28 (±763.44) to 27201.54 (±9223.51) kgCO2eqha−1Season−1 for N2O. The treatment with significantly higher yield and low emissions was BAU + M with a GHGI of 4.38 (±1.90) kgCO2eqkg−1.

Published: December 2020

The current global situation regarding climate change makes it necessary to promote the circular economy and the use of more environmentally friendly technologies in the construction sector. To that end, it is of interest to deepen our understanding of the performance of half-warm mix asphalt (HWMA) manufactured with high proportions of reclaimed asphalt pavement (RAP). Thus, in the present study, a laboratory analysis was carried out in which the behavior of HWMA manufactured with 100% RAP and without rejuvenators was compared with that of a control mix, i.e., an HWMA manufactured with 0% RAP. In particular, we analyzed the compaction energy with a gyratory compactor, mixing time and temperature, volumetric properties, moisture damage resistance through indirect tensile tests after immersion (ITS), stiffness based on the resilient modulus, resistance to permanent deformation using wheel tracking tests, and fatigue resistance through indirect tensile fatigue tests (ITFT). Both mixtures displayed adequate volumetric and mechanical properties, but the performance of the high-RAP HWMA was better than that of the control mixture in terms of resistance to permanent deformation in hot areas. In addition, the high-RAP HWMA without rejuvenators could provide energy and material savings, thus promoting sustainable development.
A Statistical Framework for Assessing Environmental Performance of Quality Wine Production
Authors: Dede Despoina , Didaskalou Eleni , Bersimis Sotirios , Georgakellos Dimitrios
Published: December 2020

The present work presents a statistical framework for analysing and evaluating the environmental performance of 21 wines (protected designation of origin or protected geographical indication) produced in Greece, through their complete lifecycle. For this purpose, the life cycle assessment methodology was used. It is well known that lifecycle thinking is a scientific approach that can support businesses in decision making towards sustainable consumption and production. However, such techniques provide a large amount of multi-dimensional data that are difficult to comprehend and interpret. Therefore, the application of an appropriate statistical framework to aid this assessment, which should be as unambiguous and reliable as possible, is needed. This statistical framework should be based on the lifecycle inventory results, on an appropriate multivariate technique such as principal component analysis, and on probability distributions, thereby providing an objective framework to assist the evaluation of the environmental performance of the products. Applying the proposed framework to 21 Greek wines, we found that the proposed framework could be used for categorizing the examined wines according to their environmental impact severity, as well as the impact types associated with them.
Novel and Diverse Non-Rabies Rhabdoviruses Identified in Bats with Human Exposure, South Dakota, USA
Authors: Hause Ben M. , Nelson Eric , Christopher-Hennings Jane
Published: December 2020

Bats are a host and reservoir for a large number of viruses, many of which are zoonotic. In North America, the big brown bat (Eptesicus fuscus) is widely distributed and common. Big brown bats are a known reservoir for rabies virus, which, combined with their propensity to roost in human structures, necessitates testing for rabies virus following human exposure. The current pandemic caused by severe acute respiratory syndrome coronavirus 2, likely of bat origin, illustrates the need for continued surveillance of wildlife and bats for potentially emerging zoonotic viruses. Viral metagenomic sequencing was performed on 39 big brown bats and one hoary bat submitted for rabies testing due to human exposure in South Dakota. A new genotype of American bat vesiculovirus was identified in seven of 17 (41%) heart and lung homogenates at high levels in addition to two of 23 viscera pools. A second rhabdovirus, Sodak rhabdovirus 1 (SDRV1), was identified in four of 23 (17%) viscera pools. Phylogenetic analysis placed SDRV1 in the genus Alphanemrhavirus, which includes two recognized species that were identified in nematodes. Finally, a highly divergent rhabdovirus, Sodak rhabdovirus 2 (SDRV2), was identified in two of 23 (8.7%) big brown bats. Phylogenetic analysis placed SDRV2 as ancestral to the dimarhabdovirus supergroup and Lyssavirus. Intracranial inoculation of mouse pups with rhabdovirus-positive tissue homogenates failed to elicit clinical disease. Further research is needed to determine the zoonotic potential of these non-rabies rhabdoviruses.

Due to planning of the Moon and deep space exploration programs, the crew sanitary hygiene support with a closed loop of hygiene water assumes great importance. Currently, Russia and the USA are investigating the hygiene water recovery process using reverse osmosis as the most energy efficient method. In the meantime, the urine water processor (SRV-U-RS) based on vacuum distillation method with thermal energy recovery has been developed in Russia and is being tested aboard the ISS. The processor energy consumption is comparable with the energy consumption in hygiene water recovery through reverse osmosis. Therefore, research and testing of a prototype integrated urine water and hygiene water processor as applied to the space station conditions have been arranged and conducted. The investigations demonstrated the recoverability of the hygiene water, including its mixture with urine by vacuum distillation in science hardware SRV-U-RS-type system. The results obtained ensure development of an integrated urine water and hygiene water processing system.

This research aims to explore the main meaning that became the core values of empowerment that done by Credit Union (CU). Through a case study approach on CUMK, the researcher then explores the values of CU in stages based on an economic perspective, a church perspective (ecclesia), and a biblical perspective. We found that the meaning of CU empowerment is very comprehensive and holistic that unite inclusive economic concept and the social teaching of the church and also the word of God on bible that focused on raise human dignity to live prosperous. Thus, we conclude that core values of CU empowerment is compassion. Personal human well-being as well as community welfare, should be developed, because man is the creator, center and destination of all social economic life. Whoever obeys to Christ, and first of all looking for Kingdom of God, will draw from Him compassion that stronger and clearer to help all brothers and sisters, and to be soulful of compassion carry out the opus of justice (Gaudium et Spes, 3: 63 and 72).

Published: December 2020

The aim of this study was to determine the effects of zinc (Zn), iron (Fe), nickel (Ni), copper (Cu), and cobalt (Co) in different concentrations on the total consumption amount, pupal weight, pupal protein and lipid content, the development time of the last instar Hyphantria cunea. For this purpose, ten diets were prepared using 4% and 12% concentrations of each metal. A total of 11 diets were made, including one control diet. Chloroform was used to determine the pupal lipid amounts. Protein analysis was performed by semi-micro Kjeldahl method with Kjeltec Auto 1030 analyzer (Tecator, Sweden). ANOVA-Dunnet test was used for statistical analysis. With increasing iron and copper concentrations in the diet, the consumption amounts, pupal weights, pupal protein and pupal lipid amounts of the larvae decreased, while the development time was prolonged. Consumption amounts, pupal weights, pupal protein and pupal lipid amounts of the groups containing nickel and cobalt were found to be higher than the control group. It was determined that with increasing zinc concentration, consumption amounts, pupal weights, and pupal protein amounts of the larvae increased, but pupal lipid amounts decreased. In this study, it has been shown that heavy metals affect the physiological processes of H. cunea larvae.
Introduction to the Entrepreneurship Special Issue
Authors: Bylund Per
Published: December 2020

Austrian economics is the only school of economic thought that is well represented in the study of entrepreneurship. Austrian theories, concepts, and perspectives on entrepreneurship make up an important part of what is modern entrepreneurship theory. Yet while entrepreneurship scholars often take inspiration or even borrow from Austrian economics, the reverse is scarcely true. Even so, there is reason to believe both sides would benefit from more interaction and collaboration. The aim of this special issue is to facilitate a synergistic discussion between Austrian economists with an interest in entrepreneurship theory and entrepreneurship scholars with an interest in the Austrian approach.
Carl Menger's Grundsätze as a Foundation for Contemporary Entrepreneurship Research
Authors: Westgren Randall
Published: December 2020

This paper takes the subjective value theory, conception of economic goods, and the hierarchy of needs from Carl Menger's Grundsätze der Volkswirtschaftslehre (1871) to elaborate a model of strategic entrepreneurship. Menger's account of subjective valuation by buyers of goods in market exchange fills a gap in most conceptual approaches to entrepreneurship, which are based on a highly impermeable boundary around the entrepreneurial firm. We examine how this account "closes" an economic model of entry for an entrepreneurial firm in an existing rivalry network by making the assessment of value explicit with respect to buyer needs relative to goods sold by incumbent firms. A formal representation of Menger's needs hierarchy in the face of qualitatively different market goods is the centerpiece of the strategic entrepreneurship model. This conceptual model is tied to methods of eliciting subjective valuations of product attributes and buyer needs fulfilment from the literatures of consumer behavior, marketing, and organizational psychology. This serves as a methodological basis for scholarship in entrepreneurship.
Finding the Entrepreneur-Promoter: A Praxeological Inquiry
Authors: Bylund Per
Published: December 2020

Entrepreneur-promoters, or the pioneers of economic improvement, provide an essential market function which economics cannot do without. Yet Ludwig von Mises maintains that this function lies beyond what can be defined with praxeological rigor. This paper attempts to find a praxeological subcategory of entrepreneurship that conforms with Mises’s indeterminate references to the entrepreneur-promoter in Human Action. Rather than relying on the evenly rotating economy, which is commonly used for analyzing entrepreneurship, the imaginary construction of a specialization deadlock is employed, adapted from Per Bylund’s Problem of Production. This construction allows for the derivation of a praxeological subcategory of entrepreneurship, distinct from the general function of uncertainty bearing, which suggests a theoretical explanation for what constitutes the driving force of the market process.
Why (a Theory of) Opportunity Matters: Refining the Austrian View of Entrepreneurial Discovery
Authors: Dempster Gregory
Published: December 2020

The concept of entrepreneurial opportunity has undergone a period of useful critique and refinement since Venkataraman (1997) and Shane and Venkataraman (2000) employed the term as one of the defining features of entrepreneurship studies. This paper presents a novel Austrian reinterpretation of this concept as an intersubjective phenomenon that emerges from the dual entrepreneurial process of discovery and judgment. Just as markets can be described as price discovery procedures for existing goods, services, and resources, entrepreneurship can be usefully described as a price discovery procedure for future goods, services, and resources. This view retains the essential elements of Kirzner’s (1973) approach while also refining the opportunity discovery concept within an evolutionary realist framework for understanding entrepreneurial motivation and action.
Entrepreneurial Empowerment: You Are Only as Good as Your Employees
Authors: Ng Desmond
Published: December 2020

As employees are increasingly recognized as an important source of ideas and inspiration, contemporary leadership research finds that the central task of leaders is to empower employees to realize their skills and talents to achieve an organizations' visions and goals. Drawing on this leadership premise, this study develops the concept of entrepreneurial empowerment (EE). EE has structural and psychological dimensions that empower employees to utilize their knowledge to solve the internal Hayekian knowledge problem. EE introduces an endogenous discovery process in which entrepreneurial leaders play a central role in empowering employees to use their localized knowledge. This entrepreneurial discovery process offers opportunities to adapt and innovate using the knowledge experiences of employees. This study underscores that a venture’s success is not tied to an entrepreneur’s inspirational ideas (or, more broadly, their asymmetric knowledge experiences), but to their ability to inspire ideas from all levels of their business hierarchy.

Published: December 2020

We propose a method to realize a ratchet-type skyrmion-based racetrack memory with a loop structure using current and validate the proposed method using micromagnetic simulations. The proposed method utilizes the ratchet effect composed of a gradient with perpendicular magnetic anisotropy (PMA). The skyrmion moves circularly inside a track, which is composed of regions with various gradients of PMA. The results demonstrate that the recording density and operating frequency of the memory are approximately 40 Gbit inch–2 and 42 MHz, respectively, when the diameter of the skyrmion is 28.1 nm.

The goal of this paper is to provide a critical overview of Moroccan insurance/pension fund investments in alternative assets through data analysis techniques. The results show that the risk of reserve depletion and the investment restrictions imposed by the regulator are not the real reasons why insurance companies / pension funds in our database reduce their investments in the alternative asset market. The results also show that the barriers that deter Moroccan insurance/pension funds from alternative assets are of two kinds: the first are of a general nature and concern the whole world (not just Morocco), the second type of barriers are specific to the Moroccan context.

Background: The surgical treatment of inguinal hernias has evolved through several stage, history of groin hernia is the history of surgery itself. But, chronic pain is still a major irritating post-operative complain of the patient. The objective of the present study was to compare post-operative outcomes of mesh fixation with monofilament non-absorbable v/s monofilament absorbable suture material in terms of postoperative pain, chronic groin pain, seroma formation, wound infection and recurrence in Lichtenstein hernioplasty. Methods: This is a single centre, prospective randomized controlled study of 152 cases of inguinal hernia comparing post-operative outcomes of mesh fixation with monofilament non-absorbable v/s monofilament absorbable suture material in Lichtenstein hernioplasty at Baroda Medical College and S.S.G. Hospital, between 1st December 2017 to 30th November 2018. Results: Total 152 patients of unilateral or bilateral inguinal hernia were studied 76 in each group. Chronic groin pain mean visual analogue scale score at 3 months was higher in group with non-absorbable suture compared to monofilament absorbable group (1.3±0.9 v/s 0.95±0.8 p value <0.05). Conclusions: Monofilament absorbable suture is associated with less chronic groin pain and compared to monofilament non-absorbable sutures.

Gingival Fibromatosis is the overgrowth of the gingiva characterized by an expansion and accumulation of the connective tissue with the rarely presence of an increased number of cells. It is hereditary or is induced as a side effect of systemic drugs. As an inherited disorder, Gingival Fibromatosis may be part of a genetic syndrome or it may be isolated, in which case it is referred to as hereditary gingival fibromatosis. Some of the cases of Hereditary Gingival Fibromatosis associated with dental abnormalities like Amelogenesis Imperfecta. It is a general term for a number of conditions that affect enamel formation and/or calcification. The purpose of this article is to report manifesting syndrome characterized by Gingival Fibromatosis associated with dental abnormalities, including generalized thin hypoplastic Amelogenesis Imperfecta, intrapulpal calcifications, delay of tooth eruption, pericoronal radiolucencies in unerupted teeth, dental agenesis and root dilacerations.

DETERMINATION OF PROGNOSIS OF SNAKE BITE CASES BY NEUTROPHIL-LYMPHOCYTE RATIO AND PLATELET-LYMPHOCYTE RATIO.
Authors: Allichandi Ravi , Kurahatti Manjunath
Published: December 2020

Objectives:
Neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) have recently gained popularity as simple, inexpensive, and highly accurate inflammatory markers and they have been suggested as useful predictors for clinical prognosis in critically ill patients in various medical conditions. Snakebites can result in serious complications. Our country is a snakebite-endemic area. The parameters for the prognosis of snakebites are very valuable due to the inadequacy of acute inpatient services, as well as the excessively intense traffic at emergency rooms (ERs); therefore, we aimed to detect the importance of the neutrophil–lymphocyte ratio (NLR) and the platelet–lymphocyte ratio (PLR) as parameters in the prognosis for snakebites.
Methods: In this study, patients who presented at the ER within 24 hours after a snakebite were retrospectively analyzed. The sex, age, exposure duration, body part affected, hospitalization period, complications, mortality rate, and blood parameters of ER patients were assessed.
Results: 51 healthy individuals who were suitable in terms of sex and age were included in the control group. It was detected that the average NLR (p=0.001) and PLR (p=0.005) values were statistically significantly higher in the patient group than in the control group. On comparing the patients discharged from the ER with those who remained hospitalized, the NLR (p= 0.002) and PLR (p= 0.006) values were significantly higher in the patients who remained hospitalized . The NLR (p=0.004) and the PLR (p=0.003) values in the patients who developed complications were significantly higher than those in patients who did not develop complications.
Conclusion:
High levels of on admission NLR and PLR were associated with worse clinical profile and poorer outcome. The hospitalization period, complication developments, and poor prognosis in snakebites may be predicted using the NLR and PLR values, which are easily available and inexpensive blood parameters.
GLYCEMIC CONTROL MODIFIES THE ASSOCIATION BETWEEN MICROALBUMINURIA AND C-REACTIVE PROTEIN IN TYPE 2 DIABETES MELLITUS
Authors: Jivani Krishkumar A.
Published: December 2020

BACKGROUND: HbA1c is most commonly used parameter for glycemic control in type 2 diabetes mellitus patient.
AIM
The aim of the study was to evaluate whether any association exists between C-reactive protein and microalbuminuria in well controlled and poorly controlled Type 2 DM patients.
METHOD :
In this study, we included total 90 patients of type 2 Diabetes Mellitus admitted in GKGH , Bhuj during the period from Aug. 2018 to June 2019.
The subjects were divided into two groups according to glycemic control as Group 1(Poorly controlled Diabetics) and Group 2( Well controlled Diabetics )
The groups 1 and 2 (based on Glycemic control) were further divided into 3 subgroups A, B and C (based on CRP level) with 15 subjects in each of these six subgroups.
RESULT:
Subjects with poor glycemic control had elevated values of MAU at all comparative levels of CRP. Further, it was shown that the level of MAU increased considerably with increasing level of CRP.
CONCLUSION :
There is a significant positive correlation between the level of MAU and CRP status in poorly controlled Type 2 diabetics.

Published: December 2020

AIM: To study the effect of adjuvant melatonin with clomiphene citrate on ovulution and fertility rates in infertile PCO patients.
MATERIAL AND METHODS: A total of 107 cases participated in the study out of which 7 women were excluded from the study. So the results of 100 women were analyzed. Out of 100 women 50 were of group A i.e. clomiphene supplemented with melatonin group and 50 were in group B which was clomiphene only group with no supplementation. Cases were followed for three cycles and pregnancy rates in both groups were evaluated.
RESULTS: Study demonstrated the potential benefit of melatonin supplementation in naturally conceived cycles where ovulation induction was given by en-clomiphene citrate. The ovulation rates were comparable in both study Vs control group (68% Vs 66%) while there was increase in pregnancy rate in melatonin group (36% Vs 24%). However difference between pregnancy rates in both the groups failed to reach statistically significant levels (p value 0.4065).
CONCLUSION: The adjuvant role of melatonin with en-clomiphene citrate in cases of Infertile PCO patients is in improving pregnancy rates; which is due to strong anti-oxidant effect of melatonin which in turn reduces oxidative stress thus resulting in good quality oocyte production.

Combining Alamouti Scheme with Block Diagonalization Beamforming precoding for 5G Technology over Rician Channel
Authors: Ciflikli Cebrail
Published: December 2020

Wireless communication faces a number of adversities and obstacles as a result of fading and co-channel interference (CCI). Diversity with beamformer techniques may be used to mitigate degradation in the system performance. Alamouti space-time-block-code (STBC) is a strong scheme focused on accomplishing spatial diversity at the transmitter, which needs a straightforward linear processing in the receiver. Also, high bit-error-rate (BER) performance can be achieved by using the multiple-input multiple-output (MIMO) system with beamforming technology. This approach is particularly useful for CCI suppression. Exploiting the channel state information (CSI) at the transmitter can improve the STBC through the use of a beamforming precoding. In this paper, we propose the combination between Alamouti STBC and block diagonalization (BD) for downlink multi-user MIMO system. Also, this paper evaluates the system performance improvement of the extended Alamouti scheme, with the implementation of BD precoding over a Rayleigh and Rician channel. Simulation results show that the combined system has performance better than the performance of beamforming system. Also, it shows that the combined system performance of extended Alamouti outperforms the combined system performance without extended Alamouti. Furthermore, numerical results confirm that the Rician channel can significantly improve the combined system performance.
