Certain fractional calculus and integral transform results of incomplete 
 ℵ ‐functions with applications

In this paper, we study certain interesting and useful properties of incomplete ℵ ‐functions. The incomplete ℵ ‐function is an extension of the ℵ ‐function. We find several useful classical integral transforms of these functions. Further, we examine the fractional calculus with the incomplete ℵ ‐functions and point out several special cases. Finally, we give the applications of incomplete ℵ ‐functions in detecting glucose supply in human blood.
Business intelligence and analytics value creation in Industry 4.0: a multiple case study in manufacturing medium enterprises

Abstract Medium enterprises (MEs) form a majority of enterprises in several regions, yet they are underrepresented in the literature. The digital transformation known as Industry 4.0 (I4.0) brings new data streams into enterprises. MEs and large enterprises will both leverage business intelligence and analytics (BI&A) to improve their business performance, so the study of the conditions favouring value creation of BI&A is of interest. However, there are few studies focusing on the impact of business intelligence and analytics (BI&A) on value creation in I4.0 and none focusing on MEs. Using a multiple case-study design, this paper explores factors linked to BI&A business value creation in manufacturing MEs that are undergoing an I4.0 transformation. Findings suggest enterprises resources and capabilities are not sufficient to predict business value: organizational learning and organizational culture have a non-negligible influence for MEs.
Development of a Daily GRACE Mascon Solution for Terrestrial Water Storage

The Gravity Recovery and Climate Experiment (GRACE) and GRACE‐Follow On missions have provided a global history of terrestrial water storage changes since 2002. Traditional GRACE products resolve monthly time‐variable gravity at spatial resolutions of 300–500 km, with many recent efforts focusing on regularized mass concentration (mascon) solutions to better resolve signals spatially. However, monthly resolution inhibits the applicability of GRACE to investigations of sub‐monthly signals. This study presents a new daily mass change solution estimated as deviations from the NASA Goddard Space Flight Center (GSFC) converged monthly mascon product and quantifies the fundamental trade‐off between temporal and spatial resolution in GRACE‐only solutions. As an iteration of the GSFC product, this daily solution represents a mixing of monthly information at higher relative spatial resolution with daily information at lower relative spatial resolution, resolving each temporal scale at the best resolution achievable without requiring hydrological model dependencies in the estimation. The resolution of the daily mascons is 300–400 km at high latitudes and 600–1,000 km lower, depending on each daily orbital track and the proximity of each mascon to constraint region boundaries (e.g., coastlines). Through simulations and model comparisons, we demonstrate that daily signals over areas larger than 400,000 km 2 are recoverable, with basins larger than 800,000 km 2 exhibiting strong signal recovery relative to leakage. This analysis establishes baselines for daily signal recovery from GRACE in the context of longer time scale solutions, characterizes leakage inherent in daily GRACE information, and creates new opportunities for applying GRACE to investigations of sub‐monthly signals.
An Integrated Semi-Double Stage-Based Multilevel Inverter With Voltage Boosting Scheme for Photovoltaic Systems

This article proposes a single-phase, seven-level, transformerless inverter, employing a semi-double stage-based conversion technique, which is particularly suitable for photovoltaic (PV) applications. The proposed configuration achieves voltage boosting using a non-isolated interleaved buck-boost converter, which is fused with the inverter configuration through two switched capacitors (SCs). The interleaved front-end boost stage is capable of achieving a voltage gain of three while resulting in reduced peak current stress on the switching devices. In this topology, a part of the load power is transferred directly from the PV source, while the other part is transferred through the SCs. The proposed topology and the associated pulsewidth modulation (PWM) technique are capable of reducing the leakage current by isolating the terminals of the PV source in the freewheeling state. This article also presents a thorough analysis of the stray capacitor voltage and the common-mode voltage (CMV). These analyses reveal that the high-switching frequency transitions are eliminated in both of these waveforms. Furthermore, the proposed topology results in the reduction of low-frequency transitions in the stray capacitor voltage and the CMV, which in turn result in further reduction of the leakage current. The simulation and experimental results are in agreement with the mathematical analysis of the proposed inverter.
Environmental and Health Impacts of the Change in NMHCs Caused by the Usage of Clean Alternative Fuels for Vehicles

ABSTRACT Vehicle exhaust and roadside air samples were collected at Guangzhou, Shenzhen and Chengdu in China, where liquefied petroleum gas (LPG), liquefied natural gas (LNG) and compressed natural gas (CNG)—common fuel alternatives for vehicles worldwide—are used, respectively. The emission characteristics, ozone formation potential (OFP) and health risks of nonmethane hydrocarbons (NMHCs) in conventional and clean alternative fuel exhaust emitted by vehicles were assessed to explore the environmental and health effects from the change in NMHCs due to using clean alternative fuels. Our results indicate that the fuel type significantly impacted the composition of the roadside air. The OFP values for the total NMHCs were much lower in the CNG (2.5 ppmv), LNG (4.7 ppmv) and diesel (4.5 ppmv) exhaust than in the gasoline (94.3 ppmv) and LPG (23.1 ppmv) exhaust, indicating that using CNG and LNG may effectively reduce O3 formation due to vehicle exhaust. Additionally, the hazard quotient (HQ), hazard index (HI) and cancer risk (Risk) of NMHC species in the vehicle exhaust were calculated. Both the HI and Risk of these species in the exhaust from gasoline-powered vehicles greatly exceeded those from the other four types of vehicles, suggesting that using clean alternative fuels instead of gasoline benefits human health.
An Explorative Study of Creative Idea Generation Using Mobile Collaboration Platform

This study examines creative idea generation within a given task involving the use of a mobile collaboration platform (MCP). Drawing upon the theoretical perspectives on cognitive creativity, mobility, and self-select communication mode, the study proposes a research model that explains how individuals generate creative ideas through MCP use in a group collaboration context. To validate our model, survey data was collected from individuals involved in a group collaboration—particularly when performing tasks that requiring creative solutions. The results of this study indicate that: 1) MCP use has a positive effect on the individual’s creative idea generation; 2) both perceived MCP effectiveness and perceived freedom determine the individual’s MCP use levels; and 3) the individual’s personal innovativeness level in information technology (PIIT) has a conditional effect on the relationship between the perceived MCP freedom and MCP use. The significance of these findings stems from the fact that creative idea generation through group collaboration is a highly sought-after quality in organizational setting. Given the centrality of the mobile ecosystem in today’s organizational task environment, this study presents both theoretical and practical contributions. during

Prospective Study of the Effectiveness of Intramedullary Fixation of Unstable Peritrochanteric Fractures with Interlocking Proximal Femoral Nail

Background: Femur is the longest and strongest bone in the body and one of the principal load bearing in the lower extremity. Fracture of this bone may result in prolonged morbidity and extensive disability unless the treatment is appropriate. Among fractures of femur, Trochanteric fractures are associated with substantial morbidity and mortality. Aim of this study to assess the effectiveness of Intramedullary fixation of unstable peritrochanteric fractures with interlocking proximal femoral nail. Methods: It is a prospective study involving 21cases.All the cases enrolled in this study were from the Department of Orthopaedics, kanyakumari Govt medical college. Boyd and Griffin classification and Harris hip scoring is used. Results: Among 21 cases, 20 patients came for regular followup. Out of 20 cases 14 were males 6 were females. After the follow up period of 10.75 months it was observed that 1 case developed superior cut out of lag screw with severe varus deformity and another two cases developed varus deformity which is less than 10% and another 3 cases developed abductor lurch. All the other patients were back to their pre injury occupation. Conclusion: PFN proved as a better implant with adequate surgical technique. The requirement and followup based changes in design of PFN decrease the complication rates and increases all the postulated advantages of Intramedullary devices used in the treatment of trochanteric fractutres. Introduction Fractures around the trochanter region of femur are one of the commonest fracturesencountered in orthopaedics and also the most devastating injuries of the elderly. The incidence of this fracture increase with advancing age. In younger patients the fractures usually result from high energytrauma like RTA and fall from height and accounts for only ten percent . older patients suffering from a minor fall can sustain fracture in this area because of weakened bone due toosteoporosis or pathological fracture and this accounts for 90%. Until 1960's non operative treatment was the option available for these type of fractures in the form of traction with prolonged bed rest with fracture healing occurring in tento twelve weeks (usually) followed by a lengthy programme of www.jmscr. igmpublication.org Impact Factor 5.84 Index Copernicus Value: 83.27 ISSN (e)-2347-176x ISSN (p) 2455-0450 DOI: https://dx.doi. org/10.18535/jmscr/v5i4.93
Distinct actin-dependent nanoscale assemblies underlie the dynamic and hierarchical organization of E-cadherin

Intercellular adhesion mediated by E-cadherin is pivotal in maintaining epithelial tissue integrity and for tissue morphogenesis. Adhesion requires homophilic interactions between extracellular domains of E-cadherin molecules from neighboring cells. The interaction of its cytoplasmic domains with the cortical acto-myosin network, appears to strengthen adhesion, although, it is unclear how cortical actin affects the organization and function of E-cadherin dynamically. Here we use the ectopic expression of Drosophila E-cadherin (E-cad) in larval hemocytes, which lack endogenous E-cad, to recapitulate functional cell-cell junctions in a convenient model system. We used fluorescence emission anisotropy-based microscopy and Fluorescence Correlation Spectroscopy (FCS) to probe the nanoscale organization of E-cad. We find that E-cad at cell-cell junctions in hemocytes exhibits a clustered trans-paired organization, similar to that reported for the adherens junction in the developing embryonic epithelial tissue. Further, we find that extra-junctional E-cad is also organized as relatively immobile nanoclusters as well as diffusive and more loosely packed oligomers and monomers. These oligomers are promoted by cis-interactions of the ectodomain and, strikingly, their growth is constantly counteracted by cortical actomyosin. Oligomers in turn assist in generating nanoclusters that are stabilized by cortical acto-myosin. Thus, actin remodels oligomers and stabilizes nanoclusters, revealing a requirement for actin in the dynamic organization of E-cad at the nanoscale. This dynamic organization is also present at cell-cell contacts (junction), and its disruption affects junctional integrity in the hemocyte system, as well as in the embryo. Our observations uncover a hierarchical mechanism for the nanoscale organization of E-cad, which is necessary for dynamic adhesion and maintaining junctional integrity in the face of extensive remodeling.
FROM OPENNESS TO RESTRICTION: SOUTH AMERICAN GOVERNMENTS’ RESPONSES TO THE VENEZUELAN EXODUS, 2014-2019

The Venezuelan exodus represents one of the most extensive political and humanitarian crises ever experienced in South America. Yet, governments in the region have failed to promote stability in Venezuela and have been unable to implement a coordinated response to the migration crisis across the subcontinent. By focusing on foreign and domestic action, I aim to better understand, beyond diplomatic discourse, what South American governments have done to deal with the spillovers of the Venezuelan collapse, and which factors have influenced their decision-making process. The present study offers a concept that identifies key attributes that constitute a facilitated immigration policy to Venezuelans. It is a pivotal step to provide tools for empirical analysis of the phenomenon. Then, I investigate which factors have influenced governments’ political response to the Venezuelan immigration crisis. Why president Evo Morales, Caracas’s close ally, did not facilitate immigration from Venezuela? Why the Brazilian president, Michel Temer, in turn, implemented an open-door policy for Venezuelan immigrants? This MSc thesis applies Qualitative Comparative Analysis (QCA) to the sample of nineteen South American governments from 2014 to 2019 — the epicenter of the Venezuelan exodus. Through QCA, I identify conditions shared by cases that have reached the same outcome — openness or restriction to Venezuelan immigration. Rightwing ideology has placed many South American presidents in strong opposition to the Maduro government. Thus, facilitating the arrival of Venezuelans immigrants on humanitarian grounds would instead send a powerful political message condemning the Bolivarian regime.
From needs to deeds

This paper aims to study a change process on a university campus from a pedagogical perspective. The aim of the process, as expressed by facilities management and faculty leadership, was to create campus learning landscapes that promote social encounters and learning between students and researchers, as well as other embedded groups. The paper addresses how pedagogical needs are or should be integrated in the design process. ,The data of this case study regarding change on campus consist of semi-structured interviews of information-rich key stakeholders identified using snowball sampling method. The interviews were analysed to find common themes and reference to pedagogical needs and expectations. ,Campus usability and reliability are improved when pedagogy informs the design, and needs such as sense of belonging (human) and connectivity (digital) are fulfilled. User-centred design should be followed through during the whole campus change process, and there should be sufficient communications between user groups. ,The discussion is based on one case. However, the recommendations are solid and also reflected in other related research literature regarding campus change initiatives. ,The paper states recommendations for including pedagogical needs in campus learning landscape change and underlines the role of real user-centred processes in reaching this goal. ,The study introduces the concept of campus reliability and highlights a missing link from many campus change cases – pedagogy – which is suggested to be essential in informing campus designs that produce usable and reliable future-ready outcomes.
Immediate effect of taping in physical performance of osteoarthritis of knee joint

Background: Osteoarthritis (OA) is a degenerative joint disease which is an arthritic condition in which the articular cartilage has begun to erode and become soft and frayed. Current treatment is aimed at reducing symptoms and improving functions. Taping of the patella to pull it medially, followed by exercises, has been recently recommended for the treatment of knee OA. Aims and Objectives: This study aims to study the effect of taping in improving physical performance of OA of knee joint. Materials and Methods: The research project was conducted after getting clearance from Human Research Ethics Committee of the H M Patel Institution for Education and Research center. In this randomized control trial study, 50 subjects were included from the Outpatient Department of the Physiotherapy, Shree Krishna Hospital. Participants were divided into two groups; there were 25 participants in each group. One group received only exercise and the other group received tapping along with exercise. Outcomes were measured by Western Ontario and McMaster Universities OA Index (WOMAC) and timed up and go test (TUG). Results: Data are analyzed by finding P value. And also by correlating between prevalues and postvalues of outcomes measured. There was statistically significant improvement in WOMAC (P < 0.001) as well as TUG (P = 0.058), in the group which includes both taping and exercises. There was statistically significant improvement in WOMAC (P < 0.002) in the group which included only exercises, whereas there was no statistically significant improvement in TUG (P = 0.123). Conclusion: Taping is effective to improve the functional outcome of the patients with the OA of knee joint.
INVESTIGATION OF OPTIMAL CARBON TAX RATE IN IRAN USING AN INTEGRATED CLIMATE-ECONOMY MODEL

This study used an integrated climate-economy model for dynamic optimization of the carbon tax rate in Iran, which can serve as a key policy tool for controlling climate change through the internalization of social costs of carbon emissions. For this purpose, the optimal carbon tax rate in Iran for 18 five-year periods from 2011 to 2101 was estimated using the data pertaining to the 2011-2016 period based on three approaches: social cost of carbon, temperature changes, and emission changes. The results showed that using the first approach, the optimal carbon tax rate for the Iranian economy would be 50 Rials/tonne in the beginning and 350 Rials/tonne in the later periods. Using the second and third approaches, this rate would be 15% at the beginning of the period and reach as high as 38% under the worst emission conditions.
Improved Model-Based Phase-Shift Control for Fast Dynamic Response of Dual-Active-Bridge DC/DC Converters

Fast dynamic response of the output voltage is an essential requirement for dual-active-bridge (DAB) dc/dc converters under the operation of the voltage source. This article proposes an improved model-based phase-shift control (MPSC) strategy that combines model-based control with the design of feedback regulators and load current feedforward (LCFF) regulators. The improved MPSC strategy can ensure that the DAB has high-bandwidth control performance over the entire transmission power range without changing the controller parameters online. The design of controller parameters is simple and has the same model parameter as sensitive as MPSC. Its utility and effectiveness are verified by simulations and experiments.
Multipoint Observations of Magnetosheath Response to Foreshock Transients

Multispacecraft observations of the magnetosheath responses to various foreshock transients in a single event on 17 March 2004 are reported in this paper. The Cluster spacecraft recorded long‐standing large amplitude ULF waves with both compressive and transverse components in the magnetosheath. Additionally, two transient structures with depressions in density and magnetic field were observed in this period. One structure contains greatly heated and significantly deflected plasmas in the middle and a cold solar wind population at its trailing edge, which is identified as a spontaneous hot flow anomaly with a remnant of the foreshock caviton. It is transmitted through the magneosheath and evolved into a magnetosheath cavity. This cavity was subsequently encountered by the Double Star TC‐1 spacecraft deeper inside the magnetosheath. Meantime, fluxes of hot ions in the energy range of 5–38 keV exhibit quasiperiodic variations. These energetic ions are earthward with pitch angle distributions of alternately field aligned or antifield aligned. A correlation between its flux variations and the transverse fluctuations of the ULF waves is found. Moreover, magnetosheath filamentary structures with a series of anticorrelated oscillations of density and temperature were observed simultaneously.
CRISPR-Cas12a exploits R-loop asymmetry to form double-strand breaks

Most type V CRISPR-Cas interference proteins use a single RuvC active site to make RNA-guided breaks in double-stranded DNA substrates, an activity essential for both bacterial immunity and genome editing applications. The best-studied of these enzymes, Cas12a, initiates DNA cutting by forming a 20-nucleotide R-loop in which the guide RNA displaces one of the DNA strands of a double-helical substrate, positioning the DNase active site for first-strand cleavage. However, crystal structures and biochemical data have not explained how the second strand is cut to complete the double-strand break. Here, we show that Cas12a-mediated R-loop formation destabilizes DNA at the second-strand cleavage site, which is located outside of the R-loop structure and beyond the 3′ end of the guide RNA. Chemical and fluorescent DNA probes reveal that this destabilization is an intrinsic feature of DNA flanking the RNA-3′ side of R-loops and does not require direct protein interactions. Interestingly, DNA flanking the RNA-5′ side of R-loops is not intrinsically unstable. This asymmetry in R-loop structure may explain the uniformity of guide RNA architecture and the single-active-site cleavage mechanism that are fundamental features of all type V CRISPR-Cas systems.
The impact of market orientation on the internationalisation of SMEs

Purpose A key point in the internationalisation process of companies comes with the choice of international market. Following this choice, the results companies may thereby obtain help in measuring their level of international performance. This study aims to measure the impact of internationalisation processes in keeping with company market orientations (MOs) through measuring their effect on international performance. Design/methodology/approach The authors obtained the data from a questionnaire sent out by email to a total of 8,103 exporting companies and/or with interests in exporting (the study population) registered in the AICEP-Portugal Global database that provided the email addresses of the company representatives responsible for internationalisation. The authors received a total of 320 valid responses (sample). Findings The results display a positive MO effect both on internationalisation processes and on international performance. The authors also note the importance of studying the influence of strategic orientations on internationalization processes, motivated by the particular SME’s characteristics. Originality/value The authors aim to contribute to the study of the influence of the MO, both upstream and downstream, thus seeking to verify its impact on internationalization processes.
