A Prospective Study of Early Postoperative Outcome of D2 Gastrectomy: A Tertiary Hospital of Bangladesh

Introduction: Gastrectomy with proper lymphadenectomy is considered the cornerstone of treatment for potentially curable gastric cancer. Stomach cancer is one of the important leading causes of cancer related death in worldwide. Annually, it was diagnosed with 9, 89,600 new cases and 7, 38,000 deaths (10% of all cancer death) in worldwide. The overall prognosis is not very favorable. However, surgery in the form of gastrectomy is the only treatment modality for a chance of long term survival as well as hope for cure. Aim of the study: Aim of the study was to find outcome of Early Postoperative Outcome of D2 Gastrectomy. Material & Methods: This prospective study was conducted at the Department of Surgical Oncology, National Institute of Cancer Research & Hospital (NICRH), Dhaka, Bangladesh from January 2019 to December 2020. A total 80 number of gastric cancer patients who were underwent gastrectomy were considered in this study. Statistical Analysis was performed with help of Epi Info (TM) 7.2.2. 2. EPI INFO is a trademark of the Centers for Disease Control and Prevention (CDC). Descriptive statistical analysis was performed to calculate the means with corresponding standard deviations. Results: The mean age (mean ± SD) of the patients was 49.10±8.32 years with range 28-66 years and the median age was 48.5 years. The age group 45-54 years (50.0%) were significantly higher than other age group (Z= 3.26; p<0.001). Only 5.0% were with age between 25-34 years and 27.5% of the patients were with age ≥55 years. Thus in this study the patients with age between were in higher risk of having gastric cancer. Proportion of males (75.0%) was significantly higher than that of females (25.0%) (Z=7.07; p<0.0001). Conclusion: Surgery for gastric cancer is the only hope for cure or long term survival in the arena of multimodal management of cancers. It provides quick symptom relief by loco regional control, adds to survival of the individual, cure in case of early gastric cancer and proper staging for planning of subsequent adjuvant treatment.

Differences between end user innovators and embedded user innovators in diffusion channel selection: the moderating role of technological advances

PurposeIn heterogeneously segmented markets, collaborating with product users in product innovation is important for business success. End user innovators and embedded user innovators differ in terms of their prior embeddedness in the target industry. The purpose of this study is twofold. First, the authors empirically compare these two types of user innovators in terms of their diffusion channel selection. Second, the authors analyze how the technological advances of their innovations affect this difference.Design/methodology/approachUsing an online questionnaire survey, this study collected a sample of 237 user-generated innovations in Japan and analyzed several hypotheses using quantitative statistical approaches.FindingsThe analysis shows that embedded user innovators are more likely than end user innovators to transfer their innovations to producers rather than peers. As the technological advances of their innovations increase, end user innovators' likelihood of transferring their innovation to producers increases more significantly than that of embedded user innovators.Originality/valueThis is the first paper to investigate the difference between end user innovators and embedded user innovators with respect to their diffusion channel selection as well as the moderating role of technological advances. The findings bring new perspectives to the domains of user–producer collaboration and technology transfer.
Performance Evaluation of Coupling Variants for an Active Middle Ear Implant Actuator: Output, Conductive Losses, and Stability of Coupling With Ambient Pressure Changes

Introduction: This study aims to investigate the performance of an active middle ear implant actuator for various coupling configurations. Actuator output and conductive losses were measured, and the stability of coupling was evaluated by challenging the link between actuator and ossicles through pressure events in magnitudes that occur in daily life. Methods: Actuator coupling efficiency and the occurrence of conductive losses were measured in 10 temporal bones through laser Doppler vibrometry on the stapes footplate for various coupling types (incus short process with and without laser hole, incus long process, stapes head). To test the stability of coupling, actuator output was measured before and after daily-life pressure events that were simulated; Valsalva maneuvers (500 cycles of −40 to +60 hPa) and jumping into a swimming pool and diving 3 m deep (a step change of 300 hPa). Results: Actuator output was similarly high for all types of coupling to the incus (short process and long process) and most efficient for coupling to the stapes head. Conductive losses occurred in two temporal bones (TBs) for short process coupling but for seven TBs for coupling to the incus long process. All coupling types were stable and did not lose efficiency after pressure events in the low-frequency range (<1 kHz). Losses in output of 13 to 24 dB were observed in one TB at frequencies from 3 to 6 kHz. Conclusion: Actuator output was similarly high for all types of coupling to the incus but coupling to the incus long process led to a higher occurrence of conductive losses. All three coupling configurations connected the actuator securely to the ossicular chain, under variations of barometric pressure that can be expected in daily life.
Different determinants affecting first mover advantage and late mover advantage in a smartphone market: a comparative analysis of Apple iPhone and Samsung Galaxy

ABSTRACT Entry timing is critical for a firm’s sustainability, and it is determined after comparing the first mover advantage (FMA) and the late mover advantage (LMA). This study aims to continue the extant discussion on FMA and LMA to explore the important determinants and their effects on FMA or LMA in a smartphone market. The methodology of building a theory from a comparative case study is adopted using Apple iPhone and Samsung Galaxy cases in a smartphone market. This study verified that market- and firm-level determinants are more linked with FMA, and the isolating mechanism along with the environment as well as firm-level enablers are useful for explaining FMA. This study also uniquely found that the product-level determinant is closely linked with LMA, which has not been explored much in relation to LMA. This study theoretically contributed to extending the conceptual framework as well as enabling the mechanism of entry advantage, and it has managerial implications of how the first mover or the late mover can benefit from their entry advantage by exploiting their relative strength.
The Influence of Power and Trust on the Initiation and Duration of Modal Shift Solutions

Modal shift to more energy-efficient alternatives, such as from road to rail or sea, is one path to reduce negative environmental effects. Transport providers and shippers have crucial roles in modal choice decisions, and a better understanding of the influence of interorganisational factors on modal shift is needed. The purpose is to increase the understanding of opportunities for modal shifts by exploring the influence of power and trust at the interface between transport providers and shippers. Aspects of power (coercive, reward, legitimate, expert and referent) and trust (contractual, competence and goodwill) influencing modal shifts were identified from interviews with shippers and transport providers in Sweden. During the initiation phase of modal shift, power appears more important, while trust is shown essential for the duration. By proactively suggesting modal shift, transport providers can use expert power to create rewards and referent power, through recognition of their expertise. Building trust, particularly goodwill trust, such as time invested in understanding the other party, transparency about challenges and jointly seeking solutions, is key to establish long-term modal shifts. This paper contributes to modal shift literature with insights on power balances and trust between transport providers and shippers.
Enhancing topic clustering for Arabic security news based on k-means and topic modelling

The internet has become one of the main sources of news spread as it unleashed the information dissemination space, where the news websites express opinions on entities while also reporting on recent or unusual security risks. Recently, many research studies have focused on sentimental reflection on the views and impressions of people utilising natural language processing and analytical linguistics. Therefore, we have collected corpus from popular Arabic websites that publish articles related to recent security issues, and we provide light weight preprocessing techniques where data is term matrix is transformed. We also present an intensive lexical ‐ driven data analysis with visualised data views, as our topic modelling technique can effectively extract significant topics from all the collected text from different websites. Our experiments validate the k ‐ means clustering algorithm with and without the latent Dirichlet allocation topic modelling method, and we adopted various validation techniques to measure the topic clustering internally and externally. As shown in the experiments' results, our proposed combined method has a high round index rate of 87.2%, with a large number of topics and clusters.
Historical Developments of Pyrolysis Reactors: A Review

This paper provides a review of pyrolysis technologies, focusing on reactor designs and companies commercializing these technologies. The renewed interest in pyrolysis is driven by the potential to convert lignocellulosic materials into bio-oil and biochar and the use of these intermediates for the production of biofuels, biochemicals, and engineered biochars for environmental services. This review presents slow, intermediate, fast, and microwave pyrolysis as complementary technologies that share some commonalities in their designs. While slow pyrolysis technologies (traditional carbonization kilns) use wood trunks to produce char chunks for cooking, fast pyrolysis systems process small particles to maximize bio-oil yield. The realization of the environmental issues associated with the use of carbonization technologies and the technical difficulties of operating fast pyrolysis reactors using sand as the heating medium and large volumes of carrier gas, as well as the problems with refining the resulting hi.
Crystal structure of monoclinic hafnia and comparison with monoclinic zirconia Locality: synthetic

The crystal structure of monoclinic HfO2 was determined using Weissenberg techniques. Data were obtained from a needlelike single crystal which was grown from a lithium molybdate melt. The crystal was rotated about the α axis, and reflection data were obtained for nine levels. A three-dimensional least-squares refinement confirms that monoclinic hafnia is isomorphous with monoclinic zirconia. The atomic coordinates in the structures agree within one standard deviation. Thus, the fractional coordinates for the metal atom differ by less than 0.0005 and those for the oxygen atoms by no more than 0.01. Whereas three of the seven Hf–O distances are larger than the corresponding Zr–O distances, the average value is approximately 0.01 A smaller. The average metal-metal distance is approximately 0.02 A less in HfO2 than in ZrO2.
A review of high ideality factor in gallium nitride-based light-emitting diode

Theory concerning the high ideality factor of gallium nitride (GaN) based light- emitting diode (LED) has been reviewed. The presence of a high ideality factor indicates a large forward voltage that results in efficiency reduction. The paper suggests that tunneling is the main reason defining the exponential behaviour of current-voltage measurements, which leads to a high ideality factor. However, there is also a paper that suggests that the design of current geometry in the LED chip defines the value of ideality factor. An effective current spreading geometry in the LED chip will minimize the ideality factor and make it fall between the ideal range of 1 to 2. Besides, how the ideality factor is calculated will also play a major role in defining its value. By calculating the ideality factor based solely on the radiative recombination current formula, the value of ideality factor can result in an ideal ideality factor of 1.08.
Perceived mate competition risk influences the female mate choice and increases the reproductive effort in the annual killifish Millerichthys robustus

Female life-history strategies can be sensitive to social context, responding adaptively to current or future mate limitations by reproductive competition conditions. Competitive environments provide the conditions for adjusting reproductive decisions in order to compensate for the negative impacts of competition between individuals, thus maintaining reproductive fitness. This research aimed to test the effect of perceived competition risks for mate choice and their consequences in the reproductive effort of females of the annual killifish Millerichthys robustus induced throughout an audience effect. First, I evaluated the female mate choice using a classic dichotomous preference study based on male size, showing that the females do not show a significant preference for males of any size in a scenario without perceived competition; however, females turn selective under competition risk, choosing the large males. I then evaluated the reproductive effort of females through embryo production without an audience for 10 days, and next with an audience of females for two periods of 10 days. Results showed that females produced significantly more embryos when they perceived a risk of competition. Also, females turn selective under risk of competition, probably due to an increased parental investment expressed by the reduction of the female-male encounters and breeding rate, the increased reproductive effort and the time spent searching a mate. Females that mate with larger males may gain access to more benefits derived from his social status, as best territories and high-quality sites for the spawn, thus increasing the probabilities of survival for the females and their offspring. I propose that, as a life-history strategy to preserve individual fitness, the direction of the sexual selection is modified by the perceived competition risk, and that competition is not necessarily related with the high-cost investments; in fact, it may also have, beneficial effects for the individual female reproductive success.
Comparison of Physicochemical and Sensory Characteristics of Soybean Sprouts from Different Cultivars

Physicochemical and sensory characteristics of soybean sprouts from domestic and foreign soybean cultivars were investigated. 100-seed weights of domestic cultivars were much larger than that of Canadian cultivar and recommended cultivars were larger than traditional cultivars. Water absorption of soybeans increased sharply to initial 6 hrs during steeping, and did not change much thereafter. In all soybean cultivars 16 amino acids were detected and the contents of Asp, Glu, Lys and Arg were more than 50% of total amino acid contents. All soybean cultivars showed some difference in composition of fatty acids and the content of linoleic acid was highest. The contents of K and P were high and those of Fe and Zn were low. The compression force of hypocotyl after cultivation was the highest in Eunha and the lowest in Junjeori and the compression force of cotyledon was the highest in Danyeop and the lowest in Canadian cultivar. Qualitative discription analysis for cooked soybean sprouts and soups showed significant difference in 6 characteristics of yellowness of cotyledon, size of cotyledon and so on.
Socially Responsible HR in Action: Learning from Corporations Listed on the Dow Jones Sustainability Index World 2018/2019

As ethical management, corporate social responsibility (CSR), and corporate sustainability (CS) are increasingly permeating business discourse, contemplating the role of human resources (HR) in helping organizations with socially responsible management is a proactive acceptance of stakeholders’ expectations while reinforcing the field’s identity and contribution. In response, the we examined the HR policies and practices of 46 multinational enterprises (MNEs) listed on the Dow Jones Sustainability Index (DJSI) World 2018/2019 to add new insights to the literature and inform the HR field on how to move forward with socially responsible HR. Content analysis and inductive conceptualization of the MNEs’ HR activities produced a triangular pyramid for socially responsible HR, constructed with eight major themes at the individual, organizational, and institutional levels. Building on the findings, we suggest implications for practice and research, and conclude with urging the HR community to demonstrate leadership in setting the agendas and facilitating change toward socially responsible management.
ON GRAEV’S THEOREM FOR FREE PRODUCTS OF HAUSDORFF TOPOLOGICAL GROUPS

Abstract The paper gives a simple proof of Graev’s theorem (asserting that the free product of Hausdorff topological groups is Hausdorff) for a particular case which includes the countable case of $k_\omega $ -groups and the countable case of Lindelöf P-groups. For this it is shown that in these particular cases the topology of the free product of Hausdorff topological groups coincides with the $X_0$ -topology in the Mal’cev sense, where X is the disjoint union of the topological groups identifying their units.
Optimization of accurate resist kernels through convolutional neural network

Accurate and fast lithography model is necessary for computational lithography applications such as optical proximity correction (OPC) and lithography rule check. In lithography model, optical model calculates image intensity followed by resist model that outputs a resist contour. Resist model is an empirical model, in which images are convolved with resist kernels and their weighted sum is used to derive a resist model signal that is compared with some threshold. Conventional resist model use a simple form of resist kernels such as Gaussian kernels, therefore it requires many kernels to achieve high accuracy. We propose to use free-form resist kernels. Resist model has the same structure as convolutional neural network (CNN), thus, we represent resist model with free-form kernels in CNN and train the network. To avoid overfitting of the proposed model, we initialize the model with conventional Gaussian kernels. Training data is carefully selected so that resist contour is accurately predicted. A conventional resist model with 9 Gaussian kernels is converted into a model with 2 free-form kernels, which achieves 35% faster lithography simulation. In addition, simulation accuracy in CD is improved by 15%.
Towards Digital Sustainability: Profiles of Millennial Reviewers, Reputation Scores and Intrinsic Motivation Matter

Profiles of millennial reviewers and gamification can contribute to digital sustainability as a driver of innovation and growth. The study aims to detect if there are profiles of reviewers that can be grouped together, in order to apply a specific gamification to them and to make it sustainable over time. In this way, more information will be generated through the reviews that will help responsible consumers to choose better in their purchase decisions. The objective of this study is twofold. First, it aims to characterize online product reviewers based on their intrinsic motivations and self-perception when they comment, identifying their main motivations. Second, it aims to classify these individuals based on the acceptance of gamification elements while commenting on and relating them to the intrinsic attributes that determine their behaviors. A survey method design was used to capture responses from 187 millennial reviewers of Amazon in Spain. The relationships between motivations and the types of reviewer were extracted from the accommodation of the dataset using decision trees (DTs), specifically, the J48 algorithm. To contribute to the second objective, this paper elaborates a typology of reviewer analysis based on cluster analysis and DTs. It is confirmed that online product reviewers can be characterized based on their intrinsic motivations, which are mainly egoistic motives, competence and social relatedness. The obtained results show that the J48 DT provides excellent classification accuracy of approximately 95% in identifying reviewers based on intrinsic motivations. Similarly, egoistic intrinsic motives are decisive in focusing gamification strategies.
