How you treat your patients today, affects them tomorrow: Sinus tachycardia-induced cardiomyopathy

Background: Tachycardia-induced cardiomyopathy (TCM) is a reversible form of myocardial dysfunction because of tachyarrhythmias. Therefore, it is essential to identify arrhythmias in patients presenting with myocardial dysfunction without apparent aetiology. Case: Herein, we present a thirty-seven-year-old male with bouts of prolonged sinus tachycardia and severe mental stress, averaging >130 beats per minute, before abdominal operations more than once in a few months. A notably dynamic ventricular stunning was noted that partially normalized in a few days, once relieving relieving tension and reduced heart rate. Complete normalization of ventricular function was observed after five months of maintaining the average heart rate. Initially, the present case was missed due to its paroxysmal nature. Later, the patient was cured with a maximum tolerated dose of beta-blockers, anti-failure, and small doses of anxiolytic agents. Our case is a rare case report of recurrent TCM the same patient due to episodes of marked sinus tachycardia. Conclusion: Sinus tachycardia is often considered a physiological response to mental stress that may cause cardiac injury related to a prolonged stress response. Treatment of stress sinus tachycardia-induced cardiomyopathy (sinus tachycardia-ICM) leads to recovery of myocardial function. The literature does not recommend controlling heart rates in patients with persistent sinus tachycardia preoperatively, but it is a therapeutic option for preparing patients for operation. Successfully, beta-blockers were used in our patient and should be considered in similar case scenarios.
Is inflation caused by deteriorating inflation expectations or excessive monetary growth?

The near-universal practice of inflation targeting has strengthened the belief of central banks that all that is needed to control inflation is to anchor expectations with a credible inflation target. The use of Taylor rule augmented DSGE models for policy analysis and forecasting adds credence to the view that, provided inflation expectations remain stable, actual inflation will be driven by expectations. The ultimate drivers of inflation are subsidiary to the central bank operation of act-ing on inflation expectations for the control of inflation. This article poses the question whether inflation is caused by deteriorating inflation expectations or excessive monetary growth. It takes as its theoretical inspiration Friedman's theory of nominal income determination. We use quarterly data of one-year-ahead inflation expectations produced by the Bank of England, and medium-run inflation expectations backed out of five-year bond yields as measures of long-term inflation expectations. To this we add actual inflation, nominal GDP, and M4 to define a four-variable VAR. The results reveal that M4 Granger causes inflation and inflation expectations, and a variance decomposition of inflation shows that while inflation expectations help to drive inflation, after a period of between five and eight quarters money supply dominates the variance decomposition.

Nanoconfined Bulk-Gas Transport Behavior over a Wide Range of Knudsen Number

Shale matrix, located at Guizhou Province, is rich in nanopores, and gas slippage takes place during shale gas development, resulting in inapplicability of the classical Navier-Stokes equation. Investigation of gas transmission mechanism in nanoscale is helpful to reach a clear understanding of shale gas production performance. On the basis of the Knudsen number, the gas ﬂ ow mechanism is divided into continuous ﬂ ow, slippage ﬂ ow, transition ﬂ ow, and Knudsen di ﬀ usion. Notably, the accurate characterization of transition ﬂ ow is still challenging up to date. Although there are many established models, they either fail to cover all the ﬂ ow mechanisms or contain many ﬁ tting parameters, the determination of which requires a large number of experimental and molecular simulation data, limiting application of the existing models. Therefore, establishment of bulk-gas transport model over a wide range of Knudsen number without ﬁ tting parameters is urgent. First of all, existed theoretical models are compared, and the advantages and disadvantages of previous contributions are analyzed. Weight factors of Knudsen di ﬀ usion and slippage ﬂ ow are obtained, respectively, according to Knudsen ’ s model and Wu ’ s model. Then, a model, free of empirical coe ﬃ cients, is proposed. After that, e ﬀ ects of pore size, reservoir pressure, and temperature on transmission capacity are investigated. As the proposed model does not contain ﬁ tting parameters and remains high accuracy over a wide range of Knudsen number, it shares broad application potential, like shale gas production prediction, reserve estimation in Guizhou Province.
Occurrence of Marek’s disease in flocks in the Journal of Veterinary Medicine and Research Central Occurrence of Marek’s disease in household chicken flocks in the Mekong delta

Marek’s disease (MD) is a common lymphomatous and neuropathic disease of chicken caused by alphaherpesvirus, it has been caused significant economic losses to the chicken production as a result of the mortality and morbidity. The aim of the study was to determine the occurrence of Marek’s disease virus infections in chicken household farms in the Mekong delta of Vietnam, and to analyze clinical cases occurring in the years 2018–2019. This study was carried out from August 2018 to September 2019, during this time, 16 MD suspicious chicken flocks were observed, and 40 chickens were subjected to anatomopathological examination, and PCR testing for confirmation of MD and MDV (Marek’s disease virus) serotyping. All of examination flocks (16/16) were confirmed being involved with MD, nearly all cases were in acute form, with typical lesions of visceral lymphomas in internal organs, especially in the liver. Besides the presence of MDV-1(Marek’s disease virus serotype1) from 100.0% of tested chicken flocks (16/16), MDV-3 (Marek’s disease virus serotype3) were also found from 7/16 (43.75%) of MD flocks. Morbidity and mortality at sampling time varied from 1.0% to 42.11%, and 0.6% to 10.0%, respectively. Chicken flocks with MD vaccination have lower morbidity and mortality. These first finding data confirm endemic MD in the Mekong delta and prove it continues to be a threat to chicken production, in general. Thus, it is essential to develop sustainable vaccine strategies, and strict biosecurity practice in order to prevent losses from this disease.
Assessment of outcome of early and delayed repair of bile duct injuries

: Aim: To compare outcome of early and delayed repair of bile duct injuries. Methodology: Sixty- four patients with bile duct injuries of either gender were divided into group I (Early repair) and group II (Delayed repair). Operative findings such as injury classification and procedural variables and postoperative course, including 30-day re-admission and 90-day mortality, were recorded. Results: Aetiology was cholecystectomy in 25 and 21, abdominal trauma in 7 and 8, and non-biliary abdominal procedures in 2 and 5 groups I and II, respectively. There were 18 males and 14 females and 16 males and 16 females in groups I and II, respectively. Hospital length of stay was 7.1 days in group I and 8.4 days, 30 days of re-admission was seen in 3 and 4, and 90 days of mortality was seen in 2 in group I and 1 in group II.

Conclusion: Early repair found to be better as compared to delayed repair of bile duct injury.
Dysregulation of Innate and Adaptive Immune Responses in Asymptomatic SARS-CoV-2 Infection with Delayed Viral Clearance

Asymptomatic infection with SARS-CoV-2 is a major concern in the control of the COVID-19 pandemic. Many questions concerning asymptomatic infection remain to be answered, for example, what are the differences in infectivity and the immune response between asymptomatic and symptomatic infections? In this study, based on a cohort established by the Wuchang District Health Bureau of Wuhan in the early stage of the COVID-19 pandemic in Wuhan in 2019, we conducted a comprehensive analysis of the clinical, virological, immunological, and epidemiological data of asymptomatic infections. The major findings of this study included: 1) the asymptomatic cohort enrolled this study exhibited low-grade but recurrent activity of viral replication; 2) despite a lack of overt clinical symptoms, asymptomatic infections exhibited ongoing innate and adaptive immune responses; 3) however, the immune response from asymptomatic infections was not activated adequately, which may lead to delayed viral clearance. Given the fragile equilibrium between viral infection and host immunity, and the delayed viral clearance in asymptomatic individuals, close viral monitoring should be scheduled, and therapeutic intervention may be needed.
Toxicological evaluation of Hb cleanser ® bitters on biochemical parameters in Wistar rats

This study was carried out to evaluate the effect of HB Cleanser bitters on biochemical parameters in male Wistar rats. Twenty-eight animals were assigned into four groups of seven animals each. Groups A, B, C received 1, 1.03 and 1.29 ml/kg of the HB bitters respectively while group D (control), received 1 ml normal saline. All administrations were done orally and daily for 28 days. The feed and fluid intake were measured daily and the body weight weekly. Phytochemical screening revealed the presence of saponins, flavonoids and cardiac glycosides. Acute toxicity results showed that the LD50 of HB Cleanser Bitters was greater than 5000 mg/kg with no mortality. There was a significant (P<0.05) increase in body weight. In addition, HB bitters caused at 1 ml/kg significant (P<0.05) increase in total bilirubin, conjugated bilirubin, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, and urea more than the other doses compared to negative control. A significant (P<0.05) decrease was observed in the levels of total protein and albumin compared to negative control. The findings from this study showed that HB cleanser Bitters may adversely affect hepatic and renal indices and therefore should be used with caution.
Association of Ferritin and Serum Iron with Insulin Resistance Indices in Gestational Diabetes

Objectives: Investigation of the association of serum iron and ferritin with insulin resistance (IR) indices in pregnant women with gestational diabetes mellitus (GDM). Methods: Serum ferritin and iron and IR indices were measured in the 50 pregnant women with GDM and 350 non-GDM, and association of IR indices with serum iron and ferritin was evaluated. Results: Ferritin in the GDM group was significantly correlated with all IR indices except HOMA-B. No significant relationship found between iron levels and IR indices, except HOMA-IR. Conclusion: Increased serum iron and ferritin levels may increase insulin resistance and the risk of developing GDM.
Computer-aided design for analog wireless fronthaul of B5G cellular communication systems

Specialties of an analog fronthaul based on Radio-over-Fiber architecture and key principles of exploiting microwave photonics technology when designing a millimeter-wave Radio Unit (RU) are reviewed and discussed. To clarify, in this paper we perform a comparative simulation for a specific example of developing an obligatory RU's node as a reference oscillator with an output radio frequency (RF) of more than 100 GHz, which is typically implemented by means of a circuit that includes a relatively low-frequency RF oscillator followed by a high-order frequency multiplier. Following the principles and approaches outlined, we propose and describe two alternative schemes for implementing a frequency multiplier from 4.25 to 102 GHz using microwave-electronics or microwave-photonics approach. Further, using Cadence AWRDE software with an additional introduction of the previously proposed models of optoelectronic devices, their main characteristics are considered. To ensure the practical orientation of the model experiments, the parameters of each of the models used are selected based on the specifications of commercially available discrete components.
DEGREE ASSORTATIVITY IN INTRAORGANIZATIONAL NETWORKS: IMPLICATIONS FOR INVENTION PERFORMANCE

: We investigate the implications of the degree assortativity of intra-firm networks for firms’ innovation performance. We argue that prevalent patterns of collaborative relationships between organizational members can lead to variations in the levels of degree assortativity in intra-firm networks, ranging from disassortative structures (highly central members connect with peripheral members) to assortative ones (highly central members connect with other highly central members and vice versa). These patterns influence knowledge access and resource mobilization pathways and are thus associated with various firm-level invention outcomes. Using coarsened exact matching methodology and controlling for other characteristics of the intra-firm network structures, we find that assortative structures in the pharmaceutical industry are associated with larger invention output, but inventions originating from assortative structures have lower average novelty and impact. Managerial Summary: A central challenge in knowledge-based industries is the design of collaborative teams to increase innovative output. In this paper, we show that firms in the pharmaceutical industry vary in the extent to which central inventors within a firm collaborate with peripheral inventors. Further, the ideal composition varies based on the desired innovative output: Firms with frequent collaborations between central inventors have higher inventive productivity, while firms with higher mixing between central and peripheral inventors generate inventions that are on average more novel and have higher impact. Results have implications for organizational design toward desired innovative outcomes, as well as management of strategic human capital.
Technology Differentiation, Product Market Rivalry and M&A Transactions

Prior work has mostly studied the relation between product market competition and M&A deals. In this paper, we study how competition and differentiation in technology space relates to M&A transactions. Relying on a new text-based method to map each firm’s competitive position in technology space and to measure the differentiation of a firm’s technology portfolio relative to all other firms, we find that firms with unique and differentiated technology are typical targets while firms with less differentiated technology are more likely to become acquirers. Moreover, firms with unique technology are particularly targeted by close competitors in the product market and receive a higher acquisition price, particularly in case of M&As with close product market firms. Our findings illustrate that a unique and differentiated technology portfolio is an important resource traded in the market for corporate control and a key driver of M&A deals, particularly between close competitors in the product market.
A Fuzzy Logic for Parameter Adaptation in Ant Colony Optimization Approach

:- The purpose of this study is to produce an ”adaptive Ant Colony System” in order to establish a balance between exploitation and exploration in terms of solving the Travel salesman problem. First we do a detailed investigation of several Ant Colony System Algorithm’s parameters. Second we will incorporate into the algorithm a Fuzzy Logic Controller, which will be utilized to alter the settings based on the algorithm’s reliable performance metrics. The parameter customization will proceed throughout the execution of the algorithm, providing for a dynamic parameter settings depending on the algorithm’s current performance. The adaptive algorithm will be examined on a set of TSP problems of varying sizes, and the results will be compared to those obtained using the standard algorithm and other studies in the same manner.
Determinants of earnings losses of displaced workers

Using an unusually rich matched employer-employee data set for Portugal, we studied the persistent earnings losses of workers displaced due to firm closure, collective dismissals and individual dismissals. We found that those losses are rather severe and persistent, representing around 50 percent of the pre-displacement wages, six years after the separation event. Those losses are largely explained by the joblessness experience of the displaced workers. We explored the sources of those losses, estimating a three-way high-dimensional fixed effects regression model, which enabled us to obtain worker, firm, and job title fixed effects. We found that the allocation into lower-paid job titles accounts for half of the total average wage loss. Sorting into firms also plays a significant role to explain the wage loss of displaced workers.
Meet me halfway: Financial analysts and strategic change ∗

Do financial analysts favor or inhibit firms’ strategic change? Two long-standing theories suggest opposite predictions. First, analyst coverage could foster strategic change by decreasing managerial agency costs, a common obstacle to change initiatives. Second, as analysts are reluctant to put in the effort to evaluate novel firm strategies, their presence would discourage change. We argue that these different views can be reconciled introducing firm transparency as a relevant factor: if firms are willing to share information, analysts’ search costs decrease and thus analysts are more likely to evaluate change initiatives. When firms are transparent, analysts promote strategic change. Using variation in resource allocation patterns as a proxy for strategic change, we find empirical support for our theory on a sample of 4,187 U.S. public firms.
Running head: SMARTPHONE PRESENCE AND IMPULSIVE DECISION MAKING 1 Smartphone Presence and Impulsive Decision Making An Online Experiment Regarding the Effects of Passive Smartphone Presence on the Decision-Making Process

Smartphones have become omnipresent in daily life as they enable their owners to be connected at any time and any place. Intriguingly, previous research on smartphone presence has shown that mere smartphone presence can result in reduced attentional performance. Here it is hypothesized that this is due to smartphones having become reinforced attentional capturers with instant gratification as the positive reinforcer. An online experiment with a between-subjects design was conducted to examine i) whether passive smartphone presence (as compared to smartphone absence) induced more impulsive responding in a smartphoneunrelated decision-making task, and ii) whether this effect was moderated by smartphone addiction. Participants first completed impulsivity and smartphone addiction questionnaires and then participated in an online version of the Iowa Gambling Task. The findings indicate that passive smartphone presence did not affect participants’ impulsivity during smartphoneunrelated decision making, nor was there a moderation effect by participants’ level of smartphone addiction or trait impulsivity. These results are critically discussed and recommendations for future empirical research are provided.
Food retailers’ sustainable brand image - exploring the barriers and challenges of implementing sustainability strategies in grocery stores

Food retailers and their local stores are considered to have an influential role in our society today, in terms of their impact in environmental and social issues. This qualitative case study aims to analyze the work of food retailers with sustainability, focusing on their processes of trying to make sustainable commitments reflect with consumers’ perception of the corporate brand image. This analysis also attempts to distinguish the role of local grocery stores in this development. The purpose is to get a better understanding in the barriers and challenges for food retailers to implement corporate sustainable strategies in local grocery stores to strengthen and establish a consistent sustainable brand image. To fulfill the purpose, data were collected through semi-structured interviews with five Swedish food retailers, together with secondary data from the organizations’ sustainability reports. Interviews were conducted with store managers and representatives from headquarters in order to gain insights from both store-level as well as headquarter-level. The case companies were chosen based on their ranking on the Sustainable Brand Index 2019; examining consumers’ perception of Swedish businesses’ brand in relation to sustainability. The findings of this study indicate that the role of the local grocery stores is of great importance for food retailers, to visualize and demonstrate their commitments in sustainability. This is actualized through various in-store activities where consumers encounter information of sustainable initiatives or engage with other more tangible activities. There do however exist barriers and challenges for food retailers to implement certain sustainable strategies in stores. These challenges are perceived to in a great extent be affected by how well the organizations facilitate store managers and headquarters to communicate and cooperate with each other. Including, how food retailers manage to continuously work with sustainability strategies in accordance with the market’s context. The consequence is believed to imply a lack of motivation and understanding among some store managers, as well as a difficulty among headquarters to adapt their strategies to the stores' local operations and demands. With potential inconsistencies in how local stores perceive and adopt sustainable strategies, it will most likely also affect the consistency in how sustainability is communicated towards consumers. Which evidently may also influence consumers’ associations of the food retailers’ sustainable brand image.
