Multi-business Firms' Corporate Renewal Decisions: Divestiture Governance Mode Choice of Corporate Spin-Offs and Equity Carve-Outs

The primary functions of corporate headquarters in multi-business ﬁrms are for entrepreneurial value creation and administrative loss prevention. A prominent way in which ﬁrms can renew their resources and capabilities is through divestitures. While the positive eﬀects of divestitures on parent companies are well documented, we know relatively less about the comparative assessment of different divestiture governance modes. To address this research gap, we focus on a comparative assessment of two divestiture governance modes — corporate spin-oﬀs and equity carve-outs — and examine under what conditions each divestiture governance mode is more likely to beneﬁt the parent company. Five divestiture corporate goals are identiﬁed: address business unit underper-formance, recover from corporate parent funding deﬁcit, reduce liability risk, parent company’s managerial refocus, and respond to third-parties’ interactions. We also explore two boundary conditions that inﬂuence the corporate parent’s divestiture governance
The Effect of Task Complexity on Time Estimation in the Virtual Reality Environment: An EEG Study

This paper investigated the effect of task complexity on time estimation in the virtual reality environment (VRE) using behavioral, subjective, and physiological measurements. Virtual reality (VR) is not a perfect copy of the real world, and individuals perceive time duration differently in the VRE than they do in reality. Though many researchers have found a connection between task complexity and time estimation under non-VR conditions, the influence of task complexity on time estimation in the VRE is yet unknown. In this study, twenty-nine participants performed a VR jigsaw puzzle task at two levels of task complexity. We observed that as task complexity increased, participants showed larger time estimation errors, reduced relative beta-band power at Fz and Pz, and higher NASA-Task Load Index scores. Our findings indicate the importance of controlling task complexity in the VRE and demonstrate the potential of using electroencephalography (EEG) as real-time indicators of complexity level.
Efficacy of K-Tape in Chronic Mechanical Low Back Pain

Efficacy of K-Tape in Chronic Mechanical Low Back Pain. Randomized Control Trial. A total of 30 patients were included as per pre define inclusion and exclusion criteria and randomly assigned into two groups, consisting of 15 patients in each group. Group A was given K-Tape along with standardized exercise program. Group B was given standardized exercise program along with moist hot pack for 4 weeks, 3 sessions per week one session per day. The patient’s outcome measures were assessed by visual analog scale, ODI and Goniometry for Lumbar Range of Motion. Measurements were recorded before and after the end of the treatment period. Results revealed that means and S.D of both group were significant (p=0.000 ) statically but clinically the Group of patients treated with K-Tape along with standardized exercise program managed pain (pre=7.50±1.21,post=0.71±0.37),ODI(pre=41±18.16,post= 8±4.49) and range of motion (flexion pre=31±5.04,post=50±10.12,extension pre=17±2.13,post=29±4.20 Rt side flexion pre=10±2.55,post=22±4.75 and Lt. side flexion pre=10±2.35, post=22±4.63, Rt side rotation pre= 8±1.27,post=19±2.65) Lt. side rotation pre=8±2.15, post=18±2.46 better than group of patients treated with standardized exercise program along with Moist hot pack in terms of pain (pre=7.81±1.16,post=2.35±1.27), ODI (pre=44±21.32,post=22±10.6) and range of motion (flexion pre=25±5.65,post=37±10.16, extension pre=15±2.55,post=21±5.32, Rt side flexion pre=10±2.35 post=15±2.28, Lt Side flexion pre=11±2.35, post=19±2.36, Rt side rotation pre=9±1.90 post=16. ±2.71, Lt Side rotation pre=8±1.63, post=15±3.15. The result of study suggests that both K-Tape and exercises improves the symptoms of chronic low back pain. Better improvement was shown by K-Tape group when compared with exercise group. Based on these results K-Tape and Exercise should be the treatment of choice for chronic mechanical low back pain rather than Exercise with HP.
Single-Event Effect Responses of Integrated Planar Inductors in 65-nm CMOS

This article describes a previously unreported single-event radiation effect in spiral inductors manufactured in a commercial CMOS technology when subjected to ionizing radiation. Inductors play a major role as the component determining the frequency of $LC$ tank oscillators, which is why any radiation effect in these passive components can have a detrimental impact on the performance of clock generation circuits. Different experiments performed to localize and characterize the single-event effect (SEE) response in a radiation-hardened PLL circuit are discussed and presented together with a hypothesis for the underlying physical mechanism.

Ensemble Stock Market Prediction using SVM,LSTM, and Linear Regression

Abstract: Stock forecasting is challenging because of stock volatility and dependability on external factors, such as economic, social, and political factors. This motivates investors to seek tools to identify stock trends to reap profits.In this research, we compared several heterogeneous ensembles for financial forecasting, including averaging, weighted, stacking, and blending ensembles. In addition, we used a random forest regressor as the baseline.Regression was used to predict the next day’s closing stock price. We used classification to label closing stock value as HIGH or LOW by comparing with the opening stock value of a particular company. We used Long Short Term Memory (LSTM) models, Linear Regression, and Support Vector Machines (SVM) as individual models. Further, we analyzed 10 years of historical data of the most active 20 companies of the NASDAQ stock exchange for implementing ensemble models.In conclusion, experimental results depict blending ensembles perform the best out of compared ensembles in financial forecasting. Further, they reveal SVM is under-performing, LSTM outputs are satisfactory, while linear regression produced promising results.Data: Data for this research was gathered from online available sources from the NASDAQ American stock exchange.We gathered data for most active 20 companies and 10 years of historical data from 21st September 2019 backwards. We used 40044 data points in total.
VALUE OF MRI (DWI &ADC) IN DIFFERENTIATING BENIGN AND MALIGNANT ORBITAL LESIONS

Background: Orbital and intraocular masses are relatively uncommon compared to other mass lesions of the body. It has been described that two-thirds of orbital tumors are benign and one third is malignant. Differentiating between these causes based on clinical findings may be difficult. Some lesions can be diagnosed easily depending on their characteristics on MRI but sometimes their characterization is still difficult. Diffusion weighted imaging (DWI) is an advanced MR-based technique which has the ability to characterize and differentiate morphologic features by measuring differences in apparent diffusion coefficient (ADC) and so can aid in differentiation of malignant and benign orbital lesions, which is focal to planning further patient management. Aim of the work: Is to investigate the utility of DW-MRI images and generated ADC values in the differentiation between benign and malignant orbital masses. Patient and Methods: This study included 21 cases (13 females and 8 males) proven to have an orbital mass by an available radiological study. Results: Of the 21 subjects, 10 out of 11 malignant lesions were correctly classified as malignant (TP) & all of the 10 benign lesions were correctly classified as benign (TN). A sensitivity of 90.9 % was achieved, with a specificity of 100 %. The Positive predictive value was 100 %, while the negative predictive value was 90.9%. Conclusion: DWI and ADC maps with ADC value calculations are useful for differentiating between malignant and benign orbital tumors. Apparent diffusion coefficient value can solve some clinical problems of the orbit that affect patient management.
Adsorption Performance of La(III) and Y(III) on Orange Peel: Impact of Experimental Variables, Isotherms, and Kinetics

To alleviate the environmental problem associated with rare earth wastewater, this research applied waste orange peel (OP) for the adsorption of La(III) and Y(III) from aqueous solution. The adsorption properties of orange peel are characterized using scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR), and the participation of hydroxyl and other oxygen-containing groups that promote the physical-chemical interaction is verified. Batch adsorption results suggest that orange peel possesses a satisfactory adsorption performance for La(III) and Y(III). The optimal adsorption conditions were obtained at pH of 6, temperature of 40°C, appropriate dosage of 2 g/L and 3 g/L, contact time of 30 min, and initial ion concentration of 32 mg/L. Under the same condition, adsorption performance of La(III) is better than that of Y(III). The experimental data is well fitted by the Langmuir isotherm model with correlation coefficient R 2 > 0.9 and the minimum standard error values. Equilibrium results show that Langmuir monolayer adsorption capacity of La(III) and Y(III) onto orange peel is up to 37.61 and 31.10 mg/g. The fitting results of kinetics prove that the adsorption process of La(III) and Y(III) follows the pseudosecond-order model. Thus, natural orange peel as a recyclable biosorbent has potential economic and applicative benefits to remove La(III) and Y(III) from aqueous solutions.
The Impact of Total Foreign Debt on the Economic Growth of Egypt (1980-2018)

Foreign debt is considered to be a source of income for countries. If foreign debt is managed well and directed towards productive projects, then it might enhance the countries’ economic growth. However, foreign debt has many costs that might cause deterioration in the economy. This study aims to investigate how total foreign debt impacts the economic growth of Egypt for a time period of 39 years (1980-2018). In the methodology, descriptive statistics, unit root tests, Johansen co-integration and Vector Error Correction Model (VECM) are used. The results show that total foreign debt exerts a significant long run negative impact on the Egyptian economic growth, while the results are insignificant in the short run.
The repercussions of COVID-19 on the stock market of the Tourism industry

The COVID-19 pandemic has already caused important negative consequences on the tourism industry globally. The lockdown measures suspended the tourism activities, and many tourists preferred to abstain from these activities in fear of the virus infection. As a result, investors have abandoned tourism-related companies’ stocks, impacting, even more, the tourism industry. In this paper, we examine the biggest companies’ stocks related to tourism, from the fields of airlines, cruise lines, resorts, hotel groups, travel agents, and other tourism activities (such as car rentals). Using time series analysis, we test and analyze the effect of the COVID-19 pandemic on these stocks, and we derive the spillover effects through the impulse-response functions from each company to the others. Based on our findings, the tourism-related stocks were affected by COVID-19, as shown by the causality technique, and, moreover, the tourism-related companies are interconnected with each other, transmitting the shock from a specific tourism industry to the others, as shown by the impulse-response functions.
A highly contiguous nuclear genome assembly of the mandarinfish Synchiropus splendidus (Syngnathiformes: Callionymidae)

Abstract The fish order Syngnathiformes has been referred to as a collection of misfit fishes, comprising commercially important fish such as red mullets as well as the highly diverse seahorses, pipefishes, and seadragons—the well-known family Syngnathidae, with their unique adaptations including male pregnancy. Another ornate member of this order is the species mandarinfish. No less than two types of chromatophores have been discovered in the spectacularly colored mandarinfish: the cyanophore (producing blue color) and the dichromatic cyano-erythrophore (producing blue and red). The phylogenetic position of mandarinfish in Syngnathiformes, and their promise of additional genetic discoveries beyond the chromatophores, made mandarinfish an appealing target for whole-genome sequencing. We used linked sequences to create synthetic long reads, producing a highly contiguous genome assembly for the mandarinfish. The genome assembly comprises 483 Mbp (longest scaffold 29 Mbp), has an N50 of 12 Mbp, and an L50 of 14 scaffolds. The assembly completeness is also high, with 92.6% complete, 4.4% fragmented, and 2.9% missing out of 4584 BUSCO genes found in ray-finned fishes. Outside the family Syngnathidae, the mandarinfish represents one of the most contiguous syngnathiform genome assemblies to date. The mandarinfish genomic resource will likely serve as a high-quality outgroup to syngnathid fish, and furthermore for research on the genomic underpinnings of the evolution of novel pigmentation.
Healed plaque erosion as a cause of recurrent vasospastic angina: a case report

Abstract Background Recurrent vasospastic angina sometimes occurs. Fresh thrombi have been known to arise without plaque rupture at coronary spasm sites due to blood flow stagnation and intimal erosion caused by vasospasms. The relationship between recurrence of vasospastic angina and thrombus formation remains unclear. Case summary A 67-year-old man presented with sudden chest pain at rest. Electrocardiography and coronary angiography indicated vasospastic angina. His chest pain persisted despite the administration of benidipine, isosorbide mononitrate, nicorandil, and nifedipine. Coronary angiography performed one month after initial presentation showed stenosis refractory to isosorbide administration. Optical coherence tomography revealed a healed plaque, and a stent was deployed. The patient remained symptom-free at 1-year follow-up. Discussion Prolonged coronary vasospasm with limited coronary blood flow could induce total occlusion of the coronary artery, and acute thrombus formation, which resulted in healed plaque erosion. When vasospastic angina cannot be controlled, rapidly progressive stenosis caused by healed plaque erosion could be its underlying cause and mechanism. This report indicates that antiplatelet therapy may be a preventive option for future recurrent vasospastic angina, especially in those caused by healed plaques.
The Effects of Using Pomegranate (Punica granatum) Seed Powder on Quality Parameters of Model System Chicken Meat Emulsions

This study aimed to investigate the effects of using 1%, 3% and 5% pomegranate seed powder (PSP) on model system chicken meat emulsion (CME) quality parameters. For this purpose, the properties of the emulsion samples prepared using different amounts of PSP were compared with the control group prepared with 70% chicken breast meat, 18% chicken skin, 10% water, 1.5% salt and 0.5% sodium tripolyphosphate (STPP). Chemical composition, pH, emulsion stability, water holding capacity, cooking yield, and color were analyzed in emulsion samples. TBARs and peroxide values of the samples were determined on days 0, 3, 5 and 7 during storage. Use of pomegranate seed powder in emulsion formulation resulted a decrease in b* and a* values. At the same time, with the addition of pomegranate seed powder, there was no difference in the protein values of the raw samples and the moisture, ash and pH values of the cooked samples. It was also observed that pH values, water holding capacity and cooking efficiency of emulsions increased with the increasing levels of PSP. Both peroxide and TBARs values were lower in emulsion samples formulated with PSP on 7 d compared to the control group.
Surgical versus non-operative initial management of post-endoscopic retrograde cholangiopancreatography perforation: a systematic review and meta-analysis

Background In the present study we performed a systematic review and meta-analysis regarding the initial management of perforations following endoscopic retrograde cholangiopancreatography (ERCP). Method A systematic review and meta-analysis was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. Result In total, 10 comparative studies and 223 patients with post-ERCP perforations were included in the present study. In type I and II perforations, the success rate of initial surgical management was higher compared to the non-operative management (NOM) group (P=0.09 and P=0.02, respectively). There was no statistically significant difference in mortality rates or length of hospital stay between initial surgical and NOM management for any type of perforation. Conclusions The current meta-analysis demonstrated the significance of the initial management of patients with post-ERCP perforations. Whether a surgical or an endoscopic approach is chosen, the patient should immediately be evaluated by an experienced surgeon or endoscopist.
Deep Reinforcement Learning Model for Blood Bank Vehicle Routing Multi-Objective Optimization

: The overall healthcare system has been prioritized within development top lists worldwide. Since many national populations are aging, combined with the availability of sophisticated medical treatments, healthcare expenditures are rapidly growing. Blood banks are a major component of any healthcare system, which store and provide the blood products needed for organ transplants, emergency medical treatments, and routine surgeries. Timely delivery of blood products is vital, especially in emergency settings. Hence, blood delivery process parameters such as safety and speed have received attention in the literature, as well as other parameters such as delivery cost. In this paper, delivery time and cost are modeled mathematically and marked as objective functions requiring simultaneous optimization. A solution is proposed based on Deep Reinforcement Learning (DRL) to address the formulated delivery functions as Multi-objective Optimization Problems (MOPs). The basic concept of the solution is to decompose the MOP into a scalar optimization sub-problems set, where each one of these sub-problems is modeled as a separate Neural Network (NN). The overall model parameters for each sub-problem are optimized based on a neighborhood parameter transfer and DRL training algorithm. The optimization step for the sub-problems is undertaken collaboratively to optimize the overall model. Pareto-optimal solutions can be directly obtained using the trained NN. Specifically, the multi-objective blood bank delivery problem is addressed in this research. is that once the trained model is available, it can In particular, the proposed model outperformed other state-of-the-art MOP solutions such as Genetic Algorithms and Simulated Annealing.

The study reported in this article empirically explores the deployment of social creativity in cultural initiatives struggling with issues of (un)sustainable urban development in their city (Hanover, Germany). On the one hand, individual characteristics of creativity are explored. On the other hand, forms of collective creativity are of interest, as well as the synthesis of individual and collective creativity under the concept of social creativity.
The Enhancement of Drought Tolerance in Arabidopsis Plants Induced by Pretreatment with Sulfur Dioxide

Sulfur dioxide (SO2) is a common air pollutant that has multiple effects on plants. Here, the effect of prior exposure to SO2 on the improvements of drought tolerance and possible regulation mechanisms were investigated in Arabidopsis plants. The experimental results showed that pre-exposure to 30 mg/m3 SO2 for 72 h could reduce leaf water loss, and enhance the drought tolerance of Arabidopsis plants. SO2 pre-exposure decreased leaf stomatal conductance (Gs) and transpiration rate (Tr) but increased net photosynthetic rate (Pn), water use efficiency (iWUE) and photosynthetic pigment contents under drought conditions. Importantly, the activities of superoxide dismutase (SOD) and peroxidase (POD) were significantly increased, while the contents of hydrogen peroxide (H2O2) and malondialdehyde (MDA) were decreased in SO2-pretreated Arabidopsis plants under drought stress. Additionally, the activity of o-acetylserine(thio)lyase (OASTL) and the content of cysteine (Cys), the rate-limiting enzyme and the first organic product of sulfur assimilation, were increased significantly in drought-stressed plants after SO2 pretreatment, along with the increases of other thiol-containing compounds glutathione (GSH) and non-protein thiol (NPT). Meanwhile, SO2 pre-exposure induced a higher level of proline accumulation, accompanied by the increased activity of proline synthase P5CS, the decreased activity of proline dehydrogenase ProDH and the corresponding alteration of gene transcription. Collectively, the enhanced drought tolerance afforded by SO2 might be related to the improvement of plant photosynthesis, antioxidant defense, sulfur assimilation and osmotic adjustment. These findings provide new insights in understanding the role of SO2 in plant adaptation to environmental stress.
