Cardiogenic Parameters Effectively Predict Hemorrhagic Transformation in Patients with Non-Large Artery Atherosclerosis Infarction

Background: Non-large artery atherosclerosis (LAA) infarcts are relatively rare compared to LAA type infarcts. Hemorrhagic transformation (HT) is one of the complications of acute ischemic stroke (AIS), and we aim to investigate the risk factors for the development of HT in patients with non-LAA type AIS.Patients and methods：From January 2015 to January 2020, we included a total of 52 patients with non-LAA type AIS who met the criteria for the occurrence of HT, for which 136 patients without HT were matched. Patients were followed up every 3 months by phone or in the clinic, with a minimum of 1 year of follow-up per patient. The risk factors associated with prognosis were derived after univariate analysis and multifactorial logistic regression analysis, and a nomogram model was developed based on these risk factors. The accuracy of the model was evaluated by creating a calibration plot and the receiver operating characteristic curve (ROC). Results: Through univariate analysis and logistics regression analysis, we found that the patient's creatine kinase-MB (CK-MB), ejection fraction (EF) and platelets (PLT) were independently related to the HT in patients with non-LAA type AIS. We accordingly developed smoothing curves to predict the probability of HT and found that the HT rate increased with increasing CK-MB and decreased with increasing EF and PLT. The nomogram based on these three factors had an area under curve (AUC) of 0.875 for the development group and 0.889 for the external validation group. The calibration plot showed a good prediction accuracy.Conclusions: Patients with non-LAA type AIS are relatively uncommon and presenting with HT is even rarer. Our nomogram built on cardiogenic parameters and PLT can accurately predict the occurrence of HT in these non-LAA type AIS patients, which has good clinical significance.
On Effect of Planar Scaling on Microstrip Patch Antenna Performance

This paper aims at investigating the effect of planar scaling on Microstrip patch antenna performance. To this end, nine antennas with different sizes are fabricated on the same FR4 substrate with thickness of 1mm with different scale factors. Results indicate some deviations between the obtained expected, simulated and measured resonant frequency which could be mainly due to the truncation error effect, and the SMA connector effect in the scaling process. All the influential factors are studied in detail through the paper. Detailed discussion on the scaling process and its effect on the antenna performance would be presented.

Agrobacterium tumefaciens mediated transformation of chicory (Cichorium intybus L.) with Mytilus galloprovincialis foot protein type five (MGFP-5)

Mytilus galloprovincialis foot protein type 5 (Mgfp-5) can be used as medical adhesive or in underwater environments due to its significant adhesive ability and biodegradable properties. To obtain sufficient Mgfp-5 for further study, genetic engineering has been abundantly used, while plant genetic engineering was rarely applied. This study reports an efficient protocol for the direct regeneration of chicory (Cichorium intybus L.), with a regeneration frequency of 79.18% in the case of inoculation on MS+1.5 mg/L 6-BA+0.2 mg/L NAA medium. The plant expression vector pRI101-Mgfp of the Mgfp-5 gene was transformed into chicory via Agrobacterium mediation. After plant selection and regeneration, regenerated plants with resistance were successfully obtained. The efficient transformation system of the Agrobacterium-mediated genetic transformation consists of leaf explants immersed in Agrobacterium at O.D. (600) of 0.6 for 10 min after being pre-cultured for 3 d, followed by co-culture for 3 d. Then, these explants were transferred to medium containing 50 mg/L kanamycin selection power. As proved via PCR, RT-PCR, and Western blot analysis, the Mgfp-5 gene was integrated into the chicory genome, accompanied by normal transcript and expression, as well as stable genetic transformation and inheritance. These results underpin future research toward providing a feasible method for the production of Mgfp-5 protein.
Identifying and describing databases relevant to health and safety at work

The Health and Safety Executive (HSE) currently uses well-established sources of data on workplace injury and ill health to inform its policies and programmes. The primary sources of data are RIDDOR and the Labour Force Survey (LFS). However, the HSE is aware of other databases, and studies, surveys and reviews which are relevant to the contemporary landscape of health and safety research, policy and management. The project identifies, describes, evaluates and catalogues data sources that could inform these areas and which are either currently unknown to or not fully exploited by the HSE. The bibliography presented covers 53 data sources of substance. Ten sources were categorised as ‘of importance’ and evaluated and described in detail. Two sources were believed to be of particular importance to the HSE: the Whitehall II Study and the English Longitudinal Study of Ageing. The former contains more information of relevance. This report and the work it describes were funded by the Health and Safety Executive (HSE). Its contents, including any opinions and/or conclusions expressed, are those of the authors alone and do not necessarily reflect HSE policy.
The Optimal Extraction Path of Exhaustible Resources under Environment Control

Assuming in the perfectly competitive market, using the optimal control theory and making the social welfare as the maximization target, the paper studies on environment control which impacts the optimal extraction path of exhaustible resource. The special case result shows that: reserve and the changes of environment capacity function and curve are influenced by original reserve, discounted value, the absolute ratio of green environment flow to resource extraction quantity, and marginal cost.
Design Guideline for Ball Impact Test Apparatus

The ball impact test is developed as a package-level measure of the hoard-level reliability of solder joints in the sense that it leads to brittle intermetallic fracturing, similar to that from a board-level drop test. Following classical structural dynamics principles, the ball impact test process is analyzed to provide insights into transient characteristics of this particular test methodology. A design guideline for the ball impact test apparatus based on characteristics of the measured impact force profile is proposed.
Grazing pressure on forage availability of Brachiaria decumbens

The objective of this research was to evaluate the effect of two grazing pressures on the availability of Brachiaria Decumbens forage. The research was carried out at the Quilichao Experimental Substation, of the International Center for Tropical Agriculture (CIAT), Cauca, Colombia. Eight initial availabilities of 4 300, 4 400, 4 800, 4 900, 6 000, 7 200, 17 400 and 18 900 kg of MSV per hectare were evaluated two initial grazing pressures: low, 1000 PV / 100 kg MSV and high, 1500 kg PV / 100 kg MSV. The design was of random blocks, with four replicas. The area was divided into 12 subplots per treatment and forage availability was measured at the beginning, at 2, 4, 6, 22, 26, 30, 46, 54, 70, 74 and 96 h of grazing. Commercial bullocks of the zebu race were used, with an average weight of 350 kg. Results show that there are statistical differences (p < 0,05) between initial high and low grazing pressures. Therefore, it is concluded that, the higher the initial availability, the higher the percentage of leaf area and stems, but the lower percentage of dead material, however, the leaf stem ratio decreases as the initial availability increases.
READINESS FOR BLENDED LEARNING: UNDERSTANDING ATTITUDE OF UNIVERSITY STUDENTS

Information technology (IT) has provided new means for learning delivery outside of conventional classrooms. Leveraging on IT, blended learning is an approach which takes advantage of the best that both the classroom and online learning can provide. To help institutions of higher learning (IHLs) improve their understanding of how students view blended learning and formulate a strategy to successfully implement blended learning, the main objective of this paper is to examine how the attitude of students towards different learning aspects could influence their readiness for blended learning. We conceptualized six learning aspects in a research model and then collected responses from 201 full-time undergraduate students to validate the model. Analyses revealed three key findings. First, the use of technology in education was not a hindrance to the students. Second, blended learning adaptability, which was modelled as a second-order formative construct and formed by four first-order reflective constructsâ€”attitude towards online learning, study management, online interaction, and learning flexibilityâ€”had a positive relationship with student readiness for blended learning. Third, attitude towards classroom learning had a negative relationship with student readiness for blended learning. An understanding of student attitude towards different learning aspects can be critical in the assessment of student readiness for blended learning, which is a prerequisite for successful implementation of blended learning.

The polymorphism in g.1256G>A of bovine pituitary specific transcription factor-1 (bPIT-1) gene and its association with body weight of Pasundan cattle

Bovine Pituitary specific transcription factor 1 (bPit-1) is one of amino acid that controling pituitary gland in mammals. The pituitary gland is important for secretion of growth hormone from growth genes. This study was carried out to detect polymorphism in the exon 6 of bPit-1 (g.1256G>A) in Pasundan cattle using PCR-RFLP method and its association with body weight. Total of 69 heads (15 males and 54 females) of Pasundan cattle from breeding station (BPPIBT-SP Ciamis, West Java) were used in this study. Research showed that two genotypes of bPit-1/HinfI gene were identified in this study i.e GG (0.90) and AG (0.10) with allele frequencies of 0.05 (A) and 0.95 (G). The polymorphic informative content (PIC) and number of effective allele (ne) values were 0.09 (low) and 1.11. respectively. The Chi-square (χ2) value in the population studied was 0.20 and in Hardy-Weinberg equilibrium (χ2<5.99). It was concluded that the polymorphism of bPit-1/HinfI in Pasundan cattle included of low category and was not associated with body weight.
Operational implications of early supplier involvement in semiconductor manufacturing firms: A case study

Purpose – Existing earlier supplier involvement (ESI) models mostly emphasize the product development perspective with limited attention to the process development dimension. Towards this end, this paper aims at a tailored framework for semiconductor manufacturing firms by taking into account the implementation of ESI in process development as well as product development.Design/methodology/approach – A number of well‐recognized propositions are examined through a case study of MIC Semiconductors Asia. Based on observations from the case study, the problems of existing frameworks are analyzed and accordingly possible solutions are explored.Findings – The case study reveals the importance of process development in ESI implementation. It is imperative to build up on some fundamentals of the company before ESI can be carried out successfully. Also observed is that the effectiveness of a supplier selection criterion should be gauged from the performance of the suppliers. It is also found out what type of relat.
Reliability measurement of fault-tolerant onboard memory system under fault clustering

Advances in spaceborne vehicular technology have made possible the long-life duration of the mission in harsh cosmic environments. Reliability and data integrity are commonly emphasized requirements of spaceborne solid-state mass storage systems, because faults due to the harsh cosmic environments - such as extreme radiation - can be experienced throughout the mission. Acceptable dependability for these instruments have been achieved by using redundancy and repair. Reconfiguration (repair) of memory arrays using spare memory lines is the most common technique for reliability enhancement of memories with faults. Faulty cells in memory arrays are known to show spatial locality. This physical phenomenon is referred to as fault clustering. This paper initially investigates a quadrat-based fault model for memory arrays under clustered faults to establish a sound foundation of measurement. Then, long-life dependability of a fault-tolerant spaceborne memory system with hierarchical active redundancy, which consists of spare columns in each memory module and redundant memory modules, is measured in terms of reliability (i.e., the conditional probability that the system performs correctly throughout the mission) and mean-time-to-failure (MTTF i.e., the expected time that a system will operate before it fails).
Making Use of Critical Management Theory: A Discursive Intervention for Employee Empowerment

Critical management scholars have examined employee oppression (i.e., wage inequity, union busting, marginalization and silencing), by leveling criticism against traditional management practices, arguing for more pluralistic relationships across agencies. Despite this action-oriented charge, the field is currently lacking in its potential to provide employees tools they need to create a more equitable balance of power in the workplace. To address this gap, this paper describes an organizational intervention that can be used by employees to openly discuss and take action to remedy the problem of power inequity. The paper also includes a discussion of ethical constraints related to the intervention.
MDR1 polymorphisms are not related to Xeliri and Xelox chemoresistance in colorectal cancer

Background Multidrug resistance member 1 (MDR1) is located on chromosome 7 and encodes P-glycoprotein (Pgp), which is universally accepted as a drug resistance biomarker. MDR1 polymorphisms may change either the protein expression or function, suggesting its possible association with cancers, including colorectal cancer (CRC). Thus, this study aimed to determine the effects of MDR1 polymorphisms on the drug response of Saudi CRC patients.Methods DNA samples were obtained from 62 CRC patients and 100 healthy controls. The genotypes and allele frequencies of the MDR1 polymorphisms G2677T and T1236C were determined by polymerase chain reaction–restriction fragment length polymorphism (PCR-RFLP). Results No significant difference was observed in the genotype distribution and allele frequency of T1236C between the CRC the patients and the controls. However, G2677T was found to play a highly significant protective role against the progression of CRC. Moreover, the results showed that none of the genotypes in SNPs T1236C and G2677T affected chemoresistance to Xeliri and Xelox.Conclusions T1236C in the MDR1 gene is not related to CRC risk, and G2677T protects against the development of CRC. Both MDR1 polymorphisms are not associated with the risk of chemoresistance.
An Experimental Study on Tip Vortex Cavitation Suppression in a Marine Propeller

Normally, tip vortex cavitation (TVC) is first observed at a certain location behind the tips of propeller blades. Therefore, TVC is important for naval ships and research vessels that require raising the cavitation inception speed to maximum possible values. The concepts for alleviating the tip vortex are summarized by Platzer and Souders (1979), who carried out a thorough literature survey. Active control of TVC involves the injection of a polymer or water from the blade tip. The main effect of such mass injection (both water and polymer solutions) into the vortex core is an increase in the core radius, consequently delaying TVC inception. However, the location of the injection port needs to be selected with great care to ensure that the mass injection is effective in delaying TVC inception. In the present study, the authors propose a semiactive control scheme that is achieved by attaching a thread at the propeller tip. The main idea of a semiactive control is that because of its flexibility, the attached thread can be sucked into the low-pressure region closer to the vortex core center. An experimental study using a scale model was carried out in the cavitation tunnel at the Seoul National University. It was found that a flexible thread can effectively suppress the occurrence of TVC under the design condition for a model propeller.
Prediction of postoperative atrial fibrillation using the electrocardiogram: A proof of concept

Hospital patients recovering from major cardiac surgery are at high risk of postoperative atrial fibrillation (POAF), an arrhythmia which can be life-threatening. With the development of a tool to predict POAF early enough, the development of the arrhythmia could be potentially prevented using prophylactic treatments, thus reducing risks and hospital costs. To date, no reliable method suitable for autonomous clinical integration has been proposed yet. This thesis presents a study on the prediction of POAF using the electrocardiogram. A novel P-wave quality assessment tool to automatically identify high-quality P-waves was designed, and its clinical utility was assessed. Prediction of paroxysmal atrial fibrillation (AF) was performed by implementing and improving a selection of previously proposed methods. This allowed to perform a systematic comparison of those methods, and to test if their combination improved prediction of AF. Finally, prediction of POAF was tested in a clinically relevant scenario. This included studying the 48 hours preceding POAF, and automatically excluding noise-corrupted P-waves using the quality assessment tool. The P-wave quality assessment tool identified high-quality P-waves with high sensitivity (0.93) and good specificity (0.84). In addition, this tool improved the ability to predict AF, since it improved the precision of P-wave measurements. The best predictors of AF and POAF were measurements of the variability in P-wave timeand morphological features. Paroxysmal AF could be predicted with high specificity (0.93) and good sensitivity (0.82) when several predictors were combined. Furthermore, POAF could be predicted 48 hours before its onset with good sensitivity (0.74) and specificity (0.70). This leaves time for prophylactic treatments to be administered and possibly prevent POAF. Despite being promising, further work is required for these techniques to be useful in the clinical setting.

Echo chambers revisited: The (overwhelming) sharing of in-group politicians, pundits and media on Twitter

Analyzing four years of data from a random sample of about 1.5 million Twitter users (and about 180,000 politically engaged users), we revisit the debate regarding the extent to which social media users live in political ``echo chambers'' with two new analytic approaches. First, we focus on the sharing of content from political elites, arguably the most influential and politically active actors, and estimate the extent to which ordinary users share messages from politicians, pundits, and news media of the same versus opposing ideology. Second, we examine the extent to which this sharing is annotated by users before it is shared (``quoted retweets'') and the tone of these annotations (e.g., do users share out-group content with negative commentary? ). We find clear patterns indicative of echo-chambers: the politically engaged users analyzed share in-group messages from elites 14 times more frequently than out-group messages; and in the rare instances when out-group information is shared, a non-trivial amount of times it is accompanied by negative comments. These patterns emerge after accounting for how many in-group versus out-group elites a person follows, and are robust to the political interest of the user or extremity of the elite accounts, the topic of the tweet, and the type of political elite source of the original message. In line with previous research, we also find that this echo chamber is especially pronounced among conservative users, who are about twice as likely as liberals to share in-group vs out-group content. These findings have important implications for how we theorize and study online echo chambers.
