Clinical Perspective Grading , staging and scoring of left-ventricular hypertrophy , left-ventricular dilatation , asymptomatic left-ventricular dysfunction and chronic heart failure

A trend has developed within medicine and surgery to organize, assess and act on clinical information within the structure of universally understood data management systems. Examples are widespread in a number of specialties; however, the field of oncology has probably been the most successful in assimilating data management systems into daily clinical practice. Such schemes allow information on a patient’s disease to be graded, staged or scored and represented numerically or alphabetically. The attribute assigned conveys information to the physician on: (a) the severity of a disease; (b) further investigations indicated; (c) the nature and timing of further treatment or surgical intervention, and most importantly, (d) the prognosis for the patient. Within oncology the terms grading and staging have by tradition, become synonymous with describing particular aspects of the natural history of malignancy. The grading classification has its basis in cytology and histology, and purveys information on the cellular and architectural changes in the structure of a given tissue. As such, grading of disease progression has been widely used in documenting dysplastic changes of epithelial cells and forms an integral part of the clinical reporting of tissue biopsies for suspected cellular atypical. Often this will take the form of a simple description on the state of cellular differentiation (well differentiated, I; moderately differentiated, II, or poorly differentiated, III). The term staging has been attributed to the numerical description of disease on a more systemic level based on: physical examination, serology, histology, radiology and endoscopy. In the field of oncology, staging is often used to convey information on the infiltration and metastatic progression of tumours. The most commonly used
School Integration Limits the Ability of Local Norms to Diversify Gifted Programs: A Mathematical Analysis with Implications Related to the Achievement Gap

Experts within gifted education have advocated for the use of local norms when selecting students for gifted programs, instead of national-level norms. Local norms compare students to their immediate peers to identify gifted students and are believed to produce a more diverse gifted program. However, district integration limits the ability of local norms to diversify gifted programs, a fact that has been almost completely overlooked in gifted education scholarship. Through a simplified example, we show that local building-level norms are best at diversifying gifted programs when schools are highly segregated. Conversely, when achievement gaps are present and a uniform admissions cutoff is applied, building-level norms in highly integrated schools produce highly segregated gifted programs. In short, the use of building-level local norms trades one form of segregation for another. Implications and recommendations for gifted education and beyond are explored.

Hybrid wireless smart sensor network for full-scale structural health monitoring of a cable-stayed bridge

Rapid advancement of sensor technology has been changing the paradigm of Structural Health Monitoring (SHM) toward a wireless smart sensor network (WSSN). While smart sensors have the potential to be a breakthrough to current SHM research and practice, the smart sensors also have several important issues to be resolved that may include robust power supply, stable communication, sensing capability, and in-network data processing algorithms. This study is a hybrid WSSN that addresses those issues to realize a full-scale SHM system for civil infrastructure monitoring. The developed hybrid WSSN is deployed on the Jindo Bridge, a cable-stayed bridge located in South Korea as a continued effort from the previous year's deployment. Unique features of the new deployment encompass: (1) the world's largest WSSN for SHM to date, (2) power harvesting enabled for all sensor nodes, (3) an improved sensing application that provides reliable data acquisition with optimized power consumption, (4) decentralized data aggregation that makes the WSSN scalable to a large, densely deployed sensor network, (5) decentralized cable tension monitoring specially designed for cable-stayed bridges, (6) environmental monitoring. The WSSN implementing all these features are experimentally verified through a long-term monitoring of the Jindo Bridge.
Algorithm of Helmet Wearing Detection Based on AT-YOLO Deep Mode

: The existing safety helmet detection methods are mainly based on one-stage object detection algorithms with high detection speed to reach the real-time detection requirements, but they can’t accurately detect small objects and objects with obstructions. Therefore, we propose a helmet detection algorithm based on the attention mechanism (AT-YOLO). First of all, a channel attention module is added to the YOLOv3 backbone network, which can adaptively calibrate the channel features of the direction to improve the feature utilization,and a spatial attention module is added to the neck of the YOLOv3 network to capture the correlation between any positions in the feature map so that to increase the receptive field of the network. Secondly, we use DIoU (Distance Intersection over Union) bounding box regression loss function, it not only improving the measurement of bounding box regression loss but also increases the normalized distance loss between the prediction boxes and the target boxes, which makes the network more accurate in detecting small objects and faster in convergence. Finally, we explore the training strategy of the network model, which improves network performance without increasing the inference cost. Experiments show that the mAP of the proposed method reaches 96.5%, and the detection speed can reach 27 fps. Compared with other existing methods, it has better performance in detection accuracy and speed.
Monetary Policy and Unemployment—A Study on the Relationship Exists in the United States

This paper intends to make research on the relationship between monetary policy and unemployment of the United States from the first quarter of 1983 to the second quarter of 2018. Data is collected and later divided into two groups, namely an ex-crisis group and a post-crisis group, based on the event of the 2008 world financial crisis. This paper uses an extended version of the original Taylor’s rule by adding the concept of unemployment degree. The results suggest that in both periods, the unemployment gap degree does make a positive impact on the Fed interest rate and has a constantly significant impact on the Fed rate. As a result, Central Banks should adopt an easy monetary policy to stimulate the domestic economy from recession.
Effect of ozone treatment on softwood soda lignin-based water reducer performance for concrete

A lignin-based water reducer for concrete was prepared from softwood soda lignin. The soda lignin and the lignin-polyethylene glycol (PEG) derivative were modified with ozone to improve their performance as water reducers. The performance of ozone-treated soda lignin was superior than untreated soda lignin and commercial lignosulfonate-type water reducers in the mortar flow test. The soda lignin treated with a high ozone charge showed better performance than lignin treated with a low ozone charge. The ozone treatment improved the performance of the lignin-PEG derivative water reducer as well. The lignin-PEG derivative water reducer with a longer PEG chain length showed better performance than that of the shorter PEG chain. The zeta potential of cement suspension with the ozone-treated soda lignin showed a higher negative value than the untreated soda lignin. The data of zeta potential analysis suggested that the electrostatic repulsion force of cement particles with the ozone-treated lignin would be larger than the untreated lignin.
Optimal energy decay rates for abstract second order evolution equations with non-autonomous damping

We consider an abstract second order non-autonomous evolution equation in a Hilbert space H : u″ + Au + γ(t)u′ + f(u) = 0, where A is a self-adjoint and nonnegative operator on H, f is a conservative H-valued function with polynomial growth (not necessarily to be monotone), and γ(t)u′ is a time-dependent damping term. How exactly the decay of the energy is affected by the damping coefficient γ(t) and the exponent associated with the nonlinear term f? There seems to be little development on the study of such problems, with regard to non-autonomous equations, even for strongly positive operator A. By an idea of asymptotic rate-sharpening (among others), we obtain the optimal decay rate of the energy of the non-autonomous evolution equation in terms of γ(t) and f. As a byproduct, we show the optimality of the energy decay rates obtained previously in the literature when f is a monotone operator.
Stability-Indicating High-Performance Liquid Chromatography and Thin-Layer Chromatography Methods for the Determination of Cyclobenzaprine Hydrochloride and Asenapine Maleate

Two sensitive, specific, and selective stability-indicating chromatographic methods were developed for the determination of cyclobenzaprine HCl (CZ) and asenapine maleate (AS) in pure forms, in the presence of their degradation products and in their pharmaceutical formulations. The first method was an isocratic reversed-phase high-performance liquid chromatography (RP-HPLC). Analysis was performed on cyano column using a mobile phase consisting of acetonitrile—(0.05 m) potassium dihydrogen phosphate buffer (pH 3 ± 0.1) (70:30, v/v) with a flow rate of 1.5 mL min−1 and ultraviolet (UV) detection at 290 nm for the determination of CZ, and methanol—( 0.05 m) potassium dihydrogen phosphate buffer (pH 6 ± 0.1) (70:30, v/v) with a flow rate of 1.5 mL min−1 and UV detection at 220 nm for the determination of AS. The second method was thin-layer chromatography (TLC), using silica gel 60 F254 plates and toluene—methanol—chloroform-ammonia solution 33% (5:3:6:0.1, by volume) as the mobile phase for the two drugs. The spots were scanned densitometrically at 290 and 220 nm for the determination of CZ and AS, respectively. The methods were validated according to the International Conference on Harmonization (ICH) guidelines, and the acceptance criteria for linearity, accuracy, precision, specificity, and system suitability were met in all cases. The linearity ranges were 2.5–25 μg mL−1 for the RP-HPLC method and 5–50 μg band−1 for the TLC method for both drugs. The limits of detection for the RP-HPLC method were 0.250 and 0.578 for CZ and AS, respectively, while the limits of quantification were 0.758 and 1.572 for CZ and AS, respectively. The limits of detection for the TLC method were 1.355 and 1.284 for CZ and AS, respectively, while the limits of quantification were 4.472 and 3.891 for CZ and AS, respectively. The results were compared statistically at a 95% confidence level with the reported methods. There were no significant differences between the mean percentage recoveries and the precisions of the two methods.
Improving Writing Ability and Independent Learning Using Problem Based Learning (PBL) Assisted by Serial Image Media

—This research was conducted due to the low ability of students in writing procedural texts and the lack of independent learning of students. This is due to the difficulty of students developing procedural texts in supporting the achievement of learning objectives and the lack of student motivation to learn independently. This study aims to determine the increase in the ability to write procedural texts and the independent learning of students using problem-based learning ( PBL )assisted by serial image media. This research method is a quasi-experimental type nonequivalent control group design. The research subjects were students of class VII A and VII B at one of the Cimahi high schools, each with a total of 30 people who were not randomly selected. The instruments used to collect data were a test of the ability to write procedural texts and a learning independence questionnaire. The results showed that the increase in the ability to write procedural text and the learning independence of students using PBL assisted by serial image media was better than using PBL only. In other words, PBL assisted by serial image media could improve the ability to write procedural texts and the learning independence of students.
Mutual synchronization of spin-torque oscillators consisting of perpendicularly magnetized free layers and in-plane magnetized pinned layers

A mutual synchronization of spin-torque oscillators coupled through current injection is studied theoretically. Models of electrical coupling in parallel and series circuits are proposed. Solving the Landau–Lifshitz–Gilbert equation, excitation of in-phase or antiphase synchronization, depending on the ways the oscillators are connected, is found. It is also found from both analytical and numerical calculations that the current-frequency relations for both parallel and series circuits are the same as that for a single spin-torque oscillator.
Background 2 . 1 Cloud computing : Definition and scope of research

Cloud computing (CC) as an emerging phenomenon promises multiple business-related advantages such as faster time to market, scalability, and lowered barriers to innovation. In order to achieve potential advantages from CC investments, firms must be able to utilize CC resources. Literature suggests that in order to gain advantages from IT, firms are required to possess a bundle of IT capabilities. However, until now it is not clear if these capabilities also apply for CC. Along prior IT capability research and studies on CC, this research, therefore, aims to deductively derive technical, human, and organizational capabilities related to CC. It is argued that these capabilities facilitate organizational CC usage. To test these propositions, quantitative research has been conducted among midsized ICT firms in Germany. The results demonstrate that especially capabilities of the organizational dimension, namely strategic thinking and planning, contribute to CC usage. In contrast, we found no effect of capabilities related to the human dimension (technical integration and sourcing skills of the IT staff) on CC usage. Interestingly, the flexibility of existing IT infrastructure is negatively related to the utilization of CC resources.
Effect of Different Acids, Heating Time and Particle Size on Pectin Extraction from Watermelon Rinds

Watermelon cultivation has widely been expanded in Iraq and industrial by-products like watermelon rinds play an important role in pectin manufacture. The objective of this investigation was to determine a practical follow-up to the extraction of pectin from watermelon rinds and to characterize it in a laboratory, on a small scale, aiming at establishing the optimum conditions for acid extraction. The independent variables were citric acid concentration (0.08 – 5 g/ml) and heating time (20 – 110 min). The highest yields were obtained when watermelon rinds was dried and ground to obtain a watermelon flour to be used as raw material, citric or nitric acids were used and when the citric acid concentration was (5 g/100 ml) and the time of reaction was (110 minutes). The watermelon variety in itself was not significant in pectin yield. The degree of esterification (DE = 44.37 %) of the product obtained, as well as its physical looks, show the success of pectin extraction. Results have shown that the generated model adequately explained the data variation and significantly represented the actual relationship between the independent variables and the responses, with a correlation coefficient of (0.938) and a (44.9454 %) absolute average percent error. : ةصلاخلا تعاُنص ينف مانًاي مارور د نعع هلح تيعاُنص تيضرع جحاوَ يلرنا روشل يف دجوحو قارعنا يف عساو وحَ ىهع يلرنا ثابَ عرزي صلاخخنسلان من فضا فورنرنا رفونح للاخ ٍي ،ربخخًنا يف هخيمُحو يلرنا روشل عٍ ي ٍ يخكبنا صلاخخسلا ثحبنا فداي . ٍ يخكبنا رنيرخًنا ٌ . ين ياحنا يرخنسنا يانت ل زنيارح ينر ع جنَا ل ا تهمخنسًنا ثا . 0 – 5 ىنغ \ ٍيخنسخنا ٍنينو رنخهيهي 0. – 11. :يهي اي اايهع لوصحنا ىح يخنا جئاخُنا ثراظ و . تميلر 1 . واخ ةراًا لاًعخسلااب م فا ع جُ حدطو ع جفّف د ج يخنا يلرنا روشل ٌ 0 . م فضا ور يرخُنا ول يرخسنا يات مًعخس ٌإ . يروهاورديااناو يروفسفناو يخيربكنا ياوحب تَرامي 3 . ل يرخسنا يات ل زيارح ٌوكي ايدُع 5 ىغ \ 100 معافخنا ٍين ٍيخسخنا ٍينو رخهيهي 11. جئاخُنا م فا يطعي تميلر ةرخنسلاا تنجرر جنَاا دنلو . ٍينخكبنا كانخَإ ينف فاُنصضا ٍينب تنيوُعي ثالورف روجو ودع جئاخُنا ثراظ و منصحخسًنا جلخنُ دً هن يننر هننيهع DE = 33.34 كاننخَإ برننح لتننيهعف تيننضاير تننللاع ىنننإ مننصوخنا ىننح اننًا . تننيعيبطنا هننحرارَ ىنننإ تفاننضلإاب ، % كباطخنا مياعي غهب ثيت ،تهمخسًنا ثاريرخًناب ٍ يخكبنا صلاخخسا . 930 ت مهطدً نا أطخنا تبسَ لدعيو
Endophytic mycobiota of wild medicinal plants from New Valley Governorate, Egypt and quantitative assessment of their cell wall degrading enzymes

The present study isolated and identified 32 species of endophytic mycobiota belonging to 18 genera associated with 8 wild medicinal plants collected from El-Kharga Oasis, New Valley Governorate, Egypt. Fusarium was the most common genus followed by Alternaria and Aspergillus. Convolvulus arvensis was the plant with the highest number of endophytes over the other plant species, while Moringa oleifera reported the lowest number of endophytes. In addition, the entomopathogenic fungus Beauveria bassiana; was recorded for the first time from leaves of Portulaca oleracea. One hundred and twenty-three isolates representing 32 species were screened for their abilities to produce pectinase, carboxy methyl cellulase (CMCase) and avicellase enzymes on sucrose free-Cz supplemented, individually with 1% pectin or 1% CMC or 1% avicel as a sole carbon source, respectively. Ninety-four isolates produced pectinase while 66 isolates produced cellulases. The quantitative assays of the three enzymes for high-producers were performed in submerged fermentation using sucrose-free Cz broth. Aspergillus was the superior in the production of the three enzymes with the potent strains were A. terreus AUMC 14287 for CMCase (22.0 IU/ml/min) and avicellase (47.868 IU/ml/min) and A. terreus AUMC 14278 for pectinase (225.43 IU/ml/min). Kew words – cellulose – endophytic fungi – medicinal plants – pectinase – submerged fermentation Introduction Endophytic microorganisms colonize in plant tissues in which they spend part or all their life cycle without causing disease symptoms in the host (Petrini 1991). Fungal endophytes may inhabit in different organs of the host including leaves, stems, bark, roots, fruits, flowers and seeds (Rodriguez et al. 2009). Generally, in this symbiotic relationship fungal endophytes receive shelter and nutrients from the host, while the host plant may benefit from an array of attributes which include protection against natural enemies such as pathogens and herbivores (Schardl et al. 2004, Singh et al. 2011), plant growth promotion (Hamayun et al. 2010) and increasing the resistance of plants to abiotic stresses such as salinity and heavy metal toxicity in soil (Khan et al. 2014). Some medicinal plants are known for harboring endophytic fungi, which are important sources of various Studies in Fungi 6(1): 78–91 (2021) www.studiesinfungi. org ISSN 2465-4973
The equation of state and the quasiparticle mass in the degenerate Fermi system with an effective interaction

General formulas are derived for the quasiparticle effective mass and the equation of state of the Fermi system with account of the interparticle attraction at long distances and repulsion at short distances. Calculations are carried out of the equation of state and the effective mass of the Fermi system at zero temperature with the use of the modified Morse potential. It is shown that the pair repulsive forces promote a decrease of the effective mass, and the attractive forces promote its increase. With a certain choice of the parameters of the potential the dependence of the pressure on the density has a nonmonotonic character, which enables to describe the coexistence of the liquid and gaseous phases. The influence of three-body interactions on the equation of state and the effective mass is considered. The calculation results are compared with experimental data concerning the quasiparticle effective mass in the liquid $^3$He. Key words: normal Fermi liquid, effective mass, quasiparticle, equation of state, interaction potential
Evaluation of the relation between the pulp stones and direct restorations using cone beam computed tomography in a Turkish subpopulation

Objectives This study aimed to assess the presence of pulp stones through an examination of cone beam computed tomography images and correlate their prevalence with age, sex, dental arch and side, tooth type, and restoration type and depth. Materials and Methods Cone beam computed tomography images obtained from 673 patients and archival data on 11,494 teeth were evaluated. The associations of pulp stones with age, sex, dental arch and side, tooth type, and restoration type and depth were noted. All the measurements were subjected to a χ2 test and one sample χ2 test (p < 0.05). Results In the study group, 163 (24.2%) patients and 379 (3.3%) teeth had at least one pulp stone. The pulp stone frequency in those aged 30–39 years was significantly greater than in those aged 18–29 and ≥ 60 years, and the frequency was higher in females than in males (p < 0.05). The highest prevalence of pulp stones was found in maxillary dental arches and molar teeth (p < 0.05). Pulp stones were significantly more common in medium-depth restorations (p < 0.05). Conclusions Maxillary molar teeth, medium-depth restorations, individuals aged 30–39 years and females had a greater percentage of pulp stones.
Does the Role of Media and Founder’s Past Success Mitigate the Problem of Information Asymmetry? Evidence from a UK Crowdfunding Platform

Crowdfunding is an innovative concept for a new start-ups seeking financial support for their distinctive and novel projects. Despite their popularity, crowdfunding platforms face several key challenges amongst which is information asymmetry between entrepreneurs and influential backers, where credible information must be disclosed by the founders (entrepreneurs) to the potential “backers” in order to assess the potentiality of the project. In order to fill this gap, we developed and tested a model that examines the signaling interaction between the founder and a potential backer through media and the founders’ past success. This model also examines how these two signals (i.e., media and past success) interact so as to mitigate the problem of information asymmetry and to make the project successful. A total of 14,887 projects were extracted from a reward-based platform named Crowdfunder. The data was analyzed by performing Tobit and logistic regression and the model was validated by using the robustness technique. The results strongly mitigate the problem of information asymmetry which improves the rate of success in projects floated on the Crowdfunder platform. We believe that our study will significantly contribute to this nascent yet developing research area by probing for information mechanisms to succeed in crowdfunding.
