Formation rate of gravitational structures and the cosmic x-ray background radiation

Analytical expressions for the rates of formation and destruction of gravitationally bound systems are derived assuming that they are originated from primordial random-Gaussian density fluctuations. The resulting formulae reproduce the time derivative of the Press-Schechter mass function in a certain limit. Combining a theoretical model for the evolution of structures with the formation rate, we can make various cosmological predictions which are to be compared with observations. As an example to elucidate such applicability, we evaluate the contribution of clusters of galaxies to the cosmic X-ray background radiation. With the {\it COBE} normalization, we find that the significant fraction of the observed soft X-ray background is accounted for by clusters of galaxies in a cold dark matter universe with $\Omega_0 \sim 0.2$, $\lambda_0 =1- \Omega_0$ and $h \sim 0.8$.
Investigación sobre el conteo infantil

Aunque la visión tradicional sobre esta cuestión situaba en algún momento entre los 6 y los 7 años la divisoria entre el conocimiento numérico con verdadero fundamento matemático y la simple utilización rutinaria de las palabras-número, lo cierto es que en los últimos tiempos están apareciendo datos que sugieren con insistencia que las habilidades numéricas de niños menores de 6 años y que, incluso, la formas de representación no-verbal de los números son fenómenos cognitivos que deben tenerse muy en cuenta (Feigenson et al., 2006; Clark y Grossman, 2007; Kobayashi et al., 2004; Xu y Arriaga, 2007; Xu, et al., 2005).
Linkage Mapping Reveals QTL for Flowering Time-Related Traits under Multiple Abiotic Stress Conditions in Maize

Variation in flowering plays a major role in maize photoperiod adaptation during long-term domestication. It is of high value to investigate the genetic basis of maize flowering under a wide range of environmental conditions in order to overcome photoperiod sensitivity or enhance stress tolerance. A recombinant inbred line (RIL) population derived from a cross between Huangzaosi and Mo17, composed of 121 lines and genotyped by 8329 specifically developed markers, was field evaluated in two consecutive years under two planting densities (67,500 and 120,000 plants ha−1) and two water treatments (normal irrigation and drought stress at the flowering stage). The days to silking (DTS), days to anthesis (DTA), and anthesis to silking interval (ASI) were all evaluated. Within the RIL population, DTS and DTA expanded as planting density and water deficit increased. For DTA, DTS, ASI, and ASI-delay, a total of 22, 17, 21, and 11 QTLs were identified, respectively. More than two significant QTLs were identified in each of the nine chromosomal intervals. Under diverse conditions and locations, six QTLs (quantitative trait locus) for DTS and DTA were discovered in Chr. 8: 118.13–125.31 Mb. Three chromosome regions, Chr. 3: 196.14–199.89 Mb, Chr. 8: 169.02–172.46 Mb, and Chr. 9: 128.12–137.26 Mb, all had QTLs for ASI-delay under normal and stress conditions, suggesting their possible roles in stress tolerance enhancement. These QTL hotspots will promote early-maturing or multiple abiotic stress-tolerant maize breeding, as well as shed light on the development of maize varieties with a broad range of adaptations.
“The Pokémon that Got Away”: Employing Actor-Network Theory “The Pokémon that Got Away”: Employing Actor-Network Theory to Unmask the Technology Actor in Cybernized Services to Unmask the Technology Actor in Cybernized Services

Digitalization and emerging technologies have given rise to cybernized services and a debate questioning the traditional Service-dominant logic (SDL) view of technology as a resource in service exchange. To date, little is known on the role of technology as a value co-creating (or co-destroying) actor in the context of services empowered by emerging technologies. Attaining an in-depth understanding of technology as an actor in cybernized service ecosystems is integral for practitioners and researchers alike to foster and investigate value co-creation in the sociotechnical interactions from the perspective of the involved human actors. To address this need, we unmask the technology actor by conducting a qualitative content analysis on in-depth laddering interviews with users of the Augmented Reality (AR) mobile game application Pokémon Go. Employing the Actor-Network Theory (ANT), we depict three emerging technology actor roles in service exchange and discuss their value co-creative/destructive implications to research and practice.
The Uncertainty-based Retrieval Framework for Ancient Chinese CWS and POS

Automatic analysis for modern Chinese has greatly improved the accuracy of text mining in related fields, but the study of ancient Chinese is still relatively rare. Ancient text division and lexical annotation are important parts of classical literature comprehension, and previous studies have tried to construct auxiliary dictionary and other fused knowledge to improve the performance. In this paper, we propose a framework for ancient Chinese Word Segmentation and Part-of-Speech Tagging that makes a twofold effort: on the one hand, we try to capture the wordhood semantics; on the other hand, we re-predict the uncertain samples of baseline model by introducing external knowledge. The performance of our architecture outperforms pre-trained BERT with CRF and existing tools such as Jiayan.
Inhibition of MCT1 to Reduce Tumor Invasion During Early Malignant Progression in HNSCC

: Head and neck squamous cell carcinoma (HNSCC) is a widespread and common cancer, ranking as the sixth most prevalent form of cancer within the last decade. Treatment resistance and tumor persistence are large contributing factors to the mortality of HNSCC. One mechanism of treatment resistance is the maintenance of stem cell-like properties of cancer cells and their subsequent adaptability to changes in the tumor microenvironment (TME). Monocarboxylate transporter-1 (MCT1) is an important transport protein that aids in cancer cell invasion, supports cell growth, and improves cell adaptivity in the TME through transport of important monocarboxylates. This study aimed to inhibit MCT1 both genetically through CRISPR/Cas9 gene editing and pharmacologically through use of AZD3965, an MCT1 inhibitor, in order to measure the effect of cancer cell invasion and determine if MCT1 can be a therapeutic target for HNSCC. Genetic knockout of MCT1 led to substantial decreases in invasion of an HNSCC cell line; pharmacological inhibition of MCT1 also decreased invasion, though not significantly. These findings suggest that MCT1 plays a major role in the invasion of HNSCC cells and targeting this protein may provide novel solutions to treating resistant HNSCC.
A Novel Analytical Approach for Time - response shaping of the PI controller in Field Oriented Control of the Permanent Magnet Synchronous Motors

Background and Objectives: Permanent magnet synchronous motors (PMSM) have received much attention due to their high torque as well as low noise values. However, several PI blocks are needed for field, torque, and speed control of the PMSM which complicates controller design in the vector control approach. To cope with these issues, a novel analytical approach for time-response shaping of the Pi controller in the filed oriented control (FOC) of the PMSM is presented in this manuscript. In the proposed method, it is possible to design the controlling loops based on the pre-defined dynamic responses of the motor speed and currents in dq axis. It should be noted that as decoupled model of the motor is employed in the controller development, a closed loop system has a linear model and hence, designed PI controllers are able to stabilize the PMSM in a wide range of operation. Methods: To design the controllers and choose PI gains, characteristic of the closed loop response is formulated analytically. According to pre-defined dynamic responses of the motor speed and currents in dq-axis e.g., desired maximum overshoot and rise-time values, gains of the controllers are calculated analytically. As extracted equation set of the controller tuning includes a nonlinear term, the Newton-Raphson numerical approach is employed for calculation of the nonlinear equation set. In addition, designed system is evaluated under different tests, such as step changes of the references. Finally, it should be noted that as the decoupled models are employed for the PMSM system, hence exact closed loop behavior of the closed loop system can be expressed via a linear model. As a result, stability of the proposed approach can be guaranteed in the whole operational range of the system. Results : Controlling loops of the closed loop system are designed for speed control of the PMSM. To evaluate accuracy and effectiveness of the controllers, it has been simulated using MATLAB/Simulink software. Moreover, the TMS320F28335 digital signal processor (DSP) from Texas Instruments is used for experimental investigation of the controllers. Conclusion: Considering the simulation and practical results, it is shown that the proposed analytical approach is able to select the controlling gains with negligible error. It has shown that the proposed approach for rise time and overshoot calculations has at most 0.01% for step response of the motor speed at 500 rpm.
Microwave Energy in Controlling Warehouse Insects (Sitophilus oryzae L) and Determining the Percentage of Killing on the Unit Weight of Wheat Seeds

Sitophilus oryzae L (Coleoptera) is a primary pest of stored grains in many regions of the world. This research paper aims to use non-traditional methods to control some insects on stored grain. The use of insecticides and their side effects on health and the environment, in general, are proven Pest control should take another direction. Wheat samples were taken with different weights of 10,20,40,60,80,100,200 g for three separate packages, and (30) insects of Sitophilus oryzae L were added to each sample and were mixed randomly. , 5, 10,15,20,25 ‘30’ seconds to calculate the time on the amount of weight of treated seeds to give the best results weight 10 g, microwave treatment, time of 20 seconds, the killing rate was 100%, and 15 seconds was 90%. Weight 20g Microwave treatment for 25 seconds (100 percent kill rate) and 20 seconds (92.30 percent kill rate) for optimal results. Weight 40g Microwave treatment for 20 seconds (100 percent kill rate) and 15 seconds (76.10 percent kill rate) for optimal results. Microwave 60g for 25 seconds for a 100% kill rate and 20 seconds for an 88 percent kill rate for optimal outcomes. Microwave 80g for 25 seconds for a 100% kill rate and 20 seconds for an 86.60 percent kill rate for optimal outcomes. For optimal results, microwave 100g for 30 seconds for a 100% kill rate and 25 seconds for a 99.80% kill rate. Microwave 200g for 35 seconds for a 100% kill rate and 30 seconds for a 99.60% kill rate for optimal outcomes. From this, we can deduce that the time needed to kill all insects in the sample preparation for testing must be doubled for every 20 g of wheat seeds added.

Environmental Pollution Caused by Heavy Metals and Radioactivity in Two Governorates in Iraq

This study focused on knowing the levels of pollution caused by heavy metals (iron, lead) and gamma rays in the governorates of Maysan and Basra. The highest value of gamma rays was in Maysan governorate, there is a rise in these rates, according to the comparison conducted with international research, but these values do not represent a significant danger. The samples in this study are normal and free of pollution. It was found that the highest value of gamma rays in Maysan is 0.7 μSv/h at S5 and S9. The lowest value was 0.11 μSv/h in S3. As for the heavy elements, the highest value of iron was found at 0.2811 mg/l in Karama village (S2), and the lowest value was 0.2203 mg/l in S3 and the highest value for lead was 0.2632 mg/l in Kameet and the lowest value was 0.0033 In the village of Al-Huda, the highest value of gamma rays was observed at 0.8 uSv/h in S6 and S7, and the lowest value was 0.11 μSv/h in S2. The highest value for iron Fe was 0.3452 mg/l at the site S4 Al-Burjisiya Road 17, and the lowest value was 0.2232/ml for S9 Safwan Street, while pb had the highest value of 0.2817 mg/L in S7 of Zubair farms, and the lowest value was 0.0319 mm/L in S9 of Safwan Street.
Body Condition Score and Its Association with Productive and Reproductive Performance and Health Status in Dairy Cattle: Review Article

Body condition score is a well pointer of cows energy reserves during the lactation season and can be a good measure of cows that are capable of balance well between milk production and feed intake. From a review of researches, it was found the importance of determining the body condition score in the management of dairy cows, as it is related to milk production, reproductive performance and health status, as the over or excessive and low body condition score has a negative impact on the general performance of dairy cows. Thus, measuring the body condition may be an essential instrument in the management of cows to increase milk production, improve reproductive performance and reduce the incidence of health problems.
Cardiovascular magnetic resonance characteristics and clinical outcomes of patients with ST-elevation myocardial infarction and no standard modifiable risk factors–A DANAMI-3 substudy

Introduction A higher 30-day mortality has been observed in patients with first-presentation ST elevation myocardial infarction (STEMI) who have no standard modifiable cardiovascular risk factors (SMuRFs), i. e. , diabetes, hypertension, hyperlipidemia, and current smoker. In this study, we evaluate the clinical outcomes and CMR imaging characteristics of patients with and without SMuRFs who presented with first-presentation STEMI. Methods Patients from the Third DANish Study of Acute Treatment of Patients With ST-Segment Elevation Myocardial Infarction (DANAMI-3) with first-presentation STEMI were classified into those with no SMuRFs vs. those with at least one SMuRF. Results We identified 2,046 patients; 283 (14%) SMuRFless and 1,763 (86%) had >0 SMuRF. SMuRFless patients were older (66 vs. 61 years, p < 0.001) with more males (84 vs. 74%, p < 0.001), more likely to have left anterior descending artery (LAD) as the culprit artery (50 vs. 42%, p = 0.009), and poor pre-PCI (percutaneous coronary intervention) TIMI (thrombolysis in myocardial infarction) flow ≤1 (78 vs. 64%; p < 0.001). There was no difference in all-cause mortality, non-fatal reinfarction, or hospitalization for heart failure at 30 days or at long-term follow-up. CMR imaging was performed on 726 patients. SMuRFless patients had larger acute infarct size (17 vs. 13%, p = 0.04) and a smaller myocardial salvage index (42 vs. 50%, p = 0.02). These differences were attenuated when the higher LAD predominance and/or TIMI 0-1 flow were included in the model. Conclusion Despite no difference in 30-day mortality, SMuRFless patients had a larger infarct size and a smaller myocardial salvage index following first-presentation STEMI. This association was mediated by a larger proportion of LAD culprits and poor TIMI flow pre-PCI.

Predictors of thromboembolic complications after stent-assisted coiling of acutely ruptured intracranial aneurysms: A retrospective multicenter study

Background Stent-assisted coiling (SAC) has been reported to safely and effectively treat wide-necked unruptured intracranial aneurysms. However, SAC of acutely ruptured aneurysms is controversial because of perioperative thromboembolic complications. We aimed to investigate the predictors of the thromboembolic complications after SAC of acutely ruptured aneurysms. Methods We performed a retrospective multicenter analysis of 110 consecutive patients with ruptured intracranial aneurysms treated with SAC within 72 h of the onset of subarachnoid hemorrhage. Thromboembolic complications were defined as any angiographic filling defects at the aneurysms base or the distal artery during the stent treatment and the new onset of symptomatic ischemia and a new hypo-density in a vascular distribution confirmed by CT scan within 24 h of treatment. These patients were grouped into patients with thromboembolic complications and those without thromboembolic complications. A multivariate logistic regression analysis was performed to identify predictors of thromboembolic complications. Results One hundred and one patients with 101 ruptured aneurysms were included in this study. 9 (8.9%) patients experienced thromboembolic complications. Patients with thromboembolic complications had a higher rate of unfavorable outcomes at discharge (P < 0.001) and at the last follow-up (p = 0.017). Of these patients, four patients presented with intraprocedural thrombus formation, and 5 experienced postprocedural ischemia. There was a trend toward thromboembolic complications in patients with a higher Fisher grade (p = 0.076) and those treated with intravenous tirofiban (p = 0.052). Patients with thromboembolic complications more often presented with poor grade clinical conditions (p = 0.005) and aneurysms with a large dome to neck ratio (p = 0.031). In the multivariate analysis, a worse World Federation World Federation of Neurological Societies (WFNS) grade (OR = 8.241; 95% CI 1.686–40.292; P = 0.009) and a larger dome to neck ratio (OR = 5.385; 95% CI 1.023–28.337; P = 0.047) were independent predictors of thromboembolic complications. Conclusion Patients with thromboembolic complications are more likely to have an unfavorable outcome. A worse clinical condition before the treatment and a larger dome to neck ratio were independent predictors of thromboembolic complications after SAC of acutely ruptured intracranial aneurysms.
Anisotropic wet etching on the β -phase poly(vinylidene ﬂ uoride) ﬁ lm

The ability to fabricate micro patterns or micro structures directly on a ﬂ exible and piezoelectric β -phase poly(vinylidene ﬂ uoride) (PVDF) ﬁ lm, has potential applications in the ﬁ eld of micro-electro-mechanical systems. The authors realised several tens to several hundred of micro patterns directly on a 110- μ m thick ﬂ exible β -phase PVDF ﬁ lm by wet-etching technology. Through experiments, the authors also found that the β -phase PVDF ﬁ lm shows anisotropic etching characteristic in the proposed wet-etching process. In this Letter, the authors reported β -phase PVDF ﬁ lm micropattern fabrication process and its anisotropic wet-etching properties for the ﬁ rst time.
Human Active Learning

Active machine learning (AML) is a popular research area in machine learning. It allows selection of the most informative instances in training data of the domain for manual labeling. AML aims to produce a highly accurate classifier using as few labeled instances as possible, thereby minimizing the cost of obtaining labeled data. As machines can learn from experience like humans do, using AML for human category learning may help human learning become more efficient and hence reduce the cost of teaching. This chapter is a review of recent research literature concerning the use of AML technique to enhance human learning and teaching. There are a few studies on the applications of AML to the human category learning domain. The most interesting study was by Castro et al., which showed that humans learn faster with better perfor mance when they can actively select the informative instances from a pool of unlabeled data instead of random sampling. Although AML can facilitate object categorization for humans, there are still many challenges and questions that need to be addressed in the use of AML for modeling human categorization. In this chapter, we will discuss some of these challenges.
ROLE OF MODERN DIAGNOSTIC IMAGING MODULATES IN DIAGNOSING ACUTE APPENDICITIS IN PREGNANT PATIENTS

: Introduction Acute appendicitis is not a rare condition in pregnant patients. it accounts for 1 in 500-635 pregnancies per year. Diagnostic Imaging in pregnancy is of higher significance. Aims and Objectives: The main aim and objectives of this study are to analyze all diagnostic imaging modalities. Diagnosis of Acute Appendicitis: The most typical symptoms are acute right lower quadrant (RLQ) abdominal pain, relocation of pain from an upper part of the abdomen to the RLQ, loss of appetite, nausea, vomiting, and elevation of temperature. Imaging Techniques: Today, imaging for suspected appendicitis is even considered mandatory in many institutions. Major imaging modalities utilized to diagnose acute appendicitis in pregnant patients is US and MRI. Effects of Radiations: The precise risks of radiation from diagnostic imaging are unknown, but estimations based on research exist. Discussion : US persists as the first line of imaging, as a rule, yet of coarse accuracy and other imaging tools such as CT or MRI are usually avoided for the diagnosis of acute appendicitis in pregnant patients. Conclusion : literature review suggested that the imaging of choice for acute appendicitis is US. Now MRI is also recommended as a first-line diagnostic test. CT will only be performed only as a last resort.
behavioral assessment of metrics in manet routing protocols under realistic environments

A Network in which nodes communicate without any centralized control or infrastructure can be considered as Mobile Ad-hoc Network (MANET.). Data is exchanged in multi hops via wireless channels . For the smooth exchange of information, we need routing protocols for effective and timely delivery of the message. Ad hoc routing protocols AODV, DSDV, DSR, TORA have several metrics like Throughput, End to End Delay Normalized Route Load, Packet Delivery Ratio, Energy Efficiency, the number of nodes, fidelity, distance, etc., to Asses. We have compared routing protocols basing on these metrics and the performance is analyzed and graphs have been generated on Network Simulator (NS-2, NS-3).
