Lung Disease Detection Using CNN

Covid Pneumonia is a life-threatening bacterial disease in humans that affects one or both lungs and is caused by the bacteria Streptococcus pneumonia. Also known as Covid-19, this is a respiratory illness that was first discovered in Wuhan, China. Expert radiotherapists must evaluate chest X-rays used to diagnose pneumonia. As a result, establishing an autonomous system for detecting pneumonia would be advantageous for treating the condition quickly, especially in distant places. The statistical results show that using pre trained CNN models and supervised classifier algorithms to analyse chest X-ray pictures, specifically to diagnose Pneumonia, can be highly advantageous. By constructing certain convolution neural network designs, we are developing a classifier model that accurately predicts if a person has covid or pneumonia.
Laryngeal height and voice characteristics in children with autism
 spectrum disorders*

The purpose of this study was to investigate laryngeal characteristics in children with autism spectrum disorders (ASD). A total of 50 children participated, including eight children aged 2 to 4 years old diagnosed with ASD and 42 normal controls at the same age. All children recorded X-ray images of the midsagittal plane of the cervical spine and larynx, and compared the laryngeal positions of ASD and control. In addition, samples of children with vowel prolongation were collected and analyzed for acoustic parameters. X-rays showed that the height of the hyoid bone in the normal group was the lowest at 3 years of age, and ascended at 4 years of age. Nevertheless, the distance from the external acoustic meatus to the hyoid bone was longest at age 4. 4-year-olds with explosive language development showed laryngeal height elevation and anteriorization. In contrast, the hyoid height of the ASD group of all ages was lower than that of the control group, and there was no difference in the hyoid position between the ages. As a result of acoustic evaluation, PFR, vFo, and vAm were significantly higher ASD than control. Low laryngeal height of ASD children may be associated with delayed language development. PFR, vFo, and vAm seem to be voice markers showing the difference between normal and ASD children.
Evidence for a Locally Thinned Lithosphere Associated With Recent Volcanism at Aramaiti Corona, Venus

Heat flow estimates of terrestrial planets and icy satellites are important for exploring their thermal evolution. Topographic signatures of flexure can be used to estimate the effective elastic lithospheric thickness, he, and heat flow. Here, we use high resolution stereo topography and axisymmetric elastic flexure models to investigate lithospheric flexure around Narina Tholus, a steep‐sided volcanic dome ∼40 km across that superposes the tectonic annulus of Aramaiti Corona. Our results indicate a best‐fit elastic thickness he = 3.9–9.1 km, for values of Young's modulus, E, ranging from 65 to 5 GPa respectively. This suggests a thinned lithosphere locally around Narina Tholus, compared to regional estimates for he. The lower values of E are appropriate to the heavily fractured environment of the corona annulus, and we find that they predict flexural stresses compatible with the limited fracturing observed around Narina Tholus. A global survey yielded 13 additional tholi (or tholi groups) at coronae and with stereo coverage, none of which showed evidence for flexure. We find, that locally at Narina Tholus, the heat flow is elevated by a factor of 2–4 relative to that inferred from a previous study of flexure at Aramaiti, consistent with late‐stage, possibly recent, volcanism focused at, and facilitated by, the fracture annulus. Our results further strengthen arguments for a currently volcanically active planet and demonstrate the role that high‐resolution stereo topography can play in elucidating the current thermal state of Venus.

Impact of combined xylanase and β-glucanase enzymes on digesta transit time, short-chain fatty acids, and caecal thermal profile of broilers fed corn–soy-based diets

Abstract: A study was conducted to evaluate the effects of including a xylanase + β-glucanase enzyme product in corn–soy-based diets on performance, caecal short-chain fatty acids and thermal profile, ileal digestibility, and intestinal kinetics of broiler chickens. A total of 744 male day-old chicks were randomly allotted to 24 floor pens and distributed in a 2 × 2 factorial arrangement with low or standard energy level × without or with 100 g of the enzyme per ton of feed. Enzyme supplementation improved bodyweight gain from 1 to 21 d (P < 0.05). An increased caecal concentration of acetic acid was observed when the enzyme was added to the low-energy diet (P < 0.05). The pH of the caecal content was reduced (P < 0.01), and the caecal temperature was increased by low-energy diets (P < 0.05). The apparent ileal digestibility of energy was improved by the enzyme (P < 0.01). The addition of the enzyme increased the mean retention time in the distal ileum (P < 0.05). In summary, the addition of a xylanase + β-glucanase enzyme product in corn-based diets increases the retention time of digesta in the distal ileum and the caecal acetic acid concentration, improves ileal digestibility of energy and performance from 1 to 21 d in broiler chickens fed corn–soy-based diets.
Research on the multi-channel operation of MAC protocol in wireless sensor networks

This paper briefly introduced Wireless Sensor Network (WSN) and the competitive Medium Access Control (MAC) protocol for assisting the multi-channel operation in WSN. Then, the avoidance operation of the traditional competitive MAC protocol was improved. The WSN that adopted two MAC protocols was simulated in the MATLAB software, and the performance of WSN under different node number was tested. The results showed that the WSN that adopted the traditional MAC protocol had decreased throughput and channel utilization and increased average time delay with the increase of node number in the WSN; the WSN that adopted the improved MAC protocol had decreased throughput and relatively stable average time delay and channel utilization with the increase of node number in the WSN; under the same number of nodes, the WSN that adopted the improved MAC protocol had higher throughput and channel utilization and lower average time delay.

The findings of this study revealed that reading comprehension is the ability of the students to analyze, decode, integrate prior knowledge, interpret and clearly understand the words, sentence, or compositions particularly the content and its contexts. The different strategies used in teaching reading comprehension as well as different strategies that can be used during the modular learning approach were presented. The emphasis on modular distance learning was found that it can be used as an alternative learning approach that uses self-learning modules. It was also revealed that both internal and external factors have influence students reading comprehension difficulties amidst the use of modular distance learning approach. Students’ perception on reading comprehension difficulty level during modular distance learning approach is difficult. There is no significant difference on students’ reading comprehension difficulty level amidst the use of modular distance learning approach as perceived by the students that resulted to the acceptance of the null hypothesis. The study recommended that the school administrators should initiate trainings, seminars and workshops about different strategies that is timely to help their faculty members improve the reading comprehension of the students. The school administrators should also supervise their teachers to use strategies that are appropriate and applicable on the type of learning style they are using. The teachers should use strategies and learning resources that suits the kind of learners and the type of learning style they have. The teachers should also exert extra effort in facilitating the students’ learning even in the absence of face-to-face interaction. The parents should guide and monitor their children’s learning at home.
Antioxidant and antibacterial activities of 13 ornamental herbaceous peony cultivars: a comparative study with stems and leaves

ABSTRACT Paeonia lactiflora is an important ornamental and medicinal plant, but after the flowering period, the above-ground parts of ornamental cultivars are often discarded as waste. When considering the development of medicinal plant resources, attention should be paid to the comprehensive development and utilisation of the plant. In this study, 13 ornamental herbaceous peony cultivars were selected, and their stems and leaves were analysed for antioxidant and antibacterial activities. The results showed that total phenolic content (TPC), total flavonoid content (TFC), antioxidant activity and antibacterial activity varied depending on the cultivar and plant organ. In the same cultivar, the TPC and TFC of leaves were higher than those of the stems. The antioxidant activity was significantly correlated with TPC of stems and leaves. In the antibacterial assay, the extracts of stem and leaves of the cultivars ‘Hong Yan Fei Shuang’ and ‘Chun Xiao’ were the most effective against most of the tested strains. This is an innovative study that shows the great potential of ornamental herbaceous peony stems and leaves as sources of biologically active compounds.
How to Effectively Design Referral Rewards to Increase the Referral Likelihood for Green Products

Interpersonal referrals can effectively promote purchases. In view of the low sales of green products, this study introduces the referral reward program into green marketing and investigates the impact of reward type on customers’ referral likelihood for green product. Through a lab experiment with 302 participants in China involved, this study reveals the differential effects of monetary versus donation rewards on existing customers’ referral likelihood. Specifically, compared with monetary rewards, donation rewards are more effective in promoting recommendations. It is also indicated that the perceived fit between the reward and green products partially mediates the relationship between the reward type and referral likelihood. In addition, the relationship between the reward type and perceived fit is moderated by consumers’ green product knowledge. This research not only extends the literature on green marketing and referral reward programs, but also provides feasible suggestions for government and enterprises to promote green products and to improve social wellbeing.
Maternal Nutrition Status and Human Milk Composition of DHA and AA Fatty Acids in Breastfeeding Honduran Women

Dietary habits and maternal nutrition status are the most important modifiable factors that will determine the concentration of certain essential components and nutrients in Breast Milk (BM). The objectives were to estimate the nutritional status of Breastfeeding (BF) women in rural Honduras, identifying the main food sources that contribute to the consumption of EFA and its content in BM. The Honduran study was part of an international study with a sample (n=25) with children between 26 and 64 days of age. The consumption of food sources of Essential Fatty Acids (EFA) was evaluated with a frequency questionnaire. BMcomposition was analyzed using the dry drop method with Guthrie cards. 56% of mothers provided exclusive BF, 27% of mothers were overweightand 68% had excess body fat. The average monthly consumptionof marine foods was 1.44, 0.60 and 0.68 servings of fish, sardines and tuna, respectively. The average consumption of Docosahexaenoic Acid (DHA) and Arachidonic Acid (AA) was 0.05 g / day. The content of DHA, EPA and AA fatty acids in BM was 0.14, 0.01 and 0.4% respectively. The amount of DHA and AA in the BF women is well below the median values of a global reference distribution.
The Investigations of Atrial Fibrillation Burden after Cryoballoon Ablation Detected by Insertable Cardiac Monitor in Patients with Paroxysmal Atrial Fibrillation: A Study Protocol for a Multicenter Randomized Controlled Trial (Cryo-ICM AF study)

Background: With the increasing number of aged population in China, the mortality and disability caused by atrial fibrillation (AF) and its complications lead to serious social burden and becoming more prominent. Due to the high false-negative rates of AF detected by routine ECG, the results on the recurrent rate and AF burden after cryoballoon ablation (CBA) in real world are inconsistent so far. Since the extension of monitoring time, the increased detection of AF in patients, insertable cardiac monitor (ICM) has its unique merits.

A Data-Driven Feature Based Learning Application to Detect Freeway Segment Traffic Status Using Mobile Phone Data

With the finishing of the construction of the main body of a freeway network, adequately monitoring the traffic status of the network has become an urgent need for both travelers and transportation operators. Various methods are proposed to collect traffic information for this purpose. In this article, a data-driven feature-based learning application is implemented to detect segment traffic status using mobile phone data, building on the practical success of deep learning models in other fields. The traffic status estimation is achieved via the application of a three-level long, short-term memory model. Two phone features are extracted from the raw mobile phone data. A large-scale field experiment was conducted using actual data in Jiangsu, China collected over the “National Holiday Golden Week” of 2014. To evaluate the performance, both precision and recall scores are given along with the overall accuracy. The final results of the large-scale experiment indicate that the proposed application performed well and can be an emerging solution for traffic state monitoring when only limited roadside sensing devices are installed.
A Concise Review on Interlayer Bond Strength in 3D Concrete Printing

Interlayer bond strength is one of the key aspects of 3D concrete printing. It is a well-established fact that, similar to other 3D printing process material designs, process parameters and printing environment can significantly affect the bond strength between layers of 3D printed concrete. The first section of this review paper highlights the importance of bond strength, which can affect the mechanical and durability properties of 3D printed structures. The next section summarizes all the testing and bond strength measurement methods adopted in the literature, including mechanical and microstructure characterization. Finally, the last two sections focus on the influence of critical parameters on bond strength and different strategies employed in the literature for improving the strength via strengthening mechanical interlocking in the layers and tailoring surface as well as interface reactions. This concise review work will provide a holistic perspective on the current state of the art of interlayer bond strength in 3D concrete printing process.
A Novel Auxiliary Resonant Commutated Pole Soft-switching Inverter

In order to reduce the number of auxiliary inductors and improve the load adaptability of the auxiliary resonant commutation pole soft-switching inverter(ARCP) inverter, a novel auxiliary resonant commutation pole soft-switching inverter is proposed, which is characterized by simple structure and low power loss. The proposed inverter only contains two auxiliary commutation inductors. And the commutation processes of the two-phase main switches are simultaneously assisted by the same auxiliary inductor. All main switches in the proposed inverter can achieve zero voltage switching, and all auxiliary switches can achieve zero current switching. The proposed inverter has a simpler structure, higher efficiency and better load adaptability than the ARCP inverter. The effectiveness of the proposed inverter is verified by simulation and the experiment results.
Discovery and Functional Interrogation of the Virus and Host RNA Interactome of SARS-Cov-2 Proteins

The COVID-19 pandemic was caused by severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2). Here, we use enhanced crosslinking and immunoprecipitation to investigate SARS-CoV-2 protein interactions with viral and host RNAs. SARS-CoV-2 proteins, NSP8 and NSP12, bind to specific regions in the RNA viral genome, providing evidence for their central and potential roles in replication, transcription and genome recombination. SARS-CoV-2 proteins expressed in human lung epithelial cells bind to 4,821 unique host RNAs. Nine SARS-CoV-2 proteins upregulate target gene expression, including NSP12 which upregulates mitochondrial and N-linked glycosylation proteins. Furthermore, siRNA knockdown of host genes targeted by the viral proteins in human lung organoid cells demonstrates substantial antiviral effects. Conversely, NSP9 inhibits host gene expression by blocking mRNA export and dampens inflammatory responses such as interleukin-1α/β production. Our extensive viral protein-RNA interactome provides a catalog of potential therapeutic targets and offers insight into the etiology of COVID-19 as a safeguard against future pandemics.
