A negative decrement in geomagnetic data in equatorial region is not necessarily cause by the well-known counter electrojet, CEJ but it is also can be affected by solar activity such as a solar flare. Relying on this matter, we did a comparison between CEJ and unusual solar flare effect called as SFE* on geomagnetic data before introducing several types of CEJ that can be extracted from EUEL index. This study used ground data from MAGDAS network located in Langkawi (LKW) with 1-minutes resolution during solar cycle 24 and applied EUEL index. From the results, it is crucial to ensure the minimum duration of EUEL depletion is within an hour because less than an hour depletion could be possibly cause by solar activity. Four interval of time that has been introduced in our study composed of several types of CEJ which are morning CEJ, afternoon CEJ and evening CEJ, with additional the controversial CEJ occurrence which is night CEJ. We also successfully demonstrated a rare CEJ occurrence that associated with solar flare effect using EUEL index.

Senescence is the gradual process of aging in tissues and cells, and a primary cause of aging-associated diseases. Among them, intestinal stem cells (ISCs) experience exhaustion during aging, leading to reduced regenerative capacity in the intestinal crypt, which impairs intestinal function and contributes to systemic health issues. Given the critical role ISCs play in maintaining intestinal homeostasis, preventing their senescence is essential for preserving intestinal function. Among the various strategies proposed to slow cellular senescence, regular exercise has emerged as one of the most well-known and widely accepted interventions. Here, we examined how exercise affects the small intestine in an aging mouse model. Using single-cell RNA sequencing, we found that signaling pathways and gene expression related to DNA replication and cell cycle progression were upregulated in ISCs. Additionally, genes promoting ribosome biogenesis showed increased expression in both ISCs and transit amplifying cells. Exercise also recovered Wnt signaling inhibition, potentially influencing ISC differentiation. Furthermore, exercise increased Reg3g expression in Paneth cells and improved gut barrier function, contrasting with findings from a diet-induced obese mouse model. This suggests that regular exercise helps inhibit the aging of ISCs in multiple ways, contributing to the maintenance of intestinal homeostasis.

The use of computer-aided diagnosis in the reliable and fast detection of corona virus disease (COVID-19) has become a necessity to prevent the spread of the virus during the pandemic to ease the burden on the medical infrastructure. Chest X-ray (CXR) imaging has several advantages over other imaging techniques as it is cheap, easily accessible, fast and portable. CXR images are sometimes of poor quality and so image enhancement techniques can help the machine learning models to extract valuable discriminating features from the image. Numerous works have been reported on COVID-19 detection from smaller set of original X-ray images. However, the effect of image enhancement in COVID-19 detection was not reported in the literature. This paper explores the effect of various popular image enhancement techniques and states the © 2020, CC BY.

Business Model Canvas (BMC) is a tool widely used to describe startup business models. Despite the various business aspects described, BMC pays a little emphasis on team- related factors. The importance of team-related factors in software development has been acknowledged widely in literature. While not as extensively studied, the importance of teams in software startups is also known in both literature and among practitioners. In this paper, we propose potential changes to BMC to have the tool better reflect the importance of the team, especially in a software startup environment. Based on a literature review, we identify various components related to the team, which we then further support with empirical data. We do so by means of a qualitative case study of five startups.

Predicting online item-choice behavior: A shape-restricted regression approach

This paper examines the relationship between user pageview (PV) histories and their item-choice behavior on an e-commerce website. We focus on PV sequences, which represent time series of the number of PVs for each user-item pair. We propose a shape-restricted optimization model that accurately estimates item-choice probabilities for all possible PV sequences. This model imposes monotonicity constraints on item-choice probabilities by exploiting partial orders for PV sequences, according to the recency and frequency of a user's previous PVs. To improve the computational efficiency of our optimization model, we devise efficient algorithms for eliminating all redundant constraints according to the transitivity of the partial orders. Experimental results using real-world clickstream data demonstrate that our method achieves higher prediction performance than that of a state-of-the-art optimization model and common machine learning methods.

In this study distillery wastewater was treated using the vermifiltration technology in a bid to reduce downstream contamination by the effluent. 10 kg of Eisenia fetida earthworms were used as the vermifiltration media in a 0.5 m × 0.5 m x 0.3 m vermifiltration bed over a 40 h period cycle. The distillery effluent physicochemical parameters which included pH, total Kjeldahl nitrogen (TKN), biological oxygen demand (BOD), total dissolved solids (TDS), total suspended solids (TSS) and the chemical oxygen demand (COD) were measured every 5 days. The vermicompost which was produced as a result of the vermifiltration process's nitrogen, phosphorous and potassium composition was also determined. The distillery effluent pH changed from acidic to neutral whilst a decrease of 94.9% was observed for the TKN, 91.1% for the BOD, 91.9% for the TDS, 92.4% for the TSS and 89.4% for the COD upon treatment with vermifiltration. The vermicompost, a by-product of the vermifiltration process had a nitrogen, phosphorous and potassium composition of 1.87%, 0.87% and 0.66% respectively. © 2018 The Authors

State-space network topology identification from partial observations

作者： Coutino, Mario Isufi, Elvin Maehara, Takanori Leus, Geert faculty of Electrical Engineering Mathematics and Computer Science Delft University of Technology Delft Netherlands Department of Electrical and Systems Engineering University of Pennsylvania Philadelphia United States AIP RIKEN Tokyo Japan

In this work, we explore the state-space formulation of a network process to recover, from partial observations, the underlying network topology that drives its dynamics. To do so, we employ subspace techniques borrowed from system identification literature and extend them to the network topology identification problem. This approach provides a unified view of the traditional network control theory and signal processing on graphs. In addition, it provides theoretical guarantees for the recovery of the topological structure of a deterministic continuous-time linear dynamical system from input-output observations even though the input and state interaction networks might be different. The derived mathematical analysis is accompanied by an algorithm for identifying, from data, a network topology consistent with the dynamics of the system and conforms to the prior information about the underlying structure. The proposed algorithm relies on alternating projections and is provably convergent. Numerical results corroborate the theoretical findings and the applicability of the proposed algorithm.

Solid Oxide Fuel Cells (SOFCs) are a type of power source that can convert hydrocarbons and hydrogen gas to electricity at temperatures of between 600-800°C with a flow rate of 0.2 l/min. A BYCF cathode, GDC 10 electrolyte and NiO anode were used for the SOFC system. A Spray Pyrolysis technique was used for the fabrication of the cathode and anode layers which were 5-10 µm in thickness. The Micro-SOFC should be able to detect hydrocarbon gases such as methane, butane, and so forth, which can generate a small electrical signal depending on the quantity of gas. Therefore, the novel design of Micro-SOFCs can be used as a sensor for measuring the quantity of methane. In particular, it can measure the content of methane in biogas after fermentation. This investigation used a novel design of sensor surface with Cat, Square, and Yin-Yang shapes. The impedance showed a relationship between resistivity and ionic transfers in the Micro-SOFC system depending on the surface shapes.
