Mixed-mode fracture prediction of acrylonitrile butadiene styrene material fabricated via fused deposition modeling

Fused deposition modeling is one of the additive manufacturing techniques that is used for rapid manufacturing and prototyping, in various industries. Due to the layer-wise fabrication routine in the fused deposition modeling process, the final fabricated products often show anisotropic behavior. As a result, to investigate the mechanical performance of the three-dimensional-printed parts, complex and time-consuming analyses are required. The main purpose of the current research paper is to determine whether the isotropic assumption of material using maximum tangential stress and mean stress criteria is capable of predicting the mixed-mode fracture resistance of the three-dimensional -printed parts. Here, three different building conditions are considered for fabricating tensile and fracture specimens, and various mechanical and fracture characteristics are evaluated. Finite element simulations of the test specimens are executed and the stress results are used as input for fracture prediction of the fused deposition modeling parts. Two different cases are considered for isotropic assumptions wherein the first case (case A), each fracture specimen is modeled by using its own direct mechanical properties. While in the second case (case B), the average mechanical properties are used for modeling the cracked specimens. The results showed that both maximum tangential stress and mean stress criteria can predict the fracture loads of the fused deposition modeling parts, without the need for complex and time-consuming analyses associated with fully anisotropic materials. In addition, an improvement of the predictions was observed while using case A compared to case B.
Optical lattices: cold atoms ordered by light

We present here an introduction to optical lattices starting from the basic concepts of laser cooling of neutral atoms. Ordered structures, composed of cold atoms in an interference pattern, are then described, with a particular emphasis on the basic mechanism called Sisyphus cooling. Afterwards, we introduce the basic elements of the main physical problem (an atom moving in a spatially modulated electromagnetic field) and we make a concise description of the various theoretical approaches that have been introduced in the literature in order to solve that problem. Finally, we report a detailed list of the multiple diagnostic tools that have been developed by physicists in order to investigate the static and dynamical properties of these systems. The new developments and the perspectives of the research field on optical lattices are then quickly discussed and conclude this introductory review.
Comparison of clinical severity, genotype and toxin gene expression of binary toxin-producing Clostridioides difficile clinical isolates in Japan

The emerging Clostridioides difficile strain BI/NAP1/027 has been reported to be associated with more severe clinical symptoms and higher mortality rates, thought in part due to production of a novel binary toxin alongside conventional A and B toxins. However, recent studies suggest that this may not always be the case. Therefore, the purpose of this report was to investigate the correlation between clinical severity and microbiological characteristics of CDT-producing C. difficile isolates in Japan. Eight Japanese isolates of CDT producing C. difficile were investigated using genotyping, cytotoxic activity assays and toxin gene expression. Correlation with clinical severity was performed retrospectively using the patient record. Three of eight patients were assessed as having severe C. difficile infection (CDI). PCR ribotyping resolved six ribotypes including ribotype 027. No specific genes were identified determining severe compared with non-severe cases. Positive correlation of expression levels of tcdA, tcdB and cdtB were observed although these expression levels were not correlated with cytotoxicity. CDI severity index neither correlated with toxin gene expression level nor cytotoxicity. These data indicate that the possession of the CDT gene and toxin gene expression levels may not relate to C. difficile cytotoxicity or clinical severity.
Effect of Travel Expenditure on Life Satisfaction for Middle-Aged and Older Adults in Korea: Moderating Effect of COVID-19 Pandemic

The aim of this research was to examine the effects of travel expenditures on life satisfaction in the context of the COVID-19 pandemic. For the research, a curvilinear relationship was established between life satisfaction and travel expenditures that was then compared between 2018 and 2020. The study subjects were middle-aged and older adults who completed the 2018 and 2020 waves of the Korean Longitudinal Study of Aging. Demographic, travel expenditure, and life satisfaction data were collected, and quadratic regression analysis was conducted to examine the effects of travel expenditures on life satisfaction before and during the COVID-19 pandemic. The first-order condition was computed to determine the optimal level of travel expenditures to maximize life satisfaction, and the results exhibit that the utility of travel expenditure decreased during the COVID-19 pandemic.
Forecasting onion price for Varanasi market of Uttar Pradesh, India

The onion crop is widely seen as the poor man's vegetable, has the power to change electoral results (Anonymous 2019). In India Onion (Allium cepa) is cultivated in an area of 12.7 lakh ha and produces 215.64 lakh ton. In Uttar Pradesh it is cultivated in an area of 0.25 lakh ha producing 4.23 lakh ton. The study was done during 2020 at IARI, New Delhi. Development of appropriate price forecasting mechanism and dissemination among the farmers would help alleviate problems faced by the farmers and consumers alike. The average price of onion throughout the year, during the study period of 2015-2020, has been fluctuating between ₹ 900-2200/quintal. The ARIMA (0,1,2)(1,0,0) [52] and ARFIMA(3,0,0)-sGARCH (1,1) model were found to be best fit model. However, on the basis of MAPE, MSE, RMSE and Theil's U statistics it was observed that the ARMA-GARCH model outperformed the ARIMA model.
An extended Kalman filter based sensorless direct vector control of induction motors

In this study, it is aimed to design a rotor-oriented sensorless direct vector control for the speed control of an induction motor (IM). For this purpose, all the states required for direct vector control in addition to the step-shaped load torque and rotor resistance are estimated using extended Kalman Filter (EKF). Simulation results demonstrate a good performance and robustness to variations of load and rotor resistance.
Optimization of Bioactive Compound Extraction from Eggplant Peel by Response Surface Methodology: Ultrasound-Assisted Solvent Qualitative and Quantitative Effect

Anthocyanin pigments, which the peel of eggplant is rich in, contribute to food quality because of their function in color, appearance, and nutritional advantages. For the first time, this study aimed to optimize the composition of the extracting solvent as three factors: factor A (ratio of ethanol to methanol 0–100% v/v), factor B (ratio of water to alcohol 0–100% v/v), and factor C (citric acid in the final solvent 0–1% w/v) using response surface methodology (RSM), central composite design (CCD) with α 2, and two repeats in axial and factorial points and four central points, for maximum total phenolic content, total anthocyanin content, extraction yield, antioxidant activity in terms of DPPH radical scavenging activity and ferric reducing antioxidant power (FRAP) assay of the eggplant peel dry extract assisted by ultrasound (200 watts power, frequency of 28 kHz) in 60 °C for 45 min has been investigated. The best optimal formulas determined using RSM for the final solvent comprised optimal formula 1 (i.e., ethanol-to-methanol ratio 59% and water-to-alcohol ratio 0%, and citric acid in final solvent 0.47%), and optimal formula 2 (i.e., ethanol-to-methanol ratio 67% and water-to-alcohol ratio 0%, and citric acid in final solvent 0.56%). In general, an alcoholic–acidic extract of eggplant peel made with an ethanol–methanol solvent including citric acid can be used in the food industry as a natural source of antioxidants and pigment.
V‐model with fuzzy quality function deployments for mobile application development

Mobile application (app) development is a subset of software development distinguished by a short development life cycle, rapidly changing business requirements, mobile device technical specifications, and operating system compatibility. The study presents a V‐model mobile app development technique that combines two fuzzy quality function deployment (FQFD) phases. In mobile app development, user requirements are often misunderstood, resulting in poor mobile app design. The research motivation for employing FQFD is to obtain more accurate deductions of human (user or design team) inputs affected by intrinsic vagueness and ambiguity in linguistics. The combination hence delivers synergistic benefits, where FQFDs more effectively solicits and breaks down the voice of the customer (VOC) and system requirements, and the V‐model aligns the development to the broken‐down requirements. The development of an online statistical process control app was demonstrated. FQFD structurally related user requirements, system requirements, and design strategies in the V‐model's verification phases. The validation phases used test plans created during the verification phases to detect and correct programming errors. In the final validation stage, the focus group agreed that the mobile app met all of the user requirements. This study adds to the methodology's novelty by proposing and demonstrating the integration of the FQFD and V‐model into the development of mobile apps. As a result of the limitation, other areas of software engineering, such as time and resource coordination and release management, are not considered.
An alternative symbiotic channel to Type Ia supernovae

By assuming an aspherical stellar wind with an equatorial disc from a red giant, we investigate the production of Type Ia supernovae (SNe Ia) via a symbiotic channel. We estimate that the Galactic birthrate of SNe Ia via the symbiotic channel is between 1.03 x 10(-3) and 2.27 x 10(-5) yr(-1), while the delay time of SNe Ia has a wide range from similar to 0.07 to 5 Gyr. The results are greatly affected by the outflow velocity and mass-loss rate of the equatorial disc. Using our model, we discuss the progenitors of SN 2002ic and SN 2006X.
Proof techniques for recursive programs

Abstract : The concept of least fixed-point of a continuous function can be considered as the unifying thread of the report. The connections between fixed- points and recursive programs are detailed in Chapter 2, providing some insights on practical implementations of recursion. There are two usual characterizations of the least fixed-point of a continuous function. To the first characterization, due to Knaster and Tarski, corresponds a class of proof techniques for programs, as described in Chapter 3. The other characterization of least fixed points, better known as Kleene's first recursive theorem, is discussed in Chapter 4. It has the advantage of being effective and it leads to a wider class of proof techniques.
Realizing recrystallization-stabilization temperature range inversion in high Mg content Al alloys via pulsed electric current

ABSTRACT A longstanding challenge with high Mg content Al alloys is the trade-off between corrosion resistance and strength, because the stabilization temperature is lower than the recrystallization temperature corresponding to a no stabilization temperature range. Herein, a stabilization temperature range is found with an excellent match of strength and corrosion resistance of high Mg content Al alloy via pulsed electric current. The stimulated atomic diffusion rate resulted in discontinuous grain boundary precipitates, along with a lower electric wind force development rate to maintain dislocation strengthening. These results provide insights into developing high-performance Al-Mg alloys by the pulsed electric field treatment. GRAPHICAL ABSTRACT IMPACT STATEMENT The pulsed electric current treatment provides a new measure to develop high-performance Al alloys with high Mg content, improving the corrosion resistance while ensuring dislocation strengthening.
A reddening-free method to estimate the $^{56}$Ni mass of Type Ia supernovae

The increase in the number of Type Ia supernovae (SNe\,Ia) has demonstrated that the population shows larger diversity than has been assumed in the past. The reasons (e.g. parent population, explosion mechanism) for this diversity remain largely unknown. We have investigated a sample of SNe\,Ia near-infrared light curves and have correlated the phase of the second maximum with the bolometric peak luminosity. The peak bolometric luminosity is related to the time of the second maximum (relative to the {\it B} light curve maximum) as follows : $L_{max}(10^{43} erg s^{-1}) = (0.039 \pm 0.004) \times t_2(J)(days) + (0.013 \pm 0.106)$. $^{56}$Ni masses can be derived from the peak luminosity based on Arnett's rule, which states that the luminosity at maximum is equal to instantaneous energy generated by the nickel decay. We check this assumption against recent radiative-transfer calculations of Chandrasekhar-mass delayed detonation models and find this assumption is valid to within 10\% in recent radiative-transfer calculations of Chandrasekhar-mass delayed detonation models. The $L_{max}$ vs. $t_2$ relation is applied to a sample of 40 additional SNe\,Ia with significant reddening ($E(B-V) >$ 0.1 mag) and a reddening-free bolometric luminosity function of SNe~Ia is established. The method is tested with the $^{56}$Ni mass measurement from the direct observation of $\gamma-$rays in the heavily absorbed SN 2014J and found to be fully consistent. Super-Chandrasekhar-mass explosions, in particular SN\,2007if, do not follow the relations between peak luminosity and second IR maximum. This may point to an additional energy source contributing at maximum light. The luminosity function of SNe\,Ia is constructed and is shown to be asymmetric with a tail of low-luminosity objects and a rather sharp high-luminosity cutoff, although it might be influenced by selection effects.
LEVERAGING VOICE ASSISTIVE TECHNOLOGY TO ENHANCE HEALTH MONITORING OF OLDER ADULTS

With the growing population of older adults, the need for mHealth to address specific aging features is also increasing. However, various research and usability studies on those mHealth applications indicate that mHealth is still not planned with older adults and their needs in mind. It is critical to gain insight into aging obstacles that affect the usability of mHealth as encountered by older adults in order to improve mHealth designs targeted at this demographic. Voice as a new interaction modality has been heavily emphasized in recent product launches such as Apple's Siri and Google's Voice Search. A user-centered design methodology was used to create a mobile health application to help independent living older adults keep track of their health and routine in this research. To help these individuals, I have designed CORE-Energy, a conceptual context-aware assistive application by integrating a language-technology-driven interface into mHealth. First, a Survey on mHealth was conducted to gather the opinion of various stakeholders. The functional design criteria used to direct the design were identified through an analysis of the data collected during this process. Integration of VUI, keeping track of Blood pressure, blood sugar, body temperature, and fitness tracking functionality was explored using a rapid prototyping method. The ease of use and perceived usefulness of the final prototype produced in this study were assessed. After conducting usability testing on 5 users, this application received a System Usability Scale (SUS) score of 75.4%, which indicates that the interface was found to be user-friendly in general. The application created during the research work can be extended to create a more diversified set of voice input to make the user experience even smoother.
Good Practices in Perinatal Mental Health for Women during Wars and Migrations: A Narrative Synthesis from the COST Action Riseup-PPD in the Context of the War in Ukraine

Background: Since February 24th, 2022, the beginning of Russia's aggression against Ukraine, more than 80,000 women were expected to give birth. Therefore, understanding the impact of war on the perinatal health of women is an important requisite to improve perinatal care. This narrative synthesis has two main purposes: on one hand, it aims to summarize the current evidence available based on perinatal health outcomes and care among perinatal women;on the other, it attempts to identify the gaps still present in research in relation to perinatal care. Method: A literature search was completed in diverse databases (e.g., Medline, PsychInfo). Results: Emergent matters related to practice and research in perinatal refugee women have been discussed. Conclusions: In the face of the war in Ukraine, we need to build up further research to provide an evidence-based foundation for preventing and treating the psychological consequences of pregnant women exposed directly to war and those who have been forced into a refugee status during this vulnerable period. Also, it is essential to support not only women transitioning to motherhood, but also supporting midwives and nurses in their work.
Occurrence of Zearalenone and Enniatin B in Swiss Wheat Grains and Wheat Flours

Wheat is one of the world’s key staple foods, but it is often contaminated with mycotoxin-producing microorganisms, resulting in a large amount of food waste every year. The contamination of wheat grains harvested in 2020 and 2021 in Switzerland, as well as of wheat flours bought in local stores with the two mycotoxins zearalenone (ZEA) and enniatin B (ENB) was investigated. The quantification was performed using LC–MS/MS. ZEA, the level in different cereals and food products of which is regulated by law, was detected in half of the grain samples at levels below 100 µg/kg, except for one sample contaminated with 147 µg/kg. No ZEA was detected in the commercial wheat flours. The emerging mycotoxin ENB was detected in all samples of wheat grains and flours, at levels between 3 and 938 µg/kg. The harvest year was shown to affect the ENB content (p value < 0.01), and in particular the humid weather conditions encountered in 2021 during the month of harvest. The refining grade of the flours showed no influence on the contamination by ENB, indicating that the contamination with ENB can occur not only on the surface layers but also on the inner layers on the wheat grain. As chronic exposure to ENB can therefore not be excluded, decontamination solutions are needed to prevent food waste and further improve the food safety of wheat-based products.
Properties of exact density functionals for electronic quantum transport

Density functional theory and its extension in the nonequilibrium regime, time-dependent density functional theory, are powerful tools for predicting the structures, energies and dynamics of electronic systems. Their usefulness derives from the Kohn-Sham scheme whereby a system of real, interacting particles is replaced by a fictitious system of non-interacting particles subject to an effective external potential instead of a pairwise particle-particle interaction. The Kohn-Sham universe yields the same observable phenomena as that predicted by standard quantum mechanics so long as the effective external potential is known. However, for the vast majority of systems it is not known, and the usually local (in time and space) functional approximations employed do not capture the physics of true nonlocal interactions. In this thesis, the exact charge and current densities of model quantum transport devices described by nonlocal potentials are studied and methods for reverse-engineering the corresponding exact Kohn-Sham effective external potential for time-dependent and steady-state density functional theory approaches to the same systems are presented, as well as the resulting exact potentials themselves. Features of improved functionals for calculating approximate Kohn-Sham systems are demonstrated. These functionals are suggested to be very different from existing functionals employed, describing not potentials but electric and magnetic fields, and have a strong dependence on the local and semilocal charge and current density.
Interleukin-8 in Colorectal Cancer: A Systematic Review and Meta-Analysis of Its Potential Role as a Prognostic Biomarker

Among soluble actors that have emerged as druggable factors, the chemokine interleukin-8 (IL-8) has emerged as a possible determinant of response to immunotherapy and targeted treatment in several cancer types; however, its prognostic/predictive role in colorectal cancer (CRC) remains to be established. We: (i) conducted a systematic review of published literature on IL-8 expression in CRC; (ii) searched public transcriptomics databases; (iii) investigated IL-8 expression, by tumor and infiltrating cells, in a series of CRC samples; and (iv) carried out a meta-analysis of published literature correlating IL-8 expression and CRC prognosis. IL-8 possesses an important role as a mediator of the bidirectional crosstalk between tumor/stromal cells. Transcriptomic analysis indicated that specific IL-8 transcripts were significantly overexpressed in CRC compared to normal colon mucosa. Moreover, in our series we observed a statistically significant correlation between PTEN-loss and IL-8 expression by infiltrating mononuclear and tumor cells. In total, 12 papers met our meta-analysis inclusion criteria, demonstrating that high IL-8 levels significantly correlated with shorter overall survival and progression-free survival. Sensitivity analysis demonstrated a highly significant correlation with outcome for circulating, but not for tissue-detected, IL-8. IL-8 is overexpressed in CRC tissues and differentially produced by tumor or stromal components depending on CRC genetic background. Moreover, circulating IL-8 represents a strong prognostic factor in CRC, suggesting its use in the refining of prognostic CRC assessment and potentially the tailoring of therapeutic strategies in individual CRC patients.
