Consumer Preference for Food Bundles under Cognitive Load: A Grocery Shopping Experiment

Product bundling is a common retail marketing strategy. The bundling of food items has the potential to increase profits in the grocery sector, particularly for fresh produce, which often has lower profit margins. Although prior work suggests consumers prefer bundles because they require less cognitive effort to select, no study has yet experimentally manipulated cognitive load when food bundles are included in the choice set. To test whether bundle preference differs when cognitive resources are constrained, a grocery shopping experiment was conducted with 250 consumers in the midwestern U.S., in a laboratory that featured a grocery store display. Consumers who grocery shopped under cognitive load had a higher odds of selecting a food bundle even when the bundle did not offer a price discount. Results suggest food bundles may be preferred because they require less cognitive effort to process, which could benefit consumers by simplifying the grocery shopping experience. Additional factors found to influence food bundle selection included whether the bundled items were perceived as being complementary and hunger levels. Food bundles could help lessen cognitive effort associated with grocery shopping and may especially appeal to those who do not enjoy food shopping.
Perceval S, sutureless aortic valve: cost-consequence analysis

Introduction Sutureless aortic valve prostheses have the potential of shortening ischemic time. Aim We conducted the present study to assess the clinical and economic impact of the biological, sutureless, self-expanding Perceval S valve since the effect of shortened operative times on hospital costs remains unclear. Material and methods This is a retrospective analysis. From January 2018 to January 2019, 29 patients underwent isolated aortic valve replacement with the Crown PRT bioprosthetic Aortic Valve, whereas 35 patients underwent aortic valve replacement with Perceval S (auto-expanded, sutureless, bioprosthesis). Preoperative data, hospital outcome, and health care resource consumption were compared, using χ2 and t-test. Results Aortic cross-clamp, cardiopulmonary bypass, and operation times were significantly shorter in the Perceval S group (p < 0.001). Patients in the sutureless group required blood transfusion less frequently (p = 0.03) and had a shorter intensive care unit (ICU) stay (p = 0.01). Hospital stay (p = 0.57) and pacemaker implantation were similar between groups. The reduction of aortic cross-clamp, extracorporeal circulation times, and ICU stay resulted in reduced resource consumption in the sutureless group. Conclusions The use of the Perceval S valve is clinically safe and effective. A shorter procedural time in the sutureless group is associated with better clinical outcomes and reduced hospital costs.
La réponse humorale contre les peptides antigéniques de Plasmodium falciparum (MSP1, MSP2 et SR-11.1) chez des sujets vivant en zone endémique

Introduction les vaccins constituent les outils privilégiés pour le contrôle et l´éradication du paludisme dans le monde. Actuellement, la recherche et développement est orientée vers trois types de candidats vaccins qui ciblent différents stades de vie du Plasmodium falciparum chez l´homme et le vecteur. L´objectif est d´évaluer la réponse humorale contre les peptides antigéniques de Plasmodium falciparum (MSP1, MSP2 et SR-11.1) chez des sujets vivant en zone endémique. Méthodes nous avons réalisé une étude transversale sur une période de 5 mois portant sur les sérums de 182 sujets Vietnamien vivant dans les aires endémiques. Le sang total a été centrifugé et, le sérum aliquoté dans des cryotubes et conservé à -20°C pour le dosage des immunoglobulines G (IgG). Le dosage des immunoglobulines G totales a été réalisé par la technique ELISA après couplage des peptides avec le glutaraldéhyde. Résultats au total, 182 sérums de sujets Vietnamiens vivant en zone endémique ont été inclus. Dans les différentes tranches d´âges d´études, les IgG totales spécifiques contre les peptides antigéniques (MSP-1; MSP-2 et SR-11.1) de P. falciparum montrent une répartition âge dépendant. Chez les sujets de 3 à 19 ans, le taux des IgG totales spécifiques contre Plasmodium falciparum est moins élevé par rapport à celui des groupes d´âge de plus de 20 ans (p=0.07). La comparaison des taux d´IgG spécifiques contre les peptides antigéniques MSP-1, MSP-2 et SR-11.1 du P. falciparum dans les groupes d´âge, donne une moyenne significativement plus élevée pour MSP-1 et MSP-2 par rapport au taux d´anticorps anti-SR-11.1 (p=0.04). Conclusion nous avons trouvé que le taux des anticorps spécifiques contre les peptides antigéniques (MSP-1; MSP-2 et SR-11.1) de P. falciparum est âge dépendant. Des trois peptides antigéniques, MSP-1 et MSP-2 apparaissent plus immunogènes que SR.11.1. Donc, SR.11.1 est une macromolécule pour le système immunitaire et de ce point de vue apparait nettement moins immunogène que les autres peptides.
Type 2 Diabetes Mellitus as a Risk Factor for Alzheimer’s Disease: Review and Meta-Analysis

Alzheimer’s disease is the most common type of dementia, reaching 60–80% of case totals, and is one of the major global causes of the elderly population’s decline in functionality concerning daily life activities. Epidemiological research has already indicated that, in addition to several others metabolic factors, diabetes mellitus type 2 is a risk factor of Alzheimer’s disease. Many molecular pathways have been described, and at the same time, there are clues that suggest the connection between type 2 diabetes mellitus and Alzheimer’s disease, through specific genes, autophagy, and even inflammatory pathways. A systematic review with meta-analysis was conducted, and its main goal was to reveal the multilevel connection between these diseases.
Green Synthesis and Characterization of Libyan Propolis Nanoparticles and its Biological Activity

The ever-increasing demand for natural products and biotechnology, derived from bees and ultra-modernization of various analytical devices, has facilitated the rational and planned development of biotechnology products with a focus on human health to treat chronic and neglected diseases. This study aimed to prepare, characterize and examine the stability and evaluation of the antioxidant and the antibacterial activity of Libyan propolis. Propolis Nanoparticles PNP were prepared using particle size reduction, then Transmission Electron Microscope (TEM) at a magnification of X 25000, was used for accurate evaluation of the size distribution of NPs. Three different concentration (10, 5, 2.5 mg/ml) of propolis and nano-propolis powder were tested for their 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity. The quantitative antioxidant activity test results using UV Spectrophotometer absorbance at 517 nm. The antibacterial activities of propolis and prepared nano propolis at different concentrations (10, 5 and 2.5mg/ml) were tested on bacterial strain, Klebsiella, human mouth, skin, and surface bacteria using cup cut diffusion method. The findings exhibited that the prepared propolis Nanoparticles (PNPs) were generally non-spherical with a size 100-200 nm. The PNP was a nano-sized particle around 316 nm in diameter. Zeta potential of PNP showed a negative surface charge value (− 48 mV) which was sufficiently high to avoid NPs aggregation. This value represents a stable and dispersed suspension of NPs and disables the tendency of aggregations in a short in period of time. Poly dispersity index (PdI) of synthetized PNP was used as a measurement of the size distribution. PdI values for PrNP were generally uniform with PdI 0.3 indicating monodispersity of the prepared systems. The propolis and PNPs displayed good antioxidant activity with inhibition percentage (77%, 46% and 18%) for propolis and (82%, 66% and 37%) for PNPs. Propolis nanoparticles showed to have more antibacterial effect compared to propolis. Libyan propolis nanoparticles has shown to be potential candidates as antioxidant and antibacterial agent.
Self-Decoupled Dual-Band Shared-Aperture Base Station Antenna Array

A new decoupling concept for dual-band shared-aperture base station antenna arrays is proposed. By loading arrow-shaped decoupling structures in the hollowed regions of the low-band (LB) loop dipole arms, the LB antenna can yield partial reflection to the high-band (HB) antennas, cancelling the HB coupled wave. A dual-band base station antenna array is designed, fabricated and measured based on this decoupling concept. With decoupling, the HB radiation patterns are restored. The co-polarized in-band couplings between the HB antennas are reduced by about 9 dB, reaching > 26.9 dB. The proposed antenna array possesses both cross-band and in-band decoupling abilities, without extra decoupling layer.
Uses of chalcone acetophenone to synthesis heterocyclic compounds with cytotoxic and c-Met kinase activities

ABSTRACT. The aim of present study was the uses of a series of α,β-unsaturated carbonyl compounds (chalcones), in the synthesis of pyridine, pyran, thiophene, thiazole, together with their uses in heterocyclic synthesis. The work has resulted in the synthesis of a variety of 2,5-dihydropyridine, hydrazide-hydrazone, thiophene derivatives, coumarin, pyran and thiazolo[4,5-d]thiazole derivatives. The antitumor activities of the newly synthesized products were carried out against three cancer cell lines namely MCF-7, NCI-H460 and SF-268 and normal human cell line WI38. In addition, the inhibitions of most of the synthesized compounds against c-Met kinase were studied and results showed that many compounds were of high inhibitions, and these are considered as promising anticancer agents. The results obtained encouraged further work in the future. KEY WORDS: Chalcones, Heterocyclic, Pyridine, Pyran, Thiophene, Thiazole, Antitumor Bull. Chem. Soc. Ethiop. 2022, 36(1), 149-172.

A Longitudinal Study of the Microbial Basis of Nitrous Oxide Emissions Within a Long-Term Agricultural Experiment

Much of the global nitrous oxide emissions are derived from agricultural management driving microbial N transformations. Crop rotation, no-till, and cover cropping are feasible conservation agronomic strategies used to prevent N losses to the environment, though their effect on soil microbial N cycling at the field scale remains relatively unknown. Our goal was to determine the effect of crop rotation (continuous corn [Zea mays L.], CCC; and continuous soybean [Glycine max (L.) Merr. ], SSS), tillage (no-till, NT; and chisel tillage, T), and cover crops (cover crop mixture, CC; and no cover crop, NCC) on the quantification of functional genes related to the N cycle from different times throughout the growing season. The study was conducted during the growing season of the cash crops following the first season of cover crops introduced after 23 years of management. Using quantitative polymerase chain reaction (qPCR) techniques, we quantified nifH (N2 fixation), amoA (nitrification) and nirK, nirS, and nosZ (denitrification). Our results show that CCC increased nitrous oxide emissions by 44% compared to SSS and reduced soil pH by nearly 1 unit. The reduction in soil pH, coupled with an increase in fertilizer-derived ammonium, caused ammonia-oxidizing bacteria (AOB) and nirK copy numbers to increase. The SSS rotation showed opposite results. Bacterial denitrification via the nirK pathway was likely the N cycle mechanism behind nitrous oxide emissions in CCC. The cover crop mixture of cereal rye [Secale cereale L. ] and hairy vetch [Vicia villosa Roth] reduced soil nitrate levels, though they did increase nitrous oxide emissions, likely due to priming and the inclusion of a legume in the cover crop mixture. Nitrous oxide emissions were affected by sampling date, crop rotation, and cover crop use, suggesting management factors that add abundantly available N alter the microbial N cycle directly or indirectly. Chisel tillage increased the abundance of all N cycle genes compared to no-till. Together, our work adds further insight into the microbial N cycle, especially nitrous oxide evolution, from three common conservation agricultural management practices, contributing to our understanding of key soil biogeochemical processes.
Optimal Search Engine Marketing Strategy Customer Behaviour (Case studies from Saudi Arabia): استراتيجية التسويق الأمثل عبر محرك البحث: فهم سلوك العملاء (دراسات حالة من المملكة العربية السعودية)

In the era of the information age, it is normal for a business to have an online attendance on the Internet. However, existence alone is insufficient; the business has to be obviously visible on the search engine whenever a user searches for a product or service provided by that type of business in order to survive and thrive in a competitive market. Thus, the significance of an optimal search engine marketing strategy is extremely important for marketers in particular and for businesses. This study, two case studies from Saudi Arabia were selected to explore this subject. The essay considered how the two selected case studies use Search Engine Optimization (SEO) and paid listings such as Pay Per Click (PPC). Data was gathered from secondary data such as that provided by government departments and business reports. The objective of this study is to understand and explore the massive contribution of paid listings and SEO as search engine tools, to examine how both can serve to raise the number of user/potential customer visits to business websites and to determine what the major challenges are with respect to when and why marketers should use paid listings and/or SEO. This Study found that both case studies invest a low budget in their SEO. In contrast, they both devoted a larger part of their search engine marketing budgets to PPC. However, it was found that SEO brings a higher number of clicks compared to PPC, suggesting that more visitors/users that business could be converted into actual customers. The recommendations of this study can be used to guide the marketers to correct their choice of an optimal search engine marketing strategy, in turn allowing businesses to more accurately determine their online marketing budget.
Study of Silicon Carbide Power MOSFETs Behaviour in Out-of-SOA Conditions

The need for efficient conversion and control of electrical power in many application areas has rapidly increased the demand for power devices with better and better performances. In order to go beyond the limit imposed by Silicon devices, there has always been a great interest for new materials. In recent years, Silicon Carbide Power devices, mainly power diodes and MOSFETs, have become commercially available and have begun to replace their Silicon counterpart in many application areas. The reason lays in some superior material properties that allow developing higher efficient power systems. Nevertheless, a wider spread of these devices could not be achieved without a deep analysis of the elements that might affect their reliability. The current work deals with the study of SiC Power MOSFETs reliability, with particular focus on short-circuit operation. To achieve this purpose, wide set of experiments has been carried out on commercially available devices, providing both electrical and thermal characterization. Alongside experimental evidences, TCAD simulations have been used to get a full understanding of the inner physical failure dynamics. Eventually, it has been possible to give explanation about SiC Power MOSFETs failure mechanisms. In particular, two different phenomena might occur and both are related to temperature increase inside the device.
Psychosocial problems and cognitive functions in children with spina bifida

Objectives This study aims to assess psychosocial functioning in relation to lesion level and ambulatory status in children with spina bifida (SB) and compare them to their peers. Patients and methods Between March 2013 and May 2013, a total of 31 patients with SB (11 males, 20 females; mean age: 9.4 years; range, 6 to 14.7 years) and 36 typically developing peers (16 males, 20 females; mean age: 9.8 years; range, 6.5 to 14.8 years) were included in the study. All participants were assessed using a semi-structured psychiatric diagnostic interview via the Kiddie Schedule for Affective Disorders and Schizophrenia Present and Lifetime Version (K-SADS-PL), Wechsler Intelligence Scale for Children-Revised (WISC-R), Behavioral Rating Inventory of Executive Functions (BRIEF) parent form, Social Responsiveness Scale (SRS), and Aberrant Behavior Checklist (ABC). Results In the SB group, the rate of psychiatric disorders was significantly higher (p=0.001) and the SRS scores and the planning and organizational components of the executive function were higher than their peers (p=0.02 and p=0.007, respectively). The psychiatric diagnosis rate, BRIEF, and SRS total scores did not significantly differ according to lesion level and ambulatory status. The BRIEF initiate and organization of materials subtest scores and ABC scores were significantly lower at high lesion levels (p=0.02, p=0.02, and p=0.02, respectively) and non-community walkers (p=0.002, p=0.03, and p=0.003, respectively). Conclusion Psychiatric disorders, impairment in social responsiveness, and planning and organization components of the executive function are prevalent in children with SB with no intellectual disabilities, compared to their peers. Therefore, psychosocial counseling and multidisciplinary follow-up for SB patients seem to be beneficial.

IoT and AI-Based Application for Automatic Interpretation of the Affective State of Children Diagnosed with Autism

In the context in which it was demonstrated that humanoid robots are efficient in helping children diagnosed with autism in exploring their affective state, this paper underlines and proves the efficiency of a previously developed machine learning-based mobile application called PandaSays, which was improved and integrated with an Alpha 1 Pro robot, and discusses performance evaluations using deep convolutional neural networks and residual neural networks. The model trained with MobileNet convolutional neural network had an accuracy of 56.25%, performing better than ResNet50 and VGG16. A strategy for commanding the Alpha 1 Pro robot without its native application was also established and a robot module was developed that includes the communication protocols with the application PandaSays. The output of the machine learning algorithm involved in PandaSays is sent to the humanoid robot to execute some actions as singing, dancing, and so on. Alpha 1 Pro has its own programming language—Blockly—and, in order to give the robot specific commands, Bluetooth programming is used, with the help of a Raspberry Pi. Therefore, the robot motions can be controlled based on the corresponding protocols. The tests have proved the robustness of the whole solution.
A Music Genre Classification Method Based on Deep Learning

Digital music resources have exploded in popularity since the dawn of the digital music age. The music genre is an important classification to use when describing music. The function of music labels in discovering and separating digital music resources is crucial. In the face of a huge music database, relying on manual annotation to classify will consume a lot of cost and time, which cannot meet the needs of the times. The following are the paper’s primary research findings and innovations: to better describe the music, this article will be divided into multiple local musical instrument digital interface (MIDI) music passages, playing style close by analyzing passages, passages feature extracting, and feature sequence of passages. Extraction of note feature matrix, extraction of topic and segment division based on note feature matrix, research and extraction of effective features based on segment theme, and composition of feature sequence are all part of the process. Because of the shallow structure of standard classification methods, it is difficult for classifiers to learn temporal and semantic information about music. This research investigates recurrent neural networks (RNN) and attention using the distinctive sequence of input MIDI segments. To create data sets and conduct music categorization tests, collect 1920 MIDI files with genre labels from the Internet. The method for music classification is validated when it is combined with the experimental accuracy of equal length segment categorization.
