Fish canning identified machine learning utilizing three-dimensional images through X-ray computed tomography

Canned mackerel is popular and has become a vital commodity in the modern consumer market. It is important to preserve product value, maintaining the intact appearance of the mackerel. Although a sampling inspection can be performed by opening cans during shipment, this approach renders the product unsellable. There are required methods that enable judgments regarding quality without the opening of cans. Bones could be visualized, but the canned fish meat surrounding the bones remains challenging to observe through X-ray computed tomography (CT). This study confirmed that machine learning could effectively discern these minute discrepancies. This study revealed that a reasonably accurate discrimination could be achieved with approximately 35 pieces of training data. These results will be applications in identifying cans with issues like peeling skin or flesh, effectively discerning substantial differences.

A linear photonic swap test circuit for quantum kernel estimation

Abstract The swap test is a quantum algorithm capable of computing the absolute value of the scalar product of two arbitrary wavefunctions. Scalar products represent a crucial ingredient to many QML methods, but their evaluation is not straightforward at all. For this reason, many research efforts have been made without achieving an efficient and robust implementation. Here, we present an integrated photonic circuit designed to implement the swap test algorithm. Our approach relies solely on linear optical integrated components and qudits, represented by single photons from an attenuated laser beam propagating through a set of waveguides. By utilizing 2$^3$ spatial degrees of freedom for the qudits, we can configure all the necessary arrangements to set any two-qubit state and perform the swap test. This simplifies the requirements on the circuitry elements and eliminates the need for non-linearity, heralding, or post-selection to achieve multi-qubit gates. Our photonic swap test circuit successfully encodes two qubits and estimates their scalar product with a measured root mean square error smaller than 0.05. This result paves the way for the development of integrated photonic architectures capable of performing Quantum Machine Learning tasks with robust devices operating at room temperature.

Instinct(ive) senses: the haptic experience of feminist postpornography

ABSTRACT Is feminist postpornography a medium through which it might be possible to experience porn not only from a voyeuristic perspective? Can feminist postpornography provide a deeper sensorial experience? Through the feminist close-reading analysis of one short film, Instinct (2019), directed by Marit Östberg, Adrienne Teicher, Ester Martin Bergsmark and Mad Kate, from the Swedish feminist porn collection Dirty Diaries (2019), this article demonstrates how this kind of approach to pornography can awake senses and lead the spectators to experience porn at a deeper level stimulating an engaged spectatorship. Spectators are active agents in the construction of meaning and value of the artistic product, going beyond the mere passive role of recipient of information. The analysis employs mainly Laura Marks’s concepts of “haptic visuality” and “haptic hearing,” as well as Irina Leimbacher’s “haptic listening,” together with key insights of feminist film theory.

MICE tourism product value chain

MICE tourism is a segment of the tourism industry that, due to its singularity, requires specific attention. This article offers a holistic approach to the channel of distribution of MICE tourism and targets two main objectives: the proposal of a conceptual framework that depicts all stakeholders, flows of action and possibilities of intermediation and study of the process of intermediation in order to analyze its present status and future development. To achieve our goal in this study, we used research methods - literature analysis, study of scientific publications, scientific research, and also used the construction of tables and diagrams of interaction between the main stakeholders of MICE tourism. When analyzing materials and writing this article, the following methods were used: general scientific methods of cognition (analysis, synthesis, systematization of theoretical data), system content analysis. The results observe a slow but steady process of disintermediation in which intermediaries are being bypassed in order to reduce costs. However, it also reaches the conclusion that total disintermediation is not feasible due to the high standards of quality service that the MICE market demands.

Competitive price perceptions that align with product value also boost satisfaction and trust. Managerially, businesses should prioritize continuous product innovation, robust after-sales services, and strategic price management to improve perceived value. These strategies are essential for achieving higher customer satisfaction and building strong brand trust, ultimately supporting sustainable growth and increased market share

Aflatoxin B1 in senna pods from field to storage in Tamil Nadu, India

ABSTRACT Senna, a medicinal herb, is highly susceptible to aflatoxin contamination, which often limits the export value of the final products due to the regulatory limits of importing countries. Presence of aflatoxin B1 (AFB1) was investigated in 229 senna pod samples at various stages from field to storage over three years. Higher incidence of AFB1 was revealed during the late harvest stage with a mean level of 52.4 µg/kg and a range of LOD-206 µg/kg. Out of 48 late harvest samples, 37 exceeded the AFFB1 limit of 2 µg/kg. In contrast, the majority of preharvest samples showed lower levels of AFB1 (1.0 µg/kg). During drying, increase in the mean AFB1 level to 4 µg/kg was observed and it could further increase to 18.1 μg/kg in storage. These results highlight the status of aflatoxin contamination in senna pods and emphasise the importance of implementing good agricultural practices in senna cultivation to mitigate AFB1 contamination.

High-Pressure Processing of Milk and Dairy Products: Latest Update

Leukocyte Extracellular Vesicles Predict Progression of Systolic Dysfunction in Heart Failure with Mildly Reduced Ejection Fraction (LYCHEE) - A Prospective, Multicentre Cohort Study.

Risk stratification in heart failure with mildly-reduced ejection fraction (HFmrEF) remains challenging. We evaluated the predictive value of advanced glycation end products (AGEs) and plasma concentrations of extracellular vesicles (EVs) for the systolic and diastolic dysfunction progression in HFmrEF patients. Skin AGE accumulation was measured using AGE Reader. Plasma EV concentrations were measured using flow cytometry. Among 74 patients enrolled, 13 (18%) had systolic dysfunction progression and 5 (7%) had diastolic dysfunction progression during 6.5months follow-up. Leukocyte EVs concentrations were higher in patients with systolic dysfunction progression (p = 0.002) and predicted the progression with 75.0% sensitivity and 58.3% specificity, independent of other clinical variables (OR 4.72, 95% CI 0.99-22.31). Skin AGE levels and concentrations of other EV subtypes were not associated with systolic or diastolic dysfunction progression. Increased leukocyte EVs concentrations are associated with 4.7-fold higher odds of systolic dysfunction progression in HFmrEF patients.

Predicting the higher heating value of products through solid yield in torrefaction process

Torrefaction is a widely employed method to upgrade biomass for energy purpose. The higher heating value (HHV) serves as a vital indicator for assessing the energy potential of biomass. Nevertheless, HHV measurement is a time-consuming and costly process. HHV of raw biomass, torrefied biomass, and biochar has been extensively estimated using the results of elemental analysis and/or proximate analysis. However, these data must be repeatedly measured for each target object. To reduce the efforts required for the measurement of each object, this study proposes, for the first time, the use of solid yield (the most easily obtainable data) to predict the HHV of torrefied biomass.A total of 215 sets of data were retrieved from different biomass types undergoing various torrefaction technologies. Artificial neural network (ANN) and hierarchical linear regression (HLR) were employed to develop prediction models. Solid yield demonstrated a clear correlation to HHV for each individual biomass; however, diverse biomass types exhibited significant variation. Therefore, the results of elemental analysis of raw feedstocks were incorporated to account for variations in feedstock types and to iterate the models. Generally, ANN is superior to HLR in predicting the HHV of torrefied biomass with the optimized model achieving an R2 of 0.9133. Additionally, two biomasses subjected to two torrefaction technologies were used to validate the model, and an R2 of 0.9676 was achieved.As a result, in a torrefaction process, once the raw biomass is analyzed, the HHV of any torrefied biomass can be predicted simply by measuring the weight of the product.

Проблема ценности в цифровом обществе роевого интеллекта

Introduction. The emerging digital society demonstrates the problem of justifying the value, worth and price of digital products and services, which requires consideration of the specificity of value in this society. Theoretical analysis. Following the financial and art market, the boundary between “value” and “worth” is blurred in the digital society. Value, including the value of an individual, becomes variable and is conditioned by the presence of unique attributes and unique experiences that obtain market value. At the same time, under standard digital protocols and technologies, the true uniqueness of an individual experience can only be achieved through the creation of customized digital ecosystems in the form of robotic swarms that support human life activities. A set of digital devices that have sufficient resources to continuously self-renew and form a closed environment around the individual that provides a unique experience can be called a chrysalic swarm. The chrysalic swarm creates an opportunity for the individual to escape from the logic of mutual competition dictated by society. Conclusion. Studying the value problematization in the digital society of swarm intelligence opens a theoretical perspective on the problem of the crisis of social elites in the context of the fulfillment of this scenario of society development.

Table Olive Powder: A new ingredient from food industry discards

This study aimed to obtain olive powder from table olive industry discards to use it as a valuable ingredient for developing new products or for replacing commercial additives. The drying process was conducted by convective drying (50 °C and 70 °C) and freeze-drying. The raw material came from Spanish-style green pitted olives and anchovy-stuffed olives. Table olive powders were characterised by their proximate composition, physico-chemical characteristics, antioxidant properties and lipid oxidation. The drying process did not affect the final product's nutritional value, which was determined mainly by the employed raw material, but high temperatures strongly impacted colour and caused a reduction in the bioactive compounds between 60 and 70 %. The freeze-dried table olive powder had the highest phenolic content at over 2500 mg GAE/kg and antioxidant properties, which reduce product lipid oxidation below 2 mg MDA/kg. This work expounds the best drying process to obtain a novel high-quality ingredient from table olive discards.

“They don't care what we watch”: On ratings and culture‐making in the dizi industry

AbstractThis article challenges Western‐centric assumptions in existing media theories that assume a relatively democratic society by exploring the media worlds of dizis, Turkey's globally famous, serialized television melodramas. It examines dizi makers' frustrations with a recently revised rating system at a time when Turkey's conservative and authoritarian‐leaning ruling AKP elite increasingly intervene in the country's cultural field. The article argues that in Turkey's highly polarized, authoritarian context, ratings become a crucial site of culture‐making, through which Turkish culture, the value of cultural products like dizis, and the place of their creators in Turkey's cultural hegemony get renegotiated. Exploring the resentments of today's dizi makers reveals that contemporary Turkish power contestations cannot be reduced to either the secular/religious binary or to class dynamics alone, as often deployed to explain the current polarization between Erdoğan's supporters and his dissidents. The article also demonstrates the need for more rigorous theorizing about how states—as repressive actors in authoritarian contexts—affect the worlds of media creators and their works.

How perceived value of augmented reality shopping drives psychological ownership

PurposeThis study proposes a framework that demonstrates how the perceived value of augmented reality (AR) shopping influences the formation of psychological ownership of product and technology. The mediating role of flow experience and the moderating role of perceived control are identified.Design/methodology/approachAn online survey study recruiting 480 participants who experienced AR shopping was conducted to test the hypotheses.FindingsFunctional value is negatively related to psychological ownership of product and technology whereas emotional value shows opposite effects. Flow experience mediates the relationships between functional/emotional value and psychological ownership of product and technology. Perceived control moderates the relationship between emotional value and flow experience, as well as the relationship between functional/emotional value and psychological ownership of product and technology.Practical implicationsThe findings suggest the importance of AR’s functional and emotional values in developing psychological ownership of product and technology. To mitigate the negative effect of functional value, AR designers should focus on creating emotionally engaging apps that induce a flow experience, thereby enhancing psychological ownership. Furthermore, AR apps should be designed to empower users with a sense of control in the AR experience.Originality/valueThis research contributes to the AR and psychological ownership literature. It introduces a model that can explain both the formation of psychological ownership of product and psychological ownership of technology, thereby expanding the current understanding. By adding perceived values as antecedents of psychological ownership, it enriches the psychological ownership literature. Moreover, it enhances the flow experience literature by demonstrating the role of flow experience in the formation of psychological ownership of product and technology.

The resulting samples are uniform in color, the surface color is brown, the softness of the bread is elastic, soft, porous, without foreign odors and the taste harmoniously matches the gluten[1]free bread product.

A new electrolyte for molten carbonate decarbonization

The molten Li2CO3 transformation of CO2 to oxygen and graphene nanocarbons (GNCs), such as carbon nanotubes, is a large scale process of CO2 removal to mitigate climate change. Sustainability benefits include the stability and storage of the products, and the GNC product value is an incentive for carbon removal. However, high Li2CO3 cost and its competitive use as the primary raw material for EV batteries are obstacles. Common alternative alkali or alkali earth carbonates are ineffective substitutes due to impure GNC products or high energy limitations. A new decarbonization chemistry utilizing a majority of SrCO3 is investigated. SrCO3 is much more abundant, and an order of magnitude less expensive, than Li2CO3. The equivalent affinities of SrCO3 and Li2CO3 for absorbing and releasing CO2 are demonstrated to be comparable, and are unlike all the other alkali and alkali earth carbonates. The temperature domain in which the CO2 transformation to GNCs can be effective is <800 °C. Although the solidus temperature of SrCO3 is 1494 °C, it is remarkably soluble in Li2CO3 at temperatures less than 800 °C, and the electrolysis energy is low. High purity CNTs are synthesized from CO2 respectively in SrCO3 based electrolytes containing 30% or less Li2CO3.

Advanced Queueing and Location-Allocation Strategies for Sustainable Food Supply Chain

Background: This study presents an integrated multi-product, multi-period queuing location-allocation model for a sustainable, three-level food supply chain involving farmlands, facilities, and markets. The model employs M/M/C/K queuing systems to optimize the transportation of goods, enhancing efficiency and sustainability. A mixed-integer nonlinear programming (MINLP) approach is used to identify optimal facility locations while maximizing profitability, minimizing driver waiting times, and reducing environmental impact. Methods: The grasshopper optimization algorithm (GOA), a meta-heuristic algorithm inspired by the behavior of grasshopper swarms, is utilized to solve the model on a large scale. Numerical experiments demonstrate the effectiveness of the proposed model, particularly in solving large-scale problems where traditional methods like GAMS fall short. Results: The results indicate that the proposed model, utilizing the grasshopper optimization algorithm (GOA), effectively addresses complex and large-scale food supply chain problems. Compared to GAMS, GOA achieved similar outcomes with minimal differences in key metrics such as profitability (with a gap ranging from 0.097% to 1.11%), environmental impact (0.172% to 1.83%), and waiting time (less than 0.027%). In large-scale scenarios, GOA significantly reduced processing times, ranging from 20.45 to 64.78 s. The optimization of processing facility locations within the supply chain, based on this model, led to improved balance between cost (up to $74.2 million), environmental impact (122,112 hazardous units), and waiting time (down to 11.75 h). Sensitivity analysis further demonstrated that increases in truck arrival rates and product value had a significant impact on improving supply chain performance.

Impact of airline social media marketing on purchase intention:Evidence from China using PLS-SEM

Social media has emerged as a pivotal marketing instrument and a platform that facilitates connections between consumers and businesses. In the intense market competition among peer airlines and high-speed rail services, the effective and efficient use of social media can provide a competitive edge for airlines in China. This paper constructs a partial least squares structural equation modelling (PLS-SEM) and examines the impact of the perceived ease of use of the social media platform, perceived usefulness of information, and marketing strategies on customer perceived value and purchase intention for Chinese airlines using multigroup analysis. The results suggest that social media marketing can positively influence on customers’ purchase intention, and perceived value plays a mediating role between social media marketing and customers’ purchase intention. Perceived usefulness of information is the most important factor contributing to the perceived value of airline products while marketing strategy is the most significant factor that can increase purchase intention. The research indicates a clear need to tailor marketing strategies for passengers based on factors such as gender, income, social media usage, and travel frequency.

Value and economic impact of fuel subsidies on the Mexican fishing industry

ABSTRACT Fuel is an important input in the fishing industry’s activities, and fuel subsidies are aimed at generating more competitiveness and encouraging development. Nevertheless, they can also create incentives for fishers to exert more effort, thereby resulting in overexploitation. This paper estimates the economic value of fuel used by the Mexican fishing industry based on the elasticity of production with respect to fuel (εC) and the value of the marginal product (ρC) through the Cobb-Douglas and Trans-Log production function. The εC and ρC were estimated to be 0.52 and USD 3.1, respectively, with the latter contributing to only 8.3% of the fuel subsidy. Furthermore, a direct relationship is evident when observing the trends and the differences in means of the average price of fishery landings and the number of subsidies between 2011 and 2019. That is, the higher the prices and/or subsidies, the higher the levels of extraction. These results have important implications for fuel management and its relationship with the extraction of fishery resources, especially in countries where a subsidy policy is applied in an attempt to support the sector, but which at the same time can have a negative impact on fishery resources.

399 Effect of feeding palm oil products on finishing cattle performance, carcass characteristics, and methane production

Abstract The objectives of this experiment were to evaluate feeding palm oil products on feedlot cattle performance and methane production. Steers (n = 320; 380 ± 14.5 kg) were allocated to 40 pens in a randomized block design and assigned to 1 of 5 treatments consisting of different sources of supplemental fat: 1) No Oil; negative control containing 0.0% supplemental fat, 2) Corn Oil; positive control containing 4.0% supplemental corn oil, 3) Whole Palm; 4.0% supplemental whole palm oil, 4) Olein; 4.0% supplemental palm olein oil, or 5) Stearin; 4.0% supplemental palm stearin oil. Cattle consuming Corn Oil, Olein and Stearin all had greater (P = 0.04) final body weight (BW) and hot carcass weight (HCW) than cattle consuming no oil but were not different (P &amp;gt; 0.11) from each other or from Whole Palm, which was intermediate. Dry matter intake (DMI) of cattle consuming No Oil, Whole Palm and Stearin oil was not different from each other; however, cattle fed Corn Oil had greater intake than Whole Palm (P = 0.03). Corn Oil, Olein, and Stearin all had greater average daily gain (ADG) than cattle consuming No Oil (P = 0.04) but were not different (P &amp;gt; 0.12) from Whole Palm. Adding fat improved feed efficiency (gain to feed; G:F) as all diets including added fat had greater (P &amp;lt; 0.01) G:F than No Oil. Marbling scores were greater (P = 0.01) for Olein and Stearin than Corn and Whole Palm. There were no differences in backfat, ribeye area or liver abscess rate among any treatments (P &amp;gt; 0.74). Gas emissions were evaluated for only the No Oil and Whole Palm treatments. Total methane and methane produced per pound of dry matter intake was less for cattle consuming Whole Palm than No Oil by 14.8% (P &amp;lt; 0.04) while cattle were in the methane chamber. Methane produced per kilogram of ADG for Whole Palm was also reduced (P &amp;lt; 0.01) by 21.4% compared with No Oil. The results of this study indicate feeding palm oil products as a source of supplemental fat in finishing diets increases final BW, ADG, and HCW compared with feeding no supplemental fat, but had minimal impact on DMI resulting in an improvement in G:F. Adding supplemental fat reduced methane emissions in cattle when feeding Whole Palm compared with No Oil. The value of palm oil products in feedlot finishing diets is comparable with feeding corn oil.

Administration or marketization: Environmental regulation, marketization and agricultural green total factor productivity

The mature market can effectively reflect the value of green agricultural products, but the market in developing countries is developing slowly, so how to implement administrative environmental policies while cultivating the market has become the key to the green development of agriculture. In this paper, the government and the market are discussed under the common goal of agricultural green development. Based on the provincial panel data of China, taking agricultural green total factor productivity (AGTFP) as a breakthrough point, the relationship between environmental regulation tools, marketization processes and agricultural green development, specific applicable conditions and transmission mechanisms are explored, and further subdivided into factor and product markets to verify their correlation with AGTFP. The results show that environmental regulation and marketization processes and AGTFP are positively correlated. The former can establish a positive relationship with AGTFP through resource reallocation and technological innovation, and the latter can do so by improving the level of information and land transfer and perfecting infrastructure construction. These findings will provide new ideas for developing countries similar to China's agricultural development and enlighten developing countries pay full attention to and cultivate the market while formulating appropriate environmental regulation policies. In addition, they also need to coordinate the development of technology and organizations.
