Food contact surfaces (FCSs) include all surfaces that may come in contact with the food during production, processing, and packaging. Food processing industries encounter several challenges due to its microbial interaction with the FCSs, such as cross-contamination of pathogenic microorganisms or allergens in food, formation of biofilm, biodeterioration of food contact surface leads to food with reduced shelf-life and quality. A legal EU framework provides the fundamental postulates for the safety and inertness of all Food Contact Materials (FCMs). Legislations have an important role in providing regulatory guidance on the quality assurance systems and verifying their implementation as a means …

Near-Field Propagation Analysis For Vivaldi Antenna Design: Insight Into The Propagation Process For Optimizing The Directivity, Integrity Of Signal Transmission, And Efficiency, Ha Hoang, Matthias John, Patrick Mcevoy, Max Ammann

Articles

Refined optimization of complex curve–linear-shaped radiators, such as traveling-wave Vivaldi antennas, can be achieved by considering simulated near fields to interpret in detail the structural influences of a design. The relationships between the space and time distributions of electromagnetic (EM) energy clusters and the geometric features are revealed with appropriate use of impulse response analysis combined with the multiple signal classification (MUSIC) algorithm. This article reports a deeper approach when applied to the adjustment of the geometric features of a traveling-wave antenna based on an analysis of near-field propagation features.

The diagnosis of prostate cancer is challenging due to the heterogeneity of its presentations, leading to the over diagnosis and treatment of non-clinically important disease. Accurate diagnosis can directly benefit a patient’s quality of life and prognosis. Towards addressing this issue, we present a learning model for the automatic identification of prostate cancer. While many prostate cancer studies have adopted Raman spectroscopy approaches, none have utilised the combination of Raman Chemical Imaging (RCI) and other imaging modalities. This study uses multimodal images formed from stained Digital Histopathology (DP) and unstained RCI. The approach was developed and tested on a set …

Let Knowledge Make Recommendations For You, Zhiixue Jiang, Chengying Chi, Yun Yun Zhan

Articles

The knowledge graph can make more accurate personalized recommendations for the recommendation system, but it is also interpretative and has traces to follow. The purpose of the recommendation system is to recommend a series of unobserved items for users. At present, recommendation systems based on knowledge graphs are mainly implemented in two ways: Embedding-based and path based. Embedding methods usually directly use information from the knowledge graph to enrich the representation of an item or user. Still, it failed to introduce multi-hop relations, and it is challenging to use semantic network information. A path-based recommendation algorithm utilizes the knowledge graph …

Optimisation Of Retrofit Wall Insulation: An Irish Case Study, Rakshit D. Muddu, D M. Gowda, Anthony James Robinson, Aimee Byrne

Articles

Ireland has one of the highest rates of emissions per capita in the world and its residential sector is responsible for approximately 10% of total national CO2 emissions. Therefore, reducing the CO2 emissions in this sector will play a decisive role in achieving EU targets of reducing emissions by 40% by 2030. To better inform decisions regarding retrofit of the existing building stock, this study proposes Optimum Insulation Thicknesses (OIT) for typical walls in 25 regions in Ireland. The calculation of OIT includes annual heat energy expenditure, CO2 emissions, and material payback period. The approach taken is based on Heating …

Nature Based Solution As Flood Protection Strategies: The Case Of Caraha River Park, Brazil, Renata V. De Oliveira Gobetti, Ornella Salimbene, Deborah Panepinto

Articles

Following the road paradigm, many cities, at the beginning of the 20th century, experienced a reckless increase in the number of vehicles on the road causing an unsustainable urban and environmental situation. The origin of the problem surely lies in the occupation of the preserved areas. In many South American states, for example, highways generally ignore the presence of environmental obstacles (such as rivers) as they may cause a “delay in modernization”. As a result, riparian forests are invaded and turned into highways, water beds are channeled and most rivers are contaminated with wastewater. Due to the occupation of green …

The Right To Benefit From Big Data As A Public Resource, Mary D. Fan

Articles

The information that we reveal from interactions online and with electronic devices has massive value—for both private profit and public benefit, such as improving health, safety, and even commute times. Who owns the lucrative big data that we generate through the everyday necessity of interacting with technology? Calls for legal regulation regarding how companies use our data have spurred laws and proposals framed by the predominant lens of individual privacy and the right to control and delete data about oneself. By focusing on individual control over droplets of personal data, the major consumer privacy regimes overlook the important question of …

Articles

This Note discusses the use of Al surveillance in places of public accommodations and its implications for civil rights and antidiscrimination law. Part I documents the extensive Al surveillance employed in areas of public accommodation, where American antidiscrimination laws explicitly provide for elevated protection. Part II uses critical race theory to explore how contemporary antidiscrimination law marries two approaches to antidiscrimination in a way that undercuts its own ability to remedy injustice. Part III reveals how antidiscrimination law fails to address issues implicated by Al surveillance in areas of public accommodations, and Part IV proposes a simple solution: abolish it.

Advisors Or Enablers? Bringing Professional Service Providers Into The Guiding Principles’ Fold, Anita Ramasastry

Articles

After a decade, different businesses adhere to the UN Guiding Principles on Business and Human Rights (UNGPs). Some key commercial entities, however, remain largely outside of the UNGPs universe, including professional service providers (PSPs) who are retained by businesses to provide  expert advice and services. These advisors include lawyers, management consultants, architects and others. Some may have specialized units that provide advice on the UNGPs when retained solely for that purpose. But when asked to provide general commercial legal advice, to design a building, or restructure a business, such advisors do not typically appear to apply the UNGPs, to identify …

Label-Free Screening Of Biochemical Changes In Macrophage-Like Cells Following Mos2 Exposure Using Raman Micro-Spectroscopy, Caroline Moore, Andrew Harvety, Jonathan N. Coleman, Hugh Byrne, Jennifer Mcintyre

Articles

The emergence of large scale production techniques for 2D particulate materials has dramatically increased their applications potential. Understanding the interactions of biological cells with such particulate material is therefore of paramount importance, both for toxicological assessment and potential biomedical applications. Conventional in-vitro cytological assays commonly record only a single colorimetric end-point, and do not provide an in-depth analysis of how such materials are uptaken and processed within cells. To demonstrate its potential as an alternative, label free approach, confocal Raman micro-spectroscopy has been used to profile the cellular response of macrophage-like immune cells as a result of exposure to a …

Atmospheric Pressure Dry Etching Of Polysilicon Layers For Highly Reverse Bias-Stable Topcon Solar Cells, Bishal Kafle, Sebastian Mack, Christopher Teßmann, Sattar Bashardoust, Laurent Clochard, Edward Duffy, Andreas Wolf, Marc Hofmann, Jochen Rentsch

Articles

Single-sided etching (SSE) of a-Si/poly-Si is typically considered a challenge for realizing a cost-efficient TOPCon production sequence, as there is a certain degree of unwanted wrap-around for poly-Si deposition technologies such as low pressure chemical vapor deposition, plasma-enhanced chemical vapor deposition, and atmospheric pressure chemical vapor deposition. To date, alkaline or acidic wet-chemical solutions in either inline or batch configurations are used for this purpose. Herein, an alternative SSE process is proposed using an inline dry etching tool, which applies molecular fluorine as the etching gas under atmospheric pressure conditions. The developed etching process performs complete etching of both as-deposited …

On The Mandelbrot Set For I**2 = ±1 And Imaginary Higgs Fields, Jonathan Blackledge

Articles

We consider the consequence of breaking with a fundamental result in complex analysisby lettingi2=±1wherei=√−1is the basic unit of all imaginary numbers. An analysis of theMandelbrot set for this case shows that a demarcation between a Fractal and a Euclidean object ispossible based oni2=−1andi2= +1, respectively. Further, we consider the transient behaviourassociated with the two cases to produce a range of non-standard sets in which a Fractal geometricstructure is transformed into a Euclidean object. In the case of the Mandelbrot set, the Euclideanobject is a square whose properties are investigate. Coupled with the associated Julia sets and othercomplex plane mappings, this …
