Additionally, the research assessed antinutritional properties and employed UPLC to identify and quantify phenolic compounds in E. latifolia. …

Toward Circular Economy: Potentials Of Spent Coffee Grounds In Bioproducts And Chemical Production, Hisham Ahmed, Rasaq S. Abolore, Swarna Jaiswal, Amit K. Jaiswal

Articles

With growing concern over environmental sustainability and dwindling fossil resources, it is crucial to prioritise the development of alternative feedstocks to replace fossil resources. Spent coffee grounds (SCGs) are an environmental burden with an estimated six million tons being generated on a wet basis annually, globally. SCGs are rich in cellulose, lignin, protein, lipids, polyphenols and other bioactive compounds which are important raw materials for use in industries including pharmaceuticals and cosmetics. Furthermore, the energy sector has the potential to capitalize on the high calorific value of SCGs for biofuel and biogas production, offering a sustainable alternative to fossil fuels. …

Protease Hydrolysed Brewers' Spent Grain Bioactive Extracts For Applications In Human Health, Azza Silotry Naik, Mila Brugiere, Kevin Dunne, Michael Sorohan, Laura Grasa, Bilal Javed

Articles

About 39 million tons of Brewer's spent grain (BSG), the main by-product of beer manufacturing, are produced annually and is used for low value applications. To valorise this rich bioresource, the present work entails bioprocessing of BSG with various proteases (Novozymes) at two different concentrations (4% and 9%) to solubilise protein, carbohydrate and polyphenols from the grain and evaluate its effect on gut and brain health. The results show the highest (p < 0.05) FRAP (Ferric Reducing Antioxidant Power) based antioxidant activity was obtained for Pro 5 (4%: 108.10 ± 4.17 µmole Trolox Equivalence (TE)/g protein, 18.06 ± 0.70 µmole TE/g d.w., which was 3.6 times higher than untreated control extracts. The highest DPPH (1,1-diphenyl-2-picrylhydrazyl) scavenging activity was obtained for the same extract (Pro 5 at 4%: 0.118 ± 0.006 µg AAE/mg d.w., 9%: 0.110 ± 0.006 µg AAE/mg d.w). Proximate composition showed this extract to contain the highest concentration of proteins at 21.66% ± 2.71, and color analysis showed the same Pro 5 (4%) extract to be the darkest (L*53.73) indicating the possible presence of dark polyphenols. Anticancer screening showed Control and Pro 1 to possess cytotoxic effect against colon cancer cells with IC50 of 3.2 and 13.91 mg/mL, respectively. No significant activity was noted against the brain cancer cell line. Thus anti-colon cancer activity of BSG extracts highlights its potential in gut health. The observed bioactivity resulted from a combination of peptides, carbohydrates and polyphenolic compounds in the extract and warrants further characterisation for targeted nutraceutical applications.

Articles

Background: ChatGPT, a chatbot based on a large language model, captured global attention toward the end of 2022. With its potential to generate comprehensive texts of a variety of genres based on a string of straightforward prompts, it was soon perceived as a threat by many in various fields, including – and in particular – education. Schools across the world began banning its use as instructors started to receive suspiciously well-written essays and assignments from their students.

Aim: This study aimed to investigate the prevalence of use of ChatGPT among university students for written assignments, explore the ways students utilize …

Pricing Corporate Governance, Albert Choi

Articles

Scholars and practitioners have long theorized that by penalizing firms with unattractive governance features, the stock market incentivizes firms to adopt the optimal governance structure at their initial public offerings (IPOs). This theory, however, does not seem to match with practice. Not only do many IPO firms offer putatively suboptimal governance arrangements, such as staggered boards and dual-class structures, but these arrangements have been gaining popularity among IPO firms. This Article argues that the IPO market is unlikely to provide the necessary discipline to incentivize companies to adopt the optimal governance package. In particular, when the optimal governance package differs …

Could Moore Have Been Mooted?, Reuven S. Avi-Yonah

Articles

On December 5 the Supreme Court heard oral arguments in Moore, the first constitutional challenge to an income tax provision to come before the Court in more than a century. The issue is whether the word "income" in the 16th Amendment includes a requirement that the income be realized, as implied by some statements in the previous constitutional challenge to an income tax provision considered by the Court, Eisner v. Macomber.

Advances In Diagnostic Tools And Therapeutic Approaches For Gliomas: A Comprehensive Review, Gayathree Thenuwara Nanolab Research Centre, James Curtin, Furong Tian Nanolab Research Centre

Articles

Gliomas, a prevalent category of primary malignant brain tumors, pose formidable clinical challenges due to their invasive nature and limited treatment options. The current therapeutic landscape for gliomas is constrained by a “one-size-fits-all” paradigm, significantly restricting treatment efficacy. Despite the implementation of multimodal therapeutic strategies, survival rates remain disheartening. The conventional treatment approach, involving surgical resection, radiation, and chemotherapy, grapples with substantial limitations, particularly in addressing the invasive nature of gliomas. Conventional diagnostic tools, including computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET), play pivotal roles in outlining tumor characteristics. However, they face limitations, such as …

Relative Effectiveness Of A Radionuclide (210pb), Surface Elevation Table (Set), And Lidar At Monitoring Mangrove Forest Surface Elevation Change, Richard Mackenzie, Ken Krauss, Nicole Cormier, Eugene Eperiam, Jan Van Aardt, Ali Rouzbeh-Kargar, Jessica Grow, Val Klump

Articles

Sea-level rise (SLR) is one of the greatest future threats to mangrove forests. Mangroves have kept up with or paced past SLR by maintaining their forest floor elevation relative to sea level through root growth, sedimentation, and peat development. Monitoring surface elevation change (SEC) or accretion rates allows us to understand mangrove response to SLR and prioritizes resilient ecosystems for conservation or vulnerable ecosystems for restoration. We compared three methods to measure SEC and accretion in mangrove forests: 210Pb, surface elevation tables (SETs), and a terrestrial light detection and ranging system (compact biomass LiDAR—CBL). Lead-210 accretion rates were not significantly …

The Structure Of Secondary Copyright Liability, Felix T. Wu

Articles

Secondary copyright liability and secondary patent liability largely parallel each other. And yet, secondary copyright cases are often quite different from secondary patent cases. Whereas most secondary patent infringers act in a way that targets a particular patent or group of related patents, secondary copyright infringement mostly arises in the context of technologies or services that work across all copyrighted works. Secondary copyright liability raises issues of platform liability in ways that secondary patent liability usually does not.

The current structure and framing of secondary copyright liability inadequately account for this distinction. The result is that secondary copyright liability tends …

The Need For Energy Storage On Renewable Energy Generator Outputs To Lessen The Geeth Effect, I.E. Short-Term Variations Mainly Associated With Wind Turbine Active Power Output, Tony Kealy

Articles

Many studies investigating the short-term variations associated with the power output from wind turbine generators utilise simulated or modelled data in the analysis. This current study uses short-term empirical data downloaded directly from operational wind turbines via electrical power quality meters. The empirical data shows that the short-term variations (one-second or sub-one-second timeframe) occur continuously over most of the power output range. A novel name is proposed, the Geeth Effect, for this variability phenomenon. The Geeth Effect is measured using the coefficient of variation mathematical expression and is likely contributing to (i) lower-than-expected financial and environmental benefits associated with …

Exploring The Impact Of Signal Quality Enhancement On Heart Sound Classification Models, Davoud Shariat Panah, Andrew Hines, Susan Mckeever

Articles

Limited cardiology resources increase the urgency for automated heart disease screening for the general public. Heart sound diagnostic models have been recently employed as a cost-effective solution for the initial screening of heart disease. Noise in heart sound recordings, however, can reduce the performance of such data-driven models. Various quality enhancement approaches have been adopted to alleviate the destructive impact of noise on model performance. One approach is universal noise reduction which applies denoising techniques to recordings, irrespective of their noise level. The second approach is targeted noise reduction, which applies denoising solely to recordings deemed to need it, based …

Renormalized Stress-Energy Tensor For Scalar Fields In Hartle-Hawking, Boulware, And Unruh States In The Reissner-Nordström Spacetime, Julio Arrechea, Cormac Breen, Adrian Ottewill, Peter Taylor

Articles

In this paper, we consider a quantum scalar field propagating on the Reissner-Nordström black hole spacetime. We compute the renormalized stress-energy tensor for the field in the Hartle-Hawking, Boulware and Unruh states. When the field is in the Hartle-Hawking state, we renormalize using the recently developed “extended coordinate” prescription. This method, which relies on Euclidean techniques, is very fast and accurate. Once, we have renormalized in the Hartle-Hawking state, we compute the stress-energy tensor in the Boulware and Unruh states by leveraging the fact that the difference between stress-energy tensors in different quantum states is already finite. We consider a …

Raman Spectroscopic Analysis Of Human Serum Samples Of Convalescing Covid-19 Positive Patients, Hugh Byrne, Naomi Jackson, Jaythoon Hassan

Articles

Rapid screening, detection and monitoring of viral infection is of critical importance, as exemplified by the rapid spread of SARS-CoV-2, leading to the worldwide pandemic of COVID-19. This is equally the case for the stages of patient convalescence as for the initial stages of infection, to understand the medium and long terms effects, as well as the efficacy of therapeutic interventions. Optical spectroscopic techniques potentially offer an alternative to currently employed techniques of screening for the presence, or the response to infection. In this study, the ability of Raman spectroscopy to distinguish between samples of the serum of convalescent COVID-19 …

This article explores these issues and highlights the need …

The Future Of Anti-Poverty Legislation, Andrew Hammond, Ariel Jurow Kleiman, Gabriel Scheffler

Articles

The era of big-government COVID relief is over. The initial pandemic relief legislation, followed by two years of Democratic control in Washington, seemed to herald the expansion and modernization of the U.S. safety net. But sustained reform proved elusive. Now that this window of opportunity has closed, it's time to step back and take stock. For those who focus on anti-poverty programs, one question persists: The next time there is such an opportunity to strengthen anti-poverty programs through legislation, how should federal law change?

This Article suggests the answer to that question lies in lessons from recent experience, including, but …

Residual Pulmonary Vascular Obstruction Following Mechanical Thrombectomy For Submassive Pulmonary Embolism: A Single-Center Analysis, Brian Stegman, Thom G. Dahle, Wade Schmidt, Jacob R. Dutcher, Tanya Glenz

Articles

Background:

Residual pulmonary vascular obstruction (RPVO) following pulmonary embolism (PE) is associated with residual dyspnea, recurrent venous thromboembolism, and chronic thromboembolic pulmonary hypertension. Historically, acute PE treated with anticoagulation alone results in high rates of significant RPVO. Contemporary treatment of submassive PE often involves catheter-based interventions, including mechanical thrombectomy (MT), although their relation to RPVO is not characterized. In this study, we aimed to evaluate the rate of greater than or equal to 10% RPVO in patients treated with MT.

Methods:

Twenty consecutive patients with submassive PE in a single center underwent MT and subsequent planar ventilation/perfusion scintigraphy scan at …

Up To Code: Lessons Learned In Evaluating And Improving Legacy Irs, Frances Chang Andreu

Articles

Not all repositories are created under ideal circumstances, and inheriting an institutional repository can present challenges distinct from building one from scratch. Changes in institutional vision, policies, and priorities can lead to inconsistent content and limited metadata. Lack of documentation and loss of institutional memory can result in uncertainty about previous decisions. This case study examines the process of auditing a legacy institutional repository in order to ensure the content best reflects the institution’s current goals and policies.

Feedback Loops: More Valuable Than Money, Patrick Barry

Articles

In an essay called "Secrets of Positive Feedback,” Douglas Conant, the former CEO of Campbell Soup Company, shares a key element of the leadership style that helped him resurrect Campbell’s from financial ruin in 2001 and turn it into both a highly profitable business by the time he stepped down in 2011 and an award-winning, much more inclusive workplace: During his ten years at the helm, he wrote more than 30,000 thank-you notes to his employees and customers.

Vietnam's "Entire People Ownership" Of Land: Theory And Practice, Phan Trung Hien, Hugh D. Spitzer

Articles

The Constitution of Vietnam declares that “[t]he Socialist Republic of Vietnam State is a socialist rule of law State of the People, by the People, and for the People.” It also states that land is “under ownership by the entire people represented and uniformly managed by the State.” This means the entire people of Vietnam are collective landowners and the Vietnam State is their “representative.” Given that, how might the public execute its real ownership—rather than treating “people’s ownership” as just a slogan? This article analyzes the gaps in theory and practice in Vietnam, a country with a robust market …

States’ Duty Under The Federal Elections Clause And A Federal Right To Education, Evan Caminker

Articles

Fifty years ago, in San Antonio Independent School District v. Rodriguez, the Supreme Court failed to address one of the preeminent civil rights issues of our generation—substandard and inequitable public education—by holding that the federal Constitution does not protect a general right to education. The Court didn’t completely close the door on a narrower argument that the Constitution guarantees “an opportunity to acquire the basic minimal skills necessary for the enjoyment of the rights of speech and of full participation in the political process.” Both litigants and scholars have been trying ever since to push that door open, pressing …

Consent Searches And Underestimation Of Compliance: Robustness To Type Of Search, Consequences Of Search, And Demographic Sample, Roseanna Sommers, Vanessa K. Bohns

Articles

Most police searches today are authorized by citizens' consent, rather than probable cause or reasonable suspicion. The main constitutional limitation on so-called “consent searches” is the voluntariness test: whether a reasonable person would have felt free to refuse the officer's request to conduct the search. We investigate whether this legal inquiry is subject to a systematic bias whereby uninvolved decision-makers overstate the voluntariness of consent and underestimate the psychological pressure individuals feel to comply. We find evidence for a robust bias extending to requests, tasks, and populations that have not been examined previously. Across three pre-registered experiments, we approached participants …

Une Histoire Pragmatique Du Politique, William J. Novak, Stephen W. Sawyer

Articles

Comme le montre ce numero, nous ne sommes guere en manque de tentatives recentes de repenser l'histoire du politique. En effet, deux generations d'historiens ont deja produit un grand nombre de nouvelles approches et de perspectives a partir desquelles il est maintenant possible d'etudier l'histoire politique a nouveaux frais. Dans le contexte historiographique americain, nous avons ete temoins d'une serie de nouvelles approches allant de ce que l'on a appele la « nouvelle histoire sociale politique » des annees 1970 a l'effort des sciences sociales pour « repenser l'Etat » (Bringing the State Back In) dans les annees 1980 et …

The Federal Reserve's Mandates, David T. Zaring, Jeffery Y. Zhang

Articles

Solutions to systemic problems such as climate change and racial inequities have eluded policymakers for decades. In searching for creative solutions, some policymakers have recently thought about expanding the Federal Reserve’s core set of macroeconomic mandates to tackle these issues. But there are real questions about whether that can be done from a legal perspective and whether that should be done from a policy perspective.

Relationships Among Development, Growth, Body Size, Reproduction, Aging, And Longevity - Trade-Offs And Pace-Of-Life., Rong Yuan, Erin Hascup, Kevin Hascup, Andrzej Bartke

Articles

Relationships of growth, metabolism, reproduction, and body size to the biological process of aging and longevity have been studied for decades and various unifying "theories of aging" have been proposed to account for the observed associations. In general, fast development, early sexual maturation leading to early reproductive effort, as well as production of many offspring, have been linked to shorter lifespans. The relationship of adult body size to longevity includes a remarkable contrast between the positive correlation in comparisons between different species and the negative correlation seen in comparisons of individuals within the same species. We now propose that longevity …

Making Tradable White Certificates Trustworthy, Anonymous, And Efficient Using Blockchains, Nouman Ashraf, Sachin Sharma, Sheraz Aslam, Khursheed Aurangzeb

Articles

Fossil fuel pollution has contributed to dramatic changes in the Earth’s climate, and this trend will continue as fossil fuels are burned at an ever-increasing rate. Many countries around the world are currently making efforts to reduce greenhouse gas emissions, and one of the methods is the Tradable White Certificate (TWC) mechanism. The mechanism allows organizations to reduce their energy consumption to generate energy savings certificates, and those that achieve greater energy savings can sell their certificates to those that fall short. However, there are some challenges to implementing this mechanism, such as the centralized and costly verification and control …
