Dynamical Control Enables The Formation Of Demixed Biomolecular Condensates, Andrew Z Lin, Kiersten M Ruff, Furqan Dar, Ameya Jalihal, Matthew R King, Jared M Lalmansingh, Ammon E Posey, Nadia A Erkamp, Ian Seim, Amy S Gladfelter, Rohit V Pappu

2020-Current year OA Pubs

Cellular matter can be organized into compositionally distinct biomolecular condensates. For example, in Ashbya gossypii, the RNA-binding protein Whi3 forms distinct condensates with different RNA molecules. Using criteria derived from a physical framework for explaining how compositionally distinct condensates can form spontaneously via thermodynamic considerations, we find that condensates in vitro form mainly via heterotypic interactions in binary mixtures of Whi3 and RNA. However, within these condensates, RNA molecules become dynamically arrested. As a result, in ternary systems, simultaneous additions of Whi3 and pairs of distinct RNA molecules lead to well-mixed condensates, whereas delayed addition of an RNA component results …

Lattice Investigations Of The Chimera Baryon Spectrum In The Sp(4) Gauge Theory, Ed Bennett, Deog Ki Hong, Ho Hsiao, Jong-Wan Lee, C. -J. David Lin, Biagio Lucini, Maurizio Piai, Davide Vadacchino

School of Engineering, Computing and Mathematics

We report the results of lattice numerical studies of the Sp(4) gauge theory coupled to fermions (hyperquarks) transforming in the fundamental and two-index antisymmetric representations of the gauge group. This strongly-coupled theory is the minimal candidate for the ultraviolet completion of composite Higgs models that facilitate the mechanism of partial compositeness for generating the top-quark mass. We measure the spectrum of the low-lying, half-integer spin, bound states composed of two fundamental and one antisymmetric hyperquarks, dubbed chimera baryons, in the quenched approximation. In this first systematic, non-perturbative study, we focus on the three lightest parity-even chimera-baryon states, in analogy with …

Unethical Marketing And Advertising To Children: Need For Regulation, Dr Sheetal Kapoor, Vikas Trivedi

International Journal on Consumer Law and Practice

The International Organization for Standardization (ISO) lays emphasis to regulate advertising targeted at children globally as kids are inexperienced and vulnerable to adverse impact of promotions by marketers and such regulations are trailing behind.1 Ensuring a robust regulatory mechanism and its effective enforcement remains the biggest challenge globally. The present paper studies the rationale of advertisements targeting children, assesses the impact of contemporary media advertisements on children and appraises the existing regulatory landscape of children targeted advertisements in India. It pushes for the need for stronger regulatory framework in the emerging markets.

Is Right To Repair One’S Own Good A Consumer Right? An Analysis Of The Changing Dimensions Of Consumer Rights In India., Tr Subramanya, Nidhi Saroj

International Journal on Consumer Law and Practice

The “Right to Repair” is a novel and non - traditional legal concept that addresses granting of the right to fix a damaged product, such as a car or smartphone, or to make any changes to such a device by the owner, the maker, or a third-party repair store. A growing global movement, the “right to repair” promotes consumers’ independence by allowing them to perform maintenance and repairs on their own equipment rather than being limited to the manufacturer’s service options. Countries throughout the world including United States and the United Kingdom have enacted laws by way of protecting citizens’ …

Navigating Unfair Contract Terms: Drawing Insights From Australia In Addressing The Legal Conundrum In Malaysia, Ibtisam@Ilyana Ilias, Norazlina Abdul Aziz, Hariz Sufi Zahari, Helza Nova Lita

International Journal on Consumer Law and Practice

In Malaysia, the regulation of unfair contract terms within business-to-consumer contracts falls under the jurisdiction of Part IIIA of the Consumer Protection Act 1999. This regulatory framework is overseen by the Ministry of Domestic Trade and Living Cost. However, the effectiveness of Part IIIA is hindered by certain gaps, resulting in its infrequent utilization for determining unfair terms in consumer contracts. One of the primary challenges lies in interpreting key terms such as “harsh,” “oppressive,” “unconscionable,” and “adequate justification.” These ambiguities often remain unresolved until legal proceedings take place. Complicating matters, doubts persist regarding the applicability of the Consumer Protection …

The Economics Of Repair: Fixing Planned Obsolescence By Activating The Right To Repair In India, Dunia Zongwe, Mahantesh Gs, Mamatha R

International Journal on Consumer Law and Practice

This paper examines the lack of a Right to Repair (R2R) legislation in India, particularly in the technology sector, and proposes key principles for an optimal Right to Repair Act based on competition economics and consumer choice. In the current scenario, electronic devices are often designed with planned obsolescence, leading to limited lifespans and encouraging a cycle of consumption and disposal, which negatively impacts the economy, society, and the environment. The global R2R campaign aims to balance societal rights and corporate interests by empowering consumers with the right to repair their devices.

Our research is the first to develop core …

Consumer Harms Arising From The Competition Dynamic Of E-Commerce Platforms In Malaysia, Tze Chin Ong Dr, Mei Fei Lee Ms., Norhoneydayati Abdul Manap, Zalina Abdul Halim Dr., Sridevi Thambapillay

International Journal on Consumer Law and Practice

The structure of the digital market of e-commerce platforms is dynamic, with a combination of characteristics such as strong network effects, concentrated multi-sided platforms, extreme economies of scale and scope, low marginal costs, and high data returns. These strong network externalities within the multisided e-commerce market make the competitive environment in e-commerce significantly different from the conventional monogamous market as they create gatekeeper positions favouring a few incumbent e-commerce platforms. In these circumstances, gatekeeper incumbent e-commerce platforms often set commercial conditions that have the effect of undermining other players and potential rivals within the ecosystem. In this regard, there has …
