3. When Life gives you LLMs, make LLM-ADE: Large Language Models with Adaptive Data Engineering

Author

Subjects
Computer Science - Computational Engineering, Finance, and Science, Computer Science - Artificial Intelligence
Abstract

This paper presents the LLM-ADE framework, a novel methodology for continued pre-training of large language models (LLMs) that addresses the challenges of catastrophic forgetting and double descent. LLM-ADE employs dynamic architectural adjustments, including selective block freezing and expansion, tailored to specific datasets. This strategy enhances model adaptability to new data while preserving previously acquired knowledge. We demonstrate LLM-ADE's effectiveness on the TinyLlama model across various general knowledge benchmarks, showing significant performance improvements without the drawbacks of traditional continuous training methods. This approach promises a more versatile and robust way to keep LLMs current and efficient in real-world applications., Comment: 6 pages, 3 tables and 3 figures

Abstract

With the exponential growth in large language models (LLMs), leveraging their emergent properties for specialized domains like finance merits exploration. However, regulated fields such as finance pose unique constraints, requiring domain-optimized frameworks. We present ConFIRM, an LLM-based conversational financial information retrieval model tailored for query intent classification and knowledge base labeling. ConFIRM comprises two modules: 1) a method to synthesize finance domain-specific question-answer pairs, and 2) evaluation of parameter efficient fine-tuning approaches for the query classification task. We generate a dataset of over 4000 samples, assessing accuracy on a separate test set. ConFIRM achieved over 90% accuracy, essential for regulatory compliance. ConFIRM provides a data-efficient solution to extract precise query intent for financial dialog systems., Comment: 10 pages, 2 figures, 2 tables, 2 appendices

Abstract

Contract scholarship has devoted considerable attention to how contract terms are designed to incentivize parties to fulfill their obligations. Less attention has been paid to the production of contracts and the tradeoffs between using boilerplate terms and designing bespoke provisions. In thick markets everyone uses the standard form despite the known drawbacks of boilerplate. But in thinner markets, such as the private deal M&A world, parties trade off costs and benefits of using standard provisions and customizing clauses. This Article reports on a case study of contract production in the M&A markets. We find evidence of an informal information network that transforms bespoke changes in contract terms into industry-wide standard provisions. This organic coordination structure leads to both market-wide coordination as well as a diversity in this response as individual actors implement bespoke variations of the new standard., INTRODUCTION 1882 I.

Abstract

Different areas of transactional practice, such as M&A or high-yield bonds and sovereign bonds, vary in terms of the degree to which they are afflicted by agency problems. In some areas, clients are actively involved in deal making, and in others they are not present until well after the deal is done. If vulnerability to agency problems differs, and these agency problems impact the quality of contract production, one would expect those differences to appear when comparing contract production across practice areas. This Article compares one feature of contract production--the problems of encrusted and sticky boilerplate--across four different deal types where the degree of agency problems is likely to vary. We find that private equity M&A lawyers, who have the highest degree of client monitoring, innovate in order to repair problems in the deal documents more rapidly than do the other deal types. However, we also find that these private equity M&A contracts have more obsolete and encrusted terms than do corporate or sovereign bonds., CONTENTS INTRODUCTION I. INNOVATIONS AND ENCRUSTATIONS A.

31. Ehrenfest approach to open double-well dynamics

Subjects

Abstract

We consider an Ehrenfest approximation for a particle in a double-well potential in the presence of an external environment schematized as a finite resource heat bath. This allows us to explore how the limitations in the applicability of Ehrenfest dynamics to nonlinear systems are modified in an open system setting. Within this framework, we have identified an environment-induced spontaneous symmetry breaking mechanism, and we argue that the Ehrenfest approximation becomes increasingly valid in the limit of strong coupling to the external reservoir, either in the form of increasing number of oscillators or increasing temperature. The analysis also suggests a rather intuitive picture for the general phenomenon of quantum tunneling and its interplay with classical thermal activation processes, which may be of relevance in physical chemistry, ultracold atom physics, and fast-switching dynamics such as in superconducting digital electronics., Comment: 7 pages, 7 figures

Abstract

During myocardial ischaemia‒reperfusion injury (MIRI), the accumulation of damaged mitochondria could pose serious threats to the heart. The migrasomes, newly discovered mitocytosis‐mediating organelles, selectively remove damaged mitochondria to provide mitochondrial quality control. Here, we utilised low‐intensity pulsed ultrasound (LIPUS) on MIRI mice model and demonstrated that LIPUS reduced the infarcted area and improved cardiac dysfunction. Additionally, we found that LIPUS alleviated MIRI‐induced mitochondrial dysfunction. We provided new evidence that LIPUS mechanical stimulation facilitated damaged mitochondrial excretion via migrasome‐dependent mitocytosis. Inhibition the formation of migrasomes abolished the protective effect of LIPUS on MIRI. Mechanistically, LIPUS induced the formation of migrasomes by evoking the RhoA/Myosin II/F‐actin pathway. Meanwhile, F‐actin activated YAP nuclear translocation to transcriptionally activate the mitochondrial motor protein KIF5B and Drp1, which are indispensable for LIPUS‐induced mitocytosis. These results revealed that LIPUS activates mitocytosis, a migrasome‐dependent mitochondrial quality control mechanism, to protect against MIRI, underlining LIPUS as a safe and potentially non‐invasive treatment for MIRI.

Abstract

Aims CD4+ T cells are activated during inflammatory dilated cardiomyopathy (iDCM) development to induce immunogenic responses that damage the myocardium. Low-intensity pulsed ultrasound (LIPUS), a novel physiotherapy for cardiovascular diseases, has recently been shown to modulate inflammatory responses. However, its efficacy in iDCM remains unknown. Here, we investigated whether LIPUS could improve the severity of iDCM by orchestrating immune responses and explored its therapeutic mechanisms. Methods and results In iDCM mice, LIPUS treatment reduced cardiac remodelling and dysfunction. Additionally, CD4+ T-cell inflammatory responses were suppressed. LIPUS increased Treg cells while decreasing Th17 cells. LIPUS mechanically stimulates endothelial cells, resulting in increased secretion of extracellular vesicles (EVs), which are taken up by CD4+ T cells and alter their differentiation and metabolic patterns. Moreover, EVs selectively loaded with microRNA (miR)-99a are responsible for the therapeutic effects of LIPUS. The hnRNPA2B1 translocation from the nucleus to the cytoplasm and binding to caveolin-1 and miR-99a confirmed the upstream mechanism of miR-99a transport. This complex is loaded into EVs and taken up by CD4+ T cells, which further suppress mTOR and TRIB2 expression to modulate cellular differentiation. Conclusion Our findings revealed that LIPUS uses an EVs-dependent molecular mechanism to protect against iDCM progression. Therefore, LIPUS is a promising new treatment option for iDCM.

34. The Business of Securities Class Action Lawyering.

Abstract

Plaintiffs' lawyers in the United States play a key role in combating corporate fraud. Shareholders who lose money as a result of fraud can file securities class actions to recover their losses, but most shareholders do not have enough money at stake to justify overseeing the cases filed on their behalf. As a result, plaintiffs' lawyers control these cases, deciding which cases to file and how to litigate them. Recognizing the agency costs inherent in this model, the legal system relies on lead plaintiffs and judges to monitor these lawyers and protect the best interests of absent class members. Yet there is remarkably little data on the business of securities class action lawyers, leaving lead plaintiffs and judges to oversee this area without the tools to understand how it works. This Article looks inside the black box of securities class action lawyering to explore the business behind these cases. Our study includes hand-collected data on all securities fraud class actions against public corporations filed between 2005 and 2018, a total of nearly 2500 cases. We find that the business of securities class action lawyering is far more complex than prior scholarship has recognized. Contrary to conventional wisdom, there are not two tiers of plaintiffs' law firms; instead, there are multiple tiers of firms, each with its own client base, litigation patterns, and revenue model. Our study gives lead plaintiffs and judges the data and tools they need to understand these tiers and to compare the performance of the law firms within them. We also examine how these law firms are compensated, finding that judges' fee awards fail to account for the difficulty of cases or the risk of nonrecovery in any systematic way. These fees are crucial to ensuring that law firms pursue the right cases on behalf of shareholders, so we suggest ways that judges can use data to improve fee awards. As we will see, the path to reforming securities class actions starts with understanding the business behind them. [ABSTRACT FROM AUTHOR]

Abstract

Recent work of Pritsker defines and studies an areal version of the Mahler measure. We further explore this function with a particular focus on the case where its value is small, as this is most relevant to Lehmer's conjecture. In this situation, we provide improvements to two inequalities established in Pritsker's original paper.

Abstract

We introduce a collection of polynomials $F_N$, associated to each positive integer $N$, whose divisibility properties yield a reformulation of the Goldbach conjecture. While this reformulation certainly does not lead to a resolution of the conjecture, it does suggest two natural generalizations for which we provide some numerical evidence. As these polynomials $F_N$ are independently interesting, we further explore their basic properties, giving, among other things, asymptotic estimates on the growth of their coefficients.

50. Optimized sympathetic cooling of atomic mixtures via fast adiabatic strategies

Abstract

We discuss fast frictionless cooling techniques in the framework of sympathetic cooling of cold atomic mixtures. It is argued that optimal cooling of an atomic species - in which the deepest quantum degeneracy regime is achieved - may be obtained by means of sympathetic cooling with another species whose trapping frequency is dynamically changed to maintain constancy of the Lewis-Riesenfeld adiabatic invariant. Advantages and limitations of this cooling strategy are discussed, with particular regard to the possibility of cooling Fermi gases to a deeper degenerate regime., Comment: 5 pages, 3 figures
