An empirical study of LLaMA3 quantization: from LLMs to MLLMs.

Vis Intell

December 2024

Department of Information Technology and Electrical Engineering, ETH Zurich, Sternwartstrasse 7, Zürich, Switzerland.

The LLaMA family, a collection of foundation language models ranging from 7B to 65B parameters, has become one of the most powerful open-source large language models (LLMs) and the popular LLM backbone of multi-modal large language models (MLLMs), widely used in computer vision and natural language understanding tasks. In particular, LLaMA3 models have recently been released and have achieved impressive performance in various domains with super-large scale pre-training on over 15T tokens of data. Given the wide application of low-bit quantization for LLMs in resource-constrained scenarios, we explore LLaMA3's capabilities when quantized to low bit-width.

Epileptic spasms (ES) are a unique seizure type typically presenting in the form of infantile epileptic spasms syndrome (IESS) with characteristic hypsarrhythmia on scalp EEG and a preponderance with developmental delay or regression. While pharmacotherapy is the mainstay of treatment, surgical options, including disconnective or resective procedures, are increasingly recognized as viable therapeutic options for recurrent or persistent ES. However, limited data on safety, effectiveness, and prognostic factors hinder informed decision-making regarding surgery indications, timing, and intervention type.

Paediatric cancers, although rare, are the leading cause of disease-related mortality in European children above one year. A key pillar of the European Health Union, Europe's Beating Cancer Plan (EBCP) puts a spotlight on childhood cancer. National Cancer Control Plans (NCCPs) have a key role but did not address childhood cancers sufficiently previously.

High-precision molecular manipulation techniques are used to control the distance between radical molecules on superconductors. Our results show that the molecules can host single electrons with a spin 1/2. By changing the distance between tip and sample, a quantum phase transition from the singlet to doublet ground state can be induced.

Protocol to assess bottlenecks inhibiting the scaling up of evidence-based family planning practices in low-income and middle-income countries using mixed methods.

BMJ Open

December 2024

Department of Sexual and Reproductive Health and Research including UNDP/UNFPA/UNICEF/WHO/World Bank Special Programme of Research, World Health Organization, Geneva, Switzerland.

Introduction: Scaling up evidence-based practices (EBPs) in family planning (FP), as recommended by the WHO, has increasingly been accepted by global health actors as core to their mission, goals and activities. National policies, strategies, guidance, training materials, political commitment and donor support exist in many countries to adopt and scale up a range of EBPs, including postpregnancy FP, task sharing for FP and the promotion of social and behaviour change (SBC) for FP. While there has been some success in implementing these practices, coverage remains inadequate in many countries.

Introduction: The Drugs for Neglected Diseases initiative (DNDi) is committed to maximising the scientific value of the individual participant data (IPD) it has collected during its 20 years of activity and the IPD it will collect in the future, while safeguarding research participants' privacy and their right to know how their data will be processed.

Objective: The objective of this article is to share what DNDi has learnt while working on its commitment to data sharing. It also aims to advance the debate about best practice in the research community to avoid 'IPD sharing paralysis', with a focus on multistakeholder projects involving patients and researchers based in countries with various levels of data privacy regulations and measures.

Introduction: Medical progress has significantly improved the survival rates of very preterm-born infants in recent decades. Nevertheless, these infants are still at increased risk for long-term impairments as compared with term-born infants. While the homecoming of a preterm-born infant is long-awaited and brings relief to families, it also marks the end of intensive monitoring and highly specialised professional care.

Experience, access and utilisation of fertility care for infertile men within the biomedical sector in urban Bangladesh: protocol for a qualitative study.

BMJ Open

December 2024

Department of Sexual and Reproductive Health and Research, Human Reproduction Program, World Health Organization, Geneva, Switzerland.

Introduction: One in six people of reproductive age experience infertility in their lifetime throughout the world, often with devastating consequences. Men are often invisible in infertility research and services, yet masculinity and reproductive agency intersect within social, cultural and religious contexts to shape their experiences of infertility and masculine expression. This study aims to provide insights into the lived experience of male infertility, the availability and access of infertility services for men within the biomedical sector in Bangladesh and the potential willingness of men to use home-based semen testing.

Background: Clinical research has offered many definitions and fragmented perspectives of joint morbidity in haemophilia. As joint damage, pain and mobility impairment can be present without clinical record of persistent bleeding, a person-centric joint morbidity characterisation remained a priority for the haemophilia community, giving rise to the 'problem joint' concept. As diagnosing and managing joint morbidity is critical, the aim of this study was to analyse the holistic burden of problem joints in people with moderate or severe haemophilia A (HA).

The clinical development of novel vaccines, injectable therapeutics, and oral chemoprevention drugs has the potential to deliver significant advancements in the prevention of Plasmodium falciparum malaria. These innovations could support regions in accelerating malaria control, transforming existing intervention packages by supplementing interventions with imperfect effectiveness or offering an entirely new tool. However, to layer new medical tools as part of an existing programme, malaria researchers must come to an agreement on the gaps that currently limit the effectiveness of medical interventions for moderate to low transmission settings.

Purpose: Optimizing fracture reduction quality is key to achieve successful osteosynthesis, especially for epimetaphyseal regions such as the proximal humerus (PH), but can be challenging, partly due to the lack of a clear endpoint. We aimed to develop the prototype for a novel intraoperative C-arm-based aid to facilitate true anatomical reduction of fractures of the PH.

Methods: The proposed method designates the reduced endpoint position of fragments by superimposing the outer boundary of the premorbid bone shape on intraoperative C-arm images, taking the mirrored intact contralateral PH from the preoperative CT scan as a surrogate.

Fluorescence recovery after photobleaching (FRAP) can be employed to investigate membrane lipid mixing of vacuoles in live budding yeast cells and distinguish the fused, hemi-fused or non-fused states of these organelles under physiological conditions. Here, we describe a protocol for labeling the outer and inner leaflets of vacuoles in live cells that allow to detect hemifusion intermediates and, thus, identify components necessary for fusion pore opening.
