Solving Challenging Math Word Problems Using GPT-4 Code Interpreter with Code-based Self-Verification

Recent progress in large language models (LLMs) like GPT-4 and PaLM-2 has brought significant advancements in addressing math reasoning problems. In particular, OpenAI's latest version of GPT-4, known as GPT-4 Code Interpreter, shows remarkable performance on challenging math datasets. In this paper, we explore the effect of code on enhancing LLMs' reasoning capability by introducing different constraints on the \textit{Code Usage Frequency} of GPT-4 Code Interpreter. We found that its success can be largely attributed to its powerful skills in generating and executing code, evaluating the output of code execution, and rectifying its solution when receiving unreasonable outputs. Based on this insight, we propose a novel and effective prompting method, explicit \uline{c}ode-based \uline{s}elf-\uline{v}erification~(CSV), to further boost the mathematical reasoning potential of GPT-4 Code Interpreter. This method employs a zero-shot prompt on GPT-4 Code Interpreter to encourage it to use code to self-verify its answers. In instances where the verification state registers as ``False'', the model shall automatically amend its solution, analogous to our approach of rectifying errors during a mathematics examination. Furthermore, we recognize that the states of the verification result indicate the confidence of a solution, which can improve the effectiveness of majority voting. With GPT-4 Code Interpreter and CSV, we achieve an impressive zero-shot accuracy on MATH dataset \textbf{(53.9\% $\to$ 84.3\%)}.Comment: Solving Challenging Math Word Problems Using GPT-4 Code Interpreter with Code-based Self-Verificatio

A lymphocyte-microglia-astrocyte axis in chronic active multiple sclerosis

Multiple sclerosis (MS) lesions that do not resolve in the months after they form harbour ongoing demyelination and axon degeneration, and are identifiable in vivo by their paramagnetic rims on MRI scans(1-3). Here, to define mechanisms underlying this disabling, progressive neurodegenerative state(4-6) and foster development of new therapeutic agents, we used MRI-informed single-nucleus RNA sequencing to profile the edge of demyelinated white matter lesions at various stages of inflammation. We uncovered notable glial and immune cell diversity, especially at the chronically inflamed lesion edge. We define \u27microglia inflamed in MS\u27 (MIMS) and \u27astrocytes inflamed in MS\u27, glial phenotypes that demonstrate neurodegenerative programming. The MIMS transcriptional profile overlaps with that of microglia in other neurodegenerative diseases, suggesting that primary and secondary neurodegeneration share common mechanisms and could benefit from similar therapeutic approaches. We identify complement component 1q (C1q) as a critical mediator of MIMS activation, validated immunohistochemically in MS tissue, genetically by microglia-specific C1q ablation in mice with experimental autoimmune encephalomyelitis, and therapeutically by treating chronic experimental autoimmune encephalomyelitis with C1q blockade. C1q inhibition is a potential therapeutic avenue to address chronic white matter inflammation, which could be monitored by longitudinal assessment of its dynamic biomarker, paramagnetic rim lesions, using advanced MRI methods

Zn-doped Sb70Se30 thin films with multiple phase transition for high storage density and low power consumption phase change memory applications

The single layer Zn44Sb39Se17 thin film, being fabricated by Sb70Se30 and Zn using co-sputtering method, exhibits double phase change transition. The double phase change processes are mainly attributed to the crystallization of the Sb and ZnSb phases. The potential operating temperature for ten years of two phase change processes are 64 degrees C and 179 degrees C, of which the good stability of the second phase change can be sufficient for the autoelectronic applications. Meanwhile we also discovered the Zn44Sb39Se17 thin film presents apparent low power consumption in comparison with Ge2Sb2Te5 and other reported Sb-Se based phase change materials.

Improved thermal stability and fast phase change speed of Y-doped Sb7Se3 thin film for phase change memory applications

By combining experiments and first-principles calculations, Y-doped Sb7Se3 thin films were successfully fabricated and investigated. Our results suggest that Y is one promising dopant for simultaneously enhancing thermal stability, increasing phase change speed and reducing power of consumption. In particular, the temperature of ten year data retention for Y-doped Sb7Se3 thin film increases to 118.5 degrees C. The fast phase change speed (10 ns) can be realized for Y-doped Sb7Se3 thin film, which is fairly competitive with that of traditional GST (100 ns). Theoretical calculations suggest the electrical conductivity can be reduced by Y doping, which might be one underlying reason for low power consumption. Furthermore, it is found that Y also shows an advantageous role in tuning the band structure and triggering the indirect to direct band gap transition in Sb-Se system, which is of great importance for the design of optoelectronic devices. Thus, our work indicates the important role of Y dopant in Sb-Se system for both phase change memory and other semiconductor devices

Downregulation of YAP Activity Restricts P53 Hyperactivation to Promote Cell Survival in Confinement

Abstract Cell migration through confining three dimensional (3D) topographies can lead to loss of nuclear envelope integrity, DNA damage, and genomic instability. Despite these detrimental phenomena, cells transiently exposed to confinement do not usually die. Whether this is also true for cells subjected to long‐term confinement remains unclear at present. To investigate this, photopatterning and microfluidics are employed to fabricate a high‐throughput device that circumvents limitations of previous cell confinement models and enables prolonged culture of single cells in microchannels with physiologically relevant length scales. The results of this study show that continuous exposure to tight confinement can trigger frequent nuclear envelope rupture events, which in turn promote P53 activation and cell apoptosis. Migrating cells eventually adapt to confinement and evade cell death by downregulating YAP activity. Reduced YAP activity, which is the consequence of confinement‐induced YAP1/2 translocation to the cytoplasm, suppresses the incidence of nuclear envelope rupture and abolishes P53‐mediated cell death. Cumulatively, this work establishes advanced, high‐throughput biomimetic models for better understanding cell behavior in health and disease, and underscores the critical role of topographical cues and mechanotransduction pathways in the regulation of cell life and death

Context effects and behaviour change techniques in randomised trials: a systematic review using the example of trials to increase adherence to physical activity in musculoskeletal pain

OBJECTIVE:To describe and explore the effects of contextual and behaviour change technique (BCT) content of control and target interventions in clinical trials.DESIGN:Review and meta-analysis of 42 trials from a Cochrane review of physical activity in chronic musculoskeletal pain.MAIN OUTCOME MEASURES:Two researchers coded descriptions of target and control interventions for (a) 93 BCTs and (b) whether target and control interventions shared each of five contextual features (practitioners' characteristics, patient-practitioner relationship, intervention credibility, superficial treatment characteristics e.g. delivery modality, and environment). Quality of study reporting was assessed. Effect sizes for adherence to physical activity and class attendance were computed (Cohen's d) and analysed separately.RESULTS:For physical activity outcomes, after controlling for reporting quality, larger effect sizes were associated with target and control interventions using different modalities (? = -.34, p = .030), target and control interventions involving equivalent patient-practitioner relationship (? = .40, p = .002), and target interventions having more unique BCTs (i.e. more BCTs not also in the control) (? = .008, p = .030). There were no significant effect moderators for class attendance outcomes.CONCLUSION:Contents of control conditions can influence effect sizes and should be considered carefully in trial design and systematic reviews
