How do we age? A decomposition of Gompertz law Open
A strong regularity of human life is Gompertz's law, which predicts a near-perfect exponential increase in mortality with age. In this paper, we take into account that chronological age is not a cause of death and decompose Gompertz's law …

Physiological aging and life-cycle labor supply across countries Open
We construct a cohort-based frailty index for 180 countries over the period 1990-2019. We use this measure of physiological aging to estimate the impact of deteriorating health on labor force participation. Our three-dimensional panel fram…

Physiological aging around the World Open
We extract data on physiological aging by computing a frailty index for 201 countries over the period 1990–2019. Using panel estimation techniques, we show that the macro frailty index replicates basic regularities previously observed in r…

The Effect of Immigration on Local Labor Markets: Lessons from the 1920s Border Closure Open
In the 1920s, the United States substantially reduced immigration by imposing country-specific entry quotas. We compare local labor markets differentially exposed to the quotas due to variation in the national origin mix of their immigrant…

DeepTimeAnomalyViz: A Tool for Visualizing and Post-processing Deep Learning Anomaly Detection Results for Industrial Time-Series Open
Industrial processes are monitored by a large number of various sensors that produce time-series data. Deep Learning offers a possibility to create anomaly detection methods that can aid in preventing malfunctions and increasing efficiency…

Representation Learning for Efficient and Effective Similarity Search and Recommendation Open
How data is represented and operationalized is critical for building computational solutions that are both effective and efficient. A common approach is to represent data objects as binary vectors, denoted \textit{hash codes}, which requir…

The 1918 epidemic and a V‐shaped recession: evidence from historical tax records* Open
We exploit high‐quality vital statistics data and annual income data, obtained from historical municipality tax records, to study the economic aftermath of the 1918 influenza epidemic in Denmark. We find that average income followed a V‐sh…

Detecting Faults during Automatic Screwdriving: A Dataset and Use Case of Anomaly Detection for Automatic Screwdriving Open
Detecting faults in manufacturing applications can be difficult, especially if each fault model is to be engineered by hand. Data-driven approaches, using Machine Learning (ML) for detecting faults have recently gained increasing interest,…

Fetal origins—A life cycle model of health and aging from conception to death Open
The fetal origins hypothesis suggests that health and nutrition shocks in utero are causally related to health deficits in old age. It has received considerable empirical support, both within epidemiology and economics but so far it has no…

AURSAD: Universal Robot Screwdriving Anomaly Detection Dataset Open
Screwdriving is one of the most popular industrial processes. As such, it is increasingly common to automate that procedure by using various robots. Even though the automation increases the efficiency of the screwdriving process, if the pr…

Automatic Fake News Detection: Are Models Learning to Reason? Open
Most fact checking models for automatic fake news detection are based on reasoning: given a claim with associated evidence, the models aim to estimate the claim veracity based on the supporting or refuting content within the evidence. When…
