Multi-Level Gas Monitoring : A New Approach in Earthquake Research

Fluid anomalies were often considered as possible precursors before earthquakes. However, fluid properties at the surface can change for a variety of reasons, including environmental changes near the surface, the response of the superficial fluid system to loads associated with the mechanical nucleation of earthquake fractures, or as a result of transients in fluid flow from the depths. A key prob

Effect of intraoperative nerve monitoring on postoperative vocal cord palsy rates after thyroidectomy : European multicentre registry-based study

BACKGROUND: Intraoperative nerve monitoring (IONM) of the recurrent laryngeal nerve (RLN) predicts the risk of vocal cord palsy (VCP). IONM can be used to adapt the surgical strategy in order to prevent bilateral VCP and associated morbidity. Controversial results have been reported in the literature for the effect of IONM on rates of VCP, and large multicentre studies are required for elucidation

A tale of planet formation : From dust to planets

The characterization of exoplanets and their birth protoplanetary disks has enormously advanced in the last decade. Benefitting from that, our global understanding of the planet formation processes has been substantially improved. In this review, we first summarize the cutting-edge states of the exoplanet and disk observations. We further present a comprehensive panoptic view of modern core accret

High-Speed Analog-to-Digital Converters in CMOS

The Analog to Digital (A/D) Converters (ADC) are vital components in high-performance radio devices. In the receiver end, the signal received by the analog front-end can not be directly analyzed by the digital core, thus requiring high-performance ADC circuits acting as bridges connecting the analog and digital domain. These circuits are integrated into Complementary Metal-Oxide-Semiconductor (CMO

Drought legacy affects microbial community trait distributions related to moisture along a savanna‐grassland precipitation gradient

Ecosystem models commonly use stable‐state assumptions to predict responses of soil microbial functions to environmental change. However, past climatic conditions can shape microbial functional responses resulting in a ‘legacy effect’. For instance, exposure to drier conditions in the field may shape how soil microbial communities respond to subsequent drought and drying and rewetting (DRW) event

A 10-bit Split-Capacitor SAR ADC with DAC Imbalance Estimation and Calibration

This paper presents a 10-bit SAR ADC with a sampling rate of 200 MS/s. To reduce area and power consumption, the ADC adopts a split-capacitor DAC, where the gain error is estimated and subsequently removed by means of a PRBS signal injected into the DAC and detected at the ADC output. The ADC has been designed and fabricated in a 22nm FD-SOI CMOS process, and achieves an SNDR of 48.7 dB and an SFD

A Design Method to Minimize the Impact of Bit Conversion Errors in SAR ADCs

This paper analyzes the bit conversion errors in high speed SAR ADCs and proposes a design method to minimize their impact on the ADC performance. By removing the SR latch from the output stage of the differential comparator, while using only one comparator output to generate the differential signals for the internal capacitive DAC, sparkle-code errors are avoided, and conversion errors from a pre

Barycentric Markov processes and stability of stochastic integrators

This thesis consists of four papers that broadly concerns two dierent topics. The rsttopic is so-called barycentric Markov processes. By a barycentric Markov process wemean a process that consists of a point/particle system evolving in (discrete) time,whose evolution depends in some way on the mean value of the current points in thesystem.

Public space as commodity : Social production of the Hong Kong waterfront

Although there has been a long tradition of public space-related land speculation and development, the recent success of the High Line in New York has highlighted the transformative effect carefully designed and curated public spaces can have on the local economy. By prioritising exchange value over use value, governments and developers are exploiting the production of public spaces as a means for

Circular Economy Policy at a Crossroads: Encouraging Durable Products or Enabling Faster Cycling of Short-lived Products?

Non-ownership models, where firms rather than consumers remain product owners, are advocated as a way for firms to prolong product lifetimes and contribute to a more Circular Economy. However, it has been suggested that such models could actually encourage ‘faster cycling’, meaning earlier product replacement and shorter product lifetimes. Within recent policy discussions, product durability to pr

The European Public Prosecutor: Quintessential Supranational Criminal Law?

This article critically examines the claim that EPPO is a proper federal supranational prosecutor. The article observes that the EPPO among policymakers and commentators appears to be a hallmark of the transformation of EU criminal law from an intergovernmental paradigm to a strong federal and supranational polity. The EPPO primarily stands out among other EU agencies by having been conferred with

Big Science, Ethics, and the Scalar Effects of Urban Planning

The urban expansion currently under development around the two materials science facilities MAX IV and European Spallation Source in Lund, Sweden, surrounds two meticulously designed research facilities steered by global demands. The new urban area, together with the research facilities dedicated to science and the development of knowledge, expands the city of Lund onto high-quality agricultural l

Associations of Plasma Phospho-Tau217 Levels with Tau Positron Emission Tomography in Early Alzheimer Disease

Importance: There is an urgent need for inexpensive and minimally invasive blood biomarkers for Alzheimer disease (AD) that could be used to detect early disease changes. Objective: To assess how early in the course of AD plasma levels of tau phosphorylated at threonine 217 (P-tau217) start to change compared with levels of established cerebrospinal fluid (CSF) and positron emission tomography (PE

Investigating the clinico-anatomical dissociation in the behavioral variant of Alzheimer disease

Background: We previously found temporoparietal-predominant atrophy patterns in the behavioral variant of Alzheimer’s disease (bvAD), with relative sparing of frontal regions. Here, we aimed to understand the clinico-anatomical dissociation in bvAD based on alternative neuroimaging markers. Methods: We retrospectively included 150 participants, including 29 bvAD, 28 “typical” amnestic-predominant

Internationella fredsbyrån och Nobels fredspris : Debatter i fredsfrågan på kongresser och i Nobeltal före 1914

In the 19th century, an extensive liberal and Christian international peace movement developed. In 1891, an umbrella organization, the International Peace Bureau (IPB), based in Bern, was formed to coordinate the international peace work that had previously been divided into a number of different national and international federations. This would prove successful. The establishment of a Nobel Priz

Genome-wide association analysis of type 2 diabetes in the EPIC-InterAct study

Type 2 diabetes (T2D) is a global public health challenge. Whilst the advent of genome-wide association studies has identified >400 genetic variants associated with T2D, our understanding of its biological mechanisms and translational insights is still limited. The EPIC-InterAct project, centred in 8 countries in the European Prospective Investigations into Cancer and Nutrition study, is one of th

Association is not prediction : A landscape of confused reporting in diabetes – A systematic review

Aims: Appropriate analysis of big data is fundamental to precision medicine. While statistical analyses often uncover numerous associations, associations themselves do not convey predictive value. Confusion between association and prediction harms clinicians, scientists, and ultimately, the patients. We analyzed published papers in the field of diabetes that refer to “prediction” in their titles.
