THE URBANOLOGISTS COME TO TOWN: Professional Life and Work in the Urban Solutions Industry

International Journal of Urban and Regional Research, EarlyView.
Abstract This article charts the upsurge of an eclectic global community of professionals new to the field of urban policy and governance, animated by playful and celebratory attitudes towards cities and urbanization: the urbanologists. It contributes to debates in critical urban theory and critical ethnographies of technology to problematize ...

Modelling and Understanding of Chatter [PDF]

Recent analysis in chatter modelling of BTA deep-hole drilling consisted in phenomenological modelisation of relationships between the observed time series and appearance of chatter during the process. Using the newly developed MEWMA control chart [4, 5],

PLACE‐FRAMING URBANITY: The Case of Kalasatama, Helsinki

International Journal of Urban and Regional Research, EarlyView.
Abstract Narratives, visuality and symbolic representations are increasingly important in contemporary urban planning and development. This article seeks to understand how urbanity, one of the key goals of Helsinki's recent planning, has been constructed in the Kalasatama regeneration area. The construction of urban image and identity is viewed as soft

Glucagon‐like peptide‐1 receptor agonist use and violent crime among US adults

Criminology, EarlyView.
Abstract Glucagon‐like peptide‐1 receptor agonists (GLP‐1 RAs), a class of medications widely prescribed for diabetes and obesity, have exhibited emerging effects on substance use, reward processing, and impulse control. This study examines whether current GLP‐1 RA use moderates established behavioral pathways to violent crime from impulsivity and ...

Comparative Genomics and Functional Evidence for Convergent Adaptation to Hypoxia in Mammals

Integrative Zoology, EarlyView.
This study reveals convergent selection in mammals adapted to hypoxia. Functional assays demonstrate that amino acid mutations reduce oxidative stress, attenuate hypoxia‐induced injury, and modulate the hypoxia‐inducible transcription factor (HIF)‐driven hypoxic response.

Surface roughness variation of thin wall milling, related to modal interactions [PDF]

, 2008
High-speed milling operations of thin walls are often limited by the so-called regenerative effect that causes poor surface finish. The aim of this paper is to examine the link between chatter instability and surface roughness evolution for thin wall ...

Generation of chatter marks in surface grinding by using horizontal spindle-reciprocating table type machines.

Journal of the Japan Society of Precision Engineering, 1985
In order to clarify the mechanism of chatter mark generation in surface grinding by using horizontal spindle-reciprocating table type machines, experiments are conducted to measure the relative displacements between a grinding wheel head and a work table during various grinding operations, the dynamic characteristics of the surface grinding machines ...

Gut Microbiota Analysis and Comparison in Forest Musk Deer (Moschus berezovskii) of Different Ages and Musk‐Secreting Periods

Integrative Zoology, EarlyView.
Metagenomic sequencing was used to analyze fecal microbiota of captive male forest musk deer (FMD) from the Sichuan Institute of Musk Deer Breeding across ages and musk‐secreting periods. Gut microbiota was generally stable and dominated by Firmicutes, while age and musk secretion shaped microbial composition and function, with musk collection linked ...
