Modern Code Review: A Case Study at Google

Employing lightweight, tool-based code review of code changes (aka modern code review) has become the norm for a wide variety of open-source and industrial systems. In this paper, we make an exploratory investigation of modern code review at Google. Google introduced code review early on and evolved it over the years; our study sheds light on why Google introduced this practice and analyzes its cu

Short and Long-Term Controls on Active Layer and Permafrost Carbon Turnover Across the Arctic

Decomposition of soil organic matter (SOM) in permafrost terrain and the production of greenhouse gases is a key factor for understanding climate change-carbon feedbacks. Previous studies have shown that SOM decomposition is mostly controlled by soil temperature, soil moisture, and carbon-nitrogen ratio (C:N). However, focus has generally been on site-specific processes and little is known about v

Vascular characteristics in young women-Effect of extensive endurance training or a sedentary lifestyle

Aim: To explore whether high-level endurance training in early age has an influence on the arterial wall properties in young women. Methods: Forty-seven athletes (ATH) and 52 controls (CTR), all 17-25 years of age, were further divided into runners (RUN), whole-body endurance athletes (WBA), sedentary controls (SC) and normally active controls (AC). Two-dimensional ultrasound scanning of the carot

Effect of light-level geolocators on apparent survival of two highly aerial swift species

Light-level geolocators are currently widely used to track the migration of small-sized birds, but their potentially detrimental effects on survival of highly aerial species have been poorly investigated so far. We recorded capture–recapture histories of 283 common swifts Apus apus and 107 pallid swifts Apus pallidus breeding in 14 colonies in Italy, Spain, Sweden and Switzerland that were equippe

RIFM fragrance ingredient safety assessment dihydro-β-terpinyl acetate, CAS Registry Number 26252-11-9

Summary: The use of this material under current conditions is supported by existing information. The material (dihydro-β-terpinyl acetate) was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, as well as environmental safety. Data from the read across analog menthyl acetate (1α,2β,5α) (CAS #

The role of climate, forest fires and human population size in Holocene vegetation dynamics in Fennoscandia

Questions: We investigated the changing role of climate, forest fires and human population size in the broad-scale compositional changes in Holocene vegetation dynamics before and after the onset of farming in Sweden (at 6,000 cal yr BP) and in Finland (at 4,000 cal yr BP). Location: Southern and central Sweden, SW and SE Finland. Methods: Holocene regional plant abundances were reconstructed usin

East Asian Winter Monsoon Variations and Their Links to Arctic Sea Ice During the Last Millennium, Inferred From Sea Surface Temperatures in the Okinawa Trough

The East Asian winter monsoon (EAWM) significantly impacts living conditions in a large part of Asia, and therefore, it is important to understand its major driving mechanisms. Winter sea surface temperature (SSTW) and circulation in the southern Okinawa Trough are today both primarily controlled by the EAWM. Here we present a new SSTW reconstruction for the last millennium based on a diatom recor

Impacts of Anthropogenic Land Use Changes on Nutrient Concentrations in Surface Waterbodies : A Review

Increased population leads to land use (LU) changes from natural to urban and agricultural LU. These disturbances not only decrease the natural treatment potential but they also worsen surface water quality (SWQ). The aim of this review is to assess studies about impacts of anthropogenic LU changes on levels of nutrient concentrations in surface waterbodies, highlighting the important parameters n

Desirable transport futures

This overview article for the special issue on 'Desirable Transport Futures' sets out with a brief introduction of the current development of the global transport system, suggesting that it remains unclear whether transport systems are heading towards desirable change. This desirability is defined as a reduction in the system's negative externalities, including accidents, congestion, pollutants an

A cappella : 25 körledares röster

Hur ser dagens körledare och dirigenter på körverksamhet? Varför är det angeläget att hålla på med kör? Hur arbetar man konstnärligt och pedagogiskt för att utveckla kören och sig själv som körledare? Vad är viktigt att satsa på i utbildningen av nya körledare och körsångare? Hur kan körlivet utvecklas i Sverige och hur ser framtiden ut? I denna bok möter vi tjugofem framstående körledare från oli

Citizenship inclusion and intellectual disability : Biopolitics post-institutionalisation

What happens when a group traditionally defined as lacking the necessary capacities of citizenship is targeted by government programs that have made 'citizenship inclusion' their main goal? Combining theoretical perspectives of political philosophy, social theory, and disability studies, this book untangles the current state of Western intellectual disability politics following the replacement of

Restoring characteristic eigenvalues as reactive powers for simple and complex media in surface integral formulations

The Theory of Characteristic Modes (TCM) has recently been shown to be beneficial in solving a wide variety of complex electromagnetic problems. However, there are still open issues in using TCM to analyze objects which consist of simple or complex media. Either a volume integral equation (VIE) or a surface integral equation (SIE) is required to solve for the characteristic modes of these objects.

Channel capacity analysis of different mobile antenna array topologies in the outdoor urban environment for 5g mm wave system

The 15 and 28 GHz frequency bands have been identified as interesting candidates for future 5G cellular communication systems. In this paper, based on ray-tracing simulations, we investigate the channel capacities at 15 and 28 GHz for a number of different array processing techniques, including beamforming, spatial multiplexing, and two types of hybrid beamforming. This is done for an 8x32 multipl

The human antibacterial cathelicidin, hCAP-18, is bound to lipoproteins in plasma

Cathelicidins are a family of antibacterial and lipopolysaccharide-binding proteins. hCAP-18, the only human cathelicidin, is a major protein of the specific granules of human neutrophils. The plasma level of hCAP-18 is >20-fold higher than that of other specific granule proteins relative to their levels within circulating neutrophils. The aim of this study was to elucidate the background for this

Numerical Benchmark based on characteristic modes of a spherical shell

Characteristic modes of a spherical shell are found analytically and compared with numerical solutions acquired from both in-house and commercial packages. These studies led to a proposal of several independent benchmarks, all with analytically known results. Dependence on mesh size, electrical size and other parameters can easily be incorporated. It is observed that all contemporary implementatio
