The shoot apical meristem (SAM) is responsible for the generation of all the aerial parts of plants. Given its critical role, dynamical changes in SAM activity should play a central role in the adaptation of plant architecture to the environment. Using quantitative microscopy, grafting experiments, and genetic perturbations, we connect the plant environment to the SAM by describing the molecular m
Recently, multiparticle-correlation measurements of relativistic p/d/He3+Au, p+Pb, and even p+p collisions show surprising collective signatures. Here, we present beam-energy-scan measurements of two-, four-, and six-particle angular correlations in d+Au collisions at sNN=200, 62.4, 39, and 19.6 GeV. We also present measurements of two- and four-particle angular correlations in p+Au collisions at
While some mosquitoes are known to have an innate penchant for human hosts, new research details that they can learn, what they can learn and how they can learn.

We show a method for separation of two particle species with different acoustic contrasts originally encapsulated in the same droplet in a continuous two-phase system. This was realized by using bulk acoustic standing waves in a 380 μm wide silicon-glass microfluidic channel. Polystyrene particles (positive acoustic contrast particles) and in-house synthesized polydimethylsiloxane (PDMS) particles
This paper investigates the interaction between economic, demographic and educational variables in post-World War II France. Based on the assumptions of the unified growth theory, we estimate a vector auto-regression for data on fertility, GDP per capita, educational attainment, labor force participation and wages over the period 1962-2008. The methodology employed is based on VAR modeling, using
Peatlands store substantial amounts of carbon and are vulnerable to climate change. We present a modified version of the Organising Carbon and Hydrology In Dynamic Ecosystems (ORCHIDEE) land surface model for simulating the hydrology, surface energy, and CO2 fluxes of peatlands on daily to annual timescales. The model includes a separate soil tile in each 0.5° grid cell, defined from a global peat
Right-wing, xenophobic and racist parties have enjoyed immense successes in Europe in recent decades. In Sweden, the third-largest party in Parliament is the Sweden Democrats (SD), with 13% in the 2014 general election. Sympathy for the SD among foreign-born Swedish citizens, both women and men, is far lower than among Sweden-born men, but an increasing number of Swedish citizens with migrant back
Rope Hadronization is a model extending the Lund string hadronization model to describe environments with many overlapping strings, such as high multiplicity pp collisions or AA collisions. Including effects of Rope Hadronization drastically improves description of strange/non-strange hadron ratios as function of event multiplicity in all systems from e+e- to AA. Implementation of Rope Hadronizati
A CsF-mediated method has been developed for the N-arylation of amino sugars that affords good to excellent yields of arylated products under mild conditions involving the in situ generation of arynes. The reaction conditions tolerate a variety of common carbohydrate protecting groups and also performs exceptionally well on unprotected amino sugar derivatives. The reactions are scalable in moderat
Monosubstituted naphthoxylosides have been shown to function as substrates for, and inhibitors of, the enzyme β4GalT7, a key enzyme in the biosynthetic pathway leading to glycosaminoglycans and proteoglycans. In this article, we explore the synthesis of 16 xyloside analogues, modified at two different positions, as well as their function as inhibitors of and/or substrates for the enzyme. Seemingly
Spectator violence is an issue that affects many football matches in Sweden and other countries. Different models have tried to explain why individuals participate in sports fandom and associated behaviors. However, often these models ignore social and individual factors that may impact if and why individuals participate in spectator violence. Outgroup violence can be motivated by pro-social conce
Philosophers have applied the framework of constitutive grounds to make sense of the disagreement between subjectivism and objectivism. The framework understands the two theories as being involved in a disagreement about the extent to which value is determined by attitudes. Although the framework affords us with some useful observations about how this should be interpreted, the question how value
Advanced glycation end products are formed by non-enzymatic reactions between proteins and carbohydrates, causing irreversible lysine and arginine alterations that severely affect protein structure and function. The resulting modifications induce inflammation by binding to scavenger receptors. An increase in advanced glycation end products is observed in a number of diseases e.g. atherosclerosis a
This article analyzes the effect of exporting activity on the innovative performances of firms in France, Germany, Italy, Spain, and UK. It argues that the positive effect of exporting on innovation usually found in the literature varies according to the specific destinations of exports, and it identifies two dimensions along which export destinations might differ: the level of foreign technologic
One common goal of sample analysis is to provide structural, compositional, or functional data in order to improve production parameters. One instrument specialized in such structural and compositional analysis with a high spatial resolution is the transmission electron microscope (TEM). The high-end microscopes have the capability of sub-Ångström resolution and compositional quantification and di
This thesis introduces two new incommensurate alloys. AuIn shows variable amounts of modulation, depending on the measurement temperature. At 400°C the diffraction pattern shows diffuse scattering and a thallium iodide type Cmcm space group. The diffuse scattering condenses into first order satellites on cooling to 300°C and the space group transforms to the incommensurate C-1(α, β, γ)0. I.e. the
The iron carbene complex [FeII(btz)3](PF6)2 (where btz = 3,3′-dimethyl-1,1′-bis(p-Tolyl)-4,4′-bis(1,2,3-Triazol-5-ylidene)) has been synthesized, isolated, and characterized as a low-spin ferrous complex. It exhibits strong metal-To-ligand charge transfer (MLCT) absorption bands throughout the visible spectrum, and excitation of these bands gives rise to a 3MLCT state with a 528 ps excited-state l
Objective To subgroup chronic pain patients using psychometric data and regress the variables most responsible for subgroup discrimination. Design Cross-sectional, registry-based study. Setting and subjects Chronic pain patients assessed at a multidisciplinary pain centre between 2008 and 2015. Methods Data from the Swedish quality registry for pain rehabilitation (SQRP) were retrieved and analyse
