Summertime observations of ultrafine particles and cloud condensation nuclei from the boundary layer to the free troposphere in the Arctic
2016
Abstract. The Arctic is extremely sensitive to climate change. Shrinking sea ice extent increases the area covered by open ocean during Arctic summer, which impacts the surface albedo and aerosol and cloud properties among many things. In this context extensive aerosol measurements (aerosol composition, particle number and size, cloud condensation nuclei, and trace gases) were made during 11 flights of the NETCARE July, 2014 airborne campaign conducted from Resolute Bay, Nunavut (74N, 94W). Flights routinely included vertical profiles from about 60 to 3000 m a.g.l. as well as several low-level horizontal transects over open ocean, fast ice, melt ponds, and polynyas. Here we discuss the vert…
Reproducibility and concordance of 4 clinically developed programmed death-ligand 1 (PD-L1) immunohistochemistry (IHC) assays in triple negative brea…
2019
Abstract Background Atezolizumab (an anti–PD-L1 antibody) has shown clinical activity alone or in combination with nab-paclitaxel in patients (pts) with first-line metastatic TNBC who have PD-L1 expression on their tumour-infiltrating immune cells (IC). We analysed the performance of 4 PD-L1 IHC assays for PD-L1 IC expression in TNBC. Methods Thirty archival TNBC tissue specimens were selected from a set of 107 based on PD-L1 IC expression per VENTANA SP142 ( 5%: 8 cases), to represent the distribution of PD-L1 IC–positivity in the pivotal atezolizumab studies (Emens et al., SABCS 2018; JAMA Oncol 2019). Serial histologic sections were stained with VENTANA SP142 and SP263, and DAKO 22C3 and…
A detailed identification study on high-temperature degradation products of oleic and linoleic acid methyl esters by GC–MS and GC–FTIR
2012
GC-MS and GC-FTIR were complementarily applied to identify oxidation compounds formed under frying conditions in methyl oleate and linoleate heated at 180ºC. The study was focused on the compounds that originated through hydroperoxide scission that remain attached to the glyceridic backbone in fats and oils and form part of non-volatile molecules. Twenty one short-chain esterified compounds, consisting of 8 aldehydes, 3 methyl ketones, 4 primary alcohols, 5 alkanes and 1 furan, were identified. In addition, twenty non-esterified volatile compounds, consisting of alcohols, aldehydes and acids, were also identified as major non-esterified components. Furanoid compounds of 18 carbon atoms form…
The moral work of becoming a professional
2021
Abstract In contemporary working life, art-based initiatives are increasingly used in organizational training and development. For artists, this has created new employment opportunities as creative entrepreneurs who provide specialist services for workplaces. In this article, we study the dynamics of such encounters through the narrated accounts of training professionals. Our data come from a professional mentoring program where the working pairs of artists and consultants shared stories about their customer projects. By using conversation analysis as a method, we analyze the way stories are interactionally accomplished in peer group sessions of the program. In particular, we analyze how pa…
Neither a toda virolla nor tumbados a la bartola. A corpus analysis of phraseologically bound spanish words
2021
[EN] This article presents results on the Spanish phraseologically bound words (PLF), also known as cranberry words, based on a corpus analysis. If up to now the different Spanish PLF had been collected introspectively, this article presents a list of the Spanish PLF indicating the phraseological fixation index (IFF) of each one of them in the phraseological unit (UF) that contains them and ordered by the weighted phraseological fixation index (IFFP). To do this, it has been necessary to obtain from the corpus the total number of occurrences of the PLF (NPLF) and to analyse the fixation of these elements both inside the UF or the UFS that contain them (FFPLF) and outside the UF, in their fr…
The Role of Work-Nonwork Boundary Management in Work Stress Recovery
2016
The aim of the present study conducted among 1,106 Finnish employees was to identify boundary management profiles based on cross-role interruption behaviors from work to nonwork and from nonwork to work. Adopting a person-oriented approach through latent profile analysis, 5 profiles were identified: Work Guardians (21% of the employees), Nonwork Guardians (14%), Integrators (25%), Separators (18%), and an Intermediate Group (22%). We then examined differences between these profiles with respect to recovery experiences ( psychological detachment from work, relaxation, mastery experiences, and control during off-job time) and recovery outcomes (vigor and exhaustion). Work Guardians had the po…
Asymmetry matters: Dynamic half-way points in bidirectional labeling for solving shortest path problems with resource constraints faster
2017
Abstract With their paper “Symmetry helps: Bounded bi-directional dynamic programming for the elementary shortest path problem with resource constraints” [Discrete Optimization 3, 2006, pp. 255–273] Righini and Salani introduced bounded bidirectional dynamic programming (DP) as an acceleration technique for solving variants of the shortest path problem with resource constraints (SPPRC). SPPRCs must be solved iteratively when vehicle routing and scheduling problems are tackled via Lagrangian relaxation or column-generation techniques. Righini and Salani and several subsequent works have shown that bounded bidirectional DP algorithms are often superior to their monodirectional counterparts, s…
Packing colorings of subcubic outerplanar graphs
2018
Given a graph $G$ and a nondecreasing sequence $S=(s_1,\ldots,s_k)$ of positive integers, the mapping $c:V(G)\longrightarrow \{1,\ldots,k\}$ is called an $S$-packing coloring of $G$ if for any two distinct vertices $x$ and $y$ in $c^{-1}(i)$, the distance between $x$ and $y$ is greater than $s_i$. The smallest integer $k$ such that there exists a $(1,2,\ldots,k)$-packing coloring of a graph $G$ is called the packing chromatic number of $G$, denoted $\chi_{\rho}(G)$. The question of boundedness of the packing chromatic number in the class of subcubic (planar) graphs was investigated in several earlier papers; recently it was established that the invariant is unbounded in the class of all sub…
A posteriori error majorants of the modeling errors for elliptic homogenization problems
2013
In this paper, we derive new two-sided a posteriori estimates of the modeling errors for linear elliptic boundary value problems with periodic coefficients solved by homogenization. Our approach is based on the concept of functional a posteriori error estimation. The estimates are obtained for the energy norm and use solely the global flux of the non-oscillatory solution of the homogenized model and solution of a boundary value problem on the cell of periodicity.
