A borane laser

© 2015 Macmillan Publishers Limited. Emission from electronically excited species forms the basis for an important class of light sources-lasers. So far, commercially available solution-processed blue-emitting laser materials are based on organic compounds or semiconductor nanocrystals that have significant limitations: either low solubility, low chemical-and/or photo-stability and/or uncompetitive prices. Here we report a novel and competitive alternative to these existing laser materials that is based on boron hydrides, inorganic cluster compounds with a rich and diverse chemistry. We demonstrate that solutions of the borane anti-B 18 H 22 show, under pulsed excitation, blue laser emission at 406 nm with an efficiency (ratio of output/input energies) of 9.5%, and a photostability superior to many of the commercially available state-of-the-art blue laser dyes. This demonstration opens the doors for the development of a whole new class of laser materials based on a previously untapped resource for laser technology-the boranes.Peer Reviewe

Based on the agency and socioemotional wealth (SEW) perspectives, this paper examines the formalization and effectiveness of three basic HR practices – selection, training, and compensation – in different contexts of family and non-family firms. Using a sample of 500 Spanish companies, the results show that a higher degree of HR formalization has a positive influence on firm performance, confirming the negative moderating influence of family involvement on the relationship between the formalization of training practices and the firm performance. In addition, the findings indicate that the mediating role of selection practices in the relationship between training and firm performance is smaller in family than in non-family firm

Prácticas de recursos humanos en la empresa familiar: profesionalización y efecto sobre el desempeño

La influencia de la familia en las estructuras de gestión del capital humano de la empresa crea un marco único y diferente, con importantes implicaciones en términos de eficiencia. En este trabajo se examina la orientación de las principales prácticas de recursos humanos –selección, formación y retribución- y sus efectos sobre el desempeño organizativo en función de la presencia de la familia en la propiedad y dirección del negocio. Utilizando una muestra de 500 empresas españolas, los resultados indican que en las empresas de dirección familiar se aplican unas prácticas de recursos humanos menos formalizadas y profesionalizadas que en las empresas familiares de dirección externa. Asimismo, se comprueba una contribución de las prácticas de recursos humanos a través de la selección que se encuentra moderada negativamente por el carácter familiar.&nbsp

Parallelization of the PC Algorithm

This paper describes a parallel version of the PC algorithm for learning the structure of a Bayesian network from data. The PC algorithm is a constraint-based algorithm consisting of fi ve steps where the first step is to perform a set of (conditional) independence tests while the remaining four steps relate to identifying the structure of the Bayesian network using the results of the (conditional) independence tests. In this paper, we describe a new approach to parallelization of the (conditional) independence testing as experiments illustrate that this is by far the most time consuming step. The proposed parallel PC algorithm is evaluated on data sets generated at random from five different real- world Bayesian networks. The results demonstrate that signi cant time performance improvements are possible using the proposed algorithm

Circularly polarized laser emission induced in isotropic and achiral dye systems

The production of efficient, tunable, and switchable circularly polarized laser emission would have far reaching implications in optical communications or biophotonics. In this work, it is demonstrated the direct generation of circularly polarized (CP) laser emission in achiral and isotropic dye laser systems without the use of extracavity polarizing elements, and without resorting to chiral dyes, chiral liquid crystal matrices, or interferometric methods. The origin of this ellipticity arises from the dynamic birefringence induced by the strong and polarized laser pumping and the subsequent orientation anisotropy of the excited molecular dipoles. A complete polarimetric characterization of the polarization state of conventional dye laser oscillators as a function of different experimental parameters is performed and it is shown that the generated light always possesses a certain level of circularity that changes in a distinctive way with pump energy and polarization. These results demonstrate that it is possible to generate and modulate CP laser light from efficient and photostable conventional laser dyes.Peer Reviewe

A thylakoid membrane-bound and redox-active rubredoxin (RBD1) functions in de novo assembly and repair of photosystem II.

Photosystem II (PSII) undergoes frequent photooxidative damage that, if not repaired, impairs photosynthetic activity and growth. How photosynthetic organisms protect vulnerable PSII intermediate complexes during de novo assembly and repair remains poorly understood. Here, we report the genetic and biochemical characterization of chloroplast-located rubredoxin 1 (RBD1), a PSII assembly factor containing a redox-active rubredoxin domain and a single C-terminal transmembrane α-helix (TMH) domain. RBD1 is an integral thylakoid membrane protein that is enriched in stroma lamellae fractions with the rubredoxin domain exposed on the stromal side. RBD1 also interacts with PSII intermediate complexes containing cytochrome b 559 Complementation of the Chlamydomonas reinhardtii (hereafter Chlamydomonas) RBD1-deficient 2pac mutant with constructs encoding RBD1 protein truncations and site-directed mutations demonstrated that the TMH domain is essential for de novo PSII assembly, whereas the rubredoxin domain is involved in PSII repair. The rubredoxin domain exhibits a redox midpoint potential of +114 mV and is proficient in 1-electron transfers to a surrogate cytochrome c in vitro. Reduction of oxidized RBD1 is NADPH dependent and can be mediated by ferredoxin-NADP+ reductase (FNR) in vitro. We propose that RBD1 participates, together with the cytochrome b 559, in the protection of PSII intermediate complexes from photooxidative damage during de novo assembly and repair. This role of RBD1 is consistent with its evolutionary conservation among photosynthetic organisms and the fact that it is essential in photosynthetic eukaryotes

APPRIS: selecting functionally important isoforms.

APPRIS (https://appris.bioinfo.cnio.es) is a well-established database housing annotations for protein isoforms for a range of species. APPRIS selects principal isoforms based on protein structure and function features and on cross-species conservation. Most coding genes produce a single main protein isoform and the principal isoforms chosen by the APPRIS database best represent this main cellular isoform. Human genetic data, experimental protein evidence and the distribution of clinical variants all support the relevance of APPRIS principal isoforms. APPRIS annotations and principal isoforms have now been expanded to 10 model organisms. In this paper we highlight the most recent updates to the database. APPRIS annotations have been generated for two new species, cow and chicken, the protein structural information has been augmented with reliable models from the EMBL-EBI AlphaFold database, and we have substantially expanded the confirmatory proteomics evidence available for the human genome. The most significant change in APPRIS has been the implementation of TRIFID functional isoform scores. TRIFID functional scores are assigned to all splice isoforms, and APPRIS uses the TRIFID functional scores and proteomics evidence to determine principal isoforms when core methods cannot.National Human Genome Research Institute of the National Institutes of Health [2 U41 HG007234]; Spanish Ministry of Science, Innovation and Universities [PGC2018-097019-B-I00]; Carlos III Institute of Health-Fondo de Investigacion Sanitaria [PRB3 ´ (IPT17/0019––ISCIII-SGEFI/ERDF, ProteoRed]; ‘la Caixa’ Banking Foundation [HR17-00247].

Quantitative comparison between different methods for the determination of the amplified spontaneous emission threshold in dye-polymer blends and perovskite thin films

Amplified Spontaneous Emission (ASE) properties and ASE threshold are usually investigated for the characterization of a candidate active material for laser applications. However, the comparison among different materials is often hampered by the use in literature of several different methods to estimate the ASE threshold. In this work we quantitatively compare the ASE threshold values obtained by using the most employed methods in dye-doped polymer and lead halide perovskite thin films, highlighting the dependence of the value obtained on the applied method
