Micro-Raman spectroscopy for the detection of stacking fault density in InAs and GaAs nanowires

We investigate the relation between crystal stacking faults in individual wurtzite InAs and GaAs nanowires and the intensity of the forbidden longitudinal optical (LO) phonon mode in the Raman spectra. Micro-Raman spectroscopy and transmission electron microscopy are combined on the same individual nanowires to evaluate the LO mode intensity as a function of the stacking fault density. A clear inc

Floquet engineering of long-range p -wave superconductivity : Beyond the high-frequency limit

It has been shown that long-range p-wave superconductivity in a Kitaev chain can be engineered via an ac field with a high frequency [M. Benito, Phys. Rev. B 90, 205127 (2014)PRBMDO1098-012110.1103/PhysRevB.90.205127]. For its experimental realization, however, theoretical understanding of Floquet engineering with a broader range of driving frequencies becomes important. In this paper, focusing on

The large enriched germanium experiment for neutrinoless double beta decay (LEGEND)

The observation of neutrinoless double-beta decay (0νββ) would show that lepton number is violated, reveal that neu-trinos are Majorana particles, and provide information on neutrino mass. A discovery-capable experiment covering the inverted ordering region, with effective Majorana neutrino masses of 15 - 50 meV, will require a tonne-scale experiment with excellent energy resolution and extremely

Yeast-bacteria competition induced new metabolic traits through large-scale genomic rearrangements in Lachancea kluyveri

Large-scale chromosomal rearrangements are an important source of evolutionary novelty that may have reshaped the genomes of existing yeast species. They dramatically alter genome organization and gene expression fueling a phenotypic leap in response to environmental constraints. Although the emergence of such signatures of genetic diversity is thought to be associated with human exploitation of y

Radiolar eyes of serpulid worms (Annelida, serpulidae) : Structures, function, and phototransduction

Fan worms, represented by sabellid and serpulid polychaetes, have an astonishing array of unusual eyes and photoreceptors located on their eponymous feeding appendages. Here we organize the previous descriptions of these eyes in serpulids and report new anatomical, molecular, and physiological data regarding their structure, function, and evolution and the likely identity of their phototransductio

Large-scale evidence for the effect of the COLIA1 Sp1 polymorphism on osteoporosis outcomes : the GENOMOS study

BACKGROUND: Osteoporosis and fracture risk are considered to be under genetic control. Extensive work is being performed to identify the exact genetic variants that determine this risk. Previous work has suggested that a G/T polymorphism affecting an Sp1 binding site in the COLIA1 gene is a genetic marker for low bone mineral density (BMD) and osteoporotic fracture, but there have been no very-lar

Association of oestrogen receptor alpha gene polymorphisms with postmenopausal bone loss, bone mass, and quantitative ultrasound properties of bone

BACKGROUND: The gene encoding oestrogen receptor alpha (ESR1) appears to regulate bone mineral density (BMD) and other determinants of osteoporotic fracture risk.OBJECTIVE: To investigate the relation between common polymorphisms and haplotypes of the ESR1 gene and osteoporosis related phenotypes in a population based cohort of 3054 Scottish women.RESULTS: There was a significant association betwe

Differential genetic effects of ESR1 gene polymorphisms on osteoporosis outcomes

CONTEXT: Both bone mineral density (BMD) and fracture risk have a strong genetic component. Estrogen receptor alpha (ESR1) is a candidate gene for osteoporosis, but previous studies of ESR1 polymorphisms in this field were hampered by small sample size, lack of standardization, and inconclusive results.OBJECTIVE: To generate large-scale evidence on whether 3 common ESR1 polymorphisms (intron 1 pol

Linkage disequilibrium between polymorphisms in the human TNFRSF1B gene and their association with bone mass in perimenopausal women

Osteoporosis is a multifactorial disease with a strong genetic component characterized by reduced bone density and increased fracture risk. A candidate locus for regulation of hip bone mineral density (BMD) has been identified on chromosome 1p36 by linkage analysis. One of the positional and functional candidate genes located within this region is the tumour necrosis factor receptor superfamily me

Genetic and environmental determinants of peak bone mass in young men and women

Peak bone mass is an important risk factor for the development of osteoporosis in later life. Previous work has suggested that genetic, intrauterine, and environmental factors all contribute to the regulation of bone mass, but the ways in which they interact with each other to do so remain poorly understood. In this study, we investigated the relationship between peak bone mass and polymorphisms o

The contribution of feminist perspectives to climate governance

Feminist analysis focuses on gender relations, thereby it goes beyond a mere focus on women and women’s role in climate governance. While the representation of women in politics and governance is of relevance to such studies, feminist theory makes it possible to also seriously discuss and question the relation between women’s and men’s interests and values in the gender order, and problematize the

Association between COLIA1 Sp1 alleles and femoral neck geometry

Genetic factors play an important role in the pathogenesis of osteoporosis by affecting bone mineral density and other predictors of osteoporotic fracture risk such as ultrasound properties of bone and skeletal geometry. We previously identified a polymorphism of a Sp1 binding site in the Collagen Type 1 Alpha 1 gene (COLIA1) that has been associated with reduced BMD and an increased risk of osteo

Estrogen receptor alpha gene polymorphisms and bone mineral density : haplotype analysis in women from the United Kingdom

Genetic factors are important in the pathogenesis of osteoporosis and the estrogen receptor has been suggested as a possible candidate gene for regulation of bone mineral density (BMD). We investigated the relationship between PvuII, XbaI, and dinucleotide (TA)n repeat polymorphisms of the estrogen receptor alpha (ER-alpha) gene and BMD in a study of women from northeast Scotland in the United Kin

Prediction of osteoporotic fractures by bone densitometry and COLIA1 genotyping : a prospective, population-based study in men and women

Osteoporosis is a common disease with a strong genetic component, characterized by reduced bone mineral density and increased fracture risk. Although the genetic basis of osteoporosis is incompletely understood, previous studies have identified a polymorphism affecting an Sp1 binding site in the COLIA1 gene that predicts bone mineral density and osteoporotic fractures in several populations. Here

COL1A1 Sp1 polymorphism predicts perimenopausal and early postmenopausal spinal bone loss

Genetic factors play an important role in the pathogenesis of osteoporosis but the genes that determine susceptibility to poor bone health are defined incompletely. Previous work has shown that a polymorphism that affects an Spl binding site in the COLIA1 gene is associated with reduced bone mineral density (BMD) and an increased risk of osteoporotic fracture in several populations. Data from cros
