H-alpha emission lines in high-redshift quasars
(1989)Infrared spectra have been obtained of the H-alpha lines in 18 medium- to high-redshift QSOs and optical spectra taken nearly simultaneously to measure the strong UV line. It is found that the H-alpha line is redshifted ... -
H-NS silences gfp, the Green Fluorescent Protein gene: gfpTCD is a genetically remastered gfp gene with reduced susceptibility to H-NS-mediated transcription silencing and with enhanced translation
(2010)The bacterial nucleoid-associated protein H-NS, which preferentially targets and silences A+T-rich genes, binds the ubiquitous reporter gene gfp and dramatically reduces local transcription. We have redesigned gfp to reduce ... -
H2B ubiquitylation is part of chromatin architecture that marks exon-intron structure in budding yeast
(2011)Background The packaging of DNA into chromatin regulates transcription from initiation through 3' end processing. One aspect of transcription in which chromatin plays a poorly understood role is the co-transcriptional ... -
Habitability in the Treaty Ports: Shanghai and Tianjin

Habitat Fragmentation Increases Overall Richness, but Not of Habitat-Dependent Species
(2020)Debate rages as to whether habitat fragmentation leads to the decline of biodiversity once habitat loss is accounted for. Previous studies have defined fragmentation variously, but research needs to address “fragmentation ... -
Habits in Consumption, Transactions Learning and Economic Growth
(2005)This paper presents a model of endogenous growth in the presence of habit formation in consumption. We argue that in addition to the traditional disutility effects of habitual consumption, the past history of consumption ... -
Habitual physical activity and cardiometabolic risk factors in adults with cerebral palsy
(2014)Adults with cerebral palsy (CP) are known to participate in reduced levels of total physical activity. There is no information available however, regarding levels of moderate-to-vigorous physical activity (MVPA) in this ... -
Hadron spectroscopy from lattice quantum chromodynamics
(2016)Lattice calculations of hadron spectroscopy are discussed. A brief introduction to numerical simulations of QCD, with a focus on spectroscopy is given. Results for spectroscopy of low-lying, excited and exotic states ... -
Haemodynamic Parameters Underlying the Relationship Between Sarcopenia and Blood Pressure Recovery on Standing
(2023)Background: Sarcopenia, delayed blood pressure (BP) recovery following standing, and orthostatic hypotension (OH) pose significant clinical challenges associated with ageing. While prior studies have established a link ... -
Haldane limits via Lagrangian embeddings
(Elsevier, 2012)In the present paper we revisit the so-called Haldane limit, i.e. a particular continuum limit, which leads from a spin chain to a sigma model. We use the coherent state formulation of the path integral to reduce the problem ... -
The Hall Technique 10 years on: Questions and answers.
(2017)It is ten years since the first paper on the Hall Technique was published in the British Dental Journal and almost 20 years since the technique first came to notice. Dr Norna Hall a (now retired) general dental practitioner ... -
Halloysite- and Montmorillonite-Loaded Scaffolds as Enhancers of Chronic Wound Healing
(2020)The increase in life expectancy and the increasing prevalence of diabetic disease and venous insufficiency lead to the increase of chronic wounds. The prevalence of ulcers ranges from 1% in the adult population to 3–5% in ... -
Hamiltonian lattice gauge models and the Heisenberg double
(World Scientific, 1995)Hamiltonian lattice gauge models based on the assignment of the Heisenberg double of a Lie group to each link of the lattice are constructed in arbitrary spacetime dimensions. It is shown that the corresponding generalization ... -
Hand-held dynamometry: tester strength is paramount, even in frail populations.
(2011)To determine test-retest and inter-rater reliability of hand-held dynamometry when used to measure knee--extensor strength in patients with advanced cancer. SUBJECTS: Adults with metastatic or locally advanced cancer ... -
Hands in Motion: Learning to Fingerspell in Irish Sign Language (ISL)
(2020)Irish Sign Language uses a one-handed alphabet in which each fingerspelled letter has a unique combination of handshape, orientation, and, in a few cases, path movement. Each letter is used to represent ... -
Hands-free sample preparation platform for nucleic acid analysis.
(2009)A Lab-On-Chip system with an instrument is presented which is capable of performing total sample preparation and automated extraction of nucleic acid from human cell samples fixed in a methanol based solution. The target ... -
Haploinsufficiency for AAGAB causes clinically heterogeneous forms of punctate palmoplantar keratoderma.
(2012)Palmoplantar keratodermas (PPKs) are a group of disorders that are diagnostically and therapeutically problematic in dermatogenetics. Punctate PPKs are characterized by circumscribed hyperkeratotic lesions on the palms and ... -
Hard borders and soft agreements: Evaluating governance within the Global Compact for Migration
(Routledge, 2023)Welcomed as a milestone in the governance of transnational migration, the adoption of the Global Compact for Safe, Orderly, and Regular Migration marked a significant step forward in international cooperation on migration ...
