Transport and structural study of pressure-induced magnetic states in Nd0.55Sr0.45MnO3 and Nd0.5Sr0.5MnO3

Pressure effects on the electron transport and structure of Nd1-xSrxMnO3 (x = 0.45, 0.5) were investigated in the range from ambient to ~6 GPa. In Nd0.55Sr0.45MnO3, the low-temperature ferromagnetic metallic state is suppressed and a low temperature insulating state is induced by pressure. In Nd0.5Sr0.5MnO3, the CE-type antiferromagnetic charge-ordering state is suppressed by pressure. Under pressure, both samples have a similar electron transport behavior although their ambient ground states are much different. It is surmised that pressure induces an A-type antiferromagnetic state at low temperature in both compounds

NS Ghost Slivers

Neveu-Schwarz ghost slivers in pictures zero and minus one are constructed. In particular, using algebraic methods $\beta$, $\gamma$ ghost sliver in the -1 picture is obtained. The algebraic method consists in solving a projector equation in an algebra, where the multiplication is defined by a pure 3-string vertex without any insertions at the string midpoint. We show that this projector is a sliver in a twisted version of $\beta$, $\gamma$ conformal theory. We also show that the product of the twisted $b$, $c$ and $\beta$, $\gamma$ ghost slivers solves an equation that appears after a special rescaling of super VSFT.Comment: 27 pages, LATE

Risk profiles and one-year outcomes of patients with newly diagnosed atrial fibrillation in India: Insights from the GARFIELD-AF Registry.

BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.

Supplementary Material for: PHACE(S) SYNDROME WITH OCULAR INVOLVEMENTS AND NO PERIOCULAR HAEMANGIOMA

PHACE(S) syndrome is a neurocutaneous disorder with a hallmark finding of an infantile facial hemangioma (IFH) > 5cm. Eye examination of patients with PHACE(S) syndrome with no IFH at periorbital region is reported to be of low yield. We report a unique case of the syndrome with ocular manifestations without periorbital IFH or systemic findings. A 3-week-old female infant with right periauricular IFH > 5cm, extending to the neck and cheek and with lower lip IFH. Examination revealed pseudoptosis due to microphthalmia with esotropia and hypertropia. Both corneas were clear with diameters of 5mm and 10mm, right eye (RE) and left eye (LE), respectively. There was a posterior polar cataract with a poor view of the fundus RE. Ocular B-scan and magnetic resonance imaging (MRI) findings were suggestive of a dysmorphic globe, vitreous hemorrhage, spherophakia and persistent fetal vasculature RE and normal findings LE. Clinical evaluation, MRI and MR angiography revealed no other systemic abnormalities. Subsequent follow-up visits revealed progressive clouding of the cornea with neovascularization and the development of phthisis bulbi RE at which point an ocular prosthesis was placed. The IFH was managed with dye laser and with oral propranolol. At one year, the patient has remained stable with no development of new local or systemic anomalies, regression of the periauricular and lip IFH and normal development of the orbital structure RE with an ocular prosthesis in situ. Ocular involvement in patients with PHACE(S) syndrome may be present without periorbital IFH. Regardless of the location of the IFH and the presence or absence of a periocular component, it is recommended that they receive a full initial ophthalmological assessment
