Testing theories of Gravity and Supergravity with inflation and observations of the cosmic microwave background

2016

Many extensions of Einstein's theory of gravity have been studied and proposed with various motivations like the quest for a quantum theory of gravity to extensions of anomalies in observations at the solar system, galactic and cosmological scales. These extensions include adding higher powers of Ricci curvature $R$, coupling the Ricci curvature with scalar fields and generalized functions of $R$. In addition when viewed from the perspective of Supergravity (SUGRA) many of these theories may originate from the same SUGRA theory interpreted in different frames. SUGRA therefore serves as a good framework for organizing and generalizing theories of gravity beyond General Relativity. All these …

ChemInform Abstract: Molybdenum Pentachloride Mediated Synthesis of Spirocyclic Compounds by Intramolecular Oxidative Coupling.

2016

Oxidative treatment of 4-methoxy substituted 2-aryl cinnamates leads to an dealkylative C—C coupling and gives access to spirocyclic compounds.

Coupling evanescently low loss Silicon-on-insulator ridge waveguides including high Q nanocavities for light control

2011

Summary form only given. In this work, we propose an innovative way to achieve an air-slotted nanocavities by coupling evanescently low loss Silicon-on-insulator (SOI) ridge waveguides(WGs) including high Q nanocavities exhibiting an ultrasmall modal volume V. We first show that coupling two WGs allows us to achieve a field confinement within the air slot as low as lambda/30 while preserving a high group index of the guided modes. Then we demonstrate that merging such coupled WGs with state-of-the-art high-Q/small V nanocavities is a robust way to achieve a single compact (1 µm × 3 µm) air-slotted resonator on substrate. Finally, we extend the concept to multiple air-slotted resonator syste…

Lithotectonic elements and geological events in the Hengshan–Wutai–Fuping belt: a synthesis and implications for the evolution of the Trans-North Chi…

2007

The Hengshan–Wutai–Fuping belt is located in the middle segment of the Trans-North China Orogen, a Palaeoproterozoic continental collisional belt along which the Eastern and Western blocks amalgamated to form the North China Craton. The belt consists of the medium- to high-grade Hengshan and Fuping gneiss complexes and the intervening low- to medium-grade Wutai granite–greenstone terrane, and most igneous rocks in the belt are calc-alkaline and have affinities to magmatic arcs. Previous tectonic models assumed that the Hengshan and Fuping gneiss assemblages were an older basement to the Wutai supracrustal rocks, but recent studies indicate that the three complexes constitute a single, long-…

To investigate cum “granuloma” salis: Chronic granulomatous disease vs Crohn's disease

2020

Chronic granulomatous disease (CGD) is a rare inherited disorder of phagocyte oxidative metabolism that, in addition to infectious complications, is characterized by abnormal inflammatory response leading to the formation of granulomas in multiple tissues both in the presence and absence of microorganisms. Inflammation often involves the gastrointestinal tract and the clinical, laboratory, and histological characteristics are hardly distinguishable from Crohn's disease (CD). CGD is indeed a rare but important differential diagnosis of chronic inflammatory bowel disease (IBD) especially when occurring in early life and its early detection is crucial to improve the prognosis. The paper report…

OP20 Risk and predictors of surgery in a newly diagnosed cohort of IBD patients in the biologic era: Results from the EpidemIBD study

2021

Abstract Background The management of inflammatory bowel disease (IBD) has substantially changed in the last decades, both in relation to medical and surgical treatments. Aims Principal: To know the rate of surgery in a newly diagnosed IBD cohort within the first year after diagnosis. Secondary: To describe the type of surgeries and indications in this cohort, and to identify predictive factors for surgery (focused on intestinal resection) in these patients. Methods Prospective, population-based nationwide registry. Adult patients diagnosed with IBD -Crohn’s disease (CD) and ulcerative colitis (UC)- during 2017 in Spain were included and were followed-up for 1 year. Kaplan-Meier curves were…

Large retroperitoneal abscess extended to the inferior right limb secondary to a perforated ileal Crohn’s disease: the importance of the multidiscipl…

2016

The typical complications of Crohn's disease concerns small and large bowel. The full thickness inflammation of the intestinal wall develops in strictures, fistulas and abdominal abscesses. Nowadays the most accepted therapeutic for intra-abdominal abscess option is antibiotic therapy and, in case of need, percutaneous drainage of the abscess. If the abscess passes through the pelvic foramen the abscess can involve the inferior limbs. We report a case a perforation of terminal ileum in Crohn's disease complicated by a large abscess of the right iliac fossa reaching the spaces between the anterior lateral muscles of the right thigh as far as the anterior lateral pre-tibial region. We discuss…
