Highly efficient estimation of entanglement measures for large experimentally created graph states via simple measurements

Quantifying experimentally created entanglement could in principle be accomplished by measuring the entire density matrix and calculating an entanglement measure of choice thereafter. Due to the tensor structure of the Hilbert space, this approach becomes unfeasible even for medium-sized systems. Here we present methods for quantifying the entanglement of arbitrarily large two-colorable graph states from simple measurements. The presented methods provide non-trivial bounds on the entanglement for any state as long as there is sufficient fidelity with such a graph state. The measurement data considered here is merely given by stabilizer measurements, thus leading to an exponential reduction in the number of measurements required. We provide analytical results for the robustness of entanglement and the relative entropy of entanglement

Abnormal uterine bleeding in a woman with caesarean scar defect (isthmocele): a case report

The caesarean scar defect generally is described as a triangular or circular sonographically anechoic area in the myometrium of the anterior lower uterine segment or cervix at the site of a previous caesarean section. Caesarean section is one of the most commonly performed surgeries and the trend is increasing in the recent years. One long-term complication of caesarean delivery which is not often discussed is the presence of a defect within the uterine scar that is directly associated with a type of abnormal uterine bleeding (AUB) referred to as postmenstrual bleeding. In addition to AUB, presented as pelvic pain, dyspareunia, dysmenorrhea, unexplained infertility. Caesarean scar defect is one such cause of AUB which is overlooked as the history of caesarean section will be many years ago. One such case of woman presenting with abnormal uterine bleeding and pain in abdomen with caesarean defect who was managed in our tertiary care centre reported here

Groundwater management options in North district of Delhi, India: A groundwater surplus region in over-exploited aquifers

AbstractStudy regionNorth district of Delhi, India.Study focusThe North district of Delhi has mostly shallow water levels and is a groundwater surplus region in contrast to the over-exploited aquifers of the region. The surface runoff and flood waters during monsoon season in the district either causes water logging in lower elevation areas or they join drains and rivers as rejected recharge. This study aims to understand groundwater dynamics of the region in perspective of the aquifer architecture and proposes groundwater management options to meet local water requirements.New hydrological insights in the regionThree distinct hydrogeological domains are identified with subtle differences in groundwater occurrence. Insights are obtained in stream–aquifer interaction and baseflow to the Yamuna River is quantified. The salinity enrichment in groundwater has been attributed to water logging in clay rich formations under semi arid condition. The viability of limited dewatering of shallow aquifers and its replenishment by enhanced recharge from surface runoff and flood waters during the monsoon period have been established

Assessment of prescribing trends for rational use of drugs

Background: Nowadays irrational use of drugs is a major problem inspite of extensive programs being carried out on rational use of medicines. Therefore, in present study we evaluated OPD prescriptions for rationality and their adherence to prescription format.Methods: A prospective, observational study was carried out in 511 outdoor patients for a period of three months. Quality of prescription writing was assessed for completeness of information and legibility. Rationality was analyzed using WHO core prescribing indicators.Results: Basic information of patient and name of department were written in all the prescriptions. Diagnosis was mentioned in 76.33% cases. Dosage forms, dose, frequency and duration of treatment were mentioned in 97.26%, 73%, 80.04% and 80.23% of prescriptions respectively. About 73.78% prescriptions were legible. Doctor’s name, signature and registration number were present in 80.82%, 82.97% and 15.66%. Total number of drugs in 511 cases was 1074. Average number of drugs/ prescriptions was 2.1±0.8. Drugs were prescribed by generic name in 25.14% cases; drugs from EDL were 57.36%. Antimicrobial agents, injectable drugs and FDCs were prescribed in 25.83%, 12.13% and 39.14% cases. The most commonly prescribed drugs were analgesics, GIT and cardiovascular drugs.Conclusions:This study shows possible areas of improvement in prescription practice that is generic prescribing, use of essential medicines, restraint in use of irrational fixed dose combinations and better quality of prescribing in terms of inclusiveness of information, legibility and doctor’s details.

A role of biomarkers in systemic lupus erythematous: a comprehensive review

Systemic lupus erythematous (SLE) is an auto immune disease that can involve almost all body organs. Lupus erythematous may be classified in to several subtypes according to clinical features including systemic and cutaneous lupus erythematous, drug induced lupus and neonatal lupus. SLE progression includes in the immune system. Pathological manifestation of SLE are due to antibody formation and deposition of immune complexes in different organs of the body. Due to formation or disposition of immune complex in different body tissues and vessels, which may lead to complement activation and more organ damage. Other factors include genetic factors, hormonal abnormalities and environmental factors. There is a challenge in establishing a diagnosis, determining disease activity. Therefore, an important needs is a repertoire of biomarkers that can accurately with prediction, diagnosis, and disease, activity monitoring and stratifying patient. SLE can be diagnosed by using different biomarkers as anti-smith antibodies (ANAS), antibodies to double stand deoxyribonucleic acid (DNA) and level of complement components C3 C4, and CH50. More immunological biomarkers are needed to be better understanding of disease SLE. SLE is an autoimmune disease which can travel to any organ or a system i.e. biomarkers for cardiovascular involvement in SLE, biomarkers for respiratory involvement in SLE, biomarkers for lupus arthritis

Study on Strength and Self-Healing Behaviour of Bio-Concrete

Micro cracks are very commonly observed in concrete structures. Due to increased permeability through these micro cracks, durability of concrete structures reduces by the entry of chemical through these micro pores particularly in moist environments. In the field, crack repair is labour intensive. It is more advisable to restrict the early age small cracks the moment they appear instead of repairing after large cracks formed. In order to increase the durability of concrete against these commonly observed pores in concrete structures, autogenous pore refinement method can be adopted so that monitoring of the structure against these micro pores can be avoided. By using the principle of Biomineralization, Bacteria forms the Calcium precipitations which is usually called microbial induced calcite precipitation (MIC) .In the present work, the bacteria which will grow in the high alkaline media is chosen since concrete is highly alkaline material and cultured in the controlled medium to get the desired concentration of cells. In the present work, Un-identified and Bacillus sphericus bacterial broth is used for the study. It is observed that these bacteria when mixed with concrete at the concentration of 106 cells per ml, the compressive strength is increased by 36.36 % and 13.63 % and for 107 concentrations of cells, the un-identified bacteria show the increase of compressive strength as 29.56 %. Modulus of elasticity of concrete is increased by 23.78 % and 31 % for both bacteria at the concentration of 106 cells per ml of water and Split tensile strength is increased by 23.5 % and 28.5 % for concentration 106 and 107 cells of Bacillus sphericus. SEM and EDAX analysis reveals the deposition of calcium carbonate Keywords: Self-healing, bio mineralization, strengt

Testing General Relativity with Black Hole X-Ray Data and ABHModels

The past 10 years have seen tremendous progress in our capability of testing General Relativity in the strong field regime with black hole observations. 10 years ago, the theory of General Relativity was almost completely unexplored in the strong field regime. Today, we have gravitational wave data of the coalescence of stellar-mass black holes, radio images of the supermassive black holes SgrA$^*$ and M87$^*$, and high-quality X-ray data of stellar-mass black holes in X-ray binaries and supermassive black holes in active galactic nuclei. In this manuscript, we will review current efforts to test General Relativity with black hole X-ray data and we will provide a detailed description of the public codes available on ABHModels.Comment: 31 pages, 5 figures.
