We propose a scheme of controlled entanglement diversion of a bi-partite entangled coherent state using GHZ type entangled coherent state as a resource. The scheme involves only linear optical devices such as phase shifters, beam splitters and photon counters. Average fidelity of diversion is calculated and plotted. It is 2/3 for very small coherent amplitudes and approaches unity for appreciable coherent amplitude. [ABSTRACT FROM AUTHOR]

We study maximum simultaneous 2 n th-order Hong and Mandel's squeezing of the most general the Hermitian operator, X θ ≡ X 1 cos θ + X 2 sin θ , and n th-order sub-Poissonian photon statistics (connected with expectation value of 2 n th power of number fluctuation), in the most general superposition state, ψ = Z 1 α + Z 2 β of two coherent states α and β . Here Hermitian operators X 1,2 are defined by X 1 + iX 2 = a , the annihilation operator, complex numbers Z 1,2 , α , β are all arbitrary and the only restriction on these is the normalization condition of the state. We find a linear relationship between these two non-classical effects when the angle θ = arg( α + β ) and α + β ≫ α − β . We show that maximum simultaneous 2 n th-order Hong and Mandel's squeezing for the operator X θ and n th-order sub-Poissonian photon statistics in the state occur for an infinite combinations with α − β = A 2 n exp ± i 1 / 2 π + i θ ; A 2 n is a constant which depends on the order of squeezing, Z 2 / Z 1 = exp 1 / 2 ( β α * − β * α ) and with θ = arg( α + β ) and α + β ≫ α − β . We also illustrate analytically and numerically by an example that both effects occur simultaneously for high-intensity field but for observation of such effects, sensitive settings of the parameters are required.

Present work is an attempt to compare quantum discord and quantum entanglement of quasi-Werner states formed with the four bipartite entangled coherent states (ECS) used recently for quantum teleportation of a qubit encoded in superposed coherent state. Out of these, the quasi-Werner states based on maximally ECS due to its invariant nature under local operation is independent of measurement basis and mean photon numbers, while for quasi-Werner states based on non-maximally ECS, it depends upon measurement basis as well as on mean photon number. However, for large mean photon numbers since non-maximally ECS becomes almost maximally entangled therefore dependence of quantum discord for non-maximally ECS based quasi-Werner states on the measurement basis disappears.

The idea of secure quantum information exchange (SQIE) [ J. Phys. B: At. Mol. Opt. Phys. 44, 115504 (2011)] is introduced for the secure exchange of single qubit information states between two legitimate users, Alice and Bob. In the present paper, we extend this original SQIE protocol by presenting a scheme, which enables the secure exchange of n-single qubit information states among the n nodes of a quantum network, with the aid of a special kind of 4 n-qubit entangled state and the classical assistance of an extra participant Charlie. For experimental realization of our extended SQIE protocol, we suggest an efficient scheme for the generation of a special kind of 4 n-qubit entangled state using the interaction between highly detuned Λ-type three-level atoms and optical coherent field. Further, by discussing the various experimental parameters, we show that the special kind 4 n-qubit entangled state can be generated with the presently available technology. [ABSTRACT FROM AUTHOR]

Recently, Aliloute et al. [Quantum Inf Process 20, 29 (2021)] proposed a scheme of bidirectional quantum teleportation of coherent state qubit using three-mode entangled coherent state as a resource with success probability 1/2. However, their scheme is not feasible due to some shortcomings. In this present work, we propose a scheme of bidirectional quantum teleportation of coherent state qubit between two distant partners Alice and Bob, with the consent of controller, Charlie. We use five-mode cluster-type entangled coherent state as the quantum resource to achieve this task. The scheme uses linear optical devices such as beam splitters, phase shifters, and photon counters. It is shown that for moderately large coherent amplitude, near perfect controlled bidirectional quantum teleportation can be obtained in terms of the average fidelity of teleportation.

Developing pure diastereoisomeric molecular hybrids for the selective inhibition of bacterial growth opened new avenues for combating the ever-increasing microbial resistance. Considering this, a series of diastereoisomeric pure pyrazolyl-dihydrofurans (7a-7y) were synthesized and characterized using NMR, LCMS, and X-ray crystallography. DFT based method was used to explore the configurational stability of cis over trans isomeric form. Considering 7a and 8a as representative isomeric forms with same structural framework, the difference in their bio-efficacy against bacterial and fungal strains was assessed using serial dilution method. The relatively high inhibition of bacterial growth by the cis isomeric form (7a) (MIC = 1.562 µg/mL), amoxicillin (MIC = 3.125 µg/mL) inspired us to broaden the substrate scope for synthesizing a series of pure diastereoisomeric cis forms as selective anti-bacterial agents. However, both the isomers displayed antifungal activity less than the standard drug (Fluconazole) employed in the study. All the reactions proceeded smoothly and yielded a diverse array of dihydrofuran derivatives. The developed synthetics were found to be non-cytotoxic against mouse fibroblast cells and didn't affect the seed germination of Brassica nigra seeds when treated at 1 mg/mL concentration. The experimentally determined in vitro results were further validated using in silico molecular docking and dynamics studies., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

Background: Diabetes is a chronic medical condition with severe complications, mainly caused by unhealthy lifestyles in genetically susceptible individuals. There has been a growing interest in the role of mobile health technologies in achieving better self-efficacy in managing diabetes. This study attempts to assess the impact of a web-based model on improving the diabetes status among Type 2 diabetic patients attending a tertiary care hospital in southern India., Methods: A longitudinal study was conducted among patients with type 2 diabetes attending the outpatient department of a tertiary care hospital in Mysuru, southern India, for 6 months. Diabetes Care (https://www.diabetes-care.co.in/), which is an online website that can be used as a risk prediction tool for uncontrolled diabetes and recommends lifestyle changes, was used by 456 diabetes patients for 6 months. We assessed the change in glycosylated haemoglobin levels at the beginning and after 6 months of using the software., Results: The mean HbA1c value at the start of the study was 8.039% ± 1.981. The HbA1c value assessed after 6 months post-intervention showed an improvement of 7.794% ± 1.853 with a mean difference of 0.245. A paired T-test showed a statistically significant association with a P value of 0.049., Conclusions: Evidence from this study suggests that intervention using a web-based model focusing on risk prediction and educational intervention showed an improvement in the diabetic status of the patients with T2DM., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 International Journal of Preventive Medicine.)

Objectives: We evaluated trends in hypertension prevalence, awareness, treatment and control in an Indian urban population over 25 years. Trends were projected to year 2030 to determine attainment of World Health Organization (WHO) Global Monitoring Framework targets., Methods: Adult participants (n=7440, men 4237, women 3203) enrolled in successive population based studies in Jaipur, India from years 1991 to 2015 were evaluated for hypertension prevalence, awareness, treatment and control. The studies were performed in years 1991-93 (n=2212), 1999-01 (n=1123), 2003-04 (n=458), 2006-07 (n=1127), 2009-10 (n=739) and 2012-15 (n=1781). Descriptive statistics are reported. We used logarithmic forecasting to year 2030 and compared outcomes to WHO target of 25% lower prevalence and >50% control., Results: The age-adjusted hypertension prevalence (%) among adults in successive studies increased from 29.5, 30.2, 36.5, 42.1, 34.4 to 36.1 (R 2 =0.41). Increasing trends were observed for hypertension awareness (13, 44, 49, 44, 49, 56; R 2 =0.63); treatment in all (9, 22, 38, 34, 41, 36; R 2 =0.68) and aware hypertensives (61, 66, 77, 79, 70, 64; R 2 =0.46); and control in all (2, 14, 13, 18, 21, 21; R 2 =0.82), aware (12, 33, 27, 46, 37, 37; R 2 =0.54) and treated (9, 20, 21, 48, 36, 49; R 2 =0.80) hypertensive participants. Projections to year 2030 show increases in prevalence to 44% (95% CI 43-45), awareness to 82% (81-83), treatment to 62% (61-63), and control to 36% (35-37)., Conclusion: Hypertension prevalence, awareness, treatment and control rates are increasing among urban populations in India. Better awareness is associated with greater control. The rates of increase are off-target for WHO Global Monitoring Framework and UN Sustainable Development Goals., (Copyright © 2017.

Objective: The impact of rising population-wide obesity on cardiovascular risk factors has not been well studied in low-income countries. To correlate the prevalence of obesity with risk factors we performed epidemiological studies in India., Methods: Multiple cross-sectional epidemiological studies, Jaipur Heart Watch (JHW), were performed in India in rural and urban locations. From these cohorts, subjects aged 20-59 years (men 4102, women 2872) were included. Prevalence of various risk factors: smoking/tobacco use, overweight/obesity (body mass index > or = 25 kg/m2) truncal obesity (waist:hip > or = 0.95 men, > or = 0.85 women), hypertension, dyslipidemias, metabolic syndrome and diabetes was determined. Trends were examined using least squares regression., Results: Smoking/tobacco use was more in rural men (50.0% vs 40.6%) and urban women (8.9% vs 4.5%, p < 0.01). Obesity, truncal obesity, hypertension, hypercholesterolemia, diabetes, and metabolic syndrome were more in urban cohorts (p < 0.001). Age-adjusted prevalence (%) of obesity in various cohorts, rural JHW, and urban JHW-1, JHW-2, JHW-3, and JHW-4 respectively, in men was 9.4, 21.1, 35.6, 54.0, and 50.9 (r2 = 0.92, p = 0.009) and in women 8.9, 15.7, 45.1, 61.5, and 57.7 (r2 = 0.88, p = 0.018). Prevalence of truncal obesity in men was 3.2, 19.6, 39.6, 41.4, and 31.1 (r2 = 0.60, p = 0.124) and in women 10.1, 49.5, 42.1, 51.7, and 50.5 (r2 = 0.56, p = 0.1467). In successive cohorts increasing trends were observed in the prevalence of hypertension (r2 = 0.93, p = 0.008) and metabolic syndrome (r2 = 0.99, p = 0.005) with weaker trends for hypercholesterolemia (r2 = 0.41, p = 0.241) and diabetes (r2 = 0.79, p = 0.299) in men. In women, significant trends were observed for hypertension (r2 = 0.98, p = 0.001) and weaker trends for others. Increase in generalized obesity correlated significantly with hypertension (two-line regression r2, men 0.91, women 0.88), hypercholesterolemia (0.53, 0.44), metabolic syndrome (0.87, 0.94) and diabetes (0.84, 0.93). Truncal obesity correlated less strongly with the risk factors like hypertension (0.50, 0.57), hypercholesterolemia (0.88, 0.61), metabolic syndrome (0.76, 0.33), and diabetes (0.75, 0.33)., Conclusions: In Asian Indian subjects, escalating population-wide generalized obesity correlates strongly with increasing cardiovascular risk factors.

Purpose: Recently available Ceromer resin materials are promising for fabrication of esthetic anterior laminates and provices an alternative, cost effective treament modality to porcelain laminates for discolored anterior anterior teeth. It was proposed to study the esthetic quality and surface finish of veneers fbricated from ceromer resin and compare it with the standard porcelain veneers, both clinically as well as by scanning electron microscope (SEM) at baseline and at 12 months. If found comparable, ceromer resin veneer could provide an alternative to porcelain veneers which is an expensive technique for a developing country like India., Materials and Methods: Seventy-two veneers, 36 porcelain and 36 ceromer were placed in 12 subjects who were studied at 0, 6 and 12 months for clinical acceptability, and at 0 and 12 months for SEM assessment. The restorations were luted with Opal luting composite and Scotchbond multipurpose system; polyvinyl siloxane was used as the impression material. The clinical assessment was made using modified United Public Health Services criteria, whereas the SEM assessment was made by quantitative analysis of the marginal fit and surface characteristics of the two veneering materials., Results: Ceromer exhibited good anatomical form during the study period, but depicted changes in color, surface appearance, marginal adaptation, increased marginal discoloration, and tissue response. Inability to achieve a good finish with high gloss was a major drawback of the ceromer. Porcelain exhibited better esthetics, marginal adaptation, finish qualities, and tissue response. The SEM showed good to excellent marginal fit at baselinne in ceromer and porcelain veneers, but loss of luting resin at the margins was evident in both the materials after 12 months, leading to visible gaps in a number of veneer restorations. Ceromer veneers exhibited poor surface characteristics in several restorations, which further degraded in an oral conditions over 12 months., Conclusion: Veneering is an effective mode of treating discolored teeth. Ceromer veneers exhibited deterioration of surface finish and increased marginal discolouration over a period of 12 months. Clinically ceromer veneers were less acceptable to the patients than porcelain veneers. Porcelain out-scored ceromer as a permanent mode of treatment for discolored teeth, as over a period of 12 months it yielded good clinical results in comparison to ceromer.
