Test Sequence Generation for Java7 Fork/Join Using Interference Dependence

Test sequence generation through code is mainly done by using some sort of a flow graph viz. Control Flow Graph (CFG), Concurrent Control Flow Graph (CCFG), Event Graph etc. Approaches that use UML also need flow graph as an intermediate representation for final test sequence generation. In the present approach, a Flow Graph for a new concept i.e. Java7 Fork/Join is constructed and hence, by traversing the graph, test sequences are generated on the basis of all path and all node coverage criteria considering interference dependence. Further, interference dependencies are also represented in the form of a directed graph to aid the analysis of Java7 fork/join programs

Techno-Economic Aspects of Solid Food Wastes into Bio-Manure

Solid waste is health hazard and cause damage to the environment due to improper handling. Solid waste comprises of Industrial Waste (IW), Hazardous Waste (HW), Municipal Solid Waste (MSW), Electronic waste (E-waste), Bio-Medical Waste (BMW) which depend on their supply & characteristics. Food waste or Bio-waste composting and its role in sustainable development is explained in food waste is a growing area of concern with many costs to our community in terms of waste collection, disposal and greenhouse gases. When rotting food ends up in landfill it turns into methane, a greenhouse gas that is particularly damaging to the environment. Composting is biochemical process in which organic materials are biologically degraded, resulting in the production of organic by products and energy in the form of heat. Heat is trapped within the composting mass, leading to the phenomenon of self-heating.This overall process provide us Bio-Manure.

Extended galactic rotational velocity profiles in f(R)f(R) gravity background

An attempt has been made to explore the galactic dynamics via the rotational velocity beyond the Einstein's geometric theory of gravity. It is inspired from the geometric relation obtained in the power law $f(R)$ gravity model in vacuum. We analyse the action with a small positive deviation from the Einstein-Hilbert action (taking $R$ as $f(R)\propto R^{1+\delta}$) at the galactic scales for the explanation of cosmological dark matter problem and obtain the contribution of dynamical $f(R)$ background geometry in accelerating the test mass. In the weak field limits, we obtain the effective acceleration of the test mass due to a massive spherically symmetric source in $f(R)$ background and develop an equation for the rotational velocity. We test the viability of the model by tracing the motion of test mass outside the typical galactic visible boundaries without considering any dark matter halo profile. We obtain a nice agreement in the outer regions (up to few tens of kpc beyond the visible boundary) of the typical galaxy by using the known galaxy data.\\ We further explore the galactic dynamics for a galaxy NGC 1052 of which the dark matter deficient galaxies, i.e., DF2 and DF4 are a part (satellite galaxies) and discuss plots of the dynamical feature of rotation curves in $f(R)$ background for the model parameter $\delta<<1$ and interpret the results for its satellite galaxies.Comment: 7 pages, 5 figure

Light deflection angle through velocity profile of galaxies in f(R)f(R) model

We explore a new realisation of the galactic scale dynamics via gravitational lensing phenomenon in power-law $f(R)$ gravity theory of the type $f(R)\propto R^{1+\delta}$ with $\delta<<1$ for interpreting the clustered dark matter effects. We utilize the single effective point like potential (Newtonian potential + $f(R)$ background potential) obtained under the weak field limit to study the combined observations of galaxy rotation curve beyond the optical disk size and their lensing profile in $f(R)$ frame work. We calculate the magnitude of light deflection angle with the characteristic length scale (because of Noether symmetry in $f(R)$ theories) appearing in the effective $f(R)$ rotational velocity profile of a typical galaxy with the model parameter $\delta \approx O(10^{-6})$ constrained in previous work. For instance, we work with the two nearby controversial galaxies NGC 5533 and NGC 4138 and explore their galactic features by analysing the lensing angle profiles in $f(R)$ background. We also contrast the magnitudes of $f(R)$ lensing angle profiles and the relevant parameters of such galaxies with the generalised pseudo-isothermal galaxy halo model and find consistency.Comment: 7 pages, 5 figure

Epoxyazadiradione exhibit anti‑cancer activities by modulating lncRNAs expression in pancreatic cancer

Background: Azadirachta indica (neem), a medicinal plant under Meliaceae family, is found in the Indian subcontinent. One of the limonoids, epoxyazadiradione (EPA), is a phytochemical isolated from the seeds of this tree. This is widely used in traditional medicine to treat a variety of human ailments. Although EPA has shown promise against some cancer types, its efficacy against pancreatic cancer and the underlying mechanism remains elusive. Aim: We examined the anti‑cancer activity of EPA against pancreatic cancer cells. We also examined the underlying mechanism. Methods: Pancreatic cancer cell lines (PANC-1 and MiaPaCa-2) were used during the study. We performed MTT assay, clonogenic colony formation assay for cytotoxicity. The western blotting was performed to examine the expression pattern of various apoptotic proteins. Real-time PCR was performed to detect quantitative lncRNAs expression. Results and Discussion: After treatment with EPA, the viability and proliferation of pancreatic cancer cells was decreased in a dose- and time-dependent manner. EPA suppressed the expression of apoptotic proteins involved in survival, proliferation, migration and invasion. EPA also suppressed the expression of MMP-9 in a concentration-dependent manner in pancreatic cancer cells. In addition, the limonoid also modulated the expression of lncRNAs (MEG-3, GAS-5, H19 and MHRT). Conclusion: EPA exhibited strong anti-cancer activities against pancreatic cancer by modulating multiple cancer-related signalling molecules

Presentation of an ingested foreign body as a vesical calculus: a common condition, but uncommon presentation

Vesical calculus is a common entity in children of developing countries. Foreign body ingestion is a common occurrence in the pediatric population. An ingested foreign body eroding into the urinary bladder and leading to the formation of a vesical calculus is an extremely rare condition. We encountered a 14-year-old girl who presented with a vesical calculus and a history of ingestion of a nut bolt 7 years earlier. After cystolithotomy and retrieval of the calculus, we noticed that the nut bolt formed its core. As it is an extremely uncommon presentation, it is being reported here, with a brief review of the literature.Keywords: foreign body calculus, foreign body ingestion, vesical calculus, vesicointestinal fistul

A rare cause of kyphosis with low backache - “Scheuermann’s disease”: “Osteochondritis deformans juvenilis dorsi”

An uncommon case of Scheuermann’s disease (Apprentice’s spine) is being reported for two simple reasons- firstly, to show that it is a self-limiting disease which needs only proper observation, extension exercises & extension spinal brace and secondly, it becomes a diagnostic riddle when osteolytic lesion is seen in epiphyseal plates of adjacent vertebral bodies in an adolescent. Radiology and Imaging are needed for the early and accurate diagnosis and to differentiate it from other causes of kyphosis. Hence, it stressed the need to publish this condition not only for its rarity but also for its diagnostic puzzle to differentiate it from other conditions. Here we report a case of an adolescent male of 17 years with poor posture/slouching, fatigue, mild pain in lower thoracic area of spine (low backache), stiffness and loss of flexibility with radiological and MRI findings

Probing massive gravitons in f(R)f(R) with lensed gravitational waves

We investigate the novel features of gravitational wave solutions in $f(R)$ gravity under proper gauge considerations in the shifted Ricci scalar background curvature ($R^{1+\epsilon}$). The solution is further explored to study the modified dispersion relations for massive modes at local scales and to derive constraints on $\epsilon$. Our analysis yields new insights as we scrutinize these dispersion effects on the polarization (modified Newman-Penrose content) and lensing properties of gravitational waves. It is discovered that the existing longitudinal scalar mode, and transverse breathing scalar mode are both independent of the mass parameter for $\epsilon<<1$. Further, by analysing the lensing amplification factor for the point mass lens model, we show that lensing of gravitational wave is highly sensitive to these dispersion effects in the milli-Hertz frequency (wave optics regime). It is expected that ultra-light modes, having mass about $\mathcal{O} (10^{-15})$ eV for $\epsilon<<1 (\approx 10^{-7})$ lensed by ($10^3\leq M_{Lens}\leq 10^6$)$M_\odot$ compact objects are likely to be detected by the advanced gravitational wave space-borne detectors, particularly within LISA's (The Laser Interferometer Space Antenna) sensitivity band.Comment: 16 pages, 10 figure
