    Invariant and screen semi-invariant lightlike submanifolds of a metallic semi-Riemannian manifold with a quarter symmetric non-metric connection

    Full text link
    This research work introduces the structure of invariant and screen semi-invariant lightlike submanifolds of a metallic semi-Riemannian manifold with a quarter symmetric non-metric connection, elaborated with examples. It delves into the characterization of integrability and parallelism of distributions inherent in the structure of these submanifolds. Additionally, it presents findings pertaining to totally geodesic foliations for invariant and screen semi-invariant submanifolds

    Effects of Arbuscular Mycorrhizal Fungi (AMF) on Growth and Herbivore Defenses in Sorghum Sudangrass (Sorghum X drummondii)

    Chapter 2: In this chapter we have examined the role of trichomes in plant stress biology, reviewed the studies on herbivore X trichome interactions, and their role in plant defences. Ultimately, we have proposed new areas of research for future work. Chapter 3: In this chapter, we examined whether AMF has cascading effects on insect community dynamics through attraction/repulsion of beneficial and damaging insects using Sorghum-sudangrass (Sorghum x drummondii), either inoculated with commercial AMF mix or left as control in lab and field experiments. Our results suggest positive effects of AMF on plant growth, and a lower initial incidence of fall armyworm (Spodoptera frugiperda), a major herbivore on Sorghum in the region. Besides, AMF inoculated plants attracted significantly more beneficial insects (predators and parasitoids) and a lower number of damaging herbivores. Therefore, our data suggests that AMF can have implications for sustainable pest management strategies

    Bone Marrow Stroma-induced Transcriptome Signatures of Multiple Myeloma as Modulated by JUNB

    The bone marrow (BM) microenvironment acts as a breeding ground for drug resistance in multiple myeloma (MM). The interaction with bone marrow stromal cells (BMSCs) confer environment-mediated drug resistance (EMDR) to multiple myeloma. We investigated BM stroma-induced transcriptome signatures of MM cells through a sophisticated analysis of gene expression. In particular, we defined transcription program modulated by JunB, an emerging regulator of MM pathogenesis and a member of the transcription factor superfamily activator protein 1 (AP-1), in response to BM stimulation. The data and results lay down a foundation for future studies to illustrate the regulatory role of JunB in the de novo drug resistance of multiple myeloma

    Modeling urbanization patterns with generative adversarial networks

    Full text link
    In this study we propose a new method to simulate hyper-realistic urban patterns using Generative Adversarial Networks trained with a global urban land-use inventory. We generated a synthetic urban "universe" that qualitatively reproduces the complex spatial organization observed in global urban patterns, while being able to quantitatively recover certain key high-level urban spatial metrics.Comment: 4 pages, 4 figure

    Twin-Twin transfusion syndrome: a case report

    Get PDF
    Twin to twin transfusion syndrome is a rare but serious complication of monochorionic twin pregnancy. It is characterized by the development of abnormal placental vascular communication from one foetus (donor) to the other foetus (recipient). If left untreated it led to high rates of perinatal morbidity and mortality due to its poorly understood etiology and difficulty in diagnosing and treatment. Authors report a case of twin to twin transfusion syndrome in 24 years old primigravida with gestational age of 18 weeks 5 days diagnosed on ultrasound

    Trends in Over-the-top (OTT) Video Services in Asian Countries- A Systematic Review of Literature

    Get PDF
    Consumer media consumption habits have changed significantly as a result of the introduction of over-the-top video (OTT) services. While the market for streaming services in the West seems to be saturated, Asia still has room for growth. Asia is a complex market with a mix of international, regional, and local streaming services, with ownership often coming from a telecoms player, media corporation, or broadcaster. Despite the immense growth of OTT video services, there still has been very limited research done in this area. The purpose of the study is to investigate the current trends in OTT research by synthesizing the available literature and to identify the research areas in the context of OTT that could be pursued in the future. This study provides a systematic review of 26 research articles published on OTT video services between 2017 to 2022 in the context of Asian countries. It classifies the literature in terms of years, countries, theories and models used or variables identified, research methods, findings and implications or suggestions. The study implies that the future research on OTT should explore the perspective of service providers anad regulatory bodies as well
