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

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

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

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

Sense of community in on-line, face-to-face, and blended learning contexts

Advances in educational technology leading to the growth of on-line and blended learning contexts as valid alternatives to traditional face-to-face classrooms, as well as recognition that social interactions among learners play a key role in the learning process, has led to an evolution of teaching approaches from direct instruction to facilitated learning. To choose the most appropriate pedagogical approach in the most suitable learning modality, educators need to know which approaches work effectively with the students and why. This mixed-methods research study compared sense of community in on-line, face-to-face and blended learning contexts. Twelve participants, four from each learning context, enrolled in a trades-related training program at a polytechnic reported their sense of community by completing the Classroom Community Scale (CCS) survey. Three participants, one from each learning context, shared their experiences in an interview about how each learning context contributed to their sense of community within the context in which they studied. Likely due to small sample size, survey results showed no statistically significant differences in sense of community between groups. The interviews showed that regular physical contact among students, synchronous discussions, instructor presence, and student-centered pedagogical approaches promote the establishment of sense of community
