Abstract	This book is the result of comprehensive research work on the various aspects of the West Bengal coast including the world’s largest riverine delta system, the Ganga-Brahmaputra Delta. The role of various hydrodynamic factors in shaping the coastal configuration and physicochemical parameters of coastal waters, soils, and granulometry of beach sands are extensively discussed. The coasts of the Indian peninsula, particularly the east coast, are subjected to severe cyclones, tidal bores, storm surges, and strong drift, which changes the coastal configuration as well as the quality of waters and the fertility of soils. A systematic description of major cyclones and their effects on coastal areas are described in detail. The book offers comprehensive information on the prevailing ecological conditions and lush green mangrove forests with wide-ranging flora and fauna of Sundarbans. UNESCO has declared Sundarbans as one of the world’s heritage sites, and as in other parts of the world, some of the coastal areas in West Bengal have attracted the attention of many tourists. Various steps undertaken by the government for coastal zone management and sustainable development of the coastal areas have been highlighted in the book. This book will be of interest to students and researchers of the coastal environment.

Abstract	Purpose: In patients with symptomatic osteoarthritis knee (OAK), cryoneurolysis (CRYO) and cooled radiofrequency ablation (C-RFA) are reported to be effective and safe; however, they have not been compared directly. The objective of this study is to compare CRYO and C-RFA of the genicular nerve (GN) in terms of efficacy and safety profile in patients with Kellgren and Lawrence (KL) grade ≥ 3 OAK. Methods: This single-centric, assessor-blinded, randomized, parallel-group, non-inferiority study will include 80 patients with KL grade ≥ 3 OAK. The patients with ≥ 50% pain relief on diagnostic block of three GNs will be randomized to one of the two groups, i.e., CRYO (n = 40) or C-RFA (n = 40). The three target GNs for the interventions will include: superior medial, superior lateral, and inferior medial. The primary outcome will be efficacy of CRYO or C-RFA at 2, 12, and 24 weeks post-procedure based on the 11-point Numerical Pain Rating Scale. The secondary outcomes will be functional improvement based on 12-item Oxford Knee Score and safety of both the procedures. The study is registered in the Clinical Trials Registry-India. Conclusion: CRYO and C-RFA provide pain relief and improve functional outcome by preventing transmission of pain signals, though by distinct mechanisms. While C-RFA is an established treatment modality, recent evidence supports CRYO in patients with OAK. This study intends to demonstrate non-inferiority of CRYO against C-RFA, thereby supporting the use of CRYO as an additional treatment modality in patients with KL grade ≥ 3 OAK.

Abstract	Similarity measurement is the determination of the properties of communities that helps to suggest whether the communities may be classified together or in necessity to be separated in the field of modern ecology. Similarity index sometimes is estimated reformulating the indices of abundance coefficients. Estimation of abundances applying different statistical methods like Jaccard and Sorensen's indices, similarity percentage, Morisita-Horn's indices etc is an important way to characterize and measure the properties of plant communities as the species abundances comprise the community. Alike abundances, similarity, a parameter, is utilized for the interpretation of the communities in necessity. Measurement of such similarity indices as a community parameter has been attempted in the forest stands of Chilapata and Mendabari forest stands of Dooars in the state of West Bengal. The obtained results show the estimated values 0.92 and 0.96 for the Adjusted Jaccard and Adjusted Sorensen indices respectively which are the best choices and preferred for the measurements of the estimation of similarity index because of their identical low biased measuring patterns among presence-absence and abundance based similarity measuring indices.

Abstract	Opioids have been the mainstay for pain relief and palliation over a long period of time. They are commonly abused by drug addicts and such dependence usually imparts severe physiologic effects on multiple organ systems. The negative impact of opioids on the endocrine system is poorly understood and often underestimated. We describe a patient who developed severe suppression of the hypothalamic-pituitary adrenal (HPA) axis leading to secondary adrenal insufficiency due to long standing abuse of opioids.

Abstract	Linear Regression is a seminal technique in statistics and machine learning, where the objective is to build linear predictive models between a response (i.e., dependent) variable and one or more predictor (i.e., independent) variables. In this paper, we revisit the classical technique of Quantile Regression (QR), which is statistically a more robust alternative to the other classical technique of Ordinary Least Square Regression (OLS). However, while there exist efficient algorithms for OLS, almost all of the known results for QR are only weakly polynomial. Towards filling this gap, this paper proposes several efficient strongly polynomial algorithms for QR for various settings. For two dimensional QR, making a connection to the geometric concept of $k$-set, we propose an algorithm with a deterministic worst-case time complexity of $\mathcal{O}(n^{4/3} polylog(n))$ and an expected time complexity of $\mathcal{O}(n^{4/3})$ for the randomized version. We also propose a randomized divide-and-conquer algorithm -- RandomizedQR with an expected time complexity of $\mathcal{O}(n\log^2{(n)})$ for two dimensional QR problem. For the general case with more than two dimensions, our RandomizedQR algorithm has an expected time complexity of $\mathcal{O}(n^{d-1}\log^2{(n)})$.

Abstract	Background The vertebral arteries (VA) nourish the posterior cerebral circulation. Planning neck and cervical interventions like drilling and instrumentation, which involves VA manipulation, require an in-depth acquaintance with the normal and variant patterns encountered in the origin and course of the VA. Embryological events involved in forming these variant patterns can be correlated to their prior disposition in the lower vertebrate's understanding which becomes crucial while planning cervical interventions. Study design This is a single-center, retrospective study. Materials and methods The study involved 70 patients of both sexes and was done from September 2021 to February 2022 in the Department of Radiodiagnosis and Imaging at North Eastern Indira Gandhi Regional Institute of Health and Medical Sciences (NEIGRIHMS), Meghalaya, India. The CT angiographies were studied for variations of VA under V1 - from origin to entrance into the foramen transversarium (FT), V2 - part inside FT, V3 - from its exit from FT till it pierces the cranial dura mater, and V4 - intracranial part. Further, VA was observed for its origin, dominance, level of entry in FT, and any associated anomalies. Results The VA was found mostly to be codominant. There was an opposite directional relationship between the basilar artery curvature and the dominance of VA. The association of ischemic events with hypoplastic VA was more on the left side (66.67%). Left VA originated from the aorta in 4.3% of subjects. One case presented a dual origin of VA. The abnormal origin of the LVA from the aorta showed a higher rate of abnormal entry into FT which was also found to be statistically significant. Conclusion Our study identifies and documents the anatomical variations present in VA specific to the population of northeast India by CT angiography and thus provides a much-needed reference for the healthcare professionals working in the field of Head and Neck interventions by providing opportunities further to understand these patterns for better diagnostic and therapeutic outcomes.

Abstract	This manuscript reports the whole genome sequence of a conditionally pathogenic rhizobacterial strain, Pseudomonas putida AKMP7, which has been previously reported by us to be beneficial to Arabidopsis thaliana under well-watered conditions and pathogenic to the plant under water stress. As part of a study to understand this unique behavior, the whole genome sequence of this strain was analyzed. Based on the results, it was identified that the total length of the AKMP7 genome is 5,764,016 base pairs, and the total GC content of the genome is 62.93% (typical of P. putida). Using RAST annotation pipeline, it was identified that the genome has 5605 coding sequences, 80 repeat regions, 71 tRNA genes, and 22 rRNA genes. A total of 4487 functional proteins and 1118 hypothetical proteins were identified. Phylogenetic analysis has classified it as P. putida species, with a P value of 0.03. In order to identify close relatives of this strain, comparative genomics was performed with 30 other P. putida strains, taken from publicly available genome databases, using Average Nucleotide Identity (ANI) analysis. Whole genome comparison with these strains reveals that AKMP7 possesses Type-IV Secretion System (T4SS) with conjugative transfer functionality. Interestingly, the T4SS feature is absent in all the beneficial/harmless strains of P. putida that we analyzed. All the plant pathogenic bacteria that were analyzed had the T4SS feature in their genome, indicating its role in pathogenesis. This study aims to address important gaps in understanding the molecular mechanisms involved in the conditional/opportunistic pathogenesis of plant-associated, beneficial soil bacteria, using genomics approaches.

Abstract	Background and aims: Intra-articular steroids provide significant pain relief in sacroiliac joint pain (SIJP), but their action is short-lived. Cryoneurolysis is reported to produce prolonged pain relief in various pain conditions. However, its efficacy has not been evaluated in patients with SIJP. Thus, we compared the efficacy of cryoneurolysis with steroid injections in adult patients with SIJP. Methods: This retrospective healthcare records review-based study involved 83 patients with SIJP. Patients were divided into two groups: cases (sacroiliac joint [SIJ] cryoneurolysis, Results: Both cases and controls showed significantly decreased NPRS scores from baseline to immediately, 1 month, 3 months and 6 months postintervention ( Conclusion: Although both cryoneurolysis and intra-articular steroid injections provide significant pain relief immediately, 1, 3 and 6 months postintervention, cryoneurolysis resulted in significantly greater pain relief.
