The proposed Deep Underground Neutrino Experiment (DUNE) utilizes a wide-band on-axis tunable muon-(anti)neutrino beam with a baseline of 1300 km to search for CP violation with high precision. Given the long baseline, DUNE is also sensitive to effects due to matter induced non-standard neutrino interactions (NSI) which can interfere with the standard three-flavor oscillation paradigm. Hence it is desirable to design strategies to disentangle effects due to NSI from standard oscillations. In this article, we exploit the tunability of the DUNE neutrino beam over a wide-range of energies to devise an experimental strategy for separating oscillation effects due to NSI from the standard three-flavor oscillation scenario. Using χ 2 analysis, we obtain an optimal combination of beam tunes and distribution of run times in neutrino and anti-neutrino modes that would enable DUNE to isolate new physics scenarios from the standard. We can distinguish scenarios at 3 σ (5 σ ) level for almost all (~50%) values of δ . To the best of our knowledge, our strategy is entirely new and has not been reported elsewhere.

Background Over the last decade, numerous studies have implicated sperm-borne small non-coding RNAs (sncRNAs) in fertility and transgenerational inheritance. Spermatozoa contain a variety of small RNAs; however, inter-individual and inter-population variations in the human sperm sncRNA content (sncRNAome) have not yet been ascertained. Methods We performed sncRNA sequencing in 54 normozoospermic proven fertile Indian donors. We also obtained a second semen sample from 13 donors and a third semen sample from eight donors and repeated sncRNA sequencing. To better understand sperm sncRNAome similarities and variations, sncRNA sequencing data for eligible Chinese ( n  = 87), US ( n  = 14), and Spanish ( n  = 2) normozoospermic (fertile or presumptive fertile) samples were downloaded and analyzed in a uniform manner. sncRNA data were compared within and across populations to identify similarities and differences. Results In Indian samples, rsRNAs (13.71–78.76%), YsRNAs (0.64-76.53%) and tsRNAs (5.63–35.16%) constituted the major fraction and miRNAs, piRNAs, mt-tsRNAs, and other sncRNAs constituted the minor fraction. Across three other populations, rsRNAs (11–80%) and tsRNAs (10–60%) constituted the major fraction, and YsRNAs (0.62–4.28%), miRNAs (0.41–7.37%), piRNAs (1.37–4.36%), mt-tsRNAs (0.14–4.33%), and other sncRNAs constituted the minor fraction. Only 47 miRNAs were consistent across the Indian samples, and only 17 miRNAs were consistent across the four populations. Interestingly, all piRNAs detected in Indian samples were derived from the chromosome 15 piRNA cluster, which were also predominantly present in other populations. tRNA-Gly-GCC contributed approximately 50% of the tsRNA pool across all populations. The mt-tsRNAs also originated majorly from one mt-tRNA that differed across populations. Among the rsRNAs, the maximum number of reads belonged to 28S, followed by 18S, 5S, 5.8S, and 45S in decreasing order. Y4sRNAs were the most abundant YsRNAs, while the second most common contributor differed across populations. Conclusions The human sperm sncRNAome has a ‘core component’ that shows small variations and a ‘peripheral component’ that shows significant variations across individuals and populations. The availability of the normal human sperm sncRNAome would help delineate biologically meaningful variations from sample-to-sample natural/random variations.

A bstract We investigate the physics potential of the upcoming Deep Underground Neutrino Experiment (DUNE) in probing active-sterile mixing. We present analytic expressions for relevant oscillation probabilities for three active and one sterile neutrino of eV-scale mass and highlight essential parameters impacting the oscillation signals at DUNE. We then explore the space of sterile parameters as well as study their correlations among themselves and with parameters appearing in the standard framework ( δ 13 and θ 23 ). We perform a combined fit for the near and far detector at DUNE using GLoBES. We consider alternative beam tune (low energy and medium energy) and runtime combinations for constraining the sterile parameter space. We show that charged current and neutral current interactions over the near and far detector at DUNE allow for an improved sensitivity for a wide range of sterile neutrino mass splittings.

While most of the results of the neutrino oscillation experiments can be accommodated within the standard paradigm of three active flavors, there are tantalizing hints of an eV-scale sterile neutrino from anomalous results of a few short baseline experiments. This additional light sterile neutrino is expected to leave an imprint on the physics observables pertaining to standard unknowns such as determination of the Dirac-type leptonic CP phase, δ 13 , the question of neutrino mass hierarchy and the octant of θ 23 . The upcoming long baseline neutrino experiments such as T2HK, DUNE and P2O will be sensitive to active – sterile mixing. In the present work, we examine and assess the capability of these long baseline experiments to probe the sterile neutrino at the level of probabilities and event rates. We perform a detailed study by taking into account the values of parameters that are presently allowed and (a) study the impact on CP violation by examining the role played by various appearance and disappearance channels, (b) address the question of disentangling the intrinsic effects from extrinsic effects in the standard paradigm as well as three active plus one light sterile neutrino, and finally (c) assess the ability of these long baseline experiments to distinguish between the two scenarios. Our results indicate that for the true values of sterile parameters and for all values of δ 13 , the sensitivity of P2O is the lowest while the sensitivity of T2HK is modest ( < 3 σ ) and the sensitivity of DUNE is > 3 σ . For larger values of the sterile mixing angles, there is an improvement in the sensitivity for all the three considered experiments.

Food security has become a major concern worldwide in recent years due to ever increasing population. Providing food for the growing billions without disturbing environmental balance is incessantly required in the current scenario. In view of this, sustainable modes of agricultural practices offer better promise and hence are gaining prominence recently. Moreover, these methods have taken precedence currently over chemical-based methods of pest restriction and pathogen control. Adoption of Biological Control is one such crucial technique that is currently in the forefront. Over a period of time, various biocontrol strategies have been experimented with and some have exhibited great success and promise. This review highlights the different methods of plant-pathogen control, types of plant pathogens, their modus operandi and various biocontrol approaches employing a range of microorganisms and their byproducts. The study lays emphasis on the use of upcoming methodologies like microbiome management and engineering, phage cocktails, genetically modified biocontrol agents and microbial volatilome as available strategies to sustainable agricultural practices. More importantly, a critical analysis of the various methods enumerated in the paper indicates the need to amalgamate these techniques in order to improve the degree of biocontrol offered by them.

A bstract We formulate an alternative approach based on unitarity triangles to describe neutrino oscillations in presence of non-standard interactions (NSI). Using perturbation theory, we derive the expression for the oscillation probability in case of NSI and cast it in terms of the three independent parameters of the leptonic unitarity triangle (LUT). The form invariance of the probability expression (even in presence of new physics scenario as long as the mixing matrix is unitary) facilitates a neat geometric view of neutrino oscillations in terms of LUT. We examine the regime of validity of perturbative expansions in the NSI case and make comparisons with approximate expressions existing in literature. We uncover some interesting dependencies on NSI terms while studying the evolution of LUT parameters and the Jarlskog invariant. Interestingly, the geometric approach based on LUT allows us to express the oscillation probabilities for a given pair of neutrino flavours in terms of only three (and not four) degrees of freedom which are related to the geometric properties (sides and angles) of the triangle. Moreover, the LUT parameters are invariant under rephasing transformations and independent of the parameterization adopted.

Small non-coding RNAs (sncRNAs), being the top regulators of gene expression, have been thoroughly studied in various biological systems, including the testis. Research over the last decade has generated significant evidence in support of the crucial roles of sncRNAs in male reproduction, particularly in the maintenance of primordial germ cells, meiosis, spermiogenesis, sperm fertility, and early post-fertilization development. The most commonly studied small RNAs in spermatogenesis are microRNAs (miRNAs), PIWI-interacting RNA (piRNA), small interfering RNA (siRNA), and transfer RNA-derived small RNAs (ts-RNAs). Small non-coding RNAs are crucial in regulating the dynamic, spatial, and temporal gene expression profiles in developing germ cells. A number of small RNAs, particularly miRNAs and tsRNAs, are loaded on spermatozoa during their epididymal maturation. With regard to their roles in fertility, miRNAs have been studied most often, followed by piRNAs and tsRNAs. Dysregulation of more than 100 miRNAs has been shown to correlate with infertility. piRNA and tsRNA dysregulations in infertility have been studied in only 3–5 studies. Sperm-borne small RNAs hold great potential to act as biomarkers of sperm quality and fertility. In this article, we review the role of small RNAs in spermatogenesis, their association with infertility, and their potential as biomarkers of sperm quality and fertility.

Assessing the impact of threats, identification, prioritization and predicting conservation pockets are vital for the conservation and management of threatened species. This study investigated the diversity and distribution through inventorization and analysis of International Union for Conservation of Nature (IUCN) categorized threatened plants and their prioritization for conservation. A total of 456 threatened taxa belonging to 233 genera coming under 87 families were recorded as threatened under various threat categories of IUCN. Among lited taxa, 64 species were falls under higher risk of extinction categories of IUCN viz. Critically endangered, Endangered, and Vulnerable with 13, 28 and 23 species respectively. Maximum number of threatened plants was found (84 species) in family Fabaceae followed by Cyperaceae (65 species) and Poaceae (36 species). Richness of threatened plants was found maximum in the Sikkim (203) followed by Himachal Pradesh (190) and Jammu & Kashmir (189). Major causes of depletion of threatened taxa were anthropogenic activities such as habitat loss, overgrazing, deforestation, over-exploitation and unsustainable harvesting of medicinal plants. Therefore, conservation of all the inventorized 64 threatened plants is needful at its earliest. Thus the strategies for the conservation of threatened species must be directed towards those species facing highest risk of extinction, biologically distinct and ecologically valuable for the ecosystem as well having socio-economic significance. Considering this, prioritization of the threatened species was done following existing methodologies. Among the threatened taxa, Angelica glauca, Coptis teeta, Lilium polyphyllum, Nardostachys jatamansi, Aconitum heterophyllum and Gentiana kurroo etc. are ranked at apex, thus needs higher priority for conservation. The study further indicate that six species such as Angelica glauca, Coptis teeta, Gymnocladus assamicus, Illicium griffithii, Piper pedicellatum and Saussurea costus are endemic, having restricted distribution, however highly traded in the IHR. Thus, it is proposed that these species must be taken under special apprehension for conservation planning. Besides this for the conservation of higher risk of extinction species, grid mapping of targeted species was done for identifying specific distribution areas for effective conservation.

Background Spermatogenesis is a temperature-sensitive process, and elevation in temperature hampers this process quickly and significantly. We studied the molecular effects of testicular heating on piRNAs and gene expression in rat testicular germ cells. Methods We generated a cryptorchid rat model by displacing the testis from the scrotal sac (34 °C) to the abdominal area (37 °C) and sacrificed animals after 1 day, 3 days, and 5 days. Pachytene spermatocytes and round spermatids were purified using elutriation centrifugation and percoll gradient methods. We performed transcriptome sequencing in pachytene spermatocytes and round spermatids to identify differentially expressed piRNAs and their probable targets, i.e., TE transcripts and mRNAs. Results As a result of heat stress, we observed significant upregulation of piRNAs and TE transcripts in testicular germ cells. In addition to this, piRNA biogenesis machinery and heat shock proteins (Hsp70 and Hsp90 family members) were upregulated. mRNAs have also been proposed as targets for piRNAs; therefore, we shortlisted certain piRNA-mRNA pairs with an inverse relationship of expression. We observed that in testicular heat stress, the heat shock proteins go hand-in-hand with the upregulation of piRNA biogenesis machinery. The dysregulation of piRNAs in heat-stressed germ cells, increased ping-pong activity, and disturbed expression of piRNA target transcripts suggest a connection between piRNAs, mRNAs, and TE transcripts. Conclusions In heat stress, piRNAs, piRNA machinery, and heat shock proteins are activated to deal with low levels of stress, which is followed by a rescue approach in prolonged stressaccompained by high TE activity to allow genetic mutations, perhaps for survival and adaptability.
