Comprehensive Genome-Wide Analysis and Expression Pattern Profiling of PLATZ Gene Family Members in Solanum Lycopersicum L. under Multiple Abiotic Stresses

PLATZ (plant AT-rich sequence and zinc-binding) family proteins with two conserved zinc-dependent DNA-binding motifs are transcription factors specific to the plant kingdom. The functions of PLATZ proteins in growth, development, and adaptation to multiple abiotic stresses have been investigated in various plant species, but their role in tomato has not been explored yet. In the present work, 20 non-redundant Solanum lycopersicum PLATZ (SlPLATZ) genes with three segmentally duplicated gene pairs and four tandemly duplicated gene pairs were identified on eight tomato chromosomes. The comparative modeling and gene ontology (GO) annotations of tomato PLATZ proteins indicated their probable roles in defense response, transcriptional regulation, and protein metabolic processes as well as their binding affinity for various ligands, including nucleic acids, peptides, and zinc. SlPLATZ10 and SlPLATZ17 were only expressed in 1 cm fruits and flowers, respectively, indicating their preferential involvement in the development of these organs. The expression of SlPLATZ1, SlPLATZ12, and SlPLATZ19 was up- or down-regulated following exposure to various abiotic stresses, whereas that of SlPLATZ11 was induced under temperature stresses (i.e., cold and heat stress), revealing their probable function in the abiotic stress tolerance of tomato. Weighted gene co-expression network analysis corroborated the aforementioned findings by spotlighting the co-expression of several stress-associated genes with SlPLATZ genes. Confocal fluorescence microscopy revealed the localization of SlPLATZ–GFP fusion proteins in the nucleus, hinting at their functions as transcription factors. These findings provide a foundation for a better understanding of the structure and function of PLATZ genes and should assist in the selection of potential candidate genes involved in the development and abiotic stress adaptation in tomato.
Reason Behind Living in a Disaster-Prone Coastal Region: A case study on Sarankhola Upazila, Bangladesh

due unable their economic stability strike. While migration is a common scenario in such situations, most of the people are still living in these areas and there is a significant Abstract: While the entire world is concerned about climate change and natural disasters, disaster-prone developing countries are struggling to keep pace with developments due to frequent natural disasters. Countries like Bangladesh which have a 700 km long exposed funnel-shaped southern-coastal shoreline and disaster-prone geographical location, experience increased vulnerability to natural disasters every year. Despite being vulnerable to frequent natural disasters, people are still living in these coastal areas let alone evacuating the region. Even after severe disaster strikes, very few people are intended to migrate from their place, where the larger share remains in their places despite vulnerabilities. The southern coastal region of Bangladesh is no different, and people who are living in these regions are struggling with frequent natural disasters along with extreme poverty. Despite being a hostile place for living in terms of coastal natural disasters, the region never remains devoid. In contrast, it has a vibrant livelihood diversification, a small but thriving economy, and innovative adaptation measures to coastal disaster vulnerabilities. This research paper aims to contribute to the relevant literature by identifying the reasons and factors that make the people stay in their place, despite frequent disaster phenomena. This research paper brings a closer look into the challenges, adaptation mechanisms, and factors that are turning a disaster-prone coastal region into an inhabitable and economically vibrant place to live in. back migration after a they and indigenous coping-up strategies, and some institutional help.

To determine representative sample size, the formula proposed by Yamane (1967) has been used.
An iterative reconstruction method for high-pitch helical luggage CT

X-ray luggage CT is widely used in airports and railway stations for the purpose of detecting contrabands and dangerous goods that may be potential threaten to public safety, playing an important role in homeland security. An X-ray luggage CT is usually in a helical trajectory with a high pitch for achieving a high passing speed of the luggage. The disadvantage of high pitch is that conventional filtered back-projection (FBP) requires a very large slice thickness, leading to bad axial resolution and helical artifacts. Especially when severe data inconsistencies are present in the z-direction, like the ends of a scanning object, the partial volume effect leads to inaccuracy value and may cause a wrong identification. In this paper, an iterative reconstruction method is developed to improve the image quality and accuracy for a large-spacing multi-detector high-pitch helical luggage CT system. In this method, the slice thickness is set to be much smaller than the pitch. Each slice involves projection data collected in a rather small angular range, being an ill-conditioned limited-angle problem. Firstly a low-resolution reconstruction is employed to obtain images, which are used as prior images in the following process. Then iterative reconstruction is performed to obtain high-resolution images. This method enables a high volume coverage speed and a thin reconstruction slice for the helical luggage CT. We validate this method with data collected in a commercial X-ray luggage CT.
Inflammatory Cytokines That Enhance Antigen Responsiveness of Naïve CD8+ T Lymphocytes Modulate Chromatin Accessibility of Genes Impacted by Antigen Stimulation

Naïve CD8+ T lymphocytes exposed to certain inflammatory cytokines undergo proliferation and display increased sensitivity to antigens. Such ‘cytokine priming’ can promote the activation of potentially autoreactive and antitumor CD8+ T cells by weak tissue antigens and tumor antigens. To elucidate the molecular mechanisms of cytokine priming, naïve PMEL-1 TCR transgenic CD8+ T lymphocytes were stimulated with IL-15 and IL-21, and chromatin accessibility was assessed using the assay for transposase-accessible chromatin (ATAC) sequencing. PMEL-1 cells stimulated by the cognate antigenic peptide mgp10025-33 served as controls. Cytokine-primed cells showed a limited number of opening and closing chromatin accessibility peaks compared to antigen-stimulated cells. However, the ATACseq peaks in cytokine-primed cells substantially overlapped with those of antigen-stimulated cells and mapped to several genes implicated in T cell signaling, activation, effector differentiation, negative regulation and exhaustion. Nonetheless, the expression of most of these genes was remarkably different between cytokine-primed and antigen-stimulated cells. In addition, cytokine priming impacted the expression of several genes following antigen stimulation in a synergistic or antagonistic manner. Our findings indicate that chromatin accessibility changes in cytokine-primed naïve CD8+ T cells not only underlie their increased antigen responsiveness but may also enhance their functional fitness by reducing exhaustion without compromising regulatory controls.
Dynamical magnetic susceptibilities in copper benzoate

Recent experiments on the quasi 1-D antiferromagnet Cu Benzoate revealed a magentic field induced gap coexisting with (ferro)magnetic order. A theory explaining these findings has been proposed by Oshikawa and Affleck. In the present work we discuss consequences of this theory for inelastic neutron scattering experiments by calculating the dynamical magnetic susceptibilities close to the antiferromagnetic wave vector by the formfactor method.
Quantum states for Heisenberg-limited interferometry

The phase sensitivity of interferometers is limited by the so-called Heisenberg limit, which states that the optimum phase sensitivity is inversely proportional to the number of interfering particles N, a 1/{radical}(N) improvement over the standard quantum limit. We have used simulated annealing, a global optimization strategy, to systematically search for quantum interferometer input states that approach the Heisenberg-limited uncertainty in estimates of the interferometer phase shift. We compare the performance of these states to that of other nonclassical states already known to yield Heisenberg-limited uncertainty.
Long-Term Diet Quality and Risk of Diabetes in a National Survey of Chinese Adults

There is little evidence involving the association between diet quality and the risk of diabetes among the Asian populations, especially from the long-term prospective cohort studies in China. This study evaluated the long-term diet quality of Chinese adults by the Chinese diet balance index 2016 (DBI-16) and firstly explored its role in diabetes prevention. A total of 9394 participants from the China health and nutrition survey (2004–2015) prospective cohort were included. Dietary information was selected by three consecutive 24-h dietary recalls, combined with a household food inventory and further calculated as the scores of the DBI-16 components and indicators. Three major indicators, the low bound score (LBS), the high bound score (HBS) and the diet quality distance (DQD), were divided into four level groups, according to the total scores, respectively, including Level 1 (scores below 20%), Level 2 (20–40% of scores), Level 3 (40–60% of scores) and Level 4 (scores above 60%). Diabetes cases were identified through a questionnaire or by testing the overnight fasting blood samples. Cox’s proportional hazards models were used to estimate the hazard ratios (HRs) and 95% CIs, while restricted cubic splines (RCS) were applied to explore the potentially non-linear relationships. During a median follow-up of 6.0 years (61,979 persons-years), 657 participants developed diabetes. The LBS and DQD scores were positively associated with diabetes risks, whereas no significant association of the HBS scores with diabetes risks was observed. Compared with those on the lowest level, the adjusted HRs (95%) across the increased levels of diet quality were 2.43 (1.36, 4.37), 3.05 (1.69, 5.53) and 4.90 (2.46, 9.78) for the LBS; 1.06 (0.74, 1.51), 1.30 (0.99, 1.88) and 0.99 (0.39, 2.55) for the HBS; 1.28 (1.01, 1.61) and 2.10 (1.57, 2.82) for the DQD after pooling the participants on Level 1 and 2 as the reference group, due to the few who developed diabetics on Level 1 of the DQD. No significantly non-linear shape was observed for all three indicators. Our findings indicated a significant inverse association between the long-term diet quality assessed by the DBI-16 and diabetes risks, providing evidence for the positive role of healthy diets in diabetes prevention in Asia.
On the waveforms of gravitationally lensed gravitational waves

Strong lensing by intervening galaxies can produce multiple images of gravitational waves from sources at cosmological distances. These images acquire additional phase-shifts as the over-focused wavefront passes through itself along the line of sight. Time domain waveforms of Type-II images (associated with saddle points of the time delay) exhibit a non-trivial distortion from the unlensed waveforms. This phenomenon is in addition to the usual frequency-independent magnification, and happens even in the geometric limit where the wavelength is much shorter than the deflector's gravitational length scale. Similarly, Type-III images preserve the original waveform's shape but exhibit a sign flip. We show that for non-precessing binaries undergoing circular inspiral and merger, these distortions are equivalent to rotating the line of sight about the normal to the orbital plane by $45^\circ$ (Type II) and $90^\circ$ (Type III). This effect will enable us to distinguish between the different topological types among a set of multiple images, and give us valuable insight into the lens model. Furthermore, we show that for eccentric binaries, the waveform of a Type-II image is distorted in a manner that is inequivalent to a change of the source's orbital parameters.
The effects of reddening correction on the interpretation of spectrophotometry of Burnham's nebula and H―H objects

L'analyse et l'interpretation des donnees spectrophotometriques sont presentees pour la nebuleuse de Burnham dans l'etendue 3200 A≤λ≤11000 A, l'aspect critique de l'interpretation residant dans la determination et l'application des corrections du rougissement interstellaire. On demontre qu'il est imperatif que la courbe d'extinction utilisee pour corriger le rougissement soit la meme que celle utilisee pour calculer l'exces de couleur E(B-V). Ainsi, si la courbe interstellaire moyenne est utilisee pour deriver E(B-V) et une autre courbe, telle θ Ori, pour corriger le rougissement, des erreurs peuvent resulter au niveau des comparaisons entre des regions separees de longueurs d'onde, telles les regions optiques et UV. Un re-examen des donnees optiques et UV pour HH 2 en utilisant la meme courbe θ Ori pour calculer E(B-V) et corriger le rougissement permet de resoudre l'ecart associe aux flux optiques et UV

Testing quintessence models with large-scale structure growth

We explore the possibility of putting constraints on quintessence models with large-scale structure observations. In particular we compute the linear and second order growth rate of the fluctuations in different flavors of quintessence scenarios. We show that effective models of quintessence (e.g. with a constant equation of state) do not account of the results found in more realistic scenarios. The impact of these results on observational quantities such as the shape of the non-linear power spectrum in weak lensing surveys or the skewness of the convergence field are investigated. It appears that the observational signature of quintessence models are specific and rather large. They clearly cannot be mistaken with a change of (\\Omega_{0}).
A big-data analysis of the communication patterns of parliament members with the public on Facebook: top-down, non-inclusive and non-egalitarian

PurposeSocial media have become the main channel of direct communication between members of parliament and constituents. The study analyzes the content in all Israeli MPs' Facebook channels throughout an entire term of parliament and asks if the results are consistent with the equalization or the normalization hypotheses.Design/methodology/approachThe study uses automatic analysis to produce a birds-eye-view of the content uploaded to the Facebook pages of all Israeli MPs during a full term of parliament. All 106 MP pages were automatically scraped. Some complementary information was added to each post in the dataset, such as post length (number of words) and whether the page belongs to a member of the opposition or coalition. The total of 441,974 posts was analyzed to compare engagement and publication rates between pages, coalition vs opposition MPs, MPs vs users etc.FindingsThe findings demonstrate that the MP-Facebook sphere is non-egalitarian, in that it follows skewed distributions by MPs in terms of post publication and engagement rates; non-inclusive, in that pages of coalition members receive significantly much more engagement vis-a-vis pages of members of the oppositions; and “top-down”, in that MP-authored posts receive dramatically more engagement then user-authored posts, suggesting MPs have a near-monopoly on setting the agendas manifest in their pages, while users have extremely limited agenda-setting capabilities in these pages.Originality/valuePrevious studies have looked at the character of the interactions between MPs and constituents on the Internet and particularly on online social media. Yet, to the best of the authors’ knowledge, no study provides a birds-eye-view of the content in all MPs' Facebook channels throughout a full term of parliament. Such an analysis provides a more comprehensive understanding of the character and dynamics of conversations that take place in such arenas.
Dark matter stripping in galaxy clusters: a look at the stellar-to-halo mass relation in the Illustris simulation

Satellite galaxies in clusters represent a significant fraction of the global galaxy population, and because of the unusual dense environment they live in, their evolution is driven by mechanisms that are different from the ones affecting field or central galaxies. Understanding the different interactions they are subject to, and how they affect them, is therefore an important step towards explaining the global picture of galaxy evolution. In this paper, we use the high resolution hydrodynamical simulation Illustris-1 to study the satellite galaxies in the three most massive host haloes, corresponding to masses $M_{200} > 10^{14}\,h^{-1}M_{\odot}$. We measure the stellar-to-halo mass relation for the galaxies, and find that it is shifted towards lower halo masses compared to the relation for central galaxies. To explain this shift, we follow the satellite galaxies since their time of accretion in the clusters, and quantify the impact of dark matter stripping and star formation. We find that subhaloes start losing their dark matter as soon as they reach $\sim 1.5\times R_{\rm{vir}}$ from the centre of their host, and that up to 80\% of their dark matter content get stripped during infall. On the other hand, star formation quenching appears to be delayed and the galaxies continue to form stars for a few Gyr after being accreted into their host. The combination of these two effects makes the ratio of stellar mass to dark matter mass to vary drastically during infall, going from 0.03 to 0.3.
HI 21 cm absorption in low z damped Lyman- α systems

We report Giant Metrewave Radio Telescope (GMRT) 21 cm observations of two conﬁrmed and one candidate low redshift damped Lyman- α systems (DLAS). HI absorption was detected in the two conﬁrmed systems, at z = 0 . 2378 and z = 0 . 5247, with spin temperatures of 2050 ± 200 K and 330 ± 70 K respectively. The non-detection of absorption in the third (candidate) system places an upper limit on its optical depth, which in turn implies a 3 σ lower limit of 850 K on its spin temperature. Ground based K-band imaging observations (Turnshek et al. 2000) have identiﬁed the low T s absorber with a spiral galaxy while the high T s system appears to be an LSB galaxy. This continues the trend noted earlier by Chengalur & Kanekar (2000) of low spin temperatures for DLAS associated with spiral galaxies and high spin temperatures for those with no such association. Combining these new results with 21 cm observations from the published literature, we ﬁnd that (1) The 21 cm equivalent width ( EW 21 ) of DLAS increases with increasing N HI . Further, absorbers associated with spiral galaxies have systematically higher EW 21 at the same N HI than DLAS with no such association, (2) DLAS at high redshift ( z > ∼ 2) have small velocity spreads ∆ V , while, at low redshift ( z < ∼ 2), both large and small ∆ V are observed. These trends are in qualitative agreement with hierarchical models of galaxy formation.
Comparison of stellar population model predictions using optical and infrared spectroscopy

We present Gemini/GNIRS cross-dispersed near-infrared spectra of 12 nearby early-type galaxies, with the aim of testing commonly used stellar population synthesis models. We select a subset of galaxies from the atlas/ sample which span a wide range of ages (SSP-equivalent ages of 1--15~Gyr) at approximately solar metallicity. We derive star formation histories using four different stellar population synthesis models, namely those of [bruzual_stellar_2003], Conroy, Gunn \& White (2009; 2010), [maraston_stellar_2011] and [vazdekis_uv-extended_2016]. We compare star formation histories derived from near-infrared spectra with those derived from optical spectra using the same models. We find that while all models agree in the optical, the derived star formation histories vary dramatically from model to model in the near-infrared. We find that this variation is largely driven by the choice of stellar spectral library, such that models including high quality spectral libraries provide the best fits to the data, and are the most self-consistent when comparing optically-derived properties with near-infrared ones. We also find the impact of age variation in the near-infrared to be subtle, and largely encoded in the shape of the continuum, meaning that the common approach of removing continuum information with a high-order polynomial greatly reduces our ability to constrain ages in the near-infrared.
BROADBAND ELECTROSTATIC TRANSDUCERS : MODELING AND EXPERIMENTS

A model for broadband electrostatic transducers capable of generating and detecting ultrasound in air at megahertz frequencies has been developed. This model uses a lumped parameter approximation to describe a transducer with a grooved backplate and a stretched diaphragm. The mechanical stiffness effects included in the model are compressibility of the air gap separating the diaphragm and the backplate, flexure bending stiffness of the diaphragm, and in‐plane tension forces applied to the diaphragm. A prototype transducer with backplate grooves 200 μm wide and 3.75 μm deep was constructed using micromachining techniques. Measurements of the electrical admittance and transmit sensitivity were made at various polarization voltages and diaphragm tensions. Model predictions of transducer electrical admittance and transmit sensitivity compare well with experimental data. The resonance frequency is predicted within 50 kHz of the nominal measured value near 500 kHz, and model predictions of transmit sensitivity .
Reduction of test data volume and test application time by scan chain disabling technique

This article presents a method for test data compression aiming at simultaneously reducing test data volume and test application time for the scan sequential circuits. Compatible columns in the test set are repeatedly merged such that test data in the corresponding scan cells can be shared. To decode the compressed test data, a scan chain disabling technique is employed. Experimental results for the large ISCAS’89 benchmarks have demonstrated that significant reductions in both test data volume and test application time can be achieved.
