Genetic Variability among Sugarcane Genotypes Based on TRAP Markers of Candidate Drought Genes and Some Agronomic Traits

: The study was focused on evaluation the performance of 12 sugarcane ( Saccharum officinarum L.) genotypes under drought stress. In addition, the genetic variability among the tested genotypes were studied using Target Region Amplification Polymorphism (TRAP). markers based on polymorphism in Aquaporin (Aqua) and Dehydration Binding Factor (DBF) candidate drought genes. Stalk length, diameter, number, volume and Brix% were sharply affected by drought stress in comparison to the control treatment, however, highly significant differences between the tested genotypes were observed. Drought tolerance index (D.T.I) indicated that EI 8-129 followed by EI 24-3 were the most tolerant genotypes, while NCO310 and G2000 -79 were the most drought sensitive. Drought stress decreased chlorophyll contents in most genotypes except in EI 264-2, G84 – 47 and EI 266-2 the chlorophyll was increased. The Aqua gene showed high number of amplified and polymorphic DNA fragments than DBF locus with 71.25% overall polymorphism. The largest number of amplified fragments was generated by Aqua + arbit.2 primer combination, and the lowest amplified with the DBF + arbit.1. The significant correlation between D.T. I. and number of amplified fragments from Aqua and DBF indicated that these loci play an important role in sugarcane drought tolerance. The lowest genetic similarity observed between the drought tolerant and the most sensitive genotypes illustrating that crosses between these genotypes would probably result in the highest variability for drought among the genotypes sampled. Cluster analysis based on TRAP markers of Aqua and DBF loci displayed that some genotypes that have common parents were grouped together and those displayed drought tolerance were also grouped together. The results reflected the feasibility and effectiveness of Aqua and DBF loci as molecular markers for drought tolerance in sugarcane.
Time Evolution of 3D Disk Formation with Misaligned Magnetic Field and Rotation Axes

Distinguishing diagnostic observational signatures produced by MHD models is essential in understanding the physics for the formation of protostellar disks in the Atacama Large Millimeter/submillimeter Array era. Developing suitable tools along with time evolution will facilitate better identification of diagnostic features. With the ray-tracing-based radiative transfer code Perspective we explore the time evolution of MHD models carried out in Li et al.—most of which have 90° misalignment between the rotational axis and the magnetic field. Four visible object types can be characterized, origins of which are dependent on the initial conditions. Our results show complex spiraling density, velocity, and polarization structures. The systems are under constant change, but many of those distinctive features are present already early on, and they grow more visible in time, but most could not be identified from the data without examining their change in time. The results suggest that spiraling pseudo-disk structures could function as an effective observation signature of the formation process, and we witness accretion in the disk with eccentric orbits that appear as spiral-like perturbation from simple circular Keplerian orbits. Magnetically aligned polarization appears purely azimuthal in the disk, and the magnetic field can lead to precession of the disk.
Nasoseptal Flap Versus Middle Turbinate Flap in Skull Base Reconstruction

Background: The expanded endonasal approaches to the skull base are modular approaches that arise from the sphenoidal sinus. The reconstructive techniques in these approaches are key to avoid postoperative complications. Available flaps for reconstruction include the pedicled nasoseptal flap, the trans- pterygoid temporoparietal fascia flap, and the posterior pedicle inferior turbinate flap (PPITF), among others. Recently, the middle turbinate flap and nasoseptal flap have been described in a cadaveric study. Objective: The aim of the current study was to compare results of using nasoseptal versus middle turbinate flaps in skull base reconstruction. Patients and methods: This interventional cohort study was carried out on 24 patients in Department of Otorhinolaryngology, Head and Neck Surgery, Zagazig University Hospitals. All patients with CSF leaks of variable reasons (congenital, traumatic, spontaneous) who required surgical repair with either vascularized nasoseptal mucosal flap or vascularized middle turbinate mucosal flap and fit for general anesthesia were included in the study. Results: Incidence rate of operation failure that was temporary (8.3%) in NSF group while in MTF the success rate was 100%. Conclusions : There are no significant differences in results of using nasoseptal versus middle turbinate flaps in skull base reconstruction.
Fast Octree Neighborhood Search for SPH Simulations

We present a new octree-based neighborhood search method for SPH simulation. A speedup of up to 1.9x is observed in comparison to state-of-the-art methods which rely on uniform grids. While our method focuses on maximizing performance in fixed-radius SPH simulations, we show that it can also be used in scenarios where the particle support radius is not constant thanks to the adaptive nature of the octree acceleration structure. Neighborhood search methods typically consist of an acceleration structure that prunes the space of possible particle neighbor pairs, followed by direct distance comparisons between the remaining particle pairs. Previous works have focused on minimizing the number of comparisons. However, in an effort to minimize the actual computation time, we find that distance comparisons exhibit very high throughput on modern CPUs. By permitting more comparisons than strictly necessary, the time spent on preparing and searching the acceleration structure can be reduced, yielding a net positive speedup. The choice of an octree acceleration structure, instead of the uniform grid typically used in fixed-radius methods, ensures balanced computational tasks. This benefits both parallelism and provides consistently high computational intensity for the distance comparisons. We present a detailed account of high-level considerations that, together with low-level decisions, enable high throughput for performance-critical parts of the algorithm. Finally, we demonstrate the high performance of our algorithm on a number of large-scale fixed-radius SPH benchmarks and show in experiments with a support radius ratio up to 3 that our method is also effective in multi-resolution SPH simulations.
Determination of the Maturity Stage and Most Proper Age for Harvesting the Fruit of Cherry Tomato (Solanum lycopersicum var. cerasiforme)

This study was carried out on the hybrid F 1 "Katalina 522" which belongs to cherry tomato (Solanum lycopersicum var. cerasiforme ) during the two seasons of 2018-2019 and 2019-2020 at a farm located in Zawyet Razeen village, Menoufia Governorate. The first step began with the labeling of flowers on the clusters starting at the full bloom to have nine fruit ages, namely 5, 10, 15, 20, 25, 30, 35, 40 and 45 days which were used to study the changes that occurred in the fruit physical and chemical characteristics in the collected developmental stages during cold storage to determine the maturity stage and the most suitable age for harvesting. The exerted figures showed that there was a rapid increase in the initial periods of the fruit fresh weight, size and diameter until the age of 20 days which was followed by a slow increase up to the age of 45 days, exhibiting statistically a curvilinear shape meanwhile the fruit firmness increased steadily till the age of 20 days after which a steady stable decline occurred till the last tested age of 45 days establishing in statistics a parabola shape. Moreover, the resulted data revealed a continuous quick gradual increase in T.S. S. and dry weight contents with the progress of age from the start of fruit formation up to the last examined age of 45 days that draw statistically a linear curve. However, the accumulation in the contents of ascorbic acid, lycopene and total sugars were increased gradually up to the age of 30 days, then followed by rapid increments up to the last age showing statistically a curvilinear shape. From another point of view, the characteristic of the pH reflects a gradual slow decrease with the progress of fruit age up to the age of 25 days followed by a steady gradual increase till the last age of 45 days. Storing these fruit developmental stages at 10ºC and 95% RH showed that the age of 35 days reflected the minimum loss in weight and the smallest unmarketable percentage during storage and at the same time contained the highest contents of T.S. S, ascorbic acid, lycopene, total sugars and dry weight. So, it is easy to show that the fruit maturity stage was attained at the age of 35 days, and the proper suitable age for harvesting was reached after 40 days.
A Semi-Markov Process Model for Performance Evaluation of DSRC Vehicular Safety Communication

In this study, a new semi-Markov process (SMP)-based model is devised to evaluate the IEEE 802.11p enhanced distributed channel access (EDCA) broadcast performance for vehicular safety communication. Differing from the existing SMP analytical models, the proposed model takes the virtual collision among various prioritized access categories (ACs) inside each vehicle into consideration. Moreover, in contrast to the Markov chain-based models, our model is simpler but with approximate accuracy. Concretely, we first capture the behavior of each AC’s backoff entity using SMP. Then, the parameters of interest in the vehicular ad hoc network (VANET) such as packet transmission probability, conditional collision probability, and saturation throughput are derived. Finally, via MATLAB simulations, we demonstrate that the newly developed model achieves comparable accuracy in calculating these output parameters while its complexity and computation time is around one-tenth of that of the Markov chain-based models. Therefore, the proposed model is more suitable for real-time performance analysis of IEEE 802.11p EDCA safety communication in a freeway scenario.
Improving Learning Quality Through Infrastructure Management

: The purpose of this research is to analyze and explain the design, organization, execution, and oversight of infrastructure facilities in order to improve the quality of learning at SMP Negeri 01 Belitang II. This study employs a qualitative approach. Data analysis employs analysis, namely data reduction, data display, and conclusion making. The study's findings were examined through four components of infrastructure management implementation: planning, organizing, implementing, and supervising in order to improve the quality of learning at SMP Negeri 01 Belitang II. The infrastructure design step involves developing many programs and carefully preparing so that students may have pleasant amenities while not incurring high school costs. The organizational stage begins with the selection of those who will carry out the responsibilities or job of task division, including the principal, vice principal, teachers, and TU personnel. The principal determines the procedure of implementing infrastructure with the cooperation of the treasurer, and the deputy head of the facility supplies any items as needed. The infrastructure facilities are then supervised to ensure that their usage and maintenance function smoothly and do not interfere with the continuous learning process.
Developing a shared supplier with endogenous spillovers

Firms who buy from suppliers often engage in supplier development to reduce the supplier's production cost. Being aware that their efforts may benefit a rival firm when there is a shared supplier, some buyers only invest in “specific supplier development,” that is, in those processes or technologies where spillover cannot occur. Other buyers willingly accept the spillover that arises from supplier development, and invest in “generic supplier development. ” Our game‐theoretic model captures a buyer's choice to invest in these distinct supplier development types as a way to endogenize spillovers. In contrast to the literature, this paper considers the benefits of investing in a combination (i.e., portfolio) of cost‐reducing generic and specific supplier development. We demonstrate how supplier development affects a shared supplier's wholesale pricing decisions; whereas generic supplier development lowers wholesale prices equally across buyers, specific supplier development only lowers the wholesale price of the investing party. Our model shows that buyers should treat the spillovers from generic supplier development as an investment opportunity rather than a threat. In equilibrium, a buyer will always invest in a portfolio of both supplier development types, and having a better generic than specific investment capability may even make generic supplier development the most prevalent option for him, depending on the level of competition. Moreover, even if the buyers can commit to only investing in specific supplier investment, the resulting equilibrium gives lower buyer profits than a portfolio that includes generic investments. We also find that the presence of specific investments may raise generic supplier development, benefiting all supply chain actors. However, incorporating specific supplier development into a supplier development portfolio or a commitment to investment in only specific supplier development can lead to a prisoner's dilemma in terms of buyer profits. We show how investment capabilities and competitive intensity drive the buyers' investment decisions and supply chain actors' profits. The paper's main results also hold for asymmetric generic investment capabilities, though we highlight that the least capable buyer will free‐ride on his rival's investments, consequently making him earn higher profits.
Limits on Dust in Rich Clusters of Galaxies from the Color of Background Quasars

I measure the V - I color distribution of two samples of radio-selected quasars. Quasars from one sample are projected on the sky within 1° of a rich foreground Abell cluster of galaxies, while quasars from the other sample are more than 3° from any such cluster. There is no significant difference between the color distribution of the two samples. The 90% upper limit on the relative reddening between the two samples is E(B - V) = 0.05 mag. This result limits the allowed quantity of smoothly distributed dust in rich clusters and contradicts previous indications of the existence of such a component.
Revisiting the science case for near-UV spectroscopy with the VLT

In the era of Extremely Large Telescopes, the current generation of 8-10m facilities are likely to remain competitive at far-blue visible wavelengths for the foreseeable future. High-efficiency (<20%) observations of the ground UV (300- 400 nm) at medium resolving power (R~20,000) are required to address a number of exciting topics in stellar astrophysics, while also providing new insights in extragalactic science. Anticipating strong demand to better exploit this diagnostic-rich wavelength region, we revisit the science case and instrument requirements previously assembled for the CUBES concept for the Very Large Telescope.
A Neutral Hydrogen Survey of Polar-Ring Galaxies: I. Green Bank Observations of the Northern Sample

We present the results of a neutral hydrogen survey conducted with the Green Bank 140-foot radio telescope of 47 northern objects in the polar-ring galaxy atlas of Whitmore \etal\ (1990). We detected 39 of these above our detection limit of 1.7 \hbox{Jy\CDOT\KMS}; the average measured flux of 21 Jy\CDOT\KMS\ corresponds to an average neutral hydrogen mass of $\rm 5.3 \times 10^9$ \MSUN for a Hubble constant of $\rm H_0 = 75$ \KMS \ Mpc$^{-1}$. For the polar-ring galaxies in our sample that have also been observed with radio arrays, we find that the 21\AMIN\ (FWHM) Green Bank beam often includes much more flux than found by the synthesis instruments for the polar rings alone; some of these galaxies are known to have gas-rich companions. We compare the neutral hydrogen content of the sample to the blue luminosity and IRAS fluxes. The \HI-to-blue- light ratios of the confirmed and probable polar rings are around unity in solar units, indicating that polar ring galaxies (or their environments) are as gas-rich as typical irregular galaxies. For their blue luminosity, the confirmed polar rings are underluminous in the far-infrared, as compared with the rest of the sample. They are also FIR-underluminous for their \HI\ masses, which suggests that most of the gas in the ring may be in stable orbits, rather than flowing inward to trigger star formation in the central galaxy. The more disordered class of `related objects,' which includes a number of obvious mergers, is highly luminous in the far-infrared.
Extended scattering continua characteristic of spin fractionalization in the two-dimensional frustrated quantum magnet Cs 2 CuCl 4 observed by neutron scattering

The magnetic excitations of the quasi-2D spin-1/2 frustrated Heisenberg antiferromagnet ${\mathrm{Cs}}_{2}{\mathrm{CuCl}}_{4}$ are explored throughout the 2D Brillouin zone using high-resolution time-of-flight inelastic neutron scattering. Measurements are made both in the magnetically ordered phase, stabilized at low temperatures by the weak interlayer couplings, as well as in the spin liquid phase above the ordering temperature ${T}_{N},$ when the 2D magnetic layers are decoupled. In the spin liquid phase the dynamical correlations are dominated by highly dispersive excitation continua, a characteristic signature of fractionalization of $S=1$ spin waves into pairs of deconfined $S=1/2$ spinons and the hallmark of a resonating-valence-bond (RVB) state. The boundaries of the excitation continua have strong 2D-modulated incommensurate dispersion relations. Upon cooling below ${T}_{N}$ magnetic order in an incommensurate spiral forms due to the 2D frustrated couplings. In this phase sharp magnons carrying a small part of the total scattering weight are observed at low energies, but the dominant continuum scattering which occurs at medium to high energies is essentially unchanged compared to the spin liquid phase. Linear spin-wave theory including one- and two-magnon processes can describe the sharp magnon excitation, but not the dominant continuum scattering, which instead is well described by a parametrized two-spinon cross section. Those results suggest a crossover in the nature of the excitations from $S=1$ spin waves at low energies to deconfined $S=1/2$ spinons at medium to high energies, which could be understood if ${\mathrm{Cs}}_{2}{\mathrm{CuCl}}_{4}$ was in the close proximity of transition between a fractional RVB spin liquid and a magnetically ordered state. A large renormalization factor of the excitation energies $[R=1.63(5)],$ indicating strong quantum fluctuations in the ground state, is obtained using the exchange couplings determined from saturation-field measurements. We provide an independent consistency check of this quantum renormalization factor using measurements of the second moment of the paramagnetic scattering.
Tunable tunneling: An application of stationary states of Bose-Einstein condensates in traps of finite depth

The fundamental question of how Bose-Einstein condensates tunnel into a barrier is addressed. The cubic nonlinear Schrodinger equation with a finite square well potential, which models a Bose-Einstein condensate in a quasi-one-dimensional trap of finite depth, is solved for the complete set of localized and partially localized stationary states, which the former evolve into when the nonlinearity is increased. An immediate application of these different solution types is tunable tunneling. Magnetically tunable Feshbach resonances can change the scattering length of certain Bose-condensed atoms, such as $^{85}$Rb, by several orders of magnitude, including the sign, and thereby also change the mean field nonlinearity term of the equation and the tunneling of the wavefunction. We find both linear-type localized solutions and uniquely nonlinear partially localized solutions where the tails of the wavefunction become nonzero at infinity when the nonlinearity increases. The tunneling of the wavefunction into the non-classical regime and thus its localization therefore becomes an external experimentally controllable parameter.
Complex magnetic topology and strong differential rotation on the low-mass T Tauri star V2247 Oph

From observations collected with the ESPaDOnS spectropolarimeter at the Canada–France–Hawaii Telescope, we report the detection of Zeeman signatures on the low-mass classical T Tauri star (cTTS) V2247 Oph. Profile distortions and circular polarization signatures detected in photospheric lines can be interpreted as caused by cool spots and magnetic regions at the surface of the star. The large-scale field is of moderate strength and highly complex; moreover, both the spot distribution and the magnetic field show significant variability on a time-scale of only 1 week, as a likely result of strong differential rotation. Both properties make V2247 Oph very different from the (more massive) prototypical cTTS BP Tau; we speculate that this difference reflects the lower mass of V2247 Oph. During our observations, V2247 Oph was in a low-accretion state, with emission lines showing only weak levels of circular polarization; we nevertheless find that excess emission apparently concentrates in a mid-latitude region of a strong radial field, suggesting that it is the footpoint of an accretion funnel. The weaker and more complex field that we report on V2247 Oph may share similarities with those of very-low-mass late-M dwarfs and potentially explain why low-mass cTTSs rotate on average faster than intermediate-mass ones. These surprising results need confirmation from new independent data sets on V2247 Oph and other similar low-mass cTTSs.
Radon Measurement and Radiological Dose Assessment From Terrestrial Rocks Using Solid-State Nuclear Track Detectors

and LR-115 NTD are 11.27 and 11.29 kBqm -3 , respectively, indicating a consensual correlation that depends on the charged particles, particularly accumulation radon gas emissions from investigated samples measured by Nuclear Track Detectors. The findings revealed a significant quantity of NORM in the SGM due to the radon concentration which is greater than the IAEA, ICRP, and UNSCEAR recommended limit of 1000 Bqm -3 . The present study aims to evaluate and predict the radioactive changes in the investigation area, assess dangerous radiation, and implement radiation safety standards for the workers in the SGM. The current research may also be useful in the future investigation and mining of nuclear materials for optimization business in the SGM and its surrounding area.
