description: We refer the appearance of three-dimensional (3D) multiheaded chimera states that display cascades of self-organized spatiotemporal patterns of coexisting coherence and incoherence. We demonstrate that number of the incoherent chimera's domains can grow additively under appropriate varying the system parameters generating thereby head-adding cascades of the scroll wave chimeras. The phenomenon is derived for Kuramoto model of N identical phase oscillators placed in the 3D cube with periodic boundary conditions, parameters are coupling radius $r$ and phase lag $α$. To obtain the multiheaded chimeras, we perform the so-called 'cloning procedure' as follows: choose a sample single-headed 3D chimera state, make appropriate scale transformation, and put some number of copies of them into the unit cube. After, start numerical simulations with slightly perturbed initial conditions for long enough time to confirms or denies the state existence and stability. It is found, by this a way, that multiple scroll wave chimeras including those with incoherent rolls, Hopf links and trefoils admit this sort of multiheaded regeneration. On the other hand, multiple 3D chimeras without spiral rotations, like coherent and incoherent balls, tubes, crosses, and layers appear to be unstable under are destroyed rather fast even with any small perturbations.

description: We consider exploration algorithms of the random sequential adsorption type both for homogeneous random graphs and random geometric graphs based on spatial Poisson processes. At each step, a vertex of the graph becomes active and its neighboring nodes become explored. Given an initial number of vertices $N$ growing to infinity, we study statistical properties of the proportion of explored nodes in time using scaling limits. We obtain exact limits for homogeneous graphs and prove an explicit central limit theorem for the final proportion of active nodes, known as the \emph{jamming constant}, through a diffusion approximation for the exploration process. We then focus on bounding the trajectories of such exploration processes on random geometric graphs, i.e. random sequential adsorption. As opposed to homogeneous random graphs, these do not allow for a reduction in dimensionality. Instead we build on a fundamental relationship between the number of explored nodes and the discovered volume in the spatial process, and obtain generic bounds: bounds that are independent of the dimension of space and the detailed shape of the volume associated to the discovered node. Lastly, we give two trajectorial interpretations of our bounds by constructing two coupled processes that have the same fluid limits.

description: Due to the existence of diverse floral resources and favorable ecological conditions, Ethiopia is still one of the top ten natural honey producers worldwide. The study was conducted to identify and characterize the phenology and pollen potential of major bee forages in the various Agro-ecological conditions of Jimma zone. A total of 90 beekeepers were purposefully selected from three districts and interviewed using semi-structured questionnaire. The density and abundance of flowering plants were determined using sixty main quadrant sampling techniques. In addition, sixty-six pollen specimens were collected for one year using pollen traps at seven-day intervals and were also traced back to plant species level under a light microscope. The diversity of the bee flora was determined using the Shannon-Wiener diversity index. Based on survey, pollen load collection, and plant inventory data, the study has revealed the presence of 141 pollen and/or nectar-source honeybee plant species belonging to 62 families in the study area. Herbs were the most dominant bee flora growth forms, accounting for 62 (44%) of a total of 141 honeybee plant species, followed by trees at 48 (34%) and shrubs at 31 (22%), respectively. Herbaceous plant had a greater density value of plant species per plot than did trees and shrubs. The families with the highest number of species were Fabaceae 18 (12.8%), Asteraceae 11(7.8%), Poaceae 9(6.4%), Solanaceae 6 (4.3%), Acanthaceae 4 (2.8%), and Euphorbiaceae 4 (2.8%) in the study area. One hundred fifteen (81.6%) bee forage species were both sources of pollen and nectar, whereas fifteen (10.6%) were pollen sources and the remaining eleven (7.8%) were nectar source plant species. The Shannon diversity index and evenness were found to be 2.8 and 0.6, respectively. This indicated that the study area has a rich bee floral plant species and is suitable for beekeeping. The midland Agro-ecology relatively has the highest species diversity, richness and evenness compared to the highland and lowland Agro-ecologies. Two main flowering periods of honeybee plants were followed by two honey flow season. Therefore, beekeepers should follow floral calendar of honeybee plants to exploit the potential of the area for honey production.

description: Intersystem crossing is a radiationless process that can take place in a molecule irradiated by UV-Vis light, thereby playing an important role in many environmental, biological and technological processes. This paper reviews different methods to describe intersystem crossing dynamics, paying attention to semiclassical trajectory theories, which are especially interesting because they can be applied to large systems with many degrees of freedom. In particular, a general trajectory surface hopping methodology recently developed by the authors, which is able to include non-adiabatic and spin-orbit couplings in excited-state dynamics simulations, is explained in detail. This method, termed SHARC, can in principle include any arbitrary coupling, what makes it generally applicable to photophysical and photochemical problems, also those including explicit laser fields. A step-by-step derivation of the main equations of motion employed in surface hopping based on the fewest-switches method of Tully, adapted for the inclusion of spin-orbit interactions, is provided. Special emphasis is put on describing the different possible choices of the electronic bases in which spin-orbit can be included in surface hopping, highlighting the advantages and inconsistencies of the different approaches.

description: Freezing injury is a major environmental limiting factor affecting plant yield and geographical distribution. Little is known about the regulation of phenylpropanoid metabolism during freezing (FT) and post-freezing recovery (FR). Dendrobium ofﬁcinale is a valuable medicinal plant and hypersensitive to low temperature, especially freezing in winter. Here, we used metabolomics and transcriptomics analyses to reveal the regulation of of phenylpropanoid metabolism during FT and FR in D. ofﬁcinale. Most anthocyanin and flavonol signiﬁcantly increased during FR, including quercetin 3-O-glucoside (Q3G) and cyanidin 3-O-sophoroside (C3S) increased 104.6-fold and 66.8-fold in FR vs. CK. Transcriptomics analyses revealed the expression levels of flavonoid 3′- hydroxylase (F3`H) and ﬂavonol synthase (FLS), which were related to an increase in quercetin derivatives. Six phytohormone-related GO terms were enriched during FT and FR. Four genes were significantly affected by FT and FR, including MYB97, MYB39, fructosyltransferase, and zinc finger transcript factor. Four GA response-related genes, 2-oxoglutarate-dependent dioxygenases, were specially induced during freezing stress. Moreover, jasmonic acid (JA) and salicylic acid (SA) were significantly increased during FT, and only SA decreased during FR. This study provided understanding of phenylpropanoid metabolism under freezing stress and will be useful for enhancing freezing tolerance via molecular breeding in D. officinale.

description: Peanut (Arachis hypogaea L.) harbors a plethora of flavonoids that impart its health-promoting properties. To understand its biosynthesis and accumulation, a comparative expression analysis of flavonoid biosynthetic genes encoding enzymes responsible for synthesizing the main structure of flavonoids has been conducted in two differentially performing peanut varieties (PG 1247 and Bari 2011) in response to photoperiod and water availability. Transcript profiling of flavonoid biosynthetic genes indicated time-dependent expression of genes except for AhFLS in selected varieties in response to photoperiod variation. Many genes depicted a low degree of variation within varieties and water-deficient treatments. However, AhANS showed the highest variation for stress duration and varieties. In conclusion, this study has characterized the role of flavonoid biosynthesis in peanuts in response to photoperiod and water availability. Moreover, correlation analysis unraveled the coordination among the expression of flavonoid biosynthetic genes.

description: Most of the protein source feedstuffs for poultry like soybean and soybean meal are expensive. Thus alternative and cheaper non-conventional feedstuffs should be assessed in order to broaden sources of ingredients. Jatropha curcas seed meal is one of the non-conventional feed ingredients that can be used for poultry feed. Therefore, the objectives of this study were to investigate the effect of dietary inclusion of treated and untreated Jatropha seed meal on feed intake, feed conversion ratio, egg production and egg quality traits. A feeding trial was carried out for eight weeks at Hawassa University, with 250 Lohmann Brown commercial layers (42 weeks old). Chicken were allotted to five treatment diets replicated five times with 10 hens per replication in a completely randomized design. The control treatment (T1) represents the standard poultry feed that contained 42% white maize, 15% wheat bran, 7% noug cake, 25% soybean, 4% bone and meat meal, 4% limestone, 2.5% Premix and 0.5% salt. In the treatments T2 to T5, 5% of soybean seed in T1 was replaced by 1.25% untreated and treated Jatropha seed meal where T2, T3, T4 and T5 contained untreated, heat-treated, NaOH-treated and T5 yeast treated Jatropha seed meal, respectively. There were significant variations in daily feed intake, food conversion rate, hen-day egg production, hen-housed egg production and mortality among treatment groups. Chicken receiving T2 had reduced daily feed intake compared to hens that were fed on all other diets (p<0.05). Chickens reared under T1 had lower values of food conversion rate and mortality than chickens kept on all other diets (p<0.05). There was no significant differences among all treatment groups in egg shape index, egg weight and shell thickness. Substituting 5% soybean with untreated jatropha seed meal influences most of the tested parameters in the present study. On the other hand, the replacement of 5% quantity of soybean with treated jatropha seed meal had no effects on hen-daily egg production, hen-house egg production, Egg shape index, Egg weight, Shell thickness, Albumin height, Yolk height, Yolk weight and Haugh Unit compared to the standard poultry diet (T1). Accordingly, 1.25% heat, NaOH and yeast-treated jatropha seed meal could be used to replace 5% of the soybean seed in the Lohmann Brown layers diet.

description: Measurements and sensing implementations impose certain cost in sensor networks. The sensor selection cost optimization is the problem of minimizing the sensing cost of monitoring a physical (or cyber- physical) system. Consider a given set of sensors tracking states of a dynamical system for estimation purposes. For each sensor assume different costs to measure different (realizable) states. The idea is to assign sensors to measure states such that the global cost is minimized. The number and selection of sensor measurements need to ensure the observability to track the dynamic state of the system with bounded estimation error. The main question we address is how to select the state measurements to minimize the cost while satisfying the observability conditions. Relaxing the observability condition for structurally cyclic systems, the main contribution is to propose a graph theoretic approach to solve the problem in polynomial time. Note that, polynomial time algorithms are suitable for large-scale systems as their running time is upper-bounded by a polynomial expression in the size of input for the algorithm. We frame the problem as a linear sum assignment with solution complexity of O(m3).

description: We show why and how Compton wavelength and Schwarzschild radius should be combined into one single new length scale, which we call the Compton-Schwarzschild length. Doing so offers a resolution of the black hole information loss paradox, and suggests Planck mass remnant black holes as candidates for dark matter. It also compels us to introduce torsion, and identify the Dirac field with a complex torsion field. Dirac equation, and Einstein equations, are shown to be mutually dual limiting cases of an underlying gravitation theory which involves the Compton-Schwarzschild length scale, and includes a complex torsion field.

description: With the increasing human population, it is important to investigate the condition of Asejire Lake for sustainability. To this end, the effects of some weather factors were investigated on the fish assemblage, so as to provide necessary information to complement the dearth of reports about weather factors on the Lake. The study area was partitioned into three stations (upper, middle and lower) with fortnight collection of water samples, fish sampling and weather parameters for a period of 12 months (November 2017 – October 2018). Water samples were measured in situ using appropriate kits for pH, ammonia, nitrite and nitrates, dissolved oxygen and water temperature. Monofilament gill nets (40 mm and 60 mm) were used for fish sampling and were sorted and identified using appropriate monographs. The mean values across the sampling stations for temperature, pH, dissolved oxygen, ammonia, nitrates and nitrites were 18.36 ± 0.41oC, 7.30 ± 0.06, 2.37 ± 0.10 mg/L, 1.25 ± 0.05 mg/L, 1.34 ± 0.33 mg/L and 0.31 ± 0.03 mg/L, respectively. Across the months, mean values were 17.94 ± 0.48 oC, 2.67 ± 0.21 mg/L, 7.22 ± 0.21, 0.23 ± 0.02 mg/L, 0.13 ± 0.02 mg/L and 3.03 ± 0.03 for temperature, DO, pH, ammonia, nitrite and nitrates, respectively, with significant values (P < 0.05) among some parameters. A total of 1443 individual fishes (720 in the dry and 723 in the wet season) belonging to 27 species were encountered. March had the highest overall relative abundance of fish (23.77%) with Chrysichthys nigrodigitatus being the most abundant species (39.32%). March (47.64%) and April (32.78%) recorded the highest fish abundance in the dry and wet seasons respectively. Rainfall (540 mm) and temperature (35.50 °C) were highest in the month of September. The trend of rainfall and temperature was observed to increase over the months with t-values of 1.77 and 1.64 respectively. A negative relationship was observed between fish abundance with temperature (b1= -1.08) and rainfall (b1 = -0.26). It was observed that temperature values increased and rainfall values varied. Therefore, activities must be geared towards environmental management and consciousness of aquatic resources because of sustainability.

Non-Equilibrium Phase Transitions Induced by Social Temperature in Kinetic Exchange Opinion Models on Regular Lattices

description: In this work we study the critical behavior of a three-state opinion model in the presence of noise. This noise represents the independent behavior, that plays the role of social temperature. Each agent on a regular D-dimensional lattice has a probability $q$ to act as independent, i.e., he can choose his opinion independent of the opinions of his neighbors. Furthermore, with the complementary probability $1-q$ the agent interacts with a randomly chosen nearest neighbor through a kinetic exchange. Our numerical results suggest that the model undergoes nonequilibrium phase transitions at critical points $q_{c}$ that depend on the lattice dimension. These transitions are of order-disorder type, presenting the same critical exponents of the Ising model. The results also suggest that the upper critical dimension of the model is $D_{c}=4$, as for the Ising model. From the social point of view, with increasing number of social connections, it is easier to observe a majority opinion in the population.

description: The length-weight relationship of fish is an important fishery management tool. The objectives of the study were to determine the length-weight relationship, Fulton’s condition factor and the sex ratio of Lates niloticus in Lake Abaya. Total length (TL), total weight (TW), and sex data were collected from 755 fish samples (377 females and 378 males) for one year (January to December 2021) from the commercial fishery of Lake Abaya. The collected data were summarized by using descriptive statistics and analyzed with the application of Microsoft Excel 2010 and SPSS software. There was no significant deviation in sex ratio (M: F) from hypothetical 1:1 ratio (χ2 = 0.00; P > 0.05). The length-weight relationship was calculated using power function and obtained as TW = 0.0077*TL3.1176, (R2 = 0.8834), TW = 0.0078*TL3.1372, (R2 = 0.8548) and TW = 0.0098*TL3.0723, (R2 = 0.8713) for females, males and combined sexes, respectively. The regression coefficient “b” was significantly different from the cubic value “3” (P<0.05) and implied that L. niloticus of Lake Abaya follows a positive allometric growth pattern. The one-way ANOVA (P > 0.05) revealed that Fulton’s condition factor between sexes was insignificant but highly significant by month’s interaction (ANOVA, P < 0.05). The t-test also revealed a highly significant difference in a month’s interaction (t-test, P = 0.000) indicating the seasonal variation in the mean monthly condition factor. The average value of Fulton’s condition factor was higher than one and indicates that L. niloticus in Lake Abaya was in good health condition. The present study was focused only on L. niloticus and recommends that similar studies including feeding and reproductive biology should be conducted to determine the status of other fish species in Lake Abaya.

description: We discuss some problems related to induced subgraphs. The first problem is about getting a good upper bound for the chromatic number in terms of the clique number for graphs in which every induced cycle has length $3$ or $4$. The second problem is about the perfect chromatic number of a graph, which is the smallest number of perfect sets into which the vertex set of a graph can be partitioned. (A set of vertices is said to be perfect it it induces a perfect graph.) The third problem is on antichains in the induced subgraph ordering. The fourth problem is on graphs in which the difference between the chromatic number and the clique number is at most one for every induced subgraph of the graph. The fifth problem is on a weakening of the notorious Erdős-Hajnal conjecture. The last problem is on a conjecture of Gyárfás about $χ$-boundedness of a particular class of graphs.

description: We revisit the various approximations employed to study the long-term evolution of the magnetic field in neutron star cores and discuss their limitations and possible improvements. A recent controversy on the correct form of the induction equation and the relevant evolution timescale in superconducting neutron star cores is addressed and clarified. We show that this ambiguity in the estimation of timescales arises as a consequence of nominally large terms that appear in the induction equation, but which are, in fact, mostly irrotational. This subtlety leads to a discrepancy by many orders of magnitude when velocity fields are absent or ignored. Even when internal velocity fields are accounted for, only the solenoidal part of the electric field contributes to the induction equation, which can be substantially smaller than the irrotational part. We also argue that stationary velocity fields must be incorporated in the slow evolution of the magnetic field as the next level of approximation.

description: High-dose-rate brachytherapy is a tumor treatment method where a highly radioactive source is brought in close proximity to the tumor. In this paper we develop a simulated annealing algorithm to optimize the dwell times at preselected dwell positions to maximize tumor coverage under dose-volume constraints on the organs at risk. Compared to existing algorithms, our algorithm has advantages in terms of speed and objective value and does not require an expensive general purpose solver. Its success mainly depends on exploiting the efficiency of matrix multiplication and a careful selection of the neighboring states. In this paper we outline its details and make an in-depth comparison with existing methods using real patient data.

description: The requirement of high rate capability for operation at LHC, led 20 years ago to the achievement of Resistive Plate Chambers operated in avalanche mode, thanks to the introduction of new gas mixtures and to the development of the Front-End electronics. The need for a further increase of the rate capability, in view of the upgrades of LHC, is imposing new detector geometries with thinner gas gaps and electrodes. Streamer operation of RPCs may still be suitable for low rate experiments, and therefore in this paper a comparison between two different detector geometries, the old standard and the newly proposed one, is performed in streamer mode.

description: Watermarking techniques have been proposed during the last 10 years as an approach to trace network flows for intrusion detection purposes. These techniques aim to impress a hidden signature on a traffic flow. A central property of network flow watermarking is invisibility, i.e., the ability to go unidentified by an unauthorized third party. Although widely sought after, the development of an invisible watermark is a challenging task that has not yet been accomplished. In this paper we take a step forward in addressing the invisibility problem with DROPWAT, an active network flow watermarking technique developed for tracing Internet flows directed to the staging server that is the final destination in a data exfiltration attack, even in the presence of several intermediate stepping stones or an anonymous network. DROPWAT is a timing-based technique that indirectly modifies interpacket delays by exploiting network reaction to packet loss. We empirically demonstrate that the watermark embedded by means of DROPWAT is invisible to a third party observing the watermarked traffic. We also validate DROPWAT and analyze its performance in a controlled experimental framework involving the execution of a series of experiments on the Internet, using Web proxy servers as stepping stones executed on several instances in Amazon Web Services, as well as the TOR anonymous network in the place of the stepping stones. Our results show that the detection algorithm is able to identify an embedded watermark achieving over 95% accuracy while being invisible.

description: The discovery of a superconducting phase in sulfur hydride under high pressure with a critical temperature above 200 K has provided a new impetus to the search for even higher $T_c$. Theory predicted and experiment confirmed that the phase involved is H$_3$S with Im-3m crystal structure. The observation of a sharp drop in resistance to zero at $T_c$, its downward shift with magnetic field and a Meissner effect confirm superconductivity but the mechanism involved remains to be determined. Here, we provide a first optical spectroscopy study of this new superconductor. Experimental results for the optical reflectivity of H$_3$S, under high pressure of 150 GPa, for several temperatures and over the range 60 to 600 meV of photon energies, are compared with theoretical calculations based on Eliashberg theory using DFT results for the electron-phonon spectral density $α^2$F($Ω$). Two significant features stand out: some remarkably strong infrared active phonons at $\approx$ 160 meV and a band with a depressed reflectance in the superconducting state in the region from 450 meV to 600 meV. In this energy range, as predicted by theory, H$_3$S is found to become a better reflector with increasing temperature. This temperature evolution is traced to superconductivity originating from the electron-phonon interaction. The shape, magnitude, and energy dependence of this band at 150 K agrees with our calculations. This provides strong evidence of a conventional mechanism. However, the unusually strong optical phonon suggests a contribution of electronic degrees of freedom.

Electronic decoherence following photoionization: full quantum-dynamical treatment of the influence of nuclear motion

description: Photoionization using attosecond pulses can lead to the formation of coherent superpositions of the electronic states of the parent ion. However, ultrafast electron ejection triggers not only electronic but also nuclear dynamics---leading to electronic decoherence, which is typically neglected on time scales up to tens of femtoseconds. We propose a full quantum-dynamical treatment of nuclear motion in an adiabatic framework, where nuclear wavepackets move on adiabatic potential energy surfaces expanded up to second order at the Franck-Condon point. We show that electronic decoherence is caused by the interplay of a large number of nuclear degrees of freedom and by the relative topology of the potential energy surfaces. Application to $\mathrm{H_2O}$, paraxylene, and phenylalanine shows that an initially coherent state evolves to an electronically mixed state within just a few femtoseconds. In these examples the fast vibrations involving hydrogen atoms do not affect electronic coherence at short times. Conversely, vibrational modes involving the whole molecular skeleton, which are slow in the ground electronic state, quickly destroy it upon photoionization.

description: High-throughput sequencing of transfer RNAs (tRNA-Seq) is a powerful approach to characterize the cellular tRNA pool. Currently, however, analysing tRNA-Seq datasets requires strong bioinformatics and programming skills. tRNAstudio facilitates the analysis of tRNA-Seq datasets and extracts information on tRNA gene expression, post-transcriptional tRNA modification levels, and tRNA processing steps. Users need only running a few simple bash commands to activate a graphical user interface that allows the easy processing of tRNA-Seq datasets in local mode. Output files include extensive graphical representations and associated numerical tables, and an interactive html summary report to help interpret the data. We have validated tRNAstudio using datasets generated by different experimental methods and derived from human cell lines and tissues that present distinct patterns of tRNA expression, modification and processing.

description: We study the massless quark production in $SU(2)$ gauge chromoelectric field by single-time Wigner function covariantly with back reaction. The evolution of field and current are investigated. For a phenomenological distribution function, both the time and momentum dependence have been studied. Interesting phenomena are found, which are: when considering the back reaction, the yield of quark production is higher than the Bjorken expanding field, and momentum 'gap' with confinement phenomenon exists in the phenomenological distribution function. To have a better understanding on the phenomena, components of the Wigner function are qualitatively analyzed.

Scaling features of the tribology of polymer brushes of increasing grafting density around the mushroom to brush transition

description: Non equilibrium coarse grained, dissipative particle dynamics simulations of complex fluids, made up of polymer brushes tethered to planar surfaces immersed in a solvent yield non monotonic behavior of the friction coefficient as a function of the polymer grating density on the substrates, Γ, while the viscosity shows a monotonically increasing dependence on Γ. This effect is shown to be independent of the degree of polymerization, N, and the size of the system. It arises from the composition and the structure of the first particle layer adjacent to each surface that results from the confinement of the fluid. Whenever such layers are made up of as close a proportion of polymer beads to solvent particles as there are in the fluid, the friction coefficient shows a minimum, while for disparate proportions the friction coefficient grows. At the mushroom to brush transition (MBT) the viscosity scales with an exponent that depends on the characteristic exponent of the MBT (6/5) and the solvent quality exponent (ν= 0.5, for theta solvent), but it is independent of the polymerization degree (N). On the other hand, the friction coefficient at the MBT scales as μ~N^(6/5), while the grafting density at the MBT scales as Γ~ N^(-6/5) when friction is minimal, in agreement with previous scaling theories. We argue these aspects are the result of cooperative phenomena that have important implications for the understanding of biological brushes and the design of microfluidics devices, among other applications of current academic and industrial interest.
