description: A new true Gaussian digital shaper of detector pulses is tested and compared to the standard trapezoidal shaper in terms of output count rate, amplitude resolution and biasing the output shaped pulses. The true Gaussian shaper allows for shaping detector pulses into a symmetrical form which width can be considerably less than their rise time. Standard trapezoidal shapers cannot provide such short pulses. Therefore, the dead time of the true Gaussian shaper can be considerably reduced in regards to that of trapezoidal shaper. The output count rate of the true Gaussian and trapezoidal pulses are compared in a wide range of input count rates. The maximal output count rate of the true Gaussian shaper has been found to exceed in several times the rate of the trapezoidal shapers. The true Gaussian shapers provide better resolution and biasing-free measurements of pulse amplitudes at high count rates. The tests have been performed by modeling output signals of silicon drift detector (SDD) VITUS H7 equipped with AXAS-D pre-amplifier developed by KETEK GmbH for measurements of soft X-ray spectra at high count rates.

description: We consider the XXZ spin chain in the scaling limit in the Matsubara direction. The main result of this paper is new representations for the functions $Ψ(l, κ)$ and $Θ(l, m; κ, α)$ associated with the function $ω(ζ, ξ; κ, κ)$ found in the expression for the correlation function of the generators of the fermionic basis for the XXZ spin chain. The final result incorporates the case of particle-hole excitations which is needed for the relation of the fermionic basis to the Virasoro basis of the CFT descendants.

description: Recent experiments strongly indicate deep connections between transports of strange metal and high $T_c$ superconductors. For instance, it is known that the dependence of the zero-temperature phase stiffness on the critical superconducting temperature becomes linear in underdoped materials. In this paper, we investigate relation meticulously between the phase stiffness and the critical superconducting temperature for the Gubser-Rocha holographic superconductor model in the probe limit. The superfluid density (or phase stiffness) can be extracted from the low-frequency dependence of the AC conductivity. More importantly, we find linear dependence of zero-temperature superfluid density on the critical superconducting temperature, which has a similarity to a recent experiment in a film cuprate. In addition, we also provide some approximate formulas for the critical temperatures and the AC conductivity.

Then we present a set of Stata programs that estimate the propensity score in a setting with a continuous treatment, test the balancing property of the generalized propensity score, and estimate the dose–response function. We illustrate these programs by using a dataset collected by Imbens, Rubin, and Sacerdote (2001, American Economic Review 91: 778–794).

description: Large language models (LLMs) are able to engage in natural-sounding conversations with humans, showcasing unprecedented capabilities for information retrieval and automated decision support. They have disrupted human-technology interaction and the way businesses operate. However, technologies based on generative artificial intelligence (GenAI) are known to hallucinate, misinform, and display biases introduced by the massive datasets on which they are trained. Existing research indicates that humans may unconsciously internalize these biases, which can persist even after they stop using the programs. This study explores the cultural self-perception of LLMs by prompting ChatGPT (OpenAI) and Bard (Google) with value questions derived from the GLOBE project. The findings reveal that their cultural self-perception is most closely aligned with the values of English-speaking countries and countries characterized by sustained economic competitiveness. Recognizing the cultural biases of LLMs and understanding how they work is crucial for all members of society because one does not want the black box of artificial intelligence to perpetuate bias in humans, who might, in turn, inadvertently create and train even more biased algorithms.

description: Forecasting consumer price index (CPI) inflation is of paramount importance for both academics and policymakers at the central banks. This study introduces a filtered ensemble wavelet neural network (FEWNet) to forecast CPI inflation, which is tested on BRIC countries. FEWNet breaks down inflation data into high and low-frequency components using wavelets and utilizes them along with other economic factors (economic policy uncertainty and geopolitical risk) to produce forecasts. All the wavelet-transformed series and filtered exogenous variables are fed into downstream autoregressive neural networks to make the final ensemble forecast. Theoretically, we show that FEWNet reduces the empirical risk compared to fully connected autoregressive neural networks. FEWNet is more accurate than other forecasting methods and can also estimate the uncertainty in its predictions due to its capacity to effectively capture non-linearities and long-range dependencies in the data through its adaptable architecture. This makes FEWNet a valuable tool for central banks to manage inflation.

Are there cosmological evolution trends on Gamma-Ray Burst features?

description: The variability of gamma-ray burst (GRB) is thought to be correlated with its absolute peak luminosity, and this relation had been used to derive an estimate of the redshifts of GRBs. Recently Amati et al. presented the results of spectral and energetic properties of several GRBs with known redshifts. Here we analyse the properties of two group GRBs, one group with known redshift from afterglow observation, and another group with redshift derived from the luminosity - variability relation. We study the redshift dependence of various GRBs features in their cosmological rest frames, including the burst duration, the isotropic luminosity and radiated energy, and the peak energy $E_p$ of $νF_ν$ spectra. We find that, for these two group GRBs, their properties are all redshift dependent, i.e. their intrinsic duration, luminosity, radiated energy and peak energy $E_p$, are all correlated with the redshift, which means that there are cosmological evolution effects on gamma-ray bursts features, and this can provide an interesting clue to the nature of GRBs. If this is true, then the results also imply that the redshift derived from the luminosity - variability relation may be reliable.

description: Much of the success of the produce industry relies on a carefully choreographed supply chain. Planting the perfect varieties, harvesting at the peak of ripeness, packing in customized cartons, transporting fresh produce thousands of miles, and merchandising, marketing and promoting it at just the right moment, is a feat that relies on careful and detailed communication and coordination between grower/shippers and produce retailers. The objective of this study is to document the status, challenges and changes within the fresh produce distribution system. The method guiding this study has three major components: (1) a review of the relevant trade and academic literature on the fresh produce industry, (2) an extensive mail questionnaire directed at produce retailers, and (3) focus groups with grower/shippers. The retail questionnaire was sent to 270 produce retail executives in April 2001. At each retail firm, senior-level produce executives were asked to complete a questionnaire by describing supply chain management practices within their organizations for 1996 and today, 2001. Furthermore, they were asked to projectwhat the practices will be 5 years into the future, in 2006. The survey generated 44 useable questionnaire responses, from a representative sample of supermarkets in terms both of geographical and size distribution. Respondents ranged from a number of singlestore operators to the very largest of multi-billiondollar retail operators. Such representativeness allows for a cautious generalization from the survey results to the produce industry as a whole.

description: Limnogonus (Limnogonus) profugus Drake & Harris, 1930
Geographical distribution: Brazil, Peru, Paraguay, and Argentina. There is one record from Venezuela, which is questionable and not considered here.
 Distribution in Brazil: Central-West and Southeast regions (MT, MG, MS, SP, RJ) (Drake & Harris 1930; Kuitert 1942; Nieser & Melo 1997; Vianna & Melo 2003; Souza et al. 2006; Ribeiro et al. 2010).
Comments: The type-locality mentioned by Drake and Harris (1930) is “Chapada, Brazil,” and no collector is cited. However, types of other species described by those authors from Chapada have been collected by Herbert Huntington Smith, who made collections on the surroundings of Chapada dos Guimarães between 1882 and 1886. At that time, the locality was known only as “Chapada,” and material observed by Drake and Harris was probably originated from Chapada dos Guimarães, MT.

description: Nonlinear transport in the low temperature vortex glass state of single crystal Bi_{2}Sr_{2}CaCu_{2}O_{8} has been investigated over long times (up to two weeks) with fast current pulses driven along the ab plane. It is found that at low temperature and high magnetic field both zero field cooled (ZFC) and field cooled (FC) samples relax towards the same equilibrium state, which is much closer to the original ZFC state than to the FC state. The implication of this FC metastability for the vortex phase diagram is discussed in the context of previous measurements.

description: The latest advances in the field of photonics have enabled the simulation of an increasing number of quantum models in photonic systems, turning them into an important tool for realizing exotic quantum phenomena. In this paper we suggest different ways in which these systems can be used to study the interplay between flat band dynamics, topology and interactions in a well-known quasi-1D topological insulator: the Creutz ladder. Firstly, a simple experimental protocol is proposed to observe the Aharonov-Bohm localization in the noninteracting system, and the different experimental setups that might be used for this are reviewed. We then consider the inclusion of a repulsive Hubbard-type interaction term, which can give rise to repulsively bound pairs termed doublons. The dynamics of these quasiparticles are studied for different points of the phase diagram, including a regime in which pairs are localized and particles are free to move. Finally, a scheme for the photonic implementation of a two-particle bosonic Creutz-Hubbard model is presented.

description: Spin effects in exclusive and inclusive reactions provide an essential new dimension for testing QCD and unraveling hadron structure. Remarkable new experiments from SLAC, HERMES (DESY), and the Jefferson Laboratory present many challenges to theory, including measurements at HERMES and SMC of the single spin asymmetries in pion electroproduction, where the proton is polarized normal to the scattering plane. This type of single spin asymmetry may be due to the effects of rescattering of the outgoing quark on the spectators of the target proton, an effect usually neglected in conventional QCD analyses. Many aspects of spin, such as single-spin asymmetries and baryon magnetic moments are sensitive to the dynamics of hadrons at the amplitude level, rather than probability distributions. I illustrate the novel features of spin dynamics for relativistic systems by examining the explicit form of the light-front wavefunctions for the two-particle Fock state of the electron in QED, thus connecting the Schwinger anomalous magnetic moment to the spin and orbital momentum carried by its Fock state constituents and providing a transparent basis for understanding the structure of relativistic composite systems and their matrix elements in hadronic physics. I also present a survey of outstanding spin puzzles in QCD, particularly the double transverse spin asymmetry A_{NN} in elastic proton-proton scattering, the J/psi to rho-pi puzzle, and J/psi polarization at the Tevatron.

description: O Brasil, ao longo de todo seu processo de formação econômica, mostrou vocação incontestável para a agricultura. Atualmente, o setor continua sendo de vital importância para a economia nacional, uma vez que permite ao país atrair divisas através das exportações e a geração de empregos nas áreas produtoras. Um importante setor que tem se destacado neste cenário é o complexo soja, composto pela soja em grão, farelo e óleo de soja. Dentro do complexo as exportações de soja em grão tem ganhado importância crescente. No período de 1986 a 2004 a produção nacional e as exportações cresceram 297,16% e 1.749% respectivamente. O país é um dos principais produtores mundiais juntamente com Estados Unidos e Argentina. O presente trabalho tem por objetivo analisar a posição competitiva do Brasil no mercado internacional de soja em grão. Para tanto, utilizou-se o modelo de Balassa, pelo qual é possível identificar se determinado país apresenta, ou não, Vantagem Comparativa Revelada – VCR na comercialização de certo produto em determinado mercado, e os de Lafay, que possibilitam identificar a Posição Relativa – POS e a Vantagem Comparativa Revelada – VCR (Lafay) do país no mercado internacional do produto em questão. A análise dos resultados mostrou que, apesar das deficiências de infra-estrutura e dos subsídios agrícolas dos países ricos, as exportações de soja em grão são altamente competitivas e que ainda há espaço para melhorar a posição competitiva do país com relação aos seus principais competidores.

description: This published paper investigates the distributed tracking control problem for a class of Euler-Lagrange multi-agent systems when the agents can only measure the positions. In this case, the lack of the separation principle and the strong nonlinearity in unmeasurable states pose severe technical challenges to global output-feedback control design. To overcome these difficulties, a global nonsingular coordinate transformation matrix in the upper triangular form is firstly proposed such that the nonlinear dynamic model can be partially linearized with respect to the unmeasurable states. And, a new type of velocity observers is designed to estimate the unmeasurable velocities for each system. Then, based on the outputs of the velocity observers, we propose distributed control laws that enable the coordinated tracking control system to achieve uniform global exponential stability (UGES). Both theoretical analysis and numerical simulations are presented to validate the effectiveness of the proposed control scheme. Followed by the original paper, a typo and a mistake is corrected.

description: The oxygen-deficient (double) perovskite YBaMn$_2$O$_5$, containing corner-linked MnO$_5$ square pyramids, is found to exhibit ferrimagnetic ordering in its ground state. In the present work we report generalized-gradient-corrected, relativistic first-principles full-potential density-functional calculations performed on YBaMn$_2$O$_5$ in the nonmagnetic, ferromagnetic and ferrimagnetic states. The charge, orbital and spin orderings are explained with site-, angular momentum- and orbital-projected density of states, charge-density plots, electronic structure and total energy studies. YBaMn$_2$O$_5$ is found to stabilize in a G-type ferrimagnetic state in accordance with experimental results. The experimentally observed insulating behavior appears only when we include ferrimagnetic ordering in our calculation. We observed significant optical anisotropy in this material originating from the combined effect of ferrimagnetic ordering and crystal field splitting. In order to gain knowledge about the presence of different valence states for Mn in YBaMn$_2$O$_5$ we have calculated $K$-edge x-ray absorption near-edge spectra for the Mn and O atoms. The presence of the different valence states for Mn is clearly established from the x-ray absorption near-edge spectra, hyperfine field parameters and the magnetic properties study. Among the experimentally proposed structures, the recently reported description based on $P$4/$nmm$ is found to represent the stable structure.

description: The provision of communication services via portable and mobile devices, such as aerial base stations, is a crucial concept to be realized in 5G/6G networks. Conventionally, IoT/edge devices need to transmit the data directly to the base station for training the model using machine learning techniques. The data transmission introduces privacy issues that might lead to security concerns and monetary losses. Recently, Federated learning was proposed to partially solve privacy issues via model-sharing with base station. However, the centralized nature of federated learning only allow the devices within the vicinity of base stations to share the trained models. Furthermore, the long-range communication compels the devices to increase transmission power, which raises the energy efficiency concerns. In this work, we propose distributed federated learning (DBFL) framework that overcomes the connectivity and energy efficiency issues for distant devices. The DBFL framework is compatible with mobile edge computing architecture that connects the devices in a distributed manner using clustering protocols. Experimental results show that the framework increases the classification performance by 7.4\% in comparison to conventional federated learning while reducing the energy consumption.

description: High temperature REBCO superconducting tapes are very promising for high-field magnets. Under high magnetic fields there are high electro-mechanical forces, and thus concern for mechanical damage. Due to large screening currents and composite structure of the tape, the mechanical design of these magnets are not straightforward. In addition, many present designs use insulated winding. In this work we develop a novel two-dimensional axisymmetric finite element tool programmed in MATLAB that assumes the displacement field within linear elastic range. The stack of pancakes and a large number of REBCO tape turns are approximated as an anisotropic bulk hollow cylinder. Our results agree with uni-axial stress experiments in literature, validating the bulk approximation. Here, we study the following configuration. The current is first ramp up to below the critical current and we calculate the screening currents and the forces that they cause using the MEMEP model. As a case study 32 T REBCO superconductor magnet is simulated numerically. We have done complete mechanical analysis of the magnet by including the axial and shear mechanical quantities for each pancake unlike previous work where only radial and circumferential quantities are focused. Effect on mechanical quantities without screening current is also calculated and compared. It is shown that including screening current induced field strongly affect the mechanical quantities, specially the shear stress. The latter might be the critical quantity for certain magnet configurations. Additionally, in order to overcome high stresses, a stiff over banding of different material is considered and numerically modelled which significantly reduces the mechanical stresses. The FE based model developed is efficient to calculate the mechanical behaviour of any general superconductor magnet and its devices.
Non-Markovian Models of Environmentally-driven Disentanglement in Molecular Charge Qubits

Publisher: name: arXiv
Year: 2019

description: Models of quantum disentanglement are developed for nanometer-scale molecular charge qubits (MCQs). Two MCQs, $A$ and $B$, are prepared in a Bell state and separated for negligible $A$-$B$ interactions. Interactions between the local environment and each MCQ unravels $A$-$B$ entanglement during coherent system+environment evolution. Three models are used for dynamics: (1) a previously-developed, numerical model, in which both $AB$ and environment $\mathcal{E}$ are modeled explicitly; (2) an exact, semi-analytic model, in which only the dynamics of $AB$ are calculated, and (3) an approximate model developed from the semi-analytic model and assumptions about randomness in $\mathcal{E}$. In the approximate model, the non-zero coherences of the density operator for $AB$ decay with a Gaussian time dependence. This provides a time scale for system dynamics in the exact models as well. This time scale is related directly to the strength of AB-$\mathcal{E}$ interaction. This time scale describes cases where environmental interaction with one target MCQ is dominant, generalizing a previous time scale applicable only when both MCQs have roughly the same strength of interaction with the local environment. Entanglement is measured using two-qubit correlation functions, the dynamics of which are used to demonstrate the effectiveness of the time scale. The early-time decay of coherences and the loss of entanglement is well-characterized as Gaussian, a behavior that Markovian models for memoryless environments cannot capture. The approximate Gaussian model may be used to describe the dynamics of MCQ disentanglement under the influence of environments modeled here, as well as other environments where randomness is present.

description: The artificial lateral line (ALL), comprising distributed flow sensors, has been successful in sensing motion states of bioinspired underwater robots like robotic fish. However, its application to robots driven by rotating propellers remains unexplored due to the complexity of propeller wake flow. This paper investigates the feasibility of using ALL to sense propeller wake for underwater robot leader-follower formation. To estimate the lateral motion states of a leader propeller, this paper designs a multi-output deep learning network that extracts temporal and spatial features from distributed pressure measurements of propeller wake. Extensive experiments are conducted on a designed testbed, the results of which validate the effectiveness of the proposed propeller wake sensing method.

description: Here we calculate the GRB afterglow light curves from a relativistic jet as seen by observers at a wide range of viewing angles from the jet axis, and the jet is uniform or non-uniform. We find that, for uniform jet the afterglow light curves for different viewing angles are somewhat different: in general, there are two breaks in the light curve, corresponding to the time $γ\sim (θ_j-θ_v)^{-1}$ and $γ\sim (θ_j+θ_v)^{-1}$ respectively. However, for non-uniform jet, the things become more complicated. For the case $θ_v=0$, we can obtain the analytical results, for $k<8/(p+4)$ there should be two breaks in the light curve correspond to $γ\simθ_c^{-1}$ and $γ\simθ_j^{-1}$ respectively, while for $k>8/(p+4)$ there should be only one break corresponds to $γ\simθ_c^{-1}$, and this provides a possible explanation for some rapidly fading afterglows whose light curves have no breaks since the time at which $γ\simθ_c^{-1}$ is much earlier than our first observation time. For the case $θ_v\neq 0$, our numerical results show that, the afterglow light curves are strongly affected by the values of $θ_v$, $θ_c$ and $k$. If the values of $θ_v/θ_c$ and $k$ are larger, there will be a prominent flattening in the afterglow light curve, which is quite different from the uniform jet, and after the flattening a very sharp break will be occurred at the time $γ\sim (θ_v + θ_c)^{-1}.

description: Collaborative Edge Computing (CEC) is a new edge computing paradigm that enables neighboring edge servers to share computational resources with each other. Although CEC can enhance the utilization of computational resources, it still suffers from resource waste. The primary reason is that end-users from the same area are likely to offload similar tasks to edge servers, thereby leading to duplicate computations. To improve system efficiency, the computation results of previously executed tasks can be cached and then reused by subsequent tasks. However, most existing computation reuse algorithms only consider one edge server, which significantly limits the effectiveness of computation reuse. To address this issue, this paper applies computation reuse in CEC networks to exploit the collaboration among edge servers. We formulate an optimization problem that aims to minimize the overall task response time and decompose it into a caching subproblem and a scheduling subproblem. By analyzing the properties of optimal solutions, we show that the optimal caching decisions can be efficiently searched using the bisection method. For the scheduling subproblem, we utilize projected gradient descent and backtracking to find a local minimum. Numerical results show that our algorithm significantly reduces the response time in various situations.

description: The study examined the consumer preference for processed milk in Mymensingh town. The study was mainly based on primary data in which 40 consumers were purposively selected from Mymensingh town. In the study, preference of consumers for processed milk i.e. powder milk, condensed milk and pasteurized milk were investigated. Consumers’ preference for processed milk was ascertained through a 4-point numerical rating scale. The consumers highly preferred powder milk and the computed preference index of powder milk was 80. The computed preference index of pasteurized milk was 71. The computed preference index of raw milk was 54. The lowest preference of consumers was for condensed milk and the computed preference index of condensed milk was 36. The study revealed that Milk Vita has ranked first (90) followed by Diploma (85), Dano (81), Arong (68) and Red Cow (61) were the major brands preferred by the consumers. On the other hand, Danish (36), Nido (34), Starship (34), Marks (27) and Farmland (26) were less preferred for consumption of processed milk. The relationship between the factors that influencing consumer’s preferences and their preferences of processed milk was also explored. Spearman rank correlation coefficient test was used to explore relationship between the variables. The monthly income of the family, price level, taste level, fat content, nutritional value and attitudes towards processed milk of the consumers were significantly related with their preferences of processed milk while the other factors (age, family size, education level) were not significantly related.

description: In Bangladesh, the majority of the deliveries in rural areas take place at homes with higher risk of morbidity and
mortality. Most Union Health and Family Welfare Centers (UHFWCs) do not have the provision to provide 24-hour
normal delivery services which is in close proximity of most of the rural women. With this point of view, the
Population Council has provided technical assistance to the Directorate General of Family Planning (DGFP) to
implement an Operations Research (OR) study in 24 UHFWCs of Chittagong and Munshiganj districts to test the
effectiveness of a model to strengthen UHFWCs so that they can provide 24-hour normal delivery services. Broadly,
three interventions, namely, human resource strengthening, community participation, and referral linkage
strengthening were implemented for 12 months. Six UHFWCs from Comilla district comparable to the intervention
UHFWCs served as control sites. A separate sample pre-test and post-test control group design was used to evaluate
the impact of the interventions.
Prior to the interventions, UHFWCs were widely known as a facility that provides family planning and mother and
child care services, followed by general illness services. Interventions have resulted in improving the awareness of
UHFWC’s 24-hour normal delivery services among women (Chittagong: Baseline 6%, Endline 40%; Munshiganj:
Baseline 0%, Endline 31%); yet, two-thirds of the women remain ignorant of UHFWC’s 24/7 normal delivery services.

description: Here, we present an algebraic and kinematical analysis of non-commutative $κ$-Minkowski spaces within Galilean (non-relativistic) and Carrollian (ultra-relativistic) regimes. Utilizing the theory of Wigner-Inönu contractions, we begin with a brief review of how one can apply these contractions to the well-known Poincaré algebra, yielding the corresponding Galilean (both massive and mass-less) and Carrollian algebras as $c \to \infty$ and $c\to 0$, respectively. Subsequently, we methodically apply these contractions to non-commutative $κ$-deformed spaces, revealing compelling insights into the interplay among the non-commutative parameters $a^μ$ (with $|a^ν|$ being of the order of Planck length scale) and the speed of light $c$ as it approaches both infinity and zero. Our exploration predicts a sort of "branching" of the non-commutative parameters $a^μ$, leading to the emergence of a novel length scale and time scale in either limit. Furthermore, our investigation extends to the examination of curved momentum spaces and their geodesic distances in appropriate subspaces of the $κ$-deformed Newtonian and Carrollian space-times. We finally delve into the study of their deformed dispersion relations, arising from these deformed geodesic distances, providing a comprehensive understanding of the nature of these space-times.

description: IGR J17591$-$2342 is a new accreting millisecond X-ray pulsar (AMXP) that was recently discovered in outburst in 2018. Early observations revealed that the source's radio emission is brighter than that of any other known neutron star low-mass X-ray binary (NS-LMXB) at comparable X-ray luminosity, and assuming its likely $\gtrsim 6$ kpc distance. It is comparably radio bright to black hole LMXBs at similar X-ray luminosities. In this work, we present the results of our extensive radio and X-ray monitoring campaign of the 2018 outburst of IGR J17591$-$2342. In total we collected 10 quasi-simultaneous radio (VLA, ATCA) and X-ray (Swift-XRT) observations, which make IGR J17591$-$2342 one of the best-sampled NS-LMXBs. We use these to fit a power-law correlation index $β= 0.37^{+0.42}_{-0.40}$ between observed radio and X-ray luminosities ( $L_\mathrm{R}\propto L_\mathrm{X}^β$). However, our monitoring revealed a large scatter in IGR J17591$-$2342's radio luminosity (at a similar X-ray luminosity, $L_\mathrm{X} \sim 10^{36}$ erg s$^{-1}$, and spectral state), with $L_\mathrm{R} \sim 4 \times 10^{29}$ erg s$^{-1}$ during the first three reported observations, and up to a factor of 4 lower $L_\mathrm{R}$ during later radio observations. Nonetheless, the average radio luminosity of IGR J17591$-$2342 is still one of the highest among NS-LMXBs, and we discuss possible reasons for the wide range of radio luminosities observed in such systems during outburst. We found no evidence for radio pulsations from IGR J17591$-$2342 in our Green Bank Telescope observations performed shortly after the source returned to quiescence. Nonetheless, we cannot rule out that IGR J17591$-$2342 becomes a radio millisecond pulsar during quiescence.
