description: New challenges in structural biology are driving the development of new technology, such as photon counting pixel array detectors, and new modes of data collection, such as serial synchrotron crystallography (SSX), in macromolecular crystallography at synchrotrons. This in turn is creating the need for better algorithms and software to extract the maximum amount of information from the diffraction data. The aim of this project is to develop statistically robust methods for the integration and analysis of X-ray diffraction data to address these challenges. A method for estimating the background under each reflection during integration that is robust in the presence of pixel outliers is presented. This uses a generalised linear model (GLM) approach that is more appropriate for use with Poisson distributed data than traditional approaches to pixel outlier handling in integration programs. The algorithm is most applicable to data with a very low background level where assumptions of a normal distribution are no longer valid as an approximation to the Poisson distribution. A second algorithm for modelling the background for each Bragg reflection in a series of X-ray diffraction images containing Debye-Scherrer diffraction from ice in the sample is also presented. This method involves the use of a global background model which is generated from the complete X-ray diffraction dataset. Fitting of this model to the background pixels is then done for each reflection independently. Finally, a model for the observed reflection profiles is described for the purpose of improving the refinement of the crystal unit cell and orientation for still image diffraction data collected at synchrotrons. This model consists of two components: a Normal distribution is used to describe the distribution of wavelengths and a Multivariate Normal distribution (MVN) is used to describe the distribution of reciprocal lattice vectors for each reflection; this allows non-isotropic spot shapes to be easily described. The parameters of the model are estimated from the data via a simple maximum likelihood algorithm. The algorithms are incorporated into the DIALS integration package.

The Formation of Massive Stars from Turbulent Cores
Creators: name: McKee, Christopher F.

Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Observations indicate that massive stars form in regions of very high surface density, ~1 g cm^-2. Clusters containing massive stars and globular clusters have a comparable column density. The total pressure in clouds of such a column density is P/k~10^8-10^9 K cm^-3, far greater than that in the diffuse ISM or the average in GMCs. Observations show that massive star-forming regions are supersonically turbulent, and we show that the molecular cores out of which individual massive stars form are as well. The protostellar accretion rate in such a core is approximately equal to the instantaneous mass of the star divided by the free-fall time of the gas that is accreting onto the star (Stahler, Shu, & Taam 1980). The star-formation time in this Turbulent Core model for massive star formation is several mean free-fall timesscales of the core, but is about equal to that of the region in which the core is embedded. The typical time for a massive star to form is about 10^5 yr and the accretion rate is high enough to overcome radiation pressure due to the luminosity of the star. For the typical case we consider, in which the cores out of which the stars form have a density structure varying as r^{-1.5}, the protostellar accretion rate grows linearly with time. We calculate the evolution of the radius of a protostar and determine the accretion luminosity. At the high accretion rates that are typical in regions of massive star formation, protostars join the main sequence at about 20 solar masses. We apply these results to predict the properties of protostars thought to be powering several observed hot molecular cores, including the Orion hot core and W3(H2O). In the Appendixes, we discuss the pressure in molecular clouds and we argue that ``logatropic'' models for molecular clouds are incompatible with observation.

description: The study focused on ascertaining the relative importance of aquaculture in the farming systems of Oil Producing Areas Delta State, Nigeria. A stratified random sample of 598 households from 47 communities was used. Primary data collected between the months of May 2009 and February 2011 by means of structured questionnaire, complemented by oral were analysed using both descriptive and inferential statistics. The results show that 69% of the respondents were into fishing/fish farming either as sole enterprise or in combination with other farming activities while 31% were into non-fish farming activities only. Among those involved in fishing activities, 37% were into capture fisheries, while about 32% were involved in aquaculture either as sole enterprise or in combination with other farming enterprises. The average size of fish pond was about 51 m2. The mean household net income from aquaculture per annum was about N91, 542, giving the highest returns on investment of about 45%. The study also found that households practicing aquaculture together with arable cropping generated significantly (P ≤ 0.05) highest net farm income (N127342) than the rest groups of households. The major constraints to aquaculture development were inadequate finance, high cost of feeds and water pollution problems. It was recommended that the current government efforts at boosting investment in aquaculture through microcredit should be stepped up. Local sourcing of feeds by the farmers is also encouraged.

description: In this work, we propose a novel Cycle In Cycle Generative Adversarial Network (C$^2$GAN) for the task of keypoint-guided image generation. The proposed C$^2$GAN is a cross-modal framework exploring a joint exploitation of the keypoint and the image data in an interactive manner. C$^2$GAN contains two different types of generators, i.e., keypoint-oriented generator and image-oriented generator. Both of them are mutually connected in an end-to-end learnable fashion and explicitly form three cycled sub-networks, i.e., one image generation cycle and two keypoint generation cycles. Each cycle not only aims at reconstructing the input domain, and also produces useful output involving in the generation of another cycle. By so doing, the cycles constrain each other implicitly, which provides complementary information from the two different modalities and brings extra supervision across cycles, thus facilitating more robust optimization of the whole network. Extensive experimental results on two publicly available datasets, i.e., Radboud Faces and Market-1501, demonstrate that our approach is effective to generate more photo-realistic images compared with state-of-the-art models.

description: Rural labor service economy is a method turning rural surplus human resources to economic resources, to realize increase of social wealth. Developing the rural labor service economy has profound influence on promoting transfer and employment of rural surplus labor, and speeding up industrialization and urbanization. Rural labor service economy is a huge and complex systematic project for promoting urban and rural integrated development and increasing farmers’ income. This paper firstly analyzed importance and urgency of accelerating the development of rural labor service economy. From the perspective of urban and rural integration, it came up with pertinent recommendations, including establishing security mechanism and improving rural labor security mechanism, creating preferential conditions and encouraging farmers to return to hometown, exploring potential and promoting nearby labor transfer to promote rapid economic development, improving public employment service system, and cultivating and developing labor market. It is expected to provide certain references.

(Figs 4–5)
 Material examined. S1 4–18.IV.06 1 ♂. SAR1 16.II–15.VI.04 1 ♂.
 Chorotype. Type 6 [3.01 of Vigna Taglianti et al. (1999)]. Mediterranean, previously known only from Greece (Pelopponese).
 Italian distribution. Sardinia only.
 Notes. Chandler and Blasco-Zumeta (2001) included descriptions of six species of the Pyratula perpusilla Edwards, 1925 group, mostly from the Mediterranean region, only P. perpusilla itself being known from northern Europe. Among the species described in that paper these specimens are concluded to be conspecific with P.takkae pending discovery of further material. They agree well in most characters of the male genitalia (Figs 4–5), in particular in the structure of the apical margin of the gonocoxites, which is characteristic in species of this group. The holotype of P. takkae was unusual in this genus in having strong setae on the mediotergite. These specimens differ in lacking these setae so in the absence of other material it is not possible to say which condition is typical of the species. The holotype has the head damaged and lacks flagellomeres. The Sardinian specimens have the antenna 1.5 times as long as the thorax and the flagellomeres are about twice as long as broad.
 Chandler (2004b) recorded P. perpusilla as new to Italy from Bosco della Fontana and Kurina (2008) recorded two species of this group from South Tyrol, P. alpicola Chandler, 2001 (also known from Czech Republic, the Swiss Alps and Andorra) and P. oracula Chandler, 1994 (mainly Mediterranean but also occurring in Czech Republic and Switzerland). The finding of this species in Sardinia is thus of considerable interest, identifying Italy as having the richest known fauna of this genus.

In general, we find short distance lattice data to be well described by ``boosted perturbation theory''. For Wilson-type fermions at present-day quark masses and lattice spacings agreement within 10% between measured ``$β$-shifts'' and those predicted by perturbation theory is found. We comment on prospects for a determination of the real world QCD running coupling.

description: A study was undertaken in three important vegetable producing areas to determine the plant-parasitic nematodes associated with hedge trees and a pot experiment was conducted to assess hedge trees (Acacia senegal, Bauhinia rufescens and Prosopis juliflora) behavior to the root-knot-nematode, Meloidogyne javanica. Soil and roots analysis revealed the presence of 10 genera of plant-parasitic nematodes, including M. javanica. The behavior test seems to indicate that all three plants were susceptible to Meloidogyne javanica with root gall index ranging from 1 to 2.8, and nematode multiplication rate ranging from 2.78 to 5.70.

description: We consider SU($3$) fermions on the triangular lattice in the presence of a gauge potential which stabilizes a quantum Hall insulator (QHI) at the density of one particle per lattice site. We investigate the effect of the Hubbard interaction, favoring magnetic long-range order, and a three-sublattice potential (TSP), favoring a normal insulator (NI), on the system. For weak TSP we find that the Hubbard interaction drives the QHI into a three-sublattice magnetic Mott insulator (MMI). For intermediate values of TSP we identify two transition points upon increasing the Hubbard interaction. The first transition is from the NI to the QHI and the second transition is from the QHI to the MMI. For large values of the TSP a charge-ordered magnetic insulator (COMI) emerges between the NI and the QHI, leading to an interaction-driven COMI-to-QHI transition.

description: A novel macroporous strong acidic cation exchange resin (D001) modified by nano-sized goethite (nFeOOH@D001) was fabricated by using a facile ethanol dispersion and impregnation method, and its efficiency for Cr(VI) removal was tested thereafter. Due to the dispersing effect of ethanol, FeOOH particles of 20–150 nm were coated on the D001 surfaces. The nFeOOH@D001 obtained a Cr(VI) removal efficiency and capacity of 80.2% and 7.4 mg/g respectively, 5 times and 8 times higher than that of the pristine D001. The Cr(VI) removal by nFeOOH@D001 followed the pseudo second-order kinetics and the Langmuir adsorption model. Column experiments also demonstrated that the nFeOOH@D001 exhibited a much better ability to remove Cr(VI) as compared to the D001. Additionally, the nFeOOH@D001 showed a potential for reusability and renewability. The adsorbed nFeOOH@D001 could be easily desorbed by 0.1 M acetic acid and a reuse efficiency of 92.7% could be maintained after 4 desorption–adsorption cycles. The used nFeOOH@D001 could be eluted by 0.1 M HCl to remove nFeOOH, and the renewed D001 could be recoated by nFeOOH and achieved a regeneration rate of 97.8% for Cr(VI) removal. The above results indicated that nano-sized goethite modification is a promising method to endow D001 with the ability to remove Cr(VI) from water.

description: We investigate the nature of the low-energy, large-scale excitations in the three-dimensional Edwards-Anderson Ising spin glass with Gaussian couplings and free boundary conditions, by studying the response of the ground state to a coupling-dependent perturbation introduced previously. The ground states are determined exactly for system sizes up to 12^3 spins using a branch and cut algorithm. The data are consistent with a picture where the surface of the excitations is not space-filling, such as the droplet or the ``TNT'' picture, with only minimal corrections to scaling. When allowing for very large corrections to scaling, the data are also consistent with a picture with space-filling surfaces, such as replica symmetry breaking. The energy of the excitations scales with their size with a small exponent θ', which is compatible with zero if we allow moderate corrections to scaling. We compare the results with data for periodic boundary conditions obtained with a genetic algorithm, and discuss the effects of different boundary conditions on corrections to scaling. Finally, we analyze the performance of our branch and cut algorithm, finding that it is correlated with the existence of large-scale,low-energy excitations.

description: The James Webb Space Telescope (JWST) is expected to enable transformational progress in studying galaxy populations in the very early Universe, during the Epoch of Reionization (EoR). A critical parameter for understanding the sources that reionized the Universe is the Lyman-continuum production efficiency, $ξ_{\rm ion}$, defined as the rate of production of ionizing photons divided by the intrinsic UV luminosity. In this work, we combine self-consistent star formation and chemical enrichment histories predicted by semi-analytic models of galaxy formation with stellar population synthesis (SPS) models to predict the expected dependence of $ξ_{\rm ion}$ on galaxy properties and cosmic epoch from $z=4-10$. We then explore the sensitivity of the production rate of ionizing photons, $\dot{N}_{\rm ion}$, to the choice of SPS model and the treatment of stellar feedback in our galaxy formation model. We compare our results to those of other simulations, constraints from empirical models, and observations. We find that adopting SPS models that include binary stars predict about a factor of two more ionizing radiation than models that only assume single stellar populations. We find that UV-faint, low-mass galaxies have values of $ξ_{\rm ion}$ about 0.25 dex higher than those of more massive galaxies, but find weak evolution with cosmic time, about 0.2 dex from $z\sim 12-4$ at fixed rest-UV luminosity. We provide predictions of $\dot{N}_{\rm ion}$ as a function of $M_{\rm h}$ and a number of other galaxy properties. All results presented in this work are available at https://www.simonsfoundation.org/semi-analytic-forecasts-for-jwst/.

description: The thermodynamic properties for three different types of off-lattice four-strand beta-sheet protein models interacting via a hybrid Go-type potential have been investigated. Discontinuous molecular dynamic simulations have been performed for different sizes of the bias gap g, an artificial measure of a model protein's preference for its native state. The thermodynamic transition temperatures are obtained by calculating the squared radius of gyration, the root-mean-squared pair separation fluctuation, the specific heat, the internal energy of the system, and the Lindemann disorder parameter. In spite of the simplicity, the protein-like heteropolymers have shown a complex set of protein transitions as observed in experimental studies. Starting from high temperature, these transitions include a collapse transition, a disordered-to-ordered globule transition, a folding transition, and a liquid-to-solid transition. These transitions strongly depend on the native-state geometry of the model proteins and the size of the bias gap. A strong transition from the disordered globule state to the ordered globule state with large energy change and a weak transition from the ordered globule state to the native state with small energy change were observed for the large gap models. For the small gap models no native structures were observed at any temperature, all three beta-sheet proteins fold into a partially-ordered globule state which is geometrically different from the native state. For small bias gaps at even lower temperatures, all protein motions are frozen indicating an inactive solid-like phase.

description: Gastrodigenin, also known as 4-hydroxybenzyl alcohol (HBA), is one of the main components of Gastrodia elata, which is a perfect lead compound of natural products. In order to get new active compounds, we modified the structure of HBA through esterification with carboxylic acid, and got a series of derivatives in which 4-hydroxybenzyl alcohol 2-naphthoate (NHBA) showed stronger antidepressant activity than HBA. In this paper, we firstly evaluated the antidepressant activity of NHBA by tail suspension test (TST) and forced swimming test (FST). Then, we carried out the biochemical assay and western blot to determine its mechanism. The results displayed that NHBA could increase the content of serotonin, dopamine, norepinephrine, γ-aminobutyric acid, brain-derived neurotrophic factor (BDNF) and tropomyosin receptor kinase B (TrkB) in mice brain. It suggested that NHBA exhibited an antidepressant-like effect through monoaminergic system, GABAergic system and BDNF/TrkB signaling pathways.

description: In this thesis, we study a class of reaction-diffusion equations of the form $\frac{\partial u}{\partial t} = \mathcal{L}u + \phi u - \tfrac{1}{k} u^{k+1}$ where $\mathcal{L}$ is the stochastic generator of a Markov process, $\phi$ is a function of the space variables and $k\in \mathbb{R}\backslash\{0\}$. An important example, in the case when $k>0$, is equations of the FKPP-type. We also give an example from the theory of utility maximisation problems when such equations arise and in this case $k<0$. We introduce a new representation, for the solution of the equation, as the optimal value of an optimal control problem. We also give a second representation which can be seen as a dual problem to the first optimisation problem. We note that this is a new type of dual problem and we compare it to the standard Lagrangian dual formulation. By choosing controls in the optimisation problems we obtain upper and lower bounds on the solution to the PDE. We use these bounds to study the speed of the wave front of the PDE in the case when $\mathcal{L}$ is the generator of a suitable Lévy process.

description: Colloidosomes are microcapsules whose shells consist of colloid particles, which are coagulated by a stabiliser or fused by sintering. In recent years, they have attracted considerable attention because of their potential applications in a range of industries, such as food, bioreactors and medicine. However, traditional particulate polymer shell colloidosomes leak low molecular weight encapsulated materials due to their intrinsic shell permeability, and this problem will limit their applications in pharmaceutical industries. In this thesis, we report aqueous core colloidosomes coated with a silver or gold shell, which make the capsules impermeable. The shells can be ruptured using ultrasound. The silver shells are prepared by making an aqueous core capsule with a particulate polymer shell and then adding AgNO3, surfactant and L-ascorbic acid to form a second shell. The gold coated colloidosomes are prepared by making an aqueous core capsule with a particulate polymer shell and then adding HAuCl4, surfactant and L-ascorbic acid. We propose to use the metal coated capsules as drug carriers to load an anticancer drug, doxorubicin. After triggering by ultrasound, encapsulated drug, broken fragments and possibly some drug attached on the surface of the capsules may all kill cancer cells. For silver coated colloidosomes, at 10 capsules/cell, they have a low cytotoxicity, showing a cell viability of more than 90% during the ﬁrst 24 h and more than 60% after 72 h. Increasing the number of capsules, the cytotoxicity of the silver shells increases heavily. Compared with silver ones, the gold shells show less toxicity to cells. We also used the capsules to load an antibiotic kanamycin and triggered to release the drug and kill E.coli. In addition, we set up a targeting model by modifying the colloidosomes using 4,4’-dithiodibutyric acid and attaching them with proteins - rabbit Immunoglobulin G (IgG). Label-free Surface Plasmon Resonance biosensor was used to test the specific targeting of the functional silver or gold shells with rabbit antigen. The results demonstrate that a new type of functional metal coated colloidosome with non-permeability, ultrasound sensitivity and immunoassay targeting could be applied to many medical applications.

description: This paper, from the city integration perspective, analyzes the main beneficiaries who benefit from the household registration system reform, and studies the influence of individual decisions about the transfer from agriculture to non-agriculture. Based on it, this paper makes an empirical research by using the survey data about migrant workers in Chongqing. The research findings are as follows: (i) The urban employment, the living condition and the rural connection have a significant impact on migrant workers’ transfer decision; (2) If the value of those factors (such as the working stability, the family income, the urban house condition and the urban social security) is higher, then the migrant workers who have no economic interest in rural areas are better able to integrate into the urban areas, therefore the inclination to transfer the household registration from agriculture to non-agriculture will be much stronger. It is proposed that we should do some significant things, such as enhancing the investment of security housing, bringing the migrant workers into the city housing accumulation fund system and giving them prior allocation right, perfecting land elastic exit mechanism, creating a harmonious employment environment, which are important strategies promoting migrant workers to integrate into the urban areas and affecting their individual decision about transferring from agriculture to non-agriculture.

description: Time series are series of values ordered by time. This kind of data can be found in many real world settings. Classifying time series is a difficult task and an active area of research. This paper investigates the use of transfer learning in Deep Neural Networks and a 2D representation of time series known as Recurrence Plots. In order to utilize the research done in the area of image classification, where Deep Neural Networks have achieved very good results, we use a Residual Neural Networks architecture known as ResNet. As preprocessing of time series is a major part of every time series classification pipeline, the method proposed simplifies this step and requires only few parameters. For the first time we propose a method for multi time series classification: Training a single network to classify all datasets in the archive with one network. We are among the first to evaluate the method on the latest 2018 release of the UCR archive, a well established time series classification benchmarking dataset.

description: Quantum technologies exploit entanglement to enhance various tasks beyond their classical limits including computation, communication and measurements. Quantum metrology aims to increase the precision of a measured quantity that is estimated in the presence of statistical errors using entangled quantum states. We present a novel approach for finding (near) optimal states for metrology in the presence of noise, using variational techniques as a tool for efficiently searching the classically intractable high-dimensional space of quantum states. We comprehensively explore systems consisting of up to 9 qubits and find new highly entangled states that are not symmetric under permutations and non-trivially outperform previously known states up to a constant factor 2. We consider a range of environmental noise models; while passive quantum states cannot achieve a fundamentally superior scaling (as established by prior asymptotic results) we do observe a significant absolute quantum advantage. We finally outline a possible experimental setup for variational quantum metrology which can be implemented in near-term hardware.

description: Smartphones are quickly moving toward complementing or even replacing traditional car keys. We advocate a role-based access control policy mixed with attributes that facilitates access to various functionalities of vehicular on-board units from smartphones. We use a rights-based access control policy for in-vehicle functionalities similar to the case of a file allocation table of a contemporary OS, in which read, write or execute operations can be performed over various vehicle functions. Further, to assure the appropriate security, we develop a protocol suite using identity-based cryptography and we rely on group signatures that preserve the anonymity of group members for assuring privacy and traceability. To prove the feasibility of our approach, we develop a proof-of-concept implementation with modern smartphones, aftermarket Android head-units and test computational feasibility on a real-world in-vehicle controller. Our implementation relies on state-of-the-art cryptography, including traditional building blocks and more modern pairing-friendly curves, that facilitate the adoption of group signatures and identity-based cryptography in automotive-based scenarios.

description: The lifetime splitting between the B^+ and B_d^0 mesons has recently been calculated in the next-to-leading order of QCD. These corrections are necessary for a reliable theoretical prediction, in particular for the meaningful use of hadronic matrix elements computed with lattice QCD. Using results from quenched lattice QCD we find tau(B^+)/tau(B^0_d)=1.053 +/- 0.016 +/- 0.017, where the uncertainties from unquenching and 1/m_b corrections are not included. The lifetime difference of heavy baryons Xi_b^0 and Ξ_b^- is also discussed.

Quantization of the mean decay time for non-Hermitian quantum systems

description: We show that the mean time, which a quantum particle needs to escape from a system to the environment, is quantized and independent from most dynamical details of the system. In particular, we consider a quantum system with a general Hermitian Hamiltonian $\hat{H}$ and one decay channel, through which probability dissipates to the environment with rate $Γ$. When the system is initially prepared exactly in the decay state, the mean decay time $\langle T \rangle$ is quantized and equal to $w/(2Γ)$. $w$ is the number of distinct energy levels, i.e. eigenvalues of $\hat{H}$, that have overlap with the decay state, and is also the winding number of a transform of the resolvent in the complex plane. Apart from the integer $w$, $\langle T \rangle$ is completely independent of the system's dynamics. The complete decay time distribution can be obtained from an electrostatic analogy and features rare events of very large dissipation times for parameter choices close to critical points, where $w$ changes, e.g. when a degeneracy is lifted. Experiments of insufficient observation time may thus measure a too small value of $w$. We discuss our findings in a disordered tight-binding model and in the two-level atom in a continuous-wave field.

Dusty Cloud Acceleration with Multiband Radiation

description: We perform two-dimensional and three-dimensional simulations of cold, dense clouds, which are accelerated by radiation pressure on dust relative to a hot, diffuse background gas. We examine the relative effectiveness of acceleration by ultraviolet and infrared radiation fields, both independently and acting simultaneously on the same cloud. We study clouds that are optically thin to infrared emission but with varying ultraviolet optical depths. Consistent with previous work, we find relatively efficient acceleration and long cloud survival times when the infrared band flux dominates over the ultraviolet flux. However, when ultraviolet is dominant or even a modest percentage ($\sim 5-10$\%) of the infrared irradiating flux, it can act to compress the cloud, first crushing it and then disrupting the outer layers. This drives mixing of outer regions of the dusty gas with the hot diffuse background to the point where most dust is not likely to survive or stay coupled to the gas. Hence, the cold cloud is unable to survive for a long enough timescale to experience significant acceleration before disruption even though efficient infrared cooling keeps the majority of the gas close to radiative equilibrium temperature ($T \lesssim 100$K). We discuss implications for observed systems, concluding that radiation pressure driving is most effective when the light from star-forming regions is efficiently reprocessed into the infrared.

description: In order to better reproduction of the information that is as close as possible to reality, we have established a procedure for analyzing images based on visual interpretation and digital processing. In digital processing, supervised classification by maximum likelihood, based on a fieldwork allowed to discriminate elements of land. Recovery of geometric shapes by scanning fallow and bare soil from panchromatic Spot image yielded the map of agrarian structures. Different queries and statistical operations performed were used to assess the areas of agrarian structures. The analysis of the dynamics of agrarian structures showed that the period 1986 - 2000 was marked by environmental degradation, while the period 2000 - 2004 has seen a regeneration of the natural environment. Treatments applied to images and ensuing results indicate the feasibility of monitoring by remote sensing of agricultural structures in northeastern area of Côte d'Ivoire. This research shows that the Geographic Information System is an effective tool for the evaluation of agrarian structures. However, manual scanning of elements in the environment requires careful attention to avoid skewing the results.

description: On the basis of analyzing the consumption status of rural residents in Kongpo, it can be seen that the concept of consumption value of rural residents in Kongpo tends to be cautious in daily consumption. There also exist premature consumption and excessive consumption that are centralized, seasonal and religious. This paper aims to put forward countermeasures and suggestions for guiding the rural residents in Kongpo to develop a scientific concept of consumption value in the light of the factors that restrict the formation of scientific consumption value among rural residents.
