description: Programs expecting structured inputs often consist of both a syntactic analysis stage, which parses raw input, and a semantic analysis stage, which conducts checks on the parsed input and executes the core logic of the program. Generator-based testing tools in the lineage of QuickCheck are a promising way to generate random syntactically valid test inputs for these programs. We present Zest, a technique which automatically guides QuickCheck-like randominput generators to better explore the semantic analysis stage of test programs. Zest converts random-input generators into deterministic parametric generators. We present the key insight that mutations in the untyped parameter domain map to structural mutations in the input domain. Zest leverages program feedback in the form of code coverage and input validity to perform feedback-directed parameter search. We evaluate Zest against AFL and QuickCheck on five Java programs: Maven, Ant, BCEL, Closure, and Rhino. Zest covers 1.03x-2.81x as many branches within the benchmarks semantic analysis stages as baseline techniques. Further, we find 10 new bugs in the semantic analysis stages of these benchmarks. Zest is the most effective technique in finding these bugs reliably and quickly, requiring at most 10 minutes on average to find each bug.

description: α-Amylase has been considered an important therapeutic target for the management of type 2 diabetes mellitus (T2DM), decreasing postprandial hyperglycaemia (PPHG). In the present work, a panel of 40 structurally related flavonoids was tested, concerning their ability to inhibit α-amylase activity, using a microanalysis screening system, an inhibitory kinetic analysis and molecular docking calculations. From the obtained results, it was possible to observe that the flavone with a -Cl ion at 3-position of C-ring, an –OH group at 3′- and 4′- positions of B-ring and at 5- and 7- positions of A-ring and the C2 = C3 double bond, was the most active tested flavonoid, through competitive inhibition. In conclusion, some of the tested flavonoids have shown promising inhibition of α-amylase and may be considered as possible alternatives to the modulation of T2DM.

Selected NEMS and MEMS state-of-art technologies could be used for inspections at Guiana Space Center without dismounting and sending to Europe for industrial check. A few examples of micro and nano equipment\'s such as robot (tools), or nano camera, for detection and data collection are underlined in the article and a preparation tests campaign is prepared according to precise specifications coming from RLV equipment. This feasibility study is the first attempt to use these technologies in order to cope with the MRO RLV and start to contribute at a maintenance characterization economic model.

description: We investigate the dc current-voltage characteristics of d-wave Josephson junctions, where the barrier at the interface may have arbitrary strength. Dividing the current into n-particle currents $I_n$ (n integer), we can explicitly show which physical processes are responsible for the subharmonic gap structure (SGS). For orientations where midgap states (MGS) exist, the resonances in the n-particle processes are drastically changed, giving rise to a strongly modified SGS. Introducing broadening in a phenomenological way, we show that MGS may produce a current peak near zero bias and we explain which physical processes are contributing to this peak. The agreement of our theory with recent experiments is discussed.

description: We discuss the existence of Galois relations obeyed by certain link invariants. Some of these relations have recently been identified and exploited within the context of CFT and Lie/Kac-Moody representation theory. These relations should aid in computing knot invariants. They probably have an interpretation in terms of quasitriangular (quasi-)Hopf algebras. They could also have a topological interpretation, and may serve as a concrete model for related ideas of Degiovanni, Drinfeld, Grothendieck, Ihara, and others.

Similarity renormalization group evolution of hypernuclear Hamiltonians
Creators: name: Wirth, Roland
name: Roth, Robert
Publisher: name: arXiv
Year: 2019
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: Unitary transformations of a Hamiltonian generally induce interaction terms beyond the particle rank present in the untransformed Hamiltonian that have to be captured and included in a many-body calculation. In systems with strangeness such as hypernuclei, the three-body terms induced by the hyperon-nucleon interaction are strong, so their inclusion is crucial. We present in detail a procedure for computing hyperon-nucleon-nucleon interaction terms that are induced during a similarity renormalization group (SRG) flow. The SRG is carried out in a basis spanned by antisymmetric harmonic-oscillator states with respect to three-body Jacobi coordinates. We discuss basis construction, antisymmetrization, numerical evaluation of the flow equations, and separation of the genuine three-body terms. We then use the hypernuclear no-core shell model with SRG-evolved Hamiltonians, addressing the sensitivity of hypernuclear states and hyperon separation energies to changes in the nucleonic Hamiltonian by example of $^7_Λ$Li, $^9_Λ$Be, $^{11}_Λ$B, $^{13}_Λ$C, and the hyper-helium chain. We also present a survey of the hyper-hydrogen chain, exploring the structure of hypernuclei with extreme neutron-proton asymmetries.

Finite Temperature Magnetism in Fractional Quantum Hall Systems: Composite Fermion Hartree-Fock and Beyond
Creators: name: Murthy, Ganpathy
Publisher: name: arXiv
Year: 2000
Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: Using the Hamiltonian formulation of Composite Fermions developed recently, the temperature dependence of the spin polarization is computed for the translationally invariant fractional quantum Hall states at $ν=1/3$ and $ν=2/5$ in two steps. In the first step, the effect of particle-hole excitations on the spin polarization is computed in a Composite Fermion Hartree-Fock approximation. The computed magnetization for $ν=1/3$ lies above the experimental results for intermediate temperatures indicating the importance of long wavelength spin fluctuations which are not correctly treated in Hartree-Fock. In the second step, spin fluctuations beyond Hartree-Fock are included for $ν=1/3$ by mapping the problem on to the coarse-grained continuum quantum ferromagnet. The parameters of the effective continuum quantum ferromagnet description are extracted from the preceding Hartree-Fock analysis. After the inclusion of spin fluctuations in a large-N approach, the results for the finite-temperature spin polarization are in quite good agreement with the experiments.

A few cases are analysed in details taking into account the results of tests campaign in ATEX environment of the LOX and LH2 storage and productions areas realized with an ATEX drone at European Spaceport in French Guiana in 2018. These results have notably demonstrated the feasibility of detection of gas leaks, thermal isolation defects and hot points before authorizing the approach of any human operator to the launch vehicle. The state of art infrared and optical sensors is presented in order to anticipate and foresee inspections operations for the vehicle landing.
Analysis of the spatially-resolved $V$-3.6$μ$m colors and dust extinction in 257 nearby NGC and IC galaxies

description: We present and analyze spatially-resolved maps for the observed $V$- and $g$-band to 3.6$μ$m flux ratios and the inferred dust extinction values, $A_V$, for a sample of 257 nearby NGC and IC galaxies. Flux ratio maps are constructed using PSF-matched mosaics of SDSS $g$- and $r$-band images and Spitzer/IRAC 3.6$μ$m mosaics, with all pixels contaminated by foreground stars or background objects masked out. By applying the $β_V$ method (Tamura et al. 2009, 2010), which was recently calibrated as a function of redshift and morphological type by Kim, Jansen, & Windhorst (2017), dust extinction maps were created for each galaxy. The typical 1-$σ$ scatter in $β_V$ around the average, both within a galaxy and in each morphological type bin, is $\sim$20%. Combined, these result in a $\sim$0.4 mag scatter in $A_V$. $β_V$ becomes insensitive to small-scale variations in stellar populations once resolution elements subtend an angle larger than that of a typical giant molecular cloud ($\sim$200pc). We find noticeably redder $V$$-$3.6$μ$m colors in the center of star-forming galaxies and galaxies with a weak AGN. The derived intrinsic $V$$-$3.6$μ$m colors for each Hubble type are generally consistent with the model predictions of Kim et al. (2017). Finally, we discuss the applicability of the $β_V$ dust-correction method to more distant galaxies, for which well-matched HST rest-frame visible and JWST rest-frame $\sim$3.5$μ$m images will become available in the near-future.

description: This paper considers the influence of Reynolds number on the transition behavior of a dual-bell nozzle with special regard to hysteresis. For this purpose, Reynolds averaged Navier-Stokes (RANS) as well as large-eddy simulations (LES) are performed for a dual-bell nozzle applying a time dependent chamber pressure. Besides turbulent flow conditions, also laminar flows are assumed, i.e., the solutions are sought without considering any turbulence model. The comparison of numerical and experimental results shows a consistent shift of the transition to lower values for turbulent flow.

description: A resummation of ladder graphs is important in cases where infrared, collinear, or light-cone singularities render the loop expansion invalid, especially at high temperature where these effects are often enhanced. It has been noted in some recent examples of this resummation that the ladder graphs are canceled by other types of terms. In this note we show that this cancellation is quite general, and for the most part algebraic.

description: This thesis explores the triggers for 'spectator violence' at football matches. Reviewing two approaches, the social problem approach and the 'moral panic' approach, this research concludes violence lies within nationalism as an ideology in defense of the football 'nation'. It explores multiple terms associated with sports violence and operationalizes the complex terms associated with 'nation-ness' (nationalism, 'nation', and nationality). The final evidence is given through the violent football riot between Dinamo Zagreb and Red Star Belgrade on the 13th of May, 1990. This bloody football event became the starting point for the Croatian War for Independence. Within this case study is undeniable evidence for nationalism as the trigger for violence. While discussing other factors for violence, this paper concludes with questions for future research and what analysts should consider in future football violence.

description: Biotherapeutics, such as those derived from monoclonal antibodies (mAbs), are industrially produced in controlled multiunit operation bioprocesses. Each unit operation contributes to the final characteristics of the bioproduct. The complexity of the bioprocesses, the cellular machinery, and the bioproduct molecules, typically leads to inherent heterogeneity and variability of the final critical quality attributes (CQAs). In order to improve process control and increase product quality assurance, online and real-time monitoring of product CQAs is most relevant. In this review, the recent advances in CQAs monitoring of biotherapeutic drugs, with emphasis on mAbs, and throughout, the different bioprocess unit operations are reviewed. Recent analytical techniques used for assessment of product-related CQAs of mAbs are considered in light of the analytical speed and ability to measure different CQAs. Furthermore, the state of art modeling approaches for CQA estimation in real-time are presented as a viable alternative for real-time bioproduct CQA monitoring under the process analytical technology and quality-by-design frameworks in the biopharmaceutical industry, which have recently been demonstrated.
Sanctuaries in the Sardinian Bronze Age and Early Iron Age landscape (1200-700 BC): Network analysis and GIS approach
Creators: name: Matta, Valentina
Publisher: name: Layers. Archeologia Territorio Contesti
Year: 2020

description: This paper aims to investigate the role of the sanctuaries in regards to the settlement-pattern, control of metal resources and mobility of those resources during the Final Bronze Age (1200-900 BC) and Early Iron Age (900-700 BC) in Nuragic Sardinia. The rise of Nuragic sanctuaries relates as a response to a profound societal and economic crisis that invests the Nuragic civilization around 1200 BC. Defined as ‘territorial compounds’ and generally associated with the cult of water, the rise of these new types of settlements corresponds also to a period of increasing metal production, internal and external metal trade. However, their role in a model that investigates the control, exchange and the internal mobility of metal resources have never been conceptualized or tested. In this paper, I argue that the rise of the sanctuaries acted as symbolic, territorial and economic nodes within and between Nuragic settlements and natural resources. The study takes advantage of spatial analysis applied with two different methods: Terrain analyses through GIS and Network Analysis. Cost Surface Analysis and Least Cost Path to investigate mobility patterns between sanctuaries, settlements and metal resources. The results will be used in the Network Analysis to understand the role of sanctuaries in connection to the exchange of metal resources among settlements.

Determination of the CKM angle gamma and |V_{ub}/V_{cb}| from inclusive direct CP asymmetries and branching ratios in charmless B decays

description: We have calculated inclusive direct CP-asymmetries for charmless B^{+/-} -decays. After summing large logarithms to all orders the CP-asymmetries in Delta S=0 and Delta S=1 decays are found as a_{CP} (Delta S=0) = (2.0 +1.2/-1.0)% and a_{CP} (Delta S=1) = ( -1.0 +/- 0.5)%. These results are much larger than previous estimates based on a work without summation of large logarithms. We further show that the dominant contribution to a_{CP} (ΔS=0 ) is proportional to (sin gamma) times |V_{cb}/V_{ub}|. The constraints on the apex (rho-bar,eta-bar) of the unitarity triangle obtained from these two CP-asymmetries define circles in the (rho-bar,eta-bar)-plane. We have likewise analyzed the information on the unitarity triangle obtainable from a measurement of the average non-leptonic branching ratios Br(Delta S=0), Br(Delta S=1) and their sum Br_{NL} (B --> no charm). These CP-conserving quantities define circles centered on the rho-bar--axis of the (rho-bar,eta-bar)-plane. We expect a determination of |V_{ub}/V_{cb}| from Br_{NL} (B --> no charm) to be promising. Our results contain some new QCD corrections enhancing Br(Delta S=1), which now exceeds Br(Delta S=0) by roughly a factor of two.

title: A Method for Estimating Motions of Contours with an Application to Gait Recognition
Creators: name: Gelman, Sam

Subjects: subject: Computer vision

subject: Contour
subject: Distance transform

description: In this thesis, I propose a novel method for estimating motions between image contours. The method is fast and can handle both small and large displacements. It uses the distance transform and its gradients to estimate correspondences between points. The distance transform of a binary contour represents the distance of each pixel to the nearest contour pixel. The gradient of the distance transform points in the direction normal to the contour. By combining unit vectors obtained from the gradient with the original distance transform, the method produces vectors that correspond to the normal displacement between pairs of contours. This method can then be extended to compute true motion near corners as well as parameterized motion models. Experiments on various shape contours show the method's efficacy in computing normal displacements. Cases that do not correspond to normal motion are analyzed and corrected through the use of contour normals and motion models. The method is also applied to gait recognition, the goal of which is to identify people in videos based on their unique walking pattern. Many gait recognition methods operate on sequences of binary silhouettes. Since contours are easily obtainable from silhouettes, the proposed method is well-suited to the task. I describe two representations, the Histogram of Motion and the Edge Motion Vector, that allow for the comparison of contour motion between frames and sequences. These representations are tested on a large gait recognition database and achieve rank 1 and rank 5 performance that is comparable to the state of the art. The success of the method on gait recognition shows it is useful as a standalone representation, but it can also be used to improve other techniques and for other applications - this is left to future work.

description: Soil moisture is a critical parameter for predicting and detecting floods and droughts, as well as indicating crop and vegetation health. Current indicators utilize surrogate or modeled measures of soil moisture. Actual observed soil moisture measurements have the potential to improve understanding of floods, droughts, and crop health. In this study, ground soil moisture daily average values were compared to estimates obtained from two microwave sensors, the EOS Aqua Advanced Microwave Scanning Radiometer (AMSR-E) and the Tropical Rainfall Measurement Mission Microwave Scanning Radiometer (TMI), as well as one optical sensor, the EOS Aqua Moderate Resolution Imaging Spectroradiometer (MODIS). The study areas were the Little Washita River Experimental Watershed in Oklahoma and the Little River Experimental Watershed in Georgia. This research compared AMSR-E, TMI, and MODIS data to ground data from the Little Washita Berg station and also compared AMSR-E and TMI data to ground data from the Little River Soil Climate Analysis Network station. AMSR-E and TMI performed better in Little Washita than in Little River during the crop-covered season. This may be due to the vegetation type, distribution, and density at Little River. AMSR-E exhibited a smaller range of variability than the TMI or in-situ measurements at both study sites for all time periods. In the crop-covered season of June, July, and August of 2003, MODIS soil moisture retrieval at the Little Washita site correlated better (R^2 = 0.772) with the in-situ measurements than AMSR-E or TMI soil moisture retrievals. The spatial resolution of MODIS (1 km) is finer than the spatial resolution of AMSR-E (~25 km) or TMI. Spatial resolution is an important factor because topography, soil properties, and vegetation cover may vary significantly over satellite footprints. Both microwave sensors are limited by their coarse spatial resolution. However, optical measurements are limited to cloud-free conditions. Future work includes research on algorithms which combine optical and microwave measurements to provide the advantages of each.

description: We consider interface fluctuations on a two-dimensional layered lattice where the couplings follow a hierarchical sequence. This problem is equivalent to the diffusion process of a quantum particle in the presence of a one-dimensional hierarchical potential. According to a modified Harris criterion this type of perturbation is relevant and one expects anomalous fluctuating behavior. By transfer-matrix techniques and by an exact renormalization group transformation we have obtained analytical results for the interface fluctuation exponents, which are discontinuous at the homogeneous lattice limit.

description: We consider how the Hamiltonian Quantum Computing scheme introduced in [arXiv:1509.01278] can be implemented using a 2D array of superconducting transmon qubits. We show how the scheme requires the engineering of strong attractive cross-Kerr and weak flip-flop or hopping interactions and we detail how this can be achieved. Our proposal uses a new electric circuit for obtaining the attractive cross-Kerr coupling between transmons via a dipole-like element. We discuss and numerically analyze the forward motion and execution of the computation and its dependence on coupling strengths and their variability. We extend [arXiv:1509.01278] by explicitly showing how to construct a direct Toffoli gate, thus establishing computational universality via the Hadamard and Toffoli gate or via controlled-Hadamard, Hadamard and CNOT.

description: Facebook, as a popular representative of the social network site genre, has changed the way that social network site users manage their on- and offline social lives and communication, and creates a new rhetorical situation in which users create and perform their identity roles to an unknown audience. This new rhetorical situation requires connectivity, integration, and an understanding of both self as a performer of identity and as a member of a greater audience of other performers. Facebook creates Facebook-specific social action. This social action can be seen in how users manage their social information, communicate, and gather and share information. This thesis is framed by Lloyd F. Bitzer’s theory on elements of rhetorical situation (exigence, constraints, audience, and author) and is inspired by Carolyn Miller and Dawn Shepherd’s genre study of blogs, “Blogging as Social Action: A Genre Analysis of the Weblog.” Bitzer’s theory and Miller and Shepherd’s method assist in demonstrating that social network sites, and Facebook specifically, are functioning rhetorically and are a fitting rhetorical response to American social exigences.

description: We provide evidence of an extremely slow thermalization occurring in the Discrete NonLinear Schrödinger (DNLS) model. At variance with many similar processes encountered in statistical mechanics - typically ascribed to the presence of (free) energy barriers - here the slowness has a purely dynamical origin: it is due to the presence of an adiabatic invariant, which freezes the dynamics of a tall breather. Consequently, relaxation proceeds via rare events, where energy is suddenly released towards the background. We conjecture that this exponentially slow relaxation is a key ingredient contributing to the non-ergodic behavior recently observed in the negative temperature region of the DNLS equation.

Neutralino decay in the $μ$-problem solvable extra U(1) models

description: We study the neutralino decay in the supersymmetric extra U(1) models which can solve the $μ$-problem. In these models the neutralino sector is extended at least into six components by an extra U(1) gaugino and a superpartner of a singlet Higgs. Focussing on its two lower mass eigenstates $\tildeχ_2^0$ and $\tildeχ_1^0$, decay processes such as a tree level three body decay $\tildeχ_2^0\to \tildeχ_1^0 f\bar f$ and a one-loop radiative decay $\tildeχ_2^0\to \tildeχ_1^0γ$ are estimated. We investigate the condition under which the radiative decay becomes the dominant mode and also numerically search for such parameter regions. In this analysis we take account of the abelian gaugino kinetic term mixing. We suggest that the gaugino mass relation $M_W\sim M_Y$ may not be necessary for the radiative decay dominance in the extra U(1) models.

description: Transportation facilities are becoming more developed as society develops, and people's travel demand is increasing, but so are the traffic safety issues that arise as a result. And car accidents are a major issue all over the world. The cost of traffic fatalities and driver injuries has a significant impact on society. The use of machine learning techniques in the field of traffic accidents is becoming increasingly popular. Machine learning classifiers are used instead of traditional data mining techniques to produce better results and accuracy. As a result, this project conducts research on existing work related to accident prediction using machine learning. We will use crash data and weather data to train machine learning models to predict crash severity and reduce crashes.

description: Scheme independence of exact renormalization group equations, including independence of the choice of cutoff function, is shown to follow from general field redefinitions, which remains an inherent redundancy in quantum field theories. Renormalization group equations and their solutions are amenable to a simple formulation which is manifestly covariant under such a symmetry group. Notably, the kernel of the exact equations which controls the integration of modes acts as a field connection along the flow.

title: Developing Low-Density Lipoprotein Receptor-Related Protein-1 Agonists as a Therapeutic Strategy in Allergic Inflammatory Diseases

description: Allergic inflammatory diseases such as atopic dermatitis, eosinophilic esophagitis (EoE) and asthma are a consequence of persistent exposure to allergens leading to impaired innate immune mechanisms and dysregulated immune responses. A large unmet need exists for an effective treatment that is devoid of potentially serious side effects and without immunosuppressive effects. We have previously developed a family of first-in-class drugs derived from naturally occurring Serine Protease Inhibitors (SERPINS) that target Low-Density Lipoprotein Receptor-Related Protein-1 (LRP-1), a homeostatic receptor that regulates a multitude of critical functions of the immune response. The lead peptide, SP16, is a short (17mer) modified peptide derivative of Alpha-1 Antitrypsin (AAT). Recent work has shown that both AAT and LRP-1 play a role in alleviating allergen-driven inflammation. In this study, we have designed a series of SP16-derivative analogs modeled on the putative LRP-1 binding site, with the goal of developing these peptide therapeutics for inflammatory diseases. We have methodically screened these analogs for their ability to inhibit inflammation, refining the analog design based on structure-activity relationships. In three tissue specific cell lines, analogs showed increased potency, with dramatically improved effective concentrations (EC50s) compared to SP16, and no toxicity, thus having the potential for an increased therapeutic window. In-vitro, ELISA based LRP-1 binding assays showed target engagement. Lead analogs, screened in a rapid in-vivo mouse model of acute inflammation, exhibited significant anti-inflammatory function comparable to SP16. The analogs demonstrated improved pharmacokinetic properties and potential for a wider range of administration routes, including oral. Finally, a few select analogs, alongside SP16, were tested for their ability to inhibit TH2 mediated responses in mouse models of atopic dermatitis and asthma. Both SP16 and analogs showed significant amelioration of disease phenotypes, including thymic stromal lymphopoietin (TSLP) inhibition. Overall, the developmental work has defined two new lead SERPIN-derived LRP-1 agonists for inflammatory diseases and provided a new avenue of SP16 development in allergic inflammation.
Feynman's different approach to electromagnetism

description: We discuss a previously unpublished description of electromagnetism outlined by Richard P. Feynman in the 1960s in five handwritten pages, recently uncovered among his papers, and partly developed in later lectures. Though similar to the existing approaches deriving electromagnetism from special relativity, the present one extends a long way towards the derivation of Maxwell's equations with minimal physical assumptions. In particular, without postulating Coulomb's law, homogeneous Maxwell's equations are written down by following a route different from the standard one, i.e. first introducing electromagnetic potentials in order to write down a relativistic invariant action, which is just the inverse approach to the usual one. Also, Feynman's derivation of the Lorentz force exclusively follows from its linearity in the charge velocity and from relativistic invariance. Going further, i.e. adding the inhomogeneous Maxwell's equations, requires some more physical input, and can be done by just following conventional lines, hence this task was not pursued here. Despite its incompleteness, this way of proceeding is of great historical and epistemological significance. We also comment about its possible relevance to didactics, as an interesting supplement to usual treatments.

description: Making use of self-assembly techniques, we demonstrate the realization of nanoscopic semiconductor quantum rings in which the electronic states are in the true quantum limit. We employ two complementary spectroscopic techniques to investigate both the ground states and the excitations of these rings. Applying a magnetic field perpendicular to the plane of the rings, we find that when approximately one flux quantum threads the interior of each ring, a change in the ground state from angular momentum $\ell = 0$ to $\ell = -1$ takes place. This ground state transition is revealed both by a drastic modification of the excitation spectrum and by a change in the magnetic field dispersion of the single-electron charging energy.

description: The way that law enforcement interacts with residents has been at the forefront of media scrutiny. The police, or street level bureaucrats, are often the most visible representation of a community and are afforded a plethora of discretion (Lipsky, 1980). However, their exercise of said discretion, or police behavior, varies greatly from one area to another. Gaining insight into how the police conduct their business is essential to better understand their roles as law enforcement officers in a particular area. Similarly, an effective police department relies on the assistance of active residents to help secure and regulate a community (Sargeant, 2017). Compliance and cooperation of residents depends upon how satisfied they may be with their local police. The primary focus of this study is to better understand how specific individuallevel variables relating to police behavior and community are associated with satisfaction with police and their services in Roanoke County, Virginia. While prior research has focused primarily on urban or suburban settings to explore community-police relations, I quantitatively analyze survey data from a unique suburban-rural setting to better explain how contact with authorities, procedural justice, and community context (specifically, collective efficacy, perception of neighborhood conditions, and residential stability) is associated with citizen satisfaction with local police and police services. Given the current social and political climate, there is severe strain on police-community relations. However, effective communication between the police and the citizens they serve can curb resentment and increase legitimacy. This mutually beneficial partnership can help address community concerns, assess police performance, and outline future needs that should be addressed.
