title: Striving to Preserve the Peace! The National Council for Civil Liberties, the Metropolitan Police and the dynamics of disorder in Inter-War Britain
Creators: name: Clark, Janet
Publisher: name: The Open University
Year: 2008

description: This thesis re-examines the policing of political activism in 1930s London. It was a period of struggle between political extremes that provoked some of the most violent disorder on London's streets in the history of the Metropolitan Police. This thesis explores the emergence of the National Council for Civil Liberties (NCCL) and its role in the context of the policing of political disorder in the period. The early chapters consider current historiography and the background to policing policies and operational techniques that led to a view of policing as partisan and tolerant of right wing (fascist) violence. The political events and chance involvement of the press that led to the formation of the NCCL are examined together with the prominent and influential support that emerged for a civil liberties movement. It is argued that the authorities regarded the NCCL as a product of the radical left but, at the same time, the organisation attracted wide popular support for its aims and the backing of the liberal press and in parliament. Chapters five and six show that the Home Secretary became progressively more concerned about the public order policing operation in the capital as police powers and political activism increasingly became the focus of the NCCL's campaign through 1935 and 1936. In chapter seven the discussion of the implementation of the Public Order Act 1936 illustrates the resultant tensions between the Commissioner and the Home Secretary. Finally it is argued that the NCCL achieved wide recognition as an important pressure group with established influence in parliament despite the finely balanced position it occupied in the political spectrum. It is concluded that the NCCL played a much more active and influential role in the policing of political disorder in the 1930s than has previously been acknowledged and thus an important aspect of the debate has been neglected.

description: A new extended solid nitrogen, referred to post-layered-polymeric nitrogen (PLP-N), was observed by further heating the layered-polymeric nitrogen (LP-N) to above 2300 K at 161 GPa. The new phase is found to be very transparent and exhibits ultra-large d-spacings ranging from 2.8 to 4.9 Å at 172 GPa, suggesting a possible large-unit-cell 2D chain-like or 0D cluster-type structure with wide bandgap. However, the observed X-ray diffraction pattern and Raman scattering data cannot match any predicted structures in the published literature. This finding further complicates the phase diagram of nitrogen and also highlights the path dependence of the high-pressure dissociative transition in nitrogen. In addition, the forming boundary between cg-N and LP-N has been determined.

description: When the SARS genomic sequence became available early in 2003, I was able to identify 2 programmed ribosomal frameshift sites in the virus, both associated with an in-frame UGA (potential selenocysteine) codon in the overlapping reading frame. Both of these frameshift sites were later shown to be functional via in vitro reporter gene assays. Dr. Jinsong Zhang contacted me with evidence of selenium abnormalities in the blood of SARS patients, leading to the joint abstract. These results were never published at the time because the SARS outbreak was contained and with the threat no longer imminent, it was not possible to get funding to pursue the findings. The 2 frameshift sites, their in-frame UGA codons, and glutathione peroxidase homology region are also found in the 2019 SARS-CoV-2 virus, supporting a role for selenium in the pathology of COVID-19.

description: The mechanisms of dislocation/precipitate interactions were analyzed in an Al-Cu alloy containing a homogeneous dispersion of $θ'$ precipitates by means of discrete dislocation dynamics simulations. The simulations were carried out within the framework of the discrete-continuous method and the precipitates were assumed to be impenetrable by dislocations. The main parameters that determine the dislocation/precipitate interactions (elastic mismatch, stress-free transformation strains, dislocation mobility and cross-slip rate) were obtained from atomistic simulations, while the size, shape, spatial distribution and volume fraction of the precipitates were obtained from transmission electron microscopy. The predictions of the critical resolved shear stress (including the contribution of solid solution) were in agreement with the experimental results obtained by means of compression tests in micropillars of the Al-Cu alloy oriented for single slip. The simulations revealed that the most important contribution to the precipitation hardening of the alloy was provided by the stress-free transformation strains followed by the solution hardening and the Orowan mechanism due to the bow-out of the dislocations around the precipitates.

description: Recent advances in transgene design have demonstrated the use of C. reinhardtii as a photosynthetic cell chassis for sustainable heterologous production of natural products. A domesticated strain (UVM4) with high nuclear genome transgene expression capability was optimized for the capacity to grow on inorganic phosphite and nitrate as sole sources of P and N, respectively, to enable high-cell density cultivation with reduced contamination risk. This strain (UPN) serves as a platform to produce heterologous metabolites in our group. A further goal in the use of this strain was to add value to spent biomass by leveraging C. reinhardtii’s generally regarded as safe (GRAS) status to sustainably produce food-grade recombinant proteins (RPs) and high-value pigments, such as the keto-carotenoid astaxanthin. A range of proteins of interest to the food industry were selected, coding sequences optimized for chloroplast expression, and given strep-II tags for Western blot detection / down-stream purification. The chloroplast of UPN was engineered to encode these RPs by PsbH knock-out/ restoration transformation to enable antibiotic-free selection. Transformants with successful chloroplast RP expression were further engineered to express to ß-carotene hydroxylase (CrCHYB) and ß-carotene ketolase (CrBKT) from the nuclear genome to produce astaxanthin. Further work is required to quantify the levels of astaxanthin production and to examine of the effect of chloroplast accumulation of keto-carotenoids on the expression/yield of chloroplast genome encoded RP. Further screening of transformants with different chloroplast genome expressed RPs and high astaxanthin production is required find an economically attractive product compatible with other metabolic engineering projects in the SSB group.

Deklamationen waren im antiken Rom Übungs- und Konzertreden und bildeten Gegenstand und Ziel der höheren Bildung. Dass sie im heutigen Lateinunterricht und auch im Lateinstudium kaum behandelt werden, steht in einem deutlichen Missverhältnis zu ihrer damaligen Bedeutung. Diese Lücke zu schließen ist das Anliegen der vorliegenden Masterarbeit mit dem darin enthaltenen Schülermaterial. Bei dessen Bearbeitung werden die Schüler die thematische Vielfalt der Deklamationen kennenlernen, aber auch bemerkenswerte Parallelen zum gegenwärtigen Populismus feststellen und das Macht- und Verführungspotential von Rhetorik selbst erfahren. Das Material wurde auf der Basis der aktuellen fachwissenschaftlichen Diskussion erstellt. Der Anhang enthält zwei tabellarische Übersichten zu den Deklamationsthemen. Diese sind für eigene Fortentwicklungen der Reihe gedacht.

description: We aimed to describe the clinical efficacy and safety of tislelizumab, a new (PD-1) inhibitor, in patients with malignant solid tumors. We searched relevant databases for phase III randomized controlled trials, including patients with solid tumors. The following outcomes are of interest: overall response rate (OS), overall survival (ORR), progression-free survival (PFS), disease control rate (DCR), and treatment-related adverse events (TRAE). We conducted subgroup analyses based on the line of therapy, type of solid tumor, and tislelizumab alone or combined with chemotherapy. Seven phase III RCTs with 3478 were included in the meta-analysis. Pooled analysis demonstrated that tislelizumab significantly improved ORR and DCR with (OR) of 2.59 (95% (CI) = 2.15–3.12, p < 0.00001) and 1.78 (95% CI = 1.43–2.21, p > 0.00001), respectively. Pooled HRs for OS and PFS were 0.71 (95% CI = 0.65-0.78, p > 0.00001) and 0.68 (95% CI = 0.54–0.84, p = 0.0005), respectively. Overall, based on this meta-analysis, the available data strongly supports the utilization of tislelizumab in the treatment of malignant solid tumors. CRD42023408815

description: Graph clustering has been studied extensively on both plain graphs and attributed graphs. However, all these methods need to partition the whole graph to find cluster structures. Sometimes, based on domain knowledge, people may have information about a specific target region in the graph and only want to find a single cluster concentrated on this local region. Such a task is called local clustering. In contrast to global clustering, local clustering aims to find only one cluster that is concentrating on the given seed vertex (and also on the designated attributes for attributed graphs). Currently, very few methods can deal with this kind of task. To this end, we propose two quality measures for a local cluster: Graph Unimodality (GU) and Attribute Unimodality (AU). The former measures the homogeneity of the graph structure while the latter measures the homogeneity of the subspace that is composed of the designated attributes. We call their linear combination as Compactness. Further, we propose LOCLU to optimize the Compactness score. The local cluster detected by LOCLU concentrates on the region of interest, provides efficient information flow in the graph and exhibits a unimodal data distribution in the subspace of the designated attributes.
On the (anisotropic) uniform metallic ground states of fermions interacting through arbitrary two-body potentials in d dimensions

description: We demonstrate that the skeleton of the Fermi surface S_{F;s} pertaining to a uniform metallic ground state (corresponding to fermions with spin index s) is determined by the Hartree-Fock contribution to the dynamic self-energy. The Fermi surface S_{F;s} consists of all points which in addition to satisfying the quasi-particle equation in terms of the Hartree-Fock self-energy, fulfill the equation S_{s}(k) = 0, where S_{s}(k) is defined in the main text; the set of k points which satisfy the Hartree-Fock quasi-particle equation but fail to satisfy S_{s}(k) = 0, constitute the pseudo-gap region of the putative Fermi surface of the interacting system. We consider the behaviour of the ground-state momentum-distribution function n_{s}(k) for k in the vicinity of S_{F;s} and show that whereas for the uniform metallic ground states of the conventional Hubbard Hamiltonian n_{s}(k) is greater/less than 0.5 for k approaching S_{F;s} from inside/outside the Fermi sea, for interactions of non-zero range these inequalities can be violated (without thereby contravening the condition of the non-negativity of the possible jump in n_{s}(k) on k crossing S_{F;s} from directly inside to directly outside the Fermi sea). We discuss, in the light of the findings of the present work, the growing experimental evidence with regard to the `frustration' of the kinetic energy of the charge carriers in the normal states of the copper-oxide-based high-temperature superconducting compounds.

We allow for a variety of extensions, including the role of (marginal) cost savings, remedies (divestiture), and conduct different from Bertrand–Nash behavior.
title: The role of proteasome dysfunction in the mechanisms of motor neuron degeneration in a mouse model of familial amyotrophic lateral sclerosis
Creators: name: Cheroni, Cristina
Publisher: name: The Open University
Year: 2008

description: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by the loss of the motor neurons. One consistent neuropathological feature of ALS patients and models of the disease is the formation of proteinaceous inclusion bodies; for this reason, alterations in the proteolytic ubiquitin-proteasome pathway (UPP) have been suggested to be implicated.

The purpose of this thesis was to analyze the role of the UPP in ALS pathogenesis studying the G93A mouse model. The activity of UPP was evaluated in G93A mice carrying the UbG76V-GFP reporter protein for proteasomal functionality. Furthermore, the expression of different constitutive proteasome and immunoproteasome subunits was measured during disease progression.

In symptomatic G93A lumbar spinal cord, a mild increase of UbG76V-GFP protein, but not of its transcript, was found in the motor neuronal population and was partly associated with high levels of ubiquitin and perikarial presence of phosphorylated neurofilaments. At the end stage, the increase of the reporter protein was prevalent in other neurons besides motor neurons, but also the mRNA levels were augmented.

Constitutive catalytic subunits of the 20S proteasome were reduced in end stage G93A lumbar spinal cord, while an increase of their inducible counterparts and a decrease of the non-catalytic as subunit were evident at the symptomatic phase. Components of 19S and 11S complexes were significantly reduced prior to symptom onset. The changes in proteasome composition were accompanied by a substantial increase of glial markers and TNFα.

Altogether, these data suggest that a subtle dysfunction of the ubiquitin-proteasome pathway occurs in the spinal cord of a mouse model of ALS in a phase in which the first signs of motor impairment are detectable. This pairs with alterations in the transcriptional rate of various proteasome subunits, resulting in a decrease of constitutive proteasome and an increase of immunoproteasome.

description: Virtually all electronic systems try to optimize a fundamental trade-off between higher performance and lower power consumption. The latter becomes critical in mobile computing systems, such as smartphones, which rely on passive cooling. Otherwise, the heat concentrated in a small area drives both the junction and skin temperatures up. High junction temperatures degrade the reliability, while skin temperature deteriorates the user experience. Therefore, there is a strong need for a formal analysis of power consumption-temperature dynamics and predictive thermal management algorithms. This paper presents a theoretical power-temperature analysis of multiprocessor systems, which are modeled as multi-input multi-output dynamic systems. We analyze the conditions under which the system converges to a stable steady-state temperature. Then, we use these models to design a control algorithm that manages the temperature of the system without affecting the performance of the application. Experiments on the Odroid-XU3 board show that the control algorithm is able to regulate the temperature with a minimal loss in performance when compared to the default thermal governors.

description: A new method for the analysis of time to ankylosis complication on a dataset of replanted teeth is proposed. In this context of left-censored, interval-censored and right-censored data, a Cox model with piecewise constant baseline hazard is introduced. Estimation is carried out with the expectation maximisation (EM) algorithm by treating the true event times as unobserved variables. This estimation procedure is shown to produce a block diagonal Hessian matrix of the baseline parameters. Taking advantage of this interesting feature in the EM algorithm, a L0 penalised likelihood method is implemented in order to automatically determine the number and locations of the cuts of the baseline hazard. This procedure allows to detect specific areas of time where patients are at greater risks for ankylosis. The method can be directly extended to the inclusion of exact observations and to a cure fraction. Theoretical results are obtained which allow to derive statistical inference of the model parameters from asymptotic likelihood theory. Through simulation studies, the penalisation technique is shown to provide a good fit of the baseline hazard and precise estimations of the resulting regression parameters.

description: Reweighting is a popular statistical technique to deal with inference in the presence of a nonrandom sample, and various reweighting estimators have been proposed in the literature. This article presents the user-written command treatrew, which implements reweighting on the propensity-score estimator as proposed by Rosenbaum and Rubin (1983, Biometrika 70: 41–55) in their seminal article. The main contribution of this command lies in providing analytical standard errors for the average treatment effects in the whole population, in the subpopulation of the treated, and in that of the untreated. Standard errors are calculated using the approximation suggested by Wooldridge (2010, 920–930, Econometric Analysis of Cross Section and Panel Data [MIT Press]), but bootstrapped standard errors can also be easily computed. Because an implementation of this estimator with analytic standard errors and nonnormalized weights is missing in Stata, this article and the accompanying ado-file aim to provide the community with an easy-to-use method for reweighting on the propensity-score. The estimator proves to be a valuable tool for estimating average treatment effects under selection on observables.

description: We propose a new class of non-factorising D-branes in the product group GxG where the fluxes and metrics on the two factors do not necessarily coincide. They generalise the maximally symmetric permutation branes which are known to exist when the fluxes agree, but break the symmetry down to the diagonal current algebra in the generic case. Evidence for the existence of these branes comes from a Lagrangian description for the open string world-sheet and from effective Dirac-Born-Infeld theory. We state the geometry, gauge fields and, in the case of SU(2)xSU(2), tensions and partial results on the open string spectrum. In the latter case the generalised permutation branes provide a natural and complete explanation for the charges predicted by K-theory including their torsion.

Highly Efficient Porous FexCe1–xO2−δ with Three-Dimensional Hierarchical Nanoflower Morphology for H2S-Selective Oxidation
Creators: name: Zheng, Xiaohai
Publisher: name: figshare
Year: 2020
Subjects: Environmental Chemistry

description: CeO2-based catalysts are potentially suitable for H2S selective oxidation, but their practical application is limited due to the problem of sulfate formation. Herein, we report a facile citric acid-assisted hydrothermal process for the fabrication of porous Fe-doped CeO2 with flower-like morphology that can drastically promote the catalytic activities of CeO2 with high durability. Among the synthesized catalysts, the one with well-defined (110) and (100) planes is highly active for H2S selective oxidation with H2S conversion and sulfur selectivity of almost 100% at 220 °C, superior to most of the reported Ce-based catalysts. Meanwhile, outstanding catalytic stability is achieved because the presence of Fe ions alleviates ceria deactivation due to sulfation. The results of systematic investigation prove that the doping of Fe not only raises the density of oxygen vacancies, but also promotes the redox ability and oxygen activity of the catalyst. We conducted in situ DRIFTS experiments and density functional theory (DFT) calculations to disclose the reaction mechanism of H2S oxidation. The derived insights are important for the design of efficient ceria-related catalysts for practical applications.

description: In many observational studies, the treatment may not be binary or categorical but rather continuous, so the focus is on estimating a continuous dose–response function. In this article, we propose a set of programs that semiparametrically estimate the dose–response function of a continuous treatment under the unconfoundedness assumption. We focus on kernel methods and penalized spline models and use generalized propensity-score methods under continuous treatment regimes for covariate adjustment. Our programs use generalized linear models to estimate the generalized propensity score, allowing users to choose between alternative parametric assumptions. They also allow users to impose a common support condition and evaluate the balance of the covariates using various approaches. We illustrate our routines by estimating the effect of the prize amount on subsequent labor earnings for Massachusetts lottery winners, using data collected by Imbens, Rubin, and Sacerdote (2001, American Economic Review, 778–794).
A Relativistic Disk in Sagittarius A*

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The detection of a mm/Sub-mm ``bump'' in Sgr A*'s radio spectrum suggests that at least a portion of its overall emission is produced within a compact accretion torus. This inference is strengthened by observations of strong linear polarization (at the 10 percent level) within this bump. No linear polarization has been detected yet at other wavelengths. Given that radiation from this source is produced on progressively smaller spatial scales with increasing frequency, the mm/Sub-mm bump apparently arises within a mere handful of Schwarzschild radii of the black hole. We have found that a small (10-Schwarzschild-radii) magnetized accretion torus can not only account for the spectral bump via thermal synchrotron processes, but that it can also reproduce the corresponding polarimetric results. In addition, the quiescent X-ray emission appears to be associated with synchrotron self-Comptonization, while X-ray flares detected from Sgr A* may be induced by a sudden enhancement of accretion through this torus. This picture predicts correlations among the mm, IR, and X-ray flux densities, that appear to be consistent with recent multi-wavelength observations. Further evidence for such a torus in Sgr A* is provided by its radio variability. Recent monitoring of Sgr A* at cm and mm wavelengths suggests for a spectral break at 3 mm during cm/Sub-mm flares. Radio emission from Sgr A* is intriguing since it is circularly polarized though no linear polarization was ever detected. We first proved that the emission must be due to nonthermal process should the flow be bounded. It is then suggested that the nonthermal electrons are energized very close to the black hole.

description: While exoplanets are now routinely detected, the detection of small bodies in extrasolar systems remains challenging. Since the discovery of sporadic events interpreted as exocomets (Falling Evaporating Bodies) around $β$ Pic in the early 80s, only $\sim$20 stars have been reported to host exocomet-like events. We aim to expand the sample of known exocomet-host stars, as well as to monitor the hot-gas environment around stars with previously known exocometary activity. We have obtained high-resolution optical spectra of a heterogeneous sample of 117 main-sequence stars in the spectral type range from B8 to G8. The data have been collected in 14 observing campaigns expanding over 2 years from both hemispheres. We have analysed the Ca ii K&H and Na i D lines in order to search for non-photospheric absorptions originated in the circumstellar environment, and for variable events that could be caused by outgassing of exocomet-like bodies. We have detected non-photospheric absorptions towards 50% of the sample, attributing a circumstellar origin to half of the detections (i.e. 26% of the sample). Hot circumstellar gas is detected in the metallic lines inspected via narrow stable absorptions, and/or variable blue-/red-shifted absorption events. Such variable events were found in 18 stars in the Ca ii and/or Na i lines; 6 of them are reported in the context of this work for the first time. In some cases the variations we report in the Ca ii K line are similar to those observed in $β$ Pic. While we do not find a significant trend with the age or location of the stars, we do find that the probability of finding CS gas in stars with larger vsin i is higher. We also find a weak trend with the presence of near-infrared excess, and with anomalous ($λ$ Boo-like) abundances, but this would require confirmation by expanding the sample.

title: Arguing Security: A Framework for Analyzing Security Requirements
Creators: name: Haley, Charles B.
Publisher: name: The Open University
Year: 2007

description: When considering the security of a system, the analyst must simultaneously work with two types of properties: those that can be shown to be true, and those that must be argued as being true. The first consists of properties that can be demonstrated conclusively, such as the type of encryption in use or the existence of an authentication scheme. The second consists of things that cannot be so demonstrated but must be considered true for a system to be secure, such as the trustworthiness of a public key infrastructure or the willingness of people to keep their passwords secure. The choices represented by the second case are called trust assumptions, and the analyst should supply arguments explaining why the trust assumptions are valid. This thesis presents three novel contributions: a framework for security requirements elicitation and analysis, based upon the construction of a context for the system; an explicit place and role for trust assumptions in security requirements; and structured satisfaction arguments to validate that a system can satisfy the security requirements. The system context is described using a problem-centered notation, then is validated against the security requirements through construction of a satisfaction argument. The satisfaction argument is in two parts: a formal argument that the system can meet its security requirements, and structured informal arguments supporting the assumptions exposed during argument construction. If one cannot construct a convincing argument, designers are asked to provide design information to resolve the problems and another pass is made through the framework to verify that the proposed solution satisfies the requirements. Alternatively, stakeholders are asked to modify the goals for the system so that the problems can be resolved or avoided. The contributions are evaluated by using the framework to do a security requirements analysis within an air traffic control technology evaluation project.

description: We establish a link between the study of completely integrable systems of partial differential equations and the study of generic submanifolds in C^n. Using the recent developments of Cauchy-Riemann geometry we provide the set of symmetries of such a system with a Lie group structure. Finally we determine the precise upper bound of the dimension of this Lie group for some specific systems of partial differential equations.

description: I describe algorithms for drawing from distributions using adaptive Markov chain Monte Carlo (MCMC) methods; I introduce a Mata function for performing adaptive MCMC, amcmc(); and I present a suite of functions, amcmc_*(), that allows an alternative implementation of adaptive MCMC. amcmc() and amcmc_*() can be used with models set up to work with Mata's moptimize() (see [M-5] moptimize()) or optimize() (see [M-5] optimize()) or with standalone functions. To show how the routines can be used in estimation problems, I give two examples of what Chernozhukov and Hong (2003, Journal of Econometrics 115: 293–346) refer to as quasi-Bayesian or Laplace-type estimators—simulationbased estimators using MCMC sampling. In the first example, I illustrate basic ideas and show how a simple linear model can be fit by simulation. In the next example, I describe simulation-based estimation of a censored quantile regression model following Powell (1986, Journal of Econometrics 32: 143–155); the discussion describes the workings of the command mcmccqreg. I also present an example of how the routines can be used to draw from distributions without a normalizing constant and used in Bayesian estimation of a mixed logit model. This discussion introduces the command bayesmixedlogit.

description: Athletes trying to gain muscle mass must carefully watch their diets, monitoring their macronutrient and caloric intake. Continued muscle development for many can be constrained by income, obstructing their ability to afford a diet high in protein. There are many affordable protein options, but it is unrealistic to consume only one food as the taste of each food must also be taken into account. A diet optimization model is presented that optimizes cost, taste, and nutritional values while achieving appropriate protein, calorie, fat, and carbohydrate levels. Two different body types are considered of both a runner and a body builder, and two different optimization methods are compared.
JLab: Probing Hadronic Physics with Electrons and Photons

description: Precision measurements of the structure of nucleons and nuclei in the regime of strong interaction QCD are now possible with the availability of high current polarized electron beams, polarized targets, and recoil polarimeters, in conjunction with modern spectrometers and detector instrumentation. The physics at JLab will be highlighted using two recent measurements of general interest. The ratio of the proton electric to magnetic form factors indicates the importance of the role of angular momentum in the structure of the nucleon. The existence of 5-quark configurations in the ground state wavefunctions of hadrons is confirmed by a narrow peak attributed to an exotic baryon with strangeness S=+1. These and other examples will be used to illustrate the capabilities and focus of the experimental program at JLab.

description: The optical properties of LXe in the vacuum ultra violet (VUV), determining the performance of a scintillation calorimeter, are discussed in detail. The available data, measured in a wider spectral region from visible to UV light, and in a large range of Xe densities, from gas to liquid, are examined. It is shown that this information can be used for deriving the LXe optical properties in the VUV. A comparison is made with the few direct measurements in LXe for VUV light resulting from the LXe excitation by ionizing particles. A useful relation is obtained which connects the Rayleigh scattering length to the refractive index in LXe.

description: The one dimensional dilute Kondo lattice model is investigated by means of bosonization for different dilution patterns of the array of impurity spins. The physical picture is very different if a commensurate or incommensurate doping of the impurity spins is considered. For the commensurate case, the obtained phase diagram is verified using a non-Abelian density-matrix renormalization-group algorithm. The paramagnetic phase widens at the expense of the ferromagnetic phase as the $f$-spins are diluted. For the incommensurate case, antiferromagnetism is found at low doping, which distinguishes the dilute Kondo lattice model from the standard Kondo lattice model.
