description: We report measurements of the magnetoresistance in the charge density wave (CDW) state of rare-earth tritellurides, namely TbTe$_3$ and HoTe$_3$. The magnetic field dependence of magnetoresistance exhibits a temperature dependent crossover between a conventional quadratic law at high $T$ and low $B$ and an unusual linear dependence at low $T$ and high $B$. We present a quite general model to explain the linear magnetoresistance taking into account the strong scattering of quasiparticles on CDW fluctuations in the vicinity of "hot spots" of the Fermi surface (FS) where the FS reconstruction is the strongest.

Qualitative Insights on Diverse Impacts of Interprofessional Relationships in Nursing Homes
Creators: name: Kim, Mhinjine
Publisher: name: University of Illinois at Chicago
Year: 2024

description: Background: Preventable nursing home (NH) resident hospitalization remains a critical public health issue. Studies found that improved interprofessional relationships may help reduce preventable resident hospitalizations, yet there is limited research on how different traits of relationships and communication may affect hospitalization decisions. Moreover, understanding perceived changes of work practices and interprofessional relationships of NH nurses due to COVID-19 may help to address future health emergencies. In this thesis, two exploratory, descriptive qualitative studies were conducted to understand NH nurses’ perspectives on: (1) perceived relationship between the different characteristics of interprofessional relationships and resident outcomes and (2) perceived impact of the COVID-19 pandemic on NH nurses’ work and interprofessional relationships. Methods: In the first study, two focus group (FG) sessions were conducted with 14 nurses (N=9, N=5) in June and December 2018 in two Chicagoland NHs. Three FGs were conducted in two Chicagoland NHs in the second study (one in June 2022 with nurses (N=10) in facility 1 and the second in October 2022 with nurses (N=3, N=2) in facility 2). All focus group sessions were transcribed, coded, and analyzed for shared themes and topics with the qualitative description method. Results: In the first study, nurse participants described their roles to be important in hospitalization decisions, yet perceived level of influence varied by the individual characteristics of other providers. Such perceived differences in roles, quality and pattern of communication, and use of emotions may affect nurse-provider relationships, which may also influence preventable resident hospitalizations. In the second study, nurses mentioned heavier workloads from the COVID-19 pandemic (e.g., infection control). Although participants’ interprofessional relationships and communication with other providers and nurses were found not to be negatively affected by the pandemic, some perceived challenges in interprofessional interactions with the NH administrators and leadership. Conclusions: Interprofessional factors may influence NH hospitalization decisions and preventable hospitalizations of NH residents may be more effectively reduced when these factors are targeted. During the COVID-19 pandemic, NH nurses perceived different work challenges, and mentioned positive and negative changes in their interprofessional relationships with different NH staff members (e.g., other providers and nurses versus NH administrators).

description: A caracterização da bradicinesia parkinsoniana tem sido foco de vários trabalhos e a maioria desses estudos utiliza escalas subjetivas para a sua avaliação. Recentemente, algumas pesquisas têm proposto a avaliação da bradicinesia por meio de sensores inerciais e eletromiográficos. Uma das principais dificuldades na realização desses estudos é relacionada à identificação de parâmetros extraídos dos sinais mensurados, que possibilitem a caracterização de padrões de normalidade e bradicinesia. Neste sentido, essa pesquisa investigou o padrão de oito parâmetros temporais e inerciais, com a finalidade de caracterizar grupos de indivíduos hígidos e com a doença de Parkinson, sendo esses, cinco temporais –tempo para atingir a máxima velocidade angular (TVangMax), aceleração linear (TAccMax), variação do campo magnético (TMagMax), contração muscular (TEMGMax) e o tempo total de execução da tarefa (TTASK); e três inerciais - velocidade angular máxima (VAngMax), aceleração máxima (AccMax) e variação de campo magnético máxima (MagMax).No total 27 indivíduos participaram do estudo, sendo 12 hígidos (60,1 ±6,1 anos) e 15 com a doença de Parkinson (65,3 ±9,1 anos). A severidade da bradicinesia dos indivíduos com a doença de Parkinson foi avaliada pelo neurologista com base na escala UPDRS.Todos os indivíduos executaram o movimento de extensão de punho com o antebraço apoiado. Os movimentos foram executados com e sem a presença de uma carga de 92 gramas. A avaliação comparativa entre os parâmetros estimados para cada grupo baseou-se na aplicação do teste Wilcoxon com p < 0.05. Os resultados do estudo mostraram que a carga utilizada não influenciou os parâmetros estimados de nenhum dos grupos. Eles ainda demonstraram que todos os parâmetros estimados, com exceção do MagMax, possibilitaram a discriminação entre os grupos. Esses achados são relevantes para estudos clínicos que necessitam de parâmetros objetivos para a avaliação e monitoramento da eficácia de terapias relacionadas ao controle da bradicinesia parkinsoniana.

description: Despite recent initiatives to promote water conservation throughout campus, we are still a long way from reaching the sustainability goals advertised in the UCLA Zero Waste 2020 Initiative. Architects and plumbing experts have recently developed rainwater systems and low-flow restroom facilities as eco-friendly alternatives to conventional toilet flushing, yet these amenities are still continuously overlooked by the general public. In order to create sustainable, long-lasting changes in current restroom facilities, we will first quantify the university’s water consumption and identify any environmental or human factors that have contributed to this current trend of excess. This project successfully audited the restroom fixtures of three main buildings on the UCLA campus (Powell Library, the John Wooden Center, and Murphy Hall). Although data collection was not fully ascertained in Powell Library and the John Wooden Center due to environmental factors and related complications, the results reveal extensive water usage in Murphy Hall compared to the other buildings. Given this, we will offer recommendations for the Office for Sustainability at UCLA to promote better water conservation management practices, as well as propose a new water saving and tracking system similar to what is currently in place on other UC campuses.

description: In this paper, we present a software compilation approach for microprocessor/FPGA platforms that partitions a software binary onto custom hardware implemented in the FPGA. Our approach imposes less restrictions on software tool flow than previous compiler approaches, allowing software designers to use any software language and compiler. Our approach uses a back-end partitioning tool that utilizes decompilation techniques to recover important high-level information, resulting in performance comparable to high-level compiler-based approaches.

description: We examine a network of learners which address the same classification task but must learn from different data sets. The learners cannot share data but instead share their models. Models are shared only one time so as to preserve the network load. We introduce DELCO (standing for Decentralized Ensemble Learning with COpulas), a new approach allowing to aggregate the predictions of the classifiers trained by each learner. The proposed method aggregates the base classifiers using a probabilistic model relying on Gaussian copulas. Experiments on logistic regressor ensembles demonstrate competing accuracy and increased robustness in case of dependent classifiers.

description: We present a Bayesian Voronoi image reconstruction technique (VIR) for interferometric data. Bayesian analysis applied to the inverse problem allows us to derive the a-posteriori probability of a novel parameterization of interferometric images. We use a variable Voronoi diagram as our model in place of the usual fixed pixel grid. A quantization of the intensity field allows us to calculate the likelihood function and a-priori probabilities. The Voronoi image is optimized including the number of polygons as free parameters. We apply our algorithm to deconvolve simulated interferometric data. Residuals, restored images and chi^2 values are used to compare our reconstructions with fixed grid models. VIR has the advantage of modeling the image with few parameters, obtaining a better image from a Bayesian point of view.

description: We believe that future large-scale multicore systems will require disciplined parallel programming practices, including data-race-freedom, deterministic-by-default semantics, and structured, explicit parallel control and side-effects. We argue that this software evolution presents far-reaching opportunities for parallel hardware design to greatly improve complexity, power-efficiency, and performance scalability. The DeNovo project is rethinking hardware design from the ground up to exploit these opportunities. This paper presents the broad research agenda of DeNovo, including a holistic rethinking of cache coherence, memory consistency, communication, and cache architecture.

description: This paper presents a scheme for efficient channel usage between simulator and accelerator where the accelerator models some RTL sub-blocks in the accelerator-based hardware/software co-simulation while the simulator runs transaction-level model of the remaining part of the whole chip being verified. With conventional simulation accelerator, evaluations of simulator and accelerator alternate at every valid simulation time, which results in poor simulation performance due to startup overhead of simulator-accelerator channel access. The startup overhead can be reduced by merging multiple transactions on the channel into a single burst traffic. We propose a predictive packetizing scheme for reducing channel traffic by merging as many transactions into a burst traffic as possible based on 'prediction and rollback.' Under ideal condition with 100% prediction accuracy, the proposed method shows a performance gain of 1500% compared to the conventional one.

description: We discuss a time-harmonic inverse scattering problem for the Helmholtz equation with compactly supported penetrable and possibly inhomogeneous scattering objects in an unbounded homogeneous background medium, and we develop a monotonicity relation for the far field operator that maps superpositions of incident plane waves to the far field patterns of the corresponding scattered waves. We utilize this monotonicity relation to establish novel characterizations of the support of the scattering objects in terms of the far field operator. These are related to and extend corresponding results known from factorization and linear sampling methods to determine the support of unknown scattering objects from far field observations of scattered fields. An attraction of the new characterizations is that they only require the refractive index of the scattering objects to be above or below the refractive index of the background medium locally and near the boundary of the scatterers. An important tool to prove these results are so-called localized wave functions that have arbitrarily large norm in some prescribed region while at the same time having arbitrarily small norm in some other prescribed region. We present numerical examples to illustrate our theoretical findings.

description: Many scientific and industrial processes produce data that is best analysed as vectors of relative values, often called compositions or proportions. The Dirichlet distribution is a natural distribution to use for composition or proportion data. It has the advantage of a low number of parameters, making it the parsimonious choice in many cases. In this paper we consider the case where the outcome of a process is Dirichlet, dependent on one or more explanatory variables in a regression setting. We explore some existing approaches to this problem, and then introduce a new simulation approach to fitting such models, based on the Bayesian framework. We illustrate the advantages of the new approach through simulated examples and an application in sport science. These advantages include: increased accuracy of fit, increased power for inference, and the ability to introduce random effects without additional complexity in the analysis.

A Case Study of K-8 Mathematics Teachers’ Agency and Learning within a Research-Practice Partnership
Creators: name: Han, Ahreum
Publisher: name: University of Illinois at Chicago
Year: 2024

description: This dissertation study examines K-8 mathematics teacher agency and learning within a research-practice partnership (RPP) context. The study is framed by three primary research questions: (a) How is teacher agency enacted within an RPP? (b) What do teachers perceive they are learning from their participation in an RPP? and (c) How is teacher agency connected to teacher learning in an RPP context? An ecological framework for teacher agency and situated learning theory about teacher learning were both utilized to frame the questions and analyses. Furthermore, case study methodology was employed to closely examine K-8 mathematics teachers’ participation and experience in a co-design team in one school district. Multiple types of data were collected including semi-structured interviews, meeting observations, and related documents for two years. Additionally, those data sources were supplemented with a targeted set of semi-structured interviews about teacher agency and teacher learning. The data were analyzed using primarily qualitative methods, and specifically, with coding approaches associated with grounded theory. The study’s findings indicate that the quality of teacher agency enactment changed over time, and there are multiple factors that potentially impacted their participation. Amid the teachers’ involvement in the RPP, teacher learning occurred not just about mathematics teaching but also about other areas such as leadership, collaborative abilities, and understanding of the iterative process of designing teacher support, which are all crucial components of capacity building for creating sustainable learning opportunities even after the partnership with the university. Possible connections between teacher agency and learning are discussed, and implications for inviting teachers to the RPP are offered.

description: Creation of scalar massless particles in two-dimensional Minkowski space-time--as predicted by the dynamical Casimir effect--is studied for the case of a semitransparent mirror initially at rest, then accelerating for some finite time, along a trajectory that simulates a black hole collapse (defined by Walker, and Carlitz and Willey), and finally moving with constant velocity. When the reflection and transmission coefficients are those in the model proposed by Barton, Calogeracos, and Nicolaevici [$r(w)=-iα/(\w+iα)$ and $s(w)=\w/(\w+iα)$, with $α\geq 0$], the Bogoliubov coefficients on the back side of the mirror can be computed exactly. This allows us to prove that, when $α$ is very large (case of an ideal, perfectly reflecting mirror) a thermal emission of scalar massless particles obeying Bose-Einstein statistics is radiated from the mirror (a black body radiation), in accordance with results previously obtained in the literature. However, when $α$ is finite (semitransparent mirror, a physically realistic situation) the striking result is obtained that the thermal emission of scalar massless particles obeys Fermi-Dirac statistics. We also show here that the reverse change of statistics takes place in a bidimensional fermionic model for massless particles, namely that the Fermi-Dirac statistics for the completely reflecting situation will turn into the Bose-Einstein statistics for a partially reflecting, physical mirror.

description: We consider covariance parameter estimation for a Gaussian process under inequality constraints (boundedness, monotonicity or convexity) in fixed-domain asymptotics. We address the estimation of the variance parameter and the estimation of the microergodic parameter of the Matérn and Wendland covariance functions. First, we show that the (unconstrained) maximum likelihood estimator has the same asymptotic distribution, unconditionally and conditionally to the fact that the Gaussian process satisfies the inequality constraints. Then, we study the recently suggested constrained maximum likelihood estimator. We show that it has the same asymptotic distribution as the (unconstrained) maximum likelihood estimator. In addition, we show in simulations that the constrained maximum likelihood estimator is generally more accurate on finite samples. Finally, we provide extensions to prediction and to noisy observations.
A Register Allocation Algorithm in the Presence of Scalar Replacement for Fine-Grain Configurable Architectures

description: The aggressive application of scalar replacement to array references substantially reduces the number of memory operations at the expense of a possibly very large number of registers. In this paper we describe a register allocation algorithm that assigns registers to scalar replaced array references along the critical paths of a computation, in many cases exploiting the opportunity for concurrent memory accesses. Experimental results, for a set of image/signal processing code kernels, reveal that the proposed algorithm leads to a substantial reduction of the number of execution cycles for the corresponding hardware implementation on a contemporary Field-Programmable-Gate-Array (FPGA) when compared to other greedy allocation algorithms, in some cases, using even fewer number of registers.

A Way Memoization Technique for Reducing Power Consumption of Caches in Application Specific Integrated Processors

Year: 2007
Subjects: subject: Hardware Architecture (cs.AR)

description: This paper presents a technique for eliminating redundant cache-tag and cache-way accesses to reduce power consumption. The basic idea is to keep a small number of Most Recently Used (MRU) addresses in a Memory Address Buffer (MAB) and to omit redundant tag and way accesses when there is a MAB-hit. Since the approach keeps only tag and set-index values in the MAB, the energy and area overheads are relatively small even for a MAB with a large number of entries. Furthermore, the approach does not sacrifice the performance. In other words, neither the cycle time nor the number of executed cycles increases. The proposed technique has been applied to Fujitsu VLIW processor (FR-V) and its power saving has been estimated using NanoSim. Experiments for 32kB 2-way set associative caches show the power consumption of I-cache and D-cache can be reduced by 40% and 50%, respectively.

description: We consider the cosmological symmetry reduction of the Plebanski action as a toy-model to explore, in this simple framework, some issues related to loop quantum gravity and spin-foam models. We make the classical analysis of the model and perform both path integral and canonical quantizations. As for the full theory, the reduced model admits two types of classical solutions: topological and gravitational ones. The quantization mixes these two solutions, which prevents the model to be equivalent to standard quantum cosmology. Furthermore, the topological solution dominates at the classical limit. We also study the effect of an Immirzi parameter in the model.

description: Phishing emails are semantic attacks that con people into divulging sensitive information using techniques to make the user believe that information is being requested by a legitimate source. In order to develop tools that will be effective in combating these schemes, we first must know how and why people fall for them. This study reports preliminary analysis of interviews with 20 nonexpert computer users to reveal their strategies and understand their decisions when encountering possibly suspicious emails. One of the reasons that people may be vulnerable to phishing schemes is that awareness of the risks is not linked to perceived vulnerability or to useful strategies in identifying phishing emails. Rather, our data suggest that people can manage the risks that they are most familiar with, but don’t appear to extrapolate to be wary of unfamiliar risks. We explore several strategies that people use, with varying degrees of success, in evaluating emails and in making sense of warnings offered by browsers attempting to help users navigate the web.

description: Coarse-grained reconfigurable architectures aim to achieve both goals of high performance and flexibility. However, existing reconfigurable array architectures require many resources without considering the specific application domain. Functional resources that take long latency and/or large area can be pipelined and/or shared among the processing elements. Therefore the hardware cost and the delay can be effectively reduced without any performance degradation for some application domains. We suggest such reconfigurable array architecture template and design space exploration flow for domain-specific optimization. Experimental results show that our approach is much more efficient both in performance and area compared to existing reconfigurable architectures.

description: In N=4 super Yang-Mills spin chain, we compute reflection amplitudes of magnon bound-state off giant graviton. We first compute the reflection amplitude off Y=0 brane boundary and compare it with the scattering amplitude between two magnon bound-states in the bulk. We find that analytic structure of the two amplitudes are intimately related each other: the boundary reflection amplitude is a square-root of the bulk scattering amplitude. Using such relation as a guide and taking known results at weak and strong coupling limits as inputs, we find the reflection amplitude of an elementary magnon off Z=0 giant graviton boundary. The reflection phase factor is shown to solve crossing and unitarity relations. We then compute the reflection amplitude of magnon bound-state off the Z=0 brane boundary and observe that its analytic structures are again intimately related to the bulk scattering and the Y=0 boundary reflection amplitudes. We also take dyonic giant magnon limit of these reflection amplitudes and confirm that their phase-shifts agree completely with string worldsheet computations based on complex sine-Gordon soliton scattering.

description: Field programmable gate arrays (FPGAs) provide designers with the ability to quickly create hardware circuits. Increases in FPGA configurable logic capacity and decreasing FPGA costs have enabled designers to more readily incorporate FPGAs in their designs. FPGA vendors have begun providing configurable soft processor cores that can be synthesized onto their FPGA products. While FPGAs with soft processor cores provide designers with increased flexibility, such processors typically have degraded performance and energy consumption compared to hard-core processors. Previously, we proposed warp processing, a technique capable of optimizing a software application by dynamically and transparently re-implementing critical software kernels as custom circuits in on-chip configurable logic. In this paper, we study the potential of a MicroBlaze soft-core based warp processing system to eliminate the performance and energy overhead of a soft-core processor compared to a hard-core processor. We demonstrate that the soft-core based warp processor achieves average speedups of 5.8 and energy reductions of 57% compared to the soft core alone. Our data shows that a soft-core based warp processor yields performance and energy consumption competitive with existing hard-core processors, thus expanding the usefulness of soft processor cores on FPGAs to a broader range of applications.

description: Software has jumped "out of the box" - it controls critical systems; it pervades business and commerce; it is embedded in myriad mechanisms; it infuses entertainment, communication, and other activities of everyday life. Designs for these applications are constrained not only by traditional considerations of capability and performance but also by economic, business, market, and policy issues and the context of intended use. The diversity of applications requires adaptability in responding to client needs, and the diversity of clients and contexts requires the ability to discriminate among criteria for success. As a result, software designers must also get out of their boxes: in addition to mastering traditional software development skills, they must understand the contextual issues that discriminate good solutions from merely competent ones. Current software engineering education, however, remains largely "in the box": it neglects the rich fabric of issues that lie between the client's problem and actual software development. At Carnegie Mellon we have addressed this major shortcoming with a course that teaches students to understand both the capabilities required by the client and the constraints imposed by the client's context. This paper presents our view of the engineering character of software engineering, describes the content and organization of our new course, reports on our experience from the first three offerings of our course, and suggests ways to adapt our course for other educational settings.
The Host Galaxy and The Extended Emission-Line Region of The Radio Galaxy 3C 79

description: We present extensive ground-based spectroscopy and HST imaging of 3C79, an FR II radio galaxy associated with a luminous extended emission-line region (EELR). Surface brightness modeling of an emission-line-free HST R-band image reveals that the host galaxy is a massive elliptical with a compact companion 0.8" away and 4 magnitudes fainter. The host galaxy spectrum is best described by an intermediate-age (1.3 Gyr) stellar population (4% by mass), superimposed on a 10 Gyr old population and a power law (α_λ = -1.8); the stellar populations are consistent with super-solar metallicities, with the best fit given by the 2.5 Z_sun models. We derive a dynamical mass of 4E11 M_sun within the effective radius from the velocity dispersion. The EELR spectra clearly indicate that the EELR is photoionized by the hidden central engine. Photoionization modeling shows evidence that the gas metallicity in both the EELR and the nuclear narrow-line region is mildly sub-solar (0.3 - 0.7 Z_sun) -- significantly lower than the super-solar metallicities deduced from typical active galactic nuclei in the SDSS. The more luminous filaments in the EELR exhibit a velocity field consistent with a common disk rotation. Fainter clouds, however, show high approaching velocities that are uncoupled with this apparent disk rotation. The striking similarities between this EELR and the EELRs around steep-spectrum radio-loud quasars provide further evidence for the orientation-dependent unification schemes. The metal-poor gas is almost certainly not native to the massive host galaxy. We suggest that the close companion galaxy could be the tidally stripped bulge of a late-type galaxy that is merging with the host galaxy. The interstellar medium of such a galaxy is probably the source for the low-metallicity gas in 3C79.

description: Penicillium species research has progressed far beyond their ability to produce secondary metabolites with potential biological applications, particularly as antimicrobial agents. In this work, Penicillium bilaiae EWB-3 was isolated from electronic waste and identified using morphological and molecular (ITS and β-tubulin regions) methods. For 15 days, Penicillium bilaiae EWB-3 was grown into Czapek Yeast Broth using an orbital shaker. Finally, the secondary metabolites in this strain’s filtrates were extracted using ethyl acetate. The agar well diffusion method tested this crude extract for antimicrobial activity. The Penicillium bilaiae EWB-3 extract exhibited strong antimicrobial potential against all tested microorganisms, including Pseudomonas aeruginosa, Bacillus cereus, Enterococcus faecalis, Escherichia coli, Salmonella typhimurium, Staphylococcus aureus, Methicillin-resistant Staphylococcus aureus, Klebsiella pneumoniae, Candida albicans and Aspergillus niger. With diameters of 31, 26, and 25 mm, the largest inhibition zones were observed against C. albicans, S. aureus, and E. faecalis, respectively. The presence of 24 active compounds was revealed by gas chromatography-mass spectrometry (GC-MS) analysis of the crude extract of Penicillium bilaiae EWB-3. The findings suggest that the secondary metabolite extract of Penicillium bilaiae EWB-3 could be a promising active pharmaceutical component.

description: We present an algorithm to generalize a plethora of well-known solutions to Einstein field equations describing spherically symmetric relativistic fluid spheres by relaxing the pressure isotropy condition on the system. By suitably fixing the model parameters in our formulation, we generate closed-form solutions which may be treated as anisotropic generalization of a large class of solutions describing isotropic fluid spheres. From the resultant solutions, a particular solution is taken up to show its physical acceptability. Making use of the current estimate of mass and radius of a known pulsar, the effects of anisotropic stress on the gross physical behaviour of a relativistic compact star is also highlighted.

Subjects: subject: Hardware Architecture (cs.AR)
subject: FOS: Computer and information sciences

description: This paper presents an infrastructure to test the functionality of the specific architectures output by a high-level compiler targeting dynamically reconfigurable hardware. It results in a suitable scheme to verify the architectures generated by the compiler, each time new optimization techniques are included or changes in the compiler are performed. We believe this kind of infrastructure is important to verify, by functional simulation, further research techniques, as far as compilation to Field-Programmable Gate Array (FPGA) platforms is concerned.

Estimation and inference for precision matrices of non-stationary time series
Creators: name: Ding, Xiucai

Publisher: name: arXiv
Year: 2018
Subjects: subject: Statistics Theory (math.ST)
subject: FOS: Mathematics

description: In this paper, we consider the estimation and inference of precision matrices of a rich class of locally stationary and nonlinear time series assuming that only one realization of the time series is observed. Using a Cholesky decomposition technique, we show that the precision matrices can be directly estimated via a series of least squares linear regressions with smoothly time-varying coefficients. The method of sieves is utilized for the estimation and is shown to be efficient and optimally adaptive in terms of estimation accuracy and computational complexity. We establish an asymptotic theory for a class of ${\cal L}^2$ tests based on the nonparametric sieve estimators. The latter are used for testing whether the precision matrices are diagonal or banded. A high dimensional Gaussian approximation result is established for a wide class of quadratic form of non-stationary and nonlinear processes, which is of interest by itself.
On the centrosymmetric permutations in a class

description: A permutation is centrosymmetric if it is fixed by a half-turn rotation of its diagram. Initially motivated by a question by Alexander Woo, we investigate the question of whether the growth rate of a permutation class equals the growth rate of its even-size centrosymmetric elements. We present various examples where the latter growth rate is strictly less, but we conjecture that the reverse inequality cannot occur. We conjecture that equality holds if the class is sum closed, and we prove this conjecture in the special case where the growth rate is at most $ξ\approx 2.30522$, using results from Pantone and Vatter on growth rates less than $ξ$. We prove one direction of inequality for sum closed classes and for some geometric grid classes. We end with preliminary findings on new kinds of growth-rate thresholds that are a little bit larger than $ξ$.
