description: The dominance of machine learning and the ending of Moore's law have renewed interests in Processor in Memory (PIM) architectures. This interest has produced several recent proposals to modify an FPGA's BRAM architecture to form a next-generation PIM reconfigurable fabric. PIM architectures can also be realized within today's FPGAs as overlays without the need to modify the underlying FPGA architecture. To date, there has been no study to understand the comparative advantages of the two approaches. In this paper, we present a study that explores the comparative advantages between two proposed custom architectures and a PIM overlay running on a commodity FPGA. We created PiCaSO, a Processor in/near Memory Scalable and Fast Overlay architecture as a representative PIM overlay. The results of this study show that the PiCaSO overlay achieves up to 80% of the peak throughput of the custom designs with 2.56x shorter latency and 25% - 43% better BRAM memory utilization efficiency. We then show how several key features of the PiCaSO overlay can be integrated into the custom PIM designs to further improve their throughput by 18%, latency by 19.5%, and memory efficiency by 6.2%.

description: This paper focuses on the creation of a new, publicly available Wi-Fi probe request dataset. Probe requests belong to the family of management frames used by the 802.11 (Wi-Fi) protocol. As the situation changes year by year, and technology improves probe request studies are necessary to be done on up-to-date data. We provide a month-long probe request capture in an office environment, including work days, weekends, and holidays consisting of over 1 400 000 probe requests. We provide a description of all the important aspects of the dataset. Apart from the raw packet capture we also provide a Radio Map (RM) of the office to ensure the users of the dataset have all the possible information about the environment. To protect privacy, user information in the dataset is anonymized. This anonymization is done in a way that protects the privacy of users while preserving the ability to analyze the dataset to almost the same level as raw data. Furthermore, we showcase several possible use cases for the dataset, like presence detection, temporal Received Signal Strength Indicator (RSSI) stability, and privacy protection evaluation.

GAMETOPHYTE AND SPOROPHYTE CROSSTALK DURING FERTILIZATION IN ARABIDOPSIS
Creators: name: LEO, GIULIA
Publisher: name: Universit� degli Studi di Milano
Year: 2018

description: Arabidopsis thaliana seeds comprise three tissues, which are genetically and functionally distinct. However, in order to ensure a correct seed development, a communication and coordination of them is strictly necessary. The seed coat is a five-layer tissue surrounding the female gametophyte. In the stk abs double mutant only four layers form this tissue: the endothelium, the innermost one, does not differentiate. Since the endothelium is a sporophytic layer directly in contact with the gametophyte before the fertilization and with the endosperm after the fertilization, we hypothesized a possible role of this layer in the communication between those tissues. In this work, the role of the endothelium has been investigated, as well as the role of the STK and ABS, the two MADS box transcription factors required for endothelium differentiation. An additional interesting phenotype of the stk abs double mutant is the excessive amount of starch accumulating in the central cell of the female gametophyte. This might causes the partial sterility described for the double mutant. Combining stk abs with the gpt1 mutant, whose mature ovules do not accumulate starch, we found a partial recovery of the phenotype; this result support the idea that the excess of starch in the double mutant could physically prevent the correct fertilization process.

description: The one-matrix model is considered. The generating function of the correlation numbers is defined in such a way that this function coincide with the generating function of the Liouville gravity. Using the Kontsevich theorem we explain that this generating function is an analytic continuation of the generating function of the Topological gravity. We check the topological recursion relations for the correlation functions in the $p$-critical Matrix model.

description: The Tianlai cylinder array is a pathfinder for developing and testing 21cm intensity mapping techniques. In this paper, we use numerical simulation to assess how its measurement is affected by thermal noise and the errors in calibration and map-making process, and the error in the sky map reconstructed from a drift scan survey. Here we consider only the single frequency, unpolarized case. The beam is modelled by fitting to the electromagnetic simulation of the antenna, and the variations of the complex gains of the array elements are modelled by Gaussian processes. Mock visibility data is generated and run through our data processing pipeline. We find that the accuracy of the current calibration is limited primarily by the absolute calibration, where the error comes mainly from the approximation of a single dominating point source. We then studied the $m$-mode map-making with the help of Moore-Penrose inverse. We find that discarding modes with singular values smaller than a threshold could generate visible artifacts in the map. The impacts of the residue variation of the complex gain and thermal noise are also investigated. The thermal noise in the map varies with latitude, being minimum at the latitude passing through the zenith of the telescope. The angular power spectrum of the reconstructed map show that the current Tianlai cylinder pathfinder, which has a shorter maximum baseline length in the North-South direction, can measure modes up to $l \lesssim 2πb_{\rm NS}/λ\sim 200$ very well, but would lose a significant fraction of higher angular modes when noise is present. These results help us to identify the main limiting factors in our current array configuration and data analysis procedure, and suggest that the performance can be improved by reconfiguration of the array feed positions.

MOLECULAR CHARACTERIZATION OF RESISTANCE TO RADIATION IN A SMALL SUBSET OF TUMOR CELLS INDUCED BY JC VIRUS T-AG IN MICE
Creators: name: DONADONI, MARTINA
Publisher: name: Universit� degli Studi di Milano
Year: 2018

description: JCV is a small, naked tumor polyomavirus with an icosahedral capsids containing a circular, double-stranded DNA genome. Its genome is divided into early and late genes, separated by a non-coding control region (NCCR) containing the promoter, the origin of replication (ORI) and the enhancer elements. Early genes encode for large T antigen, small t antigen and three different T? proteins called T?135, T?136 and T?165. Late genes encode for the structural proteins VP1, VP2 and VP3, and the non-structural agnoprotein. JCV only replicates in human. In non-permissive cells, they are not able to support viral replication or expression of late genes. In those cells, only the transcription of early genes is observed, such as large T antigen. This leads to genome instability and inactivation of oncosoppressor proteins and eventually tumorigenesis. Cells derived from a murine brain tumor induced by JCV injection have shown different resistance to ionizing radiation. We cultured these BSB8-RR cells and characterized them comparing to the radiation sensitive BSB8 cells. Using MTT assay we showed a resistance to radiation to these cells, compare to the BSB8. We then performed cell-cycle analysis, colony formation assay e soft agar growth assay and we showed that BSB8-RR grow faster and they are more tumorigenic. Since we saw a decrease in the level of large T antigen expression in BSB8-RR, compared to BSB8, we hypothesized an involvement of large T antigen in DNA repair. Using DNA repair assays such as NHEJ and homologous recombination, we suggested that BSB8-RR cells may be resistant to radiation because they have increased homologous recombination activity, compared to the BSB8 cells. We suggested that this increase is due to the lower expression of large T antigen in BSB8-RR, that has been previously reported as inhibitor of homologous recombination. In conclusion, our data showed a more aggressive phenotype of BSB8-RR cells and a resistance to radiation that we suggested is due to the lower level of large T antigen in these cells, compared to BSB8.
THE HP VERSION OF THE VIRTUAL ELEMENT METHOD

Publisher: name: Universit� degli Studi di Milano
Year: 2018

description: The interest in Galerkin methods for the approximation of partial differential equations on polytopal meshes has recently grown. The virtual element method (VEM) is one of the most successful approaches enabling computation on such meshes. So far, only the h version of the method has been investigated; here, the convergence of the error is obtained by keeping fixed the dimension of local spaces, while refining the mesh. Contrarily, the p version of a Galerkin method consists in achieving convergence by keeping fixed the decomposition of the domain and increasing the dimension of local spaces. The combination of the h and p versions goes under the name of hp version of the method under consideration. The present thesis aims to dovetail the technology of VEM with the p and the hp refinement strategies. Particular emphasis is offered to the approximation of Poisson and Laplace problems, a priori and a posteriori error analysis, multigrid solvers, stabilization of the method and ill-conditioning of the stiffness matrix.

description: Since the initial report of the potential occurrence of room-temperature superconductivity under normal pressure [arXiv: 2307.12008], there has been significant interest in the field of condensed matter physics regarding Cu-doped Apatite (Pb10-xCux(PO4)6O). In this study, we performed temperature-dependent resistivity measurements on the synthesized Pb10-xCux(PO4)6O samples. The structure of the sample was confirmed to match the reference literature through X-ray diffraction analysis. Remarkably, we observed four distinct types of resistivity behaviors within samples from the same pellet: (1) A semiconductor-like behavior characterized by a decrease in resistivity as the temperature is lowered. (2) A gradual reduction in resistivity, reaching an exceptionally small value that falls below the resolution limits of our measurement equipment. (3) An abrupt drop in resistivity to a low value at ~ 250 K. (4) An almost linear reduction in resistivity exhibiting a transition at approximately 7 K (possibly associated with Pb). Following a thorough compositional analysis, we proposed a current percolation model, based on the formation of a Cu/Pb current channel, to elucidate the observed special resistivity behaviors. It is important to note that the Meissner effect was not observed in our magnetization measurements. Consequently, we reached the conclusion that the presence of superconductivity in Cu-doped Apatite has yet to be substantiated.

description: Field theories on the Groenewold-Moyal(GM) plane are studied using the Lehmann-Symanzik-Zimmermann(LSZ) formalism. The example of real scalar fields is treated in detail. The S-matrix elements in this non-perturbative approach are shown to be equal to the interaction representation S-matrix elements. This is a new non-trivial result: in both cases, the S-operator is independent of the noncommutative deformation parameter $θ_{μν}$ and the change in scattering amplitudes due to noncommutativity is just a time delay. This result is verified in two different ways. But the off-shell Green's functions do depend on $θ_{μν}$. In the course of this analysis, unitarity of the non-perturbative S-matrix is proved as well.

description: Soft magnetic dots in the form of thin rings have unique topological properties. They can be in a vortex state with no vortex core. Here, we study the magnon modes of such systems both analytically and numerically. In an external magnetic field, magnetic rings are characterized by easy-cone magnetization and shows a giant splitting of doublets for modes with the opposite value of the azimuthal mode quantum number. The effect of the splitting can be refereed as a magnon analog of the topology-induced Aharonov-Bohm effect. For this we develop an analytical theory to describe the non-monotonic dependence of the mode frequencies on the azimuthal mode number, influenced by the balance between the local exchange and non-local dipole interactions.

description: We consider synthetic materials consisting of self-coupled identical resonators carrying classical internal degrees of freedom. The architecture of such material is specified by the positions and orientations of the resonators. Our goal is to calculate the smallest C*-algebra that covers the dynamical matrices associated to a fixed architecture and adjustable internal structures. We give the answer in terms of a groupoid C*-algebra that can be canonically associated to a uniformly discrete subset of the group of isometries of the Euclidean space. Our result implies that the isomorphism classes of these C*-algebras split these architected materials into classes containing materials that are identical from the dynamical point of view.

description: In magnetic memories, the state of a ferromagnet is encoded in the orientation of its magnetization. The energy of the system is minimized when the magnetization is parallel or antiparallel to a preferred (easy) axis. These two stable directions define the logical bit. Under an external perturbation, the direction of magnetization can be controllably reversed and thus the bit flipped. Here, we theoretically design a topological analogue of the magnetic bit in the Su-Schrieffer-Heeger (SSH)-Holstein model, where we show that a transient external perturbation can lead to a permanent change in the electronic band topology.

description: We consider the problem of reconstructing a compact 3-manifold (with boundary) embedded in $\mathbb{R}^3$ from its cross-sections $\mathcal S$ with a given set of cutting planes $\mathcal P$ having arbitrary orientations. Using the obvious fact that a point $x \in \mathcal P$ belongs to the original object if and only if it belongs to $\mathcal S$, we follow a very natural reconstruction strategy: we say that a point $x \in \mathbb{R}^3$ belongs to the reconstructed object if (at least one of) its nearest point(s) in $\mathcal P$ belongs to $\mathcal S$. This coincides with the algorithm presented by Liu et al. in \cite{LB+08}. In the present paper, we prove that under appropriate sampling conditions, the output of this algorithm preserves the homotopy type of the original object. Using the homotopy equivalence, we also show that the reconstructed object is homeomorphic (and isotopic) to the original object. This is the first time that 3-dimensional shape reconstruction from cross-sections comes with theoretical guarantees.

description: We present results of high-resolution, low-temperature measurements of the Hall coefficient, thermopower, and specific heat on stoichiometric YbRh2Si2. They support earlier conclusions of an electronic (Kondo-breakdown) quantum critical point concurring with a field induced antiferromagnetic one. We also discuss the detachment of the two instabilities under chemical pressure. Volume compression/expansion (via substituting Rh by Co/Ir) results in a stabilization/weakening of magnetic order. Moderate Ir substitution leads to a non-Fermi-liquid phase, in which the magnetic moments are neither ordered nor screened by the Kondo effect. The so-derived zero-temperature global phase diagram promises future studies to explore the nature of the Kondo breakdown quantum critical point without any interfering magnetism.

On the information-theoretic limits of attributed graph alignment
Creators: name: Zhang, Ning
Publisher: name: University of British Columbia
Year: 2022

description: Graph alignment aims at recovering the vertex correspondence between two correlated graphs, which is a task that frequently occurs in graph mining applications such as social network analysis, computational biology, etc. Existing studies on graph alignment mostly identify the vertex correspondence by exploiting the graph structure similarity. However, in many real-world applications, additional information attached to individual vertices, such as the user profiles in social networks, might be publicly available. In this thesis, we consider the attributed graph alignment problem, where additional information attached to individuals, referred to as attributes, is incorporated to assist graph alignment. We establish both the achievability and converse results on recovering vertex correspondence exactly, where the conditions match for a wide range of practical regimes. Our results span the full spectrum between models that only consider graph structure similarity and models where only attribute information is available.

description: We present a high-performance N-body code for self-gravitating collisional systems accelerated with the aid of a new SIMD instruction set extension of the x86 architecture: Advanced Vector eXtensions (AVX), an enhanced version of the Streaming SIMD Extensions (SSE). With one processor core of Intel Core i7-2600 processor (8 MB cache and 3.40 GHz) based on Sandy Bridge micro-architecture, we implemented a fourth-order Hermite scheme with individual timestep scheme (Makino and Aarseth, 1992), and achieved the performance of 20 giga floating point number operations per second (GFLOPS) for double-precision accuracy, which is two times and five times higher than that of the previously developed code implemented with the SSE instructions (Nitadori et al., 2006b), and that of a code implemented without any explicit use of SIMD instructions with the same processor core, respectively. We have parallelized the code by using so-called NINJA scheme (Nitadori et al., 2006a), and achieved 90 GFLOPS for a system containing more than N = 8192 particles with 8 MPI processes on four cores. We expect to achieve about 10 tera FLOPS (TFLOPS) for a self-gravitating collisional system with N 105 on massively parallel systems with at most 800 cores with Sandy Bridge micro-architecture. This performance will be comparable to that of Graphic Processing Unit (GPU) cluster systems, such as the one with about 200 Tesla C1070 GPUs (Spurzem et al., 2010). This paper offers an alternative to collisional N-body simulations with GRAPEs and GPUs.

description: Denoising diffusion models have found applications in image segmentation by generating segmented masks conditioned on images. Existing studies predominantly focus on adjusting model architecture or improving inference, such as test-time sampling strategies. In this work, we focus on improving the training strategy and propose a novel recycling method. During each training step, a segmentation mask is first predicted given an image and a random noise. This predicted mask, which replaces the conventional ground truth mask, is used for denoising task during training. This approach can be interpreted as aligning the training strategy with inference by eliminating the dependence on ground truth masks for generating noisy samples. Our proposed method significantly outperforms standard diffusion training, self-conditioning, and existing recycling strategies across multiple medical imaging data sets: muscle ultrasound, abdominal CT, prostate MR, and brain MR. This holds for two widely adopted sampling strategies: denoising diffusion probabilistic model and denoising diffusion implicit model. Importantly, existing diffusion models often display a declining or unstable performance during inference, whereas our novel recycling consistently enhances or maintains performance. We show that, under a fair comparison with the same network architectures and computing budget, the proposed recycling-based diffusion models achieved on-par performance with non-diffusion-based supervised training. By ensembling the proposed diffusion and the non-diffusion models, significant improvements to the non-diffusion models have been observed across all applications, demonstrating the value of this novel training method. This paper summarizes these quantitative results and discusses their values, with a fully reproducible JAX-based implementation, released at https://github.com/mathpluscode/ImgX-DiffSeg.

description: Carbon (C) and nitrogen (N) sequestration in plants and soil micro-organisms is considered as a major phenomenon against global warming. The modeling of this phenomenon aims at highlighting the role that the legumes-cereals mixed crop can play in the reduction of greenhouse gases. It is based on field experiments in maize (Zea mays L.)-common bean (Phaseolus vulgaris L.) intercropped system of the cereal agroecosystem in Setif region of Algeria. For this purpose, the MOMOS model was selected and validated in a calcareous soil and low phosphorus (P) conditions. It revealed some mechanisms that control the C and N sequestration in the compartments of the complex soil-plant-atmosphere-microorganism system. CN modeling results show that the daily growth of intercropped maize with common beans is positively correlated with the microbial CN transformation during the cropping cycle, under limited P and N conditions. Thus, this approach revealed the functional role of rhizobial symbiosis in maintaining the balance between the different C and N exchanges from soil to atmosphere and from atmosphere to soil.

description: Acute lymphoblastic leukemia (ALL), a malignancy of the bone marrow that is mainly caused by the uncontrolled proliferation of B- or T-lymphoblasts, is the most common form of pediatric cancer in Canada. Pediatric ALL is currently highly treatable due to advances in contemporary risk-directed ALL chemotherapy. However, some patients will be unresponsive to treatment and prognosis remains poor for patients undergoing relapse. Adverse side effects from drug toxicity used in chemotherapy also remain a major challenge. Recently, the lectin chaperones calreticulin (CALR) and calnexin (CANX), along with their co-chaperone, PDIA3, are increasingly implicated in the biological processes of various human cancers, along with their main role of facilitating protein folding in the endoplasmic reticulum (ER). Here, I investigated the role of CALR and PDIA3 in the promotion of pro-survival JAK/STAT signaling in human T-lymphoblasts. Previously, PDIA3 was found to be required for CALR localization in the cytosol. I generated CALR-/- and PDIA3-/- T-lymphoblasts using CRISPR-Cas9 to assess the effects of deficiency in total and cytosolic CALR on JAK/STAT signaling. CALR-/- and PDIA3-/- cells exhibited reduction in STAT3 phosphorylation compared to wildtype cells. This suggested that cytosolic CALR played a role in the regulation of STAT3 phosphorylation. Unexpectedly, I found that STAT5b mRNA was reduced in CALR-/- and PDIA3-/- Jurkat T-lymphoblasts, leading to an observed deficiency in STAT5 protein expression. This further emphasized the biological significance of CALR and PDIA3 in their extra-ER functions. To assess the clinical significance of CALR, CANX and PDIA3 expression in ALL, I analyzed publicly available transcriptome databases of pediatric ALL, which revealed the potential clinical utility of CALR and CANX mRNA expression in diagnostic tumour samples as biomarkers for predicting treatment response. Elevated CALR and CANX was correlated with the presence of minimal residual diseases (MRD) at the end of induction treatment in T-ALL and B-ALL respectively. As MRD remains a powerful prognostic indicator for risk stratification, the linkage between diagnostic tumour CALR and CANX mRNA expression and MRD status may provide important insights in treatment response for physicians at the time of diagnosis.

description: Nodal-line semimetals are commonly believed to exist in $\mathcal{PT}$ symmetric or mirror-rotation symmetric systems. Here, we find a flux-induced parameter-dimensional second-order nodal-line semimetal (SONLS) in a two-dimensional system without $\mathcal{PT}$ and mirror-rotation symmetries. It has coexisting hinge Fermi arcs and drumhead surface states. Meanwhile, we discover a flux-induced second-order topological insulator (SOTI). We then propose a Floquet engineering scheme to create exotic parameter-dimensional hybrid-order nodal-line semimetals with abundant nodal-line structures and widely tunable numbers of corner states in a SONLS and SOTI, respectively. Our results break the perception of SONLSs and supply a convenient way to artificially synthesize exotic topological phases by periodic driving.

description: Hintergrund Kohortenstudien sind prospektive Beobachtungsstudien. Sie sind in der Epidemiologie zum Studium von Krankheitsverläufen und Risikofaktoren fest etabliert. Hinsichtlich der Beschreibung und Bewertung von Qualitätsmerkmalen epidemiologischer Kohortenstudien existieren jedoch keine Standards. Ziel der Arbeit Im TMF(Technologie- und Methodenplattform für die vernetzte medizinische Forschung e. V.)-Projekt „Qualitätsmanagementstandards in Kohortenstudien“ sollte unter Beteiligung von Vertretern epidemiologischer Kohortenstudien ein Anforderungskatalog für Qualitätsmerkmale der Studienvorbereitung und Studiendurchführung zusammengestellt und bewertet werden. Material und Methoden Der Anforderungskatalog wurde auf Basis eines Konsensprozesses von Vertretern aus sieben deutschen epidemiologischen Kohortenstudien erstellt. Um die Struktur und Elemente einer Anforderungsliste zu definieren, fanden Expertentreffen statt. In drei Bewertungswellen wurden Wichtigkeit und Implementierungsgrad aller Anforderungen bewertet. Ergebnisse Konsentiert wurde ein Anforderungskatalog mit 138 Anforderungen, die in 10 Bereiche gegliedert sind: 1. Studiendokumente, 2. Instrumentenauswahl, 3. Untersuchungsplanung, 4. Organisationsstruktur, 5. Qualifizierung und Zertifizierung, 6. Probandenrekrutierung, 7. Untersuchungsvorbereitung und -durchführung, 8. Logistik und Instandhaltung, 9. Datenerfassung und Datenmanagement sowie 10. Reporting und Monitoring. Insgesamt 41 Anforderungen wurden als essenziell, 91 als wichtig und 6 als weniger wichtig bewertet. Diskussion Der Anforderungskatalog liefert Kohortenstudien Orientierungspunkte bei der Konzeption und Umsetzung, um eine möglichst hohe Struktur‑, Prozess- und Ergebnisqualität zu erzielen. Die Bewertung der Wichtigkeit und des Implementationsgrades einzelner Anforderungen hängt vom Studiendesign ab. Die Ergebnisse können mit Anpassungen auch für andere Studientypen relevant sein.

description: The Père David's Vole, Eothenomys melanogaster belongs to subfamily Arvicolinae. It is widespread in south China, and ranges into northern Southeast Asia. In this study, the complete mitochondrial genome sequence of Eothenomys melanogaster was determined. The mitogenome is 16,331 base pairs in length. The nucleotide sequence data of 12 heavy-strand protein-coding genes of E. melanogaster and other 17 rodents were used for phylogenetic analyses. Tree constructed using Bayesian phylogenetic methods demonstrated that E. melanogaster as a sister to E. chinensis, was clustered in subfamily Arvicolinae. The monophyly of the genus Eothenomys was supported as well with Eothenomys sister to the genus Myodes.

description: We study spherically symmetric static spacetimes generally filled with an anisotropic fluid in the nonrelativistic general covariant theory of gravity. In particular, we find that the vacuum solutions are not unique, and can be expressed in terms of the $U(1)$ gauge field $A$. When solar system tests are considered, severe constraints on $A$ are obtained, which seemingly pick up the Schwarzschild solution uniquely. In contrast to other versions of the Horava-Lifshitz theory, non-singular static stars made of a perfect fluid without heat flow can be constructed, due to the coupling of the fluid with the gauge field. These include the solutions with a constant pressure. We also study the general junction conditions across the surface of a star. In general, the conditions allow the existence of a thin matter shell on the surface. When applying these conditions to the perfect fluid solutions with the vacuum ones as describing their external spacetimes, we find explicitly the matching conditions in terms of the parameters appearing in the solutions. Such matching is possible even without the presence of a thin matter shell.

description: Subretinal injection methods and other procedures for treating retinal conditions and diseases (many considered incurable) have been limited in scope due to limited human motor control. This study demonstrates the next generation, cooperatively controlled Steady-Hand Eye Robot (SHER 3.0), a precise and intuitive-to-use robotic platform achieving clinical standards for targeting accuracy and resolution for subretinal injections. The system design and basic kinematics are reported and a deflection model for the incorporated delta stage and validation experiments are presented. This model optimizes the delta stage parameters, maximizing the global conditioning index and minimizing torsional compliance. Five tests measuring accuracy, repeatability, and deflection show the optimized stage design achieves a tip accuracy of <30 $μ$m, tip repeatability of 9.3 $μ$m and 0.02°, and deflections between 20-350 $μ$m/N. Future work will use updated control models to refine tip positioning outcomes and will be tested on in vivo animal models.

description: Labeling neural network submodules with human-legible descriptions is useful for many downstream tasks: such descriptions can surface failures, guide interventions, and perhaps even explain important model behaviors. To date, most mechanistic descriptions of trained networks have involved small models, narrowly delimited phenomena, and large amounts of human labor. Labeling all human-interpretable sub-computations in models of increasing size and complexity will almost certainly require tools that can generate and validate descriptions automatically. Recently, techniques that use learned models in-the-loop for labeling have begun to gain traction, but methods for evaluating their efficacy are limited and ad-hoc. How should we validate and compare open-ended labeling tools? This paper introduces FIND (Function INterpretation and Description), a benchmark suite for evaluating the building blocks of automated interpretability methods. FIND contains functions that resemble components of trained neural networks, and accompanying descriptions of the kind we seek to generate. The functions span textual and numeric domains, and involve a range of real-world complexities. We evaluate methods that use pretrained language models (LMs) to produce descriptions of function behavior in natural language and code. Additionally, we introduce a new interactive method in which an Automated Interpretability Agent (AIA) generates function descriptions. We find that an AIA, built from an LM with black-box access to functions, can infer function structure, acting as a scientist by forming hypotheses, proposing experiments, and updating descriptions in light of new data. However, AIA descriptions tend to capture global function behavior and miss local details. These results suggest that FIND will be useful for evaluating more sophisticated interpretability methods before they are applied to real-world models.

A Maximum Force Perspective on Black Hole Thermodynamics, Quantum Pressure, and Near-Extremality

description: I re-examined the notion of the thermodynamic force constructed from the first law of black hole thermodynamics. In general relativity, the value of the charge (or angular momentum) at which the thermodynamic force equals the conjectured maximum force $F=1/4$ is found to correspond to $Q^2/M^2=8/9$ (respectively, $a^2/M^2=8/9$), which is known in the literature to exhibit some special properties. This provides a possible characterization of near-extremality. In addition, taking the maximum force conjecture seriously amounts to introducing a pressure term in the first law of black hole thermodynamics. This resolves the factor of two problem between the proposed maximum value $F=1/4$ and the thermodynamic force of Schwarzschild spacetime $F=1/2$. Surprisingly it also provides another indication for the instability of the inner horizon. For a Schwarzschild black hole, under some reasonable assumptions, this pressure can be interpreted as being induced by the quantum fluctuation of the horizon position, effectively giving rise to a diffused "shell" of characteristic width $\sqrt{M}$. The maximum force can therefore, in some contexts, be associated with inherently quantum phenomena. Some implications are discussed as more questions are raised.
