World literature(s). Traduzioni e storia letteraria nazionale
Creators: name: Sisto, Michele
Publisher: name: Status Quaestionis
Year: 2024

description: If world literature is primarily constituted through translations, it cannot be conceived as a unitary repertoire but rather as a plurality of repertoires: indeed, through the act of translation, diverse national cultures produce an equal number of world literatures. Drawing upon recent advancements in comparative literature and translation studies, this essay explores the possibility of rewriting literary history—beginning with the case of Italian literature—by structurally incorporating translated literature.

description: As of Aug. 2020, coronavirus disease 2019 (COVID-19) is still spreading in the world. In Japan, the Ministry of Health, Labor, and Welfare developed "COVID-19 Contact-Confirming Application (COCOA)," which was released on Jun. 19, 2020. By utilizing COCOA, users can know whether or not they had contact with infected persons. If those who had contact with infectors keep staying at home, they may not infect those outside. However, effectiveness decreasing the number of infectors depending on the app's various usage parameters is not clear. If it is clear, we could set the objective value of the app's usage parameters (e.g., the usage rate of the total populations) and call for installation of the app. Therefore, we develop a multi-agent simulator that can express COVID-19 spreading and usage of the apps, such as COCOA. In this study, we describe the simulator and the effectiveness of the app in various scenarios. The result obtained in this study supports those of previously conducted studies.

First record of an Odontaspidid shark in Ascension Island waters
Creators: name: Richardson, Andrew J.
Publisher: name: Arquipelago - Life and Marine Sciences
Year: 2019

description: The occurrence of the poorly understood shark species Odontapsis ferox is reported at an oceanic seamount in the central south Atlantic, within the Exclusive Economic Zone of Ascension Island. The presence of the species at this location is confirmed by the discovery of a tooth embedded in scientific equipment, and footage of at least one animal on autonomous underwater video. The new record of this shark species at this location demonstrates the knowledge gaps which still exist at many remote, oceanic structures and their candidacy for status as important conservation areas.

Short term effects of irradiance on the growth of Pterocladiella capillacea (Gelidiales, Rhodophyta)
Creators: name: Patarra, Rita F.
Publisher: name: Arquipelago - Life and Marine Sciences
Year: 2019

description: Pterocladiella capillacea has been economically exploited for agar extraction in the Azores for many years. Harvesting dropped to a full stop in the early 1990s due to a population collapse, but restarted in 2013. Since then it has been intensively harvested and overexploitation must be prevented, with both sustainable harvesting and effective cultivation practices. This study represents the first attempt to determine optimal conditions for P. capillacea production in the Azores, and evaluates its vegetative growth in two experiments using von Stosch’s medium designed to test entire thallus and tips portions response to different irradiances (30, 70 and 150 μmol photons m-2 s-1). The best relative growth rate (RGR) was recorded at 150 μmol photons m−2 s−1 for the entire thalli and tips after two-weeks and three-weeks, respectively, indicating that an acclimation period is necessary to assure the growth of this alga under experimental conditions. Higher RGR was obtained at higher irradiance (3.98 ± 2.10% fm day-1), but overall, growth rates were low or negative. Epiphytes were a serious problem towards the end of the entire thallus experiments, where Feldmannia irregularis proliferate at all irradiances. Future cultivation approaches complemented with other relevant environmental factors (e.g. pH, photoperiod, salinity), are recommended.

description: In this paper, we propose a probabilistic consensus-based multi-robot search strategy that is robust to communication link failures, and thus is suitable for disaster affected areas. The robots, capable of only local communication, explore a bounded environment according to a random walk modeled by a discrete-time discrete-state (DTDS) Markov chain and exchange information with neighboring robots, resulting in a time-varying communication network topology. The proposed strategy is proved to achieve consensus, here defined as agreement on the presence of a static target, with no assumptions on the connectivity of the communication network. Using numerical simulations, we investigate the effect of the robot population size, domain size, and information uncertainty on the consensus time statistics under this scheme. We also validate our theoretical results with 3D physics-based simulations in Gazebo. The simulations demonstrate that all robots achieve consensus in finite time with the proposed search strategy over a range of robot densities in the environment.

description: Covariance matrices play an important role in many multivariate techniques and hence a good covariance estimation is crucial in this kind of analysis. In many applications a sparse covariance matrix is expected due to the nature of the data or for simple interpretation. Hard thresholding, soft thresholding, and generalized thresholding were therefore developed to this end. However, these estimators do not always yield well-conditioned covariance estimates. To have sparse and well-conditioned estimates, we propose doubly shrinkage estimators: shrinking small covariances towards zero and then shrinking covariance matrix towards a diagonal matrix. Additionally, a richness index is defined to evaluate how rich a covariance matrix is. According to our simulations, the richness index serves as a good indicator to choose relevant covariance estimator.
Aspetti e frontiere del racconto biografico

Publisher: name: Status Quaestionis
Year: 2024

description: The present essay attempts to demonstrate how and why 19th century forms and 20th century variants of biofiction mark an important paradigm shift in the recent history of the literary field. They prove that in the narrative genres of contemporary age life is not perceived as the object of an integral representation but is rather treated as the subject of a recognition, that of a reality as fragmentary as the manners of an art founded on the temporal imbalance between βίος and fiction. The essay aims to clarify aspects and frontiers of biofiction dating back to European modernity: the fictional matrix that is implied in the dynamic between narrativization and reconstruction; the illusory rigour of completeness; the constant fragmentariness; the alternation between topics of uniqueness and discourse of infamy; the atmospheric definition of the untimely – with the purpose of providing, through a combined exercise of theoretical morphology and diachronic genealogy, the fundamental coordinates for the metahistorical interpretation of modern biofiction.

description: We compute the Bekenstein-Hawking entropy of near-extremal asymptotically AdS$_4$ electrically charged rotating black holes using three different methods: (i) from the gravity solution, (ii) from the near-horizon Kerr/CFT correspondence and (iii) from the boundary conformal field theory. The results from these three different approaches match exactly, giving us a unique and universal expression for the entropy and the microstate counting of near-extremal AdS black holes via the AdS/CFT correspondence. In the second method, we extend the Kerr/CFT correspondence to the near-extremal case to compute the left and right central charges. We also use hidden conformal symmetry of the near-horizon geometry to compute the Frolov-Thorne temperatures. From the results of the near-extremal AdS$_4$ black hole entropy, we provide a microscopic foundation for Hawking radiation.

title: Optimisation of optical neuromorphic computing systems
Creators: name: Neill, Oliver D.
Publisher: name: University of Glasgow
Year: 2025

description: As the exponential scaling of computing systems predicted by Moore’s law begins to slow, in part due to reaching fundamental physical limitations in the continued miniaturisation of transistors, the development of novel unconventional computing technologies with improved scaling laws is becoming increasingly important. Unconventional computing systems use substrates other than silicon transistors to encode and process information. As an umbrella term, it encompasses fields such as analogue, physical and neuromorphic computing, which focus on computation through continuous variables, complex physical processes, and artificial neurons respectively.

While there exist a wide range of physical processes and dynamics which one could imagine exploiting to process information, the key challenge is in designing scalable systems which can be easily programmed to solve specific tasks. The success of existing computing technologies relies on the strong predictions which can be made about their behaviour. When using alternative physical processes for computing, one must work against noise, instabilities, and unmeasurable internal dynamics, which can limit the determinism and predictability of a system.

In the following work, we present a series of results on optimising physical computing systems with these factors in mind, where we focus primarily on optical substrates due to their natural potential for energy efficiency, speed and parallelism. We approach this in two ways, first considering the design of high-level system architectures suitable for computing, and secondly considering ways of programming and optimising these systems to solve specific tasks. In the case of the former, we introduce a new physical computing architecture which uses quantum resources to improve scaling over an equivalent classical counterpart, and which is realisable with currently available technologies. In the latter, we apply meta-learning and reinforcement learning techniques to develop new optimisation strategies for training physical neural networks in situ in a scalable way. Throughout, we analyse the criteria necessary for efficiency and scalability, while also considering ways in which we can ensure the resulting systems are accessible and sustainable.

Beyond these examples, we discuss the broader motivations and requirements for the practical adoption of unconventional and neuromorphic computing systems, and the potential impact they could have on the scaling of future computing technologies, including the efforts towards realising artificial general intelligence and artificial consciousness.

Inferring Microbial Biomass Yield and Cell Weight using Probabilistic Macrochemical Modeling

description: Growth rates and biomass yields are key descriptors used in microbiology studies to understand how microbial species respond to changes in the environment. Of these, biomass yield estimates are typically obtained using cell counts and measurements of the feed substrate. These quantities are perturbed with measurement noise however. Perhaps most crucially, estimating biomass from cell counts, as needed to assess yields, relies on an assumed cell weight. Noise and discrepancies on these assumptions can lead to significant changes in conclusions regarding the microbes' response. This article proposes a methodology to address these challenges using probabilistic macrochemical models of microbial growth. It is shown that a model can be developed to fully use the experimental data, relax assumptions and greatly improve robustness to a priori estimates of the cell weight, and provides uncertainty estimates of key parameters. This methodology is demonstrated in the context of a specific case study and the estimation characteristics are validated in several scenarios using synthetically generated microbial growth data.

description: A triethylene glycol di-imine locked triazole linked bis-calix[4]arene conjugate L has been synthesised and characterised. Conjugate L exhibits high fluorescence enhancement towards Zn2+ among the 13 metal ions studied down to a lower detection limit of ∼12 ppb. The absorption and visual colour change experiments differentiated the Zn2+ from the other metal ions studied. The isolated zinc complex, [Zn2L] has been used as a chemo-sensing ensemble for the recognition of anions based on their binding affinities towards Zn2+. [Zn2L] was found to be sensitive and selective towards phosphate-bearing species and in particular to adenosine triphosphate (ATP2 − ) among the other 20 anions studied as observed based on the changes occurred in the fluorescence intensity. The selectivity of the ATP2 −  has been shown on the basis of the changes observed in the emission and absorption spectral studies. The lowest detectable concentration for ATP2 −  with the chemo-sensing ensemble [Zn2L] is 348 ppb in methanol. The fluorescence quenching by the phosphate-based anions has been modelled by molecular mechanics studies and found that the anions possessing two or more phosphate moieties can only bridge between the two zinc centres, and hence those possessing only one phosphate moiety (H2PO4−  and AMP2 − ) are ineffective.

description: Tensor decompositions, such as CANDECOMP/PARAFAC (CP), are widely used in a variety of applications, such as chemometrics, signal processing, and machine learning. A broadly used method for computing such decompositions relies on the Alternating Least Squares (ALS) algorithm. When the number of components is small, regardless of its implementation, ALS exhibits low arithmetic intensity, which severely hinders its performance and makes GPU offloading ineffective. We observe that, in practice, experts often have to compute multiple decompositions of the same tensor, each with a small number of components (typically fewer than 20), to ultimately find the best ones to use for the application at hand. In this paper, we illustrate how multiple decompositions of the same tensor can be fused together at the algorithmic level to increase the arithmetic intensity. Therefore, it becomes possible to make efficient use of GPUs for further speedups; at the same time the technique is compatible with many enhancements typically used in ALS, such as line search, extrapolation, and non-negativity constraints. We introduce the Concurrent ALS algorithm and library, which offers an interface to Matlab, and a mechanism to effectively deal with the issue that decompositions complete at different times. Experimental results on artificial and real datasets demonstrate a shorter time to completion due to increased arithmetic intensity.
Mass-suppressed effects in heavy quark diffusion

description: Many lattice studies of heavy quark diffusion originate from a colour-electric correlator, obtained as a leading term after an expansion in the inverse of the heavy-quark mass. In view of the fact that the charm quark is not particularly heavy, we consider subleading terms in the expansion. Working out correlators up to $O(1/M^2)$, we argue that the leading corrections are suppressed by $O(T/M)$, and one of them can be extracted from a colour-magnetic correlator. The corresponding transport coefficient is non-perturbative already at leading order in the weak-coupling expansion, and therefore requires a non-perturbative determination.

Love Law: The Aura of Prison Writing in Mexico, from the 1800s to the Present
Creators: name: Whitfield, Joey

Publisher: name: Status Quaestionis
Year: 2024

description: Prison writing has largely been excluded from the literary canon of the Spanish-speaking world, even though it encompasses key names that extend as far back as Cervantes in Spain and Lizardi in Mexico: two of the pioneers of what is now called the “novel”. Building on seminal analyses of Latin American literature by Roberto González Echevarría, Ángel Rama and Doris Sommer, this article addresses the following questions: What is the power of prison writing? How might we interpret its status as a genre, both in historical and contemporary terms? And what do contemporary forms of prison writing share with much older examples? To answer these questions, we analyze prison narratives from the nineteenth, twentieth, and twenty-first centuries, including well-known novels by José Joaquín Fernández de Lizardi and José Revueltas, and narratives by emerging writers from Susuki Lee, Águila del Mar, and Amatista Lee to Julio Grotten. Through an “auratic quality” that, we argue, derives from their ability to develop powerful counter-truths through the experience of confinement, these narratives reveal and resist the subjugation of the subject by the state as the latter intervenes violently in politics and private life. Our contention is that the power of prison writing lies in its ability to turn legal, state-sponsored discourse on its head through the production of alternative stories narrated from within prison and from below; and that these are simultaneously founded on legal discourse and its affective underside; on law and love.

Calix[4]arene-tetrathiafulvalene (TTF) conjugates 4a–d, fixed in cone conformation and comprising two smaller 1,2-bridges, were prepared by cyclisation of tetrakis-chloromethylated calix[4]arene 1 with 2,3-dithiolates of TTFs. Larger calix[4]arene-TTF macrocycles 14 and 15, also in cone conformation, contain 1,3-bridges and were synthesised by cyclisation of 2,6- and 2,7-dithiolates of TTFs with bis-bromomethylated calix[4]arene 7. Redox properties of new calix[4]arene-TTF conjugates were characterised using cyclic voltammetry.
Brexit, the Border and the Unification of Ireland. A Corpus-assisted Analysis of Irish Newspapers
Creators: name: Bibbò, Antonio
Publisher: name: Status Quaestionis
Year: 2024

description: This is an analysis of the discourses on Brexit in Irish newspapers. In order to explore such discourses, I built a corpus of newspaper articles on Brexit published in both the Republic of Ireland and in Northern Ireland, in different time spans, namely the period of the June 2016 referendum, the EU/Britain deal of 2020, and the announcement of the Windsor Framework in 2023. My corpus-assisted study aims to critically analyse how issues related to the consequences of Brexit were articulated in newspapers, in order to tease out differences in the language regarding the matter at hand at topical moments. This article primarily addresses key words and phrases related to partition within the corpus (e.g. border poll, hard border, united Ireland), as well as their collocational behaviour. The study investigates key changes in the discourse on both the Irish border and Irish unification during the 2016-2023 period, and considers how possible changes in terminology (e.g. shared island, new Ireland) can be evidence of a new type of discourse about unification that is slowly surfacing.

description: Topological materials with broken inversion symmetry can give rise to nonreciprocal responses, such as the current rectification controlled by magnetic fields via magnetochiral anisotropy. Bulk nonreciprocal responses usually stem from relativistic corrections and are always very small. Here we report our discovery that ZrTe5 crystals in proximity to a topological quantum phase transition present gigantic magnetochiral anisotropy, which is the largest ever observed to date. We argue that a very low carrier density, inhomogeneities, and a torus-shaped Fermi surface induced by breaking of inversion symmetry in a Dirac material are central to explain this extraordinary property.

The association constants (Ka) between receptors and dicarboxylic acids have been determined using UV–vis and NMR titration techniques. The binding constant (Ka) of succinic acid with R1 was observed maximum, which implies the optimum chain length selectivity for succinic acid. Theoretical calculation and molecular modelling using Gaussian 03 program also support the optimised receptor's cavity for succinic acid.

description: Millimeter-wave radars are being increasingly integrated into commercial vehicles to support new advanced driver-assistance systems by enabling robust and high-performance object detection, localization, as well as recognition - a key component of new environmental perception. In this paper, we propose a novel radar multiple-perspectives convolutional neural network (RAMP-CNN) that extracts the location and class of objects based on further processing of the range-velocity-angle (RVA) heatmap sequences. To bypass the complexity of 4D convolutional neural networks (NN), we propose to combine several lower-dimension NN models within our RAMP-CNN model that nonetheless approaches the performance upper-bound with lower complexity. The extensive experiments show that the proposed RAMP-CNN model achieves better average recall and average precision than prior works in all testing scenarios. Besides, the RAMP-CNN model is validated to work robustly under nighttime, which enables low-cost radars as a potential substitute for pure optical sensing under severe conditions.

description: While symbolic colour use has always played a conspicuous role in science research and education, the use of colour in historic diagrams remains a lacuna in the history of science. Investigating the colour use in diagrams often means uncovering a whole cosmology that is not otherwise explicit in the diagram itself. The periodic table is a salient and iconic example of non‐mimetic colour use in science. Andreas von Antropoff's (1924) rectangular table of recurrent rainbow colours is famous, as are Alcindo Flores Cabral's (1949) application of colour in his round snail form, using the RGB scheme, and Mazurs's (1967) pine tree system, consisting of warm and cold colours that he attributed to specific groups of elements—an attribution that we can relate back to humoralism and alchemy. From the first periodic tables in the 19th century, individual researchers have used different colour regimes. While standardization may play an obvious role in chemistry and its diagrams, all the more impressive is the anarchistic use of colour in the various diagrams which continue to be created. This article focuses on periodic tables in chemical journals and text books, and explores and compares the development of colour codes found in the few existing polychrome diagrams from the 1920s to the 1970s.
Freeze-in and freeze-out generation of lepton asymmetries after baryogenesis in the $ν$MSM

description: The $ν$MSM -- an extension of the Standard Model by three relatively light singlet Majorana fermions $N_{1,2,3}$ -- allows for the generation of lepton asymmetry which is several orders of magnitude larger than the observed baryon asymmetry of the Universe. The lepton asymmetry is produced in interactions of $N_{2,3}$ (with masses in the GeV region) at temperatures below the sphaleron freeze out $ T \lesssim 130$ GeV and can enhance the cosmological production of dark matter (DM) sterile neutrinos $N_1$ (with the mass of the keV scale) happening at $T \sim 200$ MeV due to active-sterile neutrino mixing. This asymmetry can be generated in freeze-in, freeze-out, or later in decays of heavy neutral leptons. In this work, we address the question of the magnitude of the late-time asymmetry (LTA) generated by the heavy neutral leptons $N_{2,3}$ during their freeze-in and freeze-out, leaving the decays for later work. We study how much of this asymmetry can survive down to the lower temperatures relevant for the sterile neutrino DM creation. We find that this LTA could result in the production of a sizeable fraction of dark matter. We also examine a role played by magnetic fields and the Abelian chiral anomaly in the generation of LTA, not accounted for in the previous studies. We argue that the production of LTA can be increased significantly and make an estimate of the influence of this effect.

description: The size limit of substituents allowing O-through-the-annulus rotation of substituted calix[4]arenes was further extended to the propargyloxy group in 24-propargyloxy-25,26,27-tris(N,N-dimethylcarbamoylmethoxy)-p-tert-butylcalix[4]arene by demonstrating its free but slow motion affording equilibrium between the partial cone and 1,2-alternate conformers. The effect of solvent and upper rim substituents R1 on the conformational inversion was investigated by means of 1H NMR. The rotational isomerisation of the parent (R1 = H) analogue could not unambiguously be detected. The experimental results were supported by comprehensive density functional theory studies.

description: The strength of a homogeneous polynomial (or form) is the smallest length of an additive decomposition expressing it whose summands are reducible forms. Using polynomial functors, we show that the set of forms with bounded strength is not always Zariski-closed. More specifically, if the ground field is algebraically closed, we prove that the set of quartics with strength $\leq3$ is not Zariski-closed for a large number of variables.

Come il ragno a Nazca: per un’archetipologia junghiana dell’aracnide in Dino Buzzati, Tommaso Landolfi e Primo Levi
Creators: name: Caiola, Caterina

description: The following article explores the archetypal poignancy of the spider in twentieth-century Italian literature by analyzing the stories of Tommaso Landolfi, Primo Levi and Dino Buzzati. Despite their distinct poetics, they simultaneously used various kinds of animal figures sostructurally throughout their careers, that it makes sense to investigate the actual bestiaries derived from their productions. The weight that magical and primitive culture, as well as their individual psychology, had in this phenomenon will be investigated and culturally motivated, through a study that aims to probe our collective imagination, somewhere between the definition given by psychoanalyst Jung and the reconstruction of folk beliefs given by anthropologists such as De Martino. Not by chance, we propose the spider as emblematic to our mythical-ritual system of inquiry, as well as one of the most significant archetypal animal images in literature, magic, phobia, and folklore.

description: Hawksbills (Eretmochelys imbricata) and green turtles (Chelonia mydas) are the predominant nesting sea turtle species on the beaches of Príncipe Island in the Gulf of Guinea. The extent of nesting has been largely unknown, but such information is essential for management and conservation. Our study is the first island-wide nesting assessment. Results from the survey, conducted from 1 December 2009 to 18 January 2010 (during peak nesting season), show that the potential suitable nesting area (10 km) is scattered around the island’s 50 beaches. Sea turtles nested on 32 of the beaches (hawksbills, 20; green turtles, 28) and used 7.5 km of the suitable nesting habitat (hawksbills, 5.8 km; green turtles, 7.0 km). We estimated that 101 (95% CI = 86–118) clutches were deposited by 17-29 hawksbills and 1088 (95% CI = 999–1245) clutches were deposited by 166-429 green turtles on Príncipe from November 2009 to February 2010 (nesting season). Long-term green turtle nest count data collected from 2007/08 to 2015/16 suggest a positive trend. Analyses of clutch densities in relation to beach characteristics suggested that both species preferred areas where human presence is lower, which coincided with the most sheltered areas. These findings should be used to inform coastal planning and minimize impacts on nesting beaches, as Príncipe is currently targeted for tourism development. Overall, results highlight that Príncipe beaches are very important for the conservation of West African hawksbill and green turtle populations.

title: Decision-making stress and satisfaction
title: a cognitive-affective model

Creators: name: Lucas, James Joseph

description: Researchers have utilised normative, heuristic, and process approaches to understand people’s decision-making but with less focus on how satisfying these decisions are. There is a gap in the literature regarding the contribution of appraisals, stress, coping, and metacognitive awareness and acceptance to decision satisfaction. The conflict approach to decision-making, cognitive theories of stress and coping, and recent developments in cognitive-behavioural therapies may further our understanding of decision satisfaction. A Cognitive-Affective Model of Decision-Making Stress and Satisfaction was developed from the literature and tested in a three-phase longitudinal study. In Phase One (n = 182 adults; Mage = 40.48 years; SD = 12.04), a modified model focusing on a decision related to participants’ occupation or study was supported. It explained 61% of the variance in participants’ decision satisfaction. In Phase Two (n = 84; Mage = 39.43 years, SD = 11.94), the model was found to be invariant across a family/relationship decision. In Phase Three (n = 54; Mage = 39.54 years; SD = 12.29), model replication was not feasible although mean differences in the model’s manifest factors across occupation/study, family/relationship, and physical/mental health decision types were small or not significant, suggesting that the model is potentially invariant across all three decision types. The Cognitive-Affective Model of Decision-Making Stress and Satisfaction has both theoretical and practical implications for clinicians and researchers alike. These implications are discussed together with the thesis’ limitations and avenues for future research.
Decentralized Multi-target Tracking with Multiple Quadrotors using a PHD Filter

description: We consider a scenario in which a group of quadrotors is tasked at tracking multiple stationary targets in an unknown, bounded environment. The quadrotors search for targets along a spatial grid overlaid on the environment while performing a random walk on this grid modeled by a discrete-time discrete-state (DTDS) Markov chain. The quadrotors can transmit their estimates of the target locations to other quadrotors that occupy their current location on the grid; thus, their communication network is time-varying and not necessarily connected. We model the search procedure as a renewal-reward process on the underlying DTDS Markov chain. To accommodate changes in the set of targets observed by each quadrotor as it explores the environment, along with uncertainties in the quadrotors' measurements of the targets, we formulate the tracking problem in terms of Random Finite Sets (RFS). The quadrotors use RFS-based Probability Hypothesis Density (PHD) filters to estimate the number of targets and their locations. We present a theoretical estimation framework, based on the Gaussian Mixture formulation of the PHD filter, and preliminary simulation results toward extending existing approaches for RFS-based multi-target tracking to a decentralized multi-robot strategy for multi-target tracking. We validate this approach with simulations of multi-target tracking scenarios with different densities of robots and targets, and we evaluate the average time required for the robots in each scenario to reach agreement on a common set of targets.

description: Transformer based models, like BERT and RoBERTa, have achieved state-of-the-art results in many Natural Language Processing tasks. However, their memory footprint, inference latency, and power consumption are prohibitive efficient inference at the edge, and even at the data center. While quantization can be a viable solution for this, previous work on quantizing Transformer based models use floating-point arithmetic during inference, which cannot efficiently utilize integer-only logical units such as the recent Turing Tensor Cores, or traditional integer-only ARM processors. In this work, we propose I-BERT, a novel quantization scheme for Transformer based models that quantizes the entire inference with integer-only arithmetic. Based on lightweight integer-only approximation methods for nonlinear operations, e.g., GELU, Softmax, and Layer Normalization, I-BERT performs an end-to-end integer-only BERT inference without any floating point calculation. We evaluate our approach on GLUE downstream tasks using RoBERTa-Base/Large. We show that for both cases, I-BERT achieves similar (and slightly higher) accuracy as compared to the full-precision baseline. Furthermore, our preliminary implementation of I-BERT shows a speedup of 2.4-4.0x for INT8 inference on a T4 GPU system as compared to FP32 inference. The framework has been developed in PyTorch and has been open-sourced.

description: A simple and powerful one-pot reaction method was developed for the synthesis of heteracalixaromatics. In the presence of a base, one-pot macrocyclic condensation reaction between cyanuric chloride and 1,3-phenylene diols and diamines proceeded effectively under very mild conditions to afford a number of functionalised oxygen and nitrogen-bridged calix[2]arene[2]triazines in 33–54% yields. The method was applied in a multigram-scale (14.4 g) preparation of tetraoxacalix[2]arene[2]triazine.
