description: In large-scale datacenters, memory failure is a common cause of server crashes, with Uncorrectable Errors (UEs) being a major indicator of Dual Inline Memory Module (DIMM) defects. Existing approaches primarily focus on predicting UEs using Correctable Errors (CEs), without fully considering the information provided by error bits. However, error bit patterns have a strong correlation with the occurrence of UEs. In this paper, we present a comprehensive study on the correlation between CEs and UEs, specifically emphasizing the importance of spatio-temporal error bit information. Our analysis reveals a strong correlation between spatio-temporal error bits and UE occurrence. Through evaluations using real-world datasets, we demonstrate that our approach significantly improves prediction performance by 15% in F1-score compared to the state-of-the-art algorithms. Overall, our approach effectively reduces the number of virtual machine interruptions caused by UEs by approximately 59%.

description: New data on the production of protons, anti-protons and neutrons in p+p interactions are presented. The data come from a sample of 4.8 million inelastic events obtained with the NA49 detector at the CERN SPS at 158 GeV/c beam momentum. The charged baryons are identified by energy loss measurement in a large TPC tracking system. Neutrons are detected in a forward hadronic calorimeter. Inclusive invariant cross sections are obtained in intervals from 0 to 1.9 GeV/c (0 to 1.5 GeV/c) in transverse momentum and from -0.05 to 0.95 (-0.05 to 0.4) in Feynman x for protons (anti-protons), respectively. pT integrated neutron cross sections are given in the interval from 0.1 to 0.9 in Feynman x. The data are compared to a wide sample of existing results in the SPS and ISR energy ranges as well as to proton and neutron measurements from HERA and RHIC.

The abbeys of Westminster and Syon in pre-Reformation England : an appraisal of monastic ideals, roles and contributions in English religious life and cultural traditions
Creators: name: Reyes-Lijauco, Melina
Publisher: name: University Of Tasmania
Year: 2023

description: On the eve of the Reformation, was traditional religion on the decline? During the last four decades before the Dissolution in England, was the monastic institution stagnant, failing, unpopular and irrelevant? This thesis examines the English abbeys of Westminster and Syon and presents facts and arguments to show evidence of vigour and vitality of the English monastic institution on the eve of its dissolution. During the late Middle Ages, especially the period 1500-1540, both abbeys passed numerous criteria of vitality: successful recruitment, enormous wealth, popularity and high patronage. Spiritually, both abbeys successfully adhered to the traditional monastic ideals of contemplative life coupled with the outward-looking duty of lay pastoralship in the form of evangelisation and social services. Culturally, both abbeys showed cultivation of literary and musical culture and patronage of contemporary intellectual, artistic and technological development. - Contrary to the popular belief that monastic life was in decline during the late medieval period, both the Westminster and Syon monastic communities demonstrated spiritual vitality, played proactive roles in the community and contributed immensely in the religious, cultural and socio-economic life of the English nation up until their dissolutions.

We devise a single-photon interferometer to realize coherent superpositions of two sequences of photon addition and subtraction. Depending on the interference outcome, the commutation relation is directly proven or a highly nonclassical state is produced. Experimental imperfections are assessed to show that the realization of the scheme is highly feasible.

description: We consider the problem of estimating differences in two Gaussian graphical models (GGMs) which are known to have similar structure. The GGM structure is encoded in its precision (inverse covariance) matrix. In many applications one is interested in estimating the difference in two precision matrices to characterize underlying changes in conditional dependencies of two sets of data. Existing methods for differential graph estimation are based on single-attribute (SA) models where one associates a scalar random variable with each node. In multi-attribute (MA) graphical models, each node represents a random vector. In this paper, we analyze a group lasso penalized D-trace loss function approach for differential graph learning from multi-attribute data. An alternating direction method of multipliers (ADMM) algorithm is presented to optimize the objective function. Theoretical analysis establishing consistency in support recovery and estimation in high-dimensional settings is provided. Numerical results based on synthetic as well as real data are presented.

Squash Operator and Symmetry
Creators: name: Tsurumaru, Toyohiro
Publisher: name: arXiv
Year: 2009
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: This paper begins with a simple proof of the existence of squash operators compatible with the Bennett-Brassard 1984 (BB84) protocol which suits single-mode as well as multi-mode threshold detectors. The proof shows that, when a given detector is symmetric under cyclic group C_4, and a certain observable associated with it has rank two as a matrix, then there always exists a corresponding squash operator. Next, we go on to investigate whether the above restriction of "rank two" can be eliminated; i.e., is cyclic symmetry alone sufficient to guarantee the existence of a squash operator? The motivation behind this question is that, if this were true, it would imply that one could realize a device-independent and unconditionally secure quantum key distribution protocol. However, the answer turns out to be negative, and moreover, one can instead prove a no-go theorem that any symmetry is, by itself, insufficient to guarantee the existence of a squash operator.

RecJPQ: Training Large-Catalogue Sequential Recommenders
Creators: name: Petrov, Aleksandr V.
name: Macdonald, Craig
Publisher: name: arXiv
Year: 2023
Subjects: subject: Information Retrieval (cs.IR)
subject: FOS: Computer and information sciences

description: Sequential Recommendation is a popular recommendation task that uses the order of user-item interaction to model evolving users' interests and sequential patterns in their behaviour. Current state-of-the-art Transformer-based models for sequential recommendation, such as BERT4Rec and SASRec, generate sequence embeddings and compute scores for catalogue items, but the increasing catalogue size makes training these models costly. The Joint Product Quantisation (JPQ) method, originally proposed for passage retrieval, markedly reduces the size of the retrieval index with minimal effect on model effectiveness, by replacing passage embeddings with a limited number of shared sub-embeddings. This paper introduces RecJPQ, a novel adaptation of JPQ for sequential recommendations, which takes the place of item embeddings tensor and replaces item embeddings with a concatenation of a limited number of shared sub-embeddings and, therefore, limits the number of learnable model parameters. The main idea of RecJPQ is to split items into sub-item entities before training the main recommendation model, which is inspired by splitting words into tokens and training tokenisers in language models. We apply RecJPQ to SASRec, BERT4Rec, and GRU4rec models on three large-scale sequential datasets. Our results showed that RecJPQ could notably reduce the model size (e.g., 48% reduction for the Gowalla dataset with no effectiveness degradation). RecJPQ can also improve model performance through a regularisation effect (e.g. +0.96% NDCG@10 improvement on the Booking.com dataset). Overall, RecJPQ allows the training of state-of-the-art transformer recommenders in industrial applications, where datasets with millions of items are common.

description: In the present work, we study different aspects of Lorentz and CPT symmetry violation in extended massless QED. By following the observation that the 2+1 dimensional Maxwell-Chern-Simons theory can be originated from the 3+1 dimensional Chern-Simons-like action, we also focus on the fermion sector to relate the 3+1 dimensional extended massless QED to 2+1 dimensional massive QED. We take advantage of this to state that the Chern-Simons-like action in extended massless QED can be induced with its coefficient being well defined and finite just as its 2+1 counterpart. We make use of three different regularization schemes by inducting the Chern-Simons-like in 3+1 dimensions to support this conjecture.

Cen A as TeV gamma-ray and possible UHE cosmic-ray source

Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: Context: The most nearby active galaxy Cen A has attracted considerable attention as a detected TeV gamma-ray and possible ultra-high energy (UHE) cosmic-ray emitter. Aims: We investigate the efficiency of particle acceleration close to the supermassive black hole (BH) horizon assuming that accretion in the innermost part of the disk occurs in an advection-dominated (ADAF) mode. Methods: We analyze the constraints on the achievable particle energies imposed by radiative losses and corotation for conditions inferred from observations. Results: We show that for an underluminous source such as Cen A, centrifugally accelerated electrons may reach Lorentz factors of up to $γ\sim (10^7-10^8)$, allowing inverse Compton (Thomson) upscattering of ADAF sub-mm disk photons into the TeV regime with an associated maximum (isotropic) luminosity of the order of a few times $10^{39}$ erg/s. Upscattering of Comptonized disk photons is expected to lead to a TeV spectrum $L_ν \propto ν^{-α_c}$ with a spectral index $α_c \simeq (1.5-1.9)$, consistent with H.E.S.S. results. The corresponding minimum variability timescale could be as low as $r_{\rm L}/c \sim 1$ hr for a typical light cylinder radius of $r_{\rm L} \simeq 5 r_{\rm s}$. While efficient electron acceleration appears to be well possible, protons are unlikely to be accelerated into the extreme UHECR regime close to the central black hole. We argue that if Cen A is indeed an extreme UHECR emitting source, then shear acceleration along the kpc-scale jet could represent one of the most promising mechanisms capable of pushing protons up to energies beyond 50 EeV.

Atmospheric blocking in the Australasian region in the Southern Hemisphere winter
Creators: name: Pook, MJ
Publisher: name: University Of Tasmania
Year: 2023

description: Previous studies of blocking in the Australasian region have sought to establish a link between the occurrence of blocking and the observed gradient of sea surface temperature (SST) from the cold waters of the Indian Ocean sector of the Southern Ocean to the relatively warm surface waters to the southeast of Australia. This study investigates the distribution, gradients and seasonal cycles of SST over the Southern Ocean and concludes that the contribution of the west-east gradient in forcing the atmosphere is about an order of magnitude less than the effect of SST gradients in the meridional plane. Furthermore the meridional gradient is magnified during winter because of the interaction of several major influences in the Australian region. These include the significant cooling of the continents of Australia and Antarctica and the configuration of the Antarctic Circumpolar Current (ACC). Where the ACC travels closer to the coast of East Antarctica surface temperature gradients are reinforced aloft by strong meridional temperature gradients induced by the elevated continent. The enhanced westerly thermal wind at high latitudes (south of 50¬¨‚àûS) leads to a westerly wind maximum aloft and the steady cooling of inland Australia acts to weaken the meridional temperature gradient between 30¬¨‚àûS and 45¬¨‚àûS leading to a minimum in the westerly winds in this region. Strong meridional gradients in the north produce an intense westerly thermal wind north of 30¬¨‚àûS. The configuration of mean winds in the middle troposphere is shown to generate positive values of relative vorticity [about 0.1 planetary vorticity] in the south and negative values of similar magnitude over eastern Australia. A prolonged period of blocking in the Australasian region during the winter and early spring of 1989 is investigated in the context of interannual variabilty of blocking frequency. It is postulated that the active monsoon conditions over northern Australia associated with the La Nina of 1988-89 contributed to the lower than normal inland temperatures in the 1989 autumn and the following winter, thus amplifying the cyclonic vorticity generation process over eastern Australia. The enhanced Antarctic polar vortex reported in 1989 is also shown to have contributed to a strengthening of the westerly jet to the south of Australia. The configuration of SST anomalies in the autumn and early winter of 1989 is presented as a significant precursor to the subsequent blocking event. This hypothesis is investigated in a numerical general circulation model of the atmosphere driven by the observed SST anomaly.

description: This resource is a single blog post created as part of the Day of Archaeology initiative. The Day of Archaeology project aimed to provide a window into the daily lives of archaeologists from all over the world. The project asked people working, studying or volunteering in the archaeological world to participate in a 'Day of Archaeology' each year by recording their day and sharing it through text, images or video on the Day of Archaeology blog.
The project asked anyone with a personal, professional or voluntary interest in archaeology to get involved, and help highlight the reasons why archaeology is vital to protect the past and inform our futures. The resulting Day of Archaeology project archive demonstrates the wide variety of work the archaeological profession undertakes day-to-day across the globe, and helps to raise public awareness of the relevance and importance of archaeology to the modern world.
The first ever Day of Archaeology was held in 2011 and, since then, the project had thousands of archaeologists take part in the event, from those working in the field through to specialists working in laboratories and behind computers. The last Day of Archaeology was on Friday 28th July 2017.

description: Magnetic vortex dynamics in lithographically prepared nanodots is currently a subject of intensive research, particularly after recent demonstration that the vortex polarity can be controlled by in-plane magnetic field. This has stimulated the proposals of non-volatile vortex magnetic random access memories. In this work, we demonstrate that triangular nanodots offer a real alternative where vortex chirality, in addition to polarity, can be controlled. In the static regime, we show that vortex chirality can be tailored by applying in-plane magnetic field, which is experimentally imaged by means of Variable-Field Magnetic Force Microscopy. In addition, the polarity can be also controlled by applying a suitable out-of-plane magnetic field component. The experiment and simulations show that to control the vortex polarity, the out-of-plane field component, in this particular case, should be higher than the in-plane nucleation field. Micromagnetic simulations in the dynamical regime show that the magnetic vortex polarity can be changed with short-duration magnetic field pulses, while longer pulses change the vortex chirality.

Palynostratigraphic investigation of upper maastrichtlan and paleocene strata near Tate Lake, N.W.T.
Creators: name: Bihl, Gerhard
Publisher: name: University of British Columbia
Year: 2011

description: Sedimentary strata near Tate Lake, south of Norman Wells, N.W.T., were investigated using palynomorph analysis indicating the presence of Upper Maastrichtian and Paleocene beds. The Upper Maastrichtian sections contain tv/o local palynostratigraphic zones correlative with Srivastava's Wodehousea spinata and Manci-corpus gibbus zones of the Edmonton and Battle Formations of Alberta, and other Maastrichtian formations in western North America. The Paleocene strata compare lithologically and palynologically with the Lower Fort Union Group of Montana and Wyoming, the post-Brazeau beds of the Alberta Foothills, the upper part of the Bonnet Plume Formation, N.W.T., and Tertiary coal deposits in Spitzbergen. A progressive cooling in climate from subtropical to warm temperate during Upper Maastrichtian times is indicated by the decrease in the number of angiosperm species and greater influx of gymnosperms and pteridophytes, A marked change in microflora and lithology at the Cretaceous-Tertiary boundary indicates temperate conditions and increased rates of sedimentation in the Tate Lake area. Major lignite seams characteristic of the Paleocene strata probably were produced in freshwater swamps in one of the subsiding sedimentary basins formed along the east side of the Mackenzie Mountains during the Laramide orogeny. The Tate Lake strata appear to be part of the Hell Creek-Fort Union type formational sequences straddling the Cretaceous-Tertiary boundary indicating that climatic and sedimentary conditions were very similar all along the Rocky Mountains. On this basis corresponding changes are predicted for the Monster, Reindeer and Moose Channel Formations.

description: This paper provides an explicit expression for the capacity region of the two-user broadcast Z channel and proves that the optimal boundary can be achieved by independent encoding of each user. Specifically, the information messages corresponding to each user are encoded independently and the OR of these two encoded streams is transmitted. Nonlinear turbo codes that provide a controlled distribution of ones and zeros are used to demonstrate a low-complexity scheme that operates close to the optimal boundary.

Retrofitting conventional houses inexpensively to improve energy efficiency
Creators: name: Weaver, A
Publisher: name: University Of Tasmania
Year: 2023

description: This research is founded on the notion that energy efficiency should be a standard design characteristic of all housing, and that government action to mandate performance standards for new homes fails to recognize that most people live in existing, often inefficient dwellings. Factors contributing to the nature of existing housing, advantages of energy efficient homes and reasons for the lack of up-take of energy efficiency are investigated. The multi-scalar context for improving existing housing is presented, outlining the international movement towards sustainable development, which embraces sustainable housing and the implicit equity issues of good housing being an essential need for all people, in particular the disadvantaged. The heat transfer principles, techniques and potential benefits of conducting a retrofit to improve the energy efficiency of older conventional housing are researched and a case study retrofit carried out. Four rooms of the study house were monitored for room temperature for one year before the retrofit and then for a further year, and onsite external temperatures were also recorded continuously. Despite some site constraints, including extensive shading of the house, improvements in thermal comfort conditions in the house have been observed, together with a small overall reduction in energy consumption. Most significant were the improvements in the health of family members, especially that of the children, with lower frequencies of ill-health reported and much more rapid recovery times. These findings confirm a growing body of international research linking poor quality housing with higher rates of respiratory and cardiovascular disease and increased winter mortality levels. Traditional cost-benefit assessments of energy efficient retrofits have considered financial and, more recently, environmental factors, but need to be expanded to include the substantial, but difficult to quantify, social gains associated with enhanced quality of living environment and occupant health.
Photovoltaic effect in a gated two-dimensional electron gas in magnetic field

description: The photovoltaic effect induced by terahertz radiation in a gated two-dimensional electron gas in magnetic field is considered theoretically. It is assumed that the incoming radiation creates an ac voltage between the source and gate and that the gate length is long compared to the damping length of plasma waves. In the presence of pronounced Shubnikov-de Haas oscillations, an important source of non-linearity is the oscillating dependence of the mobility on the ac gate voltage. This results in a photoresponse oscillating as a function of magnetic field, which is enhanced in the vicinity of the cyclotron resonance, in accordance with recent experiments. Another, smooth component of the photovoltage, unrelated to SdH oscillations, has a maximum at cyclotron resonance.
