description: We note the possibility to perform a parametrically improved search for gauged baryon ($B$) and baryon minus lepton ($B-L$) Dark Photon Dark Matter (DPDM) using auxiliary channel data from LISA Pathfinder. In particular we use the measurement of the differential movement between the test masses (TMs) and the space craft (SC) which is nearly as sensitive as the tracking between the two TMs. TMs and SC are made from different materials and therefore have different charge-to-mass ratios for both $B-L$ and $B$. Thus, the surrounding DPDM field induces a relative acceleration of nearly constant frequency. For the case of $B-L$, we find that LISA Pathfinder can constrain previously unexplored parameter space, providing the world leading limits in the mass range $4\cdot 10^{-19}\,\text{eV}

description: Driven by the intelligent applications of sixth-generation (6G) mobile communication systems such as smart city and autonomous driving, which connect the physical and cyber space, the integrated sensing and communication (ISAC) brings a revolutionary change to the base stations (BSs) of 6G by integrating radar sensing and communication in the same hardware and wireless resource. However, with the requirements of long-range and accurate sensing in the applications of smart city and autonomous driving, the ISAC enabled single BS still has a limitation in the sensing range and accuracy. With the networked infrastructures of mobile communication systems, multi-BS cooperative sensing is a natural choice satisfying the requirement of long-range and accurate sensing. In this article, the framework of multi-BS cooperative sensing is proposed, breaking through the limitation of single-BS sensing. The enabling technologies, including unified ISAC performance metrics, ISAC signal design and optimization, interference management, cooperative sensing algorithms, are introduced in details. The performance evaluation results are provided to verify the effectiveness of multi-BS cooperative sensing schemes. With ISAC enabled multi-BS cooperative sensing (ISAC-MCS), the intelligent infrastructures connecting physical and cyber space can be established, ushering the era of 6G promoting the intelligence of everything.

Early flood warning system for the Glenmore Reservoir with ANN flow preditions
Creators: name: Yadete, Haimanot A.
Publisher: name: University of Calgary
Year: 2004

description: Bibliography: p. 156-162
description: With the objective of developing an early flood warning system for the Glenmore Reservoir in the Elbow watershed, an Artificial Neural Network (ANN) model was developed to predict streamflows in the Elbow River. Artificial Neural Networks (ANN) provide a potentially useful framework for modelling complex non-linear and dynamic systems, including the complex hydrologic processes that influence stream.flows and flood events. The resulting ANN prediction tool then forms the core of the early flood warning system. Real-time measurements of flows, temperatures and precipitation in the Elbow watershed during preceding days are used as inputs to the prediction model. With the premise that events in a neighbouring waters~ed could potentially trigger a warning, a preliminary correlation analysis was undertaken into the use of available precipitation data for neighbouring watersheds. Either due to low correlation or absence of lag-time with the measured precipitation in the Elbow watershed, this approach for flood warning was abandoned. Precipitation measured in neighbouring watersheds would basically provide limited information on the anticipated precipitation in the Elbow watershed. The optimal ANN model recommended for the early warning system is the result of a thorough investigation of multiple design approaches, including the dual ANN framework. Through the training process of candidate ANN models, the study recognized the shortcomings of the ANN formulation in terms of extrapolating flows beyond the training data sets. The very few peak events available for training, each having different antecedent conditions, also presented difficulties for the ANN, whereby the antecedent space was poorly sampled. To overcome this problem, the study used artificially generated data using the SSARR model already calibrated for the Elbow watershed. The SSARR generated events, together with available measured data, provided a better coverage of the antecedent space. The resulting optimal ANN is capable of forecasting flows up to the 1 in 100 years return period with a maximum error of 16%. Sensitivity analysis of each input parameter proved crucial in the selection of this best model. The development of the ANN model supported the influence of topography on precipitation observed in the correlation analysis of neighbouring watersheds. The prediction capability of the ANN model was significantly improved with the use of multiple gauging stations, rather than relying on the precipitation data gathered at a single location. The core elements of the early warning system attained through this study are improved warning time, prediction of streamflows ( addressed with the ANN model) and the identification of an appropriate action to mitigate the predicted flood event. The study addressed the third element with preliminary reservoir drawdown levels, using the GFlood Program, triggered by the forecasts of the optimal ANN model.

description: In this paper, we consider periodic soft inclusions $T_ε$ with periodicity $ε$, where the solution, $u_ε$, satisfies semi-linear elliptic equations of non-divergence in $Ω_ε=Ω\setminus \bar{T}_ε$ with a Neumann data on $\partial T^{\mathfrak a}$ . The difficulty lies in the non-divergence structure of the operator where the standard energy method based on the divergence theorem can not be applied. The main object is developing a viscosity method to find the homogenized equation satisfied by the limit of $u_ε$, called as $u$, as $ε$ approaches to zero. We introduce the concept of a compatibility condition between the equation and the Neumann condition on the boundary for the existence of uniformly bounded periodic first correctors. The concept of second corrector has been developed to show the limit, $u$, is the viscosity solution of a homogenized equation.

description: Modifications of photoionization arising from resonant electron-electron correlations between neighbouring atoms in an atomic sample are studied. The sample contains atomic species A and B, with the ionization potential of A being smaller than the energy of a dipole-allowed transition in B. The atoms are subject to an external radiation field which is near-resonant with the dipole transition in B. Photoionization of an atom A may thus proceed via a two-step mechanism: photoexcitation in the subsystem of species B, followed by interatomic Coulombic decay. As a basic atomic configuration, we investigate resonant photoionization in a three-atomic system A-B-B, consisting of an atom A and two neighbouring atoms B. It is found that, under suitable conditions, the influence of the neighbouring atoms can strongly affect the photoionization process, including its total probabilty, time development and photoelectron spectra. In particular, by comparing our results with those for photoionization of an isolated atom A and a two-atomic system A-B, respectively, we reveal the characteristic impact exerted by the third atom.

description: Speech Command Recognition (SCR), which deals with identification of short uttered speech commands, is crucial for various applications, including IoT devices and assistive technology. Despite the promise shown by Convolutional Neural Networks (CNNs) in SCR tasks, their efficacy relies heavily on hyper-parameter selection, which is typically laborious and time-consuming when done manually. This paper introduces a hyper-parameter selection method for CNNs based on the Differential Evolution (DE) algorithm, aiming to enhance performance in SCR tasks. Training and testing with the Google Speech Command (GSC) dataset, the proposed approach showed effectiveness in classifying speech commands. Moreover, a comparative analysis with Genetic Algorithm based selections and other deep CNN (DCNN) models highlighted the efficiency of the proposed DE algorithm in hyper-parameter selection for CNNs in SCR tasks.

description: Wigner's seminal work on the Poincaré group revealed one of the fundamental principles of quantum theory: symmetry groups are projectively represented. The condensed-matter counterparts of the Poincaré group could be the spacetime groups of periodically driven crystals or spacetime crystals featuring spacetime periodicity. In this study, we establish the general theory of projective spacetime symmetry algebras of spacetime crystals, and reveal their intrinsic connections to gauge structures. As important applications, we exhaustively classify (1,1)D projective symmetry algebras and systematically construct spacetime lattice models for them all. Additionally, we present three consequences of projective spacetime symmetry that surpass ordinary theory: the electric Floquet-Bloch theorem, Kramers-like degeneracy of spinless Floquet crystals, and symmetry-enforced crossings in the Hamiltonian spectral flows. Our work provides both theoretical and experimental foundations to explore novel physics protected by projective spacetime symmetry of spacetime crystals.
Projecting human development and CO2 emissions

description: We estimate cumulative CO2 emissions during the period 2000 to 2050 from developed and developing countries based on the empirical relationship between CO2 per capita emissions (due to fossil fuel combustion and cement production) and corresponding HDI. In order to project per capita emissions of individual countries we make three assumptions which are detailed below. First, we use logistic regressions to fit and extrapolate the HDI on a country level as a function of time. This is mainly motivated by the fact that the HDI is bounded between 0 and 1 and that it decelerates as it approaches 1. Second, we employ for individual countries the correlations between CO2 per capita emissions and HDI in order to extrapolate their emissions. This is an ergodic assumption. Third, we let countries with incomplete data records evolve similarly as their close neighbors (in the emissions-HDI plane, see Fig. 1 in the main text) with complete time series of CO2 per capita emissions and HDI. Country-based emissions estimates are obtained by multiplying extrapolated CO2 per capita values by population numbers of three scenarios extracted from the Millennium Ecosystem Assessment report. Finally, we propose a reduction scheme, where countries with an HDI above the development threshold reduce their per capita CO2 emissions with a rate that is proportional to their HDI. We estimate the minimum proportionality constant so that the global emissions by 2050 meet the 1000Gt limit.

The effects of genotoxic stress on the p53/p21wafl/cip1 response
Creators: name: Bodzak, Ewelina
Publisher: name: University of Calgary
Year: 2004

description: Bibliography: p. 190-214
description: The p53 tumor suppressor protein is the central component of the cellular response to genotoxic stress. Due to the prevalence of p53 mutations in numerous human cancers, the study of the activation, and function of this protein is critical to understanding the mechanisms underlying cellular proliferation, and growth. The critical role of p53 hinges on its capacity to integrate signals from different stress induced pathways, and coordinate protective measures resulting in arrest, repair, or apoptosis. Primarily, p53 functions in the expression of genes, and though it can participate in transcription independent interactions, the most common indicator of p53 activity is the upregulation of the p2iwafl/cipl target protein (heretofore referred to as p21). p21 has been established as a hallmark of p53 functioning, and as a direct consequence of p53 transcriptional activity, in response to stress. p21 functions as a positive and negative regulator of cellular progression, and has a role in both Gi and G2 arrest, repair, and apoptosis. It is widely accepted that though signal transduction to p53, is dependent on the nature of stress, the subsequent functioning of the tumor suppressor, in the upregulation of target proteins, such as p21, is comparable and independent of the specific genotoxic stressor. In the present study, the classic p53/p21 paradigm is re-examined in response to differing genotoxic stressors, in normal human lymphoblasts. The results presented within this dissertation demonstrate that p53 transcriptional activation of p21 is specific to type of stress. Furthermore, despite comparable activation, p53 can discriminate between promoters depending on the nature of stress. Moreover, p53 promoter occupancy has direct consequences on histone acetylation, and target gene expression. Importantly, the effect of the differential expression, has consequences on the cellular outcome. The findings presented here demonstrate that the nature of genotoxic stress has a distinct impact on the p53/p21 response in normal human cells, and may be a mechanism underlying p53's role in determining the cellular outcome. The differential p53 transcriptional activity observed in these cells, has implications on the treatment of hematopoietic cancers, and provides an attractive model system for further study of p53 and p21 functions.
An integrated predictive vegetation modelling approach: combining remote sensing, GIS, and biological theory
Creators: name: Yuen, Jeffrey Lin
Publisher: name: University of Calgary
Year: 2004

description: Bibliography: p. 53-59
description: Many diverse approaches have developed in order to characterize the spatial distribution of landscape features (particularly vegetation pattern). While technically variable, the data used in landscape characterization can be assigned into one of two categories - those that are spectrally derived from remotely sensed data and those that are ecologically relevant resource gradients. The remote sensing approach uses empirical relationships between land cover classes and spectral reflectance to classify a landscape, whereas the biological approach uses physiological and ecological relationships in defining geographic suitability for different species. Remote sensing approaches are limited in their ability to distinguish vegetation classes at the species scale, while biological approaches are limited in their ability to identify nonvegetated features on the landscape. In this thesis, an integrated method that combines these complimentary approaches is developed and compared to the individual spectral and biological approaches. The result is an accurate land cover pattern distribution that is able to resolve tree cover at the species level, while retaining the ability to define disturbed and non-vegetated areas.

description: Since the seminal work of [9] and their Physics-Informed neural networks (PINNs), many efforts have been conducted towards solving partial differential equations (PDEs) with Deep Learning models. However, some challenges remain, for instance the extension of such models to complex three-dimensional geometries, and a study on how such approaches could be combined to classical numerical solvers. In this work, we justify the use of graph neural networks for these problems, based on the similarity between these architectures and the meshes used in traditional numerical techniques for solving partial differential equations. After proving an issue with the Physics-Informed framework for complex geometries, during the computation of PDE residuals, an alternative procedure is proposed, by combining classical numerical solvers and the Physics-Informed framework. Finally, we propose an implementation of this approach, that we test on a three-dimensional problem on an irregular geometry.

Perspectives to enhance the superconducting transition temperature are discussed.

Risk allocation in contracts: how to improve the process

Publisher: name: University of Calgary
Year: 2005

description: Bibliography: p. 209-232
description: Recent research and industry experts have indicated that inappropriate risk allocation through disclaimer clauses in contracts is a significant reason for increasing the total cost of a project. Most literature and studies on this topic suggest solutions for the symptoms to the problem but they do not address the root cause. Furthermore, most of these studies are in industries other than construction. However, those in construction do not go beyond single case studies or formulas and advice, which are based on having been more successful in practice, rather than a careful empirical research. The objectives of this research were to test the current practice of risk allocation in the construction industry, uncover the rationale behind inappropriate risk allocation through the use of disclaimer clauses, and identify methods by which to overcome this rationale and improve the whole process. Thus, this research was based on a quantitative-qualitative triangulation methodology approach, consisting of three phases in parallel with the literature review. Phase one of this research was a quantitative section based on a mail-out survey across Canada. Phase two was a qualitative section based on a Modified Delphi questionnaire with a panel of experts. Phase three was a qualitative Modified Grounded Theory interviews based on the results that were analysed from the previous phases. The results of this research identified that using disclaimer clause to allocate risk is a common industry practice, validated the amount of premiums attached to the fi most common disclaimer clause in construction contracts, uncovered the rationale of using disclaimer clauses to allocate risks and recognized the relationship between trust and better risk allocation process in construction contracts. Additionally, this research presented a unique i w which is based on empirical research that proposes a risk allocation framework based on trust relation hip between the contracting parties to improve general business environment and reduce the total project cost in the Canadian construction industry.

description: En las infracciones de las prohibiciones antitrust con pluralidad de partícipes la identificación del daño y su secuencia de producción causal serán determinantes en la determinación del perímetro de responsabilidad solidaria entre los co-infractores por los daños causados. Aunque una eventual decisión previa de la infracción por la autoridad de competencia proporciona un presupuesto fáctico y jurídico que el juez civil no puede ignorar, la caracterización de la conducta infractora como una “infracción única y continuada” no se traducirá necesariamente en que la responsabilidad solidaria de quienes participaron en ella. Corresponde al juez civil comprobar si la infracción produjo daño e indagar sobre el nexo de causalidad entre las conductas infractoras y los eventuales perjuicios.
 La responsabilidad solidaria de los co-infractores sirve a los objetivos de tutelar el derecho de los perjudicados a obtener una compensación y de disuadir la participación en las conductas prohibidas, pero su fundamentación requiere la concurrencia causal de la conducta de una pluralidad de sujetos; de modo que la solidaridad no opera cuando puedan identificarse daños e itinerarios de producción causal distintos a partir de conductas que puedan diferenciarse. En cambio, las posibles variaciones en la intensidad de la conducta infractora de cada co-partícipe en la infracción -y, por ende, de su contribución al daño- no excluyen su responsabilidad solidaria frente a los perjudicados, aunque sea determinante del ulterior reparto en las eventuales acciones de repetición entre los co-inftractores.

description: Super-hot looptop sources, detected in some large solar flares, are compact sources of HXR emission with spectra matching thermal electron populations exceeding 30 megakelvins. High observed emission measure, as well as inference of electron thermalization within the small source region, both provide evidence of high densities at the looptop; typically more than an order of magnitude above ambient. Where some investigators have suggested such density enhancement results from a rapid enhancement in the magnetic field strength, we propose an alternative model, based on Petschek reconnection, whereby looptop plasma is heated and compressed by slow magnetosonic shocks generated self-consistently through flux retraction following reconnection. Under steady conditions such shocks can enhance density by no more than a factor of four. These steady shock relations (Rankine-Hugoniot relations) turn out to be inapplicable to Petschek's model owing to transient effects of thermal conduction. The actual density enhancement can in fact exceed a factor of ten over the entire reconnection outflow. An ensemble of flux tubes retracting following reconnection at an ensemble of distinct sites will have a collective emission measure proportional to the rate of flux tube production. This rate, distinct from the local reconnection rate within a single tube, can be measured separately through flare ribbon motion. Typical flux transfer rates and loop parameters yield emission measures comparable to those observed in super-hot sources.

description: Rigorous analytical techniques are combined with phylogeneticsystematic methodology to provide a new perspective on the scientific informativeness of the eggs and eggshells of both extant and extinct dinosaurs. Re-description of the eggs of paleognathous birds reveals that numerous eggshell characteristics were overlooked by previous investigators. A cladistic analysis of discrete egg characters of paleognaths reveals that although trees based on egg data provide less resolution among taxa than those based on skeletal data, egg data do provide phylogenetic information and can help resolve disagreements in relationships derived from skeletal data. In an analysis based on the egg data alone, tinamous are basal among paleognaths, Apteryx is basal among ratites and the sister taxon of an unresolved clade consisting of large ratites, within which Aepyornis and dinornithids form a subclade and Casuarius and Dromaius form a subclade. When the egg data are combined with the skeletal data of Bledsoe (1988), the clade of Apteryx, Casuarius, and Dromaius is dissolved, and Apteryx moves to a basal position within Ratitae. Analysis of 13 absolute measurements and ratios from the eggs reveals that only 4 of these continuous characters are suitable for cladistic analysis. A cladistic analysis of the continuous and discrete characters provides further resolution among taxa within the tree based on egg data in that Struthio and Rhea form a clade. Fossil eggs of several dinosaurs (including birds) are described and included in a cladistic analysis of 24 ootaxa, the results of which, in general, are comparable to those drawn from skeletal-based studies. Sauropod eggs are basal in Saurischia, allosauroid eggs are basal in Theropoda, the eggs of oviraptorids and dromaeosaurids form a derived clade, and the eggs of troodontids and birds form a clade. Unexpected results include the basal position of therizinosaurid eggs, a clade consisting of Protoceratopsidovum (Protoceratops eggs) and troodontid eggs, and a clade consisting of Deinonychus and oviraptorid eggs. These anomalies may call the alleged parentage of these eggs into question. The evolutionary-systematic method that was used to construct the traditional parataxonomic system for fossil eggs is eschewed, and a new nomenclatural system employing a phylogenetic-systematic methodology is proposed. Phylogenetic definitions are erected for seven ooclades of Saurischia, following the tenets of phylogenetic nomenclature.

description: In this paper, using the latest Pantheon+ sample of Type Ia supernovae (SNe Ia), Baryon Acoustic Oscillation (BAO) measurements, and observational Hubble data (OHD), we carry out a joint constraint on the Hubble constant $H_0$, the spatial curvature $Ω_{\rm K}$, and the sound horizon at the end of drag epoch $r_{\rm d}$. To be model-independent, four cosmography models, i.e., the Taylor series in terms of redshift $y_1=z/(1+z)$, $y_2=\arctan(z)$, $y_3=\ln(1+z)$, and the Padé approximants, are used without the assumption of flat Universe. The results show that the $H_0$ is anti-correlated with $Ω_{\rm K}$ and $r_{\rm d}$, indicating smaller $Ω_{\rm K}$ or $r_{\rm d}$ would be helpful in alleviating the Hubble tension. And the values of $H_0$ and $r_{\rm d}$ are consistent with the estimate derived from the Planck Cosmic Microwave Background (CMB) data based on the flat $Λ$CDM model, but $H_0$ is in 2.3$\sim$3.0$σ$ tension with that obtained by \cite{Riess2022} in all these cosmographic approaches. Meanwhile, a flat Universe is preferred by the present observations under all approximations except the third order of $y_1$ and $y_2$ of the Taylor series. Furthermore, according to the values of the Bayesian evidence, we found that the flat $Λ$CDM remains to be the most favored model by the joint datasets, and the Padé approximant of order (2,2), the third order of $y_3$ and $y_1$ are the top three cosmographic expansions that fit the datasets best, while the Taylor series in terms of $y_2$ are essentially ruled out.

description: This paper deals with the identification of Multiword Expressions (MWEs) in Manipuri, a highly agglutinative Indian Language. Manipuri is listed in the Eight Schedule of Indian Constitution. MWE plays an important role in the applications of Natural Language Processing(NLP) like Machine Translation, Part of Speech tagging, Information Retrieval, Question Answering etc. Feature selection is an important factor in the recognition of Manipuri MWEs using Conditional Random Field (CRF). The disadvantage of manual selection and choosing of the appropriate features for running CRF motivates us to think of Genetic Algorithm (GA). Using GA we are able to find the optimal features to run the CRF. We have tried with fifty generations in feature selection along with three fold cross validation as fitness function. This model demonstrated the Recall (R) of 64.08%, Precision (P) of 86.84% and F-measure (F) of 73.74%, showing an improvement over the CRF based Manipuri MWE identification without GA application.

Event-Triggered Consensus for Continuous-Time Distributed Estimation

description: Distributed sensor networks have gained interest thanks to the developments in processing power and communications. Event-triggering mechanisms can be useful in reducing communication between the nodes of the network, while still ensuring an adequate behaviour of the system. However, very little attention has been given to continuous-time systems in this context. In this work, we propose a strategy for distributed state estimation in sensor networks, based on average dynamic consensus of the continuous measurements. While communication between nodes is discrete and heavily reduced due to the event-triggering mechanism, our method ensures that the nodes are still able to produce a continuous estimate of the global average measurement and the state of the plant, within some tuneable error bounds.

description: Src family kinases were first identified as transforming alleles captured in the genome of retroviruses almost three decades ago. These tyrosine kinases integrate and relay information to negotiate appropriate biological outcomes in response to a multitude of extracellular cues. Their inappropriate activation has been associated with a number of pathophysiologies, including cancer, autoimmune, and inflammatory diseases. Therefore, strict spatiotemporal control of these kinases is vital for the maintenance of cellular homeostasis and tissue integrity. However, very little is known with respect to the normal signalling pathways with which they serve. The overriding theme of this thesis was to describe and dissect the elaborate circuitry within which these kinases act, in order to enhance our understanding of Src family biology. Hematopoietic cell kinase (Hck) is one such Src family kinase that is expressed in the myelomonocytic lineage and B-cells. In these cells, Hck serves multiple signalling capacities, and its deregulation has been implicated in several disease states. In the current study, the signalling networks involving Hck are investigated. Using GST-Hck fusion constructs, the association of this kinase with numerous signalling molecules in unstimulated and activated hematopoietic cells was established. This led to the biochemical characterization of a tyrosine kinase activity likely corresponding to Syk; a novel putative effector of Hck; the c-cbl proto-oncogene product; and a novel, transfonning mutant of c-Cbl, termed p95Cbl. Protein ubiquitination has emerged as an important regulatory modification in diverse cellular processes, including tyrosine kinase signalling. c-Cbl acts as an adaptor protein and as an E3 ubiquitin ligase, directing ubiquitination and the ensuing destruction protein and as an E3 ubiquitin ligase, directing ubiquitination and the ensuing destruction of signalling molecules. This investigation also includes the detailed characterization of the herein identified p95Cbl mutant, which was found to harbour an internal deletion removing the RING fmger, thus crippling its ubiquitin ligase activity, while retaining all of its protein-protein interaction domains. p95Cbl displays aberrant subcellular localization and tyrosine phosphorylation, and potently transforms NIH3T3 fibroblasts and BalF3 hematopoietic cells in culture. In addition, a pronounced, selective sensitivity of mutant c-Cbl proteins to the antileukemic compound piceatannol was observed, thus demarcating c-Cbl mutants as potential therapeutic targets. A possibility for alterations to c-Cbl in human malignancies is discussed.

description: Optimally-doped La1.85Sr0.15CuO4 single crystals have been investigated by dc and ac magnetic measurements. These crystals have rectangular needle-like shapes with the long needle axis parallel to the crystallographic c axis (c-crystal) or parallel to the basal planes (a-crystal). In both crystals, the temperature dependence of the upper critical fields (HC2) and the surface critical field (HC3) were measured. The H-T phase diagram is presented. Close to TC =35 K, for the c-crystal, γc = / = 1.80(2), whereas for the a-crystal the γa = / =4.0(2) obtained, is much higher than the theoretical value 1.69. At low applied dc fields, positive field-cooled branches known as the "paramagnetic Meissner effect" (PME) are observed, their magnitude is inversely proportional to H. The anisotropic PME is observed in both a- and c-crystals, only when the applied field is along the basal planes. It is speculated that the high γa and the PME are connected to each other.

description: We evaluate the average and the standard deviation of the supercurrent in superconducting nanobridges, as functions of the temperature and the phase difference, in an equilibrium situation. We also evaluate the autocorrelation of the supercurrent as a function of the elapsed time. The behavior of supercurrent fluctuations is qualitatively different from from that of the normal current: they depend on the phase difference, have a different temperature dependence, and for appropriate range their standard deviation is independent of the probing time. We considered two radically different filaments and obtained very similar results for both. Fluctuations of the supercurrent can in principle be measured.

description: Let $\mathbb K$ be a field of characteristic 0. Let $Γ\subset\mathbb P^n_{\mathbb K}$ be a reduced finite set of points, not all contained in a hyperplane. Let $hyp(Γ)$ be the maximum number of points of $Γ$ contained in any hyperplane, and let $d(Γ)=|Γ|-hyp(Γ)$. If $I\subset R=\mathbb K[x_0,...,x_n]$ is the ideal of $Γ$, then in \cite{t1} it is shown that for $n=2,3$, $d(Γ)$ has a lower bound expressed in terms of some shift in the graded minimal free resolution of $R/I$. In these notes we show that this behavior is true in general, for any $n\geq 2$: $d(Γ)\geq A_n$, where $A_n=\min\{a_i-n\}$ and $\oplus_i R(-a_i)$ is the last module in the graded minimal free resolution of $R/I$. In the end we also prove that this bound is sharp for a whole class of examples due to Juan Migliore (\cite{m}).
