description: The Eastern Tianshan Orogen (Xinjiang, NW China) in the Central Asian Orogenic Belt (CAOB) is featured by its many Carboniferous-Triassic mafic-ultramafic intrusions and associated magmatic Fe-Ti-V oxide mineralization. In this study, we present the first systematic data comparison on the age and whole-rock geochemistry of the ore-forming mafic-ultramafic complexes at Yaxi, Niumaoquan, Xiangshanxi, and Weiya. Our new age dating on the Yaxi complex indicates that the mineralized gabbro (zircon SHRIMP U-Pb dated 297.3 ± 4.9 Ma) formed in the latest Carboniferous-Early Permian, similar to the diorite (LA-ICP-MS zircon U-Pb dated 308.3 ± 8.6 Ma) and granodiorite (LA-ICP-MS zircon U-Pb dated 304.9 ± 1.7 Ma). The Yaxi complex is the oldest late Palaeozoic mafic-ultramafic intrusion reported so far in the Eastern Tianshan. The mineralized gabbro at Yaxi contains higher average Fe2O3T (20.83 wt.%), TiO2 (5.91 wt.%), and V (523 ppm) contents than its ore-barren counterpart (7.45 wt.%, 0.99 wt.%, and 133 ppm, respectively). These Eastern Tianshan mafic rocks are mildly large ion lithophile element (LILE) enriched and high field-strength element (HFSE) depleted, and with LREE/HREE enrichment (Yaxi: (La/Yb)N = 2.7 ~ 5.37) and subtle positive Eu anomalies (Yaxi: Eu/Eu* = 0.94 to 3.31). This suggests that the Eastern Tianshan mafic-ultramafic magmas were likely derived from an arc/subduction-modified magma source. The E-W trending crustal-scale faults (e.g. the Aqikkuduk fault) may have acted as magma conduits and controlled the magma emplacement. The spatial-temporal distribution of the Eastern Tianshan Fe-Ti-V ore-forming mafic-ultramafic complexes and their petrologic and geochemical features suggest that the latest Carboniferous-Early Permian magmatic phase was likely emplaced in a collision-related compression setting following the Junggar Ocean closure, whereas the late Early Permian phase may have been related to a post-collisional orogenic setting.

description: The fundamental problem of the occurrence/removal of finite-time future singularity in the universe evolution for coupled dark energy (DE) is addressed. It is demonstrated the existence of the (instable or local minimum) de Sitter space solution which may cure the Type II or Type IV future singularity for DE coupled with DM as the result of tuning the initial conditions. In case of phantom DE, the corresponding coupling may help to resolve the coincidence problem but not the Big Rip (Type I) singularity issue. We show that modified gravity of special form or inhomogeneous DE fluid may offer the universal scenario to cure the Type I,II,III or IV future singularity of coupled (fluid or scalar) DE evolution.

Revisiting Gradient Clipping: Stochastic bias and tight convergence guarantees
Creators: name: Koloskova, Anastasia

Publisher: name: CISPA
Year: 2023

description: Gradient clipping is a popular modification to standard (stochastic) gradient descent, at every iteration limiting the gradient norm to a certain value
. It is widely used for example for stabilizing the training of deep learning models (Goodfellow et al., 2016), or for enforcing differential privacy (Abadi et al., 2016). Despite popularity and simplicity of the clipping mechanism, its convergence guarantees often require specific values of
 and strong noise assumptions. In this paper, we give convergence guarantees that show precise dependence on arbitrary clipping thresholds
 and show that our guarantees are tight with both deterministic and stochastic gradients. In particular, we show that (i) for deterministic gradient descent, the clipping threshold only affects the higher-order terms of convergence, (ii) in the stochastic setting convergence to the true optimum cannot be guaranteed under the standard noise assumption, even under arbitrary small step-sizes. We give matching upper and lower bounds for convergence of the gradient norm when running clipped SGD, and illustrate these results with experiments.

description: The polarized Raman scattering spectra of nonsuperconducting $α$-FeTe and of the newly discovered, As-free superconductor Fe$_{1.03}$Se$_{0.3}$Te$_{0.7}$ are measured at room temperature on single crystals. The phonon modes are assigned by combining symmetry analysis with first-principles calculations. In the parent compound $α$-FeTe, the A$_{1g}$ mode of the Te atom and the B$_{1g}$ mode of the Fe atom are observed clearly, while in superconducting Fe$_{1.03}$Se$_{0.3}$Te$_{0.7}$, only a softened Fe B$_{1g}$ mode can be seen. No electron-phonon coupling feature can be distinguished in the spectra of the two samples. By contrast, the spectra of the superconducting system show a slight enhancement below 300$cm^{-1}$, which may be of electronic origin.

Special Properties of Gradient Descent with Large Learning Rates

description: When training neural networks, it has been widely observed that a large step size is essential in stochastic gradient descent (SGD) for obtaining superior models. However, the effect of large step sizes on the success of SGD is not well understood theoretically. Several previous works have attributed this success to the stochastic noise present in SGD. However, we show through a novel set of experiments that the stochastic noise is not sufficient to explain good non-convex training, and that instead the effect of a large learning rate itself is essential for obtaining best performance.We demonstrate the same effects also in the noise-less case, i.e. for full-batch GD. We formally prove that GD with large step size ---on certain non-convex function classes --- follows a different trajectory than GD with a small step size, which can lead to convergence to a global minimum instead of a local one. Our settings provide a framework for future analysis which allows comparing algorithms based on behaviors that can not be observed in the traditional settings.

description: This report covers the research undertaken in the Papua New Guinea highlands as part of the much larger project, Do No Harm: Understanding the Relationship between Women’s Economic Empowerment and Violence against Women in Melanesia. The Do No Harm (DNH) research addresses the question of how to improve women’s economic agency and the security of their livelihoods without compromising their safety. It sought to capture the diversity of ways that women endeavour to overcome economic disadvantage in contemporary Melanesia. Fieldwork for the Do No Harm research was undertaken in Solomon Islands and Papua New Guinea, with a total of 485 interviews conducted, including 238 with women.1 The interviews generated a large body of rich qualitative data on women’s lives and the difficulties and challenges they confront as they seek to earn income in order to improve their lives and those of their children.

description: We study the spin-dependent electronic excitations in alkali-metal nanoparticles. Using numerical and analytical approaches, we focus on the resonances in the response to spin-dependent dipole fields. In the spin-dipole absorption spectrum for closed-shell systems, we investigate in detail the lowest-energy excitation, the "surface paramagnon" predicted by L. Serra et al. [Phys. Rev. A 47, R1601 (1993)]. We estimate its frequency from simple assumptions for the dynamical magnetization density. In addition, we numerically determine the dynamical magnetization density for all low-energy spin-dipole modes in the spectrum. Those many-body excitations can be traced back to particle-hole excitations of the noninteracting system. Thus, we argue that the spin-dipole modes are not of collective nature. In open-shell systems, the spin-dipole response to an electrical dipole field is found to increase proportionally with the ground-state spin polarization.

The role of anxiety in school achievement
Creators: name: Farmer, Ruth Alfreda
Publisher: name: University of British Columbia
Year: 2011

description: Matched groups of Grade VI pupils obtaining low, medium, and high scores on the Test Anxiety Scale for Children were compared on the basis of their performances on four school examinations to determine the extent and nature of the relationship between anxiety and school achievement. Analyses were made of the data pertaining to the performances of the boys and girls together, and of the boys and girls separately, on the four examinations, combined, and on each individual examination. Out of a total of 45 possible differences 6 were found to be statistically significant. Results for the girls were negative throughout but medium-anxious boys were found to do less well than their low- and high-anxious mates on two of the four examinations. Groups of boys and girls together showed differences similar to the boys. Statistically significant differences pointed to a “U" type curvilinear relationship between anxiety and performance. An analysis was also made of the power of each of the items on the anxiety scale to discriminate between high- and low-achievers. Twenty-nine of the total of 30 test items failed to discriminate in a statistically significant way between high- and low-achievers. Findings suggest limitations to the use of individual anxiety scores for interpretive or predictive purposes without further investigation. Revisions of a procedural nature were suggested as possible means of increasing the likelihood of obtaining more meaningful results from an investigation into the effects of anxiety on performance.

Sh2-205: II. Its quiescent stellar formation activity

description: We present a study of active stellar forming regions in the environs of the HII region Sh2-205. The analysis is based on data obtained from point source catalogues and images extracted from 2MASS, MSX, and IRAS surveys. Complementary data are taken from CO survey. The identification of primary candidates to stellar formation activity is made following colour criteria and the correlation with molecular gas emission. A number of stellar formation tracer candidates are projected on two substructures of the HII region: SH148.83-0.67 and SH149.25-0.00. However, the lack of molecular gas related to these structures casts doubts on the nature of the sources. Additional infrared sources may be associated with the HI shell centered at (l,b) = (149\degr 0\arcmin, -1\degr 30\arcmin). The most striking active area was found in connection to the HII region LBN 148.11-0.45, where stellar formation candidates are projected onto molecular gas. The analytical model to the "collect and collapse" process shows that stellar formation activity could have been triggered by the expansion of this HII region.

description: Data heterogeneity across clients is a key challenge in federated learning. Prior works address this by either aligning client and server models or using control variates to correct client model drift. Although these methods achieve fast convergence in convex or simple non-convex problems, the performance in over-parameterized models such as deep neural networks is lacking. In this paper, we first revisit the widely used FedAvg algorithm in a deep neural network to understand how data heterogeneity influences the gradient updates across the neural network layers. We observe that while the feature extraction layers are learned efficiently by FedAvg, the substantial diversity of the final classification layers across clients impedes the performance. Motivated by this, we propose to correct model drift by variance reduction only on the final layers. We demonstrate that this significantly outperforms existing benchmarks at a similar or lower communication cost. We furthermore provide proof for the convergence rate of our algorithm.

description: In order to study the vortex pinning determined by artificially introduced pinning centers in the small-vortex displacement regime, we measured the microwave surface impedance at 47.7 GHz in the mixed state of YBa$_{2}$Cu$_{3}$O$_{7-δ}$ thin films, where sub-micrometric BaZrO$_3$ particles have been incorporated. As a function of the BaZrO$_3$ content, we observe that the absolute losses slightly decrease up to a BaZrO$_3$ content of 5%, and then increase. We found that the magnetic-field-induced losses behave differently, in that they are not monotonic with increasing BaZrO$_3$ concentration: at small concentration (2.5%) the field-induced losses increase, but large reduction of the losses themselves, by factors up to 3, is observed upon further increasing the BaZrO$_3$ concentration in the target up to 7%. Using measurements of both surface resistance and surface reactance we estimate vortex pinning-related parameters. We find that BaZrO$_3$ inclusions introduce deep and steep pinning wells. In particular, the minimum height of the energy barrier for single vortices is raised. At larger BaZrO$_3$ content (5% and 7%) the phenomenon is at its maximum, but it is unclear whether it shows a saturation or not, thus leaving room for further improvements.

description: Wood is a prototypical biological material, which adapts to mechanical requirements. The microarchitecture of cellulose fibrils determines the mechanical properties of woody materials, as well as their actuation properties, based on absorption and desorption of water. Herein it is argued that cellulose fiber orientation corresponds to an analog code that determines the response of wood to humidity as an active material. Examples for the harvesting of wood activity, as well as bioinspiration, are given.

description: We study a landscape of four-dimensional $\mathcal{N}=1$ superconformal field theories (SCFTs) with identical central charges. These theories are obtained by renormalization group flows triggered by supersymmetry-preserving superpotential deformations of the $\mathcal{N}=1$ gauging of the flavor symmetry of a collection of $\mathcal{N}=2$$\mathcal{D}_p(G)$ Argyres--Douglas SCFTs. In this work, we focus on the fixed points in the landscape of the $SU(3)$ gauging of three copies of the $\mathcal{D}_2(SU(3)) = H_2$ theory together with an adjoint-valued chiral multiplet. We catalogue the network of $a = c$ fixed points, and, along the way, we find a variety of dualities and instances of supersymmetry enhancement.

Admissions policy for an institution for the senile: a study of formal and informal criteria for admission to Valleyview Hospital, Essondale, B.C., 1960-61
Creators: name: MacLean, Jean Ethel
Publisher: name: University of British Columbia
Year: 2011

description: Programs and facilities necessary for the proper care and treatment of the senile are many and varied. This study is concerned with one of the institutional resources: the policies and procedures governing admission to Valleyview Hospital, an institution designed specifically for the aged with other disabilities of senility. To apply "operational" tests to policy and procedure, a sample of (30) applicants from the waiting list were selected for study, the purposes being (a) to determine what factors were operative in securing admission, (b) how the stated criteria for assessing priority of admission were utilized. A number of special personal circumstances affected the appropriateness of the group. Apart from this, it was found that the formal criteria for acceptance of applications to the hospital are employed with reasonable consistency, when measured against the time an individual applicant spends on the waiting list. It was also found that when a community agency initiated the application, admission was granted after relatively short periods on the waiting list, if there was no other resource readily available. Prom this study, the roles of the social worker in pre-admission services can be delineated as (a) helping the applicant to find other forms of care over the waiting period, (b) helping the Medical Superintendent to assess priorities for admission, and (c) helping applicants and families to accept the need for hospitalization when this is justifiable. Recommendations for needed changes in procedures and in legislation are made, particularly in the present cumbersome application arrangements, which require certification of the applicant as mentally ill before an application can he placed on the waiting list. Development in the community of specialized types of boarding and nursing homes for the care of the less severely handicapped by emotional and behavioural disturbances is also recommended.

description: We address the system-size dependence of typical plastic flow events when an amorphous solid is put under a fixed external strain rate at a finite temperature. For system sizes that are accessible to numerical simulations at reasonable strain rates and at low temperatures the magnitude of plastic events grows with the system size. We explain however that this must be a finite size effect; for larger systems there exist two cross-over length-scales $ξ_1$ and $ξ_2$, the first determined by the elastic time-scale and the second by the thermal energy-scale. For system of linear size $L$ larger than any of these scales the magnitude of plastic events must be bounded. For systems of size $L\gg ξ$ there must exist $(L/ξ)^d$ uncorrelated plastic events which occur simultaneously. We present a scaling theory that culminates with the dependence of the cross-over scales on temperature and strain rate. Finally we relate these findings to the temperature and size dependence of the stress fluctuations. We comment on the importance of these considerations for theories of elasto-plasticity.

We investigate how the loss of teleportation fidelity resulting for the use of non-orthogonal states compares to a similar loss of fidelity when noisy or non-maximally entangled states as used as teleportation resource. Our analysis leads to certain interesting results on the teleportation efficiency of both pure and mixed non-orthgonal states compared to that of non-maximally entangled and mixed states.

description: We explore consistency among different distance measures, including Supernovae Type Ia data, measurements of the Hubble parameter, and determination of the Baryon acoustic oscillation scale. We present new constraints on the cosmic transparency combining $H(z)$ data together with the latest Supernova Type Ia data compilation. This combination, in the context of a flat $Λ$CDM model, improves current constraints by nearly an order of magnitude. We re-examine the recently reported tension between the Baryon acoustic oscillation scale and Supernovae data in light of possible deviations from transparency, concluding that the source of the discrepancy may most likely be found among systematic effects of the modelling of the low redshift data or a simple $\sim 2-σ$ statistical fluke, rather than in exotic physics. Finally, we attempt to draw model-independent conclusions about the recent accelerated expansion, determining the acceleration redshift to be $z_{acc}=0.35^{+0.20}_{-0.13}$ (1-$σ$).

description: Let $(X,Y)$ be a random couple in $S\times T$ with unknown distribution $P$ and $(X_1,Y_1),...,(X_n,Y_n)$ be i.i.d. copies of $(X,Y).$ Denote $P_n$ the empirical distribution of $(X_1,Y_1),...,(X_n,Y_n).$ Let $h_1,...,h_N:S\mapsto [-1,1]$ be a dictionary that consists of $N$ functions. For $λ\in {\mathbb{R}}^N,$ denote $f_λ:=\sum_{j=1}^Nλ_jh_j.$ Let $\ell:T\times {\mathbb{R}}\mapsto {\mathbb{R}}$ be a given loss function and suppose it is convex with respect to the second variable. Let $(\ell \bullet f)(x,y):=\ell(y;f(x)).$ Finally, let $Λ\subset {\mathbb{R}}^N$ be the simplex of all probability distributions on $\{1,...,N\}.$ Consider the following penalized empirical risk minimization problem \begin{eqnarray*}\hatλ^{\varepsilon}:={\mathop {argmin}_{λ\in Λ}}\Biggl[P_n(\ell \bullet f_λ)+\varepsilon \sum_{j=1}^Nλ_j\log λ_j\Biggr]\end{eqnarray*} along with its distribution dependent version \begin{eqnarray*}λ^{\varepsilon}:={\mathop {argmin}_{λ\in Λ}}\Biggl[P(\ell \bullet f_λ)+\varepsilon \sum_{j=1}^Nλ_j\log λ_j\Biggr],\end{eqnarray*} where $\varepsilon\geq 0$ is a regularization parameter. It is proved that the ``approximate sparsity'' of $λ^{\varepsilon}$ implies the ``approximate sparsity'' of $\hatλ^{\varepsilon}$ and the impact of ``sparsity'' on bounding the excess risk of the empirical solution is explored. Similar results are also discussed in the case of entropy penalized density estimation.

description: Recently, the Monash Gender and Family Violence Prevention Centre undertook research to examine how and to what extent the Victorian State Government has engaged with faith-based leaders and communities from culturally and linguistically diverse (CALD) communities in Victoria. This research also explored the visions, challenges and needs for faith-based organisations in engaging in family violence education, training and other prevention activities. The research findings will inform future endeavours to address the prevention of family violence in faith settings considering the intersectional factors that are pivotal to ensure that such work meets the needs and interests of faith-based communities and their leaders. The research was undertaken with faith leaders and those who play key roles within faith-based organisations, representing four culturally and linguistically diverse backgrounds in Victoria.

description: This talk briefly explains how the breaking of a Lorentz-invariant description of nature at tiny space-time intervals might affect the non-Gaussian character of the primordial fluctuations left by inflation. For example, a model that contains irrelevant operators that only preserve the spatial symmetries along constant-time surfaces can generate a larger non-Gaussian component in the pattern of primordial fluctuations than is ordinarily predicted by inflation. This property can be useful for constraining models that allow some Lorentz violation at short distances, beyond the constraints possible from the power spectrum alone.

It has recently been used to accurately compute the zero-temperature phase diagram of the Bose-Hubbard model on a hypercubic lattice, up to arbitrary large filling and for d=2, 3 and greater [Teichmann et al., Phys.

description: So-called direct measurements of entanglement are collective measurements on multiple copies of a (bipartite or multipartite) quantum system that directly provide one a value for some entanglement measure, such as the concurrence for bipartite states. Multiple copies are needed since the entanglement of a mixed state is not a linear function of the density matrix. Unfortunately, so far all experimental implementations of direct measurements made unverified assumptions about the form of the states, and, therefore, do not qualify as entanglement verification tests. I discuss how a direct measurement can be turned into a quantitative entanglement verification test by exploiting a recent theorem by Renner (R. Renner, Nature Physics 3, 645 (2007)).

subject: rapid review
subject: scoping review

description: Background: Patient and family-centred care is a widely accepted standard in pediatric health care, particularly for children with chronic conditions. This protocol describes a planned rapid scoping review that aims to identify and characterise existing family-centred health care interventions that aim to improve experiences with health care for children with ongoing health care needs and their families. Methods: We will search Medline, Embase, PsycInfo, and Cochrane databases, and pertinent grey literature sources from 2010 to present for published articles or grey literature reports/policy documents describing family-centred care interventions that aim to improve experiences with health care for children with ongoing, elevated health care needs and/or their families. We will include primary studies with >10 participants, clinical practice guidelines, and theoretical articles. We will use a two-stage, two-reviewer screening process, and chart data on the population and intervention. Results will be synthesised and presented in narrative and table form. Discussion: This rapid scoping review is designed to be rigorous with methodological limits that adhere to time constraints anticipated for the conduct of the review. This study expects to identify existing family-centred care interventions that can be further examined, adopted, and/or adapted by future researchers and health care providers and administrators interested in improving health care for children with a broad range of care needs and their families.

description: The main goal of this note is to establish a connection between the cotype of the Banach space X and the parameters r for which every 2-homogeneous polynomial on X is r-dominated. Let cotX be the infimum of the cotypes assumed by X and (cotX)* be its conjugate. The main result of this note asserts that if cotX > 2, then for every 1<= r < (cotX)* there exists a non-r-dominated 2-homogeneous polynomial on X.

description: Measurements of Tritium have been performed, using a very low background and accurate instrumentation, on electrolytes before and after Deuterium absorption in Palladium wires. Tritium was always present in the electrolytic cells, having long and thin Palladium wires (carefully degassed) as cathode and Platinum wire as anode, because "normal contamination" of deuterated liquids. Two different kinds of electrolytes were used (unusual, for several aspects, to conventional ones adopted in Cold Fusion experiments): the first one was composed by heavy water in DCl acidic environment (pH=4.5) with the addition of Strontium (and Mercury) salts at micro-molar concentration, the second one was composed by heavy ethyl alcohol--heavy water solution (concentration ratio about 11:1), acidic environment (DCl+D2SO4), with the addition of Strontium and Mercury concentrated as before.We have found anomalous Tritium production (at large statistical significance) only when the achieved loading ratio (D/Pd) was quite large (about 0.95) and several loading/deloading cycles had been performed.

description: Under some plausible assumptions, we find that the dual formulation of linearized gravity in D=5 can be nontrivially coupled to the topological BF model in such a way that the interacting theory exhibits a deformed gauge algebra and some deformed, on-shell reducibility relations. Moreover, the tensor field with the mixed symmetry (2,1) gains some shift gauge transformations with parameters from the BF sector.

description: The maintenance of colour variation in wild populations has long fascinated evolutionary biologists, although most studies have focussed on discrete traits exhibiting rather simple inheritance patterns and genetic architectures. However, the study of continuous colour traits and their potentially oligo- or polygenic genetic bases remains rare in wild populations. We studied the genetics of the continuously varying white-to-rufous plumage coloration of the European barn owl (Tyto alba) using a Genome-Wide Association approach on the whole-genome data of 75 individuals. We confirmed a mutation at the melanocortin-1-receptor gene (MC1R) is involved in the coloration and identified two new regions, located in super-scaffolds 9 and 42. The combination of the three regions explains most of colour variation (80.37%, 95% credible interval 58.45–100%). One discovered region, located in the sex chromosome, differs between the most extreme colorations in owls sharing a specific MC1R genotype. This region may play a role in the colour sex dimorphism of this species, possibly in interaction with the autosomal MC1R. We thus provide insights into the genetic architecture of continuous colour variation, pointing to an oligogenic basis with potential epistatic effects among loci that should aid future studies understanding how continuous colour variation is maintained in nature.

description: A comparative analysis of sustainable development in the category of economic order at the regional level has been
 carried out. A comparison of the level of implementation of the guidelines for economic order in Polish provinces
 has been made. The following research questions were formulated: Q1: What are the methods to apply in order to
 assess the level of sustainable development in the light of the plethora of the strategic goals of sustainable
 development and the implementation indicators of these goals; Q2: Do Polish provinces implement the assumptions
 of the sustainable development strategy with comparable efficiency. The following hypotheses were formulated: H1:
 The objects under research show significant differences in terms of the taxonomic distances between the synthetic
 measure of development which confirms the validity of applying the multidimensional analysis for measuring the
 levels of sustainable development; H2: Polish provinces differ significantly in terms of the level of sustainable
 development in the category of economic order. The aim of this article is to objectively measure the progress in the
 implementation of the goals of the sustainable development strategy in the category of economic order by Polish
 provinces. In order to meet the formulated goal, a synthetic measure was built with a view to defining the
 implementation level of the goals formulated in the sustainable development strategy in the category of economic
 order.

description: We present dust opacity spectral indexes (beta) of the youngest protostellar systems (so-called Class 0 sources), L1448 IRS 2, L1448 IRS 3, and L1157, obtained between 1.3 mm and 2.7 mm continua, using the Combined Array for Research in Millimeter-wave Astronomy (CARMA). The unprecedented compact configuration and image fidelity of CARMA allow a better detection of the dust continuum emission from Class 0 sources, with a less serious missing flux problem normally associated with interferometry. Through visibility-modeling at both 1.3 mm and 2.7 mm simultaneously, as well as image- and visibility-comparison, we show that beta of the three Class 0 sources are around or smaller than 1, indicating that dust grains have already significantly grown at the Class 0 stage. In addition, we find a radial dependence of beta, which implies faster grain growth in the denser central regions and/or dust segregation. Density distributions of the Class 0 sources are also addressed by visibility-modeling.

description: A prototype Silicon-Tungsten electromagnetic calorimeter (ECAL) for an International Linear Collider (ILC) detector was installed and tested during summer and autumn 2006 at CERN. The detector had 6480 silicon pads of dimension 1x1 cm^2. Data were collected with electron beams in the energy range 6 to 45 GeV. The analysis described in this paper focuses on electromagnetic shower reconstruction and characterises the ECAL response to electrons in terms of energy resolution and linearity. The detector is linear to within approximately the 1% level and has a relative energy resolution of (16.6 +- 0.1)/ \sqrt{E(GeV}) + 1.1 +- 0.1 (%). The spatial uniformity and the time stability of the ECAL are also addressed.
