Scarcity and organizational theory
Creators: name: Moudgill, Pravin
Publisher: name: University of British Columbia
Year: 2010

description: There is reason to believe that the world is approaching its limits to growth. The level of natural resources is dwindling rapidly. This diminution is expected to have major consequences for all human activity. The possible effects of environmental scarcity on organizational behaviour were analyzed in this dissertation. The operational problem as defined was: to study at the macro level of analysis the organizational consequences of reduction of matter-energy inputs. It was pointed out that current organizational theory COT) is both consciously and unwittingly biased towards abundance and growth, and that there is little understanding of the imperatives of scarcity in O.T. Evidence to this effect was presented. The concept of scarcity was introduced and the centrality of survival as a determinant of behaviour was used to obtain a definition of scarcity. Two types of definitions were generated: (1) relative scarcity, i.e., scarcity as it relates to the focal organization, and (ii) absolute scarcity, i.e., scarcity in the context of the larger geopolitical system. These definitions were explicated with the help of some basic tools of microeconomic analysis. The definitions were relevant to both organizational as well as nonorganizational behaviour. The inter- and intra-organizational consequences of scarcity were studied separately. Interorganizational strategies which seek to reverse the antecedents of scarcity or to avoid experiencing its consequences were analyzed in detail. The various prescriptions were presented in the form of propositions, and contrasted to those characteristic of behaviour under abundance. A new definition of power was also developed. It was noted that scarcity may be expected to be (i) temporary, (ii) permanent, but not so severe as to cause failure in the long run, and (iii) gradually worsening scarcity such that the organisation expects to fail in the long run. Intraorganisational consequences of the three different modes of scarcity were discussed separately. The particular response strategies to be used under norms of rationality, i.e., to insure survival, were developed in the propositional form in each case. These strategies were compared and contrasted to those characteristic of abundance. Scarcity of availability of supplies is generally accompanied by uncertainty regarding their availability. Two "ideal types" of organisations were described; and it was suggested that, depending on the degree of scarcity, the two types are most likely to survive under conditions of permanent low level availability of matter-energy inputs.

description: We elucidated the reason why the average total kinetic energy (TKE) of fission fragments decreases when the excitation energy of the fissioning systems increases as indicated by experimental data for the neutron-induced fission events. To explore this problem, we used a method based on the four-dimensional Langevin equations we have developed. We have calculated the TKE of fission fragments for fissioning systems $^{236}$U$^{*}$ and $^{240}$Pu$^{*}$ excited above respective fission barriers, and compared the results with experimental data for n + $^{235}$U and n + $^{239}$Pu reactions, respectively. From the Langevin-model analysis, we have found that the shape of the abundant heavy fragments changes from almost spherical for low excitation domain to highly prolate shape for high excitation energy, while that of the light fragments does not change noticeably. The change of the "shape" of the heavy fragments causes an increase of a distance between the charge centers of the nascent fragments just after scission as excitation energy increases. Accordingly, the Coulomb repulsion between the two fragments decreases with an increase of the excitation energy, which causes the decrease of the average TKE. In this manner, we found that the change of the shape of the heavy fragment as a function of the excitation energy is the key issue for the TKE of fission fragments to decrease as the excitation energy of the fissioning nuclei increases. In other words, washing out of the shell effects which affect the shape of the heavy fragments is the key reason for the decreasing energy dependence of the average TKE of the fission fragments.

description: We introduce a generalized version of the Jang equation, designed for the general case of the Penrose Inequality in the setting of an asymptotically flat space-like hypersurface of a spacetime satisfying the dominat energy condition. The appropriate existence and regularity results are established in the special case of spherically symmetric Cauchy data, and are applied to give a new proof of the general Penrose Inequality for these data sets. When appropriately coupled with an inverse mean curvature flow, analogous existence and regularity results for the associated system of equations in the nonspherical setting would yield a proof of the full Penrose Conjecture. Thus it remains as an important and challenging open problem to determine whether this system does indeed admit the desired solutions.

description: On the basis of frequentist analyses of experimental constraints from electroweak precision data, g-2, B physics and cosmological data, we investigate the parameters of the constrained MSSM (CMSSM) with universal soft supersymmetry-breaking mass parameters, and a model with common non-universal Higgs masses (NUHM1). We present chi^2 likelihood functions for the masses of supersymmetric particles and Higgs bosons, as well as b to s gamma, b to mu mu and the spin-independent dark matter scattering cross section. In the CMSSM we find preferences for sparticle masses that are relatively light. In the NUHM1 the best-fit values for many sparticle masses are even slightly smaller, but with greater uncertainties. The likelihood functions for most sparticle masses are cut off sharply at small masses, in particular by the LEP Higgs mass constraint. Both in the CMSSM and the NUHM1, the coannihilation region is favoured over the focus-point region at about the 3-sigma level, largely but not exclusively because of g-2. Many sparticle masses are highly correlated in both the CMSSM and NUHM1, and most of the regions preferred at the 95% C.L. are accessible to early LHC running. Some slepton and chargino/neutralino masses should be in reach at the ILC. The masses of the heavier Higgs bosons should be accessible at the LHC and the ILC in portions of the preferred regions in the (M_A, tan beta) plane. In the CMSSM, the likelihood function for b to mu mu is peaked close to the Standard Model value, but much larger values are possible in the NUHM1. We find that values of the DM cross section > 10^{-10} pb are preferred in both the CMSSM and the NUHM1. We study the effects of dropping the g-2, b to s gamma, relic density and M_h constraints.

description: We propose several novel physical phenomena based on nano-scale helical wires. Applying a static electric field transverse to the helical wire induces a metal to insulator transition, with the band gap determined by the applied voltage. Similar idea can be applied to "geometrically" constructing one-dimensional systems with arbitrary external potential. With a quadrupolar electrode configuration, the electric field could rotate in the transverse plane, leading to a quantized dc charge current proportional to the frequency of the rotation. Such a device could be used as a new standard for the high precession measurement of the electric current. The inverse effect implies that passing an electric current through a helical wire in the presence of a transverse static electric field can lead to a mechanical rotation of the helix. This effect can be used to construct nano-scale electro-mechanical motors. Finally, our methodology also enables new ways of controlling and measuring the electronic properties of helical biological molecules such as the DNA.

Stability and change in electoral patterns : the case of the 1972 British Columbia provincial election in Vancouver
Creators: name: Rumley, Dennis
Publisher: name: University of British Columbia
Year: 2010

description: This dissertation demonstrates how variables previously neglected in voting studies - the political culture of the political system, migration, models of political space, area integration, and the geography of campaigning - can increase our understanding of the stability and change of electoral patterns. The variables are examined in three local areas in Vancouver, Canada, for the 1972 British Columbia Provincial Election. Data were obtained from personal interviews of inhabitants of the three local areas, and by personal interviews of representatives of the competing political parties. The argument is presented that B.C. political culture is essentially class-based and this provides a background understanding to the development of particular political norms in the three areas studied. The 1972 election is seen in the context of B.C. political history as an election of reaction against the Social Credit Party. Areas of consistent voting habits (political norms) are identified in Vancouver and a model of political space describing these consistencies is presented. Migration data are used to show that individuals tend to move to areas whose political norm is the same as their own political preference. A variety of latent and manifest measures of functional integration are used to show differences in the level of integration in the three areas under study. Status and voting behaviour are found to be associated. Associations between latent integration measures are found at the aggregate and individual levels. Individuals with a high degree of attachment to their area of residence are shown to vote in relation to the 'area norm'. Differences in the spatial organisation of political party campaigns and differences in the degree of spatial competition of canvassing are shown to be associated with differences in electoral outcome. Polls for which parties competed strongly tended to vote disproportionately in relation to the area norm, although this varied with the degree of integration of the area concerned.

description: Skyline is widely used in reality to solve multi-criteria problems, such as environmental monitoring and business decision-making. When a data is not worse than another data on all criteria and is better than another data at least one criterion, the data is said to dominate another data. When a data item is not dominated by any other data item, this data is said to be a member of the skyline. However, as the number of criteria increases, the possibility that a data dominates another data decreases, resulting in too many members of the skyline set. To solve this kind of problem, the concept of the k-dominant skyline was proposed, which reduces the number of skyline members by relaxing the limit. The uncertainty of the data makes each data have a probability of appearing, so each data has the probability of becoming a member of the k-dominant skyline. When a new data item is added, the probability of other data becoming members of the k-dominant skyline may change. How to quickly update the k-dominant skyline for real-time applications is a serious problem. This paper proposes an effective method, Middle Indexing (MI), which filters out a large amount of irrelevant data in the uncertain data stream by sorting data specifically, so as to improve the efficiency of updating the k-dominant skyline. Experiments show that the proposed MI outperforms the existing method by approximately 13% in terms of computation time.

description: PurposeThe purpose of this paper is to present empirical evidence on the implementation, acceptance and quality-related aspects of research information systems (RIS) in academic institutions.Design/methodology/approachThe study is based on a 2018 survey with 160 German universities and research institutions.FindingsThe paper presents recent figures about the implementation of RIS in German academic institutions, including results on the satisfaction, perceived usefulness and ease of use. It contains also information about the perceived data quality and the preferred quality management. RIS acceptance can be achieved only if the highest possible quality of the data is to be ensured. For this reason, the impact of data quality on the technology acceptance model (TAM) is examined, and the relation between the level of data quality and user acceptance of the associated institutional RIS is addressed.Research limitations/implicationsThe data provide empirical elements for a better understanding of the role of the data quality for the acceptance of RIS, in the framework of a TAM. The study puts the focus on commercial and open-source solutions while in-house developments have been excluded. Also, mainly because of the small sample size, the data analysis was limited to descriptive statistics.Practical implicationsThe results are helpful for the management of RIS projects, to increase acceptance and satisfaction with the system, and for the further development of RIS functionalities.Originality/valueThe number of empirical studies on the implementation and acceptance of RIS is low, and very few address in this context the question of data quality. The study tries to fill the gap.

USE OF A CELL PERMEABLE PEPTIDE TO MODULATE ADAM10 SYNAPTIC LOCALIZATION AND ACTIVITY IN A MOUSE MODEL OF ALZHEIMER'S DISEASE
Creators: name: THERIN, SEBASTIEN
Publisher: name: Universit� degli Studi di Milano

description: Alzheimer?s disease (AD) is characterized by the aggregation of amyloid beta peptide (A?). A? derives from the amyloid precursor protein (APP), which can undergo two mutually exclusive pathways. The amyloidogenic pathway involves BACE and ?-secretase activities and leads to A? formation. While, the non-amyloidogenic pathway involves ADAM10, a disintegrin and metalloproteinase 10, which cleaves APP within the domain corresponding to A?, thus precluding A? production. Recently, we identified a new ADAM10 binding partner, named AP2, which is responsible for ADAM10 internalization, therefore affecting its activity. Interestingly, ADAM10/AP2 interaction is significantly increased in AD patients' brain compared to healthy control subjects, suggesting a role of ADAM10/AP2 in AD pathogenesis. In this framework, we have recently developed a cell permeable peptide (named PEP3) capable of interfering with ADAM10/AP2 association. The intraperitoneal administration of this CPP to a mouse model of AD for two weeks is safe and effective in impairing ADAM10 endocytosis and, thereby, in increasing ADAM10 synaptic localization. At late stages of disease, the PEP3 administration is able to change biochemical parameters, as A? levels and the molecular composition of the synapses without ameliorating the cognitive deficits of these mice. On the other hand, at early stage of the pathology the 14-days administration of the PEP3 rescues the cognitive impairment of the AD mice. Further investigations revealed that the synaptic levels of the NMDA receptor subunit GluN2A are increased upon the treatment and that previously observed shrinkage and dendritic spine loss in AD mice were improved after CPP treatment. These results are mediated by an increase in endogenous sAPP?. These positive results point to ADAM10 internalization as a potential target mechanism for the development of an effective AD therapy.

description: Data sets derived from practical experiments often pose challenges for (robust) statistical methods. In high-dimensional data sets, more variables than observations are recorded and often, there are also data present that do not follow the structure of the data majority. In order to handle such data with outlying observations, a variety of robust regression and classification methods have been developed for low-dimensional data. The high-dimensional case, however, is more challenging, and the variety of robust methods is much more limited. The choice of the method depends on the specific data structure, and numerical problems are more likely to occur. We give an overview of selected robust methods as well as implementations and demonstrate the application with two high-dimensional data sets from tribology. We show that robust statistical methods combined with appropriate pre-processing and sampling strategies yield increased prediction performance and insight into data differing from the majority.

TOWARDS A COMPUTATIONAL MODEL OF RETINAL STRUCTURE AND BEHAVIOR
Creators: name: LANARO, MATTEO PAOLO
Publisher: name: Universit� degli Studi di Milano
Year: 2020

description: Human vision is our most important sensory system, allowing us to perceive our surroundings. It is an extremely complex process that starts with light entering the eye and ends inside of the brain, with most of its mechanisms still to be explained. When we observe a scene, the optics of the eye focus an image on the retina, where light signals are processed and sent all the way to the visual cortex of the brain, enabling our visual sensation. The progress of retinal research, especially on the topography of photoreceptors, is often tied to the progress of retinal imaging systems. The latest adaptive optics techniques have been essential for the study of the photoreceptors and their spatial characteristics, leading to discoveries that challenge the existing theories on color sensation. The organization of the retina is associated with various perceptive phenomena, some of them are straightforward and strictly related to visual performance like visual acuity or contrast sensitivity, but some of them are more difficult to analyze and test and can be related to the submosaics of the three classes of cone photoreceptors, like how the huge interpersonal differences between the ratio of different cone classes result in negligible differences in color sensation, suggesting the presence of compensation mechanisms in some stage of the visual system. In this dissertation will be discussed and addressed issues regarding the spatial organization of the photoreceptors in the human retina. A computational model has been developed, organized into a modular pipeline of extensible methods each simulating a different stage of visual processing. It does so by creating a model of spatial distribution of cones inside of a retina, then applying descriptive statistics for each photoreceptor to contribute to the creation of a graphical representation, based on a behavioral model that determines the absorption of photoreceptors. These apparent color stimuli are reconstructed in a representation of the observed scene. The model allows the testing of different parameters regulating the photoreceptor's topography, in order to formulate hypothesis on the perceptual differences arising from variations in spatial organization.

description: After the discovery of graphene, there have been tremendous efforts in exploring various layered two-dimensional (2D) materials for their potential applications in electronics, optoelectronics, as well as energy conversion and storage. One of such 2D materials, SnS2, which is earth abundant, low in toxicity, and cost effective, has been reported to show a high on/off current ratio, fast photodetection, and high optical absorption, thus making this material promising for device applications. Further, a few recent theoretical reports predict high electrical conductivity and Seebeck coefficient in its bulk counterparts. However, the thermal properties of SnS2 have not yet been properly explored, which are important to materialize many of its potential applications. Here, we report the thermal properties of SnS2 measured using the optothermal method and supported by density functional theory (DFT) calculations. Our experiments suggest very low in-plane lattice thermal conductivity (\k{appa} = 3.20 +- 0.57 W m-1 K-1) and cross-plane interfacial thermal conductance per unit area (g = 0.53 +- 0.09 MW m-2 K-1) for monolayer SnS2 supported on a SiO2/Si substrate. The thermal properties show a dependence on the thickness of the SnS2 flake. Based on the findings of our DFT calculations, the very low value of the lattice thermal conductivity can be attributed to low group velocity, a shorter lifetime of the phonons, and strong anharmonicity in the crystal. Materials with low thermal conductivity are important for thermoelectric applications as the thermoelectric power coefficient goes inversely with the thermal conductivity.
Occurrence. fate. and related health risks of PFAS in raw and produced drinking water

description: This study investigates human exposure to per- and polyfluoroalkyl substances (PFAS) via drinking water and evaluates human health risks. An analytical method for 56 target PFAS, including ultrashort-chain (C2–C3) and branched isomers, was developed. The limit of detection (LOD) ranged from 0.009 to 0.1 ng/L, except for trifluoroacetic-acid and perfluoropropanoic-acid with higher LODs of 35 and 0.24 ng/L, respectively. The method was applied to raw and produced drinking water from 18 Dutch locations, including groundwater or surface water as source, and applied various treatment processes. Ultrashort-chain (300 to 1100 ng/L) followed by the group of perfluoroalkyl-carboxylic-acids (PFCA, ≥C4) (0.4 to 95.1 ng/L) were dominant. PFCA and perfluoroalkyl-sulfonic-acid (≥C4), including precursors, showed significantly higher levels in drinking water produced from surface water. However, no significant difference was found for ultrashort PFAS, indicating the need for groundwater protection. Negative removal of PFAS occasionally observed for advanced treatment indicates desorption and/or degradation of precursors. The proportion of branched isomers was higher in raw and produced drinking water as compared to industrial production. Drinking water produced from surface water, except for a few locations, exceed non-binding provisional guideline values proposed; however, all produced drinking waters met the recent soon-to-be binding drinking-water-directive requirements.

description: Scene text recognition (STR) is an important bridge between images and text, attracting abundant research attention. While convolutional neural networks (CNNS) have achieved remarkable progress in this task, most of the existing works need an extra module (context modeling module) to help CNN to capture global dependencies to solve the inductive bias and strengthen the relationship between text features. Recently, the transformer has been proposed as a promising network for global context modeling by self-attention mechanism, but one of the main shortcomings, when applied to recognition, is the efficiency. We propose a 1-D split to address the challenges of complexity and replace the CNN with the transformer encoder to reduce the need for a context modeling module. Furthermore, recent methods use a frozen initial embedding to guide the decoder to decode the features to text, leading to a loss of accuracy. We propose to use a learnable initial embedding learned from the transformer encoder to make it adaptive to different input images. Above all, we introduce a novel architecture for text recognition, named TRansformer-based text recognizer with Initial embedding Guidance (TRIG), composed of three stages (transformation, feature extraction, and prediction). Extensive experiments show that our approach can achieve state-of-the-art on text recognition benchmarks.

description: The recently observed X(3872) resonance, which is difficult to be assigned a conventional $c\bar{c}$ charmonium state in the quark model, may be interpreted as a molecular state. Such a molecular state is a hidden flavor four quark state because of its charmonium-like quantum numbers. The s-channel one gluon exchange is an interaction which only acts in the hidden flavor multi-quark system. In this paper, we will study the X(3872) and other similiar hidden flavor molecular states in a quark model by taking into account of the s-channel one gluon exchange interaction.
HOOKING TRAIL-R2 TO �EDUCATE� IMMUNE SYSTEM TO RECOGNIZE CANCER CELLS

description: Use of recombinant human tumor necrosis factor (TNF) related apoptosis inducing ligand (rhTRAIL) or TRAIL-receptors agonistic monoclonal antibodies (mAbs) promotes apoptosis in most cancer cells preserving normal cells. Furthermore, TRAIL-R2, one of the receptor that can trigger cell apoptotic machinery, is expressed at higher levels in tumor tissue as compared to normal tissues. Agonistic mAbs could mimic the tumor killing properties of rhTRAIL, with the advantage to have a prolonged half-life in vivo and to avoid binding of decoy TRAIL-receptors unable to transmit apoptotic signals. Although mAbs have proven to be highly effective, their use still unsolved the problem of TRAIL-resistance that some tumor cells are able to develop. To increase the anti-tumor activity of some mAbs, in last decades, bispecific antibodies (BsAbs) able to redirect cytotoxic activity of tumor resident/ circulating T cells against tumor cells in an MHC-independent fashion have been developed. In this study, we isolated a BsAb able to bind the CD3, invariant component of the T-cell receptor, and TRAIL-R2. Among the different isolated BsAbs, one in particular presented good thermodynamic characteristics and showed a very good stability even after 2 years its purification. The BsAb was biochemically and functionally well characterized and the production method was optimized. We demonstrated that the BsAb could act with two mechanisms: retargeting T-cells to lyse tumor cells when acting as BsAb and activating apoptotic pathway by triggering TRAIL-R2 when acting as agonistic mAb. T-cell activation was confirmed by up-regulation of CD69 and CD25 and by production of inflammatory cytokines without off target toxicity. In vitro we demonstrated that, after BsAb-mediated retargeting, T cells were able to lyse tumors of different histotypes, like melanoma, breast and ovarian cancer while sparing normal cells.

description: The census of the globular clusters (GCs) in the Milky Way (MW) is still a work in progress. We explore the nature of 19 new GC candidates in the Galactic bulge, based on the analysis of their colour-magnitude diagrams (CMDs) in the near-IR, using the VISTA Variables in the Via Láctea Survey (VVV) database. We estimate their main astrophysical parameters: reddening and extinction, distance, total luminosity, mean cluster proper motions (PMs), metallicity and age. We obtain the cluster catalogues including the likely cluster members by applying a decontamination procedure on the observed CMDs, based upon the vector PM diagrams from VIRAC2. We estimate a wide reddening range of the $0.25 \leqslant E(J-K_s) \leqslant 2.0$ mag and extinction $0.11 \leqslant A_{Ks} \leqslant 0.86$ mag for the sample clusters as expected in the bulge regions. The range of heliocentric distances is $6.8\leqslant D\leqslant 11.4$ kpc. This allows us to place these clusters between 0.56 and 3.25 kpc from the Galactic centre, assuming $R_{\odot}=8.2$ kpc. Also, their PMs are kinematically similar to the typical motion of the Galactic bulge, apart from VVV-CL160, which shows different PMs. We also derive their metallicities and ages, finding $-1.40 \leqslant$ [Fe/H] $\leqslant 0.0$ dex and $t\approx 8-13$ Gyr respectively. The luminosities are calculated both in $K_{s}-$ and V-bands, recovering $-3.4 \leqslant M_V \leqslant -7.5$. We also examine the possible RR Lyrae members found in the cluster fields. Based on their positions, kinematics, metallicities and ages and comparing our results with the literature, we conclude that 9 candidates are real GCs, 7 need more observations to be fully confirmed as GCs, whereas 3 candidates are discarded for being younger open clusters.

description: The proton-proton and proton-eta' invariant mass distributions have been determined for the pp -> ppeta' reaction at an excess energy of Q = 16.4 MeV. The measurement was carried out using the COSY-11 detector setup and the proton beam of the cooler synchrotron COSY. The shapes of the determined invariant mass distributions are similar to those of the pp -> ppeta reaction and reveal an enhancement for large relative proton-proton momenta. This result, together with the fact that the proton-eta interaction is much stronger that the proton-eta' interaction, excludes the hypothesis that the observed enhancement is caused by the interaction between the proton and the meson.

description: In this paper we investigate "Warm Electron Injection" as a mechanism for NOR programming of double-gate SONOS memories through 2D full band Monte Carlo simulations. Warm electron injection is characterized by an applied VDS smaller than 3.15 V, so that electrons cannot easily accumulate a kinetic energy larger than the height of the Si/SiO2 barrier. We perform a time-dependent simulation of the program operation where the local gate current density is computed with a continuum-based method and is adiabatically separated from the 2D full Monte Carlo simulation used for obtaining the electron distribution in the phase space. In this way we are able to compute the time evolution of the charge stored in the nitride and of the threshold voltages corresponding to forward and reverse bias. We show that warm electron injection is a viable option for NOR programming in order to reduce power supply, preserve reliability and CMOS logic level compatibility. In addition, it provides a well localized charge, offering interesting perspectives for multi-level and dual bit operation, even in devices with negligible short channel effects.

description: The present article proposes an extension of the concept of adverse childhood experiences (ACEs) to apply to crisis migration – where youth and families are fleeing armed conflicts, natural disasters, community violence, government repression, and other large-scale emergencies. We propose that adverse events occurring prior to, during, and following migration can be classified as crisis-migration-related ACEs, and that the developmental logic underlying ACEs can be extended to the new class of crisis-migration-related ACEs. Specifically, greater numbers, severity, and chronicity of crisis-migration-related ACEs would be expected to predict greater impairments in mental and physical health, poorer interpersonal relationships, and less job stability later on. We propose a research agenda centered around definitional clarity, rigorous measurement development, prospective longitudinal studies to establish predictive validity, and collaborations among researchers, practitioners, and policymakers.

description: Resonant laser scattering along with photon correlation measurements have established the atom-like character of quantum dots. Here, we present measurements which challenge this identification for a wide range of experimental parameters: the absorption lineshapes that we measure at magnetic fields exceeding 1 Tesla indicate that the nuclear spins polarize by an amount that ensures locking of the quantum dot resonances to the incident laser frequency. In contrast to earlier experiments, this nuclear spin polarization is bi-directional, allowing the electron+nuclear spin system to track the changes in laser frequency dynamically on both sides of the quantum dot resonance. Our measurements reveal that the confluence of the laser excitation and nuclear spin polarization suppresses the fluctuations in the resonant absorption signal. A master equation analysis shows narrowing of the nuclear Overhauser field variance, pointing to potential applications in quantum information processing.

description: Education artificial intelligence aims to profit tasks in the education domain such as intelligent test paper generation and consolidation exercises where the main technique behind is how to match the exercises, known as the finding similar exercises(FSE) problem. Most of these approaches emphasized their model abilities to represent the exercise, unfortunately there are still many challenges such as the scarcity of data, insufficient understanding of exercises and high label noises. We release a Chinese education pre-trained language model BERT$_{Edu}$ for the label-scarce dataset and introduce the exercise normalization to overcome the diversity of mathematical formulas and terms in exercise. We discover new auxiliary tasks in an innovative way depends on problem-solving ideas and propose a very effective MoE enhanced multi-task model for FSE task to attain better understanding of exercises. In addition, confidence learning was utilized to prune train-set and overcome high noises in labeling data. Experiments show that these methods proposed in this paper are very effective.

description: SDN and NFV have recently changed the way we operate networks. By decoupling control and data plane operations and virtualising their components, they have opened up new frontiers towards reducing network ownership costs and improving usability and efficiency. Recently, their applicability has moved towards public telecommunications networks, with concepts such as the cloud-CO that have pioneered its use in access and metro networks: an idea that has quickly attracted the interest of network operators. By merging mobile, residential and enterprise services into a common framework, built around commoditised data centre types of architectures, future embodiments of this CO virtualisation concept could achieve significant capital and operational cost savings, while providing customised network experience to high-capacity and low-latency future applications. This tutorial provides an overview of the various frameworks and architectures outlining current network disaggregation trends that are leading to the virtualisation/cloudification of central offices. It also provides insight on the virtualisation of the access-metro network, showcasing new software functionalities like the virtual \ac{DBA} mechanisms for \acp{PON}. In addition, we explore how it can bring together different network technologies to enable convergence of mobile and optical access networks and pave the way for the integration of disaggregated ROADM networks. Finally, this paper discusses some of the open challenges towards the realisation of networks capable of delivering guaranteed performance, while sharing resources across multiple operators and services.
