description: Amid the pandemic of 2019 novel coronavirus disease (COVID-19) infected by SARS-CoV-2, a vast amount of drug research for prevention and treatment has been quickly conducted, but these efforts have been unsuccessful thus far. Our objective is to prioritize repurposable drugs using a drug repurposing pipeline that systematically integrates multiple SARS-CoV-2 and drug interactions, deep graph neural networks, and in-vitro/population-based validations. We first collected all the available drugs (n= 3,635) involved in COVID-19 patient treatment through CTDbase. We built a SARS-CoV-2 knowledge graph based on the interactions among virus baits, host genes, pathways, drugs, and phenotypes. A deep graph neural network approach was used to derive the candidate representation based on the biological interactions. We prioritized the candidate drugs using clinical trial history, and then validated them with their genetic profiles, in vitro experimental efficacy, and electronic health records. We highlight the top 22 drugs including Azithromycin, Atorvastatin, Aspirin, Acetaminophen, and Albuterol. We further pinpointed drug combinations that may synergistically target COVID-19. In summary, we demonstrated that the integration of extensive interactions, deep neural networks, and rigorous validation can facilitate the rapid identification of candidate drugs for COVID-19 treatment.

description: Initially developed for natural language processing (NLP), Transformers are now widely used for source code processing, due to the format similarity between source code and text. In contrast to natural language, source code is strictly structured, i.e., it follows the syntax of the programming language. Several recent works develop Transformer modifications for capturing syntactic information in source code. The drawback of these works is that they do not compare to each other and consider different tasks. In this work, we conduct a thorough empirical study of the capabilities of Transformers to utilize syntactic information in different tasks. We consider three tasks (code completion, function naming and bug fixing) and re-implement different syntax-capturing modifications in a unified framework. We show that Transformers are able to make meaningful predictions based purely on syntactic information and underline the best practices of taking the syntactic information into account for improving the performance of the model.

Year: 1986
Subjects: Community/Rural/Urban Development

description: This paper focuses on state economic development efforts with an emphasis on formulating a state economic development strategy. An analytical framework for regional policy analysis is discussed. A second framework is presented that outlines criteria for efficient use of state funds. Economic Base theory is discussed in the appendix, along with Shift-Share Analysis. States, although generally lacking a comprehensive development strategy, are active in economic development programs. The "bottom line" in all regional development efforts is enhancement of the productivity of regional resources, particularly human. To ensure the productive use of state financing, eligible candidates for state assistance are being targeted for export-producing businesses that could not achieve their potential for success without this assistance. These programs should be subject to the criterion that the benefits of programs, measured in increased taxes due to the development, be greater than the total cost of the programs and incentives.

description: 3D hand pose estimation from monocular videos is a long-standing and challenging problem, which is now seeing a strong upturn. In this work, we address it for the first time using a single event camera, i.e., an asynchronous vision sensor reacting on brightness changes. Our EventHands approach has characteristics previously not demonstrated with a single RGB or depth camera such as high temporal resolution at low data throughputs and real-time performance at 1000 Hz. Due to the different data modality of event cameras compared to classical cameras, existing methods cannot be directly applied to and re-trained for event streams. We thus design a new neural approach which accepts a new event stream representation suitable for learning, which is trained on newly-generated synthetic event streams and can generalise to real data. Experiments show that EventHands outperforms recent monocular methods using a colour (or depth) camera in terms of accuracy and its ability to capture hand motions of unprecedented speed. Our method, the event stream simulator and the dataset are publicly available; see https://4dqv.mpi-inf.mpg.de/EventHands/

The recollapse problem of closed FRW models in higher-order gravity theories

description: We study the closed universe recollapse conjecture for positively curved FRW models with a perfect fluid matter source and a scalar field which arises in the conformal frame of the $R+αR^{2}$ theory. By including ordinary matter, we extend the analysis of a previous work. We analyze the structure of the resulted four-dimensional dynamical system with the methods of the center manifold theory and the normal form theory. It is shown that an initially expanding closed FRW universe, starting close to the Minkowski spacetime, cannot avoid recollapse. We discuss the posibility that potentials with a positive minimum may prevent the recollapse of closed universes.

description: Recently symmetries of gravity and gauge fields in the asymptotic regions of spacetime have been shown to play vital role in their low energy scattering phenomena. Further, for the black hole spacetime, near horizon symmetry has been observed to play possible role in understanding the underlying degrees of freedom for thermodynamic behaviour of horizon. Following the similar idea, in this paper, we analyzed the symmetry and associated algebra near a timelike surface which is situated at any arbitrary radial position and is embedded in black hole spacetime. In this paper we considered both Schwarzschild and Kerr black hole spacetimes. The families of hypersurfaces with constant radial coordinate (outside the horizon) in these spacetimes is timelike in nature and divide the space into two distinct regions. The symmetry algebra turned out to be reminiscent of Bondi-Metzner-Sach (BMS) symmetry, found in the asymptotic null infinity.

Simulation of Quantum Adiabatic Search in the Presence of Noise

Subjects: subject: Quantum Physics (quant-ph)

description: Results are presented of a large-scale simulation of the quantum adiabatic search (QuAdS) algorithm in the presence of noise. The algorithm is applied to the NP-Complete problem Exact Cover 3 (EC3). The noise is assumed to Zeeman-couple to the qubits and its effects on the algorithm's performance is studied for various levels of noise power, and for 4 different types of noise polarization. We examine the scaling relation between the number of bits N (EC3 problem size) and the algorithm's noise-averaged median run-time . Clear evidence is found of the algorithm's sensitivity to noise. Two fits to the simulation results were done: (1) power-law scaling = aN**b; and (2) exponential scaling = a[exp(bN) - 1]. Both types of scaling relations provided excellent fits. We demonstrate how noise leads to decoherence in QuAdS, estimate the amount of decoherence in our simulations, and derive an upper bound for the noise-averaged QuAdS success probability in the weak noise limit appropriate for our simulations.

description: Perturbation theory is an indispensable tool for studying the cosmic large-scale structure, and establishing its limits is therefore of utmost importance. One crucial limitation of perturbation theory is shell-crossing, which is the instance when cold-dark-matter trajectories intersect for the first time. We investigate Lagrangian perturbation theory (LPT) at very high orders in the vicinity of the first shell-crossing for random initial data in a realistic three-dimensional Universe. For this we have numerically implemented the all-order recursion relations for the matter trajectories, from which the convergence of the LPT series at shell-crossing is established. Convergence studies performed up to the 40th order reveal the nature of the convergence-limiting singularities. These singularities are not the well-known density singularities at shell-crossing but occur at later times when LPT already ceased to provide physically meaningful results.

Fossil records of cosmic reionization in galactic stellar halos

Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Galactic stellar halos have long been considered to contain fossil information on early dynamical and chemical evolution of galaxies. We propose that the surface brightness distributions of old stellar halos contain the influence of reionization on early formation histories of galaxies. By assuming that reionization significantly suppresses star formation in small subgalactic clumps virialized after reionization redshift ($z_{\rm reion}$), we first numerically investigate how structural and kinematical properties of stellar halos formed from merging of these subgalactic clumps depend on $z_{\rm reion}$. We then discuss what observable properties of galactic stellar halos offer us the fossil records of reionization influence on hierarchical formation of halos based on the current results of numerical simulations. We particularly suggest that both the half-light radius of stellar halos and the slope of their surface brightness profile contain useful information on when star formation in subgalactic clumps were significantly influenced by reionization. By using the simulated surface brightness distributions of galactic stellar halos for models with different $z_{\rm reion}$, we also discuss how wide-field imaging studies of extragalactic halos will help us to elucidate the epoch of cosmic reionization.

description: We evaluate the transition from zero-sound to first-sound behaviour with increasing collisionality in the propagation of density waves through an ultracold gaseous mixture of fermionic atoms confined in the normal state inside a cigar-shaped harmonic trap. We study for this purpose the evolution of the one-body distribution functions associated with a density perturbation generated in the central region of the cloud, as obtained by solving numerically the Vlasov-Landau equations. We examine a variety of trap anisotropies and of repulsive or attractive interaction strengths between the components of the mixture, and the speed of propagation of the density disturbance is found to decrease in both cases as the magnitude of the coupling strength is increased. The results are compared with the values of the speed of zero sound and of first sound, as obtained analytically from the limit of vanishing collisionality and from linearized hydrodynamics. The main effects of the quasi-one-dimensional confinement are the stabilization of zero-sound excitations in the attractive regime before collapse and the lowering of the hydrodynamic sound velocity by a factor \sqrt{3/5} relative to three-dimensional behaviour.

Perceptions of electoral fairness : public behaviour and institutional design compared across 80 countries

Year: 2014
Subjects: subject: Elections Management
subject: Public opinion
subject: Fairness

description: This thesis conducts a cross-national analysis of perceived electoral fairness across 80 countries in Africa, Asia, Europe, and the Americas. The main research question is focused on uncovering the determinants of perceived electoral fairness. The thesis focuses on two broad groups of variables and the structures of the chapters follow from this distinction. The first set of variables arises from a meta-analysis of previous studies to ascertain the strongest determinants of electoral fairness. This entails testing as many individual and national level variables as possible across as many countries as possible to reveal any global trends or regional differences. The second set of variables are all at the national level and arise from two theoretical models of electoral management body (EMB) design, both of which focus on evaluating the merits of EMB independence or autonomy from the ruling government. Once again, the approach is to examine as many aspects of electoral management design as possible across as many regions as possible. Results unexpectedly indicate frequent negative associations between EMB independence and perceived electoral fairness. The thesis considers different possibilities for these unexpected negative results probably caused by the many authoritarian democracies present in the regional datasets. The thesis uses multivariate ordered probit and multilevel mixed-effects regression models to conduct analyses at the national, regional, and global levels. Public survey data comes from the AfroBarometer, ArabBarometer, AmericasBarometer, AsianBarometer, and Comparative Study of Electoral Systems. National level indicators come from the Quality of Government, Administration and Cost of Elections (ACE) Electoral Knowledge Network and International Institute for Democracy and Electoral Assistance (IDEA).

Global energy (where applicable), quasi-local energy together with fluxes of these quantities are presented for both types of black holes, considering asymptotic spacetime as background. The same quantities are constructed for dynamic black holes on the background of the related static black holes. Besides, for the dynamic black holes, energy densities and densities of energy flux are calculated in the frame of freely and radially falling observer on the background of the related static black holes. All the constructed energetic characteristics are analyzed and discussed in detail.

description: We introduce the adiabatic quantum Monte Carlo (AQMC) method, where we gradually crank up the interaction strength, as an amelioration of the sign problem. It is motivated by the adiabatic theorem and will approach the true ground-state if the evolution time is long enough. We demonstrate that the AQMC enhances the average sign exponentially such that low enough temperatures can be accessed and ground-state properties probed. It is a controlled approximation that satisfies the variational theorem and provides an upper bound for the ground-state energy. We first benchmark the AQMC vis-à-vis the undoped Hubbard model on the square lattice which is known to be sign-problem-free within the conventional quantum Monte Carlo formalism. Next, we test the AQMC against the density-matrix-renormalization-group approach for the doped four-leg ladder Hubbard model and demonstrate its remarkable accuracy. As a nontrivial example, we apply our method to the Hubbard model at $p=1/8$ doping for a $16\times 8$ system and discuss its ground-state properties. We finally utilize our method and demonstrate the emergence of $U(1)_2\sim SU(2)_1$ topological order in a strongly correlated Chern insulator.

description: We consider a model with global Abelian chiral symmetry of two massless fermion fields interacting with a complex massive scalar field. We argue that the Schwinger-Dyson equations for the fermion and boson propagators admit ultraviolet-finite chiral-symmetry-breaking solutions provided the Yukawa couplings are large enough. The fermions acquire masses and the elementary excitations of the complex scalar field are the two real spin-zero particles with different masses. As a necessary consequence of the dynamical chiral symmetry breakdown both in the fermion and scalar sectors, one massless pseudoscalar Nambu--Goldstone boson appears in the spectrum as a collective excitation of both the fermion and the boson fields. Its effective couplings to the fermion and boson fields are calculable.

description: China is the most important pear producing country in the world, and one of the most important as far as it concerns apples. Nevertheless, its international role is not so relevant: traded volume in relation to production is relatively small yet growing fast. Xinjiang is a large and mainly deserted region in northwest China that covers one-sixth of China's land. However, thanks to abundant water resources, good lighting conditions and altitude, this area represents an ideal setting for pomefruit production, and has in fact a very long tradition. Unfortunately, due to a disadvantaged location and a poor economy this province do not attract enough capitals, passing unnoticed despite of its valuable resources. Economic analysis are therefore necessary to assess to which extent this market turns out to be approachable. The aim of this paper is to describe in detail the situation of the fruit growing industry in Xinjiang, as far as it concerns two important pomefruit varieties: Xiang Li pear, a local and very appreciated variety, and Fuji apple. After locating the most vocated producing areas for both species and identifying the productive standards, we then proceed on counting up the production costs, using a well-established methodology adapted to the particular situation. The target of the analysis are small and mid-size farms, since they represent the vast majority of the orchards of the area. The costs aggregates are: base orchard management cost (BOMC), farm full cost (FFC) and total production cost (TPC). These aggregates group together costs related to similar productive factors. The picture of the situation outlined by this survey is that of a marginal area, where however fruit growing, compared to other agricultural activities, grants a good income. It also emerges that fruit growers in Xinjiang (and in China), are hardly coming out of a situation of general backwardness, striving to adapt to a larger business mainly through exportation to other provinces. Farms are however mainly familiar and small, and only a few big local enterprises seem to possess the right requirements to give local production the right impetus to reach successfully outside markets.

description: Axion miniclusters are dense bound structures of dark matter axions that are predicted to form in the post-inflationary Peccei-Quinn symmetry breaking scenario. Although dense, miniclusters can easily be perturbed or even become unbound by interactions with baryonic objects such as stars. Here, we characterize the spatial distribution and properties of miniclusters in the Milky Way (MW) today after undergoing these stellar interactions throughout their lifetime. We do this by performing a suite of Monte Carlo simulations which track the miniclusters' structure and, in particular, accounts for partial disruption and mass loss through successive interactions. We consider two density profiles - Navarro-Frenk-White (NFW) and Power-law (PL) - for the individual miniclusters in order to bracket the uncertainties on the minicluster population today due to their uncertain formation history. For our fiducial analysis at the Solar position, we find a survival probability of 99% for miniclusters with PL profiles and 46% for those with NFW profiles. Our work extends previous estimates of this local survival probability to the entire MW. We find that towards the Galactic center, the survival probabilities drop drastically. Although we present results for a particular initial halo mass function, our simulations can be easily recast to different models using the provided data and code. Finally, we comment on the impact of our results on lensing, direct, and indirect detection.

description: Today's software development is increasingly performed with the help of low- and no-code platforms that follow model-driven principles and use domain-specific languages (DSLs). DSLs support the different aspects of the development and the user's mindset by a tailored and intuitive language. By combining specific languages with real-time collaboration, development environments can be provided whose users no longer need to be programmers. This way, domain experts can develop their solution independently without the need for a programmer's translation and the associated semantic gap. However, the development and distribution of collaborative mindset-supporting IDEs (mIDEs) is enormously costly. Besides the basic challenge of language development, a specialized IDE has to be provided, which should work equally well on all common platforms and individual heterogeneous system setups. This dissertation describes the conception and realization of the web-based, unified environment CINCO Cloud, in which DSLs can be collaboratively developed, used, transformed and executed. By providing full support at all steps, the philosophy of language-driven engineering is enabled and realized for the first time. As a foundation for the unified environment, the infrastructure of cloud development IDEs is analyzed and extended so that new languages can be distributed on-the-fly. Subsequently, concepts for language specialization, refinement and concretization are developed and described to realize the language-driven engineering approach, in a dynamic cluster-based environments. In addition, synchronization mechanisms and authorization structures are designed to enable collaboration between the users of the environment. Finally, the central aligned processes within the CINCO Cloud for developing, using, transforming and executing a DSL are illustrated to clarify how the dynamic system behaves.

description: 随着高品位钾盐资源日益稀缺，锂被认为是有价值的副产品，柴达木盆地马海盐湖的低品位固体钾矿床已成为钾盐资源开发的重要目标。然而，这些低品位矿石中钾的低效释放限制了它们工业使用的经济可行性。本研究通过采用 X 射线衍射 （XRD）、扫描电子显微镜耦合能量色散光谱 （SEM-EDS） 和观测钻孔监测数据来系统分析这些矿石的矿物学特征及其对固液转化过程中钾离子释放的影响，从而解决了这一挑战。结果确定光卤石、钾盐和杂卤石是主要的钾盐矿物，整个研究区域具有显着的空间变化，直接影响钾离子的释放和迁移。 浅层中的钾盐和光卤石与溶剂的反应性更强，有利于钾离子的快速释放，而多卤石位于岩盐的晶间碎屑材料中，表现出有限的孔隙连通性，导致释放速率较慢。 监测钻孔数据表明，溶剂注入量的变化会导致水位和钾离子浓度的显著波动，从而影响钾肥的溶解速率。 随着溶液开采的进行，高锂区域逐渐扩大，盐水中锂的浓度高达 120.4 mg/L，通常在 20-70 mg/L 之间。钾和锂分布之间的空间相关性表明，锂可以作为副产品进行有效回收。根据矿物分布和监测数据调整溶剂进样速率和浓度，对于优化生产过程中钾和锂的溶解效率至关重要。

description: Dark matter could have a dissipative asymmetric subcomponent in the form of atomic dark matter (aDM). This arises in many scenarios of dark complexity, and is a prediction of neutral naturalness, such as the Mirror Twin Higgs model. We show for the first time how White Dwarf cooling provides strong bounds on aDM. In the presence of a small kinetic mixing between the dark and SM photon, stars are expected to accumulate atomic dark matter in their cores, which then radiates away energy in the form of dark photons. In the case of white dwarfs, this energy loss can have a detectable impact on their cooling rate. We use measurements of the white dwarf luminosity function to tightly constrain the kinetic mixing parameter between the dark and visible photons, across many orders of magnitude in DM mass, down to values of $ε\sim 10^{-12}$. Using this method we can constrain scenarios in which aDM constitutes fractions as small as $10^{-3}$ of the total dark matter density. Our methods are highly complementary to other methods of probing aDM, especially in scenarios where the aDM is arranged in a dark disk, which can make direct detection extremely difficult but actually slightly enhances our cooling constraints.

description: As the United States is predicted to become the world's largest wine consuming nation by 2008 with consumers purchasing across all price segments, one might assume that Californian wineries should thrive in this market. However, regulations and consolidation effects often prevent small wineries from being able to reach the U.S. consumer and they face similar problems with exporting. These wineries must seek specialty distributors that represent lesser-known brands, usually by attending trade shows at great expense. In turn, specialty distributors face the daunting challenge of finding wineries that best satisfy their portfolios' needs. Given this problematic situation, can one provide assistance to these parties in their quest for finding appropriate partners? While this question no doubt has many positive answers, the approach we have chosen to explore is to develop a web-based matching program. We ask wineries and distributors to submit their respective attributes and their needs via a web questionnaire. Operations research methodology is then used to algorithmically determine the most promising partnerships, subject to mutual fit and based on constraints of supply, demand and avoidance of conflicting matches. We summarize the results obtained from the initial iteration of the program, a pre-qualification service created for the World Wine Market, a San Francisco trade show in 2004. We provide some of the participant feedback, including testimonials from parties that were successfully matched through the program. We also analyze the results to determine why the program did not recommend a greater number of matches and used this information and other feedback to assist in the development of the next program iteration While the conceptual contribution of our research is in providing the first documented application of "assignment problems" to model the optimal placement of wines into the distribution tier, this paper focuses instead on the potential practitioner contributions to the wine industry. A functional web based matching program could provide many small wineries with a means to expand their representation into additional markets domestically and internationally. Even if only a small fraction of the recommended matches take place, the business return from participation has enormous potential. We discuss the current improvements, which being funded through a Business and International Education Grant from the U.S. Department of Education. We conclude with ideas for future research, including extending this program to a broader range of participants.

description: The European Union is currently engaged in redesigning its trade relations with many of its partners in the Southern hemisphere. The present study assesses the economic implications of the negotiations of Economic Partnership Agreements between the European Union and ACP's regional groupings. These new trade arrangements, natural evolution of the Cotonou Agreements, represent an outstanding opportunity to favour the insertion of ACP countries into the world trade system and a genuine attempt to promote economic development and regional integration in developing world. Is this project bound to fail? Which are the prerequisites to make it work? Which lessons can be drawn from empirical evidences?

description: We consider a class of differential equations, $\ddot x + γ\dot x + g(x) = f(ωt)$, with $ω\in {\bf R}^{d}$, describing one-dimensional dissipative systems subject to a periodic or quasi-periodic (Diophantine) forcing. We study existence and properties of the limit cycle described by the trajectory with the same quasi-periodicity as the forcing. For $g(x)=x^{2p+1}$, $p\in {\bf N}$, we show that, when the dissipation coefficient is large enough, there is only one limit cycle and that it is a global attractor. In the case of other forces, including $g(x)=x^{2p}$ (with $p=1$ describing the varactor equation), we find estimates for the basin of attraction of the limit cycle.

description: The paper describes a two stage model of Hungarian households' food demand. Demand for the food aggregate is represented by a Working-Leser type single equation model while demand for seven distinct food types is modelled in a complete demand system using the LA/AIDS functional form. Estimation is based on household budget survey data for 1996. Demand elasticities are estimated for average households as well as for specific groups defined by sociodemographic characteristics. Fruit and vegetables are found to be the food types with most elastic demand but in general, differences between elasticities for different products as well as between different sociodemographic groups are relatively small.

description: "Brown dwarfs" is the collective name for objects more massive than giant planets such as Jupiter but less massive than M dwarf stars. This review gives a brief description of the classification and chemistry of low mass dwarfs. The current spectral classification of stars includes L and T dwarfs that encompass the coolest known stars and substellar objects. The relatively low atmospheric temperatures and high total pressures in substellar dwarfs lead to molecular gas and condensate chemistry. The chemistry of elements such as C, N, O, Ti, V, Fe, Cr, and the alkali elements play a dominant role in shaping the optical and infrared spectra of the "failed" stars. Chemical diagnostics for the subclassifications are described.

description: Im Zuge der Erlangung staatlicher Souveränität begannen in Weißrussland wirtschaftliche Restrukturierungsprozesse. Im Vergleich zu anderen ehemaligen Sowjetrepubliken blieben diese Reformbemühungen des Wirtschaftssystems von einer Plan- zur Marktorientierung jedoch sehr zaghaft und kamen bis Mitte der 1990er Jahre sogar fast vollständig zum Erliegen. Dieser Prozess ging mit dramatischen Produktionseinbrüchen insbesondere in der Landwirtschaft einher. Der insgesamt negative Trend ist nach wie vor anhaltend. Besonders betroffen ist die Fleischproduktion, da viele Haushalte ihre Nachfrage nach Fleischprodukten primär durch Subsistenzwirtschaft decken und daher ein erheblicher Teil der Nachfrage für die fleischproduzierenden Unternehmen weggebrochen ist. Diese Unternehmen sehen sich einer Fülle von Anpassungsschwierigkeiten gegenüber. Die institutionellen Rahmenbedingungen im Agrarsektor und insbesondere die Ausgestaltung flankierender ablaufpolitischer Maßnahmen sind für die landwirtschaftlichen Betriebe von existenzieller Bedeutung. Im Rahmen dieses Diskussionspapiers werden die Lage und Entwicklungsprobleme der weißrussischen Fleischwirtschaft unter besonderer Berücksichtigung der Rahmenbedingungen im Agrarsektor iskutiert. Die Ziele der Untersuchung waren es, die blaufenden Prozesse in der Fleischwirtschaft darzustellen, die Ursachen aufzudecken und Schlussfolgerungen für die Ausgestaltung der Agrarpolitik zu ziehen. Die Ergebnisse lassen darauf schließen, dass unvorteilhafte Situation der weißrussischen Fleischwirtschaft sowohl durch einen Rückgang der Produktionseffizienz in den Unternehmen und als auch durch das derzeit angewandte agrarpolitische Instrumentarium bedingt ist. Es bleibt abschließend festzustellen, dass eine grundlegende Änderung des wirtschafts- und agrarpolitischen Maßnahmenkatalogs erforderlich ist, um die wirtschaftliche Situation der Unternehmen in der Fleischwirtschaft zu verbessern und eine nachhaltige Entwicklung einzuleiten.

description: We present an unsupervised, local activation-dependent learning rule for intrinsic plasticity (IP) which affects the composition of ion channel conductances for single neurons in a use-dependent way. We use a single-compartment conductance-based model for medium spiny striatal neurons in order to show the effects of parametrization of individual ion channels on the neuronal activation function. We show that parameter changes within the physiological ranges are sufficient to create an ensemble of neurons with significantly different activation functions. We emphasize that the effects of intrinsic neuronal variability on spiking behavior require a distributed mode of synaptic input and can be eliminated by strongly correlated input. We show how variability and adaptivity in ion channel conductances can be utilized to store patterns without an additional contribution by synaptic plasticity (SP). The adaptation of the spike response may result in either "positive" or "negative" pattern learning. However, read-out of stored information depends on a distributed pattern of synaptic activity to let intrinsic variability determine spike response. We briefly discuss the implications of this conditional memory on learning and addiction.
