Cemeteries and the Decline of the Occult: From Ghosts to Memory in the Modern Age
Creators: name: Laqueur, Thomas
Publisher: name: Austrian Journal of Historical Studies
Year: 2003

description: New places for the dead - cemeteries - were from the start understood as places of memory in which the undead and sleepless dead, ghosts and spirits did not abide. Anxieties about the public health problems of old burial grounds were born of a new interest to separate the dead from the living; memory replaced the corpse as the placeholder for the deceased; a secular geography replaced a sacred one. The essay ends with the speculation that the popularity of the occult in late nineteenth century Europe might have been a response to the novel segregation of the dead.

description: For robust operation of high speed networks, wavelength conversion, as well as new signal processing and coding techniques are important. In this thesis, we model the propagation of an 80-Gb/s wavelength-converted signal gener- ated by utilizing cross-phase modulation (XPM) in a highly nonlinear fiber. We then compare the transmission performance of the wavelength-converted signal to that of the standard signal. After propagation over 1280 km or less, wavelength conversion adds no signal degradation in terms of BER. We conclude that wavelength conversion leads to no significant deterioration in a noise-limited propagation system.
Relativistic QRPA description of isoscalar compression modes in open-shell nuclei in the A$\approx$60 mass region

description: Very recent inelastic $α$-scattering data on the isoscalar monopole and dipole strength distributions in $^{56}$Fe, $^{58}$Ni, and $^{60}$Ni are analyzed in the relativistic quasiparticle random-phase approximation (RQRPA) with the DD-ME2 effective nuclear interaction (nuclear matter compression modulus K$_{nm}= 251$ MeV). In all three nuclei the calculation nicely reproduces the observed asymmetric shapes of the monopole strength, and the bimodal structure of the dipole strength distributions. The calculated centroid and mean energies are in very good qualitative agreement with the experimental values both for the monopole, and for the low- and high-energy components of the dipole transition strengths. It is noted, however, that while DD-ME2 reproduces in detail the excitation energies of the giant monopole resonances (GMR) in nuclei with $A \ge 90$, the theoretical centroids are systematically above the experimental values in lighter nuclei with $A \leq 60$. The latter can be reproduced with an effective interaction with a lower value of K$_{nm} \approx $ 230 MeV but, because of the asymmetric shapes and pronounced fragmentation of the monopole strength distributions, isoscalar GMR data in light nuclei cannot provide accurate estimates of the nuclear matter compression modulus.

description: Despite being a fundamental tool in soft matter research, quartz crystal microbalance (QCM) analyses of discrete macromolecules in liquid so far lack a firm theoretical basis. Currently, acoustic signals are qualitatively interpreted using ad-hoc frameworks based on effective electrical circuits, effective springs and trapped-solvent models with abundant fitting parameters. Nevertheless, due to its extreme sensitivity, the QCM technique pledges to become an accurate predictive tool. Using unsteady low Reynolds hydrodynamics we derive analytical expressions for the acoustic impedance of adsorbed discrete spheres. Our theory is successfully validated against 3D simulations and a plethora of experimental results covering more than a decade of research on proteins, viruses, liposomes, massive nanoparticles, with sizes ranging from few to hundreds of nanometers. The excellent agreement without fitting constants clearly indicates that the acoustic response is dominated by the hydrodynamic impedance, thus, deciphering the secondary contribution of physico-chemical forces will first require a hydrodynamic-reinterpretation of QCM.

description: Intelligent tutoring systems (ITSs) have been shown to be an effective supplementary teaching tool or aid for many domains.  Applying ITSs in open-ended domains such as computer programming is especially challenging, most notably when trying to assist with the process of programming itself.  Existing ITSs for programming focus on a very limited set of problems and concepts and are only useful early in an introductory CS course and a few limited places afterward.  Visual programming environments are another tool that have been used in introductory CS courses to help students learn basic concepts.  The key idea behind my work is the recognition of the importance of students' ability to read, understand, and trace code in order to write programs successfully.  A broader goal of my work is to show that an ITS based on a visual programming environment can be used to support students throughout an entire introductory CS course, without being severely constrained and limited to a small number of concepts and to low-level, simple tasks.  In my system, called RUR-ITS, students are given a program and are asked to predict the robot's behavior when running this program in a given environment.  RUR-ITS allows each problem to be assigned a difficulty level and multiple concepts that it involves within the conceptual model.  RUR-ITS can then use a problem selection algorithm to choose a problem that is most able to help the student master the concepts that they have not yet mastered.

description: Peer-to-peer(P2P) computing is emerging as a new distributed computing paradigm for novel applications that involves exchange of information among peers with little centralized coordination. Analyzing data distributed in P2P networks requires peer-to-peer data mining algorithms that can mine the data without data centralization. However, replicating result of centralized data mining in an exact fashion is often communication-wise expensive. Approximate algorithms can be a realistic and communication-efficient alternative in this case.This dissertation concentrates on developing approximate data mining algorithms suitable for P2P networks, that closely estimates the result of centralized data mining algorithm with probabilistic guarantee using minimal communication. The dissertation introduces the concept of approximate local algorithms that can estimate data mining result within desired accuracy boundary with user-specified probabilistic guarantee by operating within a spatial locality of the executioner-node. As a foundation of probabilistic approximation in P2P network, a random-walk based uniform data sampling approach is proposed, that removes the bias and dependence in sampling caused by varying degrees of connectivity and sizes of data shared. Then the sampling technique is applied to develop approximate local algorithms for solving the specific data mining problem of K-means clustering and frequent itemset mining in the context of P2P network. Two K-means clustering algorithms are developed, one of which extends the concept of centralized K-means algorithm to distributed dynamic peer-to-peer environment, while the other provides probabilistic guarantee on accuracy of clustering result in a static P2P network. A frequent itemset mining algorithm is developed as a direct application of the uniform data sampling technique that discovers most of the frequent itemsets with high probability using bounded communication. The main contribution of this research work is to introduce the concept of approximate local algorithms for data mining in P2P network that provides probabilistic guarantee of accuracy. It builds a basic tool for approximate data analysis in P2P network, a uniform data sampling technique, and develops communication efficient approximate local algorithms for mining data distributed in such network. The algorithms developed here provide data mining results within desired accuracy level and probabilistic guarantee, and shows good scalability with low communication overhead.

description: The values obtained experimentally for the conductivity critical exponent in numerous percolation systems, in which the interparticle conduction is by tunnelling, were found to be in the range of $t_0$ and about $t_0+10$, where $t_0$ is the universal conductivity exponent. These latter values are however considerably smaller than those predicted by the available ``one dimensional"-like theory of tunneling-percolation. In this letter we show that this long-standing discrepancy can be resolved by considering the more realistic "three dimensional" model and the limited proximity to the percolation threshold in all the many available experimental studies

Plebeian Spiritualism: Some Ambiguities of England's Enlightenment, Reformation, and Urbanisation
Creators: name: Barrow, Logie
Publisher: name: Austrian Journal of Historical Studies
Year: 2003

description: lt is superficial to speak of the occult as >post-Enlightenment.< The moderate Enlightenment had a basis in Newtonian physics which no >radical Enlightenment< ever claimed. The ambiguities of this physics fed occult activities into the 20th century. English plebeian spiritualists saw themselves as extending materialism into superfine or imponderable regions. Qualities conventionally associated with the >female< assumed a crucial role. Thus spiritualism restored the feminine to a centrality that it had not had in England since the death of the last Mary-substitute, Queen Elizabeth (1603). This restoration flourished most in newly industrialised areas of Northern England where, coincidentally or not, the impact of the 16th century formation had been notably superficial.

A Positive-Weight Next-to-Leading-Order Monte Carlo for Z Pair Hadroproduction

description: We present a first application of a previously published method for the computation of QCD processes that is accurate at next-to-leading order, and that can be interfaced consistently to standard shower Monte Carlo programs. We have considered Z pair production in hadron-hadron collisions, a process whose complexity is sufficient to test the general applicability of the method. We have interfaced our result to the HERWIG and PYTHIA shower Monte Carlo programs. Previous work on next-to-leading order corrections in a shower Monte Carlo (the MC@NLO program) may involve the generation of events with negative weights, that are avoided with the present method. We have compared our results with those obtained with MC@NLO, and found remarkable consistency. Our method can also be used as a standalone, alternative implementation of QCD corrections, with the advantage of positivity, improved convergence, and next-to-leading logarithmic accuracy in the region of small transverse momentum of the radiated parton.

description: Topological crystalline insulator tin telluride (SnTe) provides a rich playground to examine interactions of correlated electronic states, such as ferroelectricity, topological surface states, and superconductivity. Making SnTe into nanowires further induces novel electronic states due to one-dimensional (1D) confinement effects. Thus, for transport measurements, SnTe nanowires must be made narrow in their diameters to ensure the 1D confinement and phase coherence of the topological surface electrons. This study reports a facile growth method to produce narrow SnTe nanowires with a high yield using alloy nanoparticles as growth catalysts. The average diameter of the SnTe nanowires grown using the alloy nanoparticles is 85 nm, nearly a factor of three reduction from the previous average diameter of 240 nm using gold nanoparticles as growth catalysts. Transport measurements reveal the effect of the nanowire diameter on the residual resistance ratio and magnetoresistance. Particularly, the ferroelectric transition temperature for SnTe is observed to change systematically with the nanowire diameter. In situ cryogenic cooling of narrow SnTe nanowires in a transmission electron microscope directly reveals the cubic to rhombohedral structural transition, which is associated with the ferroelectric transition. Thus, these narrow SnTe nanowires represent a model system to study electronic states arising from the 1D confinement, such as 1D topological superconductivity as well as a potential multi-band superconductivity.

description: We report on a direct lattice calculation of the neutron EDM(NEDM) using the external electric field method in both quenched and full QCD. In quenched QCD, we use a $24^3\times 32$ lattice at $β=2.6$ with the Iwasaki gauge action and the clover fermion action to examine the viability of this method. In particular we investigate possible effects of violation of the periodic boundary condition of the external electric field on the NEDM signal. We also study the quark mass dependence of NEDM in quenched QCD, and observe that NEDM seems to remain non-zero toward the chiral limit because of the quenched artifact. In 2-flavor full QCD we employ configurations generated by the CP-PACS collaboration on a $24^3\times 48$ lattice at $β=2.1$ with the same gluon and quark actions as in the quenched case. Since the number of configurations is limited, we employ 8 different source points per one configuration and take an average over them. Our preliminary result at three quark masses ($m_{PS}/m_V\simeq 0.81, 0.76, 0.69$) indicates that non-zero value for NEDM can be obtained in full QCD. Statistical errors, however, are still too large to show the theoretically expected behaviour for NEDM in full QCD that it vanishes in the chiral limit.

description: Let $Γ$ be a simple graph of size $m$ and degree sequence $δ_1\ge δ_2\ge ... \ge δ_n$. Let ${\cal L}(Γ)$ denotes the line graph of $Γ$. The aim of this paper is to study mathematical properties of the alliance number, ${a}({\cal L}(Γ)$, and the global alliance number, $γ_{a}({\cal L}(Γ))$, of the line graph of a simple graph. We show that $\lceil\frac{δ_{n}+δ_{n-1}-1}{2}\rceil \le {a}({\cal L}(Γ))\le δ_1.$ In particular, if $Γ$ is a $δ$-regular graph ($δ>0$), then $a({\cal L}(Γ))=δ$, and if $Γ$ is a $(δ_1,δ_2)$-semiregular bipartite graph, then $a({\cal L}(Γ))=\lceil \frac{δ_1+δ_2-1}{2} \rceil$. As a consequence of the study we compare $a({\cal L}(Γ))$ and ${a}(Γ)$, and we characterize the graphs having $a({\cal L}(Γ))<4$. Moreover, we show that the global-connected alliance number of ${\cal L}(Γ)$ is bounded by $γ_{ca}({\cal L}(Γ)) \ge \lceil\sqrt{D(Γ)+m-1}-1\rceil,$ where $D(Γ)$ denotes the diameter of $Γ$, and we show that the global alliance number of ${\cal L}(Γ)$ is bounded by $γ_{a}({\cal L}(Γ))\geq \lceil\frac{2m}{δ_{1}+δ_{2}+1}\rceil$. The case of strong alliances is studied by analogy.

description: We recently developed a scheme to use low-cost calculations to find a single twist angle where the couple cluster doubles energy of a single calculation matches the twist-averaged coupled cluster doubles energy in a finite unit cell. We used initiator full configuration interaction quantum Monte Carlo ($i$-FCIQMC) as an example of an exact method beyond coupled cluster doubles theory to show that this selected twist angle approach had comparable accuracy in methods beyond coupled cluster. Further, at least for small system sizes, we show that the same twist angle can also be found by comparing the energy directly (at the level of second-order Moller-Plesset theory) suggesting a route toward twist angle selection which requires minimal modification to existing codes which can perform twist averaging.

Evidence for an Overluminosity of the Variable Star RR Lyr, and a Revised Distance to the LMC

description: We use theoretical models to establish a tight relationship for the absolute magnitudes of RR Lyrae stars as a function of their periods and Stroemgren pseudo-color c_0 = (u-v)_0 - (v-b)_0. Applying this to RR Lyr, and comparing the result with the predicted average absolute magnitude for stars of similar metallicity from the same models, yields an overluminosity of 0.064 +/- 0.013 mag in Stroemgren y (and thus similarly in V) for RR Lyr. Based on a revised value for RR Lyr's trigonometric parallax, and on a newly derived reddening value of E(B-V) = 0.015 +/- 0.020, we provide a corrected relationship between average absolute magnitude and metallicity for RR Lyrae stars that takes RR Lyr's evolutionary status fully into account for the first time. Applying this relationship to the LMC, we derive a revised true distance modulus of (m-M)_0 = 18.44 +/- 0.11.

description: Christopher Smart's prose journalism has been absurdly neglected in scholarship. Until very recently, Smart's journal The Midwife, or, the Old Woman's Magazine had rarely been granted any extensive research or scholarly exploration. Min Wild's 2008 publication, Christopher Smart and Satire: 'Mary Midnight' and the Midwife, was the first book to look at the journal in detail, while Smart's other journals, including the Student and Lilliputian, remain rarely read or studied in any depth. This thesis seeks to redress that neglect through a literary reading of the Midwife, and an historical contextualisation. The thesis investigates the work thematically and discusses some themes that have been neglected in scholarship on the Midwife. Where they overlap, or provide additional information, Smart's work in the Student, the Lilliputian, and the Universal Visiter are also considered. If possible I have suggested attributions for anonymous articles and correlated themes with Smart's better known works. In Chapter One, I have given an overview of the four journals with which Smart was associated as editor during the limited period of 1750-1753. I discuss the contributors and co-authors, as well as the publisher, John Newbery. In Chapter Two, I explore the influences on the creation of Mary Midnight, the purported editor of the Midwife, including her beginnings in the Student. Chapter Three discusses politics and gender in the Midwife, including the foreign politics within Richard Rolt's contributions. Chapter Four explores the Midwife's views on social issues of the time, and social justice. Overall, the thesis aims to open up the world of Mary Midnight and to understand the Midwife in relation to the culture in which it has a provenance.

description: Based on the method of collective variables we develop the statistical field theory for the study of a simple charge-asymmetric $1:z$ primitive model (SPM). It is shown that the well-known approximations for the free energy, in particular DHLL and ORPA, can be obtained within the framework of this theory. In order to study the gas-liquid critical point of SPM we propose the method for the calculation of chemical potential conjugate to the total number density which allows us to take into account the higher order fluctuation effects. As a result, the gas-liquid phase diagrams are calculated for $z=2-4$. The results demonstrate the qualitative agreement with MC simulation data: critical temperature decreases when $z$ increases and critical density increases rapidly with $z$.

description: Recent years have seen a confluence of two major trends - the increase of mobile devices such as smart phones as the primary access point to networked information and the rise of social media platforms that connect people. Their convergence supports the emergence of a new class of context-aware geo-social networking applications. While existing systems focus mostly on location, our work centers on models for representing and reasoning about a more inclusive and higher-level notion of context, including the user's location and surroundings, the presence of other people and devices, feeds from social networking systems they use, and the inferred activities in which they are engaged. A key element of our work is the use of collaborative information sharing where devices share and integrate knowledge about their context. This introduces the need for privacy and security mechanisms. We present a framework to provide users with appropriate levels of privacy to protect the personal information their mobile devices are collecting including the inferences that can be drawn from the information. We use Semantic Web technologies to specify high-level, declarative policies that describe user's information sharing preferences. We have built a prototype system that aggregates information from a variety of sensors on the phone, online sources, and sources internal to the campus intranet, and infers the dynamic user context. We show how our policy framework can be effectively used to devise better privacy control mechanisms to control information flow between users in such dynamic mobile systems.

description: Here we present an ab initio prediction of an order-disorder transition (ODT) from $I\bar{4}2d$-type to a Th$_3$P$_4$-type phase in the cation sublattices of Mg$_2$GeO$_4$, a post-post-perovskite (post-PPv) phase. This uncommon type of prediction is achieved by carrying out a high-throughput sampling of atomic configurations in a 56-atom supercell followed by a Boltzmann ensemble statistics calculation. Mg$_2$GeO$_4$ is a low-pressure analog of $I\bar{4}2d$-type Mg$_2$SiO$_4$, a predicted major planet-forming phase of super-Earths' mantles. Therefore, a similar ODT is anticipated in $I\bar{4}2d$-type Mg$_2$SiO$_4$ as well, which should impact the internal structure and dynamics of these planets. The prediction of this Th$_3$P$_4$-type phase in Mg$_2$GeO$_4$ enhances further the relationship between the crystal structures of Earth/planet-forming silicates and oxides at extreme pressures and those of rare-earth sesquisulfides at low pressures.

description: Understanding the nature of Dark Matter and Dark Energy is one of the most pressing issues in cosmology and fundamental physics. The purpose of the DUNE (Dark UNiverse Explorer) mission is to study these two cosmological components with high precision, using a space-based weak lensing survey as its primary science driver. Weak lensing provides a measure of the distribution of dark matter in the universe and of the impact of dark energy on the growth of structures. DUNE will also include a complementary supernovae survey to measure the expansion history of the universe, thus giving independent additional constraints on dark energy. The baseline concept consists of a 1.2m telescope with a 0.5 square degree optical CCD camera. It is designed to be fast with reduced risks and costs, and to take advantage of the synergy between ground-based and space observations. Stringent requirements for weak lensing systematics were shown to be achievable with the baseline concept. This will allow DUNE to place strong constraints on cosmological parameters, including the equation of state parameter of the dark energy and its evolution from redshift 0 to 1. DUNE is the subject of an ongoing study led by the French Space Agency (CNES), and is being proposed for ESA's Cosmic Vision programme.

Legitimate governance and statehood in Africa: beyond the failed state and colonial determination
Creators: name: Ezetah, Chinedu Reginald
Publisher: name: University of British Columbia
Year: 2009

description: This thesis looks at the problem of governance and statehood in Africa from an international law perspective. Adopting a comparative analytical research method, the thesis investigated the idea of statehood in traditional Africa and Europe, and highlighted conceptual differences. It traced the origin and nature of the post colonial African state to an oppressive and totalitarian colonial state; and the coalescence of international law with European civilization and reality. The argument is made that the international law framework on statehood and international solutions of intervention and democratization, are inadequate for dealing with the problems of statehood in Africa and its consequences such as state collapse. The thesis proposes the legitimization of the African post colonial state through a combination of a process of self determination and democratization. The pattern of self determination proposed seeks to give normative expression to an African state's reality by using the equilibrium of the peoples incorporation and disengagement from the state as an index for determining the role and relevance of the state. It is proposed that this index, in determining the ambits of the right to self determination of the constituent political units in a state, should entitle an African nation to a minimum of the right to self governance in a confederate system. In complimenting the foregoing legitimization process, the thesis proposes a democratic framework that is constructed on cultural foundations of endogenous democracy and development.

description: We study theories with SU(2|4) symmetry, which include the plane wave matrix model, 2+1 SYM on RxS^2 and N=4 SYM on RxS^3/Z_k. All these theories possess many vacua. From Lin-Maldacena's method which gives the gravity dual of each vacuum, it is predicted that the theory around each vacuum of 2+1 SYM on RxS^2 and N=4 SYM on RxS^3/Z_k is embedded in the plane wave matrix model. We show this directly on the gauge theory side. We clearly reveal relationships among the spherical harmonics on S^3, the monopole harmonics and the harmonics on fuzzy spheres. We extend the compactification (the T-duality) in matrix models a la Taylor to that on spheres.

description: We present a new determination of the parity of the neutral pion via the double Dalitz decay pi^0 -> e+ e- e+ e-. Our sample, which consists of 30511 candidate decays, was collected from K_L -> pi0 pi0 pi0 decays in flight at the KTeV-E799 experiment at Fermi National Accelerator Laboratory. We confirm the negative pi^0 parity, and place a limit on scalar contributions to the pi^0 -> e+ e- e+ e- decay amplitude of less than 3.3% assuming CPT conservation. The pi^0 gamma* gamma* form factor is well described by a momentum-dependent model with a slope parameter fit to the final state phase space distribution. Additionally, we have measured the branching ratio of this mode to be B(pi^0 -> e+ e- e+ e-) = (3.26 +- 0.18) x 10^(-5).

description: In this paper, we investigate the existence of Sierpiński numbers and Riesel numbers as binomial coefficients. We show that for any odd positive integer $r$, there exist infinitely many Sierpiński numbers and Riesel numbers of the form $\binom{k}{r}$. Let $S(x)$ be the number of positive integers $r$ satisfying $1\leq r\leq x$ for which $\binom{k}{r}$ is a Sierpiński number for infinitely many $k$. We further show that the value $S(x)/x$ gets arbitrarily close to 1 as $x$ tends to infinity. Generalizations to base $a$-Sierpiński numbers and base $a$-Riesel numbers are also considered. In particular, we prove that there exist infinitely many positive integers $r$ such that $\binom{k}{r}$ is simultaneously a base $a$-Sierpiński and base $a$-Riesel number for infinitely many $k$.
Crystallographic image processing for scanning probe microscopy

description: Scanning probe microscopy (SPM) images of regularly arranged spatially periodic objects can be processed crystallographically. The resulting information may be used to remove from the SPM image distortions that are due to a less than perfect imaging process. The combined effects of these distortions result in a point spread function that gives a quantitative measure of the performance of the microscope for a certain set of experimental conditions. On the basis of highly symmetric calibration samples, the point spread function of the microscope may be extracted and utilized for the correction of SPM images of unknowns that were recorded under essentially the same experimental conditions. We concentrate in this paper on more theoretical aspects of our method. A blunt scanning tunneling microscopy (STM) tip that consists of multiple mini-tips with electron orbital dimensions may be symmetrized on the basis of prior knowledge on the plane symmetry of a two-dimensional periodic array. This is illustrated with the crystallographic processing of a STM image of a regular array of fluorinated cobalt phthalocyanine molecules on graphite and backed up conceptually by simple simulations.

description: We describe a class of programmable devices that can discriminate between two quantum states. We consider two cases. In the first, both states are unknown. One copy of each of the unknown states is provided as input, or program, for the two program registers, and the data state, which is guaranteed to be prepared in one of the program states, is fed into the data register of the device. This device will then tell us, in an optimal way, which of the templates stored in the program registers the data state matches. In the second case, we know one of the states while the other is unknown. One copy of the unknown state is fed into the single program register, and the data state which is guaranteed to be prepared in either the program state or the known state, is fed into the data register. The device will then tell us, again optimally, whether the data state matches the template or is the known state. We determine two types of optimal devices. The first performs discrimination with minimum error, the second performs optimal unambiguous discrimination. In all cases we first treat the simpler problem of only one copy of the data state and then generalize the treatment to n copies. In comparison to other works we find that providing n > 1 copies of the data state yields higher success probabilities than providing n > 1 copies of the program states.

description: We report the development of a fiber-based, tunable optical cavity with open access. The cavity is of the Fabry-Perot type and is formed with miniature spherical mirrors positioned on the end of single- or multi-mode optical fibers by a transfer technique which involves lifting a high-quality mirror from a smooth convex substrate, either a ball lens or micro-lens. The cavities typically have a finesse of $\sim 1,000$ and a mode volume of 600 $μ$m$^3$. We demonstrate the detection of small ensembles of cold Rb atoms guided through such a cavity on an atom chip.

description: In light of the growing interest in the Hayward black hole solution, a detailed study on the corresponding lapse function and its roots is presented. The lapse function is expressed in terms of the classical Schwarzschild radius $r_s$ and the Hayward's parameter $l$. Both of these quantities are used as thermodynamic variables to find related thermodynamic quantities. In this context, the variable $l$ is associated with a canonical conjugate variable $\mathcal{F}_H$, and a free energy $Ξ$. Moreover, a second order phase transition is found to appears at $l\approx0.333\,r_s$.

description: We attempt to document complete energetic transactions of stars in their life. We calculate photon and neutrino energies that are produced from stars in their each phase of evolution from 1 to 8 M_sun, using the state-of-the-art stellar evolution code, tracing the evolution continuously from pre-main sequence gravitational contraction to white dwarfs. We also catalogue gravitational and thermal energies and helium, and heavier elements that are stored in stars and those ejected into interstellar space in each evolutionary phase.
