description: We explore the role played by the intrinsic decoherence in superconducting charge qubits in the presence of a microwave field applied as a magnetic flux. We study how the delayed creation of entanglement, which is opposite to the sudden death of entanglement, can be induced. We compute the time evolution of the population inversion, total correlation and entanglement, taking into account the junction mixed state and dissipation of the cavity field. We show that although decoherence destroys the correlation of the junction and field, information of the initial state may be obtained via quasi-probability distribution functions.

description: Modern software development frequently uses third-party packages, raising the concern of supply chain security attacks. Many attackers target popular package managers, like npm, and their users with supply chain attacks. In 2021 there was a 650% year-on-year growth in security attacks by exploiting Open Source Software's supply chain. Proactive approaches are needed to predict package vulnerability to high-risk supply chain attacks. The goal of this work is to help software developers and security specialists in measuring npm supply chain weak link signals to prevent future supply chain attacks by empirically studying npm package metadata. In this paper, we analyzed the metadata of 1.63 million JavaScript npm packages. We propose six signals of security weaknesses in a software supply chain, such as the presence of install scripts, maintainer accounts associated with an expired email domain, and inactive packages with inactive maintainers. One of our case studies identified 11 malicious packages from the install scripts signal. We also found 2,818 maintainer email addresses associated with expired domains, allowing an attacker to hijack 8,494 packages by taking over the npm accounts. We obtained feedback on our weak link signals through a survey responded to by 470 npm package developers. The majority of the developers supported three out of our six proposed weak link signals. The developers also indicated that they would want to be notified about weak links signals before using third-party packages. Additionally, we discussed eight new signals suggested by package developers.

An investigation of solvated electrons in hexamethylphosphoramide
Creators: name: Flynn, Garry John
Publisher: name: University of British Columbia
Year: 2010

description: This thesis is concerned with a detailed investigation of the nature, yield, stability, and reactivity of solvated electrons in hexamethylphosphoramide (HMPA). Evidence is presented for their formation by radiolysis and for their comparatively long-lived existence in this highly polar aprotic solvent in which ordinary anions are particularly weakly solvated. By means of microsecond pulse radiolysis methods it was shown that the solvated electron in HMPA has a intense broad structureless absorption band with a band maximum at 2200 ± 100 nm, a band half-width of 3600 cm⁻¹ and maximum molar absorptivity of (3.2 + 0.5) X 10⁴ M⁻¹ cm⁻¹. The spectrum is similar to that found in solutions of sodium metal dissolved in HMPA. Radiolysis studies provided a value of 2.2 ± 0.2 for the free-ion yield of solvated electrons. This was established by both pulse and steady-state methods and is approximately what one would expect on the basis of the liquid's dielectric constant when compared with other solvents. An interesting deduction from the steady-state Ɣ-radiolysis results was that N₂O does not scavenge electrons on a one-to-one basis in this solvent, but rather produced more than one N₂ molecule per electron scavenged. The yields of N₂ from N₂O scavenging of electrons in HMPA/water mixtures are also reported for the full composition range. Electron decays were studied spectro-photometrically and its rate of reaction with N₂O, pyrene, anthracene and other additives are reported in the thesis. When stable solutions of solvated electrons in HMPA (alkali metal solutions) were themselves irradiated, a net decrease in electron concentration occurred, indicating that e⁻HMPA reacts not only with its concomitant positive ion but also with other radiolysis products. Pure HMPA produces hydrogen and methane when irradiated, with yields of 3.3 ± 0.3 and 0.29 ± 0.03 respectively. The H₂ yield was shown to comprise a non-scavengable molecular process (whose yield is 1.4 ± 0.1) and a scavengable part (yield 1.9 ± 0.2) that clearly involved solvated electrons.

description: In the Netherlands, two new political parties have emerged within the last decade
against the rising influence of right-wing populism. DENK and NIDA, founded by mainly
Dutch Muslims with a migration background, have increasingly countered right-wing
rhetoric in Dutch politics (verrechtsing) in which Islam is problematized. The role of media
is fundamental in understanding these parties and their success in politics, as they
are known for the ways they use social media as a venue for political and social engagement
and their critical attitude towards mainstream media. In this article, I explore
the relationship between DENK and NIDA and mainstream media, and analyze some of
the ways DENK and NIDA use social media platforms to foster resistance to dominant
narratives on Islam and Muslims in Dutch society. This analysis shows that social media
function as “third spaces” where these parties can “talk back” and discuss issues
that concern Muslims, breaking free from places where their voices are marginalized.

description: Transformation of disks into spheroids via mergers is a well-accepted element of galaxy formation models. However, recent simulations have shown that bulge formation is suppressed in increasingly gas-rich mergers. We investigate the global implications of these results in a cosmological framework, using independent approaches: empirical halo-occupation models (where galaxies are populated in halos according to observations) and semi-analytic models. In both, ignoring the effects of gas in mergers leads to the over-production of spheroids: low and intermediate-mass galaxies are predicted to be bulge-dominated (B/T~0.5 at <10^10 M_sun), with almost no bulgeless systems), even if they have avoided major mergers. Including the different physical behavior of gas in mergers immediately leads to a dramatic change: bulge formation is suppressed in low-mass galaxies, observed to be gas-rich (giving B/T~0.1 at <10^10 M_sun, with a number of bulgeless galaxies in good agreement with observations). Simulations and analytic models which neglect the similarity-breaking behavior of gas have difficulty reproducing the strong observed morphology-mass relation. However, the observed dependence of gas fractions on mass, combined with suppression of bulge formation in gas-rich mergers, naturally leads to the observed trends. Discrepancies between observations and models that ignore the role of gas increase with redshift; in models that treat gas properly, galaxies are predicted to be less bulge-dominated at high redshifts, in agreement with the observations. We discuss implications for the global bulge mass density and future observational tests.

description: Increasingly larger number of software systems today are including data science components for descriptive, predictive, and prescriptive analytics. The collection of data science stages from acquisition, to cleaning/curation, to modeling, and so on are referred to as data science pipelines. To facilitate research and practice on data science pipelines, it is essential to understand their nature. What are the typical stages of a data science pipeline? How are they connected? Do the pipelines differ in the theoretical representations and that in the practice? Today we do not fully understand these architectural characteristics of data science pipelines. In this work, we present a three-pronged comprehensive study to answer this for the state-of-the-art, data science in-the-small, and data science in-the-large. Our study analyzes three datasets: a collection of 71 proposals for data science pipelines and related concepts in theory, a collection of over 105 implementations of curated data science pipelines from Kaggle competitions to understand data science in-the-small, and a collection of 21 mature data science projects from GitHub to understand data science in-the-large. Our study has led to three representations of data science pipelines that capture the essence of our subjects in theory, in-the-small, and in-the-large.

L'abuso del Diritto nel contesto del Diritto Tributario Comparato: analisi dei sistemi giuridici della Federazione Brasiliana e dell'Unione Europea
Creators: name: Oliveira, Cecilia Teixeira De Souza <1976>

Subjects: IUS/12 Diritto tributario

description: La tesi svolge il tema dell'abuso del diritto nell'ambito del diritto tributario comparato. Vengono individuati due limiti nella trattazione dell'argomento: l'oggetto di studio è il fenomeno abusivo riguardante esclusivamente il diritto tributario e specificamente nell'ottica comparativa dei due ordinamenti giuridici comunitario e brasiliano. Questi ultimi rivelano un importante punto comune: la distribuzione orizzontale del potere tributario. Di conseguenza una parte della tesi analizza gli ordinamenti giuridici con divisione orizzontale di potere. Con lo scopo di svolgere quest'ultima analisi, viene trattato il concetto di potestà tributaria e dei suoi elementi costitutivi, nonché della strutturazione della potestà  tributaria sia in Brasile sia nell'Unione Europea, due contesti in cui un potere centrale esercita influenza anche sugli enti detentori del potere. In questo senso vengono esposti lo storico della potestà  tributaria brasiliana, le considerazioni teoriche sul federalismo fiscale e l'assetto di quest'ultimo nel Brasile odierno; d'altra parte, riguardo all'Unione Europea, sono presentate l'analisi del concetto di sovranità  e la divisione del potere nell'ambito dell'Unione Europea, in specifico del potere tributario. Dopo aver mostrato i punti di convergenza e divergenza di questi due ordinamenti, si passa ad esaminare l'abuso del diritto come fenomeno nell'ambito tributario. Quindi si esamina la disciplina giuridica dell'abuso di diritto nel diritto tributario in entrambi ordinamenti, partendo da un excursus storico, sia in un'ottica generale sia in quella specifica del diritto tributario, ed esaminando le modalità  di abuso del diritto con riflessi tributari. Finite le suddette analisi, è stato possibile trarre conclusioni nella direzione della ricostruzione dogmatica tributaria sull'abuso di diritto in entrambi i sistemi, suggerendo elementi per l'ottimizzazione di tale disciplina.

description: In cosmology, the analysis of observational evidence is very important to test theoretical models of the Universe. Artificial neural networks are powerful and versatile computational tools for data modelling and are recently being considered in the analysis of cosmological data. The main goal of this paper is to provide an introduction to artificial neural networks and to describe some applications to cosmology. We present an overview on the fundamentals of neural networks and their technical details. Throughout three examples, we show their capabilities in modelling cosmological data, saving computational time in numerical tasks, and classifying stellar objects. Artificial neural networks offer interesting qualities that make them a viable alternative method for data analysis in cosmological research.

description: We consider controlled collisions between two ultracold atoms guided by external harmonic potentials. We derive analytical solutions of the Schroedinger equation for this system, and investigate the properties of eigenergies and eigenstates for different trap geometries as a function of a trap separation and of the scattering length. When varying the trap separation the energy spectrum exhibits avoided crossings, corresponding to trap-induced shape resonances. Introducing an energy-dependent scattering length we investigate the behavior of the system in the vicinity of a magnetic Feshbach resonance. Finally, we illustrate our analytical results with two examples: the quantum phase gate controlled by the external magnetic field, and a scheme for a coherent transport of atoms in optical lattices into higher Bloch bands.

The limit of the speeds at the homogenization limit is proved rigorously. Near this limit, generically, the fronts move faster when the spatial period is enlarged, but the speeds vary only at the second order. The dependence of the speeds on habitat fragmentation is also analyzed in the case of the patch model.

description: In the classical cop and robber game, two players, the cop C and the robber R, move alternatively along edges of a finite graph G. The cop captures the robber if both players are on the same vertex at the same moment of time. A graph G is called cop win if the cop always captures the robber after a finite number of steps. Nowakowski, Winkler (1983) and Quilliot (1983) characterized the cop-win graphs as graphs admitting a dismantling scheme. In this paper, we characterize in a similar way the class CW(s,s') of cop-win graphs in the game in which the cop and the robber move at different speeds s' and s, s'<= s. We also establish some connections between cop-win graphs for this game with s'=3, coincide and we provide a structural characterization of these graphs. We also investigate several dismantling schemes necessary or sufficient for the cop-win graphs in the game in which the robber is visible only every k moves for a fixed integer k>1. We characterize the graphs which are cop-win for any value of k. Finally, we consider the game where the cop wins if he is at distance at most 1 from the robber and we characterize via a specific dismantling scheme the bipartite graphs where a single cop wins in this game.

description: One of the central questions about the iron pnictides concerns the extent to which their electrons are strongly correlated. Here we address this issue through the phenomenology of the charge transport and dynamics, single-electron excitation spectrum, and magnetic ordering and dynamics. We outline the evidence that the parent compounds, while metallic, have electron interactions that are sufficiently strong to produce incipient Mott physics. In other words, in terms of the strength of electron correlations compared to the kinetic energy, the iron pnictides are closer to intermediately-coupled systems lying at the boundary between itinerancy and localization, such as V2O3 or Se-doped NiS2, rather than to simple antiferromagnetic metals like Cr. This level of electronic correlations produces a new small parameter for controlled theoretical analyses, namely the fraction of the single-electron spectral weight that lies in the coherent part of the excitation spectrum. Using this expansion parameter, we construct the effective low-energy Hamiltonian and discuss its implications for the magnetic order and magnetic quantum criticality. Finally, this approach sharpens the notion of magnetic frustration for such a metallic system, and brings about a multiband matrix t-J1-J2 model for the carrier-doped iron pnictides.

description: We present magnetization measurements carried out on polycrystalline and single-crystalline samples of $α$-Li$_2$IrO$_3$ under hydrostatic pressures up to 2 GPa and establish the temperature-pressure phase diagram of this material. The Néel temperature ($T_{\rm{N}}$) of $α$-Li$_2$IrO$_3$ is slightly enhanced upon compression with $dT_{\rm{N}}/dp$ = 1.5 K/GPa. Above 1.2 GPa, $α$-Li$_2$IrO$_3$ undergoes a first-order phase transition toward a nonmagnetic dimerized phase, with no traces of the magnetic phase observed above 1.8 GPa at low temperatures. The critical pressure of the structural dimerization is strongly temperature-dependent. This temperature dependence is well reproduced on the ab initio level by taking into account lower phonon entropy in the nonmagnetic phase. We further show that the initial increase in $T_{\rm{N}}$ of the magnetic phase is due to a weakening of the Kitaev interaction $K$ along with the enhancement of the Heisenberg term $J$ and off-diagonal anisotropy $Γ$. Our study reveals a common thread in the interplay of magnetism and dimerization in pressured Kitaev materials.

description: The origin of the low-temperature ferromagnetic instability in YTiO3 driven by the interplay between lattice, orbital, spin, and charge degrees of freedom is on the background of lattice dynamics. We present a comprehensive study of temperature-dependent polarized Raman scattering in a nearly stoichiometric orthorhombic YTiO3 single crystal. The lattice-dynamics calculations authenticate the assignment for the observed Ag- and B2g-symmetry modes in terms of the atoms vibrational patterns. The obtained results suggest that trigonal GdFeO3-type distortions become unstable against tetragonal Jahn-Teller distortions, leading to the consequent orbital structure refinement and ferromagnetic ground state in YTiO3.

Photoelectron spectroscopy of some polyatomic molecules
Creators: name: Chau, Foo-Tim
Publisher: name: University of British Columbia
Year: 2010

description: The photoelectron spectrum of a molecule displays the kinetic energy distribution of the ejected photoelectron by monochromatic radiation. From the fine structure on a photoelectron band, valuable information about the bonding properties of both the molecule and its cation, and the ionic geometry can be obtained. The work described in this thesis falls into two main parts. The first is concerned with the quantitative application of the Franck-Condon principle to group VI hydrides, nitrous oxide and dihaloethylenes, by which the geometries of their molecular ions were obtained. An iterative method was devised to facilitate the computational procedure. The second part of this thesis contains the results of photoelectron spectroscopic studies on several halogenated molecules, viz. fluorotribromo-methane, fluorotrichloromethane, 1,2-dichloro-, 1,2 dibromo-, and 1,2 diiodo-ethanes and their perfluoro derivatives, 1,2 bromochloroethane, 1,2-dibromo-1,1-difluoroethane, cis and trans 1,2 difluoroethylenes, and 1,2 dibromo-cyclohexane. One electron models including spin orbital coupling, and through bond and through space interactions, are applied to most of these molecules as well as the dichloro-, dibromo-, and diiodoethylenes. The NMR chemical shifts, nuclear quadrupole coupling constants, electronegativity of the halogen atom and the force constants of the molecules studied are discussed in the light of the calculated molecular orbital parameters.
Max Weber in the United States
Creators: name: Scaff, Lawrence A.
Publisher: name: Università degli Studi di Firenze
Year: 2014

description: In his contribution L. Scaff outlines the reception history of Max Weber’s work from its beginnings down to the present. It highlights the importance of the first translations, including those by prominent American authors and particularly those who had studied in Germany; and then in the post-war years the role of emigrants familiar with Weber’s work. The establishment of Weber texts as compulsory reading in the curricula of American colleges also played a significant role. The striking readiness, even ease, with which Weber was received in America is something Scaff deduces from three “narratives that captured the imagination of the American audience”. The first is the narrative of voluntarism, i.e. “the way in which Weber developed his conception of the sect and its effects on the individual and society”. Next is the narrative of achievement, in the sense of “mastery of the world”, preceded by “mastery of the self”, which “when put into practice entailed the conquest of the New World’s primordial wilderness”. Finally there is the narrative of redemption as “the most potent founding myth of the American experience”: “The quest for salvation that began as a religiously inspired message became transformed into a secularized cultural theme: the search for the possibility of breaking free from constraints in order to create a better life, to renew the self, to gain a second chance by atoning for moral failures, and to find reconciliation with God, humankind, and the world.”

Although intercellular communications between these endocrine cells have recently been observed, their roles in glucose homeostasis have not been clearly understood. In this study, we construct a mathematical model for an islet consisting of two-state alpha-, beta-, and delta-cells, and analyze effects of known chemical interactions between them with emphasis on the combined effects of those interactions. In particular, such features as paracrine signals of neighboring cells and cell-to-cell variations in response to external glucose concentrations as well as glucose dynamics, depending on insulin and glucagon hormone, are considered explicitly. Our model predicts three possible benefits of the cell-to-cell interactions: First, the asymmetric interaction between alpha- and beta-cells contributes to the dynamic stability while the perturbed glucose level recovers to the normal level. Second, the inhibitory interactions of delta-cells for glucagon and insulin secretion prevent the wasteful co-secretion of them at the normal glucose level. Finally, the glucose dose-responses of insulin secretion is modified to become more pronounced at high glucose levels due to the inhibition by delta-cells. It is thus concluded that the intercellular communications in islets of Langerhans should contribute to the effective control of glucose homeostasis.

description: We discuss the origin of the dramatically different X-ray spectral shapes observed in the Low Hard State (LHS: dominated by thermal comptonisation) and the High Soft State (HSS: dominated by the accretion disc thermal emission and non-thermal comptonisation in the corona). We present numerical simulations using a new code accounting for the so-called synchrotron boiler effect. These numerical simulations when compared to the data allow us to constrain the magnetic field and temperature of the hot protons in the corona. For the hard state of Cygnus X-1 we find a magnetic field below equipartition with radiation, suggesting that the corona is not powered through magnetic field dissipation (as assumed in most accretion disc corona models). On the other hand, our results also point toward proton temperatures that are substantially lower than typical temperatures of the ADAF models. Finally, we show that in both spectral states Comptonising plasma could be powered essentially through power-law acceleration of non-thermal electrons, which are then partly thermalised by the synchrotron and Coulomb boiler. This suggests that, contrary to current beliefs, the corona of the HSS and that of the LHS could be of very similar nature. The differences between the LHS and HSS coronal spectra would then be predominantly caused by the strong disc soft cooling emission which is present in the HSS and absent in the LHS.

description: With both three-nucleon force and continuum coupling included, we have developed a self-consistent {\it ab initio} Gamow shell model within the Gamow Hartree-Fock (GHF) basis obtained by the realistic interaction itself. With the chiral two-nucleon N$^3$LO and three-nucleon N$^2$LO interactions, the Gamow shell model has been applied to the mirror systems of $Z=8$ neutron-rich isotopes and $N=8$ proton-rich isotones, giving good agreements with data in binding energies, dripline positions and excitation spectra. The GHF calculated that the $0d_{3/2}$, $1s_{1/2}$ and $1p_{3/2}$ orbitals are resonances. The resonance states and their interplay with nonresonant continua play a crucial role in the descriptions of nuclei around driplines. Excitation spectra and Thomas-Ehrman shifts observed can be better described when both three-nucleon force and continuum coupling are considered in calculations. The three-nucleon force and continuum coupling produce a combined effect on the Thomas-Ehrman shift, e.g., for the ${1/2}^+$ resonance level of $^{19}$Na. The calculations help the understandings of related nuclear astrophysical processes.

description: The properties of pairing correlations in symmetric nuclear matter are studied in the relativistic mean field (RMF) theory with the effective interaction PK1. Considering well-known problem that the pairing gap at Fermi surface calculated with RMF effective interactions are three times larger than that with Gogny force, an effective factor in the particle-particle channel is introduced. For the RMF calculation with PK1, an effective factor 0.76 give a maximum pairing gap 3.2 MeV at Fermi momentum 0.9 fm$^{-1}$, which are consistent with the result with Gogny force.

description: We study the evolution of the Gregory-Laflamme instability for black strings in global AdS spacetime, and investigate the CFT dual of the formation of a bulk naked singularity. Using an effective theory in the large D limit, we uncover a rich variety of dynamical behaviour, depending on the thickness of the string and on initial perturbations. These include: large inflows of horizon generators from the asymptotic boundary (a `black tsunami'); a pinch-off of the horizon that likely reveals a naked singularity; and competition between these two behaviours, such as a nakedly singular pinch-off that subsequently gets covered by a black tsunami. The holographic dual describes different patterns of heat flow due to the Hawking radiation of two black holes placed at the antipodes of a spherical universe. We also present a model that describes, in any D, the burst in the holographic stress-energy tensor when the signal from a bulk self-similar naked singularity reaches the boundary. The model shows that the shear components of the boundary stress diverge in finite time, while the energy density and pressures from the burst vanish.

description: New results from a large survey of H-alpha emission-line galaxies at z=0.84 using WFCAM/UKIRT and a custom narrow-band filter in the J band are presented as part of the HiZELS survey. Reaching an effective flux limit of 1e-16 erg/s/cm^2 in a comoving volume of 1.8e5 Mpc^3, this represents the largest and deepest survey of its kind ever done at z~1. There are 1517 potential line emitters detected across 1.4 sq.deg of the COSMOS and UKIDSS UDS fields, of which 743 are selected as H-alpha emitters. These are used to calculate the H-alpha luminosity function, which is well-fitted by a Schechter function with phi*=10^(-1.92+-0.10) Mpc^-3, L*=10^(42.26+-0.05)erg/s, and alpha=-1.65+-0.15. The integrated star formation rate density (SFRD) at z=0.845 is 0.15+-0.01 M_sun/yr/Mpc^3. The results robustly confirm a strong evolution of SFRD from the present day out to z~1 and then flattening to z~2, using a single star-formation indicator. Out to z~1, both the characteristic luminosity and space density of the H-alpha emitters increase significantly; at higher redshifts, L* continues to increase, but phi* decreases. The z=0.84 H-alpha emitters are mostly disk galaxies (82+-3%), while 28+-4% of the sample show signs of merger activity and contribute ~20% to the total SFRD. Irregulars and mergers dominate the H-alpha luminosity function above L*, while disks are dominant at fainter luminosities. These results demonstrate that it is the evolution of 'normal' disk galaxies that drives the strong increase in the SFRD from the current epoch to z~1, although the continued strong evolution of L* beyond z=1 suggests an increasing importance of merger activity at higher redshifts.

description: We describe an efficient scheme for evaluating higher order contributions to primordial cosmological perturbations using the "in-in" formalism, which is the basis of modern calculations of non-Gaussian and higher order contributions to the primordial spectrum. We show that diagrams with two or more vertices require careful handling. We present an implementation of the operator formalism in which these diagrams can be evaluated in a simple and transparent fashion. We illustrate our methodology by evaluating the correction to the primordial gravitational wave spectrum generated by scalar loops, a 2-vertex, 1-loop interaction. We then look at a generalized $N$-point, 2-vertex diagram.

The synthesis and reactivity of tetracyclo [3.3.1.1³‧⁷.0¹‧³] decane
Creators: name: Thorpe, Edward John
Publisher: name: University of British Columbia
Year: 2010

description: The structures and some properties of adamantane (1b), strained cyclopropanes (23), and certain small ring propeller-like molecules (28) are reviewed. The synthesis of a new type of compound containing a combination of such structures and properties is presented. This compound tetracyclo [3.3.1.1³‧⁷.0¹‧³] decane or more simply 1,3-dibromoadamantane (DHA) contains a very strained cyclopropyl group within an adamantane skeleton and was produced by bonding two bridgehead (tertiary) carbons together across the normally extremely rigid structure of adamantane. In the synthesis of DHA using alkali metal (or alloys) with 1,3-dibromoadamantane (37), the reaction times and relative yields of adamantane and DHA were extremely variable. The former difficulty was resolved by the addition of an initiator (usually ṯ-butyl alcohol), while the yields were increased and made consistent by substituting sodium naphthalide or ṉ-butyl lithium - hexamethylphosphoramide for the alkali metals. DHA and adamantane were also isolated as the major products from the reaction of 1,3,5-tri- and 1,3,5,7-tetrabromoadamantane with alkali metals or alloys. DHA is one of the few organic molecules which possesses a so-called inverted geometry about the internally bonded bridgehead (quaternary) carbons. Wiberg, Hiatt and Burgmaier⁵⁵ have defined an inverted carbon as one "in which all atoms joined to the bridgehead atoms (inverted carbons) lie in one hemisphere, (i.e. in one plane or on one side of a plane passing through the bridgehead atoms)." The inversion of the DHA bridgehead carbons results in a highly strained bond and an unusually great reactivity for a formally saturated hydrocarbon. DHA reacts spontaneously with oxygen at room temperature to give a peroxy polymer Ad - O ≁ O - Ad – O ≁[sub x] O-Ad which explodes at ca. 146°C. DHA also reacts rapidly with halogens, acids, and mercuric acetate to yield halides, esters and alcohols, alcohols is slow (more than 24 hr to complete), Lewis acid catalysts promoted rapid addition of both alcohols (to give ethers) and benzene (to give phenylated adamantanes). Adam's catalyst promoted the rapid (30 min) addition of hydrogen to DHA in n-heptane solution to produce adamantane. In the solid phase DHA polymerized readily at ca. 160°C to give a highly insoluble product, polyadamantane Ad-(Ad)[sub x] -Ad which possesses great thermal stability (decomposition point ca. 500°C under nitrogen). In ṉ-octane solution under nitrogen the half life of DHA was 4,45 hr at 195°C, The reaction of DHA with halogens in ether gives (3-halo-1-adamantanyl)-diethyl oxonium trihalide. The reaction of this unstable intermediate with nucleophiles, for example H₂O or NaCN, is discussed as a potential source of unsym-metrical 1,3-disubstituted adamantane derivatives.
