Hole core in superconductors and the origin of the Spin Meissner effect

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: It is proposed that superconductors possess a hidden `hole core' buried deep in the Fermi sea. The proposed hole core is a small region of the Brillouin zone (usually at the center of the zone) where the lowest energy states in the normal state reside. We propose that in the superconducting state these energy states become {\it singly occupied} with electrons of a definite spin helicity. In other words, that holes of a definite spin helicity condense from the top to the bottom of the band in the transition to superconductivity, and electrons of that spin helicity `float' on top of the hole core, thus becoming highly mobile. The hole core has radius $q_0=1/2λ_L$, with $λ_L$ the London penetration depth, and the electrons expelled from the hole core give an excess negative charge density within a London penetration depth of the real space surface of the superconductor. The hole core explains the development of a spin current in the transition to superconductivity (Spin Meissner effect) and the associated negative charge expulsion from the interior of metals in the transition to superconductivity, effects we have proposed in earlier work to exist in all superconductors and to be at the root of the Meissner effect.

description: The nucleation of cavities in a homogenous polymer under tensile strain is investigated in a coarse-grained molecular dynamics simulation. In order to establish a causal relation between local microstructure and the onset of cavitation, a detailed analysis of some local properties is presented. In contrast to common assumptions, the nucleation of a cavity is neither correlated to a local loss of density nor, to the stress at the atomic scale and nor to the chain ends density in the undeformed state. Instead, a cavity in glassy polymers nucleates in regions that display a low bulk elastic modulus. This criterion allows one to predict the cavity position before the cavitation occurs. Even if the localization of a cavity is not directly predictable from the initial configuration, the elastically weak zones identified in the initial state emerge as favorite spots for cavity formation.
Stakeholders' perception on the applicability of shared value creation in Mongolian mining development

description: In recent decades, world population growth has resulted in an unprecedented rise in consumer demand for goods and commodities, and has resultantly triggered the rapid development of relevant industries, including the mining sector. Site-specific effects of the rapid industrial development have led to environmental issues and mounting social dissatisfaction, and have created major obstacles for the industry. Weak governance, an unstable regulatory environment and ill-defined public expectations are considerations that should all be taken into account in order to better understand the current dynamics. Researchers, scientists and business owners are looking for ways to effectively mitigate some of the non-technical challenges facing the industry, proposing various tools, approaches and innovative ideas to moderate risks and to assist with collaboration. One idea gaining momentum is the “Shared Value” approach, which is the subject of this thesis. This research explores the applicability of the Shared Value approach within the Mongolian context. This research focuses on the mining industry’s impact on Mongolia’s development, the negative effects of which have mainly been caused by the unequal distribution of the mining wealth over the last 25 years, analyzes and identifies factors which have led to current social and political issues faced within Mongolia, and which can be traced back to the development of the mining sector. The current situation regarding public perceptions and expectations in Mongolia are based on a survey of the major mining stakeholders. The results of this survey will help us understand the public expectations held in Mongolia with respect to mining development, and these considerations will be taken into account in the development of future strategies. The case study of the situation in Mongolia offers us a unique opportunity to study the development of the mining industry in a country with a highly educated population that is endowed with vast untapped natural resources, and yet which is unable to fully benefit from these advantages because of weak governance, appropriate or inappropriate governmental regulations, mining projects with disastrous environmental and social impacts, and the often one-sided and polarized involvement of civil societies.
CHARACTERIZATION OF THE AMINO ACIDS MEDIATING THE INTERACTION BETWEEN HSPA1A AND LIPIDS

description: HspA1A is a stress-inducible molecular chaperone that plays a critical role in protein homeostasis and cell survival. HspA1A anchors to and embeds in membranes by interaction with anionic lipids such as phosphatidylserine (PS). HspA1A has no known lipid binding (LBDs) or transmembrane domains. In this thesis, we sought to define the LBDs for PS on HspA1A. We hypothesized that the HspA1A-PS is a two-step process: the initial docking of the nucleotide binding domain (NBD) to the membrane, which triggers allosteric changes orienting the substrate binding domain (SBD) into a position to insert into the membrane. We used computational modelling to simulate the HspA1A-PS to define potential PS-binding regions on HspA1A and inform experiments to further define these regions. We identified several potential regions of PS interaction, but these regions differed based on the simulation parameters and no consensus region was identified. We incubated HspA1A with BAG and DNAJ to determine whether these co-chaperones alter lipid binding. DNAJ showed no change in lipid binding, while BAG increased HspA1A binding to all lipids tested. Mutations on HspA1A were generated for residues F353 and Q376, known to affect the allosteric communication between the NBD and SBD, but these mutants did not change binding to PS. Cryo-electron microscopy (Cryo-EM) and cell surface biotinylation were used to determine the orientation of HspA1A in PS-containing artificial membranes and cellular plasma membrane, respectively. Cryo-EM could not resolve the orientation of HspA1A at the membrane but suggests that HspA1A may favor increased curvature of the membrane tending to oligomerize at the membrane. Cell surface biotinylation identified four regions on HspA1A that may be exposed to the extracellular milieu but did not identify any changes based on heat-shock status or recovery time.

description: An odd-odd nucleus is treated as the core-particle-hole system. The core is described by the Bohr Hamiltonian. Different collective potentials of the core are investigated. The odd particle and hole are assumed to be in the symmetric [proton h11/2]x[neutron hole h11/2] configuration. Signatures of chirality in the odd-odd nucleus spectra are observed. The sufficient condition for the appearance of signatures of chirality in the core-particle-hole system is the alpha-symmetry of the core provided the particle-hole configuration of the odd valence particles is symmetric.

description: A duality between the large N 't Hooft limit of the WD_N minimal model CFTs and a higher spin gravity theory on AdS3 is proposed. The gravity theory has massless spin fields of all even spins s=2,4,6,..., as well as two real scalar fields whose mass is determined by the 't Hooft parameter of the CFT. We show that, to leading order in the large N limit, the 1-loop partition function of the higher spin theory matches precisely with the CFT partition function.

description: The interaction between the cosmon and neutrinos may solve the "why now problem" for dark energy cosmologies. Within growing neutrino quintessence it leads to the formation of nonlinear neutrino lumps. For a test of such models by the integrated Sachs-Wolfe effect for the cosmic microwave background (CMB) we estimate the size and time evolution of the gravitational potential induced by these lumps. A population of lumps with size of 100 Mpc or more could lead to observable effects on the CMB anisotropies for low angular momenta. The linear approximation is found to be invalid for the relevant length scales. Quantitative estimates depend strongly on the details of the transition between the linear and nonlinear regimes. In particular, important backreaction effects arise from the nonlinearities of the cosmon interactions. At the present stage the uncertainties of the estimate make it difficult to constrain the parameter space of growing neutrino models. We explicitly discuss scenarios and models that are compatible with the CMB observations.

description: The coexistence curves of liquid-liquid equilibrium (LLE) for the mixtures: phenylacetonitrile + heptane, + octane, + nonane, + cyclooctane, or + 2,2,4-trimethylpentane and for 3-phenylpropionitrile + heptane, or + octane are reported. Aromatic nitrile + alkane, + aromatic hydrocarbon or + 1 alkanol systems are investigated using a set of thermophysical properties: phase equilibria (solid-liquid, SLE, vapour-liquid, VLE and LLE), excess molar functions, enthalpies ($H_{\text{m}}^{\text{E}}$), isochoric internal energies, isobaric heat capacities ($C_{p \text{m}}^{\text{E}}$) and volumes ($V_{\text{m}}^{\text{E}}$), and the Kirkwood correlation factor. Due to proximity effects between the phenyl and the CN groups, dipolar interactions between molecules of aromatic nitriles are stronger than those between molecules of isomeric linear nitriles. Dipolar interactions become weaker in the order: 3-phenylpropionitrile > phenylacetonitrile > benzonitrile. Benzonitrile + aromatic hydrocarbon mixtures are characterized by dispersive interactions and structural effects. The latter are more important in systems with phenylacetonitrile. Structural effects are also present in benzonitrile + n-alkane, or + 1-alkanol + mixtures. The systems mentioned above have been studied using DISQUAC. Interaction parameters for contacts where the CN group in aromatic nitriles participates are given and DISQUAC results on excess properties and phase equilibria are discussed. 1-Alkanol + benzonitrile mixtures are also investigated by means of the ERAS model. ERAS represents well $H_{\text{m}}^{\text{E}}$ of these systems. The $V_{\text{m}}^{\text{E}}$ curves of solutions with longer 1-alkanols are more poorly described, which has been explained in terms of the existence of structural effects.

description: Structural features of newly found perovskite-based iron pnictide oxide system have been systematically studied. Compared to REFePnO system, perovskite-based system tend to have lower Pn-Fe-Pn angle and higher pnictogen height owing to low electronegativity of alkaline earth metal and small repulsive force between pnictogen and oxygen atoms. As-Fe-As angles of (Fe2As2)(Sr4Cr2O6), (Fe2As2)(Sr4V2O6) and (Fe2Pn2)(Sr4MgTiO6) are close to ideal tetrahedron and those pnictogen heights of about 1.40 A are close to NdFeAsO with optimized carrier concentration. These structural features of this system may leads to realization of high Tc superconductivity.

description: Abstract: The Kentucky Transportation Cabinet (KYTC) frequently acquires property to secure the right of way for transportation projects. Some property may eventually be declared excess and deemed surplus, enabling the Cabinet to dispose of it. Excess property can be declared surplus by an official order of the Secretary or Commissioner of the Department of Highways. Current law and policy require that KYTC undertake a 21-step process to dispose of surplus property, including reviews by the Governor, Finance and Administration Cabinet, and several KYTC personnel. The Cabinet lacks the personnel required to undertake the lengthy disposal process. This report provides background on KYTC’s surplus property disposal process, including definitions and processes with information drawn from the Right of Way Guidance Manual, and explores methods of surplus property disposal used in other states. It highlights which aspects of the disposal process other transportation agencies have outsourced to private consultants. Of the 14 states examined, several aggressively pursue the disposal of surplus property and employ consultants to assist with various facets of the process, including surveying, preparing land or legal descriptions, mapping and inventorying excess parcels, and selling property. The Appendix includes a sample Request for Proposals (RFP) template KYTC may considering using if it plans to re- train a consultant to assist in any or all aspects of the surplus property disposal.

description: Packing several characters into one computer word is a simple and natural way to compress the representation of a string and to speed up its processing. Exploiting this idea, we propose an index for a packed string, based on a {\em sparse suffix tree} \cite{KU-96} with appropriately defined suffix links. Assuming, under the standard unit-cost RAM model, that a word can store up to $\log_σn$ characters ($σ$ the alphabet size), our index takes $O(n/\log_σn)$ space, i.e. the same space as the packed string itself. The resulting pattern matching algorithm runs in time $O(m+r^2+r\cdot occ)$, where $m$ is the length of the pattern, $r$ is the actual number of characters stored in a word and $occ$ is the number of pattern occurrences.

description: Relative permittivities at 1 MHz, $\varepsilon_{\text{r}}$, and at (293.15-303.15) K are reported for the binary systems N,N-dimethylacetamide (DMA) + N-propylpropan-1-amine (DPA), + N-butylbutan-1-amine (DBA), + butan-1-amine (BA) or + hexan-1-amine (HxA) and for N,N-dimethylformamide (DMF) + aniline. The excess permittivities, $\varepsilon_{\text{r}}^{\text{E}}$, are large and negative for systems with DMA, whereas they are large and positive for the aniline mixture. From the analysis of these $\varepsilon_{\text{r}}^{\text{E}}$ data and of measurements previously reported, it is concluded: (i) the main contribution to $\varepsilon_{\text{r}}^{\text{E}}$ in systems with linear amines arises from the breaking of interactions between like molecules; (ii) in the DMF + aniline mixture, interactions between unlike molecules contribute positively to $\varepsilon_{\text{r}}^{\text{E}}$, and such a contribution is dominant; (iii) longer linear amines are better breakers of the amide-amide interactions; (iv) interactions between unlike molecules are more easily formed when shorter linear amines, or DMF, participate. These findings are confirmed by a general study conducted in terms of excess values of molar orientational and induced polarizabilities and of the relative Kirkwood correlation factors for systems and components. The ERAS model is also applied to amide + amine mixtures. ERAS represents rather accurately the excess enthalpies and volumes of the mentioned systems. The variation of the cross-association equilibrium constants, determined using ERAS, with the molecular structure is in agreement with that observed for $\varepsilon_{\text{r}}^{\text{E}}$.

Under-ice circulation in an Arctic lake : observations from two field seasons in Lake Kilpisjärvi, Finland
Creators: name: Graves, Kelly Elise
Publisher: name: University of British Columbia
Year: 2015

description: High spatial resolution CTD profiles and Acoustic Doppler Current Profiler velocity measurements show significant rotational basin-wide, under-ice circulation in May of 2013 and 2014 at Lake Kilpisjärvi, Finland (69°01'N, 20°49'E), a seasonally ice-covered, Arctic lake with negligible through-flow. In 2013, a high-pressure horizontal density anomaly with vertically paired rotating circulations was observed. The estimated maximum cyclonic and anti-cyclonic azimuthal velocities magnitudes were 0.03 and 0.02 m s-¹. The Rossby radius (Rri), horizontal length scale at which rotational effects become as important as pressure effects, was estimated to be ∼ 160 m and the Rossby number(R⃘⃘⃘⃘⃘ ), the ratio of the centripetal acceleration to the Coriolis acceleration, ∼ 0.2. It is hypothesized that this circulation was driven by heat flux at the shorelines from warm incoming streams causing a density flow down the slopes to the centre of the lake where the flow converged. This flow was balanced with a shoreward flow beneath the ice. These flows were modified by the earth's rotation, which resulted in the rotational circulation observed. In 2014, a cyclonic, low-pressure horizontal density anomaly was observed near the centre of the lake and was vertically paired with a weak anti-cyclonic anomaly in the top 10 m (mean depth of the lake is 19.5 m). The estimated azimuthal velocities had maximum cyclonic and anti-cyclonic magnitudes of 0.006 and 0.003 m s-¹. The anomaly was estimated to have Rri ∼ 240 m, with R⃘⃘ ∼ 0.12. It is hypothesized that this circulation was driven by sediment release of heat to the overlying water causing a tilt in the isopycnals near the shores of the lake that caused an inward pressure force that was balanced by the Coriolis force and, to a lesser extent, the centripetal acceleration force. The 2013 observations were made immediately prior to ice-off, and the 2014 observations were 12 days prior to ice-off. This time difference allowed for significantly different ice and snow conditions, and the addition of warm inflows, which forced the circulation closer to the ice-off date. These observations add to the growing understanding of the relationship between thermal distribution and circulation under ice.

description: This report represents an aspect of the ground truthing methods used to confirm the geomorphic mapping carried out as part of the Stability of Land In Dynamic Environments (SLIDE) project within the Wellington Region. A simple hammer plate seismic survey was completed in Camrose Grove, Kingston, Wellington, on an area of fill identified from historical records of US Marine Corps construction in Camrose Grove during WW2. The purpose of the survey is to confirm the geometry of the fill body and the depth to the historical ground surface calculated from the geomorphic mapping based on differencing of digital surface models derived from photogrammetry of historical air photos with modern LiDAR derived digital elevation data. Field survey of the site at the Camrose Grove sports field was carried out with a hammer and plate source and a StratavisorTMNX data recorder with 48 single-component geophones spaced at 4 m along a 175-m-long survey line crossing the deepest portion of the infilled valley. In addition to the pressure-wave vertical hammer and plate shots every 8 m, horizontal shear-wave shots on a weighted beam were also recorded at three sites to test the site for shear-wave velocity information. Data processing was carried out with Globe ClaritasTM processing software. The aim of the processing is to define seismic-wave velocities of both fill material and underlying greywacke to identify any variations within the fill and to determine the geometry of the base of the fill layer. Seismic refraction velocities were able to be modelled and the geometry of the refraction modelled greywacke contact agreed well with the modelled depths from the historical and LiDAR differenced ground model of the fill site, proving the usefulness of the differencing technique for geomorphic mapping. Seismic reflections were not observed in the field data. The poor quality of the reflection data is likely to be due to the sparse shot and receiver spacing used. The intense ground roll was spatially under-sampled preventing its removal from the reflection records. Similarly, as the survey was limited to single-axis geophones, together with the poor quality of the surface waves, this prevented spectral analysis of surface waves from being used to determine shear-wave velocities.

The Hausdorff-dimension of the set of directions is determined in terms of the $α$-value of Z in which visibility from a fixed point to the ideal boundary of the hyperbolic plane is possible within Z. Moreover, the Hausdorff-dimension of the set of (hyperbolic) lines through a fixed point contained in Z is calculated. Thereby several conjectures raised by Benjamini, Jonasson, Schramm and Tykesson are confirmed.

description: The location quotient (LQ) measures regional industry concentration with the advantages of easy calculation and interpretation. However, it is a weak method for identifying industry clusters that consist of related industries geographically concentrated in contiguous counties. This paper proposes a new spatial input–output location quotient (SI-LQ) accounting for both the co-location of related industries and the spatial spillover of concentration into neighbouring counties. A bootstrap method is used to determine the cut-off values of the new measure. The practical advantages of the SI-LQ over the traditional LQ include attenuation of the extreme values of the LQ in less populous and remote counties and the identification of large substantive clusters. The SI-LQ outperforms the LQ in a regression analysis of the effect of industry concentration on total employment growth.

description: Motivated by the recent proposal that one can obtain quasi-periodic oscillations (QPOs) by photon echoes manifesting as non-trivial features in the autocorrelation function (ACF), we study the ACFs of the light curves of three accreting black hole candidates and a neutron star already known to exhibit QPOs namely, GRS 1915+105, XTE J1550-564, XTE J1859+226 and Cygnus X-2. We compute and focus on the form of the ACFs in search of systematics or specific temporal properties at the time scales associated with the known QPO frequencies in comparison with the corresponding PDS. Even within our small object sample we find both similarities as well as significant and subtle differences in the form of the ACFs both amongst black holes and between black holes and neutron stars to warrant a closer look at the QPO phenomenon in the time domain: The QPO features manifest as an oscillatory behavior of the ACF at lags near zero; the oscillation damps exponentially on time scales equal to the inverse QPO width to a level of a percent or so. In black holes this oscillatory behavior is preserved and easily discerned at much longer lags while this is not the case for the neutron star system Cyg X-2. The ACF of GRS 1915+105 provides an exception to this general behavior in that its decay is linear in time indicating an undamped oscillation of coherent phase. We present simple ad hoc models that reproduce these diverse time domain behaviors and we speculate that their origin is the phase coherence of the underlying oscillation. It appears plausible that time domain analyses, complementary to the more common frequency domain ones, could impose tighter constraints and provide clues for the driving mechanisms behind the QPO phenomenon.

Frequency of peripheral neuropathy and injection site reactions in patients with multiple myeloma receiving subcutaneous versus intravenous bortezomib
Creators: name: Manchulenko, Cynthia

description: Multiple myeloma is an incurable hematological malignancy with patients living on average 3 to 6 years after diagnosis. Bortezomib is widely used to treat multiple myeloma. Peripheral neuropathy has been a major side effect associated with bortezomib treatment, and occurs in 47% to 64% of patients. Therefore, strategies to minimize this dose limiting toxicity have been studied and protocols have been revised accordingly. Bortezomib administered subcutaneously instead of intravenously is one strategy that has shown to decrease the incidence of peripheral neuropathy, is well-tolerated and equally as efficacious as bortezomib administered intravenously. Injection site reactions have been reported as mild. Furthermore, as far as the author is aware there is currently no published literature discussing the safety and tolerability of the back of the arm as an injection site for bortezomib. This was a retrospective, chart review of 53 subjects with multiple myeloma, conducted in two large academic medical centres in British Columbia. Incidence of peripheral neuropathy was collected and compared between those who had received bortezomib via intravenous and subcutaneous routes. Incidence of injection site reactions related to subcutaneous administration of bortezomib were also collected, and a comparison was done between the sites of injection (back of the arm, abdomen and thigh). Overall, peripheral neuropathy rates in this study were 28% (n=15/53). There was no statistically significant difference between frequencies of peripheral neuropathy for patients who received bortezomib via intravenous or subcutaneous routes (p = .490). There were a total of 861 injections, with 294 injections to the back of the arm, 487 injections to the abdomen, 130 injections to an unknown site and only one injection in the thigh. Of the 861 injections, there were eight (2%) Grade 1 injection reactions in the abdomen, and one Grade 3 injection reaction, in the thigh. None were reported in the back of the arm. In conclusion, a prospective study with a larger sample size is needed to examine if subcutaneously injected bortezomib results in less peripheral neuropathy than intravenously injected bortezomib. Furthermore, subcutaneously injected bortezomib is safe and well tolerated when injected in the back of the arm.

description: The symmetry breaking of 5-dimensional SU(6) GUT into 4-dimensional SU(3) x SU(3) x U(1) with orbifold S1/Z2 through Scherk-Schwarz mechanism is investigated. It is shown that the origin of Little Higgs can be generated to further break SU(3) x SU(3) x U(1) down to the electroweak scale through Higgs mechanism.

You know walls, can't contain me : approaches and reflections on directing Charles Mee's the Bacchae 2.1 as a hybrid theatre and the interfacing of Asian performance rituals to the Western spoken drama
Creators: name: Gupa, Dennis Desuyo
Publisher: name: University of British Columbia

description: My MFA Theatre Directing Thesis Production inquires on intercultural theatre through hybrid pollination of Asian ritual performances to the Western spoken theatre using Charles Mee's The Bacchae 2.1. What attracted me about this text is Mee's rendering of different cultural influences and layering of various artistic traditions into one dramatic expression. In one of the lines of Dionysus, he ascertained, "You know walls, can’t contain me…", the premise that signifies in this line is the process and approaches I employed in crafting this performance. Global issues influence my experiences as a contemporary artist, and my central interest in this project is to seek how cultures blend without a compromise. Mee's The Bacchae 2.1 captured this artistic rendition by sourcing various texts and materials while keeping the moral ethos and political premise of the original text. When cultures are mixed and blended to form a new style of artistic language, dialogues can then be opened between people of various cultural backgrounds. From this, new artistic forms are fused to transcend cultural differences in search of an understanding of the global human condition.

description: We synthesized new layered iron arsenide oxides (Fe2As2)(Sr4(Sc,Ti)3O8),(Fe2As2)(Ba4Sc3O7.5), and (Fe2As2)(Ba3Sc2O5). The crystal structures of these compounds are tetragonal with a space group of I4/mmm. The structure of (Fe2As2)(Sr4(Sc,Ti)3O8) and (Fe2As2)(Ba4Sc3O7.5) consists of the alternate stacking of antifluorite Fe2As2 layers and triple perovskite-type oxide layers. The interlayer distance between the Fe planes of (Fe2As2)(Ba4Sc3O7.5) is ~18.7 A. Moreover, the a-axis of (Fe2As2)(Ba3Sc2O5) is the longest among the layered iron pnictides, indicating the structural flexibility of the layered iron pnictide containing perovskite-type layers. The bulk sample of (Fe2As2)(Sr4(Sc0.6Ti0.4)3O8) exhibited diamagnetism up to 28 K in susceptibility measurements.

description: We investigate the physically allowed probabilities for transforming one N-partite W-class state to another by means of local operations assisted with classical communication (LOCC). Recently, Kintas and Turgut have obtained an upper bound for the maximum probability of transforming two such states [arXiv:1003.2118v1]. Here, we provide a simple sufficient and necessary condition for when this upper bound can be satisfied and thus when optimality of state transformation can be achieved. Our discussion involves obtaining lower bounds for the transformation of arbitrary W-class states and showing precisely when this bound saturates the bound of [arXiv:1003.2118v1]. Finally, we consider the question of transforming symmetric W-class states and find that in general, the optimal one-shot procedure for converting two symmetric states requires a non-symmetric filter by all the parties.

description: The liquid-liquid equilibrium (LLE) curves have been determined for the 2-hydroxyl-benzaldehyde (salicylaldehyde, SAC) + CH$_3$(CH$_2$)$_n$CH$_3$ mixtures ($n$ = 5,6,7,8,9). The equilibrium temperatures were determined observing, by means of a laser scattering technique, the turbidity produced on cooling when a second phase takes place. All the systems show an upper critical solution temperature, which linearly increases with $n$. Intermolecular effects have been investigated in alkanol + benzaldehyde systems using data from the literature. Interactions in 1-alkanol mixtures are mainly of dipolar type. The corresponding excess molar enthalpies, $H_{\text{m}}^{\text{E}}$, are large and positive, which reveals that interactions between like molecules are dominant. Interactions between unlike molecules are stronger for the methanol-containing system. For the other mixtures, the enthalpy of the (1-alkanol)-benzaldehyde interactions remains more or less constant. At 298.15 K and equimolar composition, the replacement of a linear polar solvent by the isomeric aromatic one leads to increased $H_{\text{m}}^{\text{E}}$ values in systems with a given 1-alkanol. The phenol + benzaldehyde system shows strongly negative deviations from the Raoult's law. Proximity effects have been examined in SAC + hydrocarbon mixtures. Alkane-containing systems are essentially characterized by dipolar interactions, while dispersive interactions are prevalent in the solution with benzene. All the mixtures have been treated in terms of DISQUAC. The interaction parameters for the OH/CHO contacts and for the SAC/aromatic and SAC/alkane contacts have been reported. DISQUAC provides a correct description of the thermodynamic properties considered. In the case of SAC systems, this is done by defining a new specific group HO-C-C-CHO for salicylaldehyde.
SuperParticle realization of twisted N=2 SUSY algebra

description: We construct a pseudoclassical particle model associated to the twisted N=2 SUSY algebra in four dimensions. The particle model has four kappa symmetries. Three of them can be used to reduce the model to the vector supersymmetry particle case. The quantization of the model gives rise to two copies of the 4d Dirac equation. The kappa symmetries result to be associated to 4 TSUSY invariant bilinear odd operators who are null operators when a particular condition is satisfied. These operators are in correspondence one to one with analogous operators existing in the case of the N=2 SUSY algebra, making both cases 1/2 BPS.
