description: We analyze the ground state phases of two-component ($σ\equiv \lbrace \uparrow, \downarrow \rbrace$) population- and mass-balanced ($N_\uparrow = N_\downarrow$ and $m_\uparrow = m_\downarrow$) but trap-imbalanced ($ω_\uparrow \ne ω_\downarrow$) fermion mixtures as a function of interaction strength from the weak attraction Bardeen-Cooper-Schrieffer (BCS) to the strong attraction Bose-Einstein condensation (BEC) limit. In the BCS limit, we find that the unpolarized superfluid (UPS) fermions exist away from the central core of the trapping potentials, and are surrounded by partially polarized normal (P$σ$PN) fermions. As the interactions increase towards unitarity, we find that the central P$σ$PN core first transitions to a UPS, and then expands towards the edges until the entire mixture becomes a UPS in the BEC limit.

description: The evolution of Supermassive Black Holes (SMBHs) initially embedded in the centres of merging galaxies realised with a stellar mass function (SMF) is studied from the onset of galaxy mergers till coalescence. We performed a large set of direct N-body simulations with three different slopes of the central stellar cusp and different random seeds. Post Newtonian terms up to order 3.5 are used to drive the SMBH binary evolution in the relativistic regime. The impact of a SMF on the hardening rate and the coalescence time is investigated. We find that SMBH binaries coalesce well within one billion years when our models are scaled to galaxies with a steep cusp at low redshift. Here higher central densities provide larger supply of stars to efficiently extract energy from the SMBH binary orbit and shrink it to the phase where gravitational wave (GW) emission becomes dominant leading to the coalescence of the SMBHs. Mergers of models with shallow cusps that are representative for giant elliptical galaxies having central cores result in less efficient extraction of binary orbital energy due to the lower stellar densities in the centre. However, high values of eccentricity witnessed for SMBH binaries in such galaxy mergers ensure that the GW emission dominated phase sets in earlier at larger values of the semi-major axis. This helps to compensate for the less efficient energy extraction during the phase dominated by stellar encounters resulting in mergers of SMBHs in about one Gyr after the formation of the binary. Additionally, we witness mass segregation in the merger remnant resulting in enhanced SMBH binary hardening rates. We show that at least the final phase of the merger in cuspy low mass galaxies would be observable with the GW detector eLISA.

description: Rydberg atoms immersed in a Bose-Einstein condensate interact with the quantum gas via electron-atom and ion-atom interaction. To suppress the typically dominant electron-neutral interaction, Rydberg states with principal quantum number up to $n = 190$ are excited from a dense and tightly trapped micron-sized condensate. This allows us to explore a regime where the Rydberg orbit exceeds the size of the atomic sample by far. In this case, a detailed lineshape analysis of the Rydberg excitation spectrum provides clear evidence for ion-atom interaction at temperatures well below a microkelvin. Our results may open up ways to enter the quantum regime of ion-atom scattering for the exploration of charged quantum impurities and associated polaron physics.

description: We develop an analytical diffusion-equation-type approximation scheme for the one-dimensional coagulation reaction A+A->A with partial reaction probability on particle encounters which are otherwise hard-core. The new approximation describes the crossover from the mean-field rate-equation behavior at short times to the universal, fluctuation-dominated behavior at large times. The approximation becomes quantitatively accurate when the system is initially close to the continuum behavior, i.e., for small initial density and fast reaction. For large initial density and slow reaction, lattice effects are nonnegligible for an extended initial time interval. In such cases our approximation provides the correct description of the initial mean-field as well as the asymptotic large-time, fluctuation-dominated behavior. However, the intermediate-time crossover between the two regimes is described only semiquantitatively.

description: Istat calculates the concern about climate change in the Italian regions. The variable is defined as the percentage of electricity consumption covered by renewable sources out of total gross internal consumption. The indicator is obtained as the ratio between the actual gross electricity production from RES (not normalised) and the Gross Domestic Consumption of electricity (equal to the gross production of electricity gross of production from pumping contributions plus the balance of exchanges with the abroad or between regions). The data refers to the Italian regions between 2012 and 2022.

description: Holes confined in quantum dots have gained considerable interest in the past few years due to their potential as spin qubits. Here we demonstrate double quantum dot devices in Ge hut wires. Low temperature transport measurements reveal Pauli spin blockade. We demonstrate electric-dipole spin resonance by applying a radio frequency electric field to one of the electrodes defining the double quantum dot. Next, we induce coherent hole spin oscillations by varying the duration of the microwave burst. Rabi oscillations with frequencies reaching 140MHz are observed. Finally, Ramsey experiments reveal dephasing times of 130ns. The reported results emphasize the potential of Ge as a platform for fast and scalable hole spin qubit devices.
An Analysis of the Decay $B \rightarrow D^* X \ell \barν_\ell$ with Predictions from Heavy Quark and Chiral Symmetry

description: This paper considers the implications of the heavy quark and chiral symmetries for the semi-leptonic decay $B \rightarrow D^* X \ell \bar ν_\ell$. The general kinematic analysis for decays of the form {\sl pseudoscalar meson $\rightarrow$ vector meson $+$ pseudoscalar meson $+$ lepton $+$ anti-lepton} is presented. This formalism is applied to the above exclusive decay which allows the differential decay rate to be expressed in a form that is ideally suited for the experimental determination of the different form factors for the process through angular distribution measurements. Heavy quark and chiral symmetry predictions for the form factors are presented, and the differential decay rate is calculated in the kinematic region where chiral perturbation theory is valid.

description: Objective: This study aimed to determine whether anti-rK39 antibodies were diagnostic markers forvisceral leishmaniasis (kala-azar) and to evaluate the correlation between age and gender in disease occurrencein Iraqi patients. In addition, it aimed to evaluate the correlation between thyroid hormones,i.e., thyroid-stimulating hormone (TSH), triiodothyronine (T3), and thyroxine (T4) and anti-rK39 antibodies.Materials and Methods: Immunochromatographic technique used for anti-rK39 antibodies detection.Enzyme-linked immunosorbent assay was used for determining the serum TSH, T3, and T4 levels.Results: One hundred thirty-eight patients with visceral leishmaniasis were included. The mean age was27.65±11.60 years. Sixty-one patients (44.2%) were males, and their mean age was 29.65±11.10 years.The mean age of females was 26.12±11.89 years. Anti-rK39 antibodies were detected in 11.59% ofpatients. Anti-rK39 antibodies were equally detected (5.8%) in both genders without a significant difference(p=0.212) or correlation between gender and anti-rK39 antibodies (p=0.623). There was neithera significant difference (p>0.05) nor correlation between gender; age groups according to gender andanti-rK39 antibodies (p>0.05). Both males and females who were positive for anti-rK39 antibodieshad normal TSH, T3, and T4 levels. Only one patient who was positive for anti-rK39 antibodies hadan elevated T4 level (>12 μg/dL). Neither a significant difference nor correlation was reported amonggenders; anti-rK39 antibody positivity (p>0.05); and TSH, T3, and T4 levels.Conclusion: Anti-rK39 antibodies, a daignostic marker for visceral leishmaniasis have no correlationwith patients age and gender. Serum TSH and T3 levels were not affected by visceral leishmaniasis.Visceral leishmaniasis causes the increase in serum T4 levels. Thyroid involvement appears to be uncommonin patients who present with visceral leishmaniasis.

description: We generalize the evolution model introduced by Guiol, Machado and Schinazi (2010). In our model at odd times a random number X of species is created. Each species is endowed with a random fitness with arbitrary distribution on $[0, 1]$. At even times a random number Y of species is removed, killing the species with lower fitness. We show that there is a critical fitness $f_c$ below which the number of species hits zero i.o. and above of which this number goes to infinity. We prove uniform convergence for the distribution of surviving species and describe the phenomena which could not be observed in previous works with uniformly distributed fitness.

Entangled Histories
Police Ordinances

description: Entangled History! Making Ordinances Searchable. To open up early modern legal historical sources (ordinances), the Entangled History project will run from May-October 2019. Its aim is to systematically categorise the normative texts (according to MPIeR-standards). It will be the starting point to identify influencers throughout the Low Countries and maybe – in due time – even outside of that. It will, too, show what may be the true nature – identity – of a province. This presentation/ poster will describe this Digital Humanities-Project and ask participants to think along and come with suggestions for the project – and future DH-projects. It involves the (1) improvement of the currently applied OCR-technique to a much higher recognition-standard with HTR. It (2) enhances readability by systematically segmenting individual texts, recognising text-sections – beginning or end, columns, titles, dates, summaries, the body of the text. In order to improve the searchability, I suggest the (3) application of a standard categorisation (metadata) with a machine-learned algorithm. A categorisation by a machine-learned algorithm will offer ample possibilities to computer-search for similar topics within texts and do content-based longitudinal searches, whereas the actual title may not be so helpful to modern readers. The KB-library hosts at least 42 digitised plakkaatboeken (bundles of normative texts – ca.1540s-1800s) and near 5000 individual plakkaten (16th-19th century). These texts contain indications of how governments of burgeoning states dealt with unexpected threats to safety, security, and order through home-invented measures, borrowed rules, or adjustments of what was established elsewhere.
Bell measurement rules out supraquantum correlations

description: The so called bipartite non-signaling boxes are systems whose statistics is constrained solely by the principle of no instantaneous signaling between distant locations. Such systems can exhibit much stronger correlations than those admitted by quantum mechanics. Inspired by quantum logic approach of Tylec and Kuś, J. Phys. A: Math. Theor. 48 (2015) 505303, we consider non-signaling boxes with three inputs per party, and extend the set of measurements with just a single {\it global} measurement - one that mimics quantum two-party Bell measurement. We then show that this seemingly mild extension completely rules out supraquantum correlations: the resulting system admits precisely quantum mechanical correlations of two qubits. We also consider non-maximally entangled measurements, obtaining interpolation between quantum and full no-signaling theory. Our study paves a way to a general programme of amending no-signaling theories with some measurements inherited from quantum mechanics, leading to various interpolations between non-signaling boxes and quantum mechanics.

description: We present results on the equation of state in QCD with two light quark flavors and a heavier strange quark. Calculations with improved staggered fermions have been performed on lattices with temporal extent Nt =4 and 6 on a line of constant physics with almost physical quark mass values; the pion mass is about 220 MeV, and the strange quark mass is adjusted to its physical value. High statistics results on large lattices are obtained for bulk thermodynamic observables, i.e. pressure, energy and entropy density, at vanishing quark chemical potential for a wide range of temperatures, 140 MeV < T < 800 MeV. We present a detailed discussion of finite cut-off effects which become particularly significant for temperatures larger than about twice the transition temperature. At these high temperatures we also performed calculations of the trace anomaly on lattices with temporal extent Nt=8. Furthermore, we have performed an extensive analysis of zero temperature observables including the light and strange quark condensates and the static quark potential at zero temperature. These are used to set the temperature scale for thermodynamic observables and to calculate renormalized observables that are sensitive to deconfinement and chiral symmetry restoration and become order parameters in the infinite and zero quark mass limits, respectively.

description: We study the ground state properties of the bond alternating $S=1/2$ quantum spin chain whose Hamiltonian is H=\sum_j (S_{2j}^x S_{2j+1}^x +S_{2j}^y S_{2j+1}^y +λS_{2j}^z S_{2j+1}^z ) +β\sum_j {\bf S}_{2j-1} \cdot {\bf S}_{2j} . When $β=0$, the ground state is a collection of local singlets with a finite excitation gap. In the limit of strong ferromagnetic coupling $β\to - \infty$, this is equivalent to the $S=1 \ XXZ$ Hamiltonian. It has several ground state phases in the $λ$-$β$ plane including the gapful Haldane phase. They are characterized by a full breakdown, partial breakdowns and a non-breakdown of the hidden discrete $Z_2 \times Z_2$ symmetry. The ground state phase diagram is obtained by series expansions.

description: We report the discovery with XMM-Newton of 3-s X-ray pulsations from 3XMM J004232.1+411314, a dipping source that dominates the hard X-ray emission of M31. This finding unambiguously assesses the neutron star (NS) nature of the compact object. We also measured an orbital modulation of 4.15 h and a projected semi-axis at $a_{\mathrm{X}} \sin i= 0.6$ lt-s, which implies a low-mass companion of about 0.2$-$0.3$M_{\odot}$ assuming a NS of 1.5 $M_{\odot}$ and an orbital inclination $i=70^{\circ}-80^{\circ}$. The barycentric orbit-corrected pulse period decreased by $\sim$28 ms in about 16 yr, corresponding to an average spin-up rate of $\dot{P} \sim -6 \times 10^{-11}$ s s$^{-1}$ ; pulse period variations, probably caused to by X-ray luminosity changes, were observed on shorter time scales. We identify two possible scenarios for the source: a mildly magnetic NS with $B_{\mathrm{p}}\simeq$ few $\times10^{10}$ G if the pulsar is far from its equilibrium period $P_{\mathrm{eq}}$, and a relatively young highly magnetic NS with $B_{\mathrm{eq}}\simeq 10^{13}$ G if spinning close to $P_{\mathrm{eq}}$.

description: We study pair production from a strong electric field in boost-invariant coordinates as a simple model for the central rapidity region of a heavy-ion collision. We derive and solve the renormalized equations for the time evolution of the mean electric field and current of the produced particles, when the field is taken to be a function only of the fluid proper time $τ= \sqrt{t^2-z^2}$. We find that a relativistic transport theory with a Schwinger source term modified to take Pauli blocking (or Bose enhancement) into account gives a good description of the numerical solution to the field equations. We also compute the renormalized energy-momentum tensor of the produced particles and compare the effective pressure, energy and entropy density to that expected from hydrodynamic models of energy and momentum flow of the plasma.

description: Virtual Observatories (VOs) are online hubs of scientific knowledge. They encompass a collection of platforms dedicated to the storage and dissemination of astronomical data, from simple data archives to e-research platforms offering advanced tools for data exploration and analysis. Whilst the more mature platforms within VOs primarily serve the observational community, there are also services fulfilling a similar role for theoretical data. Scientific visualization can be an effective tool for analysis and exploration of datasets made accessible through web platforms for theoretical data, which often contain spatial dimensions and properties inherently suitable for visualization via e.g. mock imaging in 2d or volume rendering in 3d. We analyze the current state of 3d visualization for big theoretical astronomical datasets through scientific web portals and virtual observatory services. We discuss some of the challenges for interactive 3d visualization and how it can augment the workflow of users in a virtual observatory context. Finally we showcase a lightweight client-server visualization tool for particle-based datasets allowing quantitative visualization via data filtering, highlighting two example use cases within the Theoretical Astrophysical Observatory.

On examining certain alliances, particularly her co-authorship as illustrator of the first edition of Luís Bernando Honwana's Nós Matámos o Cão-Tinhoso (We Killed the Mangy Dog), 1964, I consider and seek to redress Lopes's tacit experience of colonial racism, which arguably drove her unflinching anti-colonial militancy with a brush. In this, I posit that Lopes be considered a founding figure in a women's genealogy of African modernist achievement.

description: Type Ic supernovae (SNe) can be classified as: normal SNe Ic, type Ic super-luminous SNe (SLSNe Ic), X-ray flash (XRF) connected SNe, broad-line SNe Ic (SN Ic-BL), and gamma-ray burst (GRB) connected SNe. Here we suggest an inner connection for all kinds of SNe Ic based on a pair of jets being successfully launched: a normal SN Ic is a normal core collapsar without jets launched; a GRB associated SN Ic is a core collapsar with relativistic jets launched and successfully breaking out the envelope of the progenitor; an XRF associated SN Ic is a core collapsar with jets launched but can only develop a relativistic shock breakout; an SN Ic-BL is an off-axis GRB or XRF associated supernova; and an SLSN Ic is close to the XRF-SN Ic but the shock breakout is not relativistic and most of the jet energy is deposited into the supernova component. Based on the luminosity-distance diagram, we derived the luminosity function of all different types of SNe Ic as a whole. We also show that the normal SNe Ic and GRB connected SNe Ic have similar accumulative distributions.

description: We propose a range-separated hybrid exchange-correlation functional to calculate solid-state material properties. The functional mixes Hartree-Fock exchange with the semilocal exchange of the meta-generalized gradient approximation (meta-GGA) and the fraction of Hartree-Fock exchange is determined from the dielectric function. First-principles calculations and comparison with other meta-GGA approximations show that the functional leads to reasonably good performance for the band gap and optical properties. We also show that the present functional also successfully resolves the well-known ``band gap problem'' of narrow gap Cu-based semiconductors, such as Cu3SbSe4 and Cu3AsSe4, where, in general, a considerably large band inversion energy leads to a ``false'' negative or metallic band gap for all other methods. Furthermore, reasonable accuracy for the occupied d-bands and transition energies is also obtained for bulk solids. Thus, overall, our results demonstrate the predictive power of range-separated meta-GGA hybrid functionals for quantum materials simulations.

description: We determine the characteristic length scale, $L(t)$, in phase ordering kinetics for both scalar and vector fields, with either short- or long-range interactions, and with or without conservation laws. We obtain $L(t)$ consistently by comparing the global rate of energy change to the energy dissipation from the local evolution of the order parameter. We derive growth laws for O(n) models, and our results can be applied to other systems with similar defect structures.

description: The article shows that there are extensively overlapping brain responses between a speaker and a listener, as well as within and across speakers, in a face-to-face conversation using functional MRI and a time-warping method. This study addresses the challenge of mapping the spatial overlap between speech production and perception systems through the retelling method. In this article evaluation, four main aspects — content, methodology, language, and format — will be discussed, along with the evaluation against the provided background material (Uri Hasson’s videos on brain-to-brain coupling) and other materials present in the course. Other observations and conclusions will be mentioned towards the end.

description: An analytical approximation to periodic orbits in the circular restricted three-body problem is provided. The formulation given in this work is based in calculations known from classical mechanics, but with the addition of the necessary terms to give a fairly good approximation that we compare with simulations, resulting in a simple set of analytical expressions that solve periodic orbits on discs of binary systems without the need of solving the motion equations by numerical integrations.

description: We reduce measurement errors in a quantum computer using machine learning techniques. We exploit a simple yet versatile neural network to classify multi-qubit quantum states, which is trained using experimental data. This flexible approach allows the incorporation of any number of features of the data with minimal modifications to the underlying network architecture. We experimentally illustrate this approach in the readout of trapped-ion qubits using additional spatial and temporal features in the data. Using this neural network classifier, we efficiently treat qubit readout crosstalk, resulting in a 30\% improvement in detection error over the conventional threshold method. Our approach does not depend on the specific details of the system and can be readily generalized to other quantum computing platforms.

Entangled Histories

description: The Low Countries’ Plakkaatboeken: Entangled Histories between ±1500-1800?! Text-segmentation and machine-learned meta-dating. In the early modern era (± 1500-1800) Europe consisted of a patchwork of small states. The underlying hypothesis of this Entangled Histories-project is that those in government did not invent the wheel each and every single time a problem arose and were prone to copy parts of successful legislation from neighbouring states. Nowadays, European libraries and archives hold plakkaatboeken (books of ordinances): compilations of legislative texts issued from the 15th until the 18th century. These contain information on how governments of burgeoning states dealt a wide range of topics: from religion to waterworks, from marriage to economics. The hundreds of texts within these compilations are frequently consulted by researchers of various disciplines (e.g. law, history, political science, linguists) to understand how complex societies were controlled. Within Entangled Histories, nearly all digitally available books of ordinances of the Low Countries are used. (1) Entangled Histories commences with an improvement of the OCR through HTR-methods (Handwriting Text-Recognition) to obtain a higher quality of recognition (CER<5%). After training the (2) page mark-up (3) machine-generated metadata is created after supervised training based on a Naive Bayes classifier. This is a pilot that will prove the applicability of the tool to other languages as well, due to the presence of multiple languages. This project will disclose the entangled histories of neighbouring states, due to synchronic and diachronic comparisons – allowing a wider search and implementation in other multidisciplinary projects within Europe.

description: O tais (ikat) timorense emerge de uma prática têxtil ancestral, exclusivamente feminina, que passa oralmente e por demonstração de mãe para filha, neta ou nora, firmando-se em experiências colectivas e individuais. Se a complexidade tecnológica e a diversidade estilística regional têm sido analisadas de modo aprofundado no contexto da reconstrução de Timor-Leste, ainda que de forma escassa e circunscrita, as políticas da memória inscritas no e veiculadas pelo têxtil na sua relação com a arte contemporânea e a curadoria são praticamente inexistentes. Como objecto de herança cultural intrínseco à história do território, e como objecto artístico, sagrado e quotidiano sujeito a diversas transformações, o tais conta muitas histórias: as pré-coloniais, as coloniais e as neocoloniais. Conta ainda histórias no feminino, materializando-se, nesse sentido, como um objecto do passado, presente e futuro. Como e quando foram essas histórias alteradas e sobrepostas? Que imaginários são colocados em prática? E de que forma podem resgatar um passado e relacioná-lo com o futuro? Neste artigo foco-me em duas perspectivas curatoriais que tratam de maneira distinta o tais como matéria referencial: a exposição histórica, Textiles of Timor, Island in the Woven Sea (2014-15) e a exposição contemporânea, Elastic/Borracha/Elástico (2014). Através do conceito memórias praticadas conduzidas pelo próprio tais, na primeira exposição, exponho camadas dos tempos colonial e neocolonial que dão continuidade à temática da exposição, destacando aspectos ambivalentes da memória colectiva timorense; na segunda exposição, incido em práticas contemporâneas que recentram o poder imagético e ancestral do tais, reforçando a sua contemporaneidade. Destas análises, resultam questões incontornáveis para um debate actualizado em torno das memórias dos sujeitos e objectos colonizados.

description: We develop a new approach to the theoretical treatment of the separatrix chaos, using a special analysis of the separatrix map. The approach allows us to describe boundaries of the separatrix chaotic layer in the Poincaré section and transport within the layer. We show that the maximum which the width of the layer in energy takes as the perturbation frequency varies is much larger than the perturbation amplitude, in contrast to predictions by earlier theories suggesting that the maximum width is of the order of the amplitude. The approach has also allowed us to develop the self-consistent theory of the earlier discovered (PRL 90, 174101 (2003)) drastic facilitation of the onset of global chaos between adjacent separatrices. Simulations agree with the theory.

description: The separate spin evolution (SSE) of electrons causes the existence of the spin-electron acoustic wave. Extraordinary spin-electron acoustic waves (SEAWs) propagating perpendicular to the external magnetic field have large contribution of the transverse electric field. Its spectrum has been studied in the quasi-classical limit at the consideration of the separate spin evolution. The spin-spin interaction and the quantum Bohm potential give contribution in the spectrum extraordinary SEAW. This contribution is studied in this paper. Moreover, it is demonstrated that the spin-spin interaction leads to the existence of the extraordinary SEAWs if the SSE is neglected. The hybridization of the extraordinary SEAW and the lower extraordinary wave in the regime, where the cyclotron frequency is larger then the Langmuir frequency is studied either.

description: Coxiella burnetii is an intracellular bacterial pathogen which causes Q fever, a human infection with the ability to cause chronic disease with potentially life-threatening outcomes. In humans, Coxiella infects alveolar macrophages where it replicates to high numbers in a unique, pathogen-directed lysosome-derived vacuole. This compartment, termed the Coxiella-containing vacuole (CCV), has a low internal pH and contains markers both of lysosomes and autophagosomes. The CCV membrane is also enriched with CLTC (clathrin heavy chain) and this contributes to the success of the CCV. Here, we describe a role for CLTC, a scaffolding protein of clathrin-coated vesicles, in facilitating the fusion of autophagosomes with the CCV. During gene silencing of CLTC, CCVs are unable to fuse with each other, a phenotype also seen when silencing genes involved in macroautophagy/autophagy. MAP1LC3B/LC3B, which is normally observed inside the CCV, is excluded from CCVs in the absence of CLTC. Additionally, this study demonstrates that autophagosome fusion contributes to CCV size as cell starvation and subsequent autophagy induction leads to further CCV expansion. This is CLTC dependent, as the absence of CLTC renders autophagosomes no longer able to contribute to the expansion of the CCV. This investigation provides a functional link between CLTC and autophagy in the context of Coxiella infection and highlights the CCV as an important tool to explore the interactions between these vesicular trafficking pathways.

IDEF0 standard

description: A set of regulatory and technical documents regulate the design and operation of thermal power plants (TPPs) in the Russian Federation. It is important to coordinate legal, environmental, and other TPP indicators with specialists of various profiles during the initial design stage, as well as establish a general concept and structure for the station. There are no documents regulating this procedure in the Russian Federation's conventional professional criteria. A methodology and a family of IDEF standards covering all stages and aspects of design were developed and adopted as national standards in a number of countries, including individual products in Russia, at the end of the twentieth and beginning of the twenty-first centuries. The IDEF technique is written in a visual graphical language that can be used for interprofessional communication. The implementation of the IDEF0 specification at the initial design stage of thermal power plants is discussed in this paper. IDEF standards should complement technical standards. These will speed up the design process and increase the efficiency of TPP operation.

description: Effects on C60 by thermal fluctuations of phonons, misalignment of molecules in a crystal, and other intercalated impurities are simulated by disorder potentials. The SSH model for doped C60 is solved with gaussian bond and site disorders. Polarons and dimerizations in lightly doped cases (C60^{-1,-2}) are relatively stable against disorders, indicated by peak structures in distribution functions of bond length and charge density.
