description: Hydrogenic excited states of a 2D exciton are degenerate. In the presence of a weak magnetic field, the $S$-states with a zero momentum of the center of mass get coupled to the $P$-states with finite momentum of the center of mass. This field-induced coupling leads to a strong modification of the dispersion branches of the exciton spectrum. Namely, the lower branch acquires a shape of a "mexican hat" with a minimum at a finite momentum. At certain magnetic field, exciton branches exhibit a linear crossing, similarly to the spectrum of a 2D electron in the presence of spin-orbit coupling. While spin is not involved, degenerate $S$ and $P$ states play the role of the spin projections. Lifting of degeneracy due to diamagnetic shifts and deviation of electron-hole attraction from purely Coulomb suppresses the linear crossing.

description: The present article reports experimental observation and analyses of a supercritical bifurcation of combustion instabilities triggered by the air inlet temperature (Ta). The studies are performed with a pressurised kerosene fuelled Lean Premixed Prevaporized (LPP) combustor operated under elevated temperature. Unlike some previous studies, starting from an unstable condition of the system, the amplitude of combustion instabilities suddenly decrease when Ta exceeds a critical value of Ta =570 K. When the temperature is lowered back the system returns to being unstable without featuring any hysteresis behaviour, as expected in case of a supercritical bifurcation. The unstable flames feature a periodic axial motion of lift-off and re-ignition, characterized as Helmholtz mode. The phase difference between chemiluminescence and pressure signals is found to increase with Ta, exceeding 90 degrees (out of phase) for temperatures higher than 570 K. A low order network framework is conducted, illustrating that when Ta is increased a stability shift of this mode is predicted at Ta near 570 K, in good agreement with the experimental observations. The impact of Ta on the spray characteristics is also examined, finding that higher Ta promotes fuel evaporation and reduces equivalence ratio fluctuation at the exit of the swirler.

description: In light of the fact that climate change has emerged as one of the difficulties confronting the global food system, researchers are obligated to work toward developing fundamental crops, particularly wheat, to combat environmental stress, including drought and salt. In the present study, genetic engineering was used to transfer the Arabidopsis MDAR1 gene, which controls the buildup of ascorbic acid (AsA) to make bread wheat less likely to be sensitive to salt stress. The biolistic bombardment was used to transfer cDNA from the Arabidopsis thaliana plant that encodes MDAR1 into Bobwhite 56 cultivar wheat plants. A molecular investigation was performed on six different transgenic lines to confirm the integration of the transgene, the copy number, and the expression of the transgene. There were one to three copies of the transgene, and there was no association found between the number of copies of the transgene and All the data generated or analyzed during this study are included in this published article [and its supplementary information files].the presence of its expression. Compared to plants that were not transgenic, the amount of ascorbic acid (AsA) that accumulated in the transgenic plants was twice as high. ROS concentrations are significantly lower in transgenic plants compared to non-transgenic plants under both control and salt stress conditions, effectively reducing oxidative stress. By cultivating transgenic T2 plants in a greenhouse, we were able to determine whether they were able to tolerate the potentially damaging effects of salt stress (200 mm). The study concluded that transgenic wheat plants that consistently expressed the MDAR1 gene become tolerant to salt stress with improvement in growth characteristics.
PreMevE Update: Forecasting Ultra-relativistic Electrons inside Earth's Outer Radiation Belt

description: Energetic electrons inside Earth's outer Van Allen belt pose a major radiation threat to space-borne electronics that often play vital roles in our modern society. Ultra-relativistic electrons with energies greater than or equal to two Megaelectron-volt (MeV) are of particular interest due to their high penetrating ability, and thus forecasting these >=2 MeV electron levels has significant meaning to all space sectors. Here we update the latest development of the predictive model for MeV electrons inside the Earth's outer radiation belt. The new version, called PreMevE-2E, focuses on forecasting ultra-relativistic electron flux distributions across the outer radiation belt, with no need of in-situ measurements except for at the geosynchronous (GEO) orbit. Model inputs include precipitating electrons observed in low-Earth-orbits by NOAA satellites, upstream solar wind conditions (speeds and densities) from solar wind monitors, as well as ultra-relativistic electrons measured by one Los Alamos GEO satellite. We evaluated a total of 32 supervised machine learning models that fall into four different classes of linear and neural network architectures, and also successfully tested ensemble forecasting by using groups of top-performing models. All models are individually trained, validated, and tested by in-situ electron data from NASA's Van Allen Probes mission. It is shown that the final ensemble model generally outperforms individual models overs L-shells, and this PreMevE-2E model provides reliable and high-fidelity 25-hr (~1-day) and 50-hr (~2-day) forecasts with high mean performance efficiency values. Our results also suggest this new model is dominated by non-linear components at low L-shells (< ~4) for ultra-relativistic electrons, which is different from the dominance of linear components at all L-shells for 1 MeV electrons as previously discovered.

The Epic Story of Maximum Likelihood
Creators: name: Stigler, Stephen M.
Publisher: name: arXiv
Year: 2008
Subjects: subject: Methodology (stat.ME)
subject: FOS: Computer and information sciences

description: At a superficial level, the idea of maximum likelihood must be prehistoric: early hunters and gatherers may not have used the words ``method of maximum likelihood'' to describe their choice of where and how to hunt and gather, but it is hard to believe they would have been surprised if their method had been described in those terms. It seems a simple, even unassailable idea: Who would rise to argue in favor of a method of minimum likelihood, or even mediocre likelihood? And yet the mathematical history of the topic shows this ``simple idea'' is really anything but simple. Joseph Louis Lagrange, Daniel Bernoulli, Leonard Euler, Pierre Simon Laplace and Carl Friedrich Gauss are only some of those who explored the topic, not always in ways we would sanction today. In this article, that history is reviewed from back well before Fisher to the time of Lucien Le Cam's dissertation. In the process Fisher's unpublished 1930 characterization of conditions for the consistency and efficiency of maximum likelihood estimates is presented, and the mathematical basis of his three proofs discussed. In particular, Fisher's derivation of the information inequality is seen to be derived from his work on the analysis of variance, and his later approach via estimating functions was derived from Euler's Relation for homogeneous functions. The reaction to Fisher's work is reviewed, and some lessons drawn.

description: Using a combination of ground state quantum Monte-Carlo and finite size scaling techniques, we perform a systematic study of the effect of Coulomb interaction on the localisation length of a disordered two-dimensional electron gas. We find that correlations delocalise the 2D system. In the absence of valley degeneracy (as in GaAs heterostructures), this delocalization effect corresponds to a finite increase of the localization length. The delocalisation is much more dramatic in the presence of valley degeneracy (as in Si MOSFETSs) where the localization length increases drastically. Our results suggest that a rather simple mechanism can account for the main features of the metallic behaviour observed in high mobility Si MOSFETs. Our findings support the claim that this behaviour is indeed a genuine effect of the presence of electron-electron interactions, yet that the system is not a ``true'' metal in the thermodynamic sense.

description: We investigate quantum phase transitions in the extended periodic Anderson model, which includes electron correlations within and between itinerant and localized bands. We calculate zero and finite temperature properties of the system using the combination of dynamical mean-field theory and the numerical renormalization group. At half filling, a phase transition between a Mott insulating state and a Kondo insulating state occurs in the strong coupling regime. We furthermore find that a metallic state is stabilized in the weak coupling regime. This state should be adiabatically connected to the orbital selective Mott state with one orbital localized and the other itinerant. The effect of hole doping is also addressed.

title: Women and home in cinema: film practice and gendered spaces
Creators: name: Radinger Field, Louise
Publisher: name: University of Reading
Year: 2023

description: This thesis investigates how domestic space is represented in ten films released between 1936 and 2013 in which the woman in the home is placed at the heart of the drama. It examines how material structures are reconfigured into onscreen spaces which are full of expressivity and imbued with meaning. To understand how filmmakers achieve these spatial transformations, the thesis focuses on four material processes: découpage, mise-en-scène, sound and editing. Each chapter covers one of these cinematic ‘building blocks’ and discusses how it is used to reshape domestic space in two contrasting films. As each filmmaking process is clarified, its related critical theory is challenged and reassessed. The figure of a woman in a house is familiar, culturally as well as cinematically. These films take this trope as their starting point and subject it to a series of provocations, manipulations, and mutations. As well as written close analysis, the thesis contains an element of practice as research. A video essay made with found footage from all ten films was presented as a three-screen installation. This work is reflected upon in the thesis, and the theoretical potential of videographic practice as a tool in film studies is discussed. An online link to the installation, reconfigured as a video essay, is an integral part of this thesis. The films show home as both a material and an imaginative space, organised and shaped by the interiority of its inhabitants. Sometimes the home is a magical space warped by unconscious drives. At others, it is an everyday space which follows spatial logic. Yet even in these apparently more transparent texts, psychic drives and emotional urgencies are played out spatially. Drawing upon spatial and feminist film theory, the thesis aims to offer a fresh commentary into how the home is represented onscreen.

description: A major challenge in specifying design requirements for policy-based seismic retrofits is ensuring that the desired performance enhancements are achieved across a portfolio of buildings with diverse structural characteristics and hazard. To address this challenge, a modular optimization methodology is developed. A prediction module uses machine learning-based surrogate models as compact statistical links between building structural characteristics and seismic performance outcomes. The optimization module uses regionally targeted objective functions to determine the retrofit enhancements that achieve the most desirable aggregated performance outcome for the portfolio of buildings. Lastly, the evaluation module benchmarks the performance of the optimized retrofit scheme against the existing inventory as well as more conventional retrofit approaches. The ability of the framework to balance the need for effective (improved performance) and efficient (minimizing cost) retrofits is demonstrated by applying it to the inventory of buildings under the purview of the Los Angeles Soft-Story Ordinance.

description: We calculate the helicity and polarization correlation functions in the Einstein-Podolsky-Rosen-type experiments with relativistic vector bosons. We show that the linear polarization correlation function in the appriopriately chosen state in the massless limit is the same as the correlation function in the scalar two-photon state. We show also that the polarization correlation function violate the Clauser-Horne-Shimony-Holt inequality and that the degree of this violation can increase with the particle momentum.

description: Luminous and ultraluminous infrared galaxies (LIRGs and ULIRGs) dominate the star formation rate budget of the universe at z > 1, yet no local measurements of their heavy element abundances exist. We measure nuclear or near-nuclear oxygen abundances in a sample of 100 star-forming LIRGs and ULIRGs using new, previously published, and archival spectroscopy of strong emission lines (including [O II] 3727, 3729 A) in galaxies with redshifts ~ 0.1. When compared to local emission-line galaxies of similar luminosity and mass (using the near-infrared luminosity-metallicity and mass-metallicity relations), we find that LIRGs and ULIRGs are under-abundant by a factor of two on average. As a corollary, LIRGs and ULIRGs also have smaller effective yields. We conclude that the observed under-abundance results from the combination of a decrease of abundance with increasing radius in the progenitor galaxies and strong, interaction- or merger-induced gas inflow into the galaxy nucleus. This conclusion demonstrates that local abundance scaling relations are not universal, a fact that must be accounted for when interpreting abundances earlier in the universe's history when merger-induced star formation was the dominant mode. We use our local sample to compare to high-redshift samples and assess abundance evolution in LIRGs and ULIRGs. We find that abundances in these systems increased by ~0.2 dex from z ~ 0.6 to z ~ 0.1. Evolution from z ~ 2 submillimeter galaxies to z ~ 0.1 ULIRGs also appears to be present, though uncertainty due to spectroscopic limitations is large.

description: Recently Li and Xia have proposed a transmission scheme for wireless relay networks based on the Alamouti space time code and orthogonal frequency division multiplexing to combat the effect of timing errors at the relay nodes. This transmission scheme is amazingly simple and achieves a diversity order of two for any number of relays. Motivated by its simplicity, this scheme is extended to a more general transmission scheme that can achieve full cooperative diversity for any number of relays. The conditions on the distributed space time block code (DSTBC) structure that admit its application in the proposed transmission scheme are identified and it is pointed out that the recently proposed full diversity four group decodable DSTBCs from precoded co-ordinate interleaved orthogonal designs and extended Clifford algebras satisfy these conditions. It is then shown how differential encoding at the source can be combined with the proposed transmission scheme to arrive at a new transmission scheme that can achieve full cooperative diversity in asynchronous wireless relay networks with no channel information and also no timing error knowledge at the destination node. Finally, four group decodable distributed differential space time block codes applicable in this new transmission scheme for power of two number of relays are also provided.

description: Learning behavior mechanism is widely anticipated in managed settings through the formal syllabus. However, heading for learning stimulus whilst daily mobility practices through urban transit is the novel feature in learning sciences. Theory of planned behavior (TPB), technology acceptance model (TAM), and service quality of transit are conceptualized to assess the learning behavioral intention (LBI) of commuters in Greater Kuala Lumpur. An online survey was conducted to understand the LBI of 117 travelers who use the technology to engage in the informal learning process during daily commuting. The results explored that all the model variables i.e., perceived ease of use, perceived usefulness, service quality, and subjective norms are significant predictors of LBI. The perceived usefulness of learning during traveling and transit service quality has a vibrant impact on LBI. The research will support the informal learning mechanism from commuters point of view. The study is a novel contribution to transport and learning literature that will open the new prospect of research in urban mobility and its connotation with personal learning and development.

La presenza dell’enzima PNMT nelle cellule cromaffini del tritone è stata dimostrata sia per via immunocitochimica che mediante ibridazione in situ. I risultati del trattamento con FSH hanno evidenziato un’influenza inibitoria di quest’ultimo sull’enzima PNMT, e quindi una sensibilità dell’enzima ai fattori che regolano il ciclo riproduttivo di questa specie. Questo risultato confermerebbe la relazione tra ciclo funzionale delle cellule cromaffini e ciclo riproduttivo, già supposta a seguito di precedenti ricerche. Infine, mediante il sequenziamento dell’mRNA, la candidata ha potuto confrontare le sequenze nucleotidiche e aminoacidiche dedotte con quelle adrenaliche note (uomo, bovino, ratto e topo). Il confronto ha evidenziato un 17% di omologia, localizzato prevalentemente tra i nucleotidi 241-421, e probabilmente relativo alle funzioni più essenziali dell’enzima, presumibilmente più conservate nel corso dell’evoluzione.
Il lavoro sperimentale ha richiesto l’utilizzo delle tecniche di base di microscopia ottica e elettronica, nonché di immunocitochimica. Inoltre,  tecniche di biologia molecolare, quali elettroforesi su gel, ibridazione in situ, estrazione di acidi nucleici, screening di library genomiche e di cDNA, PCR e RT-PCR, sequenziamento di frammenti di cDNA, clonaggi in vettori diversi.

description: The use of hydrogen as a clean and renewable alternative to fossil fuels requires a suite of flammability mitigating technologies, particularly robust sensors for hydrogen leak detection and concentration monitoring. To this end, we have developed a class of lightweight optical hydrogen sensors based on a metasurface of Pd nano-patchy particle arrays, which fulfills the increasing requirements of a safe hydrogen fuel sensing system with no risk of sparking. The structure of the optical sensor is readily nano-engineered to yield extraordinarily rapid response to hydrogen gas (<3 s at 1 mbar H$_{2}$) with a high degree of accuracy (<5%). By incorporating 20% Ag, Au or Co, the sensing performances of the Pd-alloy sensor are significantly enhanced, especially for the Pd$_{80}$Co$_{20}$ sensor whose optical response time at 1 mbar of H$_{2}$ is just ~0.85 s, while preserving the excellent accuracy (<2.5%), limit of detection (2.5 ppm), and robustness against aging, temperature, and interfering gases. The superior performance of our sensor places it among the fastest and most sensitive optical hydrogen sensors.
Optical and infrared spectra of some unstable molecules

Publisher: name: University of British Columbia

description: Some unstable gaseous molecules, cobalt oxide (CoO), niobium nitride (NbN) and aminoborane (NH₂BH₂), were studied by high resolution optical spectroscopy. A portion of the "red" system of CoO, from 7000 Å to 5800 Å, was measured using laser induced fluorescence techniques. Three bands of the system, with origins at 6338 Å, 6411 Å and 6436 Å, were rotationally analyzed. The lower levels of these parallel bands are the Ω = 7/2 and 5/2 spin-orbit components of a ⁴∆i electronic state. Available evidence indicates that this is the ground state of the molecule; its bond length is 1.631 Å. This work completes the determination of the ground state symmetries for the entire series of first row diatomic transition metal oxides. The hyperfine structure in the ground state is very small, supporting a σ²δ³π² electron configuration. The upper state, assigned as σδ³π²σ*, has large positive hyperfine splittings that follow a case (aβ) pattern; it is heavily perturbed, both rotationally and vibrationally. The sub-Doppler spectrum of the ³Φ₋³∆ system of NbN was measured by intermodulated fluorescence techniques, and the hyperfine structure analyzed. Second order spin-orbit interactions have shifted the ³Φ₃₋³∆₂ subband 40 cm⁻¹ to the blue of its central first order position. The perturbations to the spin-orbit components were so extensive that five hyperfine constants, rather than three, were required to fit the data to the case (a) Hamiltonian. The ³∆₋³Φ system of NbN is the first instance where this has been observed. The magnetic hyperfine constants indicate that all components of the ³∆ and ³Φ spin orbit manifolds may be affected, though the ³∆ state interacts most strongly, presumably by the coupling of the ³∆₂ component with the ¹∆ state having the same configuration. The Fermi contact interactions in the ³∆ substates are large and positive, consistent with a σ¹δ¹ configuration. In the ³Φ state the (b + c) hyperfine constants are negative, as expected from a π¹δ¹ configuration. The ³∆ and ³Φ bond lengths are 1.6618 Å and 1.6712 Å, respectively, which are intermediate between those of ZrN and MoN. The Fourier transform infrared spectrum of the V7 BH₂ wagging fundamental of NH₂BH₂ was rotationally analyzed. A set of effective rotational and centrifugal distortion constants was determined, but the band shows extensive perturbations by Coriolis interactions with the nearby V5 and V11 fundamentals. A complete analysis could not be made without an analysis of the V5-V7-V11 Coriolis interactions, which is currently not possible because the very small dipole derivative of the V5 vibration has prevented its analysis.

description: We apply an analytical model for anisotropic, colliding Bose-Einstein condensates in a spontaneous four wave mixing geometry to evaluate the second order correlation function of the field of scattered atoms. Our approach uses quantized scattering modes and the equivalent of a classical, undepleted pump approximation. Results to lowest order in perturbation theory are compared with a recent experiment and with other theoretical approaches.

Where, oh where has the r-process gone?

description: We present a review of the possible sources for r-process nuclei. It is known that there is as yet no self-consistent mechanism to provide abundant neutrons for a robust r-process in the neutrino-driven winds from nascent neutron stars. We consider that the heavy r-nuclei with mass numbers A>130 (Ba and above) cannot be produced in the neutrino-driven winds. Nonetheless, the r-process and the neutrino-driven winds may be directly or indirectly related by some unknown additional mechanism, which, for example, could provide ejecta with very short dynamic timescales of <0.004 s. This undetermined mechanism must supply a neutron source within the same general stellar sites that undergo core collapse to produce the neutron star. Observational data on low-metallicity stars in the Galactic halo show that sites producing the heavy r-nuclei do not produce Fe or any other elements between N and Ge. Insofar as a forming neutron star is key to producing the heavy r-nuclei, then the only possible sources are supernovae resulting from collapse of O-Ne-Mg cores or accretion-induced collapse of white dwarfs, neither of which produce the elements of the Fe group or those of intermediate mass (above C and N). Using a template star with high enrichments of heavy r-nuclei and another with low enrichments we develop a two-component model based on the abundances of Eu (from sources for heavy r-nuclei) and Fe (from Fe core-collapse supernovae). This model gives very good quantitative predictions for the abundances of all the other elements in those metal-poor stars with [Fe/H]

description: We derive the form of the cross-Kerr interaction in a four-level atomic system in the N-configuration. We use time-independent perturbation theory to calculate the eigenenergies and eigenstates of the Schrodinger equation for the system. The system is considered as a perturbation of a Raman resonant three-level lambda scheme for which exact solutions are known. We show that within the strong control field limit the cross-Kerr interaction can arise between two weak probe fields. The strength of this nonlinear coupling is several orders of magnitude larger than that achievable using optical fibres.

description: Explicit expressions for quantum fluctuations of energy in subsystems of a hot relativistic gas of spin-$1/2$ particles are derived. The results depend on the form of the energy-momentum tensor used in the calculations, which is a feature described as pseudo-gauge dependence. However, for sufficiently large subsystems the results obtained in different pseudo-gauges converge and agree with the canonical-ensemble formula known from statistical physics. As different forms of the energy-momentum tensor of a gas are a priori equivalent, our finding suggests that the concept of quantum fluctuations of energy in very small thermodynamic systems is pseudo-gauge dependent. On the practical side, the results of our calculations determine a scale of coarse graining for which the choice of the pseudo-gauge becomes irrelevant.

Valutazione quali – quantitativa di patata allevata con tecnica di produzione biologica e convenzionale

description: La qualità delle produzioni orticole è senza dubbio il principale obbiettivo dell’agricoltura moderna. Tuttavia il concetto di qualità rimane di non facile definizione. In Italia, dal secondo dopoguerra ad oggi, il concetto di qualità degli ortaggi per il consumo fresco ha subito una profonda evoluzione. Dai parametri di qualità strettamente commerciali ed organolettici, il concetto si è allargato fino a raggiungere un ambito ampio ed articolato che spazia dalle caratteristiche igienico-sanitarie a quelle salutistiche e nutrizionali intrinseche, fino ad un concetto “etico” di qualità legato al processo produttivo. Il cambiamento dello stile di vita, dei gusti, l’aumento del reddito, l’innalzamento del livello di istruzione e del tenore di vita hanno determinato il fenomeno, ancora fortemente dinamico e mutevole. In tal senso si assiste in questi ultimi anni ad una forte affermazione del metodo di produzione biologico, in risposta anche ad una notevole espansione della richiesta di prodotti in grado di dare sufficienti garanzie ad un consumatore sempre più attento.
Lo scopo del lavoro è stato quello di valutare l’effetto del sistema di produzione (“biologico” e “convenzionale”) al variare di alcuni fattori agronomici: quantitativo di azoto utilizzato, volume d’irrigazione, cultivar ed epoche di impianto sulla resa e su alcune caratteristiche qualitative della patata.
I risultati sperimentali, ottenuti in questo lavoro, hanno evidenziato, dal punto di vista qualitativo, delle differenze significative dovute al sistema di conduzione (biologico/convenzionale). Dal punto di vista chimico è stato possibile rilevare che le patate “convenzionali” hanno, rispetto a quelle “biologiche”, un contenuto di nitrati più alto dovuto, probabilmente, alla maggiore disponibilità di azoto prontamente assimilabile da parte delle piante, ciò per la diversa tipologia di concimi impiegati (chimici/organici).
Anche in merito al contenuto in polifenoli, le patate ottenute tramite coltivazione biologica hanno mostrato valori più elevati. Inversamente a quanto osservato per l’attività antiossidante idrofila, il contenuto di polifenoli aumenta dopo la cottura (con la buccia) sia nelle patate coltivate in biologico che in maniera convenzionale. Questo risultato potrebbe essere spiegato con il fatto che, alcuni acidi fenolici sono presenti nello strato esterno della patata, cioè la buccia (Sharma e Le Maguer, 1996). Durante la cottura in acqua, dette sostanze fenoliche sembrerebbero essere rilasciate dalla buccia alla polpa del tubero.

description: Electron correlation in a quantum many-body state appears as peculiar scattering behaviour at its boundary, symbolic of which is Andreev reflection at a metal-superconductor interface. Despite being fundamental in nature, dictated by the charge conservation law, however, the process has had no analogues outside the realm of superconductivity so far. Here, we report the observation of an Andreev-like process originating from a topological quantum many-body effect instead of superconductivity. A narrow junction between fractional and integer quantum Hall states shows a two-terminal conductance exceeding that of the constituent fractional state. This remarkable behaviour, while theoretically predicted more than two decades ago but not detected to date, can be interpreted as Andreev reflection of fractionally charged quasiparticles. The observed fractional quantum Hall Andreev reflection provides a fundamental picture that captures microscopic charge dynamics at the boundaries of topological quantum many-body states.

description: We study selected aspects of Theoretical Physics confronting some key issues related to the fundamental interactions along the line of Black Holes (BHs) and Attractors and its thread may be found in the concepts of Supersymmetry, Supergravity and Holography which encompass all of String theory and Quantum gravity. Then we also had an encounter with maximally symmetric spaces in General Relativity such as de Sitter and we did some  significant computation in this backdrop which is tempting to pursue keeping in mind the recent observational data in favor of inflationary picture of the Universe.
METODICHE DI IMAGING NEI TUMORI MALIGNI MULTIPLI PRIMITIVI

description: I tumori maligni multipli primitivi (TMMP) sono un argomento affascinante e di grande attualità.
Dopo la prima segnalazione alla fine del XIX secolo di Billroth (1889) di un paziente con neoplasie multiple, al quale fu diagnosticato un carcinoma gastrico dopo l’asportazione di un epitelioma spinocellulare dell’orecchio esterno, i TMMP rimasero solo una curiosità medica con sporadiche segnalazioni fino alla classificazione di Warren e Gates [56] del 1932, che selezionarono 1259 casi tra quelli riportati in letteratura e quelli riscontrati dai loro esami autoptici.
La loro incidenza è attualmente in aumento e sarà sicuramente in crescita nei prossimi anni per diversi fattori, quali l’allungamento della vita media, la maggior incidenza di trattamenti in fase precoce, la qualità del follow-up oncologico  e, non in ultimo, il miglioramento prognostico di molti tumori grazie al rilevante progresso delle terapie oncologiche (chirurgiche e mediche) con percentuali di guarigioni e di sopravvivenze inimmaginabili in passato (sopravvivenza complessiva a 5 anni del 79% per i tumori insorti in età pediatrica e del 66% per quelli dell’adulto)[19]
Una parte di questi pazienti può sviluppare ulteriori neoplasie per motivi apparentemente casuali (ovvero al momento non comprensibili alla luce delle attuali conoscenze biomediche), o per fattori definiti: genetici, ambientali, ormonali, immunologici o iatrogeni (conseguenti alle stesse terapie oncologiche).

Lessons learned from dynamic analyses of Mexico City and applied to Richmond B.C.

description: The implications of the acceleration data recorded during the September 19, 1985 Mexican earthquake for seismic design in Canada are investigated by determining if the deep deposits of the Fraser Delta could cause large amplification of earthquake motions. The conditions for amplification of low level incoming ground motions at deep sites are identified; in particular, the critical role of variation in shear modulus with shear strain. The current procedure for determining site specific ground motions is evaluated and major sources of uncertainty in the results identified. Criteria for selecting representative input motions for site response studies are recommended based on analyses of Mexico City sites. A comparative study of sites in the Fraser Delta area of British Columbia showed that offshore subduction earthquakes should be considered when developing design spectra for deep sites in the Delta.
