description: Amongst the most popular explanations for dark energy are modified theories of gravity. The galaxy overdensity and peculiar velocity fields help us to constrain the growth rate of structure and distinguish different models of gravity. We introduce an improved method for constraining the growth rate of structure with the galaxy overdensity and peculiar velocity fields. This method reduces the modelling systematic error by accounting for the wide-angle effect and the zero-point calibration uncertainty during the modelling process. We also speed up the posterior sampling by around 30 times by first calculating the likelihood at a small number of fiducial points and then interpolating the likelihood values during MCMC sampling. We test the new method on mocks and we find it is able to recover the fiducial growth rate of structure. We applied our new method to the SDSS PV catalogue, which is the largest single peculiar velocity catalogue to date. Our constraint on the growth rate of structure is \(fσ_8 = 0.405_{-0.071}^{+0.076}\) (stat) \(\pm 0.009\) (sys) at the effective redshift of 0.073. Our constraint is consistent with a Planck 2018 cosmological model, \(fσ_8 = 0.448\), within one standard deviation. Our improved methodology will enable similar analysis on future data, with even larger sample sizes and covering larger angular areas on the sky.

description: In many of the experimental systems that may host Majorana zero modes, a so-called chiral symmetry exists that protects overlapping zero modes from splitting up. This symmetry is operative in a superconducting nanowire that is narrower than the spin-orbit scattering length, and at the Dirac point of a superconductor/topological insulator heterostructure. Here we show that chiral symmetry strongly modifies the dynamical and spectral properties of a chaotic scatterer, even if it binds only a single zero mode. These properties are quantified by the Wigner-Smith time-delay matrix $Q=-i\hbar S^\dagger dS/dE$, the Hermitian energy derivative of the scattering matrix, related to the density of states by $ρ=(2π\hbar)^{-1}\,{\rm Tr}\,Q$. We compute the probability distribution of $Q$ and $ρ$, dependent on the number $ν$ of Majorana zero modes, in the chiral ensembles of random-matrix theory. Chiral symmetry is essential for a significant $ν$-dependence.

description: Quando gli autori diventano dei classici, ciò non accade semplicemente per via della loro originalità, ma piuttosto in virtù dell’influsso, delle conseguenze e degli effetti della loro ricerca. Al contrario di quanto pensino i più, tuttavia, siffatte influenze non emergono in modo particolare nei discepoli degli autori stessi, quanto piuttosto in quegli interpreti che non per forza ne continuano il pensiero in maniera fedele. L’impatto di Martin Heidegger su Paul Ricœur, Jacques Derrida e Richard Rorty risulta, per esempio, molto più evidente dell’influenza che egli esercita sui suoi stessi studenti, vale a dire Hannah Arendt, Hans-Georg Gadamer ed Ernst Tugendhat.

description: Gianni Vattimo ha elaborato l’estetica e la teoria dell’arte del «pensiero debole» soprattutto in alcuni articoli pubblicati nella «Rivista di Estetica» (della quale è stato direttore). Parte di questi saggi è stata poi raccolta nella seconda sezione di una delle sue opere centrali, La fine della modernità, sezione intitolata, significativamente, La verità dell’arte. Le diverse questioni discusse da Vattimo sono infatti attraversate dal filo conduttore del problema della verità dell’arte, nell’epoca del nichilismo, della fine della storia e del mondo estetizzato dei mass media.

description: Let $Γ$ be an $L$-shape arc consisting of 2 line segments that meet at an angle different from $π$ in the complex $z$-plane $\CC$. This paper is to investigate the behavior of the polynomial interpolants at the Fejér points, defined by $\{z_{n,k} = ψ(e^{i(2kπ+ θ)/(n+1)})\}$ for any choice of $θ$. In this regard, we recall that for the interval [-1, 1], the Fejér points $\{z_{n,k} = ψ^*(e^{i(2k+1)π/(n+1)})\}$ agree with the Chebyshev points and that the Chebyshev points are most commonly used as nodes for Lagrange polynomial interpolation. On the other hand, numerical experimentation demonstrates that for a typical open $L$-shape arc $Γ$, the Lebesgue constants tend to $\infty$ at the rate of $O((log(n))^2)$, as the polynomial degree $n$ increases, while the $A_{p}$-weight conditions for the Fejér points $\{z_{n,k}\}$ do not carry over from [-1, 1] to a truly $L$-shape arc. Further numerical experiments also demonstrate that the least upper bounds of the Marcinkiewicz-Zygmund inequalities for the canonical Lagrange interpolation polynomials at $\{z_{n,k}\}$ seem to grow at the rate of $n^β$, for some $β>0$ that depends on $p >1$.

ADVANCING BIO DOSIMETRY FOR RADIATION ACCIDENTS AND TREATMENT WITH UPDATED CALIBRATION FOR HIGH-ENERGY LINAC BEAMS

Subjects: Medical radiation, lymphocytes, chromosomal abnormalities, biodosimetry, radiobiological impact

description: This research investigates the effects of medical radiation on human lymphocytes, focusing on chromosomal abnormalities induced by X-ray photon irradiation at energies of 6 and 10 MV. The study explores the dose-dependent relationship between absorbed doses (ranging from 0.5 to 8 Gy) and the frequency of chromosomal aberrations, with dose rates varying from 5.50 to 23.08 Gy/min. A comparison with 60Co gamma radiation was conducted using standard cytogenetic methods to produce metaphases and analyze chromosomal damage. The findings revealed significant variations in aberration frequencies across different irradiation techniques, with the flattening filter-free (FFF) mode demonstrating a stronger radiobiological impact than the conventional flattening filter (FF) mode. A linear-quadratic dose-response calibration curve was constructed to determine the relative biological effectiveness (RBE) of the different radiation modalities. The average RBE values were found to be 1.28 for 60Co, 1.11 for 6 MV FFF, and ranged from 0.79 to 0.92 for 10 MV FFF. These results highlight the importance of updating biodosimetry calibration curves to account for higher radiation energies and dose rates, particularly in therapeutic contexts. The study emphasizes the need for precise biodosimetry in situations involving unintentional radiation overdoses, as accurate calibration curves are crucial for quantifying such events, especially in hypofractionated treatments

description: Background: Androgen receptor signaling is crucial to prostate cancer aggressiveness. Members of the solute carrier family of the organic anion transporting peptides (SLCO) are potential regulators of androgen availability in prostate tissue. It remains unknown whether genetic variations in SLCOs contribute to the differences in prostate cancer aggressiveness in African Americans (AA) and European Americans (EA). Methods: SNPs in 11 SLCO members were selected, with addition of 139 potentially functional SNPs and 128 ancestry informative markers. A total of 1,045 SNPs were genotyped and analyzed in 993 AAs and 1,057 EAs from the North Carolina–Louisiana Prostate Cancer Project. Expression and cellular localization of SLCOs were examined using qRT-PCR, IHC, and in situ RNA hybridization in independent sets of prostate cancer cases. Results: Significant associations with prostate cancer characteristics were found for SNPs in SLCO2A1 and SLCO5A1. The associations differed by race (Pinteraction < 0.05). SNPs in SLCO2A1 were associated with reduced tumor aggressiveness and low Gleason score in AAs; whereas, SNPs in SLCO5A1 were associated with high clinical stage in EAs. In prostate tissue, SLCO2A1 and SLCO5A1 were the most expressed SLCOs at the mRNA level and were expressed predominantly in prostate endothelial and epithelial cells at the protein level, respectively. Conclusions: SLCO2A1 and SLCO5A1 play important but different roles in prostate cancer aggressiveness in AAs versus EAs. Impact: The finding calls for consideration of racial differences in biomarker studies of prostate cancer and for investigations on functions of SLCO2A1 and SLCO5A1 in prostate cancer.

description: The object of this investigation was to define the nature of the immune responses of mice that had been given a sublethal pulmonary infection with Bordetella pertussis - an infection which shares many features with whooping cough in man. Both serum antibodies and local, secretory antibodies were studied the latter being sampled as tracheobronchial washings (TBW). A particular focus of interest was in those responses that were directed against biologically active components of B. pertussis and in those responses involved in passive protective activity against intracerebral and sublethal intranasal challenge with live B. pertussis.

description: «Non è sempre necessario che il vero prenda corpo; è già sufficiente che aleggi nei dintorni come spirito e provochi un accordo, come quando il suono delle campane fluttua nell’atmosfera grave e amichevole» (Heidegger 1969: 27). In questo passo di Heidegger (il quale, tra l’altro, a sua volta cita Goethe), Vattimo da un lato saluta la riscoperta, non solo metaforica, della spazialità, dall’altro avverte però il rischio di una deriva misticheggiante (Vattimo 1985: 87). “Urbanizzando” tale valorizzazione dello spazio, Vattimo preferisce farla interagire, infatti, con l’idea gadameriana dell’architettura come arte che “fa spazio” alle altre (Gadamer 1960: 159), nell’intento di sottrarre ogni enfatica inauguralità alla nozione heideggeriana di Erde. Nel gioco vertiginoso suggerito da Heidegger tra la località disposta dall’opera, ossia il nuovo ordinamento spaziale suggerito dal porsi in primo piano dell’opera plastica, e la «libera vastità della contrada» (Heidegger 1969: 23), cioè la periferia (l’aldilà contestuale) dell’opera, Vattimo cerca, in ultima analisi, una conferma alla tesi dell’apertura della verità come sfondo (o addirittura “sfondamento”), come traspropriazione e «presa di congedo dall’essere metafisico e dai suoi caratteri forti» (Vattimo 1985: 94).

description: Optical Ising machines promise to solve complex optimization problems with an optical hardware acceleration advantage. Here we study the ground state properties of a nonlinear optical Ising machine realized by spatial light modulator, Fourier optics, and second harmonic generation in a nonlinear crystal. By tuning the ratio of the light intensities at the fundamental and second harmonic frequencies, we experimentally observe two distinct ferromagnetic-to-paramagnetic phase transitions: a second-order phase transition where the magnetization changes to zero continuously and a first-order phase transition where the magnetization drops to zero abruptly as the effective temperature increases. Our experimental results are corroborated by a numerical simulation based on the Monte Carlo Metropolis-Hastings algorithm, and the physical mechanism for the distinct phase transitions can be understood with a mean-field theory. Our results showcase the great flexibility of the nonlinear optical Ising machine, which may find important potential applications in solving combinatorial optimization problems.

description: In this article, we study the superradiance of charged scalar fields on the sub-extremal Reissner-Nordstrom metric, a mechanism by which such fields can extract energy from a static spherically symmetric charged black hole. A geometrical way of measuring the amount of energy extracted is proposed. Then we investigate the question numerically. The toy-model and the numerical methods used in our simulations are presented and the problem of long time measurement of the outgoing energy flux is discussed. We provide a numerical example of a field exhibiting a behaviour analogous to the Penrose process: an incoming wave packet which splits, as it approaches the black hole, into an incoming part with negative energy and an outgoing part with more energy than the initial incoming one. We also show another type of superradiant solution for which the energy extraction is more important. Hyperradiant behaviour is not observed, which is an indication that the Reissner-Nordstrom metric is linearly stable in the sub-extremal case.

description: For Lagrange polynomial interpolation on open arcs $X=γ$ in $\mathbb{C}$, it is well-known that the Lebesgue constant for the family of Chebyshev points ${\bf{x}}_n:=\{x_{n,j}\}^{n}_{j=0}$ on $[-1,1]\subset \mathbb{R}$ has growth order of $O(log(n))$. The same growth order was shown in [45] for the Lebesgue constant of the family ${\bf {z^{**}_n}}:=\{z_{n,j}^{**}\}^{n}_{j=0}$ of some properly adjusted Fejér points on a rectifiable smooth open arc $γ\subset \mathbb{C}$. On the other hand, in our recent work [15], it was observed that if the smooth open arc $γ$ is replaced by an $L$-shape arc $γ_0 \subset \mathbb{C}$ consisting of two line segments, numerical experiments suggest that the Marcinkiewicz-Zygmund inequalities are no longer valid for the family of Fejér points ${\bf z}_n^{*}:=\{z_{n,j}^{*}\}^{n}_{j=0}$ on $γ$, and that the rate of growth for the corresponding Lebesgue constant $L_{\bf {z}^{*}_n}$ is as fast as $c\,log^2(n)$ for some constant $c>0$. The main objective of the present paper is 3-fold: firstly, it will be shown that for the special case of the $L$-shape arc $γ_0$ consisting of two line segments of the same length that meet at the angle of $π/2$, the growth rate of the Lebesgue constant $L_{\bf {z}_n^{*}}$ is at least as fast as $O(Log^2(n))$, with $\lim\sup \frac{L_{\bf {z}_n^{*}}}{log^2(n)} = \infty$; secondly, the corresponding (modified) Marcinkiewicz-Zygmund inequalities fail to hold; and thirdly, a proper adjustment ${\bf z}_n^{**}:=\{z_{n,j}^{**}\}^{n}_{j=0}$ of the Fejér points on $γ$ will be described to assure the growth rate of $L_{{\bf z}_n^{**}}$ to be exactly $O(Log^2(n))$.

description: Nella seconda metà degli anni Ottanta Gianni Vattimo ipotizzava quanto segue: «oggi, se c’è un idioma comune della filosofia e della cultura, esso va individuato nell’ermeneutica». E ancora a metà degli anni Novanta riteneva che questa ipotesi non fosse stata smentita. Valutare la portata e la tenuta di questa tesi non è però un compito semplice. In primo luogo, non è facile dire quanto essa si presti a essere discussa al di fuori del suo contesto. Tanto nel saggio Ermeneutica come koiné quanto, più tardi, nel primo capitolo di Oltre l’interpretazione la tesi della koiné si configura non propriamente come un’ipo- tesi storiografica, ma come punto di partenza di un impegnativo (e aperta- mente zeitgeistlich o, meglio, seinsgeschichtlich) discorso teorico.

description: Prenderò in esame un periodo della produzione di Gianni Vattimo compreso fra il 1985 (La fine della modernità) e il 1994 (Oltre l’interpretazione), all’interno del quale trovano posto alcuni grandi saggi pubblicati sull’annuario di Filosofia dell’editore Laterza: Metafisica, violenza, secolarizzazione (1987), Ontologia dell’attualità (1988), La verità dell’ermeneutica (1989), Ricostruzione della razionalità (1992), Diritto all’argomentazione (1993). Questa scelta dipende, oltre che dall’ovvia esigenza di una delimitazione di campo, anche da due motivazioni di carattere teorico: in primo luogo ritengo che siano questi gli anni in cui Vattimo giunge all’elaborazione di quelle categorie centrali che conserveranno nei successivi sviluppi del suo pensiero il valore di riferimenti definitivi; in secondo luogo trovo in questi saggi la volontà di pensare fino in fondo un modello ermeneu- tico di «razionalità» contrapposto a quello della metafisica fondazionalistica, e tale da scongiurare il pericolo di un confinamento dell’ermeneutica tra le pratiche discorsive non suscettibili di un trattamento argomentativo.

description: Our study describes breast cancer risk loci using a cross-ancestry GWAS approach. We first identify variants that are associated with breast cancer at P < 0.05 from African ancestry GWAS meta-analysis (9241 cases and 10193 controls), then meta-analyze with European ancestry GWAS data (122977 cases and 105974 controls) from the Breast Cancer Association Consortium. The approach identifies four loci for overall breast cancer risk [1p13.3, 5q31.1, 15q24 (two independent signals), and 15q26.3] and two loci for estrogen receptor-negative disease (1q41 and 7q11.23) at genome-wide significance. Four of the index single nucleotide polymorphisms (SNPs) lie within introns of genes (KCNK2, C5orf56, SCAMP2, and SIN3A) and the other index SNPs are located close to GSTM4, AMPD2, CASTOR2, and RP11-168G16.2. Here we present risk loci with consistent direction of associations in African and European descendants. The study suggests that replication across multiple ancestry populations can help improve the understanding of breast cancer genetics and identify causal variants.

description: Sarà ancora possibile, dopo la morte di Dio, parlare di imperativi morali, di leggi non fondate sull’arbitrio, e di un orizzonte emancipativo della politica?». La crisi della metafisica ha avuto pesanti conseguenze sul pensiero della politica. Da sempre, la metafisica si è assunta il compito di reperire i principi sulla base dei quali l’agire poteva trarre i propri fini e la propria legittimazione: il pensiero post-metafisico è costretto, ora, a porre il rapporto tra teoria e prassi su basi differenti rispetto al passato e a pensare una politica priva di fondamento. La libertà si è rivelata un’arma a doppio taglio: svanita la possibilità di derivare la prassi dalla teoria cresce la libertà della politica, ma si mostra parimenti l’assenza di criteri di giudizio sulle cose del mondo. La teoria politica post-metafisica è sembrata andare incontro a due aporie, apparentemente antitetiche, in realtà entrambe figlie di due interpretazioni egualmente unilaterali del pensiero di Heidegger. Da un lato una posizione “anarchica”, nata da una deriva puramente prassistica della decostruzione della metafisica: “è finita la filosofia, si agisca”. Dall’altro la posizione di coloro che riducono l’agire al pensiero: mostrano che il pensiero autentico è azione, ma poi finiscono per identificare i due termini, come se il pensiero fosse “tutta” l’azione. La necessità di sfuggire a questa duplice impasse – la possibilità, in altre parole, di un pensiero aperto alla dimensione collettiva, cui faccia da contraltare un agire non cieco – è alla base della ritrovata centralità, nel panorama filosofico recente, di temi legati alla dimensione pubblica, all’etica e alla politica.

description: We develop a topological theory for disordered Weyl semimetals in the framework of gauge invariance of replica formalism and boundary-bulk correspondence of Chern insulators. An anisotropic topological $θ$-term is analytically derived for the effective non-linear sigma model. It is this nontrivial topological term that ensures the bulk transverse transport of Weyl semimetals to be robust against disorders. Moreover, we establish a general diagram that reveals the intrinsic relations among topological terms in the non-linear sigma models and gauge response theories respectively for $(2n + 2)$-dimensional topological insulators, $(2n+1)$-dimensional chiral fermions, $(2n+1)$-dimensional chiral semimetals, and $(2n)$-dimensional topological insulators with $n$ being a positive integer.

description: Matter-free lattice gauge theories (LGTs) provide an ideal setting to understand confinement to deconfinement transitions at finite temperatures, which is typically due to the spontaneous breakdown (at large temperatures) of the centre symmetry associated with the gauge group. Close to the transition, the relevant degrees of freedom (Polyakov loop) transform under these centre symmetries, and the effective theory only depends on the Polyakov loop and its fluctuations. As shown first by Svetitsky and Yaffe, and subsequently verified numerically, for the $U(1)$ LGT in $(2+1)$-d the transition is in the 2-d XY universality class, while for the $Z_2$ LGT, it is in the 2-d Ising universality class. We extend this classic scenario by adding higher charged matter fields, and show that the notion of universality is generalized such that the critical exponents $γ, ν$ can change continuously as a coupling is varied, while their ratio is fixed to the 2-d Ising value. While such weak universality is well-known for spin models, we demonstrate this for LGTs for the first time. Using an efficient cluster algorithm, we show that the finite temperature phase transition of the $U(1)$ quantum link LGT in the spin $S=\frac{1}{2}$ representation is in the 2-d XY universality class, as expected. On the addition of $Q = \pm 2e$ charges distributed thermally, we demonstrate the occurrence of weak universality.

Etica e critica dell’identità nell’orizzonte del postmoderno
Creators: name: Missana, Eleonora
Publisher: name: Trópos

description: Fin dalle origini, da quando cioè, tra la fine degli anni ’70 e l’inizio degli anni ’80, viene formulato in termini filosofici, il concetto di postmoderno innesca un dibattito, dai toni spesso infuocati, sul significato etico-politico della proclamazione della fine della modernità. In particolare in seguito alla pubblicazione, nel 1979, di La condition postmoderne di J. F. Lyotard, si levano numerose voci a difesa di quella tradizione illuministica e progressista della modernità di cui il postmoderno dichiarerebbe la disfatta lasciando l’epoca contemporanea preda di un facile relativismo buono per i privilegiati e i vincenti nella competizione mondiale ma incapace di fronteggiare le ingiustizie che ancora regnano nel mondo. La «gaia rassegnazione» che in parte pervade le società occidentali negli anni ’80 poteva in effetti offrire argomenti a favore di questa visione sostenuta in modo esemplare dal filosofo tedesco J. Habermas. Non mancano tuttavia, già in quel primo periodo, posizioni come quella espressa da G. Vattimo, che emerge come uno dei principali pensatori del postmoderno, e propone una riflessione sul suffisso «post» a partire dalla nozione heideggeriana di Verwindung piuttosto che da quella hegeliana di Uberwindung o Aufhebung. Il risultato è la rinuncia alle certezze della modernità: il Soggetto, la filosofia della storia, la celebrazione dei trionfi tecnoscientifici, in favore di una nozione «debole» del soggetto e del reale e di un rapporto con il passato, connotato come pietas, che lo vede più come un cumulo di rovine che come svolgimento delle sorti progressive dell’umanità. Ciò non significa però rinuncia alle istanze etico-politiche di emancipazione che Vattimo rivendica per il postmoderno fin dagli esordi del dibattito.

description: In models of the Universe with extra dimensions gravity propagates in the whole space-time. Graviton production by matter on the brane is significant in the early hot Universe. In a model of 3-brane with matter embedded in 5D space-time conditions for gravitons emitted from the brane to the bulk to return back to the brane are found. For a given 5-momentum of graviton falling back to the brane the interval between the times of emission and return to the brane is calculated. A method to calculate contribution to the energy-momentum tensor from multiple graviton bouncings is developed. Explicit expressions for contributions to the energy-momentum tensor of gravitons which have made one, two and three bounces are obtained and their magnitudes are numerically calculated. These expressions are used to solve the evolution equation for dark radiation. A relation connecting reheating temperature and the scale of extra dimension is obtained. For the reheating temperature $T_R\sim 10^6 GeV$ we estimate the scale of extra dimension $\m$ to be of order $10^{-9} GeV\,\,\, (\m^{-1}\sim 10^{-5} cm )$.

L'esperimento del nichilismo
Creators: name: Chiurazzi, Gaetano
Publisher: name: Trópos
Year: 2023

description: In un saggio contenuto in La fine della modernità, Vattimo pone quella che può essere considerata la pietra angolare della sua proposta filosofica, il nesso tra ermeneutica e nichilismo. Tale nesso viene teorizzato in rapporto al modo in cui, nel testo fondamentale dell’ermeneutica filosofica contemporanea, Verità e metodo di H.G. Gadamer (1960), veniva proposto il problema della verità, a partire dall’esperienza dell’arte: questa esperienza ha per Vattimo un peculiare accento nichilistico perché è un’esperienza di “sfondamento”, in cui si esperisce la perdita di cogenza e di continuità del proprio mondo, ovvero quella dimensione di storicità che pure in Gadamer accomuna esperienza artistica ed esperienza storica, ma che, secondo Vattimo, sarebbe pensata ancora in termini eccessivamente cumulativi e addirittura sostanzialistici (nel senso hegeliano del termine). In verità, questa dimensione nichilistica non è assente neanche nell’analisi gadameriana, che, ispirandosi al concetto hegeliano di Erfahrung, pone l’accento sul momento negativo che smobilita le certezze del soggetto e lo induce a un riassestamento della sua visione del mondo.

description: We compare the classification as entangled or separable of Bell diagonal bipartite qudits with positive partial transposition (PPT) and their properties for different dimensions. For dimension $d \geq 3$, a form of entanglement exists that is hard to detect and called bound entanglement due to the fact that such entangled states cannot be used for entanglement distillation. Up to this date, no efficient solution is known to differentiate bound entangled from separable states. We address and compare this problem named separability problem for a family of bipartite Bell diagonal qudits with special algebraic and geometric structures and applications in quantum information processing tasks in different dimensions. Extending analytical and numerical methods and results for Bell diagonal qutrits ($d=3$), we successfully classify more than $75\%$ of representative Bell diagonal PPT states for $d=4$. Via those representative states we are able to estimate the volumes of separable and bound entangled states among PPT ququarts ($d=4$). We find that at least $75.7\%$ of all PPT states are separable, $1.7\%$ bound entangled and for $22.6\%$ it remains unclear whether they are separable or bound entangled. Comparing the structure of bound entangled states and their detectors, we find considerable differences in the detection capabilities for different dimensions and relate those to differences of the Euclidean geometry for qutrits ($d=3$) and ququarts ($d=4$). Finally, using a detailed visual analysis of the set of separable and bound entangled Bell diagonal states in both dimensions, qualitative observations are made that allow to better distinguish bound entangled from separable states.

description: Objective: To examine the prevalence and predictors of patient-reported barriers to care among survivors of head and neck squamous cell carcinoma and the association with health-related quality of life (HRQOL) outcomes. Study Design: Retrospective cohort study. Setting: Outpatient oncology clinic at an academic tertiary care center. Methods: Data were obtained from the UNC Health Registry/Cancer Survivorship Cohort. Barriers to care included self-reported delays in care and inability to obtain needed care due to cost. HRQOL was measured with validated questionnaires: general (PROMIS) and cancer specific (FACT-GP). Results: The sample included 202 patients with head and neck squamous cell carcinoma with a mean age of 59.6 years (SD, 10.0). Eighty-two percent were male and 87% were White. Sixty-two patients (31%) reported at least 1 barrier to care. Significant predictors of a barrier to care in unadjusted analysis included age ≤60 years (P =.007), female sex (P =.020), being unmarried (P =.016), being uninsured (P =.047), and Medicaid insurance (P =.022). Patients reporting barriers to care had significantly worse physical and mental HRQOL on the PROMIS questionnaires (P <.001 and P =.002, respectively) and lower cancer-specific HRQOL on the FACT-GP questionnaire (P <.001), which persisted across physical, social, emotional, and functional domains. There was no difference in 5-year OS (75.3% vs 84.1%, P =.177) or 5-year CSS (81.6% vs 85.4%, P =.542) in patients with and without barriers to care. Conclusion: Delay- and affordability-related barriers are common among survivors of head and neck cancer and appear to be associated with significantly worse HRQOL outcomes. Certain sociodemographic groups appear to be more at risk of patient-reported barriers to care.

description: Un tema ricorrente, nelle interpretazioni che qui vengono raccolte intorno al pensiero di Gianni Vattimo, è da ritrovare nel richiamo alla pretesa del pensiero debole di non essere una semplice registrazione della pluralità dei mondi culturali e dei criteri di verità. Il pensiero debole non vuole essere una filosofia delle culture e una variazione sul tema dell’aggiornamento al tempo delle differenze. Quando la filosofia di Gianni Vattimo rileva nel mondo occidentale la trasformazione dell’essere delle cose nella loro rappresentazione, esso rileva anche che quanto si dà nel modo della rappresentazione è ancora l’essere stesso. Non si tratta quindi di una teoria della matura potenza dei me- dia e dei loro giochi di potere – si tratta piuttosto dell’indagine su come, nella rappresentazione della realtà, la realtà stessa continui a darsi e a presentarsi.

description: The MINiature Exoplanet Radial Velocity Array (MINERVA) is a US-based observational facility dedicated to the discovery and characterization of exoplanets around a nearby sample of bright stars. MINERVA employs a robotic array of four 0.7 m telescopes outfitted for both high-resolution spectroscopy and photometry, and is designed for completely autonomous operation. The primary science program is a dedicated radial velocity survey and the secondary science objective is to obtain high precision transit light curves. The modular design of the facility and the flexibility of our hardware allows for both science programs to be pursued simultaneously, while the robotic control software provides a robust and efficient means to carry out nightly observations. In this article, we describe the design of MINERVA including major hardware components, software, and science goals. The telescopes and photometry cameras are characterized at our test facility on the Caltech campus in Pasadena, CA, and their on-sky performance is validated. New observations from our test facility demonstrate sub-mmag photometric precision of one of our radial velocity survey targets, and we present new transit observations and fits of WASP-52b -- a known hot-Jupiter with an inflated radius and misaligned orbit. The facility is now in the process of being relocated to its final destination at the Fred Lawrence Whipple Observatory in southern Arizona, and science operations will begin in 2015.

description: Laboratory studies have observed chemopreventive effects of black and green tea on breast cancer development, but few epidemiologic studies have identified such effects. We investigated the association between tea consumption and breast cancer risk using data from 45,744 U.S. and Puerto Rican women participating in the Sister Study. Frequency and serving size of black and green tea consumption were measured at cohort enrollment. Breast cancer diagnoses were reported during follow-up and confirmed by medical record review. Multivariable Cox proportional hazards regression was used to estimate hazard ratios (HR) and 95% confidence intervals (CI). We further investigated potential variation according to estrogen receptor (ER) status, menopausal status and body mass index (BMI). Overall, 81.6 and 56.0% of women drank black or green tea, respectively. A total of 2,809 breast cancer cases were identified in the cohort. The multivariable model suggested an inverse association between black (≥5 vs. 0 cups/week: HR = 0.88, 95% CI 0.78, 1.00, p-trend = 0.08) and green tea (≥5 vs. 0 cups/week: HR = 0.82, 95% CI 0.70, 0.95, p-trend < 0.01) consumption and breast cancer risk. We did not observe differences by ER characteristics, menopausal status or BMI. In conclusion, our study suggests drinking at least five cups of green or black tea per week may be associated with decreased breast cancer risk.

description: We develop a novel formulation of the Performance Estimation Problem (PEP) for decentralized optimization whose size is independent of the number of agents in the network. The PEP approach allows computing automatically the worst-case performance and worst-case instance of first-order optimization methods by solving an SDP. Unlike previous work, the size of our new PEP formulation is independent of the network size. For this purpose, we take a global view of the decentralized problem and we also decouple the consensus subspace and its orthogonal complement. We apply our methodology to different decentralized methods such as DGD, DIGing and EXTRA and obtain numerically tight performance guarantees that are valid for any network size.
