description: Inflationary slow-roll dynamics in Einstein gravity with a non-minimal scalar-curvature coupling can be equivalent to that in the certain f(R) gravity theory. We review the correspondence and extend it to N=1 supergravity. The non-minimal coupling in supergravity is rewritten in terms of the standard (`minimal') N=1 matter-coupled supergravity by using curved superspace. The established equivalence between two different inflationary theories means the same inflaton scalar potential, and does not imply the same post-inflationary dynamics and reheating.

description: The effect of the complex phase of the fermion determinant is a key question related to the sign problem in finite-density QCD. Recently it has been shown that ignoring the complex phase -- the phase quenching -- does not change physics in a certain region of the phase diagram when a number of colors N_c is large. In this paper we study the effect of the phase quenching within the frameworks of effective models and holographic models. We show, in a unified manner, that the phase quenching gives exact results for any fermionic observables (e.g., chiral condensate) in the mean-field approximation and for gauge-invariant gluonic observables (e.g., Polyakov loop) to one-meson-loop corrections beyond mean field. We also discuss implications for the lattice simulations and confirm good quantitative agreement between our prediction and existing lattice QCD results. Therefore the phase quenching provides rather accurate answer already at N_c=3 with small 1/N_c corrections which can be taken into account by the phase reweighting.

description: Context A positive family history is a well defined risk factor for the development of pancreatic cancer. However, data is scarce regarding time of progression in these families and no clear guidelines are available about time interval and modality when to follow these individuals. Case report A 47-year-old male with two first-degree relatives dead of pancreatic cancer (mother 53 and sister 40 years, respectively). In 2007 at the age of 43, the patient was included into a screening program by annual CT scans at a community hospital. In 2009, after two years of negative screening, it was suggested to increase the interval to biannual CTs. At the beginning of 2011 the patient was admitted due to abdominal pain and jaundice. Imaging showed a 3 cm large tumor in the head of the pancreas with encasement of a replaced right hepatic artery from the superior mesenteric artery. The patient underwent total pancreatectomy with en block resection of the right hepatic artery, rebuilt by a rotation end-to-end anastomosis to the splenic artery. Histology showed pancreatic ductal adenocarcinoma (pT3, pN1, pM0). At 12-month follow up no recurrence has been detected. Conclusion A positive familial history is a risk factor to develop pancreatic cancer. In this family, as suggested by the EUROPAC, two first-degree affected, with a cumulative age at the diagnosis less than 110 years, is an important risk factor. The current case suggests that an annual screening seems reasonable and safer than longer intervals of time.

description: Context The median survival in resected pancreatic ductal adenocarcinoma (PDAC) is about two years. However, a considerable percentage of patients die within the first year after resection. Objective The aim of this study was to evaluate pre-operative factors predicting a short survival after pancreatico­duodenectomy (PD) for PDAC. Methods One hundred consecutive patients undergone PD for PDAC without in-hospital mortality from October 2006 to July 2010 were retrieved from our prospective database. The cohort was divided by survival into short term (≤12 months: group A) and long term (>12 months: group B) survivors and evaluated regarding pre-operative factors including age, weight loss, BMI, tumor size and proximity (no contact-contact) to the portal/mesenteric vein (PV/SMV). Results No significant differences were found between group A (n=27) and group B (n=73) regarding mean age (68±2 vs. 66±1 years; P=0.3), weight loss (87% vs. 85%; P=1.0), BMI (24±0.6 kg/m2 vs. 24±0.5 kg/m2; P=0.7) or adjuvant treatment. Group A had bigger tumors (35±2 mm vs. 29±1 mm; P=0.01) but no significant difference in proximity of the tumor to the PV/SMV (contact: A 67% vs. B 49%; P=0.2) or venous resections. Group A had more frequently pre-operative diabetes (33% vs. 9.6%; P=0.01) compared to group B. Conclusion Tumor size and pre-operative diabetes seems to be important negative prognostic factors for survival after PD for PDAC.

description: Context Pancreatic carcinoma still lacks specific markers. Earlier diagnosis could benefit many patients anticipating resection or other potential cures that today have palliative effects. In addition, differential diagnosis of suspect lesions obtained by imaging could spare resections of benign tumors. Here, we analyzed Gα15 as a potential diagnostic marker. Gα15 is an intracellular signaling protein that we previously found to be ectopically expressed in the pancreas upon transformation. Objective To establish a correlation between the presence of malignant cells in human pancreas and Gα15 mRNA expression in biopsies and in the blood. Methods Microarray studies available in Oncomine analyzing pancreatic cancer were selected; all data sets including human pancreatic cancer cases paired to adjacent healthy tissue were taken in consideration, for a total of 54 pairs of samples. Furthermore, free RNA was extracted from serum of patients affected by pancreatic cancer. First-strand cDNA was generated retrotranscribing with random hexamers. RT PCR was performed using TaqMan gene-specific primers and probe specific for Gα15 sequence. Results All three microarrays datasets, normalized to compare neoplastic to normal tissues, report Gα15 overexpression in neoplastic tissue with higher Gα15 mRNA levels in 49/54 patients. The presence of circulating Gα15 mRNA was assessed in the serum of 8 adenocarcinoma patients showing a significant increase over samples obtained from 8 healthy donors. Conclusions Gα15 mRNA appearance in neoplastic pancreas or in the blood stream should be explored to assess its potential as an indicator of the presence of malignant cells.

description: Unquestionable holders of aesthetic content, images have a well-known role even in conveying scientific knowledge. In the present work, we focus on the epistemological role of images within neuroscience. We first analyze the concepts of representation, similarity, and informativeness. Second, we discuss relevant case-studies, i.e., images by functional Magnetic Resonance Imaging, and how the pictorial interventions commonly applied on them might have an impact on their informational content. Finally, we explore the notion of imagination as a relevant faculty for modelling neuroscientific theories and the concept of creativity as an instrument to aesthetically modify brain images. These manipulations enable images to achieve the scientific purpose, altering the relation of similarity between the image and the studied phenomenon. In conclusion, this process leads to rethinking the role of the neuroscientist as an active observer.

On the limits of quantum theory: contextuality and the quantum-classical cut
Creators: name: Ellis, George F. R.
Publisher: name: arXiv
Year: 2011
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: This paper is based on four assumptions: 1. Physical reality is made of linearly behaving components combined in non-linear ways. 2. Higher level behaviour emerges from this lower level structure. 3. The way the lower level elements behaves depends on the context in which they are imbedded. 4. Quantum theory applies to the lower level entities. An implication is that higher level effective laws, based in the outcomes of non-linear combinations of lower level linear interactions, will generically not be unitary; hence the applicability of quantum theory at higher levels is strictly limited. This leads to the view that both state vector preparation and the quantum measurement process are crucially based in top-down causal effects, and helps provide criteria for the Heisenberg cut that challenge some views on Schroedinger's cat.

description: We study the complete phase space and the quench dynamics of an exactly solvable spin chain, the cluster-XY model. In this chain, the cluster term and the XY couplings compete to give a rich phase diagram. The phase diagram is studied by means of the quantum geometric tensor. We study the time evolution of the system after a critical quantum quench using the Loschmidt echo. The structure of the revivals after critical quantum quenches presents a non trivial behavior depending on the phase of the initial state and the critical point.

description: We study the two-dimensional Bose-Hubbard model in the presence of a three-body interaction term, both at a mean field level and via quantum Monte Carlo simulations. The three-body term is tuned by coupling the triply occupied states to a trapped universal trimer. We find that, for sufficiently attractive three-body interaction the n = 2 Mott lobe disappears and the system displays first order phase transitions separating the n = 1 from the n = 3 lobes, and the n = 1 and n = 3 Mott insulator from the superfluid. We have also analyzed the effect of finite temperature and found that transitions are still of first order at temperatures T\simJ where J is the hopping matrix element.

description: Highly immunocompromised pediatric and adult hematopoietic cell transplant (HCT) recipients frequently experience respiratory infections caused by viruses that are less virulent in immunocompetent individuals. Most of these infections, with the exception of rhinovirus as well as adenovirus and parainfluenza virus in tropical areas, are seasonal variable and occur before and after HCT. Infectious disease management includes sampling of respiratory specimens from nasopharyngeal washes or swabs as well as sputum and tracheal or tracheobronchial lavages. These are subjected to improved diagnostic tools including multiplex PCR assays that are routinely used allowing for expedient detection of all respiratory viruses. Disease progression along with high mortality is frequently associated with respiratory syncytial virus, parainfluenza virus, influenza virus, and metapneumovirus infections. In this review, we discuss clinical findings and the appropriate use of diagnostic measures. Additionally, we also discuss treatment options and suggest new drug formulations that might prove useful in treating respiratory viral infections. Finally, we shed light on the role of the state of immune reconstitution and on the use of immunosuppressive drugs on the outcome of infection.
Wittgenstein’s Bridge

description:

This paper uses structure-mapping to bridge the divide between the analytical and visual culture traditions of image interpretation. Wittgenstein’s analytic ‘picture theory of meaning’ from his early period, and his cultural theory of ‘meaning as use’ from his later period are used to show that the terms similarity, analogy and metaphor can be applied to both image and linguistic interpretation. As a result, by the mapping of similarity and analogy onto the analytic approach, and by the mapping of metaphor onto the visual culture approach, a common linguistic ground for the comparison of these two approaches to image interpretation can be established.

description: A well-known connection between n strings winding around a circle and permutations of n objects plays a fundamental role in the string theory of large N two dimensional Yang Mills theory and elsewhere in topological and physical string theories. Basic questions in the enumeration of Feynman graphs can be expressed elegantly in terms of permutation groups. We show that these permutation techniques for Feynman graph enumeration, along with the Burnside counting lemma, lead to equalities between counting problems of Feynman graphs in scalar field theories and Quantum Electrodynamics with the counting of amplitudes in a string theory with torus or cylinder target space. This string theory arises in the large N expansion of two dimensional Yang Mills and is closely related to lattice gauge theory with S_n gauge group. We collect and extend results on generating functions for Feynman graph counting, which connect directly with the string picture. We propose that the connection between string combinatorics and permutations has implications for QFT-string dualities, beyond the framework of large N gauge theory.

description: Context Steroids are effective to induce remission in autoimmune pancreatitis (AIP). Low dosages of steroids are currently used as maintenance treatment in Japan. Immunosuppressive drugs have been suggested for maintenance treatment but no studies have been published yet for indications and their efficacy. Objective To evaluate the indications and the efficacy of azathioprine (AZA) for the long-term treatment of AIP. Patients and Methods All non operated AIP patients observed from 2003 were retrospectively evaluated. We excluded patients where AZA was used for the associated autoimmune disease. We divided patients in those not treated (AZA-) and treated (AZA+) with AZA at dosage of 2 mg/kg/day. Clinical, radiological and biochemical data were compared in AZA- and AZA+ groups and before and after AZA treatment. Pancreatic enlargement was considered as relapse of AIP. Results Fifty-eight patients (39 M, 19 F; age at clinical onset 45.8±17.1 years) were evaluated: 41 in AZA- and 17 in AZA+ groups. Older age, jaundice at clinical onset, number of relapse, high serum levels of IgG4, other organ’s involvement were significantly more frequently observed in AZA+ compared to AZA-. In AZA+ group, relapse was observed in 16/17 (94%) before treatment and in 2/16 (12%) after treatment (mean follow-up 3 years; range 1-8 years). Both AZA+ relapsing patients were treated with steroids, continuing AZA, and fully responded to therapy. One patient discontinued AZA for side effects (hepatitis). Conclusion AZA seems to be an effective and safe treatment in AIP.

description: The recent discovery by the Daya-Bay and RENO experiments, that θ_{13} is nonzero and relatively large, significantly impacts existing experiments and the planning of future facilities. In many scenarios, the nonzero value of θ_{13} implies that θ_{23} is likely to be different from π/4. Additionally, large detectors will be sensitive to matter effects on the oscillations of atmospheric neutrinos, making it possible to determine the neutrino mass hierarchy and the octant of θ_{23}. We show that a 50 kT magnetized liquid argon neutrino detector can ascertain the mass hierarchy with a significance larger than 4 sigma with moderate exposure times, and the octant at the level of 2-3 sigma with greater exposure.

Rare-class classification using ensembles of subsets of variables
Creators: name: Tomal, Jabed H.
Publisher: name: University of British Columbia
Year: 2014

description: An ensemble of classifiers is proposed for predictive ranking of the observations in a dataset so that the rare class observations are found in the top of the ranked list. Four drug-discovery bioassay datasets, containing a few active and majority inactive chemical compounds, are used in this thesis. The compounds' activity status serves as the response variable while a set of descriptors, describing the structures of chemical compounds, serve as predictors. Five separate descriptor sets are used in each assay. The proposed ensemble aggregates over the descriptor sets by averaging probabilities of activity from random forests applied to the five descriptor sets. The resulting ensemble ensures better predictive ranking than the most accurate random forest applied to a single descriptor set. Motivated from the results of the ensemble of descriptor sets, an algorithm is developed to uncover data-adaptive subsets of variables (we call phalanxes) in a variable rich descriptor set. Capitalizing on the richness of variables, the algorithm looks for the sets of predictors that work well together in a classifier. The data-adaptive phalanxes are so formed that they help each other while forming an ensemble. The phalanxes are aggregated by averaging probabilities of activity from random forests applied to the phalanxes. The ensemble of phalanxes (EPX) outperforms random forests and regularized random forests in terms of predictive ranking. In general, EPX performs very well in a descriptor set with many variables, and in a bioassay containing a few active compounds. The phalanxes are also aggregated within and across the descriptor sets. In all of the four bioassays, the resulting ensemble outperforms the ensemble of descriptor sets, and random forests applied to the pool of the five descriptor sets. The ensemble of phalanxes is also adapted to a logistic regression model and applied to the protein homology dataset downloaded from the KDD Cup 2004 competition. The ensembles are applied to a real test set. The adapted version of the ensemble is found more powerful in terms of predictive ranking and less computationally demanding than the original ensemble of phalanxes with random forests.

description: Context A final diagnosis of benign lesions is reported in up to 21% of patients who underwent duodenocephalopancreatectomy for neoplasia, whereas no data have yet been published for resection of the body-tail. Objective To investigate the frequency and to characterize the benign lesions mimicking a neoplasia in the head and in the body-tail of the pancreas. Methods We retrospectively reviewed all the pancreatic specimens collected from 2005 to 2011 in the database of the Institute of Pathology of Mainz. Patients with a final diagnosis excluding malignancy were analyzed by histological, clinical and imaging findings. Results Three-hundreds and 73 patients were identified. A final diagnosis of benign disease was observed in 33 patients (8.8%), in 25 out of 298 (8.4%) in the resections of the pancreatic head and in 8 out of 75 (10.7%) of the body-tail. Among them we found paraduodenal pancreatitis (PP) in 13 cases (39.4%), autoimmune pancreatitis (AIP) in 11 (33.3%), chronic pancreatitis (CP) in 6 (18.2%) and accessory spleen in 3 (9.1%). In the head of the pancreas the most frequent diagnosis is PP and AIP, whereas in the body-tail accessory spleen and CP. Patients with benign lesions were more likely to be males, younger, smokers and drinkers, with longer lasting pain. Lower serum levels of CA 19-9 and lower frequency of jaundice were more frequently observed in this group. Pancreatic calcifications were more frequently associated with benign lesions whereas a larger dilation of common bile duct in the malignant lesions. AIP and PP have different clinical and radiological profiles. Conclusion Benign lesions are observed with the same frequency in specimens of the head or body-tail of the pancreas, while the type of final diagnosis is different.

description: The ALICE experiment at the LHC has studied J/psi production at mid-rapidity in pp collisions at sqrt{s}=7 TeV through its electron pair decay on a data sample corresponding to an integrated luminosity L_int = 5.6nb-1. The fraction of J/psi from the decay of long-lived beauty hadrons was determined for J/psi candidates with transverse momentum p_t>1.3 GeV/c and rapidity |y|<0.9. The cross section for prompt J/psi mesons, i.e. directly produced J/psi and prompt decays of heavier charmonium states such as the Psi(2S) and Csi_c resonances, is sigma_prompt-J/psi(pt > 1.3 GeV/c, |y| < 0.9) = 8.3 +- 0.8(stat.) +- 1.1(syst.) + 1.5 - 1.4(syst. pol.) micro barn. The cross section for the production of b-hadrons decaying to J/psi with p_t>1.3 GeV/c and |y|<0.9 is sigma_{J/psi

description: Context Paraduodenal pancreatitis (PP) is a form of chronic pancreatitis involving the duodenal wall close to the minor papilla within the surrounding parenchymal pancreatic tissue and common bile duct (the also called groove area). This disorder most commonly affects male patients in the 5th decade with a history of alcohol and/or smoke abuse. It has been postulated that alcohol or smoking leads to a resistance of the pancreatic juice flow and ischemia of the paraduodenal tissue. Objective To evaluate pancreatic specimens of a series of patients suffering from PP with special emphasis on vascular changes. Patients and Methods Twelve pancreatic specimens of patients with a definitive diagnosis of PP (all males, mean age 44.4 years) were evaluated. Most of them presented with abdominal pain (n=10) and weight loss (n=8). All patients were smokers and alcohol abuse was documented in 8 patients. For histological evaluation, tissue specimens were routinely processed. Results The following histological characteristics were observed: Brunner’s gland hyperplasia, cystic changes and adenomyomatosis of the duodenal wall were also found in 11 patients. Variable numbers of a mixed inflammatory infiltrate were present in all patients analyzed. In 6 patients, we found foreign body giant cell reaction in the neighbourhood of some pseudocysts. However, most interestingly obliteration of segmental arteries was present in 7/12 cases. Conclusion This histological study confirms the common morphological changes in paraduodenal pancreatitis. Interestingly, we found vessel obliteration in several cases, which has not been described for this subtype of chronic pancreatitis so far. It remains to be investigated whether this finding is specific for PP, might reflect a particular subgroup of paraduodenal pancreatitis or might be a marker of disease progression.

The Visual Power of Photography and Its Status as a Representation
Creators: name: Weichert, Katarzyna
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2021

description:

I shall introduce a hermeneutic perspective and photography analyses from visual theory to the debate concerning the status of photographic representation (together with film, as it is based on the photographic method) which continues within Anglo-Saxon aesthetics and analytical aesthetics. I mostly confront Roger Scruton and Gregory Currie’s thoughts on the photograph and its object (source), representation-by-origin and representation-by-use with Gottfried Boehm’s concept of aesthetic nondifferentiation, and Georges Didi-Huberman’s analyses of photographs. This shall allow me to identify the two aspects of photography (independence of an individual object and visual dynamics of an image) which have a significant impact on the status of photography as a representation and on the potential of cinematographic creation as a story told through images.

The Productive Inadequacy of Image for Contemporary Painting
Creators: name: Derby, Moyra
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2021

description:

This article considers the productive inadequacy of image for contemporary painting. The mutability of image is tested against the material, spatial and durational conditions of painting, and the attentional attachments it might mobilize through an examination of the working methods of Beth Harland, Jacqueline Humphries and R.H.Quaytman. Painting is not positioned as image, but as a processor of image information, able to prompt an image response, A resistance to image is framed by the art historical and philosophical legacy of image expectations and preclusions that each artist feels compelled to work against, and the expanding opticality of our contemporary social, cultural and economic interactions.

description: ABC-stacked trilayer graphene's chiral band structure results in three ($n=0,1,2$) Landau level orbitals with zero kinetic energy. This unique feature has important consequences on the interaction driven states of the 12-fold degenerate (including spin and valley) N=0 Landau level. In particular, at many filling factors $ν_{T} =\pm5,\pm4,\pm2,\pm1$ a quantum phase transition from a quantum Hall liquid state to a triangular charge density wave occurs as a function of the single-particle induced LL orbital splitting $Δ_{LL}$. This phase transition should be characterized by a re-entrant integer quantum Hall effect with the Hall conductivity corresponding to the {\it adjacent} interaction driven integer quantum Hall plateau.

description: We present results from compressible Cartesian convection simulations with and without imposed shear. In the former case the dynamo is expected to be of $α^2\varOmega$ type which is generally expected to be relevant for the Sun, whereas the latter case refers to $α^2$ dynamos which are more likely to occur in more rapidly rotating stars whose differential rotation is small. We perform a parameter study where the shear flow and the rotational influence are varied to probe the relative importance of both types of dynamos. Oscillatory solutions are preferred both in the kinematic and saturated regimes when the negative ratio of shear to rotation rates, $q\equiv -S/\varOmega$, is between 1.5 and 2, i.e., when shear and rotation are of comparable strengths. Other regions of oscillatory solutions are found with small values of $q$, i.e., when shear is weak in comparison to rotation, and in the regime of large negative $q$s, when shear is very strong in comparison to rotation. However, exceptions to these rules also appear so that for a given ratio of shear to rotation, solutions are non-oscillatory for small and large shear, but oscillatory in the intermediate range. Changing the boundary conditions from vertical field to perfect conductor ones changes the dynamo mode from oscillatory to quasi-steady. Furthermore, in many cases an oscillatory solution exists only in the kinematic regime whereas in the nonlinear stage the mean fields are stationary. However, the cases with rotation and no shear are always oscillatory in the parameter range studied here and the dynamo mode does not depend on the magnetic boundary conditions. The strengths of total and large-scale components of the magnetic field in the saturated state, however, are sensitive to the chosen boundary conditions.

The Narrative Aesthetics of Protest Images
Creators: name: Fasnacht, Hannah
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2021

description:

In this paper I argue that protest images have a certain aesthetics and a degree of transformative power. Crucial to this aesthetics is the images’ narrative structure, like the representation of goal-directed actions. On this basis, I show that there are more aspects that contribute to the storytelling capacity, like narrative characteristics and an aesthetics of dramatization. Using the example of climate change protests as a case study, I establish that these aspects can contribute to the transformative ability of protest images, if used effectively.

description: Context Overwhelming post-splenectomy sepsis (OPSI) is defined as septicemia and/or meningitis, usually fulminant, occurring days to several years after removal of the spleen. The risk of OPSI is estimated to be 0.23-0.42% per year with a lifetime risk of 5%. The highest risk of developing OPSI is within the first few years after splenectomy, particularly in children younger than 2 years and elderly patients. The incidence of sepsis is also associated with the underlying disease, with higher incidence for patients splenectomized for hematologic disease rather than for trauma. We report a case of a fulminant pneumococcal sepsis with a fatal outcome, occurring 11 years after distal pancreatectomy and splenectomy for pancreatic adenocarcinoma. Case report A 58-year-old woman presented to the emergency room in December 2011 with a 2-day history of mild fever and diarrhea, followed by hypotension, dyspnea, and peripheral cyanosis. Past medical history revealed a left breast quadrantectomy for lobular carcinoma (pT1N1M0G2) and distal pancreatectomy with splenectomy for ductal pancreatic adenocarcinoma (pT3N1M0G2) in October 2000. The patient was not aware of the need for prophylactic antibiotics and vaccination. Two years after surgery, she underwent excision of paraaortic lymph node, site of pancreatic cancer recurrence. Adjuvant therapy and oncological follow-up was planned. At admission, blood tests revealed abnormal coagulation screen, abnormal liver and kidney function, and metabolic acidosis. Despite the administration of intravenous fluid, vasopressor agents, antibiotics and mechanical ventilatory support, the patient died for multiorgan failure 7 hours after admission in intensive care unit. Blood culture showed the growth of Streotococcus Pneumoniae. Necropsy showed multiorgan failure with adrenal necrotic hemorrhage due to pneumococcal septicemia. No recurrence of pancreatic cancer was noted. Conclusions Although rare, OPSI is a well-known fatal complication which can occur to asplenic patients. The role of vaccination and antibiotics in preventing such complication is well-defined, but cases of fatal post-splenectomy sepsis are still reporting, also in vaccinated patients. There is a need of practical guidelines for patients and physicians, and a high index of suspicion must be maintained for any febrile illness in asplenic patients.

description: The purpose of this article is a set-indexed extension of the well-known Ornstein-Uhlenbeck process. The first part is devoted to a stationary definition of the random field and ends up with the proof of a complete characterization by its $L^2$-continuity, stationarity and set-indexed Markov properties. This specific Markov transition system allows to define a general \emph{set-indexed Ornstein-Uhlenbeck (SIOU) process} with any initial probability measure. Finally, in the multiparameter case, the SIOU process is proved to admit a natural integral representation.

Top Quark Forward-Backward Asymmetry and $W'$-Boson with General Couplings

description: The measured forward-backward asymmetry in top pair events at the Fermilab Tevatron collider deviates significantly from the standard model expectation. Several models have been proposed to describe the observed asymmetry which grows with the rapidity difference of the top pairs and also with the $t\bar{t}$ invariant mass. The presence of a heavy charged gauge boson $W'$ with the coupling $W'-t-d$ (left-handed, right-handed, and a mixture of left and right-handed couplings) could generate the desired top forward-backward asymmetry keeping the top pair cross section consistent with the standard model prediction. Such $W'$-boson makes contribution to the electric dipole moment of the neutron through contribution to the $d$-quark electric dipole moment, recently measured charge asymmetry ($A_{C}$) by the LHC experiments, and the total cross section of top pair at the LHC and Tevatron. We show that the upper bounds on neutron and top electric dipole moments disfavour any $W'$ with a mass below 240 GeV which could explain the Tevatron forward-backward asymmetry. It is shown that the charge asymmetry provides an allowed region in the parameters space with no overlap with the allowed region where the asymmetry could be described.

description: Context KRAS is an oncogene frequently mutated in pancreatic carcinomas. 90% of the mutations are localized at the level of codons 12, 13 and 61. Detecting a KRAS mutation could help to distinguish pancreatic cancer from pseudotumoral chronic pancreatitis. Identifying such mutations in preoperative endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) material is an important diagnostic aid. For this reason it is necessary to have highly sensitive and specific molecular techniques. Patients and Methods In 60 consecutive patients, who underwent EUS-FNA for typing of focal lesions of the pancreas, FNA material was processed for routine cytological analysis and an aliquot collected in ethanol for KRAS analysis. The material was used for the analysis of KRAS through: Sanger sequencing (Beckman CEQ2000 platform), Allele specific LNA qPCR (ASLNAqPCR) e Roche 454 GS-Junior sequencer (Next Generation Sequencing; NGS). Results At microscopic examination the cytological diagnosis ranged from malignant to non-neoplastic lesions. The analysis with the Sanger sequencing revealed KRAS mutations in 17/60 samples, using ASLNAqPCR KRAS mutations were detected in 25/60 patients while NGS allowed to detect mutations in 30/60 samples. With regard to cases with cytological diagnosis of primary adenocarcinoma, Sanger sequencing showed KRAS mutations in 6/15 (40%) cases, ASLNAqPCR in 10/15 (66.7%) and NGS in 12/15 (80%). Conclusions ASLNAqPCR and NGS techniques were found to be more sensitive than Sanger sequencing. The NGS allows to detect infrequent mutations and ASLNAqPCR provides data on the fraction of mutated cells in the analyzed sample. The use of one of these two techniques (or both of them) allows to characterize in a very precise way the KRAS molecular status of a pancreatic lesion starting from material obtained with EUS-FNA.
