description: Axion-like dark matter whose symmetry breaking occurs after the end of inflation predicts enhanced primordial density fluctuations at small scales. This leads to dense axion minihalos (or miniclusters) forming early in the history of the Universe. Condensation of axions in the minihalos leads to the formation and subsequent growth of axion stars at the cores of these halos. If, like the QCD axion, the axion-like particle has attractive self-interactions there is a maximal mass for these stars, above which the star rapidly shrinks and converts an $\mathcal{O}(1)$ fraction of its mass into unbound relativistic axions. This process would leave a similar (although in principle distinct) signature in cosmological observables as a decaying dark matter fraction, and thus is strongly constrained. We place new limits on the properties of axion-like particles that are independent of their non-gravitational couplings to the standard model.

description: Context When ERCP fails in the setting of combined biliary and duodenal obstruction, EUS-guided biliary drainage has emerged as an alternate method of biliary decompression. Case report We present a case of a 40-year-old man with advanced pancreatic cancer and a pre-existing duodenal wall stent who subsequently develops jaundice due to biliary obstruction. An ERCP was technically unsuccessful as the papilla was inaccessible despite probing within the duodenal stent. Transduodenal biliary drainage was achieved using EUS guidance to create a choledochoduodenostomy tract. A fully covered metal biliary stent was then deployed through the mesh of the duodenal wall stent. The patient’s jaundice and pruritus subsequently resolved. Conclusion This is the first report of successful transduodenal EUS-guided biliary drainage performed through an existing enteral wall stent and can still be considered as an alternate mode of biliary drainage in this setting.

description: We perform the first simultaneous extraction of parton collinear and transverse degrees of freedom from low-energy fixed-target Drell-Yan data in order to compare the transverse momentum dependent (TMD) parton distribution functions (PDFs) of the pion and proton. We demonstrate that the transverse separation of the quark field encoded in TMDs of the pion is more than $4 σ$ smaller than that of the proton. Additionally, we find the transverse separation of the quark field decreases as its longitudinal momentum fraction decreases. In studying the nuclear modification of TMDs, we find clear evidence for a transverse EMC effect. We comment on possible explanations for these intriguing behaviors, which call for a deeper examination of tomography in a variety of strongly interacting quark-gluon systems.

description: As a method beyond the mean-field analysis, a matrix product state (MPS) with incommensurate periodicity is applied to detect phase transitions accompanied with periodicity change, where the incommensurate MPS is generated by acting local-spin-rotation operators with the incommensurate periodicity on a uniform MPS. As a commensurate/commensurate change, we calculate the partial ferro -- perfect ferro phase transition in the $S=1/2$ Heisenberg model and its critical exponent of the magnetization curve. As a commensurate/incommensurate change, we calculate the S=1 Heisenberg model with bilinear and biquadratic interactions which has periodicity change in the spin-spin correlation function.

description: Context Heterotopic pancreas is defined as the presence of pancreatic tissue, outside its usual location, which lacks anatomical and vascular continuity with the pancreas proper. Despite the development of modern diagnostic procedures, it is still difficult to differentiate heterotopic pancreas from benign or malignant tumors and other tumor-like lesions. Frozen examination of mucinous lesions arising from heterotopic pancreas may represent a diagnostic problem. A decision may be very difficult and it is sometimes impossible to decide on the basis of the frozen sections whether a lesion is benign or malignant. Case report We report a tumor-like lesion mimicking a mucinous (colloid) carcinoma arising in heterotopic pancreatic tissue in the prepyloric antrum of a 56-year-old woman which was found incidentally during an elective laparoscopic cholecystectomy for cholelithiasis. The tumor was treated by wedge resection and, in the frozen section examination, there were pancreatic ducts in the proper muscle layer, pancreatic acini with islets of Langerhans under the serosal surface and mucinous lakes close to the heterotopic pancreatic tissue and to a peripheral nerve. Conclusion The significance of this unusual lesion is its potential confusion with mucinous (colloid) carcinoma or other mucous tumors. Such confusion is more likely to occur if the tissue sample is selective or limited, and the presence of pancreatic tissue cannot be verified. Therefore, we believe that a choice of local excision, wedge resection or more extensive eradication be determined only after intraoperative, pathological confirmation of the complete and accurate diagnosis.

description: Context Extragastrointestinal stromal tumors arising in the pancreas are extremely rare. To date, only eight cases have been reported in the literature. Case report A 42-year-old female patient presented with gradually increasing abdominal pain of 6-month duration. Computerized tomography scan of the abdomen demonstrated a solid cystic mass in the body and tail of the pancreas. En-block R0 resection of the mass with distal pancreatectomy, splenectomy and left hemicolectomy was carried out following a radiological diagnosis of a malignant cystic neoplasm of the pancreas. Histopathological and immunohistochemical findings of the lesion were consistent with a gastrointestinal stromal tumor. Conclusion Extragastrointestinal stromal tumor of the pancreas, though rare, should be considered in the differential diagnosis of the more common cystic lesions at this site.

description: Context "Low-risk" branch duct intraductal papillary mucinous neoplasm (IPMN) is defined as pancreatic epithelial cellular proliferation of small branch ducts that lack malignant characteristics. At present, our understanding of the natural history of "low-risk" branch duct IPMN is still evolving. Lady Windermere syndrome is a disorder seen in non-smoking women with no pre-existing pulmonary disease affecting the lingula and/or right middle lobe with Mycobacterium avium-intracellulare complex. We present a case with pancreatic adenocarcinoma after a six-year surveillance of "low-risk" branch duct IPMN in an asymptomatic elderly white woman with Lady Windermere syndrome. Case report A 79-year-old woman was referred to our institution because of pancreatic cystic abnormalities and elevated carbohydrate antigen 19-9 (CA 19-9). While at our institution, she was also diagnosed with Lady Windermere syndrome. Multiple abdominal imaging studies, endoscopic retrograde cholangiopancreatography, computer tomography, and magnetic resonance cholangiopancreatography (MRCP) were performed in the ensuing 6 years, all consistent with "low-risk" branch duct IPMN. No progression was seen until year 6 when MRCP showed a 2 cm pancreatic cancer. Because of multiple comorbidities, the patient chose chemotherapy over a pancreaticoduodenectomy. She developed respiratory failure and died after one cycle of gemcitabine. Conclusions "Low-risk" branch duct IPMN may be a heterogeneous disease in which some cases can transform into malignant pancreatic neoplasms despite the absence of the so-called "high risk" features on imaging studies. Clinical management, therefore, requires individualized flexibility. In addition, when there is coexistence of Lady Windermere syndrome and pancreatic cancer, prompt diagnosis and treatment of Lady Windermere syndrome should be considered prior to chemoradiotherapy or surgery.

description: We propose and study a generalization of Kitaev's $\mathbb Z_2$ toric code on a square lattice with an additional global $U(1)$ symmetry. Using Quantum Monte Carlo simulation, we find strong evidence for a topologically ordered ground state manifold with indications of UV/IR mixing, i.e., the topological degeneracy of the ground state depends on the microscopic details of the lattice. Specifically, the ground state degeneracy depends on the lattice tilt relative to the directions of the torus cycles. In particular, we observe that while the usual compactification along the vertical/horizontal lines of the square lattice shows a two-fold ground state degeneracy, compactifying the lattice at $45^\circ$ leads to a three-fold degeneracy. In addition to its unusual topological properties, this system also exhibits Hilbert space fragmentation. Finally, we propose a candidate experimental realization of the model in an array of superconducting quantum wires.

description: In a recent work [Proc. Natl. Acad. Sci. USA 108, 3838 (2011)], the authors proposed a simple measure for network robustness under malicious attacks on nodes. With a greedy algorithm, they found the optimal structure with respect to this quantity is an onion structure in which high-degree nodes form a core surrounded by rings of nodes with decreasing degree. However, in real networks the failure can also occur in links such as dysfunctional power cables and blocked airlines. Accordingly, complementary to the node-robustness measurement ($R_{n}$), we propose a link-robustness index ($R_{l}$). We show that solely enhancing $R_{n}$ cannot guarantee the improvement of $R_{l}$. Moreover, the structure of $R_{l}$-optimized network is found to be entirely different from that of onion network. In order to design robust networks resistant to more realistic attack condition, we propose a hybrid greedy algorithm which takes both the $R_{n}$ and $R_{l}$ into account. We validate the robustness of our generated networks against malicious attacks mixed with both nodes and links failure. Finally, some economical constraints for swapping the links in real networks are considered and significant improvement in both aspects of robustness are still achieved.

description: A nonlocal nonlinear Schrödinger equation with focusing nonlinearity is considered which has been derived as a continuum limit of the Calogero-Sutherland model in an integrable classical dynamical system. The equation is shown to stem from the compatibility conditions of a system of linear PDEs, assuring its complete integrability. We construct a nonsingular $N$-phase solution ($N$: positive integer) of the equation by means of a direct method. The features of the one- and two-phase solutions are investigated in comparison with the corresponding solutions of the defocusing version of the equation. We also provide an alternative representation of the $N$-phase solution in terms of solutions of a system of nonlinear algebraic equations. Furthermore, the eigenvalue problem associated with the $N$-phase solution is discussed briefly with some exact results. Subsequently, we demonstrate that the $N$-soliton solution can be obtained simply by taking the long-wave limit of the $N$-phase solution. The similar limiting procedure gives an alternative representation of the $N$-soliton solution as well as the exact results related to the corresponding eigenvalue problem.

description: Context Heterotopic pancreas is the presence of pancreatic tissue found outside the usual anatomical location of the pancreas. It is a rare condition and can occur anywhere in the gastrointestinal tract with the stomach and the small bowel being the most common sites. It is usually asymptomatic and often discovered incidentally. Case report We report the case of a 48-year-old Omani female who presented with recurrent epigastric pain. Endoscopy revealed a sessile mass in the antrum which was snared and showed heterotopic pancreatic tissue in the submucosa on histopathology. Conclusion Heterotopic pancreas should be considered in the differential diagnosis of gastric mass lesions.

description: La presente participación analiza la casa de alquiler llamada Casa Batlló de Antoni Gaudí y la posición excepcional de la arquitectura dentro de su obra. Mediante del ejemplo que aquí se presenta se trata de mostrar como Gaudí rompe con el arte de construcción de casas habitación urbanas común y crea una interrelación fenomenal entre el espacio exterior y el espacio interior, con lo cual adapta su construcción al entorno urbano y natural, abriéndose a éste. Lo urbano y lo natural penetran su arquitectura, de igual manera que su casa de alquiler se abre espacio en su entorno, pareciendo fusionarse con éste. Un enfoque especial del trabajo está por una parte en el diseño del piano nobile con su frente de ventanales y saledizos, que puede ser interpretado como un entrelazamiento de arquitectura y vida urbana, por otra parte se analizan de manera más detallada el diseño de la fachada y el patio de luces de la Casa Batlló, que ubican la construcción en el ambiente geográfico e histórico, y lo vinculan con su entorno natural.

description: We have analyzed solar-like oscillations in ~1700 stars observed by the Kepler Mission, spanning from the main-sequence to the red clump. Using evolutionary models, we test asteroseismic scaling relations for the frequency of maximum power (nu_max), the large frequency separation (Delta_nu) and oscillation amplitudes. We show that the difference of the Delta_nu-nu_max relation for unevolved and evolved stars can be explained by different distributions in effective temperature and stellar mass, in agreement with what is expected from scaling relations. For oscillation amplitudes, we show that neither (L/M)^s scaling nor the revised scaling relation by Kjeldsen & Bedding (2011) are accurate for red-giant stars, and demonstrate that a revised scaling relation with a separate luminosity-mass dependence can be used to calculate amplitudes from the main-sequence to red-giants to a precision of ~25%. The residuals show an offset particularly for unevolved stars, suggesting that an additional physical dependency is necessary to fully reproduce the observed amplitudes. We investigate correlations between amplitudes and stellar activity, and find evidence that the effect of amplitude suppression is most pronounced for subgiant stars. Finally, we test the location of the cool edge of the instability strip in the Hertzsprung-Russell diagram using solar-like oscillations and find the detections in the hottest stars compatible with a domain of hybrid stochastically excited and opacity driven pulsation.

description: Context Total pancreatectomy is the treatment of choice for multicentric diseases involving the head and the body-tail of the pancreas. Middle-preserving pancreatectomy is a recently reported alternative procedure when the pancreatic body is spared from disease. We report on the successful preservation of the pancreatic body in a patient harboring a multicentric intraductal papillary mucinous neoplasia (IPMN). Case report A multicentric IPMN was diagnosed in a 59-year-old man. A standard pylorus preserving pancreaticoduodenectomy was performed, followed by a spleen-preserving distal pancreatectomy. The splenic vessels were carefully preserved. The residual 5 cm of the pancreatic body were anastomosed to the jejunum after verifying that the resection line on both sides was negative at frozen section examination. The postoperative course was complicated by transient peritoneal bleeding managed with angiographic embolization of the splenic artery. A borderline mixed type IPMN of the head and chronic pancreatitis of the tail were found at pathological examination. Eleven months after surgery, the patient is well and disease free; glycemic control is achieved by diet. Conclusion A middle-preserving pancreatectomy can be performed safely for multicentric IPMNs involving the head and the body-tail of the gland. It can prevent problems with the glycemic control that usually follows total pancreatectomy.

description: We study the question of how visual analysis can support the comparison of spatio-temporal ensemble data of liquid and gas flow in porous media. To this end, we focus on a case study, in which nine different research groups concurrently simulated the process of injecting CO2 into the subsurface. We explore different data aggregation and interactive visualization approaches to compare and analyze these nine simulations. In terms of data aggregation, one key component is the choice of similarity metrics that define the relation between the different simulations. We test different metrics and find that a fine-tuned machine-learning based metric provides the best visualization results. Based on that, we propose different visualization methods. For overviewing the data, we use dimensionality reduction methods that allow us to plot and compare the different simulations in a scatterplot. To show details about the spatio-temporal data of each individual simulation, we employ a space-time cube volume rendering. We use the resulting interactive, multi-view visual analysis tool to explore the nine simulations and also to compare them to data from experimental setups. Our main findings include new insights into ranking of simulation results with respect to experimental data, and the development of gravity fingers in simulations.

description: We present the most extensive combined photometric and spectroscopic study to date of the enormous globular cluster (GC) system around M87, the central giant elliptical galaxy in the nearby Virgo cluster. Using observations from DEIMOS and LRIS at Keck, and Hectospec on the MMT, we derive new, precise radial velocities for 451 GCs around M87, with projected radii from ~ 5 to 185 kpc. We combine these measurements with literature data for a total sample of 737 objects, which we use for a re-examination of the kinematics of the GC system of M87. The velocities are analyzed in the context of archival wide-field photometry and a novel Hubble Space Telescope catalog of half-light radii, which includes sizes for 344 spectroscopically confirmed clusters. We use this unique catalog to identify 18 new candidate ultra-compact dwarfs, and to help clarify the relationship between these objects and true GCs. We find much lower values for the outer velocity dispersion and rotation of the GC system than in earlier papers, and also differ from previous work in seeing no evidence for a transition in the inner halo to a potential dominated by the Virgo cluster, nor for a truncation of the stellar halo. We find little kinematical evidence for an intergalactic GC population. Aided by the precision of the new velocity measurements, we see significant evidence for kinematical substructure over a wide range of radii, indicating that M87 is in active assembly. A simple, scale-free analysis finds less dark matter within ~85 kpc than in other recent work, reducing the tension between X-ray and optical results. In general, out to a projected radius of ~ 150 kpc, our data are consistent with the notion that M87 is not dynamically coupled to the Virgo cluster; the core of Virgo may be in the earliest stages of assembly.

We also provide good estimations for the Gorenstein global dimension of $RG$ in terms of this dimension and the Gorenstein global dimension of $R$. Moreover, we study special cases of groups, such as $\textsc{\textbf{lh}}\mathfrak{F}$-groups, and show that for such a group every Gorenstein projective $RG$-module is Gorenstein flat when the global dimension of $R$ is finite.

This was associated with abdominal distension, vomiting and melena. Laboratory investigations showed elevated serum amylase, coagulopathy and severe anemia. Computed tomography imaging showed a jejunal hematoma and pancreatitis with peripancreatic inflammation. She responded to conservative treatment in addition to correction of the coagulopathy and a blood transfusion. Her symptoms were resolved within a few days and a repeat computed tomography scan two months later showed complete resolution of the hematoma and the pancreatitis. Conclusion Our case demonstrates a rare complication of acute pancreatitis in a patient with risk factors.

description: Context Dieulafoy’s lesion is an unusual cause of gastrointestinal bleeding with the most common location being the stomach. A periampullary location is rare for a bleeding Dieulafoy’s lesion. Case report We present the case of a 52-year-old female who presented with intermittent painless melena. Her upper gastrointestinal endoscopy and colonoscopy were normal. She was a diagnostic challenge as no definite lesion could be identified on capsule endoscopy. However, as there was presence of fresh blood in the proximal jejunum, a push enteroscopy was performed which revealed the presence of fresh blood in the duodenum and proximal jejunum. But no bleeding lesion could be identified. A side view endoscopy was performed which revealed a bleeding periampullary Dieulafoy’s lesion. Immediate hemostasis was achieved with an injection of adrenalin. Other episodes of bleeding occurred and the patient was finally treated surgically. Conclusion A periampullary Dieulafoy’s lesion presenting with obscure gastrointestinal bleed is a diagnostic challenge and can be missed on capsule endoscopy.

description: Context Von Hippel-Lindau disease is an inherited syndrome of multiorgan neoplasia caused by a germline mutation in the von Hippel-Lindau gene and can include central nervous system tumors, renal cell carcinomas and benign pancreatic cystic tumors. Case report We report the case of a 56-year-old patient who had a past history of cerebellar hemangioblastoma and presented with abdominal pain. Imaging revealed renal tumors and multiple pancreatic tumors which caused duodenal and pancreatic duct compression. The patient was treated with a combination of radical right nephrectomy, total pancreaticoduodenectomy and splenectomy. Pathology identified a multifocal unilateral clear cell renal carcinoma which interestingly coexisted with multiple large pancreatic serous microcystic adenomas with infiltration of the fibrous capsule. Conclusion In past cases of von Hippel-Lindau disease, pancreatic adenomas with malignant transformation have not been reported. In our case, the infiltration of the fibrous capsule by parenchymal cells may indicate malignant transformation.

Quantum walk state transfer on a hypercube

description: We investigate state transfer on a hypercube by means of a quantum walk where the sender and the receiver vertices are marked by a weighted loops. First, we analyze search for a single marked vertex, which can be used for state transfer between arbitrary vertices by switching the weighted loop from the sender to the receiver after one run-time. Next, state transfer between antipodal vertices is considered. We show that one can tune the weight of the loop to achieve state transfer with high fidelity in shorter run-time in comparison to the state transfer with a switch. Finally, we investigate state transfer between vertices of arbitrary distance. It is shown that when the distance between the sender and the receiver is at least 2, the results derived for the antipodes are well applicable. If the sender and the receiver are direct neighbours the evolution follows a slightly different course. Nevertheless, state transfer with high fidelity is achieved in the same run-time.

Measurement of the non-prompt D-meson fraction as a function of multiplicity in proton$-$proton collisions at $\sqrt{s} = 13$ TeV

description: The fractions of non-prompt (i.e. originating from beauty-hadron decays) D$^0$ and D$^+$ mesons with respect to the inclusive yield are measured as a function of the charged-particle multiplicity in proton$-$proton collisions at a centre-of-mass energy of $\sqrt{s} = 13$ TeV with the ALICE detector at the LHC. The results are reported in intervals of transverse momentum ($p_{\rm T}$) and integrated in the range $1 < p_{\rm T} < 24$ GeV/$c$. The fraction of non-prompt D$^0$ and D$^+$ mesons is found to increase slightly as a function of $p_{\rm T}$ in all the measured multiplicity intervals, while no significant dependence on the charged-particle multiplicity is observed. In order to investigate the production and hadronisation mechanisms of charm and beauty quarks, the results are compared to PYTHIA 8 as well as EPOS 3 and EPOS 4 Monte Carlo simulations, and to calculations based on the colour glass condensate including three-pomeron fusion.

description: Is it possible, in principle, to measure the sign of the Lapse? We show that fermion dynamics distinguishes spacetimes having the same metric but different tetrads, for instance a Lapse with opposite sign. This sign might be a physical quantity not captured by the metric. We discuss its possible role in quantum gravity.

Year: 2011
Subjects: subject: Optics (physics.optics)
subject: FOS: Physical sciences

description: Propagation of ultrashort optical pulses in a dense resonant medium is considered in the semiclassical limit. In our analysis, we place emphasis on several main points. First, we study transformations of spectra in the process of pulse propagation and interactions with another pulse. The second point involves the transient processes (including pulse compression) connected with self-induced transparency soliton formation inside the medium. Finally, the third aspect is the study of collisions of co- and counter-propagating pulses in the medium. In the last case, the investigation of symmetric and asymmetric collisions shows the possibility of effectively controlling the parameters of transmitted radiation.

description: This paper presents a new type of evolutionary algorithm (EA) based on the concept of "meme", where the individuals forming the population are represented by semantic networks and the fitness measure is defined as a function of the represented knowledge. Our work can be classified as a novel memetic algorithm (MA), given that (1) it is the units of culture, or information, that are undergoing variation, transmission, and selection, very close to the original sense of memetics as it was introduced by Dawkins; and (2) this is different from existing MA, where the idea of memetics has been utilized as a means of local refinement by individual learning after classical global sampling of EA. The individual pieces of information are represented as simple semantic networks that are directed graphs of concepts and binary relations, going through variation by memetic versions of operators such as crossover and mutation, which utilize knowledge from commonsense knowledge bases. In evaluating this introductory work, as an interesting fitness measure, we focus on using the structure mapping theory of analogical reasoning from psychology to evolve pieces of information that are analogous to a given base information. Considering other possible fitness measures, the proposed representation and algorithm can serve as a computational tool for modeling memetic theories of knowledge, such as evolutionary epistemology and cultural selection theory.
