description: We introduce the framework of path-complete graph Lyapunov functions for approximation of the joint spectral radius. The approach is based on the analysis of the underlying switched system via inequalities imposed among multiple Lyapunov functions associated to a labeled directed graph. Inspired by concepts in automata theory and symbolic dynamics, we define a class of graphs called path-complete graphs, and show that any such graph gives rise to a method for proving stability of the switched system. This enables us to derive several asymptotically tight hierarchies of semidefinite programming relaxations that unify and generalize many existing techniques such as common quadratic, common sum of squares, and maximum/minimum-of-quadratics Lyapunov functions. We compare the quality of approximation obtained by certain classes of path-complete graphs including a family of dual graphs and all path-complete graphs with two nodes on an alphabet of two matrices. We provide approximation guarantees for several families of path-complete graphs, such as the De Bruijn graphs, establishing as a byproduct a constructive converse Lyapunov theorem for maximum/minimum-of-quadratics Lyapunov functions.

description: This paper describes a forward algorithm and an adjoint algorithm for computing sensitivity derivatives in chaotic dynamical systems, such as the Lorenz attractor. The algorithms compute the derivative of long time averaged "statistical" quantities to infinitesimal perturbations of the system parameters. The algorithms are demonstrated on the Lorenz attractor. We show that sensitivity derivatives of statistical quantities can be accurately estimated using a single, short trajectory (over a time interval of 20) on the Lorenz attractor.

Breaking narrative : narrative complexity in contemporary television
Creators: name: Kroener, Oliver
Publisher: name: University of British Columbia
Year: 2013

description: Emerging from the “quality TV” shows of the early 1980s, contemporary American television shows such as The Sopranos (HBO, 1999 - 2007), Lost (ABC, 2004 - 2010), Game of Thrones (HBO, 2011 - ) and Breaking Bad (AMC, 2008 - 2013) have been frequently praised by critics and scholars for their narrative complexity. However, often neither critics nor scholars define what narrative complexity specifically constitutes. That is to say, what are intricate plotlines? What distinguishes complex characters from “simple” ones? And in what ways do complex television narratives differ from complex feature films? This study takes a cognition-based approach to the topic and discusses the AMC series Breaking Bad as one of the prime examples of narrative complexity in contemporary television. The series revolves around Walter White (Bryan Cranston), a fifty year old high-school chemistry teacher, who is diagnosed with inoperable lung cancer and decides to team up with a former student of his to produce methamphetamine in order to secure a financial future for his family before he dies. Breaking Bad frequently uses “puzzling” narrative devices such as flashbacks, flashforwards, time-jumps or cold opens and aligns its viewers with a main protagonist whose actions are often morally objectionable. During the course of this study, which is primarily based on the works of theorists such as David Bordwell, Edward Branigan, Thomas Elsaesser , Murray Smith and Jason Mittell, I discuss how narration in visual media storytelling operates, what narrative complexity in the television medium constitutes, and how watching “Complex TV” has changed how viewers process television narratives on a cognitive level. In particular, I explore the ways in which contemporary television narratives have adopted trademarks of what Elsaesser has termed “mind-game” films and how engaging with complex characters over the course of several seasons of a series can influence our understanding of the narrative as a whole. However, the study of “Complex TV” has only begun and this work is primarily supposed to generate more discussion about a narrative trend that has left its mark on the current “Golden Age of Television.”

description: Consider a finite dimensional complex Hilbert space $\cH$, with $dim(\cH) \geq 3$, define $\bS(\cH):= \{x\in \cH \:|\: ||x||=1\}$, and let $ν_\cH$ be the unique regular Borel positive measure invariant under the action of the unitary operators in $\cH$, with $ν_\cH(\bS(\cH))=1$. We prove that if a complex frame function $f : \bS(\cH)\to \bC$ satisfies $f \in \cL^2(\bS(\cH), ν_\cH)$, then it verifies Gleason's statement: There is a unique linear operator $A: \cH \to \cH$ such that $f(u) = < u| A u>$ for every $u \in \bS(\cH)$. $A$ is Hermitean when $f$ is real. No boundedness requirement is thus assumed on $f$ {\em a priori}.

description: The first generation of stars had very different properties than later stellar generations, as they formed from a "pristine" gas that was free of heavy elements. Normal star formation took place only after the first stars polluted the surrounding turbulent interstellar gas, increasing its local heavy element concentration, Z, beyond a critical value, Z_c (10^-8 < Z_c <10^-5). Motivated by this astrophysical problem, we investigate the fundamental physics of the pollution of pristine fluid elements in isotropic compressible turbulence. Turbulence stretches the pollutants, produces concentration structures at small scales, and brings the pollutants and the unpolluted flow in closer contact. Our theoretical approach employs the probability distribution function (PDF) method for turbulent mixing. We adopt three PDF closure models and derive evolution equations for the pristine fraction from the models. To test and constrain the theoretical models, we conduct numerical simulations for decaying passive scalars in isothermal turbulent flows with Mach numbers of 0.9 and 6.2, and compute the mass fraction, P(Z_c, t), of the flow with Z < Z_c. In the Mach 0.9 flow, the evolution of P(Z_c, t)$ is well described by a continuous convolution model and dP(Z_c, t)/dt = P(Z_c, t) ln[P(Z_c, t)]/tau_con, if the mass fraction of the polluted flow is larger than ~ 0.1. If the initial pollutant fraction is smaller than ~ 0.1, an early phase exists during which the pristine fraction follows an equation from a nonlinear integral model: dP(Z_c, t)/dt = P(Z_c, t) [P(Z_c, t)-1]/tau_int. The timescales tau_con and tau_int are measured from our simulations. When normalized to the flow dynamical time, the decay of P(Z_ c, t) in the Mach 6.2 flow is slower than at Mach 0.9, and we show that P(Z_c, t) in the Mach 6.2 flow can be well fit using a formula from a generalized version of the self-convolution model.

description: Bacterial biofilms can pose a serious health risk to humans and are less susceptible to antibiotics and disinfection than planktonic bacteria. Here, a novel method for biofilm eradication based on antimicrobial photodynamic therapy utilizing a nanoparticle in conjunction with a BODIPY derivative as photosensitizer was developed. Reactive oxygen species are generated upon illumination with visible light and lead to a strong, controllable and persistent eradication of both planktonic bacteria and biofilms. One of the biggest challenges in biofilm eradication is the penetration of the antimicrobial agent into the biofilm and its matrix. A biocompatible hydrophilic nanoparticle was utilized as a delivery system for the hydrophobic BODIPY dye and enabled its accumulation within the biofilm. This key feature of delivering the antimicrobial agent to the site of action where it is activated resulted in effective eradication of all tested biofilms. Here, 3 bacterial species that commonly form clinically relevant pathogenic biofilms were selected: Escherichia coli, Staphylococcus aureus and Streptococcus mutans. The development of this antimicrobial photodynamic therapy tool for biofilm eradication takes a promising step towards new methods for the much needed treatment of pathogenic biofilms.

On the example of a scalar field with O(N) symmetry we discuss the analytic structure of the flowing action and show how it is possible to derive and solve flow equations for real-time properties such as propagator residues and particle decay widths. The formalism conserves space-time symmetries such as Lorentz or Galilei invariance and allows for improved, self-consistent approximations in terms of derivative expansions in Minkowski space.

description: Context Carcinosarcoma of the pancreas is a rare entity comprising a small subset of all pancreatic neoplasms. Diagnosis is usually established by immunohistochemical examination of the resected specimen. Prognosis is limited to several months after resection. Case report We review the current literature on this rare type of neoplasia, considering histopathological and clinical features. The pathologic findings revealed areas of both adenocarcinoma and sarcoma of the pancreas. The adenocarcinomatous areas localized to the tumor within the head of the pancreas whereas the sarcomatous areas localized to regions of the intraductal component. Discussion Carcinosarcoma of the pancreas is a rare disease having a dismal prognosis. To our knowledge, this carcinosarcoma is the very rare reported case of a primary pancreatic neoplasm with mixed carcinomatous and sarcomatous components.

description: We extend the halo-independent method of Fox, Liu, and Weiner to include energy resolution and efficiency with arbitrary energy dependence, making it more suitable for experiments to use in presenting their results. Then we compare measurements and upper limits on the direct detection of low mass ($\sim10$ GeV) weakly interacting massive particles with spin-independent interactions, including the upper limit on the annual modulation amplitude from the CDMS collaboration. We find that isospin-symmetric couplings are severely constrained both by XENON100 and CDMS bounds, and that isospin-violating couplings are still possible at the lowest energies, while the tension of the higher energy CoGeNT bins with the CDMS modulation constraint remains. We find the CRESST II signal is not compatible with the modulation signals of DAMA and CoGeNT.

description: Using an unbiased quantum Monte Carlo method, we obtain convincing evidence of the existence of a checkerboard supersolid at a {\it commensurate} filling factor 1/2 (commensurate supersolid) in the soft-core Bose-Hubbard model with nearest-neighbor repulsions on a cubic lattice. In conventional cases, supersolids are realized at incommensurate filling factors by a doped-defect-condensation mechanism, where particles (holes) doped into a perfect crystal act as interstitials (vacancies) and delocalize in the crystal order. However, in the above model, a supersolid state is stabilized even at the commensurate filling factor 1/2 {\it without doping}. By performing grand canonical simulations, we obtain a ground-state phase diagram that suggests the existence of a supersolid at a commensurate filling. To obtain direct evidence of the commensurate supersolid, we next perform simulations in canonical ensembles at a particle density $ρ=1/2$ and exclude the possibility of phase separation. From the obtained snapshots, we discuss the microscopic structure and observe that interstitial-vacancy pairs are unbound in the crystal order.

description: Context Isolated pancreatic transection is a rare but well-recognized complication following blunt trauma of the abdomen. Diagnosis at presentation may be difficult and delayed due to subtle initial symptoms and evolving nature of the injury. Case report We describe an isolated complete pancreatic transection in a 14-year-old female secondary to a previously unreported and highly unusual mechanism (being tossed by a wave). Diagnosis was obtained by computed tomography scan 24 hours following initial trauma. She was managed operatively with an open distal pancreatectomy with splenic preservation and no subsequent complications. Conclusions The force sustained from the blunt abdominal trauma of being tossed by a wave can be significant. The management of pancreatic injuries in children, particularly in the context of ductal transection, is controversial. Timely recognition and management is critical to optimal outcomes. Early operative intervention may help to avoid complications such as abscess or pseudocyst formation.

description: In dairy cows the body condition forms a reflection of the energy reserves of the organism. Health, welfare and productivity of dairy cows are strongly associated with changes in body condition. As lactation puts substantial demands on the metabolism of dairy cows, farm management aims at avoiding either a deficient body condition or a substantial loss of body condition within a short period of time. A body condition higher or lower than recommended (over- and underconditioning in the following) compromises dairy cow productivity. While the body condition of Holstein Friesian cows has been thoroughly explored, few is known about the consequences of deviations from a target body condition for health and productivity of cows from other breeds. This study explores the percentage of over- and underconditioned cows at different days post partum [dpp] and their association with production parameters i.e., milk yield, milk fat and milk protein content of Simmental cows on Bavarian farms, categorized by parity (primi- or multiparous). Our study displays that in Simmental cows, overconditioning is more prevalent than underconditioning. While the middle of lactation (dpp = 100–199) resulted in higher percentage of overconditioning, the dry period (dpp = < 0 & > 299) indicated a higher percentage of underconditioned cows. The dry period and the middle of lactation are therefore the most challenging lactation stages for Simmental cows. We found milk protein content to have the strongest association with over- and underconditioning in Simmental cows. The probability of overconditioning was higher with higher milk protein content for every lactation stage and the probability of underconditioning was lower with higher milk protein content in every lactation stage. This study provides a theoretical basis for potential improvements in stockbreeding, which, if implemented, could improve not only the milk yield of Simmental dairy cows, but also their health and welfare.

Case report We describe a case of a 60-year-old woman who presented with right upper quadrant pain and was found to have a reactive nodular hyperplasia of the pancreas involving the uncinate process, body and tail of the gland. Due to the multifocal distribution of these hypoechoic vascular lesions, a total pancreatectomy was performed since malignancy could not be safely excluded. Conclusion There have been a handful of cases reporting reactive lymphoid hyperplasia affecting the pancreas; however, it is uncommon to perform such a radical pancreatic resection for this benign condition.

This review is an update from the 2013 American Society of Clinical Oncology (ASCO) Gastrointestinal Cancer Symposium held in San Francisco, CA, USA. We present the summary of the findings from Abstracts #145 and #269 and discuss the potential impact on our clinical practice on this highly lethal cancer.

description: The lowland paca (Cuniculus paca) is a nocturnal, widespread, and solitary large-sized rodent in the family Cuniculidae, and one of the most frequently hunted mammals in the Neotropical forests of Latin America. We assembled the first complete mitochondrial genome of lowland paca using three closely related hystricognath species as reference sequences. The mitochondrial genome is 16,770 basepairs (bp) in length, with similar characteristics of vertebrate mitochondrial genomes. We performed phylogenetic analyses using 26 mitochondrial genome of hystricognath species based on thirteen protein-coding genes. The result confirms the taxonomical placement among the New World hystricognath rodents with high support. The placement is consistent with previous phylogenetic studies based on individual mitochondrial and nuclear genes. The current study improves the phylogenic resolution of hystricognath rodents.

description: In the past, across the International Federation of Landscape Architects (IFLA) and its regions, numerous initiatives have taken place to collect information on Pathways to Profession. Such initiatives have looked at educational programmes and country-level membership requirements. However, despite a great effort in dealing with these matters, most of the information collected is either incomplete or outdated. Moreover, different databases and formats prevent any data comparison for IFLA members, affiliated organisations and the general public. This makes it difficult for professionals to respond to contemporary worldwide challenges that our globalised society faces, especially the higher demands of free movement. Educational and professional standards differ not only across IFLA Regions but also between countries, which has massive repercussions in employability, career development, exchange of knowledge and other administrative formalities. This is noted in extreme situations when a quick response is needed to unfortunate events like natural disasters or emerging conflicts.

description: Pancreatic cancer is one of the deadliest cancers.  While BRCA-associated pancreatic cancers are uncommon, the distinctive phenotype of this malignancy may offer unique therapeutic targets. At the 2013 American Society of Clinical Oncology (ASCO) Gastrointestinal Cancers Symposium, a review of the characteristics and outcomes of one large case series (Abstract #278), however, did not reveal a benefit to first-line platinum chemotherapy in the treatment of advanced pancreatic cancer.  In another study (Abstract #147), substantial responses were observed in both patients with BRCA2-associated pancreatic cancer treated with the poly-(ADP-ribose) polymerase (PARP) inhibitor ABT-888 (veliparib).

description: We develop a symmetry classification scheme to find ground states of pseudo spin-1/2, spin-1, and spin-2 spin-orbit coupled spinor Bose-Einstein condensates, and show that as the SO(2) symmetry of simultaneous spin and space rotations is broken into discrete cyclic groups, various types of lattice structures emerge in the absence of a lattice potential, examples include two different kagaome lattices for pseudo spin-1/2 condensates and a nematic vortex lattice in which uniaxial and biaxial spin textures align alternatively for spin-2 condensates. For the pseudo spin-1/2 system, although mean-field states always break time-reversal symmetry, there exists a time-reversal invariant many-body ground state, which is fragmented and expected to be observed in a micro-condensate.

description: At the time of diagnosis most of patients present with advanced or metastatic pancreatic cancer, thereby precluding surgical resection. While the standard of care in the first line setting is established, there are limited data to support a standard second-line chemotherapy regimen. The authors summarize two interesting studies (Abstract #263 and Abstract #287) presented at the 2013 ASCO Gastrointestinal Cancers Symposium. These studies concern two phase II trials about second-line chemotherapy in pancreatic cancer. The first one evaluated the role of fluoropyrimidine as monotherapy versus fluoropyrimidine in combination with irinotecan (Abstract #263) and the second one compared the fluoropyrimidine treatment with the continuation of gemcitabine as monotherapy (Abstract #287).

description: Introduction: Abductive reasoning is a type of reasoning that is applied to generate causal explanations. Modeling for inquiry is an important practice in science and science education that involves constructing models as causal explanations for scientific phenomena. Thus, abductive reasoning is applied in modeling for inquiry. Biological phenomena are often best explained as complex systems, which means that their explanations ideally include causes and mechanisms on different organizational levels. In this study, we investigate the role of abductive reasoning in modeling for inquiry and its potential for explaining biological phenomena as complex systems. Methods: Eighteen pre-service science teachers were randomly assigned to model one of two biological phenomena: either a person's reddened face, for which participants knew of explanations from their everyday lives, or a clownfish changing its sex, for which participants did not know about explanations. Using the think-aloud method, we examined the presence of abductive reasoning in participants' modeling processes. We also analyzed modeling processes in terms of participants' ability to model the phenomena as complex systems. Results: All participants reasoned abductively when solving the modeling task. However, modeling processes differed depending on the phenomenon. For the reddened face, participants generated simple models that they were confident with. In contrast, for the clownfish, participants generated more complex models that they were insecure about. Extensive engagement in abductive reasoning alone did not lead to the generation of models that explained the phenomena as complex systems. Discussion: Based on the findings, we conclude that engagement in abductive reasoning will not suffice to explain phenomena as complex systems. We suggest examining in future studies how abductive reasoning is combined with systems thinking skills to explain phenomena as complex systems in biological model construction.

description: Pancreatic cancer is one of the most lethal malignancies with a mortality rate almost equal to its incidence. It is ranked as the fourth leading cause of cancer-related deaths in the United States, and despite intensive basic and clinical research over the last few years, the survival benefit for the majority of patients with pancreatic cancer is still disappointing. Due to the absence of specific symptoms and the lack of early detection tests, pancreatic cancer is usually diagnosed at an advanced inoperrable stage and palliative chemotherapy with the purine analogue gemcitabine in combination with the targeted agent erlotinib, remains the mainstay method in the management of these patients. Therefore, there is an imperative need for new findings in the translational research field with prognostic, predictive and therapeutic value. In this paper we summarize five most interesting research abstracts as presented at the 2013 American Society of Clinical Oncology (ASCO) Gastrointestinal Cancers Symposium. In particular, we focus on Abstract #141 which investigates the interaction between liver and pancreatic organ damage in patients with pancreatic cancer and the potential contribution of the patatin-like phospholipase domain containing 3 (PNPLA3) gene variation in pancreatic cancer development and on Abstract #149, in which, the prognostic and predictive role of SWI/SNF complex, a chromatin-remodeling complex, is examined. The key role of pharmacogenomics, in terms of predicting response and resistance to chemotherapy in pancreatic cancer patients, is analyzed in Abstract #142 and the contribution of circulating tumor cell detection in the early diagnosis of pancreatic cancer, allowing the avoidance of more invasive procedures like EUS-FNA, is discussed in Abstract #157. Lastly, in Abstract #164, the diagnostic utility of YKL-40 and IL-6 in pancreatic cancer patients is investigated.

description: Activin and Bone Morphogenetic Protein (BMP) signaling plays crucial roles in vertebrate organ formation, including osteo- and angiogenesis, and tissue homeostasis, such as neuronal maintenance. Activin and BMP signaling needs to be precisely controlled by restricted expression of shared receptors, stoichiometric composition of receptor-complexes and presence of regulatory proteins. A R206H mutation in the human (hs) BMP type I receptor hsACVR1, on the other hand, leads to excessive phosphorylation of Sons of mothers against decapentaplegic (SMAD) 1/5/8. This in turn causes increased inflammation and heterotopic ossification in soft tissues of patients suffering from Fibrodysplasia Ossificans Progressiva (FOP). Several animal models have been established to understand the spontaneous and progressive nature of FOP, but often have inherent limitations. The Japanese medaka (Oryzias latipes, ola) has recently emerged as popular model for bone research. To assess whether medaka is suitable as a potential FOP animal model, we determined the expression of Activin receptor type I (ACVR1) orthologs olaAcvr1 and olaAcvr1l with that of Activin type II receptors olaAcvr2ab, olaAcvr2ba and olaAcvr2bb in embryonic and adult medaka tissues by in situ hybridization. Further, we showed that Activin A binding properties are conserved in olaAcvr2, as are the mechanistic features in the GS-Box of both olaAcvr1 and olaAcvr1l. This consequently leads to FOP-typical elevated SMAD signaling when the medaka type I receptors carry the R206H equivalent FOP mutation. Together, this study therefore provides experimental groundwork needed to establish a unique medaka model to investigate mechanisms underlying FOP.

description: Intraductal papillary mucinous neoplasms of the pancreas (IPMNs) are potentially malignant intraductal epithelial neoplasms which consist of columnar, mucin-containing cells and arise from the epithelium of the main pancreatic duct or its branches. IPMNs as well as pancreatic intraepithelial neoplasias (PanINs) and mucinous cystic neoplasms represent noninvasive precursors of invasive ductal adenocarcinoma of the pancreas. The diagnosis of IPMNs includes radiographic (CT scanning, MRI, MRCP) and endoscopic evaluation (ERCP, EUS), PET, as well as serum tumor markers and molecular markers. The Sendai Consensus Guidelines help guide surgical resection for patients with IPMN. The follow-up of these patients, as well as of those who do not undergo surgical resection, is of great importance, since patients with IPMN appear to be at risk for other malignancies. Herein, the authors summarize the data presented at the 2013 ASCO Gastrointestinal Cancers Symposium regarding incidence and clinicopathological characteristics of IPMN (Abstracts #324, #187 and #179).

A witness for topological order and stable quantum memories in abelian anyonic systems

description: We propose a novel parameter, the anyonic topological entropy, designed to detect the error correcting phase of a topological memory. Unlike similar quantities such as the topological entropy, the anyonic topological entropy is defined using the states of the anyon occupations. As such, though the parameter deals with phases and phase transitions that are quantum in nature, it can be calculated solely from classical probability distributions. In many cases, these calculations will be tractable using efficient classical algorithms. The parameter therefore provides a new avenue for efficient studies of anyonic systems.

description: The water distribution system in the lairage pens of abattoirs could act as a route of contamination for produced meat. In this study, biofilm formation and the occurrence of specific pathogens in drinking equipment was investigated in different lairage pens in a German commercial pig abattoir. Samples of the water and the drinkers in different locations were microbiologically cultivated and examined. After new drinking equipment had been installed for one month, three months and five years, biofilm formation was detectable, and retrograde growth from the nipple drinkers was seen up to the connection with the main water distribution system. In particular, Enterobacteriaceae and Pseudomonas spp. were found in all samplings of the nipple drinkers. Zoonotic pathogens, Salmonella, pathogenic Yersinia enterocolitica and methicillin-resistant Staphylococcus aureus, were also isolated from the nipple drinkers, while Listeria monocytogenes was not detected via microbial cultivation methods in any of the samples. Since the pigs take the contaminated nipple drinkers into their mouths to drink, or drink contaminated water containing the pathogens, transmission and even infection of the pigs in the lairage can be assumed. This could consequently lead to contamination or cross-contamination of the meat during slaughter and processing and to a public health risk.
