description: We argue that more effective management of climate risk must be part of the response of the international agriculture community to the double crisis of persistent poverty and a changing climate. The most promising opportunities to adapt to climate change involve action on shorter time scales that also contributes to immediate development challenges. Climate risk management (CRM) combines systematic use of climate information, and technology that reduces vulnerability and policy that transfers risk. The cost of climate risk comes both through damaging extreme events and through forfeited opportunity in climatically-favorable years. Effective CRM therefore involves managing the full range of variability, balancing hazard management with efforts to capitalize on opportunity. We discuss several innovations for managing climate risk in agriculture, which have not yet been fully mainstreamed in international agricultural research-for-development. First, effective rural climate information services enable farmers to adopt technology, intensify production, and invest in more profitable livelihoods when conditions are favorable; and to protect families and farms against the long-term consequences of adverse extremes. Second, information and decision support systems synthesize historic, monitored and forecast climate information into forms that are directly relevant to institutional decisions (planning, trade, food crisis response) that impact farmer livelihoods. Third, innovations in index-based insurance and credit overcome some of the limitations of traditional insurance, and are being applied to pre-financing food crisis response, and to removing credit constraints to adopting improved technology. We present a typology of CRM interventions around the concept of dynamic poverty traps.
Unconventional Peierls physics in underdoped Bi2201

description: The puzzling physics of the high-temperature superconducting cuprates has led to many important questions and investigations regarding the mechanism of high-Tc's. This dissertation demonstrates that, through detailed experimental studies using angle-resolved photoemission (ARPES) and low-energy electron diffraction (LEED), a new type of periodic structural distortion exists in Bi₂Sr₂-xLaxCuO₆₊d (La-Bi2201), leading to the existence of multiple periodic lattice distortions (PLD) in the underdoped material. Photon-energy dependent ARPES reveals photoelectron diffraction effects that exhibit all relevant length scales as oscillations in the ARPES matrix element, leading to the observation of all of the diffraction-replica (DR) bands associated with the multiple PLD's. Furthermore, a charge-density-wave (CDW) associated with the new PLD at the crystal surface with a temperature-dependent wavelength is observed. A Ginzburg-Landau mean field model is shown to exhibit the same temperature-dependence from a combination of Fermi surface nesting and lattice commensurability affected by the temperature-dependent harmonic content of the CDW. A detailed temperature-dependence of the antinodal pseudogap reveals two simultaneous energy and temperature scales: one associated with the CDW, and the other in agreement with the magneto-optical Kerr effect and magnetic neutron diffraction results in the literature. Detailed nodal ARPES lineshapes reveal a peak in the real-part of the self-energy that coincides with band-crossing positions and the nodal ''kink'' energies for all dopings, providing evidence that these disparate features can be collectively explained by band hybridization allowed in the fully incommensurate crystal, which does not preserve parity. This provides one route to explain these phenomena - as a product of nested van-Hove singularities along the nodal line in underdoped La-Bi2201, which result in a Peierls distortion similar to the dichalcogenide CDW superconductors.

description: Einkommensschwache Haushalte können sich nachhaltige Produkte – wie Bio-Lebensmittel oder Fairtrade-Kleidung – oft nicht leisten. Das Gefühl von Einkommensungleichheit wird durch das Bedürfnis nach nachhaltigen, aber teureren Produkten verstärkt. Was kann der Staat in einer solchen Situation tun, wenn er also einerseits umweltfreundliches Verhalten fördern und andererseits damit verbundene größere Unterschiede zwischen armen und reichen Haushalten abmildern will? Die auf Daten aus den USA basierenden Modellergebnisse dieses Wochenberichts verdeutlichen das Dilemma: Der Staat kann nicht Steuern und Abgaben zum Schutz der Umwelt, wie eine Tierwohlabgabe, erhöhen und zugleich mittels Einkommensteuererhöhungen mehr umverteilen. Denn beides führt in der Theorie dazu, dass insgesamt weniger produziert wird und die gesamtwirtschaftliche Wohlfahrt sinkt. Die richtige Balance beider Instrumente hängt sowohl von der Einkommensungleichheit in einem Land als auch vom Preisunterschied zwischen nachhaltigen und nichtnachhaltigen Produkten ab. In jedem Fall muss die finanzielle Situation einkommensschwacher Haushalte bedacht werden, wenn der Trend, nachhaltig zu konsumieren, steigen soll.

description: The resistivity of a dense crystalline array of semiconductor nanocrystals (NCs) depends in a sensitive way on the level of doping as well as on the NC size and spacing. The choice of these parameters determines whether electron conduction through the array will be characterized by activated nearest-neighbor hopping or variable-range hopping (VRH). Thus far, no general theory exists to explain how these different behaviors arise at different doping levels and for different types of NCs. In this paper we examine a simple theoretical model of an array of doped semiconductor NCs that can explain the transition from activated transport to VRH. We show that in sufficiently small NCs, the fluctuations in donor number from one NC to another provide sufficient disorder to produce charging of some NCs, as electrons are driven to vacate higher shells of the quantum confinement energy spectrum. This confinement-driven charging produces a disordered Coulomb landscape throughout the array and leads to VRH at low temperature. We use a simple computer simulation to identify different regimes of conduction in the space of temperature, doping level, and NC diameter. We also discuss the implications of our results for large NCs with external impurity charges and for NCs that are gated electrochemically.

description: An assessment of the recorded integrated luminosity is presented for data collected with the D0 detector at the Fermilab Tevatron Collider from June 2006 to September 2011 (Run IIb). In addition, a measurement of the effective cross section for inelastic interactions, also referred to as the luminosity constant, is reported. This measurement incorporates new features that lead to a substantial improvement in the precision of the result. A luminosity constant of σ_{LM} = 48.3\pm1.9\pm0.6 mb is obtained, where the first uncertainty is due to the accuracy of the inelastic cross section used by both CDF and D0, and the second uncertainty is due to D0 sources. The recorded luminosity for the highest E_T jet trigger is L_rec = 9.2 \pm 0.4 fb^{-1}, with a relative uncertainty of 4.3%.

We use this to re-obtain a known result, the existence of a universal finitely presented torsion-free group; one into which all finitely presented torsion-free groups embed. We apply our techniques to show that recognising embeddability of finitely presented groups is $Π^{0}_{2}$-hard, $Σ^{0}_{2}$-hard, and lies in $Σ^{0}_{3}$. We also show that the sets of orders of torsion elements of finitely presented groups are precisely the $Σ^{0}_{2}$ sets which are closed under taking factors.

description: Two-photon imaging has become a useful tool for optical monitoring of neural circuits, but it requires high laser power and serial scanning of each pixel in a sample. This results in slow imaging rates, limiting the measurements of fast signals such as neuronal activity. To improve the speed and signal-to-noise ratio of two-photon imaging, we introduce a simple modification of a two-photon microscope, using a diffractive optical element (DOE) which splits the laser beam into several beamlets that can simultaneously scan the sample. We demonstrate the advantages of DOE scanning by enhancing the speed and sensitivity of two-photon calcium imaging of action potentials in neurons from neocortical brain slices. DOE scanning can easily improve the detection of time-varying signals in two-photon and other non-linear microscopies.

description: We extend the description of flavour that exists in the Randall-Sundrum (RS) model to the soft wall (SW) model in which the IR brane is removed and the Higgs is free to propagate in the bulk. It is demonstrated that, like the RS model, one can generate the hierarchy of fermion masses by localising the fermions at different locations throughout the space. However, there are two significant differences. Firstly the possible fermion masses scale down, from the electroweak scale, less steeply than in the RS model and secondly there now exists a minimum fermion mass for fermions sitting towards the UV brane. With a quadratic Higgs VEV, this minimum mass is about fifteen orders of magnitude lower than the electroweak scale. We derive the gauge propagator and despite the KK masses scaling as $m_n^2\sim n$, it is demonstrated that the coefficients of four fermion operators are not divergent at tree level. FCNC's amongst kaons and leptons are considered and compared to calculations in the RS model, with a brane localised Higgs and equivalent levels of tuning. It is found that since the gauge fermion couplings are slightly more universal and the SM fermions typically sit slightly further towards the UV brane, the contributions to observables such as $ε_K$ and $Δm_K$, from the exchange of KK gauge fields, are significantly reduced.

description: Um die deutschen Klimaziele zu erreichen, müssen die Treibhausgasemissionen bis zum Jahr 2030 um 65 Prozent im Vergleich zu 1990 reduziert werden. Fast ein Drittel dieser Emissionen wird in Deutschland durch den Konsum privater Haushalte verursacht. Auf Basis des Sozio-oekonomischen Panels (SOEP) werden die CO2-Emissionsäquivalente von Haushalten in Deutschland aus drei wichtigen Bereichen errechnet: Wohnen, Mobilität und Ernährung. Allein der Konsum in diesen drei Bereichen hat Emissionen zur Folge, die das für Privatpersonen angestrebte Emissionsbudget im Durchschnitt um mehr als das Doppelte übersteigen. Die Emissionen aus den Bereichen Mobilität und Wohnen machen den größten Teil der Emissionen aus. Die Emissionen steigen mit dem Einkommen, insbesondere im Bereich Mobilität. Hier schlagen vor allem Flugreisen zu Buche. Im Bereich Ernährung trägt vor allem der Fleischkonsum zu den Emissionen bei, im Bereich Wohnen unter anderem die Größe des Haushalts und die Gebäudeart. Indem die größten Treiber der Emissionen in den drei Bereichen identifiziert werden, lassen sich zielgerichtete politische Hebel benennen, wie eine Vereinfachung des Wohnungstauschs und die energieeffiziente Sanierung von Wohngebäuden sowie ein Verbot von Kurzstreckenflügen und eine Tierwohlabgabe.

description: We report here the design, synthesis and application of pyrene binary oligonucleotide probes for selective detection of cellular mRNA. The detection strategy is based on the formation of a fluorescent excimer when two pyrene groups are brought into close proximity upon hybridization of the probes with the target mRNA. The pyrene excimer has a long fluorescence lifetime (>40 ns) compared with that of cellular extracts (∼7 ns), allowing selective detection of the excimer using time-resolved emission spectra (TRES). Optimized probes were used to target a specific region of sensorin mRNA yielding a strong excimer emission peak at 485 nm in the presence of the target and no excimer emission in the absence of the target in buffer solution. While direct fluorescence measurement of neuronal extracts showed a strong fluorescent background, obscuring the detection of the excimer signal, time-resolved emission measurements indicated that the emission decay of the cellular extracts is ∼8 times faster than that of the pyrene excimer probes. Thus, using TRES of the pyrene probes, we are able to selectively detect mRNA in the presence of cellular extracts, demonstrating the potential for application of pyrene excimer probes for imaging mRNAs in cellular environments that have background fluorescence.

Population structure in harbour porpoises (Phocoena phocoena) of British Columbia and widespread hybridization in cetaceans
Creators: name: Crossman, Carla Anne
Publisher: name: University of British Columbia
Year: 2012

description: Harbour porpoises (Phocoena phocoena) are one of the most abundant small cetaceans in the world and, while they are extensively studied across most of their range, little is known about their biology in British Columbia, Canada. Recent management plans have identified a need to better understand the population structure of harbour porpoises in this region. I investigated the genetic population structure of harbour porpoises in British Columbia using mitochondrial DNA (mtDNA) and eight microsatellite loci. My findings are consistent with a single population of harbour porpoises inhabiting the coastline between Haida G’waii and the southern Juan de Fuca Strait. I also confirmed that hybridization between harbour porpoises and Dall’s porpoises (Phocoenoides dalli) has occurred over a larger geographic region than previously known and I present evidence that the resultant hybrids are reproductively viable and have the potential to successfully backcross with both parental species. Building on these findings, I examined patterns of hybridization across the order Cetacea. I found that species pairs that share a greater number of ecological, morphological, and behavioural traits have a higher propensity to hybridize than species pairs that do not. This trend is largely driven by behavioural and morphological traits such as vocalization frequency and body size. My study aids in understanding harbour porpoise population structure in British Columbia, and highlights the occurrence of widespread cetacean hybridization.

description: Die Phase zunehmender Globalisierung scheint mit der weltweiten Finanzkrise im Jahr 2008 zu Ende gegangen sein, was sich nicht nur im sinkenden Welthandel relativ zur Wertschöpfung ausdrückt. Auch in der internationalen Finanzarchitektur ist dieser Trend zu beobachten. Hier zeigt er sich in der zunehmenden Bereitschaft, mit Devisenmarktinterventionen auf Wechselkurse einzuwirken. Immer mehr Länder entscheiden sich für rigidere Wechselkursregime und höhere Währungsreserven (relativ zur Wertschöpfung) bei unveränderter Fähigkeit zu Interventionen, wie dieser Wochenbericht zeigt. Daran lässt sich ablesen, dass das Vertrauen in die Preisbildung auf den freien Märkten abnimmt und die Bereitschaft zur politischen Kontrolle steigt. Dies ist ein weiterer Schritt weg von einer westlich dominierten, multilateral geordneten Weltwirtschaft, hin zu einer Welt, in der Länder stärker ad hoc agieren.

description: Glioblastomas (GBM) are highly radioresistant and lethal brain tumors. Ionizing radiation (IR)- induced DNA double-strand breaks (DSBs) are a risk factor for the development of GBM. In this study, we systematically examined the contribution of IR-induced DSBs to GBM development using transgenic mouse models harboring brain-targeted deletions of key tumor suppressors frequently lost in GBM, namely Ink4a, Ink4b, Arf, and/or PTEN. Using low linear energy transfer (LET) X-rays to generate simple breaks or high LET Fe ions to generate complex breaks, we found that DSBs induce high-grade gliomas in these mice which, otherwise, do not develop gliomas spontaneously. Loss of Ink4a and Arf was sufficient to trigger IR-induced glioma development but additional loss of Ink4b significantly increased tumor incidence. We analyzed IR-induced tumors for copy number alterations (CNAs) to identify oncogenic changes that were generated and selected for as a consequence of stochastic DSB events. We found Met amplification to be the most significant oncogenic event in these radiation-induced gliomas. Importantly, Met activation resulted in expression of Sox2, a GBM cancer stem cell (CSC) marker, and was obligatory for tumor formation. In sum, these results indicate that radiation-induced DSBs cooperate with loss of Ink4 and Arf tumor suppressors to generate high-grade gliomas that are commonly driven by Met amplification and activation.

description: Investigating the year-round rainfall of Sri Lanka provides understanding into the South Asian monsoon system as it compliments studies on the Indian summer monsoon. The El Niño-Southern Oscillation (ENSO) is a primary mode of climate variability of this area. Here, the predictability of Sri Lanka rainfall based on ENSO is quantified based on composite analysis, correlations and contingency tables. The rainfall is modestly predictable based on ENSO during January-March, July-August and October-December. El Niño typically leads to wetter conditions during October to December and drier conditions during January to March and July to August on average. The correlations of ENSO indices with rainfall are statistically significant for October to December, January to March and July to August and an analysis based on contingency tables shows modest predictability. The use of ENSO indices derived from the central Pacific sea surfaces improves the predictability from January to June. The predictability in the mountain regions is diminished when garnering orographic rainfall. The predictability in the east is diminished during the cyclone season. The predictability based on ENSO for October to December rainfall is robust on a decadal scale while the predictability of January to March and July to August rainfall has acquired significance in recent decades. An ENSO-based scheme that is adapted to each season and region, and takes account of decadal variations can thus provide skillful rainfall predictions.

description: Minimum energy configurations in celestial mechanics are investigated. It is shown that this is not a well defined problem for point-mass celestial mechanics but well-posed for finite density distributions. This naturally leads to a granular mechanics extension of usual celestial mechanics questions such as relative equilibria and stability. This paper specifically studies and finds all relative equilibria and minimum energy configurations for $N=1,2,3$ and develops hypotheses on the relative equilibria and minimum energy configurations for $N\gg 1$ bodies.

description: The dynamic properties of two-photon pumped blue lasing (~470  nm) in the solution of an organic chromophore [2-acetyl-6-(dimethylamino)naphthalene], excited by ~160-fs laser pulses at ~775  nm, have been studied. Both the forward and backward stimulated emission are enhanced by feedback from the reflection at the two optical windows of the solution filled cuvette. Under current experimental conditions, the lasing wavelengths in the forward and backward directions were almost the same, but both blueshifted compared to the fluorescence peak wavelength of the sample solution. The temporal behavior of the lasing output was recorded by a high-speed streak camera system. The multipulse structure and spectral properties of the output lasing are semiquantitatively explained. In addition, excellent optical phase-conjugation properties of the backward stimulated emission were observed; the aberration influences from an aberrator on the backward lasing beam were automatically removed.

description: The aryl hydrocarbon receptor repressor (AHRR) is a bHLH/Per-ARNT-Sim transcription factor located in a region of chromosome 5 (5p15.3) that has been proposed to contain one or more tumor suppressor genes. We report here consistent downregulation of AHRR mRNA in human malignant tissue from different anatomical origins, including colon, breast, lung, stomach, cervix, and ovary, and demonstrate DNA hypermethylation as the regulatory mechanism of AHRR gene silencing. Knockdown of AHRR gene expression in a human lung can- cer cell line using siRNA significantly enhanced in vitro anchorage-dependent and -independent cell growth as well as cell growth after transplantation into immunocompromised mice. In addition, knockdown of AHRR in non-clonable normal human mammary epithelial cells enabled them to grow in an anchorage-independent manner. Further, downregulation of AHRR expression in the human lung cancer cell line conferred resistance to apoptotic signals and enhanced motility and invasion in vitro and angiogenic potential in vivo. Ectopic expression of AHRR in tumor cells resulted in diminished anchorage-dependent and -independent cell growth and reduced angiogenic potential. These results therefore demonstrate that AHRR is a putative new tumor suppressor gene in multiple types of human cancers.

description: Public opinion polarization is here conceived as a process of alignment along multiple lines of potential disagreement and measured as growing constraint in individuals' preferences. Using NES data from 1972 to 2004, the authors model trends in issue partisanship--the correlation of issue attitudes with party identification--and issue alignment--the correlation between pairs of issues--and find a substantive increase in issue partisanship, but little evidence of issue alignment. The findings suggest that opinion changes correspond more to a resorting of party labels among voters than to greater constraint on issue attitudes: since parties are more polarized, they are now better at sorting individuals along ideological lines. Levels of constraint vary across population subgroups: strong partisans and wealthier and politically sophisticated voters have grown more coherent in their beliefs. The authors discuss the consequences of partisan realignment and group sorting on the political process and potential deviations from the classic pluralistic account of American politics.

description: Well-differentiated papillary mesotheliomas (WDPMs) are usually encountered as incidental findings in the peritoneal cavity in women. Most WDPMs are benign, and the histologic features that indicate a more aggressive course are controversial. We report 20 cases of WDPM, which contained invasive foci. Thirteen cases arose in the peritoneal cavity, 1 in a hernia sac, 3 in the pleural cavity, and 3 in hydroceles. The female:male ratio was 16:4, and age range was 7 to 74 years. Tumor was multifocal in 15 cases. Some tumors showed back-to-back papillae, a pattern mimicking invasion but discernible on pan-keratin stain as compressive crowding. True invasive patterns ranged from simple bland-appearing glands invading the stalks of the papillae to solid foci of invasive tumor of higher cytologic grade than the original WDPM. All 5 tested cases were negative for p16 deletion by fluorescence in situ hybridization, but 2/3 had abnormal karyotypes. Recurrences were seen in 8 patients, and in 4 multiple recurrences were documented. Of 16 patients with follow-up, 14 are alive from periods of 6 months to 6 years (average 3.5 y), and 2 have known recurrent disease. One patient died of disseminated tumor at 8 years but without histologic confirmation of the nature of the tumor. We conclude that WDPM with invasive foci in the papillae appear to be prone to multifocality and recurrence, but that they rarely give rise to life-threatening disease. We suggest that these lesions be called WDPM with invasive foci to alert clinicians to the possibility of recurrence.

Structure of finite sphere packings via exact enumeration: Implications for colloidal crystal nucleation

description: We analyze the geometric structure and mechanical stability of a complete set of isostatic and hyperstatic sphere packings obtained via exact enumeration. The number of nonisomorphic isostatic packings grows exponentially with the number of spheres $N$, and their diversity of structure and symmetry increases with increasing $N$ and decreases with increasing hyperstaticity $H \equiv N_c - N_{ISO}$, where $N_c$ is the number of pair contacts and $N_{ISO} = 3N-6$. Maximally contacting packings are in general neither the densest nor the most symmetric. Analyses of local structure show that the fraction $f$ of nuclei with order compatible with the bulk (RHCP) crystal decreases sharply with increasing $N$ due to a high propensity for stacking faults, 5- and near-5-fold symmetric structures, and other motifs that preclude RHCP order. While $f$ increases with increasing $H$, a significant fraction of hyperstatic nuclei for $N$ as small as 11 retain non-RHCP structure. Classical theories of nucleation that consider only spherical nuclei, or only nuclei with the same ordering as the bulk crystal, cannot capture such effects. Our results provide an explanation for the failure of classical nucleation theory for hard-sphere systems of $N\lesssim 10$ particles; we argue that in this size regime, it is essential to consider nuclei of unconstrained geometry. Our results are also applicable to understanding kinetic arrest and jamming in systems that interact via hard-core-like repulsive and short-ranged attractive interactions.

description: De novo CD5-positive diffuse large B- cell lymphoma (CD5+ DLBCL) is a subtype of DLBCL found predominantly in older individuals. This particular subtype has been associated with a female pre- dominance and a more aggressive clinical course. Conversely, this entity has not been described in the pe- diatric population. We report a case of a 12 year-old boy who presented with an ileocecal intussusception. Radiologic, morphologic, and immunophenotypic analysis revealed an isolated extranodal mass consistent with a CD5+ DLBCL, germinal center cell phenotype. Fluorescent in situ hybridization analysis was nega- tive for cMYC, BCL6, BCL2, MLL, and IGH/CCND1 rearrangement and showed loss of one copy of MLL in 32% cells. The patient was treated with four cycles of cyclophosphamide, vincristine, prednisolone, methotrexate, and doxorubicin and achieved complete remission. To the best of our knowledge, this is the first detailed report of a de novo CD5+ DLBCL occurring in a child.

description: We have investigated quantum phase transition employing the quantum renormalization group (QRG) method while in most previous literature barely entanglement (concurrence) has been demonstrated. However, it is now well known that entanglement is not the only signature of quantum correlations and a variety of computable measures have been developed to characterize quantum correlations in the composite systems. As an illustration, two cases are elaborated: one dimensional anisotropic (i) XXZ model and (ii) XY model, with various measures of quantum correlations, including quantum discord (QD), geometric discord (GD), measure-induced disturbance (MID), measure-induced nonlocality (MIN) and violation of Bell inequalities (eg. CHSH inequality). We have proved that all these correlation measures can effectively detect the quantum critical points associated with quantum phase transitions (QPT) after several iterations of the renormalization in both cases. Nonetheless, it is shown that some of their dynamical behaviors are not totally similar with entanglement and even when concurrence vanishes there still exists some kind of quantum correlations which is not captured by entanglement. Intriguingly, CHSH inequality can never be violated in the whole iteration procedure, which indicates block-block entanglement can not revealed by the CHSH inequality. Moreover, the nonanalytic and scaling behaviors of Bell violation have also been discussed in detail. As a byproduct, we verify that measure-induced disturbance is exactly equal to the quantum discord measured by σ_z for general X-structured states.
