description: We attempt to generalize the familiar covariantly conserved Bel-Robinson tensor B_{mnab} ~ R R of GR and its recent topologically massive third derivative order counterpart B ~ RDR, to quadratic curvature actions. Two very different models of current interest are examined: fourth order D=3 "new massive", and second order D>4 Lanczos-Lovelock, gravity. On dimensional grounds, the candidates here become B ~ DRDR+RRR. For the D=3 model, there indeed exist conserved B ~ dRdR in the linearized limit. However, despite a plethora of available cubic terms, B cannot be extended to the full theory. The D>4 models are not even linearizable about flat space, since their field equations are quadratic in curvature; they also have no viable B, a fact that persists even if one includes cosmological or Einstein terms to allow linearization about the resulting dS vacua. These results are an unexpected, if hardly unique, example of linearization instability.

description: Die noch erhöhte Inflation sowie die schwache Binnen- und Auslandsnachfrage, die die deutsche Wirtschaftsleistung schon im vergangenen Jahr belastet haben, werden wohl auch das laufende erste Quartal im Minus enden lassen. Die in Deutschland und im gesamten Euroraum deutlich sinkende Inflation, die sich wieder dem Zwei-Prozent-Ziel der Europäischen Zentralbank annähert, lässt eine Zinswende im Frühsommer erwarten. Die abflauende Preisdynamik und die sich verbessernden Finanzierungsbedingungen dürften sowohl den privaten Konsum als auch die Unternehmensinvestitionen im Jahresverlauf etwas ankurbeln. Dennoch bleibt zunächst viel Unsicherheit, insbesondere über die weiteren wirtschaftspolitischen Rahmenbedingungen, was die Haushalte und Unternehmen noch zurückhaltend agieren lässt. Zusätzlich fehlen sowohl fiskalpolitische Impulse als auch die stützende Nachfrage aus dem Ausland. Daher wird das Wachstum des Bruttoinlandsprodukts in diesem Jahr wohl stagnieren und – getragen durch privaten Konsum und öffentliche Ausrüstungsinvestitionen – im kommenden Jahr mit 1,2 Prozent deutlicher zulegen. Die Weltwirtschaft wird sich weiterhin robuster als Deutschland entwickeln. Sie wächst voraussichtlich in diesem und im kommenden Jahr um jeweils 3,5 Prozent, was nach und nach auch die deutschen Exporte stärken dürfte.

description: We report the discovery of a wide brown dwarf companion to the mildly metal-poor ([Fe/H]=-0.24), low galactic latitude (b = 1.88 deg) K4V star HIP 38939. The companion was discovered by its common proper motion with the primary and its red optical (Pan-STARRS1) and blue infrared (2MASS) colors. It has a projected separation of 1630 AU and a near-infrared spectral type of T4.5. As such it is one of only three known companions to a main sequence star which have early/mid-T spectral types (the others being HN Peg B and eps Indi B). Using chromospheric activity we estimate an age for the primary of 900{+1900,-600} Myr. This value is also in agreement with the age derived from the star's weak ROSAT detection. Comparison with evolutionary models for this age range indicates that HIP 38939B falls in the mass range 38+/-20 Mjup with an effective temperature range of 1090+/-60 K. Fitting our spectrum with atmospheric models gives a best fitting temperature of 1100 K. We include our object in an analysis of the population of benchmark T dwarfs and find that while older atmospheric models appeared to over-predict the temperature of the coolest objects compared to evolutionary models, more recent atmospheric models provide better agreement.

Tiny changes incorporated into final version: added analysis of likelihood of companionship, clarified the fitting proceedure, and updated the benchmark analysis to highlight when the quoted evolutionary models use the atmospheric model they are being compared to as a boundary condition

description: The Syrian conflict, which broke out in 2011, has led to a rise in the number of Syrians seeking refuge in the United Kingdom (Karyotis et al., 2021). At the time of this study, approximately 20,000 Syrians have been resettled under Vulnerable Persons Resettlement Scheme (UK Parliament, 2019) and a further, 21,168 Syrians have been granted refugee status between (Migration Observatory, 2022). A review of the existing psychological literature shows that there has been scholarly interest in Syrian migrants (Tinghog et al., 2017; Cantekin & Gencoz, 2017), but very few of these studies are concerned with understanding Syrians’ perceptions and interpretations of their resettlement experiences. In light of this identified gap, the present study aimed to explore the subjective experiences of six forced Syrian migrants in the UK and their coping methods. Semi-structured interviews were conducted with each participant and transcribed. Transcripts were then analysed using Smith et al.’s (2019) a step-by-step guide to Interpretative Phenomenological Analysis (IPA). Four superordinate themes emerged through the analytical process: (1) Thrown in the deep end: the initial changes and challenges of being in the UK, (2) Tensions with identity and self- construal, (3) The ongoing search for belonging: facets of a home, and (4) Means of coping. These findings have been contextualised within the existing literature and their implications for clinical practice and policy have been discussed. Finally, the limitations of the current study and subsequent recommendations for future research have been proposed.

description: The Carnot-like heat engines are classified into three types (normal-, sub- and super-dissipative) according to relations between the minimum irreversible entropy production in the "isothermal" processes and the time for completing those processes. The efficiencies at maximum power of normal-, sub- and super-dissipative Carnot-like heat engines are proved to be bounded between $η_C/2$ and $η_C/(2-η_C)$, $η_C /2$ and $η_C$, 0 and $η_C/(2-η_C)$, respectively. These bounds are also shared by linear, sub- and super-linear irreversible Carnot-like engines [Tu and Wang, Europhys. Lett. 98, 40001 (2012)] although the dissipative engines and the irreversible ones are inequivalent to each other.

description: What is the effect of option categorization on choosers' satisfaction? A combination of field and laboratory experiments reveals that the mere presence of categories, irrespective of their content, positively influences the satisfaction of choosers who are unfamiliar with the choice domain. This "mere categorization effect" is driven by a greater number of categories signaling greater variety among the available options, which allows for a sense of self-determination from choosing. This effect, however, is attenuated for choosers who are familiar with the choice domain, who do not rely on the presence of categories to perceive the variety available.
The pulmonary profile of competitive swimmers
Creators: name: Labreche, Jane Marie
Publisher: name: University of British Columbia
Year: 2012

description: Purpose: The purpose of this thesis was to investigate the nature of the following conditions in competitive swimmers: the occurrence of exercise-induced arterial hypoxemia (EIAH), and the relationship to gender and exercise-induced bronchoconstriction (EIB) (Study 1), and the development of exercise-induced pulmonary edema (PE), and changes in oxyhemoglobin saturation (Study 2). Methods: Study 1: Twenty-one well-trained swimmers (10 male, 11 female) completed a eucapnic voluntary hyperpnea test and an incremental swim test to exhaustion with pre and post-exercise spirometry. Metabolic data (VO₂, VCO₂, ventilation and heart rate) along with oxyhemoglobin saturation (SpO₂) were collected throughout exercise. Study 2: Baseline lung density was obtained in eight well-trained male swimmers using computerized tomography after 24 hours rest. After a standard warm-up, subjects performed 6 x 50m maximal effort intervals on 90 s. Oxyhemoglobin saturation (SpO₂) and heart rate were collected across exercise intervals. Scans were repeated at 45-60 min post-exercise. Results: Study 1: Eleven of the twenty-one subjects tested positive for EIB. No subjects fulfilled our criteria for EIAH (SpO₂ ≤95% or ≥3% drop from resting values) despite a small mean drop in SpO₂ from rest to maximal exercise in both males and females. There was no correlation between EIAH and EIB (p=0.21). Study 2: For the duration of the intervals, mean saturation levels remained close to resting values. Mean lung density significantly increased (p<0.05) from pre to post-exercise, with no significant changes in lung volume between scans (p=0.28). Conclusions: Our findings suggest that the swimming environment provides some protection against the development of EIAH in this population regardless of sex or presence of EIB. Furthermore, the development of pulmonary edema does occur and appears to be independent from oxyhemoglobin saturation. These results are likely attributable to the physiological response to water immersion and the horizontal body position associated with this form of exercise.

description: The continuous release of nanoparticles and nanoplastics into the marine environment necessitates the examination of their combined effects in marine organisms. Natural Organic Matter (NOM) can significantly influence the behavior of nanomaterials in the marine environment. The present study explores the effects of algal Extracellular Polymeric Substances (EPS) in reducing the combined toxic effects of three different polystyrene nanoplastics (PSNPs)— aminated (NH2-PSNPs), carboxylated (COOH-PSNPs), and plain PSNPs — and P25 titanium dioxide nanoparticles (Nano-TiO2) towards the marine alga, Chlorella sp. Two doses (0.25 and 2.5 mg/L) of nano-TiO2 mixed with the PSNPs (1 mg/L) were employed. The COOH-PSNPs with 2.5 mg/L nano-TiO2 exhibited higher growth inhibition toward algal cells. Addition of algal EPS to the mixture of NMs decreased the negative effect significantly. The mean hydrodynamic diameter increased significantly from 666 to 797 nm and 1248 to 3589 nm at concentrations 0.25 and 2.5 mg/L, respectively when the mixtures of nano-TiO2 and COOH-PSNPs were incubated with the algal EPS. In comparison to the pristine NMs, the EPS-NMs were found to significantly reduce the superoxide and hydroxyl radical production. The results were further validated with the estimation of lipid peroxidation (LPO), esterase activity, photosynthetic efficiency, and membrane permeability in the cells. The major outcomes from this study highlight the role of algal EPS in significantly reducing the toxic impact of binary mixture of NMs in marine organisms.

description: New initiatives in global health have done much to raise funds and elevate public awareness in order to launch a serious war on HIV/AIDS, tuberculosis, and malaria. Conspicuously absent from these activities, however, has been commensurate advocacy for a group of diseases that exclusively affect the poor and the powerless in rural and impoverished urban areas of developing countries. An increasing body of evidence indicates that this group of "neglected tropical diseases" may not only threaten the health of the poor as much as HIV/AIDS, tuberculosis, or malaria, but even more importantly, may have effective treatment and prevention strategies that can be delivered for less than US$1 per capita per year. Furthermore, new evidence points to substantial geographic overlap between the neglected tropical diseases and the big three, with emerging data suggesting that control of the neglected tropical diseases could actually become a powerful tool for combating HIV/AIDS, tuberculosis, and malaria. Therefore, achieving success in the global fight against HIV/AIDS, tuberculosis, and malaria may well require a concurrent attack on the neglected tropical diseases and waging a larger battle against a new 21st century "gang of four."

description: Several computational problems in phylogenetic reconstruction can be formulated as restrictions of the following general problem: given a formula in conjunctive normal form where the literals are rooted triples, is there a rooted binary tree that satisfies the formula? If the formulas do not contain disjunctions, the problem becomes the famous rooted triple consistency problem, which can be solved in polynomial time by an algorithm of Aho, Sagiv, Szymanski, and Ullman. If the clauses in the formulas are restricted to disjunctions of negated triples, Ng, Steel, and Wormald showed that the problem remains NP-complete. We systematically study the computational complexity of the problem for all such restrictions of the clauses in the input formula. For certain restricted disjunctions of triples we present an algorithm that has sub-quadratic running time and is asymptotically as fast as the fastest known algorithm for the rooted triple consistency problem. We also show that any restriction of the general rooted phylogeny problem that does not fall into our tractable class is NP-complete, using known results about the complexity of Boolean constraint satisfaction problems. Finally, we present a pebble game argument that shows that the rooted triple consistency problem (and also all generalizations studied in this paper) cannot be solved by Datalog.

description: Malaria currently kills up to 3 million people per year worldwide, most of them children in sub-Saharan Africa. Yet the disease is utterly treatable and highly preventable. Now, the international community has vowed as part of its Millennium Development Goals to make appropriate investments and interventions to bring this scourge under control. These goals, adopted by world leaders at the United Nations Millennium Assembly in September 2000, represent a commitment to reducing extreme poverty and diseases such as malaria sharply by 2015. Among other objectives, the eight development goals call for reducing by half the rates of extreme poverty and hunger by 2015 and reducing childhood mortality by two thirds and maternal mortality by three fourths relative to their 1990 levels. The goals also target the control of the great pandemic diseases — human immunodeficiency virus (HIV) and AIDS, tuberculosis, and malaria. In 2002, the high-income countries, including the United States, made a commitment to substantially increasing their aid to poor countries in order to meet these ambitious but achievable targets, though the actual flow of aid has not yet increased markedly.

description: We perform a comparative theoretical study of the data at spacelike momentum transfer for the $γ^*γ\toπ^0$ transition form factor, just reported by the Belle Collaboration, vs. those published before by BaBar, also including the older CLEO and CELLO data. Various implications for the structure of the $π^0$ distribution amplitude vis-à-vis those data are discussed and the existing theoretical predictions are classified into three distinct categories. We argue that the actual bifurcation of the data with antithetic trends is artificial and reason that the Belle data are the better option.

As a concrete model for Technicolor we use the Minimal Walking Technicolor, and this will result in the appearance of a novel fourth generation whose leptons constitute a usual weak doublet while the QCD quarks are vectorlike singlets under the weak interactions. We carry out an analysis of the mass spectra and precision measurement constraints, and find the model viable. We contrast the model with present LHC data and discuss the future prospects.

description: Gapless edge modes hosted by chirally-stacked trilayer graphene display unique features when a bulk gap is opened by applying an interlayer potential difference. We show that trilayer graphene with half-integer valley Hall conductivity leads to unbalanced edge modes at opposite zigzag boundaries, resulting in a natural valley current polarizer. This unusual characteristic is preserved in the presence of Rashba spin-orbit coupling that turns a gated trilayer graphene into a ${Z}_2$ topological insulator with an odd number of helical edge mode pairs.

description: In this paper we consider the problem of full-duplex multiple-input multiple-output (MIMO) relaying between multi-antenna source and destination nodes. The principal difficulty in implementing such a system is that, due to the limited attenuation between the relay's transmit and receive antenna arrays, the relay's outgoing signal may overwhelm its limited-dynamic-range input circuitry, making it difficult---if not impossible---to recover the desired incoming signal. While explicitly modeling transmitter/receiver dynamic-range limitations and channel estimation error, we derive tight upper and lower bounds on the end-to-end achievable rate of decode-and-forward-based full-duplex MIMO relay systems, and propose a transmission scheme based on maximization of the lower bound. The maximization requires us to (numerically) solve a nonconvex optimization problem, for which we detail a novel approach based on bisection search and gradient projection. To gain insights into system design tradeoffs, we also derive an analytic approximation to the achievable rate and numerically demonstrate its accuracy. We then study the behavior of the achievable rate as a function of signal-to-noise ratio, interference-to-noise ratio, transmitter/receiver dynamic range, number of antennas, and training length, using optimized half-duplex signaling as a baseline.

description: The dura is a rare site of involvement by marginal zone lymphoma (MZL) and the biology of dural MZL is not well understood. We performed genome-wide DNA copy number and targeted mutational analysis of 14 dural MZL to determine the genetic landscape of this entity. Monoallelic and biallelic inactivation of TNFAIP3 by mutation (n=5) or loss (n=1) was observed in 6/9 (67%) dural MZL exhibiting plasmacytic differentiation, including 3 IgG4+ cases. In contrast, activating NOTCH2 mutations were detected in 4/5 (80%) dural MZL displaying variable monocytoid morphology. Inactivating TBL1XR1 mutations were identified in all NOTCH2 mutated cases. Recurrent mutations in KLHL6 (n=2) and MLL2 (n=2) were also detected. Gains at 6p25.3 (n=2) and losses at 1p36.32 (n=3) were common chromosomal imbalances, with loss of heterozygosity (LOH) of these loci observed in a subset of cases. Translocations involving the IGH or MALT1 genes were not identified. Our results indicate genetic similarities between dural MZL and other MZL subtypes. However, recurrent and mutually exclusive genetic alterations of TNFAIP3 and NOTCH2 appear to be associated with distinct disease phenotypes in dural MZL.

description: Die Corona-Pandemie löste nach ihrem Beginn im Jahr 2020 eine weltweite Wirtschaftskrise aus. In Deutschland war – wie schon in der Finanzkrise des Jahres 2009 – Kurzarbeit ein entscheidendes Instrument, um die Folgen auf dem Arbeitsmarkt abzumildern und Arbeitsplätze zu sichern. Frauen waren in der Corona-Zeit im Vergleich zu 2009 deutlich stärker von Kurzarbeit betroffen – und damit in fast gleichem Ausmaß wie Männer. Dies liegt daran, dass von den Einschränkungen im Zuge der Lockdowns und Kontaktbeschränkungen Branchen mit einem hohen Frauenanteil – vor allem im Dienstleistungsbereich – besonders betroffen waren. Wie dieser Wochenbericht zeigt, wirkte sich die Kurzarbeit während der Corona-Pandemie kaum negativ auf die Erwerbsverläufe aus – weder bei Frauen noch bei Männern. Im Jahr 2021 waren Beschäftigte, die im Jahr zuvor von Kurzarbeit betroffen waren, nicht häufiger arbeitslos als andere Beschäftigte. Allerdings sind die Stundenlöhne von Frauen und Männern mit Kurzarbeitserfahrung im Folgejahr weniger stark gestiegen. Insgesamt erwies sich Kurzarbeit als wirksames Mittel zur Beschäftigungssicherung. Zudem wurden bestehende Ungleichheiten auf dem Arbeitsmarkt durch Kurzarbeit während der Corona-Pandemie nicht verstärkt.

description: Many studies of regional disparity in China have focused on the preferential policies received by the coastal provinces. We decomposed the location dummies in provincial growth regressions to obtain estimates of the effects of geography and policy on provincial growth rates in 1996-99. Their respective contributions in percentage points were 2.5 and 3.5 for the province-level metropolises, 0.6 and 2.3 for the northeastern provinces, 2.8 and 2.8 for the coastal provinces, 2.0 and 1.6 for the central provinces, 0 and 1.6 for the northwestern provinces, and 0.1 and 1.8 for the southwestern provinces. Because the so-called preferential policies are largely deregulation policies that have allowed coastal Chinese provinces to integrate into the international economy, it is far superior to reduce regional disparity by extending these deregulation policies to the interior provinces than by re-regulating the coastal provinces. Two additional inhibitions to income convergence are the household registration system, which makes the movement of the rural poor to prosperous areas illegal, and the monopoly state bank system that, because of its bureaucratic nature, disburses most of its funds to its large traditional customers, few of whom are located in the western provinces. Improving infrastructure to overcome geographic barriers is fundamental to increasing western growth, but increasing human capital formation (education and medical care) is also crucial because only it can come up with new better ideas to solve centuries-old problems like unbalanced growth.

description: The electron-phonon interaction (EPI) effect in single-walled carbon nanotube is investigated by the nonequilibrium Green's function approach within the Born approximation. Special attention is paid to the EPI induced Joule heating phenomenon and the thermoelectric properties in both metallic armchair (10, 10) tube and semiconductor zigzag (10, 0) tube. For Joule heat in the metallic (10, 10) tube, the theoretical results for the breakdown bias voltage is quite comparable with the experimental value. It is found that the Joule heat can be greatly enhanced by increasing the chemical potential, while the role of the temperature is not so important for Joule heat. In zigzag (10, 0) tube, the Joule heat is smaller than the armchair tube, resulting from nonzero band gap in the electron band structure. For the electronic conductance $G_{e}$ and electron thermal conductance $σ_{el}$, the EPI has important effect at higher temperature or higher chemical potential. Compared with ballistic transport, there is an opposite tendency for $G_{e}$ to decrease with increasing temperature after EPI is considered. This is due to the dominant effect of the electron phonon scattering mechanism in the electron transport in this situation. There is an interesting `electron-drag' phenomenon for the phonon thermal conductance in case of low temperature and high chemical potential, where phonons are dragged by electrons from low temperature region into high temperature region through EPI effect.

description: Translocations of the histone-lysine N-methyltransferase 2A (KMT2A) gene, formerly known as myeloid lymphoid leukemia/mixed-lineage leukemia gene, are commonly associated with high-risk de novo or therapy-associated B-cell and T-cell lymphoblastic leukemias and myeloid neoplasms. Rare B-cell non-Hodgkin lymphomas harboring KMT2A translocations have been reported, but information regarding the clinical behavior of such cases is limited. Here, we describe two extranodal diffuse large B-cell lymphomas (DLBCLs): a primary thyroid DLBCL and a large cell transformation of a splenic marginal zone lymphoma, which displayed complex karyotypes and translocations involving chromosome 11q23 targeting the KMT2A gene. The pathological and clinical characteristics of these cases are discussed in the context of previously reported lymphomas associated with different types of KMT2A genetic aberrations. In contrast to the poor clinical outcomes of patients with acute leukemias and myeloid neoplasms associated with KMT2A translocations, patients with B-cell non-Hodgkin lymphomas, exhibiting similar translocations, appear to respond well to immunochemotherapy. Our findings add to the growing list of histone methyltransferase genes deregulated in DLBCL and highlight the diversity of mechanisms, altering the function of epigenetic modifier genes in lymphomas.

description: Der Gender Care Gap, also der geschlechtsspezifische Unterschied in der Aufteilung unbezahlter Sorgearbeit wie Kinderbetreuung und Hausarbeit, ist in Deutschland vergleichsweise hoch. Frauen übernehmen deutlich mehr unbezahlte Sorgearbeit als Männer. Besonders mit der Familiengründung steigt der Gender Care Gap nachhaltig an. Zu Beginn der Corona-Pandemie vor knapp vier Jahren wurde vielfach befürchtet, dass sich der Gender Care Gap noch vergrößern könnte. Empirische Analysen zeigen, dass sich in jungen Familien zu Beginn der Pandemie in der Tat Geschlechterungleichheiten in der Sorgearbeit verschärft haben. Vor allem Mütter haben den erhöhten Betreuungsbedarf der Kinder zu Hause infolge von Kita- und Schulschließungen aufgefangen. Die Untersuchungen auf Basis von Daten des Beziehungs- und Familienpanels pairfam in diesem Wochenbericht zeigen jedoch, dass sich der Gender Care Gap inzwischen wieder auf das Niveau von vor der Pandemie zurückbewegt hat – wenngleich dieses immer noch hoch ist. Wenn die Politik Geschlechterungleichheiten auf dem Arbeitsmarkt wirksam bekämpfen will, sollte sie die ungleiche Verteilung der Sorgearbeit stärker in den Fokus nehmen und bestehende Hemmnisse für eine gleichmäßigere Aufgabenteilung abbauen. Das wäre zum Beispiel durch eine Ausweitung der Partnermonate beim Elterngeld sowie einer Reform des Ehegattensplittings und der Minijobs möglich.

description: Critics have muddled the public debate over offshore outsourcing by using the term interchangeably to refer to altogether different phenomena such as on-line purchase of services, direct foreign investment and, sometimes, all imports. We argue that clarity requires distinguishing among these various phenomena and define outsourcing explicitly as the services trade at arm's length that does not require geographical proximity of the buyer and the seller -- the so-called Mode 1 services in the WTO terminology -- conducted principally via the electronic mediums such as the telephone, fax and Internet. The definition is appropriate because this is the phenomenon that is relatively new and scary in public consciousness and has fueled the recent "outsourcing" debate. Under this definition, the total number of the U.S. jobs outsourced annually is minuscule and is expected to remain so over the next decade, even on a gross basis (i.e., without adjusting for the jobs in-sourced from the U.S.). The fears that offshore outsourcing will lead to high-value jobs being replaced by low-value jobs down the road are also argued here to be implausible in view of several qualitative arguments to the contrary. We also demonstrate that offshore outsourcing of Mode 1 services raises no new analytical issues, contrary to what many fear. Thus, it leads to gains from trade (with the standard caveats applicable to conventional trade in goods) and, in specific cases, to income-distribution effects.

description: Zunehmend setzen Staaten auf Allianzen oder Koalitionen, um gemeinsam Sanktionen gegen ein Drittland zu verhängen. Die Auswirkungen einer solchen Koordination sind jedoch unklar. Dieser Wochenbericht analysiert die Sanktionswelle gegen Russland im Jahr 2014 anhand von 400 000 Simulationen mit einem quantitativen Handelsmodell. Die Analyse zeigt, dass die multilaterale Zusammenarbeit bei den Sanktionen sowohl die Wohlfahrtsverluste im Inland verringert als auch die Wohlfahrtsverluste für Russland verstärkt hat. Innerhalb der Koalition bestehen jedoch erhebliche Ungleichheiten: In den baltischen Staaten verursachen die Russland-Sanktionen die höchsten wirtschaftlichen Kosten. Diese können aber durch eine Lastenteilung gemildert werden. Es zeigt sich auch, dass eine hypothetische Zusammenarbeit mit aufstrebenden Volkswirtschaften wie China die Wirkung von Sanktionen gegen Russland erheblich steigern kann.

description: We extend the complex-valued analytic torsion, introduced by Burghelea and Haller on closed manifolds, to compact Riemannian bordisms. We do so by considering a flat complex vector bundle over a compact Riemannian manifold, endowed with a fiberwise nondegenerate symmetric bilinear form. The Riemmanian metric and the bilinear form are used to define non-selfadjoint Laplacians acting on vector-valued smooth forms under absolute and relative boundary conditions. In the process to define the complex-valued analytic torsion, we study spectral properties associated to these generalized Laplacians. As main results, we obtain anomaly formulas for the complex-valued analytic torsion. Our reasoning takes into account that the coefficients in the heat trace asymptotic expansion associated to the boundary value problem under consideration, are locally computable. The anomaly formulas for the complex-valued Ray--Singer torsion are obtained by using the corresponding ones for the Ray--Singer metric, obtained by Bruening and Ma on manifolds with boundary, and an argument of analytic continuation. In odd dimensions, our anomaly formulas are in accord with the corresponding results of Su, without requiring the variations of the Riemannian metric and bilinear structures to be supported in the interior of the manifold.

description: Cells of the osteoblast lineage affect homing, 1, 2 number of long term repopulating hematopoietic stem cells (HSCs) 3, 4, HSC mobilization and lineage determination and B lymphopoiesis 5-8. More recently osteoblasts were implicated in pre-leukemic conditions in mice 9, 10. Yet, it has not been shown that a single genetic event taking place in osteoblasts can induce leukemogenesis. We show here that in mice, an activating mutation of β-catenin in osteoblasts alters the differentiation potential of myeloid and lymphoid progenitors leading to development of acute myeloid leukemia (AML) with common chromosomal aberrations and cell autonomous progression. Activated β- catenin stimulates expression of the Notch ligand Jagged-1 in osteoblasts. Subsequent activation of Notch signaling in HSC progenitors induces the malignant changes. Demonstrating the pathogenetic role of the Notch pathway, genetic or pharmacological inhibition of Notch signaling ameliorates AML. Nuclear accumulation and increased β-catenin signaling in osteoblasts was also identified in 38% of patients with MDS/AML. These patients showed increased Notch signaling in hematopoietic cells. These findings demonstrate that genetic alterations in osteoblasts can induce AML, identify molecular signals leading to this transformation and suggest a potential novel pharmacotherapeutic approach to AML.

description: We predict the existence of an intriguing "disorder by order" phenomenon in graphene transport where higher quality (and thus more ordered) samples, while having higher mobility at high carrier density, will manifest more strongly insulating (and thus effectively more disordered) behavior as the carrier density is lowered compared with lower quality samples (with higher disorder) which exhibit an approximate resistivity saturation phenomenon at low carrier density near the Dirac point. This predicted behavior simulating a metal-insulator transition, which we believe to have recently been observed in an experiment at Manchester University [L. A. Ponomarenko et al., Nat. Phys. 7, 958 (2011)], arises from the suppression of Coulomb disorder induced inhomogeneous puddles near the charge neutrality point in high quality graphene samples.
