description: In the last decades a liberalization of the electric market has started; prices are now determined on the basis of contracts on regular markets and their behaviour is mainly driven by usual supply and demand forces. A large body of literature has been developed in order to analyze and forecast their evolution: it includes works with different aims and methodologies depending on the temporal horizon being studied. In this survey we depict the actual state of the art focusing only on the recent papers oriented to the determination of trends in electricity spot prices and to the forecast of these prices in the short run. Structural methods of analysis, which result appropriate for the determination of forward and future values are left behind. Studies have been divided into three broad classes: Autoregressive models, Regime switching models, Volatility models. Six fundamental points arise: the peculiarities of electricity market, the complex statistical properties of prices, the lack of economic foundations of statistical models used for price analysis, the primacy of uniequational approaches, the crucial role played by demand and supply in prices determination, the lack of clearcut evidence in favour of a specific framework of analysis. To take into account the previous stylized issues, we propose the adoption of a methodological framework not yet used to model and forecast electricity prices: a time varying parameters Dynamic Factor Model (DFM). Such an eclectic approach, introduced in the late ‘70s for macroeconomic analysis, enables the identification of the unobservable dynamics of demand and supply driving electricity prices, the coexistence of short term and long term determinants, the creation of forecasts on future trends. Moreover, we have the possibility of simulating the impact that mismatches between demand and supply have over the price variable. This way it is possible to evaluate whether congestions in the network (eventually leading black out phenomena) trigger price reactions that can be considered as warning mechanisms.

description: I review here the history of bottom quark cross section measurements and theoretical predictions. Starting form the early days of UA1, and going through the sequence of the large excesses reported during run 0 and I at the Tevatron by CDF and D0, I summarize how both data and theory have evolved in time, thanks to improved experimental techniques, more data, and improved control over the main ingredients of the theoretical calculations. I conclude with the discussion of the preliminary data from run II, which appear to finally give a satisfactory picture of the data vs theory comparison.

description: Gluing two manifolds M_1 and M_2 with a common boundary S yields a closed manifold M. Extending to formal linear combinations x=Sum_i(a_i M_i) yields a sesquilinear pairing p= with values in (formal linear combinations of) closed manifolds. Topological quantum field theory (TQFT) represents this universal pairing p onto a finite dimensional quotient pairing q with values in C which in physically motivated cases is positive definite. To see if such a "unitary" TQFT can potentially detect any nontrivial x, we ask if is non-zero whenever x is non-zero. If this is the case, we call the pairing p positive. The question arises for each dimension d=0,1,2,.... We find p(d) positive for d=0,1, and 2 and not positive for d=4. We conjecture that p(3) is also positive. Similar questions may be phrased for (manifold, submanifold) pairs and manifolds with other additional structure. The results in dimension 4 imply that unitary TQFTs cannot distinguish homotopy equivalent simply connected 4-manifolds, nor can they distinguish smoothly s-cobordant 4-manifolds. This may illuminate the difficulties that have been met by several authors in their attempts to formulate unitary TQFTs for d=3+1. There is a further physical implication of this paper. Whereas 3-dimensional Chern-Simons theory appears to be well-encoded within 2-dimensional quantum physics, eg in the fractional quantum Hall effect, Donaldson-Seiberg-Witten theory cannot be captured by a 3-dimensional quantum system. The positivity of the physical Hilbert spaces means they cannot see null vectors of the universal pairing; such vectors must map to zero.

Preparation Uncertainty Implies Measurement Uncertainty in a Class of Generalized Probabilistic Theories

description: In quantum theory, it is known for a pair of noncommutative observables that there is no state on which they take simultaneously definite values, and that there is no joint measurement of them. They are called preparation uncertainty and measurement uncertainty respectively, and research has unveiled that they are not independent from but related with each other in a quantitative way. This study aims to reveal whether similar relations to quantum ones hold also in generalized probabilistic theories (GPTs). In particular, a certain class of GPTs is considered which can be characterized by transitivity and self-duality and regarded as extensions of quantum theory. It is proved that there are close connections expressed quantitatively between two types of uncertainty on a pair observables also in those theories: if preparation uncertainty exists, then measurement uncertainty also exists, and they are described by similar inequalities. Our results manifest that their correspondences are not specific to quantum theory but more universal ones.

description: Following the liberalization reforms of the late 80s and early 90s, several emerging market economies have experienced large and persistent trade deficits. This paper focuses on the Argentine experience, examining the extent to which trade imbalances in the 1990s resulted from income and relative price movements, as well as from shifts in foreign trade elasticities associated with structural changes. New estimates of export and import equations are presented using a broader set of variables than previous studies and distinguishing between intra and extra MERCOSUR trade. We find that considerable export sensitivity to world commodity prices, domestic absorption, and economic activity in Brazil, combined with a high income elasticity of imports, are key determinants of Argentina’s trade balance.

description: This paper investigates the monetary interdependence and the money-income relationship between countries under a pegged and a floating exchange rate system during the same time period (1979-1997). The relationship is tested between three ERM countries, France, Germany and Holland, and also between these countries and the United States. The ERM countries have a pegged exchange rate between themselves, and the rate between these countries and the United States is freely floating. The empirical tests are conducted by means of the Johansen multivariate cointegration method and the error correction model. Among the ERM countries, international transmission of monetary policy is found in almost all directions. This may provide evidence against the theory of German domination of the EMU. In the second set of tests, the United States money is found to affect all three European incomes but not vice versa.

Are the Poor Protected from Budget Cuts? Evidence for Argentina

description: Macroeconomic adjustment programs often emphasize the need to protect social spending from cuts, and to protect pro-poor spending in particular. But does this happen in practice during fiscal contractions? The paper presents evidence for Argentina. Using aggregate time series data the paper first finds that social spending was not protected historically, although more "pro-poor" social spending was no more vulnerable. Turning next to new data for an externally-financed workfare scheme introduced in response to a macro crisis, the paper finds that this program was far better targeted than other social spending. However, it appears that the program still had to assure that a small but relatively well-protected share of its benefits went to the non-poor. This appears to be a political economy constraint.

description: New 2007-13 planning framework of the EU keeps using economic criteria (GDP) to identify those regions requiring priority attention (convergence objective). Although these criteria are useful for the overall Regional Policy, nevertheless it might result some planning failures of the strategies of rural development. This work focuses in evaluating possible failures of the Rural Development Programmes. For this purpose, a wide range of member Estates and Regions has been selected and two analysis have been applied: first, the coherence analysis (in relation to the economic, social and environmental situation of territories); and second, the conflict (among the rural territories development objectives) analysis. As result of this evaluation, a typology of the analysed Rural Development Programmes will be shown, which identifies different cases of failures. This work concludes that the use of methodological criteria in Regional Policy complementing to the Efficiency criteria might improve the territorial cohesion process and reduce some of the analysed failures in rural areas.

The rationale of indepth case study analysis as an essential complement to formal evaluation techniques is illustrated with comparative studies of employment impacts of Pillar Two policies in 6 rural areas in different EU member states. Recommendations arising include accelerated shifts from commodity support to measures strengthening non-farm sectors of the rural economy, whilst retaining support for farming adaptation; use of clear structural indicators and local expertise to determine priorities; and integration of Pillar Two policies with other measures in consistent, spatially nested Action Plans for Rural Development which set targets for improvement in economic and demographic performance.

description: Vascular malformations (VMs) are dysplastic abnormalities of vascular channels, differing from vascular tumors by their slow growth. Arteriovenous malformations (AVMs) arise between weeks 4-10 of intrauterine life, with a prevalence of 1 in 100,000 among Caucasians. Common in the head, neck, and hands, AVMs may be asymptomatic or cause symptoms like pain, deformity, and disability. Treatments range from conservative management to amputation in severe cases. A 28-year-old male with finger trauma was found to have a vascular tumor, later diagnosed as an arteriovenous malformation, surgically removed and confirmed by histopathology. Angiography is the gold standard for diagnosing AVMs, though imaging and physical exams are often sufficient. Conservative management is preferred for minor symptoms, with surgery reserved for severe cases. Surgical intervention carries risks, especially for diffuse lesions. Treatment for hand AVMs is challenging, requiring specialized expertise due to the hand’s complex anatomy.

We outline two different theoretical models for the preparation and collection of either single-mode or multi-mode PDC light (defined by, for instance, multi-mode fibers or apertures, corresponding to bucket detection). Moreover, we define the mode-matching collection efficiency, important for realizing a single-photon source based on PDC output into a well-defined single spatial mode. We also define a multimode collection efficiency that is useful for single-photon detector calibration applications.

title: Climate model systematic biases in the Maritime Continent: mean state, interannual variability and teleconnections
Creators: name: Toh, Ying Ying
Publisher: name: University of Reading
Year: 2019

description: Societies in the Maritime Continent depend on monsoon rainfall for their water supply. Large spatio-temporal variability of the rains has a significant socio-economic impact and affects the global circulation. However, the Maritime Continent remains a major modelling challenge. In this thesis, the fidelity of the fifth Coupled Model Intercomparison Project (CMIP5) models at simulating mean climate and its variability over the Maritime Continent is assessed. We find that model horizontal resolution is not a good indicator of performance in atmosphereonly models. Instead, a given model’s local Maritime Continent biases are somewhat related to biases in the local Hadley circulation and global monsoon. Cluster analysis on Maritime Continent annual cycle precipitation results in two distinct clusters: Cluster I models are able to capture both the winter monsoon and summer monsoon shift, whereas Cluster II models simulate weaker seasonal migration than observed. A model’s Maritime Continent climatological mean-state precipitation is shown to be negatively correlated with sea-surface temperature (SST) biases in central tropical Pacific Ocean (CTPO) and western tropical Indian Ocean (WTIO) regions in coupled CMIP5 models. On interannual timescales, the El Nino-Southern Oscillation (ENSO) and Indian Ocean ˜ Dipole (IOD) teleconnections to Maritime Continent precipitation are well simulated by both uncoupled and coupled CMIP5 models. However, the spatial pattern of these teleconnections is not well captured, especially in coupled models. Idealized Maritime Continent SST-perturbation experiments are performed using the HadGEM3-GA6 atmospheric model in the CPTO and WTIO regions. These result in remote responses of Maritime Continent mean precipitation, somewhat comparable with the signals related to biases found in the CMIP5 coupled models. This suggests that remote Indo-Pacific SST biases in the CMIP5 coupled models could plausibly cause the precipitation biases over the Maritime Continent, and thus highlights the importance of reducing these biases to improve Maritime Continent mean state and climate variability.

description: The paper deals with the political economy determinants of EU agri-environmental measures (AEMs) applied by 59 regional/country units, during the 2001-2004 period. Five different groups of determinants, spanning from positive and negative externalities to political institutions, are highlighted and tested using an econometric model. The main results suggest that AEMs implementation is mostly affected by the strength of farm lobbies, political institutions and the demand for positive externalities. On the contrary, AEMs do not seem implemented by the willingness to address negative externalities.

description: Kartagener syndrome (KS) is a rare congenital disorder, characterized by sinusitis, bronchiectasis and situs inversus. Lung transplantation is an effective treatment for end-stage lung failure, but dextrocardia and differences between hilar structures and pulmonary lobes require adjustments to conventional surgical technique.


We present a case of a double-lung transplant without extracorporeal oxygenation in a 48-year-old male patient with KS. Through a Clamshell incision, right-left rotation was identified. To provide an end-to-end arterial and bronchial anastomosis, longer donor PA’s and right main bronchus were preserved. Wedge resection of right inferior lobe was unnecessary and there was no left residual cardiac chamber.


Patient was discharged 32 days after surgery without complications.


Despite being anatomically challenging, lung transplant was done successfully without the need for plastic maneuvers or extracorporeal circulation. This reinforces the idea that it should be an option in end-stage lung disease.

 Haplothrips pictipes Bagnall, 1919: 273.
 Described originally from Indonesia (Sumatra) and India (Talimbaramta) and recorded on diseased pepper berries, the feeding habits of this species are not clear. Mound and Tree (2019) recorded the species living on the leaves and flowers of live plants, various weeds, dried fruits and dead branches. In this study, 38 females and 19 males have been beaten from weeds, bamboo leaves and pine tree with isolated individuals from southwest of China, including Tibet, Sichuan, Jiangxi and Yunnan. Some males have armed fore tarsi and somewhat enlarged fore femora, and the species may be a predator rather than a fungus-feeder. It is easily distinguished from the other three Mesandrothrips species from China in having the pronotal am setae well developed (Fig. 4).

description: We study the large-scale stellar and gaseous kinematics of the E4 galaxy NGC2974, based on panoramic integral-field data obtained with SAURON. We quantify the velocity fields with Fourier methods (kinemetry), and show that the large-scale kinematics is largely consistent with axisymmetry. We construct general axisymmetric dynamical models for the stellar motions using Schwarzschild's orbit-superposition method, and compare the inferred inclination and mass-to-light ratio with the values obtained by modelling the gas kinematics. Both approaches give consistent results. However we find that the stellar models provide fairly weak constraints on the inclination. The intrinsic orbital distribution of NGC2974, which we infer from our model, is characterised by a large-scale stellar component of high angular momentum. We create semi-analytic test models, resembling NGC2974, to study the ability of Schwarzschild's modelling technique to recover the given input parameters (mass-to-light ratio and inclination) and the distribution function. We also test the influence of a limited spatial coverage on the recovery of the distribution function (i.e. the orbital structure). We find that the models can accurately recover the input mass-to-light ratio, but we confirm that even with perfect input kinematics the inclination is only marginally constrained. This suggests a possible degeneracy in the determination of the inclination, but further investigations are needed to clarify this issue. For a given potential, we find that the analytic distribution function of our test model is well recovered by the three-integral model within the spatial region constrained by integral-field kinematics.

Predicting source code changes by mining revision history
Creators: name: Ying, Annie Tsui Tsui
Publisher: name: University of British Columbia
Year: 2009

description: Software developers are often faced with modification tasks that involve source which is spread across a code base. Some dependencies between source, such as the dependencies between platform dependent fragments, cannot be determined by existing static and dynamic analyses. To help developers identify relevant source code during a modification task, we have developed an approach that applies data mining techniques to determine change patterns—files that were changed together frequently in the past—from the revision history of the code base. Our hypothesis is that the change patterns can be used to recommend potentially relevant source code to a developer performing a modification task. We show that this approach can reveal valuable dependencies by applying the approach to the Eclipse and Mozilla open source projects, and by evaluating the predictability and interestingness of the recommendations produced.

description: The paper discusses an ex ante evaluation of the derogation on the Nitrates Directive for Flanders, Belgium, which is a case of intensive but highly productive livestock areas. The aim is to develop an accurate simulation model to detect small differences in manure surpluses caused by changes of manure production and/or utilization. The system of models consists of various modules to fine tune the calculations of manure production, fertilizing behaviour and manure allocation and disposal on and off farm. The results show that derogation may cause the existing manure surpluses to expire, if only nitrogen limits are considered and no transactions costs are taken into account. When also phosphate fertilization limits are considered, the increase in manuring possibilities is much lower than expected. Ongoing research focuses on the marginal shifts in manure surplus at farm level and possible effects of transactions costs.
Evidence for collisional depolarization in the MgH lines of the second solar spectrum

description: Analysis of the Hanle effect in solar molecular lines allows us to obtain empirical information on hidden, mixed-polarity magnetic fields at subresolution scales in the (granular) upflowing regions of the `quiet' solar photosphere. Here we report that collisions seem to be very efficient in depolarizing the rotational levels of MgH lines. This has the interesting consequence that in the upflowing regions of the quiet solar photosphere the strength of the hidden magnetic field cannot be sensibly larger than 10 G, assuming the simplest case of a single valued microturbulent field that fills the entire upflowing photospheric volume. Alternatively, an equally good theoretical fit to the observed scattering polarization amplitudes can be achieved by assuming that the rate of depolarizing collisions is an order of magnitude smaller than in the previous collisionally dominated case, but then the required strength of the hidden field in the upflowing regions turns out to be unrealistically high. These constraints reinforce our previously obtained conclusion that there is a vast amount of hidden magnetic energy and unsigned magnetic flux localized in the (intergranular) downflowing regions of the quiet solar photosphere.

description: An agronomic crop growth model—the Decision Support System for Agro-Technology Transfer—and a constant relative risk aversion utility function are used to examine corn irrigation strategies in Mitchell County, Georgia. Precipitation contracts are designed to help farmers manage risk. Three conclusions originate from the findings. First, the optimal irrigation strategy can greatly increase producers’ certainty-equivalent revenue. Second, changes in water pricing policy would have a limited impact on the amount of water used. And third, across levels of risk preference, the precipitation contracts are not effective in increasing certainty-equivalent revenue or reducing cumulative water use.

description: Introduction: Pancoast tumors encompass any tumor located on the lung apex, extending into structures in the thoracic inlet and, often, leading to the characteristic clinical syndrome. The main goal of this study is to analyze the response to multimodal treatment and outcome of patients with Pancoast tumors.

Materials and Methods: We performed a retrospective cohort single center study of patients with superior sulcus nonsmall cell lung carcinomas who underwent surgery between January of 2011 and February of 2022.

Results: A total of ten patients were considered, 80,0% were male with a mean age of 53,6 (±6,6) years. At diagnosis, two tumors were stage II and eight were stage III. Histopathology revealed eight were adenocarcinomas and two were sarcomatoid carcinomas. All patients underwent neoadjuvant treatment before surgery. Nine patients received lung lobectomy, with en bloc resection comprising, predominantly, the chest wall (80,0%) and brachial plexus (30,0%). In one patient, surgery was aborted. Surgical histopathology showed free surgical margins were achieved in eight patients (80,0%). Two patients achieved full tumoral remission (ypT0N0, 22,2%), two tumors were stage I (22,2%), two were stage II (22,2%), two were stage III (22,2%) and one tumor was stage IV (11,1%). Mean disease-free survival was 83,9 (CI95% 42,1-125,8) months. 3-month disease-free survival rate was 88,9% and 1-year and 5-year disease-free survival rates were 63,5%. After the first-year follow-up, there was no evidence of disease progression. Mean overall survival was 115,7 (CI95% 89,3-142,1) months. At 3-month, 1-year and 5-years, overall survival was 88,9%.

Conclusion: Although considering the small sample of patients, the survival of Pancoast tumors in our institution exhibits a positive outcome, when compared to current literature, Significant improvements have been reported recently, in understanding the nature of Pancoast tumors, emphasizing the importance of a multidisciplinary approach but still, further research is required.

description: Objectives: Effective revascularization is the cornerstone of limb salvage in chronic limb threatening ischemia. In recent years, less invasive endovascular revascularization techniques have supplanted surgical bypass as the primary mode of revascularization. The real impact of this transition is being increasingly questioned. This study aims to evaluate the endovascular evolution, and how it impacted the amputation rates nationwide since de beginning of the century.

Methods: Patients admitted to Portuguese public hospitals with peripheral arterial disease between 2000 and 2015 were selected. Of these, patients that underwent to limb revascularization and/ or limb amputation were evaluated. The information was obtained through the National Health Service administrative database. Three time periods (2000-2004, 2005-2009, 2010-2015) were considered to evaluate the evolution in amputation rates and type of revascularization.

Results: The global number of revascularization episodes consistently increased along the 15 analyzed years. There were 25252 admissions for revascularization (55.1% open and 44.9% endovascular). The mean incidence of endovascular procedures significantly increased 5.8 times (p<0.01), and open surgery increased 1.3 times (p<0.01) when comparing the three time periods. 34633 limb amputations (65.3% major vs 34.7% minor) were realized along 15 years. The mean incidence of lower limb amputations increased by 1.5 times thanks to minor amputation, whose mean incidence increased two-fold while with the incidence of major amputations remained stable. Additionally, mean hospital mortality associated with revascularization episodes decreased from 10.6% to 8.2% (p<0.01), on 15-year follow-up.

Conclusions: There was a significative increase in revascularization episodes over the 15 years, suggesting better access to health services and/or better diagnostic accuracy. Endovascular procedures were the most practiced. This was along with an increase in the minor limb amputation, a stabilization in major amputations incidence. This nationwide study adds to the increasing body of knowledge in the ever-pertinent discussion of revascularization types and their benefits.

description: Because of the decline of the Ogallala Aquifer, water districts, regional water managers, and state water officers are becoming increasingly interested in conservation policies. This study evaluates both short-term and long-term water rights buyout policies. This research develops dynamic production functions for the major crops in the Texas Panhandle. The production functions are incorporated into optimal temporal allocation models that project annual producer behavior, crop choices, water use, and aquifer declines over 60 years. Results suggest that long-term buyouts may be more economically efficient than short-term buyouts.

description: The four papers presented at this invited session examine various ways that economic analysis can be used to examine issues of water conservation strategies and policies. Three of the four are focused on water issues in Texas, and one examines a private insurance contract scheme for irrigation scheduling using Georgia weather and water data. All four papers are well written and interesting, but all four illustrated the limits of conventional economic analysis in its ability to shed light on public policy. This is particularly the case in the heavy reliance on economic efficiency analysis that is employed in the papers.

description: This paper introduces the Bateson Game, a novel game-theoretic framework based on Gregory Bateson's concept of the double bind. We model double binds as two-player signaling games with frame ambiguity, in which all possible receiver responses lead to dissonant or negative outcomes due to contradictory interpretive frames (literal vs. meta). The model demonstrates how power is exerted through control of the interpretive context. We present both a formal definition and a simulation of adaptive agents under strategic ambiguity.

description: Angular distributions for production of the $Θ^+$ pentaquark are calculated for the collisions of polarized protons with polarized target protons. We compare calculations based on different assumptions concerning spin and parity ($J=1/2^\pm,3/2^\pm$) of the $Θ^+$ state. For a wide class of interactions the spin correlation parameters describing the asymmetric angular distributions are calculated up to 250 MeV above production threshold. The deviations from the near threshold behavior are investigated.

description: Using state-level data from the Behavioral Risk Factor Surveillance System, we investigate the effects of household food-away-from-home and food-at-home expenditures on overweight rates, obesity rates, and combined rates. Our random effects model estimates suggest that food-away-from-home expenditures are positively related to obesity and combined rates, while food-at-home expenditures are negatively related to obesity and combined rates. However, the magnitudes of these effects, while statistically significant, are relatively small. Both food-at-home and food-away-from-home expenditures do not significantly influence overweight rates.
