description: We study the Fisher-KPP equation where the Laplacian is replaced by the generator of a Feller semigroup with power decaying kernel, an important example being the fractional Laplacian. In contrast with the case of the stan- dard Laplacian where the stable state invades the unstable one at constant speed, we prove that with fractional diffusion, generated for instance by a stable Lévy process, the front position is exponential in time. Our results provide a mathe- matically rigorous justification of numerous heuristics about this model.

Constrained multilinear detection for faster functional motif discovery

Subjects: subject: Data Structures and Algorithms (cs.DS)

description: The GRAPH MOTIF problem asks whether a given multiset of colors appears on a connected subgraph of a vertex-colored graph. The fastest known parameterized algorithm for this problem is based on a reduction to the $k$-Multilinear Detection (k-MlD) problem: the detection of multilinear terms of total degree k in polynomials presented as circuits. We revisit k-MLD and define k-CMLD, a constrained version of it which reflects GRAPH MOTIF more faithfully. We then give a fast algorithm for k-CMLD. As a result we obtain faster parameterized algorithms for GRAPH MOTIF and variants of it.

Presence, Oscillation, and the Living Cadence of Being- A Unified Theistic Naturalism Perspective
Creators: name: Patrick Carodine
Publisher: name: Unified Theistic Naturalism Publications
Year: 2025

description: The nature of existence remains a profound inquiry across disciplines. While classical materialism collapses under quantum observation, and emerging theories of simulation or illusion proliferate, a deeper living framework remains unaddressed. Unified Theistic Naturalism (UTN) proposes that existence is neither illusion nor mechanical artifact. Instead, it is the sacred, living unfolding of Presence-Being itself-expressed through the Divine cadence of Perfect Action. This paper introduces a relational model illustrating how oscillation-the subtle movement away from Divine cadence-veils Presence and gives rise to suffering. When oscillation approaches zero, the full living communion with the Divine is revealed, and paradise is naturally lived. This relational perspective offers a new foundation for understanding consciousness, cosmology, and the sacredness of existence.

description: Background

Comorbid medical diseases are highly prevalent in the geriatric population, imposing hardship on healthcare services for demented individuals. Dementia also complicates clinical care for other co-existing medical conditions. This study investigated the comorbidities associated with dementia in the elderly population aged 65 years and over in Taiwan.

Methods

We conducted a nationwide, population-based, cross-sectional survey; participants were selected by computerized random sampling from all 19 Taiwan counties between December 2011 and March 2013. After exclusion of incomplete or erroneous data, 8,456 subjects were enrolled. Of them, 6,183 were cognitively normal (control group), 1,576 had mild cognitive impairment (MCI), and 697 had dementia. We collected information about types of comorbidities (i.e., vascular risk factors, lung diseases, liver diseases, gastrointestinal diseases, and cancers), Charlson comorbidity index score, and demographic variables to compare subjects with normal cognition, MCI, and dementia.

Results

Regardless of the cognitive condition, over 60% of the individuals in each group had at least one comorbid disease. The proportion of subjects possessing at least three comorbidities was higher in those with cognitive impairment (MCI 20.9%, dementia 27.3%) than in control group (15%). Hypertension and diabetes mellitus were the most common comorbidities. The mean number of comorbidities and Charlson comorbidity index score were greater in MCI and dementia groups than in control group. Logistic regression demonstrated that the comorbidities significantly associated with MCI and dementia were cerebrovascular disease (OR 3.35, CI 2.62–4.28), cirrhosis (OR 3.29, CI 1.29–8.41), asthma (OR 1.56, CI 1.07–2.27), and diabetes mellitus (OR 1.24, CI 1.07–1.44).

Conclusion

Multiple medical comorbid diseases are common in older adults, especially in those with cognitive impairment. Cerebrovascular disease, cirrhosis, asthma, and diabetes mellitus are important contributors to cognitive deterioration in the elderly. Efforts to lower cumulative medical burden in the geriatric population may benefit cognitive function.

subject: FOS: Physical sciences

description: A numerical method to integrate the time-dependent Hartree-Fock Bogoliubov (TDHFB) equations with Gogny interaction is proposed. The feasibility of the TDHFB code is illustrated by the conservation of the energy, particle numbers, and center-of-mass in the small amplitude vibrations of oxygen 20. The TDHFB code is applied to the isoscalar quadrupole and/or isovector dipole vibrations in the linear (small amplitude) region in oxygen isotopes (masses A = 18,20,22 and 24), titanium isotopes (A = 44,50,52 and 54), neon isotope (A = 26), and magnesium isotopes (A = 24 and 34). The isoscalar quadrupole and isovector dipole strength functions are calculated from the expectation values of the isoscalar quadrupole and isovector dipole moments.

description: The Conceptual Survey of Electricity and Magnetism (CSEM) is a multiple-choice survey that contains a variety of electricity and magnetism concepts from Coulomb's law to Faraday's law at the level of introductory physics used to help inform instructors of student mastery of those concepts. Prior studies suggest that many concepts on the survey are challenging for introductory physics students and the average student scores after traditional instruction are low. The research presented here investigates the progression in student understanding on the CSEM. We compare the performance of students in introductory and advanced level physics courses to understand the evolution of student understanding of concepts covered in the CSEM after traditional lecture-based instruction. We find that on all CSEM questions on which less than 50% of the introductory physics students answered a question correctly after instruction, less than two thirds of the upper-level undergraduate students provided the correct response after traditional instruction. We also analyzed the CSEM data from graduate students for benchmarking purposes. We discuss the CSEM questions that remain challenging and the common alternative conceptions among upper-level students. The findings presented here at least partly point to the fact that traditional instruction in upper-level courses which typically focuses primarily on quantitative problem solving and incentivizes use of algorithmic approaches is not effective for helping students develop a solid understanding of these concepts. However, it is important for helping students integrate conceptual and quantitative aspects of learning in order to build a robust knowledge structure of basic concepts in electricity and magnetism.

Die Ergebnisse der Multi-Methoden-Studie ermittelten einen geringen Bekanntheitsgrad von hochschulischen Zertifikatsangeboten, die auf die Gestaltung zielgruppenspezifischer Informations- und Beratungswege hinwiesen. Darüber hinaus wurden Beratungsangebote, z.B. zur Vereinbarkeit der Angebote mit Familie und Beruf, eingefordert. Die Mehrzahl der Arbeitgebenden betrachtete die Zertifikatsangebote ausschließlich als Angebote für akademische Gesundheitsberufe und ordnete die bereits etablierten fachpraktischen Weiterbildungsangebote den beruflich qualifizierten Gesundheitsberufen zu. Aus den Ergebnissen wurden zielgruppenspezifische Assessmentinstrumente und Beratungsangebote für Gesundheitsberufe sowie für Arbeitgebende von Gesundheitsbetrieben abgeleitet, mit dem Ziel, den Bekanntheitsgrad, die Akzeptanz und erfolgreiche Teilnahme zu fördern.

description: Background

Little is known about patients with severe symptomatic aortic stenosis (AS) who receive medical management despite evaluation at a heart valve treatment center.

Objective

We identified patient characteristics associated with medical management, physician-reported reasons for selecting medical management, and patients’ perceptions of their involvement and satisfaction with treatment selection.

Methods and results

Of 454 patients evaluated for AS at 9 established heart valve treatment centers from December 12, 2013 to August 19, 2014, we included 407 with severe symptomatic AS. Information was collected using medical record review and survey of patients and treating physicians. Of 407 patients, 212 received transcatheter aortic valve replacement (TAVR), 124 received surgical aortic valve replacement (SAVR), and 71 received medical management (no SAVR/TAVR). Thirty-day predicted mortality was higher in patients receiving TAVR (8.7%) or medical management (9.8%) compared with SAVR (3.4%) (P<0.001). Physician-reported reasons for medical management included patient preference (31.0%), medical futility (19.7%), inoperability/anatomic infeasibility (11.3%), and inadequate vascular access (8.5%). Compared with patients receiving AVR, medically managed patients were less likely to report that they received enough information about the pros and cons of treatment options (P = 0.03), that their physicians involved them in treatment decisions (P<0.001), and that final decisions were the right ones (P<0.001).

Conclusions

Patient preference was the most common physician-reported reason for selecting non-invasive AS management, yet patients not undergoing AVR after valve center evaluation reported being less likely to receive sufficient education about treatment options and more likely to feel uncertain about final treatment decisions. Greater attention to shared decision making may improve the experience of care for this vulnerable group of patients.

description: "We investigate the uncertainty around stock returns at different investment horizons. Since a return is either a loss or a gain, we categorize return uncertainty into these two components. Loss uncertainty is the uncertainty surrounding negative returns, and gain uncertainty is the uncertainty surrounding any future gain. Investment opportunities can be evaluated by looking at these components.

Using data from a large panel of S&P 500 Index options with time to maturity ranging from 1 month to 12 months, we measure both types of uncertainty at different investment horizons. We also look at whether existing reduced-form option pricing models can generate similar measures.

We find that, on average, investors expect the potential for loss to decrease as the time to maturity increases. However, in the market, hedging the long-term loss potential of stocks is more expensive than hedging the short-term loss potential. Likewise, on average, investors expect the potential for gain to increase as the time to maturity increases. However, in the market, speculating on the short-term gain potential of stocks is almost as costly as speculating on the long-term gain potential."

description: "Nous étudions l’incertitude liée au rendement des actions pour différents horizons de placement. Comme le rendement est une perte ou un gain, nous classons l’incertitude liée au rendement dans l’une ou l’autre de ces deux catégories : l’incertitude liée à une perte, c’est-à-dire l’incertitude entourant les rendements négatifs, et l’incertitude liée à un gain, soit celle relative à tout gain réalisé à l’avenir. Les occasions de placement peuvent être évaluées en fonction de ces deux catégories.

Afin de mesurer les deux catégories d’incertitude pour différents horizons de placement, nous utilisons des données tirées d’un vaste échantillon d’options liées à l’indice S&P 500 dont le temps avant l’échéance va de un mois à un an. Nous vérifions également si les modèles d’évaluation des options de forme réduite qui existent déjà peuvent produire des résultats similaires.

Nous constatons que, en moyenne, plus la durée jusqu’à l’échéance est longue, plus les investisseurs s’attendent à ce que le risque de perte diminue. Cela dit, sur le marché, il coûte plus cher de couvrir le risque de perte à long terme des actions que de couvrir celui à court terme. De la même façon, nous constatons que, en moyenne, plus la durée jusqu’à l’échéance est longue, plus les investisseurs s’attendent à ce que le potentiel de gain augmente. On remarque toutefois que, sur le marché, il coûte presque tout autant de spéculer sur les gains potentiels à court terme des actions que de spéculer sur ceux à long terme."

description: Identification of early changes in Dopamine-Transporter (DaT) SPECT imaging expected in the prodromal phase of Parkinson’s disease (PD), are usually overlooked. Carriers of the G2019S LRRK2 mutation are known to be at high risk for developing PD, compared to non-carriers. In this work we aimed to study early changes in Dopamine uptake in non-manifesting PD carriers (NMC) of the G2019S LRRK2 mutation using quantitative DaT-SPECT analysis and to examine the potential for early prediction of PD. Eighty Ashkenazi-Jewish subjects were included in this study: eighteen patients with PD; thirty-one NMC and thirty-one non-manifesting non-carriers (NMNC). All subjects underwent a through clinical assessment including evaluation of motor, olfactory, affective and non-motor symptoms and DaT-SPECT imaging. A population based DaT-SPECT template was created based on the NMNC cohort, and data driven volumes-of-interest (VOIs) were defined. Comparisons between groups were performed based on VOIs and voxel-wise analysis. The striatum area of all three cohorts was segmented into four VOIs, corresponding to the right/left dorsal and ventral striatum. Significant differences in clinical measures were found between patients with PD and non-manifesting subjects with no differences between NMC and NMNC. Significantly lower uptake (p<0.001) was detected in the right and left dorsal striatum in the PD group (2.2±0.3, 2.3±0.4) compared to the NMC (4.2±0.6, 4.3±0.5) and NMNC (4.5±0.6, 4.6±0.6), and significantly (p = 0.05) lower uptake in the right dorsal striatum in the NMC group compared to NMNC. Converging results were obtained using voxel-wise analysis. Two NMC participants, who later phenoconverted into PD, demonstrated reduced uptake mainly in the dorsal striatum. No significant correlations were found between the DaT-SPECT uptake in the different VOIs and clinical and behavioral assessments in the non-manifesting groups. This study shows the clinical value of quantitative assessment of DaT-SPECT imaging and the potential for predicting PD by detection of dopamine depletion, already at the pre-symptomatic stage.

description: An effort was made to study and characterize the evolution of transient tribological wear in the presence of sliding contact. Sliding contact is often characterized experimentally via the standard ASTM D4172 four-ball test, and these tests were conducted for varying times ranging from 10 seconds to 1 hour, as well as at varying temperatures and loads. A numerical model was developed to simulate the evolution of wear in the elastohydrodynamic regime. This model uses the results of a Monte Carlo study to develop novel empirical equations for wear rate as a function of asperity height and lubricant thickness; these equations closely represented the experimental data and successfully modeled the sliding contact.

description: The objective of this research was to determine the degree of knowledge that the inhabitants of the Guadalajara Metropolitan Area (made up of the municipalities Guadalajara, Tlajomulco de Zúñiga, Tlaquepaque, Zapopan and Tonalá) had regarding tequila and the brands produced in Los Altos of Jalisco. For this, a survey consisting of five questions was designed, which was applied in the central square, center or zócalo of each municipality. The results show that the big brands, when acquired by international companies, focused their attention on capturing the consumer in international markets, since the prices of the same products that they export have been out of the pocket of those who like That drink, so it could be considered that the big brands, have left the national market a little behind, of course they did not abandon it completely, but it stopped being their main objective. Therefore, it can be concluded that the national market is the window of opportunity to join the small and still unknown producers to work together and in a grouped way, they are able to standardize a series of products that being of the same quality and same packaging, they can cover the national market, and perhaps, in the future, become a large company distributed throughout the territory and begin the export process only with national capital.

description: Methodologies to measure gender-based violence (GBV) have received inadequate attention, especially in humanitarian contexts where vulnerabilities to violence are exacerbated. This paper compares the results from individual audio computer-assisted self-administered (ACASI) survey interviews with results from participatory social mapping activities, employed with the same sample in two different post-conflict contexts. Eighty-seven internally displaced adolescent girls from the Democratic Republic of the Congo and 78 Sudanese girls living in Ethiopian refugee camps were interviewed using the two methodologies. Results revealed that the group-based qualitative method elicited narratives of violence focusing on events perpetrated by strangers or members of the community more distantly connected to girls. In contrast, ACASI interviews revealed violence predominantly perpetrated by family members and intimate partners. These findings suggest that group-based methods of information gathering frequently used in the field may be more susceptible to socially accepted narratives. Specifically, our findings suggest group-based methods may produce results showing that sexual violence perpetrated by strangers (e.g., from armed groups in the conflict) is more prevalent than violence perpetrated by family and intimate partners. To the extent this finding is true, it may lead to a skewed perception that adolescent GBV involving strangers is a more pressing issue than intimate partner and family-based sexual violence, when in fact, both are of great concern.

description: In South Korea TMDLs are now calculated in the administration boundaries (similar to counties in the U.S.) along the main rivers by multiplying a calculated reference flow times the water quality concentration of different parameters. To model this practice, a hydrologic system was implemented which simulates daily stream flows at the 36 main gauging stations along the streams within the Geum River basin. This computer system uses the DAWAST runoff model to calculate return flows from paddy fields, domestic and industrial uses, and was verified using two years of observed data measured every eight days. This computer system has several modules for estimating daily demands from: paddies, domestic water uses, and industrial water uses. The computer system also simulates daily water storage in reservoirs, and calculates reference flows and total loads. A presentation of the computer system and it application to the Geum River will be presented.

description: Viele Hochschulen führen in unterschiedlichen Abständen Befragungen unter den Teilnehmenden der nachberuflichen wissenschaftlichen Weiterbildung durch, die Einblicke in Studienmotive und Studierverhalten Älterer an den jeweiligen Standorten bieten. Es fehlen jedoch einheitliche, bundesweite Daten zum Studium Älterer. Denn die jeweiligen Ergebnisse sind aufgrund unterschiedlicher Fragestellungen und Frageformen zumeist nicht miteinander vergleichbar. Auch die jährliche bundesweite Zählung von Gasthörenden erfasst nicht alle älteren Studierenden, da nicht alle Teilnehmenden an nachberuflicher wissenschaftlicher Weiterbildung unter diesem Status geführt werden. Um diese Lücke zu schließen, wurde in der Bundesarbeitsgemeinschaft Wissenschaftliche Weiterbildung für Ältere (BAG WiWA) ein Fragebogen entwickelt, in dem Motivlagen, Fächerpräferenzen, Formen des Studierens und soziodemographische Daten erfasst werden können. Im vorliegenden Beitrag werden einige zentrale Ergebnisse von Teilnehmendenbefragungen älterer Studierender aus drei Hochschulen vorgestellt, bei denen der Fragebogen erstmalig zum Einsatz kam. Die Ergebnisse weisen eine hohe Übereinstimmung im Hinblick auf Fächerpräferenzen und Motivlagen auf und zeigen, dass soziodemographische Daten wie Bildung und Geschlecht in einem Zusammenhang mit den Teilnahmemotiven und den subjektiven Gewinnen stehen. Darüber hinaus zeigt sich, dass auch die Angebotsstruktur einer Institution Einfluss auf das Antwortverhalten der Befragten hat.

description: We study the causal effect of mortgage rate changes on consumer spending, debt repayment and defaults during an expansionary and a contractionary monetary policy episode in Canada. We find asymmetric responses of consumer durable spending, deleveraging and defaults. These findings help us to understand household sector response to interest rate changes.

description: Nous étudions l’effet de causalité des variations des taux hypothécaires sur les dépenses des consommateurs, le remboursement de leurs dettes et leurs défauts de paiement durant des périodes où la politique monétaire est soit expansionniste soit restrictive au Canada. L’identification de l’effet de causalité est facilitée par le fait que les prêts hypothécaires à taux fixe à court terme (le produit le plus populaire du marché hypothécaire canadien) doivent être renouvelés à des intervalles préétablis selon les taux d’intérêt en vigueur sur le marché.

description: Marine robots, particularly Unmanned Surface Vessels (USVs), have gained considerable attention for their diverse applications in maritime tasks, including search and rescue, environmental monitoring, and maritime security. This paper presents the design and implementation of a USV named marine$\mathcal{X}$. The hardware components of marine$\mathcal{X}$ are meticulously developed to ensure robustness, efficiency, and adaptability to varying environmental conditions. Furthermore, the integration of a vision-based object tracking algorithm empowers marine$\mathcal{X}$ to autonomously track and monitor specific objects on the water surface. The control system utilizes PID control, enabling precise navigation of marine$\mathcal{X}$ while maintaining a desired course and distance to the target object. To assess the performance of marine$\mathcal{X}$, comprehensive testing is conducted, encompassing simulation, trials in the marine pool, and real-world tests in the open sea. The successful outcomes of these tests demonstrate the USV's capabilities in achieving real-time object tracking, showcasing its potential for various applications in maritime operations.

description: In a federation, a cyclically-sensitive central government budget shifts tax revenues and spending programs benefits from states experiencing economic expansions to those enduring contractions. In this way, central governments make citizens better off by using fiscal policy to pool income risk across economically-diverse regions. Correlations of Canadian provincial GDPs confirm that provincial economies experience diverse business cycles. Interprovincial price adjustments and population migrations respond to business cycles; however, non-discretionary fiscal policy remains the only viable policy tool for achieving stabilization. I identify automatically stabilizing budget categories and the size of fiscal insurance they provide. Notably, provinces with relatively high incomes enjoy the benefits of fiscal insurance yielded by the federal budget more so than other provinces. Generating larger amounts of federal fiscal insurance, requires an increase in the sensitivity to those budget components behaving most effectively as both automatic stabilizers and fiscal insurance providers. This thesis identifies those budget components.

Literatura Venezolana de la primera década del siglo XXI : la narrativa de Eduardo Sánchez Rugeles
Creators: name: Barrios, Belkis
Publisher: name: University of British Columbia
Year: 2011

description: This thesis studies the representational forms of the sociopolitical “decadence” in Twenty-First century Venezuela in the works of emergent writer Eduardo Sánchez Rugeles, author of Blue Label/Etiqueta Azul (2010) and Transilvania Unplugged (2011). The core argument states that Sánchez Rugeles’ postmodern/postautonomous aesthetics deliberately blend commercial mass culture expressions into the literary work, in order to represent Venezuelan city dweller’s “everyday” present life. The destiny of the characters represented by Sánchez Rugeles is marked by an unprecedented reality: the Diaspora of middle-class and affluent Venezuelans, triggered during Hugo Chávez’s presidency due to social fractures, economic difficulties and fears to the “ghosts” of a totalitarian, communist regime. In a twofold metafictional gesture, the writer constructs a narrative “present” that mirrors the fragmented texts and images transmitted through different mass media and virtual channels, without considering boundaries of temporality or spatiality. However, while Sánchez Rugeles’ literary work appears to “integrate” itself into the consumer society’s commercial manifestations, it also proves effective in its questioning of the autonomous state of art, the fragility of historical memory, the glorification of heroes of the past and the ideological conflicts of the present in which it is inscribed.
