title: Relevant components in critical random Boolean networks
Creators: name: Kaufman, Viktor

Publisher: name: IOP Publishing
Year: 2024

description: Random Boolean networks (RBNs) were introduced in 1969 by Kauffman as a model for gene regulation. By combining analytical arguments and efficient numerical simulations, we evaluate the properties of relevant components of critical RBNs independently of update scheme. As known from previous study, the number of relevant components grows logarithmically with network size. We find that in most networks all relevant nodes with more than one relevant input sit in the same component, while all other relevant components are simple loops. As the proportion of nonfrozen nodes with two relevant inputs increases, the number of relevant components decreases and the size and complexity of the largest complex component grows. We evaluate the probability distribution of different types of complex components in an ensemble of networks and confirm that it becomes independent of network size in the limit of large network size. In this limit, we determine analytically the frequencies of occurrence of complex components with different topologies.

description: Abstract: Introduction: Glycated haemoglobin A1c (HbA1c) is the established standard measurement for assessment of glycaemic control in people with diabetes. Here we report on a meta-analysis of real-world observational studies on the impact of flash continuous glucose monitoring on glycaemic control as measured by HbA1c. Methods: A total of 271 studies were identified in our search, of which 29 contained data reporting changes in HbA1c over periods from 1 to 24 months that could be used in a statistical analysis. Our meta-analysis focuses on observed change in HbA1c at either 2, 3 or 4 months, in adult or paediatric subjects, as well as a longitudinal analysis up to 12 months in adult subjects. These data were drawn from 25 of the studies identified in our initial search. These reported HbA1c data up to 12 months in a total of 1723 participants with type 1 diabetes (T1D) or type 2 diabetes (T2D) using the FreeStyle Libre® flash glucose monitoring system. Results: Overall mean change in laboratory HbA1c across study subjects at 2–4 months was − 0.55% (95% CI − 0.70, − 0.39). Amongst the 1023 adults, mean change in HbA1c was − 0.56% (95% CI − 0.76, − 0.36); for the 447 children and adolescents, mean change in HbA1c was − 0.54% (95% CI − 0.84, − 0.23). Based on regression analysis, the degree of change in HbA1c correlated with the initial HbA1c of the study population. A longitudinal analysis in adult subjects (n = 1276) shows that HbA1c fell within the first 2 months and changes were sustained up to 12 months. No significant differences were detected between T1D and T2D. Conclusion: The meta-analysis reported here confirms that starting the FreeStyle Libre system as part of diabetes care results in a significant and sustained reduction in HbA1c for adults and children with T1D and for adults with T2D.

description: Haptic sensory feedback has been shown to complement the visual and auditory senses, improve user performance and provide a greater sense of togetherness in collaborative and interactive virtual environments. However, we are faced with numerous challenges when deploying these systems over the present day Internet. The most significant of these challenges are the network performance limitations of the Wide Area Networks. In this paper, we offer a structured examination of the current challenges in the deployment of haptic-based distributed systems by analyzing the recent advances in the understanding of these challenges and the progress that has been made to overcome them.

description: A new series of regioselective dispiropyrrolidine analogs via efficient one-pot four-component tandem reaction has been discovered. The reaction was carried out in the presence of four common reactants and magnesium silicate nanoparticles (NPs) in ethanol under microwave irradiation. The reaction proceeds rapidly and can be completed within 60–90 min. This methodology offers several significant advantages such as high yield, mild catalyst, and easy to perform. The synthesized compound was further screened for antibacterial and antiproliferative activities. The results showed that compound 5c and 5a were potent antibacterials against Gram-positive and Gram-negative bacteria. Further, 5a showed best antiproliferative activity against tested cell lines.

 Type species. Paraleiopus macrochelis Brum, 1978 (monotypy).
 Diagnosis. Modified according to Guţu (1996a).
Without spiniform apophyses on carapace, pereon and pleon. Ocular lobes present, without visual elements. Pleonites with one pair of lateral plumose setae and dorsolateral simple setae. Antenna with four–articulated peduncle; last article longer than others; squama present, well developed. Mandibles with three–articulated palp. Labial palp with one terminal and one subterminal long spiniform seta. Cheliped and pereopod 1 with exopodite. Pereopod 1 without coxal spine and dactylus with one long bifid seta near unguis. Pereopods 2–5 dactylus with attenuated elongate “seta–like” unguis. Pereopod 6 with normal unguis.
 Remarks. Paraleiopus is a monotypic genus found in the SW Atlantic off Brazil. The genus Paraleiopus was originally placed in the family Leiopidae Lang, 1970 (Silva Brum, 1978); however, Băcescu and Absalao (1985), realizing its affinity to Hemikalliapseudes cavooreni placed it in the family Kalliapseudidae as a subgenus of the genus Hemikalliapseudes. Guţu (1996) recognized that it exhibited enough distinctive characters to warrant full generic rank.

description: Li abundances are derived for a sample of bulgelike stars with isochronal ages of 10-11 Gyr. These stars have orbits with pericentric distances, Rp, as small as 2-3 kpc and Zmax < 1 kpc. The sample comprises G and K dwarf stars in the metallicity range -0.80 4.5 Gyr) within the present metallicity range are available. M67 (4.7 Gyr) and NGC 188 (6 Gyr) are the oldest studied metal-rich open clusters with late-type stars. Li abundances have also been studied for few samples of old metal-rich field stars. In the present work a high dispersion in Li abundances is found for bulgelike stars for all the metallicity range, comparable with values in M67. The role of metallicity and age on a Li depletion pattern is discussed. The possible connection between Li depletion and oxygen abundance due to atmospheric opacity effects is investigated.

description: We present a novel infrared spectral energy distribution (SED) modeling methodology that uses likelihood-based weighting of the model fitting results to construct probabilistic H-R diagrams (pHRD) for X-ray identified, intermediate-mass (2-8 $M_{\odot}$), pre-main sequence young stellar populations. This methodology is designed specifically for application to young stellar populations suffering strong, differential extinction ($ΔA_V > 10$ mag), typical of Galactic massive star-forming regions. We pilot this technique in the Carina Nebula Complex (CNC) by modeling the 1-8 $μ$m SEDs of 2269 likely stellar members that exhibit no excess emission from circumstellar dust disks at 4.5 $μ$m or shorter wavelengths. A subset of ${\sim}100$ intermediate-mass stars in the lightly-obscured Trumpler 14 and 16 clusters have available spectroscopic $T_{\rm eff}$, measured from the Gaia-ESO survey. We correctly identify the stellar temperature in 70% of cases, and the aggregate pHRD for all sources returns the same peak in the stellar age distribution as obtained using the spectroscopic $T_{\rm eff}$. The SED model parameter distributions of stellar mass and evolutionary age reveal significant variation in the duration of star formation among four large-scale stellar overdensities within the CNC and a large distributed stellar population. Star formation began ${\sim}10$ Myr ago and continues to the present day, with the star formation rate peaking ${

description: High-dose of vitamin C (L-ascorbic acid, ascorbate) exhibits anti-tumoral effects, primarily mediated by pro-oxidant mechanisms. This cytotoxic effect is thought to affect the reciprocal crosstalk between redox balance and cell metabolism in different cancer types. Vitamin C also inhibits the growth of papillary thyroid carcinoma (PTC) cells, although the metabolic and redox effects remain to be fully understood. To shed light on these aspects, PTC-derived cell lines harboring the most common genetic alterations characterizing this tumor were used. Cell viability, apoptosis, and the metabolome were explored by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide test (MTT), flow cytometry, and UHPLC/MS. Changes were observed in redox homeostasis, with increased reactive oxygen species (ROS) level and perturbation in antioxidants and electron carriers, leading to cell death by both apoptosis and necrosis. The oxidative stress contributed to the metabolic alterations in both glycolysis and TCA cycle. Our results confirm the pro-oxidant effect of vitamin C as relevant in triggering the cytotoxicity in PTC cells and suggest that inhibition of glycolysis and alteration of TCA cycle via NAD+ depletion can play an important role in this mechanism of PTC cancer cell death.

description: Abstract: Processes involving heavy quarks are a crucial component of the LHC physics program, both by themselves and as backgrounds for Higgs physics and new physics searches. In this work, we critically reconsider the validity of the widely-adopted approximation in which heavy quarks are generated at the matrix-element level, with special emphasis on the impact of the collinear logarithms associated with final-state heavy quark and gluon splittings. Our study, based on a perturbative fragmentation-function approach, explicitly shows that neglecting the resummation of collinear logarithms may yield inaccurate predictions, in particular when observables exclusive in the heavy quark degrees of freedom are considered. Our findings motivate the use of schemes which encompass the resummation of final-state collinear logarithms.

description: The U.S. Endangered Species Act is often criticized as pitting people against species by conserving habitat at the cost of jobs. Critics of current conservation policies argue that the protection of species is stripping landowners of their property rights and putting people in industries tied to resource extraction out of jobs. While changes in employment are important measures of the public costs of endangered species protection, relatively little is known about the labor market impacts of listing a species under the Endangered Species Act. We examine changes in employment associated with the lesser prairie chicken, an imperiled bird that was listed as threatened in May 2014. Using monthly county-level employment data and variation in potential prairie chicken habitat, we apply a difference-in-differences strategy to measure the employment impacts of the listing decision. We find evidence that employment declined after the listing by about 1% in counties with habitat relative to non-habitat areas. We also find that the impact is proportional to habitat, so counties with the most prairie-chicken habitat experienced the largest impacts on employment.

description: In diesem Projekt wird die Risikobewertung des Betriebs komplexer technischer Systeme mit datenbasierten Methoden untersucht. Diese erfordert die Betrachtung der Degradationszustände verschiedener Subsysteme sowie deren Interaktionen. Beispielhaft wird die Überwachung des Missionsrisikos unbemannter Flugsysteme (Unmanned Aerial Vehicles, UAVs) betrachtet. Am Beispiel einer hybriden Quad-Plane Konfiguration, welche die Vorteile eines Multicopters mit denen eines Starrflüglers vereint, werden die Subsysteme hinsichtlich ihrer Kritikalität analysiert und die Aktoren (Antriebs- und Stellsysteme) sowie die Batterie als zu überwachende Subsysteme ausgewählt. Für diese werden anhand von Prüfstandsdaten, Simulationsmodellen und öffentlichen Datensätzen Diagnose- und Prognoseansätze zur Überwachung ihres Gesundheitszustandes entwickelt.
Zur Betrachtung des Gesamtsystems wird ein Flugsimulationsmodell eingesetzt. Dieses ermöglicht, den Einfluss von Funktionseinbußen mehrerer Aktoren auf die Flugstabilität zu analysieren. Zur Simulation der Degradation wird eine zeitlich abnehmende Effizienz der Antriebsmotoren, eine zunehmende Varianz der Stellmotorsteuerung sowie eine sich verringernde Batteriekapazität modelliert.
Mehrere UAV-Missionssequenzen werden simuliert, wobei die Missionsprofile zufällig generiert und durch eine Wegplanung unter Berücksichtigung von Luftraumbeschränkungen ergänzt werden. Dabei wird auch der Einfluss von Wind und verschiedenen Flugmodi berücksichtigt, darunter Start, Landung und Übergangsphasen zwischen Starrflügel- und Multicopter-Flug.
Zur Risikobewertung wird ein Verfahren entwickelt, das den aktuellen Systemzustand mithilfe von Hidden-Semi-Markov-Modellen (HSMM) abschätzt. Simulierte Flugdaten werden für das Training in Segmente bis hin zu fehlgeschlagenen Missionen unterteilt, und mithilfe von K-Means- oder Entscheidungsbaum-Algorithmen geclustert. Die trainierten HSMMs sowie Entscheidungsbäume ermöglichen dann eine Analyse der Wahrscheinlichkeit eines Missionsfehlschlags.

description: Ceramic dual-phase oxygen transport membranes with the composition of 60wt.% Ce0.9Pr0.1O2-δ-40wt.%Pr0.6Sr0.4Fe1-xAlxO3-δ (x = 0.05, 0.1, 0.2, 0.3, 0.4, 0.6, 0.8, 1.0) (60CPO-40PSF1-xAxO) based on 60Ce0.9Pr0.1O2-δ-40Pr0.6Sr0.4FeO3-δ doped Al was successfully synthesized through a modified Pechini method. Crystal structure, surface microtopography and oxygen permeability are investigated systematically. The cell parameters of perovskite phase first increased and then decreased with the increase of Al content, which is related to the radius of the Al3+ and the formation of impurity phase. As x ranges from 0.1 to 0.8, the oxygen permeability of the materials first increases and then decreases, and the maximum value of oxygen permeation rate for 60CPO-40PSF1-xAxO membranes with 0.4mm thickness at 1000 °C is 1.12 mL min-1 cm-2 when x = 0.4. XRD measurements revealed high temperature stability and CO2-tolerant property of the dual-phase composites. The partial replacement of Fe$^{3+}$/Fe$^{4+}$ by Al$^{3+}$ causes the material not only to exhibit good stability, but also to increase the oxygen permeability of the membranes.

description: The Brazilian Sertão is the most populous semiarid region in the world, and faces the highest rates of poverty and food insecurity in Brazil. Irregular rainfall and climate variability make these social constraints even more difficult to be solved in the short term, since basic economic activities in the region, as dairy farming and subsistence agriculture, tend to be mainly affected by recurrent and prolonged droughts. This study analyzes the impacts of climate conditions on the agricultural production and how adaptative strategies may alleviate such effects. First, it analyzes the dynamics of climate variables between 1974 and 2013 in the semi-arid region of the State of Bahia, the largest and most populous State of Sertão. Secondly, based on a panel with climatic and production data, it assesses the ex-poste impacts of these climate variables on the agricultural production of the municipalities in the region. Thirdly, it estimates the relation between several adaptive strategies and the agricultural family farmers’ production, based on microdata of the Brazilian Agricultural Census for small farmers in the region. The study evaluates four main agricultural productions: milk, cattle, goat, sheep and corn. The final and general aim of this study is to discuss the effectiveness of strategies for small farmers which would create climate resilience and attenuate the negative impacts of climate change on agricultural production of this vulnerable region.

description: Abstract: We discuss anomaly cancellation in U(2) gauge theories in four dimensions. For a U(2) gauge theory defined with a spin structure, the vanishing of the bordism group Ω5Spin (BU(2)) implies that there can be no global anomalies, in contrast to the related case of an SU(2) gauge theory. We show explicitly that the familiar SU(2) global anomaly is replaced by a local anomaly when SU(2) is embedded in U(2). There must be an even number of fermions with isospin 2r + 1/2, for r ∈ ℤ≥0, for this local anomaly to cancel. The case of a U(2) theory defined without a choice of spin structure but rather using a spin-U(2) structure, which is possible when all fermions (bosons) have half-integer (integer) isospin and odd (even) U(1) charge, is more subtle. We find that the recently-discovered ‘new SU(2) global anomaly’ is also equivalent, though only at the level of the partition function, to a perturbative anomaly in the U(2) theory, which is this time a combination of a mixed gauge anomaly with a gauge-gravity anomaly. This perturbative anomaly vanishes if there is an even number of fermions with isospin 4r + 3/2, for r ∈ ℤ≥0, recovering the condition for cancelling the new SU(2) anomaly. Alternatively, this perturbative anomaly can be cancelled by a Wess-Zumino term, leaving a low-energy theory with a global anomaly, which can itself be cancelled by coupling to topological degrees of freedom.

description: The spin polarization of topological surface states is of high interest for possible applications in spintronics. At present, the only technique capable to measure the surface state spin texture is spin and angle resolved photoemission spectroscopy (SARPES). However, values reported by SARPES differed strongly. An established technique to measure the spin polarization of ferromagnetic materials is the so-called Meservey-Tedrow technique, which is based on spin dependent tunneling from a superconducting electrode to a ferromagnet. Here, we theoretically investigate how the Meservey-Tedrow technique can be adapted to topological insulators. We demonstrate that with a specific device geometry it is possible to determine the in-plane component of the spin polarization of topological surface states. More complex device geometries can access the full momentum dependence of the spin polarization. We also show that it is possible to extract the spin-flip scattering rate of surface electrons with the same devices.

description: Active targeting with controlled delivery of anti-inflammatory drugs to the bone is not sufficiently explored. In this study, concise and novel synthesis of a hydroxy-bisphosphonic acid (HBPA) prodrug containing ibuprofen is described. The key step consisted of preparing the HBPA function from a carboxylic acid precursor, in mild conditions and using appropriate Arbuzov reactions with tris(trimethylsilyl)phosphite. This prodrug would be an excellent candidate for the treatment of bone inflammation diseases such as rheumatoid arthritis.

The system is solved providing a novel derivation of an essentially known expression. We stress a description of the underlying geometry in terms of the Distance Geometry of a tetrahedron discussed by Davydychev-Delbourgo [1], a tetrahedron which is the dual on-shell diagram. In addition, the singular locus is identified and the diagram's value on the locus's two components is expressed as a linear combination of descendant bubble diagrams. The massless triangle and the associated magic connection are revisited.

description: Chiral 2,5-diketopiperazine (2,5-DKP) derivatives have a broad range of biological activities in the medicinal field. The synthetic protocols of 1,3-disubstituted 2,5-DKPs via base-catalyzed cyclization of chloroacetamide have been reported. However, there are several drawbacks, such as an overly long reaction time, low to moderate yield, and racemization of the products. The sequence modified herein of 1,3-disubstituted 2,5-DKPs involves microwave-assisted cyclization. It increases yields and reduces reaction time. Furthermore, employing N-PMB protection prevents racemization, which frequently occurs in the base-catalyzed cyclization reaction. Consequently, the rapid synthetic method of enantiomerically pure 1,3-disubstituted 2,5-DKPs via microwave reaction was established successfully. The key step of the synthetic method

description: The 28 lock and dams sites on the upper Mississippi River is currently central to transporting U.S. agricultural commodities to the world market. This aging lock and dam system and slow double lockage process at the 600-foot locks have generated concern about its navigational efficiency. The objective of this study is to examine the determinants of delay occurred at the lock and dam system on the River. The focus is on the impact of lockage processing time (lock capacity issue) and unscheduled outages/stalls (system management issue) on lock delay. Results suggest that reduction in processing time reduces lock delay considerably. In addition, increases in the number of unscheduled outage cause by weather issue result in more delay hours. Delays at a given lock is also affected by lockage duration, the average duration of unscheduled stalls caused by weather, the unscheduled outage related to the occurrence of mechanical and vessel issues at nearby locks.

description: Abstract: Adolescent self-injury is a widespread public health problem, but long-term longitudinal studies from European countries are rare. Self-injury in males and sex differences are poorly understood. This study describes the prevalence, frequency, age-related course, and recurrence of, and mental health services use related to adolescent self-injury. Data came from a Swiss prospective-longitudinal cohort study (N = 1482). Adolescents (52% male) reported frequency of self-injury and mental health services use (including reasons for and types of services use, hospitalizations) at ages 13, 15, 17, and 20. Between ages 13–20, 27% of adolescents reported self-injury at least once. In males, prevalence decreased from 12 to 5%; in females self-injury peaked at age 15 (16%) and then decreased (11% at age 20). In males, recurrence of self-injury increased after age 15 (from odds ratio [OR] < 3 to OR > 10); in females, recurrence was high from age 13 onwards (OR > 5). Predictors of recurrence included childhood/early adolescent internalizing symptoms and early self-injury onset. Typically, less than half of adolescents with self-injury used mental health services. Males with self-injury used services mainly for externalizing problems, learning difficulties, and attention/concentration problems; females for depression or self-injury, family problems, and victimization. Types of services used changed with age, and adolescents with self-injury had increased rates of hospitalization. There are notable sex differences in the longitudinal course of self-injury and reasons for related mental health services use. Treating early internalizing symptoms could be a promising target for preventing recurrent self-injury. Males are at particular risk of not receiving adequate treatment for self-injury.

description: Discovery of M. helenor populations in Southern Andean Yungas
 For a long time there were no Morpho specimens available from the Southern Andean Yungas, but in 1984 Gilbert Lachaume obtained a male of M. godartii, from between Muyupampa and Aratial (Sucre-Camiri road), (figured in Blandin 2007b). Since 2001, 37 males and 11 females of M. helenor were collected in 13 localities distributed in the Southern Andean Yungas, from Cordillera Province (Santa Cruz dept.), in the north, to Aniceto Arce Province (Tarija dept.) near the Argentine border (Appendix 4). Altitudes vary from 500 m to 1400 m a.s.l., with ten localities above 800 m a.s.l (Fig.4). The Southern Andean Yungas form a mosaic of semi-deciduous forest ecosystems, ranging from sub-humid to dry. M. helenor populations have been found mainly in Sub-humid Tucuman forests in the upper Subandine belt, but also in Sub-humid forests similar to ecosystems existing in Beni lowlands, and in Chiquitania, in the center of Santa Cruz department (Fig.9).
 These populations differ from both M. h. coelestis and M. h. theodorus (Fig.10). Males are characterized by wider black margins, particularly on the hindwings (table 5). Females have rather narrow blue bands, with wide margins overlapping the white forewings pupillary points. Overall these specimens exhibit a unique pattern that justifies a new subspecies description.

description: Abstract: It is known that the Einstein gravitational field equations in D > 4 spacetime dimensions have no time-independent non-singular compactification solutions to de Sitter space if the D-dimensional stress tensor satisfies the Strong Energy Condition (SEC). Here we show, by example, that the SEC alone does not exclude time-dependent non-singular compactifications to de Sitter space, in Einstein conformal frame. However, this possibility is excluded by the combined SEC and Dominant Energy Condition (DEC) because the DEC forces a time-evolution towards a singular D-metric.
Impacts of U.S. Production-Dependent Ethanol Policy on Agricultural Markets

description: U.S. agricultural commodity prices have been volatile in recent years, attributed to many factors, including renewable fuel standard (RFS) mandates. While the RFS is legislatively able to be altered, the mandate largely required the same volume of corn for ethanol in the 2012 drought year as it would have if 2012 were a normal production year. This contributed to a surge in corn prices, having significant economic ramifications throughout the agricultural industry. An important question that arose from these events was if this variability was avoidable with a RFS relaxation policy? In this work, the economic effects of a policy that relaxes ethanol mandates in cases of major corn production shortfalls is investigated to determine the market relationships between RFS policy and commodity markets. This is done in a three step process. First the historical incidence of shortfalls is addressed by developing a stationary probability distribution of total and regional production using econometric procedures. Second, the short-run economic impact of RFS relaxation alternatives is investigated using an optimization modeling framework where crop mix and livestock breeding herds are held fixed. Third, the long-run implications of RFS relaxation are investigated by incorporating a stochastic optimization framework of ag-producer decisions with recourse. When a shortfall driven relaxation policy is in place, crop mix/livestock breeding decisions are able to adjust. The results show RFS relaxation has a significant impact on reducing price spikes and livestock production impacts due to reduced feeding costs when shortfalls occur. Although an ethanol waiver benefits consumers through decreased commodity prices, the reduction in producer welfare was found to be larger, resulting in an overall negative agricultural sector welfare impact. In the long-run, the RFS relaxation mitigates price spikes during production shortfall years but also stimulates a producer response of decreasing corn acreage due to lower expected prices. This caused corn prices in non-shortfall years to increase, resulting in a negligible impact on the average long-run corn prices, while reducing commodity price variability. The model findings demonstrated that risk reduction implications could exist from a production-dependent conventional ethanol waiver, with limited long-run changes to future expected prices.

description: Abstract: We have recently shown that a class of counterexamples to (weak) cosmic censorship in anti-de Sitter spacetime is removed if the weak gravity conjecture holds. Surprisingly, the minimum value of the charge to mass ratio necessary to preserve cosmic censorship is precisely the weak gravity bound. To further explore this mysterious connection, we investigate two generalizations: adding a dilaton or an additional Maxwell field. Analogous counterexamples to cosmic censorship are found in these theories if there is no charged matter. Even though the weak gravity bound is modified, we show that in each case it is sufficient to remove these counterexamples. In most cases it is also necessary.

description: Janus particles propel themselves by generating concentration gradients along their active surface. This induces a flow near the surface, known as the diffusio-osmotic slip, which propels the particle even in the absence of externally applied concentration gradients. In this work, we study the influence of viscoelasticity and shear-thinning (described by the second-order-fluid and Carreau model, respectively) on the diffusio-osmotic slip on an active surface. Using matched asymptotic expansions, we provide an analytical expression for the modification of slip induced by the non-Newtonian behavior. The results reveal that the modification in slip velocity arising from polymer elasticity is proportional to the second tangential derivative of the concentration field. Using the reciprocal theorem, we estimate the influence of this modification on the mobility of a Janus sphere. The current study also has direct implications on the understanding of the transport of complex fluids in diffusio-osmotic pumps.

description: This paper estimates the effect of extreme weather and climate events on the subjective wellbeing of US residents. We match forty two billion-dollar disaster events with individual survey data between 2005 and 2010. We find that being affected by a disaster has a negative and robust impact on life satisfaction that disappears 6 to 8 months after the event. In our sample severe storms are the main culprit in the reduction of life satisfaction; droughts also have a negative impact on life satisfaction and exhibit a more persistent effect.

description: Recently we have updated a multi-phase transport (AMPT) model with modern parton distribution functions of nuclei (nPDFs). Here we study open charm production in the updated AMPT model and compare to the experimental data from $pp$ and $AA$ collisions over a wide range of collision energies. Besides the update of nPDFs, we have removed the transverse momentum cutoff on initial heavy quark productions and also included the resultant heavy flavor cross section into the total minijet cross section in the initial condition as described by the HIJING model. We show that the AMPT model with these updates provides a much better description of the yields and transverse momentum spectra of various open charm hadrons in comparison with the experimental data. This lays the foundation for further heavy flavor studies within the transport model approach.
