description: In this paper, we investigate the structure and evolution of customer-supplier networks in Japan using a unique dataset that contains information on customer and supplier linkages for more than 500,000 incorporated non-financial firms for the five years from 2008 to 2012. We find, first, that the number of customer links is unequal across firms; the customer link distribution has a power-law tail with an exponent of unity (i.e., it follows Zipf’s law). We interpret this as implying that competition among firms to acquire new customers yields winners with a large number of customers, as well as losers with fewer customers. We also show that the shortest path length for any pair of firms is, on average, 4.3 links. Second, we find that link switching is relatively rare. Our estimates indicate that the survival rate per year for customer links is 92 percent and for supplier links 93 percent. Third and finally, we find that firm growth rates tend to be more highly correlated the closer two firms are to each other in a customer-supplier network (i.e., the smaller is the shortest path length for the two firms). This suggests that a non-negligible portion of fluctuations in firm growth stems from the propagation of microeconomic shocks – shocks affecting only a particular firm – through customer-supplier chains.

Several problems, mostly from real algebraic geometry / polynomial systems, have been shown complete (under many-one reduction by polynomial-time Turing machines) for this class. We exhibit a new one based on questions about expressions built from cross products only.

description: Geometrically frustrated spin systems often do not exhibit long-range ordering, resulting in either quantum-mechanically disordered states, such as quantum spin liquids, or classically disordered states, such as spin ices or spin glasses. Geometric frustration may play a similar role in charge ordering, potentially leading to unconventional electronic states without long-range order; however, there are no previous experimental demonstrations of this phenomenon. Here, we show that a charge-cluster glass evolves upon cooling in the absence of long-range charge ordering for an organic conductor with a triangular lattice, theta-(BEDT-TTF)2RbZn(SCN)4. A combination of time-resolved transport measurements and x-ray diffraction reveal that the charge-liquid phase has charge clusters that fluctuate extremely slowly (<10-100 Hz) and heterogeneously. Upon further cooling, the cluster dynamics freeze, and a charge-cluster glass is formed. Surprisingly, these observations correspond to recent ideas regarding the structural glass formation of supercooled liquids, indicating that a glass-forming charge liquid relates correlated-electron physics to glass physics in soft matter.

description: This paper presents an algorithm for Monte Carlo fixed-lag smoothing in state-space models defined by a diffusion process observed through noisy discrete-time measurements. Based on a particles approximation of the filtering and smoothing distributions, the method relies on a simulation technique of conditioned diffusions. The proposed sequential smoother can be applied to general non linear and multidimensional models, like the ones used in environmental applications. The smoothing of a turbulent flow in a high-dimensional context is given as a practical example.

description: Kann man Bewusstsein, Realität, Gewahrsein und freien Willen auf ein einziges Grundmuster zurückführen? Ohne etwas von ihnen aufzugeben? Kann das Universum sowohl real als auch individuell existieren, ohne sich aus beidem zusammenzusetzen? Dieser Dialog begründet Bewusstsein und Entscheidungsfreiheit auf der Basis eines neuen Realitätskonzepts, das auch das Unendliche einbezieht, soweit wir es verstehen. Bereits die einfachste Unterscheidung beinhaltet Bewusstsein. Sie ist nicht statisch, sondern ein ständiger Perspektivenwechsel. Aus ihrer Ganzheit und Bewegung aber entsteht Wahlfreiheit, die mehr ist als umgedeutete Notwendigkeit und Unvorhersagbarkeit. Obwohl Entscheidungen letztlich das ganze Universum einbeziehen, sind sie in unterschiedlichem Maß auch hier und jetzt frei. Die Einheit und Offenheit des Unendlichen ermöglicht dem Individuum eine Kreativität, die mittelbar und unmittelbar in alle anderen Individuen eingeht, ohne sie zu behindern. Ein gegenteiliger Eindruck entsteht nur in einem verengten Gewahrsein. Aber sogar das bewussteste und freieste Gewahrsein kann weder alle Entscheidungen vorwegnehmen noch eine Individualität auslöschen. Deren Kreativität ist gesichert.

description: The species-area relationship (SAR) has proven to be one of the few strong generalities in ecology. The temporal analog of the SAR, the species-time relationship (STR), has received considerably less attention. Recent work primarily from the temperate zone has aimed to merge the SAR and the STR into a synthetic and unified species-time-area relationship (STAR) as originally envisioned by Preston (1960). Here we test this framework using two tropical tree communities and extend it by deriving a phylogenetic-time-area relationship (PTAR). The work finds some support for Preston's prediction that diversity-time relationships, both species and phylogenetic, are sensitive to the spatial scale of the sampling. Contrary to the Preston's predictions we find a decoupling of diversity-area and diversity-time relationships in both forests as the time period used to quantify the diversity-area relationship changes. In particular, diversity-area and diversity-time relationships are positively correlated using the initial census to quantify the diversity-area relationship, but weakly or even negatively correlated when using the most recent census. Thus, diversity-area relationships could forecast the temporal accumulation of biodiversity of the forests, but they failed to “back-cast” the temporal accumulation of biodiversity suggesting a decoupling of space and time.

description: Artificial intelligence (AI) offers the potential to support healthcare delivery, but poorly trained or validated algorithms bear risks of harm. Ethical guidelines stated transparency about model development and validation as a requirement for trustworthy AI. Abundant guidance exists to provide transparency through reporting, but poorly reported medical AI tools are common. To close this transparency gap, we developed and piloted a framework to quantify the transparency of medical AI tools with three use cases. Our framework comprises a survey to report on the intended use, training and validation data and processes, ethical considerations, and deployment recommendations. The transparency of each response was scored with either 0, 0.5, or 1 to reflect if the requested information was not, partially, or fully provided. Additionally, we assessed on an analogous three-point scale if the provided responses fulfilled the transparency requirement for a set of trustworthiness criteria from ethical guidelines. The degree of transparency and trustworthiness was calculated on a scale from 0% to 100%. Our assessment of three medical AI use cases pin-pointed reporting gaps and resulted in transparency scores of 67% for two use cases and one with 59%. We report anecdotal evidence that business constraints and limited information from external datasets were major obstacles to providing transparency for the three use cases. The observed transparency gaps also lowered the degree of trustworthiness, indicating compliance gaps with ethical guidelines. All three pilot use cases faced challenges to provide transparency about medical AI tools, but more studies are needed to investigate those in the wider medical AI sector. Applying this framework for an external assessment of transparency may be infeasible if business constraints prevent the disclosure of information. New strategies may be necessary to enable audits of medical AI tools while preserving business secrets.

description: Causal graph dynamics are transformations over graphs that capture two important symmetries of physics, namely causality and homogeneity. They can be equivalently defined as continuous and translation invariant transformations or functions induced by a local rule applied simultaneously on every vertex of the graph. Intrinsic universality is the ability of an instance of a model to simulate every other instance of the model while preserving the structure of the computation at every step of the simulation. In this work we present the construction of a family of intrinsically universal instances of causal graphs dynamics, each instance being able to simulate a subset of instances.

Survival of water ice in Jupiter Trojans

description: Jupiter Trojans appear to be a key population of small bodies to study and test the models of the Solar System formation and evolution. Because understanding the evolution of Trojans can bring strong and unique constraints on the origins of our planetary system, a significant observational effort has been undertaken to unveil their physical characteristics. The data gathered so far are consistent with Trojans having volatile-rich interiors (possibly water ice) and volatile-poor surfaces (fine grained silicates). Since water ice is not thermodynamically stable against sublimation at the surface of an object located at ~5 AU, such layering seems consistent with past outgassing. In this work, we study the thermal history of Trojans after the formation of a dust mantle by possible past outgassing, so as to constrain the depth at which water ice could be stable. We find that it could have survived 100 m below the surface, even if Trojans orbited close to the Sun for ~10,000 years, as suggested by the most recent dynamical models. Water ice should be found ~10 m below the surface in most cases, and below 10 cm in the polar regions in some cases.
Prediction of phonon-mediated high temperature superconductivity in stoichiometric Li$_2$B$_3$C

description: The discovery of superconductivity in Magnesium Diborate (MgB$_2$) has stimulated great interest in the search of new superconductors with similar lattice structures. Unlike cuprate or iron-based superconductors, MgB$_2$ is indisputably a phonon-mediated high temperature superconductor. The emergence of high temperature superconductivity in this material results from the strong coupling between the boron $σ$-bonding electrons around the Fermi level and the bond-stretching optical phonon modes. Here we show, based on the first-principles calculations, that Li$_2$B$_3$C is such a good candidate of superconductor whose superconducting transition temperature (T$_c$) might be even higher than MgB$_2$. Li$_2$B$_3$C consists of alternating graphene-like boron-carbon layers and boron-boron layers with intercalated lithium atoms between them. Similar to MgB$_2$, Li$_2$B$_3$C is inherently metallic and possesses two $σ$- and two $π$-electron bands around the Fermi energy. The superconducting pairs are glued predominately by the strong interaction between boron $σ$-bonding electrons and various optical phonon modes.

Short Homotopically independent loops on surfaces

Year: 2013
Subjects: subject: Differential Geometry (math.DG)
subject: FOS: Mathematics

description: In this paper, we are interested in short homologically and homotopically independent loops based at the same point on Riemannian surfaces and metric graphs. First, we show that for every closed Riemannian surface of genus $g \geq 2$ and area normalized to $g$, there are at least $\ceil{\log(2g)+1}$ homotopically independent loops based at the same point of length at most $C\log(g)$, where $C$ is a universal constant. On the one hand, this result substantially improves Theorem $5.4.A$ of M. Gromov in \cite{G1}. On the other hand, it recaptures the result of S. Sabourau on the separating systole in \cite{SS} and refines his proof. Second, we show that for any two integers $b\geq 2$ with $1\leq n\leq b$, every connected metric graph $Γ$ of first Betti number $b$ and of length $b$ contains at least $n$ homologically independent loops based at the same point and of length at most $24(\log(b)+n)$. In particular, this result extends Bollobàs-Szemerédi-Thomason's $\log(b)$ bound on the homological systole to at least $\log(b)$ homologically independent loops based at the same point. Moreover, we give examples of graphs where this result is optimal.

description: Behavior Engineering (BE) provides a rigorous way to derive a formal specification of a software system from the requirements written in natural language. Its graphical specification language, Behavior Tree (BT), has been used with success in industry to systematically translate large, complex, and often erroneous requirements into an integrated model of the software system. BE's process, the Behavior Modeling Process (BMP), allows requirements to be translated into individual requirement BTs one at a time, which are then integrated to form a holistic view of the system. The integrated BT then goes through a series of modifications to construct a specification BT, which is used for validation and verification. The BMP also addresses different types of defects in the requirements throughout its process. However, BT itself is a graphical modeling notation, and the types of integration relations, how they correspond to particular issues, how they should be integrated and how to get formal specification have not been clearly defined. As a result, the BMP is informal, and provides guidelines to perform all these tasks on an ad-hoc basis. In this paper, we first introduce a mathematical framework which defines the graphical form of BTs which we use to define the integration relationships of BTs and to formalize the integration strategy of the BMP. We then formulate semi-automated requirements defects detection techniques by utilizing this underlying mathematical framework, which may be extended to formalize the BMP, develop change management framework for it, build techniques for round-trip engineering and so on.

description: The notion of source states characterizing the X-ray emission from black hole binaries has revealed to be a very useful tool to disentangle the complex spectral and aperiodic phenomenology displayed by those classes of accreting objects. We seek to use the same tools for Ultra-Luminous X-ray (ULX) sources. We analyzed the data from the longest observations obtained from the ULX source in NGC 5408 (NGC 5408 X-1) taken by XMM-Newton. We performed a study of the timing and spectral properties of the source. In accordance with previous studies on similar sources, the intrinsic energy spectra of the source are well described by a cold accretion disc emission plus a curved high-energy emission component. We studied the broad-band noise variability of the source and found an anti-correlation between the root mean square variability in the 0.0001-0.2Hz and intensity, similarly to what is observed in black-hole binaries during the hard states. We discuss the physical processes responsible for the X-ray features observed and suggest that NGC 5408 X-1 harbors a black hole accreting in an unusual bright hard-intermediate state.

description: Gran numero di persone, in particolare nelle stagioni primavera ed autunno, praticano, come passatempo o per passione, la ricerca e la raccolta di funghi. Le specie fungine, però, non sono tutte commestibili: infatti, alcune, a causa delle loron caratteristiche organolettiche o per la quantità di tossine presenti nella loro composizione, non possono essere consumate. In particolare, se si tratta di specie tossiche, queste possono causare problematiche di salute più o meno gravi che si possono protrarre per più o meno tempo. Per prevenire intossicazioni alimentari causate dal consumo di funghi sono stati istituiti, presso i SIAN delle ASL, gli Ispettorati Micologici. All’interno degli Ispettorati operano micologi,mche hanno ottenuto questa nomina a seguitom della partecipazione ad uno specifico corso con superamento di una prova finale. Le attività svolte all’interno di questi servizi sono molteplici, ma, in questo caso, la concentrazione è stata fatta ricadere sull’attività di consulenza messa a disposizione dei privati cittadini che vogliono consumare in sicurezza i funghi che hanno raccolto. L’obiettivo è stato determinare il gradimento, da parte della popolazione che ne ha fatto uso, del servizio proposto, andando a contattare 100 persone, che nell’anno 2021 hanno usufruito della consulenza presso gli Ispettorati Micologici delle ASL TO4 e TO5, le quali si sono prestate alla compilazione di un questionario anonimo. Il questionario era composto da circa dieci domande che comprendevano domande generali rispetto al servizio e qualche domanda per comprendere, in media, le conoscenze della popolazione sull’ambito micologico. I risultati ottenuti hanno risaltato quale sia stato ad ora il mezzo di comunicazione per raggiungere maggiormente la popolazione, in particolare la fascia interessata al mondo dei funghi, nonché come migliorare qualche aspetto del servizio, grazie a dei consigli, manifestato solo in minima parte delle persone, con informazioni di base sulla micologia (con un’autovalutazione dei partecipanti).

description: A 52-year-old patient from Bangladesh, known for hypertension for the last year, was taking oral antihypertensives. Nonetheless, he still had uncontrolled blood pressure, and no associated symptoms. The patient was referred to Emergency with a presenting complaint of high blood pressure, and high aldosterone and low renin levels. Therefore, a subsequent work-up plan was recommended for him. As per the lab reports, the patient was found to be suffering from primary aldosteronism. This was concluded by looking at his lab values, which were seen to be as follows: Aldosterone: 320 ng/L, Renin: 2.55 ng/L, Potassium: 5.2 mmol/L. An MRI of the adrenal gland was ordered for this patient, both with and without contrast. The findings of the MRI were consistent with left adrenal adenoma. An approximately 14 x 10.4 x 10.8 mm, oblong-shaped focal lesion, along the maximum TS, AP, and CC dimensions was appreciated.

description: A 52-year-old patient from Bangladesh, known for hypertension for the last year, was taking oral antihypertensives. Nonetheless, he still had uncontrolled blood pressure, and no associated symptoms. The patient was referred to Emergency with a presenting complaint of high blood pressure, and high aldosterone and low renin levels. Therefore, a subsequent work-up plan was recommended for him. As per the lab reports, the patient was found to be suffering from primary aldosteronism. This was concluded by looking at his lab values, which were seen to be as follows: Aldosterone: 320 ng/L, Renin: 2.55 ng/L, Potassium: 5.2 mmol/L. An MRI of the adrenal gland was ordered for this patient, both with and without contrast. The findings of the MRI were consistent with left adrenal adenoma. An approximately 14 x 10.4 x 10.8 mm, oblong-shaped focal lesion, along the maximum TS, AP, and CC dimensions was appreciated. This lesion was implicating the inferior portion of the left adrenal gland lateral limb, and exhibiting low to intermediate signal intensity on all provided sequences with signal dropout on out of the phase sequence. Moreover, minimal peripheral contrast enhancement was noted in the post-contrast administration images. This led to a prompt referral to the surgery department where the patient was evaluated and, within a week, operated on for the tumor successfully. This paper deals with the evaluation, diagnosis, and postoperative management of this patient who arrived at the hospital with no suspicion of the tumor that he had in his adrenal glands. Finally, it also summarizes the post-operative symptoms experienced by the patient and how they were managed on the spot to prevent any ensuing complications.

description: The quantum discord, which quantifies the amount of quantum correlations present between parts of a system, is investigated for antiferromagnetic spin systems. The discord for a pair of spins in the many-spin ground state is related to the diagonal and off-diagonal spin-spin correlation functions and the local magnetization. For isotropic and translationally invariant states, the discord is shown to be a function of the diagonal correlation function only. Thus, near a thermal/quantum critical point, the discord for a pair of spins shows long-range behavior, analogously of the correlation function. The discord exhibits a kink singularity as a function of the anisotropy parameter for the the ground state of the Heisenberg model, for both nearest-neighbor spins as well as for well-separated spins. The preferred measurement basis for the minimum conditional entropy, which determines the discord, changes discontinuously across the critical point. The conditional entropy distribution over all possible the measurement basis is investigated. For the isotropic model, the distribution is just a delta-function, whereas it has a twin-peak structure for anisotropic model. It is shown that the average value and the mean-square fluctuation of the conditional entropy also show a signature of the critical-point behavior.

description: In this paper, we explore relationships between two models of systems which are governed by only the local interactions of large collections of simple components: cellular automata (CA) and the abstract Tile Assembly Model (aTAM). While sharing several similarities, the models have fundamental differences, most notably the dynamic nature of CA (in which every cell location is allowed to change state an infinite number of times) versus the static nature of the aTAM (in which tiles are static components that can never change or be removed once they attach to a growing assembly). We work with 2-dimensional systems in both models, and for our results we first define what it means for CA systems to simulate aTAM systems, and then for aTAM systems to simulate CA systems. We use notions of simulate which are similar to those used in the study of intrinsic universality since they are in some sense strict, but also intuitively natural notions of simulation. We then demonstrate a particular nondeterministic CA which can be configured so that it can simulate any arbitrary aTAM system, and finally an aTAM tile set which can be configured so that it can be used to simulate any arbitrary nondeterministic CA system which begins with a finite initial configuration.

description: This study examined the effect of health-related knowledge on adolescents· interest and participation in physical activity. Specifically. the researcher employed a quasi-experimental design with repeated measures to examine the implementation of a health-related curriculum unit (Physical Best) on adolescent knowledge. interest, and physical activity participation, in comparison with students in comparison group who learned the traditional school district curriculum. The researcher used pre and posttests to collect adolescents· health-related fitness knowledge. personal interest. and physical activity participation. The sample size was 90 participants. with 41 adolescents in the experimental group, and 49 in the comparison group. The researcher hypothesized that. compared with the comparison group; adolescents in the experimental group would report higher posttests scores in health-related fitness knowledge. higher interest. and more physical activity participation. The researcher analyzed the data using descriptive statistical techniques and analysis of covariance to test the hypotheses. Overall. students in the experimental group reported statistically significantly higher attainment value, health-related knowledge, and number of steps after the experiment. than the comparison group. Along with the significant increase in health-related fitness knowledge. however. there was no significant increase in student interest in physical education, or after-school moderate-to-vigorous physical activity (MVPA) in the experimental group. These findings provided an encouraging picture of using health-related fitness curriculum unit to improve students' health-related fitness knowledge and attainment value for physical education. but somewhat inconsistent with other reports. More studies arc needed to identify the differences among the studies. and hopefully future studies \\ill be using longitudinal designs to further our understanding on this issue.

description: The motility of microorganisms is often biased by gradients in physical and chemical properties of their environment, with myriad implications on their ecology. Here we show that fluid acceleration reorients gyrotactic plankton, triggering small-scale clustering. We experimentally demonstrate this phenomenon by studying the distribution of the phytoplankton Chlamydomonas augustae within a rotating tank and find it to be in good agreement with a new, generalized model of gyrotaxis. When this model is implemented in a direct numerical simulation of turbulent flow, we find that fluid acceleration generates multi-fractal plankton clustering, with faster and more stable cells producing stronger clustering. By producing accumulations in high-vorticity regions, this process is fundamen- tally different from clustering by gravitational acceleration, expanding the range of mechanisms by which turbulent flows can impact the spatial distribution of active suspensions.

description: A 38-years old male patient, documented case of Irritable Bowel Syndrome (IBS), presented to the clinic with complaints of severe central abdominal pain and severe rash. The day before presenting to the clinic, the patient went to the Emergency Department for the same complaints. According to the patient, the abdominal pain was colicky in nature. There were no associated complaints of nausea, vomiting, or GI bleeding, but did have an upper respiratory tract infection three weeks ago, after which he had started experiencing these symptoms. His infection was treated with oral antibiotics and was soon got resolved. The staff at the ED had investigated the cause, including a CT abdomen with contrast, but the reports had been all clear. He had mildly raised serum creatinine at that time. On clinical examination, the patient had severe tenderness in his abdominal region. The rash was extensive, reddish, raised, and purpuric in nature and had spread all over his lower limbs and hips on both sides. The upper limbs were also involved up to the forearms. All the lab investigations conducted on the patient were normal, including CBC, Creatinine, Serum C3, C4, and the rheumatoid factor. CRP was found to be elevated and positive occult blood was seen in the stool of the patient. The combination of the above medical symptoms and investigations revealed that the patient was suffering from abdominal angina. The symptoms had a classic presentation pattern: positive occult blood in stool, a purpuric rash, abdominal pain, and renal involvement that was preceded by a documented case of upper respiratory tract infection (URTI). Later, the patient was found to have all findings consistent with immune-mediated IgA vasculitis (Henoch Schonlein Purpura) and was then treated accordingly. The above-mentioned case was an interesting presentation: the condition is not often presented to the hospital with such clear manifestations, leading to an absolute diagnosis. The following sections of this case study will explore how the patient was diagnosed, treated, and managed accordingly to save his life.

description: We study the scattering phase shift of Dirac fermions at graphene edge. We find that when a plane wave of a Dirac fermion is reflected at an edge of graphene, its reflection phase is shifted by the geometric phase resulting from the change of the pseudospin of the Dirac fermion in the reflection. The geometric phase is the Pancharatnam-Berry phase that equals the half of the solid angle on Bloch sphere determined by the propagation direction of the incident wave and also by the orientation angle of the graphene edge. The geometric phase is finite at zigzag edge in general, while it always vanishes at armchair edge because of intervalley mixing. To demonstrate its physical effects, we first connect the geometric phase with the energy band structure of graphene nanoribbon with zigzag edge. The magnitude of the band gap of the nanoribbon, that opens in the presence of the staggered sublattice potential induced by edge magnetization, is related to the geometric phase. Second, we numerically study the effect of the geometric phase on the Veselago lens formed in a graphene nanoribbon. The interference pattern of the lens is distinguished between armchair and zigzag nanoribbons, which is useful for detecting the geometric phase.

description: A universal deterministic inhibitor Petri net with 14 places, 29 transitions and 138 arcs was constructed via simulation of Neary and Woods' weakly universal Turing machine with 2 states and 4 symbols; the total time complexity is exponential in the running time of their weak machine. To simulate the blank words of the weakly universal Turing machine, a couple of dedicated transitions insert their codes when reaching edges of the working zone. To complete a chain of a given Petri net encoding to be executed by the universal Petri net, a translation of a bi-tag system into a Turing machine was constructed. The constructed Petri net is universal in the standard sense; a weaker form of universality for Petri nets was not introduced in this work.
