description: We consider the Cole-Hopf solution of the (1+1)-dimensional KPZ equation $\mathcal{H}^f(t,x)$ started with initial data $f$. In this article, we study the sample path properties of the KPZ temporal process $\mathcal{H}_t^f := \mathcal{H}^f(t,0)$. We show that for a very large class of initial data which includes any deterministic continuous initial data that grows slower than parabola ($f(x) \ll 1 + x^2$) as well as narrow wedge and stationary initial data, temporal increments of $\mathcal{H}_t^f$ are well approximated by increments of a fractional Brownian motion of Hurst parameter $\frac14$. As a consequence, we obtain several sample path properties of KPZ temporal properties including variation of the temporal process, law of iterated logarithms, modulus of continuity and Hausdorff dimensions of the set of points with exceptionally large increments.

description: The quantum-walk-based spatial search problem aims to find a marked vertex using a quantum walk on a graph with marked vertices. We describe a framework for determining the computational complexity of spatial search by continuous-time quantum walk on arbitrary graphs by providing a recipe for finding the optimal running time and the success probability of the algorithm. The quantum walk is driven by a Hamiltonian derived from the adjacency matrix of the graph modified by the presence of the marked vertices. The success of our framework depends on the knowledge of the eigenvalues and eigenvectors of the adjacency matrix. The spectrum of the Hamiltonian is subsequently obtained from the roots of the determinant of a real symmetric matrix $M$, the dimensions of which depend on the number of marked vertices. The eigenvectors are determined from a basis of the kernel of $M$. We show each step of the framework by solving the spatial searching problem on the Johnson graphs with a fixed diameter and with two marked vertices. Our calculations show that the optimal running time is $O(\sqrt{N})$ with an asymptotic probability of $1+o(1)$, where $N$ is the number of vertices.

description: In the present paper we study the stability problem for a stretched tube conveying fluid with boundary control. The abstract spectral problem concerns operator pencils of the forms \begin{equation*} \mathcal{M}\left(λ\right)=λ^2G+λD+C\quad\text{and}\quad\mathcal{P}\left(λ\right)=λI-T \end{equation*} taking values in different Hilbert product spaces. Thorough analysis is made of the location and asymptotics of eigenvalues in the complex plane and Riesz basisness of the corresponding eigenfunctions and eigenvectors. Well-posedness of the closed-loop system represented by the initial-value problem for the abstract equation \begin{equation*} \dot{x}\left(t\right)=Tx\left(t\right) \end{equation*} is established in the framework of semigroups as well as expansions of the solutions in terms of eigenvectors and stability of the closed-loop system operator $T$. For the parameters of the problem we give regions, larger than those in the literature, in which a stretched tube with flow, simply supported at one end, with a boundary controller applied at the other end, can be made exponentially stable.

description: The majority of studies that analyze the impact of entrepreneurship education on entrepreneurial attitudes, intentions, and venture activities report positive influences. However, several scholars have recently cast doubts about research methods and the generalizability of entrepreneurship education impact studies. In this study, we conducted a systematic literature review of the methods used in entrepreneurship education impact studies. Our results uncover significant methodological deficiencies and question the overwhelmingly positive impact of entrepreneurship education. Based on this evidence, we propose a series of recommendations to improve the reliability and validity of entrepreneurship education impact studies and we outline promising topics which are currently under-researched.

description: We consider the point-to-point continuum directed random polymer ($\mathsf{CDRP}$) model that arises as a scaling limit from $1+1$ dimensional directed polymers in the intermediate disorder regime. We show that the annealed law of a point-to-point $\mathsf{CDRP}$ of length $t$ converges to the Brownian bridge under diffusive scaling when $t \downarrow 0$. In case that $t$ is large, we show that the transversal fluctuations of point-to-point $\mathsf{CDRP}$ are governed by the $2/3$ exponent. More precisely, as $t$ tends to infinity, we prove tightness of the annealed path measures of point-to-point $\mathsf{CDRP}$ of length $t$ upon scaling the length by $t$ and fluctuations of paths by $t^{2/3}$. The $2/3$ exponent is tight such that the one-point distribution of the rescaled paths converges to the geodesics of the directed landscape. This point-wise convergence can be enhanced to process-level modulo a conjecture. Our short and long-time tightness results also extend to point-to-line $\mathsf{CDRP}$. In the course of proving our main results, we establish quantitative versions of quenched modulus of continuity estimates for long-time $\mathsf{CDRP}$ which are of independent interest.

Distribution and ecology (Figs. 4a, e–f). The species is known only from China: Nei Mongol Autonomous Region, Qinghai and Shaanxi provinces (Yang & Li 2018). It was redescribed by Li et al. (2013) from Nei Mongol under the name Nemoura cf. securigera Klapálek, 1907. We recently found this species at several localities in the Qinling Mountain, Shaanxi, the type locality of the species (unpublished data). We believe that the populations in Nei Mongol and Qinghai represent the same species as the Qinling populations. The species was never found in Qinling during summer surveys of recent years, but occurs during summer in Nei Mongol and Qinghai. It emerges from early April Nei Mongol and Qinling (unpublished data). Two of the Qinghai males were collected together with N. jixiangwangi at Deqian village (Fig. 4a), and another one was found in a forest stream at Qihankai valley (Fig. 4e).

description: We introduce the notion of an extremal subset in a geodesically complete space with curvature bounded above, i.e., a GCBA space. This is an analogue of an extremal subset in an Alexandrov space with curvature bounded below introduced by Perelman and Petrunin. We prove that under an additional assumption the set of topological singularities in a GCBA space forms an extremal subset. We also exhibit some structural properties of extremal subsets in GCBA spaces.

How the founders' general and specific human capital drives export activities of start-ups

Publisher: name: Elsevier B.V.
Year: 2016
Subjects: Export Start-up
Founder characteristics
Human capital

description: At first glance, a typical start-up does not seem to have the required capabilities to enter foreign markets. Nevertheless, 26% of the firms of a representative sample of Swiss start-ups already perform export activities three years after their foundation, and the firms with export activities generate 39% of their sales abroad on average. Previous studies identified the founders’ human capital as an important driver of early internationalization. In this paper, however, we find that differences exist in the effect of the founders’ general and specific human capital. While the founders’ general human capital affects both export propensity and intensity, their export-specific experience only affects export propensity but not intensity. Furthermore, we find evidence that the effect of general human capital is more persistent than the effect of specific human capital.

description: Multivariate extreme value distributions are a common choice for modelling multivariate extremes. In high dimensions, however, the construction of flexible and parsimonious models is challenging. We propose to combine bivariate max-stable distributions into a Markov random field with respect to a tree. Although in general not max-stable itself, this Markov tree is attracted by a multivariate max-stable distribution. The latter serves as a tree-based approximation to an unknown max-stable distribution with the given bivariate distributions as margins. Given data, we learn an appropriate tree structure by Prim's algorithm with estimated pairwise upper tail dependence coefficients as edge weights. The distributions of pairs of connected variables can be fitted in various ways. The resulting tree-structured max-stable distribution allows for inference on rare event probabilities, as illustrated on river discharge data from the upper Danube basin.

description: In this paper, the authors first consider the bidirectional estimates of several typical integrals. As some applications of these integral estimates, the authors investigate the pointwise multipliers from the normal weight general function space $F(p,μ,s)$ to the normal weight Bloch type space $\mathcal{B_ν}(B_{n})$ on the unit ball $B_{n}$ of $\mathbb{C}^{n}$, where $μ$ and $ν$ are two normal functions on $[0,1)$. For the special normal function $\displaystyle{μ(r)=(1-r^{2})^α\log^β\frac{e}{1-r^{2}}}$ ($α>0$, $-\infty<β<\infty$), the authors give the necessary and sufficient conditions of pointwise multipliers from $F(p,μ,s)$ to $\mathcal{B_ν}(B_{n})$ for all cases.

description: Using a three-wave prospective cross-lagged panel design, the study examined six-month stability of burnout, self-compassion and social support among sports coaches in terms of measurement invariance, mean-level change, rank-order stability, and structural stability. The participating coaches (N = 422; Mage = 44.48, SD = 11.03) completed an online questionnaire measuring self-compassion, social support, coach burnout and demographics at baseline and two follow-ups at three months and six months. The various forms of stability were assessed using structural equation modeling. There was no significant mean-level change in burnout, self-compassion, or social support, and all three constructs exhibited measurement invariance. Rank-order stability remained relatively high, ranging from 0.78 to 0.94 across the three time points. For all three constructs, covariances between latent factors were invariant over time, indicating high structural stability. While self-compassion and social support were positively related, both were negatively related to coach burnout. These results confirm the importance of preventing and addressing symptoms of burnout, low self-compassion and poor social support in sports settings.

description: Mobile parcel lockers have been recently proposed by logistics operators as a technology that could help reduce traffic congestion and operational costs in urban freight distribution. Given their ability to relocate throughout their area of deployment, they hold the potential to improve customer accessibility and convenience. In this study, we formulate the Mobile Parcel Locker Problem (MPLP) , a special case of the Location-Routing Problem (LRP) which determines the optimal stopover location for MPLs throughout the day and plans corresponding delivery routes. A Hybrid Q Learning Network based Method (HQM) is developed to resolve the computational complexity of the resulting large problem instances while escaping local optima. In addition, the HQM is integrated with global and local search mechanisms to resolve the dilemma of exploration and exploitation faced by classic reinforcement learning methods. We examine the performance of HQM under different problem sizes (up to 200 nodes) and benchmarked it against the exact approach and Genetic Algorithm (GA). Our results indicate that HQM achieves better optimisation performance with shorter computation time than the exact approach solved by the Gurobi solver in large problem instances. Additionally, the average reward obtained by HQM is 1.96 times greater than GA, which demonstrates that HQM has a better optimisation ability. Further, we identify critical factors that contribute to fleet size requirements, travel distances, and service delays. Our findings outline that the efficiency of MPLs is mainly contingent on the length of time windows and the deployment of MPL stopovers. Finally, we highlight managerial implications based on parametric analysis to provide guidance for logistics operators in the context of efficient last-mile distribution operations.

Type species: Neanura brasiliensis Arlé, 1959, by present designation
Diagnosis. No hypodermal blue pigment, white in ethanol. Ant III organ complete (5 S-chaetae). Ant IV with S 1– 8 subequal. Eyes 2+2, without dark pigment. Labral chaetotaxy: 0/2,4; labral ventro-distal sclerotisations rounded apically. Maxilla styliform. Mandible slender, with 2–3 teeth. No reticulations. Dorsal tubercles present, small, the internal ones not developed, those of Abd IV–VI larger. Head: tubercle Fr fused to An across midline, forming an Af tubercle, not fused to Oc or CL; no tubercles Di; tubercle De present; DL and (L+So) tubercles separated in lateral area. No tubercles Di on Th I–Abd IV, other tubercles all present; on abd V tubercles Di adjacent across midline, not fused; tubercles De and DL fused together laterally; on Abd VI, tubercles separated middorsally. No plurichaetosis. Standard arrangement and number of S-chaetae on half tergites of Th II–Abd V: 2 + ms, 2/11111. Dorsal ordinary macrochaetae ciliated, subparallel, with a small rounded apex. Claw untoothed, M-chaeta absent on tibiotarsi.
Etymology. After "Ita", that means stone in the indigenous language Tupi; a reference to the rocky mountains of Southeast Brazil, where the species of the genus was found.
Remarks. This new genus is the only Paleonurini genus endemic of the Neotropical region, as Paramanura Cassagnau, 1986, previously described from Venezuela highlands, has been subsequently assigned by its author to Pronura (Cassagnau, 1996). The body tubercles of Itanura gen. nov. are intermediately developed compared to those of Australonura Cassagnau, 1980 and Phradmon Greenslade & Deharveng, 1991, which have stronger tubercles, and those of Paleonura Cassagnau, 1982 and Pronura Delamare Deboutteville, 1953, where tubercles are not or weakly differentiated.
The combination of characters that distinguish Itanura gen. nov. from other Paleonurini genera is the presence of a tubercle Af on head, the adjacence of Di tubercle on Abd V and the absence of tubercles Di from head to Abd IV. The main differences of tubercle arrangement on head and Abd IV–VI between Southern Hemisphere tuberculate genera of Paleonurini are summarized in Figs 11–16. Evolutionary relationships between these genera are difficult to hypothetize from morphology alone, given the reticulate evolution of tubercule arrangement, and convergence may not be ruled out. Molecular approaches may be here the only way to solve the problem.

description: The potential of local impedance spectroscopy (IS) to access changes in emulsions and foams has been investigated. As test systems we used the separation of a simple oil/vinegar mixture as well as the whipping process of dairy cream. For the latter, IS data were compared to particle size distribution (PSD) measurements. Our measurements show that local IS is indeed a valuable tool to locally study processes in emulsion. On one hand, it seems to be very sensitive to small water quantities in oil thus being a suitable method for process control in water removing processes. On the other hand, concerning fat foams, it seems to be able to detect the evolution of foam structures. Both examples show that local IS could be a helpful tool for process control.

description: In this paper, we bring together career construction and dual embeddedness theories to examine how refugees reconstruct their careers after their arrivals in host countries. Based on in-depth data from 11 recently arrived refugees in Germany, we use comparative case study as a method to examine and theorize the relationship between dual embeddedness and refugee career reconstruction path. The results bring forth the notion of job creation as well as two mechanisms - information search and willingness to cope with uncertainty - through which refugees reconstruct their career, each of which has different implications for the degree of refugee career reconstruction. By combining behavioral with social network theories, we discuss the nature of job creation and job seeking, and offer new insights into both the career construction and dual embeddedness literatures as well as practical recommendations for refugee integration.

description: The energy spectrum of topological semimetals contains protected degeneracies in reciprocal space that correspond to Weyl, Dirac, or multifold fermionic states. To exploit the unconventional properties of these states, one has to access the electronic structure of the three-dimensional bulk. In this work, we present the first joint theory-experiment study of the electronic structure of a candidate topological semimetal with resonant inelastic X-ray scattering (RIXS). We resolve the bulk electronic states of FeSi using momentum-dependent RIXS at the Fe $L_3$ edge. We observe a broad excitation continuum devoid of sharp features, consistent with particle-hole scattering in an underlying electronic band structure. Using density functional theory (DFT), we calculate the electronic structure of FeSi and derive a band theory formulation of RIXS in the fast collision approximation to model the scattering process with zero adjustable parameters. While band theory predicts an excitation continuum with broad spectral features similar to the observed ones, discrepancies between theory and experiment suggest the presence of low-energy processes that DFT alone does not account for. This first study of RIXS in a topological semimetal shows that RIXS is a useful tool for revealing unanticipated behavior of bulk electronic states in this class of materials.

description: We study left invariant locally conformally product structures on simply connected Lie groups and give their complete description in the solvable unimodular case. Based on previous classification results, we then obtain the complete list of solvable unimodular Lie algebras up to dimension 5 which carry LCP structures, and study the existence of lattices in the corresponding simply connected Lie groups.

description: The existence of genuine complex conjugated poles in the gluon propagator is discussed and related to confinement, string tension and condensates. The existence of the anomalous poles leads to an untrivial analytic continuation from Euclidean to Minkowski space, where the pole part of the propagator is related to the spectrum of excited quasigluons.

description: Dyads composed of unacquainted females (n= 82) watched a cartoon while consuming salty aperitifsnacks. The Affective Communication Test was used to measure nonverbal expressiveness. Computingintraclass correlation coefficients, the extent to which participants within dyads matched each other’sfood intake was analyzed. Food intake matched highly for dyads with two expressive individuals andmoderately for dyads with one expressive participant. For dyads with two unexpressive participants,there was no evidence for matching behavior. Highly expressive people seem to be able to synchronizewith others and thereby allow for close matching. This is the first study to show an influence of person-ality on matching consumption behavior.

description: We aim to optimize the binary detection of Chronic Obstructive Pulmonary Disease (COPD) based on emphysema presence in the lung with convolutional neural networks (CNN) by exploring manually adjusted versus automated window-setting optimization (WSO) on computed tomography (CT) images. 7,194 CT images (3,597 with COPD; 3,597 healthy controls) from 78 subjects were selected retrospectively (10.2018-12.2021) and preprocessed. For each image, intensity values were manually clipped to the emphysema window setting and a baseline 'full-range' window setting. Class-balanced train, validation, and test sets contained 3,392, 1,114, and 2,688 images. The network backbone was optimized by comparing various CNN architectures. Furthermore, automated WSO was implemented by adding a customized layer to the model. The image-level area under the Receiver Operating Characteristics curve (AUC) [lower, upper limit 95% confidence] was utilized to compare model variations. Repeated inference (n=7) on the test set showed that the DenseNet was the most efficient backbone and achieved a mean AUC of 0.80 [0.76, 0.85] without WSO. Comparably, with input images manually adjusted to the emphysema window, the DenseNet model predicted COPD with a mean AUC of 0.86 [0.82, 0.89]. By adding a customized WSO layer to the DenseNet, an optimal window in the proximity of the emphysema window setting was learned automatically, and a mean AUC of 0.82 [0.78, 0.86] was achieved. Detection of COPD with DenseNet models was improved by WSO of CT data to the emphysema window setting range.

description: Palliative Care ist geleitet von Idealen, die Patient*innen als Individuen mit ihren einzigartigen Merkmalen, Vorlieben und Eigenschaften in den Mittelpunkt stellen. Aus diesem Grund scheint die Palliative Care auf den ersten Blick gut geeignet, Geschlecht als prägenden Faktor von Identitäten, Beziehungen und Erfahrungen anzuerkennen und in der Praxis zu berücksichtigen. Doch selbst in diesem Bereich, der reflektierter agiert als andere medizinische Fachgebiete, scheint das Thema Geschlechterdifferenzen und Geschlechterrollen mit ihren Auswirkungen auf die Praxis der Palliative Care bisher wenig beleuchtet.

Locality. Parque Nacional da Serra dos Órgãos (ICMBio), Teresópolis municipality, Rio de Janeiro State, Brazil. 2100 m a.s.l. Local coordinates: 22º27'38"S, 43º1'45"W. Leaf litter and soil of "campos de altitude".
Remarks. Labium with 2 x-papillae visible (Fig. 30). Head with Af composed of 7–8 tubercles separated from Oc and CL. Leg chaetotaxy of legs I–III as follows: Scx2– 0, 2, 2; Cx– 3, 7, 8; Tr– 6, 6, 6; Fe– 13, 12, 11; Tita– 18, 18, 17. Furcal rest with 4 chaetae, devoid of mi; Ve chaetae, on ventral anal valves, 13 (Fig. 32). For other differences see Table 6.
Discussion. The specimens of the three localities where Itanura brasiliensis comb. nov. was found are extremely similar, yet differences on important details of chaetotaxy and tubercle development are noteworthy (Table 6). In this way, they recall the pattern of closely related subspecies within Deutonura deficiens (Deharveng, 1984), suggesting that sampling intermediate locations in this Brazilian region may disclose a complex of parapatric forms (with narrow hybrid or overlapping zones), leading to upgrade these three populations to either subspecies or species level.

description: Project 8 has developed a novel technique, Cyclotron Radiation Emission Spectroscopy (CRES), for direct neutrino mass measurements. A CRES-based experiment on the beta spectrum of tritium has been carried out in a small-volume apparatus. We provide a detailed account of the experiment, focusing on systematic effects and analysis techniques. In a Bayesian (frequentist) analysis, we measure the tritium endpoint as $18553^{+18}_{-19}$ ($18548^{+19}_{-19}$) eV and set upper limits of 155 (152) eV (90% C.L.) on the neutrino mass. No background events are observed beyond the endpoint in 82 days of running. We also demonstrate an energy resolution of $1.66\pm0.19$ eV in a resolution-optimized magnetic trap configuration by measuring $^{83\rm m}$Kr 17.8-keV internal-conversion electrons. These measurements establish CRES as a low-background, high-resolution technique with the potential to advance neutrino mass sensitivity.

description: Die Forschungsarbeit beleuchtet die Technologie Robotic Process Automation (RPA) im Umfeld der Finanzfunktionen und umfasst sowohl die Aufarbeitung des aktuellen Forschungsstands als auch eine primäre Datenerhebung, die sich in zwei Teile gliedert: Einerseits wurden Best Practices in Unternehmen erhoben, welche bereits Erfahrung mit RPA haben. Andererseits erfolgte in Kooperation mit der BKW AG die Erarbeitung einer Fallstudie. Im Vordergrund standen das Nutzenpotenzial und die Anwendungsfälle in Finanzfunktionen sowie generelle Lessons Learned. Die Ergebnisse zeigen auf, dass das in der Theorie attestierte Nutzenpotenzial in der Praxis auftritt, wobei dessen Ausmaß von der Selektion geeigneter Prozesse abhängig ist. Hier haben sich finanzielle Transaktionsprozesse, charakterisiert durch wiederkehrend, gleichartig sowie eine kurze Einarbeitungszeit, als geeignet herauskristallisiert. Für die Implementierung von RPA ist ein Start mit einem motivierten Team sinnvoll, das erste Prozesse in einem Piloten automatisiert. Für die Verankerung im Unternehmen ist ein aktives Changemanagement sowie die frühzeitige Ausgestaltung des Operating Models empfohlen. Die Praxis zeigte zudem, dass einige Stolpersteine gezielt zu adressieren sind. Der Einsatz von RPA ist auch kein Selbstzweck, sondern bedarf einer sachlichen Grenznutzenabwägung.

description: It has been suggested that visual images are memorized across brief periods of time by vividly imagining them as if they were still there. In line with this, the contents of both working memory and visual imagery are known to be encoded already in early visual cortex. If these signals in early visual areas were indeed to reflect a combined imagery and memory code, one would predict them to be weaker for individuals with reduced visual imagery vividness. Here, we systematically investigated this question in two groups of participants. Strong and weak imagers were asked to remember images across brief delay periods. We were able to reliably reconstruct the memorized stimuli from early visual cortex during the delay. Importantly, in contrast to the prediction, the quality of reconstruction was equally accurate for both strong and weak imagers. The decodable information also closely reflected behavioral precision in both groups, suggesting it could contribute to behavioral performance, even in the extreme case of completely aphantasic individuals. Our data thus suggest that working memory signals in early visual cortex can be present even in the (near) absence of phenomenal imagery.

We also characterize adapted metrics as critical points of a natural functional defined on the conformal class.
