description: As shown in computer vision, the power of deep learning lies in automatically learning relevant and powerful features for any perdition task, which is made possible through end-to-end architectures. However, deep learning approaches applied for classifying medical images do not adhere to this architecture as they rely on several pre- and post-processing steps. This shortcoming can be explained by the relatively small number of available labeled subjects, the high dimensionality of neuroimaging data, and difficulties in interpreting the results of deep learning methods. In this paper, we propose a simple 3D Convolutional Neural Networks and exploit its model parameters to tailor the end-to-end architecture for the diagnosis of Alzheimer's disease (AD). Our model can diagnose AD with an accuracy of 94.1\% on the popular ADNI dataset using only MRI data, which outperforms the previous state-of-the-art. Based on the learned model, we identify the disease biomarkers, the results of which were in accordance with the literature. We further transfer the learned model to diagnose mild cognitive impairment (MCI), the prodromal stage of AD, which yield better results compared to other methods.

description: We consider two models for a pair of interacting particles in a random potential: (i) two particles with a Hubbard interaction in arbitrary dimensions and (ii) a strongly bound pair in one dimension. Establishing suitable correpondences we demonstrate that both cases can be described in terms familiar from theories of noninteracting particles. In particular, these two cases are shown to be controlled by a single scaling variable, namely the pair conductance $g_2$. For an attractive or repulsive Hubbard interaction and starting from a certain effective Hamiltonian we derive a supersymmetric nonlinear $σ$ model. Its action turns out to be closely related to the one found by Efetov for noninteracting electrons in disordered metals. This enables us to describe the diffusive motion of the particle pair on scales exceeding the one-particle localization length $L_1$ and to discuss the corresponding level statistics. For tightly bound pairs in one dimension, on the other hand, we follow early work by Dorokhov and exploit the analogy with the transfer matrix approach to quasi 1d conductors. Extending our study to M particles we obtain a M-particle localization length scaling like the Mth power of the one-particle localization length.

description: Let $t$ be a positive real number. A graph is called $t$-tough if the removal of any vertex set $S$ that disconnects the graph leaves at most $|S|/t$ components, and all graphs are considered 0-tough. The toughness of a graph is the largest $t$ for which the graph is $t$-tough, whereby the toughness of complete graphs is defined as infinity. A graph is minimally $t$-tough if the toughness of the graph is $t$, and the deletion of any edge from the graph decreases the toughness. In this paper, we investigate the minimum degree and the recognizability of minimally $t$-tough graphs in the classes of chordal graphs, split graphs, claw-free graphs, and $2K_2$-free graphs.
Classifying superconductivity in compressed H3S

description: The discovery of high-temperature superconductivity in compressed H3S by Drozdov and co-workers (A. Drozdov, et. al., Nature 525, 73 (2015)) heralded a new era in superconductivity. To date, the record transition temperature of Tc = 260 K stands with another hydrogen-rich compound, LaH10 (M. Somayazulu, et. al., arXiv:1808.07695) which becomes superconducting at pressure of P = 190 GPa. Despite very intensive first-principle theoretical studies of hydrogen-rich compounds compressed to megabar level pressure, there is a very limited experimental dataset available for such materials. In this paper, we analyze the upper critical field, Bc2(T), data of highly compressed H3S reported by Mozaffari and co-workers (S. Mozaffari, et. al., LA-UR-18-30460, DOI: 10.2172/1481108) by utilizing four different models of Bc2(T). In result, we find that the ratio of superconducting energy gap, Δ(0), to the Fermi energy, εF, in all considered scenarios is 0.03 < Δ(0)/εF < 0.07, with respective ratio of Tc to the Fermi temperature, TF, 0.012 < Tc/TF < 0.039. These characterize H3S as unconventional superconductor and places it on the same trend line in Tc versus TF plot, where all unconventional superconductors located.

description: We propose a simple and efficient method for generating metrologically useful quantum entanglement in an ensemble of spin-1 atoms that interacts with a high-finesse optical cavity mode. It requires straightforward preparation of $N$ atoms in the $m_F=0$ sublevel, tailoring of the atom-field interaction to give an effective Tavis-Cummings model for the collective spin-1 ensemble, and a photon counting measurement on the cavity output field. The photon number provides a projective measurement of the collective spin length $S$, which, for the chosen initial state, is heavily weighted around values $S\simeq\sqrt{N}$, for which the corresponding spin states are strongly entangled and exhibit Heisenberg scaling of the metrological sensitivity with $N$, as quantified by the quantum Fisher information.

description: Communication in the internal environment of the enterprise is the primary tool that is used to transmit information, experience, knowledge, standards and principles which represent an essential pillar of the corporate culture and business management. In the current age of competition, businesses are trying their best to keep their position on the market. They are aware of the fact that behind the success of the company is a satisfied customer. And for the customer to be satisfied as well as the company to have positive outcomes – it's necessary for a company to focus some of their activities on the internal communication. Therefore, the aim of this article is to show the importance of internal communication within the organisation, because through the correctly set process of internal communication the company integrates people, communicates targets and its mission – what nowadays is the key to success. Equally, it's an important part of every corporation communication which forms a part of the whole reputation of the organisation or a business.

description: This letter addresses the issue of linearization of quadratic thermal limits of transmission lines for linear OPF formulation. A new irregular polygon based linearization is proposed. The approach is purely based on geometrical concepts and does not introduce any optimization problem. Comparison of the number of constraints is given with different errors for different branch capabilities and systems. Test case analysis is also presented to validate the irregular polygon linearization strategy with optimal value and computational time results.

A set of intermediate equations are obtained. They describe interactions between the small scale (e.g., cellular) structures and the hydrodynamic degrees of freedom. Possible forms of the effective large scale hydrodynamics are constructed and examined. Although a number of different universality classes are allowed by symmetry, numerical results support the simplest scenario, that being the KPZ universality class.

description: To reactivate cacao production in Mesoamerican countries, in the late 2010s the Tropical Agricultural Research and High Education Center (CATIE) started to disseminate 6 cacao clones (CATIE-R1, CATIE-R4, CATIE-R6, PMCT-58, CC-137 and ICS-95) with high production potential, resistance to diseases and good quality. Ten years later, the agronomic and economic performances of these clones were assessed in three regions of Costa Rica (North, Caribbean and Pacific), in order to identify the factors that influence cacao actual yields and family benefits. 
The sample of cacao farms was selected from a list of 267 cacao growers provided by the Ministry of Agriculture. From this list, 30 farmers cultivating the clones were selected (10 per region): half with good yields and half with low yields according to producers' perceptions. Visits to the plantations and inquiries allowed characterizing the socio-economic and agronomic context of the farms and households. Agronomic and agroforestry variables, cacao yields, as well as costs and incomes were measured. Statistical analyses focused on differences among yield classes and on the identification of factors that contribute most to the benefits obtained.
Farms were grouped into four classes of cacao yield. From the first to the fourth class, the yield increased from 268 to 1770 kg/ha, as did the frequency of agronomic practices and application of inputs. Therefore, the production costs also increased according to yield classes but in acceptable levels for smallholders and leading to high cacao yields and incomes (especially classes 2 and 3 with respectively 830 and 1430 kg/ha). Class 4 reported the highest yields but not the highest net incomes due to elevated production costs. The two main agronomic factors that led to higher yields and profits were pruning and fertilization. 
Cacao plantations were between 4 and 10 years old and the shade trees were still in the growth phase. At this age, none of the plantations surpassed 40% of shade cover and other variables of agroforestry structure did not show any influence on clone performance. Another important finding was that there was no genotype x environment interaction in yield results. The three most promising clones were CATIE-R6, CATIE-R4 and CATIE-R1, in this order.
Results reveal that the exploitation of the high productive potential of improved clones must be complemented by an efficient agronomic management. Thus, government agencies and development projects should provide technical support and training to producers in addition to the supply of new varieties, especially clones.

description: Observations of circumstellar disks provide a powerful tool for our understanding of planetary systems dynamics. Analogs to the Solar System asteroid belts, debris disks result from the collision of the remaining solid material of the planet formation process. Even if the presence of disk is now reported for hundreds of stars, its detection around stars similar to the Sun is still very sparse. We report the results of a search for debris disks around Kepler stars with surface physical parameters close to solar values, including rotation period, using observations by the Wide-field infrared Survey Explorer (WISE). From the entire sample of Kepler stars, 881 targets were identified with these parameters and only six of them (KIC 1868785, 7267949, 7435796, 10533222, 11352643, and KIC 11666436) show unambiguous infrared excess, for which we determined debris disk physical parameters. Interestingly, the present study reveals traces of debris disks much more massive and brighter than the Solar System zodiacal dust, probably resulting from recent violent collisional events, orbiting stars with ages around the solar values.

Attention is focused on space-times with a vanishing electric part of the Weyl tensor. It is shown that the only incompressible axistationary magnetic perfect fluid is the interior Schwarzschild solution.

description: Linear mixture models have proven very useful in a plethora of applications, e.g., topic modeling, clustering, and source separation. As a critical aspect of the linear mixture models, identifiability of the model parameters is well-studied, under frameworks such as independent component analysis and constrained matrix factorization. Nevertheless, when the linear mixtures are distorted by an unknown nonlinear functions -- which is well-motivated and more realistic in many cases -- the identifiability issues are much less studied. This work proposes an identification criterion for a nonlinear mixture model that is well grounded in many real-world applications, and offers identifiability guarantees. A practical implementation based on a judiciously designed neural network is proposed to realize the criterion, and an effective learning algorithm is proposed. Numerical results on synthetic and real-data corroborate effectiveness of the proposed method.

description: We investigate the predicted present-day temperature profiles of the hot, X-ray emitting gas in galaxy clusters for two cosmological models - a current best-guess LCDM model and standard cold dark matter (SCDM). Our numerically-simulated "catalogs" of clusters are derived from high-resolution (15/h kpc) simulations which make use of a sophisticated, Eulerian-based, Adaptive Mesh-Refinement (AMR) code that faithfully captures the shocks which are essential for correctly modelling cluster temperatures. We show that the temperature structure on Mpc-scales is highly complex and non-isothermal. However, the temperature profiles of the simulated LCDM and SCDM clusters are remarkably similar and drop-off as $T +AFw-propto (1+-r/a_x)^{-+AFw-delta}$ where $a_x +AFw-sim r_{vir}/1.5$ and $+AFw-delta +AFw-sim 1.6$. This decrease is in good agreement with the observational results of Markevitch et al.(1998) but diverges, primarily in the innermost regions, from their fit which assumes a polytropic equation of state. Our result is also in good agreement with a recent sample of clusters observed by BeppoSAX though there is some indication of missing physics at small radii ($r<0.2 r_{vir}$). We discuss the interpretation of our results and make predictions for new x-ray observations that will extend to larger radii than previously possible. Finally, we show that, for $r>0.2 r_{vir}$, our universal temperature profile is consistent with our most recent simulations which include both radiative cooling and supernovae feedback.

We denote by $ρ_{G/P}$ the associated quasi-regular representation. If G is discrete, these representations are irreducible, but if G is profinite, they split as a direct sum of finite-dimensionalrepresentations $ρ_{G/P_{n+1}}\ominusρ_{G/P_n}$, where P_n is the stabiliser of a level-n vertex in T. For a few concrete examples, we completely split $ρ_{G/P_n}$ in irreducible components. $(G,P_n)$ and $(G,P)$ are Gelfand pairs, whence new occurrences of abelian Hecke algebra.

We extract the correlated wavefunctions, compute the drift and cyclotron currents (due to inhomogeneous density), exhibit the Read operator, and operators that create quasi-particles and holes. We show how the bare kinetic energy can get quenched and replaced by one due to interactions. We find that for $ν=1/2$ the low energy theory has neutral quasiparticles and give the effective hamiltonian and constraints.

description: The presented article explores the effects of TV political advertising on political images of candidates competing in the 2015 presidential election in Poland. For this purpose, the empirical research (N=507) to check the reactions to campaign spots among voters with different political preferences was carried out. The conducted research shows that political preferences significantly affect both the perception of political images and the emotional attitude to candidates. The study also confirms that political advertising has a moderate importance in creating the images of commonly known politicians. Interestingly, the obtained results prove that emotional attitude towards politicians are more permanent and resistant to change under the influence of advertising messages than political image characteristics.

description: More than two decades following the end of civil conflict made possible via Dayton Peace Accords (DPA) instated in 1995, Bosnia-Herzegovina still utilizes this international legal instrument as the sovereign’s official constitution. This paper addresses the impact that the international community’s failure to implement the appropriate locally considerate solutions needed to sustain peacebuilding has left behind. To this end, the paper highlights the quotidian ways in which the socio-cultural landscape of the Bosnian Federation and Republika Srpska remain stratified along ethno-religious divisions. Directing its’ attention on the practical aspects where minorities face discrimination and remain excluded from social spheres the paper calls for a necessary advancement on the human rights protection of safeguarding minority members in both of the country’s de-facto territories. In closing, it argues that society’s schism from the residual consequences of the DPA can be achieved through the practices of change-drivers taking advantage of their training and capacity-building skills in the forms of: inter-ethnic dialogue, inter-cultural reconciliation and inter-religious peace. Constructing competences which demonstrate respect for human rights, encourage co-existence and the equal integration of minority members in society also bear the potential to strengthen the currently fragile relations with the out-group community, reducing a society’s propensity for conflict regression.

description: It was recently shown that the nodal deficiency of an eigenfunction is encoded in the spectrum of the Dirichlet-to-Neumann operators for the eigenfunction's positive and negative nodal domains. While originally derived using symplectic methods, this result can also be understood through the spectral flow for a family of boundary conditions imposed on the nodal set, or, equivalently, a family of operators with delta function potentials supported on the nodal set. In this paper we explicitly describe this flow for a Schrödinger operator with separable potential on a rectangular domain, and determine a mechanism by which lower energy eigenfunctions do or do not contribute to the nodal deficiency.

description: We consider solutions to the 2d Navier-Stokes equations on $\mathbb{T}\times\mathbb{R}$ close to the Poiseuille flow, with small viscosity $ν>0$. Our first result concerns a semigroup estimate for the linearized problem. Here we show that the $x$-dependent modes of linear solutions decay on a time-scale proportional to $ν^{-1/2}|\logν|$. This effect is often referred to as \emph{enhanced dissipation} or \emph{metastability} since it gives a much faster decay than the regular dissipative time-scale $ν^{-1}$ (this is also the time-scale on which the $x$-independent mode naturally decays). We achieve this using an adaptation of the method of hypocoercivity. Our second result concerns the full nonlinear equations. We show that when the perturbation from the Poiseuille flow is initially of size at most $ν^{3/4+}$, then it remains so for all time. Moreover, the enhanced dissipation also persists in this scenario, so that the $x$-dependent modes of the solution are dissipated on a time scale of order $ν^{-1/2}|\logν|$. This transition threshold is established by a bootstrap argument using the semigroup estimate and a careful analysis of the nonlinear term in order to deal with the unboundedness of the domain and the Poiseuille flow itself.

Propagation of singularities for gravity-capillary water waves

Publisher: name: arXiv
Year: 2018
Subjects: subject: Analysis of PDEs (math.AP)

description: We obtain two results of propagation for solutions to the gravity-capillary water wave system. First we show how oscillations and the spatial decay propagate at infinity; then we show a microlocal smoothing effect under the non-trapping condition of the initial free surface. These results extends the works of Craig, Kappeler and Strauss, Wunsch and Nakamura to quasilinear dispersive equations. We also prove the existence of gravity-capillary water waves in weighted Sobolev spaces. Such solutions have asymptotically Euclidean free surfaces. To obtain these results, we generalize the paradifferential calculus of Bony to weighted Sobolev spaces and develop a semiclassical paradifferential calculus. We also introduce a new family of wavefront sets -- the quasi-homogeneous wavefront sets, which is a generalization, at least in the Euclidean geometry, the wavefront sets of Hörmander, the scattering wavefront sets of Melrose, the quadratic scattering wavefront sets of Wunsch and the homogeneous wavefront sets of Nakamura.

Typification notes
Smith & Schubert (1946b: 96) cited a duplicate of J.J. Triana 3038 held in Kew as the type of Begonia maurandiae A.DC. This was not correct as this gathering was not cited in the protologue (de Candolle 1859: 119). We are not aware of any legitimate attempts to lectotypify this name.
Notes
In his account of the Begoniaceae, de Candolle (1864: 279) cited the locality of the syntype W. Jameson 36 (K) as “in Peruviá prope Lloa”. This locality is in Ecuador, and the species is known only from Colombia and Ecuador.

description: Research on proactive work behaviour is increasing, but previous literature reviews remain limited. This study aims to conduct a scoping review of the literature on proactive work behaviour among employees. Using the PRISMA flowchart, articles were sourced from Scopus, Web of Science, and Ebscohost. Eligible publications were empirical studies in English or Indonesian within workplace settings. A total of 196 articles were obtained, analyzed, extracted, and synthesized for the scoping review. The results show that (1) research productivity on proactive work behaviour has risen. Between 2006 and 2024, 196 studies were conducted, with a peak in 2023. China is the leading country in this research area. Methodologically, proactive work behaviour is mostly studied as an independent variable, and the use of multilevel analysis remains limited; (2) the individual task proactivity scale from Griffin et al. (2007) is the most widely used instrument in proactive work behaviour research; and (3) five major theoretical perspectives are frequently employed: social exchange theory, conservation of resources theory, social cognitive theory, self-determination theory, and the broaden-and-build theory. These findings provide a foundation for the future development of research on proactive work behaviour.

description: Temporal data, obtained in the setting where it is only possible to observe one time point per experiment, is widely used in different research fields, yet remains insufficiently addressed from the statistical point of view. Such data often contain observations of a large number of entities, in which case it is of interest to identify a small number of representative behavior types. In this paper, we propose a new method that simultaneously performs clustering and alignment of temporal objects inferred from these data, providing insight into the relationships between entities. Simulations confirm the ability of the proposed approach to leverage multiple properties of the complex data we target such as accessible uncertainties, correlations and a small number of time points. We illustrate it on real data encoding cellular response to a radiation treatment with high energy, supported with the results of an enrichment analysis.

description: Se analizan las características espaciales del Cerrito Colorado de La Ciénaga de Arriba (Departamento de Belén) y la información cronológica generada para el sitio, con el fin de indagar en la experiencia y la percepción del espacio, en el marco de los estudios del paisaje socio-político del Valle de Hualfín para el período de Desarrollos Regionales. Este sitio fue clásicamente asignado a la fase II de la Cultura Belén. El emplazamiento en altura, la visibilidad, la inaccesibilidad y ciertos rasgos defensivos llevan a interpretar al sitio como un poblado protegido, con límites físicos (y simbólicos) para el acceso, como murallas y muros a modo de parapetos. Se sugiere que el Cerrito pudo haber sido ocupado transitoriamente, cuando los pobladores de la zona, dispersos por los campos aledaños, se sentían amenazados. We analyze the spatial characteristics of Colorado Cerrito, La Ciénaga de Arriba (Department of Belén) and the chronological information available for the site. The aim is to investigate the experience and perception under the socio-political landscape`s studies about Hualfín Valley, period of “Regional Developments”. Traditionally, this site was assigned in the phase II of Belén Culture. According to the high altitude, its visibility, the inaccessibility, and defensive features, one can interpret the site as a protected village with physical (and symbolic) boundaries such as walls and parapets. It is also suggested that the Cerrito was perhaps occupied temporarily, when local people, scattered throughout the surrounding fields, felt threatened.

description: This paper gives an overview of the field of clamping and gripping principles from the viewpoint of sample fixturing for dimensional metrology for microobjects. The requirements for clamping microcomponents that allow dimensional measurements are therefore explained before principles and solutions of microclamps as found in literature are reviewed and evaluated on basis of these requirements. Results show that there is no single superior clamping principle or method of implementation but rather several effective solutions for specific applications. The core value of this paper is the link between requirements for sample fixturing in dimensional micrometrology and the many approaches already investigated in the field of microclamping. A radar chart and a decision tree summarize and visualize the major aspects of this review. Finally, directions of future key research areas are suggested.

Contact Injection into Polymer Light-Emitting Diodes

description: The variation of current I with voltage V for poly(phenylene vinylene) and other polymer light-emitting diodes has been attributed to carriers tunneling into broad conduction and valence bands. In actuality the electrons and holes tunnel into polaron levels and transport is by hopping among these levels. We show that for small injection the I-V characteristic is determined mainly by the image force, for large injection by space charge effects, but in both cases the strong variation of mobility with field due to disorder plays an important role.

description: In the present study, a formerly designed Dynamic Micro Tissue Engineering System (DynaMiTES) was applied with our prevalidated human hemicornea (HC) construct to obtain a test platform for improved absorption studies of the anterior eye (Ocular DynaMiTES). First, the cultivation procedure of the classic HC was slightly adapted to the novel DynaMiTES design. The obtained inverted HC was then compared to classic HC regarding cell morphology using light and scanning electron microscopy, cell viability using MTT dye reaction and epithelial barrier properties observing transepithelial electrical resistance and apparent permeation coefficient of sodium fluorescein. These tested cell criteria were similar. In addition, the effects of four different flow rates on the same cell characteristics were investigated using the DynaMiTES. Because no harmful potential of flow was found, dynamic absorption studies of sodium fluorescein with and without 0.005 %, 0.01 % and 0.02 % benzalkonium chloride were performed compared to the common static test procedure. In this proof-of-concept study, the dynamic test conditions showed different results than the static test conditions with a better prediction of in vivo data. Thus, we propose that our DynaMiTES platform provides great opportunities for the improvement of common in vitro drug testing procedures.

description: Electrochemical and equivalent-circuit modelling are the two most popular approaches to battery simulation, but the former is computationally expensive and the latter provides limited physical insight. A theoretical middle ground would be useful to support battery management, on-line diagnostics, and cell design. We analyse a thermodynamically consistent, isothermal porous-electrode model of a discharging lead-acid battery. Asymptotic analysis of this full model produces three reduced-order models, which relate the electrical behaviour to microscopic material properties, but simulate discharge at speeds approaching an equivalent circuit. A lumped-parameter model, which neglects spatial property variations, proves accurate for C-rates below 0.1C, while a spatially resolved higher-order solution retains accuracy up to 5C. The problem of parameter estimation is addressed by fitting experimental data with the reduced-order models.

description: Micro silicon double mirrors have been developed specifically for the design of a novel micro-optical gyroscope. By using wafers with a well-defined angular offset to the (100) plane, an etching angle of 60° can be achieved by wet-chemical etching with KOH. Two likewise structured wafers are connected by means of silicon direct bonding and consequently form 120°double mirrors. A big advantage of these double mirrors is that inaccuracies during assembly onto a micro optical table, such as shifts in the x- and y-direction and twists around the vertical axis are compensated by the mirror and a fixed angle of reflection is maintained. Assembly tolerances for the other two rotational degrees of freedom cannot be compensated in this way yet and a precise rotational alignment of the mirror elements in an optical resonator is still required. Therefore a micro clamping device was developed that can be used in the assembly of a micro-optical gyroscope. The key elements are micro spring structures integrated in the micro-optical table which can be pushed back to allow the insertion of the mirror elements and press the mirrors against two lithographically defined mechanical stops. Various designs of clamping devices were fabricated and their suitability in an optical gyroscope was evaluated.
