Interface challenges
For example, when one of the authors contacted a ministry of health for more detailed epidemiological data, the data were offered with a five-page data request form that significantly restricted use and sharing of the data. Furthermore, it stated that it would take “up to three months” to be released because of the rev...

Abstract
We present the first scattered-light images of two debris disks around the F8 star HD 104860 and the F0V star HD 192758, respectively $\sim45$ and $\sim67$ pc away. We detected these systems in the F110W and F160W filters through our re-analysis of archival Hubble Space Telescope NICMOS data with modern starlight subtr...

Introduction
Debris disks are extrasolar system components evolving around main-sequence stars. They are composed of kilometer-sized planetesimals formed during the earlier protoplanetary stage of the system, and of dust particles generated by colliding bodies through a destructive grinding cascade stirred by secular perturbations ...

Introduction
Using the measured radii of a sample of Herschel-resolved disks, interestingly showed that the typical grain size in these disks does not directly scale with the radiative pressure blowout particle size, but decreases with stellar luminosity. This may indicate that other mechanisms are at work in debris disks that limi...

The data on HD 104860 and HD 192758 were obtained as part of two surveys with the near-IR NICMOS instrument on HST that aimed at resolving a selection of debris disks identified from their infrared excess, respectively with the Spitzer Space Telescope (HST-GO-10527, PI: D.

Discussion
These two detections add to a growing population of debris disks resolved in scattered light. To date, 41 of such have been imaged around stars from \sim 10 Myr to a few Gyr, over a large range of spectral types (See Fig. REF ). Yet, considering the numerous attempts to image debris disks around systems with large infr...

These combined results seem to indicate that there is an underlying population of debris disks much fainter than the population of bright debris disks discovered so far, indicative of low scattering albedos.

Conclusion
To conclude, we have detected two debris disks in scattered-light, around HD 104860 and HD 192758. The former disk has previously been imaged in thermal emission with Herschel but never in scattered-light, and the latter disk has never been imaged before. These disks were found in archival HST-NICMOS data in the near-i...

Abstract
This paper addresses an estimation problem of an additive functional of $\phi$, which is defined as $\theta(P;\phi)=\sum_{i=1}^k\phi(p_i)$, given $n$ i.i.d. random samples drawn from a discrete distribution $P=(p_1,...,p_k)$ with alphabet size $k$.

Lower Bound Analysis
We here describe lower bound analyses and prove the lower bound of thm:optimal-rate-1-3/2,thm:optimal-rate-3/2. First, we prove the \frac{1}{n} term, which is accomplished by applying the LeCam's two point method with appropriate construction of two probability vectors. The precise claim is given by the following theor...

Discussion
In this paper, we reveal that the divergence speed characterizes the minimax optimal rate for \alpha \in (1,3/2) and \alpha \in [3/2,2]. Combining the previous result in DBLP:journals/corr/FukuchiS17, the minimax rate is characterized by the divergence speed for any \alpha \in (0,2] except \alpha = 1. The Shannon entro...

Abstract
In this paper we list all possible degrees of a faithful transitive permutation representation of the group of symmetries of a regular map of types $\{4,4\}$ and $\{3,6\}$ and we give examples of graphs, called CPR-graphs, representing some of these permutation representations.

Introduction
The classification of highly symmetric objects, particularly regular maps and polytopes, is a problem that attracts both geometers and algebraists. The idea of using permutation representations to classify regular maps and polytopes is not new but in 2008 the concept of a graph associated with a regular polytope, calle...

Introduction
The problem is extensible to regular hypertopes of rank 4 with toroidal rank 3 residues and we strongly believe that CPR graphs of regular toroidal maps may play an important role in the classification of regular hypertopes with toroidal rank 3 residues. Indeed, the group theoretical conditions for an incidence system ...

Toroidal regular maps
Consider the regular tessellations of the plane by identical squares, triangles or hexagons. These tesselations are infinite regular 3-polytopes whose full symmetry groups are the Coxeter groups [4, 4], [3,6] or [6,3], respectively, generated by three reflections \rho _0,\, \rho _1,\rho _2, as shown in Figures REF and ...
