A Medium-Resolution Near-Infrared Spectral Library of Late Type Stars: I
We present an empirical infrared spectral library of medium resolution
(R~2000-3000) H (1.6 micron) and K (2.2 micron) band spectra of 218 red stars,
spanning a range of [Fe/H] from ~-2.2 to ~+0.3. The sample includes Galactic
disk stars, bulge stars from Baade's window, and red giants from Galactic
globular clusters. We report the values of 19 indices covering 12 spectral
features measured from the spectra in the library. Finally, we derive
calibrations to estimate the effective temperature, and diagnostic
relationships to determine the luminosity classes of individual stars from
near-infrared spectra.
This paper is part of a larger effort aimed at building a near-IR spectral
library to be incorporated in population synthesis models, as well as, at
testing synthetic stellar spectra.Comment: 34 pages, 12 figures; accepted for publication at ApJS; the spectra

Future Facilities Summary
For the session on future facilities at DIS09 discussions were organized on
DIS related measurements that can be expected in the near and medium - or
perhaps far - future, including plans from JLab, CERN and FNAL fixed target
experiments, possible measurements and detector upgrades at RHIC, as well as
the plans for possible future electron proton/ion colliders such as the EIC and
the LHeC project.Comment: Summary of the parallel sessions on future facilities and the plenary
discussion session on possible future electron proton/ion colliders such as
the EIC and the LHeC project at the Deep Inelastic Scattering workshop in

Future neutrino oscillation facilities
The recent discovery that neutrinos have masses opens a wide new field of
experimentation. Accelerator-made neutrinos are essential in this program.
Ideas for future facilities include high intensity muon neutrino beams from
pion decay (`SuperBeam'), electron neutrino beams from nuclei decays (`Beta
Beam'), or muon and electron neutrino beams from muon decay (`Neutrino
Factory'), each associated with one or several options for detector systems.
Each option offers synergetic possibilities, e.g. some of the detectors can be
used for proton decay searches, while the Neutrino Factory is a first step
towards muon colliders.
A summary of the perceived virtues and shortcomings of the various options,
and a number of open questions are presented.Comment: Originally written for the CERN Strategy Grou
Multi-Facilities in a Shared Space as a Spatial Design Strategy of Kollektiv Hotel Bandung
The classification of hotel as a part of travel and accommodation facilities nowadays has become flexible since the emergence of thematic hotels and hotels with specific design concepts. One of the distinguished hotels in Bandung that has quickly gained its popularity is Kollektiv Hotel. With the score of 9.0 (out of 10) on Traveloka since offered into the market, Kollektiv Hotel does not seem to provide much space in order to make their guests impressed, as well as to meet the formal requirements as regulated by the government. With only as much area as the site for a house in the upper-class neighborhood, this hotel could meet the government’s requirements for a three-star hotel. It indicates that this hotel has applied a very effective spatial design that is worth reviewing for further study. Thus, this paper explores the spatial arrangement and layout in Kollektiv Hotel to discover the design strategy performed by this hotel. It is concluded that Kollektiv Hotel provides many shared spaces that serve multi-facilities and are open for both public and hotel guests.

Shortcuts through Colocation Facilities
Network overlays, running on top of the existing Internet substrate, are of
perennial value to Internet end-users in the context of, e.g., real-time
applications. Such overlays can employ traffic relays to yield path latencies
lower than the direct paths, a phenomenon known as Triangle Inequality
Violation (TIV). Past studies identify the opportunities of reducing latency
using TIVs. However, they do not investigate the gains of strategically
selecting relays in Colocation Facilities (Colos). In this work, we answer the
following questions: (i) how Colo-hosted relays compare with other relays as
well as with the direct Internet, in terms of latency (RTT) reductions; (ii)
what are the best locations for placing the relays to yield these reductions.
To this end, we conduct a large-scale one-month measurement of inter-domain
paths between RIPE Atlas (RA) nodes as endpoints, located at eyeball networks.
We employ as relays Planetlab nodes, other RA nodes, and machines in Colos. We
examine the RTTs of the overlay paths obtained via the selected relays, as well
as the direct paths. We find that Colo-based relays perform the best and can
achieve latency reductions against direct paths, ranging from a few to 100s of
milliseconds, in 76% of the total cases; 75% (58% of total cases) of these
reductions require only 10 relays in 6 large Colos.Comment: In Proceedings of the ACM Internet Measurement Conference (IMC '17),

Geographic Availability of Assistance Dogs: Dogs Placed in 2013-2014 by ADI- or IGDF-Accredited or Candidate Facilities in the United States and Canada, and Non-accredited U.S. Facilities.
Assistance dogs' roles have diversified to support people with various disabilities, especially in the U.S. Data presented here are from the U.S. and Canada non-profit facilities (including both accredited and candidate members that fulfilled partial requirements: all here termed "accredited") of Assistance Dogs International (ADI) and the International Guide Dog Federation (IGDF), and from non-accredited U.S. assistance dog training facilities, on the numbers and types of dogs they placed in 2013 and 2014 with persons who have disabilities. ADI categories of assistance dogs are for guide, hearing, and service (including for assistance with mobility, autism, psychiatric, diabetes, seizure disabilities). Accredited facilities in 28 states and 3 provinces responded; accredited non-responding facilities were in 22 states and 1 province (some in states/provinces with responding accredited facilities). Non-accredited facilities in 16 states responded. U.S./Canada responding accredited facilities (55 of 96: 57%) placed 2,374 dogs; non-accredited U.S. facilities (22 of 133: 16.5%) placed 797 dogs. Accredited facilities placed similar numbers of dogs for guiding (n = 918) or mobility (n = 943), but many more facilities placed mobility service dogs than guide dogs. Autism service dogs were third most for accredited (n = 205 placements) and U.S. non-accredited (n = 72) facilities. Psychiatric service dogs were fourth most common in accredited placements (n = 119) and accounted for most placements (n = 526) in non-accredited facilities. Other accredited placements were for: hearing (n = 109); diabetic alert (n = 69), and seizure response (n = 11). Responding non-accredited facilities placed 17 hearing dogs, 30 diabetic alert dogs, and 18 seizure response dogs. Non-accredited facilities placed many dogs for psychiatric assistance, often for veterans, but ADI accreditation is required for veterans to have financial reimbursement. Twenty states and several provinces had no responding facilities; 17 of these states had no accredited facilities. In regions lacking facilities, some people with disabilities may find it inconvenient living far from any supportive facility, even if travel costs are provided. Despite accelerated U.S./Canada placements, access to well-trained assistance dogs continues to be limited and inconvenient for many people with disabilities, and the numerous sources of expensive, poorly trained dogs add confusion for potential handlers
