Extremely Red Objects (EROs) are characterized by their red optical-infrared colors (e.g., R-Ks > 5.0), which would be caused by either dusty star formation or old stellar population at moderate to high redshifts. We combine deep optical (Subaru R) and near-infrared (CFHT Ks) observations obtained as part of the Subaru $GTO2deg^2$ survey to select EROs over this field and to explore their properties. We present number densities of EROs as a function of magnitudes. We are planning to quantify the environments for EROs and to see if EROs reside in overdense regions.

Myelolipoma in the mediastinum is an extremely rare entity. In this report, we present the case of a 79-year-old asymptomatic man who had three bilateral paravertebral mediastinal tumors. The three tumors were resected simultaneously using bilateral three-port video-assisted thoracoscopic surgery (VATS). There has been no evidence of recurrence within four years after the operation. Multiple bilateral mediastinal myelolipomas are extremely rare. There are no reports in the English literature of multiple bilateral thoracic myelolipomas that were resected simultaneously using bilateral VATS. We also present characteristic features of myelolipomas, which are helpful for diagnosis.

This study investigates display station physical adjustments preferred by a sample of visual display terminal operators. Participants in the study were selected to assure representation of extremely short and extremely tall persons, as well as persons of midrange physical stature. Individual operators were led through a step-by-step sequence to determine their preferred initial settings of seat height, keyboard height and slope angle, and CRT height and tilt angle. Each operator then performed a brief text input tase, after which final preferred adjustments were measured. Intermeasure correlation strongly suggest that "flat" (low slope angle) keyboards are in appropriate for short operators who select low seat heights. In addition, the keyboard angle adjustments preferred by most operators substantially exceed a current German ergonomic display station requirement.

This paper introduces a novel sensor network protocol, R-WSLP(Realtime Wireless Sensor Line Protocol), which has extremely low latency characteristic in large-scale WSN. R-WSLP is proposed to implement realtime forest fire monitoring system. We propose Distributed TDMA method for the multiple channel access and Time Synchronized Forwarding Mechanism instead of routing technique to achieve low latency network. Also, R-WSLP provides extremely low power operation which we accomplished by reducing idle listening. In our experimentation, we get successful results at the forest fire monitoring system with our protocol.

This paper addresses the assessment methods used to evaluate the magnetic exposure of a human to ELF EMF (Extremely Low Frequency Electromagnetic Field) which is caused by the process of power delivery from 60 Hz commercial power. These days the main concern is primarily focused on the magnetic field. For the exposure assessment, both numerical studies and laboratory experiments were studied and the results of the two compared for methodological suitability. The numerical analyses employ the Impedance Method (IM), Boundary Element Method (BEM), and Finite Element Method (FEM) and the laboratory experiments used various human phantom models made with conductivities congruent to human organs and then exposed to uniform/non-uniform magnetic fields to produce eddy currents. Under these conditions a number of examples have been evaluated and the reliability assessed to present the pros and cons of each methodology.

In wireless access networks, it is extremely important to provide high quality of real time and interactive services, including voice and video traffic. Furthermore, low latency communication is shifting toward new paradigm which enhances user's high quality of experience, meeting the requirements for specific applications such as tactile internet, remote-control robot and machines, and mission critical application. In this paper, we introduce the approaches to achieve the extremely low latency service. The approaches include the core requirements and the key technologies providing low latency communication maintaining high reliability in wireless access networks.

Neuropathic shoulder arthropathy or Charcot's shoulder is an extremely rare disease, and sometimes it is associated with cervical syringomyelia. Clinical symptoms of the disease include edema of the shoulder and restriction in range of motion. Radiological diagnosis can be made through plain radiography through a characteristic, atrophic destruction of the joint. We experienced a Charcot's joint of the shoulder wherein destruction of the joint progressed extremely quickly and reviewed the literature concerning this condition.
