We consider the problem of partitioning clinical services in hospitals into groups with the goal of efficiently allocating existing inpatient beds. At the strategic level, there are two major possibilities: pooling versus focusing. Pooling the bed capacity allows one to achieve an overall high occupancy level for a fixed number of beds. On the other hand, focusing by dividing the capacity into groups...
Remote patient monitoring systems (RMS) have gained increasing popularity in recent years. RMS have great potential to improve medical services by providing more affordable, timely, and accessible care. This paper describes an effective low-cost RMS that is readily deployable. The system targets chronic disease patients and attempts to reduce patient visits to the hospital and healthcare costs. The...

Recently, many applications for co-operative Intelligent Transportation System (C-ITS) using wireless vehicle communication technology such as DSRC have been developed to improve traffic problems and provide user convenience. Above all, broadcast message sets such as CAM and DENM are very useful for vehicle safety. However, V2X systems must design system parameters in highly congested traffic conditions,...
Z2-FET, a partially gated diode, was explored for ESD application due to its sharp switching behavior [1,2]. 1T-DRAM application of Z2-FET has recently been evidenced [3,4] leading to an even stronger interest for this device. However, a deep explanation of physical phenomena involved in Z2-FET operation has not been proposed yet. In this paper, we pro-vide a detailed description of the Z2-FET DC...
The field distributions of various modes in rectangular waveguides filled with uniaxial media are presented. The presented cases include aligned cases when the optic axis is parallel to one of the coordinate axes and the tilted cases when the optic axis is not parallel to any of the coordinate axes but still lies within one of the two side-wall planes. In the aligned uniaxial-z case the analytical...
We present a hybrid fiber link to realize the local two-way optical frequency comparison with self-synchronization. It enables us to detect round-trip fiber noise and one-way fiber noise, and estimate the residuals. Moreover, we can check, to the best of our knowledge for the first time, the reciprocity of the accumulated noise forth and back over a bi-directional fiber, and also evaluate the noise...
We present a frequency comb-assisted experimental setup which enables us to both coherently transfer the stability and accuracy of a remote near-infrared (NIR) ultrastable laser to a mid-infrared (MIR) quantum cascade laser (QCL), and widely tune the QCL frequency for spectroscopic applications. The QCL is stabilized at the level of 2×10−15 from 1 to 100 s, with an accuracy of 10−14 after 100 s. The...
The Fermi level of graphene in contact with the metal contact is a critically important factor for graphene-based device design. Fermi level pinning like behavior at the metal on a graphene can limit the contact resistance reduction and other device operations, especially in high workfunction metal cases. We report that this problem can be substantially alleviated by the hydrogen anneal at high pressure...
This paper presents the fabrication and testing of a novel Electric Cell-substrate Impedance Spectroscopy (ECIS) biosensor. This is the first time when ECIS electrodes were fabricated on a stretchable polydimethylsiloxane (PDMS) substrate and ECIS measurements on mammalian cells exposed to cyclic strain of 4% and 8% were performed. The stretchable ECIS biosensors simulate in vitro the dynamic environment...
RF-CMOS process employing 14nm FinFET technology is introduced for the first time and its RF performance is characterized. Compared with its 28nm planar counterpart, the optimized 14nm RF FinFET consumes 63% of DC power with 53% of device active area and 3.8 times higher intrinsic gain (gm/gds). Based on the 14 nm technology, VNCAP with higher cap density (8%) and Q-factor (23%) is also verified for...
Lag compensation is widely implemented in shooter games to mitigate the impact of network latency. “Shot around a corner” is an inconsistency introduced by lag compensation that still exists in many recent titles. In this paper, we investigate the influence of network latency and movement speeds on the rollback distances, and how they in turn affect the perceived “shot around a corner” frequencies...
This paper presents a high throughput photosensitive polymer cantilever device for real time monitor of drug-induced cardiac toxicity screening. The cantilever device comprises micro-grooves and 3×3 microelectrode array on top of its surface. The optimized micro-grooves facilitate alignment of cardiomyocytes and thus greatly increase the contraction force generated by the cardiomyocytes. Furthermore,...
Lateral implanted SiC MOSFETs and NMOS capacitors were fabricated and used to extract channel mobility and interface state density DIT for three different gate oxides. DIT values were extracted using the high(1 MHz)-low(1 kHz) method for NMOS capacitors and the subthreshold slope for MOSFETs. The subthreshold slope extraction gave 6–20 times higher DIT values compared to the high-low method, presumably...
The unidirectional propagation of signals is the key to modern electronic logic circuits and fundamental applications such as a diode, isolator, gyrator, and circulator.
Currently, MnZn ferrite and NiZn ferrite have been widely used as magnetic shielding materials for WPC operating in the frequency range of 100∼205 kHz.
We review the operation mechanisms of the Z2-FET underlining its attractiveness as a capacitorless DRAM memory. The main parameters that govern the memory performance are discussed based on systematic experiments and simulations.
