Wireless Inference-based Notification (WIN) without Packet Decoding

We consider ultra-energy-efficient wireless transmission of notifications in sensor networks. We argue that the usual practice where a receiver decodes packets sent by a remote node to acquire its state or message is suboptimal in energy use. We propose an alternative approach where a receiver first (1) performs physical-layer matched filtering on arrived packets without actually decoding them at the link layer or higher layer, and then (2) based on the matching results infers the sender's state or message from the time-series pattern of packet arrivals. We show that hierarchical multi-layer inference can be effective for this purpose in coping with channel noise. Because packets are not required to be decodable by the receiver, the sender can reach a farther receiver without increasing the transmit power or, equivalently, a receiver at the same distance with a lower transmit power. We call our scheme Wireless Inference-based Notification (WIN) without Packet Decoding. We demonstrate by analysis and simulation that WIN allows a sender to multiply its notification distance. We show how senders can realize these energy-efficiency benefits with unchanged system and protocols; only receivers, which normally are larger systems than senders and have ample computing and power resources for WIN-related processing.Engineering and Applied Science

Compressed Statistical Testing and Application to Radar

We present compressed statistical testing (CST) with an illustrative application to radar target detection. We characterize an optimality condition for a compressed domain test to yield the same result as the corresponding test in the uncompressed domain. We demonstrate by simulation that under high SNR, a likelihood ratio test with compressed samples at 3.3x or even higher compression ratio can achieve detection performance comparable to that with uncompressed data. For example, our compressed domain Sample Matrix Inversion test for radar target detection can achieve constant false alarm rate (CFAR) performance similar to the corresponding test in the raw data domain. By exploiting signal sparsity in the target and interference returns, compressive sensing based CST can incur a much lower processing cost in statistical training and decision making, and can therefore enable a variety of distributed applications such as target detection on resource limited mobile devices.Engineering and Applied Science

Hemoptysis From a Ruptured Mycotic Aneurysm Caused by Salmonella

SummaryAlthough an uncommon cause of hemoptysis, fistulas between the aorta and the airway (especially the left bronchopulmonary tree) are frequently associated with infected aneurysms of the thoracic aorta and are fatal if not diagnosed and surgically treated. We report a case of mycotic aneurysm in a 74-year-old man who presented with hemoptysis. This patient complained of blood-tinged sputum and chest pain initially, and the chest X-ray showed an aortic aneurysm. The chest computed tomography scan revealed the aneurysm ruptured into the lung parenchyma. Urgent graft replacement was performed successfully after diagnosis. Tissue culture yielded nontyphoidal Salmonell

Collaborative Integration between IT Industry and Logistics Industry in Taiwan: A Case Study on T Company\u27s E-Logistics Plan

The IT industry is Taiwan’s most thoroughly globalized industry. In the IT industry, suppliers and customers are spread all over the world, so making logistics management more efficient is very important. With government’s sponsorship, Taiwan’s IT industry has introduced e-Procurement (Plans A and B) to make the whole procurement process among enterprises an electronic one. Thus e-Procurement became the fundamentals of e-SCM. In order to extend the benefits of e-procurement, Taiwan government continuously promote the IT industry to introduce e-Logistics (Plan D). The objectives of this paper are to study the collaborative integration between IT industry and logistics industry in Taiwan, and to investigate the progress of introducing e-Logistics into the IT industry. A PC manufacturer, T Company was selected for use in the case study. It was found that the logistics visibility elevation through “Track and Trace” and the achievement of VMI (Vendor Managed Inventory) are the objectives of e-Logistics implementation. IT manufacturers worked out common business models. Then each supply chain can follow the common specification and implement their e-Logistics individually. This study found that not only the IT manufacturers gain the competitive advantages, but LSPs (Logistics service providers) also learn from collaborative commerce and provide better service for customers with the implementation of e-Logistics. Then eight guidelines were induced as the reference for other industries to implement e-Logistics afterward. Besides, some suggestions were proposed to IT industry, logistics industry, and government

The Effectiveness of Traditional Chinese Medicine in Treating Patients with Leukemia

Leukemia is the most common malignancy among all childhood cancers and is associated with a low survival rate in adult patients. Since 1995, the National Health Insurance (NHI) program in Taiwan has been offering insurance coverage for Traditional Chinese Medicine (TCM), along with conventional Western medicine (WM). This study analyzes the status of TCM utilization in Taiwan, in both pediatric and adult patients with leukemia. A retrospective cohort study was conducted using population-based National Health Insurance Research Database of Registry of Catastrophic Illness, involving patient data from 2001 to 2010 and follow-up data through 2011. The effectiveness of TCM use was evaluated. Relevant sociodemographic data showed that both pediatric and adult patients who were TCM users one year prior to leukemia diagnosis were more likely to utilize TCM services for cancer therapy. A greater part of medical expenditure of TCM users was lower than that of TCM nonusers, except little discrepancy in drug fee of adult patients. The survival rate is also higher in TCM users. Altogether, these data show that TCM has the potential to serve as an adjuvant therapy when combined with conventional WM in the treatment of patients with leukemia

Complete classification of steerability under local filters and its relation with measurement incompatibility

Quantum steering is a central resource for one-sided device-independent quantum information. It is manipulated via one-way local operations and classical communication, such as local filtering on the trusted party. Here, we provide a necessary and sufficient condition for a steering assemblage to be transformable into another via local filtering. We characterize the equivalence classes with respect to filters in terms of the steering equivalent observables (SEO), first proposed to connect the problem of steerability and measurement incompatibility. We provide an efficient method to compute the extractable steerability that is maximal via local filters and show that it coincides with the incompatibility of the SEO. Moreover, we show that there always exists a bipartite state that provides an assemblage with steerability equal to the incompatibility of the measurements on the untrusted party. Finally, we investigate the optimal success probability and rates for transformation protocols (distillation and dilution) in the single-shot scenario together with examples

Phosphorous Diffuser Diverged Blue Laser Diode for Indoor Lighting and Communication.

An advanced light-fidelity (Li-Fi) system based on the blue Gallium nitride (GaN) laser diode (LD) with a compact white-light phosphorous diffuser is demonstrated for fusing the indoor white-lighting and visible light communication (VLC). The phosphorous diffuser adhered blue GaN LD broadens luminescent spectrum and diverges beam spot to provide ample functionality including the completeness of Li-Fi feature and the quality of white-lighting. The phosphorous diffuser diverged white-light spot covers a radiant angle up to 120(o) with CIE coordinates of (0.34, 0.37). On the other hand, the degradation on throughput frequency response of the blue LD is mainly attributed to the self-feedback caused by the reflection from the phosphor-air interface. It represents the current state-of-the-art performance on carrying 5.2-Gbit/s orthogonal frequency-division multiplexed 16-quadrature-amplitude modulation (16-QAM OFDM) data with a bit error rate (BER) of 3.1 × 10(-3) over a 60-cm free-space link. This work aims to explore the plausibility of the phosphorous diffuser diverged blue GaN LD for future hybrid white-lighting and VLC systems
