Abstract

A 73-year-old woman having a throat lump sensation and dysphagia for the past several months presented at our otorhinolaryngology outpatient clinic. A physical examination disclosed a protruding subepithelial mass over the right tonsil fossa. The mass was not tender and had no mucosal lesions or signs of active infection. Therefore, we arranged face and neck computed tomography scans, which reported a solitary osseous lesion over the anterior-right aspect of the C1-2 joint. Considering the rarity and unfamiliar anatomy of this disease, we built a 3D-printed model to assist with the surgical rehearsal of the procedure as well as with a preoperation discussion with the patient and her family. We arranged a combined Otolaryngology-Neurosurgery department approach after discussion with the neurosurgeon and successfully removed the lesion without sacrificing the overlying longus capitis muscle. The pathology examination revealed no evidence of malignancy. The final diagnosis was cervical spine solitary osteochondroma. The patient had a complete recovery of both oral cavity and normal swallowing function. No tumor recurred during the 3-year follow-up. On the basis of this case, in-house 3D-printing technology can offer a rapid, reliable model for an interdisciplinary team to use to enhance personalized presurgical planning, thus providing better patient engagement during hospitalization.

Abstract

Recently, CAO et al. proposed an efficient electronic voting scheme based on the polynomial function. They claimed to satisfy the fairness, uniqueness, eligibility, anonymous, accuracy and robustness. In this paper, we show that the electronic voting can guarantee neither robustness nor anonymity. Some candidate can add the ballot number by altering data, and any candidate can know the accurate content of each vote after the tallying stage.

Abstract

This paper demonstrates a new force sensing nano-probe that allows a cost effective nano-tip to be easily assembly on a tuning fork sensor. By taking advantages of surface micromachined tip fabrication, the subsequent assembly-transfer procedures are able to minimize the mass load effect of a tuning fork based atomic force microscopy (AFM). Furthermore, the micro assembly transfer of nano-probes can also be achieved to manufacture devices in an easy way and to mount the probe precisely. This approach is compatible with CMOS process and able to integrate micromachined probes into an alternative host chip.

Abstract

The atomic force microscope (AFM) is a newly developed high resolution microscopy technique which is capable of measuring of nano-scale pattern, nanofabrication, data storage and material analysis in the mechanical, chemical and biological fields. The nano-probe is the most critical component of the AFM, and it consists of three parts: a sharp tip, a cantilever beam and a supporting base. The tip must be sharp enough to measure the surface topography with a high resolution. The cantilever beam must have the appropriate spring constant and resonant frequency for the type of operation selected. The supporting base must be of a suitable size for loading into the probe head. Therefore, depending on the various applications, the nano-probe structures used in the AFM should must meet the following criteria: (1) good tip sharpness with a small radius apex, (2) small spring constant and (3) high resonant frequency. This research will propose the design rule for three types of nano-probes, including the rectangular-shaped, V-shaped and chamfer V-shaped nano-probe for the AFM using the finite element method. The fundamental mechanical parameters of a nano-probe for an AFM are its spring constant, its resonant frequency and its physical dimensions. Research of the relevant literatures indicates that numerous researchers only consider the small deflection theory when analyzing the above-mentioned physical properties of the nano-probe. However, the small deflection theory is suitable only when the behavior of nonlinear geometry has not taken place in the structure. But, the applications of the nano-probe are increasing at a rapid rate, and the geometric dimensions or physical properties of nano-probe are changing from the traditional applications. The measuring of the red corpuscle requires a small size probe, but the ultra-high resolution topography is demanding an ever increasing applied force. The phenomenon of nonlinear geometry is occurring in the structure at present, and as a result the small deflection theory is no longer suitable for analyzing the nano-probe. This research introduces the large deflection theory in the finite element method (FEM) to investigate the geometrical size and the physical properties of the nano-probe.Copyright © 2004 by ASME
