A subband algorithm for real-time autofocusing of SAR images (2005)

Presents an autofocusing algorithm for real-time synthetic aperture radar (SAR) processing. The algorithm is based on the fact that time shifts between subband SAR images represent the phase errors due to motion errors during the flight of the radar platform. The subband SAR images are generated by subband decomposition of the high-resolution high-contrast area of a complex SAR image. The successive steps of the subband algorithm have low complexity compared to conventional autofocus algorithms and can be implemented efficiently in hardware.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Multiple description coding approach for Internet video delivery (2002)

This work proposes and implements a system to transmit in real-time slow video signals - in particular video conference signal, that is head and shoulder sequences - over the public network. The proposed codec is based on a multiple description approach that gives N equally important and independent flows. The advantage of this codec is an intrinsic robustness to the transmission errors and to the packet loss, as the simulation results have proved. This feature results very suitable not only for IP-network, but also for every packet network like the next generation mobile systems. The approach is important also for the end user scalability since each device can decide the information to receive according to the resolution of the display and the bandwidth of the connecting link using the same source data stream.
From Virus Structure to Chromatin: X-ray Diffraction to Three-Dimensional Electron Microscopy (2010)

Early influences led me first to medical school with a view to microbiology, but I felt the lack of a deeper foundation and changed to chemistry, which in turn led me to physics and mathematics. I moved to the University of Cape Town to work on the X-ray crystallography of some small organic compounds. I developed a new method of using molecular structure factors to solve the crystal structure, which won me a research studentship to Trinity College Cambridge and the Cavendish Laboratory. There I worked on the austenite-pearlite transition in steel. This is governed by the dissipation of latent heat, and I ended up numerically solving partial differential equations. I used the idea of nucleation and growth during the phase change, which had its echo when I later tackled the assembly of Tobacco mosaic virus (TMV) from its constituent RNA and protein subunits. I wanted to move on to X-ray structure analysis of large biological molecules and obtained a Nuffield Fellowship to work in J.D. Bernal's department at Birkbeck College, London. There, I met Rosalind Franklin, who had taken up the study of TMV. I was able to interpret some of Franklin's beautiful X-ray diffraction patterns of the virus particle. From then on, my fate was sealed. After Franklin's untimely death in 1958, I moved in 1962 to the newly built MRC Laboratory of Molecular Biology in Cambridge, which, under Max Perutz, housed the original MRC unit from the Cavendish Laboratory. I was thus privileged to join the Laboratory at an early stage in its expansion and consequently able to take advantage of, and to help build up, its then unique environment of intellectual and technological sophistication. There I have remained ever since.
Amalgam--resurrection and redemption. Part 2: The medical mythology of anti-amalgam. (2001)

Mercury-containing amalgam restorative material has come under attack for its alleged harmful effects on systemic health. A literature search revealed that amalgam restorations release small quantities of mercury but apparently not enough to cause systemic health problems. Mercury from dental amalgam restorations cannot be linked to kidney damage, Alzheimer's disease, multiple sclerosis, other central nervous system diseases, "amalgam disease," mental disorders, damage to the immune system, increases in antibiotic resistance, or harmful reproductive effects. Dentists occupationally exposed to mercury have not been shown to suffer harmful reproductive or other systemic health effects, provided proper mercury hygiene is used. There are legitimate health concerns about alternative restorative materials, including resin composite. According to the latest scientific information available, dental amalgam remains a safe and effective restorative material.

Growth of 3’’ diameter Gd3Ga5O12 crystals (1978)

As the bubble technology has progressed from the research stage into pilot plant operation, the need for larger diameter substrates has developed. Today, typical 3 in. diameter crystals of GGG weigh between 9000 and 10 000 grams and are grown from charges of 12 000 grams or more. The growth of 3 in. diameter GGG crystals with low defect densities 1(?/cm2) presents several problems which are not encountered during the growth of small diameter crystals. The first problem encountered is one of proper scaling of the growth furnace and growth parameters. The second problem is that of melt composition to insure a uniform lattice parameter throughout the entire crystal. A third area which can present problems is the size and mass of the charge required for 3 in. diameter crystals. Each of the parameters and their relationship to crystal imperfections is discussed.
Kinetic Art: A Mural of Variably Stressed Photoelastic Material with Light Polarizers (1973)

A prototype mural, whose construction will be of interest to artists and architects, was made in 1972 at Cornell University from materials commonly used to analyze stresses in models of mechanical parts and structures by means of polarized light [1]. The mural, in the form of a ? in. thick, 12 x 7.5 ft. panel is shown in Fig. 1 as installed in the lobby of the Cornell Engineering Library about two feet in front of a large window. Sunlight illuminates it for viewers in the lobby during the day and interior electric light, for viewers outside the building at night. A cross section of the construction of the mural is shown in Fig. 2. The mural is suspended from the ceiling of a room, so that it hangs freely within a few inches from the floor. Two angle irons are attached at the lower edge and a false floor is laid between the angle irons and parallel supports eight feet away. (The installation shown in Fig. 1 has the false floor only on the lobby side of the mural.) The weight of a viewer on the false floor causes the mural to be stretched and, as he walks along, the local stresses in the mural to change, giving rise to a composition in which patterns and colors vary, that is, one has a kinetic picture (Fig. 3, cf. color plate). The mural is made of a sandwich construction
PCR 기반의 무세포 단백질 발현 시스템을 이용한 절단 트랜스아미나제의 고속생산 (2006)

In this work, we attempted the application of cell-free protein synthesis technology for the rapid generation of truncated enzymes. Truncated DNAs of a transaminase were PCR-amplified and directly expressed in cell-free protein synthesis reactions. Variants of the transaminase were rapidly prepared and analyzed for their enzymatic activity. Described method that combines the PCR and cell-free protein synthesis technologies will offer a versatile platform for the rapid generation of optimally modified protein species.

Short text understanding through lexical-semantic analysis (2015)

Understanding short texts is crucial to many applications, but challenges abound. First, short texts do not always observe the syntax of a written language. As a result, traditional natural language processing methods cannot be easily applied. Second, short texts usually do not contain sufficient statistical signals to support many state-of-the-art approaches for text processing such as topic modeling. Third, short texts are usually more ambiguous. We argue that knowledge is needed in order to better understand short texts. In this work, we use lexical-semantic knowledge provided by a well-known semantic network for short text understanding. Our knowledge-intensive approach disrupts traditional methods for tasks such as text segmentation, part-of-speech tagging, and concept labeling, in the sense that we focus on semantics in all these tasks. We conduct a comprehensive performance evaluation on real-life data. The results show that knowledge is indispensable for short text understanding, and our knowledge-intensive approaches are effective in harvesting semantics of short texts.
Dermacentor albipictus (Acari, Ixodidae) on Captive Reindeer and Free-ranging Woodland Caribou (1990)

Infestations of winter ticks (Dermacentor albipictus) on two captive reindeer (Rangifer tarandus tarandus) are reported and may be associated with increased grooming and alopecia. Over 400,000 ticks were recovered from one reindeer. Few ticks (less than 25 ticks/animal) were found on three free-ranging woodland caribou (Rangifer tarandus caribou).
Mining landfills for space and fuel (1993)

Lancaster County, Pennsylvania`s experiments with landfill reclamation are helping the county remain self-sufficient in managing its solid waste stream. Landfill mining is proving to be a worthwhile approach to extending landfill life and obtaining fuel for the county`s waste-to-energy plant.
A Dynamic Programming Approach To Length-Limited Huffman Coding (2008)

The ``state-of-the-art'' in Length Limited Huffman Coding algorithms is the $Θ(ND)$-time, $Θ(N)$-space one of Hirschberg and Larmore, where $D\le N$ is the length restriction on the code. This is a very clever, very problem specific, technique. In this note we show that there is a simple Dynamic-Programming (DP) method that solves the problem with the same time and space bounds. The fact that there was an $Θ(ND)$ time DP algorithm was previously known; it is a straightforward DP with the Monge property (which permits an order of magnitude speedup). It was not interesting, though, because it also required $Θ(ND)$ space. The main result of this paper is the technique developed for reducing the space. It is quite simple and applicable to many other problems modeled by DPs with the Monge property. We illustrate this with examples from web-proxy design and wireless mobile paging.
Polarization mode dispersion compensation for 10 Gbps over single mode fiber (2001)

The application of high-speed data transmission at a bit rate B>10 Gbps, through a single mode optical fiber (SMF) subject to polarization mode dispersion (PMD), is addressed in this paper. Two methods are proposed and compared for the mitigation of the induced and performance limiting intersymbol interference (ISI): the computationally simpler method of nonlinear threshold compensation (NLC), vs. the more complex but better performing method of maximum-likelihood sequence estimation (MLSE).
Multipolarized Reader Antenna With Periodic Units Based on Electric Field Coupling for UHF RFID Near-Field Applications (2019)

This paper presents a multipolarized reader antenna with periodic units based on electric field coupling for near-field applications of ultra-high frequency (UHF) radio frequency identification (RFID). The antenna units are composed of two branches that are mirror-symmetric with respect to the x-axis and produce ±45° linear polarization. A 90° phase difference is produced between the upper and lower branches by introducing a phase shifter into the upper branch, so that the near-field electric fields excited in the horizontal plane exhibit a quasi-circular polarization distribution. The proposed design is validated by simulations and experiments using prototype 4-unit and 6-unit antennas. The proposed antennas can generate strong and uniform electric fields and provide reading volumes of 400 mm × 320 mm × 300 mm and 560 mm × 320 mm × 300 mm for the 4-unit and 6-unit antennas, respectively, regardless of the orientation of the tags in the horizontal plane. In addition, the far-field gain is low with a maximum of -6 dBi, thus the misreading of tags outside the reading region is avoided. The proposed antenna achieves impedance matching over the Chinese UHF RFID band (920-925 MHz) and therefore meets the application requirements of near-field RFID reader antennas.
Synthesis, purification, properties and characterization of sorted single-walled carbon nanotubes (2018)

Single-walled carbon nanotubes (SWCNTs) have attracted significant attention due to their outstanding mechanical, chemical and optoelectronic properties, which makes them promising candidates for use in a wide range of applications. However, as-produced SWCNTs have a wide distribution of various chiral species with different properties (i.e. electronic structures). In order to take full advantage of SWCNT properties, highly purified and well-separated SWCNTs are of great importance. Recent advances have focused on developing new strategies to effectively separate nanotubes into single-chirality and/or semiconducting/metallic species and integrating them into different applications. This review highlights recent progress in this cutting-edge research area alongside the enormous development of their identification and structural characterization techniques. A comprehensive review of advances in both controlled synthesis and post-synthesis separation methods of SWCNTs are presented. The relationship between the unique structure of SWCNTs and their intrinsic properties is also discussed. Finally, important future directions for the development of sorting and purification protocols for SWCNTs are provided.
Alendronate Adherence and Its Impact on Hip-Fracture Risk in Patients With Established Osteoporosis in Taiwan (2011)

A pharmacoepidemiology study was conducted using the health insurance database in Taiwan to assess compliance with osteoporosis drug regimens and the impact of compliance on the risk for secondary fractures. Patients >50 years of age with vertebral/hip fracture who had been started on alendronate therapy for the first time only after the fracture were included. Compliance was measured using the medication possession ratio (MPR) and was included as a time-dependent covariate in the Cox model to compare the difference between compliant (MPR ≥ 80%) and noncompliant patients (MPR <80%) with respect to risk for subsequent hip fractures. Only 38% of the study population remained compliant during the first year of treatment. Over the 4-year follow-up period, the risk of hip fracture among the compliant patients was 70% lower than that among the noncompliant ones (adjusted hazard ratio (HR) 0.30). Among patients with osteoporosis in Taiwan who had experienced a fracture and had started alendronate therapy, compliance with the dosage regimen was suboptimal. It was also found that compliance significantly reduced the risk of secondary hip fracture up to 4 years.
“Grand Entrance Hall,” Back Door or Foundation Stone? the Role of Constitutional Principles in Construing and Applying the Constitution of Canada (2001)

The ship of state is run and governed by a most difficult mechanism of rules, principles, precedents and administrative wheels.Without a thorough knowledge of this complicated machinery, there is not much use in trying to direct its course in a proper channel and a correct way.
The extracellular matrix and transforming growth factor-β1: Tale of a strained relationship (2015)

Physiological tissue repair aims at restoring the mechano-protective properties of the extracellular matrix. Consequently, redundant regulatory mechanisms are in place ensuring that tissue remodeling terminates once matrix homeostasis is re-established. If these mechanisms fail, stromal cells become continuously activated, accumulate excessive amounts of stiff matrix, and fibrosis develops. In this mini-review, I develop the hypothesis that the mechanical state of the extracellular matrix and the pro-fibrotic transforming growth factor (TGF)-β1 cooperate to regulate the remodeling activities of stromal cells. TGF-β1 is stored in the matrix as part of a large latent complex and can be activated by cell contractile force that is transmitted by integrins. Matrix straining and stiffening lower the threshold for TGF-β1 activation by increasing the mechanical resistance to cell pulling. Different elements of this mechanism can be pharmacologically targeted to interrupt the mechanical positive feedback loop of fibrosis, including specific integrins and matrix protein interactions.
A BRITISH COMMONWEALTH MEDICAL CONFERENCE (1948)

self-sufficiency. As with the body, so with the specialist group, co-ordinated team work is essential and the whole is at the mercy of its weakest part. It is a revealing metaphor and indi- cates that specialization is the price of evolution, not only biologically, but in the social and pro- fessional spheres as well.
Peripheral Neural Mechanisms Determining the Orientation of Cylinders Grasped by the Digits (1998)

When a human grasps a cylindrical object, feedback on the orientation of the cylinder with respect to the axes of the digits is crucial for successful manipulation of the object. We measured the ability of humans to discriminate the orientations of cylinders passively contacting the fingerpad. For a cylinder of curvature of 521 m-1 (radius, 1.92 mm) subjects were able to discriminate, at the 75% level, orientation differences of 5.4 degrees; for a less curved cylinder (curvature, 172 m-1; radius, 5.81 mm) the difference limen decreased to 4.2 degrees. The neural mechanisms underlying the determination of tactile orientation were investigated by recording the responses of single slowly adapting type I afferents (SAIs) innervating the fingerpads of anesthetized monkeys. When cylinders were stepped across the receptive field of an SAI, the resulting response profiles were Gaussian in shape; the shape corresponded to the shape of the cylinder, increasing in height and decreasing in width for more curved cylinders. All SAIs had the same underlying profile shape except for a multiplicative constant determined by the sensitivity of the individual afferent. Thus it was possible to reconstruct the response of the population of active SAIs in the fingerpad. Changing the orientation of the cylinder resulted in a rotation of the population response, but the change in angle of the population response was greater than the change in orientation of the cylinder. This discrepancy increased as the orientation of the cylinder moved closer to the orientation of the axis of the finger and was more pronounced for the less curved cylinder. Measured contact areas between the cylinders and the skin were elliptical, with orientations exceeding those of the cylinder; again the differences were greater for the less curved cylinder and for orientations closer to that of the finger axis. The human discrimination performance could be explained in terms of the SAI population responses.
