FREQUENCY-TUNABLE INTERNAL ANTENNA FOR MOBILE PHONES (2002)

Abstract – New approaches are needed for improving the performance of small antennas to fulfill the multiband operation requirements of future wireless mobile communications terminals. In this paper, a novel low-loss frequency-tuning circuit for mobile handset antennas is proposed. The presented design takes into account several factors that affect the practical mobile handset antenna design, such as the biasing limitations and distortion of the switching component as well as the effect of the mobile handset-sized ground plane. An antenna prototype that is capable of switching between the US cellular and GSM systems at 800-900 MHz frequency range was designed and measured. The antenna was positioned on a metallized printed circuit board (PCB) having size equal to that of a typical mobile phone. The tuning circuit, consisting of transmission line sections and an SPDT (single-pole, double-throw) FET switch, was fabricated directly on the substrate of the PCB. The designed antenna has high radiation efficiency and low distortion in both system bands. 1
Transmission tests of maize mutants induced by ultra-violet radiation (1941)

Brief descriptions are presented for various ultra-violet-induced changes. Among 78 inviable types, the mutant type was recovered in F3 in 71 cases. In several instances the mutant type appeared in low ratios. This tendency was most marked in the segregations for "germless" seeds.\nMale and female transmission tests were made with 24 viable mutant types. In 15 cases the male and female transmission rates were not significantly different. In the remaining nine cases male and female transmission rates were unequal, and in two instances transmission through the male gametophyte was significantly greater than through the female.
Anticancer drug discovery by targeting cullin neddylation (2019)

Protein neddylation is a post-translational modification which transfers the ubiquitin-like protein NEDD8 to a lysine residue of the target substrate through a three-step enzymatic cascade. The best-known substrates of neddylation are cullin family proteins, which are the core component of Cullin-RING E3 ubiquitin ligases (CRLs). Given that cullin neddylation is required for CRL activity, and CRLs control the turn-over of a variety of key signal proteins and are often abnormally activated in cancers, targeting neddylation becomes a promising approach for discovery of novel anti-cancer therapeutics. In the past decade, we have witnessed significant progress in the field of protein neddylation from preclinical target validation, to drug screening, then to the clinical trials of neddylation inhibitors. In this review, we first briefly introduced the nature of protein neddylation and the regulation of neddylation cascade, followed by a summary of all reported chemical inhibitors of neddylation enzymes. We then discussed the structure-based targeting of protein-protein interaction in neddylation cascade, and finally the available approaches for the discovery of new neddylation inhibitors. This review will provide a focused, up-to-date and yet comprehensive overview on the discovery effort of neddylation inhibitors.

Published Evidence Favors the Use of Suprapubic Catheters in Pelvic Colorectal Surgery (2002)

INTRODUCTION: Bladder catheterization is routine during pelvic colorectal surgery, and transurethral catheterization is the norm. However, in gynecologic surgery suprapubic catheters are commonly used and are reported to be superior to urethral catheters. METHODS: A review of published studies comparing urethral and suprapubic catheters in patients undergoing colorectal surgery is presented. Level one evidence from randomized, controlled trials is sparse. Five randomized, controlled trials, most with small numbers, have been published comparing urinary tract infection, urinary retention, duration of catheterization, pain and discomfort, and patient preference. RESULTS: Urinary tract infections were increased in the urethral group in three of the five articles. There were no differences between the two techniques with respect to urinary retention, but all studies commented on the ease with which this complication could be assessed and managed in the suprapubic group. There did not seem to be any difference in duration of catheterization. The suprapubic group experienced less pain and discomfort than the urethral group, and the suprapubic catheter was preferred by those patients who had experienced both. CONCLUSION: The results reported favor suprapubic over urethral catheterization in that urinary tract infections are reduced, particularly in females, and the ability to attempt normal voiding is facilitated, particularly in males.
Novel high-speed transistor based on charge emission from a quantum well (1988)

A novel unipolar transistor employing properties of electrons confined in a single quantum well is proposed. The gate modulation of a charge density in the quantum well results in an exponentially strong variation of the output thermionic emission current to the collector. The device combines the attractive features of both bipolar and field-effect transistors and provides a high speed (2–3 ps intrinsic delay time) with a large current drive (∼105 A/cm2) and high transconductances (1–10 S/mm).
Raman Mapping: Emerging Applications (2017)

Raman mapping is a noninvasive, label‐free technique with high chemical specificity and high potential to become a leading method in biological and biomedical applications. As opposed to Raman spectroscopy, which provides discrete chemical information at distinct positions within the sample, Raman mapping provides chemical information coupled with spatial information. The laser spot scans the investigated sample area with a preset step size and acquires Raman spectra pixel by pixel. The Raman spectra are then discriminated from each other by chemometric analysis, and the end result is a false color map, an image of the sample that contains highly precise structural and chemical information. Raman imaging has been successfully used for label‐free investigations at cellular and subcellular level. Cell compartments, cell responses to drugs and different stages of the cell cycle from the stem cell to the completely differentiated cell were successfully distinguished. This technique is also able to differentiate between healthy and cancer cells, indicating great potential for replacing conventional cancer detection tools with Raman detection in the future.

Molecular phylogeny of species in the genera Amylostereum and Echinodontium (2000)

Analyses of DNA sequences from the internal transcribed spacer (ITS) region of the nuclear rDNA and from a portion of a manganese-dependent peroxidase gene were used to assess the species in Amylostereum, including isolates from the mycangia of horntails, decay, and basidiomes. Four species are recognized: A. areolatum, A. chailletii, A. laevigatum, and A. ferreum. An unidentified Amylostereum isolate from the mycangium of Xoanon matsumurae had an ITS sequence identical to that of A. areolatum. Another unidentified Amylostereum isolate from the mycangium of Sirex areolatus was near A. laevigatum, which appears to be the mycangial symbiont for those horntails attacking cedar-like trees. The other horntail isolates, primarily from Pinaceae, proved to be either A. areolatum or A. chailletii. The DNA sequences of Echinodontium tinctorium, E. tsugicola and E. japonicum were similar to those of the Amylostereum species, and Amylostereum species are now recognized as members of the family Echinodontiaceae rather than the family Stereaceae. Echinodontium taxodii was found to be distinct from the Echinodontiaceae and Stereum, and E. taxodii is recognized as a Laurilia species.
Complications of Renal Transplantation: Evaluation with US and Radionuclide Imaging (2000)

Following renal transplantation, patients are often evaluated with ultrasonography (US) or radionuclide imaging to assess renal function and the presence of possible complications. Both modalities are inexpensive, noninvasive, and nonnephrotoxic. A basic understanding of the surgical techniques commonly used for renal transplantation is useful when imaging these patients in order to recognize complications and to direct further imaging or intervention. The most frequent complications of renal transplantation include perinephric fluid collections; decreased renal function; and abnormalities of the vasculature, collecting system, and renal parenchyma. Perinephric fluid collections are common following transplantation, and their clinical significance depends on the type, location, size, and growth of the fluid collection, features that are well-evaluated with US. Causes of diminished renal function include acute tubular necrosis, rejection, and toxicity from medications. Radionuclide imaging is the most useful modality for assessing renal function. Vascular complications of transplantation include occlusion or stenosis of the arterial or venous supply, arteriovenous fistulas, and pseudoaneurysms. Although the standard for evaluating these vascular complications is angiography, US is an excellent noninvasive method for screening. Other transplant complications such as abnormalities of the collecting system and renal parenchyma are well-evaluated with both radionuclide imaging and US.
The C-terminal tail guides assembly and degradation of membrane proteins (2019)

SUMMARY A large number of newly synthesized membrane proteins in the endoplasmic reticulum (ER) are assembled into multi-protein complexes, but little is known about the mechanisms required for either assembly or degradation of unassembled membrane proteins. We find that C-terminal transmembrane domains (C-TMDs) with shorter tails are inefficiently inserted into the ER membrane since the translation is terminated before they emerge from ribosomes. These TMDs of insufficient hydrophobicity are post-translationally retained by the Sec61 translocon, thus providing a time window for efficient assembly with TMDs from partner membrane proteins. The unassembled C-TMDs are slowly flipped into the ER lumen. While the luminal chaperone BiP captures flipped C-TMDs with long tails and routes them to the ER-associated quality control, C-TMDs with shorter tails are diffused into the nuclear membrane. Thus, our studies suggest that C-terminal tails harbor important biochemical features for both biosynthesis and quality control of membrane protein complexes.
Numerical Modelling Sediment-Bacteria Interaction Processes in the Severn Estuary (2011)

Faecal bacteria exist in both free-living and attached forms in estuarine waters. The deposition of sediments can take faecal bacteria out of the water column and to the bed. The sediments can subsequently be re-suspended to the water column, which can then lead to re-suspension of the faecal bacteria of the attached forms back to the water column. Therefore, the fate and transport of faecal bacteria is highly related to the governing sediment transport processes, particularly where these processes are significant, such as the Severn Estuary, UK. However, little attempt has been made to model such processes in terms of predicting the impact of the sediment fluxes on faecal bacteria levels. Details are given of the refinement of a numerical model of faecal bacteria transport, where the sediment transport processes are significant. After testing the sediment-bacteria interaction model favourably against known results in previous study, the model was applied to the Severn Estuary and Bristol Channel, UK, to investigate the impact of suspended sediment fluxes on the corresponding faecal bacteria transport processes. The model predictions have proved to be encouraging, with the results being compared to a traditional faecal bacteria modelling approach, where sediment bacteria interactions were not included. The new model provides improved predictions of faecal bacteria concentrations when sediment transport is included and for the Bristol Channel Severn Estuary it can be seen that the effects of the sediments on the bacterial levels in the water column can be significant.
Genotoxicity of zearalenone, an estrogenic mycotoxin: DNA adduct formation in female mouse tissues (1995)

Zearalenone is a non-steroidal estrogenic mycotoxin produced by several species of Fusarium which colonize maize, barley, oats, wheat and sorghum and have been implicated in numerous mycotoxicoses in farm animals, especially pigs. In a NTP mouse study a dose-related incidence of hepatocellular adenomas was seen in female mice. A limited number of genotoxicity assays have been conducted with zearalenone. Zearalenone was found to be negative in the Salmonella typhimurium assay. It was also negative in a eukaryotic cell mutation assay with Saccharomyces cerevisae. However, zearalenone and its estrogenic metabolites showed a positive DNA damaging effect in recombination tests with Bacillus subtilis. In this study DNA adducts in female mice and rat treated i.p or orally with zearalenone were determined using a 32P-postlabeling method. Several DNA adducts (12-15) were found in the kidney and liver of female mice treated with a single dose of zearalenone (2 mg/kg i.p. or orally). The total DNA adduct levels reached 114 +/- 37 and 1393 +/- 324 adducts/10(9) nucleotides respectively in kidney and liver after i.p. treatment and 548 +/- 50 adducts/10(9) nucleotides in liver after oral treatment. In mice ovary DNA adducts appeared only after repeated doses (1 mg/kg body wt on days 1, 5, 7, 9 and 10). The total DNA adducts after 10 days in this organ were 17 +/- 5 adducts/10(9) nucleotides. Some adducts were common to all organs. Others were specific to an organ. In contrast, no DNA adducts could be detected in rat organs after i.p. treatment. These results confirm the genotoxicity of zearalenone and its ability to induce hepatocellular adenomas, rather than tumours of genital organs, in mice.
An integrated toolset for engineering software configurations (1988)

Configuration management in toolkit oriented software development environments (SDE), such as the UNIX system, is a long standing nuisance. Mostly, one has to face the choice between poorly or not at all integrated, independent tools, or highly integrated, most specialized, and often language dependent environments. The first choice offers very limited support for a complex task that needs a broad informational basis. The second choice often takes away the programmers' most cherished tools, forces him to adopt some different work discipline, and thereby eventually restricts his creativity. The toolset described in this paper integrates a dedicated version control system and shape, a significantly enhanced Make [Feld79a] program, on the basis of a common object model. This object model comprises multiple versions of software objects as well as conventional file system objects. Taking this approach made it possible to have a sufficiently integrated toolsystem for engineering software configurations while retaining the flexibility of the basic toolbox philosophy, permitting the use of 'off-the-shelf' tools, e.g. editors or compilers.
ViCoMo: visual context modeling for scene understanding in video surveillance (2013)

The use of contextual information can significantly aid scene understanding of surveillance video. Just detecting people and tracking them does not provide sufficient information to detect situations that require operator attention. We propose a proof-of-concept system that uses several sources of contextual information to improve scene understanding in surveillance video. The focus is on two scenarios that represent common video surveillance situations, parking lot surveillance and crowd monitoring. In the first scenario, a pan–tilt–zoom (PTZ) camera tracking system is developed for parking lot surveillance. Context is provided by the traffic sign recognition system to localize regular and handicapped parking spot signs as well as license plates. The PTZ algorithm has the ability to selectively detect and track persons based on scene context. In the second scenario, a group analysis algorithm is introduced to detect groups of people. Contextual information is provided by traffic sign recognition and region labeling algorithms and exploited for behavior understanding. In both scenarios, decision engines are used to interpret and classify the output of the subsystems and if necessary raise operator alerts. We show that using context information enables the automated analysis of complicated scenarios that were previously not possible using conventional moving object classification techniques.
Electron emission from ferroelectrics (2000)

Electron emission from ferroelectrics (FEE) is an unconventional electron emission effect. Methods of FEE excitation are quite different compared to classic electron emission from solids. Two kinds of FEE have been observed, “weak” and “strong.” “Weak” electron emission (current density 10−12–10−7 A/cm2) occurs from polar surfaces of ferroelectric materials in the ferroelectric phase only. A source of the electric field for “weak” FEE excitation is an uncompensated charge, generated by a deviation of macroscopic spontaneous polarization from its equilibrium state under a pyroelectric effect, piezoelectric effect, or polarization switching. The FEE is a tunneling emission current which screens uncompensated polarization charges. It is shown that the FEE is an effective tool for direct domain imaging and studies of electronic properties of ferroelectrics. “Strong” FEE, which is 10–12 orders of magnitude higher than “weak” FEE, achieves 100 A/cm2 and is plasma-assisted electron emission. Two modes of the surface flashover plasma formation followed by strong electron emission have been studied. The plasma of ferroelectric origin has been observed only in the ferroelectric phase and it is induced by polarization switching or a field-enforced phase transition, such as antiferroelectric–ferroelectric or relaxor–ferroelectric. The second mode of plasma is conventional surface flashover which may be initiated by a high voltage application in any phase from any dielectric, including ferroelectrics. In this review paper we consider numerous experimental results, as well as mechanisms of both types of electron emission from ferroelectrics. The main stress is placed on the material aspect in order to clarify the influence of ferroelectricity (ferroelectric phase transitions, polarization switching, etc.) on electron emission. Another aspect which is broadly discussed is the potential applications of these unconventional FEE emitters in various devices for development of high density FEE cathodes for microwave devices, as well as FEE converters of IR irradiation into visible light, x-ray imaging, FEE flat panel displays, etc.
Making Story Time a Literacy Event for the Young Child (1989)

A literacy event is "any action or sequence, involving one or more persons in which the production and/or comprehension of print plays a role" (Anderson, Teale & Estrada, 1980). Story reading by a parent or teacher is perhaps the single most effective literacy event in a young child's experience with written language. Increasingly, reports suggest children's development of skills associated with ease of reading acquisition are enhanced with regular readings of storybooks both prior to and concomitant with formal instruction.
The Physiology of the Tettigoniid Ear (1974)

ABSTRACT The acoustic opening of the large, double prothoracic spiracle gives rise to a vesicula and a trachea which descends into the leg and divides to form the anterior and posterior tympanal air spaces, their apposed walls forming the secondary tympanal membrane. This trachea is independent of the respiratory system. The trachea is exponential or catenoidal in form in the Tettigoniids investigated, and the physics of horns is discussed in relation to the tracheal system. Bilateral recordings from the tympanal nerves have shown that blocking the spiracular opening eliminates the response to a sound signal at an intensity of 45 dB. Unilateral recordings during the blocking and reopening of both the spiracle and the tympanal slits has shown that at a sound intensity of 47·5 dB a response is obtained from the tympanal organ only when the sound is directed at an open spiracle; blocking the spiracle eliminates the response. Threshold curves for the ‘spiracle’ and for the ‘tympanal slits’ show a sensitivity difference of between 2 dB and 25 dB, the difference varying with frequency. The implications of this finding are discussed.
Multilayered metal core-shell nanostructures for inducing a large and tunable local optical field (2005)

We examine the near-field optical properties of multilayered metal core-shell sphere nanostructures by extending the Mie theory, and demonstrate that the local-field enhancement can be increased by adding new metal shells. A local intensity enhancement of more than ${10}^{5}$ times can be obtained in the cavity between the Ag core and the innermost Ag shell for proper configurations of multilayered Ag core-shell spheres. The high enhancement can be tuned from the red to the infrared region by varying the configurations of the core-shell nanostructures.
Enabling Secure and Efficient Video Delivery Through Encrypted In-Network Caching (2016)

In-network content caching has been a natural trend in emerging network architectures to handle the exponential growth of video traffic. However, due to the potentially wide attacking surfaces, caching video content in the increasingly untrusted networked environment inevitably raises new concerns on user privacy exposure and unauthorized video access. Existing encrypted protocols like HTTPs either fall short of fully leveraging in-network caching or require decrypting the traffic in the middle without guaranteeing the end-to-end security. In this paper, we present a new networked system for efficient encrypted video delivery while preserving the benefits of in-network caching. As video chunks are encrypted before distribution, we first design a compact, efficient, yet encrypted video fingerprint index to empower the network with a fully controlled capability of locating the cached encrypted chunks for given encrypted requests. We then explain how to deploy the encrypted design in our proposed architecture and present a secure redundancy elimination protocol to enable fast video delivery via leveraging cached encrypted chunks. We further discuss the full support of cache management, adaptive video delivery, and video access control. Rigorous analysis and prototype evaluations demonstrate the security, efficiency, and effectiveness of the design.
