Protein Nanopatterns by Oxime Bond Formation (2010)

Patterning proteins on the nanoscale is important for applications in biology and medicine. As feature sizes are reduced, it is critical that immobilization strategies provide site-specific attachment of the biomolecules. In this study, oxime chemistry was exploited to conjugate proteins onto nanometer-sized features. Poly(Boc-aminooxy tetra(ethylene glycol) methacrylate) was synthesized by free radical polymerization. The polymer was patterned onto silicon wafers using an electron beam writer. Trifluoroacetic acid removal of the Boc groups provided the desired aminooxy functionality. In this manner, patterns of concentric squares and contiguous bowtie shapes were fabricated with 150-170-nm wide features. Ubiquitin modified at the N-terminus with an α-ketoamide group and N(ε)-levulinyl lysine-modified bovine serum albumin were subsequently conjugated to the polymer nanopatterns. Protein immobilization was confirmed by fluorescence microscopy. Control studies on protected surfaces and using proteins presaturated with O-methoxyamine indicated that attachment occurred via oxime bond formation.
Fabrication and evaluation of single mode fibres (1980)

The homogeneous chemical vapour deposition technique, normally used for the manufacture of multimode fibres, has been applied to the fabrication of low loss monomode fibres for operation in the 0.6 to 1.6 µm region. The process enables fibres having cores based on phosphosilicate, germanosilicate, and silica glasses to be drawn in lengths up to 5 km. Because an appreciable amount of energy lies outside the core, a low loss cladding of borosilicate glass must also be deposited. A detailed description of the preform deposition and characterisation is presented, and the fibre drawing process is outlined. Core diameters range between 4 and 10 µm for single mode operation in the 0.6 to 1.5 µm region, whilst the index difference between core und cladding is typically 0.3 %. Losses of 1.5 dB/km have been achieved at 1.06 µm. Fibre characterisation by observation of the far field radiation pattern yields V value, core diameter, and index difference directly. An alternative technique involving loss measurements over a range of wavelengths about the cut off point is prone to serious inaccuracy. &lt;br/&gt;&lt;br/&gt;Finally, single mode fibres with extremely low birefringence (less than 3°/m linear retardance) have been developed for instrumentation applications.
Using data on digital cellular and PCS voice networks (2002)

Many new digital cellular and personal communications services (PCS) networks that provide both voice and data communication capabilities are being installed in the United States and around the world. Current cellular and PCS handsets primarily target voice telephony, but the next generation will also support data services. In this paper we review the current offerings in wireless handsets that support both voice and data services and also present our design for a next-generation wireless handset. We discuss the tradeoffs in selecting an operating system and input device, and in designing a user interface. The physical design of our user interface and the wired network infrastructure support applications such as telephone directory, electronic mail, and Web browsing. The result is a small, user-friendly handset featuring handwriting recognition, foldable video graphics adapter (VGA)-sized liquid crystal display (LCD) screens, and the Inferno™ operating system.

Structural characteristics via SLDV for a class of morphing micro-air-vehicles (2007)

Conventional control surfaces have been used in most carbon fiber composite, membrane-wing autonomous micro air vehicles (MAV). In some cases, vehicle morphing is achieved using servo actuators to articulate vehicle kinematic joints, or to deform crucial wing / tail surfaces. However, articulated lifting surfaces and articulated wing sections are difficult to instrument and fabricate in a repeatable fashion. Assembly is complex and time consuming. The goal of this paper is to establish the feasibility of morphing wings on autonomous MAVs that are actuated via active materials. Active actuation is achieved via a type of piezoceramic composite called Macro Fiber Composite (MFC). This paper investigates the structural dynamics of morphing wings on MAVs that are actuated via active composites. This paper continues the work presented in<sup>1</sup> by considering structural dynamic characteristics of the morphing vehicle determined through Scanning Laser Doppler Vibrometry (SLDV).
Validation of Criteria for Selective His Bundle and Para‐Hisian Permanent Pacing (2006)

The above criteria enabled SHBP and PHP to be validated easily and clearly. A longer follow-up will be needed in order to ascertain whether the clinical outcome of these two approaches differs.
Difference in Brain Densities Between Chronic Alcoholic and Normal Control Patients (1981)

The densities of the brains of 11 chronic alcoholics were compared with those of 11 age-matched normal control subjects. Densities were determined from the density numbers generated by computerized tomography at three levels of the brain-the highest level of the lateral ventricles and the next two higher levels-with adjustments made to control for possible artifacts in the data. The advantage of the dominant hemisphere over the nondominant hemisphere was lessened in alcoholics.
Evolution of Browning in Apple during CA storage: A Proteomics Approach (2012)

During long term storage of apple, physiological disorders may occur. One major group of internal disorders is characterized by flesh browning. The susceptibility to flesh browning is cultivar, batch and season dependent and is caused by a combination of pre and post harvest factors. An important influencing factor is the controlled atmosphere (CA) storage of apple. The main objective of this experiment is to investigate how the proteome changes during storage. This will be related to the real browning incidence after prolonged storage, which was determined by picture analysis. Apples (Malus x domestica Borkh., cv. Braeburn) were picked in the orchard of the Experimental Garden for Pome and Stone Fruits, pcfruit (Sint-Truiden, Belgium) at three different harvest times. Proteins were extracted immediately
Practical SQUID instrument for nondestructive testing (1997)

We report on the development of a scanning eddy-current imaging system designed to detect deep subsurface flaws in conducting materials. A high transition temperature (high-Tc) superconducting quantum interference device (SQUID) magnetometer is employed to provide the required sensitivity at low frequencies, while a combination of small cylindrical high-Tc superconducting and μ-metal shields enable the instrument to be scanned in a magnetically noisy environment, rather than the object under test. The shields are arranged to prevent unwanted excitation and ambient noise fields from reaching the SQUID, and to enhance spatial resolution and minimize undesirable edge effects. Thus far, the instrument has successfully detected cracks and pits through 10 layers of aluminum, with a combined thickness of 5 cm at room temperature.
Antennes imprimees alimentees par lignes triplaques : application a des reseaux pour telecommunications spatiales (1993)

Cette these comprend l'analyse theorique d'une structure pouvant comprendre un ou deux elements rayonnants alimentes par une fente decoupee dans le plan de masse superieur d'une ligne triplaque. La methode d'analyse utilisee necessite la determination des fonctions de green des milieux stratifies et la resolution d'un systeme d'equations integrales de reaction dans le domaine spectral a l'aide d'une methode des moments. Le logiciel elabore a partir de cette methode a ete valide par differentes maquettes. La mise en reseau de telles structures rayonnantes a permis d'obtenir des antennes blindees possedant un faible niveau de polarisation croisee sur une large bande passante en en particulier une antenne fonctionnant en double polarisation lineaire constituee par deux sous-reseaux imbriques dont les elements rayonnants sont des grilles polarisantes. Un autre aspect de ce travail est l'etude d'elements rayonnants fonctionnant en double polarisation lineaire. Diverses structures ont ete realisees et une antenne originale possedant d'excellentes performances en isolation, bande passante et decouplage entre polarisations est presentee. Ce travail se termine par l'etude et la realisation d'elements rayonnants fonctionnant en polarisation circulaire et satisfaisant aux besoins des antennes pour telecommunications par satellite avec les mobiles. Un reseau plan egalement destine a ce type de mission est presente. Ce dernier est realise a l'aide d'un nouveau type d'element rayonnant compact a plusieurs resonateurs paralleles
Trapping Phosphorus in Runoff with a Phosphorus Removal Structure (2012)

Reduction of phosphorus (P) inputs to surface waters may decrease eutrophication. Some researchers have proposed filtering dissolved P in runoff with P-sorptive byproducts in structures placed in hydrologically active areas with high soil P concentrations. The objectives of this study were to construct and monitor a P removal structure in a suburban watershed and test the ability of empirically developed flow-through equations to predict structure performance. Steel slag was used as the P sorption material in the P removal structure. Water samples were collected before and after the structure using automatic samples and analyzed for total dissolved P. During the first 5 mo of structure operation, 25% of all dissolved P was removed from rainfall and irrigation events. Phosphorus was removed more efficiently during low flow rate irrigation events with a high retention time than during high flow rate rainfall events with a low retention time. The six largest flow events occurred during storm flow and accounted for 75% of the P entering the structure and 54% of the P removed by the structure. Flow-through equations developed for predicting structure performance produced reasonable estimates of structure "lifetime" (16.8 mo). However, the equations overpredicted cumulative P removal. This was likely due to differences in pH, total Ca and Fe, and alkalinity between the slag used in the structure and the slag used for model development. This suggests the need for an overall model that can predict structure performance based on individual material properties.
Recent Trends in Biodiesel and Biogas Production (2018)

Biodiesel and biogas are two very important sources of renewable energy worldwide, and particularly in the EU countries. While biodiesel is almost exclusively used as transportation fuel, biogas is mostly used for production of electricity and heat. The application of more sophisticated purification techniques in production of pure biomethane from biogas allows its delivery to natural gas grid and its subsequent use as transportation fuel. While biogas is produced mostly from waste materials (landfills, manure, sludge from wastewater treatment, agricultural waste), biodiesel in the EU is mostly produced from rapeseed or other oil crops that are used as food, which raises the 'food or fuel' concerns. To mitigate this problem, considerable efforts have been made to use non-food feedstock for biodiesel production. These include all kinds of waste oils and fats, but recently more attention has been devoted to production of microbial oils by cultivation of microorganisms that are able to accumulate high amounts of lipids in their biomass. Promising candidates for microbial lipid production can be found among different strains of filamentous fungi, yeast, bacteria and microalgae. Feedstocks of interest are agricultural waste rich in carbohydrates as well as different lignocellulosic raw materials where some technical issues have to be resolved. In this work, recovery and purification of biodiesel and biogas are also considered.

FTS3‐01‐05: FURTHER ANALYSES OF COGNITIVE OUTCOMES IN THE APECS PHASE‐3 TRIAL OF VERUBECESTAT IN PRODROMAL AD (2019)

In the phase-3 APECS trial, the BACE inhibitor verubecestat failed to improve clinical outcomes in participants with prodromal AD and was associated with worsening on some measures, notably cognition. Worsening relative to placebo was apparent early but did not progress further over time. We performed analyses to evaluate whether this early-onset worsening of cognition was consistent across participant subgroups and cognitive domains, and the possible relationship with adverse events. Participants aged 55–85 years who had memory impairment and elevated brain amyloid but without significant functional impairment were randomized in a double-blind, placebo-controlled, 104-week trial of verubecestat 12mg and 40mg. Cognition was assessed by the ADAS-Cog13 and a 3-domain composite cognition score (CCS-3D) which included tests of episodic memory, executive function, and attention/processing speed. Analyses were exploratory and intended to be hypothesis-generating. As previously reported, total score on the ADAS-Cog13 and CCS-3D worsened in each verubecestat group relative to placebo at the earliest evaluation time point of Week-13. There was no observed effect of age, baseline severity, APOE4 genotype, use of AD treatment at baseline, PET brain amyloid load, or MRI brain volume on treatment response on the ADAS-Cog13 at Week-13. There did not appear to be a relationship among groupings of adverse events (e.g. those potentially related to cognition, psychiatric adverse events, or falls) within the first 13 weeks and treatment response on the ADAS-Cog13 at Week-13. Analysis of components of CCS-3D suggested that the Week-13 verubecestat worsening relative to placebo was driven by worse scores on episodic memory and attention/processing speed domains. In contrast, verubecestat was associated with better performance on letter and category fluency tests in the executive function domain at Week-13. The early-onset worsening of cognition by verubecestat in participants with prodromal AD was consistent across subgroups and did not appear to be influenced by adverse events. Verubecestat appeared to have differential effects on different cognitive domains at Week-13, but this could be a chance finding given the large number of exploratory comparisons performed. If replicated in other data sets, this observation might provide insights into the role of BACE inhibition in cognition.
A Note on an Authentication Technique Based on Distributed Security Management for the Global Mobility Network (1998)

In this paper, we analyse the authentication protocol that has been proposed for the so called global mobility network in the October issue of the IEEE Journal on Selected Areas in Communications. Using a simple logic of authentication, we show that the protocol has flaws, and we present three different attacks that exploit these. We correct the protocol using a simple design tool that we have developed. 1 Introduction In a recent issue of the IEEE Journal on Selected Areas of Communications, an authentication technique has been proposed for use in the so called global mobility network (GLOMONET), which provides a personal communication user with global roaming service [SN97]. The proposed authentication technique consists of two phases: Corresponding author. ffl the roaming-service-setup phase, in which authentication to set up the roaming-service environment is performed by the visited (roamed) network, the home network, and the roamer, and ffl the roaming-service-provision phas...
Plasma-assisted wafer de-chucking (power-lift) process induced charging damage (2002)

Charging damage from plasma-enhanced dielectric deposition has been well known for many years. The mechanism involved, however, is still not fully understood. A common practice in plasma processing of insulated films, both for dielectric deposition and etching, is to neutralize residual charges in the film with low-power plasma at the end while the wafer is being lifted for unloading. This is done to prevent unexpected movement of the wafer due to electrostatic force, which can lead to wafer crashing during unloading. It was reported that this final plasma-assisted wafer de-chucking (power-lift) step could cause significant damage (Cheung et al, 1997). The combination of charging damage during deposition and power-lift causes very severe damage to the gate-oxide. In most reported studies of charging damage during plasma enhanced dielectric deposition, whether or not the power-lift has been part of the process is not specified. Such uncertainty would complicate attempts to construct a model for the damage mechanism. The power-lift process is still widely used in both dielectric deposition and etching processes, but there have been no reports on power-lift induced charging damage to date. In many situations, it is still desirable to have a power-lift process. We therefore studied the power-lift process using damage as a response to find a low-damage power-lift condition.

21대 총선과 2021년 보궐선거의 승패 결정 요인과 정치적 함의 (2021)

이 글은 2020년 21대 국회의원 총선과 2021년 서울·부산 광역단체장 보궐선거 결과를 분석하면서 승패 결정 요인과 그 속에 내포된 정치적 함의를 살펴보았다. 두 선거는 정치세력들 사이에 정반대의 승패 결과를 보였는데, 두 선거 모두 각 세력의 전략적 선택이 중대한 승패 요인으로 작용했다. 양대 진영 모두 진영논리가 극단에 이른 상황 속에서, 과거에는 지지층 결속의 전략이 우선이었다면, 두 선거는 스윙 보터(swing voter)를 견인하는 전략이 승패에 더 중대한 요인으로 등장하였다. 이를 위해서는 각각의 정치세력 내부에서 강력한 응집력을 가진 강경파를 어떻게 효과적으로 통제하느냐가 관건이 되었다. 이런 연구는 기존에 이루어진 몇 가지 연구 가설들, 즉 ①회고적 평가 투표의 시각, ②이슈의 역할을 중심으로 보는 시각, ③당파적 지형을 중심으로 보는 시각이 제한적 타당성만을 가지며, 전략적 선택의 시각으로 그 한계들을 보완해야 한다고 주장한다.
