Bessel-beam representation for partially coherent fields (1995)

The Bessel-beam representation for partially coherent fields is introduced as an alternative to the familiar angular spectrum representation. This alternative representation is applied to far fields generated by partially coherent secondary sources, nondiffracting partially coherent fields, and statistically homogeneous fields. A scheme for generating nondiffracting partially coherent fields is also discussed.
Anaplastic large cell lymphoma: one or more entities among T‐cell lymphoma? (2009)

Anaplastic large cell lymphoma (ALCL) is a subtype of peripheral T-cell lymphoma (PTCL) first described in 1985 as a lymphoid malignancy characterized by marked cellular pleomorphism, propensity to grow cohesively, tendency to invade lymph node sinuses and diffuse expression of CD30 1. The discovery of the t(2;5), involving the anaplastic lymphoma kinase (ALK) gene on chromosome 2 and the nucleophosmin (NPM) gene on chromosome 5 in the majority of systemic ALCL, has soon pointed out that ALCL is a clinically and biologically heterogeneous disease. While ALK-positive (ALK+) ALCL is usually characterized by onset in children and young adults and better prognosis, epidemiology, poor outcome and possibly genetic defects of ALK-negative (ALK-) ALCL suggest that this neoplasms should be considered an independent pathological entity. The aim of this review is to illustrate clinical features, histology, immunophenotype, genetics and biology of ALCL and discuss possible relationship(s) among different T-non-Hodgkin lymphoma (T-NHL).

Bis(4-cobaltoceniumyl-1-ferrocenyl-3-methyl-1,2,3-triazolylidene)gold(I) hexafluoridophosphate–trifluoromethanesulfonate (1.2/1.8) (2018)

The title compound, [AuCo 2 Fe 2 (C 5 H 5 ) 4 (C 13 H 11 N 3 ) 2 ](PF 6 ) 1.2 (CF 3 SO 3 ) 1.8 , was synthesized by deprotonation of 4-cobaltoceniumyl-1-ferrocenyl-3-methyl-1,2,3-triazolium hexafluoridophosphate trifluoromethanesulfonate with thallium ethoxide, followed by transmetalation with chlorido(triphenylphosphine)gold(I), crystallizing as orange prisms. It is a unique example of a homoleptic dimetallocenyl-substituted triazolylidene complex.
Performance Analysis of a Bit Mapper of the Dual-Polarized MIMO DVB-T2 System (2013)

초고해상도의 비디오와 다채널 오디오를 통한 극사실적인 방송 서비스를 지향하는 UHDTV (Ultra-High Definition TeleVision)가 차세대 방송 표준으로 논의되고 있으나 기존의 지상파 방송 시스템의 데이터 전송률이 UHDTV 방송 서비스의 요구 전송률에 크게 미치지 못하기 때문에 새로운 지상파 방송 시스템의 개발 또는 현재 시스템의 전송률 증가에 대한 연구가 필요한 상황이다. 이를 위해 기존의 DVB-T2 (Digital Video Broadcasting-2nd generation Terrestrial) 시스템에 고차 성상 변조 및 이중 편파 안테나를 이용한 다중 입출력 시스템을 적용하여 데이터 전송량을 증가시키는 연구가 진행되고 있다. 비정규 LDPC (Low-Density Parity Check) 부호를 사용하는 DVB-T2에 기반한 다중 입출력 시스템의 성능을 최적화하기 위해, 다중 입출력 시스템을 위한 최적의 비트 매퍼 설계에 대한 연구가 필요하다. 그러나 현재까지 진행되어 온 비트 매퍼 설계는 단일 입출력 시스템에 대해 국한되어 있다. 따라서 본 논문에서는 다중 입출력 시스템의 위한 최적의 비트 매퍼를 설계하기 위한 사전 연구로, 이중 편파 다중 입출력 시스템의 VND (Variable Node Degree) 분포를 나타내는 파라미터를 새롭게 정의하고 정의된 파라미터에 따른 시스템의 수신 성능을 분석하였다. The UHDTV system, which provides realistic service with ultra-high definite video and multi-channel audio, has been studied as a next generation broadcasting service. Since the conventional digital terrestrial transmission system is not capable to cover the increased transmission data rate of the UHDTV service, there are great necessity of researches about increase of data rate. Accordingly, the researches has been studied to increase the transmission data rate of the DVB-T2 system using dual-polarized MIMO technique and high order modulation. In order to optimize the MIMO DVB-T2 system where irregular LDPC codes are used, it is necessary to study the design of the bit mapper that matches the LDPC code and QAM symbols in MIMO channel. However, the research related to the design of the bit mapper has been limited to the SISO system. Therefore, this paper defines a new parameter that indicates the VND distribution of MIMO DVB-T2 system and performs the performance analysis according to the parameter which will be helpful for designing a MIMO bit mapper.
The Craniocaudal Extension of Posterolateral Approaches and Their Combination (2010)

The combination of the far-lateral and simple retrosigmoid approaches significantly increases the petroclival working area and access to the cranial nerves. However, risk of injury to neurovascular structures and time needed to extend the craniotomy must be weighed against the increased working area and angles of attack.

CO Adsorption Behavior of Cu/SiO2, Co/SiO2, and CuCo/SiO2 Catalysts Studied by in Situ DRIFTS (2012)

The mode of CO adsorption is an important factor in directing the selectivity of CO hydrogenation toward methanol, hydrocarbons, or higher alcohols. Here, we report results on three catalysts: Cu/SiO2, Co/SiO2, and CuCo/SiO2. Infrared spectroscopic studies on Cu/SiO2 and CuCo/SiO2 show similar CO adsorption behavior on copper sites, in terms of adsorption frequency and stability, regardless of the presence or absence of cobalt. The CO species adsorbing on copper is not thermally stable at typical CO hydrogenation reaction temperatures. For CO to adsorb on cobalt sites on either Co/SiO2or CuCo/SiO2, temperatures above ambient are required. In general, linearly adsorbed CO binds more strongly to the cobalt sites of CuCo/SiO2 than of Co/SiO2. Thus, on CuCo/SiO2, CO is more likely to dissociate at the same sites where it linearly adsorbs, leading to increased probability of CO insertion and ethanol formation. A second type of site on Co/SiO2 is responsible for direct CO dissociation, leading to high activity and hydrocarbon selectivity on this catalyst, as well as faster deactivation.
Facile Preparation of Light Emitting Organic Metal Halide Crystals with Near-Unity Quantum Efficiency (2018)

We report the synthesis and characterization of (Ph4P)2SbCl5, a novel ionically bonded organic metal halide hybrid with a zero-dimensional (0D) structure at the molecular level. By cocrystallization of tetraphenylphosphonium (Ph4P+) and antimony (Sb3+) chloride salts, (Ph4P)2SbCl5 bulk single crystals can be prepared in high yield, which exhibit a highly efficient broadband red emission peaked at 648 nm with a photoluminescence quantum efficiency (PLQE) of around 87%. Density functional theory (DFT) calculations reveal the origin of emission as phosphorescence from the excitons localized at SbCl52– with strong excited-state structural distortion. Interestingly, (Ph4P)2SbCl5 bulk crystals with a PLQE of around 100% can be prepared via a rapid crystal growth process within minutes, followed by a spontaneous structural transformation. It was found that the rapid growth process yielded a yellow emitting kinetically favored metastable product containing solvent molecules, which turned into the red emitting thermodynamically stable product slowly at room temperature or quickly upon thermal treatment.
Effect of Soil Polluted with Crude Oil on Some Wood Properties of Casuarina equisetifolia (2016)

The current experiment was conducted to explore the effect of soil crude oil ( crude oil ) pollution on some wood properties of Casuarina equisetifolia. Four levels of pollution were applied on 40 (one-year) old seedlings . Measurements were taken by cutting the trees after two growth seasons from date of pollution .The studied Properties were fiber length, diameter, wall thickness, and specific gravity of external and internal wood. Results showed an adverse effect of pollution on fiber diameter more than on fiber length. While wall thickness did not affect. Fiber dimensions of external wood showed higher values than that of internal one, especially for fiber length. Specific gravity was affected by pollution and its interaction. A significant increase in specific gravity was observed with higher pollution levels for external wood only i.e. for the two layers formed after pollution.
Rotational Isomers of N-Methyl-N-arylacetamides and Their Derived Enolates: Implications for Asymmetric Hartwig Oxindole Cyclizations (2013)

The rotational preferences of N-(2-bromo-4,6-dimethylphenyl)-N-methyl 2-phenylpropanamide were studied as a model of precursors for Hartwig asymmetric oxindole cyclizations. The atropisomers of this compound were separated by flash chromatography, and then the enantiomers were resolved and the interconversions of the stereocenter and the N–Ar axis were studied. Under thermal conditions, the axis is very stable. Under the basic conditions of the Hartwig cyclization, both the stereocenter and the chiral axis equilibrate via enolate formation. The N–Ar rotation barrier of a 2-phenylacetamide analogue was reduced from 31 kcal mol–1 in the precursor to 17 kcal mol–1 in the enolate. Reasons for this dramatic barrier reduction and implications of both N–Ar and amide C–N rotations for Hartwig cyclizations are discussed.
Application of Measurement Models for Analysis of Impedance Spectra (1993)

Measurement models have been applied to electrochemical impedance data collected at the corrosion potential for a copper disk rotating in alkaline- and acid-aerated 0.5 M chloride solutions. Several applications of measurement models for the interpretation of experimental impedance data are demonstrated. Corrosion is a nonstationary process, and nonstationary behavior associated with corrosion frequently influences impedance data. If data can be shown to be consistent with the Kramers-Kronig relations, nonstationary influences can be neglected. Measurement models provide a quantitative method for identifying the portion of an impedance spectrum that is consistent with the Kramers-Kronig relations and, therefore, can be interpreted in terms of pseudo-steady-state models. Measurement models also provide a very sensitive means of interpreting impedance spectra in terms of the effects of physical parameters, such as immersion time and disk rotation speed.
Fast Beam Accumulation by Electron Cooling in the Heavy Ion Synchrotron SIS (1996)

An electron cooling system has been designed for the heavy ion synchrotron SIS. The purpose of this device is accumulation of weak injected beams of highly charged ions to the maximum intensity determined by the space charge limit. This is accomplished by repeated multiturn injection and simultaneous cooling at the injection energy. The cooling time has been estimated to be an order of magnitude shorter than the acceleration cycle time. Thus a corresponding increase of the average output intensity by about one order of magnitude is expected. The beam quality of the accumulated beams will also be improved.
Clear and Transparent Methyl Ester Sulphonate Micellar Systems for Mild Hair Shampoo Applications (2022)

"Methyl ester sulphonates (MES), which are produced from renewable vegetable oil-based materials and have an ISO 16128 natural origin index of 0.84, are promising new surfactants for conditioning hair shampoos. Previous studies have shown that MES has low skin irritation potential (i.e., mild to the skin), provides easier deposition of conditioning agents compared to sodium lauryl ether sulphate (SLES), and readily delivers desired rheology profiles. A drawback of MES is that it has poor solubility at low temperatures. The Krafft temperatures (TK) of MES-C16 and MES-C18 are 28 °C and 41 °C, respectively, which can be lowered substantially by using eutectic mixtures of MES-C16 and MES-C18; for example, MES-C16/C18 (3:1, w/w) has a TK of 15 °C. At temperatures below 15 °C, all mixtures of MES-C16 and MES-C18 are turbid due to the formation of MES crystals, and phase separation could occur during long-term storage. The solubility of MES could be further improved by incorporating the MES molecules into the micelles of other surfactants. In this study, the solubility of MES in pure water at 5 °C in the presence of alkyl polyglucosides (APG) was investigated. The results showed that the solubility of MES improved by &gt; 28 times in the presence of APG at low total surfactant concentrations and predicts that at higher total surfactant concentrations, solutions of MES and APG will remain transparent at 5 °C when the weight fraction of MES-C16, MES-C18, MES-C16/C18 (80:20), and MES-C16/C18 (60:40) are below 28 %, 15 %, 35 %, and 38 %, respectively. Predictions for MES-C16/C18 (80:20) and MES-C16/C18 (60:40) were verified using 25 % total surfactant concentration and storage at 5 °C for 12 weeks. MES/APG-based surfactant systems have promising potential in hair shampoo applications, because both surfactants have low skin irritation potentials and are produced from renewable raw materials."
Strong-field control of electron localisation during molecular dissociation (2008)

Abstract\n We demonstrate how the waveform of light can be used to control a molecular dissociation by steering and localization of electrons. Experimental results have been obtained for the dissociative ionization of the homonuclear and heteronuclear Hydrogen derivates D2 and HD. Asymmetric ejection of the ionic fragments reveals that light-driven electronic motion prior to dissociation localizes the electron on one of the two ions in the diatomic molecular ions in a controlled way. Extension of these results to electron transfer in complex molecules suggests a new paradigm for controlling photochemistry.
The Internet of Bodies: A Systematic Survey on Propagation Characterization and Channel Modeling (2021)

The Internet of Bodies (IoBs) is an imminent extension to the vast Internet of Things domain, where interconnected devices (e.g., worn, implanted, embedded, swallowed, etc.) are located in-on-and-around the human body form a network. Thus, the IoB can enable a myriad of services and applications for a wide range of sectors, including medicine, safety, security, wellness, entertainment, to name but a few. Especially, considering the recent health and economic crisis caused by the novel coronavirus pandemic, also known as COVID-19, the IoB can revolutionize today’s public health and safety infrastructure. Nonetheless, reaping the full benefit of IoB is still subject to addressing related risks, concerns, and challenges. Hence, this survey first outlines the IoB requirements and related communication and networking standards. Considering the lossy and heterogeneous dielectric properties of the human body, one of the major technical challenges is characterizing the behavior of the communication links in-on-and-around the human body. Therefore, this article presents a systematic survey of channel modeling issues for various link types of human body communication (HBC) channels below 100 MHz, the narrowband (NB) channels between 400 and 2.5 GHz, and ultrawideband (UWB) channels from 3 to 10 GHz. After explaining bio-electromagnetics attributes of the human body, physical, and numerical body phantoms are presented along with electromagnetic propagation tool models. Then, the first-order and the second-order channel statistics for NB and UWB channels are covered with a special emphasis on body posture, mobility, and antenna effects. For capacitively, galvanically, and magnetically coupled HBC channels, four different channel modeling methods (i.e., analytical, numerical, circuit, and empirical) are investigated, and electrode effects are discussed. Finally, interested readers are provided with open research challenges and potential future research directions.

α-Synuclein: Stable compact and extended monomeric structures and pH dependence of dimer formation (2004)

The protein alpha-synuclein, implicated in Parkinson's disease, was studied by combining nano-electrospray ionization (N-ESI) mass spectrometry and ion mobility. It was found that both the charge-state distribution in the mass spectra and the average protein shape deduced from ion mobility data, depend on the pH of the spray solution. Negative-ion N-ESI of pH 7 solutions yielded a broad charge-state distribution from -6 to -16, centered at -11, and ion mobility data consistent with extended protein structures. Data obtained for pH 2.5 solutions, on the other hand, showed a narrow charge-state distribution from -6 to -11, centered at -8, and ion mobilities in agreement with compact alpha-synuclein structures. The data indicated that there are two distinct families of structures: one consisting of relatively compact proteins with eight or less negative charges and one consisting of relatively extended structures with nine or more charges. The average cross section of a-synuclein at pH 2.5 is 33% smaller than for the extended protein sprayed from pH 7 solution. Significant dimer formation was observed when sprayed from pH 7 solution but no dimers were observed from the low pH solution. A plausible mechanism for aggregate formation in solution is proposed.
TDMA-based broadband fixed radio access: performance and implementation issues of adaptive equalizers (2002)

The performance of adaptive equalization strategies for future broadband fixed ATM radio access systems is investigated. The LMS and zero forcing algorithms are suitable for the downlink, whereas for the uplink, a fast converging RLS algorithm has to be employed. Furthermore, a hybrid F/TDMA has to be implemented to transmit the assumed 156 Mbit/s in the uplink. A complexity analysis comparing different RLS algorithms is given, showing that the QR-RLS algorithm is always a good option for the uplink of the application in mind.

Cu Plated I-Perl Cells: Ageing and Humidity Reliability Tests (2011)

In this work, a first reliability assessment of cells in which the standard Ag screen printed front side metallization is replaced by electroplated Cu, is made. The thermal stability of Ti/Cu plated cells is investigated in thermal ageing tests for a temperature range between 175 and 300oC. The time at which the threshold value of 5% cell efficiency degradation occurs, follows a linear relationship in the Arrhenius plot. This indicates a similar failure mechanism by thermal diffusion throughout this temperature range. The Cu cells are also used for preparing 1-cell modules in order to test their resistance to oxidation in 85/85 test conditions. First tests show a promising result of 4 out of 5 modules surviving 2000h of testing for unprotected Cu.
P-PW-05 Development of the non-resonance type ultra-sonic motor and its application for XY-stage (2003)

12-inch fine ceramic XY-stage driven by a NRUSM (non-resonance type ultrasonic motor), focused for LSI manufacturing devices, has achieved maximum velocity of 140 mm/s over the stroke of 300 mm, with 0.6 nm positioning accuracy. We report the results of the endurance test, 200km continuous driving, which was achieved by reciprocating the stage, under servo control operation.

Optical sensor employing a refractive index engineered metal oxide material (2023)

An optical sensor device includes an optical waveguide portion having a core, the core having a first refractive index, and a functional material layer coupled to the optical fiber portion, the functional material layer being made of a metal oxide material, the functional material layer being structured to have a second refractive index, the second refractive index being less than the first refractive index. The functional material layer may be a nanostructure material comprising the metal oxide material with a plurality of holes or voids formed therein such that the functional material layer is caused to have the second refractive index.
Additive Robotic Fabrication of Complex Timber Structures (2015)

The project described here, Additive Robotic Fabrication of Complex Timber Structures, investigates the potential and innovative methods for robot based assembly of complex wooden structures in the construction industry. Since 2012, in the framework of the National Research Programme "Resource Wood" (NRP 66)1, the ETH Zürich2 in cooperation with the Bern University of Applied Science3 has pursued the approach of industrially manufacturing non-standardized systems with digital fabrication. In that context material-specific and constructive aspects of wood assembly are combined in a continuous digital design and manufacturing process. In contrast to traditional approaches, for instance, mechanical processing of individual components and manual assembly, a robot based set-up as a further step in the pre-assembly is being investigated. This research approach is based on the assumption that efficient lightweight support structures can be manufactured from simple wood components of inferior quality or even from waste or left over materials. The first experiments with spatial wood assembly4 in connection with new types of adhesive and construction methods have been successfully carried out in several studies and with full scale prototypes.
