DHEA administration increases rapid eye movement sleep and EEG power in the sigma frequency range (1995)

Dehydroepi-androsterone (DHEA) exhibits various behavioral effects in mammals, at least one of which is enhancement of memory that appears to be mediated by an interaction with the gamma-aminobutyric acidA (GABAA) receptor complex. We investigated the effects of a single oral dose of DHEA (500 mg) on sleep stages, sleep stage-specific electroencephalogram (EEG) power spectra, and concurrent hormone secretion in 10 healthy young men. DHEA administration induced a significant (P < 0.05) increase in rapid eye movement (REM) sleep, whereas all other sleep variables remained unchanged compared with the placebo condition. Spectral analysis of five selected EEG bands revealed significantly (P < 0.05) enhanced EEG activity in the sigma frequency range during REM sleep in the first 2-h sleep period after DHEA administration. In contrast, the EEG power spectra of non-REM sleep were not affected, nor were the nocturnal time course curves of plasma cortisol, growth hormone, or testosterone concentration. The results suggest that DHEA administration has a mixed GABAA-agonistic/antagonistic effect, exerted either directly or through DHEA-induced changes in steroid metabolism. Because REM sleep has been implicated in memory storage, its augmentation in the present study suggests the potential clinical usefulness of DHEA in age-related dementia.
Broad-area semiconductor lasers with diffraction-grating mode control (1997)

Broad-area semiconductor lasers with stripe patterns formed on their front mirrors and the properties of such lasers are described. The stripes are of alternately different reflectivity and therefore the pat- tern acts as a low frequency grating. Such a grating significantly affects the shape of the laser output beam. The envelope of its intensity profile becomes almost Gaussian and the beam cross section is much closer to a circle than in the case of standard lasers. © 1997 Society of Photo-Optical Instrumentation Engineers.

重新审视《社区再投资法》的框架 (2009)

美国1977年颁布《社区再投资法》（Community Reinvestment Act，CRA）的原因，是因为发现存款类金融机构不能很好地满足整个社区的信贷需求。业界认为该法律可以通过多种途径改变银行在中低收入（LMI，low-and moderate-income）社区开展业务的方式。但在过去的数十年间，该法律本身以及相应法规已经发生了变化，
Generation of effector Vγ9Vδ2 T cells and evaluation of their response to phosphoantigen-loaded cells (2022)

Vγ9Vδ2 T cells are non-canonical T cells that use their T cell receptor to detect phosphoantigens bound to the internal domain of the HMBPP receptor (butyrophilin 3/2A1 complex). This protocol describes the expansion and purification of human effector Vγ9Vδ2 T cells from human buffy coat and describes how to assess their activation by antigen-containing target cells. While specifically focused on cytokine production, this protocol can be readily adapted to evaluate other effector functions of activated Vγ9Vδ2 T cells. For complete details on the use and execution of this protocol, please refer to Hsiao et al. (2022) and Hsiao and Wiemer (2018).
Hetero‐Multifunctional Poly(ethylene glycol) Copolymers with Multiple Hydroxyl Groups and a Single Terminal Functionality (2009)

Hetero-multifunctional poly(ethylene glycol-co-glycerol) random copolymers with multiple hydroxyl functionalities and a single terminal functionality have been prepared by copolymerization of ethylene oxide (EO) and ethoxy ethyl glycidyl ether (EEGE) with the use of a suitable initiator, introducing a protected amino group or a double bond, respectively. Acidic deprotection was used for removal of the acetal protecting groups in the chain, and the terminal amino group was regenerated by catalytic hydrogenation. A series of copolymers with narrow polydispersity was obtained, varying comonomer fractions from 3 to 67% and molecular weights in the range of 5 000-32 000 g · mol(-1) (1.05 < $\overline M _{\rm w} /\overline M _{\rm n}$ < 1.25). Molecular and thermal characterization was carried out using (1) H- and (13) C NMR, SEC and differential scanning calorimetry (DSC).
Action of newly developed tetrazolato-bridged dinuclear platinum(II) complexe as the candidate of effective antitumor drug on the structure of large DNA (2016)

We report the action of tetrazolato-bridged dinuclear platinum(II) complex, 5-H-Y (2+), and SPD (3+) on the higher-order and secondary structure of DNA through the observations with fluorescence microscopy and CD measurements. From the measurement on the higher-order structure of a giant DNA in solution with fluorescence microscopy, it was found that 5-H-Y (2+) causes shrinking of DNA above 10 μM. On the contrary, SPD (3+) showed negligible change on the higher-order structure of DNA up to 30 μM. From circular dichroism (CD) measurements, it becomes clear that 5-H-Y (2+) induces the transition of the secondary structure of DNA from B-form to C-form.
Taking a Closer Look: Clinical and Histopathological Characteristics of Culture-Positive versus Culture-Negative Pulmonary Mucormycosis (2022)

Cultural recovery of Mucorales from hyphae-laden tissue is poor, and the clinical implications of culture positivity are scarcely studied. Therefore, we compared clinical and histological characteristics of culture-positive and culture-negative histology-proven pulmonary mucormycosis cases among cancer patients. Histology specimens were blindly reviewed by a Thoracic Pathologist and graded on four histopathologic features: hyphal quantity, tissue necrosis, tissue invasion, and vascular invasion. Twenty cases with a corresponding fungal culture were identified; five were culture-positive, and 15 culture-negative. Although no statistically significant differences were found, culture-positive patients were more likely to exhibit a high burden of necrosis and have a high burden of hyphae but tended to have less vascular invasion than culture-negative patients. In terms of clinical characteristics, culture-positive patients were more likely to have acute myeloid leukemia (60% vs. 27%, p=0.19), a history of hematopoietic cell transplant (80% vs. 53%, p=0.31), severe lymphopenia (absolute lymphocyte count &amp;le;500/&amp;micro;L, 100% vs. 73%, p=0.36), and monocytopenia (absolute monocyte count &amp;le;100/&amp;micro;L, 60% vs. 20%, p=0.11). Forty-two-day all-cause mortality was comparable between culture-positive and culture-negative patients (60% and 53%, p=0.80). This pilot study represents the first comprehensive histopathological scoring method to examine the relationship between histopathologic features, culture positivity, and clinical features of pulmonary mucormycosis.
Fabrication of nanocomposite using self-forming core/shell nanoparticles and its magnetic properties at up to gigahertz bands for high-frequency applications (2009)

A nanocomposite with a magnetic loss factor (tan δ=μ″/μ′) of less than 1% at up to 1 GHz was synthesized using self-forming core/shell nanoparticles of metal/oxide; these were concentrated to achieve a relative permeability (μ′) of more than three. The self-forming core/shell nanoparticles were synthesized by oxidation of a portion of FeCoAl nanoparticles in thermal plasma. An FeCoAl complex oxide shell of approximately 2 nm in thickness was formed on the surface of FeCo nanoparticle, which had approximately 20 nm in diameter. The core/shell nanoparticles were mixed with resin to form bulk material of millimeter-order thickness.
Video Exposure Monitoring—A Means of Studying Sources of Occupational Air Contaminant Exposure, Part I—Video Exposure Monitoring Techniques (1993)

Abstract Conventional sampling with pumps and sampling media can be used to determine whether exposures to air contaminants are excessive. Unfortunately, such results provide few insights into the reasons for the excessive exposures. However, Video Exposure Monitoring can be used to identify the sources causing these excessive exposures. Any movable instrument that has an analog or digital output can potentially be used for Video Exposure Monitoring. The instrument should be light enough to mount on a worker, be specific for the chemical interest, and have a short time constant. Although most existing direct-reading instruments do not simultaneously meet all these requirements, currently available instruments, such as aerosol photometers, photoionization detectors, and portable infrared analyzers have been used effectively. The analog or digital output from direct-reading instruments can be recorded by data-logging devices. The data-logging devices transfer the exposure data to a personal computer for storage and statistical analysis. In addition to statistical analysis of the data, the personal computer, outfitted with a video overlay system, can also be used to overlay the exposure data onto a video recording of worker activities. The worker's exposure is displayed as a moving bar proportional in height to the air contaminant concentration. The work activity video image with the overlaid exposure data can be recorded on a second video tape. By replaying the overlaid video recording, this technique shows how worker exposures are related to work activities, permitting industrial hygienists to make recommendations for control measures focusing on actual exposure sources. Furthermore, these video recordings can be used to train workers to avoid work practices that cause elevated air contaminant exposures.

SOLE: context‐aware sharing of living experiences (2011)

Purpose The rapid advances in the technologies of mobile computing and wireless communications have facilitated the use of applications and services on handheld devices. Sharing of living experience (SOLE) is one such service, through which users can share their experience of daily activities such as shopping, entertainment, and traveling. This paper seeks to study SOLE in more detail. Design/methodology/approach The paper presents an application framework for a context‐aware SOLE which considers location, preferences, and other useful information for a seamless user experience. SOLE leverages on the service‐oriented middleware, Coalition. Entities of interest are represented as services registered with Coalition, which are organized using location information. This facilitates location‐based selection of entities for associating or retrieving experiences. In addition, Coalition incorporates the contexts of users in the discovery and delivery of experience information. Besides, to cater for resource constraints of mobile devices, the concept of “proxy” is introduced. Findings A detailed study of SOLE, namely, its design as well as its interaction with the middleware, information providers and information consumers, is provided. As a proof of concept, a prototype of SOLE for mobile phone users is also provided. The experiments show the ease of using SOLE and its acceptable performance in practice. Originality/value SOLE is generic and scalable, by not assuming a specific application scenario; flexible, by allowing the user to choose where to store the experience data and to specify his audience; and context‐aware by considering the contexts of the user such as location and preferences in the experience sharing process.
Boron, nitrogen and phosphorous substitutionally doped single‐wall carbon nanotubes studied by resonance Raman spectroscopy (2009)

Abstract Substitutional doping on single‐wall an on multi‐wall carbon nanotubes is possible by adding new atoms during the growing process. In this work we analyze the changes in the Raman spectra of SWNT samples substitutionaly doped with boron, nitrogen, and phosphorous. We find that small amounts of dopants are not enough to change the frequency of the tangential G mode, but there is a doping‐dependent shift in ω G when the P‐doped SWNTs are measured at high laser power, indicating that doping can change the thermal properties of SWNT bundles. This result seems to hold also for B‐doped samples, but not for N‐doped SWNTs, showing a different behavior for donors (P‐ and N‐ doping). The I D / I G ratio analysis to provide information about the doping level in the SWNT samples is also discussed.
Network-aware migration control and scheduling of differentiated virtual machine workloads (2009)

Server virtualization enables dynamic workload management for data centers. However, especially live migrations of virtual machines (VM) induce significant overheads on physical hosts and the shared network infrastructure possibly leading to host overloads and SLA violations of co-hosted applications. While some recent work addresses the impact of live migrations on CPUs of physical hosts, little attention has been given to the control and optimization of migration algorithms and migration-related network bandwidth consumption. In this paper we introduce network topology aware scheduling models for VM live migrations. We propose a scheme for classifying VMs based on their workload characteristics and propose adequate resource and migration scheduling models for each class, taking network bandwidth requirements of migrations and network topologies into account. We also underline the necessity for additional migration control parameters for efficient migration scheduling.
Screening and treatment of asymptomatic bacteriuria of pregnancy to prevent pyelonephritis: A cost-effectiveness and cost-benefit analysis (1995)

When compared with a policy of no screening, screening for and treatment of asymptomatic bacteriuria to prevent pyelonephritis in pregnancy is cost-beneficial whether based on the leukocyte esterase-nitrite dipstick or on urine culture. However, the culture strategy is not cost-beneficial when compared with the dipstick strategy.
24/7 workflow for bloodstream infection diagnostics in microbiology laboratories: the first step to improve clinical management (2022)

Abstract Objectives We aimed to evaluate the impact of an uninterrupted workflow regarding blood cultures on turnaround time and antibiotic prescription. Methods Monomicrobial episodes of bacteremia were retrospectively evaluated before and after a continuous 24/7 workflow was implemented in our clinical microbiology laboratory (pre- and post-intervention periods; PREIP and POSTIP). Primary outcome was the time from specimen collection to the first change in antibiotic therapy. Secondary outcomes included the time from specimen collection to effective antibiotic therapy and to antibiotic susceptibility testing results (or turnaround time), as well as hospital length of stay and all-cause mortality at 30 days. Results A total of 548 episodes of bacteremia were included in the final analysis. There was no difference in PREIP and POSTIP regarding patient characteristics and causative bacteria. In POSTIP, the mean time to the first change in antibiotic therapy was reduced by 10.4 h (p&lt;0.001). The time to effective antibiotic therapy and the turnaround time were respectively reduced by 4.8 h (p&lt;0.001) and 5.1 h (p=0.006) in POSTIP. There was no difference in mean hospital length of stay or mortality between the two groups. Conclusions Around the clock processing of blood cultures allows for a reduction in turnaround time, which in turn reduces the delay until effective antibiotic therapy prescription.
Minimally invasive transforaminal lumbar interbody fusion: indications, technique, and complications (2006)

The authors provide an overview of the minimally invasive transforaminal lumbar interbody fusion (TLIF) procedure including indications, technique, and complications. This novel technique is a method of achieving circumferential lumbar fusion using a unilateral dorsal approach. Minimally invasive TLIF uses a tubular retractor that is inserted via a muscle-dilating exposure, thereby minimizing the approach-related morbidity. This procedure is ideal for refractory mechanical low-back and radicular pain associated with spondylolisthesis, degenerative disc disease, and recurrent disc herniation. The authors' clinical experience and review of the medical literature indicate that TLIF can be effectively and safely performed in a minimally invasive fashion.
Multi-path correction model for multi-channel airborne SAR (2009)

This paper analyzes the multi-path component effect in the airborne SAR context, proposing a model as an approach to correct the generated disturbances in the processed phase and amplitude images. The method assumes along-track interferometric or polarimetric data to estimate the unknowns of the model. Airborne data acquired by the F-SAR system of DLR are used to evaluate the performance of the proposed approach.
P‐82: Synthesis and Characterization of (R 0.96 Eu 0.02 Dy 0.02 ) 2 MgSi 2 O 7 (R=Ca, Sr) Phosphors (2007)

Abstract Rare earth ions doped alkaline earth silicate phosphors were prepared by the conventional ceramic processing route under various conditions. The Rietveld refinement of the crystal structure of Ca 2 MgSi 2 O 7 and Sr 2 MgSi 2 O 7 compositions indicated that a single phase of akermanite was well synthesized. (R 0.96 Eu 0.02 Dy 0.02 ) 2 MgSi 2 O 7 (R=Ca, Sr) phosphors showed fairly good optical properties under the processing conditions of non‐additive flux, 1000 °C calcination temperature, and 2mol% activators. (Sr 0.96 Eu 0.02 Dy 0.02 ) 2 MgSi 2 O 7 and (Ca 0.96 Eu 0.02 Dy 0.02 ) 2 MgSi 2 O 7 phosphors emitted 465 nm and 530 nm lights, respectively, by 325 nm exciting sources. Increase of Ca/Sr ratio of (Ca, Sr)‐akermanite phosphor caused the shift of optic‐center from blue to green region throughout the composition range of isostructural Sr‐ and Ca‐akermanites. And median diameters of powdered phosphors were about 3–4 μm.
A k-Nearest-Neighbour Classifier for Assessing Consumer Credit Risk (1996)

SUMMARY The last 30 years have seen the development of credit scoring techniques for assessing the creditworthiness of consumer loan applicants. Traditional credit scoring methodology has involved the use of techniques such as discriminant analysis, linear or logistic regression, linear programming and decision trees. In this paper we look at the application of the k-nearest-neighbour (k-NN) method, a standard technique in pattern recognition and nonparametric statistics, to the credit scoring problem. We propose an adjusted version of the Euclidean distance metric which attempts to incorporate knowledge of class separation contained in the data. Our k-NN methodology is applied to a real data set and we discuss the selection of optimal values of the parameters k and D included in the method. To assess the potential of the method we make comparisons with linear and logistic regression and decision trees and graphs. We end by discussing a practical implementation of the proposed k-NN classifier.

Disease Suppressive Soils: New Insights from the Soil Microbiome (2017)

Soils suppressive to soilborne pathogens have been identified worldwide for almost 60 years and attributed mainly to suppressive or antagonistic microorganisms. Rather than identifying, testing and applying potential biocontrol agents in an inundative fashion, research into suppressive soils has attempted to understand how indigenous microbiomes can reduce disease, even in the presence of the pathogen, susceptible host, and favorable environment. Recent advances in next-generation sequencing of microbiomes have provided new tools to reexamine and further characterize the nature of these soils. Two general types of suppression have been described: specific and general suppression, and theories have been developed around these two models. In this review, we will present three examples of currently-studied model systems with features representative of specific and general suppressiveness: suppression to take-all (Gaeumannomyces graminis var. tritici), Rhizoctonia bare patch of wheat (Rhizoctonia solani AG-8), and Streptomyces. To compare and contrast the two models of general versus specific suppression, we propose a number of hypotheses about the nature and ecology of microbial populations and communities of suppressive soils. We outline the potential and limitations of new molecular techniques that can provide novel ways of testing these hypotheses. Finally, we consider how this greater understanding of the phytobiome can facilitate sustainable disease management in agriculture by harnessing the potential of indigenous soil microbes.

Reconfigurable Intelligent Surfaces for Future Wireless Networks: A Channel Modeling Perspective (2021)

While researchers have set their sights on future wireless networks of 2030, communications through reconfigurable intelligent surfaces (RISs) appears as one of the potential enabling technologies for 6G wireless networking. This article aims to shed light on the potential use-cases of RISs in future wireless systems by means of a novel channel modeling methodology as well as a new software tool for RIS-empowered millimeter-wave communication systems. It is shown by the open-source, user-friendly, and widely applicable SimRIS Channel Simulator, whose 2.0 version is proposed and goes online by this article, that RISs will work under certain use-cases and communication environments. Potential future research directions are also discussed to bridge the gap between the theory and practice of RIS-empowered systems toward their standardization for 6G wireless networks.
