Thirty days complication rate following surgery performed for deep‐brain‐stimulation (2007)

Serious adverse events (SAEs) during the first 30 postoperative days after stereotactic surgery for Deep-Brain-Stimulation performed in 1,183 patients were retrospectively collected from five German stereotactic centers. The mortality rate was 0.4% and causes for death were pneumonia, pulmonary embolism, hepatopathy, and a case of complicated multiple sclerosis. The permanent surgical morbidity rate was 1%. The most frequently observed SAEs were intracranial hemorrhage (2.2%) and pneumonia (0.6%). Skin infection occurred in 5 of 1,183 patients (0.4%). Surgical complications caused secondary AEs (e.g. pneumonia) preferentially in older patients and in patients treated for Parkinson's disease (PD). Complication rates did not differ among the five centers.
Actinium-225 in Targeted Alpha-Particle Therapeutic Applications (2011)

Alpha particle-emitting isotopes are being investigated in radioimmunotherapeutic applications because of their unparalleled cytotoxicity when targeted to cancer and their relative lack of toxicity towards untargeted normal tissue. Actinium- 225 has been developed into potent targeting drug constructs and is in clinical use against acute myelogenous leukemia. The key properties of the alpha particles generated by 225Ac are the following: i) limited range in tissue of a few cell diameters; ii) high linear energy transfer leading to dense radiation damage along each alpha track; iii) a 10 day halflife; and iv) four net alpha particles emitted per decay. Targeting 225Ac-drug constructs have potential in the treatment of cancer.
AGRUPAMENTO DE CAFÉS CONILON ESPECIAIS POR CONDUTIVIDADE ELÉTRICA (2017)

Métodos apropriados para a avaliação da qualidade sensorial do café conilon foram desenvolvidos recentemente e exigem provadores experientes e especializados. A análise da condutividade elétrica de exsudados dos grãos de café é um método auxiliar para determinação da qualidade do café, baseado no fato de a condutividade elétrica ser maior em grãos de café de menor qualidade por estes possuírem membranas menos íntegras, que lixiviam maior conteúdo de íons e solutos. Neste trabalho objetivou-se avaliar a capacidade de se discriminar cafés conilon especiais de cafés comerciais através da análise da condutividade elétrica dos grãos. Foram avaliadas 10 amostras de café conilon, cinco de cafés especiais e cinco de cafés comerciais. A análise de condutividade elétrica foi um método eficiente para discriminar os cafés especiais dos cafés comerciais, agrupando-os em dois grupos distintos pelo método UPGMA. Os valores de condutividade são maiores em cafés de menor qualidade, com grãos menores e maior percentagem de defeitos.
Addressing cold-start problem in recommendation systems (2008)

Recommender systems for automatically suggested items of interest to users have become increasingly essential in fields where mass personalization is highly valued. The popular core techniques of such systems are collaborative filtering, content-based filtering and combinations of these. In this paper, we discuss hybrid approaches, using collaborative and also content data to address cold-start - that is, giving recommendations to novel users who have no preference on any items, or recommending items that no user of the community has seen yet. While there have been lots of studies on solving the item-side problems, solution for user-side problems has not been seen public. So we develop a hybrid model based on the analysis of two probabilistic aspect models using pure collaborative filtering to combine with users' information. The experiments with MovieLen data indicate substantial and consistent improvements of this model in overcoming the cold-start user-side problem.
Turning a native or corroded Mg alloy surface into an anti-corrosion coating in excited CO2 (2018)

Despite their energy-efficient merits as promising light-weight structural materials, magnesium (Mg) based alloys suffer from inadequate corrosion resistance. One primary reason is that the native surface film on Mg formed in air mainly consists of Mg(OH)<sub>2</sub> and MgO, which is porous and unprotective, especially in humid environments. Here, we demonstrate an environmentally benign method to grow a protective film on the surface of Mg/Mg alloy samples at room temperature, via a direct reaction of already-existing surface film with excited CO<sub>2.</sub> Moreover, for samples that have been corroded obviously on surface, the corrosion products can be converted directly to create a new protective surface. Mechanical tests show that compared with untreated samples, the protective layer can elevate the yield stress, suppress plastic instability and prolong compressive strains without peeling off from the metal surface. This environmentally friendly surface treatment method is promising to protect Mg alloys, including those already-corroded on the surface.

Dementia with Lewy bodies may present as dementia and REM sleep behavior disorder without parkinsonism or hallucinations (2002)

Rapid eye movement (REM) sleep behavior disorder (RBD) is a sleep disturbance that commonly occurs in Dementia with Lewy bodies (DLB). Retrospective examination of DLB course has shown that RBD and cognitive decline may precede the onset of parkinsonism and visual hallucinations. Therefore, some patients with DLB may initially present with dementia and RBD, but would not meet current formal criteria for probable DLB at that time. The purpose of this study is to determine whether patients with dementia and RBD, who do not have parkinsonism or visual hallucinations, have cognitive profiles that can be distinguished from autopsy-confirmed definite AD, but not from clinically probable DLB. If so, this would support the hypothesis that the presence of RBD and dementia, as the only presenting symptoms, reflects the early manifestation of DLB. Results show that early dementia in probable DLB and dementia with RBD are neuropsychologically indistinguishable. Both groups differ from definite AD of a similar early stage with significantly worse visual perceptual organization, sequencing and letter fluency but significantly better confrontation naming and verbal memory. In addition, follow-up data from a subset of patients with dementia and RBD reveal the subsequent development of parkinsonism or hallucinations 1 to 6 years later. Results indicate that the presentation of dementia and RBD is suggestive of underlying Lewy body disease and not Alzheimer's disease. This provides further evidence in support of including RBD as one of the core diagnostic features of DLB.

Miniature Fourier transform spectrometer based on wavelength dependence of half-wave voltage of a LiNbO_3 waveguide interferometer (2014)

A simple and reliable spectrum-retrieval method was proposed for the development of miniature stationary Fourier transform (FT) spectrometers based on a LiNbO₃ (LN) waveguide Mach-Zehnder interferometer (MZI) modulator. The method takes into account the wavelength dependence of the optical pathlength difference (OPD) and allows us to use a nonlinear voltage ramp to modulate the OPD. The method is based on the dispersion of the half-wave voltage, which was measured to be a monotonous polynomial function of the wavelength for the LN waveguide MZI used. With the measured dispersion of the half-wave voltage, the OPD, as a linear function of the modulating voltage, can be accurately determined at each wavelength in the near-infrared region in which the MZI used is a single-mode device. A prototype FT spectrometer was prepared using a LN waveguide MZI modulator based on the above method. The experimental results demonstrated that the spectrometer can be used for accurate determination of the laser wavelength and for liquid absorptiometry.
Accuracy of Tablet Splitting (1998)

We attempted to determine the accuracy of manually splitting hydrochlorothiazide tablets. Ninety-four healthy volunteers each split ten 25-mg hydrochlorothiazide tablets, which were then weighed using an analytical balance. Demographics, grip and pinch strength, digit circumference, and tablet-splitting experience were documented. Subjects were also surveyed regarding their willingness to pay a premium for commercially available, lower-dose tablets. Of 1752 manually split tablet portions, 41.3% deviated from ideal weight by more than 10% and 12.4% deviated by more than 20%. Gender, age, education, and tablet-splitting experience were not predictive of variability. Most subjects (96.8%) stated a preference for commercially produced, lower-dose tablets, and 77.2% were willing to pay more for them. For drugs with steep dose-response curves or narrow therapeutic windows, the differences we recorded could be clinically relevant.
A Case of Seborrheic Keratosis Showing Zosteriform Distribution (2004)

Seborrheic keratosis is a common skin disease in the elderly, and when multiple lesions are present, scattered distribution is the rule. Here we present a case of seborrheic keratosis showing zosteriform distribution. The patient was a 41-year-old female whom since childhood presented multiple brownish or black colored papules on her right back. The papules were linearly grouped, thereby showing zosteriform distribution. The histopathologic findings revealed a typical acanthotic type of seborrheic keratosis. As we know, this type of distribution in seborrheic keratosis has not been reported so far.
The Operational Airline Crew Scheduling Problem (1998)

This paper describes the operational airline crew scheduling problem and represents a first published attempt to solve it. The problem consists of modifying, as necessary, personalized planned monthly assignments of airline crew members during day-to-day operations. It requires covering, at minimal cost, all flight segments from a given time period with available crew while minimizing the disturbances of crew members. To generate modified pairings for selected crew members, both the classical crew pairing problem and the problem of constructing personalized monthly assignments must be treated simultaneously. An optimization approach is proposed for the problem in which the flight schedule is fixed and represents input data. The problem is mathematically formulated as a Set Partitioning type problem, and a column generation method embedded in a branch-and-bound search tree has been implemented to solve it. Good results, from the point of view of both solution times and achieved objectives, have been obtained on generated test problems. Because the solution time is reasonable, several different scenarios of the same problem may be solved. A final decision can then be made by considering all scenarios and choosing the one whose solution is the best in the given situation.
Current and Future Bots in Software Development (2019)

Bots that support software development ("DevBots") are seen as a promising approach to deal with the ever-increasing complexity of modern software engineering and development. Existing DevBots are already able to relieve developers from routine tasks such as building project images or keeping dependencies up-to-date. However, advances in machine learning and artificial intelligence hold the promise of future, significantly more advanced, DevBots. In this paper, we introduce the terminology of contemporary and ideal DevBots. Contemporary DevBots represent the current state of practice, which we characterise using a facet-based taxonomy. We exemplify this taxonomy using 11 existing, industrial-strength bots. We further provide a vision and definition of future (ideal) DevBots, which are not only autonomous, but also adaptive, as well as technically and socially competent. These properties may allow ideal DevBots to act more akin to artificial team mates than simple development tools.
Layer-by-Layer Growth of GaN on GaAs Substrates by Alternate Supply of GaCl<sub>3</sub> and NH<sub>3</sub> (1996)

Atomic layer epitaxy (ALE) of GaN on GaAs substrates was tried by alternate supply of GaCl 3 and NH 3 , and the growth process was analyzed by the surface photo-absorption (SPA) method. When the GaN layers were grown on GaAs surface at 500° C, typical SPA signals indicating the layer-by-layer growths were observed. Change in the reflection intensity (SPA signal) after the GaCl 3 supply for the GaN growth was much slower than that of GaAs. This result indicates that the reaction between GaCl 3 and N or NH 3 was much slower than that between GaCl 3 and As or AsH 3 . The crystallinity of GaN grown on (001) GaAs was almost amorphous. On the other hand, the GaN grown on (111) GaAs had a wurtzite structure and was a single crystal.
Oridonin effectively reverses the drug resistance of cisplatin involving induction of cell apoptosis and inhibition of MMP expression in human acute myeloid leukemia cells (2017)

Cisplatin is the first generation platinum-based chemotherapy agent. However, the extensive application of cisplatin inevitably causes drug resistance, which is a major obstacle to cancer chemotherapy. Oridonin is a diterpenoid isolated from <i>Rabdosia rubescens</i> with potent anticancer activity. The aim of our study is to investigate the role of oridonin to reverse the cisplatin-resistance in human acute myeloid leukemia (AML) cells. The effect of oridonin on human AML cell proliferation was evaluated by MTT assay, cell migration and invasion were evaluated by transwell migration and invasion assays in cisplatin-resistant human AML cells. Furthermore, cell apoptosis was examined by flow cytometry. The inhibitive effect of oridonin <i>in vivo</i> was determined using xenografted nude mice. In addition, the expressions of MMP2 and MMP9 were detected by Western blot. There was a synergistic antitumor effect between cisplatin and oridonin on cisplatin-resistant human AML cells <i>in vitro</i> and <i>in vivo</i>. In addition, the combination of cisplatin and oridonin synergistically induced cell apoptosis. Furthermore, the combination treatment not only inhibited AML cell migration and invasion, but more significantly, decreased the expressions of MMP2 and MMP9 proteins. Our results suggest that the synergistic effect between both agents is likely to be driven by the inhibition of MMP expression and the resulting increased apoptosis.
Principles and Parameters: An Introduction to Syntactic Theory (1997)

Principles and Parameters is a new textbook intended for the advanced undergraduate or postgraduate student of linguistics. In this readable and authoritative survey of the theory, incorporating much of Government and Binding (GB) theory, Peter Culicover summarizes the major proposals and results of Case theory, Theta theory, X'-theory, Binding theory, the theory of A- and A'- movement, locality conditions, and the theory of Logical Form (LF). He provides an up-to-date introduction to a number of more recent proposals, including Chomsky's Minimalist Program, Larsonian shells, and Kayne's Antisymmetry theory. A major concern and organizing principle of the book is to give the student an understanding of how specific methodological assumptions underlie the core analyses that have played a central role in the development of the theory. Each chapter is followed by an extensive set of exercises which lead the student from the point of applying the mechanics of the theory to developing and organizing new data, providing analyses, and exploring alternative hypotheses. There are also graded and annotated guides to further reading for each chapter, and, as a general aid to the student, a comprehensive glossary of terms. This book is intended for courses: Advanced Syntax; Government and Binding Theory; Principles and Parameters Theory Level: Final year undergraduate; postgraduate, supplementary for some second year undergraduate courses.
Correction of a Glutathione Deficiency in the Aging Mosquito Increases Its Longevity (1987)

The decrease of tissue glutathione (GSH) concentrations in different senescent organisms gave rise to our hypothesis that a glutathione deficiency is a biochemical cause of the aging process. A rigorous test of this notion would be the correction of the deficiency and concomitant increase in life span. To this end, adult mosquitoes were fed magnesium thiazolidine-4-carboxylic acid, and their GSH levels and life spans were determined. The GSH levels increased 50-100% (P less than 0.005) regardless of the age when feeding was initiated or whether the feeding period extended over 2 days or the entire life span. Also the median life spans increased 30-38% over control values (P less than 0.005). The responses were specific for the thiazolidine carboxylate moiety, because MgCl2 had no effect. These findings confirm the GSH deficiency hypothesis and demonstrate a specific biochemical mechanism of aging that can be nutritionally modified.
Intelligent video surveillance for monitoring fall detection of elderly in home environments (2008)

Video surveillance is an omnipresent topic when it comes to enhancing security and safety in the intelligent home environments. In this paper, we propose a novel method to detect various posture-based events in a typical elderly monitoring application in a home surveillance scenario. These events include normal daily life activities, abnormal behaviors and unusual events. Due to the fact that falling and its physical-psychological consequences in the elderly are a major health hazard, we monitor human activities with a particular interest to the problem of fall detection. Combination of best-fit approximated ellipse around the human body, projection histograms of the segmented silhouette and temporal changes of head position, would provide a useful cue for detection of different behaviors. Extracted feature vectors are fed to a MLP neural network for precise classification of motions and determination of fall event. Reliable recognition rate of experimental results underlines satisfactory performance of our system.
Active key frame selection for 3D model reconstruction from crowdsourced geo-tagged videos (2014)

Automatic reconstruction of 3D models is attracting increasing attention in the multimedia community. Scene recovery from video sequences requires a selection of representative video frames. Most prior work adopted content-based techniques to automate key frame extraction. However, these methods take no frame geo-information into consideration and are still compute-intensive. Here we propose a new approach for key frame selection based on the geographic properties of videos. Currently, an increasing number of user-generated videos (UGVs) are collected — a trend that is driven by the ubiquitous availability of smartphones. Additionally, it has become easy to continuously acquire and fuse various sensor data (e.g., geo-spatial metadata) with video to create geo-tagged mobile videos. Our novel technique utilizes these underlying geo-metadata to select the most representative frames. Specifically, a key frame subset with minimal spatial coverage gain difference is extracted by incorporating a manifold structure into reproducing a kernel Hilbert space to analyze the spatial relationship among the frames. Our experimental results illustrate that the execution time of the 3D reconstruction is shortened while the model quality is preserved.
Tooth remineralization using bio-active glass - A novel approach (2011)

Teeth go through a natural, continuous process of demineralization and re-mineralization. Demineralization occurs due to bacterial acids, foods and physiological process. Mineralization occurs from the calcium and phosphorus (normally present in saliva) precipitating into a crystalline form of calcium phosphate called Hydroxy Carbonate Apatite (HCA), which is the mineral component of all teeth and bones. Since natural re-mineralization is inadequate to maintain strong enamel, the natural re-mineralization process needs to be augmented. The discovery of Bioactive Glass pushed the boundaries of biomaterials capability and their function. In an era of bio-inert materials and implantation, Hench determined the critical steps for bioactive glass-ceramic interaction with the human body in order to bond. Various dentifrices have been formulated that have calcium-sodium-phosphosilicate as their prime constituent, which enhance tooth re-mineralization by providing calcium and phosphorus to the tooth surface. This paper is an attempt to highlight the unique re-mineralizing properties of Bio active glass.
Screen Content Coding Based on HEVC Framework (2014)

Screen content like cartoons, captures of typical computer screens or video with text overlay or news ticker is an important category of video, which needs new techniques beyond the existing video coding techniques. In this paper, we analyze the characteristics of screen content and coding efficiency of HEVC on screen content. We propose a new coding scheme, which adopts a non-transform representation, separating screen content into color component and structure component. Based on the proposed representation, two coding modes are designed for screen content to exploit the directional correlation and non-translational changes in screen video sequences. The proposed scheme is then seamlessly incorporated into the HEVC structure and implemented into HEVC range extension reference software HM9.0. Experimental results show that the proposed scheme achieves up to 52.6% bitrate saving compared with HM9.0. On average, 35.1%, 29.2% and 23.6% bitrate saving are achieved with intra, random-access and low-delay configurations, respectively. The visual quality of the decoded video sequences is also significantly improved by reducing ringing artifacts around sharp edges and reserving the shape of text without blur.
Effect of Storage Conditions on The Weight and Appearance of Dried Blood Spot Samples on Various Cellulose-Based Substrates (2010)

Blood spots are dry within 90 min of spotting. However, the substrates examined behave differently when exposed to conditions of high relative humidity and temperature, in some cases resulting in the integrity of the substrate and DBS sample being compromised. It is recommended that these factors be investigated as part of method development and validation.
Generation of microfluidic flow using an optically assembled and magnetically driven microrotor (2014)

The key components in microfluidic systems are micropumps, valves and mixers. Depending on the chosen technology, the realization of these microsystems often requires rotational and translational control of subcomponents. The manufacturing of such active components as well as the driving principle are still challenging tasks. A promising all-optical approach could be the combination of laser direct writing and actuation based on optical forces. However, when higher actuation velocities are required, optical driving might be too slow. Hence, a novel approach based on optical assembling of microfluidic structures and subsequent magnetic actuation is proposed. By applying the optical assembly of microspherical building blocks as the manufacturing method and magnetic actuation, a microrotor was successfully fabricated and tested within a microfluidic channel. The resulting fluid flow was characterized by introducing an optically levitated measuring probe particle. Finally, a freely moving tracer particle visualizes the generated flow. The tracer particle analysis shows average velocities of 0.4–0.5 µm s−1 achieved with the presented technology.
