Biological and Magnetic Contrast Evaluation of Shape-Selective Mn–Fe Nanowires (2009)

One-dimensional composite Mn-Fe oxide nanostructures of different sizes (nanoneedles, nanorods, and nanowires) were prepared by a linker-induced organization of manganese-doped iron oxide nanoparticles. The nanostructures were obtained by the treatment of MnFe(2)O(4) nanoparticles in the presence of cystamine. The average lengths of nanoneedle, nanorod, and nanowire are approximately 400, 800, and 1000 nm, respectively. High-resolution transmission electron microscopy (HR-TEM), energy-dispersive X-ray (EDX) spectroscopy, and inductively coupled plasma-optical emission spectroscopy (ICP-OES) were employed to characterize the morphologies and the elemental contents of the nanostructures. As an example of their potential applications, these nanostructures were explored as the cell-labeling agents for magnetic resonance imaging (MRI). The magnetic contrast properties of the nanostructures were characterized by a 1.5 T (Tesla) whole body MR system. 10 microg/mL of the nanostructures caused substantial negative contrast. After in vitro incubation, the nanostructures could be effectively incorporated into the cells of a monocyte/macrophage cell line (RAW264.7). These cells' viability and proliferation potential were not affected when the labeling concentration was less than 50 microg/mL.
An ontology-based context management and reasoning process for UbiComp applications (2005)

UbiComp applications operate within an extremely dynamic and heterogeneous environment and have to dynamically adapt to changes in their environment as a result of users' or other actors' activities. So context definition, representation, management and use become important factors that affect their operation. To ease the development of such applications it is necessary to decouple application composition from context acquisition and representation, and at the same time provide universal models and mechanisms to manage context. In this paper is presented an approach for building a context-aware UbiComp system organised in hierarchical levels. The focus of the paper is on an ontology-based context modelling, management and reasoning process developed for composing context-aware UbiComp applications from AmI artefacts.
Investigation and Suppression of the Gate Disturb Effect in Source-Side Injection Flash EEPROM Arrays (1995)

Most Flash memories rely on channel hot-electron injection or on Fowler-Nordheim tunnelling for programming. However, Source-Side Injection (SSI) has also been suggested as an alternative programming mechanism since it combines a high injection efficiency with a low power consumption1-6). In the meanwhile, the viability of using this programming mechanism for state-of-the-art nonvolatile applications has been sufficiently demonstrated and the ability to establish fast programming from a single supply voltage has been a driving force for the further qualification of SSI devices5-8). When implementing these novel device structures in memory arrays, the influence of disturb effects in the different operating modes has to be investigated and subsequently minimized by technological or design solutions. Indeed, the outcome of such a disturb analysis is not only a function of the cell structure and of the operating voltages, but also of the array architecture6-8). Particularly for embedded memory applications, technological changes should be avoided in order to maintain a high cost-effectiveness. This paper reports on a critical gate disturb effect in split-gate SSI cells for embedded applications. Different interpoly isolation schemes have been investigated and it is shown that sufficient disturb margin is obtained without major changes to the process flow.
Data Acquisition for Specimen-Specific Computational Models (2009)

Advances in medical imaging techniques and computing power have allowed for the creation of sophisticated joint models that include anatomical soft tissue geometries. However the models still require experimental data of the joint’s mechanical response in order to validate the model and accurately predict joint biomechanics. Experimental methods to acquire data of the joint’s mechanical response have a long history in biomechanics [1], but it has been found that the validation of models [2] based on previously collected experimental data has been difficult because of the large inter-specimen variability. A shift, therefore, has taken place emphasizing the development of specimen specific models. Our aim was to develop a method by which the mechanical response of the knee could be measured and used as input and validation data for a specimen specific computational model.

Liquid droplet imbibition into a thin coating layer: Direct pore-scale modeling and experimental observations (2020)

In order to control ink droplet movement into the printing-paper layer, a set of pore-scale two-phase flow simulations were performed. The high-resolution three-dimensional pore space of the paper was obtained using focused ion beam scanning electron microscopy (FIB-SEM). Solving Navier-Stokes equations yielded details about dynamic movement of a droplet into the layer. To evaluate simulation results, for the first time, confocal laser microscopy imaging technique was integrated into a FIB-SEM chamber. Doing so, high resolution imaging of the droplet penetration inside paper was conducted and computed volume of penetrated ink at final stage was compared to the imaged volume. The ink penetration and spreading extent showed a good agreement with simulation results. Therefore, the developed simulation case was further investigated to study impact of liquid contact angle, real ink properties, and droplet arrival velocity on paper surface on final print quality. A faster penetration into the paper coating was observed for smaller equilibrium contact angles; meanwhile, more radial wicking was observed. In case of velocity of impact, higher velocity caused creation of irregular shapes of the ink footprint on paper surface. In addition to that, higher velocity caused ink splash which consequently created satellite droplets and lowered the print quality. Comparing ink-like liquid (representing real ink liquid properties) with water, water moves faster than ink-like liquid into the paper. This is mainly due to the higher viscosity and lower surface tension of the ink-like liquid.
Role of surgery in the management of primary lymphoma of the gastrointestinal tract (1996)

The role of surgery in the management of primary gastrointestinal lymphoma remains controversial. We retrospectively reviewed the management and outcome of 107 patients with the diagnosis of gastrointestinal lymphoma treated at the UCLA Medical Center during the period 1956-1990. Sixty-four patients underwent surgical exploration at the UCLA Medical Center; 35 of these underwent resection for cure. Sixteen of these 35 patients received no postoperative adjuvant therapy. Twenty-nine patients underwent palliative or "noncurative" resection. There were five postoperative deaths (mortality rate 8%). The overall morbidity rate was 48% There were 3 perforations in a total of 53 patients receiving multiagent chemotherapy. Five-year actuarial survival was as follows: 59% for curative resection alone, 51% for curative resection plus adjuvant therapy, and 28% for "noncurative" resection (P<0.05). Multivariate analysis revealed that stage of disease (P<0.01) and resection for cure (P<0.05) were independent predictors of survival. These results suggest that patients undergoing resection for cure have improved survival. The apparent low risk of perforation during chemotherapy, along with the considerable risk of morbidity and mortality associated with operation, suggests that a policy of debulking large tumors prior to chemotherapy is unwarranted.

Two-level finite difference scheme of improved accuracy order for time-dependent problems of mathematical physics (2010)

In the theory of finite difference schemes, the most complete results concerning the accuracy of approximate solutions are obtained for two- and three-level finite difference schemes that converge with the first and second order with respect to time. When the Cauchy problem is numerically solved for a system of ordinary differential equations, higher order methods are often used. Using a model problem for a parabolic equation as an example, general requirements for the selection of the finite difference approximation with respect to time are discussed. In addition to the unconditional stability requirements, extra performance criteria for finite difference schemes are presented and the concept of SM stability is introduced. Issues concerning the computational implementation of schemes having higher approximation orders are discussed. From the general point of view, various classes of finite difference schemes for time-dependent problems of mathematical physics are analyzed.

Bacteroides endodontalis sp. nov., an Asaccharolytic Black-Pigmented Bacteroides Species from Infected Dental Root Canals (1984)

A new species, Bacteroides endodontalis, is proposed for black-pigmented asaccharolytic Bacteroides strains that have negligible deoxyribonucleic acid homology with either Bacteroides gingivalis or Bacteroides asaccharolyticus. Strain HG370 (= ATCC 35406) is the type strain. Unlike B. gingivalis, B. endodontalis does not agglutinate sheep erythrocytes or produce phenylacetic acid. B. endodontalis resembles B. asaccharolyticus physiologically but can be distinguished by its lower deoxyribonucleic acid guanine-plus-cytosine content (50 versus 53 to 54 mol%), by its serological reactions, by its electrophoretic patterns of proteins, and possibly by its menadione requirement.
miR-10b-5p expression in Huntington’s disease brain relates to age of onset and the extent of striatal involvement (2015)

These results demonstrate that miRNA expression in cortical BA9 provides insight into striatal involvement and support a role for these miRNAs, particularly miR-10b-5p, in HD pathogenicity. The miRNAs identified in our studies of postmortem brain tissue may be detectable in peripheral fluids and thus warrant consideration as accessible biomarkers for disease stage, rate of progression, and other important clinical characteristics of HD.

In this video we present a case of robotic intracorporeal ileal substitution and describe the technique for this minimally invasive procedure. METHODS: The patient was derived to our center due to sepsis after a left ureteroscopy. Imaging revealed total ureteral avulsion that required nephrostomy tube placement. We patient was scheduled months later por robotic ileal interposition. RESULTS: The surgery was done in two phases. The first one included the ileal selection with reconstruction of bowel transit, transposition to the retroperitoneal space below the sigmoid colon, stenting with double J catheter and distal anastomosis to the bladder. The second phase is done in lateral decubitus position. The remnant of the ureter is dissected and sutured to the proximal intestinal end. Total surgical time was 6 hours. The patient had an uneventful postoperative recovery. Both stents were removed at the first month. In the CT scan there was no hydronephrosis and MAG-3 renal scintigraphy showed symmetric radiotracer uptake. CONCLUSIONS: A totally intracorporeal robot assisted ileal interposition is a feasible technique that permits a minimally invasive approach for two different fields.

Triazolopyridines. Part 7. Preparation of bromo-triazolopyridines and -triazoloisoquinolines (1987)

Bromination of the 7-lithiotriazolopyridines (7) and (10) gave small yields of the 7-bromotriazolopyridines (8) and (11). Some ring opening was observed with the lithium derivative (7); ring opening was a major reaction when bromine reacted with 5-lithiotriazoloisoquinoline (15) or with the 7-trimethylsilyltriazolopyridine (20). Good yields of 7-bromotriazolopyridines (8) and (18) and of 5-bromotriazoloisoquinoline (19) were obtained from the appropriate lithio derivative and dibromotetrachloroethane. The properties of 5-trimethylsilyltriazoloisoquinoline and its lithium derivative are reported; protodesilylation has been achieved with compounds (25)–(28).
Following kimberlite indicator minerals to source in the Chidliak Kimberlite Province, Nunavut (2013)

The discovery of diamond-bearing kimberlite within the Chidliak kimberlite province on Hall Peninsula, southern Baffin Island, Nunavut, is a classic example of the application of traditional diamond-exploration techniques in a glaciated terrain. To date, 64 kimberlite pipes have been discovered: 61 on the Chidliak project and three on the adjacent Qilaq project. The first discovery was made in 2008, making Chidliak the most recent kimberlite province discovered in Canada. Comprehensive kimberlite indicator mineral (KIM) classification and interpretation techniques, including abrasion and geochemical analyses have played a significant role in these discoveries and have evolved over the course of the project.

Peri‐implant diseases: diagnosis and risk indicators (2008)

Experimental and clinical studies have identified various diagnostic criteria including probing parameters, radiographic assessment and peri-implant crevicular fluid and saliva analyses. Cross-sectional analyses have investigated potential risk indicators for peri-implant disease including poor oral hygiene, smoking, history of periodontitis, diabetes, genetic traits, alcohol consumption and implant surface. There is evidence that probing using a light force (0.25 N) does not damage the peri-implant tissues and that bleeding on probing (BOP) indicates presence of inflammation in the peri-implant mucosa. The probing depth, the presence of BOP, and suppuration should be assessed regularly for the diagnosis of peri-implant diseases. Radiographs are required to evaluate supporting bone levels around implants. The review identified strong evidence that poor oral hygiene, a history of periodontitis and cigarette smoking, are risk indicators for peri-implant disease. Future prospective studies are required to confirm these factors as true risk factors.
Epitaxial growth and physical properties of a room temperature ferromagnetic semiconductor: Anatase phase Ti1−xCoxO2 (2004)

There has been considerable debate regarding the origin of ferromagnetism in the ferromagnetic semiconductor anatase phase TiO2 doped with Co, ranging from carrier induced ferromagnetism in a framework of diluted magnetic semiconductor to merely the precipitation of ferromagnetic and metallic Co precipitates in the TiO2 matrix. This paper reports on a systematic investigation of the structures, together with the electronic and magneto-optical properties, of thin films of anatase phase TiO2, doped with Co. Films of anatase Ti1−xCoxO2 (x=0–0.10) were grown epitaxially on LaSrAlO4 (001) substrates, using pulsed laser deposition method. In order to control n-type carrier concentration, the oxygen pressure during the growth was systematically varied, yielding films with insulative, semiconductive (carrier concentration n∼1×1017 cm−3), and metallic (n∼2×1019 cm−3) properties. Reflection high energy electron diffraction patterns, atomic force microscopy, and transmission electron microscopy show no evidence of Co segregation in these films. Magneto-optical response was examined by measuring magneto-optical circular dichroism (MCD) spectra at room temperature. A large MCD peak appears at a photon energy close to the band gap of TiO2. The magnetic field dependence of MCD signal indicates ferromagnetic behavior, which is similar to that of the magnetization. The MCD intensity increases systematically with the increase of n or x. Since MCD response originates from charge carriers at the band edge, one can conclude that interaction between the charge carriers and Co impurities is essential to realize ferromagnetism.

Neuroergonomic Assessment of Wheelchair Control Using Mobile fNIRS (2020)

For over two centuries, the wheelchair has been one of the most common assistive devices for individuals with locomotor impairments without many modifications. Wheelchair control is a complex motor task that increases both the physical and cognitive workload. New wheelchair interfaces, including Power Assisted devices, can further augment users by reducing the required physical effort, however little is known on the mental effort implications. In this study, we adopted a neuroergonomic approach utilizing mobile and wireless functional near infrared spectroscopy (fNIRS) based brain monitoring of physically active participants. 48 volunteers (30 novice and 18 experienced) self-propelled on a wheelchair with and without a PowerAssist interface in both simple and complex realistic environments. Results indicated that as expected, the complex more difficult environment led to lower task performance complemented by higher prefrontal cortex activity compared to the simple environment. The use of the PowerAssist feature had significantly lower brain activation compared to traditional manual control only for novices. Expertise led to a lower brain activation pattern within the middle frontal gyrus, complemented by performance metrics that involve lower cognitive workload. Results here confirm the potential of the Neuroergonomic approach and that direct neural activity measures can complement and enhance task performance metrics. We conclude that the cognitive workload benefits of PowerAssist are more directed to new users and difficult settings. The approach demonstrated here can be utilized in future studies to enable greater personalization and understanding of mobility interfaces within real-world dynamic environments.
