Quantitative microfocal radiographic assessment of disease and progression in osteoarthritis of the hand. (1991)

Macroradiographic examination of the wrists and hands of 32 patients with osteoarthritis (OA) over an 18 month period showed that, compared with healthy control subjects, 44% of the patients had significant joint space narrowing at entry, which increased to 65%. Subchondral cortical thickness was greater in all patients at entry and increased with time. Osteophytes and juxtaarticular radiolucencies were present in all patients at study entry; by the end, osteophytes had increased in number and area, and juxtaarticular radiolucencies in area only. We conclude that in OA of the hand, bony changes have progressed significantly before joint space narrowing.
You and your mentor (1997)

Abstract The purpose of this paper is to illustrate a way in which your mentor should provide opportunities for you as a newly qualified teacher (NQT) to engage in the spiral process of evaluation, reflection and review as a means of achieving continuous professional development. The role of your mentor in this approach is to provide these opportunities in order to enable reflection to take place, in turn facilitating your progress as a NQT from one ‘phase’ of development to the next.
A Case of Herpes Zoster Ophthalmicus with Isolated Trochlear Nerve Involvement (2011)

Isolated trochlear nerve involvement associated with HZO is very rare and may be easily overlooked. Physicians should carefully examine oculomotor involvement in HZO.
Effect of Different Terpene-Containing Essential Oils on Percutaneous Absorption of Trazodone Hydrochloride Through Mouse Epidermis (2006)

The aim of our study was to investigate the enhancing effect of several essential oils in the percutaneous absorption of trazodone hydrochloride (TZN). For this purpose, fennel oil, eucalyptus oil, citronella oil, and mentha oil were applied on the skin membrane in three different ways: included in the transdermal device, as a pretreatment, or both. To investigate the effect of penetration enhancers used in this study on the percutaneous absorption of TZN through mouse epidermis, Keshary-Chien diffusion cells were employed. The receptor phase was constantly stirring saline phosphate buffer of pH 7.4 at 37 +/- 1 degrees C. Results showed that pretreatment of skin with essential oils increases the flux values of TZN compared with the values obtained when the same essential oils were included in the transdermal devices. The percutaneous penetration flux for TZN was increased with skin pretreatment by 10% essential oils in the following order: fennel oil > eucalyptus oil > citronella oil > mentha oil. The amount of TZN retained in the skin after pretreatment with essential oils was found to be very similar in all cases and much higher than in the experiments without skin pretreatment.
Prognostic role of high B7-H4 expression in patients with solid tumors: a meta-analysis (2016)

This meta-analysis clarified that high B7-H4 expression in tissue was significantly associated with poor survival in patients with solid tumors. Future clinical studies are warranted to determine whether B7-H4 blockade has a favorable effect on disease recurrence and mortality.
Relacions del monestir de Santes Creus amb l'antic orde de Montesa (1975)

Heterotrimeric G proteins are classified into four subfamilies and play a key role in signal transduction. They transmit extracellular signals to intracellular effectors subsequent to the activation of G protein-coupled receptors (GPCRs), which are targeted by over 30 % of FDA-approved drugs. However, addressing G proteins as drug targets represents a compelling alternative, for example, when G proteins act independently of the corresponding GPCRs, or in cases of complex multifunctional diseases, when a large number of different GPCRs are involved. In contrast to Gαq, efforts to target Gαi/s by suitable chemical compounds has not been successful so far. Here, a comprehensive analysis was conducted examining the most important interface regions of Gαi/s with its upstream and downstream interaction partners. By assigning the existing compounds and the performed approaches to the respective interfaces, the druggability of the individual interfaces was ranked to provide perspectives for selective targeting of Gαi/s in the future.
A compact model of MOSFET mismatch for circuit design (2005)

This paper presents a compact model for MOS transistor mismatch. The mismatch model uses the carrier number fluctuation theory to account for the effects of local doping fluctuations along with an accurate and compact dc MOSFET model. The resulting matching model is valid for any operation condition, from weak to strong inversion, from the linear to the saturation region, and allows the assessment of mismatch from process and geometric parameters. Experimental results from a set of transistors integrated on a 0.35 /spl mu/m technology confirm the accuracy of our mismatch model under various bias conditions.
Hierarchical directed acyclic graph kernel (2006)

This paper devises a novel kernel function for natural language processing tasks. The new kernels, called Hierarchical Directed Acyclic Graph (HDAG) kernels, directly accept graphs whose nodes could contain graphs. HDAG data structures are needed to fully reflect the syntactic and semantic structures inherently possessed by natural language data. In this paper, we define the kernel function and describe how to achieve efficient calculation. Experimental results demonstrate that the proposed kernels are superior to other kernel functions, sequence kernels, dependency structure kernels, and bag-of-words kernels. © 2006 Wiley Periodicals, Inc.

Morphology and water vapor permeability of temperature‐sensitive polyurethanes (2007)

Abstract A series of segmented polyurethanes (PUs) were prepared, in which five different polyols and hexamethylene diisocyanate were used as soft segments, and 4,4′‐diphenylmethane diisocyanate, hydrophilic segment poly (ethylene glycol) 200 (PEG 200), and chain extender 1,4‐butanediol were used as hard segment. Morphology of the PUs was investigated using differential scanning calorimetry, wide angle X‐ray diffraction, polarizing microscopy, and transmission electron microscopy. Water vapor permeability of the membranes as a function of temperature was tested accordingly. Results show that the presence of PEG200 interferes the crystallization of hard segment in these PUs, and at the same time, increases phase compatibility between soft and hard segment in the PET‐PU. It leads to a lower crystal melting temperature and degree of crystallinity of soft segment in the segmented PU than those of pure polyols, and no crystallization existing in hard segment. A morphological model is proposed, that is, aggregated soft‐segment‐rich domains can be observed clearly in the PUs with high crystallinity in soft segment, while identifiable hard domains are well‐distributed in the soft segment domains in the PU with low crystallinity. Within the temperature range of crystal melting, water vapor permeability of the PU membranes increases significantly with increase of temperature. Such temperature‐sensitive property is triggered by crystal melting of soft segment. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci, 2008

Partitioning analog and digital processing in a single-chip GPS receiver (2002)

In the near future, Global Positioning System (GPS) data will be used in a wide variety of portable, mobile electronic devices. Shrinking feature sizes, combined with the need for low-power, lightweight components, will drive an entire GPS receiver onto a single, mixed-signal die. A major design issue in mixed-signal systems is the effect of digital switching noise coupled to sensitive analog circuits through the substrate. A method is proposed for minimizing this effect by partitioning digital and analog processing into separate time blocks. The resulting trade-off between lost signal and increased energy consumption is explored. In particular, a GPS synchronizer design is analyzed with respect to modifications that can be made to increase performance, while minimizing any associated energy penalty.
Proteolysis of proBDNF Is a Key Regulator in the Formation of Memory (2008)

It is essential to understand the molecular processes underlying long-term memory to provide therapeutic targets of aberrant memory that produce pathological behaviour in humans. Under conditions of recall, fully-consolidated memories can undergo reconsolidation or extinction. These retrieval-mediated memory processes may rely on distinct molecular processes. The cellular mechanisms initiating the signature molecular events are not known. Using infusions of protein synthesis inhibitors, antisense oligonucleotide targeting brain-derived neurotrophic factor (BDNF) mRNA or tPA-STOP (an inhibitor of the proteolysis of BDNF protein) into the hippocampus of the awake rat, we show that acquisition and extinction of contextual fear memory depended on the increased and decreased proteolysis of proBDNF (precursor BDNF) in the hippocampus, respectively. Conditions of retrieval that are known to initiate the reconsolidation of contextual fear memory, a BDNF-independent memory process, were not correlated with altered proBDNF cleavage. Thus, the processing of BDNF was associated with the acquisition of new information and the updating of information about a salient stimulus. Furthermore, the differential requirement for the processing of proBDNF by tPA in distinct memory processes suggest that the molecular events actively engaged to support the storage and/or the successful retrieval of memory depends on the integration of ongoing experience with past learning.

Simulation of a Smart Grid City with Software Agents (2009)

In the future smart city, new information and communication technologies will enable a better management of the available resources. The future smart grid infrastructure is emerging as a complex system where fine-grained monitoring and control of energy generating and/or consuming entities within the electricity network is possible. This will result to better approaches that will boost energy efficiency. A simulation of a dynamic ecosystem such as the smart city, will enable us to test new concepts and resource-optimization approaches. Therefore we have analyzed, designed, and build a simulator based on software agents that attempts to create the dynamic behavior of a smart city. It simulates discrete heterogeneous devices that consume and/or produce energy, that are able to act autonomously and collaborate. The behavior of these devices and their groupings e.g. smart houses, has been modeled in order to map as near as possible the real behavior patterns of the respective physical objects.
Interval Based X-Masking for Scan Compression Architectures (2008)

Test stimulus and response compaction (scan compression) in scan is increasingly becoming an integral part of today's design-for-test (DFT) methodology for achieving high quality test at lower costs. Current generation integrated circuit's (ICs) are very complex designs that produce a large number of unknown values (Xs) during response capture in scan testing. Response compaction techniques have been shown to be very effective in dealing with any distribution of the Xs while not compromising on the test coverage. However, as the number of scan in pins reduce, the X-tolerance capability of these techniques degrades rapidly. In this paper we discuss interval based response compaction scheme for scan compression architectures. We present an analysis to show that very high X-tolerance can be achieved with a small number of scan-in pins and with no loss of test coverage. We also show that this eventually translates into higher compression ratio and lower test data volume.
On the RFID Wake-up Impulse for Multi-hop Sensor Networks (2007)

Communication protocols for wireless sensor networks reduce the energy consumption by duty cycling the node activity and adopting a periodic sleeping scheduling. This approach often results in idle listening and therefore energy dissipated for listening to a channel free from packet transmitted. Duty cycling trades-off energy consumption due to idle listening and high end-to-end delay. Proposed solutions mitigate this issue for example through extra low-power radio components (wake-up radio) that listen to the radio and wake-up the node if some channel activity is sensed. These extra components also consume some energy to listen to the channel. In contrast, we propose an on-demand wake-up capability, namely RFIDimpulse, which is achieved through using an off-the-shelf battery-less RFID tag attached to each sensor node that is also provided with RFID reader capability. Because modern RFID techniques can trigger all the neighbouring tags at once or pinpoint a particular tag, RFIDimpluse provides both unicast and multicast capability. RFIDimpulse allows event-driven communication and eliminates node idle listening. 1

Laboratory Directed Research & Development Program. Annual report to the Department of Energy, Revised December 1993 (1993)

At Brookhaven National Laboratory the Laboratory Directed Research and Development (LDRD) Program is a discretionary research and development tool critical in maintaining the scientific excellence and vitality of the laboratory. It is also a means to stimulate the scientific community, fostering new science and technology ideas, which is the major factor in achieving and maintaining staff excellence, and a means to address national needs, within the overall mission of the Department of Energy and Brookhaven National Laboratory. This report summarizes research which was funded by this program during fiscal year 1993. The research fell in a number of broad technical and scientific categories: new directions for energy technologies; global change; radiation therapies and imaging; genetic studies; new directions for the development and utilization of BNL facilities; miscellaneous projects. Two million dollars in funding supported 28 projects which were spread throughout all BNL scientific departments.
Assessing the Generalizability of Managerial Discretion: An Empirical Investigation in the Arab World (2017)

The purpose of this paper is to examine the generalizability of national-level managerial discretion and to assess whether the national context play a role in changing mainstream research findings. Based on a sample of three Arabian countries and using a panel of prominent cross-cultural scholars who provided 138 discretion scores for the sampled countries, we replicate the national framework of Crossland and Hambrick (2011) in a new cultural context. The cultural dimensions were measured via survey responses of 375 middle-managers based on House et al. (2004) cultural practices scale. Consistent with Crossland and Hambrick (2011), we demonstrate that individualism and uncertainty tolerance have the same positive effect on CEOs discretion even in a different cultural setting. In contrast, we show that power distance has a positive and significant effect on managerial discretion. Our results indicate that executives can take idiosyncratic and bold actions to the extent to which the cultural environment allows them to do so. Accordingly, we contribute by showing the importance of the national setting in affecting the generalizability of discretion findings.
Microfabricated grooves recapitulate neonatal myocyte connexin43 and N‐cadherin expression and localization (2003)

Our objective is to alter the surface topography on which cardiac myocytes are grown in culture so that they more closely resemble their in vivo counterparts. Microtextured silicone substrata were made using photolithography and microfabrication techniques and then coated with laminin. Primary cardiac myocytes from newborn rats were plated on microgrooved and nontextured substrata. Myocytes were highly oriented on 5 microm grooves (69.8 +/- 2.0%) and significantly different, p < 0.0001, compared with randomly oriented cells grown on nontextured surfaces (2.9 +/- 0.95%; n = 19). Cells on shallower, 2 microm, grooves were slightly less well oriented (46.9 +/- 4.3%, n = 5, p < 0.001). The lateral spacings of the grooves were altered to examine changes in cell-to-cell contact by confocal immunocytochemistry and quantitative protein analysis. Connexin43 and N-cadherin were distributed around the perimeter of the myocytes plated on 10 x 5 x 5 microgrooved surfaces, similar to the localization found in the neonate. Connexin43 expression in cultures on 5 microm deep grooved substrata was equal to the neonatal heart, whereas it differed in nontextured surfaces. We conclude that it is necessary to combine groove depth (5 microm) and lateral ridge dimensions between grooves (5 microm) in order to recapitulate connexin43 and N-cadherin expression levels and subcellular localization to that of the neonate.
The Virtual Mitten: A novel interaction paradigm for visuo-haptic manipulation of objects using grip force (2014)

In this paper, we propose a novel visuo-haptic interaction paradigm called the “Virtual Mitten” for simulating the 3D manipulation of objects. Our approach introduces an elastic handheld device that provides a passive haptic feedback through the fingers and a mitten interaction metaphor that enables to grasp and manipulate objects. The grasping performed by the mitten is directly correlated with the grip force applied on the elastic device and a supplementary pseudo-haptic feedback modulates the visual feedback of the interaction in order to simulate different haptic perceptions. The Virtual Mitten allows natural interaction and grants users with an extended freedom of movement compared with rigid devices with limited workspaces. Our approach has been evaluated within two experiments focusing both on subjective appreciation and perception. Our results show that participants were able to well perceive different levels of effort during basic manipulation tasks thanks to our pseudo-haptic approach. They could also rapidly appreciate how to achieve different actions with the Virtual Mitten such as opening a drawer or pulling a lever. Taken together, our results suggest that our novel interaction paradigm could be used in a wide range of applications involving one or two-hand haptic manipulation such as virtual prototyping, virtual training or video games.
