On-site Under Voltage Ride Through performance tests &#x2014; Assessment of ENERCON Wind Energy converters based on Hydro-Qu&#x00E9;bec Trans&#x00E9;nergie requirements (2012)

Hydro-Québec Transénergie (HQT) has specific technical requirements for the connection of Wind Power Plants (WPPs). Compliance of specific WPPs with the requirements must be assessed via on-site tests that are described in a companion general validation test program. HQT has worked closely with ENERCON to ensure that the grid code could be fulfilled by its full-converter technology to be used for many projects in the province of Québec. The present paper focuses on the on-site Under Voltage Ride Through (UVRT) tests performed by ENERCON and HQT based on the related requirements. The HQT grid code and validation test program are briefly presented. Furthermore, the theoretical Fault Ride Through (FRT) performance of the ENERCON technology is explained and the testing equipment, setup and limitations are described. Moreover, a few test results are discussed. Finally, some technical issues are presented and corrective measures applied following the tests are explained.
Handover Mechanism in NR for Ultra-Reliable Low-Latency Communications (2018)

For many URLLC services, mobility is a key requirement together with latency and reliability. 3GPP has defined the target of MIT as 0 ms, and a general URLLC reliability requirement as 1 - 10-5 within a latency of 1 ms for 5G. In this article, we analyzed the impact of MIT and handover failure (HOF) rate on the reliability performance. From the analysis, at 120 km/h, with MIT of 0 ms, the required HOF rate to achieve 1 - 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-5</sup> reliability is only 0.52 percent. Therefore, to achieve the reliability for URLLC, we need to minimize not only the MIT but also the HOF rate as close to zero as possible. Hence, we propose conditional make-before- break handover to target zero MIT and zero HOF rate simultaneously. The solution can achieve zero MIT by not releasing the connection to the source cell until the first or some downlink receptions from the target cell. It can achieve the zero HOF rate, by receiving an HO Command message when the radio link to the source cell is still stable, and by executing the handover when the connection to the target cell is preferable. Simulation results show that our proposed solution can achieve almost zero HOF rate even at 120 km/h.

Report on the In-vehicle Auditory Interactions Workshop: Taxonomy, Challenges, and Approaches (2015)

As driving is mainly a visual task, auditory displays play a critical role for in-vehicle interactions.To improve in-vehicle auditory interactions to the advanced level, auditory display researchers and automotive user interface researchers came together to discuss this timely topic at an in-vehicle auditory interactions workshop at the International Conference on Auditory Display (ICAD).The present paper reports discussion outcomes from the workshop for more discussions at the AutoUI conference.
Flaxseed proteins: food uses and health benefits (2011)

Summary Flaxseed proteins are potent multi‐functional ingredients for food formulation owing to their techno‐functionalities, food preservation capacity, and health benefits. A possible synergistic effect with mucilage on their functionalities could be valuable even though this co‐product in flaxseed may limit the protein yield during their production processes. Their techno‐functional properties could also be considered in mixture with other flax bioactive components such as lignans and fibre to enhance the value of the flaxseed meal. The present paper reviews flaxseed protein uses in food and their health benefits. New perspectives according to consumers’ demand for products with health promoting bioactive components are also suggested.
Author response: Chitinase 3-like-1 contributes to acetaminophen-induced liver injury by promoting hepatic platelet recruitment (2021)

Acetaminophen, also called paracetamol outside the United States, is a commonly used painkiller, with over 50 million people in the United States taking the drug weekly. While paracetamol is safe at standard doses, overdose can cause acute liver failure, which leads to 30,000 patients being admitted to emergency care in the United States each year. There is only one approved antidote to overdoses, which becomes significantly less effective if its application is delayed by more than a few hours. This has incentivized research into identify new drug targets that could lead to additional treatment options. Acetaminophen overdose triggers blood clotting and inflammation, contributing to liver injury. It also causes a decrease in cells called platelets circulating in the blood, which has been observed in both mice and humans. In mice, this occurs because platelets accumulate in the liver. Removing these excess cells appears to reduce the severity of the damage caused by acetaminophen, but it remains unclear how the drug triggers their accumulation in the liver. In 2018, researchers showed that a protein called Chi3l1 plays an important role in another form of liver damage. Shan et al. – including many of the researchers involved in the 2018 study – have examined whether the protein also contributes to acetaminophen damage in the liver. Shan et al. showed that mice lacking the gene that codes for Chi3l1 developed less severe liver injury and had fewer platelets in the liver following acetaminophen overdose. They also found that human patients with acute liver failure due to acetaminophen had high levels of Chi3l1 and significant accumulation of platelets in the liver. To test whether damage could be prevented, Shan et al. used antibodies to neutralize Chi3l1 in mice after giving them an acetaminophen overdose. This reduced platelet accumulation in the liver and the associated damage. These findings suggest that targeting Chi3l1 may be an effective strategy to prevent liver damage caused by acetaminophen overdose. Further research could help develop new treatments for acetaminophen-induced liver injury and perhaps other liver conditions.
Inhibition of Dendritic Spine Morphogenesis and Synaptic Transmission by Activity-Inducible Protein Homer1a (2003)

The postsynaptic density (PSD) proteins Shank and Homer cooperate to induce the maturation and enlargement of dendritic spines (Sala et al., 2001). Homer1a is an activity-inducible short-splice variant of Homer that lacks dimerization capacity. Here, we show that Homer1a reduces the density and size of dendritic spines in cultured hippocampal neurons in correlation with an inhibition of Shank targeting to synapses. Expression of Homer1a also decreases the size of PSD-95 clusters, the number of NMDA receptor clusters, and the level of surface AMPA receptors, implying a negative effect on the growth of synapses. In parallel with the morphological effects on synapses, Homer1a-expressing neurons show diminished AMPA and NMDA receptor postsynaptic currents. All of these outcomes required the integrity of the Ena/VASP Homology 1 domain of Homer1a that mediates binding to the PPXXF motif in Shank and other binding partners. Overexpression of the C-terminal region of Shank containing the Homer binding site causes effects similar to those of Homer1a. These data indicate that an association between Shank and the constitutively expressed long-splice variants of Homer (e.g., Homer1b/c) is important for maintaining dendritic-spine structure and synaptic function. Because Homer1a expression is induced by synaptic activity, our results suggest that this splice variant of Homer operates in a negative feedback loop to regulate the structure and function of synapses in an activity-dependent manner.
Low-Complexity Beamforming Techniques for IEEE 802.11n WLANs (2009)

The impetus of the present study is to describe a downlink beamforming method that increase spectrum efficiency and significantly reduces implementation complexity and power consumption compare to beamforming technique at each sub-carrier, proposed in the ongoing IEEE 802.11n standardization. In our scheme, common transmission weight vectors are used at a set of users in all sub-carriers. Our strategy consists of simultaneously designing downlink beamformers to multiple co-channel sets of users under the constraint on providing at least a prescribed received signal-to-interference plus noise ratio (SINR) to each intended receiver. We assume that the instantaneous channel gains are known at the access point (AP) for all users. Simulation results show substantial gain for our proposed algorithms in IEEE 802.11n wireless access networks.
Chronic clozapine reduces rat brain arachidonic acid metabolism by reducing plasma arachidonic acid availability (2012)

Chronic administration of mood stabilizers to rats down-regulates the brain arachidonic acid (AA) cascade. This down-regulation may explain their efficacy against bipolar disorder (BD), in which brain AA cascade markers are elevated. The atypical antipsychotics, olanzapine (OLZ) and clozapine (CLZ), also act against BD. When given to rats, both reduce brain cyclooxygenase activity and prostaglandin E(2) concentration; OLZ also reduces rat plasma unesterified and esterified AA concentrations, and AA incorporation and turnover in brain phospholipid. To test whether CLZ produces similar changes, we used our in vivo fatty acid method in rats given 10 mg/kg/day i.p. CLZ, or vehicle, for 30 days; or 1 day after CLZ washout. [1-(14) C]AA was infused intravenously for 5 min, arterial plasma was collected and high-energy microwaved brain was analyzed. CLZ increased incorporation coefficients ki * and decreased [corrected] rates J(in,i) of plasma unesterified AA into brain phospholipids. [corrected]. These effects disappeared after washout. Thus, CLZ and OLZ similarly down-regulated kinetics and cyclooxygenase expression of the brain AA cascade, likely by reducing plasma unesterified AA availability. Atypical antipsychotics and mood stabilizers may be therapeutic in BD by down-regulating, indirectly or directly respectively, the elevated brain AA cascade of that disease.
Self Emulsifying Drug Delivery System: A Review (2008)

Oral route still remains the favorite route of drug administration in many diseases and till today it is the first way investigated in the development of new dosage forms. The major problem in oral drug formulations is low and erratic bioavailability, which mainly results from poor aqueous solubility. This may lead to high inter- and intra subject variability, lack of dose proportionality and therapeutic failure. It is estimated that 40% of active substances are poorly soluble in water. The improvement of bio-availability of drugs with such properties presents one of the greatest challenges in drug formulations. Various technological strategies are reported in the literature including micronization, solid dispersions or cyclodextrines complex formation and different technologies of drug delivery systems. Among various approach selfemulsifying drug delivery system has gained more attention due to enhanced oral bio-availability enabling reduction in dose, more consistent temporal profiles of drug absorption, selective targeting of drug(s) toward specific absorption window in GIT, and protection of drug(s) from the hostile environment in gut.
Flexural Behaviour of Encased Composite Beam with Precast Hollow Core Slabs and Channels (2008)

This paper deals with the experimental analysis of the flexural behaviour of encased composite beams with hollow core slabs and channels. The shear force between steel beams and hollow core slabs are transferred by channels. Three full-scale specimens were constructed and tested with different steel beam heights, which were compared with those of previous studies. Based on observation of the experiments, the encased composite beams exhibited full shear connection behaviour without any other shear connectors due to their inherent mechanical and chemical bond stress. Experimental results show a behaviour similar to steel-concrete composite beams with classical connectors: elastic and yield domains, great ductility, flexural failure mode (plastic hinge), low relative movement at steel-concrete interface and all specimens failed in a very ductile manner. Consequently, this study enables the validation of the proposed connection device under static loading and shows that it meets modern structural requirements.
Noise2Void - Learning Denoising from Single Noisy Images (2018)

The field of image denoising is currently dominated by discriminative deep learning methods that are trained on pairs of noisy input and clean target images. Recently it has been shown that such methods can also be trained without clean targets. Instead, independent pairs of noisy images can be used, in an approach known as Noise2Noise (N2N). Here, we introduce Noise2Void (N2V), a training scheme that takes this idea one step further. It does not require noisy image pairs, nor clean target images. Consequently, N2V allows us to train directly on the body of data to be denoised and can therefore be applied when other methods cannot. Especially interesting is the application to biomedical image data, where the acquisition of training targets, clean or noisy, is frequently not possible. We compare the performance of N2V to approaches that have either clean target images and/or noisy image pairs available. Intuitively, N2V cannot be expected to outperform methods that have more information available during training. Still, we observe that the denoising performance of Noise2Void drops in moderation and compares favorably to training-free denoising methods.
8 Communication Awareness (2022)

The ubiquity of connected devices and parallel computing platforms challenges efficient and reliable execution of machine learning algorithms. If machine learning workloads are executed merely locally, a system does not always have sufficient resources at its disposal to perform the necessary operations fast enough. Furthermore, at a smaller scale, multiple hardware components these days are interconnected via on-chip or off-chip networks to create many-core systems. Communication, synchronization, and offloading have thus become essential in designing embedded systems under communication and resource constraints.
Cystourethrography in Women (1952)

Accurate radiological visualisation of the urethra, urethrovesical junction and bladder base is assuming increasing importance in the study of mechanical disturbances of these structures in women suffering from stress incontinence of urine. It is also valuable as a means of controlling the operative or non-operative treatment of this trouble-some complaint, and it offers a means, hitherto neglected, of research into the anatomy and physiology of the female bladder and urethra. Adequate study of the female urinary apparatus demands radiography in at least two planes and with the organs in different functional states. Significant departures from the normal may become apparent only when the patient is straining or voiding urine. The technical problems involved have hindered many workers in the past, but they can be overcome, and the object of this communication is to describe methods which have been used regularly for two years and which make it possible for cystourethrography to be carried out as a routine procedure in any X-ray department. Cystourethrography has been used in the male for more than forty years, but the first attempt to apply it to women appears to be that of Norris and Kimbrough (1928), who studied both normal and incontinent women by means of antero-posterior skiagraphs. The advantages offered by lateral views were appreciated by Thomsen (1930, 1932), but the difficulties involved forced him to resort to 45 deg. oblique exposures of the pelvic organs.
A Practical Guide for Implementing Evidence-Based Assessment in a Psychiatric Residential Treatment Facility: Translating Theory Into Practice (2011)

This article provides specific and practical guidelines for how to set up and implement an assessment protocol in a psychiatric residential treatment facility (PRTF) setting for the purposes of informing administrators and therapists of their residents' current and changing mental health status throughout the course of treatment. The assessment protocol we propose and recommend is (a) based on empirically supported research, (b) relatively inexpensive, (c) easy to administer, and (d) provides easily interpretable information to therapists. This protocol was also well-implemented at a child and adolescent PRTF located in the southern region of the United States (N = 254) and was well-received by staff therapists (N = 6). The current article may be used as a "How-To" guide for implementing an evidence-based assessment protocol in PRTFs to translate theory into practice.
Dynamic Reconfiguration and Load Distribution in Component Middleware (2003)

Large-scale distributed systems, such as telematics systems, are often built using component-middleware technologies (e.g., CORBA). Middleware offers distribution transparencies. This means that complexities related to the distribution are hidden from the application developers by embedding the distribution aspects in the middleware. Component middleware is middleware that uses component concepts such as encapsulation and well-defined interfaces. This thesis proposes a new approach for the design of Quality of Service (QoS) mechanisms in component middleware. The specific QoS mechanisms that we propose in this thesis are (i) a new dynamic reconfiguration mechanism, which improves the availability by allowing online replacements and migrations of application components, and (ii) a new load distribution mechanism, which improves the performance of application components. Important characteristics of these QoS mechanisms are: (i) they are dynamic, (ii) they do not rely on specific network or operating system QoS functionality, and (iii) they are transparent for the developer of application components. We achieve transparency by using message reflection techniques in the middleware layer. A CORBA-based prototype serves as a proof of concept for our approach and our QoS mechanisms. M
Sliding Walk With Friction Control of Double-Network Gel on Feet of Inchworm Robot (2019)

Soft-matter robotics, which is named for robots made from soft materials, will possibly conquer the limit of conventional rigid body dynamics of hard robots made from hard materials. For example, a snake-like robot, of which body is made from soft materials, will walk in various environments including narrow space like drain pipes with complicated structure. Here we developed a walking robot with the friction control of double-network hydrogel (DN gel) on its feet, as the first model based on the concept of the soft-matter robotics. It is found that with appropriate control of the friction of DN gel, the inchworm walking robot has realized its high enough velocity for pipe inspection. We discussed the physical principle of the walking motion of the inchworm search robot and its actual mechanism to provide thrust for its walking motion.
Resolution improvement in digital holography: comparison between synthetic aperture method and spatial averaging method (2011)

In the last two decades digital holography emerged as one of the most promising techniques for obtaining the complex object-wave (amplitude and phase). However, due to the coherent nature of the light source used in digital holography, the reconstructed hologram is subjected to speckle noise. Moreover, the resolution and size of the sensor employed in digital holography are smaller compared to the formerly used holographic plates in optical holography. This results in a reduced resolution for the reconstructed hologram. This paper discusses two resolution improvement methods, which are both based on the same recording process. However, the recorded data is processed differently to obtain a resolution improved reconstruction. The two methods are compared in terms of corresponding optical resolution, phase accuracy and processing time.
Synthesis and Characterization of Novel Forward Osmosis Membranes based on Layer-by-Layer Assembly (2011)

Forward osmosis (FO) has received considerable interest for water- and energy-related applications in recent years. FO does not require an applied pressure and is believed to have a low fouling tendency. However, a major challenge in FO is the lack of high performance FO membranes. In the current work, novel nanofiltration (NF)-like FO membranes with good magnesium chloride retention were synthesized using layer-by-layer (LbL) assembly. The membrane substrate was tailored (high porosity, finger-like pores, thin cross-section, and high hydrophilicity) to achieve a small structural parameter of 0.5 mm. Increasing the number of polyelectrolyte layers improved the selectivity of the LbL membranes while reducing their water permeability. The more selective membrane 6#LbL (with 6 polyelectrolyte layers) had much lower reverse solute transport compared to 3#LbL and 1#LbL. Meanwhile, the FO water flux was found to be strongly affected by both membrane water permeability and solute reverse transport. Severe solute reverse transport was observed for the active-layer-facing-draw-solution membrane orientation, likely due to the suppression of Donnan exclusion as a result of the high ionic strength of the draw solution. In contrast, the active-layer-facing-feed-solution orientation showed remarkable FO performance (15, 20, and 28 L/m².h at 0.1, 0.5, and 1.0 M MgCl₂, respectively, for membrane 3#LbL using distilled water as feed solution), superior to other NF-like FO membranes reported in the literature. To the best of the knowledge of the authors, this is the first work on the synthesis and characterization of LbL based FO membranes.
People Counting System for Getting In/Out of a Bus Based on Video Processing (2008)

This paper presents an automatic people counting system for getting in/out of a bus based on video processing. The basic scheme is to set a zenithal camera in the bus for capturing the passenger flow bi-directionally. The captured frame is firstly divided into many blocks and each block will be classified according to its motion vector. If the block quantity of similar motion vectors is more than a threshold, those blocks are regarded as belonging to the same moving object. As a result, the number of such moving objects is counted to be the passenger number of getting in or out of a bus. can be segmented for counting. Experimental results show that the proposed bus-passenger counting algorithm can provide a high count accuracy of 92% on average.
