Convex Relaxations of Chance Constrained AC Optimal Power Flow (2017)

High penetration of renewable energy sources and the increasing share of stochastic loads require the explicit representation of uncertainty in tools such as the optimal power flow (OPF). Current approaches follow either a linearized approach or an iterative approximation of nonlinearities. This paper proposes a semidefinite relaxation of a chance-constrained AC-OPF, which is able to provide guarantees for global optimality. Using a piecewise affine policy, we can ensure tractability, accurately model large power deviations, and determine suitable corrective control policies for active power, reactive power, and voltage. We state a tractable formulation for two types of uncertainty sets. Using a scenario-based approach and making no prior assumptions about the probability distribution of the forecast errors, we obtain a robust formulation for a rectangular uncertainty set. Alternatively, assuming a Gaussian distribution of the forecast errors, we propose an analytical reformulation of the chance constraints suitable for semidefinite programming. We demonstrate the performance of our approach on the IEEE 24 and 118 bus system using realistic day-ahead forecast data and obtain tight near-global optimality guarantees.
Longitudinal study of intraneural perineurioma--a benign, focal hypertrophic neuropathy of youth (2009)

The natural history of intraneural perineurioma has been inadequately studied. The aim of this study was to characterize the clinical presentation, electrophysiologic and imaging features and outcome of intraneural perineurioma. We ask if intraneural perineurioma is a pure motor syndrome that remains confined to one nerve and should be treated by surgical resection. We examined the nerve biopsies of cases labelled perineurioma and selected those with diagnostic features. Thirty-two patients were identified; 16 children and 16 adults; 16 males and 16 females. Median age of onset of neurological symptoms was 14 years (range 0.5-55 years) and median age at evaluation was 17 years (range 2-56 years). All patients had motor deficits; however, mild sensory symptoms or signs were experienced by 27 patients; 'prickling' or 'asleep numbness' in 20, mild pain in 13 and sensory loss in 23. The sciatic nerve or its branches was most commonly affected in 15, followed by brachial plexus, radial nerve and ulnar nerve (four each). Magnetic resonance imaging demonstrated nerve enlargement (29/32), T1 isointensity (27/32), T2 hyperintensity (25/32) and contrast enhancement (20/20). Diagnoses were made based on targeted biopsy of the focal nerve enlargement identified by imaging. Neurological impairment was of a moderate severity (median Neuropathy Impairment Score was 12 points, range 2-49 points). All patients had focal involvement with 27 involving one nerve and five involving a plexus (one bilateral). Long-term follow-up was possible by telephone interview for 23 patients (median 36 months, range 2-177 months). Twelve patients also had follow-up neurologic evaluation (median 45 months, range 10-247 months). The median Neuropathy Impairment Score had changed from 12.6 to 15.4 points (P = 0.19). In all cases, the distribution of neurologic findings remained unchanged. Median Dyck Disability Score was 3 (range 2-5) indicating a mild impairment without interfering with activities of daily living. Ten patients judged their symptoms unchanged, nine slightly worse and four slightly better. We conclude intraneural perineurioma is a benign hypertrophic (non onion bulb) peripheral nerve tumour that presents insidiously in young people and is motor predominant with mild sensory involvement. It is most often a mononeuropathy, but a plexopathy can occur. Diagnosis of this condition requires clinical suspicion, imaging, targeted fascicular biopsy of the lesion and expertise of nerve pathologists. As these tumours are static or slowly progressive, remain confined to their original distribution and have low morbidity, they probably should not be resected routinely. Because intensive evaluation is needed for diagnosis, intraneural perineurioma is probably under-recognized.

Formation and Luminescence Enhancement of Agglomerate-Free YAG:Ce[sup 3+] Submicrometer Particles by Flame-Assisted Spray Pyrolysis (2007)

particles were successfully fabricated by flame-assisted spray pyrolysis (FASP) combined with low-temperature annealing. The direct synthesis by FASP produced in the hexagonal phase. However, the phase changed completely to the garnet phase after being heat-treated at a temperature as low as for . The heat-treated particles were spherical and nonagglomerated. Increasing annealing temperature as well as annealing time improved the particles' crystallinity. The heat-treated particles showed a photoluminescence (PL) intensity comparable to that of commercial products prepared by the solid-state method. In addition, plotting the particles' crystallinity and PL intensity showed the direct correlation between both parameters. In short, improvement of the particles' crystallinity intensified the PL intensity. Comparing the particles' measured and calculated sizes led to the conclusion that particle formation by FASP can be considered as a one-droplet-to-one-particle mechanism.
P0973ALLOSTERIC C-C CHEMOKINE RECEPTOR TYPE 2 (CCR2) INHIBITION IMPROVES RENAL FUNCTION IN A MURINE MODEL OF DIABETIC NEPHROPATHY (2020)

Abstract Background and Aims Diabetic nephropathy (DN) is a syndrome characterized by pathological levels of proteinuria, glomerular lesions and reduction in the glomerular filtration rate (GFR) in diabetic patients. Several lines of evidence support a role of CCR2 in the pathogenesis of DN. Recent studies have demonstrated that existing small molecule CCR2 antagonists can be placed in two classes, distinguished by their interaction with one of two distinct binding sites on CCR2: an extracellular site for which antagonists compete directly with native ligands (the orthosteric site), or an intracellular allosteric binding site. To better understand the functional differences between these antagonists we compared an example of each class in a murine model of DN. Our results revealed that the allosteric, but not the orthosteric CCR2 inhibitors ameliorated the proteinuria and improved glomerular histopathology in this model of DN. Method We used db/db mice to model DN. Several structurally distinct CCR2 inhibitors with that bind to either the allosteric (CCR2-RA-[R] and CCX872) or orthosteric (MK-0812 and CCX598) sites were compared. Pharmacokinetic (PK) properties and renal functional parameters were assessed, including trough drug levels and proteinuria (urinary albumin excretion rate UAER; urine albumin creatinine ratio UACR). Histopathology and electron microscopy (EM) were performed to assess any potential tissue-protective effects of the antagonists. Results Both the allosteric inhibitors (CCR2-RA-[R] and CCX872) and the orthosteric inhibitors (MK-0812 and CCX598) were potent CCR2 antagonists with desirable PK in mouse in so far as both classes effectively blocked CCR2-mediated monocyte migration into the peritoneal cavity in the thioglycollate-induced peritonitis model. At comparable drug coverage levels, CCR2-RA-[R] and CCX872 rapidly and significantly reduced UAER/UACR (CCX872: 70 % at day 7 vs vehicle, p&amp;lt;0.0001; and 60 % at day 14 vs vehicle, p=0.001; CCR2-RA-[R]: 60 % at day 7 vs vehicle, p=0.0001; and 58 % at day 14 vs vehicle, p=0.005), but MK-0812 and CCX598 did not exhibit proteinuria lowering effect. Histological parameters including glomerular injury and glomerular basement membrane (GBM) thickness were also improved after CCX872 treatment in db/db mice. Conclusion Allosteric antagonists of CCR2 provide significant and rapid renal protection in the db/db murine model of DN, as evidenced by improvements in renal function and histological parameters, while potent orthosteric CCR2 antagonists were not effective in the model. Our data suggest that targeting the effectiveness of CCR2 antagonists in DN are directly dependent on binding to the allosteric site of CCR2.
Bax Inhibitor-1 Is a pH-dependent Regulator of Ca2+ Channel Activity in the Endoplasmic Reticulum (2008)

In this study, Bax inhibitor-1 (BI-1) overexpression reduces the ER pool of Ca(2+) released by thapsigargin. Cells overexpressing BI-1 also showed lower intracellular Ca(2+) release induced by the Ca(2+) ionophore ionomycin as well as agonists of ryanodine receptors and inositol trisphosphate receptors. In contrast, cells expressing carboxyl-terminal deleted BI-1 (CDelta-BI-1 cells) displayed normal intracellular Ca(2+) mobilization. Basal Ca(2+) release rates from the ER were higher in BI-1-overexpressing cells than in control or CDelta-BI-1 cells. We determined that the carboxyl-terminal cytosolic region of BI-1 contains a lysine-rich motif (EKDKKKEKK) resembling the pH-sensing domains of ion channels. Acidic conditions triggered more extensive Ca(2+) release from ER microsomes from BI-1-overexpressing cells and BI-1-reconstituted liposomes. Acidic conditions also induced BI-1 protein oligomerization. Interestingly subjecting BI-1-overexpressing cells to acidic conditions induced more Bax recruitment to mitochondria, more cytochrome c release from mitochondria, and more cell death. These findings suggest that BI-1 increases Ca(2+) leak rates from the ER through a mechanism that is dependent on pH and on the carboxyl-terminal cytosolic region of the BI-1 protein. The findings also reveal a cell death-promoting phenotype for BI-1 that is manifested under low pH conditions.
Decoupling contact and mirror: an effective way to improve the reflector for flip-chip InGaN/GaN-based light-emitting diodes (2016)

In the conventional fabrication process of the widely-adopted Ni/Ag/Ti/Au reflector for InGaN/GaN flip-chip light-emitting diodes (LEDs) the contact and the mirror are entangled together with contrary processing conditions which set constraints to the device performance severely. Here we first report the concept and its effectiveness of decoupling the contact formation and the mirror construction. The ohmic contact is first formed by depositing and annealing an extremely thin layer of Ni/Ag on top of p-GaN. The mirror construction is then carried out by depositing thick layer of Ag/Ti/Au without any annealing.
Development of G-Vectoring Control system based on engine torque control (2016)

For the enhanced driving quality for human drivers, it is crucial to realize the harmonious transition between lateral and longitudinal motions. We have focused on G-Vectoring Control (GVC) which controls longitudinal acceleration in coordination with lateral acceleration. While the past researches applied brake control or electric motor control to decelerate the vehicle, the significance of the newly developed GVC is to use the high-response internal combustion engine to improve vehicle dynamics. Though the amount of engine torque reduction with the system is smaller than the engine brake, the system’s benefits were confirmed in various driving situations such as cornering and straight ahead driving. In this paper, after the system configuration is described, its control effects are evaluated through the field tests in objective and subjective aspects. Finally, it is emphasized that the GVC improves vehicle dynamics performance as human-vehicle closed loop system by modifying driver’s operation.
Identifying clinical symptoms for improving the symptomatic diagnosis of chronic rhinosinusitis (2012)

The symptom-based diagnosis of CRS is challenging but symptoms of hyposmia is positively predictive while facial pain, a throbbing quality, headaches and photophobia are negatively predictive and show promise for improving the specificity of CRS diagnosis. Further validation studies are needed.
Demethoxycurcumin and its Semisynthetic Analogues as Antitubercular Agents (2008)

Demethoxycurcumin, isolated from the rhizomes of Curcuma longa, was found to possess antitubercular activity against Mycobacterium tuberculosis H (37)Rv strain at 200 microg/mL. Derivatisation of this active principle yielded a potent agent 6, exhibiting considerable activity with a minimum inhibitory concentration (MIC) value of 7.8 microg/mL. H (37)Rv:Mycobacterium tuberculosis H (37)Rv strain MIC:minimum inhibitory concentration.
Power Factor and Reactive Power in US Residences – Survey and EnergyPlus Modeling (2021)

Electric power systems are experiencing a growing number of electronic loads in the residential sector as modern appliance technology progresses, and it has become increasingly more important to consider the total power factor (PF) of residential communities. This paper provides a survey based on literature and publicly available information of typical appliance PF values and effects at the residential level as well as a discussion on appliance energy use and corresponding operation schedules. A procedure for the calculation of equivalent PF is proposed and exemplified with minutely experimental data at 15-minute and hourly time intervals, which correspond to smart metering and traditional practices, respectively. The application of the proposed equivalent PF procedure in coordination with building energy modeling, may, in principle, be employed to determine PF for entire communities at an aggregated level. The paper includes a proposal to simulate reactive power through an approach that utilizes EnergyPlus, a building energy modeling software. Such simulation capability could facilitate improved planning for compensation implementation both in electric power distribution networks and in individual residences, which offers significant opportunity for energy savings.
Performance of Non-orthogonal Multiple Access with SIC in Cellular Downlink Using Proportional Fair-Based Resource Allocation (2015)

This paper investigates the system-level throughput of non-orthogonal multiple access (NOMA) with a successive interference canceller (SIC) in the cellular downlink assuming proportional fair (PF)-based radio resource (bandwidth and transmission power) allocation. The purpose of this study is to examine the possibility of applying NOMA with a SIC to the systems beyond the 4G cellular system. Both the mean and cell-edge user throughput are important in a real system. PF-based scheduling is known to achieve a good tradeoff between them by maximizing the product of the user throughput among users within a cell. In NOMA with a SIC, the scheduler allocates the same frequency to multiple users simultaneously, which necessitates multiuser scheduling. To achieve a better tradeoff between the mean and cell-edge user throughput, we propose and compare three power allocation strategies among users, which are jointly implemented with multiuser scheduling. Extensive simulation results show that NOMA with a SIC with a moderate number of non-orthogonally multiplexed users significantly enhances the system-level throughput performance compared to orthogonal multiple access (OMA), which is widely used in 3.9 and 4G mobile communication systems.

Reduction of GIDL Using Dual Work-Function Metal Gate in DRAM (2016)

A novel work-function modulation technique for dual work-function (WF) metal gate for DRAM access device is investigated to minimize the leakage current in the access transistor. Gate Induced Drain Leakage (GIDL) is believed to be the most dominant off state leakage from storage node junction. Due to high doping in access device storage node side, lateral electric field near the storage node increases, which enhance the GIDL. Increased GIDL in DRAM puts limits on further scaling of DRAM cell. In this paper GIDL current dependence on gate metal work function has been investigated with TCAD simulation. A solution is proposed to minimize the GIDL current as well as possible fabrication techniques.

In risk allele carriers, a defective response of USF1 to insulin results in the suboptimal response of relevant target genes that contributes to the enhanced risk of developing dyslipidemia and coronary heart disease.
The synthesis of poly(butylene terephthalate) from terephthalic acid, part II: Assessment of the first stage of the polymerization process (2009)

Abstract The production of poly(butylene terephthalate) (PBT) struggles with the formation of substantial amounts of tetrahydrofuran (THF). When PBT is synthesized from terephthalic acid (TPA) instead of dimethyl terephthalate (DMT), even more THF is formed, mainly during the first stage of the melt polymerization process. Although a lot of literature reports on the existence of this side reaction in both processes, to the best of our knowledge, a comparison, which reveals the importance of the acidity and insolubility of TPA on the THF formation, was never described. Finally, an interesting study was performed on the THF formation during the synthesis of PBT from mixtures of DMT and TPA as well as from the completely soluble monomethyl terephthalate (MMT). © 2009 Wiley Periodicals, Inc.

<title>NeTra-V: toward an object-based video representation</title> (1997)

There is a growing need for new representations of video that allow not only compact storage of data but also content-based functionalities such as search and manipulation of objects. We present here a prototype system, called NeTra-V, that is currently being developed to address some of these content related issues. The system has a two-stage video processing structure: a global feature extraction and clustering stage, and a local feature extraction and object-based representation stage. Key aspects of the system include a new spatio-temporal segmentation and object-tracking scheme, and a hierarchical object-based video representation model. The spatio-temporal segmentation scheme combines the color/texture image segmentation and affine motion estimation techniques. Experimental results show that the proposed approach can handle large motion. The output of the segmentation, the alpha plane as it is referred to in the MPEG-4 terminology, can be used to compute local image properties. This local information forms the low-level content description module in our video representation. Experimental results illustrating spatio- temporal segmentation and tracking are provided.
The earlier the better: instantaneous cutaneous concentration quantification at the time of application (2022)

Cutaneous pharmacokinetics (cPK) can be quantified utilizing a myriad of in vitro and in vivo approaches. However, these techniques provide macroscale cPK for long experimental durations and do not provide cPK information from the moments directly after a topical formulation application, thus missing critical product dosing insight. Furthermore, formulations are typically applied for 5-10 minutes in the clinic and then removed (purposely or accidentally), which requires a high temporal and spatial resolution estimate of the early timepoint cPK. We have developed a 3-D printed applicator to address the unmet need for early time-point cPK quantification pertinent to the clinic.
Why Are Only Some Basal Plane Dislocations Converted to Threading Edge Dislocations During SiC Epitaxy? (2006)

This DOI is not currently attached to any metadata records. DOIs can’t actually ever be deleted (they’re persistent), but sometimes our members create DOIs in error. We do have a process to approximate deletion which we follow only in rare cases where the DOI has been genuinely created in error, and most crucially, if the DOI has never been published anywhere online or in print and never otherwise distributed to or communicated with anyone (authors, readers, reviewers, etc.
Real-time Spectral Filtering and Interferometric Spectral Phase Compensation in a Feedback Fiberized High Power Chirped Pulse Amplification System (2013)

Parabolic spectral filtering and interferometric spectral phase compensation was implemented in a real-time feedback loop for high power fiber CPA system, resulting in near transform limited sub-picosecond pulses and 4.5 times increase in peak power.
Performance Analysis of Time-Critical Peer-to-Peer Communications in IEEE 802.15.4 Networks (2011)

Existing works on the performance analysis of IEEE 802.15.4 networks with peer-to-peer (P2P) topologies assume the non-beacon unslotted mode in the MAC layer, which is not suitable for time-critical communications required by many applications, such as control, actuation and monitoring applications. In this paper, we introduce an enhanced guaranteed time slot (GTS) mechanism which can support time-critical P2P communications in wireless sensor networks (WSNs). An efficient Markov chain that takes into account retransmission limits, acknowledgements, unsaturated traffic and packet delivery ratios of links is proposed to model P2P communications using this enhanced GTS mechanism. Based on this model, we analyze the expected reliability and energy consumptions under various traffic conditions. In addition, the impact of MAC parameters on these performance indexes is analyzed. Monte Carlo simulations show that our theoretical analysis is quite accurate, and thus can be used as guidance for networks configuration in WSNs.
