Scutellarin inhibits the uninduced and metal-induced aggregation of α-Synuclein and disaggregates preformed fibrils: implications for Parkinson's disease
Authors: Zaidi Fatima Kamal , Deep Shashank
Published: January 2020

The aggregation of the protein alpha synuclein (α-Syn), a known contributor in Parkinson's disease (PD) pathogenesis is triggered by transition metal ions through occupational exposure and disrupted metal ion homeostasis. Naturally occurring small molecules such as polyphenols have emerged as promising inhibitors of α-Syn fibrillation and toxicity and could be potential therapeutic agents against PD. Here, using an array of biophysical tools combined with cellular assays, we demonstrate that the novel polyphenolic compound scutellarin efficiently inhibits the uninduced and metal-induced fibrillation of α-Syn by acting at the nucleation stage and stabilizes a partially folded intermediate of α-Syn to form SDS-resistant, higher-order oligomers (∼680 kDa) and also disaggregates preformed fibrils of α-Syn into similar type of higher-order oligomers. ANS binding assay, fluorescence lifetime measurements and cell-toxicity experiments reveal scutellarin-generated oligomers as compact, low hydrophobicity structures with modulated surface properties and significantly reduced cytotoxicity than the fibrillation intermediates of α-Syn control. Fluorescence spectroscopy and isothermal titration calorimetry establish the binding between scutellarin and α-Syn to be non-covalent in nature and of moderate affinity (Ka ∼ 105 M−1). Molecular docking approaches suggest binding of scutellarin to the residues present in the NAC region and C-terminus of monomeric α-Syn and the C-terminal residues of fibrillar α-Syn, demonstrating inhibition of fibrillation upon binding to these residues and possible stabilization of the autoinhibitory conformation of α-Syn. These findings reveal interesting insights into the mechanism of scutellarin action and establish it as an efficient modulator of uninduced as well as metal-induced α-Syn fibrillation and toxicity.
Contributions to Speech-Cue Weighting in Older Adults With Impaired Hearing
Authors: Souza Pamela , Gallun Frederick , Wright Richard
Published: January 2020

Purpose

In a previous paper (Souza, Wright, Blackburn, Tatman, & Gallun, 2015), we explored the extent to which individuals with sensorineural hearing loss used different cues for speech identification when multiple cues were available. Specifically, some listeners placed the greatest weight on spectral cues (spectral shape and/or formant transition), whereas others relied on the temporal envelope. In the current study, we aimed to determine whether listeners who relied on temporal envelope did so because they were unable to discriminate the formant information at a level sufficient to use it for identification and the extent to which a brief discrimination test could predict cue weighting patterns.

Method

Participants were 30 older adults with bilateral sensorineural hearing loss. The first task was to label synthetic speech tokens based on the combined percept of temporal envelope rise time and formant transitions. An individual profile was derived from linear discriminant analysis of the identification responses. The second task was to discriminate differences in either temporal envelope rise time or formant transitions. The third task was to discriminate spectrotemporal modulation in a nonspeech stimulus.

Results

All listeners were able to discriminate temporal envelope rise time at levels sufficient for the identification task. There was wide variability in the ability to discriminate formant transitions, and that ability predicted approximately one third of the variance in the identification task. There was no relationship between performance in the identification task and either amount of hearing loss or ability to discriminate nonspeech spectrotemporal modulation.

Conclusions

The data suggest that listeners who rely to a greater extent on temporal cues lack the ability to discriminate fine-grained spectral information. The fact that the amount of hearing loss was not associated with the cue profile underscores the need to characterize individual abilities in a more nuanced way than can be captured by the pure-tone audiogram.
Very‐large‐scale integration implementation of a convolutional neural network accelerator for abnormal heartbeat detection
Authors: Chen Y.‐H. , Juan Y.
Published: January 2020

In this study, a very‐large‐scale integration implementation of a convolutional neural network (CNN) inference for abnormal heartbeat detection was proposed. Four‐lead electrocardiogram signals were used to detect abnormal heartbeat conditions, such as premature ventricular complex. 1D CNNs and fully connected layers were utilised in the proposed chip to achieve high‐speed, small‐area, and high‐accuracy arrhythmia detection. The proposed chip was implemented using a 90‐nm complementary metal‐oxide‐semiconductor process and operated at 125 MHz with a core area. The power consumption was at high‐speed operation frequency (125 MHz) and at for low‐power applications. The detection accuracy was based on the MIT‐BIH arrhythmia database. Consequently, the properties of high speed, low power, small area, and high accuracy were established in the proposed accelerator chip.
Waveguide measurements of biochar derived from sewage sludge
Authors: Savi P. , Yasir M.
Published: January 2020

Composites based on biochar derived from sewage sludge as filler in epoxy resin are fabricated and measured in a waveguide in C‐band. Biochar is cheap, readily available and environmentally friendly and thus is a very good contender among other carbon‐based materials for use in shielding applications. Biochar provide promising results in term of transmission of <−10 dB for a composite with 20 wt.% biochar filler. The dissipation loss, calculated from the scattering parameters show that a significant portion of the losses are due to dissipation.

Deep learning architecture for direct probability density prediction of small‐scale solar generation
Authors: Afrasiabi Mousa , Mohammadi Mohammad , Rastegar Mohammad , Afrasiabi Shahabodin
Published: January 2020

With the increasing penetration of photovoltaic (PV) systems, the problems posed by the inherent intermittency of small‐scale PVs are becoming more severe. To address this issue, it is critical to involve the uncertainty of PV generation in the look‐ahead periods in a comprehensive framework. To this end, a direct deep learning architecture for probabilistic forecasting of solar generation is proposed in this paper. An end‐to‐end deep learning architecture as a novel mixture density network (MDN) is designed based on the combination of a convolutional neural network and a gated recurrent unit. Furthermore, a new loss function and training process based on adversarial training is proposed to enhance the accuracy in direct contracting of the probability density function. Then, several deep and shallow networks are implemented, and the results are compared with the proposed architecture. The effectiveness of the proposed MDN in providing complete statistical information is verified through comparison with Monte Carlo dropout, non‐parametric kernel density estimation, and the proposed MDN without adversarial training.
Analysis and design of compact four‐way single‐ and dual‐band filtering power dividers on a new adjustable multi‐mode topology
Authors: Zhang Gang , Zhang Xinde , Qian Zhenyao , Yang Jiquan
Published: January 2020

Four‐way single‐/dual‐band operation integrated filtering power divider (FPD) with new design topology is presented in this study. For either single‐ or dual‐passband response, it involves only one same‐type pair of multi‐mode resonators and three isolation resistors, comparing with other existing four‐way FPDs. By adopting the even‐/odd‐mode analysis method to flexibly control the resonant modes of the designed resonator and select isolation resistances, both single‐ and dual‐band four‐way filtering power division responses are specified and derived with the same one configuration. The proposed four‐way FPD designs stand out from the reported ones by both nice operation performance, flexible topology with reduced number of resonators, and no additional feeding network at input port. For demonstration, two prototypes for four‐way single‐ and dual‐band FPDs are implemented following the given design procedure, respectively. Both simulated and measured results are exhibited to verify the theoretical design concept.
Framework of locality electricity trading system for profitable peer‐to‐peer power transaction in locality electricity market
Authors: Rao Bokkisam Hanumantha , Arun Saravana Loganathan , Selvan Manickavasagam Parvathy
Published: January 2020

This paper proposes an architecture of locality electricity market (LEM) for peer‐to‐peer (P2P) energy trading among a group of residential prosumers (consumers and producers) with renewable energy resources, smart meters, information and communication technologies, and home energy management systems in a smart residential locality. Prosumers may sell(buy) their excess generation(demand) in LEM at a profitable prices compared to the utility prices in P2P fashion. In order to manage the trading in LEM, a common portal named as locality electricity trading system (LETS) is introduced. The purpose of LETS is to prepare a trading agreement between the participants by fixing a price for every deal based on the quoted price and day‐ahead power trading schedule given by the participants. An enhanced intelligent residential energy management system (EIREMS) is proposed at the prosumers' premises to enable their participation in the day‐ahead energy trading process and in real‐time scheduling of schedulable loads and battery for reducing the electricity bill with due consideration to the operational constraints and LETS agreement. The performances of proposed LETS and EIREMS are validated through a few case studies on a locality with ten prosumers. The proposed methodology endorses marginal economic benefit for all the participants.
Adapting big data standards, maturity models to smart grid distributed generation: critical review
Authors: Sundararajan Aditya , Hernandez Alexander S. , Sarwat Arif I.
Published: January 2020

Big data standards and capability maturity models (CMMs) help developers build applications with reduced coupling and increased breadth of deployment. In smart grids, stakeholders currently work with data management techniques that are unique and customised to their own goals, thereby posing challenges for grid‐wide integration and deployment. Although big data standards and CMMs exist for other domains, no work in the literature considers adapting them to smart grids, which will benefit from both. Further, existing smart grid standards and CMMs do not fully account for big data challenges. This study bridges the gap by analysing the role of big data in smart grids, and explores if and how big data standards and CMMs can be adapted specifically to ten distributed generation (DG) use‐cases that use big data. In doing so, this work provides a useful starting point for researchers and industry members developing standards and CMM assessments for smart grid DG.
RASCAS: RAdiation SCattering in Astrophysical Simulations
Authors: Michel-Dansac L. , Blaizot J. , Garel T. , Verhamme A. , Kimm T. , Trebitsch M.
Published: January 2020

Context. Resonant lines are powerful probes of the interstellar and circumgalactic medium of galaxies. Their transfer in gas being a complex process, the interpretation of their observational signatures, either in absorption or in emission, is often not straightforward. Numerical radiative transfer simulations are needed to accurately describe the travel of resonant line photons in real and in frequency space, and to produce realistic mock observations.

Aims. This paper introduces RASCAS, a new public 3D radiative transfer code developed to perform the propagation of any resonant line in numerical simulations of astrophysical objects. RASCAS was designed to be easily customisable and to process simulations of arbitrarily large sizes on large supercomputers.

Methods. RASCAS performs radiative transfer on an adaptive mesh with an octree structure using the Monte Carlo technique. RASCAS features full MPI parallelisation, domain decomposition, adaptive load-balancing, and a standard peeling algorithm to construct mock observations. The radiative transport of resonant line photons through different mixes of species (e.g. H I, Si II, Mg II, Fe II), including their interaction with dust, is implemented in a modular fashion to allow new transitions to be easily added to the code.

Results. RASCAS is very accurate and efficient. It shows perfect scaling up to a minimum of a thousand cores. It has been fully tested against radiative transfer problems with analytic solutions and against various test cases proposed in the literature. Although it was designed to describe accurately the many scatterings of line photons, RASCAS may also be used to propagate photons at any wavelength (e.g. stellar continuum or fluorescent lines), or to cast millions of rays to integrate the optical depths of ionising photons, making it highly versatile.
What determines the formation and characteristics of protoplanetary discs?
Authors: Hennebelle Patrick , Commerçon Benoit , Lee Yueh-Ning , Charnoz Sébastien
Published: January 2020

Context. Planets form in protoplanetary discs. Their masses, distribution, and orbits sensitively depend on the structure of the protoplanetary discs. However, what sets the initial structure of the discs in terms of mass, radius and accretion rate is still unknown.

Aims. It is therefore of great importance to understand exactly how protoplanetary discs form and what determines their physical properties. We aim to quantify the role of the initial dense core magnetisation, rotation, turbulence, and misalignment between rotation and magnetic field axis as well as the role of the accretion scheme onto the central object.

Methods. We performed non-ideal magnetohydrodynamics numerical simulations using the adaptive mesh refinement code Ramses of a collapsing, one solar mass molecular core to study the disc formation and early, up to 100 kyr, evolution. We paid particular attention to the impact of numerical resolution and accretion scheme.

Results. We found that the mass of the central object is almost independent of the numerical parameters such as the resolution and the accretion scheme onto the sink particle. The disc mass and to a lower extent its size, however heavily depend on the accretion scheme, which we found is itself resolution dependent. This implies that the accretion onto the star and through the disc are largely decoupled. For a relatively large domain of initial conditions (except at low magnetisation), we found that the properties of the disc do not change too significantly. In particular both the level of initial rotation and turbulence do not influence the disc properties provide the core is sufficiently magnetised. After a short relaxation phase, the disc settles in a stationary state. It then slowly grows in size but not in mass. The disc itself is weakly magnetised but its immediate surrounding on the contrary is highly magnetised.

Conclusions. Our results show that the disc properties directly depend on the inner boundary condition, i.e. the accretion scheme onto the central object. This suggests that the disc mass is eventually controlled by a small-scale accretion process, possibly the star-disc interaction. Because of ambipolar diffusion and its significant resistivity, the disc diversity remains limited and except for low magnetisation, their properties are weakly sensitive to initial conditions such as rotation and turbulence.
Numerical analysis of sparse initial data identification for parabolic problems
Authors: Leykekhman Dmitriy , Vexler Boris , Walter Daniel
Published: January 2020

In this paper we consider a problem of initial data identification from the final time observation for homogeneous parabolic problems. It is well-known that such problems are exponentially ill-posed due to the strong smoothing property of parabolic equations. We are interested in a situation when the initial data we intend to recover is known to be sparse, i.e. its support has Lebesgue measure zero. We formulate the problem as an optimal control problem and incorporate the information on the sparsity of the unknown initial data into the structure of the objective functional. In particular, we are looking for the control variable in the space of regular Borel measures and use the corresponding norm as a regularization term in the objective functional. This leads to a convex but non-smooth optimization problem. For the discretization we use continuous piecewise linear finite elements in space and discontinuous Galerkin finite elements of arbitrary degree in time. For the general case we establish error estimates for the state variable. Under a certain structural assumption, we show that the control variable consists of a finite linear combination of Dirac measures. For this case we obtain error estimates for the locations of Dirac measures as well as for the corresponding coefficients. The key to the numerical analysis are the sharp smoothing type pointwise finite element error estimates for homogeneous parabolic problems, which are of independent interest. Moreover, we discuss an efficient algorithmic approach to the problem and show several numerical experiments illustrating our theoretical results.
Perception of plastic surgery in the society
Authors: Agarwal Pawan
Published: January 2020

The perception of plastic surgery in society is limited and underestimates the versatility of the specialty. A survey was conducted in order to assess knowledge and to provide some initial evidence for education about the scope of plastic surgery amongst the public, medical and nursing students and general practitioners. A questionnaire was devised and four population groups of respondents were surveyed at random in one district. The results reveal that the majority of the public needs more information about the benefits that our specialty can offer them. Plastic surgeons are mainly associated with burns and cosmetic surgery and they are not necessarily identified as primary surgeons for procedures fundamental to our specialty. If patients are to receive the best treatment available, it is essential that we educate the public about our clinical interests and activities.
Different levels of undermining in face lift - experience of 141 consecutive cases
Authors: Panettiere Pietro , Marchetti Lucio , Accorsi Danilo , Del Gaudio Giovanni-Alberto
Published: January 2020

CONTEXT: The most revolutionary concept in rhytidectomy is the role of Sub Muscular Aponeurotic System (SMAS), even if many alternative approaches have been proposed. The main aim of face lift is to bring back the time, preventing the "lifted-face" appearance. SETTINGS AND DESIGN: The authors present their personal experience with different levels of undermining, i.e. subperiosteal forehead lift, subcutaneous midface lift with SMAS plication and platysmal suspension, and discuss the anatomical and biomechanical elements of rhytidectomy. RESULTS: Optimal aesthetic results were achieved by repositioning the neck, face and forehead tissues in a global and harmonious fashion, without distorting face characteristics and disguising surgery trails as much as possible. CONCLUSIONS: Different levels of undermining can give good and stable aesthetic results minimizing the risks and preventing face distortion.

CONTEXT: Anthrax is a very rare disease in Europe and the United States. AIM: A case of cutaneous anthrax of the hand with a wide skin defect is presented and some clinical observations highlighted. CASE REPORT: A 56-year-old male patient with cutaneous anthrax attended our infectious diseases department with a swelling up to the upper arm. An urgent fasciotomy was undertaken with a diagnosis of compartment syndrome. A black eschar had formed on the dorsal surface of the hand. A superficial tangential escharectomy was performed. RESULTS: Viable fibrous tissue, about 4 to 5 mm in thickness over the extensor tendons, was found under the eschar. At the postoperative 2-year follow-up, remarkable healing was observed via skin grafting. CONCLUSIONS: Hand surgeons should be cautious against the compartment syndrome that may accompany cutaneous anthrax of the hand. A consistent viable fibrous tissue can be found below the eschar. The mechanism for the involvement of the hand dorsum needs further concern.

Published: January 2020

Introduction Local anesthesia with sedation has been employed for an increasingly number of otolaryngology procedures, and might be associated with lower surgical morbidity and costs. Facial nerve monitoring is often advisable in otology to minimize the risks of injuries to this cranial nerve, but the principles, techniques and parameters involved have only been studied for procedures under general anesthesia.

Objective To report the preliminary outcomes of intraoperative facial nerve monitoring during otologic procedures under sedation and local anesthesia.

Methods A total of five procedures and their respective intraoperative electrophysiological main findings were described. Facial neuromonitoring was performed using the same device by an electrophysiologist. The monitor sensitivity was set at 100 mV, and a stimulating probe was used whenever needed.

Results Progressively decreasing low-amplitude baseline values were usually obtained as the level of anesthesia increased, with isolated oscillations possibly related to some degree of voluntary muscular activity. These oscillations could be easily distinguished from those of the surgical manipulation or electrical stimulation of the nerve, which tended to be of much greater amplitude and shorter latency, occurring during specific surgical steps.

Conclusion With a surgical team with proper procedural knowledge and broad expertise regarding the technique, intraoperative facial nerve monitoring under local anesthesia with sedation seemed both feasible and reliable. Thus, the need for intraoperative neuromonitoring should not be an obstacle for otologic procedures under less aggressive anesthetic management.

Introduction The clinical relevance of the anatomy and variations of the anterior ethmoidal artery (AEA) is outstanding, considering its role as a landmark in endoscopic surgery, its importance in the therapy of epistaxis, and the high risks related to iatrogenic injuries.

Objective To provide an anatomical description of the course and relationships of the AEA, based on direct computed-tomography (CT)-based 3D volume rendering.

Methods Direct volume rendering was performed on 18 subjects who underwent (CT) with contrast medium for suspected cerebral aneurism.

Results The topographical location of 36 AEAs was assessed as shown: 10 dehiscent (27.8%), 20 intracanal (55.5%), 6 incomplete canals (16.7%). Distances from important topographic landmarks are reported.

Conclusion This work demonstrates that direct 3D volume rendering is a valid imaging technique for a detailed description of the anterior ethmoidal artery thus representing a useful tool for head pre-operatory assessments.

Fireworks are commonly used in celebrate festive occasions. We present a case of an unusual presentation of intraoral firework injury, which is a very rare case. A fifteen year old boy kept four explosive papercaps wrapped in a small polythene bags in between his left molars and crushed them. This resulted in a contused lacerated wound over the left buccal mucosa. Patient was treated conservatively with maintenance of intraoral hygiene, antibiotics, proteolytic enzymes and analgesics. It took 18 days for complete healing of the wound.
Ischaemic contracture of the hand
Authors: Balakrishnan G.
Published: January 2020

Stronger flexor tendon repairs facilitate early active motion therapy protocols. Core sutures using looped suture material provide 1 ½ to twice the strength of Kessler′s technique (with four strand and six strand Tsuge technique respectively). The technique is well-described and uses preformed looped sutures (supramid). This is not available in many countries and we describe a technique whereby looped sutures can be introduced in flexor tendon repair by the use of 23 G hypodermic needle and conventional 4.0 or 5.0 sutures. This is an alternative when the custom made preformed sutures are not available. This can be practiced in zone 3 to zone 5 repairs. Technical difficulties limit its use in zone 2 repairs.
Medial circumflex femoral artery flap for ischial pressure sore
Authors: Palanivelu S.
Published: January 2020

A new axial pattern flap based on the terminal branches of the medial circumflex femoral artery is described for coverage of ischial pressure sore. Based on the terminal branches of the transverse branch of medial circumflex femoral artery, which exit through the gap between the quadratus femoris muscle above and the upper border of adductor magnus muscle below, this fascio cutaneous flap is much smaller than the posterior thigh flap but extremely useful to cover ischeal pressure sores. The skin redundancy below the gluteal fold allows a primary closure of the donor defect. It can also be used in combination with biceps femoris muscle flap.
Alveolar bone grafting
Authors: Lilja Jan
Published: January 2020

In patients with cleft lip and palate, bone grafting in the mixed dentition in the residual alveolar cleft has become a well-established procedure. The main advantages can be summarised as follows: stabilisation of the maxillary arch; facilitation of eruption of the canine and sometimes facilitation of the lateral incisor eruption; providing bony support to the teeth adjacent to the cleft; raising the alar base of the nose; facilitation of closure of an oro-nasal fistula; making it possible to insert a titanium fixture in the grafted site and to obtain favourable periodontal conditions of the teeth within and adjacent to the cleft. The timing of the ABG surgery take into consideration not only eruption of the canine but also that of the lateral incisor, if present. The best time for bone grafting surgery is when a thin shell of bone still covers the soon erupting lateral incisor or canine tooth close to the cleft.

Primary rhinoplasty: An Indian perspective
Authors: Uday Bhat , Bharat Patel
Published: January 2020

The spectrum of indications for rhinoplasty in Indian patients is very wide. An ill-defined nose with lack of projection and broad osteocartilagenous framework is the commonest problem. A large number of patients require narrowing of the framework by osteotomies, alar wedge resection,and augmentation by a suitable fill, preferably a cartilage graft. The technique of rhinoplasty in Indian patients with special emphasis on cartilage grafting has been discussed here. Cartilage grafts, when used as a fill, produce soft, natural results.

Published: January 2020

A high-throughput, operando-ready X-ray absorption spectroscopy catalytic reaction cell consisting of 4 parallel reactors was designed to collect X-ray absorption near edge structure and extended fine structure spectra under reaction conditions. The cell is capable of operating at temperatures from ambient conditions up to 773 K and pressures from ambient to 2 MPa in a variety of gas environments. The cell design is mechanically simple, and programmable operation at beamline 8-ID (NSLS-II, Brookhaven National Laboratory) makes it straightforward to use. Reactor tube parts were available as-fabricated from commercial sources, while the heating jacket and cell mounting required custom machining.
Fire behaviour in wheat crops – effect of fuel structure on rate of fire spread
Authors: Cruz Miguel G. , Hurley Richard J. , Bessell Rachel , Sullivan Andrew L.
Published: January 2020

A field-based experimental study was conducted in 50×50m square plots to investigate the behaviour of free-spreading fires in wheat to quantify the effect of crop condition (i.e. harvested, unharvested and harvested and baled) on the propagation rate of fires and their associated flame characteristics, and to evaluate the adequacy of existing operational prediction models used in these fuel types. The dataset of 45 fires ranged from 2.4 to 10.2kmh−1 in their forward rate of fire spread and 3860 and 28000 kWm−1 in fireline intensity. Rate of fire spread and flame heights differed significantly between crop conditions, with the unharvested condition yielding the fastest spreading fires and tallest flames and the baled condition having the slowest moving fires and lowest flames. Rate of fire spread in the three crop conditions corresponded directly with the outputs from the models of Cheney et al. (1998) for grass fires: unharvested wheat → natural grass; harvested wheat (~0.3m tall stubble) → grazed or cut grass; and baled wheat (<0.1m tall stubble) → eaten-out grass. These models produced mean absolute percent errors between 21% and 25% with reduced bias, a result on par with the most accurate published fire spread model evaluations.
