Image processing software for seizure onset zone localization in drug-resistant epilepsy

Epilepsy is one of the most common serious neurological disorders in the world and a 30-40% of the affected population is resistant to the pharmacological treatment (refractory epilepsy). A possible treatment for them is the surgical resection of the epileptogenic zone (EZ). The success of the surgical treatment is fundamentally determined by the accuracy of presurgical identification of the EZ based on a variety of diagnostic tests. Among them, PISCOM technique is a multimodal imaging processing algorithm, useful for this purpose, yet not incorporated into clinical routine. This project aims to develop an ergonomic and user-friendly graphical interface that integrates the PISCOM algorithm to make the process become easy and accessible for clinicians. To create the graphical interface, different software environments were studied. The solution chosen was to develop an extension for 3D Slicer, an open-source software package used for medical and biomedical imaging research, and the processing method was therefore adapted to the new platform. The result was assessed with a clinic questionnaire filled out by two nuclear medicine physicians of Hospital Clínic de Barcelona after an introduction session of the developed extension. The extension was considered to be a user-friendly tool for applying the PISCOM technique, that fulfilled their requirements, and with future potential. Some next steps to improve the user experience were suggested. Taking everything into account, the extension could substitute other tools for supporting seizure onset zone localization that require more image acquisitions, reducing the radiation over the patient and the cost of the diagnosis.

INFLUENCE OF DIAGENETIC DEPOSITS ON THE POROSITY OF SANDSTONES FROM IBOREPI FORMATION, LAVRAS DA MANGABEIRA BASIN

The study of diagenetic processes is essential to evaluate the potential of sandstones as good reservoirs of oil, gas, and water. Nonetheless, the diagenesis of the Iborepi Formation sandstones (Lavras da Mangabeira Basin) is little known, mainly regarding its effect on the original porosity of these rocks, which can be studied as analogs of oil basin reservoirs. Aiming to evaluate the diagenetic process that affected the Iborepi sandstones, as well as their potential for fluid storage, nine thin sections were analyzed. The study revealed that the processes that most affected the primary porosity of these rocks and their quality as reservoirs include compaction, cementation, and clay infiltration, with compaction prevailing. These processes have damaged the porosity and permeability of these rocks by reducing pore space and clogging pore throats. The detritic composition has also affected the original porosity, favoring some diagenetic processes. Although these rocks have a reasonable porosity for fluid storage (14% average), their diagenetic heterogeneities have impacted their quality as reservoirs.

A Study of Work Related Musculoskeletal Disorders By Using Rula and Reba Among the Workers Working in A Card-Board Industry

India is a developing country and Musculoskeletal disorders (MSDs) are common problem in Indian indus- tries. In Indian card-board industries we find MSDs is high i.e. the exposure of worker to MSD risk is high. All work is done manually by the workers. Most workers are male. The manual work load can therefore cause MSDs amongst the workers. In this paper the MSDs are observed by ergonomic body posture analysis tools. Body postural analysis using RULA, REBA indicates that the workers are working above the safe limit. Which tells us that the body posture in not safe, need investigation and change.
Air quality observations onboard commercial and targeted Zeppelin flights in Germany – a platform for high-resolution trace-gas and aerosol measurements within the planetary boundary layer

Abstract. A Zeppelin airship was used as a platform for in-situ measurements of greenhouse gases and short-lived air pollutants within the planetary boundary layer in Germany. A novel quantum cascade laser-based multi-compound gas analyzer (MIRO Analytical AG) was deployed to simultaneously measure in-situ concentrations of greenhouse gases (CO2, N2O, H2O, and CH4) and air pollutants (CO, NO, NO2, O3, SO2, and NH3) with high precision at a measurement rate of 1 Hz. These measurements were complemented by electrochemical sensors for NO, NO2, Ox (NO2+O3), and CO, an optical particle counter, temperature, humidity, altitude, and position monitoring. Instruments were operated remotely without the need for on-site interactions. Three two-week campaigns were conducted in 2020 comprising commercial passenger as well as targeted flights over multiple German cities including Cologne, Mönchengladbach, Düsseldorf, Aachen, Frankfurt, but also over industrial areas and highways. Vertical profiles of trace gases were obtained during the airship landing and take-off. Diurnal variability of the Zeppelin vertical profiles was compared to measurements from ground-based monitoring stations with a focus on nitrogen oxides and ozone. We find that their variability can be explained by the increasing nocturnal boundary layer height from early morning towards midday, an increase in emissions during rush hour traffic, and the rapid photochemical activity midday. Higher altitude (250–450 m) NOX to CO ratios are further compared to the 2015 EDGAR emission inventory to find that pollutant concentrations are influenced by transportation and residential emissions as well as manufacturing industries and construction activity. Finally, we report NOx and CO concentrations from one plume transect originating from a coal power plant and compare it to the EURAD-IM model to find agreement within 15 %. However, due to the increased contribution of solar and wind energy and/or the impact of lockdown measures the power plant was operated at max. 50 % capacity; therefore, possible overestimation of emissions by the model cannot be excluded.
Transient Process of Rotating Stall in Radial Vaneless Diffusers

This paper describes the process of rotating stall inception in a radial vaneless diffuser. Unsteady flow and rotating stall were investigated by measuring the wall static pressures and velocity distributions using X hot-wire probe. From the measurements of the velocity fluctuation, it is confirmed that the periodical disturbance in the reverse flow region as the prestall symptom occurs prior to the onset of stall and then the growth of that periodical disturbance leads to the rotating stall with fully developed non axisymmetric reversed flow. On the process of the rotating stall inception, reverse flow regions in the diffuser grow from the diffuser exit toward the inlet along the shroud and hub wall, and the rotating stall occurs when the reverse flow region on the shroud wall reaches to the impeller exit. In this paper, the effects of the diffuser exit blockage on the process of stall inception were also described. The flow rate of stall onset is moved to the lower side by the restriction of the diffuser exit width, however, this restriction does not affect the distribution of the reverse flow regions. That restriction suppresses the prestall disturbance in the reverse flow regions and then stabilize the flow in the diffuser.Copyright © 1994 by ASME
Influence of the Si/SiO 2 interface on the charge carrier density of Si nanowires

The electrical properties of Si nanowires covered by aS iO 2 shell are influenced by the properties of the Si/SiO2 in- terface. This interface can be characterized by the fixed oxide charge density Qf and the interface trap level density Dit . W e derive expressions for the effective charge carrier density in sil- icon nanowires as a function of Qf, Dit, the nanowire radius, and the dopant density. It is found that a nanowire is fully depleted when its radius is smaller than a critical radius acrit. An analytic expression for acrit is derived.

ROBOTIC AUGMENTATION OF EVA FOR HUBBLE SPACE TELESCOPE SERVICING

The University of Maryland Space Systems Laboratory has developed the Ranger Telerobotic Shuttle Experiment, which was intended to be an initial flight demonstration of dexterous robotics for space operations. Ranger TSX incorporates advanced robotic manipulators capable of using EVA interfaces and performing EVA tasks, and was intended for a space shuttle test flight in 2004 prior to recent programmatic cutbacks. To better quantify the impact of Ranger-level dexterous robotics on space operations, Hubble Space Telescope servicing was adopted as a set of reference missions. This was a logical decision, since Ranger was designed to be as capable as an astronaut in extravehicular activity (EVA), and several of the Ranger experimental tasks were directly taken from HST servicing experience. HST EVA operations from the first four servicing missions were broken down into tasks, subtasks, and primitives, and were evaluated for telerobotic operations. For each candidate, the primitives were quantified in terms of what percentage could be performed by a robot, and whether robotic operations were best performed before, during, or after the EVA operations. Initial resulted indicated that, for the first servicing mission, a single robotic assistant for the EVA crew would increase productivity by 60%. This would allow the five EVAs of SM-1 to be performed in three, or would allow the equivalent of three more EVA-only operational days to be included in five EVA sorties for the human/robot team activities. Further analysis of later missions, which had fewer contingency operations, showed that up to 80% of the EVA tasks could have been reassigned to the robot. This paper presents the results of this analysis, along with further research into specific interfaces required for telerobotic operations, and more global redesign of mission operations to optimize performance of the human/robotic teams.
Particle Swarm Optimisation Based Feedback Controller Design for Induction Motor Soft-Startingd

Abstract The objective of this work is to design and implement a closed loop system for induction motor starting at rated current. Thyristorised AC voltage regulator is used as the starting equipment and motor current regulation is carried out using an optimally tuned proportionalintegral (PI) controller. Since AC voltage controller fed starting of induction motor is a non-linear process, identification of optimal values of PI controller constants is performed using particle swarm optimisation. The complete drive system including AC voltage controller fed induction motor in conjunction with optimal PI controller is first simulated in MATLAB and subsequently verified experimentally. The successful implementation with a low cost microcontroller illustrates the feasibility of the new approach.
Time stability of asymmetric Fabry-Perot modulator-based analog lightwave links

Lightwave links for analog signal transfer are being developed and evaluated for application in high-density interconnects. The reflective links are based on compact electrooptic intensity modulators connected by ribbons of single-mode fibers to remotely located transceivers (lasers and photoreceivers) and read-out electronics. For long term characterization, four asymmetric Fabry-Perot modulator (AFPM) prototypes have been continuously operated and monitored during a period of eight months. The collected data allow evaluation of the system time stability and simulation of the possible recalibration procedures. The recalibration requirements to achieve the desirable accuracy and reliability are inferred statistically.
Challenges to capturing expertise in field settings

This chapter proposes that to capture expertise in field settings sport scientists should base experimental designs on an inter-disciplinary theoretical foundation and utilise coach and athlete expertise to identify the key variables upon which to focus. We propose that an ecological dynamics framework may allow motor learning and performance to be examined in a more representative manner. After initially considering the problem from the view of a “new” skill acquisition scientist, we provide an overview of previous approaches, before providing theoretical and practically driven ideas to guide sport scientists’ practice going forward.
An analog sampled-data DSB to SSB converter using recursive Hilbert transformer for accurate I and Q channel matching

The realization of a complete double-sideband (DSB) to single-sideband (SSB) converter using switched-capacitor techniques is presented. The proposed approach employs a recursive Hilbert transformer to achieve efficient SSB modulation. The design of the Hilbert transformer through structurally all-pass networks allows good dynamic range and small sensitivity to capacitance ratio errors. The sampling rate of the output SSB signal is reduced by a factor of two, so that the Hilbert transformer and the following circuitry work at half of the input sampling rate, reducing circuit complexity and power consumption, without loss of information. Experimental laboratory results obtained with a prototype realization using discrete components are presented. Practical aspects pertaining to a monolithic implementation in complementary metal-oxide-semiconductor (CMOS) technology are considered.
Continuous Feature-Based Tracking of the Inner Ear for Robot-Assisted Microsurgery

Robotic systems for surgery of the inner ear must enable highly precise movement in relation to the patient. To allow for a suitable collaboration between surgeon and robot, these systems should not interrupt the surgical workflow and integrate well in existing processes. As the surgical microscope is a standard tool, present in almost every microsurgical intervention and due to it being in close proximity to the situs, it is predestined to be extended by assistive robotic systems. For instance, a microscope-mounted laser for ablation. As both, patient and microscope are subject to movements during surgery, a well-integrated robotic system must be able to comply with these movements. To solve the problem of on-line registration of an assistance system to the situs, the standard of care often utilizes marker-based technologies, which require markers being rigidly attached to the patient. This not only requires time for preparation but also increases invasiveness of the procedure and the line of sight of the tracking system may not be obstructed. This work aims at utilizing the existing imaging system for detection of relative movements between the surgical microscope and the patient. The resulting data allows for maintaining registration. Hereby, no artificial markers or landmarks are considered but an approach for feature-based tracking with respect to the surgical environment in otology is presented. The images for tracking are obtained by a two-dimensional RGB stream of a surgical microscope. Due to the bony structure of the surgical site, the recorded cochleostomy scene moves nearly rigidly. The goal of the tracking algorithm is to estimate motion only from the given image stream. After preprocessing, features are detected in two subsequent images and their affine transformation is computed by a random sample consensus (RANSAC) algorithm. The proposed method can provide movement feedback with up to 93.2 μm precision without the need for any additional hardware in the operating room or attachment of fiducials to the situs. In long term tracking, an accumulative error occurs.
LARGE-EDDY SIMULATION OF THE AERODYNAMIC PITCHING STABILITY OF ROAD VEHICLE

Aerodynamic pitching stability of sedan-type road vehicle was investigated using the Large-Eddy Simulation technique. The study was based on two kinds of simplified vehicle models, which represent two real sedan-type vehicles with different pitching stability at on-road tests. The simplified vehicle modes were developed to reproduce the characteristic flow structures above the trunk deck of the real vehicles. Both models were seemingly identical and only the difference was their front and rear pillars shape. The aerodynamic pitching stability characteristics were determined through the phase-averaged pitching moment acting on both models by imposing the forced sinusoidal pitching oscillation as input. Arbitrary Lagrangian-Eulerian method was adopted to capture the dynamic motion of the models. It was demonstrated that the model representing the flow structures of the more stable sedan vehicle showed higher aerodynamic damping than the model of the less stable vehicle. It was concluded that pitching stability of sedan-type road vehicle is associated with the aerodynamic pitching damping mechanism caused by flow structures above the trunk deck, and the structures are strongly affected by slight geometrical difference of front and rear pillars.

Amoebiasis is the third leading cause of death from parasitic disease worldwide. The causative protozoan parasite, Entamoeba histolytica, is a potent pathogen. Propolis is a natural resinous substance collected by bees from vegetable sources and it has a therapeutic properties have been investigated in this work. So we evaluated the inhibitory activity of ethanolic extracts of propolis (EEP) on Entamoeba histolytica trophozoite growth. Propolis inhibited the growth of E.histolytica trophozoites and the level of inhibition varied according to the extract concentration and incubation times, it also showed a marked activity on cell lysis of trophozoite. The highest reduction of parasite growth was observed in culture exposed to (25,50 mg/ml) of propolis, in all incubation periods (24,48 )h. Growth reduction by 76 % was observed in 12.5 mg/ml propolis-treated culture, while the concentrations of (25, 50) mg/ml were able to inhibit growth by more than 90%. Light microscopic study showed morphological changes in E.histolytica trophozoites. صلختسملا تلاوحتملا ءاد دعی ةیبیملأا ثلاث رثكأ ضارملإا ابیملاا يلیفط دعیو , ملاعلا يف اعویش ةتیمملا ةیلیفطلا ةلاحلا ضرملا اذھل يسیئرلا ببسملا جسنلل نم نوكتتو عمجت ةیعیبط ةیجنتار ةدام دعیف ربكعلل ةبسنلابو . و لحنلا ةطساوب ةیتابن رداصم دعی راوطلاا ىلع ربكعلل ةیطیبثتلا ةیلاعفلا ةسارد مت كلذل . ایجلاع اردصم ومن طیبثت يف ربكعلا ةیلاعف جئاتنلا ترھظأ . جاجزلا يف جسنلل ةلاحلا ابیملال ةیذغتملا راوطلأا ةیذغتملا يلیفطلل ةیذغتملا راوطلاا للحت ظحول امك ضرعتلا تقوو صلختسملا زیكرت ىلع دامتعلاابو امك ، ترھظأ ىلعأ ومنل طیبثت ةبسن راوطلأا زیكارتلا دنع يلیفطلل ةیذغتملا ) 25 , 50 ( صلختسملا نم ریتلیلم /مغلم تغلب ذأ ربكعلل يلوحكلا 90 زیكرتلا دنع امنیب ، % 12.5 ةلماعملا ةیلاعف تغلب دقف ریتلیلم/مغلم 76 لاًضف . % ابیملاا يلیفطل ةیلكش تاریغت ظحول دقف كلذ نع ةلاحلا لل . ربكعلل يلوحكلا صلختسملاب لماعملا جسن Introduction Amoebiasis is one of the major health problems in several developing countries; as a result amoebic dysentery is common in tropic and subtropics regions [1]. Secreting proteinases that dissolve host tissues, killing host cells on contact, and engulfing red blood cells, E histolytica trophozoites invade the intestinal mucosa; causing amoebic colitis is acquired by ingestion of Entamoeba histolytica cysts [2]. Although cysts are the infective stage, have not been induced in vitro, due to the absence of a medium or method that supports the in vitro mass encystation of this species [3]. This has been a barrier to research to control methods for this phase of E. histolytica life cycle. Metronidazole is known to be highly effective amoebicide and is considered to be the drug of choice for the treating amoebiasis, but this drug has been found to possess
A Survey of Privacy Concerns in Blockchains and Information Retrieval

With the increase in population the number of internet users has also increased over the years, protecting the privacy of user data has become an important issue. To maintain the privacy of ones' information many techniques are there but, each of them has one or the other loophole. Moreover, the emerging cross-chain technology to provide interoperability is another part of concern for blockchains. In this paper, the concept of security and privacy is studied in relation to blockchain technology and how the blockchain network is more secure as compared to other networks. Also, the survey has been done on the advancement of blockchain in different applications such as e-commerce, health care, etc. and techniques based on private information retrieval to maintain privacy of data has also been studied. Further, the analysis has been done to conjugate the blockchain and private information retrieval to provide better security and privacy to the internet users.
Noether Networks: Meta-Learning Useful Conserved Quantities

Progress in machine learning (ML) stems from a combination of data availability, computational resources, and an appropriate encoding of inductive biases. Useful biases often exploit symmetries in the prediction problem, such as convolutional networks relying on translation equivariance. Automatically discovering these useful symmetries holds the potential to greatly improve the performance of ML systems, but still remains a challenge. In this work, we focus on sequential prediction problems and take inspiration from Noether's theorem to reduce the problem of finding inductive biases to meta-learning useful conserved quantities. We propose Noether Networks: a new type of architecture where a meta-learned conservation loss is optimized inside the prediction function. We show, theoretically and experimentally, that Noether Networks improve prediction quality, providing a general framework for discovering inductive biases in sequential problems.
