Cryo-Electron Microscopic Grid Preparation for Time-Resolved Studies using a Novel Robotic System, Spotiton (2021)

The capture of short-lived molecular states triggered by the early encounter of two or more interacting particles continues to be an experimental challenge of great interest to the field of cryo-electron microscopy (cryo-EM). A few methodological strategies have been developed that support these "time-resolved" studies, one of which, Spotiton-a novel robotic system-combines the dispensing of picoliter-sized sample droplets with precise temporal and spatial control. The time-resolved Spotiton workflow offers a uniquely efficient approach to interrogate early structural rearrangements from minimal sample volume. Fired from independently controlled piezoelectric dispensers, two samples land and rapidly mix on a nanowire EM grid as it plunges toward the cryogen. Potentially hundreds of grids can be prepared in rapid succession from only a few microliters of a sample. Here, a detailed step-by-step protocol of the operation of the Spotiton system is presented with a focus on troubleshooting specific problems that arise during grid preparation.
Speciation of selenium in the mammalian organism (1998)

As almost all of the selenium present in the mammalian organism is protein-bound, speciation is mostly concerned with the determination of the different selenium-containing proteins. Information on their distribution and their concentrations in the different tissues of the rat was obtained by means of tracer procedures which, after application of 75Se-selenite with a very high specific activity to selenium-depleted animals and electrophoretic separation of the labelled proteins, allow the determination of these compounds in the pmol to fmos range. A method was developed for the determination of selenocysteine and selenomethionine in the selenium-containing proteins. The identification of specific selenoproteins was achieved by analysis of their selenoamino acid residues and by studies on their characteristics and possible biological functions. This is being followed by the development of methods for the quantitative analysis of the selenoproteins in questions in the tissues of animals and man. In this paper the strategies and procedures used in the identification, characterization and determination of the selenium species present in the mammalian organism will be discussed.

High Q-factor compact coils having non-uniform wire width for wireless power transfer system (2016)

Compact coil is designed at 6.78 MHz for wireless power transfer (WPT) system. The proposed coil is optimized by adjusting the gap between wires, scaling factor, and the number of turns to achieve high quality factor (Q-factor), and its Q-factor is 263. The Q-factor of the proposed coil exhibits 1.21 times higher than conventional coil. The coil is made on thin substrate with a low relative permittivity and a loss tangent to decrease influence of the substrate, and the coil size is 100 mm × 100 mm × 0.4 mm. The measured efficiency is shown as 95% at 50 mm and 30% at 200 mm. The compact coil having non-uniform wire width has higher efficiency than that of conventional coil. The proposed coil can be utilized for the various mobile applications.

Spatio-Temporal Agnostic Deep Learning Modeling of Forest Fire Prediction Using Weather Data (2023)

This research provides a spatio-temporal agnostic framework based on subsampling to generate generic deep learning models using publicly available weather data and to predict the probability of forest fire and severity. The aim is to show that this framework can be used to subsample and generate a balanced dataset for generic deep learning models to improve predictions for forest fires. The framework works for binary classification and regression deep learning models. It also works with limited variations between fire and non-fire data. Using this framework, 45 of the binary classification models built produced an F1Score greater than 0.95 while 35 of 54 regression models produced an R <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> Score greater than 0.91.
From tracking to advanced surveillance (2004)

Using a simple but robust real-time algorithm that allows tracking of multiple objects in complex environments, the authors propose a wide range application in automatic surveillance by linking blobs' information, in terms of trajectories and positions, with the events to be detected. Real-time is achieved reducing the computation time avoiding the use of colour in the segmentation stage and statistical prediction in the tracking stage and using instead segmentation based on luminance contrast and tracking based on the overlapping information from bounding boxes from two consecutive frames.
Symmetrical number system phase sampled interferometer direction finding antennas (1998)

Abstract : A novel phase sampled interferometer Direction Finding (DF) antenna architecture is described. Based on the optimum symmetrical number system (OSNS) the analog spatial filtering operation is broken down into a number of parallel sub operations (moduli) that are of smaller complexity. One two-element interferometer is used for each sub operation and only requires a precision in accordance with its modulus. A much higher spatial resolution is achieved after the different OSNS moduli are used and the filtering results of these low precision sub operations are recombined. The use of the symmetrically folding phase waveform provides for a straight forward implementation of a high resolution DF antenna. Simulated and experimental results are shown to numerically evaluate the feasibility of the design. Spatial encoding errors that may occur due to the angle-of-arrival being located about a code transition point are also quantified.

Frame-Online DNN-WPE Dereverberation (2018)

Signal dereverberation using the weighted prediction error (WPE) method has been proven to be an effective means to raise the accuracy of far-field speech recognition. But in its original formulation, WPE requires multiple iterations over a sufficiently long utterance, rendering it unsuitable for online low-latency applications. Recently, two methods have been proposed to overcome this limitation. One utilizes a neural network to estimate the power spectral density (PSD) of the target signal and works in a block-online fashion. The other method relies on a rather simple PSD estimation which smoothes the observed PSD and utilizes a recursive formulation which enables it to work on a frame-by-frame basis. In this paper, we integrate a deep neural network (DNN) based estimator into the recursive frame-online formulation. We evaluate the performance of the recursive system with different PSD estimators in comparison to the block-online and offline variant on two distinct corpora. The REVERB challenge data, where the signal is mainly deteriorated by reverberation, and a database which combines WSJ and VoiceHome to also consider (directed) noise sources. The results show that although smoothing works surprisingly well, the more sophisticated DNN based estimator shows promising improvements and shortens the performance gap between online and offline processing.
On the Mechanism of Dielectric Breakdown of Solids (1980)

The mechanism of dielectric breakdown in solids, according to recent experimental evidence, involves the creation of a gaseous channel through the dielectric. The high conductance of breakdown appears to be associated with this channel, not with conduction through the solid itself. The central problem in the theory of dielectric breakdown in solids is thus to explain the development, in a strong electric field, of a macroscopic gaseous channel through the dielectric before the large change of conductance characteristic of dielectric breakdown. Recent experimental results will be reviewed and a gaseous model of breakdown in solids will be described in terms of four stages: Formative, Tree Initiation, Tree Growth and Return Streamer. The model is still in the stage of phenomenological development.
Effect of temperature and/or sweetness of beverages on body composition in rats (2020)

Sweetened beverages are mainly consumed cold and various processes are activated in response to external temperature variations. However, the effect of internal temperature variations through the ingestion of cold beverages is far from clear. Two experiments were conducted to investigate the effect of beverage temperature on body composition. Sprague-Dawley rats (5-6-week-old males) had free access to food and beverage for 8 weeks. Energy intake, body weight and body composition were monitored. In Expt 1, two groups of rats (n 9) consumed water at room temperature (NW about 22°C) or cold (CW about 4°C). In Expt 2, rats were offered room-temperature (N) or cold (C) sweetened water (10 % sucrose CSu (n 7) and NSu (n 8); or 0·05 % acesulfame K CAk (n 6) and NAk (n 8)) for 12 h, followed by plain water. Our results show that in Expt 1, CW had higher lean body mass (P < 0·001) and lower body fat gain (P = 0·004) as compared with NW. In Expt 2, body weight (P = 0·013) and fat (P ≤ 0·001) gains were higher in the non-energetic sweetened groups, while lean body mass was not affected by the type of sweeteners or temperature. In conclusion, cold water ingestion improved lean body mass gain and decreased fat gain because of increased energy expenditure, while non-energetic sweetener (acesulfame K) increased body fat gain due to improved energy efficiency. Internal cold exposure failed to increase energy intake in contrast to that of external cold exposure.

Standardization Status of Immersive Video Coding (2019)

Based on increasing availability of capture and display devices dedicated to immersive media, coding, and transmission of these media has recently become a highest-priority subject of standardization. Different levels of immersiveness are defined with respect to an increasing degree of freedom in terms of movements of the observer within the immersive media scene. The level ranges from three degrees of freedom allowing the user to look around in all directions from a fixed point of view to six degrees of freedom, where the user can freely alter the viewpoint within the immersive media scene. The moving pictures experts group (MPEG) of ISO/IEC is developing a standards suite on “Coded Representation of Immersive Media,” called MPEG-I, to provide technical solutions for building blocks of the media transmission chain, ranging from architecture, systems tools, coding of video and audio signals, to point clouds and timed text. In this paper, an overview on recent and ongoing standardization efforts in this area is presented. While some specifications, such as high efficiency video coding or version 1 of the omnidirectional media format, are already available, other activities are under development or in the exploration phase. This paper addresses the status of these efforts with a focus on video signals, indicates the development timelines, summarizes the main technical details, and provides pointers to further points of reference.

An Efficient Filter Strategy for Theta-Join Query in Distributed Environment (2017)

Theta-join query is a very popular application in traditional databases, but due to tremendous computation cost and communication cost in distributed environment, it is not efficiently processed for big data. Current researches focus on processing theta-join by using MapReduce framework, which mainly consider the overheads of load balance in the network, when the data sets become larger, massive intermediate results lead to high communication cost. In this work, we propose a filter method for theta-join to reduce the computation and communication cost in distributed environment, which can effectively improve the theta-join query. We consider both the load balance in the cluster and the memory cost in the parallel framework. We have implemented our method in a popular general-purpose data processing framework, Spark. The experimental results demonstrate that our method can significantly improve the performance of theta-joins comparing the state-of-art solutions.

Capillary Isoelectric Focusing-Tandem Mass Spectrometry and Reversed-Phase Liquid Chromatography-Tandem Mass Spectrometry for Quantitative Proteomic Analysis of Differentiating PC12 Cells By Eight-Plex Isobaric Tags for Relative and Absolute Quantification (2013)

We report the application of capillary isoelectric focusing for quantitative analysis of a complex proteome. Biological duplicates were generated from PC12 cells at days 0, 3, 7, and 12 following treatment with nerve growth factor. These biological duplicates were digested with trypsin, labeled using eight-plex isobaric tags for relative and absolute quantification (iTRAQ) chemistry, and pooled. The pooled peptides were separated into 25 fractions using reversed-phase liquid chromatography (RPLC). Technical duplicates of each fraction were separated by capillary isoelectric focusing (cIEF) using a set of amino acids as ampholytes. The cIEF column was interfaced to an Orbitrap Velos mass spectrometer with an electrokinetically pumped sheath-flow nanospray interface. This HPLC-cIEF-electrospray-tandem mass spectrometry (ESI-MS/MS) approach identified 835 protein groups and produced 2,329 unique peptides IDs. The biological duplicates were analyzed in parallel using conventional strong-cation exchange (SCX)-RPLC-ESI-MS/MS. The iTRAQ peptides were first separated into eight fractions using SCX. Each fraction was then analyzed by RPLC-ESI-MS/MS. The SCX-RPLC approach generated 1,369 protein groups and 3,494 unique peptide IDs. For protein quantitation, 96 and 198 differentially expressed proteins were obtained with RPLC-cIEF and SCX-RPLC, respectively. The combined set identified 231 proteins. Protein expression changes measured by RPLC-cEIF and SCX-RPLC were highly correlated.
34. Cardiovascular Effects of CO 2 Pneumoperitoneum (2005)

Any surgical procedure elicits a physiologic response from the patient. This response is both acute, occurring during the procedure, and of intermediate duration, during the healing/recovery phase. The causes of the host response are multifactorial and include the psychological stress induced by the need for surgery, the effects of medication and anesthetic agents, the hormonally mediated stress response to the surgical insult, and mechanical effects peculiar to the procedure. These mechanical effects include, but are not limited to, volume shifts from positioning, compression from retraction and exposure, induced transient organ ischemia, hypovolemia from blood and fluid loss, hypothermia, and a myriad of other factors. Perioperative surgical stress can affect any of the major organ systems. Of primary concern is its impact on the cardiovascular system, as this can be difficult to control and may be potentially dangerous for the patient. Minimally invasive surgical techniques, as defined by access via small incisions, operative imagery by videoscopy, and exposure by instillation of insufflated gas, offer some physiologic advantage to patients (e.g., a lessened surgical stress response) at the cost of introducing other unique cardiovascular variables. Cardiovascular changes in minimally invasive surgery can be categorized as those resulting from patient positioning, neurologically mediated responses, hypothermia, and absorption of insufflated gas as well as the pressure effects of insufflating a body compartment.

Influence of Binder Content and Particle Size on Green Strength of WPP Parts (1995)

Wet powder pouring (WPP) was developed as an alternative near net shape process to metal injection moulding (MIM). The amount of binder, which is necessary to obtain a sufficient green strength, is relatively low (2–5 vol.-%) compared to the amount used in the MIM process (about 30 vol.-%). This is advantageous with respect to short debinding times and low residual carbon and oxygen contaminations. A further reduction of the binder content or the application of the WPP process to new materials would be promoted by an understanding of the dependence of green strength on particle characteristics and binder content. In the present investigation the green strengths of stainless steel WPP parts were determined for different particle size distributions and different binder contents (2–8 vol.-%). The green strength was in the range 3 to 7 MN m−2 and the fracture mode was always brittle. A simple fracture mechanical model was developed, which was able to explain the observed relations between binder content, particle size, and green strength. PM/0658

The roles of serotonin in cell adhesion and migration, and cytoskeletal remodeling (2021)

Serotonin is well known as a neurotransmitter. Its roles in neuronal processes such as learning, memory or cognition are well established, and also in disorders such as depression, schizophrenia, bipolar disorder, and dementia. However, its effects on adhesion and cytoskeletal remodelling which are strongly affected by 5-HT receptors, are not as well studied with some exceptions for e.g. platelet aggregation. Neuronal function is strongly dependent on cell-cell contacts and adhesion-related processes. Therefore the role played by serotonin in psychiatric illness, as well as in the positive and negative effects of neuropsychiatric drugs through cell-related adhesion can be of great significance. In this review, we explore the role of serotonin in some of these aspects based on recent findings.
