Generative AI for Medical Imaging: extending the MONAI Framework (2023)

Recent advances in generative AI have brought incredible breakthroughs in several areas, including medical imaging. These generative models have tremendous potential not only to help safely share medical data via synthetic datasets but also to perform an array of diverse applications, such as anomaly detection, image-to-image translation, denoising, and MRI reconstruction. However, due to the complexity of these models, their implementation and reproducibility can be difficult. This complexity can hinder progress, act as a use barrier, and dissuade the comparison of new methods with existing works. In this study, we present MONAI Generative Models, a freely available open-source platform that allows researchers and developers to easily train, evaluate, and deploy generative models and related applications. Our platform reproduces state-of-art studies in a standardised way involving different architectures (such as diffusion models, autoregressive transformers, and GANs), and provides pre-trained models for the community. We have implemented these models in a generalisable fashion, illustrating that their results can be extended to 2D or 3D scenarios, including medical images with different modalities (like CT, MRI, and X-Ray data) and from different anatomical areas. Finally, we adopt a modular and extensible approach, ensuring long-term maintainability and the extension of current applications for future features.

Synthesis of Nickel Fumarate and Its Electrochemical Properties for Li-Ion Batteries (2021)

Metal–organic frameworks (MOFs) have found a potential application in various domains such as gas storage/separation, drug delivery, catalysis, etc. Recently, they have found considerable attention for energy storage applications such as Li- and Na-ion batteries. However, the development of MOFs is plagued by their limited energy density that arises from high molecular weight and low volumetric density. The choice of ligand plays a crucial role in determining the performance of the MOFs. Here, we report a nickel-based one-dimensional metal-organic framework, NiC4H2O4, built from bidentate fumarate ligands for anode application in Li-ion batteries. The material was obtained by a simple chimie douce precipitation method using nickel acetate and fumaric acid. Moreover, a composite material of the MOF with reduced graphene oxide (rGO) was prepared to enhance the lithium storage performance as the rGO can enhance the electronic conductivity. Electrochemical lithium storage in the framework and the effect of rGO on the performance have been investigated by cyclic voltammetry, galvanostatic charge–discharge measurements, and EIS studies. The pristine nickel formate encounters serious capacity fading while the rGO composite offers good cycling stability with high reversible capacities of over 800 mAh g−1.
Scanning force microscopy study of the morphology of spin‐cast molecular‐imprinted nylon thin films (2004)

Abstract The morphology of thin, selectively imprinted films of Nylon‐6 was investigated by scanning force microscopy. Four amino acids were used as template molecules in the spin‐cast films. Film thickness ranged from 2 µm to 500 nm, depending on the nylon and template concentration in the casting solution. The thin‐film properties, including the presence of nanometer‐ to micrometer‐sized pores, are clearly associated with the imprinting process. The larger features observed by scanning force microscopy are attributed to amino acid clustering during the casting process. Copyright © 2004 John Wiley &amp; Sons, Ltd.
REMOVING DISTURBING HARMONICS IN OPERATIONAL MODAL ANALYSIS (2007)

In Operational Modal Analysis applications, it is assumed that the structure is excited by white noise. However, in some cases, the operational vibration data are acquired while rotating equipment is active in the background or while it is even the main source of excitation. The structural responses will then consists of a broadband response from which the structural modes can be determined and additional harmonic response at discrete frequencies, which are disturbing the parameter identification process. Sometimes, the harmonic response is dominating and the Operational Modal Analysis methods only find poles at these harmonic frequencies. Therefore, it is desired to try to remove the disturbing harmonics from the data before applying Operational Modal Analysis. In this paper, a method that serves this purpose will be discussed. If the fundamental frequency of the disturbing harmonics is not known, it will be estimated by applying a “tacho-less rpm extraction” procedure. Using the (possibly fluctuating) rpm, the data can be converted to the angle domain and, then time (or better: angle) synchronous averaging is applied to remove the harmonics. This procedure will be illustrated using simulated data as well as real industrial operational data from an in-flight helicopter test and from a running large diesel engine.
The emergence of rare nocardiosis following allogeneic hematopoietic stem cell transplantation in the era of molecular taxonomy (2019)

Newly identified Nocardia species have various antimicrobial susceptibility patterns. Long-term maintenance therapy could be challenging due to the adverse events of antimicrobials, especially in the allo-HSCT setting. Prudent evaluation is crucial for selecting a second-line or further treatment options.
Effects of different cavity designs on fracture load of fiber-reinforced adhesive fixed dental prostheses in the anterior region. (2013)

Different preparation designs (inlay-retained, surface-retained) had no significant effect on fracture strength of FRA-FDPs in the anterior region. However, a cantilever design exhibited significantly lower fracture strength. Delamination of the veneering composite was observed as the primary failure type after fracture tests.
Analysis of aerodynamic performance of high‐speed rotational components for MEMS based turbomachinery considering effects of tip clearance and diabatic heat transfer (2021)

Abstract This paper addresses a fundamental design guideline for rotational components of a micro‐scale gas turbine engine considering an interaction between geometrical structure and aerodynamics. The rotational components of the micro‐scale gas turbine engine may be subjected to the centrifugal stress due to high‐speed rotation. The efficiency of each component is strongly controlled by geometrical clearance between rotational and stationary components, and heat transfer from the turbine to the compressor. Therefore, the elastic deformations due to the centrifugal stress and heat transfer have important role to determine the practical aerodynamic performance of the rotational components. A new sophisticated geometrical structure was introduced to the rotational components to control the elastic deformation and maintain the compressor efficiency that is necessary to hold the minimum requirement for the thermodynamic cycle.
Convergence of Tikhonov regularization for solving ill-posed operator equations with solutions defined on surfaces (2015)

We study Tikhonov regularization for solving ill--posed operator equations where the solutions are functions defined on surfaces. One contribution of this paper is an error analysis of Tikhonov regularization which takes into account perturbations of the surfaces, in particular when the surfaces are approximated by spline surfaces. Another contribution is that we highlight the analysis of regularization for functions with range in vector bundles over surfaces. We also present some practical applications, such as an inverse problem of gravimetry and an imaging problem for denoising vector fields on surfaces, and show the numerical verification.
The Behavior of Oxygen Precipitates in Silicon at High Process Temperature (1990)

The precipitation kinetics of oxygen and the evolution of the precipitate density in preannealed CZ silicon wafers was studied in the temperature range between 950° and 1150°C. It is shown that the number of oxygen nuclei that were created during a 700° or 800°C preanneal decreases exponentially with increasing process temperature. The density of oxygen precipitates in the bulk of the wafer decreases at high temperatures by an empirically determined activation energy of 3.15 eV.
Tweet2Vec: Learning Tweet Embeddings Using Character-level CNN-LSTM Encoder-Decoder (2016)

We present Tweet2Vec, a novel method for generating general-purpose vector representation of tweets. The model learns tweet embeddings using character-level CNN-LSTM encoder-decoder. We trained our model on 3 million, randomly selected English-language tweets. The model was evaluated using two methods: tweet semantic similarity and tweet sentiment categorization, outperforming the previous state-of-the-art in both tasks. The evaluations demonstrate the power of the tweet embeddings generated by our model for various tweet categorization tasks. The vector representations generated by our model are generic, and hence can be applied to a variety of tasks. Though the model presented in this paper is trained on English-language tweets, the method presented can be used to learn tweet embeddings for different languages.
Coordinating fuel inventory and electric power generation under uncertainty (2002)

The authors discuss the problem of hedging between the natural gas and electric power markets. Based on multiple forecasts for natural gas prices, natural gas demand, and electricity prices, a stochastic optimization model advises a decision maker on when to buy or sell natural gas and when to transform gas into electricity. For relatively small models, branch-and-bound solves the problem to optimality. Larger models are solved using Benders decomposition and Lagrangian relaxation. They apply their approach to the system of an electric utility and succeed in solving problems with 50000 binary variables in less than 4 min to within 1.16% of the optimal value.
Prevention of infection after total joint replacement. Experiments with a canine model. (1988)

An experiment was done in dogs to evaluate how efficient each of several techniques was in preventing infection after a total joint arthroplasty. The techniques that were studied were intraoperative irrigation with saline solution or with antimicrobial solution, perioperative systemic administration of antibiotics, and the addition of an antibiotic to bone cement. Irrigation with saline solution did not reduce the incidence of infection. A slight reduction was found after irrigation with neomycin solution and after systemic administration of cefazolin solution. The use of bone cement containing gentamicin caused a statistically significant reduction in the rate of infection; in fact, no infection developed in any animal that was treated with bone cement containing gentamicin. There was excellent but not absolute correlation between findings on culture that indicated the presence of infection and histological evidence of inflammation.
CopyCat2: A Single Model for Multi-Speaker TTS and Many-to-Many Fine-Grained Prosody Transfer (2022)

In this paper, we present CopyCat2 (CC2), a novel model capable of: a) synthesizing speech with different speaker identities, b) generating speech with expressive and contextually appropriate prosody, and c) transferring prosody at fine-grained level between any pair of seen speakers.We do this by activating distinct parts of the network for different tasks.We train our model using a novel approach to two-stage training.In Stage I, the model learns speaker-independent word-level prosody representations from speech which it uses for many-to-many finegrained prosody transfer.In Stage II, we learn to predict these prosody representations using the contextual information available in text, thereby, enabling multi-speaker TTS with contextually appropriate prosody.We compare CC2 to two strong baselines, one in TTS with contextually appropriate prosody, and one in fine-grained prosody transfer.CC2 reduces the gap in naturalness between our baseline and copy-synthesised speech by 22.79%.In fine-grained prosody transfer evaluations, it obtains a relative improvement of 33.15% in target speaker similarity.
Morphological and Biochemical Identification of Apoptosis in Small, Medium, and Large Bovine Follicles and the Effects of Follicle-Stimulating Hormone and Insulin-Like Growth Factor-I on Spontaneous Apoptosis in Cultured Bovine Granulosa Cells1 (2000)

The first objective of this study was to determine whether the death of bovine granulosa cells (GC) isolated from small (</= 4 mm), medium (5-8 mm), and large (> 8 mm) follicles during follicular atresia occurs by apoptosis. The second objective was to establish an in vitro model system to elucidate the developmental (GC from follicles of different sizes) and hormonal (FSH and insulin-like growth factor-I [IGF-I]) regulation of bovine GC apoptosis during follicular atresia. Bovine ovaries were obtained from a nearby slaughterhouse. Follicles were classified by morphometric criteria as healthy or atretic. Apoptosis in GC from follicles of different sizes was analyzed by both morphological and biochemical methods. Bovine GC were cultured for 48 h at a density of 5 x 10(6) cells/ml in serum-free media at 39 degrees C to determine the effects of FSH and IGF-I on apoptosis. The results showed that apoptosis occurred in GC from all sizes of follicles. Apoptosis in GC was also detected in some healthy follicles. Degenerate GC displayed the morphological characteristics of apoptosis, including nuclei with marginated chromatin, a single condensed nucleus, multiple nuclear fragments, and/or membrane-bound structures containing variable amounts of chromatin and/or cytoplasm (apoptotic bodies). All GC classified as apoptotic on the basis of their morphology contained fragmented DNA measured by the terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) technique. Cells that had undergone apoptosis were observed mainly in GC and in scattered theca cells. Throughout the GC layer, apoptotic cell death was more prevalent among antral GC than among mural GC. Interestingly, morphological results showed that no apoptosis occurred in cumulus cells. A time-dependent, spontaneous onset of apoptosis occurred in GC from small, medium, and large follicles during in vitro serum-free culture. The rate of DNA fragmentation in the culture of GC from small follicles was higher than that from medium and large follicles. FSH attenuated apoptotic cell death in GC from medium follicles more effectively than in those from small follicles. IGF-I also suppressed apoptosis in cultured GC from small follicles. In conclusion, this study showed that 1) GC death during bovine follicular development and atresia occurs by apoptosis; 2) apoptosis occurs in GC and theca cells; however, apoptosis does not occur in cumulus cells even in atretic antral follicles; 3) GC from all small, medium, and large follicles undergo spontaneous onset of apoptosis when cultured under serum-free conditions; and 4) FSH and IGF-I can attenuate apoptosis in cultured bovine GC.
Ultra-wideband radar (2005)

Here, we present a description of a block scheme, characteristics, specific features of design and results of testing for a prototype of the ultrawideband (UWB) radar, which has been developed by Russian UWB group researchers at Moscow Aviation Institute at "analog and digital radio systems" department (www.uwbgroup.ru). The prototype was designed within a research work, which we are conducting on the state order from one of Russian federation state institutions. The UWB radar is intended for detection of moving targets at a distance of several kilometers. The radar design is divided into two stages. In the first stage, we have produced a radar prototype, which incorporates a low power narrow-pulse generator (NPG). During laboratory test, the prototype has afforded the detection of moving targets at the distance of up to one hundred meters. Thereby, the validity of technical solutions used for the whole radar's and radar unit's design was confirmed. In the second stage, we plan to conduct field tests of the radar prototype equipped with a high power NPG.
A Study on the Social Image and Make-up Characteristics of Korean Women in 1970s (2008)

The purpose of this study is to compare the social image and the external image of a Korean woman in 1970s and find out that the make-up can provide an important clue to examine the image of a woman in a given period. The research scope covered 10 top news of the daily newspapers and articles of women's magazines. A focus was made to an analysis on words and photos from them. The relationship of each image scale was examined by comparing the linguistic image scale and the visual image scale. The results were as follows : First, a frugal and tidy image. It was the look of our tidy, simple, traditional and classic woman. Second, an image of a cute and pure lady of refined manners. In 1970s, women were supposed to be 'a loving wife', a cultured female image with a faithful role of a 'wise mother' and a lady of refined manners as the best value. Third, a frivolous and decadent image. Double-faced image of a woman which included the women, who had to live as the lady of refined manners during the daytime and seductive woman during the night. Fourth, an image of a contemporary working woman. It was the image as a chic, confident and dignified working woman requested by the society of the times. Namely, it can be understood that women had a make-up of a soft and gorgeous tone as an expression of a will to keep a confident and female aspect in the course of working in the society by the women experiencing 1970s, the turbulent period. Consequently, it is possible to understand that the make-up was utilized as a means to express an ideal beauty of the time pursuant to the historical background or feature.
Enhanced Retrieval of Taste Associative Memory by Chemogenetic Activation of Locus Coeruleus Norepinephrine Neurons (2020)

The ability of animals to retrieve memories stored in response to the environment is essential for behavioral adaptation. Norepinephrine (NE)-containing neurons in the brain play a key role in the modulation of synaptic plasticity underlying various processes of memory formation. However, the role of the central NE system in memory retrieval remains unclear. Here, we developed a novel chemogenetic activation strategy exploiting insect olfactory ionotropic receptors (IRs), termed "IR-mediated neuronal activation," and used it for selective stimulation of NE neurons in the locus coeruleus (LC). <i>Drosophila melanogaster</i> IR84a and IR8a subunits were expressed in LC NE neurons in transgenic mice. Application of phenylacetic acid (a specific ligand for the IR84a/IR8a complex) at appropriate doses induced excitatory responses of NE neurons expressing the receptors in both slice preparations and <i>in vivo</i> electrophysiological conditions, resulting in a marked increase of NE release in the LC nerve terminal regions (male and female). Ligand-induced activation of LC NE neurons enhanced the retrieval process of conditioned taste aversion without affecting taste sensitivity, general arousal state, and locomotor activity. This enhancing effect on taste memory retrieval was mediated, in part, through α<sub>1</sub>- and β-adrenergic receptors in the basolateral nucleus of the amygdala (BLA; male). Pharmacological inhibition of LC NE neurons confirmed the facilitative role of these neurons in memory retrieval via adrenergic receptors in the BLA (male). Our findings indicate that the LC NE system, through projections to the BLA, controls the retrieval process of taste associative memory.<b>SIGNIFICANCE STATEMENT</b> Norepinephrine (NE)-containing neurons in the brain play a key role in the modulation of synaptic plasticity underlying various processes of memory formation, but the role of the NE system in memory retrieval remains unclear.

Effects of inhaled iloprost in acute pulmonary hypertension: Mechanisms beyond pure vasodilation (2009)

Objectives: Prostacyclin inhalation is increasingly used to treat acute pulmonary hypertension (PHT) and right ventricular (RV) dysfunction. Prostacyclins do not only affect vasomotor tone, but may also exert cyclic-adenosine-3′-5′-monophosphate-mediated positive inotropic effects. We studied the role of these different mechanisms in the hemodynamic effects produced by inhaled iloprost (ILO) in an experimental model of acute PHT.
