Battery control with lookahead constraints in distribution grids using reinforcement learning (2022)

In this paper, a computationally efficient real-time control of a battery with lookahead state-of-energy constraints in active distribution grids with distributed energy sources is presented. The goal is to follow a previously computed dispatch plan or to optimize a monetary cost from buying and selling power at the point of common coupling. However, the lookahead constraints render the battery decisions non-trivial. The current practice in literature to solve this problem is Model Predictive Control (MPC), which does not scale for large grids. Instead, here, we propose a reinforcement learning approach based on the Deep Deterministic Policy Gradient (DDPG) algorithm. To satisfy the lookahead battery constraints we adapt the experience replay technique used in DDPG. To guarantee the satisfaction of the hard grid constraints, we introduce a safety layer that performs constrained optimization. Our approach does not need forecasts contrary to MPC. We perform evaluations on a realistic grid and comparisons with Lyapunov optimization and MPC. We show that we can achieve costs close to MPC and Lyapunov, while reducing the computational time by multiple orders of magnitude.
Boron-containing compounds: chemico-biological properties and expanding medicinal potential in prevention, diagnosis and therapy (2014)

Although uncertainties exist about the mechanism of action of BCCs, increasing evidence about their toxicological profile strongly suggests that many can be safely administered to humans. Even stronger evidence exists regarding the capacity of BCCs to reach multiple targets that are involved in the treatment of common diseases. It seems fair to say that some BCCs will reach the market for medicinal use in the near future, not only for targeting microbial or neoplastic systems but also for acting on cell-signaling processes involved in many other disorders.
The singular value decomposition applied to linear imaging with rectangular arrays (2002)

Two-dimensional arrays find applications in many imaging systems. The concept of the sum coarray of an active imaging system is used to develop techniques which allow a (P+Q)-element, L-shaped array to perform as well as a filled rectangular array composed of (P+1)(Q+1)/2 elements. This result is true for linear, narrowband imaging of far-field objects, and is achieved through additional processing of the data obtained from the L-shaped array. A convenient procedure is formulated in terms of the singular value decomposition of a particular matrix, after which the technique is extended to other array geometries and to passive imaging.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Punicalagin and Ketogenic Amino Acids Loaded Organic Lipid Carriers Enhance the Bioavailability, Mitochondrial β-Oxidation, and Ketogenesis in Maturing Adipocytes (2022)

The identification of lipolytic bioactive compounds via the functional stimulation of carbohydrate response element-binding protein-1 (CREBp-1) and AMP-activated protein kinase (AMPK) is most warranted. Nano lipid carriers (NLCs) are currently being considered within drug delivery development as they facilitate controlled drug release and have intracellular bioavailability after encapsulating the active principles with lipid matrix. The present study has been designed to synthesize punicalagin, and ketogenic amino acids (KAA) loaded with organic lipid carriers to optimize the liposome-assisted intracellular delivery's bioavailability. Punicalagin (PUNI) and KAA (tryptophan, methionine, threonine, lysine, and leucine) were encapsulated with chia seed phospholipids by homogenization, emulsification, and cold ultra-sonication method to obtain nano lipid carriers (NLC). The physicochemical characterization of NLCs has been carried out using Zetasizer, FT-IR, and TEM analysis. Punicalagin and ketogenic amino acid-loaded NLCs (NLC-PUNI-KAA) were identified with an average diameter of 240 to 800 nm. The biosafety of NLC-PUNI-KAA has been evaluated in human mesenchymal stem cells. PI staining confirmed that a 0.4, 0.8 or 1.6μg/dL dose of NLC-PUNI-KAA potentially maintains nuclear integration. NLC-PUNI-KAA treated with maturing adipocytes decreased lipid accumulation and significantly increased the gene expression levels of fatty acid beta-oxidation (PPARγC1α, UCP-1 and PRDM-16) pathways when compared to free PUNI (5 μg/dL) treatment. The lipolytic potential has been confirmed by the functional activation of AMPK and CREBp-1 protein levels. In conclusion, NLC-PUNI-KAA treatment effectively increased mitochondrial efficiency more than free punicalagin or orlistat treated maturing adipocyte. Enhanced lipolysis and decreased hypertrophic adipocyte resulted in decreased adipokine secretion, which has been associated with the suppression of obesity-associated comorbidities and vascular cell inflammation. The bioefficacy and lipolytic potential of water-soluble punicalagin have been improved after functional modification into NLCs.
Experimental realization of an on-chip all-optical analogue to electromagnetically induced transparency (2006)

We show experimentally an all-optical analogue to electromagnetically induced transparency due to coherent interference between two coupled resonators. We measured an EIT-like resonance mode with quality factor of 11,800 using silicon ring resonators.
Optical Generation of Narrow-line RF by Injection Locking of Modulated DFB Lasers (2011)

A pair of commercial DFB lasers has been phase locked using electro-optic modulation and injection seeding. By mixing the locked lasers’ outputs on a photodetector, we have generated RF from 5 to 50 GHz, with a measured linewidth below 2 Hz.
High resolution investigation of the domain kinetics in lithium niobate and lithium tantalate single crystals (2005)

Static domain patterns produced by application of the external electric field in wide temperature range in single crystals of congruent, stoichiometric and MgO doped lithium niobate LiNbO&lt;sub&gt;3&lt;/sub&gt; (LN) and lithium tantalate LiTaO&lt;sub&gt;3&lt;/sub&gt; (LT) were investigated experimentally in great detail. Moreover the domain kinetics has been studied by computer simulation and experimentally in model structure in order to check applicability of the kinetic approach to explanation of the individual domain shape and domain structure evolution for switching from multidomain initial state [1]. The step-by-step kinetic model of the domain growth was realized in the model experiment. Evolution of two-dimensional (2D) domain patterns has been investigated in CLN produced by application of external electric field by 2D electrode grating (Fig. 1). The grating structure has been produced by photolithography and the field has been applied using liquid electrolyte. &amp;amp; more.

α-Subunit selective modulators of GABAAreceptor function as CNS therapeutics (2002)

Abstractγ-Aminobutyric acid (GABA) is the major inhibitory neurotransmitter within the CNS. Many drugs, including the benzodiazepines, exert their effects by modulating the GABAA receptor complex, but side effects are common and reflect, in part, poor subunit selectivity. The subunits are arranged into heteropentamers and this produces a rich diversity of GABAA receptor subtypes, which are potential targets for treating a variety of CNS disorders including epilepsy, anxiety and insomnia, as well as for ameliorating deficiencies arising from neurodegeneration, such as cognitive impairment. The identification of new ligands with improved subunit selectivity should reduce or abolish some of the side effects observed with current drugs, such as tolerance, dependence and withdrawal. This article focuses on new ligands that are reported to selectively recognise particular α-subunits of GABAA receptors and may thereby offer improved treatments for CNS disorders. Only patents and literature since 1998 are necessarily included, although some earlier reports and reviews are also cited. Several publications and patent applications since 1998 disclose new compounds that modulate GABAA receptor function without mentioning whether they have α-subunit selectivity; these compounds, like those known to interact with sites on other GABAA subunits (particularly β), are not within the scope of this review.Keywordsα-subunitγ-aminobutyric acid A(GABAA) receptorsanticonvulsantanxiolyticbenzodiazepineCNScognitionhypnoticsedative
Editorial: A tribute to Bruce Merrifield (2008)

his issue of Biopolymers: Peptide Science is dedicated in the memory of Professor Bruce Merrifield who died on May 14, 2006, at his home in Cresskill, New Jersey.The outpouring of tributes in scientific journals, at the meetings of peptide societies throughout the world, and in the popular press are a testimony to the profound impact that Merrifield's invention of chemical synthesis on solid support has had on today's science.Solid phase peptide synthesis (SPPS) opened new possibilities to solve scientific problems, brought the field of peptide chemistry within the reach of other scientific disciplines, and facilitated the interactions between peptide chemists and scientists with diverse research and medical interests.Bruce Merrifield's invention holds a unique place in the history of 20th century science.Merrifield's path to SPPS was summarized by Dr. William Agosta during the presentation of the degree of Doctor of Science, Honoris Causa, awarded by the Rockefeller University in 1998: ''In chemistry as elsewhere, it is one thing to have a novel idea and another to reduce it to practice.Famous chemists nearly always confine themselves to the pleasure of generating ideas and then depend on younger colleagues to make them work.Over a period of 3 years, Merrifield made his idea work by himself.''This issue brings together the scientific contributions and recollections from Merrifield's coworkers in his laboratory, colleagues from the Rockefeller University, and scientists who interacted with Bruce Merrifield at different stages of his long career, as well as original articles and reviews from the younger generation of peptide chemists who are expanding the concept of SPPS in new directions.The issue is divided into several sections.
Co-Polymerization of Maleimides and Vinyl Ethers:  A Structural Study (1998)

We report on the thermally-induced and photoinduced polymerization of the electron-donating divinyl ether di(4-vinyloxybutyl)succinate (DVBS) and the electron accepting 1,5-bis(maleimido)-2-methylpentane (BMMP) and their monofunctional analogues, dodecylvinyl ether (DDVE), N-methylmaleimide (NMM), and N-phenylmaleimide (NPM). We focus on the stoichiometry of the monomer constituents consumed in the polymerization and the structural identity and bonding configuration(s) of the polymer products. For both BMMP−DVBS and NMM−DDVE, FTIR and 1H NMR data indicate 1:1 stoichiometry for the resulting polymer. For both systems, the polymers are of the alternating donor and acceptor form (DA)n. This result holds for both photoinduced and thermally induced reactions. Structural NMR studies of polymers synthesized from both mono- and difunctional monomers indicate the presence of both cis and trans conformers of the acceptor at the D−A bond. This finding indicates that thermodynamic factors alone are not sufficient to explain the ratio of the conformers and either steric factors or features specific to the transition state play a significant role in determining the conformational distribution of the polymer.
Whole genome association study of quantitative psychosis proneness scales in the general population (2009)

Common concepts of psychosis proneness follow a stress-diathesis model in which the neurobiological vulnerability is expected to be present in the general population as a latent trait or taxon that can be assessed in the form of schizotypic that is psychotic like, enduring personality features by self-rated psychometric tests. We have performed a whole genome association study of such psychosis proneness measures in the general population. For this, we utilized the birth cohort study of northern Finland (NFBC66). Originally, everyone born in the catchment area in 1966 (n=12058) were included in the study. Of these, 4561 (38%) attended the 31-year follow-up and could be included in this stage of the study. The subjects filled out four psychometric scales designed to function as quantitatively measurable proxies of psychosis proneness. The scales were the revised Social Anhedonia Scale, the revised Physical Anhedonia Scale, the Perceptual Aberration Scale and the Golden and Meehl Schizoidia Scale. We have previously used this strategy to show association between markers in DISC1 and Social Anhedonia, a finding that closely replicated earlier associations in schizophrenia and bipolar disorder. The genotyping was performed on Illumina Infinium Assay, using the HumanHap370 marker set. This approach of using quantitative phenotypes that are possible to assess in large population cohorts can be powerful way if identifying genes that predispose also to the related clinical disorders, in this case psychosis.Â  Â
Endoscopic Management of Chronic Pancreatitis (1994)

The indications of endoscopic management for chronic pancreatitis are strictly related to the classification of severe types and to the particular anatomy of the ducts. (1) Impacted or distal calculi without stricture: ESWL followed by EPS and extraction of fragments. (2) Stone(s) and stricture: ESWL, EPS, NPC, and then 10-french plastic stenting. (3) Relapsing strictures (with upward dilatation) after 6-12 months’ stenting: coated self-expanding stent (in a prospective trial), versus surgical laterolateral pancreaticojejunostomy (Partington-Ro-chelle operation). (4) Paraduodenal cyst bulging into the duodenum: ECD ± stenting. (5) Retrogastric pseudocyst: ECG and stenting. (6) Jaundice and/or cholestasis due to stricture of the intrapancreatic CBD: 10-french single or multiple plastic stents for calibration during 3 months. For relapsing cholestasis and stricture, 30-french metal mesh stent versus surgical hepaticojejunostomy. Due to the tremendous variations of the ducts’ anatomy, the method includes drainage through the minor papilla for patients with a dominant Santorini or dorsal duct (table 6). The indications of endoscopic management for chronic pancreatitis are specific and require complete imaging and functional check-up (ERCP, CT scanner, endosonography, pancreatic function tests). The technique is quite difficult and requires high-definition fluoroscopy, appropriate devices and experienced gastrointestinal assistents and radiologists. On these conditions, the complication rate is very low and can usually be medically controlled. Treatment does not compromise any further surgery. Endoscopy makes it possible to avoid or to postpone surgery, the indication for which might become better defined and the patients more carefully selected in the future.
High Linearity 57–66 GHz SiGe Receiver for Outdoor Point-to-Point Communication (2018)

Fully integrated receiver in a superhetrodyne architecture covering the entire 60 GHz frequency range (57-66 GHz) was designed and fabricated in 0.12 μm SiGe technology. The receiver chip includes an image-reject low-noise amplifier (LNA), RF-to-IF mixer, RF variable attenuator, IF variable gain amplifier, quadrature IF-to-baseband de-modulators, tunable baseband filter, phase-locked loop (PLL), and x3 frequency multiplier. The receiver chip achieve maximum gain of 65 dB, 5 dB minimum noise figure, better than 2 dBm IIP3 at high linearity mode, with >75 dB dynamic range, and consumes 630 mW.
Speed-up techniques for ray tracing field prediction models (2005)

One of the main drawbacks of 3D Ray Tracing (RT) field prediction is the high computation time, which is strictly related to complexity and size of the environment database. In the present work two speed up methods for RT algorithms are presented: the first one operates on reducing the size of the input database, the second on reducing the number of rays to be handled by the RT algorithm. The two methods are shown to be effective in cutting computation time virtually without degradation of the results.
Spectrally tunable liquid resonator based on electrowetting (2022)

We present a tunable on-chip liquid resonator in conjunction with a tapered fiber coupling scheme. The resonator consists of a glycerol droplet submerged within an immiscible liquid bath, which mitigates the effects of environmental fluctuations. The platform is fabricated using standard semiconductor techniques, which enable the future integration of photonic components for an on-chip liquid resonator device. The liquid resonator maintains its high Q-factor on chip (10<sup>5</sup>) due to surface tension forming an atomically smooth liquid-liquid interface. Higher Q-factor resonance modes experienced linewidth broadening due to the random excitation of thermal capillary vibrations. Spectral tuning is demonstrated using the electrowetting effect, increasing the surface's wettability and an expansion in the droplet diameter. A maximum spectral tuning of 1.44 nm ± 5 pm is observed by applying 35 V. The tuning range is twice the free spectral range (FSR) of 0.679 nm measured at a pumping wavelength range of 770-775 nm. A 2D axisymmetric finite-element simulation shows resonance modes in good agreement with experimentally measured spectra and with predicted tuning speeds of 20 nm/s.
Direct visual odometry for a fisheye-stereo camera (2017)

We present a direct visual odometry algorithm for a fisheye-stereo camera. Our algorithm performs simultaneous camera motion estimation and semi-dense reconstruction. The pipeline consists of two threads: a tracking thread and a mapping thread. In the tracking thread, we estimate the camera pose via semi-dense direct image alignment. To have a wider field of view (FoV) which is important for robotic perception, we use fisheye images directly without converting them to conventional pinhole images which come with a limited FoV. To address the epipolar curve problem, plane-sweeping stereo is used for stereo matching and depth initialization. Multiple depth hypotheses are tracked for selected pixels to better capture the uncertainty characteristics of stereo matching. Temporal motion stereo is then used to refine the depth and remove false positive depth hypotheses. Our implementation runs at an average of 20 Hz on a low-end PC. We run experiments in outdoor environments to validate our algorithm, and discuss the experimental results. We experimentally show that we are able to estimate 6D poses with low drift, and at the same time, do semi-dense 3D reconstruction with high accuracy. To the best of our knowledge, there is no other existing semi-dense direct visual odometry algorithm for a fisheye-stereo camera.

Transient Accumulation of Nitrite Reductase mRNA in Maize following the Addition of Nitrate (1989)

Expression of the gene coding for nitrite reductase (NiR) is induced upon the addition of nitrate. We have analyzed this induction process in hydroponically grown maize (Zea mays L.) seedlings where the level of nitrate in the medium can be easily manipulated. There is a rapid induction of NiR mRNA upon addition of nitrate, increasing first in the roots and then in the leaves. The rapidity of the response depends on the nitrate concentration and the growth medium. However, the general pattern of expression is the same: the mRNA level increases, reaches a maximum, and then decreases, despite the fact that the nitrate concentration in the medium remains constant. This decline in mRNA level can be quite rapid, particularly in root tissue. If the nitrate is given as a pulse, the mRNA levels decrease even more rapidly. It is clear that the NiR mRNA is short-lived, with a half-life in the roots of less than 30 minutes. The NiR protein level, on the other hand, increases gradually somewhat after the increase in mRNA and remains at high levels at least for 24 hours after the addition of nitrate.

Towards Visual Sociolinguistic Network Analysis (2021)

Investigation of social networks formed by individuals in various contexts provides numerous interesting and important challenges for researchers and practitioners in multiple disciplines. Within the field of variationist sociolinguistics, social networks are analyzed in order to reveal the patterns of language variation and change while taking the social, cultural, and geographical aspects into account. In this field, traditional approaches usually focusing on small, manually collected data sets can be complemented with computational methods and large digital data sets extracted from online social network and social media sources. However, increasing data size does not immediately lead to the qualitative improvement in the understanding of such data. In this position paper, we propose to address this issue by a joint effort combining variationist sociolinguistics and computational network analyses with information visualization and visual analytics. In order to lay the foundation for this interdisciplinary collaboration, we analyse the previous relevant work and discuss the challenges related to operationalization, processing, and exploration of such social networks and associated data. As the result, we propose a roadmap towards realization of visual sociolinguistic network analysis.
