Chiralsense : sensing chirality using cavity-enhanced polarimetry: advances in sensitivity and time-resolution

Chiral sensing is crucial to many fields, constituting a multibillion Euro industry. The polarimetric techniques of optical rotation (OR) and circular dichroism (CD) are the most widely-used techniques for the analysis of chiral samples, ranging from the measurement of protein structure, to quality control in the pharmaceutical, chemical, cosmetic, and food industries. In general, the OR and CD signals are very small, which place severe constraints on detection sensitivity and time-resolution. Through the ERC grant TRICEPS, we have developed a groundbreaking cavity-based polarimeter [Sofikitis et al. Nature 514, 76 (2014)] with 3 main advantages: (a) The OR and CD signals are enhanced by the number of cavity passes (typically 1000); (b) birefringent backgrounds are suppressed; (c) signal reversals give absolute polarimetry measurements, not requiring the sample to be removed to measure a null sample. These advantages represent orders-of-magnitude improvements in sensitivity, acquisition time, and sample size, with respect to commercially available polarimeters, and will reduce measurement time, sample sizes, and costs in the chiral sensing industry. We propose, through CHIRALSENSE, to: (1) file a non-provisional US patent application, to follow our filing of a US provisional patent application for our polarimeter, which will provide IPR protection for the first stages of the product development; (2) demonstrate our existing CHIRALSENSE polarimeter to leading polarimetry companies, by performing measurements on commercial-standard samples; and (3) adapt our polarimeter to measure complex samples separated using HPLC (high-performance liquid chromatography) for analytical chemistry applications, to be demonstrated to leading HPLC companies.
Methodologies and data mining techniques for the analysis of big data based on longitudinal population and epidemiological registers

European societies face rapid social changes, challenges and benefits, which can be studied with traditional tools of analysis, but with serious limitations. This rapid transformation covers changes in family forms, fertility, the decline of mortality and increase of longevity, and periods of economic and social instability. Owing to population ageing across Europe, countries are now the experiencing the impact of these rapid changes on the sustainability of their welfare systems. At the same time, the use of the space and residential mobility has become a key topic, with migrations within the EU countries and from outside Europe being at the center of the political agenda. Over the past decade research teams across Europe have been involved in the development and construction of longitudinal population registers and large research databases, while opening up avenues for new linkages between different data sources (ie administrative and health data) making possible to gain an understanding of these fast societal transformations. However, in order to work with these types of datasets requires advanced skills in both data management and statistical techniques. LONGPOP aims to create network to utilize these different research teams to share experiences, construct joint research, create a training track for specialist in the field and increase the number of users of these large – possibly underused - databases, making more scientists and stakeholders aware of the richness in the databases.
Spike code and information flow in cultured neuronal networks and its simulation on 2D mesh network

It's important to investigate natural intelligence how the signal/ information is flown in neuronal network. We observed spike trains produced by one-shot electrical stimulation with 8 × 8 multi-electrodes in cultured neuronal networks. Each electrode accepted spikes from several neurons. We then constructed code flow maps as movies of the electrode array to observe the code flow especially of “1101” and “1011.” To quantify the flow, we calculated the cross-correlations of the maximum direction of the codes with lengths less than 8. Normalized cross-correlations in the maximum direction were almost constant irrespective of code. Thus, the analysis suggested that the local codes for electrode flow maintained the code shape to some extent and conveyed information in the neural network. Then we made simulation of such code flow.

Fostered by the fellowship, a leading expert in photonic sensing technologies is expected and will contribute greatly to EU industries and academic communities.
An Iterative Framework for EEG-based Image Search: Robust Retrieval with Weak Classifiers

We revisit the framework for brain-coupled image search, where the Electroencephalography (EEG) channel under rapid serial visual presentation protocol is used to detect user preferences. Extending previous works on the synergy between content-based image labeling and EEG-based brain-computer interface (BCI), we propose a different perspective on iterative coupling. Previously, the iterations were used to improve the set of EEG-based image labels before propagating them to the unseen images for the final retrieval. In our approach we accumulate the evidence of the true labels for each image in the database through iterations. This is done by propagating the EEG-based labels of the presented images at each iteration to the rest of images in the database. Our results demonstrate a continuous improvement of the labeling performance across iterations despite the moderate EEG-based labeling (AUC <75%). The overall analysis is done in terms of the single-trial EEG decoding performance and the image database reorganization quality. Furthermore, we discuss the EEG-based labeling performance with respect to a search task given the same image database.

Foreign Body Granulomatosis

We studied the clinical and immunologic features of 10 patients with foreign body granulomatosis associated with injection of pentazocine. Five had typical micronodules on chest radiographs, 9 had abnormal 67Ga lung images, and 9 had elevated serum angiotensin-converting enzyme levels. Pulmonary function tests showed significant decreases in diffusing capacity in 8 subjects, but were otherwise normal. Bronchoalveolar lavage fluid had significantly (p less than 0.02) increased total cell numbers (13.8 +/- 7.5 x 10(7) and significantly lower percentages of lymphocytes (2 +/- 1) and neutrophils (2 +/- 1) (p less than 0.02) when compared with that from control subjects. Peripheral blood lymphocytes were normal when expressed as percentages of total leukocytes or as percent T-lymphocytes. Monoclonal antibody determinations of T-lymphocyte subsets (helper and suppressor) were similar to those in control subjects (p = NS). Lymphocyte transformation responses to a variety of antigens and skin test reactivity were normal. Foreign body granulomatosis contrasts with other interstitial lung diseases in its bronchoalveolar lavage cellular profile and in the absence of altered peripheral immunologic indexes.
Staircase modulation applied in a speed controller for small's single/two - phase induction motors

At present, the widespread use of small induction motors for home appliances and other applications justify the development of new drives and motor designs. The aim shall be to save energy and to consume it with a clean absorption of current from the mains. This paper presents an application for the speed control of a small single/two phase induction motor. This application has a cascaded H-bridge multilevel inverter that is controlled through a staircase modulation. These waveforms are composed to obtain a 2-phase voltage system, with variable amplitude and frequency, to feed small electric power drives. The two parameters of the waveforms -amplitude and frequency- in the motor are easily regulated and amplified by means of semiconductors working in PWM mode. This new drive provides advantages as a straightforward control method, simplicity of the design, easily regulated starting torque and its low cost. As a whole, the design leads to a robust, compact, cheap unit, easy to manufacture. In this paper, a new type of control for angle phase is proposed through the staircase modulation for adjustable speed drive for fractional horse-power single/two phase induction motor. Due to the simplicity of design, the control algorithm it is not necessary to implement it using digital signal processors (DSPs) or microcontroller units (MCUs).

The invention relates to a process system (1, 60, 100, 130, 160, 180, 190) comprising heat stores (3,4,30,61,61a-61d,62,62a-62d,110,163-165,181-183, 195-198), which are designed to store heat between an upper (To) and a lower temperature (Tu) and to discharge the same again, and comprising a conduit arrangement (L) for the transport of heat-transporting medium to the heat stores (3,4,30,61,61a-61d,62,62a-62d,110,163-165,181-183, 195-198) and away from the latter again, wherein a plurality of operable process units (2,63,63a-63d,161-162, 184-185,191-193) are provided between the upper (To) and the lower tempreature (T(u) and are each arranged such that the process units are capable of operation between two heat stores (3,4,30,61,61a-61d,62,62a-62d,110,163-165,181-183, 195-198), through the conduit arrangement (L). This results in a reduced outlay for the production of the process system.
Ultra-Low power and highly-scalable interfaces for the internet of things

The era of the Internet of Things (IoT), in which every physical entity includes power-autonomous embedded electronics, capturing relevant information by sensors and interacting with objects and humans in a globally interconnected network, is bringing about new challenges in Integrated Circuit (IC) design. The performance of ICs in terms of integration density, power consumption and cost, in fact, is the only limiting factor to the feasibility and/or to the widespread diffusion of IoT-based solutions.
Digital ICs in the most recent nanoscale CMOS technologies are keeping the pace of IoT requirements. On the contrary, the implementation of analog functions, which are however essential to acquire data from sensors, thus enabling the interactions of IoT nodes with the surrounding environment, is nowadays the real bottleneck and the most serious concern and limiting factor for the further development of IoT applications.
In the foreseeable future, the planned device scaling and voltage reduction down to near threshold (e.g. 0.4-0.5V) makes the design of analog circuits extremely hard, in view of the degradation of signal-to-noise ratio, matching and linearity. Despite of device shrinking, traditional low-voltages analog circuits do not really scale down in size, and occupy a more and more relevant percentage (i.e., cost) of the die area.
In this scenario, the proposed research activity is intended to substantially enhance the scalability of analog blocks with technology and voltage by re-thinking analog functions in ICs in digital terms. In a new cross-domain approach, design and testing methodologies from the digital world will be extended and frontier design concepts like near-threshold operation further exploited.
The effectiveness of the proposed approach will be verified and validated on IC demonstrators and with reference to a full SoC for wearable electronics applications in the development of novel IoT solutions.
Phenolic Characterization and Geographical Classification of Commercial Extra Virgin Olive Oils Produced in Turkey

The aim of this research was to characterize the extra virgin olive oil samples from different locations in the Aegean coastal area of Turkey in terms of their phenolic compositions for two consecutive years to show the classification of oil samples with respect to harvest year and geography. Forty seven commercial olive oil samples were analyzed with HPLC–DAD, and 17 phenolic compounds were quantified. Hydroxytyrosol, tyrosol, vanillic acid, p-coumaric acid, ferulic acid, cinnamic acid, luteolin and apigenin were the characteristic phenols observed in all oil samples for two harvest years. Syringic acid, vanillin and m-coumaric acid were the phenolic compounds appeared in the olive oil depending on the harvest year. Partial least square-discriminant analysis (PLS-DA) of data revealed that oils from the north Aegean and south Aegean areas had different phenolic profiles. The phenolic compounds, which played significant roles in the discrimination of the olive oils, were tyrosol, oleuropein aglycon, cinnamic acid, apigenin and hydroxytyrosol to tyrosol ratio. The Aegean coastal region is the largest olive oil producer and exporter of Turkey. This study shows that the olive oils from different parts of the region have their own defining characteristics that can be used in the authentication studies and geographical labeling of Turkish olive oils.

Design, optimization and evaluation of glipizide solid self-nanoemulsifying drug delivery for enhanced solubility and dissolution

A solid self-nanoemulsifying drug-delivery system (solid SNEDDS) has been explored to improve the solubility and dissolution profile of glipizide. SNEDDS preconcentrate was systematically optimized using a circumscribed central composite design by varying Captex 355 (Oil), Solutol HS15 (Surfactant) and Imwitor 988 (Co-surfactant). The optimized SNEDDS preconcentrate consisted of Captex 355 (30% w/w), Solutol HS15 (45% w/w) and Imwitor 988 (25% w/w). The saturation solubility (SS) of glipizide in optimized SNEDDS preconcentrate was found to be 45.12 ± 1.36 mg/ml, indicating an improvement (1367 times) of glipizide solubility as compared to its aqueous solubility (0.033 ± 0.0021 mg/ml). At 90% SS, glipizide was loaded to the optimized SNEDDS. In-vitro dilution of liquid SNEDDS resulted in a nanoemulsion with a mean droplet size of 29.4 nm. TEM studies of diluted liquid SNEDDS confirmed the uniform shape and size of the globules. The liquid SNEDDS was adsorbed onto calcium carbonate and talc to form solid SNEDDS. PXRD, DSC, and SEM results indicated that, the presence of glipizide as an amorphous and as a molecular dispersion state within solid SNEDDS. Glipizide dissolution improved significantly (p < 0.001) from the solid SNEDDS (∼100% in 15 min) as compared to the pure drug (18.37%) and commercial product (65.82) respectively.
