Object-Proposal Evaluation Protocol is ‘Gameable’ (2016)

Object proposals have quickly become the de-facto preprocessing step in a number of vision pipelines (for object detection, object discovery, and other tasks). Their performance is usually evaluated on partially annotated datasets. In this paper, we argue that the choice of using a partially annotated dataset for evaluation of object proposals is problematic - as we demonstrate via a thought experiment, the evaluation protocol is 'gameable', in the sense that progress under this protocol does not necessarily correspond to a "better" category independent object proposal algorithm. To alleviate this problem, we: (1) Introduce a nearly-fully annotated version of PASCAL VOC dataset, which serves as a test-bed to check if object proposal techniques are overfitting to a particular list of categories. (2) Perform an exhaustive evaluation of object proposal methods on our introduced nearly-fully annotated PASCAL dataset and perform cross-dataset generalization experiments, and (3) Introduce a diagnostic experiment to detect the bias capacity in an object proposal algorithm. This tool circumvents the need to collect a densely annotated dataset, which can be expensive and cumbersome to collect. Finally, we have released an easy-to-use toolbox which combines various publicly available implementations of object proposal algorithms which standardizes the proposal generation and evaluation so that new methods can be added and evaluated on different datasets. We hope that the results presented in the paper will motivate the community to test the category independence of various object proposal methods by carefully choosing the evaluation protocol.

On Farm Agronomic and First Environmental Evaluation of Oil Crops for Sustainable Bioenergy Chains (2009)

Energy crops, and in particular oil crops, could be an important occasion for developing new non food production rows for a new multi-functional agriculture in Italy. In this view, the use of local biomass is a fundamental starting point for the development of a virtuous energy chain that should pursue not only agricultural profitability, but also chain sustainability and that is less dependent on the global market, characterized by instability in terms of biomass availability and price. From this perspective, particular attention must be paid to crop choice on the basis of its rusticity and of its adaptability to local growing conditions and to low input cropping systems. In this context, alike woody and herbaceous biomasses, oil crops such as sunflower and rapeseed should be able to support local agricultural bioenergy chain in Italy. In addition, in a local bioenergy chain, the role of the farmers should not be limited just to grain production; but also grain processing should be performed at farm or consortium level in oilseed extraction plants well proportioned to the cropped surface. In this way, by means of a simple power generator, farmer could thus produce its own thermal and electric energy from the oil, maximizing his profit. This objective could also be achieved through the exploitation of the total biomass, including crop residues and defatted seed meals, that may be considered as fundamental additional economic and/or environmental benefits of the chain. This paper reports some results of three-years on-farm experiments on oil crop chain carried out in the framework of &ldquo;Bioenergie&rdquo; project, that was focused to enhance farmers awareness of these criteria and to the feasibility at open field scale of low-input cultivation of rapeseed, sunflower and Brassica carinata in seven Italian regions. In several on-farm experiences, these crops produced more than 800 kg ha-1 of oil with good energy properties. Defatted seed meals could be interesting as organic fertilizers and, in the case of B. carinata, as a biofumigant amendment that could offer a total or partial alternative to some chemicals in agriculture. Furthermore, biomass soil incorporation could contribute to C sequestration, catching CO2 from atmosphere and sinking a part in soil as stable humus. Finally, four different open field experiences carried out again in the second year of the project, have been analysed in order to evaluate their energy and greenhouse gasses balance after cultivation phase.
Quantum algorithm for simulating molecular vibrational excitations (2020)

The excitation of vibrational modes in molecules affects the outcome of chemical reactions, for example by providing molecules with sufficient energy to overcome activation barriers. In this work, we introduce a quantum algorithm for simulating molecular vibrational excitations during vibronic transitions. We discuss how a special-purpose quantum computer can be programmed with molecular data to optimize a vibronic process such that desired modes get excited during the transition. We investigate the effect of such excitations on selective bond dissociation in pyrrole and butane during photochemical and mechanochemical vibronic transitions. The results are discussed with respect to experimental observations and classical simulations. We also introduce quantum-inspired classical algorithms for simulating molecular vibrational excitations in special cases where only a limited number of modes are of interest.

Interstitial microwave hyperthermia applicators having submillimetre diameters (1990)

Using microscopic techniques we have fabricated interstitial hyperthermia applicators having diameters of 0.20, 0.33 and 0.58 mm, which will fit through catheters of 30, 26 and 22 gauge, respectively. Existing commercial applicators having a diameter of 1.1 mm required 17 gauge (or larger) catheters. Our new applicators, which operate at 915 MHz, are a smaller version of a design used by others. We have characterized our applicators by determining the energy deposition patterns (SAR) in muscle-simulating phantoms. These patterns were determined by measuring the electric field intensity using a miniature implantable isotropic probe having a diameter of 3 mm. Contours of the SAR data for our applicators, as well as a larger commercial applicator, show that all of these applicators exhibit similar heating patterns. Test results suggest that the durability and power handling capability of our submillimetre applicators are adequate for use in patients. Our new applicators should be useful in the percutaneous treatment of deep-seated tumours, intraoperative treatments, and also permit intraluminal or intravascular access to tumours.
Use of quantitative shotgun proteomics to identify fibronectin 1 as a potential plasma biomarker for clear cell carcinoma of the kidney (2012)

The FN1 is considered to be a promising biomarker candidate for clear cell RCC. Furthermore, AlphaLISA is an alternate to the conventional enzyme-linked immunosorbent assay and should prove useful for the rapid validation of biomarker candidates.
Assessment of thick film YBCO for flux transformer and magnetic screening applications (1993)

Measurements on the flux creep properties of a series of thick-film YBCO tubes and rings that have been processed at a range of different temperatures are reported, and their potential for use in large-area flux transformers and shields for superconducting quantum interference device (SQUID) magnetometers is considered. It is found that films showing flux creep rates adequate for flux transformer or low-field ( approximately 100- mu T) magnetic shielding applications can be made without recourse to special doping or heat treatment techniques. Application of flux creep theory to the data and observations of the microstructure in similar films implies that the scale over which the supercurrents are flowing is on the order of tens of mm and that this would place a lower limit on fabrication accuracy. For screening the earth's magnetic field, the films reported here would be adequate; for higher fields, thicker or multiple shields may by required.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Assessment of Reproductive Frequency in the European Pond Turtle ( Emys orbicularis ) Using Manual Palpation, Ultrasonography, and Radiography (2013)

Assessment of reproductive status in female European pond turtles has been investigated with three different methods. The comparative analysis of the obtained results revealed that all three methods are important in determining female reproductive status. Degree of efficiency is however different among them. Manual palpation is the easiest to perform but lacks of precision regarding determination of clutch and egg size; radiography is the most efficient in determining clutch and egg size but it is applicable only when egg shells are calcified; ultrasonography is almost certainly the most precise technique to understand if females are reproductive, while it can not have a complete insight over all the oviductal or follicular eggs. We strongly recommend the use of both three methods when studying reproductive plasticity and frequency in fresh water turtles.

PROSTACYCLIN‐DEPENDENT ACTIVATION OF ADENYLATE CYCLASE IN A NEURONAL SOMATIC CELL HYBRID: PROSTANOID STRUCTURE‐ACTIVITY RELATIONSHIPS (1980)

1 Prostacyclin activates adenylate cyclase of the NCB-20 neuronal hybrid cell line. 2 There is a guanosine 5'-triphosphate requirement for the activation of adenylate cyclase by 5,6 beta-dihydroprostacyclin (a stable analogue of prostacyclin). 3 Steady-state kinetic analysis of the activation of adenylate cyclase by 5,6 beta-dihydroprostacyclin suggests a simple non-cooperative bimolecular interaction between the ligand and single receptor population. 4 Structure-activity relationships of selected prostanoids elucidated certain functional requirements for activation of adenylate cyclase.
Superconductivity in SrB3C3 clathrate (2017)

We predict superconductivity for the carbon-boron clathrate SrB3C3 at 27-43 K for Coulomb pseudopotential (mu*) values between 0.17 and 0.10 using first-principles calculations with conventional electron-phonon coupling. Electrical transport measurements, facilitated by a novel in situ experimental design compatible with extreme synthesis conditions (&gt;3000 K at 50 GPa), show non-hysteretic resistivity drops that track the calculated magnitude and pressure dependence of superconductivity for mu*=0.15, and transport measurements collected under applied magnetic fields confirm superconductivity with an onset Tc of approximately 20 K at 40 GPa. Carbon-based clathrates thus represent a new class of superconductors similar to other covalent metals like MgB2 and doped fullerenes. Carbon clathrates share structures similar to superconducting superhydrides, but covalent C-B bonds allow metastable persistence at ambient conditions.

Effect of pre- and posttreatment of losartan in feline model ofmyocardial ischemic-reperfusion injury (2004)

This study investigated the differential effect of losartan, an AT1 receptor blocker, when administered in pre- and postischemic phases, on the biochemical, hemodynamic and oxidative stress associated with regional ischemic-reperfusion injury in cat. Losartan (5 microg/kg/min) or normal saline was administered intravenously in open chest barbiturate anesthetized cats, 15 min before and 10 min after the occlusion of the left anterior descending (LAD) coronary artery. The LAD was occluded for 15 min followed by 60 min reperfusion. In the saline treated group, there was significant depression of hemodynamic functions, i.e., mean arterial pressure (MAP), heart rate (HR), left ventricular end diastolic pressure (LVEDP) and left ventricular (LV) peak (+/-) dP/dt, along with depletion of adenosine triphosphate (ATP) of the affected myocardium. Oxidative stress during reperfusion injury was evidenced by significant increase in plasma thiobarbituric acid reactive substances (TBARS) accompanied by significant reduction in myocardial superoxide dismutase (SOD) activities. In both treatment groups, losartan caused recovery of all the hemodynamic parameters and repletion of ATP along with no significant change in plasma TBARS and myocardial SOD activity. There was no effect on catalase activity. Results from the study suggest that the effects of pre- and posttreatment of losartan are comparable in functional recovery of the heart from ischemic-reperfusion injury.
Dynamic axial stabilization of counter-propagating beam-traps with feedback control (2010)

Optical trapping in a counter-propagating (CP) beam-geometry provides unique advantages in terms of working distance, aberration requirements and intensity hotspots. However, its axial performance is governed by the wave propagation of the opposing beams, which can limit the practical geometries. Here we propose a dynamic method for controlling axial forces to overcome this constraint. The technique uses computer-vision object tracking of the axial position, in conjunction with software-based feedback, for dynamically stabilizing the axial forces. We present proof-of-concept experiments showing real-time rapid repositioning coupled with a strongly enhanced axial trapping for a plurality of particles of varying sizes. We also demonstrate the technique's adaptability for real-time reconfigurable feedback-trapping of a dynamically growing structure that mimics a continuously dividing cell colony. Advanced implementation of this feedback-driven approach can help make CP-trapping resistant to a host of perturbations such as laser fluctuations, mechanical vibrations and other distortions emphasizing its experimental versatility.

Electrolyte Changes in Ileal Contents and in Feces during Restriction of Dietary Sodium with and without the Administration of Cation-Exchange Resin (1955)

Sodium and potassium levels of the contents of the terminal ileum and feces were determined for four dogs at different dietary sodium intakes, both before and during administration of a carboxylic cation-exchange resin. With restriction of dietary sodium, there was more sodium bound by the resin in the terminal ileum than was provided by the diet. There was considerable conservation of sodium in the upper gastrointestinal tract, but the colon always absorbed a major part of the sodium presented to it. During resin administration with very low sodium diets there was more sodium in the feces than in the diets.

Acute Cyanide Poisoning Complicated by Lactic Acidosis and Pulmonary Edema (1977)

Massive cyanide poisoning occurred in a 21-year-old man who had ingested 600 mg of potassium cyanide. The clinical course was marked by acute pulmonary edema and lactic acidosis. Because the poison was unidentified until nine hours after ingestion, the patient received only supportive treatment which included diuresis, oxygen, bicarbonate, and assisted ventilation. A review of the literature shows that many case reports are poorly documented and do not provide a firm basis for evaluating therapy. To our knowledge, only four patients, including ours, have had blood levels of cyanide measured. In the absence of a suitable history, diagnosis of cyanide poisoning is difficult. A simple chemical test which can be performed on gastric aspirate is available. Hydroxocobalamin may be used as a nontoxic specific antidote. Nonspecific supportive therapy is of great importance.
Optical Properties of Atomically Thin Layered Transition Metal Dichalchogenide (2015)

Semiconducting transition metal dichalcogenides (TMDs) called as "beyond graphene" will open new research fields of atomically thin layered materials. The optical properties of monolayer TMDs are dominated by strongly correlated bound states of electron–hole (excitons) and two-electrons–hole (charged exciton) due to the enhanced Coulomb interactions confined in atomically thin layered materials. Here, we review novel optical properties related to carriers, excitons, and charged excitons in monolayer TMDs, including features of optical absorption, photoluminescence (PL) spectra, control of PL by chemical doping, and nonlinear optical response, which have been studied by continuous-wave and time-resolved optical spectroscopy. The understanding of optical phenomena related to optically excited states including carriers, excitons, and charged excitons (trions) is critical for the development of future optoelectronic devices using TMDs.
