The bottle gourd genome provides insights into Cucurbitaceae evolution and facilitates mapping of a Papaya ring spot virus resistance locus
Venue: The Plant journal for cell and molecular biology
Year: 2017

Bottle gourd (Lagenaria siceraria) is an important vegetable crop as well as a rootstock for other cucurbit crops. In this study, we report a high quality 313.4 Mb genome sequence of a bottle gourd inbred line, USVL1VR Ls, with a scaffold N50 of 8.7 Mb and the longest of 19.0 Mb. About 98.3% of the assembled scaffolds are anchored to the 11 pseudomolecules. Our comparative genomic analysis identifies chromosome level syntenic relationships between bottle gourd and other cucurbits, as well as lineage specific gene family expansions in bottle gourd. We reconstructed the genome of the most recent common ancestor of Cucurbitaceae, which revealed that the ancestral Cucurbitaceae karyotypes consisted of 12 protochromosomes with 18 534 protogenes. The 12 protochromosomes are largely retained in the modern melon genome, while have undergone different degrees of shuffling events in other investigated cucurbit genomes. The 11 bottle gourd chromosomes derive from the ancestral Cucurbitaceae karyotypes followed by 19 chromosomal fissions and 20 fusions. The bottle gourd genome sequence has facilitated the mapping of a dominant monogenic locus, Prs, conferring Papaya ring spot virus (PRSV) resistance in bottle gourd, to a 317.8 kb region on chromosome 1. We have developed a cleaved amplified polymorphic sequence (CAPS) marker tightly linked to the Prs locus and demonstrated its potential application in marker assisted selection of PRSV resistance in bottle gourd. This study provides insights into the paleohistory of Cucurbitaceae genome evolution, and the high quality genome sequence of bottle gourd provides a useful resource for plant comparative genomics studies and cucurbit improvement.
Structural, microstructural and multiferroic properties of BiFeO3 CoFe2O4 composites
Venue: Journal of Materials Science: Materials in Electronics
Year: 2018

BiFeO3 CoFe2O4 composites were successfully prepared via conventional solid state method. Powder X ray diffraction confirmed the presence of both perovskite BiFeO3 (BFO) and spinel CoFe2O4 (CFO) phases and rhombohedral structure due to splitting in major peaks in the composites. Further insight into the microstructural and morphological properties of the composites was provided by Raman spectra, Fourier Transform Infrared Spectroscopy and Field Emission Scanning Electron Microscopy along with EDX analysis. Magnetic and electrical response of the composites has been studied exhaustively to comprehend their multiferroic properties. Magnetization study (magnetization vs. magnetic field) confirmed the high saturation magnetization in composites with a low value of coercivity at room temperature. The maximum saturation magnetization (0.3902 emu/g) was achieved in BFO 30%CFO. Ferroelectric polarization (polarization vs. electric field) loop measurements confirmed the low electrical leakage current in the composites. The temperature dependent dielectric response of the composites suggested existence of magnetoelectric coupling between the ferroelectric and ferromagnetic orders in the vicinity of antiferromagnetic paramagnetic transition temperature of BFO. The decrease in dielectric loss with an increase in CFO content in the composites also validated the similar results as observed in polarization versus electric field measurements. The Impedance Spectroscopy at room temperature revealed the non Debye behavior and high resistivity of the composites.
Enzymatic degradation of azo dyes using three macrophyte species: Arundo donax, Typha angustifolia and Phragmites australis
Year: 2014

AbstractThe aim of this study was to investigate the potential role of three macrophyte species (Arundo donax, Typha angustifolia and Phragmites australis) for degradation of azo dyes. Activities of peroxidases enzymes involved in plant protection against stress were tested for dye decolourization. In order to conduct the enzyme activity assay, the fresh extract was obtained from crude extracts of leaves. The oxidation capability of peroxidase (POD) on direct azo dyes (amaranth and amido black) was investigated and found to be an effective treatment methodology. The performance of peroxidase was evaluated in soluble and free form in the presence of H2O2. The oxidation was tested as a function of peroxidase at constant POD activity. Parameters such as temperature (5 70degC) concentration of H2O2 (0 1000 mM/L) pH (4 10) dye concentration (0.002 1 mM/L) and enzyme amount (5 20 mL) were studied. Results show that P. australis, leaves contained the highest peroxidase activity. The dye decolourization is about.
Algorithm for optimal mode scheduling in switched mode hybrid dynamical systems
Venue: 2010 IEEE 26 th Convention of Electrical and Electronics Engineers in Israel
Year: 2010

This paper proposes an algorithm for optimal mode scheduling in switched mode hybrid dynamical systems. The variable parameter consists of the sequence of modes and the switching times between them, and the cost criterion has the form of an integral of a suitable cost function over the state trajectory. The sequencing variable is discrete and hence the problem cannot be solved by standard optimal control techniques. Furthermore, as it is common in optimal scheduling, the problem may be NP hard. In order to ensure computability we replace global optimality by a suitable notion of suboptimality that reflects local minima of schedules. We propose an effective algorithm, prove its convergence, and demonstrate it on an example.
Mental adjustment to cancer and its relation to anxiety, depression, HRQL and survival in patients with laryngeal cancer A longitudinal study
Venue: BMC Cancer
Year: 2010

BackgroundUsing a longitudinal design, aim of this study was to investigate the relation between mental adjustment to cancer and anxiety, depression, health related quality of life (HRQL) and survival in patients treated for laryngeal cancer.Methods95 patients with Tis T4 laryngeal cancer were assessed at one and 12 months after start of treatment, respectively, using the Mini Mental Adjustment to Cancer Scale (Mini MAC) the European Organisation for Research and Treatment of Cancer (EORTC) Study Group on Quality of Life core questionnaire (EORTC QLQ C30) supplemented with the Head and Neck cancer module (QLQ H&N35) and the Hospital Anxiety and Depression (HAD) Scale. For survival analyses patients were followed up for a median time of 4.22 years from inclusion.ResultsThe most commonly used adjustment response at both occasions was Fighting Spirit. The use of adjustment responses was relatively stable over time. Correlation analyses showed that patients using Helpless Hopeless and Anxious Preoccupation responses reported more anxiety and depression, as well as decreased HRQL. Tumour site and stage showed no effect on adjustment response. Survival analysis indicated that use of a Helpless Hopeless response was related to poorer survival (HR 1.17, p 0.001).ConclusionThe relation between adjustment responses Helpless Hopeless and Anxious Preoccupation and anxiety, depression, HRQL and possibly poorer survival indicate that assessment of mental adjustment should be considered when planning treatment and rehabilitation in laryngeal cancer patients.
IMPROVING A GREEDY DNA MOTIF SEARCH USING A MULTIPLE GENOMIC SELF ADAPTATING GENETIC ALGORITHM
Year: 2007

We consider the problem of combining a greedy motif search algorithm [16] with a self adapting genetic algorithm employing multiple genomic representations in order to find high scoring substring patterns of size k in a set of t DNA sequences of size n thus improving the results of a stand alone greedy motif search. We propose using multiple genomic (redundant) representations in a self adapting genetic algorithm (GA) employing various codes with different locality properties. These encoding schemes insure feasibility after performing the operations of crossover and mutation and also ensure the feasibility of the initial randomly generated population (i.e. generation 0) The GAs applied in solving this problem employ non locality or locality representations when appropriate (i.e. the GA adapts to its current search needs) which makes the GAs more efficient [15]
Gap Bridging Ability in Laser Beam Welding of Thin Aluminum Sheets
Year: 2014

The applicability of laser welding processes with its specific advantages, such as low distortion or production efficiency, is often limited when joining thin walled aluminum components due to small gap bridging ability. To overcomethis limit, a novel approach is presented using filler wire and a highly focused laser beam oscillation transverse to the welding direction. In the present work, the process development for welding in butt joint configuration is shown. For this purpose, the influence of the welding speed, wire feed speed and beam oscillation parameters on wire melting behavior and on the welding result is presented. A process window for joining thin sheet material of 1 mm thickness with 1 mm joint gap is shown, and allowable tolerances for laser, wire and gap misalignment are investigated. Furthermore, the reached gap bridging ability of 1.9 mm for a constant gapand 3.15 mm for an opening gap configuration is shown in dependence of the utilized aluminum alloys.
Research Article Effects of Shape and Technology of Installation on the Bearing Capacity of Pile Foundations in Layered Soil
Year: 2015

Among other factors, which influence the bearing capacity of piles, the shape of its external configuration, as well the installation technique employed during construction, also play major roles. This paper presents the results of recent experimental investigation on effects of shape and technology of installation on the bearing capacity of pile foundations. The results from both laboratory and field investigations conducted on modeled prototype test piles of cylindrical, prismatic (square) and tapered conical sections are presented in this study. The piles were installed by driving (hammering and vibration) and boring techniques. The results of influence of installation methods, show bearing capacity increments of 10% in bored piles, 20 22% in hammered driven piles, and 20 30% in vibrated driven piles. The bearing capacity of tapered conical piles is 1.5 2 times higher than prismatic (square) piles and 2 3 times higher than cylindrical piles respectively. Tapered conical piles have higher bearing capacity in fairly homogenous soils, (whether soft or stronger) In sandy and silty sand soils, especially where fine sand overlaid a stronger coarse sand layers, driven piles (hammer or vibration) have higher bearing capacity than bored piles, whereas the latter have higher bearing capacity where soft fine sand sandwiched between stronger coarse sand layers. Cylindrical piles installed by boring method have higher bearing capacity in sandy soils than prismatic pile installed by driven, but the latter gave higher bearing values in layered soil with thicker stiff silty clay above sandy layers.
Histopathology of Alcohol Related Liver Diseases.
Venue: Clinics in liver disease
Year: 2019

Excessive alcohol consumption can lead to a spectrum of liver histopathology, including steatosis, steatohepatitis, foamy degeneration, fatty liver with cholestasis, and cirrhosis. Although variability in sampling and pathologist interpretation are of some concern, liver biopsy remains the gold standard for distinguishing between steatohepatitis and noninflammatory histologic patterns of injury that can also cause the clinical syndrome of alcohol related hepatitis. Liver biopsy is not routinely recommended to ascertain a diagnosis of alcohol related liver disease in patients with an uncertain alcohol history, because the histologic features of alcohol related liver diseases can be found in other diseases, including nonalcoholic steatohepatitis and drug induced liver injury.
Strategic relationships between boundary spanning functions: Aligning customer relationship management with supplier relationship management
Year: 2009

This review focuses on the potential impact of enhanced strategic relationships between the boundary spanning functions in supplier organizations. Specifically, the concern is with alignment between the organizational groups managing: marketing, sales and strategic account management; purchasing and supply strategy; and, collaborations and external partnerships. The topic is framed by the organizational evolution being driven by market change, and the search for superior innovation capabilities and business agility. These changes bring new challenges in cross boundary integration and managing complex market networks. The logic is that strategic external relationships (with customers, supplier and partners) should be mirrored in strategic internal relationships (between the functions with lead responsibilities for managing relationships with customers, supplier and partners) Approaches to enhancing this capability include process management, internal partnering strategies and internal marketing activities. The discussion identifies a number of implications for practice and new research directions.
Chess as a Powerful Eduacational Tool for Successful People
Year: 2019

In accordance with the challenges brought out by modern times, it is necessary to adapt to the new circumstances in the field of education. Classical education programs do not provide enough opportunities for individual development, so recently there are many noticeable attempts to refresh existing programs through the introduction of new educational techniques with the aim of better knowledge acquisition in school and preschool age. One of those new techniques is the use of chess, which has proven to be an excellent educational tool through its beneficial factors. Important benefits can be divided into cognitive elements: concentration, memory and logical thinking, as essential skills for the development of each individual; critical thinking factors: improving the ability to assess strengths and weaknesses, establishing value judgments and making decision; and improving creativity through problem solving. Along with these main factors, there are causal connections with better results in mathematics, improvements in attitude and general behavior, as well as in literacy. What is actually the main advantage of using chess as a formal or informal learning tool in education is that all these benefits can be gained while playing, which is exceptional value in preschool and school age! It is important to emphasize that the chess program also allows to teachers certain freedom for their own creative expression in program implementation in order to raise the attention of children. The aim of this paper is to present in more detail the process of introducing chess as possible education tool in Croatia (and applicable in other countries) Advantages achieved in correlation to the existing programs should be point out, as well as the skills acquired through contact with chess that become one of the most important skills with which individuals can compete in a competitive labor market and in their further life roles, even at the highest management levels.
Efficient Angle of Arrival Estimation of Lens Antenna Arrays for Wireless Information and Power Transfer
Venue: IEEE Journal on Selected Areas in Communications
Year: 2019

Antenna design and angle of arrival (AoA) estimation are critical to the efficiency of wireless information and power transfer. The AoA estimation is challenging for energy efficient lens antenna arrays (LAAs) due to discrete sets of fixed discrete Fourier transform (DFT) beams. This paper presents a novel fast and accurate approach for the AoA estimation of LAAs. The key idea is that we prove the two differential outputs of three adjacent lens beams, referred to as "DFT beam differences (DBDs)" that are the strongest at the two sides of an AoA. They are easy to identify and robust to noises, and their powers are proved to provide an accurate estimate of the AoA. Another important aspect is a new beam synthesis technique which produces different beam widths based on DFT beams and practical 1 bit phase shifts in real time. As a result, the angular region containing the AoA can exponentially narrow down, and the two strongest DBDs can be quickly identified. The proposed approach can operate in coupling with successive interference cancellation to estimate the AoAs of multiple paths. Simulations show that the proposed approach is able to outperform the state of the art by orders of magnitude in terms of accuracy. The power transfer efficiency can be dramatically improved.
The Impact of Non Photosynthetic Vegetation on LAI Estimation by NDVI in Mixed Grassland
Venue: Remote. Sens.
Year: 2020

Leaf area index (LAI) is widely used for algorithms and modelling in the field of ecology and land surface processes. At a global scale, normalized difference vegetation index (NDVI) products generated by different remote sensing satellites, have provided more than 40 years of time series data for LAI estimation. NDVI saturation issues are reported in agriculture and forest ecosystems at high LAI values, creating a challenge when using NDVI to estimate LAI. However, NDVI saturation is not reported on LAI estimation in grasslands. Previous research implies that non photosynthetic vegetation (NPV) reduces the accuracy of LAI estimation from NDVI and other vegetation indices. A question arises: is the absence of NDVI saturation in grasslands a result of low LAI value, or is it caused by NPV? This study aims to explore whether there is an NDVI saturation issue in mixed grassland, and how NPV may influence LAI estimation by NDVI. In addition, in situ measured plant area index (PAI) by sensors that detect light interception through the vegetation canopy (e.g. Li cor LAI 2000) the most widely used field LAI collection method, might create bias in LAI estimation or validation using NDVI. Thus, this study also aims to quantify the contribution of green vegetation (GV) and NPV on in situ measured PAI. The results indicate that NDVI saturation (using the portion of NDVI only contributed by GV) exists in grassland at high LAI (LAI threshold is much lower than that reported for other ecosystems in the literature) and that the presence of NPV can override the saturation effects of NDVI used to estimate green LAI. The results also show that GV and NPV in mixed grassland explain, respectively, the 60.33% and 39.67% variation of in situ measured PAI by LAI 2000.
Ramelteon for the treatment of insomnia in adults: a systematic review and meta analysis.
Venue: Sleep medicine
Year: 2014

Ramelteon is the first selective melatonin receptor agonist and currently is approved in the United States and Japan for the treatment of insomnia. Our meta analysis assessed the efficacy and safety of ramelteon for the treatment of insomnia in adults. We included both published and unpublished data from randomized placebo controlled trials evaluating the efficacy of ramelteon in adults with insomnia in the analysis. Our primary outcomes were sleep quality, subjective sleep latency (sSL) and subjective total sleep time (sTST) Secondary outcomes included latency to persistent sleep (LPS) total sleep time (TST) sleep efficiency (SE) proportion of rapid eye movement (REM) sleep, wakefulness after sleep onset (WASO) subjective WASO, number of nighttime awakenings (NAW) subjective NAW, and adverse events. Thirteen trials involving 5812 patients with insomnia or insomnia symptoms with a mean study duration of 38 days were pooled. Ramelteon was associated with reduced sSL (weighted mean difference [WMD] 4.30 min [95% confidence interval {CI} 7.01 to 1.58] and improved sleep quality (standardized mean differences, 0.074 [95% CI, 0.13 to 0.02] but was not associated with increased sTST. Ramelteon also was associated with improvement in LPS, SE, and TST. The only significant adverse event was somnolence. Short term use of ramelteon was associated with improvement in some sleep parameters in patients with insomnia, but its clinical impact is small. Long term trials are needed before solid conclusions can be established.
DIURNAL AND SPATIAL VARIATIONS OF RADON CONCENTRATION AND ITS INFLUENCE ON IONIZATION OF AIR
Year: 2020

The most abundant and efficient source of air ionization in the lower layer of the atmosphere is radon. As an alpha emitter, radon plays a crucial role in the earth's atmospheric electricity. Besides the physical, radon and ions have a significant biological role concerning human health: radon is a health hazard while the ions are beneficial ingredients of the air we breathe. In this study, we examined the dynamics of radon and air ions diurnal change in houses with different floor and windows insulations. Measurements were made using continual radon monitor Rad 7 and air ion counter CDI 06. Diurnal and spatial variations of both atmospheric constituents are mutually related and dependent mostly on radon exhalation potential, meteorological parameters, aerosol concentration and formation of the temperature inversion layer. Indoor concentrations are related to the potential for accumulation of radon that is coming from the ground beneath the foundation and also influenced by external radon concentration that is diffusing through the walls, doors, and windows. Level of diffusion is depending on insulation. The difference in the paths by which radon enters the home can be seen by analyzing changes during diurnal continuous measurements.
Facial mimicry, facial emotion recognition and alexithymia in post traumatic stress disorder.
Venue: Behaviour research and therapy
Year: 2019

Individuals with post traumatic stress disorder (PTSD) show abnormalities in higher order emotional processes, including emotion regulation and recognition. However, automatic facial responses to observed facial emotion (facial mimicry) has not yet been investigated in PTSD. Furthermore, whereas deficits in facial emotion recognition have been reported, little is known about contributing factors. We thus investigated facial mimicry and potential effects of alexithymia and expressive suppression on facial emotion recognition in PTSD. Thirty eight PTSD participants, 43 traumatized and 33 non traumatized healthy controls completed questionnaires assessing alexithymia and expressive suppression. Facial electromyography was measured from the muscles zygomaticus major and corrugator supercilii during a facial emotion recognition task. Corrugator activity was increased in response to negative emotional expressions compared to zygomaticus activity and vice versa for positive emotions, but no significant group differences emerged. Individuals with PTSD reported greater expressive suppression and alexithymia than controls, but only levels of alexithymia predicted lower recognition of negative facial expressions. While automatic facial responses to observed facial emotion seem to be intact in PTSD, alexithymia, but not expressive suppression, plays an important role in facial emotion recognition of negative emotions. If replicated, future research should evaluate whether successful interventions for alexithymia improve facial emotion recognition abilities.
In hand forward and inverse kinematics with rolling contact
Venue: Robotica
Year: 2017

Robotic hands use rolling contact to manipulate a grasped object to a desired location, even when the finger and the palm linkage mechanisms lack degrees of freedom. This paper presents a systematic approach to the forward and inverse kinematics of in hand manipulation. The moving frame method in differential geometry is integrated into the product of exponential formula to establish a pure geometric framework of the kinematics of a robot hand. The forward and inverse kinematics of a multifingered hand are obtained in terms of the joint rates and contact trajectories. A two fingered planar robot hand and a three fingered spatial robot hand are used to demonstrate the proposed approach. The proposed formulation amounts to solving a univariate polynomial, providing an alternative to the existing ones that require numerical integration.
