description: Somatic sequencing of cancers has produced new insight into tumorigenesis, tumor heterogeneity, and disease progression, but the vast majority of genetic events identified are of indeterminate clinical significance. Here we describe a NextGen sequencing approach to fully analyze 248 genes, including all those of known clinical significance in melanoma. This strategy features solution capture of DNA followed by multiplexed, high-throughput sequencing, and was evaluated in 31 melanoma cell lines and 18 tumor tissues from patients with metastatic melanoma. Mutations in melanoma cell lines correlated with their sensitivity to corresponding small molecule inhibitors, confirming, for example, lapatinib sensitivity in ERBB4 mutant lines and identifying a novel activating mutation of BRAF. The latter event would not have been identified by clinical sequencing and was associated with responsiveness to a BRAF kinase inhibitor. This approach identified focal copy number changes of PTEN not found by standard methods, such as comparative genomic hybridization (CGH). Actionable mutations were found in 89% of the tumor tissues analyzed, 56% of which would not be identified by standard-of-care approaches. This work shows that targeted sequencing is an attractive approach for clinical use in melanoma.

description: Soil fauna is a key control of the decomposition rate of leaf litter, yet its interactions with litter quality and the soil environment remain elusive. We conducted a litter decomposition experiment across different topographic levels within the landscape replicated in two rainforest sites providing natural gradients in soil fertility to test the hypothesis that low nutrient availability in litter and soil increases the strength of fauna control over litter decomposition. We crossed these data with a large dataset of 44 variables characterizing the biotic and abiotic microenvironment of each sampling point and found that microbe-driven Carbon (C) and Nitrogen (N) losses from leaf litter were 10.1 and 17.9% lower, respectively, in the nutrient-poorest site, but this among-site difference was equalized when meso- and macrofauna had access to the litterbags. Further, on average, soil fauna enhanced the rate of litter decomposition by 22.6%, and this contribution consistently increased as nutrient availability in the microenvironment declined. Our results indicate that nutrient scarcity increases the importance of soil fauna on C and N cycling in tropical rainforests. Further, soil fauna is able to equalize differences in microbial decomposition potential, thus buffering to a remarkable extent nutrient shortages at an ecosystem level.

description: Many mosses of the family Splachnaceae are entomophilous and rely on flies for spore dispersal. Splachnum ampullaceum produces a yellow- or pink-coloured hypophysis that releases volatile compounds, attracting flies to the mature moss. The biosynthetic sources of the visual and aromatic cues within the hypophysis have not been identified, and may be either symbiotic cyanobacteria or chromoplasts that break down lipids into volatile compounds. Here, we used transmission electron microscopy and gas chromatography-mass spectrometry (GC-MS) to investigate the sources of these attractants, focusing on different tissues and stages of maturation. Microscopy revealed an abundance of plastids within the hypophysis, while no symbiotic bacteria were observed. During plant maturation, plastids differentiated from amyloplasts with large starch granules to photosynthetic chloroplasts and finally to chromoplasts with lipid accumulations. We used GC-MS to identify over 50 volatile organic compounds from mature sporophytes including short-chain oxygenated compounds, unsaturated irregular terpenoids, fatty acid-derived 6- and 8-carbon alcohols and ketones, and the aromatic compounds acetophenone and p-cresol. The hypophysis showed localised production of pungent volatiles, mainly short-chain fermentation compounds and p-cresol. Some of these volatiles have been shown to be produced from lipid oxidase degradation of linolenic acid within chromoplasts. However, other compounds (such as cyclohexanecarboxylic acid esters) may have a microbial origin. Further investigation is necessary to identify the origin of fly attractants in these mosses.

description: Resolving quantum many-body problems represents one of the greatest challenges in physics and physical chemistry, due to the prohibitively large computational resources that would be required by using classical computers. A solution has been foreseen by directly simulating the time evolution through sequences of quantum gates applied to arrays of qubits, i.e. by implementing a digital quantum simulator. Superconducting circuits and resonators are emerging as an extremely-promising platform for quantum computation architectures, but a digital quantum simulator proposal that is straightforwardly scalable, universal, and realizable with state-of-the-art technology is presently lacking. Here we propose a viable scheme to implement a universal quantum simulator with hybrid spin-photon qubits in an array of superconducting resonators, which is intrinsically scalable and allows for local control. As representative examples we consider the transverse-field Ising model, a spin-1 Hamiltonian, and the two-dimensional Hubbard model; for these, we numerically simulate the scheme by including the main sources of decoherence. In addition, we show how to circumvent the potentially harmful effects of inhomogeneous broadening of the spin systems.

CUTICULAR PERMEABILITY AND IONIC REGULATION IN DECAPOD CRUSTACEA
Creators: name: Pequeux, A.
name: Lignon, J.
Publisher: name: Station Biologique de Roscoff (SBR)
Year: 1991

description: The ionic permeabilities of the isolated gill cuticle have been deduced from diffusional transcuticular potential and conductance measurements in several species of decapod crustaceans. It is established that the cuticle permeability depends upon the species considered and its ionoregulation capability, upon the localization of the gill in the gill chamber or even upon the topograhic region in a single gill and upon the nature of the ionic species. In each case the cuticle must always be considered as a diffusion barrier for the main osmotic effectors, Na+ and Cl-. However, the efficiency of this barrier is low in the case of the stenohaline osmoconformers, Homarus, Nephrops, Maia. In hyperregulators such as Astacus, Eriocheir and Carcinus, the efficiency of the cuticular barrier is much higher. The cuticle permeability of the crayfish gill lamina is low for all ionic species but Cl-. In the crayfish gill filaments and in crab gills, permeability to cations is high, but permeability to Cl- is low. In hyperregulators, the cuticle exhibits important differences in its electrical characteristics between the various pairs of gills or even between different topographic regions of the same gill. It shows in addition a functional asymetry which favours ionic influxes. This asymetry is almost inexistant in osmoconforming species. The physiological significance of the cuticle is discussed in relation to the ionoregulation capability of the species and more particularly to the subcuticular spaces described in all gill epithelia of hyperregulator crustacea facing reduced salinity. It is propound that the gill cuticle contributes to reduce ionic leaks in regulators and yet allows for the entry of ions across specific channels at the sites where active uptake takes place.

description: Within the braneworld paradigm the tachyonic scalar field has been used to generate models that attempt to solve some of the open problems that physics faces nowadays, both in cosmology and high energy physics as well. When these field configurations are produced by the interplay of higher dimensional warped gravity with some matter content, braneworld models must prove to be {\it stable} under the whole set of small fluctuations of the gravitational and matter fields background, among other consistency tests. Here we present a complete proof of the stability under scalar perturbations of tachyonic thick braneworlds with an embedded maximally symmetric 4D space-time, revealing its physical consistency. This family of models contains a recently reported tachyonic de Sitter thick braneworld which possesses a series of appealing properties. These features encompass complete regularity, asymptotic flatness (instead of being asymptotically dS or AdS) even when it contains a negative bulk cosmological constant, a relevant 3-brane with dS metric which naturally arises from the full set of field equations of the 5D background (it is not imposed), qualitatively describing the inflationary epochs of our Universe, and a graviton spectrum with a single zero mode bound state that accounts for the 4D graviton localised on the brane and is separated from the continuum of Kaluza-Klein massive graviton excitations by a mass gap. Gauge vector fields with a single massless bound state in its mass spectrum are also localised on this braneworld model a fact that allows us to recover the Coulomb's law of our 4D world. All these properties of the above referred tachyonic braneworld together with the positive stability analysis provided in this work, constitute a firm step towards the construction of realistic cosmological models within the braneworld paradigm.

description: One of the main limitations of utilizing optimal wavefront shaping in imaging and authentication applications is the slow speed of the optimization algorithms currently being used. To address this problem we develop a micro-genetic optimization algorithm ($μ$GA) for optimal wavefront shaping. We test the abilities of the $μ$GA and make comparisons to previous algorithms (iterative and simple-genetic) by using each algorithm to optimize transmission through an opaque medium. From our experiments we find that the $μ$GA is faster than both the iterative and simple-genetic algorithms and that both genetic algorithms are more resistant to noise and sample decoherence than the iterative algorithm.

The use of trophic resources by a generalist eolid nudibranch : Hermissenda crassicornis (Mollusca : Gastropoda)

description: We are presenting the first of a series of studies describing the different trophic strategies of hydroids-eating eolid
 nudibranchs. Hermissenda crassicornis represents the most euriphagous strategy within this trophic guild. We studied the
 natural diet of this eolid based on the analysis of gut content of wild slugs from three different stations along the northern
 California coast, supplemented by laboratory observations. According to our results, H. crassicornis has a broad diet, which
 can vary widely among different environmental situations, but it still exhibits a certain degree of selectivity and some
 preferences. A general trend can be observed in the studied environments: despite its phenotypical specialization to exploit
 cnidarians, H. crassicornis preferred colonial tunicates (mainly Aplidium solidum). Anemones were not frequently
 consumed and probably only the smallest polyps are eaten in the studied environments. Although this species is evolution-
 arily associated with hydroid-eating eolids, hydroids were frequently eaten but always in limited quantity. This pattern of
 consumption led us to suggest two possible explanations that will need further experimentation: (1) hydroids could be
 consumed to obtain a complement of the diet, probably the defensive nematocysts or (2) there is a maximum consumable
 quantity of hydroids conditioned by their toxicity for the nudibranchs.

description: BACKGROUND: Despite the proliferation of health information technology (IT) interventions, descriptions of the unique considerations for conducting randomized trials of health IT interventions intended for patient use are lacking.

PURPOSE: Our purpose is to describe the protocol to evaluate Pocket PATH (Personal Assistant for Tracking Health), a novel health IT intervention, as an exemplar of how to address issues that may be unique to a randomized controlled trial (RCT) to evaluate health IT intended for patient use.

METHODS: An overview of the study protocol is presented. Unique considerations for health IT intervention trials and strategies are described to maintain equipoise, to monitor data safety and intervention fidelity, and to keep pace with changing technology during such trials.

LESSONS LEARNED: The sovereignty granted to technology, the rapid pace of changes in technology, ubiquitous use in health care, and obligation to maintain the safety of research participants challenge researchers to address these issues in ways that maintain the integrity of intervention trials designed to evaluate the impact of health IT interventions intended for patient use.

CONCLUSIONS: Our experience evaluating the efficacy of Pocket PATH may provide practical guidance to investigators about how to comply with established procedures for conducting RCTs and include strategies to address the unique issues associated with the evaluation of health IT for patient use.

description: Η Συναισθηματική Νοημοσύνη θεωρείται πλέον ως μία ξεχωριστή νοημοσύνη και εξίσου σημαντική με την ευφυΐα, για την ανάπτυξη και την ικανοποίηση του ατόμου, βοηθώντας τον κυρίως να διαχειρίζεται και να αναγνωρίζει τα συναισθήματα του, δεξιότητες που τον βοηθάνε στις διαπροσωπικές του σχέσεις. Ένας ηγέτης που επιθυμεί να υπάρχει ευημερία στο περιβάλλον που ηγείται, οφείλει να έχει ανεπτυγμένες τις παραπάνω δεξιότητες, ώστε να προλαμβάνει τις εντάσεις και να χτίζει υγιείς συναδελφικές σχέσεις οι οποίες θα βοηθούν στην εκπλήρωση του οράματος του οργανισμού ή της επιχείρησης. Η ανάπτυξη της Συναισθηματικής Νοημοσύνης των ατόμων σε ηγετικές θέσεις, και κυρίως της ενσυναίσθησης, κρίνεται πιο αναγκαία σε περιβάλλοντα του τομέα υγείας όπου εκεί οι ιατροί και οι νοσηλευτές καλούνται να αντιμετωπίσουν όλες τις δυσκολίες των ασθενών και των συγγενών τους. Ο σκοπός της μελέτης αυτής είναι να εξεταστεί η σχέση της Συναισθηματικής Νοημοσύνης με τις ηγετικές δεξιότητες του ατόμου στις δομές υγείας και κοινωνικής φροντίδας.

Η μελέτη αυτή ανέδειξε ότι η υψηλή Συναισθηματική Νοημοσύνη και παράλληλα οι ανεπτυγμένες συναισθηματικές δεξιότητες, μπορούν να βοηθήσουν τον ηγέτη να επιτύχει τους στόχους του, να δημιουργήσει κλίμα συνεργασίας και εμπιστοσύνης και να αποφασίζει ορθά σε κρίσιμες καταστάσεις.
description: Emotional intelligence is now regarded as a distinct intelligence and just as important as intelligence, to develop and satisfy the individual, helping him mainly manage and recognize his or her feelings, skills that help him in interpersonal relationships. A leader who wishes to have prosperity in the leading environment must have the above skills developed in order to prevent tensions and build healthy collective relationships that will help fulfill the body's vision or business. The 2development of individuals' emotional intelligence in leadership positions, and especially of empathy, is more necessary in health environments where doctors and nurses are called upon to face all the difficulties of patients and their relatives. The purpose of this study is to consider the relationship of emotional intelligence with the leadership skills of the person in health and social care structures. To this end, bibliographic research was carried out and equally Greek and foreign language studies were used. This study has shown that high emotional intelligence and at the same time developed emotional skills can help the leader achieve his goals, create a climate of cooperation and trust, and decide correctly in critical situations.

description: We characterize the expected statistical errors with which the parameters of black-hole binaries can be measured from gravitational-wave (GW) observations of their inspiral, merger and ringdown by a network of second-generation ground-based GW observatories. We simulate a population of black-hole binaries with uniform distribution of component masses in the interval $(3,80)~M_\odot$, distributed uniformly in comoving volume, with isotropic orientations. From signals producing signal-to-noise ratio $\geq 5$ in at least two detectors, we estimate the posterior distributions of the binary parameters using the Bayesian parameter estimation code LALInference. The GW signals will be redshifted due to the cosmological expansion and we measure only the "redshifted" masses. By assuming a cosmology, it is possible to estimate the gravitational masses by inferring the redshift from the measured posterior of the luminosity distance. We find that the measurement of the gravitational masses will be in general dominated by the error in measuring the luminosity distance. In spite of this, the component masses of more than $50\%$ of the population can be measured with accuracy better than $\sim 25\%$ using the Advanced LIGO-Virgo network. Additionally, the mass of the final black hole can be measured with median accuracy $\sim 18\%$. Spin of the final black hole can be measured with median accuracy $\sim 5\% ~(17\%)$ for binaries with non-spinning (aligned-spin) black holes. Additional detectors in Japan and India significantly improve the accuracy of sky localization, and moderately improve the estimation of luminosity distance, and hence, that of all mass parameters. We discuss the implication of these results on the observational evidence of intermediate-mass black holes and the estimation of cosmological parameters using GW observations.

description: Using first-principles calculations, we have investigated the evolution of band-edges in few-layer phosphorene as a function of the number of P layers. Our results predict that monolayer phosphorene is an indirect band gap semiconductor and its valence band edge is extremely sensitive to strain. Its band gap could undergo an indirect-to-direct transition under a lattice expansion as small as 1% along zigzag direction. A semi-empirical interlayer coupling model is proposed, which can well reproduce the evolution of valence band-edges obtained by first-principles calculations. We conclude that the interlayer coupling plays a dominated role in the evolution of the band-edges via decreasing both band gap and carrier effective masses with the increase of phosphorene thickness. A scrutiny of the orbital-decomposed band structure provides a better understanding of the upward shift of valence band maximum surpassing that of conduction band minimum.

description: Increasing evidence suggests that responsiveness is associated with critical or near-critical cortical dynamics, which exhibit scale-free cascades of spatio-temporal activity. These cascades, or ‘avalanches’, have been detected at multiple scales, from in vitro and in vivo microcircuits to voltage imaging and brain-wide functional magnetic resonance imaging (fMRI) recordings. Criticality endows the cortex with certain information-processing capacities postulated as necessary for conscious wakefulness, yet it remains unknown how unresponsiveness impacts on the avalanche-like behaviour of large-scale human haemodynamic activity. We observed a scale-free hierarchy of co-activated connected clusters by applying a point-process transformation to fMRI data recorded during wakefulness and non-rapid eye movement (NREM) sleep. Maximum-likelihood estimates revealed a significant effect of sleep stage on the scaling parameters of the cluster size power-law distributions. Post hoc statistical tests showed that differences were maximal between wakefulness and N2 sleep. These results were robust against spatial coarse graining, fitting alternative statistical models and different point process thresholds, and disappeared upon phase-shuffling the fMRI time series. Evoked neural bistabilities preventing arousals during N2 sleep do not suffice to explain these differences, which point towards changes in the intrinsic dynamics of the brain that could be necessary to consolidate a state of deep unresponsiveness.

description: The subject of the present dissertation is the icon "the Virgin Mary with Saints" (Inventory Number 3622), which belongs to the collection of the National Museum of Medieval Art in Korça. This icon is of particular interest due to the existence of two additional layers of painting, that is to say, it is an overpainting icon. To identify the components of the materials, but also the mechanisms of deterioration that has affected the icon, specific physical-chemical analyzes were applied, such as Radiography, Stereomicroscopy, Optical Microscopy, Scanning Electron Microscopy (SEM-EDS) and Infrared Fluorescence (FTIR). Finally, based on the information gathered from the application of the aforementioned techniques, a proposal for the restoration of this icon was drawn up.

description: Το φυσικό σχολικό περιβάλλον επιδρά σημαντικά στη μάθηση και την απόδοση κατά την εκπαιδευτική διαδικασία, ενώ παράλληλα έχει αποδειχθεί ότι η ποιότητά του επηρεάζει και την υγεία των μαθητών. Έρευνες που μελετούν την επίδραση παραγόντων του φυσικού περιβάλλοντος στους μαθητές έχουν πραγματοποιηθεί σε όλες τις βαθμίδες της εκπαιδευτικής διαδικασίας. Οι σημαντικότεροι από αυτούς είναι η ποιότητα των κτιριακών σχολικών εγκαταστάσεων, ο φωτισμός, η ποιότητα του αέρα, η θερμοκρασία, η ακουστική – θόρυβος και τα επιμέρους χαρακτηριστικά της σχολικής αίθουσας. Σκοπός της παρούσας εργασίας ήταν η διερεύνηση των παραγόντων του φυσικού σχολικού περιβάλλοντος που επηρεάζουν τους μαθητές λυκείου. Πραγματοποιήθηκε ανασκόπηση της διεθνούς βιβλιογραφίας και συλλέχθηκαν έρευνες που ως αντικείμενο είχαν την επίδραση τους σχολικού φυσικού περιβάλλοντος σε μαθητές λυκείων. Καταγράφηκαν οι παράγοντες που επηρεάζουν την μάθηση, την απόδοση και την υγεία των μαθητών και αναφέρθηκαν τα αποτελέσματα των ερευνών αυτών. Παρά το γεγονός ότι η πλειοψηφία των ερευνών που έχουν πραγματοποιηθεί σε μικρότερες ηλικίες (μαθητές δημοτικού), επιβεβαιώνεται πως παράγοντες του φυσικού σχολικού περιβάλλοντος επηρεάζουν σημαντικά και μαθητές μεγαλύτερης ηλικίας. Κρίνεται απαραίτητο η εκπαιδευτική διαδικασία να υλοποιείται σε ένα ποιοτικό σχολικό περιβάλλον το οποίο προάγει με αυτό τον τρόπο την μάθηση και την επικοινωνία των μαθητών, χωρίς επιπτώσεις στην υγεία τους.
description: Indoor school environment effects learning and academic achievement during educational process, and its quality has proven to play a significant role in students health. Research in the field has included all educational levels. The most important factors of indoor school environment found to effect students are the quality of the facilities, lighting, air quality and temperature, acoustics – noise and classroom’s facilities. The aim of the present study was to research the factors of indoor school environment that effect secondary high school students. Research of literature was performed aiming to explore the effect indoor school environment on secondary high school students. Factors that affect learning, academic achievement and health have been recorded and results have been displayed. Although most of research in the field concerns elementary students research has proven that many factors of indoor physical environment significantly effect older students. It is crucial for an effective educational process to be held in quality environment that promotes learning and communication as well as the health of students.

description: Increasing evidence suggests that responsiveness is associated with critical or near-critical cortical dynamics, which exhibit scale-free cascades of spatio-temporal activity. These cascades, or ‘avalanches’, have been detected at multiple scales, from in vitro and in vivo microcircuits to voltage imaging and brain-wide functional magnetic resonance imaging (fMRI) recordings. Criticality endows the cortex with certain information processing capacities postulated as necessary for conscious wakefulness, yet it remains unknown how unresponsiveness impacts on the avalanche-like behaviour of large-scale human hemodynamic activity. We observed a scale-free hierarchy of co-activated connected clusters by applying a point-process transformation to fMRI data recorded during wakefulness and non-rapid eye movement (NREM) sleep. Maximum-likelihood estimates revealed a significant effect of sleep stage on the scaling parameters of the cluster size power-law distributions. Post hoc statistical tests showed that differences were maximal between wakefulness and N2 sleep. These results were robust against spatial coarse-graining, fitting alternative statistical models, and different point-process thresholds, and disappeared upon phase-shuffling the fMRI time series. Evoked neural bistabilities preventing arousals during N2 sleep do not suffice to explain these differences, which point towards changes in the intrinsic dynamics of the brain that could be necessary to consolidate a state of deep unresponsiveness.

The ciliate Orchitophrya stellarum viewed as a facultative parasite of asteriid sea stars

description: Orchitophrya stellarum Cépède, 1907 is a ciliate that consumes sperm in the testes of male asteriid sea stars in
 the Pacific and North Atlantic oceans. Previous studies have reported its presence in smears and sections of testes, and we
 have also observed it in the spawn. This organism is easily cultured in seawater containing bacteria nourished by yeast
 extract or tissues from various marine invertebrates and the domestic chicken. During adaptation to culture conditions, the
 ciliates become smaller, the number of kineties is reduced, and the buccal cavity is shifted farther away from the anterior
 end. These changes are reversed if the ciliates are fed sperm of asteriid sea stars. Orchitophrya stellarum is therefore consi-
 dered to be a facultative parasite that can live indefinitely in situations where it can feed on bacteria and tissue detritus. It
 probably enters the testes of reproductively mature male sea stars by way of the gonopores.

description: Attitudinal data are commonly used to measure values, which in turn represent moral doctrines that are resistant to change and are the foundation for societal norms. This article examines changes in the attitudinal climate in Japan. Three national surveys (1994, 2000, and 2009) are used to examine a range of attitudes that measure a) the centrality of marriage and childbearing, b) nontraditional family behaviors, and c) gender roles in the work and family spheres. There is strong evidence of movement toward less-traditional attitudes during 1994–2000, followed by limited change in the 2000s. Period factors were paramount in the 1990s. Across the board, women hold less-traditional attitudes than men, and this difference has increased over time. Both engaging in nontraditional family behaviors (being married but remaining childless) and knowing someone who has engaged in nontraditional family behaviors (cohabitation) causally lead to holding nontraditional attitudes, suggesting mechanisms whereby changes in individual behavior can lead to changes in societal values.

description: OBJECTIVE: This study examined barriers to mental health service use and preferences for addressing emotional concerns among lung cancer patients (N=165) at two medical centers in the Midwestern United States.

METHODS: Lung cancer patients completed an assessment of anxiety and depressive symptoms, mental health service use, barriers to using these services, and preferences for addressing emotional concerns.

RESULTS: Only 45% of distressed patients received mental health care since their lung cancer diagnosis. The most prevalent patient-reported barriers to mental health service use among non-users of these services (n=110) included the desire to independently manage emotional concerns (58%) and inadequate knowledge of services (19%). In addition, 57% of distressed patients who did not access mental health services did not perceive the need for help. Seventy-five percent of respondents (123/164) preferred to talk to a primary care physician if they were to have an emotional concern. Preferences for counseling, psychiatric medication, peer support, spiritual care, or independently managing emotional concerns also were endorsed by many patients (range=40-50%). Older age was associated with a lower likelihood of preferring to see a counselor.

CONCLUSIONS: Findings suggest that many distressed lung cancer patients underuse mental health services and do not perceive the need for such services. Efforts to increase appropriate use of services should address patients' desire for autonomy and lack of awareness of services.
Temperature-averaged and total free-free Gaunt factors for $κ$ and Maxwellian distributions of electrons

description: Aims. Optically thin plasmas may deviate from thermal equilibrium and thus, electrons (and ions) are no longer described by the Maxwellian distribution. Instead they can be described by $κ$-distributions. The free-free spectrum and radiative losses depend on the temperature-averaged (over the electrons distribution) and total Gaunt factors, respectively. Thus, there is a need to calculate and make available these factors to be used by any software that deals with plasma emission. Methods. We recalculated the free-free Gaunt factor for a wide range of energies and frequencies using hypergeometric functions of complex arguments and the Clenshaw recurrence formula technique combined with approximations whenever the difference between the initial and final electron energies is smaller than $10^{-10}$ in units of $z^2Ry$. We used double and quadruple precisions. The temperature- averaged and total Gaunt factors calculations make use of the Gauss-Laguerre integration with 128 nodes. Results. The temperature-averaged and total Gaunt factors depend on the $κ$ parameter, which shows increasing deviations (with respect to the results obtained with the use of the Maxwellian distribution) with decreasing $κ$. Tables of these Gaunt factors are provided.
