description: This thesis investigates deviant morphology in Indonesian for the implementation of a deep grammar. In particular we focus on the implementation of the verbal suffix -kan. This suffix has been described as having many functions, which alter the kinds of arguments and the number of arguments the verb takes (Dardjowidjojo 1971; Chung 1976; Arka 1993; Vamarasi 1999; Kroeger 2007; Son and Cole 2008). Deep grammars or precision grammars (Butt et al. 1999a; Butt et al. 2003; Bender et al. 2011) have been shown to be useful for natural language processing (NLP) tasks, such as machine translation and generation (Oepen et al. 2004; Cahill and Riester 2009; Graham 2011), and information extraction (MacKinlay et al. 2012), demonstrating the need for linguistically rich information to aid NLP tasks. Although these linguistically-motivated grammars are invaluable resources to the NLP community, the biggest drawback is the time required for the manual creation and curation of the lexicon. Our work aims to expedite this process by applying methods to assign syntactic information to kan-affixed verbs automatically. The method we employ exploits the hypothesis that semantic similarity is tightly connected with syntactic behaviour (Levin 1993). Our endeavour in automatically acquiring verbal information for an Indonesian deep grammar poses a number of lingustic challenges. First of all Indonesian verbs exhibit voice marking that is characteristic of the subgrouping of its language family. In order to be able to characterise verbal behaviour in Indonesian, we first need to devise a detailed analysis of voice for implementation. Another challenge we face is the claim that all open class words in Indonesian, at least as it is spoken in some varieties (Gil 1994; Gil 2010), cannot linguistically be analysed as being distinct from each other. That is, there is no distiction between nouns, verbs or adjectives in Indonesian, and all word from the open class categories should be analysed uniformly. This poses difficulties in implementing a grammar in a linguistically motivated way, as well discovering syntactic behaviour of verbs, if verbs cannot be distinguished from nouns. As part of our investigation we conduct experiments to verify the need to employ word class categories, and we find that indeed these are linguistically motivated labels in Indonesian. Through our investigation into deviant morphological behaviour, we gain a better characterisation of the morphosyntactic effects of -kan, and we discover that, although Indonesian has been labelled as a language with no open word class distinctions, word classes can be established as being linguistically-motivated.

description: Let $Ω$ be a Carleson-Denjoy domain and $G$ be its covering group. Let $μ$ be a Beltrami coefficient on the unit disk which is compatible with the group $G$. In this paper we show that if $\frac{|μ|^{2}}{1-|z|^{2}}dxdy$ satisfies the Carleson condition on the infinite boundary of the Dirichlet fundamental domain of $G$, then $\frac{|μ|^{2}}{1-|z|^{2}}dxdy$ is a Carleson measure on the unit disk. We also show that the above property does not hold for Denjoy domain.

description: Swarm of drones are increasingly being asked to carry out missions that can't be completed by one drone. Particularly, in delivery, issues arise due to the swarm's limited flight endurance. Hence, we propose a novel formation-guided framework for selecting Swarm-based Drone-as-a-Service (SDaaS) for delivery. A detailed study is carried out to highlight the effect of swarm formations on energy consumption. Two SDaaS selection approaches, i.e. Fixed and Adaptive, are designed considering the different formation decisions a swarm can take. The proposed framework considers extrinsic constraints including wind speed and direction. We propose SDaaS selection algorithms for each approach. Experimental results prove the efficiency of the proposed algorithms.

description: I describe very briefly the new libraries of empirical spectra of stars covering wide ranges of values of the atmospheric parameters Teff, log g, [Fe/H], as well as spectral type, that have become available in the recent past, among them the HNGSL, MILES, UVES-POP, and Indo-US libraries. I show the results of using the HNGSL to build population synthesis models. These libraries are complementary in spectral resolution and wavelength coverage, and will prove extremely useful to describe spectral features expected in galaxy spectra from the NUV to the NIR.

description: In this paper, we report the results obtained from the acceleration of multi-binary64-type multiple precision matrix multiplication with AVX2. We target double-double (DD), triple-double (TD), and quad-double (QD) precision arithmetic designed by certain types of error-free transformation (EFT) arithmetic. Furthermore, we implement SIMDized EFT functions, which simultaneously compute with four binary64 numbers on x86_64 computing environment, and by using help of them, we also develop SIMDized DD, TD, and QD additions and multiplications. In addition, AVX2 load/store functions were adopted to efficiently speed up reading and storing matrix elements from/to memory. Owing to these combined techniques, our implemented multiple precision matrix multiplications have been accelerated more than three times compared with non-accelerated ones. Our accelerated matrix multiplication modifies the performance of parallelization with OpenMP.

description: We present PDFFlow, a new software for fast evaluation of parton distribution functions (PDFs) designed for platforms with hardware accelerators. PDFs are essential for the calculation of particle physics observables through Monte Carlo simulation techniques. The evaluation of a generic set of PDFs for quarks and gluon at a given momentum fraction and energy scale requires the implementation of interpolation algorithms as introduced for the first time by the LHAPDF project. PDFFlow extends and implements these interpolation algorithms using Google's TensorFlow library providing the capabilities to perform PDF evaluations taking fully advantage of multi-threading CPU and GPU setups. We benchmark the performance of this library on multiple scenarios relevant for the particle physics community.

description: Xylotrechus arvicola is an invasive insect on Vitis vinifera in the main wine-producing regions of the Iberian Peninsula. X. arvicola larvae bore into the grapevine wood and make galleries, which cause structural damages to the plant. The aim of this study was to investigate how grapevine wood infested by larvae affects the mechanical properties of the plant in comparation with those of uninfested wood. Samples of grapevine wood uninfested and infested by larvae were collected from vineyards. Compression and flexural strengths as well as simulated structures of grapevine wood in field, in relation to harvest weight by variety, were used to quantify the wood mechanical properties. Infested wood endured a lower strength and normal tension, and exhibited a reduction in the structural capacities in the simulation of harvest weight of 'Cabernet-Sauvignon' variety (up to 62.0 %). 'Tempranillo' (despite its high mechanical slenderness values) and 'Cabernet-Sauvignon', were the varieties that showed a higher resistance on trunks and branches, respectively. A lower bending moment was observed on the infested branches of all varieties. Changes in the mechanical properties of infested wood suggest a decrease in mechanical resistance of wood attacked by larvae that could contribute to the rupture of the infested grapevine over time. Grapevine wood attacked by X. arvicola larvae could be more sensitive to mechanical external factors in vineyards such as strong winds, harvest weight and vibration exerted by harvesting machines.

description: Although the use of under-trellis plants as weed control (living mulch) in vineyards has been gaining popularity, its effects on soil quality and especially soil biology have not been well studied. Due to functional trait differences, plants may differ in how they compete with vines, and may also change abiotic and biotic soil properties. A living mulch trial was established in the semi-arid Okanagan valley of British Columbia comparing vine growth as well as soil abiotic and biotic outcomes for four living mulch treatments: buffalo grass (Bouteloua dactyloides), Chewing's fescue (Festuca rubra ssp. commutata), birdsfoot trefoil (Lotus corniculatus), and shepherd's purse (Capsella bursa-pastoris) with two industry standards: herbicide and cultivation. After two seasons, strong vine growth responses were seen that depended on living mulch identity, e.g., reduction in leaf N status with grasses, reduction in leaf water potential with the legume, birdsfoot trefoil. These effects were related to plant-induced changes to soil C:N ratio and soil moisture. Although treatments did not change abundance of the measured fungal guilds in bulk soil, abundance of arbuscular mycorrhizal fungi in vine roots was lowest with birdsfoot trefoil as living mulch. This study may help growers to select living mulch species appropriate for the soil conditions and resource availability of their site.

description: The change of wine grape harvest from wet season (summer) to dry season (winter) by changing the pruning management has improved quality of wines produced in the Brazilian Southeast. However, the vines need to be spur pruned twice a year, i.e. with a 1st pruning in August (winter pruning) for a vegetative cycle during the hot and wet summer, and a 2nd pruning in January (summer pruning) for a productive cycle during the cold and dry season. This double pruning strategy is made necessary by the fact that latent buds developed during the dry season cycle are not fruitful to support a productive cycle in the following year. This histological study, performed in the South of Minas Gerais State (Brazil), showed that annual single pruning done in the wet season (in January) displayed a high rate of necrosis on primary and secondary buds (bud necrosis – BN). In April, 99 days after summer pruning (DASP), the rates of BN were 40 % and 50 % at basal and apical node positions, respectively, reaching 80 % of BN in December (322 DASP). As a consequence of BN, bud potential fertility was drastically reduced from 0.5 inflorescence primordial (IP) per bud (in July) to 0.06 (in December) and bud burst in the next cycle from secondary and tertiary bud axes. Vines managed by double pruning system (submitted to summer and winter pruning) displayed a much higher fruitfulness potential, i.e. 1.46 IP per bud in December (112 days after winter pruning) and limited BN occurrence (20 %). On single pruned vines, we also observed a significant decrease of starch content in canes, trunks and roots. Internal bud anatomy showed that a random cell breakdown started 70 days DASP. At 211 DASP, all buds showed a large starch granule concentration, raphides and crystals of calcium oxalate inside idioblasts of leaf primordia and also in cortical parenchyma of the vegetative axis. The bud starch content was increased and a positive correlation between necrosis and starch accumulation was observed. The impact of carbohydrate availability on bud necrosis development was discussed. This study showed that the necrosis development towards secondary and tertiary axis of the dry season buds is the main reason of unfruitfulness in the vineyards managed by single pruning in the wet season, making the double pruning compulsory.

An Increase in Small-planet Occurrence with Metallicity for Late-type Dwarf Stars in the Kepler Field and Its Implications for Planet Formation

description: While it is well established that giant-planet occurrence rises rapidly with host star metallicity, it is not yet clear if small-planet occurrence around late-type dwarf stars depends on host star metallicity. Using the Kepler Data Release 25 planet candidate list and its completeness data products, we explore planet occurrence as a function of metallicity in the Kepler field's late-type dwarf stellar population. We find that planet occurrence increases with metallicity for all planet radii $R_{\mathrm{p}}$ down to at least $R_{\mathrm{p}}\approx2~R_{\oplus}$ and that in the range $2~R_{\oplus}\lesssim R_{\mathrm{p}}\lesssim 5~R_{\oplus}$ planet occurrence scales linearly with metallicity $Z$. Extrapolating our results, we predict that short-period planets with $R_{\mathrm{p}}\lesssim 2~R_{\oplus}$ should be rare around early M dwarf stars with $\mathrm{[M/H]}\lesssim-0.5$ or late M dwarf stars with $\mathrm{[M/H]}\lesssim+0.0$. This dependence of planet occurrence on metallicity observed in the Kepler field emphasizes the need to control for metallicity in estimates of planet occurrence for late-type dwarf stars like those targeted by Kepler's K2 extension and the Transiting Exoplanet Survey Satellite (TESS). We confirm the theoretical expectation that the small planet occurrence--host star metallicity relation is stronger for low-mass stars than for solar-type stars. We establish that the expected solid mass in planets around late-type dwarfs in the Kepler field is comparable to the total amount of planet-making solids in their protoplanetary disks. We argue that this high efficiency of planet formation favors planetesimal accretion over pebble accretion as the origin of the small planets observed by Kepler around late-type dwarf stars.

description: As global warming concerns continue to rise, research has shifted towards developing more climate-friendly refrigerants for air-conditioning and refrigeration compressors, with HFO-1234yf being a prominent candidate. In line with the need for lightweight engineering in electric vehicles, advanced composite coatings are necessary to improve the surface properties of parts and system components made from light metals such as magnesium and aluminum, which typically have poor tribological performance. This study investigates the tribological performance of advanced polymeric coatings (ATSP-, PTFE-, and PEEK-based) on lightweight aluminum alloy substrates in the presence of HFO-1234yf refrigerant and polyalkylene glycol (PAG) lubricant under starved lubrication conditions. Using a high-pressure tribometer, scuffing pressure, friction, and wear experiments were conducted, with all three coatings exhibiting excellent tribological performance compared to the bare substrate. Notably, PEEK and ATSP coatings demonstrated superior performance with high load-to-failure, low coefficient of friction, and negligible wear. Results also showed ATSP to have superior durability against a broad range of stress levels, while PEEK coating partially wears out at higher stress levels. These findings provide valuable insights for developing robust coatings on lightweight materials for high-stress applications.

description: The two tone intermodulation distortion arising in MgB2 thin films synthesized by hybrid physical-chemical vapour deposition is studied in order to probe the influence of the two bands on the nonlinear response of this superconductor. The measurements are carried out by using a dielectrically loaded copper cavity operating at 7 GHz. Microwave data on samples having critical temperatures above 41 K, very low resistivity values, and residual resistivity ratio larger than 10, are shown. The dependence of the nonlinear surface losses and of the third order intermodulation products on the power feeding the cavity and on the temperature is analyzed. At low power, the signal arising from distortion versus temperature shows the intrinsic s-wave behavior expected for this compound. Data are compared with measurements performed on Nb and YBCO thin films using the same technique.

Fast Area-Weighted Peeling of Convex Hulls for Outlier Detection

description: We present a novel 2D convex hull peeling algorithm for outlier detection, which repeatedly removes the point on the hull that decreases the hull's area the most. To find k outliers among n points, one simply peels k points. The algorithm is an efficient heuristic for exact methods, which find the k points whose removal together results in the smallest convex hull. Our algorithm runs in O(nlogn) time using O(n) space for any choice of k. This is a significant speedup compared to the fastest exact algorithms, which run in O(n^2logn + (n - k)^3) time using O(n\logn + (n-k)^3) space by Eppstein et al., and O(nlogn + 4k_C_2k (3k)^k n) time by Atanassov et al. Existing heuristic peeling approaches are not area-based. Instead, an approach by Harsh et al. repeatedly removes the point furthest from the mean using various distance metrics and runs in O(nlogn + kn) time. Other approaches greedily peel one convex layer at a time, which is efficient when using an O(nlogn) time algorithm by Chazelle to compute the convex layers. However, in many cases this fails to recover outliers. For most values of n and k, our approach is the fastest and first practical choice for finding outliers based on minimizing the area of the convex hull. Our algorithm also generalizes to other objectives such as perimeter.

The Perception of Skills for Maximizing Patient Comfort During Non-Invasive Ventilation Among Respiratory Therapists at KFSH&RC
Creators: name: Albaqawi, Ahmed
Publisher: name: Georgia State University
Year: 2023

description:
Background: Noninvasive ventilation (NIV) is a modality that supports patient breathing through different types of face ?interfaces, such as a full-face mask and nasal mask. Noninvasive Ventilation modalities have proven to improve morbidity and mortality rates for patients suffering from respiratory failure in the hospital setting and Outpatient. It also helped prevent escalating the treatment to more advanced methods such as invasive ventilation. However, several elements are required for optimizing the therapy, including Health care providers' training in operating the different brands of NIV, equipment availability, cost, and appropriate adjustment to the settings according to patient response. Purpose: This study aims to assess the level of perception of maximizing patient comfort during non-invasive ventilation devices among respiratory therapists at KFSH&RC by utilizing specific features of NIV. For instance, ramp, Flex, humidification, and auto-adjusting pressure. In addition, how RTs perceive mask selection and other contributing factors that contribute to maximizing patients' comfort. Methods: The study used an online, cross-sectional survey with 20 questions were sent to Respiratory therapists at KFSH&RC. In this survey, data collected from targeted population regarding their perceptions of skills for maximizing patient comfort during non-invasive ventilation will be analyzed using the Statistical Package for the Social Sciences (SPSS). Result: The findings indicated that respiratory therapists at KFSH&RC generally hold a positive view about utilizing various aspects of NIV, such as auto-adjusting pressure, noise reduction, humidification, and specific NIV settings, to maximize patient comfort. They also recognized the importance of effective communication, patient encouragement, and addressing patient comfort before and after initiating NIV therapy. The study found that demographic factors like gender, country of graduation, years of experience, and age did not significantly impact the therapists' attitudes, except for therapists working in respiratory care community services (RCCS), who placed greater emphasis on maximizing patient comfort during NIV (P=.019). Conclusion: This research conducted at King Faisal Specialist Hospital & Research Centre (KFSH&RC) concluded that respiratory therapists demonstrated positive perception about utilizing different elements of NIV to maximize patient comfort during therapy. Majority of therapists believed that features such as auto-adjusting pressure, noise reduction, humidification, and the utilization of certain NIV settings such as the FLEX and RAMP have significance for enhancing patient comfort.

description: Anomalous Cepheids (ACs) are metal-deficient, core-helium-burning pulsating stars with masses in the range 1.2-2.2 M_S. Until recently, all known ACs were pure single-mode pulsators. The first candidate for an AC pulsating in more than one radial mode - OGLE-GAL-ACEP-091 - was recently identified in the Milky Way based on the photometric database of the Optical Gravitational Lensing Experiment (OGLE) survey. We analyze this object showing that it is actually a triple-mode pulsator. Its position in the Petersen diagram, the light-curve morphology quantified by Fourier coefficients, and absolute magnitudes derived from the Gaia parallax are consistent with the assumption that OGLE-GAL-ACEP-091 is an AC. Our grid of linear pulsation models indicates that OGLE-GAL-ACEP-091 is a 1.8 M_S star with a metallicity of about [Fe/H] = -0.5 dex.

description: The notion of the Fibonacci cobweb poset from [1] has been naturally extended to any admissible sequence $F$ in [2] where it was also recognized that the celebrated prefab notion of Bender and Goldman [3] - (see also [4,5]) - admits such an extension so as to encompass the new type combinatorial objects from [2] as leading examples. Recently the present author had introduced also [6] two natural partial orders in there: one $\leq$ in grading-natural subsets of cobweb`s prefabs sets [2] and in the second proposal one endows the set sums of the so called "prefabiants" with such another partial order that one arrives at Bell-like numbers including Fibonacci triad sequences introduced by the present author in [7]. Here we quote the basic observations concerning the new type Stirling like numbers as they appear in [6]. For more on notation, Stirling like numbers of the first kind and for proofs - see [6].

Year: 2023

description:
Background: In response to the COVID-19 pandemic, electronic learning (E-learning) has emerged as the primary method for delivering educational materials, particularly within the scope of Saudi Arabian (SA) Respiratory Therapy (RT) education. PURPOSE: To evaluate the perception of E-learning among RT students in the Kingdom of Saudi Arabia (KSA) by comparing face-to-face learning to E-learning during the COVID-19 pandemic. METHODS: A cross-sectional survey to investigate the perception of E-learning was conducted and distributed using a convenience sample of RT students through an online platform (Google Forms) between September and November 2023. RESULTS: Overall, 221 RT students, with females accounting for 119 (53.8%), replied to the online survey. The study revealed several advantages of E-learning, including the ability to study at home (67.9%), access to online materials (64.7%), and learning at own pace (62.4%). The main disadvantages as indicated by most respondents were the lack of interactions with patients (70.1%), technical problems (56.6%), and reduced interaction with teachers (50.7%). No significant difference in the perceptions of knowledge enhancement between face-to-face and E-learning methods (P = .32). However, E-learning was considered a lower effective method than face-to-face learning for both clinical skill development (P < .001), and social competencies (P < .001). Additionally, respondents reported that they were less actively engaged during E-learning classes compared to face-to-face classes (P < .001). Nonetheless, a significant percentage of respondents (71.9%) claimed that E-learning was an enjoyable experience. CONCLUSION: This research emphasizes the potency of E-learning in terms of increasing knowledge as a valuable tool for educating Saudi RT students. Nevertheless, it highlights the need for a meticulously planned strategy and a proactive implementation approach to effectively implement clinical and social skills E-learning into the educational framework of RT students.

Our context is estimating a bounded function $ϕ$ of a parameter when the loss is quadratic. If the posterior mean of $ϕ$ is admissible for all bounded $ϕ$, the posterior is strongly admissible. We give sufficient conditions for strong admissibility. These conditions involve the recurrence of a Markov chain associated with the estimation problem. We develop general sufficient conditions for recurrence of general state space Markov chains that are also of independent interest. Our main example concerns the $p$-dimensional multivariate normal distribution with mean vector $θ$ when the prior distribution has the form $g(\|θ\|^2) dθ$ on the parameter space $\mathbb{R}^p$. Conditions on $g$ for strong admissibility of the posterior are provided.

description: The theories of stochastic quantum mechanics and stochastic electrodynamics bring to light important aspects of the quantum dynamics that are concealed in the standard formalism. Here we take further previous work regarding the connection between the two theories, to exhibit the role of stochasticity and diffusion in the process leading from the originally classical+zpf regime to the quantum regime. Quantumlike phenomena present in other instances in which a mechanical system is subject to an appropriate oscillating background that introduces stochasticity, may point to a more general appearance of quantization under such circumstances.

description:
Background: Anxiety and depression are prevalent concerns among psychologists, psychiatric professionals, and behavioral scientists across the world. Anxiety is defined as worry-filled thoughts and a pervasive sense of impending doom. It is a broad concern about what will or might occur in the future. Depression is a debilitating disorder, leading to higher death rates and a significant decline in the quality of life. It is characterized by persistent feelings of sadness, emptiness, and lack of happiness. Therefore, anxiety and depression could have a detrimental effect on the well-being and productivity of respiratory therapists. Purpose: The purpose of this study is to investigate the prevalence and severity of anxiety and depression among respiratory therapists employed by public and private hospitals in the western region of Saudi Arabia. Methods: A cross-sectional study was conducted between September 5 and October 7, 2023. The Hospital Anxiety and Depression Scale (HADS) was distributed electronically to respiratory therapists' email addresses through direct collaboration with RT department heads. Data were collected from RT professionals in both public and private hospitals by using a non-probability convenience sampling technique. The data analysis and statistical description provided by the participants were displayed as means, standard deviations, frequencies, and percentages. A one-way ANOVA test was used to determine the significant differences in HADS scores among categorical groups. Results: A total of 307 responses were received from RTs working in the western region of Saudi Arabia. The majority of them were from public hospitals (74.3%) and (25.7%) from private hospitals. The study findings showed that the prevalence of anxiety and depression among RT professionals in the western of SA were found to be 38.8% and 37.5%, respectively. In addition, HADS scores were significantly higher among RT professionals who were female, current smokers, divorced, or widowed. However, HADS showed that anxiety was significantly higher among RT professionals with clinical experience between 1-4 years as well. Conclusion: Anxiety and depression were common psychological disorders among respiratory therapists in the western region of Saudi Arabia. Higher odds of anxiety and depression were significantly found among females, staff with clinical experience between 1 and 4 years, smokers, and divorced/widowed staff. Further studies are required to investigate the prevalence of depression and anxiety among RTs in all regions of Saudi Arabia.

description: If $A_q(β, α, k)$ is the scattering amplitude, corresponding to a potential $q\in L^2(D)$, where $D\subset\R^3$ is a bounded domain, and $e^{ikα\cdot x}$ is the incident plane wave, then we call the radiation pattern the function $A(β):=A_q(β, α, k)$, where the unit vector $α$, the incident direction, is fixed, and $k>0$, the wavenumber, is fixed. It is shown that any function $f(β)\in L^2(S^2)$, where $S^2$ is the unit sphere in $\R^3$, can be approximated with any desired accuracy by a radiation pattern: $||f(β)-A(β)||_{L^2(S^2)}0$ is an arbitrary small fixed number. The potential $q$, corresponding to $A(β)$, depends on $f$ and $ε$. There is a one-to-one correspondence between the above potential and the density of the number of small acoustically soft particles $D_m\subset D$, $1\leq m\leq M$, distributed in an a priori given bounded domain $D\subset\R^3$. The geometrical shape of a small particle $D_m$ is arbitrary, the boundary $S_m$ of $D_m$ is Lipschitz uniformly with respect to $m$. The wave number $k$ and the direction $α$ of the incident upon $D$ plane wave are fixed. It is shown that a suitable distribution of the above particles in $D$ can produce the scattering amplitude $A(α',α)$, $α',α\in S^2$, at a fixed $k>0$, arbitrarily close in the norm of $L^2(S^2\times S^2)$ to an arbitrary given scattering amplitude $f(α',α)$, corresponding to a real-valued potential $q\in L^2(D)$, i.e., corresponding to an arbitrary given refraction coefficient in $D$.
The clinical relevance of perioperative Factor XIII levels in open biliary surgery for obstructive jaundice

description: Background and Goal of Study: Factor XIII (F XIII) consists of potentially active A2 and inhibitory
B2 subunits, which crosslinks subunits of the fibrin clot to form insoluble fibrin. Since B2 is synthesized by hepatocytes, their failure may confer a bleeding diathesis when F XIII plasma activity is decreased ≤ 50%. Little is known about the pattern and significance of the F XIII changes after surgery for obstructive jaundice (OJ), which is the aim of our study.

Conclusion(s): In patients undergoing open biliary surgery for OJ (accompanied or not by biliary inflammation), the changes in F XIII are not isolated, but go with the changes in other haemostasis parameters (such as PT, aPTT, AT III, antiplasmin). The latter fact is of clinical relevance as it is associated with increase perioperative haemorrhage requiring correction with FFP (and the like).
Effectiveness of true acupuncture as an adjunct to stanard care or electro-physiotherapy in ostheoarthritis of the knee

description: Aim of investigation: Recently there has been considerable academic debate about the effectiveness of true acupuncture as an adjunctive treatment in osteoarthritis (OA) of the knee. The results from acupuncture studies are inconclusive. The aim of the present research is to find out prospectively the extent of pain relief and improved function in patients (pts) with knee OA after the implementation of 2 weeks standard care treatment followed by 2 weeks classical true acupuncture treatment compared with 2 weeks physiotherapy treatment followed by 2 weeks classical true acupuncture as well.

Conclusions: These results demonstrate the potential of an integrative approach including the complementary treatment of knee OA with a combination of electro-physiotherapy and true acupuncture in a consecutive and more intense manner (according to our local practice). Further research in the conventional and alternative management of knee OA should focus not only on the quality of pts life after treatments, but on the quality of available pharmacological and non-pharmacological treatment options as well.
AGN self-regulation in cooling flow clusters

description: We use three-dimensional high-resolution adaptive-mesh-refinement simulations to investigate if mechanical feedback from active galactic nucleus jets can halt a massive cooling flow in a galaxy cluster and give rise to a self-regulated accretion cycle. We start with a 3 x 10^9MSun black hole at the centre of a spherical halo with the mass of the Virgo cluster. Initially, all the baryons are in a hot intracluster medium in hydrostatic equilibrium within the dark matter's gravitational potential. The black hole accretes the surrounding gas at the Bondi rate and a fraction of the accretion power is returned into the intracluster medium mechanically through the production of jets. The accretion, initially slow (~0.0002MSun/yr), becomes catastrophic, as the gas cools and condenses in the dark matter's potential. Therefore, it cannot prevent the cooling catastrophe at the centre of the cluster. However, after this rapid phase, where the accretion rate reaches a peak of ~0.2MSun/yr, the cavities inflated by the jets become highly turbulent. The turbulent mixing of the shock-heated gas with the rest of the intracluster medium puts a quick end to this short-lived rapid-growth phase. After dropping by almost two orders of magnitudes, the black hole accretion rate stabilises at ~0.006MSun/yr, without significant variations for several billions of years, indicating that a self-regulated steady-state has been reached. This accretion rate corresponds to a negligible increase of the black hole mass over the age of the Universe, but is sufficient to create a quasi-equilibrium state in the cluster core.

description:
Background: Insomnia is a common sleep disorder characterized by difficulties falling asleep, staying asleep, or waking up early in the morning, along with significant distress and impairments of daytime functioning. It is a prevalent sleep complaint among health science students, due to an overburdened academic load, protracted intensive study periods, and stressful lifestyles to maintain an outstanding grade point average (GPA). Therefore, insomnia can adversely affect students' health and academic performance. Purpose: This study aimed to assess the prevalence of insomnia and its impact on academic performance among respiratory therapy students in Saudi Arabia (SA) and the United States of America (USA). Methods: A cross-sectional study was conducted between June 9 and September 12, 2023. Insomnia Severity Index (ISI) was distributed electronically to students' email addresses through direct coordination with RT department directors. Data were collected from RT students in both countries by using a non-probability convenience sampling technique. Descriptive statistics of the participants were presented in frequencies, percentages, means, and standard deviations. A one-way ANOVA test was used to measure the significant differences of ISI scores among categorical groups. Results: A total of 403 responses were received from both countries. The majority of them were from Saudi Arabia (79.9%) and (20.1%) from the United States. The study findings showed that the prevalence of insomnia among RT students in SA and the USA was found to be 32% and 21%, respectively. In addition, ISI scores were significantly higher among Saudi RT students who were female, in their second academic year, current smokers, single, and those with a poor cumulative GPA. However, ISI scores were significantly higher only among current smoker RT students in the USA. Conclusion: Insomnia was a prevalent sleep disorder among respiratory therapy students in both Saudi Arabia and the United States. Insomnia was negatively correlated with students' academic performance. Several demographic factors were significantly associated with a higher level of insomnia, including gender, academic year, smoking status, marital status, and GPA. Therefore, this study provides valuable insights for educational institutions and stakeholders to work collaboratively to implement tailored interventions and coping strategies that support students' healthy sleep habits, mental well-being, and academic achievement.

description: Genomic analyses from large cancer cohorts have revealed the mutational heterogeneity problem which hinders the identification of driver genes based only on mutation profiles. We present a novel edge-weighted random walk-based approach that incorporates connectivity information in the form of protein-protein interactions, mutual exclusivity, and coverage to identify cancer driver modules. MEXCOwalk outperforms several state-of-the-art methods on TCGA pan-cancer data in terms of recovering known cancer genes, providing modules that are capable of classifying normal and tumor samples, and that are enriched for mutations in specific cancer types. MEXCOwalk identifies modules containing both well-known cancer genes and putative cancer genes that are rarely mutated in the pan- cancer data.
