Cortical and cerebellar structural correlates of cognitive-motor integration performance in females with and without persistent concussion symptoms

ABSTRACT Introduction Fifteen percent of individuals who sustain a concussion develop persistent concussion symptoms (PCS). Recent literature has demonstrated atrophy of the frontal, parietal, and cerebellar regions following acute concussive injury. The frontoparietal-cerebellar network is essential for the performance of visuomotor transformation tasks requiring cognitive-motor integration (CMI), important for daily function. Purpose We investigated cortical and subcortical structural differences and how these differences are associated with CMI performance in those with PCS versus healthy controls. Methods Twenty-six age-matched female participants (13 PCS, 13 healthy) completed four visuomotor tasks. Additionally, MR-images were analyzed for cortical thickness and volume, and cerebellar lobule volume. Results No statistically significant group differences were found in CMI performance. However, those with PCS demonstrated a significantly thicker and larger precuneus, and significantly smaller cerebellar lobules (VIIIa, VIIIb, X) compared to controls. When groups were combined, volumes of both the cerebellar lobules and cortical regions were associated with CMI task performance. Conclusion The lack of behavioral differences combined with the structural differences may reflect a compensatory mechanism for those with PCS. In addition, this study highlights the effectiveness of CMI tasks in estimating the structural integrity of the frontoparietal-cerebellar network and is among the first to demonstrate structural correlates of PCS.
Soapnut shell powder as immunomodulatory and welfare friendly feed additive in broiler chicken

With growing awareness for safe and clean poultry products among consumer, the industry faces a tough challenge of antibiotic free as well as welfare friendly poultry farming. This study was conducted to evaluate the efficacy of soapnut shell powder, rich in saponins, as immune enhancer and stress reliever in broiler chicken. The broiler chicks were randomly distributed into four dietary treatments, viz. T1 (basal diet, control), T2 (basal diet with 100 mg saponin/kg diet), T3 (basal diet with 150 mg saponin/kg diet), and T4 (basal diet with 200 mg saponin/kg diet) and reared up to 42 days of age. The results revealed that supplementing saponin level beyond 100 mg/kg diet significantly reduced body weight gain and feed intake of birds at 4th and 5th week of age with no significant effect on the FCR. The cell mediated and humoral immunity of birds also improved due to saponins @ 100 mg/kg diet or above. However, no significant dietary effects were observed on the weight of immune organs. Similarly, the abdominal fat (%) and H:L ratio of birds significantly decreased at 100 mg saponin level indicating the stress relieving effect of saponins. The study concluded that dietary supplementation of saponins (100 mg/kg diet) in the form of soapnut shell powder not only enhances the immunity but also improves the welfare of birds without affecting feed efficiency. Thus, soapnut shell powder can be used as an alternative option for the antibiotic free broiler chicken production especially in hilly areas where it is cheaply available.
Metaphors in Abstract Thought

textabstractThe aim of the dissertation was to investigate the Conceptual Metaphor Theory (CMT, Lakoff & Johnson, 1980, 1999). The CMT proposes that abstract concepts are partly structured by concrete concepts through the mechanism of metaphorical mapping. In Chapter 2 we wanted to investigate the role of the vehicle (concrete concept) in the comprehension process of the topic(abstract concept) in a metaphorical sentence, but we found mixed results. In Chapter 3 to Chapter 6 we investigated the role of concrete concepts during conceptual tasks about abstract concepts. Chapter 3 shows that participantsâ€™ performance over a similarity decision task (similar or dissimilar colours) was influenced by the distance of presentation (near or far) in congruence with the conceptual metaphor (similar is near and dissimilar is far). Chapter 4 shows that participantsâ€™ performance over a categorization task (same category vs. different category) on pictures (animals or vehicles) was influenced by the position of a frame (both pictures in or one out of the frame) in congruence with the conceptual metaphor (same category is in container and different category is out of container). Chapter 5 showed evidence that situational quantity (e.g., 5 bananas) was partly represented by verticality (more is up and less is down) but simple numbers (e.g., 5) not. Chapter 6 could not show evidence that love is partly represented by warmth or closeness. In conclusion, the studies in this thesis partly support the CMT.
One‐step local quasi‐likelihood estimation

Local quasi‐likelihood estimation is a useful extension of local least squares methods, but its computational cost and algorithmic convergence problems make the procedure less appealing, particularly when it is iteratively used in methods such as the back‐fitting algorithm, cross‐validation and bootstrapping. A one‐step local quasi‐likelihood estimator is introduced to overcome the computational drawbacks of the local quasi‐likelihood method. We demonstrate that as long as the initial estimators are reasonably good, the one‐step estimator has the same asymptotic behaviour as the local quasi‐likelihood method. Our simulation shows that the one‐step estimator performs at least as well as the local quasi‐likelihood method for a wide range of choices of bandwidths. A data‐driven bandwidth selector is proposed for the one‐step estimator based on the pre‐asymptotic substitution method of Fan and Gijbels. It is then demonstrated that the data‐driven one‐step local quasi‐likelihood estimator performs as well as the maximum local quasi‐likelihood estimator by using the ideal optimal bandwidth.
The peculiar velocity field in the Perseus-Pisces supercluster

Results are reported from a program to study peculiar motions of galaxies in the Per-Psc supercluster. The data set consists of newly obtained CCD photometry and published 21-cm line widths for 320 spiral galaxies. The peculiar velocities of these objects are estimated using the Tully-Fisher relation, calibrated with respect to an independent sample of cluster galaxies. Analysis shows that the principal feature of the velocity field in the Per-Psc region is a coherent streaming toward the Local Group. Nearly all the galaxies well in the foreground (cz less than about 2000 km/sec) have negtive peculiar velocities of amplitude about 1000 km/sec. A great majority of objects in the background of the supercluster, out to redshifts of about 7000 km/sec, also have very large negative peculiar velocities. The supercluster ridge itself, at a redshift or about 5000 km/sec, appears to consist of positive and negative peculiar-velocity groups of galaxies, but with negative peculiar velocities predominating both in amplitude and in number of objects involved. 14 refs.
Spectroscopy of globular clusters in M87 and M49

Optical multislit spectra of globular clusters in two giant elliptical galaxies in the Virgo Cluster indicate average metal abundances of one-sixth and one-tenth solar composition for M49 and M87, respectively. These estimates are based on the strength of Mg lines. Taken together with observations of globular clusters in dwarf ellipticals this suggests a direct relation between mean metallicity of the cluster system and the luminosity of the parent galaxy which is an interesting constraint on theories of cluster formation during the protogalactic epoch. Rotation is evident in both globular cluster systems. The line-of-sight velocity dispersions of clusters in the two galaxies are estimated to be 340 + or - 50 km/s (M49) and 386 + or - 42 km/s (M87). Although sparsely sampled, the velocity dispersion profiles of the cluster systems are flat, suggesting the existence of an isothermal halo of dark matter in these ellipticals. 37 refs.
Virulence, Antibiotic Resistance, and Phylogenetic Relationships of Aeromonas spp. Carried by Migratory Birds in China

This study aimed to evaluate antimicrobial resistance, virulence, and the genetic diversity of Aeromonas isolated from migratory birds from Guangxi Province, Guangdong Province, Ningxia Hui Autonomous Region, Jiangxi Province, and Inner Mongolia in China. A total of 810 samples were collected, including fresh feces, cloacal swabs, and throat swabs. The collected samples were processed and subjected to bacteriological examination. The resistance to 21 antibiotics was evaluated. A phylogenetic tree was constructed using concatenated gltA-groL-gyrB-metG-PPSA-recA sequences. Eight putative virulence factors were identified by PCR and sequencing, and a biofilm formation assay was performed using a modified microtiter plate method. In total, 176 Aeromonas isolates were isolated including A. sobria, A. hydrophila, A. veronii, and A. caviae. All isolates showed variable resistance against all 16 tested antibiotic discs, and only one antibiotic had no reference standard. Six kinds of virulence gene markers were discovered, and the detection rates were 46.0% (hlyA), 76.1% (aerA), 52.3% (alt), 4.5% (ast), 54.0% (fla), and 64.2% (lip). These strains were able to form biofilms with distinct magnitudes; 102 were weakly adherent, 14 were moderately adherent, 60 were non-adherent, and none were strongly adherent. Our results suggest that migratory birds carry highly virulent and multidrug-resistant Aeromonas and spread them around the world through migration, which is a potential threat to public health.
Parameter estimation with Bayesian estimation applied to multiple species in the presence of biases and correlations

The original formulation of Bayesian estimation applied to multiple species (BEAMS) showed how to use a data set contaminated by points of multiple underlying types to perform unbiased parameter estimation. An example is cosmological parameter estimation from a photometric supernova sample contaminated by unknown Type Ibc and II supernovae. Where other methods require data cuts to increase purity, BEAMS uses all of the data points in conjunction with their probabilities of being each type. Here we extend the BEAMS formalism to allow for correlations between the data and the type probabilities of the objects as can occur in realistic cases. We show with simple simulations that this extension can be crucial, providing a 50 per cent reduction in parameter estimation variance when such correlations do exist. We then go on to perform tests to quantify the importance of the type probabilities, one of which illustrates the effect of biasing the probabilities in various ways. Finally, a general presentation of the selection bias problem is given, and discussed in the context of future photometric supernova surveys and BEAMS, which lead to specific recommendations for future supernova surveys.
Authentic Leadership and Organizational Identification: Its Relation to Organizational Silence and Cynicism among staff nurses

: Background: Authentic leadership, as the key component of productive leadership, which is necessary to create healthier workplace. These actions are concordant with innately held nursing values to demonstrate trust and independence, reflecting staff identification with their organization and diminishing negative behaviors such as silence and cynicism for organizational efficiency. The study aimed to assess authentic leadership and organizational identification and its relation to organizational silence and cynicism among staff nurses. Research design: A descriptive correlational design was used. Setting: All the Critical Care units of Benha University Hospital were used for conducting the study. Subjects: A simple random sample of (275) staff nurses who met the criteria for inclusion. Tools: There four tools were used for data collection 1) Authentic Leadership Questionnaire (ALQ), 2) Organizational Identification Questionnaire (QIQ), 3) Organizational Silence Scale & 4) Organizational Cynicism Scale (OCS). Results: The majority (90.6% and 73.5%) of staff nurses reported high perceived authenticity levels and organizational identification levels were high respectively, while about two-thirds and the majority (62.9% and 82.6%) of them had low levels respectively for organizational silence and cynicism at the studied setting. Conclusion: There was a highly positive statistically significant correlation between (authentic leadership and organizational identification), also, between (organizational silence and cynicism) among staff nurses at (P value < 0.01). There was a highly negative statistically significant correlation among authentic leadership, organizational identification, organizational silence and cynicism. Recommendation: strengthen their competitive edge by attracting and retaining leaders who act on their own to complete their tasks and assist other staff. Adopt an open-door policy to overcome work problems.
Atomic layer deposited Al2O3 for gate dielectric and passivation layer of single-walled carbon nanotube transistors

High performance single-walled carbon nanotube field effect transistors (SWCNT-FETs) fabricated with thin atomic layer deposited (ALD) Al2O3 as gate dielectrics and passivation layer are demonstrated. A 1. 5μm gate-length SWCNT-FETs with 15nm thick Al2O3 insulator shows a gate leakage current below 10−11A at −2.5V<Vg<+7V, a subthreshold swing of S∼105mV∕decade, and a maximum on current of −12μA at a reverse gate bias of −1V. Lack of hysteresis in IV characteristics and low low frequency noise indicate high quality oxide-nanotube interface achieved utilizing ALD Al2O3 as gate dielectrics and passivation layer.
Parental Emotional Availability and Family Functioning in Adolescent Anorexia Nervosa Subtypes

Emotional availability (EA) is a complex construct describing the emotional bond between parents and child, and it refers to support, sensitivity, warmth and closeness. Few studies have investigated the perception of parental EA and its association with dysfunctional eating pattern. The aim of the study is to explore the perception of mothers’ and fathers’ EA of adolescents with anorexia nervosa (AN) and any differences between the two subtypes of binge–purge (B/P) or restrictive (R) AN. Furthermore, it investigates the association of parental EA with AN symptomatology and with patients’ perception of family functioning, which is identified as a maintenance factor for AN. A total of 60 adolescents between 12 and 18 years and their parents (n = 120) were recruited in two eating disorder (ED) specialized care centers. Patients completed the LEAP and the FACES IV questionnaires evaluating parental EA and family functioning, respectively. Results showed no difference between AN subtypes, but a greater perception of mother when compared to father EA was found. Moreover, the EA construct was found not to be associated with ED symptomatology but with a greater positive family functioning. Our study is the first that explores EA in AN, and results suggest the importance of considering parents’ emotional engagement as part of the treatment core, together with the eating symptomatology management.
Magnetic Properties of Some Ferrite Micropowders

Micropowders of stoichiometric copper, nickel, and cobalt ferrites were prepared by low temperature ( 2000 A. Particle sizes were determined from x‐ray line broadening and from electron micrographs.The micropowders exhibited superparamagnetic, single domain, or multidomain behavior depending on the particle size. The critical size for single domain behavior, depending on composition, was between 300 and 700 A. In this size range, high coercive force and remanence were observed in spite of appreciable sintering of the particles in some cases. The remanence values and the magnitude and temperature dependence of the coercive force indicated that magnetocrystalline anisotropy determined the properties of the single domain particles. The magnetic properties of the very small particle size samples showed the large temperature depende.
Management of no Reflow during Percutaneous Transcoronary Angioplasty with Catheter-Directed Intracoronary Thrombolysis: A Retrospective Observational Study

Abstract Background: Intracoronary thrombus is common in patients with ST-elevation myocardial infarction (STEMI). Percutaneous coronary intervention (PCI) is the treatment of choice for these patients. Intracoronary thrombus is still a challenge during PCI in STEMI, even with dual antiplatelets, glycoprotein IIb/IIIa inhibitor, and anticoagulation. Intracoronary thrombus can cause distal or nonculprit vessel embolization and no-reflow state. No reflow results in large infarct size, adverse left ventricular remodeling, arrhythmias, and death. Recently, catheter-directed intracoronary thrombolysis (ICT) is gaining acceptance in patients with no-reflow due to a large thrombus burden. Aim: Evaluation of catheter-directed ICT in patients with acute STEMI who develop no reflow due to large thrombus burden during PCI. Materials and Methods and Results: This was a retrospective observational study conducted after approval of the institutional ethics committee in a tertiary care hospital of north India from April 15, 2021 to April 14, 2022, included 1020 adult patients who had undergone coronary evaluation. 37.25% patients had PCI, among these 10% had PCI for acute STEMI. Thrombolysis in myocardial infarction (TIMI) Grade 5 in 79.17% and Grade 4 in 20.83%. ICT was done with low-dose tenecteplase (15 ± 5 mg). The TIMI flow III in 91.67% and II in 8.33% of patients was achieved after intracoronary thrombolysis. Major risk factor was tobacco smoking in 41.67%, and the major complication was left ventricular failure in 33.33%. Conclusions: Catheter-directed ICT is safe and effective in reducing thrombus burden, thus improving myocardial reperfusion in STEMI. This condition has a grave prognosis and can lead to adverse cardiac outcomes. There are many drugs that have been tried to manage no reflow. The use of ICT to treat no-reflow state can be life saving with minimal systemic side effects.
Driven dissipative whistler wave turbulence

Driven dissipative whistler wave turbulence in two-dimensional electron magnetohydrodynamics is investigated using very high resolution nonlinear fluid simulations. It is shown that a dual cascade phenomenon of mean magnetic potential and energy invariants is in agreement with predictions based on statistical ensemble and Kolmogorov’s theories. Turbulent length scales larger than the electron skin depth (whistler wave regime) exhibit a spectral break in the vicinity of the forcing wave number that separates the inverse and forward cascade regimes. On the other hand, length scales smaller than the electron skin depth behave like hydrodynamic eddies in which both small and large scale regimes exhibit identical turbulent spectra. In both cases, however, turbulent fluctuations follow an exact Kolmogorov-type spectra. While wave effects are strong in the whistler wave regime, they are absent entirely in the hydrodynamics regime of the driven electron magnetohydrodynamic turbulence.
Robust Nonlinear Control of Parametric Uncertain Systems With Unknown Friction and Its Application to a Pneumatic Control Valve

A robust nonlinear control approach is presented for parametric uncertain systems with unknown friction. First- and second-order systems are considered, respectively. A model reference controller is developed such that the tracking error is bounded and converges to zero in the presence of the parameter uncertainty and the unknown friction. Then, the controller is extended to general case with any order. To design the controller, exact friction force is not required, only the upper bound for the level. Lyapunov's direct method is used to prove robust global convergence of the tracking error. Finally, experimental results are given by applying the proposed controller to a pneumatic control valve.
The Concept of Fertility in the Dakhleh Oasis, Cult and Symbolism

صلختسملا This study examines the opinion of the oasis’ dwellers about their environment which differs from the perception of the dwellers outside the oasis. The local cult of fertility in Dakhleh attested by the worship of Seth as a protector and fertility god, IsisDemeter as a goddess of agriculture, Amun-Re as Min of Akhmim who cultivate the lands and God Tutu as a protector and controller of the waters. The source of the subterranean water (wells) in the Oasis was the Nile and the iconography of the water wells were Gods Khnum Re and Isis-Sothis were the controller of the first cataract of the Nile, God Osiris controller to the source of the water at the Oasis, God Amun Nakht who protect and control water in the Oasis. The iconography of the inundation was the fecundity figure of Hapy, and the iconography of the inundated land was the female fecundity figure of Sekhet. فلتخي يتلاو مهتئيب يف ةلخادلا ةحاو ناكس يأ ر يف ةسا ردلا هذه ثحبت . ةحاولا جراخ ناكسلا نع اهموهفم لا ةدابع ةبوصخلل ةيلحملا ةحاو يف ةدابع قيرط نع اهديكأت مت ةلخادلا هللإا تس هلإك ةبوصخلل هلإو يماح . ا كلذكو للإ سيزيإ ةه رتيميد هللإاو ةعا رزلل ةهلإك عر نومآ دبع يذلاو وتوت هللإا كلذكو ،يضا رلأا بصخي يذلاو )ميمخأ( نيم هللإا ةروص يف وؤسملاو نؤملل يماح هلإك ل ةحاولاب هايملا نع قلعتي اميف امأ . ب هايملا ةيفوجلا )رايبلأا( يف ةحاو ،ةلخادلا تناك دقو ،لينلا رهن وه اهردصمف لا هايملا رابآ ةئيه ىلع نييلحملا ناكسلا رظن ةهجو نم ةحاولا يف ةيفوج هللإا نم لًاك مونخ سيزيإ ةهللأاو عر سيثوس نع نلاؤسملا امهو نع لوؤسملاو اًضيأ مكحتملاو سيريزوأ هللإاو ،لينلا رهنل لولأا للاشلا نومآ هللإاامأ ،ةحاولاب هايملا ردصم يف مكحتمو يماح هلإ وهف تخن حاولاب هايملا ناضيف ليثمت نع امأ . ةحاولاب هايملا رابآ لثمي مهعيمجف ،ة سيزيإ هللإا امأ ،ةبوصخلا لاكشأ نم لكشك يباح ناك دقف لينلا تخس . ناضيفلا هايمب ةاطغملا ضرلأا لثمتو اًضيأ ةبوصخ ةئيه يف تناكف
Higher Approximate Solutions of the Duffing Equation : Primary Resonance in the Soft Spring System

The Duffing system with soft spring is analysed by using a new algorithm which computes nonlinear steady-state oscillations and their stability with high speed and accuracy, based on the lines of the harmonic balance method. Detailed results of the frequency response of the primary resonance, up to the 9th harmonics, are presented. The following are demonstrated : a new unstable region, an isolated branch, the bifurcation of the non-odd order solutions, subharmonic oscillations (order 1/2 and 1/4), random almost periodic oscillations and superharmonic resonances (order 2 to 7). Some of these are confirmed by numerical simulation.
Magnetic fields in late-type galaxies

Magnitudes of the volume-averaged magnetic field have been derived for a representative sample of 146 late-type galaxies using the minimum-energy condition and a simple model for the distribution of radio-emitting plasma within these galaxies. The distribution of derived magnetic fields is narrow (B eq = 0.29 ± 0.11 nT) and skewed to higher values. There is little or no dependence of the derived magnetic field on galactic type, although the archetypal starburst M82 is anomalous. We find no correlation between the scatter in the far-infrared/radio correlation and variation in the derived strength of the magnetic field
