Low Regional Homogeneity of Intrinsic Cerebellar Activity in Ankle Instability: An Externally Validated rs-fMRI Study

ABSTRACT Purpose Joint deafferentation after post-ankle sprain ligament healing can disrupt sensory input from the ankle and induce maladaptive neuroplasticity, especially in the cerebellum. This study aimed to determine whether the regional homogeneity of intrinsic cerebellar activity differs between patients with ankle instability and healthy controls without a history of ankle injury. Methods The current study used a primary data set of 18 patients and 22 healthy controls and an external UK Biobank data set of 16 patients with ankle instability and 69 healthy controls for a cross-database, cross-sectional investigation. All participants underwent resting-state functional magnetic resonance imaging to calculate their regional homogeneity (ReHo) value. Between-group comparisons of the sensorimotor-related subregions of the cerebellum were first performed in the primary data set to identify low cerebellar ReHo in patients with multiple comparison corrections, and the surviving subregions were then externally validated in the UK Biobank data set. Correlation analyses between the ReHo values and clinical features were also performed. Results The ReHo value of cerebellar lobule VIIIb was significantly lower in the ankle instability group than in the controls (0.170 ± 0.016 vs 0.184 ± 0.019 in the primary data set, 0.157 ± 0.026 vs 0.180 ± 0.042 in the UK Biobank data set). The ReHo values of this subregion showed a significant positive correlation with the Cumberland Ankle Instability Tool scores in the ankle instability group (r = 0.553, P-corrected = 0.0348). Conclusions Patients with ankle instability had lower intraregional coherence in cerebellar lobule VIIIb than that of controls, which was also positively correlated with the intensity of self-reported ankle instability.
ON SIZES, KINEMATICS, M/L GRADIENTS, AND LIGHT PROFILES OF MASSIVE COMPACT GALAXIES AT z ∼ 2

We present a detailed analysis of the structure and resolved stellar populations of simulated merger remnants, and compare them to observations of compact quiescent galaxies at z ∼ 2. We find that major merging is a viable mechanism to produce systems of ∼1011 M☉ and ∼1 kpc size, provided the gas fraction at the time of final coalescence is high (∼40%) and provided that the progenitors are compact star-forming galaxies, as expected at high redshift. Their integrated spectral energy distributions and velocity dispersions are in good agreement with the observations, and their position in the (vmaj/σ, ϵ) diagram traces the upper envelope of the distribution of lower redshift early-type galaxies. The simulated merger remnants show time- and sightline-dependent M/L ratio gradients that result from a superposition of radially dependent stellar age, stellar metallicity, and extinction. The median ratio of the effective radius in rest-frame V-band light to that in mass surface density is ∼2 during the quiescent remnant phase. This is typically expressed by a negative color gradient (i.e., red core), which we expect to correlate with the integrated color of the system. Finally, the simulations differ from the observations in their surface brightness profile shape. The simulated remnants are typically best fit by high (n ≫ 4) Sérsic indices, whereas observed quiescent galaxies at z ∼ 2 tend to be less cuspy (〈n〉 ∼ 2.3). Limiting early star formation in the progenitors may be required to prevent the simulated merger remnants from having extended wings.
POSSIBLE ORIGIN OF RADIO EMISSION FROM NONTHERMAL ELECTRONS IN HOT ACCRETION FLOWS FOR LOW-LUMINOSITY ACTIVE GALACTIC NUCLEI

The two components of radio emission, above and below 86 GHz, respectively, from the Galactic center source Sgr A* can be naturally explained by the hybrid of thermal and nonthermal electrons in hot accretion flows (e.g., radiatively inefficient accretion flow; RIAF). We further apply this model to a sample of nearby low-luminosity active galactic nuclei (LLAGNs), which are also believed to be powered by RIAF. We selected LLAGNs with only compact radio cores according to high-resolution radio observations, and sources observed with jets or jet-like features are excluded. We find that the radio emission of LLAGNs is severely underpredicted by the pure RIAF model, but can be naturally explained by the RIAF model with a hybrid electron population consisting of both thermal and nonthermal particles. Our model can roughly reproduce the observed anticorrelation between the mass-corrected radio loudness and Eddington ratio for the LLAGNs in our sample. We further model the spectral energy distributions of each source in our sample and find that roughly all sources can be well fitted if a small fraction of the steady-state electron energy is ejected into the nonthermal electrons. The size of the radio emission region of our model is around several thousands of gravitational radii, which is also roughly consistent with recent high-resolution VLBI observations for some nearby LLAGNs.
Evidence of a first-order smectic-hexatic transition and its proximity to a tricritical point in smectic films

Experimental and theoretical studies of a smectic-hexatic transition in freely suspended films of 54COOBC compound are presented. X-ray investigations revealed a discontinuous first-order transition into the hexatic phase. Moreover, the temperature region of two phase coexistence near the phase transition point diminishes with film thickness. The coexistence width dependence on film thickness was derived on the basis of the Landau mean-field theory in the vicinity of the tricritical point (TCP). Close to TCP the surface hexatic ordering penetrates anomalously deep into the film interior.
Atomic Diagnostics of X-Ray-Irradiated Protoplanetary Disks

We study atomic-line diagnostics of the inner regions of protoplanetary disks with our model of X-ray-irradiated disk atmospheres, which was previously used to predict observable levels of the Ne II and Ne III fine-structure transitions at 12.81 and 15.55 μm. We extend the X-ray ionization theory to sulfur and calculate the fraction of sulfur in S, S+, S2 +, and sulfur molecules. For the D’Alessio generic T Tauri star disk, we find that the S I fine-structure line at 25.55 μm is below the detection level of the Spitzer Infrared Spectrometer (IRS), in large part due to X-ray ionization of atomic S at the top of the atmosphere and to its incorporation into molecules close to the midplane. We predict that observable fluxes of the S II λ6718/λ6732 forbidden transitions are produced in the upper atmosphere at somewhat shallower depths and smaller radii than the neon fine-structure lines. This and other forbidden-line transitions, such as the O I λ6300/λ6363 and C I λ9826/λ9852 lines, serve as complementary diagnostics of X-ray-irradiated disk atmospheres. We have also analyzed the potential role of the low-excitation fine-structure lines of C I, C II, and O I, which should be observable by SOFIA and Herschel.
Electronic structure of gold, aluminum, and gallium superatom complexes

Using ab-initio computational techniques on crystal determined clusters, we report on the similarities and differences of Al$_{50}$(C$_5$(CH$_3)_5)_{12}$, Ga$_{23}$(N(Si(CH$_3)_{3}$)$_{2}$)$_{11}$, and Au$_{102}$(SC$_7$O$_2$H$_5$)$_{44}$ ligand-protected clusters. Each of the ligand-protected clusters in this study show the similar stable character which can be described via a electronic shell model. We show here that the same type of analysis leads consistently to derive a superatomic electronic counting rule, independently of the metal and ligand compositions. One can define the cluster core as the set of atoms where delocalized single-angular-momentum-character orbitals have hight weight using a combination of Bader analysis and the evaluation of Khon-Sham orbitals. Subsequently one can derive the nature of the ligand-core interaction. These results yield further insight into the superatom analogy for the class of ligand-protected metal clusters.
Psychological processes in ritopsychotherapies of war psychotrauma in traditional Africa

Among some psychotraumatized Cameroonian soldiers of war, psychotherapeutic effects have been observed of the rites which they practiced on the return from the front. This observation favored the emergence of the concept of ritopsychotherapy, which is a rite-based psychotherapy.To this end, it was to explore the psychological processes implemented during these rites among the soldiers who benefited from them.The research was guided by the clinical method. The data were collected at the RAPHA-Psy Psychology Center, from five psychotraumatized soldiers of war through semi-structured interviews. The results highlighted seven main psychological processes in the five ritopsychotherapies explored. These are debriefing, catharsis, transference, suggestion, psychodrama, symbolic efficiency and psychoeducation. de guerre à travers des entretiens sémi-directifs. Les résultats ont mis en exergue sept principaux procédés psychologiques dans les cinq‘‘ritothérapies’’ explorées. Il s’agit du débriefing, de la catharsis, du transfert, de la suggestion, du psychodrame, de l’efficacité symbolique et de la psychoéducation.
Binary logistic regression model applied to data on accidents occurred on federal highways in Brazil

Accidents on federal highways in Brazil lead to social and economic impacts on the country. Data from the Federal Highway Police reveal that thousands of people lose their lives in these accidents year after year. This paper aims to examine the factors that influence the probability of death based on the occurrence of the accident. The estimation of a binary logistic regression model took place, in which the event of interest is the circumstance of death in an accident with data from 2021. Following variable selection procedures, it was possible to obtain the final model, which was later validated with data from 2022. The accuracy of the model for both 2021 and 2022 data was around 70%. Then, the odds ratio was calculated between some distinct categories, and how much of an increase in accident lethality it generates compared to the reference category. For example, in a crash, a pedestrian is 15.6 times more likely to die when compared to the driver, while a cyclist is 5.3 times more likely to die. Although most accidents have a human cause, some results show the need of public policies that can help reduce these tragedies. To explain the model, a dashboard was created in a way that the user is able to obtain the probability of death by selecting specific accident characteristics and those involved.
A Review on reliability of Android goniometer and Traditional goniometer

The brief investigation focuses on the impact of the goniometer that is android goniometer or traditional goniometer.Which formerly check the degree of motion of the joints. Which eventually results in the more accurate and easy use of goniometer. To determine the joint mobility . Physical therapists routinely utilize goniometers to assess range-of-motion (ROM) in the musculoskeletal system. These measureshave been utilized to aid in the treatment and to evaluate therapeutic performance. Smartphone-based apps for sensing joint angles and movement are being investigated using newly developing technology. (1)The traditional goniometer is a typical technique for evaluating the degree of movement . Also it possibly have various limitations, such as the physician’s participation of both hands, this leads to hand instability and inaccuracy. Because of their ease of use, smartphones are becoming extremely popular. (2)According to the study, two very different approaches can be used to identify Full range of motion and also the variation in information taken by methods is less than 3.4 percent. (3)
Simplifying multiloop integrands and ultraviolet divergences of gauge theory and gravity amplitudes

We use the duality between color and kinematics to simplify the construction of the complete four-loop four-point amplitude of N = 4 super-Yang-Mills theory, including the nonplanar contributions. The duality completely determines the amplitude's integrand in terms of just two planar graphs. The existence of a manifestly dual gauge-theory amplitude trivializes the construction of the corresponding N = 8 supergravity integrand, whose graph numerators are double copies (squares) of the N = 4 super-Yang-Mills numerators. The success of this procedure provides further nontrivial evidence that the duality and double-copy properties hold at loop level. The new form of the four-loop four-point supergravity amplitude makes manifest the same ultraviolet power counting as the corresponding N = 4 super-Yang-Mills amplitude. We determine the amplitude's ultraviolet pole in the critical dimension of D = 11/2, the same dimension as for N = 4 super-Yang-Mills theory. Strikingly, exactly the same combination of vacuum integrals (after simplification) describes the ultraviolet divergence of N = 8 supergravity as the subleading-in-1/N{sub c}{sup 2} single-trace divergence in N = 4 super-Yang-Mills theory.
The use of collagen type-II as an indicator for assessment regeneration effect post intra-articular pure-PRP injection in KOA patient

Background: knee osteoarthritis (KOA) is a complex disease that causes metabolic, structural, biochemical, and functional al-terations in afflicted tissues. Physical examination and radiological findings are the present methods for the diagnosis of knee osteoarthritis. Traditionally, KOA medication focused on symptom management. Clinical trials focused on delaying or reversing disease development have gained popularity in recent years. PRP is among the medicinal approaches used to manage KOA.Purpose: By assessing the cartilage degradation marker collagen-II, the study’s aim was to figure out whether the use of pure-PRP may help KOA patients’ damaged cartilage layers regenerate. Methods: This non-randomized controlled trial study involved 66 patients with knee OA and 28 healthy control subjects from December 2021 to February 2022. There were 2 categories of knee OA patients: 34 with moderate (grade-3) and 32 with mild (grade-2) KOA. So, every group of KOA patients is divided into three subgroups based to the frequency of injections (single, double, or triple) in addition to severity. Based on clinical and radiological data using the Kellgren-Lawence (KL) 0–4 grading system, the patients’ diagnoses and classifications are made. This study was designed at AL-Imam Ali hospital, Babylon governorate, Iraq and approved by the medical human research ethics committee at Al-Qadisiyah university/ collage of medicine. Result: The findings of this investigation show that the serum collagen type-II content was considerably greater in KOA patients were compared to control subjects, and in moderate compared to mild KOA as the severity of the disease progressed. But following pure-PRP injection, the serum level of collagen type-II did not significantly decrease, and increasing the number of injections had no better effect. Conclusions: PRP therapy was generally acceptable for patients in terms of improving symptoms and there were no com-plications following injection. However, there is insufficient indication that platelet rich plasma regenerates cartilage damage in knee OA patients, as there was no significant decrease in the amount of collagen type-II.
The influence of weak lensing on measurements of the Hubble constant with quad-image gravitational lenses

We investigate the influence of matter along the line of sight and in the strong lens vicinity on the properties of quad image configurations and on the measurements of the Hubble constant (H0). We use simulations of light propagation in a nonuniform universe model with the distribution of matter in space based on the data from Millennium Simulation. For a given strong lens and haloes in its environment we model the matter distribution along the line of sight many times, using different combinations of precomputed deflection maps representing subsequent layers of matter on the path of rays. We fit the simulated quad image configurations with time delays using nonsingular isothermal ellipsoids (NSIE) with external shear as lens models, treating the Hubble constant as a free parameter. We get a large artificial catalog of lenses with derived values of the Hubble constant, Hfit. The average and median of Hfit differ from the true value used in simulations by < 0.5 km/s/Mpc which includes the influence of matter along the line of sight and in the lens vicinity, and uncertainty in lens parameters, except the slope of the matter distribution, which is fixed. The characteristic uncertainty of Hfit is ~3 km/s/Mpc. Substituting the lens shear parameters with values estimated from the simulations reduces the uncertainty to ~2 km/s/Mpc.
No Open Cluster in the Ruprecht 93 Region

UBVI CCD photometry has been obtained for the Ruprecht 93 (Ru 93) region. We were unable to confirm the existence of an intermediate-age open cluster in Ru 93 from the spatial distribution of blue stars. On the other hand, we found two young star groups in the observed field: the nearer one (Ru 93 group) comprises the field young stars in the Sgr-Car arm at d ~ 2.1 kpc, while the farther one (WR 37 group) is the young stars around WR 37 at d ~ 4.8 kpc. We have derived an abnormal extinction law (Rv = 3.5) in the Ruprecht 93 region.
An Equation-Free Approach for Second Order Multiscale Hyperbolic Problems in Non-Divergence Form

The present study concerns the numerical homogenization of second order hyperbolic equations in non-divergence form, where the model problem includes a rapidly oscillating coefficient function. These small scales influence the large scale behavior, hence their effects should be accurately modelled in a numerical simulation. A direct numerical simulation is prohibitively expensive since a minimum of two points per wavelength are needed to resolve the small scales. A multiscale method, under the equation free methodology, is proposed to approximate the coarse scale behaviour of the exact solution at a cost independent of the small scales in the problem. We prove convergence rates for the upscaled quantities in one as well as in multi-dimensional periodic settings. Moreover, numerical results in one and two dimensions are provided to support the theory.
PROBING THE PRE-REIONIZATION EPOCH WITH MOLECULAR HYDROGEN INTENSITY MAPPING

Molecular hydrogen is now understood to be the main coolant of the primordial gas clouds leading to the formation of the very first stars and galaxies. The line emissions associated with molecular hydrogen should then be a good tracer of the matter distribution at the onset of the reionization of the universe. Here, we propose intensity mapping of H2 line emission in rest-frame mid-infrared wavelengths to map out the spatial distribution of gas at redshifts z > 10. We calculate the expected mean intensity and clustering power spectrum for several H2 lines. We find that the 0–0S(3) rotational line at a rest wavelength of 9.66 μm is the brightest line over the redshift range of 10–30 with an intensity of about 5–10 Jy sr−1 at z ∼ 15. To reduce astrophysical and instrumental systematics, we propose the cross-correlation between multiple lines of the H2 rotational and vibrational line emission spectrum. Our estimates of the intensity can be used as guidance in planning instruments for future mid-IR spectroscopy missions such as SPICA.
Transient current-current correlations and noise spectra

In this paper, we present an exact formalism for transient current-current correlations and transient noise spectra. The exact solution of transient current correlations in both the time domain and the frequency domain are obtained. Without taking the wide band limit, we investigate transient current-current correlations with different bias voltages and different finite temperatures. Transient noise spectra over the whole frequency range are calculated and that in the steady-state limit are also reproduced. From transient current-current correlations and noise spectra, we analyze the frequency-dependence of electron transport for the system evolving far away from equilibrium to the steady state. Various time scales associated with the energy structure of the nanosystem are also obtained from the transient current-current correlations and transient noise spectra.
The evaluation of cochlear implant users’ acoustic change detection ability

Abstract Objectives This study aimed to evaluate the relationship between behaviourally acquired Acoustic Change Detection Test (ACDT) responses and electrophysiologically obtained Acoustic Change Complex (ACC) responses in participants with Cochlear Implant (CI). Methods 28 unilateral adult CI users (mean age 41) participated in the study. In behavioural test session, ACDT and speech tests were administered. In electrophysiological test session, sound onset and ACC responses of participants stimulated by/ui/speech structure were recorded and N1–P2 peak-to-peak amplitude and N1 latencies were determined. Results No significant correlation was found between individuals’ behavioural and electrophysiological responses but it was observed that individuals dived into two clusters in terms of ACDT responses (p < 0.05). A statistically significant difference was found between the mean ACC amplitudes of the clusters. No statistically significant difference was observed between the mean ACC N1 latency findings of the clusters, suggesting that ACC amplitude may be a better predictor than latency in auditory discrimination. Conclusion ACC measurement may be a potential clinical tool to evaluate auditory discrimination performance in individuals with CI, but using the electrophysiological and behavioural tests together may provide a more holistic perspective.
Theory of Radio Frequency Spectroscopy of Polarized Fermi Gases

We present two exact results for singular features in the radio frequency intensity $I(\omega)$ for ultracold Fermi gases. First, in the absence of final state interactions, $I(\omega)$ has a universal high frequency tail $ C\omega^{-3/2}$ for \emph{all} many-body states, where $C$ is Tan's contact. Second, in a \emph{normal} Fermi liquid at T=0, $I(\omega)$ has a jump discontinuity of $Z/(1 - m/m^{*})$, where $Z$ is the quasiparticle weight and $m^*/m$ the mass renormalization. We then describe various approximations for $I(\omega)$ in polarized normal gases. We show why an approximation that is exact in the $n_\dn=0$ limit, fails qualitatively for $n_{\dn} > 0$: there is no universal tail and sum rules are violated. The simple ladder approximation is qualitatively correct for very small $n_{\dn}$, but not quantitatively.
Stability and periodicity in the modular representation theory of symmetric groups

We study asymptotic properties of the modular representation theory of symmetric groups and investigate modular analogs of stabilization phenomena in characteristic zero. The main results are equivalences of categories between certain abelian subcategories of representations of $S_n$ and $S_m$ for different $n$ and $m$. We apply these results to obtain a structural result for $FI$-modules, and to prove a result conjectured by Deligne in a recent letter to Ostrik.
