Visual Processing Impairment in Children With Suspected Auditory Processing Disorder: A Transdisciplinary Dimensional Approach to Diagnosis
Authors: Ahmmed Ansar U. , Asif Aysha , Winterburn Samantha 
Published: March 2022

Purpose:
The purpose of this study is to explore the utility of impairment(s) in language (LI), manual dexterity (IMD), and visual perceptual skills (IVPS) as a reference standard for diagnosing auditory processing disorder (APD).

Method:
Data from 104 participants with suspected APD (males = 57, females = 47; 6–16 years) were retrospectively analyzed. Index auditory processing (AP) tests included Auditory Figure Ground 0 dB, Competing Words–Directed Ear (CW-DE), and Time-Compressed Sentences (TCS). General Communication Composite (GCC) of the Children's Communication Checklist–2, manual dexterity (MD) component of the Movement Assessment Battery for Children–Second Edition, and Test for Visual Perceptual Skills–Third Edition (TVPS-3) were used to identify LI, IMD, and IVPS, respectively.

Results:
Eighty-one (77.8%), 58 (55.8%), and 37 (35.6%) participants had LI, IVPS, and IMD, respectively. Four factors explaining 67.69% of the variance were extracted. TVPS-3 (except visual closure [VClo]) represented the first; AFG 0, VClo, and MD the second; CW-DE and GCC the third; and TCS the fourth. APD diagnosed by combining AP tests and comorbidities had better accuracy compared to AP tests alone. The combined approach had overall diagnostic accuracy of 92.2%, 88.4%, and 81.7% for the 9th, 5th, and 2nd percentile AP test cutoffs, respectively.

Conclusions:
First-order AP tests in this study were related to language, MD, and visual perceptual skills. Given the overlap of LI, IMD, and IVPS with impaired AP, these comorbidities are an effective reference standard for APD. APD can be diagnosed following failing one AP test if one or more comorbidities exist. Ninth percentile AP test cutoff had better diagnostic accuracy compared to the currently used 2nd percentile cutoff.

Context. The identification and characterization of low surface brightness (LSB) stellar structures around galaxies such as tidal debris of ongoing or past collisions is essential to constrain models of galactic evolution. So far most efforts have focused on the numerical census of samples of varying sizes, either through visual inspection or more recently with deep learning. Detailed analyses including photometry have been carried out for a small number of objects, essentially because of the lack of convenient tools able to precisely characterize tidal structures around large samples of galaxies.
Aims. Our goal is to characterize in detail, and in particular obtain quantitative measurements, of LSB structures identified in deep images of samples consisting of hundreds of galaxies.
Methods. We developed an online annotation tool that enables contributors to delineate the shapes of diffuse extended stellar structures with precision, as well as artifacts or foreground structures. All parameters are automatically stored in a database which may be queried to retrieve quantitative measurements. We annotated LSB structures around 352 nearby massive galaxies with deep images obtained with the Canada-France-Hawaii Telescope as part of two large programs: Mass Assembly of early-Type GaLAxies with their fine Structures and Ultraviolet Near Infrared Optical Northern Survey/Canada-France Imaging Survey. Each LSB structure was delineated and labeled according to its likely nature: stellar shells, streams associated with a disrupted satellite, tails that formed in major mergers, ghost reflections, or cirrus.
Results. From our database containing 8441 annotations, the area, size, median surface brightness, and distance to the host of 228 structures were computed. The results confirm the fact that tidal structures defined as streams are thinner than tails, as expected by numerical simulations. In addition, tidal tails appear to exhibit a higher surface brightness than streams (by about 1 mag), which may be related to different survival times for the two types of collisional debris. We did not detect any tidal feature fainter than 27.5 magarcsec−2, while the nominal surface brightness limits of our surveys range between 28.3 and 29 magarcsec−2, a difference that needs to be taken into account when estimating the sensitivity of future surveys to identify LSB structures.
Conclusions. We compiled an annotation database of observed LSB structures around nearby massive galaxies including tidal features that may be used for quantitative analysis and as a training set for machine learning algorithms.
Subklinische Hypothyreose
Authors: Ruderich Franz , Feldkamp Joachim 
Published: March 2022

Was ist neu?
Definition und Epidemiologie Die subklinische Hypothyreose ist in der Regel eine Labordiagnose ohne signifikante Symptomatik und definiert durch ein erhöhtes TSH bei normalen Werten für freies T3 und freies T4. Bei Laborkontrollen nach 2–3 Monaten findet sich in 50 % der Fälle eine spontane Normalisierung.
Klinische Bedeutung der subklinischen Hypothyreose Bei persistierend erhöhten TSH-Werten ist die subklinische Hypothyreose mit dem Nachweis von schilddrüsenspezifischen Antikörpern im Sinne einer Autoimmunthyreoiditis assoziiert. Im Alter finden sich physiologisch höhere TSH-Spiegel. Es ist deshalb davon auszugehen, dass die Diagnose einer subklinischen Hypothyreose bei älteren Menschen über 70 Jahre zu häufig gestellt und therapiert wird.
Therapie der subklinischen Hypothyreose Studien konnten bisher keinen positiven Effekt einer Substitutionstherapie der subklinischen Hypothyreose zeigen, insbesondere nicht bei älteren Patienten. Andererseits besteht das nicht unerhebliche Risiko einer Übertherapie mit der Entwicklung einer subklinischen Hyperthyreose. Deren negative Folgen in Form von Vorhofflimmern und Osteoporose beeinträchtigen die Lebensqualität und -dauer. Bei der Indikationsstellung zur Substitutionstherapie einer subklinischen Hypothyreose sollte deshalb zurückhaltend vorgegangen werden.
Subklinische Hypothyreose in der Schwangerschaft Eine Gruppe, bei der Diagnostik und Therapie besondere Sensibilität erfordern, sind schwangere Frauen. Hier müssen mit Mutter und Kind 2 Individuen behandelt werden. Dabei sind veränderliche Zielwerte und Dosierungen bezogen auf das Schwangerschaftsalter zu berücksichtigen.

Published: March 2022

AbstractAn efficient synthetic method for coumarin derivatives was developed using a dual organocatalytic reaction. A combination of p-toluenesulfonic acid monohydrate and piperidine was found to efficiently catalyze the cyclization between salicylaldehydes and alkynoic esters to give various coumarin derivatives in good yield and high selectivity. Mechanistic and kinetic data suggested that the conjugate addition between piperidine and alkynoic esters played a crucial role in the reaction mechanism.

Published: March 2022

AbstractIntroduction Poor nutrition is a common finding in patients with acute leukemia, affecting disease progression, treatment outcome, and survival. Overall nutritional status and micronutrients status evaluation may be an important step in management of acute leukemia.Objective The objective of this study was to investigate baseline nutritional status, vitamin B12, and folate levels in patients with acute leukemia at the time of admission before starting chemotherapy and their initial treatment outcome.Materials and Methods This was a prospective observational study. We assessed the pretreatment nutritional status of 73 patients by body mass index (BMI), serum vitamin B12 using a two-step chemiluminescent microparticle immunoassay, and serum folate using electrochemiluminescence by Cobas e411 analyzer before initiation of induction chemotherapy and evaluated for treatment response at the end of induction chemotherapy.Results Out of a total of 73 patients, 51 (69.8%) completed induction chemotherapy, 36 (49.3%) showed complete remission, and 15 (20.5%) were in incomplete remission. Of the remaining 22 (30.1%) patients, 11 (15.1%) died due to toxicity during therapy. The mean values of baseline BMI, serum vitamin B12, and folate was 20.46 kg/m2, 956.04, and 13.52 ng/mL, respectively. There was no significant association between vitamin B12 (p-value = 0.609) and folate (p-value = 0.404) deficiency and the response to treatment.Conclusion Baseline nutritional status, serum vitamin B12, and folate levels have no significant role in induction outcome in response to treatment, including mortality in patients with acute leukemia.

Published: March 2022

AbstractThe objective of this study was to assess the risk of arterial thrombosis in patients who harbor the JAK2V617F allele burden ≥1% detected during workup for myeloproliferative neoplasms (MPNs). We conducted a large cross-sectional analysis consisted of 5,220 patients who were tested for JAK2V617F and 1,047,258 people matched in age from health care insurance provider, taking into account age, sex, hypertension, diabetes, atrial fibrillation. Compared with noncarriers, mutation carriers were older, less likely to be current or past smokers and had lower body mass index. There was no significant difference between the groups regarding myocardial infarction and peripheral vascular disease. However, JAK2V617F ≥1% at age 34 to 54 years was associated with eightfold more likely to have transient ischemic attack (TIA)/stroke history unrelated to hypertension, diabetes, or atrial fibrillation. Association of JAK2V617F with TIA/stroke was also observed in the older age group, albeit a weaker association and not statistically significant. Prevalence of TIA/stroke was higher in patients with JAK2V617F negative, with odds ratio of 3.93 when compared with the general population after confounder adjustments. Further research is warranted to verify the relation between allele burden of JAK2V617F mutation and TIA/stroke and the role of JAK2V617F per se as a risk factor for arterial thrombosis in the absence of overt MPN. Also, consideration should be paid to the screened group with JAK2V617F negative due to the high incidence of TIA/stroke among them in comparison to the general population.
Effect of oxygen incorporation on dynamic magnetic properties in Ta-O/Co-Fe-B bilayer films under out-of-plane and in-plane magnetic fields

Published: March 2022

Dynamic magnetic properties of Ta-O/Co20Fe60B20 bilayer films are strongly influenced by the oxidation condition of the Ta-O layer. The oxidation of the Ta-O layer by a slight amount of oxygen with a pressure (POxygen) of 0.03 Pa decreases in-plane damping constant (αIP), and increases the effective magnetization (4πMs,eff). Then, both αIP and 4πMs,eff maintain their values by increasing POxygen up to 0.3 Pa. The out-of-plane damping constant (αOP) showed a similar tendency to that of αIP against POxygen, although αOP is much smaller than αIP in every POxygen. αOP reaches to 0.0033 for sample oxidized at 0.03 Pa. It was suggested that αIP consists of both the intrinsic damping and the extrinsic damping, while αOP is closer to the intrinsic damping. The control of αOP and αIP by the oxidation would be beneficial in designing the high frequency spintronic devices.

Authors: Sumi Satoshi , Awano Hiroyuki , Tominaga Junji 
Published: March 2022

A [GeTe/Sb2Te3] superlattice is known as a topological insulator and it shows magnetic responses such as magneto-optical effect although it does not contain any magnetic element. We reported the superlattice has topologically protected spin diffusion length more than 100 μm at room temperature. In this paper, we show a laser induced spin injection to the superlattice using a TbFeCo film. We got spin injection signals between the TbFeCo and the Pt bars through the superlattice without electric current. The signals showed the maximum value of 0.06 μV around laser power of 1.0 mW which was focused to a spot diameter of 0.7 μm. The laser induced spin injection method will be one of the useful methods for future low-energy spintronics devices.

Abstract
In this article, we study the mass spectra of baryons containing two heavy quarks; charm-charm (cc) and bottom-charm (bc) with a light quark (u, d, s) within the framework of Regge phenomenology. With the assumption of linear Regge trajectories we have derived the relations between slope ratios, intercepts, and baryon masses. Using these relations, the ground state masses of Ξ

Detecting extragalactic diffuse interstellar bands (DIBs) in supernova spectra by using ESO data
Authors: Destiarasari A , Puspitarini L 
Published: March 2022

Abstract
Diffuse Interstellar Bands (DIBs) are weak and wide absorption features due to interstellar matter. DIBs are interesting to study because until now their chemical identifications are still unclear. DIBs can be found in reddened spectrum of celestial bodies in our Galaxy and other galaxies. Detecting extragalactic DIBs is challenging, one of the ways is by using an extragalactic supernova spectrum. The supernova acts as a background source to probe interstellar matter in a galaxy. We studied extragalactic DIBs by using the SN 2006X spectrum. The spectrum was observed by using the UVES instrument and the La Silla telescope at the European Southern Observatory (ESO) and was accessed from ESO archives. Detection of DIBs was performed by predicting the central wavelengths of DIBs in the supernova spectrum by taking the galaxy redshift (z) into account and observing DIBs profiles. Small shift variations in the wavelength are allowed. The detection of extragalactic DIBs indicates that DIBs are universal.
Null singularity on nonsingular spacetime
Authors: Pratama F. P. , Ramadhan H. S. 
Published: March 2022

Abstract
It is known that when coupled to nonlinear electrodynamics (NLED), Einstein’s equations can have nonsingular black hole (BH) solutions. For such BH the absence of horizon poses no violation of cosmic censorship theorem. In this work we show that the horizonless nonsingular BH charged with NLED, viewed from photon’s perspective, ironically is also responsible for the existence of singularity in its null geodesics. This is due to fact that the effective geometry gives additional conformal factor to the metric. For massive particles, on the other hand, the spacetime is still perfectly regular.

Published: March 2022

Abstract
A sample of 4 thousands Gaia sources with apparent G-band magnitudes of < 17 and trigonometric parallaxes of > 3.33 milli-arcseconds were cross-matched to the Transiting Exoplanet Survey high level science products and the Full-Frame Images in order to extract the light curves of possible white dwarf variables. Most of the targets in the sample were observed in at least 27-day observing cycle with 30-minutes cadence. Based on Lomb-Scargle periodogram constructed from de-trended light curves, more than 600 sources have indication of periodic variability. This paper presents the early results from the identification.

Published: March 2022

Abstract
Coronal holes are expansion regions in the solar corona with lower density and temperature than their surroundings. Coronal holes have open magnetic field structure that radiates out into interplanetary space as the solar wind. During minimum solar activity, coronal holes play important role in space weather because they are sources of high speed-streams. Therefore, studying the geo-effectiveness of coronal holes is very important. This paper presented a development of the coronal holes geo-effectiveness index related to the occurrence of geomagnetic storms. The index which was represented as “G(CH)”, is based on the combination of center position and cross-sectional length of coronal holes surface on latitudinal direction. Using 5 years of data of coronal holes (2015-2020), we analyzed the threshold combinations of the two parameters that can be used to scale the geo-effectiveness of a coronal hole. The results of all CH events with G(CH) > 0 should be considered as geomagnetic storm generator; CH events having the same characteristics as the CME event, i.e. although they have the potential to generate geomagnetic storms, the determining factor is influenced by the behavior and conditions of the solar wind and IMF Bz (-) during reconnection. So, the intensity of geomagnetic storm is strongly influenced by behavior and conditions (value and duration) both solar wind and Bz(-); the duration of CH event with G(CH) > 0 that have the potential to generate geomagnetic storms is a minimum of 6 days after the CH event; CH events accompanied by CIR affect the intensity and duration of the geomagnetic storms they generate, and the minimum value of G(CH) = 2.21.

Abstract
Development of the Decision Support Systems (DSS) has been written up in the Space Science Center’s roadmap for the next few years. The main programs have to be achieved such as related to the DSS are Space Weather, HF Radio Communication, Space Debris Monitoring, and Navigation activities. Of course, accessing those DSS services separately may become a problem for users who need information as fast as possible. We proposed an information system as a portal to integrate all DSS services collecting the latest information from each main program. We applied the microservice approach for design of this Information System prototype, which will it grows up as the modern application model that is capable to handle multiple features, high scalability but still lightweight. Microservices approach is a method that breaks an application into a single-function module for optimizing its performance. In addition, usage of web service technology and REST-ful API also can support system interoperability functions. In this design we conducted several stages, use case Diagrams, design of microservices database, and prototyping frontend pages in the results. This study purposes to provide an initial system design with a detailed explanation of specification requirements so that the design of the Decision Support System Service in the Space Science Center environment can be developed as expected.

Abstract
Natural rubber (NR) is known as one of the most important renewable agricultural resources in Thailand. To enhance the NR's value, development and utilization of NR in form of commercial product are necessary. Commercial product based on ultrafine fully vulcanized powdered rubber (UFPR) was widely used in numerous potential applications such as toughening filler or friction modifier in brake pads. However, to meet the required thermal stability of friction modifier in brake pads for replacing the synthetic rubber powder, the modification of NR by graft-copolymerization with styrene (ST) and acrylonitrile (AN) monomer and production into the powder form are promised related to a sustainable economic system. From the beginning, the grafting process of NR latex was prepared by emulsion graft-copolymerization with ST and AN monomers onto deproteinized natural rubber (DPNR). The results revealed that the grafting with ST/AN monomer content of 80/20 weight ratio possessed the monomer conversion and grafting efficiency as high as 71% and 63%, respectively. After that, the obtained DPNR-g-(PS-co-PAN) was radiated by an electron beam, followed by a spray drying process to produce ultrafine fully vulcanized powdered natural rubber (UFPNR-g-(PS-co-PAN)). The SEM micrographs showed that UFPNR particles are relatively spherical with a particle size of approximately 3.56 μm. Furthermore, thermal stability i.e., degradation temperature at 5 % weight loss (Td5) of the modified UFPNR was substantially improved from 334 to 350°C. The benefits of these advanced technologies give an obvious conclusion proved that the modified UFPNR is a good candidate for replacing a commercial synthetic powdered rubber and suitable for using as toughening filler in high performance polymer composite applications.
Thermoplastic natural rubber based on linear-low-density polyethylene
Authors: Yoksan R , Wannawitayapa W 
Published: March 2022

Abstract
Thermoplastic natural rubber (TPNR) is one of the alternative natural rubber (NR) products obtained by blending NR with any compatible thermoplastics, e.g., high-density polyethylene (HDPE), low-density polyethylene (LDPE), linear-low-density polyethylene (LLDPE), polystyrene (PS), polylactic acid (PLA) at the temperature above the melting point of plastics, which is always above the softening point of NR. Unlike vulcanized NR, TPNR is recyclable and convertible to the final articles using the existing plastic technologies, including extrusion and injection molding. TPNR materials based on NR/LLDPE blends filled with two types of inorganic fillers, i.e., titanium dioxide and silica, were prepared and their properties were discussed in the current work. Silica provided a better reinforcing effect to the NR/LLDPE blends, whereas the blends filled with titanium dioxide exhibited excellent UVA and weather resistance. The resulting NR/LLDPE blends filled with inorganic fillers can be injection molded to form the products with desired shapes.
