Can Neutrophil-Lymphocyte and Platelet-Lymphocyte Ratios Predict the Risk of Developing New Ischemic Lesions After Carotid Stenting?
Authors: YABALAK Ahmet , ÖĞÜN Muhammed Nur
Published: June 2023

Aim: It has been reported that the neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) are associated with carotid artery stenosis rate, risk of restenosis after stenting, and clinical outcome after an ischemic stroke, and are also predictive markers. The objective of this study is to evaluate whether NLR and PLR values and the associated temporal changes are indicators of the risk for newly developing ischemic lesions.
Material and Methods: Patients who underwent stenting in our clinic between November 2019 and January 2022 and who had a complete blood count and a diffusion magnetic resonance imaging scan before and after the procedure, were included in the study and evaluated in two groups; patients with and without newly developing ischemic lesions.
Results: Newly developing ischemic lesions were detected in 27 of the 50 patients included in the study. There was no difference in baseline and 48th-hour NLR and PLR rates and the temporal variation of these rates between patients with and without newly developing ischemic lesions. Erythrocyte distribution width (RDW) and hemoglobin (HGB) values were higher in the without newly developing ischemic lesions group at 48 hours, but there was only a significant difference between the RDW temporal change between the two groups. In the correlation analysis, no significant correlation was found between NLR, PLR, and their temporal changes, ipsilateral and contralateral stenosis rates, age, and residual stenosis rates.
Conclusion: There was no significant relationship between the development of newly developing ischemic lesions and NLR and PLR values and the associated temporal changes.

Published: June 2023

Background: The common reference intervals (RIs) for thyroid hormones currently used in China are provided by equipment manufacturers. This study aimed to establish thyroid hormone RIs in the population of Lanzhou, a city in the subplateau region of northwest China, and compare them with previous reports and manufacturer-provided values.Methods: In total, 3,123 individuals (1,680 men, 1,443 women) from Lanzhou, an iodine-adequate area of China, perceived as healthy were selected. The Abbott Architect analyzer was used to determine the serum concentration of thyroid hormones. The 95% RI was estimated using the 2.5th and 97.5th percentiles as the lower and upper reference limits, respectively.Results: The serum levels of thyroid-stimulating hormone (TSH), total triiodothyronine (TT3), antithyroglobulin (ATG) antibody, and antithyroid peroxidase (ATPO) antibody levels were significantly correlated with sex (P<0.05). TSH, total thyroxine (TT4), and ATPO levels were significantly correlated with age (P<0.05). The serum levels of TSH, ATG, and ATPO in men were significantly lower than in women; in contrast, the serum TT3 level was significantly higher in men than in women (P<0.05). Serum TSH, TT3, TT4, and ATG levels differed across age groups (P<0.05), but no such variation was observed for ATG levels (P>0.05). The established RIs of TSH, ATG, and ATPO in this study differed between sexes (P<0.05). The thyroid hormone RIs established herein were inconsistent with the manufacturer-provided values.Conclusion: The RIs of thyroid hormones in the healthy population of Lanzhou were inconsistent with those in the manufacturer’s manual. Validated sex-specific values are required for diagnosing thyroid diseases.

Son muchos los desafíos que enfrenta hoy la catequesis en la Iglesia y en el mundo actual. El contexto cultural, con el fenómeno de la comunicación digital, evidencia un cambio radical en la existencia y en las relaciones de las personas. El cambio de época que vivimos como humanidad y como planeta se caracteriza por una crisis global que se manifiesta en muchas dimensiones vitales que afectan directamente la práctica catequética de la Iglesia.
Las diversas características tanto del perfil del catequista como de la práctica catequética reconocidas por el Magisterio de la Iglesia deberían responder a las exigencias siempre nuevas del evangelio y a la coyuntura histórica actual. Dicha coyuntura es la que condiciona los distintos desafíos de la catequesis de cada época. ¿Cuáles son esos desafíos que se plantean hoy a la catequesis de cara a la evangelización del mundo del siglo XXI?
El presente ensayo busca poner de relieve cuatro desafíos imprescindibles que se plantean en hoy a la catequesis: el testimonial, el del encuentro con Jesús vivo en la comunidad, el de la actualización del lenguaje y el ecológico y medioambiental. Cada uno de estos desafíos puede llegar a ser una respuesta a la crisis global que sufrimos como humanidad.
Solitons in the Gauged Skyrme-Maxwell Model
Authors:   JINR, Russia, Livramento Leandro Roza , Radu Eugen ,   University of Aveiro, Portugal, Shnir Yakov ,   JINR, Russia
Published: June 2023

We consider soliton solutions of the U(1) gauged Skyrme model with the pion mass term. The domain of existence of gauged Skyrmions is restricted from above by the value of the pion mass. Concentrating on the solutions of topological degree one, we find that coupling to the electromagnetic field breaks the symmetry of the configurations, the Skyrmions carrying both an electric charge and a magnetic flux, with an induced dipole magnetic moment. The Skyrmions also possess an angular momentum, which is quantized in the units of the electric charge. The mass of the gauged Skyrmions monotonically decreases with increase of the gauge coupling.
Species delimitation, biogeography, and natural history of dwarf funnel web spiders (Mygalomorphae, Hexurellidae, Hexurella) from the United States / Mexico borderlands
Authors: Monjaraz-Ruedas Rodrigo , Mendez Raymond Wyatt , Hedin Marshal
Published: June 2023

The rarely encountered spider genus Hexurella Gertsch & Platnick, 1979 includes some of the smallest mygalomorph spiders in the world, with four poorly known taxa from central and southeastern montane Arizona, southern California, and northern Baja California Norte. At time of description the genus was known from fewer than 20 individuals, with sparse natural history information suggesting a vagrant, web-building, litter-dwelling natural history. Here the first published taxonomic and natural history information for this taxon is provided in more than 50 years, working from extensive new geographic sampling, consideration of male and female morphology, and sequence capture-based nuclear phylogenomics and mitogenomics. Several new species are easily diagnosed based on distinctive male morphologies, while a complex of populations from central and northern Arizona required an integrative combination of genomic algorithmic species delimitation analyses and morphological study. Four new species are described, including H. ephedrasp. nov., H. uwiiltilsp. nov., H. xericasp. nov., and H. zassp. nov. Females of H. encina Gertsch & Platnick, 1979 are also described for the first time. It is predicted that additional new species will ultimately be found in the mountains of central and northwestern Arizona, northern mainland Mexico, and the Mojave Desert of California.

Published: June 2023

Trauma disproportionately impacts people with HIV. To mitigate these adverse impacts, primary care providers can identify and address trauma with clients using a trauma informed care (TIC) approach. In 2018, CAI, an organization that provides national level training and capacity-building developed a TIC implementation model, now delivered in HIV and primary care agencies throughout the United States to integrate TIC into their culture, environment, and service delivery. New Jersey Trauma Informed Care (NJTIC) is the organization’s longest standing TIC initiative. To respond to the complex challenges of the COVID-19 pandemic, we developed a webinar series, Take 5, to leverage and expand upon the existing knowledge and skills of providers across 15 agencies part of the NJTIC project. This article describes the series’ purpose, to support staff and sustain and develop their TIC competencies during this unprecedented reality. Results of our evaluation indicated the reaction, satisfaction, and impact described by staff, who enhanced their TIC knowledge and utilized new skills with clients and themselves. Staff and their supervisors reported that the series offered consistency and support during an uncertain time. These promising practices can be applied broadly during crises to bolster knowledge, skills, collaboration, and self-care.

Authors: Badawy Abd El-Mohsen , Helmy Alaa
Published: June 2023

In this paper, we continue to introduce new properties of principal $ MS $-algebras deal with congruence relations via $ MS $-congruence pairs. Necessary and sufficient conditions for a pair of congruences $ (\theta_{1}, \theta_{2})\in Con(L^{\circ\circ})\times Con_{lat}(D(L)) $ to become an $ MS $-congruence pair of a principal $ MS $-algebra (principal Stone algebra) $ L $ are obtained. We describe the lattice of all $ MS $-congruence pairs of a principal $ MS $-algebra $ L $ which induced by the Boolean elements of $ L $. We introduce certain special congruence $ \Psi $ on a principal $ MS $-algebra and its related properties which are useful for the topic of this paper. A characterization of $ 2 $-permutable congruences using $ MS $-congruence pairs of principal $ MS $-algebras is established. Finally, a characterization of $ n $-permutability of congruences of principal $ MS $-algebras is given, which is a generalization of the characterization of $ 2 $-permutability of congruences of such algebras.
QL-ADIFA: Hybrid optimization using Q-learning and an adaptive logarithmic spiral-levy firefly algorithm
Authors: Tan Shuang , Zhao Shangrui , Wu Jinran
Published: June 2023

Optimization problems are ubiquitous in engineering and scientific research, with a large number of such problems requiring resolution. Meta-heuristics offer a promising approach to solving optimization problems. The firefly algorithm (FA) is a swarm intelligence meta-heuristic that emulates the flickering patterns and behaviour of fireflies. Although FA has been significantly enhanced to improve its performance, it still exhibits certain deficiencies. To overcome these limitations, this study presents the Q-learning based on the adaptive logarithmic spiral-Levy flight firefly algorithm (QL-ADIFA). The Q-learning technique empowers the improved firefly algorithm to leverage the firefly's environmental awareness and memory while in flight, allowing further refinement of the enhanced firefly. Numerical experiments demonstrate that QL-ADIFA outperforms existing methods on 15 benchmark optimization functions and twelve engineering problems: cantilever arm design, pressure vessel design, three-bar truss design problem, and 9 constrained optimization problems in CEC2020.
Attention distraction with gradient sharpening for multi-task adversarial attack
Authors: Liu Bingyu , Hu Jiani , Deng Weihong
Published: June 2023

The advancement of deep learning has resulted in significant improvements on various visual tasks. However, deep neural networks (DNNs) have been found to be vulnerable to well-designed adversarial examples, which can easily deceive DNNs by adding visually imperceptible perturbations to original clean data. Prior research on adversarial attack methods mainly focused on single-task settings, i.e., generating adversarial examples to fool networks with a specific task. However, real-world artificial intelligence systems often require solving multiple tasks simultaneously. In such multi-task situations, the single-task adversarial attacks will have poor attack performance on the unrelated tasks. To address this issue, the generation of multi-task adversarial examples should leverage the generalization knowledge among multiple tasks and reduce the impact of task-specific information during the generation process. In this study, we propose a multi-task adversarial attack method to generate adversarial examples from a multi-task learning network by applying attention distraction with gradient sharpening. Specifically, we first attack the attention heat maps, which contain more generalization information than feature representations, by distracting the attention on the attack regions. Additionally, we use gradient-based adversarial example-generating schemes and propose to sharpen the gradients so that the gradients with multi-task information rather than only task-specific information can make a greater impact. Experimental results on the NYUD-V2 and PASCAL datasets demonstrate that the proposed method can improve the generalization ability of adversarial examples among multiple tasks and achieve better attack performance.
The role of the input frequency in L1 Spanish phonological acquisition. A corpus-based study
Authors: Garrote Salazar Marta
Published: June 2023

This study presents the phonological system exhibited by children (n=59) aged 3;0 to 6;0 and focuses on the role of input frequency. Using a spontaneous child speech corpus of Spanish (CHIEDE) as a data source, as well as computational processing techniques -including an automatic phonological transcriber-, data relating to the phonological level was retrieved. This resulted in a phonological inventory of Spanish-speaking children, ordered by frequency of use, which may serve as a model for research on typical and atypical child language development. Additionally, a study was carried out on the stability of the participants’ phonological systems by calculating the variability that the different age groups displayed, and outcomes were compared with other similar corpora. Results obtained from the comparison of the phonological inventory of children and adults show that there is a relationship between frequency of use in adult speech and the order of acquisition of phonemes.

Published: June 2023

The upsurge of the COVID-19 pandemic has drastically changed the delivery of library services. With the physical closure of library doors, libraries were forced to provide expanded and strengthened access to library collections. This study aims to document the curbside book delivery service of Nazarbayev University Library during the pandemic specifically from Fall 2020 to Fall 2021. The study revealed that the patrons found the delivery service effective, especially during the pandemic. Despite the challenge of having a limited number of staff to work, the library personnel found themselves untiringly serving the patrons and were considered as front liners who provide the service despite the harm of getting infected with the virus. Although no one would hope to have another crisis, the library has proven itself as flexible as it can be and can go the extra mile in response to the changing needs of the time.

This paper presents the flight-testing method for system identification used during the LUA autonomous helicopter development and the computed on-axis dynamic model derived from the flight test data. The applied flight-testing method achieved excellent results with very low cross-control correlation, which was verified by comparing the SISO and MISO frequency response. A simple, yet accurate, on-axis dynamic model was derived for the hover condition using the higher-order hybrid model formulation, demonstrating that the vehicle response is dominated by the coupled rotor/fuselage dynamics. A short analysis of the LUA and similar size helicopters dynamic modes is completed, finding that their responses are dominated by the rotor dynamics, which might be a common trait among small-scale helicopters due to design choices in low-weight aircraft.

Published: June 2023

This paper describes the aerodynamic and flight dynamic modeling of a biplane tailsitter Unmanned Aerial Vehicle (UAV) that is capable of vertical takeoff and landing (VTOL) and high efficiency cruise flight. The conventional quasi-steady aerodynamic model is enhanced incrementally while discussing the limitations of the models. The effect of model refinement on the forward transition trajectory is studied as it involves most of unsteady effects due to the aggressive nature of forward transition maneuver in which the UAV pitches by 90 degrees. An octarotor biplane tailsitter vehicle is fabricated and instrumented to collect flight test parameters for the transition flight. The states of the UAV during the transition flight are recorded onboard using the autopilot and are subsequently used to validate the simulation. The use of unsteady aerodynamic model helps improve the predicted flight trajectory.

Although SGLT2 inhibitors have been initially employed in the treatment of type 2 diabetes, their clinical use was later extended to the treatment of other conditions such as heart failure, chronic kidney disease and obesity. In patients with type 2 diabetes, the administration of SGLT2 inhibitors has been associated with an increased incidence of urogenital infections, which may be linked to high glucose levels in the urine. The rate of urogenital side effects may be different in non-diabetic patients. The aim of this study was to review the risk of urogenital infections in non-diabetic patients taking SGLT2 inhibitors. Materials and methods: We conducted a systematic review and meta-analysis by searching PubMed and EMBASE for randomized controlled trials (RCTs) reporting urogenital adverse effects in non-diabetic patients treated with SGLT2 inhibitors. Odds ratios for urogenital infections were calculated using random effect Mantel-Haenszel statistics. Results: Out of 387 citations retrieved, 12 eligible RCTs were assessed for risk of bias and included in the meta-analysis. Compared to placebo, SGLT2 inhibitors were associated with increased odds of genital infections (OR 3.01, 95% CI: 1.93- 4.68, 9 series, 7326 participants, Z = 5.74, p < 0.0001, I2 = 0%) as well as urinary tract infections (OR 1.33, 95% CI: 1.13-1.57, 9 series, 7326 participants, Z = 4.05, p < 0.0001, I2 = 0%). When four trials investigating the effects of SGLT2 inhibitors in populations including both diabetic and non-diabetic patients were considered, administration of SGLT2 inhibitors in diabetic patients was associated with significantly higher odds of genital infections but not urinary tract infections compared to patients without type 2 diabetes. In patients taking placebo, the odds for urinary tract infections were significantly increased in diabetic patients compared to non-diabetic patients. Conclusions: The risk of genital infections is increased also in non-diabetic patients taking SGLT2 inhibitors although at a lesser extent that in diabetics. A careful assessment of the local anatomical conditions and of the history of previous urogenital infections is desirable to select those patients who need more intense follow-up, possibly combined with prophylactic measures of infections during treatment with SGLT2 inhibitors.
Clinician's perspective on the diagnosis of primary cutaneous B-cell lymphoma

Primary cutaneous B-cell lymphomas (PCBCLs) account for 25% of all cutaneous lymphomas: the main subtypes within this group are primary cutaneous follicle center lymphoma (PCFCL), primary cutaneous marginal zone B-cell lymphoma (PCMZL), and primary cutaneous diffuse large B-cell lymphoma, leg type (PCDLBCL, LT). Biopsy with histological examination and immunohistochemistry is the gold standard for the diagnosis of PCBCLs. A clinically oriented approach to PCBCLs classifies these entities according to their clinical behavior into indolent or intermediate to aggressive subtypes. While PCFCL and PCMZL are indolent diseases, PCDLBCL, LT has an aggressive course spreading to extracutaneous sites in approximately 45% of cases. Therefore, instrumental staging for extracutaneous disease is not performed following a diagnosis of PCMZL and PCFCL, while it is recommended for PCDLBCL, LT. Finally, dermatoscopy, under the guide of a strong clinical suspicion, may provide a novel diagnostic tool to enhance the clinical recognition of different subtypes of PCBCL.

Copper-doped hematite thin films were prepared by spray pyrolysis technique using a mixture of ethanol and distilled water precursors. Visual observations showed that aqua precursor produced films of less integrity compared with ethanol that produced thin, uniform and transparent yellowish-brown films that adhered well to the substrate. Composition and thickness measurements determined by RBS revealed that ethanol precursor produced thinner films of 94.45 and 51.77 nm while aqua precursor produced films of 1,370 and 1,120 nm for undoped and Cu-doped Fe2O3 respectively. This is an indication that ethanol solutions produced nano-thick films of high integrity. The composition revealed that only the Cu-doped Fe2O3 deposited by ethanol solution gave composition close to stoichiometric Fe2O3 while the others gave non-stoichiometric Fe(OH)3 . Optical characterization carried out using UV-visible spectrophotometer in transmittance mode indicated that the film thickness was directly proportional to the number of passes which is inversely proportional to the transmittance. Three bandgap determination methods namely; Tauc, Absorption Fitting Spectrum (AFS) and Davis-Mott were employed with the result that Tauc and AFS gave close direct and indirect bandgap energies (Eg) of 3.44 and 1.98 for AFS and 3.43 and 2.32 eV for Tauc respectively. The Urbach tail energy determined was 1,100 meV which is an indication of a broad onset of absorption. The steepness parameter (?) was found to be 7.83 while the electron-phonon (Eph ) coupling energy was found to be 0.85 eV. It was also observed that the refractive index (n) was about 15 times greater than the extinction coefficient (k). In the study of the dispersion parameters using single oscillator and Sellmier models, the values of the single oscillator energy (Eosc ), dispersion energy (Ed), zero frequency dielectric constant, zero frequency refractive index, the average oscillator strength (So), the average oscillator parameter and the dispersion parameters were determined. All the values of the parameters estimated are of the same order of magnitude with other semiconducting materials. The study showed that Cu-doped Fe2O3 could be employed as dielectric material as well as in optoelectronic devices.
Historical charcoal-burning mounds in the Engure area, Latvia, and their significance for the history of forest exploitation

The application of airborne laser scanning (LiDAR) has led to the discovery of numerous man-made mounds encircled by pits in the forests near Engure, north-western Latvia. Field survey revealed these to be historical features remaining from charcoal-burning in mound kilns. Archaeological excavation was undertaken at one of the features, along with analysis of recovered wood charcoal, dendrochronological and radiocarbon (14C) dating and archival research into documents relating to historical charcoal production in the area. All of the analysed charcoal samples are from Scots pine (Pinus sylvestris L.), the dominant tree species in this area.
It is concluded that the large-scale charcoal production served the needs of the ironworks operating at Engure in the 17th–18th century. The study of the charcoal-burning mounds has permitted estimation of the source area and volume of the wood supplied for charcoal production, and the period during which it was undertaken. Wood harvesting on such a scale had a significant impact on the surrounding forests and also had some effect on subsequent forest growth in the area. These findings demonstrate that features of this kind deserve to be regarded as archaeological remains of considerable research potential.
