Circularly Polarized Antenna With Specified AR and Gain Beamwidth for Spaceborne Applications

For spaceborne antennas, the gain and axial ratio (AR) within a specified beamwidth usually should be considered due to the coverage area requirement. As a result, this letter presents a circularly polarized antenna with the specified gain and AR beamwidth for spaceborne applications. The antenna with a totally circular structure is proposed to realize the specified gain and AR within the beamwidth of 130°. It is composed of one patch and two cavities. The working mechanism is presented. It can fully fulfill the requirements in the operational passband from 5.8 to 6.5 GHz. To verify the design, the antenna is fabricated and measured. The simulated results agree well with the measured ones. For the measurement results, within the beamwidth of 130°, the realized gain is larger than −0.7 dBic, and the spatial AR is better than 3.3 dB. The average boresight gain is 5.37 dBic. This indicates that the proposed antenna is a good candidate for spaceborne applications.
Effectiveness of Photobiomodulation With Low-Level Laser Therapy on the Implant Stability Quotient at Different Time Intervals: A Randomized Clinical Trial

Background Photobiomodulation techniques, particularly low-level laser therapy (LLLT), have gained traction due to their ability to accelerate osseointegration by stimulating cellular metabolism and promoting tissue healing. This study explores the effectiveness of LLLT around dental implants at various intervals after placement. Using resonance frequency analysis (RFA), the implant stability quotient (ISQ) was measured to assess implant stability. Methodology This split-mouth, randomized, single-blinded clinical trial included 20 participants undergoing dental implant placement. The test group received LLLT while the control group had no laser treatment. Implant stability was assessed using RFA at one, two, four, and twelve weeks post-implant placement. Statistical analysis involved descriptive statistics, repeated-measures analysis of variance (ANOVA), and t-tests. Results The repeated-measures ANOVA analysis showed significant differences in the ISQ values between the LLLT group and the control group at two weeks and three months post-implant placement. The LLLT group exhibited higher ISQ values, indicating greater implant stability and improved osseointegration compared to the control group. These findings suggest the potential benefits of LLLT in enhancing dental implant outcomes. Conclusions LLLT shows promise in improving dental implant outcomes, with enhanced stability and osseointegration. Further research is needed to validate these results and integrate LLLT into routine dental implant procedures.
Height Growth Rates of Canopy Tree Species in Southern Appalachian Gaps

Annual height growth rates for saplings (1-12 m high) of 13 canopy tree species were measured in natural gaps of southern Appalachian cove forests. Study sites were limited to three federally protected tracts of land at mid (570 m) to high (1300 m) elevations in which little or no man-made disturbance was evident. Disturbances within these regions generally were due to small, single-tree gaps averaging 155 m2 for the saplings studied. In such gaps, average height growth was found to be about 30 cm/yr with species averages ranging from 18 to 49 cm/yr. The most commonly sampled species increased in growth rate in the order, Fagus grandifolia, Acer saccharum, Tilia heterophylla, Liriodendron tulipifera, and Halesia carolina. Topographic factors (i.e., slope, elevation, and aspect) and gap size and age were analyzed using a stepwise multivariate regression procedure. In general, the most rapid growth occurred for taller saplings in large young gaps in protected hillsides at lower elevations.
Effect of two sintering protocols on translucency and flexural strength of different monolithic zirconia materials: An In vitro study

Background: Dental ceramics and zirconia are increasingly being used with outstanding outcomes for various restorations such as fixed dental prosthesis, resin bonded FDPs, and implant restorations. Zirconia is a polymorphic ceramic that can be found in three various crystalline forms depending on temperature: monoclinic, tetragonal, and cubic. The monoclinic phase is stable at room temperature; unfortunately, its mechanical and optical properties are insufficient for clinical application; nonetheless, the tetragonal and cubic phases can be rendered stable at room temperature by applying stabilizing oxides. The multi-layered technology has shown an improvement in color of zirconia to mimic the natural teeth without affecting its mechanical properties. Aim of the Study: The aim of this In vitro study is to evaluate the effect of two sintering protocols: Conventional firing cycle and Speed firing cycle on translucency and Flexural strength of the novel color gradient zirconia and compare it to different monolithic zirconia material. Materials and Methods: 54 discs were constructed to be divided into 3 different groups each group sub divided to speed cycle group and conventional cycle group for materials: IPS e.max® ZirCAD® Prime, Katana ultra-translucent zirconia and BruxZir anterior, To compensate for sintering shrinkage, the zirconia samples were milled with dimensions bigger than the required final dimension. The discs were then sintered in a sintering furnace group conventional sintering and group speed sintering for each material. Results: Translucency for conventional firing, there was a significant difference between different groups the highest value was found in Katana UTML, followed by Zircad prime, while the lowest value was found at BruxZir and for speed firing there was a significant difference between different groups. The highest value was found in Katana UTML, followed by Zircad prime, while the lowest value was found at BruxZir. Flexural strength for conventional firing, there was a significant difference between different groups. The highest value was found in Zircad prime, followed by BruxZir, while the lowest value was found at Katana UTML; and for speed firing, there was a significant difference between different groups. The highest value was found in Zircad prime, followed by BruxZir, while the lowest value was found at Katana UTML. Conclusion: For all tested zirconia, zirconia samples sintered with the conventional sintering cycle showed a significantly higher translucency value than those sintered with the speed cycle. Katana UTML zirconia showed the highest translucency values while BruxZir zirconia exhibited the lowest values in both firing methods.
Mapping the Anti-Cancer Activity of α-Connexin Carboxyl-Terminal (aCT1) Peptide in Resistant HER2+ Breast Cancer

Simple Summary Breast cancer is a leading cause of death for women worldwide. This study aims to examine the mechanisms for the anti-cancer effects of a therapeutic peptide agent targeted to connexin 43 (Cx43) called alpha-connexin carboxyl-terminal peptide (aCT1). Findings from this study confirm that aCT1 promotes gap junction intercellular communication and Cx43 protein stabilization and that the peptide binds to Zonal Occludens-1 (ZO-1), consistent with prior reports on the mechanism of action of this agent. New findings from this study identify novel aCT1-interacting proteins and the effect of aCT1 on breast cancer signaling. Abstract Connexin 43 (Cx43) is a protein encoded by the GJA1 gene and is a component of cell membrane structures called gap junctions, which facilitate intercellular communication. Prior evidence indicates that elevated GJA1 expression in the HER2-positive (HER2+) subtype of breast cancer is associated with poor prognosis. Prior evidence also suggests that HER2+ breast cancers that have become refractory to HER2-targeted agents have a loss of Cx43 gap junction intercellular communication (GJIC). In this study, a Cx43-targeted agent called alpha-connexin carboxyl-terminal peptide (aCT1) is examined to determine whether GJIC can be rescued in refractory HER2+ breast cancer cells. A proposed mechanism of action for aCT1 is binding to the tight junction protein Zonal Occludens-1 (ZO-1). However, the true scope of activity for aCT1 has not been explored. In this study, mass spectrometry proteomic analysis is used to determine the breadth of aCT1-interacting proteins. The NanoString nCounter Breast Cancer 360 panel is also used to examine the effect of aCT1 on cancer signaling in HER2+ breast cancer cells. Findings from this study show a dynamic range of binding partners for aCT1, many of which regulate gene expression and RNA biology. nCounter analysis shows that a number of pathways are significantly impacted by aCT1, including upregulation of apoptotic factors, leading to the prediction and demonstration that aCT1 can boost the cell death effects of cisplatin and lapatinib in HER2+ breast cancer cells that have become resistant to HER2-targeted agents.
Optimized Combination Strategies for Hybrid Work Models in SMEs in the Post-COVID-19 Pandemic

This paper explores optimized combination strategies for implementing effective hybrid work models in small and medium-sized enterprises (SMEs) in the post-COVID-19 pandemic landscape. As remote and on-site workflows become increasingly intertwined, SMEs face distinct challenges in strategically adopting these blended models catered to their unique organizational constraints. This research aims to address the lack of tailored guidelines for SMEs by consolidating insights across multiple disciplines including leadership, organizational behavior, and digital transformation theory. We employ a mixed-methods approach combining surveys, interviews, case studies and longitudinal tracking to examine diverse aspects of hybrid model efficacy in SMEs. Key results reveal that balance between flexibility and in-person collaboration is crucial, but optimum ratios vary across industries. Additionally, inclusion risks must be mitigated and policies personalized to meet generational preferences. Practical recommendations focused on change management and leadership upskilling can significantly enhance SME productivity. We conclude that purpose-driven hybridity centered on belonging and resilience holds strategic advantages for SMEs navigating workforce transformation. Further comparative research can reveal additional success factors for context-specific hybrid work models.

Acoustic Echo Cancellation Algorithm Based on Kalman Filtering of Skewed Observation Noise

Acoustic echo cancellation (AEC) is one of the key technologies in the field of speech enhancement. AEC based on Kalman filter (KF) not only ensures the effectiveness of the dual-talk scenario but also improves its ability to converge quickly. However, the performance of AEC is significantly compromised due to the influence of near-end speech and sudden noise, as the noise distributions does not completely adhere to the assumptions of the standard KF. In this article, a novel AEC algorithm based on KF of skewed observation noise is proposed to improve the effectiveness of the algorithm in complex signal channel scenarios. Based on the assumption that the state noise follows Gaussian distributions while the observed noise follows skewed Student’s ${t}$ distributions, the proposed algorithm is presented. The simulation and experimental results demonstrate the advantages of the proposed algorithm as compared with the existing state-of-the-art filters in terms of echo cancellation ability and convergence performance.
Social Exclusion and Social Anxiety Disorder: The Temporal Need-threat Model of Ostracism

Social exclusion, or ostracism, is being excluded or rejected by others. It is the common behaviour within social situations. Detecting social exclusion could be essential for the survival of human creatures, as social exclusion could threaten the basic needs of human creatures: self-esteem and feelings of belongingness. Williams temporal need threat model introduces how individuals react toward ostracism. Usually, individuals can recover from social exclusion quickly by behaving pro-socially to reconnect to others and fortify the basic need(s) threatened by social exclusion. However, for individuals with higher social anxiety or social anxiety disorder, the negative social belief about themselves (unpopular, shyness) within a social situation inhibits their recovery speed from exclusion and desire to reconnect to others. When social exclusion happens, individuals with higher social anxiety or social anxiety disorder become more vulnerable in social situations. Individuals lose their ability to get used to social situations when they suffer long-term social exclusion. Acceptance and Commitment Therapy is suggested to be a helpful therapy for individuals suffering from long-term social exclusion and social anxiety disorder.
Análisis de residuos sólidos de palma africana, como alternativa de aprovechamiento de energías renovables en el departamento del Cesar

La demanda actual energética y los costos en energía van incrementando; la contaminación da necesidad a la utilización de energías limpias que impacten en menor medida el medio ambiente. Colombia al encontrarse ubicado en zona rica con climas, biodiversidad y ecosistemas variados, cuenta con gran potencial de energías renovables del aire, agua, sol y biomasa de residuos sólidos como los de palma de africana; hoy en día el 70% de energía se produce de hidroeléctricas y solo el 2% del país genera energías renovables. A pesar que Colombia es un país con gran potencial de biomasa y residuos agroindustriales no se aprovecha su potencial como materia prima en procesos alternos de conversión de energía tales como los procesos termoquímicos. Así mismo el departamento de Cesar cuenta con un potencial de 1.935,51 (TJ/Año) y una generación de residuos anuales de 209.759,99 Ton de Biomasa residual, con un potencial energético de biomasa disponible para su aprovechamiento. De esta manera, es posible establecer por medio de los resultados de investigación el uso de estos residuos en aplicaciones térmicas que conlleven a la generación de energía limpias en la región y el país.
Approaching Multi-Lingual Emotion Recognition from Speech - On Language Dependency of Acoustic/Prosodic Features for Anger Detection

This paper reports on monoand cross-lingual performance of different acoustic and/or prosodic features. We analyze the way to define an optimal set of features when building a multilingual emotion classification system, i.e. a system that can handle more than a single input language. Due to our findings that cross-lingual emotion recognition suffers from low recognition rates we analyze our features on both an American English and a German database. Both databases contain speech of real-life users calling into interactive voice response (IVR) platforms. After calculating performance scores when cross-lingual decoding is involved, i.e. when an emotion classification system is confronted with a language it has not been trained on, we further report on different strategies to build a single feature space that is capable of dealing with both languages. We estimate the relative importance of different features for different languages by looking at their distribution, their classification scores and their rank in terms of information gain ratio. Finally, we construct a feature space on the joint data, replacing two formerly separated system by a single on. We obtain a bi-lingual emotion recognition system which performs as well as the monolingual systems on the test data.
KEGGSum: Summarizing Genomic Pathways

Over time, the renowned Kyoto Encyclopedia of Genes and Genomes (KEGG) has grown to become one of the most comprehensive online databases for biological procedures. The majority of the data are stored in the form of pathways, which are graphs that depict the relationships between the diverse items participating in biological procedures, such as genes and chemical compounds. However, the size, complexity, and diversity of these graphs make them difficult to explore and understand, as well as making it difficult to extract a clear conclusion regarding their most important components. In this regard, we present KEGGSum, a system enabling the efficient and effective summarization of KEGG pathways. KEGGSum receives a KEGG identifier (Kid) as an input, connects to the KEGG database, downloads a specialized form of the pathway, and determines the most important nodes in the graph. To identify the most important nodes in the KEGG graphs, we explore multiple centrality measures that have been proposed for generic graphs, showing their applicability to KEGG graphs as well. Then, we link the selected nodes in order to produce a summary graph out of the initial KEGG graph. Finally, our system visualizes the generated summary, enabling an understanding of the most important parts of the initial graph. We experimentally evaluate our system, and we show its advantages and benefits.
Expression of HLA Class 1 In Iraqi Bladder Cancer Patients

HLA types studied in sixty bladder cancer patients. A control sample of 80 apparently disease free individuals was included for comparisons, matched for ethinical background (Iraqi Arabs), sex and age. The study demonstrated significant deviations in four antigens, HLA -A2, -B5, -B51 and -Cw7, when comparisons was made between patients and controls. The frequency of antigen Cw7 was increased in the patients, while antigens A2, B5, and B51 showed decreased frequencies. Other associations were also observed when the tumour staging and grading were considered.
Influence of the Neutralization Degree on the Ice Nucleation Ability of Ammoniated Sulfate Particles

Previous laboratory measurements suggest that ammonium sulfate crystals (AS, (NH4)2SO4) are efficient ice‐nucleating particles under cirrus conditions. Sulfate particles not completely neutralized by ammonium are less well studied and include two other solids, ammonium bisulfate (AHS, NH4HSO4) and letovicite (LET, (NH4)3H(SO4)2). In this work, we have obtained the first comprehensive data set for the heterogeneous ice nucleation ability of crystallized particles in the AS–LET–AHS system as a function of their degree of neutralization at a temperature of about 220 K. Quantitative data on nucleation onsets, ice‐active fractions, and ice nucleation active surface site densities were derived from expansion cooling experiments in a large cloud chamber and measurements with two continuous flow diffusion chambers. We found a strong dependence of the efficiency and the mode of heterogenous ice nucleation on the degree of neutralization. Ice formation for AS, mixed AS/LET, and LET crystals occurred by the deposition nucleation or pore condensation and freezing mode. The lowest nucleation onset was observed for AS, where 0.1% of the particles became ice‐active at an ice saturation ratio of 1.25. This threshold gradually increased to 1.35 for LET, and abruptly further to 1.45 for mixed LET/AHS crystals, which partially deliquesced and induced ice formation via immersion freezing. Pure AHS crystals did not form due to the inhibition of efflorescence. Our data allow for a more sophisticated treatment of ice formation in the AS–LET–AHS system in future model simulations, which have so far only considered the available data for AS alone.
Importancia de la evaluación del espesor de grasa y de magro dorsal en cerdas hiperprolíficas

In recent years, sows have undergone a great genetic transformation (productive and morphological), which leads to higher nutritional requirements during their productive cycle. The main objective of this study was to improve the knowledge about body reserves (backfat thickness and loin depth) in a commercial farm with hiperprolific sows. On a total of 283 sows of different parities, backfat thickness and loin depth were recorded at the day of insemination, at days 40 and 110 of gestation, and at weaning. Thus, the effect of parity and the effect of lean-to-fat ratio (categorized into three groups according to their 25th and 75th percentiles: Low, Medium and High) on body reserves during the whole period were evaluated; as well as its potential impact on some reproductive parameters. Gilts showed a lower fat deposition than primiparous and multiparous sows, mainly in early gestation; in addition, they had a greater loss of the loin during the lactation and the whole productive period. Regarding to lean-to-fat ratio, gilts with higher vs. lower ratio showed greater losses of backfat and loin depth during lactation. Backfat gain during the productive cycle was lower in primiparous and multiparous sows with the highest ratio; while during mid and late gestation, the loss of loin depth was lower than sows with the lowest ratio. Moreover, the initial values of backfat and loin depth presented a high and moderate positive correlation with their own backfat and loin depth values (during the whole period); however, the cross-correlation between backfat and loin depth was lower or null, highlighting the importance of measuring both. From a reproductive point of view, primiparous and multiparous sows with the highest lean-to-fat ratio showed the highest culling rate. The results underline the need for specific feeding management according to parity (nuliparous vs. primiparous and multiparous). The study also suggests that periodic measurements of backfat and loin depth are a useful tool that allows nutri - tionists to evaluate the feeding plan applied to each farm. Thus, the establishment of recommendations for the lean-to-fat ratio, on the one hand, would provide a more objective unit of measurement on the nutritional status of sows; and, on the other hand, would allow adjusting an adequate nutrient intake at each stage of the productive cycle of hyperprolific lines.
Développement d'une méthode de prédiction de l'orientation et de l'insertion des protéines dans une membrane modèle

Integral membrane proteins play many important roles, and account for 20 to 30% of the open reading frames code for this class of proteins. Most of the membrane proteins found on the Protein Data Bank do not have a known membrane orientation and insertion, and such information is not available from the standard PDB format. The orientation, insertion and conformation that the membrane proteins have when interacting with a lipid bilayer are important for understanding their functions, but they are difficult characteristics to obtain experimentally. Computational methods can help reduce the cost and time allocated to determine the characteristics of a membrane protein. In this project, we propose a new computational method that predicts the orientation and the insertion of a protein in a lipid bilayer. The method is based on the potential mean force of the insertion of the amino acid side chain analogs in a dioleoylphosphatidylcholine lipid bilayer.
