Run-Time Adaptive In-Kernel BPF/XDP Solution for 5G UPF

Flexibility is considered a key feature of 5G softwarization to deliver a timely response to changes in network requirements that may be caused by traffic variation, user mobility, dynamic network function chains, slice lifecycle management operations, among others. In this article, we evolve the upf-bpf1 open-source project by proposing a new design to improve its flexibility by reducing the run-time adaptation time. The project proposes an in-kernel solution based on BPF and eXpress Data Path (XDP) for 5G User Plane Function (UPF) implementations. The Just-In-Time (JIT) compilation may have a huge impact on the adaptation time due to the in-kernel verification of the BPF programs at run-time. Our results show latency improvements of around 95% to inject the BPF program into the Linux kernel. Furthermore, the solution keeps the same functionalities and delivers a packet processing performance of around 10–11 Mpps using 6 cores with almost 70% of the CPU utilization in downlink/uplink directions.
Microwave Absorbing Material of Ba0.95La0.05Fe12-2xZnxTixO19 (x = 0; 0.5; and 1.0) with Broadband Characteristic at X-band Frequency

In this study, hexaferrite Ba0.95La0. 05Fe12-2xZnxTixO19 (x = 0; 0.5; and 1.0) was synthesized and characterized, which can be applied as microwave absorber in the X-band frequency range. It is a potential candidate for a radar absorbing material for microwave absorption, particularly for use in anti-radar paint in the defense sector. Samples were prepared using solid state reaction synthesis with high energy milling. After sintering at the right temperature, the samples were characterized using an X-ray diffractometer (XRD), a scanning electron microscope (SEM), a vibrating-sample magnetometer (VSM) and vector network analysis (VNA). The XRD characterization results indicated that all samples were in phase and had a hexagonal lattice structure with a P63/mmc space group and a crystallite size between 38 and 45 nm. The surface morphology of the characterization results using SEM showed a heterogeneous particle shape with particle sizes ranging from 140 to 200 nm. Substitution of Ti4+ ions for Fe3+ ions by Zn2+ ions resulted in a decrease of the magnetic saturation (Ms), the magnetic remanence, and the sample’s coercivity field. With a sample thickness of 1.5 mm, the VNA results confirmed that the ability to absorb microwaves and bandwidth will increase along with increase of the substitution value x. The reflection loss value was about -13.3 dB at a frequency of around 11 GHz, with a bandwidth of 1.4 GHz for the sample with x = 1.0 composition.
A Study Protocol to Assess the Effects of Storage on Blood Components and Packed Red Blood Cells in Blood Bank

Background: For preservation of Packed Red blood cells (PRBCs), the recommended optimum conditions includes storage at 2-60 C in specialised blood storage refrigerators. PRBCs are required for blood transfusions in some life-saving situations and can be stored for 42 days. But during this storage period, continuous degradation of RBCs occurs and oxygen carrying capacity gets reduced. These changes inadvertently affect the lifespan of stored RBCs. Therefore during this storage period, routine evaluation is recommended. This study aimed to assess the storage effects on Blood Component and internal quality control of packed red cells. Methodology: This Prospective Cohort study includes analysis of 50 Packed Red blood cells bags for RBC count, Haemoglobin and RBC indices. The analysis will be done on Day 1, Day 21 and Day 42 from the date of blood collection. The study will be carried in Jawaharlal Nehru Medical College Blood Centre and Department of Pathology, JNMC, AVBRH, Sawangi Meghe, Wardha. The data collected will be analysed using appropriate statistical tools. Expected Results: Haemoglobin and Red cell indices with the help of cell counter will be analysed. Effects of storage on packed red blood cells will be drawn from the analysis.
Anaplastic Large Cell Lymphoma: Molecular Pathogenesis and Treatment

Simple Summary Anaplastic large cell lymphoma is a rare type of disease that occurs throughout the world and has four subtypes. A summary and comparison of these subtypes can assist with advancing our knowledge of the mechanism and treatment of ALCL, which is helpful in making progress in this field. Abstract Anaplastic large cell lymphoma (ALCL) is an uncommon type of non-Hodgkin’s lymphoma (NHL), as well as one of the subtypes of T cell lymphoma, accounting for 1 to 3% of non-Hodgkin’s lymphomas and around 15% of T cell lymphomas. In 2016, the World Health Organization (WHO) classified anaplastic large cell lymphoma into four categories: ALK-positive ALCL (ALK+ALCL), ALK-negative ALCL (ALK−ALCL), primary cutaneous ALCL (pcALCL), and breast-implant-associated ALCL (BIA-ALCL), respectively. Clinical symptoms, gene changes, prognoses, and therapy differ among the four types. Large lymphoid cells with copious cytoplasm and pleomorphic characteristics with horseshoe-shaped or reniform nuclei, for example, are found in both ALK+ and ALK−ALCL. However, their epidemiology and pathogenetic origins are distinct. BIA-ALCL is currently recognized as a new provisional entity, which is a noninvasive disease with favorable results. In this review, we focus on molecular pathogenesis and management of anaplastic large cell lymphoma.
Near-Optimal BEM OTFS Receiver With Low Pilot Overhead for High-Mobility Communications

In this paper, a new receiver design based on basis expansion model (BEM) orthogonal time frequency space (OTFS) is presented for high-mobility communications with Doppler-spread channel. By deriving an analytical BEM OTFS system model, a low-order generalized complex exponential BEM (GCE-BEM) aided rough channel estimation is proposed at the initial stage with low pilot overhead, followed by equalization. Then, the refinement of channel estimation and equalization is conducted iteratively, in which a high-resolution GCE-BEM model with a large BEM order is adopted and the detected data symbols are exploited as pseudo-pilots, leading to higher estimation accuracy. Simulation results show that the proposed BEM OTFS receiver significantly outperforms the existing OTFS receivers in terms of the mean square error (MSE) of channel estimation and bit error rate (BER), while featuring low pilot overhead. Results also show the near-optimal performance of the novel solution, i.e., achieved BER is very close to the case of perfect channel estimation. The theoretical lower bound on MSE of channel estimation is derived to verify the effectiveness of the proposed BEM OTFS receiver, which is shown to be close to simulation results.
Effect of Quinoline on the Phospholipid Profile of Curvularia lunata and Its Microbial Detoxification

Quinoline is an N-heterocyclic compound commonly found in wastewater, especially that derived from coal processing, chemical, and pharmaceutical industries. In the present study, the microscopic fungus Curvularia lunata IM 4417, which is known to degrade various xenobiotics, was used. The aim of the research was to study the elimination of quinoline and its influence on fungal phospholipids, which are considered to be excellent indicators of environmental monitoring. Quinoline biodegradation products and phospholipid contents were analyzed using gas chromatography–mass spectrometry and liquid chromatography–tandem mass spectrometry. C. lunata IM 4417 degraded quinoline, which led to the formation of conjugates of glucose with hydroxylated derivatives of the compound. Toxicity tests (Artoxkit M and Microtox assay) indicated that the elimination of lower concentrations of quinoline was efficient and led to a reduction in sample toxicity. The presence of quinoline also significantly affected the profile of fatty acids and phospholipids. The addition of quinoline to a culture of C. lunata IM 4417 caused an increase in the content of phosphatidylcholine (PC) and a decrease in the amount of phosphatidylethanolamine (PE), two major structural lipids. Additionally, decreases in the contents of phosphatidylinositol (PI) and phosphatidylserine (PS), which are responsible for tolerance to toxic substances, cell viability, and signal transduction, were noted. Thus, it can be concluded that the presence of quinoline modifies the membrane composition, and this change may be an important indicator of the presence of N-heterocyclic compounds or other toxins in the environment.
Condylar Height: Age and Sex Determination Using Orthopantogram in Forensics

Background: Since time immemorial, Condyles has been the area of interest for anthropologists, and the condyle size in men is higher than that of women. The condyle measurement is usually studied in two planes, i.e. anteroposterior and mediolateral, which are more gender-alliant. Different conventional X-rays are used for condylar imaging whose panoramic views of both condyles are provided by the OPG. For the creation of biological profiles during mass disasters the skull has remained useful. However, the technical procedures must in most cases be based on fragmented skull bones, when the whole skull is not available. Materials and Methods: The study samples were retrieved from DIAS of Saveetha Dental College and Hospitals between the retrospective months from November 2020 to February 2021. The study sample consisted of 300 OPG’s (150 males and 150 females), which were taken using Genoray Papaya machine, of age ranging from 10 to 24.9 years in which mandibular condylar height was measured using PlanmecaRomexis Software. Results: The standard deviation for evaluation of condylar height for female is ±4.38 while for males it is ±4.91. The standard error mean for condylar height for females is 0.35808 and for males is 0.40136 with non-significant p value of 0.893. Conclusion: By analysing the condylar mandibular height, the results of this study could improve human identification.For validation and comparison purposes, further research may be required in order to expand other associated parameters into a broader sample size.
A Re-examination of Birth Control in the First Half of Twentieth Century Japan: Yoshioka Yayoi’s Anti-birth Control Position

ABSTRACT The birth control movement in Japan first arose in the early 1920s. The Japanese government disapproved of birth control because it was enthusiastic about population growth to strengthen national power. Simultaneously, the movement was accompanied by a clash of ideologies among its supporters and critics in society. Existing research is especially interested in state policies and management, as well as the viewpoints and activities of birth control activists. This paper delves into a less-discussed topic: the perspectives of birth control opponents, focusing on Yoshioka Yayoi (1871–1959), a gynaecologist, educator, and women’s rights activist. It argues that during the early twentieth century, state policies did not always play a decisive role in shaping people’s anti-birth control attitudes. Yoshioka’s opposing views in interwar Japan incorporated her concerns for women’s morals and health, which were heavily influenced by social values and contraceptive technology at the time. As World War II began, her anti-birth control views had a strong political implication – promoting childbirth as a war effort. Despite Yoshioka’s alignment with the state, the distinctions that existed between her views and national ideologies should not be overlooked. Yoshioka’s ideas are conservative and show limitations. However, through her case, this article hopes to offer insight into the different meanings of birth control for people living in the early twentieth century, not only in Japan but also in a global context. Many people were reluctant to embrace this new family planning method due to moral reasons and uncertainty. Keeping birth control out of people’s daily lives, especially for conservatives like Yoshioka, was an optimal way to benefit individuals.
Systems Design and Performance of Hot and Cold Supersonic Microjets

We discuss approaches to the design and fabrication of supersonic micropropulsion systems. The core of the system is a de Laval nozzle which accelerates the fluid from a plenum, through a 30 micron throat. The flow is expanded downstream to supersonic speeds in excess of Mach 4. Using the nozzle as a simple cold-gas thruster, good Isp efficiencies are demonstrated, although side-wall boundary layer contamination and the limitations of MEMS fabrication technologies are apparent. The system performance is greatly improved by heating the flow in the plenum (i.e. a resistojet). This is achieved using integrated microheaters, designed to optimally heat the fluid with a minimum of pressure loss in the plenum. The heaters are fabricated in a novel manner, using silicon both as the structural material and the electrical heater element. The performance of the resistojet system is tested and compares favorably with the cold-gas efficiencies at similar Reynolds numbers.

Objective: To assess TOM functioning and identify its correlates among a sample of patients with acute psychosis, schizophrenia and healthy controls. Methods: Case control study conducted on 20 patients with acute psychosis, 40 patients with schizophrenia and 60 healthy control volunteers. Patients admitted at Okasha Institute of Psychiatry, Ain Shams University Hospitals, diagnosed using the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I). Severity of symptoms assessed by the Scale for the Assessment of Positive Symptoms and the Scale for the Assessment of Negative Symptoms, while volunteers were assessed by General health questionnaire. All groups were assessed by Reading the mind in the eyes test (RMET). Results: There was significant difference between patients with schizophrenia who scored worse at the RMET than patients with acute psychosis while both have TOM deficit in comparison with the control group. No significant correlation between age or gender in all the three groups and their TOM functioning. There was significant negative correlation between duration of illness of patients with schizophrenia and their TOM functioning. In patients with acute psychosis group, negative symptoms were negatively correlated with the TOM functioning, while in patients with schizophrenia group positive and negative symptoms were negatively correlated with their TOM functioning.
Correlates Of Academic Anxiety Among Adolescents

Adolescence is the period that is characterized by stress and storm as defined by Stanley Hall. During this period, academic functions become the major source of anxiety in adolescents. Academic anxiety is uncomfortable / uneasiness feeling of students in academic institution towards academic tasks like exam preparation, presentations, assignments, interviews, curriculums, teaching methodologies, relationship with peers etc. From the literature review findings demonstrated that external factors like home and school environment and internal factors as academic achievement, academic motivation and study habits provoked as the key correlates of academic anxiety among adolescents
Revisiting the Resazurin-Based Sensing of Cellular Viability: Widening the Application Horizon

Since 1991, the NAD(P)H-aided conversion of resazurin to fluorescent resorufin has been widely used to measure viability based on the metabolic activity in mammalian cell culture and primary cells. However, different research groups have used divergent assay protocols, scarcely reporting the systematic optimization of the assay. Here, we perform extensive studies to fine-tune the experimental protocols utilizing resazurin-based viability sensing. Specifically, we focus on (A) optimization of the assay dynamic range in individual cell lines for the correct measurement of cytostatic and cytotoxic properties of the compounds; (B) dependence of the dynamic range on the physical quantity detected (fluorescence intensity versus change of absorbance spectrum); (C) calibration of the assay for the correct interpretation of data measured in hypoxic conditions; and (D) possibilities for combining the resazurin assay with other methods including measurement of necrosis and apoptosis. We also demonstrate the enhanced precision and flexibility of the resazurin-based assay regarding the readout format and kinetic measurement mode as compared to the widely used analogous assay which utilizes tetrazolium dye MTT. The discussed assay optimization guidelines provide useful instructions for the beginners in the field and for the experienced scientists exploring new ways for measurement of cellular viability using resazurin.
ON MULTIPLE STRUCTURAL BREAKS IN DISTRIBUTION: AN EMPIRICAL CHARACTERISTIC FUNCTION APPROACH

We estimate and test for multiple structural breaks in distribution via an empirical characteristic function approach. By minimizing the sum of squared generalized residuals, we can consistently estimate the break fractions. We propose a sup-F type test for structural breaks in distribution as well as an information criterion and a sequential testing procedure to determine the number of breaks. We further construct a class of derivative tests to gauge possible sources of structural breaks, which is asymptotically more powerful than the smoothed nonparametric tests for structural breaks. Simulation studies show that our method performs well in determining the appropriate number of breaks and estimating the unknown breaks. Furthermore, the proposed tests have reasonable size and excellent power in finite samples. In an application to exchange rate returns, our tests are able to detect structural breaks in distribution and locate the break dates. Our tests also indicate that the documented breaks appear to occur in variance and higher-order moments, but not so often in mean.
A New Abnormality Detection Approach for T1-Weighted Magnetic Resonance Imaging Brain Slices Using Three Planes

Generally, radiologists analyse the Magnetic Resonance Imaging (MRI) by visual inspection to detect and identify the presence of tumour or abnormal tissue in brain MR images. The huge number of such MR images makes this visual interpretation process, not only laborious and expensive but often erroneous. Furthermore, the human eye and brain sensitivity to elucidate such images gets reduced with the increase of number of cases, especially when only some slices contain information of the affected area. Therefore, an automated system for the analysis and classification of MR images is mandatory. In this paper, we propose a new method for abnormality detection from T1-Weighted MRI of human head scans using three planes, including axial plane, coronal plane, and sagittal plane. Three different thresholds, which are based on texture features: mean, energy and entropy, are obtained automatically. This allowed to accurately separating the MRI slice into normal and abnormal one. However, the abnormality detection contained some normal blocks assigned wrongly as abnormal and vice versa. This problem is surmounted by applying the fine-tuning mechanism. Finally, the MRI slice abnormality detection is achieved by selecting the abnormal slices along its tumour region (Region of Interest - ROI).
Sandwich Fluorescence Detection of Foodborne Pathogen Staphylococcus aureus with CD Fluorescence Signal Amplification in Food Samples

Timely detection of Staphylococcus aureus (S. aureus) is critical because it can multiply to disease−causing levels in a matter of hours. Herein, a simple and sensitive DNA tetrahedral (Td) fluorescence signal amplifier with blue carbon quantum dots (bCDs) was prepared for sandwich detection of S. aureus. bCD was modified at the apex of Td, and an aptamer on Td was used to accurately identify and “adsorb” the amplifier to the surface of S. aureus. Atomic force microscopy (AFM) demonstrates the successful preparation of this signal amplifier. The fluorescence intensity emitted in this strategy increased 4.72 times. The strategy showed a stronger fluorescence intensity change, sensitivity (linear range of 7.22 × 100–1.44 × 109 CFU/mL with a LOD of 4 CFU/mL), and selectivity. The recovery rate in qualified pasteurized milk and drinking water samples was 96.54% to 104.72%. Compared with simple aptamer sandwich detection, these fluorescence signal amplifiers have improved fluorescence detection of S. aureus. Additionally, this fluorescent signal amplification strategy may be applied to the detection of other food pathogens or environmental microorganisms in the future.
“Putting Down and Letting Go”: An Exploration of a Community-Based Trauma-Oriented Retreat Program for Military Personnel, Veterans, and RCMP

(1) Background: Current military members, veterans, and Royal Canadian Mounted Police (RCMP) experience higher rates of posttraumatic stress disorder (PTSD) and moral injury (MI). Trauma-oriented retreats have been offered as a means of addressing these concerns. This article aims to explore the impact of a non-evidence-based trauma-oriented retreat for the above populations experiencing PTSD or MI; (2) Methods: This qualitative study, nested within the larger mixed-methods pre/post longitudinal follow-up study, examined the experiences of 124 military members, veterans, and RCMP who participated in the retreat. Data were collected from semi-structured interviews and first-hand observations of the organization. Analysis was conducted using thematic analysis while being informed by realist evaluation principles; (3) Results: The results showed that important contextual elements were related to participants being ready, having multiple comorbidities and using the program as a first or last resort. Effectual mechanisms included a home-like setting; immersion; credibility of facilitators; experiential learning; an holistic approach; letting go, and reconnecting to self. Outcomes included: re-finding self, symptom management, social connection, and hope for a meaningful life. The gendered analysis suggested less favorable results; (4) Conclusions: Care is warranted as the evidence-base and effectiveness of trauma-oriented retreats yet needs to be established prior to broad use.
