Redefining Wireless Communication for 6G:Signal Processing Meets Deep Learning with Deep Unfolding
Authors: Jagannath Anu , Jagannath Jithin
Published: August 2021

The year 2019 witnessed the rollout of the 5G standard, which promises to offer significant data rate improvement over 4G. While 5G is still in its infancy, there has been an increased shift in the research community for communication technologies beyond 5G. The recent emergence of machine learning approaches for enhancing wireless communications and empowering them with much-desired intelligence holds immense potential for redefining wireless communication for 6G. The evolving communication systems will be bottlenecked in terms of latency, throughput, and reliability by the underlying signal processing at the physical layer. In this position paper, we motivate the need to redesign iterative signal processing algorithms by leveraging deep unfolding techniques to fulfill the physical layer requirements for 6G networks. To this end, we begin by presenting the service requirements and the key challenges posed by the envisioned 6G communication architecture. We outline the deficiencies of the traditional algorithmic principles and data-hungry deep learning (DL) approaches in the context of 6G networks. Specifically, deep unfolded signal processing is presented by sketching the interplay between domain knowledge and DL. The deep unfolded approaches reviewed in this article are positioned explicitly in the context of the requirements imposed by the next generation of cellular networks. Finally, this article motivates open research challenges to truly realize hardware-efficient edge intelligence for future 6G networks.
ABLATIVE PRESSURE PULSE
Authors: Grzesik Jan
Published: August 2021

 We examine herein a simple model for the evolution in time of the pressure which a suddenly vaporized, ablating layer exerts upon the subjacent body. The model invokes a plausible construct of surface material instantaneously thrust into a gaseous regime governed by a Maxwell-Boltzmann phase space distribution. The surface pressure per se is gotten by computing the time rate of change of the momentum per unit area which the retrograde molecules, and only those, transfer through impact/reflection to the unvaporized body below. An explicit pressure formula, one alluding to the variable gas temperature within the vaporized layer, is obtained as a single quadrature requiring numerical integra- tion at finite times past the onset of impact. Limiting, null pressure values, both close-in and in pulse aftermath, can nevertheless be extracted in analytic terms, confirming in particular the indispensable asymptotic evanescence. A universal formula in dimensionless variables is given for pressure versus time, both suitably normalized.
DIBERT: Dependency Injected Bidirectional Encoder Representations from Transformers
Authors: Wahab Abdul , Sifa Rafet
Published: August 2021

In this paper, we propose a new model named DIBERT
which stands for Dependency Injected Bidirectional Encoder
Representations from Transformers. DIBERT is a variation of
the BERT and has an additional third objective called Parent
Prediction (PP) apart from Masked Language Modeling (MLM)
and Next Sentence Prediction (NSP). PP injects the syntactic
structure of a dependency tree while pre-training the DIBERT
which generates syntax-aware generic representations. We use
the WikiText-103 benchmark dataset to pre-train both BERT-
Base and DIBERT. After fine-tuning, we observe that DIBERT
performs better than BERT-Base on various downstream tasks
including Semantic Similarity, Natural Language Inference and
Sentiment Analysis.
L2 and L1Trend Filtering: A Kalman Filter Approach amodification
Authors: Kheirati Roonizi Arman
Published: August 2021

$\ell_2$ and $\ell_1$ trend filtering are two of the most popular denoising algorithms that are widely used in science, engineering, and statistical signal and image processing applications. They are typically treated as separate entities, with the former as a linear time invariant (LTI) filter which is commonly used for smoothing the noisy data and detrending the time-series signals while the latter is a nonlinear filtering method suited for the estimation of piecewise-polynomial signals (\eg, piecewise-constant, piecewise-linear, piecewise-quadratic and \etc) observed in additive white Gaussian noise. In this article, we propose a Kalman filtering approach to design and implement $\ell_2$ and $\ell_1$ trend filtering % (QV and TV regularization) with the aim of teaching these two approaches and explaining their differences and similarities. Hopefully the framework presented in this article will provide a straightforward and unifying platform for understanding the basis of these two approaches. In addition, the material may be useful in lecture courses in signal and image processing, or indeed, it could be useful to introduce our colleagues in signal processing to the application of Kalman filtering in the design of $\ell_2$ and $\ell_1$ trend filtering.

In Vitro Conservation of Medicinal Plant St. John’s Wort (Hypericum perforatum L.) Through Dilution of Basic Medium
Authors: Syahid Sitti Fatimah
Published: August 2021

In vitro techniques could be applied for plant conservation through minimal growth. Growth reduction is generally attained by modifying the culture medium and/or the environmental condition. Conservation of St. John’s wort (Hypericum perforatum L.) in vitro through dilution of basic medium was conducted at the Tissue Culture Laboratory of Indonesian Spice and Medicinal Crops Research Institute (ISMCRI) in 2018. Sterile shoots were cultured into Murashige and Skoog (MS) medium by reducing macronutrients. The treatments used were full-MS + 0.1 mg L-1 N6 - benzyladenine (BA) as control; ¾ MS + 0.1 mg L-1 BA; ½ MS + 0.1 mgL-1 BA and ¼ MS + 0.1 mg L-1 BA. Observation of the culture growth was conducted three months after the treatments. The experiment was arranged in Completely Randomized Design with ten replications. The result showed that the use of a dilution of basic medium affected the growth of St. John’s wort. The use of ¼ MS + 0.1 mg L-1 BA composition could suppress culture growth (number of shoots, shoots length and number of leaves), without showing necrotic symptom until three months of conservation. This treatment could be used as an alternative to minimize the culture of St. John’s wort for in vitro conservation.
Roadway Lighting’s Effect on Pedestrian Safety at Intersection and Midblock Crosswalks
Authors:   Virginia Tech Transportation Institute, Bhagavathula Rajaram , Gibbons Ronald ,   Virginia Tech Transportation Institute, Kassing Andrew ,   Virginia Tech Transportation Institute
Published: August 2021

This study evaluates the visual performance of four intersection lighting designs and five midblock crosswalk lighting designs along with two pedestrian safety countermeasures (rectangular rapid flashing beacons and flashing signs) at three light levels. The study involved a pedestrian detection task, which was completed at night on a realistic roadway intersection and a midblock crosswalk. The results from the study showed that driver nighttime visual performance at intersection and midblock crosswalks was influenced by the lighting design and light level. Intersections should be illuminated to an average horizontal illuminance of 14 lux (1.3 fc). This light level ensures optimal visibility of pedestrians regardless of the lighting design (or luminaire layout) of the intersection. The average horizontal illuminance of 14 lux (1.3 fc) also increases the visibility of pedestrians when glare from oncoming vehicles is present. The 14 lux (1.3 fc) average horizontal illuminance is valid for all lighting designs evaluated except the lighting design that illuminated the exits of the intersection. When the exits of the intersection are illuminated, an average horizontal illuminance of 24 lux (2.2 fc) is needed to offset the disability glare from opposing vehicles. Midblock crosswalks should be illuminated to an average vertical illuminance of 10 lux (0.9 fc) to ensure optimal pedestrian visibility. Where overhead lighting is available, midblock crosswalk lighting designs that render the pedestrian in positive contrast are recommended. Where overhead lighting is not available, crosswalk illuminators can be used to illuminate midblock crosswalks. At night, pedestrian crossing treatments such as rectangular rapid flashing beacons and flashing signs should not be used for pedestrian visibility at midblock crosswalks. Pedestrians crossing treatments should be used in conjunction with overhead lighting or crosswalk illuminators at the established vertical illuminance to ensure optimal pedestrian visibility at midblock crosswalks.

Sobre la diversidad sexual en la escuela
Authors: Castelar C. Andrés Felipe
Published: August 2021

El texto presenta un acercamiento a la diversidad sexual y de género desde una perspectiva “Queer”, con el fin de reconocer su lugar en el cambio cultural que se le exige a la escuela hoy. La fórmula sexo-género es vista como un sistema clasificatorio que puede ser desafiado en vez de asumirlo como real y normativo para la educación. Al desnaturalizar las producciones del lenguaje, dadas como verdades, y poner en tensión las desigualdades propias de la Modernidad, se espera que la diversidad opere  como estrategia de convivencia.

Published: August 2021

Pastures are a major low cost source of feed in beef cattle. Their sustainable use and management affect to the economic performance of farms and to their conservation as a natural resource. Pastures are the subject of agronomic, zoos engineering and economic research, which report negative trends in their territorial scope, composition and productivity as a whole. In beef cattle breeding, the long-term goal is to use high-productivity pastures, which will increase the yield of meat from them, because poor pastures require feeding the cattle with other feed, which reduces profitability. The purpose of this paper is to offer a sustainable pasture management model incorporating agro-technical and organizational activities in beef cattle farms that can increase their economic effectiveness.

Expert System Using Naive Bayes Method in Identifying Caries Disease in Human Teeth
Authors: Hari Tio Ramadan Sapto , Sumijan S
Published: August 2021

Caries disease in human teeth is a disease that permanently destroys the inner walls of teeth and forms small holes in the teeth. The Indonesian people lack the knowledge to find information and identify tooth decay, which makes many people unaware of the consequences and dangers of this disease. Tooth decay disease is usually caused by three factors. The first factor is teeth and saliva, which are the hosts of microorganisms in the oral cavity. Bacteria and food are the second and third factors. The purpose of this research is to help the public find information about tooth decay, thus forming a branch of artificial intelligence, the expert system. Artificial intelligence is a science that allows you to build computer systems that display intelligence in different ways. An expert system is a computer program or information system that uses some knowledge of an expert. The methods used in this study are the Naive Bayes method and the model's view controller, which are implemented as a database in the PHP Codeigniter framework and MySQL. The data processed in this study is knowledge about the symptoms of dental caries obtained from experts. The test results of this method provide patients with the knowledge necessary to prevent tooth decay, with an accuracy rate of 83.61%. This expert system helps the public to recognize and obtain information about tooth decay. The Expert System can also be used to take the first step in preventing tooth decay.
Conditions of solvability of the nonlocal boundary-value problem for a differential-operator equation with weak nonlinearity
Authors: Il'kiv Volodymyr , Strap Nataliya , Volyanska Iryna
Published: August 2021

We study the solvability of a nonlocal boundary-value problem for a differential equation with nonlinearity. The linear part of the equation has complex coefficients which together with the coefficient in nonlocal conditions are considered to be the parameters of the problem.
The area of change of each parameter is limited by a complex circle with its center at the origin. The nonlinear part of the equation is given by a smooth function that satisfies, together with its derivatives, some conditions of growth in the Dirichlet--Fourier space scale.
The proofs are based on the differentiable Nash--Moser iteration scheme, where the main difficulty is to get estimates of the interpolation type for the inverse linearized operators obtained at each step of the iteration. The estimation is connected with the problem of small denominators which is solved, by using a metric approach on the set of parameters of the problem.

Vitamin D is a fat soluble vitamin and a steroid hormone with endocrine, paracrine and autocrine actions. The two major forms are vitamin D2 (ergocalcifeol) and vitamin D3 (cholecalciferol), the active hormone being calcitriol. The importance of vitamin D and its metabolites lies in the key role in calcium homeostasis and bone metabolism but vitamin D also has extraskeletal effects, still incompletely understood. Vitamin D receptor (VDR) is ubiquitous in the body, the presence of VDR in multiple tissues suggesting a more general role of calcitriol. Vitamin D can regulate many cellular functions such as cell proliferation, differentiation, and apoptosis. Calcitriol exerts immunomodulating and antiproliferative effects and plays a potential role in the prevention and therapy of various cancers (breast, colorectal, prostate, thyroid), autoimmune diseases (rheumatoid arthritis, systemic lupus erythematosus, inflammatory bowel disease, multiple sclerosis and type 1 diabetes, thyroid autoimmunity), obesity and also in cardiovascular, renal, maternal-fetal pathologies. Conclusions. The current studies bring increasingly more evidence about the benefits of vitamin D supplementation in extraskeletal pathology although there is no agreed protocol in this regard. However, these patients should be considered for adequate intake of vitamin D for the prevention, improving the evolution and the prognosis of their disease.

Background. Violence against women is a major public health problem. Violence against pregnant women has serious health consequences for both pregnant women and child. Purpose. Using an online search on Pubmed our aim was to make a review of consequences of intimate partner violence against women, emphasizing the size of the impacts on pregnant women, pregnancy and child and aspects of the involvement of health providers. Method. The following key words have been on Pubmed introduced: “intimate partner violence“, “violence against women“, “pregnant women“, “pregnancy outcomes“, “prenatal care“. We reviewed research with a high evidence level published in the last five years, using the Pubmed, Cochrane database as well as WHO and EU documents until August 2016. Results. Most women are reluctant to reveal the phenomenon, but there are some who would consider acceptable for doctors to systematically ask about violence if the patient has certain injuries or features. Prenatal care is an opportunity for early identification and prevention of recurrence of such violence against women. Conclusion. The consequences of intimate partner violence against women pregnant are important and serious consequences on both short and long term health of the woman and the child. Health professionals should be prepared formal urgently to recognize situations that might be caused or complicated by IPV and how to react in these situations.

Ultrasound is an extremely useful tool of thyroid investigation showing different aspects from previously unknown nodules to high-risk lesions requiring immediate surgery. We aim to introduce a pictorial assay of a series cases from two tertiary Romanian centres of endocrinology underling different scenarios from detection to management. All female patients associated normal thyroid function and lack thyroid antibodies while thyroid ultrasound proved essential in detection and follow-up the thyroid condition. Case 1 is a 49-year old subject admitted after an episode of palpitations and detected with a left thyroid nodule of 4.9 by 2.7 by 4.9 cm with inhomogeneous pattern and relatively regular shape requiring surgery. Case 2 is a 63-year old patient accusing dizziness and requiring Doppler ultrasound for carotid arteries that incidentally pointed a thyroid nodule. Ultrasound confirmed a right lobe nodule of 1.1 by 0.6 by 1 cm in association with another small thyroid nodule of 0.8 by 0.6 by 0.6 cm having egg shell peripheral calcifications. Fine needle aspiration was indicated and follicular aspects were identified. Case 3 is a 56-year old female admitted for menopausal osteopenia and routine ultrasound found a hypo-echoic nodule of 2.5 cm at right lobe. Case 4 is a 67-year female who was actually post-operatory confirmed with pT3aN1M0 papillary cancer starting from a first ultrasound evaluation of the thyroid. Case 5 is a 23-year old patient with a nodule detected by ultrasound three years ago and currently appreciated with a considerable increase even BETHESDA 2 was found initially through fine needle aspiration. Conclusion. As pointed by present series of cases, thyroid ultrasound represents an essential method in the hands of endocrinologists.

Although significant progress has been made in recent years in plastic and reconstructive surgery procedures, there are still many issues to be solved. Thus, autologous fat transplantation is one of the promising treatments for soft tissue augmentation and facial rejuvenation, due to the lack of incisional scarring and complications associated with foreign materials. However, unpredictable problems and a low rate of graft survival due to partial necrosis occur. Recent research has led to the development of new adipose tissue transplantation techniques, with promising results, without establishing a standard protocol.

Introduction. Hops (Humulus lupulus L.) is used as a raw material for the production of beer but has also biological properties. Phytoestrogens present in the hops have an antioxidant, anti-inflammatory and probiotic role, while having an effect on the diseases of osteoporosis, diabetes and vasomotor effects (calf) during menopause. Material and method. 8-prenilnaringenine was prepared according to a modification of the initial method. To a cooled solution of naringenin was added a methanolic sodium methoxide solution and prenyl bromide. Results and discussions. The estrogenic effect has been attributed to substances such as β-acids, β-sitosterol, xanthohumol and desmethylxanthohumol. Further investigations have shown that 8-prenylnaringenine is a major hops estrogen. 8-prenilnaringenin acts on estrogen receptors that mediate bone osteoblastic formation and inhibit osteoclastic bone resorption.

The vaginal procedures for uterine prolapse and/or vaginal vault prolapse are based on the attachment of the vaginal apex at the sacrospinous ligament (SL), the uterosacral ligaments (USL) or the iliococcygeus fascia. The fixation at the sacrospinous ligament (SSL) known as sacrospinous ligament fixation (SSLF) is the most studied and performed method for apical prolapse repair. Generally, it is preferred for cases of vaginal vault prolapse post-hysterectomy compared with the suspension at the uterosacral ligament (USLS) that it is usually performed at the time of uterus removal. Due to its associated high rate of recurrence, especially prolapse of the anterior vaginal wall, SSLS has been progressively abandoned in the favor of other modern vaginal procedures such as the Saba Nahedd technique. However, the frequently reported esh associated complications, there are still logical reasons to continue the performance and development of the SSLF technique. In order to assess the current frequency of application and effectiveness of SSLF we have made a review on the recently published literature on the SSLF technique focusing on the rate of success and recurrence, the peri-and postoperative complications, its impact on the daily activities and sexual function. We have selected systhematic reviews, follow-up and retrospective studies as well as metanalyses which have been published in the last 10 years in the german or english language. The aim of this article is to describe the SSLF technique and its advantages in the treatment of sever uterovaginal or vaginal vault prolapse.

Aim. The purpose of this study is to reveal the safety and efficacy of biomaterials used in VPP in the treatment of vertebral spinal vertebral patients and primary vertebral tumors. Material and method. The retrospective study (December 2012-December 2015) included 21 patients admitted to the Sanador Hospitals Department of Neurosurgery and Clinical Orthopedics-Traumatology and Osteoarticular TBC "Foişor", Bucharest, with VPP indication. Patients were diagnosed with vertebral spindles produced by vertebral metastases and primary vertebral tumors without compression in the vertebral canal. The diagnosis of these vertebral compressions has been established and confirmed by medical history, medical history, paraclinical investigation studies: column and face colorectal radiographs, native and contrast vertebral CT, 3D bone reconstruction and reconstruction, and native vertebral MRI contrast. Results. All VPPs have been technically successful, being well tolerated by patients, improved spinal algal symptomatology, rapid postoperative resumption of patient mobility. There were no major postoperative complications such as material migration into the canal, pulmonary embolism with material, infections, postoperative local haematomas, local or systemic reactions to VertaPlex®. All 21 patients were relieved with improved general condition without major postoperative complications. Clinical follow-up data over a 12-month period, detailed at 1, 3, 6, and 12 months after VPP and assessed with visual analogue scale, the Oswestry Disability Score Index and the Karnofsky Performance Scale have demonstrated, along with technical success, a significantly reduced rate of clinical pain, an improvement in disability and a real increase in quality of life and mobility in patients selected for study. Discussions. PMMA still prevails in choosing as a biomaterial in VPP but is not intrinsically degradable, which is a major barrier to wider applications. In order to eliminate the drawbacks of classical VPPs, new bone cements with biodegradable CPC potential have been generated, with a lower toxic potential than PMMA, and which can be improved by bone-stimulation-enhancing elements. Conclusions. VPP actually increases the quality of life of patients with vertebral spine caused by vertebral metastases and primary vertebral tumors. Biodegradability and biocompatibility, minimal exothermic reactions and insignificant contraction imply that biodegradable and mechanically assembled bone cements without graft rejection will be the future of VPP biomaterials.

The therapy of dento-maxillary annomalies involves the use of orthodontic forces acting on the teeth, periodontium and alveolar bone, producing changes in their structure, resulting in final dental movement. The application of orthodontic forces should be done with extreme caution to avoid the occurrence of traumatic root resorption or aggravation when acting on a weak ground. The article aims to identify the particularities of orthodontic treatment in the etiology of external traumatic root resorbtions.
