Identification of Mackinawite and Constraints on Its Electronic Configuration Using Mössbauer Spectroscopy
Authors: Schröder Christian , Wan Moli , Butler Ian B. , Tait Alastair , Peiffer Stefan , McCammon Catherine A.
Published: December 2020

The Fe(II) monosulfide mineral mackinawite (FeS) is an important phase in low-temperature iron and sulfur cycles, yet it is challenging to characterize since it often occurs in X-ray amorphous or nanoparticulate forms and is extremely sensitive to oxidation. Moreover, the electronic configuration of iron in mackinawite is still under debate. Mössbauer spectroscopy has the potential to distinguish mackinawite from other FeS phases and provide clarity on the electronic configuration, but conflicting results have been reported. We therefore conducted a Mössbauer study at 5 K of five samples of mackinawite synthesized through different pathways. Samples show two different Mössbauer patterns: a singlet that remains unsplit at all temperatures studied, and a sextet with a hyperfine magnetic field of 27(1) T at 5 K, or both. Our results suggest that the singlet corresponds to stoichiometric mackinawite (FeS), while the sextet corresponds to mackinawite with excess S (FeS1+x). Both phases show center shifts near 0.5 mm/s at 5 K. Coupled with observations from the literature, our data support non-zero magnetic moments on iron atoms in both phases, with strong itinerant spin fluctuations in stoichiometric FeS. Our results provide a clear approach for the identification of mackinawite in both laboratory and natural environments.

Authors: Emmanuel Endene , Anggraini Vivi , Syamsir Agusril , Paul Suvash Chandra , Asadi Afshin
Published: December 2020

In this study, we investigated the breakage behavior of a bed of olivine sand particles using a drop-weight impact test, with drop weights of various shapes (oval, cube, and sphere). An Attainable Region (AR) technique, which is a model-free and equipment-independent technique, was then applied to optimize the impact energy during the breakage process and also to get particles in defined particle size classes. The findings revealed that the different drop weights produce products within the three different particle size classes (feed, intermediate, and fine). A higher mass fraction of materials in the fine-sized class (−75 μm) was obtained when the spherical drop weight was used relative to the cubic and oval drop weights. The drop height was found to have a significant influence on the breakage process. The AR technique proved to be a practical approach for optimizing impact energy and particle size during the breakage of a bed of olivine particles, with potential application in sustainable soil stabilization projects.

Authors: Cao Tianyu , Kwon Ohhun , Gorte Raymond J. , Vohs John M.
Published: December 2020

Exsolution is a novel technology for attaching metal catalyst particles onto ceramic anodes in the solid oxide fuel cells (SOFCs). The exsolved metal particles in the anode exhibit unique properties for reaction and have demonstrated remarkable stabilities under conditions that normally lead to coking. Despite extensive investigations, the underlying principles behind exsolution are still under investigation. In this review, the present status of exsolution materials for SOFC applications is reported, including a description of the fundamental concepts behind metal incorporation in oxide lattices, a listing of proposed mechanisms and thermodynamics of the exsolution process and a discussion on the catalytic properties of the resulting materials. Prospects and opportunities to use materials produced by exsolution for SOFC are discussed.
Programmable High-Resolution Spectral Processor in C-band Enabled by Low-Cost Compact Light Paths
Authors: Liu Zichen , Li Chao , Tao Jin , Yu Shaohua
Published: December 2020

The flexible photonics spectral processor (PSP) is an indispensable element for elastic optical transmission networks that adopt wavelength division multiplexing (WDM) technology. The resolution and system cost are two vital metrics when developing a PSP. In this paper, a high-resolution 1 × 6 programmable PSP is investigated and experimentally demonstrated by using low-cost compact spatial light paths, which is enabled by a 2 K (1080p) liquid crystal on silicon (LCoS) and two cascaded transmission gratings with a 1000 line/mm resolution. For each wavelength channel, the filtering bandwidth and power attenuation can be manipulated independently. The total insertion loss (IL) for six ports is in the range of 5.9~9.4 dB over the full C-band. The achieved 3-dB bandwidths are able to adjust from 6.2 GHz to 5 THz. Furthermore, multiple system experiments utilizing the proposed PSP, such as flexible spectral shaping and optical frequency comb generation, are carried out to validate the feasibility for the WDM systems.
Design of Soft Grippers with Modular Actuated Embedded Constraints
Authors: Achilli Gabriele Maria , Valigi Maria Cristina , Salvietti Gionata , Malvezzi Monica
Published: December 2020

Underactuated, modular and compliant hands and grippers are interesting solutions in grasping and manipulation tasks due to their robustness, versatility, and adaptability to uncertainties. However, this type of robotic hand does not usually have enough dexterity in grasping. The implementation of some specific features that can be represented as “embedded constraints” allows to reduce uncertainty and to exploit the role of the environment during the grasp. An example that has these characteristics is the Soft ScoopGripper a gripper that has a rigid flat surface in addition to a pair of modular fingers. In this paper, we propose an upgraded version of the Soft ScoopGripper, developed starting from the limits shown by the starting device. The new design exploits a modular structure to increase the adaptability to the shape of the objects that have to be grasped. In the proposed device the embedded constraint is no rigid neither unactuated and is composed of an alternation of rigid and soft modules, which increase versatility. Moreover, the use of soft material such as thermoplastic polyurethane (TPU) reduces the risk of damage to the object being grasped. In the paper, the main design choices have been exploited and a finite element method (FEM) analysis through static simulation supports a characterization of the proposed solution. A complete prototype and some preliminary tests have been presented.
A review of the ecology and status of the Kerry Lily Simethis mattiazzii (S. planifolia) Asphodelaceae in Ireland
Authors: Lupton Darach , Sheehy Skeffington Micheline
Published: December 2020

The distribution, habitat and genetic diversity of Irish populations of the Kerry Lily (Simethis mattiazzii) are described. All sites known in 2009, centred around Kenmare Bay in SW Ireland, were sampled. The species occurs in a relatively uniform plant community, classified as 4030 Dry Heath within a low-lying coastal heath complex. A preliminary genetic investigation involving analysis of 21 chloroplast and nuclear gene regions revealed no genetic diversity in the samples examined, suggesting that the species in Ireland comprises a number of meta-populations, within one large, single population confined to the Derrynane area on the Iveragh peninsula in South-west Kerry (v.c.H1) and one on the north of the Beara peninsula, across Kenmare Bay from Derrynane, in West Cork (v.c.H3). A sixth site, at Cahergarriff on the south of the Beara Peninsula has since been discovered. Of the 5,750 flowering plants recorded in 2009, the biggest meta-population, which also had the highest plant density, numbered 2,364, on Abbey Island, near Derrynane. Results from two brief surveys in 2020 indicate that the populations have reduced in extent and size since 2009. The genetic results so far suggest that the species is genetically depauperate in Ireland, such that the Irish populations may in fact be only represented by a single, or narrow, founder genotype and may be the result of a one-off introduction. The potential mode of arrival of the species to Ireland is discussed in relation to trade with continental Europe, where its distribution is greatest in SW France and western Iberia. A follow-up genetic study is required to confirm these results and explore a putative point of origin for the species in Ireland. Conservation issues are addressed in the light of these observations.

Authors: Shuvalov V.
Published: December 2020

The article discusses new directions in the development of the architecture of recreational facilities in South-east Asia, which need to be implemented to form a modern recreational and tourist cluster in Bangladesh. The author reveals compositional, spatial-planning, decorative-stylistic, functional and design features in the architecture of recreational objects made of bamboo. It is proposed to build the main accommodation facilities (hotels, hotels, motels, arrival houses and houses with the status of "second homes") and food facilities (cafes, bars, canteens, restaurants) using traditional ecological materials. Modern methods of energy saving, their implementation in the practice of design and construction in countries with hot and humid climates are listed. When designing recreational and tourist complexes, innovative technologies, materials and structures are introduced that increase the comfort of recreational facilities. The government relies on the development of the recreational tourism industry in the country, creating economic advantages in the development of this business in the Republic of Bangladesh, increasing the investment attractiveness for domestic and foreign investors, offering preferential tax and customs regimes for the construction and operation of recreational and tourist facilities. Many facilities of the recreational and tourist industry, built in the period 1980-2010 do not meet modern requirements for energy efficiency, environmental friendliness and aesthetic appeal, which definitely has a negative impact on the recreational attractiveness of some regions of the country, this is especially important for remote and difficult to access areas where created objects.

Published: December 2020

This study aims to understand the relevance of e-commerce tax regulations in Indonesia, which were cancelled by the Government. The method used is applied research with explorative study techniques designed in structured questionnaires and interviews with 15 respondents who were judged to have the right expertise with different backgrounds such as consultants, tax observers, academics, managers, e-commerce entrepreneurs, and policymakers. The results showed that it was necessary to revise tax laws to adjust to the digital era's demands soon. In addition, technological innovation in taxation was considered to reduce administrative costs in terms of tax authorities. Big Data tax management was considered to make tax authorities' performance efficient and can anticipate higher costs. The quality of human resources must support technological innovation to bring up a new profession in the future, namely experts who master tax and technology with the term "Taxologist". Finally, the Government needs to secure Value-Added Tax (VAT) taxes in the short term until a global consensus agreement is reached in 2020.

Makna Persahabatan Sebuah Tinjauan Dari Perspektif Filsafat
Authors: Sudarminta Justinus
Published: December 2020

This article is meant to be a philosophical reflection on the meaning of friendship. As evident from its sub-titles, the article is divided into four parts. First, it deals with the notion of friendship, in which the genuine friendship, or in Aristotle’s term called the perfect form of friendship, is distinguished from the egoistic or the imperfect forms. Referring to Aristotle’s account of friendship, the perfect form of friendship is a friendship in which each friend values the other for their own particular qualities, for their own sake, for their virtuous character and not for the pleasure or utilities they can provide. The imperfect forms of friendship usually do not last long, because the tie of friendship will get loose and finally dissolved when it does not bring either pleasure or utilities each friend wants. Second, following Aristotle, I try to explain why friendship is considered important for human happiness. Third, the element of right and duty that get involved in the personal relation of friendship is being addressed. Finally, due to the increasing importance of online communication nowadays, especially during this pandemic corona virus outbreak, I would like also to address the opportunities and challenges of online friendship or the relation of friendship mediated by social media. In this regard, the opportunity to foster online friendship is bigger under the model of moral friendship according to Kant and Kierkegaard in which universal love is emphasized, and Nietzsche’s model in which the agonistic nature of friendship is highly valued, than under the Aristotle’s model.

Authors: Gegel I Ketut
Published: December 2020

In this paper, the author studies of Communicatio in Sacris as an act of sharing sacraments among Christians. This study begins with the author's observation regarding of relation among Christians at this time. In the past centuries, many dissensions happened and large communities were separated from full communion with Catholic Church. Each excludes others to take part in its own liturgy. However, it should be kept in mind, that unity which Christ willed, stood at the very heart of the Church’s mission. At every era, there have been figures who do not only defend the Church but also open the Church to other Christians, especially, in her liturgical services. It has begun a long the history of the Church. It is sufficient to simply to mention two of them. In 1244 Innocent IV allowed Dominicans to minister separated Christian communities by sharing the Eucharist with them. In modern age, John XXIII who led the 2nd Vatican Council  has brought Catholic Church even more open toward other Churches, giving a wide possibility to share sacraments with non Catholic. The purpose of all these actions is for the goodness of souls. The method used in this article is a qualitative research, by analyzing the Church view of communicatio in sacris. The author analyzed the Church documents: 2nd Vatican Council, Canon Law and other sources, including digital sources to support the analysis. From this study, the author found out that communicatio in sacris in its strict meaning means to share sacraments amongs Christians that becomes an instrument to foster fraternity among Christians.

CERVICAL SMEAR ABNORMALITIES IN HIV INFECTED WOMEN ATTENDING A RURAL HOSPITAL ART CENTER IN TAMILNADU
Authors: Muthiah Jeya Pratheef , M Mareeswari.
Published: December 2020

INTRODUCTION: Cervical cancers are the most common form of cancer encountered in Indian women. Studies from India had reported HIV positive women are 10-11 times more prone for cervical carcinomas than HIV negative women with a recent rise in incidence observed. India started a free antiretroviral therapy (ART) program in 2004 with services extended to rural General Hospitals. Cancer cervix can be diagnosed at a preinvasive stage with repeatative papanicolaou smear (cytological screening) and can be readily preventable.
AIM: Our aim is to determine the prevalence of PAP smear abnormalities among HIV infected women from rural areas coming for ART initiation and the relationship between immunological status and smear abnormalities.
METHODS: As per the Indian National ART program all HIV positive women of reproductive age should undergo PAP smear examination before initiation of ART. All consenting women >18 years of age with history of penetrative vaginal intercourse undergo PAP smear examination. In this observational cohort from 25th June 2011 to 15th January 2012 conducted in Melur ART centre and the cytological reports and the patient clinical and immunological status data was analyzed by using SPSS 17 version.
RESULTS: 102 PAP smears were obtained and classified according to Bethesda classification. Five patients (4.90%) were abnormal. Squamous cell carcinoma was observed in 1 (0.98%) patient with a CD4 count of 580 cells/mm3. High squamous intraepithelial lesions were observed in 2 patients (1.96%) with CD4 counts of 208 & 633 cells/mm3 respectively. Low squamous intraepithelial lesion were observed in 2 patients (1.96%) with CD4 counts of 50 and 385 respectively cells/mm3. Immunological status (CD4 count) correlated with grade of the initial lesion (p=0.10). All the patients with PAP smear abnormalities were referred to Madurai Medical College Hospital for further treatment and follow-up.
CONCLUSION: In our observational study increasing cytological abnormalities in the HIV Infected women were noted. Accordingly, all ART centre and HIV treatment programs should institute comprehensive reproductive health care services for this high-risk groups, including routine Papanicolaou smear screening

A STUDY ON ROLE OF OCTREOTIDE ON OUTCOME OF PATIENTS WITH ACUTE PANCREATITIS
Authors: Lodha Vishal , Sonsale Rajesh , Jadhav Sandip
Published: December 2020

Introduction: Mild pancreatitis is a self limiting disease, while morbidity and mortality is considerably high in cases of severe necrotizing pancreatitis. Octreotide reduces secretion, release and activation of exocrine hormones; there is collection of pancreatic hormones in duct which in return causes irreversible destruction of the exocrine and endocrine pancreatic parenchyma leading to mal-digestion and diabetes. There are lot of controversies in the treatment of acute pancreatitis, so through this study we tried to evaluate whether there is a beneficial role of octreotide or not.
Materials and Method: This case control study was done on patients admitted for the treatment of acute pancreatitis at a tertiary care hospital in Central India. This is retrospective study. The data of inpatient records were taken from the medical records department (MRD) of the hospital. The diagnosis of patients was established on basis of biochemical and radiological investigations. The patients were divided into two groups; cases and control, cases had received octreotide along with fluids (group A) controls received fluids without octreotide (group B). Symptomatic treatment was given in both the groups. Ages of the cases and controls were matched (±3 years). The statistical analysis of data was done and results were obtained.
Results: In this retrospective case control study the records of fifty two patients were selected. The mean age in Group A was 35 ±16.45 years and in Group B 40±17.51 years in Group B (tA/B1.061; p ˂0.294). There were 22 males and 4 females in group A, while 20 males and 6 females in group B. Both the groups were comparable. All the patients in octreotide group survived while there were three deaths in control group. As far as mean hospital stay is was 10 days ± 7.10 in group A while it was 7 days ±3.65 in group B. All the p values for the criteria of study are non-significant. But when we talk about percentage, 11.53% patient died in control group.
Conclusion: In our study we found that octreotide does not affect the final outcome of patients with acute pancreatitis. There is no effect on hospital stay and reduced need of analgesics in patients with acute pancreatitis. Keywords: Acute Pancreatitis; Octreotide; Hospital Stay; Mortality

Published: December 2020

Background: Obesity in children and adolescents is gradually becoming a major public health problem in many developing countries including India, Worldwide obesity has nearly tripled over 340 million children and adolescents aged 5-19 are overweight or obese, the increase is more in children than adult. The magnitude of overweight ranges from 9% to 27.5% and obesity ranges from 1% to 12.9% among Indian children, more in urban than rural area. The current study was carried out to find out the prevalence of obesity and associated risk factors among school children in selected municipal and private school. Materials and Methods: The study was conducted in selected municipal and private co-educational schools in Mumbai, Maharashtra, 200 students of 9th standard were selected by Simple Random Sampling technique. Predesigned and pretested questionnaire was used to elicit the associated factors includes family and individual characteristics of study population. Medical examination was conducted on every Student, it included recording of height, weight, and clinical examination. Height was recorded with the help of stadiometer and weight was recorded using electronic weighing machine with an accuracy of 0.1 kg. BMI in respect of all the students was computed and compared with the standard BMI- for-age chart of WHO. Overweight considered with BMI is between 23.0- 24.9 kg/m2, and Obesity: >25 kg/m2 Result: The overall prevalence of overweight and obesity was found 8% and 14.5% respectively in high school children, only 37% children were in normal weight. Based on BMI status overweight and obesity were observed 11% and 23% in private school, 5% and 6% in municipal school respectively. There were significant association of overweight/obesity with parental qualification; individual risk factors like type of diet, use of junk/fast food, eating habits like eat while watching TV/ mobile, less physical exercise etc. observed among school children. Conclusions: Children of high school belonging to middle socioeconomic group with less outdoor activities and consuming junk foods were more predisposed to overweight and obesity in urban area. To prevent childhood obesity there is a need to educate to all stakeholders, inculcates healthy life styles among children and encouraging children for more physical activity and by incorporating Health and Nutrition education in school curriculum.

Primary pancreatic lymphoma (PPL) is an extremely rare disease, with few cases reported in literature. Clinical manifestations are usually nonspecific and mimic other pancreatic diseases. Owing to paucity of data and experience of PPL, clinico-pathological features, differential diagnosis, optimal treatment and overall outcomes are not well known.
Varicella zoster virus (VZV) is known to cause varicella in children and herpes zoster in adults. Acute pancreatitis caused by VZV is a rare and serious complication, with immunocompromised individuals being primarily affected.
We report a case of VZV associated acute pancreatitis in a patient who was diagnosed and treated for primary pancreatic lymphoma, thus rendering her immunocompromised and susceptible to developing infectious pancreatitis. A 56 year old female patient presented with recurrent vomiting, upper abdominal pain and hyperaesthesia in the right upper quadrant of 2 days duration. Following admission her right sided abdominal pain worsened (stabbing pain) and a diagnosis of acute pancreatitis was confirmed based on elevated serum amylase levels and CT scan findings of pancreatic enlargement. The patient was managed conservatively with intravenous fluids, antibiotics, analgesics and topical acyclovir ointment. The patient continues to be asymptomatic after 5 years of follow up. Though extremely rare, a diagnosis of herpes zoster pancreatitis should be considered in such patients, and prompt treatment initiated to prevent further deterioration and to minimize mortality.
Core tip: Primary pancreatic lymphoma is in itself a very rare disease, and our patient having presented with herpes zoster associated acute pancreatitis in a background of PPL makes this case even rarer. This is probably the first case report of herpes zoster associated acute pancreatitis in an immunocompromised patient due to primary pancreatic lymphoma.

Perforated gangrene uterus is a rare condition with high mortality rate, which is difficult and unable to diagnose in first instance without specific history. A 48 year old woman P3L3 with normal vaginal deliveries, not tubectomised came with clinical features of perforation with peritonitis and underwent emergency exploratory laparotomy and found perforated gangrene uterus. Total Abdominal Hysterectomy with Salpingectomy done and specimen shows necrosis of the tissue. Awareness of many etiologies for peritonitis is of great importance when a fatal infection may be the cause of the condition. The most common cause of gas gangrene is clostridium perfringens.

Background: Bacterial vaginosis (BV) is the most common cause of abnormal vaginal discharge and malodor in women of reproductive age. BV reflects a shift in normal vaginal flora to mixed anaerobic and gram negative flora increasing the vaginal pH, which eventually increases vulnerability to sexually transmitted diseases and complicates pregnancies. The objective of this study was to evaluate the accuracy of vaginal pH individually and its combinations with other factors of Amsel’s criteria to diagnose bacterial vaginosis.
Methods: The study was carried out in gynaecology department in K.V.G. Medical College Hospital, Sullia over a period of 6 months. Vaginal swabs of women complaining of white discharge pv were collected using 2 sterile swabs. One, to prepare wet mount and to assess for amine test, other for Grams staining. Vaginal pH was measured using pH strips. A total of 105 patients were checked for the confirmation of Bacterial Vaginosis according to the Amsel’s Criteria and Nugent’s Scoring.
Results: The prevalence of bacterial vaginosis is 39% by Amsel’s criteria and 33% by Nugent’s scoring. Comparing with Nugent scoring methods, the clinical diagnosis by Amsel’s criteria had sensitivity of 85.3%, specificity of 95%. Vaginal pH individually had a sensitivity of only 73.4%. Combination of vaginal pH test with clue cells had highest sensitivity while vaginal pH test with whiff test was comparatively less sensitive.
Conclusion: Amsel’s criteria diagnosis can be simplified by using a combination of 2 criteria, pH of secretions and presence of clue cells but if lab equipment is unavailable, using vaginal fluid pH can still produce moderately accurate results.

HOW TELEMEDICINE HAS CHANGED SURGICAL PRACTICE IN COVID PANDEMIC
Authors: Kumar Praveen , Huda Farhanul , Basu Somprakas
Published: December 2020

Background—The history of telemedicine parallels the history of communication and information technologies. With the advancement in information and communication technologies, telemedicine has also progressed. Still, it could not gain a respectable place in the healthcare delivery system due to lack of clear guidelines, lack of multidisciplinary approach to patient management, onerous privacy regulations, lack of reimbursement, lack of human touch in teleconsultations, and lack of integration with the national health system. There is a need to promote telemedicine services by looking into the current framework and bringing necessary changes to ease the delivery of services. Also, proper training of health care professionals about digital communication to improve patient outcome, and the introduction of telemedicine in medical education so that medical students do not suffer in the present scenario of COVID-19.
Methods- We searched MEDLINE, Embase, PubMed, and PubMed Central. We used free-text terms and MeSH terms such as telemedicine, telemedicine, and COVID 19 pandemic, telemedicine and medical education, telemedicine pitfalls. Data regarding the guidelines of telemedicine and waivers during the pandemic, the current status of telemedicine in the healthcare delivery system, and its promotion during the epidemic were extracted. Finally,43 articles were found suitable to be considered for writing this evidence-based review.
Results—Telemedicine has proven to be an important tool to reduce the risk of transmission of COVID 19 without hampering patient care,medical education and research. With relaxation of existing guidelines in most of the countries and training of healthcare professionals to introduce digital empathy it can be closer to a usual patient-provider encounter.
Conclusion—Telemedicine cannot replace regular face to face patient-provider encounters, but it can be helpful, especially during the times of pandemics as happening during current circumstances. It should be included in the health care delivery infrastructure with all guidelines and legality to help the existing system during normal conditions and take over in need of time.
PUBLIC DISTRIBUTION SYSTEM AND COVID-19 : A NARRATIVE REVIEW

Without definite measures, the latest global health crisis COVID-19 can lead to a food security crisis. (Fan, 2020) World Health Organization (WHO) confirmed the spread of pandemic to 216 countries with over 10 million active cases.(WHO, 2020) With the massive rate of transmission, the disease has even indirectly infected the other realms of society as well. The global economy is already struck by the inevitable, lasting recession posing deeper social and political amendments.(Pathak et al., 2020) Governments imposing lockdowns constrained inter-state transport and international travel restrictions have disrupted the logistics and supply chain for the manufacturers, distributors, and consumers as well. United Nations Conference on Trade and Development presented a report claiming the automotive commerce (-47%), elementary material productions (-116%) and energy industry (-208%) are the hardest hit sector by COVID-19, cutting the global investment by 40%. (UNCTAD, 2020) Financial problems, downsizing, limiting access, increased job insecurity, reduced income localized price hikes, shortage of labors due to out-migration, and others are significant apprehensions. UN Department Economic and Social Affairs stated that at the worst extreme, the global economy could even condense by approximately 1% in 2020. (Press Trust of India, 2020) The crisis scenario can only be improved by harmonized decisions, international solidarity, innovative policymaking, and firm decisions by leading global economies.

Published: December 2020

Information on rice phenological stages from Synthetic Aperture Radar (SAR) images is of prime interest for in-season monitoring. Often, prior in-situ measurements of phenology are not available. In such situations, unsupervised clustering of SAR images might help in discriminating phenological stages of a crop throughout its growing period. Among the existing unsupervised clustering techniques using full-polarimetric (FP) SAR images, the eigenvalue-eigenvector based roll-invariant scattering-type parameter, and the scattering entropy parameter are widely used in the literature. In this study, we utilize a unique target scattering-type parameter, which jointly uses the Barakat degree of polarization and the elements of the polarimetric coherency matrix. Likewise, we also utilize an equivalent parameter proposed for compact-polarimetric (CP) SAR data. These scattering-type parameters are analogous to the Cloude-Pottier's parameter for FP SAR data and the ellipticity parameter for CP SAR data. Besides this, we also introduce new clustering schemes for both FP and CP SAR data for segmenting diverse scattering mechanisms across the phenological stages of rice. In this study, we use the RADARSAT-2 FP and simulated CP SAR data acquired over the Indian test site of Vijayawada under the Joint Experiment for Crop Assessment and Monitoring (JECAM) initiative. The temporal analysis of the scattering-type parameters and the new clustering schemes help us to investigate detailed scattering characteristics from rice across its phenological

stages.

Published: December 2020

This paper introduces a novel shallow self-supervised tensor neural network for volumetric segmentation of brain MR images obviating training or supervision. The proposed network is a 3D version of the Quantum-Inspired Self Supervised Neural Network (QIS-Net) architecture and is referred to as 3D Quantum-inspired Self-supervised Tensor Neural Network (3D-QNet). The underlying architecture of 3D-QNet is composed of a trinity of volumetric layers viz. input, intermediate and output layers inter-connected using a 26-connected third-order neighborhood-based topology for voxel-wise processing of 3D MR image data suitable for semantic segmentation. Each of the volumetric layers contains quantum neurons designated by qubits or quantum bits. The incorporation

of tensor decomposition in quantum formalism leads to faster convergence of the network operations to preclude the inherent slow convergence problems faced by the self-supervised networks. The segmented volumes are obtained once the network converges. The suggested 3D-QNet is tailored and tested on the BRATS 2019 data set extensively in the experiments carried out. 3D-QNet has achieved promising dice similarity while compared with the intensively supervised convolutional network-based models 3D-UNet, Vox-ResNet, DRINet, and 3D-ESPNet, thus facilitating annotation free semantic segmentation using a self-supervised shallow network.

Published: December 2020

Recently, Wang-Wang have discussed a two birds with one stone: two-factor authentication with security beyond conventional bound. We find that this scheme is vulnerable to the password exposure attack and also does not offer user anonymity, which is an important feature for some of the applications like e-healthcare services, e-banking, etc. In this paper, we provide the solution to these problems.
