Medical Image Denoising Via Matrix Norm Minimization Problems

This paper presents the matrix completion problem for image denoising. Three problems based on matrix norm are performing: Spectral norm minimization problem (SNP), Nuclear norm minimization problem (NNP), and Weighted nuclear norm minimization problem (WNNP). In general, images representing by a matrix this matrix contains the information of the image, some information is irrelevant or unfavorable, so to overcome this unwanted information in the image matrix, information completion is used to comperes the matrix and remove this unwanted information. The unwanted information is handled by defining {0,1}-operator under some threshold. Applying this operator on a given matrix keeps the important information in the image and removing the unwanted information by solving the matrix completion problem that is defined by P. The quadratic programming use to solve the given three norm-based minimization problems. To improve the optimal solution a weighted exponential is used to compute the weighted vector of spectral that use to improve the threshold of optimal low rank that getting from solving the nuclear norm and spectral norm problems. The result of applying the proposed method on different types of images is given by adopting some metrics. The results showed the ability of the given methods.
On the equivalence of two-dimensional and three-dimensional multibeam microwave lenses

Abstract : This report analyzes the theoretical characteristics of lens-fed multibeam arrays. It is shown that, under proper conditions, it is possible to achieve identical performance from two-dimensional (2D) and three dimensional (3D) lenses with the same number of ports. The proof of this equivalence requires several steps. It is first noted that lenses and multibeam networks can be equivalent in their performance. Then it is shown that multibeam planar arrays can use exactly the same excitations as linear arrays with the same number of elements. This relationship is treated in detail in an appendix. It is then shown that 2D lenses can feed both linear and planar arrays and that 3D lenses can feed both linear and planar arrays. Thus the desired equivalence between 2D and 3D lenses is established. It is shown that this relationship applies to 3D lenses with square and hexagonal planar arrays. The location of the feed array relative to the lens array required to achieve the 2D-3D equivalence is discussed. An experimental demonstration in which a 37-element linear array is fed by a 3D bootlace lens is described. Finally, it is pointed out that the equivalence relationship holds at only one frequency, because the path lengths through the 2D and 3D lenses are different. (Author)
Guest editorialEmerging technologies in emergency situations

1. The role of emerging technologies in emergency situations The world is witnessing an unprecedented upheaval in global operations and supply chains (Azadegan and Dooley, 2021; Scholten et al., 2020). Increasingly occurring natural disasters and the COVID-19 pandemic have plunged organisations into a state of emergency, with many fighting for their very survival (Ivanov, 2020; Queiroz et al., 2020; Schleper et al., 2021). Be they large or small, short-lived or sustaining for some time, emergency situations present a potential risk to an individual’s health and livelihood, organisational and societal welfare and to thewider environment (van deWalle andTuroff, 2008; Sarkis, 2021). Emergency situations typically require urgent action to restore operations to the previous scenario or new strategies for survivability and adaptation to an entirely new context (Ivanov and Dolgui, 2020b; O’Flynn, 2020). Due to the scale and immediacy of these events, a range of actors is often involved, including governments, non-governmental organisations and businesses that need to work together to mitigate threats to life and property. To find a way out of today’s emergency situations, managers urgently require guidance on how to rapidly redeploy operational resources and build resilience (Ivanov and Dolgui, 2021; Remko, 2020). Emerging technologies such as those related to Industry 4.0 are well-positioned to help organisations rebuild and reconfigure their resilience capabilities (Koh et al., 2019; Spieske and Birkel, 2021). Recent scholarly work on emerging technologies has deepened our understanding of Industry 4.0 in a supply-chain context, including research on blockchain (Wamba and Queiroz, 2020), artificial intelligence (AI) (Dwivedi et al., 2019), big data analytics (Fosso Wamba and Akter, 2019; Kache and Seuring, 2017), the Internet of Things (IoT) (Schroeder et al., 2020) and 3Dprinting (Kapletia et al., 2019; Roscoe et al., 2019). However, one area that has received limited scholarly attention is deploying emerging technologies in emergency situations. Technology has always been and continues to act as an enabler of enhanced performance. Despite the scarcity of research, it is clear that emerging technologies can act as a coordination mechanism and flexible manufacturing tool when responding to emergencies (Queiroz and Fosso Wamba, 2021), supporting localised manufacturing close to the point of need (Srai et al., 2020). Recent advancements in digital technologies can enhance planning, mobilisation and management during emergency situations. For example, AI and business analytics can quickly identify populations in distress (Fosso Wamba et al., 2021). Social media combined with big data analytics can coordinate the relief efforts of local volunteers during disasters (Dubey et al., 2019; Guest editorial
EMI reduction in randomized boost rectifier

Low frequency harmonics injection into AC power supply and small power factor are the main disadvantages of conventional rectifiers. By using the high power factor correction circuits (HPFCC) the input current has a sinusoidal form and is in phase with the power supply voltage. By solving the problem of power factor with high frequency switching current mode control, another problem arises-that of high frequency harmonics generated in radio-frequency (RF) range by the converter. Therefore the problem of electromagnetic interference (EMI) must be appropriately treated as well. This paper deals with randomized pulse width modulation (RPWM) strategy for the boost rectifier. The randomized modulation principle is introduced in an ordinary PWM control unit which is widely used in unity power factor correction circuits. Introduction of the RPWM results in smaller increases of the total harmonic distortion (THD) in the input current and consequently neglected decreasing of the power factor. On the other hand, this approach causes the high-order harmonics spectral components to be significantly reduced and dispersed around ordinary spectral lines, which means reduced conducted EMI as well.
POTENTIAL USE OF CARIUM CARVI AND CURCUMA LONGA FOR THE REMEDY OF SKIN AND SOFT TISSUES PATHOGENS

The Pathogens responsible for the skin and soft tissue infections are often prone to develop resistance to antibiotics. A good alternative to this resistance is the use of folk medicine. For this purpose two plants Carium carvi and Curcuma longa , used in folk medicine were tested against the selected pathogens, Staphylococcus aureus , Staphylococcus epidermidis, Pseudomonas aerugenosa and Streptococcus pyogenes. The pathogenswere collected from the patients having skin and soft tissues infections. The isolated pathogens were identified through microscopic studies followed by biological tests using Sigma Aldrich KGaA Merck kit protocol. These plant materials were extracted with MeOH and then portioned among different solvents, based on their polarity. These extracts were then applied against the selected pathogens, using well diffusion assay method and the minimum inhibitory concentration (MIC). The results showed marked antibacterial activity in the chloroform and ethyl acetate extract (18 mm zone of inhibition each) of Carium carvi seeds while the chloroform extract of Curcuma longa showed (21 mm zone of inhibition) promising results. Sensitivity of various extracts of the plant in a concentration dependent manner with significant MIC values was determined. Our findings showed that the extracts of C. longa and C. carvi seeds possess strong antibacterial effects against clinically isolated skin and soft tissue pathogens.
Enhancement of effective area of Bragg waveguide using plasma for communication systems

An efficient study is performed to modify the propagation characteristics of Bragg waveguide using plasma filled core. The proposed Bragg waveguide consists of a low index central region having plasma surrounded by a large number of periodic cladding layers of dielectric with alternating high and low refractive indices. The effect of plasma filled core of proposed waveguide on chromatic dispersion, radiation loss, and effective area is studied. This analysis shows that introducing plasma in the core region of proposed waveguide is a key to achieve higher effective area with small radiation loss. Hence, a trade‐off exists between low radiation loss and high effective area in the proposed waveguide. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:2491–2496, 2015
ASSOCIATION BETWEEN GLYCEMIC INDEX WITH THE COMPLICATIONS PREVALENT IN TYPE 2 DIABETES PATIENTS

The glycemic index or G.I is a measure of the effects of carbohydrates on blood sugar levels. The individuals who followed a low-GI diet over many years are at a significantly lower risk for developing both type 2 diabetes and coronary heart disease than others. Therefore, attempt is made to study the complications prevalent in patients with long-standing diabetes and their co-relation with the glycemic index. Objectives: To calculate the glycemic index (G.I) of the diet (MeanG.I considering dietary chart of one week) of patients with Type2 Diabetes of more than 10 years duration.To study the complications prevalent at the time of inclusion in the study, in these patients with type 2 diabetes of chronic duration.To co-relate the G.I (Glycemic Index) of the diet with the prevalence of complications in patients with type 2 diabetes. Methodology: Patients attending diabetic OPD as well as indoor patients were included . All patients with a history of type 2 diabetes mellitus of more than ten year duration with documented reports for the same were included.Duration of study : 1 yearGlycemic index of the mixed meal consumed by the patient based on this weekly dietary chart was calculated.Study subjects : 102 Data analysis done by SPSS.Ethical clearance was taken. Results and Conclusions: All microvascular or macrovascular complications had a direct co-relation with glycemic index.The maximum glycemic index observed was 124.16 and the minimum was 36.73. The mean glycemic index seen was 72.06.

0.99 mW 3-10 GHz common-gate CMOS UWB LNA using T-match input network and self-body-bias technique

A low-power 3–10 GHz common-gate CMOS ultra-wideband (UWB) low-noise amplifier (LNA) using a T-match input network and the self-body-bias technique is demonstrated. Wideband input impedance matching was achieved by using the proposed T-match input network to improve the input matching at low frequencies. A low supply voltage of 1.1 V (for two VDS drops) was achieved by using the self-body-bias technique to reduce the threshold voltage (Vth) of the transistors, which leads to a low power consumption (PD). At VG=0.77 V, the LNA consumed 2.15 mW and achieved S11 of −10.4 to −35.5 dB, S21 of 10.4 dB, and an average NF of 4.9 dB over the 3–10 GHz band of interest. At VG=0.63 V, the LNA consumed 0.99 mW and achieved S11 of −10.7 to −35.8 dB, S21 of 7.9 dB and an average NF of 6 dB. Both are the lowest PD ever reported for an UWB CMOS LNA with bandwidth greater than 6 GHz.

Effects of social support, hope and resilience on depressive symptoms among patients with newly diagnosed prostate cancer

Background The prevalence of depression symptoms and related modifiable factors in prostate cancer (PCa) are not well evaluated. We aimed to assess the effects of perceived social support, hope and resilience on depressive symptoms in newly diagnosed PCa patients, and to evaluate the role of hope and resilience as mediators of that relationship. Method A cross-sectional study was analyzed in consecutive inpatients with PCa during the months of January 2018 and August 2019. A questionnaire was administered to 667 patients. All registered patients were all volunteers and anonymous. Depressive symptoms, perceived social support, hope and resilience were measured anonymously. Out of 667 patients, a total of 564 effective respondents became our subjects. Hierarchical linear regression was used to identify the factors associated with depressive symptoms. Asymptotic and resampling strategies were used to conduct the mediating effects of hope and resilience Results The prevalence of depressive symptoms was 65.9% in PCa patients . Hierarchical regression analyses indicated that perceived social support, hope, and resilience together accounted for 27.5% variance of depressive symptoms. Support from family, hope, and resilience significantly associated with depressive symptoms, respectively. Hope (a*b = -0.0783, BCa95% CI:–0.134 to–0.0319, p < 0.05), and resilience (a*b = -0.1315, BCa95% CI:–0.1894 to–0.0783, p < 0.05) significantly mediated the association between perceived social support and depressive symptoms. Conclusions The high prevalence of depressive symptoms among newly diagnosed PCa patients should receive more attention. Perceived social support, hope and resilience could be positive resources for combating depressive symptoms, and hope and resilience mediated the association between perceived social support and depressive symptoms. Enhancing social support, particularly the support form family, and improving patients’ outlook and resilience may be potential targets for future psychosocial interventions aimed at reducing depressive symptoms.
Consideration of fuel requirements for supersonic transport operation

An analysis of the interaction of operational environment and aircraft characteristics of the supersonic transport (SST) in the areas of design-range and reserve-fuel requirements has been made. Design-range requirements are considered in relation to the effects of wind, temperature, flight-level assignment, and payload variation. An approach toward combining en route and holding reserve requirements while maintaining protection equivalent to that provided subsonic jet transport operations by the present civil air regulation en route plus holding reserves is given. This approach results in a savings in reserve fuel over that required by separate requirements.
Lean Six Sigma through ISO 9001 standard-based quality management system: an investigation for research

In the recent past, researchers and practitioners have been attempting to integrate various manufacturing managerial models. One of such endeavours has resulted in the conglomeration of Lean manufacturing and Six Sigma concepts under the title 'Lean Six Sigma'. Parallel to this endeavour, few researchers have integrated the Six Sigma concepts with ISO 9001 standard-based quality management system (QMS). However, there has been no significant effort made by the researchers to integrate Lean Six Sigma with ISO 9001 standard-based QMS. This research gap has been indicated and explored further by reporting a literature review in this paper. By conducting this literature review, the research investigations in the direction of drawing synergy out of Lean Six Sigma and ISO 9001 standard-based QMS have been drawn. A roadmap for implementing Lean Six Sigma through ISO 9001:2008 standard-based QMS has also been contributed in this paper.
Relationship between IL-10 and PD-L1 in liver hepatocellular carcinoma tissue and cell lines

Background Programmed death-ligand1 (PD-L1) plays a critical role in host immunity in the setting of cancer progression. Interleukin 10 (IL-10) is a multi-cellular, multi-functional cytokine that regulates cell growth and differentiation and participates in inflammatory and immune responses. The purpose of this study was to clarify the relationship between PD-L1 and IL-10 and their clinical importance in liver hepatocellular carcinoma(LIHC). Methods LIHC patients (n=100) who underwent surgery with preoperative therapy were included in the study. By immuno-histochemical staining, PD-L1, IL-10 and CD8 positive cells were examined in resected specimens. The gene expression levels of PD-L1, IL-10 and Met were detected by qRT-PCR and Western blots, and differentially compared in cancer, adjacent and normal tissues. In cell experiments, the Bel7405 and MHCC97-H cell-lines were incubated with IL-10 or anti-IL-10 antibody, and then PD-L1 and Met expression levels were compared by ELISA and Western blots. The effect of crizotinib and/or IL-10 on the proliferation, invasion and migration of LIHC cell-lines was estimated by CCK8 and transwell assay.Results In tumor tissues, the mRNA and protein levels of PD-L1, IL-10 and Met were higher than those in adjacent tissues. The high expression levels of PD-L1 and IL-10 indicated a poor prognosis. IL-10 reduced the expression of PD-L1 in LIHC cell-lines via Met signaling pathway. Over-expression of PD-L1 in increased the levels of IL-10, and Met in in LIHC tissue and cell lines. The combination of crizotinib and IL-10 were more effective in inhibiting the proliferation, migration and invasion of LIHC cell lines. Conclusions The combination of IL-10 and PD-L1 monoclonal antibody may have therapeutic promise in treating LIHC.
Structure-Astringency Relationship of Anacardic Acids from Cashew Apple (Anacardium Occidentale L.)

Cashew apple presents a characteristic astringency. However, the compounds responsible for this characteristic were not described yet. A cashew apple extract was added to a BSA solution and the compounds before and after precipitation were analyzed by UPLC-QTOF/MSE. The extract astringency was measured on a 5-point scale (0: non astringent and 4: extremely astringent). Among the phenolics detected anacardic acids were identified and evaluated for their astringent effect. In the sensorial tests the cashew apple extract was considered very astringent (average of 2.5). A mixture of anacardic acids, had an average of 1.76 (astringent). The three isolated anacardic acids were evaluated. The in silicoexperiments were performed to analyze mainly the steric factor associated to the binding. The sensory results were confirmed by in silico analysis, indicating that a higher unsaturation degree of the aliphatic chain leads to an astringency increase.
Significance and Removal of Manganese in Water Supplies

Manganese is a common ingredient of impounded water 1 and of many well waters. In public supplies, it causes such difficulties as staining of clothes and plumbing fixtures, "black" water, incrustation of mains, and interferences with the colorimetric chlorine residual test. In industrial supplies, it causes severe economic losses through discoloration of products, specks in finished goods, and reduction of pipeline carrying capacities. The earth's crust consists of approximately 0.1 per cent manganese distributed quite evenly throughout. Plants have the ability to extract and utilize it in their metabolism. It finds its way into water by chemical and biologic processes.2 Chemical reactions are generally presumed to account for the greater part of the manganese in ground water; in stored water, manganese builds up by a combination of biologic and chemical processes working simultaneously. It is difficult to obtain clear-cut
Mach Stem Modeling with Spherical Shock Waves

Abstract : A semiempirical model was developed for the treatment of the Mach stem region of a nuclear airburst. This model predicts the conditions that would be observed by an aircraft or missile as well as the limits of this region in space. The model is based upon current shock theory. Where three shock theory fails to accurately predict physical reality, new relations are developed or empirical data is used. Specifically, this model predicts the path of the triple point, the overpressure, dynamic pressure, time of arrival, and direction of the shock impulse above the ground. An explanation of the development of each prediction is made and compared to actual nuclear or high explosive test data. Additionally, a comparison is made between conventional Mach stem modeling and this model. Unique to this model is a method fo predicting the variation of pressure with altitude above the ground. For low scaled heights of burst, the overpressure found at an altitude of 20% of the triple point height is greater than that on the ground. In addition, the overpressure measured just below the triple points if found to be only 60% of the ground overpressure scaled to altitude. This prediction is radically different than conventional ground overpressures scaled to atmospheric pressure at altitude. The predictions made by this model are verified by nuclear and high explosive test data.
