Suvremene promjene sastava stanovništva Srednje Like prema dobi i sektoru djelatnosti — primjena prostorne i demogeografske analize
Authors: Hamzić Marta
Published: March 2022

Glavni je cilj rada utvrđivanje suvremenih promjena sastava stanovništva Srednje Like prema dobi i prema sektoru djelatnosti. U tu svrhu provedene su prostorna i demogeografska analiza korištenjem popisnih podataka za godine 1971. i 2011. na prostornoj razini jedinice lokalne samouprave (kao i njihovih sjedišta) te za Srednju Liku u cjelini, a opažanja na terenu pridonijela su razumijevanju utjecaja utvrđenih procesa na prostor, odnosno krajolik Srednje Like. Također, kako bi se dobio bolji uvid, provedena je analiza kretanja ukupnog broja stanovnika Srednje Like u razdoblju od druge polovine 20. stoljeća. Promatrajući dob stanovništva, rezultati istraživanja su pokazali kako je u promatranom razdoblju na svim promatranim razinama došlo do značajnog starenja stanovništva čime dobno-spolna piramida poprima oblik urne. Pri tome je za obje promatrane godine najveća ostarjelost stanovništva zabilježena u Općini Lovinac, a najmanja u Gradu Gospiću. Nadalje, u promatranom je razdoblju zbog starenja stanovništva na području Srednje Like opća stopa aktivnosti sve niža. Također, došlo je do prestrukturiranja stanovništva prema djelatnostima tercijarnog i kvartarnog sektora uz napuštanje tradicionalnih primarnih djelatnosti. S obzirom na trenutačne okolnosti, u narednim popisima stanovništva očekuje se na analiziranom području daljnji nastavak izrazito nepovoljnih demografskih i ekonomskih procesa.

Authors: Koznarska-Buczkowska Agnieszka , Chilicka Karolina , Rusztowicz Monika , Adamczyk Ewa
Published: March 2022

Background: Oily skin can be extremely problematic for sufferersand presents a great challenge for cosmetologists. This condition is characterized by an excessive amount of sebum on epidermal surface and enlarged skin pores.Modern cosmetology is able to offer a wide range of treatments that are able to reduce excess sebum secretion, and an appropriate diagnosis and cosmetic interview will allow for the selection of a suitable cosmetic treatment. If there are no contraindications for device treatments and the client is not allergic to cosmetic products, an ultrasound treatment called sonophoresis may be used. Green tea is obtained from both the leaves and buds of the Camellia sinensis plant. The active ingredients of green tea are polyphenols, which have antimicrobial, anti-inflammatory, and antineoplastic properties. Thanks to modern cosmetic devices, we are able to use green tea and sonophoresis to introduce this preparation into the skin.
Aim of the study: The aim of this study was to evaluate the effectiveness of a sonophoresis treatment on oily skin in a 20-year-old female.
Case report:The participant reported issues with too much sebum on the epidermis. The sebum level was measured before and after a series ofsonophoresistreatments using a sebumeter (DermaUnitSCC3). For the treatment, an ultrasound device and a cosmetic ampoule containing green tea extract were used. The entire cosmetic procedure consisted of 4 treatments performed at weekly intervals.
Conclusions: After the series of cosmetological treatments, there was a significant reduction in sebum secretion.Thus, the use ofsonophoresis and a green tea ampoule turned out to be a great help in reducing epidermal sebum. The participant also noticed that her skin had less sheenfollowing the series of treatments.The resultsindicate that the sonophoresis procedure is safe and effective.

Current Trends in Developmental Genetics and Phylogenetic Patterns of Flower Symmetry
Authors: Puri Renu , Rustagi Anjana
Published: March 2022

Flower Symmetry is a key evolutionary innovation in some lineages of angiosperms. The flowers of the primitive angiosperm plants were radially symmetrical actinomorphic. Later bilaterally symmetrical zygomorphic flowers independently evolved in several clades of angiosperms. This transition of trait is associated with an adaptation to specialized methods of pollination. Zygomorphic flowers allow more specific plant insect interaction. So, the transition from radial symmetry to bilateral symmetry facilitates reproductive isolation which in turn might have led to diversification or rapid speciation of some lineages in angiosperms. Phylogenetic analyses in lineages of angiosperms revealed that few clades have shown that there have been reversals, that is, there is transition from bilateral symmetry to radial symmetry. When such studies are correlated with genetic studies, it is revealed that CYC (TCP family) transcription factors are responsible for the transition of this floral trait. Phylogenetic analyses, genetic studies and Evo-Devo analyses can answer important questions such as what other transition in floral symmetry is found in angiosperms? Is there a pattern of floral symmetry transition in different lineages? Do these transitions act as key innovation for the clades in which they have evolved?
Abiotic Stress Response in Brachypodium
Authors: Gandour Mhemmed
Published: March 2022

Understanding the mechanisms of physiological response in plants is crucial to building sustainable agriculture, especially under the current worldwide climate and environmental crises. Thus, plants that successfully acclimate to stress can decrease growth under stressful conditions. Brachypodium, an undomesticated grass species with close evolutionary relationships to wheat and barley, is a promising model organism of crop research. It can grow under various conditions and possess specific adaptations or tolerance mechanisms. Hence, it promises to greatly accelerate the process of gene discovery in the grasses and to serve as bridges in the exploration of panicoid and pooid grasses, arguably two of the most important clades of plants from a food security perspective. Brachypodium could hence efficaciously acclimate to the drought, salinity, cold, heat, and nutrient stress variations by reversible hypo (hyper)-activation of specific genes or sustaining transcription states as well as by reducing growth and osmotic adjustment. Nonetheless, B. stacei and B. hybridum have more plasticity and more adaptiveness than B. distachyon to abiotic stress. This review will describe advancements in knowledge of the physiological and metabolic adjustments that are needed for abiotic stress tolerance.
Phalloplasty in Transgender Men with and without Urethral Lengthening
Authors: Salgado Christopher , Yu Kerstin , Kenel-Pierre Stefan , Gheiler Edward , Shao Tony
Published: March 2022

Our goal in trans man phalloplasty is to decrease the patient’s level of gender incongruence, obviate the use of an external prosthesis, be able to orgasm, and give the patient the ability to urinate standing (if desired), while also attempting to decrease urinary complications. The decision to undergo urethral lengthening is considered early in this surgical process. However, urethral complications are among the most common problems we see in phalloplasty, and surgical techniques have evolved to decrease these complications. We have developed an advanced two-stage mucosa-only prelaminated neourethra phalloplasty technique to address these issues. Our surgical technique is detailed in addition to providing patient demographics, co-morbidities, flap complications, and urinary sequelae. We also discuss the perineal urethroplasty in patients opting for no urethral lengthening in phalloplasty. All options should be given and risks considered in trans men undergoing soft tissue phalloplasty, and these will be discussed in detail.
Determination of Pesticides Residues in Bee Products: An Overview of the Current Analytical Methods
Authors: Mejías Enrique , Garrido Tatiana
Published: March 2022

The presence of undesirable compounds in honey and other bee products may modify their biological attributes. Such molecules may be present because of different human activities (i.e., pollutants, pesticides) or because of veterinary treatments designed to control and prevent diseases that affect bees. The use of pesticides in agricultural crops has been related with negative effects with and acute damages for bees. The widespread agricultural use of neonicotinoids is a common exposure pathway for bees, and it may be an important factor in declining bee health. In 2013, the European Union has forbidden the use of three pesticides belonging to the neonicotinoids: Imidacloprid, Thiamethoxam, and Clothianidin after the analysis of several scientific results of some studies where those pesticides were involved in an increased death of bees.
Intensity Modulated Radiation Therapy Plan (IMRT) Verification Using Indigenous Heterogeneous Phantom
Authors: Raina Payal , Singh Rashmi , Barthakur Mithu
Published: March 2022

The dose distribution given by intensity-modulated radiotherapy (IMRT) is highly conformal, compared to conventional radiotherapies; however, due to the presence of the large numbers of fields and irregular shape and size of the treatment segments, the accuracy of IMRT delivery needs to be verified via dose measurement. Different dosimetry techniques are available that measures part of or the whole treatment immediately before a patient is treated and give us the total treatment delivery picture. But the majority of the commercially available phantoms are of homogeneous density, whereas the actual human body is a complex medium of different density patterns. Additionally, the very few heterogeneous phantoms, which are available commercially (i.e., anthropomorphic phantoms) are very costly and are not procured by most of the radiotherapy centers, especially in developing countries. Therefore, an indigenous heterogeneous phantom has been designed to verify the dose distribution prior to patient treatment.
Inter-Organizational Integration, Transition, and Collaboration in the Project Front-End, and Project Initiation Phase
Authors: Siriram Rajenlall
Published: March 2022

Project management is a complex process involving different stakeholders within and outside the firm. These stakeholders involve among others, the client who has the initial need, and establishes the project requirements and boundaries; the sales teams involved in developing the initial solution and sealing the contract with the client; the project management practitioners responsible for executing the solution as per the contractual requirements; different organizational units, such as engineering, finance, supply chain, health, and safety; and other stakeholders, such as sub-suppliers, legal authorities, consultants, and funding agencies. These stakeholders have different perspectives and objectives that make project management a complex process. In this chapter the challenges, benefits, and opportunities of inter-organizational integration, transition, and collaboration within and between firms in large complex projects are explored. The scope of this chapter is on the interface between the sales front-end phase and the project initiation phase because it is in the sales front-end, where the strategic and operational direction for the rest of the project is set and agreed. A better understanding of this interface may provide opportunities for improvement in project management success.
Implant-Retained Maxillary and Mandibular Overdentures - A Solution for Completely Edentulous Patients
Authors: Knezović Zlatarić Dubravka , Ćelić Robert , Pezo Hrvoje
Published: March 2022

The main goal of modern removable prosthodontics is to restore the normal appearance, function, esthetics and speech in each completely edentulous patient. However, if all teeth are missing in a patient, it becomes very complicated to achieve it using traditional protocols. Therefore, implants were introduced into removable prosthodontics to ensure better retention and stability of the conventional dentures. In case of a large amount of bone missing in the jaw it is necessary to ensure the functioning of the dentures constructing various additional stabilizing and retentive prosthodontic solutions on the osseointegrated implants. Numerous types of attachment systems have been used recently for relating implant-retained overdentures to underlying implants: basically splinting (various bar shape designs) and non-splinting attachments (various ball type attachment, magnet attachment, telescopic coping systems). Indications for their use depend on the surgical and prosthodontic factors such as the number and position of the implants, the amount of free intermaxillary space and the type and size of the overdentures. Different indications, types of the overdentures and the attachment systems will be discussed in this chapter.

Published: March 2022

Introduction: Our aim was to measure hepatitis C virus (HCV) screening and linkage-to-care rates in an urban emergency department (ED) before and after implementing an HCV viral RNA (vRNA) reflex testing protocol within a HCV screening program for at-risk patients. Our hypothesis was that using a reflex testing protocol would increase HCV testing rates of at-risk patients in the ED, which would increase the linkage-to-care rate.

Methods: In August 2018, our institution implemented an automated, electronic health record-based HCV screening protocol in the ED for at-risk patients. In January 2019, we implemented an HCV vRNA reflex testing protocol (reflex testing) for all positive HCV antibody (Ab) tests that were initiated through the screening protocol. We compared completion rates of HCV vRNA testing and the rate of linkage to care for patients with positive HCV Ab test results before and after implementation of reflex testing (five months per study period).

Results: Prior to reflex testing implementation, 233/425 (55%) patients with a positive HCV Ab test had an HCV vRNA test performed, whereas 270/323 (84%) patients with a positive HCV Ab test result had vRNA testing after reflex testing implementation (odds ratio [OR], 4.2; 95% confidence interval (CI): 3.0-6.0; P < 0.001). Of the eligible patients with positive HCV Ab test results who could be linked to care, 45 (10.6%) were linked to care before HCV reflex implementation and 46 (14.2%) were linked to care with reflex testing (OR, 1.4; 95% CI: 0.9-2.2; P = 0.13).

Conclusion: Implementing a reflex testing initiative into an HCV screening program in the ED can result in an increase of the percentage of patients who receive an HCV vRNA test after having had a positive HCV Ab. Hepatitis C virus vRNA reflex testing was not associated with a statistically significant increase in linkage-to-care rates for HCV Ab-positive patients; however, further studies are required.

Authors: Waseem Muhammad , Garg Nidhi , Chang Bernard , Acosta Juan , DeAngelis John , McLean Mary , Melville Laura , Pistor Timothy , Shah Kaushal , Tarantelli JoAnne , Wojcik Susan , Gerard Ryan James
Published: March 2022

Introduction: The 2019 novel coronavirus pandemic has caused significant disruptions in the clinical operations of hospitals as well as clinical education, training, and research at academic centers. New York State was among the first and largest epicenters of the pandemic, resulting in significant disruptions across its 29 emergency medicine (EM) residency programs. We conducted a cross-sectional observational study of EM residency programs in New York State to assess the impact of the pandemic on resident education and training programs.

Methods: We surveyed a cross-sectional sample of residency programs throughout New York State in June 2020, in the timeframe immediately after the state’s first “wave” of the pandemic. The survey was distributed to program leadership and elicited information on pandemic-prompted curricular modifications and other educational changes. The survey covered topics related to disruptions in medical education and sought details on solutions to educational issues encountered by programs.

Results: Of the 29 accredited EM residency programs in New York State, leadership from 22 (76%) responded. Of these participating programs, 11 (50%) experienced high pandemic impact on clinical services, 21 (95%) canceled their own trainees’ off-service rotations, 22 (100%) canceled or postponed visiting medical student rotations, 22 (100%) adopted virtual conference formats (most within the first week of the pandemic wave), and 11 (50%) stopped all prospective research (excluding COVID-19 research), while most programs continued retrospective research.

Conclusion: This study highlights the profound educational impact of the pandemic on residency programs in one of the hardest- and earliest-hit regions in the United States. Specifically, it highlights the ubiquity of virtual conferencing, the significant impact on research, and the concerns about canceled rotations and missed training opportunities for residents, as well as prehospital and non-physician practitioner trainees. This data should be used to prompt discussion regarding the necessity of alternate educational modalities for pandemic times and the sequelae of implementing these plans.

Published: March 2022

Introduction: Millions of people present to the emergency department (ED) with chest pain annually. Accurate and timely risk stratification is important to identify potentially life-threatening conditions such as acute coronary syndrome (ACS). An ED-based observation unit can be used to rapidly evaluate patients and reduce ED crowding, but the practice is not universal. We estimated the number of current hospital admissions in the United States (US) eligible for ED-based observation services for patients with symptoms of ACS.

Methods: In this cross-sectional analysis we used data from the 2011-2015 National Hospital Ambulatory Medical Care Survey (NHAMCS). Visits were included if patients presented with symptoms of ACS (eg, chest pain, dyspnea), had an electrocardiogram (ECG) and cardiac markers, and were admitted to the hospital. We excluded patients with any of the following: discharge diagnosis of myocardial infarction; cardiac arrest; congestive heart failure, or unstable angina; admission to an intensive care unit; hospital length of stay > 2 days; alteplase administration, central venous catheter insertion, cardiopulmonary resuscitation or endotracheal intubation; or admission after an initial ED observation stay. We extracted data on sociodemographics, hospital characteristics, triage level, disposition from the ED, and year of ED extracted from the NHAMCS. Descriptive statistics were performed using sampling weights to produce national estimates of ED visits. We provide medians with interquartile ranges for continuous variables and percentages with 95% confidence intervals for categorical variables.

Results: During 2011-2015 there were an estimated 675,883,000 ED visits in the US. Of these, 14,353,000 patients with symptoms of ACS and an ED order for an ECG or cardiac markers were admitted to the hospital. We identified 1,883,000 visits that were amenable to ED observation services, where 987,000 (52.4%) were male patients, and 1,318,000 (70%) were White. Further-more, 739,000 (39.2%) and 234,000 (12.4%) were paid for by Medicare and Medicaid, respectively. The majority (45.1%) of observation-amenable hospitalizations were in the Southern US.

Conclusion: Emergency department-based observation unit services for suspected ACS appear to be underused. Over half of potentially observation-amenable admissions were paid for by Medicare and Medicaid. Implementation of ED-based observation units would especially benefit hospitals and patients in the American South.

Published: March 2022

Background: This study aimed to investigate the relationship between depression and pain anxiety with pain catastrophizing in patients with coronavirus disease 2019 (COVID-19). Methods: In this descriptive, correlational study, 180 patients with COVID-19 in Akhtar and Imam Hossein hospitals in Tehran, Iran, were included from March 2019 to April 2020. All participants completed three questionnaires, including the Pain Catastrophizing Scale (PCS), Pain Anxiety Symptoms Scale (PASS), and Beck’s Depression Inventory (BDI). The data were analyzed using Pearson correlation coefficient and multivariate regression. Results: There was a positive and significant relationship between the dimensions of rumination, magnification, and helplessness with total score of pain catastrophizing, as well as moderate to severe dimensions with total pain anxiety and depression in patients with COVID-19. Conclusions: According to the results of regression analysis, pain anxiety based on pain catastrophizing dimensions was statistically significant, so that rumination, magnification, and helplessness could predict pain anxiety and explain a total of 15.1% of changes in pain anxiety. Also, depression was statistically significant based on dimensions of pain catastrophizing, so rumination, magnification, and helplessness could predict the patients’ depression and explain 13.6% of depression changes.

Simone de Beauvoir’s discussion of the place of aging and menopause in The Second Sex offers only brief glimmers of older women’s agency tucked in among descriptions of the female elderly frantically, but futilely, searching for meaningful roles. Aging is particularly difficult to think through from an existentialist perspective that emphasizes agency and control over one’s world. Beauvoir’s later work in The Coming of Age offers more carefully detailed perspective for considering aging and the meaning of the sacrifice of life’s projects. The difficulty of maintaining a sense of identity and meaning increases as agency becomes limited and the weight of one’s past life and decisions becomes greater. Moving from The Second Sex to The Coming of Age in dialogue with Beauvoir clarifies when loss of control and agency destroys life’s value, but also when a deliberate choice to sacrifice agency may be meaningful and value-laden.
Broken Windows, Naloxone, and Experiments in Policing

The practice of equipping police officers with naloxone has generated controversy within the profession. I adjudicate the disagreement in this article. I diagnose the dispute as rooted in a philosophical account of professional, role-based obligations. Parties to the debate appear to agree that what the police are permitted to do is determined in part by the (disputed) essential goal of the police profession. Instead, I argue that we should make room for “experiments in working.” Finally, I argue that naloxone use by police is an experiment in working that falls squarely within the tradition of order maintenance policing.

Published: March 2022

According to the Law on Accounting of the Republic of Serbia, all companies are obliged to compile regular (annual) financial reports. Regular financial statements include: balance sheet, income statement, statement of changes in equity, statement of other results, cash flow. The financial statements provide the necessary information about assets, liabilities, equity, income, expenses, cashflow, external and internal users. The aim of the research is to show the significance and importance of compiling quality financial reports. The subject of the research is the financial statements of the Jaffa company. Jaffa Crvenka was taken as an example of how domestic companies can compile clear, accurate and timely financial reports. The result of the research showed that it is not enough to compile only traditional financial reports, but it is also necessary to provide additional information from non-financial reports, all with the aim of satisfying the information needs of various state holders.
Strategic leadership and organizational learning

Organizational learning is a fundamental strategic process and the only sustainable competitive advantage in the future. Unfortunately, despite the increased interest in this topic, researchers said very little specifically about the role of director-generals and top management teams in the implementation of organizational learning in their firms. However, theorists of strategic leadership argue that top managers are key to firms' outcomes because of the decisions they are empowered to make since, in the end, they are responsible for what happens in the organization. Although there is an implicit assumption that the strategic leaders are the leading force behind organizational learning, researchers have not defined specific behaviors and mechanisms through which leaders influence learning. While huge budgets are spent on learning, databases and "new learning departments", director-generals and top managers have no instruction on how their reactions speed up or slow down learning. Strategic leadership and organizational learning have remained largely unrelated research fields.

The culture of continuous improvement, as an efficient and effective example of the Toyota factory organization, has found its application in organizations of different types and different process designs. The top and middle managers of the most successful companies in the most developed economies, such as Japan or Germany, know very well how difficult it is to change the organizational culture and implement changes in the existing corporate culture, regardless of the type and size of the change. The paper identifies the key limitations that the management of a furniture company in Serbia encounters in implementing the KAIZEN culture of continuous improvement, the problems they have solved on the threshold of KAIZEN implementation, and the problems that slow down the process of continuous improvement. An in-depth interview was used for the purpose of data collection, and the interviewee was the general manager of a furniture manufacturing company. In the discussion and concluding considerations of the paper, several suggestions for overcoming the problems and several guidelines for solving them were given.

As a new technique for the deformation of aluminum alloy plate with complex curved surface which is used in shipbuilding, electromagnetic force assisted line-heating process, or EFALH for short, can promote forming efficiency and produce anticipated curved surface within the range of temperatures required in production. For a start, the process unit and experimental scheme for EFALH were introduced in the article. After the experiment, it was confirmed that the electromagnetic force do have auxiliary effect on the deformation of aluminum alloy plate. Then, for the EFALH process, three-dimensional numerical simulation was performed, and the simulated results were verified by experimental data. Influence on the deformation process caused by the difference in the time and current amplitude of electromagnetic force was studied through numerical simulation. At last, the deformation behavior of the plate under EFALH process has been analyzed from two perspectives, namely the periodism of pulsed electromagnetic force and the loading and unloading procedure in the load cycle caused by electromagnetic force.

Uma excelente oportunidade para o Brasil se destacar na economia e na produção científica é aproveitar os recursos renováveis que o país dispõe, como a biomassa lignocelulósica, nesse contexto, as transformações biotecnológicas são apropriadas do ponto de vista ecológico e ambiental, permitindo transformação de recursos naturais renováveis em produtos com altos valores comerciais. E um composto digno de representar esses materiais lignocelulósicos é o álcool coniferol (AC), que é uma biomassa vegetal lignocelulósica sintetizado pela via bioquímica do fenilpropanóide nas plantas, sendo promissor para o desenvolvimento econômico e mitigação de impactos ambientais, ainda, é um composto com alto valor de mercado. Objetivos: Visando contribuir para impulsionar a realização dos propósitos relacionados ao desenvolvimento sustentável, desenvolvimento econômico e mitigação de impactos ambientais, o objetivo dessa pesquisa foi analisar o potencial mercadológico do composto químico (biomassa lignocelulósica) AC e seus derivados. Método: Trata-se de uma revisão integrativa da literatura. Preliminarmente foi realizada pesquisa bibliográfica em livros, artigos científicos e em documentos publicados em bases de dados online. Sequencialmente foi realizado coleta de dados sobre as empresas que vendem o AC, nas próprias plataformas das empresas fornecedoras. Esses dados foram estudados no intuito de obter informações relevantes sobre as empresas que já vendem os compostos e/ou seus derivados, especificação do produto, a quantidade que fornecem dos produtos e quais os preços que estão praticando no mercado, como também, o país que as empresas estão localizadas, endereço, e-mail e telefone. Conclusão: O mercado do AC parece ser restrito, não há evidências concretas na literatura de aplicações claras do uso direto do coniferílico e nem de produtos que o utilizam em suas formulações. Laboratórios de pesquisa são os principais consumidores do AC e/ou seus derivados. Todavia, existem descrições de transformações químicas do coniferol que resultam em compostos com alto valor agregado do produto. Sendo assim, existe uma abrangente oportunidade de negócio, tratando-se de exploração na cadeia de valor de moléculas derivadas do coniferol. Por exemplo, para síntese de princípios ativos e fragrâncias a partir desse composto.

To meet the increasing demand of integrated photonic device design, a LiNbO3/Na surface plasmonic waveguide (LNSPW) is demonstrated, and a directional coupler (DC) based on the LNSPW is also studied. The mode characteristics of the LNSPW and the coupling performances of the DC are simulated by the finite element method (FEM). There are four modes in the LNSPW when its width (w1) and the thickness (h1) are less than 600 nm and 400 nm, respectively. The number of the modes in the LNSPW increases with waveguide size increasing. To achieve the single-mode propagation, w1 and h1 are chosen to be 300 nm and 200 nm, respectively. The effective refractive index (neff), propagation length (Lp), and normalized effective mode area (Aeff/A0) are analyzed with different dimensional parameters of the LNSPW. The value of Lp is ~200 μm, and Aeff/A0 is less than 0.4. In order to demonstrate the electro-optic tunable performance, the normalized output power (Pnorm) values of the DC are calculated based on the LNSPWs with different values of coupling interval (Wgap), coupling length (LC), and operating wavlength (λ). The Pnorm values of the output ports (port 2 and port 3) vary with Wgap and LC. Owing to the electro-optic effect of LiNbO3 (LN), Pnorm of the DC can be adjusted by changing the applied electrostatic voltage (V0). The influence of V0 on Pnorm increases when Wgap is larger than 100 nm and LC is greater than 12 μm. The larger the value of LC and Wgap, the stronger the effect of V0 on Pnorm is, but Pnorm values from two output ports decrease with Wgap and LC increasing. A 3 dB coupler can be achieved by changing V0 to 53 V when Wgap = ~100 nm, LC = ~17 μm, and λ = 1.55 μm, and has good directivity and isolation. The LNSPW provides a feasible scheme to realize the tunable DC, and has potential applications in integratable electro-optic tuanble devices, nonlinear optics, optical signal processing, and optical holographic storage.

Starting from the principle that the integer-period sampling (IPS) of periodic signals is free of spectrum leakage, in this paper we propose the multisine-IPS theory, deduce theoretically the sampling rate setting formula of multisine-IPS condition for the first time, and build its realization method based on field-programmable gate array (FPGA) plus digital-to-analog converter (DAC) plus analog-to-digital converter (ADC). A new multi-frequency electrical impedance tomography (mfEIT) system based on multisine excitation and its IPS theory is developed, and a dual-target imaging model including a carrot stick and a cucumber stick is designed. The experiments of multi-frequency time-difference imaging and frequency-difference imaging are carried out on the mfEIT system. The experimental results show that the newly-designed mfEIT system can achieve full-band impedance measurements on multiple objective tissue boundary at 20 frequency points (2–997 kHz) within one fundamental period (1 ms), and the structure and position of biological tissues with different electrical properties can also be distinguished from the resulting images. The proposed multisine-IPS theory and its implementation method can complete a full-band impedance measurement within one multisine fundamental period, which lays a theoretical and technical foundation for developing high-speed mfEIT system.
