Intelligent Space Thermal Control Radiator Based on Phase Change Material with Partial Visible Transparency

Coating structures with dynamically adjustable infrared emissivity are crucial in spacecraft components to cope with the transient thermal environments of space. For a long time, thermochromic phase change materials have been widely used in applications requiring emissivity adjustment, and optimizing the range of adjustable infrared emissivity has always been at the forefront of research. However, reducing the absorption of solar radiation has significant implications for the practical application and thermal stability of spacecraft components in space environments. In this paper, we propose a multilayer film structure based on the phase change material VO2 combined with the materials ZnSe and ITO to achieve low solar radiation absorption and adjustable infrared emissivity for intelligent thermal radiators in space. Through finite element simulation analysis of the structure, we achieve a solar radiation absorption rate of 0.3 and an adjustable infrared emissivity of 0.49. According to Stefan–Boltzmann’s law, the structure exhibits strong radiative heat dissipation at high temperatures and weak energy dissipation at low temperatures to maintain the thermal stability of the device and ensure efficient operation. The intelligent thermal radiator operates based on the principles of Fabry–Perot resonance. Therefore, the multilayer structure based on the phase change material VO2 demonstrates excellent performance in both solar radiation absorption and adjustable infrared emissivity, showcasing its tremendous potential in the field of intelligent thermal control in aerospace.

Simple numerical X-ray polarization models of reflecting axially symmetric structures around accreting compact objects

ABSTRACT We present a series of numerical models suitable for X-ray polarimetry of accreting systems. First, we provide a spectropolarimetric routine that integrates reflection from inner optically thick walls of a geometrical torus of arbitrary size viewed under general inclination. In the studied example, the equatorial torus is illuminated by a central isotropic source of X-ray power-law emission, representing a hot corona. Nearly neutral reprocessing inside the walls is precomputed by Monte Carlo code stokes that incorporates both line and continuum processes, including multiple scatterings and absorption. We created a new xspec model, called xsstokes, which in this version enables efficient X-ray polarimetric fitting of the torus parameters, observer’s inclination and primary emission properties, interpolating for arbitrary state of primary polarization. Comparison of the results to a Monte Carlo simulation allowing partial transparency shows that the no-transparency condition may induce different polarization by tens of per cent. Allowing partial transparency leads to lower/higher polarization fraction, if the resulting polarization orientation is perpendicular/parallel to the rotation axis. We provide another version of xsstokes that is suitable for approximating nearly neutral reflection from a distant optically thick disc of small geometrical thickness. It assumes local illumination averaged for a selected range of incident angles, representing a toy model of a diffuse corona of various physical extent. Assessing both xsstokes variants, we conclude that the resulting polarization can be tens of per cent and perpendicularly/parallelly oriented towards the rotation axis, if the reflecting medium is rather vertically/equatorially distributed with respect to a compact central source.

Welfare fragmented information effects: The cost-benefit analysis and Trade-offs

<p class="MsoNormal" style="margin-top: 12pt; text-align: justify;"><span lang="EN-US" style="font-family: 'times new roman', times, serif; font-size: 14pt;">We offer an extensive analysis of the significance of information within the realm of Gaussian quadratic economies. We build upon the seminal papers of Morris and Shin (2002, 2007) and consider a signal game of incomplete information. Particularly, we question the suitability of partial transparency portrayed by fragmented information in addition to the private signal in terms of welfare effects. We can summarize our findings in two main points. First, fragmented information, in conjunction with a private signal, can reduce the reliance on public signals. Second, a conflicting effect arises between increasing full disclosure and increasing the precision of fragmented (semi-public) information when examining different complex scenarios, involving for example endogenous private information or imperfect correlated signals. For a critical threshold, an optimal communication strategy designed by fragmented information should be implemented whenever that kind of information is acquired at a high precision.</span></p>

The COVID-19 Pandemic Response and Its Impact on Post-Corona Health Emergency and Disaster Risk Management in Türkiye

The COVID-19 pandemic, which has affected the entire world, has not only created a number of emerging issues for each country, especially in the field of public health, but has also provided a number of opportunities for risk management, alternative strategies and completely new ways of looking at challenges. This brief report examines the COVID-19 pandemic response in Türkiye and the possible implications of the experience for future responses to other health emergencies and disaster risk management, based on the lessons learned. This study uses publicly available literature from government, private sector and academic sources to analyse the conflicts, changes and lessons learned during the COVID-19 pandemic, which are components of the World Health Organization (WHO) Health Emergency and Disaster Risk Management (Health EDRM) framework. The COVID-19 experience in Türkiye has several aspects, including the significant role of healthcare workers, the existence of an effective health system accustomed to emergencies, applications based on information technologies, the partial transparency of public authorities in providing information and a socio-cultural environment related to cooperation on prevention strategies, including wearing masks and vaccination. Challenges in Türkiye include distance learning in schools, lockdowns that particularly affect the elderly, ensuring environmental sustainability, hesitation about the effectiveness of social/financial support programs, the socio-cultural trivialisation of pandemics after a while and the relaxation of prevention strategies. Lessons learned from the COVID-19 pandemic include the value of transparency in public health/healthcare information, the strengthening of all aspects of the health system in terms of health workers and the importance of a balanced economy prepared for foreseeable risks.

Governance Assessment of Local Restorative Justice System: A Case Study of Village Court in Bangladesh

Access to local justice resolutions is significant not only for the rule of law but also for human rights, democratic governance, poverty reduction and security. Since many rural residents do not have access to formal courts, local justice resolution, namely village court (VC), is the only restorative mechanism in Bangladesh that is accessible and convenient for the grassroots community. This study investigates the management of restorative justice in Bangladesh and evaluates its effectiveness in terms of participation, accountability and transparency. Using key informant interviews and focus group discussions with Union Parishad officials and locals, the study collected empirical data from 60 respondents, who were purposefully selected from four unions covering two districts in Bangladesh. To understand judicial proceedings and interpret the data accordingly, the research team also observed the hearing procedures of the VC with the permission of the proper authorities. Since the local justice resolution system only handles minor and petty cases related to civil and criminal matters, the study indicates that the VC allows a great deal of popular participation in adjudication processes and ensures partial transparency through an open hearing system without incorporating formal mechanisms of accountability. This analysis also shows that ensuring good governance practices in the VC becomes imperative for impartial and credible justice for the local community. Despite having several gaps in the governance framework and drawbacks, the study concludes that a strengthened restorative justice mechanism might contribute to the performance of the formal judiciary, provide a feasible option for locals, and empower them. Therefore, ensuring good governance requires a comprehensive approach that looks beyond legal and judicial reforms and tackles broader structural, social and economic factors. By exploring governance performance and gaps in the local justice system, the article significantly contributes to the government’s and policymakers’ efforts to measure progress and reduce weaknesses. Although the VC system is still relatively new in many countries, it could be an excellent resource for restorative justice systems across the globe.

X-ray polarization properties of partially ionized equatorial obscurers around accreting compact objects

ABSTRACT We present the expected X-ray polarization signal resulting from distant reprocessing material around black holes. Using a central isotropic power-law emission at the centre of the simulated model, we add distant equatorial and axially symmetric media that are covering the central accreting sources. We include partial ionization and partial transparency effects, and the impact of various polarization and steepness of the primary radiation spectrum. The results are obtained with the Monte Carlo code STOKES that considers both line and continuum processes and computes the effects of scattering and absorption inside static homogenous wedge-shaped and elliptical toroidal structures, varying in relative size, composition and distance to the source. We provide first order estimates for parsec-scale reprocessing in Compton-thin and Compton-thick active galactic nuclei, as well as winds around accreting stellar-mass compact objects, for observer’s inclinations above and below the grazing angle. The resulting reprocessed polarization can reach tens of per cent with either parallel or perpendicular orientation with respect to the axis of symmetry, depending on subtle details of the geometry, density, and ionization structure. We also show how principal parameters constrained from X-ray spectroscopy or polarimetry in other wavelengths can lift the shown degeneracies in X-ray polarization. We provide an application example of the broad modelling discussion by revisiting the recent IXPE 2–8 keV X-ray polarimetric observation of the accreting stellar-mass black hole in Cygnus X-3 from the perspective of partial transparency and ionization of the obscuring outflows.

The effect of transparency and accountability on the prevention of pension fund fraud: a case study of a BUMD in Jawa Barat

Fraud prevention is all efforts made to deter potential perpetrators, narrow the space for movement, and identify activities that pose a fraud risk. This study examines the effect of transparency and accountability on preventing pension fund fraud. The variables in this study consist of transparency and accountability as independent variables and prevention of pension fund fraud as the dependent variable. The measurement scale used in this study is ordinal. The research method used is a survey method with a quantitative approach. The statistical tests used in this study are validity, reliability, normality test, multicollinearity, heteroscedasticity, coefficient of determination, ttest, and Ftest using the Statistical Product Service Solution (SPSS) application version 26. The results of this study indicate that partial transparency has a significant effect on preventing pension fund fraud, while accountability has no significant effect on preventing pension fund fraud. However, simultaneously transparency

Metahouse: Noise‐Insulating Chamber Based on Periodic Structures

AbstractNoise pollution remains a challenging problem requiring the development of novel systems for noise insulation. Extensive work in the field of acoustic metamaterials has led to various ventilated structures which, however, are usually demonstrated for rather narrow regions of the audible spectrum. In this work, the idea of metamaterial‐based systems is further extended, developing the concept of a metahouse chamber representing a ventilated structure for multiple band noise insulation. Broad stop‐bands originate from strong coupling between pairs of Helmholtz resonators constituting the structure. The averaged transmission −18.6 dB are demonstrated numerically and experimentally within the spectral range from 1500 to 16 500 Hz. The sparseness of the structure together with the possibility to use optically transparent materials suggest that the chamber may be also characterized by partial optical transparency depending on the mutual position of structural elements. The obtained results are promising for development of novel noise‐insulating structures advancing urban science.

Carbon-Based Molecular Junctions for Practical Molecular Electronics.

The field of molecular electronics has grown rapidly since its experimental realization in the late 1990s, with thousands of publications on how molecules can act as circuit components and the possibility of extending microelectronic miniaturization. Our research group developed molecular junctions (MJs) using conducting carbon electrodes and covalent bonding, which provide excellent temperature tolerance and operational lifetimes. A carbon-based MJ based on quantum mechanical tunneling for electronic music represents the world's first commercial application of molecular electronics, with >3000 units currently in consumer hands. The all-carbon MJ consisting of aromatic molecules and oligomers between vapor-deposited carbon electrodes exploits covalent, C-C bonding which avoids the electromigration problem of metal contacts. The high bias and temperature stability as well as partial transparency of the all-carbon MJ permit a wide range of experiments to determine charge transport mechanisms and observe photoeffects to both characterize and stimulate operating MJs. As shown in the Conspectus figure, our group has reported a variety of electronic functions, many of which do not have analogs in conventional semiconductors. Much of the described research is oriented toward the rational design of electronic functions, in which electronic characteristics are determined by molecular structure.In addition to the fabrication of molecular electronic devices with sufficient stability and operating life for practical applications, our approach was directed at two principal questions: how do electrons move through molecules that are components of an electronic circuit, and what can we do with molecules that we cannot do with existing semiconductor technology? The central component is the molecular junction consisting of a 1-20+ nm layer of covalently bonded oligomers between two electrodes of conducting, mainly sp2-hybridized carbon. In addition to describing the unique junction structure and fabrication methods, this Account summarizes the valuable insights available from photons used both as probes of device structure and dynamics and as prods to stimulate resonant transport through molecular orbitals.Short-range (<5 nm) transport by tunneling and its properties are discussed separately from the longer-range transport (5-60 nm) which bridges the gap between tunneling and transport in widely studied organic semiconductors. Most molecular electronic studies deal with the <5 nm thickness range, where coherent tunneling is generally accepted as the dominant transport mechanism. However, the rational design of devices in this range by changing molecular structure is frustrated by electronic interactions with the conducting contacts, resulting in weak structural effects on electronic behavior. When the molecular layer thickness exceeds 5 nm, transport characteristics change completely since molecular orbitals become the conduits for transport. Incident photons can stimulate transport, with the observed photocurrent tracking the absorption spectrum of the molecular layer. Low-temperature, activationless transport of photogenerated carriers is possible for up to at least 60 nm, with characteristics completely distinct from coherent tunneling and from the hopping mechanisms proposed for organic semiconductors. The Account closes with examples of phenomena and applications enabled by molecular electronics which may augment conventional microelectronics with chemical functions such as redox charge storage, orbital transport, and energy-selective photodetection.

Semimetal hR6-CaSi2 thin film: A transparent contact for Si optoelectronics

Transparent conducting materials (TCMs) provide low cost and effective solution for the modern optoelectronics. However, simultaneous high electrical conductivity and optical transparency in the near-infrared (NIR) and middle-infrared (MIR) spectral ranges remain challenging. This study proposes thin film of the semimetal calcium disilicide (CaSi2) with hR6 polymorph modification to fill this niche. Investigation of the electrical, magnetoresistance and magnetic properties shed light on its semimetal behavior. CaSi2 film grown on Si substrate demonstrates competitive electrical and optical properties from the NIR to MIR ranges compared to commonly used TCMs reaching maximum transmittance of 47% at an important telecommunication wavelength of 1550 nm in addition to the low sheet resistance of 6.6 Ω/sq, which results in high TCM figure of merit of 0.2 Ω−1. Moreover, demonstrated for the first time partial optical transparency of the CaSi2 in the visible range could significantly heighten its applicability for Si-based optoelectronics.

Intrastromal Fluconazole - Effectiveness in the Surgery of Stromal Abscess in a Horse

Background: Due to its ocular microflora, the equine species is predisposed to develop mycotic ulcers which, when not properly treated, can lead to the formation of a stromal abscess. A stromal abscess occurs through the introduction of microorganisms into the corneal stroma. During re-epithelialization, the foreign body is encapsulated, thus creating a barrier that protects bacteria or fungi from treatment with antimicrobial medication. This framework can end up resulting in blindness due to chronic iridocyclitis, putting the animal's vision at risk. The current work aims to report a case of corrective surgery for stromal abscess in a mare with the administration of intraoperative intrastromal fluconazole, in order to corroborate the effectiveness of the technique. Case: A 9-year-old mare was evaluated, with the complaint that her right eye was closed and “yellowish” and that she had already been treated with intramuscular injectable anti-inflammatory drugs based on flunexin meglumine (Banamine® - 50 mg) for 15 days, referring to a possible ulcer in the right eye. Ophthalmic screening resulted in a negative direct reflex and no threat response in the right eye. Examination of the conjunctiva showed congestion and chemosis. Examination of the cornea of the right eye was negative for Fluorescein and Green Lissamine tests, and opacity and corneal neovascularization were noted. The final diagnosis was a corneal abscess of probable fungal origin secondary to a keratomycosis. After the consultation, complementary blood and biochemical tests were performed, which showed normal results for the species in question, and treatment was started with eye drops based on atropine 1% (Fagra® - 20 mL), ciprofloxacin antimicrobial eye drops (Ciprovet Colirio® - 5 mL), and antifungal eye drops based on ketoconazole 1% (manipulated), in addition to an intramuscular injectable anti-inflammatory based on flunexin meglumine (Banamine® - 50 mg - 1.1 mg/kg SID) and an intramuscular injectable analgesic based on sodium dipyrone (Febrax® - 0.5 g - 15 mL/animal SID) until the day of surgery, which was booked for 3 days later. The surgical intervention was then instituted by the technique of anterior lamellar keratectomy followed by intrastromal hydration with fluconazole and the forming of a bipedicled flap, in order to remove the necrotic tissue and antigenic stimulation factors, while the conjunctival flap aimed to improve blood supply and protect the injured area, thus favoring local healing. For better postoperative quality for the animal, continuation of the same treatment as prior to surgery was prescribed for a period of 15 days. The return of the animal for the removal of the flap was scheduled for 45 days after surgery, however, due to the COVID-19 pandemic, there was a delay of 135 days. When the animal returned the flap was still stable. A second surgery was instituted for the removal of the flap, during which it was possible to affirm that the cornea had recovered total integrity and partial transparency with only a leukoma in the previous location of the abscess.Discussion: The technique of anterior lamellar keratectomy together with the use of a conjunctiva flap for the treatment of stromal abscess in horses is a known technique that is used routinely, although some cases report the formation of a second infection in the same space. However, there are few reports on the use of intrastromal hydration with antifungal medication adjuvant to the surgical technique, which, as shown in this report, proved to be effective since even with the issue of a delay in removing the conjunctival flap, the eye remained whole and there was no second infection. The use of this technique can therefore be indicated for the treatment of stromal abscess in horses, given the safety that the application of intrastromal antifungal provides.Keywords: azole, abscess, stromal, keratectomy, ophthalmology, equine, mare.Descritores: azol, abscesso, estroma, ceratectomia, oftalmologia, equino, égua.

Advance booking discount strategies: Competition, information transparency and spot market

We consider two competing risk-neutral firms (A and B) that can procure raw materials via a forward contract and in a volatile spot market. They produce seasonable products using perishable raw materials. The raw material spot price is affected by their trading behavior depending on the extent of the firms’ market powers. To attract consumers ordering products at a discount price in an advance selling period, Firm A offers an advance booking discount (ABD) strategy and updates the demand and spot price information from the pre-orders. The rival Firm B can either not obtain, partially obtain, or completely obtain pre-order information from Firm A, thereby resulting in information non-transparency, partial transparency, or full transparency, respectively. We initially examine the base case in which Firm A does not offer ABD. We then derive equilibrium solutions under the three cases of information transparency. We find that when the profit margin is high and firms have medium market powers, then Firm A should not offer ABD; otherwise, it should. With ABD, less transparency enables Firm A to set a higher price. Interestingly, the expected profit of Firm B, under certain circumstances, can be higher than in the base case even when Firm B cannot get any pre-order information. On the other hand, when firms have low market powers, partial transparency is profitable for Firm B; otherwise, full transparency is profitable.

New Blockchain Protocol for Partial Confidentiality and Transparency (PPCT)

Running behind new technologies is increasingly becoming a non-circumventable requirement for organisms’ survival. This is not only a strategy to gain a competitive advantage in the market but it is a determinant key for their continuity and persistence. The Blockchain is at the heart of this technological revolution for which transparency, accessibility to the public and the sense of sharing are fundamental properties of its design. Despite its importance, leveraging this technology in an ethical and secure manner by ensuring confidentiality and privacy is a top concern. Through this work, we try to design a new approach to validate transactions within the Blockchain. Entitled "Protocol for Partial Confidentiality & Transparency PPCT", this new protocol makes possible to seek a compromise between the two requirements: Confidentiality & Transparency. It allows introducing a new notion of confidentiality that we have named partial confidentiality. Subsequently, it applies it on the transactions exchanged while ensuring the process of their validations by the different nodes of the Blockchain. In addition, and through the use of hashing and digital signature functions, this protocol also ensures integrity and authentication within its validation process. To present this work, we will first discuss the state of the art on the different current privacy approaches and our motivation behind this work. Then we will explain more about the different stages of this process, its benefits and areas for improvement.

Welfare Effects of Partial Publicity and Partial Transparency in Endogenous Information Acquisition

Welfare Effects of Partial Publicity and Partial Transparency in Endogenous Information Acquisition

INFLUENCE OF TWO ROUND IMPEDANCE NOISE PROTECTION SCREENS ON THEIR EFFICIENCY

The acoustic field of the traffic flow around the noise barriers located on both sides of the sound source has been investigated. The overwhelming number of publications devoted to the topic of noise protection with noise barriers concerns the assessment of the effectiveness of screens located on one side of the noise source. Investigation of the influence of the second screen on the efficiency of the first one, if it was investigated, then only by experimental research. In this work, a theoretical study of the mutual influence of two impedance screens, between which a linear sound source is located, is carried out. The problem is formulated in such a way that it made it possible to apply the method of partial regions for the analytical solution of the problem of finding the sound field around a linear sound source. In this case, the sound source is limited on both sides by impedance screens of appropriate thickness. By their shape, the screens are part of a circle with arbitrary corners and the same radius. When solving the problem, an infinite algebraic system of equations is obtained, which is solved by the reduction method. The results of such studies allow assessing the field both between screens and behind screens. This will make it possible to determine the effect of impedance surfaces simulating partial sound transparency on the acoustic field around such screens. This will allow assessing the effect of soundproofing screens on their effectiveness. Such studies will make it possible to more accurately calculate the sound field levels of traffic flows when using impedance noise barriers. It will also make it possible to reasonably put forward requirements for the minimum oundproofing capacity of the screen structure.

Partial wing transparency works better when disrupting wing edges: Evidence from a field experiment.

Lepidoptera-a group of insects in which wing transparency has arisen multiple times-exhibits much variation in the size and position of transparent wing zones. However, little is known as to how this variability affects detectability. Here, we test how the size and position of transparent elements affect the predation of artificial moths by wild birds in the field. Morphs with transparent elements touching wing borders showed a reduced predation risk, with the effect being the same regardless of the number of wing borders being touched. By contrast, transparent element size had little to no effect on predation risk. Overall, this experiment shows for the first time that transparency offers higher protection when it disrupts prey contour in terrestrial habitats.

PENGARUH SISTEM KEUANGAN DESA, SISTEM PENGENDALIAN INTERN PEMERINTAH, DAN TRANSPARANSI TERHADAP AKUNTABILITAS PENGELOLAAN DANA DESA (STUDI PADA DESA DI KABUPATEN ACEH TENGAH)

The purpose of this study was to examine the effect of the village financial system, government internal control, and transparency on the accountability of village fund management (study on villages in Kabupaten Aceh Tengah). This research is a quantitative research with a questionnaire used as primary data elicitation and interval scale as a measure. The research was conducted in Kabupaten Aceh Tengah. A total of 90 respondents were selected, consisting of Banta, Treasurer, and the head of budgeting. The sampling technique used purposive sampling. The data analysis technique used was multiple linear regression facilitated by SPSS version 25. The results showed that the variables of the village financial system, government internal control system, and transparency had a simultaneous effect on the accountability of village fund management. However, the results of the partial transparency research have no effect on the accountability of village fund management

Interaction and dynamics of two nanodroplets separated by monolayer graphene

Understanding the physical mechanism of wetting transparency of monolayer graphene, or how atoms or molecules located on opposite sides of the atomically thin carbon monolayer transmit molecular interactions (such as van der Waals and electrostatic forces) is of significant importance for many extraordinary applications from scientific and practical perspectives. In the current work, we carried out molecular dynamics simulations to explore the interactions between two droplets (TD) separated by the monolayer graphene under applied electric field. The results indicate that in the absence of the electric field the transmission of molecular interactions can drive migration of two droplets towards each other, implying partial wetting transparency of the graphene. Compared to the cases of single droplet (SD), the critical electric field to induce large deformation is lower for the TD cases. However, the droplet–droplet interactions under strong electric fields suppress the reduction of the number of water molecules in the graphene/droplet interface and the elongation of droplets. To understand the enhancement of interactions between two droplets owing to the electric field, we analyze microscopic structures of interfacial water (dipole orientation distribution and hydrogen bonding). The dipole–dipole interaction through the graphene mainly contributes to the droplet–droplet interactions. It was found that significant deflection of water dipoles for the TD cases occurs as the electric field enhances, but the deflection for the SD cases is smaller and even the droplet is detached from the graphene surface. Our findings provide fundamental insights on the influence of the electric field on molecular interactions between two droplets through the monolayer graphene and clues for developing potential graphene-based nanofluidic applications controlled by external electric field.
