Resonance-enhanced spectral funneling in Fabry–Perot resonators with a temporal boundary mirror

A temporal boundary refers to a specific time at which the properties of an optical medium are abruptly changed. When light interacts with the temporal boundary, its spectral content can be redistributed due to the breaking of continuous time-translational symmetry of the medium where light resides. In this work, we use this principle to demonstrate, at terahertz (THz) frequencies, the resonance-enhanced spectral funneling of light coupled to a Fabry–Perot resonator with a temporal boundary mirror. To produce a temporal boundary effect, we abruptly increase the reflectance of a mirror constituting the Fabry–Perot resonator and, correspondingly, its quality factor in a step-like manner. The abrupt increase in the mirror reflectance leads to a trimming of the coupled THz pulse that causes the pulse to broaden in the spectral domain. Through this dynamic resonant process, the spectral contents of the input THz pulse are redistributed into the modal frequencies of the high-Q Fabry–Perot resonator formed after the temporal boundary. An energy conversion efficiency of up to 33% was recorded for funneling into the fundamental mode with a Fabry–Perot resonator exhibiting a sudden Q-factor change from 4.8 to 48. We anticipate that the proposed resonance-enhanced spectral funneling technique could be further utilized in the development of efficient mechanically tunable narrowband terahertz sources for diverse applications.

Discrepancies between Objectively Assessed and Self-Reported Daily Social Media Time in the Age of Platform Swinging

Building on Junco’s (2013) study examining the accuracy of self-reported computer-specific time on Facebook, the current study investigates the accuracy of self-reported time on multiple social media (SM) platforms across multiple electronic devices and evaluates whether reporting accuracy is systematically associated with participant sex, individual SM platform in question, or total number of SM platforms used. Participants were 320 college students who downloaded software on their computers, tablets, and smartphones to track their active use of Facebook, Twitter, Instagram, and Snapchat over a 2-week surveillance period and then self-reported their daily average minutes on each platform immediately after. Larger proportions of students over- estimated than under-estimated their use, with the largest overestimations found on Snapchat and Instagram. Relative to males, females logged significantly more SM time and were less accurate in reporting. Overall, the likelihood of substantial inaccuracies in reporting total SM time and time on most individual platforms increased with each additional SM platform participants reported using. Findings from this study cast further doubt on the validity of self-report SM measures in the present SM landscape and underscore the need for either data analytic strategies to adjust for systematic reporting biases or a shift towards objective time-tracking methods.

Electrical, Magnetic Radiation and Power Density Analysis of Electronic Gadgets During Yajna

All of us are aware that the modern mechanical and electrical systems in collaboration with AI, CPS, and IoT have affected our lives drastically. At one end, they have provided ease and comfort. On the other end, the electrical and magnetic radiations emitted by them have threatened the mental and physical fitness. Surprisingly, the Asian Agnihotra process effectively reduces the electrical, magnetic radiations emitting from electronic devices. The chapter deals with the computational analysis of electrical, magnetic radiation, and power density measurement of environmental effects and gadgets after the Homa therapy. In the gap of a specific time, readings were recorded, and it was observed that drastic reduction occurred at the place where Yajna was performed. This gap was curtailed gradually as time increased. The phenomenon can undoubtedly be used to address human health threats due to electronic gadgets in the 21st century. Also, it supports the concepts of smart cities where one can quickly identify the numerous effects of the Yajna process.

Management of Quality, Satisfaction, and Loyalty of Rural Destinations

Tourism is a major global industry that, in its heyday, has become significantly concerned with quality and related themes, satisfaction and loyalty. This chapter aims to identify the factors that influence the quality of a rural destination and the associated visitor satisfaction and loyalty. These factors in turn have an impact on destination management, but also other stakeholders such as tourism entrepreneurs in the destination or residents. In 2020, tourism has undergone significant changes due to the pandemic caused by the SARS-CoV-2 virus. For instance, travel abroad was regulated through government regulations, which caused an increase in demand for rural tourism. As the author's research has shown, some quality factors have undergone significant changes. Even the quality management to achieve visitor satisfaction and loyalty has proven to be very important, especially in the sense that by gaining loyalty at this specific time, it can ensure that visitor numbers are maintained even after the pandemic period when the return of and high growth in overseas travel is expected.

FTS: File Tracking System for Railway Board

The aim of this paper proposes a project based implementation File Tracking System (FTS) used in private and mostly in government sector. This project is built on Railway System using three tier architecture. This application is used to prevent corruption. There are a large number of departments in the Railway Department where file transfer is done from one department to another. The number of files moving within the specific time duration, file allocated to any employee and whether the file has been forwarded or not. Sometimes if someone has to do corruption then they does not send that file forward, seeing all this problem we have developed File Tracking System (FTS), which track the movements of the file within the organization. This application will keep track the movement of files from one desk to another inside the department.

Legal Protection for Indonesian Freelance Workers in Law Number 11 of 2020 Concerning Work Creation: Analysis of Changes in Legal Protection for Freelance Workers in Indonesia after the Omnibus Law

This research aims to review the legal protection for freelancers in Indonesia, stipulated in Law Number 11 of 2020 concerning Job Creation. In-Law no. 13 of 2003 concerning Freelance Employment in Indonesia is claimed not to have a clear legal umbrella. The problems examined in this research include the form of freelance legal relations in Indonesia? And the legal protection for freelancers in Indonesia in Law Number 11 of 2020 concerning Job Creation? This research uses normative methods with a statute, case, and historical approach. The results showed that freelance legal relationships in Indonesia were divided into two categories: freelancers who entered into work agreements through platforms that acted as intermediaries and freelancers who entered into work agreements directly without intermediaries. Previously, there were only additional regulations in the form of Kepmenakertrans No. 100 of 2004 concerning the Provisions for the Implementation of a Work Agreement for a Specific Time, and no specific regulation has been found in Law no. 13 of 2013 concerning Manpower. After the enactment of Law Number 11 of 2020 concerning Job Creation and also Government Regulation No. 35 of 2021 concerning Specific Time Work Agreements, Transfer, Working Time and Rest Time, and Termination of Employment, the legal status of freelance workers in Indonesia has a clear legal umbrella, which is classified as a specific time work agreement (PKWT). This finding also answers the concerns of previous researchers who stated that there is no legal protection for freelancers in Indonesia.

Innovative Evaluation Techniques for Hanok Sustainability Based on Integrative Comfort Indices

This study aims to present integrative evaluation techniques that can assess spatial comfort reflecting the unique value of a vernacular building type in Korea called Hanok. For this purpose, current evaluation indices and methods of official standards for normal building performance were analyzed through previous studies, since any certified tools for Hanok evaluation do not exist. This situation has made relevant markets to be deactivated, although Hanok has valuable meanings as the traditional architecture to be succeeded to the next generation in Korea. Accordingly, specific assessment indices were derived to evaluate the Hanok sustainability especially focused on spatial comfort by using a qualitative field surveys with combined quantitative references. Then, actual resident data were collected from a series of Hanok testbeds for specific time-points including summer and winter solstices on the lunar-year system. As a result, resident data could be employed to reveal the characteristics of comfort performance from those target specimens, and show the tendency of the Hanok comfort by suggested innovative criteria for the market as a clue for its commercial potentials. Accordingly, it was concluded that the proposed techniques and indices could be certified for the Hanok evaluation and applied to the field of associated industries to show its specific values and advantages.

Oncogenic NRAS Accelerates Rhabdomyosarcoma Formation When Occurring within a Specific Time Frame during Tumor Development in Mice

In the Ptch+/- mouse model for embryonal rhabdomyosarcoma (ERMS), we recently showed that oncogenic (onc) H-, K- or NRAS mutations do not influence tumor growth when induced at the advanced, full-blown tumor stage. However, when induced at the invisible ERMS precursor stage at 4 weeks of age, tumor development was enforced upon oncHRAS and oncKRAS but not by oncNRAS, which instead initiated tumor differentiation. These data indicate that oncRAS-associated processes differ from each other in dependency on the isoform and their occurrence during tumor development. Here, we investigated the outcome of oncNRAS induction at an earlier ERMS precursor stage at 2 weeks of age. In this setting, oncNRAS accelerates tumor growth because it significantly shortens the ERMS-free survival and increases the ERMS incidence. However, it does not seem to alter the differentiation of the tumors. It is also not involved in tumor initiation. Together, these data show that oncNRAS mutations can accelerate tumor growth when targeting immature ERMS precursors within a specific time window, in which the precursors are permissive to the mutation and show that oncNRAS-associated processes differ from each other in dependency on their occurrence during tumor development.

PROBLEMS OF LEGAL REGULATION OF ADMINISTRATIVE DELIVERY AND DETENTION

The purpose of this work is to study the problems of legal regulation of administrative delivery and detention in Russian administrative law and the study of possible ways to solve them. This problem is due to the fact that the Code of Administrative Offenses of the Russian Federation. The delivery time is not specified as a measure to secure proceedings on cases of administrative offenses, which is a flaw in administrative legislation and may violate the rights and freedoms of a person and citizen. And the law does not establish the duration of a person’s time in office space and his waiting for the start of legal proceedings which is a serious legislative gap. The novelty of this work lies in the formulation by Autor’s of modern and effective proposals for the revision of individual issues related to measures of administrative proceedings and the reality of solving these problems. The Code of Administrative Offenses of the Russian Federation must be modified accordingly in order to clearly regulate or establish specific time limits for the delivery in police office and the time to wait for the commencement of proceedings. In this paper, the above problems and progressive solutions are discussed in detail.
