The spatial resolution of $high-T_{c}$ scanning SQUID microscope is limited by the washer size of SQUID and the gap distance between SQUID sensor and the sample. In this work, we tried to improve the spatial resolution of scanning SQUID microscope by reducing the size of SQUID sensor fabricated with $YBa_2$$Cu_3$$O_{7}$ thin film. Outer dimensions of the SQUiDs we tested are 24 $\mu\textrm{m}$ $\times$ $ 28\mu\textrm{m}$, $12 \mu\textrm{m}$ $\times$ $16\mu\textrm{m}$, $12\mu\textrm{m}$ x $12\mu\textrm{m}$, $10 \mu\textrm{m}$ $\times$ $10 \mu\textrm{m}$ each. To operate them in the flux-locked loop scheme, we used a direct-coupled electronics instead of using conventional electronics involving a modulation scheme. Since the direct-coupled feedback scheme does not require modulation current adjustment that poses as a practical difficulty in the SQUID operation in modulation-scheme, the direct feedback operation is rather simpler than the conventional modulation method. The resulting noise features were dominated by the noise of preamp in FLL electronics except that of the largest SQUID. The noise levels of SQUIDs are expected below 1$\times$$10^{-5}$ $\Phi_{0}$H $z^{1}$2/ (at 300 Hz), that is a typical noise level for SQUID made of $YBa_2$C $u_3$$O_{7}$ thin film. The data acquisition and motion-controlling parts were also improved, resulting in faster data acquisition rate and less vibration of the system.m.

When Hart Crane′s poem cycle The Bridge was published in 1930, a group of influential reviewers accused Crane of immaturity, sentimentality, and lack of focus. They condemned crane′s wayward, fuzzy mysticism as backwards-looking and self-defeating. Even sympathetic critics, such as Harold Bloom, have consistently portrayed Crane′s poetry as the pyrotechnic final fizzle of late romanticism. These persistent, public reservations, however, have not prevented an impressive proliferation in secondary literature concerning Crane since the late 1960s. His promiscuity, alcoholism, erratic behavior, relative poverty, tragic death, and total commitment to art have since earned him the labels of New World Rimbaud and proto-Beat. His colorful career thus explains in part his retrospective fame. Nevertheless, living hard and dying young do not guarantee artistic immortality. This article poses questions as to why Crane has mattered so much to subsequent generations of U.S. readers and what these readers find so compelling in his poetry. The answer, I would argue, lies in Crane′s idiosyncratic use of language. Far from striving for transparency, he writes in an inimitably obstructive, artificial manner. There is something seductive and absurd in his wild use of words here, I would further argue, we discover the reason behind both Crane′s enduring appeal and his supposed inadequacy as a writer. Crane did "torture" syntax, semantics, and conventional associations, not because he saw his unusual language as an eccentric mannerism but because he saw it as a tool in the service of constructing a "myth of America" and reintegrating the human and divine. Understanding thy he considered this to be the case clarifies Crane′s achievement and illuminates why his work still seems so relevant today.

Automated road map generation poses significant research challenges since GPS-based navigation systems prevail in most general vehicles. This paper proposes an automated detecting method for intersection points using GPS vehicle trajectory data without any background digital map information. The proposed method exploits the fact that the trajectories are generally split into several branches at an intersection point. One problem in previous work on this intersection detecting is that those approaches require stopping points and direction changes for every testing vehicle. However our approach does not require such complex auxiliary information for intersection detecting. Our method is based on partial trajectory matching among trajectories since a set of incoming trajectories split other trajectory cluster branches at the intersection point. We tested our method on a real GPS data set with 1266 vehicles in Gangnam District, Seoul. Our experiment showed that the proposed method works well at some bigger intersection points in Gangnam. Our system scored 75% sensitivity and 78% specificity according to the test data. We believe that more GPS trajectory data would make our system more reliable and applicable in a practice.

Using hybrid channel affords the benefits of achieving control through the direct channel and achieving flexibility through the indirect channel. However, using a hybrid channel also poses special challenges to a manufacturer, including the problem of managing multiple channel members with disparate goals and priorities. The purpose of this study is to enhance our understanding on the management of hybrid channel. We study marketing channels for fashion apparel to examine governance challenges and solutions of a hybrid channel. We have two objectives to fulfill that purpose. First, we aim to tie two largely separate research streams of salesforce management and marketing channel management together by examining both intrafrim governance and interfirm governance issues under one conceptual framework. Second, we aim to lay a ground work for rigorous further research on this topic by tying two major theoretical approaches of governance together under one conceptual framework. Our predictions were tested with data from the survey of apparel manufacturers and retailers. The analysis results support the predictions moderately.

One of the major problems in fish production is that parasite-induced episodes of disease can result in significant impacts to the health of stock, mortalities and, economical losses. Seabreams are economically important fish in both the capture fishery and aquaculture sectors in Oman and represent potential species for aquaculture. The current study set out to investigate infection of polyopisthocotylean monogeneans on the gills of wild goldlined seabream, Rhabdosargus sarba, caught from Musairah region in Oman. The prevalence, mean intensity and abundance of polyopisthocotyleans on 145 fish was found to be 52.41%, 5.65 and 3.04, respectively. Three species of microcotylid parasite were isolated, one being Atrispinum acarne while the remaining two species require further study to identify them. There was no significant difference in the infection rate between host sex, however, parasite burdens were higher on larger sized fish (p<0.05) and were found to favour the first gill arch (p< 0.05). The study found that the sample of Rhabdosargus sarba landed in the waters around Musairah are heavily infected, with a predominantly immature population of microcotylids. Further work is required to better understand the potential risk each species poses to the health of its host before a decision is made on the suitability of new candidate fish species for commercial aquaculture.

Purpose : The purpose of this study was to investigate the structural relationships between fear of missing out, addictive tendencies toward social network services (SNSs), and depression in colleges. Methods : The target subjects were students in colleges across gyeongnam & busan, to whom the purpose of the study was explained and who spontaneously agreed to participate. A survey was conducted with 302 participants over 31 days from March 7, 2022, and data from 299 responses was analyzed. Results : 1. Women felt a higher fear of missing out than men. 2. Women showed greater inability to control their use of SNSs, more SNS-related disorders in daily life, and greater immersion in and tolerance of SNSs when compared to men. 3. Women were more depressed than men. 4. Positive correlations were observed between the fear of missing out and SNS-addictive tendencies, between the fear of missing out and depression, and between SNS-addictive tendencies and depression. Conclusion : A comprehensive review of these findings suggests that women had overall higher levels of isolation fear, SNS-addictive tendencies, and depression than men. Based on this, universities should provide gender-specific educational programs around these issues; this student cohort will ultimately work in healthcare, and this kind of awareness will be essential for treating patients. Considering that the current situation poses unusual challenges due to the COVID-19 pandemic, the study's results can serve as basic data for planning educational programs in the future. Over the coming years, comprehensive and continuous education and counselling relating to the fear of missing out, SNS addiction, and depression will be urgently required.

In this paper, I will explore disparate voices embedded in the interactions of stories in which personal, cultural, historical, and mythical consciousness brings up diverse ideas about the experiences of Native Americans. The accommodation of differences and changes is clearly manifested through the healing ceremony of Tayo, which poses some practical questions: what could be the authentic tradition of Native Americans?; which direction should it be led to? As these questions suggest, Tayo needs to think over and work through the way that Native oral stories will enrich the signification of being Indian within multicultural U. S. society. In other words, Tayo should transfer the oppositional relationship between Anglo and Native American world into an interactive one to bring forth new meanings concerning their interactions. As a hybrid, Tayo begins to recognize that his fragmented consciousness could represent the pervasive but surmountable anxiety about the cultural clash between Native and White Americans. Going through the multiple layers of his stories, Tayo learns that Native Americans need to hold a balanced viewpoint firmly: this demonstrates that storytelling brings restoration and renewal to him. As a result of Betonie's healing ceremony and his intimate relationship with Ts'eh, Tayo comes to have a holistic comprehension about how all the living things are interconnected to one another. After acquiring this recognition, Tayo succeeds in his quest to get back Josiah's cattle and recovers his identity as a Laguna Pueblo Indian, still letting diverse voices, cultures, and stories flow into the process of storytelling. As the last scene in which the conversations among Tayo, Auntie, and Grandmother took place illustrates, Tayo has newly secured a position that will require him to create a new, alternative story, not just repeating previous stories.

Background: Radiation protection is crucial in various fields due to the harmful effects of radiation. Shielding is used to reduce radiation exposure, but gamma radiation poses challenges due to its high energy and penetration capabilities. Materials and Methods: This work investigates the radiation shielding properties of polyvinylidene fluoride (PVDF) samples containing different weight fraction of tungsten carbide (WC), tungsten trioxide (WO₃), and tungsten disulfide (WS₂). Parameters such as the mass attenuation coefficient (MAC), half-value layer (HVL), mean free path (MFP), effective atomic number (Z_eff), and macroscopic effective removal cross-section for fast neutrons (Σ_R) were calculated using the Phy-X/PSD software. EpiXS simulations were conducted for MAC validation. Results and Discussion: Increasing the weight fraction of the additives resulted in higher MAC values, indicating improved radiation shielding. PVDF-xWC showed the highest percentage increase in MAC values. MFP results indicated that PVDF-0.20WC has the lowest values, suggesting superior shielding properties compared to PVDF-0.20WO₃ and PVDF-0.20WS₂. PVDF-0.20WC also exhibited the highest Z_eff values, while PVDF-0.20WS₂ showed a slightly higher increase in Z_eff at energies of 0.662 and 1.333 MeV. PVDF-0.20WC has demonstrated the highest Σ_R value, indicating effective shielding against fast neutrons, while PVDF-0.20WS₂ had the lowest Σ_R value. The Monte Carlo N-Particle Transport version 5 (MCNP5) simulations showed that PVDF-xWC attenuates gamma radiation more than pure PVDF, significantly decreasing the dose equivalent rate. Conclusion: Overall, this research provides insights into the radiation shielding properties of PVDF mixtures, with PVDF-xWC showing the most promising results.

Corporate design activities have expanded from being exclusive and passive responsibilities to active participation in planning, marketing, technology and corporate brand image differentiation for successful business. Thus the communications between designers and other functions come to include critical decision making, information sharing, and objective reasoning. Given that design activities now have to involve various functions in product development, the styling-related design process, which is still developed by designer's intuition and experience, poses as an obstacle not just between various functions involved, but even within the design function. To overcome this obstacle and to lead more effective design decision process, a means for product form development assessment and management is necessary. This research proposes a foundation for managing and assessing product form based on the hypothesis and demonstration of discovering a system of formative factor and order a product form expresses that can be shared as an objective and logical system. As a result of this demonstration, the form as a unique visual expression and the factors related to the form and its co-relationship are examined. The factors are called formative parameters and the system is named as the product form alignment method. Based on the logic derived from the system, the process for developing an image that aligns with the predefined goal is explained. The method defines a balance between a designer's intuitive creativity and the extracted logic, which can act as a basis for designers to share design language among themselves and for communication between design and other functions. Based on this system, designers are able to align design work with the set goal, and focus and limit the range of form development, which is anticipated to result in lead-time reduction and minimizing unnecessary obstacles and mistakes.

Prolific females require better nutrition and feeding practice because of larger litter size and the substantial decline in body fat. Life-time pig output will be compromised if body protein and fat are not properly managed. First litter females are especially vulnerable because they can loose ${\geq}15%$ of whole-body protein. Conservation of body protein mass during first lactation minimizes wean to estrus interval and increases second litter size (up to 1.2 pigs). The ability to influence litter-size by amino acid nutrition is a new dimension in our understanding. A P2 fat depth below 12 mm at farrow and below 10 mm at wean compromised wean to estrus interval (>2 d) and next litter size (0.5 to 1.5 pigs) in sows. It is now clear that a 'modest' excess of feed during the first 72 h of pregnancy decreases embryo viability so that the potential for an increased litter size at birth is not realized. The capacity for milk production by prolific young sows is 25% higher than the standard used previously (NRC, 1988). First litter females averaged 9.82 kg milk/d for a 21 d lactation. Second and third litter counterparts averaged 10.35 kg/d. Milk production was 95% of peak by 10 d of lactation and sows were in greatest negative energy and lysine balance during the first 6 d. Nearly 45% of the total loss in body protein occurred within the first 6 d, but this could reduced to 30-35% by using a more aggressive feeding strategy after parturition. There appear to be 2 phases in lactation for lysine need (d 2-12 vs 12-21). Feeding to the higher level alleviates the second litter size decline. The lysine requirement for lactation can be predicted with accuracy, but we are not able to predict the second limiting amino acid. Mammary uptake of valine relative to lysine and recent work with practical diets suggest that the recent NRC (1998) pattern is realistic and that threonine and valine could be co-limiting for corn-soy diets for prolific sows nursing 10-11 pigs. Empirical studies are needed to refine the ideal pattern so that synthetic lysine can be used with more confidence. Milk fat output for the elite sow is extraordinary and poses an unnecessarily high energetic cost. Methods that reduce mammary fat synthesis will benefit the sow and may enhance piglet growth.
