Probing Lambda-Gravity with Bose-Einstein condensate
We propose a precise test of two fundamental gravitational constants using a novel detector concept that exploits the dynamics of quantum phononic excitations in a trapped Bose-Einstein condensate (BEC), operable at the scale of table-top experiments. In this setup, the sensitivity is enhanced by approximately two orders of magnitude through the use of a tritter operation, which mixes phononic excitations with the BEC's ground state. The BEC exhibits unique sensitivity to the two key components of the gravitational potential in Λ-gravity: the Newtonian GM/r term and the cosmological constant Λr2. Using state-of-the-art experimental design, we predict that the gravitational constant G could be measured with an accuracy up to 10−17 N m2/kg2, representing an improvement by two orders of magnitude over current measurements. Moreover, this experiment could establish the best Earth-based upper limit on Λ at <10−31 m−2, marking the first laboratory-based probe of the cosmological constant. Additionally, the setup allows for the measurement of the distance-dependent behaviour of each term in the gravitational potential, providing a novel means to test modified gravity theories
Correspondence between Antonio R. Martin, Consul of Spain to Hector Hayashi, September 21, 1944
In this group of correspondence, Hector Haruo Hayashi, a national of Japan, who was living first in an internment camp in Idaho and later in Santa Fe, New Mexico, is owed money from the government of Peru. Hayashi's son, Jorge Hayashi writes on behalf of his father about this money. An official response is sent to both Hector and Jorge Hayashi regarding the payment.Collection of notes, articles, correspondence, photographs, and term papers collected by Yukio Mochizuki, a student at CSU Dominguez Hills, while researching Japanese American incarceration and Japanese Peruvian internment during World War II
Características y rendimiento de la canal de caponcitos caprinos en un sistema de engorde a corral con distintas fuentes proteicas regionales en la ración.
El objetivo del trabajo fue evaluar las características y el rendimiento de res de caponcitos caprinos, utilizando como fuentes proteicas dos tipos de poroto descarte y pellet de soja. Se trabajó con 18 machos castrados de 5 meses de edad, con un peso inicial promedio de 17 Kg, los que se asignaron al azar a tres tratamientos, durante 120 días. Las mediciones de las ganancias de peso, características de la canal se determinaron de manera individual para evaluar si existían diferencias de acuerdo a la ración. Una vez finalizado el período de muestreo de 120 días se procedió a la faena de los animales para medir las características y rendimiento de la canal. Se encontró diferencias significativas en algunas de las variables medidas en las características de la canal, mientras que no hubo diferencia en los valores de rendimiento de la misma. Todos los valores encontrados estuvieron dentro de las medias esperadas para

Multivitamin complex-loaded electrospun polyvinyl alcohol core/shell structure fibers for transdermal delivery system: In-silico and experimental studies.
Transdermal delivery systems offer a controlled and targeted environment for releasing drugs compared to other delivery systems. This study presents the fabrication of polyvinyl alcohol (PVA) fibers with a multivitamin complex (MV) using the electrospinning technique (ES). The research focuses on understanding how various fiber structures, such as core/shell, simple fibers, and ES parameters, affect the MC release mechanism and cell viability behavior.
The vitamin complexes were uniformly encapsulated within the polymeric chains in all structure fibers. PVA simple fibers with and without the vitamin complex don't significantly differ in diameter size. However, the core/Shell fiber has a notable decrease in fiber diameter of 45 %.
The fiber with a core/shell structure resulted in a slower release rate of the vitamin complex than simple fiber. According to the Korsmeyer-Peppas model, the release mechanism observed in our study for the simple fibers is classical Fickian diffusion. Instead, core/shell fibers indicate a more anomalous or non-Fickian behavior.
The structural configurations of the fibers do not result in statistically significant differences in cell viability. This could be attributed to the identical nature of materials used, including the polymer and MV, across all cases.
Finally, a computational chemistry study was used to examine the interaction between polyvinyl alcohol (PVA) and vitamins K3 and B3, like a model of MV. The analysis showed four strong hydrogen bonds between PVA and vitamin B3, whereas the interaction between PVA and vitamin K3 only had one hydrogen bond. Furthermore, the PVA and vitamin B3 interaction had higher energy and was more exothermic and spontaneous than the PVA-vitamin K3 interaction. On the other hand, the PVA-vitamin K4 interaction displayed higher reactivity due to its lower separation energy. In contrast, the PVA-vitamin B3 interaction was more stable
Hector Postigo: The Digital Rights Movement [Audio interview]
Hector Postigo is the author of The Digital Rights Movement: The Role of Technology in Subverting Digital Copyright, in which he presents three case studies of a broad group of loosely knit organizations and individuals that address issues concerning fair use, free speech, privacy, and innovation in the digital environment. None of these concerns are new but the digital medium has changed the social, legal, and economic configuration in which the stakeholders operate. Users are no longer simply passive receivers of content but producers as well. Anyone with a computer can generate new and original online content, or can reuse and remix content in creative ways. This is a real watershed for creation and innovation and the digital rights movement is motivated by a vision of culture as shared and participatory. Expanded conceptions of fair use and free speech are essential to facilitate this vision. Individuals, organizations, and businesses that “own” content through government-granted copyrights have an interest in maintaining control in their works, for commercial and other reasons. The lines dividing users, creators, and content owners are very fluid, so much of this story is about the evolution of legal rules – government regulation – with regards to copyright and digital technology. By looking at three different cases in which the nascent digital rights movement struggled with the owners and producers of technology and commercial media over the meaning of fair use, free speech, and cultural production, Hector Postigo provides a unique perspective on the profound changes that digital technology has set in motion for cultures, economies, and polities.
