Hausdorff dimension in RR-analytic profinite groups

We study the Hausdorff dimension of R-analytic subgroups in an R-analytic profinite group, where R is a pro-p ring whose asso- ciated graded ring is an integral domain. In particular, we prove that the set of such Hausdorff dimensions is a finite subset of the rational numbers.Comment: 7 page

Si Judy Ann Santos at ang Wika ng Teleserye

The actress Judy Ann Santos boasts of an illustrious and sterling career in Philippine show business, and is widely considered the “queen” of the teleserye, the Filipino soap opera. In the manner of Barthes, this paper explores this queenship, so-called, by way of traversing through Santos’ acting history, which may be read as having founded the language, the grammar of the said televisual dramatic genre. The paper will focus, primarily, on her oeuvre of soap operas, and would consequently delve into her other interventions in film, illustrating not only how her career was shaped by the dramatic genre, pre- and post-EDSA Revolution, but also how she actually interrogated and negotiated with what may be deemed demarcations of her own formulation of the genre. In the end, the paper seeks to carry out the task of generically explicating the teleserye by way of Santos’s oeuvre, establishing a sort of authorship through intermedium perpetration, as well as responding on her own so-called “anxiety of influence” with the esteemed actress Nora Aunor

Ilang Eksplorasyon sa Pag-Aaral ng Kulturang Popular sa Filipinas

Pacing Caroline Hau (2002), this essay explores the historical and intellectual specificities of Cultural Studies and the study of Popular Culture in the Philippines, and situates them in the author’s recent study of the cultural history of the teleserye, the Filipino TV soap opera. While the essay assumes that much of the key ideas and paradigms of Western Cultural Studies have been adopted in the country, the ethos of the local field may also be traced back to the works of patriots José Rizal and Isabelo delos Reyes. The projects of the two have been continued by intellectuals and scholars who emerged during the 1960s to the 1970s and formulated more postcolonial approaches to the study of Philippine culture. Moreover, the essay comments on the importance and role of interdisciplinarity in the emergence of Cultural Studies and the study of Popular Culture in the Philippines

Ang Boys’ Love bílang Papausbong na Telebiswalidad (Boys’ Love as Emerging Televisuality)

Sa sanaysay na ito, pinahahalagahan ang sandali ng pag-usbong ng mga boys’ love webserye sa panahon ng pandemya. Sinusulit nito ang telebiswal na penomeno sa pamamagitan ng pahapyaw na pag-uugat sa mga minumulang tradisyon o impluwensiya; sa pagsasakonteksto ng paglaganap nito; sa pangkabuuang pagbása sa nagkakaisang salaysay ng mga serye; at sa pagtukoy sa mga transgresyong tinutupad nito sa anyo at kagawian ng panonood ng teleserye, at sa pangkalahatan, sa telebisyong patuloy na umaagapay sa mga hámon at pagbabago ng kalakaran. Sa kasaysayan ng teleserye at ng telebisyong Filipino, pinangangatwiranang mahalaga ang sandali ng BL sa gitna ng pandemya dahil maituturing itong pagtunggali sa iba’t ibang nibel ng pagkakahon/pag-aaparador ng konserbatibo at mapagtakdang lipunan. Nakikita rin itong paraan ng pagbawi sa naratibo ng bayan matapos likhain ng telebisyon ang halimaw at machong rehimen ni Rodrigo Roa Duterte sa “Duterteserye” ng 2016. (This essay evaluates the momentous rise of boys’ love web series in the time of pandemic. This accounts for the televisual phenomena by way of a cursory tracing of originating traditions and influences; a contextualization of its popular reception; a collective reading of its unifying narrative; and an appraisal of the transgressions it brought to the form and viewing practices of teleseryes, and at large, to television which continues to come to terms with the challenges and changes in broadcasting. This essay argues that in the history of the teleserye and Philippine television, the moment of BL in the middle of the pandemic may be considered a means to counter, in many levels, the containment inflicted by the conservative and oppressive society. It is also seen as a means to reclaim the national narrative after television itself created the monstrous and macho regime of Rodrigo Roa Duterte through the “Duterteserye” in 2016.

Teleserye at Kontemporanidad

Sa sanaysay na ito, tinutuklas ang isa kong hakà hinggil sa kalikasan ng mga teleserye o telebiswal na soap opera sa Pilipinas. Tinatawag kong “kontemporanidad,” tumutukoy ito sa katangiang mapagtukoy ng mga serye sa kontemporanyong búhay o pangyayaring panlipunan. Gámit pa rin ang pananaw na panitikan nga ang teleserye, at dahil nga rito ay nagsusulong ng tinatawag na “simbolikong aksiyon,” ipinagpapalagay na mabisang kasangkapan ang teleserye sa pagpapamalay hinggil sa lagay-panlipunan. Itatanghal ko ang ganitong mga pagpapalagay sa tinaguriang “pagbásang paloob” sa isang tampok na teleserye, ang Wildflower. Itinuturing ang pamamaraang ito ng may-akda na lalong politisasyon ng pagbása sa teleserye, na masusing pinagtatalab ang anyo at ang kontekstong inuusbungan nito

A considerable fraction of soil-respired CO2 is not emitted directly to the atmosphere

However, a non-negligible fraction of Rsoil can be consumed in the subsurface due to a host of disparate, yet simultaneous processes. The ratio between CO2 efflux/O2 influx, known as the apparent respiratory quotient (ARQ), enables new insights into CO2 losses from Rsoil not previously captured by Fsoil. We present the first study using continuous ARQ estimates to evaluate annual CO2 losses of carbon produced from Rsoil. We found that up to 1/3 of Rsoil was emitted directly to the atmosphere, whereas 2/3 of Rsoil was removed by subsurface processes. These subsurface losses are attributable to dissolution in water, biological activities and chemical reactions. Having better estimates of Rsoil is key to understanding the true influence of ecosystem production on Rsoil, as well as the role of soil CO2 production in other connected processes within the critical zoneThis project and data were supported by NSF awards 1417101 and 1331408, as well as by the European Commission project DIESEL (FP7-PEOPLE-2013-IOF, 625988) and the Spanish Ministry of Economy and Competitiveness (IJCI-2016-30822)

Kerker Conditions Upon Lossless, Absorption, and Optical Gain Regimes

The directionality and polarization of light show peculiar properties when the scattering by a dielectric sphere can be described exclusively by electric and magnetic dipolar modes. Particularly, when these modes oscillate in-phase with equal amplitude, at the so-called first Kerker condition, the zero optical backscattering condition emerges for non-dissipating spheres. However, the role of absorption and optical gain in the first Kerker condition remains unexplored. In this work, we demonstrate that either absorption or optical gain precludes the first Kerker condition and, hence, the absence of backscattered radiation light, regardless of the size of the particle, incident wavelength, and incoming polarization. Finally, we derive the necessary prerequisites of the second Kerker condition of the zero forward light scattering, finding that optical gain is a compulsory requirement

Different toxic effects of YTX in tumor K-562 and lymphoblastoid cell lines

Yessotoxin (YTX) modulates cellular phosphodiesterases (PDEs). In this regard, opposite effects had been described in the tumor model K-562 cell line and fresh human lymphocytes in terms of cell viability, cyclic adenosine 3´,5´-cyclic monophosphate (cAMP) production and protein expression after YTX treatment. Studies in depth of the pathways activated by YTX in K-562 cell line, have demonstrated the activation of two different cell death types, apoptosis and autophagy after 24 and 48 hours of treatment, respectively. Furthermore, the key role of type 4A PDE (PDE4A) in both pathways activated by YTX was demonstrated. Therefore, taking into account the differences between cellular lines and fresh cells, a study of cell death pathways activated by YTX in a non-tumor cell line with mitotic activity, was performed. The cellular model used was the lymphoblastoid cell line that represents a non-tumor model with normal apoptotic and mitotic machinery. In this context, cell viability and cell proliferation, expression of proteins involved in cell death activated by YTX and mitochondrial mass, were studied after the incubation with the toxin. Opposite to the tumor model, no cell death activation was observed in lymphoblastoid cell line in the presence of YTX. In this sense, variations in apoptosis hallmarks were not detected in the lymphoblastoid cell line after YTX incubation, whereas this type I of programmed cell death was observed in K-526 cells. On the other hand, autophagy cell death was triggered in this cellular line, while other autophagic process is suggested in lymphoblastoid cells. These YTX effects are related to PDE4A in both cellular lines. In addition, while cell death is triggered in K-526 cells after YTX treatment, in lymphoblastoid cells the toxin stops cellular proliferation. These results point to YTX as a specific toxic compound of tumor cells, since in the non-tumor lymphoblastoid cell line, no cell death hallmarks are observed

Digital image correlation after focused ion beam micro-slit drilling: A new technique for measuring residual stresses in hardmetal components at local scale

A new method has been developed for measuring residual stresses at the surface of hardmetal components with higher spatial resolution than standard X-ray diffraction methods. It is based on measuring the surface displacements produced when stresses are partially released by machining a thin slit perpendicularly to the tested surface. Slit machining is carried out by focused ion beam (FIB). Measurement of the displacement fields around the FIB slit are performed by applying an advanced digital image correlation algorithm based on Fourier analysis with sub-pixel resolution. This method compares SEM images of the same area of the hardmetal surface before and after slitting. The method has been successfully applied to as-ground and femto-laser textured surfaces showing good correlation with the standard sin2 ψ XRD technique. It is concluded that texturing induced by laser pulses in the femtoseconds regime is not perfectly adiabatic, since residual stresses are reduced by 15
