Inanimate Nature. Pondering the Reproductive Daguerretype
Authors: Batchen Geoffrey 
Published: January 2023

Little has been published about reproductive daguerreotypes, a genre of photographic still life in which another picture – a drawing, an engraving, a lithograph, a painting, a printed text – is the sole referent. However, as this essay demonstrates, a study of reproductive daguerreotypes is a study of daguerreotypy itself – of its capacities and limitations as a medium, of its major figures and its diversity of commercial applications, of its many possible meanings, functions and related viewing practices. But it is also an opportunity to reflect on the place of such daguerreotypes in the larger story concerning the photographic reproduction of artworks. Reproductive daguerreotypes are distinctive in that they copy an artwork exactly but unfaithfully: they often laterally reverse the image even while rendering it small, monochrome, precious, shiny, evanescent, mobile. Most striking is the way such daguerreotypes partake of the logic of reproducibility without necessarily participating in the processes of mass production normally associated with it: as unique copies, they offer replication without multiplicity. In so doing, they complicate the orthodox account of this process promulgated by Walter Benjamin in the 1930s and repeated so many times since.
Feminism in the Time of Transformation. Piotr Piotrowski, Zofia Kulik and the Development of Feminist Art History in Poland
Authors: Jakubowska Agata 
Published: January 2023

This article is an analysis of one area of Piotr Piotrowski’s (1952–2015) activity in the 1990s – his writings on the art of Zofia Kulik and, more specifically, on its feminist dimension. I argue that although Piotrowski was never interested in women’s art in particular, not only did he practise feminist criticism during this period, but he was also a catalyst for the development of a specific form of feminist reflection that was then new in Polish art history. It focused on power relations and did not accept distancing oneself from social and political problems. I analyse it from the perspective of contemporary revisions of the development of feminist discourse after 1989 in Eastern Europe, which critically examines its embeddedness in Western ideas.
Double Index. The Self-Shadow in American Photography of the Second Half of the 20th Century
Authors: Stachura Julia 
Published: January 2023

The article focuses on the notion of the image of self-shadow in American photography in the second half of the twentieth century, understood as a shadow silhouette of the creator captured in a photograph. The two main problems that concern the author’s research are the lack of current, theoretical study on the problem of shadow in the history of photography from the perspective of art history (V. Stoichita, R. Casati, P. Cavanagh, H. Kanaan) and the lack of the definition of the phenomenon of self-shadow and its possible types in self-portraiture. The author’s proposition of a definition of self-shadow is based on selected photographs by four artists whose works touch upon the problem of shadow in the context of relations between the “self” and the “other” (Lee Friedlander), race and subjective invisibility (Shawn W. Walker), mask and the other-self (Andy Warhol), and the intimate recording of identity (Nan Goldin). In her analyses, the author discusses the problem of the hybrid ontology of the shadow, which is both visible and visual. In this understanding, the shadow not only refers to a physical body, present “here and now” but more importantly evokes a sense of presence, even when the artist’s body is absent in the picture. The double index refers to the image leaving its mark both in reality and on light-sensitive paper. The rudimentary, vitalistic relation linking the human body with its shadow is only a starting point for analyses of the complexity of its status and symbolism. The concepts framing Andy Warhol’s Polaroid are twinning, the mask, and the Jungian theory of the shadow archetype. To discuss the self-portrait of Shawn W. Walker, the author applies the literary-philosophical concept of invisibility based on writings from Black existentialists (W.E.B. Du Bois, F. Fanon, R. Ellison). The analyses of Lee Friedlander’s photograph have been based on the psychological distinction between the figures of the “self” and the “other”. The closing concepts that frame Nan Goldin’s self-portrait are the haptic thinking subject (M. Smolińska) and the notion of a diary. The critical apparatus of the study is supplemented by contemporary analyses of the myth of Narcissus, the mythical origins of the self-portrait, and the notion of the index (after R. Krauss, M. Michałowska, M.A. Doane).
Notes on continuity result for conformable diffusion equation on the sphere: The linear case
Authors: Nguyen Van Tien 
Published: January 2023

Abstract
In this article, we are interested in the linear conformable diffusion equation on the sphere. Our main goal is to establish some results on the continuity problem with respect to fractional order. The main technique is based on several evaluations on the sphere using spherical basis functions. To overcome the difficulty, we also need to use some calculations to control the generalized integrals.

Published: January 2023

Abstract
The biological deterioration of archaeological wood under oxygen-limited conditions varies due to the limited activities of microorganisms. It is essential to expand the knowledge of the degradation types and the status of archaeological monuments for selecting the proper consolidates. The physical, chemical, and anatomical properties of approximately 600–650 year old archaeological oak collected from an archaeological site in Iasi-Romania were analysed to assess the quality and to identify the degradation types. The results were compared with similar tests on recently-cut oak. X-ray photoelectron spectroscopy (XPS) revealed the presence of more lignin-related peaks in the archaeological oak, which likely reflected the degradation of the wood carbohydrates as evidenced by the decreased oxygen-to-carbon ratio C
ox/C
non-ox. The differences in cellulose crystallinity were not significant suggesting that any cellulose degradation occurred in the amorphous regions. This was also reflected in the dynamic water vapor sorption analysis where the differences in sorption isotherms and hysteresis of archaeological and recently-cut oaks were marginal. Microscopic analysis of the oak cells illustrated bacterial degradation patterns, while the field emission scanning electron microscopy (FESEM) showed the presence of erosion bacteria in the archaeological oak collected from the site with low oxygen conditions.
Unidirectional emission of GaN-on-Si microring laser and its on-chip integration

Published: January 2023

Abstract
GaN-based microring lasers grown on Si are promising candidates for compact and efficient light sources in Si-based optoelectronic integration and optical interconnect due to their small footprints, low mode volume, low power consumption, and high modulation rate. However, the high symmetry of circular microcavity leads to isotropic emission, which not only reduces the light collection efficiency, but also affects other adjacent devices during data transmission. In this study, the unidirectional lasing emission of room-temperature current-injected GaN-based microring laser was realized by coating metal Ag on the microring sidewall and integrating a direct coupled waveguide. The light was efficaciously confined in the cavity and only emitted from the waveguide, which avoided optical signal crosstalk with other adjacent devices. Furthermore, we integrated a microdisk at the other end of the waveguide as a photodetector, which could effectively detect the output power of the microring laser from the direct coupled waveguide. Therefore, a preliminary on-chip integration of GaN-based microring laser, waveguide and photodetector on Si substrate was successfully demonstrated for the first time, opening up a new way for on-chip integration and optical interconnect on a GaN-on-Si platform.
Encoding arbitrary phase profiles to 2D diffraction orders with controllable polarization states

Published: January 2023

Abstract
Generating 2D diffraction orders with uniform or tailored intensity distribution is highly desired for various applications including depth perception, parallel laser fabrication and optical tweezer. However, previous strategies lack the abilities to tailor multiple parameters of output light in different diffraction orders simultaneously. While such ability plays an important role in achieving various different functionalities parallelly. Here, we demonstrate a method for encoding arbitrary phase profiles to different diffraction orders with controllable polarization states by applying double-phase method into elaborately designed metasurface. Sixteen independent holograms that generated by GS algorithm are successfully encoded into 4 × 4 uniformly distributed diffraction orders. Hence, the predefined holographic images can be observed at the Fourier plane. Meanwhile, the corresponding polarization states of different orders are manipulated according to their Fourier coefficients. For verifying the polarization state of each holographic image, we calculate the Stokes parameter of each order from measured intensity distributions in the experiment. The proposed method provides an effective way to tailor multiple properties of output diffraction orders. Meanwhile, it may promote the realization of achieving various functionalities parallelly such as spectral-polarization imaging or phase-polarization detection and enhance the capabilities of optical communication systems.
A systematic review on environmental perspectives of monkeypox virus
Authors: Hemati Sara , Mohammadi-Moghadam Fazel 
Published: January 2023

Abstract
Monkeypox (MPX) is one of the common infections between humans and animals that caused by a virus belonging to the Orthopoxvirus genus. The Monkeypox virus (MPXV) outbreak is a global crisis triggered by environmental factors (virus, wastewater, surface, air) and amplified by the decisions of government officials and communities. The aim of this systematic review is to describe the environmental perspectives of MPXV with emphasis on risk assessment to prevent and control a new pandemic. Five online databases including Web of Science, PubMed, Scopus, Science Direct and Google Scholar were searched from 1990 to October 2022. Among 120 records, after the screening, four studies were included in the systematic review. The systematic review revealed that the possibility of MPXV transmission through wastewater, air, and the contaminated surfaces is a significant concern and its detection and destroying will play a major role in controlling the spread of the virus. Poxviruses have a high environmental stability, but are sensitive to all common chemical disinfectants. In conclusion, this study revealed that the environmental surveillance can be used as a complementary tool for detecting pathogens circulation in communities. This implies that the monitoring of environmental perspectives of MPXV can provide new awareness into virus transmission routes as well as the role of stakeholders and public health policies in MPXV risk management.
Understanding Colonial Archives: Reflections on Records from Habsburg Times in the Archives of Bosnia and Herzegovina
Authors: Kasumović Amila 
Published: January 2023

Abstract
The most important records of the Austro-Hungarian administrative history of Bosnia and Herzegovina are kept in the fonds of the Provincial Government in Sarajevo and of the Joint Ministry of Finance, Department for Bosnia and Herzegovina, in Vienna, both forming part of the collection of the Archives of Bosnia and Herzegovina in Sarajevo and together amounting to approximately 2000 shelf metres. The author looks here through the lens of “colonial archives” to assess the missed potential of the two fonds for writing the history of Bosnia and Herzegovina, pointing out that historians have hitherto used them primarily to study political history and a few segments of socio-economic history, neglecting recent approaches to re-establishing archives’ value for research. Yet, as the author shows, the so-called “archival turn” would prove to be an asset in deepening the understanding not only of Bosnia and Herzegovina’s Austro-Hungarian imperial history, but its history more generally.

Why Some Mice Are Smarter than Others: The Impact of Bone Morphogenetic Protein Signaling on Cognition
Authors: Bonds Jacqueline A. , Tunc-Ozcan Elif , Dunlop Sara R. , Rawat Radhika , Peng Chian-Yu , Kessler John A. 
Published: January 2023

AbstractInbred mice (C57Bl/6) display wide variability in performance on hippocampal-dependent cognitive tasks. Examination of microdissected dentate gyrus (DG) after cognitive testing showed a highly significant negative correlation between levels of bone morphogenetic protein (BMP) signaling and recognition memory. Cognitive performance decline during the aging process, and the degree of cognitive decline is strongly correlated with aging-related increases in BMP signaling. Further, cognitive performance was impaired when the BMP inhibitor, noggin, was knocked down in the DG. Infusion of noggin into the lateral ventricles enhanced DG-dependent cognition while BMP4 infusion led to significant impairments. Embryonic overexpression of noggin resulted in lifelong enhancement of recognition and spatial memory while overexpression of BMP4 resulted in lifelong impairment, substantiating the importance of differences in BMP signaling in wild-type mice. These findings indicate that performance in DG-dependent cognitive tasks is largely determined by differences in levels BMP signaling in the dentate gyrus.
Water-Reaching Platform for Longitudinal Assessment of Cortical Activity and Fine Motor Coordination Defects in a Huntington Disease Mouse Model
Authors: Wang Yundi , Sepers Marja D. , Xiao Dongsheng , Raymond Lynn A. , Murphy Timothy H. 
Published: January 2023

AbstractHuntington disease (HD), caused by dominantly inherited expansions of a CAG repeat results in characteristic motor dysfunction. Although gross motor defects have been extensively characterized in multiple HD mouse models using tasks such as rotarod and beam walking, less is known about forelimb deficits. We develop a high-throughput alternating reward/nonreward water-reaching task and training protocol conducted daily over approximately two months to simultaneously monitor forelimb impairment and mesoscale cortical changes in GCaMP activity, comparing female zQ175 (HD) and wild-type (WT) littermate mice, starting at ∼5.5 months. Behavioral analysis of the water-reaching task reveals that HD mice, despite learning the water-reaching task as proficiently as wild-type mice, take longer to learn the alternating event sequence as evident by impulsive (noncued) reaches and initially display reduced cortical activity associated with successful reaches. At this age gross motor defects determined by tapered beam assessment were not apparent. Although wild-type mice displayed no significant changes in cortical activity and reaching trajectory throughout the testing period, HD mice exhibited an increase in cortical activity, especially in the secondary motor and retrosplenial cortices, over time, as well as longer and more variable reaching trajectories by approximately seven months. HD mice also experienced a progressive reduction in successful performance. Tapered beam and rotarod tests as well as reduced DARPP-32 expression (striatal medium spiny neuron marker) after water-reaching assessment confirmed HD pathology. The water-reaching task can be used to inform on a daily basis, HD and other movement disorder onset and manifestation, therapeutic intervention windows, and test drug efficacy.

Heterogeneidad espacial y temporal de las condiciones físicas y químicas de dos lagos de inundación en la Amazonia Colombia
Authors: Torres-Bejarano Angélica M. , Duque Santiago R. , Caraballo-Gracia Pedro R. 
Published: January 2023

En la región limnética de los lagos Yahuarcaca y Zapatero, en la Amazonía colombiana, se realizaron mediciones mensuales durante un año, con el fin de evaluar así las fases limnológicas denominadas aguas altas, descenso, bajas y ascenso para las variables: profundidad máxima, temperatura, oxígeno disuelto, conductividad, sólidos totales disueltos (STD) y pH. Se encontraron diferencias significativas en las variables estudiadas durante las cuatro fases limnológicas, caracterizadas así: durante el período de inundación bajos valores de oxígeno disuelto, temperatura y alta transparencia; para aguas en ascenso, en el lago Yahuarcaca, bajos valores de pH y conductividad, y se evidenció un cambio en la dinámica hidrológica de Yahuarcaca en contraste con los resultados obtenidos en estudios previos. También fue posible inferir que el lago Zapatero tiene características limnológicas diferentes a Yahuarcaca, debido a que este último tiene una mayor conexión con el río Amazonas.

El objetivo de este estudio fue evaluar la actividad antimicrobiana del aceite esencial de Salvia officinalis L. sobre microorganismos transmitidos por alimentos con alto potencial patogénico en humanos. Para determinar su efectividad como alternativa en la conservación de alimentos se comparó con la actividad antimicrobiana de compuestos químicos utilizados ampliamente en la industria de alimentos. El aceite esencial de S. officinalis demostró un amplio espectro de inhibición microbiana sobre microorganismos Gram positivos y Gram negativos. La concentración inhibitoria mínima (CIM) estuvo entre 1 y 4 mg/ml para todas las bacterias evaluadas. Estos resultados muestran que el aceite esencial de S. officinalis puede ser utilizado para mejorar la inocuidad y tiempo de vida útil de productos alimenticios.
Divergencia morfométrica entre <i>Bothrops atrox</i> y <i>Bothrops asper</i> (Serpientes: Viperidae)
Authors: Hoyos María A. , Otero Rafael , Saldarriaga Mónica , Jaramillo Nicolás 
Published: January 2023

Se emplearon análisis morfométricos tradicionales para cuantificar las diferencias en la variación morfológica entre Bothrops atrox y Bothrops asper, cuya posición taxonómica es controversial. Para ello se examinaron doce hembras y dieciséis machos B. atrox y diecinueve hembras y once machos B. asper. Se seleccionó un conjunto de cinco distancias entre puntos anatómicos para utilizarlas en análisis de componentes principales multigrupo (ACPmg). El primer componente principal (CPmg-1) dio cuenta de la mayor porción de la variación en el nivel intragrupo y fue tomado como un estimador de tamaño. La proyección ortogonal de los individuos sobre el CPmg-1 rindió unos residuos que se consideraron representantes de la conformación biológica libre de tamaño, ya que por construcción matemática ellos son libres de alometría intragrupo. Tales residuos se emplearon en análisis discriminantes, utilizando la primera variable canónica resultante para representar la conformación libre del tamaño. Además, los análisis discriminantes permitieron evaluar la capacidad de reclasificar correctamente los individuos en sus grupos. En ambos sexos los resultados revelaron diferencias significativas de tamaño y conformación libre de tamaño entre B. atrox y B. asper. A causa de la técnica utilizada (ACPmg) se pudo asignar al componente genético de la varianza fenotípica total una porción alta de las diferencias morfométricas, lo que sugiere un nivel importante de divergencia genética entre ambas entidades biológicas. Sin embargo, la separación morfométrica no fue total, existiendo un nivel bajo pero significativo de individuos que no se pudieron asignar correctamente a sus respectivas taxa. Para llegar a conclusiones más definidas con relación a la posición taxonómica se requieren estudios con más poblaciones, utilizando herramientas analíticas adicionales como las de la morfometría geométrica.
