Authors: Lidiya Rachmawati  , Pratiwi Retnaningdyah  , Ali Mustofa
Published: March 2024

The use of digital media in online learning requires teachers to be more innovative in attracting students' interest. However, the limited interaction and communication causes problems in students' understanding. This will result in passive student responses in online classes if online learning activities are not accompanied by innovative learning motivation. This study aims to help teachers apply a more innovative approach through audiovisual media in films to help students understand issues and create critical thinking expressed through written works. The student response approach to audiovisual learning has achieved surprising findings. Experiential approach Student response combined with the cognitive theory of multimedia learning brings students into a critical understanding of the experiences of fictional characters that are even different from their lives. The findings indicate that students are more interactive and critical in responding to the issues in the film. The use of audiovisual media as digital literature through films is considered effective in developing knowledge, emotional experiences, and increasing students' social awareness. Although some compassionate students have difficulty expressing their emotions, most of them give a positive response in this method. The teacher stated that it took more time to prepare the material. In the interview, the teacher realized the changes in students' attitudes and communication, both verbally and in writing developed

In this open issue without a given theme, most of the articles discuss musical phenomena in a culturally Nordic context. This will probably look different in our next volume with its theme of Music and Minorities, just like the joint international symposium for which Svenskt visarkiv was the main organiser in October 2021. After two postponed dates due to the pandemic, the conference finally took place as an IRL event, albeit half of the participants still joined digitally.
Accidents, Obstacles and Opportunities
Authors: Frith Simon
Published: March 2024

In this paper I discuss two issues: the nature of live music performance and the shape of live music careers. In both cases my concern is with how musicians make choices. My argument is that such choices are not made freely but should be understood, rather, as a response to constraints and opportunities. In the first part of the essay I suggest that the interest and pleasure of a live concert lies not just in what we hear but equally in what we see: performing gestures which signify musical decision making. I consider how musicians indicate different kinds of motivation: entertainment, self-expression, formal discipline, attentive listening, the exploration of feeling. And I discuss the social and material constraints involved in the choice of musical instruments and performing colleagues. In the second part of the paper I focus on musical careers and critique analytic and common sense attempts to confine music-makers to specific genres. I argue that musical careers are essentially accidental and fluid, the result of particular local conditions and opportunities. It is from this perspective that I describe musicians as ordinary. Music-making must be understood in terms of everyday life and the musical role of such institutions as families, churches, education, the military and holidays. What makes musicians extraordinary is not who they are but what they do and how they use their opportunities. We should admire successful musicians not for their integrity but for their opportunism, a term that needs rescuing from its negative overtones.
Våld som kontroll, hämnd eller försvar
Authors: Åkesson Ingrid
Published: March 2024

This article analyses the universe of the traditional ballad from a perspective that problematizes gender power relations and masculinity. This universe is generally characterised by masculine domination, separation of male and female spheres, and manifest structures of power. Masculine violence, not least sexual violence, tends to be normative, especially in heroic ballads and ballads of chivalry, although other masculinities also exist. Feminine power is usually circumscribed, and feminine violence is accepted only under certain conditions. Several narrative motifs concerning masculinity, femininity, violence and power structures can be traced across different ballad types. The author analyses some of these motifs, and clusters of motifs, using the methods of re-reading, close reading and cross-reading. Examples are taken from the Scandinavian and English-Scottish ballad corpora.
Minority or minority?
Authors: Slobin Mark
Published: March 2024

The articles in this journal issue cover a wide range of topics stimulated by the term “minority.” When I was first invited to consider this topic by my Swedish colleagues back in the 1980s and 1990s, I observed and described “multiculturalism” as a way a nation-state could control the definition of a swelling group of newcomers from other countries who came with very un-Scandinavian backgrounds and sensibilities. The work of Owe Ronström, Dan Lundberg, Krister Malm, and others showed that the invention and design of a “minority-music” establishment, with resources and performance structures, might have little to do with what the recent arrivals themselves thought of as their own intimate music (Ronström 1993, Lundberg, Malm & Ronström 2003, Ronström & Lundberg 2021). My impression is that even codified Scandinavian “folk music,” like modern European national languages, began more as a product of the Minority than as a grassroots movement.
A Study of Elpis in Ancient Greek Literary Laments and Songs for the Dead: Hope and the Tradition of Greek Lament
Authors: Kousoulini Vasiliki
Published: March 2024

Much of current scholarship aims at reconstructing ritual lamentation based on evidence from early Greek epic and lyric poetry and fifth-century tragedy. This paper, although it is an examination of a specific human emotion, elpis, within the corpus of early and classical Greek epic, lyric, and dramatic poetry that are thought to preserve the oral traditions of the genre, takes also into consideration the inscribed ancient Greek songs for the dead; that is archaic and classical epigrams and their later counterparts encountered, mainly, in the Greek Anthology. A study of elpis, a highly culturally dependent emotion, within these contexts will allow us to have a glimpse of the hermeneutic frames provided by each poetic genre, their performative contexts, and the expectation of the audiences, as well as of the general world-view that is shared by the poetic genres in question. In other words, a study of elpis in ancient Greek laments and songs for the dead will enable us to have a slightly clearer image of the evolution and the nature of this oral genre from archaic times until the Late Antiquity.
"Patrum imagines": metamorfosi della paternità in Ovidio
Authors: Zanfardino Antonio
Published: March 2024

Partendo da un’indagine dell’importanza del motivo parentale nella propaganda augustea, il contributo intende analizzare la deformazione mitica dell’immagine paterna operata da Ovidio nelle Metamorfosi, individuando in essa una delle tante espressioni di instabilitas presenti nell’anomalo poema epico. In particolare, la rappresentazione deviante che l’autore fornisce di tre padri mitici - Febo, Dedalo e Teseo – potrebbe offrire nuovi spunti interpretativi di natura socio-antropologica per la vexata quaestio dell’augusteismo dell’opera ovidiana.
Chicas muertas Selvy Almady: przemoc ze względu na płeć doprowadzona do ekstremum
Authors: Mazurkiewicz Natalia
Published: March 2024

Reportaż Chicas Muertas argentyńskiej pisarki Selvy Almady opisuje problem kobietobójstw w Argentynie. Autorka, poprzez opowieść o trzech przypadkach nigdy nierozwiązanych morderstw Andrei, Marii Luisy i Sarity, pokazuje również inne aspekty przemocy wobec kobiet w kraju. Ponadto przedstawia funkcjonowanie systemu władzy, który poprzez swoją ignorancję, bierność i nieskuteczność, przyzwala na utrzymywanie się przemocowej struktury w kraju. Celem artykułu jest zaprezentowanie, w jaki sposób w reportażu przedstawione zostały wymiary przemocy ze względu na płeć obecne w Argentynie. Jednocześnie w pracy rozpatruje się jej społeczne oraz polityczne skutki. Ponadto analizuje się wizję społeczeństwa argentyńskiego przedstawioną w tekście – zarówno jego hierarchiczną strukturę opartą na męskiej dominacji jak i funkcjonowanie aparatu państwowego wobec omawianego problemu. Bazę teoretyczną pracy stanowią koncepcje biopolityczne (Agamben, Foucault, Giorgi) oraz teorie feministyczne skupiające się na problematyce kobietobójstw (Segato).

Autism spectrum disorder (ASD) is defined by common behavioral characteristics, raising the possibility of shared pathogenic mechanisms. Yet, vast clinical and etiological heterogeneity suggests personalized phenotypes. Surprisingly, our iPSC studies find that six individuals from two distinct ASD subtypes, idiopathic and 16p11.2 deletion, have common reductions in neural precursor cell (NPC) neurite outgrowth and migration even though whole genome sequencing demonstrates no genetic overlap between the datasets. To identify signaling differences that may contribute to these developmental defects, an unbiased phospho-(p)-proteome screen was performed. Surprisingly despite the genetic heterogeneity, hundreds of shared p-peptides were identified between autism subtypes including the mTOR pathway. mTOR signaling alterations were confirmed in all NPCs across both ASD subtypes, and mTOR modulation rescued ASD phenotypes and reproduced autism NPC-associated phenotypes in control NPCs. Thus, our studies demonstrate that genetically distinct ASD subtypes have common defects in neurite outgrowth and migration which are driven by the shared pathogenic mechanism of mTOR signaling dysregulation.
AXONAL distribution of mitochondria maintains neuronal autophagy during aging via eIF2β

Published: March 2024

Neuronal aging and neurodegenerative diseases are accompanied by proteostasis collapse, while cellular factors that trigger it are not identified. Impaired mitochondrial transport in the axon is another feature of aging and neurodegenerative diseases. Using
Drosophila
, we found that genetic depletion of axonal mitochondria causes dysregulation of protein degradation. Axons with mitochondrial depletion showed abnormal protein accumulation and autophagic defects. Lowering neuronal ATP levels by blocking glycolysis did not reduce autophagy, suggesting that autophagic defects are associated with mitochondrial distribution. We found that eIF2β was increased by the depletion of axonal mitochondria via proteome analysis. Phosphorylation of eIF2α, another subunit of eIF2, was lowered, and global translation was suppressed. Neuronal overexpression of
eIF2β
phenocopied the autophagic defects and neuronal dysfunctions, and lowering
eIF2β
expression rescued those perturbations caused by depletion of axonal mitochondria. These results indicate the mitochondria-eIF2β axis maintains proteostasis in the axon, of which disruption may underly the onset and progression of age-related neurodegenerative diseases.

Protein synthesis plays a major role in homeostasis and when dysregulated leads to various pathologies including cancer. To this end, imbalanced expression of eukaryotic translation initiation factors (eIFs) is not only a consequence but also a driver of neoplastic growth. eIF3 is the largest, multi-subunit translation initiation complex with a modular assembly, where aberrant expression of one subunit generates only partially functional subcomplexes. To comprehensively study the effects of eIF3 remodeling, we contrasted the impact of eIF3d, eIF3e or eIF3h depletion on the translatome of HeLa cells using Ribo-seq. Depletion of eIF3d or eIF3e, but not eIF3h reduced the levels of multiple components of the MAPK signaling pathway. Surprisingly, however, depletion of all three eIF3 subunits increased MAPK pathway activity. Depletion of eIF3e and partially eIF3d also increased translation of TOP mRNAs that encode mainly ribosomal proteins and other components of the translational machinery. Moreover, alterations in eIF3 subunit stoichiometry were often associated with changes in translation of mRNAs containing short uORFs, as in the case of the proto-oncogene MDM2 and the transcription factor ATF4. Collectively, perturbations in eIF3 subunit stoichiometry exert specific effect on the translatome comprising signaling and stress-related transcripts with complex 5’ UTRs that are implicated in homeostatic adaptation to stress and cancer.

Axon guidance molecules are critical for neuronal pathfinding because they regulate directionality and growth pace during nervous system development. However, the molecular mechanisms coordinating proper axonal extension and turning are poorly understood. Here, metastasis suppressor 1 (Mtss1), a membrane protrusion protein, ensured axonal extension while sensitizing axons to the Semaphorin 3E (Sema3E)-Plexin-D1 repulsive cue. Sema3E-Plexin-D1 signaling enhanced Mtss1 expression in projecting striatonigral neurons. Mtss1 localized to the neurite axonal side and regulated neurite outgrowth in cultured neurons. Mtss1 also aided Plexin-D1 trafficking to the growth cone, where it signaled a repulsive cue to Sema3E. Mtss1 ablation reduced neurite extension and growth cone collapse in cultured neurons. Mtss1-knockout mice exhibited fewer striatonigral projections and irregular axonal routes, and these defects were recapitulated in Plxnd1- or Sema3e-knockout mice. These findings demonstrate that repulsive axon guidance activates an exquisite autoregulatory program coordinating both axonal extension and steering during neuronal pathfinding.

Published: March 2024

Recent advancements in deep learning (DL) have played a crucial role in aiding experts to develop personalized healthcare services, particularly in drug response prediction (DRP) for cancer patients. The DL’s techniques contribution to this field is significant, and they have proven indispensable in the medical field. This review aims to analyze the diverse effectiveness of various DL models in making these predictions, drawing on research published from 2017 to 2023. We utilized the VOS-Viewer 1.6.18 software to create a word cloud from the titles and abstracts of the selected studies. This study offers insights into the focus areas within DL models used for drug response. The word cloud revealed a strong link between certain keywords and grouped themes, highlighting terms such as deep learning, machine learning, precision medicine, precision oncology, drug response prediction, and personalized medicine. In order to achieve an advance in DRP using DL, the researchers need to work on enhancing the models’ generalizability and interoperability. It is also crucial to develop models that not only accurately represent various architectures but also simplify these architectures, balancing the complexity with the predictive capabilities. In the future, researchers should try to combine methods that make DL models easier to understand; this will make DRP reviews more open and help doctors trust the decisions made by DL models in cancer DRP.

Published: March 2024

The present study was carried out to compare the effect of different plant based protein on the growth performance of Labeo rohita and Catla catla fingerlings. The experiment was designed as two experimental diets and one control group. Control groups contains (Mustard oil cake + Rice bran) whereas, experimental diets T1 (Soybean meal + Corn flour) and T2 (Groundnut meal + Wheat flour), both formulated by using the Pearson square method to maintain protein content of 35%.  The result showed that, the best survival and growth performances including SGR, FCR and PER was found in treatment T1(Soybean meal + Corn flour) as compared to other treatments. The findings suggested that the inclusion of Soya bean meal along with Corn flour in the diet led to superior fish growth and overall fish production compared to other plant-based feed ingredients investigated in this study. These results contributed valuable insights into optimizing plant-based diets for enhancing the growth and production efficiency of L. rohita and C. catla fingerlings during aquaculture operations.
Neuro‐adaptive sliding‐mode tracking control of robot manipulators
Authors: Topalov Andon V. , Kaynak Okyay , Aydin Gokhan
Published: July 2007

In this work, a new dynamical on‐line learning algorithm for robust model‐free neuro‐adaptive control of a class of nonlinear systems with uncertain dynamics is proposed and experimentally tested in order to evaluate its performance and practical feasibility in industrial settings. The control application studied is the trajectory tracking control task for the first three joints of an open architecture articulated robot manipulator. The control scheme makes use of variable structure systems theory and the feedback‐error‐learning concept. An inner sliding motion is established in terms of the neurocontroller parameters, aiming to lead the error in its control signal towards zero. The outer sliding motion bears on the system under control, the state tracking error vector of which is simultaneously driven towards the origin of the phase space. The existing relation between the two sliding motions is shown. Experimental results illustrate that the proposed neural‐network‐based controller possesses a remarkable learning capability to control complex dynamical systems, virtually without requiring a priori knowledge of the plant dynamics and laborious start‐up procedures.

Lipoplex‐Loaded Microbubbles for Gene Delivery: A Trojan Horse Controlled by Ultrasound
Authors: Lentacker I. , De Smedt S. C. , Demeester J. , Van Marck V. , Bracke M. , Sanders N. N.
Published: July 2007

Cationic poly(ethylene glycol)ylated (PEGylated) liposomes are one of the most important gene transfer reagents in non‐viral gene therapy. However, the low transfection efficiencies of highly PEGylated lipoplexes currently hamper their clinical use. Recently, ultrasound has been used in combination with microbubbles to enhance the uptake of genes in different cell types. However, the gene transfer efficiency still remains low in these experiments. To overcome the limitations of both techniques, we present the attachment of PEGylated lipoplexes to microbubbles via biotin–avidin–biotin linkages. Exposure of these lipoplex‐loaded microbubbles to ultrasound results in the release of unaltered lipoplexes. Furthermore, these lipoplex‐loaded microbubbles exhibit much higher transfection efficiencies than “free” PEGylated lipoplexes or naked plasmid DNA (pDNA) when combined with microbubbles and ultrasound. Interestingly, the lipoplex‐loaded microbubbles only transfect cells when exposed to ultrasound, which is promising for space‐ and time‐controlled gene transfer. Finally, this novel Trojan‐horse‐like concept can also be exploited to achieve the ultrasound‐triggered release of nanoparticles containing other therapeutic agents such as anticancer drugs.

Development of a sensitive and rapid nucleic acid assay with tetraphenyl porphyrinatoiron chloride by a resonance light scattering technique
Authors: Chen Zhanguang , Liu Jinbin , Zhu Li , Ding Weifeng , Han Yali
Published: July 2007

Based on the interaction between nucleic acids and tetraphenyl porphyrinatoiron chloride (FeTPPCl), a novel method for the determination of nucleic acids at the nanogram level has been developed. Under the optimum conditions, the weak resonance light scattering (RLS) intensity of FeTPPCl was greatly enhanced by nucleic acids and the enhanced RLS intensity was proportional to the concentration of nucleic acids in the range 0.02–2.8 µg/mL for calf thymus DNA, 0.05–3.3 µg/mL for fish sperm DNA and 0.07–4.5 µg/mL for yeast RNA. The detection limits (3σ) were 2.9 ng/mL for calf thymus DNA, 3.9 ng/mL for fish sperm DNA and 5.2 ng/mL for yeast RNA. Almost no interference could be observed from proteins, nucleosides and most of the metal ions. The proposed method showed good reliability, sensitivity, rapidity and reproducibility when applied to the determination of nucleic acids in synthetic and biochemical samples. The time savings make this method suitable for large routine analyses. Copyright © 2007 John Wiley & Sons, Ltd.
Application of the Radial Basis Neural Network to Optimization of a Micromixer
Authors: Ansari M. A. , Kim K.‐Y.
Published: July 2007

The radial basis neural network (RBNN) method has been applied to shape optimization of a staggered herringbone groove micromixer using three‐dimensional Navier‐Stokes analysis. The calculation of the variance of the mass fraction at various nodes on a plane in the channel is used to quantify the mixing. Optimization techniques based on the RBNN method are used to optimize the shape of the grooves on a single wall of the channel. Three design variables, i.e., the ratio of the groove depth to channel height, the ratio of the groove width to groove pitch, and the angle of the groove, are selected for optimization. The mixing index at the end of the patterned groove is employed as the objective function. The dependence of the objective function on the design variables is analyzed. The RBNN method is successfully applied to improve the degree of mixing with modification of the groove shape.
Reaction of Vitamin E Compounds with N‐Nitrosated Tryptophan Derivatives and Its Analytical Use
Authors: Müller Karsten , Korth Hans‐Gert , de Groot Herbert , Kirsch Michael
Published: July 2007

We recently showed that nitrosated tryptophan residues may act as endogenous nitric oxide storage compounds. Here, a novel reaction of nitrosotryptophan derivatives is described, in the form of the release of nitric oxide from N‐nitrosotryptophan derivatives initiated either by α‐tocopherol or by its water‐soluble form trolox. α‐Tocopherol and trolox were found to release stoichiometric amounts of nitric oxide from N‐acetyl‐N‐nitrosotryptophan as well as from the nitrosotryptophan residue in albumin. The reaction proceeds both in water and in lipophilic solution and reconstitutes the indole moiety of the tryptophan molecule quantitatively. During this reaction, α‐tocopherol‐ and trolox‐derived phenoxyl‐type radicals were identified as intermediates by ESR spectrometry. The chemical mechanism of the NO‐releasing process was established. Since S‐nitrosothiols do not react under the applied conditions, it is suggested that the trolox‐dependent release of nitric oxide may be utilizable for the detection of N‐nitrosotryptophan residues in biological samples. Furthermore, as N‐nitrosotryptophan derivatives do not undergo spontaneous decay in lipophilic environments, vitamin E may have the so far unrecognized function of preventing the accumulation of N‐nitrosotryptophan residues to toxic concentrations in biological systems.
