Previous studies have shown that the use of a static or dynamic mode of presenting a non-verbal series (a sequence of strokes that make up a broken line, like an open polygonal chain), as well as varying the retention time of this information in working memory, can affect the accuracy and temporal characteristics of the sequence reproduction. The present study aims to investigate the effects of the presentation mode and the retention time on the memorization and reproduction of a sequence of verbal items. For this purpose, adult subjects were asked to memorize and reproduce sequences of letters and digits which were visually presented either simultaneously (statically) or sequentially (dynamically). The response delay time (500 or 3000 ms) and the length of the sequences (from 3 to 5 elements) were varied. As dependent variables, the accuracy of stimulus reproduction and the reaction time were computed. It turned out that the memorization of verbal sequences depended on the presentation mode (static or dynamic), and the static mode seemed to lead to a more complete representation of the memorized sequences. It was shown that the sequences of letters and digits are memorized differently. It is assumed that, unlike sequences of letters, sequences of digits are stored in working memory not as a sequence of individual elements but as shorter sequences of larger chunks or even as a whole. In contrast to the situation of reproducing a broken line, in the case of reproducing verbal sequences, no significant change in the reaction time was revealed when the time of information retention in working memory was varied

Background. The mechanisms of serial information retention in working memory (WM) in children are an important and debated topic. It is related to both general theoretical ideas about memory and practical issues of learning organization. Despite numerous studies of WM regarding the retention of verbal and non-verbal sequences as well as differently presented sequences (as static or dynamic objects), there are virtually no studies that consider both the factor of modality and the way of sequence presentation. Objective. The aim of the study is to conduct a comparative analysis of delayed reproduction of verbal and non-verbal sequences by children aged 9–11 years. Study Participants. Typically developing children (n = 19, mean age 10.75±0.57) Methods. Subjects were asked to remember and recall the sequences of letters, digits, and segments that formed a broken curve. In the experiment, we varied length, retention time, and presentation mode (static or dynamic). Accuracy and reaction time were analyzed. Results. Analysis of accuracy showed that numerical sequences were best remembered, and letter sequences were worst remembered, static information was remembered better than dynamic, accuracy decreased with time and with increasing length of a sequence. Also, the analysis revealed dependence of accuracy of broken curve reproduction on the presentation mode and retention time, but these factors showed no effect on the reproduction of verbal sequences. Reaction time significantly decreased with increasing retention time for nonverbal sequences. Conclusion. Verbal and nonverbal sequences presented statically and dynamically are stored differently in children's WM. Apparently, verbal stimuli are remembered as a sequence in any presentation mode, while numerical sequences can be stored as multidigit numbers, and nonverbal sequences as a single object when presented statically and as a sequence when presented dynamically. During the retention of sequences in WM, the representations of non-verbal information are more mutable than the representations of verbal information.

In this work we estimated differences in the structure of brain systems that ensure encoding and retention in working memory (WM) of two types of information: verbal (letters) and non-verbal (segments of an open broken line) sequences presented either statically or dynamically. Brain systems were characterized by the strength of functional and effective connections between eight approximately bilaterally symmetrical cortical loci, including the dorsolateral prefrontal cortex (dlPFC) and regions of the temporal (STG), parietal (IPS), and occipital (v2) cortices. Using an 8-channel vector autoregressive model in the space of cortical EEG sources, it was shown in a group of subjects in whom high-density EEG was recorded that: (1) the brain organization of the WM when holding a sequence of letters differs from that when holding a sequence of broken line segments; (2) the brain organization of the WM depends on the mode of presentation of sequences: the strength of the functional connection is different during dynamic and static presentation of the sequence; (3) differences in the structure of functional and effective connections are not of a pronounced frequency-selective nature and are observed in all studied EEG frequency ranges from theta (4–8 Hz) to high-frequency gamma (50–60 Hz); (4) the most reliable differences between the task of retaining a sequence of letters and the task of retaining a sequence of broken line segments are observed in the alpha and beta frequency ranges during static visual presentation of sequences in the strength of functional connectivity measured using coherence between the left hemisphere dlPFC and the right hemisphere STG, as well as in theta range between the right hemisphere dlPFC and the left visual cortex v2; (5) the most reliable difference between static and dynamic presentation modes is observed in the task of holding broken line segments in the gamma frequency range (50–60 Hz) between the dlPFC in the right hemisphere and the left visual cortex v2.

Nowadays, it is difficult to imagine a powerful algorithm of cryptography that can continue cryptanalyzing and attacking without the use of unconventional techniques. Although some of the substitution algorithms are old, such as Vigenère, Alberti, and Trithemius ciphers, they are considered powerful and cannot be broken. In this paper we produce the novelty algorithm, by using of biological computation as an unconventional search tool combined with an uninhibited analysis method is the vertical probabilistic model, that makes attacking and analyzing these ciphers possible and very easy to transform the problem from a complex to a linear one, which is a novelty achievement. The letters of the encoded message are processed in the form of segments of equal length, to report the available hardware components. Each letter codon represents a region of the memory strand, and the letters calculated for it are symbolized within the probabilistic model so that each pair has a triple encoding: the first is given as a memory strand encoding and the others are its complement in the sticker encoding; These encodings differ from one region to another. The solution space is calculated and then the parallel search process begins. Some memory complexities are excluded even though they are within the solution paths formed, because the natural language does not contain its sequences. The precision of the solution and the time consuming of access to it depend on the length of the processed text, and the precision of the solution is often inversely proportional to the speed of access to it. As an average of the time spent to reach the solution, a text with a length of 200 cipher characters needs approximately 15 minutes to give 98 % of the correct components of the specific hardware. The aim of the paper is to transform OTP substitution analysis from a NP problem to a O(n^m) problem, which makes it easier to find solutions to it easily with the available capabilities and to develop methods that are harnessed to attack difficult and powerful ciphers that differ in class and type from the OTP polyalphabetic substitution ciphers.

ABSTRACT Human papillomavirus (HPV)-specific T-cell response to the HPV type 16 (HPV16) E6 protein has been shown to be associated with successful viral clearance. The patterns of CD8 T-cell epitopes within HPV16 E6 protein were previously studied in two women with HPV16 clearance. The goal of this study was to characterize these epitopes in terms of their minimal and optimal amino acid sequences and the human leukocyte antigen (HLA) restriction molecules. The presence of the epitope-specific memory T cells after viral clearance was also examined. In subject A, the dominant epitope was characterized to be E6 75-83 (KFYSKISEY), restricted by the HLA-B62 molecule, while that of subject B was E6 133-142 (HNIRGRWTGR), restricted by the HLA-A6801 molecule. Homologous epitopes were identified in five other high-risk HPV types for both of these epitopes, but they were not recognized by respective T-cell clone cells. An enzyme-linked immunospot assay or tetramer analysis was performed on peripheral blood mononuclear cells from blood samples collected after viral clearance but prior to isolation of the T-cell clones. The presence of epitope-specific memory T cells was demonstrated. These data suggest that HPV-specific memory T cells were generated in vivo and that they may remain in circulation many months, if not years, after viral clearance. Our findings broaden the spectrum of the CD8 T-cell epitopes of the HPV16 E6 protein. The characterization of novel T-cell epitopes and long-lasting epitope-specific memory T cells may be useful for the development of a potential epitope-based vaccine.

ABSTRACT We present a framework for modelling the star-formation histories of galaxies as a stochastic process. We define this stochastic process through a power spectrum density with a functional form of a broken power law. Star-formation histories are correlated on short time-scales, the strength of this correlation described by a power-law slope, α, and they decorrelate to resemble white noise over a time-scale that is proportional to the time-scale of the break in the power spectrum density, τbreak. We use this framework to explore the properties of the stochastic process that, we assume, gives rise to the log-normal scatter about the relationship between star-formation rate and stellar mass, the so-called galaxy star-forming main sequence. Specifically, we show how the measurements of the normalization and width (σMS) of the main sequence, measured in several passbands that probe different time-scales, give a constraint on the parameters of the underlying power spectrum density. We first derive these results analytically for a simplified case where we model observations by averaging over the recent star-formation history. We then run numerical simulations to find results for more realistic observational cases. As a proof of concept, we use observational estimates of the main sequence scatter at z ∼ 0 and M⋆ ≈ 1010 M⊙ measured in H α, UV+IR, and the u-band. The result is degenerate in the τbreak-α space, but if we assume α = 2, we measure $\tau _{\rm break}=170^{+169}_{-85}~\mathrm{Myr}$. This implies that star-formation histories of galaxies lose ‘memory’ of their previous activity on a time-scale of ∼200 Myr.

Abstract Human immunodeficiency virus type 1 (HIV-1) infection is characterized by dysfunction of HIV-1-specific T-lymphocytes. In order to suppress the virus and delay evolution to AIDS, antigen-loaded antigen-presenting cells (eg. dendritic cells (DC), B-lymphocytes) might be useful to boost and broaden HIV-1-specific T-cell responses. Monocyte-derived DC from untreated HIV-1-infected patients were electroporated with codon-optimized (“humanized”) mRNA coding for consensus HxB-2 (hHXB-2) Gag protein. These DC elicited a strong HIV-1 Gag-specific interferon (IFN)-γ response by an HLA-A2-restricted CD8+ T-cell line. Moreover, hHXB-2 gag mRNA-electroporated DC also triggered IFN-γ secretion by autologous peripheral blood mononuclear cells (PBMC), CD8+ T-cells and CD4+ T-cells from all patients tested. Similar observations were made with CD40-activated cultured autologous B-cells (from HIV-1-seropositive patients) electroporated with hHXB-2 gag mRNA. Gag mRNA-electroporated, but not mock-electroporated, DC or B-cells secreted Gag protein. Next, a novel strategy was developed, using autologous virus sequences. Proviral DNA was amplified by polymerase chain reaction (PCR) from PBMC and viral cDNA was amplified by reverse transcriptase PCR (RT-PCR) from plasma virus. Proviral and viral mRNA were then obtained by in vitro transcription of proviral DNA and plasma viral cDNA, respectively. Significant specific IFN-γ T-cell responses were induced in all patients tested by DC electroporated with patients’ autologous proviral and plasma viral mRNA, coding for Gag or Env. The stimulatory effect was seen on PBMC, CD8+ T-cells and CD4+ T-cells, demonstrating both major histocompatibility complex (MHC) class I and MHC class II antigen presentation. Moreover, a significant interleukin (IL)-2 T-cell response was induced by DC electroporated with hHxB-2 or proviral gag mRNA. Sequence analysis in 4 randomly chosen patients showed that they were infected by 4 different subtypes. In a heteroduplex mobility assay (HMA) up to 50% of the cloned amplified sequences exhibited a differential migration pattern; by sequencing a high degree of variation was demonstrated, particularly between clones derived from proviral DNA and plasma viral cDNA, with mutations in an immunodominant epitope (Gag) or mutations and deletions in non-immunodominant epitopes (Env). The stimulatory effect of autologous DC electroporated with autologous viral sequences opens a major perspective for the development of patient-specific immunotherapy for HIV-1 disease, that might be necessary to control the virus, in view of the major inter-patient and intra-patient sequence variability.

Streszczenie:

Clear Light of Day by Anita Desai is one of many novels that visibly exposes an individual’s, a family's, and a nation’s miseries surrounding India’s Partition in 1947. In course of Sharma Sunanda’s stay at Lawley Road in Old Delhi she meets in turn a number of the Das family. Using a non-linear narrative, the story can move from olden times through the present to reflect on the breakdown of society, family, and emotional experiences followed by gradual recovery. The family’s struggles with historical injustices as well as questions of personal agency and the unspoken battles that they have had to face is thus vividly portrayed in all its complexity. From loneliness and resentment, Bim has passed through acceptance and her journey represents the strength to continue. Across the novel are strewn memory, identity, and themes of postcolonial displacement: while at the same time examining gender dynamics especially in Bim’s resistance to patriarchal norms. Desai focuses on how people and families cope with struggles from the past, a way of portraying a sense of sad fatalism which runs through her best-known works. With clear, natural art and a silence that remains in the end, we can only say that Clear Light of Day is a sensitive story about forgiving others, trying to make peace in a world of conflict and overcoming adversity. This paper attempts to redress the balance by demonstrating how Anita Desai portrays the transformation of melancholy and alienation into hope within the Das family. The results of this research should be to investigate how to move from forgiving oneself and remembering past lives, or in other words, aid that stage along by which all is not done in process. We must never let our pasts limit our movements. This novel is read in the light of such things. Symbolizing rebirth, this paper seeks to suggest that Desai’s novel may be viewed as aesthetically parallel to other great poetic works in which human suffering yields transformation and renewal.

The ends of barley chromosomes hybridize in situ to the telomeric sequences of Arabidopsis thaliana. It was confirmed that the cross-hybridizing sequences in barley are found at the absolute ends of the chromosomes by exonuclease Bal31 digestion. The Bal31 experiments also indicated that telomere-like sequences do not occur in high copies at interstitial sites in barley. To determine whether healing of broken chromosomes occurred in aneuploid lines of barley containing extra chromosomes with breakages in different parts, in situ hybridization with the A. thaliana telomere on telotrisomic 4L and acrotrisomic 4L4S lines was conducted. Telosome 4L possesses breaks in the centromere and in an interstitial location in the long arm, while acrosome 4L4S possesses interstitial breaks in both long and short arms. In situ hybridization revealed the presence of telomere sequences on both broken ends of telosome 4L and acrosome 4L4S. In telosome 4L, telomere sequences were present even at the broken site of the centromere. These results show that broken ends of barley chromosomes were healed. Such healing may explain the stability of these chromosomes through many generations.Key words: telomere, centromere, telosome, acrosome, acrotrisomic, telotrisomic.

This thesis examines the connections between memory, brokenness and hope by investigating philosophical thought models, critically analysing artworks and exploring personal perspectives. It questions whether material aesthetics, spatial sensitivities and sculptural sympathies can offer insights into repairing and restoring unhopeful thought patterns after personal brokenness. The accompanying artworks, Now and Still, are perpetual artefacts verifying hopeful healing while remaining places of enduring hope. My research examines rhizomatic thought as described by Giles Deleuze and Felix Guattari, alongside the theories of Rosalind Krauss concerning shared material characteristics to investigate possible applications to human memory. I explored brokenness and hope through researching the historical repair techniques of Kintsugi and Sashiko before drawing on examples of repair in the natural and spiritual world. Sarah Sze’s Triple Point, Joseph Kosuth’s One and Three Chairs and Yayoi Kusama’s Armchair (Accumulation) are visual supports that illustrate how humans can activate memory towards hope by activating human agency. The paper includes discussions concerning the tendency in scientific research to see the brain as an isolated organ, detached from the human being’s ontology, and potential avenues of repair, namely hopeful renewal. Further, the research investigates the possibility of reconfiguring memories into alternate hopeful thought assemblages by sculpting memories, treating them as an artist would a medium. The emphasis of the research was on reassembling broken memory assemblages that needed hopeful repair. It includes an analysis of pieces by contemporary artists Junki Oki and Charlotte Bailey and references contemporary environmental works by Rachel Sussman and Janet Laurence. The accompanying artworks, Now and Still show distinct yet integrated assemblages that capture the adaptive and recursive nature of memory, hope, and brokenness.

Psychology<br>Ph.D.<br>Why are some memories easy to retrieve, while others are more difficult to access? Here, we tested whether we could bias memory replay, a process whereby newly learned information is reinforced by reinstating the neuronal patterns of activation that were present during learning, towards particular memory traces. The goal of this biasing is to strengthen some memory traces, making them more easily retrieved. To test this, participants were scanned during interleaved periods of encoding and rest. Throughout the encoding runs, participants learned triplets of images that were paired with semantically related sound cues. During two of the three rest periods, novel, irrelevant sounds were played. During one critical rest period, however, the sound cues learned in the preceding encoding period were played in an effort to preferentially increase reactivation of the associated visual images, a manipulation known as targeted memory reactivation. Representational similarity analyses were used to compare multi-voxel patterns of hippocampal activation across encoding and rest periods. Our index of reactivation was selectively enhanced for memory traces that were targeted for preferential reactivation during offline rest, both compared to information that was not targeted for preferential reactivation and compared to a baseline rest period. Importantly, this neural effect of targeted reactivation was related to the difference in delayed order memory for information that was cued versus uncued, suggesting that preferential replay may be a mechanism by which specific memory traces can be selectively strengthened for enhanced subsequent memory retrieval. We also found partial evidence of discrimination of unique temporal sequences within the hippocampus. Over time, multi-voxel patterns associated with a given triplet sequence became more dissimilar to the patterns associated with the other sequences. Furthermore, this neural marker of sequence preservation was correlated with the difference in delayed order memory for cued versus uncued triplets, signifying that the ability to reactivate particular temporal sequences within the hippocampus may be related to enhanced temporal order memory for the cued information. Taken together, these findings support the claim that awake replay can be biased towards preferential reactivation of particular memory traces and also suggest that this preferential reactivation, as well as representations of reactivated temporal sequences, can be detected within patterns of hippocampal activation.<br>Temple University--Theses

A long standing debate surrounds the issue of whether there is overlap in the cognitive processing of language and music. This thesis examined the extent to which there are similarities in the immediate serial recall (ISR) of verbal and tonal pitch sequences using the working memory model as the empirical framework. The thesis had three aims. The first was to develop an ISR task that would allow individuals of any level of musical training to report back sequences of tones and letters. The second aim was to compare letter and tone sequence recall performance under various conditions known to affect ISR for auditory-verbal materials. The third aim was to examine performance as a function of musical expertise. Nine experiments were conducted in total. The first six experiments tested, refined and validated the new ISR tone paradigm. The final three experiments compared musicians and nonmusicians letter and tone sequence recall using manipulations known to affect ISR for auditory-verbal items; phonological similarity (pitch proximity used for tone recall), articulatory suppression and irrelevant sound. Similarities across the results included comparable sequence length effects for letter and tone conditions, an effect of pitch proximity and phonological similarity for nonmusicians, and effects of articulatory suppression on recall of both sequence types for both groups. However, there were also a number of differences in tone recall compared to letter recall including a lack of recency and no effect of irrelevant sound. Therefore, a complete theoretical overlap between language and music processing in short-term memory was not supported by the evidence. The problems of equivalent testing across the language and music domain, and across populations of varying musical expertise were discussed. It was suggested that increased understanding of how cognitive resources are shared to process language and music in the brain would come from future research combining behavioural experiments with functional models and neuroimaging studies.

N. K. Jemisin‘s Broken Earth Trilogy explores the methods and effects of systemic oppression. Orogenes are historically oppressed and dehumanised by the wider society of The Stillness. In this thesis, I will be exploring the ways in which trauma experienced by orogenes is repeated through generations, as presented through Essun‘s varied and complex relationships with her children, and with the Fulcrum Guardian Schaffa. The collective trauma of orogenes is perpetuated through different direct and indirect actions in a repetitive cycle, on societal, interpersonal and familial levels. My reading will be in conversation with theories of trauma literature and cultural trauma, and will be informed by Afrofuturist cultural theory. Although science fiction and fantasy encourage the imagination, worldbuilding is inherently influenced by lived experiences. It could thus be stated that the trauma experienced by orogenes is informed by the collective trauma of African-Americans, as experienced by N. K. Jemisin. Afrofuturism is an aesthetic mode and critical lens which prioritises the imagining of a liberated future. Writing science fiction and fantasy through an Afrofuturist aesthetic mode encourages authors to explore forms of collective trauma as well as methods of healing. Jemisin creates an explicit parallel between the traumatic African-American experience and that of orogenes. Afrofuturist art disrupts linear time and addresses past and present trauma through the imagining of the future. The Broken Earth Trilogy provides a blueprint for the imagined liberation of oppressed groups. Using Afrofuturist tropes such as technology, the ―Black Genius‖ figure and alienation, Jemisin demonstrates the power of reclamation and the possibility of a self-created future for oppressed groups.

Streszczenie:

The hippocampus is a brain structure that plays a critical role in spatial and episodic memory. In rats, hippocampal cells called "place cells" fire specifically when the animal is at a particular location of the environment. Remarkably, when a rat traverses a path, the place cells fire in sequence in a very short time scale compatible with the "synaptic plasticity" processes between cells that might provide the formation of a memory trace reflecting the trajectory performed by the rat. Compatible with this hypothesis, the same sequences of cells are reactivated spontaneously during sleep (as if the rat "dreamed" of its environment) especially during transient hippocampal activity patterns called Sharp Wave- Ripples (SPW-R). These reactivations could then underlie the consolidation of the memory traces acquired during wakefulness. The purpose of this thesis is to better understand the formation and the consolidation role and mechanisms of hippocampal cell sequences. First, to study the dynamic of sequence emergence, we test the effect of an atypical backward movement of the rats using an electric model train. Our results show that during backwards movement, the same place cells than during forward movement are activated but their order in the sequence is reversed and this is not due to the activity of the entorhinal cortex input signal that encodes the direction of the head of the animal. These observations challenge the theoretical framework built around the emergence of sequences and favors the hypothesis that the hippocampus dynamically and internally adapts its activity to the experience of the animal. In a second step, we are interested in the impact of learning on sequence reactivations during SPW-Rs. Our results show that the suppression of SPW- Rs induces an increase in the number of SPW-Rs or homeostatic rebound specifically after a learning task (and not after a simple exploration). This rebound is canceled by the injection of an antagonist of the NMDA receptors known to play a role in synaptic plasticity processes. Homostatic regulation would thus be directly controlled by the establishment of memory traces during learning so that this ensures their consolidation during sleep<br>L'hippocampe est une structure cérébrale qui joue un rôle critique dans la mémoire épisodique et la mémoire spatiale. Chez le rat, des cellules hippocampiques appelées « cellules de lieu » déchargent spécifiquement lorsque l'animal se trouve à un endroit donné de l'environnement. De façon caractéristique, lorsqu'un rat parcourt une trajectoire, les cellules de lieu déchargent en séquence à une échelle de temps très courte compatible avec des processus de « plasticité synaptique » entre les cellules. Cette compression temporelle pourraient ainsi permettre la formation d'une trace mnésique de la trajectoire effectuée par le rat. Compatible avec cette hypothèse, les mêmes séquences de cellules sont réactivées de façon spontanée pendant le sommeil (comme si le rat « rêvait » de son environnement) notamment lors de patterns d'activité hippocampique transitoires appelés Sharp-Wave-Ripples (SPW-R). Ces réactivations pourraient alors sous-tendre la consolidation des traces mnésiques acquises pendant l'éveil durant le sommeil. Le but de ce travail de thèse est de mieux comprendre le rôle et les mécanismes de formation et de consolidation des séquences de cellules hippocampiques. Dans un premier temps, pour étudier la dynamique de mise en place des séquences, nous avons tester l'effet d'un déplacement atypique des rats en marche arrière à l'aide d'un train électrique. Nos résultats montrent que dans cette condition les même cellules de lieu qu'en marche avant sont activées mais leur ordre dans la séquence s'inverse et ceci n'est pas du à l'activité des signaux d'entrées du cortex entorhinal codant la direction de la tête de l'animal. Ces observations remettent en cause le cadre théorique établie autour de l'émergence des séquences et favorise l'hypothèse que l'hippocampe adapte son activité dynamiquement, et de façon interne selon l'expérience de l'animal. Dans un second temps, nous nous sommes intéressés à l'impact des processus d'apprentissage sur la réactivations des séquences pendant les SPW-Rs. Nos résultats montrent que la suppression des SPW-Rs spécifiquement après une tâche d'apprentissage (et pas suite à une simple exploration) induit une augmentation du nombre de SPW-Rs ou rebond homéostatique. Ce rebond est annulé par l'injection d'un antagoniste des récepteurs NMDA connus pour jouer un rôle dans les processus de plasticité synaptiques. Ce phénomène de régulation serait donc directement contrôlé par la mise en place des traces mnésiques pendant l'apprentissage et aurait pour but d'assurer leur consolidation pendant le sommeil

Streszczenie:

Segmentational grouping in music listening refers to the organisation of individual tones into tone groups that tend to be processed and subsequently recalled as perceptual units or chunks. Grouping of tones via this process tends to occur at natural breaks in structure of a tone sequence, so that relatively larger changes in pitch, amplitude or timing are perceived as boundaries which cue the segmentational grouping process. Segmentational grouping processes have been examined using behavioural research techniques; yet neurophysiological processes underlying the grouping process have received little attention, and are poorly understood. This study aimed to identify brain regions involved in the segmentational grouping process as cued by rhythmic information. Participants performed two auditory tasks while brain electrical activity responses were monitored using Steady-State Probe Topography (SSPT). Behavioural responses evoked in a task probing individuals' use of lengthened-duration tones to organise memory for pitch sequences indicated that longer-duration tones were used as cues to organise working memory representations of the musical patterns. Examination of dynamic SSPT responses during the encoding phase of a probe recognition task indicated that greater use of rhythmic cues to organise working memory representations was associated with activation of a network of left hemisphere frontal, temporal and parietal regions. During the lengthened tone, activation of left central and vertex regions and progressive activation of left temporal and temporoparietal regions were linked with use of the deviant status of the lengthened tone to update temporal expectations for the sequence. Excitatory responses observed in left posterior frontal and temporal regions to a tone following the lengthened tone were proposed to reflect temporal allocation of attention to this point in time, whereas sustained excitatory activation of left temporal, and temporoparietal regions reflected the role of these regions in supporting representations of the tone events in working memory. Finally, late inhibitory responses to the tone following the lengthened tone in left frontal, temporal, temporoparietal, and parietal regions were linked with the manipulation and closure of the working memory trace in association with the grouping process. Together, these findings support the activation of a network of left frontal, temporal and parietal regions underlying rhythmic grouping of pitch sequences.

Streszczenie:

Six young and six old squirrel monkeys were tested on two different short-term memory tasks. One was a two-choice problem, the other a nine-choice problem. A baseline, or one-choice, problem was also included. A video camera recorded all behaviors displayed by the monkeys during testing. Behaviors coded were turning, aggression, displacement, exploratory, huddling, orienting, locomotion, screen activities, and visual scanning. Also recorded was correct or incorrect choice and whether the animal showed evidence of seeing the cue stimulus. Old animals committed more errors during both phases of the experiment. Older animals were also more likely to engage in active behaviors, such as turning, whereas young animals were more likely to manifest less active behaviors, such as visual scanning and orienting. Young animals were also more likely to see the stimulus. A path analytic procedure was used to determine direct effects of age on performance and indirect effects mediated through behaviors manifested prior to the choice. For the two-choice problem, approximately half of the age effects on performance were attributable to indirect effects. For the nine-choice problem almost three quarters of the age effects on performance were attributable to indirect effects. These findings indicate that age differences in short-term memory performance are not direct effects of age alone. The age effect also occurs because age affects the behaviors of the monkeys and that these behaviors have a large effect on subsequent memory performance.

Streszczenie:

This volume contains the first Italian critical edition with introduction, translation and commentary of Euripides’ Iphigenia in Aulis. The tragedy, exhibited posthumously in 405 BCE, stages the first mythical segment of the Trojan War, namely the sacrifice of Iphigenia, daughter of king Agamemnon, head of the Greek army, in order to propitiate the winds that should lead the navy to Troy. A tragedy of intrigue and unveiling, in which all the characters try to oppose the sacrifice, judged to be an impiety despite its sacred essence. It is therefore a tragedy without gods, in which characters of modest moral stature move, unstable, ready to sudden changes of mind, and among whom the protagonist stands out: the girl who, having overcome the dismay for the destiny awaiting her, voluntarily moves towards death on the altar, for a flimsy patriotic ideal and with the illusion of achieving immortal glory. Since the end of the eighteenth century, the text of this tragedy, handed over to us by the manuscript tradition, has been exposed more than others to a rigorous philological criticism that has broken its unity, through considerable expunctions of entire sections and sequences of verses. The volume traces the phases of this critical work, showing its methods – and sometimes its excesses – and choosing a balance line in the constitution of the text. The overall exegesis of the tragedy, which I propose in this study, consists in the belief that, despite the exodus being spurious, the finale, in view of which the entire dramaturgy was composed, still had to contemplate Iphigenia’s salvation. In fact, if the Panhellenic ideal of defence against the barbarians is now meaningless, and if a war of destruction, to begin with, needs the death of an innocent person, then this death must be transcended and the horror of human sacrifice must dissolve. It therefore seems that, once political current events become opaque, the poet’s research tends to create situations of great patheticism in an aesthetic setting of refined beauty.

Streszczenie:

Abstract As dynamic random access memory (DRAM) chips grow in density and complexity, tightly packed word lines become increasingly susceptible to interference, potentially causing data retention failures. This study investigates a novel failure mechanism where disconnected buried channel array transistors (BCATs) create interference affecting three adjacent word lines (3row failure). Through systematic analysis of voltage, temperature, and operational sequences, we demonstrate that the pass gate effect significantly impairs dynamic data retention, leading to these 3row failures. Our findings reveal a previously unidentified defect mechanism in advanced DRAM technology and emphasize the importance of comprehensive testing protocols for detecting and characterizing emerging failure modes. This work contributes to the broader effort of improving DRAM reliability in modern computing systems.

Streszczenie:

A limit theory is developed for the least squares estimator for mildly and purely explosive autoregressions under drifting sequences of parameters with autoregressive roots ρn satisfying ρn → ρ ∈ (—∞, —1] ∪ [1, ∞) and n (|ρn| —1) → ∞. Drifting sequences of innovations and initial conditions are also considered. A standard specification of a short memory linear process for the autoregressive innovations is extended to a triangular array formulation both for the deterministic weights and for the primitive innovations of the linear process, which are allowed to be heteroskedastic L1-mixingales. The paper provides conditions that guarantee the validity of Cauchy limit distribution for the OLS estimator and standard Gaussian limit distribution for the t-statistic under this extended explosive and mildly explosive framework.
