To belong or not to belong: the Roma, state violence and the new Europe in the House of Lords

Field: Social Sciences (Social Sciences)

Issues of national sovereignty and membership in the body politic are central to many current political and legal debates surrounding ‘New Britain’ and Europe. Traditional understandings of citizenship and belonging are grounded in the ideal of a territorially limited and defined nation state. In this article, I explore a series of judicial and political decisions surrounding the fate of Roma or Gypsies, both as claimants to refugee status in Britain, or as subjects of domestic legal controls. I argue that these decisions construct this nomadic Other as a fundamental danger and challenge to the coherence of the legally protected body politic of the nation state ‘Britain’. I argue that the deconstructive excess found in the construction of the Roma as dangerous nomads, without allegiance to a fixed and geographically delimited nation state, might contain the kernel for a possible re-imagining of the basis of our understandings of citizenship and belonging.
A PANORAMIC PHOTOGRAPH USING A SERIES OF PHOTOGRAPHS TAKEN BY A REGULAR CAMERA

Field: Computer Science (Physical Sciences)

In order to obtain a panoramic photograph with a regular camera, a series of photographs which containing overlapping area of scenes are connected with each other. This method, however, is rarely conducted successfully, i. e. the images of the consecutive photographs are usually disconnected with each other. Without precise discussions, it has been said that it occurrs because of aberrations and optical distortions of lenses.Since the image of the photograph is ruled by the theory of perspective drawing, author considered two consecutive images of photograph could be connected smoothly with each other. Based on the theory of perspective drawing, this paper presents a method of finding an exact position and a direction of cutting line which allows to connect two consecutive photographs smoothly. With using this method, some panoramic photographs of existing scenes were made to prove the accuracy of the method.
Eliciting Emotions: Investigating the Use of Generative AI and Facial Muscle Activation in Children’s Emotional Recognition

Field: Computer Science (Physical Sciences)

This study explores children’s emotions through a novel approach of Generative Artificial Intelligence (GenAI) and Facial Muscle Activation (FMA). It examines GenAI’s effectiveness in creating facial images that produce genuine emotional responses in children, alongside FMA’s analysis of muscular activation during these expressions. The aim is to determine if AI can realistically generate and recognize emotions similar to human experiences. The study involves generating a database of 280 images (40 per emotion) of children expressing various emotions. For real children’s faces from public databases (DEFSS and NIMH-CHEFS), five emotions were considered: happiness, angry, fear, sadness, and neutral. In contrast, for AI-generated images, seven emotions were analyzed, including the previous five plus surprise and disgust. A feature vector is extracted from these images, indicating lengths between reference points on the face that contract or expand based on the expressed emotion. This vector is then input into an artificial neural network for emotion recognition and classification, achieving accuracies of up to 99% in certain cases. This approach offers new avenues for training and validating AI algorithms, enabling models to be trained with artificial and real-world data interchangeably. The integration of both datasets during training and validation phases enhances model performance and adaptability.
Adaptive duplicate detection using learnable string similarity measures

Field: Computer Science (Physical Sciences)

The problem of identifying approximately duplicate records in databases is an essential step for data cleaning and data integration processes. Most existing approaches have relied on generic or manually tuned distance metrics for estimating the similarity of potential duplicates. In this paper, we present a framework for improving duplicate detection using trainable measures of textual similarity. We propose to employ learnable text distance functions for each database field, and show that such measures are capable of adapting to the specific notion of similarity that is appropriate for the field’s domain. We present two learnable text similarity measures suitable for this task: an extended variant of learnable string edit distance, and a novel vector-space based measure that employs a Support Vector Machine (SVM) for training. Experimental results on a range of datasets show that our framework can improve duplicate detection accuracy over traditional techniques.
Alcohol Expectancy, Drinking Behavior, and Sexual Victimization Among Female and Male College Students

Field: Psychology (Social Sciences)

College students have high rates of heavy drinking, and this dangerous behavior is strongly linked to sexual victimization. Although research has examined risk factors for sexual assault, few studies have simultaneously studied the various pathways through which risks may affect sexual assault and how these pathways may be uniquely different among females and males. As such, the current study uses path analyses to examine whether alcohol expectancies mediate the relationship between social factors (e.g., hooking up, amount friends drink) and drinking behavior and experiencing sexual victimization, and whether drinking behavior mediates the relationship between alcohol expectancies and sexual victimization among a college sample of 704 males and females from a large Midwestern university. For both females and males, sexual victimization was positively associated with child sexual abuse, hooking up more often, and heavier drinking, whereas greater alcohol expectancies were associated with sexual victimization only for females. Several mediating pathways were found for both females and males. Gender comparisons revealed that some of the pathways to sexual victimization such as hooking up, amount friends drink, and housing type operated differently for females and males.
Lincosamide antibiotics stimulate dissociation of peptidyl-tRNA from ribosomes

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

At nonpermissive temperatures the peptidyl-tRNA hydrolase of pth(Ts) bacterial mutants is inactivated, and cells accumulate peptidyl-tRNA and die. Doses of erythromycin, lincomycin, or clindamycin that inhibited the growth of antibiotic-hypersensitive DB-11 pth+ cells accelerated the killing of DB-11 pth(Ts) cells at nonpermissive temperatures. Erythromycin and lincomycin also stimulated the accumulation of peptidyl-tRNA. Lincomycin and clindamycin stimulated peptidyl-tRNA dissociation from ribosomes.

Health Impacts of Freelancing: Physical, Mental, and Social Challenges Among Designers in Bangladesh

Field: Social Sciences (Social Sciences)

This study examines the health impacts of freelancing among designers in Bangladesh, a vital yet underexplored segment of the gig economy in developing countries. Using a mixed-methods approach, data were collected from an online survey of 55 freelance designers and semi-structured interviews with 20 participants, including freelancers, community leaders, and healthcare professionals. The findings reveal significant physical (e.g., fatigue, back pain, and sleep disturbances), mental (e.g., high stress due to client demands and financial instability), and social health challenges (e.g., isolation caused by irregular schedules and the undervaluation of freelancing). Gendered struggles were especially prominent, as female freelancers faced dual burdens of professional workloads and household responsibilities, intensifying stress and disrupting work-life balance. The psychological strain of constant digital engagement and client expectations further compounded these challenges. The study highlights the urgent need for systemic interventions, including affordable healthcare, structured peer networks, targeted training programs, and formal recognition of freelancing as a legitimate profession. By addressing these issues, this research contributes to the growing body of literature on gig work, offering actionable strategies to enhance freelancer well-being in developing economies.
Facile Biological Oxidation of Dopamine to 6-Hydroxydopamine p-Quinone in a Sequential Two-Step Process: Implications for Parkinson’s Disease

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

6-Hydroxydopamine (6-OHDA), a hydroxyl-derivative of the endogenous neurotransmitter dopamine, can selectively induce Parkinsonian symptoms in animal models. At present, most researchers consider 6-OHDA a man-made neurotoxicant, due to the lack of strong evidence for its presence and/or formation in biological systems. The present study aims to determine whether 6-OHDA can be formed under physiologically relevant conditions. Here, we report in the Fenton reaction system (containing 15 μM Fe2+, 142 μM ascorbic acid and 80 μM EDTA in 50 mM phosphate buffer, pH 7.4), dopamine can undergo facile oxidation to 6-OHDA p-quinone (a stable, oxidized form of 6-OHDA) in a sequential two-step process: the first step involves dopamine oxidation to its o-quinone (DAQ), and this process is facilitated by oxidants like transition metal ions Fe2+/3+ and Mn2+/3+; and the second step involves the further oxidization of DAQ to 6-OHDA p-quinone by hydroxyl radical or hydrogen peroxide. The chemical mechanism by which H2O2 oxidizes DAQ to 6-OHDA p-quinone likely results from the attack of H2O2-derived -OOH at the C-6 position of DAQ. We also demonstrate that while catalase abolishes 6-OHDA p-quinone formation by removing hydrogen peroxide or hydroxyl radical, glutathione and cysteine provide effective protection by forming conjugates with DAQ and 6-OHDA p-quinone. The results of this study demonstrate that 6-OHDA can be readily formed from dopamine under physiologically relevant conditions, and thus provide important tangible support for the long-held speculation that 6-OHDA is an intrinsic etiological factor in Parkinson's disease.
A Preliminary Study on the Renaturation of the MIP Fusion Potein Inclusion Bodies

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

The renaturation methods of insulin analogue——MIP( precursor of human insulin with B28-30 removed and B27 replaced by Lys) fusion protein inclusion bodies were studied in order to discuss the affect of three methods to the renaturation efficiency of MIP fusion protein inclusion bodies. The IMPACT-TWIN( Intein Mediated Purification with an Affinity Chitin-binding Tag-Two Intein) expression system was used to express MIP fusion protein in E. coli. Dialysis, dilution and size exclusion chromatography were employed in order to renature the inclusion bodies of MIP fusion protein. Then affinity purification was used to obtain the precursor of MIP protein. The renatured inclusion bodies were detected by SDS-PAGE and the concentration was detected by Bradford method. The results showed that the size exclusion chromatography was better than other two methods,and it could obtain more soluble and cleavable fusion protein. Its renaturation efficiency and cleavage efficiency were 65% and 5. 1%,respectively. The study of three methods in renaturation of MIP can provide the experimental evidence and theoretical basis for large scale preparation of MIP fusion protein.
Comparative Effect of The Inclusion of Zootechnical Additives in the Feed of Japanese Quails in Two Productive Phases

Field: Agricultural and Biological Sciences (Life Sciences)

Abstract This study aimed to evaluate the intestinal morphology, performance and financial analysis of the inclusion of additives in the feed during the productive period of 360 Japanese quails distributed in a completely randomized design in a split plot scheme in time with five treatments and eight repetitions of nine birds each. The treatments were: control, antibiotic, prebiotic, probiotic and synbiotic. The variables were: height, width and width/height ratio of the villi, crypt depth and villus/crypt ratio, feed intake, egg production, egg weight average, egg mass, feed conversion per mass and per dozen eggs and viability, internal rate of return, net present value and cost benefit. The additives in the feed increased height and width of the villi, decreased crypt depth and increased villus/ crypt ratio compared to the control. Feed intake was lower after the inclusion of antibiotics and synbiotics in the feed. Egg production and feed conversion improved after the inclusion of additives in the feed compared with the control. The reduction of feed intake was more pronounced with the addition of antibiotic and synbiotic in the final stage of the productive period of the Japanese quails. The inclusion of antibiotics and synbiotic proved to be more financially viable.
The effects of multiple obstacles on the locomotor behavior and performance of a terrestrial lizard

Field: Agricultural and Biological Sciences (Life Sciences)

Negotiation of variable terrain is important for many small terrestrial vertebrates. Variation in the running surface due to obstacles (woody debris, vegetation, rocks) can alter escape paths and running performance. The ability to navigate obstacles likely influences survivorship via predator evasion success, and other key ecological tasks (finding mates, acquiring food). Earlier work established that running posture and sprint performance are altered when organisms face an obstacle, and yet studies involving multiple obstacles are limited. Indeed, some habitats are cluttered with obstacles, while others are not. For many species, obstacle density may be important in predator escape and/or colonization potential by conspecifics. This study examines how multiple obstacles influence running behavior and locomotor posture in lizards. We predict that an increasing number of obstacles will increase the frequency of pausing and decrease sprint velocity. Furthermore, bipedal running over multiple obstacles is predicted to maintain greater mean sprint velocity compared to quadrupedal running, thereby revealing a potential advantage of bipedalism. Lizards were filmed (300 fps) running through a racetrack with zero, one, or two obstacles. Bipedal running posture over one obstacle was significantly faster than quadrupedal posture. Bipedal running trials contained fewer total strides than quadrupedal ones. But as obstacle number increased, the number of bipedal strides decreased. Increasing obstacle number led to slower and more intermittent locomotion. Bipedalism provided clear advantages for one obstacle, but was not associated with further benefits on additional obstacles. Hence, bipedalism helps mitigate obstacle negotiation, but not when numerous obstacles are encountered in succession.
Functional state of the nigrostriatal system of Krushinsky – Molodkina rats during audiogenic seizure expression

Field: Neuroscience (Life Sciences)

Neurochemical mechanisms of initiation and expression of epileptic seizures are poorly explored, and there are no published data that could demonstrate the functional state of the neuromediator systems at the initial state of seizure in the animals genetically prone to seizure. In the current work, we studied the role of extracellular signal-regulated kinase (ERK1/2) in the regulation of the nigrostriatal glutamate, GABA and dopamine neurons of Krushinsky – Molodkina rats at clonus-tonus and ataxia stages of audiogenic seizure. We demonstrated upregulation of ERK1/2 activity upon audio stimulation which was accompanied by increased activation of Synapsin I in the striatum and substantia nigra in comparison to intact Krushinsky – Molodkina rats. The observed exocytosis activation led to secretion of glutamate in the striatum and, as a result, to stimulation of seizures. However, at clonus-tonus stage in the striatum we revealed the changes that could participate in further inhibition of seizure activity, such as increased phosphorylation of tyrosine hydroxylase upon increased ERK1/2 activity followed by activation of dopamine release in the pars compacta of the substantia nigra. At the same time, enhanced D2 and increased D1 dopamine receptor contents were observed. These data revealed attenuation of direct (pro-seizure) and indirect (anti-seizure) pathways of the regulation of the substantia nigra GABA neurons. We demonstrated activation of GABA in the substantia nigra pars reticulate, which probably results in the inhibition of glutamate neurons of the thalamus and could be one of the mechanisms inhibiting seizure activity during ataxia.

Controversial Elements: Priority Disputes and the Discovery of Chemical Elements

Field: Chemistry (Physical Sciences)

There are only a limited number of chemical elements and to be credited with the discovery of a new one is therefore considered of great importance. Adding to the honour and fame is that traditionally the discoverer has the right to name the element in question. For these and other reasons, element discoveries are often followed by controversies regarding priority. While some of these are contemporary with the discovery process, others occur much later and are attempts to rewrite history. But what is a scientific discovery, more precisely, and why does it sometimes become controversial? From a scientific point of view, does it really matter who is recognised for the discovery of a new element? These are some of the questions considered in the paper, together with a few concrete cases from the history of chemistry. As shown by the recent disputes concerning the discoveries of synthetic elements at the end of the periodic system, modern priority disputes differ in some ways from the disputes of the past. On the other hand, there are also significant similarities.
A Posteriori Error Bounds for Linear Elliptic Equations of Potential Type

Field: Mathematics (Physical Sciences)

Second-order Linear elliptic partial differential equations of potential type with Dirichlet (type 1) or Neumann (type II) boundary conditions on a simply-connected two-dimensional domain are considered. Conjugate problems, that is, a pair of one type 1 and one type II problem, are introduced along with an auxiliary eppiptic system of two equations in such a way that the energies of the given problem, its conjugate problem, and the auxiliary system add to a known constant. There result two-sided bounds for the energy of the given problem and, as a consequence, a posteriori error bounds for the norm of the difference of an approximate solution and the exact solution of the problem. A method by which the amount of computation required to obtain the a posteriori error bounds can be almost halved in many cases of practical interest is given. A posteriori error bounds for approximate solutions of the auxiliary system are also given.

Human and Simian Immunodeficiency Viruses De-Regulate Early Hematopoiesis through a Novel Nef/PPAR-γ/STAT5 Signaling Pathway

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Abstract Infection of primates by HIV-1 and SIV induces multiple hematological abnormalities of central hematopoietic origin. Although these defects greatly contribute to the pathophysiology of HIV-1 infection, the molecular basis for altered BM function remains unknown. Here we show that when cynomolgus macaques were infected with SIV, the multipotent potential of their hematopoietic progenitor cells was lost, and this correlated with down regulation of STAT5A and STAT5B expression. However, forced expression of STAT5B entirely rescued the multipotent potential of the hematopoietic progenitor cells. In addition, an accessory viral protein required for efficient SIV and HIV replication and pathogenicity, “Negative factor” (Nef), was essential for &lt;SIV-mediated impairment of the multipotent potential of hematopoietic progenitors ex vivo and in vivo. This newly uncovered property of Nef was both conserved between HIV-1 and SIV strains and entirely dependent upon the presence of PPARγ in targeted cells. Further, PPARγ agonists mimicked Nef activity by inhibiting STAT5A and STAT5B expression and hampering the functionality of hematopoietic progenitors both ex vivo and in vivo. These findings have extended the role of Nef in the pathogenicity of HIV-1 and SIV and reveal a pivotal role for the PPARγ/STAT5 pathway in the regulation of early hematopoiesis. This study may provide a basis for investigating the potential therapeutic benefits of PPARγ antagonists in both patients with AIDS and individuals with hematopoietic disorders.
