description: In this investigation, we have synthesized thermally stable cubic CsSnCl$_{3}$ perovskite nanocrystals (crystal size ~300 nm) with better surface morphology by the hot-injection technique. Excellent crystalline quality of these cubic nanocrystals was confirmed by high-resolution transmission electron microscopy imaging. The binding of organic ligands on the surface of the sample was characterized by nuclear magnetic resonance spectroscopy. The UV-visible spectroscopy ensured that CsSnCl$_{3}$ nanocrystals have a direct bandgap of ~2.98 eV which was confirmed by steady-state photoluminescence spectroscopy. The band edge positions calculated by the Mulliken electronegativity approach predicted the potential photocatalytic capability of the nanocrystals which was then experimentally confirmed by the photodegradation of RhB dye under visible and UV-visible irradiation. Our theoretical calculation by employing the generalized gradient approximation (GGA) and GGA + U methods demonstrated 90% accurate estimation of experimentally observed optical bandgap when $U_{eff}$ = 6 eV was considered. The ratio of the effective masses of the hole and electron expressed as D = $m_{h}^{*}/m_{e}^{*}$ was also calculated for $U_{eff}$ = 6 eV. Based on this theoretical calculation and experimental observation of the photocatalytic performance of CsSnCl$_{3}$ nanocrystals, we have proposed a new interpretation of the "D" value: a "D" value of either much smaller or much larger than 1 is the indication of low recombination rate of the photogenerated electron-hole pairs and the high photocatalytic efficiency of a photocatalyst. We believe that this comprehensive investigation may be helpful for the large-scale synthesis of thermally stable cubic CsSnCl$_{3}$ nanocrystals and also for a greater understanding of their potential in photocatalytic, photovoltaics and other prominent optoelectronic applications.

description: The conceptual design of solar powered unmanned aerial vehicle (UAV) with perpetual flight for surveillance of long-distance gas pipelines is very much needed. The requirement of this surveillance platform has been conceived due to terrorist attacks on gas pipelines in Baluchistan. Non-consumable and regenerative nature of the fuel used in solar powered UAV makes it an eternal plane under 24/7 energy balance. Such UAV operates as a terrestrial satellite, monitoring pipelines and transmitting real time imagery to control console. The requirement space was explored to select right specification matrix for the mission profile. The 24/7 flight endurance at 15,000 ft altitude during winter solstice is the key design constraint in addition to weight and power consumption of surveillance payload. Concept space was reconnoitred through Morphological Decomposition Matrix to select tail boom arrangement with non-retractable landing gears having multiple tractor electric propulsion units. Initial sizing is done to finalize Aspect Ratio and Wing span of baseline configuration. Detailed aerodynamic, propulsion, structural, stability, performance and cost analyses of this configuration are carried out to demonstrate conformance of all design requirements.

description: Discrete and continuous standard windowing are revisited and a a new taper is introduced, which is derived from the normal circular distribution by von Mises. Both the continuous-time and the discrete-time windows are considered, and their spectra obtained. A brief comparison with further classical window families is performed in terms of their properties in the spectral domain. These windows can be used in spectral analysis, and in particular, in the design of FIR (finite impulse response) filters as an alternative to the Kaiser window

description: Pre-trained general-purpose language models have been a dominating component in enabling real-world natural language processing (NLP) applications. However, a pre-trained model with backdoor can be a severe threat to the applications. Most existing backdoor attacks in NLP are conducted in the fine-tuning phase by introducing malicious triggers in the targeted class, thus relying greatly on the prior knowledge of the fine-tuning task. In this paper, we propose a new approach to map the inputs containing triggers directly to a predefined output representation of the pre-trained NLP models, e.g., a predefined output representation for the classification token in BERT, instead of a target label. It can thus introduce backdoor to a wide range of downstream tasks without any prior knowledge. Additionally, in light of the unique properties of triggers in NLP, we propose two new metrics to measure the performance of backdoor attacks in terms of both effectiveness and stealthiness. Our experiments with various types of triggers show that our method is widely applicable to different fine-tuning tasks (classification and named entity recognition) and to different models (such as BERT, XLNet, BART), which poses a severe threat. Furthermore, by collaborating with the popular online model repository Hugging Face, the threat brought by our method has been confirmed. Finally, we analyze the factors that may affect the attack performance and share insights on the causes of the success of our backdoor attack.

description: Conventional thermal preference prediction in buildings has limitations due to the difficulty in capturing all environmental and personal factors. New model features can improve the ability of a machine learning model to classify a person's thermal preference. The spatial context of a building can provide information to models about the windows, walls, heating and cooling sources, air diffusers, and other factors that create micro-environments that influence thermal comfort. Due to spatial heterogeneity, it is impractical to position sensors at a high enough resolution to capture all conditions. This research aims to build upon an existing vector-based spatial model, called Build2Vec, for predicting spatial-temporal occupants' indoor environmental preferences. Build2Vec utilizes the spatial data from the Building Information Model (BIM) and indoor localization in a real-world setting. This framework uses longitudinal intensive thermal comfort subjective feedback from smart watch-based ecological momentary assessments (EMA). The aggregation of these data is combined into a graph network structure (i.e., objects and relations) and used as input for a classification model to predict occupant thermal preference. The results of a test implementation show 14-28% accuracy improvement over a set of baselines that use conventional thermal preference prediction input variables.

The repetition effect in short term motor memory retrieval
Creators: name: Goodman, David
Publisher: name: University of British Columbia
Year: 2010

description: The main purpose of this study was to investigate a theory of information storage and retrieval of a simple motor task as an explanation of the repetition effect (RE) in a 2-choice reaction time task. Subsidiary problems involved 1) examining the effect of inter-trial interval (ITI) on RE, 2) examining the effect of probability (P) of occurrence of an S-R pair on the RE and, 3) examining the interacting effects of ITI and P on the RE. The experimental task was a 2-choice reaction time (RT) task where the subject had to respond as quickly as possible by depressing a response key following the onset of a stimulus light. Two types of tasks were used: 1) self-paced, in which the ITI was approximately 380 msec. and, 2) discrete, in which the ITI was approximately 1600 msec. Each subject was tested in both tasks and on all three probability conditions (P = .33, .50, .67). Sixteen students and staff of the University of British Columbia served as subjects. The results, which were somewhat tenuous due to equipment malfunctions, indicated that there was no RE in either the discrete or serial CRT task. This suggested that there were no differences in the subjects response strategies in either the discrete or serial task. The model of motor memory retrieval was not supported by this investigation.

description: Being able to positively interact and build relationships with playmates in preschool years is crucial to achieve positive adjustment. An update review and two studies on such topics were provided.
Study 1 is observational; it investigates the type of social experience in groups (N = 443) of children (N = 120) at preschool age in child-led vs. teacher-led contexts. The results revealed that in child-led contexts children were more likely to be alone, in dyads, and in small peer groups; groups were mostly characterized by same-gender playmates who engaged in joint interactions, with few social interactions with teachers. In teacher-led contexts, on the other hand, children were more likely to be involved in small, medium and large groups; groups were mostly characterized by other-gender playmates, involved in parallel interactions, with teachers playing a more active role.
The purpose of Study 2 was to describe the development of socio-emotional competence, temperamental traits and linguistic skill. It examined the role of children’s reciprocated nominations (=RNs) with peers, assessed via sociometric interview, in relation to socio-emotional competence, temperamental traits and linguistic skill. Finally, the similarity-homophily tendency was investigated. Socio-emotional competence and temperamental traits were assessed via teacher ratings, linguistic skill via test administration.
Eighty-four preschool children (M age = 62.53) were recruited within 4 preschool settings. Those children were quite representative of preschool population. The results revealed that children with higher RNs showed higher social competence (tendency), social orientation, positive emotionality, motor activity and linguistic skill. They exhibited lower anxiety-withdrawal. The results also showed that children prefer playmates with similar features: social competence, anger-aggression (tendency), social orientation, positive emotionality, inhibition to innovation, attention, motor activity (tendency) and linguistic skill.

description: Schizophrenia is a chronic, debilitating mental disorder whose pathophysiology is complex and not fully understood. Numerous studies suggest mitochondrial dysfunction may contribute to the development of schizophrenia. While mitochondrial ribosomes (mitoribosomes) are essential for proper mitochondrial functioning, their gene expression levels have not been studied yet in schizophrenia. We performed a systematic meta-analysis of the expression of 81 mitoribosomes subunits encoding genes, integrating ten brain samples datasets of patients with schizophrenia compared to healthy controls (overall 422 samples, 211 schizophrenia, and 211 controls). We also performed a meta-analysis of their expression in blood, integrating two blood sample datasets (overall 90 samples, 53 schizophrenia, and 37 controls). Multiple mitoribosomes subunits were significantly downregulated in brain samples (18 genes) and in blood samples (11 genes) of individuals with schizophrenia, where two showed significant downregulation in both brain and blood, MRPL4 and MRPS7. Our results support the accumulating evidence of impaired mitochondrial activity in schizophrenia. While further research is needed to validate mitoribosomes’ role as biomarkers, this direction has the potential to promote patients’ stratification and personalised treatment for schizophrenia.

description: Brain-derived neurotrophic factor (BDNF) levels vary in various conditions including alcohol use disorder (AUD). We aimed to identify drivers of these variations. Twelve patients with AUD were assessed at hospitalisation for alcohol withdrawal and four months later. We looked for associations between the change in serum BDNF levels and (1) length of abstinence, (2) anxiety (Hamilton Anxiety Scale) and depression (Beck-Depression Inventory), (3) one functional BDNF genotype (rs6265) and (4) methylation levels of 12 CpG sites within the BDNF gene (located in exons I, IV and IX). While abstinence remained, serum BDNF level increased. This increase correlated with the variation of methylation levels of the BDNF gene, and more specifically of exon I. We found no significant effect of length of abstinence, rs6265, depression or anxiety on serum BDNF level. Epigenetic regulation of the BDNF gene may be involved in variations of BDNF blood level associated with alcohol abstinence.

description: The outbreak of Covid-19 negatively affected mental health and increased loneliness. The subjective feeling of loneliness is influenced by genetic and social factors and has a negative impact on mental health. From March 2020 to June 2021 loneliness was investigated in N = 517 individuals using monthly acquired questionnaire data and Latent Growth Curve Analysis. Associations of social factors and polygenic risk scores (PRSs, n = 361) with class membership were investigated. Three classes (“average”, 40%; “not lonely”, 38%; “elevated loneliness”, 22%) were identified, that differ significantly regarding loneliness, mental dysfunction, and response to the lockdown phases. Individuals with a high PRS for neuroticism are more likely to belong to the “elevated loneliness” class, living with another person is a protective factor. As the “elevated loneliness” class was at the highest risk of mental dysfunction, our findings underscore the importance of identifying those individuals to implement counteractive measures.

description: Depression is among the psychiatric sequelae of COVID-19, affecting more than 20% of the convalescents. Its underlying pathophysiology remains unclear. Interleukin 6 (IL-6), a pro-inflammatory cytokine, plays a critical role in the COVID-19-associated cytokine storm, has been implicated in depressive disorders, and may thus be involved in post-COVID-19 depression. PubMed, Scopus, Embase, and Web of Science were systematically searched for relevant studies assessing peripheral IL-6 levels in convalescents who developed depression after COVID-19 vs. convalescents who did not. Five studies were included in our systematic review, and four entered the meta-analysis. The meta-analysis revealed that post-COVID people with de novo depression did not have statistically significant differences in IL-6 levels compared to those without depression (standardised mean difference (SMD) = 0.09, 95% confidence interval (CI) = −0.35, 0.54, p-value = 0.68). Although convalescents with depression did not have significantly higher IL-6 levels than convalescents without depression, the results should be interpreted considering the limited sample size and the low power of the included studies.

description: Flicker is a power quality phenomenon that applies to cycle instability of light intensity resulting from supply voltage fluctuation, which, in turn can be caused by disturbances introduced during power generation, transmission or distribution. The standard EN 61000-4-15 which has been recently adopted also by the IEEE as IEEE Standard 1453 relies on the analysis of the supply voltage which is processed according to a suitable model of the lamp – human eye – brain chain. As for the lamp, an incandescent 60 W, 230 V, 50 Hz source is assumed. As far as the human eye – brain model is concerned, it is represented by the so-called flicker curve. Such a curve was determined several years ago by statistically analyzing the results of tests where people were subjected to flicker with different combinations of magnitude and frequency. The limitations of this standard approach to flicker evaluation are essentially two. First, the provided index of annoyance Pst can be related to an actual tiredness of the human visual system only if such an incandescent lamp is used. Moreover, the implemented response to flicker is “subjective” given that it relies on the people answers about their feelings. In the last 15 years, many scientific contributions have tackled these issues by investigating the possibility to develop a novel model of the eye-brain response to flicker and overcome the strict dependence of the standard on the kind of the light source.  In this light of fact, this thesis is aimed at presenting an important contribution for a new Flickermeter. An improved visual system model using a physiological parameter that is the mean value of the pupil diameter,  has been presented, thus allowing to get a more “objective” representation of the response to flicker. The system used to both generate flicker and measure the pupil diameter has been illustrated along with all the results of several experiments performed on the volunteers. The intent has been to demonstrate that the measurement of that geometrical parameter can give reliable information about the feeling of the human visual system to light flicker.

description: The purpose of this study was to examine the effects of a 4% lean body weight dehydration with two levels of rehydration for four hours on the changes in physical work capacity and blood glucose. Further, the study examined the effects on volume STPD, V02, R.Q. and true 02 during the physical work capacity test. A total of 7 university-aged males were involved in the experiment as subjects. Each subject was tested in two experimental conditions, i.e. 50% rehydration and 100% rehydration, on two separate days. Each set of tests consisted of blood samples drawn from the finger tip, a physical work capacity test with expiratory gas collection. Six sets of tests were distributed as follows: one at 6 A.M., and one half an hour after dehydration. The four other sets were hourly separated. The rehydration consisted of intake of tomato juice given after the set of tests 2, 3, 4 and 5. The amount given was equally subdivided and depended on the experimental condition. Analysis of variance indicated significant changes ever time for all dependent variables, except V02; significant changes between level of rehydration for weight, and significant changes for the level of rehydration by time interaction for true 02 and weight. There was no significant individual simple correlation coefficient between blood glucose and physical work capacity for each experimental condition. There was a mean decrease of 30% in physical work capacity after heat dehydration and only 40% of the loss was recovered without significant difference between experimental conditions. Gas exchange was also affected. The volume STPD increased after dehydration, true 02 decreased after dehydration and a better recovery showed up in the 50% rehydration condition. The R.Q. parameter, in fact, did not indicate significant changes but there was a slight decrease after dehydration. The level of blood glucose decreased after dehydration tut there was an increase in the middle of rehydration, even with the expected increase in blood volume, from the liquid intake. This suggested a very high level of gluconeogenesis on those last hours, probably due to glucocorticoid hormone action.

description: The purpose of this study was to examine and interpret the legal decisions of the Canadian courts in litigation concerning tort liability on the part of the physical education teacher and coach in the gymnasium, on the playing field, in the community recreation classes and on athletic trips up to and including early 1975. Basically, the answers to the following questions were sought: (1) What is negligence in law and how does this apply to the Physical Education teacher? (2) If a teacher is involved in a law suit what legal defenses are open to him or her? (3) What are some of the areas in the school system which a teacher should be particularly aware of in terms of potential legal problems? The study aimed to stimulates (1) an appreciation for protecting the student in the school environment and on athletic trips (2) an understanding of the basic precepts of liability that might have an adverse or constructive effect on the school program (3) a realization that loss of professional integrity and financial loss can be painful consequences of one's liability. An attempt was made to clarify basic legal issues in the area of tort liability that concerns the physical educator in Canada, and to point out issues that the Physical Education teacher should be aware of in evaluating activities in the light of possible repercussions. Also, where major problems were discovered concerning the P.E. teacher's legal status in Canada, recommendations were made as to solutions to these problems. The research was carried out through an investigation of Canadian court cases relating to the topic of legal liability and the physical education teacher. From these cases it was possible to establish some basic legal principles concerning teacher liability in the classroom, in the gymnasium, on the playing field and on trips away from the school environment.

description: Matrix metalloproteinases (MMP) are a large family of proteinases that
remodel extracellular matrix (ECM) component. Recent data suggest a role for
MMPs in a number of renal pathophysiologies, associated with an imbalance of ECM
syntesis and degradation, which may result in an accumulation of ECM molecules
and renal fibrosis. The aim of this study is to elucidate the role of pro and activated
MMP-2 and 9 in urine and renal tissue of healty and nephropatic dogs. Renal tissue
of 8 healty dogs and either renal tissue and urine of 9 nephropatic dogs was collected
and analize using zimographic method, which is been validated in this study. Either
MMPs zimographic bands were present in almost all samples. In particular, pro and
activated MMP-9 zimographic bands were poorly represent in renal tissue of healty
dogs, whereas were very represent in nephropatic dogs. Pro and activated MMP-2
was present in either tissue of healty and nephropatic dogs. In urine of nephropatic
dogs, pro and activated MMP-9 was more evident than MMP-2, but there was not
correlaction with renal tissue levels, therefore urine levels of MMPs have poorly
usefulness in diagnostic pratice. The values of Pro and activated MMP-9 in
nephropatic dogs were significantly higher compared with normal dogs (p < 0,05),
whereas there was not statistically meaningful for Pro and activated MMP-2. In
conclusion, in this study we have validated a zimographic method for renal tissue of
dogs and we have illustrated the changes in nephropatic dogs, which may be useful
for further study.

mediana pari a 12.8x106/kg. Tre pazienti non sono valutabili per l’attecchimento a causa di rigetto
(1/3) o morte precoce (2/3). Sette pazienti sono valutabili per l’attecchimento; per questi pazienti il
tempo mediano a 500 PMN/mmc e a 20 x 109/l piastrine è stato rispettivamente di 17 e 20 giorni.
Quattro pazienti su 7 hanno svillupato una Graft versus Host Disease (GVHD) acuta di grado II-IV,
mentre soltanto 1/7 ha sviluppato una GVHD cronica. Sette pazienti su 10 trapiantati hanno
ottenuto una remissione completa successivamente al trapianto. Di questi, attualmente 2 pazienti
sono vivi in remissione completa, mentre gli altri 5 sono ricaduti e successivamente deceduti.
In conclusione, il trapianto aploidentico è una procedura fattibile ed efficace. Tale procedura è in
grado di garantire un 20% di lungo sopravviventi in un setting di pazienti a prognosi estremamente
infausta.

description: People talk with diversified styles. For one piece of speech, different talking styles exhibit significant differences in the facial and head pose movements. For example, the "excited" style usually talks with the mouth wide open, while the "solemn" style is more standardized and seldomly exhibits exaggerated motions. Due to such huge differences between different styles, it is necessary to incorporate the talking style into audio-driven talking face synthesis framework. In this paper, we propose to inject style into the talking face synthesis framework through imitating arbitrary talking style of the particular reference video. Specifically, we systematically investigate talking styles with our collected \textit{Ted-HD} dataset and construct style codes as several statistics of 3D morphable model~(3DMM) parameters. Afterwards, we devise a latent-style-fusion~(LSF) model to synthesize stylized talking faces by imitating talking styles from the style codes. We emphasize the following novel characteristics of our framework: (1) It doesn't require any annotation of the style, the talking style is learned in an unsupervised manner from talking videos in the wild. (2) It can imitate arbitrary styles from arbitrary videos, and the style codes can also be interpolated to generate new styles. Extensive experiments demonstrate that the proposed framework has the ability to synthesize more natural and expressive talking styles compared with baseline methods.

Protestantesimo ascetico, spirito del capitalismo, armonia degli interessi. Secolarizzazioni e immagini del mondo in Max Weber
Creators: name: D’Andrea, Dimitri
Publisher: name: Università degli Studi di Firenze
Year: 2014

description: The purpose of this paper is to reconstruct Weber’s genealogy of the spirit of capitalism. Weber conceives the transition from the ethics of ascetic Protestantism to the spirit of capitalism as a process of secular-ization. The analysis of the origin of the spirit of capitalism will help illustrate the plurality of paths of secularization, highlighting their different orientation and their independent origin. The emancipation of the economic ethos from the religious fundaments can not be understood without recurring to a notion like that of rival subrogation: a notion irreducible and opposite to that of secularization.

description: The outbreak of Covid-19 negatively affected mental health and elevated loneliness. The subjective feeling of loneliness is influenced by genetic and social factors and has a negative impact on mental health. From March 2020 to June 2021 loneliness was investigated in N = 517 individuals using monthly acquired questionnaire data and Latent Growth Curve Analysis. Three classes (“average”, 40%; “not lonely”, 38%; “elevated loneliness”, 22%) were identified, that differ significantly regarding loneliness, mental dysfunction, and response to the lockdown phases. Associations of social factors and polygenic risk scores (PRSs, n = 361) with class membership were investigated. Individuals with a high PRS for neuroticism are more likely to belong to the “elevated loneliness” class, living with another person is a protective factor. As the “ loneliness” class was at highest risk of mental dysfunction, our findings underscore the importance of identifying those individuals to implement counteractive measures.

description: In this present study, an advection ecological permeable dam (AEPD) based on a biofilm reactor was established to investigate pollution control performance and dissolved organic matter (DOM) bio-degradation. The AEPD achieved optimal efficiency—chemical oxygen demand, 6–53 mg/L; total nitrogen concentration, 1.47–6.89 mg/L; total phosphorus concentration, 0.53–3.93 mg/L，and increases in values for ultraviolet-visible parameters—SUVA254, from 0.392 to 0.673–1.438; E4/E6, from 1.09 to 1.11–1.26; A240–400, from 12.06 to 13.09–19.95; and A253–203, from 0.03 to 0.04-0.23. This showed that DOM degradation promoted its humification, aromatization, and unsaturation as well as increased the number of polar functional groups in the organic aromatic rings of DOM. Synchronous fluorescence and parallel factor analyses indicated that AEPD could effectively degrade tyrosine-like and tryptophan-like compounds, which showed the most significant decrease in fluorescence intensity. Additionally, AEPD displayed some stable dominant bacterial genera (e.g., Proteobacteria_unclassified, Bacteroidetes_unclassified, Gemmobacter, Pseudofulvimonas, Flavobacterium, Pseudomonas, and Nitrospira), although their relative abundance differed under variable hydraulic loading rates. This research provided further technical support for the application of AEPD in the treatment of water environment pollution.
Maximum force conjecture in Kiselev, $4$D-EGB and Barrow corrected-entropy black holes

description: The classical maximum force bound in the general relativity (GR) is defined between two black holes with touching horizons. We consider the maximum force conjecture for Kiselev solution that the black holes surrounded by quintessential matter, $w=-2/3$. We show that the maximum force bound is independent of black hole masses in this solution and we also indicate that when two black holes surrounded by static quintessence, the maximum force between them can approach to zero. In continue, we also study the maximum force bound for $4$D Einstein-Gauss-Bonnet ($4$D-EGB) black holes and we obtain that in this theory the maximum force bound exists and the force is bigger than the maximum force in GR. Finally, we consider the Barrow entropy in the framework of the entropic force theories and find that the maximum force only holds when the exponent of the corrected-entropy, namely $Δ$, goes to zero and for other ranges of $Δ$ it does not hold in which the mass dependence in the maximum force bound may cause the formation of naked singularities.

description: With the business environments no longer confined to geographical borders, the new wave of digital technologies has given organizations an enormous opportunity to bring together their distributed workforce and develop the ability to work together despite being apart (Prasad & Akhilesh, 2002). resupposing creativity to be a social process, the way that this phenomenon occurs when the configuration of the team is substantially modified will be questioned. Very little is known about the impact of interpersonal relationships in the creativity (Kurtzberg & Amabile, 2001). In order to analyse the ways in which the creative process may be developed, we ought to be taken into consideration the fact that participants are dealing with a quite an atypical situation. Firstly, in these cases socialization takes place amongst individuals belonging to a geographically dispersed workplace, where interpersonal relationships are mediated by the computer, and where trust must be developed among persons who have never met one another. Participants not only have multiple addresses and locations, but above all different nationalities, and different cultures, attitudes, thoughts, and working patterns, and languages. Therefore, the central research question of this thesis is as follows: “How does the creative process unfold in globally distributed teams?” With a qualitative approach, we used the case study of the Business Unit of Volvo 3P, an arm of Volvo Group. Throughout this research, we interviewed seven teams engaged in the development of a new product in the chassis and cab areas, for the brands Volvo and Renault Trucks, teams that were geographically distributed in Brazil, Sweden, France and India. Our research suggests that corporate values, alongside with intrinsic motivation and task which lay down the necessary foundations for the development of the creative process in GDT.
