Convergence in distribution norms in the CLT for non identical distributed random variables

description: We study the convergence in distribution norms in the Central Limit Theorem for non identical distributed random variables that is $$ \varepsilon_{n}(f):={\mathbb{E}}\Big(f\Big(\frac 1{\sqrt n}\sum_{i=1}^{n}Z_{i}\Big)\Big)-{\mathbb{E}}\big(f(G)\big)\rightarrow 0 $$ where $Z_{i}$ are centred independent random variables and $G$ is a Gaussian random variable. We also consider local developments (Edgeworth expansion). This kind of results is well understood in the case of smooth test functions $f$. If one deals with measurable and bounded test functions (convergence in total variation distance), a well known theorem due to Prohorov shows that some regularity condition for the law of the random variables $Z_{i}$, $i\in {\mathbb{N}}$, on hand is needed. Essentially, one needs that the law of $ Z_{i}$ is locally lower bounded by the Lebesgue measure (Doeblin's condition). This topic is also widely discussed in the literature. Our main contribution is to discuss convergence in distribution norms, that is to replace the test function $f$ by some derivative $\partial_{α}f$ and to obtain upper bounds for $\varepsilon_{n}(\partial_{α}f)$ in terms of the infinite norm of $f$. Some applications are also discussed: an invariance principle for the occupation time for random walks, small balls estimates and expected value of the number of roots of trigonometric polynomials with random coefficients.

description: We extend a recent approach to Deformed Special Relativity based on deformed dispersion laws, entailing modified Lorentz transformations and, at the same time, noncommutative geometry and intrinsically discrete spacetime. In so doing we obtain the explicit form of the modified Lorentz transformations for a special class of modified momentum-energy relations often found in literature and arising from elementary particle physics. Actually, our theory looks as a very simple and natural extension of special relativity to include a momentum cut-off at the Planck scale. In particular, the new Lorentz transformations do imply that for high boost speed ($V \sim c$) the deformed Lorentz factor does not diverge as in ordinary relativity, but results to be upperly bounded by a large finite value of the order of the ratio between the Planck mass and the particle mass. We also predict that a generic boost leaves unchanged Planck energy and momentum, which result invariant with respect to any reference frame.

description: Tylognathus cryptopogon
 Remarks.— Rainboth (1996) placed Tylognathus cryptopogon in the genus Henicorhynchus (see also Rainboth et al. [2012]). Roberts (1997) remarked that the holotype of T. cryptopogon is a species of Lobocheilos. Kottelat (2001) recognized T. cryptopogon as a simultaneous subjective synonym of T. melanotaenia Fowler, 1935 and gave precedence to T. melanotaenia, but later recognized Gymnostomus cryptopogon (Kottelat, 2013). Examination of the holotype of T. cryptopogon (Fig. 12) and the original figure from the description by Fowler (1935) confirms the claim of Roberts (1997). This specimen is identified as Lobocheilos rhabdoura following Ciccotto and Page (2016a).
 Material examined.— Thailand: Chao Phraya basin: ANSP 61273, 1, holotype of Tylognathus cryptopogon, 73.8 mm SL, Khao Nam Poo, October 1934.

description: Reinvestment decisions in housing are made by independent households in the free market, rather than by some authority. Although a micro level activity, households’ decisions in reinvestments often have broader implications at the macro level. Some of these implications can be observed directly in the built environment, whereas others are to be traced in the overall economy. Developing an understanding of households’ reinvestment behaviour and providing information on this issue could contribute to the monitoring of the economic system, as well as to urban decision-makers and planners in designing finer policies and tools of intervention in relation to problems of the housing stock and neighbourhood environments. The study aims to identify problems in reinvestment issues, factors in household reinvestment decisions, adjustment strategies of households, scale and types of reinvestment work, and motivation underlying the investments so as to explore macro implications of reinvestment behaviour. Current levels of investments in urban areas have increased to such significant magnitudes in Turkey that its implications for the overall economy have to be taken into account. Despite four decades of research and practice history in the world, reinvestment issues have been ignored in Turkey. The findings of this study reveal that although substantial capital and resources are engaged in reinvestment activities in Turkey, there are households who are unable or unwilling to reinvest to their dwellings, or conversely there are dwellings that are unlikely to receive reinvestments. These are the lowest income households, the rental stock, or dwellings located in the neighbourhoods of poor environmental quality, and flats in apartment blocks where common areas are not maintained. With another point of view, reinvestment decisions have implications in the depreciation of the housing stock. The findings display that in the Turkish case reinvestments in existing housing stock are significant components of housing investments, households’ reinvestment expenditures have implications in the construction sector and thereby in the overall economy, and households’ reinvestments help to adjust housing consumption with regard to the current needs and trends, and act as supply adjustment mechanisms in existing housing stock and neighbourhoods. The findings indicate a possible set of policy issues in the more efficient operation of the housing markets.

This provides an experimental test for the assumption connecting two versions of the shoving model for the non-Arrhenius temperature dependence of the relaxation time in glass formers. The two versions of the model are also tested directly and both are shown to work well for these liquids.

Impact of social network technology on university students' dynamic capabilities and creative performance in Malaysia

description: Social network technology (SNT) such as Facebook, Twitter, YouTube, and cloud computing services offers a cost-effective platform for students to access the ‘global-network brain’ and to develop dynamic capabilities that foster creativity and innovation. However, very few studies have explored this relationship in the developing world. This thesis examines the relationship between dynamic capabilities and creative performance among university students in Malaysia, a developing country with high usage of SNT and aspiration to become an innovation-driven economy. For Malaysia to move up the global innovation value chain, there needs a major transformation in the education system to nurture students’ creativity that empowers the next-generation innovative endeavors. Using key theories from creativity and knowledge management, this thesis develops an integrative theoretical framework to explore key internal dispositional traits (core self-evaluation (CSE) and intrinsic motivation (IM)) and external situational factors (facilitating conditions (FC) and social capital (SC)) as antecedents to dynamic capabilities (DC) and creative performance (CP). This thesis also examines the mediating role of SNT, namely the utilitarian use (UU) and hedonic use (HU) of SNT, on the relationship between DC and CP. Finally, the integrated research model assesses the impact of UU, HU, and CP on students’ actual benefits (AB) in terms of academic performance, social interaction, economic and entrepreneurial development. A multivariate analysis using partial least square technique (PLS-SEM) was conducted on a sample of 483 public and private university students in Malaysia. The empirical results show that FC indirectly impacts DC and CP while SC and CSE directly impact DC but indirectly influence CP. IM shows significant direct impact on both DC and CP. DC has a positive direct impact on CP. In particular, the use of SNT plays a significant partial mediating role on the relationship between DC and CP. UU is found to have positively influenced CP and contributed to AB whereas HU shows adverse impact on CP and does not contribute to AB. Interestingly, HU positively links to UU, which renders UU a ‘contextual mediator’ between HU and CP. The empirical results provide valuable insights on SNT-driven education policies and strategies that will enhance students’ creative performance and overall quality of their academic life in higher education.

description: Politeness is an essential part of a conversation. Like verbal communication, politeness in textual conversation and social media posts is also stimulating. Therefore, the automatic detection of politeness is a significant and relevant problem. The existing literature generally employs classical machine learning-based models like naive Bayes and Support Vector-based trained models for politeness prediction. This paper exploits the state-of-the-art (SOTA) transformer architecture and transfer learning for respectability prediction. The proposed model employs the strengths of context-incorporating large language models, a feed-forward neural network, and an attention mechanism for representation learning of natural language requests. The trained representation is further classified using a softmax function into polite, impolite, and neutral classes. We evaluate the presented model employing two SOTA pre-trained large language models on two benchmark datasets. Our model outperformed the two SOTA and six baseline models, including two domain-specific transformer-based models using both the BERT and RoBERTa language models. The ablation investigation shows that the exclusion of the feed-forward layer displays the highest impact on the presented model. The analysis reveals the batch size and optimization algorithms as effective parameters affecting the model performance.

description: Thin films of Amorphous indium oxide undergo a magnetic field driven superconducting to insulator quantum phase transition. In the insulating phase, the current-voltage characteristics show large current discontinuities due to overheating of electrons. We show that the onset voltage for the discontinuities vanishes as we approach the quantum critical point. As a result the insulating phase becomes unstable with respect to any applied voltage making it, at least experimentally, immeasurable. We emphasize that unlike previous reports of the absence of linear response near quantum phase transitions, in our system, the departure from equilibrium is discontinuous. Because the conditions for these discontinuities are satisfied in most insulators at low temperatures, and due to the decay of all characteristic energy scales near quantum phase transitions, we believe that this instability is general and should occur in various systems while approaching their quantum critical point. Accounting for this instability is crucial for determining the critical behavior of systems near the transition.

In particular, using the matched asymptotic expansion method, we analytically solve the null geodesics near the superradiant bound in the form of algebraic equations. For the case that the photon trajectories are limited in the equatorial plane, the shifts in the azimuthal angle and time are obtained.

Comparison of perception of PBL between extroverted and introverted medical students: a qualitative review of the literature
Creators: name: Chan, Hei Man Winson
name: Cooke, Siobhan
Publisher: name: F1000 Research Limited
Year: 2023

description: Background
 Problem-based learning (PBL) has been the mainstay of collaborative learning in medical schools across the globe. It has been observed that there is a mixed level of engagement among different students related to different personality traits, including extraversion and introversion. Hence, this review of the literature was done to define the current working definition of extroverts and introverts, to provide a current overview of the PBL process by comparing Barts and the London and the University of Hong Kong’s materials, to identify the strengths and weaknesses of extroverted and introverted students at different steps of PBL, and to identify and justify methods to support students’ learning needs concerning these two traits.

 Summary of Work
 This review used Web of Science, Education Research Complete, Scopus, and PubMed for searching relevant literature. Literature reviews and ethnographic studies are included. Personal reflections as both a facilitator and medical student are utilised to interpret evidence from the literature.

 Summary of Results
 It was found that extraversion and introversion lie on a continuum, and a working definition of extraversion describes students who are more assertive and well-spoken, while introversion describes students who are more introspective and less vocal. A proposed 8-step PBL process shows different introversion and extraversion strengths and weaknesses, respectively.

 Discussion and Conclusion
 This review argued that introversion nor extraversion should be labelled as problematic traits. We should support introverts to engage in the discussion while encouraging extroverts to listen more via the “think, pair, share” framework, removing extraversion biases in evaluation, and adapting from team-based learning processes.

 Take Home Messages
 Extraversion and introversion are student characteristics that entail different educational needs. We should consider reviewing the PBL process to allow all kinds of students to flourish.

description: Business process discovery approaches analyze event logs to create process models describing the current state of the underlying processes. Because this type of process mining is especially relevant for low-structured processes, there are approaches designed to deal with such processes by simplifying the resulting model. Such simplifications are primarily applied with metrics based on the frequency of observed behaviours. However, a high frequency of a certain behaviour is not synonymous with high relevance to the user. Consequently, this paper applies a design science research approach to develop and implement a business process discovery approach mining for user-defined categories to guarantee relevance to the respective user. This categorization approach is demonstrated in a case study that serves as the basis for an evaluation regarding its perceived usefulness in an expert survey. Although the method currently requires the user to categorize activities before simplifying, it is perceived to be useful by experts.

description: Mitochondrial networks exhibit a variety of complex behaviors, including coordinated cell-wide oscillations of energy states as well as a phase transition (depolarization) in response to oxidative stress. Since functional and structural properties are often interwinded, here we characterize the structure of mitochondrial networks in mouse embryonic fibroblasts using network tools and percolation theory. Subsequently we perturbed the system either by promoting the fusion of mitochondrial segments or by inducing mitochondrial fission. Quantitative analysis of mitochondrial clusters revealed that the structural parameters of healthy mitochondria lay in between the extremes of highly fragmented and completely fusioned networks. We confirmed our results by contrasting our emprirical findings with the predictions of a recently described computational model of mitochondrial network emergence based on fission-fusion kinetics. Altogether these results not only offer an objective methodology to parametrize the complexity of this organelle but add weight to the idea that mitochondrial networks behave as critical systems and undergo structural phase transitions.

description: We compute change in entanglement entropy for a single interval in $1+1$ dimensional sine-Gordon model perturbatively in the coupling. The sine-Gordon perturbation can be thought of as deformation of the free CFT by a primary operator with dimension $Δ$. In an independent computation we calculate holographic entanglement entropy for that interval from three dimensional bulk AdS which has a massive scalar with its mass satisfying $m^2= Δ(Δ-2)$. We show that the two results match for near-marginal perturbations upto leading order in the coupling.

description: We report for the first time the combination of inline process analytical technology and optical imaging to track and understand different cleaning mechanisms governing the cleaning process of Olanzapine. Clean-in-Place process parameters were studied through simultaneous inline process analytical technology and image analysis in a film flow apparatus. Methanol and water were compared as cleaning agents, and the effect of flow (0.5—1 L.min− 1 ) and temperature (20–40 ◦C, and 60 ◦C for water) was investigated. The cleaning process was assessed in terms of cleaning time, volumetric efficiency, surface residue and governing phenomena. Raman spectroscopy was used to prove no degradation occurred during cleaning. Temperature increase improves the efficiency even when solubility is negligible. High variability was observed when detachment behaviour is dominant, and it is then advisable to prioritize dissolution in the final clean-in-place steps to improve repeatability. Results show that the cleaning process is governed by an interplay of dissolution and mechanical shear phenomena and is more efficient when solubility is significant. The combination of in-situ process analytical technology and optical imaging analysis during process development allows for the determination of the most efficient and repeatable conditions, which in turn significantly reduces solvent usage in pharmaceutical cleaning.

description: Recent experimental signals have led to a revival of tetraquarks, the hypothetical $q^2\bar{q}^2$ hadronic states proposed by Jaffe in 1976 to explain the light scalar mesons. Mesonic structures with exotic quantum numbers have indeed been observed recently, though a controversy persists whether these are true resonances and not merely kinematical threshold enhancements, or otherwise states not of a true $q^2\bar{q}^2$ nature. Moreover, puzzling non-exotic mesons are also often claimed to have a tetraquark configuration. However, the corresponding model calculations are practically always carried out in pure and static bound-state approaches, ignoring completely the coupling to asymptotic two-meson states and unitarity, especially the dynamical effects thereof. In this short paper we argue that such static predictions of real tetraquark masses are highly unreliable and provide little evidence of the very existence of such states.

description: Spatiotemporal characterisation of the soil redox status within the capillary fringe (CF) is a challenging task. Air-filled porosities (ε), oxygen concentration (O2) and soil redox potential (EH) are interrelated soil variables within active biogeochemical domains such as the CF. We investigated the impact of water table (WT) rise and drainage in an undisturbed topsoil and subsoil sample taken from a Calcaric Gleysol for a period of 46 days. We merged 1D (EH and matric potential) and 2D (O2) systems to monitor at high spatiotemporal resolution redox dynamics within self-constructed redoxtron housings and complemented the data set by a 3D pore network characterization using X-ray microtomography (X-ray μCT). Depletion of O2 was faster in the organic matter- and clay-rich aggregated topsoil and the CF extended >10 cm above the artificial WT. The homogeneous and less-aggregated subsoil extended only 4 cm above the WT as indicated by ε–O2–EH data during saturation. After drainage, 2D O2 imaging revealed a fast aeration towards the lower depths of the topsoil, which agrees with the connected ε derived by X-ray μCT (εCT_conn) of 14.9% of the total porosity. However, small-scaled anoxic domains with O2 saturation <5% were apparent even after lowering the WT (down to 0.25 cm2 in size) for 23 days. These domains remained a nucleus for reducing soil conditions (EH < −100 mV), which made it challenging to characterise the soil redox status in the CF. In contrast, the subsoil aeration reached O2 saturation after 8 days for the complete soil volume. Values of εCT_conn around zero in the subsoil highlighted that soil aeration was independent of this parameter suggesting that other variables such as microbial activity must be considered when predicting the soil redox status from ε alone. The use of redoxtrons in combination with localised redox-measurements and image based pore space analysis resulted in a better 2D/3D characterisation of the pore system and related O2 transport properties. This allowed us to analyse the distribution and activity of microbiological niches highly associated with the spatiotemporal variable redox dynamics in soil environments.

description: In many aspects, elastomers and soft biological tissues exhibit similar mechanical properties such as a pronounced nonlinear stress–strain relation and a viscoelastic response to external loads. Consequently, many models use the same rheological framework and material functions to capture their behavior. The viscosity function is thereby often assumed to be constant and the corresponding free energy function follows that one of the long-term equilibrium response. This work questions this assumption and presents a detailed study on non-Newtonian viscosity functions for elastomers and brain tissues. The viscosity functions are paired with several commonly used free energy functions and fitted to two different types of elastomers and brain tissues in cyclic and relaxation experiments, respectively. Having identified suitable viscosity and free energy functions for the different materials, numerical aspects of viscoelasticity are addressed. From the multiplicative decomposition of the deformation gradient and ensuring a non-negative dissipation rate, four equivalent viscoelasticity formulations are derived that employ different internal variables. Using an implicit exponential map as time integration scheme, the numerical behavior of these four formulations are compared among each other and numerically robust candidates are identified. The fitting results demonstrate that non-Newtonian viscosity functions significantly enhance the fitting quality. It is shown that the choice of a viscosity function is even more important than the choice of a free energy function and the classical neo-Hooke approach is often a sufficient choice. Furthermore, the numerical investigations suggest the superiority of two of the four viscoelasticity formulations, especially when complex finite element simulations are to be conducted.

description: The interaction between photons and a single two-level atom constitutes a fundamental paradigm in quantum physics. The nonlinearity provided by the atom leads to a strong dependence of the light–matter interface on the number of photons interacting with the two-level system within its emission lifetime. This nonlinearity unveils strongly correlated quasiparticles known as photon bound states, giving rise to key physical processes such as stimulated emission and soliton propagation. Although signatures consistent with the existence of photon bound states have been measured in strongly interacting Rydberg gases, their hallmark excitation-number-dependent dispersion and propagation velocity have not yet been observed. Here we report the direct observation of a photon-number-dependent time delay in the scattering off a single artificial atom—a semiconductor quantum dot coupled to an optical cavity. By scattering a weak coherent pulse off the cavity–quantum electrodynamics system and measuring the time-dependent output power and correlation functions, we show that single photons and two- and three-photon bound states incur different time delays, becoming shorter for higher photon numbers. This reduced time delay is a fingerprint of stimulated emission, where the arrival of two photons within the lifetime of an emitter causes one photon to stimulate the emission of another.
Essays on microfinance

description: This thesis is a collection of three individual but related papers on microfinance. The first paper (Chapter 2) examines the impact of microfinance interventions using meta-analysis. Specifically, this chapter uses meta-analysis to review 25 empirical studies with a total of 595 estimates of the impact of microcredit on poverty reduction and microenterprise performance. The chapter considers four proxies for poverty and three for microenterprise performance in order to examine the impact of microcredit on poverty and microenterprise performance, while addressing issues of within- and between-study variations. The proxies for poverty include consumption/expenditure, assets, income, and income growth while those for microenterprise performance include labour supply, business profits, and revenue. Overall, results show no robust evidence of any significant impact on the performance of microenterprises. With regards to impact on poverty, there is no evidence of any strong positive impact, especially on consumption/expenditure. I do find evidence of a significant impact of microcredit on assets, which is positive; however, it is weak and thus of no practical economic relevance. Evidence also indicates a negative impact on income growth. The second paper (Chapter 3) contributes to the discourse regarding trade-offs between microfinance financial sustainability and outreach. Given that sustainability of microfinance institutions (MFIs) is crucial for the continual existence of the microfinance industry, emphasis has been placed on the sustainability of MFIs over the past few years. However, with the primary goal of the industry being the attainment of social outreach, the emphasis on sustainability has raised concerns about a potential adverse effect on outreach. Using data on 1595 MFIs in 109 countries and measurement indices created for sustainability and outreach, this chapter examines if there is a trade-off between sustainability and outreach. The evidence shows that there is a trade-off between sustainability and outreach depth but complementarity between sustainability and outreach breadth. Finally, the third paper (Chapter 4) hypothesizes a relationship between ethnic diversity and microfinance institution performance. I measure ethnic diversity using indices of ethnic, linguistic, and religious fractionalization. I find that fractionalization is associated with poorer MFI financial performance and leads to MFI mission drift. Trust and strong social networks are important mechanisms of influence; they are lower in more fractionalized countries. Other important channels include discrimination, ease of credit allocation and business start-up, and various MFI-specific mechanisms. Results are robust to several sensitivity checks.

description: The electronic structure of mono and bilayers of colloidal 2H-MoS2 nanosheets synthesized by wet-chemistry using potential-modulated absorption spectroscopy (EMAS), differential pulse voltammetry, and electrochemical gating measurements is investigated. The energetic positions of the conduction and valence band edges of the direct and indirect bandgap are reported and observe strong bandgap renormalization effects, charge screening of the exciton, as well as intrinsic n-doping of the as-synthesized material. Two distinct transitions in the spectral regime associated with the C exciton are found, which overlap into a broad signal upon filling the conduction band. In contrast to oxidation, the reduction of the nanosheets is largely reversible, enabling potential applications for reductive electrocatalysis. This work demonstrates that EMAS is a highly sensitive tool for determining the electronic structure of thin films with a few nanometer thicknesses and that colloidal chemistry affords high-quality transition metal dichalcogenide nanosheets with an electronic structure comparable to that of exfoliated samples.
