description: We report Very Long Baseline Array (VLBA) observations of the 1.5 GHz radio continuum emission of the {\it z=6.326} quasar SDSS J010013.02+280225.8 (hereafter J0100+2802). J0100+2802 is, by far the most optically luminous, and radio-quiet quasar with the most massive black hole known at z>6. The VLBA observations have a synthesized beam size of 12.10 mas $\times$5.36 mas (FWHM), and detected the radio continuum emission from this object with a peak surface brightness of 64.6+/-9.0 micro-Jy/beam and a total flux density of 88+/-19 micro-Jy. The position of the radio peak is consistent with that from SDSS in the optical and Chandra in the X-ray. The radio source is marginally resolved by the VLBA observations. A 2-D Gaussian fit to the image constrains the source size to $\rm (7.1+/-3.5) mas x (3.1+/-1.7) mas. This corresponds to a physical scale of (40+/-20) pc x (18+/-10) pc. We estimate the intrinsic brightness temperature of the VLBA source to be T_{B}=(1.6 +/- 1.2) x 10^{7} K. This is significantly higher than the maximum value in normal star forming galaxies, indicating an AGN origin for the radio continuum emission. However, it is also significantly lower than the brightness temperatures found in highest redshift radio-loud quasars. J0100+2802 provides a unique example to study the radio activity in optically luminous and radio quiet active galactic nuclei in the early universe. Further observations at multiple radio frequencies will accurately measure the spectral index and address the dominant radiation mechanism of the radio emission.

description: Experiments and atomic-scale simulations suggest that the transmission of plasticity carriers in deforming amorphous-crystalline nanolaminates is mediated by the biphase interface between the amorphous and crystalline layers. In this paper, we present a micromechanics model for these biphase nanolaminates that describes defect interactions through the amorphous-crystalline interface (ACI). The model is based on an effective-temperature framework to achieve a unified description of the slow, configurational atomic rearrangements in both phases when driven out of equilibrium. We show how the second law of thermodynamics constrains the density of defects and the rate of configurational rearrangements, and apply this framework to dislocations in crystalline solids and shear transformation zones (STZs) in amorphous materials. The effective-temperature formulation enables us to interpret the observed movement of dislocations to the ACI and the production of STZs at the interface as a "diffusion" of configurational disorder across the material. We demonstrate favorable agreement with experimental findings reported in (Kim et al., Adv. Funct. Mater., 2011), and demonstrate how the ACI acts as a sink of dislocations and a source of STZs.

description: Altered states of consciousness (ASC) refer to qualitative shifts in an individual's pattern of mental functioning. One such experience, autonomous sensory meridian response (ASMR), has been relatively unexplored, despite garnering significant attention online and in the media. ASMR is a pleasurable, head-orientated tingling sensation, triggered by specific audio-visual stimuli, producing feelings of relaxation, comfort and euphoria. Common triggers include whispering, soft speaking and tapping sounds. The aim of this thesis was to explore the parameters of ASMR experiences, with respect to phenomenology, prevalence, induction and relationship to personality and consciousness correlates. This was achieved through a mixed-methods approach in 4 parts. Study 1 outlined the refinement of the newly developed ASMR-15 scale, and explored the relationship of ASMR to anxiety, misophonia and absorption. Study 2 assessed the associations between Big Five personality factors and dispositional sensitivity with ASMR propensity, and the prevalence of ASMR experiences in an undergraduate student population. Study 3 outlined the successful induction of ASMR experiences in a laboratory setting, and divergence from induced frisson. Finally, Study 4 examined consciousness correlates and the possibility of ASMR existing as an anomalous experience. Taken together, the findings of these studies suggest that ASMR propensity can be measured across generalised and niche populations, and that ASMR is a relatively common, unusual experience unaccounted for by existing constructs. In addition, ASMR appears to be associated with a number of personality traits and individual differences. Lastly, the ASMR-15 appears to be a reliable and valid measure of ASMR.

description: Clinical manifestations of tuberculosis range from asymptomatic infection to a life-threatening disease such as tuberculous meningitis (TBM). Recent studies showed that the spectrum of disease severity could be related to genetic diversity among clinical strains of Mycobacterium tuberculosis (Mtb). Certain strains are reported to preferentially invade the central nervous system, thus earning the label “hypervirulent strains”.However, specific genetic mutations that accounted for enhanced mycobacterial virulence are still unknown. We previously identified a set of 17 mutations in a hypervirulent Mtb strain that was from TBM patient and exhibited significantly better intracellular survivability. These mutations were also commonly shared by a cluster of globally circulating hyper-virulent strains. Here, we aimed to validate the impact of these hypervirulent-specific mutations on the dysregulation of gene networks associated with virulence in Mtb via multi-omic analysis. We surveyed transcriptomic and proteomic differences between the hyper-virulent and low-virulent strains using RNA-sequencing and label-free quantitative LC-MS/MS approach, respectively. We identified 25 genes consistently differentially expressed between the strains at both transcript and protein level, regardless the strains were growing in a nutrient-rich or a physiologically relevant multi-stress condition (acidic pH, limited nutrients, nitrosative stress, and hypoxia). Based on integrated genomic-transcriptomic and proteomic comparisons, the hypervirulent-specific mutations in FadE5 (g. 295,746 C >T), Rv0178 (p. asp150glu), higB (p. asp30glu), and pip (IS6110-insertion) were linked to deregulated expression of the respective genes and their functionally downstream regulons. The result validated the connections between mutations, gene expression, and mycobacterial pathogenicity, and identified new possible virulence-associated pathways in Mtb.

description: The critical radius of a core-shell-type nucleus grown by diffusion in a phase-separated solution is studied. A {\it kinetic} critical radius rather than the {\it thermodynamic} critical radius of standard classical nucleation theory can be defined from the diffusional growth equations. It is shown that there exist two kinetic critical radii for the core-shell-type nucleus, for which both the inner core radius and the outer shell radius will be stationary. Therefore, these two critical radii correspond to a single critical point of the nucleation path with a single energy barrier even though the nucleation looks like a two-step process. The two radii are given by formulas similar to that of classical nucleation theory if the Ostwald-Freundlich boundary condition is imposed at the surface of the inner nucleus and that of the outer shell. The subsequent growth of a core-shell-type post-critical nucleus follows the classical picture of Ostwald's step rule. Our result is consistent with some of the experimental and numerical results which suggest the core-shell-type critical nucleus.

description: The X-ray photoelectron spectroscopy (XPS) and near-edge X-ray absorption fine structure (NEXAFS) spectroscopy of the carbon K-edge for the two nano onion-like fullerenes (NOLFs) C20@C80 isomers have been in theory performed by density functional theory (DFT) method. We have especially focussed on the structure-spectroscopy relationship by exploring in detail and analyzing systematically the calculated spectra. Both the XPS and NEXAFS spectra show dependence on molecular structures, so these two spectroscopic techniques can be used to identify the two NOLFs C20@C80 isomers. Meanwhile, the spectral components of each C20@C80 isomer based on the local environment of carbon atoms have been calculated at the same level. Furthermore, we have tested the feasibility of using the building block (BB) approach to quickly estimate the XPS and NEXAFS spectra in the NOLFs C20@C80 system. Results show that applying the BB approach is impossible to predict the direct calculated results for the NOLFs C20@C80. Additionally, fullerene C100(D2) as an isomer of C20@C80 can be distinguished from the two C20@C80 isomers by the XPS and NEXAFS spectra.

description: Cryptosporidium parvum is a leading cause of diarrhoeal illness worldwide being a significant threat to young children and immunocompromised patients, but the pathogenesis caused by this parasite remains poorly understood. C. parvum was recently linked with oncogenesis. Notably, the mechanisms of gene expression regulation are unexplored in Cryptosporidium and little is known about how the parasite impact host genome regulation. Here, we investigated potential histone lysine methylation, a dynamic epigenetic modification, during the life cycle of the parasite. We identified SET-domain containing proteins, putative lysine methyltransferases (KMTs), in the C. parvum genome and classified them phylogenetically into distinct subfamilies (namely CpSET1, CpSET2, CpSET8, CpKMTox and CpAKMT). Our structural analysis further characterized CpSET1, CpSET2 and CpSET8 as histone lysine methyltransferases (HKMTs). The expression of the CpSET genes varies considerably during the parasite life cycle and specific methyl-lysine antibodies showed dynamic changes in parasite histone methylation during development (CpSET1:H3K4; CpSET2:H3K36; CpSET8:H4K20). We investigated the impact of C. parvum infection on the host histone lysine methylation. Remarkably, parasite infection led to a considerable decrease in host H3K36me3 and H3K27me3 levels, highlighting the potential of the parasite to exploit the host epigenetic regulation to its advantage. This is the first study to describe epigenetic mechanisms occurring throughout the parasite life cycle and during the host–parasite interaction. A better understanding of histone methylation in both parasite and host genomes may highlight novel infection control strategies.

description: Cyber-crime is a large and growing issue. The problems presented by cyber-crime will not be addressed unless its true extent is known and an important factor in this is the reporting of cyber-crime events by its victims. Children are particularly vulnerable to cyber-crime due to their inexperience and the amount of time they spend on the internet, particularly playing online videogames. There has been limited attention in the literature to the reporting of cyber-crime by school aged children and the reasons why they may not choose to report an incident of cyber-crime. This research involved a group of 47 participants, aged 18 to 25. Participants were surveyed about their video game playing habits, cyber-crime experience and the reporting of those experiences while they were of school age. The age range of participants was chosen so that they would have sufficient recall of their experiences of cyber-crime while of school age but would have the emotional maturity to deal with the recall of potentially traumatic events. Frequency of experience of cyber-crime showed variation depending on the type of cyber-crime. Participants reported a low level of reporting of cyber-crime experiences, for reasons that included guilt, embarrassment and not considering the event important enough to report. Gender differences were found in the frequency of experience of cyber-crime and reporting of some categories of cyber-crime, including hacking and cyber-pornography --abstract.

description: Chiral magnets with topologically nontrivial spin order such as Skyrmions have generated enormous interest in both fundamental and applied sciences. We report broadband microwave spectroscopy performed on the insulating chiral ferrimagnet Cu$_{2}$OSeO$_{3}$. For the damping of magnetization dynamics we find a remarkably small Gilbert damping parameter of about $1\times10^{-4}$ at 5 K. This value is only a factor of 4 larger than the one reported for the best insulating ferrimagnet yttrium iron garnet. We detect a series of sharp resonances and attribute them to confined spin waves in the mm-sized samples. Considering the small damping, insulating chiral magnets turn out to be promising candidates when exploring non-collinear spin structures for high frequency applications.

description: We present results of long NuSTAR (200 ks) and XMM-Newton (100 ks) observations of the Arches stellar cluster, a source of bright thermal (kT~2 keV) X-rays with prominent Fe XXV K_alpha 6.7 keV line emission and a nearby molecular cloud, characterized by an extended non-thermal hard X-ray continuum and fluorescent Fe K_alpha 6.4 keV line of a neutral or low ionization state material around the cluster. Our analysis demonstrates that the non-thermal emission of the Arches cloud underwent a dramatic change, with its homogeneous morphology, traced by fluorescent Fe K_alpha line emission, vanishing after 2012, revealing three bright clumps. The declining trend of the cloud emission, if linearly fitted, is consistent with half-life decay time of ~8 years. Such strong variations have been observed in several other molecular clouds in the Galactic Centre, including the giant molecular cloud Sgr B2, and point toward a similar propagation of illuminating fronts, presumably induced by the past flaring activity of Sgr A*.

description: The smart grid is a user system that will elevate the conventional electrical grid system to one that functions more cooperatively, responsively and economically. One of the most important features of smart grid technology that makes it smart or smarter than the current grid is the integration of bi-directional flow of information along with electricity, which can be used to provide effective and controlled power generation and consumption. In this project, first we investigate how game theory can be used in smart grid communication due to its proven efficiency in wireless and wireline communication. And then to implement algorithms using cooperative game theory to solve the problem of the power loss during power transfer process. We have applied the game theoretic coalition formulation strategy and explain how the micro-grid action as to form coalition group to minimize the power loss when power is transmitted from a micro-grid to another micro-grid or the macro station. To maximizethe profit of coalition, a micro-grid will find partners which are able to maximize the payoff function value. In this project we focused in particular on using cooperative game theory to solve the problem of power loss.

Moreover, whenever the surface is incompressible and $\partial$-incompressible in the link exterior, it can be isotoped to have a standard tube at some crossing of any reduced alternating diagram.

description: The optimal interval before receiving SARS-COV-2 vaccination for patients who have received anti-CD 20 monoclonal antibodies remains unclear. We considered original studies up to 29 October 2022 and conducted searches in Embase,Medrxiv, PubMed, and SSRN. We excluded search results that did not match our research question’s subject. Human immune response outcomes were analysed inpatients who had previously received anti-CD20 antibody therapy. We analyzed the collected results using sensitivity curves and forest plots. Twenty-eight studies with a total of 1455 subjects receiving anti-CD20 monoclonal antibodies were included in the present analysis. The humoral immune response rates to the time between the last anti-CD20 treatment and vaccination for 3–6 months, 6 months,6–9 months, and 9–12 months were 0.23 (95% CI 0.14 to 0.36), 0.36 (95% CI 0.19 to 0.58), 0.49 (95% CI 0.35 to 0.64) and 0.64 (95% CI 0.48 to 0.77),respectively. The humoral immune response rates were.16 (95% CI 0.03 to 0.57) when B cell was 0/ul, and 0.49 (95% CI 0.38 to 0.61)when B cells were more than 5/ul. The humoral immune response rate for multiple sclerosis was 0.39 (95% CI 0.22 to 0.60) and 0.48 (95% CI 0.29 to 0.68) for B-cell non-Hodgkin lymphoma. The area underneath the curve(AUC) was 0.69 with a cut-off value of 5.5 months. The present results suggested that the optimal interval for SARS-COV-2 vaccination after the final dose of anti-CD20 monoclonal antibody was 5.5 months.

description: Legionnaires’ Disease (LD) is a severe pneumonia mainly caused in Europe by Legionella pneumophila serogroup 1 (Lp1). Sequence-based typing methods reveal that some sequence types (ST) are overrepresented in clinical samples such as ST1 and ST47, suggesting that some strains are more fit for infection than others. In the present study, a collection of 108 Lp1 clinical isolates were used to evaluate the strain-dependent immune responses from human macrophages. Clinical Lp1 isolates induced differential TNFα secretion from macrophages. ST1 isolates induced a significantly higher TNF-α secretion than non-ST1, whereas ST47 isolates induced a significantly lower TNF-α secretion than non-ST47 isolates. ST1 isolates induced a significantly higher cell death than ST47 isolates evaluated by lactate dehydrogenase activity (cytotoxicity) and caspase-3 activity (apoptosis). Treatment of macrophages with anti-TNF-α antibodies significantly reduced the cell death in macrophages infected with ST1 or ST47 strains. The TNF-α secretion was neither explained by a differential bacterial replication nor by the number or type (bystander or infected) of TNF-α producing cells following infection but by a differential response from macrophages. The Paris ST1 reference strain elicited a significantly higher TNF-α gene transcription and a higher induction of NF-κB signaling pathway than the Lorraine ST47 reference strain. Clinical Lp1 isolates induce a diverse immune response and cell death, which could be related to the genotype. The two predominant sequence-types ST1 and ST47 trigger opposite inflammatory response that could be related to the host susceptibility.

description: A highly integrated, high performance, and re-configurable device, which is designed for the Nitrogen-Vacancy center based quantum applications, is reported. The digital compartment of the device is fully implemented in a Field-Programmable-Gate- Array. The digital compartment is designed to manage the multi-function digital waveform generation and the Time-to-Digital-Convertors. The device provides two Arbitrary-Waveform-Generator channels which operate at a 1 Gsps sampling rate with a maximum bandwidth of 500 MHz. There are twelve pulse channels integrated in the device with a 50 ps time resolution in both duration and delay. The pulse channels operate with the 3.3 V Transistor-Transistor logic. The FPGA-based Timeto- Digital-Convertor provides a 23-ps time measurement precision. A data accumulation module, which can record the input count rate and the distributions of the time measurement, is also available. A Digital-to-Analog-Convertor board is implemented as the analog compartment, which converts the digital waveforms to analog signals with 500 MHz low-pass-filters. All the input and output channels of the device are equipped with 50 Sub-Miniature version A termination. The hardware design is modularized thus it can be easily upgraded with compatible components. The device is suitable to be applied in the quantum technologies based on the N-V centers, as well as in other quantum solid state systems, such as quantum dots, phosphorus doped in silicon and defect spins in silicon carbide.
Poetics of the machine: machine writing and the AI literature frontier

description: Machine writing is defined in this thesis as the explicit use of computational methods to compose literature. The form has seen a surge in popularity as part of academic and journalistic conversations regarding the role of artificial intelligence (AI) in creative practices. Currently, creative coders, literary scholars and computer scientists are grappling with what does and does not constitute AI-penned literature, occasionally leading into conversations regarding singularity-type events. This thesis seeks to ground the conversation, focusing on past and present machine writing and evaluating how it relates to the idea of AI literature. To do this, the common theme of comparing literature by machines to literature by humans will be challenged. Through close readings of both output and code, I argue that to understand AI literature, we must explore the poetics and consequences unique to machine writing. In order to highlight changes in the form, this thesis will develop a history of machine writing. Trajectories from the language games of the OuLiPo group and the Beat Generation's cut-up experiments to Twitterbots and algorithmically generated novels will be charted. Through analysis that focuses on both the literary output of these machines and their constraints/codes, the distinctly inhuman qualities of machine writing will be explored. This analysis will reveal the capacity of machine writing to transform texts, create unthinkable worlds, and mirror the anxieties of the information age. In short, machine writing will be analysed on the basis of its own literary and linguistic techniques, and the effects these techniques produce, establishing a sort of "machine poetics". Uncovering the poetics of these machines then reveals several other concerns. Authorship becomes complicated by the use of algorithms, corpora and other authorial forces. Further, the utility of machine writing to both promulgate and dismantle oppressive structures through unthinking automation is revealed. In exploring these topics, this thesis maps the current climate of machine writing literature and provides insight into what may lie beyond the AI literature frontier.

description: In a previous paper, we derived necessary and sufficient conditions for the invertibility of square submatrices of the Pascal upper triangular matrix. To do so, we established a connection with the two-point Birkhoff interpolation problem. In this paper, we extend this result by deriving a formula for the rank of submatrices of the Pascal matrix. Our formula works for both square and non-square submatrices. We also provide bases for the row and column spaces of these submatrices. Further, we apply our result to one-point lacunary polynomial approximation.

description: Objective: The optimal interval before receiving SARS-COV-2 vaccination for patients who have received anti-CD 20 monoclonal antibodies remains unclear. Methods: We consideredoriginal studies up to 29 October 2022 and conducted searches in Embase,Medrxiv, PubMed, and SSRN. We excluded search results that did not match ourresearch question’s subject. Human immune response outcomes were analyzed inpatients who had previously received anti-CD20 antibody therapy. We analyzedthe collected results using sensitivity curves andforest plots. Results: Twenty-eight studieswith a total of 1455 subjects receiving anti-CD20 monoclonal antibodies wereincluded in the present analysis. The humoral immune response rates to the timebetween the last anti-CD20 treatment and vaccination for 3-6 months, 6 months,6-9 months, and 9-12 months were 0.23 (95% CI 0.14 to 0.36), 0.36 (95% CI 0.19to 0.58), 0.49 (95% CI 0.35 to 0.64) and 0.64 (95% CI 0.48 to 0.77),respectively. The humoral immune response rates were0.16 (95% CI 0.03 to 0.57) when B cell was 0/ul, and 0.49 (95% CI 0.38 to 0.61)when B cells were more than 5/ul. The humoral immune response ratefor multiple sclerosis was 0.39 (95% CI 0.22 to 0.60) and 0.48 (95% CI 0.29 to0.68) for B-cell non-Hodgkin lymphoma. The area underneath the curve(AUC) was 0.69 with a cut-off value of 5.5 months. Conclusions: The present resultssuggested that the optimal interval for SARS-COV-2 vaccination after the finaldose of anti-CD20 monoclonal antibody was 5.5 months.

description: Wave functions of a new functional kind have been proposed for Helium-like atoms in this work . These functions explicitly depend on interelectronic and hyperspherical coordinates. The best ground state energy for the Helium atom $ -2.903724376677 a.u.$ has been calculated with variational method with basis set of simple functions with a single exponential parameter. To the author's knowledge, this is the best result with use of hyperspherical coordinates so far. Comparable result has been obtained for the hydrogen anion. For Helium atom, our best wave functions matched the Kato cusp conditions within the accuracy below $6.10^{-4} $. An important feature of proposed wave functions is the inclusion of negative powers of $R=\sqrt(r^{2}_{1}+r^{2}_{2})$ in combination with positive powers of $r_{12}$ into the wave function. We showed that this is necessary condition for proposed wave function to be a formal solution of Schrödinger equation.

description: Cystic fibrosis (CF) disease is characterized by an intense airway inflammatory response mediated by neutrophils and chronic respiratory infections caused by P. aeruginosa. High levels of the complement component C5a, the strongest neutrophil chemoattractant molecule, are commonly found in the CF lung and have been associated with a worsening of the disease. In this study, we investigated how the isolates from CF patients modulate the levels of C5a and identified the bacterial factors involved. We demonstrated that most isolates from airway chronic infections induce the production and accumulation of C5a, an effect attributable to the loss of C5a cleavage by the exoproteases alkaline protease (AprA) and elastase B (LasB). Furthermore, we found that lack of the bacterial protease-dependent C5a degradation is due to mutations in the master regulator LasR. Thus, complementation of a non-C5a-cleaving CF isolate with a functional wild-type LasR restored its ability to express both proteases, cleave C5a and reduce neutrophil recruitment in vitro. These findings suggest that the non-cleaving C5a phenotype acquired by the LasR variants frequently isolated in CF patients may account for the strong neutrophilia and general neutrophil dysfunction predisposing toward increased inflammation and reduced bacterial clearance described in CF patients.

description: We use a set of N-body simulations employing a modified gravity (MG) model with Vainshtein screening to study matter and halo hierarchical clustering. As test-case scenarios we consider two normal branch Dvali-Gabadadze-Porrati (nDGP) gravity models with mild and strong growth rate enhancement. We study higher-order correlation functions $ξ_n(R)$ up to $n=9$ and associated hierarchical amplitudes $S_n(R)\equivξ_n(R)/σ(R)^{2n-2}$. We find that the matter PDFs are strongly affected by the fifth-force on scales up to $50h^{-1}$Mpc, and the deviations from GR are maximised at $z=0$. For reduced cumulants $S_n$, we find that at small scales $R\leq10h^{-1}$Mpc the MG is characterised by lower values, with the deviation growing from $7\%$ in the reduced skewness up to even $40\%$ in $S_5$. To study the halo clustering we use a simple abundance matching and divide haloes into thee fixed number density samples. The halo two-point functions are weakly affected, with a relative boost of the order of a few percent appearing only at the smallest pair separations ($r\leq 5h^{-1}$Mpc). In contrast, we find a strong MG signal in $S_n(R)$'s, which are enhanced compared to GR. The strong model exhibits a $>3σ$ level signal at various scales for all halo samples and in all cumulants. In this context, we find that the reduced kurtosis to be an especially promising cosmological probe of MG. Even the mild nDGP model leaves a $3σ$ imprint at small scales $R\leq3h^{-1}$Mpc, while the stronger model deviates from a GR-signature at nearly all scales with a significance of $>5σ$. Since the signal is persistent in all halo samples and over a range of scales, we advocate that the reduced kurtosis estimated from galaxy catalogues can potentially constitute a strong MG-model discriminatory as well as GR self-consistency test.

Gravitational domain walls and the dynamics of $G$

description: From the point of view of elementary particle physics the gravitational constant $G$ is extraordinarily small. This has led to ask whether it could have decayed to its present value from an initial one commensurate with microscopical units. A mechanism that leads to such a decay is proposed herein. It is based on assuming that $G$ may take different values within regions of the universe separated by a novel kind of domain wall, a "G-wall". The idea is implemented by introducing a gauge potential $A_{μνρ}$, and its conjugate $D$, which determines the value of $G$ as an integration constant rather than a fundamental constant. The value of $G$ jumps when one goes through a $G$-wall. The procedure extends one previously developed for the cosmological constant, but the generalization is far from straightforward: (i) The intrinsic geometry of a $G$-wall is not the same as seen from its two sides, because the second law of black hole thermodynamics mandates that the jump in $G$ must cause a discontinuity in the scale of length. (ii) The size of the decay step in $G$ is controlled by a function $G(D)$ which may be chosen so as to diminish the value of $G$ towards the asymptote $G=0$, without fine tuning. It is shown that: (i) The dynamics of the gravitational field with $G$ treated as a dynamical variable, coupled to $G$-walls and matter, follows from an action principle, which is given. (ii) A particle that impinges on a $G$-wall may be refracted or reflected. (iii) The various forces between two particles change when a $G$-wall is inserted in between them. (iv) $G$-walls may be nucleated trough tunneling and thermal effects. The semiclassical probabilities are evaluated. (v)~If the action principle is constructed properly, the entropy of a black hole increases when the value of the gravitational constant is changed through the absorption of a G-wall by the hole.
