description: Quasielastic neutrino scattering is an important aspect of the experimental program to study fundamental neutrino properties including neutrino masses, mixing angles, the mass hierarchy and CP-violating phase. Proper interpretation of the experiments requires reliable theoretical calculations of neutrino-nucleus scattering. In this paper we present calculations of response functions and cross sections by neutral-current scattering of neutrinos off $^{12}$C. These calculations are based on realistic treatments of nuclear interactions and currents, the latter including the axial-, vector-, and vector-axial interference terms crucial for determining the difference between neutrino and anti-neutrino scattering and the CP-violating phase. We find that the strength and energy-dependence of two-nucleon processes induced by correlation effects and interaction currents are crucial in providing the most accurate description of neutrino-nucleus scattering in the quasielastic regime.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: We present a derivation of the chiral ring relations, arising in ${\cal N}=1$ gauge theories in the presence of (anti-)self-dual background gravitational field $G_{αβγ}$ and graviphoton field strength $F_{αβ}$. These were previously considered in the literature in order to prove the relation between gravitational F-terms in the gauge theory and coefficients of the topological expansion of the related matrix integral. We consider the spontaneous breaking of ${\cal N} =2$ to ${\cal N} =1$ supergravity coupled to vector- and hyper-multiplets, and take a rigid limit which keeps a non-trivial $G_{αβγ}$ and $F_{αβ}$ with a finite supersymmetry breaking scale. We derive the resulting effective, global, ${\cal N}=1$ theory and show that the chiral ring relations are just a consequence of the standard ${\cal N}=2$ supergravity Bianchi identities . We can also obtain models with matter in different representations and in particular quiver theories. We also show that, in the presence of non-trivial $F_{αβ}$, consistency of the Konishi-anomaly loop equations with the chiral ring relations, demands that the gauge kinetic function and the superpotential, a priori unrelated for an ${\cal N}=1$ theory, should be derived from a prepotential, indicating an underlying ${\cal N}=2$ structure.

description: Full Waveform Inversion (FWI) is slowly becoming the standard for velocity estimation from seismic data. It uses the full wave equation to estimate high resolution models capable of recovering finer details compared to traditional methods like tomography. FWI is constructed as a least squares optimization problem that iteratively updates an initial model until the misfit between modeled and observed data are within a pre-specified tolerance. The local nature of FWI makes it sensitive to the choice of starting model which has to be in the global minimum trough of the misfit function. If the starting model lies outside the global minimum trough, FWI converges to a local minima giving an incorrect estimation of subsurface properties. In this thesis, I eliminate the sensitivity to the starting model when performing FWI. This is done by recasting FWI into a global optimization problem using a combination of sparse parameterization methods. The starting model is generated by a global optimization method that is not sensitive to the starting model. The result from the global optimization method is then used as a starting model for conventional FWI using a dense set of parameters. In chapter 2, I apply global optimization with a sparse parameterization technique for 2D models using a combination of interfaces and velocities. Chapter 3 extends the sparse parameterization for salt bodies using ellipse sets and level-set methods. Lastly, chapter 4 extends sparse parameterization in three dimensions to perform FWI without a starting guess. I demonstrate that the proposed approaches are not sensitive to the source of starting model and discuss some sources of uncertainty. Another issue that prevents implementation of FWI on a regular basis is its computational cost. Expensive forward evaluations need to be performed multiple times across several iterations to obtain the final model. It is of particular significance in 3D where in addition to posing a computational cost problem, it also creates a data reversal problem when computing the gradient. I propose two approaches to reduce the computational cost of forward modeling and gradient computation in the time and frequency domains. The frequency domain approach discussed in chapter 5 exploits the contribution of unchanging zones in an inversion workflow to be reused over subsequent iterations of FWI. The final chapter discusses how to run a gradient computation on GPUs using faster interconnect and on-node memory. I provide a template to apply it to a general adjoint problem with specific example on FWI. I obtain a 20-40% and 82-207% improvement in runtimes in the frequency and time domain, respectively, using the proposed methods.

description: We establish an inclusion relation between two uniform models of random k-graphs (for constant k ≥ 2) on n labeled vertices: G(k)(n, m), the random k-graph with m edges, and R(k)(n, d), the random d-regular k-graph. We show that if n log n≪m≪nk we can choose d = d(n) ~ km/n and couple G(k)(n, m) and R(k)(n, d) so that the latter contains the former with probability tending to one as n → ∞. This extends some previous results of Kim and Vu about “sandwiching random graphs”. In view of known threshold theorems on the existence of different types of Hamilton cycles in G(k)(n, m), our result allows us to find conditions under which R(k)(n, d) is Hamiltonian. In particular,for k ≥ 3 we conclude that if nk−2≪d≪nk−1, then a.a.s. R(k)(n, d) containsa tight Hamilton cycle.

description: Often the rows (cases, objects) of a dataset have weights. For instance, the weight of a case may reflect the number of times it has been observed, or its reliability. For analyzing such data many rowwise weighted techniques are available, the most well known being the weighted average. But there are also situations where the individual cells (entries) of the data matrix have weights assigned to them. The purpose of this note is to provide an approach to analyze such data. We define a cellwise weighted likelihood function, that corresponds to a transformation of the dataset which we call unpacking. Using this weighted likelihood one can carry out multivariate statistical methods such as maximum likelihood estimation and likelihood ratio tests. We pay particular attention to the estimation of covariance matrices, because these are the building blocks of much of multivariate statistics. An R implementation of the cellwise maximum likelihood estimator is provided, which employs a version of the EM algorithm. Also a faster approximate method is proposed, which is asymptotically equivalent to it.

description: To explain the broad-band spectral energy distributions (SED) of Seyfert nuclei and QSOs, we study the emission spectrum emerging from a vertical disk-corona structure composed of a two-temperature plasma by solving hydrostatic equilibrium and radiative transfer self-consistently. Our model can nicely reproduce the soft X-ray excess with alpha (L_frequency proportional to the frequency to the power of -alpha) of about 1.5 and the hard tail extending to about 50 keV with alpha about 0.5. The different spectral slopes (alpha about 1.5 below 2 keV and about 0.5 above) are the results of different emission mechanisms: unsaturated Comptonization in the former and a combination of Comptonization, bremsstrahlung, and reflection of the coronal radiation at the disk-corona boundary in the latter.

description: In the 2016-2017 austral summer, the University of Texas Institute for Geophysics (UTIG) and the Korean Polar Research Institute (KOPRI) collaborated to perform a helicopter- based radar and laser altimeter survey on the Lower David Lakes Catchment. This survey ties in with (and fills some of the gaps in) an ICECAP survey of the Drygalski Ice Tongue and the David Glacier grounding zone from 2011 and 2012 [Blankenship et al., 2017] in order to provide a 5 km resolution survey extending from the grounding line past the first two active subglacial lakes identified by Smith et al. [2009]. While this is far from the first aerogeo- physical survey of an active lake system, it is one of the most extensive, and provides higher resolution boundary conditions and basal characteristics that will enable process studies of these enigmatic features.

Dammed rivers
Hydropeaking
River temperature
Surface water-groundwater interactions

description: The damming of rivers has resulted in multitude of environmental impacts to river ecosystems. The focus of this dissertation is to assess how dams used for hydroelectric power generation influence surface water-groundwater exchange. The exchange of surface water with groundwater has been demonstrated to be an important mechanism regulating nutrient dynamics in rivers. Hydroelectric dams are often “hydropeaked,” which is when discharge from the dam is increased/decreased in accordance with daily patterns of electricity demand. This creates high frequency river stage fluctuations that enhance the connectivity between rivers and groundwater. The central theme explored throughout this dissertation is how hydropeaking effects the movement of water, dissolved solutes, and heat between rivers and their sediments. Much of the research presented in this dissertation uses numerical models to explore how properties of the river (stage, chemistry, temperature) and subsurface (hydraulic conductivity, groundwater levels) control exchanges of fluid, heat, and solutes, and characterizing how those fluxes alter the chemistry and temperature of sediments near the river. Two of the studies are entirely modeling-based, focusing on the lateral exchanges of fluid and solutes between rivers and their riparian aquifers caused by hydropeaking. The results provide insight into how dam release and subsurface properties influence surface water-groundwater exchange and also the distance downstream from a dam that exchanges occur over. Other key findings relate to how hydraulic conductivity and groundwater flow conditions of the riparian aquifer control fluid and solute exchange, how far river-sourced solutes propagate into the riparian zone, and factors influencing aerobic respiration in the banks of hydropeaked rivers. In another study, field observations of riverbed temperatures from a hydropeaked river are combined with flow and heat transport modeling. The results demonstrate that hydropeaking releases can strongly influence the temperature of the riverbed near the river bank, but not over the majority of the channel. A final study uses temperature observations from hundreds of rivers across the United States to characterize the mean daily temperature and daily temperature range in different ecoregions. The results from this assessment demonstrate how the thermal regimes of rivers near dams have been altered.

description: Many organisms can remember locations they have previously visited during a search. Visual search experiments have shown exploration is guided away from these locations, reducing the overlap of the search path before finding a hidden target. We develop and analyze a two-layer neural field model that encodes positional information during a search task. A position-encoding layer sustains a bump attractor corresponding to the searching agent's current location, and search is modeled by velocity input that propagates the bump. A memory layer sustains persistent activity bounded by a wave front, whose edges expand in response to excitatory input from the position layer. Search can then be biased in response to remembered locations, influencing velocity inputs to the position layer. Asymptotic techniques are used to reduce the dynamics of our model to a low-dimensional system of equations that track the bump position and front boundary. Performance is compared for different target-finding tasks.

description: Arvicoline rodents (voles, lemmings, and muskrats) are important taxa for characterizing and defining the North American Land Mammal Ages (NALMAs) of the Pliocene and Pleistocene. They are the basis for finer-scale temporal and spatial resolution and have been used to generate the divisions of the Blancan and Irvingtonian NALMAs. The profuse fossil record of arvicolines has never been reconciled with modern phylogenetic techniques, because the fossil record is almost exclusively isolated teeth or tooth-bearing elements. Here I present the most taxonomically robust (n=134) and genetically well sampled (n=5 genes) molecular phylogeny of arvicoline rodents. I used Parsimony, Maximum Likelihood, and Bayesian Inference methodologies to explore the systematic relationships of the clade. Seven fossil calibrations were used to place a series of temporal constraints on the tree to generate the first time-calibrated phylogeny of arvicoline rodents and I found that the clade originated in the Miocene at 6.5 Ma. This hypothesis was subsequently used to model speciation rates, and the patterns of paleobiogeography of the group in the R program BioGeoBEARS. I hypothesize that arvicoline rodents originated in Asia and that dispersal was asymmetric from west (Asia) to east (North America) with at least nine dispersal events between the two continents. My data indicate an origination of Lemmiscus at 5 Ma and the origination of the Synaptomys clade at 3.8 Ma, which supports previously problematic reports of both taxa from Hagerman, ID. This leaves the Blancan V division (as previously defined by the immigration of Synaptomys at 2.5 Ma) undefined and this leaves the Blancan undifferentiated from 4. Ma to the start of the Irvingtonian at 1.9 Ma. This is a novel approach of reconciling biochronology and probabilistic paleobiogeography. I also obtained the first radiometric age of the fauna of Cumberland Bone Cave using a combined Uranium Series and Electron Spin Resonance (ESR) approach, the first date of a middle Pleistocene site in Northeastern North America. Results indicate an age of the fauna of 756 +87/-98 ka which provides an important temporal anchor point from which to begin to understand the faunal dynamics of the region during the Pleistocene.

description: SND@LHC is a compact and stand-alone experiment designed to perform measurements with neutrinos produced at the LHC in the pseudo-rapidity region of ${7.2 < η< 8.4}$. The experiment is located 480 m downstream of the ATLAS interaction point, in the TI18 tunnel. The detector is composed of a hybrid system based on an 830 kg target made of tungsten plates, interleaved with emulsion and electronic trackers, also acting as an electromagnetic calorimeter, and followed by a hadronic calorimeter and a muon identification system. The detector is able to distinguish interactions of all three neutrino flavours, which allows probing the physics of heavy flavour production at the LHC in the very forward region. This region is of particular interest for future circular colliders and for very high energy astrophysical neutrino experiments. The detector is also able to search for the scattering of Feebly Interacting Particles. In its first phase, the detector will operate throughout LHC Run 3 and collect a total of 250 $\text{fb}^{-1}$.

description: Above the saturation field, geometrically frustrated quantum antiferromagnets have dispersionless low-energy branches of excitations corresponding to localized spin-flip modes. Transition into a partially magnetized state occurs via condensation of an infinite number of degrees of freedom. The ground state below the phase transition is a magnon crystal, which breaks only translational symmetry and preserves spin-rotations about the field direction. We give a detailed review of recent works on physics of such phase transitions and present further theoretical developments. Specifically, the low-energy degrees of freedom of a spin-1/2 kagomé antiferromagnet are mapped to a hard hexagon gas on a triangular lattice. Such a mapping allows to obtain a quantitative description of the magnetothermodynamics of a quantum kagomé antiferromagnet from the exact solution for a hard hexagon gas. In particular, we find the exact critical behavior at the transition into a magnon crystal state, the universal value of the entropy at the saturation field, and the position of peaks in temperature- and field-dependence of the specific heat. Analogous mapping is presented for the sawtooth chain, which is mapped onto a model of classical hard dimers on a chain. The finite macroscopic entropies of geometrically frustrated magnets at the saturation field lead to a large magnetocaloric effect.

description: The main purpose of this study is to develop a pipeline for COVID-19 detection from a big and challenging database of Computed Tomography (CT) images. The proposed pipeline includes a segmentation part, a lung extraction part, and a classifier part. Optional slice removal techniques after UNet-based segmentation of slices were also tried. The methodologies tried in the segmentation part are traditional segmentation methods as well as UNet-based methods. In the classification part, a Convolutional Neural Network (CNN) was used to take the final diagnosis decisions. In terms of the results: in the segmentation part, the proposed segmentation methods show high dice scores on a publicly available dataset. In the classification part, the results were compared at slice-level and at patient-level as well. At slice-level, methods were compared and showed high validation accuracy indicating efficiency in predicting 2D slices. At patient level, the proposed methods were also compared in terms of validation accuracy and macro F1 score on the validation set. The dataset used for classification is COV-19CT Database. The method proposed here showed improvement from our precious results on the same dataset. In Conclusion, the improved work in this paper has potential clinical usages for COVID-19 detection and diagnosis via CT images. The code is on github at https://github.com/IDU-CVLab/COV19D_3rd

To this end, the X-ray emission data collected by the IGEX collaboration are analyzed and compared with the spectrum of the spontaneous photon emission process predicted by collapse models. This study allows the obtainment of the most stringent limits within a relevant range of the CSL model parameters, with respect to any other method. The collapse rate $λ$ and the correlation length $r_C$ are mapped, thus allowing the exclusion of a broad range of the parameter space.

description: The similarities in the experimental indications for multinucleon mechanisms in $(γ,p)$ and $(e,e'p)$ processes are pointed out. For both types of reactions, the substantial role of two-nucleon emission processes for transitions to high excitation energies in the residual nucleus is stressed. A microscopic model for the calculation of the two-body knockout contributions to the inclusive $(γ,N)$ reaction is presented. It is based on an unfactorized formalism for the calculation of electromagnetically induced two-nucleon emission cross sections. The model is shown to yield a reasonable description of the overall behaviour of the $^{12}$C$(γ,p)$ and $^{12}$C$(γ,n)$ data at high excitation energies in the residual nucleus. In the calculations effects from non-resonant and resonant pion exchange currents are included. Photoabsorption on these currents are predicted to produce the major contributions to the exclusive $^{16}$O$(γ,n_0)^{15}$O process at photonenergies above the pion threshold. Double differential cross sections for photon induced $pp$ and $pn$ emission from $^{16}$O are calculated and compared with the data.

description: This study aims to alleviate the widespread case of Internet addiction caused by the proliferation of Internet cafés or computer gaming shops, which is a common dilemma of parents residing in one of the cities in Metro Manila (hereinafter referred to as the “City” for this study). It is noteworthy that the officials of the City havepassed a resolution (hereinafter referred to as the “City Ordinance” in this study) to regulate Internet café operations in the City. However, there is a need to address whether the City Ordinance has indeed served its purpose as deemed by this study. Responses obtained from Internet café users in this study confirmed thatexcessive visits to computer shops are common among young children in the City. These responses were corroborated with the results of the survey conducted among parents. Both results confirmed that there is an Internet café–related problem among the youth in the City that threatens their good education and bright future. Furthermore, these results suggested that the implementation of and information dissemination done for the City Ordinance, if any, were ineffective. Given the importance of communication in the success of any public policy, and the changing information environment, the above premise suggests that the very essence of this study—that is, the method used in the dissemination and campaign of the City Ordinance—was examined.

description: We propose two statistical tests to investigate how we see the nuclear region (r < 0.1 pc) of Narrow-Line Seyfert 1 galaxies (NLS1s). 1) The high-ionization nuclear emission-line region (HINER) test: Seyfert 1 galaxies (S1s) have systematically higher flux ratios of [Fe VII] lambda 6087 to [O III] lambda 5007 than Seyfert 2 galaxies (S2s). This is interpreted in that a significant part of the [Fe VII] lambda 6087 emission arises from the inner walls of dusty tori that cannot be seen in S2s (Murayama & Taniguchi 1998a,b). 2) The mid-infrared test: S1s have systematically higher flux ratios of the L band (3.5 micrometer) to the IRAS 25 micrometer band than S2s. This is also interpreted in that a significant part of the L band emission arises from the inner walls of dusty tori, because the tori are optically thick enough to absorb the L band emission if the tori are viewed nearly edge on (Murayama et al. 2000). Applying these tests to a sample of NLS1s, we have found that the NLS1s possibly have nearly the same properties as S1s.

description: Using a point-charge calculation of the electrostatic crystal field, we determine the non-degenerate orbital ground state of the ferromagnetic Mott insulator YTiO3, which is found to agree perfectly with experiment. Based on the orbital order, we obtain by perturbation theory an effective spin Hamiltonian that describes the magnetic superexchange between nearest-neighbor Ti ions. The superexchange Hamiltonian includes, in addition to the isotropic Heisenberg coupling, antisymmetric (Dzyaloshinskii-Moriya) and symmetric anisotropy terms, caused by the spin-orbit interaction on the Ti ions. We find ferromagnetic Heisenberg couplings for Ti-Ti bonds in the crystallographic ab planes, but antiferromagnetic ones for Ti-Ti bonds between planes, in contradiction with experiment (which gives ferromagnetic couplings for both). Difficulties in calculating realistic values for the isotropic couplings of YTiO3 have been already reported in the literature. We discuss possible origins for these discrepancies. However, the much smaller values we obtain for the symmetric and antisymmetric anisotropies may be expected to be reliable. We therefore combine the experimentally-deduced isotropic coupling with the calculated anisotropic ones to determine the magnetic order of the Ti ions, which is found to be in satisfactory agreement with experiment. Based on this magnetic order, we derive the spin-wave spectrum. We find an acoustic branch with a very small zone-center gap and three optical spin-wave modes with sizeable zone-center gaps. The acoustic branch reproduces the one reported in experiment, and the optical ones are in a satisfactory agreement with experiment, upon a proper folding of the magnetic Brillouin zone.

description: We first consider the following problem. We are given a fixed perfect matching M of [n] and we add random edges one at a time until there is a Hamilton cycle containing M. We show that w.h.p. the hitting time for this event is the same as that for the first time there are no isolated vertices in the graph induced by the random edges. We then use this result for the following problem. We generate random edges and randomly color them black or white. A path/cycle is said to \emph{zebraic} if the colors alternate along the path. We show that w.h.p. the hitting time for a zebraic Hamilton cycle coincides with every vertex meeting at least one edge of each color. We then consider some related problems and extend to multiple colors.
Dead ends and rationality of complete growth series

description: The complete growth series of a finitely generated group is given by $\sum_{n\ge 0} A_ns^n$, where $A_n$ is the sum of elements of length $n$ in the group semiring. We study the $\mathbb NG$-rationality and $\mathbb NG$-algebraicity of such series. We show that having dead ends of arbitrarily large depths is an obstruction to $\mathbb NG$-rationality. In the case of the $3$-dimensional Heisenberg group $H_3(\mathbb Z)$, we prove that the complete series is not $\mathbb NG$-algebraic for any generating set. Dead ends are also used to show that complete growth series of higher Heisenberg groups are not $\mathbb NG$-rational for specific generating sets. Using a more general version of this obstruction, we prove that complete growth series of some lamplighter groups are not $\mathbb NG$-rational either.

description: The Dirac equation is exactly solved for a pseudoscalar linear plus Coulomb-like potential in a two-dimensional world. This sort of potential gives rise to an effective quadratic plus inversely quadratic potential in a Sturm-Liouville problem, regardless the sign of the parameter of the linear potential, in sharp contrast with the Schroedinger case. The generalized Dirac oscillator already analyzed in a previous work is obtained as a particular case.

description: Globally, over half of all rivers are regulated in some way. In some cases, river regulation is the dominant factor governing fluid exchange and soil gas dynamics in the hyporheic and unsaturated zones of the river banks. Where this is the case, it is important to understand the effects that an artificially-induced change in river stage can have on the chemical, plant, and microbial components of the unsaturated zone. Daily releases from an upstream dam cause rapid stage fluctuations in the Lower Colorado River east of Austin, Texas. Previous findings indicate that meter-scale changes in river stage propagate through the bank and are dampened to centimeter-scale pulses in the water table. We propose that these conditions create an area in the subsurface that is subjected to frequent cycles of saturation and drainage (the ‘active zone’), supporting enhanced microbial oxidation of organic carbon and acting as a biogeochemical filter. CO2 production through the active zone appears to be decoupled from patterns of diurnal respiration but closely linked to increased soil-water content following a water table rise. Our data indicate that neither surface water nor groundwater is the source of carbon for this zone. Instead, two sources of carbon are possible: 1) litter-derived carbon is leaching down through the soil column into the active zone, or 2) at low water contents particulate organic carbon accumulates in macropores where it is enzymatically decomposed to labile carbon. Additionally, our results suggest that the active zone may sustain denitrifying activity and a region of methanogenesis.
Size scaling of failure strength with fat-tailed disorder in a fiber bundle model

description: We investigate the size scaling of the macroscopic fracture strength of heterogeneous materials when microscopic disorder is controlled by fat-tailed distributions. We consider a fiber bundle model where the strength of single fibers is described by a power law distribution over a finite range. Tuning the amount of disorder by varying the power law exponent and the upper cutoff of fibers' strength, in the limit of equal load sharing an astonishing size effect is revealed: For small system sizes the bundle strength increases with the number of fibers and the usual decreasing size effect of heterogeneous materials is only restored beyond a characteristic size. We show analytically that the extreme order statistics of fibers' strength is responsible for this peculiar behavior. Analyzing the results of computer simulations we deduce a scaling form which describes the dependence of the macroscopic strength of fiber bundles on the parameters of microscopic disorder over the entire range of system sizes.

description: The very first recruitment for a public relations practitioner in Malaysia was encountered in 1948 and was advertised by the federal government of the British Colony in Malaya. This paper examines the subsequent advertisements after Malaya sought independence from the British colonial government. A total of eleven recruitment advertisements were found before the formation of Malaysia on the 16th
September 1963. This paper outlines the advertisers, the titles of positions, as well as their qualifications and duties. The results show that the job requirement mainly came from the federal and local governments. Generally, the duties were related to information services and some specific responsibilities.

description: As a promising distributed machine learning paradigm, Federated Learning (FL) has attracted increasing attention to deal with data silo problems without compromising user privacy. By adopting the classic one-to-multi training scheme (i.e., FedAvg), where the cloud server dispatches one single global model to multiple involved clients, conventional FL methods can achieve collaborative model training without data sharing. However, since only one global model cannot always accommodate all the incompatible convergence directions of local models, existing FL approaches greatly suffer from inferior classification accuracy. To address this issue, we present an efficient FL framework named FedCross, which uses a novel multi-to-multi FL training scheme based on our proposed multi-model cross-aggregation approach. Unlike traditional FL methods, in each round of FL training, FedCross uses multiple middleware models to conduct weighted fusion individually. Since the middleware models used by FedCross can quickly converge into the same flat valley in terms of loss landscapes, the generated global model can achieve a well-generalization. Experimental results on various well-known datasets show that, compared with state-of-the-art FL methods, FedCross can significantly improve FL accuracy within both IID and non-IID scenarios without causing additional communication overhead.

description: We present an explicit and simple approximation for the superadiabatic excess (over ideal gas) free power functional, admitting the study of the nonequilibrium dynamics of overdamped Brownian many-body systems. The functional depends on the local velocity gradient and is systematically obtained from treating the microscopic stress distribution as a conjugate field. The resulting superadiabatic forces are beyond dynamical density functional theory and are of viscous nature. Their high accuracy is demonstrated by comparison to simulation results.

description: The issue of deliberate forest fires that set illegally in Indonesia by plantation companies in their slashand-burn forests to clear lands for lucrative palm oil plantations and its caused transboundary haze became a hot issue for discussion. These fires have a negative influence on Indonesia and its neighbourhood countries, especially on their financial and human resources such as environment,
economy, properties, and people. Using the right strategies in responding to any crisis determines the success of its management and coping with that crisis with minimal losses. This study aimed to examine the communication crisis response by Indonesia to this crisis by using image repair theory. Also, this study examined how image repair strategies were used by Indonesia. This study analysed
the content of news stories from the website of the New Straits Times newspaper. The time frame of this study was from 2015 to 2019. A total of 87 news stories have pertained to Indonesian response, and 37 stories included image repair strategies. Among the strategies of image repair theory, corrective action strategy was the most dominant with 70%, followed by 10.8% for each shift the blame and attack accuser. The least used strategies were mortification and simple denial with 5.4% and 2.7% respectively.
