description: This study assessed the drinking water quality and associated human health risks in Epe Town, Lagos State, Nigeria as a case study. Available water infrastructures and associated water quality were examined. An assessment of the accessibility of water supply to the inhabitants of Epe Town was also carried out. Three hundred structured questionnaires were administered to gather information about water supply, respondents' daily water usage volume, and the time taken to access water. The research integrates spatial and quantitative analyses of water quality parameters such as pH, EC, turbidity, TDS, DO, Na+, and Cl- with qualitative assessments of residents' experiences and perceptions regarding water scarcity and its daily-life consequences. The results revealed inadequate water infrastructures, leading to limited access to clean water. Residents face challenges in obtaining water, often investing valuable time and resources in securing this essential resource. The study underscores the implications of these constraints for achieving SDG 3. Moreover, the physico-chemical analysis of underground water demonstrates generally good water quality; but cautions against elevated total dissolved solids (TDS) and dissolved oxygen (DO) levels, which can pose health risks. The study emphasizes the necessity for comprehensive water management strategies and proper infrastructure development to mitigate the negative impacts of water supply on public health, in pursuit of achieving the SDGs.

description: On a family of classical dynamical systems on the 2-torus, we perform a discretization procedure similar to the Anti-Wick quantization. Such a discretization is performed by using a particular class of states, fulfilling an appropriate dynamical localization property, typical of quantum Coherent States. The same set of states is involved in the construction of a quantum entropy, that we test on the discrete approximants; a correspondence with the classical metric entropy of Kolmogorov-Sinai is found only over time scales that are logarithmic in the discretization parameter.

Search for V+A current in top quark decay in ppbar collisions at sqrt{s}=1.96 TeV

description: We report an upper limit on the fraction of V+A current, $f_{V+A}$, in top quark decays, using approximately 700 pb$^{-1}$ of $p\bar{p}$ collisions at $\sqrt{s}$=1.96 TeV acquired by the upgraded Collider Detector at Fermilab. For the decay $t \to Wb \to \ell νb$ (where $\ell=e$ or $μ$), the invariant mass of the charged lepton and the bottom quark jet is sensitive to the polarization of the $W$ boson. We determine $f_{V+A} = -0.06 \pm 0.25$ given a top quark mass of 175 GeV/$c^{2}$. We set an upper limit on $f_{V+A}$ of 0.29 at the 95% confidence level, which represents an improvement by a factor of two on the previous best direct limit.

description: We are seeing an extensive proliferation of wireless devices including various types and forms of sensor nodes that are increasingly becoming ingrained in our daily lives. There has been a significant growth in wireless devices capabilities as well. This proliferation and rapid growth of wireless devices and their capabilities has led to the development of many distributed sensing and computing applications. In this dissertation, we propose and evaluate novel, efficient approaches for localization and computation offloading that harness distributed sensing and computing in wireless networks. In a significant part of this dissertation, we exploit distributed sensing to create efficient localization applications. First, using the sensing power of a set of Radio frequency (RF) sensors, we propose energy efficient approaches for target tracking application. Second, leveraging the sensing power of a distributed set of existing wireless devices, e.g., smartphones, internet-of-things devices, laptops, and modems, etc., we propose a novel approach to locate spectrum offenders. Third, we build efficient sampling approaches to select mobile sensing devices required for spectrum offenders localization. We also enhance our sampling approaches to take into account selfish behaviors of mobile devices. Finally, we investigate an attack on location privacy where the location of people moving inside a private area can be inferred using the radio characteristics of wireless links that are leaked by legitimate transmitters deployed inside the private area, and develop the first solution to mitigate this attack. While we focus on harnessing distributed sensing for localization in a big part of this dissertation, in the remaining part of this dissertation, we harness the computing power of nearby wireless devices for a computation offloading application. Specially, we propose a multidimensional auction for allocating the tasks of a job among nearby mobile devices based on their computational capabilities and also the cost of computation at these devices with the goal of reducing the overall job completion time and being beneficial to all the parties involved.

description: High speed wireless communication systems (e.g., long-term evolution (LTE), Wi-Fi) operate with high bandwidth and large peak-to-average power ratios (PAPRs). This is largely due to the use of orthogonal frequency division multiplexing (OFDM) modulation that is prevalent to maximize the spectral efficiency of the communication system. The power amplifier (PA) in the transmitter is the dominant energy consumer in the radio, largely because of the PAPR of the input signal. To reduce the energy consumption of the PA an amplifier that simultaneously achieves high efficiency and high linearity. Furthermore, to lower the cost for high volume production, it is desirable to achieve a complete System-on-Chip (SoC) integration. Linear amplifiers (e.g., Class-A, -B, -AB) are inefficient when amplifying signals with large PAPR that is associated by high peak-to-average modulation techniques such as LTE. OFDM. Switching amplifiers (e.g., Class-D, -E, -F) are very promising due to their high efficiency when compared to their linear amplifier counterparts. Linearization techniques for switching amplifiers have been intensively investigated due to their limited sensitivity to the input amplitude of the signal. Deep-submicron CMOS technology is mostly utilized for logic circuitry, and the Moore's law scaling of CMOS optimizes transistors to operate as high-speed and low-loss switches rather than high gain transistors. Hence, it is advantageous to use transistors in switching mode as switching amplifies and use high-speed digital logic circuitry to implement linearization systems and circuitry. In this work, several linearization architectures are investigated and demonstrated. An envelope elimination and restoration (EER) transmitter that comprises a class-E power amplifier and a 10-bit digital-to-analog converter (DAC) controlled current modulator is investigated. A pipelined switched-capacitor DAC is designed to control an open-loop transconductor that operates as a current modulator, modulating the amplitude of the current supplied to a class-E PA. Such a topology allows for increased filtering of the quantization noise that is problematic in most digital PAs (DPA). The proposed quadrature and multiphase architecture can avoid the bandwidth expansion and delay mismatch associated with polar PAs. The multiphase switched capacitor power amplifier (SCPA) was proposed after the quadrature SCPA and it significantly improves the power efficiency.

Diet and disease at Clyde's Cavern, Utah : as revealed Via Paleoscatology
Creators: name: Hall, Henry Johnson
Publisher: name: University of Utah
Year: 2019

description: Twenty coprolites recovered from the excavation of Clyde's Cavern, Utah, were examined for dietary components, dietary change through time, and evidence of parasites. The samples are representative of possibly three prehistoric cultures of Utah; Late Archaic (ca. 1120 B.C.-ca. A.D. 1, Levels 1 and 2), possibly Basket-maker Anasazi (BM II ? ca. A.D. 1 - ca. A.D. 475, Level 3), and Fremont (ca. A.D. 400-A.D. 1200, Levels 4 through 8). The small sample size from the earliest occupation levels (Levels 2 and 3) does not permit a generalization about the diet of this period. However, during Fremont occupation the only change in diet is the addition of corn and Indian rice grass. Corn, until Level 8, appears not as a staple but as a component of a composite diet of various seed types and non-seed plant material. Thus, the concept that the Fremont is but a horticultural accretion to Desert Archaic roots is not refuted (see Marwitt 1971). Throughout the human occupation of the cave the diet appears to reflect a pattern characteristic of the Desert Archaic lifeway. At least nine varieties of seeds were utilized together with non-seed plant material and small amounts of animal protein. The evidence of grit in all coprolites, and charcoal in most, suggests that some foods were roasted and milled before being ingested. Prehistoric man at Clyde's Cavern was heavily parasitized by the human pinworm. He may also have been parasitized by species of Strongyloides, and Acanthocephala. The methods of analysis were essentially those utilized by Fry (1970), however, certain modifications were made which added rigor and efficiency to the analysis.

From this theory, we derive a local field theory constructed of Yang--Mills fields and abelian antisymmetric and symmetric tensor fields of the second rank. The Chapline--Manton coupling, that is, coupling of Yang--Mills fields and a second-rank antisymmetric tensor field via the Chern--Simons 3-form is obtained in a systematic manner.

description: Textbooks in applied mathematics often use graphs to explain the meaning of formulae, even though their benefit is still not fully explored. To test processes underlying this assumed multimedia effect we collected performance scores, eye movements, and think-aloud protocols from students solving problems in vector calculus with and without graphs. Results showed no overall multimedia effect, but instead an effect to confirm statements that were accompanied by graphs, irrespective of whether these statements were true or false. Eye movement and verbal data shed light on this surprising finding. Students looked proportionally less at the text and the problem statement when a graph was present. Moreover, they experienced more mental effort with the graph, as indicated by more silent pauses in thinking aloud. Hence, students actively processed the graphs. This, however, was not sufficient. Further analysis revealed that the more students looked at the statement, the better they performed. Thus, in the multimedia condition the graph drew students' attention and cognitive capacities away from focusing on the statement. A good alternative strategy in the multimedia condition was to frequently look between graph and problem statement, and thus to integrate their information. In conclusion, graphs influence where students look and what they process, and may even mislead them into believing accompanying information. Thus, teachers and textbook designers should be very critical on when to use graphs and carefully consider how the graphs are integrated with other parts of the problem.

description: Electrochemical capacitors, or "supercapacitors", are an electrochemical energy storage technology with high-power density and long cycle life compared to batteries. Supercapacitors have many promising applications in electric vehicles, renewable energy storage, consumer electronics, environmental sensors, biomedical implants, and grid energy storage. Conductive polymers are a material of interest for supercapacitor energy storage because of their ability to store energy by both electric double layer capacitance and "pseudocapacitance" (surface reduction-oxidation reactions). Polypyrrole is a widely used conductive polymer for supercapacitor electrodes, as well as in lithium-ion batteries. For applications in environmental sensors, transient electronics, and implantable devices, it is necessary to find supercapacitor electrode materials that are easily biodegradable. A variation of polypyrrole exhibiting methyl carboxylate side chains, which we call "MPC polymer," is presented in this thesis as a dissolvable supercapacitor electrode. It is, to the best of our knowledge, introduced for the first time as a dissolvable electrochemical energy storage material. The supercapacitor characteristics of MPC polymer are characterized for planar electrodes as well as a nanocellulose-based composite. The MPC polymer is found to have capacitance, cycle life, and impedance characteristics comparable to state-of-the-art polypyrrole.

description: Designing and generating new data under targeted properties has been attracting various critical applications such as molecule design, image editing and speech synthesis. Traditional hand-crafted approaches heavily rely on expertise experience and intensive human efforts, yet still suffer from the insufficiency of scientific knowledge and low throughput to support effective and efficient data generation. Recently, the advancement of deep learning has created the opportunity for expressive methods to learn the underlying representation and properties of data. Such capability provides new ways of determining the mutual relationship between the structural patterns and functional properties of the data and leveraging such relationships to generate structural data, given the desired properties. This article is a systematic review that explains this promising research area, commonly known as controllable deep data generation. First, the article raises the potential challenges and provides preliminaries. Then the article formally defines controllable deep data generation, proposes a taxonomy on various techniques and summarizes the evaluation metrics in this specific domain. After that, the article introduces exciting applications of controllable deep data generation, experimentally analyzes and compares existing works. Finally, this article highlights the promising future directions of controllable deep data generation and identifies five potential challenges.

description: The present study investigated how parental experiences of direct and indirect minority stress are linked to mental health outcomes of the parent and LGB child, parenting styles, and other parental behaviors. A total of 223 parents with at least one LGB child participated in the study. Results showed that parental minority stress is associated with higher rates of mental health problems for parents and their LGB children, and were linked to higher rates of parental authoritarianism, less authoritativeness, less acceptance, and less conflict resolution between parent and child. Parental authoritarianism was found to mediate the link between direct parental minority stress and child mental health, as well as partially mediate the link between indirect parental minority stress and child mental health problems. These findings suggest that there are two different types of parental minority stress - one concerning the parents' own experiences of marginalization and one regarding their concerns for their LGB child - and that each form has meaningful implications on parental behavior and the psychological wellbeing of parents and their LGB children.

description: Acetylcholinesterase (AChE) is an important kind of esterase that plays a key biological role in the central and peripheral nervous systems. Recent research has demonstrated that some fullerene derivatives serve as a new nanoscale class of potent inhibitors of AChE, but the specific inhibition mechanism remains unclear. In the present article, several molecular modeling methods, such as molecular docking, molecular dynamics simulations and molecular mechanics/generalized Born surface area calculations, were used for the investigation of the binding mode and inhibition mechanism of fullerene inhibitions for AChE. Results revealed that fullerene inhibitors block the entrance of substrates by binding with the peripheral anionic site (PAS) region. Thus, fullerene derivatives might mainly serve as competitive inhibitors. The interactions of a fullerene backbone with AChE are at the same level in different single side chain systems and seem to be related to the length or aromaticity of the side chain. The inhibitor with multihydroxyl side chains shows an obviously large electrostatic interaction as it forms additional hydrogen bonds with AChE. Moreover, fullerene derivatives might exhibit noncompetitive inhibition partly by affecting some secondary structures around them. Thus, the destructions of these secondary structures can lead to conformational changes in some important regions, such as the catalytic triad and acyl pocket. The investigation is of great importance to the discovery of good fullerene inhibitors. Communicated by Ramaswamy H. Sarma

description: The NGC 5903 galaxy group is a nearby (~30 Mpc) system of ~30 members, dominated by the giant ellipticals NGC 5903 and NGC 5898. The group contains two unusual structures, a ~110 kpc long HI filament crossing NGC 5903, and a ~75 kpc wide diffuse, steep-spectrum radio source of unknown origin which overlaps NGC 5903 and appears to be partly enclosed by the HI filament. Using a combination of Chandra, XMM-Newton, GMRT and VLA observations, we detect a previously unknown ~0.65 keV intra-group medium filling the volume within 145 kpc of NGC 5903, and find a loop of enhanced X-ray emission extending ~35 kpc southwest from the galaxy, enclosing the brightest part of the radio source. The northern and eastern parts of this X-ray structure are also strongly correlated with the southern parts of the HI filament. We determine the spectral index of the bright radio emission to be $α_{150}^{612}$=1.03$\pm$0.08, indicating a radiative age >360 Myr. We discuss the origin of the correlated radio, X-ray and HI structures, either through an interaction-triggered AGN outburst with enthalpy 1.8x10$^{57}$ erg, or via a high-velocity collision between a galaxy and the HI filament. While neither scenario provides a complete explanation, we find that an AGN outburst is the most likely source of the principal X-ray and radio structures. However, it is clear that galaxy interactions continue to play an important role in the development of this relatively highly evolved galaxy group. We also resolve the question of whether the group member galaxy ESO 514-3 hosts a double-lobed radio source, confirming that the source is a superposed background AGN.

description: Scalable Solid-State Drives (SSDs) have ushered in a transformative era in data storage and accessibility, spanning both data centers and portable devices. However, the strides made in scaling this technology can bear significant environmental consequences. On a global scale, a notable portion of semiconductor manufacturing relies on electricity derived from coal and natural gas sources. A striking example of this is the manufacturing process for a single Gigabyte of Flash memory, which emits approximately 0.16 Kg of CO2 - a considerable fraction of the total carbon emissions attributed to the system. Remarkably, the manufacturing of storage devices alone contributed to an estimated 20 million metric tonnes of CO2 emissions in the year 2021.
 In light of these environmental concerns, this paper delves into an analysis of the sustainability trade-offs inherent in Solid-State Drives (SSDs) when compared to traditional Hard Disk Drives (HDDs). Moreover, this study proposes methodologies to gauge the embodied carbon costs associated with storage systems effectively. The research encompasses four key strategies to enhance the sustainability of storage systems. In summation, this paper critically addresses the embodied carbon issues associated with SSDs, comparing them with HDDs, and proposes a comprehensive framework of strategies to enhance the sustainability of storage systems.

Our revision detection system is designed for a large scale corpus and implemented in Apache Spark. We demonstrate that our system can more precisely detect revisions than state-of-the-art methods by utilizing the Wikipedia revision dumps https://snap.stanford.edu/data/wiki-meta.html and simulated data sets.
Discrimination against the negro in Utah and institutional efforts to eliminate it
Creators: name: Maag, Margaret Judy
Publisher: name: University of Utah
Year: 2019

description: This thesis is a look at the Negro in Utah, his history and his position from early settlement to the late 1960's. The Negro population in Utah increased steadily during most of this period, but it never became more than one-half of one percent of the total population of the state. The Negro population in Utah has been a quiet one, assuming the most menial of tasks and living in the poorest of conditions. It has also been a transient population, moving with jobs around Utah and into other states. The Negro community has been poorly organized because of its liquid nature and because of its poor conditions, both educationally and economically. In the 1960's it has become more organized, and following the national example, it has became more vocal in its opposition to some of the poor conditions existing in the state. The second focus of this thesis is on the actual discrimination encountered by the Negro as he functioned within the state. On a smaller scale most of the national discrimination, including Jim Crowism, existed in Utah through the years. The small number of Negroes excluded the practicability of segregated schools, or laws applying only to the Negro. Practice dictated a harsh discrimination in the field of public accommodations. The economic plight of the Negro was doubly bad -- he lacked the skills to obtain good jobs, and he was denied decent jobs if he obtained the skills. Legally, only one law, a harsh Anti-Miscegenation Law, existed on the state level. The role of the governments of the state has been one of neglect and disinterest in the situation of Negro citizen-so There have been few violent actions taken by white citizens against the Negro, but a background of threats and fear existed to an extent - at least to some Negro citizens. Finally the thesis looks at what has been done to end the discrimination existing within the state 0 A discussion is made of various groups, such as the National Association for the Advancement of Colored People and the Utah Citizens Organization for Civil Rights. These groups were effective in providing information, organization and pressure on the citizens of the state and the state legislature in gaining the passage of civil rights legislation. Two laws, a public accommodation law and a fair employment practices law, are the most spectacular results of these efforts. These laws were also encouraged by national currents and national laws, which forced Utah to enact such legislation, the last non-Southern state to do so. Another topic of importance is the relationship of the Negro and the Mormon (Latter-Day Saint) Church, which has controlled much of Utah's political, economic and cultural life. Utah, with the passive encouragement of this church, has often seemed racist in its attitudes toward and its treatment of its Negro citizens.

Through quantum control theory, we develop an analytical condition for achieving crosstalk-robust single-qubit control of multi-qubit systems. We examine the effects of quantum crosstalk via a cumulant expansion and develop a condition to suppress the leading order contributions to the dynamics. The efficacy of the condition is illustrated in the domains of quantum state preservation and noise characterization through the development of crosstalk-robust dynamical decoupling and quantum noise spectroscopy (QNS) protocols. Using the IBM Quantum Experience, crosstalk-robust state preservation is demonstrated on 27 qubits, where a $3\times$ improvement in coherence decay is observed for single-qubit product and multipartite entangled states. Through the use of noise injection, we experimentally demonstrate crosstalk-robust dephasing QNS on a seven qubit processor, where a $10^4$ improvement in reconstruction accuracy over ``cross-susceptible" alternatives is found. Together, these experiments highlight the significant impact the crosstalk mitigation condition can have on improving multi-qubit characterization and control on current quantum devices.

description: In this paper, we carry out a performance analysis from a probabilistic perspective to introduce the EDHVW methods' expected performances and limitations. Then, we propose a new general error diffusion based halftone visual watermarking (EDHVW) method, Content aware Double-sided Embedding Error Diffusion (CaDEED), via considering the expected watermark decoding performance with specific content of the cover images and watermark, different noise tolerance abilities of various cover image content and the different importance levels of every pixel (when being perceived) in the secret pattern (watermark). To demonstrate the effectiveness of CaDEED, we propose CaDEED with expectation constraint (CaDEED-EC) and CaDEED-NVF&IF (CaDEED-N&I). Specifically, we build CaDEED-EC by only considering the expected performances of specific cover images and watermark. By adopting the noise visibility function (NVF) and proposing the importance factor (IF) to assign weights to every embedding location and watermark pixel, respectively, we build the specific method CaDEED-N&I. In the experiments, we select the optimal parameters for NVF and IF via extensive experiments. In both the numerical and visual comparisons, the experimental results demonstrate the superiority of our proposed work.

description: Mass, metallicity, and star formation rate (SFR) of a galaxy are crucial parameters in understanding galaxy formation and evolution. However, the relation among these is still a matter of debate for luminous infrared galaxies, which carry a bulk of SFR budget of the universe at $z\sim1$. We have investigated the relation among stellar mass, gas-phase oxygen abundance, and SFR of AKARI-detected mid-IR galaxies at $z\sim0.88$ in the AKARI NEP deep field. We observed about 350 AKARI sources with Subaru/FMOS NIR spectrograph, and detected secure and expected H$α$ emission lines from 25 and 44 galaxies, respectively. The SFR of our sample is almost constant ($\sim 25M_{\odot}/yr$) over the stellar mass range of our sample. Compared with main-sequence (MS) galaxies at a similar redshift range, the average SFR of our detected sample is comparable for massive galaxies ($\sim10^{10.58}~M_{\odot}$), while higher by $\sim$0.6dex for less massive galaxies ($\sim 10^{10.05}~M_{\odot}$). We measure metallicities from the [NII]/H$α$ emission line ratio. We find that the mass-metallicity relation of our individually measured sources agrees with that for optical-selected star-forming galaxies at $z\sim0.1$, while metallicities of stacked spectra agree with that of MS galaxies at $z\sim0.78$. Considering high SFR of individually measured sources, FMR of the IR galaxies is different from that at $z\sim0.1$. However, on the mass-metallicity plane, they are consistent with the MS galaxies, highlighting higher SFR of the IR galaxies. This suggests the evolutionary path of our IR galaxies is different from that of MS galaxies. A possible physical interpretation includes that the star-formation activities of IR galaxies at $z\sim0.88$ in our sample are enhanced by interaction and/or merger of galaxies, but the inflow of metal-poor gas is not yet induced, keeping the metallicity intact.

Radio-quiet neutron star 1E 1207.4-5209: a possible strong Gravitational-wave source

description: There are four puzzles on 1E 1207.4-5209: (1) the characteristic age of the pulsar is much higher than the estimated age of the supernova remnant; (2) the magnetic field inferred from spin-down is significantly different from the value obtained from the cyclotron absorption lines; (3) the spinning down of the pulsar is non-monotonic; (4) the magnitude of the frequency's first derivative varies significantly and its sign is also variable. The third puzzle can be explained by a wide binary system, with orbital period from 0.2 to 6 yr. This letter proposes that all four puzzles can be explained naturally by an ultra-compact binary with orbital period of between 0.5 and 3.3 min. With the shortest orbital period and a close distance of 2 kpc, the characteristic amplitude of gravitational waves is $h\sim3\times10^{-21}$. It would be an excellent source of gravitational-wave detectors such as the Laser Interferometer Space Antenna.

Diana's Confession: Precarious Rhetoric in Post-NAFTA Mexico

description: In August of 2013, Roberto Flores and Alfredo Zárate, two Ciudad Juárez bus drivers, were killed while working. The murderer, according to eyewitnesses, was a woman between 30 and 50 years old. She purportedly wore a blonde wig and a baseball cap to conceal her identity. Eyewitnesses also told investigators that the murderer made remarks before killing the bus drivers, such as "you think you're so bad?" Ciudad Juárez was once considered the murder capital of the world, so the news of two more murders was hardly "news." Thus, this dissertation presents a case that demonstrates the normalization of quotidian violence-a process achieved through everyday cultural acts. Days after the murders, local news media received a confession. The author, who called herself Diana la Cazadora de Choferes (Diana, the hunter of bus drivers), claimed that she had vengefully murdered the bus drivers in response to the raped and murdered female maquiladora workers of Ciudad Juárez. This confession brought together a variety of discourses about maquiladora labor in Mexico, feminicidios (the unsolved murders of women in Ciudad Juárez), organized crime, and governmental impunity. From a rhetorical perspective, this confession also hinted at discourses of rhetorical agency, social movements, the rhetorical construction of truth and credulity, and the role of mythology within modernity. Throughout this dissertation, I take a variety of critical, cultural, and rhetorical approaches as I construct and contextualize "Diana," following McGee's (1990) fragmentation theory. McGee argues that "rhetors make discourses from scraps and pieces of evidence. Critical rhetoric [as opposed to rhetorical criticism] does not begin with a finished text in need of interpretation; rather, texts are understood to be larger than the apparently finished discourse that presents itself as transparent" (p. 279). Thus, in this dissertation I examine several scraps of discourse that together, point toward one rhetorical construction of Diana la Cazadora de Choferes-not a complete or finished construction, but one that is put forth toward a specific telos: the illustration of what I term retórica moribunda, precarious rhetorics of life and death in contemporary Mexico.

description: Predictions and forecasts of machine learning models should take the form of probability distributions, aiming to increase the quantity of information communicated to end users. Although applications of probabilistic prediction and forecasting with machine learning models in academia and industry are becoming more frequent, related concepts and methods have not been formalized and structured under a holistic view of the entire field. Here, we review the topic of predictive uncertainty estimation with machine learning algorithms, as well as the related metrics (consistent scoring functions and proper scoring rules) for assessing probabilistic predictions. The review covers a time period spanning from the introduction of early statistical (linear regression and time series models, based on Bayesian statistics or quantile regression) to recent machine learning algorithms (including generalized additive models for location, scale and shape, random forests, boosting and deep learning algorithms) that are more flexible by nature. The review of the progress in the field, expedites our understanding on how to develop new algorithms tailored to users' needs, since the latest advancements are based on some fundamental concepts applied to more complex algorithms. We conclude by classifying the material and discussing challenges that are becoming a hot topic of research.

description: We study the relations between a generalization of pseudocompactness, named $(κ, M)$-pseudocompactness, the countably compactness of subspaces of $βω$ and the pseudocompactness of their hyperspaces. We show, by assuming the existence of $\mathfrak c$-many selective ultrafilters, that there exists a subspace of $βω$ that is $(κ, ω^*)$-pseudocompact for all $κ
