Full-text available
The subleasing of rooms is a widespread reality in large urban areas, however, the absence of statistics in this regard makes its analysis difficult. A large part of the immigrant population has access to a dwelling through this modality. Therefore, in this study, 27 semi-structured interviews are analyzed to evaluate the role of subleasing in the...

A partial left frontal (UCM 55499) of a small tyrannosaurid theropod from the Campanian Two Medicine Formation of Montana is described, and is considered to probably represent a juvenile of Daspletosaurus horneri. UCM 55499 compares favorably with the frontals of other young juvenile tyrannosaurid specimens, and its diminutive size suggests that th...

The information systems field has a long-standing interest in how individual actions co-evolve with social structures. Yet, studying the exact process of co-evolution turned out to be elusive. We propose a novel way to study this co-evolution using digital trace data. By analyzing the sequences of individual actions through digital trace data and t...

In this study, an investigation is conducted into the phenomenon of price clustering in Bitcoin (BTC) denominated in the Japanese yen (JPY). It answers two questions using tick-by-tick data. The first is whether price clustering exists in BTC/JPY transactions, and the other is how the scale of price clustering varies throughout a trading day. With...

We discover three-dimensional intertwined Weyl phases, by developing a theory to create topological phases. The theory is based on intertwining existing topological gapped and gapless phases protected by the same crystalline symmetry. The intertwined Weyl phases feature both unconventional Weyl semimetallic (monopole charge>1) and higher-order topo...

This paper explored differences in youth life satisfaction across and within countries during the COVID-19 pandemic. A central finding was the flattening, or even the reversal, of the U-shaped age pattern in life satisfaction in some countries. Life satisfaction declined to a greater extent among youth aged 15 to 30 years than among people aged 31...

The method of the learning of vague languages which represent distorted/ambiguous patterns is proposed in the paper. The goal of the method is to infer the quasi-context-sensitive string grammar which is used in our model as the generator of patterns. The method is an important component of the multi-derivational model of the parsing of vague langu...

Matsuda et al. (2022) show that late bloomers also exist in self-report data. They use a “dynamic” definition of late bloomer offending pattern as they have concerns with definitions based on arbitrary age cutoff points. But the approach does not make the groups less arbitrary than hard definitions. In this commentary, I argue that a hard definitio...

Event logs, as viewed in process mining, contain event data describing the execution of operational processes. Most process mining techniques take an event log as input and generate insights about the underlying process by analyzing the data provided. Consequently, handling large volumes of event data is essential to apply process mining successful...

It may happen that under a certain wave interrogation, a medium scatterer produces no scattering. In such a case, the scattering field is trapped inside the scatterer and forms a certain interior resonant mode. We are concerned with the behavior of the wave propagation inside a transparent scatterer. It turns out that the study can be boiled down t...

By means of a Darboux transform with particular generating function solutions to the Kadomtsev–Petviashvili equation (KPI) are constructed. We give a method that provides different types of solutions in terms of particular determinants of order N. For any order, these solutions depend of the degree of summation and the degree of derivation of the g...

Inequalities play a fundamental role in both theoretical and applied mathematics and contain many patterns of symmetries. In many studies, inequalities have been used to provide estimates of some functions based on the properties of their symmetry. In this paper, we present the following new asymptotic expansion related to the ordinary gamma functi...

Droplets coalescing on flat surfaces tend to end up with the smaller droplet migrating into the larger one. We report a counter-intuitive droplet coalescence pattern on a superhydrophilic cylindrical wire, where the larger droplet is pulled toward the smaller one. Consequently, the center of the combined mass significantly moves toward, often beyon...

The collapsibility number of simplicial complexes was introduced by Wegner in order to understand the intersection patterns of convex sets. This number also plays an important role in a variety of Helly type results. There are only a few upper bounds for the collapsibility number of complexes available in literature. In general, it is difficult to...

The paper [1] presented the first results on generic identifiability of dynamic networks with partial excitation and partial measurements, i.e. networks where not all nodes are excited or not all nodes are measured. One key contribution of that paper was to establish a set of necessary conditions on the excitation and measurement pattern (EMP) that...

The ability to learn sequences depends on different factors, such as transitional probability (TP, probability of a stimulus given a previous stimulus) and dependency (adjacent or nonadjacent stimuli in a sequence). Current evidence indicates differences in learnability of adjacent and nonadjacent pairs as well as of first-order and second-order TP...

As institutions seek to increase their capacity in various modes and models of instruction, they are relying more heavily on learning designers to implement these projects. This has created a need to scale-up beyond the artisanal approaches and practices of traditional learning design. This presentation will explore the development of collaborative...

It is still unknown whether the mass terms for neutrinos are of Majorana type or of Dirac type. An interesting possibility, known as pseudo-Dirac scheme combines these two with a dominant Dirac mass term and a subdominant Majorana one. As a result, the mass eigenstates come in pairs with a maximal mixing and a small splitting determined by the Majo...

This contribution investigates the MM III building complex at Alonaki at the foot of Mt Juktas (Crete) with emphasis on patterns of pottery production and consumption. The evidence of the pottery shows that the bulk of the assemblage should be placed chronologically in the mature MM IIIA period and that the building was destroyed at the end of the...

Abstract Managing patients who are aggressive and violent is a challenging task for staff of psychiatric hospitals. Physical or chemical restraint is resorted to when verbal counseling does not help in de-escalation. It is often believed that restraint is very often overused in psychiatric hospitals. In the Indian clinical settings there is no dat...

With very few exceptions, the large amount of available experimental bounds on heavy neutral leptons – HNL – have been derived relying on the assumption of the existence of a single (usually Majorana) sterile fermion state that mixes with only one lepton flavour. However, most of the extensions of the Standard Model involving sterile fermions predi...

A broadband radiation dual‐polarized antenna is proposed for the application of 5G sub‐6 GHz base stations. The radiator of the antenna is consisted of a pair of crisscrossed sector dipoles, and is fed by microstrip stubs. By etching rectangular slots on the patches, the resonant modes of the antenna can increase to eight. Therefore, the broadband...
