Improving Real Estate Rental Estimations with Visual Data

Multi-modal data are widely available for online real estate listings. Announcements can contain various forms of data, including visual data and unstructured textual descriptions. Nonetheless, many traditional real estate pricing models rely solely on well-structured tabular features. This work investigates whether it is possible to improve the performance of the pricing model using additional unstructured data, namely images of the property and satellite images. We compare four models based on the type of input data they use: (1) tabular data only, (2) tabular data and property images, (3) tabular data and satellite images, and (4) tabular data and a combination of property and satellite images. In a supervised context, the branches of dedicated neural networks for each data type are fused (concatenated) to predict log rental prices. The novel dataset devised for the study (SRED) consists of 11,105 flat rentals advertised over the internet in Switzerland. The results reveal that using all three sources of data generally outperforms machine learning models built on only tabular information. The findings pave the way for further research on integrating other non-structured inputs, for instance, the textual descriptions of properties.
Modulated Dual-Voltage-Vector Model-Free Predictive Current Controller for Synchronous Reluctance Motor Drives With Online Duty Cycle Calculation

In this paper, a modulated dual-voltage-vector model-free predictive current control with online duty cycle calculation is proposed and applied to drive a synchronous reluctance motor. The dual-voltage-vector modulation scheme reduces the current ripples and errors in the single-voltage-vector method. The proposed method reduces the predictive current controller’s calculation time by first setting the initial value of the duty cycle to a constant. Then, an optimal switching mode can be selected by minimizing a cost function. Next, the required duty cycle can be calculated directly by the proposed method without any differential calculations instead of its initial value. The proposed method can effectively track the stator current, reducing the maximum average current error by 34.8% compared to the conventional single-voltage-vector scheme. Finally, the correctness and feasibility of the modulated model-free predictive current controller with the online duty cycle calculation proposed in this article are verified by the experimental results using Texas Instruments microcontroller TMS320F28379D.
Quelle surveillance des patients traités par opioïdes dans les unités de soins conventionnels ? Revue de la littérature, alerte et mise au point du CAMR, de la SFAR et de la SFETD

Risques de dépression respiratoire postopératoire liés aux opioïdes : 1) tout patient bénéficiant en postopératoire d’un traitement par opioïde est à risque de dépression respiratoire quelle que soit la voie d’administration ; 2) la littérature rapporte que la dépression respiratoire survient majoritairement dans les 12 heures postopératoires, la nuit (entre minuit et 6 h) et entraîne généralement le décès du patient ou une encéphalopathie postanoxique ; 3) les facteurs de risque de dépression respiratoire sont connus (liés au patient, au type de chirurgie et aux modalités d’administration) et doivent être recherchés dès la consultation préanesthésique ; 4) des scores prédictifs de dépression respiratoire existent et ont été validés sur de grandes séries publiées ; 5) l’administration continue d’oxygène est une fausse sécurité, pouvant même retarder le diagnostic. Modalités de surveillance postopératoire des patients bénéficiant d’opioïdes : 1) la surveillance clinique seule est insuffisante chez les patients à risque ; 2) une surveillance paraclinique (avec SpO2 et capnographie) est efficace chez les patients à risque ; 3) de nombreux systèmes de surveillance continue électronique (utilisant SpO2, capnographie, impédancemétrie et/ou pléthysmographie) existent, mais ne peuvent être recommandés actuellement en pratique courante du fait de leur ergonomie, de leur coût, de leurs nombreux artefacts et des faux-positifs. Leur développement semble être la solution d’avenir ; 4) l’hospitalisation en postopératoire des sujets à risque en unité de soins continus (pendant 24 heures) reste la seule alternative fiable pour prévenir ce risque.
Simultaneous Bandwidth-Extended and Precisely-Gain-Controlled dB-Linear PGA Based on Active Feedback and Binary-Weighted Switches

A simple yet effective approach for programmable gain amplifier (PGA) with a high precision decibel (dB)-linear characteristic and wide bandwidth is presented in this brief. This novel approach is presented by innovatively combining two techniques. Based on the binary-weighted switching technique, the circuit can approach an accurate pseudo-exponential function without using an additional exponential generator for gain control. By adopting the active feedback circuit structure, the bandwidth of PGA can be extended and it also contributes to improve the robustness, both of which cleverly reached a good consistency. The proposed PGA is fabricated in a <inline-formula> <tex-math notation="LaTeX">$0.18~{\mu }\text{m}$ </tex-math></inline-formula> CMOS technology, the core circuit occupies an area of 0.11 mm2. Operated at a supply voltage of 1.8 V, the PGA consumes 8.21 mW. The measurement results show that the voltage gain of the proposed PGA can be controlled from −4.2 dB to 25.9 dB with a gain error less than ±0.09 dB, and the minimum −3dB bandwidth is almost 630 MHz. The input 1dB compression point is measured from −28.7 to 0.5 dBm, while the input referred noise is from 22.4 to 70.9 nV/<inline-formula> <tex-math notation="LaTeX">${{\sqrt {}}}$ </tex-math></inline-formula>Hz.
Predicting the closed-loop stability and oscillation amplitude of nonlinear parametrically amplified oscillators

This work investigates the closed-loop operation of microelectromechanical oscillators in the presence of both cubic (Duffing) nonlinearities and parametric amplification. We present a theoretical model for this system that enables us to predict oscillation amplitude and instability and experimentally verify it using a silicon disk resonator with a quality factor (Q) of 85 000 and a natural frequency of 251 kHz. We determine that, contrary to previous understanding gained from analyzing the open-loop system, the presence of cubic nonlinearities does not limit the maximum stable oscillation amplitude if the resonator is operated in a closed loop. In addition, the stability and amplitude behavior predicted by our theoretical model are independent of the presence or severity of cubic nonlinearities, or on drive amplitude.
Direct Frequency Comb Spectroscopy for Optical Frequency Metrology and Coherent Interactions

Date The final copy of this thesis has been examined by the signatories, and we find that both the content and the form meet acceptable presentation standards of scholarly work in the above mentioned discipline. Interactions Thesis directed by Dr. Jun Ye We take advantage of a phase-stable, wide-bandwidth femtosecond laser to bridge the fields of high-resolution spectroscopy and ultrafast science. This approach, which we call Direct Frequency Comb Spectroscopy (DFCS), involves using light from a comb of appropriate structure to directly interrogate atomic levels and to study time-dependent quantum coherence. In fact, DFCS may be effectively applied to determine absolute frequencies for atomic transitions anywhere within the comb bandwidth, obviating the need for broadly tunable and absolutely referenced continuous-wave (cw) lasers. In this work, we apply DFCS to determine absolute atomic transition frequencies for one-and two-photon processes in laser-cooled 87 Rb atoms. In addition, DFCS enables studies of coherent pulse accumulation and multipulse interference, permitted by the relatively long-lived excited states. These effects are well modeled by our density matrix theory describing the interaction of the femtosecond comb with the cold atoms. As in the case of precision spectroscopy performed with cw lasers, the use of the femtosecond comb as a probe requires a careful understanding of all systematic effects. We isolate and then mitigate the effects of the dominant sources of systematic errors, which include the mechanical effect of the optical comb on the atomic motion, Stark shifts by the probe laser, and Zeeman frequency shifts. The absolute frequency measurement results are comparable to the highest resolution measurements made with cw lasers. In addition, by determining the previously unmeasured absolute frequency of the 5S-7S two-photon transitions in 87 Rb, we show that prior knowledge of atomic transition frequencies is not essential for DFCS. Acknowledgements I would like to offer my gratitude to the people who have made my time here at JILA profitable and interesting. There are many people who have helped along the way and I hope I have included all of them below. Special thanks are due to my advisor Jun Ye who gave me the opportunity to work on a very new and challenging experiment. Under his guidance I have learned about cold Rb, laser stabilization, mode-locked lasers and integrating cutting edge techniques to probe new physics. I would especially like to thank the people who worked closely with me on the Rb project within …
Nurses’ Perspectives on Smoking Policies, Safety and Cessation Support in Psychiatric Wards: A Cross-Sectional Survey

A high prevalence of smoking and low rates of smoking cessation interventions can be observed in psychiatric wards. A questionnaire-based, cross-sectional study was performed in five hospitals among 107 psychiatric ward nurses. The aim was to investigate nurses’ views on patients’ smoking practices and their influence on the safety of both the patients and medical personnel. In addition, we asked about the availability of smoking cessation support. Most of the respondents noticed the negative impacts of smoking on patients and medical personnel. Nearly a third of our respondents (29.0%) recalled smoking-related accidents in their facilities. In 45.2% of these accidents, a patient set someone else on fire. Around one fifth of nurses had rather permissive attitudes towards tobacco use in hospital wards. Significant associations were identified between respondents’ smoking status and their opinions on amending smoking policies and on unsupervised smoking. Regarding professional help available to smoking patients, 88.8% of participants reported that interventions to address smoking were available in their wards. Psychiatric hospitalisation can be an opportunity to offer tobacco treatment to patients with mental health conditions. To make use of this opportunity, smoke-free policies need to be put in place and hospital personnel, particularly nurses, should be trained and equipped with the knowledge and skills needed to assist in the smoking care of psychiatric ward patients.

Identification and Quantitation of Novel ABI3 Isoforms Relative to Alzheimer’s Disease Genetics and Neuropathology

Elucidating the actions of genetic polymorphisms associated with the risk of Alzheimer’s disease (AD) may provide novel insights into underlying mechanisms. Two polymorphisms have implicated ABI3 as a modulator of AD risk. Here, we sought to identify ABI3 isoforms expressed in human AD and non-AD brain, quantify the more abundant isoforms as a function of AD genetics and neuropathology, and provide an initial in vitro characterization of the proteins produced by these novel isoforms. We report that ABI3 expression is increased with AD neuropathology but not associated with AD genetics. Single-cell RNAseq of APP/PS1 mice showed that Abi3 is primarily expressed by microglia, including disease-associated microglia. In human brain, several novel ABI3 isoforms were identified, including isoforms with partial or complete loss of exon 6. Expression of these isoforms correlated tightly with total ABI3 expression but were not influenced by AD genetics. Lastly, we performed an initial characterization of these isoforms in transfected cells and found that, while full-length ABI3 was expressed in a dispersed punctate fashion within the cytosol, isoforms lacking most or all of exon six tended to form extensive protein aggregates. In summary, ABI3 expression is restricted to microglia, is increased with Alzheimer’s neuropathology, and includes several isoforms that display a variable tendency to aggregate when expressed in vitro.

This paper is a review on distributed optic fiber sensing for structural health monitoring applications, with a deeper focus on technologies relying on the Rayleigh backscattering phenomenon. It addresses the basic physical principles which are involved, the implementation and instrumentation of the measurement techniques, as well as recent practical applications, current performance, and remaining challenges. Being written at an elementary level and integrating relevant theoretical and technical details, we hope the document can be useful for researchers and engineers looking for an up-to-date overview on a field which currently undergoes significant development and increasing attractiveness, in particular for damage tracking in complex mechanical structures.
Protection against Paraquat-Induced Oxidative Stress by Curcuma longa Extract-Loaded Polymeric Nanoparticles in Zebrafish Embryos

The link between oxidative stress and environmental factors plays an important role in chronic degenerative diseases; therefore, exogenous antioxidants could be an effective alternative to combat disease progression and/or most significant symptoms. Curcuma longa L. (CL), commonly known as turmeric, is mostly composed of curcumin, a multivalent molecule described as having antioxidant, anti-inflammatory and neuroprotective properties. Poor chemical stability and low oral bioavailability and, consequently, poor absorption, rapid metabolism, and limited tissue distribution are major restrictions to its applicability. The advent of nanotechnology, by combining nanosacale with multi-functionality and bioavailability improvement, offers an opportunity to overcome these limitations. Therefore, in this work, poly-Ɛ-caprolactone (PCL) nanoparticles were developed to incorporate the methanolic extract of CL, and their bioactivity was assessed in comparison to free or encapsulated curcumin. Their toxicity was evaluated using zebrafish embryos by applying the Fish Embryo Acute Toxicity test, following recommended OECD guidelines. The protective effect against paraquat-induced oxidative damage of CL extract, free or encapsulated in PCL nanoparticles, was evaluated. This herbicide is known to cause oxidative damage and greatly affect neuromotor functions. The overall results indicate that CL-loaded PCL nanoparticles have an interesting protective capacity against paraquat-induced damage, particularly in neuromuscular development that goes well beyond that of CL extract itself and other known antioxidants.
THE INFLUENCE OF MINING IN THE QUADRILÁTERO FERRÍFERO: LANDSCAPE SPATIAL-TEMPORAL DYNAMICS

The Quadrilátero Ferrífero – QF is the main producer/explorer of iron ore in Brazil, occupying the worldwide leadership group in Mineral Exploration. Considering all the environmental impacts associated with this activity, it is necessary to assess the landscape patterns to support the sustainable planning of mining companies. So, this paper aimed to define the temporal changes in the QF landscape's configuration and composition from 1985 to 2018 and predict 2053. The research was carried out in the QF region, located in Minas Gerais, Brazil. We used classified images of land use/cover from 1985 to 2018 to calculate the landscape metrics and perform the Land Change Modeler tool. Thus, we obtained the landscape patterns over the years and a prediction for 2053. To that content, we used class and landscape metric levels, especially to describe the spatial distribution of land use/cover, and to identify how its composition has changed over the years. The results show that the Forest class contributed the most to Mining, with +0.09% in the area. In addition, the Farming class decreased 12%, with its total area converted among the others land use/cover. Thus, the Forest and Mining patches’ areas raised by 4% and 0.2%, with a tendency for a continuous increase until 2053. However, the forest fragments tended to disaggregate, while the Mining areas tended to become more connected. These results converge to a worrying scenario from an ecological point of view. Therefore, it is necessary to have/search for better supervision related to the compliance of environmental laws to avoid biodiversity losses in mining areas.
Loop Quantum Cosmology: Effective Theory and Related Applications

The effort toward making quantum mechanics and general relativity compatible (quantum gravity) has lasted more than a century. The string theory and loop quantum gravity both stand out as strong candidates and currently they both make popular research subjects in quantum gravity. As we known, Loop quantum gravity (LQG)(Ashtekar & Lewandowski, 2004; Rovelli, 1998; 2004; Thiemann, 2007) is a background independent and non-perturbative canonical quantum gravity theory. LQG has made many breakthroughs in recent years: the establishment of the quantum Einstein equations Ashtekar & Tate (1994); Ashtekar et al. (1995a); Corichi & Zapata (1997); Lewandowshi & Thiemann (1999); Rovelli & Smolin (1994); Thiemann (1996; 1998a;b;c; 2001), the proof that the Riemannian operators have discrete eigenvalues Ashtekar et al. (1995b); Lewandowski (1997); Loll (1995a;b; 1997a;b); Rovilli & Smolin (1995); Thiemann (1998d;e),results concerning the entropy of the black hole horizon and cosmological horizon entropy with statistical mechanics Ashtekar et al. (1998; 1999; 2000; 2001; 2002; 2003a;b); Berreira et al. (1996); Rovelli (1996a;b); Smolin (1995), and so on. As an application of loop quantum gravity to cosmology, loop quantum cosmology (LQC) Bojowald (2005a; 2008); Date (2002) also presents itself as a possible path toward answers to the cosmological and astrophysical riddles. As a symmetry reduced model of LQG, LQC inherits the quantum schemes originated from LQG that dealt with the isotropic and homogeneous universe firstly and then extended to the inhomogeneous and anisotropic model Bojowald (2002a). It plays an important role in connecting the LQG theory and the measureable world. On one hand, it is used to test the full theory, which, in its own form, is extremely complex and difficult to directly apply.On the other hand, making connections to the real world sheds light on further improvement of the LQG theory. These reasons make LQC a promising and enlightening subject to study. In LQC, the collapsing and expanding phases are connected by the cyclic or oscillatorymodels Lidsey et al. (2004), and the universe is automatically born with a small scale factor at the fixed point near the Planck phase Bojowald (2005); Mulryne et al. (2005a). Unlike in the emergent universe model, this fixed point here is stable and allows the universe to start in an initial phase of oscillation. Then an inflationary phase is entered, which is the relevant regime for structure formation. In LQC, there aremany different inflationary scenarios Artymowski et al. (2009); Bojowald et al. (2004); Mulryne et al. (2005b); Zhang & Ling (2007), among which the one without inflation is the most attractive, mainly because it can explain the inflationary phase directly from LQG. But, unfortunately, it is difficult to study the structure formation. 16

Relationship between Behavioural Empowerment and Employee Commitment in selected Star Rated Hotels in Kisumu City, Kenya

Purpose: The objective of this study was to determine the relationship between behavioural empowerment and employee commitment in selected star-rated Hotels in Kisumu City, Kenya. This study was anchored on Social Cognitive Theory. Methodology: The study adopted explanatory and descriptive research designs. The target population was 1372 non-managerial employees and 130 managerial employees from 34 star rated hotels. A sample size of 310 non-managerial employees and 13 management staff formed the sample for the study. The respondents were selected using stratified and simple random sampling techniques. Questionnaires and interview schedule were used to collect data. The validity of the surveys was established using professional judgment. The dependability of the research tool was assessed using Cronbach's Alpha Coefficient. Both descriptive and inferential statistics were used to analyze the data. Mean, frequencies, and standard deviation were included in descriptive statistics, whereas linear regression was part of inferential statistics and data presented using tables. Findings: According to the study's findings, employee commitment and behavioral empowerment were significantly positively correlated in a few star-rated hotels (1=0.751; p0.05). Unique Contribution to theory, practice and policy: The study came to the conclusion that, in particular hotels, behavioural empowerment had a substantial impact on employees' engagement. Encourage hotel staff to have confidence in their sense of judgment, values, work roles, and actions related to their jobs.
North-East Asian Super Grid: Renewable energy mix and economics

Further development of the North-East Asian energy system is at a crossroads due to severe limitations of the current conventional energy based system. For North-East Asia it is proposed that the excellent solar and wind resources of the Gobi desert could enable the transformation towards a 100% renewable energy system. An hourly resolved model describes an energy system for North-East Asia, subdivided into 14 regions interconnected by high voltage direct current (HVDC) transmission grids. Simulations are made for highly centralized, decentralized and country-wide grids scenarios. The results for total system levelized cost of electricity (LCOE) are 0.065 and 0.081 €/(kW·h) for the centralized and decentralized approaches for 2030 assumptions. The presented results for 100% renewable resources-based energy systems are lower in LCOE by about 30–40% than recent findings in Europe for conventional alternatives. This research clearly indicates that a 100% renewable resources-based energy system is THE real policy option.
