Development of Machine Learning Model for Prediction of Demolition Waste Generation Rate of Buildings in Redevelopment Areas

Owing to a rapid increase in waste, waste management has become essential, for which waste generation (WG) information has been effectively utilized. Various studies have recently focused on the development of reliable predictive models by applying artificial intelligence to the construction and prediction of WG information. In this study, research was conducted on the development of machine learning (ML) models for predicting the demolition waste generation rate (DWGR) of buildings in redevelopment areas in South Korea. Various ML algorithms (i.e., artificial neural network (ANN), K-nearest neighbors (KNN), linear regression (LR), random forest (RF), and support vector machine (SVM)) were applied to the development of an optimal predictive model, and the main hyper parameters (HPs) for each algorithm were optimized. The results suggest that ANN-ReLu (coefficient of determination (R2) 0.900, the ratio of percent deviation (RPD) 3.16), SVM-polynomial (R2 0.889, RPD 3.00), and ANN-logistic (R2 0.883, RPD 2.92) are the best ML models for predicting the DWGR. They showed average errors of 7.3%, 7.4%, and 7.5%, respectively, compared to the average observed values, confirming the accurate predictive performance, and in the uncertainty analysis, the d-factor of the models appeared less than 1, showing that the presented models are reliable. Through a comparison with ML algorithms and HPs applied in previous related studies, the results herein also showed that the selection of various ML algorithms and HPs is important in developing optimal ML models for WG management.
Statistics of resonance poles, phase shifts and time delays in quantum chaotic scattering: Random matrix approach for systems with broken time-reversal invariance

Assuming the validity of random matrices for describing the statistics of a closed chaotic quantum system, we study analytically some statistical properties of the S-matrix characterizing scattering in its open counterpart. In the first part of the paper we attempt to expose systematically ideas underlying the so-called stochastic (Heidelberg) approach to chaotic quantum scattering. Then we concentrate on systems with broken time-reversal invariance coupled to continua via Mopen channels; a=1,2,…,M. A physical realization of this case corresponds to the chaotic scattering in ballistic microstructures pierced by a strong enough magnetic flux. By using the supersymmetry method we derive an explicit expression for the density of S-matrix poles (resonances) in the complex energy plane. When all scattering channels are considered to be equivalent our expression describes a crossover from the χ2 distribution of resonance widths (regime of isolated resonances) to a broad power-like distribution typical for the r.
Modeling and Design of a Mechanical Tendon Actuation System

Basic dynamics of single tendons are modeled, isolated, and measured. Fundamental transmission line models are presented with assumptions applicable to using the models for tendons. The models are verified by careful experimental design. It is then shown how to use this fundamental data to design and determine bandwidth limitations of tendon actuation systems. Short, stiff, light tendons transmit force and velocily best. Pulley friction in the tests reported was primarily Coulombic, causing signal delay
Final voicing and devoicing in American English

English is typically described as a language in which voicing contrast is not neutralized in word-final position. However, a tendency towards devoicing (at least partial) of final voiced obstruents in English has been reported by the previous studies (e.g., Docherty (1992) and references therein). In the present study, we examine a number of acoustic correlates of obstruent voicing and the robustness with which each one is able to differentiate between voiced and voiceless obstruents in the word-final position in the speech recorded by twenty native speakers of the Mid-Western dialect of American English. The examined acoustic properties include preceding vowel duration, closure or frication duration, duration of the release portion, and duration of voicing during the obstruent closure, frication, and release. Initial results indicate that final voiced obstruents are significantly different from the voiceless ones in terms of preceding vowel duration and closure/frication duration. However, release durati.
Usefulness of High-Sensitivity Troponin I in Risk Stratification and Final Disposition of Patients with Acute Heart Failure in the Emergency Department: Comparison between HFpEF vs. HFrEF

Background and Objectives: In patients with acute heart failure (AHF), there is no definite evidence on the relationship between high-sensitivity cardiac troponin (hs-cTnI) and the left ventricular ejection fraction (LVEF) comparing the reduced and preserved EF conditions. Materials and Methods: Between January and April 2022, we retrospectively analyzed the data from 386 patients admitted to the emergency departments (ED) of five hospitals in Rome, Italy, for AHF. The criteria for inclusion were a final diagnosis of AHF; a cardiac ultrasound and hs-cTnI evaluations in the ED; and age > 18 yrs. We excluded patients with acute coronary syndrome (ACS). Based on echocardiography and hs-cTnI evaluations, the patients were grouped for (1) preserved (HFpEF) or (2) reduced LVEF (HFrEF) and a a) negative (within the normal range value) or b) positive (above the normal range value) of hs-cTnI, respectively. Results: There was a significant negative relationship between a positive test for hs-cTnI and LVEF. When compared to the group with a negative hs-cTnI test, the patients with a positive test, both from the HFpEF and HFrEF subgroups, were significantly more likely to have an adverse outcome, such as being admitted to the intensive care unit (ICU) or dying in the ED. Moreover, a reduced ejection fraction was linked with a final disposition to a higher level of care. Conclusions: In patients admitted to the ED for AHF without ACS, there is a negative relationship between hs-cTnI and a reduced LVEF, although a significant percentage of patients with a preserved LVEF also resulted to have high levels of hs-cTnI. In the absence of ACS, hs-cTnI seems to be a reliable biomarker of myocardial injury in AHF in the ED and should be considered as a risk stratification parameter for these subjects regardless of the left ventricular function. Further larger prospective studies are needed to confirm these preliminary data.
Enstrophy and dissipation must have the same scaling exponent in the high Reynolds number limit of fluid turbulence

Writing the Poisson equation for the pressure in the vorticity-strain form, it is shown that the pressure has a finite inertial range spectrum in the high Reynolds number limit of isotropic turbulence only if the anomalous scaling exponents μ and μω for the dissipation and enstrophy (squared vorticity) are equal. Since a finite inertial range pressure spectrum requires only very weak assumptions about high Reynolds number turbulence, it is concluded that the inference from experiment and direct numerical simulation that these exponents are different must be a finite-range scaling result which will not survive taking the high Reynolds number limit.
Effect of Implementing Nursing Interventions Bundle on Sleep Quality and Associated Delirium among Patients at Intensive Care Unit

Critically ill patients frequently experience sleep deprivation, which has detrimental effects such as increased pain perception, impaired cognitive function, and delirium. Aim: Evaluate the effect of implementing nursing interventions bundle on sleep quality and associated delirium among patients at intensive care unit (ICU). Design: A quasi-experimental research design was utilized in this study. Setting: General Intensive Care Unit of Beni-Suief University Hospital and Anesthesia Intensive Care Unit of Emergency hospital affiliated to Tanta University hospital. Subjects: A convenience sampling of 60 adult critically ill patients who admitted to the selected setting and divided into two equal groups; 30 patients in each (control and study groups). Tools; Tool (I) Patient interview schedule, tool (II) Richard Campbell Sleeping Questionnaire (RCSQ) and tool (III) Intensive Care Delirium Screening Checklist (ICDSC) Results: A highly significant difference among study and control groups regarding their total sleep quality after applying the nursing intervention bundle in which P=0.000. The incidence of delirium was reported among control group with a percentage of (30%) compared with only (13.33%) in study group after the seventh day of intervention with significant differences in which P=0.024. Conclusion: Marked improvement in sleep quality with decreasing severity of pain and incidence of associated delirium after applying nursing intervention bundle among study group compared with control group throughout period of the study. Recommendation: Sleep interventions bundle should be integrated into routine care for patients in ICU to promote patient sleep and reduce incidence of delirium.
Experimental evidence of cavitational effects in a Rayleigh step slider

The objective of this article is the study of the load-carrying capacity of a Rayleigh step slider (RSS) for both direct motion (+RSS – which generates lifting effects) and reverse motion (−RSS – which generates suction or cavitational effects). Normal force was measured on a pin-on-disc test rig, with two lubricants (SAE-20 W-50 oil and glycerin) at four speeds and three values of film thickness. During reverse motion (−RSS), cavitational effects have been observed for some test cases. It is supposed that surface tension influences the appearance of cavitational effects, and a modified capillary number, Ca+, is proposed as indicator of cavitation inception. Close-up views taken near the trailing edge of the pin show the occurrence of several streamers, typical for cavitational effects, only when Ca+ > 2. Numerical simulation as well as approximate analytical models are presented for both directions of motion. The comparison of predicted theoretical results with the experimental data is satisfactory.
A new sample of extremely/ultra metal-poor stars

A sample of 30 very metal-poor stars from the Hamburg-European Southern Observatory (ESO) objective-prism survey have been observed at high spectral resolution at the Very Large Telescope (VLT) using the Ultraviolet and Visual Echelle Spectrograph (UVES). Two of the observed stars are very interesting not only because of their very low iron content, approximately four orders of magnitude lower than the solar value, but also because we detected the neutral lithium resonance line at 670.8 nm. Hydrogen lines suggest that the two observed stars have effective temperatures around 6000–6250 K and according to isochrones, they are either on the main–sequence or on the subgiant branch, in which case they would probably be the most metal-poor dwarfs or warm subgiants with lithium detections known. These detections would allow to determine more accurately the slope of the trend of the lithium abundance with [Fe/H] than was possible with samples of unevolved stars restricted to higher metallicities.
White Matter Correlates of Domain-Specific Working Memory

Prior evidence suggests domain-specific working memory (WM) buffers for maintaining phonological (i.e., speech sound) and semantic (i.e., meaning) information. The phonological WM buffer’s proposed location is in the left supramarginal gyrus (SMG), whereas semantic WM has been related to the left inferior frontal gyrus (IFG), the middle frontal gyrus (MFG), and the angular gyrus (AG). However, less is known about the white matter correlates of phonological and semantic WM. We tested 45 individuals with left hemisphere brain damage on single word processing, phonological WM, and semantic WM tasks and obtained T1 and diffusion weighted neuroimaging. Virtual dissections were performed for each participants’ arcuate fasciculus (AF), inferior fronto-occipital fasciculus (IFOF), inferior longitudinal fasciculus (ILF), middle longitudinal fasciculus (MLF), and uncinate fasciculus (UF), which connect the proposed domain-specific WM buffers with perceptual or processing regions. The results showed that the left ILF, MLF, IFOF, and the direct segment of the AF were related to semantic WM performance. Phonological WM was related to both the left ILF and the MLF. This work informs our understanding of the white matter correlates of WM, especially semantic WM, which has not previously been investigated. In addition, this work helps to adjudicate between theories of verbal WM, providing some evidence for separate pathways supporting phonological and semantic WM.
Training of The Utilization of Medicinal Plants as Complementary Medicine Among Health Workers

The current community service focused on the use medicinal plants which seemed to increase among families. This program was supported by the 2018 Riskesdas report, which showed that 38.7% of Indonesia’s population had used traditional medicine for treatments. This program sought to discover health workers’ knowledge of family medicinal plant training. This community service was carried out through the mentoring method and involved 25 public health center employees representing each primary healthcare in Ogan Ilir Regency. We selected the sample using the total sampling method. The mentoring session was organized in the form of training related to the concepts of family medicinal plants and how to use them. This training involved a number of lectures and presentations of a model of family medicinal plants. The diﬀerences in knowledge of the training participants were measured using a pretest and posttest. The data were analyzed using the t-test. The results showed a diﬀerence in health workers’ knowledge before and after the training (p <0.05). There is an increase in the knowledge of primary healthcare workers regarding family medicinal plants.

Drag with external and pressure drop with internal flows: a new and unifying look at losses in the flow field based on the second law of thermodynamics

Internal and external flows are characterized by friction factors and drag coefficients, respectively. Their definitions are based on pressure drop and drag force and thus are very different in character. From a thermodynamics point of view in both cases dissipation occurs which can uniformly be related to the entropy generation in the flow field. Therefore we suggest to account for losses in the flow field by friction factors and drag coefficients that are based on the overall entropy generation due to the dissipation in the internal and external flow fields. This second law analysis (SLA) has been applied to internal flows in many studies already. Examples of this flow category are given together with new cases of external flows, also treated by the general SLA-approach.
Hepatectomy After Conversion Therapy for Initially Unresectable HCC: What is the Difference?

Purpose Conversion therapy gives some patients with initially unresectable hepatocellular carcinoma (HCC) access to surgery. The purpose of this study was to evaluate the safety and efficacy of hepatectomy after conversion therapy and how it differed from those who undergoing direct hepatectomy. Patients and Methods From January 2018 to April 2022, 745 patients underwent hepatectomy for HCC were enrolled. Among them, 41 patients of unresectable HCC underwent hepatectomy after conversion therapy. A demographically and clinically comparable cohort was created from the remaining patients in a 1:1 ratio using propensity score matching. Results The median duration of conversion therapy was 108 (42–298) days, 8 patients achieved complete response (CR) and 33 achieved partial response (PR). Conversion therapy resulted in some degree of myelosuppression, but liver function index remained good. Compared with the direct hepatectomy group, the conversion group had more blood loss (600 mL vs 400 mL, p=0.015), longer operative time (270 min vs 240 min, p=0.02), higher blood transfusion rates, and longer hospital stay (8 days vs 11 days, p<0.001). Patients in the conversion group had significantly more complications of any grade (82.9% vs 51.2%, p=0.002) and grade 3/4 (26.8% vs 4.9%, p=0.013), and 6 patients developed post-hepatectomy liver failure (PHLF). There were no deaths in either group. All patients achieved R0 resection, 6 (6/41, 14.6%) achieved pathological complete response (pCR), 14 achieved major pathologic responses (MPR). During a median follow-up of 12.8 months, 14 patients in the conversion group experienced recurrence or metastasis, no deaths. Conclusion Hepatectomy after conversion therapy was more difficult than direct hepatectomy, but accurate preoperative assessment could ensure the safety of the surgery. The damage of liver function after conversion therapy was more severe than expected, PHLF should be prevented and treated. Hepatectomy was effective and necessary, postoperative pathological examination could provide guidance for adjuvant therapy.
The COVID‐19 pandemic and trade in agricultural products

Abstract In this study, we develop a structural gravity model to analyse the effects of the ongoing COVID‐19 pandemic on international trade in food and agriculture. Using detailed data on trade flows, we estimate the trade impacts of the pandemic for major sectors in food and agriculture. Supply‐side impacts on trade caused by reductions in labour tend to be largest in labour‐intensive sectors such as meat processing and processed fruit and vegetables. The supply‐side export effects are dwarfed by the demand‐side import effects, as the recessionary impact of the pandemic drives significant decreases in imports, largely in processed goods and labour‐intensive commodities.
Nonparametric estimation of a periodic function

SUMMARY Motivated by applications to brightness data on periodic variable stars, we study nonparametric methods for estimating both the period and the amplitude function from noisy observations of a periodic function made at irregularly spaced times. It is shown that nonparametric estimators of period converge at parametric rates and attain a semiparametric lower bound which is the same if the shape of the periodic function is unknown as if it were known. Also, first-order properties of nonparametric estimators of the amplitude function are identical to those that would obtain if the period were known. Numerical simulations and applications to real data show the method to work well in practice.
Dynamic behaviour of beams and rectangular plates under moving loads

Abstract A theory concerning the dynamic response of finite elastic structures (Rayleigh beams and plates) having arbitrary end supports and under an arbitrary number of moving masses is developed. The versatile solution technique presented is based on modified generalized finite integral transforms and the modified Struble’s method. Various analytical results are presented. Numerical examples are given and the results compare favourably with existing ones. The efficiency of the solution technique is demonstrated and discussed.
Refugee Migration to Europe – Current Challenges and Potentials for Cities and Regions

“Europe’s migrant crisis: The year that changed a continent” (Evans 2020) is a contribution published in BBC news in August 2020. Whether one should speak of a crisis is a question of perspective. However, it is undisputed that European society has changed in many fi elds by the refugee movements that took place in 2015 and 2016. Since migration processes always materialise in concrete places, the spatiallocal level, in which migrants are mobile and also immobile during a migration and at the (temporary) end of a migration movement, is omnipresent in research processes. Migration without space does not exist, neither in the imaginaries of migration nor in the practice of migration. All levels of space are addressed, from the EU level to the municipal level, for example, when it comes to political-administrative spaces, or neighbourhoods and individual fl ats of a household, when it is more the sociospatial dimension that is addressed. In this respect, all spaces are also present in this Special Issue, with a particular focus on the regional and municipal levels with their concrete places of organisation and materialisation of fl ight. For refugee studies, the municipal level is also of great importance, because fi rst, the basic necessities of life, from food to shelter, must be provided by local institutions. And second, integration processes, even under the restrictive conditions for refugees, e.g. due to the usual work ban in the initial phase, primarily take place at this level. In contrast to other forms of migration, this dependency of refugees on local authorities is signifi cantly greater, as is the challenge for local offi ces to organise the fi nancial and human resources to meet the obligation to secure basic needs. The fact that studies at the small-scale level are always linked to all other levels and thus determine the everyday lives of refugees as well as challenge research concepts is particularly evident in the study by Bolzoni et al. (2022) in this Special Issue. Comparative Population Studies Vol. 47 (2022): 513-532 (Date of release: 21.12.2022)
Modelling atrazine sorption in carbon-rich substrates: a case study

: Background: The use of carbonaceous materials for environmental remediation is attractive due to low expense and high sorption capacity. However, their efficiency in contaminant removal is affected by substrate composition and sorption mechanism. Objective: This study investigated atrazine sorption and desorption in three carbon-rich substrates. Data were evaluated considering isotherm models and sorbent chemical composition. Methods: Sorption was performed by the batch equilibrium method with three substrates obtained from pig slurry composting with different proportions (w/w) of charcoal fines (CF): CF0, CF9 (9% CF), and CF18 (18% CF). The substrates were characterized by elemental analysis, 13 C NMR CP/MAS spectroscopy. The Freundlich and Dubinin-Radushkevich (DRK) models better fitted the sorption data (0.96>R 2 >0.81), followed by Temkin (0.95>R 2 >0.76). Charcoal addition to composting substrates increased carbon content and the aromaticity in the order CF0<CF9< CF18. However, the sorption affinity decreased in the opposite order as indicated by the Kf values: 675, 335 and 290 L kg -1 , respectively. Values of the E parameter (DRK) varied from 8.05 to 8.29 kJ mol -1 , suggesting a predominant physical sorption mechanism, whereas the Bt coefficient (Temkin) indicated an endothermic process. Desorption was only observed at higher atrazine concentrations (>10 mg L -1 ), and the desorption Kf values were greater than the respective sorption values. Conclusions: Atrazine sorption in the tested C-rich substrates is not governed by the carbon content or aromaticity. The low sorption reversibility implies a low atrazine mobility from the tested substrates and suggests their potential for herbicide removal in the environment.
