The invisible hand of an invisible population: Dynamics and heterogeneity of second‐home housing markets
Authors: Back Andreas , Marjavaara Roger , Müller Dieter K. 
Published: March 2022

AbstractThe effects of second‐home tourism on property markets has been one of the key debates in second‐home research. This has been discussed in association with property speculation, financial vulnerability, gentrification, displacement, and rural development. This paper studies the market prices for all detached homes traded on the open market in Sweden during 1999–2017. It investigates how the market values of second homes have developed over time and how they vary spatially. Results show clear and growing spatial inequalities over the period. It emphasises the dynamic interplay between different forms of dwelling use and the close relationship to spatial context.

AbstractIncreasingly, lesbian, gay, and bisexual (LGB) individuals are fleeing the 67 countries that criminalize consensual same‐sex intimate relationships, seeking asylum in countries such as the United States. Minority stress theory posits that compared with non‐LGB refugees and asylum seekers (RAS), LGB RAS are likely to face persecution, rejection, and discrimination and have a higher risk of experiencing posttraumatic stress disorder (PTSD) symptoms. This study assessed differences in sociodemographic characteristics, persecution experiences, and mental health outcomes among 959 RAS persecuted for same‐sex behavior (pLGB RAS) who presented for care and social services at the Boston Center for Refugee Health and Human Rights. Data were derived from intake interviews with RAS clients that elicited torture experiences and assessed PTSD symptoms using the Short Screening Scale for PTSD. Over 11% of the total sample were pLGB RAS. Compared with non–pLGB RAS, pLGB RAS reported higher PTSD symptom levels, β = .08, p = .031; more difficulty loving others, d = 0.13, p < .001; and feeling more isolated, d = 0.10, p = .005. pLGB RAS reported more persecution, d = 0.31, p = .002; physical assaults, d = 0.22, p = .029; and psychological assaults, d = 0.20, p = .047; and were more likely to be asylum seekers, d = 0.11, p = .001, and have experienced persecution in Uganda, d = 0.39, p < .001, and other countries that criminalize same‐sex acts, d = 0.26, p < .001. More research is needed to understand clinical outcomes and implications of treatment for this population.

AbstractBackgroundMerkel cell carcinoma (MCC) is a rare and aggressive cutaneous neuroendocrine malignancy. Immune checkpoint inhibitors (ICIs) have transformed the treatment landscape for patients with metastatic MCC (mMCC). In mMCC, the response duration after cessation of ICIs treatment for complete response (CR) is unknown.ObservationWe report a case of a woman in her 70s with metastatic MCC treated in first‐line with avelumab. The treatment was stopped after 2 years of CR. The patient relapsed after 11 months of cessation of treatment and rechallenge with avelumab at the same dosing regimen was decided. The first tumour assessment at 3 months after reintroduction revealed a CR.DiscussionIn contrast with observations made for patients who have discontinued ICIs in the metastatic melanoma setting, disease progression is observed after ICIs cessation in mMCC including for patients with low tumour burden and who achieve a CR.ConclusionThe case of our patient underlines this risk of relapse and suggests great caution before stopping ICIs in patients treated for mMCC, even when they are in CR.
Molecular Inclusion of Small Aging Products into the Hexanitrohexaazaisowurtzitane (CL‐20) Lattice: Part I, Infrared Spectra
Authors: Beste Ariana , Alam Mary Kathleen 
Published: March 2022

AbstractAccelerated aging studies of β CL‐20 thin films deposited on glass surfaces in different environments (N2, air, air/water) were conducted. Samples were analyzed with attenuated total reflectance infrared (ATR‐IR) spectroscopy. Spectral features of molecular lattice inclusions in CL‐20 films aged in an air/water environment were observed. The features occurred after β CL‐20 polymorph transformation to α CL‐20 and were accompanied by the appearance of lattice water peaks. To assist ATR‐IR peak assignment, density functional theory studies were performed, and IR spectra of α CL‐20 lattice inclusions of small molecules that were identified as degradation products of CL‐20 were computed. Simulated spectra of NO2, HNCO, N2O, and CO2 incorporated into partially hydrated α CL‐20 matched the experimental spectrum of β CL‐20 thin films aged in air/water.

AbstractIntroductionPartial pulmonary venous return anomalies (PPVRA) were not considered as a good candidate for robotic surgery in early time of robotic cardiac surgery. In this study, we present our experience in patients undergoing robotic atrial septal defect (ASD) and PPVRA surgery.MethodsBetween November 2014 and January 2020, data of 21 patients underwent robotic ASD with PPVRA was collected. Inclusion criterion was presence of right‐sided PPVRA with ASD. All operations were performed robotically.ResultsThe mean age of patients was 26.7 ± 10.3 years. Seventeen patients (81%) had superior‐caval ASD with supracardiac PPVRA and double‐patch technique was used. Four patients had inferior‐caval ASD with intracardiac PPVRA and single‐patch technique was preferred. Cross‐clamp time and cardiopulmonary bypass time were 92.8 ± 29.6 and 127.8 ± 38.1, respectively. There was no mortality. One patient had atrioventricular‐block and required pacemaker.ConclusionRobotic repair of ASD with PPVRA is feasible and effective method as an alternative to conventional surgery.
Surface modifications of PET in argon atmospheric pressure plasma: Gas flow rate effect
Authors: Abdel‐Fattah Essam 
Published: March 2022

The correlation between plasma optical properties and the treated polyethylene terephthalate (PET) surface characteristics have been studied at various Ar flow rate. The rotational Trot and vibrational Tvib temperatures of APPJ were determined from SPS emission band. The pristine and plasma‐treated PET surfaces were characterized by several techniques including X‐ray photoelectrons spectroscopy (XPS), Raman spectroscopy, contact angle (CA), and atomic force microscope (AFM). The CA decreased rapidly in the flow rate range 1–3 L/min and weakly dependent as flow rate > 3 L/min. XPS results showed that C 1s % of plasma‐treated PET surfaces decreases and has a minimum for samples treated at 3–4 L/min, while O 1s has a maximum at the same flow rate range. The carbon C 1s peak of pristine and plasma treated PET samples resolved into five subcomponents: C–C, C–O, C=O, O–C=O, and π–π bonds with variable percentage ratio accordance to the plasma gas flow rate. Raman data revealed a partial loss in the crystallinity of the treated PET samples and also confirm the incremental of C–O band at Ar flow rate of 3 L/min. AFM images showed that the surface roughness of treated PET films increases as Ar flow rate increases.

Published: March 2022

AbstractThe rechargeable magnesium battery (RMB) is regarded as a high‐energy, safe, and cost‐effective alternative for conventional batteries. Unfortunately, the passivation and uneven Mg growth not only raise the voltage hysteresis but also shorten the cycle life of RMBs. In this review, Mg passivation induced by electrolytes/contaminants, growth patterns of high dimensional Mg0, and mechanisms of Mg anode degradation are discussed. The recent efforts on suppressing electrolyte decomposition and uneven Mg growth including electrolyte/interphase modifications through additives, weakly coordinating anions, artificial interphases, and 3D magnesiophilic hosts are summarized. Finally, the future directions in stabilizing Mg anode and realizing high‐performance RMBs are highlighted.

Published: March 2022

AbstractThe advancement in the internet of things (IoT) is bringing changes in our daily lives. The widespread adoption of the IoT in a variety of areas sets the basis for smart living while also posing privacy and security concerns. Authentication and key agreement (AKA) protocol provides identity authentication for participants in a communication system and generates a temporary session key for participants to securely transmit messages. In addition to this, the adoption of smart cards adds a second line of defense in AKA protocols for IoT. To enhance the security of AKA protocols for IoT, many AKA protocols are proposed, but the majority of them fail to manage the balance between security and efficiency. To achieve both security and efficiency together for IoT, based on the elliptic curve public‐key cryptography, we design a three‐factor AKA protocol. We follow security analysis and efficiency analysis to analyze the security and efficiency. By comparing with related existing protocols, it is found that this protocol achieves security and efficiency attributes. The investigation shows that the protocol can meet key security requirements, consumes less computing resources, and is especially suitable for IoT scenarios with high security and efficiency.

AbstractThe mechanical behaviors of 12 high predamaged reinforced concrete (RC) rectangular columns strengthened with carbon fiber reinforced polymer (CFRP) under eccentric compression were experimentally investigated. The effects of the predamaged degree (), CFRP strips spacing () and eccentricity () on failure mode, bearing capacity, strain behaviors of CFRP strengthened predamaged columns were examined systematically. Test results demonstrated that the strengthened RC columns with small‐eccentricity were destroyed by the yielding of compressive longitudinal steel bars and the crushing of compression concrete while the transverse CFRP strips were not ruptured. The failure mode of the strengthened RC columns with large‐eccentricity was distinguished by the yielding of tensile and compressive longitudinal steel bars, the rupturing of longitudinal CFRP sheet, and the crushing of compressive concrete. With the increase of predamaged degree or eccentricity, the maximum bearing capacity of specimens decreased. In contrast, CFRP strips spacing had little effect on bearing capacity. Considering the effect of predamaged degree and eccentricity, a modified model for conveniently predicting the stress–strain relationship of CFRP strengthened predamaged RC columns under eccentric compression was proposed. On the basis of experimental study, the influence coefficients of predamaged degree and eccentricity and a strain distribution coefficient of CFRP strips were introduced, a calculation formula for predicting bearing capacity of high predamaged rectangular RC columns strengthened with CFRP under eccentric compression was proposed and validated test data with good agreement.
Experimental investigation of response of HSTC beam encased with Hf‐ECC and LWAC
Authors: Soniya Soundararaj Manju , Chithra Rethnasamy 
Published: March 2022

AbstractThe present investigation deals with the flexural behavior of a new type of Hybrid steel, polypropylene Engineered Cementitious Composite (Hf‐ECC) ‐ Lightweight Aggregate Concrete (LWAC) encased Hybrid Steel Truss Composite (HSTC) beams and detailed parametric study of HSTC beams using Abaqus. Eight simply supported beams fabricated with identical hybrid steel truss, but with varying depths and layer arrangement of Hf‐ECC and LWAC were experimentally tested to investigate the effects of Hf‐ECC depth of HSTC beam on the ultimate load‐carrying capacities and failure modes. Test results show that cracking, yield, ultimate moments, and the ductility of HSTC beams are improved by increasing the depth of Hf‐ECC due to the excellent tensile properties of Hf‐ECC. In addition to the above enhancement, it is also found that the combined use of Hf‐ ECC and LWAC could improve the beams' general ductility and considerable energy dissipation capacity due to Hf‐ECC's excellent deformation ability besides reducing beams' weight. In addition to experimental work, a finite element model is used to predict the load‐deflection behavior of Hf‐ECC and LWAC‐encased HSTC beams.
Modeling coarse aggregate distribution in interfacial zone of new–old concrete in precast concrete structures
Authors: Zhao Jie , Li Fumin , Chen Zhixiang 
Published: March 2022

AbstractThere are a large number of interfacial zones of new–old concrete in precast concrete structures, and the wall effect causes the reduction of coarse aggregate in the interfacial zones, which leads to the weaker physical, mechanical and durability properties of this part. In the present paper, some new–old concrete specimens with different chiseled depths at the interfaces were made to simulate the wet joints of precast concrete structures. The distribution characteristics of the coarse aggregate volume fraction in the interfacial zones of new–old concrete specimens were obtained by DIP (Digital Image Processing) technology. The results show that the distribution of the coarse aggregate volume fraction in the interfacial zones is similar to a positive V‐shape (no chiseling) or partial V‐shape (chiseled interface), and is generally lower than that of the noumenons of new and old concrete (constant values). With the increase of chiseled depth, the valley point (i.e., the minimum value) of the distribution curve of coarse aggregate volume fraction in the interfacial zone will move upwards and offset toward the old concrete. When the offset reaches 2 mm from the interface, it remains stable. The multiple irregular cone‐shape small pits on the actual chiseled surface are abstracted into a single bulging slope pit, and the area ratio of new–old concrete on the cross section within the chiseled range is derived. On this basis, the model of the coarse aggregate volume fraction in the interfacial zone varied with the distance from the interface is proposed.

AbstractBackgroundChronic constipation (CC) is a major public health condition and CC management remains challenging.ObjectiveWe aimed to evaluate the CC (and subtypes) prevalence in a Southern Europe Mediterranean country using Rome IV criteria, and to assess related factors, toilet and healthcare seeking behaviours.MethodsCross‐sectional epidemiological survey, conducted in general community and representing the Portuguese population according to sex and age. The questionnaire covered bowel habits, factors potentially associated with CC (demographic, health/lifestyle, toilet behaviours) and data regarding healthcare seeking.ResultsFrom the study data of 1950 individuals were analyzed. The answer rate was 68% and 1335 questionnaires were available for calculation. The CC prevalence was 17.8%, with respectively 9.3% of Functional Constipation (FC) and 8.5% of Irritable Bowel Syndrome – subtype constipation (IBS‐C). The likelihood of constipation was significantly higher in younger (OR 1.01; 95% confidence interval [CI], 1.007–1.031), solo (OR 2.48; 95% CI, 1.7–3.47) and low‐income (OR 2.40; 95% CI, 1.77–3.47) individuals. Constipated individuals spent more time at defecation, longer than 5 min (p = 0.001), and had particular toilet behaviours (absence of a morning pattern [p = 0.008], the use of triggers [p = 0.001] and reading/technological material [p = 0.006]) to facilitate the evacuation. Only 39% of affected individuals sought medical advice, mainly IBS‐C patients (p = 0.018).ConclusionChronic constipation seems to impact 1 in each 5 Portuguese. Constipated patients are younger, solo, less active and with low income. They develop a clear toilet behaviour profile. FC and IBS‐C patients assume particular behaviours.

ABSTRACTObjectiveTo examine the association of umbilical venous diameter and flow in monochorionic diamniotic twin pregnancy with placental sharing and fetal demise.MethodsThis was a prospective longitudinal cohort study of a consecutive series of monochorionic diamniotic twin pregnancies that underwent ultrasound assessments at 12, 16, 20 and 28 weeks' gestation. Fetal biometry (crown–rump length at 12 weeks or estimated fetal weight (EFW) thereafter) and cord insertion sites were recorded at each visit, as well as the diameter of the umbilical vein (UV) in both the intra‐abdominal part and a free loop of the umbilical cord. Time‐averaged maximum velocity in the intra‐abdominal part of the UV was measured to calculate UV‐flow. Univariate and multivariate linear regression analyses were performed to assess the relationship between intertwin ratios of these variables and placental sharing at 12, 16, 20 and 28 weeks' gestation. Placental sharing was calculated by dividing the larger by the smaller placental share, as measured on placental injection studies after birth. Additionally, the Mann–Whitney U‐test and receiver‐operating‐characteristics‐curve analysis were used to explore the relationship between the occurrence of fetal demise and intertwin differences in fetal biometry, cord insertion sites, UV diameters and flow at 12, 16, 20 and 28 weeks.ResultsOf 200 consecutive monochorionic twin pregnancies enrolled, injection studies were performed in 165 (82.5%) placentas. On univariate analysis, intertwin differences in fetal biometry, cord insertions and UV variables were associated significantly with placental sharing at 12, 16, 20 and 28 weeks' gestation. On multivariate analysis, intertwin differences in fetal biometry, cord insertions and all three UV variables remained associated significantly with placental sharing at 12 and 16 weeks. However, at 20 and 28 weeks, only the intertwin EFW ratio was associated consistently with placental sharing. Fetal demise of one or both twins complicated 26 (13.0%) pregnancies. Differences in EFW and cord insertion sites were not associated significantly with fetal demise, while at 16 weeks, differences in intra‐abdominal UV diameter and flow were associated with an increased risk of subsequent fetal demise.ConclusionsAt 12 and 16 weeks' gestation, intertwin differences in UV diameter and flow reflect placental sharing more accurately than do differences in fetal growth and cord insertion sites. At 16 weeks, discordance in intra‐abdominal UV diameter and flow is also associated with an increased risk of fetal demise. © 2022 International Society of Ultrasound in Obstetrics and Gynecology.

Published: March 2022

AbstractBackgroundAs a population of non‐migratory Canada geese (Branta canadensis) has been growing in residential and recreational areas, public concerns on potential acquisition of zoonotic pathogens from Canada geese and their faecal deposits have been increasing.ObjectivesThe main study objective was to evaluate the prevalence of zoonotic microorganisms, Campylobacter spp., Cryptosporidium spp., Giardia spp. and Salmonella spp. and antimicrobial resistant Escherichia coli in faeces of Canada geese residing in North‐Central Oklahoma, United States.MethodsA total of 204 faecal samples were collected from 11 locations in North‐Central Oklahoma, where public recreational areas such as lakes and ponds were located, and Canada geese were commonly inhabited. Faecal samples were examined by a centrifugal flotation to evaluate the prevalence of Cryptosporidium spp. and Giardia spp. infections. A total of 180 faecal samples were grouped into 36 pooled samples and cultured using standard culture methods to detect the prevalence of Campylobacter spp. and Salmonella spp. infections. The antimicrobial resistance profile was determined on 32 E. coli isolates recovered from the 36 sample pools, using the Kirby Bauer Disk Diffusion method.ResultsThe targeted zoonotic pathogens were not identified by the faecal examinations performed. Of the 32 E. coli isolates, 17 isolates (53.1%) demonstrated resistance to ≥1 antimicrobial agent.ConclusionsTargeted zoonotic pathogens were not detected among the examined resident Canada geese in North‐Central Oklahoma. The findings of multiple‐antimicrobial resistant E. coli infections are potentially a public health concern although the prevalence was low in this study. Further, larger scale surveys are recommended.
