“I'm No Criminal, I'm Just Homeless”: The Greensboro Homeless Union's efforts to address the criminalization of homelessness
Authors: Craven Krista , Sapra Sonalini , Harmon Justin , Hyde Marcus 
Published: July 2021

AbstractThis paper examines how homelessness is criminalized in Greensboro, North Carolina, and the ways in which the Homeless Union of Greensboro (HUG) has contested such criminalization. This paper draws on data from a participatory action research study conducted between 2018 and 2020 by a group of researchers from two local universities and members of HUG. Findings from our study suggest that law enforcement officers in Greensboro use a vast array of laws to harass, ticket, and arrest people experiencing homelessness, particularly those who are Black. Findings also suggest that when individuals experiencing homelessness seek help for citations or arrests, it is challenging to access quality, affordable legal representation. This paper illustrates how HUG takes a multi‐pronged approach to address the variety of policies and practices that target homeless people, particularly people of color, recognizing that systems change requires a multifaceted approach that adapts to dynamic social and political contexts.
The critical role of B4GALT4 in promoting microtubule spindle assembly in HCC through the regulation of PLK1 and RHAMM expression
Authors: Dai Zhe , Wang Kun , Gao Yin 
Published: July 2021

AbstractBeta 1,4‐galactosyltransferase (B4GALT)‐family glycosyltransferases are involved in multiple biological processes promoting cancer progression, regulating the dynamic network of cancer cell proliferation and apoptosis, and are associated with metastasis. However, their roles in the dysregulation of expressions and functions in hepatocellular carcinoma (HCC) remain unclear. Herein, bioinformatic approaches have been applied to investigate their expression profiles, and to obtain correlations between gene expressions and clinicopathological parameters as well as downstream target genes in HCC. Multiple databases were used to screen the expressions of B4GALT family members in tumor tissues, and to evaluate their prognostic value among HCC patients in different aspects. Results indicated an overall upregulation of B4GALTs' transcription levels in tumor tissues and a strong correlation with poor prognosis. Through Gene Ontology analysis, gene set enrichment analysis, and verification of single‐cell RNA sequencing data, we established a connection between the B4GALT family and microtubule spindle assembly, which particularly highlighted the role of B4GALT4 in this phenomenon. B4GALT4 knockdown downregulated the production of lumican, and repressed the expressions of polo‐like kinase 1 and RHAMM by regulating the transforming growth factor‐beta pathway, thus suggesting that B4GALT4 is a critical promotor for HCC. We believe that these studies will provide valuable insight into the role of B4GALT family members in HCC and lead to the development of new strategies to improve the outcomes for patients with HCC.
Impact of a large artificial lake on regional climate: A typical meteorological year Meso‐NH simulation results
Authors: Iakunin Maksim , Abreu Edgar F.M. , Canhoto Paulo , Pereira Sara , Salgado Rui 
Published: July 2021

AbstractLarge artificial lakes and reservoirs affect the meteorological regime of the shore area and the local climate takes on a number of new features that were previously absent. This work focuses on the weather impact of the Alqueva reservoir, the largest artificial lake in Western Europe. An extensive set of numerical simulations using Meso‐NH mesoscale atmospheric model coupled with FLake (Freshwater Lake) scheme was carried out. The simulations covered a 12‐month period that was chosen to compose a so‐called Typical Meteorological Year. This artificial time period is meant to represent the typical meteorological conditions in the region and the model results are used to assess the changes in the local climate. To evaluate the raw impact of the reservoir, two different scenarios of simulations were compared: (A) with the reservoir as it exists nowadays and (B) without the reservoir using the older surface dataset. The results show decrease of air temperature during daytime (10–9°C) and nighttime increase (up to 10°C). In nearest towns, daily maximum temperature decreased and daily minimum temperature increased, which refers to milder weather conditions. Alqueva mainly showed suppression in fog formation in the nearby area. Local breeze regime was studied and monthly lake/land breezes were described.
Plio‐Pleistocene mammals from Mille‐Logya, Ethiopia, and the post‐Hadar faunal change

Published: July 2021

ABSTRACTWe describe the non‐primate mammalian fauna from the late Pliocene to earliest Pleistocene deposits of Mille‐Logya in the Lower Awash Valley, Ethiopia, dated to c. 2.9–2.4 Ma, and divided into three successive units: Gafura, Seraitu, and Uraitele. We identify 41 mammalian taxa (including rodents), the most diverse group being the Bovidae, with 17 taxa. While the Gafura assemblage still resembles those from the earlier Hadar Formation, the younger Seraitu assemblage documents a major turnover. While there is little change in the species present across this interval, the relative abundances of various taxa change dramatically, with suids being largely replaced by open‐country bovids (Alcelaphini and Antilopini). We interpret this faunal change as reflective of an environmental shift, contemporaneous with the replacement of Australopithecus afarensis by Homo in the area.

Published: July 2021

ABSTRACTThe investigation of a limestone cave on the Ryonggok‐ri of Sangwon County, North Hwanghae Province, DPRK, has yielded many faunal remains including Late Pleistocene deer, brown bears and horses. Uranium series dating of fossil teeth yielded dates of ~72ka at the base of Layer 2 – the bone‐bearing unit – and ~44ka at the top. The rich and diverse mammal remains of Ryonggok Cave No. 1 are indicative of warm and humid temperate conditions during the Late Pleistocene, and reflect the presence of both dense forests and open grassland. In addition, pollen and spores from the site include two families and 24 genera of trees, six families and a genus of grasses and herbs, and two families and six genera of ferns, corroborating the environments inferred from the faunal remains.

IntroductionManagement of retroperitoneal and lateral pelvic lymph nodes (RLPN) in rectal cancer remains unclear. With total neoadjuvant therapy (TNT), more patients have radiologic complete clinical response (rCR). We sought to evaluate the impact of radiographic persistent RLPN after neoadjuvant therapy on survival.Materials and MethodsPatients with rectal adenocarcinoma with isolated RLPN metastasis, who received neoadjuvant therapy before surgery were included from the United States Rectal Cancer Consortium database. Primary outcomes were recurrence‐free survival (RFS) and overall survival (OS).ResultsOf 77 patients, all received neoadjuvant therapy, with 35 (46%) receiving TNT. Posttreatment, 33 (43%) had rCR while 44 (57%) had radiographic persistent RLPN. Median number of radiographic positive RLPN was 1 (IQR 1–2).Receipt of TNT was associated with radiographic RLPN rCR (OR 4.77, 95% CI 1.81–12.60, p < .01). However, there was no difference in RFS and OS between patients who achieved rCR or with persistent RLPN (all p > .05).ConclusionsRadiographic persistence of RLPN was not associated with worse survival in well‐selected patients and may not be a reliable indicator of pathological response. TNT may be the preferred management strategy to select patients given its association with rCR. Radiographic persistence of RLPN after preoperative therapy should not necessarily preclude surgery.

AbstractObjectiveTo explore the safety, feasibility and clinical effect of transvaginal natural orifice specimen extraction surgery (NOSES) in 3D laparoscopic nephroureterectomy (LNU) for upper tract urothelial carcinoma (UTUC).MethodsA retrospective analysis was made of 16 female patients who underwent 3D LNU and NOSES in the Department of Urology, Cancer Hospital, Chinese Academy of Medical Sciences from June 2019 to December 2020. The basic clinical data, perioperative related data, perioperative complications, visual analogue pain score (VAS), postoperative scar assessment questionnaire (PSAQ) at 3 months, female pelvic floor dysfunction questionnaire (PFDI‐20) and female sexual function index questionnaire (FSFI) at preoperative and postoperative 3 months were analyzed and evaluated.ResultsThe surgery was successfully completed in all 16 patients, and none of them was converted to open surgery. No postoperative complications, such as abdominal incision‐related infection. No cases of local recurrence and distant metastasis were observed during follow‐up of 3 to 21 months. The VAS scores at 24 h and 48 h after operation were 2.9 ± 0.7, 1.3 ± 0.6, respectively. PSAQ scores at 3 months after operation were 34.3 ± 3.3. PFDI‐20 scores of women preoperative and postoperative 3 months were 6.25 ± 1.75, 6.3 ± 1.8, respectively, and the difference was not statistically significant (p = 0.924). There was no significant difference in FSFI scores between preoperative and postoperative 3 months (p = 0.892).ConclusionTransvaginal NOSES in 3D LNU for UTUC is safe, feasible and practical. The successful development of this technique has laid a solid foundation for further clinical application and promotion.

Authors: Han Seung Hoon , Chung Eun‐Jae 
Published: July 2021

AbstractObjectiveThis study aimed to analyze the usefulness of an additional axillary port in robotic retroauricular thyroidectomy by comparing the perioperative data and postoperative function between the operations with and without an additional axillary port.Materials and methodsA retrospective review of the medical records of 11 patients who underwent robotic thyroid operations using a unilateral retroauricular approach with or without an additional axillary port between 2016 and 2021 was conducted. Patient demographics, operation time, drainage amount, hospital stay, complication, postoperative cosmetic satisfaction, and postoperative neck and shoulder pain were analyzed.ResultsAmong the 11 patients who underwent robotic retroauricular thyroidectomy, an additional axillary port was used in 6 patients and not used in 5 patients. The total operation time was significantly shorter in the axillary port group (174.5 ± 23 minutes) compared to the without the axillary port group (207.6 ± 20.1 minutes) (P = .033). The intraoperative estimated blood loss (P = .525), total amount of drainage (P = .172), and postoperative hospital stays (P = .092) were not different between the 2 groups. There was no postoperative recurrent laryngeal nerve palsy, hypoparathyroidism, hematoma, seroma in the two groups. There was no significant difference for either group in the pain score and cosmetic satisfaction at 2 weeks (P = .378, P = .650) and 6 weeks (P = .242, P = .546) postoperatively.ConclusionRobotic retroauricular thyroidectomy using an additional axillary port was a novel, safe, and feasible procedure. Dissection was easy due to the availability of the fourth robotic arm to retract the thyroid gland.Level of Evidence: 4.
Polymerization Enhancers for Cyanoacrylate Skin Adhesive
Authors: Kumar Awanish , Domb Abraham J. 
Published: July 2021

AbstractCyanoacrylate glues are a renowned synthetic tissue sealant that cures rapidly through polymerization at room temperature, felicitating medical glues to treat skin wounds and surgical openings. Despite a wide range of cyanoacrylates available, only 2‐octyl cyanoacrylates (OCA) provides the best biocompatibility. In this study, the polymerization and adhesive properties of 2‐octyl cyanoacrylates (OCA) are explored in the presence of a highly biocompatible and biochemically inert polymer, poly(ethylene glycol) polyhedral oligomeric silsesquioxane (PEG‐POSS). The effect of PEG‐POSS on the polymerization of OCA is examined on a plastic surface and over pig skin. A peel‐test is performed to evaluate the strength of OCA adhesive properties between two pieces of pig skin samples. Additionally, thin films of OCA are prepared using different fillers and evaluated for tear test. The results reveal that when applied on the plastic or pig skin, PEG‐POSS initiated polymerization in OCA yields a high molecular weight OCA polymer with much better adhesive properties compared to commercially available cyanoacrylate adhesives. The relative change in the molecular weights of OCA compared to commercially available cyanoacrylate bioadhesives such as Dermaflex is much higher. The pig skin peeling test shows that OCA needs higher peeling force than Dermaflex.
König's lemma, weak König's lemma, and the decidable fan theorem
Authors: Fujiwara Makoto 
Published: July 2021

AbstractWe provide a fine‐grained analysis on the relation between König's lemma, weak König's lemma, and the decidable fan theorem in the context of constructive reverse mathematics. In particular, we show that double negated variants of König's lemma and weak König's lemma are equivalent to double negated variants of the general decidable fan theorem and the binary decidable fan theorem, respectively, over a nearly intuitionistic system containing a weak countable choice only. This implies that the general decidable fan theorem is not equivalent to the binary decidable fan theorem in the absence of a strong countable choice. In addition, we introduce a principle which fills the gap between König's lemma and weak König's lemma, and show that König's lemma is equivalent to weak König's lemma plus this principle. We also solve several problems arising from the investigation.

Brand narratives: Content and consequences among heritage brands
Authors: Pfannes Christina , Meyer Caroline , Orth Ulrich R. , Rose Gregory M. 
Published: July 2021

AbstractThis study bridges the gap between the managerial view and the consumer view integrating research on storytelling with consumer perceptions of brand heritage. It identifies key elements of the stories told by managers of heritage product brands and consumer responses to these elements. Adopting a mixed‐methods approach, four empirical studies (in‐depth interviews with managers, content analysis of brand websites, a survey, and an experiment) provide evidence for relevant story elements, their use by heritage brand managers and their effects on consumers' responses. With several variables included as controls (consumer age, anxiety state, biological sex, brand familiarity, category involvement, category knowledge and verbal processing style), the findings indicate that brand managers' assumptions about the effectiveness of specific narrative elements do not entirely reflect consumer' responses to these elements. Managers (Studies 1 and 2) commonly employ the story elements of the date of foundation, people, technology, omni‐temporality, struggle, and the place of foundation. While consumers (Studies 3 and 4) infer heritage from the brand's date of foundation, omni‐temporality, and technology, the results are less unanimous for the story elements of people, struggle, and place of foundation.
Effect of the rotor cage chassis on inner flow field of a turbo air classifier
Authors: Yu Y. , Kong X. , Ren C. , Liu J. , Liu J. 
Published: July 2021

AbstractAs the connection between the center of rotor cage and the coarse powder collecting cone, rotor cage chassis of the turbo air classifier directly influences airflow movement in the classifier. In order to study the effect of rotor cage chassis on the inner flow field of a turbo air classifier, the flow fields of four rotor cage chassis structures with different opening size are simulated and compared using ANSYS‐FLUENT 17.0. The simulation results show that there is “bypass flow” phenomenon for the classifier with the open rotor cage chassis, compared with the closed rotor cage chassis. The “bypass flow” phenomenon can change the airflow velocity distribution of the annular region. For the open rotor cage chassis, its opening size has no significant effect on the flow field distribution and the airflow velocity. However, the open or closed rotor cage chassis has great effect on the flow field distribution and the airflow velocity. The calcium carbonate classification comparative experiments are carried using the open and closed rotor cage chassis structures. The experiment results show that the open rotor cage chassis can decrease the cut size, and the closed rotor cage chassis can improve the classification accuracy.

Published: July 2021

AbstractLaser beam melting (LBM) is an advanced manufacturing technology providing special features and the possibility to produce complex and individual parts directly from a CAD model. TiAl6V4 is the most common used titanium alloy particularly in biomedical applications. TiAl6Nb7 shows promising improvements especially regarding biocompatible properties due to the substitution of the hazardous vanadium. This work focuses on the examination of laser beam melted TiAl6Nb7. For microstructural investigation scanning electron microscopy including energy‐dispersive x‐ray spectroscopy as well as electron backscatter diffraction are utilized. The laser beam melted related acicular microstructure as well as the corresponding mechanical properties, which are determined by hardness measurements and tensile tests, are investigated. The laser beam melted alloy meets, except of breaking elongation A, the mechanical demands like ultimate tensile strength Rm, yield strength Rp0.2, Vickers hardness HV of international standard ISO 5832‐11. Next steps contain comparison between TiAl6Nb7 and TiAl6V4 in different conditions. Further investigations aim at improving mechanical properties of TiAl6Nb7 by heat treatments and assessment of their influence on the microstructure as well as examination regarding the corrosive behavior in human body‐like conditions.
Strain behaviour of aluminum 99.5 in micro‐forming conditions of the coining process
Authors: Mihaljević M. , Piljek P. , Keran Z. , Markučič D. 
Published: July 2021

AbstractThe coining process can be identified as a shallow die forging. By using this process, it is possible to produce very fine surface geometries. This leads to dimension scaling into micro dimensions and causes the specific material behavior. In the micro area, continuum laws are not strictly followed anymore. The leading role in determining the deformation and strain level is taken by the fine surface geometry dimension and the size of the crystalline grain of the workpiece material. This is known as the size effect and defines all micro‐forming processes. In order to provide monitoring of the filling of the smallest die dimensions, additional supporting procedures should be used. In this case, radiography testing procedures for observing the specific points of the workpiece geometry are applied, characterized with very small dimensions (less than 0.5 mm). Testing aluminum samples are formed using two techniques – open and closed die coining, with identical surface geometry. Their crystalline structures are in two‐grain sizes of 34 μm and 80 μm. Scanning results show different material behaviour and different surface deformation for the same level of forming force in all four testing cases.
Optimisation of spatially‐encoded diffusion‐ordered NMR spectroscopy for the analysis of mixtures

Published: July 2021

AbstractDiffusion‐ordered NMR spectroscopy (DOSY NMR) is a widely used method for the analysis of mixtures. It can be used to separate the spectra of a mixture's components and to analyse interactions. The classic implementation of DOSY experiments, based on an incrementation of the diffusion‐encoding gradient area, requires several minutes or more to collect a 2D data set. Spatially‐encoded (SPEN) DOSY makes it possible to collect a complete data set in less than 1 s, by spatial parallelisation of the effective gradient area. While several short descriptions of SPEN DOSY experiments have been reported, a thorough characterisation of its features and its practical use is missing, and this hinders the use of the method. Here, we present the unusual principles and implementation of the SPEN DOSY experiment, an understanding of which is useful to make optimal use of the method. The encoding and acquisition steps are described, and the parameter relations that govern the setup of SPEN DOSY experiments are discussed. The influence of key parameters, including on sensitivity, is illustrated experimentally on mixtures of small molecules. This study should be useful for the setup of SPEN DOSY experiments, which are particularly useful for systems that evolve in time.
