Abstract
Background: The majority of the current South Sudanese population in Australia arrived as refugees in the early 2000s, facing challenges related to dislocation, navigating a new culture while honouring their own own. Much of the research on the South Sudanese experience has been conducted in the early years after arrival, with resettlement stressors likely to influence narratives of identity as new immigrants.This study aimed to understand the lived experiences of identity among South Sudanese who are long-term residents of Australia after fleeing their birth country, migration, and re-building their lives.Methods: The qualitative study was underpinned by a phenomenological framework that characterised the experiences of study participants. Purposive and snowball sampling was used to recruit Sydney-residing adults who arrived in Australia through its humanitarian refugee program 10 or more years ago and were born in South Sudan. Semi-structured interviews explored how participants identified themselves in Australia, changes in their experiences over time, their social and general life situation in Australia, and perceptions (self and other) of South Sudanese people in Australia.Results: The 26 participants from refugee backgrounds all had similar experiences of dislocation, most arriving in Australia 10-19 years ago with family members. Most participants were in employment and had attained (sometimes multiple) educational qualifications.Participants described a multiplicity of interconnected domains that governed the negotiating and making sense of identity. Three key themes were identified: mutable identities - dependent on context; Identity in relation to children; and the influence of limited opportunities. These themes were mediated by other interwoven personal and structural factors that shaped experience and perception. Expressions of hope, pride and achievement were threaded through several of the interviews, particularly in relation to their children. There was also frustration related to employment challenges and discrimination that limited identity reconstruction.Conclusions: Our exploration of long-term lived experiences for South Sudanese migrants highlights the evolving and often conflicting factors that shape domains of integration and identity construction. The deeper, more nuanced understandings of bicultural identity within a strengths-based framework calls for better partnerships and services to support strengthened community and acculturalisation.

Abstract
Here, we report Fe2O3/N-doped carbon (Fe2O3/CN) composites via one-step facile calcination process by using FeOOH and PANI as precursor. The results show that N-doped carbon is helpful to enhance the electrochemical properties of Fe2O3. N-doped carbon not only enhances the conductivity of Fe2O3 electrode, but also alleviates the volume expansion of Fe2O3 in the process of repeated charge and discharge. In addition, the synergistic effect of Fe2O3 and N-doped porous carbon makes the composites show higher capacitive properties (538.7 mF/cm2 at 5 mA/cm2) and cycle life (100% retention after 2000 cycles). In addition, its superior electrochemical performance is also proved in symmetrical supercapacitor. After 4900 cycles with current density of 10 mA/cm2, its capacity retention rate is 100%. So Fe2O3/N-doped carbon as electrode materials for long-life symmetrical supercapacitors has broad application prospects.

Abstract
Palpation, as already mentioned in the ancient Egyptian medical text Ebers Papyrus, utilizes that solid tumors are stiffer than the surrounding tissue. However, cancer cell lines tend to soften, which may intuitively foster invasion by enhancing the ability of cancer cells to squeeze through dense tissue. This paradox raises questions besides the oxymoron itself: Does softness emerge from adaptation to the external microenvironment? Or are soft cells already present inside a rigid primary tumor mass to support cancer cell unjamming? We investigate primary tumor explants from patients with breast and cervix carcinomas on multiple length scales from the tissue level down to single cells. We find that primary tumors are highly heterogeneous in their mechanical properties. From the tissue level this heterogeneity persists down to the scale of individual cells in cancer cell clusters, resulting in a broad distribution of cell rigidities with a higher fraction of softer, more squeezable cells. Plus, squeezed cell shapes correlate with cancer cell motility. Mechanical modelling based on patient data reveals that a tumor mass as a whole is able to maintain a rigid, solid behavior even when it contains a significant fraction of very soft cells. Cell softening induced cancer cell unjamming generates heterogeneous cancer cell clusters with a solid backbone of rigid cells surrounded by soft motile cells.

Published: December 2021

Abstract
Utilizing self-consistent numerical simulation in good agreement with measurements, we analyze internal device physics, performance limitations, and optimization options for a unique laser design with multiple active regions separated by tunnel junctions, featuring surprisingly wide InGaN quantum wells. Contrary to common assumptions, these quantum wells are revealed to allow for perfect screening of the strong built-in polarization field, while optical gain is provided by higher quantum levels. However, internal absorption, low p-cladding conductivity, and self-heating are shown to strongly limit the laser performance.
Mobile Health Technologies could enhance Public Private Mix for Tuberculosis care in Rural Southwestern Uganda: Qualitative Findings
Authors: Tumuhimbise Wilson , Atwine Daniel , Kaggwa Fred , Musiimenta Angella 
Published: December 2021

Abstract
Background

Despite some global progress in the implementation of the public-private mix for Tuberculosis care, the engagement of private healthcare providers remains wanting especially in high incidence countries such as Uganda. Although mobile health technologies are low-cost approaches that can enhance Tuberculosis care, there is a dearth of research about their application in fostering public-private mix.
Objective

To explore the potentials of mobile health technologies in fostering public-private mix for Tuberculosis care in Uganda.
Methods

This was a qualitative study design that involved in-depth interviews with 13 key informants (private healthcare workers) purposively selected between June and July 2020 due to their active involvement in Tuberculosis care from four private hospitals in Mbarara City. The interviews were transcribed and coded to identify key themes for analysis using content analysis.
Results

Mobile Health technologies (such as mobile apps, text messages) have the potential to map and link patients from private hospitals to the referral units, support patient medication adherence, notify and report Tuberculosis cases to the Ugandan Ministry of Health, and enhance patient care and monitoring.
Conclusion

Mobile Health technologies have the potential to revolutionize Tuberculosis care by establishing a centralized pathway for linking the referred patients from private hospitals to public hospitals. Future research should focus on assessing the utilization of mobile health technologies in enhancing access to referral units by presumptive Tuberculosis patients referred from private hospitals in low-resource settings.
Stability of B2 compounds: Role of the M point phonons
Authors: Ono Shota , Kobayashi Daigo 
Published: December 2021

Abstract
Although many binary compounds have the B2 (CsCl-type) structure in the thermodynamic phase diagram, an origin of the structural stability is not understood well. Here, we focus on 416 compounds in the B2 structure extracted from the Materials Project, and study the dynamical stability of those compounds from first principles. We demonstrate that the B2 phase stability lies in whether the lowest frequency phonon at the M point in the Brillouin zone is endowed with a positive frequency. We show that the interatomic interactions up to the fourth nearest neighbor atoms are necessary for stabilizing such phonon modes, which should determine the minimum cutoff radius for constructing the interatomic potentials of binary compounds with guaranteed accuracy.

Published: December 2021

Abstract
Background : There is strong evidence to support the association between bullying and the onset of mental health conditions in students with ASD. In Taiwan, seventh grade marks the first year in middle school after elementary school. It is also a period when peers tend to affiliate with one another to perform bullying behaviors to establish status among the peer group. Therefore, it is considered one of the most challenging times for students with ASD due to several adjustments within the school environment and the developmental changes that arise at this age.. To assess the association between school environment and bullying victimization among students with autism spectrum disorder (ASD) studying in regular classes in the first year of middle school. Methods: Data were obtained from the Special Needs Education Longitudinal Study database located in the Survey Research Data Archive of Academia Sinica. One hundred and eighty-four seventh-graders with ASD in regular classes across Taiwan were included in the analysis. The primary variables under study were whether they had experienced social exclusion, insults or teasing, extortion, or sexual harassment over the past semester.Results: Participants with a higher positive friendship quality (P = 0.027) and who had received more peer support upon encountering difficulties in school (P = 0.041) were less likely to experience social exclusion. Participants with higher positive friendship quality (P = 0.001) and a more positive learning environment in the classroom (P = 0.031) were less likely to have experienced insults or teasing. However, participants with more friends were more likely to be extorted (P = 0.015) and sexually harassed (P = 0.001) than those with fewer friends. Furthermore, participants in regular classes on a part-time basis were 2.59 times more likely to report sexual harassment than those in regular classes on a full-time basis (P = 0.021). Conclusions : This study suggests that a supportive school environment reduces the likelihood that seventh-graders with ASD are bullied. Clinicians should consider the association between the school environment and bullying victimization among adolescents with ASD in regular classes during their first year of middle school.
Mechanical Properties of Bamboo And Their Use In Fishing Rods
Authors: Nishiyama Ryo , Sato Motohiro 
Published: December 2021

Abstract
Bamboo has historically been used in Japan as a structural material and for building tools such as fishing rods owing to its remarkable structural properties. In recent years, the materials used for manufacturing fishing rods have changed greatly owing to the development of composite materials; however, the basic slender tapered hollow cylindrical fishing rod design has remained unchanged throughout the long history of fishing. However, the mechanical rationale behind this structural design has not yet been sufficiently verified, and this study clarifies this. The analysis was performed by solving the nonlinear bending equation of a slender tapered cantilever beam with a concentrated load at the tip, which causes large deflection, using the Runge–Kutta method. The deflection curves and bending stresses were obtained, and the structural design to minimize the stresses was explored. Our results may prove useful for bamboo-inspired bionic design and bring to light our ancestors’ deep knowledge of natural materials and their advanced technological capabilities.
Lipid A modification-induced colistin-resistant Klebsiella variicola from healthy adults
Authors: Kim Sun Ju , Jo Jeongwoo , Ko Kwan Soo 
Published: December 2021

Abstract
We identified two Klebsiella variicola isolates from fecal samples: one is colistin-resistant, and another is colistin-susceptible. The colistin-resistant K. variicola isolate showed no mutations in phoPQ, pmrAB, and mgrB, and crrAB and mcr were not identified. However, its phoQ and pbgP expression was significantly higher and amino-arabinosylated lipid A with hexa-acylated species in lipopolysaccharide was identified.

Authors: Ibrahim Ehab A. , Selim El-Metwally M. 
Published: December 2021

Abstract
The accumulation of trace metals in vegetable field soils is of expanding worry because of the potential health hazards and its detrimental effects on soil ecosystems. To investigate the state of trace metal pollution in vegetable field soils, 60 surface soil samples were collected from vegetable fields across the Eastern Nile Delta region, Egypt. The results explained that the concentrations of Cu, Mn and Ni were lesser than their corresponding background values, while the concentrations of Cd, Co, Pb and Zn were exceed their background values. The pollution indices showed that the study soil experienced low to moderate contamination, and the Cd and Cr contamination was serious. The hazard index values of nine trace metals signified that there no adverse non-carcinogenic risk for adults and children. The carcinogenic risk of Cd, Co, Ni and Pb for both age groups was within the acceptable limits, while Cr had critical carcinogenic hazard to children. Overall, the quality of studied soils is relative safety, although some samples impose serious pollution problems by Cd and Cr. Thus, properly monitor trace metals and soil management action should be applied to reduce further soil pollution in vegetable fields in the Eastern Nile Delta.

Published: December 2021

Abstract
Background: One option in total knee arthroplasty (TKA) perioperative pain management is femoral nerve block (FNB). Its association with quadriceps weakness has led to a focus on adductor canal block (ACB), with the aim of avoiding weakness in adjacent muscles. This study reviewed cases at our institution. Methods: In this pilot non-blinded study, nerve block (FNB or ACB) was performed under ultrasonic guidance after induction of general anesthesia, with an initial bolus followed by continuous levobupivacaine infusion into the perineurium as needed until postoperative day (POD) 2 or 3. Pain levels and falls/near-falls with knee-buckling were monitored from POD 1 to POD 3. The score on the manual muscle test, MMT (0 to 5, 5 being normal), of the patients who had been able to ambulate on POD 1, was investigated. Results: A total of 73 TKA cases, 37 FNB and 36 ACB, met the inclusion criteria. Episodes of near-falls in the form of knee-buckling were witnessed in 14 (38%) cases in the FNB group and in 4 (11%) in the ACB group (p = 0.0068). In the ACB group, 81.1% of patients were able to ambulate with parallel bars on POD 1, while only 44.4% of FNB patients could do so (p = 0.0019). The quadriceps MMT values of patients able to ambulate with parallel bars on POD 1 in the ACB group was 2.82, significantly higher than 1.97 in the FNB group (p = 0.0035). There were no significant differences in pain as measured with a numerical rating scale (NRS) through POD 3. Conclusion: Compared to FNB, ACB was associated with significantly less knee-buckling and earlier initiation of ambulation post-TKA, with better quadriceps muscle strength. These findings support the use of ACB as the anesthesia method of choice for TKA.
Discriminating Chiral Insertions from BSM for the Muon (g-2) by non-Abelian Zero Modes
Authors: Maalouf Hani W. 
Published: December 2021

Abstract
A sorting out method, between the New Physics and as vs. the Lepton Flavor Violated Chiral insertion is exposed, interpreting so the Light-by-Light scattered amplitude deviation in the muon magnetic moment, with a novel 2-color instead of 3-color in diagrams projective polarizations. The calculation is done using an extension-detention of the muon resonance interaction internal lines (which may be generically of a non-QCD nature)such its modes’ phonons decompose into instantons while the helicities are to meet the imposed polarizations. A confirmation comes out from a non-applicability of the Landau Gauge, to the one of the cases, the tri-vector-mode, giving it a double pole in its Goldstone propagator, vs. its truth in the Sudakov type with a single pole mode Goldstone propagator.The fits between expansions of the phonon derived from slicing’s, and the instanton derived from inverse arguments of differently coupled cosine’s, are surprisingly proportional to their projected (2 to 3 in their extended diagrams) normalization factors paving ways into a BSM popped up selectivity method.

Authors: Sivaramanan Sivakumaran , Kotagama Sarath Wimalabandara 
Published: December 2021

Abstract
Background: Environmental problems are on a hike. The study provides evidenceof the links between man-made environmental issues based on cause-and-effect relationship from real-world examples. For instance, man-made climate change is caused primarily by deforestation, draining of wetlands, intensive farming, and air pollution (greenhouse gas emission). Also, each of these problems, air pollution for instance, is caused by intensive farming, burning of fossil fuels (because of the global energy crisis), urbanization, and methane emission from solid waste dumps. Deforestation is mainly caused by increasedhuman population, poverty, overexploitation of natural resources, urbanization, mining minerals, intensive farming, the establishment of dams, wildfires during El Niño, acid rain, and global warming (cyclic as cause and effect). Besides, every man-made environmental problem may cause various other environmental problems, such as air pollution causes ocean acidification, ozone depletion, acid rain, disease, and visual pollution (smog). Similarly, deforestation causes biodiversity loss, land degradation, and human-animal conflict.Results: About 252 links were examined among 40 identified environmental issues. In this web, certain causative environmental problems were established as “keystone links”. Possible keystone environmental problems were identified from the concept map based on the criteria given by the following approach, when mitigating a man-made environmental problem, if it results in the permanent disappearance of one or more man-made environmental problems, then that mitigated problem can be considered as a possible keystone environmental problem in a hypothetical situation where human adaptability factors such as economic, social, and political factors are absent.Conclusions: Eight man-made environmental problems were found as keystones such as air pollution, deforestation, population explosion, overexploitation of natural resources, global energy crisis, intensive farming, water pollution-water scarcity, and urbanization-urban sprawl-settlements.

Abstract
Background: The multidisciplinary treatment including induction chemotherapy plus conversion surgery (CS) has attracted attention as a new strategy to improve the outcome of metastatic gastric cancer (MGC). However, it is unclear which patients achieve a good response to chemotherapy and successful CS. Tumor-infiltrating immune cells (TIICs) have been reported to be both prognostic and predictive biomarkers not only in immunotherapy but also in chemotherapy in many cancer types. However, there have been no reports on the usefulness of TIICs as biomarkers in conversion surgery for MGC. The aim of the present study was to evaluate the association between the TIICs and treatment outcome for the multidisciplinary treatment in MGC.Methods: We retrospectively analyzed 68 MGC patients who received docetaxel plus cisplatin plus S-1 (DCS) therapy between April 2006 and March 2019 in our institute. The number of tumor-infiltrating CD4+, CD8+, Foxp3+lymphocytes, CD68+, CD163+macrophages in pre-treatment endoscopic biopsy samples were evaluated to investigate their predictive value for multidisciplinary treatment.Results: 50 patients underwent CS following DCS therapy (CS group), whereas 18 patients underwent DCS therapy alone (non-CS group). The MST of CS group was 33.3 months, which was significantly longer than the MST of 9.0 months in non-CS group (p<0.01). The number of CD163+macrophages was extracted as an independent prognostic factor for overall survival in all patients. There were more cases of high infiltration of CD 163+macrophages in non-CS group than in CS group. Furthermore, in CS group, pathological responders to DCS therapy showed low infiltration of CD 163+ macrophages, and high infiltration of CD8+lymphocyte. CD 163 low group showed a significant prolonged survival compared with CD163 high group in patients who underwent CS (p=0.02).Conclusions: The pre-treatment CD163+macrophages infiltration would be a pivotal biomarker for predicting prognosis and pathological response to multidisciplinary treatment among TIICs in MGC.Thus, for patients with low CD163+macrophage infiltration in pre-treatment biopsy sample, diagnostic imaging should be performed frequently during chemotherapy to avoid missing the optimal timing for CS, and CS should be aggressively considered as a treatment option if curative resection is deemed feasible.
