Advocacy on the outside: Advancing support for system‐impacted students through grassroots leadership
Authors: Yücel Elif 
Published: June 2023

AbstractCommunity College Reentry Programs (CCRPs) are campus‐based programs that serve formerly incarcerated students by providing targeted services attuned to their needs. Currently, there are 62 community colleges in California that have CCRPs. While emerging research has begun to examine the experiences of students in these programs, little is known about the staff who lead them. This study uses a grassroots leadership perspective to examine how CCRP staff lead for organizational change. Through the presentation of two case narratives of CCRPs, I show how staff lead reform efforts towards advancing justice and equity for their students on campus and in the community. My findings have implications for strengthening aid for these programs and better supporting their staff.
Meeting the moment: Inside‐outside strategies as a critical element to contemporary transformative leadership
Authors: Tapia‐Fuselier Nicholas 
Published: June 2023

AbstractConsidering the range of social justice issues at the forefront of 21st Century American life, and the ways in which these issues manifest on community college campuses, leaders must examine their responsibility to confront inequities and promote change. Transformative leadership is a style of leading that explicitly acknowledges inequities within and outside of an institution, embraces collective action, and imagines possibilities for change. In this chapter, I connect the concept of transformative leadership to the historical and contemporary legacy of activism. This connection leads me to propose inside‐outside strategies as a necessary element to the practice of transformative leadership in order to meet the current sociopolitical moment.
Incidental craniovertebral junction schwannoma: Surgical or radiosurgical management?
Authors: Umana Giuseppe Emmanuele , Passanisi Maurizio , Chaurasia Bipin , Scalia Gianluca 
Published: June 2023

Key Clinical MessageCraniovertebral junction (CVJ) schwannomas are rare tumors, showing direct involvement of the atlanto‐occipital and atlanto‐axial joints. Microsurgical removal is the standard of care to improve symptoms and local control, but stereotactic radiosurgery (SRS) is an option. Both, surgery, and SRS, may show risks of severe complications. A 41‐year‐old male was referred to our department after incidental finding of a right‐sided C1 tumor. A CT angiogram with 3D reconstructions showed the close relationship between the tumor and the right vertebral artery (VA). A post‐contrast enhancement MRI revealed the presence of an extradural mass, sited at the level of the CVJ, mainly at the level of the right articular mass of C1. After multidisciplinary assessment, involving the gamma‐knife and neurosurgical teams, we performed a microsurgical resection of the tumor. Histology confirmed the diagnosis of schwannoma. At 1 year follow‐up the patient is stable, with no recurrence of the tumor. CVJ schwannoma's current standard of care is surgical resection, but longitudinal studies are required, and should promoted promptly since the recent introduction of the new version of GKSRS that allow the treatment of CVJ's lesions.

AbstractRaising the energy density of lithium‐ion batteries (LIBs) through the operation of high‐voltage cathodes presents a challenge in terms of practical use due to electrolyte degradation. Consequently, it is imperative to explore new materials to circumvent this issue. In this study, a combination of tris(trimethylsilyl) phosphite (TMSPi) and lithium difluoro(oxalato)borate (LiDFOB) is presented as film‐forming additives in a conventional LiPF6‐containing carbonate‐based electrolyte solution in high‐voltage LiNi0.5Mn1.5O4‐graphite full cells. At high voltage, TMSPi oxidizes on the LiNi0.5Mn1.5O4 (LNMO) cathode surface prior to the decomposition of electrolyte solvents, promoting the formation of a stable cathode electrolyte interphase (CEI) layer. In tandem, given that LiDFOB has a lower reduction potential than ethylene carbonate (EC), it has the possibility of forming a solid electrolyte interphase (SEI) on the graphite anode surface. Combining the two additives was found to suppress the degradation of the electrolyte to a large extent. Among the investigated concentration of the additives, the combination of 1 wt. % TMSPi and 2 wt. % LiDFOB added to LP40 electrolyte exhibits improved capacity retention of 80 % after 400 cycles at 0.3 C, compared to the electrolyte with no additive with 67 % capacity retention over the same period. Thereby, the combination of TMSPi with LiDFOB provides an improvement for high voltage LIBs.

Published: June 2023

AbstractElectrocatalytic CO2 reduction reaction (CO2RR) is a promising and green approach for reducing atmospheric CO2 concentration and achieving high‐valued conversion of CO2 under the carbon‐neutral policy. In CO2RR, the dual‐site metal catalysts (DSMCs) have received wide attention for their ingenious design strategies, abundant active sites, and excellent catalytic performance attributed to the synergistic effect between dual‐site in terms of activity, selectivity and stability, which plays a key role in catalytic reactions. This review provides a systematic summary and detailed classification of DSMCs for CO2RR, describes the mechanism of synergistic effects in catalytic reactions, and also introduces in situ characterization techniques commonly used in CO2RR. Finally, the main challenges and prospects of dual‐site metal catalysts and even multi‐site catalysts for CO2 recycling are analyzed. It is believed that based on the understanding of bimetallic site catalysts and synergistic effects in CO2RR, well‐designed high‐performance, low‐cost electrocatalysts are promising for achieving CO2 conversion, electrochemical energy conversion and storage in the future.
The “How” and “Where” Behind the Functionalization of Graphene Oxide by Thiol‐ene “Click” Chemistry
Authors: Piñeiro‐García Alexis , Semetey Vincent 
Published: June 2023

AbstractGraphene oxide (GO) is a 2D nanomaterial with unique chemistry due to the combination of sp2 hybridization and oxygen functional groups (OFGs) even in single layer. OFGs play a fundamental role in the chemical functionalization of GO to produce GO‐based materials for diverse applications. However, traditional strategies that employ epoxides, alcohols, and carboxylic acids suffer from low control and undesirable side reactions, including by‐product formation and GO reduction. Thiol‐ene “click” reaction offers a promising and versatile chemical approach for the alkene functionalization (−C=C−) of GO, providing orthogonality, stereoselectivity, regioselectivity, and high yields while reducing by‐products. This review examines the chemical functionalization of GO via thiol‐ene “click” reactions, providing insights into the underlying reaction mechanisms, including the role of radical or base catalysts in triggering the reaction. We discuss the “how” and “where” the reaction takes place on GO, the strategies to avoid unwanted side reactions, such as GO reduction and by‐product formation. We anticipate that multi‐functionalization of GO via the alkene groups will enhance GO physicochemical properties while preserving its intrinsic chemistry.

AbstractThe first neutral and cationic Mo imido alkylidene cyclic alkyl amino carbene (CAAC) complexes of the general formulae [Mo(N−Ar)(CHCMe2Ph)(X)2(CAAC)] and [Mo(N−Ar)(CHCMe2Ph)(X)(CAAC)][B(ArF)4] (X=Br, Cl, OTf, OC6F5; CAAC=1‐(2,6‐iPr2‐C6H3)‐3,3,5,5‐tetramethyltetrahydropyrrol‐2‐ylidene) have been synthesized from molybdenum imido bishalide alkylidene DME precursors. Different combinations of the imido and “X” ligands have been employed to understand synthetic peculiarities. Selected complexes have been characterized by single‐crystal X‐ray analysis. Due to the pronounced σ‐donor/π‐acceptor characteristics of CAACs, the corresponding neutral and cationic molybdenum imido alkylidene CAAC complexes do not require the presence of stabilizing donor ligands such as nitriles. Calculations on the PBE0‐D3BJ/def2‐TZVP level for PBE0‐D3BJ/def2‐SVP optimized geometries revealed partial charges at molybdenum similar to the corresponding molybdenum imido alkylidene N‐heterocyclic carbene (NHC) complexes with a slightly higher polarization of the molybdenum alkylidene bond in the CAAC complexes. All cationic complexes have been tested in olefin metathesis reactions and showed improved activity compared to the analogous NHC complexes for hydrocarbon‐based substrates, allowing for turnover numbers (TONs) up to 9500 even at room temperature. Some Mo imido alkylidene CAAC complexes are tolerant towards functional groups like thioethers and sulfonamides.

Published: June 2023

AbstractA parallel paired electrosynthetic method, coupling electrocarboxylation incorporating CO2 into ketone, imine, and alkene with alcohol oxidation or oxidative cyanation of amine, was developed for the first time. Various carboxylic acids as well as aldehyde/ketone or α‐nitrile amine were prepared at the cathode and anode respectively in a divided cell. Its utility and merits on simultaneously achieving high atom‐economic CO2 utilization, elevated faradaic efficiency (FE, total FE of up to 166 %), and broad substrate scope were demonstrated. The preparation of pharmaceutical intermediates for Naproxen and Ibuprofen via this approach proved its potential application in green organic electrosynthesis.

ABSTRACTAnalytic treatment interruption (ATI) is scientifically necessary in HIV‐remission (“cure”) studies to test the effects of new interventions. However, stopping antiretroviral treatment poses risks to research participants and their sexual partners. Ethical debate about whether and how to conduct such studies has largely centered on designing risk‐mitigation strategies and identifying the responsibilities of research stakeholders. In this paper, we argue that because the possibility of HIV transmission from research participants to partners during ATI cannot practicably be eliminated—that is, it is ineliminable—the successful conduct of such trials ultimately depends on relationships of trust and trustworthiness. We describe our experiences with conducting and studying HIV‐remission trials with ATI in Thailand to examine the strengths, complexities, and limitations of the risk‐mitigation and responsibility approaches and to explore ways in which the building of trust—and trustworthiness—may help enhance the scientific, practical, and ethical dimensions of these trials.

AbstractObjectiveThe objective of this study was to investigate the predictive value of sex, age, body mass index (BMI), Eating Disorder Examination (EDE) score, social risk factors, and psychiatric comorbidities for hospitalization and hospitalization duration among children and adolescents suffering from eating disorders.MethodThis prospective cohort study involved 522 consecutive patients who had been referred to a specialized eating disorder unit between January 1, 2009 and December 31, 2015; participants were followed up until August 1, 2016 by medical records. We used regression analyses to evaluate the prognostic value of sex, age, BMI, EDE, eating disorder diagnoses, social risk factors, and psychiatric comorbidities concerning inpatient hospitalization and hospitalization duration.ResultsWe found that younger age, higher EDE global score, lower BMI percentile, anorexia nervosa, a higher number of social risk factors, and the presence of diagnosed self‐harm increased the odds of being hospitalized, while being female and having a comorbid autism spectrum condition increased the duration of hospitalization. No other psychiatric comorbidity was found to significantly predict hospitalization or duration of hospitalization.DiscussionThe odds of being hospitalized were predicted by the severity of anorexia nervosa and indicators of social risk factors in the family, whereas the duration of hospitalization was predicted by having a comorbid autism spectrum condition, indicating a difference between the factors affecting the risk of hospitalization and the factors affecting the duration of hospitalization. This calls for further exploration of tailored treatments for eating disorders.Public Significance StatementThis study finds that hospitalization for an eating disorder is predicted by the severity of the illness, self‐harm, and social risk factors. Duration of hospitalization is predicted by having a comorbid autism spectrum condition. These findings indicate that the treatment of eating disorders may require different treatment approaches depending on the presentation of the individual patient to reduce both the need for hospitalization and the length of inpatient stay.
Ecological response of an umbrella species to changing climate and land use: Habitat conservation for Asiatic black bear in the Sichuan‐Chongqing Region, Southwestern China

Published: June 2023

AbstractClimate and land use changes are increasingly recognized as major threats to global biodiversity, with significant impacts on wildlife populations and ecosystems worldwide. The study of how climate and land use changes impact wildlife is of paramount importance for advancing our understanding of ecological processes in the face of global environmental change, informing conservation planning and management, and identifying the mechanisms and thresholds that underlie species' responses to shifting climatic conditions. The Asiatic black bear (Ursus thibetanus) is a prominent umbrella species in a biodiversity hotspot in Southwestern China, and its conservation is vital for safeguarding sympatric species. However, the extent to which this species' habitat may respond to global climate and land use changes is poorly understood, underscoring the need for further investigation. Our goal was to anticipate the potential impacts of upcoming climate and land use changes on the distribution and dispersal patterns of the Asiatic black bear in the Sichuan‐Chongqing Region. We used MaxEnt modeling to evaluate habitat vulnerability using three General Circulation Models (GCMs) and three scenarios of climate and land use changes. Subsequently, we used Circuit Theory to identify prospective dispersal paths. Our results revealed that the current area of suitable habitat for the Asiatic black bear was 225,609.59 km2 (comprising 39.69% of the total study area), but was expected to decrease by −53.1%, −49.48%, and −28.55% under RCP2.6, RCP4.5, and RCP8.5 projection scenarios, respectively. Across all three GCMs, the distribution areas and dispersal paths of the Asiatic black bear were projected to shift to higher altitudes and constrict by the 2070s. Furthermore, the results indicated that the density of dispersal paths would decrease, while the resistance to dispersal would increase across the study area. In order to protect the Asiatic black bear, it is essential to prioritize the protection of climate refugia and dispersal paths. Our findings provide a sound scientific foundation for the allocation of such protected areas in the Sichuan‐Chongqing Region that are both effective and adaptive in the face of ongoing global climate and land use changes.

Published: June 2023

AbstractIn this paper, an attempt has been made to arrive at sufficiently realistic estimates of the average shear‐wave velocity in the top 30 m of the ground () for 200 strong motion recording sites spread over the Himalayas, adjoining Indo‐Gangetic plains and northeast Indian regions. This is achieved by extending the application of the horizontal to vertical spectral ratio (HVSR) method for the strong motion recording sites with a limited number of records. The knowledge of surface geology at the recording sites and the estimates based on the topographic slope method has been utilized as supplementary information to arrive at a good first‐order approximation of for the sites with a single record also. A total of 669 three‐component acceleration records have been obtained at the 200 sites considered from 158 different earthquakes in the magnitude range of 2.3–7.9 during 1986–2015. It had not been possible to use this database fruitfully due to lack of the required site characterization. Compared to the costly and time‐taking field studies required for the estimation of exact site‐specific values, the proposed scheme can be considered to provide a convenient methodology for obtaining sufficiently reliable approximations of from the recorded strong motion data. The values obtained in this study are found to be in very good agreement with the site‐specific experimental values available for 29 of the sites, establishing the validity of the proposed scheme. An alternative site characterization is also provided in terms of the site soil and the local geological conditions, both defined in terms of three categories specified by indicator variables with values of 0, 1 and 2. Lee and Trifunac have illustrated that this characterization has stronger correlation with the ground motion amplitudes than the as well as the NEHRP site classes based on broad intervals of . The site characterization of the 200 strong motion recording sites in the present study will find useful applications in developing region‐specific empirical ground motion prediction equations with the site amplification effects modeled realistically and in selecting suitable equations from the published literature using score‐based data‐driven methods.

AbstractNonhematopoietic lymph node stromal cells (LNSCs) regulate lymphocyte trafficking, survival, and function for key roles in host defense, autoimmunity, alloimmunity, and lymphoproliferative disorders. However, the study of LNSCs in human diseases is complicated by a dependence on viable lymphoid tissues, which are most often excised prior to establishment of a specific diagnosis. Here, we demonstrate that cryopreservation can be used to bank lymphoid tissue for the study of LNSCs in human disease. Using human tonsils and lymph nodes (LN), lymphoid tissue fragments were cryopreserved for subsequent enzymatic digestion and recovery of viable nonhematopoietic cells. Flow cytometry and single‐cell transcriptomics identified comparable proportions of LN stromal cell types in fresh and cryopreserved tissue. Moreover, cryopreservation had little effect on transcriptional profiles, which showed significant overlap between tonsils and LN. The presence and spatial distribution of transcriptionally defined cell types were confirmed by in situ analyses. Our broadly applicable approach promises to greatly enable research into the roles of LNSCs in human disease.

AbstractWith the aim of achieving bioorthogonal intracellular catalysis, a library of platinum(II) complexes was synthesized. Their non‐toxicity to living cells was demonstrated and their catalytic activity was evaluated on a cyclization reaction leading to a highly fluorescent coumarin. None of the platinum complexes showed any catalytic activity for coumarin synthesis. Still, we demonstrated that the silver salt AgSbF6commonly used to ‘activate’ metal catalysts by removing a chloride is a very efficient catalyst for the studied intramolecular cyclization reaction.
Graph neural networks for image‐guided disease diagnosis: A review

Published: June 2023

AbstractMedical imaging is playing an increasingly crucial role in disease diagnosis. Numerous deep learning‐based methods have been developed for image‐guided automatic disease diagnosis. Most of the methods have harnessed conventional convolutional neural networks, which are directly applied in the regular image domain. However, some irregular spatial patterns revealed in medical images are also critical to disease diagnosis, since they can describe latent relations in different image regions of a subject (e.g., different focal lesions in an image) or between different groups (e.g., Alzheimer's disease and healthy control). Therefore, how to exploit and analyze irregular spatial patterns and their relations has become a research challenge in the field of image‐guided disease diagnosis. To address this challenge, graph neural networks (GNNs) are proposed to perform the convolution operation on graphs. Graphs can naturally represent irregular spatial structures. Because of their ability to aggregate node features, edge features, and graph structure information to capture and learn hidden spatial patterns in irregular structures, GNN‐based algorithms have achieved promising results in the detection of various diseases. In this paper, we introduce commonly used GNN‐based algorithms and systematically review their applications to disease diagnosis. We summarize the workflow of GNN‐based applications in disease diagnosis, ranging from localizing the regions of interest and edge construction to modeling. Furthermore, we discuss the limitations and outline potential research directions for GNNs in disease diagnosis.
