Authors: Surmann Hartmut , Pervölz Kai , Nüchter Andreas , Lingemann Kai , Hertzberg Joachim , Hennig Matthias 
Published: October 2005

Summary
Deploying rescue workers in an urban setting is often a perilous, time-, power-, and force-consuming job, and robot systems to assist in this effort are needed. A fundamental task for rescuer is to localize and salvage injured persons. To this end, robotic systems are used for mapping a site and for remote inspection of suspicious objects. The mobile robot Kurt3D is the first rescue robot that is capable of mapping its environment in 3D and self localize in all six degrees of freedom, i. e., considering its x, y and z positions and the roll, yaw and pitch angles. This capability allowed the small robot to win the Vice World Championship at the RoboCup Rescue competition 2004 at Lisbon.

Data Mining: The Next Generation (Data Mining: Die nächste Generation)
Authors: Freytag Johann-Christoph , Ramakrishnan Raghu , Agrawal Rakesh 
Published: October 2005

Summary
Data Mining has enjoyed great popularity in recent years, with advances in both research and commercialization. The first generation of data mining research and development has yielded several commercially available systems, both stand-alone and integrated with database systems, produced scalable versions of algorithms for many classical data mining problems and introduced novel pattern discovery problems. In July 2004 researchers from a variety of backgrounds assembled at the Dagstuhl Conference Center in Germany for a workshop to re-assess the current directions of the field, to identify critical problems that require attention, and to discuss ways to increase the flow of ideas across the different disciplines that Data Mining has brought together. The workshop did not seek to draw up an agenda for the field of data mining. Rather, it offers the participants' perspective on two technical directions – compositionality and privacy – and describes some important application challenges which drove the discussion.

Between anti‐Semitism and Islamophobia: Some thoughts on the new Europe
Authors: Bunzl Matti 
Published: October 2005

ABSTRACTThe apparent resurgence of hostility against Jews has been a prominent theme in recent discussions of Europe. At the same time, the adversities of the Muslim populations on the continent have received increasing attention as well. In this article, I attempt a historical and cultural clarification of the key terms in this debate. I argue against the common impulse to analogize anti‐Semitism and Islamophobia. Instead, I offer an analytic framework that locates the two phenomena in different projects of exclusion. Anti‐Semitism was invented in the late 19th century to police the ethnically pure nation‐state; Islamophobia, by contrast, is a formation of the present, marshaled to safeguard a supranational Europe. Whereas traditional anti‐Semitism has run its historical course with the supersession of the nation‐state, Islamophobia threatens to become the defining condition of the new Europe.
Edward Said and the political present
Authors: Abu El‐Haj Nadia 
Published: October 2005

ABSTRACTThis article offers a reading of Edward Said's legacy. It engages Said's scholarly and political insights, on the one hand, and his vision of and life as an intellectual, on the other hand. The article focuses on his broader conceptual and methodological interventions, his analysis of the politics of empire (in the Middle East), and his passionate attachment to the question of Palestine. It also contextualizes Said's work in light of the contemporary political moment, arguing that he and that for which he is seen to stand have emerged as key flash points in the latest U.S. culture wars.
Between heritage and countermemory: Varieties of historical representation in a West German community
Authors: Eidson John R. 
Published: October 2005

ABSTRACTContrasting views of the past are often understood in terms of dichotomies (e.g., hegemonic–counterhegemonic and regressive–progressive), but ethnographic data gathered in a German community suggest the need for a more differentiated approach. The public presentation of history in that community corresponds to one of three conventions: (1) the commemoration of the founding of local institutions by their members, (2) “hometown history,” an avocation of the local bourgeoisie, and (3) citizens' initiatives for coming to terms with the Nazi past. German‐area specialists have tended to dismiss the first two types and to valorize the third, but different representations of the past in the present are best viewed as varieties of symbolic capital, which members of different social groups employ in the institutional settings to which they have access and in which they are authorized to play active roles.
An “impossible” transmission: Youth religious memories in Guinea–Conakry
Authors: Berliner David 
Published: October 2005

ABSTRACTMemory, persistence, and cultural transmission are hot topics in anthropology today. Contributing to an increasing anthropological interest in youth agency, in this article I invite readers to look at youth as a crucial site for understanding issues of religious memory and cultural transmission. In the past five decades, Bulongic people (Guinea–Conakry) have undergone significant religious changes caused by the introduction of Islam, which has led to the official disappearance of pre‐Islamic rituals. In this article, I explore how young Bulongic remember a pre‐Islamic past that they have never experienced. I argue that, to understand how they assimilate and perpetuate this religious heritage, one must examine the subtle processes of intergenerational transmission through which their memories are dynamically shaped.
Encounters with the “peasant”: Memory work, masculinity, and low fertility in Italy
Authors: Krause Elizabeth L. 
Published: October 2005

ABSTRACTThe peasant in Italy has all but vanished as an exemplar of an economic way of life but as a social figure has relevance to trends such as the transformation to small families. Ethnographic “encounters” provide the basis for my explorations into the trauma and meaning of the historical experiences that find expression in Italian women's low fertility rates. Current family‐making practices have resulted from historical adjustments deeply linked to economic shifts that involved the unraveling of a patriarchal hierarchy and necessitated a subsequent reworking of gendered subjects situated in new socioeconomic conditions. An ethnographic focus on memory work reveals that the social figure of the peasant persists in meaningful ways that shape people's family‐making practices.
Family firms amidst the creative destruction of capitalism
Authors: Marcus George E. 
Published: October 2005

ABSTRACTIn terms of anthropology's past interests, the study of family firms seems a “natural” way into the ethnography of contemporary capitalism. True, but as Sylvia Yanagisako's rich and sensitive study demonstrates, this is so by productively frustrating central ideas in anthropology like “culture” and “kinship” without resolution in alternative concepts.
Image and instrumentality in a Xavante politics of existential recognition: The public outreach work of EtÉnhiritipa Pimentel Barbosa
Authors: Graham Laura R. 
Published: October 2005

ABSTRACTThis analysis of one Xavante group's innovative projects to represent Xavante culture to nonindigenous audiences reveals multiple and complex perceptions of instrumentalities as well as political goals. Unlike many contemporary Native (Amazonian and other) groups that use aspects of their culture to attract support and achieve concrete political goals, local objectives are relatively abstract and future oriented, having to do with public “image” and “existential recognition.” Analysis illustrates that local ideas about indigenous cultural displays aimed primarily at nonindigenous audiences, including “identity politics” and apparently straightforward cultural commodification, may not neatly correspond with anthropologists' or other outsiders' expectations. Overly narrow interpretive foci may cause anthropologists to overlook the potential for multiple and complex objectives and a diversity of locally significant dimensions.
Global movements and local historical events: Itelmens of Kamchatka appeal to the United Nations
Authors: Koester David 
Published: October 2005

ABSTRACTIn this article, I examine the institutional, cultural, and discursive foundations of a historical event. I explicate global, transnational, national, intercultural, ethnic, regional, local, and personal realms of understanding as well as a range of discursive and pragmatic strategies as they came into play in a schoolroom meeting that led to the writing of a letter to the United Nations for help. The case presented is that of a group of people in a small, majority‐indigenous village in Kamchatka in the Russian Far East, who, in 1993, after the collapse of the Soviet government and its support network, decided to turn to the United Nations for help.
Eritrea on‐line: Diaspora, cyberspace, and the public sphere
Authors: Bernal Victoria 
Published: October 2005

ABSTRACTFor Eritreans in diaspora, identities are deterritorialized, one's most pressing communication may be with far‐flung strangers in cyberspace, and one's political engagement is centered on a distant homeland. Eritrean experiences, thus, seem to bring together various qualities that scholars have been grappling with in trying to chart the implications of the infotech revolution and life on‐line, in seeking to understand processes of transnationalism and globalization, and in charting the elusive construction of community in the postmodern age. Through an analysis of the social history of www.dehai.org, a website developed by Eritreans in diaspora, I explore the ways that new forms of technological and geographical mobility are changing the conditions not just of capitalist production but also of knowledge production and the constitution of publics, public spheres, communities, and nations.
Culture, state, and security in Europe: The case of citizenship and integration policy in Estonia
Authors: Feldman Gregory 
Published: October 2005

ABSTRACTIn this article, I examine how a territorial imaginary conflating culture, territory, nation, and security allows “elites of statecraft” in Europe to frame citizenship and integration policy as (inter)national security matters. Focusing on post‐Soviet Estonia, I argue that this imaginary legitimized the denial of citizenship to Soviet‐era Russian speakers and enabled the government's integration policy objective of creating the “Estonian cultural domain.” Drawing on historical, archival, and ethnographic research, I demonstrate how the invocation of national security justified these events and how the territorial imaginary structured the making of integration policy from the 1991 reestablishment of independence to E.U. accession in 2004.

ImportanceStudies suggest a higher risk of schizophrenia diagnoses in Black vs White Americans, yet a systematic investigation of disparities that include other ethnoracial groups and multiple outcomes on the psychosis continuum is lacking.ObjectiveTo identify ethnoracial risk variation in the US across 3 psychosis continuum outcomes (ie, schizophrenia and other psychotic disorders, clinical high risk for psychosis [CHR-P], and psychotic symptoms [PSs] and psychotic experiences [PEs]).Data SourcesPubMed, PsycINFO and Embase were searched up to December 2022.Study SelectionObservational studies on ethnoracial differences in risk of 3 psychosis outcomes.Data Extraction and SynthesisPreferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were followed. Using a random-effects model, estimates for ethnoracial differences in schizophrenia and PSs/PEs were pooled and moderation by sampling and setting was determined, along with the assessment of heterogeneity and risk of bias.Main Outcomes and MeasuresRisk of schizophrenia and other psychotic disorder, CHR-P, and conversion to psychosis among CHR-P and PSs/PEs.ResultsOf 64 studies in the systematic review, 47 were included in the meta-analysis comprising 54 929 people with schizophrenia and 223 097 with data on PSs/PEs. Compared with White individuals, Black individuals had increased risk of schizophrenia (pooled odds ratio [OR], 2.07; 95% CI, 1.64-2.61) and PSs/PEs (pooled standardized mean difference [SMD], 0.10; 95% CI, 0.03-0.16), Latinx individuals had higher risk of PSs/PEs (pooled SMD, 0.15; 95% CI, 0.08-0.22), and individuals classified as other ethnoracial group were at significantly higher risk of schizophrenia than White individuals (pooled OR, 1.81; 95% CI, 1.31-2.50). The results regarding CHR-P studies were mixed and inconsistent. Sensitivity analyses showed elevated odds of schizophrenia in Asian individuals in inpatient settings (pooled OR, 1.84; 95% CI, 1.19-2.84) and increased risk of PEs among Asian compared with White individuals, specifically in college samples (pooled SMD, 0.16; 95% CI, 0.02-0.29). Heterogeneity across studies was high, and there was substantial risk of bias in most studies.Conclusions and RelevanceFindings of this systematic review and meta-analysis revealed widespread ethnoracial risk variation across multiple psychosis outcomes. In addition to diagnostic, measurement, and hospital bias, systemic influences such as structural racism should be considered as drivers of ethnoracial disparities in outcomes across the psychosis continuum in the US.

AbstractThe incidence of Hepatocellular carcinoma (HCC) and HCC‐related deaths have remarkably increased over the recent decades. It has been reported that β‐catenin activation can be frequently observed in HCC cases. This study identified the integrin‐linked kinase‐associated phosphatase (ILKAP) as a novel β‐catenin‐interacting protein. ILKAP is localized both in the nucleus and cytoplasm and regulates the WNT pathway in different ways. First, it is demonstrated that ILKAP activates the WNT pathway in HCC cells by increasing the protein level of β‐catenin and other proteins associated with the WNT signaling, such as c‐Myc and CyclinD1. Next, it is shown that ILKAP promotes the metastasis of HCC both in vitro and in vivo in a zebrafish xenograft model. It is also found that ILKAP dephosphorylates the GSK3β and CK1, contributing to the reduced ubiquitination of β‐catenin. Furthermore, it is identified that ILKAP functions by mediating binding between TCF4 and β‐catenin to enhance expression of WNT target genes. Taken together, the study demonstrates a critical function of ILKAP in metastasis of HCC, since ILKAP is crucial for the activation of the WNT pathway via stabilization of β‐catenin and increased binding between TCF4 and β‐catenin.
Epigenetics as a Key Factor in Prostate Cancer
Authors: Enikeeva Kadriia , Rafikova Guzel , Sharifyanova Yuliya , Mulyukova Diana , Vanzin Alexandr , Pavlov Valentin 
Published: February 2024

AbstractNowadays, prostate cancer is one of the most common forms of malignant neoplasms in men all over the world. Against the background of increasing incidence, there is a high mortality rate from prostate cancer, which is associated with an inadequate treatment strategy. Such a high prevalence of prostate cancer requires the development of methods that can ensure early detection of the disease, improve the effectiveness of treatment, and predict the therapeutic effect. Under these circumstances, it becomes crucial to focus on the development of effective diagnostic and therapeutic approaches. Due to the development of molecular genetic methods, a large number of studies have been accumulated on the role of epigenetic regulation of gene activity in cancer development, since it is epigenetic changes that can be detected at the earliest stages of cancer development. The presence of epigenetic aberrations in tumor tissue and correlations with drug resistance suggest new therapeutic approaches. Detection of epigenetic alterations such as CpG island methylation, histone modification, and microRNAs as biomarkers will improve the diagnosis of the disease, and the use of these strategies as targets for therapy will allow for greater personalization of prostate cancer treatment.

AbstractPolar materials, with intrinsic polarization effects, present significant potential for photo(electro)catalysis. However, the available natural polar materials in this field are quite scarce, due to the requisite structural non‐centrosymmetry. Defect engineering emerges as a promising avenue for tuning material symmetry, yet achieving the transition from centrosymmetric to non‐centrosymmetric structures and optimizing associated polarization effects remains challenging. This study demonstrates symmetry breaking in centrosymmetric 3R‐delafossite AgFeO2 through ordered oxygen defects introduction, yielding substantial macroscopic polarization. The transition is achieved via annealing post‐treatment of co‐precipitation‐hydrothermal AgFeO2 samples, with precision in oxygen defects control by tailoring annealing conditions. Experimental characterizations reveal ordered interstitial oxygen and disordered oxygen vacancies. Density functional theory calculations indicate a higher propensity for the formation of disordered oxygen vacancies compared to ordered ones, while ordered interstitial oxygen is more easily formed than its disordered counterpart. Resultant macroscopic polarization enhances photoelectrochemical performance, with photocurrent density increasing from 0.79 to 2.95 µA cm−2. Coupling macroscopic and spin polarization via external electric and magnetic fields further enhances photocurrent density (≈18.44 µA cm−2). These findings provide reference cases and strategies for applying polarization effects in photo(electro)catalytic technology.
Smart Multiple Photoresponsive Tongue for Sensing Umami, Sour and Bitter Tastes Based on Tb3+ Functionalized Hydrogen‐Bonded Organic Frameworks
Authors: Zhang Zishuo , Yan Bing 
Published: February 2024

AbstractArtificial tongues have attracted increasing attention for the perception abilities of five basic tastes. However, simple and versatile identification of different tastes is a formidable challenge for bionic taste sensor. Enriching photoluminescence mechanisms to improve possibilities of multiple optical responses is conducive to simplify the sensor array. Herein, a single sensor Tb@MCATMA (Tb@1) is developed displaying dual‐emissions of both green fluorescence and deep‐blue phosphorescence by ternary co‐assembly of Tb3+, trimesic acid (TMA) and a 2D hydrogen‐bonded organic framework of melamine and cyanuric acid, MCA HOF. This sensor is capable of imitating the human gustatory system to identify and discriminate umami (disodium 5′‐inosinate and disodium 5′‐guanylate), sour (citric acid and oxalic acid) and bitter (2‐furaldehyde and 5‐hydroxymethylfurfural) substances through the diverse photoresponsive modes. Upon excitation wavelength as additional variable, the sensor can further collect the individual “fingerprint information” of six analytes related to tastes and quantitatively detect them with high accuracy. Moreover, the sensing mechanism of each analyte is explored in detail and substantiate that the uniform photoresponsive modes elicited by distinct analytes stem from the shared sensing mechanism. This work provides a facile and powerful sensor platform for taste perception to develop artificial photoresponsive tongue applicable to bionic gustatory system.
