Title: Prognos- tic and biologic significance of chromosomal imbalances assessed by comparative genomic hybridization in multiple myeloma
Abstract: Cytogenetic abnormalities, evaluated either by karyotype or by fluorescence in situ hybridization (FISH), are considered the most important prognostic factor in multiple myeloma (MM). However, there is no information about the prognostic impact of genomic changes detected by comparative genomic hybridization (CGH). We have analyzed the frequency and prognostic impact of genetic changes as detected by CGH and evaluated the relationship between these chromosomal imbalances and IGH translocation, analyzed by FISH, in 74 patients with newly diagnosed MM. Genomic changes were identified in 51 (69%) of the 74 MM patients. The most recurrent abnormalities among the cases with genomic changes were gains on chromosome regions 1q (45%), 5q (24%), 9q (24%), 11q (22%), 15q (22%), 3q (16%), and 7q (14%), while losses mainly involved chromosomes 13 (39%), 16q (18%), 6q (10%), and 8p (10%). Remarkably, the 6 patients with gains on 11q had IGH translocations. Multivariate analysis selected chromosomal losses, 11q gains, age, and type of treatment (conventional chemotherapy vs autologous transplantation) as independent parameters for predicting survival. Genomic losses retained the prognostic value irrespective of treatment approach. According to these results, losses of chromosomal material evaluated by CGH represent a powerful prognostic factor in MM patients.

Title: Clinically isolated syndromes: a new oligoclonal band test accurately predicts conversion to MS
Abstract: Background: Patients with a clinically isolated demyelinating syndrome (CIS) are at risk of developing a second attack, thus converting into clinically definite multiple sclerosis (CDMS). Therefore, an accurate prognostic marker for that conversion might allow early treatment. Brain MRI and oligoclonal IgG band (OCGB) detection are the most frequent paraclinical tests used in MS diagnosis. A new OCGB test has shown high sensitivity and specificity in differential diagnosis of MS. Objective: To evaluate the accuracy of the new OCGB method and of current MRI criteria (MRI-C) to predict conversion of CIS to CDMS. Methods: Fifty-two patients with CIS were studied with OCGB detection and brain MRI, and followed up for 6 years. The sensitivity and specificity of both methods to predict conversion to CDMS were analyzed. Results: OCGB detection showed a sensitivity of 91.4% and specificity of 94.1%. MRI-C had a sensitivity of 74.23% and specificity of 88.2%. The presence of either OCGB or MRI-C studied simultaneously showed a sensitivity of 97.1% and specificity of 88.2%. Conclusions: The presence of oligoclonal IgG bands is highly specific and sensitive for early prediction of conversion to multiple sclerosis. MRI criteria have a high specificity but less sensitivity. The simultaneous use of both tests shows high sensitivity and specificity in predicting clinically isolated demyelinating syndrome conversion to clinically definite multiple sclerosis.

Title: Effect of shot peening on residual stress and fatigue life of a spring steel
Abstract: This study describes shot peening effects such as shot hardness, shot size and shot projection pressure, on the residual stress distribution and fatigue life in reversed torsion of a 60SC7 spring steel. There appears to be a correlation between the fatigue strength and the area under the residual stress distribution curve. The biggest shot shows the best fatigue life improvement. However, for a shorter time of shot peening, small hard shot showed the best performance. Moreover, the superficial residual stresses and the amount of work hardening (characterised by the width of the X-ray diffraction line) do not remain stable during fatigue cycling. Indeed they decrease and their reduction rate is a function of the cyclic stress level and an inverse function of the depth of the plastically deformed surface layer.

Title: Private traits and attributes are predictable from digital records of human behavior
Abstract: We show that easily accessible digital records of behavior, Facebook Likes, can be used to automatically and accurately predict a range of highly sensitive personal attributes including: sexual orientation, ethnicity, religious and political views, personality traits, intelligence, happiness, use of addictive substances, parental separation, age, and gender. The analysis presented is based on a dataset of over 58,000 volunteers who provided their Facebook Likes, detailed demographic profiles, and the results of several psychometric tests. The proposed model uses dimensionality reduction for preprocessing the Likes data, which are then entered into logistic/linear regression to predict individual psychodemographic profiles from Likes. The model correctly discriminates between homosexual and heterosexual men in 88% of cases, African Americans and Caucasian Americans in 95% of cases, and between Democrat and Republican in 85% of cases. For the personality trait “Openness,” prediction accuracy is close to the test–retest accuracy of a standard personality test. We give examples of associations between attributes and Likes and discuss implications for online personalization and privacy.

Title: Key success factors and their performance implications in the Indian third-party logistics (3PL) industry
Abstract: This paper uses the extant literature to identify the key success factors that are associated with performance in the Indian third-party logistics service providers (3PL) sector. We contribute to the sparse literature that has examined the relationship between key success factors and performance in the Indian 3PL context. This study offers new insights and isolates key success factors that vary in their impact on operations and financial performance measures. Specifically, we found that the key success factor of relationship with customers significantly influenced the operations measures of on-time delivery performance and customer satisfaction and the financial measure of profit growth. Similarly, the key success factor of skilled logistics professionals improved the operational measure of customer satisfaction and the financial measure of profit growth. The key success factor of breadth of service significantly affected the financial measure of revenue growth, but did not affect any operational measure. To further unravel the patterns of these results, a contingency analysis of these relationships according to firm size was also conducted. Relationship with 3PLs was significant irrespective of firm size. Our findings contribute to academic theory and managerial practice by offering context-specific suggestions on the usefulness of specific key success factors based on their potential influence on operational and financial performance in the Indian 3PL industry.

Title: Self-citation is the hallmark of productive authors, of any gender
Abstract: It was recently reported that men self-cite >50% more often than women across a wide variety of disciplines in the bibliographic database JSTOR. Here, we replicate this finding in a sample of 1.6 million papers from Author-ity, a version of PubMed with computationally disambiguated author names. More importantly, we show that the gender effect largely disappears when accounting for prior publication count in a multidimensional statistical model. Gender has the weakest effect on the probability of self-citation among an extensive set of features tested, including byline position, affiliation, ethnicity, collaboration size, time lag, subject-matter novelty, reference/citation counts, publication type, language, and venue. We find that self-citation is the hallmark of productive authors, of any gender, who cite their novel journal publications early and in similar venues, and more often cross citation-barriers such as language and indexing. As a result, papers by authors with short, disrupted, or diverse careers miss out on the initial boost in visibility gained from self-citations. Our data further suggest that this disproportionately affects women because of attrition and not because of disciplinary under-specialization.

Title: Towards the Reuse of Standardized Thesauri Into Ontologies
Abstract: One of the main holdbacks towards a wide use of ontologies is the high building cost. In order to reduce this effort, reuse of existing Knowledge Organization Systems (KOSs), and in particular thesauri, is a valuable and much cheaper alternative to build ontologies from scratch. In the literature tools to support such reuse and conversion of thesauri as well as re-engineering patterns already exist. However, few of these tools rely on a sort of semi-automatic reasoning on the structure of the thesaurus being converted. Furthermore, patterns proposed in the literature are not updated considering the new ISO 25964 standard on thesauri. This paper introduces a new application framework aimed to convert thesauri into OWL ontologies, differing from the existing approaches for taking into consideration ISO 25964 compliant thesauri and for applying completely automatic conversion rules.

Title: Dismantling the “Red Wall” of Colloidal Perovskites: Highly Luminescent Formamidinium and Formamidinium–Cesium Lead Iodide Nanocrystals
Abstract: Colloidal nanocrystals (NCs) of APbX3-type lead halide perovskites [A = Cs+, CH3NH3+ (methylammonium or MA+) or CH(NH2)2+ (formamidinium or FA+); X = Cl–, Br–, I–] have recently emerged as highly versatile photonic sources for applications ranging from simple photoluminescence down-conversion (e.g., for display backlighting) to light-emitting diodes. From the perspective of spectral coverage, a formidable challenge facing the use of these materials is how to obtain stable emissions in the red and infrared spectral regions covered by the iodide-based compositions. So far, red-emissive CsPbI3 NCs have been shown to suffer from a delayed phase transformation into a nonluminescent, wide-band-gap 1D polymorph, and MAPbI3 exhibits very limited chemical durability. In this work, we report a facile colloidal synthesis method for obtaining FAPbI3 and FA-doped CsPbI3 NCs that are uniform in size (10–15 nm) and nearly cubic in shape and exhibit drastically higher robustness than their MA- or Cs-only cousins with similar sizes and morphologies. Detailed structural analysis indicated that the FAPbI3 NCs had a cubic crystal structure, while the FA0.1Cs0.9PbI3 NCs had a 3D orthorhombic structure that was isostructural to the structure of CsPbBr3 NCs. Bright photoluminescence (PL) with high quantum yield (QY > 70%) spanning red (690 nm, FA0.1Cs0.9PbI3 NCs) and near-infrared (near-IR, ca. 780 nm, FAPbI3 NCs) regions was sustained for several months or more in both the colloidal state and in films. The peak PL wavelengths can be fine-tuned by using postsynthetic cation- and anion-exchange reactions. Amplified spontaneous emissions with low thresholds of 28 and 7.5 μJ cm–2 were obtained from the films deposited from FA0.1Cs0.9PbI3 and FAPbI3 NCs, respectively. Furthermore, light-emitting diodes with a high external quantum efficiency of 2.3% were obtained by using FAPbI3 NCs.

Title: Bright Visible-Infrared Light Emitting Diodes Based on Hybrid Halide Perovskite with Spiro-OMeTAD as a Hole-Injecting Layer
Abstract: Hybrid halide perovskites that are currently intensively studied for photovoltaic applications, also present outstanding properties for light emission. Here, we report on the preparation of bright solid state light emitting diodes (LEDs) based on a solution-processed hybrid lead halide perovskite (Pe). In particular, we have utilized the perovskite generally described with the formula CH3NH3PbI(3-x)Cl(x) and exploited a configuration without electron or hole blocking layer in addition to the injecting layers. Compact TiO2 and Spiro-OMeTAD were used as electron and hole injecting layers, respectively. We have demonstrated a bright combined visible-infrared radiance of 7.1 W·sr(-1)·m(-2) at a current density of 232 mA·cm(-2), and a maximum external quantum efficiency (EQE) of 0.48%. The devices prepared surpass the EQE values achieved in previous reports, considering devices with just an injecting layer without any additional blocking layer. Significantly, the maximum EQE value of our devices is obtained at applied voltages as low as 2 V, with a turn-on voltage as low as the Pe band gap (V(turn-on) = 1.45 ± 0.06 V). This outstanding performance, despite the simplicity of the approach, highlights the enormous potentiality of Pe-LEDs. In addition, we present a stability study of unsealed Pe-LEDs, which demonstrates a dramatic influence of the measurement atmosphere on the performance of the devices. The decrease of the electroluminescence (EL) under continuous operation can be attributed to an increase of the non-radiative recombination pathways, rather than a degradation of the perovskite material itself.
