Nanopore‐based Sensing of Individual Nucleic Acid Complexes
Authors: Singer Alon , Meller Amit 
Published: June 2010

AbstractNanopores have emerged as a prominent single‐molecule analytic tool, holding particular promise both for genomic applications and for the fundamental biophysical characterization of biopolymers. The interest in single‐molecule analysis has spurred the development of numerous approaches to solid‐state nanopore fabrication, which offer exceptional robustness to both physical and chemical stresses, as well as control over pore size/shape/location and facilitates parallel detection with nanopore arrays. Nanopores in the 1–5 nm diameter range represent an important size regime for studying nucleic acids, as these pores can translocate nucleic acid molecules only in a linear orunfoldedfashion, enabling readout of local nucleic acid structural alterations. In this review, we focus on the fundamental aspects of nanopore‐based nucleic acid analysis, namely the DNA capture process and the subsequent translocation process. We compile here a multi‐parametric study of DNA molecules spanning a large length scale, and discuss the influence of electrolyte concentrations on the capture and translocation processes. We further discuss the ability of nanopores to identify structural changes in the DNA due to non‐specific binding of small molecules or specific hybridization with peptide nucleic acids probes. Through our continuing efforts at understanding the underlying processes which govern the capture and translocation process, we will be better positioned to harness the inherent abilities of nanopores to interrogate the internal structure of nucleic acids, enabling improved sensing applications at the single‐molecule level.
Thermoluminescence of quartz from Shihu gold deposit, western Hebei province, China: some implications for gold exploration
Authors: Cao Ye , Li Shengrong , Yao Meijuan , Zhang Huafeng 
Published: June 2010

AbstractThermoluminescence (TL) of monomineralic separates have been widely used in various geosciences fields in order to trace the thermal history and aid in prospecting for gold deposits. Quartz is a ubiquitous mineral in the Shihu gold deposit, which is situated in the northern part of the Taihang orogenic belt in the North China craton (NCC). The deposit is hosted by ductile-brittle faults within an Archean metamorphic core complex of the Fuping Group. This deposit is characterized by gold-bearing quartz-polymetallic sulfides and quartz veins. New TL results have been obtained for quartz, in which four type-TL glow curves were identified. The gold-bearing quartz present type III glow curves that consist of two peak glow curves at the middle and high peak temperatures with the similar TL intensity. In addition, the cross-sections of peak temperatures and TL intensity highlight the valuable area where the Au-bearing quartz present weak TL intensity and low-middle peak temperatures. Our results significantly enhance the usefulness of quartz in metallogenic studies of the North China craton and as an indicator mineral in mineral exploration of the Taihang Mountain region.

Summary
Objective: Evaluation of spontaneous infant movements is an important tool for the detection of neurological impairments. One important aspect of this evaluation is the observation of movements which exhibit certain complex properties. This article presents a method to automatically extract segments which contain such complex patterns in order to quantitatively assess them.
Methods: Expert knowledge is represented in a principal component model which captures the term complexity as the multivariate interactions in the kinematic chains of the upper and the lower limb. A complexity score is introduced which is used to quantify the similarity of new movements to this model. It was applied to the recordings of 53 infants which were diagnosed by physicians as normal or pathologic.
Results: Time segments marked as complex (from five infants) by physicians could be detected with a mean accuracy of 0.77 by the automated approach. The median of the best complexityscoresofthepathologicgroup(n = 21) is significantly lower (p = 0.001) than the median of the normal group (n = 27).
Conclusion: Using the complexity score we were able to quantify movement complexity in regard of the understanding of physicians. This could be useful for clinical applications.

Published: June 2010

Summary
Objective: To assess the feasibility to generate a confident image of normal breath sounds (BS) based on the quantitative analysis of multichannel sensors and imaging them in three known clinical classes, i.e., tracheal, bronchial and vesicular, identifying their spatial distribution with high resolution on the posterior thoracic surface.
Methods: Three parametrization techniques, the percentile frequencies, the univariate AR modeling, and the eigenvalues of the covariance matrix were evaluated when applied to BS. These sounds were acquired in twelve healthy subjects by a 5 × 5 sensor array on the posterior thoracic surface plus the sound at the tracheal position, to obtain feature vectors that fed a supervised multilayer neural network. Based on BS classification rate, the spatial distribution of each BS class was obtained by constructing an image using deterministic interpolation.
Results: The univariate AR modeling was the best parametrization technique producing a classification performance of 96% during the validation phase and just 4% of not classified feature vectors. Corresponding values for the percentile frequencies were 92% and 7.7%, whereas for the eigenvalues were 91% and 9.0%.
Conclusion: This work shows that it is possible to generate confident images associated with the distribution of normal BS classes. Therefore, a detailed image about the spatial distribution of BS in humans might be helpful for detecting lung diseases.
Effets des traumatismes relationnels précoces chez l'enfant
Authors: Bonneville-Baruchel Emmanuelle 
Published: June 2010

Résumé	Cet article présente une modélisation du profil psychopathologique des enfants qui ont passé leurs premiers temps de vie dans un environnement caractérisé par le chaos et l’imprévisibilité des relations. Cette modélisation est proposée à partir de l’élaboration d’un matériel clinique. La méthode utilisée repose sur l’analyse d’observations et d’entretiens cliniques, réalisés dans le cadre d’une activité de consultante d’intersecteur et de thérapeute dans un hôpital de jour en pédopsychiatrie. Au cours de la recherche, le profil présenté a été construit comme un paradigme, sous l’appellation « Pathologie des traumatismes relationnels précoces ». Il est apparu que ce profil ne correspond à aucune des catégories nosographiques déjà répertoriées. Il est apparu également que les enfants observés ont été confrontés à des parents en grande difficulté psychique qui n’ont pu s’accorder à leur bébé, et lui ont fait vivre de façon fréquente et répétée des situations de négligence grave et/ou de violence. Dans ce contexte, ces enfants ont expérimenté des interactions qui se sont inscrites en eux comme des expériences traumatiques. L’article propose une analyse de la façon dont ces expériences précoces et le système de défense déployé par ces enfants pour la survie psychique pendant une durée excessive ont généré des troubles graves du développement et du fonctionnement psychique et relationnel. Cette analyse s’attache particulièrement aux défaillances et aux troubles des liens intrapsychiques et intersubjectifs, générant des comportements inadéquats et violents qui apparaissent dès qu’une relation d’attachement s’engage avec un nouvel objet. Elle propose également d’analyser les motifs de reproduction, dans les liens intersubjectifs, des caractéristiques des interactions précoces traumatiques vécues par l’enfant.
L'étude psychanalytique de la dyslexie et de la dysorthographie
Authors: Vereecken Pierre 
Published: June 2010

Résumé	Comme les conceptions organicistes et neuro-psysiologiques de la dyslexie sont très prépondérantes dans la plupart des pays, il reste important que les psychanalystes continuent à montrer clairement la spécificité de leur apport. L’analyse approfondie de deux cas montre sur le vif comment certaines expériences pulsionnelles causent un trouble dyslexique. La psychanalyse peut même montrer en certains cas que l’apparition d’un fantasme inconscient cause immédiatement une libération prononcée de la lecture ou une écriture sans erreurs. Bien que ce phénomène ne soit qu’un premier pas pour arriver à une guérison plus complète, il illustre de façon frappante l’impact du traitement psychanalytique sur ce genre de problèmes.

Résumé	À l’appui d’une situation clinique, cet article se propose de réfléchir au potentiel trophique du recours aux scarifications à l’adolescence. Celles-ci constituent une tentative de prise en charge d’expériences traumatiques antérieures qui se voient réactualisées au moment de l’adolescence. Par sa fonction d’étayage, notamment sensoriel, et grâce au travail de liaison du masochisme érogène fortement sollicité dans les scarifications, le corps s’offre comme surface de projection fantasmatique susceptible de favoriser les possibilités de figuration et d’ouvrir la voie de la symbolisation. La dimension d’externalisation de ce recours en acte comporte une potentialité messagère en attente d’être accueillie et interprétée, au risque sinon de s’inscrire dans un recours compulsif.

Published: June 2010

Nigeria has the fourth highest prevalence of TB and the highest prevalence of Sickle cell anaemia (SCA) in the world. SCA patients have impaired immunity and are vulnerable to TB. Hence, we studied the haematological indices of SCA patients with TB in Nigeria. A total of 23 SCA patients with TB were studied in parallel with equal number of age and sex matched SCA patients without TB. SCA patients with TB had significantly lower haematocrit, higher level of circulating sickle cells (CSCs) and similar level of reticulocyte count in comparison to patients without TB. SCA patients with TB had significantly higher mean WBC count associated with higher frequency of neutrophilia in comparison to those without TB. Monocytosis and eosinopenia were exclusively found in SCA patients with TB at frequencies of 52% and 65% respectively. Lymphocyte and basophil counts were normal in all patients with and without TB. Mean platelet counts were high in both patient groups but the frequency of thrombocytosis was significantly higher in patients with TB. SCA patients with TB had significantly higher mean ESR than their counterparts without the infection. The findings of this study revealed that TB in SCA patients was associated with rising level of CSCs, falling level of haematocrit, sub-optimal reticulocytosis, neutrophilia, monocytosis, thrombocytosis, eosinopenia and rising level of ESR. Hence, SCA patients presenting with these haematological indices should be investigated for TB.

ImportanceAlthough patient-reported outcomes provide valuable insights, these subjective data may not align with objective test results. Hearing loss is a pervasive problem, such that concordance between subjective perceptions of hearing ability and objective audiogram assessments would be beneficial.ObjectivesTo determine (1) whether psychological status is an effect modifier of the association between subjective patient reports of hearing ability and objective audiometry results, and (2) whether any effect modification observed in standard static questionnaires would be either mitigated or exacerbated by adaptive testing based on Item Response Theory analyses.Design, Setting, and ParticipantsThis diagnostic study at a tertiary care center and community-based practice included consecutive adults who presented with queries related to hearing loss. Participants were recruited and enrolled and data analyses occurred from 2022 to 2024.ExposuresParticipants prospectively reported their hearing-specific abilities through either a standard static or adaptive version of the Inner Effectiveness of Auditory Rehabilitation (EAR) scale, alongside validated measures of their mental health and audiometry. Word recognition scores (WRS) and pure tone averages (PTA) were used to analyze audiometric testing.Main Outcomes and MeasuresThe association between subjective Inner EAR results and audiometry was evaluated. Stratified analyses were used to assess for effect modification by psychological status. The results of standard static and adaptive testing were compared.ResultsIn this study of 395 patients (mean [range] age, 55.9 [18-89] years; 210 [53.2%] female), standard static Inner EAR mean scores were appropriately higher in patients with higher (better) WRS (50.7, 95% CI, 46.4-54.9), compared with patients with lower (worse) WRS (34.7, 95% CI, 24.3-45.1). However, among patients with worse mental health, there was no association between standard static Inner EAR scores and WRS. In contrast, adaptive Inner EAR mean scores were significantly higher for those with better WRS, regardless of mental health status. Thus, effect modification was observed in standard static assessments, whereas adaptive testing remained durably associated with audiometry, regardless of mental health.Conclusions and RelevancePsychological status was an effect modifier of the association between standard Inner EAR scale scores and audiometry, with a positive association observed only in those with better mental health. Adaptive testing scores, however, remained significantly associated with audiometry, even when mental status was worse. Adaptive testing may stabilize the association between subjective and objective hearing outcomes.

AbstractRecently, in electric mobilities and stationary energy storage device applications, the development of long‐lasting, low‐cost, and high‐safety lithium‐ion batteries (LIBs) is widely studied. LiFePO4 (LFP) is a core cathode material for LIBs owing to its cost‐effectiveness and high safety. However, it exhibits low electronic conductivity and sluggish Li+ diffusion, hindering the application of LFP cathodes in high‐power battery industries. Herein, a triazole‐motivated electrolyte additive, 1‐(trimethylsilyl)−1H‐benzotriazole (TMSBTA) is presented, for mitigating iron dissolution via HF scavenging, reinforcing the robustness of the solid electrolyte interphase and constructing a cathode–electrolyte interface (CEI) to balance the ion and electron conduction of the CEI on the LFP cathode. Scanning probe microscopy performed in the conductive atomic force microscopy mode indicates that the electronically conductive CEI created by the oxidative decomposition of TMSBTA enables rapid and homogeneous lithiation and delithiation during cycling without morphological changes in the LFP particles. This study elucidates the design principles of the CEI on the LFP cathode and is expected to guide integrated electrolyte additive engineering for LFP‐containing LIBs.

AbstractThe explosive growth of information and its widespread availability underscores the need for robust encryption and anticounterfeiting measures. In this study, CdS quantum dots are engineered (QDs) to manifest multiple visual responses to a single trigger through strategic ligand design. The surface engineering method allows QDs to transition from yellow to black upon photoexcitation‐induced electron transfer from Cd(II) to Cd(0). Surface ligands desorption under hole injection, leading to an increase in QDs size and resulting in a redshift in photoluminescence. This photoexcitation‐induced redox reaction reveals unprecedented photochromism and photoluminescence phenomena, establishing a foundation for advanced information protection measures. Utilizing these QDs, excellent writing performance under UV irradiation is achieved in solid‐state substrates, while a dual‐mode encryption system is realized in gel matrices, opening up new avenues for information encryption as well as cumulative and interactive information protection. Furthermore, the redox reaction of CdS QDs is employed as ink for 3D printing, enabling for the creation of digitally programmable materials with distinct temporally evolving appearances by controlling the oxygen content in the ink to regulate the rate of photochromism. This advancement also sheds light on the progress in 3D printing technology.

AbstractIII–V semiconductors possess high mobility, high frequency response, and detection sensitivity, making them potentially attractive for beyond‐silicon electronics applications. However, the traditional heteroepitaxy of III–V semiconductors is impeded by a significant lattice mismatch and the necessity for extreme vacuum and high temperature conditions, thereby impeding their in situ compatibility with flexible substrates and silicon‐based circuits. In this study, a novel approach is presented for fabricating ultrathin InSb single‐crystal nanosheets on arbitrary substrates with a thickness as thin as 2.4 nm using low‐thermal‐budget van der Waals (vdW) epitaxy through chemical vapor deposition (CVD). In particular, in situ growth has been successfully achieved on both silicon‐based substrates and flexible polyimide (PI) substrates. Notably, the growth temperature required for InSb nanosheets (240 °C) is significantly lower than that employed in back‐end‐of‐line processes (400 °C). The field effect transistor devices based on fabricated ultrathin InSb nanosheets exhibit ultra‐high on‐off ratio exceeding 108 and demonstrate minimal gate leakage currents. Furthermore, these ultrathin InSb nanosheets display p‐type characteristics with hole mobilities reaching up to 203 cm2 V−1 s−1 at room temperatures. This study paves the way for achieving heterogeneous integration of III–V semiconductors and facilitating their application in flexible electronics.

Published: May 2024

AbstractGraphene's wetting transparency offers promising avenues for creating multifunctional devices by allowing real‐time wettability control on liquid substrates via the flow of different liquids beneath graphene. Despite its potential, direct measurement of floating graphene's wettability remains a challenge, hindering the exploration of these applications. The current study develops an experimental methodology to assess the wetting transparency of single‐layer graphene (SLG) on liquid substrates. By employing contact angle measurements and Neumann's Triangle model, the challenge of evaluating the wettability of floating free‐suspended single‐layer graphene is addressed. The research reveals that for successful contact angle measurements, the testing and substrate liquids must be immiscible. Using diiodomethane as the testing liquid and ammonium persulfate solution as liquid substrate, the study demonstrates the near‐complete wetting transparency of graphene. Furthermore, it successfully showcases the feasibility of real‐time wettability control using graphene on liquid substrates. This work not only advances the understanding of graphene's interaction with liquid interfaces but also suggests a new avenue for the development of multifunctional materials and devices by exploiting the unique wetting transparency of graphene.
