Sentence context and fundamental frequency (F0) contours are important factors to speech perception and comprehension. In Chinese-Mandarin, lexical tones can be distinguished by the F0 contours. Previous studies found healthy people could use the cue of context to recover the phonological representations of lexical tones from the altered tonal patterns to comprehend the sentences in quiet condition, but can not in noise environment. Lots of research showed that patients with schizophrenia have deficits of speech perception and comprehension...

REVIEW
Ray Cody Mayo, Jessica Leung
Tracing the use of computers in the radiology department from administrative functions through image acquisition, storage, and reporting, to early attempts at improved diagnosis, we begin to imagine possible new frontiers for their use in exam interpretation. Given their initially slow but ultimately substantial progress in the noninterpretive areas, we are left desiring and even expecting more in the interpretation realm. New technological advances may provide the next wave of progress and radiologists should be early adopters...

Background: Whether trauma exposure itself or consequent posttraumatic stress disorder (PTSD) is primarily responsible for smoking and failure to quit remains unclear. Methods: A cohort of male Australian Vietnam veterans (N = 388) was interviewed twice, 22 and 36 years after their return to Australia using standardized psychiatric diagnostic and health interviews and assessment of combat exposure. The smoking trajectory over time revealed a spectrum of outcomes (never smoked, early quitters, late quitters, continuing smokers)...

Archana Kadam, Anand Pandit, Sanjay Patole
The authors present a case of Fragile X syndrome (FXS) in siblings from an Indian family with no developmental delay in previous generations. The boy presented with developmental delay, autistic features and defiant behaviours that raised clinical suspicion. He also had congenital diaphragmatic hernia (CDH). Social anxiety and difficulty in making friends were the subtle features in his sister with dull normal intelligence. FXS was confirmed by clinical features and DNA testing. Intervention was initiated for both the siblings...

Within the last generation, the management of patients with heart disease has been transformed by advances in drug treatments, interventions and diagnostic technologies. The management of arterial hypertension saw beta-blockers demoted from first- to third-line treatment. Recent studies suggest that the goal of treatment may have to change to lower systolic blood pressures to prevent long-term organ damage. Today less than 15% of coronary revascularizations are surgical and more than 85% are done by interventional cardiologists inserting coronary stents...

The Boston Naming Test (BNT) is one of the most commonly used naming measures in neuropsychology. Although research in the older adult population has shown that African-American (AA) adults perform more poorly on the BNT than non-Hispanic White American (WA) adults, these findings have yet to be replicated in younger adults. The BNT and measures of word reading (WJ-Letter Word ID) and vocabulary (Wechsler Abbreviated Scale of Intelligence Vocabulary) were administered to 50 WA and 33 AA young adults. Performance was age-normed based on published norms and transformed into z-scores...

This study investigated the degree to which litigants/insurance claimants sustaining Nonimpact mild traumatic brain injury (mTBI) in motor vehicle accidents differed from compensation-seeking motor vehicle accident victims that suffered Impact mTBI in terms of neuropsychological decline/recovery, using as a control litigants/insurance claimants that did not experience mTBI in motor vehicle accidents. A clinical index (C-Voc) was employed as the dependent measure for decline/recovery, consisting of T-score algebraic differences between a highly sensitive neurocognitive measure (Category Test) and a relatively insensitive "hold" measure (Wechsler Adult Intelligence Scale Vocabulary subtest)...

Cell-penetrating peptides (CPPs), also called "Trojan-Horse" peptides, have been used for facilitating intracellular delivery of numerous diverse cargoes and even nanocarriers. However, the lack of targeting specificity ("wildness" or nonselectivity) of CPP-nanocarriers remains an intractable challenge for many in vivo applications. In this work, we used an intelligent "peptide-gathering mechanical arm" (Int PMA) to curb CPPs' wildness and enhance the selectivity of R9-liposome-based cargo delivery for tumor targeting...

Haptic memory, from the interaction of skin and brain, can not only perceive external stimuli but also memorize it after removing the external stimuli. For the mimicry of human sensory memory, a self-powered artificial tactile memorizing system were developed by coupling bionic electronic skin and nonvolatile RRAM. The tribotronic nanogenerator is utilized as electronic skin to transform the touching signal into electric pulse, which will be programmed into the artificial brain: RRAM. Owing to the advanced structural designs and accurately parameter matching, including the output voltages and the resistances in different resistive states, the artificial brain can be operated at self-powered mode to memorize the touch stimuli with the responsivity up to 2000%...

David W Evans, Mirko Uljarević
Recent work has demonstrated that variability in probands' phenotypes, including physical features, cognitive abilities, social functioning, and other developmental domains, is influenced by parental traits. Here we examine the role of parental education as a factor contributing to the variability of intelligence quotient (IQ) of offspring with trisomy 21. Participants were 43 probands with trisomy 21, aged 4-21 years of age, and their parents. Data were collected on parental education, and a bi-parental mean education score (BMES) was calculated...

BACKGROUND: The symptoms and their progression in amyotrophic lateral sclerosis (ALS) are typically studied after the diagnosis has been confirmed. However, many people with ALS already have severe dysarthria and loss of adequate speech at the time of diagnosis. Speech-and-language therapy interventions should be targeted timely based on communicative need in ALS. AIMS: To investigate how long natural speech will remain functional and to identify the changes in the speech of persons with ALS...

A 54-year-old man was admitted to the intensive care unit with an aneurysmal subarachnoid hemorrhage and subsequently underwent mechanical ventilation and received neuromuscular blocking drugs to control refractory elevated intracranial pressure. During quantitative EEG monitoring, an automated alert was triggered by the train of four peripheral nerve stimulation artifacts. Real-time feedback was made possible due to remote monitoring. This case illustrates how computerized, automated artificial intelligence algorithms can be used beyond typical seizure detection in the intensive care unit for remote monitoring to benefit patient care...

The aim of the present study was to explore the subtypes of offenders based on psychopathic traits in a sample of 127 adult homicide offenders (n=40.3% convicted of murder, n=32.6% convicted of aggravated murder, n=27.1% convicted of attempted murder). A two-step cluster analysis of the four factors of psychopathy yielded three clusters, which were then compared on the general dimensions of personality defined by the HEXACO model, intelligence, sadism and psychopathology variables conceptualized by the MMPI-202...

BACKGROUND AND OBJECTIVE: In countries with high prevalence of tuberculosis (TB), clinicians often diagnose tuberculous pleural effusion (TPE) by using diagnostic tests, which have not only poor sensitivity, but poor availability as well. The aim of our study is to develop a new artificial intelligence based diagnostic model that is accurate, fast, non-invasive and cost effective to diagnose TPE. It is expected that a tool derived based on the model be installed on simple computer devices (such as smart phones and tablets) and be used by clinicians widely...

BACKGROUND AND OBJECTIVE: T-cell epitope structure identification is a significant challenging immunoinformatic problem within epitope-based vaccine design. Epitopes or antigenic peptides are a set of amino acids that bind with the Major Histocompatibility Complex (MHC) molecules. The aim of this process is presented by Antigen Presenting Cells to be inspected by T-cells. MHC-molecule-binding epitopes are responsible for triggering the immune response to antigens. The epitope's three-dimensional (3D) molecular structure (i...

Alexis D J Makin
The brain continuously maintains a current representation of its immediate surroundings. Perceptual representations are often updated when the world changes, e.g., when we notice an object move. However, we can also update representations internally, without incoming signals from the senses. In other words, we can run internal simulations of dynamic events. This ability is evident during mental object rotation. These uncontroversial observations lead to an obvious question that nevertheless remains to be answered: How does the brain control the speed of dynamic mental simulations? Is there a central rate controller or pacemaker module in the brain that can be temporarily coupled to sensory maps? We can refer to this as the common rate control theory...

Bicycle frames made of carbon fibre are extremely popular for high-performance cycling due to the stiffness-to-weight ratio, which enables greater power transfer. However, products manufactured using carbon fibre are sensitive to impact damage. Therefore, intelligent nondestructive evaluation is a required step to prevent failures and ensure a secure usage of the bicycle. This work proposes an inspection method based on active thermography, a proven technique successfully applied to other materials. Different configurations for the inspection are tested, including power and heating time...
