Machine Learning-based Self-powered Acoustic Sensor for Speaker Recognition

Publication date: Available online 14 September 2018Source: Nano EnergyAuthor(s): Jae Hyun Han, Kang Min Bae, Seong Kwang Hong, Hyunsin Park, Jun-Hyuk Kwak, Hee Seung Wang, Daniel Juhyung Joe, Jung Hwan Park, Young Hoon Jung, Shin Hur, Chang D. Yoo, Keon Jae LeeAbstractHerein, we report a new platform of machine learning-based speaker recognition via the flexible piezoelectric acoustic sensor (f-PAS) with a highly sensitive multi-resonant frequency band. The resonant self-powered f-PAS was fabricated by mimicking the operating mechanism of the basilar membrane in the human cochlear. The f-PAS acquired abundant voice information from the multi-channel sound inputs. The standard TIDIGITS dataset were recorded by the f-PAS and converted to frequency components by using a Fast Fourier Transfor...

Investigation of cochlear hair cells and the perception of ultrasound signals in guinea pigs.

Authors: Wang FS, Nie G, Huang CC, Li Q, Li T, Zou Y, Zhang S, Ceng X Abstract We established a specific ultrasound frequency-dependent model of cochlear injury using bone conduction ultrasounds in the inner ear of guinea pigs at 50 kHz and 83 kHz, to explore the effects of bone conduction ultrasound in the cochlea. To establish a unilateral cochlear damage model, the unilateral cochlea was destroyed. The control group consisted of 50 kHz and 83 kHz bone conduction ultrasounds in unaltered guinea pigs. In each group, cerebral blood oxygenation level dependent (BOLD) effects were determined by functional magnetic resonance imaging (fMRI). The cochlear outer hair cell motor protein, Prestin, and the microfilament protein, F-Actin, were detected. We found that bone conduction ultrasou...

The Tip of the Iceberg in Maternally Inherited Diabetes and Deafness.

We report a single case of a patient with MIDD which manifested clinically at 41 years old. In addition to diabetes and deafness, he manifested with seizures, ataxia, myopathy, and hypogonadism. We used established methods for the routine workup of this patient. MIDD is indeed a multisystem condition. A previously undescribed phenotypic feature of MIDD may be hypogonadism.

Acute Unilateral Isolated Oculomotor Nerve Palsy in an Adult Patient with Influenza A.

Authors: Senda J, Araki K, Tachi Y, Watanabe H, Kagawashira Y, Ito M, Atsuta N, Katsuno M, Watanabe H, Sobue G Abstract An otherwise healthy 44-year-old woman exhibited isolated unilateral oculomotor nerve palsy accompanied by an influenza A infection. An intra-orbital MRI scan revealed that her right third intracranial nerve was enlarged and enhanced. She recovered completely during the first month after treatment with oseltamivir phosphate. Although intracranial nerve disorders that result from influenza infections are most frequently reported in children, it is noteworthy that influenza can also cause focal intracranial nerve inflammation with ophthalmoparesis in adults. These disorders can be diagnosed using intra-orbital MRI scans with appropriate sequences and through immunol...

Facial Palsy: Diagnostic and Therapeutic Management

Facial expression is an evolutionary adaption facilitating successful social interaction. Muscles of facial expression are pivotal to nonverbal communication, articulation, and corneal protection. Facial palsy results in functional, communicative, and social impairment with profound negative impact on quality of life and emotional well-being. Congenital absence or acute facial nerve insult results in flaccid paralysis. Ultimate recovery following facial nerve insult lies on a spectrum from persistence of dense paralysis to return of normal function; in between zonal permutations of varying degrees of static and kinetic hypoactivity and hyperactivity and synkinesis exist.

You’re Never Fully Dressed Without a Smile

Whether we like it or not, judgments based on facial appearance play a powerful role in how we treat others and how we ourselves are treated. Psychologists have long known that attractive people achieve better outcomes in practically all walks of life. We have all heard, "You never get a second chance to make a first impression." What is striking is that the judgment during the first impression is made within 1/10th of one second.1

Describing the mandible in patients with craniofacial microsomia based on principal component analysis and thin plate spline video analysis

Craniofacial microsomia (CFM) is most often described as a unilateral malformation of derivatives of the first and second branchial arches. The mandible has been classified using several classification systems. However, all are based on two-dimensional imaging. The aim of this study was to mathematically describe the deformed mandible based on principal component analysis (PCA) in a three-dimensional way. This may aid in defining the flaws in existing surgical corrections of the mandible through the identification of the differences in shape compared with a normal mandible in a holistic view with the help of videos.

Survey of Toxoplasma gondii and Neospora caninum in raccoons (Procyon lotor) from the Czech Republic, Germany and Poland

Publication date: Available online 14 September 2018Source: Veterinary ParasitologyAuthor(s): Aleksandra Kornacka, Aleksandra Cybulska, Marcin Popiołek, Bożena MoskwaAbstractThe studies were carried on raccoons from Poland, Germany and the Czech Republic. Tissue samples from raccoon hearts, lungs and brains were used for molecular examination while meat juice was collected for immunological tests.Antibodies against T. gondii were detected in six out of 44 raccoons (13.6%), while T. gondii DNA was found in 18 (40.9%). Antibodies against N. caninum were found in seven raccoons (15.9%) but no parasite DNA was observed in any sample.DNA of T. gondii was observed in raccoons of both sexes (in 42.3% of females and 38.9% of males) from all three countries. The proportion of raccoons that tested...

Prevalence and molecular characteristics of methicillin-resistant Staphylococcus aureus among nasal carriage strains isolated from emergency department patients and healthcare workers in central Taiwan

ConclusionOverall, a substantial proportion of patients visiting the ED and HCWs harbored CA-MRSA, mostly ST59 strains, in their nares. It is noteworthy that MRSA ST45 strains supplanted ST239 as the second leading nasal MRSA colonization strain in our study. (Source: Journal of Microbiology, Immunology and Infection)
