Assistive Technology Uses and Barriers in the Home and Workplace for Adults With Intellectual and Developmental Disabilities.

Background: Assistive technology (AT) has been successfully used by researchers and practitioners to increase task completion and independence in work and home environments for individuals with intellectual and developmental disabilities. While prior research has shown increased outcomes of incorporating AT into daily tasks, research has also indicated that actual use of AT in these settings is much lower.

Method: The current qualitative study used semi-structured interviews with a sample of 25 adults (22 individuals with intellectual and developmental disabilities and three job coaches) to examine the perceived use and implementation of AT into home and work environments, along with potential challenges and barriers.

Novel treatment approach of localized juvenile spongiotic gingival hyperplasia with use of Nd:YAG laser.

Introduction: This article describes the management of two patients who presented with localized juvenile spongiotic gingival hyperplasia. This disease entity is poorly understood, and literature regarding successful treatment is scant. However, there are common themes to management including proper diagnosis and treatment via removal of the affected tissue.

Considerations for using a removable prosthesis with attachments for a staged approach to a failing implant reconstruction.

Full-arch implant reconstructions are being utilized in clinical practice today. Very often these prostheses are prosthetically driven, but not periodontally maintainable. Often the patient presents to the general practitioner with a failing implant reconstruction, where several fixtures need to be removed and others are maintainable.

Laser-Assisted Therapy for the Treatment of Peri-implantitis. Part I. Clinical Outcomes.

The purpose of this 12-month randomized, controlled clinical trial was to evaluate the efficacy of a monotherapy protocol with the neodymium-doped yttrium aluminum garnet (Nd:YAG) laser for treatment of peri-implantitis. Twenty patients with 36 implants exhibiting probing pocket depths (PPDs) > 4 mm and evidence of radiographic bone loss (RBL) were randomly divided into two groups. The test group was treated with the Nd:YAG laser, and the control group was managed with mechanical debridement only.

Optical evidence of the chiral magnetic anomaly in the Weyl semimetal TaAs.

Chiral pumping from optical electric fields oscillating at terahertz frequencies is observed in the Weyl material TaAs with electric and magnetic fields aligned along both the and axes. Free-carrier spectral weight enhancement is measured directly, confirming theoretical expectations of chiral pumping. A departure from linear field dependence of the Drude weight is observed at the highest fields in the quantum limit, providing evidence of field-dependent Fermi velocity of the chiral Landau level.

Novel Approach to Overcome Limitations Associated With Immediate Implant Placement: Osteotome Technique.

This case series introduces a novel osteotome technique as an alternative to conventional drilling protocols for immediate fixtures. Immediate implant placement is associated with significantly less bone-to-implant contact, and navigating the anatomy of the socket can be difficult. Osteotomy drills remove already-limited bone following atraumatic extractions.

Amniotic Band Syndrome: A Multidisciplinary Care Approach to the Treatment of a Rare Case.

Amniotic band syndrome (ABS) is a rare developmental disorder associated with defects such as syndactyly, facial and/or palatal clefts, and dental anomalies like malformed or impacted teeth. In this report, a patient with ABS was successfully treated with orthodontic, endodontic, and periodontal therapies. Cone beam computed tomography revealed a unique eruptive path of the impacted central incisor through the incisive canal and cleft area.

Lip Repositioning with Vestibular Shallowing Technique for Treatment of Excessive Gingival Display with Various Etiologies.

Improvement of smile esthetics is a major goal of modern dentistry. Various treatment modalities have been proposed to correct excessive gingival display (EGD), depending on the identified etiologies. This study reports on the clinical and patient-centered outcomes of a novel lip repositioning technique with vestibular shallowing approach in the treatment of three types of EGD with varying etiologies.

Mechanisms of Resistance to Folate Pathway Inhibitors in : Deviation from the Norm.

The trimethoprim and sulfamethoxazole combination, co-trimoxazole, plays a vital role in the treatment of infections. Previous studies demonstrated that the BpeEF-OprC efflux pump confers widespread trimethoprim resistance in clinical and environmental isolates, but this is not accompanied by significant resistance to co-trimoxazole. Using the excluded select-agent strain Bp82, we now show that acquired trimethoprim versus co-trimoxazole resistance is mainly mediated by constitutive BpeEF-OprC expression due to mutations or by BpeEF-OprC overexpression due to mutations.

Terahertz photoresponse of black phosphorus.

Two-dimensional black phosphorus is a new material that has gained widespread interest as an active material for optoelectronic applications. It features high carrier mobility that allows for efficient free-carrier absorption of terahertz radiation, even though the photon energy is far below the bandgap energy. Here we present an efficient and ultrafast terahertz detector, based on exfoliated multilayer flakes of black phosphorus.

Tunable Ultrafast Thermal Relaxation in Graphene Measured by Continuous-Wave Photomixing.

Hot electron effects in graphene are significant because of graphene's small electronic heat capacity and weak electron-phonon coupling, yet the dynamics and cooling mechanisms of hot electrons in graphene are not completely understood. We describe a novel photocurrent spectroscopy method that uses the mixing of continuous-wave lasers in a graphene photothermal detector to measure the frequency dependence and nonlinearity of hot-electron cooling in graphene as a function of the carrier concentration and temperature. The method offers unparalleled sensitivity to the nonlinearity, and probes the ultrafast cooling of hot carriers with an optical fluence that is orders of magnitude smaller than in conventional time-domain methods, allowing for accurate characterization of electron-phonon cooling near charge neutrality.

Infrared phonons as a probe of spin-liquid states in herbertsmithite ZnCu(OH)Cl.

We report on temperature dependence of the infrared reflectivity spectra of a single crystalline herbertsmithite in two polarizations-parallel and perpendicular to the kagome plane of Cu atoms. We observe anomalous broadening of the low frequency phonons possibly caused by fluctuations in the exotic dynamical magnetic order of the spin liquid.

Nonlinear Terahertz Absorption of Graphene Plasmons.

Subwavelength graphene structures support localized plasmonic resonances in the terahertz and mid-infrared spectral regimes. The strong field confinement at the resonant frequency is predicted to significantly enhance the light-graphene interaction, which could enable nonlinear optics at low intensity in atomically thin, subwavelength devices. To date, the nonlinear response of graphene plasmons and their energy loss dynamics have not been experimentally studied.

Comparison of Osteotome and Conventional Drilling Techniques for Primary Implant Stability: An In Vitro Study.

It may be difficult to achieve primary stability in the posterior maxilla because of poor quality and quantity of bone. Studies have shown that the osteotome technique immediately increases bone density thereby increasing primary stability. An in vitro study was conducted to compare the stability achieved by the osteotome and conventional drilling techniques in low density bone.

Pulsed Near-IR Photoresponse in a Bi-metal Contacted Graphene Photodetector.

We use an ultra-fast near-infrared pulse coincidence technique to study the time, temperature, and power dependence of the photoresponse of a bi-metal contacted graphene photodetector. We observe two components of the photovoltage signal. One component is gate-voltage dependent, linear in power at room temperature and sub-linear at low temperature-consistent with the hot-electron photothermoelectric effect due to absorption in the graphene.

Tunable Terahertz Hybrid Metal-Graphene Plasmons.

We report here a new type of plasmon resonance that occurs when graphene is connected to a metal. These new plasmon modes offer the potential to incorporate a tunable plasmonic channel into a device with electrical contacts, a critical step toward practical graphene terahertz optoelectronics. Through theory and experiments, we demonstrate, for example, anomalously high resonant absorption or transmission when subwavelength graphene-filled apertures are introduced into an otherwise conductive layer.

Resonance frequency analysis (RFA) and insertional torque (IT) stability comparisons of implants placed using osteotomes versus drilling techniques: A preliminary case study.

Objective: Poor bone density in the posterior maxilla often presents challenges in achieving implant stability. Insertional torque (IT) and resonance frequency analysis (RFA) have been used to objectively monitor the process of osseointegration. This study was designed to quantitatively assess the primary and secondary stability of fixtures placed using the osteotome or conventional drilling technique, in soft bone.

Plasmon-Enhanced Terahertz Photodetection in Graphene.

We report a large area terahertz detector utilizing a tunable plasmonic resonance in subwavelength graphene microribbons on SiC(0001) to increase the absorption efficiency. By tailoring the orientation of the graphene ribbons with respect to an array of subwavelength bimetallic electrodes, we achieve a condition in which the plasmonic mode can be efficiently excited by an incident wave polarized perpendicular to the electrode array, while the resulting photothermal voltage can be observed between the outermost electrodes.

Novel Techniques with the Aid of a Staged CBCT Guided Surgical Protocol.

The case report will present some novel techniques for using a "staged" protocol utilizing strategic periodontally involved teeth as transitional abutments in combination with CBCT guided implant surgery. Staging the case prevented premature loading of the grafted sites during the healing phase. A CBCT following a tenting screw guided bone regeneration procedure ensured adequate bone to place an implant fixture.

Sensitive room-temperature terahertz detection via the photothermoelectric effect in graphene.

Terahertz radiation has uses in applications ranging from security to medicine. However, sensitive room-temperature detection of terahertz radiation is notoriously difficult. The hot-electron photothermoelectric effect in graphene is a promising detection mechanism; photoexcited carriers rapidly thermalize due to strong electron-electron interactions, but lose energy to the lattice more slowly.
