Margaret Frye, Lauren Bachan
This paper examines the decline in non-numeric responses to questions about fertility preferences among women in the developing world. These types of response-such as 'don't know' or 'it's up to God'-have often been interpreted through the lens of fertility transition theory as an indication that reproduction has not yet entered women's 'calculus of conscious choice'. However, this has yet to be investigated cross-nationally and over time. Using 19 years of data from 32 countries, we find that non-numeric fertility preferences decline most substantially in the early stages of a country's fertility transition...

Overlay control is of vital importance to good device performances in semiconductor manufacturing. In this work, the differential Mueller matrix calculus is introduced to investigate the Mueller matrices of double-patterned gratings with overlay displacements, which helps to reveal six elementary optical properties hidden in the Mueller matrices. We find and demonstrate that, among these six elementary optical properties, the linear birefringence and dichroism, LB' and LD', along the ± 45° axes show a linear response to the overlay displacement and are zero when the overlay displacement is absent at any conical mounting...

For a very severely mentally disabled, deaf and blind man, it was always very difficult to carry out dental check-ups, diagnosis and treatment, even with pharmacologic support. The man cannot communicate pain. When caries and calculus were diagnosed, the man was treated under general anaesthesia. During this treatment session he was also found to have severe periodontal disease and peri-apical problems. The legal representative of the patient was unavailable for consultation on changes to the pre-prepared preliminary treatment plan...

Conflicting evidence exists concerning the supplementation of vitamin D in knee osteoarthritis condition. This systematic literature review was done to explore the effects of vitamin D supplementation in the management of knee osteoarthritis. Electronic literature search was done in databases like PubMed(®), Embase(®), and Cochrane CENTRAL from inception to 6th July 2016. The quality of included Randomized Controlled Trials (RCTs) was assessed using Cochrane risk of bias tool. We considered change in Western Ontario and McMaster Universities (WOMAC) index, Visual Analog Scale (VAS) and Functional Pain Score (FPS) as the primary outcome measure...

Yann Zerlaut, Alain Destexhe
In this study, we present a theoretical framework combining experimental characterizations and analytical calculus to capture the firing rate input-output properties of single neurons in the fluctuation-driven regime. Our framework consists of a two-step procedure to treat independently how the dendritic input translates into somatic fluctuation variables, and how the latter determine action potential firing. We use this framework to investigate the functional impact of the heterogeneity in firing responses found experimentally in young mice layer V pyramidal cells...

BACKGROUND: Laparoscopic common bile duct exploration (LCBDE) has been widely promoted in recent years as a safe and effective treatment for choledocholithiasis. However, there are no standard guidelines for the treatment of patients who have concomitant hepatolithiasis of the left liver and abdominal adhesions. The aim of the current research was to compare the outcomes of open versus laparoscopic common bile duct exploration with left hepatectomy (OCBDH vs. LCBDH) in patients with choledocholithiasis concomitant with left-sided hepatolithiasis, and to evaluate the safety and feasibility of laparoscopic surgery for choledocholithiasis in patients with abdominal adhesions...

BACKGROUND While uncommon, iliopsoas abscesses can become the underlying cause of a fever of unknown origin. Even in such cases, it is considered rare for an iliopsoas abscess to extend into the subcutaneous space. CASE REPORT A 74-year-old woman with a history of schizophrenia was referred to our hospital with a high-grade fever. The patient was unaware of her febrile status prior to admission. There was no previous hospital admission. Examination revealed a non-tender mass in the lower right back that the patient had been aware of for approximately 1 month...

A 74-year-old man undergoing rehabilitation after pneumonia developed right upper quadrant abdominal pain. Five days earlier he had been commenced on apixaban for a new diagnosis of atrial fibrillation. Ultrasound and CT scans revealed an acalculous grossly thickened gallbladder, with high attenuation non-echogenic material both within and surrounding the structure. Active contrast extravasation was seen at the neck. On laparotomy, a perforated internally bleeding gallbladder containing a single calculus was found, with significant free blood within the abdomen...

Calculus migration is a common problem during ureteroscopic laser lithotripsy procedure to treat urolithiasis. A conventional experimental method to characterize calculus migration utilized a hosting container (e.g., a "V" grove or a test tube). These methods, however, demonstrated large variation and poor detectability, possibly attributed to the friction between the calculus and the container on which the calculus was situated. In this study, calculus migration was investigated using a pendulum model suspended underwater to eliminate the aforementioned friction...

In this paper, we consider a low initial population model. Our aim is to study the periodicity computation of this model by using neutral differential equations, which are recognized in various studies including biology. We generalize the neutral Rayleigh equation for the third-order by exploiting the model of fractional calculus, in particular the Riemann-Liouville differential operator. We establish the existence and uniqueness of a periodic computational outcome. The technique depends on the continuation theorem of the coincidence degree theory...

An adult, male, wild-caught, laboratory-housed green anole (Anolis carolinensis) on a locomotor performance study was presented for anorexia. The anole exhibited a 26% weight loss and a thin body condition but was otherwise alert and active. Despite supportive care, the anole's clinical condition deteriorated, necessitating euthanasia. Postmortem examination revealed a 4.5 mm × 2.5-mm cystic calculus, which consisted entirely of sodium urate. Here we describe the clinical findings and locomotor consequences of this disease in a green anole...

Non-contrast chest CT scans are commonly performed while CT scans of the abdomen and pelvis are performed in a select subset of patients; those with limited renal function, an allergy to iodinated contrast, in the setting of suspected renal calculus, retroperitoneal hematoma, common duct calculus, abdominal aortic aneurysm with or without rupture, and in patients undergoing a PET-CT scan. In the absence of intravenous contrast, vascular structures may prove challenging to evaluate, yet their assessment is an important component of every non-contrast CT examination...

BACKGROUND: Prediction of periodontitis development is challenging. Use of oral health related data alone, especially in young population might underestimate disease risk. This study investigated the accuracy of oral, systemic and socioeconomic data on estimating periodontitis development in a population-based prospective cohort. MATERIALS AND METHODS: General health and sociodemographic information were collected throughout the life-course of the individuals. Oral examinations were performed at ages 24 and 31 in the 1982 Pelotas cohort...
