Atmospheric methane concentrations decreased during the early to middle Holocene; however, the governing mechanisms remain controversial. Although it has been suggested that the mid-Holocene minimum methane emissions are associated with hydrological change, direct evidence is lacking. Here we report a new independent approach, linking hydrological change in peat sediments from the Tibetan Plate...

A chip-scale mid-IR water sensor was developed using silicon nitride (SiN) waveguides coated with poly(glycidyl methacrylate) (PGMA). The label-free detection was conducted at λ=2.6-2.7 μm because this spectral region overlaps with the characteristic O-H stretch absorption while being transparent to PGMA and SiN. Through the design of a hybrid waveguide structure, we were able to tailor the mid...

Understanding processes driving the distribution of mid-water prey such as euphausiids and lanternfish is important for effective management and conservation of their predators. In the vicinity of abrupt topographic features such as banks, seamounts, and shelf-breaks mid-water faunal biomass is often elevated, making these sites candidates for special protection. We investigated the spatial dis...

the study was carried out for a period of 150 days on 120 holstein friesian crossbred dairy cows between mid to late lactation to quantify the influence of body condition score (bcs) on yield and composition of milk. total 12 dairy farms having same housing systems and holding at least 20 crossbred dairy cows per farm between mid to late lactation were selected for this study purposes. bcs of i...

In the mid-1970s, the phrase “small is beautiful” became a counterculture slogan against the industrial threat to the environment and the scarcity of resources. Arguing against excessive materialism and meaningless growth, the late Dr. Ernest Friedrich Schumacher—the author of Small Is Beautiful: Economics as if People Mattered, promoted the use of small-scale technology to benefit both humanki...

BACKGROUND Endovascular treatment of intracranial aneurysms can be technically difficult when the neck is wide. The Solitaire AB stent (Covidien, Irvine, California), the only fully retrieved stent, assists in the coiling of wide-neck intracranial aneurysms. OBJECTIVE To evaluate the mid-term angiographic follow-up of wide-necked aneurysms treated with the Solitaire AB stent. METHODS SOLARE...

The extent and behaviour of glaciers during the mid-Piacenzian warm period illustrate the sensitivity of the cryosphere to atmospheric CO2 concentrations above pre-industrial levels. Knowledge of glaciation during this period is restricted to globally or regionally averaged records from marine sediments and to sparse terrestrial glacial deposits in mid-to-high latitudes. Here we expand the Plio...

A set of coupled ocean-atmosphere simulations using state of the art climate models is now available for the Last Glacial Maximum and the Mid-Holocene through the second phase of the Paleoclimate Modeling Intercomparison Project (PMIP2). This study presents the large-scale features of the simulated climates and compares the new model results to those of the atmospheric models from the first pha...

This study examined the differences among high, mid and low ambiguity tolerance groups in their reading comprehension ability and their metacognitive awareness of reading strategies. To this end, 123 first-year college students majoring in Engineering with an age range of 19-25 were stratified into three groups of high, mid and low ambiguity tolerance to participate in the study. They took part...

BACKGROUND The endurance shuttle walking test (ESWT) has shown good responsiveness to interventions in patients with chronic obstructive pulmonary disease (COPD). However, the minimal important difference (MID) for this test remains unknown, therefore limiting its interpretability. METHODS Patients with COPD who completed two or more ESWTs following pulmonary rehabilitation (n=132; forced exp...
