Injection Molding of Encapsulated Diffractive Optical Elements.

Microstructuring techniques, such as laser direct writing, enable the integration of microstructures into conventional polymer lens systems and may be used to generate advanced functionality. Hybrid polymer lenses combining multiple functions such as diffraction and refraction in a single component become possible. In this paper, a process chain to enable encapsulated and aligned optical systems with advanced functionality in a cost-efficient way is presented.

The QICK (Quantum Instrumentation Control Kit): Readout and control for qubits and detectors.

We introduce a Xilinx RF System-on-Chip (RFSoC)-based qubit controller (called the Quantum Instrumentation Control Kit, or QICK for short), which supports the direct synthesis of control pulses with carrier frequencies of up to 6 GHz. The QICK can control multiple qubits or other quantum devices. The QICK consists of a digital board hosting an RFSoC field-programmable gate array, custom firmware, and software and an optional companion custom-designed analog front-end board.

Second generation readout for large format photon counting microwave kinetic inductance detectors.

We present the development of a second generation digital readout system for photon counting microwave kinetic inductance detector (MKID) arrays operating in the optical and near-infrared wavelength bands. Our system retains much of the core signal processing architecture from the first generation system but with a significantly higher bandwidth, enabling the readout of kilopixel MKID arrays. Each set of readout boards is capable of reading out 1024 MKID pixels multiplexed over 2 GHz of bandwidth; two such units can be placed in parallel to read out a full 2048 pixel microwave feedline over a 4 GHz-8 GHz band.

Dependence of odontogenic abscess on meteorological parameters: truth or myth?

Objectives: It is still a common belief among dental practitioners that odontogenic abscesses are somehow linked to meteorological parameters. We investigated the influence of different meteorological parameters on the type of surgical abscess treatment (intra- versus extraoral incision) as a measure of the weather-dependent severity of infection.

Materials And Methods: In this retrospective cohort study, we analyzed 841 patients who presented at our outpatient clinic with an odontogenic abscess between 2004 and 2013.

The essential sequence of substance P for locomotion.

In rats the effect of substance P SP (1-11 and SP (5-11) heptapeptide on locomotion in open field was investigated after intrategmental application. SP (1-11) increase the locomotor activity significantly, SP (5-11) heptapeptide do not-do it. The effect of SP(1-11), SP(5-11) heptapeptide, SP(6-11) hexapeptide, and SP(1-4) tetrapeptide on the circadianly organized locomotor activity was researched after i.

[The effect of substance P on the swimming behavior of rats under stressing and nonstressing conditions].

Experiments of acute and chronic stressing were investigated in rats. The behavioural features were analyzed. The acute stressing situation involves a swimming test from which rats can escape by entering a little platform.

[Effect of desaminoocta-pancreozymin on the locomotor activity of rats].

The influence of desaminoocta-pancreozymin (DAO-PZ) was investigated in high and low activity periods by intraperitoneal or intranasal application. DAO-PZ is a CCK-8 derivative in which the N-terminal amino acid (Asp) is exchanged for succinyl acid. A decreasing long lasting effect for 3 to 4 h was always observed in locomotor activity.

Modulation of locomotor activity by substance P in rats.

The effects of intraperitoneally or intracerebrally (DA A-10 area) administered substance P (SP) on locomotor activity of rats were studied in an exact 12-h light/12-h dark cycle changing from dark to light at 6 a.m. SP was administered either at 11 a.

[The role of uncertainty in the conditioned-reflex learning behavior for selected cardiovascular functions].

As a contribution to quantitative analysis of exogenous stress action, the role of probability learning (probability stress, probability affirmation) for selected cardio-vascular functions was studied in 25 albino rats and 8 dogs. It has been shown in the rats learning with probability stress that a dependence exists between stress probability, on the one hand, and conditional-reflectory processes and systolic blood pressure rise, on the other, that is, the pathogenic action of probability stress increases from a probability of p = 1.0 to p = 0.

[Diurnal dynamics of periodicities in conditional-reflex processes in the minute range].

Male adult albino rats living from the 6th week of their lives under conditions of artificial light-dark cycle (16 hrs light, 8 hrs dark) were used to study possible relationships between circadian sensitivity cycles and synchronization of dynamics and the frequency variability of periodicities of reaction times of conditional-reflectory processes with wavelengths in the minute range. The experiments have revealed differences at the time of the activity maximum and minimum of a circadian cycle in the studied parameters of the minute rhythm (mean level of oscillation, mean amplitude, length of period and coupling). In the dark phase (activity maximum) there prevailed an increased level of central-nervous excitation and a tendency towards a higher frequency and diminished coupling of minute periods.

[Dynamics of adaptation and maladaptation phenomena in rats exposed to weak chronic stimulation].

Experiments were carried out with rats to study the influence of disturbing artifical light-dark regimens. The findings are consistent with the definition of "relatively weak stress-stimuli" which, according to R. BAUMANN, can be essential in causing regulation diseases.

[The effect of lesions of the caudate nucleus on the development of hypertonic blood pressure dysregulation due to learning stress].

Male albino rats were used to study the effect of excluding the nucleus caudatus upon the development of a hypertensive dysregulation induced by the load of learning (stress). A 3-week stress exposure considerably restricted learning and memory processes in all the animals with nucleus caudatus lesions. Systolic blood pressure values and adrenal weights were within the physiological range.

[Significance of different social factors active in the course of ontogenesis, for the effectiveness of chronic stress influences upon cerebro-visceral regulation processes of albino rats].

Fifty male albino rats were used to study how social factors (animals kept in large groups with playing-cage character, or in social isolation by solitary maintenance) are reflected in the responsiveness of cerebro-visceral regulation processes to chronic stress exposure. The following results were obtained: Animals kept from the 12.-30.

[Effect of angiotensin II on the conditional relfex response patterns of neurotic albino rats].

The effect of one single dose of 10 ng Angiotensin II/kg body weight upon affirmed conditional-reflectory response patterns (two-dimensional conditional-reflectory decision process and periodicities of conditional-reflectory processes) was studied in 50 male albino rats in which a neutrotically induced hypertensive blood pressure regulation had been elicited by stress exposure for 135 days. Contrary to healthy animals in which Angiotensin II was demonstrated to act in a biphasic manner, the neurotic animals revealed a monophasic action manifesting itself by a generalized centralnervous excitation. It was noticed, furthermore, that the information processing and regulatory processes of the CNS are considerably disturbed.

[Biphasic effect of angiotensin II on conditioned reflectory reaction patterns in albino rats].

40 male albino rats were used to investigate the influence of one single i. v. dose of 10 ng/kg Angiotensin II upon established and stabilized conditional-reflectory response pattern (two-dimensional conditional-reflectory decision process and periodicities of conditional-reflectory processes).
